9, 10 and 11 To the best of our knowledge this is the first such paediatric case report. In our case there was symptomatic benefit with some objective improvement in lung function but ultimately reaccumulation of some pleural fluid a year in to therapy. Admittedly, there is also no way of knowing the relative contributions made by the institution of prophylactic co-trimoxazole or a low-fat diet. Roehr et al. published a systematic review identifying 35 children in the medical literature HTS assay treated with somatostatin or octreotide for chylothorax.12 The cases identified were mainly post-operative with none associated

with Generalised Lymphatic Dysplasia. A positive treatment effect was reported in the majority. Importantly, a number of side effects were noted. Aside from minor effects such as transient hyperglycaemia and cutaneous flushing, particular care is advised in children who are vulnerable to vascular insults and cases of strangulation-ileus in a child with asplenia and necrotizing enterocolitis in a neonate with coarctation of the aorta were

cited.12 In conclusion, somatostatin analogues represent a potentially useful treatment modality in http://www.selleckchem.com/products/BIBF1120.html children with chylothorax associated with GLD and warrant consideration in cases refractory to other management. Repeated thoracocentesis of chylothoraces may lead to problems with nutrition and presents major practical issues in children who may require PIK-5 general anaeasthesia for the procedure.4 Further studies are required to establish an evidence base for the efficacy and safety of somatostatin analogues; although

the rarity of this group of conditions makes it unlikely that a formal randomised controlled trial will be feasible.12 and 13 All authors confirm that they have no relevant conflicts of interest relating to the above manuscript. We are grateful to Dr Tony de Soyza, Freeman Hospital, Newcastle upon Tyne, UK for information on the current management of the patient. “
“A 76-year old male with a three-year history of Myelodysplasia presented with symptoms and signs of right upper lobe pneumonia. Initial investigations revealed neutropenia (neutrophil count 1.0) for which he was commenced on Clarithromycin, Tazocin and Gentamicin. Blood and sputum cultures for bacteria including acid-fast bacilli and urinary antigen for Legionella were negative. A chest x-ray confirmed right upper lobar pneumonia with a bulging horizontal fissure (Fig. 1). On going high-grade pyrexia and haemoptysis prompted a change of antibiotic regime to include antifungal agents after repeat sputum cultures grew Stenotrophomonas maltophilia and Candida melibiosica. A contrast enhanced CT chest was performed to investigate the cause of haemoptysis. This demonstrated right upper lobe pneumonia as well as a large pulmonary artery pseudoaneurysm ( Fig. 2).

, 2012). In a review on this topic, however, conflicting results were found, with most studies indicating that mineral nutrition is not affected by glyphosate tolerance trait or application of glyphosate (Duke et al.,

2012). Glyphosate has been shown to reduce photosynthesis and nutrient uptake in GM-soy, in greenhouse and field trials, both for first and second generation of glyphosate resistant soy plants. High glyphosate application rates have been shown to reduce alfa-linolenic acid (ALA, 18:3n−3) but increase oleic acid (OL, 18:1n−9) ( Bellaloui, Zablotowicz, Reddy, & Abel, 2008), i.e., producing a less healthy profile of fatty acids. Glyphosate may also, depending on soil type, alter micronutrient status, in PLX3397 order particular Mn and Zn. Our data showed significantly Pembrolizumab higher Zn concentrations in organic soy samples (mean 37.0 mg/kg), but no differences between GM and conventional soy samples (mean 30.4 and 31.7 mg/kg, respectively). This indicates that factors other than glyphosate may be relevant, such as the use of

organic versus synthetic fertiliser or long-term accumulated differences in soil treatment and quality. Status of the micronutrient Mn was not affected by the production system in our samples. In general, a healthy microbial community, ‘the plant microbiome’, in the soil of the rhizosphere is an important contributing factor for plant trait characteristics and plant health (Lundberg et al., 2012). Glyphosate has the potential to adversely affect microbial communities present in soils into which plants are rooted, i.e. increased colonisation by Fusarium ( Kremer & Means, 2009). AMPA is mildly phytotoxic, and leads to

