Stroke is the leading cause of severe disability and the third leading cause of death, accounting for one of every 15 deaths in the USA. We investigated the association of polymorphisms in the soluble epoxide hydrolase gene (EPHX2) with incident ischemic stroke in African-Americans and Whites. Twelve single nucleotide polymorphisms (SNPs) spanning EPHX2 were genotyped in a case-cohort sample of...
The pattern of preferential DNA repair of UV-induced pyrimidine dimers was studied in repair-deficient Chinese hamster ovary (CHO) cells transfected with the human excision repair gene, ERCC-1. Repair efficiency was measured in the active dihydrofolate reductase (DHFR) gene and in its flanking, non-transcribed sequences in three cell lines: Wild type CHO cells, a UV-sensitive excision deficient...

Colorectal cancer (CRC) screening of the average risk population is only indicated according to age. We aim to elaborate a model to stratify the risk of CRC by incorporating environmental data and single nucleotide polymorphisms (SNP). The MCC-Spain case-control study included 1336 CRC cases and 2744 controls. Subjects were interviewed on lifestyle factors, family and medical history. Twenty-on...
Experimental evidence is increasingly being used to reassess the quality and accuracy of genome annotation. Proteomics data used for this purpose, called proteogenomics, can alleviate many of the problematic areas of genome annotation, e.g. short protein validation and start site assignment. We performed a proteogenomic analysis of 46 genomes spanning eight bacterial and archaeal phyla across t...
Cavia intermedia is a rodent species critically endangered and is found only on a 10 hectare island off the southern Brazilian coast. To identify the ectoparasites of C. intermedia, 27 specimens (14 males and 13 females), representing approximately 65% of the estimated total population, were captured and examined. A total of 1336 chewing lice of two species were collected: Gliricola lindolphoi ...
In a recent study, Straub, Limayem, and Karahanna-Evaristo (1995) found little similarity between self reported measures and computer recorded measures of Information Technology (IT) usage. The between method correlation was assessed as 0.293 and the use of these two sets of measures within a nomological context consisting of perceived usefulness and perceived ease of use from the TAM model (Da...
We extract Transit Timing Variation (TTV) signals for pairs of transiting planet candidates that are near first-order Mean Motion Resonances (MMR), using publicly available Kepler lightcurves (Q0-Q9). We are able to solidly confirm the planetary nature of 12 new pairs because their TTV signals exhibit sinusoidal variations at the expected timescale and with reasonable phases. Applying the analy...
BACKGROUND Complaints about memory are common in older people but their relationship with underlying brain changes is controversial. AIMS To investigate the relationship between subjective memory impairment and previous or subsequent changes in white matter lesions and brain volumes. METHOD In a community cohort study of 1336 people without dementia, 4-year changes in brain magnetic resonan...
BACKGROUND Epidemiological studies have shown weak or inconsistent associations between ambient air pollutants and allergic sensitization. The aim of this study was to evaluate whether regional urban air pollution may partly explain the large variation in the prevalence of allergic sensitization across cities of the European Community Respiratory Health Survey (ECRHS) II. METHODS ECRHS is a c...
