    • Wildtype and mice lacking the gene encoding PKCI/HINT 1 (PKC -/- ) were used to assess the involvement of PKCI/HINT1 in regulating basal locomotor activity and the behavioral activating effects of the psychostimulant, amphetamine. PKCl -/- mice displayed low level of spontaneous locomotion relative to WT littermates. Acute administration of amphetamine significantly increased locomotor activity in WT mice; an effect that was enhanced in PKCl -/- mice. Microdialysis studies revealed no alteration in basal DA dynamics in the striatum and nucleus accumbens of KO mice. Similarly, the ability of acute amphetamine to increase DA levels in these brain regions was unaltered. However, a dopamine receptor agonist, apomorphine (10mg/kg), was able to induce a significantly higher locomotor activity in PKCI -/- mice as compared with WT, suggesting there may be a dopaminergic functional change at the postsynaptic site. Our results also revealed that PKCI KO mice showed a less depression and anxiety trait than their litter mate controls (WT), which indicate that PKCI could also play a role in regulating the emotion states of brain. Together, these results indicated that PKCI/HINT1 may have a suppressive role in normal DA neurotransmission, and may also play an important role for the action of psychostimulants in schizophrenia.
    • 使用缺乏编码PKCI / HINT1(PKC - / - )的基因的野生型和小鼠来评估PKCI / HINT1参与调节基础运动活性和精神兴奋剂苯丙胺的行为活化作用。 小鼠相对于WT同窝出生者显示出低水平的自发运动。 安非他明的急性给药显着增加WT小鼠的运动活性; 在PKC1 小鼠中增强的作用。 微透析研究显示KO小鼠的纹状体和伏隔核中的基础DA动力学没有改变。 类似地,急性苯丙胺胺在这些脑区域中增加DA水平的能力是未改变的。 然而,与WT相比,多巴胺受体激动剂阿朴吗啡(10mg / kg)能够诱导PKC1 - / - 小鼠的运动活性显着更高,这表明可能存在多巴胺能功能变化 突触后位点。 我们的研究结果还表明,PKCI KO小鼠的凋亡抑制和焦虑特征比其凋零物质控制(WT)低,这表明PKCI也可以在调节脑的情绪状态方面发挥作用。 这些结果一起表明,PKCI / HINT1可能在正常DA神经传递中具有抑制作用,并且也可能对精神分裂症患者精神分裂症的作用起重要作用。

    • Heterocyclic and acyclic silane monomers and siloxane polymers, and their halogenated derivatives, are provided for the purpose of functionalizing surfaces or materials so as to render them biocidal upon exposure to oxidative halogen solutions.The biocidal function can be imparted either before or after bonding or adhesion to the surface or material. The biocidal surfaces and materials can then be used to inactivate pathogenic microorganisms such as bacteria, fungi, and yeasts, as well as virus particles, which can cause infectious diseases, and those microorganisms which cause noxious odors and unpleasant coloring such as mildew.
