Of rodents and humans: a light microscopic and ultrastructural study on cardiomyocytes in pulmonary veins
Cardiomyocytes in pulmonary veins (PVs) have been reported in rodents and humans. In humans they were related to atrial arrhythmias, including atrial fibrillation (AF). To investigate histological similarities and differences in PV cardiomyocyte localization and distribution, we performed comparative light and electron microscopic studies on humans, rats and mice, and generated a transgenic mou...
متن کاملOcular toxicity of desferrioxamine: light microscopic histochemical and ultrastructural findings.
This study documents for the first time light and electron microscopical changes in the retinal pigment epithelium (RPE) following treatment with high dose desferrioxamine for systemic iron overload. The changes include loss of microvilli from the apical surface, patchy depigmentation, vacuolation of the cytoplasm, swelling and calcification of mitochondria, and disorganisation of the plasma me...
متن کاملA light and electron microscopic study
The corneal stromal lesions of a case of lattice dystrophy that fulfilled all the clinical and histopathologic criteria of this disease were examined by light and electron microscopy. The lesions were found to consist of two distinct parts: (1) a nonbirefringent mass of disoriented filaments of approximately one-third the diameter of normal stronml collagen fibrils and (2) a second, birefringen...
متن کاملCanine malignant melanotic schwannomas: a light and electron microscopic study of two cases.
Malignant, melanotic schwannoma of the spinal cord was diagnosed in two two-year-old dogs. The neoplastic spindle cells were arranged in a herringbone or storiform pattern; the intracytoplasmic melanin varied in amount in different areas of the two neoplasms. Ultrastructural features including cytoplasmic lamellar premelanosomes and melanosomes, rudimentary cell junctions, scattered pinocytotic...
متن کاملA microscopic description and ultrastructural characterization
1 2 Dientamoeba fragilis is a pathogenic trichomonad found in the gastrointestinal tract of 3 humans and is implicated as a cause of diarrhoea. Despite its discovery over a century 4 ago, there has been no recent thorough description of this parasite by microscopy. 5 SEM, TEM, confocal and light microscopy were therefore used to characterize D. fragilis 6 populations growing in xenic culture. T...
