Laboratory facilities use many varieties of contact bedding, including wood chips, paper products, and corncob, each with its own advantages and disadvantages. Corncob bedding, for example, is often used because of its high absorbency, ability to minimize detectable ammonia, and low cost. However, observations that mice eat the corncob lead to concerns that its use can interfere with dietary st...

CONTEXT Carbohydrate-restricted diets have been popular in recent years. The theoretical glycemic impact of these diets, compared with other popular weight-loss diets, has not been reported. OBJECTIVE To assess the glycemic index (GI) and glycemic load (GL) of 2 popular, carbohydrate-restricted diets (South Beach and Sugar Busters!) and compare them with a low-fat, high-carbohydrate diet (Orn...

AIM To investigate the role of AMPK activation and autophagy in mediating the beneficial effects of exercise and caloric restriction in obesity. METHODS Dietary-induced obesity mice were made and divided into 5 groups; one additional group of normal mice serves as control. Mice in each group received different combinations of interventions including low fat diet, caloric restriction, and exer...

KEY POINTS Three weeks of intensified training and mild energy deficit in elite race walkers increases peak aerobic capacity independent of dietary support. Adaptation to a ketogenic low carbohydrate, high fat (LCHF) diet markedly increases rates of whole-body fat oxidation during exercise in race walkers over a range of exercise intensities. The increased rates of fat oxidation result in reduc...

BACKGROUND Yogurt and prebiotic consumption has been linked to better health. However, to our knowledge, no longitudinal study has assessed the association of yogurt and prebiotic consumption with depression risk. OBJECTIVE We longitudinally evaluated the association of yogurt and prebiotic consumption with depression risk in a Mediterranean cohort. METHODS The SUN (Seguimiento Universidad ...

Early excessive weight gain is positively associated with later obesity, and yet the effect of weight gain during specific periods and the impact of infant feeding practices are debated. The objective of the present study was to examine the impact of weight gain in periods of early childhood on body composition at 3 years, and whether infant feeding modified the relationship between early growt...

Maternal nutrient restriction results in intrauterine growth restriction (IUGR) newborns that develop obesity despite normal postweaning diet. The epidemic of metabolic syndrome is attributed to programmed "thrifty phenotype" and exposure to Western diets. We hypothesized that programmed IUGR newborns would demonstrate greater susceptibility to obesity and metabolic abnormalities in response to...

Growth in utero is largely a reflection of nutrient and oxygen supply to the foetus. We studied the effects of Mn restriction per se, maternal Mn restriction, and postnatal high-fat feeding in modulating body composition, lipid metabolism and adipocyte function in Wistar/NIN (WNIN) rat offspring. Female weanling, WNIN rats received ad libitum for 4 months, a control or Mn-restricted diet and we...

The objective of this study was to evaluate effects of DDGS sources differing in quality to growingfinishing pigs on growth performance and carcass characteristics. Pigs (n = 448; BW = 62.7 ± 0.11 kg) were fed one of 4 experimental diets (14 pens/treatment; 8 pigs/pen) using a 2-phase feeding program to a final BW of 115.8 ± 0.23 kg. Diets consisted of a corn-soybean meal diet (CON), and diets ...

Background: A high-fat diet (HFD) and fat accumulation promote the oxidative stress formation, which in turn has hazardous effects on reproductive system and fertility. Therefore, the present study examines the potential positive effects of a restricted high-fat diet (RHFD) and antioxidants consumption on sperm parameters in rats. Methods: 48 male albino wistar rats divided to four groups (n=12...
