“Light-induced domain reversals of Mg-doped,
Zr-doped, and nominally pure LiNbO3 crystals were investigated with focused 514.5 nm laser beams. It was found the light-reduced values of electric field for domain reversal are almost the same, about 3 kV/mm. Inverted domains always first nucleate on the -c surface within the illuminated region but appear at the edge of the spot on the +c surface. The light-induced inverted domains are hard to be reversed by application of a reverse electric field or by heating to temperatures as high as 600 degrees C. According to these experimental results, we present a qualitative model on the light-induced domain reversal process in LiNbO3.”
“Background: Vibrio vulnificus can cause a rapidly progressive fatal soft-tissue infection. Staphylococcus aureus is the most SHP099 cell line common cause of, skin and soft-tissue infections reported worldwide, and, in particular, methicillin-resistant Staphylococcus aureus has emerged as the most
common isolate in emergency departments. The purposes of the present study were to compare the specific characteristics of Vibrio vulnificus and Staphylococcus aureus infections and to compare the clinical outcomes of Vibrio vulnificus, methicillin-resistant Staphylococcus aureus, and methicillin-sensitive Staphylococcus aureus necrotizing infections.
Methods: One hundred and fifteen patients with necrotizing fasciitis caused by Vibrio vulnificus (sixty patients) or Staphylococcus aureus (fifty-five INCB028050 chemical structure patients) were retrospectively reviewed over a six-year period. Differences in mortality, patient characteristics, clinical presentations, laboratory
data, and hospital course were compared between the Vibrio vulnificus and Staphylococcus aureus groups.
Results: Nineteen patients (including eleven in the Vibrio vulnificus group and eight in the Staphylococcus aureus group) died, resulting in a mortality https://www.selleckchem.com/products/gsk1838705a.html rate of 16.5%. We found significant differences between the two groups with regard to hypotension, fever, the interval between contact and admission, the interval between the diagnosis of necrotizing fasciitis and the first operation, and admission to the intensive care unit. The patients in the Vibrio vulnificus group had significantly lower total white blood-cell counts, higher banded white blood-cell counts, and lower platelet counts as compared with those in the Staphylococcus aureus group. The proportion of patients who were hypotensive (as indicated by a systolic blood pressure of <= 90 mm Hg) was significantly greater in the methicillin-resistant Staphylococcus aureus subgroup than in the methicillin-sensitive Staphylococcus aureus subgroup.
