Diurnal patterns of plasma euglobulin fibrinolytic activity, estimated by the fibrin plate method, were determined in groups of young normal and older normal subjects, in subjects with type IV hyperlipoproteinemia, and in subjects with coronary artery disease who had normal lipid profiles. The marked diumal increases in fibrinolytic activity observed in the young normal subjects were significan...

BACKGROUND Downward shifts in blood volume with changing position generally cause tachycardic responses. Age-related decreases in vagal nerve activity could contribute to orthostatic hypotension in older individuals. Fowler's position is a reclined position with the back between 30° and 60°, used to facilitate breathing, eating, and other routine daily activities in frail and elderly patients. ...

Spatial attention and memory were compared in young and old subjects using non-delayed and delayed matching-to-sample tests. Both young and older subjects revealed a right hemisphere superiority for spatial processing. Older subjects were as accurate as young controls in the non-delay task supporting preserved attention ability in this spatial task. However, older subjects were impaired at 3 s ...

PPH (postprandial hypotension), leading to increased morbidity and mortality, is an important clinical problem, particularly in the elderly and individuals with autonomic dysfunction. The magnitude of the postprandial fall in BP (blood pressure) appears to be dependent on the rate of nutrient entry into the small intestine and may be related to changes in splanchnic blood flow and sympathetic n...

background: diabetes mellitus is a serious public health problem worldwide and particularly in developing countries. in algeria, this metabolic disorder occurs with a wide variety or atypical forms that linked to multiple risk factors including local habits and traditions. this study aimed to determine the impact of risk factors (metabolic syndrome, social, cultural, physical activity, family h...

We describe an interactive, computer-based test inspired by the Trail Making Test (TMT). With this new test, young (mean age=20.4 years) and older subjects (mean age=74.9 years) used natural, pointing responses to order series of items, either numbers, letters, or intermixed letters and numbers. This interactive test, which eliminates several deficiencies of TMT, assesses subjects’ baseline spe...

Although cerebral autoregulation (CA) appears well maintained during mild to moderate intensity dynamic exercise in young subjects, it is presently unclear how aging influences the regulation of cerebral blood flow during physical activity. Therefore, to address this question, middle cerebral artery blood velocity (MCAV), mean arterial pressure (MAP), and the partial pressure of arterial carbon...

background: chloral hydrate (ch) is a sedative agent that is widely used in infants and children for several decades. the purpose of this study was to evaluate the safety and efficacy of ch before general anesthesia in pediatric population undergoing eye examination. methods: 165 pediatric patients with retinal tumor were examined from december 2014 to may 2015. 158 (95.7%) children were sedate...
