Type III intermediate filament proteins that assemble into neurofilaments, the major cytoskeletal element in nerve axons and dendrites. They consist of three distinct polypeptides, the neurofilament triplet. Types I, II, and IV intermediate filament proteins form other cytoskeletal elements such as keratins and lamins. It appears that the metabolism of neurofilaments is disturbed in Alzheimer's disease, as indicated by the presence of neurofilament epitopes in the neurofibrillary tangles, as well as by the severe reduction of the expression of the gene for the light neurofilament subunit of the neurofilament triplet in brains of Alzheimer's patients. (Can J Neurol Sci 1990 Aug;17(3):302)
The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results.

Rapid and extreme blood loss leading to HEMORRHAGIC SHOCK.
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.
A prediction of the probable outcome of a disease based on a individual's condition and the usual course of the disease as seen in similar situations.

In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.

  • Penetrating head injuries involve an object penetrating the skull and entering into brain tissue. (
  • TBI can result when the head suddenly and violently hits an object, or when an object pierces the skull and enters brain tissue" (NINDS, 2010). (
  • It can also occur when an object pierces the skull and enters the brain tissue and when elevation in the intracranial pressure occurs and potentially dramatic changes in the blood flow within and to the brain. (
  • An object that penetrates brain tissue, such as a bullet or shattered piece of skull, also can cause traumatic brain injury. (
  • The human skull is designed to protect the brain and our air passages, as it contains 22 bones in the cranium and another 14 facial bones. (
  • If you slip on a rug or slip going down the stairs, there's a significant momentum that jostles the brain inside the skull to what's called a coup contrecoup injury, or back-and-forth kind of injury. (
  • Closed brain injury occurs when a person receives an impact to the head from an outside force, but the skull does not fracture or displace. (
  • The brain swells but has no place to expand, thus causing increased pressure within the skull which can force brain tissues to compress, causing further injury. (
  • TBI can result when the head suddenly and violently hits an object, or when an object ruptures the skull and enters brain tissue. (
  • The dura mater, the arachnoid layer, and another layer - the pia mater - all form what is known as the meninges, which keeps the brain floating inside the skull. (
  • The scalp bleeds a lot when it is cut, and when the skull is cracked or penetrated, pieces of it can get lodged in the brain. (
  • In a closed head injury, nothing penetrates your skull, but a closed head injury can be just as complicated and vicious as an open head injury, sometimes more so. (
  • During a closed head injury, the brain may slam against one portion of the skull, then bounce against the opposite side of the wall. (
  • Closed traumatic brain injury occurs when an object forcefully causes the brain to be jarred within the skull. (
  • Penetrating traumatic brain injury occurs when an object breaks through the skull, directly colliding with the brain and injuring it. (
  • This may require the surgeon to remove a portion of skull to give the brain more room to swell. (
  • A closed head injury occurs when the head suddenly and violently hits an object, but the object does not break through the skull. (
  • A penetrating head injury occurs when an object pierces the skull and enters the brain tissue. (

  • Lesions can be extra-axial, (occurring within the skull but outside of the brain) or intra-axial (occurring within the brain tissue). (
  • As the wave passes through the skull, cerebrospinal fluid, and through the brain, neurons undergo sequences of tension and compression for the duration of the blast wave. (
  • While cerebrospinal fluid normally acts as a buffer between the brain and skull, during moments of extreme force (i.e. car collision or physical contact sports), this barrier can be overcome, resulting in an impact as the brain rams into the skull. (
  • Secondary injuries can also occur including cerebral infection, swelling, bleeding, and increased intracranial pressure. (

  • Second impact syndrome is also known as recurrent traumatic brain injury and can occur when an individual has a second brain injury before the first injury has healed. (
  • Individuals experiencing second impact syndrome need to seek emergency medical treatment immediately as death can occur rapidly following the second injury. (
  • This does not always occur, but is a possibility, due to the type of injury sustained. (
  • However, a degree of healing does occur, and people have remarkable capacity to transcend their difficulties, to adjust, and to fix what can be fixed ( Brain Change And PTSD: Proof Recovery Is Possible ). (
  • Diffuse Axonal Injury (DAI) has been found to occur when strain exceeds 10%, and strain rates exceed 10 meters per second. (
  • These injuries are most commonly found on the battlefield, as explosions occur close enough to humans that the high intensity waves apply stresses and strains that greatly surpass neuron elastic thresholds. (
