UCSF Identifies New Target Against Obesity Involving Brown Fat In the war against obesity, one´s own fat cells may seem an unlikely ally, but new research from the University of California, San Francisco (UCSF) suggests ordinary fat cells can be reengineered to burn calories. While investigating how a common drug given to people with diabetes works in mice, a UCSF team discovered that a protein called PRDM16, found in both men and mice, can throw a switch on fat cells, converting...

A chemically altered osteoporosis drug may be useful in fighting malaria, researchers report in a new study. Unlike similar compounds tested against other parasitic protozoa, the drug readily crosses into the red blood cells of malaria-infected mice and kills the malaria parasite. The drug works at very low concentrations with no observed toxicity to the mouse. The researchers found the drug by screening a library of about 1,000 compounds used in previous efforts to target an important...

A diet lacking in omega-3 fatty acids, nutrients commonly found in fish, may cause your brain to age faster and lose some of its memory and thinking abilities, according to a study published in the February 28, 2012, print issue of Neurology®, the medical journal of the American Academy of Neurology. Omega-3 fatty acids include the nutrients called docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). "People with lower blood levels of omega-3 fatty acids had lower brain volumes...

Defects in a protein that functions as a dietary fat sensor may be a cause of obesity and liver disease, according to a study published in the journal Nature, led by researchers at Imperial College London. The findings highlight a promising target for new drugs to treat obesity and metabolic disorders. The protein GPR120 is found on the surface of cells in the gut, liver and fat tissue and allows cells to detect and respond to unsaturated fatty acids from the diet, especially the omega-3...

Lipids help control the development of cell polarity In a standard biology textbook, cells tend to look more or less the same from all sides. But in real life cells have fronts and backs, tops and bottoms, and they orient many of their structures according to this polarity explaining, for example, why yeast cells bud at one end and not the other. Over the last few years, Rong Li, Ph.D., and her team at the Stowers Institute for Medical Research have figured out many important details of...

In “Mass Extinctions: Nature´s Spectacular Staging of Natural Selection” Julian Lieb, M.D  provides evidence that “die-offs” or mass deaths are episodes of natural selection, caused by activation of enzymes of the arachidonic acid cascade. In prior publications, Dr Lieb showed that products of the arachidonic acid cascade are the agents of natural selection and evolution, differentiating between infertility and reproduction, and between health and...

Fish oil is known to lower triglycerides, but can it prevent a heart attack? Doctors from Baylor College of Medicine involved in a multi-institutional study are testing a highly purified form of fish oil to see if it can reduce the risk of heart attack for those who are also on a statin, a cholesterol-reducing drug. Triglycerides and cholesterol are different types of lipids, or fat, found in the blood stream. The body needs these lipids to function properly, but too much can raise the...

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...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
