Gene expression profiles uncover individual identities of gnathal neuroblasts and serial homologies in the embryonic CNS of Drosophila.

2015

The numbers and types of progeny cells generated by neural stem cells in the developing CNS are adapted to its region-specific functional requirements. In Drosophila, segmental units of the CNS develop from well-defined patterns of neuroblasts. Here we constructed comprehensive neuroblast maps for the three gnathal head segments. Based on the spatiotemporal pattern of neuroblast formation and the expression profiles of 46 marker genes (41 transcription factors), each neuroblast can be uniquely identified. Compared with the thoracic ground state, neuroblast numbers are progressively reduced in labial, maxillary and mandibular segments due to smaller sizes of neuroectodermal anlagen and, part…

Water: The First Archaic Mutagen of Evolution, the Adoptive Mother of Currently Nucleic Acids

2016

It would be intuitive to think that for the evolutionary onset of nucleic acids, and even before of their monomeric constituents, the water was crucial. Within the series of evolutions which start from the origin of the universe and still cannot, by definition, be considered concluded, certainly among the geothermal evolution end and the beginning of the chemical one, on Earth, the moment was favorable for the arrival of the first proto-nucleotides: from underground deposits of methanehydrate [1] and phosphate, with the support of all known pre-biotic physical-chemical conditions, were made the monomeric components of nucleic acids. The cradle of nucleic acids does not seem to have been so …

Does Pasteurized Donor Human Milk Efficiently Protect Preterm Infants Against Oxidative Stress?

2019

International audience; Pasteurized donor human milk (DHM) is the preferred alternative for infant nutrition when own mother's milk (OMM) is unavailable. Whether DHM is an efficient means for protecting preterm infants from oxidative stress remains unknown. We quantified a panel of oxidative stress biomarkers in urine samples from preterm infants (≤32 weeks of gestation and a birth weight ≤1500 g) receiving ≥80% of feeding volume as either DHM or OMM. The noninvasive in vivo assessment of oxidative stress showed no statistically significant difference between both groups at the time when full enteral nutrition (150 mL/kg body weight) was achieved and until hospital discharge. In addition, t…

Kinship, acquired and inherited status, and population structure at the Early Bronze Age Mokrin necropolis in northern Serbia

2020

AbstractTwenty-four ancient genomes with an average sequencing coverage of 0.85±0.25 X were produced from the Mokrin necropolis, an Early Bronze Age (2,100-1,800 BC) Maros culture site in Serbia, to provide unambiguous identification of biological sex, population structure, and genetic kinship between individuals. Of the 24 investigated individuals, 15 were involved in kinship relationships of varying degrees, including 3 parent-offspring relationships. All observed parent-offspring pairs were mother and son. In addition to the absence of biological daughters, we observed a number of young women and girls with no biological relatives in our sample. These observations, together with the high…

The clarification of complete cell lineages, which are produced by specific stem cells, is fundamental for understanding mechanisms, controlling the generation of cell diversity and patterning in an emerging tissue. In the developing Central Nervous System (CNS) of Drosophila, neural stem cells (neuroblasts) exhibit two periods of proliferation: During embryogenesis they produce primary lineages, which form the larval CNS. After a phase of mitotic quiescence, a subpopulation of them resumes proliferation in the larva to give rise to secondary lineages that build up the CNS of the adult fly. Within the ventral nerve cord (VNC) detailed descriptions exist for both primary and secondary lineag…

Forbidden option or planned decision? Physically disabled women’s narratives on the choice of motherhood

2016

This narrative study explores personal narratives by disabled women on their choice to become a mother. Eleven Finnish physically disabled mothers were interviewed. The interview data were analysed using Greimas’ actant model. The women produced three types of narratives about their journeys to motherhood: compensation, forbidden option and planned choice. In these narratives, the disabled women struggled with the disabling, oversimplifying and suppressive cultural master narratives of ‘good’ motherhood. Through the narratives, the women distanced themselves from these dominant cultural narratives and constructed strong agency for themselves as mothers. peerReviewed

Validación de un instrumento de evaluación del comportamiento sexual de personas con discapacidad intelectual para padres (ECS-PA)

2019

La reciente normalización de la sexualidad y de los derechos sexuales entre las personas con Discapacidad Intelectual (DI) ha hecho que se incremente el número de iniciativas dirigidas a mejorar sus conocimientos y habilidades mediante programas de educación afectivo-sexual pero dichos programas requieren instrumentos de evaluación fiables que permitan identificar sus necesidades y puedan ser sensibles al cambio tras la intervención. En dicha valoración deben confluir sus percepciones, las de los profesionales que se ocupan de ellos y las de sus padres para asegurar la veracidad de la información obtenida, pero lamentablemente carecemos de instrumentos psicométricos válidos y fiables tanto …

Analysis of surrogacy motherhood as a new technology in the biomedical and legal-philosophical field: technical advance, human recoil

2019

[EN] Surrogate motherhood is a question that has appeared in recent times, with increasing incidence, at present. The economic, political and media powers have brought a strictly technical concept to the public in order to familiarize them with this technique. This strategy has been based on the natural tendency to consider that any technological advance is good in itself, so that they have not been reviewed and made available to the citizens, in a reasonable manner, none of the issues that should be dealt with this technique. Thus, it is worth making a study of the regulations and jurisprudence of the assumptions that have been taking place and considering the reality that this formulation…

Cuestiones varias en torno a la determinación de la filiación por doble paternidad

2018

The article 7.3 of the law 14/2006, of May 26 on technologies of human assisted reproduction establishes the possibility of determining legally the double maternity of married women and not separated legally or of fact, when the not biological mother consents that filiation decides to his favor the respect of the born son of his spouse. In the suppositions not regulated in the mentioned rule the Supreme Court in relation with equal women?s homosexuality in judgment of December 5, 2013 and January 15, 2014 applies the civil code and allows to determine judicially the maternity by means of the exercise of an action of claim for possession of status foreseen in the article 131. In the present …

Educación compensatoria : aprendizaje temprano, éxito posterior : (II: el Carolina Abecedarian Project)

2014

Este es un estudio de revisión en el que se analizan las investigaciones que evalúan los efectos a lo largo del tiempo del programa de educacióntemprano Abecedarian Project (ABC). El ABC es un programa compensador preventivo de 0-5 años y entresacados de madres de alto riesgo. El grupo experimental (E) recibe tratamiento preescolar intensivo, no el control (C). Se prolongó escolarmente hasta los 8 años, subdividiéndose ambos grupos: Dos -EE y CE- recibieron tratamiento intensivo; otros (EC y CC) convencional. Fueron medidos hasta los 21. Resultados: Los jóvenes adultos, tratados preescolarmente, mejoraron en rendimiento mental, lector y matemático; alcanzaron mayores instrucciones y presenc…
