Abstract
BACKGROUND AND PURPOSE We present the results of a systematic review and meta-analysis examining outcomes of endovascular coiling of wide-neck and wide-neck bifurcation aneurysms with and without stent assistance. The aim of our study was to assess angiographic and clinical outcomes. MATERIALS AND METHODS We performed a comprehensive literature search for all articles on the endovascular coiling of wide-neck and wide-neck bifurcation aneurysms. Studies meeting our inclusion criteria and abstracted data were selected by 2 independent reviewers. Primary outcomes were >6-month complete or near-complete angiographic occlusion, aneurysm recanalization, and aneurysm retreatment. Secondary outcomes included initial complete or near-complete occlusion, long-term good neurologic outcome, procedure-related morbidity, and procedure-related mortality. Data were analyzed by using random-effects meta-analysis. RESULTS In total, 38 studies including 2446 patients with 2556 aneurysms were included. For all wide-neck aneurysms, immediate complete or near-complete occlusion rate was 57.4% (95% CI, 48.1%-66.8%). Follow-up near-complete occlusion rate was 74.5% (95% CI, 68.0%-81.0%). Recanalization and retreatment rates were 9.4% (95% CI, 7.1%-11.7%) and 5.8% (95% CI, 4.1%-7.5%), respectively. Long-term good neurologic outcome was 91.4% (95% CI, 88.5%-94.2%). For wide-neck bifurcation aneurysms, initial complete or near-complete occlusion rate was 60.0% (95% CI, 42.7%-77.3%), long-term complete or near-complete occlusion rate was 71.9% (95% CI, 52.6%-91.1%), and the recanalization and retreatment rates were 9.8% (95% CI, 7.1%-12.5%) and 5.2% (95% CI, 1.9%-8.4%), respectively. CONCLUSIONS Our study of angiographic and clinical outcomes for patients with wide-neck aneurysms demonstrates that endovascular coiling with or without stent-assisted coiling is safe, with low rates of perioperative morbidity and mortality. Initial and long-term angiographic outcomes were generally satisfactory, but not ideal. These data provide some baseline comparisons against which emergent technologies can be assessed.

Abstract
OBJECTIVE MicroRNAs (miRNAs) act as key regulators of diverse cellular activities by regulating the expression of protein-coding genes. Osteoblast differentiation, a fundamental step in skeletal development, involves the activation of several signaling pathways, including transforming growth factor β (TGF-β), bone morphogenetic protein (BMP), and Wnt signaling pathways. MATERIALS AND METHODS miRNA expression was measured using TaqManRT-PCR. Western blot was used to detect the protein expression of Smad1. Luciferase reporter assay was used to measure the luciferase activity. RESULTS In this study, we found that miR-100 was expressed in mesenchymal progenitor cell lines; furthermore, its expression was reduced during osteoblast differentiation. Retroviral overexpression of miR-100 decreased Smad1 protein levels, whereas miR-100 inhibition had the opposite effect, suggesting that miR-100 acts as an endogenous attenuator of Smad1 in osteoblast differentiation. CONCLUSIONS Together, our data demonstrate that miR-100 acts as an important endogenous negative regulator of BMP-induced osteoblast differentiation.

