Published: August 2021

Introduction:The incidence of breast cancer has increased every year, mostly in developing countries. However, breast cancer awareness in women is still insufficient. A woman must be aware of breast cancer disease earlier. This study aimed to describe breast cancer awareness in female adolescents.Methods: The research design was used descriptive-analytic. The study population consisted of female adolescents in 10th-11th grade at Vocational High School in Surabaya, East Java, Indonesia. The sample was taken using stratified random sampling. There are 206 female adolescents aged 15-18 years old who participated in this study. Data collected using a self-structured breast cancer awareness questionnaire arranged by Breast Cancer Awareness Measurement (BCAM) guideline. The questionnaire consisted of breast cancer knowledge (disease, signs and symptoms, risk factors), perception, and BSE. The statistical analysis was using distribution frequency.Results: The result presented that the majority of female adolescents had high awareness (67,5%). The maximum score was knowledge of disease (3.28 ± 0.54) (table 3). The minimum score was risk factors knowledge (1.95 ± 0.69) and BSE (1.81 ± 0.78).Conclusion: The respondents have good knowledge of breast cancer disease yet understanding of risk factors is low. It is necessary to do counseling programs in school, particularly women's reproductive health and breast self-examination (BSE) due to improve knowledge of risk factors in female adolescents.

Abstract
Most of the studies investigating the relationship between socioeconomic status and the occurrence of COVID-19 have limitations due to their ecological design. To investigate the relationship between socioeconomic status and individual-level risk of developing COVID-19, we conducted a population-based, age and gender matched, case-control study in a district of Istanbul. The case group was defined as all confirmed COVID-19 cases (n=232) in the district in a week of August 2020. The control group was matched with cases in terms of age and gender and selected randomly from the directory of the same primary care provider in the district in a 1:1 ratio. The socioeconomic status was measured by the Turkish Socioeconomic Status Index which considers its three dimensions: education, occupation, and income. 168 cases (72.4% response) and 168 controls are included in the study. The mean socioeconomic status score is 70.28±7.09 for cases and 69.25±7.46 for controls (p=0.201). 15.2% (n=25) of cases and 22.4% (n=37) of controls is in lower socioeconomic status group (p=0.091). The analysis did not reveal a statistically significant difference between study groups. Socioeconomic status may not a significant predictor of COVID-19 occurrence at the individual-level. The disease seems to be a common threat to all individuals.

Authors: Matheka Duncan Mwangangi , Walong Edwin , Jowi Christine Yuko 
Published: August 2021

Abstract
BackgroundAngiofibromas are benign but locally aggressive vascular tumours that commonly occur in the nasopharynx, neck and face. Angiofibromas located in sites other than head and neck regions are rare. We report a massive interventricular tumour in a 5-month-old who died suddenly.Case presentationWe present a 5-month-old who died suddenly due to a massive rare cardiac tumour. A post mortem carried out diagnosed it as angiofibroma on histopathology. At three months of age, he had a persisting cough for a week, with associated occasional wheezing and dyspnea that stopped after symptomatic treatment. A chest x-ray revealed a mild cardiomegaly. Serial echocardiograms showed a well circumscribed, homogenous, highly vascularized mass filling the left ventricle. Surgical intervention was planned.Conclusions: Cardiac angiofibromas are rare pediatric neoplasms and as seen in this report, invariably fatal. More insights into their pathogenesis, prevention and treatment are required.
Gravity cells as a necessary link in string theory. The formula for the gravitational constant, the formula for the mass of the electron, the formula for the minimum distance of the gravitational interaction. The coincidence of the results obtained by the formulas and the experimental data.
Authors: Chernov Andrey 
Published: August 2021

Abstract
In this study, a new concept is introduced into physics - gravitational cells. The gravitational cell hypothesis was organically integrated into string theory. As a result, using the Schwarzschild radius formula and the Coulomb formula, a gravitational formula in the region of black holes was obtained on the basis of two fundamental constants, and its exact value was determined. The value of the "usual" gravitational constant was also confirmed and the mass of the gravitational cell was obtained. The introduction of the hypothesis of gravitational cells into string theory made it possible to apply Planck's formula to gravitational interaction. As a result, a formula for the energy of a gravitational quantum and a formula for the vibrational velocity of a gravitational string were obtained. On this basis, the formula for the mass of the electron was obtained and its value was calculated, which coincided with the experimental mass of the electron. The exact minimum distance of the gravitational interaction was determined by the formula for the vibrational velocity of the gravitational string. This calculated minimum distance completely coincided with the known experimental data obtained when determining the Casimir effect (force).

