This study was aimed to evaluate levels of neutrophil- (NLR), monocyte- (MLR), eosinophil- (ELR), and basophil-lymphocyte ratio (BLR) and their association with inflammatory markers in systemic autoimmune rheumatic diseases (SARDs). A total of 1139 SARD patients and 170 healthy individuals were enrolled. Clinical and laboratory data were extracted. NLR and MLR were significantly increased, but BLR decreased in most SARD patients (p < 0.05). ELR were significantly decreased in systemic lupus erythematosus (SLE) patients, but increased in those with other SARDs (p < 0...

M. genitalium is a reemerging microorganism, responsible for sexually transmissible infections (STIs), with prevalence which varies depending on the country and population group studied. We report here M. genitalium prevalence among the specimens received for STI diagnosis in our routine microbiological laboratory in the university hospital in Marseille, France. We tested 4 624 samples from 3 793 patients using qPCR for M. genitalium, C. trachomatis, N. gonorrheae, T. pallidum. Of these samples, 528 (13.6%) patients were tested positive for at least one pathogen and 126 (3...

Colonization of methicillin resistant Staphylococccus aureus (MRSA) can occur more commonly in healthy people who live in close together or are in close physical contact with each other. Having knowledge about the molecular characteristics of these strains provides considerable discernment into the epidemiology of this important microorganism. A total of 806 nasal swabs were collected from healthy workers of an automaker company in the southeast of Iran and were analyzed to detect MRSA isolates. Multilocus sequence typing (MLST), spa typing, and detection of staphylococcal cassette chromosome mec (SCCmec) were performed...

Atherosclerosis and its associated coronary artery disease (CAD) represent another chronic low-grade inflammatory disorder. Regulatory B cells (Bregs) possess essential functions in maintaining peripheral tolerance and inhibiting pathogenic inflammation through IL-10. Here, we investigated one subset of Bregs, Tim-1(+) B cell, and its role in atherosclerosis and CAD patients. In healthy individuals, IL-10-producing B cells were predominantly found in the Tim-1(+) B cells. Upon stimulation of the B cell receptor (BCR) and Toll-like receptor 9 (TLR-9) by anti-BCR antibodies and CpG, respectively, the Tim-1(+) B cells could further upregulate IL-10 expression...

Metal wear debris has been shown to activate an aseptic osteolytic process that causes failure in total joint arthroplasty (TJA). This osteolysis is characterized by a proinflammatory, self-propagating immune response involving primarily macrophages, dendritic cells, and activated osteoclasts, as well as T cells and B cells. The human bone morphogenic protein (BMP)-7, on the other hand, was shown to promote osteoblast survival, and reversed the downregulation of anabolic Smad proteins and Runx2 following cobalt injury...

Staphylococcus aureus bloodstream infections (SABSI) are associated with high morbidity and mortality. The Toll-like receptor 2 (TLR2) and Toll-interacting protein (TOLLIP) are important in recognition and regulation of human innate immunity response to S. aureus. Single nucleotide polymorphisms (SNPs) in the TLR2 and TOLLIP encoding genes have been associated with disease, including BSI. The aim of this study was to examine potential associations between a selection of SNPs in the genes encoding TLR2 and TOLLIP, and predisposition, severity, and outcome of SABSI...

NUT carcinomas (NC) are rare and aggressive tumours characterized by chromosomal rearrangements of the gene encoding for nuclear protein of the testis (NUT) located on chromosome 15q14. This article presents a case of a 60-year-old woman diagnosed with NC presenting as a fast growing primary tumour in the right palate. Further evaluation revealed a tumour mass in the lungs and widespread metastases. A review of the literature did not reveal earlier cases presenting in the palate. In order to improve early diagnosis it is suggested to perform immunohistochemical testing for NUT in all poorly differentiated carcinomas without glandular differentiation arising in the chest, and head and neck (Clin Cancer Res, 18, 2012, 5773)...

