Measuring nuclear reaction cross sections to extract information on neutrinoless double beta decay
2017
Neutrinoless double beta decay (0v\b{eta}\b{eta}) is considered the best potential resource to access the absolute neutrino mass scale. Moreover, if observed, it will signal that neutrinos are their own anti-particles (Majorana particles). Presently, this physics case is one of the most important research "beyond Standard Model" and might guide the way towards a Grand Unified Theory of fundamental interactions. Since the 0v\b{eta}\b{eta} decay process involves nuclei, its analysis necessarily implies nuclear structure issues. In the NURE project, supported by a Starting Grant of the European Research Council (ERC), nuclear reactions of double charge-exchange (DCE) are used as a tool to extr…
Identidad y competencias interculturales
2014
Resumen basado en el de la publicación Título, resumen y palabras clave en inglés y español Se aborda la interculturalidad en la ciudad de Granada pretendiendo alcanzar los siguientes objetivos: identificar las circunstancias personales y familiares relacionadas con el proceso de integración social de los inmigrantes en Granada, conocer sus expectativas de promoción personal y social, así como identificar el desarrollo de competencias interculturales como base para la constante reconstrucción de la identidad. Tres han sido los colectivos de estudio: inmigrantes magrebíes, latinoamericanos y europeos del este. La metodología utilizada ha sido la entrevista y el cuestionario. En los resultado…
Preliminary health screening and possible pathogen determination in aBufo bufo(Linnaeus, 1758) (Amphibia: Bufonidae) population
2010
The population of the common toad, Bufo bufo, on Jersey (Channel Islands, UK) has undergone a marked decline over recent years. Hypothesized causes for this decline include land use change, pollution, climate change and predation. We examined the carcasses of 97 wild adult common toads for gastrointestinal and pulmonary helminths. In addition, 31 adult toad carcasses were examined for the presence of ranavirus infection, and 212 wild common toads were examined for the presence of infection with the fungus Batrachochytrium dendrobatidis. Three nematode species Rhabdias bufonis, Aplectana macintoshii and Oswaldocruzia filiformis, and one species of cestode, Nematotaenia dispar, were identifie…
Topography of somatostatin gene expression relative to molecular progenitor domains during ontogeny of the mouse hypothalamus
2010
The hypothalamus comprises alar, basal, and floor plate developmental compartments. Recent molecular data support a rostrocaudal subdivision into rostral (terminal) and caudal (peduncular) halves. In this context, the distribution of neuronal populations expressing somatostatin (Sst) mRNA was analyzed in the developing mouse hypothalamus, comparing with the expression pattern of the genes Orthopedia (Otp), Distal-less 5 (Dlx5), Sonic Hedgehog (Shh), and Nk2 homeobox 1 (Nkx2.1). At embryonic day 10.5 (E10.5), Sst mRNA was first detectable in the anterobasal nucleus, a Nkx2.1-, Shh-, and Otp-positive basal domain. By E13.5, nascent Sst expression was also related to two additional Otp-positiv…
Humic acid reduces gonadotropin activity and hormonal sensitivity of frog oocytes
2005
The specific stimulatory effect of sturgeon Acipenser güldenstädti Br. gonadotropic hormone (GTH) on frog Rana temporaria L. oocyte maturation in vitro was investigated in relation to humic acid (HA) concentrations from 12.5 to 50 mg/l. HA was observed to bind to both the follicular membrane of the oocytes and the GTH molecule, reducing the oocytes' hormone sensitivity and maturation ability. It was also shown that HA inactivated GTH, lowering its specific ability to stimulate oocyte maturation.
Thyrotrophin-releasing hormone-a lactation-promoting agent?
1991
Objective— To study the lactational and hormonal responses to nasal administration of thyrotrophin-releasing hormone (TRH) in puerperal women with inadequate lactation. Design— Prospective randomized double-blind placebo-controlled study. Subjects— 19 puerperal women with inadequate lactation (<50% of normal milk yield) on the 5th day postpartum. Interventions— 10 women were allocated to receive TRH administered by a nasal spray of 1 mg, four times daily, between suckling episodes, for 10 consecutive days starting on day 6 postpartum. Nine women were allocated to receive placebo sprays. Main outcome measures— Daily milk yield, serum levels of prolactin and thyroid hormones. Results— Before …
Estudio de los valores de referencia para los parámetros de estrés oxidativo: malondialdehído y glutatión, medidos por cromatografía líquida de alta …
2015
La investigación en estrés oxidativo ha experimentado una expansión masiva en los últimos años. Multitud de datos indican que la producción de especies reactivas en los sistemas biológicos regulan numerosos procesos fisiológicos. La producción descontrolada de estas especies está implicada en el inicio y propagación de diversas patologías. Una aproximación común para la determinación del estrés oxidativo en los sistemas biológicos consiste en la medida del aumento o el descenso de moléculas redox-sensibles que responden a este tipo de estrés. Los biomarcadores de estrés oxidativo usualmente se clasifican en 4 categorías. La primera engloba la detección de oxidantes. Desafortunadamente, la m…
