1太湖首次发现楯螺和尖膀胱螺(英文)显示文摘在太湖湖洲和五里湖水域分别首次发现了2种可能是入侵的螺类楯螺(Ferrissia wautieri MIROLLI 1960)和尖膀胱螺(Physa acuta DRAPARNAUD 1805)。它们均属肺螺亚纲,基眼目。文章对其形态、生物学特征进行了描述,对其可能的入侵途径等进行了讨论。BECKMANN Melanie C 何全源 杨健 徐跑 2006南方水产2006,2,6:10

3同步构绘学龄儿童脑模版和生长曲线显示文摘大脑的生长发育曲线和各年龄的标准脑模版是研究个体发育异常的必要工具.本研究构建了以一岁为间隔的儿科脑模版及相应的脑发育轨线,探究了年龄和民族在儿科脑影像研究中的影响.本研究使用了来自中美共四个站点且实验设计相同的两组纵向加速儿童脑影像队列数据,对正常发育的学龄儿童间隔五个季节进行了三次磁共振扫描.我们分别构建并比较了不同民族和年龄阶段的脑模版及发育轨线.对457名和133名正常发育的中美儿童青少年进行了总计674次和190次磁共振扫描.我们评估了使用不同民族和年龄阶段的脑模版进行配准产生的形变量,并建模大脑皮层400个不同区域体积的生长曲线.分析结果表明:构建各年龄阶段和民族特异性的脑模版对于脑生长发育曲线的绘制是必要的.脑体积在不同民族间的发育差异主要体现在结构和功能上个体差异较为明显的外侧额叶和顶叶区域,使用年龄和民族相对应的脑模版可以避免在构绘脑生长曲线时由此产生的系统偏差.本研究的所有结果及分析代码均已公开.董昊铭 F.Xavier Castellanos 杨宁 张喆 周荃 何叶 张蕾 徐婷 Avram J.Holmes B.T.Thomas Yeo 陈飞燕 王滨 Christian Beckmann Tonya White Olaf Sporns 邱江 冯廷勇 陈安涛 刘勋 陈旭 翁旭初 Michael P.Milham 左西年 2020Science Bulletin2020,65,22:4

5Does knowledge of physical activity recommendations increase physical activity among Chinese college students? Empirical investigations based on the transtheoretical model显示文摘Background: Based on the transtheoretical model, the current study investigated whether awareness of physical activity(PA) recommendations had an impact on the stages of PA behavior change and levels of PA among Chinese college students.Methods: In Study 1, with a cross-sectional study design, 9826 students were recruited, and their knowledge of international PA recommendations,PA stage distribution, and self-reported PA level were surveyed. Pearson's χ2 test was used to test whether those participants who were aware and not aware of PA guidelines were equally distributed across the stages of PA behavior, and independent t test was conducted to test the group difference in the actual levels of PA. In Study 2, 279 students who were not aware of the PA recommendations were randomly allocated to either an intervention group or a control group, and only those in the intervention group were presented with international PA guidelines. In both groups,students' PA stages and PA level were examined before the test and then 4 months post-test. Mc Nemar's test for correlated proportions and repeated-measures analysis of variance were conducted to examine the changes in PA stage membership and PA level after the intervention.Results: Study 1 results revealed that only 4.4% of the surveyed students had correct knowledge of PA recommendations. Those who were aware of the recommendations were in later stages of PA behavior(χ~2(4) = 167.19, p < 0.001). They were also significantly more physically active than those who were not aware of the recommendations(t(443.71) = 9.00, p < 0.001, Cohen's d = 0.53). Study 2 results demonstrated that the intervention group participants who were at the precontemplation and contemplation stages at the pre-test each progressed further in the PA stages in the post-test(χ~2(1) = 112.06, p < 0.001; χ~2(1) = 118.76, p = 0.03, respectively), although no significant change in PA level was observed(t(139) < 1, p = 0.89).Conclusion: The results showed that awareness of the PA recommendations was associated with higher stages and levels of PA behavior, and a brief educational exposure to PA recommendations led to improved stages of PA behavior but no change in the levels of PA among Chinese college students. More effective public health campaign strategies are needed to promote the dissemination of the PA recommendations and to raise the awareness of the Chinese student population.Kahar Abula Peter Gropel Kai Chen Jürgen Beckmann 2018Journal of Sport and Health Science2018,7,1:3

10Functional outcomes assessment in shoulder surgery显示文摘The effective evaluation and management of orthopaedic conditions including shoulder disorders relies upon understanding the level of disability created by the disease process. Validated outcome measures are critical to the evaluation process. Traditionally, outcome measures have been physician derived objective evaluations including range of motion and radiologic evaluations. However, these measures can marginalize a patient's perception of their disability or outcome. As a result of these limitations, patient self-reported outcomes measures have become popular over the last quarter century and are currently primary tools to evaluate outcomes of treatment. Patient reported outcomes measures can be general health related quality of life measures, health utility measures, region specific health related quality of life measures or condition specific measures. Several patients self-reported outcomes measures have been developed and validated for evaluating patients with shoulder disorders. Computer adaptive testing will likely play an important role in the arsenal of measures used to evaluate shoulder patients in the future. The purpose of this article is to review the general health related quality-of-life measures as well as the jointspecific and condition specific measures utilized in evaluating patients with shoulder conditions. Advancesin computer adaptive testing as it relates to assessing dysfunction in shoulder conditions will also be reviewed.James D Wylie James T Beckmann Erin Granger Robert Z Tashjian 2014World Journal of Orthopedics2014,5,5:2
