Where She Comes From: Locating Queer Transracial Adoption
Authors: Romesburg Don 
Published: October 2014

Abstract
This article attempts to answer the oft-asked question of where my daughter—an African American girl with two white, middle-class gay dads—“comes from,” by tracing power constellations that make our family possible. Through critical autoethnography, it interweaves narrative about the evolving relationship we share with her birth family with analysis of intersecting, conflicting histories of U.S. transracial adoption, same-sex family recognition, shrinking public support systems for and growing criminalization of low-income women and families of color, gendered dynamics in parenting, and the shift toward foster-adoption permanency. Utilizing queer, feminist, and critical race theories of kinship, I advocate for “queer transracial family” as a form of differential becoming that is attentive to complex power relations. Queer transracial family as a critical practice seeks to enact a blended, open vision for belonging that contests colorblindness, homonormativity, and the consumerist, privatized family.
Efficacy of routine diabetic foot treatments at an outpatient clinic: a cohort study
Authors: Udovichenko Oleg Viktorovich , Berseneva Eugenia Alexandrovna 
Published: October 2014

Reliable data on the efficacy of treatment for diabetic foot (DF) ulcers (DFUs) is essential for planning outpatient services, comparison of several DF clinics, pharmacoeconomic studies and prognosis of healing time. However, no reports based on Russian DF cases have been published to date.Aim. The aim of our study was to analyse of the outcomes of routine DFU treatments at one DF outpatient clinic (DFOC).Materials and methods. We analysed the medical records of all patients admitted to one DFOC for foot/leg ulcers in 2012 (72 patients, 77 episodes of treatment, 124 ulcers in total). The median age of the patients was 66 years (range: 45?90 years), 51% patients were females and 49% were males. Three (4%) patients had type 1 diabetes mellitus, whereas the rest had type 2 diabetes mellitus. The median duration of ulcer prior to the initiation of treatment was 31 days (range: 1?392 days). A total of 106 (85%) cases involved DFUs, whereas 18 (15%) involved leg ulcers in patients with diabetes. One patient had a combination of foot and leg ulcers. Examination and treatment of all patients were conducted by a single experienced doctor according to international and national guidelines. The follow-up time ranged from 8?20 months.Results. Lower extremity ischemia was observed in 39% cases. The healing rate for all ulcers at 3, 6 and 12 months was 34%, 51% and 65%, respectively. At follow-up time, ulcers remained unhealed in 16% patients and 9% survived amputations [1 (1%), below knee; 6 (8%), minor)]. Furthermore, 4% patients died on account of cardiovascular events. The results of the present study were comparable to those reported in other countries. Modern and effective treatment modalities (such as contact casting and revascularisation) were not used extensively; therefore, their active utilisation is necessary to improve treatment outcomes.Conclusions.

The healing rate for ulcers in our cohort was 34%, 51% and 65% at 3, 6 and 12 months, respectively.
Treatment efficacy should be improved by increasing the use of total contact casting and revascularisation.
Person-related measures (i.e. healing of all ulcers in a patient) are optimal for most cases, although ulcer-related measures can be significant in cases where several ulcers are detected in a patient.
Our studied cohort is typical for a DFOC; therefore, our data can be used for planning outpatient services, evaluation of other DFOCs and pharmacoeconomic studies.

Genetic susceptibility plays an important role in the risk of developing chronic complications in patients with type 2 diabetes mellitus (T2DM). Aims. In this study, we evaluated the possible association of the polymorphic variants that encode key renal damage mediators (endothelial dysfunction, lipid metabolism and insulin secretion/sensitivity) with the risk of chronic kidney disease (CKD) in patients with T2DM. Materials and Methods. We enrolled 435 patients with T2DM using case-control study design. In 253 patients, we used non-overlapping criteria to form groups with/without CKD (defined as GFR=10 years) (n=75 and 178, respectively) and analysed the following 4 polymorphic markers: I/D in ACE, ecNOS4a/4b in NOS3, I/D in APOB and e2/e3/e4 in APOE genes. We then divided 182 patients in groups with/without CKD (n=38 and 144, respectively) regardless of the duration of diabetes and studied pro12ala in PPARG2, rs5219 in KCNJ11, rs12255372 in TCF7L2 and rs13266634 in SLC30A8 genes. 2 test, and data were expressed as odds ratios (ORs) with 95% confidence intervals (CIs).

