Life-threatening infections are on the rise due to drug-resistant bacteria. Carbapenemase-producing organisms (CPO) are bacteria that have become resistant to a group of antibiotics known as carbapenems. CPO are emerging pathogens world wide.
Epidermis. Electron microscope micrograph showing a keratinocyte of spinous layer. The epithelial cell has a polygonal shape, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous dark desmosomes crossing the intercellular spaces.
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.
Microalgae under microscopic view, green algae, cyanobacteria, phytoplankton, diatom, algae mix collage background
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Epidermal growth factor (EGF) activates the EGF receptor (EGFR), that dimerizes. Red dots are phosphorylated tyrosines. The signal transduction continues through GRB2/SOS, Ras,  Raf/MEK and ERK, that will activate many processes in the cell.
Burkitt lymphoma is a form of non-Hodgkin's lymphoma in which cancer starts in immune cells called B-cells. Recognized as a fast growing human tumor, Burkitt lymphoma is associated with impaired immunity and is rapidly fatal if left untreated.
