Body Temperature01:25

Body Temperature

4.7K
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Body Temperature

1.5K
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

Effects of Temperature on Free Energy02:11

Effects of Temperature on Free Energy

28.3K
The spontaneity of a process depends upon the temperature of the system. Phase transitions, for example, will proceed spontaneously in one direction or the other depending upon the temperature of the substance in question. Likewise, some chemical reactions can also exhibit temperature-dependent spontaneities. To illustrate this concept, the equation relating free energy change to the enthalpy and entropy changes for the process is considered:

Physical Methods for Controlling Microbial Growth: Temperature

1.1K
Heat is a widely used method to control microbial growth by targeting and denaturing cellular proteins, thereby killing or inactivating microbes. This method's effectiveness is quantified using parameters such as the thermal death point (TDP), thermal death time (TDT), and decimal reduction time (D value). TDP represents the lowest temperature at which all microorganisms in a liquid suspension are eliminated within 10 minutes, whereas TDT is the time necessary to achieve sterilization at a...

Increased Body Temperature01:25

Increased Body Temperature

7.5K
A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Area of Science:

  • Biomedical Engineering
  • Medical Imaging
  • Thermosensing

Background:

  • Accurate temperature estimation in tissues is crucial for various medical applications.
  • Existing fat-referenced proton resonance frequency shift (PRFS) methods have limitations in accuracy and precision for fat-containing tissues.

Purpose of the Study:

  • To propose and evaluate a dual-step iterative temperature estimation (DITE) method.
  • To improve the accuracy and precision of temperature measurements in fat-containing tissues.

Main Methods:

  • Utilized a fat-water signal model with multiple fat peaks for simultaneous estimation.
  • Implemented DITE with alternating 2-step minimizations and temperature map smoothing.
  • Evaluated performance using Monte Carlo simulations, fat/water phantoms, and ex vivo brown adipose tissue experiments.

Main Results:

  • DITE demonstrated improved accuracy and precision compared to previous PRFS methods in phantom experiments.
  • In brown adipose tissue, DITE achieved an average mean error of -0.08°C, SD of 0.46°C, and RMS error of 0.56°C.

Conclusions:

  • The proposed DITE method significantly enhances temperature measurement accuracy and precision.
  • DITE is a simple and effective fat-referenced thermometry method for tissues with 20-80% fat fractions and smooth temperature profiles.
