In 2001 the Queensland coal industry consolidated on record expansion in the export market over the past two years and again, increased its sales to overseas customers. New sales records were set in both the export and domestic markets. Unprecedented international demand for Queensland metallurgical coals coupled with improved prices and a favourable A$-US$ exchange rate created strong market conditions for the Queensland coal export industry, boosting confidence for further expansion and new developments. Australian coal exports in 2001 amounted to 194 Mt and are forecast to reach 275 million tonnes per annum (Mtpa) in 2020. The Queensland coal industry is poised to capture a significant share of this market growth. Queensland's large inventory of identified coal, currently estimated at more than 37 billion tonnes (raw coal m situ), is adequate to sustain the industry for many years and allow new opencut and underground mines to develop according to future market demand. Recent coal exploration successes are expected to add significant tonnage to the inventory (Coxhead, Smith and Coffey, 2002). Most of the coal exported from Queensland is mined in the Bowen Basin of central Queensland and additional tonnage of Walloon coal is exported by mines in the Moreton Basin and Surat Basin in south-east Queensland. The Walloon Coal Measures and its equivalents contain large resources of undeveloped opencut, high volatile, clean-burning thermal coal. The environmental advantages in the utilisation of these coals are now recognised and strong growth in production is expected in the near future for supply to both the domestic and export markets. Establishment of new rail transport and civil infrastructure will however, be required to support the development of large scale mining operations in this region

Ninety-three giant Queensland grouper, Epinephelus lanceolatus (Bloch), were found dead in Queensland, Australia, from 2007 to 2011. Most dead fish occurred in northern Queensland, with a peak of mortalities in Cairns in June 2008. In 2009, sick wild fish including giant sea catfish, Arius thalassinus (Rüppell), and javelin grunter, Pomadasys kaakan (Cuvier), also occurred in Cairns. In 2009 and 2010, two disease epizootics involving wild stingrays occurred at Sea World marine aquarium. Necropsy, histopathology, bacteriology and PCR determined that the cause of deaths of 12 giant Queensland grouper, three wild fish, six estuary rays, Dasyatis fluviorum (Ogilby), one mangrove whipray, Himantura granulata (Macleay), and one eastern shovelnose ray, Aptychotrema rostrata (Shaw), was Streptococcus agalactiae septicaemia. Biochemical testing of 34 S. agalactiae isolates from giant Queensland grouper, wild fish and stingrays showed all had identical biochemical profiles. The 16S rRNA gene sequences of isolates confirmed all isolates were S. agalactiae; genotyping of selected S. agalactiae isolates showed the isolates from giant Queensland grouper were serotype Ib, whereas isolates from wild fish and stingrays closely resembled serotype II. This is the first report of S. agalactiae from wild giant Queensland grouper and other wild tropical fish and stingray species in Queensland, Australia. © 2012 Blackwell Publishing Ltd and State of Queensland.

To determine whether there is an excess risk of breast cancer among female employees of the Australian Broadcasting Corporation (ABC), especially outside Queensland, compared with women in the general populations of the states and territories. We used an occupational cohort design. Information from ABC staff records was linked with data from state and territory cancer registries to identify female employees of the ABC with an incident, histologically confirmed breast cancer. Data linkage was complemented by a self-report method. We included a cohort of ABC female employees who had developed breast cancer at any time between 1994 and 2005, during their employment or after cessation of employment with the ABC. The standardised incidence ratio (SIR) was calculated as the number of women at the ABC observed with breast cancer divided by the expected number based on population rates in each state and territory. Tests for heterogeneity were performed to examine the variation of breast cancer risk between states and territories. Out of 5969 women who were permanently employed either part-time or full-time at the ABC between 1994 and 2005, 48 eligible women with breast cancer were identified. An excess risk of breast cancer among ABC female employees in Queensland (identified in an earlier study) was reconfirmed. No excess risk of breast cancer was observed among ABC staff diagnosed in states outside Queensland (SIR, 1.01 [95% CI, 0.72-1.38]), or in Australia as a whole (including Queensland) (SIR, 1.12 [95% CI, 0.83-1.49]). There was no significant heterogeneity in breast cancer risk among states and territories once Queensland was excluded from the analysis (P = 0.39). No statistically significant excess risk of breast cancer in ABC female employees was found across the Australian states and territories as a whole compared with their respective population incidences. A statistically significant increased risk of breast cancer was found among ABC female employees in

Mating-induced changes in olfactory-mediated behavior of laboratory-reared normal, sterile, and wild female Mediterranean fruit flies (Diptera: Tephritidae) mated to conspecific males

International Nuclear Information System (INIS)

1998-01-01

Laboratory-reared normal, sterile, and wild female Mediterranean fruit flies, Ceratitis capitata (Wiedemann), were mated with laboratory-reared normal, sterile, and wild male flies to assess the ability of males to alter olfactory-mediated behavioral responses of females to male-produced pheromone or host fruit odor. Virgin females of all 3 types showed a preferential attraction and arrestment on yellow spheres emitting male-produced pheromone in a laboratory flight tunnel. Laboratory-reared normal and wild females mated to laboratory reared normal, sterile, or wild males switched their behavior showing strong preferential attraction to, arrestment on, and egg-laying in (for laboratory-reared females) yellow spheres emitting host fruit odor (guava) over male-produced pheromone. Sterile females did not show a significant switch in behavior except when mated to sterile males. The olfactory-mediated behavioral switch was most evident in the laboratory-reared normal female × laboratory-reared normal male mating. These findings suggest that irradiation of males inducing gamete sterility does not affect the factor(s) from the male accessory gland associated with altering female olfactory behavior. The ability of sterile males to alter adequately olfactory-mediated behavior of wild females is discussed in the context of the sterile insect technique for control of Mediterranean fruit flies in the field

Natural gas and electricity generation in Queensland

International Nuclear Information System (INIS)

Webb, G.

2001-01-01

The focus of this article is on electricity generation in Queensland. Black coal accounted for 97 percent, while natural gas made up only 1 percent of the fuel used in thermal power generation in 1997-98. The share of natural gas in thermal electricity generation is expected to rise to 21 percent by 2014-2015, because of the emphasis on natural gas in Queensland's new energy policy. Since 1973-1974, Queensland has led the way in electricity consumption, with an average annual growth rate of 6.8 percent but the average thermal efficiency has fallen from 38.0 percent in 1991-1992, to 36.6 percent in 1997-1998

Ross River virus (RRV) infection is a debilitating disease that has a significant impact on population health, economic productivity, and tourism in Australia. This study examined epidemiologic patterns of RRV disease in Queensland, Australia, during January 2001-December 2011 at a statistical local area level. Spatio-temporal analyses were used to identify the patterns of the disease distribution over time stratified by age, sex, and space. The results show that the mean annual incidence was 54 per 100,000 persons, with a male:female ratio of 1:1.1. Two space-time clusters were identified: the areas adjacent to Townsville, on the eastern coast of Queensland, and the southeast areas. Thus, although public health intervention should be considered across all areas in which RRV occurs, it should specifically focus on high-risk regions, particularly during summer and autumn to reduce the social and economic impacts of RRV infection. © The American Society of Tropical Medicine and Hygiene.

2013-03-01

Throughout December 2010 and January 2011, Queensland experienced widespread flooding due to unusually protracted and heavy rainfalls. In mid-January 2011, four individuals from a small community in Central Queensland were hospitalized with leptospirosis. A further five cases were subsequently identified from around Central Queensland, bringing the total to nine. Microscopic agglutination testing found that serovar Arborea (Leptospira borgpetersenii serovar Arborea) was presumptively responsible for leptospirosis in seven of nine confirmed cases. Serovars Hardjo and Australis were identified in samples from two remaining cases. All cases had exposure to flood water. No single exposure source was identified. This is the first reported outbreak of leptospirosis in Central Queensland and the first report of leptospirosis cases associated with flood water inundation in Queensland. Public health authorities should continue to promote awareness of leptospirosis in flood-affected populations. Healthcare providers must maintain a high level of suspicion for leptospirosis during and after flood events.

"I love a sunburnt country, A land of sweeping plains, Of ragged mountain ranges, Of droughts and flooding rains. I love her far horizons, I love her jewel-sea, Her beauty and her terror, The wide brown land for me." (Dorothea Mackellar OBE, 1885-1968). This second stanza from Mackellar's famous poem "My Country", beautifully sums up the Australian environment. In late 2010-early 2011, the "droughts and flooding rains" were the perfect terms to describe the climatic variability and the resulting flooding impacts experienced in many parts of Queensland under an enhanced La Niña as part of the ENSO (El Niño-Southern Oscillation) climate pattern, with over 75% of Queensland being declared a disaster zone. This contrasts with the severe drought that had gripped many parts of Australia over the previous 8 years which saw water storage levels plummet, and resulted in 35% of Queensland being 'drought declared' as at April 2010. On the Darling Downs in southern Queensland, over 100,000 ha of land was inundated by the Condamine River due to flooding in early 2011. The river which is generally rule throughout mainland Australia. The Queensland floods highlight the pressing and urgent need for an accurate and more intensive network of river gauging and sediment monitoring. In a country of "droughts and flooding rains" and in the face of climate change, this need is now imperative.

Analysis of the Mediterranean fruit fly [Ceratitis capitata (Wiedemann)] spatio-temporal distribution in relation to sex and female mating status for precision IPM.

The Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann), is a key pest of fruit crops in many tropical, subtropical and mild temperate areas worldwide. The economic importance of this fruit fly is increasing due to its invasion of new geographical areas. Efficient control and eradication efforts require adequate information regarding C. capitata adults in relation to environmental and physiological cues. This would allow effective characterisation of the population spatio-temporal dynamic of the C. capitata population at both the orchard level and the area-wide landscape. The aim of this study was to analyse population patterns of adult medflies caught using two trapping systems in a peach orchard located in central Italy. They were differentiated by adult sex (males or females) and mating status of females (unmated or mated females) to determine the spatio-temporal dynamic and evaluate the effect of cultivar and chemical treatments on trap catches. Female mating status was assessed by spermathecal dissection and a blind test was carried out to evaluate the reliability of the technique. Geostatistical methods, variogram and kriging, were used to produce distributional maps. Results showed a strong correlation between the distribution of males and unmated females, whereas males versus mated females and unmated females versus mated females showed a lower correlation. Both cultivar and chemical treatments had significant effects on trap catches, showing associations with sex and female mating status. Medfly adults showed aggregated distributions in the experimental field, but hot spots locations varied. The spatial pattern of unmated females reflected that of males, whereas mated females were largely distributed around ripening or ripe fruit. The results give relevant insights into pest management. Mated females may be distributed differently to unmated females and the identification of male hot spots through monitoring would allow localisation of virgin

Economic feasibility of fruit and vegetable irradiation in Australia

Beattie, B.B.; Wiblin, B.

1983-01-01

The cost of treatment of fruit and vegetables in an Ionising Radiation Treatment (IRT) facility can be quite low. However, other circumstances mitigate against its overall economic feasibility. Research has determined that irradiation treatments are technically successful in three general areas. These are: prevention of fungal wastage in strawberries, prevention of sprouting in potatoes and onions, and disinfestation of fruit and vegetables from insect pests. The strawberry industry in Australia is very small and marketing of the crop will continue regardless of the availability of an IRT facility. On the other hand the potato industry is large but does not see sprouting as a marketing problem. The third area is disinfestation against Queensland fruit fly for interstate and export markets. Recent changes in Victorian quarantine legislation give a much greater number of alternatives for produce going into that State

When not to copy: female fruit flies use sophisticated public information to avoid mated males

Semen limitation (lack of semen to fertilize all of a female's eggs) imposes high fitness costs to female partners. Females should therefore avoid mating with semen-limited males. This can be achieved by using public information extracted from watching individual males' previous copulating activities. This adaptive preference should be flexible given that semen limitation is temporary. We first demonstrate that the number of offspring produced by males Drosophila melanogaster gradually decreases over successive copulations. We then show that females avoid mating with males they just watched copulating and that visual public cues are sufficient to elicit this response. Finally, after males were given the time to replenish their sperm reserves, females did not avoid the males they previously saw copulating anymore. These results suggest that female fruit flies may have evolved sophisticated behavioural processes of resistance to semen-limited males, and demonstrate unsuspected adaptive context-dependent mate choice in an invertebrate.

Coal seam has boom - powering North Queensland industrial growth

Reduced operating costs, lower greenhouse gas emissions and security of supply are being cited by North Queensland industry leaders as the reasons for investing more than A$550 million to expand operations and convert to coal seam gas as their preferred fuel source. The article, by Enertrade, reports that just a few months after commissioning its North Queensland Gas Pipeline to transport coal seam gas from Moranbah to Townsville, Enertrade has signed contracts that will see combined cycle gas-fired baseload electricity generated in Townsville and the Queensland Nickel Refinery, and Xstrata Copper Refinery switch from liquid fuels to gas. The development has been driven by state government policy that 13% of Queensland's electricity be sourced from gas-fired power generation from 1 January 2005.

Austrolecanium cryptocaryae Lin & Cook sp. n. is described based on adult female morphology and DNA sequences from mitochondrial and nuclear loci. This Australian endemic species was found on the underside of leaves of Cryptocarya microneura (Lauraceae) in Queensland. All phylogenetic analyses of four independent DNA loci and a concatenated dataset show that A. cryptocaryae is monophyletic and closely related to A. sassafras Gullan & Hodgson, the type species of Austrolecanium Gullan & Hodgson. The adult female of A. cryptocaryae is described and illustrated and a table is provided of the characters that differ among adult females of the three species of Austrolecanium currently recognised (A. cappari (Froggatt), A. cryptocaryae sp. n. and A. sassafras).

Accessing Queensland's soil information - an open data revolution!

Science.gov (United States)

Bryant, Kelly; O'Brien, Lauren; Brough, Daniel

2015-07-01

The Queensland government is the custodian of soil and land resource information with an estimated value of 75 million. The Soil and Land Information (SALI) system houses this data from over 600 distinct studies with some 96,000 soil observations dating back to the 1940s. This data is now not only used by government but by universities, councils, landowners, consultants and schools. Providing this information to the public in an easy and accessible way, with a focus towards online delivery is crucial. Previous issues with distribution of online soils information in Queensland have stemmed not only from limits to technology but also, changing departmental structures and multiple websites. The department which manages soils information in Queensland has undergone nine name changes in the last 12 years due to Machinery of Government (MoG) restructures. This constantly changing web presence and branding is as confusing for people sourcing soils information as it is for those providing it. The Queensland government has now moved to a whole of government online environment. This is a single website with no reference to the convoluted structures within government or department names. The aim is to prevent impacts from future MoG changes on the provision of data and information to the public. Queensland government soils now has a single dedicated website (qld.gov.au/environment/land/soil) which has allowed us to start to build a repository for soils information and is a single portal for people to access soils data. It has been demonstrated that this consistent approach to websites improves trust and confidence of users [1] and from this, confidence in using Queensland soils information and data and ultimately better land management decisions.

Radiation oncology medical physics education and training in Queensland

Full text: The training education and accreditation program (TEAP) for radiation oncology commenced formally in Queensland in 2008 with an initial intake of nine registrars. In 2011 there are 17 registrars across four ACPSEM accredited Queensland Health departments (Mater Radiation Oncology Centre, Princess Alexandria Hospital, Royal Brisbane and Women's Hospital, Townsville Hospital). The Queensland Statewide Cancer Services Plan 2008-2017 outlines significant expansion to oncology services including increases in total number of treatment machines from 14 (2007) to 29-31 (2017) across existing and new clinical departments. A direct implication of this will be the number of qualified ROMPs needed to maintain and develop medical physics services. This presentation will outline ongoing work in the ROMP education and Training portfolio to develop, facilitate and provide training activities for ROMPs undertaking TEAP in the Queensland public system. Initiatives such as Department of Health and Aging scholarships for medical physics students, and the educational challenges associated with competency attainment will also be discussed in greater detail.

Root caries stands to be a significant burden for Australia's ageing population. The objective of this study was to describe Queensland dental practitioners' perceptions of root caries prevalence, presentation and predisposing factors as well as diagnosis and recording practices. Using the Queensland Dental Board register, all 2,515 dentists and dental specialists practising in Queensland were invited to participate in a questionnaire-based postal survey. Of the 660 responses received, 638 were included for final analysis. Use of diagnostic measures such as surface elasticity and contour were reported frequently. A majority of respondents (77%) reported not recording root caries in a way that could be distinguished from coronal caries. Dietary analysis was the most commonly reported adjunctive aid for risk assessment. Recommendations for use of remineralizing agents were frequently reported (home use 90%; in office use 71%). Salivary impairment was reported to be an important risk factor for root caries by 93% of respondents, but only 18% reported performing salivary analysis. A large proportion of respondents (32%) considered patients with diabetes to be of low or no risk of root caries. While the Queensland dental practitioners who participated in this survey demonstrated an awareness of root caries and its predisposing factors, clinical risk assessment particularly for patients with diabetes should be further examined. © 2013 John Wiley & Sons A/S.

Strong growth for Queensland mining

Energy Technology Data Exchange (ETDEWEB)

1990-10-01

The Queensland mining industry experienced strong growth during 1989-90 as shown in the latest statistics released by the Department of Resource Industries. The total value of Queensland mineral and energy production rose to a new record of $5.1 billion, an increase of 16.5% on 1988-89 production. A major contributing factor was a 20.9 percent increase in the value of coal production. While the quantity of coal produced rose only 1.1 percent, the substantial increase in the value of coal production is attributable to higher coal prices negotiated for export contracts. In Australian dollar terms coal, gold, lead, zinc and crude oil on average experienced higher international prices than in the previous year. Only copper and silver prices declined. 3 tabs.

Healthcare providers' beliefs may play a role in the outcome of whiplash-associated disorders (WAD), a condition which is proposed to be culturally dependent. Clinical practice guidelines recommend an active approach for the management of WAD, which is often delivered by physiotherapists. However, there is no data on physiotherapists' whiplash beliefs. Our primary objective was to determine physiotherapists' beliefs from Queensland (Australia) and Singapore, two cultures with differing prevalence of chronic musculoskeletal pain and chronic WAD. A pen and paper survey of musculoskeletal physiotherapists practicing in Queensland and Singapore was conducted. Participants completed questionnaires consisting of patient vignettes and statements inquiring knowledge and attitudes towards WAD. Chi-square tests of significance were used to compare the responses of physiotherapists from both samples. Ninety-one (response rate 45%) Queensland-based and 94 (response rate 98%) Singapore-based physiotherapists participated in the study. The beliefs in the management strategies for the patient vignettes were generally consistent with practice guidelines. A higher proportion of Queensland-based physiotherapists expected permanent disabilities for the patient vignette depicting chronic WAD (Queensland: 55% Singapore: 28% Pearson chi-sq 18.76, p Queensland and Singapore were similar but there were specific differences. Physiotherapists' whiplash beliefs in Queensland and Singapore did not clearly reflect the difference in prevalence of chronic musculoskeletal pain or chronic WAD in Queensland and Singapore.

Queensland's proposed surrogacy legislation: an opportunity for national reform.

Science.gov (United States)

Johnson, Tammy

2010-02-01

Surrogacy has existed since Biblical times when Hagar, the maidservant of the infertile Sarah, acted as a surrogate to bear Sarah and her husband, Abraham, a son. Despite the longevity of the practice of surrogacy, modern society has been reluctant to embrace surrogacy arrangements due to the ethical and sometimes practical debates they spark. This reluctance is evidenced by the general lack of legislative support for surrogacy arrangements in Australia and worldwide. In 2009 it was announced that Queensland will decriminalise altruistic surrogacy. While this decision is a step towards bringing Queensland in line with other Australian jurisdictions, it also has the potential to open up a Pandora's Box of legal and ethical issues. This article provides a snapshot of the anticipated new Queensland surrogacy legislation together with a brief overview of the regulation of surrogacy in all Australian jurisdictions. Recommendations are made as to whether there is a need for further reform of surrogacy regulation in certain Australian jurisdictions and if so, whether the proposed Queensland legislation constitutes an appropriate model on which to base such reform.

The oriental fruit fly, Bactrocera dorsalis, is an economically damaging, polyphagous pest of fruit crops in South-East Asia and Hawaii, and a quarantine pest in other parts of the world. The objective of our study was to identify new attractants for B. dorsalis from overripe mango fruits. Headspace samples of volatiles were collected from two cultivars of mango, 'Alphonso' and 'Chausa', and a strong positive behavioral response was observed when female B. dorsalis were exposed to these volatiles in olfactometer bioassays. Coupled GC-EAG with female B. dorsalis revealed 7 compounds from 'Alphonso' headspace and 15 compounds from 'Chausa' headspace that elicited an EAG response. The EAG-active compounds, from 'Alphonso', were identified, using GC-MS, as heptane, myrcene, (Z)-ocimene, (E)-ocimene, allo-ocimene, (Z)-myroxide, and γ-octalactone, with the two ocimene isomers being the dominant compounds. The EAG-active compounds from 'Chausa' were 3-hydroxy-2-butanone, 3-methyl-1-butanol, ethyl butanoate, ethyl methacrylate, ethyl crotonate, ethyl tiglate, 1-octen-3-ol, ethyl hexanoate, 3-carene, p-cymene, ethyl sorbate, α-terpinolene, phenyl ethyl alcohol, ethyl octanoate, and benzothiazole. Individual compounds were significantly attractive when a standard dose (1 μg on filter paper) was tested in the olfactometer. Furthermore, synthetic blends with the same concentration and ratio of compounds as in the natural headspace samples were highly attractive (P < 0.001), and in a choice test, fruit flies did not show any preference for the natural samples over the synthetic blends. Results are discussed in relation to developing a lure for female B. dorsalis to bait traps with.

There is a paucity of data pertaining to the incidence of biopsy-proven glomerulonephritis (GN) in Australia. This retrospective study aims to review the data from all adult native renal biopsies performed in the state of Queensland from 2002 to 2011--comparing results with centres from across the world. Pathology reports of 3697 adult native kidney biopsies were reviewed, of which 2048 had GN diagnoses. Age, gender, clinical indication and histopathology findings were compared. The average age at biopsy was 48 ± 17 years. Male preponderance was noted overall (∼60%), with lupus nephritis being the only individual GN with female predilection. The average rate of biopsy was 12.04 per hundred thousand people per year (php/yr). Nephrotic and nephritic syndromes comprised approximately 75% of all clinical indications that lead to GN diagnoses. IgA nephropathy (1.41 php/yr) was the most common primary GN followed by focal segmental glomerulosclerosis (1.02 php/yr) and crescentic GN (0.73 php/yr). Diabetic nephropathy (0.84 php/yr), lupus nephritis (0.69 php/yr) and amyloidosis (0.19 php/yr) were the most commonly identified secondary GN. IgA nephropathy is the predominant primary GN in Queensland, and nephrotic syndrome the most common indication for a renal biopsy. While crescentic GN incidence has significantly increased with time, focal segmental glomerulosclerosis incidence has not shown any trend. Incidence of GN overall appears to increase with age. The annual rate of biopsy in this study appears lower than previously published in an Australian population. © 2015 Asian Pacific Society of Nephrology.

Among patients with invasive melanoma, females are known to have higher survival than males globally. However, this survival advantage has not been explored in thin melanomas, the most common form of the disease. In addition, it is unclear if this advantage is true across all age groups. We aimed to compare melanoma survival between males and females by clinical stage and within age groups. Melanomas from 1995 to 2008 were extracted from the Queensland Cancer Registry and the Surveillance, Epidemiology, and End Results (SEER) Program, and melanoma-specific deaths were ascertained up to 2011. Flexible parametric survival models compared survival between groups. The Queensland cohort of 28,979 patients experienced 1712 melanoma deaths and the SEER cohort of 57,402 patients included 6929 melanoma deaths. Survival rates were in favour of females across nearly all tumour stages, including thin invasive tumours in both cohorts after adjusting for demographic and clinical factors [odds ratio (OR) death female:male for stage I melanoma = 0.64 in Queensland; and OR = 0.79 in the US, both P age categories. In particular, the survival advantage was inconsistent in females with stage I melanoma aged under 60. Females with melanoma have a survival advantage over males including in stage I melanomas. However, this advantage is dependent on age at diagnosis, suggesting an underlying biological mechanism influenced by age that exists from the very early stages of the disease.

To examine differences between Queensland and Victorian coding of hospital-acquired conditions and suggest ways to improve the usefulness of these data in the monitoring of patient safety events. Secondary analysis of admitted patient episode data collected in Queensland and Victoria. Comparison of depth of coding, and patterns in the coding of ten commonly coded complications of five elective procedures. Comparison of the mean complication codes assigned per episode revealed Victoria assigns more valid codes than Queensland for all procedures, with the difference between the states being significantly different in all cases. The proportion of the codes flagged as complications was consistently lower for Queensland when comparing 10 common complications for each of the five selected elective procedures. The estimated complication rates for the five procedures showed Victoria to have an apparently higher complication rate than Queensland for 35 of the 50 complications examined. Our findings demonstrate that the coding of complications is more comprehensive in Victoria than in Queensland. It is known that inconsistencies exist between states in routine hospital data quality. Comparative use of patient safety indicators should be viewed with caution until standards are improved across Australia. More exploration of data quality issues is needed to identify areas for improvement.

The epidemiology of infections with nontuberculous mycobacteria (NTM) has been changing and the incidence has been increasing in some settings. The main route of transmission to humans is considered to be from the environment. We aimed to describe spatial clusters of cases of NTM infections and to identify associated climatic, environmental and socio-economic variables. NTM data were obtained from the Queensland Mycobacterial Reference Laboratory for the period 2001-2011. A Bayesian spatial conditional autoregressive model was constructed at the postcode level, with covariates including soil variables, maximum, mean and minimum rainfall and temperature, income (proportion of population earning Queensland region overlying the Surat sub-division of the Great Artesian Basin, as well as in the lower North Queensland Local Government Area known as the Whitsunday region. Our models estimated an expected increase of 21% per percentage increase of population earning Queensland, and a number of socio-ecological, economic and environmental factors were found to be associated with NTM infection risk.

To investigate and describe the relationship between indigenous Australian populations, residential aged care services, and community-onset Staphylococcus aureus bacteremia (SAB) among patients admitted to public hospitals in Queensland, Australia. Ecological study. We used administrative healthcare data linked to microbiology results from patients with SAB admitted to Queensland public hospitals from 2005 through 2010 to identify community-onset infections. Data about indigenous Australian population and residential aged care services at the local government area level were obtained from the Queensland Office of Economic and Statistical Research. Associations between community-onset SAB and indigenous Australian population and residential aged care services were calculated using Poisson regression models in a Bayesian framework. Choropleth maps were used to describe the spatial patterns of SAB risk. We observed a 21% increase in relative risk (RR) of bacteremia with methicillin-susceptible S. aureus (MSSA; RR, 1.21 [95% credible interval, 1.15-1.26]) and a 24% increase in RR with nonmultiresistant methicillin-resistant S. aureus (nmMRSA; RR, 1.24 [95% credible interval, 1.13-1.34]) with a 10% increase in the indigenous Australian population proportion. There was no significant association between RR of SAB and the number of residential aged care services. Areas with the highest RR for nmMRSA and MSSA bacteremia were identified in the northern and western regions of Queensland. The RR of community-onset SAB varied spatially across Queensland. There was increased RR of community-onset SAB with nmMRSA and MSSA in areas of Queensland with increased indigenous population proportions. Additional research should be undertaken to understand other factors that increase the risk of infection due to this organism.

Waste generated from construction and building demolition work constitutes about 68% of all solid waste generated each year in South East Queensland. Consequently, it has created a serious waste management problem. The State Governments of Victoria and New South Wales have been encouraging the use of recycled materials from construction and related waste; they have also promulgated specifications for their use. In Queensland, however, similar regulations are not anticipated in the near future, which explains the lack of funded research conducted in this important arena. This paper presents an evaluation of the prevailing waste recycling practices in Queensland. Nine sites were visited, including two construction sites, three demolition sites, three recycling plants and one landfill in South East Queensland. The difficulties encountered by the recycling programme operators and their associates at these sites are described and the benefits of recycling construction materials are presented. One of the major barriers is that the local councils disallow the use of recycled materials in new construction work. To help rectify these impediments to recycling, recommendations are given to increase the use of recycled construction waste in South East Queensland.

Kisely, Steve; Pais, Joanne

2011-07-01

The Australian Government has provided $20 million to establish the Population Health Research Network (PHRN), with representation from all States and Territories to facilitate population health research through data linkage. Health LinQ is part of the Queensland node involving four Queensland universities, Queensland Health and the Australian e-Health Research Centre. This paper reviews the potential for using administrative databases to study the mental health experience of Indigenous Queenslanders. Researchers can define cohorts for study within the administrative data or link them to their own data. Robust protocols preserve confidentiality so that researchers only receive anonymized data. Indigenous status can be defined either through place of residence or through the recording of Indigenous status in datasets such as the Queensland Hospital Admitted Patient Data Collection. Available data include hospital morbidity, mental health data and mortality. Indigenous status is correctly identified in about 89% of cases with variation by definition used. Administrative data provide researchers and decision makers with accessible, cost-effective information without the intrusion and cost of additional data collection. These techniques are especially useful in studying regional, rural and remote populations where access may be difficult.

2013-01-01

Various temporal patterns of suicide events, according to time of day, day of week, month and season, have been identified. However, whether different dimensions of time interact has not been investigated. Using suicide data from Queensland, Australia, this study aims to verify if there is an interaction effect between seasonal and day-of-the-week distribution. Computerized suicide data from the Queensland Suicide Register for those aged 15+ years were analyzed according to date of death, age, sex and geographic location for the period 1996–2007. To examine seasonal differences in day-of-the-week pattern of suicide, Poisson regressions were used. A total of 6,555 suicides were recorded over the whole study period. Regardless of the season, male residents of Brisbane had a significantly marked day-of-the-week pattern of suicide, with higher rates between Mondays and Thursdays. When seasonal differences were considered, male residents in Brisbane showed a Monday peak in summer and a wave-shape pattern with a peak on Thursday and a nadir on Saturdays in winter. Whilst males have distinctive peaks in terms of days of the week for summer and winter, females do not show similar patterns. PMID:23880724

Globally, suicide rates increase with age, being highest in older adults. This study analyzed differences in suicides in older adults (65 years and over) compared to middle-aged adults (35-64 years) in Queensland, Australia, during the years 2000-2012. The Queensland Suicide Register was utilized for the analysis. Annual suicide rates were calculated by gender and age group, and odds ratios with 95% confidence intervals were examined. In Queensland, the average annual rate of suicides for older adults was 15.27 per 100,000 persons compared to 18.77 in middle-aged adults in 2000-2012. There were no significant changes in time trends for older adults in 2002-2012. Suicide methods differed between gender and age groups. Older adults who died by suicide were more likely to be male, widowed, living alone or in a nursing home, and out of the work force. The prevalence of untreated psychiatric conditions, diagnosed psychiatric disorders, and consultations with a mental health professional three months prior to death was lower in older adults than middle-aged adults. Somatic illness, bereavement, and attention to suicide in the media were more common among older adults than middle-age adults. Older females were particularly more likely to pay attention to suicide in the media. Our findings show older adults who died by suicide were more likely to experience somatic illnesses, bereavement, and pay attention to suicide in the media compared to middle aged. Preventing suicide in older adults would therefore require holistic and comprehensive approaches.

