Enhanced NMR reveals chemical structures in a fraction of the time

EurekAlert! - Jue, 01/17/2019 - 23:00
MIT researchers have developed a way to dramatically enhance the sensitivity of nuclear magnetic resonance spectroscopy (NMR), a technique used to study the structure and composition of many kinds of molecules, including proteins linked to Alzheimer's and other diseases.

Smart microrobots that can adapt to their surroundings

EurekAlert! - Jue, 01/17/2019 - 23:00
Scientists at EPFL and ETH Zurich have developed tiny elastic robots that can change shape depending on their surroundings. Modeled after bacteria and fully biocompatible, these robots optimize their movements so as to get to hard-to-reach areas of the human body. They stand to revolutionize targeted drug delivery.

New study shows physician-targeted marketing is associated with increase in opioid overdose deaths

EurekAlert! - Jue, 01/17/2019 - 23:00
New research from NYU School of Medicine and Boston Medical Center published online Jan. 18 in JAMA Network Open shows that increased marketing of opioid products to physicians -- from consulting fees to free meals -- is associated with higher opioid prescribing rates and elevated overdose deaths in the US.

Improved maternity care practices decrease racial gaps in breastfeeding in the US South

EurekAlert! - Jue, 01/17/2019 - 23:00
A new paper published in Pediatrics links successful implementation of Baby-Friendly™ practices in the southern US with increases in breastfeeding rates and improved, evidence-based care. The changes were especially positive for African-American women.

Home-based hypertension program produces 'striking' results

EurekAlert! - Jue, 01/17/2019 - 23:00
Pilot study by Brigham investigators finds that an innovative care-delivery program helped 81 percent of participants achieve blood pressure control in seven weeks.

Have new appointment wait times improved at VA health care system?

EurekAlert! - Jue, 01/17/2019 - 23:00
This study compared new appointment wait times in the US Department of Veterans Affairs (VA) health care system with wait times in the private sector. Wait time data were for primary care, dermatology, cardiology or orthopedics at VA medical centers in 15 major metropolitan areas and private sector comparison data came from a published survey.

Is marketing of opioids to physicians associated with overdose deaths?

EurekAlert! - Jue, 01/17/2019 - 23:00
This study examined the association between pharmaceutical company marketing of opioids to physicians and subsequent death from prescription opioid overdoses across US counties. The study, which analyzed industry marketing information data and national data on opioid prescribing and overdose deaths, reports almost $40 million in opioid marketing was targeted to more than 67,500 physicians across more than 2,200 counties from August 2013 to December 2015.

Why do Hydra end up with just a single head?

EurekAlert! - Jue, 01/17/2019 - 23:00
Hydra is able to regenerate any part of its body to rebuild an entire individual. The head organizer performs two opposite activities, one activating, which causes the head to differentiate, and the other inhibiting, which prevents the formation of supernumerary heads. Researchers at UNIGE have discovered the identity of the inhibitor, called Sp5, and deciphered the dialogue between these two antagonistic activities, which helps maintain a single-headed adult body and organize an appropriate regenerative response.

No substantial benefit from transplantation reported for a high-risk leukemia subtype

EurekAlert! - Jue, 01/17/2019 - 23:00
Study led by St. Jude Children's Research Hospital found treatment guided by measuring minimal residual disease was associated with better outcomes for hypodiploid acute lymphoblastic leukemia patients.

Classic double-slit experiment in a new light

EurekAlert! - Jue, 01/17/2019 - 23:00
An international research group has developed a new X-ray spectroscopy method based on the classical double-slit experiment to gain new insights into the physical properties of solids.

Gene therapy promotes nerve regeneration

EurekAlert! - Jue, 01/17/2019 - 23:00
Researchers from the Netherlands Institute for Neuroscience and the Leiden University Medical Center have shown that treatment using gene therapy leads to a faster recovery after nerve damage. By combining a surgical repair procedure with gene therapy, the survival of nerve cells and regeneration of nerve fibers over a long distance was stimulated. The discovery, published in Brain, is an important step towards the development of a new treatment for people with nerve damage.
