Abstract

OBJECTIVE
To examine potential relationships between ECG characteristics and echocardiographic measures of cardiac structure in chimpanzees (Pan troglodytes).

ANIMALS
341 chimpanzees (175 males and 166 females) from 5 sanctuaries and 2 zoological collections.

PROCEDURES
Chimpanzees were anesthetized for routine health examinations between May 2011 and July 2017 as part of the International Primate Heart Project and, during the same anesthetic events, underwent 12-lead ECG and transthoracic echocardiographic assessments. Relationships between results for ECG and those for echocardiographic measures of atrial areas, left ventricular internal diameter in diastole (LVIDd), and mean left ventricular wall thicknesses (MLVWT) were assessed with correlational analysis, then multiple linear regression analyses were used to create hierarchical models to predict cardiac structure from ECG findings.

RESULTS
Findings indicated correlations (r = −0.231 to 0.310) between results for ECG variables and echocardiographic measures. The duration and amplitude of P waves in lead II had the strongest correlations with atrial areas. The Sokolow-Lyon criteria, QRS-complex duration, and R-wave amplitude in leads V6 and II had the strongest correlations with MLVWT, whereas the Sokolow-Lyon criteria, QRS-complex duration, and S-wave amplitude in leads V2 and V1 had the strongest correlations with LVIDd. However, the ECG predictive models that were generated only accounted for 17%, 7%, 11%, and 8% of the variance in the right atrial end-systolic area, left atrial end-systolic area, MLVWT, and LVIDd, respectively.

CONCLUSIONS AND CLINICAL RELEVANCE
Results indicated that relationships existed between ECG findings and cardiac morphology in the chimpanzees of the present study; however, further research is required to examine whether the predictive models generated can be modified to improve their clinical utility.

Abstract

OBJECTIVE
To evaluate the time and number of laser beam passes required to make full-thickness skin incisions and extent of laser-induced tissue artifacts following use of a CO2 laser at various settings.

SAMPLE
24 skin specimens from six 5-month-old porcine carcasses.

PROCEDURES
4 full-thickness skin specimens were harvested from the flank regions of each carcass within 30 minutes after euthanasia and randomly assigned to 4 treatment groups. Three 5-cm-long incisions were made in each specimen with a CO2 laser (beam diameter, 0.4 mm) set to deliver a continuous wave of energy alone (groups 1 and 2) or in superpulse mode (groups 3 and 4) at 10 (groups 1 and 3) or 20 (groups 2 and 4) W of power. The time and number of passes required to achieve a full-thickness incision were recorded, and extent of laser-induced tissue artifact (as determined by histologic evaluation) was compared among the 4 groups.

RESULTS
Mean time required to make a full-thickness skin incision for groups 2 and 4 (power, 20 W) was significantly less than that for groups 1 and 3 (power, 10 W). Mean number of passes was lowest for group 2 (continuous wave at 20 W). Extent of laser-induced tissue artifact was greatest for group 4 (superpulse mode at 20 W).

CONCLUSIONS AND CLINICAL RELEVANCE
Results provided preliminary information regarding use of CO2 lasers to make skin incisions in veterinary patients. In vivo studies are necessary to evaluate the effect of various CO2 laser settings on tissue healing and patient outcome.

Elucidar a influência da dieta rica em FODMAPs nos sintomas de pacientes com Síndrome do Intestino Irritável. Trata-se de um estudo de caso múltiplos, realizado com pacientes que possuíam síndrome do intestino irritável, conduzido em seis indivíduos do sexo feminino. Foram analisados parâmetros de avaliação clínica e dietética, incluindo recordatório 24 horas e questionário de frequência alimentar adjunto de dados antropométricos para resultar no estado nutricional das participantes. Além disso, foi questionado os principais sintomas e causas da exacerbação da sintomatologia. Os dados foram quantificados em gráficos e tabelas do Microsoft Excel 2016, para análise descritiva. Em relação ao estado nutricional, as pacientes apresentaram resultados diversos, não havendo prevalência. Na análise alimentar foi possível avaliar que a maioria das pacientes não estava com a ingesta calórica, glicídica, protéica e lipídica adequada, de acordo com os parâmetros comparados. Observou-se também a presença de alimentos ricos em FODMAPs que foram excluídos ou reduzidos da dieta habitual, devido a contribuição na exacerbação dos sintomas.

Published: May 2020

Relevance. Ectopic pregnancy is an urgent condition which may lead to intraabdominal hemorrhage and woman death. In recent years, the frequency of this pathology is significantly increasing. However, morphological changes in the fallopian tubes in patients with this disease remain understudied.
Aim. To study morphological changes in the fallopian tubes in patients with ectopic pregnancy with various variants of the clinical course.
Materials and methods. The morphological study included 130 patients who had laparoscopic surgery for ectopic pregnancy. Comprehensive morphological study of the fallopian tubes removed during surgery was conducted.
Results and discussion. The article presents the morphological changes in the fallopian tubes in patients with ectopic pregnancy. Implantation of a fertilized egg in the fallopian tube led to significant changes in its macro- and microstructure, which were due to invasion of the chorionic villi and involved all layers of the tube wall, differing only in depth and prevalence. The most pronounced morphological changes in various segments of the tube were revealed in the endosalpinx.
Conclusion. The combination of morphological changes in different layers of the tube is related to a chronic non-specific productive endomyosalpingitis with luminal deformation, which was one of the main causes of this disease development.