Published: August 2021

Abstract
In this research, the application of mesoporous carbon CMK-3 and modified CMK-3 (M-CMK-3) to improve antifouling and rejection rate of polyethersulfone NF membrane was assessed. CMK-3 was modified with H-acid to increase hydrophilic characteristics of CMK-3. The synthesized CMK-3 and modified CMK-3 membranes exhibited a high pure water flux and also flux recovery ratio (up to 95%) compared with bare NF membrane. Also, the membranes with optimum additive loading (0.1wt%) of CMK-3 and M-CMK-3 were compared to reject different salts and dyes. From the obtained results, the membrane embedded with M-CMK-3 showed higher rejection rate rather than bare NF membrane (up to 95 % for Na2SO4and 64% for CaCl2) and also the flux permeability was increased from 6.44 for bare NF membrane to 20.11 kg/m2.h for the membrane embedded with M-CMK-3. A higher rejection data for different dyes under different pH conditions (up to 90%) was reported for the synthesized membrane embedded with M-CMK-3. After all, from the obtained data, M-CMK-3 with higher negative surface charge presented a higher performance to remove salts and dyes. This research was aimed to develop cost-effective NF membranes with high antifouling properties and super high filtration capacity for removing dyes and salts from wastewaters.
A Preliminary Study On The Relationship Between Humoral Immunity And Mortality Based On Climatic Factors

Published: August 2021

Abstract
Background: Climate affects cell-mediated cellular immunity and antibody mediated humoral immunity. As basic units of humoral immunity, antibodies regulate pathogens and prevent infection, which affect human health. However, the influence of atmospheric temperature and temperature differences on antibodies is still unclear. We provide basic evidence on this topic by analyzing the effects of ambient temperature on immune indexes and mortality.Method: Based on the physical examination data of a general hospital in a large city in China from January 1, 2018 to December 31, 2019, we analyzed the influence of atmospheric temperature and temperature differences from climatic factors on the concentrations of four kinds of antibodies (IgA, IgM, IgG and IgE) through an epidemiological survey. Relationships between the atmospheric temperature and mortality in the hospital and city were also discussed. On this basis, we explored the relationship between each immunoglobulin and the mortality rate in the hospital and city. To further verify the effects of ambient temperature on IgE related to respiratory system immunity, we designed a field experiment with an artificial environment near the human thermal comfort zone.Results: The changes of IgM and IgE have seasonal characteristics. There was a significantly positive correlation between ambient temperature and IgE concentration related to respiratory immunity in natural and artificial environments (natural environment: P=0.021, R 2 =0.428 in; artificial environment: P=0.009, Spearman=−0.495). The IgM and IgE levels were the inverted "U" type with the temperature difference, while the IgA and IgG levels were the "fishbone" type. The IgM and IgE concentrations were the highest when the temperature difference was equal to zero. The mortality rate of the hospital and city was U-shaped with the season, and the mortalities were strongly negatively correlated with local atmospheric temperature (hospital: P=0.006, Spearman=-0.544**; city P = 0.000, Spearman = 0.743 **). The concentration of IgE related to respiratory system immunity was significantly negatively correlated with the hospital and city mortalities (hospital: P=0.014; city: P=0.048). IgE levels can be used as a biological parameter to predict death.Conclusions: Low temperature and large increases or decreases in temperature are not conducive to the secretion of antibodies, especially IgE related to respiratory immunity, which can increase the mortality rate to some extent. In the future, based on the findings of our artificial environment study, the span between stressors can be narrowed to determine the temperature range that can cause changes in antibody concentrations. Thus, the duration and lag time of the influence of each temperature on human immune indexes were studied, as well as how the immune indexes changed.

Abstract
Cotton fabric is widely used in many occasions, but it is flammable with high fire risk. To meet the great fire safety demands of cotton fabric, a novel lignocellulosic-based P-N synergistic (LFPN) flame-retardant coating with high efficiency and environment friendly was developed via mechanochemistry strategy in the aqueous phase. The characterisation results showed the stable P-O-C bond formed to bind both lignocellulosic fibre and ammonium polyphosphate (APP). Meanwhile, LFPN has an excellent dispersion in water with a nanometer-scale enveloping rod structure. The cotton fabric treated by the LFPN coating showed outstanding flame-retardant properties, the peak heat release rate (PHRR) was reduced by 77% and the residue mass was increased by 259% compared with control cotton fabric. And there was a self-extinction phenomenon during the flammability test of flame retardant cotton. Based on the analysis of the combustion and pyrolysis process, a gas-condensed two-phase flame retardant mechanism model was proposed, which could be used to explain the action process of LFPN for cotton fabric during combustion.

