aging population; geriatrics; healthcare; utilization; working elderly
Background: The elderly population of India has been growing exponentially over the past few decades, caused by a decline in fertility and an increase in life expectancy. The growth eventually has transcended the disease burden on the public healthcare system. This calls for a need to evaluate the healthcare utilization pattern of the elderly based on their socioeconomic and working condition. Methods: Study used access to public and private healthcare services to measure healthcare utilization. Descriptive analysis and multivariable logistic regression were used to understand utilization patterns by working status and some selected sociodemographic parameters. All the results were reported at a 95% confidence interval. Results: Using the data from the first wave of Longitudinal Ageing Study in India (LASI) with a sample of 22,680 older persons 60 years and above. The study identified that 50% of the working elderly access private services; however, 26% access public healthcare services. It was found that the working status of the elderly alone did not influence access to healthcare services, but education is also an essential indicator for utilizing healthcare services. Further, factors such as gender, marital status, religion, wealth, tobacco usage, self-rated health, ADL and IADL were significant predictors of healthcare services utilization for the elderly. Conclusion: This study suggests that there are not many differences found among working and non-working status with healthcare utilization, although some sociodemographic indicators are associated with the utilization of healthcare services, highlighting that increasing health needs among the elderly requires strengthening the quality and appropriate public investment in health. 2024 Taylor & Francis Group, LLC.

Exploring the challenges and prospects of healthcare reporting in Indias Hinterland
Bordering region; Health Disparity; Journalism; News Reporting
Differential access and utilisation of healthcare services are caused by multiple Social Determinants of Health (SDHs), which requires adequate and informed policy intervention. The mass media, mainly the news media, have been seen as a practical approach in communicating the health anomalies at the policy level. The comprehensive coverage of factors associated with the healthcare system can further lead to addressing inequalities in health. The study was aimed to identify the factors that act against effective reporting of healthcare news from peripheral regions of India. The qualitative method was employed to examine media professionals' persistent challenges and experiences in covering health-related disparities. Sixteen media professionals were interviewed during October 2019 employed in vernacular news agencies all across the north-eastern state of Assam, India. Three themes have emerged from the analysis covering health-related news and barriers to healthcare in the peripheral region and identifying health-related disparities. It is found that an effective reporting mechanism of the health news will positively influence the policymakers and undertake efforts to address the health-related disparities.

Involvement of chalcones and coumarins in environmental stress tolerance
Chalcone synthase; Coumarins; Environmental stress; Fungicide; Malondialdehyde; Scopoletin
Plants are invariably subjected to various environmental stresses that hinder their normal growth and development, which leads to decreased plant productivity and yield. To combat the detrimental effects of such abiotic and biotic stresses, plants have developed diverse mechanisms and one of the prominent ones includes the production of secondary metabolites like phenolic, alkaloids, terpenes, etc. Secondary metabolites serve as major components of the plant stress responses. Chalcones (1,3-diaryl-2-propen-1-one) and coumarins (1,2-benzopyrone) are precursors of flavonoids, a common secondary metabolite of plants that provide a beneficial role during oxidative and biotic stress. Apart from protection, coumarins have certain roles in promoting or inhibiting plant growth, affecting cell division and differentiation and auxin metabolism. These compounds are also known to possess therapeutic properties such as anti-inflammatory, anti-microbial, anti-cancer, and cytotoxic effects when isolated from plants. Besides, chalcones and coumarins have allelopathic effects and protect plants against herbivory. Owing to excellent ROS scavenging properties, chalcones, coumarins, and their derivatives are extensively employed as agents to alleviate adversities associated with abiotic stresses like osmotic, heat, and cold stress, and in defense against pathogen invasion. The application of these secondary metabolites to mitigate atrocities of environmental stress in plants is an interesting and concurrent area of investigation. This chapter highlights the structural and functional details of chalcones and coumarins and their implications in ameliorating environmental stress in plants. 2024 Apple Academic Press, Inc.

