Fighting obesity with thermal imaging

2012-07-19
(Press-News.org) Scientists at The University of Nottingham believe they've found a way of fighting obesity — with a pioneering technique which uses thermal imaging. This heat-seeking technology is being used to trace our reserves of brown fat — the body's 'good fat' — which plays a key role in how quickly our body can burn calories as energy.

This special tissue known as Brown Adipose Tissue, or brown fat, produces 300 times more heat than any other tissue in the body. Potentially the more brown fat we have the less likely we are to lay down excess energy or food as white fat.

Michael Symonds, Professor of Developmental Physiology in the School of Clinical Sciences, led a team of scientists and doctors at The University of Nottingham who have pioneered the thermal imaging process so we can assess how much brown fat we've got and how much heat it is producing. Their research has just been published in the Journal of Pediatrics.

The University of Nottingham's Early Life Nutrition Research Unit is at the forefront of ground-breaking international research into managing brown adipose tissue using nutrition, exercise, and environmental and therapeutic interventions.

Thermogenic index for food labels

Professor Symonds said: "Potentially the more brown fat you have or the more active your brown fat is you produce more heat and as a result you might be less likely to lay down excess energy or food as white fat.

"This completely non-invasive technique could play a crucial role in our fight against obesity. Potentially we could add a thermogenic index to food labels to show whether that product would increase or decrease heat production within brown fat. In other words whether it would speed up or slow down the amount of calories we burn."

The obesity threat

Obesity is one of the biggest challenges we face in Europe and America as our children grow older. It affects 155 million children worldwide. In the UK the number of overweight children doubled in the 1990s.

Dr Helen Budge, Clinical Associate Professor and Reader in Neonatology, said: "Babies have a larger amount of brown fat which they use up to keep warm soon after birth making our study's finding that this healthy fat can also generate heat in childhood and adolescence very exciting."

Professor Symonds and his team say their ground-breaking research could lead to a better understanding of how brown fat balances the energy from the food we eat with the energy our bodies actually use up.

Professor Symonds, together with Dr Budge and their team from the University's School of Clinical Sciences has shown that the neck region in healthy children produces heat. With the help of local school children they found that this region, which is known to contain brown adipose tissue, rapidly switches on to produce heat. This capacity is much greater in young children compared with adolescents and adults. The researchers are now using their findings to explore interventions designed to promote energy use as heat and, thus, prevent excess weight gain in both children and adults.

Non-invasive technology

Professor Symonds said: "Using our imaging technique we can locate brown fat and assess its capacity to produce heat. It avoids harmful techniques which use radiation and enables detailed studies with larger groups of people. This may provide new insights into the role of brown fat in how we balance energy from the food we eat, with the energy our bodies use up.

UCF discovers exoplanet neighbor smaller than Earth

2012-07-19
The University of Central Florida has detected what could be its first planet, only two-thirds the size of Earth and located right around the corner, cosmically speaking, at a mere 33light- years away. The exoplanet candidate called UCF 1.01, is close to its star, so close it goes around the star in 1.4 days. The planet's surface likely reaches temperatures of more than 1,000 degrees Fahrenheit. The discoverers believe that it has no atmosphere, is only two-thirds the gravity of Earth and that its surface may be volcanic or molten. "We have found strong evidence for ...

El Zotz masks yield insights into Maya beliefs

2012-07-19
PROVIDENCE, R.I. [Brown University] — A team of archaeologists led by Brown University's Stephen Houston has uncovered a pyramid, part of the Maya archaeological site at El Zotz, Guatemala. The ornately decorated structure is topped by a temple covered in a series of masks depicting different phases of the sun, as well as deeply modeled and vibrantly painted stucco throughout. The team began uncovering the temple, called the Temple of the Night Sun, in 2009. Dating to about 350 to 400 A.D., the temple sits just behind the previously discovered royal tomb, atop the Diablo ...

Parental consent for HPV vaccine should not be waived, poll says

2012-07-19
ANN ARBOR, Mich. – Most U.S. adults support laws that allow teens to get medical care for sexually transmitted infections without parental consent. But when asked about the vaccine against the human papillomavirus (HPV), most adults want parents to have the final say on whether their teen or pre-teen gets the shots. The University of Michigan C.S. Mott Children's Hospital National Poll on Children's Health recently asked a national sample of adults about allowing adolescents age 12 to 17 years old to receive the HPV vaccinations without parental consent. Only 45 percent ...

