Macrophages drive a fibrogenic gene program of periductal fibroblasts in pediatric primary sclerosing cholangitis.

Primary sclerosing cholangitis (PSC) is an autoimmune, cholestatic liver disease characterized by inflammation and fibrosis surrounding bile ducts. The cellular crosstalk driving periductal fibrosis remains poorly defined. This study applied a multi-omics approach integrating MERSCOPE spatial transcriptomics, bulk RNA-seq, and SomaScan proteomics to characterize fibrotic periductal regions and their cell-cell communications.

Bile acids engage the SIPR-STAT3 signaling axis to modulate regulatory T cell responses in fibrosing cholangiopathies.

Background & Aims: Regulatory T cells (Tregs), a subset of CD4 lymphocytes, protect against inflammatory tissue injury. However, it is currently unknown how retention of bile acids (BA) in fibrosing cholangiopathies like biliary atresia or PSC shape hepatic Treg responses.

Methods: To induce sclerosing cholangitis (SC), mice were fed a diet containing 0.

Menstrual pattern and anthropometric characteristics of women with primary and secondary infertility in comparison with age-matched controls.

Background: The incidence of infertility has increased significantly due to lifestyle changes and the presence of diverse environmental stress. Body mass index (BMI) and waist circumference (WC) are two common anthropometric measures of obesity. Factors such as differences in race, sex, and age influence BMI, and recent studies have reported limitations in the use of BMI to determine obesity.

Responses of Escherichia coli and Listeria monocytogenes to ozone treatment on non-host tomato: Efficacy of intervention and evidence of induced acclimation.

Because of the continuous rise of foodborne illnesses caused by the consumption of raw fruits and vegetables, effective post-harvest anti-microbial strategies are necessary. The aim of this study was to evaluate the anti-microbial efficacy of ozone (O3) against two common causes of fresh produce contamination, the Gram-negative Escherichia coli O157:H7 and Gram-positive Listeria monocytogenes, and to relate its effects to potential mechanisms of xenobiosis by transcriptional network modeling. The study on non-host tomato environment correlated the dose × time aspects of xenobiosis by examining the correlation between bacterial survival in terms of log-reduction and defense responses at the level of gene expression.

Xenobiotic Effects of Chlorine Dioxide to O157:H7 on Non-host Tomato Environment Revealed by Transcriptional Network Modeling: Implications to Adaptation and Selection.

serotype O157:H7 is one of the major agents of pathogen outbreaks associated with fresh fruits and vegetables. Gaseous chlorine dioxide (ClO) has been reported to be an effective intervention to eliminate bacterial contamination on fresh produce. Although remarkable positive effects of low doses of ClO have been reported, the genetic regulatory machinery coordinating the mechanisms of xenobiotic effects and the potential bacterial adaptation remained unclear.
