Induced Pseudomembrane Enrichment in Long Nerve Allograft Reconstruction.

Introduction/aims: Long nerve defects are typically reconstructed with autograft or processed acellular nerve allograft (PNA). PNA is convenient and avoids donor morbidity but lacks the neurotrophic environment of autograft. Increased levels of neurotrophic factors have been identified in pseudomembranes induced around silicone implanted between nerve ends.

Resting metabolic rate, abdominal fat pad and liver metabolic gene expression in female rats provided a snacking diet from weaning to adulthood.

Our female rat model with continuous, ad libitum access to snacks and chow from weaning to adulthood closely mimics human feeding behavior from childhood onwards. It causes weight gain, enlarged abdominal fat pads, reduced insulin sensitivity and leptin resistance without an increase in total caloric intake. Our current study investigated if this change in energy partitioning is due to a decrease in resting metabolic rate (RMR).
