Sexual Relationship Decision Making Based on Entertainment Media: A Qualitative Perspective Among Young Couples
Decision-making; Entertainment education; Netflix; Sexual health; Sexual intimacy; Young adults
As important as physical, mental, or social health is sexual health. Teenage pregnancy, STDs/STIs, and unsafe abortions are just a few of the population health issues that can arise from the absence of adequate sex education for young people. The purpose of this study is to investigate the process of sexual decision-making as influenced by media intervention among couples. Entertainment education (EE) is an approach that uses storytelling to influence large-scale behaviour change. EE has been used as a potent tool to educate, enlighten, and influence society and individual behaviour change worldwide. Through entertainment education, people have been taught about themes like HIV, family planning, pregnancy and child health, violence against women, and other subjects. Web series or movies that are accessible on the online subscription service, Netflix was taken into consideration for this study. Although there is a great deal of research on adolescent sexuality, studies of sexual decision-making have traditionally been gendered, meaning that men and women have been examined separately. This study is designed for a qualitative investigation using a phenomenological approach. Thematic analysis was employed to analyse semi-structured interviews of couples in a heterosexual romantic relationship. The findings will reveal the influence of entertainment education on young couples choices in their intimate relationships. 2024, The Author(s), under exclusive licence to Springer Nature Switzerland AG.

Comparative Analysis of Machine Learning Algorithms for Effective Crop Recommendation
AI in Farming; Crop Recommendation; Machine Learning; Precision Agriculture; Soil Analysis
The global call for sustainable farming necessitates a move away from traditional crop selection methods. These conventional approaches, often relying on farmer intuition, are imprecise and scale poorly in the face of complex environmental variables. Machine Learning (ML) models offer a robust, data-driven solution. By analyzing multifaceted data-spanning soil chemistry, weather patterns, precipitation trends, and historical yield performance-ML models can significantly enhance decision-making, optimize resource utilization, and improve overall crop outcomes. This paper delivers an extensive comparative review of key ML algorithms employed for crop recommendation, including Decision Trees (DT), Random Forests (RF), Support Vector Machines (SVM), k-Nearest Neighbors (KNN), and Artificial Neural Networks (ANN). We also explore the critical role of Explainable AI (XAI) in building model transparency. Our study evaluates these models on the metrics of accuracy, interpretability, and computational overhead. The research also investigates hybrid methods that integrate deep learning with conventional ML to enhance predictive power. Our comparative findings highlight the strengths and weaknesses of each model, concluding that ANN and XAI-based approaches demonstrate the highest accuracy and adaptability for diverse agricultural conditions. We also identify significant challenges, such as data imbalances and the absence of real-time data, and discuss future trends like the integration of IoT, remote sensing, and federated learning, which will be key to making precision farming scalable and accessible. 2025 IEEE.

chronic disease management; cloud computing; DHT11; elderly care; ESP8266; Internet of Things (IoT); MAX30102; MPU6050; real-time health analytics; remote patient monitoring; rule-based AI; wearable health monitoring
The growth in demand for remote and prolonged healthcare monitoring has led to a strong growth in adoption of wearable technologies and Internet of Things -based solutions. These technologies are meant to help solve real-time health supervision challenges, particularly for older adults and those suffering from long-term conditions, through reduced need for constant onsite medical care. Here, we describe the design and deployment of an intelligent health monitoring system that utilizes low-cost sensors and wireless communication to enable real-time, continuous monitoring of important physiological and environmental parameters. The suggested system combines an array of sensors: the DHT11 sensor to measure environmental temperature and humidity, the MAX30102 sensor for heart rate and SpO2 monitoring in real-time, and the MPU6050 sensor to sense body posture, orientation, and motion. The sensors are connected to an ESP8266 Wi-Fi MCU, which serves as the hub node for data sensing and transmission. Sensor data that is aggregated is processed locally and then sent to a cloud-based platform for analysis, storage, and visualization. To improve the functionality of the system, the system utilizes a cloud-hosted rule-based Artificial Intelligence (AI) engine for interpreting physiological patterns, identifying signs of abnormal health conditions at an early stage, and offering context-aware, personalized health suggestions. The platform provides dual output modes for added accessibility and reliability: an OLED display for local feedback, and an offdevice cloud dashboard for caregivers and health workers to view patients in real time. This study demonstrates the potential for the integration of embedded systems, cloud computing, and light AI methods to make predictive health analytics and facilitate proactive healthcare interventions possible. Through emphasizing modular design, low power, and scalability, the system is particularly suitable for deployment in elderly care, post-surgery recovery, and chronic disease management. Experimental assessments suggest that the system offers a credible, cost-efficient alternative. 2025 IEEE.

