Abstract
Using the protein-protein docking program, this study investigates the relationship between TRAF2 and its related proteins and the diversity within the 3D structures of TRAF2s. TRAF2 exists in monomer, trimer, and hexamer forms and it can combine with a number of proteins. Through comparative analysis we found that TRAF2(122), TRAF2(22), TRAF2(21740), TRAF2(2), TRAF2( 22ABC), and TRAF2(Phyre) perform very close homoousia in docking with the same group of ligands, though these TRAF2s come from different sources. The TRAF2-related proteins of cluster 1 change docking values strongly from top to bottom. The TRAF2- related proteins of clusters 2 and 3 have acceptable variation of the docking values. In consideration of the amino acid percentage, TRAF2-related proteins of cluster 2 represent appropriate docking values.

Abstract
Flow coefficients ν(n) for n=2, 3, 4, characterizing the anisotropic collective flow in Au+Au collisions at √s(NN)=200 GeV, are measured relative to event planes Ψ(n), determined at large rapidity. We report ν(n) as a function of transverse momentum and collision centrality, and study the correlations among the event planes of different order n. The ν(n) are well described by hydrodynamic models which employ a Glauber Monte Carlo initial state geometry with fluctuations, providing additional constraining power on the interplay between initial conditions and the effects of viscosity as the system evolves. This new constraint can serve to improve the precision of the extracted shear viscosity to entropy density ratio η/s.

Abstract
Abstract
Background Patients with advanced breast cancer and bone metastases suffer from skeletal complications (SREs, defined as spinal cord compression [SCC], surgery to bone [SB], pathologic fracture [PF] or radiation to bone [RB]). Planning future resource requirements and estimating the value of new treatment options requires prospective data on the health resource burden. However, there is a lack of these data in the literature.
Materials and Methods Patients had bone metastases secondary to advanced breast cancer and were eligible to be included in the study if they had: at least one SRE within 90 days prior to enrolment; life expectancy >6 months; ECOG≤2. HRU (number and length of inpatient hospitalizations, outpatient visits, emergency room visits, number of procedures, etc) associated with SREs was collected retrospectively for 90 days prior to enrolment and prospectively for up to 18–21 months. Attribution of HRU to each SRE was determined independently by the investigators. This pooled European analysis includes data for breast cancer patients from centers in Germany, Italy, Spain and UK.
Results A total of 223 eligible patients with breast cancer and bone metastases were enrolled from the four countries. A total of 118 of 457 SREs (25.8%) were associated with inpatient stays with a mean duration of 18.2 (SD=15.7) days per inpatient stay (for the total 125 stays; a single SRE could contribute multiple hospitalizations). The length of inpatient stays varied by facility (i.e., oncology, radiation, surgical) and SRE type. The most common SRE requiring hospitalization was SB (42 of 54 events [77.8%]) with 45 inpatient stays requiring an average length of stay of 15.1 (SD=16.8) days. The least common SRE requiring hospitalization, RB (27 of 279 events [9.7%]), was still associated with 23 inpatient stays with an average of 16.7 (SD=12.4) days per inpatient stay. A total of 342 SREs (74.8%) required an outpatient visit and 159 (34.8%) required >5 visits. As expected, RB was associated with the highest number of outpatient visits (239 of 279 [85.7%] SREs). SB and PF were associated with fewer outpatient visits with 23 of 54 (42.6%) of 54 SREs and 66 of 105 (62.9%) SREs requiring a visit, respectively. 22 of 457 (4.8%) SREs were associated with an emergency room visit.
Discussion SREs can lead to lengthy hospitalizations and numerous outpatient visits. Neither pain requiring opioid use nor changes in cancer therapy to treat bone pain were reported as SREs, although they may have led to additional inpatient and outpatient visits. Thus, HRU estimated in this study likely underestimates overall HRU associated with SREs in advanced breast cancer patients. Relatively low utilization of emergency room visits reported here may be due to emergency care provided directly by the specialist oncology unit or the patient visiting a different institution. Preventing SREs in advanced breast cancer patients may help to reduce the financial burden to the European healthcare systems.

Abstract
BACKGROUND The facial region has traditionally been quantified using linear anthropometrics. These are well established in dentistry, but require expertise to be used effectively. The aim of this study was to augment the utility of linear anthropometrics by applying them in conjunction with modern 3-D morphometrics. METHODS Facial images of 75 males and 94 females aged 18-25 years with self-reported Caucasian ancestry were used. An anthropometric mask was applied to establish corresponding quasi-landmarks on the images in the dataset. A statistical face-space, encoding shape covariation, was established. The facial median plane was extracted facilitating both manual and automated indication of commonly used midline landmarks. From both indications, facial convexity angles were calculated and compared. The angles were related to the face-space using a regression based pathway enabling the visualization of facial form associated with convexity variation. RESULTS Good agreement between the manual and automated angles was found (Pearson correlation: 0.9478-0.9474, Dahlberg root mean squared error: 1.15°-1.24°). The population mean angle was 166.59°-166.29° (SD 5.09°-5.2°) for males-females. The angle-pathway provided valuable feedback. CONCLUSIONS Linear facial anthropometrics can be extended when used in combination with a face-space derived from 3-D scans and the exploration of property pathways inferred in a statistically verifiable way.

