Biochemical markers in saliva in patients with oral cancer

Head and neck cancers account for 3% of all human cancers and are mainly localized in the oral cavity. Early detection of cancer is extremely important for reducing mortality and morbidity from this disease. In addition to clinical trials and histopathological findings, in the last two decades, with technological development, more specific and sensitive methods have been used in the analysis of salivary markers. The aim of this study was to present a wide range of analyzed markers in saliva: different protein markers (total proteins, albumin, defensins, staterin, cystatins), epithelial and molecular markers (CA125, CA19-9, TPA, CEA, CYFRA 21-1, CD44), enzymes (LDH, ALP, MMP, SOD), cytokines (IL-6, IL-8, IL-1? , TNF-? ), oxidative stress markers (8-OHdG, MDA), non-enzymatic antioxidants (glutathione, uric acid, albumin, vitamin C and E) etc. Collecting saliva is simple and painless for the patient, it does not require expensive equipment or specially trained staff, and it is possible to take saliva several times and in unlimited quantities. Extensive research that is increasingly being done with modern techniques indicates that saliva may be useful for early detection of the disease in the near future.
Target BP Goals in Children/Adolescents

Childhood hypertension (HTN), increasingly being detected and being prevalent, has become a significant public health problem not only posing a therapeutic challenge but also being associated with increased fatality and morbidity. Cutoffs for different age groups for the diagnosis, difficulties with accurate measurements in childhood, poor adherence to medication due to dependency, and absence of enough evidences for target organ damage of this disease, which is less prevalent in children when compared to adults, makes monitoring of HTN and of its associated morbidities more complicated in pediatric population. Predisposition to adult HTN and increased cardiovascular events in adults mandate the clinician to treat and monitor the childhood HTN more aggressively. [1-2]
Growth of Polyelectrolyte Layers Formed by Poly(4-styrenesulfonate sodium salt) and Two Different Polycations: New Insights from Study of Adsorption Kinetics

We report an experimental study on the growth and adsorption kinetics of polyelectrolyte multilayers (PEMs). PEMs composed of poly(diallyldimethyl ammonium chloride) (PDADMAC) and poly(sodium 4-styrenesulfonate) (PSS), and of poly(allylamine hydrochloride) (PAH) and PSS polyelectrolyte pairs were built and studied via dissipative quartz crystal microbalance (D-QCM) and ellipsometry. The results have pointed out that the growth trend of PEMs may be controlled by the assembly conditions that modify the layer structure and subsequently the film features. The study of adsorption kinetics of the layers suggests that, even though interdiffusion may take place during the growth of PEMs, it does not determine the growth mechanism. Analysis of the mechanical properties allows confirmation of the scenario proposed for the explanation of the PEMs growth. Independent of growth type, the adsorption kinetics of the layers is a bimodal process. The results here presented allow us to rule out any correlation between grow.

Retrieving Wave Parameters From GNSS Buoy Measurements Using the PPP Mode

Global Navigation Satellite System (GNSS) buoys were used to retrieve the significant wave heights (SWHs) and dominant periods of waves in the Qingdao coastal waters off China. The precise point positioning (PPP) and postprocessed kinematic (PPK) techniques were used to obtain the absolute motion of the GNSS buoys. Even though PPP has relatively low absolute positioning accuracy, this accuracy has a minimal influence on the spectrum in the wave frequency band. SWH values calculated from the PPK and PPP modes are nearly identical, with correlation coefficients and symmetric regression slopes both higher than 0.99. The SWH values calculated from PPP also show good agreement with a dedicated wave buoy, with a correlation coefficient of 0.935 and a difference of 0.82 cm ± 4.63 cm. A GaoFen-1 satellite image was used to assess the GNSS PPP wave spectrum via the dispersion relationship; both exhibit wave spectra with two peaks, consistent with the wave characteristics in the area.
Improved radioanalytical method for the simultaneous determination of Th, U, Np, Pu and Am(Cm) on a single TRU column by alpha spectrometry and ICP-MS

Abstract A radioanalytical method based on the use of a single TRU extraction chromatographic column and selective, on-column oxidation state adjustment of actinides was developed for the determination of Th, U, Np, Pu and Am(Cm) in environmental samples (such as sediment and swipe samples). The procedure of Vajda et al. [1] was further investigated and optimized focusing on the separation of Th, U and Np. The improved method combines two measurement techniques — alpha spectrometry and inductively coupled plasma mass spectrometry (ICP-MS) – which allows to obtain more reliable information on a wider range of isotopes: 228Th, 230Th, 232Th, 234U, 235U, (236U), 238U, 237Np, 238Pu, 239Pu, 240Pu, 241Pu, 241Am, 242Cm, 243Cm and 244Cm from one sample.
PERFORMANCE ANALYSIS OF THE ORÁCULO FRAMEWORK FOR DATA COLLECTION FROM TWITTER / ANÁLISE DO DESEMPENHO DO FRAMEWORK ORÁCULO PARA COLETAS NO TWITTER

