The retraction is dependent on the contractile protein thrombosthenin. Clot retraction is used as a measure of platelet function.Blood Coagulation: The process of the interaction of BLOOD COAGULATION FACTORS that results in an insoluble FIBRIN clot.Brain: The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain).

It has fibrin-binding activity and is immunologically different from UROKINASE-TYPE PLASMINOGEN ACTIVATOR. The primary sequence, composed of 527 amino acids, is identical in both the naturally occurring and synthetic proteases.Mucopolysaccharidosis I: Systemic lysosomal storage disease caused by a deficiency of alpha-L-iduronidase (IDURONIDASE) and characterized by progressive physical deterioration with urinary excretion of DERMATAN SULFATE and HEPARAN SULFATE. There are three recognized phenotypes representing a spectrum of clinical severity from severe to mild: Hurler syndrome, Hurler-Scheie syndrome and Scheie syndrome (formerly mucopolysaccharidosis V). Symptoms may include DWARFISM; hepatosplenomegaly; thick, coarse facial features with low nasal bridge; corneal clouding; cardiac complications; and noisy breathing.Fibrinogen: Plasma glycoprotein clotted by thrombin, composed of a dimer of three non-identical pairs of polypeptide chains (alpha, beta, gamma) held together by disulfide bonds. Fibrinogen clotting is a sol-gel change involving complex molecular arrangements: whereas fibrinogen is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products.Blood-Brain Barrier: Specialized non-fenestrated tightly-joined ENDOTHELIAL CELLS with TIGHT JUNCTIONS that form a transport barrier for certain substances between the cerebral capillaries and the BRAIN tissue.Leukoencephalopathies: Any of various diseases affecting the white matter of the central nervous system.Disease Models, Animal: Naturally occurring or experimentally induced animal diseases with pathological processes sufficiently similar to those of human diseases.

Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.Neural Stem Cells: Self-renewing cells that generate the main phenotypes of the nervous system in both the embryo and adult. Neural stem cells are precursors to both NEURONS and NEUROGLIA.Brain Neoplasms: Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.Ultrasonic Therapy: The use of focused, high-frequency sound waves to produce local hyperthermia in certain diseased or injured parts of the body or to destroy the diseased tissue.Blood Coagulation Tests: Laboratory tests for evaluating the individual's clotting mechanism.Hemostatics: Agents acting to arrest the flow of blood. Absorbable hemostatics arrest bleeding either by the formation of an artificial clot or by providing a mechanical matrix that facilitates clotting when applied directly to the bleeding surface. These agents function more at the capillary level and are not effective at stemming arterial or venous bleeding under any significant intravascular pressure.Astrocytes: A class of large neuroglial (macroglial) cells in the central nervous system - the largest and most numerous neuroglial cells in the brain and spinal cord. Astrocytes (from "star" cells) are irregularly shaped with many long processes, including those with "end feet" which form the glial (limiting) membrane and directly and indirectly contribute to the BLOOD-BRAIN BARRIER. They regulate the extracellular ionic and chemical environment, and "reactive astrocytes" (along with MICROGLIA) respond to injury.Fibrinolytic Agents: Fibrinolysin or agents that convert plasminogen to FIBRINOLYSIN.Lymphatic Vessels: Tubular vessels that are involved in the transport of LYMPH and LYMPHOCYTES.Plasminogen: Precursor of plasmin (FIBRINOLYSIN).

It is sometimes used in conjunction with but is distinct from INTERVENTIONAL ULTRASONOGRAPHY.Mice, Inbred C57BLFibrinolysin: A product of the lysis of plasminogen (profibrinolysin) by PLASMINOGEN activators. It is composed of two polypeptide chains, light (B) and heavy (A), with a molecular weight of 75,000. It is the major proteolytic enzyme involved in blood clot retraction or the lysis of fibrin and quickly inactivated by antiplasmins.Image Processing, Computer-Assisted: A technique of inputting two-dimensional images into a computer and then enhancing or analyzing the imagery into a form that is more useful to the human observer.Schizophrenia: A severe emotional disorder of psychotic depth characteristically marked by a retreat from reality with delusion formation, HALLUCINATIONS, emotional disharmony, and regressive behavior.alpha-2-Antiplasmin: A member of the serpin superfamily found in plasma that inhibits the lysis of fibrin clots which are induced by plasminogen activator. It is a glycoprotein, molecular weight approximately 70,000 that migrates in the alpha 2 region in immunoelectrophoresis. It is the principal plasmin inactivator in blood, rapidly forming a very stable complex with plasmin.Brain Mapping: Imaging techniques used to colocalize sites of brain functions or physiological activity with brain structures.Factor XIII: A fibrin-stabilizing plasma enzyme (TRANSGLUTAMINASES) that is activated by THROMBIN and CALCIUM to form FACTOR XIIIA. It is important for stabilizing the formation of the fibrin polymer (clot) which culminates the coagulation cascade.Rats, Sprague-Dawley: A strain of albino rat used widely for experimental purposes because of its calmness and ease of handling. It was developed by the Sprague-Dawley Animal Company.Blood Coagulation Disorders: Hemorrhagic and thrombotic disorders that occur as a consequence of abnormalities in blood coagulation due to a variety of factors such as COAGULATION PROTEIN DISORDERS; BLOOD PLATELET DISORDERS; BLOOD PROTEIN DISORDERS or nutritional conditions.Thrombin: An enzyme formed from PROTHROMBIN that converts FIBRINOGEN to FIBRIN.Cerebral Hemorrhage: Bleeding into one or both CEREBRAL HEMISPHERES including the BASAL GANGLIA and the CEREBRAL CORTEX. It is often associated with HYPERTENSION and CRANIOCEREBRAL TRAUMA.Microglia: The third type of glial cell, along with astrocytes and oligodendrocytes (which together form the macroglia). Microglia vary in appearance depending on developmental stage, functional state, and anatomical location; subtype terms include ramified, perivascular, ameboid, resting, and activated. Microglia clearly are capable of phagocytosis and play an important role in a wide spectrum of neuropathologies. They have also been suggested to act in several other roles including in secretion (e.g., of cytokines and neural growth factors), in immunological processing (e.g., antigen presentation), and in central nervous system development and remodeling.Cells, Cultured: Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.Time Factors: Elements of limited time intervals, contributing to particular results or situations.Hippocampus: A curved elevation of GRAY MATTER extending the entire length of the floor of the TEMPORAL HORN of the LATERAL VENTRICLE (see also TEMPORAL LOBE). The hippocampus proper, subiculum, and DENTATE GYRUS constitute the hippocampal formation. Sometimes authors include the ENTORHINAL CORTEX in the hippocampal formation.Intracranial Embolism: Blocking of a blood vessel in the SKULL by an EMBOLUS which can be a blood clot (THROMBUS) or other undissolved material in the blood stream. Most emboli are of cardiac origin and are associated with HEART DISEASES. Other non-cardiac sources of emboli are usually associated with VASCULAR DISEASES.Aging: The gradual irreversible changes in structure and function of an organism that occur as a result of the passage of time.Neovascularization, Physiologic: The development of new BLOOD VESSELS during the restoration of BLOOD CIRCULATION during the healing process.Rabbits: The species Oryctolagus cuniculus, in the family Leporidae, order LAGOMORPHA. Rabbits are born in burrows, furless, and with eyes and ears closed. In contrast with HARES, rabbits have 22 chromosome pairs.Subarachnoid Hemorrhage: Bleeding into the intracranial or spinal SUBARACHNOID SPACE, most resulting from INTRACRANIAL ANEURYSM rupture. It can occur after traumatic injuries (SUBARACHNOID HEMORRHAGE, TRAUMATIC). Clinical features include HEADACHE; NAUSEA; VOMITING, nuchal rigidity, variable neurological deficits and reduced mental status.Streptokinase: Streptococcal fibrinolysin . An enzyme produced by hemolytic streptococci. It hydrolyzes amide linkages and serves as an activator of plasminogen.

