Authors: Ye Shicai , Sun Bilan , Wu Weiyun , Yu Caiyuan , Tian Ting , Lian Zhongxiong , Liang Qianyi , Zhou Yu
Published: July 2020

Colon cancer is one of the major causes of cancer-related deaths worldwide. Long non-coding RNA (lncRNA) LINC01123 has been suggested to act as an oncogene in non-small cell lung cancer and a prognostic signature in head and neck squamous cell carcinoma. However, its role in colon cancer remains obscure. From TCGA database, LINC01123 was observed to be up-regulated in colon adenocarcinoma (COAD). Subsequently, the up-regulated LINC01123 was also detected in colon cancer cells. Functionally, LINC01123 could enhance cell proliferation, migration, invasion and angiogenesis. Moreover, the chemoresistance of colon cancer cells was verified to be promoted by LINC01123. Afterward, LINC01123 was found to bind with Ago2 and miR-34c-5p. Besides, miR-34c-5p was confirmed to inhibit the cellular process and chemoresistance of colon cancer cells. Then, VEGFA was disclosed to coexist with LINC01123 and miR-34c-5p in RNA-induced silencing complex. And TCGA database suggested that its expression was correlated with different stages of COAD. Moreover, it was uncovered that VEGFA could bind with miR-34c-5p and its expression positively correlated with LINC01123 expression. Finally, LINC01123 was proofed to regulate colon cancer progression and cells chemoresistance via VEGFA. In conclusion, LINC01123/miR-34c-5p/VEGFA axis promotes colon cancer malignancy and cells chemoresistance.

Authors: Zhao Xin , Cao Di , Ren Zhangyong , Liu Zhe , Lv Shaocheng , Zhu Jiqiao , Li Lixin , Lang Ren , He Qiang
Published: July 2020

Background: Hypermethylation of gene promoters plays an important role in tumorigenesis. The present study aimed to identify and validate promoter methylation-driven genes (PMDGs) for pancreatic ductal adenocarcinoma (PDAC). Methods: Based on GSE49149 and the PDAC cohort of The Cancer Genome Atlas (TCGA), differential analyses of promoter methylation, correlation analysis, and Cox regression analysis were performed to identify PMDGs. The promoter methylation level was assessed by bisulfite sequencing polymerase chain reaction (BSP) in paired tumor and normal tissues of 72 PDAC patients. Kaplan−Meier survival analyses were performed to evaluate the clinical value of PMDGs. Results: In GSE49149, the β-value of the dipeptidyl peptidase like 6 (DPP6) promoter was significantly higher in tumor compared with normal samples (0.50 vs. 0.24, P<0.001). In the PDAC cohort of TCGA, the methylation level of the DPP6 promoter was negatively correlated with mRNA expression (r = −0.54, P<0.001). In a multivariate Cox regression analysis, hypermethylation of the DPP6 promoter was an independent risk factor for PDAC (hazard ratio (HR) = 543.91, P=0.002). The results of BSP revealed that the number of methylated CG sites in the DPP6 promoter was greater in tumor samples than in normal samples (7.43 vs. 2.78, P<0.001). The methylation level of the DPP6 promoter was moderately effective at distinguishing tumor from normal samples (area under ROC curve (AUC) = 0.74, P<0.001). Hypermethylation of the DPP6 promoter was associated with poor overall (HR = 3.61, P<0.001) and disease-free (HR = 2.01, P=0.016) survivals for PDAC patients. Conclusion: These results indicate that DPP6 promoter methylation is a potential prognostic biomarker for PDAC.
Elevated long noncoding RNA MALAT-1 expression is predictive of poor prognosis in patients with breast cancer: a meta-analysis
Authors: Wang Yanyan , Zhang Yujie , Hu Kaimin , Qiu Jili , Hu Yue , Zhou Meiqi , Zhang Suzhan
Published: July 2020

