AbstractBACKGROUNDThe spotted wing drosophila (SWD), Drosophila suzukii (Matsumura), is an invasive vinegar fly with a preference for infesting commercially viable berries and stone fruits. SWD infestations can reduce yields significantly, necessitating additional management activities. This analysis estimates economic losses in the California raspberry industry that have resulted from the SWD invasion.RESULTSCalifornia raspberry producers experienced considerable revenue losses and management costs in the first years following SWD's invasion of North America. Conventional producers have since developed effective chemical management programs, virtually eliminating revenue losses due to SWD and reducing the cost of management to that of purchasing and applying insecticides more often. Organic raspberry producers, who do not have access to the same chemical controls, continue to confront substantial SWD‐related revenue losses. These losses can be mitigated only by applying expensive insecticides registered for organic use and by performing labor‐intensive field sanitation.CONCLUSIONSWD's invasion into North America has caused extensive crop losses to berry and cherry crops in California and elsewhere. Agricultural producers and researchers have responded quickly to this pest by developing management programs that significantly reduce revenue losses. Economic losses are expected to continue to fall as producers learn to manage SWD more efficiently and as new control tactics become available. © 2016 Society of Chemical Industry

RationaleStable isotopes are a prominent tool in animal ecology where data is obtained from analyzing animal tissues, which are typically stored prior to analysis. However, the effect of decomposition on the reliability of stable isotope ratios from animal tissue prior to storage has been seldom studied. Here, we examine the long‐term effects of freezing and decomposition of animal tissue on δ13C and δ15N values across three different aquatic species of varying lipid content.MethodsRinged seal, lake trout and Greenland shark muscle were divided into different treatment groups and analyzed for their δ13C values, carbon content (%C), δ15N values, and nitrogen content (%N) at specific time intervals. The intervals included days 0, 128 and 700 for the frozen storage treatment and at days 0, 1, 2, 4, 8, 16, 32, 64, 128 and 256 for the tissue decomposition treatment in open and closed vials at room temperature.ResultsThe difference in δ13C and δ15N values between the control and days 128 and 700 for the frozen treatment was minimal and not significant for any species. Generally, significant decreases in carbon (%C) and nitrogen (%N) content and significant increases (>0.5‰) in δ13C and δ15N values occurred for muscle of each species left to decompose for 256 days, probably due to the preferential uptake of lighter isotopes during decomposition by microbes. However, the magnitude of change in the δ13C and δ15N values up to 8 days in both treatments was low (generally ≤0.1‰) and not significant across most species.ConclusionsFreezing for extended time periods (up to 700 days) is a viable storage technique for stable isotope analysis of aquatic animal muscle tissue across a range of lipid contents. Muscle tissue left to decompose at room temperature showed no significant change in δ13C and δ15N values after 8 days, and such tissues would still be reliable for ecological interpretations. However, caution should be used for decomposed tissue for >8 days as the δ13C and δ15N values will probably be artificially high. Copyright © 2016 John Wiley & Sons, Ltd.

ABSTRACTObjectivesAs postnatal identification of accelerated idioventricular rhythm (AIVR) relies on specific electrocardiographic patterns, prenatal diagnosis of this condition is challenging and its true incidence is unknown. The objectives of this study were to evaluate the performance of prenatal ultrasonography in identifying intrauterine cardiocirculatory events linked to specific electrocardiographic signs of postnatal AIVR, including left or right ventricular origin, and to assess the prenatal prognosis of this arrhythmia.MethodsWe reviewed Doppler tracings from the superior vena cava/ascending aorta (SVC/Ao), ductus venosus (DV), ductus arteriosus (DA) and aortic isthmus (AoI), as well as simultaneous M‐mode recordings of septal and left ventricular wall motions of fetuses diagnosed with AIVR from January 2004 to December 2014.ResultsThree cases of AIVR were identified among 27 912 fetuses. SVC/Ao Doppler flow recordings revealed atrioventricular dissociation (ventricular rates within 20% of atrial rates) in all three fetuses and episodes of isorhythmic atrioventricular dissociation in one, while M‐mode confirmed normal left ventricular shortening fraction in all cases. Fusion beats were observed on AoI tracing in one fetus, while simultaneous recordings of AoI and DA revealed signs of right bundle branch block in one case and left bundle branch block in the other two. On DV Doppler recordings, retrograde a‐waves in the presence of simultaneous atrial and ventricular contractions were observed in all three fetuses, leading to an increase in central venous pressure in all and hydrops fetalis in two cases without evidence of ventricular dysfunction.ConclusionsEchocardiographic criteria required for postnatal diagnosis of AIVR can be documented in utero using specific ultrasonographic approaches. During fetal life, AIVR may not be a benign entity. Hydrops fetalis is frequently associated with AIVR because of increase in central venous pressure related to simultaneous atrioventricular contractions; thus, the ultrasonographic investigation protocol of fetuses with unexplained hydrops fetalis should aim at ruling out AIVR and include Doppler flow recordings in SVC/Ao, DV, AoI, DA and umbilical vein.

