Synthetic gene networks can be constructed to emulate digital circuits and devices, giving one the ability to program and design cells with some of the principles of modern computing, such as counting. A cellular counter would enable complex synthetic programming and a variety of biotechnology applications. Here, we report two complementary synthetic… (More)
Agents that modulate cellular iron availability have been studied for their antitumor activity. Based on encouraging in vitro studies, the iron chelator deferoxamine (DFO) has been used in clinical studies to treat cancer patients. The observation that DFO induced macular edema in several cancer patients led to the present investigation of vascular… (More)
Mediastinal mass syndrome (MMS) is a complex case that poses many challenges to the anesthesiologist. The cornerstone of management focuses on the potential hemodynamic changes associated with this syndrome. We describe the anesthetic management of a patient with a previously undiagnosed mediastinal mass presenting for emergency neurosurgical surgery.
