Endometrial stromal sarcomas (ESS) are rare malignancies, accounting for less than 10% of uterine sarcomas. Apart from the chromosomal rearrangement t(7;17)(p15;q21), which leads to the JAZF1/SUZ12 chimera, cytogenetic studies have shown that the chromosome band 6p21 is often rearranged in ESS. The translocation partners involved in the 6p21 rearrangements differ among the tumors, but chromosome 7
The cysteinyl-leukotrienes (cysLTs: LTC4, LTD4 and LTE4) have an important pathophysiological role in asthma. They are not only extremely potent bronchoconstrictors, but are also involved in the central mechanisms of the asthmatic inflammation and the subsequent remodelling of the airways. Allergen-induced bronchoconstriction as well as spontaneous exacerbations of asthma are associated with incre
Introduction to the films of Swedish artist and filmmaker Claes Söderquist (b. 1937)
Den 15 mars hoppade Felix Baumgartner från 22 km höjd. Detta var ett steg på vägen att slå det tidigare höjdrekordet: Joe Kittinger hoppade 1960 hoppade från en heliumballong på mer än 3 mils höjd, som en del av USAs rymdprogam. Att man kan komma så högt med en heliumballong, och sedan falla mot jorden, medan temperaturen varierar och luftens densitet och luftmotståndet hela tiden ökar, inbjuder t
