Published: April 2019

We are interested by studying the influence of two drying methods: in the shade and solar energy, on phytochemical composition. For this, we choose the rhizomes of the plant Equisetopsida Asterales, a species that can be found in the poor soil of Provence and Corsica. It prefers dry, sunny places in the Mediterranean. It is native to Southwest Asia, the East and spread in North Africa (Algeria, Morocco, Tunisia, Libya), Australia and the Americas, and Europe (Greece, Italy, France, Portugal, Spain). Equisetopsida Asterales rhizomes are used in Algeria as a traditional cream, which contributes to the disappearance of scars generated by burning. The antimicrobial properties of medicinal and aromatic plants have been known since antiquity. However, it was not until the early 20th century that scientists are beginning to show interest. It is known that the treatment of microbial infection is mainly based on the use of antibiotics, several work is devoted to the study of the antimicrobial power of essential oils.
After some experiences in this work, the important result was obtained, time of Equisetopsida Asterales by solar energy is better than shade; and yield of essential oil extracted is better from the rhizomes dried by solar energy.

An easy-to-operate maize dehusker-sheller machine was constructed from locally available materials with relatively low cost at the premises of DAF Technical Services, Ilorin, Nigeria, between June, 2017 and February, 2018. The construction of the machine was carried out by sizing and marking out of the plate using scriber and cutter. The shaft was smoothened with sand paper and various components were welded; assembling of parts was done by fastener (bolts & nuts). The machine consisted of four units (feeding unit, dehusking – shelling unit, cleaning unit and outlets). Results obtained indicated a mean de - husking efficiency of 58.67%, 57.00%, 54.16 at speed 469 rpm, 309 rpm and 298 rpm respectively. The mean shelling efficiencies were 73.36%, 71.53%, 65 55% at 469 rpm to 298 rpm. And mean through put capacity of 55.90 kg/hr, 41.10 kg/hr and 36.00 kg/hr at speed stated above. Also the mean cleaning efficiencies were 79.97%, 79.77%, 82.23% at speed 469 rpm, 309 rpm and 298 rpm respectively. The mean grain losses were 20.37%, 21.20% and 17.16% using the three speeds stated above. In conclusion, the mean dehusking efficiency, shelling and mean through put capacity performed best at 469 rpm while mean cleaning efficiency and mean grain loss was best at speed 298 rpm.

AbstractWide field‐of‐view (FOV), label‐free, super‐resolution imaging is demonstrated using a specially designed waveguide chip that can illuminate a sample with multicolor evanescent waves travelling along different directions. The method is enabled by a polymer fluorescent film that emits over a broad wavelength range. Its polygonal geometry ensures coverage over all illumination directions, enabling high‐fidelity image reconstruction while minimizing distortion and image blurring. By frequency shifting and iterative stitching of different spatial frequencies in Fourier space, the reconstruction of 2D samples is achieved without distortion over wide FOVs. The fabrication process is facile and compatible with conventional semiconductor‐fabrication methods. The super‐resolution chip (SRC) can thus be produced with high yield, offering opportunities for potential conjunction of super‐resolution techniques integrated optical circuits or for the development of single‐use diagnostic kits.

Published: April 2019

AbstractAtherosclerosis is the root of approximately one‐third of global mortalities. Nanotechnology exhibits splendid prospects to combat atherosclerosis at the molecular level by engineering smart nanoagents with versatile functionalizations. Significant advances in nanoengineering enable nanoagents to autonomously navigate in the bloodstream, escape from biological barriers, and assemble with their nanocohort at the targeted lesion. The assembly of nanoagents with endogenous and exogenous stimuli breaks down their shells, facilitates intracellular delivery, releases their cargo to kill the corrupt cells, and gives imaging reports. All these improvements pave the way toward personalized medicine for atherosclerosis. This review systematically summarizes the recent advances in stimuli‐responsive nanoagents for atherosclerosis management and its progress in clinical trials.

Published: April 2019

AbstractA new polymer electrolyte based on holographic photopolymer is designed and fabricated. Ethylene carbonate (EC) and propylene carbonate (PC) are introduced as the photoinert substances. Upon laser‐interference‐pattern illumination, photopolymerization occurs within the constructive regions which subsequently results in a phase separation between the photogenerated polymer and unreacted EC–PC, affording holographic photopolymer electrolytes (HPEs) with a pitch of ≈740 nm. Interestingly, both diffraction efficiency and ionic conductivity increase with an augmentation of the EC–PC content. With 50 wt% of EC–PC, the diffraction efficiency and ionic conductivity are ≈60% and 2.13 × 10−4 S cm−1 at 30 °C, respectively, which are 60 times and 5 orders of magnitude larger than the electrolyte without EC–PC. Notably, the HPEs afford better anisotropy and more stable electrochemical properties when incorporating N,N‐dimethylacrylamide. The HPEs exhibit good toughness under bending, excellent optical transparency under ambient conditions, and astonishing capabilities of reconstructing colored images. The HPEs here open a door to design flexible and transparent electronics with good mechanical, electrical, and optical functions.

