The mechanism and routes through which peptide tyrosine-tyrosine (PYY) exerts its anorectic effects are still largely unknown. In the present study, we investigated the roles of the area postrema (AP), subfornical organ (SFO) and vagus nerve in mediating the anorectic effect of PYY using PYY(3-36) conjugated to human serum albumin (PYY(3-36)-HSA) in rats. PYY(3-36)-HSA is a large molecule that ...

Weight gain and risk of type 2 diabetes are inversely associated with a high intake of insoluble cereal fibres. Because nutrient-induced changes of 'satiety hormones' from the gut may play a role in this process, we evaluated the effects of purified insoluble fibres on postprandial responses of plasma peptide YY (PYY), serum ghrelin and satiety as secondary outcome measures of a study investiga...

BACKGROUND PYY is an appetite suppressing hormone. Low circulating PYY has been linked to greater BMI. However data is controversial and this association has not been verified in large human populations. OBJECTIVE The purpose of this study was to investigate if fasting serum total PYY is associated with obesity status and/or adiposity at the population level. DESIGN A total of 2094 subjects...

Peptide YY3-36 [PYY(3-36)], a gastrointestinal peptide that is released into the circulation in response to ingesting a meal, has recently been suggested to play a role in controlling food intake. PYY(3-36) has been reported to inhibit food intake following peripheral administration in rodents and in human subjects. To more fully characterize the potential feeding actions of PYY(3-36), we exami...

objective to determine the changes in thyroid function tests in children who underwent antiepileptic therapy in shahid beheshti hospital, kashan, in 2008. materials & methods this analytical-observational study was carried out in a cohort fashion without an external control group (self controlled) on 45 children with new onset epilepsy who had not been previously treated with antiepileptic medi...

BACKGROUND & OBJECTIVES Small intestinal bacterial overgrowth (SIBO) due to ileal brake-induced hypomotility may cause tropical sprue (TS). We evaluated effect of infusion of fat or placebo in duodenum randomly in patients with TS and healthy controls on antroduodenal manometry (ADM) and mediators of ileal brake, and duodenocaecal transit time (DCTT). METHODS ADM and DCTT (lactulose hydrogen ...

We investigated the effect of acarbose, an alpha-glucosidase and pancreatic alpha-amylase inhibitor, on gastric emptying of solid meals of varying nutrient composition and plasma responses of gut hormones. Gastric emptying was determined with scintigraphy in healthy subjects, and all studies were performed with and without 100 mg of acarbose, in random order, at least 1 wk apart. Acarbose did n...

Background: To investigate the expression of TNF-α, IL-6, IL-10 in the plasma of patients with lung cancer who received radiation therapy (RT), and to analyze the correlation between these cytokines and radiation pneumonitis (RP). Materials and Methods: Patients with lung cancer who received 3D-CRT in our hospital were prospectively evaluated. Circulating cytokine levels were measured wit...
