在最近进行的尿检中发现:邻苯二甲酸盐(Phthalates)的含量比以前预想的要高。而Phthalates are used as stabilizer(稳定剂)in cosmetics and softeningagents in plastics like polyvinyl([化]乙烯聚合物的)chloride(氯化物)(PVC)。这就值得引起我们的密切注意。这些毒物残留在人体内时,会导致何种疾病,尚有待探究:The only questionremaining is what types of illnesses might be related to the exposure。然而,有一点是肯定的,我们所熟悉的PVC应该停止使用: In 1997,Greenpeace(保护动物不遭捕猎等的绿色和平组织)testedchildren’s toys and identified five of the seven phthalates mentioned in the currentCDC *** has since called for an international phase out(逐步停止使用)of PVC。

大脑是人的行为和情绪的司令部。这则报道让我们了解大脑不同的部位有不同的“辖区”,比如,热恋中的人,大脑的limbic(边缘的)region就容易被激活,而反之,有的部位,如the neocortex([解]新[大脑]皮层)就会活动减慢。文章的末尾提出了一... 详细信息

大脑是人的行为和情绪的司令部。这则报道让我们了解大脑不同的部位有不同的“辖区”,比如,热恋中的人,大脑的limbic(边缘的)region就容易被激活,而反之,有的部位,如the neocortex([解]新[大脑]皮层)就会活动减慢。文章的末尾提出了一个天真而又幼稚的问题: so does this mean that we can all hope for a drug that will rekindle dying flames of love? 假如这种药物真正来到人间,那么,白发苍苍的老者将在心中重新点燃爱之烈焰,是喜,是忧,还是悲?】

Tissue engineering(TE)continues to be widely explored as a potential solution to meet critical clinical needs for diseased tissue replacement and tissue *** this study,we developed a poly(2-hydroxyethyl methacrylate-co-methacrylic acid)(pHEMA-co-MAA)based hydrogel loaded with newly synthesized conductive poly(3,4-ethylene-dioxythiophene)(PEDOT)and polypyrrole(PPy)nanoparticles(NPs),and subsequently processed these hydrogels into tissue engineered constructs via three-dimensional(3D)*** presence of the NPs was critical as they altered the rheological properties during ***,all samples exhibited suitable shear thinning properties,allowing for the development of an optimized processing window for 3D *** were 3D printed into pre-determined disk-shaped configurations of 2 and 10 mm in height and diameter,*** observed that the NPs disrupted the gel crosslinking efficiencies,leading to shorter degradation times and compressive mechanical properties ranging between 450 and 550 *** conductivity of the printed hydrogels increased along with the NP concentration to(5.10±0.37)×10^(−7)s/*** vitro studies with cortical astrocyte cell cultures demonstrated that exposure to the pHEMA-co-MAA NP hydrogels yielded high cellular viability and proliferation ***,hydrogel antimicrobial studies with staphylococcus epidermidis bacteria revealed that the developed hydrogels affected bacterial *** together,these materials show promise for various TE strategies.
