Evidence of harmful effect of bisphenol A-based plastics

Complex mechanism of action "Our research provides further evidence that the physiological effects of bisphenol A may be even more complex than previously assumed," says Prof Dr Raphael Stoll, head of Biomolecular Spectroscopy at the Ruhr-Universität. "However, we have also discovered other related compounds that indicate which path the future development of pharmaceutically effective substances against GTPase-mediated tumours may take," adds synthetic chemist Prof Dr Jürgen Scherkenbeck from Wuppertal. Bisphenol A impairs the function of GTPases Small GTPases are enzymes that occur in two states within the cell: in the active form when bound to the GTP molecule; and in the inactive form when bound to GDP, a lower-energy form of GTP. …

Costs for complications from cancer surgical care extremely high

The authors’ findings come against the backdrop of rising cancer care costs in the United States, which were estimated at $124.6 billion in 2010 and could rise by 66 percent to $207 billion by 2020. "It is widely known that outcomes after cancer surgery vary widely, depending on interactions between patient, tumor, neoadjuvant therapy and provider factors," said Marah Short, a senior research analyst for the Baker Institute’s Health Policy Forum. "An area of cancer care that has received little attention is the influence of complications on medical outcomes and costs of care…

MR-guided ultrasound offers noninvasive treatment for breast cancer

MR-guided focused ultrasound (MRgFUS) ablation is a noninvasive technique that requires no incision or puncture to perform. Instead, it uses the acoustic energy from high-intensity focused ultrasound to remove, or ablate, diseased tissue. Continuous MRI is used to locate the lesions and monitor the temperature change during the ablation process. …
