A beam splitter is an optical device that splits a beam of light in two. It is the crucial part of most interferometers.
The emergence of resistance of bacteria to antibiotics is a common phenomenon. Emergence of resistance often reflects evolutionary processes that take place during antibiotic therapy. The antibioti...
Certain variations of the BRCA1 gene lead to an increased risk for breast cancer as part of a hereditary breast-ovarian cancer syndrome. Researchers have identified hundreds of mutations in the BRC...
Antiandrogens, or androgen blockers, first discovered in the 1960s, prevent androgens from expressing their biological effects on responsive tissues.[1] Antiandrogens alter the androgen pathway by ...
Selenocysteine (abbreviated as Sec or U, in older publications also as Se-Cys)[2] is the 21st proteinogenic amino acid. It exists naturally in all kingdoms of life as a building block of selenoprot...

A cancer vaccine is a vaccine that either treats existing cancer or prevents development of a cancer. Vaccines that treat existing cancer are known as therapeutic cancer vaccines. There are current...
Methods of hydrogen storage for subsequent use span many approaches, including high pressures, cryogenics, and chemical compounds that reversibly release H2 upon heating. Underground hydrogen stora...

Reticulon 4 receptor (RTN4R) also known as Nogo-66 Receptor (NgR) is a protein which in humans is encoded by the RTN4R gene.[1] This gene encodes the receptor for reticulon 4, oligodendrocytemyelin...
Cancer Listeni/ˈkænsər/, also known as a malignant tumor or malignant neoplasm, is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the bo...
Neoplasm (from Ancient Greek νέος- neo "new" and πλάσμα plasma "formation, creation") is an abnormal growth of tissue, and when also forming a mass is commonly referred to as a tumor or tumour.[1][...
Inflammation (Latin, inflammatio) is part of the complex biological response of body tissues to harmful stimuli, such as pathogens, damaged cells, or irritants.[1] Inflammation is a protective r...

Forward osmosis is an osmotic process that, like reverse osmosis (RO), uses a semi-permeable membrane to effect separation of water from dissolved solutes. The driving force for this separation is ...
Cell sorting is the ability to separate cells according to their properties. These properties can be described as intracellular (inside the cell) or extracellular (outside the cell). Intracellular ...
Nanosensors are any biological, chemical, or surgical sensory points used to convey information about nanoparticles to the macroscopic world. Their use mainly include various medicinal purposes and...
An oncogene is a gene that has the potential to cause cancer.[1] In tumor cells, they are often mutated or expressed at high levels.[2] Most normal cells will undergo a programmed form of rapid ...
A protease (also called peptidase or proteinase) is any enzyme that performs proteolysis, that is, begins protein catabolism by hydrolysis of the peptide bonds that link amino acids together in a p...
An intracranial aneurysm (also called cerebral or brain aneurysm) is a cerebrovascular disorder in which weakness in the wall of a cerebral artery or vein causes a localized dilation or ballooning ...
