PET/CT can identify new cancer lesions at early stage, allowing for prompt treatment

...nown cancer, work-ups focus on a patient's primary disease and incidental coexistence of another primary malignant lesion can be missed. "Such newly identified lesions are often of early stage and have a better likelihood of being cured if treated promptly and aggressively," indicated Wahl, the senior author...

First North American Encapsulated Islet Transplant without Long-term Immune Suppression into a Patient with Type 1 Diabetes

...storic times. Some scientists have suggested this disease could have been smallpox or even bubonic plague but bubonic plague is a bacterial disease rather than a virus and is not blocked by the CCR5-delta32 mutation. Professor Duncan commented: "T...

...that was incompletely weakened caused neurological disease symptoms after it was administered. The more widely used type of vaccine, called an inactivated vaccine, employs a killed virus to activate the horse's immune response. Osterrieder vaccinated five horses with an MLV and five with an inactivated viru...

Wong, professor and associate dean of research at the UCLA School of Dentistry and the Jonsson Comprehensive Cancer Center, the study's senior investigator. "This is a proof-of-principal study, but our results will need to ...

Turning viruses into allies against cancer

...parts of the body. "This aims to treat metastatic disease and reduce tumor recurrence," said Robert Coffin, Ph.D., chief scientific officer at Biovex Ltd. While this has not been demonstrated in patients, the approach has show promise in pre-clinical studies. In a phase I/II clinical trial, the scientists ...

MUHC scientists describe genetic resistance to rampant virus

... terminate them. "This is a new concept in natural disease resistance," notes Dr. Vidal. "Our research suggests there are many different mechanisms for fighting viruses; in the future we expect to discover additional resistant genotypes." CMV infects most of the world's organisms, including upwards of 80% o...

Scientists believe that uncovering the molecular structure of this protein will lead the way to designing drugs which enable treatment of dormant and multidrug resistant TB. In England and Wales...

From the same group, some 140 will also get non-melanoma or less serious skin cancers. “Diagnosis of skin cancers can take weeks, depending on the health sy...
