3-Hydroxyacyl CoA Dehydratase 2 Is Essential for Embryonic Development and Hepatic Metabolic Function Under a Low-Fat, High-Carbohydrate Diet

“…Following a 24 h acclimation period, we measured oxygen consumption (VO 2 ), carbon dioxide production (VCO 2 ), and respiratory exchange ratio (RER), with all values normalized to total body weight. We calculated substrate utilization and energy expenditure using established equations: Carbohydrate oxidation: (4.585 × VCO 2 − 3.226 × VO 2 ) × 4 (The multiplier 4 converts mass/time to kcal/time) [ 9 ]; similarly, Fat oxidation: (1.695 × VO 2 − 1.701 × VCO 2 ) × 9; Energy expenditure: (3.815 + 1.232 × RER) × VO 2 (Based on calorific value of oxygen) [ 10 ]. Physical activity was continuously monitored using infrared beam-break sensors.…”

In search of vigilance: The problem of iatrogenically created psychological phenomena.

“…Such strategies then require designs that are hedonomic in nature (Hancock, Pepe, & Murphy, 2005) such that individuals seek them out and actively wish to engage in the challenge they present. Alternatively, the task can be interpolated into or integrated directly with companion tasks that are more appealing (see Sweeley, Holland, Towson, & Chamberlain, 1987). Finally, it might be possible to hide the monitoring demand altogether, locating it behind an ongoing task.…”

“…Metabolic profiling was also extended to a new and novel detection system using musical sounds instead of graphs or tables to analyze normal and abnormal samples of urine. 91 ) Intensities at the apex of each GC peak were converted to frequencies and played on a digital keyboard, higher notes reflecting greater concentrations of metabolites. This was one of the first reports on the use of sound as a sense of perception in the field of analytical chemistry and became known whimsically in the press world-wide as “musical urines.”…”
