The evidence-based teaching: 4 courses ECTS pilot
La docencia universitaria, dentro del sistema europeo, plantea problemas a la hora de planificar las clases de teoría, las prácticas, los seminarios, las tutorías, los exámenes y las presentaciones de temas,
debido a la densidad de materia a impartir durante limitados periodos de tiempo y a la variabilidad de
metodologías a emplear para que toda la información llegue al alumno y al profesor mediante
mecanismos de autoaprendizaje y de feedback.
Normalmente, los alumnos realizan las actividades de una manera coordinada siempre dentro de las
clases teóricas, pero descoordinada en cuanto a orden temático en el resto de las actividades,
generándose la necesidad de volver a explicar o al menos recordar temas que se explicaron hace meses
cuando se abordan las clases prácticas y las presentaciones de temas.
Durante los 4 cursos (2006/7-2009/10) de experiencia piloto en la asignatura de Fisiología de la
titulación de Logopedia dentro del nuevo plan docente del Sistema Europeo que ya se implanta de
manera definitiva en el curso próximo, se han adquirido estrategias y destrezas por parte del alumno y
del profesor, para poder facilitar y mejorar tanto la tarea docente como la de aprendizaje. Ello ha
consistido en ir introduciendo innovaciones metodológicas idóneas para el buen funcionamiento del
sistema, que curso tras curso han ido favoreciendo la tarea complicada de coordinar las diferentes
actividades, mediante un diseño cronológico por bloques o módulos temáticos, siempre enfocado hacia
la optimización de la enseñanza basada en el aprendizaje del alumno como objetivo principal.University teaching, within the European system, creates problems in planning the lectures,
internships, seminars, tutorials, reviews and presentations of issues, because the density of matter to
provide for limited periods time and variability of methodologies used for all the information reach the
student and teacher through self-learning mechanisms and feedback.
Normally, students engaging in activities in a coordinated manner provided in the lectures, but
uncoordinated in terms of thematic order in the rest of the activities, generating the need to re-explain
or at least issues that were explained to remember months ago when addresses the practical sessions
and presentations of topics.
During the four courses (2006/7-2009/10) pilot experience in the subject of Physiology, Speech
Pathology degree under the new syllabus European System already implemented definitively in the
coming academic year, we have acquired strategies and skills by the student and teacher to facilitate
and improve the teaching task as learning. This has consisted in introducing innovations in
methodology suitable for the proper functioning of the system, course after course has been encouraging the complicated task of coordinating the various activities, with a design chronological thematic blocks or modules, always focused on the optimization of education based on student
learning as its main objective
Protective effects of fermented goat milk on genomic stability, oxidative stress and inflammatory signalling in testis during anaemia recovery
Oxidative stress is a harmful factor for male reproductive function, and a major cause of infertility. On the
other hand, fermented goat milk has positive effects on anemia recovery and mineral metabolism. This
study evaluated the effect of feeding rats with fermented milks during anaemia recovery on molecular
mechanisms linked to oxidative stress and inflammatory signalling in rats reproductive system. Forty male
Wistar rats were placed on a pre-experimental period of 40 days (control group, receiving normal-Fe diet and
Fe-deficient group, receiving low-Fe diet). Lately, rats were fed with fermented goat or cow milk-based diets
during 30 days. After feeding the fermented milks, Total antioxidant status (TAS) and non-esterified fatty
acids (NEFA) increased and 8-hydroxy-2’-deoxyguanosine (8-OHdG), 15-F2t-isoprostanes and thiobarbituric
acid reactive substances (TBARS) decreased in testis. DNA oxidative damage in testis germ cells was lower
with fermented goat milk. Fermented goat milk reduced IL-6 and TNF-α in control animals, increasing
INF-γ in control and anaemic rats. NRF2 and PGC-1α protein levels increased in testis after fermented goat
milk consumption in control and anaemic rats. Fermented goat milk also increased TAS and decreased
oxidative damage, protecting the main testis cell bioconstituents (lipids, proteins, DNA, prostaglandins)
from oxidative damage and reduced inflammatory activity, preventing injuries to testis germinal epithelium.