reduced photosynthesis (‘yellowing’) and transpiration rates in soy plants (Ding, Reddy, Zablotowicz, Bellaloui, & Bruns, 2011). Other ingredients of glyphosate-based herbicides have also been described as detrimental to GM-soy. We found a significant positive correlation between AMPA residue levels in the GM soybeans and increasing levels of LA and iron (Fe). The acceptance level of glyphosate in food and feed, i.e., the maximum residue level (MRL) GNAT2 has been increased by authorities in countries where Roundup-Ready GM crops are produced or where such commodities are imported. In Brazil, the MRL in soybean in 2004 was increased from 0.2 to 10 mg/kg: a 50-fold increase, but only for GM-soy. The MRL for glyphosate in soybeans has also increased in the US and Europe. In Europe, it was raised from 0.1 to 20 mg/kg in 1999, and the same MRL of 20 mg/kg was adopted by the US based on recommendations of the Codex Alimentarius Commission. In all of these cases, MRL values appear to have been adjusted, not based on new evidence indicating glyphosate toxicity was less than previously understood, but pragmatically in response to actual observed increases in the content of residues in glyphosate-tolerant GM soybeans.

The same behaviour was observed for epicatechin In agreement wit

The same behaviour was observed for epicatechin. In agreement with other studies (Prieur et al., 1994), gallocatechin and epigallocatechin were present at lower levels. The percentage of gallocatechin ranged from 6% to 23% of the total monomers. Among the studied samples Sangiovese 2007 and Cabernet Franc 2006 and 2007 variety samples contained ∼23% and 15% of the total monomers

as gallocatechin, respectively. Epicatechin gallate was responsible for ∼6% of the free monomers quantified in this study. Among the proanthocyanidins oligomers, dimers B1 and B2 are present at higher concentrations in grapes and, consequently, in wine (Monagas et al., 2003). PA B1 was the main dimer in the wine samples, contributing with more than 60% of the dimers, as also reported in other studies (Cosme, Ricardo-da-Silva, & Laureano, 2009). PA B1 is the

main dimer in grape skins LDN-193189 manufacturer and during wine fermentation it is easier to extract than PA B2, present in high concentrations in seeds. Thus, for the varieties investigated, flavan-3-ols from grape skins contributed more to the wine flavan-3-ol composition, in agreement with results reported in the literature (Fernández, Kennedy, & Agosin, 2007). Merlot and Syrah wine samples showed the highest values for the sum of total monomers and dimers flavan-3-ols, especially for Merlot 2007 (118 mg L−1). Regarding percentage distribution, Cabernet Franc and Syrah wines, 2006 vintage, presented the highest monomer contents, followed by Sangiovese and Cabernet Franc, 2007 vintage, Merlot Screening Library purchase and Syrah, 2006 vintage, and Merlot and Syrah, 2007 vintage. The highest proportions of dimers were present in the samples of Merlot and Syrah from 2007 vintage (up to 51%), a finding previously observed in the Spanish wines Tempranillo, Graciano and Cabernet Sauvignon by Monagas et al. (2003). It is interesting to note

that both the vintage and Telomerase grape variety influenced the flavan-3-ol composition of the wines (p < 0.05), but with different behaviours according to the vintage. This was also observed by Chira et al. (2009), who evaluated, for two consecutive vintages, the tannin composition from the skin and seed extracts of Merlot and Cabernet Sauvignon grapes in Bordeaux, France. Grape and wine PAs are constituted of several oligomers and polymers with a very complex molecular structures. Phloroglucinolysis, which is the depolymerisation of PAs in an acid environment in the presence of phloroglucinol, gives access to important information regarding PA composition (Kennedy & Jones, 2001). Data on the PA structural composition of wine samples are shown in Table 3. Structurally, PAs present in wine samples comprised catechin, epicatechin, gallocatechin and epicatechin gallate as terminal and extension units, only gallocatechin not being detected as an extension unit (Table 3).