Biocidal activities of nickel oxide nanoparticles modified by copper and manganese, synthesized by green process
antimicrobial and anticancer properties; copper and manganese; NiO; Trigonella foenum-graecum
In recent years, the development of dual dopant-based nanoparticles (NPs) has gained significant attention as they possess exceptional physico-chemical and biomedical properties, making them potential candidates for antimicrobial and anticancer uses. In this research, we successfully synthesized nickel oxide (NiO) and copper, manganese-doped NiO (CuMn:NiO) NPs using a green synthesis method. The synthesis process involved Trigonella foenum-graecum (T.f.graecum) leaves extract as a nucleating agent. The synthesized nanoparticles were confirmed by various physico-chemical studies. Based on X-ray diffraction analysis, the median size was determined as 36 nm for NiO and 32 nm for CuMn:NiO NPs. The antibacterial study revealed that CuMn:NiO NPs exhibited a higher zone of inhibition in contrast to both Gram-positive (Streptococcus pneumoniae, Bacillus subtilis, Bacillus megaterium) and Gram-negative bacteria (Klebsiella pneumoniae, Escherichia coli, Vibrio cholerae) compared with NiO NPs and commercial amoxicillin. The antifungal studies conducted against Candida albicans demonstrated that CuMn:NiO NPs exhibited enhanced efficacy in comparison to NiO NPs. In vitro testing against human breast cancer cells (MCF-7) demonstrated the anticancer potential of NiO and CuMn:NiO NPs, supported by IC50 concentrations of 11 and 9?g/mL, respectively. The photoluminescence (PL) spectra of NiO and CuMn:NiO NPs exhibited a green emission at 508 and 518 nm, respectively, which indicated the generation of active free radicals by the NPs. These findings suggest that CuMn:NiO NPs hold promise in the healthcare industry. 2024 John Wiley & Sons Ltd.

The green synthesis of metal oxide nanoparticles (NPs) has garnered considerable attention from researchers due to its utilization of eco-friendly solvents during synthesis and cost-effective approaches. This study focuses on the synthesis of titanium oxide (TiO2) and dopamine (DA) carboxymethyl cellulose (CMC)-doped TiO2 (DA/CMC/TiO2) NP using Psidium guajava leaf extract, while also investigating the structural, optical, and morphological and biocidal potential of the prepared NPs. Significantly larger zones of inhibition were observed for DA/CMC/TiO2 NPs compared to TiO2 against various pathogens. Moreover, the MTT assay was carried out to evaluate the anticancer activity of the prepared samples against MG-63 cells, and the results revealed that DA/CMC/TiO2 NPs exhibited significantly higher level of anticancer activity compared to TiO2. The experimental results demonstrated that DA/CMC/TiO2 NPs exhibited enhanced anticancer activity in a dose-dependent manner when compared to TiO2 NPs. 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

