Abstract
The excitement of nano-test-tube chemistry in a single-walled carbon nanotube is exemplified in our study on electron doping in carbon nanotubes. Electron doping through the 1D van Hove singularity of single-walled carbon nanotubes is realized via a chemical reaction of an encapsulated organocerium compound, CeCp3. The decomposition of CeCp3 inside the carbon nanotubes increases the doping level and greatly enhances the density of conduction electrons. The transition of the cerium encapsulating semiconducting tubes to metallic results in enhanced screening of the photoexcited core hole potential. This fact illustrates the importance of many body effects in understanding core-level excitation process in carbon nanotubes.

Abstract
We present measurements of the linear polarization amplitudes and the strong relative phases that describe the flavor-untagged decays Bd0-->J/psiK*0 and Bs0-->J/psiphi in the transversity basis. We also measure the mean lifetime taus of the Bs0 mass eigenstates and the lifetime ratio taus/taud. The analyses are based on approximately 2.8 fb(-1) of data recorded with the D0 detector. From our measurements of the angular parameters we conclude that there is no evidence for a deviation from flavor SU(3) symmetry for these decays and that the factorization assumption is not valid for the Bd0-->J/psiK*0 decay.

Abstract
A genetic evaluation system was developed for 5 fertility traits of dairy cattle: interval from first to successful insemination and nonreturn rate to 56 d of heifers, and interval from calving to first insemination, nonreturn rate to 56 d, and interval first to successful insemination of cows. Using the 2 interval traits of cows as components, breeding values for days open were derived. A multiple-trait animal model was applied to evaluate these fertility traits. Fertility traits of later lactations of cows were treated as repeated measurements. Genetic parameters were estimated by REML. Mixed model equations of the genetic evaluation model were solved with preconditioned conjugate gradients or the Gauss-Seidel algorithm and iteration on data techniques. Reliabilities of estimated breeding values were approximated with a multi-trait effective daughter contribution method. Daughter yield deviations and associated effective daughter contributions were calculated with a multiple trait approach. The genetic evaluation software was applied to the insemination data of dairy cattle breeds in Germany, Austria, and Luxembourg, and it was validated with various statistical methods. Genetic trends were validated. Small heritability estimates were obtained for all the fertility traits, ranging from 1% for nonreturn rate of heifers to 4% for interval calving to first insemination. Genetic and environmental correlations were low to moderate among the traits. Notably, unfavorable genetic trends were obtained in all the fertility traits. Moderate to high correlations were found between daughter yield-deviations and estimated breeding values (EBV) for Holstein bulls. Because of much lower heritabilities of the fertility traits, the correlations of daughter yield deviations with EBV were significantly lower than those from production traits and lower than the correlations from type traits and longevity. Fertility EBV were correlated unfavorably with EBV of milk production traits but favorably with udder health and longevity. Integrating fertility traits into a total merit selection index can halt or reverse the decline of fertility and improve the longevity of dairy cattle.

Abstract
BACKGROUND Osteopontin (OPN) is a multifunctional 34-kDa extracellular matrix protein that can influence the inflammatory process. However, the presence of OPN in human sinonasal mucosa and its roles in the inflammatory process of chronic rhinosinusitis (CRS) are not clear. This study investigated the expression of OPN in human sinonasal mucosa, its cytokine-driven expression regulation, and its effect on cytokine production in sinonasal mucosa. METHODS Surgical samples were investigated by means of quantitative reverse transcriptase polymerase chain reaction for evaluation of OPN messenger RNA (mRNA) expression, and the presence and location of OPN protein expression were analyzed using immunohistochemistry. Furthermore, nasal explant culture was used to investigate the mutual regulatory interactions between interferon (IFN)-gamma, interleukin (IL)-4, IL-5, IL-13, IL-1beta, and tumor necrosis factor (TNF)-alpha and OPN in sinonasal mucosa. RESULTS Osteopontin expression was significantly upregulated in CRS tissues compared with control tissues. There was a further significant increase of OPN expression in patients with nasal polyps (NPs) and asthma. Immunohistochemistry revealed positive staining of OPN in epithelial cells, submucosal glands, infiltrating cells, and extracellular matrix. Osteopontin mRNA was induced by IFN-gamma, IL-1beta, and TNF-alpha, but inhibited by IL-4 and IL-13. On the contrary, OPN induced IFN-gamma, IL-4, IL-5, IL-13, IL-1beta, and TNF-alpha production in sinonasal mucosa. CONCLUSIONS The expression of OPN is upregulated in CRS. The mutual regulatory interactions between OPN and inflammatory cytokines suggest that OPN may play an important role in the pathogenesis of CRS.

