- We report a high-quality draft sequence of the genome of the horse ( Equus caballus). The genome is relatively repetitive but has little segmental duplication. Chromosomes appear to have undergone few historical rearrangements: 53% of equine chromosomes show conserved synteny to a single human chromosome. Equine chromosome 11 is shown to have an evolutionary new centromere devoid of centromeric satellite DNA, suggesting that centromeric function may arise before satellite repeat accumulation. Linkage disequilibrium, showing the influences of early domestication of large herds of female horses, is intermediate in length between dog and human, and there is long-range haplotype sharing among breeds.

Tidskriftsartikel (refereegranskat)abstract
- On January 25, 2018 a 5-car train derailed in Pioltello, 10 kilometers North-East of Milano City. A standardized post-hoc form was distributed to the hospitals involved in the management of the victims and allowed for an evaluation of the response to the incident.The management of the incident by EMS (Emergency Medical System) was effective in terms of organization of the scene and distribution of the patients, although the time for the first severe patient to reach the closest appropriate hospital was very long (2 hours). This can be partially explained by the extrication time.None of the alerted hospitals exceeded their capacity, as patients were distributed carefully among the hospitals. The overall outcome was quite satisfactory; no deaths were reported except for those on scene. Some responding hospitals reported that there was an over-activation based on the services ultimately needed. However this is common in MCIs, as an over-activation is preferable to an under-estimation. To address this concern, as more data are available, activation should be scaled down based on a plan established prior to it; this mechanism of scaling down seems to have failed in this event.It is of note that the highest performing hospitals underwent recently to an educational program on MCI management.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Various occupational exposures have been monitored by chromosomal aberrations, sister chromatid exchanges and micronuclei in peripheral blood lymphocytes. During the last decade, epidemiological studies have evaluated whether any of these markers foreshadows cancer risk. Results from Nordic, Italian and Czech cohorts support an approximately twofold cancer risk among subjects with high frequencies of chromosomal aberrations, but no such association was seen for any of the other biomarkers. The estimated attributable proportion of high frequencies of chromosomal aberrations for overall cancer risk is 0.25, which gives a quantitative estimate of the chromosomal aberration assay as a surrogate endpoint of cancer. The results from the different cohort studies are contradictory in terms of whether or not the predictive value of the chromosomal aberration assay for cancer is differential with respect to occupational exposure to clastogens. Genetic susceptibility factors are known to affect the frequency of chromosomal aberrations in peripheral blood lymphocytes. It is quite possible that such factors might also affect the frequency of chromosomal aberrations directly or might modify the impact of exposures to clastogen. There is no other biomarker for general cancer risk that is applicable to healthy subjects from the general population with such a high attributable proportion. However, at present only a simplified and tentative model can be proposed for the role of the chromosomal aberration marker in the pathogenesis of cancer.
