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.
Biological protein and molecule, 3d rendering. 3D illustration.
Slice of natural crystal for patterns and textures use with high resolution.
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.

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.
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.
Gamma secretase protein complex. Multi-subunit intramembrane protease that plays role in processing of proteins. 3D illustration.
Models of an antibody broadly antagonistic to HIV. A challenge in AIDS and HIV research is producing a vaccine which elicits antibodies effective against the many variations of HIV proteins.Isolated on white.

DNA A-T Pair
The Raf/MEK/ERK (MAPK) propagates growth signals in the cell. Misregulation can lead to cancer.\nThe red dots on the active EGFR are phosphorylated tyrosines. PDB entries: 1egf, 1nql, 1m17, 2jwa, 3njp, 2gs6, 1gri, 1xd2, 3ksy, 5p21, 6xi7, 6q0j, 2y4i,
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.

Nucleosome structure. Structure of an oligonucleosome, showing the packaging of DNA in chromosomes. 3D illustration.
Chain or ribbon diatom, a type of algae.
The glucagon like peptide-1 receptor (GLPr) is a G proteincoupled receptor (GPCR) that mediates the action of GLP-1, a peptide hormone. The activated receptor has a strong effect on the management of type 2 diabetes mellitus and obesity, including glucose homeostasis and regulation of gastric motility and food intake.
Molecular Model of Human Insulin with disulfide bonds shown.

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
