Gap Junctions01:37

Gap Junctions

57.3K
Multicellular organisms employ a variety of ways for cells to communicate with each other. Gap junctions are specialized proteins that form pores between neighboring cells in animals, connecting the cytoplasm between the two, and allowing for the exchange of molecules and ions. They are found in a wide range of invertebrate and vertebrate species, mediate numerous functions including cell differentiation and development, and are associated with numerous human diseases, including cardiac and...

Gap Junctions

9.7K
The cytoplasm of adjacent animal cells can exchange small molecules, ions, and secondary messengers via the communication channels which form the gap junctions. These junctions comprise a few hundred to thousands of molecular channels, each made of two halves, called the connexon hemichannel. A connexon is a hexamer of six transmembrane connexin proteins, which assemble radially, thus forming a pore or channel in the center. One connexon hemichannel docks with a corresponding connexon on the...

Health Literacy

5.4K
Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...

Concepts of Health and Illness

18.2K
Health is a condition of the body, mind, and spirit where an individual remains free from illness. Similarly, wellness is an active state, including living a lifestyle that promotes physical, mental, and emotional health. Physical health is critical for the overall well-being and can be affected by lifestyle, activity level, diet, and behavior. The highest attainable standard of health is a fundamental and universal human right. Consider Lisa, a fifteen-year-old born with congenital...

Summary

Racial and ethnic disparities in well-being among older Americans are substantial and greater than previously measured. Most gaps originate from initial conditions before age 60, not later-life factors.

Area of Science:

  • Gerontology
  • Health Economics
  • Sociology of Aging

Background:

  • Racial and ethnic disparities persist in the well-being of older Americans.
  • Existing welfare metrics may underestimate the full extent of these inequalities.

Purpose of the Study:

  • To estimate racial and ethnic disparities in overall well-being among older Americans.
  • To identify the primary drivers of these disparities over the life course.

Main Methods:

  • Utilized longitudinal data and an expected utility framework.
  • Incorporated measures of consumption, leisure, health, mortality, and wealth.
  • Performed decomposition analyses and counterfactual simulations.

Main Results:

  • Racial and ethnic inequality in well-being is more pronounced than suggested by consumption or life expectancy alone.
  • A majority of welfare gaps are attributable to initial conditions at age 60.
  • Addressing late-life health factors like hypertension or diabetes had minimal impact on overall gaps.

Conclusions:

  • Early life interventions are likely more effective for closing racial and ethnic well-being gaps in later life.
  • Policies targeting disparities should consider the cumulative impact of factors throughout the life cycle.
