横穿的精神或精神分裂

法国当代哲学家德勒兹和精神分析学家费利克斯加达里合写了一本“非哲学史”的“哲学”著作《千座平台》,这也是一本后现代主义哲学的代表作品。书中把所有精神事件看成是发生在分子或基因水平上的,出现在不同的精神空间。这样的立场,不啻一场哲学革命,因为它导致了与传统形而上学不同的“横穿的精神”或精神分裂。     

关于授予基因专利的伦理与立法讨论--从美国专利法授予基因专利谈起

文章通过从美国授予基因专利的实例及引发的争论着手,分析了专利法在捍卫人类伦理与推动基因研发两方面所能起到的作用,并针对当今世界的立法趋势提出了一些建议.     

论基因平等权

基因平等权是一项与科学权力相关的人类权利 ,是指非正常基因携带者应当在学习、就业等社会生活中享有与正常人同等的权利 ,不应受到任何歧视。目前它具有技术依赖性和主体广泛性两个基本特征。我国应从制度和立法上保障公民的基因平等权     

Forensic value of 14 novel STRs on the human Y chromosome

We identified and characterized 14 novel short-tandem-repeats (STRs) on the Y chromosome and typed them in two samples, a globally diverse panel of 73 cell lines, and 148 individuals from a European–American population. These Y-STRs include eight tetranucleotide repeats (DYS449, DYS453, DYS454, DYS455, DYS456, DYS458, DYS459, and DYS464), five pentanucleotide repeats (DYS446, DYS447, DYS450, DYS452, and DYS463), and one hexanucleotide repeat (DYS448). Sequence data were obtained to designate a repeat number nomenclature. The gene diversities of an additional 22 Y-STRs, including the most commonly used in forensic databases, were directly compared in the cell line DNAs. Six of the 10 most polymorphic markers include the newly identified Y-STRs. Furthermore, these novel Y-STRs greatly improved the resolution of paternal lineages, above the level obtained with commonly used Y-STRs, in the European–American population.     

Gc、Tf和C_3表型的同步检测

血清蛋白多态性的同步检测可节省检材、简化操作步骤、省时省力.本文用醋酸纤维素薄膜电泳免疫固定法同步检测血清型特异成份(Group-Specific component,Gc)、转铁蛋白(Transferrin,Tf)和补体第三成份(Complment 3,C_3)的表型,调查了成都地区汉族116名无亲缘关系的健康献血员的表型频率,现将结果报导如下:     

The esterase D polymorphism as revealed by isoelectric focusing in ultra-thin polyacrylamide gels

The polymorphism of human red cell esterase D (EsD) was studied using isoelectric focusing (pH 4-6) in ultra-thin polyacrylamide gels. Typing was possible without the EsD isozymes attaining true equilibrium focusing conditions. Using this single method, six phenotypes (EsD 1, 2-1, 2, 5-1, 5-2 and 5) could be recognized in the White population of south-east England. Family studies showed these to be controlled by three co-dominant alleles and the gene frequencies were calculated to be EsD1 0.8856; EsD2 0.0946 and EsD5 0.0198. For successful and reliable EsD typing by this method, the electrophoretic system must be carefully optimized with respect to the duration of electrophoresis and the temperature attained in the gel during the electrophoretic run.     

基因多态性、饮酒种类与乙醇代谢的相关性CSCD

目的探索ADH1B和ALDH2基因多态性以及饮酒种类对乙醇代谢的影响,为司法鉴定实践中涉及乙醇代谢结果解释或对血乙醇含量回推的案件提供数据支持。方法筛选出81名志愿者,通过多重SNa Pshot分型方法获得ADH1B、ADH1C和ALDH2的基因型。饮酒剂量为1.0 g/kg,在饮酒前以及饮酒后30 min、45 min、1 h、1.5 h、2 h、3 h、4 h、5 h、6 h、7 h和8 h静脉采血1 m L,通过顶空气相色谱法检测血中乙醇和乙醛的浓度,计算血乙醇达峰时间(T_(max))、乙醇峰值质量浓度(C_(max))、乙醇曲线下面积(area under curve,AUC_(乙醇))、AUC_(乙醛)和乙醇消除斜率(β)。为排除ADH1C基因多态性的干扰,选择携带ADH1C*1/*1基因型的个体,根据ADH1B和ALDH2的基因型分组,对各组上述参数进行单因素方差分析,并运用最小显著差异法进行组间比较,基因间的相互作用关系采用双因素方差分析。对3种饮酒种类(白酒、红酒和啤酒)组间的各参数进行随机区组设计方差分析。结果不同ADH1B和ALDH2基因型组间T_(max)和C_(max)差异无统计学意义,部分基因型组间AUC_(乙醇)、β和AUC_(乙醛)差异有统计学意义。个体饮相同剂量不同种类酒时,各组间各参数差异均无统计学意义。结论乙醇代谢受相关基因多态性影响较大,基本不受饮酒种类的影响。