Price-level instability and international monetary policy coordination
Authors: Nguyen Hong Thang 
Published: October 2014

AbstractIn a two-country open economy model, Bencivenga, Huybens, and Smith [2002, What to Stabilize in the Open Economy, International Economic Review 43, 1289–1307] investigate three policy regimes and find that a fixed exchange rate regime, where the country with the lowest reserve-to-deposit ratio is charged with maintaining the fixed rate, and a price-level targeting regime are both more prone to price-level instability than a constant money growth rate regime. This paper, by replacing their “helicopter drops” assumption with an open market operations assumption, shows that the two rules of fixing the money growth rate and targeting the time path of the price level work equally well. Additionally, under a regime of fixed exchange rates, it does not matter which country is charged with keeping the fixed exchange rate.
Characterization of auxetic polyurethanes foam for biomedical implants
Authors: Bhullar Sukhwinder K. 
Published: October 2014

AbstractAging, accidents and diseases are the leading causes of disability in today’s world. Therefore, implants and prostheses for hard and soft tissues are becoming increasingly common to restore daily activity and improve the quality of life of patients. Although implants have been extensively developed and are in the clinical use, deformation mechanism, inflexibility and mismatch of the elastic and mechanical behavior of the implants with native tissues are challenges for tissue engineering. The objective of this study was to characterize auxetic polyurethane foam as an auxetic soft tissue implant based on mathematical modeling using a nonlinear elasticity theory. The compressibility effects on auxetic soft tissue implants due to equibiaxial loading were studied. Numerical results were computed using experimentally obtained data and compared with the non-auxetic behavior of a soft tissue.
Green synthesis of dual-surface nanocomposite films using Tollen’s method
Authors: Badawy Sayed M. 
Published: October 2014

Abstract
Nanocomposite films with dual-surface, silver (Ag) layers and silver-polyvinyl alcohol (Ag-PVA) bulk layers were prepared by Tollen’s reagent using β-D-glucose as a green reducing agent in water as an environmentally-friendly solvent and in PVA as a bio-friendly polymer. The gradual color change of Ag in PVA solutions from colorless to light brown and then to brown, and finally dark brown, indicated the formation of Ag nanoparticles in the bulk of the PVA solution which finally formed Ag layers on the inner side of the glass. Energy dispersive X-ray (EDX) analysis and X-ray diffraction (XRD) were used to characterize the nanocomposite films with two surfaces. The Ag content of the Ag layers reached 93% with a higher crystallinity. The Ag content of the Ag-PVA bulk layers reached 10.8% with a lower crystallinity due to incorporation of Ag nanoparticles in the polymer chains. The structure and morphology of the two surfaces were confirmed by scanning electron microscopy (SEM).
Attenuating effect of standardized lyophilized Cinnamomum zeylanicum bark extract against streptozotocin-induced experimental dementia of Alzheimer’s type

Published: October 2014

Abstract

Background: The Cinnamomum zeylanicum (CZ; family Lauraceae) bark, an important spice, has also been used traditionally for nervous stress, as a nervine tonic, and as a stimulant. Therefore, the present study was designed to evaluate the effect of the standardized lyophilized aqueous extract of CZ bark (LCZE) on learning and memory in rodents at 50, 100, and 200 mg/kg, p.o. dose levels against streptozotocin (STZ)-induced memory impairment.

