RNA Stability01:53

RNA Stability

35.8K
Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

DNA Helicases00:55

DNA Helicases

24.2K
DNA unwinding helicase enzymes are a type of motor protein. Motor proteins can translocate along filaments or polymers using energy generated from ATP hydrolysis. Helicases are involved in all the important cellular processes where DNA unwinding is required, such as DNA replication, repair, recombination, and transcription. They are present in all living organisms, but vary in their structure, function, and mechanism of action. For example, in prokaryotes, DnaB helicase binds and translocates...

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Summary

Many Canadian workers exposed to loud noise are vulnerable to hearing loss and tinnitus because hearing protection is not always required or used. This highlights potential gaps in workplace safety regulations and enforcement.

Area of Science:

  • Occupational Health
  • Audiology
  • Public Health Policy

Background:

  • Workplace safety legislation aims to protect employees from hazards like excessive noise.
  • Some workers in noisy environments are not mandated to use hearing protection, increasing their risk of hearing impairment and tinnitus.

Purpose of the Study:

  • To identify the prevalence of vulnerable workers exposed to loud workplace noise in Canada.
  • To examine the characteristics of workers not required to use hearing protection and their association with hearing difficulties.

Main Methods:

  • Analysis of data from the Canadian Health Measures Survey (2012-2015) for individuals aged 19-79 (n=6,571).
  • Definition of 'exposed to loud workplace noise' as needing to raise voice to communicate at arm's length.
  • Definition of 'vulnerable workers' as those not required to use hearing protection and using it rarely or never.

Main Results:

  • An estimated 11 million Canadians (43%) worked in noisy environments; over 6 million (56%) were classified as vulnerable.
  • Vulnerable workers, particularly women (72% of vulnerable women) and the self-employed, were more likely to report hearing difficulties and tinnitus.
  • Despite higher percentages, men represented a larger absolute number of vulnerable workers (3.7 million vs. 2.4 million women).

Conclusions:

  • A significant proportion of workers in noisy settings are vulnerable due to a lack of mandatory hearing protection use.
  • Further research is needed to determine if current health and safety legislation adequately addresses workplace noise exposure or if implementation is insufficient.
