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.

While postsynaptic alpha-2 receptors play a traditional role in mediating the effects of ADRENERGIC AGONISTS, the subset of alpha-2 receptors found on presynaptic membranes signal the feedback inhibition of NEUROTRANSMITTER release.
General or unspecified injuries to the soft tissue or bony portions of the face.
Severe or complete loss of facial muscle motor function. This condition may result from central or peripheral lesions. Damage to CNS motor pathways from the cerebral cortex to the facial nuclei in the pons leads to facial weakness that generally spares the forehead muscles. FACIAL NERVE DISEASES generally results in generalized hemifacial weakness. NEUROMUSCULAR JUNCTION DISEASES and MUSCULAR DISEASES may also cause facial paralysis or paresis.
Pathologic changes that occur in the axon and cell body of a neuron proximal to an axonal lesion. The process is characterized by central chromatolysis which features flattening and displacement of the nucleus, loss of Nissl bodies, and cellular edema. Central chromatolysis primarily occurs in lower motor neurons.
A pathological process characterized by injury or destruction of tissues caused by a variety of cytologic and chemical reactions. It is usually manifested by typical signs of pain, heat, redness, swelling, and loss of function.
Either of two extremities of four-footed non-primate land animals. It usually consists of a FEMUR; TIBIA; and FIBULA; tarsals; METATARSALS; and TOES. (From Storer et al., General Zoology, 6th ed, p73)
The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago. (From Walker's Mammals of the World, 6th ed, p801)
General or unspecified injuries to the heart.
The cochlear part of the 8th cranial nerve (VESTIBULOCOCHLEAR NERVE). The cochlear nerve fibers originate from neurons of the SPIRAL GANGLION and project peripherally to cochlear hair cells and centrally to the cochlear nuclei (COCHLEAR NUCLEUS) of the BRAIN STEM. They mediate the sense of hearing.
Identification of proteins or peptides that have been electrophoretically separated by blot transferring from the electrophoresis gel to strips of nitrocellulose paper, followed by labeling with antibody probes.
Cell surface receptors that bind NERVE GROWTH FACTOR; (NGF) and a NGF-related family of neurotrophic factors that includes neurotrophins, BRAIN-DERIVED NEUROTROPHIC FACTOR and CILIARY NEUROTROPHIC FACTOR.
General or unspecified injuries involving the fingers.
The major nerves supplying sympathetic innervation to the abdomen. The greater, lesser, and lowest (or smallest) splanchnic nerves are formed by preganglionic fibers from the spinal cord which pass through the paravertebral ganglia and then to the celiac ganglia and plexuses. The lumbar splanchnic nerves carry fibers which pass through the lumbar paravertebral ganglia to the mesenteric and hypogastric ganglia.
The 9th cranial nerve. The glossopharyngeal nerve is a mixed motor and sensory nerve; it conveys somatic and autonomic efferents as well as general, special, and visceral afferents. Among the connections are motor fibers to the stylopharyngeus muscle, parasympathetic fibers to the parotid glands, general and taste afferents from the posterior third of the tongue, the nasopharynx, and the palate, and afferents from baroreceptors and CHEMORECEPTOR CELLS of the carotid sinus.
An activating transcription factor that plays a key role in cellular responses to GENOTOXIC STRESS and OXIDATIVE STRESS.
The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.
A variation of the PCR technique in which cDNA is made from RNA via reverse transcription. The resultant cDNA is then amplified using standard PCR protocols.
Damage to the MYOCARDIUM resulting from MYOCARDIAL REPERFUSION (restoration of blood flow to ischemic areas of the HEART.) Reperfusion takes place when there is spontaneous thrombolysis, THROMBOLYTIC THERAPY, collateral flow from other coronary vascular beds, or reversal of vasospasm.
Traumatic injuries to the cranium where the integrity of the skull is not compromised and no bone fragments or other objects penetrate the skull and dura mater. This frequently results in mechanical injury being transmitted to intracranial structures which may produce traumatic brain injuries, hemorrhage, or cranial nerve injury. (From Rowland, Merritt's Textbook of Neurology, 9th ed, p417)
Injuries of tissue other than bone. The concept is usually general and does not customarily refer to internal organs or viscera. It is meaningful with reference to regions or organs where soft tissue (muscle, fat, skin) should be differentiated from bones or bone tissue, as "soft tissue injuries of the hand".
Diseases of the trigeminal nerve or its nuclei, which are located in the pons and medulla. The nerve is composed of three divisions: ophthalmic, maxillary, and mandibular, which provide sensory innervation to structures of the face, sinuses, and portions of the cranial vault. The mandibular nerve also innervates muscles of mastication. Clinical features include loss of facial and intra-oral sensation and weakness of jaw closure. Common conditions affecting the nerve include brain stem ischemia, INFRATENTORIAL NEOPLASMS, and TRIGEMINAL NEURALGIA.
Diseases characterized by loss or dysfunction of myelin in the central or peripheral nervous system.
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.
A relatively common sequela of blunt head injury, characterized by a global disruption of axons throughout the brain. Associated clinical features may include NEUROBEHAVIORAL MANIFESTATIONS; PERSISTENT VEGETATIVE STATE; DEMENTIA; and other disorders.
General or unspecified injuries to the posterior part of the trunk. It includes injuries to the muscles of the back.
Traumatic injuries involving the cranium and intracranial structures (i.e., BRAIN; CRANIAL NERVES; MENINGES; and other structures). Injuries may be classified by whether or not the skull is penetrated (i.e., penetrating vs. nonpenetrating) or whether there is an associated hemorrhage.
