Quinones as Optical Signal Transducers: Emerging Roles in Spectroscopic Sensing, Carbon Dots, and Enzyme-Free Immunoassays

Quinones have emerged as versatile optical signal transducers in spectroscopic analytical chemistry because of their unique redox activity, electron-transfer capability, reactive oxygen species generation, and tunable photophysical properties. Beyond their traditional roles as bi...

Thraustochytrids from the Red Sea mangroves in Egypt and their abilities to produce Omega-3 fatty acids

Forty-one isolates of the genus Aurantiochytrium were cultured from 32 samples collected from the Red Sea mangroves, Egypt. Cultured thraustochytrids isolated from: decaying leaves of Avicennia marina (34 isolates), decaying pneumatophores of A. marina (3 isolates), and decaying...

Empowering Memorable Tourism Experiences: How Smart Tourism Technology Quality Shapes Destination Perceptions and Tourist Psychological Empowerment

Smart tourism technologies are increasingly transforming how tourists interact with destinations, yet the mechanisms through which technology quality contributes to memorable tourism experiences remain insufficiently understood. Drawing on Stimulus–Organism–Response (S-O-R) theor...

Thriving with AI: How Employee AI Readiness Translates into Sustainable Work Behavior Through Service Innovation in Hospitality and Tourism Industry

Artificial intelligence is fundamentally reshaping work in hospitality and tourism, yet limited research has examined how employees’ AI readiness is associated with psychological and behavioral outcomes with sustainability implications. Drawing on Conservation of Resources Theory...

A novel repurposing opportunity for valsartan: angiotensin II type 1 receptor blockade dampens muscle-to-brain sensitization in fibromyalgia by targeting lncRNA H19/miR-29a-3p, inflammatory mediators, AKT/CREB signaling, neurotrophic factors, and amyloid–Tau pathology

Fibromyalgia (FM) is a debilitating nociplastic pain disorder increasingly recognized to involve skeletal muscle as an active contributor to peripheral nociception and central sensitization rather than a passive target of disease. Although angiotensin II promotes pain signaling t...

Rethinking satisfaction metrics: from online reviews to holistic experience analytics

Purpose The present study aims to question the trend of relying heavily on online reviews as the primary indicator of customer satisfaction in the hotel industry, exposes the disadvantages of the suggested strategy and suggests a more credible and multifaceted approach as an alte...

Beyond self-reports: the neuro-service quality (NSQ) framework

Purpose The paper is a critical reflection on the prevalence of self-report in the research on the quality of hospitality service and offers a new, neuro-scientifically based framework: neuro-service quality (NSQ). It is intended to solve the validity crisis in conventional surve...

Performance signature of high speed data processing radio over fiber system based fiber to home network applications with advanced quadrature amplitude modulation scheme

Abstract This paper has demonstrated the simulative study based on the performance signature of high speed data processing radio over fiber system based fiber to home network applications with advanced quadrature amplitude modulation scheme. Return to zero code (RZ) and nonreturn...

Electrophysiological responses in relation to speech perception in children with cochlear implants

Abstract Background Speech perception is a critical outcome of pediatric cochlear implantation, reflecting the effectiveness of auditory signal transmission and cortical processing for functional communication. Objective electrophysiological measures may provide valuable insight...

Turning social concerns into entrepreneurial intentions: unpacking the role of social entrepreneurship in emerging economies

Purpose This study examines how social entrepreneurship influences social entrepreneurial intentions among university students in a developing economy. It explores the sequential mediating roles of entrepreneurial attitude and entrepreneurial motivation, as well as the moderating...

Detoxification of aflatoxin M1 by eight lactic acid bacteria strains, alone or in combination, as viable and heat-killed cells in PBS, MRS broth, and Karish cheese

Abstract Aflatoxin M1 (AFM1) in milk is a major public health concern. It is a hydroxylated metabolite of aflatoxin B1 (AFB1), formed in the liver of animals after ingestion of contaminated feed and subsequently excreted into milk. Biological techniques could be used to combat th...
