Close relationship and role of fractal dimension, heterogeneous nucleation, dynamic transformations and cooperativity mechanisms in unperturbed tumor growth

<title>Abstract</title> The cancer is the second leading cause of death worldwide and remains an enigma for researchers and medical doctors. The aim of this study is to propose a novel methodology that demonstrates the close relationship and role of fractal dimension, heterogeneo...

Exohedral 1:2Complexes of Lanthanide Atoms with theC60 Fullerene: What Hapticity Is Preferred, η10, η11, or η12?

Abstract The structure of crystalline lanthanide–C60 fullerides allows for the Ln atom coordination to two rings of adjacent fullerene molecules simultaneously, where the resulting Ln hapticity can be η10, η11, or η12. We analyze the geometries, bonding strength, charge, spin, an...

Curcumin Nanoemulsion: Characterization and Effect on Cataracts in an In Vivo Animal Model and Ex Vivo Human Model

Cataracts are the leading cause of reversible blindness worldwide; this condition results from the aggregation of lens proteins. Currently, surgery remains the only treatment; however, there is growing interest in non-surgical approaches, including the use of bioactive compounds...

An Agent-Based Model of the Stellar Mass Distribution

The Initial Mass Function (IMF) describes the distribution of stellar masses formed in a stellar cluster and constitutes a fundamental constraint for theories of star formation. In this work, we investigate the emergence of the IMF slope using a minimal agent-based model inspired...

Uneven progress in Alzheimer’s disease and other dementias across Mexico, 1990–2023: updated estimates from the Global Burden of Disease Study

Objectives To quantify the magnitude and trends the national and subnational burden of Alzheimer’s disease and other dementias (ADOD) in Mexico from 1990 to 2023, analyzing patterns by sex and age and exploring their association with the Socio-Demographic Index (SDI) and the Heal...

Association between risk of eating disorders and an unhealthy lifestyle score in university students: uniHcos project

Introduction The first year of university is a critical period for the consolidation of lifestyle habits and has been associated with an increased risk of developing eating disorders (EDs). This study aimed to assess the prevalence of ED risk among first-year Spanish university s...

Behavioural impact of microplastics on zebrafish development

Microplastic (MP) pollution in aquatic environments is ubiquitous and characterized by particles of highly irregular shapes. Yet, most laboratory studies examining MPs impacts on aquatic species rely on pristine polymer spheres, which poorly reflect the diversity and complexity o...

The Effect of SolvationSphere Composition on theNucleophilic Substitution Mechanism: The Hunt for the Elusive CarbocationIntermediate

Abstract Despite its ubiquity, the SN1 carbocation intermediate and its reaction profile have remained computationally elusive, owing to the sensitivity to the number of solvating molecules and the flat potential energy surface. The ionization step for solvolysis of tert-butyl ch...

Enhanced Photolysisand Photocatalysis Assisted byHydrodynamic Cavitation for the Removal of Methylene Blue Dye

Abstract This study investigates the synergistic integration of hydrodynamic cavitation (HC) with photolysis and photocatalysis to enhance the degradation of synthetic dyes in aqueous systems. Methylene blue (MB) is selected as a model pollutant, and tap water is used as the work...

Clinical Relevance of Bile Acid and Bile Acid-Related Therapy in Liver Cirrhosis: A Review

Cirrhosis, the end stage of various chronic liver diseases, is characterized by complex pathophysiologies and poor outcomes. Recently, dysregulation of bile acid metabolism has been increasingly recognized as a key factor in the development and progression of liver cirrhosis and...

The Zooplankton International Geospatial dataset: A global repository of spatiotemporal freshwater zooplankton community composition data from lakes and reservoirs to support ecological research

Abstract Zooplankton transfer substantial energy in aquatic food webs and are used as indicators of environmental change. Syntheses of zooplankton community dynamics globally require datasets that span a wide range of environmental gradients; however, these datasets are limited d...

Diversity and Classification of the Actinopeptins: A New Family of Lanthipeptides Within the Genomes from the Phylum Actinomycetota

Background/Objectives: Lanthipeptides are post-translationally modified compounds and have broad industrial potential. Six distinct classes of lanthipeptides are defined by the biosynthetic enzymes that install lanthionine and β-methyl-lanthionine. Notably, class II lanthipeptide...

Contrasting eruptive dynamics and hazards of two Holocene andesitic sub-Plinian to Plinian eruptions, Lower and Upper Citlaltépetl, at Pico de Orizaba, Mexico

Abstract Pico de Orizaba (Citlaltépetl) stratovolcano, eastern Mexico, preserves a complex Holocene explosive record, yet the eruptive dynamics, source parameters, styles, and hazard implications of individual eruptive episodes remain poorly constrained. Here, we examine the 9600...

Wh -questions and predication in Mayan

Abstract This paper examines the syntax of quantificational expressions in Chuj, a Mayan language spoken primarily in Guatemala and Mexico. Building on Royer, Buenrostro &amp; Jenks (2026), we argue that Chuj quantifiers fall into two distinct syntactic categories. Some quantifie...

Riding the Storm: Microeukaryote Community Responses to Hurricane Disturbance

Sandy beaches are dynamic ecosystems where terrestrial and marine organisms coexist, resulting in diverse communities where microeukaryotes (protists, microalgae, and meiofauna) are key drivers. Understanding their diversity patterns and responses to stressors is essential for el...

A comprehensive assessment of tandem repeat genotyping methods for Nanopore long-read genomes

Tandem repeats play critical roles in human disease and phenotypic diversity but are among the most challenging classes of genomic variation to measure accurately. Long-read sequencing has the potential to accurately characterize long and complex tandem repeats. While an increasi...

Partial Reproducibility and Pleiotropic Epigenetic QTLs in Arabidopsis Recombinant Inbred Lines

Unlike conventional genetic polymorphisms, many induced epigenetic polymorphisms can be reset across generations, raising uncertainty about how consistently the same epigenetic loci and associated phenotypic effects can be recovered among independent studies. To address this prob...
