Hobbyist preferences for pet freshwater turtles
Abstract The burgeoning pet trade is a primary threat to wild freshwater turtles worldwide. Although the risks from commercial exploitation of turtles have been discussed widely, there is little empirical research on preferences for pet turtles from a hobbyists’ perspective.

Abstract Consumer demand for ivory perpetuates the unsustainable and illegal killing of African elephants and other wildlife species. Interventions that aim to change consumer behavior are increasingly recognized as a crucial element of demand management. However, poor design and implementation have limited their effectiveness.

Abstract Wildlife reintroductions are socioecological processes entailing the intentional movement of organisms by people. In animal reintroductions, there is growing recognition of the importance of human dimensions and efforts to integrate these into reintroduction projects. To conceptually reframe reintroductions as processes of renewed coexistence (

血管紧张素转换酶、内皮型一氧化氮合酶和载脂蛋白E基因多态性与冠心病的相关性
[目的]研究血管紧张素转换酶(ACE)基因插入/缺失多态性、内皮型一氧化氮合酶(eNOS)基因G894T多态性和载脂蛋白E(ApoE)基因多态性与冠状动脉粥样硬化性心脏病(冠心病)的关系.[方法]应用基因芯片技术分析133例冠心病患者和122例对照者ACE、eNOS和ApoE基因多态性,对比两组基因型及等位基因频率.[结果]冠心病组ACE DD基因型频率比对照组显著升高,28.6% vs 13.1%,P<0.01,ACE基因多态性与冠心病危险性相关.两组eNOS和ApoE基因型频率差异无统计学意义(P ...

烧伤创面内表皮生长因子、表皮生长因子受体、C-myc三种基因表达变化的临床观察
目的为探讨烧伤创面愈合机理,了解烧伤创面内表皮生长因子基因、表皮生长因子受体基因和C-myc基因的变化,为临床治疗提供依据。方法我们对25例病人烧伤创面的不同部位应用原位杂交方法,观察表皮生长因子基因、表皮生长因子受体基因和C-myc基因在烧伤创面肉芽中心部(肉芽中心部)、肉芽与愈合皮肤的交界部(创面交界部)、愈合皮肤部位(创面愈合部)和自身正常皮肤对照部位内表达强度和分布的特点。结果同一部位烧伤创面内,表皮生长因子基因和C-myc基因在交界部表达最强;烧伤创面中心部位表达次之,烧伤创面愈合部位表达较弱;

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

目的探讨大肠肿瘤p53和ki-ras基因协同突变的临床意义。方法采用免疫组化和PCR-SSCP方法,检测58例大肠肿瘤患者的良性病变、良性病变转为恶变、原发腺癌组织的p53基因、ki-ras基因的表达和突变情况。结果良性病变组与恶变组间的p53基因和Ki-ras基因的表达有显著差异,良性病变组与原发腺癌组的Ki-ras基因表达差异显著;良性病变组的p53基因与Ki-ras基因的表达呈负相关,而恶变组和原发腺癌组呈正相关。p53基因和ki-ras基因两种基因突变率无显著差异,而协同突变与淋巴结转移密切相关,