Abstract
The REL gene, encoding the NF-κB subunit c-Rel, is frequently amplified in B-cell lymphoma and functions as a tumour-promoting transcription factor. Here we report the surprising result that c-rel-/- mice display significantly earlier lymphomagenesis in the c-Myc driven, Eμ-Myc model of B-cell lymphoma. c-Rel loss also led to earlier onset of disease in a separate TCL1-Tg-driven lymphoma model. Tumour reimplantation experiments indicated that this is an effect intrinsic to the Eμ-Myc lymphoma cells but, counterintuitively, c-rel-/- Eμ-Myc lymphoma cells were more sensitive to apoptotic stimuli. To learn more about why loss of c-Rel led to earlier onset of disease, microarray gene expression analysis was performed on B cells from 4-week-old, wild-type and c-rel-/- Eμ-Myc mice. Extensive changes in gene expression were not seen at this age, but among those transcripts significantly downregulated by the loss of c-Rel was the B-cell tumour suppressor BTB and CNC homology 2 (Bach2). Quantitative PCR and western blot analysis confirmed loss of Bach2 in c-Rel mutant Eμ-Myc tumours at both 4 weeks and the terminal stages of disease. Moreover, Bach2 expression was also downregulated in c-rel-/- TCL1-Tg mice and RelA Thr505Ala mutant Eμ-Myc mice. Analysis of wild-type Eμ-Myc mice demonstrated that the population expressing low levels of Bach2 exhibited the earlier onset of lymphoma seen in c-rel-/- mice. Confirming the relevance of these findings to human disease, analysis of chromatin immunoprecipitation sequencing data revealed that Bach2 is a c-Rel and NF-κB target gene in transformed human B cells, whereas treatment of Burkitt's lymphoma cells with inhibitors of the NF-κB/IκB kinase pathway or deletion of c-Rel or RelA resulted in loss of Bach2 expression. These data reveal a surprising tumour suppressor role for c-Rel in lymphoma development explained by regulation of Bach2 expression, underlining the context-dependent complexity of NF-κB signalling in cancer.

Abstract
OBJECTIVES To explore the differences in the features and impact on quality of life (QOL) of non-motor symptoms (NMS) of tremor dominant (TD) and postural instability gait disorder (PIGD) phenotypes early Parkinson's disease (PD), as well as the determinants of poor QOL for TD and PIGD phenotypes. METHODS This cross-sectional study recruited 301 patients with early PD and 101 healthy controls. Specific assessments used for NMS included NMS scale (NMSS), the Hamilton Rating Scale for Depression (HRSD-24), the Hamilton Anxiety Scale (HAMA), the Mini-Mental state examination (MMSE), and Addenbrooke's Cognitive Exam-Revised (ACE-R). QOL was evaluated with the PD Quality of Life Questionnaire (PDQ-39). RESULTS Tremor dominant phenotype patients were 117 (38.9%), and PIGD were 155 (51.5%). Compared with TD patients, patients with PIGD had higher frequency of NMS (9.0 ± 5.3 vs 6.7 ± 4.6, P < 0.001), NMSS total scores (39.6 ± 34.5 vs 24.4 ± 22.7, P < 0.001) and more poorly for PDQ-39 summary index (19.2 ± 14.0 vs 13.8 ± 11.5, P = 0.001). There was no difference in the impact of NMS measured with NMSS on QOL between PIGD and TD phenotypes. PIGD phenotype had little impact on poor QOL once the effect of depression was taken into account. Depression was a primary negative predictor for QOL in both TD and PIGD patients (Beta: 0.697 and 0.619, respectively, P < 0.001). CONCLUSIONS PIGD phenotype had a higher prevalence of NMS and worse QOL than TD phenotype. Depression is related to a dramatic decline in QOL in both TD and PIGD phenotype patients with PD.

Abstract
The recent combination of ultra-intense lasers and laser-accelerated electron beams is enabling the development of a new generation of compact x-ray light sources, the coherence of which depends directly on electron beam emittance. Although the emittance of accelerated electron beams can be low, it can grow due to the effects of space charge during free-space propagation. Direct experimental measurement of this important property is complicated by micron-scale beam sizes, and the presence of intense fields at the location where space charge acts. Reported here is a novel, non-destructive, single-shot method that overcame this problem. It employed an intense laser probe pulse, and spectroscopic imaging of the inverse-Compton scattered x-rays, allowing measurement of an ultra-low value for the normalized transverse emittance, 0.15 (±0.06) π mm mrad, as well as study of its subsequent growth upon exiting the accelerator. The technique and results are critical for designing multi-stage laser-wakefield accelerators, and generating high-brightness, spatially coherent x-rays.

