beta-Spectrin Sao PauloII, a novel frameshift mutation of the beta-spectrin gene associated with hereditary spherocytosis and instability of the mutant mRNA. (1/24)

Hereditary spherocytosis (HS) is a common inherited anemia characterized by the presence of spherocytic red cells. Defects in several membrane protein genes have been involved in the pathogenesis of HS. beta-Spectrin-related HS seems to be common. We report here a new mutation in the beta-spectrin gene coding region in a patient with hereditary spherocytosis. The patient presented acanthocytosis and spectrin deficiency and, at the DNA level, a novel frameshift mutation leading to HS, i.e., a C deletion at codon 1392 (beta-spectrin Sao PauloII), exon 20. The mRNA encoding beta-spectrin Sao PauloII was very unstable and the mutant protein was not detected in the membrane or in other cellular compartments. It is interesting to note that frameshift mutations of the beta-spectrin gene at the 3' end allow the insertion of the mutant protein in the red cell membrane, leading to a defect in the auto-association of the spectrin dimers and consequent elliptocytosis. On the other hand, beta-spectrin Sao PauloII protein was absent in the red cell membrane, leading to spectrin deficiency, HS and the presence of acanthocytes.  (+info)

Acanthocytes of Stropharia rugosoannulata function as a nematode-attacking device. (2/24)

Efficient killing of nematodes by Stropharia rugosoannulata Farlow ex Murrill cultures was observed. This fungus showed the ability to immobilize the free-living nematode Panagrellus redivivus Goodey within minutes and to immobilize the pine wilt nematode Bursaphelenchus xylophilus (Steiner & Buhrer) Nickle within hours on agar plates. Moreover, P. redivivus worms were completely degraded by the fungus within 24 to 48 h. The cultures of S. rugosoannulata studied shared the characteristic of abundantly producing cells with finger-like projections called acanthocytes. We showed that the nematode-attacking activity of this fungus is carried out by these spiny acanthocytes and that mechanical force is an important factor in the process. Furthermore, the growth and nematode-attacking activity of the fungus in soil were also determined, and our results suggest that acanthocytes are functional in soil.  (+info)

Autopsy case of Dubin-Johnson syndrome with pneumonia and abetalipoproteinemia-like lipid profile. (3/24)

We report the autopsy of a 79-year-old Japanese woman with Dubin-Johnson syndrome accompanied by pneumonia, an abetalipoproteinemia-like lipid profile and acanthocytosis. On admission, physical examination of the patient revealed malnutrition. Blood tests revealed marked inflammatory changes and mild liver dysfunction. Chest X-ray indicated bilateral pneumonia. Total cholesterol, low-density lipoprotein (LDL) cholesterol and triglyceride levels were 89 mg/dL, 5 mg/dL and 6 mg/dL, respectively. Peripheral blood smears revealed numerous acanthocytes. Despite the administration of antibiotics and nutritional support, the patient died. Autopsy revealed a black liver, atrophy of fat tissue on the mesentery, and pneumonia with bilateral pleural effusion. We believe that the abetalipoproteinemia-like lipid profiles in this case were caused by malnutrition and the inflammatory changes rather than the direct effects of Dubin-Johnson syndrome. We base this conclusion on the following three findings: 1) the patient's lipid profile before hospitalization was in the normal range, 2) her serum LDL cholesterol and triglyceride levels gradually increased after nutritional support began, and 3) blood tests revealed marked inflammatory changes (C-reactive protein 9.0 mg/dL; interleukin-6 16.4 pg/mL). This case provides important information that enhances our understanding of lipid metabolism under conditions of malnutrition and inflammation.  (+info)

Insights into extensive deletions around the XK locus associated with McLeod phenotype and characterization of two novel cases. (4/24)

