Ancient Yersinia pestis genomes from across Western Europe reveal early diversification during the First Pandemic (541–750)

, 2019
The first historically documented pandemic caused by Yersinia pestis began as the Justinianic Plague in 541 within the Roman Empire and continued as the so-called First Pandemic until 750.

Ancient DNA from mastics solidifies connection between material culture and genetics of mesolithic hunter–gatherers in Scandinavia

Communications Biology, 2019
Human demography research in grounded on the information derived from ancient DNA and archaeology. For example, the study on the early postglacial dual-route colonisation of the Scandinavian Peninsula is largely based on associating genomic data with the

Assessment of Gold‐Mediated Male Reproductive Dysfunction in Male WISTAR Rats Through Sperm Analysis and Testosterone Measurement

Journal of Applied Toxicology, EarlyView.
ABSTRACT Gold has been used for centuries in both ornamental and medicinal contexts. More recently, gold compounds, containing ions or nanoparticles, have attracted attention for their anti‐inflammatory, anticancer, and diagnostic applications. Therefore, concerns about systemic toxicity and biodistribution have prompted investigations into the ...

Hurdles in investigating UVB damage in the putative ancient asexual Darwinula stevensoni (Ostracoda, Crustacea) [PDF]

, 2013
Ostracoda or mussel-shrimps are small, bivalved Crustacea. Because of their excellent fossil record and their broad variety of reproductive modes, ostracods are of great interest as a model group in ecological and evolutionary research.

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius
