Abstract
BACKGROUND Elevated plasma free fatty acids (FFA) concentration is predictive of the conversion from normal glucose tolerance and impaired glucose tolerance to diabetes. AIMS To evaluate the effects of prolonged exposure to FFA on basal and glucose-stimulated insulin secretion (GSIS) of pancreatic beta-cell, and to investigate the role of oxidative stress in FFA-induced decrease in beta-cell function. METHODS Rats were assigned to 3 groups and underwent 96-h infusions of normal saline (NS), intralipid plus heparin (IH), or intralipid plus heparin and N-acetylcysteine (IH+NAC). The plasma insulin, malonyldialdehyde (MDA), reduced glutathione (GSH), and oxidized glutathione (GSSG) were measured. In vivo intravenous glucose tolerance test (IVGTT) and ex vivo isolated pancreatic tissues perfusion were performed. RESULTS In IH group GSIS both in IVGTT and perifused pancreatic tissues were impaired (p<0.05), the GSH/GSSG ratio was declined and MDA levels increased (p<0.05), the volume density score of nuclear factor kappaB and inducible nitric oxide synthase in pancreatic islets were increased compared to the NS group (p<0.01). In IH+NAC group, NAC intervention partly restored the GSH/GSSG ratio and MDA level, and improved FFA induced GSIS impairment. CONCLUSION Elevated circulating FFA levels may contribute to causing the abnormalities of pancreatic islet cell function through active oxidative stress and oxidative stress-sensitive signaling pathway, which may play a key role in the development of impaired insulin secretion seen in obese Type 2 diabetes.

Abstract
Rheumatoid arthritis (RA) is a common autoimmune disease caused by a complex interaction of multiple genetic variants and environmental factors. The association between RA and genetic susceptibility loci has been observed in many different populations, and most studies have focused on univariate analyses of single nucleotide polymorphisms. We performed a genome-wide haplotype association study and prioritized RA-related genes within 100 kb in either direction of significant haplotypes (P < 0.0001), based on their similarity to known RA susceptibility genes. The results showed that the chemokine CCL3 was associated with susceptibility to RA. A haplotype that located CCL3 on chromosome 17q12 had significant correlation with RA (P = 7.56E-05), and the global similarity score of CCL3 was ranked in the top of all RA-related genes, excluding known susceptibility genes (P = 8.42E-07). Our findings provide further evidence for the potential importance of the chemokine CCL3 in RA, and will facilitate the further understanding of its role in immunological regulation and the pathogenesis of RA.

Abstract
This Letter describes the current most precise measurement of the W boson pair production cross section and most sensitive test of anomalous WWγ and WWZ couplings in pp collisions at a center-of-mass energy of 1.96 TeV. The WW candidates are reconstructed from decays containing two charged leptons and two neutrinos. Using data collected by the CDF II detector from 3.6 fb(-1) of integrated luminosity, a total of 654 candidate events are observed with an expected background of 320±47 events. The measured cross section is σ(pp→W+ W- +X)=12.1±0.9(stat)-1.4+1.6(syst) pb, which is in good agreement with the standard model prediction. The same data sample is used to place constraints on anomalous WWγ and WWZ couplings.

Abstract
PURPOSE To investigate the effect of monitor unit (MU) constraints on the dose distribution created by intensity modulated proton therapy (IMPT) treatment planning using single-field optimization (SFO). METHODS Ninety-four energies between 72.5 and 221.8 MeV are available for scanning beam IMPT delivery at our institution. The minimum and maximum MUs for delivering each pencil beam (spot) are 0.005 and 0.04, respectively. These MU constraints are not considered during optimization by the treatment planning system; spots are converted to deliverable MUs during postprocessing. Treatment plans for delivering uniform doses to rectangular volumes with and without MU constraints were generated for different target doses, spot spacings, spread-out Bragg peak (SOBP) widths, and ranges in a homogeneous phantom. Four prostate cancer patients were planned with and without MU constraints using different spot spacings. Rounding errors were analyzed using an in-house software tool. RESULTS From the phantom study, the authors have found that both the number of spots that have rounding errors and the magnitude of the distortion of the dose distribution from the ideally optimized distribution increases as the field dose, spot spacing, and range decrease and as the SOBP width increases. From our study of patient plans, it is clear that as the spot spacing decreases the rounding error increases, and the dose coverage of the target volume becomes unacceptable for very small spot spacings. CONCLUSIONS Constraints on deliverable MU for each spot could create a significant distortion from the ideally optimized dose distributions for IMPT fields using SFO. To eliminate this problem, the treatment planning system should incorporate the MU constraints in the optimization process and the delivery system should reliably delivery smaller minimum MUs.

