The purpose of this study was to determine the accuracy of fluoroscopy in judging tibial plateau articular reduction.

Methods: Ten embalmed human cadavers were selected.

Reliability in Measuring Preinjury Physical Function in Orthopaedic Trauma.

Objective: In orthopaedic trauma, patients' functional status scores cannot be collected before injury. Due to the lack of these data, it is difficult to reliably determine if patients have returned to their preinjury level of physical function. The goal of this article is to determine if patients' assessment of preinjury function agrees with that of familiar proxies, to determine whether patient assessment of preinjury function may be regarded as reliable.

Avoiding Resistance Limitations in High-Performance Transparent Supercapacitor Electrodes Based on Large-Area, High-Conductivity PEDOT:PSS Films.

Unlabelled: This work describes the potential of thin, spray-deposited, large-area poly(3,4-ethylenedioxythiophene)/poly(styrene-4-sulfonate) (

Pedot: PSS) conducting polymer films for use as transparent supercapacitor electrodes. To facilitate this, we provide a detailed explanation of the factors limiting the performance of such electrodes. These films have a very low optical conductivity of σop = 24 S/cm (at 550 nm), crucial for this application, and a reasonable volumetric capacitance of CV = 41 F/cm(3).

Intraarticular Matrix Metalloproteinases and Aggrecan Degradation Are Elevated After Articular Fracture.

Background: Posttraumatic osteoarthritis (OA) is a variant of OA that can develop after articular injury. Although the mechanism(s) of posttraumatic OA are uncertain, the presence and impact of postinjury proteolytic enzymes on articular cartilage remain unknown. To our knowledge, there are no studies that evaluate the presence of matrix metalloproteinases (MMPs) or aggrecan degradation after articular fracture.

Analytical evaluation of the Diazyme glycated serum protein assay on the siemens ADVIA 1800: comparison of results against HbA1c for diagnosis and management of diabetes.

Hemoglobin A1c (HbA1c) is considered the gold standard for assessment of glycemic control in diabetic patients. HbA1c is inadequate in individuals homozygous or compound heterozygous for hemoglobin variants or in conditions with an altered red blood cell turnover. In these cases glycated albumin (GA) is proposed as an alternative assay.