Scientists develop new carbon accounting method to reduce farmers' use of nitrogen fertilizer

2012-07-19
It's summer. For many of us, summer is a time synonymous with fresh corn, one of the major field crops produced in the United States. In 2011, corn was planted on more than 92 million acres in the U.S., helping the nation continue its trend as the world's largest exporter of the crop. Corn is a nitrogen-loving plant. To achieve desired production levels, most U.S. farmers apply synthetic nitrogen fertilizer to their fields every year. Once nitrogen fertilizer hits the ground, however, it's hard to contain and is easily lost to groundwater, rivers, oceans and the atmosphere. "That's ...

Sleep deprivation may reduce risk of PTSD according to Ben-Gurion U. researchers

2012-07-19
BEER-SHEVA, Israel, July 17, 2012 –Sleep deprivation in the first few hours after exposure to a significantly stressful threat actually reduces the risk of Post-Traumatic Stress Disorder (PTSD), according to a study by researchers from Ben-Gurion University of the Negev (BGU) and Tel Aviv University. The new study was published in the international scientific journal, Neuropsychopharmacology. It revealed in a series of experiments that sleep deprivation of approximately six hours immediately after exposure to a traumatic event reduces the development of post trauma-like ...

Protein build-up leads to neurons misfiring

2012-07-19
Using a two-photon microscope capable of peering deep within living tissue, researchers at the University of California, San Diego School of Medicine have found new evidence that alpha-synuclein protein build-up inside neurons causes them to not only become "leaky," but also to misfire due to calcium fluxes. The findings – the first recorded in vivo using a transgenic mouse model of Parkinson's disease – are published in the July 18 issue of The Journal of Neuroscience and provide new insights into how Parkinson's disease and other neurodegenerative disorders known as ...

Leaf litter and soil protect acorns from prescribed fire

2012-07-19
U.S. Forest Service scientists have found that prescribed fires with the heat insulation of leaf litter and soil can help restore oak ecosystems. Forest Service researchers are helping land managers find the best time to use prescribed fire when oak regeneration from acorns is a concern. "Acorns inside the leaf litter or in the soil are for the most part protected from fire," says Cathryn Greenberg, Forest Service Southern Research Station (SRS) researcher and lead author of the study published in July in the journal Forest Ecology and Management. "However, when acorns ...

Environmental concerns increasing infectious disease in amphibians, other animals

2012-07-19
CORVALLIS, Ore. – Climate change, habitat destruction, pollution and invasive species are all involved in the global crisis of amphibian declines and extinctions, researchers suggest in a new analysis, but increasingly these forces are causing actual mortality in the form of infectious disease. Amphibians are now, and always have been hosts for a wide range of infectious organisms, including viruses, bacteria and fungi, scientists said in a review published in Philosophical Transactions of the Royal Society B. But in recent decades, disease seems to have taken a more ...

A stronger doctor-patient relationship for the costliest patients

2012-07-19
Patients who are frequently hospitalized account for a disproportionate amount of health care spending in the United States. Working with a $6.1 million grant, a new University of Chicago Medicine program will test whether an updated version of the traditional general practitioner can reduce spending while also improving care for these patients. Under the new model, funded by a Health Care Innovation Award from the Center for Medicare & Medicaid Innovation, multidisciplinary teams led by a comprehensive care physician (CCP) will care for patients in both outpatient and ...

Green plants reduce city street pollution up to 8 times more than previously believed

2012-07-19
Trees, bushes and other greenery growing in the concrete-and-glass canyons of cities can reduce levels of two of the most worrisome air pollutants by eight times more than previously believed, a new study has found. A report on the research appears in the ACS journal Environmental Science & Technology. Thomas Pugh and colleagues explain that concentrations of nitrogen dioxide (NO2) and microscopic particulate matter (PM) — both of which can be harmful to human health — exceed safe levels on the streets of many cities. Past research suggested that trees and other green ...