Abstract
We report studies of ultrahigh-energy cosmic-ray composition via analysis of depth of air shower maximum (X(max)), for air shower events collected by the High-Resolution Fly's Eye (HiRes) observatory. The HiRes data are consistent with a constant elongation rate d<X(max)>/d[log(E)] of 47.9+/-6.0(stat)+/-3.2(syst) g/cm2/decade for energies between 1.6 and 63 EeV, and are consistent with a predominantly protonic composition of cosmic rays when interpreted via the QGSJET01 and QGSJET-II high-energy hadronic interaction models. These measurements constrain models in which the galactic-to-extragalactic transition is the cause of the energy spectrum ankle at 4x10(18) eV.

Abstract
Our objective was to analyse the clinical characteristics of systemic lupus erythematosus (SLE) patients with gastrointestinal manifestations. Medical charts of 177 hospitalized SLE patients were systematically reviewed, including demographic data, clinical features, laboratory findings, and treatments, as well as outcomes. Thirty-nine cases (22.0%) had SLE-related gastrointestinal manifestations, and in 12 cases (30.8%), gastrointestinal manifestations occurred as the initial symptoms. Twenty-five cases (64.1%) had abdominal pain, 22 cases (56.4%) had nausea and vomiting, 12 cases (30.8%) had diarrhea, and gastrointestinal hemorrhage occurred in three cases (7.7%). Protein losing enteropathy and intestinal pseudo-obstruction were the most common identifiable gastrointestinal complications, though other reasons such as superior mesenteric venous thrombosis, pancreatitis, peritonitis, and liver impairment could also occur in SLE. The incidences of Raynaud's phenomenon and pyeloureterectasis were significantly higher in patients with gastrointestinal complications than those without (p < 0.05). Multivariable analysis indicated Raynaud's phenomenon, decreased C3, CH50, and anti-neutrophil cytoplasmic antibody positivity were independent predictors of gastrointestinal involvements (p < 0.05). Gastrointestinal complications are common, diverse, and could be the initial and major manifestations of lupus. SLE patients who had Raynaud's phenomenon, hypocomplementemia and positive anti-neutrophil cytoplasmic antibody were at increasing risk of developing gastrointestinal complication.

Abstract
The capability to position individual emitters, such as quantum dots, near metallic nanostructures is highly desirable for constructing active optical devices that can manipulate light at the single photon level. The emergence of the field of plasmonics as a means to confine light now introduces a need for high precision and reliability in positioning any source of emission, which has thus far been elusive. Placing an emission source within the influence of plasmonic structures now requires accuracy approaching molecular length scales. In this paper we report the ability to reliably position nanoscale functional objects, specifically quantum dots, with sub-100-nm accuracy, which is several times smaller than the diffraction limit of a quantum dot's emission light. Electron beam lithography-defined masks on metallic surfaces and a series of surface chemical functionalization processes allow the programmed assembly of DNA-linked colloidal quantum dots. The quantum dots are successfully functionalized to areas as small as (100 nm)(2) using the specific binding of thiolated DNA to Au/Ag, and exploiting the streptavidin-biotin interaction. An analysis of the reproducibility of the process for various pattern sizes shows that this technique is potentially scalable to the single quantum dot level with 50 nm accuracy accompanied by a moderate reduction in yield.

Search for the Higgs boson using neural networks in events with missing energy and b-quark jets in pp collisions at square root(s) = 1.96 TeV. PHYSICAL REVIEW LETTERS 2010; 104:141801.

Abstract
We report on a search for the standard model Higgs boson produced in association with a W or Z boson in pp collisions at square root(s)=1.96 TeV recorded by the CDF II experiment at the Tevatron in a data sample corresponding to an integrated luminosity of 2.1 fb(-1). We consider events which have no identified charged leptons, an imbalance in transverse momentum, and two or three jets where at least one jet is consistent with originating from the decay of a b hadron. We find good agreement between data and background predictions. We place 95% confidence level upper limits on the production cross section for several Higgs boson masses ranging from 110 GeV/c(2) to 150 GeV/c(2). For a mass of 115 GeV/c(2) the observed (expected) limit is 6.9 (5.6) times the standard model prediction.
