Quaternary ammonium compounds (QACs) have served as essential antimicrobial agents for nearly a century due to their rapid membrane-disrupting action. However, the emergence of bacterial resistance and environmental concerns have driven interest in alternative designs, such as "soft QACs", which are designed for enhanced biodegradability and reduced resistance potential. In this study, we explored the antibacterial properties and mechanisms of action of our newly synthesized soft QACs containing a labile amide bond within a quinuclidine scaffold.

Purpose: Vericiguat, a soluble guanylate cyclase (sGC) stimulator, has been demonstrated effective in improving prognosis of patients with heart failure with reduced ejection fraction. However, there are limited data concerning the effect of vericiguat in patients with doxorubicin (DOX)-induced cardiomyopathy (DIC). In this study, we investigated the effects of vericiguat on cardiac structure and function in rats with DIC as well as their potential mechanisms of action.

Bee venom (BV) represents a promising natural alternative to conventional antibiotics, particularly significant given its broad-spectrum antimicrobial activity and potential to address the growing challenge of antimicrobial resistance. The prevalence of antimicrobial-resistant microorganisms (AMR) is a global burden that affects human health and the economies of different countries. As a result, several scientific communities around the world are searching for safe alternatives to antibiotics.

Unipolar brush cells (UBCs) are excitatory interneurons in the cerebellar cortex that receive mossy fiber (MF) inputs and excite granule cells. The UBC population responds to brief burst activation of MFs with a continuum of temporal transformations, but it is not known how UBCs transform the diverse range of MF input patterns that occur in vivo. Here, we use cell-attached recordings from UBCs in acute cerebellar slices to examine responses to MF firing patterns that are based on in vivo recordings.

Background: Fast-acting Sub-perception Therapy (FAST) is a novel spinal cord stimulation (SCS) modality delivering paresthesia-free pain relief. Our study evaluated the longer-term, real-world impact of FAST on chronic pain.
Research Design And Methods: As part of a multicenter, real-world, consecutive case series, we retrospectively identified patients who used FAST-SCS and analyzed their data.
