Hair follicles (HF) are important anatomical structures that are responsible for maintenance of the hair cycle. However, hair disease can affect the hair follicle directly with the modern treatment still riddled with side effects due to lack of full understanding of hair nature. The study aimed to investigate the effect of alginate hydrogel with extracellular matrix (ECM) protein encapsulation on activity of dermal papilla (DP) spheroids. The DP cells were aggregated to mimic its native spherical structure and introduced into alginate solution mixed with ECM. The mixture was then crosslinked with calcium chloride to form hydrogel. The encapsulation elevated alkaline phosphatase (ALP) activity, which is a DP molecular marker. This work demonstrates that DP encapsulation in alginate with ECM can manipulate DP spheroid activity. © 2024 IEEE.

Efficient data collection in wireless sensor networks (WSNs) is crucial. While traditional approaches rely on stationary data sinks, the use of mobile sinks, like unmanned aerial vehicles (UAVs), has shown promise in enhancing data-gathering capabilities. However, existing methods often overlook the importance of trust, leaving the network susceptible to malicious or faulty nodes. To address this issue, we propose a novel trust-aware data-gathering algorithm, Variable Length Multi-Objective Whale Optimization Data Gathering (VLMOWO-DG). Our algorithm simultaneously optimizes energy consumption, delay, and trust while employing mobile sinks to collect data from sensor nodes. By considering trust as a key performance metric, we improve data reliability and security. The VLMOWO-DG algorithm introduces flexibility through variable-length solution representation and application-oriented operators, allowing for efficient exploration of the solution space. Simulation results demonstrate that our proposed algorithm significantly outperforms established benchmarks, NSGA-II and NSGA-III, in terms of domination and hypervolume. This leads to a remarkable improvement of 200% in data gathering performance. © 2015 The Authors.

Osteoporosis is a common disease characterized by low bone density and structural deterioration of bone tissue. For a successful course of treatment and fracture avoidance, early diagnosis of this disease is essential. The aim was to provide a novel method for osteoporosis prediction using Artificial Intelligence (AI)-based framework. The purpose was to predict the likelihood of osteoporosis based on the Bone Mineral Density (BMD), along with other characteristics such as age, weight, height, gender, and Body Mass Index (BMI) extracted from medical reports and images collected from a comprehensive medical center in Lebanon. Three machine-learning algorithms were implemented and tested, Logistic Regression (LR), Support Vector Machines (SVM), and Decision Trees (DT). Variety of quantitative statistical metrics were used to evaluate the performance of our framework, upon training and testing our algorithms. The metrics that were employed to evaluate our results included accuracy, precision, sensitivity, and F-score, in addition to the Receiver Operating Characteristic (ROC) Curve and the Area Under the Curve (AUC). Experimental Results demonstrated that both the SVM and LR algorithms achieved the highest accuracy of detection of osteoporosis as compared to existing algorithms applied in this field, with an accuracy of 89%. The sensitivity of diagnosis obtained was 98% by LR and 97% by SVM and surpassed the sensitivity obtained by DT. As such LR showed the best performance. The output of the algorithms could help medical doctors assess patients automatically. These findings demonstrated the potential of AI in osteoporosis prediction and thus prevention, highlighting the significance of early diagnosis. Thereby as a future prospect, choosing carefully the framework is crucial and additional algorithms have to be considered and tested. © 2023 IEEE.

Corrosion is a detrimental persistent industrial conundrum that can cause the failure of operating equipment and weakening of construction assemblies, thus threatening the lives of humans, and accelerating the consumption of the natural metals reservoirs. In this study, we deployed green silver nanoparticles (AgNPs) as corrosion inhibitors for mild steel. Citrus aurantium peels aqueous extract (CAPE) mediated the bio-reduction of silver ions (Ag+) into silver nanoparticles (AgNPs) under optimized experimental conditions. The prepared nanoparticles were comprehensively characterized by various techniques for size, morphology, optical properties, crystallinity, and elemental composition. Phytochemical analysis showed that the plant extract is rich in phenolic compounds that facilitated the formation of metallic silver from Ag+ ions. The anticorrosion properties of CAPE and CAPE-AgNPs for mild steel in 0.5 M HCl were investigated by potentiodynamic polarization and electrochemical impedance spectroscopy techniques. The biosynthesized CAPE-AgNPs were more efficient than CAPE in slowing down corrosion with inhibition efficiency of 70% attained at 1000 ppm of the inhibitor. CAPE and CAPE-AgNPs acted as mixed-type corrosion inhibitors with dominance over the cathodic reaction. Fitting the experimental data into different isotherms demonstrated that the corrosion inhibition was an endothermic process that took place through physical adsorption. CAPE-AgNPs significantly reduced pitting and localized damage on the metal surface. These findings highlighted the utility of CAPE-AgNPs as efficient corrosion inhibitors in different industrial settings. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.

