Authors: Carroll Kenneth A. , Kuntz Charles A. , Heller Jane , Peters Andrew , Rotne Randi , Dunn Andrew
Published: May 2020

OBJECTIVE

To investigate putative associations between oral melanoma size and variables of histologic grade such as mitotic index, nuclear atypia, junctional activity, ulceration, lymphatic invasion, and degree of pigmentation.

SAMPLE

59 samples of oral melanomas from dogs sourced from 6 diagnostic laboratories within Australia.

PROCEDURES

The size of each melanoma was microscopically measured, and each sample was evaluated for variables of histologic grade including mitotic index, nuclear atypia, junctional activity, ulceration, lymphatic invasion, and degree of pigmentation by a veterinary pathologist. The association between tumor size and histologic outcomes was then statistically evaluated.

RESULTS

A significant relationship was identified between the size of oral melanomas and a single variable of histologic grade, lymphatic invasion, with larger tumors more likely to show lymphatic invasion. Further analysis revealed 2 applicable size thresholds for different clinical scenarios. Results indicated lymphatic invasion can confidently be ruled out for tumors < 6.5 mm in diameter (100% sensitivity) and ruled in for tumors ≥ 24.5 mm in diameter (100% specificity).

CONCLUSIONS AND CLINICAL RELEVANCE

An association was found for oral melanomas of dogs between tumor size and lymphatic invasion.
Use of radiographic measurements to diagnose stage B2 preclinical myxomatous mitral valve disease in dogs
Authors: Stepien Rebecca L. , Rak Mariola B. , Blume Lauren M.
Published: May 2020

OBJECTIVE

To investigate the usefulness of radiographic measures of the left atrium and ventricle as surrogates for echocardiographic criteria in identifying dogs with stage B2 preclinical myxomatous mitral valve disease (MMVD).

ANIMALS

56 client-owned dogs with preclinical mitral regurgitation attributed to MMVD examined between April 19, 2016, and November 22, 2017.

PROCEDURES

Medical records were retrospectively searched, and data collected included age, body weight, heart murmur grade, and echocardiographic and radiographic measurements. Dogs were grouped according to whether they did (case dogs) or did not (control dogs) meet echocardiographic criteria used to identify dogs with stage B2 MMVD. Measurements for lateral thoracic radiographic variables normalized to vertebral body units (VBUs) were obtained, and results were analyzed to identify variables that could best discriminate between case and control dogs.

RESULTS

Three radiographic variables of left atrial size (vertebral left atrial size [VLAS], left atrial width, and the combined variable of VLAS + left atrial width) most accurately distinguished control dogs from case dogs, and the VLAS was the simplest and fastest to perform in a clinical setting. The optimal cutoff for VLAS was 2.5 VBUs (sensitivity, 70%; specificity, 84%; and likelihood ratio, 4.38), with VLAS ≥ 2.5 VBUs for case dogs. The maximum specificity cutoff for VLAS was 3.0 VBUs (sensitivity, 40%; specificity, 96%; and likelihood ratio, 10.0), with VLAS ≥ 3.0 VBUs for case dogs.

CONCLUSIONS AND CLINICAL RELEVANCE

Results indicated that when echocardiography is unavailable, radiographic VLAS ≥ 3 VBUs could be used with minimal risk of false-positive diagnosis of stage B2 MMVD in dogs.

The factors influencing the backing process of the book block spine are deter-mined and their priorities are established. The method of backing the spine of book blocks in the production of publications by the method of perfect binding is proposed. This method involves gluing the backingcaptal braid to the spine of the block with a preapplied adhesive layer. The positive influence of the presence of the adhesive layer of a certain thickness on the physical and mechanical characteristics of the backing material is determined. It is established that the thickness of the blocks, the type of paper, from which the publications are made, and the direction of the cutting of the backing mate-rial is influenced by the process of backing the spine. With the growth of the tension deformation of backing materials from 1.2% (for kraft paper) to 3.8% (for the backing braid), the stability of the spine zone of the block increases to damage in the process of multiple flippers. The investigated materials in the longitudinal direction are more durable than in the transverse in 2-2.5 times, so the backed blocks can withstand 4,800 to 15,000 flippers when using kraft paper and backing braid, respectively. With the help of optical microscopy, changes in the structure of the backingcaptal braid after the multiple flippers of the book block have been investigated. It is shown that the strength of the binding of a book block depends on the choice of the method of backing. In the process of optimizing the parameters of backing the block root, various variants of linear models were tested, which are described by the functions of the dependences of the breaking forces in the longitudinal or transverse directions Z on the thickness of the block Tb. The allowable elongation of the edging material for its longitudinal and transverse cuttingV is also taken into account. The obtained models allow for the particular type of paper to pick up the necessary backing materials, which will provide a sufficient strength to the perfect binding book blocks.

