6-Methylpurine (MeP) is a toxic adenine analog used as a bisubstrate inhibitor of enzymes that bind adenosyl moieties and which may become phosphorylated to levels that inhibit RNA and protein synthesis.

In this paper a method of using the "quick, easy, cheap, effective, rugged, and safe" (QuEChERS) extraction and gas chromatography coupled to mass spectrometry detection (GC-MS) was developed for the analysis of five frequently applied pesticides in papaya and avocado.
The nature of the injury and recovery of nitrate uptake (net uptake) from NaCl stress in young barley (Hordeum vulgare L, var CM 72) seedlings was investigated. Nitrate uptake was inhibited rapidly by NaCl, within 1 minute after exposure to
This work investigated impacts of iodide (I-) on the transformation of the widely used phenolic preservative methylparaben (MeP) as well as 11 other phenolic compounds by potassium permanganate (KMnO4). It was found that KMnO4 showed a low reactivity towards MeP

The formation of O6-methyldeoxyguanosine (O6-MedGuo) was determined by an immuno-slot-blot assay in DNA of various tissues of F344 rats exposed to N-methyl-N-nitrosourea (MNU) in the drinking water at 400 ppm for 2 weeks. Although the pyloric region of the glandular

Patients with 2,8-dihydroxyadenine urolithiasis are either completely or partially deficient in adenine phosphoribosyltransferase activities. Patients with partial enzyme deficiencies, all of whom have been found among Japanese, are homozygotes having a unique mutant adenine phosphoribosyltransferase gene (APRT*J) in double dose
