Myelin is a dielectric (electrically insulating) material that forms a layer, the myelin sheath, usually around only the axon of a neuron. It is essential for the proper functioning of the nervous ...
Stem-loops occur in pre-microRNA structures and most famously in transfer RNA, which contain three true stem-loops and one stem that meet in a cloverleaf pattern. The anticodon that recognizes a co...
Alveolar rhabdomyosarcoma is a type of rhabdomyosarcoma characterized by its appearance, which is similar to the alveoli of the lungs. It can be associated with a fusion protein between PAX3 and...

A macrocycle is, as defined by IUPAC, "a cyclic macromolecule or a macromolecular cyclic portion of a molecule."[1] In the chemical literature, organic chemists may consider any molecule containing...
When released into the cell membrane, newly synthesized integrin dimers are speculated to be found in the same "bent" conformation revealed by the structural studies described above. One school of ...
Sulfonamide or sulphonamide is the basis of several groups of drugs. The original antibacterial sulfonamides (sometimes called sulfa drugs or sulpha drugs) are synthetic antimicrobial agents that c...
The compound was reported in 1926 by the chemists Alfred Stock and Erich Pohland by a reaction of diborane with ammonia.[2] Borazine is synthesized from diborane and ammonia in a 1:2 ratio at 25...
A genomic library is a collection of the total genomic DNA from a single organism. The DNA is stored in a population of identical vectors, each containing a different insert of DNA. In order to con...
Polythiophenes (PTs) are polymerized thiophenes, a sulfur heterocycle. They can become conducting when electrons are added or removed from the conjugated π-orbitals via doping.
Gene therapy is the use of DNA as a drug to treat disease by delivering therapeutic DNA into a patient's cells. The most common form of gene therapy involves using DNA that encodes a functional, th...
In humans (as in all other mammals, except for monotremes), implantation is the very early stage of pregnancy at which the conceptus adheres to the wall of the uterus.[1] At this stage of prenatal ...
A plasminogen activator is a serine protease which converts plasminogen to plasmin, thus promoting fibrinolysis. Types include: Tissue plasminogen activator Urokinase It is inhibited by pla...
