Microcalorimetric Studies on Gene Promoter Function of Cloned DNA Fragements from Halobacterium halobium J7 Plasmid pHH205 in Escherichia coli TG1
Authors: Lei Ke‐Lin , Hou Han‐Na , Liu Yi , Ye Xue‐Cheng , Shen Ping 
Published: August 2007

AbstractHalobacterium halobium is a typical kind of extremely halophilic bacterium. Combined with the antibiotic resistance assay, the microcalorimetric method was used to study the promoter function of the cloned DNA fragments from Halobacterium halobium J7 plasmid pHH205 in Escherichia coli TG1. The promoter probe vector, plasmid pKK232‐8, was used to form the recombinants. The DNA fragment, which is the promoter for the chloramphenicol acetyl transferase (CAT) gene in plasmid pKK232‐8, is about 800 bp, and the chloramphenicol resistance level presented by IC50 is about 200 µg·mL−1, which suggests a high promoter activity. The conclusions show that there probably exist double‐function or trinary‐function gene promoters in Halobacterium halobium, and Archaea may contain rich genetic resources.
Detection of Radical Adducts with Small Molecular Weights by Matrix‐Assisted Laser Desorption/Ionization with Fourier Transform Mass Spectrometry
Authors: Tian Yao‐Wei , Sun Shi‐Hao , Xie Jian‐Ping , Zong Yong‐Li , Nie Cong , Guo Yin‐Long 
Published: August 2007

AbstractAs an alternative method, matrix‐assisted laser desorption/ionization with Fourier transform mass spectrometry (MALDI‐FTMS) has been successfully used to detect and identify free radical adducts with small molecular weights of hydroxyl and 2‐cyano‐2‐propyl radicals trapped with 5,5‐dimethylpyrroline N‐oxide (DMPO). The detection and identification by MS/MS experiments using sustained offresonance irradiation collision‐induced dissociation (SORI‐CID) of [(DMPO+·OH–·H)+H+] (m/z 130.0868) and [DMPO+2 ·CH(CH3)2CN+H+] (m/z 250.1917) have demonstrated that MALDI‐FTMS could be an effective method for detection and identification of free radical adducts. Other radical adducts have been also detected and identified. The approach of MALDI‐FTMS is simple, fast, and sensitive which has potential for high‐throughput analysis.
Investigation of the Interaction between Isoflavonoids and Bovine Serum Albumin by Fluorescence Spectroscopy
Authors: Qu Ling‐Bo , Chen Xiao‐Lan , Yang Ran , Wang Ling , Zeng Hua‐Jin 
Published: August 2007

AbstractThe interactions of bovine serum albumin (BSA) with three structurally related isoflavonoids, genistein, puerarin and daidzein, were studied under physiological conditions by fluorescence spectroscopic technique. The quenching mechanism of these compounds with BSA was suggested as static quenching and the binding constants were determined at different temperatures based on the fluorescence quenching results. The transfer efficiency of energy and distance between the acceptor and BSA were investigated on the basis of the mechanism of the Förster energy transference. According to the thermodynamic parameters it has been suggested that the acting force be mainly hydrophobic force. The comparison of binding potency of the three isoflavonoids to BSA showed that the substitution by 5‐OH and 8‐Glc could enhance the binding affinity. All these obtained in the work can make us better understand the mode of the action and pharmacological activities of the isoflavonoids.
Experimental multi‐level seismic performance assessment of 3D RC frame designed for damage avoidance
Authors: Bradley Brendon A. , Dhakal Rajesh P. , Mander John B. , Li Louman 
Published: August 2007

