传统武术与竞技武术差异之比较

通过对传统武术与竞技武术在技术特征及价值取向的差异比较，力球深刻把握两者的特点：在技术特征上，传统武术由形架入手，继而求化神还虚，竞技武术更强调动作的规范、统一，以利于竞赛；在价值取向上，传统武术突出以提高技击能力为主体价值的“体用兼备”，而竞技武术则是为参加符合规则的比赛，取得优异的运动成绩。     

Modulation of an activity response with associative and nonassociative fear in the rat: A lighting differential influences the form of defensive behavior evoked after fear conditioning

Rats confronted with the onset of a light gradient display a transient increase in locomotion called theactivity response (AR) and a dark preference (Godsil & Fanselow, 2004). These experiments demonstrate that the magnitude of the AR can be blunted with Pavlovian fear-conditioning procedures via associative and nonassociative fear. Although manifested in decreased locomotion, the blunted AR effect was not due to increased freezing or immobility behaviors. Instead, rats displayed reduced rearing and an increase in a class of behaviors calledstationary activity. These results suggest that the lighting differential supplied by the cue influences the topography of defensive behavior and reduces the expression of freezing. This procedure provides a means by which to examine learned and unlearned defensive responses to the same stimulus.     

Microfluidic three-dimensional hydrodynamic flow focusing for the rapid protein concentration analysis

A simple microfluidic 3D hydrodynamic flow focusing device has been developed and demonstrated quantitative determinations of quantum dot 525 with antibody (QD525-antibody) and hemagglutinin epitope tagged MAX (HA-MAX) protein concentrations. This device had a step depth cross junction structure at a hydrodynamic flow focusing point at which the analyte stream was flowed into a main detection channel and pinched not only horizontally but also vertically by two sheath streams. As a result, a triangular cross-sectional flow profile of the analyte stream was formed and the laser was focused on the top of the triangular shaped analyte stream. Since the detection volume was smaller than the radius of laser spot, a photon burst histogram showed Gaussian distribution, which was necessary for the quantitative analysis of protein concentration. By using this approach, a linear concentration curve of QD525-antibody down to 10 pM was demonstrated. In addition, the concentration of HA-MAX protein in HEK293 cell lysate was determined as 0.283 ± 0.015 nM. This approach requires for only 1 min determining protein concentration. As the best of our knowledge, this is the first time to determinate protein concentration by using single molecule detection techniques.     

Study of C-Reactive Protein and Myocardial Infarction in the Indian Population

To analyse the association of high sensitivity C-reactive (hsCRP) protein levels and −717A/G single nucleotide polymorphism of CRP with acute myocardial infarction (AMI) in the Indian population. Study population included 100 MI cases wherein 32 patients had experienced previous MI (MI-Group-1), 68 MI cases were recruited at presentation (MI-Group-2) and equal number of age and gender matched healthy individuals. hsCRP levels were determined by ELISA and genotyping of −717A/G was carried out by polymerase chain reaction-based restriction digestion method. The −717A/G genotypes did not influence hsCRP level and their distribution did not differ between groups. However, in the present study hsCRP demonstrated significant correlation with BMI in controls of both the genders and with triglycerides in females of AMI at presentation who otherwise are with low risk profile. Identifying traditional risk factors associated with inflammation may help in controlling the acute event.     

A Comparative Study of Bone Scan Findings and Serum Levels of Tumor Marker CA15-3 in Patients with Breast Carcinoma

Breast cancer is one of the most frequent malignancies in the world. Available staging procedures to detect breast cancer are bone scan, chest X-ray, liver ultrasonography, computerized tomography, estimation of tumor markers like carbohydrate antigen (CA15-3) and carcino embryonic antigen. These procedures are expensive and may not be required in all cases. Out of 70 patients studied, 55 had normal CA15-3 and 15 had elevated levels of Ca15-3. Eight (14.5%) of the 55 patients with normal CA15-3 had abnormal bone scan. Fifteen patients had CA15-3 levels above the normal range and among these 9 (60%) had abnormal bone scan. While prime facie it would appear that a high level of CA15-3 correlate with abnormal bone scan, it is also true that the numbers are small at present and conclusions about the validity of CA15-3 as marker of bone metastasis may be premature.     

体育院校大学生完美主义心理与成绩之间的关系

完美主义是一种习惯性的思维方式和稳定的人格特征,它是在人的成长过程中,内、外部环境相互影响的结果,是个人在不同情况下表现出来的稳定的人格特征。这种凡事追求完美的人格特征在成绩优秀的人群中间,比如像大学生、研究生等,体现的十分明显。这种特质会影响人的处事方式、看事态度、工作学习成绩等。采用《中文Frost多维完美主义量表》,研究随机抽取了武汉体育学院大一到大四的200名学生进行调查,并将他们的调查结果与其成绩排名联系在一起进行分析研究。     

阶级范畴及其与体系的关系研究

学者对阶级这一范畴的研究始于17世纪资本主义时期,由于历史和阶级的局限均未能对阶级产生的历史过程和经济根源作出全面科学的概括和解释。马克思和恩格斯第一次科学地分析了阶级的历史起源、产生根源等问题,揭示了阶级的本质,最终指出无产阶级是推翻资本主义、摧毁一切奴役制度、实现全人类最终解放的伟大力量。马恩阶级理论作为马克思主义的基础理论之一,是历史唯物主义的重要组成部分。
