OBJECTIVE
Vitamin A and its metabolites are known to regulate lipid metabolism. However so far, no study has assessed, whether vitamin A deficiency per se aggravates or attenuates the development of non-alcoholic fatty liver disease (NAFLD). Therefore, here, we tested the impact of vitamin A
BACKGROUND
Vitamin A deficiency can result from malnutrition, malabsorption of vitamin A, impaired vitamin metabolism associated with liver disease, or chronic debilitating diseases like HIV infection or cancer.
OBJECTIVE
Cannabis administration has been described as a palliative symptom management
Vitamin A deficiency has a widespread occurrence globally and is considered as one of the world's most serious health risk factors. Potential solutions to address this deficiency include dietary diversification or supplementation, but food fortification is generally accepted as the most
Stearoyl-CoA desaturase 1 (SCD1) is a key lipogenic enzyme responsible for endogenous synthesis of monounsaturated fatty acids (MUFA) and plays a key role in various pathophysiology, including fatty liver diseases. In this experimental study the impact of vitamin A deficiency was Here, we tested a hypothesis that vitamin A and/or its metabolic pathways are involved in the high-fructose-mediated alteration in adipose tissue biology. For this purpose, weanling male Wistar rats were provided with one of the following diets: control (C), control with vitamin A deficiency
Antioxidants are known to reduce cardiovascular disease by reducing the concentration of free radicals in the vessel wall and by preventing the oxidative modification of low-density lipoproteins. The prooxidative effect of a vitamin-A-deficient diet on the aorta has previously been demonstrated by
We reviewed the initial lipid and fat-soluble vitamin levels in 56 patients with primary sclerosing cholangitis (PSC) enrolled in a randomized, placebo-controlled trial evaluating ursodeoxycholic acid. We also evaluated lipid and vitamin levels in a group of 87 patients with advanced PSC being
Cardiovascular disease (CVD) risk factors, such as bad eating habits, are typical in adolescence and lead to the consumption of meals that are not always sufficient in vitamins A, E, β-carotene, excess calories and elevated serum leptin levels. The purpose of this research is to study
Dietary lipids have been shown to increase bioavailability of provitamin A carotenoids from a single meal, but the effects of dietary lipids on conversion to vitamin A during absorption are essentially unknown. Based on previous animal studies, we hypothesized that the consumption of provitamin A
Among more than 50 provitamin carotenoids, beta-carotene is the most metabolically active source of retinol. Despite diets rich in fruits and vegetables containing beta-carotene, vitamin A deficiency is the leading cause of blindness and childhood mortality in developing countries. In addition, the
Measurements of nutritionally relevant biochemical and endocrine variables were made on 60 apparently healthy children (group A) whose parents suffered from leprosy and who had been separated at the age of 4 years and brought up in preventoria. Most of the measurements were also made on a comparison
The purpose of this study was to determine the blood levels of selected nutritional status indicators and the dietary intake of Costa Rican Cabécar Indians aged 10 to 16 years. The results showed that 65% of the adolescents had an adequate body mass index (BMI) for their age, and 32% had a BMI < 5th
BACKGROUND
Epidemiological findings have shown the rise of the prevalence of obesity in several segments of the world population, and more recent evidences point to a possible association with vitamin A deficiency (VAD). The aim of this study was to investigate vitamin A nutritional status in
Fatty acid metabolism in liver and skeletal muscle has been studied in rats treated with high doses of vitamin A and in those made vitamin A-deficient. Ingestion of 30,000 IU of vitamin A for two days resulted in increased incorporation of palmitate-1-14C into triglycerides but not into
Here, we present the expression data on various metabolic pathways of liver with special emphasize on lipid and carbohydrate metabolism and long chain polyunsaturated fatty acid (PUFA) synthesis, both at gene and protein levels. The data were obtained to understand the effect of vitamin A deficiency
