AbstractForests situated above active fault zones may record hillslope evolution, thus holding information about recent seismic events. Lenga trees (Nothofagus pumilio) extend across the Magallanes–Fagnano fault system (MFFS), the active transform boundary between the South American and Scotia plates. Coseismic surface ruptures along the fault scarp tilt trees located uphill. During the interseismic period, tree growth curves the trunks. Annual tree rings from the study area show abrupt changes from concentric to asymmetric, allowing the timing of major historical earthquakes to be established. In this case, tree‐ring analysis suggests rupture on theMFFSfault scarp in 1883 ± 5 and 1941 ± 10, coinciding with the February 1, 1879 (Modified Mercalli Scale,VI) and the December 17, 1949 (Ms 7.8) earthquakes in Tierra del Fuego. Our results provide evidence that this fault system was the source of these earthquakes, which has implications for seismic hazard in the study region.

BackgroundPosttransfusion purpura (PTP) is a serious transfusion complication resulting in sudden thrombocytopenia with bleeding. The study's objective was to assess PTP occurrence and potential risk factors among the inpatient US elderly, ages 65 and older, during 2011 through 2012.Study Design and MethodsThis retrospective claims‐based study utilized large Medicare databases for calendar years 2011 and 2012. Transfusions of blood and blood components were identified by recorded ICD‐9‐CM procedure codes and revenue center codes, and PTP was ascertained via ICD‐9‐CM diagnosis code. Our study evaluated PTP rates (per 100,000 inpatient transfusion stays) among elderly Medicare beneficiaries, overall and by age, sex, race, number of units, and blood components transfused. Multivariate regression analyses were used to assess potential risk factors.ResultsAmong 4,336,338 inpatient transfusion stays for elderly beneficiaries during the study period, 78 had a PTP diagnosis code recorded, an overall rate of 1.8 per 100,000 stays. PTP occurrence varied by the blood components, units transfused, and other characteristics. Significantly higher odds of PTP were found for platelet (PLT)‐containing transfusions, with greater number of units transfused, as well as for elderly with histories of cardiac arrhythmias (odds ratio [OR], 2.65; 95% confidence interval [CI], 1.43‐4.93), coagulopathy (OR, 1.79; 95% CI, 1.01‐3.21), leukemia (OR, 2.37; 95% CI, 1.07‐5.26), transplant (OR, 2.68; 95% CI, 1.41‐5.09), and other conditions.ConclusionOur population‐based study suggests a substantially higher PTP risk with PLT‐containing transfusions. The study also suggests increased PTP risk with greater number of units transfused as well as the importance of underlying health conditions and prior recipient alloimmunization for PTP occurrence among the elderly.

BackgroundDonkeys are becoming increasingly important worldwide; therefore a reliable and accurate method of diagnosing disease is necessary. Flow cytometry‐based hematologic analyzers are present in veterinary laboratories, but performance of LaserCyte has not been evaluated in donkeys.ObjectivesThe objective of the study was to compare the results of donkey blood obtained from the LaserCyte with impedance and manual methods.MethodsBlood samples were collected from 84 healthy donkeys (1–20 years old) and measured with LaserCyte, Sysmex F‐820 and manually. Agreement between methods was studied using Passing–Bablok test and Bland–Altman plots. Influence of blood abnormalities found on blood smears on LaserCyte counts was examined using Mann–Whitney or Kruskal–Wallis test. Intraassay precision was calculated.ResultsHematologic variables obtained from the LaserCyte were significantly different from those obtained with impedance or manual methods; numerous values were flagged. Agreement between LaserCyte and manual method was poor for the majority of variables, but agreement between LaserCyte and impedance was only poor forHCT,MCH, andMCHC. LaserCyte had an intraassay precision < 10% for RBC and platelet variables, and > 10% forWBCvariables.ConclusionsLaserCyte results were not interchangeable with results from other methods due to poor agreement. LaserCyte provided no additional hematologic variables or clinically relevant indices for donkey blood analysis. A large number of results were flagged, requiring the evaluation of blood smears. No benefits were found for the use of LaserCyte analyzer over the use of impedance or manual methods in this study. Specific software for LaserCyte for donkey blood would be beneficial.

