Mirrors and toothaches: commonplace manipulations of non-auditory feedback availability change perceived speech intelligibility.

This paper investigates the impact of two non-technical speech feedback perturbations outside the auditory modality: topical application of commercially-available benzocaine to reduce somatosensory feedback from speakers' lips and tongue tip, and the presence of a mirror to provide fully-detailed visual self-feedback. In experiment 1, speakers were recorded under normal quiet conditions (i.e.

Senolytics rejuvenate aging cardiomyopathy in human cardiac organoids.

Background: Human cardiac organoids closely replicate the architecture and function of the human heart, offering a potential accurate platform for studying cellular and molecular features of aging cardiomyopathy. Senolytics have shown potential in addressing age-related pathologies but their potential to reverse aging-related human cardiomyopathy remains largely unexplored.

Methods: We employed human iPSC-derived cardiac organoids (hCOs/hCardioids) to model doxorubicin(DOXO)-induced cardiomyopathy in an aged context.

Loop-Mediated Isothermal Amplification (LAMP): An Innovative Approach for the Environmental Monitoring of SARS-CoV-2.

The rapid and accurate detection of SARS-CoV-2 in environmental settings is crucial for effective public health management during the COVID-19 pandemic. This study compares the performance of the Reverse Transcription quantitative polymerase chain reaction (RT-qPCR) and the Reverse Transcription loop-mediated isothermal amplification (RT-LAMP) for SARS-CoV-2 detection from 100 surface samples collected in healthcare environments. The reference method, RT-qPCR, identified a percentage of 25% of positive samples, while RT-LAMP detected a percentage of 27% of positive surfaces.
