Ultrasound patch helps heal long standing venous skin ulceration of the legs. |
 |
 |
|
EurekAlert: In a small clinical study, researchers administered a new method for treating chronic wounds using a novel ultrasound applicator that can be worn like a band-aid. The applicator delivers low-frequency, low-intensity ultrasound directly to wounds, and was found to significantly accelerate healing in five patients with venous ulcers. Venous ulcers are caused when valves in the veins malfunction, causing blood to pool in the leg instead of returning to the heart. This pooling, called venous stasis, can cause proteins and cells in the vein to leak into the surrounding tissue leading to inflammation and formation of an ulcer.

Long-term use of calcium channel blockers linked to increased breast cancer risk. |
|
|
|
JAMA Internal Medicine: The study's key finding was that women currently taking calcium-channel blockers who have used them for 10 years or longer had an approximately two and a half times higher risk of both invasive ductal and invasive lobular cancers compared to those who never used such calcium-channel blockers and compared to users of other forms of antihypertensives. In contrast, the study found that use of other classes of antihypertensive drugs, including diuretics, beta blockers and angiotensin-receptor blockers, were not associated with an increased risk of breast cancer, even when used long term.

New approach to treat diseases with inherited mutations of mitochondrial DNA. |
|
|
|
EurekAlert: "Mitochondrial-targeted TALENS (mitoTALENs) represent the most promising hope for an effective treatment of diseases caused by mutations in mtDNA," said Carlos T. Moraes, Ph.D., a professor of neurology and cell biology at the University of Miami Miller School of Medicine and principal investigator of the study. "Our research demonstrates that mitoTALENs can substantially decrease or eliminate mutant mtDNA without harming normal mtDNA."

Eating a big breakfast: Pendulum swings back with new evidence claiming this is good. |
|
|
|
Tel Aviv University: So the time of day we eat can have a big impact on the way our bodies process food, says Prof. Daniela Jakubowicz of TAU's Sackler Faculty of Medicine and the Diabetes Unit at Wolfson Medical Center. In a recent study, she discovered that those who eat their largest daily meal at breakfast are far more likely to lose weight and waist line circumference than those who eat a large dinner.

Are we smarter than a 10-year old? Quantitative biology yields new insights into bacterial metabolism. |
|
|
|
UC San Diego: While quantitative biology papers are often filled with complicated mathematical formulas and involved heavy number crunching by computers, Hwa says the mathematics used in this discovery was surprisingly simple. “We just used line plots,” he says. “Our entire study involves just three linear equations. They’re the kind of things my 10-year-old daughter should be able to do. Quantitative biology doesn’t have to be fancy.” Like their mathematical approach, Hwa says his team’s experiments were simple enough most of them could have been done 50 years ago
