Meet Brown Fat By Mary RD on Apr 23 2009 160 12 00 PM in Dieting

Meet Brown Fat By Mary RD on Apr 23 2009 160 12 00 PM in Dieting mp You Brown fat is a major calorie burner It might be the reason why some people eat and stay slim while others eat and get fat Brown fat was in the news last week nbsp You know you rsquo re a nutrition wonk if you honk for brown fat How now brown fatA quick lesson about fat in the body not the fat in food you eat nbsp there are two kinds of fat tissue white fat and brown fat nbsp The more familiar white fat stores potential energy nbsp White fat is ultimately broken down to ATP stay with me the form of energy used by the body nbsp Brown fat on the other hand provides immediate energy by burning calories to generate heat nbsp You rsquo ve heard of solar energy wind energy and energy from fossil fuels nbsp Brown fat is direct energy too nbsp Brown fat is 8220 brown 8221 because it contains iron rich enzymes that are lacking in white fat Brrr Brown fat cells become active and grow when exposed to the cold nbsp For instance hibernating animals grow and burn brown fat for heat during the winter Newborn humans also make brown fat to protect against the cold nbsp Infants don 8217 t shiver because their brown fat keeps them warm nbsp Brown fat was thought to disappear after infancy but last week three groups of scientists published research showing that humans can generate brown fat all life long The scientists stimulated brown fat production by keeping their research subjects very cold Two groups stuck their subjects in extra chilly rooms and one group submerged the subjects 8217 tootsies in an ice water bath nbsp After a few hours the research subjects produced significant amounts of brown fat nbsp It showed up as bursts of light in the neck and upper back when imaged by a PET Positron Emission Tomography scan Sure enough as for hibernating animals brown fat is there to warm humans in extreme cold What if hellip An absence of brown fat predisposes a person to obesity nbsp Obese people might h

Positron Emission Tomography PET was much more sensitive and

Positron Emission Tomography PET was much more sensitive and more accurate than conventional imaging methods in detecting response to treatment in sarcoma patients according to a UCLA study led by Dr Fritz Eilber that is among the first to directly compare PET to CT scanning The study has important implications for patients If conventional imaging fails to detect treatment response oncologists may discontinue therapies that in fact are working and study participants may be dismissed from clinical trials that are actually helping them Conversely if a patient is not responding using PET scanning to evaluate response could help prevent them from undergoing toxic therapies that aren t working

Pre PET Headgear Positron Emission Tomography

In 1961 chemists at Brookhaven National Laboratory studied how to detect small brain tumors by analyzing the decay of radioactive material injected into the patient s bloodstream and preferentially absorbed by the tumor To help them BNL s Instrumentation Division built different arrays of detectors and this circular type proved best In the 1970 s BNL helped reconstruct the raw data received by the detectors into an image of the working brain This breakthrough led to more practical devices for imaging areas of the brain today s PET machines Today Brookhaven is a leader in addiction research Today BNL uses PET technology to study major areas of medical research including drug and alcohol addiction the development of a new strategy for addiction treatment obesity and eating disorders attention deficit hyperactivity disorder ADHD aging and neurodegenerative disorders
