anaplastic thyroid carcinoma with heterologous differentiation (leiomyosarcoma)
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.
Phospholipid bilayer membrane structures that make up living cells and their contents. This is an image of membrane proteins in the membrane.\nThis image, which looks like a plastic model, evokes biology and biochemistry. It can be used as a cover for magazines, textbooks and presentation materials.\nThis image was not created by AI.
Halofantrine is a drug used to treat malaria. Halofantrine's structure contains a substituted phenanthrene, and is related to the antimalarial drugs quinine and lumefantrine. 3d illustration
DNA Helix - 3d rendered image. Genetic research concept. Complex spiral structure illustration. Medical, science, genetic biotechnology, gene cell, chromosome idea. DNA strands on dark background . Science nanotechnology.

Close-up shot of a petri dish for checking an antibiotic in the laboratory.
Acetylcholine receptors in the lipid layer of cell membrane.
The protein responsible for Alzheimer's disease has recently been identified. It has been suggested that plaques formed by amyloid-β sheets may interfere with transmission at neuronal synapses. This image uses images of the plaques and the atrophied brain caused by Alzheimer's disease as a backdrop to illustrate the horror of the disease and the realistic phenomenon in vivo.
3D cartoon and Gaussian surface models, chain id color scheme, PDB 2y73, white background
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
Squalane is a hydrocarbon derived by hydrogenation of squalene. 3d illustration
Photomicrograph of algae, Cosmarium turpinii, a desmid. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
Eggs of helminth and Finding parasites in feces, analyze by microscope in laboratory.
Colorful geometric shapes connected with arrows forming a software diagram.
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).
Close-up shot of a petri dish for checking an antibiotic in the laboratory.
Secreted by Staphylococcus aureus, this toxin binds with the outer membrane, with subsequent oligomerization of the toxin monomers to form water-filled channels. These are responsible for osmotic phenomena, cell depolarization and loss of vital molecules (v.gr. ATP), leading to cell death. 3D cartoon model in two purpendicular projections, chain id color scheme, based on PDB 3anz, white background.
Molecular Model of Vitamin E.
Spirogyra algae (filamentous green algae) under the microscope - optical microscope x400 magnification
Photomicrograph of rotifer, probably Rotaria rotatoria. Rapidly rotating cilia at top of head, internal organs visible. Green circles are algae. Live specimen. Original image at 40X, wet mount, transmitted brightfield illumination. Indistinct image due to motion blur of live specimen and very shallow depth of field of brightfield illumination.