They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)Brain Ischemia: Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.Brain Edema: Increased intracellular or extracellular fluid in brain tissue. Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS). (From Childs Nerv Syst 1992 Sep; 8(6):301-6)Blood: The body fluid that circulates in the vascular system (BLOOD VESSELS). Whole blood includes PLASMA and BLOOD CELLS.Plasminogen Activators: A heterogeneous group of proteolytic enzymes that convert PLASMINOGEN to FIBRINOLYSIN.

It is employed in clinical applications such as NMR Tomography (MAGNETIC RESONANCE IMAGING).Heparin: A highly acidic mucopolysaccharide formed of equal parts of sulfated D-glucosamine and D-glucuronic acid with sulfaminic bridges. The molecular weight ranges from six to twenty thousand. Heparin occurs in and is obtained from liver, lung, mast cells, etc., of vertebrates. Its function is unknown, but it is used to prevent blood clotting in vivo and vitro, in the form of many different salts.Endothelial Cells: Highly specialized EPITHELIAL CELLS that line the HEART; BLOOD VESSELS; and lymph vessels, forming the ENDOTHELIUM. They are polygonal in shape and joined together by TIGHT JUNCTIONS. The tight junctions allow for variable permeability to specific macromolecules that are transported across the endothelial layer.Brain Stem: The part of the brain that connects the CEREBRAL HEMISPHERES with the SPINAL CORD. It consists of the MESENCEPHALON; PONS; and MEDULLA OBLONGATA.Recombinant Proteins: Proteins prepared by recombinant DNA technology.Hemorrhage: Bleeding or escape of blood from a vessel.Swine: Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).Vascular Endothelial Growth Factor A: The original member of the family of endothelial cell growth factors referred to as VASCULAR ENDOTHELIAL GROWTH FACTORS. Vascular endothelial growth factor-A was originally isolated from tumor cells and referred to as "tumor angiogenesis factor" and "vascular permeability factor". Although expressed at high levels in certain tumor-derived cells it is produced by a wide variety of cell types. In addition to stimulating vascular growth and vascular permeability it may play a role in stimulating VASODILATION via NITRIC OXIDE-dependent pathways. Alternative splicing of the mRNA for vascular endothelial growth factor A results in several isoforms of the protein being produced.Arteries: The vessels carrying blood away from the heart.Capillaries: The minute vessels that connect the arterioles and venules.Stroke: A group of pathological conditions characterized by sudden, non-convulsive loss of neurological function due to BRAIN ISCHEMIA or INTRACRANIAL HEMORRHAGES. Stroke is classified by the type of tissue NECROSIS, such as the anatomic location, vasculature involved, etiology, age of the affected individual, and hemorrhagic vs. non-hemorrhagic nature. (From Adams et al., Principles of Neurology, 6th ed, pp777-810)Treatment Outcome: Evaluation undertaken to assess the results or consequences of management and procedures used in combating disease in order to determine the efficacy, effectiveness, safety, and practicability of these interventions in individual cases or series.Pericytes: Unique slender cells with multiple processes extending along the capillary vessel axis and encircling the vascular wall, also called mural cells. Pericytes are imbedded in the BASEMENT MEMBRANE shared with the ENDOTHELIAL CELLS of the vessel. Pericytes are important in maintaining vessel integrity, angiogenesis, and vascular remodeling.Brain Abscess: A circumscribed collection of purulent exudate in the brain, due to bacterial and other infections. The majority are caused by spread of infected material from a focus of suppuration elsewhere in the body, notably the PARANASAL SINUSES, middle ear (see EAR, MIDDLE); HEART (see also ENDOCARDITIS, BACTERIAL), and LUNG. Penetrating CRANIOCEREBRAL TRAUMA and NEUROSURGICAL PROCEDURES may also be associated with this condition. Clinical manifestations include HEADACHE; SEIZURES; focal neurologic deficits; and alterations of consciousness. (Adams et al., Principles of Neurology, 6th ed, pp712-6)Fibrin Clot Lysis Time: A measurement of the time needed for FIBRINOLYSIS to occur.Cerebrovascular Circulation: The circulation of blood through the BLOOD VESSELS of the BRAIN.Kinetics: The rate dynamics in chemical or physical systems.Muscle, Smooth, Vascular: The nonstriated involuntary muscle tissue of blood vessels.Antigens, CD31: Cell adhesion molecules present on virtually all monocytes, platelets, and granulocytes. CD31 is highly expressed on endothelial cells and concentrated at the junctions between them.Cerebral Cortex: The thin layer of GRAY MATTER on the surface of the CEREBRAL HEMISPHERES that develops from the TELENCEPHALON and folds into gyri and sulchi. It reaches its highest development in humans and is responsible for intellectual faculties and higher mental functions.Rats, Wistar: A strain of albino rat developed at the Wistar Institute that has spread widely at other institutions. This has markedly diluted the original strain.Hypoxia, Brain: A reduction in brain oxygen supply due to ANOXEMIA (a reduced amount of oxygen being carried in the blood by HEMOGLOBIN), or to a restriction of the blood supply to the brain, or both. Severe hypoxia is referred to as anoxia, and is a relatively common cause of injury to the central nervous system. Prolonged brain anoxia may lead to BRAIN DEATH or a PERSISTENT VEGETATIVE STATE. Histologically, this condition is characterized by neuronal loss which is most prominent in the HIPPOCAMPUS; GLOBUS PALLIDUS; CEREBELLUM; and inferior olives.RNA, Messenger: RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.Tissue Distribution: Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios.Lymphatic System: A system of organs and tissues that process and transport immune cells and LYMPH.Regional Blood Flow: The flow of BLOOD through or around an organ or region of the body.Angiogenesis Inhibitors: Agents and endogenous substances that antagonize or inhibit the development of new blood vessels.Capillary Permeability: The property of blood capillary ENDOTHELIUM that allows for the selective exchange of substances between the blood and surrounding tissues and through membranous barriers such as the BLOOD-AIR BARRIER; BLOOD-AQUEOUS BARRIER; BLOOD-BRAIN BARRIER; BLOOD-NERVE BARRIER; BLOOD-RETINAL BARRIER; and BLOOD-TESTIS BARRIER. Small lipid-soluble molecules such as carbon dioxide and oxygen move freely by diffusion. Water and water-soluble molecules cannot pass through the endothelial walls and are dependent on microscopic pores. These pores show narrow areas (TIGHT JUNCTIONS) which may limit large molecule movement.Aorta: The main trunk of the systemic arteries.Cell Movement: The movement of cells from one location to another. Distinguish from CYTOKINESIS which is the process of dividing the CYTOPLASM of a cell.Mice, Transgenic: Laboratory mice that have been produced from a genetically manipulated EGG or EMBRYO, MAMMALIAN.Dose-Response Relationship, Drug: The relationship between the dose of an administered drug and the response of the organism to the drug.Veins: The vessels carrying blood away from the capillary beds.Allantois: An extra-embryonic membranous sac derived from the YOLK SAC of REPTILES; BIRDS; and MAMMALS. It lies between two other extra-embryonic membranes, the AMNION and the CHORION. The allantois serves to store urinary wastes and mediate exchange of gas and nutrients for the developing embryo.Endothelium: A layer of epithelium that lines the heart, blood vessels (ENDOTHELIUM, VASCULAR), lymph vessels (ENDOTHELIUM, LYMPHATIC), and the serous cavities of the body.Blood Vessel Prosthesis: Device constructed of either synthetic or biological material that is used for the repair of injured or diseased blood vessels.Mice, Knockout: Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.Lymphangiogenesis: The formation of LYMPHATIC VESSELS.Vasodilation: The physiological widening of BLOOD VESSELS by relaxing the underlying VASCULAR SMOOTH MUSCLE.Vasoconstriction: The physiological narrowing of BLOOD VESSELS by contraction of the VASCULAR SMOOTH MUSCLE.Arterioles: The smallest divisions of the arteries located between the muscular arteries and the capillaries.Brain Infarction: Tissue NECROSIS in any area of the brain, including the CEREBRAL HEMISPHERES, the CEREBELLUM, and the BRAIN STEM. Brain infarction is the result of a cascade of events initiated by inadequate blood flow through the brain that is followed by HYPOXIA and HYPOGLYCEMIA in brain tissue. Damage may be temporary, permanent, selective or pan-necrosis.Signal Transduction: The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.Receptor, TIE-2: A TIE receptor tyrosine kinase that is found almost exclusively on ENDOTHELIAL CELLS. It is required for both normal embryonic vascular development (NEOVASCULARIZATION, PHYSIOLOGIC) and tumor angiogenesis (NEOVASCULARIZATION, PATHOLOGIC).Nerve Tissue ProteinsAngiopoietin-1: The first to be discovered member of the angiopoietin family. It may play a role in increasing the sprouting and branching of BLOOD VESSELS. Angiopoietin-1 specifically binds to and stimulates the TIE-2 RECEPTOR. Several isoforms of angiopoietin-1 occur due to ALTERNATIVE SPLICING of its mRNA.In Situ Hybridization: A technique that localizes specific nucleic acid sequences within intact chromosomes, eukaryotic cells, or bacterial cells through the use of specific nucleic acid-labeled probes.Endothelial Growth Factors: These growth factors are soluble mitogens secreted by a variety of organs. The factors are a mixture of two single chain polypeptides which have affinity to heparin. Their molecular weight are organ and species dependent. They have mitogenic and chemotactic effects and can stimulate endothelial cells to grow and synthesize DNA. The factors are related to both the basic and acidic FIBROBLAST GROWTH FACTORS but have different amino acid sequences.Animals, Newborn: Refers to animals in the period of time just after birth.Molecular Sequence Data: Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.Vascular Endothelial Growth Factor Receptor-2: A 200-230-kDa tyrosine kinase receptor for vascular endothelial growth factors found primarily in endothelial and hematopoietic cells and their precursors. VEGFR-2 is important for vascular and hematopoietic development, and mediates almost all endothelial cell responses to VEGF.Brain Damage, Chronic: A condition characterized by long-standing brain dysfunction or damage, usually of three months duration or longer. Potential etiologies include BRAIN INFARCTION; certain NEURODEGENERATIVE DISORDERS; CRANIOCEREBRAL TRAUMA; ANOXIA, BRAIN; ENCEPHALITIS; certain NEUROTOXICITY SYNDROMES; metabolic disorders (see BRAIN DISEASES, METABOLIC); and other conditions.Microscopy, Electron, Scanning: Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.

