The aim of this study is to formulate a new single nonselective pre-enrichment medium (ELSS) that can support the concurrent growth of four major foodborne pathogens containing O157: H7, . , . and . serovar Entertidis to develop a multiplex TaqMan Real-time PCR (mRT-PCR). The mRT-PCR with a new pre-enrichment was carried out for simultaneous detection and quantification of these foodborne bacteria. By using mRT-PCR after 16 h pre-enrichment in ELSS, the detection limit of each pathogen was 1 CFU/25 ml contaminated milk, as well as inclusivity and exclusivity reached 100%. The mRT-PCR assay with pre-enrichment step is a fast and reliable technique for detecting single or multiple pathogens in food products.

Lung cancer progression is characterized by intricate epigenetic changes that impact critical metabolic processes and cell death pathways. In this study, we investigate the role of histone lactylation at the AIM2 locus and its downstream effects on ferroptosis regulation and lung cancer progression. We utilized a combination of biochemical assays, including chromatin immunoprecipitation (ChIP), quantitative real-time PCR (qRT-PCR), and western blotting to assess histone lactylation levels and gene expression.

Esophageal carcinoma is a highly prevalent malignancy worldwide. The present study aimed to investigate the mechanism by which the natural compound coptisine affects pyroptosis in esophageal squamous cell carcinoma (ESCC). The expression of c-Met in ESCC patients was assessed by immunohistochemical analysis of tissue microarrays.

Purpose: Dry eye disease (DED) is a common ocular surface inflammatory disease with a complex pathogenesis. Herein, the role and effect of gasdermin E (GSDME) in DED pathogenesis were explored.
Methods: In vitro, flow cytometry, Cell Counting Kit-8 (CCK-8) and lactate dehydrogenase (LDH) release assays were used to determine the effects of hyperosmotic stress on pyroptosis, apoptosis, and cell viability in human corneal epithelial cells (HCECs).

Copy number variations (CNVs) have become widely acknowledged as a significant source of genomic variability and phenotypic variance. To understand the genetic variants in horses, CNVs from six Indian horse breeds, Manipuri, Zanskari, Bhutia, Spiti, Kathiawari and Marwari were discovered using Axiom Equine Genotyping Array. These breeds differed in agro-climatic adaptation with distinct phenotypic characters.

Background: Paternal preconception alcohol exposure affects fetal development; however, it is largely unknown about the influences on offspring vasculature and mechanisms.
Methods: Offspring born form paternal rats treated with alcohol or water before pregnant was raised until 3 months of age. Vessel tone of mesenteric arteries was detected using myograph system; whole-cell calcium channel current in smooth muscle cells was tested using patch-clamp; molecule expressions were detected with real-time PCR, western blotting, and Dihydroethidium (DHE); DNA methylations were determined using targeted bisulfate sequencing assay.
