Electron microscope studies were done on mouse liver, from 5 min to 8 wk after an intravenous injection of liposomes containing ethylenediaminetetraacetic acid (EDTA). Livers of mice receiving an injection of liposomes containing KCL instead of EDTA or an injection of a solution of EDTA were also examined. Liposomes were shown to be phagocytized by(More)
Calorie restriction (CR) increases longevity and elicits many health promoting benefits including delaying immunosenescence and reducing the incidence of age-related diseases. Although the mechanisms underlying the health-enhancing effects of CR are not known, a likely contributing factor is alterations in immune system functioning. CR suppresses(More)
Using liposomes differing in size and lipid composition, we have studied the uptake characteristics of the liver parenchymal and Kupffer cells. Desferal labeled with iron-59 was chosen as a radiomarker for the liposomal content, because Desferal in its free form does not cross cellular membranes. At various time intervals after an intravenous injection of(More)
OBJECTIVE This study attempted to determine the relationship of physiological indices of stress (ie, cortisol and salivary immunoglobulin A) to the effort-reward imbalance model (ERI). METHODS A sample of 98 direct-care disability workers completed the Work-Related Questions II-III and provided morning saliva samples on the same day of completion, which(More)
Physiological indices of stress and ill-health (cortisol and salivary immunoglobulin A) were assessed to determine if they were predicted by Siegrist's effort-reward imbalance model (ERI) with an aim of identifying employees at risk of illness. Male Australian dairy farmers (N=66) completed the Perceived Stress Scale, Work related Questions II & III,(More)
PURPOSE We assessed how 6 psychological performance enhancement techniques (PETs) differentially improved self-efficacy (SE) and skill performance. We also assessed whether vicarious experiences and verbal persuasion as posited sources of SE (Bandura, 1982 ) were supported and, further, if the effects of the 6 PETs remained after controlling for achievement(More)
BACKGROUND Previous evaluations of the SunSmart Program have supported the link between a written sun protection policy and improved sun protection behaviours in New South Wales (NSW) primary schools. However these evaluations have relied on self-reported data and research suggests that direct observations are required to better represent schools' usual sun(More)
OBJECTIVE This study explored the role of psychosocial factors in predicting both membership to either an irritable bowel syndrome (IBS) or control group, and the severity of IBS symptoms. METHODS A total of 149 participants (82 IBS and 67 controls) completed a battery of self-report inventories assessing disposition and environment, cognitive processes,(More)
OBJECTIVE This study attempted to determine the relationship of physiological indices of stress (ie, cortisol and salivary immunoglobulin A) to the job strain and the job demand-control-support models. METHODS A sample of 98 direct-care disability workers completed the Maslach Burnout Inventory and the Job Content Questionnaire. In addition, participants'(More)
