Good functional outcome following bilateral external capsule hemorrhage mimicking bilateral basal ganglia hemorrhage in a coma patient.

Simultaneous spontaneous bilateral external capsule hemorrhage is a rare clinical entity with extremely poor outcome. However, knowledge on the effective management of this fatal disease is limited. Herein,we described a case of a 42-year-old man with acute coma and quadriplegia as well as respiratory failure related to the disease. The patient underwent minimally invasive surgery plus local thrombolysis. Consequently, he recovered with satisfactory neurological function recovery on the 180th day of follow-up.

Degradation of methyl orange through synergistic effect of zirconia nanotubes and ultrasonic wave.

Zirconia nanotubes with a length of 25 µm, inner diameter of 80 nm, and wall thickness of 35 nm were prepared by anodization method in mixture of formamide and glycerol (volume ratio = 1:1) containing 1 wt% NH(4)F and 1 wt% H(2)O. Experiments showed that zirconia nanotubes and ultrasonic wave had synergistic degradation effect for methyl orange and the efficiency of ultrasonic wave increased by more than 7 times. The decolorization percentage was influenced by pH value of the solution. Methyl orange was easy to be degraded in acidic solution. The decolorization percentage of methyl orange reached 97.6% when degraded for 8h in 20mg/L methyl orange solution with optimal pH value 2. The reason of synergistic degradation effect for methyl orange might be that adsorption of methyl orange onto zirconia nanotubes resulted in the easy degradation of the methyl orange through ultrasonic wave.
