BRAIN MAPPING IN NEUROSURGERY
Background and Aim: Brain mapping is a study of the anatomy and function of the CNS (central nervous system). Brain mapping has many techniques and these techniques are permanently changing and updating. From the beginning, brain mapping was invasive and for brain mapping, electrical stimulation of the exposed brain was needed. However, nowadays brain mapping does not require electrical stimula...
متن کاملPrions.
The discovery of infectious proteins, denoted prions, was unexpected. After much debate over the chemical basis of heredity, resolution of this issue began with the discovery that DNA, not protein, from pneumococcus was capable of genetically transforming bacteria (Avery et al. 1944). Four decades later, the discovery that a protein could mimic viral and bacterial pathogens with respect to the ...
متن کاملPrions.
Infectious proteins (prions) are usually self-templating filamentous protein polymers (amyloids). Yeast prions are genes composed of protein and, like the multiple alleles of DNA-based genes, can have an array of "variants," each a distinct self-propagating amyloid conformation. Like the lethal mammalian prions and amyloid diseases, yeast prions may be lethal, or only mildly detrimental, and sh...
متن کاملUpdate in neurosurgery - nanotechnology in neurosurgery.
Nanotechnology define the science and engineering providing entirely new tools and capabilities, concerned with the design, synthesis, characterization and application of materials and devices that have a functional organization in at least 1 dimension on the nanometer (one billionth of a meter) capable to interact with cells and tissues at a molecular sub cellular level with a high degree of f...
متن کاملPrions
plants are cloaked in hundreds of tiny projections, known as trichomes. These structures vary in function, shape, size and spacing from species to species, and it’s not known whether similar cellular differentiation programs are responsible for making trichomes in different plants. Trichomes are clearly visible in the scanning electron micrograph of a wild-type Nicotiana tabacum seedling above ...
