A 3-Amino-Propyl Trimethoxy Silane (APTS) functionalized silica was prepared and investigated. The functionalized silica showed a powerful removal behavior towards Chromium (III) [Cr (III)] and Cadmium (II) [Cd (II)] ions in aqueous solution. The different factors affecting the heavy metal ions adsorption on these substrates such as pH, initial concentration, contact time, and temperature were investigated. FT-IR analyses were carried out to characterize the functionalization of salicylaldehyde unto 3-aminopropyl silica. Results showed that optimum adsorption of the metal ions occurred at a pH of 7 and 6 by the pure silica and functionalized silica respectively. Removal efficiencies of the adsorbents showed the trend: Salicylaldehyde-APTS modified > pure silica. The adsorption was described by the Langmuir adsorption isotherm. The kinetic results showed that the adsorption described well with pseudo-second order kinetic model. The study reveals that both pure silica and functionalized silica can be used as good adsorbents for the removal of the heavy metal pollutants from aqueous solutions and may be applied in the treatment of industrial waste waters and may be useful in detoxifying our already polluted environments.

Authors: Kurt Cemal
Published: January 2025

This study aimed to evaluate the diversity in fatty acid, lignan and tocol composition among different sesame accessions from 13 other countries. Fifty sesame genotypes were investigated under field conditions in Adana, Türkiye. The sesame genotypes varied widely in their fatty acid, lignan and tocol compositions. The content of palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, α-tocopherol, γ-tocopherol, α-tocotrienol, total tocopherol, sesamin, sesamolin, sesamol varied between 8.39-10.11%, 4.19-5.36%, 35.83-43.49%, 40.64-48.8%, 0.28-0.49%, 1.08-2.79 µg/g, 41.5-75.74 µg/g, 0.96-1.8 µg/g, 42.93-76.92 µg/g, 2.34-14.31 mg/g, 0.23-1.81 mg/g, 0-0.59 mg/g respectively. While the sesamin content of the sesame genotypes used in the study was higher than previously reported values, it was determined that the sesamol content was at very low levels. The sesame genotypes are rich in sesamin content and can be used as parents in breeding programs. Sesamol was not detected in almost all of the cultivars from Türkiye. In addition, it was determined that the γ-tocopherol contents of these cultivars were below the average value for Turkish cultivars. The same applies to sesamin and sesamolin. The results obtained from the study showed that the lignan and tocol composition of the cultivars produced in Türkiye were not at the desired levels.
An Enhanced Neural Network Forecasting System for the July Precipitation over the Middle-Lower Reaches of the Yangtze River
Authors: Liu Wenyan , Shi Xiangjun
Published: January 2025

Forecasting July precipitation using prophase winter sea surface temperature through a non-linear machine learning model remains challenging. Given the scarcity of observed samples and more attention should be paid to anomalous precipitation events, the shallow neural network (NN) and several improving techniques are employed to establish the statistical forecasting system. To enhance the stability of predicted precipitation, the final output precipitation is an ensemble of multiple NN models with optimal initial seeds. The precipitation data from anomalous years are amplified to focus on anomalous events than normal events. Some artificial samples are created based on the relevant background theory to mitigate the problem of insufficient sample size for model training. Sensitivity experiments indicate that the above techniques could improve the stability and interpretability of the forecasting system. Rolling forecasts further indicate that the forecasting system is robust and half of the anomalous events can be successfully predicted. These improving techniques used in this study can be applied not only to the precipitation over the middle-lower reaches of the Yangtze River but also to other climate events.
Ancient Chinese Architectural Modulus-Main Hall of the Erxian Temple at Jincheng
Authors: Xu Xiaogang
Published: January 2025

