Newer recombinations overwrite
traces of past ones and our results indicate more recent recombinations are detected by IRiS with greater sensitivity. IRiS analysis of the MS32 region, previously studied using sperm typing, showed good concordance with estimated recombination rates. We also applied IRiS to haplotypes for 18 X-chromosome regions in HapMap Phase 3 populations. Recombination events detected for each individual were recoded as binary allelic states and combined into recotypes. Principal component analysis and multidimensional scaling based on recotypes reproduced the relationships between the eleven HapMap Phase III populations that can be expected from known human population history, thus further validating IRiS. We believe that our new method will contribute to the study of the distribution of recombination events across the genomes and, for the first time, it will allow the use of recombination as genetic Blebbistatin order marker to study human genetic variation.”
“Introduction and objectives: In primary angioplasty, the interval between first medical contact (FMC) and reperfusion should be less than 120 minutes. The time to reperfusion varies depending on where FMC is established. Recent studies suggest longer times in patients presenting in off-hours. The objective is
to evaluate the time intervals between the onset of symptoms and reperfusion according to where the FMC occurs and time of day of Selleckchem MK-5108 patient presentation.
Methods: Prospective observational study of acute myocardial infarction patients treated with primary angioplasty AZD1208 mw (February 2007 to May 2009). Depending on the FMC, patients were classified as belonging to the hospital group (hospital with primary angioplasty), the transfer group (hospital
without primary angioplasty), or the emergency medical system (EMS) group (out-of-hospital care). For each group, the prehospital delay, diagnostic delay, delay in activation and/or transfer, and procedure delay were recorded.
Results: Primary angioplasty was performed in 457 patients: 155 in the hospital group, 228 in the transfer group and 72 in the EMS group. The median [interquartile range] door-to-reperfusion times were 80 [63-107], 148 [118-189] and 81 [66-98] minutes, respectively (P < .0001). The transfer group showed a greater delay in diagnosis (P <. 0001) and delayed activation and/or transfer (P <. 0001). The EMS group had the shortest total time due to a reduced prehospital delay (P = .001). No difference was found with regard to the time of presentation (P = .42).
Conclusions: Transfer group patients were treated later and EMS group patients much earlier. There were no differences in association with the time of presentation. The identification of inappropriate delays should enable the introduction of measures to improve the efficiency of treatment. (C) 2011 Sociedad Espanola de Cardiologia.