Posterior reversible encephalopathy syndrome is a clinico-neuroradiological entity characterized by headache, vomiting, altered mental status, blurred vision and seizures with neuroimaging studies demonstrating white-gray matter edema involving predominantly the posterior region of the brain. We report a 47-year-old Caucasian man with liver cirrhosis who developed posterior reversible encephalopathy syndrome following an upper gastrointestinal hemorrhage and who was managed with induced hypothermia for control of intracranial hypertension and continuous veno-venous hemodiafiltration for severe hyperammonemia. We believe this is the first documented case report of posterior reversible encephalopathy syndrome associated with cirrhosis as well as the first report of the use of induced hypothermia and continuous veno-venous hemodiafiltration in this setting.

AU - Ammar, T.. AU - Douglas, A. C.. PY - 2012/12. Y1 - 2012/12. N2 - Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiologic condition that typically demonstrates symmetric occipitoparietal vasogenic edema on CT and MR imaging. The vasogenic edema typically resolves over a period of days to weeks if the underlying hemodynamic abnormality is promptly corrected. Less commonly, PRES may be complicated by hemorrhage or cytotoxic edema that restricts diffusion and usually involves the cerebral cortex. Cortical laminar necrosis (CLN) is a sequela of cerebral energy depletion, resulting in selective necrosis of the most metabolically active cortical layers. Cortical hemorrhage is an atypical feature of CLN. We present a unique PRES case with imaging features of both CLN and CT negative ...
Many intracranial lesions have cystic features on MR images. The cystic appearance arises from an abrupt transition between tissues with different physicochemical properties and corresponds histologically to a wide spectrum of diseases. Cystic intracranial lesions may correspond either to true cysts (lined by epithelial, ependymal, or meningothelial cells), porencephalic pseudocysts (all containing CSF), dermoid and epidermoid cysts (containing keratin), the appearance of which on MR images may simulate CSF, or may correspond to pseudocystic neoplastic or inflammatory lesions because of the accumulation either of necrotic or of intercellular myxoid or proteinaceous material (1, 2). From a clinical point of view, it is important to be able to distinguish between those cystic intracranial lesions that require surgery and those that do not, because the former represent a potentially life-threatening condition for the patient (neoplastic or inflammatory) whereas the latter (maldevelopmental or ...
Outcome of acute encephalopathy/encephalitis was compared in children treated with early or delayed cooling in a study at St Marys Hospital, Fukuoka, and other centers in Japan. Children between 1 month and 14 years old, cared for at pediatric intensive care units at 10 Japanese tertiary centers, Jan 1997-July 2008, were retrospectively enrolled. Eight centers provided therapeutic hypothermia within 48 h of diagnosis. Of 43 children, 27 had a preceding viral infection, and 17 were influenza. Acute necrotizing encephalopathy was diagnosed in 8 children, hemorrhagic shock and encephalopathy syndrome in 5, and acute encephalopathy with refractory seizures in 16. The incidence of unfavorable outcome for children cooled after 12 h of diagnosis was invariant with normothermic children but was significantly higher compared with children cooled within 12 h. Younger age ,18 months and marked elevation of serum lactic dehydrogenase (LD) greater than the 75th percentile were associated with severe ...
Posterior reversible encephalopathy syndrome (PRES) is a rare disease characterized by altered mental status, seizures, headache, vomiting and visual disturbances, most often described after transplantation and immunosuppressive therapy. PRES is commonly first diagnosed by the neuroradiologist, rather than the clinician, as it is characterized by very typical magnetic resonance imaging (MRI) features, i.e., hyperintense lesions in the territories of the posterior cerebral artery. Here we report our experience in the Intensive Care Unit (ICU) with a case of tacrolimus-related PRES after liver transplant, presenting with sudden neurological deterioration and diffuse and massive hyperintensities upon brain MRI. Discontinuation of tacrolimus, as prompted by the established literature, permitted the patient to eliminate tacrolimus-associated toxicity, whereas its substitution with everolimus and mycofenolic acid allowed the maintenance of immunosuppression while avoiding acute organ rejection and ...
Investigators from Soochow University, Suzhou, China, studied the possible pathogenetic mechanisms and treatment of posterior reversible encephalopathy syndrome (PRES) observed in 11 cases of pediatric acute lymphoblastic leukemia (ALL) after induction chemotherapy. The clinical symptoms of PRES disappeared after appropriate treatment in most cases, even though induction chemotherapy continued. During the 1-year follow-up, no recurrence of PRES was observed. PRES should be recognized as an important complication of ALL that is reversible when diagnosed and treated early. Of the 11 children, 7 were boys and 4 girls. They were reviewed at an average age of 8.5 years (range, 5-14 years old). During the ALL inductive treatment (VDLD), 4 patients (36%) had an increase in blood pressure. Intrathecal chemotherapy included methotrexate, cytosine arabinoside, and dexamethasone. During the chemotherapy period (days 7 to 30) patients developed acute brain dysfunction, ...
Sepsis-associated encephalopathy (SAE), a diffuse cerebral dysfunction in the absence of direct CNS infection, is associated with increased rates of mortality and morbidity in patients with sepsis. Increased cytokine production and disruption of the blood-brain barrier (BBB) are implicated in the pathogenesis of SAE. The induction of pro-inflammatory mediators is driven, in part, by activation of NF-κΒ. Lipopolysaccharide (LPS), an endotoxin produced by gram-negative bacteria, potently activates NF-κΒ and its downstream targets, including cyclooxygenase-2 (Cox-2). Cox-2 catalyzes prostaglandin synthesis and in the brain prostaglandin, E2 is capable of inducing endothelial permeability. Depletion of polymerase δ-interacting protein 2 (Poldip2) has previously been reported to attenuate BBB disruption, possibly via regulation of NF-κΒ, in response to ischemic stroke. Here we investigated Poldip2 as a novel regulator of NF-κΒ/cyclooxygenase-2 ...