Published: July 2014

BackgroundHair cycle arrest (alopecia X) refers to a canine alopecic condition of unknown pathogenesis, characterized by symmetrical, nonpruritic and noninflammatory alopecia that spares the head and distal extremities.Hypothesis/ObjectivesThe objective of this study was prospectively to evaluate the efficacy of a 4.7 mg deslorelin implant in the treatment of intact male and neutered female dogs affected by hair cycle arrest.AnimalsTen Pomeranian dogs (eight intact males, two neutered females), four Italian spitz (three intact males, one neutered female), three miniature poodles (two intact males, one neutered female), two Siberian huskies (both intact males) and one intact male chow chow dog with confirmed hair cycle arrest were included in the study.MethodsEach dog was treated with a subcutaneous sterile implant containing 4.7 mg deslorelin. Responder dogs were re‐implanted 6 months after the first implant in order to obtain a 1 year pharmacological exposure and 1 year of follow‐up.ResultsHair regrowth was visible within 3 months in 12 of 16 intact male dogs (75%); no hair regrowth was noted in any neutered female dogs. The overall response to therapy was 60%. No adverse effects were noted.Conclusions and clinical importanceThese findings suggest that deslorelin may be a treatment option for intact male dogs with idiopathic hair cycle arrest. Deslorelin is an alternative to current therapies and castration.
Inhibition of poly‐ADP ribose polymerase enzyme activity prevents hyperglycemia‐induced impairment of angiogenesis during wound healing

Published: July 2014

AbstractWe previously reported a zebrafish model of type I diabetes mellitus (DM) that can be used to study the hyperglycemic (HG) and metabolic memory (MM) states within the same fish. Clinically, MM is defined as the persistence of diabetic complications even after glycemic control is pharmacologically achieved. In our zebrafish model, MM occurs following β‐cell regeneration, which returns fish to euglycemia. During HG, fish acquire tissue deficits reflective of the complications seen in patients with DM and these deficits persist after fish return to euglycemia (MM). The unifying mechanism for the induction of diabetic complications involves a cascade of events that is initiated by the HG stimulation of poly‐ADP ribose polymerase enzyme (Parp) activity. Additionally, recent evidence shows that the HG induction of Parp activity stimulates changes in epigenetic mechanisms that correlate with the MM state and the persistence of complications. Here we report that wound‐induced angiogenesis is impaired in DM and remains impaired when fish return to a euglycemic state. Additionally, inhibition of Parp activity prevented the HG‐induced wound angiogenesis deficiency observed. This approach can identify molecular targets that will provide potential new avenues for therapeutic discovery as angiogenesis imbalances are associated with all HG‐damaged tissues.
Thermal Modeling and Experimental Validation for High Thermal
Conductivity Heat Pipe Thermal Ground Planes

Published: July 2014

Abstract
Thermal ground planes (TGPs) are flat, thin (external thickness of 2 mm) heat pipes which utilize two-phase cooling. The goal is to utilize TGPs as thermal spreaders in a variety of microelectronic cooling applications. In addition to TGPs and flat heat pipes, some investigators refer to similar devices as vapor chambers. TGPs are novel high-performance, integrated systems able to operate at a high power density with a reduced weight and temperature gradient. In addition to being able to dissipate large amounts of heat, they have very high effective axial thermal conductivities and (because of nanoporous wicks) can operate in high adverse gravitational fields. A three-dimensional (3D) finite element model is used to predict the thermal performance of the TGP. The 3D thermal model predicts the temperature field in the TGP, the effective axial thermal conductivity, and the evaporation and the condensation rates. A key feature of this model is that it relies on empirical interfacial heat transfer coefficient data to very accurately model the interfacial energy balance at the vapor–liquid saturated wick interface. Wick samples for a TGP are tested in an experimental setup to measure the interfacial heat transfer coefficient. Then the experimental heat transfer coefficient data are used for the interfacial energy balance. Another key feature of this model is that it demonstrates that for the Jakob numbers of interest, the thermal and flow fields can be decoupled except at the vapor–liquid saturated wick interface. This model can be used to predict the performance of a TGP for different geometries and implementation structures. This paper will describe the model and how it incorporates empirical interfacial heat transfer coefficient data. It will then show theoretical predictions for the thermal performance of TGP's, and compare with experimental results.

A new species of the tree genus Syzygium (Myrtaceae), S. sahyadricum is described and illustrated from the Montane Shola forests of Anamalai and Palni Phytogeographical region of Western Ghats. Although phenotypically closely similar to S. spathulatum and S. malabaricum, the new species is easily recognizable by the pale yellow coloured tender leaves with horizontal secondary nerves and white flowers in reduced metabotryoid, pedunculate inflorescence, which are flattened towards the apex. Scanning the Syzygium collections in various herbaria revealed that similar specimens from various localities of this phyto-region are available and most of them with erroneous ascriptions. The report of S. spathulatum Thwaites, a Sri Lankan endemic species in India, was due to misinterpretation of Beddome’s collection. In this paper taxonomic peculiarities of the new species and allied taxa are discussed for better understanding.

