Esophageal Cancer and Treatment Modalities
Authors: Vidyadhar Takalkar Unmesh
Published: December 2020

Esophageal cancer is eighth most common cancer worldwide with high biological aggressiveness and poor prognosis. Switching of predominant type from squamous cell carcinoma to adenocarcinoma in Western population, ethnic discrepancies and increased occurrences have identified it as major public health problem. Though monotherapy includes – surgery, radiotherapy and chemotherapy, optimal therapy for esophageal cancer is still debated. Treatment requires a multi-modal approach which includes chemotherapy, radiation therapy with or without surgical follow-up for most patients and chemoradiation for those with inoperable disease; endoscopic therapies, including radiofrequency ablation, endoscopic mucosal resection and endoscopic sub mucosal dissection for Barrett’s esophagus/ early carcinoma patients and minimally invasive surgical approaches are standards for esophagectomy. Advancement in diagnostic techniques and the multi-modal treatment approach has led to an improvement in the overall survival of esophageal cancer patients.

Authors:   COVID-19 National Incident Room Surveillance Team
Published: December 2020

Nationally, COVID-19 notifications remained at low levels this fortnight. The daily average number of cases for this reporting period was nine, which was similar to last fortnight’s average. There were 123 cases of COVID-19 and no deaths this fortnight, bringing the cumulative case count to 27,892 and 907 deaths. Hospitalisations for COVID-19 dropped further in the past two fortnights: there were just two cases admitted to FluCAN participating hospitals and there were no admissions to ICU in SPRINT-SARI sites during this four-week period. New South Wales reported the highest proportion of cases this fortnight (46%; 56/123), all of which were overseas acquired. Locally-acquired cases accounted for 15% (19/123) of all cases reported this fortnight all of which were attributed to a cluster of cases in South Australia. At the end of this reporting period, it had been 24 days since there was a locally-acquired case of unknown source. Testing rates increased to 12.0 tests per 1,000 population per week during this reporting period, driven by a significant increasing in testing in South Australia. The overall positivity rate for the reporting period was 0.03%, will all jurisdictions reporting a positivity rate ≤ 0.10%.

Published: December 2020

One of the main problems in the theory of homeostasis and the theory of functional systems of the human body is the problem of choosing standards. It turned out that the statistics poorly diagnose the norm (standard) of function of the human body. The aim of the study was to assess the possibility of using a new quantitative criteria - the area of the pseudoattractors (Eskov's quasiattractors) as standard (physiological norm) parameters. Methods. In a group of 15 women (mean age = 28 ± 2,3 years, who have been living in the North of the Russian Federation in Ugra for more than 15 years), cardiointerval samples were recorded (300 cardiointervals per sample) 225 times for each test subject. As a result, we calculated 15 matrices of pairwise comparisons of samples. A total of 225 matrices for all 15 subjects and 225 areas of S pseudoattractors for each subject were created. Area S was found from the formula S = Δx1 х Δх2, where Ax1 is the range for cardio intervals, and Δx2 is the range for Δx1. Results. All 225 matrices for 15 subjects showed showed a substantial variability in samples of cardiointervals. However, S areas showed statistical stability for each of 15 subjects. Conclusions: further application of statistics in the calculation of cardio intervals is problematic due to the statistical instability of the samples, therefore we propose to use areas of pseudoattractors to assess the physiological norm.

Published: December 2020

The incidence of head injuries is increasing particularly in cities. The aim was to study cellular immune response during the first 24 hours following head injuries among men aged 41-60 years and older. Methods: Altogether, 90 men aged 41-60 years were enrolled within 24 hours after head injury. Phenotypes of lymphocytes CD3+, CD4+, CD5+, CD71+, CD8+, CD16+, CD25+, CD95+, HLA-DR+, CD10+ were studied. Results. Proportion of mature T-lymphocytes increased in parallel with the increase of severity of trauma (11.1 % in mild traumas vs. 37.5 % in severe cases). In cases with average degree of trauma low concentrations of activators were detected (CD25+ = 0,23 ± 0,03 • 109 c/l; CD71+ = 0,24 ± 0,01 • 109 c/l and HLA-DR+ = 0,26 ± 0,02 • 109 c/l) combined with T-cells deficiency. Concentrations of CD8+ and CD95+ increase with the severity of the trauma: (0,64 ± 0,04) - (0,76 ± 0,01) • 109 c/l; (0,51 ± 0,02) - (0,56 ± 0,01) • 109 c/l, respectively. Conclusions: An increase in helper-suppressor ratio (k > 2) due to T-helpers as a compensation for low concentrations of CD5+, CD3+, CD25+, CD71+ and HLA-DR+ seems to be associated with favorable prognosis. In severe head injuries a decrease in helpersuppressor ratio (k < 2) accompanied by CD5+, CD3+ deficiency can be explained by an increase in CD8+. An increase in cytotoxic activity of lymphocytes during the first 24 hours after trauma may be associated with unfavorable prognosis.