Published: May 2020

Background
Both long- and short-term epidemiology are fundamental to disease control and require accurate bacterial typing. Genomic data resulting from implementation of whole genome sequencing in many public health laboratories can potentially provide highly sensitive and accurate descriptions of strain relatedness. Previous typing efforts using these data have mainly focussed on outbreak detection.

Aim
We aimed to develop multilevel genome typing (MGT), using consecutive multilocus sequence typing (MLST) schemes of increasing sizes, stepping up from seven-gene MLST to core genome MLST, to allow examination of genetic relatedness at multiple resolution levels.

Methods
The system was applied to Salmonella
enterica serovar Typhimurium. The MLST scheme used at each step (MGT level), defined a given MGT-level specific sequence type (ST). The list of STs generated from all of these increasing MGT levels, was named a genome type (GT). Using MGT, we typed 9,096 previously characterised isolates with publicly available data.

Results
Our approach could identify previously described S. Typhimurium populations, such as the DT104 multidrug resistance lineage (GT 19-2-11) and two invasive lineages of African isolates (GT 313-2-3 and 313-2-752). Further, we showed that MGT-derived clusters can accurately distinguish five outbreaks from each other and five background isolates.

Conclusion
MGT provides a universal and stable nomenclature at multiple resolutions for S. Typhimurium strains and could be implemented as an internationally standardised strain identification system. While established so far only for S. Typhimurium, the results here suggest that MGT could form the basis for typing systems in other similar microorganisms.

Building World-Class University in Pakistan: Opportunities and Constraints
Authors: Authors Contributing , Khawar Ayesha , Arif Seema 
Published: May 2020

The article explores the issues of academic excellence in higher education to pursue a position in world-class universities. Two universities in Pakistan have been chosen for the site of this qualitative study, one which has achieved the status, and the other still aspiring. The triangulation has been reached by a document analysis of the quality reports submitted by the two universities, semi-structured interviews with the senior and middle management of the universities, deans, and director for Quality Enhancement Cells, and head of the departments of the selected universities. The primary data obtained have been compared and contrasted with the quality characteristics marked by standards for academic excellence. Research findings inform us that unawareness of the international quality standards, and its potential benefits, the disinterest of university leadership are the main problems, due to which Pakistani universities are lagging behind. The study proposes if proper understanding and meaningfulness is created through quality professionalism, it would become much easier to pursue quality assurance process to meet international standards. The findings of the study will be a unique contribution to the body of literature creating a point of interest to policymakers and quality assurance practitioners of the developing countries who are concerned about the academic excellence of Higher Education Institutions (HEIs) to accentuate in the significant areas which make any university, a world-class university.

Published: May 2020

A fishing operation is a dangerous and high risk activity. Stability of the vessel plays an important role in performing safely and successfully fishing operations. A brand new 30 GT purse seiner, production of a traditional shipyard in Batang Regency, experienced 15o heel after its launch. This condition potentially affects the stability of the vessel. The purpose of the study is to analyze the vessel stability and improve existing stability by adding outriggers. Research was conducted in two phases, data collection in the research site and stability analysed using a naval architecture software. The vessel stability was analyzed in six loading scenarios following the fishing operation process, subsequently the stability was compared against IMO standard. Results show that with the existing design, the vessel does not meet IMO criteria for the most applied scenarios. Next step, outriggers were added in both sides of the vessel model, as an effort to improve its stability. Accordingly, it is revealed that outriggers addition is scientifically proven to improve the stability of the studied vessel. As this research merely focused on the stability improvement, further analysis regarding maneuverability is required given a purse seiner operates encircled fishing gear.

Considerations for comparing video-game AI agents with humans
Authors: Madan Christopher R 
Published: May 2020

Video games are sometimes used as environments to evaluate AI agents' ability to develop and execute complex action sequences to maximize a defined reward. However, humans cannot match the fine precision of timed actions of AI agents--in games such as StarCraft, build orders take the place of chess opening gambits. However, unlike strategy games, such as chess and go, video games also rely heavily on sensorimotor precision. If the `finding' was merely that AI agents have superhuman reaction times and precision, none would be surprised. The goal is rather to look at adaptive reasoning and strategies produced by AI agents that may replicate human approaches or even result in strategies not previously produced by humans.Here I will provide: (1) an overview of observations where AI agents are perhaps not being fairly evaluated relative to humans, (2) a potential approach for making this comparison more appropriate, and (3) highlight some important recent advances in video-game play provided by AI agents.

