Melanin-concentrating hormone (MCH) is a cyclic amino acid neuropeptide localized in the lateral hypothalamus. Although MCH is thought to be an important regulator of feeding behavior, the involvement of this peptide in body weight control has been still unclear. To examine the role of MCH in development of obesity, we assessed the effect of chronic intracerebroventricular (ICV) infusion of MCH...

Sub-populations of neurons producing melanin-concentrating hormone (MCH) are characterized by distinct projection patterns, birthdates and CART/NK3 expression in rat. Evidence for such sub-populations has not been reported in other species. However, given that genetically engineered mouse lines are now commonly used as experimental models, a better characterization of the anatomy and morphofunc...

Neurons that synthesize melanin-concentrating hormone (MCH) may modulate arousal and energy homeostasis. The scattered MCH neurons have been difficult to study, as they have no defining morphological characteristics. We have developed a viral approach with AAV for selective long-term reporter gene (GFP) expression in MCH neurons, allowing the study of their cellular physiology in hypothalamic s...

PURPOSE To evaluate whether the receptors for melanin-concentrating hormone (MCH) and its functional antagonist alpha-melanocyte-stimulating hormone (alpha-MSH) are expressed in the ciliary epithelium. Furthermore, to examine whether MCH, a neuropeptide involved in fluid and electrolyte homeostasis, may influence ion flux mediated by Na,K (adenosine triphosphatase)-ATPase in a ciliary epithelia...

Microfibrillar collagen hemostat (MCH) is accepted as an effective topical hemostatic agent during endoscopic endonasal transsphenoidal surgery (EETS), particularly to achieve venous hemostasis; however, handling MCH may be troublesome because of its adherence to gloves and instruments. We describe here a method of "injection" of MCH suspension using a syringe applicator. This technique allows ...

We evaluated whether circulating levels of melanin-concentrating hormone (MCH), agouti-related protein (AGRP), and -MSH could serve as useful markers of energy homeostasis in humans. We first assessed correlations of serum MCH, AGRP, and -MSH with anthropometric, dietary, and hormonal variables in a cross-sectional study of 108 healthy humans. We then performed interventional studies to evaluat...

Melanin-concentrating hormone (MCH) and α-melanocyte-stimulating hormone (α-MSH) demonstrate opposite actions on skin coloration in teleost fish. Both peptides are present in the mammalian brain, although their specific physiological roles remain largely unknown. In this study, we examined the interactions between MCH and α-MSH after intracerebroventricular administration in rats. MCH increased...

PURPOSE To assess motivation to change (Mch) of patients with an eating disorder (ED) and its relationship with quality-of-life (QoL) by comparing patient and psychiatrist perceptions. METHOD Patients (n=358) with an ED completed the disease-specific Health-Related Quality of Life for Eating Disorders (HeRQoLED) questionnaire, the Eating Attitudes Test (EAT-26) and the Short-Form Health Surve...

Mozambique continues to face many challenges in HIV and maternal and child health care (MCH). Community-based antiretroviral treatment groups (CAG) enhance retention to care among members, but whether such benefits extend to their families and to MCH remains unclear. In 2011 we studied utilization of HIV and MCH services among CAG members and their family aggregates in Changara, Mozambique, thr...

Melanin-concentrating hormone (MCH) has been reported to be involved in the regulation of feeding behaviour in rats and mice. Because many neuropeptides that influence ingestive behaviour also regulate reproductive function, the present study was designed to determine if central administration of MCH changes pulsatile secretion of luteinizing hormone (LH) in the rats. Wistar-Imamichi strain fem...
