Data were collected from 1999 to 2001 by telephone-administered surveys at preintervention and postintervention for 511 low-income, midlife adult women enrolled …

The Anti-Proliferation Effects Of Lycopene On Breast Cancer Cells, Tixieanna Dissmore

Loma Linda University Electronic Theses, Dissertations & Projects

Background: The incidence and deaths from breast cancer represent the most cause of all cancer deaths among women. Lycopene, the carotenoid in tomatoes has been associated with decreasing risk of prostate, breast, and digestive tract cancers. Various mechanisms of lycopene action have been proposed, including antioxidant activity and pro-differentiation activities. Identifying changes in the expression of proteins modified by lycopene can provide information to study the modulating effects of lycopene carcinogenesis and tumorigenesis development.

Objective: The objective was to study the anti-proliferative effects of lycopene on MCF- 7 human breast cancer cells and to identify changes in protein expression patterns. …

The Presence Of P22 Bacteriophage In Electrocautery Aerosols, Dale Stephenson, David Allcott, Michael Koch

Dale J. Stephenson

Electrosurgery units, including lasers and electrosurgical cauterizers, are commonly used for both inpatient and outpatient procedures. The generation of an aerosol plume, associated with the use of these devices, is a result of many factors including: 1) direct aspiration of blood and body fluids, 2) direct heating and vaporization of cellular fluid causing cells to explode, and 3) the carbonization of cells and cell fragments at high temperatures. Although initial studies have concluded that these plumes create only a malodorous nuisance, subsequent research suggests the presence of potential chemical and pathological hazards, including bacteria and virus. Most scientific research has …

The Influence Of Social Status On Token Women Leaders’ Expectations About Leading Male-Dominated Groups, Theodore W. Mcdonald, Loren L. Toussaint, Jennifer A. Schweiger

Public Health and Population Science Faculty Publications and Presentations

Prior research has shown that women report mostly negative expectations about being a gender-token in male-dominated work groups. We speculate that this is partially caused by the socially-ascribed status devaluation of women. In the present study we investigated the degree to which elevated social status may lessen negative expectations of gender-token women assigned to leadership positions. Sixty-three undergraduate women participated in one of three tokenism conditions: 1) nontoken, 2) gender-token, and 3) high-status gender-token. In all conditions participants were led to believe that they would be leading a group of men in a decision-making exercise. Leader expectations were then assessed. …
