Study on Multicolor Melting Curve Analysis-based Approaches for the Detection of Gene Polymorphisms Related to Pharmacogenomics [PDF]

open access: yes, 2017
个体间药物响应的差异性长期困扰着临床,不同病人对同样剂量的同种药物所表现出的疗效和毒副作用往往不同。药物基因组学研究表明,基因多态性对个体药物响应差异起主导作用。伴随药物基因组学的深入研究,药物基因组生物标记物也不断被发现。基因检测是实现个体化用药的重要手段,通过检测相关基因多态性,可指导临床个体化用药,从而提高药物疗效和降低药物不良反应。本文将多色探针熔解曲线分析技术用于药物代谢酶基因CYP2D6、DPYD,药物转运体基因SLCO1B1,药物作用靶点基因ADRB1、APOE、ANKK1 ...

Functional homogenization of terrestrial mammals outside protected areas in the Hengduan Mountains, China

open access: yesConservation Biology, EarlyView.
Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

脂联素基因SNPs-11377C/G多态性与女性乳腺癌的相关性

open access: yesZhongguo shiyan zhenduanxue, 2015
目的探讨脂联素基因SNPs-11377C/G多态性与女性乳腺癌发生的相关性。方法用聚合酶链式反应-限制性内切酶长度多态性(PCR-RFLP)技术观察脂联素基因在不同人群中的单核苷酸多态性,其中包括乳腺癌组患者70人,健康对照组30人。结果 SNPs-11377C/G等位基因频率在乳腺癌和正常对照组间分布差异无统计学意义(P>0.05),乳腺癌患者组CG基因型分布频率高于GG型和对照组相比差异有统计学意义 ...

Using incentive payments to promote human–carnivore coexistence

open access: yesConservation Biology, EarlyView.
Abstract For many large carnivores, minimizing the financial burden they impose on local people is critical to their conservation. Incentive‐based programs that provide people with financial benefits for taking pro‐conservation actions or achieving conservation goals are a promising tool for promoting human–carnivore coexistence. Although the number of

Molecular mechanism of inhibitory effect of lipoxin A4 on estrogen-induced epithelial to mesenchymal transition (EMT) in endometriosis [PDF]

open access: yes, 2016
子宫内膜异位症,简称内异症(Endometriosis,EM),是育龄妇女的常见病,它是指具有活性的子宫内膜出现在子宫腔以外所引起的一种病变。人群发病率高达10%-15%。其典型症状为不孕和疼痛,严重影响患者的生活质量和家庭和谐,尤其是高达50%的复发率,给家庭和社会带来沉重的经济负担。这一系列防治难题的根本原因在于发病机制尚不明确。解析内异症的发病机制,进而寻找新的药物靶点和安全高效的治疗方法具有重大意义。 本论文首先以临床内异症患者在位/异位子宫内膜组织及非内异症患者子宫内膜组织为研究对象 ...

白细胞介素16基因多态性与食管鳞癌的相关性

open access: yesZhongguo shiyan zhenduanxue, 2013
目的探讨白细胞介素16(Interleukin-16,IL-16)基因多态性与食管鳞癌的关联。方法采用聚合酶链反应-限制性片段长度多态性方法检测IL-16基因多态性在188例健康对照组和155例食管鳞癌组中的分布,并分析其与临床特征的相关性。结果 rs11556218TG基因型在食管鳞癌组中的频率明显高于其在对照组中的频率(54.8%比42.6%,χ2=6.02,P=0.014);rs11556218G等位基因在食管鳞癌组中的频率明显高于其在对照组中的频率(32.6%比25.0%,χ2=4.80,P=0.