A 41-year-old man with a previous kidney transplant was referred for arterial hypertension and acute renal failure. Initial neurological examination was normal. Laboratory data showed a high serum cyclosporine A concentration. A few hours later, he developed generalised tonic-clonic seizures. The brain computed tomogram was not remarkable, but Glasgow Coma Scale score remained at 8. Mechanical ventilation was required for rapidly progressive hypoxaemia related to Staphylococcus aureus pneumonia and septicaemia. Noradrenaline infusion was needed for only nine hours, with no major drop in mean arterial blood pressure. On day three his Glasgow Coma Scale score was 3/15, with fixed dilated pupils. The brain computed tomogram revealed bilateral hypodense lesions in the posterior areas together with cerebral oedema and the patient was subsequently declared brain dead. We discuss the possibility of a posterior reversible ...

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a well-defined autoimmune disorder. Hashimotos encephalopathy (HE) is a still controversial entity, lacking definite diagnostic criteria. We described a 14-year-old-girl presenting with a clinical picture consistent with the diagnosis of anti-NMDAR encephalitis, confirmed by NMDAR antibody testing. Four years earlier, she had presented a similar episode of acute encephalopathy diagnosed as HE. Anti-NMDAR encephalitis and HE share similar clinical features so that the differential diagnosis can be difficult if specific antibodies are not tested. The correct diagnosis of anti-NMDAR encephalitis is crucial to plan the appropriate management and follow-up, namely in term of oncological screening, since it can be paraneoplastic in origin. We suggest to re-evaluate the clinical history of all subjects with previous HE diagnosis in order to evaluate the possible diagnosis of anti-NMDAR encephalitis and plan the appropriate management of these patients
Abstract: A brief overview of mathematical models of contemporary applied hemodynamics is given. The special attention is paid to questions of development of effective computational algorithms implementing one-dimensional model. For this purpose TVD-monotonized schemes having the second order accuracy both in time and space are used. A number of test problems with analytical solutions are proposed. Questions of convergence and a choice of grid parameters for various schemes are investigated. The approaches using multiscale hemodynamics models are considered. An embedding of one-dimensional model of a single vessel into 0-dimensional model of vascular system is implemented. The possibility of using linear model for considered class problems of hemodynamics is analyzed ...
The radius of the pulmonary arteries and of the descending thoracic aorta in man was measured by angiographic techniques. Simultaneously with angiocardiography, pressure measurements were carried out, permitting calculation of radius-pressure (ΔR/ΔP) relationships. The results obtained by this method are similar to those obtained by other methods in which the vessel radius was measured more directly.. ...
To understand what happens when the heart stops, it is first important to understand the function of the heart. After all, when the heart stops its function ceases. The heart is a hollow organ that is made up of four chambers - right atrium, right ventricle, left atrium and left ventricle. Large blood vessels lead to and away from these chambers. Valves control blood flow between chambers and between the chambers and the large blood vessels.. The heart is a pump that receives low oxygen blood from the rest of the body (in the right atrium) and pushes this blood to the lungs (from the right ventricle). The blood is then oxygenated by the lungs and carbon dioxide is expelled. Then the blood returns to the heart (in the left atrium). From here, ...

Researchers have developed new single-cell sequencing methods that could be used to map the cell origins of various brain disorders, including Alzheimers, Parkinsons, schizophrenia and bipolar disorder.. By analyzing individual nuclei of cells from adult human brains, researchers at the University of California San Diego, Harvard Medical School and Sanford Burnham Prebys Medical Discovery Institute have identified 35 different subtypes of neurons and glial cells and discovered which of these subtypes are most susceptible to common risk factors for different brain diseases.. "There are multiple theories regarding the roots of various brain diseases. Our findings enable us to narrow down and rank which types of cells in the brain carry the most genetic risk for developing these diseases, which can help drug developers pick better targets in the future," said Kun Zhang, a ...
Thanks to misinformation and the mismanagement of infectious waste and bodily fluids, people of all ages are now exposed to an expanding spectrum of brain disease. So are other mammals.. The most common forms of neurodegenerative disease include Alzheimers disease, Parkinsons disease, ALS and Creutzfeldt-Jakob disease-the most aggressive and infectious of them all. According to Nobel Prize Laureate Stanley Prusiner, these brain diseases are part of the same disease spectrum-prion disease. Its also known as transmissible spongiform encephalopathy (TSE). The operative word is transmissible.. Prion disease also includes chronic wasting disease among cervids (deer) and mad cow disease among cattle. Its been found in dozens of mammals..

WEDNESDAY, May 8, 2019 (HealthDay News) -- High levels of a protein linked with the brain disease chronic traumatic encephalopathy (CTE) were found in the cerebrospinal fluid of ex-athletes who suffered multiple concussions, Canadian researchers say.. The protein tau has been tied to CTE, a rare, degenerative brain disease believed to stem from repeated impacts to the head. People with CTE develop symptoms such as dementia, personality disorders or behavior problems.. This study included 22 former professional athletes, average age 56, with a history of multiple concussions. The men included 12 Canadian Football League players, nine hockey players and one snowboarder. They were compared to 12 people with Alzheimers disease and five healthy people.. Researchers checked tau levels in the participants cerebrospinal fluid, which surrounds the spine and brain.. Of the former athletes, 12 (54%) had high levels of tau. Their levels (averaging 349 picograms per ...

New findings that onetime star linebacker Junior Seau had a degenerative brain disease when he shot himself in the chest last May have turned up the heat on the NFL, which claims its doing its best to protect its players and support medical research. The suits, awaiting review by a federal judge in Philadelphia, could be a replay of the tobacco cases -- the long-running and ultimately successful claims by smokers and state governments that the industry hid the lethal risks of its products. The concussion suits nevertheless have potentially huge consequences, both for the NFLs finances and for its safety policies, in light of mounting evidence of the cumulative effects of years of violent gridiron collisions. Seau, who never had a reported concussion in his 20-year career, suffered from a brain disease called chronic traumatic encephalopathy or CTE, National Institutes of Health researchers said last week.

Well, the Wall Street Journal reports that new research reveals iron, copper, zinc and other metals could be linked to Alzheimers and Parkinsons disease. Some scientists theorize that the accumulation of such metals could lead to toxicity that causes brain diseases. And new research with mice shows that reducing excess iron in the brain alleviates the symptoms of Alzheimers. By understanding the role metals play in brain diseases, scientists could be better equipped to develop new treatments for diseases like Alzheimers and Parkinsons ...

