The cytokin interleukin 11 (IL-11) plays an important role in autoimmune diseases, fibrotic complications, and solid cancers. Blocking IL-11 can extend lifespan and improve health.
DNA Molecule: a 3D illustration of the double helix structure reflecting the genetic code. This 3D illustration is a visualization of the DNA molecule showing its characteristic double helix structure. The model reflects the major components of DNA such as the nitrogenous bases (adenine, thymine, guanine, and cytosine), sugars, and phosphate groups that together form the genetic code. This illustration can be used for educational purposes, scientific publications or medical advertising to demonstrate the complexity and beauty of the molecule responsible for heredity and the development of life on Earth.

stx2a is a subtype of Shiga toxin-producing E. coli (STEC) linked to Hemolytic Uremic Syndrome (HUS), a severe condition impacting kidney function and blood clotting. STEC poses a significant risk of foodborne illness and can spread within communities including family members.
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.

Intricate bubble texture macro in bright colors for abstract background. Liquid bubbles lit from below with colors injected into the liquid as a design or art abstract.
Characteristics of fungi living in wood as a group, are polyphyletic under the microscope for education.
Macrophotograph of the structure of DNA: The double helical DNA molecule with a detailed view of the nucleotides. Butterfly dna. This macrophotograph is a magnified image of the structure of DNA, allowing us to view the details of the double helix and the nucleotides that make up the genetic code. The background of the image is dark, which highlights the light strands of DNA and creates a contrast that emphasizes the complexity and beauty of the DNA molecule. This image can be used for scientific, educational or medical purposes and to illustrate topics related to genetics, biology and medical research.
