Conclusions: As evidenced by shortening of the external urethral sphincter electromyogram silent period Selleckchem JSH-23 in ovariectomized rats, the disruption of coordination between the external urethral sphincter and the detrusor muscle could decrease urine outflow and in turn voiding efficiency. Estrogen replacement reverses these changes, suggesting that the central pathways responsible for detrusor-sphincter coordination are modulated by gonadal hormones.”
“The

brain mechanisms involved in processing another’s physical pain have been extensively studied in recent years. The link between understanding others’ physical pain and emotional suffering is less well understood. Using whole brain analysis and two separate functional localizers, we characterized FGFR inhibitor the neural response profiles of narrative scenarios involving physical pain (PP), and scenarios involving emotional pain (EP) with functional magnetic resonance imaging (fMRI). Whole brain analyses revealed that PP narratives activated the Shared Pain network, and that the brain regions responsible for processing EP overlapped substantially with brain regions involved in Theory of Mind. Region of interest (ROI) analysis provided a finer-grained view. Some regions responded to stories involving physical states, regardless of painful content (secondary sensory regions),

some selectively responded to both emotionally and physically painful events (bilateral anterior thalamus and anterior middle cingulate cortex), one brain region responded selectively to physical pain (left insula), and one brain region responded selectively to emotional pain (dorsomedial prefrontal

GNA12 cortex). These results replicated in two groups of participants given different explicit tasks. Together, these results clarify the distinct roles of multiple brain regions in responding to others who are in physical or emotional pain. (C) 2011 Elsevier Ltd. All rights reserved.”
“We have developed a mammalian expression system suitable for the production of enzymatically biotinylated integral membrane proteins. The key feature of this system is the doxycycline (dox)-regulated co-expression of a secreted variant of Escherichia coli biotin ligase (BirA) and a target protein with a 13-residue biotin acceptor peptide (BioTag) appended to its extracellular domain. Here we describe the expression and functional analysis of three G-protein coupled receptors (GPCRs): protease-activated receptors (PARs) 1 and 2, and the platelet ADP receptor, P2Y(12). Clonal Chinese hamster ovary (CHO) Tet-On cell lines that express biotinylated GPCRs were rapidly isolated by fluorescence-activated cell sorting following streptavidin-FITC staining, thereby circumventing the need for manual colony picking. Analysis by Western blotting with streptavidin-HRP following endoglycosidase treatment revealed that all three GPCRs undergo N-linked glycosylation.
