Promucetin, a new C-type lectin-like protein modulates coagulation by activating platelets via GPIb.

Background: Snake venom C-type lectin-like proteins (also known as snaclecs) have anticoagulation and procoagulation effects by targeting platelet or coagulation factor IX/X, suggesting their potential as candidates for new anticoagulant drugs. Therefore, this study aims to evaluate the antiplatelet and antithrombotic effects of a new snaclec from venom and its potential as an anticoagulant candidate.

Methods: Promucetin was purified through sequential column chromatography, and its molecular mass was determined by SDS-PAGE.

High-Throughput Determination of Multiclass Chemical Hazards in Poultry Muscles and Eggs Using UPLC-MS/MS.

A high-throughput method for the determination of a variety of chemical hazards in poultry muscle and egg samples was established via ultra-performance liquid chromatography-tandem triple quadrupole mass spectrometry (UPLC-QqQ-MS). The sample preparation procedure was developed based on this quick, easy, cheap, effective, rugged, and safe (QuEChERS) method and validated for 280 chemical hazards potentially present in poultry products. The target compounds in poultry samples were extracted with a 1% formic acid-acetonitrile solution (15:85, /), and the metal ions in the matrix were chelated by adding ethylenediaminetetraacetic acid disodium salt (NaEDTA).

Berberine (BBR) is an active compound in Coptis chinensis, Phellodendron chinense and Radix berberidis, which is clinically used to treat inflammatory bowel disease, but its inhibitory effect on drug-resistant fungi has not been clarified.

Enhanced poly(3-hydroxybutyrate-co-3-hydroxyvalerate) production from volatile fatty acids by Halomonas sp. YJ01 with 2-methylcitrate cycle.

Volatile fatty acids (VFAs) are suitable substrates for synthesizing poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), wherein propionate is a precursor of PHBV biosynthesis; however, high concentrations are toxic to bacteria. Therefore, VFAs with suitable ratio are needed. Here, with the ratio of acetate: propionate: butyrate being 1:4:2, the maximum PHBV content and the 3HV content were 46.

Elective high frequency oscillatory ventilation versus conventional mechanical ventilation on the chronic lung disease or death in preterm infants administered surfactant: a systematic review and meta-analysis.

Background: Use of elective high frequency oscillatory ventilation (HFOV) compared with conventional mechanical ventilation (CMV) results in a small reduction in the risk of chronic lung disease (CLD) or death, but the evidence is weak. Our objective was to explore whether elective HFOV was associated with less CLD or death as compared with CMV in preterm infants administered surfactant.

Methods: We conducted a systematic review and meta-analysis, including 1835 ventilated participants from 11 randomized controlled trials comparing elective HFOV with CMV between February 1993 and February 2014.

Targeted volatile fatty acid production based on lactate platform in mixed culture fermentation: Insights into carbon conversion and microbial metabolic traits.

In this study, the effects of fermentation pH and redox potential on the performance of the lactate platform were comprehensively evaluated. The results indicated that the type of acidogenic fermentation was influenced by redox potential, while pH was correlated with volatile fatty acid yield. The highest propionate yield was achieved under anaerobic conditions at a pH of9, with the dominant genus Serpentinicella producing propionate through the acrylate pathway.

A novel snake venom C-type lectin-like protein modulates blood coagulation by targeting von Willebrand factor and coagulation factor IX.

Unraveling the causal links and novel molecular classification of Crohn's disease in breast Cancer: a two-sample mendelian randomization and transcriptome analysis with prognostic modeling.

Background: Crohn's disease (CD), a prominent manifestation of chronic gastrointestinal inflammation, and breast cancer (BC), seemingly disparate in the medical domain, exhibit a shared characteristic. This convergence arises from their involvement in chronic inflammation and immune responses, an aspect that has progressively captivated the attention of investigators but remain controversial.

Methods: We used two-sample Mendelian Randomization (MR) and transcriptomics to explore the relationship between CD and BC.

Dimethyloxallyl Glycine Preconditioning Promotes the Anti-inflammatory and Anti-fibrotic Effects of Human Umbilical Cord Mesenchymal Stem Cells on Kidney Damage in Systemic Lupus Erythematosus Related to TGF-β/Smad Signaling Pathway.

Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease lacking effective treatments without adverse effects. Dimethyloxallyl glycine (DMOG) enhanced mesenchymal stem cells (MSC) capabilities, but it remains unclear how DMOG-pretreatment of MSCs augments their SLE treatment. Here, we explore the therapeutic potential of DMOG-pretreated human umbilical cord MSCs (hUC-MSCs) in a mouse lupus nephritis (LN) model.
