Cellular toxicity, pharmacokinetics, and the in vitro and in vivo stability of the SO3*- spin adduct of the spin trap, 5-diethoxyphosphoryl-5-methyl-1-pyrroline-n-oxide (DEPMPO), was investigated, and the results were compared with those of the widely used spin trap 5,5-dimethyl-1-pyrroline-N-oxide (DMPO). Similar to DMPO, DEPMPO was quickly taken up (<15(More)
Little information is available regarding the effect of oral intervention on the outcome of hematopoietic stem cell transplantation (HSCT). We retrospectively analyzed the incidence of oral mucositis after allogeneic HSCT with or without oral intervention among 96 consecutive patients in our hospital between January 1988 and March 2006. We combined two oral(More)
In vivo spin trapping is potentially a very useful tool to investigate the role of free radicals in physiologic processes and disease development. Unfortunately, knowledge on the stability and distribution of spin traps in living systems is limited. Therefore, in our study, we selected 11 acyclic and cyclic nitrone spin traps with diverse properties to(More)
We describe a technique that utilizes electron paramagnetic resonance (EPR) to measure NO(*) and pO(2) directly, and non-invasively, from tissue in vivo. Diethyldithiocarbamate (DETC) was injected with iron so as to complex with NO(*) in the tissue. Gloxy (an oxygen-sensitive, paramagnetic material) was also implanted into the tissue of interest (brain or(More)
Carbon based paramagnetic materials are frequently used for EPR oximetry, especially in vivo, but the EPR spectra of these materials often have more than one paramagnetic center and/or relatively low signal intensity. To determine whether the multi-components of carbon based materials could be separated and enriched in the active component, we used density(More)
The management of bisphosphonate-related osteonecrosis of the jaw (BRONJ) is still difficult in many cases that do not respond to conservative treatments. We report a case of BRONJ treated by adjunctive teriparatide therapy for 6 months with monitoring of bone turnover markers (at baseline, at 1, 3, and 6 months of treatment, and after 9 months off therapy)(More)
UNLABELLED The adequacy of cerebral tissue oxygenation (PtO(2)) is a central therapeutic end point in critically ill and anesthetized patients. Clinically, PtO(2) is currently measured indirectly, based on measurements of cerebrovascular oxygenation using near infrared spectroscopy and experimentally, using positron emission tomographic scanning. Recent(More)
AIMS The effects of temperature and concentration of dissolved CO(2) on the inactivation of Saccharomyces cerevisiae were investigated using a plug-flow system. METHODS AND RESULTS Several combinations of pressure (4, 6, 8, 10 mega-Pa (MPa)) and temperature (30, 34, 36, 38 degrees C) were used. The D-values obtained were 0.14 min at 8 MPa and 38 degrees(More)
PURPOSE Elimination of methicillin-resistant Staphylococcus aureus (MRSA) is of critical importance in oral and maxillofacial surgery because control is very difficult once infection of an oral tumor or oral wound with MRSA is established. PATIENTS AND METHODS We retrospectively investigated the risk factors for acquiring MRSA in 518 patients with oral(More)
