Speciation and hybridization in invasive fire ants

open access: yesBMC Evolutionary Biology, 2019
Background A major focus of evolutionary biology is the formation of reproductive barriers leading to divergence and ultimately, speciation. Often, it is not clear whether the separation of populations is complete or if there still is ongoing gene flow ...

Reaction-diffusion in a growing 3D domain of skin scales generates a discrete cellular automaton

open access: yesNature Communications, 2021
The adult ocellated lizard skin colour pattern is effectively generated by a stochastic cellular automaton (CA) of skin scales. Here authors use reaction diffusion (RD) numerical simulations in 3D on realistic lizard skin geometries and demonstrate that ...

Microscopic Malaria Infection and Its Determinants in Urban and Rural Populations Living in South-East Gabon

open access: yesJournal of Parasitology Research
A better understanding of malaria epidemiology in both asymptomatic and symptomatic individuals is essential for developing strategies to control the disease.

DNA Polymerases Engineered by Directed Evolution to Incorporate Nonstandard Nucleotides

open access: yesFrontiers in Microbiology, 2014
DNA polymerases have evolved for billions of years to accept natural nucleoside triphosphate substrates with high fidelity and to exclude closely related structures, such as the analogous ribonucleoside triphosphates. However, polymerases that can accept

Genomic architecture of adaptive radiation and hybridization in Alpine whitefish

open access: yesNature Communications, 2022
In this genomic study on Alpine whitefish radiations, the authors reveal details on the genetic architecture underlying the repeated eco-morphological diversification and the role of hybridization in the evolution of endemic whitefish species.

DELP Treatment on Vision and Retinal Microcirculation in Patients With Acute Ischemic Stroke: Report of Five Cases and Literature Review

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.

Deconstructing the geography of human impacts on species’ natural distribution

open access: yesNature Communications
It remains unknown how species’ populations across their geographic range are constrained by multiple coincident natural and anthropogenic environmental gradients.

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

open access: yesFEBS Letters, EarlyView.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...

Evolutionary and Expression Analyses Show Co-option of khdrbs Genes for Origin of Vertebrate Brain

open access: yesFrontiers in Genetics, 2018
Genes generated by whole genome duplications (WGD) can be co-opted by changing their regulation process or altering their coding proteins, which has been shown contributable to the emergence of vertebrate morphological novelties such as vertebrate ...

Systematic errors in orthology inference and their effects on evolutionary analyses

open access: yesiScience, 2021
Summary: The availability of complete sets of genes from many organisms makes it possible to identify genes unique to (or lost from) certain clades. This information is used to reconstruct phylogenetic trees; identify genes involved in the evolution of ...
