Bioinformatics and experimental validation were combined to explore lactylation-related biomarkers in HBV-associated acute liver failure.

Background And Aim: Currently, hepatitis B virus-related acute liver failure (HBV-ALF) has limited treatment options. Studies have shown that histone lactylation plays a role in the progression of liver-related diseases. Therefore, it is essential to explore lactylation-related gene (LRGs) biomarkers in HBV-ALF to provide new information for the treatment of HBV-ALF.

Four-dimensional evaluation and forecasting of marine carrying capacity in China: Empirical analysis based on the entropy method and grey Verhulst model.

This study separates marine carrying capacity into four key dimensions, i.e., social, economic, resource, and ecological, and uses the entropy method to evaluate the carrying capacity of China's 11 coastal regions during the period 2007-2016.

Traditional Chinese medicine enema for acute chronic liver failure: A protocol of systematic review and meta-analysis of randomized clinical trials.

Background: Acute chronic liver failure (ACLF) is the most common type of liver failure. The clinical symptoms are complex and changeable, the treatment is difficult and the fatality rate is high. It has become an urgent problem to actively seek effective treatment means and improve the clinical efficacy of ACLF patients.

A single-valent long-acting human CD47 antagonist enhances antibody directed phagocytic activities.

Many cancer cells express CD47 as a 'don't eat me' signal to mask their presences from immune recognition and destruction. Such a signal is transmitted when CD47 binds to the signal regulatory protein-α (SIRPα) on macrophages to cut the phagocytic reaction. Most recent studies have focused on developing CD47 blocking agents with different affinities and avidities in order to optimize the therapeutic window between efficacy and toxicities involving normal cells expressing CD47.

[Wnt5a modulates vincristine resistance through PI3K/Akt/GSK3β signaling pathway in human ovarian carcinoma SKOV3/VCR cells].

The aim of this study was to investigate the effect of Wnt5a on the vincristine (VCR) resistance in human ovarian carcinoma SKOV3 cells and its possible mechanism. The drug-resistant SKOV3/VCR cells were established by stepwise exposure to VCR, and then the SKOV3/VCR cells were stably transfected with specific shRNA interference plasmid vector targeting for Wnt5a. The mRNA expression level of Wnt5a was measured by RT-PCR.

A chemical genomics screen to discover genes that modulate neural stem cell differentiation.

The authors designed a chemical genomics screen with the aim of understanding genes and pathways that modulate neural stem/precursor cell differentiation. Multipotent mouse neural precursor cells isolated from cortices of embryonic day 12 (E12) embryos were subjected to spontaneous differentiation triggered by growth factor withdrawal. A quantitative whole-well immunofluorescence assay was set up to screen tool compound sets to identify small molecules with potent, dose-dependent, and reproducible effects on increasing neural stem cell differentiation toward neuronal lineage.

Leukemia inhibitory factor inhibits T helper 17 cell differentiation and confers treatment effects of neural progenitor cell therapy in autoimmune disease.

Neural progenitor cell (NPC) therapy is considered a promising treatment modality for multiple sclerosis (MS), potentially acting through neural repair. Here, we showed that intravenous administration of NPCs ameliorated experimental autoimmune encephalomyelitis (EAE) by selectively inhibiting pathogenic T helper 17 (Th17) cell differentiation. Leukemia inhibitory factor (LIF) produced by NPCs was responsible for the observed EAE suppression.

Extensive infiltration of neutrophils in the acute phase of experimental autoimmune encephalomyelitis in C57BL/6 mice.

To determine the possible involvement of neutrophils in the pathogenesis of experimental autoimmune encephalomyelitis (EAE), we examined their infiltration pattern during the course of MOG35-55-induced EAE in the C57BL/6 mice. Using immunohistochemistry and flow cytometry, we found that the number of neutrophils was significantly increased during onset of disease, remained high at the peak stage and dramatically declined thereafter. Moreover, dual labeling provided anatomical evidence of a prominent accumulation of neutrophils in the center and vicinity of lesion areas of demyelination, axonal loss or axonal degeneration at early stages of EAE.

[A review of recent ten-year study on alpha-asarone].

This article is brief review of study on alpha-asarone after 1996. The summary mainly includes the dosage forms, pharmacokinetics, bioavailability, pharmacological effects, toxicology and clinical uses during the past ten years.

Development and pharmacokinetics of nimodipine-loaded liposomes.

In order to improve the water solubility of nimodipine and prolong the time of the drug in the circulation, nimodipine-loaded liposomes with a small size and high entrapment efficiency were prepared by a method that was easy to scale up (the modified ethanol injection method). The nimodipine liposome dispersions were characterized with respect to particle size distribution, zeta potential and entrapment efficiency. Liposomal nimodipine and nimodipine solution were intravenously administered to mice as a single dose of 4 mg kg-1.

Transfection of primary chondrocytes using chitosan-pEGFP nanoparticles.

Chitosan-pEGFP nanoparticles were synthesized through the complex coacervation of the cationic polymer with pEGFP, in order to examine the potential of chitosan as a non-viral gene delivery vector to transfer exogenous gene into primary chondrocytes for the treatment of joint diseases. The nanoparticles were prepared at an N/P ratio of 3.8 and showed a spherical or irregular shape.

[Influence of seven absorption enhancers on nasal mucosa--assessment of toxicity].

Objective: To study the influence of seven different absorption enhancers on nasal mucosa.

Methods: By testing last time of ciliary movement, velocity of ciliary movement, ciliary structural and specific cellular changes of nasal mucosa the influence of seven different absorption enhancers on nasal mucosa.

Nasal insulin delivery in the chitosan solution: in vitro and in vivo studies.

The effects of chitosan concentrations, osmolarity, medium and absorption enhancers in the chitosan solution on nasal insulin delivery were studied in vitro and in vivo. The penetration of insulin through the mucosa of rabbit nasal septum was investigated by measuring the transmucosal flux in vitro, while the nasal absorption of insulin in vivo was assessed by the efficiency in lowering the blood glucose levels in normal rats. It was demonstrated that increasing concentrations of chitosan up to 1.
