Interplay of BMI and volumetric breast density measures and breast cancer risk for black and white women [PDF]

Breast Cancer Research
Background Black women have lower Breast Imaging Reporting and Data System (BI-RADS) breast density than White women, likely due to body mass index (BMI) differences.

Ionizing radiation and volumetric mammographic density

International Journal of Occupational Medicine and Environmental Health, 2022
Objectives Mammographic density (MD) refers to the percentage of dense tissue of an entire breast and was proposed to be used as a surrogate marker for breast cancer.

Evaluation of post-liquefaction volumetric strain of reconstituted samples based on soil compressibility

Soils and Foundations, 2021
In this study, we performed undrained cyclic–torsional–shear tests on clean and silty sands to examine post-liquefaction volumetric strain. Accordingly, we proposed a novel density index—ultimate volumetric strain—to evaluate the density of clean sand ...

Volumetric breast density evaluation using fully automated Volpara software, its comparison with BIRADS density types and correlation with the risk of malignancy

The Egyptian Journal of Radiology and Nuclear Medicine, 2022
Background Mammography is currently the modality of choice for mass screening of breast cancer, although its sensitivity is low in dense breasts. Besides, higher breast density has been identified as independent risk factor so it has been conceptualized ...

Volumetric mass density measurements of mesenchymal stem cells in suspension using a density meter

iScience, 2023
Summary: To use regeneratively active cells for cell therapeutic applications, the cells must be isolated from their resident tissues. Different isolation procedures subject these cells to varying degrees of mechanical strain, which can affect the yield ...

Simulating international tax designs on sugar-sweetened beverages in Mexico.

PLoS ONE, 2021
In response to the high prevalence of overweight and obesity, Mexico implemented a volumetric tax of one Mexican peso (MP) per liter of sugar-sweetened beverage (SSB) in 2014.

Cell Design Considerations and Impact on Energy Density—A Practical Approach to EV Cell Design

World Electric Vehicle Journal, 2023
Higher-energy-density, Wh L−1 or Wh kg−1, lithium-ion cells are one of the critical advancements required for the implementation of electric vehicles. This increase leads to a longer drive distance between recharges. Aside from material development, full

Area and volumetric density estimation in processed full-field digital mammograms for risk assessment of breast cancer. [PDF]

PLoS ONE, 2014
INTRODUCTION: Mammographic density, the white radiolucent part of a mammogram, is a marker of breast cancer risk and mammographic sensitivity. There are several means of measuring mammographic density, among which are area-based and volumetric-based ...

Recria de cordeiras em pastagem nativa melhorada submetida à fertilização nitrogenada: 1. Dinâmica da pastagem Rearing of lambs in improved native pasture submitted to nitrogen fertilization: 1. Pasture dynamic

Revista Brasileira de Zootecnia, 2008
Avaliou-se o efeito da fertilização com duas doses de nitrogênio (100 e 200 kg/ha, na forma de uréia) sobre as variáveis produtivas de uma pastagem nativa melhorada (3,12 ha divididos em piquetes de 0,52 ha), tendo como controle áreas sem aplicação de N.
