Active nuclease inhibition over passive freezing secures the genomic archive of fish eye lenses

Abstract Fish eye lenses offer a chronological archive of individual life histories and preserve genomic DNA. However, integrating ecological and genetic data is hindered by post‐mortem nuclease degradation, and standardized DNA preservation protocols for this tissue remain undef...

The Local Virial Theorem in Electron Localization Function Partitions

Abstract The local form of the virial theorem provides a stringent condition for assessing whether a spatial region behaves as a mechanically closed subsystem in molecular space. While basins derived from the topology of the electron density satisfy this condition by construction...

Gas-Phase Photocatalytic Nitrogen Conversion over Nanostructured Metal-Modified Fe2O3: The Role of Surface Chemistry, Band Alignment, and Hydrogen Activation

Abstract Photocatalytic nitrogen conversion over iron oxide-based materials remains challenging, particularly under gas-phase conditions, where reaction pathways and product distributions are poorly understood. Herein, nanostructured Fe2O3 and metal-modified Fe2O3 photocatalysts...

Environmental noise exposure partially accounts for the association between socioeconomic status and neural encoding of speech

Socioeconomic status (SES) has been associated with variability in neural speech encoding as indexed by the frequency-following response (FFR), yet the mechanisms underlying this association remain poorly understood. Environmental noise exposure represents a plausible pathway, gi...

Chronic Cortisol Exposure Reshapes Chromatin Accessibility and Gene Expression: Implications for Growth and Welfare in Rainbow Trout (Oncorhynchus mykiss)

Cortisol, the principal glucocorticoid in teleosts, coordinates the physiological response to stress by regulating metabolism, protein turnover, and growth. Although the molecular effects of acute cortisol exposure have been extensively characterized, the epigenomic mechanisms un...

Planar Tetracoordinate Hydrogen Stabilized Within Alkali Metal–Halogen Frameworks

A D 4h screening of the 25 H©M 4 X 4 − combinations (M = Li–Cs; X = F–At), followed by unbiased global‐minimum searches on the nine vibrationally stable candidates, reveals eight previously unreported planar tetracoordinate hydrogen (ptH) global minima adopting D 4h symmetry, bri...

Landmark-defined two-dimensional lung configuration in women with osteogenesis imperfecta type III: an exploratory geometric morphometric pilot study

Osteogenesis imperfecta (OI) type III is a rare disorder in which severe thoracic deformity may alter pulmonary anatomy. This exploratory pilot study assessed whether the relative two-dimensional configuration of four reproducible pulmonary landmarks differs between adult women w...

Horizontal mitochondrial transfer and mitochondrial transplantation in skin: protection against UVR-induced ROS damage and enhancement of cell proliferation and wound healing

Skin homeostasis, protection against ultraviolet radiation (UVR), and wound repair depend on coordinated interactions among melanocytes, keratinocytes, and fibroblasts. Horizontal mitochondrial transfer (HMT) is a naturally occurring form of intercellular communication in which m...

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds

Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,...

Athletic Performance after Complex Training Compared to Traditional Strength Training

Effects of ≥4‑week Complex Training (CT) in trained/developmental athletes (≥3×/week, local competition) are unclear. This review addressed this gap. Five databases were searched for RCTs (updated June 2025) comparing CT vs. traditional strength training on jump, agility, and spr...

A Hybrid Multi-Criteria Decision-Making Framework for Selecting the Most Suitable Photovoltaic Proposal in Healthcare Institutions

Reliable electricity supply is essential for healthcare institutions, particularly where grid instability can disrupt service continuity, compromise patient safety, and affect the operation of critical medical equipment. In this context, selecting an appropriate photovoltaic (PV)...

E2(η6–Be6H6) (E = Si–Pb): Doubly Aromatic Inverse-Sandwich Complexes

Abstract We report E2(η6-Be6H6) (E═Si, Ge, Sn, Pb), a new family of doubly aromatic inverse sandwich clusters in which a tetrel diatomic is sandwiched between a beryllium hydride ring. All four members adopt a singlet D6h global minimum, separated from the nearest competing isome...

Rare Diseases as Epistemic Objects: Exploring the Moral Role of Health Systems

ABSTRACT This article explores how rare diseases reveal the moral and epistemic foundations of healthcare systems. Based on narrative interviews with 11 Chilean patients and 10 professionals, this study shows how the absence of standardised protocols—such as clinical guidelines,...

Molecular investigation of tick-borne pathogens in Ixodes ricinus feeding on lizards in the Central Pyrenees, Spain

Abstract Ixodes ricinus is the most widespread tick species in Europe, parasitizing a broad range of vertebrate hosts, including reptiles. However, the role of lizards in the ecology of tick-borne pathogens remains poorly understood. This study investigated tick infestation level...

Effects of Zinc Supplementation on Glycemic Control, Insulin Resistance, Inflammation and Oxidative Stress in Diabetes: A Systematic Review and Meta‐Analysis of Randomized Controlled Trials

ABSTRACT Objectives Diabetes mellitus (DM) is a chronic metabolic disorder characterized by insulin resistance, impaired insulin secretion, and increased cardiometabolic and inflammatory burden. Zinc plays a key biological role in insulin synthesis, storage, signalling and antiox...

Gender gaps in education and labor, human-capital efficiency and inclusive regional growth in Chile

Purpose This study investigates whether reducing gender gaps in education and labor markets contributes to regional economic growth in Chile. It provides empirical evidence on the economic costs of gender inequality across the country's diverse sixteen regions, highlighting how t...

Impact of Spatial Knowledge on Fire Evacuation Performance in Large Buildings: An Integrated Simulation Approach

This study examines human evacuation performance in complex building environments under highly uncertain fire conditions, with a focus on how spatial knowledge and decision-making strategies influence exposure to hazardous conditions during emergencies in smart building contexts....

Structure and Spatio-Temporal Dynamics of Marine Communities Associated with the Kelp Forests at Cape Froward, Strait of Magellan

Giant kelp forests, Macrocystis pyrifera, dominate the coasts of southern Patagonia and are particularly abundant in the coastal ecosystems of Cape Froward, where they play a key role in biodiversity conservation and the provision of multiple ecosystem services, establishing them...

Lifestyle Medicine Competencies in Women’s Health: Consensus-Based Standards From the International Board of Lifestyle Medicine

Lifestyle medicine (LM) takes an evidence-based approach to the prevention and management of many conditions affecting women; however, no dedicated competency framework currently guides its application across the life span. We aimed to develop a comprehensive set of core competen...

Strategic responses to digital disruption: lessons from online business education in Chile

Purpose This paper provides a strategic and capability-based longitudinal analysis of the evolution of online undergraduate business education in Chile between 2012 and 2024. Rather than treating digital expansion as a purely technological shift, this study aims to examine how bu...
