Introduction: The minimally invasive approach has become the method of choice for treating most benign abdominal diseases that require surgery. However, it is obvious that laparoscopic procedures are not risk free. The aim of this study was to evaluate the prevalence of intra abdominal adhesions underneath umbilical scar following laparoscopic sterilization, in patients who are undergoing abdominal surgeries.
Materials and Methods: The present study was a hospital based prospective observational study conducted in the Department of Surgery, Dr Rajendra Prasad Government Medical College (Dr. RPGMC), Kangra at Tanda (HP). The study group consisted of patients admitted to department of surgery during a period of one year and who fulfilled inclusion criteria. During intraoperative period, they were examined for presence or absence of adhesions at the site of previous laparoscopic sterilization scar at Periumblical area.
Results: Total of 60 patients were taken in this study. Two out of 60 (3.3%) patients had adhesions underneath previous Laparoscopic Sterilization scar around umbilicus and adhesive structure was omentum in both cases.
Conclusion: Adhesion formation is expected in any abdominal surgery whether open or laparoscopic surgery. In our study only 3.3% of patients had adhesions underneath previous laparoscopic sterilization scar in periumblical region. Therefore umbilical port can be considered for re-entry of index port in next laparoscopic surgery, in patients with history of laparoscopic surgery through umbilical region.

Background and Objective: Unproductive soil has been a major problem to farmers, recent interest in the use of a stable organic manure (biochar) as soil amendment and poultry manure to increase soil fertility is also increasing. Hence, the experiment was conducted to assess the condition of poultry manure and biochar on the growth and yield of tomato.
Materials and Methods: A greenhouse experiment was conducted at the Federal College of Forestry Ibadan, using polyethylene bag with 5 kg soil collected at two (2) soils depths, 0-15 cm and 15-30 cm depth at the botanical garden, Federal College of Forestry Ibadan. The experiment was arranged in a completely randomized design (CRD) with four replicates. The treatments used were poultry manure (5t/ha), biochar (10t/ha), mixture of poultry manure and biochar (1:1) and control (no amendment).The tomato seeds (UC82B) were sourced from NIHORT, Ibadan and raised in a germination basket. Data were collected weekly on plant height, collar diameter and number of leaves, 50% days to flowering and yield of tomato plants from two weeks after transplanting (WAT). Data collected were analyzed statistically using ANOVA while means were separated using LSD (p<0.05) where applicable.
Results: In 0-15 cm soil, the growth variables (plant height, number of leaves and collar diameter) increased with various treatments used. The highest tomato height was observed with the application of biochar (10t/ha). All the treatments applied affected the number of tomato leaves at all weeks after transplanting (WAT) with poultry manure 5t/ha having the highest number of leaves at 7WAT, while collar diameter was significantly affected by various treatments from 2 to 5 WAT, with the mixture of P.M + BIO (1:1) recording the highest value and the control plot recorded the least values in all weeks. However, in 15-30 cm soil, there was significant difference in the number of leaves of tomato among all the amended soil from 5 to 7 WAT, the highest tomato leaves were obtained when the soil was amended with poultry manure (5t/ha) and can be compared with other treatments. Interaction of poultry manure and biochar(1:1) and poultry manure 5 t/ha resulted in highest height of tomato plant from 3-7 WAT as compared to the control that had the least value but were not significantly different from the sole application of biochar 10t/ha. Interaction of poultry manure + biochar (1:1) and poultry manure (5t/ha) gave the highest tomato flowering and fruits.
Conclusion: Based on this result, biochar and poultry manure when added to soil, boosted the mineralization of the soil after amendment.

Aim: Natural products play a pivotal role in innovative drug discovery by providing structural leads for the development of new therapeutic agents against various diseases. The present study aims to focus on the in silico assessment of the therapeutic potential of antidiabetic phytoconstituents which were identified and isolated from the extracts of Bauhinia rufescens Lam., a medicinal plant traditionally used for various pharmacotherapeutic purposes.
Methods: The physicochemical and pharmacokinetic parameters of the isolated thirty eight compounds were predicted using Swiss ADME web tool whereas OSIRIS Property Explorer was used for toxicity risk assessment and drug- likeliness. Twelve compounds were selected for docking on human α-glucosidase and α-amylase enzymes using Autodock 4.0 software.
Results and Discussion: Eriodictyol was found to have the highest potential as an inhibitor against α-amylase with binding energy of -9.92 kcal/mol. Rutin was the most potent against α-glucosidase with binding energy of-9.15 kcal/mol. A considerable number of hydrogen bonds and hydrophobic interactions were computed between the compounds and the enzymes thereby making them energetically favorable and suggesting inhibition of these two enzymes as a plausible molecular mechanism for their antidiabetic effect.
Conclusion: These two flavonoids could therefore be used as potential leads for structure- based design of new effective hypoglycemic agents.