Abstract
Back-to-back hadron pair yields in d+Au and p+p collisions at √s(NN)=200 GeV were measured with the PHENIX detector at the Relativistic Heavy Ion Collider. Rapidity separated hadron pairs were detected with the trigger hadron at pseudorapidity |η|<0.35 and the associated hadron at forward rapidity (deuteron direction, 3.0<η<3.8). Pairs were also detected with both hadrons measured at forward rapidity; in this case, the yield of back-to-back hadron pairs in d+Au collisions with small impact parameters is observed to be suppressed by a factor of 10 relative to p+p collisions. The kinematics of these pairs is expected to probe partons in the Au nucleus with a low fraction x of the nucleon momenta, where the gluon densities rise sharply. The observed suppression as a function of nuclear thickness, p(T), and η points to cold nuclear matter effects arising at high parton densities.

Abstract
Cancer-targeting gene-viro-therapy is a promising cancer therapeutic strategy that strengthens the antitumor effect of oncolytic viruses by expressing an inserted foreign antitumor gene. To achieve liver cancer targeting and to improve the safety of the ZD55 vector (a widely-used E1B55KD gene-deleted oncolytic adenoviral vector (OV), we previously constructed), we designed a novel OV named Ad·AFP·D55 that selectively replicates in hepatocellular carcinoma (HCC) cells by replacing the E1A promoter with the liver-cancer specific α-Fetoprotein (AFP) promoter based on the ZD55 vector. We found that the oncolytic adenoviruses Ad·AFP·D55-IL-24 and Ad·AFP·D55-TRAIL express tumor-suppressor gene interleukin-24 (IL-24) and tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), respectively, significantly suppressed the HCC cell growth in vitro by inducing apoptosis by the caspase-8 and mitochondria-dependent caspase-9 signaling pathways. Furthermore, the combined treatment of Ad·AFP·D55-IL-24 and Ad·AFP·D55-TRAIL showed strong antitumor effects in vivo by significantly inhibiting the tumor growth in HCC HuH-7 cell xenograft mice, and markedly increasing animal survival rate. Therefore, this novel HCC cell-targeting OV carrying tumor-suppressor genes may provide a promising approach for liver cancer gene therapy.

Abstract
We present measurements of J/ψ yields in d+Au collisions at sqrt[s(NN)]=200 GeV recorded by the PHENIX experiment and compare them with yields in p+p collisions at the same energy per nucleon-nucleon collision. The measurements cover a large kinematic range in J/ψ rapidity (-2.2<y<2.4) with high statistical precision and are compared with two theoretical models: one with nuclear shadowing combined with final state breakup and one with coherent gluon saturation effects. In order to remove model dependent systematic uncertainties we also compare the data to a simple geometric model. The forward rapidity data are inconsistent with nuclear modifications that are linear or exponential in the density weighted longitudinal thickness, such as those from the final state breakup of the bound state.

Abstract
Kingella kingae is an emerging pathogen causing osteoarticular infections in pediatric patients. Electron microscopy of K. kingae clinical isolates revealed the heterogeneously-sized membranous structures blebbing from the outer membrane that were classified as outer membrane vesicles (OMVs). OMVs purified from the secreted fraction of a septic arthritis K. kingae isolate were characterized. Among several major proteins, K. kingae OMVs contained virulence factors RtxA toxin and PilC2 pilus adhesin. RtxA was also found secreted as a soluble protein in the extracellular environment indicating that the bacterium may utilize different mechanisms for the toxin delivery. OMVs were shown to be hemolytic and possess some leukotoxic activity while high leukotoxicity was detected in the non-hemolytic OMV-free component of the secreted fraction. OMVs were internalized by human osteoblasts and synovial cells. Upon interaction with OMVs, the cells produced increased levels of human granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin 6 (IL-6) suggesting that these cytokines might be involved in the signaling response of infected joint and bone tissues during natural K. kingae infection. This study is the first report of OMV production by K. kingae and demonstrates that OMVs are a complex virulence factor of the organism causing cytolytic and inflammatory effects on host cells.

Abstract
Engineering proteins for selective tissue targeting can improve therapeutic efficacy and reduce undesired side effects. The relatively high dose of recombinant human acid α-glucosidase (rhGAA) required for enzyme replacement therapy of Pompe disease may be attributed to less than optimal muscle uptake via the cation-independent mannose 6-phosphate receptor (CI-MPR). To improve muscle targeting, Zhu et al. (1) conjugated periodate oxidized rhGAA with bis mannose 6-phosphate bearing synthetic glycans and achieved 5-fold greater potency in a murine Pompe efficacy model. In the current study, we systematically evaluated multiple strategies for conjugation based on a structural homology model of GAA. Glycan derivatives containing succinimide, hydrazide, and aminooxy linkers targeting free cysteine, lysines, and N-linked glycosylation sites on rhGAA were prepared and evaluated in vitro and in vivo. A novel conjugation method using enzymatic oxidation was developed to eliminate side oxidation of methionine. Conjugates derived from periodate oxidized rhGAA still displayed the greatest potency in the murine Pompe model. The efficiency of conjugation and its effect on catalytic activity were consistent with predictions based on the structural model and supported its use in guiding selection of appropriate chemistries.