Carboplatin-loaded zeolitic imidazolate framework-8: Induction of antiproliferative activity and apoptosis in breast cancer cell
breast cancer; cell death; cytotoxicity; drug delivery; pH sensitive
The challenge with breast cancer is its ongoing high prevalence and difficulties in early detection and access to effective care. A solution lies in creating tailored metalorganic frameworks to encapsulate anticancer drugs, enabling precise and targeted treatment with less adverse effects and improved effectiveness. Zeolitic imidazolate framework-8 (ZIF-8) and carboplatin (CP)-loaded ZIF-8 were synthesized and characterized using various analytical techniques. High Resolution-transmission electron microscopy of ZIF-8 and CP@ZIF-8 indicates that the particles had a spherical shape and were nanosized. The drug release rate of CP is 98% under an acidic medium (pH 5.5) because of the dissolution of ZIF-8 into its coordinating ions, whereas 35% in a physiological medium (pH 7.4) with the addition of CP, the high porosity, and pore diameter of ZIF-8 decrease from 1243 to 1041m2/g. Breast cancer MCF-7 cells were shown greater IC50 in CP@ZIF-8 (15.013.03g/mL) than free CP (34.984.25g/mL) in an in vitro cytotoxicity assessment. The cytotoxicity of the CP@ZIF-8 against MCF-7 cells was studied using the methylthiazolyldiphenyl-tetrazolium bromide method. The morphological changes were examined using fluorescent staining (acridine orangeethidium bromide and Hoechst 33258) methods. The comet assay assessed the DNA fragmentation (single-cell gel electrophoresis). The results from the study revealed that CP@ZIF-8 can be used in the treatment of breast cancer. 2024 International Union of Biochemistry and Molecular Biology, Inc.

Evaluation of Potential Toxicity of Calotropis gigantea Leaf Extract on Danio rerio: Bioactive Compounds, Oxidative Stress and Histological Toxicity Analysis
Calotropis gigantea; Histology; Oxidative Stress; Phytochemical Analysis; Zebrafish
A greater understanding of the ecotoxicological effects of plant-based products is required due to their increasing use. Despite its long-recognised medicinal properties, Calotropis gigantea possesses toxic characteristics that necessitate further investigation into its chemical composition and biological effects. This study evaluates the toxicity of crude C. gigantea leaf extracts on the freshwater fish Danio rerio over a 30-day exposure period. Alongside GCMS analysis, which identified 48 major constituents, the total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activity were assessed using the DPPH assay. The extracts exhibited a higher flavonoid content than phenolic content, indicating strong antioxidant potential. In contrast, biochemical analyses revealed that exposed fish showed significantly elevated levels of oxidative stress biomarkers, including succinate dehydrogenase (SDH), glutathione S-transferase (GST), glutathione reductase (GR), catalase (CAT), and superoxide dismutase (SOD), signifying cellular stress and disruption of redox homeostasis. Histological examinations of the liver, brain, muscle, and gills of treated fish demonstrated notable alterations. The gills exhibited lamellar fusion and epithelial lifting, impairing respiration. The brain showed neuronal vacuolation and degeneration, suggesting neurotoxicity, while muscle tissues displayed myofibrillar degeneration. Liver samples revealed hepatocyte necrosis and vacuolisation, indicative of metabolic dysfunction. Collectively, these enzymatic and systemic histopathological responses emphasise the toxicological impacts of C. gigantea extracts on aquatic organisms. The findings underscore the importance of ecotoxicological evaluations and the dual nature of medicinal plants such as C. gigantea, which can be both therapeutic and harmful. In addition to stressing the necessity for cautious application and further research to elucidate the mechanisms underlying their toxicity, this study provides valuable insights into the biological effects of plant-derived compounds. 2025, Dr Tarak Nath Podder Memorial Foundation.

