During knee flexion, the human patella moves along a complex path resulting from the combined actions of articular contact and soft-tissue stabilization. The current study is an attempt to characterize the role of these soft structures on patellar kinemati ...
The common approach to assess the stabilizing role of the ACL in the knee has been to measure the elongation of a few marked fibers in the ligament. A comparison of the relative elongation (RE) of these marked fibers between different specimens and studies ...
Motivated by applications in orthopaedic surgery, new constitutive laws for trabecular (or spongious) bone are developed in the framework of continuum mechanics, implemented in a mechanical analysis computer program, validated by a number of in vitro exper ...
When treated with BuLi in the presence of Na or K tert-butoxide, 2-(trimethylsilyl)- and 2-(triethylsilyl)norbornadiene undergo H/metal-exchange mainly at the 5-position. The latter position is slightly activated relative to unsubstituted norbornadiene whi ...
7-Halo-7-methylnorcaranes (I) and 7,7-dimethylnorcarane (II) are formed via replacement of halogen by Me during the reaction of cyclohexene (III) with carbenes (carbenoids) and MeLi. Thus, III is treated with CHClF2 or CCl2F2 and MeLi to give a mixt. of 7- ...