Abstract
383 Background: This study evaluated rates of trx modifications and reasons for these changes among pts treated with angiogenesis inhibitors in Irish clinical practice. Methods: Data from medical records were retrospectively reviewed at 3 large oncology centers in Ireland for mRCC pts who were ≥ 18 years and received sunitinib (SU) (n=54), sorafenib (n=9), bevacizumab (n=6), or temsirolimus (n=7) as first-line trx from 1/1/2005 to 8/31/2010. Proportions of pts with trx discontinuation (d/c), interruption, or dose change, and reasons for modifications and time to modifications were determined. Results: Due to small sample sizes in other groups, only results for SU are summarized. 1.9% of pts had prior cytokine therapy. Median first-line trx duration for SU was 8.7 months (mo), while median progression-free survival was 13.8 mo. 87% of patients treated with first-line SU experienced adverse events (AEs); 18.5% experienced grade 3/4 AEs. AEs led to trx modifications in 42.6% of pts. 94.4% of pts started trx on 50 mg QD 4/2 dosing; 33.3% of them were dose reduced to 37.5 mg QD 4/2 with median time to reduction 2.7 mo. Among pts who discontinued trx, 31.6% discontinued within 18 weeks (w) (15.8% within 0-6 w, 7.9% in 7-12 w, and 7.9% in 13-18 w). Among pts who discontinued trx within 18 w, 66.7% discontinued due to AEs. Conclusions: Over three-quarters of SU pts experienced trx modifications, more than half due to AEs. About 24% of txt discontinuations occurred within the first two cycles. This real-world practice study suggests that treatment tolerability is a challenge for physicians in the clinical care of mRCC pts. [Table: see text] [Table: see text]

Abstract
ABSTRACTIn order to help establish the role of Cr in high-dose, high-dose-rate, elevated temperature N implantation of austenitic (fcc) stainless steels, similar implantations into fee Ni80Fe20 and Ni80Cr20 alloys have been made and characterized by Auger depth profiling and X-ray diffraction. For the Ni-Fe alloy a shallow layer fcc(∼ 0.2 μm) containing an ordered fee γ'-(Ni0.8Fe0.4)4N phase is induced. In contrast, for the Ni-Cr alloy a much thicker N-containing layer (∼ 0.2 μm) is produced consisting primarily of a high-N solid solution fee phase. The fractions of the implanted N retained in Ni-Fe and Ni-Cr were approximately 10 and 100%, respectively. The mechanisms by which Cr is promoting the deep migration and high retention of N in solid solution are proposed.

Abstract
Large parity-violating longitudinal single-spin asymmetries A(L)(e+) = -0.86(-0.14) (+0.30) and A(L)(e-) = 0.88(-0.71) (+0.12) are observed for inclusive high transverse momentum electrons and positrons in polarized p+p collisions at a center-of-mass energy of sqrt[s] = 500 GeV with the PHENIX detector at RHIC. These e± come mainly from the decay of W± and Z0 bosons, and their asymmetries directly demonstrate parity violation in the couplings of the W± to the light quarks. The observed electron and positron yields were used to estimate W± boson production cross sections for the e± channels of σ(pp → W+ X) × BR(W+ → e+ ν(e)) = 144.1 ± 21.2(stat)(-10.3) (+3.4) (syst) ± 21.6(norm) pb, and σ(pp → W- X) × BR(W- → e- ν[over ¯](e)) = 31.7 ± 12.1(stat)(-8.2) (+10.1) (syst) ± 4.8(norm) pb.

Abstract
Background: Bone metastases are common in women with advanced breast cancer and are frequently associated with skeletal-related events (SREs). The burden of individual SRE types on health resource utilization (HRU) indicators in breast cancer has been only minimally described. Methods: The aim of this ongoing observational, prospective, multinational study is to assess, by tumor type, the amount of HRU associated with different SRE types including pathologic fracture, surgery or radiation to bone, and spinal cord compression. Patients with breast, prostate, or lung cancer and bone metastases or multiple myeloma were enrolled after experiencing a SRE. Inpatient hospitalizations, length of stay, outpatient visits, emergency room visits, nursing home/long-term care facility stays, home health visits, procedures, and medications were collected for the period 90 days prior to enrollment and prospectively to a maximum of 18 months. Each patient could contribute multiple SREs. The investigator determined which HRU were attributed to each SRE. This abstract describes interim analysis data from the US breast cancer cohort; final analysis data will be available 9/2010.
Results: As of 12/1/2009, 67 patients contributed 119 SREs for the HRU analyses across 25 US sites. Patient mean [SD] age was 61 [12] years, all patients were female, and 27% discontinued the study (most due to death). Mean duration of follow-up was 9.9 months. HRU for each of the SRE types are shown in the table.
Table. Mean and median number of HRU per SRE during the study period by SRE type in patients with breast cancer
Conclusion: In this interim analysis of advanced breast cancer patients in the US, SREs are associated with considerable HRU, with the nature and extent of HRU varying depending on the SRE type.

Abstract
We present a solid state nanopore device structure comprising two nanopores which are stacked above each other and connected via a pyramidal cavity of 10 fl volume. The process of fabrication of the pore-cavity-pore device (PCP) relies on the formation of one pore in a Si(3)N(4) membrane by electron beam lithography, while the other pore is chemically etched into the Si carrier by a feedback controlled process. The dimensions of the two nanopores as well as the cavity can be adjusted independently, which is confirmed by transmission electron microscopy. The PCP device is characterized with respect to its electrical properties, including noise analysis and impedance spectroscopy. An equivalent circuit model is identified and resistance, capacitance, and dielectric loss factors are obtained. Potential and electric field distributions inside the electrically biased device are simulated by finite element methods. The low noise characteristics of the PCP device (comparable to a single solid state nanopore) make it suitable for the stochastic sensing of single molecules; moreover, the pore-cavity-pore architecture allows for novel kinds of experiments including the trapping of single nano-objects and single molecule time-of-flight measurements.

