Corynebacterium striatum (C striatum) has been considered a contaminant of blood culture in past decades. Here we report the case of a patient with acute deterioration of chronic renal failure. She received hemodialysis and died from C striatum bacteremia. By using a randomly amplified polymorphic DNA (RAPD) method, we found that an association existed between C striatum from the bloodstream an...

The striatum is critical for learning and decision making; however, the molecular mechanisms that govern striatum function are not fully understood. The extracellular signal regulated kinase (ERK) cascade is an important signaling pathway that underlies synaptic plasticity, cellular excitability, learning and arousal. This review focuses on the role of ERK signaling in striatum function. ERK is...

The striatum is connected to the cerebral cortex through multiple anatomical loops that process sensory, limbic, and heteromodal information. Tract-tracing studies in the monkey reveal that these corticostriatal connections form stereotyped patterns in the striatum. Here the organization of the striatum was explored in the human with resting-state functional connectivity MRI (fcMRI). Data from ...

introduiction: this study aimed to investigate the protective effects of 12-week voluntary exercise using a running wheel on the striatum  dopaminergic neurons against 6-hydroxydopamine lesions in rats. materials and method: twenty five rats were divided into three groups including healthy, parkinson and training-parkinson. the training groups were housed in individual cages geared with running...

The function of striatopallidal neurons is regulated by N-methyl-D-aspartate (NMDA) and dopamine D2 receptors. Previous studies show that immediate early gene induction by D2 receptor blockade is suppressed by NMDA receptor antagonists. Because the pharmacology of NMDA receptors depends on the incorporation of different NR2 subunits and NR2 subunits show regional and cellular differences in the...

Background: Central renin angiotensin system has an important role on the cerebral microcirculation and metabolism. Our previous work showed that inhibition of angiotensin converting enzyme (ACE) activity prior to induction of ischemia protected the brain from severe ischemia/reperfusion (I/R) injuries. This study evaluated the impacts of post-ischemic inhibition of ACE, enalapril, on brain inf...

Corynebacterium striatum is a potentially pathogenic microorganism that causes nosocomial outbreaks. However, little is known about its virulence factors that may contribute to healthcare-associated infections (HAIs). We investigated the biofilm production on abiotic surfaces of multidrug-resistant (MDR) and multidrug-susceptible (MDS) strains of C. striatum of pulsed-field gel electrophoresis ...

Statistical learning (SL) is the ability to extract regularities from environment. In domain of language, this fundamental in words and structural rules. lack reliable online measures, statistical word rule have been primarily investigated using offline (post-familiarization) tests, which gives limited insights into dynamics SL its neural basis. Here, we capitalize on a novel task that tracks s...

Embryonic striatal grafts develop a modular organization in which patches of tissue enriched in many transmitter substances characteristic of striatum (P regions) are embedded in surrounds (NP regions) expressing only low levels of these substances. Catecholaminergic fibers from the host brain, identified by their expression of tyrosine hydroxylase (TH), grow into such grafts and selectively te...

We determined mRNA expression of the ionotropic glutamate receptors NMDA (NR1, NR2A and NR2B subunits), AMPA (GluR2 subunit) and kainate (GluR6 subunit), as well as of the glutamate transporters GLAST and GLT1 in cerebral cortex and striatum of wild type (WT) and glutaryl-CoA dehydrogenase deficient (Gchh-/-) mice aged 7, 30 and 60 days. The protein expression levels of some of these membrane p...
