Authors: Chung Jae-Ho , Baek Si-Ook , Park Ho-Jin , Lee Byung-Il , Park Seung-Ha , Yoon Eul-Sik 
Published: January 2019

Background When performing lymphovenous anastomosis, it is sometimes difficult to find venules in the proximity of an ideal lymphatic vessel that have a similar diameter to that of the lymphatic vessel. In this situation, larger venules can be used.
Methods The authors evaluated the efficacy of and patient satisfaction with lymphovenous bypass with sleeve-in anastomosis. Between January 2014 and December 2016, we performed this procedure in 18 patients (eight upper extremities and 10 lower extremities) with secondary lymphedema. Lymphovenous bypass with sleeve-in anastomosis was performed under microscopy after injecting indocyanine green dye. The circumferential diameter was measured before lymphovenous bypass and at 1, 2, and 6 months after the procedure. An outcomes survey that included patients’ qualitative satisfaction with lymphovenous bypass was conducted at 6 months postoperatively.
Results Almost all patients showed quantitative improvements after surgery. The circumferential reduction rate in patients with stage II lymphedema of both the upper and lower extremities was significantly greater than in their counterparts with stage III/IV lymphedema. The circumferential reduction rate was lower in lower-extremity patients than in upper-extremity patients.
Conclusions Lymphovenous bypass surgery with sleeve-in anastomosis in lymphedema patients is beneficial, and appears to be effective, when adequately-sized venules cannot be found in the proximity of an ideal lymphatic vessel.

Authors: Álvarez-Vázquez Carmen , Bek Jiří , Wagner Robert H. 
Published: January 2019

Bergeria dilatata (Lindley & Hutton) Alvarez-Vazquez & Wagner, a Middle Pennsylvanian lycopsid, is redescribed based on type material from England as well as 586 specimens from the Peñarroya-Belmez-Espiel Coalfield, Cordoba province, southern Spain. The species is characterized by longer than broad, smooth leaf cushions showing false leaf scars, and the presence of perennial, long, entire, single-veined leaves. A complete synonymy is presented and 21 new species (two of them with doubts), previously placed in 6 different genera, have been synonymized. Associated Flemingites-type cones, determined as Flemingites russelianus, yielded in situ spores of the Lagenoisporites rugosus type and microspores of the Microspinosporites type.
Conodont association of the Bashkirian-Moscovian boundary interval of the Donets Basin, Ukraine
Authors: Nemyroska Tamara I. , Hu Keyi 
Published: January 2019

Ten sections spanning the Bashkirian-Moscovian boundary interval were studied in the Donets Basin. Six of them contain most representative conodont and foraminifer associations. In this paper we focused on three the most complete sections that include stratigraphically important conodont species, which belong to the Declinognathodus, Idiognathoides, Idiognathodus, Neognathodus, “Streptognathodus”, Mesogondolella and Diplognathodus genera. The majority of those species are widely distributed, which makes the correlation to other areas reliable. Two biotic events in conodont evolution were discovered in these sections. Two conodont lineages established here are considered as potential markers for the definition of the lower boundary of the Global Moscovian Stage: D. marginodosus – D. donetzianus and Id. sulcatus sulcatus – Id. postsulcatus. The conodonts D. donetzianus and Id. postsulcatus, both proposed before as potential markers for the de? nition of the GSSP at the Bashkirian-Moscovian boundary, are described and compared to those from the other areas. The entry of D. donetzianus is updated and con? rmed to the top of the limestone K1 in both sections, the Zolota Valley and the Malo-Mykolaivka sections. The other proposals for the de???? nition of the lower Moscovian boundary by conodonts are discussed. Three conodont zones characterize the Bashkirian-Moscovian boundary interval. These are, in ascending order: the Id. tuberculatus – Id. fossatus Zone and D. marginodosus Zone from the upper Bashkirian, and D. donetzianus Zone from the lower Moscovian. They were recently described and shortly given in this paper.
Phylogenetic analysis of Gondwanan basal eusauropods from the Early-Middle Jurassic of Patagonia, Argentina
Authors: Holwerda Femke M. , Pol Diego 
Published: January 2019

