Published: December 2014

Introduction The purpose of this study was to evaluate the evolution of the mechanical properties of stretchable and non-stretchable ePTFE vascular grafts over time following implantation, as well as those of the adjacent native vessels. Methods One stretchable and one non-stretchable graft were implanted in either carotid position of six sheep. After twelve weeks, the samples, as well as the distal adjacent native vessel, were explanted and evaluated mechanically by means of uniaxial tensile tests. These tests were performed in the axial as well as in the circumferential direction. Also, patches of these grafts were implanted subcutaneously in the abdominal wall of the same animals. At 2, 4, 6, and 8 weeks, patches were explanted and evaluated mechanically. Baseline mechanical tensile tests were also performed on non-implanted grafts and on native sheep carotid arteries. Results Statistical analysis shows a significant effect of implantation time on the tensile mechanical properties of ePTFE vascular grafts. This effect is present for stretchable as well as non-stretchable grafts, in axial as well as in circumferential direction of the material. Also the adjacent native vessels have a tendency to lose mechanical stiffness and strength in the circumferential direction, an effect which is most pronounced for stretchable grafts. Conclusions The mechanical properties of ePTFE vascular grafts and the adjacent native vessels significantly change as a function of implantation time. Compared to the native vessels, the grafts are still significantly stronger and stiffer, though longer term experiments are needed to evaluate whether and how much the decline would continue in time.

Purpose We evaluate the effect of the protoconized anemia therapy on adverse events using the Hb and ferritin levels of individual patients undergoing maintenance hemodialysis (MHD). Methods Design: A randomized, parallel group, multi-center study. Patients Two hundred sixty-six MHD patients. Intervention group: The doses of erythropoietin, iron, and vitamin C were adjusted every month based on the ferritin and hemoglobin (Hb) levels according to the protocol. Non-intervention group: The attending physician determined the doses of erythropoietin and iron. Results The maintenance rate of target Hb and ferritin levels were significantly higher in the Intervention group than in the Non-intervention group. The frequency of hospitalization was significantly lower for patients with a higher maintenance rate of target Hb levels than for those with a lower maintenance rate. Conclusions Using an anemia treatment protocol according to the individual Hb and ferritin levels of hemodialysis patients might stabilize the Hb and ferritin levels, which in turn could contribute to the lower frequency of adverse events in MHD patients.

See video of the presentation.Theory and Practice in OA-policies: The Research Council of Norway is currently revising its policy on Open Access. At the same time the Council is looking at ways to support Norwegian journals within humanities and social sciences in order to promote OA-publishing. As a funding agency, the Research Council is looking at ways to implement OA-policies. The key question is: How to move from principle declarations on Open Access to practical tools for achieving OA-goals? Schjølberg and Løvhaug will present a model for financial support to OA-journals within humanities and social sciences as a joint venture between the Research Council and research institutions in Norway.
Better than Average – The Positive Effects of a Department actively supporting Open Access
Authors: Kullman Lars , Gilbert Jonas 
Published: December 2014

Chalmers University of Technology adopted an Open Access policy in 2010, mandating its researchers to deposit copies of their work in the university repository (Chalmers Publication Library). The Library was given the assignment to implement the policy but also to monitor the progress. In the beginning of 2013 we compiled the first comprehensive report to the university management and the departments.The share of Open Access publications varies to a large degree between different departments and subject fields. The reaction from the departments when presented to the numbers also varies, from referring to ‘the usual suspects’ – workflow issues, copyright issues, didn’t remember etc – to the reaction: how can we improve us?The Department of Signals and Systems publishes approx. 100 peer-reviewed journal articles and 200 peer-reviewed conference papers yearly. The Department started an active discussion how to improve the rate of Open Access. This discussion resulted in a project together with the library, in order to increase the number of Open Access publications and the visibility of the researchers and their publications on the web. The aim was to bring the share of Open Access publications from about 30 % to 100 %. An agreement with the Library was signed, where the library would assist the researchers to submit their papers to the repository. The proposed poster will discuss:a) How we provide feedback to management and departments.b) The differences between departments when it comes to Open Access publications.c) The importance of a department management actively promoting Open Access.d) How library and department collaborates in order to increase the amount of Open Access publications.e) Outcome and lessons learned from such collaboration.We hope to contribute to and participate in the discussion on what best practice the library should adopt to evaluate the progress of the transition to an open access culture among researchers.