An interface that emerges from the relationship between Educommunication and Environmental Education, this concept will be exposed based on a bibliographic systematization, when it becomes possible to find the contemporary intersections that arise from the use of audiovisual technology as mediation in the teaching-learning process. Such analysis will be done taking into consideration the documentary 1,2,3 Playing –Reinventing School Spaces, produced by the city of Joinville, Santa Catarina, which brings an audiovisual material made by the students. Using a quanti-qualitative approach, emerges the pedagogical power of Socioenvironmental Education, which ends up bringing to the scene language and content that project another way of thinking the school. Finally, there is a reflection on how, based on particularities, it is possible to create educational policies that contemplate the audiovisual tool in early childhood education.
The didactic planning in the performance of pedagogues from the Service of Coexistence and Strengthening of Bonds in João Pessoa-PB
Authors: DIAS Luciana Silva , SEVERO José Leonardo Rolim de Lima
Published: May 2020

This article aims to discuss the meanings attributed by the pedagogues from the Service of Coexistence and Strengthening of Bonds, in the city of João Pessoa, Paraíba, about the didactic planning process that they develop in their socio-educational routine. The article is based on research that had a qualitative approach inspired by the focus on symbolic interactionism. For data collection, structured questionnaires were answered by 15 educators who are part of the service in João Pessoa. To analyze the data, content analysis was used. It was possible to realize that planning is part of the daily life of the professionals surveyed, with an emphasis on the technical-operational framework of the Service of Coexistence and Strengthening of Bonds and on interests highlighted by the students. The political dimension related to the social meaning of the action they plan is not very evident, which can lead to the loss of transformative power of Social Education practices in the Service of Coexistence and Strengthening of Bonds.

Art as an object of expert activity
Authors: Markina Nina Aleksandrovna
Published: May 2020

This article puts to the forefront the problem of unbiased and objective assessment of artworks by the expert community, analysis of the priority criteria of such assessment and chains of perception of professional works of art by the representatives of expert groups. The author leans on the fact that the expert community in the field of art may be defined as a category of professionals possessing extensive knowledge and erudition in the sphere of culture and art, attracted for conducting expertise on the contemporary artworks and cultural heritage of the past centuries. It is underlinesd that the problematic aspect of expert communities in the field of arts is the substantial disaccord of emotional and visual-imager perception different for assessing the works from the perspective of aesthetics, and demand to act by the rules, patterns and methods. The author also points out that the expert community in their practical activity should be guided by realization of the essential rules, laws, formulas, as well as see the zones for their implementation.

This article carries out a socio-philosophical analysis of interaction between the phenomena of politics and law. The goal of this work consist in the review of the existing correlations between politics and law. The subject of research is the correlations between politics and law. For achieving the set goal, the history of the question is considered. The author presents integral and differential characteristics of the two indicated categories. The definition to the concept of “political-legal institution” is provided alongside the modern classification by various grounds. The novelty is substantiated by the fact that there are virtually no philosophical writings on the analysis of correlations between politics and law. The formulated conclusions have theoretical and practical importance: reflect the characteristics of politics and law; confirm the justification of their institutional realization; underline the duality of nature of the political-legal institutions; propose classification of political-legal institutions for clearer understanding of the vectors of institutional transformations and emergence of neoforms in the context of current global development.