The McLeod phenotype is derived from various forms of XK gene defects that result in the absence of XK protein, and is defined hematologically by the absence of Kx antigen, weakening of Kell system antigens, and red cell acanthocytosis. Individuals with the McLeod phenotype usually develop late-onset neuromuscular abnormalities known as the McLeod syndrome (MLS). MLS is an X-linked multi-system disorder caused by absence of XK alone, or when the disorder is caused by large deletions, it may be accompanied with Duchenne muscular dystrophy (DMD), chronic granulomatous disease (CYBB), retinitis pigmentosa (RPGR), and ornithine transcarbamylase deficiency (OTC). XK defects derived from a large deletion at the XK locus (Xp21.1) have not been characterized at the molecular level. In this study, the deletion breakpoints of two novel cases of McLeod phenotype with extensive deletions are reported. Case 1 has greater than 1.12 million base-pairs (mb) deletion around the XK locus with 7 genes affected. Case 2 has greater than 5.65 mb deletion from TCTE1L to DMD encompassing 20 genes. Phylogenetic analyses demonstrated that DMD, XK and CYBB have close paralogs, some of which may partially substitute for the functions of their counterparts. The loci around XK are highly conserved from fish to human; however, the disorders are probably specific to mammals, and may coincide with the translocation of the loci to the X chromosome after the speciation in birds. The non-synonymous to synonymous nucleotide substitution rate ratio (omega=dN/dS) in these genes was examined. CYBB and RPGR show evidence of positive selection, whereas DMD, XK and OTC are subject to selective constraint.  (+info)

Chorea-acanthocytosis (ChAc, also called Choreoacanthocytosis), is a rare hereditary disease caused by a mutation of the gene that directs structural proteins in red blood cells. It belongs to a group of four diseases characterized under the name Neuroacanthocytosis. When a patients blood is viewed under a microscope, some of the red blood cells appear thorny. These thorny cells are called acanthocytes. Other effects of the disease may include epilepsy, behaviour changes, muscle degeneration, and neuronal degradation similar to Huntingtons Disease. The average age of onset of symptoms is 35 years. The disease is incurable and inevitably leads to premature death. Some more information about Chorea-acanthocytosis is that it is a very complex autosomal recessive adult-onset neurodegenerative disorder. It often shows itself as a mixed movement disorder, in which chorea, tics, dystonia and even parkinsonism may appear as a symptom. This disease is also characterized by the presence of a few ...
Spur cell anaemia (acanthocytosis), a rare acquired haemolytic anaemia observed mainly in the end stages of alcoholic cirrhosis, is characterised by an increased ratio of free cholesterol to phospholipid in the erythrocyte membranes that results in multispiculated erythrocytes (acanthocytes). These acanthocytes undergo rapid splenic destruction and consequently have a shortened survival. Recent studies have indicated that alcoholic iron overload may be associated with spur cell anaemia rather than hereditary haemochromatosis. Patients usually need frequent blood transfusions and the prognosis is extremely poor. Liver transplantation, which improves hepatic function and resolves spur cell anaemia, has been the most effective treatment. Our patient did not choose liver transplantation. She had a poor response to conservative treatment with multiple blood transfusions and died of liver failure seven months later. ...

Zieves syndrome is an acute metabolic condition that can occur during withdrawal from prolonged alcohol abuse. It is defined by hemolytic anemia (with spur cells and acanthocytes), hyperlipoproteinaemia (excessive blood lipoprotein), jaundice (elevation of unconjugated bilirubin), and abdominal pain. The underlying cause is liver delipidization. This is distinct from alcoholic hepatitis which, however, may present simultaneously or develop later. Diagnosis of Zieves syndrome should be considered in alcoholic (especially after an episode of binge drinking) with an elevation of unconjugated bilirubin and without obvious signs of gastrointestinal bleeding. The proposed mechanism of the characteristic haemolytic anaemia in Zieves syndrome is due to alteration of the red cell metabolism, namely pyruvate kinase instability leaving them susceptible to circulating hemolysin such as lysolecithin. Changes in membrane lipid compositions such as increased cholesterol and polyunsaturated fatty acid (PUFA) ...
orange arrow). Acanthocytes (red arrow) signifies acute renal injury. Further workup showed the following: total bilirubin, 3.2 mg/dL (reference range, 0.1-1.2); indirect bilirubin, 2.2 mg/dL (0.1-0.8); serum haptoglobin, ,0.01 g/L (0.3-2); serum creatinine, 2.6 mg/dL (0.8-1.3); and glucose-6-phosphate dehydrogenase (G6PD) level, 5.1 U/gHb (6.7-14.3). G6PD level measured after 8 weeks was 0.2 U/gHb He had no similar episode in the past. Urinary pseudomonas isolates was the likely cause of the fever. According to the PBS findings and low G6PD levels, we made a diagnosis of G6PD deficiency, which is an X-linked hereditary disease characterized by low levels of G6PD, a metabolic enzyme involved in the pentose phosphate pathway. Antimalarials usually induce acute hemolysis in G6PD-deficient individuals. Late presentation is not uncommon, where peripheral smear can be useful in diagnosis without medical or family history. ...
Acanthocyte, in human biology and medicine, refers to a form of red blood cells with spikes on it.

