OHSU surgeon implants donated tissue allografts
04-10-2007 · EurekAlert!For many orthopedic surgeons, obtaining tissue for transplant to treat people with severe joint disorders has been difficult. But a new cooperative conceived by OHSU surgeons and administrators will make Portland, Ore., one of 16 areas across the country to receive priority allocation of fresh cartilage allografts for transplantation, allowing patients suffering from complex joint injury to be treated in a timely and effective manner.

- Freeze-dried tendon implants prove effective in early studies
01-08-2008 · EurekAlert!
Donated, freeze-dried tendon grafts loaded with gene therapy may soon offer effective repair of injured tendons, a goal that has eluded surgeons to date. According to study data published today in the journal Molecular Therapy, a new graft technique may provide the first effective framework around which flexor tendon tissue can reorganize as it heals.

- Heavy smoking cuts women's chance of pregnancy -- even with donated oocytes
11-08-2006 · EurekAlert!
Heavy smoking may reduce female fertility by directly affecting the uterus -- making it less receptive and reducing the chances the embryo will implant, according to research published on line (Thursday 9 November) in Europe's leading reproductive medicine journal Human Reproduction. This is true even if the woman is undergoing IVF with donated oocytes, demonstrating that tobacco damages the uterine lining independently of the (already known) effects of tobacco on the ovaries.

- Porous structures help boost integration of host tissue with implants, study finds
01-30-2008 · EurekAlert!
Results published today in FASEB by researchers at Columbia University, including Jeremy Mao of the Columbia College of Dental Medicine, demonstrate a novel way of using porous structures as a drug-delivery vehicle that can help boost the integration of host tissue with surgically implanted titanium.

- DNA layer reduces risk of reserve parts being rejected
03-25-2007 · EurekAlert!
Dutch researchers Jeroen van den Beucken and John Jansen have given body implants a DNA layer. This layer ensures a better attachment, more rapid recovery of the surrounding tissue and less immune responses. The older we get the more 'reserve-parts' we need. Up until now placing such parts yielded advantages, but also disadvantages such as inflammations and immune responses. Van den Beucken's invention makes it easier and more reliable to use implants and has already been patented.

- OHSU surgeon gives patients with lethal cancer reason to hope
11-30-2006 · EurekAlert!
Researchers in the OHSU Digestive Health Center are developing a system through which clinicians hope to more easily identify people at increased risk for the disease. Early identification allows physicians to identify malignancies sooner and begin aggressive treatment quicker. Only patients at high risk for pancreatic cancer will be monitored.

- Bone-growing nanomaterial could improve orthopaedic implants
09-17-2007 · EurekAlert!
Bone-forming cells grow faster and produce more calcium on anodized titanium covered in carbon nanotubes compared with plain anodized titanium and the non-anodized version currently used in orthopaedic implants, new Brown University research shows. The work, published in Nanotechnology, uncovers a new material that can be used to make more successful implants. The research also shows tantalizing promise for an all-new device: a "smart" implant that can sense and report on bone growth.

- Geisinger launches extensive study on obesity and related liver problem
04-16-2007 · EurekAlert!
Geisinger Health System researchers in Danville, Pa., are looking at the genetics of obesity through a unique study. Geisinger patients have voluntarily donated more than 600 liver tissue samples so that researchers can study obesity and also develop a safer, noninvasive way of detecting an obesity-related condition: nonalcoholic fatty liver disease. Relying on several core system resources in the study, Geisinger researchers hope to know more about nonalcoholic fatty liver disease and related health problems.
