(+)‐N‐formylnorglaucine (1), an aporphine alkaloid containing a formyl group linked to the heterocyclic nitrogen, was isolated from the leaves of Unonopsis stipitata, an Amazon medicinal plant. The chemical structure was characterized based on 1D‐ and 2D‐NMR spectroscopy and HR‐ESI‐MS. NMR spectra revealed that 1 is composed of two rotamers (1a and 1b) in a ratio of approximately 2:1. In addition, the fragmentation behavior of 1 displayed an unusual fragmentation pattern compared to regular aporphine alkaloids. Thus, this compound is reported for the first time as a natural product in this study.
Conventional Monetary Policy Transmission During Financial Crises: An Empirical Analysis
Authors: Dahlhaus Tatjana 
Published: May 2016

SummaryThis paper studies the effects of a conventional monetary policy shock in the USA during times of high financial stress. The analysis is carried out by introducing a smooth transition factor model where the transition between states (‘normal’ and high financial stress) depends on a financial conditions index. Employing a quarterly dataset over the period 1970:Q1 to 2008:Q4 containing 108 US macroeconomic and financial time series, I find that a monetary policy shock during periods of high financial stress has stronger and more persistent effects on macroeconomic variables such as output, consumption and investment than it has during ‘normal’ times. Differences in effects among the regimes seem to originate from nonlinearities in both components of the credit channel, i.e. the balance sheet channel and the bank‐lending channel.

Parametric analysis of glenoid implant design and fixation type
Authors: Geraldes Diogo M. , Hansen Ulrich , Amis Andrew A. 
Published: May 2016

ABSTRACTCommon post‐operative problems in shoulder arthroplasty such as glenoid loosening and joint instability may be reduced by improvements in glenoid design, shape, material choice, and fixation method. A framework for parametric analysis of different implant fixation configurations was developed in order to efficiently sift through potential glenoid component designs. We investigated the influence of design factors such as fixation type, component thickness, and peg position, number, diameter, and length in a multi‐factorial design investigation. The proposed method allowed for simultaneous comparison of the mechanical performance of 344 different parametric variations of 10 different reference geometries with either large central fixation features or small peripheral pegs, undergoing four different worst‐case scenario loading conditions, and averaging 64.7 s per model. The impact of design parameters were assessed for different factors responsible for post‐operative problems in shoulder arthroplasty, such as bone volume preservation, stresses in the implant, central displacement or fixation stability, and the worst performing geometries all relied on conventional central fixation. Of the remaining geometries, four peripheral fixation configurations produced von Mises stresses comfortably below the material's yield strength. We show that the developed method allows for simple, direct, rapid, and repeatable comparison of different design features, material choices, or fixation methods by analyzing how they influence the bone‐implant mechanical environment. The proposed method can provide valuable insight in implant design optimization by screening through multiple potential design modifications at an early design evaluation stage and highlighting the best performing combinations according to the failure mechanism to mitigate. © 2016 Orthopaedic Research Society.

Published: May 2016

AbstractBACKGROUNDAgaricus bisporus (white button mushroom) is an important culinary and medicinal species of worldwide importance. The present study investigated for the first time whether it may be grown on substrates supplemented with Se alone or in combination with Cu and/or Zn (0.1–0.8 mmol L−1) to produce fruiting bodies of increased nutritional value.RESULTSAs found, substrate supplementation did not affect yielded biomass up to 0.6 mmol L−1 element concentrations regardless of the cultivation model. At 0.8 mmol L−1 Se + Cu and Se + Zn supplementation biomass comparable with controls still developed. The accumulation of trace elements in the fruiting bodies generally increased over the concentration gradient reaching its maximum at 0.6 mmol L−1 (for Se + Zn and Se + Cu + Zn) and 0.8 mmol L−1 (for Se and Se + Cu). The organic Se constituted the greatest share in total Se quota. As calculated, each 10 g of dried fruiting bodies of A. bisporus obtained from 0.6 or 0.8 mmol L−1 supplementation would represent 342–469% of the Recommended Daily Allowance (RDA) for Se, 43.4–48.5% for Cu and 5.2–5.8% for Zn.CONCLUSIONConsidering inexpensive methods of A. bisporus cultivation, global popularity and use of this mushroom, its biofortification with Se, Cu and Zn could have a practical application in deficiency prevention and assisted treatment. © 2016 Society of Chemical Industry
Evidence of Shared Genome‐Wide Additive Genetic Effects on Interpersonal Trauma Exposure and Generalized Vulnerability to Drug Dependence in a Population of Substance Users