Purpose. Improving of a forecast monitoring system of the fire hazard territory.

Methods. To obtain a qualitatively new result the approach of Big Data including static (relatively slowly changing in time) data, ground information from meteorological stations and satellite data over a long period of time is applied.

Findings. A forecast monitoring system of factors characterizing the fire hazard of the territory is developed. The system includes remote access service (providing data to users), database of forecast monitoring statistics, data processing and analysis subsystems. The structure of the system is relatively universal with the ability to complete and change both the functions themselves and the tasks to be solved. This allows considering the system as a preliminary stage of introducing modern approaches to fire hazard forecasting on the territory in the Republic of Belarus. The creation of the system is the beginning of a new forecast stage in the development of mechanisms of response to natural fires in the Republic of Belarus.

Application field of research. The results of a forecast monitoring system of factors characterizing the fire hazard of the territory may be used in daily activities of the departments of the Ministry of Emergency Situations of the Republic of Belarus and the Ministry of Forestry of the Republic of Belarus to reduce damage due to natural fires.

Published: December 2020

Purpose. The development of a semi-empirical model of calculating the effect of water curtains on the propagation of hazardous chemical vapors with wind flow from a local source of release (spillage).

Methods. Laboratory studies of the absorption of gaseous impurities by moving water drops. Field tests to determine the parameters of the actual contamination zone in the conditions of ammonia and chlorine spills with free spread of impurities and in the conditions of setting up water curtains. Fuller's method. Galerkin's method. Method of straight lines. Mathematical modeling. Three-dimensional solution of the turbulent diffusion equation. Inter- and extrapolation estimates. Semi-empirical calculations using the results of laboratory research, field tests and mathematical modeling.

Findings. The absorption capacity and transmittance index of water curtains created with the use of a hose spray are calculated in case of the propagation of ammonia and chlorine with a wind flow from the source of emission (spillage). A formula is proposed for calculating the numerical density of the impurity taking into account the transmittance index and fractional impurities not absorbed by the water curtain. The boundaries of the actual contamination zone were determined with the free spread of ammonia and chlorine from the surface of the strait and under the conditions of setting up water curtains. A method is proposed for calculating the depth of the actual contamination zone using the curtain transmittance. A semi-empirical model has been developed for calculating the effect of water curtains on the propagation of hazardous chemical vapors with a wind flow from a local source of release (spillage).

Application field of research. Prediction of the parameters of the actual contamination zone during the release (spillage) of a hazardous chemical during the rescue operations.

Published: December 2020

Purpose: Breast cancer is one of the most common cancers in women worldwide. Educational and awareness programs impact early practices of breast self-examination, resulting in the early detection of cancer and thereby decreasing mortality. The study aimed to assess the levels of knowledge and awareness of breast cancer and breast self-examination among medical and nursing students in Oman and to compare their knowledge, attitudes, and skills after a training program.Methods: This quasi-experimental study was carried out for female 90 medical and 80 nursing students in Oman in November 2019. A pre-test questionnaire was given before the training program and a post-test questionnaire was administered after the training program. Students’ knowledge, attitude, and skills regarding breast cancer and breast self-examination were compared. Scores for skills of practicing breast self-examination were compared between lecture and activity group and lecture-only group.Results: Pre-test and post-test data were collected from 170 female students. Significant improvements were observed in the post-test scores for students’ knowledge, attitude, and skills after the intervention (P<0.001). The mean scores for skills of practicing breast self-examination after the lecture and the activity were higher than those obtained after the lecture only (P=0.014 for medical students and P=0.016 for nursing students).Conclusion: An educational training program on breast cancer and breast examination with an emphasis on skills can motivate participants to perform breast self-examination regularly, and may therefore help students to train other women to perform breast self-examination for the early detection of breast cancer.

