Escherichia coli is the main etiological agent of urinary tract infections. Its virulence factors are important during the initial interaction stage with the host as they enable colonization of urinary tract tissues. The genetic markers evidencing susceptibility to develop recurrent infections have been previously described. Toll-like receptors are critical sensors of microbial attacks, and they are also effectors of the individual's innate defense for elimination of pathogens. The aim of this study was to evaluate the association between functional polymorphisms (896 A>G, 1196 C>T, - 2570 A>G, - 2081 G>A) and susceptibility to develop urinary tract infections as well as E...

Septicaemia is an acute inflammatory reaction in the bloodstream to the presence of pathogen-associated molecular patterns. Whole blood stimulation assays capture endotoxin-induced formation of aggregates between platelets and leucocytes using flow cytometry. We wanted to assess extent of spontaneous aggregate formation in whole blood stimulation assays and compare the effects of endotoxin and heat-killed, clinically relevant, bacterial pathogens on aggregate formation and then on adhesion of aggregates to TNFα-stimulated endothelial cells...

Inflammatory bowel diseases have been recognized as predisposing factors to atherosclerosis and thrombotic events, involving both the venous and the arterial circulatory systems. We report the case of a 70-year-old man who presented with ST elevation myocardial infarction during the active phase of ulcerative colitis (UC). Because of the ongoing hematochezia, after successful revascularization of the culprit vessel, the patient was medicated with Clopidogrel, in place of one of the more powerful new oral P2Y12 inhibitors that currently represent the gold standard therapy...

miRNAs are noncoding RNA that play a critical role as fine regulators of gene expression at the posttranscriptional level within cells in numerous autoimmune diseases. miR-221/222 play a role in cancer by regulating cell proliferation, invasion and apoptosis. However, there have been insufficient studies on their role in rheumatoid arthritis (RA). This work is designed to analyze the miR-221/222 expression patterns in peripheral blood mononuclear cells (PBMCs) of patients with RA in comparison with healthy controls using quantitative RT-PCR, in a group of 30 RA patients and 20 healthy controls...

Dipeptidyl peptidase-4 (DPP-4) inhibitors constitute a novel class of anti-diabetic agents confirmed to improve glycemic control and preserve β-cell function in type 2 diabetes. Three major large-scale studies, EXAMINE, SAVOR-TIMI 53, and TECOS, have confirmed the cardiovascular safety profile of DPP-4 inhibitors. Based on these results, DPP-4 inhibitors have gained widespread use in type 2 diabetes treatment. It is currently unknown, however, whether DPP-4 inhibitors have similar therapeutic efficacy against autoimmune diabetes...

Rheumatoid arthritis (RA) is a chronic inflammatory and systemic disease characterized by endothelial activation. The main objective of this study was to verify the profile of cell adhesion molecules (CAM) in RA patients, and the influence of metabolic syndrome (MetS) and drugs used in the treatment of RA in this profile. A second objective was to propose models of prediction of activity in RA using these biomarkers. A total of 115 healthy individuals and 144 RA patients were enrolled. Disease activity was determined by DAS28 (disease activity score 28) based on erythrocyte sedimentation rate (DAS28-ESR) or C-reactive protein (DAS28-CRP)...

Cancer is a genetic disease characterized by uncontrolled cell growth and metastasis. Cancer can have a number of causes, such the activation of oncogenes, the inactivation of tumor-suppressing genes, mutagenesis provoked by external factors, and epigenetic modifications. The development of diagnostic tools and treatments using a molecular biological approach permits the use of sensitive, low-cost, noninvasive tests for cancer patients. Biomarkers can be used to provide rapid, personalized oncology, in particular the molecular diagnosis of chronic myeloid leukemia, and gastric, colon, and breast cancers...

The etiology of rheumatoid arthritis (RA) is thought to involve dysfunction of the programmed cell death 1/programmed cell death ligand 1 (PD-1/PD-L1) pathway; PD-1 negatively regulates autoimmunity by interacting with its ligand, PD-L1. We therefore investigated PD-1/PD-L1 expression in synovial tissue of patients with RA. We immunohistochemically stained synovial specimens from 51 patients with RA and assessed the association between PD-1/PD-L1 expression and rheumatoid factor (RF), the total count of infiltrating T cells, C-reactive protein (CRP), and Krenn's synovitis score...

Type II mixed cryoglobulinemia without evidence of HCV infection but rather with renal involvement has been occasionally described. The pathogenesis of cryoglobulinemic kidney disease is most likely related to immune complex deposition including cryoglobulins, and cryoaggregation after cold exposure could play a pivotal role in clinical expression of cryoglobulinemia. In these cases, acute kidney injury and proteinuria remain the most frequent clinical expression of a cryoglobulinemic glomerulonephritis. Type II cryoglobulinemia with the laboratory finding of both monoclonal and polyclonal cryoglobulins is the most prevalent bio-humoral pattern among HCV-negative phenotypes with renal involvement, while type III cryoglobulinemia with polyclonal Ig is rare...

Glioblastoma multiforme (GBM) is the most common malignancy in central nervous system. A small subpopulation of GBM cells known as GBM stem-like cells (GSLCs) were supposed to be the most malignant cells among GBM cells as they are resistant to multiple therapies including radiotherapy. In this study, we set up two GSLCs cell lines from the two parental U87 and U251 glioma cell lines, and studied the expression of apoptosis-related genes alteration in GSLCs before and after irradiation. We found that one of the receptors of TNF-related apoptosis-inducing ligand (TRAIL), DR5, was dramatically up-regulated in GSLCs after irradiation (IR)...

Hepatocellular carcinoma (HCC) is still a major killing malignancy in sub-Saharan Africa. Lifelong intoxication with aflatoxin B1 is considered as one of the primary causes of this situation. The role of aflatoxin in HCC from a given population is commonly estimated through the prevalence of R249S mutation of TP53, a hallmark for previous exposure to the mycotoxin. However, the role of AFB1 is barely known in large part of Africa. We conducted a survey on circulating cell-free DNA from 149 patients with HCC and 213 control subjects with and without liver diseases from Cameroon and Central African Republic using droplet digital PCR technique...
