Abstract
In 1998, the Food and Drug Administration (FDA) approved the licensure of tobramycin solution for inhalation (TOBI). Although a number of additional antibiotics, including other aminoglycosides, beta-lactams, antibiotics in the polymyxin class, and vancomycin, have been administered as aerosols for many years, none are approved by the FDA for administration by inhalation. TOBI was approved by the FDA for the maintenance therapy of patients 6 years or older with cystic fibrosis (CF) who have between 25% and 75% of predicted forced expiratory volume in 1 second (FEV(1)), are colonized with Pseudomonas aeruginosa, and are able to comply with the prescribed medical regimen. TOBI was not approved for the therapy of acute pulmonary exacerbations in patients with CF nor was it approved for use in patients without CF. Currently, no other antibiotics are approved for administration by inhalation to patients with or without CF. The purpose of this statement is to briefly summarize the data that supported approval for licensure of TOBI and to provide recommendations for its safe use. The pharmacokinetics of inhaled aminoglycosides and problems associated with aerosolized antibiotic treatment, including environmental contamination, selection of resistant microbes, and airway exposure to excipients in intravenous formulations, will be discussed.

Abstract
According to a recent Australian Institute of Criminology report (1999) the health industry is the most violent industry in Australia. In this paper the authors aim to highlight violence as an important professional issue for Australian nurses that is currently concealed as 'part of the job'. National and international studies bring attention to the severity of the problem for nurses with a particular focus on emergency nurses. Some of the issues identified and discussed include increased waiting times and frustration; increasing use of weapons; inadequate systems of security; culture of silence; inadequate support for emergent mental health needs; lack of reporting; lack of institutional concern and systems of support, and; demands of triage nursing. The nature of workplace violence in emergency departments in New South Wales and South Australia will be explored based on the authors' research. A research pathway to explore national impact and implications of violence for nurses and nursing practice in general will be outlined.

Abstract
Alzheimer's disease (AD) is a genetically complex and heterogeneous disorder. To date, a large number of candidate genes have been associated with the disease, however none of these findings has been consistently replicated in independent datasets. In this study we report the results of family-based analyses for polymorphisms of five such candidates on chromosomes 2 (interleukin-1beta, IL-1B), 3 (butyrylcholinesterase, BCHE), 11 (cathepsin D, CTSD; Fe65, APBB1) and 12 (lipoprotein receptor-related protein-1, LRP1) that were all suggested to be associated with AD in recent case-control studies. To minimize the possibility of spurious findings due to population admixture, we used a family-based design applying the sibship disequilibrium test (SDT) as well as two-point parametric linkage analyses on families from the National Institute of Mental Health (NIMH) Genetics Initiative. Contrary to the initial reports, none of the polymorphisms that were analyzed showed evidence for association or linkage with AD in our families. Our results suggest that the previously reported associations from case-control studies are either (a) false positive results, e.g. due to type I error or population admixture, (b) smaller than initially proposed, or (c) due to linkage disequilibrium with an as yet unidentified polymorphism nearby.

Abstract
An Arabidopsis thaliana line that is mutant for the R2R3 MYB gene, AtMYB4, shows enhanced levels of sinapate esters in its leaves. The mutant line is more tolerant of UV-B irradiation than wild type. The increase in sinapate ester accumulation in the mutant is associated with an enhanced expression of the gene encoding cinnamate 4-hydroxylase, which appears to be the principal target of AtMYB4 and an effective rate limiting step in the synthesis of sinapate ester sunscreens. AtMYB4 expression is downregulated by exposure to UV-B light, indicating that derepression is an important mechanism for acclimation to UV-B in A.thaliana. The response of target genes to AtMYB4 repression is dose dependent, a feature that operates under physiological conditions to reinforce the silencing effect of AtMYB4 at high activity. AtMYB4 works as a repressor of target gene expression and includes a repression domain. It belongs to a novel group of plant R2R3 MYB proteins involved in transcriptional silencing. The balance between MYB activators and repressors on common target promoters may provide extra flexibility in transcriptional control.

