Nutritional ergogenic aid use in male college students

The perceived need of nutritional ergogenic aids among college students produces concern regarding the safety and efficacy of such aids. The purpose of this research is to evaluate the rationale and use of nutritional ergogenic aids in male college students ages 18-25. Students participated in an anonymous survey assessing nutritional ergogenic supplementation and rationale behind use. There was no significant difference in supplement use between competitive and non-competitive athletes (p=0.708). However, a significant difference in nutritional ergogenic aid use between heavy and light exercisers was noted, with heavy exercisers more likely to use supplements than light exercisers (p=0.041). The primary rationale behind supplement use was to provide energy (22%), enhance recovery (19.6%), and build muscle (19.4%). Participants were most likely to obtain information on supplements from friends (79%) or the internet (79%) therefore; universities should provide education on nutritional ergogenic aids by providing reputable sources of these products

Mindfulness in Measurement: Reconsidering the Measurable in Mindfulness Practice

Can an organic partnership of qualitative and quantitative data confirm the value of mindfulness practice as an assignment in undergraduate education? Working from qualitative evidence suggesting the existence of potentially measurable mindfulness effects expressed in ruler measures, a previous study calibrated a mathematically invariant scale of mindfulness practice effects with substantively and statistically significant differences in the measures before and after the assignment. Current efforts replicated these results. The quantitative model is described in measurement terms defined at an introductory level. Detailed figures and appendices are provided, and a program of future research is proposed

Toward Increased Professionalism in Teaching English as a Second or Other Language through Pre-service Trainee Teacher Mentoring in the United Arab Emirates

For a variety of reasons, both historical and sociological, the feasibility – as well as the very desirability – of mainstream teaching securing the status of a profession (in the sense of established professions such as law, medicine, architecture, and engineering) has long been questioned (e.g., Burbules and Densmore, 1991). If this is the case as regard regular, mainstream education, what then is the situation in relation to the subfield of teaching that is teaching English as a second or other language (TESOL)? Sadly, few if any would likely doubt that the field has so far failed to achieve the status of a recognized profession. There are numerous causes of this failure, though some especially salient reasons – less than stellar public perceptions of the fields of English as a second language/English as a foreign language, employment standards of the private sector, that is, the (in) famous English language teaching industry, the initial training and qualifications of those in the field, and discriminatory practices – will be highlighted in the following discussion. In addition, the second half of this paper draws and reflects on a trainee teacher mentoring scheme at a federally-sponsored institution of higher education in the United Arab Emirates – now sadly discontinued – which the author participated in for 3 years between 2011 and 2015, and which, it is argued, exemplified programs which can go some not inconsiderable way toward combatting a number of the obstacles currently preventing the field of TESOL achieving the status of a legitimate profession

An evidence map of the effect of Tai Chi on health outcomes.

BackgroundThis evidence map describes the volume and focus of Tai Chi research reporting health outcomes. Originally developed as a martial art, Tai Chi is typically taught as a series of slow, low-impact movements that integrate the breath, mind, and physical activity to achieve greater awareness and a sense of well-being.MethodsThe evidence map is based on a systematic review of systematic reviews. We searched 11 electronic databases from inception to February 2014, screened reviews of reviews, and consulted with topic experts. We used a bubble plot to graphically display clinical topics, literature size, number of reviews, and a broad estimate of effectiveness.ResultsThe map is based on 107 systematic reviews. Two thirds of the reviews were published in the last five years. The topics with the largest number of published randomized controlled trials (RCTs) were general health benefits (51 RCTs), psychological well-being (37 RCTs), interventions for older adults (31 RCTs), balance (27 RCTs), hypertension (18 RCTs), fall prevention (15 RCTs), and cognitive performance (11 RCTs). The map identified a number of areas with evidence of a potentially positive treatment effect on patient outcomes, including Tai Chi for hypertension, fall prevention outside of institutions, cognitive performance, osteoarthritis, depression, chronic obstructive pulmonary disease, pain, balance confidence, and muscle strength. However, identified reviews cautioned that firm conclusions cannot be drawn due to methodological limitations in the original studies and/or an insufficient number of existing research studies.ConclusionsTai Chi has been applied in diverse clinical areas, and for a number of these, systematic reviews have indicated promising results. The evidence map provides a visual overview of Tai Chi research volume and content.Systematic review registrationPROSPERO CRD42014009907

Apoptosis in the Medaka Embryo in the Early Developmental Stage

Apoptosis is an important event of the development of various organs. In this study, we used in situ terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) to visualize the temporal and spatial distribution of apoptosis in the developing medaka embryo, which is a useful model for developmental biology and genetics. Most of the apoptotic cells were distributed in the central nervous system and tailbud. In the brain and retina, most of the apoptosis occurred in the restricted period. In situ hybridization against caspase 3A and caspase 3B showed that these were distributed in the tailbud and the head, respectively. These results suggested that two types of caspase 3 were involved in apoptosis in different areas
