Guía práctica de salud infantil.

Este trabajo se ha utilizado como refuerzo del programa de Ciencias de sexto de EGB en el Colegio de Beteta (Cuenca), programa basado fundamentalmente en Fisiología humana. Su objetivo es por un lado informar y por otro despertar actitudes en el alumno. Utiliza el comic como vehículo de información para llegar al niño e intenta ser una guía fácil que sirva para cuidar la higiene personal mediante unos pocos ejercicios diarios, semanales o mensuales. Al final figuran unos registros para que el propio alumno aprecie sus progresos a modo de autoevaluación, con el objeto de que se responsabilice de su higiene. También se adjuntan modelos de registros de evaluación para el maestro.

Human biology and health studies.

Proporciona a los estudiantes los temas requeridos para el primer año del curso GCSE, especialidad biología. Es una edición revisada para el nuevo AQA GCSE en Fisiología humana y estudios de la salud.

Programación de las ciencias naturales de 3õ de bachillerato : una experiencia realizada por el seminario del I.N.B. 'Calderón de la Barca' de Madrid.

La asignatura de Ciencias Naturales de 3õ BUP optativa con cuatro horas lectivas sigue un programa que consideramos, en cierto modo, incoherente para el nivel de los alumnos. Se mezclan en el tres tipos de materias dispares: Anatomía, Fisiología Humana, Anatomía y Fisiología de las plantas y algunos temas incoherentes de Geología. Este programa es un ejemplo que plantea la necesidad de una reordenación de los programas de esta materia. En conjunto uniformes, con una separación de las distintas materias de esta asignatura en los distintos cursos. Sería útil mantener la asignatura en los tres cursos con tres horas semanales; Un primer curso de zoología y botánica y microbiología descriptiva; un segundo, de geología básica, ecología y evolución paleontológica; un tercero, de biología general y anatomía y fisiología humanas. El temario oficial lo dividimos en cinco partes para coincidir con las evaluaciones. 1. Química e Histología animal. 2. Funciones de nutrición. 3. Funciones de relación y reproducción. 4. Geología. 5. Botánica.

Análisis y desarrollo de un sistema de automatización de bajo coste para ayuda a la docencia universitaria.

Desarrollar e implantar un programa de gestión docente mediante ordenador y evaluar su funcionamiento. Dos grupos docentes de la Facultad de Medicina, en los últimos meses del curso académico 81-82. El programa de gestión se realizó en varias fases: análisis de la estructuración docente de la facultad; análisis de las necesidades de material; evaluación del coste y rendimiento del programa y desarrollo y aplicación práctica. La utilización del programa ha agilizado las tareas de elaboración de convocatorias y centros de asistencia. Las mayores ventajas se han observado en el proceso de evaluación, en cuanto a mejora del diseño de las pruebas, mayor rapidez entre la fecha de examen y la comunicación de resultados, mejora del proceso de corrección, siendo plenamente aceptado por el profesorado y el alumnado.

Strong iron demand during hypoxia-induced erythropoiesis is associated with down-regulation of iron-related proteins and myoglobin in human skeletal muscle

[EN] Iron is essential for oxygen transport because it is incorporated in the heme of the oxygen-binding proteins hemoglobin and myoglobin. An interaction between iron homeostasis and oxygen regulation is further suggested during hypoxia, in which hemoglobin and myoglobin syntheses have been reported to increase. This study gives new insights into the changes in iron content and iron-oxygen interactions during enhanced erythropoiesis by simultaneously analyzing blood and muscle samples in humans exposed to 7 to 9 days of high altitude hypoxia (HA). HA up-regulates iron acquisition by erythroid cells, mobilizes body iron, and increases hemoglobin concentration. However, contrary to our hypothesis that muscle iron proteins and myoglobin would also be up-regulated during HA, this study shows that HA lowers myoglobin expression by 35% and down-regulates iron-related proteins in skeletal muscle, as evidenced by decreases in L-ferritin (43%), transferrin receptor (TfR; 50%), and total iron content (37%). This parallel decrease in L-ferritin and TfR in HA occurs independently of increased hypoxia-inducible factor 1 (HIF-1) mRNA levels and unchanged binding activity of iron regulatory proteins, but concurrently with increased ferroportin mRNA levels, suggesting enhanced iron export. Thus, in HA, the elevated iron requirement associated with enhanced erythropoiesis presumably elicits iron mobilization and myoglobin down-modulation, suggesting an altered muscle oxygen homeostasis.

