Stress And Strain Adaptation In Load-Dependent Remodeling Of The Embryonic Left Ventricle, Christine Buffinton Dec 2012

Stress And Strain Adaptation In Load-Dependent Remodeling Of The Embryonic Left Ventricle, Christine Buffinton

Faculty Journal Articles

Altered pressure in the developing left ventricle (LV) results in altered morphology and tissue material properties. Mechanical stress and strain may play a role in the regulating process. This study showed that confocal microscopy, three-dimensional reconstruction, and finite element analysis can provide a detailed model of stress and strain in the trabeculated embryonic heart. The method was used to test the hypothesis that end-diastolic strains are normalized after altered loading of the LV during the stages of trabecular compaction and chamber formation. Stage-29 chick LVs subjected to pressure overload and underload at stage 21 were reconstructed with full trabecular morphology …

Human Calmodulin Methyltransferase: Expression, Activity On Calmodulin, And Hsp90 Dependence, Sophia Magen, Roberta Magnani, Sitvanit Haziza, Eli Hershkovitz, Robert Houtz, Franca Cambi, Ruti Parvari

Horticulture Faculty Publications

Deletion of the first exon of calmodulin-lysine N-methyltransferase (CaM KMT, previously C2orf34) has been reported in two multigene deletion syndromes, but additional studies on the gene have not been reported. Here we show that in the cells from 2p21 deletion patients the loss of CaM KMT expression results in accumulation of hypomethylated calmodulin compared to normal controls, suggesting that CaM KMT is essential for calmodulin methylation and there are no compensatory mechanisms for CaM methylation in humans. We have further studied the expression of this gene at the transcript and protein levels. We have identified 2 additional …

The Role Of Dairy Products And Milk In Adolescent Obesity: Evidence From Hong Kong’S ‘‘Children Of 1997’’ Birth Cohort, Shi Lin Lin, Marie Tarrant, Lai Ling Hui, Man Ki Kwok, Tai Hing Lam, Gabriel M. Leung, Mary Schooling

Publications and Research

Background
Observational studies, mainly from Western populations, suggest dairy consumption is inversely associated with adiposity. However, in these populations the intake range is limited and both diet and obesity may share social patterning. Evidence from non-Western developed settings with different social patterning, is valuable in distinguishing whether observed associations are biologically mediated or socially confounded.

Objective
To examine the associations of milk or other dairy product consumption with adolescent obesity.

Methods
We used multivariable linear regression models to examine the associations of milk or other dairy product consumption, obtained from a food frequency questionnaire, at 11 years with body mass …

The Essence Of Beauty : Examining The Impact Of Idealized Beauty Standards On College-Age African America Women, Tiffany M. Paschal Dec 2012

The Essence Of Beauty : Examining The Impact Of Idealized Beauty Standards On College-Age African America Women, Tiffany M. Paschal

Theses, Dissertations, and Projects

This qualitative study examined the psychological and emotional effects of contemporary western society's standards of beauty on college-age African American women. Various studies on perception of beauty have explored body image perception from a middle class Caucasian perspective; and as a result, body image conceptualization from the perspective of African American women has gone unnoticed (Spurgas, 2005, Hatcher, 2007, Hall 1995). Previous literature suggests that African American women define self-perception and beauty differently from mainstream definitions. This study involved conducting a focus group with eighteen students between the ages of 18 and 25 who were enrolled at a Historically Black …

Evaluation Of Mixture Viscosity Models In The Prediction Of Two-Phase Flow Pressure Drops, Aung N.Z, Yuwono T Dec 2012

Evaluation Of Mixture Viscosity Models In The Prediction Of Two-Phase Flow Pressure Drops, Aung N.Z, Yuwono T

ASEAN Journal on Science and Technology for Development

Nine existing mixture viscosity models were tested for predicting a two-phase pressure drop for oil-water flow and refrigerant (R.134a) flow. The predicted data calculated by using these mixture viscosity models were compared with experimental data. Predicted data from using one group of mixture viscosity models had a good agreement with the experimental data for oil-water two-phase flow. Another group of viscosity models was preferable for gas-liquid flow, but these models gave underestimated values with an error of about 50%. A new and more reliable mixture viscosity model was proposed for use in the prediction of pressure drop in gas-liquid two-phase …
