Astaxanthin decreased oxidative stress and inflammation and enhanced immune response in humans

2010.03.05T00:00:00Z
Astaxanthin modulates immune response, inhibits cancer cell growth, reduces bacterial load and gastric inflammation, and protects against UVA-induced oxidative stress in in vitro and rodent models. Similar clinical studies in humans are unavailable. Our objective is to study the action of dietary astaxanthin in modulating immune response, oxidative...read more

Resistance training in overweight women on a ketogenic diet conserved lean body mass while reducing body fat

2010.03.02T00:00:00Z
18 untrained women between 20 and 40 years with BMI [greater than or equal to] 25 kg*m-2 were randomly assigned into the Ex or Lc+Ex group. Both groups performed 60-100 min of varied resistance exercise twice weekly. Dietary estimates were based on two 4-day weighed records. Body composition was estimated using Dual Energy X-ray Absorptiometry. Fasting...read more

Lack of association between dietary fructose and hyperuricemia risk in adults

2010.03.01T00:00:00Z
The highest added or total fructose intake (quartiles by grams or % energy) was not associated with an increase of hyperuricemia risk compared to the lowest intake with or without adjustment (odds ratios=0.515-0.992). The associations of alcohol and fiber intakes with the risk were also determined. Compared to the lowest intake, the highest alcohol...read more

Comparative effects of oleoyl-estrone and a specific beta3-adrenergic agonist (CL316,243) on the expression of genes involved in energy metabolism of rat white adipose tissue

2010.02.25T00:00:00Z
In the present study we investigated the effect of OE (oral gavage) and/or B3A (subcutaneous constant infusion) administration for 10 days to overweight male rats, compared with controls, on three distinct white adipose tissue (WAT) sites: subcutaneous inguinal, retroperitoneal and epididymal. Tissue weight, DNA (and, from these values cellularity),...read more

Serum HER-2 concentration is associated with insulin resistance and decreases after weight loss

2010.02.25T00:00:00Z
Serum HER-2 concentrations were positively associated with BMI and waist circumference (both r=0.18, p=0.02), post-load glucose (r=0.28, p=0.001) and fasting triglycerides (r=-0.26, p=0.001); and negatively associated insulin sensitivity (r=-0.29, p=0.002, n=109). Subjects with type 2 diabetes showed significantly increased soluble serum HER-2 concentrations...read more

Consuming cassava as a staple food places children 2-5 years old at risk for inadequate protein intake, an observational study in Kenya and Nigeria

2010.02.26T00:00:00Z
Inadequate protein intake is known to be deleterious in animals. Using WHO consensus documents for human nutrient requirements, the protein:energy ratio (P:E) of an adequate diet is > 5%. Cassava has a very low protein content. This study tested the hypothesis that Nigerian and Kenyan children consuming cassava as their staple food are at greater...read more

Weight loss in individuals with metabolic syndrome given DASH diet counseling when provided a low sodium vegetable juice: a randomized controlled trial

2010.02.23T00:00:00Z
Metabolic syndrome, a constellation of metabolic risk factors for type 2 diabetes and cardiovascular disease, is one of the fastest growing disease entities in the world. Weight loss is thought to be a key to improving all aspects of metabolic syndrome. Research studies have suggested benefits from diets rich in vegetables and fruits in helping individuals...read more

Dietary intake of Senegalese adults

2010.02.18T00:00:00Z
The aim of this work is to identify major food sources and dietary constituents of Senegalese adults. We conducted a cross-sectional study, using a single 24-hour dietary recall interview. Foods were classified into food groups based on similarities in nutrient content or use. Food groups included foods consumed individually, or as part of food mixtures...read more

Study protocol: Cost-effectiveness of transmural nutritional support in malnourished elderly patients in comparison with usual care

2010.02.10T00:00:00Z
Malnutrition is a common consequence of disease in older patients. Both in hospital setting and in community setting oral nutritional support has proven to be effective. However, cost-effectiveness studies are scarce. Therefore, the aim of our study is to investigate the effectiveness and cost-effectiveness of transmural nutritional support in malnourished...read more

Efficacy of Lactic Acid Bacteria (LAB) supplement in management of constipation among nursing home residents

2010.02.05T00:00:00Z
Constipation is a significant problem in the elderly, specifically nursing home and/or extended-care facility residents are reported to suffer from constipation. Lactic acid bacteria (LAB) are beneficial probiotic organisms that contribute to improved nutrition, microbial balance, and immuno-enhancement of the intestinal tract, as well as diarrhea...read more

The effects of theaflavin-enriched black tea extract on muscle soreness, oxidative stress, inflammation, and endocrine responses to acute anaerobic interval training: a randomized, double-blind, crossover study

2010.02.23T00:00:00Z
Muscle soreness and decreased performance often follow a bout of high-intensity exercise. By reducing these effects, an athlete can train more frequently and increase long-term performance. The purpose of this study is to examine whether a high-potency, black tea extract (BTE) alters the delayed onset muscle soreness (DOMS), oxidative stress, inflammation...read more

The effects of a pre-workout supplement containing caffeine, creatine, and amino acids during three weeks of high-intensity exercise on aerobic and anaerobic performance

2010.02.15T00:00:00Z
Twenty-four moderately-trained recreational athletes (mean +/- SD age = 21.1 +/- 1.9 yrs; stature = 172.2 +/- 8.7 cm; body mass = 66.2 +/- 11.8 kg, VO2max = 3.21 +/- 0.85 l * min-1, percent body fat = 19.0 +/- 7.1%) were assigned to either the active supplement (GT, n=13) or placebo (PL, n=11) group. The active supplement (Game Time(R), Corr-Jensen...read more

Creatine-induced activation of antioxidative defence in myotube cultures revealed by explorative NMR-based metabonomics and proteomics

2010.02.04T00:00:00Z
Creatine is a key intermediate in energy metabolism and supplementation of creatine has been used for increasing muscle mass, strength and endurance. Creatine supplementation has also been reported to trigger the skeletal muscle expression of insulin like growth factor I, to increase the fat-free mass and improve cognition in elderly, and more explorative...read more
