Can Students' Attitudes and Behaviors be Changed by Educational Interventions?
Authors: Gynnild Vidar , Tyssedal John Sølve 
Published: September 2021

This study examined engineering students’ attitudes and behaviors in a first-year Calculus course. Not surprisingly, High School mathematics and physics grades correlated closely with self-reported Calculus grades, and a student survey conducted four years apart demonstrated almost identical attitudes and behaviors despite the introduction of a range of measures aimed to enhance learning. The better the grades, the fairer students deemed it to be, and the less of in-depth learning, the poorer the grades. The higher the ambitions, and the more active and hardworking, the better the grades. Academic success factors included an ability to keep pace with progression, and a commitment to advance learning. The minimal impact of interventions appears as surprising; however, this study brings perspectives to make sense of such data, also capable of producing greater future successes.

Objective
The goal of this systematic review and meta-analysis is to determine the performance of 4% Articaine vs. 2% Lidocaine for mandibular and maxillary block and infiltration anaesthesia in patients with irreversible pulpitis (IP).

Methods
PubMed/MEDLINE, Cochrane Central Register of Controlled Trials, Web of Science, Google Scholar, and Open Gray were used to conduct a thorough literature search. A manual search of the reference lists of the publications found was also carried out. Two reviewers critically evaluated the papers for inclusion and exclusion criteria, and data extraction was done on the selected publications. The Cochrane Collaboration Tool and the Minors checklist were used to assess the quality of the selected studies for randomised controlled trials (RCTs) and non-randomised studies, respectively. The RevMan software was used to perform a meta-analysis of the pooled data and subgroups according to the technique of anaesthetic solution delivery, as well as a sensitivity analysis (P < 0.05).

Results
A total of twenty-six papers were included in the qualitative synthesis, with twenty-two of them being included in the meta-analysis. There were fifteen studies with a low potential for bias, three with a moderate potential for bias, and seven with a high potential for bias. The combined results of the 19 trials in the tooth level unit revealed that 4% articaine had a success rate 1.37 times greater than 2% lidocaine for mandibular teeth (RR, 1.37; 95% CI [1.17–1.62]; P = 0.0002). For the maxillary buccal infiltration method, the combined results from the three trials revealed that 4% articaine resulted in a success rate 1.06 times greater than 2% lidocaine (RR, 1.06; 95% CI [0.95–1.2]; P = 0.3). Excluding subgroups with a single study in sensitivity analysis for mandibular teeth revealed a substantial improvement in the success rate of the articaine group in treating IP when compared to the lidocaine group.

Conclusion
The findings of this meta-analysis back up the claim that articaine is more effective than lidocaine in providing anaesthesia in patients with IP. PROSPERO Registration No.: CRD42020204606 (https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020204606).

Published: September 2021

Aim: This study was designed to determine the bioethanol production from fermented cassava peel using Saccharomyces cerevisiae and Zymomonas mobilis.
Methodology: Cassava peels were collected from cassava processing sites, washed, surface sterilized, dried, milled into flour, pretreated, and fermented. Saccharomyces cerevisiae and Z. mobilis suspensions were aseptically inoculated into the fermenting medium and allowed to stand for seven days. The pH, total reducing sugar, chemical composition, and bioethanol composition of the fermenting substrates were determined.
Results: A pH decrease from 5.2 to 4.1 was recorded in the sample fermented with S. cerevisiae while the least pH value of 3.8 was obtained from the sample fermented with Z. mobilis, respectively. The total reducing sugar (glucose) of fermented samples decreased from 3.4% to 1.5% (Z. mobilis) and 3.4% to 1.88% (S. cerevisiae) compared with the control sample. The chemical composition showed high protein and fat contents in the fermented samples. High percentage yield of 30% with ethanol volume of 45 mL was recovered from cassava peel inoculated with S. cerevisiae while flash point, i.e. the lowest temperature at which fuel produces enough vapor to cause ignition leading to flame generation of 24oC, was recorded for both fermented samples inoculated with S. cerevisiae and Z. mobilis.
Conclusion: The ability of the bacterium and the yeast isolates exhibiting high potential for bioethanol production could be promising in various industrial processes as an alternative to fossil transportation fuel.

