Despite a nationwide survey experiences with SNS as a treatment for fecal incontinence following rectal resection is still limited. Our observations show an improvement of the continence function following SNS. However, the promising results of our series as well as others need further research and more clinical data by a larger number of patients in a prospective trial.
Because titanium is increasingly used in microelectronic devices, a method of isotope dilution mass spectroscopy (IDMS) has been developed for the reliable determination of traces of relevant heavy metals (U, Th, Cu, Pb, Cd, Cr, Ni, and Fe) in high-purity titanium primary materials. The measurements of isotope ratios were carried out with a thermal ionization quadrupole mass spectrometer using positive thermal ions formed by a singleor double-filament ion source, except for thorium where an inductively coupled plasma mass spectrometer was applied. Different separation techniques (ion exchange chromatography, extraction, electrolytic deposition, co-precipitation) were used for the trace/matrix separation and the element-specific isolation of the trace elements to be determined. The detection limits obtained were (in ng/g
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
