Abstract
Abstract
In our study, liquid tin (Sn) was mixed with molten polyethylene using an internal mixer; the interfacial tension between the liquid Sn and molten polyethylene was measured using the deformed drop retraction method. The results showed that liquid Sn separated when the Sn content was higher than approximately 2 % by volume because of the interfacial tension of up to 167 mN/m and the 106-fold viscosity difference between the liquid Sn and the molten polyethylene. When Sn separation did not occur, the effects of the mixing time and rotary speed on the degree of mixing and the Sn particle size were analyzed using thermogravimetric analysis and scanning electron microscopy. The results showed that the effects of mixing time and rotary speed on the degree of mixing and Sn particle size can be combined as the impact of specific energy input. With increasing specific energy input, the degree of mixing initially increased and subsequently remained constant, while the Sn particle size initially decreased and subsequently remained constant. The refinement of the dispersed phase was completed with a low specific energy input, but the homogenization of the dispersed phase required a higher specific energy input to achieve completion, revealing the relationship between distributive mixing and dispersive mixing.

Abstract
The calibration factors of alpha-track radon detectors (ATDs) are essential for accurate determination of indoor radon concentrations. In this paper, the effects of atmospheric parameters on the calibration factors were theoretically studied and partially testified. Based on the atmospheric thermodynamics theory and detection characteristics of the allyl diglycol carbonate (CR-39), the calibration factors for 5 types of ATDs were calculated through Monte Carlo simulations under different atmospheric conditions. Simulation results showed that the calibration factor increased by up to 31% for the ATDs with a decrease of air pressure by 35.5 kPa (equivalent to an altitude increase of 3500 m), and it also increased by up to 12% with a temperature increase from 5 °C to 35 °C, but it was hardly affected by the relative humidity unless the water-vapor condensation occurs inside the detectors. Furthermore, it was also found that the effects on calibration factors also depended on the dimensions of ATDs. It indicated that variations of the calibration factor with air pressure and temperature should be considered for an accurate radon measurement with a large dimensional ATD, and water-vapor condensation inside the detector should be avoided in field measurements.

Abstract
OBJECTIVES To investigate the effect of multimodality treatment of advanced paediatric hepatoblastoma and the factors affecting the prognosis. PATIENTS AND METHODS 35 childhood patients were treated with multimodality treatments consisting of chemotherapy, surgery, interventional therapy, and autologous peripheral blood stem cell transplantation. Patients were followed up every month. RESULTS 33 patients completed the follow-up, of which 17 were in complete remission, 5 were in partial remission, 1 case got worse, and 10 died. The remission rate was 66.7% (22/33), and the overall survival rate was 69.7% (23/33). 1 patient with advanced hepatoblastoma got high-dose chemotherapy combined with autologous peripheral blood stem cell transplantation (APBSCT) treatment, and a primary lesion by 18 x 15 x 9 cm reduced to 10 x 8 x 4 cm. Remote metastases significantly alleviated, and partial remission reached six months. The overall survival was 9 months after transplantation. Patients with the mixed phenotype of hepatoblastoma had a worse prognosis than with the epithelial phenotype (p < 0.001), and patients in stage IV had a lower survival rate than in stage III (p < 0.001). CONCLUSIONS Multimodality treatment can effectively improve remission rate and prolong the survival of children with the advanced hepatoblastoma. In addition, alpha-fetoprotein (AFP), hepatoblastoma pathological classification and staging are of great use in prediction of prognosis.

Abstract
BACKGROUND Limited physiological data for Tibetan macaques are available at present. This study will provide more rationale for evaluating this species. METHODS Thirty-seven Tibetan macaques (15 males and 22 females) were used in this study. Somatometric measurements, clinical chemistry and hematology parameters, insulin, and C-peptide were analyzed. RESULTS Females had higher values of waist and waist hip ratio (WHR) than males in somatometric measurements. There were no significant differences between the two genders in hematology. Significant differences between males and females were only found for aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in biochemistry testing. In addition, females had higher fasting insulin and C-peptide than males. There was a strongly positive correlation between age and some somatometric parameters. CONCLUSIONS These physiological data will provide veterinarians and researchers with baseline values to evaluate experimental results using Tibetan macaques.