Sesquiterpenoid-rich Java Ginger rhizome extract prompts autophagic cell death in cervical cancer cell SiHa mainly by modulating cellular redox homeostasis
Cancer biology; Cell culture; Cytotoxicity; Flow cytometry; Western blot analysis
Java Ginger or Curcuma zanthorrhiza Roxb. has long gained focus among tribal people of Java, for its medicinal properties mainly against gynaecological challenges. The present study aims to identify the most potent phytocompound present in the extract and determine primary mode of action accountable for cytotoxic activity of Curcuma zanthorrhiza rhizome extract against HPV16-positive SiHa cervical cancer cells. The phytochemically-rich extract of rhizome (CZM) was capable to inhibit proliferation of target cells in a dose-dependent manner with an IC50 of 150?g/ml. Dysregulation of intercellular antioxidant defence system resulted to surges in ROS and RNS level, increased calcium concentration and compromised mitochondrial membrane potential. Nucleus got affected, cell cycle dynamics got impaired while clonogenicity and migration ability diminished. Expression of viral oncogenes E7 and E6 decreased significantly. Accumulation of toxic cell metabolite and decrease in level of essential ones continued. Finally, alteration in PI3K/AKT/mTOR signalling route was followed by onset of autophagic cell death concomitant with the upregulated expression of Beclin1, Atg5-12 and LC3II. Curcumin and a novel crystal as well as few phyto-fractions were isolated by column chromatography. Of these, curcumin was found to be most potent in inducing cytotoxicity in SiHa while two other fractions also showed significant activity. Thus, CZM acted against SiHa cells by inducing autophagy that commences in compliance to the changes in PI3K/AKT/mTOR pathway mainly in response to oxidative stress. To the best of our knowledge this is the first report of Curcuma zanthorrhiza Roxb. inducing autophagy. 2022, King Abdulaziz City for Science and Technology.

Photoluminescence studies of non-toxic monoclinic yttrium oxide quantum dots synthesized at low temperature for live cell imaging applications
Bioimaging; Intense blue emission; Low temperature; Non-toxic monoclinic yttrium oxide
Synthesis of monoclinic Y2O3 remains a challenging task due to complex formation conditions such as high pressure or high temperature environments. Monoclinic yttria exhibits better photoluminescence characteristics compared to the cubic phase and hence can be a better host for nanophosphors. Reports are available predicting the stability of monoclinic phase at low temperature in extremely fine particles. But experimental preparation of this phase at low temperature is not yet reported. Here we report the first-time preparation of monoclinic Y2O3 at 90 C using simple laboratory hot air oven. The synthesized nanoparticles exhibit intense PL emission in the blue region and hence can find applications in display industry. The band structure calculations were carried out using density functional theory and the excitonic Bohr radius was estimated using the electron as well as hole effective masses determined from band structure. The cytotoxicity studies reveal non-toxic nature the particles. The fluorescence imaging experiments show that the material is capable of emitting blue fluorescence in L6 skeletal cell lines and it ensures the applicability of this material in the biomedical field. 2022 Elsevier Ltd and Techna Group S.r.l.

Persistent Luminescence and in Vivo Bioimaging
In vivo imaging; Multimodal imaging; NIR fluorescent probes; Persistent luminescence; Upconversion
In vivo bioimaging encompasses the non-invasive visualization of internal cells or organs within the human body, facilitating the real-time monitoring of dynamic biological processes. This form of bioimaging holds paramount significance within clinical domains due to its capacity to facilitate early disease detection, notably in cases of life-threatening conditions such as cancer. Although established imaging modalities like ultrasound, magnetic resonance imaging, and fluorescence imaging exist, the quest for innovative imaging probes with enhanced visibility to provide high-resolution images remains an active area of research. The introduction of persistent luminescent nanoprobes, characterized by their unique afterglow luminescence property, presents an exciting avenue in the realm of bioimaging. These nanoprobes offer several advantages over traditional fluorescent probes, notably in their ability to surmount light attenuation challenges within biological tissues including issues such as autofluorescence and light scattering. The chapter offers a succinct introduction to two pivotal facets of fluorescence imaging, namely persistent luminescence and upconversion luminescence while elucidating the underlying mechanisms governing their luminescence behavior. Moreover, this chapter provides comprehensive insights into various fluorescence imaging techniques, encompassing near-infrared imaging, upconversion imaging, X-ray-activated luminescence imaging, persistent luminescence imaging, and various multimodal imaging techniques.

A critical review focussing on the synthesis and applications of monoclinic yttrium oxide nanophosphor
Applications; B-type Y2O3; Bioimaging; Photoluminescence; Synthesis Routes
Research on monoclinic Y2O3 has been limited, not because of a lack of potential applications, but rather due to challenges associated with synthesizing phase-pure material. The limited understanding of the material and its properties has hindered researchers from further exploring this compound. Some studies suggest that the B-type polymorph of Y2O3 exhibits superior performance compared to its cubic counterpart. Additionally, there are reports indicating the existence of simple synthesis techniques that could potentially overcome the material's significant disadvantage highlighted by many researchers, namely, complex synthesis routes. To date, no comprehensive reports have summarized the key findings related to B-type Y2O3. In this effort, we aim to provide an exhaustive overview of research conducted on this polymorph. This includes an examination of diverse synthesis techniques employed by researchers, theoretical studies conducted on the material, an exploration of its luminescence properties, and an overview of various applications studied thus far. 2024 Elsevier Ltd

