[Abstract]  The here described method can be used to estimate the uptake of orally provided cholesterol in mice. Briefly, mice are gavaged with radiolabeled cholesterol and 4 h later, organ distribution of the radiolabel is determined by liquid scintillation counting. The method has been applied successfully to determine dietary cholesterol handling of mice housed at different ambient temperatures [摘要]  这里描述的方法可用于估计小鼠口服提供的胆固醇的摄取。 简而言之,用放射性标记的胆固醇强饲小鼠,4小时后,通过液体闪烁计数测定放射性标记的器官分布。 该方法已成功应用于确定在不同环境温度下饲养的小鼠的膳食胆固醇处理

【背景】胆固醇促进膜的流动性,并且是类固醇激素,胆汁酸和维生素D的前体。动物通过饮食或通过 de novo 合成提供胆固醇。胆固醇的过剩可能是有害的,因为它在血管壁中的积累可导致动脉粥样硬化。已经表明,通过冷处理棕色脂肪组织(BAT)可以降低高胆固醇血症(Berbee 等,,2015)。然而,尚不清楚最佳可行技术活动是否会改变急性外周膳食胆固醇处理。为了解决这个问题,我们口服给予小鼠富含重组富含甘油三酯的脂蛋白颗粒(rTRL),用[4- 14 C] - 胆固醇标记,并在管饲后4小时测量放射性标记的器官分布。之前已经测量了放射性标记的胆固醇体内的生物分布(Szigeti 等,,1972; Townsend et al。,2001)。然而,在这些研究中,放射性胆固醇由饮食提供或静脉注射。此外,其他研究评估了较长时间内(48和72小时)的胆固醇吸收率(Zilversmit和Hughes,1974; Turley et ...

Infectious Virus Yield Assay for Hepatitis E Virus

[Abstract]  Hepatitis E virus (HEV) is one of the main causes of acute hepatitis worldwide. Infections are particularly severe in pregnant women and chronic hepatitis E is known to occur in immunocompromised patients. Current therapy (ribavirin or pegylated alpha interferon) has severe side effects and cannot be employed in all patients. In order to evaluate potential new inhibitors of HEV replication, a virus yield assay can be employed in which the amount of viral RNA progeny released into the culture medium is quantified by reverse-transcription quantitative PCR (RT-qPCR) (Debing et al., 2014).
[摘要]  戊型肝炎病毒(HEV)是全世界急性肝炎的主要原因之一。 感染在孕妇中特别严重,已知慢性戊型肝炎发生在免疫受损的患者中。 目前的治疗(利巴韦林或聚乙二醇化α干扰素)具有严重的副作用,不能用于所有患者。 为了评估潜在的新的HEV复制抑制剂,可以使用病毒产量测定法,其中释放到培养基中的病毒RNA子代的量通过逆转录定量PCR(RT-qPCR)(Debing等人, al 。,2014)。

[Abstract]  Hepatitis E virus (HEV) is one of the main causes of acute hepatitis worldwide. Infections are particularly severe in pregnant women and chronic hepatitis E is known to occur in immunocompromised patients. Current therapy (ribavirin or pegylated alpha interferon) has severe side effects and cannot be employed in all patients. In order to evaluate potential new inhibitors of HEV replication, a luminescence-based replicon assay is particularly useful since it offers a rapid read-out and does not pose any biosafety risks (Debing et al., 2014).
