Diferencias en la actividad física y la condición física entre los escolares de secundaria de dos programas curriculares oficiales de bogotá, colombia

Abstract: During the past five decades there has been an increased in the prevalence of obesity and over weight, also in physical inactivity and /or low cardiorespiratory fitness within the population in school age from diverse regions of the planet, including Bogota-Colombia. The general objective of this study was to compare the physical condition and the levels of physical activity from students who belonged to two curriculum programs of the Public Schools Network from Bogota, one of which includes two sessions per week, each session of 90 minutes of physical activity. We developed a research of unlike cross-sectional groups. There were 178 children evaluated from the regular curriculum and 170 kids belonging to the program 40 x 40. The physical condition was evaluated applying the protocol of high priority from the ALPHA -Fitness test Battery. The weight, height, body mass index, the waist circumference, the standing long jump, the handgrip in both hands and the motor fitness 20 meter shuttle run test were developed under standardized conditions. The Global School Health Survey (GSHS) was used to evaluate the levels of AF. No significant statistical differences were founded between P-40x40 and the regular curriculum regarding: weight, height, the body mass index, the waist circumference, the handgrip in both hands and the explosive strength in lower limbs. Nevertheless the cardiorespiratory fitness was significantly lower within de P-40x40. In conclusion the participation in the curricular program 40 x 40 was not associated with better levels of physical condition.

The effect of anchor voices and visible speech in training in the GRABS scale of perceptual evaluation of dysphonia

Abstract: Introduction Perceptual evaluation of voice quality remains a key standard for judgement of vocal impairment. The GRABS method has become a commonly used scale for rating severity of dysphonia, but it has no published, standardised protocol to follow. Training is important for reaching good interrater agreement for its parameters; however, the references most often cited for the GRABS provide no guidelines for clinical administration, speech material or rating calibration. This study investigated the effect of anchors (standard reference voices) and visible speech (narrow band spectrogram) in training non-expert professionals in the GRABS method. Material and methods Four inexperienced listeners evaluated 107 recorded pathological voices using the GRABS scale in 2 separate sessions; at first, without a visible spectrogram and then, 6 months later, with anchors and a narrow band spectrogram as additional information. Results The results show that anchors and visible speech helped to improve the reliability of G , B , A and S parameters. Interrater agreement according to k statistics was significantly stronger with the addition of spectrographic information for rating breathiness and strain. Discussion This study found that non-expert listeners showed significant improvement after training with external anchors (standard reference voices) and a narrow band spectrogram.

Immunomodulatory Fungi: An Alternative for the Treatment of Cancer

Abstract: The present study aims to determine the role of immunomodulatory fungi for the treatment of cancer as an alternative way. Mushrooms have been part of human culture for thousands of years, many cultures especially from the East, recognized that the extracts of certain fungi could have great health benefits. Recent research has focused on identifying compounds that can modulate, positively or negatively, the biological responses of immune cells. These compounds stimulate immunity, and not only for the treatment of cancer, but also for immunodeficiency diseases; for drug-induced generalized immune suppression; for therapy combined with antibiotics and as adjuvant for vaccines. The medicinal mushrooms are considered as immunomodulators, they are able to regulate the immune system. A diverse collection of bioactive polysaccharides, glycoproteins, glycopeptides, and proteoglycans have an effect on the proliferation and differentiation of immune cells and cytokines. Different purified polysaccharides have had clinical use in Japan, China, and Korea for many years, without reports of negative effects in the short term or in the long term. Different studies have shown that the application of polysaccharide extracts can have a cancer prevention effect and a restriction of tumor metastasis; they have also been used to treat microbial and viral infections, cardiovascular diseases and diabetes.
