Background and Aims: The insertion of ventriculoperitoneal (VP) and ventriculoatrial (VA) shunts is the first-line treatment of patients with hydrocephalus and normal-pressure hydrocephalus. The provision of a safety profile for shunting in the treatment of hydrocephalus patients is very important. This study aimed to determine the success rates and complications of VP and VA shunting in patien...

of an excessive accumulation of cerebrospinal fluid (CSF) within the cranial cavity with subsequent dilation of the ventricular system. Hydrocephalus has been characterized by the anatomic relationship of the underlying disease process and abnormal pressure differences. Internal and external hydrocephalus refer to increased fluid accumulation within the ventricular and subarachnoid spaces, resp...

Continuous monitoring of the cerebrospinal fluid pressure and observation of the pressure during intrathecal infusion of normal saline at two rates were performed in patients with communicating hydrocephalus and cerebral atrophy of other causes. Constant or temporarily increased cerebrospinal fluid pressure was observed only in communicating hydrocephalus. Reduction of intracranial pressure by ...

This purpose of this paper is to study the signal-to-interference (SIR) model used in power control problems to incorporate random network matrices with log-normally distributed coefficients. Related models on stochastic programming are presented and applied to the random SIR model.

Experiments were conducted with containerized ;Tahiti' lime (Citrus latifolia Tan.) trees in order to define conditions needed to induce flowering. Cyclical or continuous water stress for 4 to 5 weeks induced flowering. Moderate (-2.25 megapascals, midday) or severe (-3.5 megapascals, midday) water stress as measured by leaf xylem pressure potential, for as little as 2 weeks induced flowering, ...

The aim of this study was to determine whether the improvement of cerebrospinal fluid (CSF) flow dynamics by CSF shunting, can suppress the oligomerization of amyloid β-peptide (Aβ), by measuring the levels of Alzheimer's disease (AD)-related proteins in the CSF before and after lumboperitoneal shunting. Lumbar CSF from 32 patients with idiopathic normal pressure hydrocephalus (iNPH) (samples w...
