Published: October 2015

ABSTRACTBackgroundThe use of oral anticoagulation or dual antiplatelet therapy (DAPT) is recommended within the first 45 days after left atrial appendage (LAA) closure using the Watchman device because of incomplete device endothelialization. This study reports for the first time the feasibility of novel oral anticoagulants (NOAC) in these patients.HypothesisNOAC therapy is safe and effective after LAA closure.MethodsInterventional LAA closure was performed successfully in 45 patients. Of these, 18 patients received NOAC during the first 45 days after implantation and 27 patients received DAPT. Transesophageal echocardiography was conducted 45 days after implantation. The primary study endpoint was abnormal thrombus apposition 45 days after implantation. Secondary study endpoints were death from any cause, major adverse cardiac and cerebrovascular events (MACCE), and major bleedings.ResultsAfter 45 days, transesophageal echocardiography revealed no abnormal thrombus apposition. During a follow‐up of 417 ± 323 days, 7 patients died. No stroke or transient ischemic attack occurred. Nonfatal myocardial infarction occurred in 1 patient. There was a nonsignificant trend for lower all‐cause mortality (P = 0.159) and occurrence of MACCE (P = 0.096) in the NOAC group compared with the DAPT group. Overall, 6 patients suffered from a major bleeding (NOAC, n = 3; DAPT, n = 3). In NOAC group, major bleedings (at day 205, 688, and 736) occurred long after termination of NOAC therapy. There was no significant difference in the frequency of major bleedings in different groups.ConclusionsOur pilot study suggests that NOAC therapy within the first 45 days after interventional LAA closure is safe and effective.
Extraordinary Synergy in Attenuating Microwave Radiation with Cobalt‐Decorated Graphene Oxide and Carbon Nanotubes in Polycarbonate/Poly(styrene‐co‐acrylonitrile) Blends
Authors: Pawar Shital Patangrao , Bose Suryasarathi 
Published: October 2015

AbstractPolymeric nanocomposites were developed using polycarbonate (PC) and poly(styrene‐co‐acrylonitrile) (SAN) containing cobalt nanoparticles decorated onto partially reduced graphene oxide (rGO) sheets and multiwalled carbon nanotubes (MWNTs). In order to absorb microwave radiations, the PC phase was rendered electrically conducting by selectively localizing the MWNTs in the PC phase of the blends. The synergetic effect from the conducting phase (MWNTs), the dielectric phase (rGO), and the ferromagnetic phase (cobalt nanoparticles) on microwave absorption was assessed by measuring the scattering parameters using a vector network analyzer coupled to a coaxial line. The electromagnetic interference (EMI) shielding effectiveness (SE) was studied over a broad range of frequencies including the X‐band (8–12 GHz) and the Ku‐band (12–18 GHz). This strategy resulted in enhanced electrical conductivity and facilitated in outstanding microwave absorption. For instance, the PC/SAN blends with MWNTs manifested significantly high total shielding effectiveness (SET) mainly through absorption, in contrast to PC/MWNT composites for which reflection dominated the attenuation mechanism. The interconnected network of MWNTs and cobalt‐decorated r‐GO (rGO‐Co) resulted in enhanced electrical conductivity and EMI shielding effectiveness (SE). This in turn resulted in a shielding effectiveness of −34 dB at 18 GHz. The mechanism of EM wave absorption was systematically evaluated through detailed analysis of relative permittivity and permeability in the measured frequency regime. The absorption of EM radiation was noticeably enhanced due to high dielectric and large magnetic losses in the blends containing rGO‐Co and MWNTs. Moreover, it was also realized that the significantly enhanced attenuation constant resulted in maximum microwave absorption in the blend containing MWNT and rGO‐Co.

AbstractEr3+–Yb3+ co‐doped Lu3Ga5O12 nanogarnets were prepared and characterized; their structural and luminescence properties were determined as a function of the Yb3+ concentration. The morphology of the nanogarnets was studied by HRTEM. Under 488 nm excitation, the nanogarnets emit green, red, and near‐infrared light. The decay curves for the (4S3/2, 2H11/2) and 4F9/2 levels of the Er3+ions exhibit a non‐exponential nature under resonant laser excitation and their effective lifetimes are found to decrease with an increase in the Yb3+ concentration from 1.0 to 10.0 mol %. The non‐exponential decay curves are well fitted to the Inokuti–Hirayama model for S=8, indicating that the mechanism of interaction for energy transfer between the optically active ions is of dipole–quadrupole type. Upon 976 nm laser excitation, an intense green upconverted emission is clearly observed by the naked eyes. A significant enhancement of the red‐to‐green intensity ratio of Er3+ ions was observed with an increase in Yb3+ concentration. The power dependence and the dynamics of the upconverted emission confirm the existence of two‐photon upconversion processes for the green and red emissions.