Authors: KORKUT Bora
Published: December 2020

Objective: This in vitro study was aimed to assess the effect of different surface sealants on discoloration of a nonofilled resin-based composite quantitatively, using a colorimeter.Methods: 40 specimens were prepared using nanofilled resin composite, Filtek Universal Restorative (A2 shade, 3M, USA). Sprecimens were polymerized from both sides, polished using polishing discs (SofLex, 3M, USA) and divided by test groups (n = 10 for each), regarding the sealant used; Permaseal (Ultradent Products, USA), Biscover LV (Bisco, USA), Optiglaze Clear (GC Corp., Japan) and control group. Samples were discolored for 144 hours in coffee solution, and color measurements were performed using colorimeter (ShadeStar, Dentsply Sirona, USA). Nominal color codes of specimens regarding Vita Classical Shade Guide, were converted to corresponding numerical values. Level of color change after sealant application (∆Vita1) and after discoloration (∆Vita2) were calculated. Shapiro Wilk and Kruskal Wallis tests were used forstatistical analyses.Results: Color changes in Permaseal, Optiglaze and control groups were significant (p < 0.001) compared to Biscover, for ∆Vita1 scores. Remarkable level of darkening was observed for all groups, for ∆Vita2 scores.

Authors: Romadhina Anggun Putri
Published: December 2020

This study considers agreeing and obtaining evidence about the Difference between Tax Accounting Choices, debt policy and Characteristics of Ownership of Aggressive Taxes. This research was conducted at manufacturing companies published on the Indonesia Stock Exchange (IDX) in 2014-2018. This type of research is quantitative research that is associative in nature. This research was conducted on 136 manufacturing companies listed on the Indonesia Stock Exchange (IDX) using purposive sampling technique in determining research samples. Then obtained as many as 15 (fiveteen) manufacturing companies used as research samples. With observations for 5 (five) years, so the total observations in this study were 75 (seventy-five) audited financial statement data. The analysis technique used is descriptive statistical tests, classical assumptions test, and hypothesis testing. The results of this study indicate that the partial variable tax accounting choices do not affect the tax aggressiveness, this shows that the method of depreciation of the straight line or straight line does not affect the tax aggressiveness decision making. Debt policy against tax aggressiveness, this refers to the fact that questioning the company using funds from the company will reduce the amount of money that will incur a small interest fee that will occur in an aggressive tax action. Ownership characteristics do not affect the tax aggressiveness, this shows that the company owned by family or non-family does not affect the decision in tax aggressiveness. And simultaneously the tax accounting choice variable, debt policy and ownership characteristics affect the tax aggressiveness.

