Spontaneous and collision-induced dissociation processes of C02+ ions, formed by electron impact, have been studied in a double-focusing mass spectrometer using techniques of ion kinetic energy spectroscopy. The predissociation process, responsible for unimolecular dissociation of C02+ on the...
Experimental values of kinetic energy release T, for predissociation processes of diatomic di‐cations N2+ 2, O2+ 2, and NO2 + have been obtained using techniques of ion‐kinetic‐energy spectroscopy on a double‐focusing mass spectrometer. Both unimolecular and collision‐induced processes were...
The B subunit of cholera toxin has been covalently attached to the surface of Uposomes made from a mixture of phosphatidylethanolamine, phosphati- dylcholine and cholesterol. Adenylate cydase inhibitors and chloride conduc- tance inhibitors were encapsulated within the liposomes. These...
A single barn was sampled throughout a turkey growth cycle to investigate the size and distribution of airborne particles and to identify individual dust sources. Fecal material was found to be the main constituent of airborne dust in turkey barns. The aerodynamic properties of airborne dust and...
Transrectal real-time ultrasonography has proved to be a rapid and reliable technique for studying reproductive functions in cattle. Through ultrasonography it is now established that follicular growth occurs in wave-like patterns during each estrous cycle. It has been shown that follicular...
Four environmental chambers housing either 75 (5.5 birds/m\") or 37 turkeys (2.8 birds/m ) were used to study the impact of stocking density on air quality, bird health, and performance under similar per bird ventilation rates (3 L/s per bird). Stocking density had little effect on air quality or...
Spectroscopic characterization of recombinant dihydrolipoamide dehydrogenase and its site-directed mutantsDownload
In this paper, we report the overexpression and single-step purification of recombinant wild-type and site-directed mutants of human dihydrolipoamide dehydrogenase in Escherichia coli and detailed spectroscopic studies aimed at understanding the catalytic mechanism of this enzyme. One mutation...
Separation and quantitation of apolipoprotein B48 and other apolipoproteins by dynamic sieving capillary electrophoresisDownload
Apolipoprotein-B-48 is a structural protein exclusively associated with post-prandial lipoproteins (chylomicrons). Apolipoprotein B-48 would be a useful marker to monitor the kinetics of chylomicrons in vivo, however, its quantitation is limited because of a low concentration in plasma and lack...
Dietary oxysterols are incorporated in plasma triglyceride rich lipoproteins, increase their susceptibility to oxidation and increase aortic cholesterol concentration of rabbitsDownload
Early fatty streaks and advanced lesions are characterized by the deposition of cholesterol and cholesterol oxidation products (oxysterols). Oxysterols have been shown to be cytotoxic and pro-atherogenic compared to cholesterol and are found in cholesterol-rich processed foods. The consumption of...
High-fructose feeding of streptozotocin-diabetic rats is associated with increased cataract formation and increased oxidative stress in the kidneyDownload
We examined the effects of high-fructose (FR) feeding on the development of diabetic complications in the lens and the kidney of streptozotocin (STZ)-diabetic rats. Male Wistar Furth rats were treated with one of two doses of STZ (HIGH STZ, 55 mg/kg body weight; MOD STZ, 35 mg/kg body weight) or...
