Myocardial Infarction in a Young Female Patient with Subtotal Occlusion of the Mid OM Branch: A Case Report and Review of Potential Causes
Authors: Menon Tushar
Published: June 2023

Chest pain is a common presenting symptom in emergency departments, and its evaluation and management require careful consideration of various potential causes, ranging from benign musculoskeletal pain to serious cardiac conditions. Myocardial infarction (MI) is a well-known cause of chest pain, particularly in older individuals with risk factors such as hypertension, hyperlipidemia, and smoking history. However, MI in young patients without significant risk factors is relatively uncommon and can pose diagnostic challenges. In this case report, we describe the case of a 26-year-old female with no pertinent past medical history who presented to ED with acute chest pain and was diagnosed with a subtotal occlusion of the mid obtuse marginal (OM) branch of the coronary artery requiring two drug eluting stents to be placed.
Looking at the Efficacy of SGLT2 Inhibitors in Heart Failure with Mildly Reduced and Preserved Ejection Fraction: A Systematic Review and Meta-Analysis
Authors: Menon Tushar
Published: June 2023

Due to the diverse etiologies and sub-phenotypes that characterize HFpEF (heart failure with preserved ejection fraction), it is challenging to treat all cases with a single medication [1,2]. As a result, patients with HFpEF and HFmrEF (Hear failure with mildly reduced ejection fraction defined as those with an EF of 40-49%) have few treatment alternatives. The current recommendations state that diuretics are suggested for HFpEF patients when needed to treat their symptoms [3,4]. The extensive range of pharmacotherapies that have been tried so far have not significantly improved the consequences for patients with HFmrEF or HFpEF. A crucial unmet need in the treatment of these individuals is the hunt for a pharmacotherapeutic drug that will reduce “hard endpoints,” such as mortality and serious cardiac events [5].

Authors: Paes Washington Elias
Published: June 2023

This article describes the phenomenon of creativity through an approach that focuses on linguistic aspects, beyond the narrative level of linguistic-literary description, based on the main theories of Linguistics. The concept of linguistic creativity, a phenomenon that only manifests itself in human language, is little explored and known in Languages and Literature, although it is extremely productive for writing practices, inside and outside the classroom. In the first part of the article, the concepts of writing, creative writing, creativity and linguistic creativity are discussed; in the second one, the relations between linguistic theories and creativity are discussed based on the concepts of phrase, paradigm, recursion, change, variation and grammaticalization; in the third part, we bring some points from the works of Guimarães Rosa. In the final considerations, we emphasize the expansion of the sense of “creativity”, in order to encompass all textual productions, as a means of making these productions more expressive. This work adopted a bibliographic review as a research methodology.

Disease is one of the main problems that have a major impact on aquaculture activities. Diseases in fish generally occur due to an imbalance of interactions between fish, pathogens, and the culture environment. Poor environmental quality can increase stress on fish and increase the pathogenicity of pathogens. In aquaculture activities, it is important to prevent disease in fish to avoid large economic losses. Based on the result of the initial survey, it was found that the problems faced by fish farmers in the Genteng area were the lack of knowledge in identifying the early syndrome of fish disease and the weakness in monitoring the quality of water for cultivation. This program aimed to provide the fish farmer with an introduction to disease kinds, training in environmental health management, and mentoring activities for aquaculture activities so that fish diseases can be prevented as early as possible. This programs were carried out on August 18, 2022, which was attended by 20 fish farmers in the Genteng area and continued with regular assistance for one month.

Published: June 2023

Cell culture using a 3D method provides Various cell culture strategies have been developed using synthetic or biological materials; most existing publications use many reagents. Bioscaffold from mouse embryonic fibroblast (MEF) enhances cell attachment, interaction, and production of growth factors. Since bioscaffolds could maintain and stimulate pluripotency of stem cells, we conducted this study to prove bioscaffold function. Bioscaffold was prepared from MEF cultured in  DMEM complete medium supplemented with dextran sulfate and L-ascorbic acid to increase extracellular matrix production. This medium acts as an embryo stem cell (ESC) culture medium. We used a Tali-cytometer to identify and quantify stem cells based on Sox2 and Oct4 proteins, markers of stemness. ESC culture using bioscaffold maintained the pluripotency of ESC as indicated by the presence of  Oct 4 and Sox2 as ESC markers compared to MEF culture. From this research, the bioscaffold from MEF can be developed as media for ESC to improve propagation. Furthermore, it is a model for tissue engineering and in vitro organ development.

