Abstract: A method for rapidly developing additive manufacturing (AM) materials includes disposing a powder layer into a powder pocket of a build device for an AM machine, executing single-line trace patterns with the AM machine on a first portion of the powder layer to form corresponding single-line traces on the build device, and executing sets of multiple-line trace patterns with the AM machine on a second portion of the powder layer to form corresponding sets of multiple-line traces on the build device.
Abstract: Itraconazole, a widely used antifungal drug, has been found to possess potent anti-angiogenic and anti-hedgehog activities, exhibiting promising antitumor activity in several human clinical studies. The wider use of itraconazole in the treatment of cancer, however, has been limited by its potent inhibition of the drug metabolic enzyme CYP3A4 which causes drug-drug interactions. In an effort to eliminate the CYP3A4 inhibition of itraconazole while retaining its anti-angiogenic activity, we synthesized a series of itraconazole derivatives. The newly synthesized analogs of itraconazole were evaluated for their cytotoxicity against human umbilical vein endothelial cells (HUVEC) and their inhibitory activity against CYP3A4 enzyme.

Abstract: A device may obtain first information relating to one or more first lung nodules identified in first imaging of a chest of a patient and second information relating to one or more second lung nodules identified in second imaging of the chest of the patient. The device may provide the first information and the second information to a machine learning model. The device may determine, using the machine learning model, a risk of lung cancer associated with the patient based on an elapsed time between performance of the first imaging and the second imaging and differences between the first information and the second information. The risk of lung cancer may have an inverse correlation to the elapsed time and a direct correlation to the differences.
