The central serotonergic signalling system has been shown to play an important role in appetite control and the regulation of food intake. Serotonin exerts its anorectic effects mainly through the 5-HT(1B), 5-HT(2C) and 5-HT(6) receptors and these are therefore receiving increasing attention as principal pharmacotherapeutic targets for the treatment of obesity. The 5-HT(2C) receptor has the dis...

Serotonin (5-HT), known as neuromodulator, regulates immune responses and inflammatory cascades. The expression and function of 5-HT receptors on alveolar macrophages (AM), which are the major fraction of pulmonary immune cells, remain elusive. Therefore, we determined the expression of 5-HT type 2 receptors and investigated the effects evoked by stimulation with 5-HT in AM compared with alveol...

BACKGROUND & AIMS 5-hydroxytryptamine receptor (5-HT(4)R) agonists promote gastrointestinal motility and attenuate visceral pain, but concerns about adverse reactions have restricted their availability. We tested the hypotheses that 5-HT(4) receptors are expressed in the colonic epithelium and that 5-HT(4)R agonists can act intraluminally to increase motility and reduce visceral hypersensitivit...

With data from recently available selective antagonists for the 5-HT(7) receptor, it has been hypothesized that 5-hydroxytryptamine (5-HT)-induced hypothermia is mediated by the 5-HT(7) receptor, an effect previously attributed to other receptor subtypes. It has been established that the biologically active lipid oleamide allosterically interacts with the 5-HT(7) receptor to regulate its transm...

Objectives. We compared the ultrasonography and pathology features of papillary thyroid carcinoma (PTC) in pediatric and adolescents with Hashimoto's thyroiditis (HT) with those of non-HT patients. Materials and Methods. Eleven patients who were surgically confirmed to have pediatric or adolescent PTC from 2006 to 2014 were included in this study. We retrospectively analyzed the preoperative ul...

Rheological and physicomechanical properties of epoxy binders based on ED-20 resin with isoMTHPA HT-152B (modified isoMTHPA) anhydride hardeners a binder Ethal-370 modified Ethal-450 amine hardener have been studied. The pot life the curing agents (isoMTHPA HT-152B) at 25 °С is quite high. Etal-370 Etal-450 must be preheated before use to 40-60 °C due high viscosity. highest strength 57.3 MPa w...

We studied the distribution of 5-hydroxytryptamine- (5-HT-) containing cells in the guinea pig pancreas and examined the effects of 5-HT on fluid secretion by interlobular pancreatic ducts. The 5-HT-immunoreactive cells with morphological characteristics of enterochromaffin (EC) cells were scattered throughout the duct system and were enriched in islets of Langerhans. The fluid secretory rate i...

The serotonin (5-HT) system densely innervates many brain areas and is important for proper brain development. To specifically ablate the 5-HT system we generated mutant mice carrying a floxed Munc18-1 gene and Cre recombinase driven by the 5-HT-specific serotonin reuptake transporter (SERT) promoter. The majority of mutant mice died within a few days after birth. Immunohistochemical analysis o...

Background: The removal of toxic metals from sewage and wastewaters is one of the most important concerns in the twenty first century. The removal of poisonous Cr(VI) from aqueous solution by different low-cost available nanoporous adsorbents was investigated in the present study.  Methods: Fumed silica, bentonite (BN), hydrotalcite (HT), MCM-41, Na-Y, mordenite (MOR) and SAPO-34 were ...