Fermented goat milk enhanced lipolysis, fatty acids degradation and immune response, attenuating
inflammatory signalling, representing a positive growth advantage for testicular cells.Jorge Moreno-Fernandez was supported by fellowship from the Ministry of Education, Culture and Sport (Spain)

Iron Deficiency and Neuroendocrine Regulators of Basal Metabolism, Body Composition and Energy Expenditure in Rats
Although dietary iron is a determinant of iron status in animals, body fat mass has
been reported to have an inverse association with iron status in human studies. The goal of
this study was to determine the relationship between Fe homeostasis, body composition, energy
expenditure and neuroendocrine regulators for severe Fe-deficiency anaemia. Forty male Wistar
albino rats recently weaned were divided at random into two groups: the control group was fed
the basal diet, AIN-93G diet (normal-Fe) and the anaemic group received a low-Fe diet for 40 days.
Neuroendocrine parameters that regulate basal metabolism and appetite (thyroid hormones, ghrelin,
glucose-dependent insulinotropic polypeptide (GIP), glucagon, insulin, adrenocorticotropic hormone
and corticosterone), body composition, respiratory volumes, energy expenditure, haematological
and biochemical were assessed. Total body fat was lower, whereas lean mass, free and total water
were higher in the anemic group. O2 consumption, CO2 production, energy expenditure (EE) and
respiratory quotient (RQ) were lower in the Fe-deficient animals. Triiodothyronine and thyroxine
hormones decreased, while thyroid-stimulating hormone increased in the anemic group. Circulating
levels of ghrelin were lower in the anemic group, while GIP, glucagon, insulin, corticosterone and
adrenocorticotropic hormone levels were higher. Fe-deficiency impairs weight gain in the rats,
with marked reductions in lean mass and body fat, indicating lower energy stores.This study was supported by the Excellence Project (P11-AGR-7648) from the Regional Government

Fermented Goat Milk Consumption Enhances Brain Molecular Functions during Iron Deficiency Anemia Recovery
Iron deficiency anemia (IDA) is one of the most prevalent nutritional deficiencies worldwide.
Iron plays critical roles in nervous system development and cognition. Despite the known detrimental
consequences of IDA on cognition, available studies do not provide molecular mechanisms elucidating
the role of iron in brain functions during iron deficiency and recovery with dairy components. In
this study, 100 male Wistar rats were placed on a pre-experimental period of 40 days and randomly
divided in two groups: a control group receiving a normal-Fe diet, (45 mg/kg), and an Fe-deficient
group receiving a low-Fe diet (5 mg/kg). At day 40, 10 rats per group were sacrificed to anemia
control, and 80 rats were divided into eight experimental groups fed with fermented goat or cow
milk-based diets, with normal Fe content or Fe overload (450 mg/kg) for 30 days. IDA decreased
most of the parameters related to brain molecular functions, namely dopamine, irisin, MAO-A,
oxytocin, -endorphin, and alpha-MSH, while it increased synaptophysin. These alterations result in
an impairment of brain molecular functions. In general, during anemia recovery, fermented goat
milk diet consumption increased dopamine, oxytocin, serotonin, synaptophysin, and alpha-MSH, and
decreased MAO-A and MAO-B, suggesting a potential neuroprotective effect in brain functions,
which could enhance brain molecular functions.This study was supported by the Excellence Research Project (P11-AGR-7648) from the Regional

A new insigh to bone turnover: role of ω-3 polyunsaturated fatty acids
Background. Evidence has shown that long-chain polyunsaturated fatty acids (LCPUFA), especially the ω-3 fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are beneficial for bone health and turnover. Objectives. This review summarizes findings from both in vivo and in vitro studies and the effects of LC PUFA on bone metabolism, as well as the relationship with the oxidative stress, the inflammatory process, and obesity. Results. Some studies in humans indicate that LCPUFA can increase bone formation, affect peak bone mass in adolescents, and reduce bone loss. However, the cellular mechanisms of action of the LCPUFA are complex and involve modulation of fatty acid metabolites such as prostaglandins, resolvins and protectins, several signaling pathways, cytokines, and growth factors, although in certain aspects there is still some controversy. LCPUFA affect receptor activator of nuclear factor κβ (RANK), a receptor found on the osteoclast, causing bone resorption, which controls osteoclast formation. Conclusions. Since fatty acids are an endogenous source of reactive oxygen species, free radicals alter the process of bone turnover; however, although there are clinical evidences linking bone metabolism and dietary lipids, more clinical trials are necessary to prove whether ω-3 PUFA supplementation plays a major role in bone health
A didactic activity of support to foment the acquisition of capabilities of the student in the study of the Physiopathology
En el nuevo entorno de aprendizaje del Espacio Europeo de Educación Superior (EEES), tiene gran
importancia fomentar la adquisición de competencias transversales en el alumno: trabajo en grupo,
saber obtener información de forma efectiva a partir de libros, revistas y búsquedas bibliográficas,
saber elaborar presentaciones audiovisuales, capacidad de comunicación oral y escrita.
