Abstract
We report the first three-particle coincidence measurement in pseudorapidity (Δη) between a high transverse momentum (p⊥) trigger particle and two lower p⊥ associated particles within azimuth |Δϕ|<0.7 in square root of s(NN)=200 GeV d+Au and Au+Au collisions. Charge ordering properties are exploited to separate the jetlike component and the ridge (long range Δη correlation). The results indicate that the correlation of ridge particles are uniform not only with respect to the trigger particle but also between themselves event by event in our measured Δη. In addition, the production of the ridge appears to be uncorrelated to the presence of the narrow jetlike component.

Abstract
BACKGROUND Sertoli cells (SCs) have been described as the 'nurse cells' of the testis whose primary function is to provide essential growth factors and create an appropriate environment for development of other cells [for example, germinal and nerve stem cells (NSCs), used here]. However, the greatest challenge at present is that it is difficult to obtain sufficient SCs of normal physiological function for cell transplantation and biological medicine, largely due to traditional static culture parameter difficult to be monitored and scaled up. OBJECTIVE Operational stirred culture conditions for in vitro expansion and differentiation of SCs need to be optimized for large-scale culture. MATERIALS AND METHODS In this study, the culturing process for primary SC expansion and maintaining lack of differentiation was optimized for the first time, by using microcarrier bead technology in spinner flask culture. Effects of various feeding/refreshing regimes, stirring speeds, seed inoculum levels of SCs, and concentrations of microcarrier used for expansion of mouse SCs were also explored. In addition, pH, osmotic pressure and metabolic variables including consumption rates of glucose, glutamine, amino acids, and formation rates of lactic acid and ammonia, were investigated in culture. RESULTS After 6 days, maximal cell densities achieved were 4.6 x 10(6) cells/ml for Cytodex-1 in DMEM/FBS compared to 4.8 x 10(5) cells/ml in static culture. Improved expansion was achieved using an inoculum of 1 x 10(5) cells/ml and microcarrier concentration of 3 mg/ml at stirring speed of 30 rpm. RESULTS indicated that medium replacement (50% changed everyday) resulted in supply of nutrients and removal of waste products inhibiting cell growth, that lead to maintenance of cultures in steady state for several days. These conditions favoured preservation of SCs in the undifferentiated state and significantly increased their physiological activity and trophic function, which were assessed by co-culturing with NSCs and immunostaining. CONCLUSION Data obtained in this study demonstrate the vast potential of this stirred culture system for efficient, reproducible and cost-effective expansion of SCs in vitro. The system has advantages over static culture, which has major obstacles such as lower cell density, is time-consuming and susceptible to contamination.

Abstract
A perfusion culture system was developed to investigate the oxygenation of high-density hybridoma cell cultures. The culture system was composed of a stirred-tank bioreactor and an external microfiltration hollow fiber cartridge for medium perfusion. Cell growth and antibody production were examined with large bubble ( approximately 5 mm in diameter), micron-sized bubble ( approximately 80 mum in diameter), and silicone tubing oxygenation techniques. Comparable cell growth and monoclonal antibody (MAb) production were found for both the micron-sized and large oxygenation methods, provided that large bubbles were enriched with pure oxygen. Relatively low cell growth and MAb production were attained with the bubble-free silicone tubing oxygenation. It is concluded that direct bubble oxygenation can be applied successfully in high-density animal cell cultures, provided that the culture medium is supplemented with Pluronic F-68. The accumulation of ammonia in the culture medium rather than oxygen limitation was found to be one of the possible problems that eventually inhibited cell growth. This and the fouling of the filtration cartridge during long-term cultivation were found to be more problematic than simple bubble oxygenation of high-density cell culture. The micron-sized bubble oxygenation method is highly recommended for high-density animal cell cultures, provided that Pluronic F-68 is supplemented into the culture medium.