AbstractThe development of advanced catalyst integration strategy is of great importance and promising for long‐term and stable gas catalysis in environmental processing. However, conventional catalyst fabrication techniques including spray method and spin coating cannot overcome the key problems of catalyst peeling off from substrate and related severe performance degradation. In this work, an in situ integration strategy of monolithic Au/TiO2 catalysts on Ti mesh for efficient and stable low‐temperature CO oxidation is reported. Plasma electrolytic oxidation technology can create a porous TiO2 seeding layer with strong substrate adherence. Subsequent hydrothermal reaction, ion exchange, and calcination processes can induce the in situ nucleation of sodium titanate nanosheets and their follow‐up conversion to TiO2 nanosheets with huge surface area. The oxygen defects generated in anatase TiO2 nanosheet supports can not only provide sufficient anchoring sites for the deposition and attachment of gold nanoparticles (Au NPs) during deposition–precipitation process, but also absorb and activate oxygen species. Meanwhile, the strong interactions between Au NPs and TiO2 support make the catalysts more chemically active. As a result, the Au/TiO2 monolithic catalysts can eliminate CO completely at low temperature and exhibit considerably high stability, suggesting their potential in practical applications.

Published: May 2020

AbstractThe iodine(III) reagents vinylbenziodoxolones (VBX) were employed to vinylate a series of aliphatic and aromatic thiols, providing E‐alkenyl sulfides with complete chemo‐ and regioselectivity, as well as excellent stereoselectivity. The methodology displays high functional group tolerance and proceeds under mild and transition metal‐free conditions without the need for excess substrate or reagents. Mercaptothiazoles could be vinylated under modified conditions, resulting in opposite stereoselectivity compared to previous reactions with vinyliodonium salts. Novel VBX reagents with substituted benziodoxolone cores were prepared, and improved reactivity was discovered with a dimethyl‐substituted core.

AbstractThe assembly of atomically precise metal nanoclusters offers exciting opportunities to gain fundamental insights into the hierarchical assembly of nanoparticles. However, it is still challenging to control the assembly of individual nanoclusters at a molecular or atomic level. Herein, we report the dimeric assembly of Au25(PET)18 (PET=2‐phenylethanethiol), where two Au25(PET)18 monomers are bridged together by two Ag atoms to form the Ag2Au50(PET)36 dimer. The Ag2Au50(PET)36 dimer is a unique mesomer, which has not been found in any other chiral metal nanoclusters. Furthermore, the Ag2Au50(PET)36 dimer is distinct from the Au25(PET)18 monomer in its optical, electronic, and catalytic properties. This study is expected to provide a feasible strategy to precisely modulate the assembly of metal nanoclusters with controllable structures and properties.
Fuzzy DNA Strand Displacement: A Strategy to Decrease the Complexity of DNA Network Design
Authors: Wang Zhiyu , Hu Yingxin , Pan Linqiang 
Published: May 2020

AbstractToehold‐mediated DNA strand displacement endows DNA nanostructures with dynamic response capability. However, the complexity of sequence design dramatically increases as the size of the DNA network increases. We attribute this problem to the mechanism of toehold‐mediated strand displacement, termed exact strand displacement (ESD), in which one input strand corresponds to one specific substrate. In this work, we propose an alternative to toehold‐mediated DNA strand displacement, termed fuzzy strand displacement (FSD), in which one‐to‐many and many‐to‐one relationships are established between the input strand and the substrate, to reduce the complexity. We have constructed four modules, termed converter, reporter, fuzzy detector, and fuzzy trigger, and demonstrated that a sequence pattern recognition network composed of these modules requires less complex sequence design than an equivalent network based on toehold‐mediated DNA strand displacement.

Published: May 2020

AbstractMost CdTe photoanodes and photocathodes show positive and negative photocurrent onset potentials for water oxidation and reduction, respectively, and are thus unable to drive photoelectrochemical (PEC) water splitting without external applied biases. Herein, the activity of a CdTe photoanode having an internal p‐n junction during PEC water oxidation was enhanced by applying a CdCl2 annealing treatment together with surface modifications. The resulting CdTe photoanode generated photocurrents of 1.8 and 5.4 mA cm−2 at 0.6 and 1.2 VRHE, respectively, with a photoanodic current onset potential of 0.22 VRHE under simulated sunlight (AM 1.5G). The CdCl2 annealing increased the grain sizes and lowered the density of grain boundaries, allowing more efficient charge separation. Consequently, a two‐electrode tandem PEC cell comprising a CdTe‐based photoanode and photocathode split water without any external bias at a solar‐to‐hydrogen conversion efficiency of 0.51 % at the beginning of the reaction.