La Fisiopatología es una asignatura troncal anual con 6 créditos teóricos ECTS, de tercer curso de la
Licenciatura de Farmacia de la Universidad Granada. Desde la puesta en marcha del Plan Piloto de
implantación del EEES (curso 2007-08), se está desarrollando una técnica didáctica para fomentar el
rendimiento del alumno en esta asignatura. Al comienzo de curso el profesor facilita al alumnado una
relación de temas del programa de la asignatura que con carácter voluntario seleccionan en grupos
reducidos (2-4 alumnos), para su preparación y posterior exposición en el aula. El profesor facilita el
guión y la bibliografía del tema a desarrollar. Bajo su tutorización los alumnos elaboran el tema y la
presentación en PowerPoint, que tras revisión y aprobación por el profesor es expuesto al conjunto de
la clase. Previo a la exposición, el material docente se descarga en la plataforma SWAD de apoyo a la
docencia. Cada trabajo es evaluado en sus contenidos, exposición y defensa representando un 15% de
la calificación final de la asignatura.
La valoración global de esta actividad, desarrollada a lo largo de tres cursos académicos, ha sido totalmente positiva en su aceptación, participación y calidad de los temas desarrollados.In the new environment of learning of the European Space for Higher Education (ESHE), it has a great
importance to foment the acquisition of transverse capabilities in the students: teamwork, to be able to
obtain information of effective form from books, scientific journals and bibliographical searches, to elaborate audio-visual presentations, capacity of oral and written communication.Physiopathology is a main annual subject with 6 theoretical ECTS credits, of the third course of the
Pharmacy B. Degree of the University Granada. From the beginning in March of the Pilot Plan of
introduction of the ESHE (academic course 2007-08), a didactic skill is being developed to efficiency
of the student in this subject. At the beginning of the course the professor facilitates to the students a
relation of topics from the program of the subject that with voluntary character they select in small
groups (2-4 students), for preparation and later presentation in the classroom. The professor supplies
the script and the bibliography of the topic to develop. Under its assistance, the students elaborate the
topic and the presentation in PowerPoint, which after review and approval for the professor is
displayed to the rest of the students. Before the exhibition, the educational material it is uploaded in
the platform WSST (Web Service to Support Teaching) of the University of Granada. Every work is
evaluated taking into account the contents, presentation and defense, representing 15 % of the final
qualification of the subject.
The global evaluation of this activity, developed along three academic courses, has been totally positive in its acceptance, participation and quality of the developed topics
Lockdown, Emotional Intelligence, Academic Engagement and Burnout in Pharmacy Students during the Quarantine
The recent appearance and rapid spread of the new SARS-CoV-2 coronavirus meant
taking unprecedented measures to control the pandemic, which in Spain forced a state of alarm
and a very strict confinement, leading the university system to become virtual online teaching.