Pentad Evolution of Wintertime Impacts of the Madden–Julian Oscillation over the Contiguous United States
Authors: Baxter Stephen , Weaver Scott , Gottschalck Jon , Xue Yan 
Published: July 2014

Abstract
Lagged pentad composites of surface air temperature and precipitation are analyzed for the winter season (December–February) to assess the influence of the Madden–Julian oscillation (MJO) on the climate of the contiguous United States. Composites are based on the Wheeler and Hendon MJO index as well as an index developed and maintained at NOAA’s Climate Prediction Center (CPC), which is based on extended empirical orthogonal function analysis of upper-level velocity potential. Significant positive temperature anomalies develop in the eastern United States 5–20 days following Wheeler and Hendon MJO index phase 3, which corresponds to enhanced convection centered over the eastern Indian Ocean. At the same lag, positive precipitation anomalies are observed from the southern Plains to the Great Lakes region. Negative temperature anomalies appear in the central and eastern United States 10–20 days following Wheeler and Hendon MJO phase 7. These impacts are supported by an analysis of the evolution of 200-hPa geopotential height and zonal wind anomalies. Composites based on the CPC velocity potential MJO index generally yield similar results; however, they capture more cases since the index contains both interannual and subseasonal variability. There are some cases where the CPC index differs from that of WH in both MJO phase identification and its North American impacts, especially near the West Coast. This analysis suggests that MJO-related velocity potential anomalies can be used without the Wheeler and Hendon MJO index to predict MJO impacts.

Published: July 2014

BackgroundThe epidemiological decrease of Helicobacter pylori (Hp) infection has been recently associated to the increase of several extra‐intestinal allergic disorders.ObjectiveWe investigated the role of specific Hp IgG production in the development of IgE or not IgE mediated food allergy (FA) in children affected by atopic dermatitis (AD).MethodsFrom January 2010 to July 2013, 290 South Italian children, aged between 26 and 142 months, were consecutively referred to the Pediatric Clinic of the Pediatric Department at Second University of Naples and were diagnosed as affected by AD. The patients were classified in two groups on the basis of diagnosis of food allergy (88 FA affected and 202 not FA affected) and further divided on the basis of the diagnosis of atopy (63 IgE mediated and 23 not IgE mediated). Hp serum IgG was detected using an enzyme linked immunosorbent assay (ELISA) kit (Wampole® Helicobactor pylori IgG ELISA II, Wampole Laboratories, Cranbury, NJ) and Hp stool antigens using enzyme immunoassay (Premier Platinum HpSa plus, Cincinnati OH).ResultsWe found a statistically significant higher prevalence of Hp serology positivity in not FA vs. FA AD‐affected children (p  = 0.032) and a significant inverse association between FA and Hp immunization (1/OR 0.32 95% CI 0.11–0.95). Further, we identified an absolute prevalence Hp serology positivity in not‐IgE‐mediated rather than in IgE‐mediated FA AD‐affected patients (p  = 0.0006).ConclusionWe hypothesize that specific Hp IgG production could protect against the development of both FA and atopy in AD‐affected children.

Published: July 2014

Abstract
Graphene is highly sensitive to environmental influences, and thus, it is worthwhile to deposit protective layers on graphene without impairing its excellent properties. Hexagonal boron nitride (h-BN), a well-known dielectric material, may afford the necessary protection. In this research, we demonstrated the van der Waals epitaxy of h-BN nanosheets on mechanically exfoliated graphene by chemical vapor deposition, using borazine as the precursor to h-BN. The h-BN nanosheets had a triangular morphology on a narrow graphene belt but a polygonal morphology on a larger graphene film. The h-BN nanosheets on graphene were highly crystalline, except for various in-plane lattice orientations. Interestingly, the h-BN nanosheets preferred to grow on graphene than on SiO2/Si under the chosen experimental conditions, and this selective growth spoke of potential promise for application to the preparation of graphene/h-BN superlattice structures fabricated on SiO2/Si.

Published: July 2014

Abstract
The hollow graphene oxide spheres have been successfully fabricated from graphene oxide nanosheets utilizing a water-in-oil emulsion technique, which were prepared from natural flake graphite by oxidation and ultrasonic treatment. The hollow graphene oxide spheres were reduced to hollow graphene spheres at 500°C for 3 h under an atmosphere of Ar(95%)/H2(5%). The first reversible specific capacity of the hollow graphene spheres was as high as 903 mAh g-1 at a current density of 50 mAh g-1. Even at a high current density of 500 mAh g-1, the reversible specific capacity remained at 502 mAh g-1. After 60 cycles, the reversible capacity was still kept at 652 mAh g-1 at the current density of 50 mAh g-1. These results indicate that the prepared hollow graphene spheres possess excellent electrochemical performances for lithium storage. The high rate performance of hollow graphene spheres thanks to the hollow structure, thin and porous shells consisting of graphene sheets.

