Phylogenetic Insights on Patterns of HIV-1 Spread and the Design of Epidemic Control Measures

open access: yesViruses, 2022
Phylogenetics provides a unique structural framework to track the spread of viral diseases, such as HIV-1 (human immunodeficiency virus type 1), the causative agent of AIDS (acquired immunodeficiency syndrome) [...]

Relapsing–Remitting Multiple Sclerosis Is Associated With a Dysbiotic Oral Microbiome

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Multiple sclerosis (MS) is a chronic autoimmune disorder characterized by inflammation, demyelination, and neurological impairment. While the gut microbiota's role in MS is extensively studied, the association between the oral microbiota and MS remains underexplored, particularly in North American cohorts.

DNA barcodes reveal population-dependent cryptic diversity and various cases of sympatry of Korean leptonetid spiders (Araneae: Leptonetidae)

open access: yesScientific Reports, 2022
Leptonetidae are tiny, rarely encountered spiders that mainly inhabit moist environments, such as caves, leaf litter, and rock piles. Because they are microhabitat specialists, most leptonetid species have short-range endemism, and rarely occur in ...

pH‐Tunable Material Properties of Glycine‐Rich Condensates from Tick Bioadhesive

open access: yesAdvanced Functional Materials, EarlyView.
This work studies the influence of pH on the phase separation behavior of a disordered glycine‐rich protein found in tick bioadhesive. The results show profound impact on the propensity of coacervation, condensate microstructure and viscosity, amphiphilicity of the peptides, and effective encapsulation of therapeutic molecules.

Micro and Nanostructural Diversity of Lizard Osteoderm Capping Tissue in Relation to Mechanical Performance

open access: yesAdvanced Functional Materials, EarlyView.
This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.

Is it time to abandon the flow cytometry in estimations of genome size when the K-mer analysis is available? The case of Engelhardia species

open access: yesGenomics Communications
Genome size represents a fundamental genomic trait with profound implications across evolutionary biology, ecology, and genomics. Flow cytometry (FCM) has served as the gold standard for estimating genome size for decades, while the advent of next ...

Quartets enable statistically consistent estimation of cell lineage trees under an unbiased error and missingness model

open access: yesAlgorithms for Molecular Biology, 2023
Cancer progression and treatment can be informed by reconstructing its evolutionary history from tumor cells. Although many methods exist to estimate evolutionary trees (called phylogenies) from molecular sequences, traditional approaches assume the ...

Modeling the Ecology and Evolution of Biodiversity: Introduction to the Special Issue

open access: yesDiversity, 2022
Applying relevant statistical models to empirical data analysis has been considered a very important procedure for scientists to answer research questions in the fields of biodiversity, phylogeography, evolutionary biology, paleoecology, phylogenetics ...

Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

open access: yesAdvanced Healthcare Materials, EarlyView.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

Survey of molecular phylogenetics

open access: yesPlant, Soil and Environment, 2007
Rapidly increasing amount of biological data necessarily requires techniques that would enable to extract the information hidden in the data. Methods of molecular phylogenetics are commonly used tools as well as objects of continuous research within many
