Abstract
Aim: This study was to investigate the change of high-molecula-weight (HMW) adiponectin (APN) isoform, the association between type 2 diabetes mellitus (T2DM) and HMW APN isoform, the variation of Disulfide-bond A oxidoreductase-like protein (DsbA-L), the effect of HMW APN isoform on AMP-dependent protein kinase (AMPK) and endothelial nitric oxide synthase (eNOS) in Chinese T2DM. Method: 169 patients aged at (48.7±9.4) years and 107 healthy control subjects aged at (42.6±7.8) years took part in this study. Anthropometric measures of the characters were assayed and different APN isoforms, DsbA-L, AMPK and eNOS levels were determined. Results: Ln(sRAGE) and Ln(Adiponectin) were significantly lower and significantly higher for the other characteristics in T2DM. Ln(Adiponectin) was negatively and significantly correlated with WHR, Ln(triglycerides), fasting plasma glucose, HbA1c (%) in control subjects and T2DM patients. Plasma and adipose tissue total APN and HMW APN were significantly reduced in newly diagnosed T2DM patients. DsbA-L was markedly down-regulated in diabetic adipose tissue. HMW APN caused significant decreases in AMPK and eNOS phosphorylation levels of human umbilical vein endothelial cells (HUVECs). Conclusions: Our results demonstrated that total APN levels was closely related to the risk of T2DM and HMW APN reduction was involved in the diabetic vascular AMPK/eNOS signal pathway. The findings will provide insight into novel therapeutic approaches for reducing the elevated cardiovascular risk associated with T2DM.

Abstract
Background Although patients with kidney disease have potential to benefit from revascularization, they are also at higher risk of complications, which may affect quality of life. Methods and Results We studied a cohort of 8198 adults who underwent coronary angiography in Alberta, between 2004 and 2008, and completed health‐related quality‐of‐life (HR‐QOL) surveys. Changes in HR‐QOL measures were most favorable among patients who received coronary artery bypass graft (CABG), but did not significantly differ by kidney function within groups of patients who received CABG, percutaneous coronary intervention (PCI), or medical therapy (P value for interaction between estimated glomerular filtration rate [eGFR] and revascularization status >0.10 for all outcomes). Among those who received CABG, the adjusted mean EuroQol 5 dimensions (EQ‐5D) utility score for those with eGFR >90 mL/min per 1.73 m2 increased by 0.11 (95% CI, 0.09–0.14) and for those with eGFR <30 mL/min per 1.73m2 by 0.13 (95% CI, 0.05–0.21). The adjusted mean EQ‐5D utility score also increased similarly at all levels of eGFR for those who received PCI and for those who received medical management. Mean changes in Seattle Angina Questionnaire (SAQ) scores were also similar across all levels of eGFR within each treatment group for the quality of life, angina frequency, angina stability, physical limitations, and treatment satisfaction domains of the SAQ. Among those who received CABG, the adjusted mean SAQ quality of life score for those with eGFR >90 mL/min per 1.73m2 increased by 22.1 (95% CI, 18.5–25.7) and for those with eGFR <30 mL/min per 1.73m2 by 14.0 (95% CI, 2.31–25.63). Conclusions Changes in HR‐QOL do not vary by kidney function among patients selected for CABG, PCI, or medical management of coronary disease.

Abstract
Polypharmacology, the process in which a single drug is able to bind to multiple targets specifically and simultaneously, is an emerging paradigm in drug development. The potency of a given drug can be increased through the engagement of multiple targets involved in a certain disease. Polypharmacology may also help identify novel applications of existing drugs through drug repositioning. However, many problems and challenges remain in this field. Rather than covering all aspects of polypharmacology, this Minireview is focused primarily on recently reported techniques, from bioinformatics technologies to cheminformatics approaches as well as text-mining-based methods, all of which have made significant contributions to the research of polypharmacology.