Pigeonpea genotypes influence parasitization preference and survival and development of the Helicoverpa armigera larval parasitoid, Campoletis chlorideae
Authors: Hugar Shiddalingappa V , Sharma Hari C , Basavan Goud Kondikallu 
Published: July 2014

AbstractStudies were undertaken to identify pigeonpea,Cajanus cajan(L.) Millspaugh and the wild relative of pigeonpea,Cajanus scarabaeoides(L.) (accession ICPW 125,) genotypes that are hospitable to the pod borer,Helicoverpa armigera(Hübner) (Lepidoptera: Noctuidae) larval parasitoid,Campoletis chlorideaeUchida (Hymenoptera: Ichneumonidae) for the management of this pest in pigeonpea based cropping systems. Percentage parasitization of theH. armigeralarvae by theC. chlorideaefemales was greater under no-choice conditions than under multi-choice conditions because of forced parasitization under no-choice conditions. Lowest parasitization was recorded on the wild relative, ICPW 125, which may be due to long nonglandular hairs and low survival ofH. armigeralarvae. Parasitization ofH. armigeralarvae was greater under no-choice, dual-choice and/or multi-choice conditions on ICPL 87, ICPL 87119 and ICPL 87091, which are susceptible toH. armigera, than on the pod borer-resistant genotypes ICPL 332WR, ICPL 84060 and ICPB 2042; while survival and development of the parasitoid was better onH. armigeralarvae fed on ICPL 87, ICPL 87119, LRG 41, ICP 7035 and ICPL 87091 than on ICPL 332WR, ICPL 84060, ICPB 2042 and ICPW 125. The genotypes ICPL 87, ICPL 87119, LRG 42 and ICPL 87091 that are hospitable toC. chloridae, are better suited for use in integrated pest management to minimize the losses due toH. armigerain pigeonpea.

Published: July 2014

Abstract
Readily available inexpensive substrate with high product yield is the key to restoring acetone-butanol-ethanol (ABE) fermentation to economic competitiveness. Lactose-replete cheese whey tends to favor the production of butanol over acetone. In the current study, we investigated the fermentability of milk dust powder with high lactose content, for ABE production by Clostridium acetobutylicum and Clostridium beijerinckii. Both microorganisms produced 7.3 and 5.8 g/L of butanol respectively, with total ABE concentrations of 10.3 and 8.2 g/L, respectively. Compared to fermentation with glucose, fermentation of milk dust powder increased butanol to acetone ratio by 16% and 36% for C. acetobutylicum and C. beijerinckii, respectively. While these results demonstrate the fermentability of milk dust powder, the physico-chemical properties of milk dust powder appeared to limit sugar utilization, growth and ABE production. Further work aimed at improving the texture of milk dust powder-based medium would likely improve lactose utilization and ABE production.
Expanded identification and characterization of mammalian circular RNAs
Authors: Guo Junjie U , Agarwal Vikram , Guo Huili , Bartel David P 
Published: July 2014

Abstract
Background
The recent reports of two circular RNAs (circRNAs) with strong potential to act as microRNA (miRNA) sponges suggest that circRNAs might play important roles in regulating gene expression. However, the global properties of circRNAs are not well understood.

Results
We developed a computational pipeline to identify circRNAs and quantify their relative abundance from RNA-seq data. Applying this pipeline to a large set of non-poly(A)-selected RNA-seq data from the ENCODE project, we annotated 7,112 human circRNAs that were estimated to comprise at least 10% of the transcripts accumulating from their loci. Most circRNAs are expressed in only a few cell types and at low abundance, but they are no more cell-type-specific than are mRNAs with similar overall expression levels. Although most circRNAs overlap protein-coding sequences, ribosome profiling provides no evidence for their translation. We also annotated 635 mouse circRNAs, and although 20% of them are orthologous to human circRNAs, the sequence conservation of these circRNA orthologs is no higher than that of their neighboring linear exons. The previously proposed miR-7 sponge, CDR1as, is one of only two circRNAs with more miRNA sites than expected by chance, with the next best miRNA-sponge candidate deriving from a gene encoding a primate-specific zinc-finger protein, ZNF91.

Conclusions
Our results provide a new framework for future investigation of this intriguing topological isoform while raising doubts regarding a biological function of most circRNAs.
