Comparative evaluation of marginal and internal fit of endocrowns using lithium disilicate and polyetheretherketone computer-aided design - computer-aided manufacturing (CAD-CAM) materials: An in vitro study

Purpose: To evaluate the marginal and internal fit of endocrowns with different computer-aided design/ computer-aided manufacturing (CAD-CAM) materials by measuring them with a stereomicroscope (μm). Materials and Methods: A mandibular first molar typodont tooth was prepared to receive an endocrown. The preparation was scanned using an extra-oral scanner. Endocrowns (n = 20) were fabricated using lithium disilicate (IPS e. max CAD LT block; CEREC Ivoclar Vivadent, Liechtenstein) and polyetheretherketone (PEEK) (breCAM. BioHPP®; Bredent, UK) using CAD-CAM technique. Marginal gap was evaluated using a stereomicroscope at the midpoint of all four surfaces (mid buccal, mid lingual, mid mesial, mid distal). This was followed by sectioning of the endocrowns in a sagittal plane along with the prepared tooth to evaluate the internal fit at four different points (A, B, C, D) using a stereomicroscope. Statistical analysis was performed using one-way analysis of variance test. Results: Mean values of marginal gap of lithium disilicate and PEEK endocrowns are 56.6 ± 6.1 μm and 81.3 ± 10.1 μm, respectively. Mean value internal gaps of lithium disilicate and PEEK endocrowns are 158.2 ± 11.1 μm and 199.1 ± 13 μm, respectively. Results in the present study have shown that the marginal and internal fits of lithium disilicate endocrowns are superior to that of PEEK endocrowns. Conclusions: Based on the outcomes of this in vitro study, the marginal and internal fit of lithium disilicate endocrowns is better than PEEK endocrowns. The marginal gap clinically acceptable is <120 μm. The marginal gap values recorded in this study are within the acceptable range for both materials.
A Study on the Emotional Intelligence among Teaching Faculty of a Medical College in South Karnataka

Introduction: Doctors have multiple roles to play in the society. The emotional intelligence (EI) of medical college teachers plays a decisive role on the outcome of medical students. Teachers with good EI will create a learning environment that encourages positive social interaction, active encouragement, and motivation to learn among students. Objectives: The objective of the study is to assess the level of EI and the influence of sociodemographic variables on it among teaching faculties of a medical college. Materials and Methods: A cross-sectional study was conducted using self-report EI questionnaire scale. The data were analyzed and expressed in percentages and proportions. Mean, standard deviation, and statistical significance were calculated, wherever necessary. Results: More than half of the teaching faculty showed average EI (66.67%) and 8.33% had poor EI. The social skills of teaching faculty showed positive correlation and statistical significance with teaching experience. Conclusion: There is a need to take appropriate steps to improve the EI of teaching faculties by the institutions as it has an impact on the outcome of learner doctors.
Determinants of Nutritional Status among Under-Five Children in the Tribal Population of The Nilgiris, Southern India: A Cross-Sectional Study

Background: The tribal populations in The Nilgiris of Tamil Nadu are identified as particularly vulnerable tribal groups (PVTGs) and are “high risk” in terms of health and nutrition. Objectives: The objective of the study is, among the under-five tribal children, to determine the prevalence of undernutrition and the factors associated with it. Materials and Methods: This community-based cross-sectional study was conducted between March and June 2019 among 605 under-five tribal children. The prevalence of underweight, stunting, and wasting was expressed as proportion; the association with determinants was assessed using log-binomial regression model. Results: The prevalence of underweight, stunting, and wasting was 63% (95% confidence interval [CI] 57–70), 62% (95% CI 54–70), and 31% (95% CI 24–38), respectively. Among them, 29%, 35%, and 10% were severely underweight, stunted, and wasted, respectively. Among 605 participants, 80% utilized supplementary nutrition program of the Integrated Child Development Services; only 21% of whom utilized it as per the ICDS recommended quantities prescribed for different category of beneficiaries. Male child, age >2 years, and illiteracy of father were significantly associated with underweight. Age >2 years and illiteracy of mother were significantly associated with stunting. Male child and low family income were significantly associated with wasting. Conclusion: Nearly three out of four children in the community were undernourished. Poverty alleviation programs are required to combat undernutrition among backward communities.
Underweight, Overweight, and Anemia among Elderly Persons in a rural area of Ballabgarh, Haryana