Accumulating evidence indicates that aberrant regulation of metastasis-associated lung adenocarcinoma transcript 1 (MALAT-1), a long noncoding RNA (lncRNA), plays a vital role in tumorigenesis. However, its association with breast cancer has not been systematically evaluated. In the current study, a meta-analysis was conducted to clarify the association between MALAT-1 and the prognosis and clinicopathological features of breast cancer. Relevant literature published in several databases was searched. Hazard ratio (HR) and odds ratio (OR) with 95% confidence interval (CI) were calculated to evaluate the effect of MALAT-1 expression on the survival outcomes and clinicopathological features of breast cancer. A total of 12 studies involving 4106 patients were identified. Pooled HR demonstrated that elevated MALAT-1 expression significantly predicted unfavorable overall survival (HR = 2.06, 95% CI: 1.66–2.56, P<0.0001) in patients with breast cancer. Subgroup analysis stratified by cancer type, sample size, and method of variance analysis also showed statistically significant associations. Additionally, the HR of patients with up-regulated MALAT-1 expression concerning disease-free survival (DFS), recurrence-free survival (RFS), and disease-specific survival (DSS) was 1.91 (95% CI: 1.53–2.39, P<0.0001). Further, elevated MALAT-1 expression was positively correlated with the progesterone receptor (PR) status (OR = 1.47, 95% CI: 1.18–1.82). Thus, MALAT-1 is a promising biomarker for predicting survival outcomes in patients with breast cancer.

Authors: Lyu Mengyuan , Zhou Jian , Cheng Yuhui , Chong Weelic , Wu Kang , Fang Teng , Fu Tianbo , Ying Binwu
Published: July 2020

Objective: This review aimed to identify proper respiratory-related sample types for adult and pediatric pulmonary tuberculosis (PTB), respectively, by comparing performance of Xpert MTB/RIF when using bronchoalveolar lavage (BAL), induced sputum (IS), expectorated sputum (ES), nasopharyngeal aspirates (NPAs), and gastric aspiration (GA) as sample.

Methods: Articles were searched in Web of Science, PubMed, and Ovid from inception up to 29 June 2020. Pooled sensitivity and specificity were calculated, each with a 95% confidence interval (CI). Quality assessment and heterogeneity evaluation across included studies were performed.

Results: A total of 50 articles were included. The respective sensitivity and specificity were 87% (95% CI: 0.84–0.89), 91% (95% CI: 0.90–0.92) and 95% (95% CI: 0.93–0.97) in the adult BAL group; 90% (95% CI: 0.88–0.91), 98% (95% CI: 0.97–0.98) and 97% (95% CI: 0.95–0.99) in the adult ES group; 86% (95% CI: 0.84–0.89) and 97% (95% CI: 0.96–0.98) in the adult IS group. Xpert MTB/RIF showed the sensitivity and specificity of 14% (95% CI: 0.10–0.19) and 99% (95% CI: 0.97–1.00) in the pediatric ES group; 80% (95% CI: 0.72–0.87) and 94% (95% CI: 0.92–0.95) in the pediatric GA group; 67% (95% CI: 0.62–0.72) and 99% (95% CI: 0.98–0.99) in the pediatric IS group; and 54% (95% CI: 0.43–0.64) and 99% (95% CI: 0.97–0.99) in the pediatric NPA group. The heterogeneity across included studies was deemed acceptable.

Conclusion: Considering diagnostic accuracy, cost and sampling process, ES was a better choice than other sample types for diagnosing adult PTB, especially HIV-associated PTB. GA might be more suitable than other sample types for diagnosing pediatric PTB. The actual choice of sample types should also consider the needs of specific situations.
The ablation of gas clouds by blazar jets
Authors: Heil Jonathan , Zacharias Michael
Published: July 2020

Context. Flaring activity in blazars can last for vastly different timescales, and it may be the result of density enhancements in the jet flow that result from the intrusion of an interstellar cloud into the jet.

