Herein, we described the physicochemical properties of deproteinized extract of calf blood(DECB) and established a hypoxia model treated with or without DECB to detect the sugar, lactic acid, protein, and ATP contents of mice and then identified and analyzed the differentially expressed genes between two groups using mRNA expression chip. According to the results of the airtight hypoxia experiment, mice in the model+DECB group had a signifi? cantly prolonged time of hypoxia tolerance compared with the model group. The biochemical test indicated that DECB could significantly increase the level of sugar, ATP and proteins and reduce the amount of lactic acid in mice. It also revealed that Hmgcs2, Cptla, Angptl4, Cyp8b], and Ehhadh genes were involved in mice energy metabolism, and were closely associated witli metabolic signaling pathway. These results suggest that DECB might be a potential drug to treat metabolic diseases. Among the genes with differential expression under hypoxia, Angptl4, Cyp8bl, and Ehhadh were critical factors for sugar metabolism. Hmgcs2 provided energy directly, and Cptla regulated cellular inflammatory responses, promoting energy metabolism.

＜正＞The worldwide demand for corneal transplantations cannot match by the supply of donor corneas, especially in most developing countries. There is a large need of developing new corneal substitute mimicking the native cornea in terms of optical,biomechanical and biological properties. The cornea has four main types of proteoglycan that play a critical role in collagen fibrogenesis and ***, obtaining purified proteoglycans has been a challenging task due to their high cost. In this study, we employed cyclodextrins as a proteoglycan substitute to engineer a biomimetic collagen-based matrix.

Electric fields modify the optical properties of nematic liquid crystals(NLCs) by changing the nematic molecular orientation or order parameters, which enables electro-optic applications of NLCs. However, the field-induced optic change is undesirable in some cases. Here, we experimentally demonstrate that polymer stabilization weakens the birefringence change of NLCs caused by the nanosecond electrically modified order parameter effect. The birefringence change is reduced by 65% in the NLC doped with 25% reactive monomer, which is polymerized close to the nematic-to-isotropic phase transition. This technique could be used in liquid crystal devices where the birefringence change is unfavored.

磁性介孔二氧化硅复合材料作为酶固定化载体具有优异的酶固定化性能和良好的磁分离性能,受到国内外学术界广泛关注。本文在自制的β-FeOOH空心微球表面上包覆致密的SiO_(2)保护层,在酸性条件下以P123为模板剂,十六烷基三甲基溴化铵(CTAB)为辅助导向剂成功制备出了磁性β-FeOOH@SiO_(2)@介孔SiO_(2)空心复合微球,最后在还原气氛下煅烧得到Fe_(3)O_(4)@SiO_(2)@介孔SiO_(2)空心微球。结果表明,所制备的Fe_(3)O_(4)@SiO_(2)@介孔SiO_(2)微球空心结构未坍塌,具有规整的球形结构,介孔SiO_(2)壳层(平均厚度约为11nm)均匀地包覆在β-FeOOH@SiO_(2)中空微球表面。伴随着CTAB量的增加,微球的最可几孔径由4.30nm减小到3.19nm,比表面积从376m2/g升高到640m2/g,孔容从0.36cm3/g升高到0.56cm3/g。复合微球的饱和磁化强度为11.3emu/g,矫顽力为111.5Oe,外加磁场作用下可以实现样品的快速分离,且样品的再分散性良好。当介孔孔径为4.30nm时,Fe_(3)O_(4)@SiO_(2)@介孔SiO2空心复合微球漆酶固定量高达234mg/g。固定化漆酶在不同pH、温度下的活性显著优于游离酶。

DS583争端方依据DSU第25条提起仲裁,并将其“视为”上诉仲裁。“仲裁”与“上诉”本是两个性质不同的争端解决方式,二者为替代关系,不能同时作为同一个争端的解决手段。WTO部分成员之间达成的MPIA,起到了衔接两个程序的作用。“DS583仲裁程序”实质为MPIA下的上诉仲裁程序的第一次实操,其裁决具有上诉仲裁裁决的效力,即该裁决为终局裁决,对双方具有法律约束力,且不会被撤销或被宣布无效。原因在于“DS583仲裁程序”与MPIA下的仲裁程序基本一致,且“DS583仲裁程序”处理的实体问题为“专家组结论”,而不是引起争端发生的最初争议措施。在上诉机构无法正常运行的情况下,DS583通过实质上为MPIA下的上诉仲裁程序解决了上诉问题,重新树立了成员对WTO争端解决机制的信心。
