Acetylcholine receptors in the lipid layer of cell membrane.
Metastatic melanoma. Site: Neck. Metastatic melanoma is a disease that occurs when the cancerous cells from the original tumor (primary tumor) get loose, spread by traveling through the lymph or blood circulation, and start a new tumor (metastatic tumor) somewhere else.
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).

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.
The study of plant tissues under the microscope in the laboratory.
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.
HER2 (light blue)  locked in the inactive conformation by Trastuzumab (left) and Pertuzumab. Trastuzumab has drastically improved the prognosis of HER2-positive breast cancer patients.
Microscopic photograph of a professionally prepared slide demonstrating vulvar malignant melanoma. Melanomas of the vulva and vagina are rare, accounting for no more that 2% of melanomas among women. Melanoma of the vulva behaves like melanoma in any other location and may affect a much younger population.
Thyroid cancer: Microscopic image of Metastatic papillary carcinoma of thyroid. Reactive change. Lymph node carcinoma.
Shiny artificial molecular structure in many colors. Horizontal composition, isolated on black background.

Computer generated abstract concept image of 3d spheres like metaphor of abstract business processes.
Amitriptyline is used as an antidepressant and antimigraine drug. It blocks sodium channels on neuronal membrans. Sodium channels generate and propagate action potentials in neurons and muscle. Source: PDB entry 6AGF
Rosai–Dorfman disease (RDD) is a rare proliferative histiocytic disorder of unknown etiology. RDD typically presents with generalized lymphadenopathy and polymorphic histiocytic infiltration of the lymph node sinuses; however, occurrences of extranodal soft tissue RDD may rarely occur when masquerading as a soft tissue sarcoma.
