Abstract
The fullerene (C60) is economically significant due to its significant applications in diverse areas like nanochemistry, superconductivity, materials science, etc. The carbon allotrope fullerene C60 and C70 are identified within the thick sequence of black carbonaceous units belonging to the shungite suite of rock at the baryte mine, Mangampet, Andhra Pradesh. Since this is the first of its kind from India's geological material, the exploration of fullerenes enriched barytes from the mines at Mangampet in the Kadapa district is essential. In the present study, remote sensing techniques such as hyperspectral analysis followed by Mixture Tuned Matched Filtering (MTMF) and Support Vector Machine (SVM), and Principal Component Analysis (PCA) were used for exploring the presence of fullerene bearing baryte deposits in the Mangampet mine. The spectra measured for baryte samples were used as reference spectra for deriving true endmember from Landsat OLI and ASTER satellite data. The detailed characterisation of structure and chemistry of the baryte samples were carried out using techniques like Energy Dispersive X-ray Fluorescence (EDXRF), X-ray Powder Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), and Fourier-Transform Infrared Spectroscopy (FTIR) techniques. The High-Performance Liquid Chromatography (HPLC) and Matrix-Assisted Laser Desorption/Ionization (MALDI) mass spectrometry analyses confirm fullerene presence in baryte deposits. The retention time at 11.783–11.822 min obtained from HPLC and high-intensity rate m/z at 720.178 obtained from MALDI spectra suggest fullerene in baryte mine deposits. The remote sensing exploration of fullerene bearing shungite suite of rocks in baryte mineral deposits of Mangampet mine has opened up new research areas for converting this material into value-added products.

Abstract
Aims: This study identified the lipid profile across a full range of poor glycemic control and the association between lipid profiles with different specific glycated hemoglobin (HbA1c) cutoffs in patients with type 2 diabetes (T2DM). Methods: A total of 1183 T2DM patients with poor glycemic control (HbA1c>7%) selected through convenience sampling in three hospitals of Jiangsu province were surveyed during April 2018 and July 2019. Dyslipidemia was defined according to criteria of the Third Report of the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III).Results: The prevalence of dyslipidemia was 55.2 % overall. Of 1183 subjects, 13.0% had high total cholesterol (TC), 33.1% had low high density lipoprotein cholesterol (HDL-C), 9.9% had high low density lipoprotein cholesterol (LDL-C), and 28.4% had high triglycerides (TG) concentrations. There was an increase in frequency of dyslipidemia in patients with different cutoff values of HbA1c (P<0.05). The prevalence of high TC was closely related with different cutoff values of HbA1c (adjusted OR =1.77, 2.56 3.82, respectively). Patients with HbA1c values 9%≤HbA1c<11% and HbA1c≥13% had significantly higher prevalence of dyslipidemia compared with the patients who had 7≤HbA1c<9%.Conclusion: T2DM patients with 9%≤HbA1c<11% and HbA1c≥13% tend to have moderate and severe dyslipidemia respectively, suggesting the importance of glycemic control in normalizing dyslipidemia.

Abstract
Background: Cystic echinococcosis (CE) is a parasitic zoonosis caused by infection with the larval stage of Echinococcus granulosus sensu lato This study investigated the prevalence and potential risk factors associated with human CE in the towns and rural areas of Ñorquinco and Ramos Mexia, Rio Negro province, Argentina. Methods: In order to detect abdominal CE cysts, we screened 892 volunteers by ultrasound and investigated potential risk factors for CE using a standardized questionnaire. Bivariate and multivariate analyses were used to estimate the Prevalence Ratio (PR) and their 95% CIs of the association between CE and the factors investigated. Results: Abdominal CE was detected in 42/892 screened volunteers (4.7%, CI 3.2-6.1), only two of who being under 15 years of age. Thirteen CE (30.9%) cases had 25 cysts in active stages (CE1, CE2, CE3) The most relevant risk factors identified in the bivariate analysis included: live in rural area (p=0.003), age >40 years (p=0.000), drinking always water of natural source (p=0.007), residing in rural areas during first five years of life (p=0.000) and live more than 20 years at your current address (p=0.013). In the multivariate model, statistically significant risk factors were: frequently touch dogs (p=0.012), residing in rural areas during first five years of life (p=0.004), smoking (p=0.000), age > 60 years (p­­=0.002) and live in rural areas (p=0.017).Conclusions: our results point toward infection with CE being acquired since childhood and with constant exposure throughout life, especially in rural areas with a general environmental contamination

