Preliminary studies on transgenic human IFN-γ gene in tobacco(转人γIFN基因烟草的初步研究)
Zhejiang Daxue xuebao. Lixue ban, 2000 以TA克隆法构建中间载体PUCF1,再构建γ干扰素基因表达载体PBIF1。通过农杆菌转化导入烟草叶圆片外植体。经4轮梯度卡那霉素(Kanamycin)递增筛选，获得抗性植株。经PCR证实其中部分植株已将人γ干扰素基因片段整合到烟草基因组中，从而为成功地建立烟草植物反应器生产人γ干扰素基因奠定了基础。

Integrative Conservation, Volume 5, Issue 1, Page 125-136, March 2026.We collated detections of the sun bear from new and previously published camera trap studies across its range. We then analysed these detections at two different spatial scales to assess the habitat associations and diel activity of this species. We found that the sun bear is tolerant to moderate habitat disturbances. ABSTRACT Degraded tropical forests,

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Emerging as attractive alternatives for sustainable, low‐cost, and high‐performance electromagnetic interference (EMI) shielding, biomass‐derived carbon is nonetheless constrained by a limited repertoire of shielding mechanisms. Herein, a straightforward method was employed to synthesize self‐supporting Co nanoparticles embedded in porous N ...

干扰素联合利巴韦林对慢性丙型肝炎患者血脂谱和胰岛素抵抗的影响
Zhongguo shiyan zhenduanxue, 2017 HCV感染不仅引起慢性肝炎、脂肪肝、肝硬化和肝癌等疾病,还可影响糖、脂代谢引起代谢性疾病[1]。干扰素（IFN）联合利巴韦林是慢性丙型肝炎抗病毒干预的标准方案之一。有报道,宿主胰岛素抵抗（IR）会降低HCV感染者对干扰素抗病毒干预的应答率,是影响干扰素抗病毒疗效的独立因素;干扰素干预也常出现血糖升高和胰岛素抵抗等临床表现[2 ...

干扰素治疗后病毒性肝炎病人#br# 干扰素中和抗体的检测及意义
Zhongshan Daxue xuebao. Yixue kexue ban, 1997 摘 要 使用4 种α-干扰素的98 例病毒性肝炎病人, 在治疗前、治疗期间及治疗后定期检测抗干扰素中和抗 体, 结果发现阳性率为34.7%, 该抗体的产生与病人的性别、年龄、治疗前ALT 水平、肝炎病毒感染类型、以及肝炎的 临床类型均无显著相关;低剂量干扰素较易产生中和抗体;使用不同干扰素制剂产生中和抗体存在差异, 其中以 rIFN-α2a 最高, IFN-αN1 最低;但中和抗体的出现对干扰素的抗病毒疗效影响不大, 由于病例数较少,干扰素治疗期间 ...
