Humans are parasitized by three types of lice: body, head and pubic lice. As their common names imply, each type colonizes a specific region of the body. The body louse is the only recognized disease vector. H...

At a time when we can feel sympathy even for Boris Johnson, my collection of toxin-resistant nits should give us hope“Am I right in remembering you cultivate a colony of head lice in your cellar, Lee?” Nicola Bridgens, former artist in residence at London Zoo, for whom I once provided the voice of a depressed black widow in an insect house installation, called me, coveting myPediculihumanuscapitis.Ten years ago, my little boy had nits. But if Paley ’s divine watchmaker exists, my precocious son argued, then he engineered lice to live in human hair. They were merely following their natures, so we should no...

The interleukin (IL)-1 family play a fundamental role as immune system modulators. Our previous transcriptome-analyses of leukocytes from lumpfish (Cyclopterus lumpus L.) showed that IL-1β was among the most highly upregulated genes following bacterial exposure. In the present study, we characterized IL-1 signaling pathways, identified and characterized four ligands of the IL-1 family in lumpfish; IL-1β type I and type II, IL-18, and the novel IL-1 family members (nIL-1F), both at mRNA and gene levels. The two IL-1β in lumpfish is termed IL-1β1 (type II) and IL-1β2 (type I). Furthermore, a comprehe...

r R Abstract The  cerium(IV) pyrazolate complexes [Ce(Me 2 pz) 4 ] 2  and [Ce(Me 2 pz) 4 (thf)] initiate  b -hydride abstraction of the bis(dimethylsilyl)amido moiety, to afford heteroleptic cerium(IV) species containing a dimethylpyrazolyl-substituted silylamido ligand, namely [Ce(Me 2 pz) 3 (bpsa)] (bpsa = bis((3,5-dimethylpyrazol-1-yl)dimethylsilyl)amido)), along with other cerium(III) species. Remarkably, the nucleophilic attack of the pyrazolyl at the silicon atom and concomitant Si-H-bond cleavage is restricted to the tetravalent cerium oxidation state and appears to proceed via the formation ...

by Kevin C. Cassidy, Jan Šefčík, Yogindra Raghav, Alexander Chang, Jacob D. Durrant Protein structure determines biological function. Accurately conceptualizing 3D protein/ligand structures is thus vital to scientific research and education. Virtual reality (VR) enables protein visualization in stereoscopic 3D, but many VR molecular-visualization programs are expensive and challe nging to use; work only on specific VR headsets; rely on complicated model-preparation software; and/or require the user to install separate programs or plugins. Here we introduce ProteinVR, a web-based application that works on va...

AbstractOrganizations use targeted recruitment to attract applicants with specific demographic characteristics to diversify the workforce. Research reports mixed findings regarding the extent to which beneficiaries (i.e., those specifically targeted) are attracted to organizations. We explore this inconsistency by investigating how U.S. college men and women (in Studies 1a,n = 239, and 1b,n = 223) and working adults (in Study 2,n = 128) respond to recruitment materials targeted toward members of the traditionally underrepresented gender—a police department that recruits women...

This study aims to investigate if and how habitat fragmentation affects the composition of ectoparasite communities on small mammalian hosts in two networks of dry deciduous forest fragments in northwestern Madagascar. Forest sites differing in size, proportion of edge habitat and host density were studied in the Ankarafantsika National Park and in the Mariarano region. A total of 924 individuals of two mouse lemur species, Microcebus murinus (n=200) and Microcebus ravelobensis (n=426), and two rodent species, endemic Eliurus myoxinus (n=114) and introduced Rattus rattus (n=184), were captured to assess ectoparasite infest...

Before COVID-19 swept across western Europe and caused schools and bars to close across the United States, it threatened East and Southeast Asia. Millions of Americans and Europeans are now learning to cope with changes to their daily lives brought on by coronavirus precautions—changes that have been a reality since January or February across mainland China and in places like Hong Kong, Singapore and Taiwan. For weeks, in many places across Asia, children have been home from school, employees have been working from home and people have been learning to conduct their lives amid the outbreak. With that in mind, here ...

Abstract The commercial farming of Atlantic salmon, Salmo salar, may require the periodic application of emamectin benzoate (EB) treatments to reduce the effects of biological pests, such as sea lice. As a result, EB is detected in sediments beneath these fish farms at considerable levels. Literature sediment toxicity data for EB for marine benthic species is only available for 10-day sediment toxicity tests, which might be too short to assess field effects. Here, we present a sediment toxicity test to determine 28-day mortality and growth effect concentrations for the non-target polychaete worm Arenicola marina, ...