Abstract
OBJECTIVE MicroRNA-874 (miR-874) has previously been identified as a tumor suppressor in several cancers. However, its role in colorectal cancer (CRC) has not been studied. In the present study, we aimed to investigate its potential roles in regulating cell growth and apoptosis in human CRC cells. PATIENTS AND METHODS MiR-874 expression was detected by real-time PCR analysis. Cell viability was detected by CCK-8 assay. Protein expression level was detected by Western blot, and luciferase activity assay was used to validate the interaction between mir-874 and STAT3 mRNA 3'UTR. RESULTS We found that miR-874 was significantly downregulated in CRC tissues. Gain and loss of function of miR-874 proved that miR-874 could inhibit cell growth and induce apoptosis in CRC cells. Luciferase reporter assay and Western blot analysis showed that miR-874 repressed STAT3 expression by targeting its mRNA 3'UTR. Silencing STAT3 recapitulated the phenotype of miR-874 overexpression. Moreover, the inverse correlation between miR-874 expression and STAT3 expression was validated in CRC specimens. CONCLUSIONS These data demonstrate that miR-874 functions as a tumor suppressor by repression of STAT3, suggesting its potential therapeutic value in CRC treatment.

Abstract
OBJECTIVE We studied the mechanisms of protective effects of propofol on ketamine-induced damage to neonatal cognitive function. MATERIALS AND METHODS We utilized a rat model of ketamine anaesthesia. Eighty neonatal rats (7 days after birth) were divided into four groups: normal saline group, ketamine group, and low- and high-dose propofol combined with ketamine groups. Six hours after anaesthesia, we obtained hippocampal tissue, and quantified apoptotic index and total protein concentration, and assessed global proteomics changes induced by two tested drugs. The latter changes were documented by two-dimensional electrophoresis and matrix-assisted laser desorption/ ionization time of flight mass spectrometry. To evaluate cognitive functions, water maze test was applied after animals grew for 21 days. We further repeated proteomics studies at 21 days post-anaesthesia. RESULTS Ketamine markedly up-regulated apoptotic index and decreased total protein concentration. Propofol dose-dependently reverted these adverse changes. Six hours post-anaesthesia, combined propofol and ketamine administration up-regulated the following proteins in the hippocampus: PD1A3, NDUFB10, HSPA8, ATP5JD, and PSMA1. Furthermore, the following proteins were down-regulated: PPIA, PKM2, GFAP, NSE, PPIA, PKM2, and GFAP. After 21 days, animals treated with ketamine showed marked disturbances in cognitive function as demonstrated by increased time of the water maze test, whereas propofol diminished these changes. In addition, expression of proteins largely normalized in propofol-treated animals, with only two up-regulated proteins (FUBP3 and PRDX5) and three down-regulated proteins (GAPDH, AKR1A1, and VCP). CONCLUSIONS Adverse effects of ketamine on cognitive function are reverted by propofol, also through beneficial effects on protein expression in the hippocampus.

Abstract
BACKGROUND AND PURPOSE Endovascular coiling is an alternative to surgical clipping for ruptured intracranial aneurysms. However, no large multicenter prospective study has compared coiling and clipping in patients with poor-grade ruptured aneurysms. We aimed to determine differences in postoperative complications and clinical outcome between the 2 treatments in this group of patients. MATERIALS AND METHODS A Multicenter Poor-Grade Aneurysm Study was a prospective, multicenter, observational registry of consecutive patients who presented with poor-grade ruptured aneurysms. Three hundred sixty-six patients were enrolled from October 2010 to March 2012. "Poor-grade aneurysm" was defined as a World Federation of Neurosurgical Societies grade of IV or V at the time of aneurysm treatment. Two hundred sixty-two patients received aneurysm treatment within 21 days and were included. Clinical outcomes were assessed at discharge and at 6 and 12 months by the modified Rankin Scale. RESULTS One hundred thirty-three (50.8%) patients underwent endovascular coiling. Unadjusted analysis showed that the outcome rate (mRS 0-1 or mRS 0-2) at 6 and 12 months in patients undergoing coiling was higher than that in patients undergoing clipping. In adjusted analyses, there was no statistically significant difference in outcomes at 6 and 12 months between the 2 groups. The risk of radiologic hydrocephalus was higher in patients treated with coiling than that in those treated with clipping (adjusted OR, 3.36; 95% CI, 1.13-10.01; P = .030). CONCLUSIONS The long-term outcome in selected patients was similar between endovascular coiling and clipping for poor-grade ruptured aneurysms. The risk of radiologic hydrocephalus was higher after endovascular treatment of poor-grade aneurysms.

