The Shortest Distance from the Skin to Pancreas and the Lower Sternum Angle can Influence Short-Term Surgical Outcomes of Laparoscopy-Assisted Distal Gastrectomy for Gastric Cancer

Background The surgery of laparoscopic distal gastrectomy + D2 lymph node dissection (LADG) is widely used in patients with gastric cancer, the purpose of the study is to explore the effect of abdominal shape on short-term surgical outcomes.Methods This was a retrospective study which included 316 patients undergoing LADG from January 2013 to June 2019 at a single clinical center. The abdominal parameters including the shortest distance of the pancreas from the anterior abdominal skin (PAAD), the lower sternum angle (LSA), the thickness of subcutaneous fat at the navel level (SFT), the anteroposterior diameters (APD) and left-right diameters(LRD) at the navel level, the distance from xiphoid process to the navel (XND), and the distance from xiphoid process to the pubis (XBD) were calculated by preoperative abdominal computed tomography (CT) image. The parameters and short-term surgical outcomes were analyzed.Results In males, the number of retrieved lymph nodes was significantly higher in patients with BMI <25kg/m2 (p=0.023) and APD <176.2mm (p=0.004). The time of operation was significantly shorter in male patients with BMI <25kg/m2(p=0.001), PAAD <64.6mm(p=0.000), SFT <14.9mm(p=0.017), APD <176.2mm(p=0.002) and LRD <290.0mm(p=0.036), and in female patients with XBD >370.0mm(p=0.042). The estimated blood loss was significantly lower in male patients with LSA <83.8° (p=0.009), PAAD <64.6mm(p=0.001), SFT <14.9mm(p=0.001), APD <176.2mm(p=0.009) and LRD <290.0mm(p=0.011). The complications were fewer in male patients with PAAD <64.6mm(p=0.045) and APD <176.2mm(p=0.011), and in female patients with LRD <288.5mm(p=0.047). Conclusion Various abdominal shapes can influence the difficulty of LADG. Lower LSA and PAAD can reduce the difficulty of LADG in male patients.
Preparation and Characterization of Alcogels Based on (Poly Ethylene Glycol Methyl Ether Methacrylate-Acrylic Acid) Copolymers

Alcohol absorbents based on poly ethylene glycol methyl ether methacrylate (PEGMEMA) macromer and acrylic acid (AA) were prepared via solution polymerization using trimethyl propane triacrylate (TMPTA) as crosslinker. Swelling capacity of gels was measured in water, ethanol and methanol. Alcohol absorbency was increased with increasing AA content, which can be related to the ability of an AA segment in formation of H-bonding and dissociation of COOH groups to produce of mobile ions. The alcogels absorb ethanol and methanol up to 14.8 and 17.4 g/g, respectively. TG analysis shows that increasing AA content caused an increase of thermal stability of alcogels.
The threshold dynamics of a discrete-time echinococcosis transmission model

In this paper, based on the transmission mechanism of echinococcosis in China, we propose a discrete-time dynamical model for the transmission of echinococcosis. The research results indicate that transmission dynamics of this discrete-time model are determined by basic reproduction number \begin{document}$ R_{0} $\end{document} . It is shown that when \begin{document}$ R_{0}\leq1 $\end{document} then the disease-free equilibrium is globally asymptotically stable and when \begin{document}$ R_{0}>1 $\end{document} then the model is permanent while the disease-free equilibrium is unstable. Finally, on the basis of the theoretical results established in this paper, we come up with some specific measures to control the transmission of echinococcosis.
A Novel Heterojunction BiOBr/Bismuth Oxyhydrate Photocatalyst with Highly Enhanced Visible Light Photocatalytic Properties