Abstract
Despite the pollution of microplastics being internationally recognized, the understanding of their behaviors in marine environment is still developing. Microplastics are ubiquitous in the marine environment, with the potential to cause harm to marine ecosystem. Here, we would classify the behaviors of microplastics as physical behaviors (i.e. migration, sedimentation and accumulation), chemical behaviors (i.e. degradation and adsorption) and biobehaviors (i.e. ingestion, translocation and biodegradation), and a further discussion on their behavioral mechanisms were presented to better understand their impacts for the marine environment.

Abstract
Despite the high mortality from metastatic cancer, therapeutic targets to prevent metastasis are limited. Efforts to identify genetic aberrations that predispose tumors to metastasis have been mostly unsuccessful. To understand the nature of candidate targets for metastatic disease, we performed an in silico screen to identify drugs that can inhibit a gene expression signature associated with epithelial-mesenchymal transition (EMT). Compounds discovered through this method, including those previously identified, appeared to restrict metastatic capacity through a common mechanism, the ability to modulate the fluidity of cell membranes. Treatment of breast cancer cell lines with the putative antimetastasis agents reduced membrane fluidity, resulting in decreased cell motility, stem cell-like properties, and EMT in vitro, and the drugs also inhibited spontaneous metastasis in vivo When fluidity was unchanged, the antimetastasis compounds could no longer restrict metastasis, indicating a causal association between fluidity and metastasis. We further demonstrate that fluidity can be regulated by cellular cholesterol flux, as the cholesterol efflux channel ABCA1 potentiated metastatic behaviors in vitro and in vivo The requirement for fluidity was further supported by the finding in breast cancer patients that ABCA1 was overexpressed in 41% of metastatic tumors, reducing time to metastasis by 9 years. Collectively, our findings reveal increased membrane fluidity as a necessary cellular feature of metastatic potential that can be controlled by many currently available drugs, offering a viable therapeutic opportunity to prevent cancer metastasis.

Abstract
Background Ribosomal protein S6 (rpS6), a component of the 40S ribosomal subunit, is involved in multiple cellular bioactivities. However, its clinicopathological significance in non-small cell lung cancer (NSCLC) is poorly understood. Methods Expressions of total rpS6 (t-rpS6) and phosphorylated rpS6 (Ser235/236, p-rpS6) were detected immunohistochemically in 316 NSCLC tissues and 82 adjacent controls, followed by statistical evaluation of the relationship between proteins expressions and patients’ survivals to identify their prognostic values. Cytological experiments with overexpressing or silencing rpS6 by lentivirus in human bronchial epithelial (HBE) and NSCLC cell lines were performed to explore potential mechanisms by which rpS6 affects the clinical development of NSCLC. Additionally, specific RNA interference for Akt1, Akt2, Akt3, Akt inhibitor and subsequent cellular bioactivity tests were employed as well to investigate the upstream regulation of rpS6. Results Positive rates of t-rpS6 and p-rpS6 were both significantly increased in NSCLC tissues, compared with controls (82.91 vs 62.20 % for t-rpS6; 52.22 vs 21.95 % for p-rpS6; both P < 0.001). However, only hyperphosphorylation of rpS6, expressed as either elevated p-rpS6 alone or the ratio of p-rpS6 to t-rpS6 (p-rpS6/t-rpS6) no less than 0.67, was greatly associated with the unfavorable survival of NSCLC patients, especially for cases at stage I (all P < 0.001). The independent adverse prognostic value of hyperphosphorylated rpS6 was confirmed by multivariate Cox regression analysis (hazard ratios for elevated p-rpS6 alone and p-rpS6/t-rpS6 no less than 0.67 were 2.403, 4.311 respectively, both P < 0.001). Overexpression or knockdown of rpS6, along with parallel alterations of p-rpS6, led to increased or decreased cells proliferations respectively, which were dependent on redistributions of cell cycles (all P < 0.05). Cells migration and invasion also changed with rpS6 interference (all P < 0.05). Furthermore, upstream overexpression or knockdown of Akt2 or Akt2 phosphorylation inhibition, rather than Akt1 or Akt3, resulted in striking hyperphosphorylation or dephosphorylation of mTOR, p70S6K and rpS6 (all P < 0.05), without any change in total proteins expressions. Further tests showed markedly accompanied variation of cells proliferation, cell cycle distribution and invasion (all P < 0.05). Conclusion Hyperphosphorylation of rpS6, probably regulated by the Akt2/mTOR/p70S6K signaling pathway, is closely relevant to the progression of NSCLC and it might be served as a promising therapeutic target for NSCLC treatment.

