Directional Liquid Transport in Thin Fibrous Matrices: Enhancement of Advanced Applications.

Directional liquid transport fibrous matrices (DLTFMs) have the unique ability to direct liquid movement in a single direction through their thickness. Beyond their inherent liquid transport function, DLTFMs can also enhance the effectiveness of additional functionalities. This review focuses on recent advances in DLTFMs, particularly the role of DLTs in enhancing secondary functions.

Latest insights into the epidemiology, characteristics, and therapeutic strategies of chronic hepatitis B patients in indeterminate phase.

As a hepatotropic virus, hepatitis B virus (HBV) can establish a persistent chronic infection in the liver, termed, chronic hepatitis B (CHB), which causes a series of liver-related complications, including fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). HCC with HBV infection has a significantly increased morbidity and mortality, whereas it could be preventable. The current goal of antiviral therapy for HBV infection is to decrease CHB-related morbidity and mortality, and achieve sustained suppression of virus replication, which is known as a functional or immunological cure.

Adipose-derived stem cells ameliorate radiation-induced lung injury by activating the DDAH1/ADMA/eNOS signaling pathway.

Background: Ionizing radiation-induced lung injury is caused by the initial inflammatory reaction and leads to advanced fibrosis of lung tissue.

Updates on global epidemiology, risk and prognostic factors of gastric cancer.

Gastric cancer (GC) is defined as the primary epithelial malignancy derived from the stomach, and it is a complicated and heterogeneous disease with multiple risk factors. Despite its overall declining trend of incidence and mortality in various countries over the past few decades, GC remains the fifth most common malignancy and the fourth leading cause of cancer-related death globally. Although the global burden of GC has shown a significant downward trend, it remains severe in certain areas, such as Asia.

Release of hepatitis B virions is positively regulated by glucose-regulated protein 78 through direct interaction with preS1.

In this study, we investigated the mechanism of hepatitis B virus (HBV)-enveloped particle release. Specifically, we used preS1 as a bait protein to screen host proteins using mass spectroscopy, with the results of immunofluorescence, western blot, co-immunoprecipitation, isothermal titration calorimetry, and pull-down assays identifying glucose-regulated protein (GRP)78 as a specific target for preS1 binding. We employed transcriptome sequencing, enzyme-linked immunosorbent assays, and particle gel assays to investigate the mechanism of GRP78-mediated positive regulation of HBV-enveloped particle release.

Immunomolecular assay based on selective virion capture by spike antibody and viral nucleic acid amplification for detecting intact SARS-CoV-2 particles.

Background: Effective therapeutics and vaccines for coronavirus disease 2019 (COVID-19) are currently lacking because of the mutation and immune escape of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Based on the propagation characteristics of SARS-CoV-2, rapid and accurate detection of complete virions from clinical samples and the environment is critical for assessing infection risk and containing further COVID-19 outbreaks. However, currently applicable methods cannot achieve large-scale clinical application due to factors such as the high viral load, cumbersome virus isolation steps, demanding environmental conditions, and long experimental periods.

Lipid metabolism analysis for peripheral blood in patients with alcoholinduced and steroidinduced osteonecrosis of the femoral head.

HDAC6/FOXP3/HNF4α axis promotes bile acids induced gastric intestinal metaplasia.

Bile reflux is one of the main causes of gastric intestinal metaplasia (IM) which is an important precancerous lesion. Our previous study has shown that ectopic expression of Histone deacetylase 6 (HDAC6) promotes the activation of intestinal markers in bile acids (BA) induced gastric IM cells; however, the mechanism underlying how HDAC6-mediated epigenetic modifications regulate intestinal markers is not clear. In this study, we aimed to investigate the downstream targets of HDAC6 and the underlying mechanism in the process of BA induced gastric IM.

The goal of this work was to study the impact of liposome sizes and the resulted drug distribution inside various skin tissue.

Pretreatment with metformin protects mice from whole-body irradiation.

Metformin, a first-line oral drug for type II diabetes mellitus, not only reduces blood glucose levels, but also has many other biological effects. Recent studies have been conducted to determine the protective effect of metformin in irradiation injuries. However, the results are controversial and mainly focus on the time of metformin administration.

The HBx and HBc of hepatitis B virus can influence Id1 and Id3 by reducing their transcription and stability.

Hepatitis B virus (HBV) infection is closely related with the occurrence and development of hepatocellular carcinoma (HCC), in which Hepatitis B virus x protein (HBx) and core protein (HBc) play crucial roles. Additionally, inhibitors of differentiation (Id) proteins exhibited significant correlation with liver cancer development. Here, we identified that HBV dramatically inhibited the expression of Id1 and Id3 in both protein and transcriptional levels for the first time, whereas there was little effect of the virus on Id2.