Full Text Available School nutrition policies provide promising avenues towards the improvement of children’s eating habits and the prevention of obesity. Childhood obesity rates and related chronic diseases are increasing in Queensland, in part as a result of unhealthy eating habits and lack of physical activity. There is a very high investment by the Queensland government in maintaining healthy weight and promoting nutrition and physical activity among schoolchildren through delivering a range of initiatives across the state. However, there is a lack of evidence concerning the effectiveness of nutrition/physical education and parental involvement programs addressing obesity delivered in Queensland schools. This paper can be used to guide government and policy-makers regarding the most effective policy options that will promote healthy eating and physical activity among Queensland schoolchildren. The aim of this paper is to: (i summarize current evidence on Queensland government responses to obesity; and (ii discuss potential policy options that could support healthy eating and regular physical activity, and examine the evidence base for each option and suggest new areas for future research.

The Queensland branch of the Royal Australasian College of Physicians (RACP) commissioned this study to update their workforce profile and examine rural practice. The present investigation aimed to describe characteristics of Queensland physicians and determine the influence of childhood and training locations on current rural practice. A cross-sectional online survey, conducted 4 July-4 November 2013, was administered to Fellows of The RACP, Queensland. Descriptive statistics report characteristics and logistic regression analyses identify associations and interactions. The outcome measure was current practice location using the Australian Standard Geographic Classification - Remoteness Area. Data were obtained for 633 physicians. Their average age was 49.5 years, a third was female and a quarter was in rural practice. Rural practice was associated with a rural childhood (odds ratio (OR) (95% confidence interval, CI) 1.89 (1.10, 3.27) P = 0.02) and any time spent as an intern (OR 4.07 (2.12, 7.82) P < 0.001) or registrar (OR 4.00 (2.21, 7.26) P < 0.001) in a rural location. Physicians with a rural childhood and rural training were most likely to be in rural practice. However, those who had a metropolitan childhood and a rural internship were approximately five times more likely to be working in rural practice than physicians with no rural exposure (OR 5.33 (1.61, 17.60) P < 0.01). The findings demonstrate the positive effect of rural vocational training on rural practice. A prospective study would determine if recent changes to the Basic Physician Training Pathway and the Basic Paediatric Training Network (more rural training than previous pathways) increases the rate of rural practice. © 2016 Royal Australasian College of Physicians.

To identify the level of public support for a Human Rights Act for Queensland (HRAQ) and for inclusion of the right to health by participants in a public inquiry process. We reviewed the 492 written submissions to the Legal Affairs and Community Safety Committee's Inquiry into a potential HRAQ and the transcripts documenting the public hearings held by the Committee in 2016. A total of 465 written submissions were analysed; 419 (90%) were for a HRAQ. More than 80% of the 'for' submissions advocated the right to health's inclusion. At the seven public hearings, 72 persons made verbal submissions and most supported a HRAQ. Five major themes were identified in our synthesis of the public hearing transcripts. Three related specifically to health and human rights: 1) the need to consider the holistic health and human rights of Indigenous Queenslanders and Indigenous Queensland communities; 2) instilling a human rights culture in Queensland; and 3) access to health care and the underlying determinants of health. The other two themes related to the conduct of the Inquiry: 4) the importance of community participation in developing a HRAQ; and 5) concerns about the public consultation processes. This study found strong support in the majority of submissions for the Queensland Parliament to draft and enact a HRAQ, and for the inclusion of the right to health in such legislation. Implications for public health: The Queensland Parliament's enactment of a HRAQ that expressly included the right to health would increase the accountability and transparency of government health (and related) decision making and resource allocation, and would better identify and address health inequities across the state. This Act is imperative for improving the health and wellbeing of all Queenslanders, particularly rural and remote and Aboriginal and Torres Strait Islander Queenslanders. © 2017 The Authors.

To explore links between genetic responsiveness to the bitter taste of 6-n-propylthiouracil (PROP) and self-reported preferences for vegetables and fruit of female breast care patients. PROP tasting was defined by detection thresholds and by perceived bitterness and hedonic ratings for PROP solutions. Nontasters, medium tasters, and supertasters were identified by their PROP thresholds and by the ratio of perceived bitterness of PROP to the perceived saltiness of sodium chloride solutions. Subjects rated preferences for vegetables and fruit using 9-point category scales. A clinical sample of 170 patients with newly diagnosed breast cancer and 156 cancer-free control subjects were recruited from the University of Michigan Breast Care Center. Principal components factor analysis, one-way analyses of variance, and Pearson correlations and chi 2 tests were used to analyze taste and food preference data. Genetic responsiveness to PROP was associated with lower acceptance of cruciferous and selected green and raw vegetables (P cancer prevention that emphasize consumption of cruciferous vegetables and bitter salad greens. Alternatively, PROP-sensitive women may seek to reduce bitter taste by adding fat, sugar, or salt.

Truck trap collections of Ceratopogonidae were made over a period of 27 months (November 1973-February 1976) at Tingalpa Creek, in southeast Queensland, Australia. Six collections were made on each of 95 days, giving 570 observations and a total of 29,378 Culicoides. Two collections were made before, one at, and three after sunset. Separate analyses were made of the catches of thirteen entities: male and female C. austropalpalis, C. brevitarsis, C. marksi, C. marmoratus and C. victoriae, female C. henryi and C. longior, and total C. bundyensis. Catches were dominated by C. brevitarsis (35.2%) and C. marmoratus (32.3%) and, with C. victoriae, were taken on almost every collecting day over all seasons. Sex ratios (M:F) varied from 0:100 for C. longior to 130:100 for C. marksi. Collections of all entities, except female C. henryi, were greatest (50-70% of the daily catch) at sunset. In winter there was substantial activity in the hour before sunset. Time of day was the most important variable, accounting for 15-45% of the observed variation. Between-day differences were significant for all except C. austropalpalis, C. victoriae and male C. marksi. Culicoides brevitarsis, C. bundyensis and C. longior had highly significant annual cycles, C. victoriae and female C. austropalpalis had significant lunar cycles, and C. longior had a significant tidal cycle. Logarithms of catches of female C. austropalpalis, C. brevitarsis, C. henryi, C. marmoratus, and female and male C. victoriae were inversely related to linear wind speed. Log catches of female C. austropalpalis, C. brevitarsis, C. marmoratus and C. victoriae, and male C. marksi and C. victoriae were positively related to temperature (quadratic).

Diagnosis of fruit sensitisation by skin prick test (SPT) is fast and easy to perform. Nevertheless, some fruit is not available throughout the year. Freezing aliquots of these fresh fruits to be defrosted would be a good solution to perform SPT at any time. To compare the reproducibility of SPT with Rosaceae and Cucurbitaceae frozen fruit with fresh and commercial fruit extracts. SPT with the following fruit were performed: apricot, cherry, strawberry, nectarine, Japanese medlar, peach, (peel and pulp), yellow and red plum, melon and watermelon. We compared fresh fruit, commercial extract and fruit which had been frozen at -18 degrees C. Results were read by planimetry (Inmunotek prick-film) after 15 minutes. The study group comprised 48 patients (9 males, 39 females) with a mean age of 31, 6 +/- 2.0 years. Concordance of positive and negative results was extremely high and significant in all cases. Correlation between frozen fruit and commercial extract, frozen fruit and fresh and commercial extract and fresh fruit was statistically significant in all cases except for strawberry. The use of frozen fruit is a valid method, as the performance of the SPT is similar to that of fresh fruit. This enables diagnostic procedures with seasonal fruit at any time of the year.

The Central Queensland University (CQU) has championed a self-contained concrete lined evapotranspiration channel. Any non-transpired effluent returns to a holding tank and is recirculated through the evapotranspiration channel until it is used. This paper examines the results from the Rockhampton trial site. Nutrient ions in the effluent were quantified over time and found not to accumulate in solution. Microbial analysis of the treated effluent was performed and was found to be within the ranges required by the relevant legislative codes. Citrus fruit grown in the evapotranspiration channel were sampled and no elevated levels of faecal coliforms were recorded. Macronutrients and micronutrients of the soil in the channels were measured over a 5-year period. No toxic accumulations or nutrient deficiencies in the soil occurred. Levels of salinity and sodicity in the evapotranspiration channel soil were quantified. Salinity rose slightly, as did sodium. Concentrations of salts and sodium did not reach unsustainable levels. The aim of the trial was to develop an on-site treatment and reuse system that is sustainable and protects public and environmental health.

Queensland, Australia. Understanding paediatric tuberculosis (TB) is important, as children with TB typically reflect recent community transmission. Children pose unique diagnostic challenges and are at risk of developing severe disseminated infection. To describe the epidemiology, presentation and outcomes of children with TB disease in Queensland. This is a retrospective case series of children diagnosed with TB aged 0-16 years notified in 2005-2014. Data collected in the Queensland Notifiable Conditions System were extracted and analysed. Of 127 children diagnosed with TB, 16 were Australian-born (including 12 Indigenous Queenslanders), 41 were overseas-born permanent and temporary residents and 70 were cross-border Papua New Guinea (PNG) children; 88 children had pulmonary disease (with/without other sites) and 39 had extra-pulmonary disease only, with lymph node TB the predominant extra-pulmonary site; 70.1% of children had laboratory confirmation; and 14 cross-border children had multidrug-resistant TB. Treatment outcomes among children residing in Australia were good (100% among Australian-born and 97.2% among permanent and temporary residents), but they were less favourable among PNG children diagnosed in the Torres Strait Protected Zone (76.6%). Queensland has unique challenges in TB control, with a high proportion of cross-border diagnoses and over-representation of Indigenous children. Vigilance is needed given the wide spectrum of clinical presentation, particularly in high-risk communities.

Salmonella enterica is a major cause of gastroenteritis and foodborne illness in Australia where notification rates in the state of Queensland are the highest in the country. S. Enteritidis is among the five most common serotypes reported in Queensland and it is a priority for epidemiological surveillance due to concerns regarding its emergence in Australia. Using whole genome sequencing, we have analysed the genomic epidemiology of 217 S. Enteritidis isolates from Queensland, and observed that they fall into three distinct clades, which we have differentiated as Clades A, B and C. Phage types and MLST sequence types differed between the clades and comparative genomic analysis has shown that each has a unique profile of prophage and genomic islands. Several of the phage regions present in the S. Enteritidis reference strain P125109 were absent in Clades A and C, and these clades also had difference in the presence of pathogenicity islands, containing complete SPI-6 and SPI-19 regions, while P125109 does not. Antimicrobial resistance markers were found in 39 isolates, all but one of which belonged to Clade B. Phylogenetic analysis of the Queensland isolates in the context of 170 international strains showed that Queensland Clade B isolates group together with the previously identified global clade, while the other two clades are distinct and appear largely restricted to Australia. Locally sourced environmental isolates included in this analysis all belonged to Clades A and C, which is consistent with the theory that these clades are a source of locally acquired infection, while Clade B isolates are mostly travel related.

Males and females gain differentially from sociality in a promiscuous fruit bat Cynopterus sphinx.

Full Text Available Sociality emerges when the benefits of group living outweigh its costs. While both males and females are capable of strong social ties, the evolutionary drivers for sociality and the benefits accrued maybe different for each sex. In this study, we investigate the differential reproductive success benefits of group membership that males and females might obtain in the promiscuous fruit bat Cynopterus sphinx. Individuals of this species live in flexible social groups called colonies. These colonies are labile and there is high turnover of individuals. However, colony males sire more offspring within the colony suggesting that being part of a colony may result in reproductive benefits for males. This also raises the possibility that long-term loyalty towards the colony may confer additional advantage in terms of higher reproductive success. We used ten seasons of genetic parentage data to estimate reproductive success and relatedness of individuals in the colony. We used recapture data to identify long and short-term residents in the colony as well as to obtain rates of recapture for males and females. Our results reveal that males have a significantly higher chance of becoming long-term residents (than females, and these long-term resident males gain twice the reproductive success compared to short-term resident males. We also observed that long-term resident females are related to each other and also achieve higher reproductive success than short-term resident females. In contrast, long-term resident males do not differ from short-term resident males in their levels of relatedness. Our results re-iterate the benefits of sociality even in species that are promiscuous and socially labile and possible benefits of maintaining a colony.

ABLV is widely distributed in Australian bats, and any bite or scratch from an Australian bat is considered a potential exposure to ABLV.Potential exposure to ABLV has been a notifiable condition in Queensland since 2005. We analysed notification data for potential exposures occurring between 2009 and 2014. There were 1,515 potential exposures to ABLV notified in Queensland, with an average annual notification rate of 5.6 per 100,000 population per year. The majority of notified individuals (96% were potentially exposed to ABLV via bats, with a small number of cases potentially exposed via two ABLV infected horses and an ABLV infected human. The most common routes of potential exposure were through bat scratches (47% or bites (37%, with less common routes being mucous membrane/broken skin exposure to bat saliva/brain tissue (2.2%. Intentional handling of bats by the general public was the major cause of potential exposures (56% of notifications.

For regional and rural Queenslanders, chronic viral hepatitis treatment is a major unmet health need, with restricted access to specialists outside of tertiary, largely metropolitan hospitals. To increase treatment of chronic viral hepatitis in regional Queensland, a team-based telehealth model was expanded. This expansion embedded an initial nursing consultation prior to specialist telehealth consultation. We conducted a retrospective audit of the introduction and expansion of hepatology telehealth services. Activity from July 2014-June 2015 (pre-expansion) was compared with July 2015- June 2016 (post-expansion). Interviews were conducted with key staff to determine factors contributing to success of the service and identify ongoing challenges to the service model. A greater than four-fold increase in clinical consultation was observed (131 telehealth consultations pre-expansion vs 572 post-expansion; p Queensland. It may serve as a model to further expand telehealth management of chronic disease for regional Queenslanders. © The Author(s) 2016.

Background Barmah Forest virus (BFV) disease is a common and wide-spread mosquito-borne disease in Australia. This study investigated the spatio-temporal patterns of BFV disease in Queensland, Australia using geographical information system (GIS) tools and geostatistical analysis. Methods/Principal Findings We calculated the incidence rates and standardised incidence rates of BFV disease. Moran's I statistic was used to assess the spatial autocorrelation of BFV incidences. Spatial dynamics of BFV disease was examined using semi-variogram analysis. Interpolation techniques were applied to visualise and display the spatial distribution of BFV disease in statistical local areas (SLAs) throughout Queensland. Mapping of BFV disease by SLAs reveals the presence of substantial spatio-temporal variation over time. Statistically significant differences in BFV incidence rates were identified among age groups (χ2 = 7587, df = 7327,pQueensland using GIS and geostatistics. The BFV transmission varied with age and gender, which may be due to exposure rates or behavioural risk factors. There are differences in the spatio-temporal patterns of BFV disease which may be related to local socio-ecological and environmental factors. These research findings may have implications in the BFV disease control and prevention programs in Queensland. PMID:22022430

In response to concerns about the health consequences of high-risk drinking by young people, the Australian Government increased the tax on pre-mixed alcoholic beverages ('alcopops') favoured by this demographic. We measured changes in admissions for alcohol-related harm to health throughout Queensland, before and after the tax increase in April 2008. We used data from the Queensland Trauma Register, Hospitals Admitted Patients Data Collection, and the Emergency Department Information System to calculate alcohol-related admission rates per 100,000 people, for 15 - 29 year-olds. We analysed data over 3 years (April 2006 - April 2009), using interrupted time-series analyses. This covered 2 years before, and 1 year after, the tax increase. We investigated both mental and behavioural consequences (via F10 codes), and intentional/unintentional injuries (S and T codes). We fitted an auto-regressive integrated moving average (ARIMA) model, to test for any changes following the increased tax. There was no decrease in alcohol-related admissions in 15 - 29 year-olds. We found similar results for males and females, as well as definitions of alcohol-related harms that were narrow (F10 codes only) and broad (F10, S and T codes). The increased tax on 'alcopops' was not associated with any reduction in hospital admissions for alcohol-related harms in Queensland 15 - 29 year-olds.

Haldar, Chandana; Yadav, Rajesh; Alipreeta

2006-08-01

We studied the annual correlation of ovarian activity and pineal gland in relation with seasonal variation and gestation of a tropical zone short-nosed fruit bat Cynopterus sphinx. Female bats showed bimodal polyestry (February/March and September/October) in their reproductive cycle. Plasma estradiol concentration ran parallel with ovarian activity and had an inverse relation with pineal mass and peripheral melatonin concentration. Due to the delayed embryonic development in the uterus (October-March) of female bats, interestingly, the uterine activity did not show a parallel relation with ovarian activity and estradiol level. Further, compared with normal non-pregnant females, melatonin level was high during gestation and delayed embryonic development phase. This suggests that the reproductive synchrony and annual variation in ovarian activity of this nocturnal flying mammal differ from other common tropical mammals. The delayed embryonic development in bats might be an adaptive strategy for the unfavorable conditions of the seasons and might be regulated by high peripheral estradiol and melatonin concentration.

This study investigated alternative in-field chemical controls against Bactrocera tryoni (Froggatt). Bioassay 1 tested the mortality of adults exposed to fruit and filter paper dipped in insecticide, and the topical application of insecticide to adults/fruit. Bioassay 2 measured the mortality of adults permitted to oviposit on fruit dipped in insecticide and aged 0, 1, 3, or 5 days, plus the production of offspring. Bioassay 3 tested infested fruit sprayed with insecticide. The field bioassay trialed the mortality of adults exposed to one- and five-day insecticide residues on peaches, and subsequent offspring. Abamectin, alpha-cypermethrin, clothianidin, dimethoate (half-label rate), emamectin benzoate, fenthion (half- and full-label rate), and trichlorfon were the most efficacious in bioassay 1, across 18 tested insecticide treatments. Overall, the LT50 value was lowest for fenthion (full-label rate), clothianidin, and alpha-cypermethrin. Fenthion, emamectin benzoate, and abamectin had the greatest effect on adult mortality and offspring production. Infested fruit treated with acetamiprid, fenthion, and thiacloprid produced no/very few offspring. Alpha-cypermethrin demonstrated good field efficacy against adults (one day post treatment: 97.2% mortality, five day post treatment: 98.8% mortality) and subsequent offspring (100% across one and five day post treatments), comparable to that of fenthion (full-label rate) (100% mortality for offspring and adults across both post treatments). Alpha-cypermethrin is a possible alternative to fenthion against B. tryoni; as a pyrethroid, it may not be desirable if adjunct biological control is imperative. Thiacloprid and Acetamiprid may be useful as a post-harvest treatment. PMID:28486404

Navi, Maryam; Skelly, Chris; Taulis, Mauricio; Nasiri, Shahram

2015-01-01

The extraction of coal seam gas (CSG) produces large volumes of potentially contaminated water. It has raised concerns about the environmental health impacts of the co-produced CSG water. In this paper, we review CSG water contaminants and their potential health effects in the context of exposure pathways in Queensland's CSG basins. The hazardous substances associated with CSG water in Queensland include fluoride, boron, lead and benzene. The exposure pathways for CSG water are (1) water used for municipal purposes; (2) recreational water activities in rivers; (3) occupational exposures; (4) water extracted from contaminated aquifers; and (5) indirect exposure through the food chain. We recommend mapping of exposure pathways into communities in CSG regions to determine the potentially exposed populations in Queensland. Future efforts to monitor chemicals of concern and consolidate them into a central database will build the necessary capability to undertake a much needed environmental health impact assessment.

2017-09-01

Full Text Available Objectives This article aimed to compare alcohol consumption between the populations of Queensland in Australia and Alberta in Canada. Furthermore, the associations between greater alcohol consumption and socio-demographic characteristics were explored in each population. Methods Data from 2500 participants of the 2013 Alberta Survey and the 2013 Queensland Social Survey were analyzed. Regression analyses were used to explore the associations between alcohol risk and socio-demographic characteristics. Results A higher rate of hazardous alcohol use was found in Queenslanders than in Albertans. In both Albertans and Queenslanders, hazardous alcohol use was associated with being between 18 and 24 years of age. Higher income, having no religion, living alone, and being born in Canada were also associated with alcohol risk in Albertans; while in Queenslanders, hazardous alcohol use was also associated with common-law marital status. In addition, hazardous alcohol use was lower among respondents with a non-Catholic or Protestant religious affiliation. Conclusions Younger age was associated with greater hazardous alcohol use in both populations. In addition, different socio-demographic factors were associated with hazardous alcohol use in each of the populations studied. Our results allowed us to identify the socio-demographic profiles associated with hazardous alcohol use in Alberta and Queensland. These profiles constitute valuable sources of information for local health authorities and policymakers when designing suitable preventive strategies targeting hazardous alcohol use. Overall, the present study highlights the importance of analyzing the socio-demographic factors associated with alcohol consumption in population-specific contexts.

Full Text Available Abstract Background There has been a lack of investigation into the spatial distribution and clustering of suicide in Australia, where the population density is lower than many countries and varies dramatically among urban, rural and remote areas. This study aims to examine the spatial distribution of suicide at a Local Governmental Area (LGA level and identify the LGAs with a high relative risk of suicide in Queensland, Australia, using geographical information system (GIS techniques. Methods Data on suicide and demographic variables in each LGA between 1999 and 2003 were acquired from the Australian Bureau of Statistics. An age standardised mortality (ASM rate for suicide was calculated at the LGA level. GIS techniques were used to examine the geographical difference of suicide across different areas. Results Far north and north-eastern Queensland (i.e., Cook and Mornington Shires had the highest suicide incidence in both genders, while the south-western areas (i.e., Barcoo and Bauhinia Shires had the lowest incidence in both genders. In different age groups (≤24 years, 25 to 44 years, 45 to 64 years, and ≥65 years, ASM rates of suicide varied with gender at the LGA level. Mornington and six other LGAs with low socioeconomic status in the upper Southeast had significant spatial clusters of high suicide risk. Conclusions There was a notable difference in ASM rates of suicide at the LGA level in Queensland. Some LGAs had significant spatial clusters of high suicide risk. The determinants of the geographical difference of suicide should be addressed in future research.

To use the north Queensland banana industry as a case study to examine the extent to which cosmetic standards set by retailers influence the amount of edible waste generated on-farm and the effect of this on the sustainability of the Australian food and nutrition system. Waste audits were performed on-farm at a banana packing shed to quantify the amount of fruit discarded due to cosmetic imperfections. These data, together with production records provided by the Department of Primary Industries and Fisheries and interviews with growers, were used to inform a nutritional analysis, a life cycle assessment and an economic analysis to quantify nutritional, environmental and economic impacts. North Queensland, Australia Banana farms and packing shed.ResultBetween 10 and 30 % of the north Queensland banana crop is discarded on-farm. Of this, 78 % was found to be due to cosmetic imperfections, which equates to an industry total of 37 000 tonnes per annum. This waste represents a loss of 137 billion kilojoules with accompanying macro- and micronutrients. The life cycle assessment indicated that approximately 16 300 tonnes of carbon dioxide emissions, 11·2 gigalitres of virtual water as well as other natural resources are embodied in the waste. There is an industry-wide, economic loss of approximately $AU 26·9 million per annum. The majority of on-farm banana waste is caused by arbitrary cosmetic standards set by retailers, resulting in significant nutritional, environmental and economic losses. Public health nutritionists have a role to play across the entire food chain to minimize the impacts of waste on the food system.

1990-01-01

The volume of pollen, total number of pollen/flower, the percent of pollen germination and tube growth of long-styled flower were higher than the short-styled flowers in S. torvum. In addition, the pollination studies were conducted among the four selected sets for optimum fruit set investigation. Fruit set was not seen in both the first and second sets (female shorts-short male and female short-long male). However, the maximum fruit set was obtained in the fourth set (female long-male long). Pollen grains of long-styled flowers irradiated with 1-800 krad were germinated in the basal medium. The percent of pollen germination and the tube growth was stimulated over the control with 1 and 50 krad dose exposures, but increasing dose rates inhibited both the above processes. Utilization of insoluble polysaccharides, and the synthesis of RNA and protein were enhanced over the control with the effect of 50 krad. The higher (800 krad) dose exposures inhibited all the above cytochemical constituents. Various dose-treated pollens were used to pollinate the stigma surface of the long-styled flowers. The fruit set, fruit volume, fresh and dry weight of fruits, and the number of seed set/fruit, were enhanced over the control by 1 and 50 krad, while the higher doses caused inhibitory effect. Interestingly, the fruit set was not caused by radiation doses 400 krad and above. (author)

To identify the spatio-temporal patterns and environmental factors associated with Clostridium difficile infection (CDI) in Queensland, Australia. Data from patients tested for CDI were collected from 392 postcodes across Queensland between May 2003 and December 2012. A binomial logistic regression model, with CDI status as the outcome, was built in a Bayesian framework, incorporating fixed effects for sex, age, source of the sample (healthcare facility or community), elevation, rainfall, land surface temperature, seasons of the year, time in months and spatially unstructured random effects at the postcode level. C. difficile was identified in 13.1% of the samples, the proportion significantly increased over the study period from 5.9% in 2003 to 18.8% in 2012. CDI peaked in summer (14.6%) and was at its lowest in autumn (10.1%). Other factors significantly associated with CDI included female sex (OR: 1.08; 95%CI: 1.01-1.14), community source samples (OR: 1.12; 95%CI: 1.05-1.20), and higher rainfall (OR: 1.09; 95%CI: 1.02-1.17). There was no significant spatial variation in CDI after accounting for the fixed effects in the model. There was an increasing annual trend in CDI in Queensland from 2003 to 2012. Peaks of CDI were found in summer (December-February), which is at odds with the current epidemiological pattern described for northern hemisphere countries. Epidemiologically plausible explanations for this disparity require further investigation. Copyright © 2014 The British Infection Association. Published by Elsevier Ltd. All rights reserved.

To assess the current frequency of sunburn, a preventable risk factor for skin cancer, among Queensland adults. Cross-sectional population-based surveys of 16 473 residents aged ≥ 18 2013s across Queensland in 2009 and 2010. Proportion of the adult population reporting sunburn (skin reddening lasting 12 hours or more) during the previous weekend, by age, sex and other risk factors. One in eight men and one in 12 women in Queensland reported being sunburnt on the previous weekend. Age up to 65 2013s was the strongest predictor of sunburn: eg, people aged 18-24 2013s were seven times more likely (adjusted odds ratio [OR], 7.35; 95% CI, 5.09-10.62) and those aged 35-44 2013s were five times more likely (adjusted OR, 5.22) to report sunburn compared with those aged ≥ 65 2013s. Not having a tertiary education and being in the workforce were also significantly associated with sunburn. Those who had undertaken any physical activity the previous week were more likely to be sunburnt than those who were physically inactive. Sunburn was significantly less likely among people who generally took sun-protective measures in summer. Sunburn was not related to location of residence, socioeconomic disadvantage, skin colour, body weight or current smoking status. Sunburn remains a public health problem among Queensland residents, especially those under 45 2013s of age. Sun-safe habits reduce sunburn risk, but advice must be integrated with health promotion messages regarding physical activity to reduce the skin cancer burden while maintaining active wellbeing.

To derive planning estimates for the provision of public mental health services in Queensland 2007-2017. We used a five-step approach that involved: (i) estimating the prevalence and severity of mental disorders in Queensland, and the number of people at each level of severity treated by health services; (ii) benchmarking the level and mix of specialised mental health services in Queensland against national data; (iii) examining 5-year trends in Queensland public sector mental health service utilisation; (iv) reviewing Australian and international planning benchmarks; and (v) setting resource targets based on the results of the preceding four steps. Best available evidence was used where possible, supplemented by value judgements as required. Recommended resource targets for inpatient service were: 20 acute beds per 100,000 population, consistent with national average service provision but 13% above Queensland provision in 2005; and 10 non-acute beds per 100,000, 65% below Queensland levels in 2005. Growth in service provision was recommended for all other components. Adult residential rehabilitation service targets were 10 clinical 24-hour staffed beds per 100,000, and 18 non-clinical beds per 100,000. Supported accommodation targets were 35 beds per 100,000 in supervised hostels and 35 places per 100,000 in supported public housing. A direct care clinical workforce of 70 FTE per 100,000 for ambulatory care services was recommended. Fifteen per cent of total mental health funding was recommended for community support services provided by non-government organisations. The recommended targets pointed to specific areas for priority in Queensland, notably the need for additional acute inpatient services for older persons and expansion of clinical ambulatory care, residential rehabilitation and supported accommodation services. The development of nationally agreed planning targets for public mental health services and the mental health community support sector were

To determine the rabies vaccination status of Queensland veterinarians and veterinary students and their perception of zoonotic risk from Australian bat lyssavirus (ABLV). Cross-sectional questionnaire surveys. Questionnaires were sent by post in 2011 to veterinary surgeons registered in Queensland, to final-year veterinary students at James Cook University via SurveyMonkey® in 2013 and to final-year veterinary students at James Cook University and University of Queensland via SurveyMonkey® in 2014. The response rate for registered veterinarians was 33.5% and for veterinary students 33.3% and 30% in 2013 and 2014, respectively. Of the 466 registered veterinary surgeons, 147 (31.5%) had been vaccinated, with 72 (15.5%) currently vaccinated. For veterinary students the rabies vaccination rate was 20.0% (4/20) and 13.0% (6/46) in the 2013 and 2014 surveys, respectively. More than 95% of veterinary students had received the mandatory Q fever vaccine. Both veterinarians and students regarded bats and horses as high-risk species for zoonoses. Queensland veterinarians and veterinary students have low levels of protection against ABLV. Although incidents of ABLV spilling over from a bat to a domestic mammal are likely to remain rare, they pose a significant human health and occupational risk given the outcome of infection in humans is high consequence. Principals of veterinary practices and veterinary authorities in Australia should implement a policy of rabies vaccination for clinical staff and veterinary students. © 2018 Australian Veterinary Association.

Merkel cell carcinoma (MCC) is an uncommon but highly invasive form of skin cancer. The mechanisms that cause MCC are yet to be fully determined. To compare the incidence and survival rates of MCC in Queensland, Australia, known to be a high-risk area, with MCC incidence and survival elsewhere in the world. We also analyzed incidence trends and differences in survival by key demographic and clinical characteristics. Retrospective cohort study of population-based administrative data for MCC collected by the Queensland Cancer Registry and supplemented with detailed histopathologic data. Deidentified records were obtained of all Queensland residents diagnosed as having MCC during the period from 1993 to 2010. A subsample of histopathologic records were reviewed by a senior dermatopathologist to determine the potential for misclassification. A total of 879 eligible cases of MCC were included in the study. Incidence rates were directly age standardized to the 2000 United States Standard Population. Trends were examined using Joinpoint software with results expressed in terms of the annual percentage change. The period method was used to calculate 5-year relative survival, and adjusted hazard ratios were obtained from multivariate Poisson models. There were 340 cases of MCC diagnosed in Queensland between 2006 and 2010, corresponding to an incidence rate of 1.6 per 100,000 population. Men (2.5 per 100,000) had higher incidence than women (0.9 per 100,000), and rates peaked at 20.7 per 100,000 for persons 80 years or older. The overall incidence of MCC increased by an average of 2.6% per year from 1993 onwards. Relative survival was 41% after 5 years, with significantly better survival found for those younger than 70 years at diagnosis (56%-60%), those with tumors on the face or ears (51%), and those with stage I lesions (49%). Incidence rates for MCC in Queensland are at least double those of any that have been previously published elsewhere in the world. It is likely

The paper also reviewed the major flooding and cyclone events that occurred in the last six years in Queensland. Generally, a rapid increase in deterioration of the structural and surface conditions such as roughness and rutting was observed in pavements after the flood as a result of the inundation. An increasing need for road rehabilitation was also observed after the recent flooding events from 2010 to 2015 in Queensland. Assessing the rapid deterioration of the structural and surface condition of the flood affected pavements is a prerequisite for the accurate prediction of pavement performance, a better decision making process and the management of these roads. Although this paper did not include any model for roughness and rutting, deterioration models for roughness and rutting of flood affected pavements are currently being developed as a part of the future scope of this research.

