Saprolegniosis (Chapter 29) is a widespread, familiar disease (or a complex of diseases, perhaps) seemingly accorded only a lowly place in the economics of fisheries. Save for occasional outbreaks, it is a malady of endemic proportions with which the freshwater fisheries industries coexist. Not so the crayfish plague (Krebspest, Kräftpesten), caused by Aphanomyces astaci (Schikora, 1906). This ...

For many people, cancer is the most feared health diagnosis imaginable and brings about immediate thoughts of death. Even cancer healthcare providers have been shown to exhibit a sense of hopelessness and negative attitudes toward a cancer diagnosis. Yet, overall cancer survival rates have been increasing over the past 30 years, suggesting that a diagnosis of cancer should not necessarily be as...

Given a finite collection S of geometric objects such as hyperplanes or spheres in R , the arrangement A(S) is the decomposition of R into connected open cells of dimensions 0, 1, . . . , d induced by S. Besides being interesting in their own right, arrangements of hyperplanes have served as a unifying structure for many problems in discrete and computational geometry. With the recent advances ...

Metastatic prostate cancer is a leading cause of cancer-related death in men worldwide. We have recently discovered that IL-30 shapes the microenvironment of prostate cancer and tumor-draining lymph nodes to favor tumor progression. IL-30 supports tumor growth in vitro, and IL-30 expression in prostate cancer patients is associated with high tumor grade and metastatic stage of disease. Thus, IL...
