Bestrophinopathies, inherited retinal disorders caused by mutations in the BEST1 gene, illustration. Best disease, autosomal recessive bestrophinopathy and autosomal dominant vitreoretinochoroidopathy
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
