Regulation of Food Intake01:30

Regulation of Food Intake

3.1K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Target Cell Response to Hormones01:22

Target Cell Response to Hormones

6.1K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Hormones and Bone Tissue01:17

Hormones and Bone Tissue

4.2K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

327
Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

6.4K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Hormones Regulating Blood Glucose01:16

Hormones Regulating Blood Glucose

8.1K
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

Area of Science:

  • Endocrinology
  • Obesity Research
  • Nutritional Science

Background:

  • Dehydroepiandrosterone (DHEA) is known to decrease fat stores in rodent models of obesity.
  • Controversy exists regarding whether DHEA's effects on weight are mediated by changes in food intake or metabolic efficiency.

Purpose of the Study:

  • To review existing data on the effects of DHEA on food intake and obesity in rodent models.
  • To analyze the reasons for conflicting conclusions in previous studies.
  • To determine the relative contributions of metabolic and appetite effects of DHEA in weight management.

Main Methods:

  • Review and analysis of published studies investigating dehydroepiandrosterone (DHEA) effects on rodent obesity.
  • Comparison of results from studies with different experimental designs (short-term vs. long-term).
  • Evaluation of how normalization of food intake data for animal size influences study outcomes.

Main Results:

  • Conflicting conclusions in the literature stem from differences in experimental design; shorter studies highlight effects on food intake, while longer studies emphasize metabolic changes.
  • The method used to normalize food intake data for animal size can significantly influence analytical outcomes.
  • Dehydroepiandrosterone (DHEA) demonstrates both a direct metabolic effect and an impact on caloric consumption.

Conclusions:

  • Dehydroepiandrosterone (DHEA) influences obesity by affecting both metabolic processes and caloric intake.
  • Both metabolic alterations and reduced food consumption are crucial mechanisms through which DHEA modulates fat stores in obese animals.