However, in Wong et al (2013), the available biomonitoring data

However, in Wong et al. (2013), the available biomonitoring data and intake estimates could not be simultaneously fitted by the model, possibly indicating that intakes had been underestimated in exposure pathway studies. Here we applied the Ritter model to two sets of cross-sectional data describing levels of ten PCBs and five OCPs in the Australian population. Intrinsic human elimination half-lives of PCBs and OCPs in the Australian population are estimated and compared with estimates for other populations, and at the

same time the historical intakes of PCBs and OCPs by the Australian population are reconstructed. The overall goal of this study is to further evaluate the possibility to extract information on intake and elimination from cross-sectional data by using a population level BMS-387032 price PK model. Two sets of cross-sectional data for PCBs and OCPs were obtained from studies selleckchem by the Department of Environment, Australia conducted

in 2003 and 2009 (Toms and Mueller, 2010). Pooled blood serum samples analyzed in the studies were stratified by age groups and gender. The youngest age group in 2003 was < 16 years where the mean age was 10 years and in 2009 was 0–4 years (followed by 5–15 years) where the mean age was 2 years. For both 2003 and 2009 the remaining age groups were 16–30, 31–45, 46–60 and > 60 years. Overall, the average age of individuals in the pools ranged from 10 to 76, and 2 to 74 years for the analysis in 2003 and 2009, respectively. As no significant difference between genders was observed for the chemicals of interest, we used concentrations measured in all pooled samples in

our analysis. The most prevalent PCB congeners detected in 2003 and 2009 were studied: PCB-74, PCB-99, PCB-118, PCB-138, PCB-146, PCB-153, PCB-156, Niclosamide PCB-170, PCB-180, and PCB-187. Five OCPs studied were: hexachlorobenzene (HCB), β-hexachlorocyclohexane (β-HCH), p,p′-dichlorodiphenyldichloroethylene (p,p′-DDE), p,p′-dichlorodiphenyltrichloroethane (p,p′-DDT), and trans-nonachlor (TNONA). Detailed information on sample collection, analysis and measured concentrations in the pooled samples is presented in section SI-1 of the Supplementary material. We calculated lipid-normalized whole-body concentrations of chemicals in representative individuals in the Australian population using the Ritter model. This approach implicitly assumes that the distribution of chemicals within body lipids is at equilibrium.

5, p < .005, ηp2 = 0.6 and F(5, 55) = 52.5, p < .001, ε = 0.5, ηp2 = 0.83 Ponatinib molecular weight respectively. However, there was a slight trend for a compatibility × chroma interaction, F(5, 55) = 2.4, p = .09, ε = 0.5, ηp2 = 0.18. Tukey post hoc tests revealed that the Simon effect was only reliable for 15% (p < .05) and 25% (p < .001) chroma levels.

A Bayesian ANOVA was further computed on mean RT in the same way as Experiment 1. The data favored the additive model M0 over the interactive model M1 by a Bayes factor of BF0,1 = 7.2 ± 0.61%, providing substantial support for additive effects ( Jeffreys, 1961). Best fitting Piéron’s law for each compatibly condition and observed mean RT are displayed in Fig. 6. As in Experiment 1, Piéron’s law describes the data well. The correlation

coefficients between observed and predicted data are very high, both at the group and the individual levels (see Table 2 and Table 3). The data was analyzed in the same way as Experiment 1. Pearson’s r values for each individual are generally lower compared to those observed in the Eriksen task (mean = 0.58, range 0.15–0.95; see Fig. 7A). A rapid look at the averaged data ( Fig. 7B) makes clear that Wagenmakers–Brown’s law is violated by the compatibility factor. As anticipated, the incompatible condition is associated with a smaller SD of RT compared to the compatible condition for each LEE011 mouse color saturation level. The linear mixed effects model with the lowest BIC index comprised by-subject random intercepts, and RT mean and compatibility as fixed factors. The interaction term was again removed, because 2-hydroxyphytanoyl-CoA lyase it was not significant and penalized the model. The effects of compatibility and mean RT were reliable (both MCMC p < .001). The best-fitting parameter

for the fixed effect of compatibility revealed that the intercept of Wagenmakers–Brown’s law was lowered by about 15 SD units in the incompatible condition (see Appendix C, for additional analyses leading to similar conclusions). The pattern of results from Experiment 2 is similar to that previously observed in the Eriksen task. Piéron and Wagenmakers–Brown laws hold for each S–R compatibility condition separately. The incompatible mapping lowers the intercept of the linear law by about 15 SD units, but does not affect its slope. Those results provide strong support for a common model framework between Eriksen and Simon tasks, and time-varying diffusion models appear likely candidates. While the DSTP is sufficiently abstract to be extended to different conflict tasks (Hübner et al., 2010), the SSP was specifically designed for spatial attentional control. However, White, Ratcliff, et al. (2011) hypothesized that the spotlight component of the SSP may also center on a more abstract feature space to account for non-spatial attentional effects in the Eriksen task (e.g., grouping effects).

