In searching.of differentially expressed g.nes in human uterine leiomyomas, differential display was used with twelve pairs of primers to compare human uterine leiomyomas with matched myometrium. False positives were e{2.minated by reverse Northern analysis. Positives were confirmed by Northern blot analysis. RESULTS: [1] Four of 69 cDNA frag.ents (3 up-reg.lated named L1, L2.and L3 and 1 down-reg.lated named Mi in leiomyoma) were confirmed by Northern analysis. [2. Sequence comparison and Northern analysis proved that {2. is exactly the human ribosomal protein Si9. [3] It was present ubiquitously in i3 tissues tested but in various levels and even in different size. [4] {2. was hig.ly expressed in parotidean cystadenocarcinoma, pancreatic cancer and breast cancer examined. [5] No mutations have been found in human uterine leiomyomas (n=6). CONCLUSIONS: hRPSi9 overexpression mig.t be a universal sig.al in rapid cell g.owth tissues.

This paper proposes a novel hash alg.rithm whose security is based on the multivariate nonlinear polynomial equations of NP-hard problem over a finite field and combines with HAIFA iterative framework. Over the current widely used hash alg.rithms, the new alg.rithm has the following.advantag.s: its security is based on a recog.ized difficult mathematical problem; the hash leng.h can be chang.d freely; its desig. can be automated such that users may construct specific hash function meeting.the actual needs. Furthermore, we discuss the security, efficiency and performance of the new alg.rithm. Under some related difficult mathematical assumptions and theoretical analysis, the new alg.rithm is proven practical by the experiment results, and capable of achieving.security of an ideal hash function by choosing.suitable parameters. In addition, it can also be used as a pseudo-random number g.nerator for the g.od randomness of its output.

A bioflocculant-producing.mutator strain, NIM-192. was screened out throug. nitrog.n ion implanting.into F j.7 strain. The results showed that NIM-192.had g.od g.netic stability and hig. flocculating.activity, and the flocculating.rate increased by 34.2.% than that of the orig.nal. Sucrose, complex nitrog.n source contained yeast extract, urea and pH 7.0～ 9.0 were chosen as the best carbon source, nitrog.n source and initial solution pH for bioflocculant production, respectively. The bioflocculant kept hig. and stable flocculating.activity at alkalinous reaction mixture with a pH beyond 7.0, while the flocculating.activity was remarkably reduced when the reaction pH was lower than 7.0. Addition of many cations could obviously increase the flocculating.rate, among.which Ca^2. demonstrated the best effect. The bioflocculant had very strong.acid-base stability and *** flocculating.rate kept over 86% when pH of the bioflocculant was in a rang. of 3.0 ～ 12.0, and the chang. of flocculating.activity was not g.eat when heated at 100℃ for 60 rain.

Meanwhile, several optimization strateg.es for parallel computing.of Og.M (POg.M) on Scalable Shared Memory Multiprocessor (S2.P) are presented. Using.Messag. Passing.Interface (MPI), we obtain super linear speedup on Sg. Orig.n 2.00 for parallel Og.M(POg.M) after optimization.

An unusual zircon SHRIMP dating.result of a g.anitic g.eiss from the Qing.ong.han eclog.te-g.eiss roadcut section is presented in this paper. The very peculiar and complicated internal structures, as well as the very low Th/U ratios (0.01-0.08) of the zircons indicate that they were formed by metamorphic recrystallization. Strong.y in contrast with previously published zircon U-Pb ag.s of the Dabie-Sulu UHP metamorphic rocks where protolith ag.s of 600-800 Ma are commonly recorded, only metamorphic ag. of 2.8±5 Ma, defined by 18 analytical spots either in rim or in core of zircons, are recorded in this g.anitic g.eiss. This ag. represents the time of the complete metamorphic recrystallization overprint on primary mag.atic zircons. The recrystallization was derived by the UHP metamorphism, and was streng.hened by the early stag. of retrog.ade metamorphic fluid activity.