ABSTRACTObjectivesCervical pregnancy (CP) is a rare type of ectopic pregnancy. While methotrexate (MTX) is generally the first‐line method of choice for clinically stable women, there is still no consensus on the most appropriate treatment for this abnormal pregnancy. The aim of this study was to investigate the efficacy of a single local MTX injection under transvaginal ultrasound guidance for the initial treatment of CP and to assess post‐treatment fertility.MethodsWe reviewed retrospectively 15 patients with CP treated with local MTX injection under transvaginal ultrasound guidance. In all patients, the serum human chorionic gonadotropin (hCG) levels were monitored and the gestational sac was evaluated using ultrasonography after treatment. Magnetic resonance imaging (MRI) was performed as necessary. We evaluated the patients' clinical characteristics and clinical course after treatment, the efficacy of the treatment and the post‐treatment fertility in patients desiring subsequent pregnancy.ResultsThe median estimated gestational age at the time of MTX injection was 6 + 2 (range, 5 + 2 to 11 + 0) weeks. All 15 patients were treated successfully, without the need for blood transfusion or surgical procedures; however, three patients required an additional local MTX injection due to a poor decline in serum hCG level following the initial injection, while one patient required uterine artery embolization due to persistent vaginal bleeding and an enlarging gestational sac with blood vessels visible on contrast‐enhanced MRI. The mean time following initial MTX injection for hCG normalization was 43.8 (95% CI, 33.3–54.3) days and for resumption of menses was 68.4 (95% CI, 51.9–84.9) days. Seven of the 10 women desiring subsequent pregnancy following treatment had uneventful pregnancy, one became pregnant but miscarried spontaneously at 8 weeks of gestation, one was treated by laparoscopic surgery after diagnosis of a tubal pregnancy and one did not conceive.ConclusionsA single, ultrasound‐guided, local MTX injection is apparently effective for the treatment of CP without the need for concomitant procedures or surgical intervention. Furthermore, this conservative technique both preserves fertility and allows for the possibility of subsequent uneventful pregnancy. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.
Landscape structure and agricultural intensification are weak predictors of host range and parasitism rate of cereal aphids
Authors: Hawro Violetta , Ceryngier Piotr , Kowalska Anna , Ulrich Werner 
Published: December 2016

AbstractProportions of specialist and generalist primary parasitoids have been described by the resource breadth and the trade‐off hypothesis. These alternative hypotheses predict either decreased or increased, respectively, parasitism rate of shared aphid species by specialist parasitoids. We tested both hypotheses and the confounding effects of landscape structure and agricultural intensification (AI) using extensive samplings of aphids and their parasitoids in Polish agricultural landscapes. Abundances, species composition of aphids, primary parasitoids, and parasitism rate of aphids by specialists and generalist parasitoids were analysed. Contrary to our expectations we found equally decreased parasitism rates by both types of primary parasitoids at higher aphid densities and thus proportion of specialists to generalists did not change with increasing host density. In line with the resource breadth hypothesis, specialist parasitoids had always lower abundances and parasitism rates than generalist parasitoids. Landscape diversity and agricultural intensification did not influence the host‐parasitoid population dynamics. We speculate that these contrasting results could be caused by the additional density effects of secondary parasitoids. We conclude that simplistic two‐trophic‐level population models are not able to fully describe the complex dynamics of trophic networks. We also argue that agricultural intensification has lower effects on abundance and effectiveness of parasitoids than predicted by respective predator–prey models and empirical studies performed in controlled and artificial conditions.

AbstractIntroductionChanges in intrinsic functional connectivity (iFC) have been reported at various stages of the Alzheimer's disease (AD) spectrum. We aimed to investigate such alterations over a variety of large‐scale intrinsic brain networks (iBNs) across the spectrum of amyloid β positivity and uncover their relation to cognitive impairment.MethodsEight iBNs were defined from resting‐state functional magnetic resonance imaging data. In amyloid β–positive healthy subjects, prodromal, and AD patients (N = 70), within‐network iFC (intra‐iFC) and between‐network iFC (inter‐iFC) were correlated with scores of cognitive impairment.ResultsAcross all iBNs, a general degradation in intra‐iFC along the scale of cognitive impairment severity was found. Only subtle changes in inter‐iFC were identified.DiscussionAcross the AD spectrum, changes in iFC that are strongly related to cognitive impairment occur within an extensive variety of networks.

