Blood feeding female mosquitoes cause itchy welts and can transmit pathogens that cause diseases such as chikungunya, malaria, West Nile encephalitis, and Zika. Mosquito control programs conduct mosquito, pathogen, and epidemiological surveillance, carry out source reduction, treat mosquito habitats with larvicides or adulticides, and disseminate information to the public. Here, 100 organizations (e.

Dendritic cells (DCs) have emerged as a promising target for drug delivery and immune modulation due to their pivotal role in initiating the adaptive immune response. Gold nanoparticles (AuNPs) have garnered interest as a platform for targeted drug delivery due to their biocompatibility, low toxicity and precise control over size, morphology and surface functionalization. Our investigation aimed to elucidate the intracellular uptake and trafficking of AuNPs coated with different combinations of monosaccharides (mannose, galactose, and fucose) in DCs.

Objectives: Ultrasonographic assessment of giant cell arteritis (GCA) relies on the demonstration of a non-compressible halo. Several ultrasonographic methods have been developed to quantify arterial wall thickness, however arterial compressibility has not been quantified. This study presents a possible solution for quantifying compressibility to assist in diagnosing GCA.

Background: The declaration of mpox as a Public Health Emergency of International Concern highlights the need for interventions to interrupt virus transmission, including transmission via fabrics. Current World Health Organization guidance on clothes washing is based on a general consensus of virus inactivation; however, there is uncertainty about the efficacy of laundry detergents and disinfectants or the reduction of risk achieved by washing clothes for monkeypox virus (MPXV) specifically.

Methods: This study investigates the efficacy of manual washing for inactivating MPXV from clothes.

The frog fauna of New Guinea is exceptionally diverse but very poorly known. Here we describe a new species of pelodryadid treefrog that is currently known only from two specimens from a single site in Hela Province in the highlands of Papua New Guinea. Genetic data show that the new species is closely related to the torrent-breeding species Litoria angiana (Boulenger, 1915) from which it can be readily distinguished by its more slender body and limbs, relatively long forelimbs, and aspects of body colouration and tuberculation.
