BACKGROUND In order to prevent spread of the endemic pathogens bovine coronavirus (BCoV) and bovine respiratory syncytial virus (BRSV) between herds, knowledge of indirect transmission by personnel and fomites is fundamental. The aims of the study were to determine the duration of viral RNA carriage and the infectivity of viral particles on fomites and human nasal mucosa after exposure to BCoV ...
BACKGROUND Epithelial-to-mesenchymal transition (EMT) is a phenomenon that allows the conversion of adherent epithelial cells to a mesenchymal cell phenotype, which enhances migratory capacity and invasiveness. Recent studies have suggested that EMT contributes to the pathogenesis of ulcerative colitis (UC). We investigated the promoter DNA methylation status of EMT-related genes in the colonic...
BACKGROUND Inflammatory bowel disease is a premalignant condition for developing colorectal cancer. Since a correlation has been suggested between telomere length, chromosomal instability and neoplastic transformation in this setting, we sought to investigate whether telomerase expression in colorectal mucosa may constitute a biomarker for malignant transformation in patients with inflammatory ...

Background and Aim: patients infected with HIV are susceptible to opportunistic infections such as candidiasis. In normal individuals, Candida spp. exist as normal flora of the mucous membranes. In this study we compared the frequencies of different species of Candida between HIV infected patients receiving anti-retroviral therapy (ART) and normal individuals. Materials and Methods: This case...
UNLABELLED Mucocutaneous Leishmaniasis (ML) can lead to serious sequela; however, early diagnosis can prevent complications. AIM To evaluate clinical markers for the early diagnosis of ML. MATERIALS AND METHODS A series study of 21 cases of ML, which were evaluated through clinical interview, nasal endoscopy, biopsy and the Montenegro test. RESULTS A skin scar and previous diagnosis of cu...