Gender dimorphism in skeletal muscle leptin receptors, serum leptin and insulin sensitivity

[EN] To determine if there is a gender dimorphism in the expression of leptin receptors (OB-R170, OB-R128 and OB-R98) and the protein suppressor of cytokine signaling 3 (SOCS3) in human skeletal muscle, the protein expression of OB-R, perilipin A, SOCS3 and alpha-tubulin was assessed by Western blot in muscle biopsies obtained from the m. vastus lateralis in thirty-four men (age = 27.1+/-6.8 yr) and thirty-three women (age = 26.7+/-6.7 yr). Basal serum insulin concentration and HOMA were similar in both genders. Serum leptin concentration was 3.4 times higher in women compared to men (P<0.05) and this difference remained significant after accounting for the differences in percentage of body fat or soluble leptin receptor. OB-R protein was 41% (OB-R170, P<0.05) and 163% (OB-R128, P<0.05) greater in women than men. There was no relationship between OB-R expression and the serum concentrations of leptin or 17beta-estradiol. In men, muscle OB-R128 protein was inversely related to serum free testosterone. In women, OB-R98 and OB-R128 were inversely related to total serum testosterone concentration, and OB-R128 to serum free testosterone concentration. SOCS3 protein expression was similar in men and women and was not related to OB-R. In women, there was an inverse relationship between the logarithm of free testosterone and SCOS3 protein content in skeletal muscle (r = -0.46, P<0.05). In summary, there is a gender dimorphism in skeletal muscle leptin receptors expression, which can be partly explained by the influence of testosterone. SOCS3 expression in skeletal muscle is not up-regulated in women, despite very high serum leptin concentrations compared to men. The circulating form of the leptin receptor can not be used as a surrogate measure of the amount of leptin receptors expressed in skeletal muscles.

Exercise and bone mass in adults

[EN] There is a substantial body of evidence indicating that exercise prior to the pubertal growth spurt stimulates bone growth and skeletal muscle hypertrophy to a greater degree than observed during growth in non-physically active children. Bone mass can be increased by some exercise programmes in adults and the elderly, and attenuate the losses in bone mass associated with aging. This review provides an overview of cross-sectional and longitudinal studies performed to date involving training and bone measurements. Cross-sectional studies show in general that exercise modalities requiring high forces and/or generating high impacts have the greatest osteogenic potential. Several training methods have been used to improve bone mineral density (BMD) and content in prospective studies. Not all exercise modalities have shown positive effects on bone mass. For example, unloaded exercise such as swimming has no impact on bone mass, while walking or running has limited positive effects.

Androgen receptor gene polymorphisms lean mass and performance in young men

[EN] The exon-1 of the androgen receptor (AR) gene contains two repeat length polymorphisms which modify either the amount of AR protein inside the cell (GGN(n), polyglycine) or its transcriptional activity (CAG(n), polyglutamine). Shorter CAG and/or GGN repeats provide stronger androgen signalling and vice versa. To test the hypothesis that CAG and GGN repeat AR polymorphisms affect muscle mass and various variables of muscular strength phenotype traits, the length of CAG and GGN repeats was determined by PCR and fragment analysis and confirmed by DNA sequencing of selected samples in 282 men (28.6 +/- 7.6 years). Individuals were grouped as CAG short (CAG(S)) if harbouring repeat lengths of 21. GGN was considered short (GGN(S)) or long (GGN(L)) if GGN 23, respectively. No significant differences in lean body mass or fitness were observed between the CAG(S) and CAG(L) groups, or between GGN(S) and GGN(L) groups, but a trend for a correlation was found for the GGN repeat and lean mass of the extremities (r=-0.11, p=0.06). In summary, the lengths of CAG and GGN repeat of the AR gene do not appear to influence lean mass or fitness in young men.
