Dynamic Enhanced Magnetic Resonance Imaging versus Ultrasonic Diffused Optical Tomography in Early Diagnosis of Breast Cancer

Objective To compare the application value of dynamic enhanced magnetic resonance imaging (MRI) and ultrasonic diffused optical tomography (DOT) in early diagnosis of breast cancer. Methods The clinical data of 110 female patients with breast diseases treated in our hospital from June 2018 to June 2021 were selected for the retrospective analysis, and the patients were divided into the benign lesion group (n = 50) and breast cancer group (n = 60) according to the pathologic findings. All patients received dynamic enhanced MRI and ultrasonic DOT examinations for the observation of lesion morphology and analysis of relevant parameters, so as to scientifically evaluate the diagnostic value of dynamic enhanced MRI and ultrasonic DOT for early breast cancer. Results The dynamic enhanced MRI examination found that the proportions of irregular shape, increased vascular shadow, obscure boundary, spicule sign, heterogeneous enhancement, etc. of lesion were significantly higher in the breast cancer group than in the benign lesion group (P < 0.05); parameters such as Ktrans, Kep, and Ve were significantly higher in the breast cancer group than in the benign lesion group (P < 0.05); the ultrasonic DOT diagnosis found that the THC value was obviously lower in the benign lesion group than in the breast cancer group (P < 0.05); compared with the pathologic findings, it was believed that combined diagnosis had significantly higher diagnosis accuracy rate, sensitivity, specificity, positive predictive value and negative predictive value than the dynamic enhanced MRI and ultrasonic DOT diagnosis alone (P < 0.05); and after further analyzing the efficacy of the two diagnosis modalities in diagnosing early breast cancer by ROC curves, the result showed combined diagnosis > dynamic enhanced MRI > ultrasonic DOT. Conclusion Both dynamic enhanced MRI and ultrasonic DOT present higher diagnostic value to early breast cancer, of which dynamic enhanced MRI obtains results closer to the pathologic findings and has diagnostic efficacy higher than ultrasonic DOT. But the combination of the two can significantly improve the diagnosis accuracy rate for early breast cancer, presenting higher diagnostic value.
Student Self Regulated Learning Strategy In Online Arabic Learning

This study aims to describe the self-regulated learning strategy of students of the Arabic Language Education Program at UIN Antasari Banjarmasin in online Arabic lectures during the pandemic. This study used a qualitative method with an exploratory investigative approach to identify 100 students' self-regulated learning strategies to support learning Arabic from a distance. This study examines 4 (four) indicators in self-regulated learning strategies, namely Goal Setting, Environment Structuring, Task Strategies, and Time Management. The results showed that one of the goal-setting strategies, where students hope to master the elements of Arabic and have Arabic language skills, got the highest average score of 5.68 out of 6. While the time management, in which students benefitted from online learning as it is flexible in determining additional study time, got the lowest average score of 3.95 out of a scale of 6. This value still shows a positive trend which can be interpreted that those students have carried out self-regulated learning strategies well in online Arabic lectures
COVID-19 Pandemic Increases the Impact of Low Back Pain: A Systematic Review and Metanalysis

In March 2019, the World Health Organization (WHO) recognized the COVID-19 pandemic as a global issue. To reduce the spread of this disease, health safety pathways were implemented worldwide. These extraordinary measures changed people’s lifestyles, e.g., by being forced to isolate, and in many cases, to work remotely from home. Low back pain (LBP), the most common cause of disability worldwide, is often a symptom of COVID-19. Moreover, it is often associated with different lifestyle features (type of job, physical activity, body weight). Therefore, the purpose of this systematic review and meta-analysis was to estimate the effect of the COVID-19 lockdown on LBP intensity and prevalence compared with LBP rates before the pandemic. A systematic search was performed on Scopus, PubMed, and Cochrane Central. Overall, eight studies with 2365 patients were included in the analysis. We used the Joanna Briggs Institute (JBI) critical appraisal tool to evaluate the risk of bias: six studies (75%) were at moderate risk of bias and two studies (25%) were at low risk of bias. These studies showed an increase in both the prevalence and intensity of LBP during the COVID-19 lockdown.
Development of Crash Modification Factors for Uncontrolled Pedestrian Crossing Treatments