The original construction ruler (Yingzao chi) is calculated to be 29.939 centimetres long. It conforms to the long and short ruler system since the Tang and Song dynasties. Each ruler (1 chi) is 10 cun [寸], and each chi is divided into 12 small cun. The construction module was adopted. The basic modulus is 1 chi. 4 small cun is the infra - module, which is 1/3 of the basic modulus. 0.4 small cun is also an infra - module, which is 1/30 of the basic modulus. 30 cun is the multi - module, which is three times the basic modulus of 1 chi. This module is very similar to modern building modules. The building shape is in a proportional relationship under integer - size constraints.
A 34-Year Record of Seismic Activity at Vulcano Island, Italy
Authors: Falsaperla Susanna , Spampinato Salvatore , Cocina Ornella , Barreca Giovanni
Published: January 2025

Following the abrupt geochemical and geophysical variations that occurred on the island of Vulcano in September 2021, the search for previous multidisciplinary data on decades-long time spans became necessary to contextualize the newly recorded anomalous variations, which represented a serious threat for the local population. Our analyses of ‘vintage’ reports, old documents and analog seismograms broaden our understanding of crustal seismic activity. The results unravel the predominant role of the Vulcano’s hydrothermal system with respect to tectonic processes in the generation of seismicity in the analyzed sector. Earthquakes were generally located offshore and achieved a maximum M4.6. A 3D strain release map and DBSCAN application highlight seismogenic volumes to NW, SW, E offshore the island and trending NNW-SSE inshore, in agreement with structural pattern. Two major volcano unrests in 1985 and 1988 had seismicity mostly confined to the island. In comparison, the longer duration and typology of seismic signals recorded between 2021 and 2022 make this latest episode peculiar in the context of Vulcano’s past seismic activity.

Authors: Art Maşide , Ari Emrah
Published: January 2025

Background and Objectives: Data on the prognosis of hypercapnic respiratory failure (HRF) are limited, despite existing studies focusing on its causes and association with mortality. This study aimed to evaluate prognostic factors influencing long-term survival in patients with HRF due to chronic obstructive pulmonary disease (COPD) and to assess the effectiveness of the Age-adjusted Dyspnea, Eosinopenia, Consolidation, Acidemia and Atrial Fibrillation (A-DECAF) score. Materials and Methods: This retrospective study included patients admitted to the intensive care unit from the emergency department with HRF between April 2022-November 2023. Demographic data, comorbidities, laboratory results, and treatment protocols were recorded. A-DECAF scores were calculated, and survival was analyzed using Kaplan-Meier and ROC analysis. Results: Among 357 patients, 24.4% died within one year of discharge. Deceased patients had significantly higher mean ages (p<0.001) and higher APACHE-II, DECAF and A-DECAF scores (p<0.001). ROC analysis showed that A-DECAF had the highest sensitivity (93.1%) and accuracy (AUC=0.813) for predicting survival. Kaplan-Meier analysis indicated that higher A-DECAF scores were associated with reduced survival rates. Conclusion: The A-DECAF score is an effective tool for predicting long-term survival in COPD patients with HRF, particularly aiding clinical decisions in elderly populations. Further research is needed to validate its use in diverse patient groups.
Integrating Artificial Intelligence and Machine Learning in Cybersecurity for Financial Institutions
Authors: Wayz Wang
Published: January 2025

Financial institutions are increasingly adopting Artificial Intelligence (AI) and Machine Learning (ML) to bolster cybersecurity defenses amid growing threats in a rapidly digitized financial landscape. This integration leverages the predictive and adaptive capabilities of AI/ML to enhance threat detection, automate incident response, and mitigate risks in real-time. Traditional security measures often struggle to keep pace with evolving cyber threats, such as ransomware, phishing, and insider attacks. AI/ML models, trained on vast datasets, can identify anomalous behaviors, detect zero-day vulnerabilities, and proactively counter sophisticated attacks.In addition to strengthening operational security, these technologies enable financial institutions to comply with regulatory standards and reduce operational costs through automation. However, the integration also poses challenges, including data privacy concerns, adversarial attacks on ML systems, and the need for skilled personnel to manage and interpret AI/ML tools effectively.This paper explores the current state of AI/ML in cybersecurity for financial institutions, highlights real-world applications, and discusses future opportunities and challenges. By adopting a robust framework that combines AI/ML with traditional cybersecurity practices, financial institutions can achieve resilient, adaptive, and scalable security postures to safeguard sensitive data and maintain trust in a volatile threat environment.
Clinical Guideline for Detection and Management of Magnesium Deficiency in Ambulatory Care
Authors: Colaneri-Day Sherrie , Rosanoff Andrea
Published: January 2025

