In order to estimate the diversity of embryo cleavage relatives to embryo progress (blastocyst formation), time-lapse imaging data of preimplantation human embryo development were used. This retrospective study is focused on the topographic features and time parameters of the cleavages, with particular emphasis on the lengths of cleavage cycles and the genealogy of blastomeres in 2- to 8-cell human embryos. We have found that all 4-cell human embryos have four developmental variants that are based on the sequence of appearance and orientation of cleavage planes during embryo cleavage from 2 to 4 blastomeres. Each variant of cleavage shows a strong correlation with further developmental dynamics of the embryos (different cleavage cycle characteristics as well as lengths of blastomere cycles). An analysis of the sequence of human blastomere divisions allowed us to postulate that the effects of zygotic determinants are eliminated as a result of cleavage, and that, thereafter, blastomeres acquire the ability of own syntheses, regulation, polarization, formation of functional contacts, and, finally, of specific differentiation. This data on the early development of human embryos obtained using noninvasive methods complements and extend our understanding of the embryogenesis of eutherian mammals and may be applied in the practice of reproductive technologies.

Abstract The project presented here deals with a typical human means of communication – writing. The aim of the project is to map the developmental dynamics of handwriting from the first to the fifth grade of primary school. The question remains topical because of the fact that several systems of writing have been used in the past few years. Our project focuses on comparing the systems of joined-up handwriting (the standard Latin alphabet) and the most widespread form of printed handwriting: Comenia Script. The research can be marked as sectional; pupils took a writing exam at the beginning and at the end of the 2015/2016 school year. The total number of respondents was 624 pupils, evenly distributed according to the school year, system of writing and gender. To evaluate handwriting, the evaluation scale of Veverková and Kucharská (2012) was adjusted to include a description of phenomena related to graphomotor and grammatical aspects of writing, including the overall error rate and work with errors. Each area that was observed included a series of indicators through which it was possible to create a comprehensive image of the form handwriting took in the given period. Each indicator was independently classified on a three-point scale. Thanks to that, a comprehensive image of the form of writing of a contemporary pupil emerged.

AbstractOxytocin (OXT) and arginine vasopressin (AVP) support a broad range of behaviors and homeostatic functions including sex-specific and context-appropriate social behaviors. Although the alterations of these systems have been linked with social-related disorders such as autism spectrum disorder, their formation and developmental dynamics remain largely unknown. Using novel brain clearing techniques and 3D imaging, we have reconstructed the specification of oxytocinergic and vasopressinergic circuits in the developing mouse brain with unprecedented cellular resolution. A systematic quantification indicates that OXT and AVP neurons in the hypothalamus display distinctive developmental dynamics and high cellular plasticity from embryonic to early postnatal stages. Our findings reveal new insights into the specification and consolidation of neuropeptidergic systems in the developing CNS.

The migration of women or female migration has emerged as an important field of research within the larger domain of migration studies and is being extensively explored under various disciplines. This growing trend can be attributed to some major developments in international migration such as rising numbers of women migrants, growth of women-centric occupations, migration of women in an independent capacity, women-related legislations and growth of gendered perspectives on various issues. These factors together increased the visibility of women in the migration process and have given rise to what has been termed the ‘feminization of migration’. This paper explores the various nuances of the feminization of migration and aspects of female migration focusing on India. It begins with an overview of the growing numbers of women in the migratory flows and goes on to determine that despite the rising numbers and increased participation of women in the developmental dynamics of migration, they remain increasingly vulnerable and exposed to exploitation. The paper also highlights some of the critical policy decisions of the Government of India. The paper concludes that feminization of migration has undoubtedly increased the visibility of women in the migration discourse but much more needs to be done in terms of generating appropriate data, highlighting women’s role in the developmental process, evolving policies for ensuring their protection and security and above all empowering them and increasing their participation in the labour market.
