Background: Central venous obstruction (stenosis or occlusion) is common in patients with renal failure on hemodialysis and may be associated with intracranial hypertension (IH). Causes include vein injury from an endoluminal device, lumen obstruction from a device or thrombus, external vein compression, and high venous flow leading to vein intimal hyperplasia. A combination of high venous flow and central venous obstruction can lead to intracranial venous hypertension, impaired cerebrospinal...
Abstract: The mechanism for stable gaze-holding requires a neural integrator that converts pulse of neural discharge to steady firing rate. The integrator is feedback-dependent, impaired feedback manifests as either “unstable” integration when it is too much or “leaky” when it is too little. The “unstable” integrator is known to cause sinusoidal oscillations of the eyes called pendular nystagmus, whereas the “leaky” integrator causes jerky eye oscillations called gaze-evoked nystagmus. We hypothesized...

Background: Restoration of vision in patients blinded by advanced optic neuropathies requires technologies that can either 1) salvage damaged and prevent further degeneration of retinal ganglion cells (RGCs), or 2) replace lost RGCs. Evidence Acquisition: Review of scientific literature. Results: In this article, we discuss the different barriers to cell-replacement based strategies for optic nerve regeneration and provide an update regarding what progress that has been made to overcome...
Abstract: A 74-year-old man with vasculopathic risk factors presented to the emergency room with a chief complaint of peripheral vision loss resulting from an intracranial hemorrhage in his right parietal and occipital lobes. Urgent craniotomy and ventriculostomy led to a stable clinical condition with subsequent development of a crossed quadrant homonymous hemianopsia (checkerboard visual field) due to a new right parieto-occipital infarct superimposed on a prior left occipital infarct. This...

Abstract Temperature determines the rates of all biochemical and biophysical processes, and is also believed to be a key driver of macroevolutionary patterns. It is suggested that physiological constraints at low temperatures may diminish the fitness advantages of otherwise beneficial mutations; by contrast, relatively high, benign, temperatures allow beneficial mutations to efficiently show their phenotypic effects. To experimentally test this ‘mutational effects’ mechanism, we examined the fitness...