Novel Strategy for the Demulsification of Peanut Oil Body by Caproic Acid
Authors: Gao Yuhang , Zheng Yanzhao , Yao Fei , Chen Fusheng
Published: June 2023

Aqueous enzymatic method is a green oil extraction technology with limited industrial application owing to the need for demulsification of the oil body intermediate product. Existing demulsification methods have problems including low demulsification rates and high costs, such that new methods are needed. Free fatty acids produced by lipid hydrolysis can affect the stability of peanut oil body (POB) at a certain concentration. After screening even-carbon fatty acids with carbon chain lengths below ten, caproic acid was selected for demulsification of POB using response surface methodology and a Box–Behnken design. Under the optimal conditions (caproic acid concentration, 0.22%; material-to-liquid ratio, 1:4.7 (w/v); time, 61 min; and temperature, 79 C), a demulsification rate of 97.87% was achieved. Caproic acid not only adjusted the reaction system pH to cause aggregation of the POB interfacial proteins, but also decreased the interfacial tension and viscoelasticity of the interfacial film with increasing caproic acid concentration to realize POB demulsification. Compared with pressed oil and soxhlet-extracted oil, the acid value and peroxide value of caproic acid demulsified oil were increased, while the unsaturated fatty acid content and oxidation induction time were decreased. However, the tocopherol and tocotrienol contents were higher than those of the soxhlet-extracted oil. This study provides a new method for the demulsification of POB.
How Czech Adolescents Perceive Their Physical Activity

Published: June 2023

Our study points out that there is a discrepancy between the self-perceived levels of own MVPA and VPA and the perceived descriptive norms of peers’ MVPA and VPA. Adolescents underestimate the prevalence of sufficient MVPA and VPA, and thus perceived descriptive norms in MVPA and VPA are worse than levels of own MVPA and VPA. These findings indicate room for targeted intervention based on the social norms based approaches to increase the physical activity of adolescents or at least strengthen their actual positive behaviour.
COVID-19 Disease and Menstrual-Related Disturbances: A Spanish Retrospective Observational Study in Formerly Menstruating Women

Published: June 2023

After three years of the onset of the pandemic, there is scarce evidence about how COVID-19 disease affect the female reproductive system, and consequently, the menstrual cycle. Since the common causes of secondary amenorrhea are considered as exclusion criteria in the studies about menstrual changes following SARS-CoV-2 infection, the prevalence of this event and the influencing factors in formerly menstruating women remains unknown. A retrospective observational cross-sectional study was conducted on Spanish adult women (N= 17,512), using an online survey; a subpopulation of SARS-CoV-2-infected-formerly menstruating women was included in the present analysis (n= 72). Collected data included general characteristics, medical history, and specific information about COVID-19 disease. 38.9% of the respondents experienced menstrual-related disturbances after suffering from the COVID-19 disease, unexpected vaginal bleeding being the most common (20.8%). Other alterations related with the length – “shorter” by 12.5% − and the flow − “heavier than usual” 30.3% − of the menstrual bleeding were reported. The binary logistic regression showed that being a perimenopausal woman (AOR 4.608, CI 95%, 1.018 – 20.856, p = 0.047) and having heavy menstrual bleeding (AOR 4.857, CI 95%, 1.239 – 19.031, p=0.023) are influential factors. This evidence could help health professionals to provide scientifically up-to-date information to their patients, empowering them to actively manage their reproductive health, especially in those societies where menstrual health is still a taboo.
Deep Learning-Based Human Chromosome Classification: Data Augmentation and Ensemble
Authors: D'Angelo Mattia , Nanni Loris
Published: June 2023

Object classification is a crucial task in deep learning, which involves the identification and categorization of objects in images or videos. Although humans can easily recognize common objects, such as cars, animals, or plants, performing this task on a large scale can be time-consuming and error-prone. Therefore, automating this process using neural networks can save time and effort while achieving higher accuracy.

Our study focuses on the classification step of human chromosome karyotyping, an important medical procedure that helps diagnose genetic disorders. Traditionally, this task is performed manually by expert cytologists, which is a time-consuming process that requires specialized medical skills. Therefore, automating it through deep learning can be immensely useful.

To accomplish this, we implemented and adapted existing preprocessing and data augmentation techniques to prepare the chromosome images for classification. We used ResNet-50 convolutional neural networks and an ensemble approach to classify the chromosomes, obtaining state-of-the-art performance in the tested dataset.

