Over the years a variety of cartilage restorative procedures have been developed for athletes to address focal, full-thickness cartilaginous defects in the knee joint, including microfracture, osteochondral autografts, osteochondral allografts, autologous chondrocyte implantation (ACI), and most recently, next-generation ACI involving scaffolds or cell-seeded scaffolds. Since its introduction, ...

We report on progress towards the development of an Action Concept Inventory (ACI), a test that measures student understanding of action principles in introductory mechanics and optics. The ACI also covers key concepts of many-paths quantum mechanics, from which classical action physics arises. We used a multistage iterative development cycle for incorporating expert and student feedback into s...

ACI Rossignol is composed of teams from LIF (UMR 6166), LSV (UMR 8643), INRIA Futurs (Projet Comète and projet SECSI) and Verimag (UMR 9939). The research topic of the action is ccryptographic protocol verification. Two general meetings have been held and additional meetings between sites have been organized. Futhermore the action has organized a Spring School on formal aspects on Security (Sec...

BACKGROUND We investigated whether routine elective irradiation of a clinically negative inguinal node (IGN) is necessary for patients with locally advanced distal rectal cancer and anal canal invasion (ACI). METHODS We reviewed retrospectively 1,246 patients with locally advanced rectal adenocarcinoma managed using preoperative or postoperative chemoradiotherapy and radical surgery between 2...

BACKGROUND We sought to evaluate the test characteristics of the acute cardiac ischemia time-insensitive predictive instrument (ACI-TIPI) in relation to 30-day major adverse cardiac events (MACE) among patients who presented to the Emergency Department with symptoms suggestive of an acute coronary syndrome. We then examined the test characteristics of various dichotomous ACI-TIPI cut points. ...

BACKGROUND Neuropeptide Y (NPY) is an important central orexigenic hormone predominantly produced by the hypothalamus, and recently found to be secreted in adipose tissue (AT). Acipimox (Aci) inhibits lipolysis in AT and reduces plasma glycerol and free fatty acid (FFA) levels. Exercise and Aci are enhancers of growth hormone (GH) and NPY secretion and exercise may alter leptin levels. We expec...

A structure may be subject to several aftershocks after a mainshock. In many seismic design provisions, the effect of sequences is either not directly considered or has been underestimated. This study examined behavior reinforced concrete (RC) moment-resisting structures with shear walls under sequences. Two three-dimensional short and medium height were designed analyzed seven real mainshock–a...