Abstract
The objective of the present study was to investigate the role of γ-aminobutyric acid type A receptor (GABA(A)R) in lipopolysaccharide (LPS)-induced acute lung injury (ALI) in rats. Thirty-two male wistar rats were randomly divided into four groups. Rats in the GABA group were pretreated with LPS and GABA, while those in the bicuculline (BIC) group were pretreated with LPS and bicuculline. We assessed the arterial blood gas, dry/wet ratio, and the level of tumor necrosis factor-α (TNF-α), IL-6, malondialdehyde, and superoxide dismutase 6 h after the immunization. Paraffin sections of samples were detected using the steptavidin-peroxidase method. Protein expression was detected using sodium dodecyl sulfate-polyacrylamide gel electrophoresis and western blotting. PaO2 in the LPS group was significantly lower than that in the control rats. Activation of GABA-mediated signaling by GABA increased the expression of GABA(A)R in airway bronchial and alveolar epithelial cells. Blockade of the GABA(A)R by bicuculline limited the expression of this receptor. The GABA group rats had higher levels of tissue TNF-α and IL-6 than in ALI rats and control rats. The BIC group rats demonstrated an opposite expression level compared to the GABA group rats. Our results suggest that the GABA(A)R could aggravate the inflammatory response syndrome and oxidative stress in the lungs and play an essential role in LPS-induced acute lung injury. It provides a novel method to study the incidence and mortality of ALI during the peroperative period.

Abstract
We report the first measurement of the target single-spin asymmetry, A(y), in quasielastic scattering from the inclusive reaction (3)He(↑)(e,e') on a (3)He gas target polarized normal to the lepton scattering plane. Assuming time-reversal invariance, this asymmetry is strictly zero for one-photon exchange. A nonzero A(y) can arise from the interference between the one- and two-photon exchange processes which is sensitive to the details of the substructure of the nucleon. An experiment recently completed at Jefferson Lab yielded asymmetries with high statistical precision at Q(2)=0.13, 0.46, and 0.97 GeV(2). These measurements demonstrate, for the first time, that the (3)He asymmetry is clearly nonzero and negative at the 4σ-9σ level. Using measured proton-to-(3)He cross-section ratios and the effective polarization approximation, neutron asymmetries of -(1-3)% were obtained. The neutron asymmetry at high Q(2) is related to moments of the generalized parton distributions (GPDs). Our measured neutron asymmetry at Q(2)=0.97 GeV(2) agrees well with a prediction based on two-photon exchange using a GPD model and thus provides a new, independent constraint on these distributions.

Abstract
It is well known that estrogen exerts neuroprotective effect against various neuronal damages. However, the estrogen receptor (ER) that mediates estrogen neuroprotection has not been well established. In this study, we investigated the potential receptor that mediates estrogen neuroprotection and the underlying molecular mechanisms. Hydrogen peroxide (H2O2) was chosen as an agent in our study to mimic free radicals that are often involved in the pathogenesis of many degenerative diseases. We found that in human SY5Y and IMR-32 cells, the estrogen neuroprotection against H2O2 toxicity was abrogated by knockdown of a variant of estrogen receptor-α, ER-α36. We also studied the rapid estrogen signaling mediated by ER-α36 in neuroprotective effect and found the PI3K/AKT and MAPK/ERK1/2 signaling mediated by ER-α36 is involved in estrogen neuroprotection. We also found that GPER, an orphan G protein-coupled receptor, is not involved in ER-α36-mediated rapid estrogen response. Our study thus demonstrates that ER-α36-mediated rapid estrogen signaling is involved in the neuroprotection activity of estrogen against oxidative toxicity.