Published: May 2016

AbstractExposure to traumatic experiences is associated with an increased risk for drug dependence and poorer response to substance abuse treatment (Claus & Kindleberger, 2002; Jaycox, Ebener, Damesek, & Becker, 2004). Despite this evidence, the reasons for the observed associations of trauma and the general tendency to be dependent upon drugs of abuse remain unclear. Data (N = 2,596) from the Study of Addiction: Genetics and Environment were used to analyze (a) the degree to which commonly occurring single nucleotide polymorphisms (SNPs; minor allele frequency > 1%) in the human genome explains exposure to interpersonal traumatic experiences, and (b) the extent to which additive genetic effects on trauma are shared with additive genetic effects on drug dependence. Our results suggested moderate additive genetic influences on interpersonal trauma, h2SNP‐Interpersonal = .47, 95% confidence interval (CI) [.10, .85], that are partially shared with additive genetic effects on generalized vulnerability to drug dependence, h2SNP‐DD = .36, 95% CI [.11, .61]; rG‐SNP = .49, 95% CI [.02, .96]. Although the design/technique does not exclude the possibility that substance abuse causally increases risk for traumatic experiences (or vice versa), these findings raise the possibility that commonly occurring SNPs influence both the general tendency towards drug dependence and interpersonal trauma.
Figure of merit for Kerr nonlinear plasmonic waveguides
Authors: Li Guangyuan , de Sterke C. Martijn , Palomba Stefano 
Published: May 2016

AbstractPlasmonic waveguides are promising in many applications because of their subwavelength field confinement, which can strongly enhance light‐matter interactions. Nevertheless, how to efficiently evaluate their Kerr nonlinear performance is still an open question because of the presence of relatively large linear losses. Here a simple and versatile figure of merit (FOM) is proposed for Kerr nonlinear waveguides with linear losses. To derive the FOM, a generalized full‐vectorial nonlinear Schrödinger equation governing nonlinear pulse propagation in a lossy waveguide is developed, and an approximate analytic solution of the degenerate four wave mixing conversion efficiency is derived and validated. The effectiveness of the FOM is verified with an all‐plasmonic and a hybrid‐plasmonic waveguide configuration. Rigorous results show that the optimal waveguide length for the highest conversion efficiency is ln 3 times the attenuation length. At this length, the upper limits of the conversion efficiency and the nonlinear phase shift are determined by the FOM. These results provide fundamental theory and useful guidance in exploring plasmonic waveguides for nonlinear optical applications.

Two for One: Using QAR to Increase Reading Comprehension and Improve Test Scores
Authors: Green Susan 
Published: May 2016

AbstractThis teaching tip describes an intervention used in a third‐grade classroom implemented to help students pass an end‐of‐grade reading comprehension test. Low scores on a practice end‐of‐grade comprehension test prompted a re‐examination of classroom reading instruction and a plan for intervention. This teaching tip describes the phases implemented over an eight‐week period to add the Question Answer Relationship (QAR) strategy to students’ reader's toolboxes to increase comprehension and improve test scores. Most student scores on end‐of‐grade test increased after this intervention, which supports the use of QAR to improve test scores while furthering literacy development.

