AI Article Synopsis

  • The study examined how well Peak Nasal Inspiratory Flow (PNIF) and Peak Nasal Expiratory Flow (PNEF) can predict nasal obstruction symptoms in individuals.
  • In a sample of 131 participants, those without allergic rhinitis had higher PNIF and PNEF values compared to those with symptoms.
  • The research found specific threshold values for PNIF and PNEF that indicate potential nasal obstruction, suggesting these measures can help assess and screen for nasal problems effectively.

Article Abstract

Objective: The aim of this study was to investigate the ability of Peak Nasal Inspiratory Flow (PNIF) and Peak Nasal Expiratory Flow (PNEF) measures to predict symptoms of nasal obstruction.

Methods: This is a cross-sectional study, carried out in 131 individuals (64 with symptomatic allergic rhinitis and 67 asymptomatic) aged between 16 and 50 years.

Results: PNIF and PNEF were higher among non-rhinitis. In the curve analysis (receiver operating characteristic), a value of 115 was found for PNIF with a sensitivity of 98.4% and specificity of 87.5% (AUC = 0.99, p < 0.001) and 165 in PNEF with a sensitivity of 65.7% and specificity of 85.1% (AUC = 0.92, p < 0.001).

Conclusions: PNIF and PNEF values were lower in patients with AR compared to asymptomatic cases. Our findings present reference values of PNIF and PNEF in the evaluation of nasal obstruction symptoms and reinforce the importance to complement more refined assessment of patients' symptoms. PNEF can be a valuable tool in screening patients and to complement PNIF measurement.

Tracing the change of the volatile compounds of soy sauce at different fermentation times by PTR-TOF-MS, -nose and GC-MS.

Food Chem X

Guangdong Provincial Key Laboratory of Nutraceuticals and Functional Foods, College of Food Sciences, South China Agricultural University, Guangzhou, Guangdong 510642, China.

Proton-transfer reaction time-of-flight mass spectrometry (PTR-TOF-MS), combined with electronic nose (-nose), was first used to track the change of volatile organic compounds (VOCs) in soy sauce in this study. The results showed that 163 VOCs with different mass numbers were identified. Based on the differences in VOCs, the entire fermentation cycle was divided into four stages (0D and 15D; 30D-75D; 90D; 105D-120D).

Neural processing of auditory stimuli in rats: translational aspects using auditory oddball paradigms.

Behav Brain Res

January 2025

Background: The three-class oddball paradigm allows to investigate the processing of behaviorally relevant and irrelevant auditory stimuli. In humans, event-related potentials (ERPs) are used as neural correlate of behavior. We recorded local field potentials (LFPs) within the medial prefrontal cortex (mPFC) in rats during three-class and passive two-class oddball paradigms and analyzed the ERPs focusing on similarities to human recordings.

Consequences of weaning and separation for feed intake and milking characteristics of dairy cows in a cow-calf contact system.

Department of Applied Animal Science and Welfare, Swedish University of Agricultural Sciences, 750 07 Uppsala, Sweden; The Beijer Laboratory for Animal Science, Faculty for Vet. Med. and Animal Science, SLU, 750 07 Uppsala, Sweden.

In cow-calf contact (CCC) systems breaking the maternal bond may induce stress for the cow, thereby affecting feed intake, milk yield, milk flow rate, and milk electrical conductivity. This study aimed to determine the consequences of weaning and separation strategies in CCC systems for feed intake and milking characteristics of the cow. In 2 experiments, Swedish Holstein and Swedish Red cows either had (experiment 1) whole-day CCC (CCC1, n = 12) for 8.

Background: NSAID-exacerbated respiratory disease (N-ERD) is a hypersensitivity to non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin or ibuprofen, accompanied by chronic rhinosinusitis (with or without nasal polyps) or asthma. The prevalence of hypersensitivity to NSAIDs is estimated to be 2%. The first line of treatment is the avoidance of NSAIDs.
