Respiratory Syncytial virus (RSV) is a major threat to many vulnerable populations. There are currently no approved vaccines, and RSV remains a high unmet global medical need. Here we describe the employment of a novel synthetic DNA-encoded antibody technology platform to develop and deliver an engineered human DNA-encoded monoclonal antibody (dMAbTM) targeting the fusion protein (F) of RSV as a new approach to prevention or therapy of at risk populations. In in vivo models, a single administration of synthetic DNA-encoding the single-chain fragment variable-constant fragment (scFv-Fc) RSV-F dMAb resulted in robust and durable circulating levels of a functional antibody systemically and in mucosal tissue. In cotton rats, which are the gold-standard animals to model RSV infection, we observed sustained scFv-Fc RSV-F dMAb in the sera and lung-lavage samples, demonstrating the potential for both long-lasting immunity to RSV and effective biodistribution. The scFv-Fc RSV-F dMAb harbored in the sera exhibited RSV antigen-specific binding and potent viral neutralizing activity. Importantly, in vivo delivery of synthetic DNA-encoding, the scFv-Fc RSV-F dMAb protected animals against viral challenge. Our findings support the significance of dMAbs as a potential platform technology for durable protection against RSV disease.This study examined core belief violation and meaning making as mechanisms mediating the relationship between adherence to social isolation policies for mitigating coronavirus transmission and reduced coronavirus anxiety (CA). Adherence to social isolation policies (social distancing, sheltering in place, and cessation of long-distance travel), use of nonsocial precautionary measures (handwashing, wearing a mask), core belief violation, meaning made of the COVID pandemic, and CA were assessed in a sample of 408 North Americans. Process analysis revealed that adhering to social isolation policies predicted lower levels of CA and that this effect was largely mediated by conservation of core beliefs (e.g., in predictability, control, and self-agency) and ability to make meaning of the pandemic. In contrast, exclusive reliance on nonsocial protections such as handwashing and mask wearing was associated with high levels of CA. These results suggest that social isolation policies support the integrity of adherents' meaning systems, thereby mitigating distress, which carries useful implications for both policy and psychological intervention.Objectives Although hearing has been shown to interact with sleep, the underlying mechanisms for the interaction remain largely unclear. In the absence of knowledge about the neural pathways that are associated with hearing-sleep interaction, this study aimed to examine whether the auditory radiation, the final portion of the auditory pathway from the cochlea to the cerebral cortex, shows association with sleep duration. Methods Using Diffusion Tensor Imaging (DTI) data from enhanced Nathan Kline Institute-Rockland Sample (NKI-RS), we isolated the white matter tracts between the medial geniculate nucleus of the thalamus and Heschl's gyrus in each individual subject (N = 465) using probabilistic tractography. selleck As a measure of the white matter microstructure integrity, the mean fractional anisotropy (FA) of the whole auditory radiation was examined and tested for an association with sleep length in the Pittsburgh Sleep Assessment Index. Results A significant inverse-U shaped association was found between the auditory radiation FA and sleep duration. Discussion It is suggested that the auditory radiations are a part of the pathway mediating the sleep-hearing interaction. Although the current study does not resolve the causal relationship between hearing and sleep, it would be the first evidence that the auditory radiation is associated with sleep duration.Objective Recent publications on Coronavirus Disease-2019 (COVID-19) report that diabetic people with or without co-morbiditi
