Ca-efflux,from direct membrane injury by CCl4, is elicited by amphiphilic vehicles in vitro

Direct membrane injury by CCl₄, in situations excluding metabolic activation, was evaluated in saponin-permeabilized hepatocytes and in microsomes by measuring immediate Ca²⁺ efflux. A good correlation appears between the Ca²⁺ efflux and the level of CCl₄ in the membrane and also the variations in fluidity. Mixtures of CCl₄ with water-soluble vehicles were used to improve the dispersion of CCl₄ in the medium. The mixtures varied in their ability to elicit the membrane effects of CCl₄. The performance of ethanol and, to a lesser degree, other alcohols, suggests the existence of a water stable structural organization between CCl₄ and these amphiphilic vehicles, facilitating the transfer of CCl₄ to the membrane.

Comparisons of low carbon policies in supply chain coordination

This paper investigates the influence of low-carbon policies on channel coordination for a two-echelon supply chain consisting of one supplier and one retailer. Four different models are considered： the basic model, the carbon emission model, the carbon emission trading model and the carbon tax model. We find that the government policy on all carbon emission models is not universal among the firms as well as the customers. The carbon emission trading policy is always better than the carbon emission policy and the carbon tax policy when the allocated carbon emission quotas are greater than the carbon emissions. The carbon emission trading policy is proved to be an effective mechanism which can motivate the supply chain to reduce carbon emissions. Under certain conditions, the supply chain prefers the carbon emission trading policy with higher carbon price to other policies. In the framework of Stackelberg game with the supplier as the leader, for each carbon policy, the paper presents coordination mechanism with the all-unit wholesale quantity discount contract （AWQD）. We analyze and compare the influence of low-carbon policies on channel coordination for the foul＂ low-carbon policies. Numerical experiments are conducted to examine our findings.     

水中痕量镉的曙红Y-中性红能量转移荧光猝灭法测定

在pH 7.9的BR缓冲液中,曙红Y-中性红和镉离子相互作用,在535 nm处荧光强度随着镉浓度的增加,体系的荧光逐渐降低,其荧光强度降低值和镉离子含量在一定范围内有相关关系.据此建立了一种测定痕量镉的曙红Y-中性红体系能量转移荧光猝灭新方法,并优化了实验条件.在优化的实验条件下,体系在535 nm处的荧光强度降低值与镉的摩尔浓度在1.6＆#215;10-8~3.2＆#215;10-6 mol/L范围内线性关系良好,其线性回归方程为：？F=936.60-2425.2c（＆#215;10-6mol/L）,相关系数r=0.998,检出限为4.7＆#215;10-9 mol/L,相对标准偏差是0.45%,加标回收率是90.75%.本方法操作简便、灵敏、选择性好,用于实际样品中镉的测定,其测定结果同石墨炉原子吸收法一致（t检验法）.