Gondwanan Jurassic non-neosauropod eusauropods are key for the understanding of sauropod evolution, although their phylogenetic interrelationships remain poorly understood. However, following the revision of the holotype of a key taxon from the early Middle Jurassic Cañadón Asfalto Formation Patagonia, Argentina, Patagosaurus fariasi, the phylogenetic a ? nities need to be tested with new osteological information gathered during the redescription of the holotype of Patagosaurus. A new phylogeny presented here shows a close a ? liation of Patagosaurus with Cetiosaurus from the Middle Jurassic of the UK. The close relationship of Patagosaurus with Barapasaurus, often found in previous phylogenies, was not recovered here. Instead, Patagosaurus is retrieved as more derived than most Early and Middle Jurassic sauropods, although more basal to Mamenchisaurus, Omeisaurus, turiasaurians, and neosauropods. Another sauropod taxon found together with Patagosaurus, Volkheimeria, is retrieved several nodes more basal than the former, which shows, together with evidence of several other sauropod taxa in the Cañadón Asfalto Formation, that a high evolutionary diversity existed in Southwest Gondwana in the early Middle Jurassic, a pattern which is also seen in fossil groups other than sauropods (e.g., theropods).
Fosildiagénesis del anélido Rotularia spirulaea (Lamarck, 1818) (Polychaeta, Serpulidae) en el Eoceno del dominio pirenaico occidental
Authors: Elorza Javier , Astibia Humberto 
Published: January 2019

The presence of the fossil polychaete Rotularia spirulaea (Lamarck, 1818) in Eocene deposits (middle Lutecian – upper Bartonian and (?) Priabonian) belonging to the western Pyrenean Domain is verified. In this paper, a fossildiagenetic study has been carried out. Fossils from three areas, corresponding to diff erent depositional settings, have been analysed. In area 1, sediments of the Ardanatz Sandstone and Ilundain Marls formations [Pamplona Basin and adjoining areas (Navarre)], were sampled. Here, the specimens of R. spirulaea were not substantially affected by taphonomic reworking and the original microstructure of the carbonate tube is preserved. The test consists of a thick external shell layer, composed of three zones in succession, and another extremely thin inner shell layer. The lumen of the tube is filled in by fine-grained sediment and/or calcitic cement. In area 2 , which includes the town of Anderatz and several outcrops of the Urbasa mountain range (Navarre), Urbasa-Andia Formation and overlying deposits, as well as in area 3 , located on the upper part of the calciclastic fl ysch of Punta Galea (Biscay), fossils are included in sediments deposited in high-energy environments. In this case, the microstructure of R. spirulaea tube is not completely recognized due to intense, early diagenetic silicifi cation aff ecting the tests. The lumen is filled in with fragments of foraminifera and calcareous algae, quartz-feldespathic sediment and cemented by calcite. Therefore, in zones 2 and 3 the fossildiagenetic processes are substantially different from those recognized in zone 1.

