Human scabs serve as inspiration for new bandage to speed healing

2013-05-29
(Press-News.org) Human scabs have become the model for development of an advanced wound dressing material that shows promise for speeding the healing process, scientists are reporting. Their study appears in the journal ACS Applied Materials & Interfaces.

Shutao Wang and colleagues explain that scabs are a perfect natural dressing material for wounds. In addition to preventing further bleeding, scabs protect against infection and recruit the new cells needed for healing. Existing bandages and other dressings for wounds generally are intended to prevent bleeding and infections. Wang's team set out to develop a new generation of wound dressings that reduce the risk of infections while speeding the healing process.

They describe how research on the surface structure of natural scabs served as inspiration for developing a "cytophilic" wound dressing material. It attracts new cells needed for healing. The material mimics the underside of scabs, where tiny fibers are arranged in the same direction like velvet or a cat's fur. Wang's team spun fibers of polyurethane — the common durable and flexible plastic — into the same pattern. In laboratory experiments, the human cells involved in healing quickly attached to the membrane and lined up like those in actual scabs. The scientists conclude that this membrane "is of great potential in fabricating dressing materials for rapid wound healing, as well as other biomaterials, such as membrane for capturing circulating tumor cells, bone growth and constructing neural networks."

EORTC study identifies patients with anaplastic oligodendroglioma that benefit from adjuvant PCV

2013-05-29
A further report on the results of EORTC trial 26951 indicates that CpG island methylator phenotype (CIMP) status and O 6-methylguanine-DNA methyltransferase (MGMT) promoter methylation as assessed by MGMT-STP27 are the most informative for identifying grade III glioma patients who might benefit from the addition of procarbazine, CCNU and vincristine (PCV) chemotherapy to radiation therapy. Prior results had shown that PCV chemotherapy following standard radiation therapy delayed tumor growth and extended the lives of patients with anaplastic oligodendroglial tumors, a ...

Charred micro-bunny sculpture shows promise of new material for 3-D shaping

2013-05-29
Though its surface has been turned to carbon, the bunny-like features can still be easily observed with a microscope. This rabbit sculpture, the size of a typical bacterium, is one of several whimsical shapes created by a team of Japanese scientists using a new material that can be molded into complex, highly conductive 3-D structures with features just a few micrometers across. Combined with state-of-the-art micro-sculpting techniques, the new resin holds promise for making customized electrodes for fuel cells or batteries, as well as biosensor interfaces for medical uses. ...

Despite safety and other concerns, nuclear power saves lives, greenhouse gas emissions

2013-05-29
Global use of nuclear power has prevented about 1.84 million air pollution-related deaths and release of 64 billion tons of greenhouse gases that would have resulted from burning coal and other fossil fuels, a new study concludes. It appears in the ACS journal Environmental Science & Technology. Pushker A. Kharecha and James E. Hansen state that nuclear power has the potential to help control both global climate change and illness and death associated with air pollution. That potential exists, they say, despite serious questions about safety, disposal of radioactive waste ...

A new addition to the Hall of Fame of science venues

2013-05-29
A building that helped launch generations of scientists, including Nobel laureates, on their careers of discovery has joined the Hall of Fame of notable venues, being named a National Historic Chemical Landmark by the American Chemical Society (ACS). That's the topic of an article in the current edition of Chemical & Engineering News (C&EN), the weekly newsmagazine of the ACS, the world's largest scientific society. Susan J. Ainsworth, C&EN senior editor, explains that the ACS recognized the R.B. Wetherill Laboratory of Chemistry building on the Purdue University's ...

New Mayo Clinic approach could lead to blood test to diagnose Alzheimer's in earliest stage

2013-05-29
ROCHESTER, Minn. -- Blood offers promise as a way to detect Alzheimer's disease at its earliest onset, Mayo Clinic researchers say. They envision a test that would detect distinct metabolic signatures in blood plasma that are synonymous with the disease -- years before patients begin showing cognitive decline. Their study was recently published online in the journal PLOS ONE. Researchers analyzed cerebrospinal fluid and plasma samples from 45 people in the Mayo Clinic Study on Aging and Mayo Clinic Alzheimer's Disease Center (15 with no cognitive decline, 15 with mild ...

Study shows longer treatment for children with langerhans cell hystiocytosis improves survival rates

2013-05-29
Washington, DC—A new international study finds that prolonged, intense initial treatment in children with multi-system Langerhans cell histiocytosis (MS-LCH) can achieve survival rates as high as 84 percent—a full 15 percent improvement over the previous clinical trial in this series. The study, LCH-III, is published in Blood, the journal of the American Society of Hematology. It is the third in a series of international randomized clinical trials for LCH that spans twenty years initiated and coordinated by the Histiocyte Society, a group of more than 200 physicians and ...

Twitter may become less interactive and more an advertising broadcast medium like TV or radio

2013-05-29
PITTSBURGH—Popular social media site Twitter may eventually resemble a broadcast medium like television or radio, with users reading messages written by celebrities and corporations rather than writing their own "tweet" messages of up to 140 characters, suggests a new study coauthored by Andrew T. Stephen, assistant professor of business administration and Katz Fellow in Marketing in the University of Pittsburgh's Joseph M. Katz Graduate School of Business and College of Business Administration. In one of the first studies to use social media as a laboratory for social ...

People can 'beat' guilt detection tests by suppressing incriminating memories

2013-05-29
New research published by an international team of psychologists has shown that people can suppress incriminating memories and thereby avoid detection in brain activity guilt detection tests. Such tests, which are commercially available in the USA and are used by law enforcement agencies in several countries, including Japan and India, are based on the logic that criminals will have specific memories of their crime stored in their brain. Once presented with reminders of their crime in a guilt detection test, it is assumed that their brain will automatically and uncontrollably ...

Pigeons peck for computerized treat

2013-05-29
Go to about any public square, and you see pigeons pecking at the ground, always in search of crumbs dropped by a passerby. While the pigeons' scavenging may seem random, new research by psychologists at the University of Iowa suggest the birds are capable of making highly intelligent choices, sometimes with problem-solving skills to match. The study by Edward Wasserman and colleagues centered on the "string task," a longstanding, standard test of intelligence that involves attaching a treat to one of two strings and seeing if the participant (human or animal) can reel ...

Study finds that radiation oncology research is critically underfunded by NIH

2013-05-29
Radiation oncology research received 197 grants, totaling only 1.6 percent ($85.5 million) of the $5.4 billion in cancer research funding from the National Institutes of Health (NIH) in Fiscal Year (FY) 2013, according to a study available online and in the June 1, 2013, print issue of the International Journal of Radiation Oncology • Biology • Physics (Red Journal), the official scientific journal of the American Society for Radiation Oncology (ASTRO). The study reviewed the more than 50,000 grants funded by the NIH, totaling $30.9 billion. Investigation revealed 952 ...
