Alveolar Macrophage Interaction With Air Pollution Particulates
(National Institute of Environmental Health Sciences, 1997)
We applied flow cytometric analysis to characterize the in vitro response of alveolar macrophages (AM) to air pollution particulates. Normal hamster AM were incubated with varying concentrations of residual oil fly ash ...
Dual roles for DNA sequence identity and the mismatch repair system in the regulation of mitotic crossing-over in yeast
(Proceedings of the National Academy of Sciences, 1997)
Sequence divergence acts as a potent barrier to homologous recombination; much of this barrier derives from an antirecombination activity exerted by mismatch repair proteins. An inverted repeat assay system with recombination ...
Vaccination against colonizing bacteria with multiple serotypes
(Proceedings of the National Academy of Sciences, 1997)
Conjugate vaccines protect vaccinated individuals against both disease from and nasopharyngeal carriage of Streptococcus pneumoniae and Haemophilus influenzae. Protection is specific to the capsular serotype(s) included ...
Association between endometriosis, dysplastic naevi and history of melanoma in women of reproductive age
(Oxford University Press (OUP), 1997)
Women with melanoma and its precursor lesions, dysplastic naevi, have a higher prevalence of reproductive disorders than women without melanotic lesions. This association appears strongest among young women with dysplastic ...
Plasma malondialdehyde as biomarker for oxidative stress: reference interval and effects of life-style factors.
(American Association for Clinical Chemistry, 1997)
Antioxidative enzyme activities in human erythrocytes.
(American Association for Clinical Chemistry, 1997)
Reliable and standardized methods are necessary to determine the expression of antioxidative enzymes and their role in maintaining health. In addition, the variability of the enzyme activities within the general population ...
Estrogens and breast cancer
(Instituto Nacional de Salud P�blica, 1997)
In this review, we summarize the epidemiologic evidence for the associations of oral contraceptives and postmenopausal hormones with risk of breast cancer. We also describe the biologic plausibility of these relationships. ...
Measurement Error Correction for Logistic Regression Models with an "Alloyed Gold Standard"
(Oxford University Press, 1997)
Recently, some authors have questioned the validity of methods which correct relative risk estimates for measurement error and misclassification when the ''gold standard'' used to obtain information about the measurement ...
Geographic Variation in Breast Cancer Incidence Rates in a Cohort of U.S. Women
(Oxford University Press, 1997)
Background: Breast cancer mortality and incidence rates vary by geographic region in the United States, Previous analytic studies have measured mortality, not incidence, and have used regional prevalences to control for ...
