Overexpression of a tobacco glutathione S-transferase with glutathione peroxidase activity (GST/GPX) in transgenic tobacco (Nicotiana tabacum L.) enhanced seedling growth under a variety of stressful conditions. In addition to increased GST and GPX activity, transgenic GST/GPX-expressing (GST+) seedlings had elevated levels of monodehydroascorbate reductase(More)
The effect of cytokines, lipopolysaccharide, and ethanol on inducible nitric-oxide synthase (iNOS) expression was studied in C6 glial cells. Maximal induced activity, measured by the accumulation of nitrite in culture medium, occurred following treatment with lipopolysaccharide and interferon-gamma. Each cytokine alone was ineffective, whereas an optimal(More)
Gaseous emboli may be introduced into the bypass circuit both from the surgical field and during perfusionist interventions. While circuits provide good protection against massive air embolism, they do not remove gaseous microemboli (GME) from the bypass circuit. The purpose of this preliminary study is to assess the incidence of GME during bypass surgery(More)
The central nervous system is particularly susceptible to alcohol effects and toxicity. Glial cells constitute the most common cell type in the brain and play critical roles in normal brain function and during infection and injury. Astrocytes in particular seem to be important targets for alcohol neurotoxicity during both development and in adulthood. To(More)
As healthcare organizations deal with changes in the external environment, uncertainty in the internal environment is created. The purpose of this study was to explore the relationships among environmental uncertainty, social climate, and burnout among staff nurses. Multiple regression analysis was used to explore relationships among study variables.(More)
By combining traditional services and resources, the HealthQuest mobile van travels through six counties in northeast Indiana to reach those who have no easy access to health care. Existing programs that focus on meeting the needs of infants, children and adults living in rural communities via the use of mobile primary care vans are reviewed as well as this(More)
OBJECTIVE Previous studies have suggested that no single wheelchair pressure-relieving cushion material was optimal for all persons with spinal cord injury (SCI). The purpose of this study was to compare the effectiveness of the short-term pressure-relieving ability of the three most commonly prescribed wheelchair cushions (Roho, Jay, Pindot) for a person(More)
OBJECTIVE To determine whether a spontaneous luteinizing hormone (LH) surge influences the pregnancy and miscarriage rate in women with unexplained infertility undergoing controlled ovarian hyperstimulation (COH) without in vitro fertilization. DESIGN Retrospective cohort study. SETTING Ovulation Induction Clinic, Royal Hospital for Women, Sydney,(More)
The purpose of this study was to determine if there were differences in pressure relieving abilities among six commonly prescribed wheelchair cushions and whether differences were related to the participant's body mass. In addition, the participant's perception of cushion comfort was investigated. A convenience sample of 40 adult wheelchair users were(More)
Studies indicate that women experience less traditional symptoms than men and delay longer in seeking care for acute coronary syndromes. Women ignore symptoms and delay treatment due to lack of awareness of risk, passivity, inaccurate symptom attribution, and barriers to self-care. The purpose of this article is to describe the current knowledge of symptoms(More)