The objective of this study was to develop crash modification factors for four treatment types: rectangular rapid-flashing beacon (RRFB), pedestrian hybrid beacon (PHB), pedestrian refuge island (RI), and advance yield or stop markings and signs (AS). From 14 cities throughout the United States, 975 treatment and comparison sites were selected. Most of the treatment sites were selected at intersections on urban, multilane streets, because these locations present a high risk for pedestrian crashes and are where countermeasures typically are needed most. For each treatment site, relevant data were collected on the treatment characteristics, traffic, geometric, and roadway variables, and the pedestrian crashes and other crash types that occurred at each site. Cross-sectional regression models and before–after empirical Bayesian analysis techniques were used to determine the crash effects of each treatment type. All four of the treatment types were found to be associated with reductions in pedestrian crash risk, compared with the reductions at untreated sites. PHBs were associated with the greatest reduction of pedestrian crash risk (55% reduction), followed by RRFBs (47% reduction), RIs (32% reduction), and AS (25% reduction). The results for RRFBs had their basis in a limited sample and must be used with caution.
Cervical Cancer Screening Uptake and Predictors Among Women in Jeddah, Saudi Arabia

Introduction: Cervical cancer is one of the most common cancers among females, contributing to significant mortality and morbidity worldwide. These numbers have significantly decreased since the implementation of cervical cancer screening. Despite that, screening in many countries, including Saudi Arabia, remains suboptimal. Methods: A cross-sectional study was conducted between May to November 2021 among 385 women aged 21-65 years who live in Jeddah, Saudi Arabia. The data were collected using a four-part online survey: demographic characteristics, cervical cancer screening status, predictors of undergoing cervical cancer screening, and barriers to screening. Results: Among the 385 women who completed the survey, only around one-third (33.4%) had a Pap smear at some point in their lives. The factors that were found to be significantly associated with the screening status (having a Pap test) in the univariate analysis are increasing age, education level, monthly income, perceived risk of getting cervical cancer, source of information about Pap test, having a family doctor, recommendation by the family doctor to have a Pap test, undergoing a gynecological examination, visiting a gynecologist in the past, history of previous gynecological complaint, and history of abortion. In the multivariable analysis, only four factors were found to be significantly associated with the screening status: age, monthly income, undergoing a gynecological examination in the past, and the recommendation by the family doctor, which by far had the largest effect. Conclusion: Cervical cancer screening rate is relatively low in the city of Jeddah. The recommendation of a Pap test by the family doctor had the largest impact on screening status. These results support the important role of family physicians in promoting screening tests for preventive healthcare. The results also suggest the need for education programs to promote cervical cancer screening among women in Saudi Arabia.
Impact of Channels Aspect Ratio on the Heat Transfer in Finned Heat Sinks with Tip Clearance

A 3D numerical study is used to analyze the flow topology and performance, in terms of heat transfer efficiency and required pumping power, of heat sink devices with different channel aspect-ratio in the presence of tip-clearance. Seven different channel aspect ratios AR, from 0.25 to 1.75, were analyzed. The flow Reynolds numbers Re, based on the average velocity evaluated in the device channels region, were in the range of 200 to 1000. Two different behaviors of the global Nusselt were obtained depending on the flow Reynolds number: for Re<600, the heat transfer increased with the channels aspect ratio, e.g., for Re=400, the global Nusselt number increased by 14% for configuration AR=1.75 when compared to configuration AR=0.25. For Re>600, the maximum Nusselt is obtained for the squared-channel configuration, and, for some configurations, flow destabilization to a unsteady regime appeared. For Re=700, Nusselt number reduced when compared with the squared-channel device, 11% and 2% for configurations with AR=0.25 and 1.75, respectively. Dimensionless pressure drop decreased with the aspect ratio for all cases. In the context of micro-devices, where the Reynolds number is small, these results indicate that the use of channels with high aspect-ratios is more beneficial, both in terms of thermal and dynamic efficiency.
Mobile Application Usability Evaluation: A Study Based on Demography

An application or product is considered "usable" if it is pleasing, easy to use, and works as expected user interface. Most companies majorly focus on the application’s functional requirements but put minimal effort into user experience (usability). Consumers’ adaptation of these applications depends on the number of features and user interface. In this work, an android based application, “Houzcalls” is used for usability study using PACMAD usability model. This work is focused on the variations in PACMAD attributes based on the participants’ education and age. Participants are segregated into two major groups FG1 and FG2 based on their education. All the participants with more than 10 years of education are in FG1 while others in FG2. Each focal group is divided into four subgroups Under 25, 25-35, 36-45, and Over 45 based on their ages. The results have shown participants in FG1 have shown more Effectiveness, Efficiency, Satisfaction, Learnability, and Memorability. In contrast, they have committed fewer Errors and shown less Cognitive Load during usability testing as compared to FG2. These variations can also be seen age-wise as generally “Under 25 and 25-35” subgroups have shown better results than other subgroups. It is inferred from the study that application usability and acceptability can be increased by considering the general population during development which includes all groups of people based on education and age.
Design of Ultra-Wideband Tapered Slot Antenna by Using Binomial Transformer with Corrugation

