5-Aminosalicylic acid (5-ASA) is currently prepared by electrochemical reduction of 5-nitrosalicylic acid (5-NSA) in acidic media. In this work, electrolytic reduction of 5-NSA in alkaline media is presented. Reactionconditions and parameters such as anode and cathode electrodes, electrolyte type, reaction time, temperature,current, and the pH for isolation of product are investigated. The yiel...

The factor structure of the Negative Symptom Assessment (NSA), a standardized negative symptoms rating scale, was systematically evaluated in a group of 223 inpatients with schizophrenia. Confirmatory factor analyses found that a six-factor model best described the NSA. More specifically, the domains of Communication, Emotion/Affect, Social Involvement, Motivation, Gross Cognition, and Retardat...

Introduction: Neck shaft angle of femur (NSA) and body mass index (BMI) are important determinants of fracture neck femur which is considered to be a health burden of our society. Methods: In this study fifty people aged more than fifty years were selected consecutively after interview and examination in department of Radio diagnosis, Medical College, Kolkata. Neck shaft angle was measured on t...

Over a 26 month period 17% of couples having treatment in our clinical programmes selected a commercially available protein (normal serum albumin, NSA) prepared from pooled human sera instead of using their own serum as a supplement for their embryo culture media. In a retrospective analysis of >2000 gonadotrophin-stimulated cycles and 1000 cycles where frozen/thawed embryos were transferred, f...

BACKGROUND As Staphylococcus aureus (SA) remains one of the leading cause of infective endocarditis (IE), this study evaluates whether S. aureus is associated with more severe infections or worsened outcomes compared to non-S. aureus (NSA) organisms. METHODS All patients undergoing valve surgery for bacterial IE between 1995 and 2013 at our institution were included in this study (n = 323). C...

Abstract The Nubian sandstone aquifer (NSA) is defined by using 19 vertical electrical sounding (VES) stations, 201 gravity which define the structures that control configuration of NSA, and 183 land magnetic lower surface NSA determining depth basement surface. In order to assess top we collected analyzed deep VESes. upper spans from 707 1154 m, according interpretation results for various geo...

Nop-shadows Analysis (NSA) is an efficient static typestate analysis, which can be used to eliminate unnecessary monitoring instrumentations for runtime monitors. In this paper, we propose two optimizations to improve the precision of NSA. Both of the optimizations filter interferential configurations when determining whether a monitoring instrumentation is necessary. We have implemented our op...
