Objective: The malignant transformation (MT) of ovarian mature cystic teratoma (MCT)to squamous cell carcinoma (SCC) is very rare. This study analyzed cases from multiplemedical centers in Taiwan to investigate the clinicopathologic characteristics, treatment, andprognostic factors of this disease and reviewed related literature. Methods: Pathological reports of 16,001 patients with primary ovarian cancer who weretreated at Taiwan medical centers from 1990 to 2011 were reviewed. In total, 52 patients withMT of MCT to SCC were identified. Results: Among all ovarian MCTs, the incidence of MT to SCC is 0.2%. The median age ofpatients was 52 years (range, 29–89 years), and the mean tumor size was 10.5 cm (range, 1–40cm). We analyzed the patients in our study and those in the literature and determined thatearly identification and complete surgical resection of the tumor are essential for long-termsurvival. In addition, adjuvant chemotherapy or concurrent chemoradiotherapy can be usedto treat this malignancy. Old age, large tumor size (≥15.0 cm), and solid components in MCTsare suitable indicators predicting the risk of MT of MCT to SCC. Conclusion: Similar to general epithelial ovarian cancers, the early detection of MT of MCTto SCC is critical to long-term survival. Therefore, older patients with a large tumor or those with a tumor containing a solid component in a clinically diagnosed MCT should beevaluated to exclude potential MT to SCC.

With the completion of genomic sequencing of rice, rice has been firmly established as a model organism for both basic and applied research. The next challenge is to uncover the functions of genes predicted by sequence analysis. Considering the amount of effort and the diversity of disciplines required for functional analyses, extensive international collaboration is needed for this next goal. The aims of this review are to summarize the current status of rice mutant resources, key tools for functional analysis of genes, and our perspectives on how to accelerate rice gene discovery through collaboration.

NbN films were prepared by radio frequency reactive magnetron sputtering and then employed as diffusion barriers between Cu and Si. The microstructure of the NbN films was an assembly of very small columnar crystallites with a cubic structure. To investigate the properties as diffusion barriers, we performed metallurgical reactions of Cu/NbN0.8/Si, Cu/Nb/Si and Cu/TaN0.7/Si for comparisons. The sheet resistance increased dramatically after annealing above 750°C for Cu/NbN0.80/Si, and above 500°C for both Cu/Nb/Si and Cu/TaN0.7/Si. The interfaces were deteriorated seriously and formation of Cu3Si was observed when the sheet resistance was significantly increased. The diffusion coefficient of Cu in NbN barrier films was estimated by using the change of resistance (ΔRs/Rs %). Compared with TaN0.7, NbN0.8 films possess larger grain size and lower Cu diffusion coefficient. Our results suggest that the NbN film can be used as a diffusion barrier for Cu metallization as compared to the well-known TaN film.

Purpose: Recently the incidence of severe hyponatremia is increasing in old patients but there is no report about clinical findings of old patients with hyponatremia. We evaluated the cause and clinical manifestations of severe hyponatremia in old patients who had been admitted via emergency room. Methods: We retrospectively reviewed clinical records of the hyponatremic patients who had been admitted from 2000 to 2007. We enrolled 53 patients (Age>60 years, Na<125mEq/L) without severe liver cirrhosis, heart failure or chronic kidney disease. We analyzed data to evaluate the differences of clinical manifestations according to the presence of symptoms, taking diuretics, urine sodium concentrations and the degree of hyponatremia. Results: Mean serum sodium concentration was 111.4±6.9mEq/L and urine sodium concentration was 68.7±43.8mEq/L. There was no difference in serum sodium concentration according to age. Twenty-nine (54.7%) patients had nausea and vomiting and 19 patients (35.8%) had neurologic symptoms. Patients with neurologic symptoms showed lower serum and urine sodium concentration than patients without neurologic symptoms. The main causes of severe hyponatremia were poor oral intake (79.2%), diuretics use (37.7%) and recent operation (15.1%). The mean sodium concentration of the fluid administered to achieve 125mEq/L of serum sodium level was 336.5±160.6mEq/L. Conclusion: The urinary sodium loss, e.g., diuretics abuse, may be the main cause of severe hyponatremia in elderly patients over 60 years. In elderly patients, diuretics should be carefully administered with frequent electrolyte monitoring.
