Recently, several digital watermarking techniques have been proposed for hiding data in the frequency domain of audio files in order to protect their copyrights. In general, there is a tradeoff between the quality of watermarked audio and the tolerance of watermarks to signal processing methods, such as compression. In previous research, we simultaneously improved the performance of both by developing a multipurpose optimization problem for deciding the positions of watermarks in the frequency domain of audio data and obtaining a near-optimum solution to the problem. This solution was obtained using a wavelet transform and a genetic algorithm. However, obtaining the near-optimum solution was very time consuming. To overcome this issue essentially, we have developed an authentication method for digital audio using a discrete wavelet transform. In contrast to digital watermarking, no additional information is inserted into the original audio by the proposed method, and the audio is authenticated using features extracted by the wavelet transform and characteristic coding in the proposed method. Accordingly, one can always use copyright-protected original audio. The experimental results show that the method has high tolerance of authentication to all types of MP3, AAC, and WMA compression. In addition, the processing time of the method is acceptable for every-day use.

A 73-year old man presented with abdominal pain. A tumor with central ulceration was observed in the ileum using double-balloon enteroscopy. Histological findings of the biopsy specimens were consistent with malignant lymphoma. Double-balloon enteroscopy confirmed the diagnosis of a malignant lymphoma tumor which was surgically resected. The patient is still in complete remission now.

Spontaneous venous rupture overlying a uterine fibroid is a rare cause of hemoperitoneum. A 38-year-old woman presented to the emergency department with acute onset of abdominal pain. The ultrasound revealed multiple fibroids and free fluid in the peritoneum. There was a significant drop of the hemoglobin and hematocrit. The patient underwent emergent exploratory laparoscopy. A subserosal uterine leiomyoma was found, with a bleeding vein on its basis and massive hemoperitoneum. Laparoscopic myomectomy was successfully performed with local injection of vasopressin and intraoperative autologous blood transfusion. This case suggests that spontaneous intraperitoneal haemorrhage associated with uterine fibroids, although rare, should be considered in women with hypovolemic shock and a pelvic mass.

Calcium channel blocker-induced gingival overgrowth (CCB-GO) is increasing in elderly patients who have been prescribed medication for hypertension for years. The purpose of the present study was to analyze the comprehensive protein expression levels of candidate biomarkers in gingival crevicular fluid (GCF) from CCB-GO patients. Eleven GO patients (10 males and one female, mean ± SD: age: 64.4 ± 14.0 years) who had been systemically prescribed CCBs, either amlodipine or nifedipine, for hypertension for at least 12 months were recruited. Before (baseline) and 4 weeks after initial periodontal treatments, subgingival plaque and GCF samples were taken from two sites per patient: sites affected by CCB-GO and chronic periodontitis. Measurement of clinical parameters and quantitative analysis of periodontopathic bacteria using real-time PCR were performed. Biomarkers/cytokines in GCF were examined using multiplex bead immunoassays. The Mann-Whitney U test was used to compare the collected data between groups. The correlations between pairs of biomarkers were assessed using the Spearman correlation relationship. Levels of two of the 14 biomarkers, interleukin (IL)-1β and transforming growth factor (TGF)- β, were significantly decreased in CCB-GO sites after initial periodontal therapy. The intragroup comparison at baseline showed that counts of Treponema denticola in the GO group were significantly higher than those in the chronic periodontitis group (P β and TGF-β in CCB-GO patients. These factors are involved in initiation and progression of GO as well as periodontitis.