Jetty Port (Parola Wharf) in Iloilo City is a depot of passengers going toGuimaras, Philippines. Considering the dearth of studies on the presence of heavymetals in this area, this study was conducted. It aimed to determine the presenceand quantities of available heavy metals specifically lead, cadmium and chromiumin the water column (surface, middle and bottom) of Iloilo-Guimaras Jetty Port. Inaddition, water physicochemical parameters were also measured such as pH, salinityand temperature, in situ. Three sampling areas were identified in the Jetty Port.One liter was collected in the surface, middle and bottom layer of each sampling area for a total of nine seawater samples. The seawater samples were immediatelytransported to the CAS-Analytical Service Laboratory of UPV, Miag-ao, Iloilofor the quantification of available heavy metals through flame atomic absorptionspectrophotometric (FAAS) method. Ph values range from 6.0-7.333, 12.0-13.167ppm for salinity and 27.333-27.567 0C for three sampling areas. Average cadmium,chromium and lead were higher at station 3 with 0.69 mg/L, 0.81 mg/L and 0.339mg/L, respectively. The results showed that mean of Cr > Pb > Cd < Cr in the watercolumn of the three sampling areas, however is not significant, p>.05. Availablecadmium, chromium and lead exceeded the permissive value. This study will giveinformation to the public about the present heavy metal status of the Jetty Port.

Abstract
The purpose of this study was to evaluate the success and morbidity of percutaneous nephrolithotomy (PCNL) performed through the 11th and 10th intercostal space. Between March 2005 and February 2012, 612 patients underwent PCNL, 243 of whom had a supracostal access. The interspace between the 11th and 12th rib was used in 204 cases (group 1) and between the 10th and 11th interspaces in 39 cases (group 2). PCNL was performed using standard supracostal technique in all patients. The operative time, success rate, hospital stay, and complications according to the modified Clavien classification were compared between group 1 and group 2. The stone-free rate was 86.8% in group 1 and 84.6% in group 2 after one session of PCNL. Auxiliary procedures consisting of ureterorenoscopy (URS) and shock wave lithotripsy (SWL) were required in 5 and 7 patients, respectively, in group 1; and in 1 patient each in group 2 . After the auxiliary procedures, stone-free rates increased to 92.6% in group 1 and 89.7% in group 2. A total of 74 (30.4%) complications were documented in the 2 groups according to modified Clavien classification. Grade-I complications were recorded in 20 (8.2%), grade-II in 38 (15.6%), grade-IIIa in 13 (5.3%), and grade-IIIb in 2 (0.8%) patients; grade-IVa was recorded in 1 (0.4%) patient. There were no grade-IVb or grade-V complications. Overall complication rate was 30.9% in group 1 and 28.2% in group 2. Supracostal PCNL in selected cases is effective and safe with acceptable complications. The modified Clavien system provides a standardized grading system for complications of PCNL.

Published: December 2014

Abstract
This trial was designed to compare the efficacy of 4% chlorhexidine gluconate (CHG) with normal saline (NS) as a predisinfection skin-scrub solution prior to standard presurgical skin preparation. Data was collected at a single transplantation center where patients electing resection of hepatic tumors were recruited between October 2011 and September 2012. In total, 100 patients were consecutively enrolled for random assignment to either 4% CHG or NS as a predisinfection skin-scrub solution prior to surgery. Our aim was to assess the comparative antiseptic efficacy of CHG in this setting, focusing on cutaneous microbial colonization (at baseline, preoperatively, and postoperatively) and postsurgical site infections as primary outcome measures. Positivity rates of baseline, preoperative, and postoperative cultures were similar for both groups, showing significant declines (relative to baseline) after skin preparation and no significant postsurgical rebound. Rates of surgical site infection were also similar in both groups (CHG, 6.0%; NS, 4.1%; P = 1.0). For patients with hepatic tumors undergoing hepatectomy, the effect of 4% CHG as a predisinfection scrub solution was similar to that of NS in terms of skin decontamination and surgical site infections.