Published: April 2019

AbstractThe temperature (T) dependence of spin–orbit torque (SOT) efficiencies and magnetic properties are investigated in antiferromagnetically coupled Ta/Cu/[Co/Ni]N/TbCo perpendicular composite films. By changing the Co/Ni repetition number N, the magnetization compensation temperature TM can be widely modulated, decreasing from 295 K for N = 0 to below 10 K for N = 2. From temperature‐dependent harmonic Hall measurements, it is shown that damping–like SOT field per current density χDL = HDL/Jac varies in a similar way to the net saturation magnetization MS and reaches a maximum at T = TM, whereas field‐like HFL/Jac is nearly independent with T. The observed slight deviation between χDL and 1/MS versus T curves at reduced temperatures is attributed to the increased spin Hall angle and interfacial spin transparency. It is found that the SOT efficiency ξ varies from −0.04 to −0.06 and even to −0.13 for N = 0, 1 and 2, respectively, suggesting ξ is intensively dependent on the details of the Ta/ferromagnet (FM) interface and the FM layer material. These results provide more insight into the SOT effects for exchange‐coupled perpendicular composite structures, which are valuable for developing high‐performance SOT devices.

Published: April 2019

AbstractFlexible memory devices with optimal tip‐enhanced structures and high density are necessary for data storage devices. Printed electronics combine an efficient manufacturing approach with diverse materials adoptability and multidimensional patterns. However, the precision of the printed structures and the nonuniform of the interfaces restrict the storage density and performance severely. A full printing strategy to fabricate crossbar memory devices with triangular prism–structured Ag microwire electrodes and Ag/silk fibroin conformal interlayers is reported. Based on tip‐enhanced microelectrodes and flexible function layers, these crossbar memory devices show a high ION/IOFF ratio (106 at 1 V) and sufficient retention time (>104 s) under 5 mm curvature radius bending. Devices with 2.5 × 105 bits cm−2 storage density can be printed (103 higher than previously reported results), which enables efficient implement of pattern matching in visual display. This full printing strategy offers efficient fabrication for highly integrated flexible memories and 3D multilayer microdevices.
The D‐dimer assay
Authors: Johnson Eric D. , Schell John C. , Rodgers George M. 
Published: April 2019

AbstractD‐dimer is an indirect marker of fibrinolysis and fibrin turnover; this molecule exhibits unique properties as a biological marker of hemostatic abnormalities as well as an indicator of intravascular thrombosis. D‐dimer is a soluble fibrin degradation product that results from the systematic degradation of vascular thrombi through the fibrinolytic mechanism. Because of this, the D‐dimer serves as a valuable marker of activation of coagulation and fibrinolysis in a number of clinical scenarios. Most commonly, D‐dimer has been extensively investigated for excluding the diagnosis of venous thromboembolism (VTE) and is used routinely for this indication. In addition, D‐dimer has been evaluated for determining the optimal duration of anticoagulation in VTE patients, for diagnosing and monitoring disseminated intravascular coagulation, and for monitoring other conditions in which the patient is at high risk of bleeding or thrombosis. Limitations of the assay include D‐dimer elevation in a constellation of clinical scenarios (age, pregnancy, and cancer) and lack of clinical standardization.

Published: April 2019

AbstractInspired by the enhanced photoluminescence of Au nanoclusters (AuNCs) with a rigid shell, the formation of rigid host–guest assemblies on AuNC surfaces was employed to screen novel electrochemiluminophores with 6‐aza‐2‐thiothymine(ATT)‐protected AuNCs (ATT‐AuNCs) and l‐arginine (ARG) as models for the first time. The rigid host–guest assemblies formed between ARG and ATT on the ATT‐AuNC surface enabled aqueous‐soluble ARG/ATT‐AuNCs with a dramatically enhanced electrochemiluminescence (ECL) compared to ATT‐AuNCs. This includes one cathodic ECL process (−1.30 V) and three anodic ECL processes (+0.78, 0.90, and 1.05 V) in a so‐called half‐scan experiment without a co‐reactant, as well as a 70‐fold enhanced oxidative‐reduction ECL at +0.78 V with tri‐n‐propylamine as a co‐reactant. Importantly, the ECL of the ARG/ATT‐AuNCs is highly monochromatic with an emission maximum around 532 nm and a full width at half‐maximum of 36 nm, which is of great interest for color‐selective ECL assays.
Mid‐point transverse process to pleura block for surgical anaesthesia
Authors: Costache I. 
Published: April 2019

