Abstract
We present a novel synchrotron endstation with a flow-through liquid cell designed to study the electronic structure of liquids using soft x-ray spectroscopies. In this cell, the liquid under study is separated from the vacuum by a thin window membrane, such that the sample liquid can be investigated at ambient pressure. The temperature of the probing volume can be varied in a broad range and with a fast temperature response. The optimized design of the cell significantly reduces the amount of required sample liquid and allows the use of different window membrane types necessary to cover a broad energy range. The liquid cell is integrated into the solid and liquid spectroscopic analysis (SALSA) endstation that includes a high-resolution, high-transmission x-ray spectrometer and a state-of-the-art electron analyzer. The modular design of SALSA also allows the measurement of solid-state samples. The capabilities of the liquid cell and the x-ray spectrometer are demonstrated using a resonant inelastic x-ray scattering map of a 25 wt % NaOD solution.

Abstract
BACKGROUND AND AIM In patients with type 2 diabetes mellitus, the relationship between lowering glycated hemoglobin (HbA(1c)) and macrovascular complications is not clear and therefore lowering the level of HbA(1c) is controversial. METHODS AND RESULTS We searched for all randomized controlled trials comparing the effects of intensive and standard glycemic control on vascular events in patients with type 2 diabetes mellitus. The primary endpoint was combined macrovascular complications, including cardiac events, stroke and peripheral vascular disease. Fixed and random effect models were used to analyze the results. Eight studies were included according to selection criteria. The results showed no benefits of intensive glycemic control on macrovascular and microvascular complications (P>0.1), but a higher rate of severe hypoglycemia (P<0.00001) in the intensive control group when the target HbA(1c) level was <7.0%. When the target HbA(1c) level was lowered to 7.0-7.9%, intensive glycemic control showed benefits on the reduction of microvascular events (P<0.05) without increasing the risk of severe hypoglycemia (P=0.74), but no influence on macrovascular complications (P>0.1). CONCLUSION The results of this analysis suggest that a target HbA(1c) level of 7.0-7.9% may be a better glycemic control target than that of <7.0% in patients with established type 2 diabetes mellitus.

Abstract
In the present study the energetic valorization of electric cable shredder residues (mixed plastics) has been investigated. Thermochemical conversion by means of High-Temperature Steam Gasification (HTSG) and High-Temperature Pyrolysis (HTP) was studied. The effects of temperature and reaction time--process parameters--were investigated. Comparison of the results showed that HTSG seems a more suitable process in terms of produced syngas quality (64%, v/v and 13MJ/Nm(3)) than HTP because of higher H(2) yield and lower tar content.

Abstract
CHARMM (Chemistry at HARvard Molecular Mechanics) is a highly versatile and widely used molecular simulation program. It has been developed over the last three decades with a primary focus on molecules of biological interest, including proteins, peptides, lipids, nucleic acids, carbohydrates, and small molecule ligands, as they occur in solution, crystals, and membrane environments. For the study of such systems, the program provides a large suite of computational tools that include numerous conformational and path sampling methods, free energy estimators, molecular minimization, dynamics, and analysis techniques, and model-building capabilities. The CHARMM program is applicable to problems involving a much broader class of many-particle systems. Calculations with CHARMM can be performed using a number of different energy functions and models, from mixed quantum mechanical-molecular mechanical force fields, to all-atom classical potential energy functions with explicit solvent and various boundary conditions, to implicit solvent and membrane models. The program has been ported to numerous platforms in both serial and parallel architectures. This article provides an overview of the program as it exists today with an emphasis on developments since the publication of the original CHARMM article in 1983.

Abstract
Systemic lupus erythematosus (SLE) is a prototypic autoimmune disease with complex genetic inheritance. Recently, single nucleotide polymorphisms (SNPs) in BANK1 and TNFSF4 have been shown to be associated with SLE in Caucasian populations, but it is not known whether they are also involved in the disease in other ethnic groups. Recent data from our genome-wide association study (GWAS) for 314 SLE cases and 920 controls collected in Hong Kong identified SNPs in and around BANK1 and TNFSF4 to be associated with SLE risk. On the basis of the results of the reported studies and our GWAS, SNPs were selected for further genotyping in 949 SLE patients (overlapping with the 314 cases in our GWAS) and non-overlapping 1042 healthy controls. We confirmed the associations of BANK1 and TNFSF4 with SLE in Chinese (BANK1, rs3733197, odds ratio (OR)=0.84, P=0.021; BANK1, rs17266594, OR=0.61, P=4.67 x 10(-9); TNFSF4, rs844648, OR=1.22, P=2.47 x 10(-3); TNFSF4, rs2205960, OR=1.30, P=2.41 x 10(-4)). Another SNP located in intron 1 of BANK1, rs4522865, was separately replicated by Sequenom in 360 cases and 360 controls and was also confirmed to be associated with SLE (OR=0.725, P=2.93 x 10(-3)). Logistic regression analysis showed that rs3733197 (A383T in ankyrin domain) and rs17266594 (a branch point-site SNP) from BANK1 had independent contributions towards the disease association (P=0.037 and 6.63 x 10(-8), respectively). In TNFSF4, rs2205960 was associated with SLE independently from the effect of rs844648 (P=6.26 x 10(-3)), but not vice versa (P=0.55). These findings suggest that multiple independent genetic variants may be present within the gene locus, which exert their effects on SLE pathogenesis through different mechanisms.

