It is an important aspect of their sexual attractiveness, a sense of well being and a sense of self confidence. Vitiligo is an acquired depigmentation disorder of skin affecting 1% - 4% of the world population. Neither life threatening nor symptomatic (except that depigmented patches burn easily when exposed to the sun) the effects of vitiligo can be cosmetically and psychologically devastating. Because the disease is still not understood, there is a plethora of different treatments approaches, but they are largely unsatisfactory from patient’s perspective. Objective: To report the outcomes from oral use of an infusion of leaves of Solanum paniculatum L., Jacaranda brasiliensis and Sonchus oleraceus for treatment of vitiligo. Ethical issues: Study approved by the Research Ethics Committee of Hospital Federal dos Servidores do Estado do Rio de Janeiro (CAAE: 32143314.9.0000.5252). All participants confirmed the condition of volunteer by signing the Informed Consent Form. Methods: From October 2014 to October 2015 twelve subjects consumed daily four glasses (800 ml) of proposed phytotherapeutic preparation. Results: All subjects were highly satisfied about their outcomes. Total depigmentation was considered as a positive outcome because it is cosmetically acceptable. Total depigmentation was observed in presence of 80% or more of depigmenteted patches. Conclusions: The phytotherapeutic preparation proposed is effective on treatment of depigmenteted patches in vitiligo.展开更多
CBF类转录因子是调控植物冷害应答反应的关键因子。从蓝花楹中克隆到一个457 bp CBF类基因片段,序列分析表明其编码142氨基酸的片段,并与多个物种CBF1基因序列高度同源,且具有CBF家族的AP2核心结构域,因此将其命名为JaCBF1。原核表达的...CBF类转录因子是调控植物冷害应答反应的关键因子。从蓝花楹中克隆到一个457 bp CBF类基因片段,序列分析表明其编码142氨基酸的片段,并与多个物种CBF1基因序列高度同源,且具有CBF家族的AP2核心结构域,因此将其命名为JaCBF1。原核表达的结果显示此基因片段编码16 kDa的蛋白,表达分析结果显示JaCBF1于低温条件下在蓝花楹根、茎、叶中有差异性转录。Southern杂交结果揭示JaCBF1在蓝花楹基因组中存在至少2个拷贝。通过脓杆菌介导方法将JaCBF1异源转录到拟南芥中,荧光共聚焦显微照相结果显示其编码的蛋白质定位于细胞核,冷处理实验发现转基因拟南芥植株的耐冷性得到了显著提高,表明此新片段具有CBF类植物耐冷因子的典型功能。展开更多