SummaryThe use of ultrasound in regional anaesthesia has expanded our understanding of regional anaesthesia techniques and allowed for the development of novel strategies to achieve blockade of the trunk. Several alternatives to paravertebral block have recently been proposed, but none of these new techniques have yet been shown to provide surgical anaesthesia equivalent to a paravertebral block. This case report describes the successful use of the mid‐point transverse process to pleura (MTP) block as the sole anaesthetic technique for a patient undergoing breast surgery.

Published: April 2019

A heterogeneous Pd‐Cu NWs‐catalyzed expeditious and solvent‐free synthesis of propargylamines via A3‐coupling of aldehydes, alkynes, and amines has been proposed. A wide range of aldehydes, alkynes and amine substrates undergo A3‐coupling to produce propargylamines in good to excellent yields with good functional tolerance, such as that towards alkoxy, hydroxy, C‐X (X = F, Cl, Br) as well as amide and C=C bonds. Furthermore, the catalyst could be recovered easily and reused for at least 5 cycles without showing significant loss of catalytic activity.
Thermal‐oxidative aging performance and life prediction of polyethylene pipe under cyclic and constant internal pressure

Published: April 2019

ABSTRACTTo study the aging characteristic of the polyethylene (PE) 100 pipe under constant and cyclic internal pressure, a new accelerated thermal‐oxidative aging test equipment was developed. Thermal‐oxidative aging behaviors of PE pipe under constant pressure and cyclic pressure were studied in various temperatures (80, 95, and 110 °C) by accelerated aging tests. The tensile test result shows that the fracture strength of PE pipe decreases as the aging time prolongs. Meanwhile, the pipe aged in the higher temperature behaves faster decreasing rate. A faster decreasing rate is also observed under the condition of cyclic pressure, compared to that under constant pressure. The thermal stability of the pipe gradually reduces and the reducing rate under cyclic pressure is higher than that under constant pressure. The result of infrared spectroscopy test suggests that oxygen‐containing groups (i.e., CO) are formed on the surface of PE pipes, indicating that oxidative degradation phenomenon of PE pipes occurs during the aging process. Furthermore, based on the measured result of fracture strength, lifetime prediction models of PE 100 pipe under constant pressure and cyclic pressure are proposed. The result shows that the lifetime of PE 100 pipes obviously decreased under cyclic pressure, and it is 27.96% shorter than that under constant pressure. © 2019 Wiley Periodicals, Inc. J. Appl.

Indo‐Pacific humpback dolphins (Sousa chinensis) in the Moyang River Estuary: The western part of the world's largest population of humpback dolphins
Authors: Li Min , Wang Xinxing , Hung Samuel K. , Xu Youwei , Chen Tao 
Published: April 2019

AbstractInformation gaps from uninvestigated habitats can hinder population assessments and the efficacy of conservation actions for marine mammals, particularly for populations of widely distributed species. The full extent of occurrence of the world's largest (putative) population of Indo‐Pacific humpback dolphins (Sousa chinensis) in the Pearl River estuary (PRE) is not known due to a poor understanding of the western boundary of the population's range. This information gap is the basis of the most critical obstacle for assessing the population's status.To determine the distribution and abundance of the PRE humpback dolphins in the far western portion of its range, systematic line‐transect vessel surveys were conducted in the Moyang River estuary (MRE) during 2013–2015. Photo identification of dolphins and cross‐matching of individual dolphins between different regions were also undertaken to examine individual movement patterns.The abundance of humpback dolphins in the MRE was estimated to be 528 individuals (coefficient of variation: 28.7–50.2%).Cross‐matching of individually identified dolphins from the MRE (present survey area) with those from other survey areas of the PRE showed that dolphins moved frequently across different regions of the PRE, indicating dolphins from both PRE and MRE comprise a single population (which is renamed to be the PRE–MRE population). The western boundary of this population appears to be in the waters on the eastern side of Hailing Island, as dolphins were never observed further west.Supporting around one‐fifth of the PRE–MRE population and providing a quarter of the habitat of the entire PRE–MRE population, the MRE clearly also deserves consideration for greater conservation measures. Strengthening the management with stringent controls over fishing activities in the MRE and establishing a marine protected area in the core habitat are recommended to facilitate better conservation for the entire PRE–MRE humpback dolphin population.
Detecting the undetectable: Characterization, optimization, and validation of an eDNA detection assay for the federally endangered dwarf wedgemussel, Alasmidonta heterodon (Bivalvia: Unionoida)
Authors: Schill William B. , Galbraith Heather S. 
Published: April 2019