Abstract
We have measured the azimuthal anisotropy of π⁰ production for 1<p(T)<18 GeV/c for Au+Au collisions at sqrt((s)NN)=200 GeV. The observed anisotropy shows a gradual decrease for 3≲p(T)≲7-10 GeV/c, but remains positive beyond 10 GeV/c. The magnitude of this anisotropy is underpredicted, up to at least ∼10 GeV/c, by current perturbative QCD (PQCD) energy-loss model calculations. An estimate of the increase in anisotropy expected from initial-geometry modification due to gluon saturation effects and fluctuations is insufficient to account for this discrepancy. Calculations that implement a path-length dependence steeper than what is implied by current PQCD energy-loss models show reasonable agreement with the data.

Abstract
Differential measurements of the elliptic (v(2)) and hexadecapole (v(4)) Fourier flow coefficients are reported for charged hadrons as a function of transverse momentum (p(T)) and collision centrality or number of participant nucleons (N(part)) for Au+Au collisions at sq.rt(s(NN))=200 GeV. The v(2,4) measurements at pseudorapidity |η|≤0.35, obtained with four separate reaction-plane detectors positioned in the range 1.0<|η|<3.9, show good agreement, indicating the absence of significant Δη-dependent nonflow correlations. Sizable values for v(4)(p(T)) are observed with a ratio v(4)(p(T),N(part))/v(2)(2)(p(T),N(part))≈0.8 for 50≲N(part)≲200, which is compatible with the combined effects of a finite viscosity and initial eccentricity fluctuations. For N(part)≳200 this ratio increases up to 1.7 in the most central collisions.

Abstract
Hard-scattered parton probes produced in collisions of large nuclei indicate large partonic energy loss, possibly with collective produced-medium response to the lost energy. We present measurements of π^{0} trigger particles at transverse momenta p{T}{t}=4-12 GeV/c and associated charged hadrons (p{T}{a}=0.5-7 GeV/c) vs relative azimuthal angle Δϕ in Au+Au and p+p collisions at sqrt[s{NN}]=200 GeV. The Au+Au distribution at low p{T}{a}, whose shape has been interpreted as a medium effect, is modified for p{T}{t}<7 GeV/c. At higher p{T}{t}, the data are consistent with unmodified or very weakly modified shapes, even for the lowest measured p{T}{a}, which quantitatively challenges some medium response models. The associated yield of hadrons opposing the trigger particle in Au+Au relative to p+p (I{AA}) is suppressed at high p{T} (I{AA}≈0.35-0.5), but less than for inclusive suppression (R{AA}≈0.2).

Abstract
The scaling properties of jet-suppression measurements are compared for nonphotonic electrons (e+/-) and neutral pions (pi(0)) in Au+Au collisions at sqrt[S(NN)]=200 GeV. For a broad range of transverse momenta and collision centralities, the comparison is consistent with jet quenching dominated by radiative energy loss for both heavy and light partons. Less quenching is indicated for heavy quarks via e+/-; this gives an independent estimate of the transport coefficient q that agrees with its magnitude obtained from quenching of light partons via pi(0)'s.

Abstract
Angiogenesis is a key step in tumor growth and metastasis. The mechanism by which osteopontin (OPN) induces the angiogenesis of endothelial cells remains unclear. Here, we show that OPN confers cytoprotection through the activation of the PI3K/Akt pathway with subsequent upregulation of Bcl-xL and activation of nuclear factor-kappaB. OPN enhances the expression of vascular endothelial growth factor (VEGF) through the phosphorylation of AKT and extracellular signal-regulated kinase (ERK). In turn, OPN-induced VEGF activates PI3K/AKT and the ERK1/2 pathway as a positive feedback signal. Blocking the feedback signal by anti-VEGF antibody, PI3-kinase inhibitor or ERK inhibitor can partially inhibit the OPN-induced human umbilical vein endothelial cell (HUVEC) motility, proliferation and tube formation, while blocking the signal by anti-OPN or anti-alphavbeta3 antibody completely abrogates the biological effects of OPN on HUVECs. In addition, blood vessel formation is also investigated in vivo. The antiangiogenesis efficacy of anti-OPN antibody in vivo is more effective than that of anti-VEGF antibody, which only blocks the feedback signals. These data show that OPN enhances angiogenesis directly through PI3K/AKT- and ERK-mediated pathways with VEGF acting as a positive feedback signal. The results suggest that OPN might be a valuable target for developing novel antiangiogenesis therapy for treatment of cancer.

Abstract
Pulmonary SP‐D is a defence lectin promoting clearance of viral infections. SP‐D is recognized to bind the S protein of SARS‐CoV and enhance phagocytosis. Moreover, systemic SP‐D is widely used as a biomarker of alveolar integrity. We investigated the relation between plasma SP‐D, SARS‐type pneumonia and the SARS‐specific IgG response. Sixteen patients with SARS, 19 patients with community‐acquired pneumonia (CAP) (Streptococcus pneumonia) and 16 healthy control subjects were enrolled in the study. Plasma SP‐D and anti‐SARS‐CoV N protein IgG were measured using ELISA. SP‐D was significantly elevated in SARS‐type pneumonia [median (95% CI), 453 (379–963) ng/ml versus controls 218 (160–362) ng/ml, P < 0.05] like in patients with CAP. SP‐D significantly correlated with anti‐SARS‐CoV N protein IgG (r2 = 0.5995, P = 0.02). The possible re‐emergence of SARS or SARS‐like infections suggests a need for minimal traumatic techniques for following the alveolar compartment, e.g. during testing of antivirals. We suggest that monitoring systemic SP‐D may be useful in monitoring the alveolar integrity in SARS‐type pneumonia. The significant correlation between plasma SP‐D and anti‐SARS‐CoV‐specific antibodies support the role for SP‐D in interlinking innate and adaptive immune pathways.