Published: October 2015

AbstractUltrafine and monodispersed Pd particles with a size of approximately 1.7 nm on pristine graphene are decorated with a low loading of Pt through a spontaneous deposition method. The electrocatalytic activity and poisoning species tolerance toward formic acid oxidation is improved after Pt decoration. Theoretical calculations reveal more continuous d‐states of the partial density of states and a downshift of the d‐band center in the Pt‐decorated Pd catalysts, which result in better electrocatalytic performance.

BackgroundThe triple test, i.e., cytology combined with clinical and radiological findings, is the goal for accurate assessment of palpable breast lesions. Because of the limitations of fine‐needle aspiration cytology (FNAC), its utility has somewhat decreased nationwide. We have been using a combination of physical examination, radiological modalities, and FNAC for the diagnosis of palpable/nonpalpable breast mass lesions for the last 23 years. Our institutional experience of the last 10 years is presented here, using FNAC of breast lesions along with an analysis of the diagnostic accuracy.Methods4956 breast aspirates in 4860 cases were collected from the computer database of Haydarpasa Numune Education and Research Hospital in Istanbul, Turkey. Most of the FNACs were performed under ultrasound guidance and FNAC procedures were performed by radiologists and pathologists who used 22 gauge needles. Cytological diagnoses were classified as “unsatisfactory”, “benign”, “malignant”, “atypical/probably benign”, “atypical/probably malignant”, and “atypical/NOS” (not otherwise specified) and were compared to the histopathological diagnoses obtained from core needle biopsy, lumpectomy or mastectomy to give an assessment of the diagnostic performance of FNAC in 733 aspirates.ResultsThe sensitivity, specificity, accuracy, positive and negative predictive value, false positive, and false negative rates of FNAC were 98.02, 90.58, 95.97, 96.48, 94.54, 2.6, and 1.4%, respectively.ConclusionsThis study once again shows that FNAC is a reliable method for the initial evaluation and diagnosis of breast masses. In case of any suspicious conditions, FNAC, and core biopsy are considered complementary to one another. Diagn. Cytopathol. 2015;43:978–986. © 2015 Wiley Periodicals, Inc.

AbstractDue to severe water resource shortage, genetics of and breeding for DT (drought tolerance) in rice (Oryza sativa L.) have become one of the hot research topics. Identification of grain yield QTLs (quantitative trait loci) directly related to the DT trait of rice can provide useful information for breeding new drought‐resistant and water‐saving rice varieties via marker‐assisted selection. A population of 105 advanced BILs (backcross introgression lines) derived from a cross between Zhenshan97B and IRAT109 in Zhenshan97B background were grown under drought stress in a field experiment and phenotypic traits were investigated. The results showed that in the target interval of RM273‐RM255 on chromosome 4, three main‐effect QTLs related to panicle length, panicle number, and spikelet number per panicle were identified (LOD [logarithm of the odds] > 2.0). The panicle length‐related QTL had two loci located in the neighboring intervals of RM17308‐RM17305 and RM17349‐RM17190, which explained 18.80% and 20.42%, respectively, of the phenotypic variation, while the panicle number‐related QTL was identified in the interval of RM1354‐RM17308, explaining 11.47% of the phenotypic variation. As far as the spikelet number per panicle‐related QTL was concerned, it was found to be located in the interval of RM17308‐RM17305, which explained 28.08% of the phenotypic variation. Using the online Plant‐GE query system, a total of 13 matched ESTs (expressed sequence tags) were found in the target region, and of the 13 ESTs, 12 had corresponding predicted genes. For instance, the two ESTs CB096766 and CA765747 were corresponded to the same predicted gene LOC_Os04g46370, while the other four ESTs, CA754286, CB000011, CX056247, and CX056240, were corresponded to the same predicted gene LOC_Os04g46390.
Exceptional avian herbivores: multiple transitions toward herbivory in the bird order Anseriformes and its correlation with body mass
Authors: Olsen Aaron M. 
Published: October 2015

AbstractHerbivory is rare among birds and is usually thought to have evolved predominately among large, flightless birds due to energetic constraints or an association with increased body mass. Nearly all members of the bird order Anseriformes, which includes ducks, geese, and swans, are flighted and many are predominately herbivorous. However, it is unknown whether herbivory represents a derived state for the order and how many times a predominately herbivorous diet may have evolved. Compiling data from over 200 published diet studies to create a continuous character for herbivory, models of trait evolution support at least five independent transitions toward a predominately herbivorous diet in Anseriformes. Although a nonphylogenetic correlation test recovers a significant positive correlation between herbivory and body mass, this correlation is not significant when accounting for phylogeny. These results indicate a lack of support for the hypothesis that a larger body mass confers an advantage in the digestion of low‐quality diets but does not exclude the possibility that shifts to a more abundant food source have driven shifts toward herbivory in other bird lineages. The exceptional number of transitions toward a more herbivorous diet in Anseriformes and lack of correlation with body mass prompts a reinterpretation of the relatively infrequent origination of herbivory among flighted birds.

