Chronic kidney disease (CKD) is a type of kidney disease in which a gradual loss of kidney function occurs over a period of months to years. Initially generally no symptoms are seen, but later symptoms may include leg swelling, feeling tired, vomiting, loss of appetite, and confusion.
Bilayer Lipid Membrane - 3d rendered image of Cell Membrane Phospholipid Structure, Phospholipid bilayer of the cell membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
Pathogen yeasts infections are treated with fluconazole, that blocks the lanosterol 14-alpha demethylase. This enzyme is essential for the biosynthesis of ergosterol, that is essential for the permeability and rigidity of the fungal plasma membrane. The magnification shows the active site with fluconazole interacting with a heme group. Source PDB entry 5esf.

Prostate cancer is the uncontrolled growth of cells in the prostate, a gland in the male reproductive system below the bladder. Abnormal growth of prostate tissue is usually detected through screening tests, typically blood tests that check for prostate-specific antigen (PSA) levels. Those with high levels of PSA in their blood are at increased risk for developing prostate cancer.