Published: December 2014

Abstract
Among many techniques independently reported to manage neuroma formation, manipulation of the nerve stump inside muscle and vein is the most advantageous technique. This study aimed to enrich the basic data of macroscopic appearance and histo-pathology regarding which technique generates less neuroma: nerve stump implantation inside vein or inside muscle. An experimental study with posttest-only control-group design was conducted in 24 rats that were randomly arranged into 3 groups. One centimeter of the lateral branch of the right ischiadic nerve was cut. Group A served as the control group, where the proximal nerve stumps were left as they were after the excision; whereas the stumps of groups B and C were implanted inside muscles and veins, respectively. The samples were assessed with histologic examination after 4 weeks to measure the morphometric changes in the nerve endings. The data were statistically analyzed with t test. All rats healed uneventfully. No thrombosis was found within group C, and the stumps were free of neuroma formation. The muscle group formed smaller neuroma than the control group. Statistical analysis showed significant differences between the groups (P &lt; 0.05). The outcome of nerve stump implantation inside the lumen of a vein is superior to the implantation inside a muscle in preventing neuroma formation.

Published: December 2014

Abstract
Single-port laparoscopic cholecystectomy (LC) has been compared with 3- or 4-port LC. To our knowledge, there are no studies comparing the 3-, 2-, and 1-port techniques. Patients were randomized into 3 groups: LC 1-port using SILS, LC 2-port using a laparoscope with a working channel, and LC 3-port using the standard ports. Pain was evaluated at recovery, 4 hours, 24 hours, day 5, and day 8, using an analog visual scale. Homogenous groups in their demographic characteristics; all confirmed gallbladder lithiasis. At recovery, there was less pain in group 1 (P = 0.002); at 4 hours pain was similar in all groups (P = 0.899); at 24 hours there was less pain in groups 2 and 3 (P = 0.031); and at days 5 and 8 there was marginal (P = 0.053) and significant (P = 0.003) relevance. In terms of pain perception, LC performed through 1 port does not offer advantages when compared with 2 or 3 ports. More clinical trials are needed to confirm these data.

AbstractHepatic ischemia reperfusion (IR) injury has complex mechanisms. We investigated the effect of dexketoprofen on endogenous leptin and malondialdehyde (MDA) levels. Wistar albino rats were divided into 4 equal groups and were subjected to 1-hour ischemia and different subsequent reperfusion intervals. Dexketoprofen was administered in a dose of 25 mg/kg 15 minutes before ischemia induction and 1-hour reperfusion to the Dexketoprofen one-hour reperfusion group, n = 6 (DIR1) group and 6-hour reperfusion to the Dexketoprofen six-hour reperfusion group, n = 6 (DIR6) group. In the control groups, 0.9% physiologic serum (SF) was administered 15 minutes before ischemia induction and 1-hour reperfusion to the one-hour reperfusion group, n = 6 (IR1) group and 6-hour reperfusion to the six-hour reperfusion group, n = 6 (IR6) group. Although serum leptin (P = 0.044) and hepatic tissue MDA levels (P = 0.004) were significantly higher in the IR6 group than in the IR1 group, there were no significant differences in dexketoprofen pretreatment between the DIR1 and DIR6 groups. There were no differences in serum MDA levels among the 4 groups, and serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities were significantly higher in the IR1 (P = 0.026 and P = 0.018, respectively) and IR6 (P = 0.000 and P = 0.002, respectively) groups than in the DIR1 and DIR6 groups. Dexketoprofen pretreatment can protect the liver from IR injury by decreasing inflammation and lipid peroxidation. Our study shows that dexketoprofen has no effects on endogenous leptin during IR injury.
Working Covers
Authors: Patrik Gary 
Published: December 2014

Abstract
A working cover is a very standard and prevalent form of excess‐of‐loss treaty reinsurance. Working covers provide capacity and stabilization for a ceding company's financial results. A working cover provides capacity because it allows the ceding company to write higher policy limits and yet maintain a manageable risk level. Working covers enhance competition within the insurance marketplace by providing a means by which smaller insurers can compete with larger insurers. Working covers are often large enough so that many of the pricing parameters can be estimated either directly from the exposure and claims history or by a credibility weighting of that history with more general industry information.
The role of kinship in the formation of a primate multilevel society

