What Can Neuroscience Learn From Contemplative Practices originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and better understand the world. Answer by Brett Wingeier, CTO and co-founder of Halo. Recent research in neuroscience. other practices can help build a sense of community. Community walks, in which students lead tours of the neighborhoods surrounding
Herein we developed a new “smart” Gd-based MR contrast agent (i.e., 1) which is susceptive to furin, a protease overexpressed in tumor. Under the action of furin, 1 condenses to form dimers (1-Ds) and.
Absorbance-based cell quantitation assays. MTT, XTT, and resazurin are reduced by active mitochondria to yield colored products, and thus are useful for assaying cell viability and quantitating cell number.
