BACKGROUND Among the seven different sigma factors in E. coli σ(70) has the highest concentration and affinity for the core RNA polymerase. The E. coli protein Rsd is regarded as an anti-sigma factor, inhibiting σ(70)-dependent transcription at the onset of stationary growth. Although binding of Rsd to σ(70) has been shown and numerous structural studies on Rsd have been performed the detailed ...

Fifty merino wethers (liveweight range from 44 to 81kg, average of 58.6kg) were lot fed for 42d and scanned through a dual X-ray absorptiometry (DXA) as both a live animal and whole carcass (carcass weight range from 15 to 32kg, average of 22.9kg) producing measures of total tissue, lean, fat and bone content. The carcasses were subsequently boned out into saleable cuts and the weights and yiel...

BACKGROUND Reflex sympathetic dystrophy (RSD) syndrome is a multifactorial disorder with clinical features of neurogenic inflammation that causes hypersensitivity to pain or severe allodynia as well as blood flow problems, swelling, skin discoloration and maladaptive neuroplasticity due to vasomotor disorders. Patients with major trauma are prone to homeostasis leading to inflammatory response ...

OBJECTIVE To explore the effects of renal sympathetic denervation (RSD) on pulmonary vascular remodeling in a model of pulmonary arterial hypertension (PAH). METHODS According to the random number table, 24 beagles were randomized into control, PAH and PAH+RSD groups (n=8 each). The levels of neurohormone, echocardiogram and dynamics parameters were measured. Then 0.1 ml/kg dimethylformamide ...

Repeated social defeat (RSD) is a murine stressor that models several key physiological, immunological, and behavioral alterations observed in humans exposed to psychosocial stress. RSD induces prolonged anxiety-like behavior associated with myeloid cell trafficking into the brain, including the hippocampus. Because the hippocampus (HPC) is a key area involved in neuroplasticity, behavior, and ...

The regulator of sigma D (Rsd) was identified as an RNA polymerase sigma70-associated protein in stationary-phase Escherichia coli with the inhibitory activity of sigma70-dependent transcription in vitro (M. Jishage and A. Ishihama, Proc. Natl. Acad. Sci. USA 95:4953-4958, 1998). Primer extension analysis of rsd mRNA indicated the presence of two promoters, sigmaS-dependent P1 and sigma70-depen...

We have previously demonstrated that catheter-based renal sympathetic denervation (RSD) could suppress atrial fibrillation (AF) in canines with short-time rapid right atrial pacing (RAP). However, the role of renal denervation on atrial remodeling is unclear. The aim of the present study was to explore the long-term effect of RSD on the atrial remodeling during prolonged RAP. Twenty mongrel dog...

An unusual case of a 2 1/2-year-old girl with reflex sympathetic dystrophy (RSD) of the left arm is described. She is the youngest RSD case ever presented in the literature. Upper extremity involvement is also rare in childhood RSD. She had both physical and psychological trauma in an earthquake preceding the disease. The association of RSD with a psychological disorder is stressed and awarenes...

The number of individual RSD applications received by UNHCR offices worldwide nearly doubled from 1997 to 2001, while UNHCR's RSD operations have been criticized for failing to implement basic standards of procedural fairness. Yet, although there is some literature critiquing how UNHCR determines refugee status, there is little literature examining whether UNHCR should do so, and if it should, ...
