Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).
Focal nodular hyperplasia (FNH) is a benign liver lesion that is composed of a proliferation of hyperplastic hepatocytes surrounding a central stellate scar. Typically, FNH is a solitary lesion that is more commonly seen in women.
SARS-CoV-2 ORF3a is a putative viral ion channel implicated in autophagy inhibition, inflammasome activation and apoptosis. 3D cartoon and Gaussian surface models, based on PDB 7kjr, white background.
A conceptual image of an abstract network of multi-coloured organic strands arranged in a non regular pattern all connected together in a complex manner. The network is made from smaller multi-coloured squares and polyhedra, in vivid colours against a pastel toned background. Shows background and foreground elements to the structure.
Host cells with spores (mold) are inside wood under the microscope for education.

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.

Biological protein and molecule, 3d rendering. 3D illustration.
Pleomorphic liposarcoma. Site: Neck. Pleomorphic liposarcoma is a rare subtype of fat cell cancer in the body. It is a rare and very malignant type of tumor that usually arises from fat cells and deep soft tissues of the upper and lower extremities (shoulder, arms, legs, and thighs).
Thyroid cancer: Microscopic image of Metastatic papillary carcinoma of thyroid. Reactive change. Lymph node carcinoma.