Published: May 2020

Objectives.This study is devoted to developing new-generation nickel (Ni) catalysts for the purification of a nitrogen–hydrogen mixture from carbon oxides, which should encompass the best qualities of the NIAP-07-series solid catalysts.Methods. This study used derivatographic and radiographic methods; temperature-programmed recovery, decomposition, and joint temperature-programmed decomposition and recovery; and low-temperature nitrogen adsorption (specific surface determination). The mechanical strength of catalysts was determined using an MP-2C device by crushing granules with an applied load on the end face. The chemical composition and catalytic activity were determined by the methods of TU 2178-003-00209510 Technical Conditions.Results.Many studies regarding Ni–aluminum (Al)–calcium (Ca) methanation catalyst at all stages of its preparation have been conducted. It is demonstrated that Ni hydrocarboxyaluminate, a precursor of the active component of the catalyst, is formed when Ni hydroxocarbonate is mixed with active alumina in the presence of an aqueous solution of ammonia, and its chemical formula is established. Moreover, it was found that the mechanical strength of the catalyst is determined by the amount of industrial Ca aluminate added to the Ni–Al composition. The compositions of catalysts with different contents of the active component have been optimized.Conclusions.The developed catalyst has a low activation temperature and high catalytic activity, thermal stability, and mechanical strength and is resistant to organic and alkaline carbon dioxide absorbers. The catalyst can be produced in the form of a ring, cylindrical tablets, and extrudates of various geometric sizes. The methanation unit at Stavrolen (Budennovsk, Stavropol krai, Russia) has begun commercially operating the catalyst.

Published: May 2020

Objectives. The addition of high-density carbon materials to jet fuels can lead to a significant increase in the volumetric energy of the fuel combustion. The purpose of the current study was to thermodynamically analyze the possibility of obtaining model hydrocarbon fuels from toluene and T-1 using stacked-cup multiwall carbon nanotubes (MWCNTs). Methods. Bomb combustion calorimetry was used to define the combustion energy of the MWCNTs in the crystalline state. The temperature dependence of the MWCNTs’ heat capacity in the range 5–370 K and the fusion parameters were estimated using low-temperature adiabatic calorimetry. The physical density of MWCNTs was measured using the pycnometric method. The sedimentation stability of the mixtures of MWCNTs with liquids was determined using centrifugation at 7000 g. The calculations were carried out in MS Excel. Results. The energy and enthalpy of combustion of a technical sample of MWCNTs in the crystalline state were determined. Based on the smoothed heat capacity values, the standard thermodynamic functions (enthalpy, entropy, and Gibbs reduced energy) of MWCNTs in the crystalline state were obtained in a temperature range of 0–2000 K. The extrapolation of the MWCNTs’ heat capacity was carried out at a temperature of up to 2000 K using the heat capacity of crystalline graphite. It has been established that mixtures of MWCNTs with liquids containing more than 33 mass % of MWCNTs are stable during centrifugal sedimentation at 7000 g. For the toluene–MWCNTs and fuel T-1–MWCNTs model systems, the specific and volumetric combustion energies, the adiabatic combustion temperatures, and the conditional final maximum speed of the model rockets with fuel of various compositions were also calculated. Conclusions. The thermodynamic analysis showed that the addition of MWCNTs can significantly increase the volumetric energy intensity of traditional jet fuels, which can in turn improve the operational characteristics of drones and rockets.

Published: May 2020

Objectives. This study evaluates the effect of the modification process on the group composition of bitumen and bitumen binders containing rubber powder and hybrid modifier that is based on styrene–butadiene thermoplastic elastomer and rubber crumb. The aim of the study was to determine the presence or absence of functional groups that reflect the direction of physicochemical processes during the preparation of a hybrid modifier in rotary dispersers and during the modification of bitumen binders. Methods. Rubber powder and hybrid modifier were obtained by high-temperature shear grinding using a rotary disperser. Bitumen and modified bitumen binders were investigated via Fouriertransform infrared spectroscopy. Using the method of spectral subtraction, it was determined that during the process of manufacturing modified bitumen binders, structural changes occur in both bitumen and modifiers. During this study, the extraction of modifiers (rubber powder and hybrid modifier) in toluene was performed. Results. The quantitative analysis of changes in the group composition of modifiers before and after the modification procedure was carried out. The active polymer and structural indices were determined. The general trend of the change in the active polymer and structural indices was noted for the initial spectra of the rubber powder and hybrid modifier, and their spectra were obtained after the procedure of subtraction from the spectra of bitumen binders. Conclusions. The interdiffusion of aromatic compounds between the bitumen component and modifier particles was confirmed. On the basis of the results of the extraction of modifiers in toluene, and by taking into account the infrared spectroscopy data, it was determined that during the production of hybrid modifier during the simultaneous grinding of rubber crumb and styrene– butadiene thermoplastic elastomer, there was a chemical interaction between them.
