Biological Clocks and Seasonal Responses02:45

Biological Clocks and Seasonal Responses

36.4K
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...

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

116
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...

Introduction to Biological Bases of Psychology

3.5K
Biopsychology serves as a vital bridge connecting the intricate domains of biology and psychology, shedding light on how biological systems influence psychological phenomena. This field scrutinizes the biological substrates of behavior and mental processes, emphasizing the nervous system along with the roles of neurotransmitters, hormones, and genetics. It also incorporates evolutionary perspectives to explain the adaptive nature of mental functions.
The nervous system, the cornerstone of...

Area of Science:

  • Forensic Science
  • Chronobiology
  • Molecular Biology

Background:

  • Biological clocks regulate essential physiological processes in living organisms.
  • Forensic investigations require scientific evidence to establish death circumstances and victim identity.
  • Understanding biological rhythms is crucial for both life and post-mortem analysis.

Purpose of the Study:

  • To review the association between molecular mechanisms of biological rhythms and forensically relevant aspects.
  • To explore the potential of biological clocks as tools in forensic investigations.
  • To contextualize the known effects of biological rhythms for forensic applications.

Main Methods:

  • Literature review summarizing existing research on biological rhythms.
  • Analysis of molecular mechanisms underlying biological clocks.
  • Correlation of biological rhythm data with forensic parameters.

Main Results:

  • Biological rhythms influence various life functions and persist to some extent after death.
  • Molecular clock mechanisms show potential for estimating post-mortem interval and cause of death.
  • Biological rhythms can provide insights into victim demographics like age, sex, and ethnicity.

Conclusions:

  • Biological rhythms represent a promising, yet underutilized, area for forensic science.
  • Mechanistic investigations of biological clocks can enhance personal identification and post-mortem interval determination.
  • Further research into molecular clock applications can significantly advance forensic investigations.
