Background Food selection and ingestion both in humans rodents, often is a critical factor determining excess energy intake its related disorders. Methods Two different concepts of high-fat diets were tested for their obesogenic effects rats; cases, lipids constituted about 40% intake. The main difference with controls fed standard lab chow, was, precisely, the lipid content. Cafeteria (K) self-selected devised to be desirable rats, mainly because diverse mix tastes, particularly salty...

Background and Objectives. Glucose, an aldose, spontaneously reacts with protein amino acids yielding glycosylated proteins. The compounds may reorganize to produce advanced glycosylation products, which regulatory importance is increasingly being recognized. Protein produced without the direct intervention of enzymes results in loss function. Glycosylated plasma albumin, haemoglobin are currently used as index mean glucose levels, since higher availability rates. In this study we intended...

Liver amino acid metabolism decreased with cafeteria diet through lower ammonium production (even in females) and urea cycle activity.

Nitrogen balance studies have shown that a portion of the N ingested but not excreted is accounted for. We compared several diets (standard, high-fat, high-protein, and self-selected cafeteria) to determine how diet-dependent energy sources affect nitrogen handling, i.e., liver urea cycle. Diet components rat homogenates were used for nitrogen, lipid, analyses. Plasma individual amino acids, as well cycle enzyme activities, determined. Despite ample differences in intake, circulating acids...

Background: Glucose is the main inter-organ energy supplying metabolite in humans and other vertebrates. In clinical analyses, its measurement probably most performed used for diagnostic, monitoring control of physiological status. However, glucose chemical structure, specially anomeric forms (alpha/beta), may deeply interfere their own often resulting misleading results. Methods: These effects on estimation were studied by using a common oxidase/peroxidase based method, presence or absence...

Abstract The ingestion of excess lipids often produces the accumulation liver fat. modulation diet energy partition affects this process and other metabolic responses, oestrogens androgens are implied in process. Ten-week-old male female rats were fed with either standard rat chow (SD), SD enriched coconut oil (high-fat diet, HF), protein (high-protein HP) or a ‘cafeteria’ (CAF) for 1 month. HF CAF diets provided same lipid-derived percentage (40 %), HP derived was twice %) that SD. Animals...

The relative proportions between nutrients affects the fate of them for metabolic interconversion, storage and turnover or, essentially energy, in a process partition modulated by hormonal factors. A basic common chow model was used: ST or standard diet, HF high-fat HP high-protein had substrate. CF cafeteria-type diet added comparison. Rats (female male) received 30d. Nutrient intake body composition were measured. Plasma glucose, lactate, testosterone (T) estradiol (E2) Common groups...

Scope Eating large amounts of fat is usually associated with accumulation. However, different types diets (not only lipids) elicit metabolic responses. Methods and results Male female rats (10 week‐old) are distributed in four groups fed for 1 month a standard diet (SD), or this enriched either lipid (high‐fat diet, HF) protein (high‐protein HP), cafeteria (CAF). Both HF CAF share the percentage energy from lipids (40%) but these different. Protein‐derived HP also 40%. Feeding SD, HF, does...

<p>The ingestion of excess fat often produces an increased body weight, because higher adiposity and accumulation in the liver. However, modulation diet energy partition may affect differently metabolic responses extent lipid deposition.
