Eating Beef Liver Can Improve Long-Term Memory

Escrito por

64817 A new study in rats has shown that consuming choline, a vitamin B group nutrient found in foodstuffs like eggs and chicken or beef liver, soy and wheat germ, helps improve long-term memory and attention-holding capacity.

The study, conducted by scientists at the University of Granada (Spain), Simon Bolivar University, (Venezuela) and the University of York (United Kingdom), has revealed that choline is directly involved in attention and memory processes and helps modulate them.

Researchers studied the effects of dietary supplements of choline in rats in two experiments aimed at analysing the influence of vitamin B intake on memory and attention processes during gestation and in adult specimens.

In the first experiment, scientists administered choline to rats during the third term of gestation in order to determine the effect of prenatal choline on the memory processes of their offspring.

Three groups of pregnant rats were fed choline-rich, standard or choline-deficient diets.

When their offspring had reached adult age, a sample of 30 was selected: 10 were female offspring of dams fed a choline-supplement, 10 had followed a choline-deficient diet and the other 10, a standard diet, acting as a control group.

This sample of adult offspring underwent an experiment to measure their memory retention: 24 hours after being shown an object all the offspring (whether in the choline-supplement group or not) remembered it and it was familiar to them.

However, after 48 hours, the rats of dams fed a prenatal choline-rich diet recognized the object better than those in the standard diet group, while the choline-deficient group could not recognize it.

Thus, the scientists concluded that prenatal choline intake improves long-term memory in the resulting offspring once they reach adulthood.

In the second experiment, the researchers measured changes in attention that occurred in adult rats fed a choline supplement for 12 weeks, versus those with no choline intake.

They found that the rats which had ingested choline maintained better attention that the others when presented with a familiar stimulus.

The control group, fed a standard diet, showed the normal learning delay when this familiar stimulus acquired a new meaning.

However, the choline-rich intake rats showed a fall in attention to the familiar stimulus, rapidly learning its new meaning.

The study is published in the journal Nutritional Neuroscience and Behavioural Brain Research.

Exercising During Pregnancy Reduces the Risk of High Birth Weight Newborns and of Caesarean Delivery, Study Suggests

Escrito por

65951 Researchers have found that moderate-intensity exercise three times a week during the second and third trimesters of pregnancy halves the risk of having a newborn baby with macrosomia (weighing over 4 kilos).

Taking moderate-intensity exercise three times a week during the second and third trimester of pregnancy halves the risk of having a high birth weight newborn (babies with macrosomia, that is, weighing over 4 kilos) and, therefore, the risk of needing a caesarean delivery.
These findings come from research led by Rubén Barakat of the Polytechnic University of Madrid, Alejandro Lucía of the European University of Madrid, and Jonatan Ruiz of the University of Granada. Together with Sports Science graduates, they ran a series of programmed training sessions for a sample of 510 sedentary pregnant women. The results of their study have been published in the British Journal of Sports Medicine.
The researchers contacted a total of 780 Spanish pregnant women attending two primary health care centres in Leganés (Madrid). Finally, 510 gave their consent to participate in the study. They all recognized they were sedentary — that is, that they exercised for less than 20 minutes on fewer than 3 days a week.
55 minutes exercise
The intervention group followed a training program that consisted of 55 minute sessions of aerobic, muscle strength and flexibility exercises on three days a week from weeks 10-12 to weeks 38-39 of pregnancy, while the control group received standard recommendations and care.
The results showed the training sessions did not reduce the appearance of gestational diabetes mellitus but did diminish the incidence of two major associated risks: macrosomia (down by 58%) and caesarean delivery (which fell by 34%).
These findings «reinforce the need to encourage more supervised exercise interventions during pregnancy to combat the negative effects of gestational diabetes mellitus,» says Jonatan Ruiz, researcher in the University of Granada Department of Physical and Sports Education and corresponding author of the study.

Organizan primer Curso Nacional de Música Sacra de España

Escrito por

Hasta el 21 de julio la Diócesis de Guadix (España), es sede del primer Curso Nacional de Música Sacra, que reúne a integrantes de coros y a todos los que prestan este servicio a la Iglesia.

El curso ha sido organizado por el Cabildo de la Catedral de Guadix y la Federación Española de Pueri Cantores en colaboración con la Universidad de Granada.

El director del Curso Nacional de Música Sacra, el diácono Francisco Javier jiménez Martínez, ha declarado a ACI Prensa que se trata de «un curso dirigido a integrantes de coros, organistas, cantores… A todos los que prestan este servicio a la Iglesia a través de la música».

