Uzmanības deficīta un hiperaktivitātes sindroma ietekme uz skolas uzvedību un sociālajām prasmēm skolas vecuma bērniem
2019
Mūsdienu klasēs, daudzi pedagogi saskaras ar „ārpus kontroles bērniem”. Bērniem, kuriem ir uzmanības deficīts vai hiperaktivitātes sindroms (turpmāk tekstā UDHS), ir neiroloģiski traucējumi, kas ietekmē viņu spēju kontrolēt savu uzvedību un pievērst uzmanību uzdevumiem. Bērni ar UDHS rada īpašu iedzīvotāju grupu ar dažādām vajadzībām izglītības vidē. Izpētītajā pētījumā, tika pievērsta uzmanība uzmanības deficīta un hiperaktivitātes traucējumiem. Pētījuma mērķis bija izpētīt un analizēt dažādas pieejas UDHS, kas saistītas ar problēmām ar vidusskolēniem. Literatūras pārskatā aplūkotās tēmas, ietver dažādas teorijas un kopīgas intervences, ņemot vērā UDHS. Šajā darbā, tika izmantota kvalitatī…
Homophobic bullying and preventive actions at school: from laws to gender studies in Italy
2019
The evolution of thought relating to sexual orientation and the greater visibility of gay and lesbian people, at media level also, haven’t been efficient for the revisiting of homosexual rendering from public acceptance and for a cultural transformation. The violent events on young homosexual students urge to reflect on the need that trainers should introduce educational models capable of providing different models of gender identification, fighting the stereotype that tries to substitute the reality itself. The homophobic bullying is intended as a fight to safety and well-being of young students. A multi-disciplinary and network approach seems to be for health practitioners a valid startin…
Impacto científico en los artículos sobre aplicaciones terapéuticas de las prácticas orientales cuerpo-mente (2006-2010)
2014
Global research on mind-body therapies is analysed, by focussing on scholarly articles on three Eastern disciplines (yoga, tai chi and qi gong) and three procedures (meditation, breathing exercises and relaxation). The bibliographic research was done using the Scopus database. The search was limited to the biomedical areas and to the years 2006-2010. We have analysed 2,363 articles published by 959 different journals. They were written by 6,583 authors from 2,162 institutions in 65 countries. Indicators of scientific productivity and impact were calculated for institutions, countries and subject areas, and the collaboration between authors and institutions was also determined. We have obser…
Are Public Subsidies to Encourage Young Farmers Effective? Case Study of a First-Time Farm Set Up by a Young Female Farmer in the Valencian Region of…
2021
Generational renewal and the incorporation of women into the rural world are fundamental for the sustainability and modernisation of the agricultural sector. Hence the special government protection granted to the sector, which appears in both European legislation on rural issues and in the global strategy of the 2030 Agenda and the Sustainable Rural Development Goals involving a commitment to measures aimed at helping young farmers to set up agricultural holdings and especially at encouraging women to engage in farm management. In the case of Spain, this is nothing new, given that Law 35/2011 on the Shared Ownership of Agricultural Holdings became a veritable revolution in terms of gender i…

Localized expression of Strim1, a novel member of the TRIM-containing family, guides the skeletal morphogenetic program of the sea urchin embryo
2011
The building of the skeleton in the indirect developing sea urchin embryo is a complex morphogenetic process that is executed by the Primary Mesenchyme Cells or PMCs (Ettensohn et al, 1997; Wilt 2002). It is well known that the PMCs acquire most of the positional and temporal information from the overlying ectoderm for skeletal initiation and growth (Armstrong 1993; Cavalieri et al, 2003; Röttinger et al, 2008). In this study, we analyze the function of a novel gene, encoding for a tripartite motif-containing (TRIM) protein denoted strim1, that adds up to the list of genes constituting the epithelial-mesenchymal signaling network. We show that strim1 is expressed in ectoderm regions adjacen…
Vanadium Toxicity Monitored by Fertilization Outcomes and Metal Related Proteolytic Activities in Paracentrotus lividus Embryos
2022
Metal pharmaceutical residues often represent emerging toxic pollutants of the aquatic environment, as wastewater treatment plants do not sufficiently remove these compounds. Recently, vanadium (V) derivatives have been considered as potential therapeutic factors in several diseases, however, only limited information is available about their impact on aquatic environments. This study used sea urchin embryos (Paracentrotus lividus) to test V toxicity, as it is known they are sensitive to V doses from environmentally relevant to very cytotoxic levels (50 nM; 100 nM; 500 nM; 1 µM; 50 µM; 100 µM; 500 µM; and 1 mM). We used two approaches: The fertilization test (FT) and …
cis-Regulation and chromatin dynamics of the hbox12 gene during the embryogenesis of Paracentrotus lividus.
2014
The GRN specifying the dorsal-ventral (D-V) axis of the sea urchin embryo is currently under investigation. An early input for D-V polarity is given by a redox gradient probably generated by an asymmetrical distribution of maternal mitochondria (1). Only on the future ventral side, the oxidizing environment induces the expression of the nodal gene, an essential regulator of D-V polarization (2). By contrast, on the future dorsal side, a reducing environment activates the hypoxia inducible factor (HIF-1α) (3). The hbox12 transcription repressor is an early marker of the dorsal side of the embryo, in which it negatively regulates the expression of nodal (4, 5). Interestingly, by in silico ana…
Genome wide mapping of the MBF-1 binding sites during embryogenesis of the sea urchin reveals it is a chromatin organizer.
2015
The Zinc-finger MBF1 factor is a transcription activator involved in the expression of the early histone genes during development of the sea urchin embryo (1). The DNA-binding domain of MBF1 shares high sequence similarity with that of the CTCF chromatin organizer but, unexpectedly, extensive in silico analysis failed to identify the sea urchin CTCF ortholog (2, 3). This led us to speculate that MBF1 could have co-opted the function of CTCF during evolution of the echinoderms. To support this hypothesis, we performed the genome-wide MBF1-binding sites mapping in the P. lividus genome, by chromatin immunoprecipitation coupled to next generation sequencing (ChIP-Seq). We observed that MBF1 bi…
Exposure to cytotoxic concentrations of manganese and effects on development
2009
Manganese is one of the most abundant metals present in nature in trace amounts, which is accumulated and utilized by all forms of life. It plays a multitude of biological roles, but exposure of cells/organisms to high levels causes toxicity. In the marine environment, increasing concentrations of bio-available ions often result from anthropogenic activities, and, consequently, manganese represents a new emergent factor in environmental contamination. To study cyto-toxicity of manganese on development, we used an excellent model system as sea urchin embryos Paracentrotus lividus. In this work, we show results from two-dimensional gel electrophoresis (2DE) analysis that highlighted qualitati…