Abstract
An oncogenic form of RHAMM (receptor for hyaluronan-mediated motility, mouse, amino acids 163-794 termed RHAMM(Delta163)) is a cell surface hyaluronan receptor and mitotic spindle protein that is highly expressed in aggressive human cancers. Its regulation of mitotic spindle integrity is thought to contribute to tumor progression, but the molecular mechanisms underlying this function have not previously been defined. Here, we report that intracellular RHAMM(Delta163) modifies the stability of interphase and mitotic spindle microtubules through ERK1/2 activity. RHAMM(-/-) mouse embryonic fibroblasts exhibit strongly acetylated interphase microtubules, multi-pole mitotic spindles, aberrant chromosome segregation, and inappropriate cytokinesis during mitosis. These defects are rescued by either expression of RHAMM or mutant active MEK1. Mutational analyses show that RHAMM(Delta163) binds to alpha- and beta-tubulin protein via a carboxyl-terminal leucine zipper, but in vitro analyses indicate this interaction does not directly contribute to tubulin polymerization/stability. Co-immunoprecipitation and pulldown assays reveal complexes of RHAMM(Delta163), ERK1/2-MEK1, and alpha- and beta-tubulin and demonstrate direct binding of RHAMM(Delta163) to ERK1 via a D-site motif. In vitro kinase analyses, expression of mutant RHAMM(Delta163) defective in ERK1 binding in mouse embryonic fibroblasts, and blocking MEK1 activity collectively confirm that the effect of RHAMM(Delta163) on interphase and mitotic spindle microtubules is mediated by ERK1/2 activity. Our results suggest a model wherein intracellular RHAMM(Delta163) functions as an adaptor protein to control microtubule polymerization during interphase and mitosis as a result of localizing ERK1/2-MEK1 complexes to their tubulin-associated substrates.

Abstract
Staphylococcal enterotoxin C2 (SEC2) is one of the most potent known activators of human T lymphocytes, and recombinant SEC2 shows promising clinical values, but SEC2 can cause food poisoning and toxic shock syndrome in vivo. In this study, site-directed mutagenesis has been used to introduce alanine substitutions at Phe144 and Leu45 in the molecule. The mutant genes were cloned and expressed, and the corresponding proteins were purified by nickel agarose affinity chromatography. We found that the SEC2 mutant proteins could stimulate the proliferation of human peripheral blood lymphocytes and inhibit the growth of tumour cells as native SEC2. Furthermore, flow cytometry assay showed that mSEC2(F44A, L45A) drastically reduced the ability of the toxin to bind to MHC class II. Physiological parameters revealed that mSEC2(F44A, L45A) reduced significantly rat temperature compared with native SEC2 in vivo. Our results clearly suggest that this genetically modified SEC2 protein is less toxic and justifies its further development as a new, safer antitumour superantigen to prevent SEC2 intoxication.

Abstract
AIMS/HYPOTHESIS Treatment with the Cu(II)-selective chelator triethylenetetramine (TETA) improves cardiovascular disease in human patients, and cardiac and vascular/renal disease in rats used as a model of diabetes. Here we tested two hypotheses: first, that TETA elicits greater improvement in organ function than less Cu-selective transition-metal-targeted treatments; second, that the therapeutic actions of TETA are consistent with mediation through suppression of oxidative stress. METHODS Rats were made diabetic with streptozotocin (55 mg/kg, i. v.) and treated from 8 weeks after disease induction for the following 8 weeks with effective dosages of oral TETA, or one of three less Cu-selective transition-metal-targeted treatments: D-penicillamine, deferiprone or Zn acetate. Treatment effects were measured in ex vivo cardiac and aortic tissues, plasma and urine. RESULTS Diabetes damaged both cardiac and renal/vascular function by impairing the ability of cardiac output to respond physiologically to rising afterload, and by significantly elevating the urinary albumin/creatinine ratio. Diabetes also lowered total antioxidant potential and heparan sulphate levels in cardiac and arterial tissues, and serum ferroxidase activity, whereas it elevated urinary heparan sulphate excretion. TETA treatment rectified or partially rectified all these defects, whereas the other three experimental treatments were ineffectual. By contrast, none of the four drug treatments lowered diabetes-mediated elevations of plasma glucose or lipid concentrations. CONCLUSIONS/INTERPRETATION TETA may limit the cardiac and renal/vascular damage inflicted by diabetes through its actions to reinforce antioxidant defence mechanisms, probably acting through selective chelation of 'loosely-bound'/chelatable Cu(II). It may also improve heparan sulphate homeostasis and bolster antioxidant defence by increasing vascular extracellular superoxide dismutase activity. Urinary albumin/creatinine ratio might prove useful for monitoring TETA treatment.

Abstract
This was a two-phase, large sample-group study assessing the effectiveness of combined transvaginal sonography (TVS) and endometrial cytology in endometrial cancer screening. In phase one, 3308 women without known cancer were enrolled and TVS was performed on those with symptoms or endometrial cancer risk factors. Endometrial cytology was carried out on post-menopausal women with endometrial thickness ≥ 5 mm and on pre-menopausal women with endometrial thickness ≥ 10 mm. Dilation and curettage (D & C) was performed if cytological findings were inconclusive, or indicated cancer or pre-cancer. The mass screening safety interval is at least 2 years and phase two was carried out 2 years after phase one, using the same procedures, on the 3305 women who were originally found to be cancer free. Combined TVS and endometrial cytology resulted in 100% sensitivity and 99.0% specificity, reducing unnecessary D & C by 91.7% and screening costs by 20.1%. Combined TVS examination and endometrial cytology decreased potentially harmful examinations, patient suffering and medical costs, and is worth considering for broad implementation.

