病毒受体是病毒宿主范围和组织嗜性的一个决定因素。研究表明,4种整联蛋白αvβ1、αvβ3、αvβ6、αvβ8能够介导口蹄疫病毒感染偶蹄动物,且αvβ6是主要的口蹄疫病毒受体。首次从健康双峰驼肺组织中克隆到了β6亚基基因并进行了比较分析。结果显示,双峰驼β6基因的编码区含有2367个核苷酸,编码788个氨基酸残基,其中信号肽由26个氨基酸组成;胞外域由681个氨基酸组成,含有8个潜在的糖基化位点(NXT/NXS)和58个半胱氨酸(Cys)残基;跨膜区由29个氨基酸组成(708～736aa);胞浆域由52个氨基酸组成,含有一个NPLY核心基序和一个潜在的糖基化位点(NVT),该基因在GenBank中的登录号为EF613220。双峰驼β6基因与牛、猪、羊、人、小鼠、挪威大鼠β6基因的核苷酸序列同源性分别为91.1%、91.8%、90.6%、90.5%、83.7%、84.1%,推导的氨基酸序列同源性分别为94.3%、93.4%、93.4%、93.7%、88.7%、88.6%。偶蹄动物(双峰驼、牛、羊、猪)的β6基因同源性较高,在遗传进化树上同属于一个亚群,表明β6亚基可能与口蹄疫病毒的宿主范围有关。

Mammalian target of rapamycin(m TOR) inhibitor as an attractive drug target with promising antitumor effects has been widely investigated. High quality clinical trial has been conducted in liver transplant(LT) recipients in Western countries. However, the pertinent studies in Eastern world are paucity. Therefore, we designed a clinical trial to test whether sirolimus can improve recurrence-free survival(RFS) in hepatocellular carcinoma(HCC) patients beyond the Milan criteria after LT. This is an open-labeled, single-arm, prospective, multicenter, and real-world study aiming to evaluate the clinical outcomes of early switch to sirolimus-based regimens in HCC patients after LT. Patients with a histologically proven HCC and beyond the Milan criteria will be enrolled. The initial immunosuppressant regimens are center-specifc for the frst 4-6 weeks. The following regimens integrated sirolimus into the regimens as a combination therapy with reduced calcineurin inhibitors based on the condition of patients and centers. The study is planned for 4 years in total with a 2-year enrollment period and a 2-year follow-up. We predict that sirolimus conversion regimen will provide survival benefts for patients particular in the key indicator RFS as well as better quality of life. If the trial is conducted successfully, we will have a continued monitoring over a longer follow-up time to estimate indicator of overall survival. We hope that the outcome will provide better evidence for clinical decision-making and revising treatment guidelines based on Chinese population data.

junO is a multi-purpose neutrino observatory under construction in the south of *** publication presents new sensitivity estimates for the measurement of the △m_(31)^(2),△m_(21)^(2),sin^(2)θ_(12),and sin^(2)θ_(13) oscillation parameters using reactor antineutrinos,which is one of the primary physics goals of the *** sensitivities are obtained using the best knowledge available to date on the location and overburden of the experimental site,the nuclear reactors in the surrounding area and beyond,the detector response uncertainties,and the reactor antineutrino spectral shape constraints expected from the TAO satellite *** is found that the △m_(21)^(2) and sin^(2)θ_(12) oscillation parameters will be determined to 0.5%precision or better in six years of data *** the same period,the △m_(31)^(2) parameter will be determined to about 0.2%precision for each mass ordering *** new precision represents approximately an order of magnitude improvement over existing constraints for these three parameters.