In this study, a facile and effective method to modify the photocatalytic performance of a bismuth oxybromide (BiOBr) semiconductor through the fabrication of a heterojunction with a hydrated bismuth oxide (BHO) is reported. The new yBiOBr-(1 – y)BHO heterojunction, synthesized by a simple hydrothermal method, exhibits a high photocatalytic activity under visible light irradiation for the photodegradation of typical organic pollutants in water, such as Rhodamine B (RhB) and acetophenone (AP). Both the individual BiOBr and BHO components show very low photocatalytic efficiency. Furthermore, the unique photocatalytic performance of the new hybrid material was demonstrated through the uphill photocatalytic reaction that involves the oxidation of potassium iodide (KI) to triiodide. The remarkable photocatalytic activity of the coupled system is directly related to the effectual charge carrier separation due to the formation of the heterostructure. 0.9BiOBr-0.1BHO shows a higher photocatalytic activity as comp.

Hybrid CNN-LSTM Model with GloVe Word Vector for Sentiment Analysis on Football Specific Tweets

The football fans feelings get unfold during the different phases of the football match, they express their opinions, views, thoughts, judgments of the match, attitude towards player, and emotions, stance on social media like Twitter. The change in fans opinions are reflected in a series of tweets written by fans. This research work focuses on identifying and analyzing sentiment in tweets expressed by football fans on Twitter. To perform sentiment analysis, we analyzed different word embedding techniques to represent word vectors that capture semantic and syntactic information. In this paper, we use a global vector(GloVe) word embedding technique which produces word vector with substructure and leverages statistics. In addition to GloVe, we also construct a sentiment lexicon as additional information. The word vector produced by GloVe and sentiment lexicon is the inputs for the proposed hybrid CNN-LSTM deep learning model. The proposed CNN-LSTM model blend benefits of CNN and LSTM, CNN used to excerpt features from word embedding that reflect short-term sentiment dependency while LSTM used to build long-term sentiment relationships among words. This the paper also used machine learning algorithms such as Random Forest, Support Vector Machine, Multinomial Nave Bayes, KNearest Neighbours(KNN) and XG Boost for sentiment analysis and sentiment classification. We evaluated the performance of proposed hybrid CNN-LSTM with GloVe word embedding approach with 2018 FIFA world cup tweets dataset, our experiment results show 85.46% and 92.56% validation and testing accuracy respectively. Further, our experiment results also demonstrate that the Random Forest algorithm perform consistent and robust performance compared to other machine learning classifiers, it perceive fan’s sentiment during football events.

A New Harmonic Analysis Reporting Technique to Improve Power Quality in Distribution System Network Applications

Harmonic analysis and reporting in distribution power system to improve power quality has been experiencing exponential growth in future grid power quality issues. A large number of power quality metering instruments, penetration of many non-linear loads and integration of distributed generation (DG) provide a large amount of data for both current and voltage harmonics which are convenient for investigating power quality problems. The main objective of this paper is to develop a new method of reporting broad range of harmonic order performance data measure at different individual location of load without omitting significant information. This topology will help in reporting large amount of individual harmonic order detail to a simple harmonic spectrum. Lastly, a MATLAB/Simulink model for the IEEE 9-bus distribution system is investigated to implement the proposed methodology using raw data for analysis and reporting.
Nuclear Imaging: Physician Confusion Over True Quantification and Isotope Redistribution

Clinicians are beginning to understand the importance of quantification for use in medicine, particularly nuclear medicine. With the recent introduction of mandates by CMS, ASNC, and the SNMMI for quantification, it is not surprising that professional papers are beginning to be published on the topic. One recent publication paper by Zhao et al. demonstrates the misunderstanding that is plaguing the field of modern nuclear medicine. The second publication by Dorbala et al. discusses a major flaw in the current understanding of redistribution measurements of isotopes such as Sestamibi and Tetrofsomin
The Effects of Bicycle Versus Arm Ergometer Exercise Training on Physical Functions and Lipid Profile in Patients Who Underwent Coronary Artery Bypass Surgery: A Randomized Trial

