Comparative evaluation of noncanonical amino acids as site‐specific NMR probes for the complex of E. coli SSB with single‐stranded DNA without isotope labelling

The FEBS Journal, EarlyView.
Genetic encoding of noncanonical amino acids (ncAA) enables their site‐specific installation in proteins. This work compares the nuclear magnetic resonance (NMR) performance of different ncAAs in a large protein−DNA complex (~ 100 kDa) without isotope labelling. The ncAAs deliver readily detectable NMR signals in the complex between E.

The Ecological Factors Associated With the Survival, Establishment, and Movement of Aedes aegypti and Ae. albopictus: A Scoping Review

Journal of Applied Entomology, EarlyView.
ABSTRACT Aedes aegypti and Ae. albopictus are mosquito species of public health significance and collectively responsible for the transmission of several arboviruses. Ongoing climatic changes are anticipated to have impacts on their survival, establishment, and movement.

Zoonotic anxieties: The cultural politics of Nepal's quest for pandemic preparedness

Medical Anthropology Quarterly, EarlyView.
Abstract Based on fieldwork conducted in Nepal (2022–2024) and by paying attention to how local and transnational notions of epidemiological risk are deployed, this ethnography introduces the concept of “zoonotic anxieties” to make sense of the multi‐species relational ethos that contemporary global health regimes propose.

Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

Medical and Veterinary Entomology, EarlyView.
The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...

Unravelling the biochemical aspects of the interaction between ticks and Leishmania using a tick cell line

Medical and Veterinary Entomology, EarlyView.
Leishmania infantum propagated in IDE8 tick cell line in vitro. L. infantum reduces tick cell viability and induces reactive oxygen species production. Lipidic profile of IDE8 tick cell line is altered during Leishmania infection. Abstract Leishmaniasis comprises a group of vector‐borne neglected tropical diseases caused by species of the obligatory ...

Mosquito and arbovirus surveillance in wetlands of South‐East England: Comparison of two adult mosquito traps, use of a novel trap with FTA™ cards and arbovirus testing

Medical and Veterinary Entomology, EarlyView.
Trap performance: Mosquito Magnet® captured significantly more mosquitoes overall, while BG‐Sentinel showed greater species evenness and was more effective for Culex pipiens s.l. and broader species representation. Spatial variation: Mosquito abundance and species composition varied significantly between wetlands, highlighting the importance of site ...