Accidents on streets, roads, and highways involving drivers, passengers, pedestrians, or vehicles. Traffic accidents refer to AUTOMOBILES (passenger cars, buses, and trucks), BICYCLING, and MOTORCYCLES but not OFF-ROAD MOTOR VEHICLES; RAILROADS nor snowmobiles.
The physical activity of a human or an animal as a behavioral phenomenon.
The directed transport of ORGANELLES and molecules along nerve cell AXONS. Transport can be anterograde (from the cell body) or retrograde (toward the cell body). (Alberts et al., Molecular Biology of the Cell, 3d ed, pG3)
The most common inhibitory neurotransmitter in the central nervous system.
A spectrum of clinical liver diseases ranging from mild biochemical abnormalities to ACUTE LIVER FAILURE, caused by drugs, drug metabolites, and chemicals from the environment.
A class of statistical methods applicable to a large set of probability distributions used to test for correlation, location, independence, etc. In most nonparametric statistical tests, the original scores or observations are replaced by another variable containing less information. An important class of nonparametric tests employs the ordinal properties of the data. Another class of tests uses information about whether an observation is above or below some fixed value such as the median, and a third class is based on the frequency of the occurrence of runs in the data. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed, p1284; Corsini, Concise Encyclopedia of Psychology, 1987, p764-5)

  • With vast experience in surgically managing even the most complex peripheral nerve injuries, the Peripheral Nerve Surgery Center offers the skilled intervention you need to address pain and restore optimal function. (
  • To request an appointment or refer a patient, please contact the Johns Hopkins Peripheral Nerve Surgery Center at 410-614-9923 . (
  • Iatrogenic injuries during surgery are becoming more widely documented as we begin to see surges in insurance claims. (
  • 10 patients suffered facial nerve damage (secondary to ear and parotid gland surgery) and 10 suffered trigeminal nerve injury (secondary to maxilary sinus surgery). (
  • The high risk procedures that often result in peripheral nerve damage include: osteosynthesis, arthrodesis, posterior triangle lymph node biopsies, carpal tunnel release, surgery for varicose veins, baker cyst excision and inguinal herniorrhaphy. (
  • Mingo-Robinet reported a permanent femoral nerve palsy secondary to tourniquet use in patella fracture surgery. (
  • Iatrogenic causes such as, inadvertent nerve injury during any type of surgery. (
  • Not everyone who has nerve compression syndrome qualifies for surgery. (
  • He was Nuffield Professor of Orthopaedic Surgery at the University of Oxford, where his work and publications on peripheral nerve injuries gained him an international reputation. (
  • In mirror image pain, IL-6 protein and mRNA in both lumbar and cervical dorsal root ganglia were elevated bilaterally following unilateral chronic compression injury of the sciatic nerve [ 7 ]. (
  • The one exception is the PNS nerves that live in the upper portion of the spine (the cervical nerve roots) and lower portion of the spine (the lumbar nerve roots). (
  • A reversible local conduction block at the site of the injury. (
  • In order to fully determine the extent of the damage to the nerve, the doctor may order an electrical conduction test to determine the passage of electrical currents through the nerves. (
  • Two of these tests are electromyography and nerve conduction velocity. (
  • Nerve conduction study. (
  • In 1943, Seddon described three basic types of peripheral nerve injury that include: It is a temporary interruption of conduction without loss of axonal continuity. (
  • Conduction is intact in the distal segment and proximal segment, but no conduction occurs across the area of injury. (
  • Recovery of nerve conduction deficit is full, and requires days to weeks. (
  • There is no nerve conduction distal to the site of injury (3 to 4 days after injury). (
  • Injury of a major nerve trunk frequently results in considerable disability associated with loss of sensory and motor functions. (
  • We recorded single units in sensory pain-associated nuclei, the posterior nucleus of the thalamus (PO) and spinal trigeminal nucleus caudalis (SpVc), which have previously been causally associated with pain after spinal cord injury. (
  • In addition, tables listing innervations of peripheral muscles and joints act as ready references in discerning which muscles and nerves should be addressed during rehabilitation. (
  • In some, the disease seems to start after an injury -- muscle weakness at the site of the injury slowly spreads to new areas until weakness in the muscles responsible for breathing causes suffocation. (
  • A nerve injury can affect your brain's ability to communicate with your muscles and organs. (
  • Motor nerves - responsible for controlling the movement of all muscles, such as those utilized for talking, walking, gripping things, etc. (
  • Nogo-A is not detectable in peripheral nerve myelin. (
  • It involves loss of the relative continuity of the axon and its covering of myelin, but preservation of the connective tissue framework of the nerve (the encapsulating tissue, the epineurium and perineurium, are preserved). (
  • When a peripheral nerve injury is present, generally the nerve membrane is damaged or the insulation (myelin sheath) is damaged. (
  • Birth-related brachial plexus palsy refers to injury of the nerves that lead from the cervical (neck) spinal cord to the arm. (
  • Treatment also is offered for common and more complex nerve-compression injuries. (
  • Nerve injury related to tourniquets results from two pathological processes: mechanical compression and neural ischaemia. (
  • This is unfortunately the location of compression of a nerve that may occur from a disc herniation. (
  • This insulation can be damaged by compression just as the nerve membrane itself can be injured. (
  • compression such as from a disc herniation, blunt impact (this can also occur from a disc herniation) and finally, a stretch injury. (
