BACKGROUND Schistosome infections are often clinically silent, but some individuals develop severe pathological reactions. In several disease processes, T-helper 17 (Th17) cells have been linked to tissue injuries, while regulatory T cells (Tregs) are thought to downmodulate inflammatory reactions. We assessed whether bladder pathology in human Schistosoma haematobium infection is related to th...

Background: Anogenital wart is a common sexually transmitted disease affecting both genders. The aim of this study was to evaluate human papilloma virus types of anogenital warts with Polymerase Chain Reaction (PCR). Method: 65 formalin fixed paraffin embedded (FFPE) tissue blocks of the anogenital warts obtained from the pathology lab of Loghman Hakim hospital were included in this study. Resu...

Marc Ladanyi, M.D., obtained his medical degree from McGill University (Montre al, Canada) in 1984, where he then began postgraduate training in anatomic pathology. He completed his training in tumour pathology and molecular genetics at Memorial Sloan± Kettering Cancer Center in New York City, where he is now Assistant Attending Pathologist in the Departments of Pathology and Human Genetics, a...

Gastric colonization with Helicobacter pylori induces diverse human pathological conditions, including superficial gastritis, peptic ulcer disease, mucosa-associated lymphoid tissue (MALT) lymphoma, and gastric adenocarcinoma and its precursors. The treatment of these conditions often relies on the eradication of H. pylori, an intervention that is increasingly difficult to achieve and that does...

Transgenic animal models of Aβ pathology provide mechanistic insight into some aspects of Alzheimer disease (AD) pathology related to Aβ accumulation. Quantitative neuroimaging is a possible aid to improve translation of mechanistic findings in transgenic models to human end phenotypes of brain morphology or function. Therefore, we combined MRI-based morphometry, MRS-based NAA-assessment and qu...

Recent findings concerning Drosophila melanogaster intestinal pathology suggest that this model is well suited for the study of intestinal stem cell physiology during aging, stress and infection. Despite the physiological divergence between vertebrates and insects, the modeling of human intestinal diseases is possible in Drosophila because of the high degree of conservation between Drosophila a...

Background and objective: Langerhans cell histiocytosis (LCH) is a rare histiocytic proliferative disorder of unknown etiology and mainly affects young children. The histological feature is granuloma-like proliferation of langerhans-type dendritic cells. Although the possible role of viruses such as Epstein-Barr virus (EBV, Human Herpes virus -4</...
