Study on toxic effect of alkyl phenanthrenes and the influence of humic acid on the bioavailability of them [PDF]
, 2015 烷基取代多环芳烃（AlkylPolycyclicAromaticHydrocarbons，AlkylPAHs）作为环境中PAHs的重要组成部分，因其毒性效应强、种类繁多，且与母环PAHs（ParentPolycyclicAromaticHydrocarbons，ParentPAHs）致毒机理差异显著已逐步成为研究热点。然而，多数毒理学研究忽略了实际环境因素对烷基取代PAHs生物有效性的影响。本研究首先从形态学指标（心脏拉长、心率、孵化率和孵化时间）、生化指标（SOD、CAT活力及MDA水平 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Many existing rubrics for L2 argumentative writing prioritize form‐based linguistic accuracy and complexity while insufficiently addressing substantive argumentative rigor and effectiveness. This limitation is further complicated by cross‐cultural variation in rhetorical conventions and educational practices, which challenge the direct ...

野生动物学报, 2012 南非海狮是目前国内外动物园、水族馆中饲养比较普遍的动物,但经常出现一些细菌性、病毒性和寄生虫等疾病,在海狮健康状况监测和疾病诊断中需要有生理生化指标正常值作为参考。但目前南非海狮的正常生理生化指标报道较少。杭州动物园先后对6只成年南非海狮进行采血,共收集20个（12雄8雌）血液常规样本测定了15项主要生理指标和6个（4雄2雌）血清生化标本对18项主要生化指标进行检测。在测定项目中WBC、RBC、MCH、MCV、RDW、HCT、MPV、PCT、ALT、TP、ALB、TBIL、GLU、Ca2+、Pi、Mg2+

Detoxification and Antioxidant Defence of Marine Medaka(Ozyzias melastigma) Liver against Hexavalent Chromium Exposure [PDF]
, 2016 近年来，随着工业化进程的深入和沿海城市化的发展，工农业和城市生活污水的排入，导致近海海域铬污染问题日益严重，对海洋生物生存和人类健康造成了危害。海洋青鳉鱼(Oryziasmelastigma)因其对水质、环境变化敏感，被广泛应用于海洋污染物的毒理学研究中，是一种新兴的海洋生态毒理学模式生物。为探究海洋鱼类对六价铬暴露的抗氧化防御、解毒机制，本论文以海洋青鳉鱼成鱼肝脏、幼鱼为材料，进行了初步探讨。得到以下结果： （1）以3月龄海洋青鳉鱼成鱼进行Cr6+暴露试验，试验组Cr6+浓度设置为2.6lmg/L、5.

Journal of Sociolinguistics, EarlyView.ABSTRACT This study adopts a transnational raciolinguistic perspective to examine how Chinese international students (CISs) navigate language, race, and identity across borders and contexts. Based on semistructured interviews with 14 CISs, the study highlights that pre‐migration socialization in China influences how CISs perceive and interpret their ...

Zhongguo shiyan zhenduanxue, 2011 目的探讨脑脊液生化指标监测对胸腹主动脉夹层术后脊髓缺血损害判断的临床意义。方法将50例胸腹主动脉夹层手术患者根据术后是否发生脊髓缺血损害并发症分成损伤组（SCI组,n=5）和无损伤组（NSCI组,n=45）。术前、术后分7个时点对脑脊液取样,对胶质纤维酸蛋白（GFAP）、S100β蛋白以及神经丝蛋白亚单位（NFL）等3个生化指标进行测定。比较分析上述3个生化指标在2组之间的变化。将无脊髓损伤患者据术式分为血管置换手术组（AR组,n=9）和腔内隔绝术组（EVGE组,n=36 ...

Experimental Study on the Effect of “CiJi regimen for curing cancers”on Gastrointestinal Function of Tumor Chemotherapy Model Mouse [PDF]
, 2015 目的：当前，肿瘤发病率有上升的趋势，严重威胁人们的身体健康。化疗是现代医学治疗肿瘤的主要手段之一。而化疗药物在许多患者身上出现了较明显的毒副反应，且其远期疗效不容乐观。患者复发率偏高、生存质量下降的问题较为突出。而且西医在化疗后的配套治疗上尚无令人满意的手段，大多在患者病情暂时缓解后采取“等待观察”的办法。由于化疗并不能完全消灭所有的肿瘤细胞，故而这一办法虽然使患者有一个“休养生息”的机会，同时也埋下了肿瘤“卷土重来”的隐患。因此，在化疗后的治疗环节上，选择合适的治疗方式和个性化的治疗方案是有意义的 ...
