Functional crosstalk between the cohesin loader and chromatin remodelers
Nature Communications, 2022 Chromatin remodelers direct the cohesin loader to nucleosome depleted regions where cohesin accesses chromosomes. Muñoz et al. now show that the cohesin loader in turn is a biochemical activator of a chromatin remodeler, helping to clear ...

A Brownian ratchet model for DNA loop extrusion by the cohesin complex
eLife, 2021 The cohesin complex topologically encircles DNA to promote sister chromatid cohesion. Alternatively, cohesin extrudes DNA loops, thought to reflect chromatin domain formation. Here, we propose a structure-based model explaining both activities.

The large cytoplasmic volume of oocyte
The Journal of Reproduction and Development, 2022 The study of the size of cells and organelles has a long history, dating back to the 1600s when cells were defined. In particular, various methods have elucidated the size of the nucleus and the mitotic spindle in several species.

Frontiers in Genetics, 2021 The formation of hybrid sterility is an important stage of speciation. The voles of the genus Microtus, which is the most speciose genus of rodents, provide a good model for studying the cytological mechanisms of hybrid sterility.

Re-making urban segregation: processes of income sorting and neighbourhood change [PDF]
, 2016 Segregation studies have mainly focused on urban structures as a whole or have discussed specific (gentrifying or renewing) neighbourhoods. The literature suggests that changes in segregation occur primarily through selective migration. In this paper, we

3D numerical investigation of functionally graded concrete
Ho Chi Minh City Open University Journal of Science - Engineering and Technology, 2023 In the design of engineering structures, concrete is assumed to have homogeneously mechanical properties. However, in reality, the concrete material is usually not uniform with respect to the height of structures because segregation mostly occurs during ...

Nature Communications, 2020 Oocyte meiosis must achieve spindle bipolarization without predefined spatial cues. Yoshida et al. demonstrate that spindle bipolarization during meiosis I in mouse oocytes requires kinetochores to prevent chromosome segregation errors, a phenomenon that

The Roma in Turkiye: Segregation in The Labour Market and Income Differentiations
Journal of Economy Culture and Society, 2022 In labour market research, rather than demographic and human capital endowments, ethnicity is considered a major explanatory of segregation in job occupations.
