Department of Psychiatry, Korea University College of Medicine, Seoul, Republic of Korea.
Background: Insomnia is a prevalent sleep disorder affecting millions worldwide, with significant impacts on daily functioning and quality of life. While traditionally assessed through subjective measures such as the Insomnia Severity Index (ISI), the advent of wearable technology has enabled continuous, objective sleep monitoring in natural environments. However, the relationship between subjective insomnia severity and objective sleep parameters remains unclear.

Resveratrol, a natural polyphenol, has shown promising neuroprotective effects in several in vivo and in vitro experimental models. However, the mechanisms by which resveratrol mediates these effects are not fully understood. Glutamate is the major excitatory neurotransmitter in the brain; however, excessive extracellular glutamate levels can affect neural activity in several neurological diseases.

Cold stress (CS) is a significant natural hazard, and distinguishing between plant cold resistance and sensitivity is critical for cultivar breeding and the development of germplasm resources. This study used 205 tobacco (Nicotiana tabacum L.) varieties from around the world to investigate the changes in the chlorophyll a fluorescence (OJIP) transients, JIP-test parameters, and seedling growth caused by seven days of CS (5°C) treatment.

Institute for Occupational and Maritime Medicine (ZfAM), University Medical Center Hamburg-Eppendorf (UKE), Seewartenstraße 10, 20459 Hamburg, Hamburg, Germany.
Background: Seafarers are exposed to a variety of job-specific physical and psychosocial stressors. Health promotion on board is of great importance for the salutogenesis of this occupational group. Due to the difficult accessibility of seafarers, electronically supported health management can be highly valuable.

How this position is regulated and its role in genome photoprotection remains unknown. By developing a model of human keratinocytes internalizing extracellular melanin into pigment organelles, we show that keratin 5/14 intermediate filaments mechanically control the 3D perinuclear position of pigments, shielding DNA from photodamage.
