BACKGROUND Obesity indices (i.e. BMI, waist-to-hip ratio) show differential relationships to other health outcomes, though their association to neurocognitive outcome is unclear. METHODS We examined whether central obesity would be more closely associated with cognitive function in 1,703 participants from the Baltimore Longitudinal Study of Aging. RESULTS Longitudinal mixed-effects regressi...

BACKGROUND In healthy teenagers, obesity and physical inactivity are the two main factors that affect respiratory function. The aim of this study was to evaluate the effect of aerobic exercise training on improving lung function in overweight and obese students. MATERIALS AND METHODS Thirty overweight or obese subjects with poor endurance performance and mild deterioration of respiratory indi...

lung function tests were performed in 122 workers of vegetable oil refineries in tehran area. the results show an increase in respiratory impairment with age and length of exposure. among the four indices of lung function that were calculated, fev1 %fvc and fef 25-75% pfef 25-75 showed the greatest decrease with age and length of exposure, while fvc% pfvc and fev1% pfev1 were essentially within...

The autocorrelation function of the all-pole filter given by the conventional linear prediction (LP) matches exactly the autocorrelation function of the input signal between indices 0 and m, when the prediction order equals m. This study describes a recently developed technique, Weighted-Sum Line Spectrum Pair (WLSP), where an all-pole filter is defined by using a sum of weighted LSP (Line Spec...

knowledge about spatial soil variation in terms of measured pedodiversity offers the possibility to estimate the quality and variance within a soil map. diversity indices and abundance distribution models are statistical tools which ecologists have applied for decades for analyzing the intrinsic regularities of various ecological entities. in this study relationships between soils evolution, la...

Purpose: Hypertension is known to cause changes in the LV that impact negatively on LA both structurally and functionally posing clinically significant risk patients. size assessment until recently was limited determination of linear diameter much has not been elucidated with respect left atrial volume (indices) cardiac indices as surrogates for function. It therefore important see how (size, v...

Volume loading normalizes tolerance to a simulated hemorrhagic challenge in heat-stressed individuals, relative to when these individuals are thermoneutral. The mechanism(s) by which this occurs is unknown. This project tested two unique hypotheses; that is, the elevation of central blood volume via volume loading while heat stressed would 1) increase indices of left ventricular diastolic funct...

BACKGROUND The appropriate evaluation of atrial electrical function is only possible by means of invasive electrophysiology techniques, which are expensive and therefore not suitable for widespread use. Mechanical atrial function is mainly determined from atrial volumes and volume-derived indices that are load-dependent, time-consuming and difficult to reproduce because they are observer-depend...