Background: Underweight, overweight, and anemia are common public health problems among elderly individuals. Objectives: The current study was conducted in a rural area of Ballabgarh, Haryana, to estimate the prevalence of underweight, overweight, and anemia among elderly persons and to find their association with sociodemographic variables. Materials and Methods: A total of 420 elderly persons aged ≥60 years were selected by simple random sampling. Information on variables was collected by an interview schedule. Body mass index (BMI) was calculated from height and arm-span of elderly persons. Hemoglobin was estimated with HemoCue® Hb 201+ system. Results: Of the total participants, 33.6% were underweight, 13.8% were overweight, 15.6% were obese, and 37.0% had normal BMI. None of the sociodemographic variables was found to be significantly associated with being underweight. Being female was significantly associated with being overweight/obese. The prevalence of anemia was 36.4%. None of the sociodemographic variables was associated with anemia. Conclusions: Underweight and anemia are common among elderly persons in rural areas. These need to be addressed through community-based interventions.
A Systematic Review on the Therapeutic Relevance of Hydroxychloroquine/Chloroquine in the Management of COVID-19

Background: The coronavirus disease-2019 (COVID-19) pandemic is coming to the fore and has surfaced as a public health emergency of international concern. The lack of vaccines or an effective treatment has led to the global hunt for potential pharmaceuticals in adequately managing this disease. This systematic review highlights the efficacy of chloroquine and its derivative hydroxychloroquine in the treatment of COVID-19 and also explores the safety profile of these drugs. Methods: EMBASE, COCHRANE, and PubMed databases were searched for studies on the use of hydroxychloroquine or chloroquine in the treatment of COVID-19. Results: Twenty articles were selected including expert opinions, National Guidelines, three small randomized controlled trials, and one prospective study. Both hydroxychloroquine and chloroquine have shown promising results including reduction in hospital length of stay and overall mortality. Moreover, concomitant use with azithromycin seems to reduce viral load to a greater extent. Conclusions: Considering the known safety profile of these drugs in the treatment of other diseases, their availability and affordability, chloroquine and hydroxychloroquine are potential antiviral agents in the treatment of COVID-19. However, reported side effects of these drugs when used in conjunction with azithromycin in patients with comorbidities have raised significant safety concerns. High-quality randomized clinical trials are warranted to provide more comprehensive evidence of the safety of these drugs in patients infected with COVID-19.
Selected macroeconomic determinants and economic growth in Cameroon (1970–2018) “dead or alive” an ARDL approach

PurposeThe purpose of this paper is to examine key macroeconomic determinants on Cameroon's economic growth from 1970 to 2018.Design/methodology/approachData were obtained from the World Development Indicators and applied on time series data econometric techniques. The auto-regressive distributed lag (ARDL) bounds model analyzed the data since the variables had different order of integration.FindingsThe results showed long and short runs’ positive and significant connection between economic growth in Cameroon and government expenditure; trade openness, gross capital formation and exchange rate. Human capital development, foreign aid, money supply, inflation and foreign direct investment negatively and significantly affected economic growth in the short and long-runs. Hence, the macroeconomic indicators are not death.Research limitations/implicationsThe present research paper has tried to capture the impact of nine macroeconomic determinants on economic growth such as the government expenditure (LNGOVEXP), human capital development (LNHCD), foreign aids (AID), trade openness (LNTOP), foreign direct investment (LNFDI), gross capital formation (INVEST), broad money (LNM2), official exchange rate (LNEXHRATE) and Inflation (LNINFLA). However, these variables have the tendency to affect each other in a unidirectional or bidirectional manner. Further, the present research paper is unable to capture the impact of other macroeconomic variable due to the unavailability of data.Practical implicationsThe study recommends that Cameroon should use proper planning and strategic policy interventions to achieve higher sustainable economic growth with human capital development, foreign aid, money supply, foreign direct investment and moderate inflation.Social implicationsMacroeconomic indicators, if managed well, increase economic growth.Originality/valueThis paper to the best of the researcher's knowledge presents new background information to both policymakers and researchers on the main macroeconomic determinants using econometric analysis.
Effect of CelliantVR armbands on grip strength in subjects with chronic wrist and elbow pain: randomized double-blind placebo-controlled trial

