results trail making test part b cognitive test showed statistically significant in comparison for pre and post exposure of anesthetics. this difference was seen in the desflurane group. other cognitive tests did not show differences on exposure to the anesthetic gases. conclusions this study questioned the difference between volatile anesthetic agent’s effects on patients completing a battery ...

We evaluated the association between physical activity and cognitive function among a national sample of the broader U.S. adult population, with consideration by social risk. Data from the 1999-2002 National Health and Nutrition Examination Survey (NHANES) were used to identify 2031 older adults, ages 60-85. Social risk was classified by measuring four NHANES variables, namely poverty level, ed...

Cognitive slowing is a prevalent symptom observed in Gulf War Illness (GWI). The present study assessed the extent to which functional connectivity between dorsolateral prefrontal cortex (DLPFC) and other task-relevant brain regions was predictive of GWI-related cognitive slowing. GWI patients (n = 54) and healthy veteran controls (n = 29) were assessed on performance of a processing speed task...

BACKGROUND Cognitive function in people with multiple sclerosis (PwMS) is associated with gender differences and the use of smoked/ingested cannabis. OBJECTIVE The objective of this report is to explore a possible gender-cannabis interaction associated with cognitive dysfunction in PwMS. METHODS A retrospective analysis was undertaken of cognitive data collected from 140 PwMS. A general lin...

BACKGROUND A number of studies have investigated cognitive impairment in paediatric patients with multiple sclerosis (MS) but deficits regarding executive functions have not been comprehensively assessed up to now. This study was meant to explore cognitive impairment in German paediatric MS patients with a focus on deficits in executive functions and relate these to clinical disease parameters....

BACKGROUND poor cognitive and motor performance predicts neurological dysfunction. Variable performance may be a subclinical indicator of emerging neurological problems. OBJECTIVE examine the cross-sectional association between a clinically accessible measure of variable walking and executive function. METHODS older adults aged 60 or older from the Baltimore Longitudinal Study of Aging (n =...

The Benford's law has been proposed in the very past in order to modelize the probability distribution of the rst digit in a set of natural numbers. In this report, we prove that this law is validated in the digital images domain, not for the images but for the magnitude of their gradient. We show, experimentaly, that this also apply for the laplacian pyramid code. This yields to the eld of ent...

OBJECTIVE Retrograde cerebral perfusion (RCP) is used as an adjunctive method to hypothermic circulatory arrest to enhance cerebral protection in patients undergoing thoracic aortic surgery. It remains unclear whether RCP provides improved neurological and neuropsychological outcome. METHODS Forty-six patients undergoing thoracic aortic surgery using RCP, and 28 undergoing coronary artery byp...

In this paper a new adaptive entropy coding scheme for video compression is presented. It utilizes an adaptive arithmetic coding technique to better match the first order entropy of the coded symbols and to keep track of nonstationary symbol statistics. In addition, remaining symbol redundancies will be exploited by context modeling to further reduce the bit-rate. A novel approach for coding of...
