Quantification of Sleep Fragmentation Through the Analysis of Sleep-Stage Transitions [PDF]

open access: yesarXiv, 2003
We introduce new quantitative approaches to study sleep-stage transitions with the goal of addressing the two following questions: (i) Can the new approaches provide more information on the structure of sleep-stage transitions? (ii) How does sleep fragmentation in patients with sleep apnea affect the structure of sleep-stage transitions?

A Knowledge Distillation Framework For Enhancing Ear-EEG Based Sleep Staging With Scalp-EEG Data [PDF]

open access: yesarXiv, 2022
Sleep plays a crucial role in the well-being of human lives. Traditional sleep studies using Polysomnography are associated with discomfort and often lower sleep quality caused by the acquisition setup. Previous works have focused on developing less obtrusive methods to conduct high-quality sleep studies, and ear-EEG is among popular alternatives ...

A study on sleep stage change and REM sleep

open access: yesJournal of Advanced Science, 1998
Relationship between sleep stage change and REM sleep was examined using polysomnography. EEG, EMG and EOG measured in normal and sleep deprived condition were analyzed. REM sleep was classified in two states with and without rapid eye movement (REM(+), REM(-) respectively). The quantity of REM(+) was decreased in sleep deprived condition.

Changes of sleep-stage transitions due to ageing and sleep disorder [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015
Transition patterns between different sleep stages are analysed in terms of probability distributions of symbolic sequences for young and old subjects with and without sleep disorder. Changes of these patterns due to ageing are compared with variations of transition probabilities due to sleep disorder.

Labile sleep promotes awareness of abstract knowledge in a serial reaction time task

open access: yesFrontiers in Psychology, 2015
Sleep has been identified as a critical brain state enhancing the probability of gaining insight into covert task regularities. Both non-rapid eye movement (NREM) and REM sleep have been implicated with offline re-activation and reorganization of ...

Effectiveness of a Telephone‐Delivered Walk With Ease Program on Arthritis‐Related Symptoms, Function, and Activity: A Randomized Trial

open access: yesArthritis Care &Research, EarlyView.
Objective Walk With Ease (WWE) is a six‐week arthritis‐appropriate evidence‐based physical activity program traditionally offered in a face‐to‐face format. Because many populations encounter participation barriers to in‐person programs, WWE was modified for telephone delivery (WWE‐T).

Extracting continuous sleep depth from EEG data without machine learning [PDF]

open access: yesarXiv, 2023
The human sleep-cycle has been divided into discrete sleep stages that can be recognized in electroencephalographic (EEG) and other bio-signals by trained specialists or machine learning systems. It is however unclear whether these human-defined stages can be re-discovered with unsupervised methods of data analysis, using only a minimal amount of ...

Longitudinal Relationship Between Pain and Depression in People With Inflammatory Arthritis: A Narrative Review

open access: yesArthritis Care &Research, EarlyView.
As many patients with inflammatory arthritis (IA) have chronic pain, understanding how to best assess and manage pain in IA is a priority. Comorbid depression is prevalent in adults with IA, affecting 15% to 39% of people. Although pain and depression are thought to be associated in IA, this concept is largely based on cross‐sectional data.

The Potential for Extracellular Vesicles in Nanomedicine: A Review of Recent Advancements and Challenges Ahead

open access: yesAdvanced Biology, EarlyView.
Extracellular vesicles (EVs) play a dual role in diagnostics and therapeutics, offering innovative solutions for treating cancer, cardiovascular, neurodegenerative, and orthopedic diseases. This review highlights EVs’ potential to revolutionize personalized medicine through specific applications in disease detection and treatment.

Permutation time irreversibility in sleep electroencephalograms: Dependence on sleep stage and the effect of equal values [PDF]

open access: yesYao, WP. Permutation time irreversibility in sleep electroencephalograms: Dependence on sleep stage and the effect of equal values. Physical Review E, 2024, 109(5): 054104
Time irreversibility (TIR) refers to the manifestation of nonequilibrium brain activity influenced by various physiological conditions; however, the influence of sleep on electroencephalogram (EEG) TIR has not been sufficiently investigated. In this paper, a comprehensive study on permutation TIR (pTIR) of EEG data under different sleep stages is ...
