Abstract

CONSCIOUSNESS floats in the delicate ether of butterflies, brain spilt into itself, warbling through a garden of grey matter, an unmistakable interiority that does not emote, gabble or quack, is pre-syntax and babble, reigns like a cloud over the birth of flowers, gazes across a moat into the forest of pheromones and photons, the din of decibels, and into the reservoir of itself; a pool of unshattered meniscus, untouched by the tongue that comes out of the mouth, flicking the surface like trout. Mind sifts the pre-syllabic library in every ridge and rut, lifts on muslin wings beyond the circuitry, and waits for the anesthesia of sleep, when consciousness fibrillates, set free to orbit in the galaxy of Galileo's imagery. Without it, worlds that men propose, reality or dream, would be unmindfully comatose.

Post Ischemic Stroke Imaging and Its Clinical Relevance: A Systematic Review

“…Residual flow limits local blood flow. 1,2 The process of ischemia and reperfusion can stimulate the production of reactive oxygen species (ROS), mitochondrial dysfunction and glutamate release which will be followed by repeated depolarizations and can cause changes in electrolyte content both intra and extracellular. Changes in nerve excitability and electrolytes that occur suddenly in the early phase of a stroke can cause changes in the structure of the nerves in the peri-infraction area so that they can affect the survival of the nerves in that area.…”

“…Changes in nerve excitability and electrolytes that occur suddenly in the early phase of a stroke can cause changes in the structure of the nerves in the peri-infraction area so that they can affect the survival of the nerves in that area. 1,2,17 Lack of oxygen causes acidosis and triggers impaired enzyme function. Acidosis is followed by cerebral edema, especially in the glial tissue, and affects the microcirculation.…”

“…Cerebral ischemia impairs sodium-calcium exchange which also occurs in the plasma membrane of cells. 1,2 The resulting calcium influx causes the release of a number of neurotransmitters, including large amounts of glutamate, which in turn activates N-methyl-D-aspartate (NMDA) and other expression receptors. 17 This causes calcium influx, glutamate release, and local amplification of ischemia.…”

“…Both can be life-threatening. [1][2][3] Endothelial cell damage and loss, which exposes the subendothelium and leads to the activation of platelets by the subendothelium, activation of the clotting cascade, suppression of fibrinolysis, and blood stasis, can be examples of thrombogenic causes. Turbulence in the flow of blood can be caused by arterial stenosis, which can then raise the risk of thrombus development, atherosclerosis, and platelet compliance, all of which can contribute to the creation of blood clots that can clog arteries.…”

“…The prevalence of coronary heart disease, heart failure, and stroke seems to increase with increasing age of the respondents. 2,5,6 The incidence of stroke continues to increase with age. The higher a person's age, the higher the chance of having a stroke.…”
