Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Q: Context: To compare the frequency of Pap test results in a prospective series of direct to vial ThinPrep tests to a cohort of conventionally prepared tests. To follow-up all test results for a minimum of 2 years and assess performance based on this outcome.', 'All women presenting for either routine screening or colposcopic examination in 2001 were enrolled in the ThinPrep cohort. A similar, population of conventionally prepared tests was extracted from the year 2000 laboratory data. Information on all concurrent and follow-up cervical specimens over the ensuing 2 years was retrieved.', 'The ThinPrep cohort comprised 2288 Pap tests and the conventional, 2211. The frequency of normal [within normal limits (WNL) and benign cellular changes (BCC)] results in the ThinPrep cohort was 6% lower and the frequency of abnormal [> or =atypical squamous cells of undetermined significance (ASCUS)] results was 6.8% higher. Respective ThinPrep and conventional cohort results were 1156 (51%) and 1291 (58%) WNL, 625 (27%) and 561 (25%) BCC, 101 (4%) and 65 (3%) ASCUS, 21 (1%) and 2 (0.1%) atypical glandular cells of undetermined significance, 301 (13%) and 224 (10%) low-grade squamous intraepithelial lesion (LSIL), and 74 (3%) and 40 (2%) high-grade SIL (HSIL) (P < 0.0001). Follow-up was available for nearly 80% of each cohort. LSIL or higher was confirmed in 57.5% (n = 266) of the abnormal ThinPrep and 60.9% (n = 190) of the abnormal conventional tests. The ThinPrep yield of confirmed tests however was almost 50% higher than the conventional test.
Answer: In this population, ThinPrep was superior to the conventional Pap test.

A: Does comparative study of the ThinPrep Pap test and conventional cytology result in a Canadian cohort?

Q: Context: The ability to achieve significant donor engraftment without fully myeloablative conditioning has revolutionized allogeneic stem cell transplantation. These nonmyeloablative approaches may allow extension of this potentially curative modality to an increasing number of patients including those with non-malignant diseases. Although a number of regimens have been explored, the optimal means of conditioning has not been determined.', 'We previously demonstrated that rapamycin (RAPA) has the ability to promote T-cell tolerance even in the presence of costimulation. In the current study, we examine the ability of rapamycin or the calcineurin inhibitor cyclosporine A (CSA) to promote chimerism in a murine haploidentical bone marrow transplantation model. Mice were conditioned with 300 cGy and received either RAPA at 3 mg/kg/day IP, CSA at 20 mg/kg/day IP, or no immunosuppression starting on the day before the transplant and continued for 4 weeks.', 'There was no apparent toxicity, and animals maintained normal blood counts throughout. More importantly, long-term macrochimerism was observed only in the RAPA-treated group.
Answer: These results establish a simple, nontoxic, irradiation-based regimen that facilitates engraftment without ablation. This strategy may prove useful in nonmalignant disorders such as hemoglobinopathies in which moderate levels of donor chimerism could prove curative.

A: Does low-dose radiation plus rapamycin promote long-term bone marrow chimerism?

Q: Context: In obese French Caucasian subjects we previously described a silent UCP3 Tyr99Tyr mutation, associated with body mass index. We hypothesised that an unknown polymorphism in the vicinity of the gene could contribute to obesity.', 'Morbidly obese subjects were screened for mutations in 1 kb upstream from the UCP3 gene. Association studies were done between a variant and obesity in 401 morbidly obese and 231 control subjects.', 'We detected three rare genetic variants and one polymorphism: a +5 G-->A in exon 1, a -155 C-->T, a -439 A insertion and a -55 C-->T located 6 bp from the putative TATA box. This variant was in linkage disequilibrium with the Tyr99Tyr polymorphism. Frequencies of the variant allele at the -55 locus were similar in the obese and control groups (0.23 vs 0.21). The -55 polymorphism was associated with BMI in the obese group (p = 0.0031): BMI was higher in TT than in CC or CT patients. Likewise control subjects with a TT genotype had a higher BMI (p = 0.03). In the obese group, homozygosity for this variant is a risk factor for high BMI (odds ratio: 1:75, p = 0.02). Obese patients were divided into tertiles according to physical activity. In the group with a wild C/C genotype, BMI was negatively associated with physical activity (p = 0.015).
Answer: The C-->T polymorphism in the 5' sequences of the UCP3 gene might contribute to the corpulence in obese and normal weight subjects and alter the benefit of physical activity. The UCP3 gene can be considered as a gene modifying corpulence.

A:
Is a genetic variation in the 5 ' flanking region of the UCP3 gene associated with body mass index in humans in interaction with physical activity?
