OBJECTIVES To determine the prevalence of autonomic dysfunction (dysautonomia) among patients with primary Sjögren's syndrome (PSS) and the relationships between dysautonomia and other clinical features of PSS. METHODS Multicentre, prospective, cross-sectional study of a UK cohort of 317 patients with clinically well-characterised PSS. Symptoms of autonomic dysfunction were assessed using a v...
BACKGROUND Primary Sjögren's syndrome (pSS) is a common chronic autoimmune disease characterized by lymphocytic infiltration of exocrine glands and peripheral lymphocyte perturbation. In the current study, we aimed to investigate the possible pathogenic implication of autophagy in T lymphocytes in patients with pSS. METHODS Thirty consecutive pSS patients were recruited together with 20 patie...
Subcellular localization of photosensitizers (PSs) determines the therapeutic efficacy in the photodynamic therapy. However, among the subcellular compartments, there has been little effort to deliver the PSs selectively into the plasma membrane and examine the phototherapeutic efficacy of membrane-localized PSs. Here, we developed a liposomal delivery system to localize the hydrophobic PSs sel...
This paper proposes a genetic algorithm based method to tune the parameters of a proportional plus integral plus derivative (PID) power system stabilizer (PSS). A classical parameter optimization approach is integrated within the genetic search process. To assess the quality of system dynamic performance a quadratic performance index is adopted within the tuning process. To enhance the overall ...
This study reports on the use of a template that is made of silver nanoparticles (ANPs) that are dispersed on a patterned sapphire substrate (PSS) to improve the light output power of GaN-based light-emitting diodes (LEDs). The dipping of a sapphire substrate in hot H2SO4 solution generates white reaction products that are identified as a mixture of polycrystalline aluminum sulfates. These whit...
Sex differences and pretrauma functioning have been understudied in examinations of posttraumatic stress symptoms (PSS) and health. This study examined relationships between sexual harassment and assault in the military (MST), PSS, and perceived physical health when accounting for pre-MST PSS, pre-MST health, and current depression. Relationships were examined separately in 226 female and 91 ma...
This paper focuses on the use of advanced techniques in genetic algorithm for solving power system stabilization control problems. Dynamic stability analysis of power system is investigated considering Proportional-IntegralDerivative power system stabilizer for modern power systems. Gain settings of PID-PSS are optimized by minimizing an objective function using genetic algorithm (GA). Dynamic ...
A method to quantify the individual contribution of power system stabilisers (PSSs) to enhance system performance is proposed. Enhancement in system performance from PSS is measured through increased system transfer capability and the margin of stability thus achieved, and considering an N 1 contingency criterion. The method is based on cooperative game theory and makes use of the Shapley value...
There is a growing body of academic literature that deals with the gap between Planning Support Systems (PSS) and daily urban planning practices. In response to the identified bottlenecks for implementation and insights from knowledge management, a new approach for improving PSS implementation was recently proposed. This Mediated Planning Support (MPS) approach is grounded in several theoretica...
Previous studies have focused on the effects of propylene glycol alginate sodium sulfate (PSS) against thrombosis, but the anti-inflammatory potential is unknown. Therefore, we specifically focused on the protective effects of PSS on cerulein-induced acute pancreatitis (AP) using a mouse model, and investigated the mechanism of PSS on autophagy and apoptosis via the Mitogen-activa...
