Authors: Chomkitichai Weerasak , Ubolsook Putthadee , Jansanthea Pongthep 
Published: November 2024

Abstract

This study explores the synthesis, characterization, and photocatalytic efficiency of Fe₂O₃/BiVO₄ nanocomposites for sustainable environmental remediation. Fe₂O₃ and BiVO₄, both semiconductor materials, exhibit complementary properties, making them promising candidates for synergistic photocatalysis. The nanocomposites were synthesized by varying the Fe ratio using a hydrothermal method followed by calcination. Several techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDS), Brunauer-Emmett-Teller (BET) surface area analysis, UV-visible diffuse reflectance spectroscopy (UV-DRS), and photoluminescence (PL) analysis, were employed for characterization. XRD confirmed the rhombohedral structure of Fe₂O₃ and the monoclinic structure of BiVO₄. SEM and TEM images revealed uniform particle dispersion, with ~ 500 nm BiVO₄ particles surrounded by ~ 50 nm Fe₂O₃ aggregates. BET analysis showed that the surface area increased with Fe content. UV-DRS demonstrated visible light absorption with bandgap energies from 2.27 to 2.47 eV, suitable for photocatalytic applications. PL analysis indicated efficient charge separation due to reduced photoluminescence. Photocatalytic degradation of methylene blue (MB) revealed that the 2Fe/8Bi nanocomposite achieved the highest degradation efficiency (98.74%) with a rate constant of 0.0270 min⁻¹, outperforming individual Fe₂O₃ and BiVO₄. These results demonstrate the potential of Fe₂O₃/BiVO₄ nanocomposites as sustainable photocatalysts for environmental remediation, with promising prospects for addressing environmental challenges.

Published: November 2024

Abstract

Coronary artery disease (CAD) is a prevalent condition among chest pain patients, and accurate prediction of the disease is crucial to ensure timely interventions and improve patient outcomes. We aim to elaborate a prediction model for CAD in chest pain patients using machine learning approaches. A retrospective analysis was performed using electronic health records of patients who presented with chest pain at seven hospitals. A total of 8474 patients were included in the study, where 63.25% were diagnosed with CAD. The data included demographic information, medical history, and laboratory results. Machine learning algorithms, including Random Forest, CatBoost, XGBoosting, Gradient Boosting, Light Gradient, AdaBoost, Ridge Classifier, Linear Discriminant, Logistic Regression, Decision Tree, SVM, Quadratic Discriminant, K Neighbors, Naive Bayes, and Dummy Classifier were trained and evaluated to predict the presence of CAD.The prediction model achieved an overall accuracy of 0.766 in identifying CAD in chest pain patients. The sensitivity and precision were 0.938 and 0.746, respectively. Important predictors for CAD included age, pulse rate, monocyte, and red cell distribution width SD. The eXtreme Gradient Boosting showed the best performance (area under the receiver operating characteristics, AUROC, 0.820, and 95% CI, 0.801–0.839) Additionally, the model demonstrated robust performance in the validation group. This study successfully developed and validated a prediction model for CAD in chest pain patients using machine learning techniques. The model exhibited good predictive ability and could aid in the early identification of CAD in clinical practice, potentially leading to appropriate interventions and improved patient outcomes.

Published: November 2024

Abstract

Tribolium castaneum (Herbst), which resides in shaded areas avoiding daylight, has developed various adaptation strategies to cope with ultraviolet (UV) stress. In this study, we utilized 16S rRNA amplicon sequencing to assess the diversity of the bacterial communities within T. castaneum following exposure to ultraviolet-A and ultraviolet-B for different durations, and to elucidate the role of microbiome in host response to UV stress. This study revealed that UV irradiation affected the relative abundance of bacterial community within T. castaneum, rather than its species richness. The significant differences were observed in the relative abundance of Proteobacteria and Cyanobacteria, among the comparison of UV irradiation groups at phylum level. Most genes coded by bacteria were annotated on membrane transport, replication and repair, amino acid metabolism, energy metabolism and carbohydrate metabolism with reference to Kyoto Encyclopedia of Genes and Genomes database. However, the significant differences identified in this study were limited, making it challenging to establish a clear relationship between UV irradiation and the bacteria within T. castaneum larvae. Consequently, we propose the viewpoint that the role of bacteria in contributing T. castaneum against UV stress may have been diminished during their development due to the low-UV rearing conditions.