Transcription:. According to a new essay written by Dr. Ford Vox, who is a brain specialist in the city of Atlanta, he says that Donald Trump needs to be tested for degenerative brain disease, because he sees all of the warning signs of degenerative brain disease in Donald Trump. Now Dr. Vox is a brain injury specialist, again from the city of Atlanta, Georgia, and he believes that not the recent denture-gate thing, that doesnt point to anything other than bad dental work. What hes talking about is a pattern of behavior that appears to be getting worse in Donald Trump.. He says if you go back and you look at some Donald Trump speeches or interviews or what have you from five or ten years ago, youre going to literally see a different human being. What Donald Trump has morphed into, the way that he speaks, again not counting the slurred word things, that was something wrong with his mouth. The way that he speaks, the words that he uses, his ...
To the Editor:. Intravenous nitroglycerin is a well-recognized treatment of acute hypertension and hypertensive encephalopathy.1 We are reporting a patient presented with posterior reversible encephalopathy syndrome (PRES) secondary to hypertensive crisis who deteriorated when his blood pressure was treated with intravenous nitroglycerin. We, therefore, suggest that nitroglycerine should be discontinued in all patients with hypertensive encephalopathy with worsening neurological status or in the presence of typical radiological findings.. A 63-year-old man with a history of hypertension and diabetes mellitus presented with a severe headache, associated with nausea and vomiting. He had a history of alcohol abuse complicated by liver cirrhosis but denies drinking for many years. His medications include insulin glargine, atenolol 50 mg, gabapentin, zolpidem, and tamsulosin. His blood pressure was 222/110 mm Hg, and his pulse rate was 68 bpm. ...
Angiogenesis is an essential process whereby new blood vessels are formed from pre-existing vessels and occurs under both normal and pathophysiological conditions. growth element receptor 1 (sVEGFR-1). Therefore, FoxC1 appears to control angiogenesis by regulating two unique and opposing mechanisms; if so, vascular development could be identified, at least in part, Elvitegravir by a competitive balance between pro-angiogenic and anti-angiogenic FoxC1-controlled pathways. With this review, we describe the mechanisms by which FoxC1 regulates vessel growth and discuss how these observations could contribute to a more total understanding of the part of FoxC1 in pathological angiogenesis. Intro Under both physiological and pathological conditions, new blood vessels are created from pre-existing vessels through a process called angiogenesis, which is definitely exactly controlled ...
PRES presents with nonspecific signs and symptoms including headaches, confusion, visual disturbances, elevated blood pressure and seizures. Clinical findings are not sufficiently specific to establish the diagnosis, however, magnetic resonance imaging (MRI) pattern is often characteristic and represents an essential component of the diagnosis of PRES. PRES is an acute episode of vasogenic edema in the cerebral white matter, with a predilection for the posterior temporal, parietal and occipital regions. The vasogenic edema is likely due to autoregulatory dysfunction and endothelial dysfunction. The explanation for predilection for the posterior circulation is uncertain. Non enhanced CT shows patchy bilateral white matter nonconfluent hypodensity, and contrast enhanced CT images show variable mild patchy punctuate enhancement. The findings in the subcortical white-matter are hyperintense on T2-weighted images, hypointense or isointense on diffusion-weighted images, and ...
The primary aim of this study is to determine the neuroprotective effect of intravenous administration of autologous cord blood in neonates with severe encephalopathy (hypoxic ischemic encephalopathy or cerebral infarction). It is hypothesized that the administration of autologous cord blood will be safe and well tolerated in neonates with severe encephalopathy. If a neonate is born with signs of moderate to severe encephalopathy and cooled for the encephalopathy, the neonate will receive their own cord blood. The cord blood cells are divided into 3 doses and infused at 24, 48, and 72 hours after the birth. Infants will be randomised to treatment with autologous cord blood and hypothermia or hypothermia only and followed for safety and neurodevelopmental outcome up to 18 months. All infants in both groups will be treated with hypothermia for ...
Posterior reversible encephalopathy syndrome (PRES), also known as hypertensive encephalopathy, is a neurotoxic state that occurs secondary to the inability of posterior circulation to auto-regulate in response to acute changes in blood pressure. Hyperperfusion with resultant disruption of the blood brain barrier results in vasogenic oedema, but not infarction, most commonly in the parieto-occipital regions.. It should not be confused with chronic hypertensive encephalopathy, also know as hypertensive microangiopathy, which results in microhemorrhages in the basal ganglia, pons and cerebellum. ...
The European Union spends just over three euro a year per patient on research into brain disorders - while levels of access to treatment in many Member States are becoming worse, not better, a medical conference organised by the European Brain Council (EBC) heard today.. The EBC unveiled a new report, "The Value of Treatment for Brain Disorders", which highlights the need for more investment into research on neurological and mental diseases and the wide disparities between and within countries relating to treatments, detection and intervention.. More than 165 million Europeans are living with brain disorders such as epilepsy, Alzheimer`s disease, depression and multiple sclerosis; the burden on national health budgets is staggering - rising to more than 800 billion euro a year in direct and indirect costs such as lost earnings and lost tax revenues.. Commenting on the new report, EBC President Professor David Nutt said: "Up ...
PRES is extremely rare, and usually diagnosed by a history of sudden visual impairment in the presence of specific radiological changes on MRI. Bilateral symmetrical hypodensitities in the parieto-occipital areas and cerebellar hemispheres on imaging are characteristic. The condition has been associated with chemotherapy, hypertension, infection and autoimmune disease.1. It is thought to occur from temporary impairment of the blood brain barrier causing vasogenic edema with symptoms of reduced consciousness, seizures, headaches, and typically visual problems.2 Around 26-67% of patients with PRES present with visual symptoms of blurred vision, visual neglect, homonymous hemianopsia, hallucinations or cortical blindness.. Our case is unusual, as PRES caused by pancreatitis has only been reported in very sick patients with other comorbidities. It probably occurred in this case as a result of the systemic inflammatory response.3,4,5,6. Whilst pancreatitis itself ...
Vasogenic oedema due to cerebrovascular autoregulatory dysfunction results in the leakage of fluid into the interstitium. It was considered that vasogenic oedema is the main pathology of PRES by MRI imaging findings. Endogenous-exogenous factors injure the endothelial cells in the brain blood vessels in PRES. Furthermore, ischaemia due to vasospasm accelerates endothelial injury. If there is an increase in blood pressure due to whole-body vasospasm and hypertension, even if it is slight, it is considered that the autoregulatory capacity of the blood-brain barrier and cerebral blood flow collapses immediately. Therefore, it is presumed that vasogenic oedema easily occurs. The reason that PRES often develops with an increase in blood pressure is thought to involve an increase in ...

Small Blood Vessel Problems: when your blood sugars stay too high for a long time, your small blood vessels may be harmed. This can cause problems with your eyes and kidneys. It can also cause problems with blood circulation to your feet and skin. High levels of sugar in your blood make it harder for the red blood cells to squeeze into very small blood vessels in your body. Sugar also makes the walls of your blood vessels less strong. When the red blood cells try to squeeze into the small blood vessels, they damage the vessels even more. This can make your ...

