OBJECTIVE The objective of this study was to examine the effect of Cs-4 (Cordyceps sinensis) on exercise performance in healthy elderly subjects. DESIGN Twenty (20) healthy elderly (age 50-75 years) subjects were enrolled in this double-blind, placebo-controlled, prospective trial. The subjects were taking either Cs-4 333 mg or placebo capsules 3 times a(More)
Pomegranate juice (PJ), a rich source of polyphenols including ellagitannins, has attracted much attention due to its reported health benefits. This has resulted in the consumption of liquid and powder pomegranate extracts as alternatives to PJ. Therefore establishing the bioavailability of polyphenols from these extract preparations is necessary. Sixteen(More)
BACKGROUND There is concern that recommending protein-enriched meal replacements as part of a weight management program could lead to changes in biomarkers of liver or renal function and reductions in bone density. This study was designed as a placebo-controlled clinical trial utilizing two isocaloric meal plans utilizing either a high protein-enriched (HP)(More)
BACKGROUND Various adipose tissue factors have been implicated as biomarkers of the metabolic syndrome (MS). The objective of this study was to assess which specific adipose tissue factors would discriminate the presence of MS in a strictly obese population meeting waist circumference (WC) criteria for the MS. METHODS This was a cross-sectional study of(More)
BACKGROUND While high protein diets have been shown to improve satiety and retention of lean body mass (LBM), this study was designed to determine effects of a protein-enriched meal replacement (MR) on weight loss and LBM retention by comparison to an isocaloric carbohydrate-enriched MR within customized diet plans utilizing MR to achieve high protein or(More)
Obesity prevalence and average body composition vary by US race and gender. Asian Americans have the lowest prevalence of obesity. Relying on body-mass index (BMI) to estimate obesity prevalence may misclassify subgroups that appear normally weighted but have excess body fat. We evaluated percentage body fat (PBF) and BMI to determine whether BMI reflects(More)
BACKGROUND Human exercise capacity declines with advancing age. These changes often result in loss of physical fitness and more rapid senescence. Nitric oxide (NO) has been implicated in improvement of exercise capacity through vascular smooth muscle relaxation in both coronary and skeletal muscle arteries, as well as via independent mechanisms.(More)
According to the Digital Television Transition and Public Safety Act of 2005, broadcasters across the United States must complete their switch from analog to digital video in 2009, rendering millions of television sets obsolete. Viewers will be required to purchase converter boxes in order to view the new high-definition (HD) signals. In addition to these(More)
