BACKGROUND Asthma is a major public health problem in the world, and recent findings suggest that stress influences asthma and asthma morbidity. The 10-item Perceived Stress Scale (PSS-10) is one of the most frequently used instruments to measure psychological stress. This study was conducted to evaluate the psychometric properties of the Persian versions of the PSS-10 in adults with asthma. ...

BACKGROUND AND PURPOSE Pure sensory stroke (PSS) usually is caused by a lacunar infarct; reports of PSS caused by cerebral hemorrhage have been rare. We correlated clinical and neuroradiologic findings in patients with PSS caused by cerebral hemorrhage. METHODS We retrospectively studied seven patients with appropriate clinical findings and lesions revealed by X-ray CT and MR imaging (five me...

OBJECTIVES Articular manifestations (AMs) occurred in approximately 30-60% of patients with primary SS (pSS). We conducted the current study to describe clinical presentation, specific treatment and to report clinical outcome of pSS patients with AM in a large bicentric French cohort. METHODS Clinical, biological and immunological features of 419 consecutive patients with pSS were recorded in...

The aim of study is designed of Power System Stabilizer (PSS) based on H4 approach for power system stabilization. The uncertainties in power system modeling and operations are considered at designing of H4 PSS. The bounds of power system parameters are determined over a wide range of low frequency operating conditions. These bounds are used to design a robust H4 PSS. A sample power system comp...

BACKGROUND Progressive systemic sclerosis (PSS) is a multisystem disorder of unknown etiology. Interstitial lung disease (ILD) is a major cause of mortality in this condition, and a major challenge in this regard is to identify parameters that would predict the onset or progression of ILD in patients with PSS. Abnormal cellularity of BAL fluid (BALF) has been demonstrated in patients with PSS w...

OBJECTIVES The relationship between cognitive symptoms and underlying neuropathology in primary SS (PSS) is poorly understood. We used high-resolution quantitative brain MRI to identify potential structural correlates of cognitive symptoms. METHODS Subjects completed a comprehensive neuropsychometric evaluation. Imaging was performed on a 3 T MRI scanner with T(1) and proton density-weighted,...

BACKGROUND This paper describes the development of a Japanese version of the Perceived Stress Scale (PSS), and examines the equivalence between the original and translated version. The PSS is one of the few instruments to measure a global level of perceived stress, and has been widely used in a range of clinical and research settings. The PSS has already been translated into several languages, ...

Background/Aims: Primary Sjögren’s syndrome (pSS) is a systemic autoimmune disease characterized by decreased salivary and lacrimal gland secretions. B-cell abnormalities have been identified in pSS. We tested the leptin (LP) and leptin receptor (LR) levels in pSS and to analyze relationship between their levels and clinical manifestation of pSS. Methods: We assayed LP and LPR levels measured b...

This work describes the fabrication of poly(4-styrenesulfonic acid)-doped polyaniline/graphene (PSS-doped PANI/graphene) nanocomposites and their use as sensing elements for hydrogen sulfide (H2S) detection. PSS with a weight-average molecular weight (Mw) of 1.96 × 10(6) was synthesized using low-temperature free-radical polymerization. The PSS was used as both a doping agent and a binding agen...

Insight into the strengths, weaknesses, opportunities, and threats (SWOT) of planning support systems (PSS) is fragmented between users and system developers. The lack of combined insights blocks development in the right direction and makes potential users hesitant to apply PSS in planning. This study presents SWOT of PSS from a combined user ^ developer perspective. We first express them in te...