Australian rainforests have been fragmented due to past climatic changes and more recently landscape change as a result of clearing for agriculture and urban spread. The subtropical rainforests of South Eastern Queensland are significantly more fragmented than the tropical World Heritage listed northern rainforests and are subject to much greater human population pressures. The Australian rainforest flora is relatively taxonomically rich at the family level, but less so at the species level. Current methods to assess biodiversity based on species numbers fail to adequately capture this richness at higher taxonomic levels. We developed a DNA barcode library for the SE Queensland rainforest flora to support a methodology for biodiversity assessment that incorporates both taxonomic diversity and phylogenetic relationships. We placed our SE Queensland phylogeny based on a three marker DNA barcode within a larger international rainforest barcode library and used this to calculate phylogenetic diversity (PD). We compared phylo- diversity measures, species composition and richness and ecosystem diversity of the SE Queensland rainforest estate to identify which bio subregions contain the greatest rainforest biodiversity, subregion relationships and their level of protection. We identified areas of highest conservation priority. Diversity was not correlated with rainforest area in SE Queensland subregions but PD was correlated with both the percent of the subregion occupied by rainforest and the diversity of regional ecosystems (RE) present. The patterns of species diversity and phylogenetic diversity suggest a strong influence of historical biogeography. Some subregions contain significantly more PD than expected by chance, consistent with the concept of refugia, while others were significantly phylogenetically clustered, consistent with recent range expansions.

To determine the impact of the introduction of universal access to ambulance services via the implementation of the Community Ambulance Cover (CAC) program in Queensland in 2003-04. The study involved a 10-year (2000-01 to 2009-10) retrospective analysis of routinely collected data reported by the Queensland Ambulance Service (QAS) and by the Council of Ambulance Authorities. The data were analysed for the impact of policy changes that resulted in universal access to ambulance services in Queensland. QAS is a statewide, publically funded ambulance service. In Queensland, ambulance utilisation rate (AUR) per 1000 persons grew by 41% over the decade or 3.9% per annum (10-year mean=149.8, 95% CI: 137.3-162.3). The AUR mean after CAC was significantly higher for urgent incidents than for non-urgent ones. However projection modelling demonstrates that URs after the introduction of CAC were significantly lower than the projected utilisation for the same period. The introduction of universal access under the Community Ambulance Cover program in Queensland has not had any significant independent long-term impact on demand overall. There has been a reduction in the long-term growth rate, which may have been contributed to by an 'appropriate use' public awareness program.

2010-04-01

The aim of this study was to investigate factors influencing career choices in radiology trainees. We distributed a 27-question written survey to all radiology registrars in Queensland. The questions investigated whether radiology was their first specialty choice, career satisfaction, ideal working conditions and attitudes regarding having children during the time of training. Forty-four of 51 surveys were returned (86% participation rate, 73% men, P = 0.048055) with 100% reporting a high job satisfaction; 28% of male registrars compared to 8% of female registrars did extra work outside of training to earn extra money (P = 0.000003), and 17% of female registrars took a leave of absence during their training, while no male registrar did (P = 0.087923). Only one female trainee worked part-time (P = 0.272727). In addition, 58% of female registrars planned a pregnancy (P = 0.731789) before completion of training; 83% of women versus 75% of men had no children (P = 0.329263). Only 5% of trainees agreed that it was easy to arrange part-time training, only 14% stated that it was easy to negotiate flexible work schedules and 7% agreed that it was easy to return to work after a period of absence. 'Time spent with immediate family' was rated the most important lifestyle factor, followed by 'work hours' and 'on-call duty'. The least important factors were 'being away from extended family', 'availability of part-time work' and whether 'work was in a rural location'. Overall job satisfaction is high among radiology trainees. Nevertheless, lifestyle factors, particularly those related to work time, are becoming more important for career decisions. This should be taken into account when designing and structuring radiology training to ensure that it is considered an attractive career choice.

2006-09-01

The aim of this study was to assess the awareness of, and attitudes to, mental health issues in rural dwelling Queensland residents. A secondary objective was to provide baseline data of mental health literacy prior to the implementation of Australian Integrated Mental Health Initiative--a health promotion strategy aimed at improving the health outcomes of people with chronic or recurring mental disorders. In 2004 a random sample of 2% (2132) of the estimated adult population in each of eight towns in rural Queensland was sent a postal survey and invited to participate in the project. A series of questions were asked based on a vignette describing a person suffering major depression. In addition, questions assessed respondents' awareness and perceptions of community mental health agencies. Approximately one-third (36%) of those surveyed completed and returned the questionnaire. While a higher proportion of respondents (81%) correctly identified and labelled the problem in the vignette as depression than previously reported in Australian community surveys, the majority of respondents (66%) underestimated the prevalence of mental health problems in the community. Furthermore, a substantial number of respondents (37%) were unaware of agencies in their community to assist people with mental health issues while a majority of respondents (57.6%) considered that the services offered by those agencies were poor. While mental health literacy in rural Queensland appears to be comparable to other Australian regions, several gaps in knowledge were identified. This is in spite of recent widespread coverage of depression in the media and thus, there is a continuing need for mental health education in rural Queensland.

The koala (Phascolarctos cinereus) suffered population declines and local extirpation due to hunting in the early 20th century, especially in southern Australia. Koalas were subsequently reintroduced to the Brisbane Ranges (BR) and Stony Rises (SR) by translocating individuals from a population on French Island descended from a small number of founders. To examine genetic diversity and north-south differentiation, we genotyped 13 microsatellite markers in 46 wild koalas from the BR and SR, and 27 Queensland koalas kept at the US zoos. The Queensland koalas displayed much higher heterozygosity (H O = 0.73) than the 2 southern Australian koala populations examined: H O = 0.49 in the BR, whereas H O = 0.41 in the SR. This is consistent with the historical accounts of bottlenecks and founder events affecting the southern populations and contrasts with reports of high genetic diversity in some southern populations. The 2 southern Australian koala populations were genetically similar (F ST = 0.018, P = 0.052). By contrast, northern and southern Australian koalas were highly differentiated (F ST = 0.27, P < 0.001), thereby suggesting that geographic structuring should be considered in the conservation management of koalas. Sequencing of 648bp of the mtDNA control region in Queensland koalas found 8 distinct haplotypes, one of which had not been previously detected among koalas. Queensland koalas displayed high mitochondrial haplotype diversity (H = 0.753) and nucleotide diversity (π = 0.0072), indicating along with the microsatellite data that North American zoos have maintained high levels of genetic diversity among their Queensland koalas. © The American Genetic Association 2016.

The Health Legislation Amendment Act 2013 (QLD) and Queensland's health assets privatisation dispute.

Science.gov (United States)

Colton, Caroline; Faunce, Thomas

2014-09-01

'New legislation in Queensland has provided a "pathway" for the privatisation of health assets and services in Queensland, which effectively realigns the health care system to the financial market. This column explores how this legislation contained the antecedents of the Queensland doctors' dispute when doctors roundly rejected new employment contracts in February 2014. It also argues that such legislation and its attendant backlash provides a valuable case study in view of the federal government's 2014 budget offer to the States of extra funding if they sell their health assets to fund new infrastructure. The move to privatise health in Queensland has also resulted in a government assault on the ethical credibility of the opposing medical profession and changes to the health complaints system with the introduction of a Health Ombudsman under ministerial control. The column examines these changes in light of R (Heather) v Leonard Cheshire Foundation [2001] EWHC Admin 429, a case concerning the obligations of a private entity towards publically funded clients in the United Kingdom. In discussing concerns about the impact of privatisation on the medical profession, the column points to a stark conflict between the duty to operate hospitals as a business rather than as a duty to patients.

Objective To determine trends in the incidence of foot-related hospitalisation and amputation amongst persons with diabetes in Queensland (Australia) between 2005 and 2010 that coincided with changes in state-wide ambulatory diabetic foot-related complication management. Methods All data from cases admitted for the principal reason of diabetes foot-related hospitalisation or amputation in Queensland from 2005–2010 were obtained from the Queensland Hospital Admitted Patient Data Collection dataset. Incidence rates for foot-related hospitalisation (admissions, bed days used) and amputation (total, minor, major) cases amongst persons with diabetes were calculated per 1,000 person-years with diabetes (diabetes population) and per 100,000 person-years (general population). Age-sex standardised incidence and age-sex adjusted Poisson regression models were also calculated for the general population. Results There were 4,443 amputations, 24,917 hospital admissions and 260,085 bed days used for diabetes foot-related complications in Queensland. Incidence per 1,000 person-years with diabetes decreased from 2005 to 2010: 43.0% for hospital admissions (36.6 to 20.9), 40.1% bed days (391 to 234), 40.0% total amputations (6.47 to 3.88), 45.0% major amputations (2.18 to 1.20), 37.5% minor amputations (4.29 to 2.68) (p Queensland over a recent six-year period.

This paper reports the findings of a survey undertaken in Queensland, Australia in October 2001. The participants were registered and enrolled nurses and assistants in nursing who were members of the industrial body - the Queensland Nursing Union (QNU), and who were in paid employment in nursing in Queensland. Participants were selected by random sampling from each of the three major employment groups - the aged care, public and private acute sectors. Of the 2800 invited participants, 1477 responded resulting in an overall response rate of 53%. The findings indicate that over 50% of nurses in the aged-care sector, 32% of nurses in the public and 30% of nurses in the private acute sector experience difficulties in meeting patient needs because of insufficient staffing levels. The nurses in this study also believed that there was poor skills-mix, mostly caused by lack of funding, too few experienced staff or too many inexperienced staff. Many nurses in this study expressed their anger and frustration about their inability to complete their work to their professional satisfaction in the paid time available. Further, many nurses also expressed the view that because of this inability they were planning to leave the nursing profession. These findings are consistent with other research into the nursing workforce both within Australia and internationally.

Full Text Available Governments and other policy makers are concerned with the gap in home Internet usage between people from metropolitan and rural areas. A survey conducted in Central Queensland, Australia examined differences in home Internet usage patterns between young and old, male and female, people in urban and rural areas, married and unmarried, well-educated and less educated, rich and poor, and employed and unemployed and found significant differences. These results highlight areas for further research and provide a basis for government agencies and industries to consider these associations in future policy formulation for regional development using ICT. The research suggested that further research should be conducted to monitor consuming behaviors of the youngest age group in Internet use for entertainment and information search in order to detect possible Internet overuse or addiction. In addition, further research should be conducted to find out what people search for on the Internet, and if for employment opportunities, financial incentives are suggested for the unemployed people.

Although home visiting in the early post partum period appears to have increased, there are limited data defining which women receive a visit and none that include Queensland. We aimed to investigate patterns of post partum home visiting in the public and private sectors in Queensland. Data were collected via a retrospective cross-sectional survey of women birthing in Queensland between 1 February and 31 May 2010 at 4 months post partum (n = 6948). Logistic regression was used to assess associations between receiving a home visit and sociodemographic, clinical and hospital variables. Analyses were stratified by public and private birthing sector because of significant differences between sectors. Public sector women were more likely to receive a visit from a nurse or midwife (from the hospital or child health sector) within 10 days of hospital discharge (67.2%) than private sector women (7.2%). Length of hospital stay was associated with home visiting in both sectors. Some vulnerable subpopulations in both sectors were more likely to be visited, whereas others were not. Home visiting in Queensland varies markedly between the public and private sector and is less common in some vulnerable populations. Further consideration to improving the equity of community post partum care in Queensland is needed.

Mosquito-borne diseases are climate sensitive and there has been increasing concern over the impact of climate change on future disease risk. This paper projected the potential future risk of Barmah Forest virus (BFV) disease under climate change scenarios in Queensland, Australia. We obtained data on notified BFV cases, climate (maximum and minimum temperature and rainfall), socio-economic and tidal conditions for current period 2000-2008 for coastal regions in Queensland. Grid-data on future climate projections for 2025, 2050 and 2100 were also obtained. Logistic regression models were built to forecast the otential risk of BFV disease distribution under existing climatic, socio-economic and tidal conditions. The model was applied to estimate the potential geographic distribution of BFV outbreaks under climate change scenarios. The predictive model had good model accuracy, sensitivity and specificity. Maps on potential risk of future BFV disease indicated that disease would vary significantly across coastal regions in Queensland by 2100 due to marked differences in future rainfall and temperature projections. We conclude that the results of this study demonstrate that the future risk of BFV disease would vary across coastal regions in Queensland. These results may be helpful for public health decision making towards developing effective risk management strategies for BFV disease control and prevention programs in Queensland.

We have identified a kind of parthenocarpy in zucchini squash which is associated with an incomplete andromonoecy, i.e. a partial conversion of female into bisexual flowers. Given that andromonoecy in this and other cucurbit species is caused by a reduction of ethylene production in the female flower, the associated parthenocarpic development of the fruit suggested the involvement of ethylene in fruit set and early fruit development. We have compared the production of ethylene as well as the expression of 13 ethylene biosynthesis and signalling genes in pollinated and unpollinated ovaries/fruits of two cultivars, one of which is parthenocarpic (Cavili), while the other is non-parthenocarpic (Tosca). In the latter, unpollinated ovaries show an induction of ethylene biosynthesis and ethylene signal transduction pathway genes three days after anthesis, which is concomitant with the initiation of fruit abortion and senescence. Fruit set and early fruit development in pollinated flowers of both cultivars and unpollinated flowers of Cavili is coupled with low ethylene biosynthesis and signalling, which would also explain the partial andromonoecy in the parthenocarpic genotype. The reduction of ethylene production in the ovary cosegregates with parthenocarpy and partial andromonoecy in the selfing progeny of Cavili. Moreover, the induction of ethylene in anthesis (by ethephon treatments) reduced the percentage of bisexual parthenocarpic flowers in Cavili, while the inhibition of ethylene biosynthesis or response (by AVG and STS treatments) induces not only andromonoecy but also the parthenocarpic development of the fruit in both cultivars. Results demonstrate that a reduction of ethylene production or signalling in the zucchini flower is able to induce fruit set and early fruit development, and therefore that ethylene is actively involved in fruit set and early fruit development.

In this study, we investigated the influence of cultivar type, fruit ripeness, and damage by conspecific larvae on the attraction of Anastrepha obliqua (Macquart) (Diptera: Tephritidae) to and oviposition on carambola fruit (Averroha carambola L.). The attraction of both sexes of A. obliqua to fruit of different quality was evaluated through cage experiments in the field, and the oviposition preferences of mated females were examined in laboratory tests. Both sexes, mated or virgin, were more attracted to the "Maha" fruit than to the "Golden Star" fruit, and the females oviposited more frequently on the Maha cultivar than the Golden Star cultivar. Both sexes were more attracted to ripe and half-ripe Maha fruits than to mature green fruit, and although females did not show a preference for ovipositing on half-ripe or ripe fruits, they did not oviposit on mature green fruits. Males did not show a preference for the volatiles from uninfested, artificially damaged, or infested Maha fruits, but females were more attracted to uninfested fruits than to artificially damaged and infested Maha fruits. Furthermore, females preferred to oviposit on uninfested fruits compared with artificially damaged fruit, and they did not oviposit on infested fruits. © The Authors 2015.

The majority of Australia's coal seam gas (CSG) reserves are in Queensland, where the industry has expanded rapidly in recent years. Despite concerns, health data have not been examined alongside CSG development. This study examined hospitalisation rates as a function of CSG development activity in Queensland, during the period 1995-2011. Admissions data were examined with CSG well numbers, which served as a proxy for CSG development activity. Time series models were used to assess changes in hospitalisation rates for periods of "low", "medium", "high", and "intense" activity compared to a period of "very low" activity, adjusting for covariates. "All-cause" hospitalisation rates increased monotonically with increasing gas well development activity in females (324.0 to 390.3 per 1000 persons) and males (294.2 to 335.4 per 1000 persons). Hospitalisation rates for "Blood/immune" conditions generally increased for both sexes. Female and male hospitalisation rates for "Circulatory" conditions decreased with increasing CSG activity. Hospitalisation rates were generally low for reproductive and birth outcomes; no clear associations were observed. This study showed some outcomes were associated with increasing CSG development activity. However, as a condition of data access, the population and outcomes were aggregated to a broad geographic study area rather than using higher geographic resolution data. Higher resolution data, as well as other data sources, should be explored. Further research should be conducted with an expanded time period to determine if these trends continue as the industry grows.

Salicylic Acid Induces Changes in Mango Fruit that Affect Oviposition Behavior and Development of the Oriental Fruit Fly, Bactrocera dorsalis.

Directory of Open Access Journals (Sweden)

Kamala Jayanthi Pagadala Damodaram

Full Text Available The Oriental fruit fly, Bactrocera dorsalis (Hendel is an important quarantine pest around the globe. Although measures for its control are implemented worldwide through IPM and male annihilation, there is little effect on their population. Hence, there is a need for new strategies to control this minacious pest. A strategy that has received negligible attention is the induction of 'natural plant defenses' by phytohormones. In this study, we investigated the effect of salicylic acid (SA treatment of mango fruit (cv. Totapuri on oviposition and larval development of B. dorsalis. In oviposition choice assays, gravid females laid significantly less eggs in SA treated compared to untreated fruit. Headspace volatiles collected from SA treated fruit were less attractive to gravid females compared to volatiles from untreated fruit. GC-MS analysis of the headspace volatiles from SA treated and untreated fruit showed noticeable changes in their chemical compositions. Cis-ocimene and 3-carene (attractants to B. dorsalis were reduced in the headspace volatiles of treated fruit. Further, reduced pupae formation and adult emergence was observed in treated fruit compared to control. Increased phenol and flavonoid content was recorded in treated fruit. We also observed differential expression of anti-oxidative enzymes namely catalase (CAT, polyphenoloxidase (PPO and peroxidase (POD. In summary, the results indicate that SA treatment reduced oviposition, larval development and adult emergence of B. dorsalis and suggest a role of SA in enhancing mango tolerance to B. dorsalis.

Flight control of fruit flies: dynamic response to optic flow and headwind.

Insects are magnificent fliers that are capable of performing many complex tasks such as speed regulation, smooth landings and collision avoidance, even though their computational abilities are limited by their small brain. To investigate how flying insects respond to changes in wind speed and surrounding optic flow, the open-loop sensorimotor response of female Queensland fruit flies ( Bactrocera tryoni ) was examined. A total of 136 flies were exposed to stimuli comprising sinusoidally varying optic flow and air flow (simulating forward movement) under tethered conditions in a virtual reality arena. Two responses were measured: the thrust and the abdomen pitch. The dynamics of the responses to optic flow and air flow were measured at various frequencies, and modelled as a multicompartment linear system, which accurately captured the behavioural responses of the fruit flies. The results indicate that these two behavioural responses are concurrently sensitive to changes of optic flow as well as wind. The abdomen pitch showed a streamlining response, where the abdomen was raised higher as the magnitude of either stimulus was increased. The thrust, in contrast, exhibited a counter-phase response where maximum thrust occurred when the optic flow or wind flow was at a minimum, indicating that the flies were attempting to maintain an ideal flight speed. When the changes in the wind and optic flow were in phase (i.e. did not contradict each other), the net responses (thrust and abdomen pitch) were well approximated by an equally weighted sum of the responses to the individual stimuli. However, when the optic flow and wind stimuli were presented in counterphase, the flies seemed to respond to only one stimulus or the other, demonstrating a form of 'selective attention'. © 2017.

To compare the frequency of and trends in healthy lifestyle factors between singles and couples. Cross-sectional data from annual surveys conducted from 2005-2014 were used. The pooled sample included 15,001 Australian adults (mean age: 52.9 years, 50% male, 74% couples) who participated in the annual Queensland Social Survey via computer-assisted telephone interviews. Relationship status was dichotomised into single and couple. Binary logistic regression was used to assess associations between relationship status, and the frequency of and trends in healthy lifestyle factors. Compared to singles, couples were significantly more likely to be a non-smoker (OR = 1.82), and meet recommendations for limited fast food (OR = 1.12), alcohol consumption (OR = 1.27) and fruit and vegetable intake (OR = 1.24). Fruit and vegetable intake was not significantly associated with relationship status after adjusting for the other healthy lifestyle factors. Conversely, couples were significantly less likely to be within a normal weight range (OR = 0.81). In both singles and couples, the trend data revealed significant declines in the rates of normal weight (singles: OR = 0.97, couples: OR = 0.97) and viewing TV for less than 14 hours per week (singles: OR = 0.85, couples: OR = 0.84), whilst non-smoking rates significantly increased (singles: OR = 1.12, couples: OR = 1.03). The BMI trend was no longer significant when adjusting for health behaviours. Further, in couples, rates of meeting recommendations for physical activity and fruit/vegetable consumption significantly decreased (OR = 0.97 and OR = 0.95, respectively), as did rates of eating no fast food (OR = 0.96). These trends were not significant when adjusting for the other healthy lifestyle factors. In singles, rates of meeting alcohol recommendations significantly increased (OR = 1.08). Health behaviour interventions are needed in both singles and couples, but relationship status needs to be considered in interventions

In 2011 an unprecedented epidemic of equine encephalitis occurred in south-eastern (SE) Australia following heavy rainfall and severe flooding in the preceding 2-4 months. Less than 6% of the documented cases occurred in Queensland, prompting the question of pre-existing immunity in Queensland horses. A small-scale serological survey was conducted on horses residing in one of the severely flood-affected areas of SE-Queensland. Using a flavivirus-specific blocking-ELISA we found that 63% (39/62) of horses older than 3 years were positive for flavivirus antibodies, and of these 18% (7/38) had neutralizing antibodies to Murray Valley encephalitis virus (MVEV), Kunjin virus (WNV(KUN)) and/or Alfuy virus (ALFV). The remainder had serum-neutralizing antibodies to viruses in the Kokobera virus (KOKV) complex or antibodies to unknown/untested flaviviruses. Amongst eight yearlings one presented with clinical MVEV-encephalomyelitis, while another, clinically normal, had MVEV-neutralizing antibodies. The remaining six yearlings were flavivirus antibody negative. Of 19 foals born between August and November 2011 all were flavivirus antibody negative in January 2012. This suggests that horses in the area acquire over time active immunity to a range of flaviviruses. Nevertheless, the relatively infrequent seropositivity to MVEV, WNV(KUN) and ALFV (15%) suggests that factors other than pre-existing immunity may have contributed to the low incidence of arboviral disease in SE-Queensland horses during the 2011 epidemic.

Female Project Managers' Workplace Problems: a Survey

Science.gov (United States)

Duong, Thuong Thi; Skitmore, Martin

This article examines the extent to which challenges in the workplace may cause female project managers to be in a significantly small minority. A survey of members of the Australian Institute of Project Management in Queensland is described. This compares the experiences and observations of both men and women on various issues related to technical and gender aspects in project management workplaces. The results show that although female project managers experience many problems, male project managers also experience most of the same problems. Likewise, there are also few differences between more and less experience, the level of management, and types of industries. The differences that do occur involve discrimination against women in general, differences in project management styles, and support from other project managers.

Full Text Available BACKGROUND: Mosquito-borne diseases are climate sensitive and there has been increasing concern over the impact of climate change on future disease risk. This paper projected the potential future risk of Barmah Forest virus (BFV disease under climate change scenarios in Queensland, Australia. METHODS/PRINCIPAL FINDINGS: We obtained data on notified BFV cases, climate (maximum and minimum temperature and rainfall, socio-economic and tidal conditions for current period 2000-2008 for coastal regions in Queensland. Grid-data on future climate projections for 2025, 2050 and 2100 were also obtained. Logistic regression models were built to forecast the otential risk of BFV disease distribution under existing climatic, socio-economic and tidal conditions. The model was applied to estimate the potential geographic distribution of BFV outbreaks under climate change scenarios. The predictive model had good model accuracy, sensitivity and specificity. Maps on potential risk of future BFV disease indicated that disease would vary significantly across coastal regions in Queensland by 2100 due to marked differences in future rainfall and temperature projections. CONCLUSIONS/SIGNIFICANCE: We conclude that the results of this study demonstrate that the future risk of BFV disease would vary across coastal regions in Queensland. These results may be helpful for public health decision making towards developing effective risk management strategies for BFV disease control and prevention programs in Queensland.

Background: Understanding how socioecological factors affect the transmission of dengue fever (DF) may help to develop an early warning system of DF. Objectives: We examined the impact of socioecological factors on the transmission of DF and assessed potential predictors of locally acquired and overseas-acquired cases of DF in Queensland, Australia. Methods: We obtained data from Queensland Health on the numbers of notified DF cases by local government area (LGA) in Queensland for the period 1 January 2002 through 31 December 2005. Data on weather and the socioeconomic index were obtained from the Australian Bureau of Meteorology and the Australian Bureau of Statistics, respectively. A Bayesian spatial conditional autoregressive model was fitted at the LGA level to quantify the relationship between DF and socioecological factors. Results: Our estimates suggest an increase in locally acquired DF of 6% [95% credible interval (CI): 2%, 11%] and 61% (95% CI: 2%, 241%) in association with a 1-mm increase in average monthly rainfall and a 1°C increase in average monthly maximum temperature between 2002 and 2005, respectively. By contrast, overseas-acquired DF cases increased by 1% (95% CI: 0%, 3%) and by 1% (95% CI: 0%, 2%) in association with a 1-mm increase in average monthly rainfall and a 1-unit increase in average socioeconomic index, respectively. Conclusions: Socioecological factors appear to influence the transmission of DF in Queensland, but the drivers of locally acquired and overseas-acquired DF may differ. DF risk is spatially clustered with different patterns for locally acquired and overseas-acquired cases. PMID:22015625

Background Chronic kidney disease (CKD) is recognized as a major public health problem in Australia with significant mortality, morbidity and economic burden. However, there is no comprehensive surveillance programme to collect, collate and analyse data on CKD in a systematic way. Methods We describe an initiative called CKD Queensland (CKD.QLD), which was established in 2009 to address this deficiency, and outline the processes and progress made to date. The foundation is a CKD Registry of all CKD patients attending public health renal services in Queensland, and patient recruitment and data capture have started. Results We have established through early work of CKD.QLD that there are over 11 500 CKD patients attending public renal services in Queensland, and these are the target population for our registry. Progress so far includes conducting two CKD clinic site surveys, consenting over 3000 patients into the registry and initiation of baseline data analysis of the first 600 patients enrolled at the Royal Brisbane and Women's Hospital (RBWH) site. In addition, research studies in dietary intake and CKD outcomes and in models of care in CKD patient management are underway. Conclusions Through the CKD Registry, we will define the distribution of CKD patients referred to renal practices in the public system in Queensland by region, remoteness, age, gender, ethnicity and socioeconomic status. We will define the clinical characteristics of those patients, and the CKD associations, stages, co-morbidities and current management. We will follow the course and outcomes in individuals over time, as well as group trends over time. Through our activities and outcomes, we are aiming to provide a nidus for other states in Australia to join in a national CKD registry and network. PMID:23115138

Haarsager, Jennie; Krishnasamy, Rathika; Gray, Nicholas A

2018-05-01

Commencement of haemodialysis with an arteriovenous fistula (AVF) or arteriovenous graft (AVG) is associated with improved survival compared with commencement with a central venous catheter. In 2011-2012, Queensland Health made incentive payments to renal units for early referred patients who commenced peritoneal dialysis (PD), or haemodialysis with an AVF/AVG. The aim of this study was to determine if pay for performance improved clinical care. All patients who commenced dialysis in Australia between 2009 and 2014 and were registered with the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) were included. A multivariable regression model was used to compare rates of commencing dialysis with a PD catheter or permanent AVF/AVG during the pay-for-performance period (2011-2012) with periods prior (2009-2010) and after (2013-2014). A total of 10 858 early referred patients commenced dialysis during the study period, including 2058 in Queensland. In Queensland, PD as first modality increased with time (P pay-for-performance period as reference, the odds ratio for commencement with PD or haemodialysis with an AVF/AVG in Queensland was 1.02 (95% CI 0.81-1.29) in 2009-2010 and 1.28 (95% CI 1.01-1.61) in 2013-2014. There was no change for the rest of Australia (0.97 95% CI 0.87-1.09 in 2009-2010 and 1.00 95% CI 0.90-1.11 in 2013-14). Pay for performance did not improve rates of commencement of dialysis with PD or an AVF/AVG during the payment period. A lag effect on clinical care may explain the improvement in later years. © 2017 Asian Pacific Society of Nephrology.

Evidence suggests the closure of maternity units is associated with an increase in babies born before arrival (BBA). To explore the association between the number of maternity units in Australia and Queensland by birthing numbers, BBA rate and geographic remoteness of the health district where the mother lives. A retrospective study utilised routinely collected perinatal data (1992-2011). Pearson correlation tested the relationship between BBA rate and number of maternity units. Linear regression examined this association over time. During 1992-2011, the absolute numbers (N=22,814) of women having a BBA each year in Australia increased by 47% (N=836-1233); and 206% (n=140-429) in Queensland. This coincided with a 41% reduction in maternity units in Australia (N=623-368=18 per year) and a 28% reduction in Queensland (n=129-93). BBA rates increased significantly across Australia, r=0.837, n=20 years, pmaternity units in Australia, r=-0.804, n=19 years, pmaternity units over a 20-year period across Australia and Queensland is significantly associated with increased BBA rates. The distribution is not limited to rural and remote areas. Given the high risk of adverse maternal and neonatal outcomes associated with BBA, it is time to revisit the closure of units.

Tilbury, Trudy; Sanderson, Liz

2012-01-01

Queensland Mining has a strong focus on safety performance, but risk management of health, including Musculoskeletal Disorders (MSDs) continues to have a lower priority. The reliance on individual screening of workers and lower level approaches such as manual handling training is part of the coal mining 'culture'. Initiatives such as the New South Wales and Queensland Mining joint project to develop good practice guidance for mining has allowed for a more consistent message on participatory ergonomics and prevention of MSD. An evidence based practice approach, including the introduction of participatory ergonomics and safe design principles, was proposed to Anglo American Coal operations in Queensland. The project consisted of a skills analysis of current health personnel, design of a facilitated participatory ergonomics training program, site visits to identify good practice and champions, and a graduated mentoring program for health personnel. Early results demonstrate a number of sites are benefiting from site taskforces with a focus on positive performance outcomes.

