Discovery in zebrafish sheds light on nonalcoholic fatty liver disease A team of scientists from the University of Utah and the University of California at San Francisco has discovered that the mutation of a gene encoding a ketone body transporter triggers accumulation of fat and other lipids in the livers of zebrafish. This discovery, published in the Feb. 1, 2012, issue of Genes & Development, reveals that transport of ketone bodies out of the liver is a critical step in energy...

(Ivanhoe Newswire)-- Can brown fat make you thinner? A research team led by Andre Carpentier and Denis Richard at the Université de Sherbrook, in Quebec; attempted to find the answer. Brown adipose tissue also known as brown fat is a tissue known to burn calories and generate body heat in new born babies and rodents. Recently, adult humans were also found to have a small percentage of brown fat. The Canadian researchers were intrigued by the idea that if they could develop...

Study finds protein's entwined arm movements may control fate of potentially toxic payload Like a magician employing sleight of hand, the protein mitoNEET -- a mysterious but important player in diabetes, cancer and aging -- draws the eye with a flurry of movement in one location while the subtle, more crucial action takes place somewhere else. Using a combination of laboratory experiments and computer modeling, scientists from Rice University and the University of California, San Diego...

Limiting certain essential nutrients for several days before surgery–either protein or amino acids–may reduce the risk of serious surgical complications such as heart attack or stroke, according to a new Harvard School of Public Health (HSPH) study. The study appears in the January 25, 2012 issue of Science Translational Medicine. "Food restriction as a way to increase stress resistance may seem counterintuitive, but in fact our data indicate that the well-fed state is the...

Chemists have taken an important step in making artificial life forms from scratch. Using a novel chemical reaction, they have created self-assembling cell membranes, the structural envelopes that contain and support the reactions required for life. Neal Devaraj, assistant professor of chemistry at the University of California, San Diego, and Itay Budin, a graduate student at Harvard University, report their success in the Journal of the American Chemical Society. “One of our long...

The accumulation of α-synuclein, a small, negatively charged protein, in neural cells, is one of the hallmarks of Parkinson's disease. It has been suggested that oligomeric α-synuclein causes membranes to become permeable, or to form channels on the outer cell membrane. Now, a group of scientists from Sweden has found a way to reliably replicate α-synuclein aggregation on cell membranes to investigate how different forms of α-synuclein...

Why do we like fatty foods so much? We can blame our taste buds. Our tongues apparently recognize and have an affinity for fat, according to researchers at Washington University School of Medicine in St. Louis. They have found that variations in a gene can make people more or less sensitive to the taste of fat. The study is the first to identify a human receptor that can taste fat and suggests that some people may be more sensitive to the presence of fat in foods. The study is available...

Krill oil, derived from krill, is a small, shrimp-like crustacean found in cold water oceans, which are packed with omega-3 essential fatty acids and other key nutrients. Delray Beach, Fla., (PRWEB) January 10, 2012 Vitalmax Vitamins announced Monday that it has added an omega-3 krill oil supplement to its product line. Krill oil has gained widespread attention for its ability to deliver high amounts of omega-3, without many of the pitfalls associated with fish oil, such as the risk of...

Who knew that male fertility depends on sperm-cell architecture? A University of Illinois study reports that a certain omega-3 fatty acid is necessary to construct the arch that turns around, immature sperm cell into a pointy-headed super swimmer with an extra long tail. "Normal sperm cells contain an arc-like structure called the acrosome that is critical in fertilization because it houses, organizes, and concentrates a variety of enzymes that sperm use to penetrate an egg," said Manabu...
