Guidelines for surgical approaches for minimally invasive plate osteosynthesis in cats
Authors: Pozzi Antonio , Schmierer Philipp 
Published: June 2017

SummaryObjectives: Minimally invasive plate osteosynthesis (MIPO) is one of the most recent fixation techniques that embody the concept of biological osteosynthesis. Several studies evaluating MIPO in dogs have been published in the recent years. However, there are few clinical reports of MIPO in cats and no description of the surgical approaches. The purpose of our study was to describe the safe corridors for plate insertion in cats using the MIPO technique.Methods: The surgical approaches for the humerus, radius-ulna, femur and tibia were developed after reviewing the described techniques and surgical approaches for MIPO in dogs, while considering any relevant anatomical difference between dogs and cats. Following the MIPO approaches, the limbs were anatomically dissected and the relationship between proximal and distal positions of the implants and neurovascular structures was noted.Results: The surgical approaches developed for the humerus and radius-ulna differed from what had been reported previously, because relevant anatomical differences were found between dogs and cats. Anatomical landmarks for safe plate application were described for all the major long bones in cats. No damage to vital structures following plate insertion was detected in the dissection.Clinical significance: In this cadaveric study, we evaluated the safety of the surgical approaches for MIPO in cats. By respecting the anatomical landmarks described in this report, damage to the neurovascular structures can be avoided performing the MIPO technique in cats.

SummaryObjective: To compare the biomechanical properties of bone and implant constructs when used for the centre of rotation and angulation (CORA) based levelling osteotomy, with and without implantation of a trans-osteotomy headless compression screw tested under three-point flexural and torsional forces; thereby determining the contribution of a trans-osteotomy headless compression screw with regards to stability of the construct.Methods: Experimental biomechanical study utilizing 12 pairs of cadaveric canine tibias. Using the CORA based levelling osteotomy (CBLO) procedure, the osteotomy was stabilized with either a standard non-locking CBLO bone plate augmented with a headless compression screw (HCS) or a CBLO bone plate alone. Tibial constructs were mechanically tested in three-point craniocaudal flexural testing or in torsion.Results: In three-point flexural testing, the difference between the two constructs was not significant. In torsion, the difference in the angle of failure between constructs with a HCS (48.46°) and constructs without a HCS (81.65°) was significant (p = 0.036). Maximum torque achieved by constructs with a HCS (21.7 Nm) was greater than those without (18.7 Nm) (p = 0.056). Stiffness differences between both groups in torsion and bending were not significant. Use of a HCS did increase the stability of the CBLO construct in torsional testing, but not in flexural testing.
Anastomosis Between Ulnar And Radial Nerve: A Cadaveric Study
Authors: Ferreira Arquez Humberto 
Published: June 2017

Background: Brachial plexus variations are not rare. Variations in its terminal branches in the arm or forearm are frequently reported. Communications between branches of the brachial plexus are also not uncommon findings; however there is very little mention of communication between the radial and ulnar nerves in the literature. In view of this significance is performed this study with the purpose to determine any communications of radial nerve with neighboring peripheral nerves at level of axilla, arm, forearm.
Methods and Findings: A total of 17 cadavers with different age groups were used for this study. The upper limbs region (34 sides) were dissected carefully and photographed in the Morphology Laboratory at the University of Pamplona. Of the 34 upper limbs studied 33 showed normal morphology, the course and branching patterns of the nerves was normal (97.06%). In 1 specimen in the left forearm (2.94%), the radial and ulnar nerves were dissected and communicating branches were observed originating near the upper third in the posterior aspect of the forearm traveling from the ulnar to the radial nerve. The communicating branch was approximately 5.84 cm long and 1.73 mm in diameter. This anastomotic branch is an unusual anastomosis, no described in the literature between radial and ulnar nerve in forearm. Knowledge on the variant pattern of peripheral nerves is imperative not only for the surgeons, but also for the radiologists during image technology and MRI interpretations and for the anesthesiologists before administering anesthetic agents thus in diagnostic approaches.
Conclusions: Lack of understanding of these variations can also confound the assessment of the severity of nerve injury as well as recovery. Awareness of such anatomical variations is very important in order to proper diagnosis of sensorimotor symptoms.

