Group I metabotropic glutamate receptors (mGluRs) increase cellular levels of inositol-1,4,5-triphosphate (IP3) and thereby trigger intracellular Ca2+ release. Also, group I mGluRs are organized with members of Homer scaffold proteins into multiprotein complexes involved in postreceptor signaling. In this study, we investigated the relative importance of the IP3/Ca2+ signaling and novel Homer p...

PMCA2, a major calcium pump, is expressed at particularly high levels in Purkinje neurons. Accordingly, PMCA2-null mice exhibit ataxia suggesting cerebellar pathology. It is not yet known how changes in PMCA2 expression or activity affect molecular pathways in Purkinje neurons. We now report that the levels of metabotropic glutamate receptor 1 (mGluR1), which plays essential roles in motor coor...

background apo-lipoprotein e (apoe) and carnitine palmitoyltransferase1-a (cpt1-a) genes are well known to be involved in the pathophysiology of psychiatric disorders such as schizophrenia but regarding their cpg island methylation status data is sparse. objectives the aims of the current study were to highlight the effect of the promoter “hypermethylation” in the development of scz. patients a...

conclusions this study showed that ifnβ-1a decreased oxidant impacts in ms patients, but had no influence in improving mitochondrial dysfunction. results in the patients group (30 patients), a significant difference was observed in their measured biochemical factors in comparison to the control group (p = 0.001), however, after six months of using ifnβ-1a, only mda was shown in the main (p = 0....

The HOMER Micropower Optimization Model is a computer model developed by the U.S. National Renewable Energy Laboratory (NREL) to assist in the design of micropower systems and to facilitate the comparison of power generation technologies across a wide range of applications. HOMER models a power system’s physical behavior and its life-cycle cost, which is the total cost of installing and operati...

This article examines social interaction in Homer in the light of modern conversation analysis, especially Grice's theory of conversational implicature. Some notoriously problematic utterances are explained in terms of their 'off-record' significance. One particular off-record conversation strategy is characterized by Homer as kertomia, and this is discussed in detail. The article focusses on s...