Abstract
In the recent past, metal oxides have attracted the researchers because of their applications in energy and environmental application domains. In the present work, hydrothermal technique used to prepared the Sn doped TiO2 nanoparticles and the effect of Sn concentration has been investigated. The structural, morphological, surface composition, optical and photocatalytic behavior were studied. XRD pattern revealed that doping of Sn makes easy transformation of rutile from anatase phase at lower temperature, providing tetragonal structure of rutile of TiO2. TEM analysis showed the formation of nanoparticles with spherical like morphology with good crystallinity. UV-Vis spectra, it is observed that optical absorption edge gets red shifted upon Sn doping and the band gap is found to be 2.6 eV. The photocatalytic activity of the synthesized nanoparticles has been investigated under visible light irradiation. Experimental results suggested that 0.5 wt % of Sn doped nanoparticles have shown to exhibit improved photocatalytic properties.

Abstract
Atherosclerosis is a chronic inflammatory disease characterized by the formation of atheroma plaque in the arterial wall, process that causes long-term obstruction of the arteries. Postmenopausal women tend to have greater body adiposity, factor that corroborate to increased risk of cardiovascular events and development of atherosclerosis. Therefore, the aim of this study was to evaluate the association of experimental model of atherosclerosis with ovarian deprivation and consumption of high-fat diet in metabolic, hemodynamic, and autonomic outcomes. 21 female ApoE-Ko were divided into 3 groups (n = 7 in each): control treated with normolipidic diet (C); ovariectomized treated with normolipidic diet (Ovx); ovariectomized treated with high-fat diet (OvxHF). Hemodynamic parameters, baroreflex sensitivity and cardiovascular autonomic modulation were evaluated. Values (mean ± standard error of mean) were analyzed by One-way ANOVA, followed by Tukey's post hoc (p<0.05). The OvxHF showed increase in final body weight, adipose tissue, tachycardia at rest, in addition, there was a decrease in muscle mass, functional capacity, baroreflex sensitivity associated with less cardiac autonomic modulation. These findings provide evidence about the risk by the loss of ovarian hormones with food consumption and demonstrate the importance of adhering to prevention and treatment strategies.

Abstract
The hyperbolic phonon polaritons supported in hexagonal boron nitride (hBN) exhibiting long scattering lifetimes are advantageous for applications like super-resolution imaging via hyperlensing. Yet, challenges exist in hyperlens imaging to distinguish individual and closely spaced objects and in correlating the complicated hyperlens fields with the structure of an unknown object underneath the hyperbolic material. Here, we make significant strides to overcome each of these three challenges. For the first two, we demonstrate that monoisotopic h11BN (> 99% 11B) provides the ability to experimentally resolve structures as small as 40-nm and those with sub-25-nm spacings, inferring at least 154- and 270- times smaller than free-space wavelength, showing improvements in spatial resolution. We also present an image reconstruction algorithm that provides a structurally accurate, visual representation of the embedded objects using only the hyperbolic dielectric function and thickness as input parameters. Further, we offer additional insights into the frequency dependence for realizing optimal hyperlens performance. Thus, our results significantly advance label-free, high-resolution, spectrally selective hyperlens imaging and image reconstruction methodologies.

Abstract
Background and Purpose— Preterm birth (PTB) is the leading cause of infant mortality in the U.S. and globally. The goal of this study is to increase understanding of PTB risk factors that are present early in pregnancy by leveraging statistical and machine learning techniques on big data. Methods—The 2016 U.S. birth records is obtained and combined with two other area-level datasets, Area Health Resources File and County Health Ranking. Then, we applied multiple machine learning techniques to study a cohort of 3.6 million singleton deliveries to identify generalizable preterm risk factors.Results—The most important predictors of preterm birth are gestational and chronic hypertension, interval since last live birth, and history of a previous preterm birth that can respectively explain 14.91%, 6.92%, and 6.50% of the AUC. Parents education is one of the influential variables in prediction of PTB explaining 10.5% of the AUC. The relative importance of race declines when parents are more educated or have received adequate prenatal care. The gradient boosting machines outperformed other machine learning techniques with an AUC of 0.75 (recall: 0.64, specificity: 0.73) for the validation dataset. Conclusions—Application of ML techniques improved the performance measures in prediction of preterm birth. The results emphasize the importance of socioeconomic factors such as parental education as one of the most important indicators of a preterm birth. More research is needed on the mechanisms through which the socioeconomic factors affect the biological responses.