2017-01-24

The overall mortality rate for cancer has declined in Australia. However, socioeconomic inequalities exist and the out-of-pocket costs incurred by patients in Australia are high compared with some European countries. There is currently no readily available data set to provide a systematic means of measuring the out-of-pocket costs incurred by patients with cancer within Australia. The primary aim of the project is to quantify the direct out-of-pocket healthcare expenditure of individuals in the state of Queensland, who are diagnosed with cancer. This project will build Australia's first model (called CancerCostMod) of out-of-pocket healthcare expenditure of patients with cancer using administrative data from Queensland Cancer Registry, for all individuals diagnosed with any cancer in Queensland between 1 July 2011 and 30 June 2012, linked to their Admitted Patient Data Collection, Emergency Department Information System, Medicare Benefits Schedule and Pharmaceutical Benefits Scheme records from 1 July 2011 to 30 June 2015. No identifiable information will be provided to the authors. The project will use a combination of linear and logistic regression modelling, Cox proportional hazards modelling and machine learning to identify differences in survival, total health system expenditure, total out-of-pocket expenditure and high out-of-pocket cost patients, adjusting for demographic and clinical confounders, and income group, Indigenous status and geographic location. Results will be analysed separately for different types of cancer.

Bartlett, Lynne M; Nowak, Madeleine J; Ho, Yikhong

2013-01-01

In Australia, faecal incontinence, the involuntary loss of liquid or solid stool with or without a person's awareness, has been reported in 8% of the South Australian and 11% of the urban New South Wales community-dwelling populations. Studies conducted in 2004 and 2005 reported faecal incontinence in more than 20% of colorectal and urogynaecological clinic patients at Townsville Hospital (a referral centre serving rural North Queensland). This prompted concern regarding the level of faecal incontinence in the community. The aim of this study was to investigate the prevalence of faecal incontinence in the North and Far North Queensland urban and rural communities. The sample size was based on the New South Wales postal surveys (11% prevalence). Higher rates were expected in North/Far North Queensland, so prevalence there was estimated at 12.1% (confidence interval ± 2%, ie the true level to be between 10.1% and 14.1%). The sample for each of the Townsville, Cairns (in Far North Queensland) and rural/remote settings was calculated at 1022. The database for the present study was compiled using a systematic randomised process selecting two private names from each column on each page of the Cairns and Townsville White Pages® (Cairns: 1112 urban, 481 rural, 226 remote; Townsville: 1049 urban, 432 rural, 320 remote). The questionnaire covered personal demographics, health/risk factors, bowel habits, nutrition (fibre and fluid intake) and physical activity. Faecal incontinence was defined as accidental leakage of solid or liquid stool in the past 12 months that was not caused by a virus, medication or contaminated food. To improve the response rate a participation incentive of a chance to win a $250 voucher or one of ten $50 vouchers was offered in the initial mail-out. The initial survey was mailed out in July 2007; two follow-up surveys were mailed out to non-responders in September 2007 and January 2008. One hundred randomly selected non-responders were telephoned in

The implementation and development of complex alcohol control policies in indigenous communities in Queensland (Australia).

Science.gov (United States)

Clough, Alan R; Bird, Katrina

2015-04-01

Very high rates of injury and death during the 1990s were linked with increased alcohol availability and misuse in discrete Indigenous communities in rural and remote Queensland (Australia). To address widespread concerns about a public health crisis, from 2002, the Queensland Government implemented alcohol control strategies known as 'Alcohol Management Plans' (AMPs) in 19 of these communities. Although resources for prevention and treatment were promised, AMPs became increasingly focused on local prohibition, restricted access to alcohol and punitive measures for breaching restrictions. An examination of legislation, regulations, explanatory notes, and published documents indicates this focus evolved across four phases since 2002. The first phase, from 2002 to 2004, saw 'restricted areas' with alcohol 'carriage limits' introduced, restricting the amounts and types of liquor permitted within some communities. The second phase (2002-2007) featured evaluations and reviews by the Queensland Government bringing recommendations for more stringent controls. Additionally, beyond the 'restricted areas', licenced premises situated within the 'catchments' of the targeted communities, mainly located in the nearby regional towns, became subject to 'minimising harm' provisions. These more stringent controls were implemented widely in the third phase (2008-2011) when: the operations of seven community-managed liquor outlets were terminated; the trading arrangements of two others were modified; Police powers to search and seize were increased; and 'attempting' to take liquor into a 'restricted area' also became an offence. Some communities have seen a reduction in alcohol-related harms that have been attributed to these alcohol control strategies. This commentary maps the recent regulatory history of Queensland's alcohol controls targeting discrete Indigenous communities highlighting their increasing focus on punitive measures to reduce access to alcohol.

Positive attitudes of healthcare staff towards people with dementia promote higher quality care, although little is known about important factors that underlie positive attitudes. Key aims of this project were to explore the relationships between staff attitudes towards dementia, self-confidence in caring for people with dementia, experience and dementia education and training. A brief online survey was developed and widely distributed to registered nurses and allied health professionals working in Queensland in 2012. Regression analyses were performed to identify important predictors of self-confidence in caring for people with dementia and positive attitudes towards people with dementia. Five hundred and twenty-four surveys were completed by respondents working in a range of care settings across Queensland. Respondents were predominantly female (94.1%), and most were registered nurses (60%), aged between 41 and 60 years (65.6%). Around 40% regularly worked with people with dementia and high levels of self-confidence in caring for this population and positive attitudes towards people with dementia were reported. The majority of respondents (67%) had participated in a dementia education/training activity in the past 12 months. More experience working with people with dementia predicted greater self-confidence while recent participation in a dementia education/training and higher self-confidence in caring for a person with dementia significantly predicted more positive attitudes towards people with dementia. These results confirm the importance of self-confidence and dementia education in fostering positive attitudes and care practices towards people with dementia. Our results also indicate that the demand for ongoing dementia education is high amongst health care workers and it is recommended that regular dementia education/ training be provided and promoted for all healthcare personnel who work with people with dementia.

2008-09-01

Full Text Available Abstract Background Cross national drug utilization studies can provide information about different influences on physician prescribing. This is important for medicines with issues around safety and quality of use, like non selective non-steroidal anti-inflammatory drugs (ns-NSAIDs and cyclo-oxygenase-2 (COX-2 inhibitors. To enable comparison of prescription medicine use across different jurisdictions with a range of population sizes, data first need to be compared within Australia to understand whether use in a smaller sub-population may be considered as representative of the total use within Australia. The aim of this study was to compare the utilization of non selective NSAID, COX-2 inhibitors and paracetamol between Queensland and Australia. Method Dispensing data were obtained for concession beneficiaries for Australia for ns-NSAIDs, COX-2 inhibitors and paracetamol subsidized by the PBS over the period 1997–2003. The same data were purchased for Queensland. Data were converted to Defined Daily Dose (DDD/1000 beneficiaries/day (World Health Organization anatomical therapeutic chemical classification, 2005. Results Total NSAID and paracetamol consumption were similar in Australia and Queensland. Ns-NSAID use decreased sharply with the introduction of COX-2 inhibitors (from approximately 80 to 40 DDD/1000 beneficiaries/day. Paracetamol was constant (approximately 45 DDD/1000 beneficiaries/day. COX-2 inhibitors consumption was initially higher in Queensland than in the whole of Australia. Conclusion Despite initial divergence in celecoxib use between Queensland and Australia, the use of ns-NSAIDs, COX-2 inhibitors and paracetamol overall, in concession beneficiaries, was comparable in Australia and Queensland.

Leptospirosis is an emerging infectious disease, with increasing frequency and severity of outbreaks, changing epidemiology of populations at risk, and the emergence of new serovars. Environmental drivers of disease transmission include flooding, urbanisation, poor sanitation, changes in land use and agricultural practices, and socioeconomic factors. In Queensland, human infection with Leptosira borgpetersenii serovar Arborea was first reported in 2001. This study aims to report the emergence of serovar Arborea in Queensland from 2001 to 2013, and investigate potential risk factors for infection and drivers of emergence. Data on laboratory-confirmed cases of human leptospirosis in Queensland were obtained from the enhanced surveillance system at the WHO/FAO/OIE Collaborating Centre for Reference and Research on Leptospirosis in Brisbane, Australia. The changing epidemiology of serovar Arborea from 2001 to 2003 was described with respect to case numbers, proportion of leptospirosis cases attributed to the serovar, and geographic distribution. Differences in risk factors for the most common serovars were compared. During this period, 1289 cases of leptospirosis were reported, including 233 cases attributed to serovar Arborea. Risk factors for infection include male gender (91 % of cases), occupation, and recreational exposure. Most common occupations recorded were banana workers (28.4 %), meat workers (7.2 %), dairy farmers (5.8 %), graziers/stockmen (5.5 %), 'other agricultural/rural workers' (16.4 %), and tourists or tourism operators (4.6 %). Time trend analysis showed that while non-Arborea cases decreased over the study period, Arborea cases increased by 3.4 cases per year. The proportion of annual cases attributed to Arborea peaked at 49 % in 2011 after unprecedented flooding in Queensland. Mapping of cases by residential location showed expansion of the geographic range of serovar Arborea, concentrating mostly around Brisbane, Cairns and Innisfail. Serovars

Feral pigs occur throughout tropical far north Queensland, Australia and are a significant threat to biodiversity and World Heritage values, agriculture and are a vector of infectious diseases. One of the constraints on long-lasting, local eradication of feral pigs is the process of reinvasion into recently controlled areas. This study examined the population genetic structure of feral pigs in far north Queensland to identify the extent of movement and the scale at which demographically independent management units exist. Genetic analysis of 328 feral pigs from the Innisfail to Tully region of tropical Queensland was undertaken. Seven microsatellite loci were screened and Bayesian clustering methods used to infer population clusters. Sequence variation at the mitochondrial DNA control region was examined to identify pig breed. Significant population structure was identified in the study area at a scale of 25 to 35 km, corresponding to three demographically independent management units (MUs). Distinct natural or anthropogenic barriers were not found, but environmental features such as topography and land use appear to influence patterns of gene flow. Despite the strong, overall pattern of structure, some feral pigs clearly exhibited ancestry from a MU outside of that from which they were sampled indicating isolated long distance dispersal or translocation events. Furthermore, our results suggest that gene flow is restricted among pigs of domestic Asian and European origin and non-random mating influences management unit boundaries. We conclude that the three MUs identified in this study should be considered as operational units for feral pig control in far north Queensland. Within a MU, coordinated and simultaneous control is required across farms, rainforest areas and National Park Estates to prevent recolonisation from adjacent localities.

In 2011, the Australian Commission on Safety and Quality in Health Care (ACSQHC) recommended that all hospitals in Australia must have an Antimicrobial Stewardship (AMS) program by 2013. Nevertheless, little is known about current AMS activities. This study aimed to determine the AMS activities currently undertaken, and to identify gaps, barriers to implementation and opportunities for improvement in Queensland hospitals. The AMS activities of 26 facilities from 15 hospital and health services in Queensland were surveyed during June 2012 to address strategies for effective AMS: implementing clinical guidelines, formulary restriction, reviewing antimicrobial prescribing, auditing antimicrobial use and selective reporting of susceptibility results. The response rate was 62%. Nineteen percent had an AMS team (a dedicated multidisciplinary team consisting of a medically trained staff member and a pharmacist). All facilities had access to an electronic version of Therapeutic Guidelines: Antibiotic, with a further 50% developing local guidelines for antimicrobials. One-third of facilities had additional restrictions. Eighty-eight percent had advice for restricted antimicrobials from in-house infectious disease physicians or clinical microbiologists. Antimicrobials were monitored with feedback given to prescribers at point of care by 76% of facilities. Deficiencies reported as barriers to establishing AMS programs included: pharmacy resources, financial support by hospital management, and training and education in antimicrobial use. Several areas for improvement were identified: reviewing antimicrobial prescribing with feedback to the prescriber, auditing, and training and education in antimicrobial use. There also appears to be a lack of resources to support AMS programs in some facilities. WHAT IS KNOWN ABOUT THE TOPIC?: The ACSQHC has recommended that all hospitals implement an AMS program by 2013 as a requirement of Standard 3 (Preventing and Controlling Healthcare

Fruit flies are major constraint to fruit production in Mauritius. The peach fruit fly, Bactrocera zonata (Saunders), the natal fly, Ceratitis rosa (Karsch), the medfly, C. capitata (Wiedmann) are the main pests of fleshy fruits. Fruit fly trapping trials were conducted in backyards to find the most effective combination of attractant and lures for females. There were two separate trapping trials, carried out in two different localities during the period November 2004 to March 2005. In the first trial, the attractants in different combinations were tested in International Pheromone McPhail Trap (IPMT). The attractants were as follows: three patches containing Ammonium Acetate (AA) + Trimethylamine (TMA) + Putrescine (PT); Two patches of AA ; two patches of AA + one patch of PT ; two patches of AA + one patch of TMA; one patch of solbait; torula tablets; protein hydrolysate and GF120. Water and Triton B were used as retention device in traps baited with the patches. In the first trial, all treatments were equally effective in the capture of either female B. zonata or female C. capitata with the exception of protein hydrolysate and GF120 which trapped fewer numbers of flies. In the second trapping trial, additional trap types and lure combinations were assessed. The three component lure (AA + PT + TMA with water/Triton as retention device in IPMT) and the trap baited with Waste Brewer's Yeast captured significantly more female flies followed by IPMT with AA + PT + TMA / Sticky insert and the Easy trap. In all trials, females accounted for more than 75% of the catches. (author)

Cottrill, D A; Ribbe, J

2010-01-01

Much of southern and eastern Australia including Queensland have experienced rainfall declines over recent decades affecting agricultural production and accelerating water infrastructure development. Rainfall declines from southern Australia have now been directly related to changes in the Southern Annular Mode (SAM) and the subtropical ridge. In southern and coastal Queensland, the rainfall declines have occurred mostly in the austral summer and autumn. Observations from this region reveal the rainfall decline is correlated to an increase in the mean sea level pressure (MSLP) at many stations. The largest increases in MSLP are over southeast Queensland and coastal regions, where some of the largest rainfall declines occur. This study indicates the subtropical ridge as one of the main factors in the rainfall decline over this region. SAM is also likely to be important, although its seasonal influence, apart from winter, is harder to determine.

A cadaver study to estimate the prevalence of dental disorders in horses presented at an abattoir in Queensland, Australia. Cadaver heads at a Queensland abattoir were examined for the presence of dental abnormalities and categorised into age groups. The prevalence of abnormalities was analysed by binomial observation of observed proportion, Pearson's Chi-square test or Fisher's exact correlation test. Strength of association was evaluated using Cramer's V test. Heads from horses (n=400) estimated to be between 1 and 30 years of age were placed into four age groups. The most common abnormalities were sharp enamel points (55.3%) and hooks (43%). The highest frequency of dental diseases and abnormalities were in horses 11-15 years old (97.5%). Common abnormalities were found in all groups and the prevalence increased with age. This study suggests that all horses should have regular complete dental examinations to detect and treat dental disorders in order to limit more severe dental pathologies later in life. © 2015 Australian Veterinary Association.

Oviposition preference hierarchy in Ceratitis capitata (Diptera, Tephritidae: influence of female age and experience

Full Text Available The influence of two factors, age and previous experience, on the oviposition hierarchy preference of Ceratitis capitata (Wiedemann, 1824 females was studied. Two populations were analyzed: one reared in laboratory during 17 years and the other captured in nature. In the first experiment the oviposition preference for four fruits, papaya, orange, banana and apple was tested at the beginning of oviposition period and 20 days past. The results showed that the wild females as much the laboratory ones had an oviposition preference hierarchy at the beginning of peak period of oviposition. However this hierarchic preference disappeared in a later phase of life. In the second experiment the females were previously exposed to fruits of different hierarchic positions and afterwards their choice was tested in respect to the oviposition preference for those fruits. The results showed that there was an influence of the previous experience on the posterior choice of fruits to oviposition when the females were exposed to fruits of lower hierarchic position.

We implemented a community telehealth project in the three towns in the Darling Downs area of Queensland over a 2-year period starting in July 2012. The purpose of the project was to generate telehealth activity in hospitals, general practice and selected residential aged care facilities. Telehealth education and training was provided to clinicians in the three towns and a community awareness campaign was delivered using advertisements in newspapers, messages in social media and presentations at community events. A total of 55 stakeholders were engaged with during 61 site visits to health care facilities during the first two years of the project. During the study period, telehealth activity in Queensland increased in the hospital sector by 39% and in the non-hospital sector by 99%. In the Darling Downs region, telehealth activity in the hospital sector increased by 104%, compared to 28% in the rest of Queensland. However, in the non-hospital sector, the increase in telehealth activity in the Darling Downs region was similar to the rest of Queensland. Telehealth services established and/or facilitated by the project included specialist geriatric ward rounds in Dalby, Chinchilla and Miles for patients in the local hospitals and nursing homes; and ad-hoc teleconsultations for children and adults living in these communities, with specialists at Toowoomba and hospitals in Brisbane. An increase in telehealth implies better access to a range of clinical services, which may result in improved clinical outcomes for patients. © The Author(s) 2014 Reprints and permissions:]br]sagepub.co.uk/journalsPermissions.nav.

Sea turtle fibropapillomatosis (FP) is a disease marked by the proliferation of benign but debilitating cutaneous and occasional visceral tumors, likely to be caused by chelonid alphaherpesvirus 5 (ChHV5). This study presents a phylogeny of ChHV5 strains found on the east coast of Queensland, Australia, and a validation for previously unused primers. Two different primer sets (gB-1534 and gB-813) were designed to target a region including part of the UL27 glycoprotein B (gB) gene and part of UL28 of ChHV5. Sequences obtained from FP tumors found on juvenile green turtles Chelonia mydas (Queensland, and Queensland clusters. The clusters reflect the collection sites on the east coast of Queensland with a definitive north-south trend. Received October 22, 2016; accepted May 7, 2017.

The dangers associated with horse riding, a popular activity throughout Australia, are well documented; yet, few studies have comprehensively described injuries caused by horses to nonriders. This study aimed to facilitate targeted injury prevention strategies and appropriate trauma management by describing all horse-related injuries, for both riders and nonriders, in Queensland, and identifying those at greatest risk. Horse-related injury data from 2005 to 2009 were extracted from the Queensland Trauma Registry. Descriptive comparisons were undertaken for demographic, injury, and acute care characteristics between riders and nonriders, between pediatric and adult cases, and between sports/leisure and work injuries. The relative risk of surgery by sex and between riders and nonriders was assessed. More than 25% of injuries occurred in people not riding a horse. Nonriders sustained a significantly higher proportion of internal organ injuries, open wounds, as well as facial and pelvic/abdominal injuries. Females accounted for more than 80% of children who were injured while riding a horse. For adults, 25% were injured while working, and more than 66% of injured workers were male. Injuries most commonly occurred in regional areas. Surgery was most common among children, nonriders, and those with Injury Severity Score (ISS) of 1 to 8. The likelihood of surgery was 25% higher for nonriders (95% confidence interval, 1.14-1.38%). Horse-related injuries are most prevalent in identifiable populations, particularly young female riders and adult males injured while working. Injuries inflicted by horses to nonriders contribute more than 27% of all horse-related injuries; however, most previous research has been limited to injured riders. Compared with riders, nonriders more frequently sustain internal, facial, and pelvic injuries; are male; and undergo surgery. The results of this study may be used to tailor prevention strategies and inform trauma management specific to the

To describe chronic conditions and injuries as a proportion of total emergency presentations to a large public hospital in regional Queensland, and to investigate differences in presentation rates associated with Indigenous status. Cross-sectional analysis using Emergency Department Information System data between 1 July 2012 and 30 June 2014. Regional Queensland, Australia. A total of 95 238 emergency presentations were generated by 50 083 local residents living in the 10 statistical local areas (SLAs) immediately around the hospital. Emergency presentations for chronic conditions and injuries identified from discharge ICD-10-AM principal diagnosis. Age-standardised presentation rates were calculated using the Australian 2001 reference population. Approximately half of all presentations were for chronic conditions (20.2%) and injuries (28.8%). Two-thirds of all chronic condition presentations were for mental and behavioural disorders (34.6%) and circulatory diseases (33.2%). Head injuries accounted for the highest proportion of injuries (18.9%). Age-standardised rates for major diagnostic groups were consistently higher for Indigenous residents, whose presentations were lower in mean age (95% CI) by 7.7 (7.3-8.1) years, 23% less likely to be potentially avoidable GP-type presentations [RR (95% CI) = 0.77 (0.75-0.80)], 30% more likely to arrive by ambulance [1.31 (1.28-1.33)] and 11% more likely to require hospital admission [1.11 (1.08-1.13)]. Opportunities exist to enhance current coordinated hospital avoidance and primary health services in regional Queensland targeting common mental and circulatory disorders, especially for Indigenous Australians. © 2016 The Authors.

Hypertension and other chronic disease risks are common among Aboriginal and Torres Strait Islander adults but there is little evidence regarding the epidemiology of these risk factors during adolescence. This study examines the prevalence of pre-hypertension, hypertension and other cardiovascular risk factors in Aboriginal and Torres Strait Islander people aged 15-24 years living in remote Indigenous communities in north Queensland. In so doing, it aims to better inform the approach to cardiovascular disease in this population. This is a descriptive study that retrospectively examines health service data from a program of community screening, the Young Persons Check (YPC). Participants were 1,883 Aboriginal and Torres Strait Islander people aged 15-24 years who attended for a YPC in 11 remote communities in north Queensland between March 2009 and April 2011. Overall, the prevalence of pre-hypertension was 34.0%; stage I hypertension was 17.7% and stage II hypertension was 3.3%. The prevalence of elevated waist circumference was 47.6%, overweight or obesity 45.9%, elevated triglycerides 18.3%, decreased HDL 54.8% and proteinuria 24.3%. The prevalence of hypertension (stage I or II) among Torres Strait Islander males was 34.1%, Aboriginal males 26.9%, Torres Strait Islander females 12.6% and Aboriginal females 13.0%. Hypertension was associated with sex (males) (OR= 4.37, p<0.000), overweight (OR=2.46, p<0.000), obesity (OR=4.59, p<0.000) and elevated triglycerides (OR=2.38, p<0.000). Pre-hypertension, hypertension and other cardiovascular risk in this population is highly prevalent. Hypertension was particularly prevalent among male participants. The results reiterate the importance of early life experience in cardiovascular disease prevention. © 2015 The Authors.

The oral health of rural Australians continues to lag behind that of those living in metropolitan areas. Research has shown that people living in rural areas are more likely to suffer from dental caries (decay), visit the dentist less often and have poorer access to oral health services. The purpose of the study was to examine hospitalisations for dental conditions and utilisation of public dental services in three rural communities in Queensland compared with the whole of Queensland. Aggregated hospitalisation data for dental conditions and counts of public outpatient service data were requested for residents of three rural communities in Queensland and for the whole of Queensland for the calendar year 2013. Hospitalisation rates per 1000 and risk ratios were calculated to examine the risk of hospitalisation for dental procedures for those living in the selected rural communities and the rest of Queensland. Data were grouped by gender, age and Indigenous status and comparisons made between Queensland and the rural communities. Outpatient service data were converted to percentage of all services delivered to allow comparisons between groups of different sizes. Population data were grouped into age cohorts and compared with the proportion of public oral health services delivered to each age cohort. Residents of the rural communities were twice as likely to be hospitalised and children aged 0-14 years living in the communities were three times more likely to be hospitalised for dental conditions compared to residents of the rest of Queensland. Outpatient oral service data showed that the proportion of services delivered to children aged up to 14 years living in the rural communities was less than the whole of Queensland. Interestingly, in one rural community where the public dental service was open to all, the distribution of public oral health services aligned with the age distribution of the population. The study showed that residents of these rural communities

Tachi, S.; Subahar, S

1998-12-16

The objective of this research is to test a hypothesis whether methyl eugenol has a benefit in sexual selection of fruit flies and to find at what age the male flies respond to methyl eugenol. This test was conducted using carambola fruit fly (Bractocera carambolae) at Inter University Center for Life Science of ITB. The results of the tests are summarized as follows ; 1. Males started to respond to methyl eugenol at the age of 11 days old and the maximum number of males were recorded on 14 and 15 days old. 2. Most of the carambola fruit fly start to respond to methyl eugenol before they become sexually mature. 3. A very small percentage of newly emerged males (less than 1%) survive to mate with females during treatment with methyl eugenol. Methyl eugenol has benefit in sexual selection of carabola fruit fly, i.e., males responded to methyl eugenol before they engage in sexual activities, while females responded to methyl eugenol only when males started their mating activities.

To explore whether area-level socio-economic position or the form of retail stream (conventional v. farmers' market) is associated with differences in the price, availability, variety and quality of a range of fresh fruit and vegetables. A multi-site cross-sectional pilot study of farmers' markets, supermarkets and independent fruit and vegetable retailers. Each was surveyed to assess the price, availability, variety and quality of fifteen fruit and eighteen vegetable items. Retail outlets were located in south-east Queensland. Fifteen retail outlets were surveyed (five of each retail stream). Average basket prices were not significantly different across the socio-economic spectrum, but prices in low socio-economic areas were cheapest. Availability, variety and quality did not differ significantly across levels of socio-economic position; however, the areas with the most socio-economic disadvantage scored poorest for quality and variety. Supermarkets had significantly better fruit and vegetable availability than farmers' markets, although price, variety and quality scores were not different across retail streams. Results demonstrate a trend to fruit and vegetable prices being more expensive at farmers' markets, with the price of the fruit basket being significantly greater at the organic farmers' market compared with the non-organic farmers' markets. Neither area-level socio-economic position nor the form of retail stream was significantly associated with differences in the availability, price, variety and quality of fruit and vegetables, except for availability which was higher in supermarkets than farmers' markets. Further research is needed to determine what role farmers' markets can play in affecting fruit and vegetable intake.

Although pesticide resistance is common in insect vectors of human diseases, the evolution of resistance might be delayed if management practices are adopted that limit selection of resistance alleles. Outbreaks of dengue fever have occurred in Queensland, Australia, since the late 1800s, leading to ongoing attempts to control the mosquito vector, Aedes aegypti (L.). Since the 1990s, pyrethroid insecticides have been used for this purpose, but have been applied in a strategic manner with a variety of delivery methods including indoor residual spraying, lethal ovitraps, and use of insect growth regulators as larvicides. Separate selection experiments on mosquitoes from Queensland using Type I and Type II pyrethroids did not produce resistant lines of Ae. aegypti, and bioassays of field material from Queensland showed only weak tolerance in comparison with a susceptible line. There was no evidence of knockdown resistance (kdr) mutations in Ae. aegypti from Queensland, in stark contrast to the situation in nearby southeast Asia. We suspect that careful management of pyrethroid insecticide use combined with surveillance and interception of exotic incursions has helped to maintain pyrethroid (and particularly kdr-based) susceptibility in Ae. aegypti in Australia. © The Authors 2017.

2016-03-01

Various policies, plans and initiatives have been implemented to provide safe, quality and culturally competent care to patients within Queensland's health care system. A series of models of maternity care are available in Queensland that range from standard public care to private midwifery care. The current study aimed to determine whether identifying as culturally or linguistically diverse (CALD) was associated with the perceived safety, quality and cultural competency of maternity care from a consumer perspective, and to identify specific needs and preferences of CALD maternity care consumers. Secondary analysis of data collected in the Having a Baby in Queensland Survey 2012 was used to compare the experiences of 655 CALD women to those of 4049 non-CALD women in Queensland, Australia, across three stages of maternity care: pregnancy, labour and birth, and after birth. After adjustment for model of maternity care received and socio-demographic characteristics, CALD women were significantly more likely than non-CALD women to experience suboptimal staff technical competence in pregnancy, overall perceived safety in pregnancy and labour/birth, and interpersonal sensitivity in pregnancy and labour/birth. Approximately 50 % of CALD women did not have the choice to use a translator or interpreter, or the gender of their care provider, during labour and birth. Thirteen themes of preferences and needs of CALD maternity care consumers based on ethnicity, cultural beliefs, or traditions were identified; however, these were rarely met. Findings imply that CALD women in Queensland experience disadvantageous maternity care with regards to perceived staff technical competence, safety, and interpersonal sensitivity, and receive care that lacks cultural competence. Improved access to support persons, continuity and choice of carer, and staff availability and training is recommended.

Tariq, R.M.

2014-01-01

A field study was carried during January 2011 to March, 2013, to confirm the origin and evolution of female plant from an identical male plant in, a dioecious plant, the Carica papaya L. The plants were grown from the seeds of a normal female plant fruit. The grown, plants were identified as XX, XY and XYh (in March - April, 2012) on the basis of male and female flower bearing. The identical male plants, which usually bear only male (unisexual) flowers having calyx, corrolla and androecium, were observed also to bear bisexual flower, having calyx, corrolla, and gynoecium (ovary fused with androecium ). The fruits were set having the bisexual flowers in the identical male (hermaphrodite) plant. These fruits were kept under observation from setting to ripening stage. The ripened fruits were harvested from the identical male plants and 90-95% fruits from these plants were found with the seeds. Plants grown from these male fruit seeds produced all three type of plants i.e., male, female and hermaphrodite. This study indicated that an identical male (XYh) plant produced the female (XX) plant naturally, because of the XXY= XYh condition, which can contribute basic genetic material to male and female plants i.e an identical male (XYh = XXY= 2N +1 = 18+1= 19) produced all three type of plants, the pure male, the hermaphrodite and the female plant, originated from a single source of an identical male, as shown here. XYh = XXY g XY + XX + XXY. The propagation of all three sexes of Carica papaya from a single source of an identical male plant seeds is the first report in the world. (author)

To measure changes in cardiovascular risk factors among patients with coronary heart disease (CHD) and/or type 2 diabetes enrolled in a centralised statewide coaching program delivered by telephone and mail-out in the public health sector in Queensland. A population-based audit of cardiovascular risk factor data collected prospectively as part of The COACH (Coaching Patients On Achieving Cardiovascular Health) Program (TCP) delivered through Queensland Health's Health Contact Centre. 1962 patients with CHD and 707 patients with type 2 diabetes who completed TCP from 20 February 2009 to 20 June 2013, of whom 145 were Indigenous Australians. Changes in fasting lipids, fasting glucose, glycosylated haemoglobin levels, blood pressure, body weight, body mass index, smoking, alcohol consumption and physical activity, as measured at entry to and completion of the program. Statistically significant improvements in cardiovascular risk factor status, from entry to completion of the program, were found across all biomedical and lifestyle factors in patients with CHD and/or type 2 diabetes. For both diseases, improvements in serum lipids, blood glucose, smoking habit and alcohol consumption combined with increases in physical activity were the most notable findings. Similar differences were found in mean change scores in cardiovascular risk factors between Indigenous and non-Indigenous Queenslanders. A centralised statewide coaching program delivered by telephone and mail-out overcomes obstacles of distance and limited access to health services and facilitates a guideline-concordant decrease in cardiovascular risk.

Revised Distribution of Bactrocera tryoni in Eastern Australia and Effect on Possible Incursions of Mediterranean Fruit Fly: Development of Australia's Eastern Trading Block.