Unveiling the Redox Characteristics of Rutin Trihydrate-Canvas-Based Sensor for Hydrazine Sensing in Water Samples
The inclusion of redox mediators into electrocatalytic systems facilitates rapid electron shuttling kinetics and boosts the overall catalytic performance of the electrode. This approach overcomes the sluggish reaction dynamics associated with direct electron transfer, which may be impeded by restricted analyte access to the electrodes active sites. In contrast to conventional synthetic redox mediators, naturally sourced phytomolecule rutin trihydrate (RT), extracted from apple juice, offers potential ecological advantages. This bands with green chemistry principles and sustainability in electroanalytical approaches. The current work presents an eco-friendly and direct electrochemical approach to fabricate a redox-active RT-immobilized MWCNT-infused PEDOT hybrid material-modified glassy carbon electrode (GCE/MWCNT + PEDOT@RT). The developed electrode showcased a sharp and stable redox signal at E0 = 0.63 V vs Ag/AgCl with no surface-fouling characteristics. The efficacious functionalization of RT onto MWCNT + PEDOT was corroborated by a remarkable increase in the surface characteristics, enhanced electrochemical current responses, and low charge transfer resistance. The GCE/MWCNT + PEDOT@RT exhibited highly selective and sensitive sensing responses toward the toxic and potentially carcinogenic hydrazine (HZ) via cyclic voltammetry and differential pulse voltammetry techniques, yielding a low detection limit (DL) of 1.02 ?M and a sensitivity of 0.032 ?A ?M-1 in a linear dynamic range between 0 and 1350 ?M. In addition, the method was highly efficient for HZ detection in real samples of tanker, tap, and wastewater samples, producing a good recovery of ?98%. 2025 American Chemical Society.

Advanced Machine Vision Paradigms for Medical Image Analysis
Computer vision and machine intelligence paradigms are prominent in the domain of medical image applications, including computer assisted diagnosis, image guided radiation therapy, landmark detection, imaging genomics, and brain connectomics. Medical image analysis and understanding are daunting tasks owing to the massive influx of multi-modal medical image data generated during routine clinal practice. Advanced computer vision and machine intelligence approaches have been employed in recent years in the field of image processing and computer vision. However, due to the unstructured nature of medical imaging data and the volume of data produced during routine clinical processes, the applicability of these meta-heuristic algorithms remains to be investigated. Advanced Machine Vision Paradigms for Medical Image Analysis presents an overview of how medical imaging data can be analyzed to provide better diagnosis and treatment of disease. Computer vision techniques can explore texture, shape, contour and prior knowledge along with contextual information, from image sequence and 3D/4D information which helps with better human understanding. Many powerful tools have been developed through image segmentation, machine learning, pattern classification, tracking, and reconstruction to surface much needed quantitative information not easily available through the analysis of trained human specialists. The aim of the book is for medical imaging professionals to acquire and interpret the data, and for computer vision professionals to learn how to provide enhanced medical information by using computer vision techniques. The ultimate objective is to benefit patients without adding to already high healthcare costs. 2020 Elsevier Inc. All rights reserved.

Phyto-Electrochemical Mapping of Indian Cappers: Redox Mediator Application on Mesoporous Carbon Based Electrodes
Indian Cappers (IC), often known for its wide range of applications as a medicinal plant, is an essential spice with phenolic phytochemical attributes. These are plausibly electrochemically redox active in nature. The redox moiety of phytochemicals can be exploited as a green route electron-transfer mediator, rather than conventional chemical redox mediators. Herein, mesoporous carbon-assisted electrochemical redox mapping of a phytochemical using IC plant is reported. A well-defined redox peak for IC-redox with E0 = 0.2 V is observed with a surface excess (?) value of 44.8 109 mol cm?2. Physico-chemical characterization is carried out to provide a detailed analysis of IC redox-based constituents. Furthermore, the fabricated IC sensor is used for the electrocatalytic oxidation of Ascorbic acid (AA) as a model system for preparing electrochemical sensors. The prepared sensor gave a notable oxidation peak for AA at E?= 220 mV with a sensitivity value of 0.0385 ?A/?M in the range of 0?1000 ?M. This work is a preliminary experiment for on-site testing of ascorbic acid in blood serum samples as a point of care testing. Additionally, the Cappers showed appreciable antibacterial activity against both Gram-positive and Gram-negative strains, producing clear inhibition zones even without the use of antibiotics. 2025 The Electrochemical Society (ECS).

