Priorities for research on pharmaceutical and personal care products in the environment

2014-09-22
(Press-News.org) PENSACOLA, Fla. – In 2011 the Society of Environmental Toxicology and Chemistry (SETAC) held a workshop for 45 international experts to identify and prioritize the scientific research needed to understand the risks of pharmaceuticals and personal care products (PPCPs) in the environment. The effort was extended, and results were published in the most recent issue of the Society's international journal, Integrated Environmental Assessment and Management (IEAM). The published work is accompanied by a podcast interviewing the lead author of the study, Murray Rudd from the University of York in the United Kingdom.

PPCPs make their way into the environment through a number of pathways, over time and at low concentrations. However, critical knowledge is missing that links the current understanding of the effects PPCPs on ecosystems and human health to the needs of society to effectively regulate and manage these chemicals in the environment. Rudd and his colleagues surveyed scientists and regulatory professional from around the world to better understand the most pressing knowledge gaps and to align strategically the most important science research goals with regulatory policy needs.

According to Rudd, the survey results revealed an emphasis on the relationship between PPCPs and non-chemical stressors such as water and soil quality. Furthermore, research on human health exposure was ranked as the highest priority, while regional identification and testing methods for measuring PPCPs in the environment were found to be the lowest priority.

In addition to research priorities, Rudd and his colleagues were surprised to find that disciplinary consistencies tended to trump geographic differences. As Rudd explains, "If you have an ecotoxicologist from India and an ecotoxicologist from Belgium, the odds are that they're going to be much closer in their priorities than people in different disciplines are going to be." Rudd notes that the illumination of cultural and disciplinary differences in survey responses has opened up "interesting opportunities for collaboration at an international level and across disciplinary collaboration that starts to involve groups that really never traditionally have worked together."

The work of Rudd and his colleagues is part of SETAC's Global Horizon Scanning Project. Launched in early 2014, the GHSP involves scientists from Africa, Asia-Pacific, Europe, Latin America, and North America with a common goal of extending this and similar research prioritization models to identify geographically specific research needs that address the impact of natural and man-made stressors on a sustainable environment.

Wildfires in Khabarovsk Krai, Russia

Wildfires in Khabarovsk Krai, Russia
2014-09-22
Most of the fires captured in this image burn in Khabarovsk Krai, a territory occupying the coastline of the Sea of Okhotsk. Dozens of red hotspots, accompanied by plumes of smoke mark active fires. The smoke, which appears mostly white or grey, blows to the east towards the Sea of Okhotsk. Taiga and tundra are found in the north of this area, swampy forest inhabit the central depression, and deciduous forests are the natural vegetation in the south. While large wildfires are common in Russia in the summer, the 2014 wildfire season appears to be more intense than usual. ...

New chip promising for tumor-targeting research

New chip promising for tumor-targeting research
2014-09-22
WEST LAFAYETTE, Ind. – Researchers have developed a chip capable of simulating a tumor's "microenvironment" and plan to use the new system to test the effectiveness of nanoparticles and drugs that target cancer. The new system, called a tumor-microenvironment-on-chip (T-MOC) device, will allow researchers to study the complex environment surrounding tumors and the barriers that prevent the targeted delivery of therapeutic agents, said Bumsoo Han, a Purdue University associate professor of mechanical engineering. Researchers are trying to perfect "targeted delivery" methods ...

Brainwave test could improve autism diagnosis and classification

2014-09-22
September 22, 2014 – (BRONX, NY) – A new study by researchers at Albert Einstein College of Medicine of Yeshiva University suggests that measuring how fast the brain responds to sights and sounds could help in objectively classifying people on the autism spectrum and may help diagnose the condition earlier. The paper was published today in the online edition of the Journal of Autism and Developmental Disabilities. The U.S. Centers for Disease Control and Prevention estimates that 1 in 68 children has been identified with an autism spectrum disorder (ASD). The signs and ...

Common diabetes drug associated with risk of low levels of thyroid hormone

2014-09-22
Metformin, a commonly used drug for treating type 2 diabetes, is linked to an increased risk of low thyroid-stimulating hormone (TSH) levels in patients with underactive thyroids (hypothyroidism), according to a study in CMAJ (Canadian Medical Association Journal). Low levels of TSH can cause harm, such as cardiovascular conditions and fractures. Metformin is used to lower blood glucose levels by reducing glucose production in the liver. However, some previous studies have raised concerns that metformin may lower thyroid-stimulating hormone levels. Researchers looked ...

University of Chicago neuroscientists challenge long-held understanding of the sense of touch

2014-09-22
Different types of nerves and skin receptors work in concert to produce sensations of touch, University of Chicago neuroscientists argue in a review article published Sept. 22, 2014, in the journal Trends in Neurosciences. Their assertion challenges a long-held principle in the field—that separate groups of nerves and receptors are responsible for distinct components of touch, like texture or shape. They hope to change the way somatosensory neuroscience is taught and how the science of touch is studied. Sliman Bensmaia, PhD, assistant professor of organismal biology and ...

Variability keeps the body in balance

2014-09-22
Although the heart beats out a very familiar "lub-dub" pattern that speeds up or slows down as our activity increases or decreases, the pattern itself isn't as regular as you might think. In fact, the amount of time between heartbeats can vary even at a "constant" heart rate—and that variability, doctors have found, is a good thing. Reduced heart rate variability (HRV) has been found to be predictive of a number of illnesses, such as congestive heart failure and inflammation. For athletes, a drop in HRV has also been linked to fatigue and overtraining. However, the underlying ...

NASA sees Tropical Depression Polo winding down

NASA sees Tropical Depression Polo winding down
2014-09-22
Infrared satellite imagery from NASA's Aqua satellite showed only a swirl of low-level clouds some deep clouds around Polo's weakening center on Sept. 22 as the storm weakened to a depression. The Atmospheric Infrared Sounder or AIRS instrument aboard Aqua gathered infrared data on Polo on Sept. 22 at 5:11 a.m. EDT, reading cloud top temperatures. There was a small area of high clouds, indicating that most thunderstorms in the depression had weakened or already dissipated except for that area. At 5 a.m. EDT on Monday, Sept. 22, Tropical Depression Polo's maximum sustained ...

Compound from hops aids cognitive function in young animals

Compound from hops aids cognitive function in young animals
2014-09-22
CORVALLIS, Ore. – Xanthohumol, a type of flavonoid found in hops and beer, has been shown in a new study to improve cognitive function in young mice, but not in older animals. The research was just published in Behavioral Brain Research by scientists from the Linus Pauling Institute and College of Veterinary Medicine at Oregon State University. It's another step toward understanding, and ultimately reducing the degradation of memory that happens with age in many mammalian species, including humans. Flavonoids are compounds found in plants that often give them their ...
