AIMS It has been shown that beer consumption is associated with alcohol craving, in contrast to wine or spirits consumption. The present study was undertaken to evaluate whether the daily volume intake of alcoholic beverages is associated with craving in patients undergoing alcohol withdrawal. METHODS A total of 158 male patients were assessed using the obsessive compulsive drinking scale (OC...

Appetite suppression is a common response to hypoxia in fish that confers significant energy savings. Yet little is known about the endocrine signals involved in the regulation of food intake during chronic hypoxia. Thus, we assessed the impact of chronic hypoxia on food intake, the expression of the potent anorexigenic signal leptin and its receptor (lepr), the mRNA levels of key hypothalamic ...

BACKGROUND Anorexia is a common symptom among cancer patients and contributes to malnutrition and strongly impinges on quality of life. Cancer-induced anorexia is thought to be caused by an inability of food intake-regulating systems in the hypothalamus to respond adequately to negative energy balance during tumour growth. Here, we show that this impaired response of food-intake control is like...

We investigated the role of the fat mass and obesity associated gene (FTO) and variants near the melanocortin-4 receptor gene (MC4R) in modulating habitual intake of total energy and macronutrients, glycemic index, glycemic load, dietary energy density, and energy from 20 food groups in adults. In a population-based sample of 756 healthy adult twin pairs, we studied associations between FTO rs9...

Some anti-inflammatory medications reduce alcohol consumption in rodent models. Inhibition of phosphodiesterases (PDE) increases cAMP and reduces inflammatory signaling. Rolipram, an inhibitor of PDE4, markedly reduced ethanol intake and preference in mice and reduced ethanol seeking and consumption in alcohol-preferring fawn-hooded rats (Hu et al., 2011; Wen et al., 2012). To determine if thes...

OBJECTIVE Considering the controversial data regarding the role of the brain renin-angiotensin system (RAS) on the thirst and sodium appetite in ovariectomised rats, we aimed to evaluate the role of the brain angiotensin II (Ang II) AT1-receptor on the nocturnal fluids intake. MATERIALS AND METHODS Groups of Wistar female rats were ovariectomised and chronically given oestrogen or vehicle to ...

The regulation of feeding behaviour is a complex process controlled by neural circuits in the brain. In addition to neurons, genetic and pharmacological studies animal models are revealing that glia, including astrocytes, important components these circuits. This review incorporates latest evidence (published since 2019) from different brain regions for contribution astrocytes regulating contro...

The intestinal fatty acid binding protein (FABP2) is involved in lipid metabolism whereby variations in the promoter (haplotypes A/B) and exon 2 (Ala54Thr) are associated with dyslipidemia and insulin resistance. To elucidate which factors determine FABP2 expression in human mucosa, we investigated the association between fat intake, genotypes, biochemical variables, and FABP2 expression. FABP2...

Modern methods of selection have contributed greatly to the genetically superior high yielding animals of current animal production systems [1]. While this being the case of the developed world, animal production in the tropics is constrained by the everlasting deficit in feed supply [2]. Therefore, a method based on lower feed intake without affecting mature weight and production will have a g...

We tested the hypothesis that changes in sodium intake modulate adipose-tissue renin-angiotensin and natriuretic peptide system gene expression in humans. We studied 9 healthy young men in a metabolic ward at constant room temperature, humidity, and water, potassium, and calcium intake. Subjects were submitted to 4 different periods of sodium intake, and blood samples, microdialysis samples (in...