Evaluation of Traditional Ayurvedic Preparation for Prevention and Management of the Novel Coronavirus (SARS-CoV-2) Using Molecular Docking Approach
Authors: Maurya Dharmendra Kumar , Sharma Deepak
Published: May 2020

Since the emergence of novel Coronavirus (SARS-CoV-2) infection in Wuhan, China in December 2019, it has now spread to over 205 countries. The ever-growing list of globally spread corona virus-19 disease (COVID19) patients has demonstrated the high transmission rate among human population. Although 12 new drugs are being tried for management of COVID19, currently there are no FDA approved drugs or vaccines to prevent and treat the infection of the SARS-CoV-2. Considering the current state of affairs, there is an urgent unmet medical need to identify novel and effective approaches for prevention and treatment of COVID19 by re-evaluating the knowledge of traditional medicines and repurposing of drugs. Here, we used molecular docking approach to explore the beneficial roles of an array of phytochemicals and active pharmacological agents present in the Indian herbs (Tulsi, Haldi, Giloy, Black pepper, Ginger, Clove, Cardamom, lemon, and Ashwagandha) which are widely used in the preparation of Ayurvedic medicines in the form of Kadha to control various respiratory disorders such as cough, cold and flu. The evaluation was made based on the docking scores calculated by AutoDock Vina. Our study has identified an array of phytochemicals present in these herbs which have significant docking scores and potential to inhibit different stages of SARS-CoV-2 infection as well as other Coronavirus target proteins. Molecular docking also indicated that, the phytochemicals present in these herbs possess significant anti-inflammatory property. Overall our study provides scientific justification in terms of binding of active ingredients present in different plants used in Kadha preparation with viral proteins and target proteins for prevention and treatment of the COVID19. This preparation can boost individual’s immunity and inhibit the viral severity by interfering at different stages of virus multiplication in the infected person.
A Predictive Model of the Temperature-Dependent Inactivation of Coronaviruses
Authors: Yap Te Faye , Liu Zhen , Shveda Rachel A. , Preston Daniel
Published: May 2020

The COVID-19 pandemic has stressed healthcare systems and supply lines, forcing medical doctors to risk infection by decontaminating and reusing medical personal protective equipment intended only for a single use. The uncertain future of the pandemic is compounded by limited data on the ability of the responsible virus, SARS-CoV-2, to survive across various climates, preventing epidemiologists from accurately modeling its spread. However, a detailed thermodynamic analysis of experimental data on the inactivation of SARS-CoV-2 and related coronaviruses can enable a fundamental understanding of their thermal degradation that will help mitigate the COVID-19 pandemic and future outbreaks. This paper introduces a thermodynamic model that synthesizes existing data into an analytical framework built on first principles, including the Arrhenius equation and the rate law, to accurately predict the temperature-dependent inactivation of coronaviruses. The model provides much-needed thermal sterilization guidelines for personal protective equipment, including masks, and will also allow epidemiologists to incorporate the lifetime of SARS-CoV-2 as a continuous function of environmental temperature into models forecasting the spread of coronaviruses across different climates and seasons.

This paper presents TorchANI, a PyTorch based software for training/inferenceof ANI (ANAKIN-ME) deep learning models to obtain potential energy surfaces andother physical properties of molecular systems. ANI is an accurate neural networkpotential originally implemented using C++/CUDA in a program called NeuroChem.Compared with NeuroChem, TorchANI has a design emphasis on being light weight,user friendly, cross platform, and easy to read and modify for fast prototyping, whileallowing acceptable sacrifice on running performance. Because the computation ofatomic environmental vectors (AEVs) and atomic neural networks are all implementedusing PyTorch operators, TorchANI is able to use PyTorch’s autograd engine to automatically compute analytical forces and Hessian matrices, as well as do force trainingwithout additional codes required.
Deep Learning for Multi-Scale Molecular Modeling
Authors: Zhang Jun , Lei Yaokun , Yang Yi Isaac , Gao Yi Qin
Published: May 2020

