Amino-functionalized carbon nanotubes act as a carrier for nerve growth factor

Amino-functionalized carbon nanotubes act as a carrier for nerve growth factor
2014-04-21
(Press-News.org) In recent years, there are growing studies concerning the use of different carrier materials for sustained-release and controlled-release of nerve growth factor in neuroscience research. In a study by Prof. Gao Li and team from Tongji Medical College, Huazhong University of Science and Technology in China, amino-functionalized ethylenediamine-treated multi-walled carbon nanotubes were used to prepare carbon nanotubes-nerve growth factor complexes by non-covalent grafting. Results showed that amino functionalization improved carbon nanotubes-nerve growth factor complex dispersibility, reduced their toxicity to PC12 cells, and promoted PC12 cell differentiation and chick embryo dorsal root ganglion. This study has been reported in the Neural Regeneration Research (Vol. 9, No. 3, 2014).

People selectively remember the details of atrocities that absolve in-group members

2014-04-21
Conversations about wartime atrocities often omit certain details. According to research published in Psychological Science, a journal of the Association for Psychological Science, these omissions can lead people to have different memories for the event depending on social group membership. "We started thinking about this project around the time when stories began to emerge in the popular media about atrocities committed by American soldiers in Iraq and Afghanistan," says lead researcher Alin Coman, psychological scientist at Princeton University. "We wanted to scientifically ...

A new key to unlocking the mysteries of physics? Quantum turbulence

2014-04-21
The recent discovery of the Higgs boson has confirmed theories about the origin of mass and, with it, offered the potential to explain other scientific mysteries. But, scientists are continually studying other, less-understood forces that may also shed light on matters not yet uncovered. Among these is quantum turbulence, writes Katepalli Sreenivasan, an NYU University Professor, in a special issue of Proceedings of the National Academy of Sciences. Sreenivasan's introductory analysis, written with issue co-editors Carlo Barenghi of Newcastle University and Ladislav ...

Mental illness not usually linked to crime, research finds

2014-04-21
WASHINGTON — In a study of crimes committed by people with serious mental disorders, only 7.5 percent were directly related to symptoms of mental illness, according to new research published by the American Psychological Association. Researchers analyzed 429 crimes committed by 143 offenders with three major types of mental illness and found that 3 percent of their crimes were directly related to symptoms of major depression, 4 percent to symptoms of schizophrenia disorders and 10 percent to symptoms of bipolar disorder. "When we hear about crimes committed by people ...

Teachers' scare tactics may lead to lower exam scores

2014-04-21
WASHINGTON -- As the school year winds down and final exams loom, teachers may want to avoid reminding students of the bad consequences of failing a test because doing so could lead to lower scores, according to new research published by APA. "Teachers are desperately keen to motivate their students in the best possible way but may not be aware of how messages they communicate to students around the importance of performing well in exams can be interpreted in different ways," said lead author David Putwain, PhD, of Edge Hill University in Lancashire, England. The study, ...

Ginseng can treat and prevent influenza and RSV, researcher finds

2014-04-21
ATLANTA--Ginseng can help treat and prevent influenza and respiratory syncytial virus (RSV), a respiratory virus that infects the lungs and breathing passages, according to research findings by a scientist in Georgia State University's new Institute for Biomedical Sciences. In a recent issue of Nutrients and an upcoming publication of the International Journal of Molecular Medicine, Sang-Moo Kang reports the beneficial effects of ginseng, a well-known herbal medicine, on human health. Kang's primary research focuses on designing and developing effective vaccines against ...

New material coating technology mimics nature's lotus effect

New material coating technology mimics natures lotus effect
2014-04-21
VIDEO: This movie explains the new coating material. Click here for more information. Ever stop to consider why lotus plant leaves always look clean? The hydrophobic – water repelling – characteristic of the leaf, termed the "Lotus effect," helps the plant survive in muddy swamps, repelling dirt and producing beautiful flowers. Of late, engineers have been paying more and more attention to nature's efficiencies, such as the Lotus effect, and studying its behavior in order ...

Birthplace of the domesticated chili pepper identified in Mexico

2014-04-21
Central-east Mexico gave birth to the domesticated chili pepper — now the world's most widely grown spice crop — reports an international team of researchers, led by a plant scientist at the University of California, Davis. Results from the four-pronged investigation — based on linguistic and ecological evidence as well as the more traditional archaeological and genetic data — suggest a regional, rather than a geographically specific, birthplace for the domesticated chili pepper. That region, extending from southern Puebla and northern Oaxaca to southeastern Veracruz, ...

Study: Centuries of sand to grow Mississippi Delta

Study: Centuries of sand to grow Mississippi Delta
2014-04-21
The wetlands of the Mississippi River Delta are slowly sinking and rapidly eroding, but new research from Rice University and the University of South Carolina has found the river's supply of sand -- the material engineers most need to rebuild the delta -- will stay constant for centuries. The new study, which appears online this week in Nature Geoscience, is encouraging news for scientists and government officials who are working to shore up southeastern Louisiana's rapidly disappearing wetlands. The delta sinks each year as its soil settles and becomes more compact. ...

A protein required for integrity of induced pluripotent stem cells

A protein required for integrity of induced pluripotent stem cells
2014-04-21
Cell reprogramming converts specialised cells such as nerve cells or skin cells towards an embryonic stem cell state. This reversal in the evolutionary development of cells also requires a reversal in the biology of telomeres, the structures that protect the ends of chromosomes; whilst under normal conditions telomeres shorten over time, during cell reprogramming they follow the opposite strategy and increase in length. A study published today in the journal Stem Cell Reports, from the Cell Publishing Group, reveals that the SIRT1 protein is needed to lengthen and maintain ...

New approach may help manage the most troubling symptoms of dementia, lessen use of drugs

2014-04-21
ANN ARBOR, Mich. — A new approach to handling agitation, aggression and other unwanted behaviors by people with dementia may help reduce the use of antipsychotics and other psychiatric drugs in this population, and make life easier for them and their caregivers, a team of experts says. Publishing their recommendations under the easy-to-remember acronym of "DICE", the panel of specialists in senior mental health hope to spark better teamwork among those who care for dementia patients at home, in residential facilities and in hospitals and clinics. In fact, the federal ...
