Lipids News and Research RSS Feed - Lipids News and Research

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.
Understanding how individuals respond to aspirin

Understanding how individuals respond to aspirin

Researchers have learned new information about how different people respond to aspirin, a globally prescribed drug in cardioprotection. The research team, led by scientists at Cardiff University in the United Kingdom and including representatives from the University of Alabama at Birmingham and the University of Colorado, identified more than 5,600 lipids — or fats — in blood platelets and gained new insights into how these cells respond to aspirin.

Scientists derive first molecular model of critical transporter at blood-brain barrier

Scientists derive first molecular model of critical transporter at blood-brain barrier

Scientists from Duke-NUS Medical School have derived a structural model of a transporter at the blood-brain barrier called Mfsd2a. This is the first molecular model of this critical transporter, and could prove important for the development of therapeutic agents that need to be delivered to the brain --- across the blood-brain barrier. In future, this could help treat neurological disorders such as glioblastoma. [More]
Caltech researchers map out pathways of neurons responsible for Parkinson's motor impairments

Caltech researchers map out pathways of neurons responsible for Parkinson's motor impairments

Because billions of neurons are packed into our brain, the neuronal circuits that are responsible for controlling our behaviors are by necessity highly intermingled. This tangled web makes it complicated for scientists to determine exactly which circuits do what. Now, using two laboratory techniques pioneered in part at Caltech, Caltech researchers have mapped out the pathways of a set of neurons responsible for the kinds of motor impairments--such as difficulty walking--found in patients with Parkinson's disease.

Using proteomics to understand Alzheimer’s: an interview with Dr Renã Robinson

Using proteomics to understand Alzheimer’s: an interview with Dr Renã Robinson

In our bioanalytical mass spectrometry lab we use proteomics techniques to try to understand more about Alzheimer's disease. The primary thrust of our research is that we're interested in understanding the changes that take place outside of the brain and how those correlate with what's taking place inside the brain [More]

New refractive index detector with a very wide dynamic range from KNAUER

At Analytica 2016, the trade show for the laboratory field taking place in Munich from May 10th to 13th, KNAUER will be introducing a newly developed refractive index (RI) detector with most up-to-date features. [More]
Specific intake levels of xanthohumol reduces obesity, cholesterol and elevated glucose

Specific intake levels of xanthohumol reduces obesity, cholesterol and elevated glucose

A recent study at Oregon State University has identified specific intake levels of xanthohumol, a natural flavonoid found in hops, that significantly improved some of the underlying markers of metabolic syndrome in laboratory animals and also reduced weight gain. [More]

Kidney possesses circadian clock that regulates, coordinates variety of organ's functions

An internal clock within the kidneys plays an important role in maintaining balance within the body, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology. [More]
Study finds how tumour cells grow through scavenging bad cholesterol

Study finds how tumour cells grow through scavenging bad cholesterol

Several studies have recognized a link between obesity and cancer. Richard Lehner, professor of Pediatrics and investigator at the University of Alberta's Faculty of Medicine & Dentistry, has taken his research further to understand how tumour cells grow through scavenging very low-density lipoproteins (VLDL) and low-density lipoproteins (LDL), commonly known as the "bad cholesterol", and what mechanisms can be used to reduce the malignant cells' growth.

Blocking of LIPG activity could arrest breast cancer growth

Blocking of LIPG activity could arrest breast cancer growth

In an article published in Nature Communications, the researchers report that breast cancer cells need to take up lipids from the extracellular environment in order to continue proliferating. [More]
Adding liraglutide to diet and exercise plan may help people lose weight, reduce diabetes risk

Adding liraglutide to diet and exercise plan may help people lose weight, reduce diabetes risk

For people with prediabetes who are overweight or obese, adding 3.0 mg of liraglutide for three years to a diet and exercise plan may lead to major health improvements, new industry-sponsored research suggests. The results will be presented Monday, April 4, at ENDO 2016, the annual meeting of the Endocrine Society, in Boston. [More]
Daily walnut consumption positively impacts blood cholesterol levels in older adults

Daily walnut consumption positively impacts blood cholesterol levels in older adults

Initial findings from the Walnuts and Healthy Aging study presented at Experimental Biology 2016 (EB) indicate that daily walnut consumption positively impacts blood cholesterol levels without adverse effects on body weight among older adults. [More]

Study reveals how lipids control SH2 domain-mediated cellular protein interactions

Prof. You-Me Kim and her student Dajung Jung at Pohang University of Science and Technology, in collaboration with Prof. Wonhwa Cho's group at the University of Illinois at Chicago, have identified that the majority of human Src homology 2 (SH2) domains not only bind to proteins, but also interact with membrane lipids with high affinity and specificity.

Scientists identify two enzymes that appear to play role in metabolism, inflammation

A team led by scientists at The Scripps Research Institute and the Salk Institute for Biological Studies has discovered two enzymes that appear to play a role in metabolism and inflammation—and might someday be targeted with drugs to treat type 2 diabetes and inflammatory disorders. [More]

Stanford researchers develop machine for designing better contact lenses

When contact lenses work really well, you forget they are on your eyes. You might not feel the same at the end of a long day staring at a computer screen. After too many hours of wear, the lenses and your eyes dry out, causing irritation that might outweigh the convenience of contacts. [More]

Inhibiting cholesterol esterification can potentiate antitumor activity of killer T cells

Inhibiting cholesterol esterification can potentiate antitumor activity of killer T cells

As key players in the immune system, T cells provide tumor surveillance and have direct antitumor effects. However, tumors can escape T-cell attack through various mechanisms in the tumor microenvironment. Reactivating the antitumor effects of T cells has shown great clinical benefits in treating various cancers. [More]