Biosensing; cyclic voltammetry; electrocatalytic probe; electrode surface; plant-sourced; reactive sites; surface morphology; sustainable approach
The inclusion and interpretation of various phyto-based natural moieties embodying health gains is a critical and worthwhile scientific investigative focus. The descriptions comprehend their fundamental build-up, redox data, with significant electron shuttling, and strenuous obstacles in regard to the green-plant bioactives. Thus, a pressing and transformative undertaking toward simplistic electrocatalytic probe applications exploiting their reactive sites is a key focus, time demanding, or immediate call for top priority. Plant-sourced Basil or Subja seeds-redox entrapped within the mesoporous carbon spheres on a glassy carbon (GC) surface has been established (GC/graphitized mesoporous carbon [(GMC)@Subja] in this work. Unlike other established research constituting conventional approaches with limited access toward nonspecific or featureless voltammetric signals, we report a well-defined, sharp faradic response with an electrode potential E0' = 0.23 V (A1/C1) and 0.3 V (A2/C2) signals. The model Subja seeds-redox (GC/GMC@Subja) has been developed in an aqueous pH 7 phosphate buffer (PB) solution, contributing toward a sustainable and resilient strategy. This electrochemical methodology involved an underlying sp2-based mesoporous carbon framework for the ?-electron interaction and adsorption of the Subjaredox, leading to sp3 hybridization. The electrocatalytic function of GC/GMC@Subja showcased selective hydrazine (HZ) oxidation with a sensitivity and detection limit of 0.98 ?A mM-1 and 1.20 ?M (s/n = 3), respectively. Furthermore, the as-prepared system demonstrated HZ sensing in real samples with a recovery value of ?101.3%. 2026 IEEE.

Functionalized thiophenes are potential electroactive species that serve as efficient molecular electrochemical sensors. This work describes the fabrication of a 3-thiophene acetic acid (TAA)-modified screen-printed carbon electrode/multi-walled carbon nanotube (SPCE/MWCNT) platform via a facile electrochemical method in an aqueous medium. The effectual PT-Redox (product of TAA formed postpotentiostatic polarization) integration over SPCE/MWCNT was confirmed through various spectroscopic and electrochemical investigations. The SPCE/MWCNT showcased exceptional interaction with PT-Redox, creating a resilient platform for its precise binding, thereby enhancing the electrodeelectrolyte electroactive region, topographic roughness, electron conductivity, host response, and comprehensive electrochemical properties. The as-prepared electrode (SPCE/MWCNT@PT-Redox) was employed for the selective detection and quantification of glutathione (GT) as well as hydrazine (HyD) in an aqueous medium. The sensor showed excellent electrocatalytic oxidation responses toward these analytes, yielding a good sensitivity of 0.32 ?A mM1, a low detection limit (DL) of 0.225 ?M, a broad linear dynamic window of 0400 ?M for GT, a high sensitivity of 0.13 ?A mM1, a low DLof 0.56 ?M, and a linear window of 0350 ?M for HyD, obtained via the differential pulse voltammetry (DPV) technique. This substantiates that the modification with PT-Redox significantly boosted the electrodes interfacial activity and catalytic potential. Furthermore, the electrode exhibited robust antifouling and anti-interference traits, suggesting the composites enhanced stability and sensing capabilities for real-world applications. The captivating features, including excellent specificity, fast response dynamics, and simple sample preparation necessities of the proposed system, reveal a promising platform that accomplishes significant potential in futuristic sensing applications. 2025 American Chemical Society

