A Brain tumor is a growth of cells in the brain or near it. tumors can happen tissue close by locations include nerves, pituitary gland, central nervous system , meninges and membranes that cover surface brain[1]. glioma forms spinal cord makes an appearance from glial stem progenitor cells. Glial are type cell generally present system. Gliomas predominantly occur and, rarely, cord. They grow a...

Hamel, Edith. Perivascular nerves and the regulation of cerebrovascular tone. J Appl Physiol 100: 1059–1064, 2006; doi:10.1152/japplphysiol.00954.2005.— Brain perfusion is tightly coupled to neuronal activity, is commonly used to monitor normal or pathological brain function, and is a direct reflection of the interactions that occur between neuronal signals and blood vessels. Cerebral blood ves...

Damage of nerves occurs when an external force traumatically injures the nerves which cause a host of physical, cognitive and behavioral effects can range from complete recovery or permanent disability or death. The delineation of the trauma in brain, abdomen and lungs is a challenging task due to variations in shapes and image quality. In this method we present a semi automatic method for extr...

Subacute combined degeneration ( SCD) due to vitamin B12 deficiency is common in North of Europe but sometimes it is seen in Iran. It can develop before the symptoms of anemia is obvious, with myelin injury and then axon and even neuron destruction in spinal cord, brain, optic and peripheral nerves. In this study two cases are reported; in the first patient, this disease in manifested by vitami...

ABSTRACT Melioidosis is a potentially fatal disease that is endemic to tropical northern Australia and Southeast Asia, with a mortality rate of 14 to 50%. The bacterium Burkholderia pseudomallei is the causative agent which infects numerous parts of the human body, including the brain, which results in the neurological manifestation of melioidosis. The olfactory nerve constitutes a direct condu...

Using an antibody to gamma-aminobutyric acid (GABA), we examined the optic nerves and optic tracts from macaque monkeys at the light and electron microscopic levels to determine if there is a possible inhibitory projection from the retina to the brain. All of the monkeys (n = 5) had GABA immunopositive axons that were evenly distributed in their optic nerves. These immunopositive axons were sli...

conclusions obtained results demonstrate significant differences between intraneural and perineural injection pressures in the median, ulnar, and radial nerves. intraneural injection pressures show low specificity but high sensitivity suggesting that pressure monitoring might be a valuable tool in improving the safety and efficacy of peripheral nerve blockade in regional anesthesia. peripheral ...
