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...

BACKGROUND Disturbances of the in utero environment may "program" for disease in later life. In this study, we determined whether dietary fat supplementation and/or diabetes in pregnancy can adversely affect vascular function in the offspring. METHODS AND RESULTS Female Sprague-Dawley rats were fed a breeding diet or a diet high in saturated fat (30% wt/wt) for 10 days before mating, througho...

Physi~l. 221(l): 376-381. 197 1 .-Within 2-4 days after birth, there was a marked depletion of cr-amylase and chymotrypsinogen in the rat pancreas. During the period 14-2 1 days, a-amylase, lipase, trypsins, and chymotrypsi...

Puberty in mammalian species is a period of rapid interactive endocrine and morphological changes. Therefore, it is not surprising that exposure to a variety of pharmaceutical and environmental compounds has been shown to dramatically alter pubertal development. This concern was recognized by the Endocrine Disrupter Screening and Testing Advisory Committee (EDSTAC) that acknowledged the need fo...

We have previously reported that weanling rats fed a 20% wheat gluten diet, limiting in lysine and containing no detectable carnitine, have significantly lower levels of carnitine in skeletal and heart muscle than rats receiving adequate dietary lysine. Rats on 20% wheat gluten diets were administered appropriate levels of DL-[6-i*C]lysine, L-[mefhyZ3H]methionine, t-N-[mefhyZ-3H]trimethyl-L-lys...

Previous studies have demonstrated that weanling rats fed AIN-93G semi-purified diets supplemented with 10% whole blueberry (BB) powder for two weeks beginning on postnatal day 21 (PND21) significantly increased bone formation at PND35. However, the minimal level of dietary BB needed to produce these effects is, as yet, unknown. The current study examined the effects of three different levels o...

Effects of 1,1-diphenyl-3-piperidinobutanol hydrochloride (Aspaminol), a nonspecific smooth muscle relaxant, on the uptake of calcium in the synaptosomes of rat brain were studied, using two stimuli i.e. high KCl and ATP. We also studied the effect of Aspaminol on the analgesic response of rat hindpaw using the Randall-Sellito test. The addition of Aspaminol inhibited the stimuli-induced calciu...

The pathogenesis of human type 1 diabetes, characterized by immune-mediated damage of insulin-producing β-cells of pancreatic islets, may involve viral infection. Essential components of the innate immune antiviral response, including type I interferon (IFN) and IFN receptor-mediated signaling pathways, are candidates for determining susceptibility to human type 1 diabetes. Numerous aspects of ...

Intrauterine growth restriction (IUGR) programs adult disease, including obesity and insulin resistance. Our group previously demonstrated that IUGR dysregulates adipose deposition in male, but not female, weanling rats. Dysregulated adipose deposition is often accompanied by the release of proinflammatory signaling molecules, such as tumor necrosis factor alpha (TNF α ). TNF α contributes to a...

A full-length cDNA clone encoding a purified augmenter of liver regeneration (ALR) factor prepared from the cytosol of weanling rat livers was isolated. The 1.2-kb cDNA included a 299-bp 5' untranslated region, a 375-bp coding region, and a 550-bp 3' untranslated region. It encoded a protein consisting of 125 amino acids. The molecular weight of ALR calculated from the cDNA was 15,081, which is...
