Background: Chagas heart disease (ChD) is a significant public health concern in Latin America, contributing to a high incidence of sudden cardiac death (SCD). Despite advances in heart failure treatment, management of Chagas cardiomyopathy has not progressed accordingly. While ICDs are effective for primary and secondary prevention in other conditions, patients with ChD often experience more frequent episodes of ventricular tachycardia, and ICD use may provide a negative impact and increase mortality.

Proto-SLIPS: Slippery Liquid-Infused Surfaces that Release Highly Water-Soluble Agents.

ACS Appl Mater Interfaces

September 2025

Department of Chemistry, University of Wisconsin-Madison, 1101 University Ave., Madison, Wisconsin 53706, United States.

Slippery liquid-infused porous surfaces (or "SLIPS") can prevent bacterial surface fouling, but they do not inherently possess the means to kill bacteria or reduce cell loads in surrounding media. Past reports show that the infused liquids in these materials can be leveraged to load and release antimicrobial agents, but these approaches are generally limited to the use of hydrophobic agents that are soluble in the infused oily phases. Here, we report the design of so-called "proto-SLIPS" that address this limitation and permit the release of highly water-soluble (or oil-insoluble) agents.

Purpose: Gadoxetic acid-enhanced hepatobiliary phase T-weighted (Tw) MRI is effective for the detection of focal liver lesions but lacks sufficient T contrast to distinguish benign from malignant lesions. Although the addition of T, diffusion, and dynamic contrast-enhanced Tw imaging improves lesion characterization, these methods often do not provide adequate spatial resolution to identify subcentimeter lesions. This work proposes a high-resolution, volumetric, free-breathing liver MRI method that produces colocalized fat-suppressed, variable Tw images from a single acquisition, thereby improving both lesion detection and characterization.

Purpose: Speech disfluencies are common in individuals who do not stutter, with estimates suggesting a typical rate of six per 100 words. Factors such as language ability, processing load, planning difficulty, and communication strategy influence disfluency. Recent work has indicated that bilinguals may produce more disfluencies than monolinguals, but the factors underlying disfluency in bilingual children are poorly understood.

Introduction: The local perception of a stimulus such as wounding can trigger plant-wide responses through the propagation of systemic signals including the vascular transport of diverse chemical messengers, the propagation of electrical changes, and even potentially hydraulic waves that rapidly spread throughout the plant body. These systemic signals trigger changes in second messengers such as Ca2+ that then play roles in triggering subsequent molecular responses. Although the glutamate receptor-like (GLR) channels GLR3.
