Centro de Estudios Avanzados (CEA); Argentina.El impacto social y cultural de las tecnologías de información en la educación universitaria, hace que nos detengamos a repensar el papel de la formación en bibliotecología y en las nuevas herramientas tecnológicas para el aprendizaje colaborativo con las que contamos en el siglo XXI. La incorporación de cualquier tecnología a las actividades áulicas requiere un doble esfuerzo: uno de naturaleza conceptual y otro de carácter instrumental, con el único propósito de concebir nuevas formas de transmitir y acceder al conocimiento para aplicarlas de un modo efectivo en el aula. El presente trabajo pretende dar una visión sobre cómo los docentes de la Licenciatura en Bibliotecología y Documentación utilizan las tecnologías de la información para la enseñanza en nuestra área y cómo se van incorporando, poco a poco, nuevas herramientas para el aprendizaje. Se busca reflexionar acerca de la formación con TIC de las Escuelas de Bibliotecología de las Universidades Nacionales. En el campo disciplinar de la Bibliotecología y Documentación, las tecnologías se han impuesto con gran fuerza desde la formación de los profesionales hasta en el trabajo cotidiano con la información y sus usuarios, por lo que resulta necesario abordar dicha formación como un proceso complejo que entraña una interacción entre el que se forma, el formador, su objeto de estudio y su ámbito de trabajo. En la primera parte del trabajo se expone el nuevo rol del profesional de la información, la educación superior y el docente frente a las TIC y en una segunda instancia, se presentan y analizan las competencias con que deberían contar los docentes en relación a lo instrumental, cognitivo, actitudinal y político para lograr que las TIC formen parte de su entorno, a través del cual se generen nuevos espacios para la enseñanza y el aprendizaje.Fil: Ladrón de Guevara, María Carmen.

Background: Sphyrna lewini, is a semi-oceanic and cosmopolitan species globally distributed throughout tropical and warm temperate seas. In the northeastern tropical Pacific, this specie represents an important contribution to the biomass of artisanal and small-scale fisheries. Goals: In this study the aim was to obtain information about length frequency distribution and reproductive aspects of S. lewini, in Oaxaca, Mexico. Methods: Samples were taken from August 2001 to December 2007 in four landing sites of the artisanal fleet on the coast of Oaxaca. Results: Samples were collected 388 females and 434 males. Total length ranged from 44-308 cm for males and from 44-332 cm for females. The catches were made up of neonates (24.3%, 44-74 cm), juveniles (42.2%, 75-170 cm) and adults (33.5%, > 170 cm). The sex ratio shows differences by size, and season. The greatest catches were recorded in the rainy season (85.5%), with a predominance of juveniles and adults, and a higher proportion of males. In the dry season (15.5%) were recorded with a predominance of larger sizes >100 cm in both sexes. The females reached sexual maturity (TL50) at 198.8 cm and the males at 181 cm, based on characteristics and measurements of reproductive organs. A total of 37 gravid females with sizes between 175 and 281 cm were registered, from April to August. Gravid females had between 15-42 embryos, varying from 44-54 cm. Conclusion: S. lewini was present year round in the study area with the greatest catch from April to September, the season when pregnant females were present. Antecedentes: Sphyrna lewini, es una especie semi-oceánica y cosmopolita distribuida en aguas tropicales y templadas cálidas.

Enhancement of adult hippocampal neurogenesis by spatial memory training and its effect on the maintenance of cocaine-contextual memory

