In addition to the inherent interest stemming from their ecological and human health impacts, microbes have many advantages as model organisms, including ease of growth and manipulation and relatively simple genomes. However, the imaging of bacteria via light microscopy has been limited by their small sizes. Recent advances in fluorescence microscopy that allow imaging of structures at extremel...

Fluorescence light microscopy (LM) has many advantages for the study of cell organization. Specimen preparation is easy and relatively inexpensive, and the use of appropriate tags gives scientists the ability to visualize specific proteins of interest. LM is, however, limited in resolution, so when one is interested in ultrastructure, one must turn to electron microscopy (EM), even though this ...

background: morphological examinations of urinary erythrocytes can be of diagnostic value in initial evaluation of hematuria. dysmorphic urinary red blood cells are known to indicate a glomerular origin of bleeding. we examined the clinical usefulness of this test in a population complained of hematuria by use of three different methods: light microscopy, phase contrast microscopy, and wright s...

this study was aimed at investigating the photocatalytic degradation of ciprofloxacin (cip) antibiotic in aqueous solution using immobilized zno nanoparticles on glass plate. x-ray diffraction, atomic force microscopy, and scanning electron microscopy were applied to characterize the nanoparticles. to do so, the zno nanoparticles were synthesized through the chemical precipitation method and we...

background: leucocytozoonosis is a disease of birds caused by obligate intracellular protozoa of the genus leucocytozoon. we determined the prevalence of leucocytozoon spp. using light and transmis-sion electron microscopy in domestic birds in southwest of iran. methods: a total of 825 blood smears from 275 birds were examined for presence of infection. the structure morphology of leucocytozoon...
