  • Ideally, our compounds would be combined with other treatments to kill cancer cells faster and more efficiently - and with fewer adverse effects, which are an all-too-common problem with standard chemotherapies. (medicalnewstoday.com)
  • Cancer treatments, including chemotherapy, have helped many of those who have been diagnosed with the disease to go on to live healthy lives. (eurekalert.org)

Wattelet Distinguished Professor of Nuclear Engineering. (purdue.edu)
  • free radicals
  • When enough of these free radicals accumulate, the cell dies. (washington.edu)
  • While the body metabolizes oxygen very efficiently, 1% or 2% of cells will get damaged in the process and turn into free radicals," he says. (medicinenet.com)
  • Free radicals" is a term often used to describe damaged cells that can be problematic. (medicinenet.com)
  • When free radicals are on the attack, they don't just kill cells to acquire their missing molecule. (medicinenet.com)
  • If free radicals simply killed a cell, it wouldn't be so bad¹ the body could just regenerate another one," he says. (medicinenet.com)
  • The problem is, free radicals often injure the cell, damaging the DNA, which creates the seed for disease. (medicinenet.com)
  • Normal cell functions produce a small percentage of free radicals, much like a car engine that emits fumes. (medicinenet.com)
  • regrowth
  • Glioma has a median survival of about 15 months and a two-year survival rate of 30 per cent because it is difficult to completely remove cancer cells without compromising brain functions and chemotherapy and radiotherapy do not prevent the regrowth of remaining cancer cells. (healthcanal.com)
  • blood

(medindia.net)
  • Blood vessels in the tumor, however, have porous walls, so that the nanoparticles containing the chemotherapy can work their way into the cancerous cells. (eurekalert.org)
  • However, the nanoparticles can only reach cells that are closest to the blood vessels that carry the drug-laden particles, she said. (eurekalert.org)
  • He added that he and his team suspected that healthy cells' increased vulnerability was caused by increased blood sugar. (ecancer.org)
