AI Article Synopsis
- The study investigates how retinol acid (RA) and triiodothyronine (T3) can help improve cognitive function affected by sleep deprivation (SD) in rats.
- Four groups of male Wistar rats were tested: a control group, a sleep deprivation group, and two groups that received RA or T3 after being sleep deprived.
- Results showed that both RA and T3 significantly improved behavior and brain function measured in the hippocampus, suggesting they can counteract the negative effects of sleep deprivation on the nervous system.
Article Abstract
Objective: To explore the effects of retinol acid (RA) and triiodothyronine (T3) on alleviating the impairment of cognitive function by sleep deprivation (SD).
Methods: Male Wistar rats were divided into 4 groups: control group (C group), sleep deprivation group (SD group), sleep deprivation + RA group (SD + RA group) and sleep deprivation + T3 group (SD + T3 group). Open field test (OFT) was used to observe the nervous behavior of the rats after SD and electrophysiological brain stereotactic method was used to test long-term potentiation (LTP) in dentate gyrus (DG) of the rats. Ng protein expression was determined by Western blot.
Results: Compared with the SD group, the number of crossing in OFT, the changes of amplitude of population spike (PS) and the expression of Ng protein in hippocampus were higher significantly in the SD + RA and SD + T3 groups. All of these had not significant difference comparing with the C group.
Conclusion: RA and T3 may alleviate the restrain state of neural system after SD by augmenting the expression of Ng protein in hippocampus.

A female NCAA Division I track athlete experienced non-localized shin pain midway through her first season, which was diagnosed as medial tibial stress syndrome. Treatments included strengthening and range of motion exercises, reduced training volume, and pain control modalities, but symptoms worsened. It was revealed she had been suffering from severe sleep deprivation (<3 hours/night) contributing to bilateral tibial and fibular stress reactions.

Adolescents in affluent nations have experienced a decline in sleep duration, associated with adverse outcomes such as behavioral issues and health concerns. However, the connection between sleep and mental well-being during adolescence, particularly in developing regions like rural China, remains underexplored. A cross-sectional study of 18,516 adolescents in 124 junior high schools in Ningxia, China, utilized the strengths and difficulties questionnaire to assess mental health.

Objective: This study investigated the effects of sleep deprivation (SD) on balance after normal sleep, 24 h of SD, and subsequent rest under eyes-open (EO) and eyes-closed (EC) conditions. Our aim was to ascertain whether the reduced efficiency of balance control following SD is generalized or selective.

Transcutaneous auricular vagus nerve stimulation (taVNS) has garnered increasing attention as a safe and effective peripheral neuromodulation technique in various clinical and cognitive neuroscience fields. However, there is ongoing debate about whether the commonly used earlobe control interferes with the objective assessment of taVNS regulatory effects. This study aims to further explore the regulatory effects of taVNS and earlobe stimulation (ES) on alertness levels and physiological indicators following 24 h of sleep deprivation (SD), based on previous findings that both taVNS and ES showed significant positive effects.

Purpose: It is presumed by many that acute sleep loss results in degraded in-game esports (competitive, organized video game play) performance. However, this has not been experimentally investigated to date. The objective of the current experiment was to elucidate whether ~29hrs of total sleep deprivation impacts in-game performance for the popular esport
