Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders
Andrology, EarlyView.Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...

In ovo Administration of Ghrelin and Subsequent Prolactin Level in Newly Hatched Chicks
The Journal of Poultry Science, 2011 Ghrelin is a prolactin (PRL)-releasing factor in animal species. The aim of this study was to investigate the effects of in ovo ghrelin administration on plasma PRL levels in hatched chicks. We divided 350 fertilized eggs into 7 groups: group T1 as the

Clinical Obesity, Volume 15, Issue 2, April 2025.Summary Background Bariatric surgery is very effective in long‐term weight management. The present study was undertaken to investigate the short‐term effects of sleeve gastrectomy (SG) and of Roux‐en‐Y gastric bypass (RYGB) on (a) gastrointestinal (GI) motility, that is gastric emptying and oro‐cecal transit time and (b) secretion of regulatory gut ...

Clinical Obesity, Volume 15, Issue 2, April 2025.Summary Chronic stress, characterized by increased long‐term exposure to the glucocorticoid hormone cortisol, is increasingly linked to obesity development. Still, various knowledge gaps persist, including on underlying pathophysiological mechanisms. The aim of the current review is to provide the latest insights on the connection between stress and ...

Effects of sodium octanoate, acylated ghrelin, and desacylated ghrelin on the growth of genetically engineered escherichia coli [PDF]
Journal of Medical Biochemistry, 2011 Acylated ghrelin is a 28-amino acid peptide hormone bearing a fatty acid group based on octanoic acid (caprylic acid) at the serine which is located at position 3 and at the N-terminus.

A signal transduction blind spot: the function of adenylyl cyclase transmembrane domains
The FEBS Journal, EarlyView.Transmembrane adenylyl cyclases (tmACs) are essential for synthesising the universal second messenger cyclic AMP. All tmACs share a common topology that includes a large 12‐helix transmembrane (TM) domain. This domain accounts for ~ 35% of the coding sequence but its function is still an open question.

Controversies in NEN: An ENETS position statement on nutritional support in neuroendocrine neoplasms
Journal of Neuroendocrinology, EarlyView.Abstract Neuroendocrine neoplasms (NEN) themselves and also their treatment may cause malnutrition, inducing changes in physiological behaviour and eventually leading to increased rates of morbidity and mortality. Malnutrition is a common, under‐recognised and under‐treated condition in patients with NEN, and there are limited data available on the ...
