“Objective: To examine the relationship between the use of sun-sensitizing medications and cumulative incidence of age-related cataract.\n\nMethods: Sun exposure was estimated from residential history of adults in the Midwestern community of Beaver Dam, Wisconsin, which permitted calculation

of Wisconsin sun-years at the baseline examination. Medication history was reported at each examination. Cataract presence was determined by standardized lens photographs GW4869 cell line that were taken at each examination and graded according to standard protocols.\n\nResults: No significant effects were noted of Wisconsin sun-year exposure or use of sun-sensitizing medications on the cumulative incidence of any type of age-related cataract when controlling for age and sex. However, an interaction term combining Wisconsin sun-years and use of any sun-sensitizing medication was significant (P=.04) such that risk of cortical cataract is significantly higher for the joint risk group. Further controlling for the presence of diabetes mellitus, history of heavy drinking,

and hat or sunglasses use did not alter the relationships.\n\nConclusions: Data suggest that the use of sun-sensitizing medications CAL-101 cell line interacts with sun exposure to influence the risk of cortical cataract, a common age-related cataract. If confirmed, this finding may have important implications for medication use.”
“Irradiation GSK1210151A with a mercury lamp at 254 nm of a p-H-2 matrix containing CH3I and SO2 at 3.3 K, followed

by annealing of the matrix, produced prominent features at 633.8, 917.5, 1071.1 (1072.2), 1272.5 (1273.0, 1273.6), and 1416.0 cm(-1), attributable to nu(11) (C-S stretching), nu(10) (CH3 wagging), nu(8) (SO2 symmetric stretching), nu(7) (SO2 antisymmetric stretching), and nu(4) (CH2 scissoring) modes of methylsulfonyl radical (CH3SO2), respectively; lines listed in parentheses are weaker lines likely associated with species in a different matrix environment. Further irradiation at 365 nm diminishes these features and produced SO2 and CH3. Additional features at 1150.1 and 1353.1 (1352.7) cm(-1) are tentatively assigned to the SO2 symmetric and antisymmetric stretching modes of ISO2. These assignments are based on comparison of observed vibrational wavenumbers and O-18- and S-34-isotopic shifts with those predicted with the B3P86 method. Our results agree with the previous report of transient IR absorption bands of gaseous CH3SO2 at 1280 and 1076 cm(-1). These results demonstrate that the cage effect of solid p-H-2 is diminished so that CH3 radicals, produced via UV photodissociation of CH3I in situ, might react with SO2 to form CH3SO2 during irradiation and upon annealing. Observation of CH3SO2 but not CH3OSO is consistent with the theoretical predictions that only the former reactions proceed via a barrierless path. (C) 2011 American Institute of Physics.