Background: Magnesium (Mg) deficiency is associated with many common chronic conditions and potentially severe health care outcomes, including cardiovascular disease, cardiovascular risk factors, and diabetes. However, Mg deficiency is underdiagnosed and often underrecognized in the ambulatory health care setting, and nutrition education and training are often limited for health care providers (HCPs). Methods: A clinical guideline for detecting and treating Mg deficiency in the ambulatory care setting was developed. A pilot study was conducted in which HCPs received education on Mg and completed pre-test and post-test questionnaires to assess intervention efficacy of the guideline. Results: Ten HCPs participated in the pilot study via telephone or face-to-face session. There was a statistically significant increase in general Mg knowledge among HCPs, due to the intervention of presentation of the guideline, with a nonsignificant increase in clinical practice. However, 1-month follow-up survey results showed that HPCs were likely to incorporate Mg assessment and treatment tools from the guideline in their future practice. Conclusions: These findings suggest that use of the proposed clinical guideline may increase HCP knowledge and improve the diagnosis and treatment of Mg deficiency.

Authors: Halma Matthew , Varon Joseph
Published: January 2025

Objective: This study introduces the Denominator-Adjusted Rate Estimates of Substance Adverse Events Frequency Evaluation (DARE-SAFE) method to analyze pharmacovigilance reporting rates for vaccines and common pharmaceuticals. Methods: We calculated reporting rates for the top 250 most prescribed drugs in the US FDA Adverse Event Reporting System (FAERS) and common vaccines in the Vaccine Adverse Events Reporting System (VAERS). For vaccines, we used CDC dose data and OpenVAERS reports. For pharmaceuticals, we utilized prescription data from ClinCalc and FAERS reports for 2022. Results: VAERS reporting rates varied significantly across vaccine types. COVID-19 vaccines showed a 63.0±0.6 times higher rate of VAERS deaths per dose and an 18.95±0.02 times higher rate of total adverse event reports compared to influenza vaccines. The ratio of total VAERS reports to deaths for vaccines was approximately 70:1 (R²=0.966). For pharmaceuticals, the ratio of total adverse event reports to deaths was about 43:1 (R²=0.697), with a strong correlation between serious adverse events and deaths (ratio 11:1, R²=0.768). Conclusion: DARE-SAFE provides a standardized method for comparing reporting rates across different medical products. The observed differences between vaccines and pharmaceuticals, as well as among different vaccine types, warrant further investigation into reporting practices, actual safety profiles, and potential biases in surveillance systems.

Published: January 2025

Ginsenosides with less sugar groups which were called minor ginsenosides might have greater pharmacological activity and a better adsorptive ability, but their content in nature is extremely low. In this study, a strain of Penicillium fimorum with strong saponin transformation ability was isolated from fresh Gastrodia elata. A comparative biotransformation experiment of the major saponins from Panax notoginseng root were conducted using crude enzyme from P. fimorum and commercial β-glucosidase to product minor ginsenosides. Specifically, the crude enzyme from P. fimorum was able to transform the major saponins from P. notoginseng root into 13 minor saponins within 72 hours, while commercial β-glucosidase was able to transform the same major saponins into 15 minor saponins within 72 hours. The most significant difference between their two enzymes is the ability to transform Rb1. To the best of our knowledge, the biotransformation ability of crude enzyme from P. fimorum is reported for the first time. These two enzymes have the potential to improve the economic value of P. notoginseng root and expand the methods for preparing minor saponins by transforming the major saponins in the total saponins of P. notoginseng root.
The Structure Determination of Tegoprazan((S)-4-((5,7-difluorochroman-4-yl)oxy)-N,N,2-trimethyl-1H-benzo[d]imidazole-6-formamide) Polymorphs A and B by Laboratory X-Ray Powder Diffraction