This study reports the fabrication and characterization of schizophyllan (SPG) - gelatin hydrogel scaffolds for biomedical applications. SPG, a β-glucan polysaccharide, was selected for its unique biological activities, while gelatin provided cell-binding motifs to enhance cellular interactions. The gelation time of the hydrogels were evaluated using the tube inversion method, revealing the rapid formation of a stable network structure. Scanning electron microscopy (SEM) analysis demonstrated the highly porous and interconnected microstructure of the hydrogel scaffolds, which is crucial for facilitating cell infiltration and nutrient transport which indicated average pore size of approximately 6550.619 ± 4931.847 μ ~m. Fourier-transform infrared (FTIR) spectroscopy confirmed the formation of aldehyde groups at 2905 ~ cm-1 in oxidized SPG, forming Schiff base linkages between the oxidized schizophyllan and gelatin was observed at 1572 ~ cm-1 within the hydrogel network with suitable swelling behavior of 1 5 to 2 0 fold. Additionally the gelation time was estimated about 3 to 5 minutes. The combination of SPG, gelatin, and borax resulted in the fabrication of a biocompatible hydrogel scaffolds with appropriate properties for tissue engineering applications. © 2024 IEEE.

Research on biomedical engineering 2024年第3-4期40卷 835-849页

作者： de Souza, Daniel Baldoino Barreto, Cassiana Gabriela Lima Milagre, Selma Terezinha Pereira, Adriano Alves University Hospital of the Federal University of Santa Catarina Florianópolis Brazil Centre for Innovation and Technology Assessment in Health Faculty of Electrical Engineering Postgraduate Program in Electrical and Biomedical Engineering Federal University of Uberlândia Uberlândia Brazil

Background: Acute respiratory distress syndrome (ARDS) is a severe condition where lung alveoli fill with fluid, depriving organs of oxygen and risking death. Mechanical ventilation is conventional for oxygen therapy, but extracorporeal membrane oxygenation (ECMO) may be needed for refractory ARDS cases. This study aims to compare ECMO's impact on mortality and hospital stay versus conventional treatment for patients aged 12 or older with moderate or severe ARDS in intensive care units (ICUs). Methodology: Four independent reviewers followed the PRISMA-P method for the review. The key question used the PICOS tool. Databases searched included Cochrane Library, Bireme, MEDLINE, EMBASE, Web of Science, Scielo, LILACS, and grey literature to minimize publication bias. Selected papers were randomized controlled trials (RCTs) without language restrictions, meeting predefined inclusion and exclusion criteria. RoB-2 assessed bias risk, and GRADE evaluated evidence quality. Mortality was analyzed using a fixed-effect PETO method (odds ratio), and hospital stay was treated as a continuous variable using inverse variance and standardized mean difference (SMD). Results: We found 3,774 articles and selected 6 studies with 1,050 participants. Of these, 519 were allocated to the intervention group (ECMO) and 531 to the conventional treatment group (MV). The risk of bias for 3 studies was "some concerns," and 3 were "high risk of bias," mainly due to "deviations from intended/planned interventions" and "selection of reported outcomes." The primary outcomes for 30-day, 60-day, 90-day, and 180-day mortality showed odds ratios of 0.90 (95% CI: 0.66–1.21), 0.78 (95% CI: 0.50–1.21), 0.90 (95% CI: 0.66–1.21), and 0.62 (95% CI: 0.36–1.06) respectively, with low heterogeneity (I2 0.10). The secondary outcomes for a total length of stay and ICU stay showed standardized mean differences of 0.39 (95% CI: 0.13–0.65) and 0.33 (95% CI: 0.05–0.60) respectively, with substantial heterogeneity (I2