Abstract
OBJECTIVES The primary objective of this study was to examine the effect of vitamin supplementation on health-related quality of life and the risk of elevated depressive symptoms comparable to major depressive disorder (MDD) in HIV-positive pregnant women in Dar es Salaam, Tanzania. METHODS From April 1995 to July 1997, 1078 HIV-positive pregnant women were enrolled in a randomized controlled trial. We examined the effects of vitamin supplementation on quality of life and the risk of elevated depressive symptoms, assessed longitudinally every 6-12 months. RESULTS A substantial prevalence of elevated depressive symptoms (42%) was observed in HIV-positive pregnant women. Multivitamin supplementation (B-complex, C and E) demonstrated a protective effect on depression [relative risk (RR)=0.78; P=0.005] and quality of life [RR=0.72 for social functioning (P=0.001) and vitality (P=0.0001); RR=0.70 for role-physical (P=0.002)]; however, vitamin A showed no effect on these outcomes. CONCLUSIONS Multivitamin supplementation (B-complex, C and E) resulted in a reduction in risk of elevated depressive symptoms comparable to MDD and improvement in quality of life in HIV-positive pregnant women in Tanzania.

Abstract
Surfactant protein D (SP-D) is a member of the collectin family and is an important component of the pulmonary innate host defence. The protein has a widespread distribution in the human body and is present in multiple epithelia, in endothelium and in blood. Various studies have looked at the relationship between serum SP-D levels and pulmonary inflammatory diseases. The SP-D distribution has been most thoroughly described in European populations and appears with a broad range of serum values highly influenced by genetic factors. In the present study, we investigated the plasma SP-D distribution in a Chinese population from the Tai An region comprising 268 individuals. We found that (i) plasma SP-D in the Chinese population was distributed with a median value of 380.2 ng/ml (324.9; 418.7) and a range from 79.4 to 3965.3 ng/ml, (ii) significantly higher plasma SP-D in men than in women, and no significant effect of age, and (iii) a significant inverse association between serum SP-D and body mass index (BMI) (P = 0.012). The data indicate that racial differences in SP-D expression exist as the median plasma SP-D in the Chinese population was approximately two times lower than the median serum SP-D previously measured in a Danish population using the same immuno-assay. The inverse association between serum SP-D and BMI found in the Chinese population indicates that serum SP-D is related to obesity in similar ways in Chinese and Danes.

Abstract
The proliferation of many pathogenic bacteria is limited by the scarcity of soluble iron in their environment. Many of these bacteria scavenge iron by synthesizing and exporting small molecule siderophores that chelate iron. Iron-bound siderophores are subsequently imported for metabolic processing. Three related serine hydrolases have been characterized biochemically in this pathway: Fes, IroD, and IroE. Here, we report the crystal structure of IroE from uropathogenic Escherichia coli CFT073. The native structure and a complex with diisopropyl fluorophosphonate (DFP, a potent serine hydrolase inhibitor) were determined at 2.3 and 1.4 A resolution, respectively. IroE has the typical alpha/beta-hydrolase fold with an atypical catalytic dyad composed of Ser 189 and His 287. Mutation of either residue was detrimental to catalysis. In addition, rather than the typical oxyanion hole composed of backbone amides, IroE employs the atypical guanidinium moiety of Arg 130. Asp 90 anchors Arg 130 in the active site, and mutation of either residue was likewise detrimental to catalysis. We also compare the structure of IroE to the structure of Fes from Shigella flexneri (PDB entry 2B20). Both enzymes have similar active sites, but Fes has an additional amino-terminal lid domain. These lid domains are proposed to confer specificity to these related hydrolases.

Abstract
This study compared barnidipine, a calcium-channel blocker, and benazepril, an angiotensin-converting enzyme inhibitor, in 85 Chinese patients with renal parenchymal hypertension (diastolic blood pressure range 95 - 110 mmHg). Patients were randomly assigned to receive either 10 mg barnidipine or 10 mg benazepril orally daily for 4 weeks. In patients with diastolic blood pressure > 90 mmHg after 2 weeks of treatment, the dose of barnidipine or benazepril was increased by 5 or 10 mg, respectively. Both the barnidipine-treated group (n = 43) and the benazepril-treated group (n = 42) showed significant mean reductions from baseline in sitting systolic and diastolic blood pressures. The decrease in diastolic blood pressure with benazepril was significantly greater than with barnidipine treatment. Sitting heart rate was not changed by either drug. There was no significant difference in adverse events between the two groups. Barnidipine is similar to benazepril for the treatment of renal parenchymal hypertension.

Abstract
The increased resistance of the glomerulus as a result of contractile dysfunction of mesangial cells (MCs) is associated with reduction of glomerular filtration rate and development of glomerulosclerosis. Evidences show MCs contraction changes with intracellular Ca(2+) concentration ([Ca(2+)](i)). Here, we explore the mechanism of angiotensin II (AngII)-induced Ca(2+) oscillations and MCs contraction. Primary MCs from 3-month-old and 28-month-old rats were used for detection of Ca(2+) oscillations and MC planar area with confocal microscopy. AngII could induce typical Ca(2+) oscillations and contraction of MCs. This process was abolished by thapsigargin, 2-aminoethoxydiphenyl borate, or 1-O-octadecyl-2-O-methyl-sn-glycero-3-phosphorylcholine, and partially inhibited by ryanodine, but could not be inhibited in the absence of extracellular Ca(2+). Ryanodine receptors (RyRs) and inositol 1,4,5-trisphosphate (InsP(3)) receptors displayed a strong colocalization, which may contribute to the amplification of Ca(2+) response. MLC(20) phosphorylation and MC planar area were associated with AngII-induced Ca(2+) oscillations. The frequency of Ca(2+) oscillations was dependent on the AngII concentration and correlated with the MCs' contractive extent, which could be attenuated by KN-93. The amplitude reduction of oscillations correlated with the decrease in aging-related contraction. In conclusion, [Ca(2+)](i) response of MCs to AngII is characterized by repetitive spikes through the following repetitive cycles: Ca(2+) release by phospholipase C -InsP(3) pathway, Ca(2+) amplification by Ca(2+)-activated RyRs and Ca(2+) reuptake by the endoplasmic reticulum. MCs contraction can be modulated by oscillations not only in an AngII-induced frequency-dependent mode but also in an aging-related, amplitude-dependent mode.

