不同温度下两种索科线虫寄生前期幼虫生活力及感染力的研究

对长沙多索线虫（AgamermischangshaensisBaoetal,1992）和寄生在飞虱体内的两索属待定种的寄生前期幼虫在不同温度下的存活力和感染力进行了观测,结果表明：长沙多索线虫的寄生前期幼虫在OC时存活力最大,存活最长时间可达22d;99％的幼虫可存活12d,且感染力可达80％．两索线虫（Amphimermissp）尽管与前者有相同的宿主,但在存活力方面有很大差异,褐飞虱体内寄生的两索线虫寄生前期幼虫在0℃时存活可达7d,存活时间最长者可达13d,存活7d的幼虫感染率在66％左右．由此,可以说明低温条件下能延长幼虫寿命,保持其感染力．     

基于生存理论的两类博弈模型

研究基于生存理论的两类博弈模型(非合作博弈与合作博弈模型)及平衡的存在性。将生存理论思想植入到非合作博弈与合作博弈模型中,构建两类新的博弈模型,并给出新模型的非合作博弈强(弱)平衡和合作博弈强(弱)平衡定义。在满足一定的条件下,得到强(弱)平衡的4个存在性定理。这一工作在理论上拓宽了博弈论的研究范畴,具有一定的现实意义。     

白桦花粉生活力研究

采用TTC染色法、I-KI染色法和离体培养基萌发法测定白桦花粉活力;同时研究温度、蔗糖浓度、培养时间和储藏时间对白桦花粉离体培养活力的影响。结果表明:TTC和I-KI染色法不适合检测白桦花粉活力;白桦适宜花粉萌发的条件为20℃温度水平、15%蔗糖浓度、培养6 h,花粉萌发率为24.1%;4℃低温干燥环境可保存330 d。     

Against the empirical viability of the Deutsch–Wallace–Everett approach to quantum mechanics

The subjective Everettian approach to quantum mechanics presented by Deutsch and Wallace fails to constitute an empirically viable theory of quantum phenomena. The decision theoretic implementation of the Born rule realized in this approach provides no basis for rejecting Everettian quantum mechanics in the face of empirical data that contradicts the Born rule. The approach of Greaves and Myrvold, which provides a subjective implementation of the Born rule as well but derives it from empirical data rather than decision theoretic arguments, avoids the problem faced by Deutsch and Wallace and is empirically viable. However, there is good reason to cast doubts on its scientific value.     

Synergistic effect of trace elements and flavonoids from Epimedium koreanum Nakai on primary osteoblasts

Several trace elements, particularly, manganese （Mn） and zinc （Zn）, are essential in bone metabolism as cofactors for specific enzymes. It has been reported that there exists the relationship between osteoporosis and trace element-deficiency and the efficacy of Ca, Mn and Zn supplementation on spinal bone mineral density in postmenopausal women. Traditional Chinese medicines （TCM）, such as Herba epimedii, were proved to be effective for prevention of osteoprosis in vivo; however, the efficacy of the main constituents and/or crude extract was not ideal in vitro, which suggested that they may work in another way. The purpose of the present study was to examine whether the combination of icariin and total flavonoids （TF） from Herba epimedii with mineral elements, which were abundant in Herba epimedii, would have a more beneficial effect on the viability and differentiation of primary osteoblasts than either agent alone, and to analyze the dada for a possible synergistic, additive or antagonistic effect. The combinations of 10 μmol/L Zn, Ca and Mn with icariin and total flavonoids greatly improved the cell viability and meanwhile dramatically enhanced the alkaline phosphatase activity as compared to each agent alone. On the other hand, an increased cell growth inhibition was also observed by combining 0.1 μmol/L, 1 pmol/L Zn with 10μmol/L icariin, and 10 μmol/L Mn with 0.06 μg/mL total flavonoids. Meanwhile a decreased alkaline phosphatase activity was also found in several icariin-Zn/Mn and total flavonoids-Zn/Ca/Mn combinations. These results suggested that mineral elements （Zn, Ca, Mn） greatly enhanced the efficacy of icariin and total flavonoids from Herba epimedii on the viability and differentiation of primary osteoblasts by certain combinations.

Resuscitation of cadaveric livers from non-heart-beating donors after warm ischemic insult: a novel technique tested in the rat

Clinical liver transplantation has become the therapy of choice in end-stage liver disease, but the limited availability of suitable donor organs still impedes its widespread application. In order to increase the availability of donor organs for liver transplantation, it would be advantageous if ischemically damaged livers could be resuscitated from cadavers in which the heart has stopped beating. A method for doing this has been developed in a rat model. Compared to livers excised from rats in which the heart is still beating, severe deteriorations of tissue integrity and functional performance were evident in predamaged livers after cold preservation without supplementary treatment. A treatment of those livers which included an antioxidant rinse with superoxide dismutase, and venous vascular insufflation of gaseous oxygen during preservation, completely prevented tissue alterations upon reperfusion, and promoted a functional recovery of the livers, making them comparable to organs harvested from heart-beating donors.     

角膜活性评估方法综述

角膜内皮控制着角膜的水合作用与厚度,从而决定着角膜的透明度,所以无论哪一种角膜保存方法,都必须保证角膜内皮有较高的活性或细胞存活率.几十年来,随着角膜保存方法的发展,角膜内皮活性评估方法得到了较大的重视,并出现了许多方法,如简单实用的联合染色法等.本文对这些方法进行了较为全面的报道和简要的评论.
