Study finds little to no link between butter consumption and chronic disease or all-cause mortality

Butter consumption was only weakly associated with total mortality, not associated with cardiovascular disease, and slightly inversely associated (protective) with diabetes, according to a new epidemiological study which analyzed the association of butter consumption with chronic disease and all-cause mortality.

Using NMR to investigate intrinsically disordered proteins: an interview with Dr Isabella Felli

“IDPs” is now a widely used acronym that stands for “intrinsically disordered proteins.” It is the term generally used by the scientific community to refer to a wide variety of proteins that do not have a stable 3D structure and are instead characterized by a high extent of local mobility, disorder and many conformers that are accessible at room temperature.

Lab-established diagnosis necessary for treatment of patients with persistent diarrhea

Persistent diarrhea, which is diarrhea that lasts at least 14 days, is an illness typically caused by parasites or bacteria and requires accurate diagnosis in order to determine what treatment to give, according to Herbert L. DuPont, M.D., director of the Center for Infectious Diseases at The University of Texas Health Science Center at Houston School of Public Health.

Researchers investigate why N14Y, N14K mutations have distinct effects in KID syndrome patients

A team of New York-based researchers has compared the effects of two disease-causing mutations, potentially explaining why patients with the rare genetic disorder keratitis-ichthyosis-deafness (KID) syndrome can experience different sets of symptoms.

Blood levels of omega-3s fatty acids linked to lower risk of deadly heart attacks

Blood levels of seafood and plant-based omega-3 fatty acids are moderately associated with a lower risk of dying from heart attacks, according to a new epidemiological study, published today in JAMA Internal Medicine, led by Liana C. Del Gobbo, Ph.D., a postdoctoral research fellow in the division of cardiovascular medicine at Stanford University School of Medicine and senior author Dariush Mozaffarian, M.D., Dr.P.H., dean of the Friedman School of Nutrition Science and Policy at Tufts University in Boston.

Researchers find improvements in many aspects of U.S. diet

In nationally representative surveys conducted between 1999 and 2012, several improvements in self-reported dietary habits were identified, such as increased consumption of whole grains, with additional findings suggesting persistent or worsening disparities based on race/ethnicity and education and income level, according to a study appearing in the June 21 issue of JAMA.

New method helps analyse how cold viruses penetrate into cells

Cold viruses cause us irritation by penetrating into our cells and transporting their RNA into the cytoplasma of the infected cells. This is the only way they can multiply. The details of how the transfer of the RNA from within the virus occurs are difficult to study.

Regular exercise may help improve muscle repair response in older adults

Here's another reason why you should hit the gym regularly as you grow older: A new report appearing online in The FASEB Journal shows that regular exercise plays a critical role in helping muscles repair themselves as quickly as possible after injury.

Researchers uncover mechanism of two-in-one sensor protein KdpD

Uptake of potassium by bacteria is regulated by a single protein that senses the concentration of this cation both inside the cell and in the external medium, and controls the expression of the corresponding transport protein accordingly.

Drug candidate delivered by plant-virus-based carrier shows promise for triple-negative breast cancer

In a pair of firsts, researchers at Case Western Reserve University and Massachusetts Institute of Technology have shown that the drug candidate phenanthriplatin can be more effective than an approved drug in vivo, and that a plant-virus-based carrier successfully delivers a drug in vivo.

Scientists explore effects of physiological fluid shear on dangerous type of Salmonella

Once inside the human body, infectious microbes like Salmonella face a fluid situation. They live in a watery world, surrounded by liquid continually flowing over and abrading their cell surfaces--a property known as fluid shear.

Accumulation of fat droplets makes cancer cells more aggressive

It has been established that not all cancer cells are equally aggressive - most can be neutralised with radiation and chemotherapy. Researchers at Lund University in Sweden have now discovered that some cancer cells can accumulate fat droplets, which appear to make them more aggressive and increase their ability to spread.
