Stem cells inside sutures could improve healing in Achilles tendon injuries

2014-03-12
(Press-News.org) Los Angeles, CA (March 12, 2014) Researchers have found that sutures embedded with stem cells led to quicker and stronger healing of Achilles tendon tears than traditional sutures, according to a new study published in the March 2014 issue of Foot & Ankle International (published by SAGE).

Achilles tendon injuries are common for professional, collegiate and recreational athletes. These injuries are often treated surgically to reattach or repair the tendon if it has been torn. Patients have to keep their legs immobilized for a while after surgery before beginning their rehabilitation. Athletes may return to their activities sooner, but risk rerupturing the tendon if it has not healed completely.

Drs. Lew Schon, Samuel Adams, and Elizabeth Allen and Researchers Margaret Thorpe, Brent Parks, and Gary Aghazarian from MedStar Union Memorial Hospital in Baltimore, Maryland, conducted the study. They compared traditional surgery, surgery with stem cells injected in the injury area, and surgery with special sutures embedded with stem cells in rats. The results showed that the group receiving the stem cell sutures healed better.

"The exciting news from this early work is that the stem cells stayed in the tendon, promoting healing right away, during a time when patients are not able to begin aggressive rehabilitation. When people can't fully use their leg, the risk is that atrophy sets in and adhesions can develop which can impact how strong and functional the muscle and tendon are after it is reattached," said Dr. Schon. "Not only did the stem cells encourage better healing at the cellular level, the tendon strength itself was also stronger four weeks following surgery than in the other groups in our study," he added.

The AOFAS promotes quality, ethical and cost-effective patient care through education, research and training of orthopaedic surgeons and other health care providers. It creates public awareness for the prevention and treatment of foot and ankle disorders, provides leadership, and serves as a resource for government, industry and the national and international health care community.

Orthopaedic Foot and Ankle Surgeons are medical doctors (MD and DO) who specialize in the diagnosis, care, and treatment of patients with disorders of the musculoskeletal system of the foot and ankle. This includes the bones, joints, ligaments, muscles, tendons, nerves and skin. Orthopaedic foot and ankle surgeons use medical, physical, and rehabilitative methods as well as surgery to treat patients of all ages. They perform reconstructive procedures, treat sports injuries, and manage and treat trauma of the foot and ankle.

Orthopaedic foot and ankle surgeons work with physicians of many other specialties, including internal medicine, pediatrics, vascular surgery, endocrinology, radiology, anesthesiology, and others. Medical school curriculum and post-graduate training proves the solid clinical background necessary to recognize medical problems, admit patients to a hospital when necessary, and contribute significantly to the coordination of care appropriate to each patient.

Computer model predicts vastly different ecosystem in Antarcticas Ross Sea in the coming century
2014-03-12
The Ross Sea, a major, biologically productive Antarctic ecosystem, "clearly will be extensively modified by future climate change" in the coming decades as rising temperatures and changing wind patterns create longer periods of ice-free open water, affecting the life cycles of both predators and prey, according to a paper published by researchers funded by the National Science Foundation (NSF). To make their predictions, the researchers used information drawn from the Regional Ocean Modeling System, a computer model of sea-ice, ocean, atmosphere and ice-shelf interactions. ...

NASA sees ex-Tropical Cyclone Gillian in Australias Gulf of Carpentaria
2014-03-12
Tropical Cyclone Gillian made landfall on the western Cape York Peninsula of Queensland, Australia, weakened and has now meandered back over water. On March 12, NASA-NOAA's Suomi NPP satellite captured an image of the remnants in the southern Gulf of Carpentaria. On March 12 at 0600 UTC/2 a.m. EST, the remnants of Tropical Cyclone Gillian were located near 16.0 south and 141.1 east, about 115 nautical miles/ 132.3 miles/213 km east-northeast of Mornington Island in the Gulf of Carpentaria. According to the Joint Typhoon Warning Center or JTWC maximum sustained surface ...

Tropical Cyclone Lusi reached hurricane force as NASA's Aqua satellite passed overhead early on March 12. The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite captured a visible image of Tropical Cyclone Lusi that showed the storm's western quadrant affecting Vanuatu on March 12 at 02:05 UTC. In the MODIS image, Lusi had the distinct comma shape of a mature tropical cyclone, however no eye was visible. However, animated multispectral satellite imagery does show a ragged eye with tightly curved bands of thunderstorms wrapping ...

Sound trumps meaning in first language learning

2014-03-12
(Washington, DC) – A new study reveals that four-to-seven-year-old children rely on the sounds of new nouns more than on their meaning when assigning them to noun classes, even though the meaning is more predictive of noun class in the adult language. This finding reveals that children's sensitivity to their linguistic environment does not line up with objective measures of informativity, highlighting the active role that children play in selecting the data from which they learn language. The study, "Statistical Insensitivity in the Acquisition of Tsez Noun Classes," ...

SALT LAKE CITY, March 12, 2014 – University of Utah chemists discovered how vibrations in chemical bonds can be used to predict chemical reactions and thus design better catalysts to speed reactions that make medicines, industrial products and new materials. "The vibrations alone are not adequate, but combined with other classical techniques in physical organic chemistry, we are able to predict how reactions can occur," says chemistry professor Matt Sigman, senior author of the study in the Thursday, March 13, issue of the journal Nature. "This should be applicable ...

IRX3 is likely the 'fat gene'

2014-03-12
Mutations within the gene FTO have been implicated as the strongest genetic determinant of obesity risk in humans, but the mechanism behind this link remained unknown. Now, an international team of scientists has discovered that the obesity-associated elements within FTO interact with IRX3, a distant gene on the genome that appears to be the functional obesity gene. The FTO gene itself appears to have only a peripheral effect on obesity. The study appears online March 12 in Nature. "Our data strongly suggest that IRX3 controls body mass and regulates body composition," ...

Water-rich gem points to vast oceans beneath the Earth: UAlberta study
2014-03-12
A University of Alberta diamond scientist has found the first terrestrial sample of a water-rich gem that yields new evidence about the existence of large volumes of water deep beneath the Earth. An international team of scientists led by Graham Pearson, Canada Excellence Research Chair in Arctic Resources at the U of A, has discovered the first-ever sample of a mineral called ringwoodite. Analysis of the mineral shows it contains a significant amount of water—1.5 per cent of its weight—a finding that confirms scientific theories about vast volumes of water trapped 410 ...

The team of Francesca Ferlaino, Institute for Experimental Physics of the University of Innsbruck, Austria, has experimentally shown chaotic behavior of particles in a quantum gas. "For the first time we have been able to observe quantum chaos in the scattering behavior of ultracold atoms," says an excited Ferlaino. The physicists used random matrix theory to confirm their results, thus asserting the universal character of this statistical theory. Nobel laureate Eugene Wigner formulated random matrix theory to describe complex systems in the 1950s. Although interactions ...
