Evaluation of different mathematical models on fitting the in vitro gas production parameters in beef cattle.

In vitro rumen gas production experiment was conducted with 57 kinds of feedstuff, which were categorized into energy feed, protein feed, and roughage, collected within China. Eight mathematical models were employed to describe the kinetics of in vitro rumen gas production. The results found that for energy feeds, protein feeds, and roughages, respectively, Michaelis-Menten (MM) or Logistic-Exponential with lag (LEL), MM, and Mitscherlich (MIT) exhibited the highest or shown no significant difference compared to the highest coefficient of determination (R) (P < 0.

Prenatal PM exposure affects embryonic hematopoietic development through SOX2-regulated gene expression.

Fine particulate matter (PM) is one of the most concerning air pollutants, with emerging evidence indicating that it can negatively impact embryonic development and lead to adverse birth outcomes. Hematopoiesis is a critical process essential for the survival and normal development of the embryo, consisting of three temporally overlapping stages and involving multiple hematopoietic loci, including the yolk sac and fetal liver. Therefore, we hypothesized that abnormal embryonic hematopoietic development can significantly influence developmental outcomes.

PM Exposure Induces Glomerular Hyperfiltration in Mice in a Gender-Dependent Manner.

As one of the most common air pollutants, fine particulate matter (PM) increases the risk of diseases in various systems, including the urinary system. In the present study, we exposed male and female C57BL/6J mice to PM for 8 weeks. Examination of renal function indices, including creatinine (CRE), blood urea nitrogen (BUN), uric acid (UA), and urinary microalbumin, indicated that the kidneys of female mice, not male mice, underwent early renal injury, exhibiting glomerular hyperfiltration.

Phenanthrene perturbs hematopoietic development and causes hematopoietic defects in zebrafish.

Phenanthrene (Phe) is one of the common polycyclic aromatic hydrocarbons in the environment, and recent studies show that it can cause cardiac developmental toxicity and immunotoxicity. However, it is still unknown whether it can affect the hematopoietic development in aquatic organisms. To address this question, zebrafish (Danio rerio) were chronically exposed to Phe at different concentrations.

Immunobiological signatures and the emerging role of SPP1 in predicting tumor heterogeneity, malignancy, and clinical outcomes in stomach adenocarcinoma.

Background: Immunotherapy, as a form of immunobiological therapy, represents a promising approach for enhancing patients' immune responses. This work aims to present innovative ideas and insights for prognostic assessment and clinical treatment of stomach adenocarcinoma (STAD) by leveraging immunobiological signatures.

Methods: We employed weighted gene co-expression network analysis (WGCNA) and unsupervised clustering analysis to identify hub genes.

New insights into triazole fungicide-caused hematopoietic abnormality in zebrafish based on GRα screening developmental toxicity.

Triazole fungicides (TFs) are known to be common environmental contaminants that can be toxic to aquatic animals, but their developmental toxicity is not fully understood. To address this gap, we first used a glucocorticoid receptor α (GRα)-mediated dual luciferase reporter gene system to explore the possible development toxicity of ten TFs and found that flusilazole (FLU) exhibited stronger agonistic activity against GRα. Subsequent transcriptome sequencing showed that FLU exposure affected GRα activation and hematopoiesis associated with a variety of biological processes, including responses to corticosteroid release, embryonic hematopoiesis, erythroid differentiation, and the development of hematopoietic or lymphoid organs.