Taking into account the emotional deficiencies originated during the pandemic, among the most
powerful tools to achieve engagement along with the identification, control and management of
emotions is emotional intelligence (EI). The present study aims to establish the effect of the current
confinement on the teaching-learning process and academic performance and the impact of the
application of EI on university students. In total, 47 volunteers of the second course of the Degree
in Pharmacy of the University of Granada (Spain) took part in this experience. Two temporary
periods were established: at the beginning of the confinement period and after teaching several
concepts of emotional intelligence online for two months. The Maslach Burnout Inventory-Student
Survey Inventory (MBI-SS) and the Spanish version of Utrech Work Engagement Scale-Students
(UWES-S) were used to evaluate the intervention. In total, 63.5% of the students presented academic
burnout during the confinement before the intervention. After the EI workshops and seminars,
only 31.1% presented academic burnout. Before the intervention with the emotional intelligence
workshops, 44.6% experienced exhaustion, 41.7% cynicism and 60.3% felt it was ineffective in their
academic performance. After the emotional intelligence workshops and seminars, 29.1% experienced
exhaustion, 30.1% cynicism and 28.8% felt it was ineffective. The scores achieved after the study of EI
in physiology classes led to better levels in all the variables studied. Students managed their adaptive
processes more adequately and regulated their emotions better, as they felt less academic burnout
and more engaged in their academic activities at the end of the study of EI through physiolog
Influence of cow or goat milk consumption on antioxidant defence and lipid peroxidation during chronic iron repletion
Despite Fe deficiency and overload having been widely studied, no studies are available about the influence of milk consumption on antioxidant
defence and lipid peroxidation during the course of these highly prevalent cases. The objective of the present study was to assess
the influence of cow or goat milk-based diets, either with normal or Fe-overload, on antioxidant defence and lipid peroxidation in the liver,
brain and erythrocytes of control and anaemic rats after chronic Fe repletion. Weanling male rats were randomly divided into two groups: a
control group receiving a normal-Fe diet (45 mg/kg) and an anaemic group receiving a low-Fe diet (5 mg/kg) for 40 d. Control and anaemic
rats were fed goat or cow milk-based diets, either with normal Fe or Fe-overload (450 mg/kg), for 30 or 50 d. Fe-deficiency anaemia did not
have any effect on antioxidant enzymes or lipid peroxidation in the organs studied. During chronic Fe repletion, superoxide dismutase
(SOD) activity was higher in the group of animals fed the cow milk diet compared with the group consuming goat milk. The slight modification
of catalase and glutathione peroxidise activities in animals fed the cow milk-based diet reveals that these enzymes are unable to
neutralise and scavenge the high generation of free radicals produced. The animals fed the cow milk diet showed higher rates of lipid
peroxidation compared with those receiving the goat milk diet, which directly correlated with the increase in SOD activity. It was concluded
that goat milk has positive effects on antioxidant defence, even in a situation of Fe overload, limiting lipid peroxidatio
The university stage does not favor the healthy life style in women students from Granada
Objetivo: La etapa universitaria conlleva una serie de
cambios emocionales, fisiológicos y ambientales que van
a determinar unas costumbres y hábitos de riesgoque en
muchos casos serán mantenidos a lo largo de la vida y repercutirán
en su estado de salud. El objetivo del presente
estudio es analizar el estilo de vida (consumo de alcohol,
tabaco y niveles de actividad física) de mujeres estudiantes
de la Universidad de Granada.
Metodología: Se trata de un estudio transversal/descriptivo
y analítico en el que han participado 55 estudiantes
de dos grupos de edad (18-24 y 25-31años). Se
aplicó un cuestionario de estilo de vida evaluando el tipo
de alcohol y frecuencia de consumo, cantidad de cigarrillos
consumidos diariamente y niveles de actividad física
(sedentaria, ligera, moderada e intensa).
Resultados: El consumo de alcohol es mayor en el grupo
de mayor edad, y con preferencia beben cerveza/vino,
sin embargo el grupo más joven muestra un patrón de
consumo centrado en los fines de semana siendo las bebidas
destiladas las consumidas preferentemente. Una
tercera parte de la población fuma con un incremento en
el número de cigarros conforme aumenta la edad. Existe
una correlación positiva entre tabaco y alcohol. El 88.9%
del grupo de menor edad y el 52.7% del grupo de mayor
edad tienen una actividad física sedentaria-ligera.
Conclusión: Se sugiere la necesidad de concienciar a
la población femenina universitaria sobre los beneficios
del abandono del consumo de alcohol y tabaco y la práctica
regular de ejercicio físico. Además, sería aconsejable
desarrollar protocolos de intervención educativa en
el ámbito universitario potenciando los hábitos de vida
saludables.Objective: The university stage involves a series of
emotional, physiological and environmental changes that
will determine consumer patterns that, in many cases,
will be maintained and will affect their health. The aim
of this study is to analyze the lifestyle (alcohol and tobacco
consumption, and levels of physical activity) of female
students at the University of Granada. Several authors
have noted that the student population is particularly
vulnerable to develop risk customs and habits, since the
period of university studies is often the time when students
take first responsibility for determining their own
styles and customs, which in many cases will be maintained
throughout its entire life.
