The topographical evolution of the films under swift heavy ion (SHI) bombardment
was probed using atomic force microscope S3I-201 in vitro and it was noticed that surface roughening was taking place with ion beam irradiation. Magnetic measurements using a vibrating sample magnetometer showed that the coercivity of the films increases with an increase in the ion fluence. The observed coercivity changes are correlated with topographical evolution of the films under SHI irradiation. The ability to modify the magnetic properties via SHI irradiation could be utilized for applications in thin film magnetism.”
“Objectives. Many patients develop dental treatment-related symptomatic trigeminal neuralgia. However, the effectiveness of pulsed
radiofrequency (PRF) treatment and conventional radiofrequency thermocoagulation (RFTC) for treatment of this disorder has not been determined. This retrospective study was conducted to compare the effectiveness and complications of PRF and RFTC in these patients. TH-302 manufacturer Methods. Fifty-four patients who experienced the onset of symptomatic trigeminal neuralgia after a dental treatment were managed by PRF or RFTC. Data were collected by reviewing their medical records and conducting a questionnaire. Patients’ characteristics, the dental procedures that caused the trigeminal neuralgia, the baseline and posttreatment pain intensities, duration of pain relief, complications, and satisfactions to the treatment were evaluated. Results. Pain intensities were lower at 1 week (3.0/10 vs 6.4/10), at 1 month (2.5/10 vs 5.9/10), 3 months (2.6/10 vs 5.5/10), 6 months (3.1/10 vs 7.1/10) and 1 year (4.8/10 vs 7.2/10) in the RFTC group (28 patients) than in the PRF group (26 patients) (P<0.05). The duration of pain relief without medication in the RFTC group (10.8 months) was longer than that in the PRF group (0 months). The incidence of selleck compound complications in the RFTC group (46.4%) was higher than that in the PRF group (3.8%) (P<0.05). The RFTC group reported
higher satisfaction ratings (3.86/5) than the PRF group (2.19/5) (P<0.05). Conclusions. Although the RFTC group had more complications than the PRF group, most were minor and transient, and the patient satisfaction rate with RFTC was very high. Therefore, RFTC is an effective tool for the treatment of dental procedure-induced trigeminal neuralgia.”
“P>Objectives:
To test the hypothesis that high-dose dexmedetomidine can be successfully used for pediatric magnetic resonance imaging (MRI) sedation without significant hemodynamic compromise.
Background:
The dexmedetomidine dose required to achieve optimal sedation is often higher than its recommended dose. High doses of dexmedetomidine can lead to significant hemodynamic side effects.
Methods:
Dexmedetomidine use for pediatric MRI over a 1-year period was retrospectively reviewed.
