OBJECTIVES Postsystolic shortening (PSS) has been proposed as a marker of myocardial dysfunction. Percutaneous transluminal septal myocardial ablation (PTSMA) is an alternative therapy for patients with hypertrophic obstructive cardiomyopathy (HOCM) that results in sustained improvements in atrial structure and function. We investigated the effects of PTSMA on PSS in HOCM patients using speckle...

Primary Sjögren's syndrome (PSS) is rare in India. Clinically manifest renal disease in PSS is uncommon and is usually an autoimmune tubulointerstitial nephritis presenting with distal renal tubular acidosis (dRTA) or a urinary concentrating defect. Hypokalemic paralysis due to dRTA in PSS is rare but well documented in medical literature. Rhabdomyolysis as a consequence of hypokalemia in PSS i...

The structure of poly(3,4-ethylenedioxythiophene)–poly(styrenesulfonate) (PEDOT Æ PSS) consists of an insulating PSS layer surrounding doped PEDOT grains. In this study, X-ray and ultraviolet photoelectron spectroscopy (XPS and UPS) are used to investigate the composition and electronic structure of as-loaded and lightly sputtered PEDOT Æ PSS films. The sputtered film shows a significant increa...

Cell patterning has emerged as an elegant tool in developing cellular arrays, bioreactors, biosensors, and lab-on-chip devices and for use in engineering neotissue for repair or regeneration. In this study, micropatterned surfaces were created using the layer-by-layer lift-off (LbL-LO) method for analyzing canine chondrocytes response to patterned substrates. Five materials were chosen based on...

Phosphatidylserine (PtdSer) in Chinese hamster ovary (CHO) cells is synthesized through the action of PtdSer synthase (PSS) I and II, which catalyzes the exchange of L-serine with the base moiety of phosphatidylcholine and phosphatidylethanolamine, respectively. The PtdSer synthesis in a CHO cell mutant, PSA-3, which lacks PSS I but has normal PSS II activity, was almost completely inhibited by...

BACKGROUND Peri-stent contrast staining (PSS) after metallic drug-eluting stent deployment is associated with target lesion revascularization and very late stent thrombosis. However, the type of PSS that influences the clinical outcomes is unknown. Therefore, we aimed to reveal which PSS type was influencing clinical outcomes. METHODS AND RESULTS This study included 5580 de novo lesions of 44...

Chronic fatigue is one of the most prevalent and debilitating symptoms in primary SS (pSS). Approximately 70% of pSS patients suffer from disabling fatigue, which is associated with reduced health-related quality of life. In this article, we review the instruments used for evaluating pSS-related fatigue, our current understanding of the underlying psychosocial and physiological mechanisms of fa...

Product Service Systems (PSS) that create value by sharing or extending the use of products are expected to improve environmental performances of offerings. However, Lifecycle Analysis (LCA) which provides a comprehensive view and assesses the environmental impacts of products is not well adapted to PSS. In this paper, an approach to help the environmental assessment of PSS using LCA during the...

Primary Sjögren’s syndrome (pSS) is a chronic autoimmune disorder of the exocrine glands with associated lymphocytic infiltrates in the affected glands. Dryness of the mouth and eyes results from involvement of the salivary and lacrimal glands. The efficacy of Rituximab (RTX) in pSS is still open to debate. This study delineates the signaling pathway involved in RTX-mediated down-regulation of ...