Aim: The present research work was carried out to formulate stable fixed dose combination tablets of Bilastine and Montelukast Sodium, used to treat allergic rhinitis associated with asthma and rhino-conjunctivitis on basis of pre and post post-compression parameters evaluation and drug-drug-excipients compatibility studies.
Methods: Direct compression methodology was used for tablet production and final composition of drugs and excipients was optimized by evaluating pre and post compression evaluations of blend and tablets respectively. The chemical instability and stability studies were carried out using HPLC method.
Results: The Evaluation of pre-compression parameters of batch F1 to F5 shows that as we increase the amount of sodium starch glycolate and colloidal silicon dioxide from F1 to F5, bulk density and tapped density increases slightly whereas the compressibility index and hausner’s ratio of tablets was shifted from excellent to good. Angle of repose shows excellent flow property from F3-F5. After evaluation of post-compression parameters from F1 to F5, there is no significant difference in diameter, thickness and average weight of tablets. The hardness of tablets was decreased slightly from F1 to F5 therefore, the % friability was found to be increased from F1 to F5 and disintegration time was found to be decreased from F1 to F5. Dissolution studies shows % release of Bilastine and Montelukast was increased towards F1 to F5 as the percentage of Sodium Starch Glycolate increases. The drug-drug-excipients compatibility shows that there is no physical and chemical incompatibility between the drug-drug-excipients at accelerated conditions. The stability studies show that % assay of long term and accelerated samples are within 100±2%.
Conclusion: The optimized composition found in order to scale up the production of tablets.
Expression of ITG β-1, MMP9 and Vimentin in Oral Squamous Cell Carcinoma – A Real Time PCR Based Approach
Authors: Umashankar Krishnapriya , Selvaraj J. , Ramani Pratibha 
Published: September 2021

Background: Oral Squamous Cell Carcinoma (OSCC) is the most common malignancies which accounts for 90% of oral cancer worldwide. The 5 year survival rate of OSCC is not more than 60% due to tumor metastasis and subsequent recurrence.
Aim: To compare the gene expression of ITG β-1, MMP9 and Vimentin in OSCC tissue samples and normal tissue samples and to correlate the expression levels of these molecules with the pathological grading and survival in OSCC patients. This would facilitate the understanding of EMT in OSCC progression thereby targeting this pathway for treatment of OSCC patients in near future.
Materials and Methods: 10 OSCC samples as well as normal healthy samples were collected and RNA isolation was done using TRIR kit, and then subjected to cDNA synthesis using ITG β-1, MMP9 and Vimentin primers. Real time PCR was performed using gene specific primers at 40 cycles. The results were retrieved, tabulated and analyzed.
Results: The current research results revealed that there were up regulation of mRNA expression in ITG β-1, MMP9 and Vimentin in OSCC patients than in healthy individuals. On comparison, MMP9 showed highest mRNA expression levels than ITG β-1 and Vimentin
Conclusion: Over expression of ITG B-1, MMP9, Vimentin plays a crucial role in progression of oral cancer and targeting EMT molecules could be an effective targeted approach for OSCC.
The “Silent Teacher”: Learning by teaching via writing a verbatim teaching script
Authors: Lim Kagen Y. L. , Wong Sarah Shi Hui , Lim Stephen Wee Hun 
Published: September 2021

AbstractLearning by teaching others is a potent educational strategy, but its implementation is typically cumbersome. This study (N = 108) investigated “silent teaching”—writing a verbatim teaching script—as a convenient approach for independent learning, while assessing whether the teaching benefit is a production benefit. Learners studied a science text on the Doppler effect using one of three learning methods: (1) generating and studying their own notes (restudying control), (2) preparing to teach and then verbally teaching (verbal teaching), or (3) preparing to teach and then writing a verbatim teaching script (silent teaching). On a conceptual knowledge retention test 1 week later, participants who wrote teaching scripts performed as well as those who taught verbally; both teaching groups outperformed control learners. Verbal and silent teaching significantly increased social presence and elaboration to comparable extents, relative to restudying. “Silent teaching” is a promising and efficient alternative learning approach to traditional verbal teaching.

Published: September 2021

ObjectivePatients with cancer and systemic lupus erythematosus (SLE) may have worse outcomes than those without SLE, given their comorbidities. We examined survival in elderly women with breast cancer (BC) and SLE and hypothesized that survival would be decreased compared with women with BC but without SLE.MethodsWe identified patients with BC and SLE and patients with BC without SLE in the Texas Cancer Registry and Surveillance, Epidemiology, and End Results, linked to Medicare claims. Overall survival (OS) was estimated after matching (age and cancer stage) and in multivariable Cox proportional hazards models adjusting for other cancer characteristics, treatment, and comorbidities. Two additional cohorts of women without cancer with and without SLE were also studied.ResultsWe identified 494 BC SLE cases and 145,517 BC non‐SLE cases, of whom we matched 9,708. Women with SLE were less likely to receive radiation, breast conserving surgery, or endocrine therapy. The 8‐year OS estimate for women with early BC (stages 0–II) with and without SLE was 52% (95% confidence interval [95% CI] 45%–59%) and 74% (95% CI 73%–75%), respectively. In the Cox multivariable model, BC and SLE had increased risk of death (hazard ratio [HR] 1.65, 95% CI 1.38–1.98). Women with BC and SLE also had increased risk of death compared with women with SLE but without cancer (HR 1.42, 95% CI 1.05–1.92) after adjusting for SLE severity. Women with SLE and BC received less glucocorticoids, antimalarials, and immunosuppressants after cancer diagnosis than those without cancer.ConclusionSystemic lupus is a risk factor for increased mortality in women with early BC.
Dynamic optimal operational control for complex systems with uncertain external loop disturbances
Authors: Yin Liping , Xu Yangbo , Chen Xin , Li Tao 
Published: September 2021

