background: coronary heart disease is one of the most important problems of public health. one risk factor is dyslipidemia. evidence from molecular and animal research and epidemiologic investigations indicate that calcium intake may influence lipid metabolism.but intervention studies have produced conflicting results.objective of this study was to determine the effects of calcium supplementati...

We assessed the effect of no exercise (Nex; control) and high exercise level (Hex; approximately 4 MJ/day) and two dietary manipulations [a high-fat diet (HF; 50% of energy, 700 kJ/100 g) and low-fat diet (LF; 20% of energy, 300 kJ/100 g)] on compensatory changes in energy intake (EI) and energy expenditure (EE) over 7-day periods. Eight lean men were each studied four times in a 2 x 2 randomiz...

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...

the bulk of our knowledge on immunosuppression in malnutrition comes from the experiments done on cell-mediated immunity. however, malnutrition-induced modifications of humoral immunity have been less understood. the objective of this study was to determine the effects of acute protein-energy malnutrition on serum levels of immunoglobulins and their subclasses in murine models. male and female ...

conclusions considering that neuronal function highly depends on environmental conditions, any adverse alteration may affect the function and morphology of neurons. in this regard, our results showed the adverse effects of protein malnutrition on the morphology of the purkinje cells of cerebellum. results the low-protein group did not gain weight as much as control group (p < 0.05). the diamete...

objective: melanocortin-4 receptor (mc4r) and agouti-related peptide (agrp) are involved in energy homeostasis in the rat. the aim of the present study was to evaluate the expression of mc4r and agrp mrnas in arcuate nucleus (arc) during long term malnutrition of female ovariectomized rats. materials and methods: ten female ovariectomized rats were divided into two equal groups (n=6) of normal ...

Research on the effect of low-fat intake on hearing is limited. This study aimed to elucidate the relationship between fat, carbohydrate and protein intake and the presence of hearing discomfort among the elderly. The Korean National Health and Nutrition Examination Survey was conducted from 2009 through to 2012. A total of 4615 participants ranging in age from 60 to 80 years underwent a pure-t...

I. Reduced intake of energy or protein per se decreased riboflavin requirement of the chicks under restricted feeding regimens. 2. In severe riboflavin deficiency (2.26 mg/kg diet), efficiency of utilization of both energy and protein was decreased significantly under ad lib. conditions of feeding. 3. Efficiency of utilization of energy (but not protein) was decreased significantly in borderlin...
