Abstract

Physical activity has been inversely associated with the risk of hip fracture, however, few studies have been conducted on the contributions from different domains of physical activity. This study was performed to investigate the association between daily household activities, leisure time physical activity, work-related physical activity and total physical activity during a 24-h period, and the risk of hip fracture. In the Swedish National March Cohort we followed 23,881 men and women aged of 50 and over from 1997 until 2010. Information on domain-specific physical activity was collected at baseline using a questionnaire. We fitted separate multivariable adjusted Cox proportional hazard models to each domain to obtain hazard ratios (HRs) with 95% confidence intervals (CIs). Each model was mutually adjusted for the other domains of physical activity. During a mean follow-up period of 12.2 years we identified 824 incidents of hip fracture. Subjects who spent less than 1 h per week engaged in daily household activities had an 85% higher risk of hip fracture than subjects spending ≥6 h per week carrying out daily household activities (HR 1.85; 95% CI 1.01–3.38). Subjects engaged in leisure time physical activities for >3.1 MET-h/day had a 24% lower risk of hip fracture (HR 0.76; 95% CI 0.59–0.98) than subjects spending <1.1 MET-h/day performing such activities. No association was found between hip fracture and work-related or total physical activity. We conclude that daily household activities and leisure time physical activity may independently decrease the risk of hip fracture in those aged 50 and over.

However, their toxicity issues caused by heavy metals in QDs remain to be addressed, in particular for their in vivo biomedical applications. In this study, a parallel comparative investigation in vitro and in vivo is presented to disclose the impact of synthetic methods and their following surface modifications on the toxicity of QDs. Cellular assays after exposure to QDs were conducted including cell viability assessment, DNA breakage study in a single cellular level, intracellular reactive oxygen species (ROS) receptor measurement, and transmission electron microscopy to evaluate their toxicity in vitro. Mice experiments after QD administration, including analysis of hemobiological indices, pharmacokinetics, histological examination, and body weight, were further carried out to evaluate their systematic toxicity in vivo. Results show that QDs fabricated by the thermal decomposition approach in organic phase and encapsulated by an amphiphilic polymer (denoted as QDs-1) present the least toxicity in acute damage, compared with those of QDs surface engineered by glutathione-mediated ligand exchange (denoted as QDs-2), and the ones prepared by coprecipitation approach in aqueous phase with mercaptopropionic acid capped (denoted as QDs-3). With the extension of the investigation time of mice respectively injected with QDs, we found that the damage caused by QDs to the organs can be gradually recovered. This parallel comparative investigation suggests that synthetic methods and their resulting surface microenvironment play vital roles in the acute toxicity profiles of QDs. The present study provides updated insights into the fabrication and surface engineering of QDs for their translational applications in theranostics.Keywords: comparative investigation, amphiphilic polymer, glutathione, mercaptopropionic acid, DNA breakage, surface microenvironment

This study was designed to investigate the expression of microRNA-381 (miR-381) and its function in the radioresistance of ESCC.Methods: In this study, miR-381 expression was first detected in ESCC cell lines and tissue samples by quantitative real-time polymerase chain reaction (qRT-PCR). Then, the effects of miR-381 expression on growth, apoptosis, and radiosensitivity of ESCC cells were analyzed by MTT, colony formation, and flow cytometry, respectively. Dual-luciferase reporter assays were performed to validate the regulation of a putative target of miR-381, in corroboration with qRT-PCR and Western blotting assays.Results: ESCC cell lines or tissues were found to express significantly lower miR-381 than normal esophageal epithelial cells or adjacent normal tissues, respectively. Ectopic expression of miR-381 in ESCC cell lines blocked proliferation, reduced colony formation, enhanced apoptosis, and increased radiosensitivity by enhancing irradiation-induced apoptosis. In addition, dual-luciferase reporter assays showed that miR-381 binds to the 3'-untranslated region of X-linked inhibitor of apoptosis protein (XIAP), suggesting that XIAP should be a direct target of miR-381. Re-expression of miR-381 suppressed XIAP protein expression in ESCC cells, and the effects of miR-381 upregulation on ESCC cells were found to be similar with silencing of XIAP. In addition, XIAP mRNA expression significantly increased in ESCC tissues and was inversely correlated with miR-381 expression.Conclusion: The results of this study suggest that miR-381/XIAP pathway contributed to the growth inhibition, increase in apoptosis, and enhancement of radiosensitivity in ESCC cells Therefore, miR-381 may be a potential therapeutic target in human ESCC.

381. Investigation on intrusion of bentonite–sand mixtures in fractures with consideration of sand content and seepage effects.

Author

Xu, L. B., Ye, W. M., Liu, Z. R., Wang, Q., and Chen, Y. G.

