The influence of salts (KCl, NaCl, CaCl(2), and MgCl(2)) on bicelles (bilayered micelles) made of dimyristoylphosphatidylcholine (DMPC, molar fraction X = 78%) and dicaproylphosphatidylcholine (DCPC) was investigated by solid-state (31)P- and (2)H NMR as well as by freeze-fracture electron microscopy. Sizes were determined from (2)H- and (31)P NMR on the(More)
BACKGROUND More than 100 years after its inception the chiropractic profession has failed to define itself in a way that is understandable, credible and scientifically coherent. This failure has prevented the profession from establishing its cultural authority over any specific domain of health care. OBJECTIVE To present a model for the chiropractic(More)
OBJECTIVE The aim of this study was to measure the effects of a managed chiropractic benefit on the rates of specific diagnostic and therapeutic procedures for the treatment of back pain and neck pain. DESIGN This study is a retrospective analysis of claims data from a managed-care health plan over a 4-year period. The use rates of advanced imaging,(More)
An analysis of claims data from a managed care health plan was performed to evaluate whether patients use chiropractic care as a substitution for medical care or in addition to medical care. Rates of neuromusculoskeletal complaints in 9e diagnostic categories were compared between groups with and without chiropractic coverage. For the 4-year study period,(More)
OBJECTIVE The aim of this study is to measure the selection effects of the inclusion of a chiropractic benefit on a managed care health plan. DESIGN An analysis of enrollment data from a managed care health plan over a 4-year period was conducted. Employers could select the managed care plan with or without a chiropractic care benefit. Comparisons of(More)
Amphiphile supramolecular assemblies result from the cooperative effects of multiple weak interactions between a large number of subcomponents. As a result, prediction of and control over the morphologies of such assemblies remains difficult to achieve. Here, we described the fine-tuning of the shape, size, and morphology transitions of twisted and helical(More)
Cationic gemini surfactants having nucleotides as counterions (called nucleo-gemini hereafter) were synthesized and their aggregation behavior at air-water surfaces as well as in bulk solutions were studied. Fluid solutions of these nucleo-gemini surfactants show transitions to hydrogels upon addition of complementary nucleoside bases or other nucleo-gemini(More)
