Effects of Cention N® restorations on buccal cytogenotoxicity and salivary oxidative stress in children with dental caries

Cention N ® is an alkasite-based restorative dental material containing methacrylate monomers and ion‑releasing alkaline fillers that liberate calcium and fluoride, components that have been implicated in oxidative stress (OS) and potential DNA damage in oral epithelial tissues....

First-child desire, preferred timing of first birth, and preference not to have children among nulliparous women in Peru: evidence from 20 ENDES rounds (2005–2024)

Fertility decline in Latin America suggests that an increasing share of the reduction occurs before the first birth. In Peru, population-level evidence on trends in first-child desire, reproductive indecision, and preferred timing of first birth among nulliparous women remains sc...

In Saccharomyces cerevisiae ΔRIB1 and ΔRIB4 mutants, riboflavin auxotrophy is reverted by Wolbachia (wStr) infection

In endosymbiosis, unicellular organisms, mostly prokaryotes, live inside the cells of a host that may be uni- or multicellular. More than half insect and arthropod species host the obligate endosymbiont Wolbachia spp., an alpha-proteobacterium that, given time, may coevolve with...

Sustainable production of poly(3-hydroxybutyrate) by Bacillus megaterium ATCC 14581: Kinetic and stoichiometric parameters of fed-batch production, ultrasound-assisted recovery, and characterization

The growing demand for bio-based materials has stimulated the development of sustainable alternatives to conventional plastics, among which polyhydroxyalkanoates (PHAs) stand out due to their biodegradability and biocompatibility. In this context, the present study evaluated the...

Navigating context and complexity: pedagogical insights from environmental assessment teaching

Teaching Environmental Assessment (EA) in higher education is both challenging and essential, given its applied, interdisciplinary nature and close connection to evolving practice. While previous studies highlight recurring challenges in EA teaching, such as dispersed course stru...

Drying Method Selection as a Critical Determinant of Pharmaceutical Quality in Biotherapeutic Lucilia sericata Larval Extracts

Objectives: This study aimed to compare the preservation efficacy of protein content and antioxidant activity in crude whole-body larval extract (WBE) products obtained from Lucilia sericata second instar (L2) larvae using four different drying protocols. Methods: The larvae were...

Psychological effects of temporal landmarks: A meta-analysis of affective, cognitive, and self-regulatory processes

Temporal landmarks, distinct time points that may shape affect, cognition, and self-regulatory behavior, have effects whose magnitude and boundaries remain uncertain. This meta-analysis systematically synthesized findings on the psychological outcomes linked to temporal landmarks...

Black phosphorus quantum dots for resistome mitigation: Mechanistic insights and rational engineering

The emergence of antibiotic resistance as a global environmental challenge has intensified the need for advanced strategies capable of addressing antibiotic contamination while reducing the environmental drivers of resistance dissemination. Although black phosphorus quantum dot (...

Shipping noise may trigger valve closure responses in exploited scallop beds of the Gulf of St. Lawrence

Shipping noise is a pervasive form of underwater noise pollution, yet its effects on benthic invertebrates remain poorly integrated into spatial risk assessments. The Atlantic sea scallop (Placopecten magellanicus), a benthic bivalve supporting the world's largest wild pectinid f...

System-level frequency stability enhancement in solar PV-dominated low-inertia power systems using robust nonlinear control

The rapid integration of inverter-based resources (IBRs) is changing the dynamic behaviour of modern power systems. As synchronous generators are replaced by photovoltaic (PV) inverters, system inertia decreases and frequency stability becomes more difficult to maintain. This pap...

Nanomaterials in food: From functional applications to toxicological outcomes–A review

Nanotechnology is a game-changing technology for food processing, preserving, packaging, and food fortification. Utilization of nanomaterials like organic, inorganic and hybrid composites has emerged as a promising method to improve nutritional bioavailability, shelf life, sensor...

Artificial intelligence in cellular senescence research: a systematic review assessing methodological quality and reporting standards using PROBAST + AI and TRIPOD + AI

Cellular senescence is a fundamental mechanism of biological ageing that has emerged as a critical target for therapeutic intervention in age related diseases. The coalesce of artificial intelligence and senescence research provides unprecedented opportunities in advancing our kn...

Tracking demographic shifts and epidemiological transition across 44 Asian countries from 1991 to 2023

This study investigates the intertwined demographic and epidemiological transitions across Asia’s five regions and empirically examines the association of demographic shifts on the epidemiological transition across 44 Asian nations. Data from 44 Asian nations from 1991 to 2023 wa...

Enhancement of mechanical characteristics of glass fiber composite by reinforcement of boron nitride and graphene oxide nanosheets

Glass fiber composites (GFCs) have garnered significant attention owing to their outstanding properties, such as low density, high strength, and flexibility, making them suitable for advanced aerospace applications. Enhancing their mechanical performance is vital to expand their...

Serum CEA, CA 19 − 9, and FDG PET/CT SUVmax in relation to histological subtype and overall survival in stage IV lung cancer

This retrospective study investigated the association of serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19 − 9 (CA 19 − 9) levels with 18 F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) findings, histological subtype, and overall...

A circular carbon fiber composite architecture enabled by synergistic multi-dynamic networks

The pervasive use of carbon fiber-reinforced epoxy (CFRE) laminates in aerospace and marine engineering is hindered by the permanent nature of conventional thermoset matrices, which precludes self-healing and end-of-life circularity. Furthermore, suboptimal interfacial bonding be...

Effect of abrasive flow machining (AFM) process parameters on surface roughness of AlSi10Mg parts produced with direct metal laser sintering (DMLS)

This study investigates the surface improvement of Direct Metal Laser Sintering (DMLS) produced AlSi10Mg alloy using Abrasive Flow Machining (AFM). Due to the layer by layer manufacturing mechanism, DMLS components typically exhibit high surface roughness, partially fused particl...

Dopamine D2/3 receptors and functional connectivity during fear extinction: A PET-fMRI study

Background The ability to learn what is dangerous in the environment and what no longer exerts a threat is essential for survival. The latter process is studied using Pavlovian fear extinction, the repeated presentation of a feared stimulus that gradually attenuates the fear resp...

A graph-based geospatial framework for delineating neighborhood planning units with barrier-aware isochrones

Graph-based GIS workflow is a relevant tool to urban planning and governance, yet most operational accessibility tools still rely on flat or Euclidean representations which can overestimate local dynamics in cities shaped by complex topography and fragmented urban forms. This lim...

Post-pandemic changes in recreational destinations: The impact of hiking tourism on three Czech case study regions

Since the outbreak of COVID-19, a noticeable portion of the tourism flows have shifted from urban destinations to nature-based tourism destinations. The increased number of hikers to such regions, which manifests in a new form of overtourism, exerts pressure on the sensitive land...