Methods: LCZE was standardized based on the cinnamaldehyde content using high-performance thin-layer chromatography (HPTLC). The effect on learning and memory was evaluated using two widely used behavioral models, the Morris water maze (MWM) test and the object recognition test (ORT). The effect of LCZE on the acetylcholinesterase (AChE) activity and oxidative stress parameters in the cerebral cortex and hippocampus of rat brain was also evaluated.

Results: LCZE significantly (p<0.05) and dose-dependently attenuated STZ-induced cognitive deficit in both models in comparison to only STZ-treated animals. In the MWM test, LCZE (100 and 200 mg/kg) significantly decreased the transfer latency and increased the time spent by the animals in target quadrant. Similarly in the ORT, the LCZE-treated animals exhibited an improved discrimination between a familiar object and a novel object, indicating the reversal of STZ-induced memory impairment. LCZE also restored STZ-induced alteration in AChE activity and oxidative stress parameters in both brain parts.

Conclusions: The results clearly indicate toward the memory-enhancing effect of LCZE, which could be due to the synergistic effect of anti-AChE and antioxidant activities.

Abstract
In [J. Algebra 344 (2011), 205–228], a conjecture of J. G. Thompson for PSL
n
(q) was proved. It was shown that every finite group G with the property Z(G) = 1 and cs(G) = cs(PSL
n
(q))
is isomorphic to PSL
n
(q) where cs(G) is the set of conjugacy class sizes of G. In this article we improve this result for PSL2(q). In fact we prove that if cs(G) = cs(PSL2(q)),
for q > 3, then G ≅ PSL2(q) × A, where A is abelian. Our proof does not depend on the classification of finite simple groups.
Free vibration and postbuckling of laminated composite Timoshenko beams
Authors: Ansari Reza , Shojaei Mostafa Faghih , Mohammadi Vahid , Rouhi Hessam 
Published: October 2014

Abstract
A numerical solution method was developed to investigate the postbuckling behavior and vibrations around the buckled configurations of symmetrically and unsymmetrically laminated composite Timoshenko beams subject to different boundary conditions. The Hamilton principle was employed to derive the governing equations and corresponding boundary conditions which are then discretized by introducing a set of matrix differential operators. The pseudo-arc-length continuation method was used to solve the postbuckling problem. To study the free vibration that takes place around the buckled configurations, the corresponding eigenvalue problem was solved by means of the postbuckling configuration modes obtained in the previous step. The static bifurcation diagrams for composite beams with different lay-up laminates are given, and it is shown that the lay-up configuration considerably affects the magnitude of critical buckling load and postbuckling behavior. The study of the vibrations of composite beams with different laminations around the buckled configurations indicates that the natural frequency in the prebuckling domain increases as the stiffness of a beam increases, while there is no specific relation between the lay-up lamination and natural frequency in the postbuckling domain which necessitates conducting an accurate analysis in this area.

Authors: Christau Stephanie , Genzer Jan , von Klitzing Regine 
Published: October 2014

Abstract
This review article summarizes the progress of research in the field
of polymer brush/metal nanoparticle hybrid materials. We will
discuss the mutual influence of polymer brush matrix and
particles. Self-assembly of particles within polymer brushes, and ways
to control the loading and location of nanoparticles inside polymer
brushes will be described, as well as the possibility to use the brush
templates as nanoreactors to generate metal nanoparticles. The
combination of stimuli-responsive polymer brushes and nanoparticles
exhibiting surface plasmon resonance, such as gold or silver, enables
the design of optical sensors based on reversible variations of the
brush conformation. Sensing devices are capable of detecting a variety
of extrinsic variations in their surrounding enviroments. The progress
in the development of such optical sensors using brush/particle
hybrids will be discussed in more detail.