Abstract
The novel regulation mechanism in mtDNA-less cells was investigated. Very low mtDNA copy in mtDNA-less 206 ρ° cells was identified. But no 13 mitochondria-specific proteins were translated in 206 ρ° cells. Their mitochondrial respiration complexes V, III and II were 86.5, 29.4 and 49.6% of 143B cells, respectively. Complexes I and IV completely lack in 206 ρ° cells. Non-mitochondrial respiration to generate ATP in 206 ρ° cells was discovered. The expression levels of some mitochondrial RNAs including 12S rRNA, COX1, COX2, COX3, ND4 and ND5 were low. However, ND1, ND3 and Cyto b were not expressed in 206 ρ° cells. Unequal transcription of mitochondrial RNAs indicated the post-transcriptional cleavage and processing mechanisms in the regulation of mitochondrial gene expression in 206 ρ° cells. MicroRNAs (miRNAs) may modulate these mitochondrial RNA expression in these cells. RNA-induced silencing complex indeed within 206 ρ° cell mitochondria indicated miRNAs in 206 ρ° cell mitochondria. miRNA profile in mtDNA-less 206 ρ° cells was studied by next-generation sequencing of small RNAs. Several mitochondria-enriched miRNAs such as miR-181c-5p and miR-146a-5p were identified in 206 ρ° cell mitochondria. miR-181c-5p and miR-146a-5p had 23 and 19 potential targets on mitochondrial RNAs respectively, and these two miRNAs had multiple targets on mitochondria-associated messenger RNAs encoded by nuclear genes. These data provided the first direct evidence that miRNAs were imported into mitochondria and regulated mitochondrial RNA expressions.

Abstract
Total knee replacement (TKR) is an effective method of treating end-stage arthritis of the knee. It is not, however, a procedure without risk due to a number of factors, one of which is diabetes mellitus. The purpose of this study was to estimate the general prevalence of diabetes in patients about to undergo primary TKR and to determine whether diabetes mellitus adversely affects the outcome. We conducted a systematic review and meta-analysis according to the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines. The Odds Ratio (OR) and mean difference (MD) were used to represent the estimate of risk of a specific outcome. Our results showed the prevalence of diabetes mellitus among patients undergoing TKR was 12.2%. Patients with diabetes mellitus had an increased risk of deep infection (OR = 1.61, 95% confidence interval (CI), 1.38 to 1.88), deep vein thrombosis (in Asia, OR = 2.57, 95% CI, 1.58 to 4.20), periprosthetic fracture (OR = 1.89, 95% CI, 1.04 to 3.45), aseptic loosening (OR = 9.36, 95% CI, 4.63 to 18.90), and a poorer Knee Society function subscore (MD = -5.86, 95% CI, -10.27 to -1.46). Surgeons should advise patients specifically about these increased risks when obtaining informed consent and be meticulous about their peri-operative care.