Published: May 2020

AbstractRhenium tricarbonyl complexes have been recently investigated as novel anticancer agents. However, little is understood about their mechanisms of action, as well as the means by which cancer cells respond to chronic exposure to these compounds. To gain a deeper mechanistic insight into these rhenium anticancer agents, we developed and characterized an ovarian cancer cell line that is resistant to a previously studied compound [Re(CO)3(dmphen)(ptolICN)]+, where dmphen=2,9‐dimethyl‐1,10‐phenanthroline and ptolICN=para‐tolyl isonitrile, called TRIP. This TRIP‐resistant ovarian cancer cell line, A2780TR, was found to be 9 times less sensitive to TRIP compared to the wild‐type A2780 ovarian cancer cell line. Furthermore, the cytotoxicities of established drugs and other rhenium anticancer agents in the TRIP‐resistant cell line were determined. Notably, the drug taxol was found to exhibit a 184‐fold decrease in activity in the A2780TR cell line, suggesting that mechanisms of resistance towards TRIP and this drug are similar. Accordingly, expression levels of the ATP‐binding cassette transporter P‐glycoprotein, an efflux transporter known to detoxify taxol, were found to be elevated in the A2780TR cell line. Additionally, a gene expression analysis using the National Cancer Institute 60 cell line panel identified the MT1E gene to be overexpressed in cells that are less sensitive to TRIP. Because this gene encodes for metallothioneins, this result suggests that detoxification by this class of proteins is another mechanism for resistance to TRIP. The importance of this gene in the A2780TR cell line was assessed, confirming that its expression is elevated in this cell line as well. As the first study to investigate and identify the cancer cell resistance pathways in response to a rhenium complex, this report highlights important similarities and differences in the resistance responses of ovarian cancer cells to TRIP and conventional drugs.

Published: May 2020

AbstractThe arterial supply of the cat jejunum was studied by gross dissection and polyurethane corrosion cast. The results showed that the jejunal arteries, which originate from the cranial mesenteric artery, varied from 5 to 15 in number. Their number was independent of the length of the cranial mesenteric artery as well as of the length of the jejunum. These arteries divided into branches giving rise to a series of orders of division from a minimum of 1 to a maximum of 7. The last orders of division terminated in a series of anastomosing arcades which resulted in a marginal artery coursing only a few millimeters from the mesenteric margin of the jejunum. This artery gave rise to straight arteries (vasa recta), whose mean number was 450 ± 60. According to their length, the vasa recta can be differentiated into short (vasa brevia) and long (vasa longa) branches. The vasa brevia ended branching into the mesenteric side of the jejunum whereas the vasa longa coursed beneath the serosa on the lateral jejunal surfaces, and reached the antimesenteric border. During their course, the vasa recta ramified and anastomosed with each other. Numerous antimesenteric anastomoses between opposing vasa longa were also observed. Based on the literature consulted, due to the large number of vasa recta (approximately one vessel per 2.9 mm of jejunal length) and the rich anastomotic network, the cat jejunum might have a better intramural distribution of blood flow and would seem less predisposed to ischemic phenomena than that of other mammals.

Published: May 2020

AbstractIn order to solve the problem that the low‐order torsional model of the integrated helicopter/turboshaft engine system varies significantly under variable rotor speed, research on adaptive torsional vibration suppression methods is conducted. Meanwhile, two adaptive torsional vibration suppression methods, respectively based on fast Fourier transform (FFT) and the least mean square (LMS), are proposed to suppress the low‐order torsional vibration mixing in power turbine speed. Moreover, these two torsional vibration suppression methods are compared in real‐time performance, suppression effect and robustness of performance. The simulation results show that when and only when the designed frequency of the notch filter is away from the low‐order torsional model, the suppression effect of adaptive torsional vibration filter based on FFT is better than that of constant‐coefficient notch filter, but the real‐time performance is worse. On the contrary, no matter how the low‐order torsional model varies, the adaptive filters based on LMS can suppress the low‐order torsion vibration by more than 82.0% and have more superior real‐time and robustness performance, which can overcome torsional vibration instability of turboshaft engine control system under variable rotor speed effectively with more remarkable adaptive ability.

