The effect of combining omega-3 fatty acid (n-3 FA) supplementation and exercise training treatment on postprandial lipemia (PPL) has not been studied. The purpose of this study was to examine the interaction of n-3 FA and exercise training in attenuating PPL after a high-fat meal. Previously sedentary, overweight, subjects (n=22; ...

BACKGROUND: Full-term neonates produce tears normally, but neonatal tear film is modified to resist evaporation with a thick lipid layer that allows lower spontaneous blink rates. This adaptation presumably prevents drying of the ocular surface during long inter-blink periods. However, tear-film stability is not only based on the integrity of ...

BACKGROUND: Aerobic exercise is believed to reduce the risk of cardiovascular disease partially through increasing serum levels of high-density lipoprotein cholesterol (HDL-C). However, this effect varies considerably among exercise intervention studies. METHODS: Electronic database searches of MEDLINE (1966-2005) for randomized controlled trials that examined the effect of exercise training on ...

Habitual exercisers enjoy considerable protection from coronary heart disease (CHD). Often, however, only modest differences in traditional CHD risk factors are apparent between habitual exercisers and their sedentary counterparts. For this reason, there is increasing interest in novel predictors of CHD, such as a preponderance of small, dense low-density lipoprotein ...

A novel hypothesis-free multivariate screening methodology for the study of human exercise metabolism in blood serum is presented. Serum gas chromatography/time-of-flight mass spectrometry (GC/TOFMS) data was processed using hierarchical multivariate curve resolution (H-MCR), and orthogonal partial least-squares discriminant analysis (OPLS-DA) was used to model the systematic variation related to the ...

Endurance exercise training improves plasma lipoprotein and lipid profiles and reduces cardiovascular disease risk. However, the effect of endurance exercise training, independent of diet and body fat phenotypes, on plasma lipoprotein subfraction particle concentration, size, and composition as measured by nuclear magnetic resonance (NMR) spectroscopy is not known. We hypothesized ...

BACKGROUND AND AIM: The -250G/A promoter polymorphism of the hepatic lipase gene has been associated with changes in the activity of the enzyme. We investigated whether this polymorphism modifies the postprandial response of triacylglycerol-rich lipoproteins (TRL) in young normolipemic males. METHODS AND RESULTS: Fifty-one healthy apolipoprotein (apo) E3/E3 male volunteers ...

Exercise has beneficial effects on lipoproteins. Little is known about how long the effects persist with detraining or whether the duration of benefit is effected by training intensity or amount. Sedentary, overweight subjects (n = 240) were randomized to 6-mo control or one of three exercise groups: 1) high-amount/vigorous-intensity exercise; ...

Oxidative damage to lipoproteins, in particular low density lipoprotein (LDL), is known to play a role in a number of diseases associated with ageing such as cardiovascular disease, atherosclerosis, arthritis, dementia and the metabolic syndrome. Physical activity or exercise can alter the balance of oxidative and anti-oxidative species within the ...

Cystatin C, an alternative serum measure of kidney function, is a stronger predictor of cardiovascular events than creatinine or estimated glomerular filtration rate (eGFR). We hypothesized that serum cystatin C concentration would have a stronger more linear association with cardiovascular functional status than creatinine-based measures in outpatients with established coronary ...

Plant sterols combined with exercise beneficially alter lipid profiles in hypercholesterolemic adults. Although the mechanism by which plant sterols favorably modulate lipid levels is well established, no trial to date has examined the effect of exercise, alone or combined with plant sterols, on cholesterol kinetics. Thus, the current objective was ...

Beneficial effects of physical exercise include improved insulin sensitivity, which may be affected by a modulated release of adiponectin, which is exclusively synthesized in white adipose tissue and mediates insulin sensitivity. Adiponectin circulates in three different oligomers, which also have a distinct biological function. We therefore aimed to investigate the ...

BACKGROUND: High-sensitivity C-reactive protein (hsCRP) is promoted as an independent predictor of atherosclerotic risk. In addition, cardiorespiratory fitness is inversely related to hsCRP in single-sex cross-sectional analyses. Our objective was to determine if modulating fitness with exercise training imposes changes in high-sensitivity C-reactive protein in a mixed-sex population at risk ...

The intestine propels and evacuates large gas loads without detectable phasic contractions by manometry. We hypothesized that intestinal gas motion is produced by changes in gut tone and capacitance. In 13 healthy subjects, changes in duodenal tone were measured by a barostat during continuous perfusion of lipids (Intralipid, 1 kcal ...

Streptomycin is an aminoglycoside antibiotic with a well-known antituberculosis activity; it is commonly used in clinical practice because it is effective and cheap. However, streptomycin has severe ototoxic effects. The delayed and gradual onset may suggest that a metabolic derivative of the antibiotic could be a potential contributor to ototoxicity. ...