XKR5 belongs to the XK family. XK is a protein found on human red blood cells and other tissues which is responsible for the Kx antigen which helps determine a persons blood type. The Kx antigen plays a role in matching blood for blood transfusions. Absence of XK protein leads to McLeod syndrome, a multi-system disorder characterized by hemolytic anemia, myopathy, acanthocytosis, and chorea. XK is located on the X chromosome and absence of the XK protein is an X-linked disease. XK is a membrane transport protein of unknown action.The XK locus is inactivated by lyonization. The precursor missing in McLeods red cells is called Kx. The X-linked locus determining this substance is called XK.
Chorea-acanthocytosis (ChAc) is a severe, neurodegenerative disorder that shares clinical features with Huntingtons disease and McLeod syndrome.

Chorea-Acanthocytosis (ChAc) is a devastating, little understood, and currently untreatable neurodegenerative disease caused by VPS13A mutations. Based on our recent demonstration that accumulation of activated Lyn tyrosine kinase is a key pathophysiological event in human ChAc cells, we took advantage of Vps13a−/− mice, which phenocopied human ChAc. Using proteomic approach, we found accumulation of active Lyn, γ-synuclein and phospho-tau proteins in Vps13a−/− basal ganglia secondary to impaired autophagy leading to neuroinflammation. Mice double knockout Vps13a−/− Lyn−/− showed normalization of red cell morphology and improvement of autophagy in basal ganglia. We then in vivo tested pharmacologic inhibitors of Lyn: dasatinib and nilotinib. Dasatinib failed to cross the mouse brain blood barrier (BBB), but the more specific Lyn kinase inhibitor nilotinib, crosses the BBB. Nilotinib ameliorates both Vps13a−/− hematological and neurological phenotypes, improving autophagy and

The term acanthocytosis is derived from the Greek for thorn and is used to describe a peculiar spiky appearance of erythrocytes. Acanthocytosis is found to be associated with at least three hereditary neurological disorders that are generally referred to as neuroacanthocytosis. Abetalipoproteinaemia is an autosomal recessive condition, characterised by absence of serum apolipoprotein B containing lipoproteins leading to fat intolerance and fat-soluble vitamin deficiency. This results in a progressive spinocerebellar ataxia with peripheral neuropathy and retinitis pigmentosa. Chorea-acanthocytosis is also an autosomal recessive condition and is characterised by chorea, orofaciolingual dyskinesia, dysphagia, dysarthria, areflexia, seizures and dementia. Some of its features, including choreic movements, peripheral neuropathy with areflexia, elevated serum creatine kinase levels and myopathy are shared by another form of neuroacanthocytosis, McLeod syndrome. Patients affected by this X-linked disorder
The symptoms and severity of neuroacanthocytosis can vary from one person to another, even among individuals with the same subtype or among individuals within the same family. It is important to note that affected individuals may not have all of the symptoms discussed below. Affected individuals should talk to their physician and medical team about their specific case, associated symptoms and overall prognosis.. The age of onset and progression of these disorders also varies. Chorea-acanthocytosis and McLeod syndrome progress slowly over many years or decades during adulthood. In many cases, PKAN presents in childhood and rapidly progresses within 10 years. These disorders can all potentially progress to cause life-threatening complications.. All of these disorders share certain findings including abnormal involuntary movements, cognitive deterioration and acanthocytosis. The most common movement disorder associated with neuroacanthocytosis is chorea, which is characterized by rapid, ...
Red blood cells are disc shaped cells that carry oxygen in the blood. There are various disorders that can lead to an abnormal shape of these cells. The term acanthocytosis describes the presence of distorted red blood cells (acanthocytes) in the blood. The cells become denser and irregularly shaped with spiculated (sharp spur-like) protrusions. The normal shape of red blood cells are determined by certain proteins in its cell membrane. When there are certain defects or deficiencies of these proteins, abnormal shapes of the red blood cells are seen. However, these proteins are also common to other types of cells in the body like the nerve cells and brain tissue. This collectively leads to certain conditions marked by abnormalities of both the red blood cells and disturbances in brain function.. ...