Abstract
This study explored the relationships of serum insulin-like growth factors, IGF-I and IGF-II, and their binding proteins (IGFBP)-2 and IGFBP-3, with key clinicopathological parameters in 92 patients with colorectal cancer (cases). Comparisons were made with 57 individuals who had a normal colonoscopy (controls). Serial changes were examined in 27 cases. As IGF-related peptides are age- and sex-dependent, absolute concentrations were converted to standard deviation scores (SDS). Mean IGF-II SDS were elevated in Dukes A (n = 12, P< 0.001) and Dukes B (n = 25, P< 0.001) cases compared with controls, but not in advanced disease. Compared with controls, mean IGFBP-2 SDS were significantly elevated in patients with Dukes B (P< 0.001), Dukes C (n = 13, P< 0.001) and advanced disease (n = 42, P< 0.0001), with a significant trend from early to advanced disease (one-way ANOVA, P< 0.001). Furthermore, IGFBP-2 SDS were positively related to tumour size (P = 0.01) and fell significantly in patients following curative resection (P = 0.04), suggesting that circulating levels reflect tumour load. We tested the potential tumour marker characteristics of IGFBP-2 SDS against three endpoints: metastasis alone; local pelvic recurrence alone; and metastasis and recurrence combined. The sensitivities for IGFBP-2 alone (>/= + 2SD) were modest at 55%, 46%, and 52%, but in combination with CEA, increased substantially to 90%, 77% and 86%, respectively. We conclude that the serum IGF-II and IGFBP-2 profiles may provide insights into underlying biological mechanisms, and that serum IGFBP-2 may have an adjunct role in cancer surveillance in patients with colorectal cancer.

Abstract
Leptin is a metabolic regulator of the hypothalamic- pituitary-gonadal axis, and plays an important role in human reproduction. Its neuro-endocrine effects are mediated by interactions with receptors in the hypothalamus, where emotional drive is also controlled. We postulated that circulating leptin concentrations are increased in premenstrual syndrome (PMS), and that this may be associated with the psychological symptoms of the disease. We obtained fasting venous samples from 32 women with PMS and 28 women with asymptomatic menstrual cycles, matched for age, body mass index and menstrual cycle length. Leptin concentrations were measured by radioimmunoassay. Leptin concentrations increased significantly during the luteal phases of the menstrual cycles of the control and PMS groups as compared with the follicular phase, having excluded the 11 women with PMS and six controls found to be anovulatory on the basis of mid-luteal plasma progesterone concentrations from the analysis. A greater increase was observed in women with PMS than the controls (P: = 0.00006 and 0.003 respectively). Although leptin concentrations in the follicular and luteal phases were higher in PMS than the controls, the difference was only statistically significant between the follicular phases (P: = 0.001). There was no clear relationship between leptin and oestradiol or progesterone in this study. These findings suggest that leptin may play a role in the pathophysiology of the disease, and requires further evaluation.

Abstract
Twenty-five women with a previous total abdominal hysterectomy with bilateral salpingo-oophorectomy (TAH BSO) were given estradiol 50 mg implants at baseline, followed at 16 weeks with the combination of estradiol 50 mg and testosterone 100 mg. Blood samples were taken at 8-weekly intervals over 32 weeks. Serum levels of estradiol, testosterone, sex hormone binding globulin (SHBG) and agents involved in skeletal growth (growth hormone (GH), insulin-like growth factor 1 (IGF-1), carboxy terminal pro-peptide of type 1 pro-collagen (PICP; a bone formation marker) and cross-linked carboxy terminal telopeptide (ICTP; a marker of bone resorption)) were measured. Serum PICP levels increased significantly after estradiol alone (p = 0.0032) but the addition of testosterone had no significant effects on bone markers GH and IGF-1. These biochemical changes confirm previous studies, which found that the addition of testosterone did not augment the effect of estradiol implants on bone mineral density. Although physiological hormone replacement therapy in oophorectomized women would include replacement of both estradiol and testosterone, this may not to be necessary for prevention of osteoporosis where adequate serum estradiol levels are reached.

Abstract
Minor burns are commonly treated in hospital emergency departments. This study aimed to identify the nursing management of minor burns in hospitals in the Queensland region of Australia. A total of 200 questionnaires were distributed to hospitals with emergency departments in this region. The semi-structured questionnaire enquired about the respondents' initial and ongoing management of minor burns. Fifty completed questionnaires were returned, a response rate of 25%. Most respondents (80%) were registered nurses and the rest enrolled nurses. The respondents' practice was compared with that recommended in the literature. Their practice reflected the variations found in the literature, suggesting that some may not be as effective or efficient as others. The authors conclude that further research is required on the efficacy of products used in minor burn management.

Abstract
Apoptosis is a crucial biological process, and activation of caspase endoproteases is essential for proper regulation and execution of apoptosis. Because caspases also appear to be central players in several pathological states, there is a practical need within the biopharmaceutical research community for facile, noninvasive cellular assays for the discovery of compounds that modulate caspase activity. Tandem molecules of green fluorescent protein (GFP) stably expressed within cells can serve as a genetically encoded sensor of protease activity. Using this technology, we have developed a stable cellular system for the screening of agents that modulate activation of the caspase cascade. This assay technology allows for the real-time monitoring of apoptosis in situ, using conventional fluorescent plate reader detection. By applying this assay system to an actual compound screen, small-molecule inducers of cell apoptosis were reliably identified. Follow-up pharmacology confirmed that the rank-order potency of primary hits using the intracellular GFP assay corresponded to that found using a conventional, cell lysis-based assay method.
