Nucleosome structure. Structure of an oligonucleosome, showing the packaging of DNA in chromosomes. 3D illustration.
Myxoid liposarcoma.  Myxoid/round cell liposarcoma, or MRCLS, is one of several types of liposarcoma. Liposarcoma is a rare cancer that grows in the cells that store fat in the body. MRCLS usually grows in the arms and legs. These tumors grow slowly, and they can spread to other parts of the body

stx2a is a subtype of Shiga toxin-producing E. coli (STEC) linked to Hemolytic Uremic Syndrome (HUS), a severe condition impacting kidney function and blood clotting. STEC poses a significant risk of foodborne illness and can spread within communities including family members.
After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.

Nanomedicine inside of closed single layer carbon nanotube with conjugated antibodies 3d rendering
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.
Immunotherapy of Alzheimer's disease: Monoclonal antibody (light blue) bound to an amyloid beta peptide (orange),  that is aggregated to amyloid beta fibrils, which build up amyloid plaques.
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.

3D cartoon and Gaussian surface models, PDB 1j7n, chain id color scheme, white background
Candida albicans grown on chromogenic agar plates. Candida albicans, a fungus naturally present in small quantities on the body, inhabits areas such as the mouth, skin, and intestines. When the balance with healthy bacteria is disrupted, Candida can lead to infections like thrush and vaginal yeast infections. These infections are frequent and typically addressed with antifungal medications.
Calreticulin, a protein which binds to misfolded proteins and prevents them from being exported from the endoplasmic reticulum to the Golgi apparatus. 3d rendering.