Science.gov (United States)

Dominiak, Bernard C; Mapson, Richard

2017-12-05

Bactrocera tryoni (Froggatt) (Diptera: Tephritidae), commonly called 'Queensland fruit fly' in Australia, and Mediterranean fruit fly (Ceratitis capitata Wiedemann) (Diptera: Tephritidae) are the two most economically important fruit fly in Australia with B. tryoni in the east and Mediterranean fruit fly in the west. The two species coexisted for several decades, but it is believed that B. tryoni displaced Mediterranean fruit fly. In southeastern Australia, this was deemed inadequate for export market access, and a large fruit fly free zone (fruit fly exclusion zone) was developed in 1996 where B. tryoni was eradicated by each state department in their portion of the zone. This zone caused an artificial restricted distribution of B. tryoni. When the fruit fly exclusion zone was withdrawn in Victoria and New South Wales in 2013, B. tryoni became endemic once again in this area and the national distribution of B. tryoni changed. For export markets, B. tryoni is now deemed endemic to all eastern Australian states, except for the Greater Sunraysia Pest-Free Area. All regulatory controls have been removed between eastern states, except for some small zones, subject to domestic market access requirements. The eastern Australian states now form a B. tryoni endemic trading group or block. All Australian states and territories maintain legislation to regulate the movement of potentially infested host fruit into their states. In particular, eastern states remain active and regulate the entry of commodities possibly infested with Mediterranean fruit fly. The combination of regulatory controls limits the chances of Mediterranean fruit fly entering eastern states, and if it did, Mediterranean fruit fly is unlikely to establish in the opposition to a well-established B. tryoni population. © The Author(s) 2017.

Full Text Available Influence of different tropical fruits on biological and behavioral aspects of the Mediterranean fruit fly Ceratitis capitata (Wiedemann (Diptera, Tephritidae. Studies on Ceratitis capitata, a world fruit pest, can aid the implementation of control programs by determining the plants with higher vulnerability to attacks and plants able to sustain their population in areas of fly distribution. The objective of the present study was to evaluate the influence of eight tropical fruits on the following biological and behavioral parameters of C. capitata: emergence percentage, life cycle duration, adult size, egg production, longevity, fecundity, egg viability, and oviposition acceptance. The fruits tested were: acerola (Malpighia glabra L., cashew (Anacardium occidentale L., star fruit (Averrhoa carambola L., guava (Psidium guajava L., soursop (Annona muricata L., yellow mombin (Spondias mombin L., Malay apple (Syzygium malaccense L., and umbu (Spondias tuberosa L.. The biological parameters were obtained by rearing the recently hatched larvae on each of the fruit kinds. Acceptance of fruits for oviposition experiment was assessed using no-choice tests, as couples were exposed to two pieces of the same fruit. The best performances were obtained with guava, soursop, and star fruit. Larvae reared on cashew and acerola fruits had regular performances. No adults emerged from yellow mombin, Malay apple, or umbu. Fruit species did not affect adult longevity, female fecundity, or egg viability. Guava, soursop, and acerola were preferred for oviposition, followed by star fruit, Malay apple, cashew, and yellow mombin. Oviposition did not occur on umbu. In general, fruits with better larval development were also more accepted for oviposition.

A trend of higher suicide rates in rural and remote areas as well as areas with low socioeconomic status has been shown in previous research. Little is known whether the influence of social deprivation on suicide differs between urban and rural areas. This investigation aims to examine how social deprivation influences suicide mortality and to identify which related factors of deprivation have a higher potential to reduce suicide risk in urban and rural Queensland, Australia. Suicide data from 2004 to 2008 were obtained from the Queensland Suicide Register. Age-standardized suicide rates (15+ years) and rate ratios, with a 95% confidence interval, for 38 Statistical Subdivisions (SSDs) in Queensland were calculated. The influence of deprivation-related variables on suicide and their rural-urban difference were modelled by log-linear regression analyses through backward elimination. Among the 38 SSDs in Queensland, eight had a higher suicide risk while eleven had a lower rate. Working-age males (15-59 years) had the most pronounced geographic variation in suicide rate. In urban areas, suicide rates were positively associated with tenant households in public housing, Aboriginal and Torres Strait Islander people, the unemployment rate and median individual income, but inversely correlated with younger age and households with no internet access. In rural areas, only tenant households in public housing and households with no internet access heightened the risk of suicide, while a negative association was found for younger and older persons, low-skilled workers or labourers, and families with low income and no cars. The extent to which social deprivation contributes to suicide mortality varies considerably between rural and urban areas.

SUMMARY This study aimed to explore the spatio-temporal patterns, geographical co-distribution, and socio-ecological drivers of childhood pneumonia and diarrhoea in Queensland. A Bayesian conditional autoregressive model was used to quantify the impacts of socio-ecological factors on both childhood pneumonia and diarrhoea at a postal area level. A distinct seasonality of childhood pneumonia and diarrhoea was found. Childhood pneumonia and diarrhoea were mainly distributed in the northwest of Queensland. Mount Isa city was the high-risk cluster where childhood pneumonia and diarrhoea co-distributed. Emergency department visits (EDVs) for pneumonia increased by 3% per 10-mm increase in monthly average rainfall in wet seasons. By comparison, a 10-mm increase in monthly average rainfall may cause an increase of 4% in EDVs for diarrhoea. Monthly average temperature was negatively associated with EDVs for childhood diarrhoea in wet seasons. Low socioeconomic index for areas (SEIFA) was associated with high EDVs for childhood pneumonia. Future pneumonia and diarrhoea prevention and control measures in Queensland should focus more on Mount Isa.

Trapping guidelines for area-wide fruit fly programmes

International Nuclear Information System (INIS)

2003-11-01

Different traps and lures have been developed and used over decades to survey fruit fly populations. The first attractant for male fruit flies was methyl eugenol (ME) (for Bactrocera zonata, Howlett, 1912) followed by kerosene for Mediterranean fruit fly, Ceratitis capitata, (medfly), Severin and Severin, 1913. In 1956, Angelica seed oil was used to trap medfly (Steiner et al, 1957). Beroza et al. (1961) discovered trimedlure (TML) to be effective for the same purpose. Beroza and Green, 1963, demonstrated cuelure to be an effective attractant for Bactrocera cucurbitae. Food baits based on protein solutions, fermenting sugar solutions, fruit juices, and vinegar have been used since 1918 for the capture of females of several species. The McPhail trap was the first device to be used with protein baits (McPhail, 1929). Steiner traps were developed in 1957 (Steiner et al., 1957) and Jackson traps in 1971 for TML (Harris et al., 1971). These traps are currently used in various countries for fruit fly surveys in support of control activities and eradication campaigns. The combination of a McPhail trap with a protein attractant, Jackson trap with TML, and the Steiner trap with ME or cuelure (CUE), has remained unchanged for several decades. Global trends in increasing food quality, revenue sources, and fruit and vegetable trade, has resulted in an increased worldwide movement of fruit fly species and requires refinement of survey systems. After years of validating trapping technology through coordinated research programmes (CRP's) and extensive technical assistance to member countries, the Joint Division FAO/IAEA proposes the use of proven technologies in improving trap sensitivity in area-wide fruit fly control programmes (IAEA 1996 and IAEA 1998). These proven technologies include the use of synthetic food lures such as female attractants that can be used for several species of Anastrepha, Bactrocera and Ceratitis.

Undergraduate students studying the Bachelor of Radiation Therapy at Queensland University of Technology (QUT) attend clinical placements in a number of department sites across Queensland. To ensure that the curriculum prepares students for the most common treatments and current techniques in use in these departments, a curriculum matching exercise was performed. A cross-sectional census was performed on a pre-determined “Snapshot” date in 2012. This was undertaken by the clinical education staff in each department who used a standardized proforma to count the number of patients as well as prescription, equipment, and technique data for a list of tumour site categories. This information was combined into aggregate anonymized data. All 12 Queensland radiation therapy clinical sites participated in the Snapshot data collection exercise to produce a comprehensive overview of clinical practice on the chosen day. A total of 59 different tumour sites were treated on the chosen day and as expected the most common treatment sites were prostate and breast, comprising 46% of patients treated. Data analysis also indicated that intensity-modulated radiotherapy (IMRT) use is relatively high with 19.6% of patients receiving IMRT treatment on the chosen day. Both IMRT and image-guided radiotherapy (IGRT) indications matched recommendations from the evidence. The Snapshot method proved to be a feasible and efficient method of gathering useful data to inform curriculum matching. Frequency of IMRT use in Queensland matches or possibly exceeds that indicated in the literature. It is recommended that future repetition of the study be undertaken in order to monitor trends in referral patterns and new technology implementation

Aboriginal ‘resistance war’ tactics – ‘The Black War’ of southern Queensland

Directory of Open Access Journals (Sweden)

Raymond Constant Kerkhove

2015-02-01

Full Text Available Frontier violence is now an accepted chapter of Australian history.  Indigenous resistance is central to this story, yet little examined as a military phenomenon (Connor 2004.  Indigenous military tactics and objectives are more often assumed than analysed. Building on Laurie’s and Cilento’s contentions (1959 that an alliance of Aboriginal groups staged a ‘Black War’ across southern Queensland between the 1840s and 1860s, the author seeks evidence for a historically definable conflict during this period, complete with a declaration, coordination, leadership, planning and a broader objective: usurping the pastoral industry.   As the Australian situation continues to present elements which have proved difficult to reconcile with existing paradigms for military history, this study applies definitions from guerilla and terrorist conflict (e.g. Eckley 2001, Kilcullen 2009 to explain key features of the southern Queensland “Black War.” The author concludes that Indigenous resistance, to judge from southern Queensland, followed its own distinctive pattern.  It achieved coordinated response through inter-tribal gatherings and sophisticated signaling.  It relied on economic sabotage, targeted payback killings and harassment.  It was guided by reticent “loner-leaders.” Contrary to the claims of military historians such as Dennis (1995, the author finds evidence for tactical innovation.  He notes a move away from pitched battles to ambush affrays; the development of full-time ‘guerilla bands’; and use of new materials.

CKD.QLD: establishment of a chronic kidney disease [CKD] registry in Queensland, Australia.

Chronic kidney disease [CKD] is recognised as a global public health problem. Until recently, the majority of information informing on CKD has been generated from renal registries reporting on patients with end-stage kidney disease [ESKD] and on renal replacement therapy [RRT]. There has been a paucity of information on pre-dialysis CKD cohorts, and many issues related to these poorly described populations are unresolved. To this end, international organizations have called for CKD surveillance systems across all countries. In Australia, we have responded by developing the Chronic Kidney Disease in Queensland [CKD.QLD] with three main platforms consisting of CKD Registry, clinical trials and development of biobank. This registry which is the core component of CKD surveillance was conceptualized specifically for the pre-dialysis population in the public health system in Queensland, Australia. Recruitment started in May 2011, and to date the Registry has evolved as one of the largest CKD cohorts in the world with recruitment close to 7000 patients. The Registry has had many outcomes, including being the nidus for Australia's first National Health and Medical Research Council [NHMRC] CKD Centre of Research Excellence [CKD.CRE]. The Registry, with its linkage to Queensland Health datasets, is reporting, and is expected to continue generating, significant information on multiple aspects of CKD, its trajectory, management and patient outcomes. Intent of the CKD.CRE is to facilitate an expanded Registry network that has representation from health services, both public and private, across Australia.

Although early diagnosis and improved treatment can reduce breast cancer mortality, there still appears to be a geographic differential in patient outcomes. This study aims to determine and quantify spatial inequalities in intended adjuvant (radio-, chemo- and hormonal) therapy usage among women with screen-detected breast cancer in Queensland, Australia. Linked population-based datasets from BreastScreen Queensland and the Queensland Cancer Registry during 1997-2008 for women aged 40-89 years were used. We adopted a Bayesian shared spatial component model to evaluate the relative intended use of each adjuvant therapy across 478 areas as well as common spatial patterns between treatments. Women living closer to a cancer treatment facility were more likely to intend to use adjuvant therapy. This was particularly marked for radiotherapy when travel time to the closest radiation facility was 4 + h (OR =0.41, 95 % CrI: [0.23, 0.74]) compared to Queensland. Moreover, the presence of residual shared spatial effects indicates that there are other unmeasured geographical barriers influencing women's treatment choices. This highlights the need to identify the additional barriers that impact on treatment intentions among women diagnosed with screen-detected breast cancer, particularly for those women living further away from cancer treatment centers.

Floral function: effects of traits on pollinators, male and female pollination success, and female fitness across three species of milkweeds (Asclepias).

Science.gov (United States)

La Rosa, Raffica J; Conner, Jeffrey K

2017-01-01

Central questions in plant reproductive ecology are whether the functions of floral traits in hermaphrodites create conflict between sexes that could slow evolution, and whether individual floral traits function in pollinator attraction, efficiency, or both. We studied how floral traits affect pollinator visitation and efficiency, and how they affect male and female function and female fitness within and across three Asclepias species that differ in floral morphology. Using separate multiple regressions, we regressed pollen removal, deposition, and fruit number onto six floral traits. We also used path analyses integrating these variables with pollinator visitation data for two of the species to further explore floral function and its effects on fruit production. Most traits affected male pollination success only, and these effects often differed between species. The exception was increased slit length, which increased pollinia insertion in two of the species. There were no interspecific differences in the effects of the traits on female pollination success. All traits except horn reach affected pollination efficiency in at least one species, and horn reach and two hood dimensions were the only traits to affect pollinator attraction, but in just one species. Traits tended to function in only one sex, and more traits affected function through pollinator efficiency than through attraction. There was no significant link between female pollination success and female fitness in any of the three species; this pattern is consistent with fruit production not being limited by pollen deposition. © 2017 Botanical Society of America.

2017-12-01

Among the numerous factors that contribute to young novice drivers' driving styles, personality characteristics, sociodemographic variables, family atmosphere, and friends' norms are known to have an important impact. However, cross-cultural comparisons are relatively rare in the safety literature concerning young drivers. This study aimed at comparing young drivers from Israel and Queensland (Australia) and examining the contribution of personality, sociodemographic, family and friends' aspects to their driving styles (reckless and careless; hostile and angry; anxious; patient and careful). More specifically, this study examined the associations between young drivers' driving style and their perceptions of separation-individuation, the family climate for road safety, and the safe driving climate among friends. We also examined sociodemographic and driving history variables such as gender, the marital status of parents, and personal exposure to traffic crashes. The study consisted of two samples of male and female young drivers (age 17-22) from Israel (n=160) and Queensland (n=160), who completed a set of valid and reliable self-report questionnaires. Findings indicate that in general, maladaptive driving styles are associated with lower family tendency to engage in promoting road safety, higher pressure and costs of driving with peers, and unhealthier separation-individuation aspects. The opposite is observed for the patient and careful driving style that relates to higher engagement of the family in road safety, lower pressure from friends, and healthier separation-individuation. Some differences were found regarding specific styles between the two samples. In addition, women scored lower than men in the reckless and careless style, and higher (in the Israeli sample) in the anxious as well as the patient and careful styles. Overall, similarities in the associations between the study variables in the samples exceed the differences, and the importance of examining

Laboratory leach tests have been carried out to compare the effectiveness of Caro's acid (permonosulphuric acid) as an alternative oxidant to pyrolusite in the leaching of uranium ores. Results demonstrated that Caro's acid reduced acid consumption in leaching and the time required for neutralisation of tailings liquor. The uranium extraction was unaffected by choice of oxidant. A plant trial confirmed that significant savings in acid and lime usage can be achieved under plant conditions. Plant operations also demonstrated that Caro's acid has a number of significant operating advantages over pyrolusite. Queensland Mines Ltd. have recently decided to convert their leaching process from pyrolusite to Caro's acid

Full Text Available Introduction: One of the basics of healthy eating is five times consumption of fruits and vegetable a day. Given the importance of recognizing effective factors of consuming fruit and vegetable in this group, the present study aimed to investigate high school girl's adherence to five-time serving fruits and vegetables per day in Hamadan based on the theory of planned behavior application. Materials and Methods: This descriptive-analytical study was performed on 400 girl students from high schools of Hamadan recruited with a multistage cluster sampling method. Participants filled out questionnaires including demographic variables, the theory of planned behavior constructs and a fruit and vegetable consumption measure one week later. Data analysis was performed using SPSS-18 by Chi-square, Pearson correlation and Logistic regression. Results: Fruit and vegetable consumption by female students is 3.4 times daily. Among the demographic variables, family size, mother's education, father's occupation, household income, body mass index and type of school had significant associations with fruit and vegetable consumption (P<0.05. Behavioral intention predicted 35% of the variation in daily fruit and vegetable consumption. Moreover, subjective norms, perceived behavioral control and attitude were able to predict 32% of behavioral intention. Conclusion: Fruit and vegetable consumption in female students is inadequate. The theory of planned behavior may be a useful framework to design a 5-A-Day intervention for female students.

Full Text Available Objective : To describe the demographic and clinical characteristics of patients hospitalized with pandemic A(H1N1 2009 infection in Queensland, Australia between 25 May and 3 October 2009 and to examine the relationship between timing of antiviral treatment and severity of illness.Method: Using data from the Queensland Health EpiLog information system, descriptive analysis and logistic regression modelling were used to describe and model factors which influence patient outcomes (death, admission to intensive care unit and/or special care unit. Data on patients admitted to hospital in Queensland with confirmed pandemic A(H1N1 2009 infection were included in this analysis.Results: 1236 patients with pandemic A(H1N1 2009 infection were admitted to hospitals in Queensland during the study period. Of the total group: 15% were admitted to an intensive care unit or special care unit; 3% died; 34% were under the age of 18 years and 8% were 65 years of age or older; and 55% had at least one underlying medical condition. Among the 842 patients for whom data were available regarding the use of antiviral drugs, antiviral treatment was initiated in 737 (87.5% patients with treatment commencing at a median of one day (range 1–33 days after onset of illness. Admission to an intensive care unit or special care unit (ICU/SCU or death was significantly associated with increased age, lack of timeliness of antiviral treatment, chronic renal disease and morbid obesity.Discussion: Early antiviral treatment was significantly associated with lower likelihood of ICU/SCU admission or death. Early antiviral treatment for influenza cases may therefore have important public health implications.

The objective of the present research was to determine if gamma radiations could be used as a quarentenary process against the orange fruit borer, Ecdytolopha aurantiana (Lima, 1927), infesting oranges of the variety 'Pera', beyond observations on some fruit quality parameters. To observe the gamma radiations effects on the insects, doses ranging from the control to 800 Gy were used, and to observe possible effects on fruits quality, the utilized doses ranges from the control to 500 Gy. To observe the gamma radiations effects on the insects, doses ranging from the control to 800 Gy were used, and to observe possible effects on fruits quality, the utilized doses ranged from the control to 500 Gy. It was observed that over 200 Gy avoid emergency of viable adults of the orange fruit borer. Only one single female, and even these with wing malformations, emerged at the dose of 300 Gy. Dose up to 500 Gy did not interfere on fruits weight loss nor on the period of conservation of the oranges. Acidity, Brix value and skin resistance against perforation also did not showed any changes due to radiations. The irradiation of green fruit induced into a smaller loss of weight than when the fruits were irradiated in the mature stage. (author)

Background: Higher intakes of fruits and vegetables, rich in micronutrients, have been associated with better mental health. However, cooking or processing may reduce the availability of these important micronutrients. This study investigated the differential associations between intake of raw fruits and vegetables, compared to processed (cooked or canned) fruits and vegetables, and mental health in young adults. Methods: In a cross-sectional survey design, 422 young adults ages 18–25 (66.1% female) living in New Zealand and the United States completed an online survey that assessed typical consumption of raw vs. cooked/canned/processed fruits and vegetables, negative and positive mental health (depressive symptoms, anxiety, negative mood, positive mood, life satisfaction, and flourishing), and covariates (including socio-economic status, body mass index, sleep, physical activity, smoking, and alcohol use). Results: Controlling for covariates, raw fruit and vegetable intake (FVI) predicted reduced depressive symptoms and higher positive mood, life satisfaction, and flourishing; processed FVI only predicted higher positive mood. The top 10 raw foods related to better mental health were carrots, bananas, apples, dark leafy greens like spinach, grapefruit, lettuce, citrus fruits, fresh berries, cucumber, and kiwifruit. Conclusions: Raw FVI, but not processed FVI, significantly predicted higher mental health outcomes when controlling for the covariates. Applications include recommending the consumption of raw fruits and vegetables to maximize mental health benefits. PMID:29692750

A group of 200 Queensland adults without known health problems had in-vivo estimation of finger bone lead concentrations using X-ray fluorescence analysis (XRF). Forty of these subjects had elevated levels of bone lead of 25 ppm or more, consistent with exposure to the metal. Although the correlation between Queensland residence during childhood and raised bone lead levels was not significant, there were significant correlations between childhood residence in a painted wooden house and raised levels, and between occupational exposure and raised levels. Of the 40 subjects with elevated lead levels only two had neither a history of occupational exposure or childhood residence in a wooden house, whereas 11 of the 25 who had a history of both occupational and residential exposure were positive. The data are consistent with lead in housepaint, or absorbed during occupational exposure, being the two major sources of raised bone lead concentrations. (author)

The primary aim of this study was to determine the prevalence of current strength-based exercise in rural and regional populations of Central Queensland. The secondary aim was to examine the proportion of residents from various demographic groups who currently partake in strength-based exercise to allow for targeted strength training campaigns. A cross-sectional, survey-based experimental design was followed. Rural and regional Australia. Rural and regional community-dwelling individuals living in Central Queensland and aged 18 years and older. Survey data was collected in October and November 2010 as part of the Central Queensland University Social Survey. Strength-based exercise participation, gender, age, income, years of education, self-reported physical activity and perception of health. Participation in strength-based exercise was 13.2%. Women were less likely to partake in strength-based exercise than male, and ≥55 year old adults were less likely to partake in strength-based exercise than 18-34 year old adults. Participation in strength-based exercise was found to increase with years of education, self-reported physical activity and self-rated health. The prevalence of adults in rural and regional Central Queensland engaging in strength-based exercise is low. Exercise physiologists, clinicians and government officials must work together to ensure that this form of exercise is acknowledged as a vital component of health in rural and regional areas. © 2015 National Rural Health Alliance Inc.

Little is known about the prevalence of refractive error, binocular vision, and other visual conditions in Australian Indigenous children. This is important given the association of these visual conditions with reduced reading performance in the wider population, which may also contribute to the suboptimal reading performance reported in this population. The aim of this study was to develop a visual profile of Queensland Indigenous children. Vision testing was performed on 595 primary schoolchildren in Queensland, Australia. Vision parameters measured included visual acuity, refractive error, color vision, nearpoint of convergence, horizontal heterophoria, fusional vergence range, accommodative facility, AC/A ratio, visual motor integration, and rapid automatized naming. Near heterophoria, nearpoint of convergence, and near fusional vergence range were used to classify convergence insufficiency (CI). Although refractive error (Indigenous, 10%; non-Indigenous, 16%; p = 0.04) and strabismus (Indigenous, 0%; non-Indigenous, 3%; p = 0.03) were significantly less common in Indigenous children, CI was twice as prevalent (Indigenous, 10%; non-Indigenous, 5%; p = 0.04). Reduced visual information processing skills were more common in Indigenous children (reduced visual motor integration [Indigenous, 28%; non-Indigenous, 16%; p < 0.01] and slower rapid automatized naming [Indigenous, 67%; non-Indigenous, 59%; p = 0.04]). The prevalence of visual impairment (reduced visual acuity) and color vision deficiency was similar between groups. Indigenous children have less refractive error and strabismus than their non-Indigenous peers. However, CI and reduced visual information processing skills were more common in this group. Given that vision screenings primarily target visual acuity assessment and strabismus detection, this is an important finding as many Indigenous children with CI and reduced visual information processing may be missed. Emphasis should be placed on identifying

Full Text Available The future need for sustainable agriculture will be met in part by wider use of biological control of plant pathogens over conventional fungicides hazardous to the environment and to public health. Control strategies involving both (i direct use of microorganisms antagonistic to the phytopathogen, and (ii use of bioactive compounds (secondary metabolites/antibiotic compounds from microorganisms on the phytopathogen were both adapted in order to investigate the ability of streptomycetes isolated from the rhizosphere of strawberry plants to promote the growth of the fruit and suppress Botrytis cinerea causing strawberry rot on the Sunshine Coast, Queensland, Australia. In vitro studies showed that 25/39 streptomycetes isolated from strawberry field soils inhibited B. cinerea growth by antifungal activity, ranging from antibiosis to volatile compound production. However, when non-volatile antifungal compounds were extracted and applied aerially to the actively growing strawberry fruits infected with B. cinerea, a significant disease reduction was not recorded. On the other hand, plant and fruit growth was promoted by the presence of actively growing streptomycetes in container media. Findings might indicate that live streptomycete inoculum can be used as growth promoting agent in container media for this economically important crop.

Steritech Pty Ltd operates the only three industrial gamma sterilisation and decontamination plants in Australia. A plant in Dandenong Victoria has operated since 1971 and a second in Wetherill Park from 1985. In August 2003, a third facility started commercial operation in Narangba, 40km north of Brisbane. Each plant represents a generational change in operating features, although the basic design of the irradiation room, storage pool and shielding remains substantially the same. This paper discusses some of the key design features of the Queensland plant, the complex approval and licensing process and some of the complications caused by perceived terrorist threats

Idesia polycarpa Maxim. is a promising plant for biodiesel in China. We have reported the flowering phenology, breeding system and parental effect on fruit characters of this species distributed in Qinling-Bashan Mountain (Shaanxi Province) nature reserve. As a dioecious plant, the male and female flowered almost synchronously. The anthesis was from around 10th of May and proceeded until the end of May or the beginning of June at population level. To determine the breeding system of I. polycarpa, three pollination treatments were carried out on every three female plants: natural pollination (NP), apomixy (AP) and cross pollination (CP). Reproductive success of apoximy treatment indicated that, as a dioecious plant, I. polycarpa could also reproduce by apomixis. However, the mean fruit set under apomixy treatment was markerly lower (3.6–13.33%) than that of two pollination treatments (>65.69%). Fruit quality (fruit length, fruit width, 100 fruit weight, seed production and seed germination) of the cross pollination treatment was greater than the other two treatments, suggested that pollen competition in cross pollination treatment was the most intense in three treatments. To study parental effect on fruit characters, cross pollination was carried out with three female plants and three male plants. The result showed that maternal parents (P<0.001) and parental interaction significantly affected all the fruit characters (including 100 fruit weight, pulp/fruit ratio, oil content and seed germination) while paternal parents showed significant effects on 100 fruit weight, pulp/fruit ratio and seed germination. Fruit set was only significantly affected by maternal parents (P=0.001). Our findings will facilitate future breeding programs of I. polycarpa in parental selection. (author)

Full Text Available Australia has a very high rate of dog ownership, which in some circumstances may lead to exposure to zoonotic parasitic diseases from those companion animals. Domestic dog faecal samples (n = 300 were collected from public spaces and private property in the greater Rockhampton (Central Queensland region and tested for intestinal helminths and protozoa by direct microscopy, two flotation methods and a modified acid-fast stain for cryptosporidia. Intestinal parasites detected included hookworms (25%, Cystoisospora ohioensis complex (9%, Blastocystis hominis (3%, Giardia duodenalis (3%, Spirometra erinacei (1% and Toxocara canis (1%, Sarcocystis spp. (2%, Cryptosporidium spp. (2% and Cystoisospora canis (1%. One infection each with Trichuris vulpis, Dipylidium caninum and a protozoa belonging to the Entamoeba histolytica complex were identified. Sheather’s sucrose centrifugal flotation was more sensitive than saturated salt passive flotation, but no single test detected all cases of parasitic infection identified. The test methodologies employed are poor at recovering larva of Strongyloides stercoralis, Aleurostrongylus abstrussis and eggs of cestodes such as Echinococcus granulosis, so the potential presence of these parasites in Central Queensland domestic dogs cannot be excluded by this survey alone.

Radiation in the treatment of high grade malignant gliomas in Queensland

Franklin, C.I.V.

1991-01-01

Two hundred and seventy eight patients with histologically proven grade 3 or grade 4 astrocytomas were referred to the Queensland Radium Institute for consideration of radiotherapy between January 1980 and December 1987. The role of radiation in the management of these tumours was examined with respect to the effects of field size, dose and age. It was found that field size did not have a significant effect on survival; in particular whole brain irradiation for patients with grade 4 tumours was not a significant advantage. The doses used at the Queensland Radium Institute produce similar survivals to those used in other centres. The effect of age was significant. For grade 3 tumours there was a survival advantage to those under 50 years receiving radiation, but not to those above that age. For grade 4 tumours, the survival advantage was for those under 60 years, but hose over 60 years did seem to get some benefit although the difference did not reach significance. It is suggested that, as the tumour is generally incurable, these patients may be better served by a short simple palliative course of radiation. 12 refs., 4 figs

Development of improved attractants and their integration into fruit fly SIT management programmes. Proceedings of a final research coordination meeting

International Nuclear Information System (INIS)

2007-10-01

Information provided by trapping systems is used to assess the presence, seasonal abundance, spatial distribution, host sequence and infestation levels of fruit fly pests. This information is key for implementation of effective fruit fly control programmes. Most trapping systems commercially available are based on para-pheromones which are male specific. These male specific trapping systems have been used as the main survey tool in area-wide fruit fly control programmes. Nevertheless, in recent years, scientists and programme managers have realized that, in order to improve the efficiency of fruit fly control, it is essential to have a female specific or at least a female biased trapping system. Until the late 1990s, the only fruit fly female biased attractants were based on natural protein baits such as Torula Yeast and hydrolysate proteins. Although these attractants tend to catch more females than males (in average 60% females against 40% males), the proportion in favor of females is insufficient and the attractants are considered to be weak and non-selective. In 1999, as a result of a previous Coordinated Research Project (CRP) entitled 'Development of Female Medfly Attractant Systems for Trapping and Sterility Assessment' the first effective female biased synthetic food lure was developed for the Mediterranean fruit fly (Ceratitis capitata, Wied.) (IAEA-TECDOC-1099). This lure, with the commercial name of Biolure, is now being used in large-scale medfly control programmes worldwide. Given this background, and in order to further advance this field, the Joint FAO/IAEA Programme approved in 2000 a five year CRP entitled 'Development of Improved Attractants and their Integration into Fruit Fly SIT Management Programmes'. The research conducted under this CRP focused mainly on developing female biased trapping systems for other fruit fly species of quarantine and economic importance within the Anastrepha, Bactrocera, Ceratitis and Dacus genera and on optimization

This retrospective population-based study examined drowning location by the site of immersion for both fatal and non-fatal drowning events in Queensland. Drowning location is not routinely collected, and this study used data linkage to identify drowning sites. The resulting enhanced quality data quantify drowning incidence for specific locations by geographic region, age group and by severity for the first time. Linked data were accessed from the continuum of care (prehospital, emergency, hospital admission and death data) on fatal and non-fatal drowning episodes in children aged 0-19 years in Queensland for the years 2002-2008 inclusive. Drowning locations ranked in order of overall incidence were pools, inland water, coastal water, baths and other man-made water hazards. Swimming pools produced the highest incidence rates (7.31/100,000) for overall drowning events and were more often privately owned pools and in affluent neighbourhoods. Toddlers 0-4 years were most at risk around pools (23.94/100,000), and static water bodies such as dams and buckets-the fatality ratios were highest at these 2 locations for this age group. Children 5-14 years incurred the lowest incidence rates regardless of drowning location. Adolescents 15-19 years were more frequently involved in a drowning incident on the coast shoreline, followed by inland dynamic water bodies. Linked data have resulted in the most comprehensive data collection on drowning location and severity to date for children in the state of Queensland. Most mortality and morbidity could have been prevented by improving water safety through engaged supervision around pools and bath time, and a heightened awareness of buckets and man-made water hazards around the farm home for young children. These data provide a different approach to inform prevention strategies. Published by the BMJ Publishing Group Limited.