Molecular simulations are widely applied in the study of chemical and bio-physical systems. However, the

accessible timescales of atomistic simulations are limited, and extracting equilibrium properties of systems

containing rare events remains challenging. Two distinct strategies are usually adopted in this regard: either

sticking to the atomistic level and performing enhanced sampling, or trading details for speed by leveraging

coarse-grained models. Although both strategies are promising, either of them, if adopted individually,

exhibits severe limitations. In this paper we propose a machine-learning approach to ally both strategies so

that simulations on different scales can benefit mutually from their cross-talks: Accurate coarse-grained (CG)

models can be inferred from the fine-grained (FG) simulations through deep generative learning; In turn, FG

simulations can be boosted by the guidance of CG models via deep reinforcement learning. Our method

defines a variational and adaptive training objective which allows end-to-end training of parametric

molecular models using deep neural networks. Through multiple experiments, we show that our method is

efficient and flexible, and performs well on challenging chemical and bio-molecular systems.

Water-pipe smokers are at risk of exposure to many toxic chemicals that are not filtered by water, as well as risk of infectious diseases when the mouth piece of the water-pipe is shared. This study was carried out to investigate the effect of water pipe on the oral health. Materials and Methods: Sixty persons were included in this study aged between 22 and 23 years. Forty persons were coffee shop workers for at least five years, half of them were water-pipe smokers (active smokers) and the other weren’t smokers (passive smoker), the last group was the control group which includes twenty non-smoker students matching the study group in the age, gender and geographical location. They had been diagnosed for plaque index of Silness and Leo in1964, calculus index according to calculus component of the Periodontal Disease Index, (PDI) of Ramfjord 1959 and gingival index of Löe and Sillness 1963 as well as loss of attachment according to criteria of WHO in1997. The values of the present study were subjected to statistical analysis by Statistical Package for Social Sciences version 20 to specify the statistical differences between the three groups. The Kruskal-wallis test was used to determine the statistical significance of difference between the three groups. Mann-Whitney test was used to assess the statistical significance of difference between each 2 groups. Results: The mean rank values of dental plaque were recorded to be the highest among the coffee shop workers who were active water-pipe smokers group followed by the workers who were passive water-pipe smokers then control with statistically highly significant difference. Similar results were obtained concerning gingival and calculus indices with statistically highly significant difference. There is no significant difference concerning the attachment loss attachment loss among water-pipe smokers and the control group. Conclusions: this study concluded that water-pipe smoking is negatively associated with the oral cleanness and gingival health.

Background: The microorganisms can impend the life of health care professional and particularly the dental practitioners. They can be transmitted by different ways like airborne and droplet transmission. The current study was carried out to identify whether the arch wires that received from the manufactures are free from microbial contamination and to determine the bacterial species attached to the arch wires. Materials and Methods: This study involved eighty samples, consisted of two types of arch wires (nitinol and stainless-steel) from four companies (3M, G&H, Jiscop, OrthoTechnology). These wires inserted in a plane tube that contains 10 -ml of (Tris [tris(hydroxymethyl)aminomethane] and EDTA (ethylenediaminetetraacetic acid) tris-EDTA and brain heart infusion (BHI) broth. A 0.1 ml was withdrawn from the tube and spread on agar plates. The control groups consist of 16 plane tube (8 tubes with tris-EDTA and other 8 tubes with (BHI). Results: Microbial sampling yielded growth from 5 of the 80 arch wires. The predominant bacteria that isolated were Bacillus spp. No growth was recovered from 75 of the samples and from controls. The bacteria were isolated by BHI reagent and no growth was observed by tris-EDTA reagent with statistically significant difference (P<0.05). The Bacillus spp. found only in the G&H and Jiscop companies, however, no statistically significant difference was found among them (P>0.05). With regard to the presence and distribution of bacteria according to the types of wires, the present results clarified that cases of contamination with Bacillus spp. were found in the nitinol arch wires with statistically significant difference (P<0.05). Conclusions: The results of the current study revealed low count of bacterial contamination in the two types of companies (G&H and Jiscop). Not all materials that received from the manufactures are free from contamination and an effective sterilization regimen is needed to avoid cross-contamination.

