Receptors for the neuropeptide somatostatin (SS) were evaluated in vitro and in vivo in various human lymphatic tissues, ie, thymus, spleen, and lymph nodes; thymic carcinoids and thymomas were also tested. The receptors were measured in vitro using receptor autoradiography on tissue sections incubated with the SS analog 125I-[Tyr3]-octreotide or 125I-[Leu8,D-Trp22,Tyr25]-SS-28. All tissues wer...

Hemodynamic forces in the form of shear stress (SS) and mechanical strain imposed by circulating blood are recognized factors involved in the control of systemic endothelial cell (EC) cytoskeletal structure and function. However, the effects of acute SS on pulmonary endothelium have not been precisely characterized, nor the mechanism of rapid SS-induced EC cytoskeletal rearrangement understood....

KCl cotransport (KCC) activity contributes to pathologic dehydration in sickle (SS) red blood cells (RBCs). KCC activation by urea was measured in SS and normal (AA) RBCs as Cl-dependent Rb influx. KCC-mediated volume reduction was assessed by measuring reticulocyte cellular hemoglobin concentration (CHC) cytometrically. Urea activated KCC fluxes in fresh RBCs to levels seen in swollen cells, a...

In this study, a 'green chemistry' approach was introduced to synthesize silk sericin (SS)-capped silver nanoparticles (AgNPs) under an alkaline condition (pH 11) using SS as a reducing and stabilizing agent instead of toxic chemicals. The SS-capped AgNPs were successfully synthesized at various concentrations of SS and AgNO3, but the yields were different. A higher yield of SS-capped AgNPs was...

the purposes of this research have been to determine the wastewater quality of a typical railroad repair workshop and to find a way to reduce the concentrations of present contaminants especially oil and grease. the mean concentrations of oil, cod and ss in the wastewater studied were 287.69, 775.85 and 28723, respectively with average daily discharge to be 30-35 m3. three successive treatment ...

Physiologic laminar shear stress (SS) is crucial for normal vascular structure and function. As a result of anemia-related lower whole-blood viscosity (WBV), SS could be reduced in patients with ESRD and might be associated with arterial functional alterations. In 44 patients with ESRD and 25 control subjects, brachial artery (BA) compliance and BA diameter changes (flow-mediated dilation [FMD[...

Thermal injury and tissue sticking are two major concerns in the electrosurgery. In the present study, the effect of lateral thermal injury caused by different electrosurgical electrodes on wound healing was investigated. An electrosurgical unit equipped with untreated (SS) and titanium oxide layer-coated (TiO2-coated) stainless steel needle-type electrodes was used to create lesions on the rat...

Somatostatin-14 (SS) significantly increased inositol-1,4,5-trisphosphate (IP3) accumulation in rat hypothalamic, striatal, frontoparietal cortical and hippocampal slices. However, this stimulation of IP3 accumulation by SS was highest in the frontoparietal cortex and hippocampus. The effect was already significant with 0.01 microM in the frontoparietal cortex (P < 0.05) and hippocampus (P < 0....

BACKGROUND Sjögren's syndrome (SS) has been associated with bronchial hyperresponsiveness and asthma; however, no population-based cohort study has been performed. We evaluated the risk of asthma in patients with primary SS in a nationwide population. METHODS We conducted a retrospective cohort study using data from the National Health Insurance Research Database in Taiwan. The primary SS gro...