The differential diagnosis of hematuria is often divided into microscopic hematuria or macroscopic hematuria. Microscopic hematuria is present when microscopic inspection of at least 2 properly collected urine specimens show > 3 RBCs per high-powered field (hpf). Macroscopic hematuria is red or brown urine, sometimes with blood clots. However, there is considerable overlap in the causes of microscopic and macroscopic hematuria, and it may be more practical to first consider whether the hematuria is glomerular in origin. Pivotal points that help distinguish glomerular hematuria from nonglomerular hematuria include dysmorphic RBCs (acanthocytes), red cell casts, new or acutely worsening hypertension or proteinuria, and increased creatinine. While these abnormalities may also be seen in some of the interstitial and vascular causes of hematuria, they will not be found when hematuria is caused by a renal structural abnormality or an abnormality distal to the kidneys. Visible blood clots, which are ...
Neuroacanthocytosis encompasses a group of genetically heterogenous disorders characterized by neurologic signs and symptoms associated with acanthocytosis, an abnormality of red blood cells. Neurologic problems usually consist of either movement disorders or ataxia, personality changes, cognitive deterioration, axonal neuropathy, and seizures.
In the McLeod phenotype, acanthocytosis occurs (Figure 8.10), together with decreased expression of the Kell antigen. The defective gene is on the X chromosome, Xp21, close to genes for Duchenne muscular dystrophy and retinitis pigmentosa, conditions with which the phenotype has been linked.

Chorea-acanthocytosis (ChAc) is a rare neurodegenerative disease associated with mutations in the human VPS13A gene. The mechanism of ChAc pathogenesis is unclear. A simple yeast model was used to investigate the function of the single yeast VSP13 orthologue, Vps13. Vps13, like human VPS13A, is involved in vesicular protein transport, actin cytoskeleton organisation and phospholipid metabolism. A newly identified phenotype of the vps13Δ mutant, sodium dodecyl sulphate (SDS) hypersensitivity, was used to screen a yeast genomic library for multicopy suppressors. A fragment of the MYO3 gene, encoding Myo3-N (the N-terminal part of myosin, a protein involved in the actin cytoskeleton and in endocytosis), was isolated. Myo3-N protein contains a motor head domain and a linker. The linker contains IQ motifs that mediate the binding of calmodulin, a negative regulator of myosin function. Amino acid substitutions that disrupt the interaction of Myo3-N with calmodulin resulted in the loss of vps13Δ ...

Conclusions Causes of death in ChAc and McLeod syndrome are similar to those in Huntingtons disease, with additional risks due to the presence of seizures and cardiac disease. Suicidality was seen in 10% of patients with ChAc. Sudden unexplained deaths were frequently seeen. In the absence of disease-modifying agents, disease management should focus upon treating symptoms which may contribute to morbidity and mortality. ...

