Catalysis is the increase in the rate of a chemical reaction by the addition of a reagent — the catalyst — that is not itself consumed. The catalyst works by opening up a route between starting material and product with a lower activat ...
A homogeneous catalyst is one whose molecules are dispersed in the same phase (usually gaseous or liquid) as the reactant's molecules. A heterogeneous catalyst is one whose molecules are not in the same phase as the reactants, which are typica ...
Catalysis (/kəˈtælÉ™sɪs/) is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (/ˈkætÉ™lɪst/), which is not consumed in the catalyzed reaction and can contin ...
Membranous nephropathy (MEM-bruh-nus nuh-FROP-uh-thee) occurs when the small blood vessels in the kidney (glomeruli), which filter wastes from the blood, become damaged and thickened. As a result, proteins leak from the damaged blood vessels ...
A hydrogel is a network of polymer chains that are hydrophilic, sometimes found as a colloidal gel in which water is the dispersion medium. A three-dimensional solid results from the hydrophilic polymer chains being held ...
Cyclooxygenase (COX), officially known as prostaglandin-endoperoxide synthase (PTGS), is an enzyme (specifically, a family of isozymes, that is responsible for formation of prostanoids, including thromboxane and prostagl ...
The chemical data analysis defined by the term "chemometrics" means performing calculations on measurements of chemical data. This can be anything from- calculating pH from a measurement of hydrogen ion activit ...
The biochemical processes in the brain exhibit various peculiarities with ramifications in brain injury. First is the presence of a blood brain barrier formed by endothelial cell layers of the brain vessels, which plays ...
Good clinical practice (GCP) is an international quality standard for conducting clinical trials, in some countries, provided by the ICH, an international body which defines a set of standards, which can then be used to ...
A biofilm may also be considered a hydrogel, which is a complex polymer that contains many times its dry weight in water. Biofilms are not just bacterial slime layers but biological systems; the bacteria organize themsel ...
In pharmacology, bioavailability (BA or F) is a subcategory of absorption and is the fraction (%) of an administered drug that reaches the systemic circulation. By definition, when a medication is ad ...
Asthma and allergic diseases are complex conditions caused by a combination of genetic and environmental factors. More than 100 genes have been associated with asthma and related conditions.Allergic asthma has been called a “syndrome” resu ...
Epigallocatechin gallate (EGCG), also known as epigallocatechin-3-gallate, is the ester of epigallocatechin and Gallic acid and is a type of catechin. EGCG – the most abundant catechin in tea – is a polyphenol under basic research for ...
An immobilized enzyme is an enzyme attached to an inert, insoluble material—such as calcium alginate (produced by reacting a mixture of sodium alginate solution and enzyme solution with calcium chloride). This can ...
Fed-batch culture is, in the broadest sense, defined as an operational technique in biotechnological processes where one or more nutrients (substrates) are fed (supplied) to the bioreactor during cultivation and in which the product(s) remain in t ...
Biochip, the most exciting future technology is an outcome of the fields of Computer science, Electronics and Biology. It is a new type of bio -security device to accurately track information and who is actually doing it. Biochips promises to brin ...
Difference gel electrophoresis (DIGE) is a form of gel electrophoresis where up to three different protein samples can be labeled with size-matched, charge-matched spectrally resolvable fluorescent dyes (for example Cy3, Cy5, Cy2) prior to two-dim ...