Abstract
BACKGROUND Clara cell 10-kDa protein (CC10) is a multifunction protein with anti-inflammatory and immunomodulatory effects; hence we compared the CC10 expression between chronic rhinosinusitis (CRS) patients with and without nasal polyps (NPs), analyzed its association with disease severity and response to surgery, and explored its regulation via cytokines. METHODS The plasma and tissue CC10 levels were compared between controls and CRS patients with and without NPs by means of quantitative RT-PCR, ELISA, and immunohistochemistry. Computed tomography (CT) scan and endoscopy findings and symptoms were scored. Nasal explant culture was used to explore the effect of TNF-alpha, IL-1beta, IL-4, INF-gamma, and IL-10 on CC10 gene regulation. RESULTS Compared with controls, the CC10 expression in sinonasal mucosa was significantly inhibited in both CRS patients with and without NPs. There was a significant further decrease of CC10 expression in patients with NPs and asthma. No difference in CC10 plasma levels was found between controls and patients. CC10 levels inversely correlated with preoperative CT scores, and postoperative endoscopy and symptom scores. TNF-alpha, IL-1beta and IL-4 inhibited, whereas INF-gamma and IL-10 promoted CC10 production in nasal mucosa. A significantly faster decay of CC10 transcripts was seen after IL-1beta treatment. IL-1beta and IL-10 induced thyroid transcription factor-1 expression. INF-gamma increased, whereas IL-4 inhibited hepatocyte nuclear factor-3alpha expression. CONCLUSION CC10 may take part in the pathogenesis of CRS and correlates with disease severity and response to surgery. Different cytokines can regulate CC10 expression in nasal mucosa differentially through modulating mRNA stability and certain transcriptional factors expression.

Abstract
OBJECTIVE To observe the influence of the Tripterygium wilfordii Hook F (T II) on the blood concentration of tacrolimus and analyze the impact of this effect. METHOD Twenty-two renal transplant receipts taking tacrolimus combined with the T II were selected for this study. We analyzed the blood concentrations and the rate of concentration compared with dosage (C/D rate) pre- and postcombination over 6 months. All cases underwent the CYP3A5 genotype test. RESULT The concentrations of tacrolimus were raised to a certain degree after the combination in all the cases. The first-time elevation differed from 1 week to 4 months. The C/D rate increased by 1.7 to 7.2 times with most evaluated C/D rates ranging from 1.8 to 3.8. The elevated C/D rate of the subgroup of CYP3A5 1/1 and 1/3 (n = 10) contrasted with the 3/3 genotype subgroup (n = 12: 2.99 +/- 1.71 vs 2.55 +/- 1.07; P = .472). The mycophenolate mofetil subgroup (n = 17) was not contrasted to the mizoribine subgroup (n = 5: 2.85 +/- 1.51 vs 2.31 +/- 0.26; P = .498). CONCLUSION T II considerably increased the blood concentration and the C/D rate of tacrolimus. The degree of increase was probably not related to the CYP3A5 genotype and the combination of immunosuppressive agents.

Abstract
We report a search for the standard model Higgs boson in the missing energy and acoplanar b-jet topology, using an integrated luminosity of 0.93 fb;{-1} recorded by the D0 detector at the Fermilab Tevatron pp[over ] Collider. The analysis includes signal contributions from pp[over ]-->ZH-->nunu[over ]bb[over ], as well as from WH production in which the charged lepton from the W boson decay is undetected. Neural networks are used to separate signal from background. In the absence of a signal, we set limits on sigma(pp[over ]-->VH)xB(H-->bb[over ]) at the 95% C.L. of 2.6-2.3 pb, for Higgs boson masses in the range 105-135 GeV, where V=W, Z. The corresponding expected limits range from 2.8 to 2.0 pb.

Abstract
We have searched for third generation leptoquarks (LQ3) using 1.05 fb(-1) of data collected with the D0 detector at the Fermilab Tevatron Collider operating at sqrt[s]=1.96 TeV. We set a 95% C.L. lower limit of 210 GeV on the mass of a scalar LQ3 state decaying solely to a b quark and a tau lepton.

Abstract
From an analysis of the flavor-tagged decay Bs0-->J/psiphi we obtain the width difference between the Bs0 light and heavy mass eigenstates, DeltaGammas = 0.19+/-0.07(stat)(-0.01)+0.02(syst) ps(-1), and the CP-violating phase, phi s= -0.57(-0.30)+0.24(stat)(-0.02)+0.08(syst). The allowed 90% CL intervals of DeltaGammas and phi s are 0.06 < DeltaGammas < 0.30 ps(-1) and -1.20 < phi s < 0.06, respectively. The data sample corresponds to an integrated luminosity of 2.8 fb(-1) accumulated with the D0 detector at the Fermilab Tevatron collider.

