INVESTIGATING METHYL BROMIDE DAMAGE OF 'FUJI' APPLES
Acta Horticulturae, 2003Tasmania’s fruit fly free status has allowed the Tasmanian apple industry access to the lucrative Japanese market after the development of a fumigation protocol for the elimination of codling moth. This protocol was developed over a ten year period and access to the market was obtained in 1999.

Cellular Responses to Methylation Damage
1998The study of DNA methylation damage and the cellular response to methylation damage has contributed significantly to our understanding of cell function. The mutagenicity of DNA methylating agents, such as methyl methane sulfonate (MMS) and 1-methyl-l -nitrosourea (MNU), is widely appreciated, and is useful in creating mutants in bacterial and human ...

Neuroinflammation markers and methyl alcohol induced toxic brain damage
Toxicology Letters, 2018Methyl alcohol intoxication is a global problem with high mortality and long-term visual sequelae and severe brain damage in survivors. The role of neuroinflammation in the mechanisms of methyl alcohol-induced toxic brain damage has not been well studied.

Genetic consequences of tolerance to methylation DNA damage in mammalian cells
Carcinogenesis, 1993We previously characterized a clone of CHO cells, clone B, that displayed tolerance to the cytotoxic effects of N-methylnitrosourea (MNU) and 6-thioguanine (6-TG). To determine whether this phenotype affected the mutagenic response of the cells, MNU-induced mutation to 8-azaadenine resistance (8-AAr) was measured in the parental and clone B cells ...

Damage induced by methyl methanesulfonate (MMS) inChlamydomonas reinhardi
Zeitschrift f�r Vererbungslehre, 1966In order to get information about the mechanism of action of alkylating agents, survival was studied after treatment with methyl methanesulfonate, in an arginine-requiring strain of the unicellular green algaChlamydomonas reinhardi. Methylated cells are susceptible to further degradation if they are allowed to stand at ordinary temperature and are ...

Repair of methyl methane sulfonate-damaged phage by Haemophilus influenzae
Molecular and General Genetics MGG, 1983Seven mutants of Haemophilus influenzae strain Rd (mmsA-) have been isolated that are more sensitive to methyl methane sulfonate (mms) than recombination-deficient (recA-) mutants. The mutations cotransformed about 25% with the strA locus while the five studied clustered tightly; they are all probably allelic.

DNA damaging activity of methyl parathion.
Research communications in chemical pathology and pharmacology, 199114C-methyl parathion was covalently bound to DNA, RNA and proteins of various rat and mouse organs 22 hr after i.p. injection. Covalent binding index (CBI) to liver DNA was low in both species and typical of weak initiators. The labelings of RNA and proteins from different organs of both species was slightly higher than DNA binding. No interaction with

Creep behavior of poly(methyl methacrylate) with growing damage
Materials Science and Engineering: A, 2008A simple optical technique is used to quantify creep crazing damage in a uniaxially stressed transparent glassy polymeric sheet of polymethyl methacrylate (PMMA) at room temperature. The areal craze densities are taken as a measure of the crazing damage. It is shown that the crazing damage increases with nominal applied stress and creep time.

DNA Methylation Damage: Formation, Repair and Biological Consequences
2007DNA methylating agents are powerful mutagens and carcinogens. They are endogenously formed, are present in food, beverages and tobacco smoke and are being used in cancer therapy. Methylating agents attack DNA at 13 sites. The main mutagenic and carcinogenic DNA lesion is O6-methylguanine, whereas both N-methylation lesions and O6-methylguanine ...
