Temperate and tropical lineages of brown dog ticks in North America

Veterinary Parasitology: Regional Studies and Reports, 2017
Recent studies document that brown dog ticks, previously considered as Rhipicephalus sanguineus, are actually comprised of multiple taxonomic units now referred to as Rhipicephalus sanguineus sensu lato (Rssl); two lineages of Rssl have been described in the Americas to date - tropical and temperate.

tBid‐Mediated Genetic Ablation of Connective Tissue Cells Reveals Their Key Regulatory Function During Limb Regeneration in Axolotls

Advanced Science, EarlyView.
We establish a tBid‐mediated cell ablation system in axolotls, achieve rapid and efficient ablation of multiple cell types, including muscle stem cell, spinal cord cell, and connective tissue (CT) cells. We investigate the role of CT using tBid‐mediated CT ablation and identify its essential role for limb development and regeneration.

Targeting DNGR‐1 with Fangchinoline Elevates Dendritic Cell Antigen Cross‐Presentation‐Mediated Antitumor Immunity in Melanoma

Advanced Science, EarlyView.
Fangchinoline is identified as a small‐molecule DNGR‐1 modulator that enhances dendritic‐cell cross‐presentation of tumor antigens. By engaging DNGR‐1 and activating Syk–Nox2 signaling, it promotes phagosomal ROS, antigen escape, MHC‐I presentation, and CD8+ T‐cell priming, thereby strengthening antitumor immunity and sensitizing tumors to PD‐1 ...

Year-round efficacy of a single treatment of fluralaner injectable suspension (Bravecto Quantum™) against repeated infestations with Rhipicephalus sanguineus (sensu lato) and Ctenocephalides felis in dogs

Parasites & Vectors, 2023
Background Poor owner compliance with monthly control measures means that dogs in Australia can remain susceptible to infestations with fleas, present throughout the whole year, and brown dog ticks, which thrive in tropical and subtropical areas.

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

The Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

SUSCEPTIBILITY OF RHIPICEPHALUS SANGUINEUS SENSULATO (S.L.) LATREILLE (ACARI: IXODIDAE) TO CYPERMETHRIN, IVERMECTIN, AND AMITRAZ [PDF]

Exploratory Animal and Medical Research
Chemical acaricides, viz. amitraz, cypermethrin, and ivermectin have been in use for control of ectoparasites (particularly ticks) in domestic animals over the past two decades.

Reception Baseline Assessment and ‘small acts’ of micro‐resistance

British Educational Research Journal, EarlyView.
Abstract In September 2021, following the global COVID‐19 pandemic, the Department for Education introduced a national standardised digital Reception Baseline Assessment (RBA) for all English 4‐year‐old children. We analyse RBA and its associated Quality Monitoring Visits, as a further intensification of the new public management of early years ...