Authors: Marques Ermelinda Maria Bernardo Gonçalves , Jabour Renata Saraiva 
Published: June 2017

Objective: To evaluate the functional capacity of the elderly and their association with quality of life.
Method: A transversal, descriptive and analytical study was carried out by an individual and anonymous interview to 247 elderly people. A structured questionnaire was used, composed of sociodemographic characterization, Katz Index, Lawton & Brody Scale and MOS SF-36 - Medical Outcome Study Short Form - 36.
Results: It was found that 80.6% of the elderly were independent in the ADL and 79.8% were independent in the IADL. On the whole, they show a reasonable quality of life. The study of the correlation between the results of the perception of the quality of life and the levels of independence in the ADL and the IADL revealed that the more independent elderly people tend to perceive a better quality of life.
Conclusion: These results can contribute to the nurses developing intervention measures that promote the maintenance or recovery of the functional capacity of the elderly and, consequently, improve their quality of life.

The Y-type Brown Dwarfs: Estimates of Mass and Age from New Astrometry, Homogenized Photometry, and Near-infrared Spectroscopy
Authors: Leggett S. K. , Tremblin P. , Esplin T. L. , Luhman K. L. , Morley Caroline V.

Abstract
The survey of the mid-infrared sky by the Wide-field Infrared Survey Explorer (WISE) led to the discovery of extremely cold, low-mass brown dwarfs, classified as Y dwarfs, which extend the T class to lower temperatures. Twenty-four Y dwarfs are known at the time of writing. Here we present improved parallaxes for four of these, determined using Spitzer images. We give new photometry for four late-type T and three Y dwarfs and new spectra of three Y dwarfs, obtained at Gemini Observatory. We also present previously unpublished photometry taken from HST, ESO, Spitzer, and WISE archives of 11 late-type T and 9 Y dwarfs. The near-infrared data are put onto the same photometric system, forming a homogeneous data set for the coolest brown dwarfs. We compare recent models to our photometric and spectroscopic data set. We confirm that nonequilibrium atmospheric chemistry is important for these objects. Nonequilibrium cloud-free models reproduce well the near-infrared spectra and mid-infrared photometry for the warmer Y dwarfs with 425 ≤ T
eff (K) ≤ 450. A small amount of cloud cover may improve the model fits in the near-infrared for the Y dwarfs with 325 ≤ T
eff (K) ≤ 375. Neither cloudy nor cloud-free models reproduce the near-infrared photometry for the T
eff = 250 K Y dwarf W0855. We use the mid-infrared region, where most of the flux originates, to constrain our models of W0855. We find that W0855 likely has a mass of 1.5–8 Jupiter masses and an age of 0.3–6 Gyr. The Y dwarfs with measured parallaxes are within 20 pc of the Sun and have tangential velocities typical of the thin disk. The metallicities and ages we derive for the sample are generally solar-like. We estimate that the known Y dwarfs are 3 to 20 Jupiter-mass objects with ages of 0.6–8.5 Gyr.

Abstract
Using high-quality observed period–luminosity (P–L) relations in both Magellanic Clouds in the VIJHK
s bands and optical and near-infrared Wesenheit indices, we determine the effect of metallicity on Cepheid P–L relations by comparing the relative distance between the LMC and SMC as determined from the Cepheids to the difference in distance between the Clouds that has been derived with very high accuracy from late-type eclipsing binary systems. Within an uncertainty of 3%, which is dominated by the uncertainty on the mean difference in metallicity between the Cepheid populations in the LMC and SMC, we find metallicity effects smaller than 2% in all bands and in the Wesenheit indices, consistent with a zero metallicity effect. This result is valid for the metallicity range from −0.35 dex to −0.75 dex corresponding to the mean [Fe/H] values for classical Cepheids in the LMC and SMC, respectively. Yet most Cepheids in galaxies beyond the Local Group and located in the less crowded outer regions of these galaxies do fall into this metallicity regime, making our result important for applications to determine the distances to spiral galaxies well beyond the Local Group. Our result supports previous findings that indicated a very small metallicity effect on the near-infrared absolute magnitudes of classical Cepheids, and resolves the dispute about the size and sign of the metallicity effect in the optical spectral range. It also resolves one of the most pressing problems in the quest toward a measurement of the Hubble constant with an accuracy of 1% from the Cepheid–supernova Ia method.
Constraining Anisotropic Lorentz Violation via the Spectral-lag Transition of GRB 160625B
Authors: Wei Jun-Jie , Wu Xue-Feng , Zhang Bin-Bin , Shao Lang , Mészáros Peter , Kostelecký V. Alan 
Published: June 2017