Abstract
BACKGROUND The burning of moxa floss in moxibustion releases moxa smoke containing a substantial amount of particulate matter (PM10) into the environment, which has generated safety concerns about its potential health impact. DESIGN Plasmid scission assay was performed using PM10 collected from moxibustion clinics. METHODS PM10 was collected in winter 2012 by burning three types of moxa floss samples in moxibustion simulation clinics, and the resulting PM10 mass concentration was calculated. Oxidative capacity of the PM10 samples was measured by plasmid scission assay and the percentage of DNA damage at dosage 500 µg ml(-1) (D500) was calculated by linear regression analysis. RESULTS The average PM10 mass concentration of samples A (3 years and 3:1 ratio), B (3 years and 8:1 ratio) and C (10 years and 3:1 ratio) was 273.33, 172.22 and 168.89 μg/m(3), respectively. The D500 oxidative capacity of PM10 was on average 24.25%, 27.83% and 28.07% for samples A, B and C, respectively. No significant difference was found in the PM10-induced oxidative damage by moxa smoke produced from the three types of moxa floss. CONCLUSIONS PM10 mass concentrations from the three types of moxa floss combustion exceeded internationally recommended levels. Despite so, PM10 mass concentration of moxa smoke was much lower than biomass and coal combustion and similar to that of gas combustion. The oxidative DNA damage induced by individual PM10 in moxibustion environment was lower than that reported in other environments, indicating that moxibustion-derived PM10 might not be as injurious to human health as generally assumed.

Abstract
Blockade of extracellular high mobility group box 1 (HMGB1) can significantly prolong murine cardiac allograft survival. Here, we determined the role of HMGB1 in xenotransplantation. Sprague-Dawley rat hearts were transplanted heterotopically into BALB/c mice. Xenografts without any treatment developed predominant acute vascular rejection within 6 days. Both passively released HMGB1 from xenografts and actively secreted HMGB1 from infiltrated immune cells were significantly increased after xenotransplantation. HMGB1-neutralizing antibody treatment significantly prolonged xenograft survival and attenuated pathologic damage, immune cell infiltration, and HMGB1 expression and release in the xenografts. Compared to control IgG treatment evaluated at study endpoint, treatment with HMGB1-neutralizing antibody markedly suppressed xenoreactive B cell responses, as evidenced by the significant inhibition of anti-rat antibody production and deposition in xenografts at Day 6 posttransplant. Furthermore, treatment with anti-HMGB1 antibody suppressed B cell activation and reduced IFN-γ and IL-17A production after xenotransplantation. These results demonstrate for the first time that HMGB1 plays an important role in mediating acute xenograft rejection. Thus, we have shown that neutralization of extracellular HMGB1 can significantly inhibit xenoreactive B cell responses and delay xenograft rejection in a rat-to-mouse model of xenotransplantation, uncovering new insights in the role of HMGB1 in transplantation.

Abstract
Biomaterial-implants are frequently used to restore function and form of human anatomy. However, the presence of implanted biomaterials dramatically elevates infection risk. Paradoxically, dental-implants placed in a bacteria-laden milieu experience moderate failure-rates, due to infection (0.0-1.1%), similar to the ones of joint-arthroplasties placed in a near-sterile environment (0.1-1.3%). Transcutaneous bone-fixation pins breach the immune-barrier of the epidermis, exposing underlying sterile-tissue to an unsterile external environment. In contrast to dental-implants, also placed in a highly unsterile environment, these pins give rise to relatively high infection-associated failure-rates of up to 23.0%. Herein, we attempt to identify causes as to why dental-implants so often succeed, where others fail. The major part of all implants considered are metal-made, with similar surface-finishes. Material choice was therefore discarded as underlying the paradox. Antimicrobial activity of saliva has also been suggested as a cause for the success of dental-implants, but was discarded because saliva is the implant-site-fluid from which viable bacteria adhere. Crevicular fluid was discarded as it is largely analogous to serum. Instead, we attribute the relative success of dental-implants to (1) ability of oral tissues to heal rapidly in the continuous presence of commensal bacteria and opportunistic pathogens, and (2) tolerance of the oral immune-system. Inability of local tissue to adhere, spread and grow in presence of bacteria and an intolerant immune-system are identified as the likely main causes explaining the susceptibility of other implants to infection-associated failure. In conclusion, it is the authors' belief that new anti-infection strategies for a wide range of biomaterial-implants may be derived from the relative success of dental-implants.