Abstract
Widely used release criteria for patients receiving radiopharmaceuticals (NUREG-1556, Vol. 9, Rev.1, Appendix U) are known to be overly conservative. The authors measured external exposure rates near patients treated with I, Tc, and F and compared the measurements to calculated values using point and line source models. The external exposure dose rates for 231, 11, and 52 patients scanned or treated with I, Tc, and F, respectively, were measured at 0.3 m and 1.0 m shortly after radiopharmaceutical administration. Calculated values were always higher than measured values and suggested the application of "self-shielding factors," as suggested by Siegel et al. in 2002. The self-shielding factors of point and line source models for I at 1 m were 0.60 ± 0.16 and 0.73 ± 0.20, respectively. For Tc patients, the self-shielding factors for point and line source models were 0.44 ± 0.19 and 0.55 ± 0.23, and the values were 0.50 ± 0.09 and 0.60 ± 0.12, respectively, for F (all FDG) patients. Treating patients as unshielded point sources of radiation is clearly inappropriate. In reality, they are volume sources, but treatment of their exposures using a line source model with appropriate self-shielding factors produces a more realistic, but still conservative, approach for managing patient release.

Abstract
PURPOSE To find potential serum biomakers that can predict clinical outcome upon treatment in non-small cell lung cancer (NSCLC) by analyzing differential proteins in serum with different sensitivity of chemoradiotherapy (CRT). MATERIALS AND METHODS Sera were collected from 37 NSCLC patients before they were treated with concurrent cisplatin-based CRT. According to the outcome of CRT, the patients were divided into sensitive group and resistant one. The proteins in sera were separated by two-dimensional gel electrophoresis after the high abundance proteins were removed from sera. The significantly differentially expressed proteins between two groups were analyzed by liquid chromatography and tendem mass spectrometry (LC-MS/MS). Then, an additional 50 serum samples were used for ELISA analysis to validate the identified proteins that we got in the experiment. RESULTS Proteins in sera of each group were successfully separated on 2D gels. There were significant discrepancies in serum protein expression between NSCLC patients with different CRT sensitivity. Among eight differently expressed proteins, six proteins were successfully identified with five of which higher expressed and one lower expressed in resistant group. The increased Alpha-1-antitrypsin (α1-AT) level in resistant group comparing to sensitive one were validated by ELISA analysis (p<0.05). CONCLUSIONS Proteomic approach may serve as a useful method in detecting the potential biomarkers for predicting the outcome of treatment in NSCLC patients. NSCLC patients with high α1-AT level in serum before CRT may have a worse treatment outcome.

Abstract
To construct a fusion cytokine protein with more and stronger bioactivities to enhance the immunity of the cytokine alone, we expressed interleukin (IL)-6/(IL)-2 from giant panda (Ailuropoda melanoleuca) in Escherichia coli as a 59.4-kDa fusion protein. Subsequently, the inclusion bodies were solubilized with 8 M urea and applied onto a Ni-nitrilotriacetic acid column. The final production of IL-6/IL-2 reached 6 mg/L in soluble form, and the purified final product was >96% pure. In Western blot assays, the recombinant IL-6/IL-2 was recognized by polyclonal antibodies against IL-6 and IL-2 of giant panda. The results demonstrated that the protein mixture contained correctly folded IL-2 and IL-6 proteins. A 3-(4,5-dimethylthiazol-2-yl) 2,5-diphenyltetrazolium bromide assay demonstrated that IL-6/IL-2 can promote lymphocyte proliferation and differentiation. These data suggest that the fusion protein could be used to develop a novel immunoadjuvant to enhance the immunity of animals against infectious diseases.

Abstract
Objective: To investigate whether preincisional parecoxib administration can reduce postoperative pain and modulate the inflammatory cytokine response to a greater extent than preincisional parecoxib administration in total hip replacement patients. Methods: Patients were randomized to receive 40 mg parecoxib intravenously either before or after skin incision (preincisional and postincisional groups, respectively). Morphine was administered for postoperative analgesia. Visual analogue pain scale (VAS) scores and morphine consumption were recorded at 1, 6, 18 and 24 h postoperation. Plasma levels of interleukin (IL)-6, IL-8 and tumour necrosis factor-a were measured 30 min before skin incision and 6 h postoperation. Results: Compared with the post - incisional group, VAS pain scores at 1 and 6 h postoperation were significantly lower in the preincisional group. Morphine consumption was significantly lower in the preincisional group at 6, 18 and 24 h postoperation. In both groups, IL-6 and IL- 8 levels increased significantly at 6 h postoperation compared with pre - operation, and the preincisional group had significantly lower levels of IL-6 and IL-8 at 6 h postoperation compared with the postincisional group. Conclusions: Preincisional parecoxib administration reduced postoperative pain and morphine consumption compared with post - incisional administration, and attenuated IL-6 and IL-8 production 24 h after hip replacement surgery.

