General description

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.

Application

Methanol (MeOH) has been used as an eluent in the HPLC estimation of malondialdehyde in plasma, which is an indicator of oxidative stress.
It may be used in the following studies:
  • Colony forming unit-fibroblast assay of bone marrow mononuclear cells.
  • As solvent for the preparation of extracts of hyphae of Aspergillus for the estimation of gliotoxin by reversed phase-HPLC.
  • Immunofluorescence studies.
  • To compose eluent for the ion-pair reverse-phase HPLC isolation of nucleotides and their decomposition products.

Hypoxia-inducible factor-1 alpha (HIF-1α) is considered a global regulator of cellular metabolism and innate immune cell functions. Intracellular pathogens such as Leishmania have been reported to manipulate host cell metabolism. Herein, we demonstrate that myeloid cells from myeloid-restricted HIF-1α-deficient mice

ATP analogs substituted in the gamma-phosphorus (ATPgammaS, beta, gamma-imido-ATP, and beta,gamma-methylene-ATP) were used to probe the involvement of P2 receptors in the modulation of synaptic transmission in the hippocampus, because their extracellular catabolism was virtually not detected in CA1 slices.