Published: October 2014

ObjectiveStudies have indicated a blood pressure (BP)-lowering effect of milk-derived peptides in non-diabetic individuals, but the cardiometabolic effects of such peptides in patients with type 2 diabetes (T2D) are not known. We investigated the effect of milk fermented with Lactobacillus helveticus on BP, glycaemic control and cardiovascular risk factors in T2D.DesignA randomised, double-blinded, prospective, placebo-controlled study.MethodsIn one arm of a factorial study design, 41 patients with T2D were randomised to receive 300 ml milk fermented with L. helveticus (Cardi04 yogurt) (n=23) or 300 ml artificially acidified milk (placebo yogurt) (n=18) for 12 weeks. BPs were measured over 24-h, and blood samples were collected in the fasting state and during a meal test before and after the intervention.ResultsCardi04 yogurt did not reduce 24-h, daytime or nighttime systolic or diastolic BPs compared with placebo (P>0.05). Daytime and 24-h heart rate (HR) were significantly reduced in the group treated by Cardi04 yogurt compared with the placebo group (P<0.05 for both). There were no differences in HbA1c, plasma lipids, C-reactive protein, plasminogen activator inhibitor-1, tumour necrosis factor alpha, tissue-type plasminogen activator: Ag, and von Willebrand factor: Ag between the groups. The change in fasting blood glucose concentration differed significantly between the two groups with a larger increase in the placebo group (P<0.05).ConclusionsIngestion of milk fermented with L. helveticus compared with placebo for 12 weeks did not significantly reduce BP in patients with T2D. Our finding of lower HRs and fasting plasma glucose levels in T2D patients during ingestion of fermented milk needs further validation.
CRITICAL CARE ECHO ROUNDS: Echo in cardiac arrest
Authors: Zafiropoulos Andreas , Asrress Kaleab , Redwood Simon , Gillon Stuart , Walker David 
Published: October 2014

Management of medical cardiac arrest is challenging. The internationally agreed approach is highly protocolised with therapy and diagnosis occurring in parallel. Early identification of the precipitating cause increases the likelihood of favourable outcome. Echocardiography provides an invaluable diagnostic tool in this context. Acquisition of echo images can be challenging in cardiac arrest and should occur in a way that minimises disruption to cardiopulmonary resuscitation (CPR). In this article, the reversible causes of cardiac arrest are reviewed with associated echocardiography findings.CaseA 71-year-old patient underwent right upper lobectomy for lung adenocarcinoma. On the 2nd post-operative day, he developed respiratory failure with rising oxygen requirement and right middle and lower lobe collapse and consolidation on chest X-ray. He was commenced on high-flow oxygen therapy and antibiotics. His condition continued to deteriorate and on the 3rd post-operative day he was intubated and mechanically ventilated. Six hours after intubation, he became suddenly hypotensive with a blood pressure of 50 systolic and then lost cardiac output. ECG monitoring showed pulseless electrical activity. CPR was commenced and return of circulation occurred after injection of 1 mg of adrenaline. Focused echocardiography was performed, which demonstrated signs of massive pulmonary embolism. Thrombolytic therapy with tissue plasminogen activator was given and his condition stabilised.

Published: October 2014

AbstractQuantitative trait loci (QTL) mapping of wood properties in conifer species has focused on single time point measurements or on trait means based on heterogeneous wood samples (e.g., increment cores), thus ignoring systematic within-tree trends. In this study, functional QTL mapping was performed for a set of important wood properties in increment cores from a 17-yr-old Scots pine (Pinus sylvestris L.) full-sib family with the aim of detecting wood trait QTL for general intercepts (means) and for linear slopes by increasing cambial age. Two multi-locus functional QTL analysis approaches were proposed and their performances were compared on trait datasets comprising 2 to 9 time points, 91 to 455 individual tree measurements and genotype datasets of amplified length polymorphisms (AFLP), and single nucleotide polymorphism (SNP) markers. The first method was a multilevel LASSO analysis whereby trend parameter estimation and QTL mapping were conducted consecutively; the second method was our Bayesian linear mixed model whereby trends and underlying genetic effects were estimated simultaneously. We also compared several different hypothesis testing methods under either the LASSO or the Bayesian framework to perform QTL inference. In total, five and four significant QTL were observed for the intercepts and slopes, respectively, across wood traits such as earlywood percentage, wood density, radial fiberwidth, and spiral grain angle. Four of these QTL were represented by candidate gene SNPs, thus providing promising targets for future research in QTL mapping and molecular function. Bayesian and LASSO methods both detected similar sets of QTL given datasets that comprised large numbers of individuals.
MiFID: Eine systematische Analyse der Zielerreichung
Authors: Gomber Peter , Jäger Benedikt 
Published: October 2014

