Virologist finds contagious equine flu in dogs

...g with equine influenza use cell lines from canine kidney cells. When Dubovi first received the University of Florida samples, he and his colleagues isolated a virus and determined that it was an influenza not typically found in dogs. The next step was to test to see if it was an avian flu virus, like the...

Gene therapy to lower blood pressure just enough

...vessels. ANP also improves the manner in which the kidney eliminates sodium or salt from the body and inhibits other systems, such as the sympathetic nervous system, believed linked to development of high blood pressure. "This makes ANP an attractive agent for use in treating blood pressure," said O'Malle...

Monkeying around to improve organ transplantation

...Reinfusion of these cells into the recipient after kidney transplantation leads to very prolonged ?80 days?and perhaps even indefinite graft survival in three long-surviving animals without administration of additional immunosuppressive agents. This study shows for the first time that anergic T cells genera...

Genetically engineered animals help in scientific research that may benefit children

...iven researchers new insight in the development of kidney disease. This research is published in the September issue of Kidney International. "Chronic kidney disease is difficult to study since it takes a fair amount of time to install," states Joost P. Scha...

Stem cells bring fast direct improvement, without differentiation, in acute renal failure

...the kidneys, such "insults" lead to destruction of kidney tubular and vascular cells, initiating a significant inflammatory response. Recovery of kidney function that is adequate for patient survival depends primarily on the protection and regeneration ...

Virus uses tiny RNA to evade the immune system

... a relatively harmless monkey virus that can cause kidney infections in its natural simian host. In rodents, however, it can cause cancer. Although the SV40 genome has been found in some human tumors, its role in human cancer has been debated. The virus is better known as a model system that has greatly con...

Hurricane aftermath: Infectious disease threats from common, not exotic, diseases

... the E. coli H7:O157 strain that can cause serious kidney disease and bloody diarrhea. "At this point in time, I think it is just common sense to continue drinking only bottled water unless authorities have tested the water now being piped into some facilities and have declared it safe to drink," says Berk...

Minimally Invasive Cancer Treatments Highlighted

...en and the tenth in women. The most common type of kidney cancer is renal cell carcinoma. Interventional radiology treatments provide minimally invasive options for patients who are not good surgical candidates. Study of note: ?A prospective study of MRI-guided cryoablation of 44 renal tumors shows that 96...

University of Delaware researchers develop cancer 'nanobomb'

Horse antibodies against the bird flu virus H5N1 are effective as treatment in mice

...gues from other institutions in China infected dog kidney cells in vitro with a lethal dose of H5N1 and simultaneously exposed the cells to horse antibodies against H5N1.