Abstract
Infectious agents play a critical role in MALT lymphoma development. Studies from Italy showed Chlamydia psittaci infection in 87% of ocular adnexal MALT lymphomas and complete or partial regression of the lymphoma after C. psittaci eradication in four of nine cases. However, C. psittaci was not demonstrated in ocular adnexal MALT lymphomas from the USA. This study was thus designed to investigate further the role of C. psittaci, and other infectious agents commonly associated with chronic eye disease, in the development of ocular adnexal MALT lymphoma. The presence of C. psittaci, C. trachomatis, C. pneumoniae, herpes simplex virus 1 and 2 (HSV1, HSV2), and adenovirus 8 and 19 (ADV8, ADV19) was assessed separately by polymerase chain reaction in 142 ocular adnexal MALT lymphomas, 53 non-marginal zone lymphomas, and 51 ocular adnexal biopsies without a lymphoproliferative disorder (LPD), from six geographical regions. C. psittaci was detected at similar low frequencies in non-LPD and non-marginal zone lymphoma groups from different geographical regions (0-14%). Overall, the prevalence of C. psittaci was significantly higher in MALT lymphomas (22%) than in non-LPD (10%, p=0.042) and non-marginal zone lymphoma cases (9%, p=0.033). However, the prevalence of C. psittaci infection in MALT lymphoma showed marked variation among the six geographical regions examined, being most frequent in Germany (47%), followed by the East Coast of the USA (35%) and the Netherlands (29%), but relatively low in Italy (13%), the UK (12%), and Southern China (11%). No significant differences in the detection of C. pneumoniae, C. trachomatis, HSV1, HSV2, ADV8, and ADV19 were found between lymphomas and controls from different geographical regions. In conclusion, our results show that C. psittaci, but not C. pneumoniae, C. trachomatis, HSV1, HSV2, ADV8 or ADV19, is associated with ocular adnexal MALT lymphoma and that this association is variable in different geographical areas.

Abstract
HIV integration within host cell genomic DNA is a requisite step of the viral infection cycle. Yet, characteristics of the sites of provirus integration within the host genome remain obscure. The authors present evidence that in diseased tissues showing a high level of HIV DNA and macrophage-associated HIV p24 antigen expression from end stage forms of HIV disease, HIV-1 integration sites were favored within genes and transcriptionally active host cell genomic loci. Using an inverse PCR (IPCR) technique that identified dominant integrated forms of HIV, clonal IPCR products were isolated from AIDS dementia, AIDS lymphoma, and angioimmunoblastic lymphadenopathy tissues. Thirty of 34 disease-associated HIV-1 insertions were identified within annotated and hypothetical genes, an unexpected but highly nonrandom genetic coding region association (p <.026). The 1% sensitivity thresholds used for HIV IPCR suggested some form of selective expansion of cells containing these HIV proviruses. Consistent with this interpretation were the HIV-1 insertion sites identified within introns of genes that encoded for factors associated with signal transduction, apoptosis, and transcription regulation. In addition, HIV-1 proviruses were frequently found proximal to genes that encoded for receptor-associated, signal transduction-associated, transcription-associated, and translation-associated proteins. HIV-1 integration within host cell genomic DNA potentially represents a significant insertional mutagenic event. In certain cases, provirus insertions may mediate the dysregulation of specific gene expression events, providing mechanisms contributing to the pathogenesis associated with certain AIDS-related diseases.

Abstract
Two experiments were conducted to evaluate the NRC (1998) growth model in predicting lysine requirements of high lean gain barrows by using plasma urea nitrogen as a rapid response criterion. In Exp. 1, 20 PIC barrows with an initial BW of 19.1 kg were used to estimate total lysine requirements at approximately 30 and 50 kg of BW in two separate randomized complete block designs. Another set of 20 PIC barrows with an initial BW of 59.0 kg was used to estimate total lysine requirements at about 70, 90, and 110 kg of BW in three separate, completely randomized designs. Pigs were individually penned and had free access to feed and water. Results indicated that total lysine requirements at 33, 52, 72, 93, and 113 kg of BW were 0.96 +/- 0.01, 0.85 +/- 0.02, 0.76 +/- 0.05, 0.66 +/- 0.03, and 0.49 +/- 0.21% of the diet (18.6 +/- 0.2, 20.1 +/- 0.5, 22.6 +/- 1.5, 18.7 +/- 0.8, and 16.8 +/- 7.2 g/d), respectively. The precision of the estimation decreased when pigs reached 70 kg of BW. To increase the precision, Exp. 2 was conducted in which 20 PIC barrows with an initial BW of 45.2 kg were repeatedly used in Latin square designs to estimate total as well as true ileal digestible lysine requirements at BW ranges of from 60 to 80, 80 to 100, and 100 to 120 kg, respectively. During the three BW range periods, the individually penned pigs were limited in feed intake to 2.6, 2.8, and 3.0 kg/d, respectively, and fed once daily. The estimated requirements in the three BW ranges were 21.8 +/- 0.5, 18.8 +/- 0.5, and 20.2 +/- 0.7 g/d in total lysine and 19.9 +/- 0.6, 17.0 +/- 0.5, and 18.1 +/- 0.6 g/d in true ileal digestible lysine, respectively. Total lysine requirements at approximately 30, 50, 70, 90, and 110 kg of BW were about 102, 98, 106, 92, and 99% of the NRC (1998) recommendations, respectively. The close agreement validated the NRC growth model in predicting lysine requirements of high lean gain barrows over the growing-finishing period.