Part of this study was presented as an oral presentation at the 9th International Sports Physiotherapists Congress in Ankara. ABS TRACT Objektive: The aim of this study was to compare the effects on physical functions (PF) and lipid profile (LP) of bicycle and arm ergometer exercises among the patients, who underwent coronary artery bypass graft (CABG) surgery. Material and Methods: The study involved 50 patients, who underwent CABG surgery. The patients were randomly divided into 2 groups. After the exclusion of 11 cases, evaluation was performed of 23 patients in the bicycle ergometer group (BEG) and 16 patients in the arm ergometer group (AEG). All the subjects participated in a cardiac rehabilitation program con-sisting of exercise training with bicycle or arm ergometer exercise for a total of 30 sessions as 5 sessions per week during 6 weeks. Before and after the exercise training, the 6-minute walking test distance (6MWTD), body composition evaluation, and blood lipid levels were recorded. Results: Before and after the exercise training, statistically significant positive changes were observed in the BEG including increased 6MWD, and LP parameters containing decreased percentage of body fat, LDL, trigliserid level, and total cholesterol. Statistically significant changes were found in the AEG including increased 6MWTD and LP parameters containing HDL, decreased body fat percentage, BMI, LDL, triglis- erids, and total cholesterol. Comparing the values between the groups, it was found that there was a statistically significant increase in the 6MWD in the BEG when compared to the AEG. Conclusions: In conclusion, bicycle and arm ergometer exercises had a positive effect on PF and LP after CABG surgery. For improving the functional capacity, the bicycle ergometer training was seen to be more advantageous.
Contribution à l'élaboration d'une nouvelle formulation de l'ibuprofène pour la compression directe

Ibuprofen is one of the most used anti-inflammatory with or without drug prescription, the aim cf this study is ta prepare tablets with a high concentration of ibuprofen at the following concentrations 200, 400 and 600 mg using direct tableting without going through the granulating method; direct tableting method is simple and less expensive, it is also considered suitable for hygroscopic and thermally labile actives. The purpose of this study is ta meet the following three points: Prepare a pharmaceutical form as economically as possible, Prepare a pharmaceutical form as small as possible, A quick and effective bioavailability. The flow, the compressibility, the solubility and the dissolution of ibuprofen are very poor, which limits the making of the pharmaceutical form by direct tableting. The addition of excipients (binders, solubilizers, disintegrants .) intended for direct tableting can rectify those problems. Avicel® PH 102, which is the excipient of choice, was the object cf our study. Different percentage will be used in each formula; the idea is to see what proportion of the binder can always obtain a compliant tablets. Only a high concentration can ensure such compliance; ibuprofen is at 50% in the formula, which is not the ultimate aim cf this work. The use cf Avicel® PH102, HPMC and excipient X together, give very favorable and promising results, the pharmacotechnical characters (content uniformity, hardness, friability, and disintegration time) are satisfying according to the European Pharmacopoeia; ibuprofen is at 90% in the formula, which is the purpose of this work. Adopting this new formula can bring some benefits: Reducing manufacturing time by 50% Decreased direct casts up ta 7% Decreased indirect costs up ta 35% lncrease the batch size up ta 11%.
DrPin: A dynamic binary instumentator for multiple processor architectures

Modern applications rely heavily on dynamically loaded shared libraries, making static analysis tools used to debug and understand applications no longer sufﬁcient. As a consequence, dynamic analysis tools are being adopted and integrated into the development and study of modern applications. Building tools that manipulate and instrument binary code at runtime is difﬁcult and error-prone. Because of that, Dynamic Binary Instrumentation (DBI) frameworks have become increasingly popular. Those frameworks provide means of building dynamic binary analysis tools with low effort. Among them, Pin 2 has been by far the most popular and easy to use one. However, since the release of the Linux Kernel 4 series, it became unsupported, and Pin 3 broke backward compatibility. In this work we focus on studying the challenges faced when building a new DBI (DrPin) that seeks to be compatible with Pin 2 API, without the restrictions of Pin 3, that also runs multiple architectures (x86-64, x86, Arm, Aarch64), and on modern Linux systems.
Metallic nanoparticles and ions accelerate the uptake of extracellular antibiotic resistance genes through transformation