Abstract
Violations of Lorentz invariance can lead to an energy-dependent vacuum dispersion of light, which results in arrival-time differences of photons with different energies arising from a given transient source. In this work, direction-dependent dispersion constraints are obtained on nonbirefringent Lorentz-violating effects using the observed spectral lags of the gamma-ray burst GRB 160625B. This burst has unusually large high-energy photon statistics, so we can obtain constraints from the true spectral time lags of bunches of high-energy photons rather than from the rough time lag of a single highest-energy photon. Also, GRB 160625B is the only burst to date having a well-defined transition from positive lags to negative lags, providing a unique opportunity to distinguish Lorentz-violating effects from any source-intrinsic time lag in the emission of photons of different energy bands. Our results place comparatively robust two-sided constraints on a variety of isotropic and anisotropic coefficients for Lorentz violation, including the first bounds on Lorentz-violating effects from operators of mass dimension 10 in the photon sector.
The Origin of Compressible Magnetic Turbulence in the Very Local Interstellar Medium
Authors: Zank G. P. , Du S. , Hunana P. 
Published: June 2017

Abstract

Voyager 1 observed compressible magnetic turbulence in the very local interstellar medium (VLISM). We show that inner heliosheath (IHS) fast- and slow-mode waves incident on the heliopause (HP) generate VLISM fast-mode waves only that propagate into the VLISM. We suggest that this is the origin of compressible turbulence in the VLISM. We show that fast- and slow-mode waves transmitted across a tangential discontinuity such as the HP are strongly refracted on crossing the HP and subsequently propagate at highly oblique angles to the VLISM magnetic field. Thus, fast-mode waves in the VLISM contribute primarily to the compressible and not the transverse components of the VLISM fluctuating magnetic field variance

since

and

. If the fast- and slow-mode waves in the IHS exhibit a Kolmogorov-like

power spectral density, as appears to be observed by Voyager 1, then the corresponding transmitted spectral density in the VLISM forms an amplified

power law. Consequently, the HP “radiates” fast-mode fluctuations into the VLISM, and the heliosphere therefore mediates the character of turbulence in the VLISM. In particular, we predict the form of the VLISM magnetic turbulence power spectral density to be a superposition of the background pristine interstellar turbulence spectrum and the fast-mode spectrum generated by the interaction of fast- and slow-mode IHS waves with the HP, i.e., a power law with an enhanced feature or “bump” corresponding to the contribution by fast-mode turbulence radiated by the HP. We note the applicability of these results to the generation of compressible turbulence in the local interstellar medium surrounding the asterospheres of stars.
Thermonuclear Bursts with Short Recurrence Times from Neutron Stars Explained by Opacity-driven Convection
Authors: Keek L. , Heger A. 
Published: June 2017

Abstract
Thermonuclear flashes of hydrogen and helium accreted onto neutron stars produce the frequently observed Type I X-ray bursts. It is the current paradigm that almost all material burns in a burst, after which it takes hours to accumulate fresh fuel for the next burst. In rare cases, however, bursts are observed with recurrence times as short as minutes. We present the first one-dimensional multi-zone simulations that reproduce this phenomenon. Bursts that ignite in a relatively hot neutron star envelope leave a substantial fraction of the fuel unburned at shallow depths. In the wake of the burst, convective mixing events driven by opacity bring this fuel down to the ignition depth on the observed timescale of minutes. There, unburned hydrogen mixes with the metal-rich ashes, igniting to produce a subsequent burst. We find burst pairs and triplets, similar to the observed instances. Our simulations reproduce the observed fraction of bursts with short waiting times of ∼30%, and demonstrate that short recurrence time bursts are typically less bright and of shorter duration.

Background Sodium taurocholate co-transporting polypeptide (NTCP) is a cell receptor for HBV. The S267F variant on the NTCP gene is inversely associated with the chronicity of HBV infection, progression to cirrhosis and hepatocellular carcinoma in East Asian populations. The aim of this study was to determine whether the S267F variant was associated with response to pegylated interferon (PEG-IFN) in patients with chronic HBV infection. Methods A total of 257 patients with chronic HBV, treated with PEG-IFN for 48 weeks, were identified from 13 tertiary hospitals included in the hepatitis B database of the Thai Association for the Study of the Liver (THASL). Results Of these, 202 patients were infected with HBV genotype C (84.9%); 146 patients were hepatitis B e antigen (HBeAg)-positive (56.8%). Genotypic frequencies of the S267F polymorphism were 85.2%, 14.8% and 0% for the GG, GA and AA genotypes, respectively. S267F GA was associated with sustained alanine aminotransferase (ALT) normalization (OR = 3.25, 95% CI 1.23, 8.61; P=0.02) in HBeAg-positive patients. Patients with S267F variant tended to have more virological response, sustained response with hepatitis B surface antigen (HBsAg) loss at 24 weeks following PEG-IFN treatment. There was no association between the S267F variant and improved patient outcomes in HBeAg-negative patients. Conclusions The S267F variant on the NTCP gene is independently associated with sustained normalization of ALT following treatment with PEG-IFN in patients with HBV infection who are HBeAg-positive. The findings of this study provide additional support for the clinical significance of the S267F variant of NTCP beyond HBV entry.

