Visualization of the ribosomal DNA (45S rDNA) of Indica rice with FISH on some phases of cell cycle and extended DNA fibers

The ribosomal DNA (45S rDNA) behaviors during the cell cycle were analyzed on interphase nuclei, prophases, metaphases, pachytene chromosomes and extended DNA fibers in rice (Oryza,sativa ssp.indica cv.Guangluai No.4) by using high-resolution fluorescent in situ hybridization (FISH). The results show that 45S rDNA is located at the ends of short arms of chromosomes 9 and 10. But the signals are much more intense on chromosome 9 than on chromosome 10 in metaphase. Pachytene chromosome has rDNA signal arrays on chromosome 9. Different phases are described and discussed. These results indicate that the activity of rDNA at individual loci may also vary through the cell cycle in rice. on extended DNA fibers, 45S rDNA signals appear as strings of numerous red spots, but some signals are missed in some regions, probably result from weak signals or intergenic spacers

Clinical Analysis of 1308 Patients Received Hysterectomy / 中国康复理论与实践

@#ObjectiveTo compare the surgical outcomes of total abdominal hysterectomy (TAH) and total vaginal hysterectomy (TVH).MethodsThe clinical data of 509 TAH cases and 799 TVH cases including operating time, bleeding volume, days being in hospital and outcome of 3 months following-up were analyzed retrospectively.ResultsThe average operating time and bleeding volume of TVH were 47.6 minutes and 199 ml respectively, less than that of TAH (128 minutes and 241 ml). The days being in hospital of TVH were also less that of TAH, and 12-Short Form Health Survey (SF-12) scores of TVH were higher than that of TAH.ConclusionTVH has minor lesion and is helpful for improving the quality of patients' life.