Aims. We investigate the lightcurves expected from the ablation of gas clouds by the blazar jet under various cloud and jet configurations.

Methods. We derived the semi-analytical formulae describing the ablation process of a hydrostatic cloud and performed parameter scans of artificial set-ups over both cloud and jet parameter spaces. We then used parameters obtained from measurements of various cloud types to produce lightcurves of these cloud examples.

Results. The parameter scans show that a vast zoo of symmetrical lightcurves can be realized. Both cloud and emission region parameters significantly influence the duration and strength of the flare. The scale height of the cloud is one of the most important parameters as it determines the shape of the lightcurve. In turn, important cloud parameters can be deduced from the observed shape of a flare. The example clouds result in significant flares lasting for various timescales.
Broad line region and black hole mass of PKS 1510-089 from spectroscopic reverberation mapping
Authors: Rakshit Suvendu
Published: July 2020

Reverberation results of the flat spectrum radio quasar PKS 1510-089 from 8.5 years of spectroscopic monitoring carried out at Steward Observatory over nine observing seasons between December 2008 and June 2017 are presented. Optical spectra show strong Hβ, Hγ, and Fe II emission lines overlying on a blue continuum. All the continuum and emission line light curves show significant variability with fractional root-mean-square variations of 37.30 ± 0.06% (f5100), 11.88 ± 0.29% (Hβ), and 9.61 ± 0.71% (Hγ); however, along with thermal radiation from the accretion disk, non-thermal emission from the jet also contributes to f5100. Several methods of time series analysis (ICCF, DCF, von Neumann, Bartels, JAVELIN, χ2) are used to measure the lag between the continuum and line light curves. The observed frame broad line region size is found to be 61.1−3.2+4.0 (64.7−10.6+27.1) light-days for Hβ (Hγ). Using the σline of 1262 ± 247 km s−1 measured from the root-mean-square spectrum, the black hole mass of PKS 1510-089 is estimated to be 5.71−0.58+0.62 × 107 M⊙.

Authors: Zhou Bin , Lin Li
Published: July 2020

To obtain high-quality bionic design scheme of product form, this paper explores the matching relationship between users’ biological form features and their images from the level of implicit cognition, providing objective basis for effective selection of ideographic biological form features in bionic design of product form. The eye movement experiment was used to screen the biomorphic feature group that was focused on. Questionnaire survey and cluster analysis were used to obtain the main image phrases of the morphological feature group. The two collected materials were combined with implicit cognitive measurement (IAT) to obtain the response time data of the subjects in the classification task. According to Greenwald’s method to verify the effectiveness of the data as a whole, the response time of the combination of various features and images in the compatibility group is sorted to obtain the design guidance conclusion. Taking the white shouldered eagle as an example, the experimental data showed high validity by t-test, and the implicit effect value of the compatibility group was 0.68. According to the analysis of the data, the main image that most matches the head shape characteristics of the white shouldered eagle is “Ferocious”, and the main image that most matches the wing shape characteristics is “Lightsome”, and there is no difference in the implicit cognitive attitude between men and women. The designer takes this as the design reference to improve the effectiveness of the design output. This study can provide more objective suggestions for the bionic design of the related product shape.

Die transforaminale sacrale Stressfraktur bei einem 33-jährigen Langstreckenläufer
Authors: Husen Martin
Published: July 2020

Lumbale und iliosacrale Schmerzen treten gehäuft bei Leistungssportlern, insbesondere bei Läufern auf. Obwohl Stressfrakturen bei Läufern im Bereich der unteren Extremität auftreten, sind sie auch, seltener, im Bereich des Beckens oder der unteren Wirbelsäule zu finden. Nicht selten kommt es bei unspezifischen Symptomen zu einer späten Diagnosestellung. Bei den meisten Patientinnen und Patienten mit sacralen Stressfrakturen handelt es sich um junge, körperlich aktive Patienten, meist Frauen. Wir stellen in diesem Bericht den Fall eines 31-jährigen, männlichen Langstreckenläufers vor, welcher sich inital mit persistierenden Schmerzen im Lumbal-, Sacral- und Gesäßbereich vorstellte. In den Wochen zuvor hatte er seine Trainingseinheiten gesteigert. Die Diagnose wurde letztlich mittels MRT des Beckens gestellt, woraufhin eine konservative Therapie eingeleitet wurde. Die Symptome sistierten nach 3 Monaten. Eine Verlaufskontrolle mittels MRT nach 6 Monaten konnte keine Residuen der Fraktur mehr darstellen.