ABSTRACTObjectivesTo determine the longitudinal behavior of fetal biometric measures and cerebroplacental hemodynamics throughout gestation in fetuses with congenital heart disease (CHD).MethodsFetal biometry and Doppler hemodynamics (uterine artery (UtA), umbilical artery (UA) and fetal middle cerebral artery (MCA)) were measured serially in a cohort of consecutive fetuses diagnosed with CHD. Evaluations were made at various time points, from diagnosis (20–25 weeks) to delivery, with at least two measurements per fetus that were at least 2 weeks apart. Fetuses were classified into three groups according to the pattern of blood supply to the brain (placental vs systemic) that would be expected on the basis of the type of CHD. All parameters were transformed into Z‐scores. A linear mixed model to analyze repeated measurements was constructed for each parameter to assess its behavior throughout gestation.ResultsFour hundred and forty‐four ultrasound examinations were performed in 119 CHD fetuses, with a median of two measurements per fetus. The fetuses presented a small head at diagnosis (biparietal diameter (BPD) Z‐score, −1.32 ± 0.99; head circumference (HC) Z‐score, −0.79 ± 1.02), which remained small throughout gestation. UtA and UA pulsatility indices (PI) showed a significant increase towards the end of pregnancy, whereas no significant changes were observed in MCA‐PI or cerebroplacental ratio (CPR) with gestational age. Both MCA and CPR presented significant differences in longitudinal behavior between CHD groups, while BPD and HC did not.ConclusionsCHD fetuses have a relatively small head from the second trimester of pregnancy, regardless of the type of CHD anomaly, and increasing resistance in the UtA and UA as pregnancy progresses, suggestive of increasing degree of placental impairment. Our findings indicate the early onset of mechanisms that could lead to poorer neurodevelopment later in life. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.
Fatty Acid Profiles of Some Fabaceae Seed Oils
Authors: Knothe Gerhard , Razon Luis F. , Madulid Domingo A. , Agoo Esperanza Maribel G. , de Castro Maria Ellenita G. 
Published: May 2016

AbstractThe fatty acid profiles of six seed oils of the Fabaceae (Leguminosae) family are reported and discussed. These are the seed oils of Centrosema pubescens, Clitoria ternatea, Crotalaria mucronata, Macroptilium lathyroides, Pachyrhizus erosus, and Senna alata. The most common fatty acid in the fatty acid profiles of these oils is linoleic acid with palmitic, stearic, oleic and linolenic acids usually completing the most prominent fatty acids in these species. Long‐chain saturated fatty acids were observed in all oils. Centrosema pubescens and Macroptilium lathyroides exhibited the greatest amounts of long‐chain saturated fatty acids exceeding the amount of stearic acid in these oils. C. pubescens exhibited slightly more that 6 % C24:0 together with some fatty acids >C25 and M. lathyroides approximately 4 % C22:0 and 3 % C24:0. The results are comparatively discussed to previous data on the fatty acid profiles of Fabaceae species.
Penile Traumatic Neuroma: A Late Complication of Penile Dorsal Neurotomy to Treat Premature Ejaculation
Authors: Park Hyun Jun , Kim Tae Nam , Baek Seung Ryong , Lee Kyung Min , Choi Kyung-Un , Park Nam Cheol 
Published: May 2016

Abstract

Introduction
Traumatic neuroma is a reactive process caused by the regeneration of an injured nerve that usually forms a nodular proliferation of small nerve bundles. Penile traumatic neuroma is rare; only a few cases related to circumcision have been reported.

Aim
To report on a case of traumatic neuroma in the penis after selective dorsal neurotomy (SDN) to treat premature ejaculation.

Methods
The penile traumatic neuroma was successfully removed by excision and confirmed by histopathology.

Results
A 55-year-old man who had had several painless, slow-growing nodules on his penis for 2 years presented to our hospital. He had no history of genital trauma, urinary tract infection, or penile surgery, except SDN to treat premature ejaculation. The nodules were excised and the final diagnosis was traumatic neuroma. No recurrence has been detected during 1 year of follow-up.

Conclusion
The main complications of SDN are recurrence of premature ejaculation, pain or paresthesia on the glans penis, and erectile dysfunction. However, no traumatic neuroma has been reported as a complication. We report that a traumatic neuroma can occur after SDN.