Background: Antibiotic resistance genes (ARGs), heavy metal ions and nanoparticles (NPs) are emerging and ubiquitous contaminants in the environment. However, little is known about whether heavy metal-based NPs or ions could facilitate the dissemination of ARGs through natural transformation. This study evaluated the contributions of heavy metal-based NPs (Ag NPs, CuO NPs and ZnO NPs) and their ion forms (Ag + , Cu 2+ and Zn 2+ ) to the transformation of extracellular ARGs in Acinetobacter baylyi ADP1. Results: We found that these commonly-used NPs and ions from environmentally relevant concentrations can significantly promote the natural transformation frequency of ARGs by a factor of 11.0-folds, which is comparable to the effects of antibiotics. The enhanced transformation by Ag NPs, CuO NPs, Ag + and Cu 2+ was primarily associated with reactive oxygen species (ROS) over-production and cell membrane damage, which was also evident from up-regulations of both transcription and translation of ROS and outer membrane-related genes. Additionally, transmission electron microscope imaging revealed the roughened cell membrane after Ag NPs, CuO NPs, Ag + and Cu 2+ exposure. ZnO NPs and Zn 2+ might increase the natural transformation rate by stimulating the stress response and ATP synthesis. All tested NPs and ions resulted in up-regulating the competence and SOS response-associated genes. Conclusions: Our results demonstrate that Ag, CuO and ZnO-based NPs/ions from environmental concentrations could promote the natural transformation of plasmid-encoded ARGs into naturally competent A. baylyi . Our findings provide insights into the contributions of heavy metals and NPs to the spread of antibiotic resistance.
Clinical scoring for the failure of non-invasive ventilation in acute respiratory failure patients in the Emergency Department.

Background Non-invasive mechanical ventilation (NIV) has become an alternative to an invasive artificial airway for the management of acute respiratory failure (ARF). NIV failure causes delayed intubation, which eventually has been associated with increased morbidity and mortality. This study aimed to develop the clinical scoring system of NIV failure in ARF patients. Methods This study was a diagnostic, retrospectively cross-sectional, and exploratory model at the Emergency Medicine Department in Ramathibodi Hospital between February 2017 and December 2017. We included all of the acute respiratory failure patients aged >18 years and received non-invasive ventilation (NIV). Clinical factors associated with NIV failure were recorded. The predictive model and prediction score for NIV failure were developed by multivariable logistic regression analysis. Result A total of 329 acute respiratory failure patients have received NIV success (N = 237) and failure (N = 92). This study showed that NIV failure was associated with heart rate > 110 bpm, systolic BP < 110 mmHg, SpO2 < 90%, arterial pH < 7.30 and serum lactate. The clinical scores were classified into three groups: low, moderate, and high. Conclusion We suggested that the novel clinical scoring of the NIV failure in this study may use as a good predictor for NIV failure in the emergency room.
Optical properties and fluorescence quenching of biologically active ethyl 4-(4-N,N-dimethylamino phenyl)-2-methyl-5-oxo-4,5-dihydro-1H-indeno[1,2-b]pyridine-3-carboxylate (DDPC) dye as a probe to determine CMC of surfactants

