Case study reveals therapy to reduce sarcoidosis symptoms in 5q-myelodysplastic syndrome

Glenview, Ill. (August 4, 2015) -- A case study published in the August issue of the journal CHEST found lenalidomide treatments may have an immediate effect in the treatment of sarcoidosis-related symptoms. Sarcoidosis, a disease that involves abnormal collections of inflammatory cells that can form nodules in various organs, can affect individuals from all racial and age groups. To date, no optimal therapies have been effective in managing this condition. This finding was reported in the case of a 71-year-old woman with a long-standing history of refractory pulmonary ...

Projected benefits of high BP treatment in China

An expanded program of treatment for hypertension could prevent about 800,000 cardiovascular disease (CVD) events every year in China, according to a modeling study published this week in PLOS Medicine. The predictions of this simulation, reported by Andrew Moran of Columbia University and colleagues, indicate that such a program should also be borderline cost-effective, provided low cost essential anti-hypertensive drugs are used. Hypertension is the leading cardiovascular risk factor in China, the world's most populous country. About 325 million adults in China have ...

How to trust what your customers say about your brand

UNIVERSITY OF CALIFORNIA, BERKELEY'S HAAS SCHOOL OF BUSINESS- Marketers would love to get inside the consumer brain. And now they can. Researchers at UC Berkeley's Haas School of Business are using functional magnetic resonance imaging (fMRI) to see if what people say about brands matches what they are actually thinking. In their paper, "From 'Where' to 'What': Distributed Representations of Brand Associations in the Human Brain (Journal of Marketing Research: August 2015, Vol. 52, No. 4), co-authors Ming Hsu and Leif Nelson, Berkeley-Haas marketing professors, and Yu-Ping ...

Keeping algae from stressing out

While most people might know some algae as "pond scum," to the U.S. Department of Energy (DOE), they are tiny organisms that could provide a source of sustainable fuels. Like plants, they can convert light into energy-rich chemical compounds; unlike plants, they require less space and don't need arable soil to grow. Some algae like Chlamydomonas reinhardtii (or "Chlamy," as it's known to its large research community) produce energy-dense oils or lipids when stressed, and these lipids can then be converted into fuels. However, researchers walk a fine line in not killing ...

Giving robots a more nimble grasp

Most robots on a factory floor are fairly ham-handed: Equipped with large pincers or claws, they are designed to perform simple maneuvers, such as grabbing an object, and placing it somewhere else in an assembly line. More complex movements, such as adjusting the grasp on an object, are still out of reach for many industrial robots. Engineers at MIT have now hit upon a way to impart more dexterity to simple robotic grippers: using the environment as a helping hand. The team, led by Alberto Rodriguez, an assistant professor of mechanical engineering, and graduate student ...

Parents' preconception exposure to environmental stressors can disrupt early development

Washington, DC-Even before a child is conceived, the parents' exposure to environmental stressors can alter the way genes are expressed and ultimately harm the child's health when those genes are passed down to the next generation, according to a new article published in the Endocrine Society's journal Endocrinology. Exposure to environmental stressors such as endocrine-disrupting chemicals, psychological stress and malnutrition may result in disadvantageous epigenetic "reprogramming" that can echo through multiple generations. When these stressors disrupt early developmental ...

Dental coverage for patients with Medicaid may not prevent tooth-related ER visits

More than 2 percent of all emergency department visits are now related to nontraumatic dental conditions, according to a study by researchers at Stanford University, the University of California-San Francisco, Truven Health Analytics and the federal Agency for Healthcare Research and Quality. Although the expansion of Medicaid under the Affordable Care Act has made millions of low-income and rural Americans eligible for health insurance, many states don't provide dental coverage for adults under their Medicaid programs. Paying for dental insurance on the individual market ...

Can habitat protection save our disappearing bats?

This news release is available in French. In summertime, bats are a common feature in the night sky, swooping around backyards to gobble up mosquitos. Bats also help with crops: they act as a natural pesticide by feeding on harmful insects. But these winged mammals are now under threat. As agricultural intensification expands across the world, the conversion of their natural habitats has caused a dramatic decline in population. North American bats are also plagued with white-nose syndrome, an emerging infectious disease that's decimating their numbers. "Many bat ...

Opioid use and sexual violence among drug-using young adults in NYC

The nonmedical use of prescription opioids (POs) has become an area of increasing public health concern in the United States and rates of use are particularly high among young adults. In the past decade, an emerging "epidemic" of nonmedical PO use has been reported. Among young adults, self-reported use is 11% and overdose deaths involving POs now exceed deaths involving heroin and cocaine combined. Sexual violence is also a serious problem in the United States receiving increased national attention, and the relationship between substance use and sexual violence is well ...

Precariously balanced rocks provide clues for unearthing underground fault connections

Irvine, Calif., Aug. 4, 2015 - Stacked in gravity-defying arrangements in the western San Bernardino Mountains, near the San Andreas Fault, granite boulders that should have been toppled by earthquakes long ago resolutely remain. In exploring why these rocks still stand, researchers have uncovered connections between Southern California's San Jacinto and San Andreas faults that could change how the region plans for future earthquakes.

Eating away at cognitive decline

While cognitive abilities naturally diminish as part of the normal aging process, it may be possible to take a bite out of this expected decline. Eating a group of specific foods known as the MIND diet may slow cognitive decline among aging adults, even when the person is not at risk of developing Alzheimer's disease, according to researchers at Rush University Medical Center. This finding is in addition to a previous study by the research team that found that the MIND diet may reduce a person's risk in developing Alzheimer's disease. The recent study shows that older ...

Cures for PTSD often remain elusive for war veterans

Our nation's veterans continue to suffer emotional and psychological effects of war--some for decades. And while there has been greater attention directed recently toward post-traumatic stress disorder (PTSD), and more veterans are seeking help, current psychotherapy treatments are less than optimal, according to a new narrative review published in the August 4, 2015 issue of JAMA. In a review of medical literature over a 35-year period, researchers from the Steven and Alexandra Cohen Center for Post-Traumatic Stress and Traumatic Brain Injury -- a program in the Department ...

Scientists solve mystery behind earthworm digestion

Scientists have discovered how earthworms can digest plant material, such as fallen leaves, that would defeat most other herbivores. Earthworms are responsible for returning the carbon locked inside dead plant material back into the ground. They drag fallen leaves and other plant material down from the surface and eat them, enriching the soil, and they do this in spite of toxic chemicals produced by plants to deter herbivores. The scientists, led by Dr Jake Bundy and Dr Manuel Liebeke from Imperial College London, have identified molecules in the earthworm gut that ...

New device converts DC electric field to terahertz radiation

WASHINGTON, D.C., August 4, 2015 -- Terahertz radiation, the no-man's land of the electromagnetic spectrum, has long stymied researchers. Optical technologies can finagle light in the shorter-wavelength visible and infrared range, while electromagnetic techniques can manipulate longer-wavelength radiation like microwaves and radio waves. Terahertz radiation, on the other hand, lies in the gap between microwaves and infrared, whether neither traditional way to manipulate waves works effectively. As a result, creating coherent artificial sources of terahertz radiation in ...
