Flavonoid and isoflavonoid glycosides are common dietary phenolics which may be absorbed from the small intestine of humans. The ability of cell-free extracts from human small intestine and liver to deglycosylate various (iso)flavonoid glycosides was investigated. Quercetin 4'-glucoside, naringenin 7-glucoside, apigenin 7-glucoside, genistein 7-glucoside(More)
Environmental mycobacteria are of increasing concern in terms of the diseases they cause in both humans and animals. Although they are considered to be ubiquitous in aquatic environments, few studies have examined their ecology, and no ecological studies of coastal marine systems have been conducted. This study uses indirect gradient analysis to illustrate(More)
Mycobacterium shottsii and M. pseudoshottsii are recently described mycobacteria commonly isolated from Chesapeake Bay striped bass Morone saxatilis. However, their distribution in striped bass outside of the Chesapeake region and their ability to infect alternative hosts have not been described. Mycobacteria identified as M. shottsii (based on fatty acid(More)
Mycobacteriosis is a chronic bacterial disease causing an ongoing epizootic in striped bass Morone saxatilis in Chesapeake Bay, U.S.A. Prevalence of disease is high in pre-migratory fish, and multiple species of Mycobacterium spp. have been isolated. However, prevalence of mycobacteriosis in the coastal migratory population is unknown and is of concern to(More)
Challenge studies with Mycobacterium marinum clearly demonstrate that a poor diet affects the progression and severity of mycobacteriosis in striped bass Morone saxatilis. Fish (n = 512 total, wt = 65 +/- 15 g) were inoculated intraperitoneally with 10(4) colony-forming units (CFU) g(-1) body weigth (BW) or a physiological saline solution (controls) and(More)
A retrospective analysis of archived tissue blocks has revealed that mycobacteriosis was apparent in Chesapeake Bay striped bass as early as 1984. Of 37 cases available from the years 1975 to 1985, 2 fish were found positive based on histopathology and genus-specific PCR. Multi-gene sequencing places the bacteria from the 2 positive cases (1984 and 1985)(More)
Striped bass Morone saxatilis were studied in order to characterize their immune responses over the short term following challenge with Mycobacterium marinum. The expression of immunity-related genes (IL-1beta, TNF-alpha, Nramp and TGF-beta) quickly increased following infection with M. marinum, but these genes were subsequently down-regulated despite the(More)
This article combines the researched sciences of logic, philosophy, and medicine to develop a perspective on safety belt laws. The positions of advocacy and opposition are examined primarily by a nonphysician in a reasonably unbiased manner. The result is an enhanced awareness of principles not commonly employed by physicians which may be useful to the(More)
