Radioprotective effects of the water-soluble polyphenolic glycoconjugates, isolated from flowers of Sanguisorba officinalis L.(SO) and Erigeron canadensis L.(EC), and from leaves of Fragaria vesca L. (FV) and Rubus plicatus Whe. Et N. E. (RP), against γ-radiation-induced toxicity in human peripheral blood lymphocytes were investigated. Cell treatment with glycoconjugates (1, 5, 25μg/ml) prior exposure to 10/15Gy radiation resulted in concentration-dependent reduction of DNA damage including oxidative DNA lesions (comet assay), substantial inhibition of lipid peroxidation (TBARS) and restoration of superoxide dismutase and S-glutathione transferase activities...

Spider dragline is used by many members of the Araneae family not only as a proteinogenic safety thread but also for web construction. Spider dragline has been shown to possess high tensile strength in combination with elastic behavior. This high tensile strength can be attributed to the presence of antiparallel β-sheets within the thread; these antiparallel β-sheets are why the protein is classified as a silk. Due to the properties of spider silk and its technical and medical uses, including its use as a suture material and as a scaffold for tissue regeneration, spider dragline is a focus of the biotechnology industry...

The treatment of Bell's palsy (BP), based on steroids and/or antiviral drugs, may still leave a certain percentage of affected subjects with disfiguring sequelae due to incomplete recovery. The different procedures of physical rehabilitation have not been demonstrated to play a favourable role in this disorder. The aim of the present study was to compare functional outcomes in severe cases of Bell's palsy when treated by steroids alone or by steroids accompanied by Kabat physical rehabilitation. This prospective study included 94 subjects who showed sudden facial nerve (FN) palsy with House-Brackmann grade IV or V and who were divided into two groups on the basis of the therapeutic approach: one group (a) was treated by steroids, and the other (b) received steroids in combination with physical rehabilitation...

BACKGROUND: To test if complexity of acetabular fractures, pre-trauma health status, time from trauma to definitive surgery, severity of injury or job characteristics influence work resumption, return to the same professional position and time out of work. MATERIALS AND METHODS: We performed a retrospective study on patients with surgically treated acetabular fractures. Medical records were reviewed to analyse demographics, follow-up, diagnosis (Letournel classification), type of surgical treatment, co-morbidities, time from trauma to definitive surgery, American Society of Anesthesiologists physical status classification (ASA) and associated injuries...

AIM: To assess correlations between the characteristics of the nursing practice environment, job outcomes and safety climate. BACKGROUND: The nursing practice environment is critical to the well-being of professionals and to patient safety, as highlighted by national and international studies; however, there is a lack of evidence regarding this theme in paediatric units. METHODS: A cross-sectional study, in two paediatric hospitals in Brazil, was conducted from December 2013 to February 2014...

Strong evidence for the statistical association between radiation exposure and disease has been produced for thyroid cancer by epidemiological studies after the Chernobyl accident. However limitations of the epidemiological approach in order to explore health risks especially at low doses of radiation appear obvious. Statistical fluctuations due to small case numbers dominate the uncertainty of risk estimates. Molecular radiation markers have been searched extensively to separate radiation- induced cancer cases from sporadic cases...

Immune thrombocytopenia purpura (ITP) is characterized by the production of pathological autoantibodies that cause reduction in platelet counts. The disease can have serious medical consequences, leading to uncontrolled bleeding that can be fatal. Current widely used therapies for the treatment of ITP are non-specific and can, at times, result in complications that are more burdensome than the disease itself. In the present study, the use of platelet membrane-coated nanoparticles (PNPs) as a platform for the specific clearance of anti-platelet antibodies is explored...

Statistical models to predict incident diabetes are often based on limited variables. Here we pursued two main goals: 1) investigate the relative performance of a machine learning method such as Random Forests (RF) for detecting incident diabetes in a high-dimensional setting defined by a large set of observational data, and 2) uncover potential predictors of diabetes. The Jackson Heart Study collected data at baseline and in two follow-up visits from 5,301 African Americans. We excluded those with baseline diabetes and no follow-up, leaving 3,633 individuals for analyses...

In-vivo estimates of the positions of knee ligament attachment sites are crucial for subject-specific knee modelling. The present study provides template digital models of femur, tibia and fibula that embed the positions of centroids of the origins and insertions of cruciate and collateral ligaments, along with information on their dispersion related to inter-individual variability. By using a shape transformation procedure of choice, these templates can be made to match anatomical information measured on a subject under analysis...

Background: We investigated and evaluated the cost effectiveness of coding by health care economists in a centre for orthopaedics and trauma surgery in Germany, by quantifying and comparing the financial efficiency of physicians with basic knowledge of the DRG-system with the results of healthcare economists with in-depth knowledge (M.Sc.). In addition, a hospital survey was performed to establish how DRG-coding is being performed and the identity of the persons involved. Material and Methods: In a prospective and controlled study, 200 in-patients were coded by a healthcare economist (study group)...

BACKGROUND: There is a paucity of information regarding institutional targets for the number of undergraduate medical education (UME) graduates being matched to graduate medical education (GME) programs at their home institutions. At our institution, the Duke University, the number of UME graduates matched to GME programs declined dramatically in 2011. To better understand why this decline may have happened, we sought to identify perceived quality metrics for UME and GME learners, evaluate trends in match outcomes and educational program characteristics, and explore whether there is an ideal retention rate for UME graduates in their home institutions' GME programs...