SCD use was assessed through the Kendall SCD 700 series compliance meter, which tracks the time the SCD machine takes within the monitoring interval. Recruitment occurred after 60 to 80 hours of monitoring, at which time a patient survey was completed. SCD use was the percentage of time the machine was on during monitoring. Mann–Whitney U and Chi-square tests were used to compare associations between SCD use, education, and pharmacologic prophylaxis.

Results Among 125 recruited women, 123 provided adherence data, 69 before and 54 after the education. Median SCD use was 17.3% before and 20.7% after (p = 0.71). Pharmacologic prophylaxis use was similar between the two periods and was not associated with SCD use. Among 121 surveys, the most common reason as to why SCDs were not worn was prevention of walking (52/121 [43.0%]).

Conclusion Using a novel monitoring technique, we found low-SCD use among antepartum inpatients, which was neither affected by education nor concurrent pharmacologic prophylaxis. Improving mobility with SCDs may improve use in this population.

Key Points
Fractal lattice as an efficient thermoelectric device
Authors: Chakraborty Suvendu , Maiti Santanu K.
Published: July 2020

Figure of merit is an essential quantity to describe the efficiency of a thermoelectric device and asymmetry in transmission probability is the main requirement to increase the efficiency. Keeping this fact in the mind, here we choose a Sierpinski Gasket (SPG) triangle, a nice example of fractal lattice, as the functional element since it has peculiar energy spectrum compared to the traditional elements. In the framework of tight binding (TB) model we calculate all the thermoelectric quantities using Landauer’s prescription. The atypical and strange behavior of transmission function can be further modified by incorporating asymmetry in the hopping integrals of the SPG network. Here, we acquire a remarkably large value of thermoelectric efficiency from the system and we strongly believe that our work can be verified by a suitable experimental setup. The present analysis can easily be generalized in other similar kind of fractal lattices having multiple loops.
High figure of merit in an ac driven graphene nanoribbon
Authors: Ganguly Sudin , Maiti Santanu K.
Published: July 2020

Generally, pristine graphene nanoribbons show poor thermoelectric (TE) performance. Several proposals are available to enhance the TE performance, which however requires some highly structural modifications of the system. In the present work, we explore a new prescription where a favorable TE response can be achieved by irradiating the ribbon. The electronic conductance, thermopower and thermal conductance due to electron are found to be highly sensitive to the irradiation. We obtain significantly enhanced thermopower along with highly suppressed thermal conductance for typical sets of irradiation parameters. As a result of this higher figure of merit is found. Therefore, we can suggest that a graphene nanoribbon can be used as an efficient energy conversion device in the presence of irradiation and hope that it will bear a significant impact in the energy market soon.
An improved approach to find the height of the accretion disk
Authors: Chatterjee Sangita , Mondal Soumen , Basu Prasad
Published: July 2020

In the present work, we propose an improved approach to find the height of the accretion disks around Kerr black holes. The vertical structure of the disk is obtained using a relativistic continuity equation and finally, the result is expressed in terms of the accretion rate and flow parameters. For different models of thin and slim disks, the expressions of the vertical height of the accretion disk are also been reviewed chronologically. We further discuss the basic assumptions, merits, and demerits of these models. Compared to existing approaches, our analysis is more self-consistent and less axiomatic. Further, we find that disk height is directly proportional to accretion rate which could be important to find out the vertical structure of the accretion disk in different black hole accretion states in a hysteresis cycle.