Según sus organizadores, este primer congreso que se inició el pasado 15 de julio, se enmarca en el 50º aniversario de la aprobación de la Constitución sobre la Sagrada Liturgia, Sacrosanctum Concilium, del Concilio Vaticano II. Además tiene lugar al final del Año de la Fe que convocó Benedicto XVI y que demuestra que la Iglesia sigue necesitando expresar la fe mediante la belleza en nuestras celebraciones litúrgicas. La música es, quizás, el mejor modo de contemplar la belleza que procede de Dios.

Jiménez Martínez cuenta que son días «de formación musical y litúrgica a través de clases magistrales, talleres y visitas culturales. Participan unos 30 alumnos de toda España que ya trabajan en ámbitos relacionados con la música sacra».

Y es que según Jiménez «la música sacra es un servicio a la Iglesia, porque es un lugar teológico, un lugar de encuentro con Dios que expresa junto con la palabra aquello que es inefable».

Los participantes al curso también asistirán a un ciclo de conciertos de música sacra en la Catedral de Granada.

Vitamin B Can Improve Your Memory

Escrito por

64817 If you’re preparing for a big test, you might consider increasing your vitamin B intake, as it has recently been connected to improved memory and attention span.

An experimental study conducted by the University of Granada in Spain, Simón Bolívar University in Venezuela, and University of York in the U.K. has recently revealed that consuming a vitamin B group called choline can modulate your attention span and memory processes.

To test their hypothesis, researchers from these universities studied the effects of choline dietary supplements in rats in two experiments. Both experiments produced evidence in favor of the researchers’ initial claims.

One experiment determined that prenatal choline improves the memory processes of the rats’ offspring once they reach adult age. Meanwhile, the second experiment tested choline’s affects on adult rats and determined that the rats that had ingested choline maintained better attention than rats who had not given a similar stimulus.

Other studies have also suggested a connection between choline and brain health, claiming that a diet rich in choline could also prevent brain changes associated with dementia and Alzheimers.

So far, however, researchers have only tested their findings in rats. Rhoda Au, a senior researcher at the Boston University School of Medicine, hopes that more studies in humans will occur to back up the current evidence, including studies that follow changes in people’s cognitive abilities over time.

Regardless, experts recommend 550 milligrams of choline per day for men and 425 milligrams per day for women. Choline-rich foods include eggs, chicken, beef liver, soy, and wheat germ. For a quick way to improve the choline-content of your next lunch, try making this Grilled Chicken and Egg Potato Salad.

A un paso de implantar los primeros huesos artificiales creados a través de células madre

Escrito por

66186 Las células madre están cambiando la forma de concebir el mundo. Con un asentamiento más que aplaudido en el ámbito científico, vuelven a dar nuevos pasos para la lucha contra enfermedades. Esta vez su puesta en marcha estuvo relacionada con la rehabilitación de lesiones óseas.

Y es que tras años de investigación, la ciencia desarrolla los primeros huesos artificiales por parte de un grupo de expertos españoles. De esta manera, lograron crear huesos artificiales a partir de células madre y carbón activado. Se trata de un nuevo biomaterial que permite generar tejido óseo o huesos artificiales a partir de células madre procedentes de cordón umbilical que son previamente diferenciadas sobre un soporte de tela de carbón activado.

El hallazgo, que fue patentado a través de la Oficina de Transferencia de Resultados de Investigación de la Universidad de Granada, podría servir para la fabricación de medicamentos destinados a la reparación de lesiones óseas u osteocondrales, tumorales o traumáticas. Los expertos señalan que también podrían permitir la sustitución del cartílago en las extremidades óseas que lo hayan perdido.

La razón por la que escogieron el carbón activado como medio de experimentación es que este tipo de material cuenta con «una superficie específica, es decir, que no es real, es de 2.000 metros cuadrados por gramo, de manera que permite el anclaje de infinito número de células, y sus propiedades mecánicas logran que se produzca una diferenciación sin añadir factores extraños».

En la actualidad no existe ningún tipo de producto alternativo en el mercado, ni tampoco descrito en la bibliografía científica. Sí existen antecedentes de desarrollo de materiales que «cumplen la función básica de estimular la diferenciación celular, pero nunca antes se había logrado producir en vivo un material biológicamente complejo y semejante al tejido óseo».

De momento, la investigación ha sido desarrollada exclusivamente en laboratorio, donde se ha obtenido el hueso artificial, pero prometen llegar a implantarlo en modelos de experimentación animal, ya sean ratones o conejos, para comprobar si es capaz de regenerar el hueso en ellos y reparar así una lesión ósea, fase que los investigadores pretenden iniciar el próximo septiembre.

La investigación fue llevada a cabo por el Centro de Investigación Biomédica de la Universidad de Granada, las facultades de Ciencias de Granada y Jaén y el Instituto de Parasitología y Biomedicina López Neyra (CSIC).
