Central nervous system (CNS) receives peripheral relevant information that are able to regulate individual's energy balance through metabolic, neural, and endocrine signals. Ingested nutrients come into contact with multiple sites in the gastrointestinal tract that have the potential to alter peptide and neural signaling. There is a strong relationship between CNS and those peripheral signals (...

The gastrointestinal endocrine cells are essential for life. They regulate the gastrointestinal motility, secretion, visceral sensitivity, absorption, local immune defense, cell proliferation and appetite. These cells act as sensory cells with specialized microvilli that project into the lumen that sense the gut contents (mostly nutrients and/or bacteria byproducts), and respond to luminal stim...

Hormones produced by the adrenal glands and adipose tissues have important roles in normal physiology and are altered in many disease states. Obesity is associated with changes in adrenal function, including increase in adrenal medullary catecholamine output, alterations of the hypothalamic-pituitary-adrenal (HPA) axis, elevations in circulating aldosterone together with changes in adipose tiss...

Adipokines are a large group of polypeptide hormones secreted by white adipose tissue able to interact through different receptors with several organs, including liver, central nervous system and gonads. In this review, we will focus on the adipokines that mediate their effects G protein-coupled receptors, namely apelin chemerin. Firstly, review structure (APJ for apelin, CMKLR1, GPR1 CCRL2 che...

Given the fundamental role of sex hormones in the regulation of body composition and homeostasis, in humans, more emphasis should be placed on the potential role of androgen dysregulation in the pathophysiology of different obesity phenotypes and the metabolic syndrome (MetS). Physicians must be mindful to evaluate MetS in all men diagnosed with hypogonadism and hypogonadism in all men diagnose...

Sex Hormones and Carotid Atherosclerosis in the Metabolic Syndrome To the Editor: We read with great interest the recent article by Dr Iglseder et al1 dealing with sex differences in early carotid atherosclerosis in the metabolic syndrome. The results of their study demonstrated that extent of plaques and cariotid artery intima-media thickness parameters were significantly higher in subjects wi...

Key external stakeholders: Dairy and beef farmers, Irish Cattle Breeding Federation (IC scientists. Practical implications for stakeholders: This study showed that IGF-1 has potential as a predictor of well documented association with a number of reproductiv weeks postpartum for IGF-1 could help identify cows that are balance, thereby providing valuable additional information fo for improved pr...

Although the phenotype of T-cell senescence has been extensively investigated, few studies have analyzed the factors that promote the generation and maintenance of naïve and memory T cells that exist throughout the lifespan of the individuals. Unlike senescent T cells, naïve and memory T cells are able to participate in useful immune responses as well as respond to new activation. Hormones such...

PURPOSE OF REVIEW The article is principally intended to describe the recent evolutions in the field of research concerned with the metabolic actions of thyroid hormones and those of some of their metabolites or derivatives. Mitochondria, as a result of their functions, represent the principal objective of scientists investigating the mechanisms underlying the effects of thyroid hormones or the...