Abstract
BACKGROUND AND OBJECTIVES AKI after coronary angiography is associated with poor long-term outcomes. The relationship between contrast-associated AKI and subsequent use of prognosis-modifying cardiovascular medications is unknown. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A cohort study of 5911 participants 66 years of age or older with acute coronary syndrome who received a coronary angiogram in Alberta, Canada was performed between November 1, 2002, and November 30, 2008. AKI was identified according to Kidney Disease Improving Global Outcomes AKI criteria. RESULTS In multivariable logistic regression models, compared with participants without AKI, those with stages 1 and 2-3 AKI had lower odds of subsequent use of angiotensin-converting enzyme inhibitors/angiotensin receptor blocker within 120 days of hospital discharge (adjusted odds ratio, 0.65; 95% confidence interval, 0.53 to 0.80 and odds ratio, 0.34; 95% confidence interval, 0.23 to 0.48, respectively). Subsequent statin and β-blockers use within 120 days of hospital discharge was significantly lower among those with stages 2-3 AKI (adjusted odds ratio, 0.44; 95% confidence interval, 0.31 to 0.64 and odds ratio, 0.46; 95% confidence interval, 0.31 to 0.66, respectively). These associations were consistently seen in patients with diabetes mellitus, heart failure, low baseline eGFR, and albuminuria; 952 participants died during subsequent follow-up after hospital discharge (mean=3.1 years). The use of each class of cardiovascular medication was associated with lower mortality, including among those who had experienced AKI. CONCLUSIONS Strategies to optimize the use of cardiac medications in people with AKI after coronary angiography might improve care.

Abstract
![]()
In
drug discovery and development, the conventional “single drug,
single target” concept has been shifted to “single drug,
multiple targets” – a concept coined as polypharmacology.
For studies in this emerging field, dedicated and high-quality databases
of multitargeting ligands would be exceedingly beneficial. To this
end, we conducted a comprehensive analysis of the structural and chemical/biological
profiles of polypharmacological agents and present a Web-based database
(Polypharma). All of these compounds curated herein
have been cocrystallized with more than one unique protein with intensive
reports of their multitargeting activities. The present study provides
more insight of drug multitargeting and is particularly useful for
polypharmacology modeling. This specialized curation has been made
publically available at http:/imdlab.org/polypharma/

Abstract
Deep venous thrombosis (DVT) is a common surgical complication in cancer patients and
evidence that inflammation plays a role in the occurrence of DVT is increasing. We
studied a population of cancer patients with abdominal malignancies with the aim of
investigating whether the levels of circulating inflammatory cytokines were
associated with postoperative DVT, and to determine the levels in DVT diagnoses. The
serum levels of C-reactive protein (CRP), interleukins (IL)-6 and IL-10, nuclear
transcription factor-κB (NF-κB) and E-selectin (E-Sel) were determined in 120
individuals, who were divided into 3 groups: healthy controls, patients with and
patients without DVT after surgery for an abdominal malignancy. Data were analyzed by
ANOVA, Dunnet's T3 test, chi-square test, and univariate and multivariate logistic
regression as needed. The CRP, IL-6, NF-κB, and E-Sel levels in patients with DVT
were significantly higher than those in the other groups (P<0.05). The IL-10 level
was higher in patients with DVT than in controls but lower than in patients without
DVT. Univariate analysis revealed that CRP, IL-6, NF-κB, and E-Sel were statistically
associated with the risk of DVT (OR=1.98, P=0.002; OR=1.17, P=0.000; OR=1.03,
P=0.042; and OR=1.38, P=0.003; respectively), whereas IL-10 had a protective effect
(OR=0.94, P=0.011). Multivariate analysis showed that E-Sel was an independent risk
factor (OR=1.41, P=0.000). Thus, this study indicated that an increased serum level
of E-Sel was associated with increased DVT risk in postoperative patients with
abdominal malignancy, indicating that E-Sel may be a useful predictor of diagnosis of
DVT.

Abstract
Chronic rejection that leads to diffuse narrowing and occlusion of graft vessels is the most important cause of morbidity and mortality following cardiac transplantation. The role and underlying mechanism of high-mobility group box 1 (HMGB1), as an established inflammatory mediator in acute rejection, remains poorly understood in chronic rejection. Here, we assessed the effects and mechanisms of HMGB1 on the chronic rejection using single MHC Class II-mismatched mouse cardiac transplantation model. It was found that HMGB1 was increased accompanying with the development of chronic rejection, while blockade of HMGB1 with specific neutralizing mAb substantially ameliorated chronic rejection-mediated vasculopathy and fibrosis of allograft, as well as markedly decreased T cell infiltration and production of IL-17A and interferon-gamma in allograft and recipient's spleen. Further, anti-HMGB1 antibody treatment significantly declined the number and frequency of mature dendritic cells (DCs) in allograft and recipient's spleen, especially CD11b(+) Ly6C(high) matured DCs that share the phenotypes with inflammatory-DCs. These findings indicate that HMGB1 contributes to chronic rejection, and HMGB1 blockade may be a novel mean to disrupt the proinflammatory loop after heart transplantation.

