Given the link between our addiction to driving and driving fast, suburban lifestyles, and scientifically proven air-quality damaging, high-emission cars, cities of all sizes in this country and their environmentally concerned citizens are now encouraging the re-creation of easy-to-use public transportation, driving slower, increased ride sharing, safe human-powered and appropriate electric-powered bicycle lanes, walking paths and trails, and alternative fuels to address public and planetary health, as well as the ever-growing obesity pandemic.

Mucins are glycoproteins expressed by epithelial tissues of mucosal surfaces. Mucins are classified as either secretory or membrane spanning, and the ocular epithelium contain both types. Since the mid-1990s, a large number of mucin (MUC) genes have been identified: MUC1, MUC2, MUC4, MUC5A, MUC5B, MUC7MUC13, MUC15, MUC16 and MUC17.