cancer cell imaging; Eu doping; monoclinic yttria; PEG-folic acid capping; photoluminescence
Clinical applications of nanophosphors have gained extensive interest in research areas such as bioimaging and targeted drug delivery. The development of nontoxic semiconductor quantum dots (QDs), which can replace the conventional fluorescent probes, can bring significant developments in the bioimaging industry. This work reports the synthesis of monoclinic Y2O3:Eu QDs, without and with surface functionalization using PEG/folic acid at low temperature and its application in live cancer cell imaging. The synthesized quantum dots show sharp absorption in the short UV region and an intense red emission at 614 nm. Concentration-dependent optical properties are studied in detail, and color purity is measured. Transmission electron microscopy substantiates the monoclinic structure, crystalline nature, and the lower particle dimensions essential for the biological applications. The surface-modified sample is characterized for its structural and luminescence properties. Biocompatibility was ensured by performing MTT Assay on L6 skeletal muscle cell lines (normal) and MCF 7 cell lines (cancer) for the samples without and with surface modification, respectively. Fluorescence detection experiments on SKMEL cells using an uncapped sample prove the suitability of the material as a fluorescent probe. The effect of surface functionalization on imaging results was established by carrying out fluorescence detection experiments on MCF 7 cells using PEG-folic acid-functionalized sample, which resulted in enhanced cell uptake, specific binding, and bright fluorescence emission. Thus, this work authenticates the suitability of the material to be used as a reliable nanophosphor and an efficient fluorescent probe for imaging cancer cells. 2024 American Chemical Society.

Food innovation adoption and organic food consumerism-a cross national study between Malaysia and Hungary
Circular economy; Environmental concern; Food innovation adoption; Food security; Health consciousness; Organic foods consumerism
In order to meet the rising global demand for food and to ensure food security in line with the United Nations Sustainable Development Goal 2, technological advances have been introduced in the food production industry. The organic food industry has benefitted from advances in food technology and innovation. However, there remains skepticism regarding organic foods on the part of consumers, specifically on consumers acceptance of food innovation technologies used in the production of organic foods. This study measured factors that influence consumers food innovation adoption and subsequently their intention to purchase organic foods. We compared the organic foods purchase behavior of Malaysian and Hungarian consumers to examine differences between Asian and European consumers. The findings show food innovation adoption as the most crucial predictor for the intention to purchase organic foods in Hungary, while social lifestyle factor was the most influential in Malaysia. Other factors such as environmental concerns and health consciousness were also examined in relation to food innovation adoption and organic food consumerism. This paper discusses differences between European and Asian organic foods consumers and provides recommendations for stakeholders. 2021 by the authors. Licensee MDPI, Basel, Switzerland.

Comprehensive Study of Silver Nanoparticle Functionalization of Kalzhat Bentonite for Medical Application
bentonite; biomedical materials; montmorillonite; silver nanoparticles; surface modification
The characterization and biomedical modification of bentonite clays from the Kalzhat deposit (Kzh), which is situated in Kazakhstans Zhetysu region, are the main objectives of this work. In order to improve the raw materials structural qualities, the montmorillonite fraction was enriched, and coarse impurities were eliminated using the Salo method. The presence of meso- and micropores that guarantee high dispersity and specific surface area, as well as the prevalence of montmorillonite and kaolinite, was all confirmed by physicochemical analysis. Particle size measurements indicated finely dispersed structures with a propensity to aggregate, whereas thermal analysis demonstrated resilience under heating. After effective functionalization with silver nanoparticles, a porous hybrid system with improved surface reactivity was produced. These enhancements demonstrate the modified bentonites usefulness as a multifunctional carrier for the immobilization and controlled release of pharmaceuticals, with potential uses in drug delivery systems, antimicrobial coatings, and wound-healing materials. The material has potential use in sorption and environmental protection technologies in addition to its biomedical application. Overall, Kzhs structural and functional performance is greatly improved by the combination of purification and functionalization with silver nanoparticles, highlighting its promise as a useful element in the development of next-generation polymercomposite systems. 2025 by the authors.

