Background: Complex regional pain syndrome (CRPS) is one of the serious complications after surgical treatment of a rotator cuff tear. Both a measurement of body surface temperature and bone scintigraphy have been used as diagnostic tools for the early phase of CRPS.Unfortunately, few studies have been carried out that applied these methods to the patients after rotator cuff repair.
Purposes: To clarify both shoulder surface temperature and bone scintigraphy findings in patients with rotator cuff tears.
Subjects And Methods: Subjects comprised patients with unilateral rotator cuff tears (five men and five women, mean age 61 years). For measurements of shoulder surface temperature, a Thermochron was attached to both shoulders. As for bone scintigraphy, intravenous injection of technetium-labelled hydroxymethylenebisphosphonic acid (99mTc-HMDP)was performed, and then images were taken with a gamma camera.
Results: During the measurements, the changes in body surface temperature for the affected and healthy shoulders remained within the standard deviation of the reference group. The intensity of radioisotope (RI) uptake for the affected shoulder joint was significantly increased compared to that for the healthy shoulder joint (P < 0.05).
Conclusion: RI uptake is increased in shoulders with rotator cuff tears, whereas shoulder surface temperature shows no differences on the affected and unaffected sides.

The strong solid-liquid interaction leads to the complicated occurrence characteristics of shale oil. However, the solid-liquid interface interaction and its controls of the occurrence state of shale oil are poorly understood on the molecular scale. In this work, the adsorption behavior and occurrence state of shale oil in pores of organic/inorganic matter under reservoir conditions were investigated by using grand canonical Monte Carlo (GCMC) and molecular dynamics (MD) simulations.

Aerogels hold great potential in thermal insulation, catalytic supports, adsorption, and separation, due to their low density, high porosity, and low thermal conductivity. However, their inherent mechanical fragility and limited control functionality pose substantial challenges that hinder their practical use. In this study, a strategy is developed for the fabrication of cross-linked aramid nanofiber aerogels (cANFAs) by combining internanofiber surface cross-linking with ice-templating techniques.

Hydrogen spillover is an important process in catalytic hydrogenation reactions, facilitating H activation and modulating surface chemistry of reducible oxide catalysts. This study focuses on the unveiling of platinum-induced hydrogen spillover on monoclinic tungsten trioxide (γ-WO), employing ambient pressure X-ray photoelectron spectroscopy, density functional theory calculations and microkinetic modeling to investigate the dynamic evolution of surface states at varied temperatures. At room temperature, hydrogen spillover results in the formation of W and hydrogen intermediates (hydroxyl species and adsorbed water), facilitated by Pt metal clusters.

Characterising patterns of genetic diversity including evidence of local adaptation is relevant for predicting and managing species recovering from overexploitation in the face of climate change. Red abalone (Haliotis rufescens) is a species of conservation concern due to recent declines from overharvesting, disease and climate change, resulting in the closure of commercial and recreational fisheries. Using whole-genome resequencing data from 23 populations spanning their entire range (southern Oregon, USA, to Baja California, MEX) we investigated patterns of population connectivity and genotype-environment associations that would reveal local adaptation across the mosaic of coastal environments that define the California Current System (CCS).

A combined AFM/MS method was employed for protein registration in solution. This method is based on reversible specific capturing of a target protein from a large volume of analyzed solution onto a small sensor area of a chip with immobilized aptamer ligands. Fishing of the core antigen of hepatitis C virus (HCVcoreAg) from 10 M solution of this protein in buffer was carried out.