Purpose – This study aims to test the effects of Celliant armbands on grip strength in subjects with chronic wrist and elbow pain. CelliantVR is a functional textile fabric containing minerals that emit infrared radiation (IR) in response to body heat. IR-emitting fabrics have biological effects including the reduction of pain and inflammation and the stimulation of muscle function. Design/methodology/approach – A randomized placebo-controlled trial recruited 80 subjects (40 per group) with a six-month history of chronic wrist or elbow pain (carpal tunnel syndrome, epicondylitis or arthritis) to wear an armband (real Celliant or placebo fabric) on the affected wrist or elbow for two weeks. Grip strength wasmeasured by a dynamometer before and after the two-week study. Findings – For the placebo group, the mean grip strength increased from 47.956 25.14 (baseline) to 51.696 27.35 (final), whereas for the Celliant group, it increased from 46.36 22.02 to 54.16 25.97. The mean per cent increase over the two weeks wasþ7. 8% for placebo andþ16. 8% for Celliant (p= 0.0372). No adverse effects was observed. Research limitations/implications – Limitations include the wide variation in grip strength in the participants at baseline measurement, which meant that only the percentage increase between baseline and final measurements showed a significant difference. Moreover, no subjective measurements of pain or objective neurophysiology testes was done. Practical implications – Celliant armbands are easy to wear and have not been shown to produce any adverse effects. Therefore, there appears to be no barrier to prevent widespread uptake. Social implications – IR-emitting textiles have been studied for their beneficial effects, both in patients diagnosed with various disorders and also in healthy volunteers for health and wellness purposes. Although there are many types of textile technology that might be used to produce IR-emitting fabrics, including coating of the fabric with a printed layer of ceramic material, incorporating discs of mineral into the garment, © Ian L.

Cyclooxygenase-2 Expression and Effect of Celecoxib in Gastric Adenomas of Trefoil Factor 1-deficient Mice1

Expression of cyclooxygenase-2 (Cox-2) is elevated in gastric adenocarcinomas and precursor lesions leading to this disease. Mice deficient for trefoil factor 1 (TFF1) develop a pyloric adenoma with full penetrance. Because inhibition of Cox-2 suppresses tumor growth in several animal models, we studied expression of Cox-2 and effect of a selective Cox-2 inhibitor celecoxib in gastrointestinal tissues of the TFF1-deficient mice. Cox-2 mRNA and protein were strongly expressed in the pyloric adenomas of the TFF1 / mice as detected by in situ hybridization and immunohistochemistry. Nonneoplastic gastrointestinal tissues of wild-type or TFF1 / mice expressed low or nondetectable levels of Cox-2. Celecoxib (1600 ppm p.o. for 3 months) caused ulceration and inflammation of the adenoma in all treated TFF1 / mice (n 7). This effect of the drug was adenoma specific, because no histological alterations were observed in the non-neoplastic gastric or intestinal tissues in the TFF1 / or wild-type mice receiving the drug treatment. All untreated TFF1 / mice had an adenoma (n 7), but none demonstrated the combination of ulceration and inflammation. Our data show that Cox-2 is expressed in gastric adenomas of the TFF1 / mice and suggest that inhibition of Cox-2 disturbs the integrity of the adenoma by promoting ulceration and inflammation. These findings support the effort to initiate clinical studies to investigate the effect of Cox-2 inhibitors as a chemotherapeutic modality for dysplasias of the stomach.
Effects of Gibberellic Acid on Total Carbohydrate of Shoots, VegetativeGrowth and Flower Production in Barberry Plants

