#1
Hans Zwipp, Michael Borrmann, Eberhard Walter
The goal of this paper is to report our experience with hindfoot fractures using our specially developed boot, with a follow-up of 557 cases. This boot works like the well-known Allgöwer-Röck ortheses (ARO), but is a hybrid between a boot and an orthesis. It allows full weightbearing without using crutches and completely protects an acutely operated hind foot fracture, hind foot arthrodesis or a hind foot fracture which is suitable for conservative treatment. In its first generation, this boot was custom made and used in 408 cases, from March 1999 to February 2011...

Background MRSA represents a considerable health threat to orthopaedic patients. Throughout the last decade, livestock-associated MRSA emerged increasingly in livestock all over Europe. LA-MRSA broke the species barrier, colonizing and causing infections in humans. Nevertheless, to date there are no studies concerning livestock-associated MRSA and orthopaedic patients. Therefore, we aimed to investigate the prevalence of LA-MRSA in a regional orthopaedic department localized in an area with high-density livestock...

The phosphorylation of agonist-occupied G-protein-coupled receptors (GPCRs) by GPCR kinases (GRKs) functions to turn off G-protein signaling and turn on arrestin-mediated signaling. While a structural understanding of GPCR/G-protein and GPCR/arrestin complexes has emerged in recent years, the molecular architecture of a GPCR/GRK complex remains poorly defined. We used a comprehensive integrated approach of cross-linking, hydrogen-deuterium exchange mass spectrometry (MS), electron microscopy, mutagenesis, molecular dynamics simulations, and computational docking to analyze GRK5 interaction with the β2-adrenergic receptor (β2AR)...

Social housing of rhesus macaques (Macaca mulatta) is considered to be the cornerstone of behavioral management programs in biomedical facilities. However, it also involves the risk of socially inflicted trauma. The ability to avoid such trauma would contribute to the animals' well-being and alleviate staff's concerns, thus paving the path for more introductions. Here, we sought to address the conflict between the need to socially house rhesus macaques and the need to bring social wounding to a minimum by identifying behaviors expressed early in social introductions, that may serve as predictors of later wounding events...

Motivation: The accuracy of predicting protein local and global structural properties such as secondary structure and solvent accessible surface area has been stagnant for many years because of the challenge of accounting for non-local interactions between amino acid residues that are close in three-dimensional structural space but far from each other in their sequence positions. All existing machine-learning techniques relied on a sliding window of 10-20 amino acid residues to capture some "short to intermediate" non-local interactions...

Infrared cameras are becoming increasingly popular in clinical applications as they allow fast, non-contact temperature measurements. As abnormal heat distribution can indicate illness, infrared cameras have been applied in the prediction, diagnosis and monitoring of conditions (Lahiri, Bagavathiappan, Jayakumar, & Philip, 2012). Current practices, however, often overlook the importance of emissivity when taking thermal measurements. The consensus is that human skin has an emissivity of 0.98 (Soerensen et al...

We investigate the relationship between the Zeeman interaction and the inversion-asymmetry-induced spin-orbit interactions (Rashba and Dresselhaus SOIs) in GaAs hole quantum point contacts. The presence of a strong SOI results in the crossing and anticrossing of adjacent spin-split hole subbands in a magnetic field. We demonstrate theoretically and experimentally that the anticrossing energy gap depends on the interplay between the SOI terms and the highly anisotropic hole g tensor and that this interplay can be tuned by selecting the crystal axis along which the current and magnetic field are aligned...

BACKGROUND: Keratin has shown promising outcomes as a biomaterial due to its inherent bioactivity, biocompatibility and regenerative effects. The effect of keratin on repair and regeneration of dental tissues has never been studied before. Current therapies to treat pulp tissues involve its replacement with inert, synthetic materials that do not have a proper biological function, leading to failure and tooth loss. This study aimed to develop a biocompatible keratin hydrogel (KH) suitable for pulp therapies...

BACKGROUND: Transurethral intracorporeal lithotripsy is the modality of choice for the endoscopic disintegration of large, long-standing, radiolucent or high-density stones. Despite several advantages and proven benefits of contact ureterolithotripsy/ureterolithoextraction (CULT), the application of irrigation carries significant risks of untoward perioperative events including retrograde stone migration and postoperative pyelonephritis. METHODS: We describe a new technique - endoscopic intracorporeal lithotripsy in the gas (СО2) medium...

For the successful treatment of infections, real-time analysis and enhanced multiplex capacity, sensitivity and cost-effectiveness of the developed detection method are critical. In this work, surface-enhanced Raman scattering (SERS) was employed with the final aim of identification and discrimination of pathogenic bacteria, based on their detected SERS fingerprint at the single-cell level. Several genera of bacteria that are found in most of the isolated infections in bacteraemia were successfully identified in less than 5 minutes without the use of antibodies or other specific receptors...

We propose and investigate a Schottky contact detector where the contact metal is a nanoscale metal stripe waveguide supporting surface plasmons with strong localization along the Schottky contact. We consider Au for the metal stripe, p-doped silicon for the semiconductor, operation in the infrared (at λ<sub>0</sub>=1550  nm), and internal photoemission as the sub-bandgap detection mechanism. We find that the main surface plasmon mode of operation of the Au stripe exhibits diverging real and imaginary parts of n<sub>eff</sub> with decreasing stripe dimensions, commensurate with increasing confinement...

We describe a catadioptric monocentric imager using an elastic central element focused by deformation of a fold mirror. We show the design of 6 mm and 12 mm focal length F/2.8 achromats and compare design performance when focusing by translating the sensor, translating the fold mirror, and by spherically deforming the fold mirror. We tested the 12 mm focal length design using a diamond turned polystyrene element as the outer meniscus lens (and mechanical mount), filled with an optical gel in contact with the central aperture and fold mirror, and demonstrate focusing by mechanical deformation of the fold mirror...

The Mycobacterium fortuitum plasmid, pAL5000, is the most-studied member of a family of plasmids that are found in Actinobacteria. Its replication is brought about by the combined action of two plasmid-encoded replication proteins, RepA and RepB. RepB has earlier been shown to be a sigma factor homologue that possesses origin-binding activity. The mechanism by which RepA functions, and its relationship with RepB, if any, has not been explored yet. In this study, we show that RepA shares a common catalytic domain, with proteins belonging to the primase-polymerase and DNA polymerase X families...