Abstract
BACKGROUND AND AIMS Nearly 25% of normal weight individuals display abnormal metabolic profiles associated with obesity. As a wide range in body fat percentage (%BF) exists for BMI-defined normal weight individuals, we investigated whether elevated %BF (determined using DXA) was associated with cardiometabolic dysregulation among 977 normal weight subjects (192 men, 785 women) from the Canadian province of Newfoundland and Labrador. METHODS AND RESULTS BMI and %BF were measured after a 12-h fasting period. Cardiometabolic abnormalities considered included elevated triglyceride, glucose and hsCRP levels, decreased HDL cholesterol, insulin resistance, and hypertension. Subjects were classified as metabolically healthy (0 or 1 cardiometabolic abnormality) or abnormal (≥2 cardiometabolic abnormalities) and divided into sex-specific %BF tertiles as follows: low (≤15.2% men, ≤29.7% women), medium (15.3-20.7%% men, 29.8-34.9%% women) and high (≥20.8% men, ≥35.0% women). The prevalence of the metabolically abnormal phenotype was higher among medium and high %BF subjects (12.0% and 19.5%, respectively) compared to the low group (7.4%; p < 0.05). Furthermore, the odds of being metabolically abnormal were 1.61 (95% CI 0.94-2.77) for medium %BF subjects compared to the low group and nearly tripled for high %BF subjects (OR 2.73, 95% CI 1.63-4.86). ORs remained significant after further adjustment for waist circumference. CONCLUSION Our findings indicate that those with elevated %BF are at increased risk of developing cardiometabolic disease despite having a normal BMI. Future development of adequate screening tools to identify these individuals is crucial to the prevention of obesity-associated disease.

Abstract
Recent observations indicate prostatic diseases are comorbidities of systemic metabolic dysfunction. These discoveries revealed fundamental questions regarding the nature of prostate metabolism. We previously showed that prostate-specific ablation of PPARγ in mice resulted in tumorigenesis and active autophagy. Here, we demonstrate control of overlapping and distinct aspects of prostate epithelial metabolism by ectopic expression of individual PPARγ isoforms in PPARγ knockout prostate epithelial cells. Expression and activation of either PPARγ 1 or 2 reduced de novo lipogenesis and oxidative stress and mediated a switch from glucose to fatty acid oxidation through regulation of genes including Pdk4, Fabp4, Lpl, Acot1 and Cd36. Differential effects of PPARγ isoforms included decreased basal cell differentiation, Scd1 expression and triglyceride fatty acid desaturation and increased tumorigenicity by PPARγ1. In contrast, PPARγ2 expression significantly increased basal cell differentiation, Scd1 expression and AR expression and responsiveness. Finally, in confirmation of in vitro data, a PPARγ agonist versus high-fat diet (HFD) regimen in vivo confirmed that PPARγ agonization increased prostatic differentiation markers, whereas HFD downregulated PPARγ-regulated genes and decreased prostate differentiation. These data provide a rationale for pursuing a fundamental metabolic understanding of changes to glucose and fatty acid metabolism in benign and malignant prostatic diseases associated with systemic metabolic stress.

Abstract
STAR's measurements of directed flow (v1) around midrapidity for π±, K±, KS0, p, and p[over ¯] in Au+Au collisions at √[sNN]=200 GeV are presented. A negative v1(y) slope is observed for most of produced particles (π±, K±, KS0, and p[over ¯]). In 5%-30% central collisions, a sizable difference is present between the v1(y) slope of protons and antiprotons, with the former being consistent with zero within errors. The v1 excitation function is presented. Comparisons to model calculations (RQMD, UrQMD, AMPT, QGSM with parton recombination, and a hydrodynamics model with a tilted source) are made. For those models which have calculations of v1 for both pions and protons, none of them can describe v1(y) for pions and protons simultaneously. The hydrodynamics model with a tilted source as currently implemented cannot explain the centrality dependence of the difference between the v1(y) slopes of protons and antiprotons.

Abstract
We have demonstrated higher-order optical resonance node detection by using an integrated disk microresonator from through port of the coupling bus waveguide. In addition to the fundamental mode, the disk resonator has higher-order whispering gallery modes. The excited second-order higher-order mode has a node at the position where the electromagnetic energy of the fundamental mode is close to a maximum. This high resolution measurement of optical resonance mode profile has a variety of applications for optical sensing and detection. The self-referencing characteristics of the two optical resonance modes have potential to achieve optical detection independent of external perturbation, such as temperature change.
