Human Engineered Heart Tissues Reproduce Trigger‐ and Substrate‐Driven Mechanisms of Ventricular Tachycardia

open access: yesAdvanced Science, EarlyView.
Engineered heart tissues (EHTs) derived from human iPSCs replicate mechanisms of ventricular tachycardia at the tissue level. Acquired Long‐QT conditions cause early afterdepolarizations, wavebreak, and transient rotors; in contrast, focal cryoinjury forms a stable substrate that supports ongoing reentry.

Identification of planorbids from Venezuela by polymerase chain reaction amplification and restriction fragment length polymorphism of internal transcriber spacer of the RNA ribosomal gene

open access: yesMemorias do Instituto Oswaldo Cruz, 2000
Snails of the genus Biomphalaria from Venezuela were subjected to morphological assessment as well as polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) analysis.

Molecular identification of similar species of the genus Biomphalaria (Mollusca: Planorbidae) determined by a polymerase chain reaction-restriction fragment length polymorphism

open access: yesMemorias do Instituto Oswaldo Cruz, 1998
The freshwater snails Biomphalaria straminea, B. intermedia, B. kuhniana and B. peregrina, are morphologically similar; based on this similarity the first three species were therefore grouped in the complex B. straminea.

Hydrodynamic Selection of Polymorphic Assembly Pathways in Plant Protein Amyloid Fibrils

open access: yesAdvanced Science, EarlyView.
Hydrodynamic conditions are revealed to govern polymorphic assembly of soy protein amyloid fibrils. Distinct flow‐induced drafting, kissing, and docking dynamics direct fibril growth into multiple morphologies, linking fluid mechanics with nanoscale assembly and enabling rational design of functional amyloid materials.

An Integrated Framework Coupling Hierarchical Hyperspectral i‐trait Screening, Gene Identification, and Functional Validation for Genetic Dissection of Salt Tolerance in Cotton

open access: yesAdvanced Science, EarlyView.
An integrated phenomics–genomics framework captures dynamic salt‐stress responses in laboratory‐grown cotton seedlings through time‐series hyperspectral imaging and non‐destructive i‐trait extraction. Hierarchical screening identifies biologically relevant, heritable, and non‐redundant traits for high‐resolution GWAS, identifying GhST7.

Amyloid‐Guided Assembly of Magnetically Recyclable Enzymatic Nanofibers Toward Sustainable Biocatalysis

open access: yesAdvanced Science, EarlyView.
A hierarchical strategy integrates linker engineering, amyloid‐guided self‐assembly, and magnetic immobilization to construct recyclable DPAO4‐DMAO7 enzymatic nanofibers. The resulting magnetic composites enable biogenic amine conversion in complex food matrices and simulated wastewater, while rapid magnetic separation supports repeated reuse. The work

ALDH2 Deficiency Promotes Mitochondrial Oxidative Stress and Adverse Limb Outcomes via VDAC–HSP60 Signaling

open access: yesAdvanced Science, EarlyView.
ALDH2 deficiency promotes 4‐HNE accumulation, resulting in covalent modification of HSP60, disruption of its oligomeric assembly, and VDAC1‐dependent release of HSP60 from mitochondria to the cytosol. Pharmacological activation of ALDH2 preserves HSP60 proteostasis and mitochondrial integrity, whereas the clinical association between the ALDH2 rs671 ...

MOLECULAR CHARACTERIZATION OF ‘Candidatus PHYTOPLASMA MALI’ STRAINS FROM BULGARIA AND POLAND

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2019
During 2015, samples from 22 apple trees showing proliferation symptoms were collected in southwest Bulgaria and Central and South Poland and tested for phytoplasma presence. ‘Candidatus Phytoplasma mali’ was identified in 18 samples based on results of

Fine‐scale genetic structure of the cloud forest tree Ocotea psychotrioides revealed by genome‐wide SNP data

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Recent advances in genomic technologies now enable the reconstruction of evolutionary histories at fine spatial scales, illuminating the complex dynamics that shape biodiversity patterns in naturally discontinuous, archipelago‐like ecosystems such as cloud forests.