Designing in situ nanostructured MWCNT-phloroglucinol modified webs for electrochemical-based dual screening of stress biomarkers
Phloroglucinol (PG), or benzene 1,3,5-triol, is an essential phenolic compound and a vital tannin. In this study, we developed a tannin-phloroglucinol (PG) derived redox mediator for the detection of glutathione (GT) and H2O2 on a glassy carbon electrode (GCE) modified with a multiwalled-chitosan composite. The PG redox platform was prepared using a cyclic voltammetric approach in pH 7 aqueous buffer media without any additional surfactant/chemical moieties. A highly stable, fouling-free surface confined redox characteristic was observed at an apparent electrode potential of E0? = ?0.196 V (A1/C1) and 0.05 V (A2/C2) vs. Ag/AgCl was observed. The as-prepared electrochemical platform achieved an ultra-low limit of detection (LOD) for glutathione (GT) of 0.16 M and LOQ of 2.08 M using a sustainable platform. In addition, it exhibited high selectivity for GT in the presence of various interfering analytes. In addition, the modified platform was extended to hydrogen peroxide (H2O2) sensing at ?0.196 V vs. Ag/AgCl with a LOD of 5.4 M in PBS buffer media at v = 10 mV s?1. The GCE/MWCNT-Chit@PG-Redox demonstrated robust performance in a proof-of-concept experiment for analyzing GT and H2O2 in real samples using a standard addition approach with good recovery values.

Dual drug co-encapsulation of bevacizumab and pemetrexed clocked polymeric nanoparticles improves antiproliferative activity and apoptosis induction in liver cancer cells
biomedical applications; drug delivery systems; nanoparticles, nanowires and nanocrystals
Nanoparticle (NP) enabled approaches have been employed for chemotherapeutic administration due to their capacity to regulate drug release and reduce side effects. Additionally, these methods can use several drugs concurrently and impede the proliferation of cancer cells that have developed resistance. Bevacizumab (BVZ) and pemetrexed (PEM) have demonstrated encouraging outcomes in the treatment and management of cancer. This work investigates the combined antiproliferative efficacy of BVZ and PEM co-loaded PLGA-PEG NPs (BVZ/PEM@PLGA-PEG NPs) against HepG2 liver cancerous cells. The BVZ/PEM@PLGA-PEG exhibited a sphere-shaped and consistent nanosized distribution. In addition, we evaluated the potential mechanisms for inhibiting cell growth and inducing apoptosis using DAPI staining and cell cycle study. The beneficial combined antiproliferative activity and the apoptosis pathway were detected in the HepG2 cells exposed to BVZ/PEM@PLGA-PEG NPs. Our study determined that the combinational drug treatment of BVZ/PEM@PLGA-PEG NPs has a significant effect on promoting the effectiveness of liver cancer treatment. 2024 Wiley Periodicals LLC.

Construction of Sorafenib Tosylate and Etoposide-loaded Liposomes: A Path to Precision Liver Cancer Therapy and its Apoptosis Induction
Cancer; Etoposide; Liposomes; Sorafenib tosylate; Synergism
Nanotechnology is an effective tool in fighting against cancer, playing a crucial role in investigating and fabricating novel anticancer drugs. Recognizing the worldwide prevalence of cancer, we combined sorafenib tosylate (ST) and etoposide (ETP) within liposomes. We assessed their ability to kill human umbilical vein endothelial cells (HUVECs) and HepG2 liver cancer cells. The liposomes effectively contained ST and ETP, exhibiting a particle size distribution below 180nm, a polydisperse index (PDI) below 0.2, a spherical shape, a strong negatively charged zeta potential, and encapsulation efficiencies of 59% for ST, 88% for ETP, and 57% for ST combined with 87% for ETP. The FTIR analysis indicates that the drugs were incorporated within liposomes. Encapsulation of the drugs in liposomes resulted in a more significant cytotoxic impact on HepG2 cells and a reduced cytotoxic impact on HUVECs. The morphological assessment of the HepG2 liver cancer cells was investigated using AO-EB and Hoechst 33258 staining methods. Apoptosis mechanisms of HepG2 cells were examined by Annexin V and PI dual staining. Furthermore, the coadministration of ST and ETP, which were enclosed in liposomes, resulted in a synergistic impact on the drugs, leading to cell death by apoptosis. 2024 Wiley-VCH GmbH.