Published: June 2023

Drowsiness detection is an important task in road safety and other areas that require sustained attention. In this article, an approach to detect drowsiness in drivers is presented, focusing on the eye region, since eye fatigue is one of the first symptoms of drowsiness. The method used for the extraction of the eye region is Mediapipe, chosen for its high accuracy and robustness. Three neural networks were analyzed based on: InceptionV3, VGG16 and ResNet50V2 that implement deep learning. The database used is NITYMED, which contains videos of drivers with different levels of drowsiness. The three networks were evaluated in terms of accuracy, precision and recall in detecting drowsiness in the eye region. The results of the study show that all three convolutional neural networks have high accuracy in detecting drowsiness in the eye region. In particular, the Resnet50V2 network achieved the highest accuracy, with a rate of 99.71% on average. For better visualization of the data, the Grad-CAM technique is used, with which we get a better understanding of the performance of the algorithms in the classification process.
The Impact of CC16 on Pulmonary Epithelial-Driven Host Responses during Mycoplasma pneumoniae Infection

Published: June 2023

CC16 plays many protective roles within the lung; however, the complete biological functions, es-pecially regarding the pulmonary epithelium during infection, remain undefined. We have previ-ously shown that CC16 deficient (CC16-/-) mouse tracheal epithelial cells (MTECs) have enhanced Mp burden, compared to CC16 sufficient (WT) MTECs; therefore, in this study, we wanted to fur-ther define how the pulmonary epithelium responds to infection in the context of CC16 deficiency. Using mass spectrometry and quantitative proteomics to analyze proteins secreted apically from MTECs grown at an air-liquid interface, we investigated the protective effects that CC16 elicits within the pulmonary epithelium during Mycoplasma pneumoniae (Mp) infection. When chal-lenged with Mp, WT MTECs have an overall reduction in apical protein secretion, whereas CC16-/- MTECs have increased apical protein secretion compared to their unchallenged controls. Fol-lowing Gene Ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) assessment, many of the proteins upregulated from CC16-/- MTECS (unchallenged and during Mp infection) were related to airway remodeling, which were not observed by WT MTECs. These findings sug-gest that CC16 is instrumental in providing protection within the pulmonary epithelium during respiratory infection with Mp, the major causative agent of community-acquired pneumoniae.
The Potential of Replacing Concrete with Sand and Recycled Polycarbonate Composites: Compressive Strength Testing
Authors: Woods Morgan C. , Kulkarni Apoorv , Pearce And Joshua M.
Published: June 2023

Concrete contributes 8% of all global carbon emissions making the need to find substitute critical for environmental sustainability. Research has indicated the potential for recycled plastics to be used as concrete substitutes. This study extends existing research by investigating the use of polycarbonate (PC) in plastic sand bricks as a mechanical equivalent to concrete. PC has high compressive strength, durability, impact strength, thermal resistivity, clarity, fatigue resistance, and UV resistance. This work provides a method and mold to produce a matrix of sand-plastic sample compositions with dimensions adhering to ASTM D695 standard for compressive properties of rigid-plastic. Compositions of 0% (control), 20%, 30%, 40%, and 50% sand by weight were tested. Samples were tested for compressive strength until yield and stress-strain behaviors plotted. The results for 100% PC demonstrated an average and maximum compressive strength of 71 MPa and 72 MPa, respectively. The 50% PC and 50% sand composition yielded an average and maximum compressive strength of 71 MPa and 73 MPa respectively with an increase in compressive stiffness, and transition to shear failure resembling cement. With a composite density of 1.86 g/cm3 against concrete’s average 2.4 g/cm3, and a compressive strength exceeding commercial concrete demands of 23.3 MPa to 30.2 MPa, this lightweight alternative meets the strength demands of concrete, reduces the need for new construction materials, and provides an additional recycling opportunity for nonbiodegradable waste plastic.
Investigating the Potential Adoption of Product-Service Systems in the Luggage Industry To Promote Sustainability
Authors: Wilson Donald , Iacovidou Eleni
Published: June 2023

The travel-goods industry is an essential part of the larger travel and tourism sector, but it creates significant environmental impacts due to resource and energy consumption. This study investigates the feasibility and sustainability potential of servitisation concepts within the travel-goods industry, and the Product-Service System (PSS) models, in particular, to identify steps towards a more sus-tainable travel industry in the future. It explores the sustainability-related drivers within the luggage industry and identifies barriers to the adoption of servitisation models, and opportunities for value creation for both consumers and commercial organisations. Business models are mapped into a ty-pology to highlight different pathways to PSS adoption, underpinned with empirical data collected via a consumer sentiment survey and semi-structured interviews with industry experts. Even though the analysis revealed shifting consumer attitudes towards servitisation concepts within the travel-goods market, with a significant level of interest emerging for specific PSS models, at present, the widespread adoption of PSS is hindered. This is due to the fragmented nature of global supply chains and entrenched ownership values. Addressing supply chain issues regarding end-of-life systems to sustainably manage products beyond functional obsolescence is critical. In parallel, product-oriented PSS models are more likely to increase, driven by a burgeoning resale market and supported by digi-tal technologies, which in turn can lead to greater prospects for use-oriented PSS adoption and even-tually, reduced environmental impacts.