Aims:Modulation of hippocampal memories related with cocaine addiction such as cocaine-context associations could have important clinical implications. It has been asserted that learning-related experiences promote hippocampal plasticity enhancing adult hippocampal neurogenesis (AHN). Here we aimed to evaluate (1) the stimulation of AHN using a spatial learning task dependent on the hippocampus and (2) whether spatial learning reduces the long-term maintenance and reinstatement of previously acquired cocaine-associated contextual memories. Methods: Male C57BL/6J mice were first submitted to a cocaine induced conditioned place preference paradigm (CPP). Then, bromodeoxyuridine (BrdU) was administered in order to label newborn neurons. One week after the last BrdU injection, a group of mice were trained in a spatial learning task using the Morris water maze while control animals received a non-hippocampal training or stayed undisturbed in their home-cages. Twenty seven days after conditioning, mice were tested for CPP retention and extinction. Finally, a cocaine priming-induced reinstatement of drug seeking was performed. Results: Animals trained in the spatial learning task exhibited a lower long-term CPP retention memory. In addition, cocaine-induced CPP reinstatement was attenuated in trained animals. Immunohistochemistry showed an increment in the BrdU+ cells in the hippocampus of trained animals in contrast with control animals. Conclusions: Spatial memory training using the Morris water maze constitutes a tool to promote the survival of newborn neurons in the hippocampus. Furthermore, stimulation of AHN might be a neurobiological mechanism by which spatial learning reduces the long-term maintenance of previous cocaine-context associative memory.

Influence of neurogenic improvement strategies on extinction and reinstatement of cocaine-induced conditioned place preference

AIMS: Modulation of adult hippocampal neurogenesis (AHN) has been shown to influence the maintenance of drug-context associations. We aimed to study whether the enhancement of AHN by using a water maze spatial learning task (WM), solely or under conditions of neurogenesis stimulation (forced treadmill exercise), could facilitate extinction and prevent primed reinstatement of cocaine-context associations. METHODS: Adult male C57BL/6J mice (N=37) were trained in the Conditioned Place Preference (CPP) paradigm with ascending doses of cocaine (2, 4, 8, 16 mg/kg/d) and subsequently received bromodeoxyuridine (BrdU) injections to label newborn neurons. Then, experimental groups were submitted to 12 days of scheduled exercise and/or 8 days of spatial training in the WM. Sedentary and/or untrained groups stayed undisturbed in their home cages. When BrdU+ cells reached maturation (~6 weeks-old), all mice were tested for CPP memory retrieval. Finally, animals were submitted to forced CPP extinction and tested for CPP extinction and cocaine-primed reinstatement. RESULTS: Animals submitted either to the scheduled exercise protocol, training in the WM or both strategies combined, required fewer sessions to extinct cocaine-CPP associations than control animals. Furthermore, animals submitted to both environmental strategies showed a reduced reinstatement when compared to sedentary animals. These effects are partially related to the functional integration of the newborn neurons in the hippocampus. CONCLUSIONS: Both environmental strategies, alone and combined, can reduce the long-term persistence of cocaine-context associations, being AHN associated with these beneficial effects.PSI2017-82604; PRE2018-085673; 08-2021-AREA3; B1-2020_06;Posdoc_21_00222; Posdoctoral_a32.

Training memory without aversion: Appetitive hole-board spatial learning increases adult hippocampal neurogenesis.

Learning experiences are potent modulators of adult hippocampal neurogenesis (AHN). However, the vast majority of findings on the learning-induced regulation of AHN derive from aversively-motivated tasks, mainly the water maze paradigm, in which stress is a confounding factor that affects the AHN outcome. Currently, little is known regarding the effect of appetitively-motivated training on AHN. Hence we studied how spatial learning to find food rewards in a hole-board maze modulates AHN (cell proliferation and immature neurons) and AHN-related hippocampal neuroplasticity markers (BDNF, IGF-II and CREB phosphorylation) in mice. The 'Trained' mice were tested for both spatial reference and working memory and compared to 'Pseudotrained' mice (exposed to different baited holes in each session, thus avoiding the reference memory component of the task) and 'Control' mice (exposed to the maze without rewards). In contrast to Pseudotrained and Control mice, Trained mice reduced the number of proliferating hippocampal cells but they notably increased their population of immature neurons assessed by immunohistochemistry. This evidence shows that hole-board spatial reference learning diminishes cell proliferation in favor of enhancing young neurons' survival. Interestingly, the enhanced AHN in the Trained mice (specifically in the suprapyramidal blade) positively correlated with their reference memory performance, but not with their working memory. Furthermore, the Trained animals increased the hippocampal protein expression of all the neuroplasticity markers analyzed by western blot. Results show that the appetitively-motivated hole-board task is an useful paradigm to potentiate and/or investigate AHN and hippocampal plasticity minimizing aversive variables such as fear or stress.Universidad de Málaga.