Published: January 2025

Tegoprazan is a potassium ion-competitive acid blocker (P-CAB) and novel inhibitor of gastric acid secretion. The crystal is available in two polymorphs, A and B, but their crystal structures have not yet been reported. Liquid and solid-state NMR were used to investigate the tautomeric state, which was found to be identical in both phases. Using these tautomers, the crystal structures of both polymorphs were determined from the X-ray diffraction data obtained with a laboratory powder X-ray diffractometer, employing simulated annealing and Rietveld refinement. It was found that both phases crystallized in the monoclinic space group P21, Z = 4, with the asymmetric unit containing two symmetrically independent molecules.

Published: January 2025

Background: Diabetic neuropathy (DN) is the most prevalent complication of diabetes, impacting up to 60% of people with diabetes. It is characterized by distal symmetrical loss of sensory function in the lower extremities, presenting with spontaneous excruciating neuropathic pain, hyperalgesia, and allodynia that impairs quality of life. The current work aims to evaluate the neuroprotective potential of naringin (a citrus flavonoid) and examine its ability to improve STZ-induced diabetic neuropathic pain by investigating its hypoglycemic, hypolipidemic, antioxidant, and anti-inflammatory effects. Methods: out of 40 adult male Sprague-Dawley rats, diabetes was induced in 30 rats by a single injection of STZ (45 mg/kg dissolved in citrate buffer). Ten days after induction of diabetes, rats were divided into four groups (10/group): normal control, diabetic control, naringin-treated diabetic rats, and glimepiride-treated diabetic rats as a positive control group. At the end of the experiment, serum and brain tissue samples will be collected then the hypoglycemic, lipid-lowering, antioxidant, and anti-inflammatory effects of naringin will be assessed and compared with that of glimepiride (a standard antidiabetic drug). Hyperalgesia and the effect of the studied drugs on it will also be evaluated by observing pain related behaviors in diabetic rats using hot plate, tail immersion, and mechanical sensitivity (von Frey) tests. Results: Significant increase in the serum levels of glucose, tri-glyceride (TG), total cholesterol (t‐cholesterol), low‐density lipoprotein‐cholesterol (LDL-C), and nitric oxide (NO), with a concomitant decrease in body weight (BW), plasma insulin and high‐density lipoprotein‐cholesterol (HDL-C) were observed in diabetic rats. Also, the brain level of malondialdehyde (MDA) was increased, while that of reduced glutathione (GSH), glutathione peroxidase (Gpx), superoxide dismutase (SOD), and catalase (CAT) were markedly decreased. Furthermore, diabetic rats showed a marked increase in plasma levels of proinflammatory cytokines including interleukin‐6 (IL-6) and tumor necrosis factor‐α (TNF-α). Moreover, hot plate, tail immersion, and von Frey tests revealed hyperalgesia in diabetic rats. Treatment with naringin and glimepiride reduced pain hypersensitivity, restored body weight and nearly normalized the altered biochemical parameters, more significantly with naringin than with glimepiride. Conclusion: These results may highlight the potential effects of naringin as a therapeutic strategy for diabetes and its complications including peripheral neuropathy.

