Impact of undernutrition on apoptotic pathways and thymocyte development in rats: insights into caspase activation and mitochondrial dysfunction

Abstract Undernutrition significantly compromises immune function, particularly in vulnerable populations. This study explored the effects of undernutrition on apoptotic pathways and thymocyte development in rats, shedding light on potential mechanisms underlying immunosuppressio...

Advanced oxidation processes for 2,4-dichlorophenoxyacetic acid in aqueous media: evidence gaps, mechanistic insights and emerging directions

Abstract The herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) remains a relevant aquatic contaminant because parent-compound disappearance does not imply mineralization, detoxification or treatment readiness. This systematic review synthesizes recent evidence on advanced oxidatio...

Influence of functional traits and trait syndromes on the vulnerability of amphibians and reptiles in the tropical dry forest of Oaxaca, Mexico

Abstract Tropical dry forests are among the most threatened ecosystems worldwide, yet their biodiversity remains understudied compared to humid tropical forests. We integrated functional trait ecology with environmental vulnerability assessments to evaluate multi‑causal disturban...

Empagliflozin and Metformin Combination Therapy Attenuates Oxidative Stress and Inflammation in Experimental Cardio–Kidney–Metabolic Syndrome

This study evaluated the therapeutic effects of the empagliflozin+metformin (E+M) combination on cardio–kidney–metabolic syndrome (CKMS) using an experimental model. Animals were fed a Paigen-type (high-fat) diet supplemented with sugar-sweetened beverages to induce the CKMS phen...

Whey Protein–Polysaccharide Nanocomplexes: Structure–Function Characterization and Bone-Related Outcomes in Ovariectomized Rats

Background/Objectives: Estrogen deficiency is associated with impaired bone mineralization and deterioration of bone quality. Protein–polysaccharide nanostructures have attracted interest as food-grade formulations because their physicochemical properties can be modified by the n...

Stomatal complexes in Mimosa L. (Caesalpiniodeae, Leguminosae), a literature review

The study of stomatal complexes has provided characters that allow for species recognition, so this area of research is critical, mainly in families with a high concentration of genera that are problematic about the recognition and classification of their taxa. Mimosa L. belongs...

2,4-Dichlorophenol Photodegradation by Novel Burtite-like Solid Solutions: Effect of Sn4 + and Al3 + Content on the Physicochemical Properties and Photocatalytic Performance

Abstract Nowadays, tailoring the physicochemical properties of novel photocatalysts is crucial for advanced environmental remediation technologies. Thus, in this work, novel solid solutions of burtite-like compounds with nominal Sn amounts of 5.3–27.8 mol % were synthesized. Mate...

Polarization dynamics of an NPR-based Q-switched mode-locked twisted fiber ring laser

In this work, we study the passive mode-locked and Q-switched mode-locked (QSML) operations of an erbium-doped fiber ring laser with twisted fiber in the cavity. Using twisted fiber together with precisely adjusted wave retarders, this configuration allows very tight polarization...

Weather Extreme Events, Farm Management, and Cocoa Yield in Ecuador

The frequency and intensity of extreme weather events are increasing, yet their implications for perennial tree crops such as cocoa remain understudied. Existing cocoa-climate evidence is based on mean climate variables, discrete shocks, and concentrated in West and Central Afric...

Computational Methods in Physical Virology: A Critical Perspective across lengths and timescales

Physical virology investigates viral particles by focusing on their assembly, stability, mechanics, and interactions with host cells, neutralizing antibodies, and surfaces. Within this field, computational virology is becoming an indispensable pillar, serving as a "computational...

Ecological risk of the pesticide imiprothrin and microplastics separately and combined on demography of cladocerans (Cladocera)

We tested different concentrations of the synthetic pyrethroid (imiprothrin) (IP) and microplastics (MPs) (alone and combined) on the demography and population growth of two cladoceran species (Ceriodaphnia dubia and Simocephalus vetulus). The two test concentrations of IP for C....

Integrative Multi‐Omics Analysis Identifies Candidate MicroRNA Regulatory Networks Associated With High‐Altitude Adaptation in Tibetan Pigs

MicroRNAs (miRNAs) are key posttranscriptional regulators of gene expression and play important roles in physiological responses to hypoxia, particularly in the cardiovascular system. However, the regulatory roles of miRNAs in cardiopulmonary tissues during high-altitude adaptati...

Long-term diatom response to anthropogenic stressors in a Neotropical lake

Understanding tropical lake ecosystem responses to anthropogenic disturbance over long timescales is critical for assessing resistance, resilience, and regime shifts; however, such perspectives are rare in the Neotropics. We combined paleolimnological, limnological, and remote-se...

Ser715 Phosphorylation Induces β-Hairpin Unfolding and Destabilization of FOXM1 Autoinhibition.

FOXM1 is a cell proliferation-driving transcription factor activated by phosphorylation-induced conformational changes. In its inactive state, an intramolecular β-hairpin within the transactivation domain (TAD) binds the N-terminal repressor domain (NRD), forming a composite β-sh...

Synthesis and characterization of polymer networks obtained by conventional radical and RAFT copolymerization processes in supercritical carbon dioxide

Abstract The syntheses of net ‐poly((2‐hydroxyethylene methacrylate)‐ co ‐(ethylene glycol dimethacrylate)), abbreviated as net ‐poly(HEMA‐ co ‐EGDMA), by conventional (FRP) and reversible addition‐ fragmentation chain transfer (RAFT) radical copolymerizations using supercritical...

Bismuth Nanogratings With Narrow Plasmon Resonances for Dynamic Polarized Color Generation and Colorimetric Sensing

ABSTRACT Bismuth nanostructures are appealing for sustainable color generation and sunlight harvesting, thanks to their non‐toxicity and their tunable visible‐to‐near‐infrared interband plasmon resonances. However, owing to their broad and polarization‐insensitive spectral featur...

Complex Thinking as a Predictor of Anxiety Symptoms in Medical Students

Abstract Introduction Medical training is associated with a high prevalence of anxiety symptoms that escalate with curricular advancement. Complex thinking has been proposed as a protective cognitive skill; however, its predictive capacity and evolution throughout training remain...

Agave Species Influence the Taxonomic and Predicted Functional Structure of Traditional Pulque Inoculum Microbiomes

Pulque is a traditional Mexican beverage produced by the spontaneous fermentation of “aguamiel”, the sap of several Agave species. Fermentation is driven by adding a previously fermented inoculum, locally known as “semilla”, whose microbial community contributes to the sensory an...

FAK regulates leptin-induced angiogenesis and vasculogenic mimicry in breast cancer

Abstract Leptin, an adipokine primarily secreted by adipose tissue, has been implicated in tumor progression by regulating angiogenesis. Leptin also plays a key role in tumor vascularization by promoting vasculogenic mimicry (VM). During tumor progression, leptin activates severa...

Standardized Sechium edule root extract attenuates LPS inflammation alongside transient STAT3 phosphorylation and an interleukin 10 biased macrophage response

Chronic low-grade inflammation is sustained by macrophage activation toward proinflammatory states and contributes to cardiometabolic and degenerative disorders. Given the growing interest in evidence-based medicinal plants, we investigated whether a hydroalcoholic root extract o...
