Researchers make white fat take on characteristics of brown fat

Brown seems to be the color of choice when it comes to the types of fat cells in our bodies. Brown fat expends energy, while its counterpart, white fat stores it. The danger in white fat cells, along with the increased risk for diabetes and heart disease it poses, seems especially linked to visceral fat. Visceral fat is the build-up of fat around the organs in the belly.

Researchers identify new mechanism that causes choroidal neovascularization

Sloppy shipping of a donated human retina to an Indiana University researcher studying a leading cause of vision loss has inadvertently helped uncover a previously undetected mechanism causing the disease. The discovery has led researchers to urge review of how millions of dollars are spent investigating the cause of a type of age-related macular degeneration called choroidal neovascularization.

PDE4 enzyme regulates division of tumour cells and blood vessel growth in cancer tissue

Lung cancer is the leading cause of cancer death throughout the world. Standard treatment methods do not usually result in long-term recovery. In addition to the proliferation of the tumour cells, the growth of blood vessels controls tumors development. The blood vessel growth is controlled by several signalling molecules. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim and Justus Liebig University Giessen have discovered a molecule that plays a key role in this process. They succeeded in reducing tumour growth in their experiments by blocking the phosphodiesterase PDE4.

TCFC completes two in-utero fetal cardiac interventions to treat HLHS

The team at Texas Children's Fetal Center, a national leader for treating fetal anomalies, has successfully completed two in-utero fetal cardiac interventions to treat hypoplastic left heart syndrome (HLHS), a congenital heart defect that is one of the most complex heart defects to treat.

Improved lung-cancer screening by combining blood test with CT imaging

National Jewish Health is seeking to refine and improve lung-cancer screening by combining a blood test with CT imaging to detect disease earlier and more effectively. The trial combines a CT chest scan and the EarlyCDT-Lung blood test to screen for cancer, and seeks to build on recent research demonstrating that CT screening alone can reduce lung-cancer mortality.

Jogging may add years to life: Study

According to a new study from Denmark, jogging regularly may help a person live longer. The findings show that women who regularly jogged lived 5.6 years longer than women who didn't, and men who jogged lived 6.2 years longer than those who didn't.

U of A engineers develop wireless health-monitoring system

An interdisciplinary team of engineers at the University of Arkansas has developed a wireless health-monitoring system that gathers critical patient information, regardless of the patient's location, and communicates that information in real time to a physician, hospital or the patient herself.

Regular jogging increases life expectancy

Undertaking regular jogging increases the life expectancy of men by 6.2 years and women by 5.6 years, reveals the latest data from the Copenhagen City Heart study presented at the EuroPRevent2012 meeting.

Hypoxia may be a primary cause of uncontrollable tumor growth in cancers

Low oxygen levels in cells may be a primary cause of uncontrollable tumor growth in some cancers, according to a new University of Georgia study. The authors' findings run counter to widely accepted beliefs that genetic mutations are responsible for cancer growth.

Scientists determine structure of green pigment seen in nitrite-cured bacon, other meats

As with many concerned consumers, a team of University of Oklahoma researchers wondered if the green color sometimes seen in bacon is, in fact, harmful to human health. Recently, these OU scientists took an important first step in answering this question by determining the structure of the green pigment responsible for this 'nitrite burn.'

Gas NO plays a fundamental regulatory role in controlling bacterial function

Bacteria provide a well-known playground for scientists and the evolution of these earliest life forms has shed important perspective on potential therapies for some of the most common, deadly diseases. Researchers at Case Western Reserve University School of Medicine have now discovered that, the gas nitric oxide (NO), produced in all cells of the human body for natural purposes, plays a fundamental regulatory role in controlling bacterial function, via a signaling mechanism called S-nitrosylation (SNO), which binds NO to protein molecules.

Handheld plasma-producing device can instantly kill bacteria

A group of Chinese and Australian scientists, including CSIRO, have developed a handheld, battery-powered plasma-producing device that can rid skin of bacteria in an instant. The handheld plasma flashlight could be used in ambulance emergency calls, natural disaster sites, military combat operations and many other instances where treatment is required in remote locations.

One organ donor can save up to eight lives

Judy Weimer, 53, was diagnosed with COPD, emphysema and bronchitis on New Year's Eve in 2005 and received a double-lung transplant in 2009 at Loyola University Health System. "I named my new lungs Lucy and Ethel to welcome them," said the humorous and outgoing Chicagoan. "Lucy acts up once in a while but they are both working fine."

Helpful roles of rank, toxic substances

Usually, we think of mold, feces, nitric oxide, hydrogen sulfide and rat poison as rank, toxic or both. But scientists funded by the National Institutes of Health are learning more about the helpful roles these substances can play.

Custom-made mouthpieces can decrease levels of serum cortisol following exercise

Mouthguards are used by almost everyone participating in sports. These devices, typically purchased over-the-counter and used on the upper teeth, are designed to protect against broken teeth and an injured tongue. Recently, researchers in South Carolina found that a customized device which rests on the lower jaw can decrease levels of serum cortisol following exercise.
