Effects of sodium selenite addition on ruminal fermentation, microflora and urinary excretion of purine derivatives in Holstein dairy bulls.

Researches on sodium selenite (SS) mainly focus on production performance and rumen fermentation in ruminants, and the influence of dietary Se addition on ruminal microbial population and enzyme activity in dairy bulls is scarce. This study mainly evaluated the effects of SS on ruminal fermentation, microflora and urinary excretion of purine derivatives (PD) in dairy bulls. Eight ruminally cannulated dairy bulls were used in a replicated 4 × 4 Latin square design.

Application of data mining methods to improve screening for the risk of early gastric cancer.

Background: Although gastric cancer is a malignancy with high morbidity and mortality in China, the survival rate of patients with early gastric cancer (EGC) is high after surgical resection. To strengthen diagnosing and screening is the key to improve the survival and life quality of patients with EGC. This study applied data mining methods to improve screening for the risk of EGC on the basis of noninvasive factors, and displayed important influence factors for the risk of EGC.