Published: January 2025

Chronic urinary tract infection (UTI) presents with protracted lower urinary tract symptoms and elevated urinary leukocyte counts, but its bacterial etiological agents remain obscure. In this cross-sectional investigation, we aimed to unravel the role of the bladder microbiota in chronic UTI pathogenesis by studying the host immune response. Full-void urine samples were collected from healthy controls (HT), chronic UTI patients who had not initiated treatment (PT) and those undergoing treatment (OT), then sorted into white blood cell (WBC) and epithelial cell (EPC) fractions. Bacteria associated with both fractions were identified by chromogenic agar culture coupled with mass spectrometry and 16S rRNA sequencing. Distinct WBC-exclusive bacteria were observed in health, but this pattern was less obvious in patients, plausibly due to epithelial shedding and breaching of the urothelial barrier. We also described a bacterial fingerprint guided by Escherichia that was able to stratify patients based on symptom severity. Clustering analyses of mean rank changes revealed highly statistically significant upward and downward ecological shifts in communities of bacteria between health and disease. Interestingly, many of the most abundant genera identified in sequencing remained stable when compared between the study cohorts. We concluded that reshuffling of the urinary microbiome, rather than the activity of a single known urinary pathogen, could drive chronic UTI.

Abstract: This study aims to determine the effect of implementing Buddhism-based character education on the strengthening of religious moderation of Buddhist students in public high schools in one of the districts of North Lombok, West Nusa Tenggara Province. The problems that occur to students are making religious differences a trigger for conflicts and fights at school, making religion a joke, which has the potential to offend their friends, and lacking understanding and appreciation for religious diversity so that they are quickly involved in intolerant behavior, being influenced by a hostile environment, thus strengthening intolerant attitudes towards religious differences, feeling that their religion is superior, therefore underestimating other faiths. This study uses a quantitative approach with a survey method. The population in the study is 10th, 11th, and 12th-grade students with a total of 128 people; the sample in this study is 97 people, and the Proportional Random Sampling technique obtained the sample. The results showed a positive and significant influence between Buddhist religious education character-based and religious moderation, with a count of 14.547 and a significance value (p) of 0.000 < 0.05. From the results of simple regression analysis, the R Square value was obtained at 0.690. This means that Buddhist religious education character-based affects religious moderation by 69%, and factors outside this research model influence the remaining 31%. Based on the results, the school should be able to develop religious education with character to strengthen religious moderation in the daily lives of students, the school environment, and the community.

Penelitian bertujuan untuk mendeskripsikan rerata panjang ujaran dan pemerolehan fonologis yang diujarkan pada anak usia 2 tahun 1 bulan. Data dalam penelitian ini diperoleh dengan melakukan observasi terhadap ujaran yang diucapkan oleh anak BTS pada periode 1 bulan. Observasi dilakukan dengan pengamatan mendalam dan merekam ujaran. Data diperoleh saat anak BTS berbicara dengan memberikan stimulus dan wawanacara sederhana. Metode yang digunakan dalam memperoleh data adalah dengan metode simak libat cakap dengan pendekatan kualitatif. Analisis dilakukan dengan mentranskripsikan ujaran untuk dihitung jumlah kata setiap ujaran. Data kemudian dianalisis berdasarkan kemampuan penguasaan bunyi. Temuan dari penelitian ini adalah rerata panjang ujaran anak BTS adalah di atas rata-rata anak seusianya, tetapi ciri-ciri perkembangan bahasanya tidak sesuai dengan kelompok rerata panjang ujaran yang didapatkan. Dari segi fonologis, seluruh bunyi vokal telah dikuasai oleh anak BTS. Akan tetapi, bunyi konsonan anak BTS agak berbeda dengan perkembangan fonologis anak seusianya. Bunyi [r] umumnya mulai diujarkan pada tahap akhir hampir bersamaan dengan bunyi [x] dan [z], tetapi anak BTS telah menguasai bunyi [r] di semua posisi. Anak BTS justru belum sempurna mengujarkan bunyi [b] dan [s] yang seharusnya pada anak seusianya telah dikuasai secara sempurna. Oleh karena itu, perkembangan fonologis anak BTS tidak begitu sejalan dengan universalitas perkembangan fonologis anak.
