eDIY-sampler: an effective low-cost, compact and reproducible filtration system for aquatic eDNA sampling

Knowledge and Management of Aquatic Ecosystems
Environmental DNA (eDNA) methods are now commonly used for aquatic biodiversity monitoring, yet a lack of protocol standardization and the high cost of commercial samplers hinder broader application and results comparisons.

Self-reported pregnancy exposures and placental DNA methylation in the MARBLES prospective autism sibling study. [PDF]

, 2016
Human placenta is a fetal-derived tissue that offers a unique sample of epigenetic and environmental exposures present in utero. In the MARBLES prospective pregnancy study of high-risk younger siblings of children with autism spectrum disorder (ASD ...

Mitogenomic Insights into Orthocladiinae (Diptera: Chironomidae): Structural Diversity and Phylogenetic Implications

Biology
Mitochondrial genomes are powerful tools for taxonomic delimitation and species identification, yet they remain scarce for Chironomidae (Diptera). In this study, we assembled and annotated 63 new mitochondrial genomes, encompassing 63 species within 39 ...

Blinking statistics of a molecular beacon triggered by end-denaturation of DNA

, 2005
We use a master equation approach based on the Poland-Scheraga free energy for DNA denaturation to investigate the (un)zipping dynamics of a denaturation wedge in a stretch of DNA, that is clamped at one end.

Preliminary survey of Aphanomyces sp. associated with native and invasive crayfish in the Lower Susquehanna watershed of South Central Pennsylvania

Journal of Freshwater Ecology, 2020
The oomycete species, Aphanomyces astaci, is well known as the devastating causal agent of European crayfish plague. Despite assumptions of a North American origin, the prevalence and distribution of A. astaci in its presumed native range is unknown.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
