用ODO冷冻断裂法观察人膈腹膜间皮细胞和毛细血管的超微结构

ONO冷冻断裂法是一项新的扫描电镜制样技术。利用这项技术,将样品在-196℃下冷冻,然后把样品掰裂。用扫描电镜观察样品断裂面细胞的内部结构,具有较高的分辨率。并能显示细胞内部细胞器之间的关系。其缺陷是欲观察的断裂面不能预先确定,而是随机的。作者应用ODO冷冻断裂法,对人膈腹膜间皮细胞和毛细血管进行了观察.

Electronic Reserves: A Centralized Approach to the Scanning Process

ABSTRACT

Electronic reserves are being offered at colleges and Universities across the country creating an opportunity for collaboration between the library units of academic libraries. Library units with course reserves in medium and large academic libraries can capitalize on the benefits working with a centralized scanning unit, thus consolidating the scanning process of electronic reserves processing. The cooperation between library units to provide better service results in a positive relationship between course instructors, students, and the library.     

An evaluation of personalised insoles developed using additive manufacturing

Abstract

The aim of the study was to evaluate the short and medium term use of personalised insoles, produced by combining additive manufacturing (AM) with three-dimensional (3-D) foot scanning and computer aided design (CAD) systems. For that, 38 runners (19 pairings) were recruited. The experimental conditions were: personalised and control. The personalised condition consisted of trainers fitted with personalised glove fit insoles manufactured using AM and using foot scans to match the plantar geometry of the feet. The control condition consisted of the same trainers fitted with insoles also manufactured using AM but using scans of the original insole shape. Participants were allocated to one of the experimental conditions and wore the trainers for 3 months. Over this period they attended three laboratory sessions (at months 0, 1.5 and 3) and completed an Activity Diary after each training session. The footwear was evaluated in terms of discomfort and biomechanics. Lower discomfort ratings were found in the heel area (P ≤ 0.05) and for overall fit (P ≤ 0.05), with the personalised insole. However, discomfort was reported under the arch region for both conditions. With regard to the biomechanical data, differences between conditions were detected for ankle dorsiflexion at footstrike (P ≤ 0.05), maximum ankle eversion (P ≤ 0.05) and peak mean pressure under the heel (P ≤ 0.01): the personalised condition had lower values which may reduce injury risk. The personalisation of the geometry of insoles through advances in AM together with 3-D scanning and CAD technologies can provide benefits and has potential.
