background: it has been suggested that malfunction of immune system may cause testicular cancer. recently, our understanding of innate immune system has been expanded, by discovery of “toll- like receptors” (tlrs). some studies have shown that polymorphisms of tlr2 and 4 can effect on the risk of cancer. also, the role of tlrs 3and 9 have been shown in apoptosis of cancer cells and metastasis i...

background: type-i diabetes is an autoimmune inflammatory disease in which pancreatic ß-cells are selectively destroyed by infiltrating cells. tnf-related apoptosis-inducing ligand (trail) is a type-ii membrane protein of the tnf superfamily which is expressed in different tissues, including pancreas and lymphocytes. in humans, trail interacts with four membrane receptors. trail-r1 and trail-r2...

introduction: many people with amnesia would like to try herbal therapies. ginkgo biloba is one of the most popular herbs which is used to treat amnesia. the beneficial effects of this plant, however, has not been scientifically assessed yet. although, there have been some reports on the memory enhancement effect of ginkgo biloba, the mechanism of its action is not yet explained well. consideri...

objective(s): prostaglandins have been shown to mediate the gastro-protective effect of sodium hydrosulfide (nahs) but effect of nahs on mrna expression of prostaglandin e2 receptors (ep1, 3-4; eps) has not been investigated. therefore, this study designed to evaluate the effect of nahs on mrna expression of eps receptors in response to mucosal acidification and distention-induced gastric acid ...

kawasaki disease (kd) is an acute febrile systemic vasculitis of childhood characterized by elevated levels of inflammatory mediators at the acute stage. high-dose intravenous immunoglobulin (ivig) is well accepted as a conventional therapy for kd. the aim of the present study was to determine the expression level of toll like receptors (tlrs) and their corresponding signaling mediators in pbmc...

previous studies have shown that ascorbic acid (aa) plays a crucial role in mammalian brain as avitamin and neuronal modulator. there is increasing evidence indicating that dopaminergic system and aacould affect learning and memory processes. in addition, vitamin c acts as a dopamine antagonist in thebrain. the aim of the present study was to evaluate the intra-hippocampal co-administration of ...

background: it is not yet known which types of toll-like receptors (tlrs) are most effective in helicobacter pylori (h. pylori) recognition. it is also not known which gastric zones have the most prominent roles in tlr-mediated bacterial recognition. the aim of this work was to analyze the expression of tlr2 and tlr4 in biopsy specimens from h. pylori-infected patients. methods: thirty-eight pa...

conclusions regarding the findings of this study, it can be concluded that erα possibly cannot play an important role in the tumorigenesis and prognosis of the investigated malignant salivary gland tumors. results for acc, only one specimen expressed the er, and this was assessed as moderate. no specimens of mec expressed the er. the comparison of er expression between the two groups was not me...

Adenosine receptors (nomenclature as agreed by the NC-IUPHAR Subcommittee on Receptors [112]) are activated endogenous ligand adenosine (potentially inosine also at A3 receptors). Crystal structures for antagonist-bound [155, 316, 224, 62], agonist-bound [379, 205, 206] and G protein-bound A2A [49] have been described. The of an A1 receptor [130] adenosine-bound receptor-Gi complex [87] resolve...

Receptors. In their Communication (e202216011), Jan J. Weigand et al. report the selective separation of lithium, magnesium, and calcium using 4-phosphoryl pyrazolones as pH-regulated receptors.
