the eyes are organs that detect light and convert it into electro-chemical impulses in neurons. visual perception is the ability to interpret information and surroundings from the effects of visible light reaching the eye. medicine recognizes that altitudes above 1500 meters start to affect humans so that, the eye is very sensitive to restriction of its supply of oxygen. a dimming of vision acc...

spinal cord injury (sci)-induced systemic inflammatory response affects multiple organs outside the spi­nal cord. treatment options for such complications are lacking. valproic acid (vpa) is a histone deacetylase inhibitor, acting directly at the level of gene transcription by inhibiting histone deacetylation and making transcription sites more accessible. acetylation of histones is critical to...

Speeding is a major cause of traffic accidents and is estimated to be the cause of about 40% of fatalities in road accidents. Speed is a major accident risk factor and affects both rate and severity of traffic accidents. This importance has led to universal use of intelligent control systems for maintaining road safety by enforcing speed regulations. In this study, a modeling is carried out by ...