Abstract
PURPOSE Proliferative vitreoretinopathy (PVR) is characterized by the formation of cellular membranes on the detached retina and also in the vitreous. Glial cells can be found in epiretinal and subretinal membranes from eyes with PVR, proliferative diabetic retinopathy (PDR), idiopathic macular pucker, uveitis and other diseases affecting the retina. Proliferation and contraction of glial cells appears to play a role in the pathogenesis of PVR. This study is designed to inspect the effectiveness of harringtonine, as well as colchicine, daunomycin and fluorouracil, against cellular proliferation of cultured human retinal glial cells that might be involved in the retinal and/or vitreous proliferation. METHODS Cultures of human retinal glial cells were prepared using the enzyme digesting method. Cells that had been in culture for 2-5 passages were used in this study. Harringtonine (0.063 microg/ml approximately 2.0 microg/ml), colchicines (0.5 microg/ml approximately 16.0 microg/ml), daunomycin (0.1 microg/ml approximately 3.2 microg/ml) and 5-fluorouracil (0.5 microg/ml approximately 16.0 microg/ml) were added to cultures of human retinal glial cells and the proliferation rates of the cells were measured by the MTT method. RESULTS Harringtonine at the dosage of 0.063 microg/ml induced suppression of cellular growth, but the changes were not statistically significant (p > 0.05). At a dosage ranging from 0.125 microg/ml to 2.0 microg/ml, harringtonine significantly suppressed cellular growth according to the test (p < 0.01). Likewise, other antiproliferative agents inhibited cellular growth significantly at a dosage from 1.0 microg/ml to 16.0 microg/ml (colchicine), 0.2 microg/ml to 3.2 microg/ml (daunomycin) and 1.0 microg/ml to 16.0 microg/ml (5-fluorouracil), but not at 0.5 microg/ml (colchicine), 0.1 microg/ml (daunomycin) and 0.5 microg/ml (5-fluorouracil). The ID50 were 0.33 microg/ml (harringtonine), 3.11 microg/ml (colchicine), 0.79 microg/ml (daunomycin) and 5.23 microg/ml (5-fluorouracil), respectively. CONCLUSIONS Harringtonine was extremely effective in inhibiting human retinal glial cell proliferation, like other antiproliferative drugs such as colchicine, daunomycin and 5-fluorouracil. Harringtonine, therefore, may be a candidate for further studies regarding the treatment of experimental PVR.

Abstract
This study aimed to correlate plasmatic tissue-type plasminogen activator (t-PA) levels and activity with parameters of artery blood flow and vessel walls, nail fold microcirculation, hemorheology, serum glucose, and lipids. Thirty healthy volunteers (female/male 12/18) aged 40-60 (average 46) were included in the study. In citrate venous blood, the following parameters were determined: carotid mean velocity, carotid intimal-medial-thickness (IMT), capillary circulation parameters, hemorheology index, serum glucose, and lipids. Analysis of data showed that t-PA concentration was positively and significantly correlated with total cholesterol, triglycerides, and serum glucose (P<0.05, P<0.05, and P<0.01), but t-PA activity showed no correlation with them; among the hemorheology factors investigated, t-PA concentration showed the strongest positive correlation with both whole blood viscosity and reduced blood viscosity at high and low shear rate separately (P<0.01), t-PA activity showed no correlation with any hemorheology factors; t-PA concentration showed no correlation with any investigated nail fold capillary parameters, whereas t-PA activity was significantly and negatively associated with capillary loop number (P<0.05); t-PA concentration and activity was not associated with values of carotid maximum intimal-medial-thickness (mIMT) and mean velocity or systolic, diastolic blood pressure (P>0.05). But subjects with mIMT 1.0 mm showed higher t-PA levels compared with those with mIMT < 1.0 mm (P<0.05) and decreased carotid mean velocity (P<0.01). These findings suggest that multiple vascular disease risk factors would influence the t-PA level; t-PA concentration does not parallelize with t-PA activity.

Abstract
OBJECTIVE To evaluate the therapeutic effects of gamma-ray stereotactic radiotherapy (SRT) plus whole brain irradiation and radiotherapy alone in brain metastases. METHODS Forty-three patients with brain metastases were treated by SRT plus whole brain irradiation and 50 patients were treated by routine radiotherapy. SRT was given with the dosage of 15-27 Gy, and whole brain irradiation was given with the dosage of 30-40 Gy. RESULTS One-year survival rate, median survival period, and tumor local control rate in SRT plus whole brain irradiation group were higher or longer than those in the routine radiotherapy group (P < 0.01). Mortality in SRT plus whole brain irradiation group was lower than that in the routine radiotherapy group (P < 0.05). CONCLUSION The therapeutic effect of SRT plus whole brain irradiation on brain metastasis of cancer is superior to the routine radiotherapy.

