Descripción general

Sodium hydroxide, also known as lye and caustic soda, is a strong base used universally as a neutralization agent in the chemical industry, paper making, petroleum refining, cleaning compounds, and drain cleaners.

Aplicación

Sodium hydroxide can be used as:
  • A reagent in the gold-catalyzed selective oxidation of glycerol to glyceric acid.
  • A catalyst for the cross-dehydrogenative coupling of alcohols and hydrosilanes to synthesize silyl ethers.
  • A base in the Sonogashira-type coupling of aryl halides and alkynes to synthesize ynones.

Polyphosphate (polyP) is secreted by activated platelets and has been shown to contribute to thrombosis, suggesting that it could be a novel antithrombotic target. Previously reported polyP inhibitors based on polycationic substances, such as polyethylenimine, polyamidoamine dendrimers, and polymyxin B

Group 3 innate lymphoid cells (ILC3s) have emerged as important cellular players in tissue repair and innate immunity. Whether these cells meaningfully regulate adaptive immune responses upon activation has yet to be explored. Here we show that upon IL-1β stimulation

There is still considerable debate regarding the actual mechanism by which a "cellulase mixture" deconstructs cellulosic materials, with accessibility to the substrate at the microscopic level being one of the major restrictions that limits fast, complete cellulose hydrolysis. In the

A key step in the process of metastasis is the epithelial-to-mesenchymal transition (EMT). We hypothesized that epigenetic mechanisms play a key role in EMT and to test this hypothesis we analyzed global and gene-specific changes in DNA methylation during TGF-β-induced

Clozapine is effective in the treatment of schizophrenia; however, its use is limited by a relatively high incidence of idiosyncratic agranulocytosis. The mechanism of clozapine-induced idiosyncratic agranulocytosis is unknown. Although most patients treated with clozapine do not develop agranulocytosis, most
