Lipase-catalysed transesterification of rapeseed oil with ethanol to the corresponding ethyl ester was investigated to prove the activity of immobilized enzyme and thus, the concept. The activity was found to be similar to that of free enzyme.
CONCLUSION: Smart hydrogel composites were used for the transesterification of oil. Based on the results obtained, reversible loadable and mechanical stable hydrogel composites could
be developed for continuous working reactor concepts. (C) 2010 Society of Chemical Industry”
“Spinal tuberculosis (TB) accounts for GSK’872 price approximately half of all cases of musculoskeletal tuberculosis. Kyphosis is the rule in spinal tuberculosis and has potential detrimental effects on both the spinal cord and pulmonary function. Late-onset paraplegia is best avoided with the surgical correction of severe kyphosis, where at the same time anterior decompression of the cord is performed and the remnants of the tuberculosis-destroyed vertebral bodies are excised.
Review of the literature on late selleck products surgical treatment of TB-associated kyphosis; description and comparative analysis of the different surgical techniques.
Kyphosis can be corrected either at the acute stage or at the healed late stage of tuberculous infection. In the late stage, the stiffness of the spine and chronic lung disease are additional considerations for the surgical approach and technique. Contrary to the traditional
anterior transpleural approach used in the acute spinal tuberculosis infection, extrapleural approaches, either antero-lateral or direct posterior, are favored in late treatment.
The correction of deformity is only feasible with three-column osteotomies, and posterior vertebral column resection (PVCR) is the treatment of choice in extreme kyphosis. The prognosis of the neurologic deficit (late paraplegia) is dependent on the extent of gliosis of the spinal cord.”
“The
aim of this study was to evaluate the frequency and clinical associations of HLA-DR alleles in Brazilian Caucasian patients with polyarteritis nodosa (PAN) or microscopic polyangiitis (MPA). We evaluated 29 Caucasian patients with vasculitis classified RG-7112 concentration as PAN or MPA according to the American College of Rheumatology (ACR) 1990 Criteria, Chapel Hill Consensus Conference (CHCC) nomenclature for vasculitis and EULAR recommendations for conducting clinical studies in systemic vasculitis. HLA-DR alleles were typed using polymerase chain reaction-amplified DNA, hybridized with sequence-specific low resolution primers. DNA obtained from 59 Caucasian healthy blood donors were used as control. In order to evaluate if a specific HLA may have influence on the clinical profile of those diseases, we also divided the patients according to Birmingham vasculitis score (BVAS) and Five-Factors Score (FFS) at the time of diagnosis. Increased frequency of HLA-DRB1*16 (p = 0.023) and DRB4*01 (p = 0.048) was found in patients with higher disease activity at the time of diagnosis (BVAS >= 22).