Abstract

BackgroundPrevious studies have shown that transmembrane protease serine 3 (TMPRSS3) is abnormally expressed in various tumours and its expression is closely related to tumorigenesis and progression [1-3]. However, there have been no reports regarding the role of TMPRSS3 in colorectal cancer (CRC). The aim of the current study was to comprehensively explore the clinical value of TMPRSS3 on the radioresistance of CRC.MethodsIn this study, we evaluated the expression level of TMPRSS3 in radioresistant CRC tissues as well as CRC tissues by analysing public data sets from the Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), ArrayExpress, and GTEx databases, as well as explored the relationship between TMPRSS3 and lymph node metastasis, distant metastasis, and prognosis. In addition, we investigated the biological function of TMPRSS3 by gene ontology (GO) and analysis of the Kyoto Encyclopaedia of Genes and Genomes (KEGG). Finally, we created a protein-protein interaction (PPI) network to identify hub genes that may function in concert with TMMPRSS3.ResultsEight radiation-processed CRC tissue data sets and 26 CRC mRNA data sets were obtained. The pooled analysis revealed that TMPRSS3 was significantly highly expressed in CRC radioresistant tissues—SMD = 0.38 (95% CI: 0.14~0.63; p-value < 0.05). In addition, TMPRSS3 is also as highly expressed in CRC tissues—SMD = 1.55 (95% CI: 1.20~1.90; p-value < 0.05). Subsequently, we explored the relationship between TMPRSS3 and both metastasis and prognosis. The results revealed no relationship between TMPRSS3 and lymph node metastasis and distant metastasis (p-value > 0.05). Furthermore, pooled analysis of HR revealed that TMPRSS3 could be used as a risk factor for DFS—SMD = 1.28 (95% CI: 1.03~1.60; p-value < 0.05). Finally, we obtained 429 co-expressed genes for bioinformatics analysis and selected a total of four hub genes: MSLN, MFI2, CKAP4, and PXN. The results revealed that these genes cooperate with TMPRSS3 to participate in biological processes, such as CRC development, metastasis, and radioresistance by affecting autophagy, cell-cell adhesion, and extracellular matrix breakdown.ConclusionThis study reveals that TMPRSS3 has potential as a new biomarker and radioresistant therapeutic target for CRC and also has a few implications for the prognosis of CRC patients. However, this conclusion must be further experimentally verified.
Version up-date: The CDKN2B-AS1/ MIR497/TXNIP axis regulated macrophages
Authors: Xu JianZhong 
Published: August 2021

Abstract
The polarization of macrophages plays a critical role in the pathophysiology of rheumatoid arthritis. The macrophages can have pro-inflammatory M1 polarization and various types of alternative anti-inflammatory M2 polarization. Our preliminary results showed that the CDKN2B-AS1/MIR497/TXNIP axis might regulate macrophages of rheumatoid arthritis patients. Therefore, we hypothesized that this axis regulated the polarization of rheumatoid macrophages. Flow cytometry was used to determine the surface polarization markers in M1 or M2 macrophages from healthy donors and rheumatoid arthritis patients. The QPCR and Western Blotting were used to compare the expression of the CDKN2B-AS1/MIR497/TXNIP axis in these macrophages. We Knocked down and overexpressed the axis in the macrophage cell line MD to test its roles in macrophage polarization. Compared to cells from healthy donors, cells from rheumatoid arthritis patients expressed higher levels of CD40 and CD80 and lower levels of CD16, CD163, CD206, and CD200R after polarization, they also expressed higher CDKN2B-AS1, lower MIR497, and higher TXNIP. In macrophages from healthy donors, there was no correlation among CDKN2B-AS1, MIR497, and TXNIP. But in macrophages from patients, there were significant correlations. The CDKN2B-AS1 knockdown, MIR497 mimics suppressed the M1 polarization but promoted the M2 polarization in MD cells, while the MIR497 knockdown and the TXNIP overexpression did the opposite. This study demonstrated that elevated CDKN2B-AS1 in macrophages promotes the M1 polarization and inhibited the M2 polarization of macrophages by the CDKN2B-AS1/ MIR497/TXNIP axis.

