A qualitative study of women's network social support and facility delivery in rural Ghana
(2018-11-06)Similar to many sub-Saharan African countries, maternal mortality in Ghana ranks among the highest (39th) globally. Prior research has demonstrated the impact of social network characteristics on health facility delivery ... -
Quality of life and BMI changes in youth participating in an integrated pediatric obesity treatment program
(2013-07-10)Changes in Quality of Life (QOL) measures over time with treatment of obesity have not previously been described for youth. We describe the changes from baseline through two follow up visits in youth QOL (assessed by the ... -
Quantifying the effectiveness of shoreline armoring removal on coastal biota of Puget Sound
(2018-02-23)Shoreline armoring is prevalent around the world with unprecedented human population growth and urbanization along coastal habitats. Armoring structures, such as riprap and bulkheads, that are built to prevent beach erosion ... -
Quantitative acoustic differentiation of cryptic species illustrated with King and Clapper rails
(2018-10-14)Reliable species identification is vital for survey and monitoring programs. Recently, the development of digital technology for recording and analyzing vocalizations has assisted in acoustic surveying for cryptic, rare, ... -
Quantitative analysis and comparison of 3D morphology between viable and apoptotic MCF-7 breast cancer cells and characterization of nuclear fragmentation
(2017-09-08)Morphological changes in apoptotic cells provide essential markers for defining and detec- tion of apoptosis as a fundamental mechanism of cell death. Among these changes, the nuclear fragmentation and condensation have ... -
Quantitative assessment of image motion blur in diffraction images of moving biological cells
(2016-02)Motion blur (MB) presents a significant challenge for obtaining high-contrast image data from biological cells with a polarization diffraction imaging flow cytometry (p-DIFC) method. A new p-DIFC experimental system has ... -
Racial and ethnic variations in preventive dental care utilization among middle-aged and older Americans, 1999-2008
(2013-09-23)Objective: This study examined recent trends of preventive dental care utilization among Americans aged 50 and above, focusing on variations across racial and ethnic groups including Whites, Blacks, Hispanics, American ... -
Racial differences in survival among hemodialysis patients after coronary artery bypass grafting
(2013-09-06)The aim of this study was to examine racial differences in long-term survival among hemodialysis patients after coronary artery bypass grafting (CABG). To our knowledge this has not been previously addressed in the literature. ... -
Racial disparities in healthcare provider advice to quit smoking
(2018-03-13)African-American/Black smokers are less likely than White smokers to be told to quit smoking by healthcare providers. This preliminary study examined the predictors of being told to quit separately by race for the first ... -
Raman Characterizations of Red Blood Cells With β-Thalassemia Using Laser Tweezers Raman Spectroscopy
(2018-09-06)This study aimed to study the differences in Raman spectra of red blood cells (RBCs) among patients with β-thalassemia and controls using laser tweezers Raman spectroscopy (LTRS) system.A total of 33 patients with β-thalassemia ... -
Range expansion of a fouling species indirectly impacts local species interactions
(2017-10-19)We investigated how recent changes in the distribution and abundance of a fouling organism affected the strength of interactions between a commercially important foundation species and a common predator. Increases in the ... -
A rapid assessment of co-benefits and trade-offs among Sustainable Development Goals
(2017-06-15)Achieving the United Nations’ 17 Sustainable Development Goals (SDGs) results in many ecological, social, and economic consequences that are inter-related. Understanding relationships between sustainability goals ... -
Rapid development of Purkinje cell excitability, functional cerebellar circuit, and afferent sensory input to cerebellum in zebrafish
(2014-12-19)The zebrafish has significant advantages for studying the morphological development of the brain. However, little is known about the functional development of the zebrafish brain. We used patch clamp electrophysiology in ... -
Rapid Evolution of Manifold CRISPR Systems for Plant Genome Editing
(2016-11-14)Advanced CRISPR-Cas9 based technologies first validated in mammalian cell systems are quickly being adapted for use in plants. These new technologies increase CRISPR-Cas9’s utility and effectiveness by diversifying ... -
Ras/Raf/MEK/ERK and PI3K/PTEN/Akt/mTOR cascade inhibitors: How mutations can result in therapy resistance and how to overcome resistance
(2012-10-20)The Ras/Raf/MEK/ERK and PI3K/PTEN/Akt/mTOR cascades are often activated by genetic alterations in upstream signaling molecules such as receptor tyrosine kinases (RTK). Targeting these pathways is often complex and can ... -
Ras/Raf/MEK/ERK and PI3K/PTEN/Akt/mTOR inhibitors: Rationale and importance to inhibiting these pathways in human health
(2011-03-11)The Ras/Raf/MEK/ERK and PI3K/PTEN/Akt/mTOR cascades are often activated by genetic alterations in upstream signaling molecules such as receptor tyrosine kinases (RTK). Integral components of these pathways, Ras, B-Raf, ... -
Re-analyses of “Algal” Genes Suggest a Complex Evolutionary History of Oomycetes
(2017-09-06)The spread of photosynthesis is one of the most important but constantly debated topics in eukaryotic evolution. Various hypotheses have been proposed to explain the plastid distribution in extant eukaryotes. Notably, the ... -
Re-examining the premise of isobaric collisions and a novel method to measure the chiral magnetic effect
(2019-01-22)In these proceedings we show that the premise of the isobaric and collisions to search for the chiral magnetic effect (CME) may not hold as originally anticipated due to large uncertainties in the isobaric nuclear ... -