Published: November 2024

Abstract

Background
This retrospective study aimed to summarize the application of 3-dimensional(3D) reconstruction via modified pulmonary artery computed tomography angiography(CTA), as well as to compare the surgical outcomes of 3D versus high resolution CT(HRCT) in anatomic pulmonary segmentectomy(APS).
Methods
A total of 93 patients who underwent thoracoscopic APS were enrolled in the study. They were divided into 3D group (n = 30) and HRCT group (n = 63), and than matched at 1:1 ratio using the propensity score matching (PSM) method. Clinical characteristics, surgical status, and postoperative recovery were compared between two groups, additionally, variations of segmental structures were summarized.
Results
60 cases were matched by PSM with 30 cases in each group. There were no significant differences between two groups in clinical characteristics, intraoperative blood loss and postoperative recovery (including total chest drainage, length of postoperative hospital stay)(P > 0.05 for all). 8(26.7%) patients in 3D group manifesting unique variations of segmental structures underwent anatomical segmentectomy accurately. Despite the 3D group exhibited higher anatomic variations compared to the HRCT group, it demonstrated shorter operation times and lower incidence of pulmonary infection. (P < 0.05 for all).
Conclusion
Preoperative 3D reconstruction has advantages in APS, particularly for patients with complex anatomic variations. Reconstruction via modified pulmonary artery CTA is also feasible for preoperative planning and intraoperative navigation in thoracoscopic APS.

Abstract

Background
Cardiovascular (CV) disease is the leading cause of death among U.S. women, yet women have a limited understanding of their CV-related morbidity and mortality risks. Provider-, system-, and patient-level barriers point to a need for multi-level evidence-based strategies to facilitate CV risk reduction. Guided by the Replicating Effective Programs framework and complexity theory, we implemented a CV Toolkit in primary care clinics for women Veterans. The objective was to evaluate the effect of implementation of CV toolkit on participation in behavior change programs that target CV risk reduction.
Methods
In partnership with the Veterans Health Administration (VA) Office of Women’s Health and National Center for Health Promotion and Disease Prevention, we developed and implemented a CV Toolkit at five geographically diverse VA sites between March 2017-March 2020. Using a non-randomized stepped wedge design, we evaluated the effect of the implementation of toolkit on participation in the VA MOVE! weight management program, and on participation in health promotion and disease prevention (HPDP) programs (coaching, facilitated groups, etc.) and/or complementary integrative health (CIH) programs (yoga, meditation, etc.). We utilized a three-level (patient, site, time) non-linear fixed effect model with stratification by age (65 and older versus younger). Patient participation, utilization, and demographics were extracted from VA administrative data for all women with at least one primary care visit at a participating site from December 2016-March 2020 (n = 6009).
Results
Women were on average 45 years old; 38% were white, 31% Black, 17% Hispanic; and over a third had CV risk factors and/or mental health diagnoses. For women 65 years and older (n = 540), active toolkit implementation resulted in increased odds of MOVE! participation (OR = 1.09; 95% CI:1.030–1.152) compared to when the toolkit was not active either within or between sites. Women younger than 65 (n = 5469) had increased odds of using HPDP/CIH programs during active toolkit implementation (OR = 1.01; 95% CI:1.002–1.022).
Conclusions
Active implementation of the CV Toolkit intervention was significantly associated with increasing participation in behavior change programs. Variation in program participation by age suggests that the diversity of behavior change programs available to women Veterans may facilitate participation across the lifespan.

The effect of a price reduction intervention on healthier menu items in the out-of-home food sector on energy purchased and consumed: a restaurant-based pilot experiment
Authors: Witkam Rozemarijn , Brealey Jane , Latham Rebecca , Jones Andrew , Robinson Eric 
Published: November 2024

Abstract

Background
Frequent out-of-home food sector (OOHFS) use is associated with poor dietary intake and obesity. There are limited real-world studies on pricing interventions to encourage healthy eating in the OOHFS. We performed a pilot study to collect preliminary trial data on the potential impact of a price reduction intervention on healthier menu items on purchasing and consumption of kilocalories (kcal) in a full-serviced restaurant among people from both lower and higher socioeconomic position (SEP).
Methods
The main trial design was a pre vs. post price reduction comparison (within-subjects), where participants (adults aged ≥ 18 years) received a control menu with standard pricing at visit 1 and a menu with price manipulations (30% reduction for healthy items) at visit 2. A sub-study was conducted with a comparison sample to estimate potential pre-post changes to outcome variables in the absence of a pricing intervention. Linear mixed models assessed pre-post changes in kcal purchased and kcal consumed.
Results
In total, 114 participants were recruited; 92 were randomised to the main study and 22 to the comparison sub-study. Of those participating in the main study, 78 completed and 14 were lost to follow-up. There were no participants lost to follow-up in the comparison study. Of the completers, 46 participants were considered higher SEP (i.e. bachelor’s degree or higher) and 32 participants were lower SEP (i.e. some college or associate degree or lower). Kcal purchased and consumed decreased from visit 1 to visit 2; however, this reduction was only statistically significant for total kcal consumed (regression coefficient: -98.0 (95% CI -181.9, -14.2), p = 0.02). There were no notable intervention effect differences between higher and lower SEP participants. In the comparison study, kcal purchased and consumed was also lower at visit 2 compared to visit 1, although this should be interpreted with caution due to the small sample size.
Conclusion
A price reduction intervention on lower energy menu items is potentially effective in encouraging healthier eating in a restaurant setting. Larger studies with inclusion of a control group (e.g., randomised controlled trials) are now needed to confirm intervention effects and whether they are equitable across different socioeconomic groups.

