A new bioengineering technique for creating 'off the shelf' blood vessels was unveiled today in the journal Science Translational Medicine. Researchers believe their technique might one day obviate the need to use the patient's own blood vessels to replace those that are not functioning, specifically in heart by-pass and hemodialysis surgeries, saving as many as 500,000 lives a year in the U.S. alone.
C Dots, or Cornell Dots, named for the university where they were first developed, have received approval from the U.S. Food & Drug Administration (FDA)... to be used in a human clinical trial. The C Dots were first developed as optical probes, but have since been adapted for use as cancer cell trackers, assisting both the diagnosis and targeted treatment of cancer cells.
The hyppocampus is the brain structure responsible for all memory formation. When it shrinks during aging, it is also responsible for memory loss. Researchers from four universities studied the brains of older persons who were already experiencing atrophy of the hippocampus to see if and what kind of exercise might increase the size of the hippocampus.
For the first time a surgical study using a placebo control group has been performed by researchers at the University of Gothenburg and Sahlgrenska University Hospital in Sweden on dementia patients. In this strange but important experiment, half of the patients received functional shunts and the other half non-functional shunts.
According to the World Health Organization, the number one cause of blindness in the world is age-related cataract, affecting about 18 million people. For areas that do not have adequate surgical facilities for lens replacement or for those who cannot afford such surgeries, this Chinese 60 year old non-prescription medicine just might do the trick...
Purdue University researchers have accomplished a major milestone in the engineering of a micro-model for breast cancer research. The slide-size model has been dubbed "breast on-a-chip" for its replication of the branching of the mammary duct system, where most breast cancers occur.
Melatonin is a hormone that has many functions. Produced at night by the pineal gland, it regulates the sleep-wake cycle, body temperature, blood pressure, and glucose tolerance; lack of melatonin can create serious medical problems.
