The purpose of this study was to analyze biochemical measures of oxidative stress and assess their relationship to insulin requirements early in type 1 diabetes. Thirty-seven patients enrolled in a 3-yr longitudinal study of the effects of oxidative stress on the early natural history of this disorder. We measured plasma nitrite and nitrate (collectively(More)
The inhalation of silica has been shown to produce a dramatic inflammatory and toxic response within the lungs of humans and laboratory animals. A variety of cellular and biochemical parameters are used to assess the silica-induced lung injury. The purpose of this paper is to introduce the use of luminol-dependent chemiluminescence as a new method to study(More)
In vitro evidence indicates that tetrandrine (TT) can potentiate the action of chloroquine 40-fold against choloquine-resistant Plasmodium falciparum. The key question emanating from that study is “would tetrandine and chloroquine be highly effective in a live Aotus monkey model with chloroquine-resistant parasites”. This study was designed to closely mimic(More)
BACKGROUND Anaesthetics suppress the formation of lasting memories at concentrations that do not suppress perception, but it is unclear which elements of the complex cascade leading from a conscious experience to a lasting memory trace are disrupted. Experiments in conscious humans suggest that subhypnotic concentrations of anaesthetics impair consolidation(More)
Since oxidative/nitrosative stress cause diabetes, can we prevent this chemistry generating the disease? Streptozotocin causes diabetes by entering the pancreatic beta cell generating excessive nitric oxide which reacts with oxygen creating a toxin possibly peroxynitrite, dinitrogen trioxide, dinitrogen tetraoxide and so forth. The toxic compounds damage(More)
The objective of these studies was to determine whether inosine, a precursor of the antioxidant uric acid, can ameliorate hemin-induced oxidative stress. Dietary inclusion of inosine was begun either before or after hemin-induced oxidative stress. Broilers (4 weeks) were divided into four treatment groups (Control, Hemin, Inosine, Hemin/Inosine). Throughout(More)
Viruses are obligate intracellular parasites that use many of the host cell's biochemical mechanisms and products to sustain their viability. A mature virus (virion) can exist outside a host cell and still retain its infective properties. However, to reproduce, the virus must enter the host cell, take over the host cell's mechanisms for nucleic acid and(More)
