OBJECTIVE To evaluate the impact of oral magnesium supplementation on risk factors for end-organ disease in patients with non-insulin-dependent diabetes mellitus (NIDDM). DESIGN A 16-week randomized, double-blind, placebo-controlled crossover trial. SETTING Outpatient center of an academic family medicine residency program. PATIENTS Twenty-eight(More)
A facile nonlithographic method for expedient fabrication of microfluidic devices of poly(dimethylsiloxane) is described. Positive-relief masters for the molds are directly printed on smooth substrates. For the formation of connecting channels and chambers inside the polymer components of the microfluidic devices, cavity-forming elements are adhered to the(More)
The purpose of this investigation is to characterize the reduced state of RNase A (r-RNase A) in terms of (i) intramolecular distances, (ii) the sequence of formation of stable loops in the initial stages of folding, and (iii) the unfolding transitions induced by GdnHCl. This is accomplished by identifying specific subdomain structures and local and(More)
Screening for pharmaceutically viable stability from measurements of thermally induced protein unfolding and short-term accelerated stress underpins much molecule design, selection, and formulation in the pharmaceutical biotechnology industry. However, the interrelationships among intrinsic protein conformational stability, thermal denaturation, and(More)
The evaluation of stability with respect to particles in prefilled syringes is complicated by the presence of silicone oil. The mobility, colloidal characteristics, and kinetic instability of silicone oil in contact with a protein formulation may be influenced in unpredictable ways by pharmaceutical variables, storage, and handling conditions. To provide(More)
Evaluating prospective protein pharmaceutical stability from accelerated screening is a critical challenge in biotherapeutic discovery and development. Measurements of protein unfolding transitions are widely employed for comparing candidate molecules and formulations; however, the interrelationships between intrinsic protein conformational stability and(More)
Bacterial endospores are some of the most resilient forms of life known to us, with their persistent survival capability resulting from a complex and effective structural organization. The outer membrane of endospores is surrounded by the densely packed endospore coat and exosporium, containing amyloid or amyloid-like proteins. In fact, it is the(More)
