Cereal opaque-kernel mutants are ideal geneticmaterials for studying the mechanism of starch biosynthesisand amyloplast development. Here we isolated and identifiedtwo allelic floury endosperm 8 (flo8) mutants of rice, namedflo8-1 and flo8-2. In the flo8 mutant, the starch content wasdecreased and the normal physicochemical features ofstarch were altered. Map-based cloning and subsequentDNA sequencing analysis revealed a single nucleotidesubstitution and an 8-bp insertion occurred in UDP-glucosepyrophosphorylase 1 (Ugp1) gene in flo8-1 and flo8-2,respectively. Complementation of the flo8-1 mutant restorednormal seed appearance by expressing full length codingsequence of Ugp1. RT-qPCR analysis revealed that Ugp1was ubiquitously expressed. Mutation caused the decreasedUGPase activity and affected the expression of most of genesassociated with starch biosynthesis. Meanwhile, western blotand enzyme activity analyses showed the comparability ofprotein levels and enzyme activity of most tested starchbiosynthesis related genes. Our results demonstrate thatUgp1 plays an important role for starch biosynthesis in riceendosperm.

Objective: To determine the effect of body mass index on postoperative complications and the performance of lymph node dissection in women undergoing laparoscopy or laparotomy for endometrial cancer. Methods: Retrospective chart review of all patients undergoing surgery for endometrial cancer between 8/2004 and 12/2008. Complications graded and analyzed using Common Toxicity Criteria for Adverse Events ver. 4.03 classification. Results: 168 women underwent surgery: laparoscopy n=65, laparotomy n=103. Overall median body mass index 36.2 (range, 18.1 to 72.7) with similar distributions for age, body mass index and performance of lymph node dissection between groups. Following laparoscopy vs. laparotomy the percent rate of overall complications 53.8:73.8 (p=0.01), grade ≥3 complications 9.2:34.0 (p<0.01), ≥3 wound complications 3.1:22.3 (p<0.01) and ≥3 wound infection 3.1:20.4 (p=0.01) were significantly lower after laparoscopy. In a logistic model there was no effect of body mass index (≥36 and<36) on complications after laparoscopy in contrast to laparotomy. Para-aortic lymph node dissection was performed by laparoscopy 19/65 (29%): by laparotomy 34/103 (33%) p=0.61 and pelvic lymph node dissection by laparoscopy 21/65 (32.3%): by laparotomy 46/103 (44.7%) p=0.11. Logistic regression analysis revealed that for patients undergoing laparoscopy for stage I disease there was an inverse relationship between the performance of both para-aortic lymph node dissection and pelvic lymph node dissection and increasing body mass index (p=0.03 and p<0.01 respectively) in contrast to the laparotomy group where there was a trend only (p=0.09 and 0.05). Conclusion: For patients undergoing laparoscopy, increasing body mass index did not impact postoperative complications but did influence the decision to perform lymph node dissection.