Abstract
Cr-V-bearing rocks of the Sludyanka metamorphic complex in the Southern Baikal area contain accessory niobian rutile with Nb contents unusually high for metamorphic rocks (10–12 to 20–25 wt.% Nb2O5, or, occasionally, up to 36–37 wt.%). Incorporation of Nb5+ into the rutile structure is balanced by Cr3+ and V3+, which reach 16 wt.% Cr2O3 and 8 wt.% (or, rarely, up to 20 wt.%) V2O3. The distribution of Nb, Cr, and V in rutile is very uneven, down to the microscale. It does not depend on PT conditions, being rather controlled by crystallization kinetics of minerals competing with rutile in the paragenesis.
Basaltic magmatism and strike-slip tectonics in the Arctic margin of Eurasia: evidence for the early stage of geodynamic evolution of the Amerasia Basin
Authors: Shipilov E.V. 
Published: December 2016

Abstract
Interpretation of geological and geophysical data from several regions in the Arctic continental margin of Eurasia which differ in structure and tectonic settings shed new light on the early history of the Arctic Ocean (Canada Basin) opening. Many issues of regional tectonics and geodynamics become clear due to evidence of Late Mesozoic magmatism within the continental margins of the Barents and East Siberian Seas and strike-slip tectonics in the Chukchi shelf. Interpretation analysis is applied to reconstruct the formation of structures in the Amerasia Basin during the Arctic Ocean initiation.

Abstract
A superlarge gold-ore stockwork of the Vasil’kovskoe deposit (with gold resources of more than 380 tons) is located at the contact of porphyroblastic granodiorites and diorites in northern Kazakhstan. The specifics of the Vasil’kovskoe deposit is a wide occurrence of gray (so-called ore) gold-bearing quartz, which, together with white quartz, composes quartz–sulfide veins and veinlets in the stockwork. Based on thermobarogeochemical and isotope-geochemical data, we have established that gray quartz and arsenopyrite of the deposit formed with the participation of K–Na–Mg–Cl-containing aqueous CO2–hydrocarbon fluids at 250–550 ºC, 0.1–2.5 kbar, and salinity of 7.0–22.5 wt.% NaCl equiv. (seldom, &gt;30–40 wt.% NaCl equiv.). The cyclic recurrence of parameter fluctuations was accompanied by the deposition of gold, which led to the formation of gold-rich veinlet ores in the stockwork core. White quartz formed at lower temperatures, 120–310 ºC, and 0.2–1.0 kbar, with the participation of Ca–Na–Cl-containing fluids with salinity of 2.0–11.0 wt.% NaCl equiv. In addition to H2O and CO2, hydrocarbons and their derivates (paraffins, olefins, arenes, alcohols, ethers, aldehydes, ketones, and carboxylic acids) as well as nitrogen-containing (C2H3N, C3H9N, C7H5N, and C8H5NO2) and sulfur-containing (CS2, COS, SO2, C2H6S2, etc.) compounds (indicators of reducing conditions) were involved in the ore formation. The sulfur isotope composition of sulfides (δ34S = +5.7 to + 11.8‰) and the carbon isotope composition of CO2 in fluid inclusions in gray (δ13C = –2.1 to –4.6‰) and white (δ13C = –11.0 to –21.4‰) quartz as well as its positive and negative anomalies of Eu point to the crustal source of the fluids. The gray color of quartz is due to abundant CO2–hydrocarbon-containing inclusions, carbon particles, and sulfides. Crystallization of ore-hosting granodiorites happened in the period from 490.0 ± 4.4 to 443.5 ± 4.1 Ma. The age of the areal K-feldspathization of granodiorites, preceding the ore formation, is 375.2 ± 3.7 Ma. Formation of gold-including parageneses took place in the period from 311.7 ± 6.4 to 279.2 ± 2.5 Ma, i.e., lasted no less than 30 Myr.

