First Law of Thermodynamics00:37

First Law of Thermodynamics

66.4K
The First Law of Thermodynamics states that energy cannot be created or destroyed, only transformed. This can be demonstrated within a classic food web where light energy from the sun is harnessed as radiant energy by plants, converted into chemical energy, and stored as complex carbohydrates. The vegetation is then consumed by animals and during the digestion process, the sugars release energy as heat. The sugars also produce chemical energy that either gets used up doing work, stored in...

First Law of Thermodynamics

A change in the internal energy of a system depends on the the net heat transfer into the system and the net work done by the system. The first law of thermodynamics, which is a generalized form of energy conservation, relates these three quantities mathematically. It states that the change in the internal energy equals the difference between the heat transfer and work done by the system.
The applied heat increases the internal energy of a system. Hence, conventionally heat is considered...

Mechanisms of Heat Transfer II

4.5K
In convection, thermal energy is carried by the large-scale flow of matter. Ocean currents and large-scale atmospheric circulation, which result from the buoyancy of warm air and water, transfer hot air from the tropics toward the poles and cold air from the poles toward the tropics. The Earth’s rotation interacts with those flows, causing the observed eastward flow of air in the temperate zones. Convection dominates heat transfer by air, and the amount of available space for the airflow...

Mechanism of heat transfer

2.3K
Understanding heat transfer mechanisms is essential for understanding how our bodies maintain balance in different environmental conditions. When the environment is thermoneutral, the body is in a state of balance, neither using nor releasing energy to maintain its core temperature. However, when the environment is not thermoneutral, the body employs four heat transfer mechanisms to maintain homeostasis: conduction, convection, evaporation, and radiation. These mechanisms facilitate heat...

Area of Science:

  • Physiology
  • Metabolic Science
  • Endocrinology

Background:

  • Thermoregulation is vital for birds and mammals, with non-shivering thermogenesis (NST) driven by brown adipose tissue (BAT) playing a key role.
  • BAT thermogenesis is regulated centrally and peripherally, involving hypothalamic pathways like AMP-activated protein kinase (AMPK) and endoplasmic reticulum (ER) stress.

Purpose of the Study:

  • To review the mechanisms of NST, including UCP1-dependent and alternative pathways.
  • To explore the role of BAT in tumor biology and potential therapeutic applications.

Main Methods:

  • Literature review of recent research on NST and BAT.
  • Analysis of UCP1-dependent thermogenesis, creatine cycling, calcium-dependent thermogenesis, and lipid cycling.
  • Examination of BAT's role in modulating tumor metabolism.

Main Results:

  • BAT thermogenesis involves complex hormonal and central regulatory pathways.
  • Alternative NST pathways beyond UCP1 are being identified.
  • BAT shows potential for therapeutic interventions in metabolic and oncological diseases.

Conclusions:

  • Targeting BAT thermogenesis presents promising therapeutic strategies for obesity and cancer.
  • Further research into BAT mechanisms can unlock novel treatments for metabolic and oncological conditions.
