Introduction Circadian rhythms, which control sleep-wake cycles and metabolism, are fundamental to human health. Our study aimed to understand how these rhythms affect proteins in the body throughout the day, and to develop a tool that predicts the body's internal clock phase based on protein expression. Methods Plasma samples from 17 healthy adul...

Purpose: Early school start times could adversely impact adolescent sleep duration. They could also impact other behaviors like diet and physical activity, either directly or indirectly through effects on sleep. We examined whether the double school shift system was associated with sleep, diet, and physical activity behaviors among Mexican adolesce...

Objectives: To explore how the blood plasma proteome fluctuates across the 24-hour day and identify a subset of proteins that show endogenous circadian rhythmicity. Methods: Plasma samples from 17 healthy adults were collected hourly under controlled conditions de- signed to unmask endogenous circadian rhythmicity; in a subset of 8 participants, we...

Short sleep duration has been associated with poor diet quality in school-aged children in multiple populations. However, investigations of sleep and dietary quality in Mexican school-aged children are scarce. The main objective of this work was to assess the association between sleep duration and dietary quality in Mexican school-aged children str...

Working at night can lead to misalignment between the timing of the biological clock and the work/sleep schedule, resulting in sleepiness, inattention, and impaired performance during the night shift and poor quality, shortened sleep during the day. These adverse effects are reported to be worse in older workers due to their decreased ability to sl...

In today's ICT-based learning environment, students are expected to evaluate the structure of their courses and associated teaching methods.