Background and Purpose- Relative signal intensity of acute ischemic stroke lesions in fluid-attenuated inversion recovery (fluid-attenuated inversion recovery relative signal intensity [FLAIR-rSI]) magnetic resonance imaging is associated with time elapsed since stroke onset with higher intensities signifying longer time intervals. In the randomized controlled WAKE-UP trial (Efficacy and Safety of MRI-Based Thrombolysis in Wake-Up Stroke Trial), intravenous alteplase was effective in patients with unknown onset stroke selected by visual assessment of diffusion weighted imaging fluid-attenuated inversion recovery mismatch, that is, in those with no marked fluid-attenuated inversion recovery hyperintensity in the region of the acute diffusion weighted imaging lesion. In this post hoc analysis, we investigated whether quantitatively measured FLAIR-rSI modifies treatment effect of intravenous alteplase. Methods- FLAIR-rSI of stroke lesions was measured relative to signal intensity in a mirrored ...

Abnormal high signal intensity in the occipital lobe white matter, bilaterally, consistent with vasogenic edema. Posterior Reversible Encephalopathy Syndrome (PRES)
MECP2-related severe neonatal encephalopathy has an X-linked pattern of inheritance. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes in each cell. In males, who have only one X chromosome, a mutation in the only copy of the gene in each cell is sufficient to cause the condition. In females, who have two X chromosomes, a mutation in one of the two copies of the gene in each cell is usually sufficient to cause the condition. However, females with a mutation in the MECP2 gene do not develop MECP2-related severe neonatal encephalopathy. Instead, they typically develop Rett syndrome, which has signs and symptoms that include intellectual disability, seizures, and movement problems.. In some cases, males with MECP2-related severe neonatal encephalopathy inherit the mutation from a mother with mild neurological problems or from a mother with no features related to the mutation. A characteristic of X-linked ...

Advanced tests done at the National Institutes of Health on the brain of football star Junior Seau, who committed suicide in May, showed he had signs of a degenerative brain disease, the Associated Press reported.. The examination of Seaus brain showed abnormalities consistent with chronic traumatic encephalopathy (CTE), the kind of injury associated with repetitive head injuries, the AP said.. An initial autopsy on Seau performed by the San Diego County medical examiner found no apparent damage to his brain from years of football. But the Seau family, searching for a reason the 43-year-old Seau took his life, asked for a more in-depth examination by the NIH.. PHOTOS: Junior Seau , 1969 - 2012. Seau killed himself May 2 in his beachfront home in Oceanside with a gunshot to the chest. He left no note and his live-in girlfriend, who was at the gym at the time, told investigators he had given no indication that he was contemplating suicide.. ...
The definitive guide to clinical neurology, the twelfth edition of Brains Diseases of the Nervous System provides detailed coverage of the full range of major neurological conditions, and includes updated sections on genetics, development neurology, and re-written introductory chapters.
When he ended his life last year by shooting himself in the chest, Junior Seau had a degenerative brain disease often linked with repeated blows to the head.. Researchers from the National Institutes of Health said Thursday the former NFL stars abnormalities are consistent with chronic traumatic encephalopathy, or CTE.. The hard-hitting linebacker played for 20 NFL seasons with San Diego, Miami and New England before retiring in 2009. He died at age 43 of a self-inflicted gunshot in May, and his family requested the analysis of his brain.. "We saw changes in his behavior and things that didnt add up with him," his ex-wife, Gina, told The Associated Press. "But (CTE) was not something we considered or even were aware of. But pretty immediately (after the suicide) doctors were trying to get their hands on Juniors brain to examine it.". The NIH, based in Bethesda, Md., studied three unidentified brains, one of which was Seaus, and said the ...
Degenerative brain disease. Coloured single photon emission computed tomography (SPECT) scans of axial sections through the brain of a patient with striatonigral degeneration (SND). SND is a neurodegenerative disease, similar to Parkinsons, that may be present in multisystem atrophy. The scans show areas of neuronal loss (blue and black) at the front of the brain (top). This leads to the symptoms, which include; muscular rigidity, unstable posture, urinary problems, tremor and depression. There is no cure and drugs only alleviate symptoms in the short term. SPECT scans use gamma cameras to detect radioactive tracers, injected into the blood, that accumulate in areas of high metabolic activity. - Stock Image M260/0329
By Hannah Evans, DVM, Veterinary Anesthetist for VNIoC. A 10-year-old female spayed German Shepherd dog presented to the neurology service for new onset of seizure activity. Her previous medical history included hypothyroidism (well-controlled on medication), anal sac adenocarcinoma (surgically removed 2 years prior), and lumbosacral disc disease (surgically treated approximately 4 months prior). Her medications at that time included soloxine, carprofen, gabapentin, and amitriptyline. Levetiracetam was added to her regimen the night prior by the emergency service. Neurologic exam that morning revealed mild paraparesis and proprioceptive ataxia. Differential diagnoses included neoplasia, inflammatory disease, and less likely idiopathic epilepsy given the patients age at time of onset.. An MRI of the brain and skull was recommended under general anesthesia. The dog was classified as an ASA III patient due to the concern for brain disease, but with mild clinical signs. She was ...

Their findings offer hope for a treatment to more than 30,000 Americans who have Huntingtons symptoms and another 200,000 at risk of inheriting the disease. They also could help scientists better understand other fatal brain diseases such as amyotrophic lateral sclerosis and a certain type of dementia, as well as help researchers learn more about normal brain aging.. "We found these kind of traffic jams in cells, and if we can fix the traffic jams we can potentially provide a new avenue for treatment of neurodegenerative disease," said Jonathan Grima, a graduate student in the Johns Hopkins University School of Medicine department of neuroscience whose research was published this week in the journal Neuron.. Grima said its not clear if a drug developed to clear these jams could stop cells from dying, and thus stop progression of Huntingtons, but that is the goal. Grima works in the lab of Dr. Jeffrey Rothstein, director of Hopkins Brain ...
Milwaukee, Wis. - The Medical College of Wisconsin has received a two-year, $377,000 award from the National Institute of Neurological Disorders and Stroke to study the fetal basis of adult brain disease.. The research, which will be led by principal investigator Jeannette Vasquez Vivar, assistant professor of biophysics, will examine the link between oxygen deficit and loss of a key agent in the regulation of the oxidation-reduction process and in neurotransmitter production in the brain. Hypoxia, or oxygen deficit, in the preterm fetal brain is an important gestational complication leading to movement disorders such as cerebral palsy and muscle impairments. The mechanism by which hypoxia causes damage to the developing brain remains unknown, although evidence indicates that oxidative stress plays a role. This mechanism is being investigated in animal models and cell cultures, using several analytical techniques. Related stories. • Medical ...

A review by the American Academy of Neurology on the use of medical marijuana in brain diseases finds certain forms of medical marijuana can help treat some symptoms of multiple sclerosis (MS), but do not appear to be helpful in treating drug-induced (levodopa) movements in Parkinsons disease.
The disease was only diagnosed after an autopsy was carried out following his death, and Schneider has now joined forces with the American Brain Foundation to "cure all brain disease", reports femalefirst.co.uk.. "The biggest battle of his life was against Lewy Body Disease. This terrifying disease attacks the brain. No matter how many doctors we saw, symptoms we chased, or tests we ran, it was only in autopsy that I learned we had unknowingly been battling a deadly disease. A disease for which there is no cure," Schneider said while accepting the 2016 Angel Harvey Heart of a Patriot Award from the USO on Williams behalf here.. "The devastation on Robins brain from the Lewy bodies, was one of the worst cases medical professionals have ever seen. Yet throughout all of this, his heart remained strong," she said..