Background: The time of gibberellic acid application in the non-bearing year (OFF year) makes the different responses on seedless barberry plants in it (OFF year) and next year (ON year). Objective: The present research was conducted to evaluate the effects of gibberellin sprays applied at different times on barberry plants. Methods: The experiment was performed in three consecutive years (2016 to 2018) in Amirabad, Birjand, Iran. The treatments included: 1) Gibberellic acid (GA3 at 200 ppm), and 2) control (0 ppm), applied six times as foliar spraying on non-bearing trees, between April and September. The foliar sprays and measuring of vegetative traits were done on non-bearing trees in 2016 and 2017. Reproductive traits evaluated on bearing trees in 2017 and 2018. Results: Leaf number, width and length and internode length of current barberry shoots increased significantly. GA3 application significantly decreased by flower and fruit number, TSS/TA and anthocyanin content of fruit juice. Data showed that September might be a very important time for flower induction and differentiation. GA3 application increased the carbohydrate and phenol content of leaves and shoots. Conclusion: It can be concluded that spraying gibberellic acid influences all physiological and reproductive traits of barberry plants.
Food Texture Acceptance, Sensory Sensitivity, and Food Neophobia in Children and Their Parents

This study aims to explore whether children’s food texture preferences are associated with different levels of sensory sensitivity and food neophobia, as well as with other variables, such as parental texture preferences. An online questionnaire was completed by 70 children aged 6–13 years old, alongside one of their parents. Generic texture preferences of children and parents were investigated with the Child Food Texture Preference Questionnaire (CFTPQ). Parents provided background information about their children by completing the Food Neophobia Scale (FNS), the Short Sensory Profile (SSP) and a Food Frequency Questionnaire (FFQ). The results showed that children who differed in their texture-liker status also differed in their levels of food neophobia and sensory information processing: children who preferred softer and non-particulate versions of foods were found to be more neophobic and sensory sensitive across all sensory domains. No relationship was found between parental and children’s texture preferences.
Relatively Happy: The Role of the Positive-to-Negative Affect Ratio in Japanese and Belgian Couples

Satisfied couples in European-American cultural contexts experience higher ratios of positive to negative affect during interactions than their less satisfied counterparts. The current research tests the possibility that this finding is culture-bound. It compares proportions of positive to negative affect during couple interactions in two different cultural contexts: Belgium and Japan. Whereas Belgian relationship goals (e.g., mutual affirmation and self-esteem) call for the experience of positive affect, Japanese relationship goals (e.g., harmony and self-adjustment) call for the avoidance of negative affect. We propose that these differences result in different affect ratios in close relationships. To test this idea, we tracked positive and negative feelings during couple interactions. Fifty-eight Belgian and 80 Japanese romantic couples took part in a lab interaction study, in which they discussed a topic of disagreement. Using a video-mediated recall, participants rated their positive and negative feelings during the interaction; relationship satisfaction was assessed before the interaction. As expected, Belgian couples’ positive-to-negative affect ratios were more positive than those of Japanese couples. Furthermore, in both cultures relationship satisfaction was positively associated with more positive affect ratios, but this effect was significantly stronger for Belgian than Japanese couples. Finally, mediation analyses showed that higher affect ratios were achieved in culturally different and meaningful ways: satisfied Belgian couples showed higher ratios primarily through higher levels of positive feelings, whereas satisfied Japanese couples showed higher ratios primarily through lower levels of negative feelings.
Non-enzymatic degradation of carbon nanotubes in the presence of bacterial enzymes