We restrict our review to the tropics, where devising appropriate

We restrict our review to the tropics, where devising appropriate interventions to manage trees and tree genetic resources is important to meet international development goals of poverty alleviation and community

resilience (FAO, 2010 and Garrity, 2004). We learn more also restrict our consideration to three production categories: non-timber forest product (NTFP) harvesting (from natural, incipiently- and/or semi-domesticated forests and woodlands); agroforestry tree products (AFTPs) and services (provided by a wide range of mostly semi-domesticated local and exotic trees in smallholder-farm landscapes); and woody perennial commodity crops (which are often completely domesticated, exotic in major production centres, and grown in both smallholdings and larger plantations, though our concern here is only with the former). The boundaries between these production categories are not always easy to define, as evidenced, for example, by often subtle transitions in landscapes between forests Caspase inhibitor review and agroforests in a gradient of transformation and intensification (Balée, 2013, Michon, 2005 and Wiersum, 1997). In fact, one category often depends upon another for supporting sustainability, as, for example, many AFTPs

and tree commodity crops were once NTFPs, and often also still are (thus, the continued improvement of AFTP and tree commodity crop production may depend to a greater or lesser degree on accessing genetic resources Histamine H2 receptor maintained in natural stands; Hein and Gatzweiler, 2006, Mohan Jain and Priyadarshan, 2009 and Simons and Leakey, 2004). Our three production categories have received considerable attention for their roles in meeting development targets for small-scale harvesters and smallholder farmers in the tropics, both of which groups are the subject of our attention here (Belcher et al., 2005, Garrity, 2004 and Millard, 2011). Our categories are, however, not fully exhaustive of the benefits received by tropical rural communities from trees, as we do not, for example, consider the value of commercial

forest timber harvesting by local people (e.g., Menton et al., 2009). Nonetheless, the division into our three categories provides a useful way to structure the different benefits of trees to communities, to illustrate the issues faced in describing value and to determine appropriate interventions for improved management. Considering these different categories also demonstrates the importance of taking a wide view in determining where best to intervene for maximum impacts on livelihoods, for example, in minimising unintended consequences due to potentially negative interactions between different production systems (the same attention to interactions is important when promoting appropriate tree conservation interventions among a range of options, see Dawson et al., 2013).

5 ng) except that cycling was performed on a Mastercycler Nexus PCR Cycler with aluminium block (Eppendorf, Hamburg, Germany). The genotypes obtained were compared to those previously generated using the Investigator® buy R428 ESSplex Plus Kit [24]. For ChargeSwitch® purified samples, a standard 25 μL

Investigator® ESSplex Plus reaction volume with maximum of 15 μL of template DNA was used. Maxwell-extracted samples were amplified using a reduced 16.7 μL reaction volume with maximum of 10 μL of template DNA. Investigator® ESSplex Plus amplification reactions were performed with a standard 30 cycle protocol on a Mastercycler Nexus PCR Cycler with aluminium block except for an additional 3 min final extension step at 68 °C. One microliter of amplification product or allelic ladder was combined with 11.5 μL Hi-Di™ formamide and 0.5 μL of BTO Size Standard (Qiagen N.V., Venlo, Netherlands). Electrophoresis was done on an Applied Biosystems 3500xL Genetic Analyzer (injected at 3.0 kV for 8 s). The PowerPlex® ESI 17 Fast and ESX 17 Fast Systems were used to genotype

DNA from anonymous liquid blood samples from 656 unrelated individuals and 720 father and son pairs that were previously typed with the PowerPlex® ESX 17, ESI 17, and ESI 17 Pro Systems [5] and [25] along with six samples from the Standard Reference Materials 2391c, PCR Based DNA Profiling Standard and 10 samples from the Standard Reference Materials 2391b, PCR Based DNA Profiling Standard. Amplification products http://www.selleckchem.com/products/PD-98059.html were analyzed on an Applied Biosystems 3130xl Genetic Analyzer. All genotyping was performed with GeneMapper ID-X v1.4 software. Data tables were exported into Excel (Microsoft, Redmond, WA) and compared to data generated previously with the PowerPlex® ESX 17 and ESI17 Systems [25], and the Powerplex® ESI 17 Pro System [5]. N − 4 and N + 4 (N − 3 and N + 3 for D22S1045) stutter percentages