Abstract
The experiment results showed that the best technology of removing the nitrogen was anoxic time to aerobic time of 1:1.5, a cycle of 8 hours; the SRT should be more than 12 d and the loading of NH3-N should be less than 0.063 g/(g.d); when the concentration of CODCr, NH3-N and NOx-N was 1200-1800 mg/L, 135-200 mg/L and 7-10 mg/L respectively, without external carbon sources, the removal rate of NH3-N and TN could respectively achieve 95% and 66%; after adding sodium acetate the removal rate of TN could get to 85%. The addition of sodium acetate at the concentration equivalent to theoretical CODCr values of 125 mg/L appeared to be the most economical and reliable option.

Abstract
BACKGROUND Several different sets of reference body mass index (BMI) values are available to define overweight in children. OBJECTIVE The objective of this study was to compare the prevalence of overweight in US children calculated with 3 sets of reference BMI values: the revised growth charts of the Centers for Disease Control and Prevention (CDC-US growth charts), international standards proposed by Cole et al, and values developed by Must et al. DESIGN Data for children and adolescents came from cross-sectional nationally representative US surveys: cycles II and III of the National Health Examination Survey (1963-1965 and 1966-1970) and the first, second, and third National Health and Nutrition Examination Surveys: NHANES I (1971-1974), II (1976-1980), and III (1988-1994). The reference values of Cole et al equivalent to a BMI of 25 were compared with the 85th percentiles from the other 2 methods; the values equivalent to a BMI of 30 were compared with the 95th percentiles. RESULTS The 3 methods gave similar but not identical results. The reference values of Cole et al gave lower estimates than did the CDC-US growth charts for young children but higher estimates for older children. The reference values of Must et al gave much higher prevalences for younger girls than did the other 2 methods. CONCLUSIONS Differences between methods were related to differences in data sets, smoothing methods, and theoretical approaches. All 3 methods are based on statistical criteria and incorporate arbitrary assumptions. These methods should be used cautiously, with awareness of the possible limitations.

Abstract
The dissipative properties and scaling law for a layer of vertically vibrated granular materials were investigated by means of a dynamical model of a single sphere colliding completely inelastically with a massive, oscillating plate. A relationship is presented of how the temperature of the layer scales with the acceleration of the plate and the restitution coefficient of the grains. The numerical calculation shows the existence of an "energy well" and a "temperature well," which could be used to explain the existence of a f/2 flat (where f is the external driving frequency) state in an experiment on vibrated granular material.

Abstract
Changes in cell number (hyperplasia) and cell size (hypertrophy) in the brain and liver are described for mice subjected to 24 generations of age-specific restricted index selection for rate of development in body weight. One selection treatment (E) altered rate of development between birth and 10 days of age, another treatment (L) involved changes in rate of development between 28 and 56 days of age, while a third control treatment (C) involved random selection. Each selection treatment was replicated three times. These age-specific selection treatments focused on intervals during ontogeny when different developmental processes (hypertrophy or hyperplasia) were more predominant in the control of growth. Significant changes in brain and liver weight occurred at both 28 and 70 days of age. Early selection (E) generated significant changes in the number of cells in the brain while later selection (L) had no effect since the brain had stopped growth before selection was initiated. For the liver, early and late selection produced significant effects on both cell number and cell size. These results describe the dynamic and multidimensional aspects of selection in terms of its ability to alter different cellular and developmental components of complex morphological traits.

Abstract
OBJECTIVES This report presents the revised growth charts for the United States. It summarizes the history of the 1977 National Center for Health Statistics (NCHS) growth charts, reasons for the revision, data sources and statistical procedures used, and major features of the revised charts. METHODS Data from five national health examination surveys collected from 1963 to 1994 and five supplementary data sources were combined to establish an analytic growth chart data set. A variety of statistical procedures were used to produce smoothed percentile curves for infants (from birth to 36 months) and older children (from 2 to 20 years), using a two-stage approach. Initial curve smoothing for selected major percentiles was accomplished with various parametric and nonparametric procedures. In the second stage, a normalization procedure was used to generate z-scores that closely match the smoothed percentile curves. RESULTS The 14 NCHS growth charts were revised and new body mass index-for-age (BMI-for-age) charts were created for boys and girls (http://www.cdc.gov/growthcharts). The growth percentile curves for infants and children are based primarily on national survey data. Use of national data ensures a smooth transition from the charts for infants to those for older children. These data better represent the racial/ethnic diversity and the size and growth patterns of combined breast- and formula-fed infants in the United States. New features include addition of the 3rd and 97th percentiles for all charts and extension of all charts for children and adolescents to age 20 years. CONCLUSION Created with improved data and statistical curve smoothing procedures, the United States growth charts represent an enhanced instrument to evaluate the size and growth of infants and children.

Abstract
OBJECTIVE To study the safety and effectiveness of phacoemulsification (phaco) in trabeculectomy combined with cataract extraction (phacotrabeculectomy) and posterior chamber intraocular lens (IOL) implantation. METHODS 68 eyes with glaucoma and cataract were randomly divided into two groups: the phacotrabeculectomy with IOL implantation and modern extracapsular cataract extraction (ECCE), trabeculectomy and IOL implantation. RESULTS Postoperatively, in the phaco group, the intraocular pressure (IOP) decreased obviously at the early stage (P < 0.05), the number of cases necessary for the use of anti-glaucoma drug was decreased, the mean kinds of the drug applied were markedly decreased (P < 0.05), the visual acuity improved quickly, significantly and steadily, and the complications were less than that in the ECCE group. CONCLUSIONS The phaco's triple surgery is safe and effective. In cases with glaucoma and cataract, the surgery is indicated even when the cataract is not mature or premature.
