Fruit with light hrown spots that enlarge and darken. Cause Black rot. Common east of the Rockies, especially in hot, humid weather, black rot causes fruit to shrivel into hard, black shriveled berries (known as mummies) that remain on the cluster. Overwintering mummies and infected canes or shoots carry the disease from one growing season to the next. For control, remove and destroy all mummies. For persistent infection, apply copper sprays. Cultivars moderately resistant to black rot include Beta , Campbell s Early , Cascade , Chancellor , De Chaunac , Delaware , Elvira , Fredonia , Hunt , Ives , James , Scuppemong , Sheridan , and Worden . See page 109 for an illustration of this disease. 

It should be noted that ha might range from a constant zero-order rate constant to complex functions responsible for irregular biorhythmic baseline profiles. Appreciation of these fundamental principles derives from the fact that both drugs and diseases alter normal biological cascades responsible for controlling the homeostasis of physiological systems. 

Systems biology is an area that academics and pharmaceutical companies are rapidly embracing. Systems biology seeks to understand the complex relationships between signaling cascades, transcriptional control, and disease-relevant phenotypes at the cellular and organism levels. Usually these interrelationships are presented as a computational model. For example, a model might be built of the insulin-signaling pathway as a means to better treat diabetes. 

Hormones are molecules organisms use to convey information between cells. When target cells are distant from the hormone-producing cell, such molecules are called endocrine hormones. To ensure proper control of metabolism, the synthesis and secretion of many mammalian hormones are regulated by a complex cascade mechanism ultimately controlled by the central nervous system. In addition, a negative feedback mechanism precisely controls various hormone syntheses. A variety of diseases are caused by either overproduction or underproduction of a specific hormone or by the insensitivity of target cells.