Abstract
622 Background: Evaluation of medical co-morbidities, coordination of reconstructive surgery and referral to tertiary care centers can delay surgical treatment in breast cancer. These delays raise concerns for tumor progression in the interim. We evaluated the time from initial imaging at a cancer center to surgical treatment and the change in tumor size. Methods: We identified 823 patients who underwent surgery as their first therapeutic modality for invasive breast cancer diagnosed from December 2003 to September 2005. Baseline tumor size was determined by mammogram (MMG) and ultrasound (US) reports, and tumor size at surgery was determined by pathology reports. Results: The median time from imaging at our facility to surgery was 0.69 months (range 0.03 to 4.34). Multivariate modeling indicated that older patient age, undergoing total mastectomy, and undergoing reconstruction predicted a longer time from initial imaging to surgery. Comparing radiographic to pathologic size, a moderate correlation was demonstrated for both MMG (Spearman r = 0.58; p < 0.0001) and US (Spearman r = 0.66, p < 0.0001). Pathologic size was the same as MMG size in 14%, smaller in 49%, and larger in 37% of patients. Differences in tumor size estimates were not significantly associated with time lapse between MMG and surgery, but in a multivariate model, MMG tumor size, tumor histology, and tumor grade were significant predictors (p < 0.0001 for all) of differences in mammographic and pathologic size. The pathologic tumor size was the same as US in 10%, smaller in 38%, and larger in 52% of patients. Time lapse to surgery was not significantly associated with differences in US and pathologic tumor size. In a multivariate model, US tumor size (p < 0.0001), tumor histology (p = 0.0006) and tumor grade (p = 0.005) were significant predictors of differences in US and pathologic tumor size estimates. Conclusions: There is no evidence that time lapse from initial imaging to surgical intervention leads to significant changes in tumor size thus allowing patients to complete preoperative workup and planning without significant clinical disease progression.

Abstract
e20675 Background: Prognostic value of comorbidity at diagnosis has received increasing attention. We studied whether the Charlson Comorbidity Index (CMI), Cumulative Illness Rating Scale (CIRS), Kaplan Feinstein Index (KFI), and/or VA Comorbidity Scale (VA) independently predicted survival for NSCLC patients Methods: In an IRB approved protocol, the charts of 101 patients with Stage IIIA, IIIB or IV Non small cell lung cancer seen from 2004 through 2006 at a VA medical center were reviewed of whom 94 have already died. Comorbidity scores ECOG performance status (PS), stage, number of treatments, serum LDH, and albumin levels were obtained or coded from medical records. Survival analyses were performed using proportional hazards models. Results: Median (M) patient age was 69 years (range 51–88), the M ECOG PS was 1 (range 0–4); 13 (13%) had stage IIIA, 27 (26%) IIB and 62 (61%) IV. The M number of treatments was 1 (range 0–6). Histologies were adenocarcinoma in 48 (48%) pts, squamous cell in 37 (37%) pts, and other 17 (15%) pts. The M survival was 207 days (range 4–1785 days). The Median (and ranges) were: 4.2 (1.2–12.8) for CMI, 3 (0–6) for CIRS15, 5(0–11) for CIRS16, 1.8 (0–4) for CIRS17, 0(0–1) for CIRS18, 2 (0–3) for KFI, and 4 (0–8) for VA. The M albumin was 3.7 (range 1.9–5.3) and LDH 201 (range 104–1036). In univariate survival analyses, the stage (p<0.001), ECOG PS (p<0.001), albumin (p<0.003), and the CIRS 17 (p <0.052) were predictive of survival; when, however, bisected by median values, the VA scale (p<0.027), ECOG PS (p<0.052) and albumin (p<.0017) were significantly related to survival but age, LDH, CMI, KFI and subscales of the CIRS (CIRS 16, CIRS 17, CIRS18) were not related to survival. In multivariate proportional hazards analyses that included stage and a comorbidity index, the CIRS16 (p<.032) was an independent predictor of survival; the combinations of stage (p<0.008), ECOG PS (p<.004), stage (p<.006) and albumin (p<.002) were independent predictors of survival. Conclusions: In this small sample, current comorbidity indices did not add to determinations of survival of veterans with advanced NSCLC. Further research is needed in a larger sample.
