健身瑜伽对改善中年女性形态和提高柔韧性效应的实验研究

为研究健身瑜伽对女性形体和柔韧性方面的锻炼效果，对62名中年女性进行分组实验，在训练前后对各组进行身体形态和柔韧性指标测试．研究结论：健身瑜伽对腰腹、大腿部的减脂降围有所改善，对形体改善的全面性效应没有健美操明显，但在柔韧性改善方面，健身瑜伽比健美操效果显。     

论教育评论形态

教育评论形态是指教育评论的形式和状态,它是教育评论学研究的理论问题之一.教育评论形态的划分依人们视点的不同而万紫千红.按教育评论主体的不同可以分为:大众教育评论、专家教育评论、行家教育评论.大众教育评论是基础;专家教育评论是基于大众教育评论基础上的专业性评论,是行家教育评论的基础;而行家教育评论则是立足于大众教育评论,建立在专家教育评论之上的"教育评论金字塔"塔顶.     

试析现代远程教育、网络教育与E-Learning

近年来,现代远程教育、网络教育、E-learning等相近的名词术语出现的频率越来越高,读者很容易将其混淆.清晰辨别这三者,有利于更好地把握我国现代远程教育发展的方向,对培养更加科学的研究态度具有重大意义.本文从阐述这三者的含义出发,试图对其进行辨析,指出三者的区别和联系,最后指出了辨析这三个概念的意义.     

有氧舞蹈对高校女大学生体质的影响

运用文献资料法、数理统计法和实验法,对60名女大学生进行16周的有氧舞蹈训练,研究有氧舞蹈对大学女生身体形态、素质、机能的影响。结果显示：实验后女生的体脂百分率和腰臀比存在显著性差异,体重变化不大;800m、立定跳远、1min仰卧起坐存在显著性差异,坐位体前屈无明显变化;肺活量和最大吸氧量指标显著提高,呼吸频率降低。结论：有氧舞蹈能促进女大学生体内多余脂肪的燃耗,减少体脂肪;发展腰腹部力量以及腿部力量;锻炼呼吸器官的功能,提高心肺的工作能力。

Quantitative detection of cells expressing BlaC using droplet-based microfluidics for use in the diagnosis of tuberculosis

This paper describes a method for the quantitative detection of cells expressing BlaC, a β-lactamase naturally expressed by Mycobacterium tuberculosis, intended for the diagnosis of tuberculosis. The method is based on the compartmentalization of bacteria in picoliter droplets at limiting dilutions such that each drop contains one or no cells. The co-encapsulation of a fluorogenic substrate probe for BlaC allows the quantification of bacteria by enumerating the number of fluorescent drops. Quantification of 10 colony forming units per milliliter is demonstrated. Furthermore, the encapsulation of single cell in drops maintains the specificity of the detection scheme even when the concentration of bacteria that do not express BlaC exceeds that expressing BlaC by one million-fold.     

A multiple-dose pharmacokinetics of polyethylene glycol recombinant human interleukin-6 (PEG-rhIL-6) in rats

Radiation therapy has been widely applied in cancer treatment. However, it often causes thrombocytopenia (deficiency of white blood cells) as an adverse effect. Recombinant human interleukin-6 (rhIL-6) has been found to be a very effective way against this thrombocytopenia, but IL-6 has low stability in blood, which reduces its efficacy. To increases the stability and half-life of rhIL-6, it was modified by polyethylene glycol (PEG). The pharmacokinetics and the tissue distribution of PEG-rhIL-6 labeled with ¹²⁵I were examined after subcutaneous injection in rats. The pharmacokinetic pattern of PEG-rhIL-6 was defined with linear-kinetics, and we fitted a one-compartment model with half-lives of 10.44–11.37 h (absorption, t _{1/2K a}) and 19.77–21.53 h (elimination, t _1/2Ke), and peak concentrations at 20.51–21.96 h (t _peak) in rats. Half-lives and t _peak of PEG-rhIL-6 were longer than those of rhIL-6 previously reported. In the present study, for deposition of PEG-rhIL-6 in rats, the tissue distribution examination showed that blood was the major organ involved, rather than liver. However, as to the elimination of PEG-rhIL-6, the major organ was the kidney. The excretion fraction of the injection dose recovered from urine was 23.32% at 192 h after subcutaneous administration. Less than 6% of PEG-rhIL-6 was eliminated via the feces at 192 h. These results indicate that PEG-rhIL-6 is a good candidate drug formulation for patients with cancer.
