NOBS was developed by Procter & Gamble in 1983 [2] and was first used in American laundry detergents in 1988. [3] 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
2Na 2 CO 3 ∙3H 2 O 2 → 2Na 2 CO 3 + 3H 2 O 2. In a basic wash solution, hydrogen peroxide loses a proton and is converted to the perhydroxyl anion: H 2 O 2 ⇌ H + + HO 2 −. The perhydroxyl anion then attacks the activator, forming a peroxy acid: HO 2 − + RC(O)X → X − + RC(O)O 2 H
Tetraacetylethylenediamine, commonly abbreviated as TAED, is an organic compound with the formula (CH 3 C(O)) 2 NCH 2 CH 2 N(C(O)CH 3) 2. It is a white solid commonly used as a bleach activator in laundry detergents and in the production of paper pulp. TAED is synthesized through the acetylation of ethylenediamine.
68 Ga III is usually obtained from a dedicated mobile radionuclide source, a Gallium-68 generator, in form of a solution in dilute (0.04–0.1 M) hydrochloric acid (frequently and imprecisely referred to as "68 Ga chloride solution in HCl" despite it contains no species with a Ga–Cl bond but [68 Ga(H 2 O) 6] 3+ complex hydrate cations).

By inhibiting PAI-1, it increases activity of the enzymes tissue plasminogen activator and urokinase, which are involved in the blood clotting cascade. It has been researched for conditions such as hepatic steatosis and diabetic nephropathy, and while it has not been developed for medical use, it is widely used in scientific research. [1] [2 ...
Following the Phase 1 trial,larger Phase 2 studies were launched to further investigate the efficacy and safety of NV-5138 as an adjunctive treatment for adults with TRD. [ 9 ] [ 10 ] [ 3 ] These more extensive trials involved a larger number of participants and was structured to provide more comprehensive data on the compound's potential ...
Sirtuin-activating compounds (STAC) are chemical compounds having an effect on sirtuins, a group of enzymes that use NAD+ to remove acetyl groups from proteins. They are caloric restriction mimetic compounds that may be helpful in treating various aging -related diseases.
Activator Appliance is an Orthodontics appliance that was developed by Viggo Andresen in 1908. This was one of the first functional appliances that was developed to correct functional jaw in the early 1900s. Activator appliance became the universal appliance that was used widely throughout Europe in the earlier part of the 20th century. [1]
