PURPOSE To examine histological and histomorphometric techniques for measuring collagen in skeletal muscle. METHODS The following staining methods were used in the study: hematoxylin and eosin, Masson's trichrome, reticulin, and picrosirius red, and immunostaining for collagen types I, II, III, IV, and V. Histomorphometric measurements were performed using Corel PhotoPaint and UTHSCSA Image T...

background: microsporidia are known to infect a wide variety of animals including mosquitoes (diptera: cu­licidae). in a recent study on the mosquito fauna of chahar mahal and bakhtiari province, at the central western part of iran, a few larvae of anopheles superpictus were infected with a microsporidium-resembled microorganism. cur­rent investigation deals with the identification of the respo...

This report describes the histopathological features of an ossifying epulis, measuring 1.5 × 1 × 1 cm in length, width and height, respectively, on the lingual surface of the lower jaw of a 2.5 year-old parrot cichlid (Hoplarchus psittacus) from a commercial aquarium. The tumor had appeared in the oral cavity three months prior to its introduction to the laboratory for diagnosis. Grossly, the n...

A retrospective study covering a 12-year period was performed to determine the contribution of the direct wet mount microscopic examination to the identification of intestinal parasites in preserved fecal material. It was determined that each of 898 specimens contained at least one parasite when processed by the direct wet mount, concentration, and trichrome staining procedures. Of these proced...

We studied the origin of extensor carpi radialis brevis using 40 fresh frozen human cadaver specimens. Ten were stained with haematoxylin and eosin and trichrome which showed the collagenous structure of the extensor tendons at their origin. Gross anatomical observation showed that there was no definitive separation between brevis and communis at the osseotendinous junction. The histological fi...

Based on a bibliographic review, the article identifies and offers a critical analysis of scientific production by the public health field in Brazil on genetically modified organisms and food (in)security. Of the 716 articles found on the portals of the Scientific Electronic Library Online (SciELO) and the Coordinating Agency for the Development of Higher Education (Capes), only 8 address the f...

conclusions the results of the study showed a high prevalence of giardia lamblia and blastocystis hominis in rural areas compared to urban regions. therefore it is necessary to promote the public health awareness in the rural population, in order to reduce the frequency of parasitic infections. background nowadays, parasitic infections are a major health problem throughout the world, particular...
