OBJECTIVE To evaluate the effects of a native herbal tea in patients with type 2 diabetes. DESIGN Randomized, placebo-controlled, single-blind study. SETTING The Metabolic Centre at the University of Alberta Hospitals. SUBJECTS Forty volunteers with type 2 diabetes. INTERVENTIONS After a 1 month "run-in" period, subjects drank 250 mL/d of either the herbal tea or a placebo tea for 10 da...

The immune response to certain synthetic polypeptide antigens and native proteins has been shown to be controlled by immune response (Ir) genes, which reside in the murine major histoeompatibility complex (MHC) 1 (reviewed in 1). The expression of such Ir gene control has been localized to T cells, B cells, and/or antigen-presenting cells (2-4). Support for the concept of Ir gene expression in ...

context hepatitis b virus expanded program on immunization (epi) started on 1993 in iran. most surveys have assessed the level of response to vaccine by measuring the titers of anti-hbs. this meta- analysis aimed to summarize the iranian published data on the rate of vaccine-responders versus non-responders. moreover, the impact of variables such as age, gender, type of vaccine, etc. on the lev...

T cell suppression exerted by regulatory T cells represents a well-established phenomenon, but the mechanisms involved are still a matter of debate. Recent data suggest that anergic T cells can suppress responder T cell activation by inhibiting Ag presentation by dendritic cells (DC). In this study, we focused our attention on the mechanisms that regulate the susceptibility of DC to suppressive...

A soluble allogeneic effect factor (AEF) was produced by using H-2 congenic mouse strains and a serum.free cell culture medium. An AEF derived from untreated activated responder cells and irradiated stimulator cells provided helper cell function in a primary and secondary antibody response for both T-cell-depleted responder B cells and stimulator B cells. This interaction may be determined by g...

BACKGROUND Studies in macaques have indicated that androgens have some synergistic effects with FSH on folliculogenesis. This study investigated the usefulness of pretreatment with transdermal testosterone in low-responder IVF patients. METHODS Randomized clinical trial including 62 infertile women who had a background of the first IVF treatment cycle cancelled because of poor follicular resp...

Background To compare a flexible, multi-dose GnRH antagonist protocol with a long GnRH .agonist protocol in poor respo MaterialsAndMethods A randomized clinical trial of 70 poor responder patients (35 patients in GnRH antagonist protocol and 35 patients in long GnRH agonist protocol) was performed at Royan Institute, Tehran, Iran. Both groups were given a fixed dose of human menopausal gonadotr...

We study social preferences in a three-person ultimatum game experiment with one proposer and two responders. Any responder can unilaterally punish the proposer. In three treatments, we vary the pecuniary consequences of rejection in such a way that upon rejection of one responder the other responder is (i) affected negatively, (ii) not affected, and (iii) positively affected. We collect comple...

Methods We performed a retrospective, multicentric, chart review of PFAPA patients under colchicine prophylaxis. We distinguished one responder group, defined as patients, who had no more, or twice fewer crises under colchicine and another one of non-responders. Subgroup analyses were performed using the nonparametric Mann-Whitney test for the quantitative data and calculating the odds ratio an...
