High-Throughput Screening of Antiviral Compounds Using a Recombinant Hepatitis B Virus and Identification of a Possible Infection Inhibitor, Skimmianine.

We developed a novel hepatitis B virus (HBV) infection-monitoring system using a luminescent, 11-amino acid reporter (HiBiT). We performed high-throughput antiviral screening using this system to identify anti-HBV compounds. After the infection of primary human hepatocytes with the recombinant virus HiBiT-HBV, which contains HiBiT at its preS1, 1262 compounds were tested in a first screening using extracellular HiBiT activity as an indicator of viral infection.

Functional involvement of endothelial lipase in hepatitis B virus infection.

Background: HBV infection causes chronic liver disease and leads to the development of HCC. To identify host factors that support the HBV life cycle, we previously established the HC1 cell line that maintains HBV infection and identified host genes required for HBV persistence.

Methods: The present study focused on endothelial lipase (LIPG), which binds to heparan sulfate proteoglycans (HSPGs) in the cell membrane.

Prediction of delayed union of tibial shaft fracture treated with intramedullary nailing: multicenter-study analysis and literature review -the TRON study.

Purpose: We aimed to 1) identify predictors of delayed and nonunion of tibial shaft fractures in patients treated with intramedullary nailing (IMN), including patient demographics and surgical factors, and 2) determine whether the nail/shaft ratio is associated with delayed and nonunion.

Methods: This retrospective, multicenter study included 315 patients with tibial shaft fracture treated with IMN between 2014 and 2019 and excluded patients with insufficient follow-up for 12 months, lost data and inadequate radiographs. Finally, we analyzed 258 patients (184 males; 74 females).

Early versus delayed weight bearing after intramedullary nailing for tibial shaft fracture: A multicenter, propensity score-matched study, the TRON study.

Objectives: The purpose of this multicenter study was to assess the differences in the rates of implant failure and bone union by X-ray examination, and walking ability between an early weight-bearing group (EWB) and a non-weight-bearing group (NWB) following treatment with intramedullary nailing (IMN) for tibial shaft fractures with a propensity score-matching method.

Material And Methods: We collected data from 336 patients with tibia fractures that were treated surgically. We excluded patients lost to follow-up and polytrauma patients.

Flower color mutation caused by spontaneous cell layer displacement in carnation (Dianthus caryophyllus).

A change of layer arrangement of shoot apical meristem (SAM) organized by three cell layers (L1, L2 and L3) is thought to be one of the provocations of bud sport, which often induces changes in phenotypic colors in periclinal chimeras. This paper describes a cell layer rearrangement which is the cause of spontaneous flower color mutation by using two carnation (Dianthus caryophyllus L.) cultivars that are presumably periclinal chimeras, 'Feminine Minami' (deep pink flower) and its recessive sport 'Tommy Minami' (pinkish red flower).