Effectiveness of relationship education programs for premarital romantic and sexual relationships for adolescents and young adults: A systematic review
Adolescents; PRISMA; Relationship education programs; Romantic relationships; Systematic review; Young adults
Relationship Education Programs (REPs) have gained significant attention in recent years in Western cultures as a preventative approach to promoting healthy romantic and sexual relationships. These programs aim to provide individuals with the knowledge and skills necessary to build and maintain positive romantic and sexual relationships, and to reduce negative societal outcomes such as teenage pregnancy and single-parent households. This systematic review will provide a comprehensive analysis of the current literature on relationship education programs for pre-marital romantic and sexual relationships in terms of their effectiveness, various formats in which they are delivered, and outcome variables being studied. The findings show that the outcomes could be divided into seven categories: self improvement, knowledge acquisition, attitudinal changes, behavioral changes, psychological impacts, skill development, and changes in relational dynamics. It has been demonstrated that REPs are effective in knowledge and skill transfer for romantic relationships. Effectiveness testing was done using quasi-experimental designs, experimental studies with a control group, or randomized control trials. Most of the REP research was conducted in the USA; very few studies were obtained from other parts of the world. The effectiveness of REP, program characteristics, testing, gender differences etc. are also discussed. Springer Nature Singapore Pte Ltd. 2025. All rights reserved.

Electrochromism is the mutable change in optical properties of an electrochromic material caused by redox reactions due to the application of voltage. Easy intercalating the H + ions on a dense electrochromic material (WO3) is the most important parameter as far as the reaction kinetics is concerned. The goal of our work is to improve the electrochemical response of electrochromic material by constructing nano-pillars rather than using dense electrochromic materials. Electrochemical performance of both the dense (planar) and porus (nano pillars) structures were simulated and experimentally proved with a systematic discussion in the present work. It is proven and shown here the increase in the electrochemical kinetics through easy diffusion of ions into the nanostructured electrochromic material. 2022 Elsevier B.V.

On ion transport during the electrochemical reaction on plane and GLAD deposited WO3 thin films
Coloration efficiency; Diffusion coefficient; GLAD; Plane; Sputtering; Tungsten Oxide (WO3)
Tungsten oxide thin films were deposited on FTO and Corning glass substrates on Plane and GLAD (75) using DC magnetron sputtering and characterized using SEM, XRD, UVVis spectrophotometer, and Electrochemical analyzer systematically. Further, a comparative analysis was carried out in which it was observed that the result of surface morphology for plane showed the denser and GLAD showed nanopillars deposition. The amorphous nature of the sample was evident from XRD analysis. Optical transmittance was between 87% and 81% for both plane and GLAD. The Electrochemical studies showed the diffusion coefficient of H+ ions are more compared to Li+ ions for both plane and GLAD and Coloration efficiency was calculated at the scan rates of 10, 30, and 50 mV/s at the wavelength of 500 to 600 nm. 2021

Sputter deposited tungsten oxide thin films and nanopillars: Electrochromic perspective
Coloration efficiency; Glad; Partial pressures; Planar; Sputtering; Tungsten oxide (WO3)
Tungsten oxide (WO3) thin films and nano pillars were grown on FTO and corning substrates by using DC magnetron sputtering. Structural properties, surface morphology, optical properties, and electrochromic properties were systematically characterized by using SEM, XRD, UVVis Spectrometer, and Electrochemical Analyser respectively. Increased oxygen partial pressure resulted a rise in the optical transmittance from 72% to 89% at a wavelength of 600 nm. Moreover, coloration efficiency was also found to vary with partial pressures for both planar and glad from 30.48 cm2C-1 to 78.36 cm2C-1. We observe that glad deposited nano pillars showing higher coloration efficiency as compared to the planar thin film. The coloration efficiency found for the planar thin film and nano pillars at optimized partial pressure are 37.04 cm2C-1 and 78.36 cm2C-1 respectively. A strong influence of oxygen partial pressure and surface to volume ratio has been observed on the coloration efficiency, which can play a major role in the electrochromic application. 2022 Elsevier B.V.

Glancing angle sputter deposited tungsten trioxide (WO3) thin films for electrochromic applications
Coloration efficiency; Diffusion coefficient; Electrochromism; Glancing angle deposition; Transmittance; Tungsten oxide films
The columnar growth angle-dependent tungsten oxide (WO3) thin films were grown by using the Glancing angle sputter deposition (GLAD) technique with varying different substrate angles (00, 700, 750, and 800) on Fluorine-doped tin oxide (FTO) and Corning glass (CG) corning glass substrates at room temperature. The surface morphology, crystallographic structure, optical, and electrochemical properties were determined using X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM), UltravioletVisible(UVVis) spectrometer, and electrochemical analyzer, respectively. The structural properties reveal that the films are amorphous in nature. FE-SEM studies observed the columnar growth of the nano-rods and surface porosity. The optical transmittance of the deposited films was decreased from 83 to 78%, and the optical bandgap decreased from 3.08 to 2.88eV with increasing GLAD angle. The electrochemical studies reveal that the GLAD angle influenced the coloration efficiency (CE). The highest CE of 32cm2/C at 600nm and highest Diffusion coefficient (DC) of 6.529 109 cm2s?1 of the films was observed for the films deposited at an angle of 750. 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature.
