Enhancement of mammary tumor formation by dietary fat may be mediated via increased caloric intake. Three experiments were performed to study this relationship in 7,12-dimethylbenz(a)anthracene (DMBA)-treated female Sprague-Dawley rats: (a) highor low-fat isocaloric diets were fed in a crossover design; (b) low-fat, high-calorie and high-fat, low-calorie diets were fed in a crossover design; (c...

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...

Subcutaneous fat necrosis of the newborn (ScFN) is an uncommon condition caused by generalized and/or local tissue hypoperfusion. The skin lesions of ScFN tend to improve spontaneously. However, ScFN may also lead to complications which cause serious problems. The severity of the etiologic factors contributing to the development of the disease determines the severity of complications. Therefore...

The effects of early gestational undernutrition and subsequent refeeding patterns on offspring food intake, body weight and adiposity were examined. Pregnant rats were food restricted to 50% of their preconception intake levels during the first 2 weeks of pregnancy and were then either returned to ad libitum feeding or pair-fed to nonrestricted control rats. Male and female offspring of previou...

BACKGROUND Low-fat (LF) and high-fat (HF) weight loss diets improve brachial artery flow-mediated dilation (FMD) in obese individuals, although results are conflicting. Moreover, the role that adipose tissue plays in mediating these diet-related effects are unknown. OBJECTIVE This study examined how modulations in FMD by HF and LF diets relate to changes in adipocyte parameters. DESIGN Obes...

AIMS The impact of a high-fat diet on the failing heart is unclear, and the differences between polyunsaturated fatty acids (PUFA) and saturated fat have not been assessed. Here, we compared a standard low-fat diet to high-fat diets enriched with either saturated fat (palmitate and stearate) or PUFA (linoleic and α-linolenic acids) in hamsters with genetic cardiomyopathy. METHODS AND RESULTS ...

The effects on energy balance and brown adipose tissue thermogenesis of feeding high fat diets of differing fatty acid composition have been investigated in lean and genetically obese (ob/ob) mice. Groups of mice were fed either a low fat diet or a high fat diet based on corn oil or beef tallow for 2 wk. Energy intake and body weight gain were higher in both lean and obese animals fed the high ...
