Conclusion: These assays are suitable for routine diagnostic. The UltraFast NextGenPCR is the fastest with average time (30mins), followed by Agilent (2 hrs) and MassArray (6hrs). Upon completion of this activity, participants should be able to examine, measure and compare results from different assays for SARS detection, evaluate and diagnose accurately, as well as being able to plan, organize and recommend a diagnostic procedure for diagnostic laboratory. Key words: SARS-CoV-2, RNA extraction, RT-PCR, limit of detection, quantification cycle, COVID-19, in vitro diagnostic tests, Agilent, Massarray, Ultrafast. [20] From t...

Pharmacokinetics, Safety, and Tolerability of the siRNA JNJ ‐73763989 in Healthy Chinese Adult Participants
AbstractJNJ-73763989, composed of the 2 short-interfering RNA triggers JNJ-73763976 and JNJ-73763924, targets all hepatitis B virus messenger RNAs, thereby reducing all viral proteins. In this phase 1, single-site, open-label, parallel-group, randomized study, participants were given 1 subcutaneous injection of JNJ-73763989 (100 or 200 mg) to investigate the pharmacokinetics, safety, and tolerability of JNJ-73763989 in healthy Chinese adult participants. Plasma and urine pharmacokinetic parameters were determined for each trigger up to 48 hours after dosing. Eighteen participants, 9 per dose group, were enrolled. The me...

Screening of an epigenetic compound library identifies BRD4 as a potential antiviral target for hepatitis B virus covalently closed circular DNA transcription
In this study, we screened an epigenetic compound library in the cccDNA reporter cell line HepBHAe82, which produces the HA-tagged HBeAg in a cccDNA-dependent manner. Among the obtained hits, a bromodomain-containing protein 4 (BRD4) inhibitor MS436 exhibited marked inhibition of cccDNA transcription in both HBV stable cell line HepAD38 and HepG2-NTCP or primary human hepatocyte infection system under noncytotoxic concentrations. Chromatin immunoprecipitation (ChIP) assay demonstrated that MS436 dramatically reduced the enrichment of H3K27ac, an activating histone modification pattern, on cccDNA minichromosome. RNAseq diff...