Published: August 2021

Abstract
Insufficient understanding of the mechanism that reversibly converts sulphur into lithium sulphide (Li2S) via soluble polysulphides (PS) hampers the realization of high performance lithium-sulphur cells. Typically Li2S formation is explained by direct electroreduction of a PS to Li2S; however, this is not consistent with the size of the insulating Li2S deposits. Here, we use in situ small and wide angle X-ray scattering (SAXS/WAXS) to track the growth and dissolution of crystalline and amorphous deposits from atomic to sub-micron scales during charge and discharge. Stochastic modelling based on the SAXS data allows quantification of the chemical phase evolution during discharge and charge. We show that Li2S deposits predominantly via disproportionation of transient, solid Li2S2 to form primary Li2S crystallites and solid Li2S4 particles. We further demonstrate that this process happens in reverse during charge. These findings show that the discharge capacity and rate capability in Li-S battery cathodes are therefore limited by mass transport through the increasingly tortuous network of Li2S / Li2S4 / carbon pores rather than electron transport through a passivating surface film.

Abstract
Indian economy has experienced an enormous change in employment from the independence. Employment totally based on the skills and requirement of the profile gives contributing to major portion to our national income. However, the earning inequality in India has unfavorably obstructed underprivileged in accessing elementary needs like health and education. Periodic labour force survey (PLFS) conducted by National Statistical Office of India generates estimates on earning status at national and state level for both rural and urban sectors separately. This paper demonstrates disaggregate level disparities in earning distribution classified by gender and occupational categories in Indo-Gangetic Plain region of India which includes Bihar, Punjab, Haryana, Uttar Pradesh and West Bengal. This analysis helps in distinguishing the disparities in earning distribution between rural and urban sector in this region classified by gender and occupational categories which often masked at further down the level of disaggregation. This study of earning disparities is directly pertinent for measuring and monitoring the sustainable development goal 8 and 10 and expected to offer extraordinary evidence to policy-makers for recognizing the areas demanding additional consideration.
Data-driven asset management in urban water pipe networks: a proposed conceptual framework
Authors: Okwori E. , Pericault Y. , Ugarelli R. , Viklander M. , Hedström A. 
Published: August 2021

Abstract
Analytical tools used in infrastructure asset management of urban water pipe networks are reliant on asset data. Traditionally, data required by analytical tools has not been collected by most water utilities because it has not been needed. The data that is collected might be characterised by low availability, integrity and consistency. A process is required to support water utilities in assessing the accuracy and completeness of their current data management approach and defining improvement pathways in relation to their objectives. This study proposes a framework to enable increased data-driven asset management in pipe networks. The theoretical basis of the framework was a literature review of data management for pipe network asset management and its link to the coherence of set objectives. A survey to identify the current state of data management practice and challenges of asset management implementation in five Swedish water utilities and three focus group workshops with the same utilities was carried out. The main findings of this research were that the quality of pipe network datasets and lack of interoperability between asset management tools are drivers for creating data silos between asset management levels, which may hinder the implementation of data-driven asset management. Furthermore, these findings formed the basis for the proposed conceptual framework. The suggested framework aims to support the selection, development and adoption of improvement pathways to enable increased data-driven asset management in municipal pipe networks. Results from a preliminary application of the proposed framework are also presented.

Published: August 2021

Abstract
The different shapes of bridge piers across rivers have a great influence on the river water movement, and the study of the influence of pier morphology changes on the water movement characteristics is of great value for bridge design and river flooding. The hydrodynamic model can effectively simulate and predict the changes of river flow patterns, which can provide scientific data support for river management. This paper constructs a hydrodynamic model based on MIKE21 and applies it to the numerical simulation of river hydrodynamics in the lower reaches of the Yellow River, taking elliptical piers as an example, and simulates the effect of the change of pier morphology on the flow velocity, water level and flow field of the river. The results show that the effect of elliptical pier morphology on the flow characteristics of the river channel is significant; under the same flow rate, the congestion value of the pier at the maximum axis ratio is 1.65 times the minimum axis ratio, and the larger the axis ratio, the more serious the congestion; the difference in flow velocity at the maximum axis ratio can reach 2.33 times the minimum axis ratio.