Published: May 2020

AbstractBewehrungsstäbe aus carbonfaserverstärktem Kunststoff (CFK) haben bei bestimmten Anwendungen Vorteile gegenüber den derzeit eingesetzten Stahlbewehrungsstäben. Insbesondere die hohe Zugfestigkeit von CFK‐Bewehrung verspricht bei einem Einsatz als Betonbewehrung potenzielle Materialersparnisse und der Werkstoff weist vergleichsweise gute Eigenschaften in Bezug auf die Korrosion auf. Die Autoren versuchen, CFK‐Bewehrung zur Herstellung von filigranen Betonbauteilen zu verwenden und somit den ökologischen Fußabdruck zu senken. Für die Berechnung des Tragverhaltens solcher Bauteile ist fundamentales Wissen über das Verbundverhalten zwischen Bewehrung und Beton notwendig. Die Autoren untersuchen aktuell das Verbundverhalten von CFK‐Stäben mit unterschiedlichen Betonzusammensetzungen. In einem ersten Schritt wurde das Verbundverhalten von subtraktiv bearbeiteten CFK‐Stäben mit ultrahochfestem Beton (engl. Ultra‐High Performance Concrete – UHPC) adressiert. Eingangs wird im vorliegenden Beitrag eine Übersicht über das Verbundverhalten von Faserverstärkten Kunststoff (FVK)‐Stabbewehrungen in Beton gegeben. Anschließend werden zwei Serien von Ausziehversuchen von helikal eingefrästen CFK‐Stäben in UHPC präsentiert. Die verwendeten Materialien, die Versuchsaufbauten, die Versuchsdurchführung und die Ergebnisse werden vorgestellt und im Detail analysiert.

AbstractIn Anlehnung an das bei dem Bau der Argentobelbrücke angewandte Bogenklappverfahren wurde an der TU Wien ein Bauverfahren mit senkrechter Herstellung der Brückenträger entwickelt, um bei geeigneten Projekten Ressourcen, Kosten und Zeit zu sparen. Der Mechanismus zur Rotation der Brückenträger von der senkrechten Startposition in die horizontale Endposition erfordert den Einsatz von Druckstreben. Diese bilden in endgültiger Lage einen integralen Teil des Tragsystems und bewirken eine wesentliche Verkürzung der Spannweiten. Zur Reduktion des Aufwands für die Herstellung der Gelenkskonstruktionen entschied das Projektteam, dass die während des Klappvorgangs bewegten Teile (Brückenträger und Druckstreben) möglichst leicht sein müssen. Deshalb wurden in einem Forschungsprojekt an der TU Wien dünnwandige vorgespannte Fertigteilträger entwickelt. Im Zuge des Baus der Fürstenfelder Schnellstraße im Südosten Österreichs konnte das Brückenklappverfahren für die Brücken über den Lahnbach und die Lafnitz erstmals eingesetzt werden. Die in diesem Beitrag beschriebene Erstanwendung dieses neuen Bauverfahrens bei der Brücke über den Lahnbach konnte dank der guten Zusammenarbeit der Projektbeteiligten erfolgreich abgeschlossen werden. Mit der Erstanwendung konnte auch gezeigt werden, dass die mit dem Brückenklappverfahren errichtete Spannbetonbrücke mit 2,0 m hohen Brückenträgern beträchtliche Einsparungen an Ressourcen und Kosten im Vergleich zur ursprünglich geplanten Stahl‐Beton‐Verbundbrücke mit 4,2 m hohen Brückenträgern ermöglichte.

AbstractBackgroundSurgeons need guidance regarding appropriate personal protective equipment (PPE) during the COVID-19 pandemic based on scientific evidence rather than availability. The aim of this article is to inform surgeons of appropriate PPE requirements, and to discuss usage, availability, rationing and future solutions.MethodsA systematic review was undertaken in accordance with PRISMA guidelines using MEDLINE, Embase and WHO COVID-19 databases. Newspaper and internet article sources were identified using Nexis. The search was complemented by bibliographic secondary linkage. The findings were analysed alongside guidelines from the WHO, Public Health England, the Royal College of Surgeons and specialty associations.ResultsOf a total 1329 articles identified, 95 studies met the inclusion criteria. Recommendations made by the WHO regarding the use of PPE in the COVID-19 pandemic have evolved alongside emerging evidence. Medical resources including PPE have been rapidly overwhelmed. There has been a global effort to overcome this by combining the most effective use of existing PPE with innovative strategies to produce more. Practical advice on all aspects of PPE is detailed in this systematic review.ConclusionAlthough there is a need to balance limited supplies with staff and patient safety, this should not leave surgeons treating patients with inadequate PPE.
