INTRODUCTION Microsporidia spp. are ubiquitous and infect a wide variety of intervertebrates and vertebrates, including humans. Pulmonary microsporidiosis, characterized by nonspecific symptoms like fever, cough and dyspnea, is often overlooked in the differential diagnosis of pulmonary infections in immunsupressed patients. In this study, we aimed to determine the prevalence of pulmonary micro...

The aim of this study was to evaluate the value of the direct fluorescent antibody (DFA) techniques reported to have high sensitivity and specificity and the enzyme linked immunosorbent assay (ELISA) test used to determine antigens in stool samples in the routine diagnosis of Giardia intestinalis. When 44 stool samples in which G. intestinalis cysts and/or trophozoites had been seen during nati...

Interstitial fibrosis is an outcome measure of increasing importance in clinical trials of both renal transplantation and native disease, but data on the comparative advantages of fibrosis measurement methods are limited. We compared four morphometric techniques and contrasted these with two visual fibrosis-scoring methods on trichrome-stained slides. Two morphometric methods included whole-sli...

The use of a faecal preservative and several staining methods, together with formalin ether concentration, were evaluated for the improved diagnosis of intestinal amoebiasis and giardiasis in 1285 patients with diarrhoea or dysentery and from asymptomatic controls. All samples were screened by three wet mount techniques. Thirty eight specimens of diarrhoeal or dysenteric stool were preserved in...

Tissue-engineered bone substitutes are frequently used to repair bone defects. Adipose-derived stem cells (ASCs) are a promising source of cells for repairing bone tissue, however, insufficient osteogenic potency remains the main obstacle for their application. The present study aimed to enhance the osteogenic potency of ASCs by transfection of microRNA (miR)‑26a, a novel osteogenic and angioge...

Case presentation: The following case is a description of two-year-old girl whose diagnostic for Mitochondrial Myopathy was considered after presenting two episodes impaired consciousness. At first, she admitted at pediatric emergency with fever, nasal discharge and sleepiness, eight months old. Cerebrospinal Fluid analysis came normal. After short period clinical observation, consciousness imp...

A prospective observational study was conducted to determine the prevalence and the clinical impact of intestinal parasitic infections in diarrheal illness among HIV-infected and HIV-uninfected children hospitalized with diarrhea in Bangkok, Thailand. Stool samples were examined for intestinal parasites using a simple smear method, a formalin-ether concentration method, a modified acid-fast sta...

Previously we found carbon tetrachloride (CCl₄) induced cirrhosis associated cardiac hypertrophy and apoptosis. The purpose of this study is to determine whether further CCl₄ treatment would induce cardiac cell fibrosis. The cardiac tissues were analyzed by H&E. histological staining, Trichrome Masson staining and Western blotting. The results showed that the CCl₄-treated-only group exhibits mo...

OBJECTIVES To assess the efficacy of the Kato-Katz technique and to re-evaluate other routine procedures conducted in the Microbiology Clinical Laboratory at Sultan Qaboos University Hospital (SQUH) and to throw light on the prevalence of intestinal parasitic infections among a small group of food handlers in Muscat. METHOD Faecal samples collected from food handlers were examined using five ...