Published: June 2023

In August 2022, in the Moscow region, Russia, on a backyard farm, the mortality was observed at chickens and all 45 birds of this farm died or were slaughtered after onset of symptoms within a few days. Paramyxovirus was isolated from diseased birds. Based on the nucleotide sequences of the F and NP gene fragments, the belonging of virus to subgenotype VII.1 AAvV-1 class II was established. The cleavage site of the F gene 109SGGRRQKRFIG119 and T in 546 and 555 position of NP gene, were typical for the velogenic type. The genetically closest NDV isolates were found in Iran. The mean time of death of 10-day-old chicken embryos upon infection with the minimal infectious dose was 52 hours, which is typical for the velogenic pathotype. The virus caused 100% death of six-week-old chickens during oral infection, as well as 100% mortality of all contact chickens, including those located in remote cages, which proves the ability of virus to spread not only by fecal-oral but also by aerosol route. That demonstrates a high level of pathogenicity and contagiousness of the isolated strain for chicken. However, the mice intranasally infected with high doses of the virus had not die.

Published: June 2023

Lithium-ion batteries serve as the primary sources of power for electric vehicles (EVs) and hybrid electric vehicles (HEVs). For vehicle applications, battery management systems (BMSs) are nec-essary to protect lithium-ion batteries from overheating and to ensure optimum vehicle perfor-mance. Our approach to developing a BMS was based on recent advances in the application of phase field models for lithium-ion batteries. In particular, our reduced-order model (ROM) uti-lized a dataset generated from the COMSOL® Multiphysics simulation of the Cahn–Hilliard equation for a single particle of a lithium iron phosphate (LiFePO4) cathode: an example of using a reduced-order model (ROM) based on a single-particle model (SPM). The main innovation of our ROM is that the SPM is fully coupled to a heat transfer model at the battery cell level. We utilized principal component analysis to identify a lower-order model that could reproduce the battery’s voltage and temperature response for ambient temperatures ranging from 253 to 298 K and for discharge rates ranging from 1 C to 20.5 C. The reduced-order dataset was then fitted to the ex-perimental data for an A123 Systems 26650 2.3 Ah cylindrical battery using deep neural network (DNN) regression.

It introduces further advances with respect to the original proposal by Nardini and Brierley. And it explores explicitly the ability of the algorithm and associated tools to work properly on significantly different rivers while adopting a given same parametrization. This was indeed an envisaged ability speculated as a challenging conclusion of the previous work. The Duqueco, Laja and Biobío rivers (Chile) are analyzed for this purpose. The conclusion is definitely positive, what opens future promising application horizons.

In recent years, intelligent identification and prediction of ore deposits based on deep learning algorithm and image processing technology has gradually become one of the research frontiers in the field of geological and metallogenic prediction. However, this method also has many problems that need to be solved. For example, (1) very few trainable image samples containing mineral point labels; (2) The geological image features are small and irregular, and the image similarity is high; (3) It is difficult to calculate the influence of different geological prospecting factors on ore mineralization. Based on this, this paper constructs a deep learning network model Multiscale Feature Attention Framework (MFAF) based on geo-image data. The results show that MFCA-Net module in MFAF model can solve the problem of scarce mine label images to a certain extent. In addition, the channel attention mechanism SE-Net module can quantify the difference of influence of different source factors on mineralization. The prediction map is obtained by applying the MFAF model in the study of deposit identification and prediction in the research area of the southern section of Qin-hang metallogenic Belt. In the forecast map, many regions have high metallogenic potential. Through observation, it is found that the above predicted area covers 100% of the known ore deposits at present, which has a good prediction effect. Later, we can find out the specific reasons through field verification. The multi-scale feature fusion and attention mechanism MFA Framework in this paper can provide a new way of thinking for geologists in mineral exploration. The research of this paper also provides resource guarantee and technical support for the sustainable exploitation of mineral resources and the sustainable growth of society and economy.

