Effect of a prolonged altitude expedition on glucose tolerance and abdominal fatness

In the present study, we investigated the effect of a long-term mountain expedition on glucose tolerance and insulin action. Twelve registered mountaineers ages 31 years (SD = 1.1) participated in a 25-day expedition at a 2,200-3,800-m altitude with an average duration of 8 hr per day. Arterial oxygen saturation (SaO2) was substantially reduced during hiking. Glucose tolerance and insulin responses were measured prior to and twice during the expedition period. Maximal oxygen consumption increased from 43.0 +/- 2.7 to 49.1 +/- 2.2 mL/kg/min. Percentage of body fat decreased from 19.4 +/- 6.8% to 16.9 +/- 5.9%. The area under the curves for insulin and glucose during the oral glucose tolerance test were also reduced in Days 3 and 25. The present study demonstrated that altitude hiking activity is an effective lifestyle intervention to improve insulin action.     

Review Article: Recent advancements in optofluidic flow cytometer

There is an increasing need to develop optofluidic flow cytometers. Optofluidics, where optics and microfluidics work together to create novel functionalities on a small chip, holds great promise for lab-on-a-chip flow cytometry. The development of a low-cost, compact, handheld flow cytometer and microfluorescence-activated cell sorter system could have a significant impact on the field of point-of-care diagnostics, improving health care in, for example, underserved areas of Africa and Asia, that struggle with epidemics such as HIV∕AIDS. In this paper, we review recent advancements in microfluidics, on-chip optics, novel detection architectures, and integrated sorting mechanisms.

血管紧张素转化酶基因I/D多态性与高血压脑梗塞发病的相关性

采用PCR方法分别检测82例高血压合并脑梗塞患者(BI)、67例单纯高血压患者(EH)和95例健康对照者(C)的血管紧张素转化酶(ACE)基因I/D多态性类型,并分析ACE基因I/D多态性分布与高血压合并脑梗塞发病的相关性.结果显示,BI组ACE基因的D/D基因型频率和D等位基因频率(分别为0.341和0.524)显著高于C组(分别为0.200和0.374,P<0.05)和EH组(分别为0.179和0.358,P<0.05),而EH组和C组ACE基因的D/D基因型频率和D等位基因频率无显著性差异.该研究结果表明,ACE基因的D/D基因型可能是高血压合并脑梗塞发病的独立危险因素.     

Naturalistic intervention for Asperger syndrome – a case study

On the basis of their cognitive abilities, children with Asperger syndrome are attractive candidates for inclusive education and, in Australia, most are in integrated settings. However, social interaction between children with Asperger syndrome and their peers remains problematic, with the children with Asperger syndrome often being left alone despite being among or near classmates. For classroom teachers, effective interventions in terms of class management are critical to facilitate positive social interaction between these two groups of children, and case studies can tell us a great deal about what works. In practice, a combination of intervention techniques may be best, in case a single one is ineffective, and in order to take advantage of potential synergies. In this article, Serene Choi, of the School of Education at the University of Newcastle (Australia) and Timo Nieminen, of the Centre for Biophotonics and Laser Science in the Department of Physics at the University of Queensland, report a naturalistic multiple-component intervention used to develop the social skills of a boy with Asperger syndrome in a mainstream school in Australia. This combined intervention, making use of social stories, simple peer modelling and individual lessons, appears to be a practical teaching method for inclusive education.

Predictors of Academic Success Among College Students With Attention Disorders

Among 68 students with attention deficit hyperactivity disorder, academic success was positively correlated with time management skills and freedom from financial stress. As a group, students with higher grade point averages reported fewer coping resources than did academically lower achieving students. Less academically successful students likely spend more time using coping mechanisms and therefore may have less time to study. Implications for professional practice and suggestions for future research are discussed.