Published: December 2020

Diagnosing Alzheimer’s disease (AD) in the preclinical stage offers opportunities for early intervention; however, there is currently a lack of convenient biomarkers to facilitate the diagnosis. Using radiomics analysis, we aimed to determine whether the features extracted from multiparametric magnetic resonance imaging (MRI) can be used as potential biomarkers. This study was part of the Sino Longitudinal Study on Cognitive Decline project (NCT03370744), a prospective cohort study. All participants were cognitively healthy at baseline. Cohort 1 (n = 183) was divided into individuals with preclinical AD (n = 78) and controls (n = 105) using amyloid-positron emission tomography, and this cohort was used as the training dataset (80%) and validation dataset (the remaining 20%); cohort 2 (n = 51) was selected retrospectively and divided into “converters” and “nonconverters” according to individuals’ future cognitive status, and this cohort was used as a separate test dataset; cohort three included 37 converters (13 from the Alzheimer’s Disease Neuroimaging Initiative) and was used as another test set for independent longitudinal research. We extracted radiomics features from multiparametric MRI scans from each participant, using t-tests, autocorrelation tests, and three independent selection algorithms. We then established two classification models (support vector machine [SVM] and random forest [RF]) to verify the efficiency of the retained features. Five-fold cross-validation and 100 repetitions were carried out for the above process. Furthermore, the acquired stable high-frequency features were tested in cohort three by paired two-sample t-tests and survival analyses to identify whether their levels changed with cognitive decline and impact conversion time. The SVM and RF models both showed excellent classification efficiency, with an average accuracy of 89.7–95.9% and 87.1–90.8% in the validation set and 81.9–89.1% and 83.2–83.7% in the test set, respectively. Three stable high-frequency features were identified, all based on the structural MRI modality: the large zone high-gray-level emphasis feature of the right posterior cingulate gyrus, the variance feature of the left superior parietal gyrus, and the coarseness feature of the left posterior cingulate gyrus; their levels were correlated with amyloid-β deposition and predicted future cognitive decline (areas under the curve 0.649–0.761). In addition, levels of the variance feature at baseline decreased with cognitive decline and could affect the conversion time (p < 0.05). In conclusion, this exploratory study shows that the radiomics features of multiparametric MRI scans could represent potential biomarkers of preclinical AD.
First-Principles Atomistic Thermodynamics and Configurational Entropy
Authors: Sutton Christopher , Levchenko Sergey V.
Published: December 2020

In most applications, functional materials operate at finite temperatures and are in contact with a reservoir of atoms or molecules (gas, liquid, or solid). In order to understand the properties of materials at realistic conditions, statistical effects associated with configurational sampling and particle exchange at finite temperatures must consequently be taken into account. In this contribution, we discuss the main concepts behind equilibrium statistical mechanics. We demonstrate how these concepts can be used to predict the behavior of materials at realistic temperatures and pressures within the framework of atomistic thermodynamics. We also introduce and discuss methods for calculating phase diagrams of bulk materials and surfaces as well as point defect concentrations. In particular, we describe approaches for calculating the configurational density of states, which requires the evaluation of the energies of a large number of configurations. The cluster expansion method is therefore also discussed as a numerically efficient approach for evaluating these energies.
Leaching Process of Weathered Crust Elution-Deposited Rare Earth Ore With Formate Salts
Authors: Chen Zhuo , Zhang Zhenyue , Chi Ruan
Published: December 2020

To strengthen the rare earth leaching process and weaken the hydration of clay minerals for preventing landslides, it is of great importance to adopt a green and sustainable leaching agent in the industry. In this work, the leaching process of weathered crust elution-deposited rare earth ores with formate salts (ammonium formate, potassium formate, and sodium formate) was investigated. The effects of formate salts on the linear swelling ratio and zeta potential of the clay minerals were studied. The experimental results showed that ammonium formate could effectively recover the rare earth elements from weathered crust elution-deposited rare earth as well as inhibit the leaching of impurity aluminum. At room temperature, when the ammonium formate concentration was 1% wt, the leaching efficiencies of rare earth and aluminum were 87 and 37%, respectively. Compared with traditional inorganic ammonium salts, the inhibition effect of impurity aluminum was obvious. In addition, the results of the linear swelling ratio in the clay minerals showed that the inhibit ability of formate salts on the hydration of clay minerals enhanced with the increase of the formate concentration, and the order of the inhabitation on the clay minerals followed: 1% ammonium formate > 1.5% potassium formate > 2.5% sodium formate > distilled water. Based on the double layer theory, ammonium formate and potassium formate could effectively compress clay mineral particles to avoid water intake, which could increase the interaction between clay mineral particles and greatly reduce the electronegative property of the clay minerals, so as to effectively reduce the surface hydration of clay minerals to decrease the swelling of rare earth ore. The results of this experiment have important and practical significance in guiding the prevention of landslides, promoting the in-situ leaching technology, and effectively protecting the ecological environment in mining areas.