AbstractThis paper experimentally investigates the application of damage avoidance design (DAD) philosophy to moment‐resisting frames with particular emphasis on detailing of rocking interfaces. An 80% scale three‐dimensional rocking beam–column joint sub‐assembly designed and detailed based on damage avoidance principles is constructed and tested. Incremental dynamic analysis is used for selecting ground motion records to be applied to the sub‐assembly for conducting a multi‐level seismic performance assessment (MSPA). Analyses are conducted to obtain displacement demands due to the selected near‐ and medium‐field ground motions that represent different levels of seismic hazard. Thus, predicted displacement time histories are applied to the sub‐assembly for conducting quasi‐earthquake displacement tests. The sub‐assembly performed well reaching drifts up to 4.7% with only minor spalling occurring at rocking beam interfaces and minor flexural cracks in beams. Yielding of post‐tensioning threaded bars occurred, but the sub‐assembly did not collapse. The externally attached energy dissipators provided large hysteretic dissipation during large drift cycles. The sub‐assembly satisfied all three seismic performance requirements, thereby verifying the superior performance of the DAD philosophy. Copyright © 2007 John Wiley & Sons, Ltd.
PVRL2 is translocated to the TRA@ locus in t(14;19)(q11;q13)‐positive peripheral T‐cell lymphomas

Published: August 2007

AbstractVery few recurrent chromosomal abnormalities have been identified in T‐cell non‐Hodgkin lymphomas. These involve the TRA@/TRD@ gene at chromosome band 14q11 in up to 15% of cases. We recently reported a novel and recurrent translocation, t(14;19)(q11;q13), in peripheral T‐cell lymphoma (PTCL). Fluorescence in situ hybridization analysis performed in three cases suggested an involvement of the TRA@/TRD@ locus at 14q11 and of a region telomeric to BCL3 on 19q13. We now report the molecular cloning of these translocations. Sequence analysis confirmed the involvement of the TRA@/TRD@ and indicated that the breakpoints were located mainly in the TRAJ region. On chromosome 19, our results revealed a new clustering of breakpoints outside the region involved in t(14;19)(q32;q13)‐positive B‐cell malignancies. Remarkably, all three breaks were located downstream or within the PVRL2 gene, in a small 10.3 kb interval, suggesting a nonrandom location of the breakpoints. For two patients, a high mRNA expression of both PVRL2 and BCL3 was found. In conclusion, we identified PVRL2 as a new recurrent partner gene of the TRA@ locus in PTCL. These results suggest that both BCL3 and PVRL2 may participate in the pathogenesis of these PTCLs, but further studies should be undertaken to investigate the precise role of these genes. © 2007 Wiley‐Liss, Inc.
A numerical study of moisture build‐up and rainfall over West Africa
Authors: Omotosho J. 'Bayo , Abiodun Babatunde J. 
Published: August 2007

AbstractEmpirical studies have shown that a necessary condition for abundant rainfall in any year at Kano in Nigeria is a pre‐rainy season moisture build‐up for 6–8 weeks at the surface or below 800 hPa. The International Centre for Theoretical Physics (ICTP) regional climate model (RegCM3) is used to study the mechanism and variability of the inflow of this moisture over West Africa over a 21‐year period (1980–2000). The study focused on three dry (1983, 1989 and 1990) and three wet years (1980, 1988 and 1996) and uses rainfall and other surface data such as specific humidity, over Nigeria for the same years for model validation. Comparison of RegCM3 simulation of rainfall and moisture patterns over West Africa with both CRU and Nigerian stations observations shows that the model performed very well with respect to the observations over the region, particularly over the Sahel and Savana zones.The composites of moisture inflow and wind anomalies for the wet years are found to be associated with areas of boundary layer moisture build‐up, overlain by relatively drier (but still moist) air driven by strong west to southwest wind vector anomalies at 700 hPa (African Easterly Jet, AEJ, level). These strong wind anomalies, which occur south of the AEJ between May and September and transport moisture towards it, seem unconnected with the boundary layer winds and are not found in the dry composites. In sharp contrast, the dry composites are characterized by negative moisture anomalies in the boundary layer overlain by drier than normal air associated with northerly to easterly wind anomalies at the AEJ level. Secondly, while the ITD reached the same northernmost limit of about 20°N in August during both dry and wet periods, the AEJ advanced faster across West Africa, reaching a mean position of 16.5°N in August during wet years but 15°N in dry years. Also, on a monthly and inter‐annual basis, moisture adequacy and variability analysis show that, for dry years, moisture build‐up is delayed but starts early and strongly during wet years. Furthermore, rainfall does not begin properly until about 2.5 months after the start of the moisture build‐up. Finally, RegCM3 predicted rainfall correlates very well (r ≥ 0.6) with observed rainfall for stations within Nigeria. Copyright © 2007 Royal Meteorological Society