Abstract
We report the observation of the doubly strange b baryon Omegab- in the decay channel Omegab(-)-->J/psiOmega-, with J/psi-->mu+mu(-) and Omega(-)-->LambdaK(-)-->(ppi-)K-, in pp collisions at sqrt[s]=1.96 TeV. Using approximately 1.3 fb(-1) of data collected with the D0 detector at the Fermilab Tevatron Collider, we observe 17.8+/-4.9(stat)+/-0.8(syst) Omegab- signal events at a mass of 6.165+/-0.010(stat)+/-0.013(syst) GeV. The significance of the observed signal is 5.4sigma, corresponding to a probability of 6.7 x 10(-8) of it arising from a background fluctuation.

Abstract
Morton-Firth and Bray's stochastic simulator (StochSim) and Gillespie's stochastic simulation algorithm (SSA) are two important methods for stochastic modelling and simulation of biochemical systems. They have been widely applied to different biological problems. A key question is discussed here: Are these two methods equivalent? These two methods are compared using fundamental probability analysis. The analysis clearly shows that, when the time step in the StochSim is chosen very small, the StochSim can be viewed as a first-order approximation to the SSA. The analysis also explains why the SSA is usually much more efficient than the StochSim for biochemical systems. However, when multistate species present in a system, the StochSim clearly shows its advantage. The Complexity analysis is used to explain this advantage. The hybrid SSA (HSSA) is proposed to combine the advantages of both the StochSim and SSA. When the populations of the multistate species are small, the HSSA is very efficient. Numerical experiments are presented to verify the analysis.

Abstract
OBJECTIVE To explore the relationship between Th1/Th2 cytokine expressions and immune tolerance in rat liver transplantation. METHODS Recipients were divided into three groups (each group = 12 rats). The allograft group underwent orthotopic liver transplantation from male Wistar-to-Sprague-Dawley (SD) rats. The isograft group of SD-to-SD liver transplantation was complemented with a control group of normal male SD rats that had sham operations. We evaluated the 2-week survival rates histological changes, as well as serum and mRNA expression levels of Th1/Th2 cytokines: interferon-gamma (IFN-gamma) and interleukin-10 (IL-10). RESULTS The 1-week survival in the isograft and allograft groups were 100% and 41.67%, respectively. The 2-week survival rates were 75% and 8.33% (P < .05). Light microscopic inspection revealed severe acute rejection in the allograft but not the isograft group in the first week postoperation. This observation was verified by the cellular morphology under transmission electron microscopy. Serum IFN-gamma (Th1 cytokine) levels (pg/mL) determined by enzyme-linked immunosorbent assay in the allograft, isograft, and control groups were 386.67 +/- 14.36, 159.83 +/- 16.53, and 87.83 +/- 8.67, respectively; for IL-10 (Th2 cytokine), they were 126.33 +/- 13.10, 288.33 +/- 17.10, and 70.50 +/- 7.23, respectively (P < .05, allograft vs isograft). The semiquantitative reverse-transcriptase polymerase chain reaction assay showed that expression of IFN-gamma and IL-10 mRNA was similar to that of serum levels. IFN-gamma mRNA was more highly expressed in the allograft group and IL-10 mRNA, in the isograft group (P < .05). CONCLUSIONS The dynamic equilibrium of Th1/Th2 cytokines is critically involved in immune tolerance. The deviation of Th1 to Th2 may be one mechanism of immune tolerance.