Background: Dental caries is a localized, progressive destructive, largely irreversible microbial based disease of multifactorial nature; these factors include (host, microbes and food) they influence differently on the initiation and progression of dental caries. The aims of the study: was to evaluate the effect of smoking on salivary flow rate, secretory immunoglobulin (SIgA) level and viable count of mutans streptococci (M.S) bacteria in oral cavity and their relation to dental caries experience. Material and method: The samples were collected from 80 male students ranging in ages from 18-22 years old. Where they divided in to two groups, 40 non-smokers (control group) and 40 smokers (study group). Unstimulated salivary samples were collected. Salivary flow rate was estimated and viable count (CFU/ml) of mutans streptococci was determined. The diagnosis and recording of dental caries were done according to WHO, 1987 criteria and the level of SIgA was determined by ELISA. Result: the result revealed that the salivary flow rate and SIgA level were lower in smoker group than non-smoker, while the means value of dental caries experience Decay, Missing and Filling tooth (DMFT) and (CFU/ml)of M.S were higher in oral cavity of smoker group than non-smoker group. Conclusion: the smoking has negative effect on salivary flow rate, SIgA and increase the viable bacterial count of M.S and dental caries in smoker patients
Perineural Invasion in Oral Squamous Cell Carcinoma in Relation to Tumor Depth

Background: The American Joint committee on Cancer in their 8th edition staging manual regarded perineural invasion as one of the most important prognostic factors for Lip and Oral Cavity Squamous Cell Carcinoma, it also incorporated tumor depth of invasion in defining tumor size category in the new staging system. This study was conducted to evaluate the frequency of perineural invasion in oral squamous cell carcinoma and the effect of approaching tumor depth in this process. Materials and Methods: fifty-four formalin fixed paraffin embedded tissue blocks of radical resections of Oral Squamous Cell Carcinoma were cut and stained with Hematoxylin and Eosin stain, then evaluated for perineural invasion, with estimation of tumor depth of invasion for each case. Results: Perineural invasion was found in twenty-two cases of the study sample. The diameter of the largest nerve bundle that showed perineural invasion was found to have a positive significant correlation with tumor depth of invasion (p=0.025). Perineural invasion status in terms of (present, absent) showed a significant difference with patients’ age (p=0.037), also showed a significant association with tumor site (p=0.004), however, this association was non-significant in regard to tumor grade and stage (p=0.848, p=0.520) respectively. Conclusion: The attacking potential of preceding tumor depth and those cancers affecting young individuals may be reflected by the presence of neural infiltration by tumor cells. Tongue resected tumors should be carefully inspected for this deceptive biological process.

Background: Dental caries is one of the most significant problems in world health care. Restoring carious primary teeth is one of the major treatment goals for Children, and the light activated resin restoration materials like composite, resin-modified glass ionomer and polyacid-modified which was introduced in dentistry in 1970, widely used in clinical dentistry but its application increased dramatically in recent years because of its biocompatibility, color matching, good adhesive properties of its resemblance in physical and mechanical aspects to tooth. The aim of this study: To evaluate the microleakage of Polyacid-Modified Composite resin Compared to Flowable Hybrid Composite and Resin-Modified Glass ionomer cement. Materials and methods: Thirty extracted primary molar teeth and thirty extracted permenant premolar teeth were used in this study 20 for each material, then standardized Class V cavities of teeth was prepared in the buccal and lingual surfaces. Using Polyacid-modified composite Resin (Compomer), flowable composite resin and Resin-modified glass Ionomer RMGI. The samples will be divided into three groups according to type of restorative material used and light cured with a light cure device (Ivoclar Vivadent Bluephace), after complete curing the sample will examined by Scanning electron microscope (SEM) and then measure the microleakage. Results: The RMGI shows the statistically significantly lowest mean value of microleakage, followed by Compomer shows statistically significantly lower mean value. Flowable Composite shows the statistically significantly highest mean microleakage. There is no statistically significant difference in microleakage values between the permanent and primary teeth. Conclusion: The Resin-modified glass Ionomer is better in term of microleakage than Polyacid-modified composite Resin and Flowable Composite.
