回火处理对生物基熔纺氨纶纤维力学性能影响

为了研究回火温度对生物基熔纺氨纶纤维力学性能的影响。设定了50,100,120℃3个温度对纤维进行回火处理。采用傅里叶变换红外光谱法、凝胶渗透色谱法、差示扫描量热法分别研究了回火温度对生物基熔纺氨纶纤维的官能团、分子量分布、结晶面积等的影响，单丝强力测试了回火温度对生物基熔纺氨纶纤维断裂强度、断裂伸长率、300%定伸长应力、300%弹性回复率的影响。研究结果表明，回火温度导致的官能团变化对生物基熔纺氨纶的力学性能影响较小。回火温度为100℃时，该纤维的大分子生成和小分子析出相对降低，大分子含量为8.4%，硬段区的结晶峰为一个，结晶面积为1.75 J/g。随着回火温度增加，大分子增加，结晶面积减少，试样的断裂强度增加、断裂伸长率也增加，300%定伸长应力和300%弹性回复率呈下降趋势。综合考虑回火温度、大分子含量、硬段结晶等因素，回火温度为100℃时，生物基熔纺氨纶的力学性能最佳。     

Resveratrol Treatment Prevents Increase of Mast Cells in Both Murine OVA Enteritis and IL-10−/− Colitis

Mast cells are involved in allergic and other inflammatory diseases. The polyphenol resveratrol is known for its anti-inflammatory properties and may be used as nutraceutical in mast cell associated diseases. We analyzed the effect of resveratrol on mast cells in vivo in ovalbumin-induced allergic enteritis as well as experimental colitis in IL-10^−/− mice which received resveratrol via drinking water. Treatment with resveratrol prevented the increase in mast cells in both allergic enteritis and chronic colitis in duodenum as well as in colon. Further, it delayed the onset of diseases symptoms and ameliorated diseases associated parameters such as tissue damage as well as inflammatory cell infiltration in affected colon sections. In addition to the findings in vivo, resveratrol inhibited IgE-dependent degranulation and expression of pro-inflammatory cytokines such as TNF-α in IgE/DNP-activated as well as in LPS-activated bone marrow-derived mast cells. These results indicate that resveratrol may be considered as an anti-allergic and anti-inflammatory plant-derived component for the prevention or treatment of mast cell-associated disorders of the gastrointestinal tract.

How green is green? Sampling and perception in assessing green seeds and chlorophyll in canola

Green seeds are used as a grading factor in estimating chlorophyll in canola and rapeseed in the Canadian and U.S.A. grading systems. This work examines the effect that sampling and perception have on the estimation of green seeds as well as the effect that sampling has on the determination of chlorophyll. Individual seed analysis indicated that in order to be considered as green, seeds needed to contain between 200 and 400 mg/kg chlorophyll. Variation due to binomial sampling played a predominant role in the error in determining the green seed levels in canola. Sampling of large numbers of seeds, as in the loading of export shipments, reduced the error. Binomial sampling also contributed to the error in chlorophyll determination even with sample sizes as large as 500. Differences in perception of green also were noted between individuals with coefficients of variation as high as 50% at the 1% green seed level. The combination of perception error and sampling error may result in samples of 1,000 seeds drawn from a mass with 2% green seeds having green seed counts ranging from 0.96 to 3.04%, 19 times out of 20.     

Mitochondria Turnover and Lysosomal Function in Hematopoietic Stem Cell Metabolism

Hematopoietic stem cells (HSCs) reside in a hypoxic microenvironment that enables glycolysis-fueled metabolism and reduces oxidative stress. Nonetheless, metabolic regulation in organelles such as the mitochondria and lysosomes as well as autophagic processes have been implicated as essential for the determination of HSC cell fate. This review encompasses the current understanding of anaerobic metabolism in HSCs as well as the emerging roles of mitochondrial metabolism and lysosomal regulation for hematopoietic homeostasis.

Pathophysiological Roles of Actin-Binding Scaffold Protein,Ezrin

Ezrin is one of the members of the ezrin/radixin/moesin (ERM) family of proteins. It was originally discovered as an actin-binding protein in the microvilli structure about forty years ago. Since then, it has been revealed as a key protein with functions in a variety of fields including cell migration, survival, and signal transduction, as well as functioning as a structural component. Ezrin acts as a cross-linker of membrane proteins or phospholipids in the plasma membrane and the actin cytoskeleton. It also functions as a platform for signaling molecules at the cell surface. Moreover, ezrin is regarded as an important target protein in cancer diagnosis and therapy because it is a key protein involved in cancer progression and metastasis, and its high expression is linked to poor survival in many cancers. Small molecule inhibitors of ezrin have been developed and investigated as candidate molecules that suppress cancer metastasis. Here, we wish to comprehensively review the roles of ezrin from the pathophysiological points of view.     

Carrageenan: A Food‐Grade and Biocompatible Support for Immobilisation Techniques

Immobilisation of both enzymes and whole‐cell systems is of major importance in the improvement of the stability, activity and reusability of these biocatalysts. This review describes the use of the naturally occurring polysaccharide carrageenan as a support for the immobilisation of biocatalysts. Carrageenan is a food‐grade and biocompatible support material extracted from red seaweeds. Before focusing on the use of carrageenan as an immobilisation support, an overview is given of the present uses of biocatalysts in industrial processes. The basic concepts of enzyme and whole‐cell immobilisation are discussed, as well as the background of carrageenan as a biopolymer. Several examples of enzymes and whole‐cell systems immobilised in carrageenan are discussed. A list of the most relevant patents in this field is presented as well as a list of enzymes and cell systems immobilised in carrageenan as described in the literature.