Published: November 2024

Abstract

Given the significance of dynamic taste perception, this study focused on sucrose and citric acid as research subjects to investigate quantitative principles governing the dynamic interactive responses between sweet and sour taste perception. Time-intensity experiments revealed a logarithmic correlation between Imax, AUC and concentration, indicating that the sweetness of 2–10% sucrose and sourness of 0.006–0.024% citric acid exhibited mutual inhibition. Temporal dominance of sensations study revealed that during the initial stage, the predominant attributes were sweetness and sourness, while in the later stage, salivation emerged as the dominant attribute across varying ratios of sweet-dominant, sour-dominant, and balanced sweet-sour sensations. At various sweet-to-sour ratios, dynamic liking evaluation determined the optimal acceptance ratio of sweet-to-sour and elucidated the influential attributes of perceived preference along with their operational principles. The aforementioned research findings on the dynamic sweet-sour taste interaction patterns hold substantial implications for informing practical applications in the food industry.

Adaptive Detection Strategies for Enhanced BER Performance in MIMO Visible Light Communication Systems
Authors: Kumar Ajit 
Published: November 2024

Abstract

This study investigates the Bit Error Rate (BER) performance of a 4×4 MIMO visible light communication (VLC) system using several detection techniques, including Minimum Mean Square Error (MMSE), Maximum Likelihood Detection (MLD), Adaptive Zero-Forcing (ZF), and Beamforming. The evaluation is conducted across multiple scenarios involving variations in transmitter separation (dtr), receiver separation (drx), field-of-view (FOV), and half-power semi-angle (HPSA). Results reveal that beamforming consistently outperforms other detection methods at higher SNR levels, while at lower SNR levels, MLD yields the lowest BER, followed by Adaptive ZF and MMSE. Optimal BER performance occurs with a receiver separation of 40 cm when LED separation is fixed at 2.5 m. With fixed PD separation, the BER is minimized at a 2 m separation between LEDs. For different FOV settings, each detection method achieves optimal BER at specific FOV angles: pseudo-inverse, MMSE, and Adaptive ZF perform best at 60 degrees, while MLD and beamforming show improved BER at 50 degrees. Additionally, varying the HPSA shows that all detection methods perform best at an HPSA of 40 degrees.

Abstract

Optically pure non-natural β-amino acids are noteworthy molecular motifs of numerous pharmaceutically important molecules. Skeletal editing of abundant α-amino acid scaffolds via tandem radical 1,2-N-shift/cross-coupling represents an attractive and powerful tool to straightforward assemble new β-amino acid molecules; however, this strategy presents substantial challenges owing to difficulties in reactivity and regio-/enantiocontrol. Herein, we report an unprecedented remote cross-electrophile C(sp2)-C(sp3) coupling of β-bromo α-amino acid esters with aryl bromides via a π-system-independent 1,2-N-shift, which allows access to α-arylated β-amino acid motifs with high efficiency and regioselectivity. Furthermore, upon the novel cooperative catalysis of the Ni(II)/new-style Box complex and chiral phosphoric acid (CPA), this migratory coupling further achieves high enantioselectivity control in C(sp3)–C(sp2) bond construction. In addition, detailed experimental studies and DFT calculations were conducted to gain insight into the mechanism and origin of the enantioselectivity, which was further evidenced by the two-step synthesis of a pan-Akt inhibitor molecule. Overall, this novel synergistic strategy expands these methods to the challenging enantioselective remote C(sp2)–C(sp3) cross-electrophile coupling via π-system-independent radical 1,2-amino migration.

Case Report of Asymptomatic Kikuchi-Fujimoto Disease
Authors: Alija Onita , Chitanvis Maneesha , Mema Eralda 
Published: November 2024

Background:
Kikuchi-Fujimoto Disease (KFD) is a rare condition, distinguished by its hallmark presentation of regional lymphadenopathy in young adult
females. While initially observed to exclusively affect cervical lymph nodes in females under 40 years old, KFD is now known to impact
individuals of any age or gender and manifest with adenopathy in various anatomical sites. Nonspecific imaging findings for KFD include enlarged
lymph nodes, often exhibiting abnormal morphology

Case Presentation:
In this study, we present the case of a 49 year old asymptomatic woman, in whom several enlarged left axillary lymph nodes were incidentally
noted during routine mammography. The diagnosis of KFD was determined via ultrasound-guided core needle biopsy. Histological examination of
the biopsied lymph node revealed necrotizing lymphadenitis, consistent with KFD.

Conclusion:
The uncommon and broad presentation of KFD highlights the significance of acquiring tissue samples to distinguish this condition from
resembling malignancies or autoimmune disorders.
