Colorectal cancer poses a significant global health challenge, with a considerable proportion arising from colon adenomas. Understanding the molecules involved in the carcinogenesis process is crucial for improving colon cancer diagnosis and prognosis. While research on the role of epiplakin in cancer remains limited compared to other plakin group proteins, comprehending its expression patterns and correlations can offer valuable insights into colon carcinogenesis.

We interviewed faculty members, faculty members of medical education departments, and medical students from both public and private medical schools in Türkiye between October 1 and December 31, 2020. Working in pairs, we analyzed the transcripts of 49 interviews using open qualitative coding methods with satisfactory levels of coefficients of agreement.

Excessive glutamate secretion has been shown to cause excitotoxicity and neurodegenerative disease. Cerebrolysin is a mixture of enzymatically treated peptides derived from pig brain including neurotrophic factors, like brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF), nerve growth factor (NGF), and ciliary neurotrophic factor (CNTF).

Knowing the virulence properties of enterococci is important to understand the complex pathogenic structures. In this study, we aimed to investigate the virulence factors (asa1, hyl, cylA, efa, ebp, ace, esp, gelE, sprE, fsrA, fsrB, fsrC genes, gelatinase activity, hemolysin, hydrogen peroxide and biofilm production) and antibiotic resistance of Enterococcus faecium and Enterococcus faecalis strains isolated from clinical specimens.

The aim of this study was to investigate the clinical, laboratory and computed tomography features of patients with hospitalized COPD exacerbations in which respiratory viruses were detected using a real-time polymerase chain reaction (PCR) technique.
Materials And Methods: This retrospectively planned study included patients hospitalized in the chest diseases clinic due to exacerbation of COPD between November 2018-February 2019.

Background: HCV virus infections are one of the major health problems in the world that can cause cirrhosis and liver cancer at a higher rate than other hepatitis data. The aim of this study was to determine the prevalence of mixed infections with different HCV genotypes in Turkey and also to evaluate the current HCV genotype and sub-type distributions by a multicentered assessment.
Methods: The HCV genotype data of 17,578 hepatitis C patients collected from 23 centers from different geographic regions covering all Turkey were collected.
Streptococcus pyogenes is an important bacterial pathogen that colonizes the throat and skin of human beings and causes a wide variety of diseases ranging from mild infections like pharyngitis, tonsillitis and impetigo to severe invasive infections such streptococcal toxic shock syndrome, septicemia, and necrotizing fasciitis, and produces a wide variety of virulence factors. The aim of this study was to investigate the antibiotic resistance, virulence genes; [pyrogenic exotoxin genes (speA, C, G, H, I, J, K, L, M, smeZ and ssa), deoxyribonuclease genes (sdaB, spd3, sdc ve sdaD), protease genes (speB, spyCEP ve scpA) and inhibitor genes (mac and sic)] of S.pyogenes strains isolated from throat cultures of patients with symptomatic tonsillo-pharyngitis and typing by multiple locus variable number tandem repeat fingerprinting (MLVF) method.

This framework establishes a broader application of coarse-graining idea via describing (i) a coarse-grained residue/node through its heavy atoms as virtual nodes, (ii) an effective B-factor for such a node, directly obtained from the experimental data, and (iii) a node-node interaction by a cumulative distance-dependent force constant. RESPEC improves the level of correlations with B-factors after optimizing the parameters of the model.

We performed multiple 100-ns molecular-dynamics (MD) simulations and elastic network modeling (ENM) on both apo and complex structures to shed light on the still unclear inhibitory mechanism of one such inhibitor, named bt10. Within the time frame of our MD simulations, we observed stabilization of aromatic clusters at the dimer interface and enhancement of intersubunit hydrogen bonds in the presence of bt10, which point to an allosteric effect rather than destabilization of the dimeric structure.
