Scientists think that what they learn by studying mouse brown fat might not be applicable to people because mouse and human brown fat are at different locations. "Taken together, our studies reveal a mouse BAT depot that represents human BAT and provides a unique tool for developing new translatable approaches for utilizing human scBAT." In addition, mouse brown fat in the collar bone is morphologically similar to human brown fat in the same location, produces compounds involved in the production of heat, and expresses genes similar to those expressed by human brown fat." In mice, brown fat activated to produce heat markedly affects the energy balance. In people, however, the main depots of brown fat are located above the collar bones and deep in the neck.
Obesity Surgery May Work by Remaking Your Gut Microbiome
The results confirmed earlier research with a smaller sample size, and also compared gastric bypass with another popular, though less invasive bariatric surgery. And like other members of the Bacillus family, it's associated with weight loss. When researchers transplanted beneficial microbes from mice that had undergone gastric bypass surgery into obese mice with normal-sized stomachs, they saw the same kind of dramatic weight loss caused by the surgery itself. It turns out gastric bypass not only restructures the topology of the human gut, but profoundly changes which microbes can survive and thrive in it. Bariatric surgery comes in a few flavors; there are stomach staples and industrial strength rubber bands.collected by :Lucy William
