Dbs is a Rho-specific guanine nucleotide exchange factor (RhoGEF) with in vitro exchange activity specific for RhoA and Cdc42. Like many RhoGEF family members, the in vivo exchange activity of Dbs is restricted in a cell-specific manner. Here we report the characterization of a novel scaffold protein (designated cell cycle progression protein 1 [Ccpg1]) that interacts with Dbs and modulates its...

BACKGROUND Deep brain stimulation (DBS) is an established clinical therapy and computational models have played an important role in advancing the technology. Patient-specific DBS models are now common tools in both academic and industrial research, as well as clinical software systems. However, the exact methodology for creating patient-specific DBS models can vary substantially and important ...

The glucocorticoid (GC) receptor (GR), when liganded to GC, activates transcription through direct binding to simple (+)GRE DNA binding sequences (DBS). GC-induced direct repression via GR binding to complex "negative" GREs (nGREs) has been reported. However, GR-mediated transrepression was generally ascribed to indirect "tethered" interaction with other DNA-bound factors. We report that GC-ind...

conclusions ma is nowadays the most accurate stereotactic anatomic guide for targeting the human na. it is a representative example of how stereotactic microanatomy could serve the development of stereotactic microneurosurgery. following the currently used trajectory through the alic, a dbs electrode placement within the na, targeting the ma, is feasible, allowing either na or alic stimulation....

deep brain stimulation (dbs) is a neurosurgical procedure that enables brain structures to be stimulated electrically by a pacemaker implanted under the skin. in the 1980s, over a decade after its first use in pain, implantable dbs of the thalamus was performed to suppress tremor in parkinson’s disease (pd) refractory to drug treatments. primate-based research soon afterwards identified the sub...

Solvent properties play a central role in mediating the aggregation and self-assembly of molecular gelators and their growth into fibers. Numerous attempts have been made to correlate the solubility parameters of solvents and gelation abilities of molecular gelators, but a comprehensive comparison of the most important parameters has yet to appear. Here, the degree to which partition coefficien...

Hyperbranched multiarm copolymers (HMCs) have shown great potential to be excellent precursors in self-assembly to form various supramolecular structures in all scales and dimensions in solution. However, theoretical studies on the self-assembly of HMCs, especially the self-assembly dynamics and mechanisms, have been greatly lagging behind the experimental progress. Herein, we investigate the e...

Objective: There are not enough good instruments for assessing driving behavior in Iran. This study aimed to investigate factor structure, convergent and divergent validity, and reliability of driving behavior survey (DBS). Methods: The study method is descriptive and survey. Participants comprised 147 Sample selected by convenient method. Iranian drivers who completed DBS, Manc...
