A Slow-Digesting Carbohydrate Diet during Rat Pregnancy Protects Offspring from Non-Alcoholic Fatty Liver Disease Risk through the Modulation of the Carbohydrate-Response Element and Sterol Regulatory Element Binding Proteins.

High-fat (HF) and rapid digestive (RD) carbohydrate diets during pregnancy promote excessive adipogenesis in offspring. This effect can be corrected by diets with similar glycemic loads, but low rates of carbohydrate digestion. However, the effects of these diets on metabolic programming in the livers of offspring, and the liver metabolism contributions to adipogenesis, remain to be addressed.

Maternal Dietary Supplementation with Oligofructose-Enriched Inulin in Gestating/Lactating Rats Preserves Maternal Bone and Improves Bone Microarchitecture in Their Offspring.

Nutrition during pregnancy and lactation could exert a key role not only on maternal bone, but also could influence the skeletal development of the offspring. This study was performed in rats to assess the relationship between maternal dietary intake of prebiotic oligofructose-enriched inulin and its role in bone turnover during gestation and lactation, as well as its effect on offspring peak bone mass/architecture during early adulthood. Rat dams were fed either with standard rodent diet (CC group), calcium-fortified diet (Ca group), or prebiotic oligofructose-enriched inulin supplemented diet (Pre group), during the second half of gestation and lactation.

Contribution of polyunsaturated fatty acids to intestinal repair in protein-energy malnutrition.

The aim of this study was to assess the effect of polyunsaturated fatty acids supplied in the diet on intestinal mucosa repair in a rat model of protein-energy malnutrition. Rats were fed either a standard semipurified diet or the same diet containing lactose as the only source of carbohydrate to cause protein-energy malnutrition. Diarrhea was induced within 24 h and was maintained for 2 weeks, after which both groups of rats were fed for 1 week either the standard diet or the standard diet supplemented with different sources of fatty acids, such as olive oil (OO), fish oil (FO), and purified phospholipids from pig brain (BPL).

Dietary nucleotides modulate mitochondrial function of intestinal mucosa in weanling rats with chronic diarrhea.

Background: Chronic diarrhea during early infancy is characterized by intestinal mucosal injury, and as a consequence, the mitochondrial system of oxidation and reduction and energy production is altered. Since dietary nucleotides have been associated with the process of intestinal mucosal repair in rats with chronic diarrhea, the aim of this study was to examine the effects of dietary nucleotides on the functioning of mucosal mitochondria.

Methods: Weanling rats were fed with a semipurified synthetic diet (C) or the same diet in which carbohydrates were substituted by lactose (L), resulting in chronic diarrhea.

Proliferation, functionality, and extracellular matrix production of hepatocytes and a liver stellate cell line: a comparison between single cultures and cocultures.

Hepatic fibrosis is a common feature of many chronic liver diseases. Given the ethical considerations of studies with humans and the limited availability of liver biopsies, there is a need for in vitro models to understand the molecular events involved in hepatic fibrosis. The aim of this work was to compare the behavior of two hepatic cell types involved in fibrogenesis: a liver stellate cell line (CFSC-2G) and primary hepatocytes, both in single and mixed cultures.
