The oxidation of dimethyl sulfoxide (DMSO) by hydrogen peroxide in the presence of a catalytic amount of sodium tungstate (Na 2 WO 4 ) has been studied kinetically by means of iodometry of hydrogen peroxide. The reaction is first-order with respect to the substrate and the catalyst, but independent of the concentration of hydrogen peroxide which is present in excess of the catalyst. The polarographic study implies that in solutions two main kinds of peroxytungstic acids (H 2 WO 5 and H 2 WO 8 ) are formed which contain active oxygen in ratios (active oxygen):(Na 2 WO 4 ) of 1:1 and 4:1, respectively. The effect of acidity on the oxidation rate and a probable mechanism involving a rate-determining attack of peroxytungstic acids are discussed.
The ability of Listeria monocytogenes to survive or grow during Camembert cheese manufacturing, ripening and storage was examined. Two experimental methods were applied for manufacturing Camembert cheese: using Listeria-contaminated milk (1.6×104cells/ml), and using Listeria-contaminated brine (1.5×106cells/ml).Listeria counts decreased in both cases during the beginning of the ripening process; in the later stage an increase of the count occurred. The count of this organism after ripening was about the same as in the initial stage. After that the number increased gradually, and Listeria counts of 1.7×105cells/g and 1.5×108cells/g were attained after 50 days, respectively.Listeria monocytogenes survived in 18% brine at 12°C for more than 21 days.
Sternoclavicular joint dislocation (SCJD) is a rare injury; there are only two reported cases of SCJD that have occurred during judo practice. We present a case of an 18-year-old male athlete who fell while practicing judo and experienced upper left chest pain. He was diagnosed with posterior SCJD at another institute before being transferred to our hospital. Closed reduction was initially not possible using traditional methods. Reduction was eventually accomplished by clamping the proximal end of the clavicle using bone forceps and rotating it while pulling it upward. Many authors have reported that closed reduction is difficult if not performed within 48 h after SCJD injury. However, we were able to achieve closed reduction approximately 72 h after injury. We found that reduction might be easily accomplished by pulling the proximal end of the clavicle up and rotating it when other closed reduction methods are unsuccessful.
To compare the histomorphometric outcomes of biopsies collected from the antrostomy and from the alveolar crest of the maxillary sinus after a sinus-lift procedure.In 12 volunteers, sinus floor elevation was performed using collagenated corticocancellous porcine bone. Nine months after the surgery, 2 biopsies, 1 from the alveolar crest and 1 from the antrostomy, were collected for histological analysis.Biopsies from 11 patients were available for histological analyses (n = 11). At the alveolar crest sites, the percentage of mineralized bone was 40.1 ± 14.1%, of bone marrow was 40.1 ± 18.0%, and of the xenograft was 14.7 ± 15.2%. Small amounts of soft tissue were found. At the antrostomy sites, the percentages of mineralized bone, bone marrow, and xenograft were 26.0 ± 10.8%, 23.4 ± 17.0%, and 28.2 ± 15.7%, respectively. Soft tissue was represented by 19.7 ± 19.4%.Higher amounts of mineralized bone and bone marrow were found in the alveolar crest compared with the antrostomy.
