Skin Cancer Detection in Diverse Skin Tones by Machine Learning Combining Audio and Visual Convolutional Neural Networks.

Introduction: Skin cancer (SC) is common in fair skin (FS) at a 1:5 lifetime incidence for nonmelanoma skin cancer. In order to assist clinicians' decisions, a risk intervention technology was developed, which combines a dual-mode machine learning of visual and sonified (pixel to sound) data. The addition of an audio technology enhances malignant features of lesions, increases sensitivity and was previously validated under a prospective clinical setting in FS.

Effects of an acute dose of L-arginine during coronary angiography in patients with chronic renal failure: a randomized, parallel, double-blind clinical trial.

Background: Contrast media (CM) are nephrotoxic and might further worsen renal function in patients with chronic renal failure. L-Arginine, the substrate of nitric oxide, protects kidney function and may improve endothelial function in patients with coronary artery disease.

Hypothesis: Acute administration of L-arginine in a subset of patients with combined coronary artery disease and impaired kidney function during coronary angiography might prevent superimposed acute renal failure.