Abstract
We analyze the history of oil discoveries of different sizes in two centers of the Volga–Ural petroleum province, the Republics of Bashkortostan and Tatarstan, and demonstrate the important role played by Academicians I.M. Gubkin and A.A. Trofimuk in these discoveries. Special focus is placed on the analysis of small and smallest oil fields and the sequence of their discovery. It was shown that all discoveries in Tatarstan and Bashkortostan were the result of the exploration filter. It was also shown that the establishment and support of small oil businesses in Bashkortostan and Tatarstan can be an importance means of the facilitating development of small and smallest fields. The study discusses the role of small independent oil companies in the regional oil production, considers priority areas of state and regional and legal support of small and medium oil enterprises, and presents oil production forecast for Bashkortostan and Tatarstan.

Bone morphogenetic protein 9 (BMP-9) has been demonstrated to improve glucose homoeostasis in diabetic mice. However, no report has demonstrated the relationship of circulating BMP-9 levels with insulin resistance (IR) or Type 2 diabetes mellitus (T2DM) in humans. The objective of the present study was to investigate the relationship between BMP-9 and IR in cross-sectional and interventional studies. Circulating BMP-9 levels were analysed by ELISA in 280 well-characterized individuals. Two-hour oral glucose tolerance test (OGTT) and euglycaemic–hyperinsulinaemic clamp (EHC) were performed in 20 healthy subjects. Acute IR was induced by lipid infusion for 4 h in 20 healthy volunteers. Real-time (RT)-PCR and Western blotting were used to assess mRNA and protein expression of BMP-9. The effect of a glucagon-like peptide-1 (GLP-1) receptor agonist (PEX168) on circulating BMP-9 was investigated in a 24-week treatment trial. Circulating BMP-9 levels were significantly higher in healthy subjects than in newly diagnosed patients with T2DM. Circulating BMP-9 negatively correlated with HbA1c, fasting blood glucose (FBG), OGTT, the area under the curve for glucose (AUCglucose) and homoeostasis model assessment of insulin resistance (HOMA-IR). Multivariate regression analyses showed that BMP-9 levels were independently associated with non-esterified fatty acid (NEFA) and AUCglucose. Both hyperinsulinaemia and lipid infusion decreased circulating BMP-9 levels. BMP-9 mRNA and protein expressions were significantly decreased in muscle and adipose tissues of T2DM patients. In the placebo treated group, BMP-9 levels continued to decline over time, whereas in the PEX 168 treated groups BMP-9 levels remained stable. Our data suggest that BMP-9 is likely to play an important role in IR in humans.

AbstractOver the past few decades, it has been recognized that traumatic brain injury (TBI) may result in various movement disorders. However, moderate or mild TBI only rarely causes persistent post-traumatic movement disorders. In the present report, we describe a case of secondary tremor due to a mild head injury with a transitory loss of consciousness. A 26-year-old man developed an isolated rest tremor of the hands and legs without other neurologic signs. The interval between the head trauma and the onset of the symptoms was 4 months. Neuroimaging studies reveled gliosis in the lentiform nucleus. Haloperidol administration resulted in tremor reduction. A rest tremor, similar to essential tremor, can be a rare complication of head trauma. Haloperidol may be an effective and safe treatment modality for post-traumatic tremor. Further studies are needed to clarify the optimal drug for the treatment of post-traumatic tremor.

Published: December 2016

Significance
Rapid anthropogenic trait changes in fish stocks is a highly publicized ocean conservation issue, yet the relative contributions of evolutionary and ecological dynamics are unknown. We present an integrative empirically based simulation model to determine the role of these contributions in the world’s largest cod stock. We quantitatively evaluate predictions with different density-dependent growth models using historical stock-specific data. The amount of evolution required for explaining observed maturation trends is small, yet with weakly density-dependent growth, critical for preventing stock collapse. The role of evolution in explaining trends is diminished when density-dependent growth is present. Our study reveals how interactions among evolution, ecology, and fisheries influence stock dynamics and harvest sustainability, emphasizing the need for integrated approaches to fisheries management.

SignificanceDepression is a seriously disabling disorder, twice as common in women as in men. Lack of efficacy of existing pharmacotherapies in subsets of patients has led to an intensive search for new targets for antidepressant development, including receptors for neuropeptides such as galanin (GAL). In this study, we explore GAL and its three receptors, GAL1–3, comparing postmortem brain regions from depressed suicide patients and controls. Using quantitative PCR and bisulfite pyrosequencing, we report significant changes in the transcript and DNA methylation levels ofGALand galanin receptor 3 (GALR3) in the locus coeruleus and dorsal raphe nucleus, two regions important for mood regulation. Our findings suggest GAL3involvement in depressive disorder, making it a possible drug target for this disease.
