OBJECTIVE Association between prostate cancer and obesity remains controversial. Allelic deletions of PTEN, a tumor suppressor gene, are common in prostate cancer in men. Monoallelic Pten deletion in mice causes low prostatic intraepithelial neoplasia (mPIN). This study tested the effect of a hypercaloric diet on prostate cancer in Pten (+/-) mice. METHODS 1-month old mice were fed a high-cal...

BACKGROUND Despite their energy density, walnuts can be included in the diet without adverse effects on weight or body composition. The effect of habitual walnut intake on total calorie intake is not well studied. Effects on overall diet quality have not been reported. METHODS Randomized, controlled, modified Latin square parallel design study with 2 treatment arms. The 112 participants were ...

BACKGROUND Diet-induced weight reduction promotes a decrease in resting energy expenditure that could partly explain the difficulty in maintaining reduced body mass. Whether this reduction remains after stabilized weight loss is still controversial, and the molecular mechanisms are unknown. OBJECTIVE The objective was to investigate the effect of a stabilized 10% weight loss on body compositi...

CONTEXT Intrauterine growth retard (IUGR) continues to be a significant perinatology problem at the end of this century. The nature of the etiologic agent, the time when the attack occurred during pregnancy and its duration affect the type of IUGR. OBJECTIVE To study the evolution of fetal pancreas and placenta between the 18th and 21st day of pregnancy in rats submitted to maternal protein-c...

Eating a "Western diet" high in fat and sugars is associated with accelerated development of age-related metabolic diseases such as obesity, insulin resistance, and diabetes while incidences of these diseases are decreased on a low-calorie diet. The mitochondrial NAD(+)-dependent protein deacetylase SIRT3 has previously been shown to be important in adapting to metabolic stress brought on by fa...