Abstract In this paper, the tapered slot antenna (TSA) with corrugation is proposed for UWB applications. The multi-section binomial transformer is used to design taper profile of the proposed TSA that does not involve using time consuming optimization. A step-by-step procedure for synthesis of the step impedance values related with step slot widths of taper profile is presented. The smooth taper can be achieved by fitting the smoothing curve to the entire step slot. The design of TSA based on this method yields results with a quite flat gain and wide impedance bandwidth covering UWB spectrum from 3.1 GHz to 10.6 GHz. To further improve the radiation characteristics, the corrugation is added on the both edges of the proposed TSA. The effects of different corrugation shapes on the improvement of antenna gain and front-to-back ratio (F-to-B ratio) are investigated. To demonstrate the validity of the design, the prototypes of TSA without and with corrugation are fabricated and measured. The results show good agreement between simulation and measurement.
COVID-19: The question of genetic diversity and therapeutic intervention approaches

Abstract Coronavirus disease 2019 (COVID-19), caused by the Severe Acute Respiratory Syndrome Coronavirus type 2 (SARS-CoV-2), is the largest pandemic in modern history with very high infection rates and considerable mortality. The disease, which emerged in China’s Wuhan province, had its first reported case on December 29, 2019, and spread rapidly worldwide. On March 11, 2020, the World Health Organization (WHO) declared the COVID-19 outbreak a pandemic and global health emergency. Since the outbreak, efforts to develop COVID-19 vaccines, engineer new drugs, and evaluate existing ones for drug repurposing have been intensively undertaken to find ways to control this pandemic. COVID-19 therapeutic strategies aim to impair molecular pathways involved in the virus entrance and replication or interfere in the patients’ overreaction and immunopathology. Moreover, nanotechnology could be an approach to boost the activity of new drugs. Several COVID-19 vaccine candidates have received emergency-use or full authorization in one or more countries, and others are being developed and tested. This review assesses the different strategies currently proposed to control COVID-19 and the issues or limitations imposed on some approaches by the human and viral genetic variability.
Seismic design and response of steel multi-tiered concentrically braced frames in Canada

This article investigates the seismic design and response of steel multi-tiered concentrically braced frames (MT-BFs) in which braces meet at columns between diaphragms. The seismic design provisions of CSA S16-14 are described and illustrated for three-tiered Type MD (moderately ductile) and five-tiered Type LD (limited ductile) braced frames. Analysis methods are proposed to evaluate the in-plane flexural demand on columns. The seismic response of the frames is examined through nonlinear response history analysis. As assumed in design, inelastic deformations tend to concentrate in one tier over the frame height, causing non-uniform drift demands and in-plane bending moments in the columns. CSA S16 provisions predicted well the frame in-plane flexural response and result in acceptable ductility demands on the braces. An extended seismic analysis and design approach that accounts for vertical distribution of brace tension yielding along the frame height is proposed for frames that exceed the limits prescr.
Individual differences in spontaneous facial expressions in people with visual impairment and blindness

People can visualize their spontaneous and voluntary emotions via facial expressions, which play a critical role in social interactions. However, less is known about mechanisms of spontaneous emotion expressions, especially in adults with visual impairment and blindness. Nineteen adults with visual impairment and blindness participated in interviews where the spontaneous facial expressions were observed and analyzed via the Facial Action Coding System (FACS). We found a set of Action Units, primarily engaged in expressing the spontaneous emotions, which were likely to be affected by participants’ different characteristics. The results of this study could serve as evidence to suggest that adults with visual impairment and blindness show individual differences in spontaneous facial expressions of emotions.
A Missile Jamming Design for Aircraft Defence Using Infrared Automated Counter Measures

: Infrared guided missiles possess a greater threat towards aircrafts in the scenario of defence. Securing aircrafts from such attacks requires an active directed infrared counter measure. Since DIRCM systems require the parameters of the missile signals to be known in advance, they suffer when attempted to be applied in real time. This paper proposes anInfrared Automated Counter Measures (IRACM) system with an equippedmissile alert equipment (MAE) capable of estimating the signal parameters once the signal is detected. Jamming is performed by which the missiles are subjected to miss the target along the field of vision by updating the jammer frequency based on the signal parameters. Since IR flashes in IRACM are emitted directly towards the missiles, it is considered more efficient when compared with the flare methods which emits in all directions. The experimental results of proposed method reveal that the system performs well in estimating missile signal parameters and the jamming effect is influenced by the estimated parameters.
Complete Duplex of the Left Ureter with Lower Moiety Hydronephrosis Secondary to Ureteral Stone in Adult

