Breast Cancer Mortality among Asian-American Women in California: Variation according to Ethnicity and Tumor Subtype

Carol Parise,Vincent Caggiano 한국유방암학회 2016 Journal of breast cancer Vol.19 No.2

Purpose: Asian-American women have equal or better breast cancer survival rates than non-Hispanic white women, but many studies use the aggregate term “Asian/Pacific Islander” (API) or consider breast cancer as a single disease. The purpose of this study was to assess the risk of mortality in seven subgroups of Asian-Americans expressing the estrogen receptor (ER), progesterone receptor (PR), or human epidermal growth factor receptor 2 (HER2) tumor marker subtypes and determine whether the risk of mortality for the aggregate API category is reflective of the risk in all Asian ethnicities. Methods: The study included data for 110,120 Asian and white women with stage 1 to 4 first primary invasive breast cancer from the California Cancer Registry. The Asian ethnicities identified were Pacific Islander, Southeast Asian (SEA), Indian Subcontinent, Chinese, Japanese, Filipino, and Korean. A Cox regression analysis was used to compute the risk of breast cancer-specific mortality in seven Asian ethnicities and the combined API category versus white women within each of the ER/PR/HER2 subtypes. Hazard ratios (HRs) and 95% confidence intervals (CIs) were computed. Results: For the ER+/PR+/ HER2− subtype, the combined API category showed a 17% (HR, 0.83; 95% CI, 0.76–0.91) lower mortality risk. This was true only for SEA (HR, 0.75; 95% CI, 0.61–0.91) and Japanese women (HR, 0.60; 95% CI, 0.45–0.81). In the ER+/PR−/HER2− subtype, SEA (HR, 0.57; 95% CI, 0.38–0.84) and Filipino women (HR, 0.71; 95% CI, 0.51–0.97) had a lower risk of mortality. Japanese (HR, 0.49; 95% CI, 0.25–0.99) and Filipino women (HR, 0.74; 95% CI, 0.58–0.94) had a lower HR for the ER−/PR−/HER2+ subtype. For triple-positive, ER+/PR+/HER2+ (HR, 0.84; 95% CI, 0.71–0.98) and triple-negative, ER−/PR−/HER2− (HR, 0.84; 95% CI, 0.74–0.94) subtypes, only the API category showed a lower risk of mortality. Conclusion: Breast cancer-specific mortality among Asian-American women varies according to their specific Asian ethnicity and breast cancer subtype.

Geological survey and numerical modeling of the potential failure mechanisms of underground caves

Piernicola Lollino,Mario Parise,Vincenzo Martimucci 한국자원공학회 2013 Geosystem engineering Vol.16 No.1

Natural or man-made underground caves potentially represent a serious hazard to the built-up areas. Urban development and construction of infrastructures is generally carried out without taking into account the possibility of interacting with subsurface cavities, and the corresponding hazard these might pose. In addition, loss of memory of man-made cavities under the historic part of many towns adds further problems. This is especially true for countries with a long history, such as Italy, where during the centuries a large number of artificial cavities have been excavated underground for different purposes. Assessment of the stability of rock masses in these settings is not an easy matter, since it requires, in addition to the geological and engineering background, speleological skills and techniques in order to explore and survey the cavities, identify the type of failures occurring therein, and collect the data necessary for the implementation of specific numerical analyses, these being aimed at defining the stress–strain state of the mass. In this article we present an approach involving cavers, geologists, and engineers to assess the rock mass stability in natural and man-made cave, aimed at determining the control of rock failures in the formation of sinkholes. The methodology is described through the application to a natural karst cave and an anthropogenic cavity in Apulia, SE Italy. In both cases, following a detailed speleological survey which was specifically addressed to define the complete cave geometry, the geomechanical characterization of the carbonate rock mass was carried out and the data so obtained used to evaluate the rock mass stability by means of numerical modeling.