Abstract
We studied the interactions between human monocytes and porcine endothelial cells (PEC) as well as the effects of a new generation of rabbit anti-human leukocyte polyclonal antibody (newRALG) to inhibit xenogeneic cell-mediated immune responses. Human peripheral blood mononuclear cells (PBMC) were cocultured with the florescent dye PKH-26 labeled-PEC, which showed membrane uptake by monocytes detected by florescence activated cell scanning (FACS). Scavenger receptor (SR) ligand poly-(G) or the newRALG or Thymoglobulin was added into the cocultures followed by FACS. Lymphocyte proliferation upon exposure to PEC with or without newRALG or thymoglobulin was evaluated by a xenogeneic mixed-lymphocyte-endothelial cell reaction (xMLER). FACS analysis demonstrated that CD14+ monocytes became positive for PKH-26 following their interaction with PKH-26-labeled PEC. These PKH-26+ monocytes displayed up-regulated CD40 and CD80 expression during the PBMC-PEC interaction. Furthermore, SR blockade with poly-(G) prevented PEC membrane uptake by CD14+ monocytes. The newRALG from rabbits immunized with activated human monocytes and lymphocytes greatly reduced SR-mediated PEC membrane uptake. xMLER demonstrated strong lymphocyte proliferation in response to PEC. Lymphocyte proliferation was dramatically inhibited in dose-dependent manner by the newRALG. In summary, monocytes up-regulate costimulatory molecules during xenogeneic interactions, indicating that they may serve as a source of T-cell costimulation during xenogeneic reactions, enguling PEC membranes. This phenomenon was inhibited by poly (G), suggesting that PEC membrane uptake was via SR. The newRALG inhibited monocyte SR-mediated PEC membrane uptake and lymphocyte proliferation in response to PEC suggesting that this new polyclonal preparation may impair the initiation of xeno-specific immune responses.

Abstract
This study was designed to examine the role of monocyte-derived CD80 in providing costimulation to CD4+ cells, and to determine whether monocyte-derived CD80 expression is regulated by CD86/CD28 and CD40/CD154 pathways during allogeneic immunoresponses. Human endothelial cells (EC) and purified monocytes cocultured with or without CD4+ cells were analyzed by real-time quantitative polymerase chain reaction (RT-PCR) and florescence-activated cell scanning (FACS). Peripheral blood mononuclear cells (PBMC)-EC cocultures with or without costimulation blockade were analyzed by FACS. The effects of CD154 and CD28 blockade to inhibit lymphocyte proliferation were evaluated by mixed lymphocyte-EC reaction (MLER). RT-PCR demonstrated upregulation of CD80 transcripts in EC-stimulated monocytes in the absence of CD4+ cells. However, the surface expression of CD80 was undetectable. The expression of CD80 was restored in the presence of CD4+ cells. Additionally, CD80 blockade partially inhibited CD4+ cell proliferation induced by EC-conditioned monocytes. Monocytes demonstrated upregulation of CD80 on the surface during PBMC-EC interaction. CD86, CD28, and CD154 blockade did not prevent upregulation of monocyte-derived CD80 expression. CD28 and CD154 blockade partially inhibited lymphocyte proliferation of MLER. In summary, EC-stimulated monocytes upregulated CD80 expression at the transcript level but not on their surface in the absence of T cells. The surface expression of monocyte-derived CD80 is upregulated on EC-stimulated monocytes in the presence of T cells. CD154/CD40 and CD28/CD86 blockade cannot prevent monocyte-derived CD80 expression, suggesting that CD80 upregulation is through a CD154- or CD86-independent pathway. Specific therapy to prevent monocyte activation may be required for successful allograft transplantation.

Abstract
Mammalian sirtuins, Sirt1-Sirt7, are recently discovered regulatory proteins, which play decisive roles in cellular metabolism, stress resistance, and proliferation. Sirtuins are homologs of the founder member of the sirtuin family, the yeast Sir2. Sir2 encodes a NAD(+)-dependent histone deacetylase and its overexpression extends the lifespan through silencing of specific chromatin regions. Lifespan extension by Sir2 homologs was also demonstrated in more complex species such as C. elegans and D. melanogaster. A longevity function has been also postulated for mammalian sirtuins, however definitive proof is still lacking. Here, we have investigated the role of the mouse Sirt7 in the control of cellular growth and proliferation. Using Sirt7 knockout and overexpressing cells we demonstrate an anti-proliferative role of Sirt7. We also show that Sirt7 expression inversely correlates with the tumorigenic potential of several murine cell lines. Considering the known role of Sirt7 as an activator of rDNA transcription we propose that Sirt7 may enable cells to sustain critical metabolic functions by inhibiting cell growth even under severe stress conditions. We conclude, that these Sirt7 functions may improve tissue integrity in aged animals.

Abstract
In 0.9 fb(-1) of pp[over] collisions, the D0 Collaboration presented evidence for single top quark production in events with an isolated lepton, missing transverse momentum, and two to four jets. We examine these data to study the Lorentz structure of the Wtb coupling. The standard model predicts a left-handed vector coupling at the Wtb vertex. The most general lowest dimension, CP-conserving Lagrangian admits right-handed vector and left- or right-handed tensor couplings as well. We find that the data prefer the left-handed vector coupling and set upper limits on the anomalous couplings. These are the first direct constraints on a general Wtb interaction and the first direct limits on left- and right-handed tensor couplings.
