Background: Medical students are more likely to have various physical and psychological issues, but less information is available about the healthcare-seeking behaviour for physical and mental health issues. The aim of this study is to determine the factors affecting medical students' healthcare-seeking when visiting a general practitioner (GP) and/or psychologist.
Methods: 688 medical students (326 International and 362 Hungarian,) participated in a cross-sectional study.
Previously, we showed that after Freund's adjuvant-induced peritonitis, rat mesothelial cells regain their epithelial phenotype through mesenchymal-epithelial transition (MET) accompanied by autophagy. Since bone morphogenetic proteins (BMPs) are well-known MET-inducers, we were interested in the potential expression of BMPs and BMP-induced pathways. Although mesothelial cells expressed lower amounts of BMP7, its level in the peritoneal cavity and mesothelial synthesis of BMP4 were significantly increased during inflammation.

In the case of recommended vaccinations, however, the situation is less favourable, and during the COVID-19 pandemic, anti-vaccination sentiment has also appeared in some groups to a greater extent than before. Reducing this is the task of all health professionals.

IGF1R activation drives the development and malignant progression of colorectal cancer. IGF1R inhibition displays a controversial effect on autophagy.

The interrelated role of HGFR inhibition and TLR9/autophagy signaling in HT29 cancer cells subjected to modified self-DNA treatments has not been clarified. We analyzed this complex interplay with cell metabolism and proliferation measurements, TLR9, HGFR and autophagy inhibitory assays and WES Simple Western blot-based autophagy flux measurements, gene expression analyses, immunocytochemistry, and transmission electron microscopy.

Over the past decade, oncogene-driven carcinogenesis, dysregulated cellular signaling networks, dynamic changes in the tissue microenvironment, epithelial-mesenchymal transitions, protein expression within regulatory pathways, and their part in tumor progression are described in several studies. However, the complexity of metabolic enzyme expression is considerably under evaluated.

We investigated the growth inhibitory mechanism of rapamycin + doxycycline treatment in human breast cancer model systems.

Since the receptor transmits the environmental stimulus, downregulating or upregulating the process on an epigenetic level, the intracellular localization of receptors (signaling organelles: early endosomes or lysosomal degradation: late endosomes) plays a crucial role in the signaling events regulating inflammation and regeneration. Therefore, we focused on the internalization of the receptors as well as the intracellular compartmentalization of signaling molecules during EMT and MET.

During Freund's adjuvant induced inflammation rat mesenteric mesothelial cells transdifferentiate into mesenchymal cell. They express macrophage markers, inflammatory cytokines (TGF-β, TNFα, IL-6), and specific receptors. When primary mesenteric cultures were treated with GM-CSF and/or TGF-β (in vitro), similar phenotypic and biological changes were induced.

Methods: Sprague Dawley rat mesenteric mesothelial cells were used as a model. 1 ml Freund adjuvant was injected into the peritoneal cavity of rat and GM-CSF treatment was used to induce inflammation.
Unlabelled: Inrtoduction: Caveolae are flask shaped with 50-100 nm size, non-clathrin associated invaginations of the plasmamembrane. The main membrane protein of the structures is caveolin-1. Caveolae play an important role in numerous cellular functions including vesicular transport and cell-cycle regulation, and create platforms for classical and alternative signaling pathways.

In this paper, we provide additional evidences about this transition by following the phagocytic activity and the TNFα production of mesenteric mesothelial cells during inflammation. Upon injection of India ink particles or fluorescent-labeled bioparticles (pHrodo) into the peritoneal cavity of rats pretreated with Freund's adjuvant, we found that mesothelial cells efficiently engulfed these particles.

This process was characterized by a dramatic increase of the number of cell organelles and volume of mesothelial cells. After the inflammation reached its maximum, the mesenchymal-like cells gradually regained their epithelial phenotype (mesenchymal-epithelial transition, MET).

Patients And Methods: Between 1993 and 2013, 740 patients (10,303person-years) were treated at our Outpatients' Clinic, of which 121 died. The causes of death were established from the pathological records or the medical certificates of the cause of death.
Objective And Design: During peritonitis, mesothelial cells assume macrophage characteristics, expressing macrophage markers, indicating that they might differentiate into macrophage-like cells.
Materials And Subjects: Twenty-five male rats were used for in vivo experiments. For in vitro experiments, a primary mesentery culture model was developed.
The roles of chemokine receptor V (CCR5) and its polymorphism, rs333 in multiple sclerosis (MS) are controversial. We investigated the receptor and its deletion in a large MS (428) and a numerous control (831) population in Csongrád County (Hungary) and North-Bácska (Serbia). Taqman probes firstly were used for the allele discrimination.