AimTraditionally, risk stratification in heart failure (HF) emphasizes assessment of high risk. We aimed to determine if biomarkers could identify patients with HF at low risk for death or HF rehospitalization.Methods and resultsThis analysis was a substudy of The Coordinating Study Evaluating Outcomes of Advising and Counselling in Heart Failure (COACH) trial. Enrolment of HF patients occurred before discharge. We defined low risk as the absence of death and/or HF rehospitalizations at 180 days. We tested a diverse group of 29 biomarkers on top of a clinical risk model, with and without N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP), and defined the low risk biomarker cut‐off at the 10th percentile associated with high positive predictive value. The best performing biomarkers together with NT‐proBNP and cardiac troponin I (cTnI) were re‐evaluated in a validation cohort of 285 HF patients. Of 592 eligible COACH patients, the mean (± SD) age was 71 (± 11) years and median (IQR) NT‐proBNP was 2521 (1301–5634) pg/mL. Logistic regression analysis showed that only galectin‐3, fully adjusted, was significantly associated with the absence of events at 180 days (OR 8.1, 95% confidence interval 1.06–50.0, P = 0.039). Galectin‐3, showed incremental value when added to the clinical risk model without NT‐proBNP (increase in area under the curve from 0.712 to 0.745, P = 0.04). However, no biomarker showed significant improvement by net reclassification improvement on top of the clinical risk model, with or without NT‐proBNP. We confirmed our results regarding galectin‐3, NT‐proBNP, and cTnI in the independent validation cohort.ConclusionWe describe the value of various biomarkers to define low risk, and demonstrate that galectin‐3 identifies HF patients at (very) low risk for 30‐day and 180‐day mortality and HF rehospitalizations after an episode of acute HF. Such patients might be safely discharged.
The role of ordinary conversation and shared activity in the main effect between perceived support and affect
Authors: Woods William C. , Lakey Brian , Sain Travis 
Published: October 2015

AbstractPeople with high perceived support have better mental health, but how this occurs is not well understood. We tested hypotheses from relational regulation theory that the main effect between perceived support and affect primarily reflects ordinary conversation and shared activity. In two studies (n = 193; n = 149), students rated three important network members and psychological reactions to each. In a third study (n = 72) strangers shared an activity in a round‐robin design. Affect was strongly determined by with who participants were interacting or thinking about. Perceived support, ordinary conversation, and shared activity were strongly linked, and each was related to high positive affect, low negative affect, perceived similarity, and few negative thoughts. Perceived support's link to affect emerged when strangers shared a brief activity. Thus, much of perceived support's main effect with affect could be explained as resulting from ordinary conversation and shared activity.
Chronic effects of hydroxypropyl-β-cyclodextrin on reproduction in the American flagfish (Jordanella floridae) over one complete life cycle

Abstract

Understanding the environmental risks of pharmaceuticals and personal care products (PPCPs) has become very important in the field of aquatic toxicology. Hydroxylpropyl-β-cyclodextrin (HPβCD) is an amphiphilic, toroidal shaped molecule with the ability to form noncovalent inclusion complexes with a variety of guest molecules. The molecule can reduce volatility as well as improve the aqueous solubility of apolar guest compounds and is an emerging PPCP. As such, HPβCD is the active ingredient in Febreze (Procter & Gamble) and is extensively used as an excipient in the pharmaceutical industry. With the potential for entering the environment through waste-water treatment plant (WWTP) effluent, HPβCD poses an unknown risk to nontarget aquatic biota. A 145-d chronic full life-cycle exposure using American flagfish (Jordanella floridae) was completed using flow-through nominal concentrations of 0 µg/L (control), 5 µg/L, 16 µg/L, 50 µg/L, 160 µg/L, 500 µg/L, and 1600 μg/L of HPβCD maintained via a peristaltic pump. Fecundity, growth, and liver somatic index were all monitored, and no significant difference was found between treatments and controls (p &gt; 0.05). However, a significant increase in the gonadosomatic index was observed in females exposed to HPβCD (p ≤ 0.05). Reduced offspring growth was observed after exposure in the same manner as the parental generation (p ≤ 0.05). Furthermore, an acute copper toxicity challenge assay was conducted on second-generation flagfish larvae, and a decrease in copper tolerance was observed in larval progeny from parents exposed to HPβCD.