Miscellaneous Radio Galaxies (MRGs) are very rare kind of radio galaxies that exhibit unusual and different jet alignment and orientation from a typical radio galaxy. The peculiar and unique morphology of this type of radio source makes them a special case of study. In this paper, we report the identification of fifteen MRGs from VLA Faint Images of the Radio Sky at Twenty-Centimeters (VLA FIRST) Survey. The MRGs are identified manually by visual inspection of the FIRST database (December, 2017). The individual radio morphology of each sources are cross-checked at different frequencies from other surveys like TIFR GMRT Sky Survey at 150 MHz and Westerbork Northern Sky Survey at 325 MHz. We also identify the associated optical counterparts from the Sloan Digital Sky Survey (SDSS), where available. The different physical parameters like spectral index and radio luminosity of these MRGs are also estimated. An overview on the origin of these unique sources are also drawn.

Anjungan Pantai Losari is one of the famous public spaces in Makassar; it is a primary landmark in the city. Nevertheless, this public space is considered not optimal because it is only crowded with people’s activities in the afternoon and night. On the other hand, some theories argued that a good public open space has the ability to accommodate various people all day long. This study was conducted to evaluate and to study the effectiveness of public open space using the Good Public Space Index (GPSI). There are six variables used in GPSI: intensity use, the intensity of social use, people’s duration of stay, temporal diversity use, variety of use, and diversity of users. This study found that the average of GPSI value shows the high score of Anjungan Pantai Losari effectiveness. However, two variables, intensity of use and people duration of social use were still at a low level. It was expected that this research could be a reference to develop spatial planning, especially the improvement of public open space quality.

Waste is an endless environmental problem. The amount of waste production has increased due to the increasing population. Besides being produced in a city, waste generation is also produced by universities or campuses. One of them is the Gowa campus, the campus of Faculty of Engineering, Hasanuddin University. Current waste management is carried out by holding, collecting and burning in open areas without further management. It can cause environmental pollution and health problems. The objectives of this study were to determine the amount of campus waste generation, to analyze the needs of incinerators in campus, to determine incinerator tools, and to determine the advantages, disadvantages, efficiency and effectiveness of the incinerators in Gowa Campus. The results showed that the amount of waste generated at the Gowa campus was 0.25 liters/person/day and 0.12 kg/person/day. This incinerator requirements analysis uses the geometry method and the efficiency and effectiveness method. From the calculation, it is known that the use of incinerators for the next ten years is one unit. The disadvantage of using an incinerator is that the cost is very high. However, the advantage is that it can reduce waste generation and overcome environmental and health problems. The comparison between Double Chamber and Maxpell incinerator gave the results that the most effective and efficient is the Maxpell incinerator with an effectiveness of 97.5% and efficiency of 17.17%.

This study was carried out to investigate the effects of prolonged exposure of non-smoking traffic police men to vehicular emission within the northern Gaza Governorate-Palestine. Samples of atmospheric pollutants such as PM10, CO and CO2 were collected alongside respiratory data involving lung function, chest and respiratory status and direct physical examination. This was done in order to understand the level of association between respiratory status such as effect on breathing, upper respiratory tract irritation, frequent cough and eye irritation. Chi-square statistical techniques and descriptive statistics were applied in the datasets. The result shows that there is a strong association between air pollution and respiratory disease with a p-value 0.027 at significance of alfa 0.05. The statistical result shows that about 20 non-smoking traffic policemen have upper respiratory tract infection, 15 with frequent cough symptom, 6 with shortness of breathing and 25 with eye irritation. This study is an indication that vehicular emission within the study area is a primary source of pollution that possesses a risk in exposing non-smoking policemen to series of respiratory diseases. Government agencies and other stakeholders should provide preventive measures in either reducing the number, concentration and sizes of pollutants emitted or provide protective measures to reduce the level of exposure of traffic policemen and other habitants.