Abstract
Background: Undifferentiated pleomorphic sarcoma (UPS) in the gastrointestinal tract is rare. According to the diagnostic criteria after the World Health Organization 2013 reclassification, there has been only one case of UPS with perforation of the gastrointestinal tract.Case presentation: A 71-year-old man who was undergoing outpatient chemotherapy at the department of respiratory medicine of our hospital for lung cancer and brain metastasis, was admitted to our hospital with sudden high fever and abdominal pain. A computed tomography scan showed free air in the abdominal cavity with thickening of part of the jejunal wall. We suspected jejunal metastasis of lung cancer and performed emergency surgery for acute peritonitis due to gastrointestinal perforation in the same area. A Bormann type 2 tumor was found in the jejunum with perforation. The histopathological diagnosis was UPS. Ten months have passed since the surgery, and there has been no recurrence of UPS and no significant change in lung cancer.Conclusions: Primary UPS of the gastrointestinal tract is rare, and cases with perforation are extremely rare. Currently, ten months have passed since the surgery, and no recurrence has been observed. We encountered a case of UPS in which it was difficult to distinguish metastasis from lung cancer to the jejunum, and emergency surgery gave us the chance to confirm the definitive diagnosis and save the patient's life.

Abstract
Purpose : This study was to evaluate the value of C-reactive protein (CRP) kinetics and initial apolipoproteinA1 (apoA-I) level as prognostic parameters in advanced non-small Cell Lung Cancer (NSCLC). Methods: Within a retrospective single-center study, serum CRP and apoA-I level were measured at baseline and at the start of each platinum-based chemotherapy cycle for 125 NSCLC patients. Survival analysis, calculated by the Kaplan–Meier method and log-rank test, was used to assess the prognostic significance of Serum CRP and apoA-I level and both levels. The non-parametric Spearman rank correlation coefficient (rs) was used to measure the correlation between apoA-I and CRP. Results: Lung cancer-specific survival were significantly different across three CRP kinetics groups (P<0.001), such significant differences were also seen between different apoA-I groups. In multivariate analysis, both CRP kinetics and apoA-I were independent significant factors for overall survival. Patients in non-normalized CRP group with lower apoA-I had a poor prognosis. Spearman’s rank correlation analysis revealed that the apoA-I level presented a negative correlation with the CRP level during treatment (r= -2.793, P<0.05).Conclusion: CRP kinetics and apoA-I may be useful to predict the prognosis of NSCLC patients treated with first-line platinum-based chemotherapy and facilitate individualized treatment.

Abstract
Background: Dementia is a serious social problem worldwide, and dementia and oral health are closely related. Therefore, we confirmed the relationship between dementia prevention behavior and the oral health behaviors.Methods: The study was conducted by IRB review at Silla University in Korea (No.1041449-201912-HR-002) and decided that 140 people living in South Korea were eligible. The data analysis used IBM SPS ver. 25.0 (IBM Co., Armonk, NY, USA) and compared oral health knowledge, dementia knowledge, Dementia anxiety and dementia prevention behavior according to oral health behavior.Results: As a result, the people with high oral health behavior had high oral health knowledge and was not relevant in dementia knowledge and anxiety. Also, as the oral health behavior increased, oral health knowledge and dementia prevention behavior tended to get improve. As the oral health knowledge increased, dementia anxiety and dementia prevention behavior tended to get improve. Conclusion: Therefore, in order to improve the prevention of dementia, knowledge transfer that dementia is highly relevant to oral health is more important than anything else.