Published: January 2019

The apple (Malus domestica Borkh) originally evolved to require temperatures below 7.2 °C for the induction of budding and flowering. In Brazil, breeders have overcome the climate barrier and developed the cultivars Anabela, Julieta, Carícia, and Eva, with low chilling requirements and good yield characteristics. These cultivars are grown in many warmer climate countries in South America, Africa, and the Middle East. The apple germplasm collection that originated these cultivars has several genotypes with pedigrees for a low chilling requirement. Knowledge of the variability and genetic relationships among these genotypes may be useful in the development of superior new cultivars. In this work, we first selected the best ISSR (inter-simple sequence repeat) primers for genetic studies in apple, and then we used the selected primers to evaluate the genetic variability of the apple germplasm collection at the Instituto Agronômico do Paraná. The evaluation of 42 ISSR primers in 10 apple genotypes allowed us to select the best nine primers based on the polymorphic information content (PIC) and resolving power (RP) indexes. The primer selection step was robust since the dendrogram obtained with the nine selected primers was the same as the one obtained using all 26 polymorphic primers. Primer selection using PIC and RP indexes allowed us to save about 60% of time and costs in the genetic variability study. The nine ISSR primers showed high levels of genetic variability in the 60 apple genotypes evaluated. The relevance of the primer selection step is discussed from the perspective of saving time and money in germplasm characterization. The high genetic variability and the genetic relationships among the genotypes are discussed from the perspective of the development of new apple cultivars, mainly aiming for a low chilling requirement that can better adapt to current climatic conditions or those that may arise with global warming.

Published: January 2019

AbstractHerein, hollow multishelled structure (HoMS) of Co3O4–CeO2−x nanocomposites with controllable molar ratio of Co and Ce elements is synthesized by a general strategy sequential templating approach (STA) with a facile and efficient electrostatic spray process. As a catalyst of carbon monoxide (CO) catalytic oxidation, Co3O4–CeO2−x (Co/Ce = 4/1) HoMS achieves good catalytic activity (complete conversion temperature is 166.9 °C) and stability (100 h). This performance is attributed to synergistic effects between the two components. The combination of Co3O4 and CeO2 not only generates more interfaces of Co3O4–CeO2−x, which is more favorable for the activation of oxygen, but also improves the oxidizability of Co3O4 as well as the capacity of oxygen storage of CeO2. In addition, the relatively larger effective specific surface area of the HoMS can provide more active sites, while the unique structure of HoMS can facilitate gas diffusion and maintain structural stability.

AbstractThe p‐type semiconducting copper oxides (CuO and Cu2O) are promising materials for gas sensors, owing to their characteristic oxygen adsorption properties and low operation temperature. In this study, the sensing performance of a CuO‐based chemiresistor is significantly enhanced by incorporating Ag nanoparticles on high‐resolution p‐type CuO/Cu2O nanopattern channels. The high‐resolution CuO/Cu2O/Ag nanochannel is fabricated using a unique top‐down nanolithographic approach. The gas response (ΔR/Ra) of the CuO/Cu2O/Ag gas sensor increases by a maximum factor of 7.3 for various volatile organic compounds compared with a pristine CuO/Cu2O gas sensor. The sensors exhibit remarkable sensitivity (ΔR/Ra = 8.04) at 125 parts per billion (ppb) for acetone analytes. As far as it is known, this is the highest sensitivity achieved for p‐type metal oxide semiconductor (MOS)‐based gas sensors compared to previous studies. Furthermore, the outstanding gas responses observed in this study are superior to the most of n‐type MOS‐based gas sensors. The high sensitivity of the sensor is attributed to i) the high resolution (≈30 nm), high aspect ratio (≈12), and ultrasmall grain boundaries (≈10 nm) of the CuO/Cu2O nanopatterns and ii) the electronic sensitization and chemical sensitization effects induced by incorporating Ag nanoparticles on the CuO/Cu2O channels.

Published: January 2019

AbstractShaping ceramics into complex 3D geometries is desirable yet challenging, particularly those with structural hierarchy spanning different length scales. A mechano‐plastic pyrolysis process that overcomes this limitation is reported. In addition to taking advantage of the moldability of organic polymers, the process uniquely incorporates mechano‐plasticity via dynamic covalent bond exchange for reconfiguring the shape of a preceramic polymer. The combined steps result in simultaneous shape control at both micro‐ and macro‐scales. Further pyrolysis leads to complex ceramic structures that are otherwise difficult to produce. To enable this process, rational design of the polymer network is required to satisfy an unusual combination of mechano‐plasticity and pyrolysis. Overall, the process offers an avenue for efficient fabrication of hierarchical 3D ceramic structures suitable for engineering applications.