Online social networks are important social spaces for human interaction, with far-reaching applications in communication, entertainment, advertising, social campaigning and community empowerment. Shared data have become a research source for several studies seeking to analyze user interactions in these networks. Because of the large volume of data produced, text mining techniques are required for analyzing the collected data efficiently. One of the challenges of the text mining process is the lack of direct access to data from online social networks, which requires the use of specialized tools for collecting data. The present study conducts a performance analysis of Oráculo Application Development Framework as a tool for collecting and mining texts shared on the social network Twitter. In this framework, different algorithms and techniques were applied to circumvent the limitations imposed by the Twitter API. Performance tests were conducted comparing the Oráculo and DMI-TCAT algorithms. The results show that Oráculo presents superior performance in the number of tweets collected compared to DMI-TCAT considering the algorithms and scenarios analyzed.

A quantidade total de ouro presente no processador foi determinada apos digestao total da amostra com solucao de agua regia. Nas condicoes estudadas, o tempo de 30 minutos de lixiviacao apresentou a maior quantidade de ouro extraido, cerca de 45%.
Rebuilding a Shattered Reputation: Financial Reporting Quality and Donations Following Corporate Controversies

We examine the consequences of controversies on corporate reputation and identify two reputation-building strategies that companies are adopting to restore their trust relationships with stakeholders in the aftermath of media condemnation. In particular, we find that in the post-controversy period, firms take a bolstering strategy of reducing their discretionary accruals and endeavour to restore their reputation by engaging more actively in philanthropic activities. Such behaviour coheres with the image repair theory propounded by (Benoit, 1995). While boosting financial reporting quality proves marginally more efficacious than charitable giving, our findings indicate that reputation is easily tarnished, but difficult to rebuild.
Exploring affective barriers in virtual exchange: the telecollaborative foreign language anxiety scale

The technological revolution of Information and Communication Technology (ICT) has brought about new learning scenarios as well as new professional requirements, such as the development of intercultural and Foreign Language (FL) skills. In this regard, Virtual Exchange (VE) projects provide students with learning opportunities through online social interaction and collaboration (Dooly, 2017); allowing authentic intercultural experiences for students who do not have the opportunity of travelling (O’Dowd, 2016) and promoting 21st-century skills development (Jager, Kurek, & O’Rourke, 2016). However, interacting online in the FL with a person from a different culture can entail an affective challenge for students and might give rise to Foreign Language Anxiety (FLA). FLA is a dysphoric and situational anxiety suffered by one out of three FL students which inhibits communication and learning (Horwitz, Horwitz, & Cope, 1986). Due to the impossibility of finding an available tool to investigate the presence and effects of FLA in VE environments, the Telecollaborative FLA Scale (T-FLAS) was designed. This article presents the development of the T-FLAS, a 21-item questionnaire with a five-point Likert scale, aiming to provide researchers and practitioners with a tool to explore FLA in VE.
End-Capping Effect of Quinoxalino[2,3-b′]porphyrin on Donor–Acceptor Copolymer and Improved Performance of Polymer Solar Cells

A series of end-capped donor–acceptor copolymers, P(BT-DPP)-T, P(BT-DPP)-QP, and P(BT-DPP)-QPZn, were synthesized by Stille coupling of 2,2′-bithiophene (BT) and diketopyrrolopyrrole (DPP) with end-caps of thiophene (T), quinoxalino[2,3-b′]porphyrin (QP), and quinoxalino[2,3-b′]porphyrinatozinc (QPZn), respectively. Compared with the counterpart, P(BT-DPP), which contains no end-caps, P(BT-DPP)-QP and P(BT-DPP)-QPZn showed remarkably enhancement of light absorption in the range of ca. 400–550 nm resulted from the end-capping effect of porphyrins. Bulk heterojunction polymer solar cells (PSCs) based on these polymers were fabricated and the results showed significant improvement of power conversion efficiencies (PCEs) of the end-capped polymers. Especially, ligand addivie, 4,4′-bipyridine (Bipy), was applied to the PSCs based on polymers end-capped by porphyrins and the PCE of the photovoltaic device based on P(BT-DPP)-QPZn significantly improved from 2.92% to 4.45% with the comprehensive benefits of optim.
OPTIMIZATION OF THE ELECTRO-FENTON PROCESS FOR COD REDUCTION FROM REFINERY WASTEWATER

