BACKGROUND The infrapatellar fat pad (IPFP) has been implicated as a possible source of osteoarthritis (OA) development and knee pain due to the production of inflammatory mediators and the existence of nerve fibers within this structure. Calcitonin gene-related peptide (CGRP) is a vasodilatory neuropeptide that is localized to joint tissues and has recently been implicated in the development o...

Rat trigeminal ganglion projections to a visceral target (intracranial blood vessels) are enriched in calcitonin gene-related peptide (CGRP) and substance P (Sub P) compared to trigeminal ganglion projections to a cutaneous target (the forehead skin). We asked if transplants of a novel visceral target (fetal stomach antrum tissue) into the path of the neonatal rat trigeminal frontal nerve proje...

Levels of calcitonin gene-related peptide (CGRP), a vasodilator peptide present in nerves and airway endocrine cells of the rat respiratory tract, are increased in hypoxic lung and decreased in plasma, suggesting impaired CGRP release. We wanted to determine whether there was an adaptive functional response to reduced CGRP levels in hypoxia. Density of binding sites for CGRP were compared with ...

Objective(s):The neuropeptide calcitonin gene-related peptide (CGRP) has long been postulated to play an integral role in the pathophysiology of migraine. Earlier studies showed that CGRP can stimulate the synthesis and release of nitric oxide (NO) and cytokines from trigeminal ganglion glial cells. The purpose of this study was to determine the effect of 17β-estradiol in regulation of CGRP exp...

The neuropeptide calcitonin gene-related peptide (CGRP) is expressed by one-third of adult rat lumbar dorsal root ganglion (DRG) neurons, many of which mediate pain sensation or cause vasodilation. The factors that regulate the developmental expression of CGRP are poorly understood. Embryonic DRG neurons initially lack CGRP. When these neurons were stimulated in culture by serum or persistent 5...

genetic parameters and trends for milk and fat yields as well as for fat percentage were estimated from 35,438 milk production records (305d, 2x) of 17,971 holstein dairy cattle in 133 herds during the period of 1990-2003 in khorasan province. variance components were estimated using restricted maximum likelihood statistical method applying univariate and repeatability animal models. for the un...

objective(s) recent studies on human indicate that the introduction of therapeutic use of tolerogenic dendritic cell (dc) for chronic inflammatory conditions is imminent. for the purpose of defining cgrp potency in tolerogenic dc production, we investigated the phenotype and il-'2 production of dcs generated from the monocytes of rheumatoid arthritis (ra) patients in the presence of the ca...

The objective of this study was to investigate the effect of milking frequency (two times daily vs. three times daily) on the 305-d lactation milk, fat and protein yield and fat and protein percentage of Holstein dairy cows in Morocco. Data analyzed were 31400 records collected between 2009 and 2016 on 14272 cows raised in 194 herds. The frequency of milking had significant effects (P<...