Abstract

During the long-term operation of a repository, bentonite–sand mixture could invade into fractures in the surrounding rock with infiltration of groundwater, resulting in loss of bentonite from the barrier with possible leakage of nuclides and consequently endangers the safety of the repository. In this work, an apparatus was designed with an artificial joint (fracture) being made between two parallel stacked transparent acrylic plates with a stainless-steel gasket inserted. Intrusion tests were conducted on the mixture specimens with different sand contents into artificial fractures with two sizes. A flow with constant velocity was applied to simulate seepage in the surrounding rock formations. Images were regularly captured with a camera, and parameters including the intrusion distance and widths of the non-accessory and accessory mineral rings were determined using a commercial software. Simultaneously, fluid was collected at the outlet and the erosion rate bentonite was determined by a turbidimeter. Finally, based on the force equilibrium, an intrusion model for describing bentonite–sand mixture intrusion into fractures with consideration of sand content and seepage effects was established and verified. Results show that the intrusion distance, two-region widths, and erosion mass decrease significantly with increasing sand content. After intrusion, the dry density of the bentonite specimen nearby the extrusion port decreases with increasing sand content and fracture size. Meanwhile, results of XRD tests indicate that the ratio of accessory minerals in the accessory mineral ring was higher than that in the pure Gaomiaozi bentonite specimen. Verifications confirmed that the intrusion model proposed in this work can well simulate the data measured. [ABSTRACT FROM AUTHOR]

Abstract

The structured surface-enhanced pool boiling process and associated heat transfer enhancement characteristics are numerically investigated by using the pseudopotential multiphase flow lattice Boltzmann (LB) model coupled finite difference method (FDM). In the current study, the effects of different microstructure geometries(square structures, triangular serrated structures, triangular-raised structures) and varying spacing in triangular-raised structures (d = 0, 22, 44, 66, 88, 110 l.u. (lattice units)) on boiling heat transfer (BHT) characteristics and bubble dynamics behavior are studied in detail. The results showed that microstructure can accelerate bubble nucleation. Among the three microstructures, the heat transfer performance of triangular-raised structures was significantly better than that of square and triangular serrated structures in the nucleate boiling (Ja number is 0.124-0.145). The oscillation and deformation of bubbles led to the lateral migration of bubbles, the continuous nucleation of small bubbles. The phenomenon of re-wetting of heating surface occurred in the process of bubble migration, necking, deformation and detachment was found, which enhances heat transfer in nucleate boiling. At the same time, the growth, oscillation and detachment of bubbles also perturb the liquid and enhance the natural convection around the bubbles. Therefore the main BHT mechanism of nucleate boiling on the three kinds of structured surface is the combined action of transient heat conduction and micro-convection. The variation of the spacing between microstructures showed an important effect on the BHT performance of the heating surface and the generation of activated nucleation sites in the nucleate boiling. Triangular-raised structures can enhance transient heat conduction and micro-convection, with the strongest enhancement effect at d = 66 l.u when the Ja number is 0.124. [ABSTRACT FROM AUTHOR]

Abstract

N-(2-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-3-methyl-butanamide is an important boric acid derivative. In this article, the title compound is obtained by a two-step substitution reaction. The structure of the title compound is verified by FTIR, 1H and 13C NMR, and MS. Simultaneously, the single crystal structure of the title compound is gauged by X-ray diffraction and subjected to crystallographic and conformational analyses. Density functional theory (DFT) is applied to further calculate the molecular structure and compare it with X-ray values. The result of the conformational analysis shows that the molecular structure optimized by DFT is identical with the single crystal structure determined by single crystal X-ray diffraction. In addition, DFT is used to further study the molecular electrostatic potential and frontier molecular orbitals of the title compound, revealing the molecular structure characteristics, conformation, and some special physical and chemical properties of the title compound.

Abstract

This paper presents a bounding surface model for unsaturated compacted bentonite based on the critical state theory and bounding surface plasticity. In the proposed model, a shear bounding surface was proposed for describing shear behaviour. A new loading collapse curve was defined to describe suction effects on the yield behaviour. Meanwhile, wetting and drying bounding surfaces were proposed to represent the swelling and shrinkage volume change induced by suction changes. Furthermore, isotropic hardening rule was incorporated into the bounding surface formulation with an associated flow rule. Finally, a simplified form of plastic modulus was introduced to describe elastoplastic behaviour within the bounding surface and the Hvorslev surface was employed to describe the peak strength of heavily compacted bentonite. The proposed model has great potential to realistically describe some features of compacted bentonite including strain hardening or strain softening; monotonic loading under isotropic or one-dimensional compression; yield behaviour due to suction; swelling behaviour induced by changes of suction, etc. With the proposed model, simulations were performed on results of oedometer tests conducted under different suctions, triaxial compression tests and swelling potential tests. Validation showed that good agreements were reached between simulations and the experimental results. A loading collapse bounding surface was proposed to describe the influence of initial dry density on yield stress A shear bounding surface was proposed for describing hardening or softening behaviour The Hvorslev surface was introduced to reflect the peak strength and the water content effect on the peak strength Wetting–drying bounding surface was proposed for describing the volume change induced by suction changes [ABSTRACT FROM AUTHOR]