Abstract
AIMS Escherichia coli has emerged as a viable heterologous host for the production of complex, polyketide natural compounds. In this study, polyketide biosynthesis was compared between different E. coli strains for the purpose of better understanding and improving heterologous production. METHODS AND RESULTS Both B and K-12 E. coli strains were genetically modified to support heterologous polyketide biosynthesis [specifically, 6-deoxyerythronolide B (6dEB)]. Polyketide production was analysed using a helper plasmid designed to overcome rare codon usage within E. coli. Each strain was analysed for recombinant protein production, precursor consumption, by-product production, and 6dEB biosynthesis. Of the strains tested for biosynthesis, 6dEB production was greatest for E. coli B strains. When comparing biosynthetic improvements as a function of mRNA stability vs codon bias, increased 6dEB titres were observed when additional rare codon tRNA molecules were provided. CONCLUSIONS Escherichia coli B strains and the use of tRNA supplementation led to improved 6dEB polyketide titres. SIGNIFICANCE AND IMPACT OF THE STUDY Given the medicinal potential and growing field of polyketide heterologous biosynthesis, the current study provides insight into host-specific genetic backgrounds and gene expression parameters aiding polyketide production through E. coli.

Abstract
OBJECTIVE Recent data suggest that soluble CD40L (sCD40L) plays an important role in murine sepsis. The aim of the present study was to determine plasma levels of CD40L in critically ill patients with systemic inflammatory response syndrome (SIRS) and shock, with and without sepsis. DESIGN A prospective observational one-centre cohort study in a mixed-bed ICU of an university hospital. Fifty-three consecutive patients fulfilling the criteria for SIRS with shock as well as seven age-matched controls were included. ELISA was used to determine sCD40L in the plasma. RESULTS The level of sCD40L in plasma from healthy controls was 0.18 ± 0.03 ng/ml. It was found that sCD40L levels were significantly higher in patients with non-septic shock (0.72 ± 0.18 ng/ml) and septic shock (0.50 ± 0.1 ng/ml). However, the levels of sCD40L were not different between these two groups of patients, or in those with low and high APACHE scores. CONCLUSION Our data show that sCD40L is increased in patients with shock from septic and non-septic etiologies. However, further studies are needed to delineate the functional significance of sCD40L in the clinical outcome in shock patients.

Abstract
AIMS A simple and rapid method (designated thermolysis) for extracting genomic DNA from bulk fungal strains was described. METHODS AND RESULTS In the thermolysis method, a few mycelia or yeast cells were first rinsed with pure water to remove potential PCR inhibitors and then incubated in a lysis buffer at 85 degrees C to break down cell walls and membranes. This method was used to extract genomic DNA from large numbers of fungal strains (more than 92 species, 35 genera of three phyla) isolated from different sections of natural Ophiocordyceps sinensis specimens. Regions of interest from high as well as single-copy number genes were successfully amplified from the extracted DNA samples. The DNA samples obtained by this method can be stored at -20 degrees C for over 1 year. CONCLUSIONS The method was effective, easy and fast and allowed batch DNA extraction from multiple fungal isolates. SIGNIFICANCE AND IMPACT OF STUDY Use of the thermolysis method will allow researchers to obtain DNA from fungi quickly for use in molecular assays. This method requires only minute quantities of starting material and is suitable for diverse fungal species.

Abstract
A novel 407 bp nucleotide sequence NTPp13 was isolated from tobacco (Nicotiana tabacum L.) by PCR, its structure and function were characterized. The NTPp13 sequence was highly homologous with the pollen-specific expression promoter Zm13 from maize (Zea mays L.) and contained some key motifs which controlled pollen-specific expression. The NTPp13 was fused to the beta-glucuronidase (GUS) reporter gene and transferred into tobacco. Analysis of the transgenic plants revealed that this putative promoter fragment was sufficient to direct GUS expression specifically in the anther, exactly in the pollen and pollen tube, and that GUS activity reached the maximum at the stage of pollen grain began to separate. Further study showed that the expression of NTPp13 sequence at pollen was stable at the range of temperature measured. These data suggested that the NTPp13 sequence was likely the essential element of promoter region of an unknown pollen-specific gene from tobacco.