Abstract
OBJECTIVES Many studies have demonstrated that the clock gene, brain and muscle ARNT-like 1 (Bmal1), is directly related to bone ageing by affecting age-related changes to mesenchymal stem cells (MSCs). As a main developmental signal, Wnt may play an important role in this process. Here, we have aimed to elucidate whether Bmal1 positively regulates osteogenesi via Wnt pathways. MATERIALS AND METHODS Bone marrow stromal cells were cultured in basic and in osteo-induction medium with Wnt signalling inhibitor Dkk1 and Bmal1 transfection. Proliferation and osteogenesis of MSCs, expression of Bmal1 and activation of Wnt signalling were investigated by flow cytometry, senescence-associated β-galactosidase (SA-β-gal) staining, real-time quantitative PCR and western blot analysis. RESULTS Expression of Bmal1 (specially after 7 days osteo-induction), activation of Wnt signalling and osteo-related factors fell significantly during osteo-induction after Dkk1 addition. When cellular Bmal1 was increased by transfection, osteogenesis inhibition by Dkk1 was rescued to a certain extent with activation of Wnt signalling. However, Dkk1 did not significantly affect proliferation or senescence of MSCs during early periods of culture. CONCLUSION These findings demonstrated that Bmal1 and Wnt signalling may have a synergistic effect at a particular stage of osteogenesis. Inhibition of Wnt signalling did not greatly affect ageing of MSCs through early passages.

Abstract
BACKGROUND AND OBJECTIVES Although patients with ESRD have a higher fracture risk than the general population, there is conflicting evidence regarding fracture incidence in those with CKD. This study sought to determine the association between estimated GFR (eGFR) and fracture rates. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This study identified 1,815,943 community-dwelling adults who had at least one outpatient serum creatinine measurement between 2002 and 2008. Patients with eGFR <15 ml/min per 1.73 m(2) and those who required dialysis were excluded. Incident fractures of the hip, wrist, and vertebrae were identified using diagnostic and procedure codes. Poisson regression was used to determine adjusted rates of each fracture type by eGFR, age, and sex. RESULTS The median age of the cohort was 47 years (interquartile range, 24), and 7.1% had eGFR <60 ml/min per 1.73 m(2). Over a median follow-up of 4.4 years, fracture rates increased with age at all sites. Within each age stratum, unadjusted rates increased with declining eGFR; however, adjusted rates were similar across eGFR categories. For example, among women aged 65-74 years, adjusted hip fracture rates were 3.41 per 1000 person-years (95% confidence interval, 2.30 to 4.53) and 4.58 per 1000 person-years (95% confidence interval, 0.02 to 9.14) in those with eGFR ≥90 and 15-29 ml/min per 1.73 m(2), respectively. Similar results were observed for wrist and vertebral fractures. CONCLUSIONS In contrast to earlier studies, patients with eGFR<60 ml/min per 1.73 m(2) do not appear to have increased rates of hip, wrist, and vertebral fractures independent of age and sex.

Abstract
The murine heterotopic intestinal transplant model is of particular value for addressing the unique immune response in the gut and addressing the underlying immune mechanism during transplantation. Anastomotic stenosis, anastomotic bleeding, and septic shock continue to hamper procedures and plague the success. In this study, we assessed a refined technique designed to improve the success of heterotopic intestinal transplant in mice. Important factors in our refined technique included (1) a refined procedure for graft portal vein preparation, (2) a novel procedure for graft exteriorization, and most importantly (3) a knotless suturing technique designed to allow the surgeon to alter the size of the anastomosis, thus reducing anastomotic bleeding and stenosis rate. Our refined knotless method improved recipient survival to 67.5% when compared to the standard technique (53.8%). In comparison to standard knot suturing technique, which had an anastomotic stenosis rate of 8.3%, the knotless suturing technique significantly reduced the rate of anastomotic stenosis to only 2.4%. Anastomotic bleeding presented in the knotless technique in only 1.2%, whereas it presented in 6.2%, of mice in the standard technique (P < .05). This refined knotless technique offers an easy and effective method for murine heterotopic intestinal transplantation.

