Introduction: Heart secretes hormones such as natriuretic peptide. The purpose of this study was to investigate the effects of 12 weeks of resistance training on these hormones. Methods: Twenty four healthy men (Mean age ± SD: 24.9 ± 3.2 years) were randomly allocated to experimental and control groups. Subjects in the experimental group performed a 12-week resistance training program, 3 ses...

Obesity has received much attention worldwide in association with an increased risk of cardiovascular diseases, diabetes, and cancer. At present, bariatric surgery is the only effective treatment for obesity in which long-term weight loss is achieved in patients. By contrast, pharmacological interventions for obesity are usually followed by weight regain. Although the exact mechanisms of long-t...

Chemical derivatives of the gut-derived peptide hormone glucagon-like peptide 1 (GLP-1) are among the best-in-class pharmacotherapies to treat obesity and type 2 diabetes. However, GLP-1 analogs have modest weight lowering capacity, in the range of 5-10%, and the therapeutic window is hampered by dose-dependent side effects. Over the last few years, a new concept has emerged: combining the bene...

Knowledge about the relationship between exercise and appetite is important both for athletes wishing to optimise performance and for those interested in maintaining a healthy body weight. A variety of hormones are involved in appetite regulation including both episodic hormones, which are responsive to episodes of feeding, and tonic hormones, which are important regulators of energy storage ov...

Glucose metabolism is tightly controlled by multiple hormones and neurotransmitters in response to nutritional, environmental, and emotional changes. In addition to insulin and glucagon produced by pancreatic islets, two incretin hormones, namely glucagon-like peptide-1 (GLP-1) and gastric inhibitory polypeptide (GIP, also known as glucose-dependent insulinotropic peptide), also play important ...

By the end of this section, you will be able to: • Explain the interrelationships of the anatomy and functions of the hypothalamus and the posterior and anterior lobes of the pituitary gland • Identify the two hormones released from the posterior pituitary, their target cells, and their principal actions • Identify the six hormones produced by the anterior lobe of the pituitary gland, their tar...

SYNOPSIS. Integumental color changes and eye pigment movements in crustaceans are regulated by pigmentary-effector hormones. The identified hormones include: an octapeptide RPCH (red pigment-concentrating hormone) and several forms of octadecapeptide PDH (pigment-dispersing hormone: a-PDH, b-PDH). RPCH-related peptides (AKHs, adipokinetic hormones) and PDH-related peptides (PDFs, pigment-disper...

Gastrointestinal (GI) peptide hormones, ghrelin (GHRL), cholecystokinin (CCK), and peptide YY (PYY) genes were identified in Atlantic salmon, Salmo salar. Full-length cDNAs encoding two isoforms of GHRL (GHRL-1 and GHRL-2), two isoforms of CCK (CCK-L and CCK-N) and peptide YY (PYY) cDNA were obtained. The GHRL-1 and GHRL-2 genes encoded proteins of 111- and 108-amino acids, respectively. Both t...