Telomerase activity is present in most cancers and is tightly regulated by the expression of human telomerase reverse transcriptase (hTERT). Hypermethylation in the promoter region of hTERT contributes to the regulation of hTERT expression. In this study, we investigated the methylation and expression of hTERT in oral squamous cell carcinoma (OSCC), oral leukoplakia, and normal oral mucosa. Furthermore, we investigated the significance of hTERT to the clinicopathological findings of OSCC. 35 OSCC, 50 oral leukoplakia (epithelial dysplasia n = 25, squamous cell hyperplasia n = 25), and 10 normal oral mucosa samples were investigated through methylation-specific PCR...

Fifteen to 50% of fetal deaths remain unexplained after post-mortem examination depending on inclusion criteria and classification systems. Our aim was to examine a selection of unexplained fetal deaths in order to investigate whether any common chromosome aberrations or viral infections were present. Reports from 351 fetal autopsies performed at the Department of Pathology and Medical Genetics at St. Olavs University Hospital from 2001 through 2010 were reviewed. Of these, 105 fetal deaths were classified as unexplained...

Chemokine cysteine-X-cysteine motif ligand 8 (CXCL8) is up-regulated in many malignancies, indicating that CXCL8 takes part in tumor progression. However, the expression and function of CXCL8 in osteosarcoma remained not fully elucidated. In this study, expressions of 12 cytokines and chemokines were measured in the serum from 12 of normal controls (NCs) and 25 of osteosarcoma patients. The human osteosarcoma cell line MG-63 was stimulated by recombinant CXCL8 to further analyze invasion, proliferation, apoptosis, cell cycles, cytokine secretions, and signaling pathways...

Bacterial resistance is a growing phenomenon which led the scientific community to search for new therapeutic targets, such as biofilm. A bacterial biofilm is a surface-associated agglomerate of microorganisms embedded in a self-produced extracellular polymeric matrix made of polysaccharides, nucleic acids, and proteins. Scientific literature offers several reports on a biofilm's role in infections regarding various body districts. The presence of a bacterial biofilm is responsible for poor efficacy of antibiotic therapies along with bacterial infections in ear, nose, and throat (ENT) districts such as the oral cavity, ear, nasal cavities, and nasal sinuses...

Helicobacter pylori and Epstein-Barr virus (EBV) infection, and associated cytokines are involved in gastric carcinogenesis. We investigated the expression of these cytokines and their relationship with clinicopathological characteristics. The study included specimens from 207 patients with gastric adenocarcinoma, 56 with chronic gastritis, 32 with metaplasia, and 30 with low-grade epithelial dysplasia. Tissue microarrays were constructed and immunohistochemical staining for IL-1β, IL-6, IL-10, IL-17, p16, p21, TNF-α, and TNFR1 was performed...

We hereby report the detection of the plasmid borne mcr-1 gene conferring colistin resistance in an extended-spectrum β-lactamase (ESBL) producing Escherichia coli ST10 strain retrieved from seawater at a public beach in Norway. The sample was collected in September 2010 and was investigated by whole-genome sequencing in 2016. This report illustrates that E. coli strains carrying plasmid-mediated colistin resistance genes have also reached areas where this drug is hardly used at all. Surveillance of colistin resistance in environmental, veterinary, and human strains is warranted also in countries where colistin resistance is rare in clinical settings...

Grading of canine mammary carcinomas (CMC) is associated to subjective assessments made by the pathologists. Due to its unbiased nature, stereology can be used to objectively quantify morphological parameters associated with grading and malignancy. However, the use of stereology in CMC has not been fully disclosed. The nuclear numerical density [NV (nuclei, tumor)] is a cellularity-associated parameter that can be estimated by the optical disector. Herein, it was estimated in 44 CMC and its association with clinicopathologic factors - such as tumor size, histological subtype and grade, vascular/lymph node invasion, nuclear pleomorphism, and survival - was evaluated...

DNA hypermethylation has emerged as a molecular biomarker for the evaluation of cancer diagnosis and prognosis. We define a methylation signature of bladder cancer and evaluate whether this profile assesses prognosis of patients. Genome-wide methylation analysis was performed on 70 tumor and 10 normal bladder samples. Hypermethylation status of 1505 CpGs present in the promoter region of 807 genes was studied. Thirty-three genes were significantly hypermethylated in ≥10% of the tumors. Three clusters of patients were characterized by their DNA methylation profile, one at higher risk of dead of disease (p = 0...