4-(4-N,N-Dimethylamino phenyl)-2-methyl-5-oxo-4,5-dihydro-1H-indeno[1,2-b]pyridine-3-carboxylate (DDPC) was prepared via the multi-component reaction of indane-1,3-dione with 4-(dimethylamino)benzaldehyde, ethyl acetoacetate and ammonium acetate. Data obtained from FT-IR, 1H-NMR, 13C-NMR, EI-MS and elemental analysis were consistent with the chemical structure of the newly prepared DDPC. Electronic absorption and emission spectra of DDPC were measured in different solvents. The DDPC dye exhibits a red shift in its emission spectrum as the solvent polarity increases, indicating a large change in the dipole moment upon excitation due to intramolecular charge transfer within the excited DDPC molecules. Excited state intermolecular hydrogen bonding has an effect upon the energy of the emission spectrum and the fluorescence quantum yield of the DDPC molecules. The DDPC dye undergoes solubilization into different micelles and can be used as a probe to determine the critical micelle concentration (CMC) of SDS and CTAB. The DDPC dye can also be used to probe of the polarity and hydrogen bonding properties of its local micro-environment. The antibacterial activity of DDPC was tested in vitro for the first time by using a disk diffusion assay against two Gram-positive and two Gram-negative bacteria, and the minimum inhibitory concentration (MIC) was also determined with reference to the standard drug tetracycline.
Etude sur les additifs solvants introduits pour augmenter le rendement de cellules solaires organiques : leurs sélections et leurs effets

Polymeric bulk heterojunction (BHJ) organic solar cells (OSCs) have attracted significant interest as a low cost and renewable technology to harvest solar energy. However, their generally low efficiencies are a barrier for their movement into commercial application. Controlling the BHJ morphology is a key step in the pursuit of higher OSC efficiencies. Processing additives have emerged as effective components for optimizing the BHJ morphology. This thesis provides a comprehensive study on the introduction of additives in the formulation of semiconductors. The semiconductor system studied is based on poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PC61 BM). First, a method was developed to guide the selection of additives from a large range of solvents. This method employs the Hansen solubility parameters of the semiconductors and was successfully applied to the P3HT/PC61 BMsystem. It resulted in the identification of three new efficient additives. Next, the mechanistic role of additives in influencing the BHJ morphology is investigated by performing structural, electrical and optical characterizations. Also, the effect of additives on OSC performance was found to depend on the type of the OSC architecture. Such differences were correlated to the variations in charge carrier mobilities caused by the additive. Furthermore, photo-stability tests, performed on different types of OSCs, showed that processing additives can improve the photo-stability. The origin of such improvement is investigated. Finally, the scope of this study is extended to two other donor semiconducting polymers.
Crystal structure of Calcium Formate

The strucutre of orthorhombic calcium formate was analysed by the method of Fourier series. Oscillation-rotation photographs were taken with Cu-Kα radiation around the three principal axes and the following unit cell dimensions and space group were obtained, which confirmed the results of the previous work (Nitta, 1927) ; a=10.163A. , b=13.381A. , c=6.27. 1A. (at 18°C) ; space group, D152h—Pcab; Z=8. All the atoms are on the general positions 8 (c) :± (xyz; 1/2+x, 1/2-y, z; x, 1/2+y, 1/2-z; 1/2-x, y, 1/2+z) . with the parameters shown in Table I.The analysis was effectuated by the method of two-dimensional and three-dimensional Patterson syntheses, the latter being evaluated along lines through several points corresponding to peaks in P (xy) . The structure obtained may be explained as consisting of chains of the type shown in the figure parallel to the c-axis, which are laterally bound through formate ions to form a compact spatial network (Fig.2) . Three types of interionic linkage are found (Fig.3), two of which were already found in sodium formate, analysed by Zachariasen. A remarkable feature is the asymmetrical type of coordination (type II), which might be characteristic to ions of lower symmetry such as this. The calcium ions are surrounded by eight oxygen atoms as shown in Fig.4, one of them being somewhat more apart (Table III) . Pauling's rule concerning the stability of ionic crystals are shown to be strictly hold in its extended form. The shape of the formate, groups were found to be :C-C=1.25, 1.25, 1.25, 1.24 (±0.03A.) ; OCO=125°, 124° (±4°) . These results suggest an almost complete resonance between the two forms proposed by Pauling.
