Creating brain cells from bone marrow

...one marrow cells which opens up the possibility of grafts for Parkinson's disease. At the Peterson Medical College scientists grew stem cells from adult bone marrow in a finely-tuned cocktail of growth factors and other chemicals and found they could get them to convert into neurons. Normally such stem ce...

Older Men Surviving Coronary Bypasses

...grafts," says Pell. "We know that the use of these grafts has increased over that period." Also helping to boost the survival rates, according to Pell, are improvements in "secondary prevention," meaning post-surgical drug treatments and changes in diet, exercise and lifestyle, including quitting smoking....

Parasite infections linked to organ transplants

...turned up 26 bacterial infections traced to tissue grafts that had come from cadavers in the United States. This shows that the graft-related infections show an urgent need to update federal regulations and industry standards for preventing contamination. In the report involving the parasitic disease, all ...

Surgery-Rigged pulley helps patients

...r forward, and then hold them in the new spot with grafts from hip or rib bones. Some children have such little bone to work with that they can't complete such surgery until they're teen-agers. And if the graft is poorly placed, it can't be moved. Enter Poll's alternative. It sounds traumatic. After all, A...

Stem Cells Found To Offer Promise For Hair Growth

... may be able to isolate and use stem cells in skin grafts for burn patients, generating better grafts with hairs....

Operating on a Beating Heart Yields Better Results For Blocked Heart Arteries

...s . Researchers assigned 400 patients with bypass grafts to undergo either on-pump (work of the heart is sh...o similar in both groups. Reblockage in leg bypass grafts was 41 percent in the off-pump group and 51 percent in the on-pump group. Based on findings of the ...

Twisted bypass grafts work better

... results of the tests have shown that conventional grafts had thickened blood that had also coagulated, but the new shunts looked as good as new since they were grafted. Reference: Journal of the Royal Society Interface, June 2005...

Grafting arteries to restore blood flow is best for survival

...ies have more life span when they undergo arterial grafts that will restore blood flow to all areas of the heart. Incomplete artery grafting may not increase the lifespan of the patients sufficiently outside the hospital stay. Researchers feel that the current tendency of considering only the hospital stay...

Cardiac bypass seems to be favoring men more than women

...es or veins from other parts of your body — called grafts — and using them to reroute the blood around the clogged artery. Women have a 22 percent greater risk of dying during or immediately after a heart bypass than men, according to a recent study that analyzed the treatment outcomes in either sex. Card...

Stem cell therapy for developing new trachea using Tissue engineering

...re tubes, with the required nutrients and when the grafts with the engineered tissues were ready they were reconstructed on to the lambs. Four to five weeks later, the lambs were born, and all five lambs that survived to term were able to breathe spontaneously at birth, four of them with no sign of respirat...

A Novel Method For Measuring Interstitial Fluid Pressure In Cancer Tissues

...chnique, the authors compared IFP in skin melanoma grafts in NG2 knockout and wild-type mice. Knocking out NG2 proteoglycan on vasculogenic and angiogenic pericytes was found to reduce interstitial fluid pressure in melanoma. This study also demonstrates that IFP is elevated in skin melanoma. The simplifi...

Another Potential Of Stem Cells Discovered: Used For Growing Cartilage

...have to cut away parts of cartilage, and then take grafts from other parts of the body. With this new technique doctors would potentially be able to take stem cells from the patient, grow them in a laboratory, and then transplant them after the surgery. The research, carried out by a team at Imperial Coll...

Doctors Finish Mother-To-Son Nerve Surgery

...at previously would have been lost. In some cases, grafts can be taken from other parts of the body, but in Anderson's case, the loss of his leg meant there wasn't enough donor nerve to use, Belzberg said. Anderson's mother, Frankie Anderson, 40, had nerve segments removed from each arm and leg on Tuesday,...

Drug-Eluting Stents Ensure Patency Of The Saphenous Vein Grafts

...s in the heart (coronary arteries). However, these grafts become old over a period of time. Infact nearly 50% of all vein grafts become diseased, necessitating a second intervention in the form of either a repeat open-heart surge...

Widespread Commercialisation Of Human Organ Donation In China

Despite reports of poor survival rates of grafts transplanted from total strangers (were paid for their donation) and transmission of HIV, such instances of commercialisation of human organs continue to expose the deficits in the legal, social and ethical perspective with respect to human transplan...

Plastic Surgeons Looking Forward To First Full Face Transplant

...overing severe burns and other trauma." Previously grafts and skin patches have been used to reconstruct the face, but these are not ideal processes since they leave ugly patches and scars. In the current study, five hours were needed to perform the transplant from one cadaver to another, "Plastic surgeons ...

Researchers Create Bladder In The Lab

In the current study, researchers used the patients’ own cells to create a bladder in the laboratory and then grafted the same onto the existing bl...

PI-103 Effective against Brain Cancer

... tumor. In animal studies (mice) with human glioma grafts the drug is found to be potent against proliferating cancer cells. The unique effectiveness of PI-103 stems from its ability to attack two separate steps in the series of signals that trigger the spread of cancer. The dual blockade proved to be a saf...

Fine Polymer Scaffolding – a Boon for Skin Reconstructio

...urns where surgeons are unable to take enough skin grafts from elsewhere on the body to cover the damaged areas. Currently, bovine collagen** or skin from human donors is used in these cases, but these approaches have potential health and rejection risks. ‘Simplicity is the key,’ says Professor Tony Ryan,...