AbstractIn this article, a two‐layer control strategy is proposed for industrial processes where loop controllers are difficult to change. The upper layer performs the determination of the target value and the dynamic adjustment of the set points, while the lower layer realizes the tracking control of loop outputs. To optimize the performance index, observers are designed to estimate those uncertain external disturbances and a new set points adjuster is designed to minimize the influence of disturbances on the overall performance. It is noted that neither the loop structure nor the loop parameters are changed in the operational control. Finally, a simulation on coke oven gas system is given to demonstrate the effectiveness of this method.

Published: September 2021

AbstractAssessment of glucose concentration is important in the diagnosis and treatment of diabetes. Since the introduction of enzymatic glucose biosensors, scientific and technological advances in nanomaterials have led to the development of new generations of glucose sensors. This field has witnessed major developments over the last decade, as the novel nanomaterials are capable of efficiently catalyzing glucose directly (i.e., act as artificial enzymes, therefore defined nanozymes) or to entrap enzymes that are able to oxidize glucose. Among other nanomaterials, metal–organic frameworks (MOFs) have recently provided a tremendous basis to construct glucose sensing devices. MOFs are large porous crystalline compounds with versatile structural and tuneable chemical properties. In addition, they possess catalytic, peroxidase‐like, and electrochemical redox activity. This review comprehensively summarizes the general characteristics of MOFs, their subtypes, and MOF composites, as well as MOF‐derived materials employed to construct electrochemical, optical, transistor, and microfluidic devices for the detection of glucose. They include enzymatic, nonenzymatic, wearable, and flexible sensing devices and methods. The review also outlines the design and synthesis of MOFs and the working principles of the different transduction‐based glucose sensors and highlights the current challenges and future perspectives.

Published: September 2021

AbstractCancer remains an intractable medical problem. Rapid diagnosis and identification of cancer are critical to differentiate it from nonmalignant diseases. High‐throughput biofluid metabolic analysis has potential for cancer diagnosis. Nevertheless, the present metabolite analysis method does not meet the demand for high‐throughput screening of diseases. Herein, a high‐throughput, cost‐effective, and noninvasive urine metabolic profiling method based on TiO2/MXene‐assisted laser desorption/ionization mass spectrometry (LDI‐MS) is presented for the efficient screening of bladder cancer (BC) and nonmalignant urinary disease. Combined with machine learning, TiO2/MXene‐assisted LDI‐MS enables high diagnostic accuracy (96.8%) for the classification of patient groups (including 47 BC and 46 ureteral calculus (UC) patients) from healthy controls (113 cases). In addition, BC patients can also be identified from noncancerous UC individuals with an accuracy of 88.3% in the independent test cohort. Furthermore, metabolite variations between BC and UC individuals are investigated based on relative quantification, and related pathways are also discussed. These results suggest that this method, based on urine metabolic patterns, provides a potential tool for rapidly distinguishing urinary diseases and it may pave the way for precision medicine.

AbstractThe Josephson plasmon resonance (JPR) offers a valuable probe to investigate the superconductivity in layered cuprate superconductors. However, the coupling between free space radiation and JPR in high‐temperature superconductor (HTS) film remains challenging because the excitation of JPR demands the c‐axis oriented electric field. The subwavelength resonators in metamaterials can enhance the localized electric field, which can be utilized to resolve this difficulty. Here, a tunable terahertz (THz) metamaterial made from Tl2Ba2CaCu2O8 (Tl‐2212) HTS film is developed. The spectral response of Tl‐2212 metamaterial has a tunable property at temperatures up to 90 K. The resonant excitation of Josephson plasmon in the metamaterial is observed. Simulation results indicate that the scattering of subwavelength resonators can provide the component of the z‐axis electric field for the resonant excitation. The coupling between JPR and resonance modes of metamaterials is observed and explained using coupled mode theory. The temperature dependence of JPR frequency shows accordance with the experimental results of the pure film. This work provides an avenue to excite the JPR and probe superconducting condensate in the layered superconductor. The development of Josephson plasmonic metamaterials may contribute to tunable and nonlinear THz devices.
