Estimating Body Composition of Lizards from Total Body Electrical Conductivity and Total Body Water
Nondestructive methods of estimating body composition are crucial for measuring energy budgets of free-ranging animals. However, most methods have proved to be either difficult or inaccurate for estimating lipid mass, particularly in small animals. I validated the use of total body electrical conductivity (TOBEC) and total body water (TBW) to estimate lean mass and nonpolar lipid mass in the li...

متن کاملComparison of Muscle Mass, Total Body Water and Total Body Protein in Type II Diabetics with Healthy Matched Adults by Bioelectrical Impedance Analysis
Background: Bioelectrical impedance analysis (BIA) is a new and rapid technique to validate body composition. Several studies have used this technique to evaluate body compositions, such as muscle mass, in diabetic patients, but the results are very different. This may due the differences between diabetic patients and control group. Therefore, this study aimed to compare the muscle mass of diab...
متن کاملTotal Body Electrical Conductivity (tobec) to Estimate Total Body Fat of Free-living Birds
Traditional methods to determine total body fat are undesirable under many circumstances because they require sacrificing individual birds. Walsberg (1988) recently introduced the total body electrical conductivity (TOBEC) method for total body fat to ecological studies. In this paper we expand on Walsberg’s (1988) seminal paper and show that: (1) TOBEC is accurate under a narrow array of body ...
متن کاملTotal body water and total body potassium in patients with continent ileostomies.
Total body water and total body potassium were studied in 14 patients submitted to proctocolectomy six to 10 years after they had been provided with a continent ileostomy. Total body water was determined with an isotope dilution technique using tritiated water as a tracer. Total body potassium was determined by counting the gamma radiation from the naturally present nuclid 40K in a total body c...