Most loss-of-function diseases are caused by aberrant folding of important proteins. These proteins often misfold due to inherited mutations. The rare disease marble brain disease (MBD) also known as carbonic anhydrase II deficiency syndrome (CADS) can manifest in carriers of point mutations in the human carbonic anhydrase II (HCA II) gene. We have over the past 10-15 years studied the folding, misfolding and aggregation of the enzyme human carbonic anhydrase II. In summary our HCA II folding studies have shown that the protein folds via an intermediate of molten-globule type, which lacks enzyme activity and the molten globule state of HCA II is prone to aggregation. One mutation associated with MBD entails the His107Tyr (H107Y) substitution. We have demonstrated that the H107Y mutation is a remarkably destabilizing mutation influencing the folding behavior of HCA II. A mutational survey of position H107 and a neighboring conserved position E117 has been performed entailing ...
Non-enzymatic protein modifications occur inevitably in all living systems. Products of such modifications accumulate during aging of cells and organisms and may contribute to their age-related functional deterioration. This review presents the formation of irreversible protein modifications such as carbonylation, nitration and chlorination, modifications by 4-hydroxynonenal, removal of modified proteins and accumulation of these protein modifications during aging of humans and model organisms, and their enhanced accumulation in age-related brain diseases.
The news that former Patriots player Junior Seau suffered from degenerative brain disease when he committed suicide last year should be a warning to players and coaches across the National Football League - keep players off the field for at least a game after concussions, while the league probes ways to reduce the level of head trauma players face in their careers. Seau, a pro linebacker for 20 years, was the unmistakable victim of too many hits to the head.

Autosomal dominant porencephaly type I is a rare type of porencephaly that causes cysts to grow on the brain and damage to small blood vessels, which can lead to cognitive impairment, migraines, seizures, and hemiplegia or hemiparesis. Different people are affected very differently by this disease. The main manifestation is fluid-filled cysts that grow on the brain and can cause damage that varies depending on their location and severity. Symptoms may manifest early in infancy, or may manifest as late as adulthood. Symptoms associated with autosomal dominant porencephaly type I include migraines, hemiplegia or hemiparesis, seizures, cognitive impairment, strokes, dystonia, speech disorders, involuntary muscle spasms, visual field defects, and hydrocephalus. Autosomal dominant porencephaly type I is caused by mutations in a gene called COL4A1, located at 13q34 (band 34 on the long arm of chromosome 13). These mutations are ...
Polymicrogyria (PMG) and periventricular nodular heterotopia (PNH) are two developmental brain malformations that have been described independently in multiple syndromes. Clinically, they present with epilepsy and developmental handicaps in both children and adults. Here we describe their occurrence together as the two major findings in a group of at least three cortical malformation syndromes. We identified 30 patients as having both PNH and PMG on brain imaging, reviewed clinical data and brain imaging studies (or neuropathology summary) for all, and performed mutation analysis of FLNA in nine patients. The group was divided into three subtypes based on brain imaging findings. The frontal-perisylvian PNH-PMG subtype included eight patients (seven males and one female) between 2 days and 10 years of age. It was characterized by PNH lining the lateral body and frontal horns of the lateral ventricles and by ...
PRES is also known as acute hypertensive encephalopathy or reversible posterior leukoencephalopathy.. The term PRES can be a misnomer as the syndrome can involve or extend beyond the posterior cerebrum. Furthermore, although most cases involve a resolution of changes with the treatment of the precipitating cause and clinical recovery some patients can progress to develop permanent cerebral injury and be left with residual neurological defects.. It should not be confused with chronic hypertensive encephalopathy, also known as hypertensive microangiopathy, which results in microhemorrhages in the basal ganglia, pons, and cerebellum. ...
Estrogens are neuroprotective factors for brain diseases, including hypertensive encephalopathy. In particular, the hippocampus is highly damaged by high blood pressure, with several hippocampus functions being altered in humans and animal models of hypertension. Working with a genetic model of primary hypertension, the spontaneously hypertensive rat (SHR), we have shown that SHR present decreased dentate gyrus neurogenesis, astrogliosis, low expression of brain derived neurotrophic factor (BDNF), decreased number of neurons in the hilus of the dentate gyrus, increased basal levels of the estrogen-synthesizing enzyme aromatase, and atrophic dendritic arbor with low spine density in the CA1 region compared to normotensive Wistar Kyoto (WKY) ratsl. Changes also occur in the hypothalamus of SHR, with increased expression of the hypertensinogenic peptide arginine vasopressin (AVP) and its V1b receptor. Following chronic ...
Periventricular nodular heterotopia (PNH) is a disorder of cortical development [1]. PNH is a term used to describe the collections of neurons lining the lateral ventricles that have failed to migrate normally to form the cerebral cortex [1]. It is a clinically and genetically heterogeneous group of disorders [2]. Mutations in the filamin A gene (FLNA) result in an X-linked dominant form of this disorder [3]. Mutations in FLNA leading to protein truncation are the predominant cause of the PNH phenotype [2, 4]. Most affected females present with seizures and normal to mildly impaired cognitive function [2, 5]. FLNA-associated PNH may also be associated with other cerebral malformations as well as extra-cerebral features [6]. The condition typically results in prenatal lethality or a more severe phenotype in males although paternal transmission has been documented in the literature [2, 7-9].. Mutations in FLNA are associated with a wide spectrum of disorders including the otopalatodigital ...
Sarcoidosis is an idiopathic multisystem granulomatous disorder of unknown cause. Nervous system involvement (central and/or peripheral) is uncommon, developing in 5%-10%. The presenting symptoms are variable, reflecting the level of involvement, and frequently fluctuate and progress. Diagnosing neurosarcoidosis in people with previously confirmed systemic disease may be relatively straightforward, but diagnosing primary neurosarcoidosis is challenging. Managing neurosarcoidosis is primarily consensus based; corticosteroid is its mainstay, alongside corticosteroid-sparing agents and emerging novel therapies. We describe a 39-year-old woman who presented with cranial neuropathy. Serial imaging, cerebrospinal fluid sampling and tissue biopsy gave a diagnosis of probable neurosarcoidosis. Her clinical course was complicated by intracerebral haemorrhage following intravenous corticosteroids for neurological relapse. This is a very rare complication of neurosarcoidosis; we discuss its possible causes ...
Choroid plexus cyst. Ultrasound scan of a foetus brain with a choroid plexus cyst (CPC). The choroid plexus is a layer of cells and blood vessels at the centre of the foetal brain. It produces a fluid, called cerebrospinal fluid, that flows around the brain and provides a protective cushion for it against impacts. CPCs in foetuses are temporary bubbles of trapped fluid that are usually gone by the 32nd week of pregnancy. They are classed as markers for underlying chromosome abnormalities in the foetus. Ultrasound scanning is a diagnostic technique that sends high-frequency sound waves into the body via a transducer. The returning echoes are recorded and used to build an image of an internal structure. - Stock Image M130/1007

A pilot case-control study was done to collect data on whether susceptibility to newborn encephalopathy and neonatal seizures is influenced by the degree of maternal-fetal sharing of HLA antigens. Cases included 13 infants with moderate or severe newborn encephalopathy and seven infants with neonatal seizures but no other signs of encephalopathy. Controls were neurologically normal infants matched to cases by date of birth, sex, race, and payment status. Infants and their mothers were typed for HLA-A, -B, -DR, and -DQ antigens. The observed frequency of sharing of maternal antigens was greater than expected (ie, 0.5) for cases compared to controls at the HLA-B, -DR, and -DQ loci but not for HLA-A. The risk of neurologic problems in the neonatal period was increased 6.3 times when there was more than one match at the HLA-DR or -DQ locus. Placental abnormalities were noted at delivery only among cases, and the mean placental weight in cases was 598 g versus 695 g in controls. Further studies with sample
Unless you are newly diagnosed, chances are you have heard a lot about the connection between eating gluten (a protein found in wheat, barley, rye, oats) and auto immune diseases like Hashimotos.. You also have probably heard from your doctor, online nutritionists, and many mainstream media outlets and late night talk show hosts saying it is a lot of BS, and that you actually NEED gluten to be healthy.. So Who Is Right? And also, just how strict do I really need to be? Cant I have a little cheat? What if I dont have any gut symptoms?. To find out the answer, I searched through research articles on PubMed. I already knew my stance on the issue, but wanted to make sure there was current research that supported it.. The September 2015 edition of the journal Gastroenterology found high "proportions of patients with NCWS or CD develop autoimmune disorders, are ANA positive, and showed DQ2/DQ8 haplotypes". (note- NCWS is non-Celiac wheat sensitivity.). In the March 2015 journal Cerebellum, gluten ...