Abstract
Studies have shown that Annexin A2 (ANXA2) is related with tumor proliferation, apoptosis, differentiation, invasion, migration, and drug resistance. The purpose of this study was to investigate the role and its mechanisms of ANXA2 in multi-drug-resistance (MDR) in gastric cancer. ANXA2 expression in both gastric cancer tissues and cell lines were detected by quantitative real-time PCR (RT-qPCR) and Western blotting. The cell proliferation was measured by SRB assay. The pool of siRNA against ANXA2 was designed and synthesized and then transfected into resistant gastric cancer SGC7901/DDP cells. ANXA2 expression was detected by RT-qPCR and Western blotting. Drug sensitivities of SGC7901/DDP cells to P-gp-related drug (doxorubicin) and P-gp-non-related drugs (5-FU and cisplatin) were measured by SRB assay. Expression of MDR-related genes and phosphorylation of AKT and MAPKs were also detected by RT-qPCR and Western blotting. Results showed that ANXA2 expression was significantly higher in gastric specimens than that in normal tissues, and negatively correlated with the differentiation level of gastric cancer. In addition, ANXA2 expression level was higher in SGC7901/DDP cells than that in parent SGC7901 cells. After knock-down ANXA2 expression using ANXA2 small interfering RNA, the drug sensitivity of SGC7901/DDP cells to doxorubicin, 5-FU and DDP increased. Delivery of ANXA2 siRNA significantly downregulated the expression of P-gp, MRP1 and Bcl-2, while markedly upregulated Bax in SGC7901/DDP cells. However, several other MDR factors such as GST-π, TOPO-I and TOPO-II had no obvious changes. Additionally, phosphorylation of P38MAPK and AKT, but not ERK1/2 or JNKs was specifically decreased in SGC7901/DDP cells after ANXA2 siRNA delivery. Importantly, P38MAPK and AKT inhibitor increased the drug sensitivity of SGC701/DDP cells in a similar way as ANXA2 siRNAs does. ANXA2 is involved in gastric cancer MDR through regulating p38MAPK and AKT pathways as well as certain MDR factors.

Abstract
A new quadrivalent influenza vaccine has been available for influenza B, which can pose a significant global health burden. Shanghai has the highest GDP and largest metropolitan population in China. To understand the impact of influenza B in Shanghai in terms of age-related incidence and relative prevalence compared with other subtypes, we conducted this retrospective epidemiological study of influenza B in the 2009-2014 seasons. A total of 71 354 outpatients with influenza-like illness were included, and both lineages of influenza B and subtypes of influenza A were identified using real-time RT-PCR. The antigenic characteristics of influenza B isolates were analysed by sequencing and reciprocal haemagglutinin inhibition assay. On average, 33.45% of influenza strains were influenza B, and 40.20% of strains isolated from children were influenza B. The incidence of influenza B was highest (12.52 per 100 people with influenza-like illness) in children ages 6-17 years and usually peaked in this age group at the early stage of an influenza B epidemic. Overall, both matched and mismatched influenza B strains co-circulated in Shanghai annually, and 44.57% of the circulating influenza B belonged to the opposite lineage of the vaccine strains. We concluded that influenza B has caused a substantial impact in Shanghai and that school-aged children play a key role in the transmission of influenza B. Hence, it may be beneficial to prioritize influenza vaccination for school-aged children to mitigate the outbreaks of influenza B.