Published: December 2020

Stage conversion is a critical life cycle feature for several Apicomplexan parasites as the ability to switch between life forms is critical for replication, dissemination, pathogenesis and ultimately, transmission to a new host. In order for these developmental transitions to occur, the parasite must first sense changes in their environment, such as the presence of stressors or other environmental signals, and then respond to these signals by initiating global alterations in gene expression. As our understanding of the genetic components required for stage conversion continues to broaden, we can better understand the conserved mechanisms for this process and unique components and their contribution to pathogenesis by comparing stage conversion in multiple closely related species. In this review, we will discuss what is currently known about the mechanisms driving stage conversion inToxoplasma gondiiand its closest relativesHammondia hammondiandNeospora caninum. Work by us and others has shown that these species have some important differences in the way that they (1) progress through their life cycle and (2) respond to stage conversion initiating stressors. To provide a specific example of species-specific complexities associated with stage conversion, we will discuss our recent published and unpublished work comparing stress responses inT. gondiiandH. hammondi.
ChREBP-Mediated Regulation of Lipid Metabolism: Involvement of the Gut Microbiota, Liver, and Adipose Tissue
Authors: Iizuka Katsumi , Takao Ken , Yabe Daisuke
Published: December 2020

Carbohydrate response element-binding protein (ChREBP) plays an important role in the development of type 2 diabetes, dyslipidemia, and non-alcoholic fatty liver disease, as well as tumorigenesis. ChREBP is highly expressed in lipogenic organs, such as liver, intestine, and adipose tissue, in which it regulates the production of acetyl CoA from glucose by inducingPklrandAcylexpression. It has recently been demonstrated that ChREBP plays a role in the conversion of gut microbiota-derived acetate to acetyl CoA by activating its target gene,Acss2, in the liver. ChREBP regulates fatty acid synthesis, elongation, and desaturation by inducingAcc1andFasn, elongation of long-chain fatty acids family member 6 (encoded byElovl6), andScd1expression, respectively. ChREBP also regulates the formation of very low-density lipoprotein by inducing the expression ofMtp. Furthermore, it plays a crucial role in peripheral lipid metabolism by inducing Fgf21expression, as well as that ofAngptl3andAngptl8, which are known to reduce peripheral lipoprotein lipase activity. In addition, ChREBP is involved in the production of palmitic-acid-5-hydroxystearic-acid, which increases insulin sensitivity in adipose tissue. Curiously, ChREBP is indirectly involved in fatty acid β-oxidation and subsequent ketogenesis. Thus, ChREBP regulates whole-body lipid metabolism by controlling the transcription of lipogenic enzymes and liver-derived cytokines.

This study aims to provide the technoeconomic aspects of two clean processes for biodiesel production. The first process utilizes waste cooking oil as a feedstock and potassium hydroxide as a homogeneous catalyst. The second process uses cement kiln dust heterogeneous catalyst and virgin soybean oil. A comparison was performed between the results of the technical and economic assessments to determine the more feasible process. Theoretical purities of biodiesel and glycerol obtained upon conducting the simulation of both processes are high, i.e., 99.99%. However, the homogeneous process is economically superior as its payback period is slightly more than 1 year while the return on investment is higher than 74%, and the unit production cost is USD 1.067/kg biodiesel. Sensitivity analysis revealed that the profitability of biodiesel production is very sensitive to the feedstock price and recommends shifting toward waste vegetable oils as a cheap feedstock to have a feasible and economic process.
Climate as an Evolutionary Driver of Nest Morphology in Birds: A Review
Authors: Perez Daniela M. , Gardner Janet L. , Medina Iliana
Published: December 2020

Avian nests are critical for successful reproduction in birds. Nest microclimate can affect egg development, chick growth and fledgling success, suggesting that nest building behavior should be under strong selective pressure to nesting conditions. Given that the internal microclimate of the nest is critical for avian fitness, it is expected that nest morphology is shaped by the local environment. Here we review the relationship between nest morphology and climate across species’ distributions. We collate growing evidence that supports a link between environmental conditions and particular nest traits, within species and across species. We discuss the degree to which phenotypic plasticity in nesting behavior can contribute to observed variation in nest traits, the role of phylogenetic history in determining nest morphology, and which nest traits are likely to be influenced by climatic conditions. Finally, we identify gaps in our understanding of the evolution of nest morphology and suggest topics for future research. Overall, we argue that nests are part of the extended phenotype of a bird, they play a crucial role in their reproductive success, and may be an important factor in determining which species will be able to persist in the face of ongoing climate change.
