For one Stanford doctor, the beat goes on during open-heart surgery

In a Stanford Hospital surgery room on a recent afternoon, heart surgeon Kai Ihnk...MD, clinical assistant professor of cardiothoracic surgery at the Stanford University School of Medicine, was using an innovative technique called "beating-hea...

Canine cancer vaccine program shows early promise

... against the melanoma cells. Dogs that first had surgery for their melanoma and then received vaccine lived cancer-free for approximately twice as long as dogs in previous studies that did not receive the vaccine. Further work is needed to improve the vaccine so that a higher percentage of dogs with melan...

Neurons find their place in the developing nervous system with the help of a sticky molecule

... To do this, they painstakingly performed in utero surgery on embryonic mice ?injecting an interfering RNA molecule into the lateral ventricle, a fluid-filled space next to the neocortex. Application of an electrical current forced the RNA into neural progenitor cells, and it was subsequently inherited by th...

Liver cancer linked to cellular repair pathway

...people with advanced liver disease are too ill for surgery to remove tumors," Sicklick said. "There is a desperate need for effective anticancer treatments that are safe for patients with liver disease." The results will be published in the April 4, 2006, issue of Carcinogenesis. The research was funded by ...

Genetic key to growth of new arteries is identified

...rves Sarkar, who is also an assistant professor of surgery at the University of California, San Francisco. "So it's very important to understand the normal process that allows an animal or a person to grow new arteries when their legs don't get good blood flow. Legs are a big problem, because if you don't ha...

Preclinical study of a new brain tumor therapy

...e few existing options aside from chemotherapy and surgery to remove the tumor, and it is rare that these treatments stop the cancer from recurring. Given the prevalence of EGFR in cells of other cancer types (such as breast cancer and lung cancer), the approach pioneered in this study may be applicable to o...

Researchers use 'trickery' to create immune response against melanoma

...early stage is usually treated by a combination of surgery and radiotherapy; more advanced cases are treated with radiotherapy and hormonal therapies such as the anti-androgens. In patients with metastatic disease where the cancer has spread to other parts of the body, a multi-disciplinary approach which cou...

Study shows combination of immune substances to be safe

...tor William E. Carson, III, associate professor of surgery and associate director for clinical research at the Ohio State University Comprehensive Cancer Center. "We were initially concerned that the addition of IL-12 might increase that toxicity. Instead, we found that the two drugs can be used together w...

Gene expression profile helps predict chemotherapy response in ovarian cancer patients

(Second-look surgery is currently the most sensitive investigational approach for detecting residual disease in patients with advanced ovarian cancer who have achieved a complete clinical remission following chemotherapy, explains Cannistra.) The expression of 93 genes,...

MUHC investigators search for the root of sexual pain in women

The new CIHR grant will allow the team to initiate research with groups of women that suffer from genital pain associated with menopause--one of the mos...

New battery technology helps stimulate nerves

... But lithium batteries don't last forever and new surgery to maintain many devices seeded into the body is required, as it is to replace batteries and devices at the end of their lives. Moreover, a new generation of tiny electrical devices to stimulate the nervous system, treat incontinence and overcome mus...