Le bassin amazonien fournit des exemples emblématiques de « fluvitoires » issus de la maîtrise progressive des fleuves depuis les phases de leur exploration, de leur occupation et enfin de leur insertion régionale dans une Amazonie en grande transformation.
Scrobipalpa atriplicella(Lepidoptera: Gelechiidae), an invasive insect attacking quinoa (Amaranthaceae) in North America
Authors: Mori Boyd A. , Dutcheshen Colin , Wist Tyler J. 
Published: June 2017

AbstractQuinoa,Chenopodium quinoaWilldenow (Amaranthaceae), cultivation has expanded beyond its historical range in South America into Europe and North America due to its high nutritional properties for human consumption. With the introduction of a crop into a novel range comes the potential for insect pest issues. Here, using traditional morphology and DNA barcoding we identify larvae ofScrobipalpa atriplicella(von Röslerstamm) (Lepidoptera: Gelechiidae), an introduced Eurasian moth, feeding on quinoa throughout the Prairie region of western Canada. Larvae can feed within the stem, on foliage, and directly on seed within the panicles, which can result in up to a 100% yield loss. We summarise distinguishing adult characteristics, potential host plants, and give initial remarks on the life cycle of this moth and its known host range in Canada. The potential for high yield losses makes further investigation ofS. atriplicellaa priority to maintain and expand sustainable quinoa production in Canada.

Dispute resolution and conflict management in Germany
Despite the positive development of the European Mediation Directive and its translation in the German Mediation Law, in 2014 only 1.5% of the cases in court proceedings at the lower German courts were referred to court mandated conciliation or mediation proceedings. Against this background and in the context of a broader ten years research project, PricewaterhouseCoopers and the Institute of Conflict Management at the European University Viadrina Frankfurt (Oder) initiated a series of studies in 2005. This series was recently concluded with the fifth study conducted end of 2015 and published in October 2016. In addition to assessing the overall corporate landscape in Germany with regard to commercial dispute resolution, the study also considered the future developments and the required changes for further advancing this field.

Published: June 2017

La psychologie évolutionniste a fourni un apport considérable à plusieurs secteurs de recherche en psychologie, incluant la science du bonheur. Certains obstacles à l’atteinte du bonheur sont identifiés : une discordance entre environnements ancestraux et modernes ainsi que des mécanismes psychologiques façonnés par la sélection qui induisent des affects négatifs (par exemple, la jalousie). Par ailleurs, d’autres facteurs psychologiques semblent servir à l’élaboration d’une récompense psychologique, indiquant qu’un problème d’adaptation est ou sera résolu de façon satisfaisante. Finalement, des suggestions sont proposées pour promouvoir les affects positifs et pour favoriser la recherche dans une perspective évolutionniste.

La recherche dans le domaine de la motivation a démontré que la présence de buts personnels est associée au bien-être psychologique (BEP). Un programme de 14 semaines conçu pour aider les participants à réaliser leurs projets a été offert à des personnes âgées (≥ 65 ans) dépressives (BDI-II ≥ 9; M = 22,05) afin d’améliorer leur BEP. Les niveaux de BEP, de dépression et d’anxiété des personnes qui ont participé au programme (n = 24) ont été comparés à ceux d’un groupe contrôle (n = 18). Les analyses ont montré que les participants au programme se sont améliorés significativement sur la plupart des indicateurs de BEP, incluant la dépression, ce qui semble indiquer qu’un programme de gestion des buts pourrait être une manière innovatrice de promouvoir la santé mentale des aînés dépressifs. Toutefois, l’amélioration est observée uniquement pour la sérénité et le sens à la vie dans les analyses comparatives avec le groupe contrôle. Les études ultérieures devraient tenter de développer des programmes de promotion de la santé mentale qui offrent aux individus des moyens d’atteindre un état de fonctionnement optimal.
