The roles of vasoactive intestinal polypeptide in circadian entrainment of suprachiasmatic nucleus
… ambient cues to generate coherent daily rhythms. Vasoactive intestinal polypeptide: VIP), a neuropeptide produced by SCN neurons, plays a major role in synchronizing SCN neurons to each other. Whether VIP mediates synchrony to environmental cues and how synchrony within the SCN is achieved has not …

Regulation of Neuropeptide Y, Vasoactive Intestinal Polypeptide, and Their Receptors in Trigeminal Ganglion Neurons and Glia in Response to Adjuvant-Induced Inflammation
… and pain transmission. Neuropeptide Y (NPY), vasoactive intestinal polypeptide (VIP), and their receptors have been implicated in the underlying pathology of temporomandibular joint disorders. The goal of this study was to investigate activation of NPY, VIP, and their receptors in a model of …

Regulation of duodenal mucosal bicarbonate secretion
… dibutyryl 3' ,5'-cyclic adenosine monophosphate, vasoactive intestinal polypeptide, prostaglandin E2, carbachol and theophylline are the chief agonists of duodenal bicarbonate secretion. Vasoactive intestinal polypeptide and prostaglandin E2 act directly via distinct receptors on the duodenal …

Innervation des Cervidenhodens
… The cervine testis contains a little amount of Vasoactive Intestinal Polypeptide (VIP)-positiv axons which reach the caudal pole of testis as parts of the inferior spermatic nerve and via lig. testis proprium. The nerve density in the interior of the testicular lobules shows no regional …

Interactions of islet hormones with acetylcholine and cholecystokinin-octapeptide in the isolated pancreas of normal and diabetic rats
… investigates the effects of the neuropeptides, vasoactive intestinal polypeptide (VIP) and galanin, the islet hormones insulin, glucagon and somatostatin, the neurotransmitter acetyicholine (ACh), the gut hormone cholecystokinin octapeptide (CCK-8), sodium nitroprusside (SNIP), 8-Bromo guanosine …

Hypothalamic Mechanisms of Food Intake in Birds
… injection including gastrin releasing peptide, vasoactive intestinal polypeptide, neuropeptide AF, and prostaglandin D2. Additionally, I explored the effects of HAT on food intake, and on the efficacy of several ICV administered appetite associated factors including neuropeptide Y, corticotropin …

Neuroendocrine regulation of broodiness in the domestic hen
… action of the hypothalamic neuropeptide, vasoactive intestinal polypeptide (VIP). The aim of this study was to increase understanding and knowledge of the interactions between these hormones and neuropeptide in the neuroendocrine control of incubation behaviour in the domestic hen. …

Biphasic neurogenic vasodilatation in the bovine intraocular long posterior ciliary artery
… candidates including substance P, vasoactive intestinal polypeptide (VIP) and adenosine triphosphate (ATP) were investigated, but there was no convincing evidence to suggest that they play a role in mediating the second component of neurogenic vasodilatation. 6.As the transmitter …

Distribution of neuropeptides and neurotransmitters and their effects on insulin and glucagon secretion in normal and diabetic rat pancreas
… (GLU), somatostatin (SUM) and pancreatic polypeptide (PP). The prime aim in the management of diabetes is to increase insulin secretion and to improve its action. Bioactive substances that can perform this function are important in the control of this disease. Too little information is …

Central mechanisms involved in the reproductive cycle of the ring dove (Streptopelia Risoria)
… thought to be involved. Finally, the role of vasoactive intestinal polypeptide (VIP) in the breeding cycle of the ring dove was investigated. Hypothalamic VIP is the releasing factor responsible for an increased concentration of prolactin in the ring dove during incubation. It is possible that …
