Chinese Female Immigrants English-Speaking Ability and Breast and Cervical Cancer Early Detection Practices in the New York Metropolitan Area

Chen, Wei-Ti,Wang, Justin Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.2

Background: Breast and cervical cancers are significant causes of mortality and morbidity for Asian women, and poor English-speaking ability is a barrier to cancer prevention practices. Materials and Methods: This project tested relationships among English-speaking ability and early detection practices regarding to breast and cervical cancer among female Chinese immigrants. A descriptive cross-sectional survey was used. Results: 175 female Chinese immigrants completed the survey in the breast cancer prevention section, and 35 of them also completed the cervical cancer prevention section. Some 63% of them had heard about the clinical breast exam (CBE), but only 54% had had a CBE. While 46% of the participants were aware of their need for a Pap smear, only 31% had heard about it and had undergone a pelvic exam. Conclusions: English-speaking ability was strongly associated with immigrant women's knowledge of female cancer early detection. Culturally and linguistic issues should be considered as the first step to access immigrant population in designing future education intervention.

Purpose: Numerous studies have evaluated the association between XRCC1 Arg399Gln gene polymorphism and hepatocellular carcinoma risk in the Chinese Han population. However, the results have been inconsistent. We therefore here examined whether the XRCC1 Arg399Gln gene polymorphism confers hepatocellular carcinoma risk by conducting a meta-analysis. Methods: PubMed, Google scholar and China National Knowledge Infrastructure databases were searched for eligible articles in English and Chinese that were published before April 2012. Results: 6 studies involving 1,246 patients with hepatocellular carcinoma and 1,953 controls were included. The association between XRCC1 Arg399Gln gene polymorphism and hepatocellular carcinoma in the Chinese Han population was significant under GG vs AA (OR = 1.48, 95% CI = 1.13 to 1.94). Limiting the analysis to the studies with controls in the Hardy-Weinberg equilibrium, the results were persistent and robust. Conclusions: In the Chinese Han population, the XRCC1 Arg399Gln gene polymorphism is associated with an increased hepatocellular carcinoma risk.

Objective: Chicken essence and branched chain amino acid (BCAA) supplementation has been recognized to significantly relieve fatigue. To obtain chicken essence with high amounts of BCAA, spent hens herein was used to prepare dripped chicken essence (SCE) and compared with commercial dripped chicken essence (CCE) for in vivo anti-fatigue effect. Methods: To determine the effect on anti-fatigue by dripped chicken essence, the exhaustive swimming was performed. Thirty-two 7-week ICR mice were divided into four groups, which included the control group (CG), CCE, SCE-1X and SCE-2X. The mice were given daily oral administration (0.012 mL/g body weight/d). The fatigue index analysis was conducted weekly. Results: The results showed that SCE had a higher BCAA level as expected, and mice treated with dripped chicken essence (CCE and SCE) could significantly improve exercise performance. The lower blood lactate level, blood urea nitrogen level and creatine phosphokinase activity were found in the supplement of SCE group compared with the CCE group, which suggested that the SCE possessed strong anti-fatigue ability. This could possibly be due to the higher content of BCAA. Conclusion: In this study, SCE promoted recovery from physical fatigue in mice and elevated endurance ability. Among them, the double dose (SCE-2X) showed the strongest antifatigue ability. Taken together, spent chickens could be a good source of chicken essence to improve the effect of anti-fatigue.

Identification of crystal variants in shape-memory alloys using molecular dynamics simulations

Wu, Jo-Fan,Yang, Chia-Wei,Tsou, Nien-Ti,Chen, Chuin-Shan 테크노프레스 2016 Multiscale and multiphysics mechanics Vol.1 No.3

Shape-memory alloys (SMA) have interesting behaviors and important mechanical properties due to the solid-solid phase transformation. These phenomena are dominated by the evolution of microstructures. In recent years, the microstructures in SMAs have been studied extensively and modeled using molecular dynamics (MD) simulations. However, it remains difficult to identify the crystal variants in the simulation results, which consist of large numbers of atoms. In the present work, a method is developed to identify the austenite phase and the monoclinic martensite crystal variants in MD results. The transformation matrix of each lattice is calculated to determine the corresponding crystal variant. Evolution of the volume fraction of the crystal variants and the microstructure in Ni-Ti SMAs under thermal and mechanical boundary conditions are examined. The method is validated by comparing MD-simulated interface normals with theoretical solutions. In addition, the results show that, in certain cases, the interatomic potential used in the current study leads to inconsistent monoclinic lattices compared with crystallographic theory. Thus, a specific modification is applied and the applicability of the potential is discussed.

<P><B>Abstract</B></P> <P>In the present work, the tensile properties of 15–5 PH steel fabricated by selective laser melting (SLM) were examined with respect to the transient austenite phase. Compared with the 8%-transient-phase sample, the 18%-transient-phase one shows higher ultimate tensile strength and relatively low yield strength, as well as hardening behavior. We conducted <I>in-situ</I> neutron-diffraction study to examine the microstructure evolution for mechanistic understanding. After applying the external load, most non-equilibrium, retained austenite in the 8%-transient-phase sample transforms before the yield strength, whereas in the 18%-transient-phase sample only 50% of the austenite transforms. Accompanying with the phase transformation, a decrease in the dislocation density and the dislocation strain energy-assisted phase transformation of the ferrite phase are found in the 8%-transient-phase sample even before yielding, which, however, is not the case in the 18%-transient-phase sample. The study demonstrates the SLM enables tuning the amount of transient-phase ratio and coherency between phases to realize a mechanical property control for additive manufactured steel.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The tensile behavior was examined for 8%- and 18%-transient-phase additive manufacturing steels using in-situ neutron diffraction. </LI> <LI> The 18%-transient-phase sample exhibited higher ultimate tensile strength and low yield strength. </LI> <LI> The 18%-transient-phase specimen with more non-equilibrium γ-phase revealed a more profound strain hardening effect. </LI> </UL> </P>