Abstract
We report experimental results on the production and characterization of asymmetric and composite supersonic gas flows, created by merging independently controllable flows from multiple nozzles. We demonstrate that the spatial profiles are adjustable over a large range of parameters, including gas density, density gradient, and atomic composition. The profiles were precisely characterized using three-dimensional tomography. The creation and measurement of complex gas flows is relevant to numerous applications, ranging from laser-produced plasmas to rocket thrusters.

Abstract
BACKGROUND AND PURPOSE Infarct volume may predict clinical outcome in acute stroke, but manual segmentation techniques limit its routine use. We hypothesized that computer-assisted volumetric analysis to quantify acute infarct volume will show no difference compared with manual segmentation but will show increased speed of performance and will correlate with outcome. MATERIALS AND METHODS Patients with acute stroke younger than 18 years were included. Infarct volume on diffusion-weighted imaging was quantified by using computer-assisted volumetric and manual techniques. The Pediatric Stroke Outcome Measure scored clinical outcome. Computer-assisted volumetric and manual techniques were compared with correlation coefficients. Linear regression analysis compared Pediatric Stroke Outcome Measure with core infarct volume and percentage volume of brain infarction. RESULTS Twenty-three patients were analyzed (mean age, 4.6 years). Mean infarct volume from computer-assisted volumetric and manual approaches was 65.6 and 63.7 mL, respectively (P = .56). Concordance correlation between methods was 0.980, and between users, 0.968. The mean times for segmentation between computer-assisted volumetric and manual techniques were <1 minute and 7.3 minutes (P < .001). The mean infarct volumes for good and poor outcome groups were 7.4 and 75.7 mL (P < .007). The mean percentages of infarcted brain parenchyma for good and poor outcome groups were 0.6% and 10.4% (P < .006). Volumes of 32 mL and 3% for infarcted brain were associated with poor outcome in all patients. CONCLUSIONS Computer-assisted volumetric quantification of infarct volume is reproducible, is significantly faster than manual techniques, and may have important applications for future clinical workflow. Core infarct volumes and infarct percentage correlated with outcome severity.

Abstract
AIMS Endothelium-derived protein disulphide isomerase (PDI) is required for thrombus formation in vivo. But, how to control PDI overproduction in oxidized low-density lipoprotein (oxLDL)-activated vascular endothelial cells (VECs) is not well understood. In this study, we try to answer this question using our newly identified activator of mTOC1 3-benzyl-5-((2-nitrophenoxy) methyl)-dihydrofuran-2 (3H)-one (3BDO) that has been shown to protect VECs. METHODS First, we performed a proteomics analysis on the oxLDL-activated vascular VECs in the presence or absence of 3BDO. Next, we constructed the heterogeneous nuclear ribonucleoprotein E1 (hnRNP E1) mutants at Ser43 and used the RNA-ChIP technique to investigate the relationship between hnRNP E1 and PDI production. Furthermore, we examined the effect of 3BDO on oxLDL-altered phosphorylation of Akt1 and Akt2. Finally, we studied the effect of 3BDO on oxLDL-altered PDI protein level in apolipoprotein E(-/-) mice with advanced atherosclerosis. RESULTS In VECs, oxLDL-increased PDI protein level, induced hnRNP E1 phosphorylation at Ser43, suppressed the binding of hnRNP E1 to PDI 5'UTR and induced the phosphorylation of Akt2 but not Akt1. All of these processes were blocked by 3BDO. Importantly, Ser43 mutant of hnRNP E1 inhibited the increase of PDI protein level and the decrease of the binding of hnRNP E1 and PDI 5'UTR induced by oxLDL. Furthermore, 3BDO suppressed oxLDL-induced PDI protein increase in the serum and plaque endothelium of apolipoprotein E(-/-) mice. CONCLUSION hnRNP E1 is a new regulator of PDI translation in oxLDL-activated VECs, and 3BDO is a powerful agent for controlling PDI overproduction.
