BACKGROUND We have compared mutation analysis by DNA sequencing and Amplification Refractory Mutation System™ (ARMS™) for their ability to detect mutations in clinical biopsy specimens. METHODS We have evaluated five real-time ARMS assays: BRAF 1799T>A, [this includes V600E and V600K] and NRAS 182A>G [Q61R] and 181C>A [Q61K] in melanoma, EGFR 2573T>G(More)
The cherry leaf roller (Caloptilia serotinella) produces three distinct types of substrate-borne signals—scraping, plucking, and vibrating—during interactions between conspecifics. Signals were recorded using a piezoelectric sensor, and behavioral experiments tested the hypothesis that signaling functions in territorial disputes over costly leaf shelters.(More)
OBJECTIVE To assess the effectiveness of antibiotic treatment of women with symptoms of urinary tract infection but negative urine dipstick testing. DESIGN Prospective, double blind, randomised, placebo controlled trial. SETTING Primary care, among a randomly selected group of general practitioners in Christchurch, New Zealand. PARTICIPANTS 59 women(More)
BACKGROUND Prevalence estimates of chronic disease vary according to the technique used. Questionnaire surveys may be susceptible to inaccuracies, which may be overcome by addition of a checklist of conditions. This paper presents SF-36 scores and NHS consultation rates for people reporting individual chronic diseases or disabilities in two questionnaire(More)
BACKGROUND Event-based measures suggest that emotional adversity in childhood has a long-term health impact, but less attention has been paid to chronic emotional stressors such as family conflict, harsh discipline or lack of affection. This study aimed to assess the impact of the latter on health problems and illness in adulthood. METHODS Logistic(More)
AIM To examine the incidence of thick melanoma in New Zealand from 1994-2004 and investigate associations with melanoma thickness. METHOD The New Zealand Health Information Service provided information on all registrations for malignant melanoma from 1994-2004. Age-standardised registration rates were calculated. Logistic regression analysis was(More)
OBJECTIVES To compare the efficacy, safety, and acceptability of treatment with intravenous antibiotics for cellulitis at home and in hospital. DESIGN Prospective randomised controlled trial. SETTING Christchurch, New Zealand. PARTICIPANTS 200 patients presenting or referred to the only emergency department in Christchurch who were thought to require(More)
There are several groups of researchers developing cell-based biosensors for chemical and biological warfare agents based on electrophysiologic monitoring of cells. In order to transition such sensors from the laboratory to the field, a general-purpose hardware and software platform is required. This paper describes the design, implementation, and(More)
BRAF mutation testing from circulating free DNA (cfDNA) using the amplification refractory mutation testing system (ARMS) holds potential as a surrogate for tumor mutation testing. Robust assay validation is needed to establish the optimal clinical matrix for measurement and cfDNA-specific mutation calling criteria. Plasma- and serum-derived cfDNA samples(More)
BACKGROUND during the third stage of labour there are two approaches for care provision - active management or physiological (expectant) care. The aim of this research was to describe, analyse and compare the midwifery care pathway and outcomes provided to a selected cohort of New Zealand women during the third stage of labour between the years 2004 and(More)
