Objective To evaluate the efficacy of a novel dynamic distraction external fixator for proximal interphalangeal joint (PIPJ) fracture-dislocation. Methods From March 2005 to March 2014, 20 patients with PIPJ fracture-dislocation were treated with our technique. Function scores according to the Michigan Hand Outcome Questionnaire (MHQ) score, union time, grip strength, and range of motion (ROM) were recorded before and after treatment. Results All patients completed a mean follow-up of 22 months (range, 12-60 months). All patients achieved fracture union and joint reduction. The mean union time was 3 months (range, 2-6 months). The mean postoperative MHQ score was 88.00 +/- 3.42 (range, 84.00-92.00). Postoperative grip strength of the affected sides was 92% of the contralateral sides. X-rays showed that the fracture line disappeared completely with a good joint contour. The range of extension in the PIPJ was -5 degrees (range, -10 degrees-0 degrees). The range of flexion in the PIPJ was 89.40 degrees +/- 9.79 degrees (range, 75 degrees-100 degrees). Postoperatively, four patients had slight narrowing of the joint space and two had an uneven articular surface. Pin breakage, loosening, and tract infection were not observed. Conclusions The novel dynamic distraction external fixator is a promising option for PIPJ fracture-dislocation.
Female participants in different perilous tasks including law enforcement offices have been considerably increased in the last few decades. However, they mostly wear men's body armour with smaller sizes which brings a negative upshot not only in ballistic protection performance, comfort, fitness but also in a psychological point of view. Hence, manufacturing female soft body armour based on their unique morphological differences for better ballistic protection without conceding fitness and comfort are in great demand. This research work presented a novel method using a systematic 3D design approach through parametrization process to generate block patterns for manufacturing successive layer in the panels. The deformable mesh on the 3D virtual adaptive female model was developed with grading values of zero. Parametrization process based on the thickness of each layer in the 3D design database was applied to generate the different successive meshes on the virtual mannequin with appropriate coordinates. Later, the multi-layers mesh developed on the virtual 3D female body has been flattened to acquire the different layer's pattern. Due to its excellent mouldability behaviour, 3D warp interlock fabrics made of high-performance fibre has been designed and developed to manufacture the seamless female body armour with a dome-formation process. The manufactured multi-layer panels were draped on the standard female physical mannequin for experimental validations. The result shows that the new 3D design approach and its manufacturing system was found easy and precise to generate the different multi-layer panels pattern for developing seamless female soft body armour.
In this paper, we develop mixed-integer linear programming models for assigning the most appropriate teaching assistants to the tutorials in a department. The objective is to maximize the number of tutorials that are taught by the most suitable teaching assistants, accounting for the fact that different teaching assistants have different capabilities and each teaching assistant's teaching load cannot exceed a maximum value. Moreover, with optimization models, the teaching load allocation, a time-consuming process, does not need to be carried out in a manual manner. We have further presented a number of extensions that capture more practical considerations. Extensive numerical experiments show that the optimization models can be solved by an off-the-shelf solver and used by departments in universities.
OBJECTIVES: To demonstrate the impact of health consequences feedback on patients willingness to accept advice about drinking. METHODS: 281 patients identified as hazardous drinkers were offered advice about alcohol consumption. During the experimental period patients' were given feedback as to the health consequences. RESULTS: Introduction of feedback led to a 23% increase in the proportion of patients who were willing to accept brief advice. CONCLUSIONS: Feedback provision should be included as part of Screening and Brief intervention programmes to increase the number of patients that may benefit from an intervention.
thyssenkrupp Elevator ensures mobility at fashionable new city block, Urban Escape, in Stockholm and thus contributes to making urban transportation more efficient, comfortable and secure. The highly-anticipated site marks the biggest ever contract for thyssenkrupp Elevator in Sweden. Work commenced in 2015, all elevators were installed last month and tenants are welcome to move in from March onwards.
Proteinase-activated receptor 2 (PAR(2)) is a G-protein-coupled receptor for trypsin and mast cell tryptase; it is highly expressed at the intestinal level with multiple functions, such as epithelial permeability and intestinal motility. The aim of the study was to evaluate the distribution and expression of proteinase-activated receptor 2 in the small intestine during herniation through epiploic foramen. In this prospective clinical study, eight horses admitted for colic and which underwent exploratory laparotomy were considered. During surgery, the jejunum or the ileum was sampled by enterectomy. Morphological examination (histology, PAR(2) immunohistochemistry) and molecular biology analysis (western blot and quantitative polymerase chain reaction) were carried out on the resected intestinal samples. The Marginal Injured Tracts (MITs) and Central Injury Tracts (CITs) were defined as the oral and caudal marginal segments of the resected bowel tract and as the geometric centre of the intestinal ischaemic lesion length, respectively.
