Cohesin is a multiprotein complex that not only is essential for cell division but also has key roles in genome organization that underpin its gene regulatory *** mutations of genes encoding cohesin subunits occur in myeloid malignancies at 10%–12%(Kon et al.,2013),and the frequency of cohesin mutation in Down syndrome-associated megakaryoblastic leukaemia is even higher(~50%)(Yoshida et al.,2013).Cohesin insufficiency reinforces stem cell programmes and impairs differentiation in haematopoietic stem cells(Mazumdar et al.,2015;Mullenders et al.,2015;Viny et al.,2015).The STAG2 subunit of cohesin is the most frequently mutated in myeloid malignancies(Kon et al.,2013).In contrast to other cohesin subunits,complete loss of STAG2 is tolerated due to partial compensation by ***2 and STAG1 have redundant roles in cell division(Benedetti et al.,2017;van der Lelij et al.,2017).However,cohesin-STAG1 and cohesin-STAG2 have non-redundant roles in facilitating 3D genome organization to delineate tissue-specific gene expression(Kojic et al.,2018).

Bacterium Providencia rettgeri YL was found to exhibit an unusual ability to heterotrophically nitrify and aerobically denitrify various concentrations of ammonium （NH4^＋-N）. In order to further understand its removal ability, several experiments were conducted to identify the growth and ammonium removal response at different carbon to nitrogen （C/N） mass ratios, shaking speeds, temperatures, ammonium concentrations and to qualitatively verify the production of nitrogen gas using gas chromatography techniques. Results showed that under optimum conditions （C/N 10, 30℃, 120 r/min）, YL can significantly remove low and high concentrations of ammonium within 12 to 48 h of growth, respectively. The nitrification products hydroxylamine （NHzOH）, nitrite （NO2^-） and nitrate （NO3^-） as well as the denitrification product, nitrogen gas （N2）, were detected under completely aerobic conditions.

The Moon

Acta Geochimica 2016年第1期35卷 1-13页

作者： ross taylor australian national university CanberraAustralia

Recent geochemical and geophysical data from the Moon enable a revision of earlier interpretations regarding lunar origin, structure and bulk composition. Earth and Moon show many similarities among their isotopic compositions, but they have evolved in totally dissimilar ways, probably related to the deficiency of water and volatile elements in the Moon as well as the vast differences in size and internal pressure. Some global geochemical differences from the Earth such as volatile depletion based on K/U ratios have been established. However, all current lunar samples come from differentiated regions, making the establishment of a bulk composition more reliant on bulk geophysical properties or isotopic similarities; it remains unclear how the latter arose or relate to whole Moon composition. The lack of fractionation effects among the refractory and super-refractory elements indicates that the proto-lunar material seems unlikely to have been vaporized while the presence of volatile elements may place lower limits on proto-lunar temperatures. The apparent lack of geochemical evidence of an impacting body enables other possible impactors, such as comets, to be considered. Although the origin of the Moon remains currently unknown, it is generally believed that the Moon originated as the result of a giant impact on the Earth.