Abstract

Background: The incidence of congenital heart disease (CHD) is growing at a rapid speed worldwide, which due to changes of both environmental and lifestyle exposures. This study aimed to explore how the non-genetic risk factors of maternal and perinatal conditions influenced onset of CHD in infants.Methods: Infants with congenital heart disease diagnosed by echocardiography from May 2012 to December 2013 were recruited as positive cases, while healthy individuals without congenital heart disease recruited at the same period were regarded as controls. The general situation of parents and the exposure to environmental factors during perinatal period in the case group and the control group were investigated by questionnaires.Results: A total of424 questionnaires of infants with congenital heart disease and 362 healthy controls were finally collected. We analyzed the risk factors during perinatal period of their mothers showed that their mothers took drugs in early pregnancy (odds ratio [OR]=4.41, 95 % confidence interval [CI]:2.41-6.73), viral infection (OR = 2.97, 95% CI: 1.62-5.73), house decoration (OR = 1.82, 95% CI: 1.43-3.75), hair dyeing and scalding (OR = 2.24, 95% CI:1.46-4.05), parents' exposures to work environment pollution (OR = 2.77, 95% CI: 2.03-5.38) were independent risk factors for cardiovascular malformations. With the increase of exposure factors, the risk of congenital heart disease increased significantly. When pregnant women were exposed to three or more risk factors at the same time, the risk of infants with congenital heart disease in was 17.24 times higher than that of single-factor exposure.Conclusions: Together, the incidence of CHD in infants is correlated with the exposure to perinatal risk factors.

Abstract

We study the production of the exotic charged charmoniumlike state Zc±(3900) in pp¯ collisions through the sequential process ψ(4260)→Zc±(3900)π∓, Zc±(3900)→J/ψπ±. Using the subsample of candidates originating from semi-inclusive weak decays of b-flavored hadrons, we measure the invariant mass and natural width to be M=3902.6−5.0+5.2(stat)−1.4+3.3(syst) MeV and Γ=32−21+28(stat)−7+26(syst) MeV, respectively. We search for prompt production of the Zc±(3900) through the same sequential process. No significant signal is observed, and we set an upper limit of 0.70 at the 95% credibility level on the ratio of prompt production to the production via b-hadron decays. The study is based on 10.4 fb−1 of pp¯ collision data collected by the D0 experiment at the Fermilab Tevatron collider.

Using the subsample of candidates originating from semi-inclusive weak decays of b-flavored hadrons, we measure the invariant mass and natural width to be M = 3902.6(-5.0)(+5.2)(stat)(-1.4)(+3.3)(syst) MeV and Gamma = 32(-21)(+28)(stat)(-7)(+26)(syst) MeV, respectively. We search for prompt production of the Z(c)(+/-)(3900) through the same sequential process. No significant signal is observed, and we set an upper limit of 0.70 at the 95% credibility level on the ratio of prompt production to the production via b-hadron decays. The study is based on 10.4 fb(-1) of p (p) over bar collision data collected by the D0 experiment at the Fermilab Tevatron collider.

Abstract

Background: The use of biomarkers of environmental exposure to explore new risk factors for pancreatic cancer presents clinical, logistic, and methodological challenges that are also relevant in research on other complex diseases. Objectives: First, to summarize the main design features of a prospective case-control study –nested within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort– on plasma concentrations of persistent organic pollutants (POPs) and pancreatic cancer risk. And second, to assess the main methodological challenges posed by associations among characteristics and habits of study participants, fasting status, time from blood draw to cancer diagnosis, disease progression bias, basis of cancer diagnosis, and plasma concentrations of lipids and POPs. Results from etiologic analyses on POPs and pancreatic cancer risk, and other analyses, will be reported in future articles. Methods: Study subjects were 1533 participants (513 cases and 1020 controls matched by study centre, sex, age at blood collection, date and time of blood collection, and fasting status) enrolled between 1992 and 2000. Plasma concentrations of 22 POPs were measured by gas chromatography - triple quadrupole mass spectrometry (GC-MS/MS). To estimate the magnitude of the associations we calculated multivariate-adjusted odds ratios by unconditional logistic regression, and adjusted geometric means by General Linear Regression Models. Results: There were differences among countries in subjects’ characteristics (as age, gender, smoking, lipid and POP concentrations), and in study characteristics (as time from blood collection to index date, year of last follow-up, length of follow-up, basis of cancer diagnosis, and fasting status). Adjusting for centre and time of blood collection, no factors were significantly associated with fasting status. Plasma concentrations of lipids were related to age, body mass index, fasting, country, and smoking. We detected and quantified 16 of the 22 POPs in more than 90% of individuals. All 22 POPs were detected in some participants, and the smallest number of POPs detected in one person was 15 (median, 19) with few differences by country. The highest concentrations were found for p,p’-DDE, PCBs 153 and 180 (median concentration: 3371, 1023, and 810 pg/mL, respectively). We assessed the possible occurrence of disease progression bias (DPB) in eight situations defined by lipid and POP measurements, on one hand, and by four factors: interval from blood draw to index date, tumour subsite, tumour stage, and grade of differentiation, on the other. In seven of the eight situations results supported the absence of DPB. Conclusions: The coexistence of differences across study centres in some design features and participant characteristics is of relevance to other multicentre studies. Relationships among subjects’ characteristics and among such characteristics and design features may play important roles in the forthcoming analyses on the association between plasma concentrations of POPs and pancreatic cancer risk. © 2018 Elsevier Inc.
