He knows how biologic systems work — and, equally important, he is an expert observer of those who observe for a living, and well acquainted with scientific doublespeak.
Some MS techniques, however, require extensive sample preparation, and interactions of biologic samples with the working surfaces of the instrument can cause performance to vary from sample to sample if not monitored carefully.
A problem when working with biologic material combined with PCR techniques is the effect of inhibitory substances; several inhibitory components in feces have been identified, such as bile salts and polysaccharides (17 ).
A biologic drug that works well when given in high volumes (because of solubility problems for example) as an intravenous infusion may lose its clinical efficacy or product quality when formulated for subcutaneous or intramuscular delivery in small volumes [27],[25].
Dr. Stone uses stem cells and other biologic techniques to work to preserve the natural biology of a joint, helping people avoid or delay an artificial joint replacement.