Anaerobic digestion has emerged as an increasingly popular method for the effective management of organic waste and wastewater with the potential to generate renewable energy. However, efficient digestion depends heavily on the complex and diverse microbial communities mediating this process. This review paper delves into the complex microbiome that exists within anaerobic digestion digesters, playing a critical role in the efficient and sustainable conversion of organic waste into biogas. Its primary focus falls within the scope of how various operational and environmental factors, including temperature, pH, hydraulic retention time, substrate loading rates, and the presence of inhibitory compounds, can substantially impact the microbiome of these systems. Through an extensive analysis of the existing literature, the microbial ecology of anaerobic digestion, including the composition and function of the microbial community, their interactions, and responses to different stressors, are evaluated. By offering critical insights into the distribution patterns of active microbial populations upon alterations in various process parameters, a better understanding of the microbial dynamics within these systems is provided, enhancing their efficiency. Overall, this paper emphasizes the importance of unraveling the microbial evolution within AD reactors to optimize biogas production and sustainable waste management and proposes future perspectives in this direction.

Applying of blood biopolymers to regulate the phase composition is promising in designing the hydroxyapatite-based hybrid biomaterials with controllable resorbability. Hybrid materials based on hydroxyapatite and platelet-poor plasma (PPP) were formed in conditions of chemical precipi-tation at pH 11, [Ca2+] / [PO43–] ratio 1.67, PPP volume fraction of 6–24%, maturing time of 4–9 days. Mineral component of the materials was represented as 53% hydroxyapatite / 47% amor-phous calcium phosphate after 4 days of maturation, and 100% hydroxyapatite after 9 days of maturation. Varying PPP content from 6% to 24% provided forming of materials with rather de-fined content of amorphous calcium phosphate and biopolymer component, having desired mor-phology ranging from typical apatitic conglomerates to hybrid apatite-biopolymer fibers. Co-precipitated hybrid materials based on hydroxyapatite and PPP are promising for bone regen-eration in osteoplastic and maxillofacial applications.

This manuscript presents a system that can generate a 2D grid map and a 3D voxel model of an environment by fusing multiple sensors integrated into a robot. The fusion of these sensors is done by utilizing Robot Operating System (ROS) and some of its libraries. The sensors that are fused in the robot are a Light Detection and Ranging (LIDAR), Inertial Measurement Units (IMU), wheel encoders, and a Time-of-Flight camera. With the fusion of the point cloud data information obtained with the Time-of-Flight camera, the laser information of the LIDAR sensor, in addition to the odometry generated with the other sensors, a 2D grid map and a 3D model of two different environments were created, thus testing the performance of the system.

Published: June 2023

In this paper, we propose a methodology for analyzing the near-field coupling between two surface mount device (SMD) inductors using a 3-dimensional electromagnetic (3D-EM) model. To develop the 3D-EM model, we first extract the effective permeability of core magnetic material in the SMD using the loss tangent in the equivalent circuit model. Then the effective permeability is used in the magnetic material for the 3D-EM modeling of SMD inductor. The validity of the proposed 3D-EM model is confirmed by comparing the impedance and S-parameters obtained from both measured and EM-simulated values for the two near-field coupled SMDs. Finally, the near-field coupling effects between the two adjacent SMD inductors are visualized in terms of magnetic coupling path visualization (CPV) using the proposed 3D-EM model, which demonstrates its usefulness for near-field coupling analysis.

Purpose: This study aims to provide a foundational understanding of patient-centric perceptions of telemedicine implementation in rural Minnesota. Methods: This retrospective cohort study utilized a mail questionnaire to assess patient attitudes and behaviors regarding telemedicine during the emergency response to COVID-19. The target population was patients of a Primary Care clinic in eastern Minnesota. Descriptive statistics were used to assess respondents’ level of agreement with survey items scored on a 0-10 scale. Results: A majority of the respondents indicated that they were satisfied with using telemedicine (73.96%); that they gained an additional sense of control over their health condition due to the availability of telemedicine (52.08%); that they would support the use of telemedicine in the future (61.05%); that telemedicine increased access to care (65.63%); telemedicine was preferred over the clinic (61.46%), and that they would purchase new equipment to increase the utility of telemedicine services (54.17%). 51.04% of the respondents indicated a 10/10 level of satisfaction with telemedicine services. 48.96% indicated the strongest level of disagreement related to difficulty using telemedicine or a preference for in-person clinical appointments. Conclusions: Patients were found to have favorable perceptions of telemedicine overall. Though providers continue to recognize the benefit of face-to-face visits, their patients show an increased predilection for virtual care and telemedicine will likely remain an essential tool for providers to reach patients who would otherwise choose not to seek care.
