Growth hormone (GH) secretion by the pituitary is regulated by stimulatory and inhibitory pathways such as growth hormone releasing hormone (GHRH) and somatostatin, respectively, being also modulated by different neurotransmitters acting at the hypothalamic/pituitary level. The pineal gland hormone melatonin regulates GH secretion in many mammals, including humans, although its role in modulating GH secretion has been debated. We describe the case of a young woman chronically taking melatonin for sleep disturbances, referring to her general practitioner for flushing that appeared just after starting melatonin intake.

Background: We investigated factors associated with post-transplant growth in pediatric kidney transplant (KTx) recipients with a focus on plasma bicarbonate (HCO3) and estimated the effect of alkali treatment on growth.
Methods: In this study of the CERTAIN Registry, data were collected up to 5 years post-transplant. Generalized Additive Mixed Models were applied to assess the association between post-transplant growth and covariates.

Acromegaly is a rare endocrine disorder caused by excessive growth hormone (GH) production, due, in the vast majority of cases, to the presence of a GH-secreting pituitary tumour. The chronic elevation of GH and the resulting high circulating levels of insulin-like growth factor-1 (IGF-1) cause the characteristic tissue overgrowth and a number of associated comorbidities, including several metabolic changes, such as glucose intolerance and overt diabetes mellitus (DM). Elevated GH concentrations directly attenuate insulin signalling and stimulate lipolysis, decreasing glucose uptake in peripheral tissues, thus leading to the development of impaired glucose tolerance and DM.

The cation-proton antiporter (CPA) superfamily plays pivotal roles in regulating cellular ion and pH homeostasis in plants. To date, the regulatory functions of CPA family members in rice (Oryza sativa L.) have not been elucidated.

Background: As a state of metabolic and nutritional derangements, protein-energy wasting (PEW) is highly prevalent and associated with increased morbidity and mortality in hemodialysis patients. Fibroblast growth factor-23 (FGF-23) and Klotho have been proven to contribute to chronic kidney disease-mineral and bone disorder (CKD-MBD) in patients undergoing hemodialysis. Previous evidence suggested that FGF-23 and Klotho may also contribute to the malnutritional status among these patients; however, the inter-relationship between the FGF-23-Klotho axis and PEW remains unclear.