McLeod neuroacanthocytosis syndrome is primarily a neurological disorder that occurs almost exclusively in boys and men. This disorder affects movement in many parts of the body. People with McLeod neuroacanthocytosis syndrome also have abnormal star-shaped red blood cells (acanthocytosis). This condition is one of a group of disorders called neuroacanthocytoses that involve neurological problems and abnormal red blood cells.. McLeod neuroacanthocytosis syndrome affects the brain and spinal cord (central nervous system). Affected individuals have involuntary movements, including jerking motions (chorea), particularly of the arms and legs, and muscle tensing (dystonia) in the face and throat, which can cause grimacing and vocal tics (such as grunting and clicking noises).

The effect of oxytocin on phosphoinositide metabolism as well as on membrane protein phosphorylation in myometrial tissue was studied. Oxytocin enhanced the 32P incorporation into phospholipids in myometrial tissue. The effect of oxytocin on phosphoinositide metabolism was also detected in plasma membrane of 20 days pregnant rats. Phosphorylated membrane lipids have been analysed and phosphatidylinositol 4, 5-bisphosphate proved to be the main reaction product. Oxytocin enhanced the 32P incorporation into phospholipids measured in the first 30 sec then the labeling decreased more rapidly then in case of the control. The effect of oxytocin proved to be concentration dependent. The protein phosphorylation was also influenced by oxytocin. However the amount of alkylphosphate formed depended on the presence or absence of Ca2+, Ca2+-calmodulin and cyclic AMP, oxytocin influenced the protein phosphorylation in the presence of Ca2+-calmodulin only.

Rodney McLeod was credited with a 53-yard fumble return for a touchdown, giving the Eagles a 21-9 lead over the Cowboys with 5:18 remaining. But the play was not without controversy. It appeared Vinny Curry recovered a Ben DiNucci fumble and was down by contact, touched by Connor Williams, before Williams ripped the ball out. [more]

One thing we always try to do while traveling is to stay in B and Bs or now use Air B and B and farm stays its a delightful way to meet locals and learn about local food culture. One such place was Arco di pepe b&b in Trani, the hosts were so friendly and with the help of google translate on their phone we were able to communicate somewhat. They have a cute little farmstead, with a couple of goats, a horse, a few chickens and a garden, with olive and fruit trees, flowers and vegetables. They even make their own extra virgin olive oil. See below for a fun clip of them chatting to my parents as they were preparing zucchini stems to make with pasta. Did you know that these were edible?

Cílem navrhovaného projektu je analýza genetických faktorů podílejících se na regulaci pro-/antioxidační rovnováhy v patogenezi alergických respiračních nemocí. Pomocí technologie microarrays hodláme v buněčném materiálu z bronchoalveolárních laváží astmatiků a kontrolních jedinců identifikovat tzv. geny oxidačního stresu, které se podílejí na spuštění a udržování zánětu v dýchacích cestách. Geny, jejichž exprese se budou významně lišit mezi pacienty a kontrolami, budeme považovat za kandidátní a budme u nich de novo analyzovat genetickou variabilitu. Budeme analyzovat vztah mezi klinickým fenotypem a substitucemi v přepisovaných i regulačních oblastech jak známých funkčních kandidátních genů, tak i genů nově zjištěných na základě rozdílné exprese. Analýza genet. variant bude prováděna metodami založenými na PCR v asociačních studiích tzv. případů-kontrol a dále potvrzena studiemi tzv. příbuzných ...

The term "σήψις" (sepsis) was introduced by Hippocrates in the fourth century BC, and it meant the process of decay or decomposition of organic matter.[103][104][105] In the eleventh century, Avicenna used the term "blood rot" for diseases linked to severe purulent process. Though severe systemic toxicity had already been observed, it was only in the 19th century that the specific term - sepsis - was used for this condition. The terms "septicemia", also spelled "septicaemia", and "blood poisoning" referred to the microorganisms or their toxins in the blood. The International Statistical Classification of Diseases and Related Health Problems (ICD) version 9, which was in use in the US until 2013, used the term septicemia with numerous modifiers for different diagnoses, such as "Streptococcal septicemia".[106] All those diagnoses have been converted to sepsis, again with modifiers, in ICD-10, such as "Sepsis due to streptococcus".[106] The current terms are dependent on the microorganism that ...
