Nanoplastic release from disposable plastics: Correlation with maximum service temperature.

The potential for bioaccumulation of nanoplastics (NPs, <1 µm) increases as the particle size decreases. Since several disposable plastic products used daily may release NPs, their intake may be unavoidable. Therefore, it is crucial to examine the release patterns of NPs from these products.

Oral subacute polypropylene microplastics administration effect on potential immunotoxicity in ICR mice.

Exposure to microplastics may be associated with damage of immune system. Polypropylene microplastics (PP-MPs) with a wide range of beneficial applications have not been extensively studied with respect to the immune system. The aim of this investigation is to examine the influence of two different sizes of PP-MPs (5.

Standardized Behavioral Treatment Improves Chronic Cough.

Objectives: Neurogenic Laryngeal Hypersensitivity (NLH) refers to a constellation of upper airway symptoms thought to be caused by a disturbance in afferent and/or efferent neural pathways creating an exaggerated hypersensitive laryngeal response. There is evidence to support behavioral therapy as treatment for improving symptoms from laryngeal motor dysfunction to sensory disturbance. This study aims to determine if there is significant symptomatic improvement in patients with NLH who received non-pharmacologic behavioral treatment performed by trained SLPs.

Applications of Telemedicine in Speech-Language Pathology: Evaluation of Patient Satisfaction.

Objectives: The study aimed to evaluate patient satisfaction with speech-language therapy televisits and to identify factors influencing the level of satisfaction.

Methods: Participants were recruited from an academic tertiary voice and swallowing center who had completed ≥1 telehealth session of speech-language therapy with a speech-language pathologist between March, 2020 and April, 2021. Patient satisfaction was assessed using the Short Assessment of Patient Satisfaction (SAPS), a validated 7-item survey.

Analysis of polysomnogram findings in children with concurrent obstructive and central sleep apnea.

Objective: Increasing evidence suggests overlap in mechanisms of obstructive and central sleep apnea. Our objective was to compare the patient characteristics and polysomnographic findings of children with concurrent obstructive and central sleep apnea (obstructive sleep apnea + central sleep apnea [OSA + CSA]), to those with OSA only.

Methods: A retrospective case series of polysomnogram (PSG) from 30 June 2013 to 30 June 2018 of patients 18 years and younger was performed.

Predictive values of static endoscopic evaluation of swallowing in adults.

Objective: Static endoscopic evaluation of swallowing (SEES) is an instrumental evaluation developed for in-office identification of patients who may benefit from a modified barium swallow study (MBSS). We aim to determine the predictive value of SEES for evaluating dysphagia.

Methods: A retrospective case series was performed on adults evaluated for dysphagia using SEES followed by MBSS at a single tertiary care center.

Evolution of telomere maintenance and tumour suppressor mechanisms across mammals.

Mammalian species differ dramatically in telomere biology. Species larger than 5-10 kg repress somatic telomerase activity and have shorter telomeres, leading to replicative senescence. It has been proposed that evolution of replicative senescence in large-bodied species is an anti-tumour mechanism counteracting increased risk of cancer due to increased cell numbers.

Sensitivity of primary fibroblasts in culture to atmospheric oxygen does not correlate with species lifespan.

Differences in the way human and mouse fibroblasts experience senescence in culture had long puzzled researchers. While senescence of human cells is mediated by telomere shortening, Parrinello et al. demonstrated that senescence of mouse cells is caused by extreme oxygen sensitivity.
