... and joking while his chest was opened and the two grafts were sewen, Raguram said. According to Dr.S.Kumar, Chief Cardiac Anesthesiologist of MMHRC, this was made possible because the patient's pain sensation was completely arrested in the operation site by selectively blocking nerves using a strategicall...

A New Approach to Heart Bypass Surgery Provides Patients with 'One-stop Shopping'

...end of routine cardiac surgical cases to make sure grafts are in place and blood is flowing properly. Traditionally, a “before picture” was obtained prior to surgery, but an X-ray study after procedures are completed was not the standard of care. John Byrne, M.D., likens the Hybrid OR to the change seen ...

Special Section of JCS Addresses Vascular Anomalies

...cular lesions, modern surgical techniques and skin grafts provide good results. If these procedures are done in childhood, any resulting scars are more easily managed by plastic surgery later on. In some situations, certain drug therapies may play a role. Several articles in the Special Section outline th...

Human Stem Cells Delay Start of Lou Gehrig’s Disease in Rat

...periments offer “proof of principle” for stem cell grafts and that a more complete transplant of cells - already being planned -- along the full length of the spine to affect upper body nerves and muscles as well might lead to longer survival in the same rats. “We only injected cells in the lower spine, a...

A New Option For AIDS Treatment - Radioimmunotherapy

...cted. The lack of immune systems ensured that the grafts were not rejected. The researchers bound radioactive particles such as bismuth 213 and rhenium 188 , to the antibodies and injected them into some of the mice. These antibodies target a molecule known as GP41, specific to the HIV virus carrying ...

MIT Creates 3-D Scaffold for Growing Stem Cells

...issues used in regenerative medicine, such as skin grafts or neurons to replace brain cells lost to injury or disease. The scaffold itself can be transplanted directly into the body with no ill effects. "The time has come to move on from two-dimensional dishes to culture systems that better represent th...

Mike Farrar, the chief executive of NHS North West said that incentives should be based on the quality of care provided to t...

New Protein Inhibitor Halts Growth Of Cancerous Cells

...ancers, and it inhibited the growth of human tumor grafts in mice, resulting in the death of tumor cells and regression of large tumors. The authors report that BI 2536 has now been brought into use in clinical studies of patients with locally advanced or metastatic cancers in order to address the therap...

Researchers Discover Potential Targets To Reduce Risk Of Stem Cell Transplants

...ells to prevent relapse. But, poorly matched donor grafts can be rejected, just as in organ transplants, or cause GvHD. "Currently, suitable donors can only be found for 20 to 30 percent of patients who might be cured by allogeneic transplants," said Kerr. "But by learning which genes control graft rejectio...

Artificial Vein to Boost Surgery and Ease Patient Trauma

...use heart attacks and strokes. Though synthetic grafts have been developed for use in operations to bypass clogged blood vessels many get clogged up with fatty deposits themselves, and often fail within two years, causing surgeons to rely on taking blood vessels from the patient's body. Tests on 22 pa...

New Blood Vessels can Be Created from Bone Marrow Stem Cells: Study

...atory, the study provides an alternative to venous grafts that are routinely done in patients undergoing coronary bypass operations, the disadvantages of which include limited availability of vessels, pain and discomfort at the donor site, and a high 10-year failure rate. During the course of study, the r...

Chemical Injections for Fat Removal
