Environ Sci Technol

January 2025

Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, Virginia 24061, United States.

The stability of influenza virus in respiratory particles varies with relative humidity (RH) and protein content. This study investigated the decay, or loss of infectivity, of influenza A virus (IAV) in 1-μL respiratory droplets deposited on a surface with varying concentrations of mucin, one of the most abundant proteins in respiratory mucus, and examined the localization of virions within droplets. IAV remained stable at 0.

Purpose: Most auditory-perceptual voice research utilizes the judgments of trained listeners rather than everyday listeners with no previous training in speech pathology. Online crowdsourcing of behavioral data from untrained participants is rapidly increasing in popularity but has yet to be a common procedure for auditory-perceptual studies of the voice. The objective of this pilot study was to assess the functionality of this model for judgments of voice by using an online experiment platform to replicate a lab-based, voice-specific age estimation study.

Metal oxides are promising catalysts for small molecule hydrogen chemistries, mediated by interfacial proton-coupled electron transfer (PCET) processes. Engineering the mechanism of PCET has been shown to control the selectivity of reduced products, providing an additional route for improving reductive catalysis with metal oxides. In this work, we present kinetic resolution of the rate determining proton-transfer step of PCET to a titanium-doped POV, TiVO(OCH) with 9,10-dihydrophenazine by monitoring the loss of the cationic radical intermediate using stopped-flow analysis.

Protocol for the Generation and 3D Culture of Fluorescently Labeled Multicellular Spheroids.

Methods Mol Biol

January 2025

Department of Internal Medicine II, University Hospital Frankfurt, Goethe University Frankfurt, Frankfurt am Main, Germany.

Spheroid culture systems have been extensively used to model the three-dimensional (3D) behavior of cells in vitro. Traditionally, spheroids consist of a single cell type, limiting their ability to fully recapitulate the complex inter-cellular interactions observed in vivo. Here we describe a protocol for generating cocultured spheroids composed of two distinct cell types, embedded within a 3D extracellular matrix (ECM) to better study cellular interactions.

Department of Physical Therapy & Rehabilitation Science, Carver College of Medicine, the University of Iowa, Iowa City, IA, 52242, USA.

Nociceptors contribute to the cardiovascular responses during a cold pressor test (CPT). While these responses are lower in females, data suggest that they perceive the CPT as more painful. Thus, we examined sex differences in associations between pain and cardiovascular responses to a CPT (Aim 1) as well as differences between females using (OC), and not using (NC), an oral contraceptive (Aim 2).