This study shows the results of the experimental investigation of refinery wastewater treatment by the electro-Fenton process. The experiments were designed using Taguchi design approach with an orthogonal array (OA) of L16 runs. Four process variables (current density (CD), temperature (T), Fe2+ concentration (Fe2+), and time (t)) at four different levels were considered for the present design. Regression analysis was performed to predict a correlation for the response function (chemical oxygen demand (COD) reduction efficiency) of the treatment process by the electro-Fenton technique. Analysis of variance (ANOVA) was carried out to verify the significant variables that control COD reduction. Moreover, a linear model analysis was implemented for the signal to noise (S/N) ratios with "larger the better" and for means. Based on S/N ratios and means responses, the operating conditions for optimum COD reduction were: CD = 8 mA/cm2, T = 60°C, Fe2+ = 0.4 mM, and t = 6 h, at which 87.35% of COD was reduced. ANOVA shows that the operating temperature had the most significant impact on COD reduction efficiency. The R-square value for the predicted COD reduction correlation was 90.00%. Considering ranks based on delta statistics, the relative magnitude of effects of the process variables were: T, Fe2+, t, and CD.
An in Vitro Comparison of Coronal Discolouration Caused by White Mineral Trioxide Aggregate, Theracal, Calcium-Enriched Mixture and Biodentine

Objective: The use of calcium silicate-based cements has greatly increased in the past decade. This study compared coronal discolouration caused by white mineral trioxide aggregate (MTA), TheraCal (TC), calcium enriched mixture (CEM), and Biodentine (BD) on bovine enamel-dentin block. Methods: In this in vitro, experimental study, enamel-dentin blocks (7x7x3.5 mm) were cut out of 60 extracted sound bovine central incisors. A cavity (2.5 mm diameter and 1 mm depth) was created at the center of each block with 1 mm distance from the labial surface. The blocks were randomly divided into four experimental groups (n=12) of MTA, CEM, BD, and TC and two groups of positive (blood) and negative (empty) controls. After filling cavities with experimental materials, the surfaces of the materials were covered with composite resin. The colour parameters were measured using a spectrophotometer, before (T0) and 1 week (T1), 1 month (T2), and 6 months (T3) after the application of the materials. The data was analysed using repeated measures ANOVA and the Kruskal-Wallis test. Results: At 1 week and 1 month, a significant difference in ∆E was noted in the control groups compared to the experimental groups (P<0.001). The difference among the four cements was not significant (P=0.06) at 1 week but it was significant at 1 month. TC showed greater ∆E whereas BD showed lower ∆E in the six-month period (P<0.001). Colour change was significant over time in the MTA and TC groups (P<0.05). Conclusion: TheraCal caused greater discolouration in the bovine tooth blocks after 6 months, which may make it inappropriate for application in the aesthetic zone.

Psychosocial, and Socio-Economic Crisis in Bangladesh due to COVID-19 Pandemic: A Perception-Based Assessment

The COVID-19 pandemic situation, disease intensity, weak healthcare facilities, unawareness, and misinformation led people to fear and anxiety in Bangladesh. This study intended to get peoples’ perception on psychosocial, socio-economic and environmental crisis amidst the pandemi. An online questionnaire was surveyed nationwide (respondents no.1066). Datasets were analyzed through the Principal Component Analysis (PCA), hierarchical Cluster Analysis (CA), Pearson’s correlation matrix (PCM), Linear regression analysis (LRA), and psychometric characteristics were included in the Classical Test Theory (CTT) analysis. There were good associations among the psychosocial, socio-economic and environmental parameters. A significant association between fear of COVID-19 with struggling healthcare system (p<0.05) was found. Also, negative association between fragile health system and government’s ability to deal with the pandemic (p<0.05) revealing poor governance. Again, a positive association of shutdown and social distancing with fear of losing life, and due to lack of health treatment (p<0.05) reveals that shut down hampers normal activities which may lead to mental and economic stress. However, a positive association of socio-economic impact of the shutdown with poor people’s suffering, the price hike of basic need, hamper of formal education (p<0.05) may lead to severe socio-economic and health crisis. There is a possibility of climate-induced disaster during/after the pandemic, which will create severe food insecurity (p<0.01). Daily wage earners and poors will suffer most by food and nutritional deficiency, and the country may face huge economic burden. Proper risk assessment and communications is needed to alleviate fear and anxiety. Thus, financial support and mental boosting is required.
Prognostic Value of Charlton’s Weighted Index of Capabilities Combined with Chronic Health Evaluation II Score in COVID-19：a retrospective cohort study