Full Text Available Our study aimed to assess the impact of a six-months nutrition program, taught by trained teachers, on fruit and vegetable consumption among children in grades 1 to 4. Four hundred and sixty-four children (239 female, 6 to 12 years old, from seven elementary schools were assigned to this randomized trial. Teachers were trained by researchers over six months, according to the following topics: nutrition, healthy eating, and strategies to increase physical activity. After each session, teachers were encouraged to develop activities in the classroom on the topics learned. Children's sociodemographic, anthropometric, dietary, and physical activity data were assessed at baseline and at the end of the intervention. The effect sizes ranged between small (Cohen's d=0.12 on “other vegetables” to medium (0.56 on “fruit and vegetable”, and intervened children reported a significantly higher consumption of vegetables and fruit. Interventions involving trained teachers offer promise to increase consumption of fruit and vegetable in children.

Understanding shark habitat use is vital for informing better ecological management of coastal areas and shark populations. The Queensland Shark Control Program (QSCP) operates over ∼1800 km of Queensland coastline. Between 1996 and 2012, catch, total length and sex were recorded from most of the 1992 bull shark (Carcharhinus leucas) caught on drum lines and gill-nets as part of the QSCP (sex and length was not successfully recorded for all individuals). Gear was set at multiple sites within ten locations. Analysis of monthly catch data resulted in a zero-inflated dataset for the 17 years of records. Five models were trialled for suitability of standardising the bull shark catch per unit effort (CPUE) using available habitat and environmental data. Three separate models for presence-absence and presence-only were run and outputs combined using a delta-lognormal framework for generalized linear and generalized additive models. The delta-lognormal generalized linear model approach resulted in best fit to explain patterns in CPUE. Greater CPUE occurred on drum lines, and greater numbers of bull sharks were caught on both gear types in summer months, with tropical sites, and sites with greater adjacent wetland habitats catching consistently more bull sharks compared to sub-tropical sites. The CPUE data did not support a hypothesis of population decline indicative of coastal overfishing. However, the total length of sharks declined slightly through time for those caught in the tropics; subtropical catches were dominated by females and a large proportion of all bull sharks caught were smaller than the size-at-maturity reported for this species. These factors suggest that growth and sex overfishing of Queensland bull shark populations may be occurring but are not yet detectable in the available data. The data highlight available coastal wetlands, river size, length of coastline and distance to the 50 m depth contour are important for consideration in future whole of

Roles of semiochemicals in mating systems: A comparison between Oriental fruit fly and Medfly

Nishida, Ritsuo; Shelly, Todd E.; Kaneshiro, Kenneth Y.; Tan, Keng-Hong

2000-01-01

Males of tephritid fruit fly species show strong affinity to specific chemicals produced by plants. Amongst the economically important species in the Asian Pacific area, methyl eugenol acts as a potent attractant for males of the Oriental fruit fly, Bactrocera dorsalis (Hendel), and several other species within the dorsalis species complex (e.g., B. papayae Drew and Hancock, B. carambolae Drew and Hancock, etc.), cuelure [4-(4-acetoxyphenyl)-2-butanone] and the naturally occurring deacetyl derivative (raspberry ketone) act as specific attractants for flies such as the melon fly, B. cucurbitae (Coquillett) and the Queensland fruit fly, B. tryoni (Froggatt) (Metcalf 1990). These attractants have been successfully used as baits in mass trapping for monitoring populations during eradication programmes for these pests (Chambers 1977, Koyama et al. 1984). Likewise, trimedlure has been developed as a synthetic attractant for males of the Mediterranean fruit fly (Medfly), Ceratitis capitata (Wied.), while α-copaene has been known to be a naturally occurring attractant for the species. For most tephritids, however, the biological function of male attraction to these natural or artificial compounds remains unclear. Recent studies (Nishida et al. 1988 1997, Nishida and Fukami 1990, Tan 1993, Tan and Nishida 1996) have shown that males of B. dorsalis and related species ingest these compounds from natural sources, selectively incorporate them into the rectal glands, and use them to synthesise the sex pheromone and allomone. It appears that similar chemical compounds, when ingested, may provide pheromonal precursors in the melon fly as well (Nishida et al. 1993, Shelly and Villalobos 1995). In contrast, Medfly males do not feed on the source of chemical attractant. According to our observations, α-copaene strongly affected the courtship behaviour of the Medfly, which suggests that these natural compounds may possibly be involved in the formation of leks and the mating

Host range and reproductive output of Diachasmimorpha kraussii (Hymenoptera: Braconidae), a parasitoid of tephritid fruit flies newly imported to Hawaii

Messing, R.H.; Ramadan, M.M.

2000-01-01

Four exotic tephritid fruit fly pests have colonised the Hawaiian islands over the past 100 years, where they have become major pests infesting hundreds of horticultural crops. The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), Oriental fruit fly, Bactrocera dorsalis (Hendel), melon fly, B. cucurbitae (Coquillett), and Solanaceous fruit fly, B. latifrons (Hendel) are considered among the major obstacles to the development of a more robust agricultural economy in the state of Hawaii. Furthermore, the flies pose a continuous threat to agriculture in California and other areas in the southern United States, where it has been estimated that the establishment of the Medfly alone would result in losses of over one billion dollars annually (Andrew et al. 1978). Entomologists in Hawaii have conducted a number of classical biological control programmes against these tephritid pests over the years, resulting in the establishment of several parasitoid species and partial control of the flies in some crops (see reviews in Clausen et al. 1965, Wharton 1989). However, these programmes were conducted before the invasion of the state by the Solanaceous fruit fly; thus, there have been no biocontrol programmes targeted against this pest. Also, several entomologists have pointed out the potential of improved control over the other tephritid species in Hawaii by introducing new natural enemies (Gilstrap and Hart 1987, Messing 1995, Steck et al. 1986, Wharton 1989, Wong and Ramadan 1992). We have therefore renewed efforts to import parasitoids from tropical and sub-tropical areas around the world to attack tephritid fruit flies in Hawaii. As part of this effort, we imported Diachasmimorpha kraussii Fullaway from Queensland, Australia, where it is an endemic parasitoid of Bactrocera tryoni (Froggatt) and several other endemic Australian tephritids. This paper reports the results of initial host range tests and studies on the reproductive output of D. kraussii in quarantine

Three new species are described in the genus Drymopsalta Ewart, previously known only from D. crepitum Ewart and D. daemeli Distant. The three new species occur in Southern Queensland and Northern Territory. D. wallumi sp. nov. occurs along coastal S.E. Queensland, whereas D. hobsoni sp. nov. is restricted to the Bringalily State Forest, near Inglewood, southern inland Queensland. D. acrotela sp. nov. is found in the Litchfield National Park and other locations near Jabaluka, Cahills Crossing, E. Alligator River and Nourlangie, all across the northern Northern Territory. D. crepitum occurs on the Cape York Peninsular extending into the southern Gulf, while D. daemeli occurs in two localised regions in central coastal N.S.W. Each of the species inhabits heath vegetation, often spilling-over into adjacent tree foliage. The species of Drymopsalta are small and inconspicuous cicadas (cicadas. Two additional song variants are described, a more unstructured chirping song without intervening single ticks observed in each of the species except D. crepitum, and periodic extended buzzing echemes emitted within the calling songs (excepting the D. wallumi song).

To quantify the population attributable risk of key modifiable risk factors associated with breast cancer incidence in Queensland, Australia. Population attributable fractions (PAFs) for high body mass index (BMI), use of hormone replacement therapy (HRT), alcohol consumption and inadequate physical activity were calculated, using prevalence data from a representative survey of women attending mammographic screening at BreastScreen Queensland in 2008 and relative risk estimates sourced from published literature. Attributable cancers were calculated using 'underlying' breast cancer incidence data for 2008 based on Poisson regression models, adjusting for the inflation of incidence due to the effects of mammographic screening. Attributable burden of breast cancer due to high body mass index (BMI), use of hormone replacement therapy (HRT), alcohol consumption and inadequate physical activity. In Queensland women aged 45-69 years, an estimated 12.1% (95% CI: 11.6-12.5%) of invasive breast cancers were attributable to high BMI in post-menopausal women who have never used HRT; 2.8% (95% CI: 2.7-2.9%) to alcohol consumption; 7.6% (95% CI: 7.4-7.9%) to inadequate physical activity in post-menopausal women and 6.2% (95% CI: 5.5-7.0%) to current use of HRT after stratification by BMI and type of HRT used. Combined, just over one quarter (26.0%; 95% CI: 25.4-26.6%) of all invasive breast cancers in Queensland women aged 45-69 years in 2008 were attributable to these modifiable risk factors. There is benefit in targeting prevention strategies to modify lifestyle behaviours around BMI, physical activity, HRT use and alcohol consumption, as a reduction in these risk factors could decrease invasive breast cancer incidence in the Queensland population.

2014-08-01

Hypoxic ischaemic encephalopathy (HIE) is secondary to intrapartum asphyxia and the fifth largest cause of death of children under five. Incorrect use and interpretation of intrapartum cardiotocographs has been identified as a contributing factor to the development of HIE. Therefore, RANZCOG introduced the Fetal Surveillance Education Program (FSEP) to improve education and practice of intrapartum care. To investigate the incidence of HIE throughout Queensland between 2003 and 2011 during the introduction and implementation of RANZCOG FSEP. The incidence of HIE admissions at each hospital in Queensland (2003-2011) was collated from Queensland Health Statistics Centre. RANZCOG FSEP provided data regarding course attendees throughout Queensland (2006-2011). Hospitals were grouped into four regions. Statistical analysis was conducted using Stata(TM) (version 12.0) - data appeared to follow a damped harmonic model. The posteducation (2006-2011) HIE rate was significantly lower (P = 0.02) than the pre-education (2003-2005) rate. The final model predicted a stabilisation of HIE occurrence rate at approximately 160 events/100,000 live births by 2012. This rate was stable if the level of education was maintained but rose back to the initial rate of 250 events/100,000 live births if the education participation was discontinued. This study identified a significant reduction in the incidence of HIE--a potentially life-threatening newborn condition--between 2003 and 2011, during and following FSEP implementation. Notwithstanding the inevitable limitations of state-based data collection, these results are encouraging. For such improvements to be sustained, education must reach all staff engaged in intrapartum care and be regularly repeated. © 2014 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

A review of necrophagous insects colonising human and animal cadavers in south-east Queensland, Australia.

Farrell, Julianne F; Whittington, Andrew E; Zalucki, Myron P

2015-12-01

A review of insects collected from decomposing human remains in south-east Queensland yielded 32 species in three orders (Diptera, Coleoptera, Hymenoptera) and 11 families (Calliphoridae, Sarcophagidae, Muscidae, Phoridae, Sepsidae, Chironomidae, Dermestidae, Cleridae, Histeridae, Staphylinidae, Encyrtidae). There were 15 cases where remains were located indoors and five cases where remains were outdoors, in both terrestrial and aquatic environments. Coleoptera were strongly associated with outdoors remains, while dipteran species composition was similar in both indoor and outdoor habitats. Some Diptera were only associated with indoors remains, while others were similarly restricted to remains recovered outdoors. Hymenopteran parasitoids were active in both habitats. Comparative collections were made from other vertebrate remains, including road-kill and farmed animals throughout south-east Queensland (Qld) and northern New South Wales (NSW) during the same period.

To describe the epidemiology and rates of all health care-associated bloodstream infections (HA-BSIs) and of specific HA-BSI subsets in public hospitals in Queensland. Standardised HA-BSI surveillance data were collected in 23 Queensland public hospitals, 2008-2012. HA-BSIs were prospectively classified in terms of place of acquisition (inpatient, non-inpatient); focus of infection (intravascular catheter-associated, organ site focus, neutropenic sepsis, or unknown focus); and causative organisms. Inpatient HA-BSI rates (per 10,000 patient-days) were calculated. There were 8092 HA-BSIs and 9418 causative organisms reported. Inpatient HA-BSIs accounted for 79% of all cases. The focus of infection in 2792 cases (35%) was an organ site, intravascular catheters in 2755 (34%; including 2240 central line catheters), neutropenic sepsis in 1063 (13%), and unknown in 1482 (18%). Five per cent (117 of 2240) of central line-associated BSIs (CLABSIs) were attributable to intensive care units (ICUs). Eight groups of organisms provided 79% of causative agents: coagulase-negative staphylococci (18%), Staphylococcus aureus (15%), Escherichia coli (11%), Pseudomonas species (9%), Klebsiella pneumoniae/oxytoca (8%), Enterococcus species (7%), Enterobacter species (6%), and Candida species (5%). The overall inpatient HA-BSI rate was 6.0 per 10,000 patient-days. The rates for important BSI subsets included: intravascular catheter-associated BSIs, 1.9 per 10,000 patient-days; S. aureus BSIs, 1.0 per 10,000 patient-days; and methicillin-resistant S. aureus BSIs, 0.3 per 10,000 patient-days. The rate of HA-BSIs in Queensland public hospitals is lower than reported by similar studies elsewhere. About one-third of HA-BSIs are attributable to intravascular catheters, predominantly central venous lines, but the vast majority of CLABSIs are contracted outside ICUs. Different sources of HA-BSIs require different prevention strategies.

To investigate opinions and concerns of Gold Coast residents regarding fluoridation of community water supplies. Anonymous data were collected in four major shopping centers from approximately 500 Gold Coast residents. Eighty-one percent of participants were aware of the addition of fluoride to the water supply. More than half obtained information on water fluoridation through the print and electronic media. Sixty percent of respondents supported water fluoridation. The majority preferred the public and/or health professionals to have made the decision on water fluoridation rather than the government. The percentage of residents supporting water fluoridation was lower than that found in other Queensland, Australian, and worldwide surveys. In this study, only age and the highest level of education attained were factors significantly related to levels of support for water fluoridation. The Queensland Government's decision to implement water fluoridation without a referendum caused disquiet amongst some Gold Coast residents. Future public health initiatives therefore may be assisted by more consultation with, and involvement from, health professionals in the relevant fields. Public health campaigns may benefit more from interaction with the community in order to address their specific concerns. © 2012 Wiley Publishing Asia Pty Ltd.

Most of what is currently known about western gorilla (Gorilla gorilla) diet is based on indirect studies using fecal samples and trail signs rather than measures based on direct observations. Here we report results on adult male and female western gorilla foraging behavior, based on systematic focal observations and nutritional analyses of foods. We found that western gorillas, like other apes, are highly selective ripe fruit specialists, seeking fruit high in energy, low in antifeedants, and rare in the environment. During seasonal fruiting peaks, fruit accounted for up to 70% of feeding time. When ripe fruit was scarce, gorillas increased time spent feeding on leaves and nonpreferred fruits and herbs. Leaves were the major fallback food, accounting for up to 70% of feeding time in males and 50% in females during periods of fruit scarcity. In spite of large differences in body size, the sexes were remarkably similar in their overall diet, not differing in time spent feeding on fruit or preferred herbs. However, the male consistently fed more often and on a greater variety of leaves than did females, whereas females fed more often on fallback herbs and termites. Our findings, when considered in light of previous findings on sympatric mangabeys, indicate that the foraging strategy of western gorillas is broadly similar to that of chimpanzees and orangutans, and distinct from that of old world monkeys.

Full Text Available Rehabilitation of marine turtles in Queensland has multifaceted objectives. It treats individual animals, serves to educate the public, and contributes to conservation. We examined the outcome from rehabilitation, time in rehabilitation, and subsequent recapture and restranding rates of stranded marine turtles between 1996 and 2013 to determine if the benefits associated with this practice are cost-effective as a conservation tool. Of 13,854 marine turtles reported as stranded during this 18-year period, 5,022 of these turtles were stranded alive with the remainder verified as dead or of unknown condition.

A tale of two telescopes: North Queensland and the 1882 transit of Venus

Science.gov (United States)

Orchiston, Wayne; Darlington, Vicki

2017-08-01

The 1882 transit of Venus offered the final opportunity for astronomers to use these rare events to pin down the distance from the Earth to the Sun. A British party based itself in southern Queensland, but total cloud cover prevented any observations being made on the critical day. In this paper we trace the preparations of the British party, and then show how they laid the foundations for the development of astronomy in Queensland by selling their two 6-in Cooke refractors before returning to Britain. Both instruments were purchased by a Townsville amateur astronomer, Edwin Norris, and although he installed one in an observatory, he made little use of it. However, he subsequently sold the other telescope to J. Ewen Davidson of Mackay, who also erected an obser-vatory for it. Davidson then used his instrument for cometary astronomy, in the process discovering two new comets, one of which now bears his name. Unfortunately, recent attempts to track down the present whereabouts of the two telescopes have failed.

The study was undertaken to determine the influence of pollen sources and pollination frequency on fruit drop, yield and quality of date palm cv. 'Dhakki'. Three 'Dhakki' female trees and three different male trees (M-1, M-2 and M-3) were selected for the experiment. On each female tree six spathes were chosen and were pollinated with pollens collected from one of the selected male parent. Out of six, three spathes were pollinated once and other three were pollinated twice (second pollination was done two days after first pollination). Data were collected for physico-chemical characteristics of the fruit including fruit drop, fruit weight, flesh weight, seed weight, total soluble solids (TSS), titratable acidity (TA), TSS: TA ratio, sugars, level of ascorbic acid and total phenols. The results indicated that pollen source significantly affected the fruit drop percentage as minimum fruit drop was observed from the tree pollinated with M-3. Physical properties of the fruit like fruit weight, flesh weight and seed weight were significantly improved with pollination from M-1 compared to other male trees. After harvest chemical quality parameters like TSS and TSS: TA ratio, ascorbic acid contents, and reducing sugars were highest in fruit pollinated with M-3 and M-2 respectively. Whereas lowest level of TA was recorded in fruits pollinated with M-3. Pollen source and number of pollinations did not significantly affect the level of total phenols in the date palm fruit. Total and non-reducing sugars were significantly higher in the fruit pollinated twice. In conclusion, the pollen source had significant impact on the physicochemical properties of date palm cv. 'Dhakki'. The results suggested that best pollen source (male trees) should be selected for their respective female trees to get most desired characteristics. (author)

Ethylene is a key factor regulating sex expression in cucurbits. Commercial melons (Cucumis melo L.) are typically andromonoecious, producing male and bisexual flowers. Our prior greenhouse studies of transgenic melon plants expressing the dominant negative ethylene perception mutant gene, etr1-1, under control of the carpel- and nectary-primordia targeted CRAB'S CLAW (CRC) promoter showed increased number and earlier appearance of carpel-bearing flowers. To further investigate this phenomenon which could be potentially useful for earlier fruit production, we observed CRC::etr1-1 plants in the field for sex expression, fruit set, fruit development, and ripening. CRC::etr1-1 melon plants showed increased number of carpel-bearing open flowers on the main stem and earlier onset by 7-10 nodes. Additional phenotypes observed in the greenhouse and field were conversion of approximately 50% of bisexual buds to female, and elongated ovaries and fruits. Earlier and greater fruit set occurred on the transgenic plants. However, CRC::etr1-1 plants had greater abscission of young fruit, and smaller fruit, so that final yield (kg/plot) was equivalent to wild type. Earlier fruit set in line M5 was accompanied by earlier appearance of ripe fruit. Fruit from line M15 frequently did not exhibit external ripening processes of rind color change and abscission, but when cut open, the majority showed a ripe or overripe interior accompanied by elevated internal ethylene. The non-ripening external phenotype in M15 fruit corresponded with elevated etr1-1 transgene expression in the exocarp. These results provide insight into the role of ethylene perception in carpel-bearing flower production, fruit set, and ripening.

An overview of quarantine for fruit flies

International Nuclear Information System (INIS)

Frampton, E.R.

2000-01-01

What is meant by 'quarantine for fruit flies'? The Collins dictionary describes 'quarantine' as a period of isolation or detention, especially of persons or animals arriving from abroad, to prevent the spread of disease. In providing an overview of quarantine for fruit flies, a broader definition needs to be applied, that is, the combination of activities required to maintain the fruit fly status of a particular geographical area - perhaps better referred to as a 'quarantine system'. Familiarity with New Zealand's quarantine system for fruit flies (Diptera: Tephritidae) provides a useful basis for subsequent comparison with other countries' systems where some fruit fly species may be present. But, why have 'quarantine for fruit flies'? The multivoltine life history of many species. combined with a relatively long-lived adult stage and highly fecund females, results in a high potential for rapid population increase (Bateman 1979, Fletcher 1987). These factors and the close association of fruit flies with harvested fruit or vegetables explain the high quarantine profile of these insects. However, there is no international requirement for a country to have a quarantine system and unless there are natural quarantine barriers (e.g., mountain range, oceans, deserts) that can be utilised, effective quarantine by an individual country may be an impossible task. The implementation of a successful quarantine system is very expensive and therefore, it would be expected that any benefits attained outweigh the costs (Ivess 1998). Ivess (1998) listed the following benefits from the implementation of an effective quarantine system: minimising production costs (including post harvest treatments), maintaining competitive advantages for market access due to the ongoing freedom from particular pests of quarantine significance, an environment free from many pests harmful to plant health, the maintenance of ecosystems

Feeding on ripening and over-ripening fruit: interactions between sugar, ethanol and polyphenol contents in a tropical butterfly.

Beaulieu, Michaël; Franke, Kristin; Fischer, Klaus

In ripe fruit, energy mostly derives from sugar, while in over-ripe fruit, it also comes from ethanol. Such ripeness differences may alter the fitness benefits associated with frugivory if animals are unable to degrade ethanol when consuming over-ripe fruit. In the tropical butterfly Bicyclus anynana , we found that females consuming isocaloric solutions mimicking ripe (20% sucrose) and over-ripe fruit (10% sucrose, 7% ethanol) of the palm Astrocaryum standleyanum exhibited higher fecundity than females consuming a solution mimicking unripe fruit (10% sucrose). Moreover, relative to butterflies consuming a solution mimicking unripe fruit, survival was enhanced when butterflies consumed a solution mimicking either ripe fruit supplemented with polyphenols (fruit antioxidant compounds) or over-ripe fruit devoid of polyphenols. This suggests that (1) butterflies have evolved tolerance mechanisms to derive the same reproductive benefits from ethanol and sugar, and (2) polyphenols may regulate the allocation of sugar and ethanol to maintenance mechanisms. However, variation in fitness owing to the composition of feeding solutions was not paralleled by corresponding physiological changes (alcohol dehydrogenase activity, oxidative status) in butterflies. The fitness proxies and physiological parameters that we measured therefore appear to reflect distinct biological pathways. Overall, our results highlight that the energy content of fruit primarily affects the fecundity of B. anynana butterflies, while the effects of fruit consumption on survival are more complex and vary depending on ripening stage and polyphenol presence. The actual underlying physiological mechanisms linking fruit ripeness and fitness components remain to be clarified. © 2017. Published by The Company of Biologists Ltd.

Demography and natural history of the common fruit bat, Artibeus jamaicensis, on Barro Colorado Island, Panama

carry it to a feeding roost typically about 100 m away before eating it. We utilized radio telemetry to assess feeding rates from the number of ?feeding passes??transits between fruit tree and feeding roost. Bats are often netted while carrying fruit, revealing their diet. Feces also reveal dietary information. Adult female A. jamaicensis live in harems of three to 30 individuals with a single adult male. On BCI the harem groups roost during the day in hollow trees. There is presumably a large population of surplus males that roost together with nonadults of both sexes in foliage. Females commute an average of 600 m from their day roosts to feeding sites, and harem males travel less than 300 m. Twice a year most females give birth to a single young, once in March or April, and again in July or August; active gestation averages about 19 weeks. Juveniles are first netted when they are about ten weeks old, and females usually first bear young in March or April following their year of birth.

Physical activity trends in Queensland (2002 to 2008): are women becoming more active than men?

Regular monitoring of population levels of physical activity is an effective way to assess change over time towards meeting public health recommendations. The objective of this study was to determine physical activity trends in Central Queensland over the period 2002 to 2008. Data was obtained from the Central Queensland Social Survey (CQSS) conducted annually from 2002 to 2008. A total sample of 8,936 adults aged 18 and over participated in seven cross-sectional surveys. Physical activity was measured using the Active Australia Questionnaire. Binary logistic regression was used to examine trends in sufficient physical activity. Averaged over all survey years 46.5% of study participants met national physical activity guidelines. A small significant upward trend was found for meeting physical activity recommendations across all years (OR=1.03; 95%CI=1.01-1.05), indicating that the odds of meeting the guidelines increased by an average of 3% per year from 2002 to 2008. Slightly more men than women met the activity guidelines (ns); however a significant positive trend in achieving sufficient activity levels was present in women only (4%). Although an increasing trend for sufficient physical activity was observed, overall physical activity levels in Central Queensland remain suboptimal and more efforts to increase physical activity are needed. The gender differences in physical activity trends indicate that men and women might need to be targeted differently in health promotion messages. The continuous monitoring of population levels of physical activity in Australia, which allow both state specific and international comparisons, is needed.

Radiocarbon and thermoluminescence dating of quaternary sediments in Deception Bay, southeast Queensland: some problems encountered

International Nuclear Information System (INIS)

Cotter, M.M.

1999-01-01

Full text: Radiocarbon and Thermoluminescence dating of sediment facies were utilised to develop a chronometric framework for the quaternary coastal evolution of Deception Bay southeast Queensland (Cotter 1996). This chronometric framework was developed in the context of a broader geoarchaeological and palaeogeographical investigation of the indigenous cultural landscape of the area. The TL analysis confirmed the presence of previously undated Pleistocene sands within the study area. However in the course of dating one sedimentary sequence, conventional radiocarbon analysis of Notispisula sheldls produced an age of 5190± 90 years BP (Beta-85415) whilst an overlying sandy unit (shown by particle size analysis and SEM surface textural analysis to be aeolian transported) subject to TL-dating produced an age of 14,900 ± 3300 years BP (W1942). This poster highlights the considerations made in order to reconcile this obvious anomaly. In effect, previously obtained radiometric data within the study area (Flood 1981; Hall 1996), in conjunction with an examination of the adequacy of the sampled materials for radiocarbon and TL age determinations point to the TL determination being in error. Similar anomalies have been shown to occur elsewhere in southeast Queensland (Tejan-Kella et al. 1990) explanations for which have been related to selective rather than total bleaching of Holocene sands (Prescott personal communication). Re-dating of the sand sequence using the selective bleach method is required to examine whether the dating anomaly shown for Deception Bay parallels selective bleaching effects determined for other sequences within southeast Queensland. Unfortunately this is beyond the scope and funds of this geoarchaeological study

Little is reported about the nutrition-related needs and preferences of women seeking maternity services, particularly Maori and Pasifika (M&P) women who have higher chronic disease rates in Queensland. Nutrition-related knowledge, needs, behaviours and education preferences were compared between women of M&P ancestry and non-Maori and Pasifika women (NMP). Women (≥18 years) admitted to the postnatal ward were surveyed. Anthropometry, dietary quality, nutrition education preferences, country of birth and ancestry were collected. Analysis included chi-squared and t-tests. The survey was completed by 399 eligible women. Country of birth data suggested 4% of respondents were Pasifika and failed to separately identify New Zealand Maori, whereas 18% of respondents (n=73) reported M&P ancestry. Descriptors were similar between groups (28±5 years; 91% any breastfeeding; 18% gestational diabetes mellitus; p>0.05). However M&P women were less often university educated (M&P:6(9%); NMP:71(22%), p2 children (M&P: 30(54%); NMP:70(30%), p75%) women did not know their recommended weight gain. Many respondents reported inadequate intake of vegetables (95%), fruit (29%) and dairy (69%) during pregnancy. Two-fifths (38-41%) reported interest in perinatal nutrition education, with topics including healthy eating postpartum. Findings enable targeted service delivery according to women's preferences. Collecting ancestral and maternal data to facilitate the provision of appropriate nutrition education may be critical for achieving optimal maternal outcomes in Maori and Pasifika women.

Classroom teachers located in Queensland, Australia are exposed to high levels of ambient solar ultraviolet as part of the occupational requirement to provide supervision of children during lunch and break times. We investigated the relationship between periods of outdoor occupational radiant exposure and available ambient solar radiation across different teaching classifications and schools relative to the daily occupational solar ultraviolet radiation (HICNIRP) protection standard of 30J/m(2). Self-reported daily sun exposure habits (n=480) and personal radiant exposures were monitored using calibrated polysulphone dosimeters (n=474) in 57 teaching staff from 6 different schools located in tropical north and southern Queensland. Daily radiant exposure patterns among teaching groups were compared to the ambient UV-Index. Personal sun exposures were stratified among teaching classifications, school location, school ownership (government vs non-government), and type (primary vs secondary). Median daily radiant exposures were 15J/m(2) and 5J/m(2)HICNIRP for schools located in northern and southern Queensland respectively. Of the 474 analyzed dosimeter-days, 23.0% were found to exceed the solar radiation protection standard, with the highest prevalence found among physical education teachers (57.4% dosimeter-days), followed by teacher aides (22.6% dosimeter-days) and classroom teachers (18.1% dosimeter-days). In Queensland, peak outdoor exposure times of teaching staff correspond with periods of extreme UV-Index. The daily occupational HICNIRP radiant exposure standard was exceeded in all schools and in all teaching classifications. Copyright © 2016 Elsevier B.V. All rights reserved.

The relationship between climate change and the endangered rainforest shrub Triunia robusta (Proteaceae) endemic to southeast Queensland, Australia

Shimizu-Kimura, Yoko; Accad, Arnon; Shapcott, Alison

2017-04-01

Threatened species in rainforests may be vulnerable to climate change, because of their potentially narrow thermal tolerances, small population sizes and restricted distributions. This study modelled climate induced changes on the habitat distribution of the endangered rainforest plant Triunia robusta, endemic to southeast Queensland, Australia. Species distribution models were developed for eastern Australia at 250 m grids and southeast Queensland at 25 m grids using ground-truthed presence records and environmental predictor data. The species’ habitat distribution under the current climate was modelled, and the future potential habitat distributions were projected for the epochs 2030, 2050 and 2070. The eastern Australia model identified several spatially disjunct, broad habitat areas of coastal eastern Australia consistent with the current distribution of rainforests, and projected a southward and upslope contraction driven mainly by average temperatures exceeding current range limits. The southeast Queensland models suggest a dramatic upslope contraction toward locations where the majority of known populations are found. Populations located in the Sunshine Coast hinterland, consistent with past rainforest refugia, are likely to persist long-term. Upgrading the level of protection for less formal nature reserves containing viable populations is a high priority to better protect refugial T. robusta populations with respect to climate change.

