Plant MADS-box genes can be divided into 11 groups. Genetic analysis has revealed that most of them function in floweringtime control, reproductive organ development, and vegetative growth. Here, we elucidated the role of OsMADS26, a member of the AGL12 group. Transcript levels of OsMADS26 were increased in an age-dependent manner in the shoots and roots. Transgenic plants of both rice (Oryza sativa) and Arabidopsis (Arabidopsis thaliana) overexpressing this gene manifested phenotypes related to stress responses, such as chlorosis, cell death, pigment accumulation, and defective root/shoot growth. In addition, apical hook development was significantly suppressed in Arabidopsis. Plants transformed with the OsMADS26-GR (glucocorticoid receptor) fusion construct displayed those stress-related phenotypes when treated with dexamethasone. Microarray analyses using this inducible system showed that biosynthesis genes for jasmonate, ethylene, and reactive oxygen species, as well as putative downstream targets involved in the stress-related process, were up-regulated in OsMADS26-overexpressing plants. These results suggest that OsMADS26 induces multiple responses that are related to various stresses.

BackgroundWe aimed to investigate the role of surgical excision in treating granulomatous lobular mastitis.MethodsWe performed a retrospective chart review of patients with granulomatous lobular mastitis treated from March 2008 to March 2014. We analyzed clinical features and therapeutic modalities and compared the patient outcomes based on treatment.ResultsDuring the study period, a total of 34 patients were diagnosed with granulomatous lobular mastitis and treated. Initial treatments included wide excision (18), oral steroids after incision and drainage (14), and antibiotic therapy (2). The patients receiving only antibiotic therapy showed no improvement after 1 month and wide excision was then performed. Wide excision resulted in nine case of delayed wound healing with fistula. These patients were treated with oral steroids for 1.5-5 months, with subsequent improvement. Overall, 11 out of 20 patients who had underwent wide excision showed improvement without additional treatment. Fourteen patients who had initially received oral steroids for 1 to 6 months (average, 2.8 months) after incision and drainage showed complete remission. During the median follow-up period with 45.5 months (range, 22–98 months), six patients (17.6%) experienced recurrence. Wide excision group experienced recurrence in five (25%) and steroid and drainage group experienced recurrence in one (7.1%). All six recurrences responded to additional steroid therapy for average 3.5 months. Most wide excision group left extensive breast scarring with deformation that was not in steroid and drainage group.ConclusionsWide excision resulted high recurrence than steroid and drainage group and left extensive scarring. Steroid therapy with or without abscess drainage may be the first choice of treatment for majority cases with granulomatous lobular mastitis.

BackgroundThe transversus abdominis plane block is recently described peripheral block to providing analgesia to the anterior abdominal wall. The goal of this study is to evaluate the analgesic efficacy of the ultrasound-guided transversus abdominis plane block (US-TAP block) in patients undergoing gynecologic surgery via a transverse lower abdominal skin incision.MethodsThirty-two patients undergoing gynecologic surgery were randomized to undergo standard care such as PCA, or to receive additional US-TAP block with standard care. After general anesthesia induction, a bilateral US-TAP block was performed using 0.375% ropivacaine 20 ml on each side. Postoperative demand of rescue analgesics in PACU and ward were recorded. Each patient was assessed postoperatively by a blinded investigator in the postanesthesia care unit (PACU) and at 2, 6, 10, 24, 48 hr postoperatively to investigate pain, drowsiness, nausea and itch.ResultsThe US-TAP block reduced pain intensity compared to standard care in the PACU (5.2 ± 3.1 vs 8.4 ± 1.3) and at 2, 24 postoperative hours (3.0 ± 2.4 vs 5.2 ± 2.4, 0.9 ± 1.5 vs 2.2 ± 1.9). Fentanyl requirements in PACU was reduced (20.3 ± 20.9 vs 62.5 ± 35.4 µg, P < 0.05). In ward, pethidine requirements was reduced (21.9 ± 28.7 vs 56.3 ± 34.8 mg, P < 0.05).ConclusionsThe US-TAP block with standard care provide more effective analgesia after gynecologic surgery via a transverse lower abdominal skin incision.

BackgroundAs the number of elder patients grows, spinal anesthesia for such patients are increasing significantly. Any effort is needed to use the least anesthetic drug for maintaining the anesthesia while avoiding hazards of cardio-pulmonary complications.MethodsAmerican Society of Anesthesiologists physical status classification I and II, Forty five elderly patients (≥ 60 years) who received transurethral resection of the prostate or transurethral resection of the bladder tumor were allocated randomly into three treatment groups. The DMT 0.5 group was designed as with dexmedetomidine 0.5 µg/kg while the DMT 1.0 group has a 1 µg/kg intravenous injection over 10 min before anesthetic induction. The Control group was designed to get a normal saline. Each group was compared regarding the maximum sensory block level, extension of anesthesia, degree of motor block, level of sedation, VAS score and complications.ResultsThere were no significant differences among the 3 treatment groups regarding the maximum level of sensory block and motor block. However, the duration of sensory block was significantly longer in DMT 1.0 group than in the control group (P = 0.045). Both DMT 1.0 group (median = 3, range = 2-6) and DMT 0.5 group (median = 3, range = 1-6) showed a mean value of 3-4 Ramsay sedation score, which resulted in more excessive sedation and significantly greater incidence of bradycardia compared to the control group. No complications such as hypotension, nausea, tremor, and hypoxia were found during this investigation.ConclusionsIn elder patients, the DMT 1.0 group is effective in duration of sensory block and is superior in the aspect of prolonged duration of sensory block compared to the DMT 0.5 group.

PurposeThere have been recent studies of the 18F-fluorodeoxyglucose positron emission tomography and computed tomography (18F-FDG PET/CT) in the staging, detection, and follow-up of the breast cancer occurrence and recurrence. There was controversy concerning the use of 18F-FDG PET/CT for staging primary breast cancer. In this study, we investigated the potential effects of 18F-FDG PET/CT in the initial assessment of patients with primary breast cancer.MethodsFrom January 2008 to December 2009, 154 consecutive biopsy-proven invasive breast cancer patients were enrolled in this study. Patients underwent conventional imaging studies including mammography, breast ultrasonography (USG), and magnetic resonance imaging for local assessment, and plain chest X-ray, liver USG, and bone scan to rule out distant metastasis. All 154 patients underwent 18F-FDG PET/CT in the initial assessment.Results18F-FDG PET/CT did not detect primary breast lesions in 16 patients with a sensitivity of 89.6% and detected only 5 multiple lesions (12.5%) out of 40 cases. Histologically confirmed axillary lymph node (LN) metastases were in 51 patients, and the sensitivity and specificity of 18F-FDG PET/CT to detect metastatic axilla were 37.3% and 95.8%, respectively; whereas the corresponding estimates of USG were 41.2% and 93.7%, respectively. Eleven extra-axillary LN metastases were found in eight patients, and seven lesions were detected by 18F-FDG PET/CT only. The sensitivity and specificity of 18F-FDG PET/CT in detecting distant metastasis were 100% and 96.4%, respectively; whereas the sensitivity and specificity of the conventional imaging were 61.5% and 99.2%, respectively.Conclusion18F-FDG PET/CT cannot be recommended as a primary diagnostic procedure in breast cancer, but it has the potential to be used as an additional imaging tool for the detection of axillary metastasis, distant metastasis, and extra-axillary LN metastasis. 18F-FDG PET/CT cannot solely replace the conventional diagnostic procedure in primary breast cancer. The best approach may be the combination of different imaging modalities.
