A new method for the spectroscopic study of absorbing films is proposed. In contrast to the well-established methods that take advantage of the attenuation of total internal reflection (ATR) to obtain spectra, we intentionally arrange the optics to permit partial internal reflection from the sampling prism face. Attenuated partial internal reflection (APR) spectroscopy is introduced through the...

Objective: To evaluate frame constructs, surgical technique, postoperative care, complications, treatment duration, and outcome of circular external fixation (CEF) for treatment of 30 antebrachial and crural angular deformities in dogs. Study Design: Retrospective study. Sample Population: Twenty-seven dogs with limb deformities. Methods: Medical records of dogs that underwent surgery with CEF ...

Very little is known about the influence of the mechanical environment on the healing of large segmental defects. This partly reflects the lack of standardised, well characterised technologies to enable such studies. Here we report the design, construction and characterisation of a novel external fixator for use in conjunction with rat femoral defects. This device not only imposes a predetermin...

BACKGROUND The purpose of this study was to evaluate the factors that influence residual angulation after treating pediatric distal tibial diaphyseal fractures. METHODS We retrospectively reviewed the records of 75 children under the age of ten who were treated at two referral centers for distal tibial diaphyseal fractures. The mean patient age was 6.8 ± 2.3 years, and the mean follow-up dura...

OBJECTIVE To present the results from using biological ceramics for filling bone defects resulting from post-traumatic or orthopedic injuries. METHODS Thirty-six patients with bone defects caused by trauma or orthopedic injury were evaluated. Nineteen patients were male (52.8%) and 17 were female (47.2%). Their ages ranged from 19 to 84 years, with a mean of 45.7 years and median of 37 years....

The study describes a computational approach for predicting the mechanical response of different configurations of the Ilizarov external fixation system. The Ilizarov type fixators are now being used to an increasing extend to stabilize bone fractures and for limb lengthtening [5,6] and its functions are investigated using numerical [e.g. 3,7] and experimental [e.g. 1,2] techniques. The device ...

A Cu(II)-sensing, ratiometric, and selective fluorescent sensor 1, N-butyl-4,5-di[(pyridin-2-ylmethyl)amino]-1,8-naphthalimide, was designed and synthesized on the basis of the mechanism of internal charge transfer (ICT). In aqueous ethanol solutions of 1, the presence of Cu(II) induces the formation of a 1:1 metal-ligand complex, which exhibits a strong, increasing fluorescent emission centere...

Probe has been developed as the first ratiometric fluorescent cobalt probe with high sensitivity and selectivity based on internal charge transfer (ICT). Most importantly, the probe achieved the imaging and detection of cobalt in cells with ratiometric measurement.
