Lipids News and Research

RSS

Lipids are a broad group of naturally-occurring molecules which includes fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others. The main biological functions of lipids include energy storage, as structural components of cell membranes, and as important signaling molecules.

Scientists reveal the genetic determinants of fat storage in cells

New research by the Gladstone Institutes of Cardiovascular Disease (GICD) and the University of California, San Francisco (UCSF), has revealed the genetic determinants of fat storage in cells, which may lead to a new understanding of and potential treatments for obesity, diabetes, and heart disease. While scientists have long understood that lipid droplets contribute to fat build up in cells, the genes involved in droplet biology have been a focus of extensive research.

New blood test reveals risk for metabolic syndrome

University of Minnesota researchers have discovered that people with high oxidation levels of the low-density lipoprotein (LDL) particle that carries cholesterol throughout the blood are much more likely to develop metabolic syndrome - which can lead to a considerably increased risk of developing heart disease.

Radioactive carbon-14 determines the number of fat cells remains constant in all body types

The radioactive carbon-14 produced by above-ground nuclear testing in the 1950s and '60s has helped researchers determine that the number of fat cells in a human's body, whether lean or obese, is established during the teenage years. Changes in fat mass in adulthood can be attributed mainly to changes in fat cell volume, not an increase in the actual number of fat cells.

No link between aromatase inhibitors and cardiovascular problems

New evidence has emerged that, contrary to some current fears, aromatase inhibitors (AIs) are not associated with an increased risk of heart problems in women who take them to prevent their breast cancer recurring.

Potential drug target identified for diabetes by studying novel gut-brain-liver circuit

Scientists at the Toronto General Hospital Research Institute have discovered a novel signaling pathway between three organs - the gut, the brain, and the liver - which lowers blood sugar when activated.

Pistachios good for the heart

More good news for pistachio fans! According to new data unveiled this week at the Experimental Biology Conference in San Diego, snacking on pistachios has proved once again to have a positive impact on improving cardiovascular health by significantly reducing inflammation in the body, a prominent cardiovascular disease (CVD) risk factor.

Cholesterol in Parkinson's disease

In 2006, University of North Carolina at Chapel Hill researchers published a study that found people with low levels of LDL cholesterol are more likely to have Parkinson's disease than people with high LDL levels.

Pregnant mothers' diet linked to baby's obesity

Pregnant and lactating rats fed on a diet of hydrogenated fat during pregnancy and lactation had babies who were fatter than rats fed a normal diet, according to research published in Lipids in Health and Disease.

Monthly contact with counselor provides some benefit for maintaining weight loss

Weight-loss program participants who had a brief, monthly personal contact intervention - most often a 10-15 minute phone conversation - regained less weight than participants who were in a Web-based intervention or self-directed program, according to a study in the March 12 issue of JAMA, the Journal of the American Medical Association.
