Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

115
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

Biological Clocks and Seasonal Responses02:45

Biological Clocks and Seasonal Responses

35.0K
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Circadian Rhythms and Gene Regulation

4.1K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Threats to Biodiversity

22.7K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Optimal Foraging00:48

Optimal Foraging

12.4K
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Predator-Prey Interactions02:39

Predator-Prey Interactions

18.5K
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

Summary

Daylight saving time shifts human activity earlier, potentially harming health. However, this shift may reduce deer-vehicle collisions, benefiting wildlife safety.

Area of Science:

  • Environmental Science
  • Wildlife Ecology
  • Public Health

Background:

  • Daylight saving time (DST) alters human activity patterns relative to natural light cycles.
  • Human health and safety are demonstrably affected by these shifts.
  • The impact of DST on wildlife, particularly deer, remains less understood.

Purpose of the Study:

  • To investigate the potential benefits of earlier human activity, as influenced by DST, on deer-vehicle collision (DVC) rates.
  • To explore the ecological implications of human-induced temporal shifts on wildlife-human interactions.

Main Methods:

  • Utilized existing data on DST implementation and deer-vehicle collision statistics.
  • Employed predictive modeling to assess the relationship between altered human activity schedules and DVC frequency.
  • Analyzed temporal patterns of human activity and deer movement.

Main Results:

  • A projected decrease in deer-vehicle collisions is associated with earlier human activity due to DST.
  • The findings suggest a potential safety benefit for deer populations during DST periods.
  • The study highlights an indirect positive ecological consequence of DST.

Conclusions:

  • Earlier human activity, a consequence of daylight saving time, may paradoxically enhance deer safety by reducing vehicle collisions.
  • This research underscores the complex and sometimes unexpected interactions between human behavior, environmental changes, and wildlife.
  • Further investigation into DST's broader ecological impacts on wildlife is warranted.
