Modelo educativo aula invertida para la enseñanza de la Herencia Cuantitativa en las Ciencias Agropecuarias

Trabajo Final (Especialización en Tecnologías Multimedia para Desarrollos Educativos) -- UNC- Facultad de Ciencias Agropecuarias, 2022En la actualidad las personas jóvenes se relacionan y sociabilizan a través de las redes, el acceso a un teléfono móvil por parte de los más pequeños es casi una constante en nuestra vida cotidiana. Los mismos constituyen una manera de crear y formar personalidad. La tecnología revolucionó el proceso de aprendizaje; diferentes ambientes educativos se encuentran con tal dilema, ¿el celular o el libro? Para lograr la verdadera integración de la tecnología en la educación es de suma importancia el desarrollo de competencias digitales que permiten a los estudiantes interactuar, crear y aprender desde diversas plataformas, promoviendo la participación durante las clases. Tanto docentes como sus estudiantes van creciendo en su conocimiento en las áreas de la informática y la navegación dentro de la web, lo que les permite alcanzar los conocimientos y habilidades para crear contenido digital. Una de las formas de potenciar los procesos de enseñanza y aprendizaje de la Genética dentro de las Ciencias Agropecuarias, es a través de una visión constructivista, mediante la selección de distintas estrategias que permitan lograr una respuesta superadora en relación a la metodología tradicional. Por lo tanto, diseñar un esquema combinado entre lo virtual y lo presencial puede resultar en un mejor aprovechamiento de las habilidades que los jóvenes poseen. El presente trabajo propone utilizar el modelo pedagógico denominado clase invertida para la enseñanza del tema Herencia Cuantitativa. Se trata de un tema de suma importancia dentro del programa la asignatura Genética. Esta materia, pertenece al Ciclo de Conocimientos Básicos dentro de las carreras de Ingeniería Agronómica y Zootecnista dictadas en la Facultad de Ciencias Agropecuarias de la Universidad Nacional de Córdoba (FCA-UNC). El aporte de este trabajo es brindar una propuesta de aula invertida que permitirá a los alumnos realizar lecturas y actividades previas útiles en la construcción del conocimiento de la Herencia Cuantitativa.Fil: Londero, Walter Hugo.

Carotid artery stenting protected with an emboli containment system

Background and Purpose—Fear of distal embolization and stroke has aroused concern regarding carotid stenting. Devices to protect the cerebral circulation may make carotid stenting safer. Methods—A multidisciplinary study group tested a balloon occlusion-aspiration emboli entrapment device in conjunction with carotid stenting. The device consists of an elastomeric balloon on a steerable wire with a detachable adapter that inflates and deflates the distal temporary occlusion balloon. An aspiration catheter is used to remove trapped emboli after stenting and before occlusion balloon deflation. Results—Seventy-five patients with severe internal carotid artery stenosis were treated with stents deployed with this cerebrovasculature protection system. All 75 patients (100%) had grossly visible particulate material aspirated, and all were treated successfully without major or minor stroke or death at 30 days. Preintervention stenosis was 81 10%, and residual stenosis was 5 7%. Nine patients (12%) had angiographic evidence of thrombus before intervention, but no patient had thrombus or vessel cutoff after the procedure. Four patients (5%) developed transient neurological symptoms during protection balloon occlusion, but symptoms resolved with balloon deflation. The 22 to 667 particles aspirated per patient ranged from 3.6 to 5262 m in maximum diameter (mean, 203 256 m). These particles included fibrous plaque debris, lipid or cholesterol vacuoles, and calcific plaque fragments. Conclusions—Protected carotid stenting was performed successfully and safely in this study early in the experience with cerebrovascular protection devices. Particulate emboli are frequent with stenting, and cerebral protection will likely be necessary to minimize stroke. Randomized trials comparing protected carotid stenting with endarterectomy are warranted. (Stroke. 2002;33:1308-1314.)Fil: Whitlow, Patrick L.. No especifíca;Fil: Lylyk, Pedro.

Surgical treatment by electrical stimulation of the auditory cortex for intractable tinnitus

Tinnitus is a public health issue in France. Around 1% of the population is affected and 30,000 people are handicapped in their daily life. The treatments available for disabling tinnitus have until now been disappointing. We are reporting on the surgical treatment by electrical stimulation of the auditory cortex of a female patient affected by disabling tinnitus that resisted classical treatments. The tinnitus appeared suddenly 10 years ago after a left ear tympanoplasty. The acouphenometry measures revealed a bilateral tinnitus, predominant on the right side, constant, with high frequency (6000 Hz). Transcranial magnetic stimulation (TMS) was performed at first with several supraliminal and infraliminal protocols. This showed promising results. Anatomic and functional magnetic resonance imaging (fMRI) of the auditory cortex before and after repetitive TMS (rTMS) demonstrated a modification of the cortical activity and where the ideal location for a cortical electrode might be, to straddle primary and secondary auditory cortex.After these investigations, two quadra polar electrodes (Resume, Medtronic Ltd, Hertfordshire, UK), connected to a stimulating device implanted under the skin (Synergy, Medtronic Ltd), were extradurally implanted. The surgical procedurewas similar to the one performed for analgesic cortical stimulation. No surgical complications were reported. The activation of the stimulator provided a reduction of 65%of the tinnitus impact, with a persistent effect on the right side. The feasibility of the cortical stimulation in symptomatic treatment of tinnitus was proven by this preparatory work. The middle- and long-term therapeuti

Changes in yield determinants and quality traits in wheat after 12 cycles of recurrent selection

The objective of this study was to test the genetic response to 12 cycles of a recurrent selection program for grain yield and related traits. During two seasons the 39 S-derived families (three/C0–C12 populations) were evaluated under conventional (CT) and non-tillage (NT) systems. Grain and biomass yield were determined. The grain number per square meter and harvest index were also estimated. Flour protein content, sodium dodecyl sulphate sedimentation, and lactic acid solvent retention capacity were considered as end-use quality predictive tests. High molecular weight glutenin subunits (HMW-GS) variation was also analyzed. A significant increase in grain yield per selection cycle, estimated in 3.25 g m−2 (1.3%) per year, was found under NT, but there was a not significant genetic progress under CT. The decrease in the percentage of protein in the most advanced selection cycles (11.0% vs. 9.7%) did not negatively affect its quality. HMW-GS variation analysis showed the erosion of extreme subunits related to gluten strength. After 24 years of recurrent selection, the grain yield was improved without affecting its industrial quality.Fil: Maich, Ricardo Héctor. Universidad Nacional de Córdoba.
