Background: Urtica dioica has been used as antihypertensive, antihyperlipidemic and antidiabetic herbal medicine. The purpose of this study was to study the effect of hydroalcoholic extract of Urtica dioica on fructose-induced insulin resistance rats. Methods: Forty male Wistar rats were randomly divided into five groups including control, fructose, extract 50, extract 100 and extract 2...

BACKGROUND Animal studies have suggested beneficial effects of conjugated linoleic acid (CLA) in reducing body fat mass and improvement in the serum lipid profile and glycemia. However, these effects are controversial in humans. The purpose of this study was to investigate the effects of microencapsulated CLA supplementation on body composition, body mass index, waist circumference, and blood p...

Dietary supplementation of conjugated linoleic acids (CLA) is known to have some beneficial effects such as anti-carcinogenic and anti-obesity effects in several animal species, while it also induces insulin resistance and fatty liver, especially in mice. To explore the possible factors responsible for the CLA-induced insulin resistance, we examined the plasma and mRNA expression levels of seve...

Several studies have sought to clarify the association between adolescent obesity and psychological distress. Recently, a biological link between leptin resistance and depression has been proposed. The aim of the present study was to examine changes in leptin concentrations as a potential predictor of reduced depression symptoms in obese adolescents during long-term interdisciplinary weight los...

Methods Weight, BMI, bench press 1 RM, leg press 1 RM, body composition parameters, VO2Max, fasting glucose and lipid panels were evaluated before (pre-test) and after (post-test) 56 days (8 weeks) of resistance and cardiovascular training, performed three times per week (totaling 24 workouts). Resistance training consisted of two sets of 12 repetitions of the following exercises: seated leg pr...

BACKGROUND & OBJECTIVES Conjugated linoleic acid (CLA) reduces fat deposition in the body, but the mechanism of action is not clear. The present study was conducted to investigate the effects of CLA on body fat metabolism. Since milk fat is the best natural source of dietary CLA, intervention of non-fat milk constituents on CLA treatment was also investigated. METHODS Diets containing CLA (1%...

To evaluate the extent to which fat mass contributes to serum osteopontin (OPN) concentration, we investigated whether serum OPN levels are decreased by exercise-induced fat mass loss and whether they are associated with body fat percentage in obese humans. Twenty‑three female college students were recruited to participate in an 8‑week body weight control program. Body composition [body weight,...
