Summary
Genetic variations in CLOCK, NPSR1, and SLC6A3 genes are linked to traffic accidents in bus drivers. These genetic factors may influence chronotype, sleep resistance, and cognitive control, impacting driving safety.
Area of Science:
- Occupational Health
- Genetics
- Transportation Safety
Background:
- Bus driving demands sustained attention, cognitive function, and resilience to sleep disruption.
- Research is exploring genetic factors influencing these critical traits in professional drivers.
- Understanding these links can enhance road safety strategies.
Purpose of the Study:
- To investigate associations between single nucleotide polymorphisms (SNPs) and traffic accident history in professional bus drivers.
- To identify specific genes potentially related to accident risk in this high-responsibility profession.
Main Methods:
- Genotyping of polymorphisms in genes related to circadian rhythm (CLOCK, RORA, NPAS2, NPSR1, PER3), cognitive, and emotional functions (DRD3, SLC6A3, DBH).
- Analysis of associations between identified SNPs and traffic crash parameters in 299 professional bus drivers with accident histories.
Main Results:
- Significant associations were found between polymorphisms in CLOCK, NPSR1, and SLC6A3 genes and traffic crash parameters.
- CLOCK gene polymorphisms may relate to chronotype and sleep deprivation resistance.
- NPSR1 and SLC6A3 polymorphisms might be associated with cognitive and emotional control relevant to driving.
Conclusions:
- Specific genetic variations in CLOCK, NPSR1, and SLC6A3 are potentially linked to traffic accident risk in bus drivers.
- These findings suggest a genetic basis for individual differences in chronotype, sleep resilience, and cognitive control affecting driving safety.
- Further research can explore targeted interventions based on genetic predispositions to improve bus driver safety.

Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

01:24Bus Impedance Matrix
527
Calculating subtransient fault currents for three-phase faults in an N-bus power system involves using the positive-sequence network. When a three-phase short circuit occurs at a specific bus, the analysis uses the superposition method to evaluate two separate circuits.
In the first circuit, all machine voltage sources are short-circuited, leaving only the prefault voltage source at the fault location. The positive-sequence bus impedance matrix can be determined by solving the nodal equations,...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

01:13Insufficient Sleep and Sleep Deprivation
932
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
