NOBS is the main bleach activator used in the U.S.A. and Japan. [4] Compared to TAED, which is the predominant bleach activator used in Europe, NOBS is efficient at much lower temperatures. At 20 °C NOBS is 100 times more soluble than TAED in water. [5]
The overall reaction of TAED (1) with 2 equivalents of hydrogen peroxide gives diacetylethylenediamine (2) and 2 equivalents of peracetic acid (3): Only the perhydroxyl anion, and not the hydrogen peroxide molecule, reacts with the bleach activator. [4]
TAED was first used in a commercial laundry detergent in 1978 (Skip by Unilever). [1] Currently, TAED is the main bleach activator used in European laundry detergents and has an estimated annual consumption of 75 kt. [2]
Krueppel-like factor 12 is a protein that in humans is encoded by the KLF12 gene. [5] [6]Activator protein-2 alpha (AP-2 alpha) is a developmentally-regulated transcription factor and important regulator of gene expression during vertebrate development and carcinogenesis.
Activator may refer to: Activator (genetics) , a DNA-binding protein that regulates one or more genes by increasing the rate of transcription Activator (phosphor) , a type of dopant used in phosphors and scintillators
[3] [1] [4] [5] NV-5138 works by binding to and modulating sestrin2, a cellular sensor protein for the amino acid leucine, which is a natural activator of mammalian target of rapamycin complex 1 (mTORC1) signaling pathway.
The tool's design is based on a dental impactor, [6] a device that taps dental amalgam into cavities in teeth. [4] Activator I was patented by Activator Methods International on September 26, 1978. [4] [7] [8] Activator II was released, with an added "impedance head", in 1994. [4]
Alteplase, sold under the brand name Activase among others, is a biosynthetic form of human tissue-type plasminogen activator (t-PA). It is a thrombolytic medication used to treat acute ischemic stroke, acute ST-elevation myocardial infarction (a type of heart attack), pulmonary embolism associated with low blood pressure, and blocked central venous catheter.
