We have characterized the structure of the chicken corticotropin-releasing factor (CRF) gene through cDNA cloning and genomic sequence analysis, and we analyzed the expression of CRF mRNA and peptide in the diencephalon of the chick throughout embryonic development. The structure of the chicken CRF gene is similar to other vertebrate CRF genes and contains two exons and a single intron. The pri...
The corticotropin-releasing factor (CRF) system plays a key role in a diversity of behaviors accompanying stress, anxiety and depression. There is also substantial research on relationships between social behaviors and the CRF system in a variety of taxa including fish, birds, rodents, and primates. Some of these relationships are due to the broad role of CRF and urocortins in stress and anxiet...
Background: Nonalcoholic fatty liver disease (NAFLD) occurs when more than 5% of fat accumulates in the parenchyma without excess alcohol consumption. The objective this study is to investigated association between cardiorespiratory fitness (CRF), muscle strength (MS), and NAFLD. Methods: subjects were 1325 males aged 40–50 who had visited National Fitness Center located Republic Korea from 201...
CRF is the main component in the brain neuropeptide effector system responsible for the behavioral, endocrine, and physiological activation that accompanies stress activation. Reduced CRF system activation plays a role in the etiology of a variety of psychiatric and metabolic disease states. We have developed a novel protein conjugate that joins native rat/human CRF to a ribosome-inactivating p...
This study tested the hypothesis that endogenous glucocorticoids regulate a putative neurotransmitter function of corticotropin-releasing factor (CRF) in the locus coeruleus (LC). LC spontaneous discharge and activation by intracerebroventricularly administered CRF, hypotensive challenge, sciatic nerve stimulation, and carbachol were compared in adrenalectomized and sham-operated halothane-anes...
Corticotropin-releasing factor (CRF) plays important physiological functions in the central nervous system. The present study was performed to investigate the role of CRF and CRF receptor in nociceptive modulation in the central nucleus of amygdala (CeA) of rats. The hindpaw withdrawal latency (HWL) to noxious thermal and mechanical stimulation increased significantly after intra-CeA administra...
Corticotropin-releasing factor (CRF) is a 41-amino acid peptide with distinct effects on gastrointestinal motility involving both CRF-1 and CRF-2 receptor-mediated mechanisms that are generally claimed to be centrally mediated. Evidence for a direct peripheral effect is rather limited. Electrophysiological studies showed a cAMP-dependent prolonged depolarization of guinea pig myenteric neurons ...
Two subtypes of the corticotropin-releasing factor (CRF) receptor, CRF(1) and CRF(2), differentially modulate brain functions such as anxiety and memory. To facilitate the analysis of their differential involvement, we developed a CRF(1)-specific peptidic agonist by synthesis of chimeric peptides derived from human/rat CRF, ovine CRF (oCRF), and sauvagine (Svg). High affinity to the CRF-binding...
We present LS-CRF, a new method for training cyclic Conditional Random Fields (CRFs) from large datasets that is inspired by classical closed-form expressions for the maximum likelihood parameters of a generative graphical model with tree topology. Training a CRF with LS-CRF requires only solving a set of independent regression problems, each of which can be solved efficiently in closed form or...
International guidelines recommend specific interventions to reduce cancer-related fatigue (CRF). Evidence suggests underutilization of these among breast cancer survivors. The QualFatigue study aimed explore the potential factors influencing use interventions, for relief, in patients with CRF through qualitative analyses. Patients stage I–III cancer, and ≥4 on a 10-point numerical scale were r...