2010-01-01

This study aims to examine the impact of socio-ecologic factors on the transmission of Ross River virus (RRV) infection and to identify areas prone to social and ecologic-driven epidemics in Queensland, Australia. We used a Bayesian spatiotemporal conditional autoregressive model to quantify the relationship between monthly variation of RRV incidence and socio-ecologic factors and to determine spatiotemporal patterns. Our results show that the average increase in monthly RRV incidence was 2.4% (95% credible interval (CrI): 0.1–4.5%) and 2.0% (95% CrI: 1.6–2.3%) for a 1°C increase in monthly average maximum temperature and a 10 mm increase in monthly average rainfall, respectively. A significant spatiotemporal variation and interactive effect between temperature and rainfall on RRV incidence were found. No association between Socio-economic Index for Areas (SEIFA) and RRV was observed. The transmission of RRV in Queensland, Australia appeared to be primarily driven by ecologic variables rather than social factors. PMID:20810846

This study aims to ascertain if differences exist in the perception of the professional practice environment and personal well-being of nurses across different geographical areas in Queensland. This paper was performed on a prospective, self-report cross-sectional on-line survey. The study was conducted among the nurses employed in public and private health care settings: acute hospitals, community health and aged care in Queensland, Australia. Participants of this study were 1608 registered and enrolled nurses and assistants in nursing, current members of the Queensland Nurses Union in 2013 and who provided a workplace postcode. One thousand eight of these participants worked in major cities, while 382 in rural locations and 238 in remote areas. None. Scores of well-being as determined by the following scales: the Depression, Anxiety and Stress Scale, the Professional Quality of Life Scale version 5, the Connor-Davidson Resilience Scale and of the Professional Practice Environment using the Practice Environment Scale - Nursing Work Index Revised. Nurses employed in major cities perceived 'nursing foundations for quality care' more favourably than those from other settings. Remote area nurses had lower levels of secondary traumatic stress than nurses in major cities and rural areas. There was no difference between nurses across their geographical locations for stress, anxiety, depression, compassion satisfaction, burnout, resilience and the four other measures of the Practice Environment Scale. The study findings provide new data suggesting that, with the exception of secondary traumatic stress, the personal well-being of nurses does not differ across geographical settings. Similarly, with the exception of the subscale of 'nursing foundations for quality care' there was no difference in perceptions of the professional practice environment. As secondary traumatic stress is associated with burnout, this finding needs to be investigated further. © 2015 National Rural

The Wernicke-Korsakoff syndrome: a reappraisal in Queensland with special reference to prevention.

Science.gov (United States)

Price, J; Kerr, R; Hicks, M; Nixon, P F

The Wernicke-Korsakoff syndrome occurs most frequently in alcoholic patients when they become thiamin deficient. First admissions to psychiatric units with the chronic component of this syndrome, Korsakoff's psychosis, peaked in Queensland in 1975-1976. The fall in hospital admission rates since this time could relate to a decline in per-capita alcohol consumption in Australia, or to more awareness of the thiamin needs of drinkers. Alternatively, the improvement may be illusory: although many cases of Wernicke's encephalopathy are being diagnosed, many of these patients are not receiving psychiatric assessment and treatment, perhaps because admission to psychiatric hospital beds is more difficult than it was formerly. Patients who are diagnosed as having Korsakoff's psychosis fare badly in the community, and have a greatly increased mortality rate than do such patients in hospital. Optimal care for such patients is necessarily costly of medical resources. Of available preventive measures, evidence is presented to support the fortification of beer with thiamin and the provision of community educational programmes. The fortification of flour with thiamin may have little impact on the thiamin-deficiency syndromes that arise in problem drinkers in Queensland.

Pequi fruit (Caryocar brasiliense Camb.) pulp oil reduces exercise-induced inflammatory markers and blood pressure of male and female runners.

Science.gov (United States)

Miranda-Vilela, Ana L; Pereira, Luiz C S; Gonçalves, Carlos A; Grisolia, Cesar K

2009-12-01

The objective of this study was to investigate the anti-inflammatory properties of pequi (Caryocar brasiliense) fruit oil and its effects on the postprandial lipidemia and arterial blood pressure of male and female athletes. These athletes were evaluated after races in the same environment and under the same type, intensity, and length of weekly training conditions, both before and after ingestion of 400 mg pequi oil capsules for 14 days. Pequi fruit contains several antioxidants, and its oil has been associated with anti-inflammatory properties in other pequi species. Because the oil of pequi is mostly composed of oleic and palmitic fatty acids, the oil may alter the ratio of triglyceride to cholesterol in postprandial lipidemia. Epidemiologic studies suggest that an increased intake of monounsaturated fatty acids (such as oleic acid) is inversely related to blood pressure. Thus, we hypothesize that pequi oil could reduce exercise-induced inflammation and blood pressure, and modulate postprandial lipidemia in runners. To test this hypothesis, arterial blood pressures were checked before races; blood samples were taken after the races and submitted for analysis of leukocytes and platelets analysis, high-sensitivity C-reactive protein values, and postprandial lipids. Pequi oil resulted in anti-inflammatory effects and reduced the total cholesterol and low-density lipoprotein in the age group older than 45 years, mainly for men. The results showed a general trend for reduced arterial pressure, suggesting that pequi oil may have a hypotensive effect. However, this finding needs additional investigation. Thus, pequi oil, besides possessing many nutritional properties, may be a good candidate supplement for athletes.

Using Microsimulation to Estimate the Future Health and Economic Costs of Salmonellosis under Climate Change in Central Queensland, Australia.

Science.gov (United States)

Stephen, Dimity Maree; Barnett, Adrian Gerard

2017-12-11

The incidence of salmonellosis, a costly foodborne disease, is rising in Australia. Salmonellosis increases during high temperatures and rainfall, and future incidence is likely to rise under climate change. Allocating funding to preventative strategies would be best informed by accurate estimates of salmonellosis costs under climate change and by knowing which population subgroups will be most affected. We used microsimulation models to estimate the health and economic costs of salmonellosis in Central Queensland under climate change between 2016 and 2036 to inform preventative strategies. We projected the entire population of Central Queensland to 2036 by simulating births, deaths, and migration, and salmonellosis and two resultant conditions, reactive arthritis and postinfectious irritable bowel syndrome. We estimated salmonellosis risks and costs under baseline conditions and under projected climate conditions for Queensland under the A1FI emissions scenario using composite projections from 6 global climate models (warm with reduced rainfall). We estimated the resulting costs based on direct medical expenditures combined with the value of lost quality-adjusted life years (QALYs) based on willingness-to-pay. Estimated costs of salmonellosis between 2016 and 2036 increased from 456.0 QALYs (95% CI: 440.3, 473.1) and AUD29,900,000 million (95% CI: AUD28,900,000, AUD31,600,000), assuming no climate change, to 485.9 QALYs (95% CI: 469.6, 503.5) and AUD31,900,000 (95% CI: AUD30,800,000, AUD33,000,000) under the climate change scenario. We applied a microsimulation approach to estimate the costs of salmonellosis and its sequelae in Queensland during 2016-2036 under baseline conditions and according to climate change projections. This novel application of microsimulation models demonstrates the models' potential utility to researchers for examining complex interactions between weather and disease to estimate future costs. https://doi.org/10.1289/EHP1370.

Queensland Energy Advisory Council (QEAC) role covers all forms of energy including renewable, non-renewable, commercialised and non-commercialised energy forms or proposals. While coal developments and electricity matters are discussed and monitored at meetings, the Mines Department and the State Electricity Commission, respectively, retain responsibility for most aspects in these energy sectors. In such cases QEAC's expertise and role is limited and is advisory. In other areas such as energy conservation, management of liquid fuel emergencies, natural gas supply and demand, solar energy, coal conversion, and ethanol production, QEAC made a significant contribution to policy development in 1981/82.

2006-12-01

The aim of the study was to identify the factors having an impact upon nursing work and to use the results to inform strategic planning of the Queensland Nurses Union. In 2001 and 2004, a study was undertaken to gather data on the level of satisfaction of nurses with their working life. This paper reports the 2004 results on workload, skill mix, remuneration and morale. Where applicable, the results are compared with 2001 data. A questionnaire was mailed to 3000 Assistants-in-Nursing, Enrolled and Registered Nurses in October 2004. All participants were members of the Queensland Nurses Union. The results are reported in three sectors - public, private and aged care. A total of 1349 nurses responded to the survey, a response rate of 45%. Nurses in the 2004 study believed: their workload was heavy; their skills and experience poorly rewarded; work stress was high; morale was perceived to be poor and, similar to 2001, deteriorating; the skill mix was often inadequate; and the majority of nurses were unable to complete their work in the time available. Nursing morale was found to be associated with autonomy, workplace equipment, workplace safety, teamwork, work stress, the physical demand of nursing work, workload, rewards for skills and experience, career prospects, status of nursing and remuneration. Overall the findings of the study are consistent with those determined by the 2001 survey. The findings of this study indicate the importance of factors such as workplace autonomy, teamwork, the levels of workplace stress, workload and remuneration on nursing morale. The data also indicate that workplace safety and workplace morale are linked. These findings provide information for policy makers and nurse managers on areas that need to be addressed to retain nurses within aged care, acute hospital and community nursing.

The Distribution and Density of Water Mice (Xeromys myoides in the Maroochy River of Southeast Queensland, Australia.

Directory of Open Access Journals (Sweden)

Janina Kaluza

Full Text Available The water mouse is a small and vulnerable rodent present in coastal areas of south-west Papua New Guinea, and eastern Queensland and the Northern Territory of Australia. Current knowledge regarding the distribution of the water mouse is incomplete and the loss of one local population has been documented in southeast Queensland, a region where pressures from urban and industrial development are increasing. Water mouse populations have not been studied intensively enough to enable the primary factors responsible for the local decline to be identified. We surveyed the distribution and density of the water mouse along the Maroochy River of southeast Queensland, near the southern extent of the species' range, to gather baseline data that may prove valuable for detecting any future decline in this population's size or health. All areas of suitable habitat were surveyed on foot or by kayak or boat over a three-year period. We found 180 water mouse nests, of which ~94% were active. Permanent camera monitoring of one nest and limited supplementary live trapping suggested that up to three individual mice occupied active nests. Water mouse density was estimated to be 0.44 per hectare of suitable habitat along the Maroochy River. Should future monitoring reveal an adverse change in the water mouse population on the Maroochy River, a concerted effort should be made to identify contributing factors and address proximate reasons for the decline.

Random breath testing in Queensland and Western Australia: examination of how the random breath testing rate influences alcohol related traffic crash rates.

Ferris, Jason; Mazerolle, Lorraine; King, Mark; Bates, Lyndel; Bennett, Sarah; Devaney, Madonna

2013-11-01

In this paper we explore the relationship between monthly random breath testing (RBT) rates (per 1000 licensed drivers) and alcohol-related traffic crash (ARTC) rates over time, across two Australian states: Queensland and Western Australia. We analyse the RBT, ARTC and licensed driver rates across 12 years; however, due to administrative restrictions, we model ARTC rates against RBT rates for the period July 2004 to June 2009. The Queensland data reveals that the monthly ARTC rate is almost flat over the five year period. Based on the results of the analysis, an average of 5.5 ARTCs per 100,000 licensed drivers are observed across the study period. For the same period, the monthly rate of RBTs per 1000 licensed drivers is observed to be decreasing across the study with the results of the analysis revealing no significant variations in the data. The comparison between Western Australia and Queensland shows that Queensland's ARTC monthly percent change (MPC) is 0.014 compared to the MPC of 0.47 for Western Australia. While Queensland maintains a relatively flat ARTC rate, the ARTC rate in Western Australia is increasing. Our analysis reveals an inverse relationship between ARTC RBT rates, that for every 10% increase in the percentage of RBTs to licensed driver there is a 0.15 decrease in the rate of ARTCs per 100,000 licenced drivers. Moreover, in Western Australia, if the 2011 ratio of 1:2 (RBTs to annual number of licensed drivers) were to double to a ratio of 1:1, we estimate the number of monthly ARTCs would reduce by approximately 15. Based on these findings we believe that as the number of RBTs conducted increases the number of drivers willing to risk being detected for drinking driving decreases, because the perceived risk of being detected is considered greater. This is turn results in the number of ARTCs diminishing. The results of this study provide an important evidence base for policy decisions for RBT operations. Copyright © 2013 Elsevier Ltd. All

Gender inequality in predispersal seed predation contributes to female seed set advantage in a gynodioecious species.

Science.gov (United States)

Clarke, Gretel L; Brody, Alison K

2015-05-01

Most flowering plants are hermaphrodites. However, in gynodioecious species, some members of the population are male-sterile and reproduce only by setting seed, while others gain fitness through both male and female function. How females compensate for the loss of male function remains unresolved for most gynodioecious species. Here, as with many plants, fitness differences may be influenced by interactions with multiple species. However, whether multiple species interactions result in gender-specific fitness differences remains unknown. Using observational data from 2009-2010, we quantified seed set of the two sex morphs of Polemonium foliosissimu and asked how it is affected by pollination, and seed predation from a dipteran predispersal seed predator (Anthomyiidae: Hylemya sp.). We assessed seed production and losses to predation in 27 populations for one year and in six populations for a second year. Females set significantly more seed than did hermaphrodites in both years. Of the fitness components we assessed, including the number of flowers per plant, fruit set, seeds/fruit, and proportion of fruits destroyed by Hylemya, only fruit destruction differed significantly between the sexes. In one year, seeds/fruit and predation had a stronger effect on seed set for hermaphrodites than for females. Because predispersal seed predators do not pollinate flowers, their effects may depend on successful pollination of flowers on which they oviposit. To examine if genders differed in pollen limitation and seed predation and/or their interactive effects, in 2011 we hand-pollinated flowers and removed seed predator eggs in a fully factorial design. Both sexes were pollen limited, but their degree of pollen limitation did not differ. However, predation reduced.seed set more for hermaphrodites than for females. We found no significant interaction between hand pollen and seed predation, and no interaction between hand pollination and gender. Our results suggest that while

The purpose of this study was to understand the methods of current delivery of health care services to cerebral palsy (CP) patients in Queensland, Australia. The study also examines the current use of telehealth by clinicians and their perceptions about telehealth use. Patient records during July 2013-July 2014 were accessed from the Queensland Paediatric Rehabilitation Service (QPRS) to collect information relating to the service delivery for CP patients. Analysis was carried out to examine the patient locations and travel distances using ArcMap geoprocessing software. In addition, 13 face-to-face semi structured interviews were conducted with clinicians from the QPRS and the Cerebral Palsy Health Service (CPHS) to understand the perceptions of clinicians relating to the current level of health care delivery. We also examined the clinicians' current use of telehealth and their opinions about this method. Records of 329 paediatric CP patients were accessed and reviewed. The majority of patients (96%, n = 307) who attended the clinics at the Royal Children's Hospital (RCH), Brisbane, were from remote, rural or regional areas of Queensland. Only 4% of patients (n = 13) were from major cities. During 12 months, patients had attended nine outreach programmes that were conducted by the QPRS and CPHS. The study found that non-local patients were required to travel an average distance of 836 km to access QPRS and CPHS services in Brisbane. The average distance for receiving a consultation at an outreach clinic was 173 km. Clinicians perceived that access to health care services to CP patients in Queensland is inadequate. Nearly all clinicians interviewed had some experience in using telehealth. They had high satisfaction levels with the method. Traditional methods of delivering services to CP patients do not meet their needs. Clinicians have found telehealth is a feasible and satisfactory delivery method. However, the use of telehealth is still limited. © The

The main objective of this study is to describe incidence rates of low-speed vehicle run-over (LSVRO) events among children aged 0-14 years residing in Queensland from 1999 to 2009. A second objective was to describe the associated patterns of injury, with respect to gender, age group, severity, characteristics (host, vehicle and environment), and trends over time in relation to geographical remoteness. Final results are hoped to inform prevention policies. In this statewide, retrospective, population-based study, data were collected on LSVRO events that occurred among children aged 0-14 years in Queensland from 1999 to 2009 from all relevant data sources across the continuum of care, and manually linked to obtain the most comprehensive estimate possible of the magnitude and nature of LSVRO events to date. Crude incidence rates were calculated separately for males and females, for fatal events, non-fatal events (hospital admissions and non-admissions, respectively), and for all LSVRO events, for each area of geographical remoteness (major cities, inner regional, outer regional, remote/very remote). Relative risks and 95% confidence interval were calculated, and trends over time were examined. Data on host, injury and event characteristics were also obtained to investigate whether these characteristics varied between areas of remoteness. Incidence rates were lowest among children (0-14 years) living in major cities (13.8/100 000/annum, with the highest recorded incidence in outer regional areas (incidence rate =42.5/100 000/annum). Incidence rates were higher for children residing outside major cities for both males and females, for every age group, for each of the 11 years of the study, and consequences of LSVRO events were worse. Young children aged 0-4 years were identified as those most at risk for these events, regardless of geographical location. Differences were observed as a function of remoteness category in relation to injury characteristics (eg injury

Mediterranean fruit fly female attractant studies in support of the sterile insect technique: trapping experiments conducted on the island of Chios, Greece

1999-01-01

This paper contains information on a four-year research programme co-ordinated by the International Atomic Energy Agency. The main objective of the programme was to develop a trapping system for females of the Mediterranean fruit fly (medfly), Ceratitis capitata (Diptera: Tephritidae), for practical use in Sterile Insect Technique (SIT) programs and to design and evaluate a trap to obtain eggs from wild female medflies in order to estimate sterility induction in the field population. The experiments were conducted from July to September 1994-1997 on the island of Chios, Greece, in citrus orchards with low to medium medfly populations. Different trap types and several trap treatments consisting of sex and food based attractants were tested, following a standard coordinated experimental protocol. The most extensively tested were three food based 'female' attractants (FA-3), namely ammonium acetate (AA), 1,4 diaminobutane (putrescine) and trimethylamine, all formulated in dispensers lasting one month. These attractants were evaluated in combinations of two (AA + putrescine, termed FA-2) or three (FA-3) dispensers in various traps, including dry (provided with DDVP) or wet (provided with water and 0.01% surfactant) plastic International Pheromone's McPhail traps (IPMT). Among the various traps and treatments tested, the most effective for medfly capture was the wet IPMT, baited with FA-3 attractants. This treatment captured predominantly females and was relatively selective for medflies. In dry IPMT traps, the FA-3 were as effective as the standard 300 ml aqueous solution of 9% of the protein NuLure and 3% borax, but much more medfly selective. Dry IPMT traps were also more selective than wet ones. FA-3 baited wet Tephri traps (a Spanish modification of the McPhail trap), performed somewhat poorer than IPMT traps. Other dry trap types tested were not effective. Additional experiments showed that certain insecticide formulations used in dry traps may have a repellent

On interception modelling of a lowland coastal rainforest in northern Queensland, Australia

Science.gov (United States)

Wallace, Jim; McJannet, Dave

2006-10-01

SummaryRecent studies of the water balance of tropical rainforests in northern Queensland have revealed that large fractions of rainfall, up to 30%, are intercepted by the canopy and lost as evaporation. These loss rates are much higher than those reported for continental rainforests, for example, in the Amazon basin, where interception is around 9% of rainfall. Higher interception losses have been found in coastal and mountain rainforests and substantial advection of energy during rainfall is proposed to account for these results. This paper uses a process based model of interception to analyse the interception losses at Oliver Creek, a lowland coastal rainforest site in northern Queensland with a mean annual rainfall of 3952 mm. The observed interception loss of 25% of rainfall for the period August 2001 to January 2004 can be reproduced by the model with a suitable choice of the three key controlling variables, the canopy storage capacity, mean rainfall rate and mean wet canopy evaporation rate. Our analyses suggest that the canopy storage capacity of the Oliver Creek rainforest is between 3.0 and 3.5 mm, higher than reported for most other rainforests. Despite the high canopy capacity at our site, the interception losses can only be accounted for with energy advection during rainfall in the range 40-70% of the incident energy.

Contemporary health-promotion programs in settings such as schools, workplaces and hospitals use organisational development theory to address the health issues of the setting, including the physical environment, the organisational environment, and the specific health needs of the employees and consumers of the service. Program principles include management of each project by the participant organisation or site (for example, a school or workplace), using resources available within the organisation and the local community, voluntary participation, social justice and participant-based priority setting, and evaluation and monitoring. Adoption of these principles implies a shift in the role of the health worker from implementer to facilitator. Based on the experience of Queensland Health, it is proposed that the essential building blocks of the health-promoting-environments program are an intersectoral policy base, a model for action, training and resources, local facilitators, support from local organisations, a supportive network of sites, marketing of the program, and a state-based evaluation and monitoring system. The program in Queensland was able to develop a significant number of these components over the 1990-1996 period. In regard to evaluation, process measures can be built around the program components; however, further research is required for development of impact indicators and benchmarks on quality.

Objective The aim of the present study was to examine care pathways and characteristics of mental health consumers participating in both hospital- and community-based residential rehabilitation programs. Methods An audit of consumers (n=240) in all publicly funded residential rehabilitation units in Queensland was performed on the same day in 2013. Data collection focused on demographic characteristics, clinical information and measures of consumer functioning. Results Significant differences emerged for consumers in community- and hospital-based services with regard to age, length of stay, functioning, Mental Health Act status, guardianship status, family contact and risk of violence. Consumers in hospital-based programs have more severe and complex problems. Conclusions Consumers in residential rehabilitation units have high levels of disability, poor physical health and high levels of vulnerability. Nonetheless, it is likely that a sizeable proportion of consumers occupying rehabilitation beds in Queensland could be discharged if more 'step-down' options to move patients on were available. What is known about the topic? A small subgroup of people with severe and complex mental health problems is likely to require time in a residential rehabilitation program. This group is characterised by failure to respond to treatment, severe negative symptoms and some degree of cognitive impairment. What does this paper add? Patients currently occupying residential rehabilitation beds in Queensland have high levels of disability, poor physical health and high levels of vulnerability. Patients in hospital-based programs are more severely disabled than those in community-based programs. What are the implications for practitioners? It is likely that a sizeable proportion of patients occupying rehabilitation beds in Queensland could be discharged if more 'step-down' options were available. Future planning initiatives need to focus on developing a greater array of community

Conclusions: In this endemic region of north Queensland, exposure to wildlife and seasonal rainfall may be substantial exposure factors for the development of Q fever. The region studied is a popular tourist destination. An understanding of risk factors involved can help practitioners who see residents or returned travelers from the region, with an undifferentiated fever.

Major gene mutations in fruit tree domestication

International Nuclear Information System (INIS)

Spiegel-Roy, P.

1989-01-01

Though fruit gathering from the wild began long before domestication, fruit tree domestication started only after the establishment of grain agriculture. Banana, fig, date, grape and olive were among the first fruit trees domesticated. Most fruit trees are outbreeders, highly heterozygous and vegetatively propagated. Knowledge of genetics and economic traits controlled by major genes is limited. Ease of vegetative propagation has played a prominent part in domestication; advances in propagation technology will play a role in domestication of new crops. Changes toward domestication affected by major genes include self-fertility in peach, apricot and sour cherry, while the emergence of self-fertile almond populations is more recent and due probably to introgression from Amygdalus webbii. Self-compatibility in the sweet cherry has been attained only by pollen irradiation. A single gene controls sex in Vitis. Wild grapes are dioecious, with most domesticated cultivars hermaphrodite, and only a few females. In the papaya changes from dioecism to hermaphroditism have also occurred. Self-compatible systems have also been selected during domestication in Rubus. Changes towards parthenocarpy and seedlessness during domestication occurred in the banana, citrus, grape, fig and pineapple. In the banana, parthenocarpy is due to three complementary dominant genes; stenospermocarpy in the grape depends on two complementary recessive genes; parthenocarpy and sterility in citrus seems more complicated; however, it can be induced in genetic material of suitable background with ease by irradiation. Presence of persistent syconia in the fig is controlled by a mutant allele P dominant to wild +. Thornlessness in blackberry is recessive, while in the pineapple spineless forms are dominant. Changes affecting fruit composition owing to major genes include the disappearance of amygdalin present in bitter almonds (bitter kernel recessive to sweet), shell hardness in almond, and a recessive

Full text: In a recent review the authors, Wolfgang Baumeister and Alasdair Steven wrote, '....there is immense opportunity for Cryo-EM, especially as boosted by merging crystallographic structures of individual subunits into moderate resolution Cryo-EM density maps of whole complexes. Electron tomography has now advanced to the point where it is a realistic goal to glimpse molecular machines operating inside cells....' This statement gives testament to the advances made over the past 25 years by many labs around the world to the area of microscopy referred to as Cryo-EM and related 3-D computing technologies. Australian scientific societies have been eager followers of this progress and heard first hand of the new developments in the field at the 1984 ACEM-8 (2). Since those early days the ACEM and other Australian/NZ societies have sponsored numerous researchers and workshops in the field of Cryo-EM to their conferences, Helin Sabil, Wah Chiu, Ron Milligan, Richard Henderson and Werner Kuhlbrandt to name only a few. These visits have stimulated a desire from Australian/NZ researchers to establish collaborations and access to prominent labs in the USA and Europe, where the means and knowledge to provide Cryo EM and 3D reconstruction technology for studying macromolecular complexes is well established. However, Australia has not been backward in seeking to provide its home research community with access to a base in biological molecular microscopy and electron crystallography technology. Since the last ACEM we have seen the emergence of a number of crucial factors, which will make the establishment of a national research facility in this field an operational reality in early 2003. Well publicized is the development of Australia's newest and perhaps most unique research institute, the institute for Molecular Bioscience (IMB) to open at the University of Queensland (UQ) in 2002. The IMB will be the platform for a new research group in advanced computational 3D

A disease outbreak investigation was conducted in western Queensland to investigate a rare suspected outbreak of pyrrolizidine alkaloid (PA) toxicosis in horses. Thirty five of 132 horses depastured on five properties on the Mitchell grass plains of western Queensland died in the first six months of 2010. Clinical-pathological findings were consistent with PA toxicosis. A local variety of Crotalaria medicaginea was the only hepatotoxic plant found growing on affected properties. Pathology reports and departure and arrival dates of two brood mares provided evidence of a pre wet season exposure period. All five affected properties experienced a very dry spring and early summer preceded by a large summer wet season. The outbreak was characterised as a point epidemic with a sudden peak of deaths in March followed by mortalities steadily declining until the end of June. The estimated morbidity (serum IGG>50IU/L) rate was 76%. Average crude mortality was 27% but higher in young horses (67%) and brood mares (44%). Logistic regression analysis showed that young horses and brood mares and those grazing denuded pastures in December were most strongly associated with dying whereas those fed hay and/or grain based supplements were less likely to die. This is the first detailed study of an outbreak of PA toxicosis in central western Queensland and the first to provide evidence that environmental determinants were associated with mortality, that the critical exposure period was towards the end of the dry season, that supplementary feeding is protective and that denuded pastures and the horses physiological protein requirement are risk factors.

Acid-mine drainage (AMD) into the Dee River from the historic gold and copper mine in Mount Morgan, Queensland (Australia) has been of concern to farmers in the area since 1925. This study sought to determine the levels of AMD-related metals and sulfur in agricultural produce grown near the mine-impacted Dee River, compare these with similar produce grown in reference fields (which had no known AMD influence), and assess any potential health risk using relevant Australian or US guidelines. Analyses of lucerne (Medicago sativa; also known as alfalfa) from five Dee fields showed the following average concentrations (mg/kg dry basis): Cd < 1, Cu 11, Fe 106, Mn 52, Pb < 5, Zn 25 and S 3934; similar levels were found in lucerne hay (used as cattle feed) from two Dee fields. All lucerne and lucerne hay data were generally comparable with levels found in the lucerne reference fields, suggesting no AMD influence; the levels were within the US National Research Council (US NRC) guidelines for maximum tolerable cattle dietary intake. Pasture grass (also cattle feed) from two fields in the Dee River floodplains gave mean concentrations (mg/kg dry) of Cd 0.14, Cu 12, Fe 313, Mn 111, Pb 1.4, Zn 86 and S 2450. All metal levels from the Dee and from reference sites were below the US NRC guidelines for maximum tolerable cattle dietary intake; however, the average Cd, Cu and Fe levels in Dee samples were significantly greater than the corresponding levels in the pasture grass reference sites, suggesting AMD influence in the Dee samples. The average levels in the edible portions of mandarin oranges (Citrus reticulata) from Dee sites (mg/kg wet weight) were Cd 0.011, Cu 0.59, Fe 2.2, Mn 0.56, Pb 0.18, S 91 and Zn 0.96. Cd and Zn were less than or close to, average Fe and Mn levels were at most twice, Cd 1.8 or 6.5 times, and Pb 8.5 or 72 times the maximum levels in raw oranges reported in the US total diet study (TDS) or the Australian TDS, respectively. Average Cd, Fe, Mn, Pb and

Full Text Available Our goal was to identify the bacteria inhabiting the reproductive system of the female oriental fruit fly, Bactrocera dorsalis (Hendel, and evaluate the chemotaxis of B. dorsalis to the metabolites produced by the bacteria. Based on 16S rRNA-based polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE, 18 operational taxonomic units (OTUs were assigned to the five bacterial classes Betaproteobacteria, Alphaproteobacteria, Gammaproteobacteria, Bacilli and Actinobacteria. Nine OTUs were assigned to Gammaproteobacteria, which was the most highly represented class. Enterobacteriaceae constituted the dominant family, and within this family, three genera and five species were identified, including Enterobacter sakazakii, Klebsiella oxytoca, Klebsiella pneumoniae, Raoultella terrigena and Enterobacter amnigenus. In this set, the first two species were the dominant components, and the latter three species were the minor ones. Finally, we found that the metabolites produced by R. terrigena, K. oxytoca and K. pneumoniae were attractive to the B. dorsalis adults, and in field studies, B. dorsalis adults were most attracted to K. oxytoca. Collectively, our results suggest that the female reproductive system plays an important role in the transfer of enterobacteria from the gut to fruit. Our data may prompt the development of a female-targeted population control strategy for this fly.

We investigate whether these geographical patterns have changed over time using population-based data linkage between cancer registry records and hospital inpatient episodes. The study cohort consisted of 11,631 women aged 20 years and over diagnosed with a single primary invasive localised breast cancer between 1997 and 2011 in Queensland, Australia who underwent either BCS (n = 9223, 79% or mastectomy (n = 2408, 21%.

The association between accessibility and the type of surgery reduced over time (interaction p = 0.028 but not for area disadvantage (interaction p = 0.209. In making informed decisions about surgical treatment, it is crucial that any geographical-related barriers to implementing their preferred treatment are minimised.