Ureteral duplication is a common embryologic abnormality of the kidney with an incidence rate of 0.8% in adults. However, complete duplex ureters opening independently into the urinary bladder are rarely present. We report a 35-year-old female who presented with left flank pain in the last three years. Abdominal CT scan showed left complete duplicated system with lower moiety hydroureteronephrosis and obstructed midureteral stone. The patient underwent left retroperitoneal exploration with complete excision of the hydronephrotic sac. The postoperative course was uneventful without complications. In conclusion, a complete duplex kidney with lower moiety hydronephrosis caused by mid ureteric stone is rare. The renal duplication system should be diagnosed and followed with image guidance periodically as the late diagnosis may have poor outcomes with loss of the kidney or part of it.
The endogenous progenitor response following traumatic brain injury: a target for cell therapy paradigms

Although there is ample evidence that central nervous system progenitor pools respond to traumatic brain injury, the reported effects are variable and likely contribute to both recovery as well as pathophysiology. Through a better understanding of the diverse progenitor populations in the adult brain and their niche-specific reactions to traumatic insult, treatments can be tailored to enhance the benefits and dampen the deleterious effects of this response. This review provides an overview of endogenous precursors, the associated effects on cognitive recovery, and the potential of exogenous cell therapeutics to modulate these endogenous repair mechanisms. Beyond the hippocampal dentate gyrus and subventricular zone of the lateral ventricles, more recently identified sites of adult neurogenesis, the meninges, as well as circumventricular organs, are also discussed as targets for endogenous repair. Importantly, this review highlights that progenitor proliferation alone is no longer a meaningful outcome and studies must strive to better characterize precursor spatial localization, transcriptional profile, morphology, and functional synaptic integration. With improved insight and a more targeted approach, the stimulation of endogenous neurogenesis remains a promising strategy for recovery following traumatic brain injury.
Effect of extracts from eggs of Helix aspersa maxima and Helix aspersa aspersa snails on Caco-2 colon cancer cells

Background Colorectal cancer is the third most commonly diagnosed cancer. Natural compounds, administered together with conventional chemotherapeutic agent(s) and/or radiotherapy, may be a novel element in the combination therapy of this cancer. Considering the anticancer properties of compounds derived from different tissues of various snail species confirmed earlier, the purpose of the present research was to evaluate the effect of extracts from eggs of Helix aspera maxima and Helix aspersa aspersa snails, and fractions of extracts containing particles of different molecular weights on Caco-2 human epithelial colorectal adenocarcinoma cells. Methods The extracts and fractions were analyzed for antioxidant activity, phenols and total carbohydrates using colorimetric methods. Lipid peroxidation products and glutathione in eggs were also examined using these methods. Crude protein and fat in eggs were determined. Molecular weights of egg proteins and glycoproteins were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Astaxanthin, selected vitamins and amino acids in eggs were measured using liquid chromatography methods, and minerals by emission spectroscopy, mass spectrometry or X-ray fluorescence. The action of extracts on the cell viability was determined by the MTT (methylthiazolyldiphenyl-tetrazolium bromide) test, based on the mitochondrial oxidative activity, after 24 and 72 h of treatment. The influence of fractions on the cell viability was assayed after 24 h. The effect of extracts on the percentage of live and dead cells was evaluated by the trypan blue assay, in which live cells exclude trypan blue, while dead cells take up this dye, after 12, 24, 48 and 72 h of treatment. Their influence on the integrity of cell membranes was determined based on the activity of LDH (lactate dehydrogenase), released from damaged cells, after 24 and 72 h of treatment. Then, the effect of extracts on the content of lipid peroxidation products in cells was examined using colorimetric method, after 24 h of treatment. Their influence on types of cell death was determined by flow cytometry, after this time. Results The extracts and their fractions containing molecules <3 kDa decreased the cell viability, after 24 h of treatment. The extracts reduced the percentage of live cells (also after 48 h), increased the degree of cell membrane damage and the amount of lipid peroxidation products, induced apoptosis and reduced necrosis. Conclusions Antioxidants, phenols, lipid peroxidation products, anticancer peptides, restriction of methionine, appropriate ratio of essential amino acids to non-essential amino acids, vitamin D3, Ca, Mg, S, Cu, Mn, Zn, Se and other bioactive compounds comprised in the extracts and their additive and synergistic effects may have influenced Caco-2 cells. Natural extracts or the chemical compounds contained in them might be used in the combination therapy of colorectal cancer, which requires further research.
