Kinematic analysis of leg alignment during conventional versus navigated total knee arthroplasty: initial results of a prospective study.

Current kinematic navigation systems provide real-time spatial analyses of leg alignments during total knee arthroplasty (TKA) instead of delayed radiographic verification after surgery. A prospective study was conducted to investigate leg alignments of TKAs that underwent different surgical guidance [intramedullary (IM) jig-based vs. navigation-assisted] using a kinematic navigation system.

Digitally synchronized LCD projector for multi-color fluorescence excitation in parallel capillary electrophoresis detection.

A simple method is proposed for modulating the excitation light used for multi-color fluorescence detection in a single capillary electrophoresis (CE) channel. In the proposed approach, a low-cost commercial liquid crystal device (LCD) projector with digitally-modulated LCD switches is used to provide the illumination light source and the fluorescence emitted from the CE chip is synchronously detected using an ultraviolet-visible-near infrared (UV-vis-NIR) spectrometer. The modulated light source enables the detection of multiple fluorescence signals within a single CE channel without the need of mechanically switching optical components.

Objective-type dark-field system applied to multi-wavelength capillary electrophoresis for fluorescent detection and analysis.

This paper presents an advanced diascopic illumination technique for simultaneous multi-wavelength fluorescence excitation and detection without using any spatial filter sets. The proposed system includes a home-built dark-field condenser comprising a high N.A.
