Genome-wide and candidate-gene association studies of bladder cancer have identified 10 susceptibility loci thus far. We conducted a meta-analysis of two previously published genome-wide scans (4501 cases and 6076 controls of European background) and followed up the most significant association signals [17 single nucleotide polymorphisms (SNPs) in 10 genomic regions] in 1382 cases and 2201 cont...
BACKGROUND Data on sexually transmitted infections (STIs) in Saudi Arabia (SA) and other Islamic countries are limited. This study describes the results of a five-year surveillance for STIs in SA. METHODS This is a case series descriptive study of all confirmed STIs diagnosed in SA from January, 1995 through December, 1999. RESULTS A total of 39049 STIs were reported to the Ministry of Heal...
OBJECTIVE The aim of this retrospective study was to assess the prevalence and distribution of hypodontia in the permanent dentition in a sample of Turkish patients who referred to the Ankara Dental Hospital for orthodontic treatment. MATERIALS AND METHODS The pre-treatment orthodontic records of 2530 patients, 1382 girls (54.62%) and 1148 boys (45.38%) between the chronological ages of 7 and...
We report a database of circadian genes in eukaryotes (CGDB, http://cgdb.biocuckoo.org), containing ∼73 000 circadian-related genes in 68 animals, 39 plants and 41 fungi. Circadian rhythm is ∼24 h rhythm in behavioral and physiological processes that exists in almost all organisms on the earth. Defects in the circadian system are highly associated with a number of diseases such as cancers. Alth...

With the help and supervision of a facilitator, a scheme of nurse-run health checks was established in 1983 in a suburban group practice of approximately 12 000 patients. The practice receptionists recruited patients opportunistically when they presented to consult a doctor. After two and a half years, 1382 patients had been screened for cardiovascular risk factors; this was 94.0% of those invi...
—With a sample of 94 Pleistocene cranial capacities between the time period of 1.8 Ma and 50 Ka now known, we consider the evolution of cranial capacity in Homo, with the null hypothesis that the changes over time are a result of one process. We employ a new method that uses a resampling approach to address the limitations imposed on the methods of previous studies. To test the null hypothesis,...
BACKGROUND Nonmelanoma skin cancer (NMSC) incidence in patients with vitiligo has not been studied. OBJECTIVE We sought to quantify the incidence of NMSC in patients with vitiligo. METHODS A cohort of 477 patients with vitiligo and no history of NMSC seen in an outpatient academic center between January 2001 and December 2006 was established. All charts for patients with vitiligo were revie...
YPC is a mutant mouse strain with defective hair growth characterized by thin, short hairs and poorly developed hair bulbs and dermal papillae. To identify the gene associated with the phenotype, we performed genome-wide linkage analysis using 1010 backcross progeny and 123 microsatellite markers covering all chromosomes. The mutant locus (ypc) was mapped to a 0.2-cM region in the proximal part...
