Nicotinamide Phosphoribosyltransferase Acetylation Mediating Muscle Dysfunction Contributes to Sleep Apnoea in Obesity

Journal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 1, February 2025.
ABSTRACT Background Obstructive sleep apnoea (OSA) occurs frequently among individuals with obesity, which is attributed to upper airway muscle dysfunction. Muscle function is regulated by the dynamic balance of the nicotinamide adenine dinucleotide (NAD+) and its reduced form (NADH), which is controlled by the enzyme nicotinamide ...

Detection of speech events and speaker characteristics through photo-plethysmographic signal neural processing [PDF]

arXiv, 2019
The use of photoplethysmogram signal (PPG) for heart and sleep monitoring is commonly found nowadays in smartphones and wrist wearables. Besides common usages, it has been proposed and reported that person information can be extracted from PPG for other uses, like biometry tasks.

Effectiveness of peer‐delivered sleep health education and social support in increasing OSA evaluation among at‐risk blacks

Journal of Sleep Research, Volume 34, Issue 1, February 2025.
Summary To assess the effectiveness of culturally and linguistically tailored, peer‐delivered obstructive sleep apnea education and of social support to increase adherence to physician‐recommended obstructive sleep apnea evaluation among blacks. In a two‐arm randomised controlled trial, we ascertained the effectiveness of peer‐delivered obstructive ...

Respiratory Monitoring Based on Tracheal Sounds: Continuous Time-Frequency Processing of the Phonospirogram Combined with Phonocardiogram-Derived Respiration

Sensors, 2020
Patients with central respiratory paralysis can benefit from diaphragm pacing to restore respiratory function. However, it would be important to develop a continuous respiratory monitoring method to alert on apnea occurrence, in order to improve the ...

Effect of respiratory-induced intensity variations on finger SpO(2) measurements in volunteers [PDF]

, 2013
Photoplethysmographic (PPG) signals were recorded from the fingers of 16 healthy volunteers with periods of timed and forced respiration. The aim of this pilot study was to compare estimations of arterial oxygen saturation (SpO2) recorded using a ...

tVNS alters inflammatory response in adult VPA‐induced mouse model of autism: evidence for sexual dimorphism

FEBS Open Bio, Volume 15, Issue 1, Page 69-80, January 2025.
Cytokine levels in adult valproic acid (VPA)‐induced mouse (C57BL6) model of autism has been investigated and found to be altered. We show that bilateral transcutaneous auricular vagus nerve stimulation (tVNS) altered the inflammatory response and increased brain NLPR3 levels.

Dissecting the role of TRPV1 in detecting multiple trigeminal irritants in three behavioral assays for sensory irritation [v1; ref status: indexed, http://f1000r.es/p8]

F1000Research, 2013
Polymodal neurons of the trigeminal nerve innervate the nasal cavity, nasopharynx, oral cavity and cornea. Trigeminal nociceptive fibers express a diverse collection of receptors and are stimulated by a wide variety of chemicals.

Regulatory T Cell Phenotype Related to Cytokine Expression Patterns in Post‐COVID‐19 Pulmonary Fibrosis and Idiopathic Pulmonary Fibrosis

Immunity, Inflammation and Disease, Volume 13, Issue 1, January 2025.
A variety of immune cells are involved in the development and progression of pulmonary fibrosis confirming an immunological similarity between idiopathic pulmonary fibrosis and post‐COVID‐19 lung fibrosis (PCLF). T‐reg cells play a key role in the worsening of the disease.
