Ultrasound imaging of chitosan nerve conduits that bridge sciatic nerve defects in rats

Ultrasound imaging of chitosan nerve conduits that bridge sciatic nerve defects in rats
2014-08-18
(Press-News.org) New simple and effective methods are needed to better evaluate the outcomes of repair using nerve conduits in vivo. Ultrasound is a common noninvasive clinical detection modality that has been used in many fields. However, ultrasound has only rarely been used to observe implanted nerve conduits in vivo. Hongkui Wang and co-workers from Affiliated Hospital of Nantong University report the first use of ultrasound to noninvasively observe the changes in chitosan nerve conduits implanted in rats over time. The ultrasound imaging clearly showed whether there are unsatisfactory complications after implantation, such as fracture, collapse, bleeding, or unusual swelling of the nerve conduits; and reflected the degradation mode of the nerve conduit in vivo over time. Ultrasound, as a noninvasive imaging modality, can be used as a supplementary observation method during conventional animal experiments on peripheral nerve tissue engineering. The relevant study has been published in the Neural Regeneration Research (Vol. 9, No. 14, 2014).

An inside-out vein graft filled with PRP for repair of a short sciatic nerve defect

2014-08-18
Platelet-rich plasma (PRP) containing various growth factors can promote nerve regeneration. An inside-out vein graft can substitute nerve autograft to repair short nerve defects. It is hypothesized that an inside-out vein graft filled with platelet-rich plasma shows better effects in the repair of short sciatic nerve defects. In a study reported on the Neural Regeneration Research (Vol. 9, No. 14, 2014), an inside-out vein autograft filled with platelet-rich plasma was used to bridge a 10 mm-long sciatic nerve defect in rats. At 6 and 8 weeks, the sciatic nerve function ...

Club cells are 'bad guys' during flu infection

Club cells are bad guys during flu infection
2014-08-18
A specialized subset of lung cells can shake flu infection, yet they remain stamped with an inflammatory gene signature that wreaks havoc in the lung, according to a study published in The Journal of Experimental Medicine. Seasonal flu is caused by influenza virus, which can infect a variety of cell types in the lung. Infected cells are typically destroyed by the virus itself or by immune cells that attack infected cells. The resulting inflammation can linger on long after the virus has been eliminated leading to persistent symptoms and, in some cases, severe tissue damage. Club ...

Myc inhibition is an effective therapeutic strategy against most aggressive brain tumors

Myc inhibition is an effective therapeutic strategy against most aggressive brain tumors
2014-08-18
Barcelona, 18 August 2014. Research led by the Vall d'Hebron Institute of Oncology (VHIO) evidence the most conclusive preclinical results to-date validating Myc inhibition as a therapeutic strategy in glioma – a highly agressive tumor type that notoriously outsmarts current anti-cancer therapies. The study led by Laura Soucek, Principal Investigator of VHIO´s Mouse Models of Cancer Therapies Group, published today in Nature Communications, not only represents an important step forward in ultimately providing brain glioma patients with new therapeutic avenues, but also ...

Sun's activity influences natural climate change

2014-08-18
For the first time, a research team has been able to reconstruct the solar activity at the end of the last ice age, around 20,000-10,000 years ago, by analysing trace elements in ice cores in Greenland and cave formations from China. During the last glacial maximum, Sweden was covered in a thick ice sheet that stretched all the way down to northern Germany and sea levels were more than 100 metres lower than they are today, because the water was frozen in the extensive ice caps. The new study shows that the sun's variation influences the climate in a similar way regardless ...

Antibiotics in early life may alter immunity long-term

2014-08-18
New University of British Columbia research found that receiving antibiotic treatments early in life can increase susceptibility to specific diseases later on. Most bacteria living in the gut play a positive role in promoting a healthy immune system, but antibiotic treatments often do not discriminate between good and bad bacteria. The study published today in Journal of Allergy and Clinical Immunology helps scientists understand how different antibiotics affect good bacteria. "This is the first step to understanding which bacteria are absolutely necessary to develop ...

Promising ferroelectric materials suffer from unexpected electric polarizations

Promising ferroelectric materials suffer from unexpected electric polarizations
2014-08-18
UPTON, NY—Electronic devices with unprecedented efficiency and data storage may someday run on ferroelectrics—remarkable materials that use built-in electric polarizations to read and write digital information, outperforming the magnets inside most popular data-driven technology. But ferroelectrics must first overcome a few key stumbling blocks, including a curious habit of "forgetting" stored data. Now, scientists at the U.S. Department of Energy's Brookhaven National Laboratory have discovered nanoscale asymmetries and charge preferences hidden within ferroelectrics ...

International scientific team criticizes adoption of 'novel ecosystems' by policymakers

International scientific team criticizes adoption of novel ecosystems by policymakers
2014-08-18
Embracing "novel" ecosystems is dangerous, according to a new study by an international team. Novel ecosystems arise when human activities transform biological communities through species invasions and environmental change. They are seemingly ubiquitous, and thus many policymakers and ecologists argue for them to be accepted as the "new normal"—an idea the researchers say is a bad one. In the study, published in the September edition of the academic journal Trends in Ecology and Evolution, the international team argues that adopting novel ecosystems is based on faulty, ...

Visual 'gist' helps us figure out where a crowd is looking

2014-08-18
Have you ever seen a crowd of people looking off into the distance, perhaps toward a passing biker or up to the top of a building? There's a good chance you looked there, too, instantly, even without paying attention to the individuals in the group. How can we tell where a crowd is looking with so little effort? Researchers at the University of California, Berkeley and the University of Denver have discovered that we rely on a specialized visual process known as "ensemble coding" to perceive where a crowd is looking. Their new study shows that we are able to tell where ...

Prioritizing suicide research can help lead to fewer suicide attempts and deaths

2014-08-18
Ann Arbor, MI, August 18, 2014 – In a new supplement to the September issue of the American Journal of Preventive Medicine, experts address the state of the science on suicide prevention and provide useful recommendations for research to inform effective suicide prevention. Suicide has been a challenging and perplexing public health issue to study as it has many dimensions and underlying factors. Although much is known about the patterns and potential risk factors of suicide, the national suicide rate does not appear to have dropped over the last 50 years. This groundbreaking ...

IU study: Parents' vaccine intentions influenced by how benefits are communicated

IU study: Parents vaccine intentions influenced by how benefits are communicated
2014-08-18
INDIANAPOLIS -- How do parents decide whether to vaccinate their child? In a study designed to formally look at the content of parent-targeted communications about the benefits of vaccination for measles, mumps and rubella, Indiana University School of Medicine investigators report that the framing of these messages influences parents' intentions to immunize their children. The investigators report that parents who viewed informational material highlighting direct benefits to their own child were the most likely to subsequently indicate that they would have their baby ...
