“Kinetics of thermal degradation occurring on polyester containing cationic dyeable comonomer units viz. 5-sulphoisophthalate moieties are studied by measurement of changes in intrinsic viscosity and carboxyl values on the polymer after subjecting the polymer chips to temperatures in the range 275-285 degrees C for different residence times ranging from 5 to 60 min and comparing with the homopolymer. The activation energy values for degradation are estimated from the kinetic data. Mechanical properties of the textured yarns produced from the partially oriented yarns (POY) spun under different residence times are measured. Yarn produced with higher residence time has
poor mechanical properties. The SEM images of the POY show presence Selleck C188-9 of particles at the surface of the yarn due to polymer degradation. The size of the particles as seen on the surface increase with increase of retention time. Addition LCL161 of thermal stabilizer helps in controlling the thermal degradation.

“Rheumatoid nodulosis is considered a benign variant of rheumatoid arthritis. Several therapies have been used with variable results. We report a 63-year-old man who presented with nodular lesions on the metacarpophalangeal joints and knees which were diagnosed of rheumatoid nodulosis. Topical tacrolimus was started with good response on
the following months.”
“Background: The use of anabolic androgenic steroids (AAS) has been associated with the use of illegal drugs. Earlier observations suggested that users of illegal drugs may use AAS for reasons other than increasing muscle strength or size. The aim of the present study was to investigate the motives for AAS use among outpatients at a substance abuse center in Stockholm, Sweden.
Methods: All male patients under the age of 50 were asked whether they had used AAS during a 2-month period. An MS survey was administered to those who reported AAS experiences in the admittance interview.
Results: Twenty of the 175 respondents (11%) reported using AAS. The most frequently reported Raf inhibitor motives were related
to anabolic effects (i.e., for a good-looking body, to become stronger, or to perform better in sports). However, some users reported other motives; for example, to conceal concomitant drug use, to alleviate insecurity or low self-esteem, to become brave, or in preparation of committing a crime. Furthermore, many respondents reported side effects that were associated with AAS; most notably, irritability and depression/suicidal ideation.
Conclusion: Some users of illicit drugs also use MS for reasons other than the anabolic properties of these compounds. Therefore, considering that MS may cause or contribute to diverse morbidity, it is important to ask users of illicit drugs about MS use, even when obvious external signs of MS use are lacking.