Seeking the most powerful and practical real-world sorbents for gaseous benzene as a representative volatile organic compound based on performance metrics

Szulejko, Jan E.,Kim, Ki-Hyun,Parise, John Elsevier 2019 Separation and purification technology Vol.212 No.-

<P><B>Abstract</B></P> <P>To assess the best sorbents available in real-world treatment of airborne volatile organic compounds (VOCs), we explored four sorbent performance metrics (10% breakthrough volume, space velocity, regeneration cycles, and cost) against benzene, a representative VOC, using well-known sorbents in the partial pressure (P<SUB>benzene</SUB>) range 0.01 – 1 Pa. Accordingly, some common materials (e.g., activated carbons) outperformed novel materials like MOFs. The performance of MOFs was often exaggerated as data were generally collected under unrealistic P<SUB>benzene</SUB> (e.g., >5,000 Pa). The use of metrics appropriate to real-world conditions is thus critical for selecting sorbents.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Performance of sorbents in real-world treatment of VOC is important for AQM purposes. </LI> <LI> Metrics were selected as breakthrough volume, space velocity, regeneration cycles, and cost. </LI> <LI> Sorbent performance metrics were checked for benzene in the partial pressure 0.01–1 Pa. </LI> <LI> Some common materials (e.g., activated carbons) have the potential to outperform others. </LI> <LI> The use of metrics appropriate to real-world conditions is critical for selecting sorbents. </LI> </UL> </P>

Effects of copper loading on NH3-SCR and NO oxidation over Cu impregnated CHA zeolite

Nusnin Akter,Xianyin Chen,John Parise,Jorge Anibal Boscoboinik,김태진 한국화학공학회 2018 Korean Journal of Chemical Engineering Vol.35 No.1

Cu/CHA catalysts with various Cu loadings (0.5 wt%-6.0 wt%) were synthesized via incipient wetness impregnation. The catalysts were applied to the selective catalytic reduction (SCR) of NO with NH3 and NO oxidation reaction. XRD and N2 adsorption-desorption data showed that CHA structure was maintained with the incorporation of Cu, while specific surface areas decreased with increasing Cu loading. At intermediate Cu loading, 4 wt%, the highest NH3-SCR activity was observed with ~98% N2 selectivity from 150 oC to 300 oC. Small amounts of water, 2%, slightly increased NO conversion in addition to the remarkable N2O and NO2 reduction at high temperature. Water effects are attributed to the improved Cu ion reducibility and mobility. NO oxidation results provided no relation between NO2 formation and SCR activity. Physicochemical properties, NO conversion, N2 selectivity, and activation energy data showed that impregnated samples’ molecular structure and catalytic activity are comparable to the conventional ion-exchanged (IE) samples’ ones.

Calderone, P.J.,Banerjee, D.,Plonka, A.M.,Kim, S.J.,Parise, J.B. Elsevier Sequoia [etc.] 2013 Inorganica chimica acta Vol.394 No.-

A series of three magnesium trimesate coordination networks was synthesized from identical reaction mixtures by varying synthetic temperature. Mg(HBTC)(DMF)<SUB>2</SUB>.[(CH<SUB>3</SUB>)<SUB>2</SUB>NH] (1; BTC=trimesate; space group P6<SUB>3</SUB>/m, a=16.596(4)A, c=14.351(8)A) crystallizes at 65<SUP>o</SUP>C, Mg<SUB>3</SUB>(BTC)(HCOO)<SUB>3</SUB>(DMF)<SUB>3</SUB> (2; space group P@?3, a=13.928(2)A, c=8.025(6)A) crystallizes at 100<SUP>o</SUP>C, and Mg<SUB>3</SUB>(BTC)<SUB>2</SUB>(DMF)<SUB>4</SUB> (3; space group P2<SUB>1</SUB>/c, a=17.490(4)A, b=11.940(2)A, c=18.460(4)A, β=116.87(3)<SUP>o</SUP>) crystallizes at a temperature of 180<SUP>o</SUP>C. Each network contains metal-coordinated solvent DMF molecules, but thermodynamics and solvent hydrolysis play major roles in structure formation. Compounds 1 and 2 are two-dimensional networks which incorporate hydrolysis byproducts. Compound 3 is a three-dimensional network and shows no inclusion of byproducts. The series follows the trend of increased network connectivity resulting from increased temperature. Each of the networks show a weak photoluminescence response, suggesting that coordinated solvent molecules and interlayer species play a role in quenching photoluminescence.

Backpackers' Virtual Mobility

Cody Paris,Victor Teye 세계문화관광학회 2008 Conference Proceedings Vol.9 No.0

Mobility is inherently part of the backpacker phenomenon. In the past the mobility has been physical, but recent innovations in communication technology, in particular online social communities, have added a virtual component to the mobility of backpackers. This study explores the complex sociality backpackers now maintain by examining the convergence of the internet and communication technologies and physical travel before, during, and after backpackers' trips. The results of the study suggest that backpackers now maintain a complex sociality made up of face to face interactions, virtual interactions, and co-presence. Backpackers have fully adapted the new communication tools into their travel activities.
