Philadelphia Researchers Found A Novel Way To Fight Several Kind of Cancers

...replicate within the tumor cell. When enough viral particles are produced, the tumor will burst, releasing the virus. In animal experiments, this experimental therapy, called lytic induction therapy, results in tumor death. As the first step in this study, researchers screened a wide variety of drugs to see...

Natural Milk Protein Could Lead to Super Nutritious Foods

...g, studied “casein micelles,” which are nano-sized particles of casein, a protein present in milk and responsible for the transfer of body-building nutrients from mother to baby. They encapsulated vitamin D (which plays a major role in calcium absorption and utilization in the body) in the micelles. The findin...

Researchers Develop Resin Beads That Capture Mad Cow Disease Agent From Blood
