abstract：:Brown adipose tissue (BAT) is present throughout life in rodents and plays an important role in energy balance. However, whereas BAT is clearly recognizable in the neonates of larger mammals (including dogs, cats, sheep, cattle, and humans), it is undetectable or present in only small quantities in adults of these spe...