were calculated for all loci based on peak height from the data generated from unrelated individuals with the STR_StutterFreq Excel based software developed at NIST [26]. To ensure that data was not used from main allele peaks that were saturating, or where the main allele peak was too low and potentially in the stochastic range, BCKDHB stutter percentages were only calculated where the major allele was between 200 and 4000 RFU. In addition, to exclude contributions from N + 4 stutter that could artificially raise the height of the N − 4 stutter peak, N − 4 stutter was not calculated for alleles at heterozygous loci where the larger allele was two repeats away from the smaller allele at that locus. N − 2 stutter was calculated for D1S1656 and SE33. Full profiles were obtained in the presence of 0.5 mM EDTA for both the PowerPlex® ESI Fast and ESX Fast configurations (Supplemental Fig. 1). Signal decreased at all loci with increasing EDTA concentration for both configurations, except at vWA.

Globally, hundreds of thousands of persons are potentially expose

Globally, hundreds of thousands of persons are potentially exposed to rabies each year, and most require some form of PEP. The inability to perform diagnostic

evaluations of suspect animals thus results in inappropriate estimates of the level of vaccination required and major financial costs (Shwiff et al., 2013). From 20 to 40,000 people in the US may receive PEP each year (Christian et al., 2009), but post exposure care is scarce in resource-limited settings. In Tanzania, for example, where human rabies cases are greatly under-reported, the number of dog bites can be used to estimate the disease burden and monitor epidemiological trends (Cleaveland et al., 2002). Even when local facilities and infrastructure make diagnostic testing possible, the cost of even the simplest tests places a further burden on the health SCH 900776 in vitro system. Rabies diagnosis often requires costly and time-consuming procedures, such as the OIE-prescribed fluorescent antibody test (FAT), with the potential for a confirmatory diagnosis by virus isolation (Table 1). Although it is rapid, sensitive and specific, the FAT relies on expensive FITC-labeled anti-rabies antibodies and a fluorescence

selleck inhibitor microscope, often precluding its use in resource-limited settings. Virus isolation in tissue culture also requires laboratory capabilities that are usually unavailable where they are most needed. Fortunately, the direct, rapid immunohistochemical test (dRIT) for rabies now provides a more economical alternative to the FAT (Lembo et al., 2006). Simpler and less expensive diagnostic platforms are needed to enhance laboratory capacity in rabies-endemic regions

(Fooks et al., 2009). Experience from regions where Amoxicillin rabies has been eliminated shows that evidence-based diagnostic and surveillance strategies are needed to determine the distribution and prevalence of different lyssavirus species in Africa and Asia. Such strategies must involve the collation of animal disease data and its provision to public health authorities, to enable them to develop effective policies (Lembo et al., 2011 and Zinsstag et al., 2009). Once surveillance mechanisms are in place, it is essential to ensure the quality and reliability of the data and its dissemination within an expert network (Aylan et al., 2011). Importantly, effective surveillance permits early case reporting, which is vital for timely responses and informed decision-making. The combination of laboratory-based surveillance, enhanced public awareness and strategic utilization of potent, inexpensive vaccines is essential for rabies control and prevention (Murray and Aviso, 2012 and Fooks, 2005). Once established, an animal surveillance system can be customized and implemented to support the elimination of both canine and human rabies (Fooks et al., 2009 and Townsend et al., 2012).

4 We analyzed six standard fixation time measures (Rayner, 1998 a

4 We analyzed six standard fixation time measures (Rayner, 1998 and Rayner, 2009): first pass measures, such as probability of making a first-pass fixation, first fixation duration (the duration of the first fixation on the target, regardless of how many fixations are made), single fixation duration (the duration of a fixation on the target when only one fixation is made), gaze duration (the sum of the duration of all fixations made on the target Small molecule high throughput screening before leaving it),

as well as later measures, such as total viewing time (the sum of all fixations on the target, including rereading of it after first-pass reading) and go-past time (the sum of the duration of all fixations on the target and any rereading of words to the left of it until the target is passed to the right). In addition, we also analyzed the probability of regressing into the target and the probability of regressing out of the target. To assess how subjects approached the task of proofreading, we analyzed reading time measures on target words that did not contain an error (in either the reading or proofreading block) but did contain either a frequency (e.g., “The inner components are protected by a black metal/alloy increasing its lifespan.”) BYL719 nmr or predictability manipulation (e.g., “The skilled gardener went outside to pull up the weeds/roses along the driveway.”).