Background: Since December 2019, coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread across the world. Age and underlying diseases have been reported as predictors of mortality in 2019-nCoV infection. Charlson's weighted index of comorbidities (WIC) and acute physiology and chronic health evaluation (APACHE) II are two frequently-used measures of comorbidity. In this study, we have assessed the performance of WIC and APACHE II in predicting the mortality of COVID-19 patients.Methods: A total of 76 adult patients with COVID-19 were admitted to a designated hospital in Huangshi province from 1 January 2020 to 29 February 2020. Clinical data including age, gender, underlying diseases, and hospital mortality were collected. The APACHE II and WIC scores were assessed within the first 24 hours of admission. Univariate and multiple logistic regression analyses were used to compare the performance of WIC, APACHE II, and joint detection. The area under the receiver operating characteristic curve (AUC) was used to predict the hospital mortality. Results: Of the 76 enrolled patients, 57 patients survived, and 19 died. The surviving patients had significantly lower WIC and APACHE II than the non-surviving patients (p-value < 0.05). The AUC for the hospital mortality was 0.814 (95% confidence interval (CI) 0.705-0.923) of WIC, 0.854 (95% CI 0.705-0.956) of APACHE II and 0.891(95% CI 0.830-0.966) for the joint detection. The diagnostic value of the joint detection was found to be better than that of WIC (p-value= 0.002) or APACHE II (p-value = 0.042). Conclusions: The WIC and APACHE II scores might serve as independent determinants for the hospital mortality associated with COVID-19 patients. The combined use of WIC and APACHE II is more predictive than individuals．
System Fertilization: a Viable Practice for Black Oat-soybean Crop

: System fertilization is characterized by partial or total fertilizer application at the predecessor crop; and it can be a viable practice to soybean crop. This study aimed to determine the fertilizer management and fertilizer levels for black oat-soybean cropping system, in high fertility soils and no-tillage system. The field trial was conducted in a bifactorial scheme, consisting of six environments, by combination of locations (Bom Sucesso do Sul - Paraná, Itapejara d'Oeste - Paraná) and fertilization management (all fertilization in black oat; splitting with 50% in black oat and 50% in soybean, all fertilization in soybean), and four fertilizer levels (0, 100, 200 and 300%) defined according to soil analysis and production expected. The evaluated traits were dry mass production, N, P and K nutrient accumulation of straw, dry mass remaining of black oat crop; and plant height, number of pods per plant, thousand grain weight, grain yield for soybean crop. Higher black oat dry mass production was observed at higher fertilization level. The fertilizer anticipation in black oat crop had better performance. Phosphorus and potassium accumulation increased linearly with fertilizer level increase. For N, the highest accumulated value occurred at the 200%, decreasing at the 300% of fertilizer level. The soybean crop had no influence in grain yield considering fertilization management, anticipation or splitting, and fertilizer levels. Thus, the system fertilization can be a viable practice, and favor black oat dry mass production and soybean development.
Intermittent versus daily dosing of meropenem in haemodialysis patients – A retrospective observational exploratory study

BackgroundExtended microbial resistance is very common in patients on haemodialysis, often needing long courses of carbapenems. This results in increased length of stay in hospital and its complications. However, carbapenems can be given intermittently and avoid this problem.We aim to describe the clinical outcomes of intermittent versus daily meropenem in thrice weekly haemodialysed patients.Methods: 125 records were examined retrospectively. Data collected includes patient demographics, clinical interventions such as source control, meropenem dose and regime, and clinical outcomes such as length of hospital stay (LOS), 30-day readmission rates and adverse events.Results: Mean age was 62.6±1.3 years, 56% were male. 65.6% were on haemodialysis secondary to diabetic nephropathy, and 84% were on thrice-weekly regime. Most common bacteria cultured was Klebsiella pneumoniae (14.4%), the most common indication for meropenem was pneumonia (32%) and mainly used for cure (65%). Mean duration of therapy on meropenem was 11.5±1.2 days, 8 patients needed more than 30 days of meropenem. 59.2% did not have intervention for source control.87. 2% received daily dosing of meropenem. 6.4% patients received intermittent dosing of meropenem only, 4.8% patients received both types of dosing regimens. Dosing was variable across both arms.LOS of the index admission was shorter for the intermittent arm, 15.5±2.7 days compared to daily arm, 34.7±2.7 days. Though 30-day readmission was higher (50% in the intermittent arm versus 33.1%), total LOS in the year was still lower (49±18.0 days in the intermittent arm versus 53.3±14.9 days). There were few adverse events in both arms.Conclusion: Our study suggests that intermittent dosing of meropenem may be helpful for reducing hospital length of stay. We suggest for randomised controlled trials to prove its safety and efficacy.
