Containment versus impingement: finding a compromise for cup placement in total hip arthroplasty
Recommendations for cup containment and impingement may provide conflicting directions for component orientation in total hip arthroplasty. For optimal containment, the cup is positioned with respect to the acetabular bone, resulting in coincidence of the rim of the cup and the acetabulum. This results in good coverage and symmetric load transfer, leading to good long-term stability, but occasionally necessitates more abduction of the cup than that recommended by the safe zone. On the other hand, placement of the cup for an optimal range of motion would lead to only partial containment, with a higher risk of component loosening and revision. The most effective compromise is to use a prosthesis that has a large safe zone, realised by a high head-to-neck ratio, and orienting the cup such that a good containment is achieved and the safe zone is respected. Computer navigation or smart aiming devices may help to find the best relative orientatio

Emergence of a Teicoplanin-Resistant Small Colony Variant of Staphylococcus epidermidis During Vancomycin Therapy
Small colony variants of Staphylococcus aureus can cause persistent and recurrent infections. There are only a few reports of small colony variants of coagulase-negative staphylococci. Herein a case of infection with a teicoplanin-resistant small colony variant of Staphylococcus epidermidis is presented. The small colony variant was isolated from blood cultures of a patient with acute leukaemia and therapy-induced neutropenia who was treated with vancomycin for catheter-associated bloodstream infection. Despite removal of the catheter and adequate antibiotic therapy, the infection did not clear and the patient died 20days after continuous antibiotic therap
ZTBus: A Dataset of 1000+ Complete, Second-Resolved Driving Missions of Inner-City Transit Buses
This paper presents the Zurich Transit Bus (ZTBus) dataset, which consists of
data recorded during driving missions of electric city buses in Zurich,
Switzerland. The data was collected over several years on two trolley buses as
part of multiple research projects. It involves more than a thousand missions
across all seasons, each mission usually covering a full day of operation. The
ZTBus dataset contains detailed information on the vehicle's power demand,
propulsion system, odometry, global position, ambient temperature, door
openings, number of passengers, dispatch patterns within the public
transportation network, etc. All signals are synchronized in time and include
an absolute timestamp in tabular form. The dataset can be used as a foundation
for a variety of studies and analyses. For example, the data can serve as a
basis for simulations to estimate the performance of different public transit
vehicle types, or to evaluate and optimize control strategies of hybrid
electric vehicles. Furthermore, numerous influencing factors on vehicle
operation, such as traffic, passenger volume, etc., can be analyzed in detail.Comment: This work has been submitted to Scientific Data for possible

FGB1 and WSC3 are in planta-induced beta-glucan-binding fungal lectins with different functions
In the root endophyte Serendipita indica, several lectin-like members of the expanded multigene family of WSC proteins are transcriptionally induced in planta and are potentially involved in beta-glucan remodeling at the fungal cell wall. Using biochemical and cytological approaches we show that one of these lectins, SiWSC3 with three WSC domains, is an integral fungal cell wall component that binds to long-chain beta 1-3-glucan but has no affinity for shorter beta 1-3- or beta 1-6-linked glucose oligomers. Comparative analysis with the previously identified beta-glucan-binding lectin SiFGB1 demonstrated that whereas SiWSC3 does not require beta 1-6-linked glucose for efficient binding to branched beta 1-3-glucan, SiFGB1 does. In contrast to SiFGB1, the multivalent SiWSC3 lectin can efficiently agglutinate fungal cells and is additionally induced during fungus-fungus confrontation, suggesting different functions for these two beta-glucan-binding lectins. Our results highlight the importance of the beta-glucan cell wall component in plant-fungus interactions and the potential of beta-glucan-binding lectins as specific detection tools for fungi in vivo