Abstract A space-occupying lesion 3.5 by 2.0 cm in size caused by Capillaria infection was revealed ultrasonographically in segment 6 (S6) of the liver of a 32-year-old woman from Okinawa, Japan, who was hospitalized with a complaint of pain in the right upper quadrant. Laboratory examination showed leukocytosis of 10,400/mm3 with 22% eosinophils and slight impairment of liver function. The tumor was removed surgically and found to be a necrotic granuloma with eosinophilic infiltration formed around a degenerated nematode. The causative agent was presumed to be Capillaria hepatica based on the morphology of the bacillary bands and stichosome observed in the sectioned worm and in the fragments of worm recovered by dissecting the tumor tissue that was embedded in paraffin.
Mucolipidosis type IV (MLIV) is a lysosomal storage disease caused by mutations in the MCOLN1 gene, which encodes the lysosomal transient receptor potential ion channel mucolipin-1 (TRPML1). MLIV causes impaired motor and cognitive development, progressive loss of vision and gastric achlorhydria. How loss of TRPML1 leads to severe psychomotor retardation is currently unknown and there is no therapy for MLIV. White matter abnormalities and a hypoplastic corpus callosum are the major hallmarks of MLIV brain pathology. Here we report that loss of TRPML1 in mice results in developmental aberrations of brain myelination due to deficient maturation and loss of oligodendrocytes. Defective myelination is evident in Mcoln1−/− mice at post-natal day 10, an active stage of post-natal myelination in the mouse brain. Expression of mature oligodendrocyte markers is reduced in Mcoln1−/− mice at post-natal day 10 and remains lower throughout the course of disease. We ...
Elia et al. described the clinical and electroencephalographic features of three boys with CDKL5 mutations. [1] They concluded that, similarly to girls with this mutation, "epilepsy appears to be polymorphous, with myoclonic, tonic, and partial seizures or spasms" and that "interictal EEG pattern is characterized by focal, multifocal, diffuse pseudoperiodic epileptiform activity." Elia considered these clinical and electroencephalographic observations similar to other findings. [2-3] However, the EEG pattern reported by Elia et al. was actually first described by us. [4] We described the seizures of three CDKL5 patients as starting as complex partial seizures or tonic spasms and then becoming complex partial, tonic, and unexpectedly, myoclonic seizures of such prominence to justify the definition of "myoclonic encephalopathy." In this stage, the EEG showed an "intercritical pattern with pseudoperiodic, diffuse sharp waves or pseudoperiodic, diffuse spike and polyspike and wave discharges and ...
Vegetative state refers to the neurocognitive status of individuals with severe brain damage, in whom physiologic functions (sleep-wake cycles, autonomic control, and breathing) persist, but awareness (including all cognitive function and emotion) is abolished.
BACKGROUND/AIMS: Previous studies have suggested that autophagy is activated in distinct cerebrovascular diseases, including stroke. However, the underlying regulatory mechanism of autophagy under stroke remained elusive. Accumulating evidence indicates that dysfunctions of microRNAs (miRNAs) are involved in the pathological process of stroke. Therefore, this study was taken to identify the effect of microRNA-9a-5p (miR-9a-5p) on autophagy in rats following stroke. METHODS: The rat model of focal cerebral ischemia was established by middle cerebral artery occlusion (MCAO) surgery; The neurological outcomes were defined by neurological evaluation and infarct volume; The western blotting and immunofluorescence assays were used to detected the protein levels of microtubule-associated protein 1 light chain 3 (LC3) and autophagy related 5 (ATG5); The mRNA level of miR-9a-5p, LC3 and ATG5 were quantified by real-time RT-PCR; The luciferase activities of ATG5 and miR-9a-5p was detected by ...

President Obama awarded Prusiner the National Medal of Science in 2010 to recognize the importance of his work. Unfortunately, this groundbreaking research is being ignored. This negligence is fueling a public health disaster around the world, as critical pathways are being ignored and mismanaged. The mismanagement also is contributing to the global surge in autism.. In June 2012, Prusiner confirmed that Alzheimers, Parkinsons, Huntingtons and even ALS are prion diseases similar, if not identical, to Creutzfeldt-Jakob disease. The primary difference being which part of the brain the disease attacks first. The other variable is that there are now an unknown number of prion mutations. Mutations of these deadly prions are the common denominator between all forms of TSEs. Most of the carnage is being swept under the rug as the problem escalates.. "There is now real evidence of the potential transmissibility of Alzheimers," says Thomas Wiesniewski M.D. a prion and Alzheimers ...
Researchers have uncovered how infectious proteins called prions use specialised cells (labelled green) to cross the lining of the gut and establish infection before spreading to the brain where they cause disease. Copyright: Neil Mabbott, The Roslin Institute. The research also suggests that the presence of other infections in the gut such as Salmonella may increase the chances of prions causing infection.. Prion diseases - also known as transmissible spongiform encephalopathies (TSEs) - are infectious brain conditions that affect people and animals. They are caused by abnormally shaped proteins which can be passed on by eating contaminated meat.. Previous research revealed that the proteins must first build up in specialised structures in the lining of the small intestine called Peyers patches before they are able to spread to the brain.. The diseases include vCJD in people, BSE in cows, scrapie in sheep and chronic ...

Thirty-five cases of biopsy-proven sarcoidosis with neurologic manifestations are reported. Neurosarcoidosis was the presenting symptom in 31% of cases and the only clinical manifestation in 17%. Mean follow-up time was 48 months. Central nervous system involvement was observed in 37% and meningitis in 40% of patients. Other manifestations were cranial nerve palsies (37%), peripheral neuropathy (40%), and myopathy (26%). Multiple neurologic manifestations were present in 51% of cases. All but 4 were treated with corticosteroids. Another immunosuppressive agent or cerebral irradiation was added in 6 and 2 patients, respectively. Complete recovery was observed in 46%, improvement in 46%, 4% remained stable, and 4% worsened. There were no deaths. We advocate treating neurosarcoidosis with corticosteroids as early as possible. If the patients condition worsens, additional immunosuppressive agents or cerebral irradiation is warranted.
Thiamine transporter-2 deficiency is a recessive disease caused by mutations in the SLC19A3 gene. Patients manifest acute episodes of encephalopathy; symmetric lesions in the cortex, basal ganglia, thalami or periaqueductal gray matter, and a dramatic response to biotin or thiamine. We report a 30-day-old patient with mutations in the SLC19A3 gene who presented with acute encephalopathy and increased level of lactate in the blood (8.6 mmol/L) and cerebrospinal fluid (7.12 mmol/L), a high excretion of α-ketoglutarate in the urine, and increased concentrations of the branched-chain amino acids leucine and isoleucine in the plasma. MRI detected bilateral and symmetric cortico-subcortical lesions involving the perirolandic area, bilateral putamina, and medial thalami. Some lesions showed low apparent diffusion coefficient values suggesting an acute evolution; others had high values likely to be subacute or chronic, most likely related to the perinatal period. After treatment ...
