Descrição geral

Thermochemical conversion of methanol to C2-C10 hydrocarbons in the presence of shape-selective zeolites has been reported. Its oxidation on Ru-Pt catalyst system by ruthenium ad-atoms has been proposed.

Aplicação

Used as a solvent in:
  • Preparation of self-assembled monolayers (SAMs) of sulfur derivatives with bactericidal terminal fragments on gold surfaces prior to analytical characterization
  • Measurement of soluble absorption spectra of PTFE samples

Excessive mechanical loading or acute trauma to intervertebral discs (IVDs) is thought to contribute to degeneration and pain. However, the exact mechanisms by which mechanical injury initiates and promotes degeneration remain unclear. This study investigates biochemical changes and extracellular matrix

Macrophages populate the steady-state myocardium. Previously, all macrophages were thought to arise from monocytes; however, it emerged that, in several organs, tissue-resident macrophages may self-maintain through local proliferation. Our aim was to study the contribution of monocytes to cardiac-resident macrophages

Increases in plasma B-type natriuretic peptide (BNP) concentrations in those with acutely decompensated heart failure (ADHF) has been mainly attributed to an increase in NPPB gene transcription. Recently, proBNP glycosylation has emerged as a potential regulatory mechanism in the production
