The intensities of vowels and plosive bursts and their impact on text intelligibility in singinga).

In classical singing, there are often problems with the intelligibility of sung text. The present study aims to test the hypotheses that (1) in loud operatic singing, compared with speaking, the intensity of voiceless plosives increases less than the intensity of vowels, leading to poorer recognition of plosives; and (2) pronouncing the plosive bursts with greater intensity improves their recognition. The acoustic analysis of nine opera arias in Italian from the Classical and Romantic periods performed by ten classically trained singers showed that the average difference in the intensity of vowels when sung and spoken was 14.

An integrated organoid omics map extends modeling potential of kidney disease.

Kidney organoids are a promising model to study kidney disease, but their use is constrained by limited knowledge of their functional protein expression profile. Here, we define the organoid proteome and transcriptome trajectories over culture duration and upon exposure to TNFα, a cytokine stressor. Older organoids increase deposition of extracellular matrix but decrease expression of glomerular proteins.

CD4 T cells produce GM-CSF and drive immune-mediated glomerular disease by licensing monocyte-derived cells to produce MMP12.

The study also aimed to identify any differences in HRV while competing at home or away. Data collection covered an entire collegiate season, commencing in the preseason and concluding upon elimination from the NCAA Soccer tournament.

Urinary tract infection pocket card effect on preferred antimicrobial prescribing for cystitis among patients discharged from the emergency department.

Purpose: To evaluate the impact of a urinary tract infection (UTI) pocket card on preferred antibiotic prescribing for patients discharged from the emergency department (ED) with a diagnosis of cystitis.

Methods: A multicenter, retrospective, pre-post study was conducted to compare outcomes following the introduction of a UTI pocket card. The primary outcome was prescribing rates for institutional first-line preferred antibiotics (cephalexin and nitrofurantoin) versus other antimicrobials for cystitis.

Prediction of in vivo supersaturation and precipitation of poorly water-soluble drugs: Achievements and aspirations.

This review focuses on options available to a pharmaceutical scientist to predict in vivo supersaturation and precipitation of poorly water-soluble drugs. As no single device or system can simulate the complex gastrointestinal environment, a combination of appropriate in vitro tools may be utilized to get optimal predictive information. To address the empirical issues encountered during small-scale and full-scale in vitro predictive testing, theoretical background and relevant case studies are discussed.

Detection of Bulbar Involvement in Patients With Amyotrophic Lateral Sclerosis by Machine Learning Voice Analysis: Diagnostic Decision Support Development Study.

Background: Bulbar involvement is a term used in amyotrophic lateral sclerosis (ALS) that refers to motor neuron impairment in the corticobulbar area of the brainstem, which produces a dysfunction of speech and swallowing. One of the earliest symptoms of bulbar involvement is voice deterioration characterized by grossly defective articulation; extremely slow, laborious speech; marked hypernasality; and severe harshness. Bulbar involvement requires well-timed and carefully coordinated interventions.

Decoding of facial expressions of pain in avatars: does sex matter?

Objectives: The decoding of facial expressions of pain plays a crucial role in pain diagnostic and clinical decision making. For decoding studies, it is necessary to present facial expressions of pain in a flexible and controllable fashion. Computer models (avatars) of human facial expressions of pain allow for systematically manipulating specific facial features.

Multi-centered evaluation of a novel fixed-dose four-factor prothrombin complex concentrate protocol for warfarin reversal.

Introduction: Previous studies have shown fixed-dose 4PCC to be as effective as standard-dose 4PCC for warfarin reversal. However, certain patient populations such as those with high total body weight (TBW) or elevated baseline INR may be at increased risk for treatment failure. The purpose of this study was to validate the efficacy of a novel fixed-dose 4PCC protocol for warfarin reversal.
