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 ...

We recently described an area in the ferret posterior suprasylvian (PSS) cortex characterized by a high proportion of direction selective neurons. To answer the question whether area PSS subserves functions similar to cat posteromediolateral suprasylvian area (PMLS) and monkey medial temporal area (MT) we investigated the contribution of area PSS to visual motion perception and optokinetic nyst...

OBJECTIVE To translate the Perceived Stress Scale (versions PSS-4, -10 and -14) and to assess its psychometric properties in a sample of general Greek population. METHODS 941 individuals completed anonymously questionnaires comprising of PSS, the Depression Anxiety and Stress scale (DASS-21 version), and a list of stress-related symptoms. Psychometric properties of PSS were investigated by co...

BACKGROUND Primary Sjögren's syndrome (pSS) is one of the most common chronic systemic autoimmune diseases, and thrombocytopenia is one of the hematological manifestations of pSS. When platelet and endothelial cells are activated, P-selectin is expressed on the cell surface. This study aimed to investigate the role of P-selectin autoantibodies in the pathogenesis of thrombocytopenia in pSS. MAT...

The Helicobacter pylori pss gene, coding for phosphatidylserine synthase (PSS), was cloned and sequenced in this study. A polypeptide of 237 amino acids was deduced from the PSS sequence. H. pylori PSS exhibits significant amino acid sequence identity with the PSS proteins found in the archaebacterium Methanococcus jannaschii, the gram-positive bacterium Bacillus subtilis, and the yeast Sacchar...

Hyaluronidase (HAase), a class of enzymes which degrade hyaluronic acid (HA), are involved in the spread of infections/toxins, ovum fertilization, and cancer progression. Thus, HAase inhibitors may have use in disease treatments. We evaluated 21 HAase inhibitors against HYAL-1, testicular, honeybee, and Streptomyces HAases. Among these inhibitors, polymers of poly (styrene-4-sulfonate) (PSS) (i...

This paper deals with the design of both single input and dual input conventional PSS which is used to damp the low frequency rotor oscillations taking place in power systems. The single input PSS used here are power based derivative type and speed based lead-lag type stabilizer, the dual input stabilizer, PSS3B has two inputs namely from change in speed and deviation of electrical power and ha...
