Identifying Obstructive Sleep Apnea Syndrome‐Associated Genes and Pathways through Weighted Gene Coexpression Network Analysis

Computational and Mathematical Methods in Medicine, Volume 2022, Issue 1, 2022., 2022
Background. Obstructive sleep apnea syndrome (OSAS) is the most common type of sleep apnea disorder. The disease seriously affects the patient’s respiratory system. At present, the prognosis of the disease is poor and there is a lack of effective treatments. Therefore, it is urgent to explore its pathogenesis and treatment methods. Method.

Assessment of left ventricular twist by 3D ballistocardiography and seismocardiography compared with 2D STI echocardiography in a context of enhanced inotropism in healthy subjects

Scientific Reports, 2021
Ballistocardiography (BCG) and Seismocardiography (SCG) assess the vibrations produced by cardiac contraction and blood flow, respectively, by means of micro-accelerometers and micro-gyroscopes.

A unified methodology for heartbeats detection in seismocardiogram and ballistocardiogram signals [PDF]

, 2020
This work presents a methodology to analyze and segment both seismocardiogram (SCG) and ballistocardiogram (BCG) signals in a unified fashion. An unsupervised approach is followed to extract a template of SCG/BCG heartbeats, which is then used to fine ...

Mechanical deconditioning of the heart due to long-term bed rest as observed on seismocardiogram morphology

npj Microgravity, 2022
During head-down tilt bed rest (HDT) the cardiovascular system is subject to headward fluid shifts. The fluid shift phenomenon is analogous to weightlessness experienced during spaceflight microgravity.
