Comparing Synchronous and Asynchronous Remotely Delivered Lifestyle Interventions: Protocol for a Randomized Noninferiority Trial.

Background: Remotely delivered lifestyle interventions have emerged to increase the reach and accessibility of traditional interventions that involve numerous in-person visits. Remote interventions can be delivered synchronously via videoconference software or phone or asynchronously via online platforms. Asynchronously delivered interventions are convenient and flexible in that they allow people to participate at any time and as such, they may be more sustainable.

Deciphering circulating tumor cells binding in a microfluidic system thanks to a parameterized mathematical model.

The spread of metastases is a crucial process in which some questions remain unanswered. In this work, we focus on tumor cells circulating in the bloodstream, the so-called Circulating Tumor Cells (CTCs). Our aim is to characterize their trajectories under the influence of hemodynamic and adhesion forces.

Watching lanthanide nanoparticles one at a time: characterization of their photoluminescence dynamics at the single nanoparticle level.

Lanthanide nanoparticles (LnNPs) feature sharp emission lines together with millisecond emission lifetimes which make them promising luminescent probes for biosensing and bioimaging. Although LnNPs are attracting much interest, their photoluminescence properties at the single nanoparticle level remain largely unexplored. Here, we employ fluorescence correlation spectroscopy (FCS) and photoluminescence burst analysis to investigate the photodynamics of Sm- and Eu-based LnNPs with single nanoparticle sensitivity and microsecond resolution.

Mobilization of porewater Pb and Zn in response to seasonal wetting and drying within contaminated floodplains.

The mobility and bioavailability of metal contaminants such as lead (Pb) and zinc (Zn) is impacted by their interactions with other sediment constituents such as iron (Fe), sulfur (S), and organic matter, which depend on sediment redox conditions. Understanding the role that water level fluctuations have on redox conditions and subsequent impacts on metal mobility is critical for predicting impacts of increased wetting and drying cycles resulting from climate-related changes or management actions. This study measured the sediment-porewater partitioning of Pb and Zn in the Coeur d'Alene River basin downstream of the Bunker Hill Superfund Site under both flooded and seasonally dry conditions.