We analyzed local reading measures on the target words presented in italics above (but not presented in italics in the experiment; means and standard errors are in Table 4). For the following analyses, task (reading vs. proofreading) and independent variable (high vs. low) were entered as fixed effects in the LMMs. The LMMs were fit separately for frequency items and predictability

items (except for test of the three-way interaction, see Section 2.2.2.3). An interaction between independent variable (high vs. low frequency or high vs. low predictability) and task (reading vs. proofreading) would indicate that subjects were changing their sensitivity to these word properties Thalidomide in order to perform the task. Results of the linear mixed effects analyses on fixation time measures are reported in Table 5. There was a significant effect of task for all fixation time measures for sentences with a frequency manipulation (single fixation duration: b = 8.86, t = 2.35; gaze duration: b = 14.71, t = 32.80; total time: b = 34.25, t = 4.63; go-past time: 34.79, t = 4.77) with the exception of first fixation duration (b = 4.26, t = 1.13) and for sentences with a predictability manipulation (first fixation duration: b = 12.17, t = 3.79; single fixation duration: b = 13.53, t = 3.93; gaze duration: b = 14.15, t = 3.08; total time: b = 28.02, t = 3.68; go-past time: 17.97, t = 2.57), indicating that, when checking for nonword errors subjects spent longer on target words throughout their encounter with them (i.e., across all eye movement measures).

Given the absence of viable environmental data within the catchme

Given the absence of viable environmental data within the catchment before the LACM Spill of 2009, two control methods were implemented (mining-free tributaries and floodplain depth), following other similar contaminant studies (Mackay et al., 2013, Parry, 2000 and Taylor and Hudson-Edwards, 2008). Background samples revealed that Cu levels in the channel and floodplain were higher relative to both the tributary and floodplain depth control. Furthermore, Cr in the channel and Cr and Pb in the floodplain were shown to be elevated with respect to equivalent floodplain depth selleck (10–50 cm) sediment-metal

concentrations. This elevation was not supported by the tributary control, which is unusual given that this is evident in the Cu data and that selleck chemicals one would expect similarity between these two controls. The small sample size (n = 2) of the tributary control, which was a function of time and funding constraints, limits the comparative and statistical power resulting in the occurrence of a type 2 statistical error. This limitation is counteracted, however, by the use of the 19 proxy background samples taken at depth from the Saga and Inca creek floodplain systems ( Table 4), eliminating reliance on the tributary controls

as the single measure of background sediment-metal values. Comparing the results to ANZECC and ARMCANZ (2000), ISQG – low guidelines and CCME (2007) Soil Guidelines revealed minor elevations of As and Cr in the channel as well as As on the floodplain surface (0–2 cm). Copper values within channel samples and floodplain Thiamet G surface (0–2 cm) samples exceeded ANZECC and ARMCANZ (2000), ISQG – low Cu guideline, Canadian Guideline for Cu (CCME, 2007) and the ANZECC and ARMCANZ (2000) ISQG – high Cu guideline (Table 1 and Table 2). The application of total extractable metal concentration as a measure of contamination has been utilised in many Australian studies evaluating

the impact of mining on the environment (e.g. Gore et al., 2007, Lottermoser et al., 1999, Mudd and Patterson, 2010 and Taylor et al., 2010). It is also a recommended approach in Australian soil and sediment guidelines (e.g. ANZECC and ARMCANZ, 2000, NEPC, 1999a and NEPC, 1999b) and international guidelines (e.g. CCME, 2002, CCME, 2007 and NOAA, 1999). A growing number of studies, however, are focusing more on how metals are held within sediment, their extractability, bioaccessibility and metal speciation (Chopin and Alloway, 2007, Lui et al., 2003, Mackay et al., 2011, Noller et al., 2009, Sastre et al., 2004, Smith et al., 2009 and Taylor and Kesterton, 2002). Indeed, the ANZECC guidelines advocate trigger values for total extractable metals should be used first to assess a potential environmental problem followed by further investigation if values are found to exceed trigger values (ANZECC and ARMCANZ, 2000).
