RESEARCH PROGRESS ON THE ROLE OF GUT MICROBIOTA AND ITS METABOLITES IN THE OCCURRENCE AND DEVELOPMENT OF SEPTIC-ASSOCIATED LIVER INJURY.

Sepsis is a life-threatening organ dysfunction that occurs due to a dysregulated host response to infection. Septic-associated liver injury (SALI) has been closely linked to the prognosis and mortality of sepsis. Recent investigations have delved into the gut-liver axis and its association with SALI, identifying its pivotal role in the gut microbiota.

Neurotoxicity of Tris (1,3-dichloroisopropyl) phosphate in Caenorhabditis elegans.

As a new type of flame retardant, Organic Phosphate Flame Retardant has been widely used worldwide. The purpose of our research is to determine the neurotoxicity of Tris (1,3-dichloroisopropyl) phosphate (TDCPP) to Caenorhabditis elegans and its mechanism. L1 larvae wild-type C.

Preclinical pharmacology and toxicology evaluation of an anti-CD52 monoclonal antibody produced by perfusion fermentation process.

Anti-cluster of differentiation 52 (CD52) monoclonal antibody (mAb) has been employed in the treatment of chronic lymphoblastic leukemia and multiple sclerosis. Previously we developed a perfusion process to produce the biosimilar mAb named "Mab-TH." A series of quality assessments was conducted in the fields of structural identification, purity analysis, and activity measurement.

Efficacy of opioid receptor modulators in patients with irritable bowel syndrome: A systematic review and meta-analysis.

Background: While irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal diseases in clinical practice, it has diverse pathogenesis. Because of its sudden and lingering intractable symptoms, it seriously affects patients work and life. Opioid receptors are G protein-coupled receptors distributed across the brain, spinal cord, skin, and gastrointestinal tract, and each of the subtypes has a unique role and specific distribution.

Long noncoding RNA NORAD regulates MPP+-induced Parkinson's disease model cells.

Background: Long non-coding RNAs (lncRNAs) have been demonstrated to play important roles in human diseases. Yet, the functions of lncRNAs in neurodegenerative disorders, such as Parkinson's disease (PD) are poorly understood. In this study, we used human neuroblastoma SH-SY5Y cell line as a cell-basedin vitro PD model, and investigated the role of lncRNA, Non-Coding RNA Activated By DNA Damage (NORAD) in 1-methyl-4-phenylpyridinium (MPP+)-induced PD-like cytotoxicity.

The effect of hyperosmolality application time on production, quality, and biopotency of monoclonal antibodies produced in CHO cell fed-batch and perfusion cultures.

Hyperosmolality has been commonly investigated due to its effects on the production and quality characteristics of monoclonal antibodies (mAbs) produced in CHO cell fed-batch cultures. However, the application of hyperosmolality at different times and its effect on biopotency have seldom been researched, especially in perfusion culture. In our study, different degrees of hyperosmolality induced by sodium chloride were investigated in anti-IgE rCHO cell fed-batch cultures and anti-CD52 rCHO cell perfusion cultures during the initial and stable phases.

Improved osteogenic differentiation of human dental pulp stem cells in a layer-by-layer-modified gelatin scaffold.

Dental pulp stem cell is a new type of mesenchymal stem cell that has a potential for tissue regeneration. Gelatin sponges are often used for hemostasis in dental surgery. In this study, we aimed to evaluate the dental pulp stem cells' proliferation and osteogenic differentiation in different layer-by-layer-modified gelatin sponge scaffolds including the G, G + P (gelatin sponge+ poly-l-lysine modification), G + M (gelatin sponge + mineralization modification), and G + M + P (gelatin sponge + mineralization modification + poly-l-lysine modification) groups in vitro and assessed them in vivo.

Activation of resin with controllable ligand density via catalytic oxa-Michael addition and application in antibody purification.

This article reported a new strategy for resin activation with divinyl sulfone using catalytic oxa-Michael addition in a controllable manner. By screening a variety of organocatalysts, PPh and DMAP stand out with high catalytic efficiency in aprotic solutions. X-ray photoelectron spectroscopy (XPS) analysis indicates high reaction efficiency and less side reactions than traditional aqueous reactions, resulting in high activation density.

Combination of temperature shift and hydrolysate addition regulates anti-IgE monoclonal antibody charge heterogeneity in Chinese hamster ovary cell fed-batch culture.

Charge heterogeneity has been broadly studied as a critical quality attribute during monoclonal antibody (mAb) production that may subsequently affect product stability and biopotency. However, the charge variation distribution is poorly controlled, so methods of more effective control need to be explored. In this study, the combined effects of temperature shift (37-34, 37-32, or 37-30 °C) and hydrolysate addition (0.
