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...

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, ...

Abstract Infestations and arthropod bite reactions in children are common reasons for presentation to pediatric health care providers. Infestations in children include head lice, scabies, and other mites. Fleas and bed bugs are common causes of bite reactions in children, and papular urticaria is a chronic, recurrent eruption resulting from delayed hypersensitivity to a variety of insect bites. Both infestations and bite reactions may result in severe pruritus with associated sleep disturbance and can be a source of significant distress for patients and families. In this review, we discuss infestations and bite re...

We report a variety of ectoparasites infesting small mammals and domestic dogs in the Caatinga biome, where these ectoparasites probably act as vectors of rickettsiae, ehrlichial agents (E. canis and Ehrlichia sp. strain Natal) and C. burnetii. Our results highlight to the potential risks of human infection by these tick-borne agents in the Caatinga biome.

Abstract Most human epidemiological and clinical studies use visual inspection of the hair and scalp to diagnose Pediculus humanus capitis , however this method has low sensitivity to diagnose active infestations (presence of nymphs and adult lice). Vacuuming the hair and scalp has been used as a diagnostic method, but there are no previous data comparing its effectiveness with visual inspection. The aim of this study was to determine the prevalence of overall infestation (nits and trophic stages), of active infestation by Pediculus humanus capitis , and to evaluate the effectiveness of vacuuming in comparison wit...

We describe the infections that appeared in the life and work of John Donne (1572-1631), the English metaphysical poet, mainly the exanthematic typhus that suffered and gave arise to his work Devotions upon emergent occasions, and several steps in my sickness. We discuss the vector of transmission of this disease, in comparison of other infections in that period, that Donne´s scholars have related to the flea without mentioning the body louse, the true vector of the exanthematic typhus. Likewise, we mention the exanthematic typhus´s symptoms in his Devotions in comparison with the Luis de Toro´s or Alfons...
