Speciation and historical invasions of the Asian black-spined toad (Duttaphrynus melanostictus).

Animal translocations provide striking examples of the human footprint on biodiversity. Combining continental-wide genomic and DNA-barcoding analyses, we reconstructed the historical biogeography of the Asian black-spined toad (Duttaphrynus melanostictus), a toxic commensal amphibian that currently threatens two biodiversity hotspots through biological invasions (Wallacea and Madagascar). The results emphasize a complex diversification shaped by speciation and mitochondrial introgression that comprises two distinct species.

Taxonomy of Iranian Asaccus (Squamata: Phyllodactylidae) with description of a new species from southern Iran.

We provide the first diversity assessment of Iranian species of the genus Asaccus based on COI DNA-barcoding. We analyzed 53 samples of Iranian Asaccus representing nine OTU corresponding to 10 currently recognzied nominal species, and evaluated both morphological and genetic data to support the recognition of a new species from Bandar-e Jask, Hormozgan Province, southern Iran-Asaccus authenticus sp. nov.

Ionic current blockade in a nanopore due to an ellipsoidal particle.

Nanopores in solid-state membranes have been used to detect, identify, filter, and characterize nanoparticles and biological molecules. In this work, we simulate an ionic flow through a nanopore while an ellipsoidal nanoparticle translocates through a pore. We numerically solve the Poisson-Nernst-Planck equations to obtain the ionic current values for different aspect ratios, sizes, and orientations of a translocating particle.

Taxonomic diversity of racerunners with descriptions of two new Eremias species (Sauria: Lacertidae) from Central Iran.

We provide a diversity assessment of Iranian species of the genus Eremias based on the cytochrome oxidase I mtDNA gene fragment. We analyzed 93 genetic samples from the entire distribution of the Eremias fasciata species complex in Iran and surrounding regions, along with morphological data to support the description of two new species from Central Iran. We hypothesize that the diversification of the Eremias fasciata species complex was largely influenced by the fragmentation of sand massifs in the region.

Osteoderm Development during the Regeneration Process in Blyth, 1854 (Scincidae, Sauria, Squamata).

Osteoderms are bony structures that develop within the dermal layer of the skin in vertebrates and are very often found in different lizard families. Lizard osteoderms are diverse in topography, morphology, and microstructure. Of particular interest are the compound osteoderms of skinks, which are a complex of several bone elements known as osteodermites.

The colonial legacy of herbaria.

Herbarium collections shape our understanding of Earth's flora and are crucial for addressing global change issues. Their formation, however, is not free from sociopolitical issues of immediate relevance. Despite increasing efforts addressing issues of representation and colonialism in natural history collections, herbaria have received comparatively less attention.

Varicella Manifestation after Mastopexy with Simultaneous Breast Augmentation.

We report on a rare case of primary varicella infection manifestation in the early postoperative period after mastopexy with simultaneous breast augmentation that caused dehiscence of surgical wound edges and spread of infection to a subcutaneous fat layer, leading to unaesthetic scarring. Whether such dehiscence in the background of varicella occurred coincidentally or was specifically triggered by the infection is unknown. The treatment is comprised of oral antiviral therapy, surgical wound debridement, and topical application of antiseptic solutions and ointments.

The subjectively perceived injectability as an early indicator for adverse events?

Background: With an increasing demand of aesthetic soft-tissue filler treatments, the occurrence of adverse events rises likewise. An optimized injection algorithm adapted to product characteristics (eg, rheology) of the soft-tissue filler is crucial in order to ensure satisfying clinical outcomes and high patient safety.

Objective: To identify a subjective feedback mechanism for the avoidance of adverse events after soft-tissue filler injection procedures.

Brownian dynamics of cylindrical capsule-like particles in a nanopore in an electrically biased solid-state membrane.

We use Brownian dynamics simulations to study the motion of cylindrical capsule-like particles (capsules) as they translocate through nanopores of various radii in an electrically biased silicon membrane. We find that for all pore sizes the electrostatic interaction between the particle and the pore results in the particle localization towards the pore 's center when the membrane and the particle have charges of the same sign (case 1) while in case of the opposite sign charges, the capsule prefers to stay near and along the nanopore wall (case 2). The preferential localization leads to all capsules rotating less while inside the pore compared to the bulk solution, with a larger net charge and/or particle length resulting in a smaller range of rotational movement.

Multiscale simulations of charge and size separation of nanoparticles with a solid-state nanoporous membrane.

Nanoporous membranes provide an attractive approach for rapid filtering of nanoparticles at high-throughput volume, a goal useful to many fields of science and technology. Creating a device to readily separate different particles would require an extensive knowledge of particle-nanopore interactions and particle translocation dynamics. To this end, we use a multiscale model for the separation of nanoparticles by combining microscopic Brownian dynamics simulations to simulate the motion of spherical nanoparticles of various sizes and charges in a system with nanopores in an electrically biased membrane with a macroscopic filtration model accounting for bulk diffusion of nanoparticles and membrane surface pore density.
