ABSTRACT We report a rare case of emphysematous cystitis in a 66-year-old woman with a history of diabetes mellitus. The predisposition of diabetes mellitus and infection of gas-forming bacteria is considered to precede the manifestation of emphysematous cystitis. The present recommended diagnosis test is computed tomography, which have definite value in the evaluation of gas accumulation in bladder wall, or an air-fluid level in bladder.

An understanding of the relationship of geographically different soybean gene pools, based on selectively neutral DNA markers would be useful for the selection of divergent parental cultivars for use in breeding. We assessed the relationships of 194 Chinese, 59 Japanese, and 19 Brazilian soybean cultivars (n = 272) using 12 simple sequence repeat (SSR) markers. Quantification Theory III and clustering analyses showed that the Chinese and Japanese cultivars were genetically quite distant to each other but not independent, while Brazilian cultivars were distantly related to the cultivars from the other two countries and formed a cluster that was distant from the other two gene pool clusters. Our results indicated that the Brazilian soybean gene pool is different from the Chinese and Japanese pool. Exchanges of these gene pools might be useful to increase the genetic variability in soybean breeding.
