“Aim: Evidence of relationships between lipid peroxidation and the incidence of coronary heart disease is limited. We therefore investigated this association in a Japanese general population.\n\nMethods: We prospectively studied 1945 individuals who were apparently healthy at the baseline. Cox proportional-hazards models were used to investigate the relationship between serum levels of thiobarbituric acid-reactive substances
(TBARS) as a marker of lipid peroxidation and the incidence of coronary heart disease, adjusted for established risk selleck chemicals factors including age, sex, current smoking, body mass index, systolic blood pressure, glycohemoglobin A1c, serum total cholesterol, and serum high-density lipoprotein cholesterol levels.\n\nResults: During 20,226 person-years of follow-up (median buy GSK1210151A follow-up, 10.9 years), 44 coronary events were documented. The risk of coronary heart disease increased in consecutive tertiles of the TBARS level. On age-and sex-adjusted analysis, the level of TBARS was significantly associated with the incidence of coronary heart disease. The hazard ratio in the highest tertile compared with the lowest tertile was 3.22 (95% confidence interval, 1.38 to 7.53; p = 0.007). On multivariate analysis adjusted for age, sex, and other established risk factors, this association remained significant (hazard ratio, 3.23; 95% confidence interval, 1.28 to 8.16; p = 0.01).\n\nConclusions:
Serum levels of TBARS are a strong and independent predictor of coronary heart disease. selleckchem These findings support the hypothesis that lipid peroxidation is an important risk factor for coronary heart disease.”
“The traditional diet of the Chamorro people of Guam has high
concentrations of the neurotoxin BMAA, beta-methylamino-L-alanine, in cycad tortillas and from animals that feed on cycad seeds. We measured BMAA concentration in washed cycad flour and compared different extraction methods used by previous researchers in order to determine how much BMAA may have been unaccounted for in prior research. Samples were analyzed with AQC precolumn derivatization using HPLC-FD detection and verified with UPLC-UV, UPLC-MS, and triple quadrupole LC/MS/MS. Although previous workers had studied only the free amino acid component of BMAA in washed cycad flour, we detected significant levels of protein-associated BMAA in washed cycad flour. These data support a link between ALS/PDC and exposure to BMAA.”
“The dynamics of bacterial and fungal communities possessing arylsulfatase CARS) activity were followed in the rhizosphere of field-grown rape from stem elongation to seed maturity. Soil ARS activity as well as density, structure and diversity of both cultivable ARS bacterial CARS-BC) and fungal (ARS-FC) communities were determined. ARS activities evolved along the phenology of rape and were correlated at reproductive stages with the densities of ARS-BC and ARS-FC communities.