The enzymatic degradation of carbon nanotubes (CNTs) by several enzymes has been reported. However, because organisms that possess these enzymes have limited habitats and distribution areas, it is unclear whether CNTs can be degraded in the general environment. The investigation of CNTs degradation by enzymes derived from bacteria, which inhabit a wide range of environments and have diverse metabolic systems, is inevitable for predicting the environmental fate of CNTs. In this study, the degradation of oxidized (carboxylated) single-walled CNTs (O-SWCNTs) by mt2DyP, a dye-decolorizing peroxidase of Pseudomonas putida mt-2, a common soil bacterium, was investigated. Suspensions of O-SWCNTs gradually became transparent and their optical absorbance decreased during 30 d of incubation in the presence of mt2DyP produced by a recombinant Brevibacillus choshinensis strain and its substrate, H2O2. The degradation was enhanced by higher H2O2 concentrations. The measurement of Raman spectra revealed the complete degradation of O-SWCNTs after 30 d of incubation with 100 mM H2O2. However, surprisingly, this heme enzyme was inactivated within 60 min of the incubation with O-SWCNTs, which suggested that the degradation of O-SWCNTs was not catalyzed by the enzyme. The inactivation of mt2DyP was accompanied by the release of iron, which suggested that the degradation of the O-SWCNTs was owing to the Fenton reaction caused by the iron released from mt2DyP and the supplied H2O2. A chelating agent, diethylenetriaminepentaacetic acid, significantly inhibited the O-SWCNTs degradation, proving the degradation by the Fenton reaction. These phenomena were also observed with another heme enzyme, Cytochrome P450. These results are important for predicting the fate of CNTs in a wide range of environments, as heme enzymes are secreted by many bacteria in the environment. This study also shows that the effect of the Fenton reaction should be considered to validate the degradation of CNTs by heme enzymes.
R AND C HAIN : A Scalable and Fair Decentralised Randomness Beacon

—We propose R AND C HAIN , a Decentralised Random-ness Beacon (DRB) that is the ﬁrst to achieve both scalability (i.e., a large number of participants can join) and fairness (i.e., each participant controls comparable power on deciding random outputs). Unlike existing DRBs where participants are collaborative , i.e., aggregating their local entropy into a single output, participants in R AND C HAIN are competitive , i.e., competing with each other to generate the next output. The competitive design reduces the communication complexity from at least O ( n 2 ) to O ( n ) without trusted party, breaking the scalability limit in existing DRBs. To build R AND C HAIN , we introduce Sequential Proof-of-Work (SeqPoW) , a cryptographic puzzle that takes a random and unpredictable number of sequential steps to solve. We implement R AND C HAIN and evaluate its performance on up to 1024 nodes, demonstrating its superiority (1.3 seconds per output with a constant bandwidth of 200KB/s per node) compared to state-of-the-art DRBs RandHerd (S&P’18) and HydRand (S&P’20).
nLORE: A Linguistically Rich Deep-Learning -Reference Extraction in

Location-based systems require rich geospatial data in emergency and crisis-related situations (e.g. earthquakes, floods, terrorist attacks, car accidents or pandemics) for the geolocation of not only a given incident but also the affected places and people in need of immediate help, which could potentially save lives and prevent further damage to urban or environmental areas. Given the sparsity of geotagged tweets, geospatial data must be obtained from the locative references mentioned in textual data such as tweets. In this context, we introduce nLORE (neural LOcative Reference Extractor), a deep-learning system that serves to detect locative references in English tweets by making use of the linguistic knowledge provided by LORE. nLORE, which captures fine-grained complex locative references of any type, outperforms not only LORE, but also well-known general-purpose or domain-specific off-the-shelf entity-recognizer systems, both qualitatively and quantitatively. However, LORE shows much better runtime efficiency, which is especially important in emergency-based and crisis-related scenarios that demand quick intervention to send first responders to affected areas and people. This highlights the often undervalued yet very important role of rule-based models in natural language processing for real-life and real-time scenarios.
