防护服舒适性的评价方法

在今天竞争激烈的市场中 ,更需强调织物和服装的性能。大量的织物和表面处理方法被用于改善防护服的手感、吸湿性及许多其他性能。纺织品防护性和舒适性研究中心已开发了许多评价防护服舒适性和技术性能的有用方法。在许多情况下 ,防护性能的要求与舒适性要求会直接产生矛盾 ,因此在制定测试方法和标准时必须充分考虑防护服在实际使用时总的性能要求。1　性能标准工业集团 ,如ASTM、AATCC、ANSI、INDA、ISO等技术组织和政府管理部门已为防护服 (如防热服、医用隔离服、化学隔离服、净化室工作服等 )制定了性能标准。例如 1 971年国…

白水杜康的下一步

如果说2006年的白酒行业大事件是茅台价格超越了五粮液。那么2007年行业的最大热点莫过杜康。上半年，河南洛阳杜康宣布破产；下半年伊始，伊川杜康高调宣传欲收购汝阳杜康；紧接着，刘更生宣布伊川杜康计划整体上市；而在相邻的陕西白水杜康．经过了高端换血之后．大规模的媒体见面会在西安叫响了全国。当我们得知汝阳杜康的黯然沉戈、伊川杜康的下一步之后，白水杜康的下一步因为新人的加盟也变得暖昧起来。[第一段]     

Effect of proteolytic enzyme activity and heating on the mechanical properties of bovine single muscle fibres

The effect of proteolysis and heating on the mechanical properties of single muscle fibres isolated from bovine M. semitendinosus was investigated. Short incubations with μ-calpain (pH 7.5) and cathepsin B (pH 5.6) at room temperature reduced (P<0.01) the raw fibre strength by 50%. After subsequent heating, μ-calpain-incubated fibres were 20% weaker and cathepsin B-incubated fibres 50% weaker than heated controls. Fibres were incubated for 8 days at 2?°C under post-mortem like pH conditions (pH 5.6) or pH conditions optimal for the calpains (pH 7.5). At pH 5.6 no significant weakening of the fibres was observed when incubations were performed in 0.1, 1 or 10 mM Ca(2+). In contrast, incubation in 1 or 10 mM Ca(2+) at pH 7.5 decreased the strength of the fibres. Addition of the protease inhibitors E-64 or PD150,606 prevented this weakening, suggesting that the weakening is caused by proteolyses and not directly by Ca(2+).

Cleavage of desmin by cysteine proteases: Calpains and cathepsin B

The intermediate filament protein, desmin, was purified from pork longissimus dorsi and incubated with either μ-calpain, m-calpain or cathepsin B. Proteolysis of desmin was followed using SDS-PAGE and Western blotting. After incubation of desmin with the proteases, cleavage sites on the desmin molecule were identified by N-terminal sequencing of the different proteolytic fragments. Desmin incubated with either m-calpain or μ-calpain was primarily cleaved in the head and tail region leaving the rod domain relatively intact even after prolonged incubation. Incubation with cathepsin B produces a sequential C-terminal degradation pattern characteristic of this dipeptylpeptidase. The substrate primary structure was not found to be essential for regulation of the proteolytic activity of the cysteine peptidases studied. However, the degradation patterns obtained imply that calpains are involved in degradation of desmin early post-mortem, targeting the non-helical region of the desmin molecule and resulting in depolymerisation and initial disorganisation of the intermediate filament structures of the muscle cell.
