Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.

Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet), ampicillin (red).

DNA mutation, a mutation is a change in a DNA sequence, mutations can result from DNA copying mistakes made during cell division.

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.

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.

Copper(II) sulfate with molecular structure. Chemical ingredient used in medical and public health issues.

A model of an Enhanceosome protein complex binding to a strand of DNA. This enhanceosome reacts to infection by viruses by accelerating the production of human interferon and triggering the defenses of the immune system.

Tetradecylthioacetic acid molecule. 3D rendering. Atoms are represented as spheres with conventional color coding.

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.

$Antibodies conjugated with drugs at the FC region are designed to attach a drug to the FC region of the antibody. This technology leverages the specificity of antibodies to deliver the drug directly to target cells. As a result, it can enhance the drug's effectiveness and reduce side effects. This approach is particularly promising in cancer treatment and therapies for autoimmune diseases.\n\nThis image was not created by AI.$
