ME is not widely recognized in the Global as well as the Swedish population at large, and within healthcare, there are no standardized recommended treatments, partly due to the lack of published evidence-based studies. This case study aims to provide insights into how the Swedish healthcare system works, how different clinics and hospitals within it operate and interconnect;and how these contribute to health outcomes after 15 months of treatment.展开更多

On the basis of genome-wide chicken genetic variation map generated by comparing three domestic breeds with wild ancestor and the positions of markers on the genetic linkage map, we found that SNPs rates were similar for all chromosomes while the recombina-tion rates increased in micro chromosomes. In other words no correlation exists in chromosome size. Nevertheless, when we scanned the genome by calculating the values of each characteristic within non-overlapping windows, instead of single value for each chromosomes, the nucleotide diversity was found to be significantly correlated with the recombination rate (r=0.27, P<0.0005). Furthermore, the significant association not only existed between these two features, but also existed between all 6 pairwise combinations of nucleotide diversity, recombination rate, GC content and average gene length. This co-variation is very meaningful for the studies of sequence evolution.展开更多
