A revamped rat reference genome improves the discovery of genetic diversity in laboratory rats.

The seventh iteration of the reference genome assembly for Rattus norvegicus-mRatBN7.2-corrects numerous misplaced segments and reduces base-level errors by approximately 9-fold and increases contiguity by 290-fold compared with its predecessor. Gene annotations are now more complete, improving the mapping precision of genomic, transcriptomic, and proteomics datasets.

Geographic Differences on Clinical Manifestations of COVID-19 Infection Between Overseas Chinese and Local Chinese Patients.

Introduction: The novel coronavirus (COVID-19) has become a global pandemic with sharp rises in the number of confirmed cases and rapid spread across the world. Here, we looked at the effects of geographic differences on clinical manifestations of SARS-CoV-2 infected patients.

Methods: A total of 114 confirmed COVID-19 patients were included in this study.

Immunological Evaluation on Potential Treatment Window for Hospitalized COVID-19 Patients.

Purpose: Novel coronavirus disease has become such an escalating epidemic that the exponential growth of infected patients has overloaded the health-care systems in many countries. Determination of early assessments for patients with a risk of clinical deterioration would benefit the management of COVID-19 outbreaks.

Patients And Methods: A total of 214 confirmed COVID-19 patients were enrolled from January 11th to February 11th 2020.

Combination of saikosaponin c and telbivudine synergistically enhances the anti-HBV activity.

Objective: The present study was undertaken to obtain data using the combination of SSc and lamivudine (LAM), entecavir (ETV) or telbivudine (LdT) in HepG2.2.15 cells to explore whether SSc acts as a potent adjuvant of nucleoside analogues in anti-HBV treatment.

Polymerase Chain Reaction Assays Reverted to Positive in 25 Discharged Patients With COVID-19.

We report the observation that 14.5% of COVID-19 patients had positive RT-PCR testing again after discharge. We describe correlations between laboratory parameters and treatment duration (P = .

The correlation between viral clearance and biochemical outcomes of 94 COVID-19 infected discharged patients.

Objective: This study aims to evaluate the correlation between viral clearance and blood biochemical index of 94 discharged patients with COVID-19 infection in Shenzhen Third People's Hospital, enrolled from Jan 5 to Feb 13, 2020.

Methods: The clinical and laboratory findings were extracted from the electronic medical records of the patients. The data were analysed and reviewed by a trained team of physicians.

Hydrophilic Porous Poly(l-Lactic Acid) Nanomembranes: Self-Assembly, and Anti-Biofouling and Anti-Thrombosis Effects.

Hydrophilic PEGylated porous self-assembled nanomembranes (PSANMs) with average thickness and pore diameter of ca. 10 and 20-24 nm were successfully prepared by an emulsification-induced programmable self-assembly strategy. The hydrophilicity, anti-biofouling, and anti-thrombosis properties of PEGylated PSANMs were largely improved in comparison with the nonfunctionalized PSANMs, which could transform into hydrophilic (PEGylated PSANMs, minimum water contact angle: 38.

Saikosaponin C exerts anti-HBV effects by attenuating HNF1α and HNF4α expression to suppress HBV pgRNA synthesis.

Objective: Saikosaponin c (SSc), a compound purified from the traditional Chinese herb of Radix Bupleuri was previously identified to exhibit anti-HBV replication activity. However, the mechanism through which SSc acts against HBV remains unknown. In this study, we investigated the mechanism of SSc mediated anti-HBV activity.

Folate Receptor-Mediated Renal-Targeting Nanoplatform for the Specific Delivery of Triptolide to Treat Renal Ischemia/Reperfusion Injury.

Triptolide (TP) has been widely used in clinical medicine; however, it has created a dilemma due to its toxicity and nonspecificity. Here, we reported a biocompatible and high-efficiency renal-targeting nanoplatform for renal ischemia/reperfusion injury (IRI) therapy, in which the toxic drug of TP was encapsulated into folate (FA)-modified Pluronic F127/P123 nanoparticles (FPNPs). The TP-loaded FPNPs (TP-FPNPs) had good stability and could effectively reduce the cytotoxicity of TP.

Molecular analysis of a large novel deletion causing α-thalassemia.

Background: α-thalassaemia is an inherited blood disorder caused by mutations in the α-globin gene cluster. Recognizing the pathogenic α-globin gene mutations associated with α-Thalassemia is of significant importance to thalassaemia's diagnosis and management.

Methods: A family with α-thalassaemia from Fujian, China was recruited for this study.

Resveratrol Exerts Antioxidant Effects by Activating SIRT2 To Deacetylate Prx1.

Resveratrol is a promising chemical agent that treats multiple aging-related diseases and improves life span. While reactive oxygen species undoubtedly play ubiquitous roles in the aging process and resveratrol has been shown to be an effective antioxidant, the mechanism through which resveratrol acts against oxidative stress remains unknown. Here we show that resveratrol activates SIRT2 to deacetylate Prx1, leading to an increased HO reduction activity and a decreased cellular HO concentration.

Significant enhancement of hPrx1 chaperone activity through lysine acetylation.

The reversible acetylation of proteins plays a key role in regulating biological processes, including chromatin remodeling, progression of the cell cycle, and actin nucleation. Human peroxiredoxin 1(hPrx1), one of the most abundant proteins in the cytoplasm, has been shown to be acetylated in human liver-carcinoma tissues. However, little is known about what function(s) the acetylation serves for hPrx1.

Genetically encoded cyclopropene directs rapid, photoclick-chemistry-mediated protein labeling in mammalian cells.

We just click: Genetic incorporation of a cyclopropene amino acid CpK (see scheme) site-specifically into proteins in E. coli and mammalian cells was achieved using an orthogonal aminoacyl-tRNA synthetase/tRNA(CUA) pair (CpKRS/MbtRNA(CUA)). Cyclopropene exhibited fast reaction kinetics in the photoclick reaction and allowed rapid (ca.