AbstractUnderstanding nanoscale molecular order within organic electronic materials is a crucial factor in building better organic electronic devices. At present, techniques capable of imaging molecular order within a polymer are limited in resolution, accuracy, and accessibility. In this work, presented are secondary electron (SE) spectroscopy and secondary electron hyperspectral imaging, which make an exciting alternative approach to probing molecular ordering in poly(3‐hexylthiophene) (P3HT) with scanning electron microscope‐enabled resolution. It is demonstrated that the crystalline content of a P3HT film is reflected by its SE energy spectrum, both empirically and through correlation with nano‐Fourier‐transform infrared spectroscopy, an innovative technique for exploring nanoscale chemistry. The origin of SE spectral features is investigated using both experimental and modeling approaches, and it is found that the different electronic properties of amorphous and crystalline P3HT result in SE emission with different energy distributions. This effect is exploited by acquiring hyperspectral SE images of different P3HT films to explore localized molecular orientation. Machine learning techniques are used to accurately identify and map the crystalline content of the film, demonstrating the power of an exciting characterization technique.

Published: January 2019

AbstractIntroductionTo compare the duration of vacuum and forceps delivery in relation to ultrasound assessment of fetal head position and station.MethodsA prospective single‐centre cohort study in nulliparous women at term with prolonged second stage of labour. Fetal head position was determined using transabdominal ultrasound and station as head‐perineum distance (HPD) from transperineal ultrasound prior to an instrument. The primary outcome was duration of vacuum and forceps to vaginal delivery and was analysed as survival expressed by hazard ratio (HR). Secondary outcomes were delivery mode and immediate neonatal outcome.ResultsIn the study population of 54 women, the primary instrument was vacuum for 36 and forceps for 18. Four women were delivered by Caesarean section. Estimated median duration for forceps deliveries was 5 min (95% CI 4.0–6.0) vs. 9 min (95% CI 7.3–10.6) for vacuum deliveries (P = 0.17; Log‐rank test). The HR for vaginal delivery was 2.02 (95% CI 1.04–3.91, P = 0.038) after adjusting for HPD, maternal age and BMI. OP position had minor influence on the primary outcome (HR changed from 2.02 to 2.08). The first instrument failed in 11/31 (35.5%) where HPD > 35 mm vs. 2/21 (9.5%) where HPD ≤ 35 mm (P < 0.05). There were no cases of Apgar score <7 at 5 min or umbilical artery pH < 7.1.ConclusionIn prolonged second stage, delivery with forceps was achieved more quickly than by vacuum when matched for ultrasound determined head station. Irrespective of which was the primary instrument, the failure rate was greater at higher head stations.

Abstract

Anthropogenic activities have resulted in declines in many marine turtle populations. Their complex life cycle (e.g. female philopatry, hatchling migration, adult movements between breeding and foraging areas) makes it difficult to fully understand some of the biological implications of human impacts on their populations, but genetic tools can play a major role in understanding population dynamics and thus improve conservation and management strategies.
Using the mitochondrial DNA control region, this study examines the composition, population structure, and connectivity between rookeries and foraging aggregations, in addition to their relationship with Atlantic rookeries and foraging areas of the hawksbill turtle in the Yucatan Peninsula.
Haplotype composition of rookeries showed EiA22, EiA39, and EiA41 as endemic haplotypes and revealed a segregation between the Gulf of Mexico and the Yucatan and Quintana Roo rookeries, defining two management units. Foraging aggregations present 15 haplotypes, some common for Atlantic and others for Mexican rookeries. Considering the Gulf of Mexico versus the Mexican Caribbean, significant population genetic structure was revealed, inferring a differential recruitment of hawksbill turtles.
Rookery‐centric mixed‐stock analysis reveals a high contribution of Mexican turtles to local foraging aggregations, principally in the Gulf of Mexico. Foraging‐ground‐centric mixed‐stock analysis showed that the Gulf of Mexico foraging aggregation is predominantly composed of individuals from local rookeries, whereas Mexican Caribbean foraging groups have a mixed composition with individuals from Barbados, Brazil, and Puerto Rico rookeries. The connectivity between rookeries and foraging aggregations suggests that the ocean currents and swimming behaviour influence the distribution of hawksbill turtles.
Our results highlighted the importance in identifying management units in nesting and foraging areas to develop monitoring and management programmes at appropriate geographic scales. In addition, understanding turtle habitat connectivity will allow for prioritized conservation actions considering particular threats, emphasizing the need for both national and international collaboration for conservation of this endangered species.

