Non-operative management of blunt abdominal trauma. Is it safe and feasible in a district general hospital?
<p>Abstract</p> <p>Background</p> <p>To evaluate the feasibility and safety of non-operative management (NOM) of blunt abdominal trauma in a district general hospital with middle volume trauma case load.</p> <p>Methods</p> <p>Prospective protocol-driven study including 30 consecutive patients who have been treated in our Department during a 30-month-period. Demographic, medical and trauma characteristics, type of treatment and outcome were examined. Patients were divided in 3 groups: those who underwent immediate laparotomy (OP group), those who had a successful NOM (NOM-S group) and those with a NOM failure (NOM-F group).</p> <p>Results</p> <p>NOM was applied in 73.3% (22 patients) of all blunt abdominal injuries with a failure rate of 13.6% (3 patients). Injury severity score (ISS), admission hematocrit, hemodynamic status and need for transfusion were significantly different between NOM and OP group. NOM failure occurred mainly in patients with splenic trauma.</p> <p>Conclusion</p> <p>According to our experience, the hemodynamically stable or easily stabilized trauma patient can be admitted in a non-ICU ward with the provision of close monitoring. Splenic injury, especially with multiple-site free intra-abdominal fluid in abdominal computed tomography, carries a high risk for NOM failure. In this series, the main criterion for a laparotomy in a NOM patient was hemodynamic deterioration after a second rapid fluid load.</p
Angiomyofibroblastoma of the spermatic cord: a case report
<p>Abstract</p> <p>Introduction</p> <p>Angiomyofibroblastoma is a benign soft tissue tumor with tendency to arise in the vulva.</p> <p>Case presentation</p> <p>We report a 36-year-old Greek Caucasian man presenting with a left inguinal painless mass. This is the second case of angiomyofibroblastoma of the spermatic cord. At operation, a 4.5 cm well-circumscribed solid tumor was found adherent to the spermatic cord. The tumor consisted of spindle-shaped cells proliferating in short fascicles between numerous medium-sized blood vessels with thin and hyalinized walls. Neoplastic cells had eosinophilic cytoplasm with neither mitotic figures nor nuclear atypia. The stroma included abundant mast cells and few mature lypocytes. Immunostaining showed positivity for vimentin, CD34, desmin and smooth muscle actin. Our patient was treated by simple excision and was followed up for five years with clinical examination and ultrasonography, revealing no evidence of local recurrence or metastasis.</p> <p>Conclusion</p> <p>This unusual neoplasm should be distinguished from aggressive angiomyxoma and other myxoid malignant tumors with widespread metastatic potential.</p
Towards a European ITS for freight transport and logistics: results of current EU funded research and prospects for the future

Accurate microRNA target prediction correlates with protein repression levels
MicroRNAs are small endogenously expressed non-coding RNA molecules that regulate target gene expression through translation repression or messenger RNA degradation. MicroRNA regulation is performed through pairing of the microRNA to sites in the messenger RNA of protein coding genes. Since experimental identification of miRNA target genes poses difficulties, computational microRNA target prediction is one of the key means in deciphering the role of microRNAs in development and diseas
Immune Cell Recruitment and Cell-Based System for Cancer Therapy
Immune cells, such as cytotoxic T lymphocytes, natural killer cells, B cells, and dendritic cells, have a central role in cancer immunotherapy. Conventional studies of cancer immunotherapy have focused mainly on the search for an efficient means to prime/activate tumor-associated antigen-specific immunity. A systematic understanding of the molecular basis of the trafficking and biodistribution of immune cells, however, is important for the development of more efficacious cancer immunotherapies. It is well established that the basis and premise of immunotherapy is the accumulation of effective immune cells in tumor tissues. Therefore, it is crucial to control the distribution of immune cells to optimize cancer immunotherapy. Recent characterization of various chemokines and chemokine receptors in the immune system has increased our knowledge of the regulatory mechanisms of the immune response and tolerance based on immune cell localization. Here, we review the immune cell recruitment and cell-based systems that can potentially control the systemic pharmacokinetics of immune cells and, in particular, focus on cell migrating molecules, i.e., chemokines, and their receptors, and their use in cancer immunotherapy

Robust estimation of bacterial cell count from optical density
Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data
ISSUES OF THE EUROPEAN AN TRANSPORT POLICY AND CURRENT STATE OF EU FUNDED TRANSPORT RESEARCH RES
Abstract: This paper sets out the main lines of the existing EU Transport Policy, and transport research. After a brief description of the main elements of this policy, a discussion is given of its relation with transport research and the basic orientations that existed under the previous Framework Programmes for EU funded research. Then the main elements of the policy for the new (6th) Framework Program are presented

Towards a Common Surface Transport Policy for South East Europe
This paper addresses the all-important issue of forming a common transport policy for South East European countries with primary objective this of the re-balancing the future traffic flows towards more use of rail and maritime transport (including inland waterways). First, the elements of the new EU transport policy that address this issue are mentioned. Then, the paper examines in detail the specific factors that apply in the region of South East Europe and which may alter or influence the expected results of the application of these factors. The factors examined are the following: improving the infrastructure of the railways, various measures of promoting transport by sea and inland waterways, turning “intermodality” into reality, building the trans-European transport networks, adopting a common policy for charging for transport, utilizing research and innovation technology, implementing medium and long-term transport related environmental objectives, implementing transport-related “soft” measures. The last section of the paper examines in more detail the status and prospects of improvement of two major rail axes in the area, the axes nr. X and nr. IX. This is given as an example of the kind of actions needed to improve rail infrastructure and the involved substantial efforts that are necessary.