Published: December 2014

ABSTRACTA small number of mammalian species live in a modular or multilevel society in which several individual social/reproductive units called one‐male units (OMUs) are embedded within a large cohesive band. Factors that affect band composition and stability are poorly understood. In this study we examined the role of kinship in the formation and maintenance of a multilevel society in an endangered population of golden snub‐nosed monkeys (Rhinopithecus roxellana). From 2005 to 2011, we obtained genetic samples from 86 individuals (including 88.9% of leader males and 80.5% of adult females) living in a band of 8–10 OMUs. We used microsatellite genotyping to identify patterns of relatedness and individual transfer. We found that adult females residing in the same OMU were more closely related to each other than to a random set of females drawn from the band and that females tended to disperse into OMUs that contained female relatives. In addition, adult females who transferred were not more closely related to their previous leader male than to the leader male of their new OMU. These results support the contention that kin bonds contribute importantly to the formation and stability of this primate multilevel society by influencing a female's decision to remain in her current OMU, or during transfer, which new OMU to enter.

Photocaged DNAzymes as a General Method for Sensing Metal Ions in Living Cells

Published: December 2014

AbstractDNAzymes, which are sequences of DNA with catalytic activity, have been demonstrated as a potential platform for sensing a wide range of metal ions. Despite their significant promise, cellular sensing using DNAzymes has however been difficult, mainly because of the “always‐on” mode of first‐generation DNAzyme sensors. To overcome this limitation, a photoactivatable (or photocaged) DNAzyme was designed and synthesized, and its application in sensing ZnII in living cells was demonstrated. In this design, the adenosine ribonucleotide at the scissile position of the 8–17 DNAzyme was replaced by 2′‐O‐nitrobenzyl adenosine, rendering the DNAzyme inactive and thus allowing its delivery into cells intact, protected from nonspecific degradation within cells. Irradiation at 365 nm restored DNAzyme activity, thus allowing the temporal control over the sensing activity of the DNAzyme for metal ions. The same strategy was also applied to the GR‐5 DNAzyme for the detection of PbII, thus demonstrating the possible scope of the method.
Multiperiodic semiregular variable stars in the ASAS data base: A pilot study
Authors: Fuentes‐Morales I. , Vogt N. 
Published: December 2014

AbstractBased on a search for multi‐periodic variability among the semi‐regular red variable stars in the database of the All Sky Automated Survey (ASAS), a sample of 72 typical examples is presented. Their period analysis was performed using the Discrete Fourier Transform. In 41 stars we identified two significant periods each, simultaneously present, while the remaining 31 cases revealed even three such periods per star. They occur in a range roughly between 50 and 3000 days. Inter‐relationships between these periods were analyzed using the “double period diagram” which compares adjacent periods, and the so‐called “Petersen diagram”, the period ratio vs. the shorter period. In both diagrams we could identify six sequences of accumulation of the period values. For five of these sequences (containing 97 % of all data points) we found an almost perfect coincidence with those of previous studies which were based on very different samples of semiregular red variables. Therefore, existence and locations of these sequences in the diagrams seem to be universal features, which appear in any data set of semi‐regularly variable red giants of the AGB; we conclude that they are caused by different pulsation modes as the typical and consistent properties of similar stellar AGB configurations. Stellar pulsations can be considered as the principal cause of the observed periodic variability of these stars, and not binary, rotation of a spotted surface or other possible reasons suggested in the literature.

What SDO tells us about structure and evolution of coronal bright points

Published: December 2014

AbstractUsing magnetograms and coronal images from two instruments on board the Solar Dynamics Observatory (SDO), we study structure and evolution of a limited number of coronal bright points (CBPs). Our results show that the relation between CBPs and their magnetic footpoints is not simple. In some cases, CBP may appear as a bright portion of a larger loop (with clearly identifiable footpoints), and in some cases, an isolated CBP may develop between magnetic poles, which might not be the closest ones to each other or which might not be involved in the magnetic flux cancellation. We suggest that the magnetic connectivity responsible for formation of isolated coronal bright points is governed by the orientation of the large‐scale magnetic field.