Published: January 2019

AbstractAs a pest on the Qinghai‐Tibet Plateau, Gynaephora qinghaiensis causes severe damage to grassland vegetation and its pupae are also natural hosts of
Thektogaster sp. To successfully parasitize, endoparasitoids generally introduce or secrete multiple parasitic factors into the host body during the spawning stage to suppress the host immune response. To study the parasitic effects of
Thektogaster sp. on
G. qinghaiensis, a transcriptome analysis of immune‐related genes in parasitized and nonparasitized
G. qinghaiensis pupae was performed. A total of 371,260,704 clean reads were assembled into 118,144 unigenes with an average length of 884.33 base pairs. Of these, 23,660 unigenes were annotated in at least one database and 94,484 unigenes were not annotated in any databases. These findings indicated that the majority of the genetic resources (79.97% of all unigenes) in
Gynaephora should be further explored. Parasitization significantly affected the transcriptional profile of
G. qinghaiensis pupae. The present study identified 12,322 differentially expressed genes and 57 immune‐related genes were identified in parasitized
G. qinghaiensis pupae. Most immune‐related genes were downregulated, potentially resulting from the inhibitory effect of
Thektogaster sp. on
G. qinghaiensis pupae after parasitization. Overall, the transcriptome analysis sheds valuable light on the molecular mechanisms of
G. qinghaiensis parasitization by
Thektogaster sp. and promotes the development of novel biocontrol strategies for
Gynaephora based on immune defense.

Published: January 2019

AbstractThis paper presents a robust fault tolerant control for an induction motor in presence of inter‐turn short‐circuit fault. The control strategy is based on Backstepping approach and high order sliding mode observer. That ensures a high‐performance control and a good dynamic in presence of inter‐turn short‐circuit fault. The stability of the Backstepping control is proved by Lyapunov theory. A high order sliding mode observer is used for rotor flux estimation. The performances of the fault tolerant control scheme will be examined via numerical simulation and validated through hardware implementation using MATLAB/Simulink with dSpace signal card. The analysis' results show the robustness of the proposed method for the tolerance of the inter‐turn short‐circuit fault.

Published: January 2019

AbstractPolyhydroxyalkanoates (PHAs) are one of the most important biopolyesters produced by vast number of microorganisms that exist in the environment. PHAs gained much attention due to its inherent biodegradable and biocompatible ability along with its physicochemical properties, which are similar to those of conventional petroleum‐based plastics. In the present study, PHA producing bacterial strains was isolated from earthworm. Initially, four bacterial strains were selected based on the intensity of fluorescence from 80 non‐clonal isolates. Bacillus thuringiensis (B.t.) E101 was identified as the bacterium producing highest yield of PHA (3.6 ± 0.04 g L−1) through biochemical and molecular techniques such as 16S rRNA gene sequence analysis. Growth parameters such as carbon, nitrogen sources, and incubation time were optimized with respect to higher PHA production. Both qualitative (Fourier transform infrared spectroscopy and nuclear magnetic resonance) and quantitative (GC–MS) characterizations revealed that the polymer produced by B.t.E101 contains the characteristic peaks for poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) copolymer. This is the first report for the occurrence, successful isolation, and characterization of PHA producing Bacillus sp. from earthworm.
