An increase in tubular fluid flow rate (TFF) stimulates Na reabsorption and K secretion in the cortical collecting duct (CCD) and subjects cells therein to biomechanical forces including fluid shear stress (FSS) and circumferential stretch (CS). Intracellular MAPK and extracellular autocrine/paracrine PGE2 signaling regulate cation transport in the CCD and, at least in other systems, are affect...

BACKGROUND Psychological distress (e.g., depression and anxiety) has been regarded as the main cause of leaving work for people living with HIV/AIDS (PLWHA) in workplaces. This study aims to explore the associations of functional social support (FSS) and psychological capital (PC) with depressive and anxiety symptoms among PLWHA employed full-time. METHODS This cross-sectional study was perfo...

BACKGROUND Fatigue affects up to 68% of subjects following stroke. In non-stroke patients, associations are reported between chronic fatigue and both hypertension and hypotension. We hypothesized that, in patients with stroke or transient ischaemic attack (TIA), an association may exist between fatigue and abnormal blood pressure (BP) detected on ambulatory monitoring. METHODS Subjects recrui...

Mechanical loading of bone is important for the structural integrity of the skeleton and the maintenance of bone mass. Mechanically loading bone generates fluid shear stress (FSS) across the surface of bone cells resulting in the induction of cyclooxygenase-2 (COX-2) and release of prostaglandins, both of which are necessary for mechanically induced bone formation. However, the mechanisms by wh...

Introduction Fragment spaces (FSs) are an elegant way to model a large or even infinite number of chemical compounds and their synthetic accessibility. A FS consists of molecular fragments and a set of rules defining how fragments can be combined to products. In virtual screening experiments, FSs might include products with undesired functional groups or inadequate central building blocks. The ...

The HIV-1 frameshift-stimulating (FSS) RNA, a regulatory RNA of critical importance in the virus' life cycle, has been posited as a novel target for anti-HIV drug development. We report the synthesis and evaluation of triazole-containing compounds able to bind the FSS with high affinity and selectivity. Readily accessible synthetically, these compounds are less toxic than previously reported ol...

has been optioned in patients with early-stage epithelial ovarian cancer (EOC), if they meet several clinicopathologic criteria. Although a variety of studies have reported the outcomes of patients who have undergone FSS and discussed the appropriateness of candidates for this surgical procedure [1-4], one of the major concerns of FSS is a possible increase in recurrence. Indeed, confining to s...

AIM To investigate the relationship between effective fentanyl sublingual spray (FSS) doses for breakthrough cancer pain (BTCP) and around-the-clock (ATC) transdermal fentanyl patch (TFP). METHODS Adults tolerating ATC opioids received open-label FSS for 26 days, followed by a 26-day double-blind phase for patients achieving an effective dose (100-1600 µg). RESULTS Out of 50 patients on ATC...

Cocaine-experienced Wistar and Wistar Kyoto (WKY) rats received four daily repeated forced swim stress sessions (R-FSS), each of which preceded 4-hour cocaine self-administration sessions. Twenty-four hours after the last swim stress, cocaine valuation was assessed during a single-session threshold procedure. Prior exposure to R-FSS significantly altered cocaine responding in Wistar, but not WK...

A new architecture for a low-profile miniaturized-element frequency selective surface based on complementary structure capable of providing a high angular stable performance is proposed. The proposed FSS is composed of an array of convoluted cross dipoles and its complementary slots pattern that is separated by a thin dielectric substrate. An equivalent circuit model for this FSS is presented t...