Abstract
The mechanisms of progesterone on endothelial cell motility are poorly investigated. Previously we showed that progesterone stimulated endothelial cell migration via the activation of actin-binding protein moesin, leading to actin cytoskeleton remodelling and the formation of cell membrane structures required for cell movement. In this study, we investigated the effects of progesterone on the formation of focal adhesion complexes, which provide anchoring sites for cell movement. In cultured human umbilical endothelial cells, progesterone enhanced focal adhesion kinase (FAK) phosphorylation at Tyr397 in a dose- and time-dependent manner. Several signalling inhibitors interfered with progesterone-induced FAK activation, including progesterone receptor (PR) antagonist ORG 31710, specific c-Src kinase inhibitor PP2, phosphatidylinosital-3 kinase (PI3K) inhibitor wortmannin as well as ρ-associated kinase (ROCK-2) inhibitor Y27632. It suggested that PR, c-Src, PI3K and ROCK-2 are implicated in this action. In line with this, we found that progesterone rapidly promoted c-Src/PI3K/Akt activity, which activated the small GTPase RhoA/ρ-associated kinase (ROCK-2) complex, resulting in FAK phosphorylation. In the presence of progesterone, endothelial cells displayed enhanced horizontal migration, which was reversed by small interfering RNAs abrogating FAK expression. In conclusion, progesterone promotes endothelial cell movement via the rapid regulation of FAK. These findings provide new information on the biological actions of progesterone on human endothelial cells that are relevant for vascular function.

Abstract
CONTEXT Studies of kidney failure in older adults have focused on receipt of dialysis, which may underestimate the burden of disease if older people are less likely to receive treatment. OBJECTIVE To determine the extent to which age is associated with the likelihood of treatment of kidney failure. DESIGN, SETTING, AND PARTICIPANTS Community-based cohort study of 1,816,824 adults in Alberta, Canada, who had outpatient estimated glomerular filtration rate (eGFR) measured between May 1, 2002, and March 31, 2008, with a baseline eGFR of 15 mL/min/1.73 m2 or higher and who did not require renal replacement therapy at baseline. Age was categorized as 18 to 44, 45 to 54, 55 to 64, 65 to 74, 75 to 84, and 85 or more years and eGFR as 90 or higher, 60 to 89, 45 to 59, 30 to 44, and 15 to 29 mL/min/1.73 m2. MAIN OUTCOME MEASURES Adjusted rates of treated kidney failure (receipt of dialysis or kidney transplantation), untreated kidney failure (progression to eGFR <15 mL/min/1.73 m2 without renal replacement therapy), and death. RESULTS During a median follow-up of 4.4 years, 97,451 (5.36%) died, 3295 (0.18%) developed kidney failure that was treated and 3116 (0.17%) developed kidney failure that went untreated. Within each eGFR stratum the rate of treated kidney failure was higher in younger compared with older people. For example, in the lowest eGFR stratum (15-29 mL/min/1.73 m2), adjusted rates of treated kidney failure were more than 10-fold higher among the youngest (18-44 years) compared with the oldest (≥85 years) groups (adjusted rate, 24.00 [95% CI, 14.78-38.97] vs 1.53 [95% CI, 0.59-3.99] per 1000 person-years, respectively; P < .001). Rates of untreated kidney failure were consistently higher at older ages. In the eGFR stratum of 15 to 29 mL/min/1.73 m2, adjusted rates of untreated kidney failure were more than 5-fold higher among the oldest (≥85 years), compared with the youngest (18-44 years) groups (adjusted rate, 19.95 [95% CI, 15.79-25.19] vs 3.53 [95% CI, 1.56-8.01] per 1000 person-years, respectively; P < .001). Rates of kidney failure overall (treated and untreated combined) demonstrated less variation across age groups; eg, the adjusted rate per 1000 person years for those with eGFR of 15-29 mL/min/1.73 m2 was 36.45 (95% CI, 24.46-54.32) among participants aged 18 to 44 years and 20.19 (95% CI, 15.27-26.69) among those aged 85 years or older (P = .01). CONCLUSION In Alberta, Canada, rates of untreated kidney failure are significantly higher in older compared with younger individuals.