Abstract

Environmental DNA (eDNA) assays are valuable tools for monitoring the presence and distribution of cryptic species.
Like many freshwater mussels, the numbers of dwarf wedgemussel, Alasmidonta heterodon, have dwindled and its range has diminished. As of its listing in 1993, only 10–20 locations were known to persist out of the 70 Atlantic slope locations known historically.
A quantitative polymerase chain reaction (qPCR) assay to detect the presence of A. heterodon was developed that uses two probes to accommodate a single‐nucleotide polymorphism (SNP) in the probe‐binding site within the cytochrome c oxidase subunit I (COI) gene. This SNP defines northern and southern major phylogenetic lineages.
The primers match exactly the previously determined COI sequences of 20 dwarf wedgemussel individuals representing Atlantic slope populations from North Carolina, Virginia, Maryland, New York, and New Hampshire. Other than for the qPCR assay described here, these primers can be used for sequencing or metabarcoding to further delineate dwarf wedgemussel populations phylogenetically.
A simple eDNA preparation method is introduced using flocculation to concentrate free DNA in solution as well as cellular material (including shed animal cells, bacteria, viruses, and dissolved DNA).
In addition to the specific application described here, the methodological approaches used in this study are widely applicable to conservation, including, but not limited to, general aquatic biodiversity, phylogenetic studies, and the detection of pathogenic microbes.

Published: April 2019

AbstractA selective, sensitive and high‐throughput liquid chromatography–tandem mass spectrometry bioanalytical method has been developed for the estimation of cycloserine in human plasma, employing cytosine as the internal standard. The extraction of the analyte was facilitated by solid‐phase extraction using 100 μL of human plasma. The separation was carried out on a BDS Hypersil C18 (150 × 4.6 mm, 5 μm) column using a mixture of 0.2% formic acid in HPLC‐grade water, methanol and acetonitrile (70:15:15, v/v/v) as mobile phase at a flow rate of 1.0 mL/min. The method was linear over the range of 0.20–20 μg/mL with r2 > 0.99. Complete validation of the method was performed as per US Food and Drug Administration guidelines and the results met acceptance criteria. Applying the present method, the clinical pharmacokinetics of cycloserine following oral administration of 250 mg cycloserine was studied under fasting conditions. Assay reproducibility was also verified by incurred sample reanalysis.

AbstractThe incidence and death rate of colorectal cancer (CRC) is very high, which brings great need to understand the early molecular events of CRC. These studies demonstrate that long noncoding RNA (lncRNA) plays an important role in the occurrence and development of human cancer. Small nucleolar RNA host gene 15 (SNHG15) was recently identified as a cancer‐related lncRNA. In this study, we aimed to evaluate the function and mechanism of SNHG15 in CRC. The expression of SNHG15 was detected by quantitative RT‐PCR (qRT‐PCR) in CRC tissues and matched noncancerous tissues (NCTs). CCK‐8 assay, colony formation assay, flow cytometric analysis, and nude mouse xenograft mode were used to examine the tumor‐promoting function of SNHG15 in vitro and in vivo. The binding relationship between SNHG15, miR‐338‐3p and the target genes of miR‐338‐3p were screened and identified by databases, qRT‐PCR, dual luciferase reporter assay and western blot. Our results showed that SNHG15 was up‐regulated in CRC tissues compared with paired NCTs (P < 0.0001). High level of SNHG15 expression predicted poor prognosis of CRC (P = 0.0051). SNHG15 overexpression could promote cell proliferation and inhibit cell apoptosis. Animal experiments showed that up‐regulation of SNHG15 promoted tumor growth in vivo. The results of mechanism experiments showed that SNHG15 could bind to miR‐338‐3p and block its inhibition on the expression and activity of FOS or RAB14. In conclusion SNHG15 promotes cell proliferation through SNHG15/miR‐338‐3p/FOS‐RAB14 axis in CRC.