Abstract
Dracocephlum kotschyi Boiss is a genus in Lamiaceae family and a medicinal herb native to Iran. The cell suspension cultures were treated by static magnetic field (SMF) and Fe3O4 magnetite nanoparticles (MNP) to understand the production yield of secondary metabolites. The treatment procedure was done by cultivating the cells either with 100 ppm MNP, SMFs, or simultaneous exposure to both MNP and SMFs. The SMF at 30 mT was uniformly applied to the cells either for 3 or 4 days with a 3 h per day or a 5 h per day intervals, respectively. The contents of phenolics and phytochemicals were then examined by high performance liquid chromatography and UV-Vis spectrophotometer. These treatments imposed oxidative stress and induced polyphenol oxidase and phenylalanine ammonia lyase, accompanied by enhanced production of phenolics, anthocyanins, flavonoids, and lignin. The highest membrane embrittlement and elicitation was found upon simultaneous application of the MNPs and SMFs, followed by the MNP and SMFs. The contents of naringin, rosmarinic acid, quercetin, thymol, carvacrol, apigenin, and rutin increased in the intracellular biomass of all treated cells and extracellular culture media. These findings propose the potential of these elicitors in simultaneous production and secretion of these phytochemicals into culture media.

Abstract
Background: Determining the extent of seropositivity of SARS-CoV-2 antibody has the potential to guide prevention and control efforts. We aimed to determine the sero prevalence of SARS-CoV-2 antibody among adults in the general population of Diredawa, Ethiopia. Method: Community based cross-sectional survey was conducted among random sample of 648 adult population in Diredawa from June 15 to July 30, 2020 using interview and blood sample collection. Participants were asked about demographic characteristics, COVID-19 symptoms and adherence to preventive measures. Sero-prevalence was determined using SARS-CoV-2 IgG test.Result: The estimated SARS-CoV-2 prevalence was 3.2% (95 % CI: 2.0 - 4.8) in the study region with no differences by age and sex but considerable differences were observed by adherence to COVID-19 preventive recommendations. For instance, the prevalence of SARS-CoV-2 among participants who reported not to have practiced social distancing measures was 8.5 times the prevalence in their counterparts who reported of practicing social distancing. The corresponding estimates were 12.8 (95%CI, 7.0, 19) and 1.5 (95% CI, 0.5, 2.5) with statistically significant difference(p<0.01). Similarly, we observed 4.5 times higher prevalence among people who reported of not wearing face masks and who mentioned of not avoiding social gatherings. More than 80 percent of study participants reported of adherence to infection prevention measures (face masks and physical distancing recommendations). Conclusion: The SARS-CoV-2 sero-prevalence detected among adults in Diredawa was low and indicates much higher proportion of population not yet infected. COVID-19 preventive measures are associated with reduced prevalence and should be promoted to avoid transmission to the uninfected majority.

Abstract
Background: Current research shows that the anterior cable plays an essential role in rotator cuff tissue. To determine whether the distance between the supraspinatus central tendon and the long head of the biceps tendon, on a sagittal shoulder MRI scan, can predict anterior cable injury in rotator cuff tear patients before surgery. Method: A retrospective MRI scan was performed and a review of 103 patients with a rotator cuff tear – 50 patients with anterior cable injury and 53 patients without anterior cable injury. The distance between the supraspinatus central tendon and the biceps tendon’s long head was measured based on a sagittal MRI scan, and the tear size, degree of tear, and fatty degeneration of supraspinatus was also reviewed. SPSS software was used for statistical analysis of the relevant data. Two Independent Samples t-Test, binary logistics regression and receiver operating curve were also performed to evaluate select parameters.Results: The distance between the supraspinatus central tendon and the long head of the biceps tendon (DTD) was bigger in the anterior cable disrupted group (10.05±2.73 mm) when compared to the intact anterior cable group (7.96±2.30 mm) with a significant difference (P<0.01) Moreover, patients in the anterior cable disrupted group were of an older age, and there was a larger tear size and a worsened tear condition (P<0.05). Binary logistics regression t-Test showed that DTD is associated with anterior cable disruption. The receiver operating curve t-Test showed that DTD had an area under the curve of 75%. When setting the cut off value as 9 mm, DTD can predict anterior cable injury with a 74% sensitivity and 73.6% specificity. Conclusion: Compared with intact anterior cable patients, patients with anterior cable injury showed worsened tear condition and a larger distance between the supraspinatus central tendon and the long head of the biceps tendon, based on the oblique sagittal position of the MRI shoulder scan. Therefore, it may be a new tool for helping predict anterior rotator cable disruption in patients without obvious retraction.Trial registration: retrospectively registered