Methodology: This is a cross / descriptive and analytical
study in which 55 students participated in two age
groups (18-24 and 25-31 years). A lifestyle-questionnaire
was applied to evaluate the type and frequency of alcohol
consumption, number of cigarettes smoked daily and
physical activity levels (sedentary, light, moderate and
severe).
Results: Alcohol consumption is higher in the older
group, and preferably drinks beer and wine; however
the younger group shows a pattern of consumption centered
on the weekends being preferably consumed distilled
beverages. A third of the population smokes with
an increase in the number of cigarettes as age increases.
There is a positive correlation between snuff and alcohol.
A direct positive correlation between tobacco and
alcohol was observed. The 88.9% of lesser age group
and 52.7% of higher age group show a sedentary-low
physical activity.
Conclusion: The need to sensitize the college female
population on the benefits of no-consumption of alcohol
and snuff, and regular physical exercise is suggested. It
would also be advisable to develop protocols of educational
intervention in universities promoting healthy living
habits
Effect of fermented goat milk on body composition, basal metabolism, and food intake control in rats
Introducción: es conocido que la dieta juega un papel clave en la composición corporal y afecta al balance energético; sin embargo, la información
es limitada acerca de la influencia de alimentos y nutrientes específicos como es el caso de los productos lácteos, un grupo básico de
alimentos y una importante fuente de nutrientes en la dieta.
Objetivos: evaluar la influencia del consumo de leche fermentada de cabra o vaca sobre la composición corporal y la regulación del apetito en
animales adultos.
Material y métodos: se han utilizado 20 ratas Wistar macho adultas, alimentadas durante 30 días con dietas basadas en leche fermentada de
vaca o de cabra. Se analizaron la evolución de la composición corporal y las concentraciones plasmáticas de adipoquinas (leptina y adiponectina),
hormonas reguladoras del metabolismo intermediario (grelina, insulina, hormona estimulante de la glándula tiroides, triyodotironina y tiroxina) y
ácidos grasos no esterificados (AGNE).
Resultados: el peso y el porcentaje de grasa corporal fueron menores (p < 0,001) y la masa magra fue mayor (p < 0,01) en los animales
alimentados con la dieta basada en leche fermentada de cabra. No se registraron diferencias entre dietas para las concentraciones plasmáticas
de hormonas tiroideas y de insulina. Las concentraciones plasmáticas de grelina y adiponectina disminuyeron (p < 0,001), y las de leptina y
AGNE aumentaron (p < 0,001) con la dieta basada en leche fermentada de cabra.
Conclusión: el consumo habitual de leche fermentada de cabra disminuye la adiposidad y el peso corporal en las ratas adultas al incrementar
el gasto energético, la lipólisis y la sensación de saciedad.Introduction and objective: it is known that diet plays a key role in body composition and affects energy balance. However, scarce information is
available in the scientific literature about the influence of food and specific nutrients such us dairy products, a basic food group and an important
source of nutrients in the diet. The objective of this work was to evaluate the influence of fermented dairy products (goat or cow milk) on body
composition and appetite regulation in adult animals.
Material and methods: twenty adult male Wistar albino rats were fed fermented goat or cow milk-based diets for 30 days. The evolution of
body composition and plasma concentrations of adipokines (leptine and adiponectine), intermediary metabolism regulating hormones (ghrelin,
insulin, thyroid stimulating hormone, triyodotironine, thyroxine), and non-esterified fatty acid (NEFA) were analyzed.
Results: body weight and body fat percentage were lower (p < 0.001) in rats fed fermented goat milk versus those fed fermented cow milk,
whereas lean mass percentage was higher (p < 0.01). Plasma thyroid hormone and insulin concentrations did not show significant differences
between diets. The fermented goat milk-based diet decreased ghrelin and adiponectin levels (p < 0.001), and increased leptine and NEFA
concentrations (p < 0.001).
Conclusion: fermented goat milk consumption decreases adiposity and body weight in adult rats by increasing energy expenditure, lipolysis,
and satiety sensation.Este trabajo ha sido financiado por la Junta de Andalucía en el marco del Proyecto de Excelencia P11-AGR-7648
