The deleterious effects of plastic debris on the marine environment were reviewed by bringing together most of the literature published so far on the topic. A large number of marine species is known to be harmed and/or killed by plastic debris, which could jeopardize their survival, especially since many are already endangered by other forms of(More)
A review was carried out to identify the exotic mosquito species intercepted in New Zealand to 2004, together with their origins, pathways and ports of entry into the country. A total of 171 interceptions have been recorded since 1929. There was little or no taxonomic information available for many, but at least 27 exotic species not yet established in New(More)
BACKGROUND Olive plant leaves (Olea europaea L.) have been used for centuries in folk medicine to treat diabetes, but there are very limited data examining the effects of olive polyphenols on glucose homeostasis in humans. OBJECTIVE To assess the effects of supplementation with olive leaf polyphenols (51.1 mg oleuropein, 9.7 mg hydroxytyrosol per day) on(More)
Populations of the Australian redback spider, Latrodectus hasseltii Thorell 1870, were first recorded in New Zealand in the early 1980s and in Osaka, Japan in 1995. Reliable records suggest that naturalised populations of L. hasseltii in New Zealand are present only in Central Otago and New Plymouth. In Central Otago, L. hasseltii feeds on endangered(More)
We evaluated the quality and content of fish oil supplements in New Zealand. All encapsulated fish oil supplements marketed in New Zealand were eligible for inclusion. Fatty acid content was measured by gas chromatography. Peroxide values (PV) and anisidine values (AV) were measured, and total oxidation values (Totox) calculated. Only 3 of 32 fish oil(More)
To date, there has been no confirmed, indigenously acquired case of arthropod-borne viral disease in New Zealand, but this may change in the near future due to the presence of exotic vectors and regular influx of infected humans. The risk of a disease outbreak may be aggravated if other exotic mosquito vectors become established, in particular Aedes(More)
OBJECTIVE To better understand the cardiac limitations during exercise in adolescents with type 2 diabetes mellitus (T2DM), we measured left ventricular performance with magnetic resonance imaging (MRI) during exercise in diabetic and nondiabetic adolescents. RESEARCH DESIGN AND METHODS Thirteen subjects with T2DM, 27 overweight/obese nondiabetic(More)
Phenolic compounds derived from the olive plant (Olea europaea L.), particularly hydroxytyrosol and oleuropein, have many beneficial effects in vitro. Olive leaves are the richest source of olive phenolic compounds, and olive leaf extract (OLE) is now a popular nutraceutical taken either as liquid or capsules. To quantify the bioavailability and metabolism(More)
BACKGROUND We sought to determine the incidence of permanent hypopituitarism in a potentially high-risk group: young children after structural traumatic brain injury (TBI). METHODS We conducted a cross-sectional study with longitudinal follow-up. Dynamic tests of pituitary function (GH and ACTH) were performed in all subjects and potential abnormalities(More)
To now, New Zealand has been spared arboviral diseases, except for the odd imported infection. However, two exotic vector mosquitoes (Ochlerotatus camptorhynchus and Ochlerotatus notoscriptus) have become established in New Zealand and the routine arrival of infected people from overseas may soon lead to local arboviral transmission. Large populations of(More)