Zusammenfassung
Der vorliegende Artikel analysiert systematisch die Erreichung der MiFID-Ziele anhand der wissenschaftlichen Literatur. Ziel der MiFID ist es, die Rahmenbedingungen für einen effizienten und kostengünstigen Wertpapierhandel zu schaffen. Erreicht werden soll dies durch die Verschärfung des Wettbewerbs, die Integration der Märkte, die Offenlegung von Handelsintentionen und -geschäften sowie die Stärkung der rechtlichen Position der Investoren. Im Ergebnis zeigt sich, dass die Förderung des Wettbewerbs als erfolgreich bewertet wird, aber die regulatorischen Möglichkeiten der Marktintegration nicht ausgeschöpft werden. Ferner wird die Forderung nach einheitlichen Transparenzbestimmungen für alle Ordermechanismen nur teilweise umgesetzt. Der Anleger erfährt letztlich gegenüber Finanzintermediären durch die MiFID keinen höheren Schutz.

ABSTRACTHybrid halide perovskites represent one of the most promising solutions toward the fabrication of all solid nanostructured solar cells with improved efficiency and long-term stability. This article aims at investigating the structural properties of the iodide/chloride mixed-halide perovskites and correlating them with the photovoltaic performances of the related sensitized solar cells. We found out that, independently on the components ratio in the precursor solution, Cl incorporation, in a I-based structure, is possible only at relatively low concentration levels (below 3-4%). However, even if the material band-gap remains substantially unchanged, incorporation of Cl as a dopant dramatically improves the charge transport within the perovskite layer, explaining the outstanding performances of meso-superstructured solar cells based on this material.
Influence of Latanoprost on Retinal Microcirculation in Glaucoma
Authors: Kremmer S , Iliadou M , Anastassiou G , Schallenberg M , Vilser W , Steuhl K.P , Selbach J.M 
Published: October 2014

Purpose :
To test whether latanoprost has an influence on ocular haemodynamics, considering the general reputation of prostaglandins which is frequently associated with vasoconstriction. The effect of latanoprost on the retinal blood supply of treatment-naïve glaucoma patients was tested.

Materials and Methodology :
13 patients (7 male, 6 female) who had just recently been diagnosed with primary open-angle glaucoma (POAG) were treated with latanoprost (0.005%). The average age of our study group was 63.8 years (+/- 2.9 years).
The drug’s effect on retinal autoregulation was assessed by flicker test using the Dynamic Vessel Analyzer (DVA). Examinations took place before initializing treatment, after 4 weeks and once again after 4 to 6 months.

Results :
In our group of POAG patients, the IOP under treatment was significantly reduced about 25%. No intraindividual differences in systemic blood pressure and heart rate were observed. In DVA measurements of glaucoma patients, the maximum flicker dilation of the arteries was significantly lower than reported for healthy volunteers. Beyond that, POAG patients did not show significant differences in vessel diameters, peak amplitudes as well as maximum dilations of retinal arteries and veins before and under treatment with latanoprost (0.005%).

Conclusion :
Latanoprost markedly lowered the IOP but it did not exert a significant effect on retinal haemodynamics. There was neither a tendency towards vasoconstriction nor towards vasodilation. Sustaining reperfusion damage after topical latanoprost therapy thus seems to be highly unlikely. Further studies must show if sole IOP lowering or a dual positive effect – IOP lowering and improvement of retinal vessel autoregulation – have a more positive impact on the long term follow-up of glaucoma patients.
