What is Metabolism?

Metabolic States of the Body: Fasting and Starvation

Metabolic States of the Body: Fasting and Starvation

During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...

Psychosurgery

Psychosurgery

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Area of Science:

Surgical Research
Obesity Treatment
Animal Models

Background:

Metabolic surgery offers significant potential for managing morbid obesity.
Development relies on both animal and clinical research.
This study details experimental animal options and surgical techniques.

Purpose of the Study:

To outline experimental animal options for metabolic surgery.
To describe technical surgical characteristics.
To detail specific animal care protocols.

Main Methods:

Review of key considerations in animal handling for surgical interventions.
Analysis of sleeve gastrectomy, Roux-en-Y gastric bypass, ileal transposition, and duodenal exclusion.

Main Results:

Technical variations exist, particularly in Roux-en-Y gastric bypass pouch capacity and intestinal anastomosis.
Ileal transposition results vary by animal model and show efficacy even in normal-weight animals.
Duodenal exclusion requires further study but may aid pre-operative weight loss.

Conclusions:

Discrepancies in experimental techniques necessitate further studies to confirm efficiency.
Metabolic surgery complements bariatric surgery, driving new research.
Careful selection of validated animal models is crucial for reliable metabolic surgery research.