Abstract
PURPOSE To model X-ray coherent scatter diffraction patterns in GEANT4 for simulating experiments involving material detection through diffraction pattern measurement. Although coherent scatter cross-sections are modeled accurately in GEANT4, diffraction patterns for crystalline materials are not yet included. Here we describe our modeling of crystalline diffraction patterns in GEANT4 for specific materials and the validation of the results against experimentally measured data. METHODS Coherent scatter in GEANT4 is currently based on Hubbell's non-relativistic form factor tabulations from EPDL97. We modified the form-factors by introducing an interference function that accounts for the angular dependence between the Rayleigh-scattered photons and the photon wavelength. The modified form factors were used to replace the inherent form-factors in GEANT4. The simulation was tested using monochromatic and polychromatic x-ray beams (separately) incident on objects containing one or more elements with modified form-factors. The simulation results were compared against the experimentally measured diffraction images of corresponding objects using an in-house x-ray diffraction imager for validation. The comparison was made using the following metrics: number of diffraction rings, radial distance, absolute intensity, and relative intensity. RESULTS Sharp diffraction pattern rings were observed in the monochromatic simulations at locations consistent with the angular dependence of the photon wavelength. In the polychromatic simulations, the diffraction patterns exhibited a radial blur consistent with the energy spread of the polychromatic spectrum. The simulated and experimentally measured patterns showed identical numbers of rings with close agreement in radial distance, absolute and relative intensities (barring statistical fluctuations). No significant change was observed in the execution time of the simulations. CONCLUSIONS This work demonstrates the ability to model coherent scatter diffraction in GEANT4 in an accurate and efficient manner without compromising the accuracy or runtime of the simulation.

Abstract
Insulin resistance is recognized as a common metabolic factor which predicts the future development of both type 2 diabetes and atherosclerotic disease. Resveratrol (RSV), an agonist of estrogen receptor (ER), is known to affect insulin sensitivity, but the mechanism is unclear. Evidence suggests that caveolin-3 (CAV-3), a member of the caveolin family, is involved in insulin-stimulated glucose uptake. Our recent work indicated that estrogen via ER improves glucose uptake by up-regulation of CAV-3 expression. Here, we investigated the role of CAV-3 in the effect of RSV on insulin resistance in skeletal muscle both in vivo and in vitro. The results demonstrated that RSV ameliorated high-fat-diet (HFD)-induced glucose intolerance and insulin resistance in ovariectomized rats. RSV elevated insulin-stimulated glucose uptake in isolated soleus muscle in vivo and in C2C12 myotubes in vitro by enhancing GLUT4 translocation to the plasma membrane rather than increasing GLUT4 protein expression. Through ERα-mediated transcription, RSV increased CAV-3 protein expression, which contributed to GLUT4 translocation. Moreover, after knockdown of CAV-3 gene, the effects of RSV on glucose uptake and the translocation of GLUT4 to the plasma membrane, as well as the association of CAV-3 and GLUT4 in the membrane, were significantly attenuated. Our findings demonstrated that RSV via ERα elevated CAV-3 expression and then enhanced GLUT4 translocation to the plasma membrane to promote glucose uptake in skeletal muscle, exerting its protective effects against HFD-induced insulin resistance. It suggests that this pathway could represent an effective therapeutic target to fight against insulin resistance syndrome induced by HFD.