To analyze breakfast consumption, regularity of meals, fruit and vegetable consumption in the Italian university student population on a national level. Descriptive analysis evaluating data taken from the Sportello Salute Giovani (SSG) questionnaire. 12 000 university students who self-administered a confidential survey. 8292 questionnaires were analyzed. Age; sex; self-reported economic status; BMI; number of breakfast and portions of vegetables and portions of fruit usually consumed per week; number of eating episodes per day; intended weight loss. Descriptive and logistic regression analyses were conducted. Gender and age differences were tested by c2 and Mann-Whitney tests. 15.8% of males and 26.3% of females declared to consume at least one portion of fruit every day. Similar results were found for vegetable consumption. Age does not influence fruit or vegetables consumption, frequency of eating episodes or breakfast habit. Both a regular breakfast and a higher number of eating episodes are significantly associated both with a higher frequency of fruit and vegetables intake. This study underlines the need to promote nutritional education campaigns to increase adherence to nutritional guidelines.

The sterile insect technique for the Oriental fruit fly was pilot tested in Naoway, a 12-ha islet about 1.5 km. southeast of Guimaras island. The Oriental fruit fly population (male) in the islet was first estimated at 3,432 using the mark-release-recapture experiments. From August to October 1995, six releases of sterile fruit flies (male and female) at biweekly intervals were conducted in the islet. Except for the 7 wild fruit flies collected by a trap 10 days after the first release, not a single fly was collected from the pilot site thereafter. Furthermore, field collections of infested fruits yield only 6 pupae on the first and zero on the subsequent collections. The results suggested that SIT proved successful in Naoway islet. For Guimaras, an island-wide implementation of SIT could be undertaken after reducing the wild male fruit fly population by field sanitation and the male annihilation method in order to overflood the wild population with sterile fruit flies.

Airborne radiometric surveys measure the potassium, thorium and uranium concentrations in the topmost 20-30cm of the earth. These datasets are now routinely used for geological interpretations and for defining exploration targets. The survey results are commonly presented as colour composite images of potassium-thorium-uranium distribution, and large copies of these colourful posters are commonplace on the walls of geological offices. However, in many cases, the data are not interpreted to their full potential. Further options exist for their evaluation. including determining potassium-thorium trends and the distribution of residuals across a prospective geological unit. This study of radiometric data over the Rookwood Volcanics near Gogango in central Queensland has detected areas of radio-element concentration and depletion. Comparison with known mineral occurrences suggests that some of these areas may be associated with copper mineralisation

Full Text Available The study presented in this paper makes a constituent part of another study dedicated to the development of food consumer science in the Western Balkans. The paper presents a part of the most relevant findings that the authors have obtained and analyzed from thirty in-depth interviews conducted with fruit consumers in Serbia. Main motives and barriers for consumption of fruit among urban and rural as well as male and female respondents are explored and elaborated. Additionally, existence of particular stereotypes of fruit consumers and non-consumers revealed through implemented projective technique is also discussed in this paper. The findings presented support general theoretical knowledge obtained from various food consumer studies previously conducted in more developed economies.

Fellatio by fruit bats prolongs copulation time.

Directory of Open Access Journals (Sweden)

Min Tan

Full Text Available Oral sex is widely used in human foreplay, but rarely documented in other animals. Fellatio has been recorded in bonobos Pan paniscus, but even then functions largely as play behaviour among juvenile males. The short-nosed fruit bat Cynopterus sphinx exhibits resource defence polygyny and one sexually active male often roosts with groups of females in tents made from leaves. Female bats often lick their mate's penis during dorsoventral copulation. The female lowers her head to lick the shaft or the base of the male's penis but does not lick the glans penis which has already penetrated the vagina. Males never withdrew their penis when it was licked by the mating partner. A positive relationship exists between the length of time that the female licked the male's penis during copulation and the duration of copulation. Furthermore, mating pairs spent significantly more time in copulation if the female licked her mate's penis than if fellatio was absent. Males also show postcopulatory genital grooming after intromission. At present, we do not know why genital licking occurs, and we present four non-mutually exclusive hypotheses that may explain the function of fellatio in C. sphinx.

There are very few studies on the frequency of breakfast and snack consumption and its relation to fruit and vegetable intake. This study aims to fill that gap by exploring the relation between irregular breakfast habits and snack consumption and fruit and vegetable intake in Tuscan adolescents. Separate analyses were conducted with an emphasis on the potentially modifying factors of sex and age. Data was obtained from the 2010 Tuscan sample of the Health Behaviour in School-aged Children (HBSC) study. The HBSC study is a cross-sectional survey of 11-, 13- and 15-year-old students (n = 3291), selected from a random sample of schools. Multivariate logistic regression was used for analyzing the food-frequency questionnaire. A significant relation was found between low fruit and vegetable intake and irregular breakfast habits. Similarly, low fruit intake was associated with irregular snack consumption, whereas vegetable intake did not prove to be directly related to irregular snack consumption. Different patterns emerged when gender and age were considered as modifying factors in the analyses. A statistically significant relation emerged only among female students for irregular breakfast habits and fruit and vegetable intake. Generally, older female participants with irregular breakfast habits demonstrated a higher risk of low fruit and vegetable intake. Age pattern varied between genders, and between fruit and vegetable consumption. Results suggest that for those adolescents who have an irregular consumption of breakfast and snacks, fruit intake occurs with a lower frequency. Lower vegetable consumption was associated with irregular breakfast consumption. Gender and age were shown to be moderators and this indicated the importance of analyzing fruit and vegetable intake and meal types separately. This study also confirmed that health-promotion campaigns that aim to promote regular meal consumption and consumption of fruits and vegetables need to take into account

The aim of the present study was to evaluate the effect of a hydro-alcoholic extract of Vitex agnus-castus (VAC) fruit on blood urea nitrogen (BUN), creatinine (Cr) and, kidney histology of a female mouse model of D-galactose induced aging. In this experimental study, 72 NMRI mice were divided into 6 groups: control, VAC, D-galactose, D-galactose+VAC, aging, and aging+VAC. D-galactose was injected for 45 days and, VAC extract administered in the last 7 days, twice a day. Serum BUN and Cr levels were not significantly changed in the D-galactose and natural aged animals in comparison to control group. Histological changes such as nuclear pyknosis, proximal cell swelling, infiltration of inflammatory cells, tubular dilatation and, vasodilatation were observed in both D-galactose and natural aged mice. Further, glomerules diameter was decreased in them. Administration of VAC could attenuate the histological alterations. These results indicate that VAC may have beneficial effects on aging and aging related kidney disease.

Copulation and sperm transfer were observed between wild flies and sterile flies of Bactrocera dorsalis (Hendel) and Bactrocera correcta (Bezzi) in cages. 8-day old pupae of B. dorsalis and B. correcta were irradiated with gamma rays at 90 and 80 gray respectively. Wild flies from infested fruits and sterile flies from artificial diet in the labolatory were used for testing. The experiments were conducted 3 treatments and 3 replications. The ratio of sterile male : wild male: wild female were 3:1:1 by using sterile male of B. dorsalis: wild male of B. correcta : wild female of B. correcta and sterile male of B. correcta: wild male of B. dorsalis: wild female of B. dorsalis as 60:20:20 flies respectively. The experiment found 69 pairs of copulation consisting of 3 mating pairs(4.3%) of wild male with wild female of B. dorsalis, 22 mating pairs (31.9%) of wild male with wild female of B. correcta, 2 mating pairs(2.9%) of sterile male of B dorsalis with wild female of B. correcta, 42 mating pairs(60.9%) of sterile male of B. correcta with wild female of B. dorsalis. The cages which ratio 1:1 consisted of wild B. dorsalis and wild B. correcta (male and female = 50:50 flies) were observed and found that 43 pairs of copulation such as 2 mating pairs (4.6%) of wild male with wild female of B. dorsalis, 26 mating pairs (60.5%) of wild male with wild female of B. correcta, 2 mating pairs(2.9%) of sterile male of B. dorsalis with wild female of B. correcta and 15 mating pairs(34.9%) of wild male of B. correcta with wild female of B. dorsalis. Mated female flies were separated from male flies. Egg hatch and sperm were checked. The hatchability of normal copulation of B. dorsalis and B. correcta were 81 and 90%. The average sperm level in spermathecae of normal copulation of B. dorsalis and B. correcta were 2.2 and 2.3 respectively but had no sperm in their spemathecae of females of interspecific copulations Mating behavior of both species began in the evening before sunset at

To evaluate the feasibility and reliability of record linkage of existing population-based data sets to determine Indigenous status among women receiving Pap smears. This method may allow for the first ever population measure of Australian Indigenous women's cervical screening participation rates. A linked data set of women aged 20-69 in the Queensland Pap Smear Register (PSR; 1999-2011) and Queensland Cancer Registry (QCR; 1997-2010) formed the Initial Study Cohort. Two extracts (1995-2011) were taken from Queensland public hospitals data (Queensland Hospital Admitted Patient Data Collection, QHAPDC) for women, aged 20-69, who had ever been identified as Indigenous (extract 1) and had a diagnosis or procedure code relating to cervical cancer (extract 2). The Initial Study Cohort was linked to extract 1, and women with cervical cancer in the initial cohort were linked to extract 2. The proportion of women in the Initial Cohort who linked with the extracts (true -pairs) is reported, as well as the proportion of potential pairs that required clerical review. After assigning Indigenous status from QHAPDC to the PSR, the proportion of women identified as Indigenous was calculated using 4 algorithms, and compared. There were 28,872 women (2.1%) from the Initial Study Cohort who matched to an ever Indigenous record in extract 1 (n=76,831). Women with cervical cancer in the Initial Study Cohort linked to 1385 (71%) records in extract 2. The proportion of Indigenous women ranged from 2.00% to 2.08% when using different algorithms to define Indigenous status. The Final Study Cohort included 1,372,823 women (PSR n=1,374,401; QCR n=1955), and 5,062,118 records. Indigenous status in Queensland cervical screening data was successfully ascertained through record linkage, allowing for the crucial assessment of the current cervical screening programme for Indigenous women. Our study highlights the need to include Indigenous status on Pap smear request and report forms in any

Full Text Available In the western and central parts of Iran, there are more than eight million female trees of Pistacia atlantica Desf. with approximately 20,000 tons of fruit oil production ability. In order to evaluate the influence of select ecological characteristics, fruit samples of seven P. atlantica habitats in Kurdistan (Iran were collected in late October over two years (2013-14. Fruit oil was extracted using soxhlet extraction. The results showed a relatively small variation in oil content in fruit across plants of P. atlantica. The fruit oil content ranged from 25.4% to 28.4%, with a mean of 27.3%. Most habitats belonged to temperate and semi-arid regions, with higher longitude and altitude but less latitude and slope, higher soil electrical conductivity, total neutralizing value, organic carbon and clay, medium yearly rainfall, evaporation and sunny hours and also trees with medium ages such as Borban and Kashtar producing higher fruit oil yield than those that belonged to cool and semi-humid regions. Cluster analysis classified habitats into four distinct groups at 50% similarity; four habitats belonging to forest areas were located in the first, Borban and Kashtar in the second and third and Abdolmomen, with the coldest climate and the oldest trees, was in the fourth group. The results of principal component analysis (PCA revealed that habitats with low fruit oil showed extreme values of PC1 and PC2 but ones with high fruit oil were located mainly in the central zones of the bi plot, which suggest that habitats with medium ecological conditions produce higher fruit oil.

Novel insecticide strategies such as phototoxic dyes in adult fruit fly control and suppression programmes

The problems of public acceptance, ecological impact, and integration with pest management programmes associated with use of broad spectrum insecticides in bait sprays for fruit flies are being addressed in our laboratory by our development of more precisely targeted bait systems which use insecticides which are less toxic to non-target organisms. Historically, bait and insecticide sprays to control fruit flies have been used since the beginning of the 20th century. Initially, inorganic insecticides were recommended. After the Second World War, chlorinated hydrocarbon insecticides replaced inorganic ones only to be replaced by the organic ones that are used at present. Back and Pemberton (1918) stated that baits used for fruit fly control were first recommended by Mally in South Africa for the control of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), in 1908-1909 and by Berlese in Italy for the control of the olive fruit fly, Bactrocera oleae (Gmelin). The methods were improved by Lounsboury in South Africa in 1912 for the control of C. capitata and by Newman during 1913-1914 in Australia for the control of the Queensland fruit fly, Bactrocera tryoni (Froggatt). In 1910, Marsh used low-volume insecticide applications against the melon fly, Bactrocera cucurbitae (Coquillett), in Hawaii. Thereafter, other investigators adopted the low-volume approach to kill fruit flies. Whenever baits were used, they added carbohydrates and fermenting substances such as sugars, molasses, syrups, or fruit juices. In the 1930s, McPhail (1937), while working with attractants, found that sugar-yeast solutions attracted flies, and, in 1939 found that protein lures were attractive to Anastrepha species, especially to the guava fruit fly, A. striata Schiner (Baker et al. 1944). It was not until 1952, however, when Steiner demonstrated the use of hydrolysed proteins and partially hydrolysed yeast in combination with organophosphate insecticides to control fruit flies, that

The use of spatio-temporal memory has been argued to increase food-finding efficiency in rainforest primates. However, the exact content of this memory is poorly known to date. This study investigated what specific information from previous feeding visits chimpanzees (Pan troglodytes verus), in Taï National Park, Côte d'Ivoire, take into account when they revisit the same feeding trees. By following five adult females for many consecutive days, we tested from what distance the females directed their travels towards previously visited feeding trees and how previous feeding experiences and fruit tree properties influenced this distance. To exclude the influence of sensory cues, the females' approach distance was measured from their last significant change in travel direction until the moment they entered the tree's maximum detection field. We found that chimpanzees travelled longer distances to trees at which they had previously made food grunts and had rejected fewer fruits compared to other trees. In addition, the results suggest that the chimpanzees were able to anticipate the amount of fruit that they would find in the trees. Overall, our findings are consistent with the hypothesis that chimpanzees act upon a retrieved memory of their last feeding experiences long before they revisit feeding trees, which would indicate a daily use of long-term prospective memory. Further, the results are consistent with the possibility that positive emotional experiences help to trigger prospective memory retrieval in forest areas that are further away and have fewer cues associated with revisited feeding trees.

Several species of fruit flies cause serious losses to fleshy fruits in Mauritius. Due to fruit production being confined mainly to backyard gardens, traditional methods of control do not give satisfactory results. Full cover sprays with chemicals also pose potential environmental and health risks. Alternative control methods were developed and an area-wide control programme was conceived, using bait application to bring down fruit fly population, followed by intensive trapping of males, using pheromones, to keep the population at low levels. An effective attractant system for mass trapping of females integrated into the wide area programme would greatly enhance control. The use of synthetic food-based attractants for trapping Ceratitis capitata and other fruit fly species was investigated in two phases and compared with different trapping systems. In the Phase III experiments, a two component lure, ammonium acetate + putrescine (FA-2) and a three component lure, ammonium acetate + putrescine + trimethylamine (FA-3) were tested in different traps and compared with standard liquid protein-baited International Pheromone's McPhail Trap (IPMT). Frutect trap, Tephri-trap and Jackson trap with Trimedlure were also used. The medfly female catch with the FA-3 lure used in the Open Bottom Dry Trap outnumbered the catches in other traps. In Phase IV, the final year of the trial, the FA-3 lure was tested in wet and dry IPMT and Tephri traps. These were compared with IPMT containing NuLure + borax (NU+B) as standard and with locally developed traps. The FA-3 lure gave the highest catches of female medflies in the IPMT with water as retaining device followed by IPMT with DDVP, although catches were not significantly different from IPMT with NU+B.

Following the emergence of Hendra virus (HeV), private veterinarians have had to adopt additional infection control strategies to manage this zoonosis. Between 1994 and 2010, seven people became infected with HeV, four fatally. All infected people were at a higher risk of exposure from contact with horses as they were either veterinary personnel, assisting veterinarians, or working in the horse industry. The management of emerging zoonoses is best approached from a One Health perspective as it benefits biosecurity as well as a public health, including the health of those most at risk, in this case private veterinarians. In 2011 we conducted a cross-sectional study of private veterinarians registered in Queensland and providing veterinary services to horses. The aim of this study was to gauge if participants had adopted recommendations for improved infection control, including the use of personal protective equipment (PPE), and the development of HeV specific management strategies during the winter of 2011. A majority of participants worked in practices that had a formal HeV management plan, mostly based on the perusal of official guidelines and an HeV field kit. The use of PPE increased as the health status of an equine patient decreased, demonstrating that many participants evaluated the risk of exposure to HeV appropriately; while others remained at risk of HeV infection by not using the appropriate PPE even when attending a sick horse. This study took place after Biosecurity Queensland had sent a comprehensive package about HeV management to all private veterinarians working in Queensland. However, those who had previous HeV experience through the management of suspected cases or had attended a HeV specific professional education programme in the previous 12 months were more likely to use PPE than those who had not. This may indicate that for private veterinarians in Queensland personal experience and face-to-face professional education sessions may be more

There is a growing recognition of the need for criteria to determine when rehabilitation is successful or complete. Moreover, with the current emphasis on sustainability, criteria need to embrace a range of ecological attributes which in turn require an understanding of the ecosystems being created. This paper describes current research by the Centre for Mined Land Rehabilitation on ecosystem development at a number of operations throughout Queensland in the a bauxite, heavy mineral sands, gold and coal mining sectors. Case studies are presented which cover a number of ecological processes including nutrient cycling, vegetation succession and seedling recruitment. They are based in a range of different environments and encompass several different proposed end land uses. The paper demonstrates the utility of an hierarchical approach in assessing rehabilitation success, and that different elements within the hierarchy have differing levels of importance depending on specific minesite conditions. 22 refs., 3 figs.

The application of tracheal cuff pressure monitoring is likely to vary between institutions. The aim of this study was therefore to review current evidence concerning this intervention in the intensive care unit (ICU) and to appraise regional practice by performing a state-wide survey. Publications for review were identified through searches of PubMed, EMBASE and Cochrane (1977 to 2014). All studies in English relevant to critical care and with complete data were included. Survey questions were developed by small-group consensus. Public and private ICUs across Queensland were contacted, with responses obtained from a representative member of the medical or nursing staff. Existing literature suggests significant variability in tracheal cuff pressure monitoring in the ICU, particularly in the applied technique, frequency of assessment and optimal intra-cuff pressures. Twenty-nine respondents completed the survey, representing 80.5% (29/36) of ICUs in Queensland. Twenty-eight out of twenty-nine respondents reported routinely monitoring tracheal cuff function, primarily employing cuff pressure measurement (26/28). Target cuff pressures varied, with 3/26 respondents aiming for 10 to 20 cmH2O, 10/26 for 21 to 25 cmH2O, and 13/26 for 26 to 30 cmH2O. Fifteen out of twenty-nine reported they had no current guideline or protocol for tracheal cuff management and only 16/29 indicated there was a dedicated area in the clinical record for reporting cuff intervention. Our results indicate that many ICUs across Queensland routinely measure tracheal cuff function, with most utilising pressure monitoring devices. Consistent with existing literature, the optimum cuff pressure remains uncertain. Most, however, considered that this should be a routine part of ICU care.

To analyze the consumption of fruits and vegetables of Chinese adults. Data were collected from 2010-2012 China National Nutrition and Health Surveillance. Information on fruits and vegetables consumption was collected by using the 24 h recall method for 3 consecutive days. Using the multi-stage stratified cluster randomization sampling method. The participants selected were more than 18 years old of 150 counties from 31 provinces in China. Age and sex standardization was performed based on the China 2009 population published by National Statistics Bureau. The average consumption of vegetables or fruits after weight adjustment for complex sampling was reported to analyze the consumption of fruits and vegetables of Chinese adults (x ± Sx). The average daily consumptions of vegetables and fruits for Chinese residents were (255 ± 6) and (36 ± 3)g/d, respectively. The total consumptions of fruits and vegetables were (291 ± 7)g/d, (295 ± 8)g/d for male, (286 ± 7)g/d for female. Rates on intake of vegetables in Chinese adults during the three survey days were 99.0%-99.8%.Rates on intake of fruits of urban and rural residents were 36.9%-51.5% and 21.3%-30.3%,respectively.The proportion of people whose total amount of vegetables and fruits intake reached 400 g/d were 24%-28% and 13%-23% in urban and rural areas, respectively. In urban and rural areas, the proportion of adults whose consumption reached Chinese dietary guidelines recommended level were 22%-26% and 14%-19% in vegetables, 2%-5% and 1%-2% in fruit, respectively. The consumptions of vegetables and fruits were inadequate in Chinese adults.

Morgan, Edwina L; Sanday, Karen; Budd, Alison; Hammond, Ian G; Nicklin, James

2017-08-01

The current Australian National Cervical Screening Program (NCSP) involves biennial, cytology-based screening of women from the age of 18 years. From December, 2017 this will change to a five-yearly human papilloma virus-based screening commencing at age 25. There is some concern that the new program may delay the opportunistic detection of cervical cancers in women under 25 years. (1) To review all cases of invasive cervical cancer in Queensland women under the age of 25 over the last 28 years. (2) To determine symptoms and screening history prior to diagnosis. A retrospective cohort study was undertaken at the Queensland Centre for Gynaecological Cancer (QCGC) and the Queensland Cancer Registry (QCR) of all women aged between 13 and 25 years diagnosed with cervical cancer in Queensland between 1984 and 2012. Demographic data and symptoms prior to diagnosis were extracted from the QCGC and QCR databases. A total of 56 women aged 13-25, were diagnosed with cervical cancer and treated at the QCGC between 1984 and 2012. The commonest reason for the diagnosis of cancer was investigation of abnormal symptoms (n = 22, 39%) rather than routine Pap smear abnormalities (n = 15, 26%). Consistent with the world literature, there is a very low incidence of cervical cancer in women under 25 years of age, irrespective of the age of commencement of screening, or the screening interval. Our study lends some support to the proposed commencement age of 25 years in the new NCSP. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Five new species of small grass cicadas belonging to the genus Graminitigrina Ewart and Marques are described, together with detailed analyses of their calling songs. Four species occur in Queensland, G. aurora n. sp. from eastern central Queensland near Fairbairn Dam; G. flindensis n. sp. from central Queensland between Hughenden northwards for at least 108 km; G. einasleighi n. sp. from near The Lynd, Einasleigh River, northeastern Queensland; G. selwynensis n. sp. from the Selwyn Range, northwestern Queensland, at locations about 40 km east of Mount Isa and 25 km southwest of Cloncurry, this latter here transferred from G. bowensis Ewart and Marques; G. uluruensis n. sp. from Uluru and the Olgas in southwestern Northern Territory, extending northwards through Tennant Creek and apparently further north to near Larrimah, a linear distance of approximately 1190 km. These new species bring the known Graminitigrina species to ten, all superficially similar in colour and morphology. A key to male specimens is provided for the 10 species. Additional distribution records and additional aural song recordings are presented for G. bowensis, these requiring the transfer of populations previously identified as G. bowensis from Croydon and Georgetown, northern Gulf region, to G. karumbae Ewart and Marques. Detailed comparative analyses, including NMDS analyses, of the songs of all 10 species are provided, which show that the song parameters are appropriate to distinguish the species, although some partial overlap is noted in the waveform plots between the songs of G. uluruensis n. sp. and G. flindensis n. sp. Regional variations of song parameters are noted in the calling songs of most of the species described.

In 2002/03 the Queensland Government responded to high rates of alcohol-related harm in discrete Indigenous communities by implementing alcohol management plans (AMPs), designed to include supply and harm reduction and treatment measures. Tighter alcohol supply and carriage restrictions followed in 2008 following indications of reductions in violence and injury. Despite the plans being in place for over a decade, no comprehensive independent review has assessed to what level the designed aims were achieved and what effect the plans have had on Indigenous community residents and service providers. This study will describe the long-term impacts on important health, economic and social outcomes of Queensland's AMPs. The project has two main studies, 1) outcome evaluation using de-identified epidemiological data on injury, violence and other health and social indicators for across Queensland, including de-identified databases compiled from relevant routinely-available administrative data sets, and 2) a process evaluation to map the nature, timing and content of intervention components targeting alcohol. Process evaluation will also be used to assess the fidelity with which the designed intervention components have been implemented, their uptake and community responses to them and their perceived impacts on alcohol supply and consumption, injury, violence and community health. Interviews and focus groups with Indigenous residents and service providers will be used. The study will be conducted in all 24 of Queensland's Indigenous communities affected by alcohol management plans. This evaluation will report on the impacts of the original aims for AMPs, what impact they have had on Indigenous residents and service providers. A central outcome will be the establishment of relevant databases describing the parameters of the changes seen. This will permit comprehensive and rigorous surveillance systems to be put in place and provided to communities empowering them with the

2013-01-01

Full Text Available Population dynamics of the Mediterranean fruit fly was studied along Montenegro seacoast. Tephri traps baited with 3 component female-biased attractants were used in 11 different localities to monitor the fruit fly population in commercial citrus orchards, mixed-fruit orchards, and in backyards. From 2008–2010, the earliest captures were recorded no earlier than July. In 2011, the first adult fly was detected in mid-June. Low captures rates were recorded in July and August (below 0.5 flies per trap per day; FTD and peaked from mid-September to the end of October of each year. Our results indicate fluctuation of fly per trap per day depending on dates of inspection and locality, with significant differences in the adult population density. A maximum population was always reached in the area of Budva-Herceg Novi with an FTD of 66.5, 89.5, 71.63, and 24.64 (from 2008–2011 respectively. Fly activity lasts from mid-June/early-July to end December, with distinct seasonal variation in the population.

Piñero, Jaime C; Mau, Ronald F L; Vargas, Roger I

2009-06-01

The efficacy of GF-120 NF Naturalyte Fruit Fly Bait in combination with field sanitation was assessed as a control for female oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), in papaya (Carica papaya L.) orchards in Hawaii. Three different bait spray regimes were evaluated: every row (high use of the bait), every fifth row (moderate use), and every 10th row (low use). Orchard plots in which no bait was applied served as controls. For five of the seven biweekly periods that followed the first bait spray, trapping data revealed significantly fewer female B. dorsalis captured in plots subject to high and moderate bait use than in control plots. Differences in incidence of infestation among treatments were detected only by the third (12 wk after first spray) fruit sampling with significantly fewer infested one-fourth to one-half ripe papaya fruit in plots subject to high and moderate bait use than in control plots. Parasitism rates by Fopius arisanus (Sonan) (Hymenoptera: Braconidae) were not negatively affected by bait application. Results indicate that foliar applications of GF-120 NF Naturalyte Fruit Fly Bait either to all rows (every other tree), or to every fifth row (every tree) in combination with good sanitation can effectively reduce infestation by B. dorsalis in papaya orchards in Hawaii.

The effects of weather variability on seasonal influenza among different age groups remain unclear. The comparative study aims to explore the differences in the associations between weather variability and seasonal influenza, and growth rates of seasonal influenza epidemics among different age groups in Queensland, Australia. Three Bayesian spatiotemporal conditional autoregressive models were fitted at the postal area level to quantify the relationships between seasonal influenza and monthly minimum temperature (MIT), monthly vapor pressure, school calendar pattern, and Index of Relative Socio-Economic Advantage and Disadvantage for 3 age groups (Weather variability appears to be more influential on seasonal influenza transmission in younger (0-14) age groups. The growth rates of influenza at postal area level were relatively small for older (≥65) age groups in Queensland, Australia. © The Author 2017.

Sterilization of oriental fruit fly by gamma irradiation and its effect on competitiveness

International Nuclear Information System (INIS)

Manoto, E.C.; Bautista, R.C.

1975-01-01

The Oriental fruit fly, Dacus dorsalis Hendel, was irradiated with 5, 7, or 9 krad of Co-60 gamma rays at one or two days before adult eclosion. It was not clear whether or not male fruit flies were more competitive when irradiated at two days than at one day before adult eclosion. A dose of 5 krad was considered better than the higher doses of 7 or 9 krad because the higher the dosages increased percentage sterility of the male only slightly from 99.8% at 5 krad but considerably reduced male competitiveness from 72% at 5 krad to 52% at 9 krad for flies treated 2 days before emergence. The lowest dose of 5 krad was enough to prevent the female fruit flies from laying any egg. Irradiation at any of the dose levels did not affect the number of adults that emerged and the longevity of the fruit flies up to 38 days after adult eclosion

Background and Aims Some otherwise promising selections of Actinidia chinensis (kiwifruit) have fruit that are too small for successful commercialization. We have therefore made the first detailed study in diploid kiwifruit of the effects of chromosome doubling induced by colchicine on fruit size, shape and crop loading. Methods Flow cytometric analysis of young leaves and chromosome analysis of flower buds and root tips was used to confirm the stability of induced autotetraploids. Fruit weight, size and crop load were measured in the third year after planting in the field and for three consecutive years. DNA fingerprinting was used to confirm the origin of the material. Key Results There was a very significant increase in fruit size in induced autotetraploids of different genotypes of A. chinensis. With the commercially important diploid cultivar ‘Hort16A’, most regenerants, Type A plants, had fruit which were much the same shape as fruit of the diploid but, at the same fruit load, were much larger and heavier. Some regenerants, Type B plants, produced fruit similar to ‘fasciated’ fruit. Fruit of the autotetraploids induced from three female red-fleshed A. chinensis selections were also 50–60 % larger than fruit of their diploid progenitors. The main increase in fruit dimensions was in their diameters. These improved fruit characteristics were stable over several seasons. Conclusions Chromosome doubling has been shown to increase significantly fruit size in autotetraploid A. chinensis, highlighting the considerable potential of this technique to produce new cultivars with fruit of adequate size. Other variants with differently shaped fruit were also produced but the genetic basis of this variation remains to be elucidated. Autoploids of other Actinidia species with commercial potential may also show improved fruit characteristics, opening up many new possibilities for commercial development. PMID:21980192

Full Text Available Fiber and fiber-rich foods have been inversely associated with cardiovascular disease (CVD, but the evidence is scarce in young and Mediterranean cohorts. We used Cox regression models to assess the association between quintiles of total fiber and fiber from different sources, and the risk of CVD adjusted for the principal confounding factors in a Mediterranean cohort of young adults, the SUN (Seguimiento Universidad de Navarra, Follow-up cohort. After a median follow-up of 10.3 years, we observed 112 cases of CVD among 17,007 participants (61% female, mean age 38 years. We observed an inverse association between fiber intake and CVD events (p for trend = 0.024 and also between the highest quintile of fruit consumption (hazard ratio (HR 0.51, 95% confidence interval (CI 0.27–0.95 or whole grains consumption (HR 0.43 95% CI 0.20–0.93 and CVD compared to the lowest quintile, and also a HR of 0.58 (95% CI 0.37–0.90 for the participants who ate at least 175 g/day of fruit. Only the participants in the highest quintile of fruit-derived fiber intake had a significantly lower risk of CVD (HR 0.52, 95% CI 0.28–0.97. The participants who ate at least one serving per week of cruciferous vegetables had a lower risk than those who did not (HR 0.52, 95% CI 0.30–0.89. In conclusion, high fruit consumption, whole grain consumption, or consumption of at least one serving/week of cruciferous vegetables may be protective against CVD in young Mediterranean populations.

To compare the types and quantities of carbohydrate, electrolytes, pH and osmolarity of fresh fruit juices and commercial fruit juices. Forty kinds of fresh fruits available in Thai markets were analyzed for types and quantities of carbohydrate, electrolyte, pH and osmolarity and compared with previously obtained data for commercial fruit juices. Most fresh fruit juices did not contain sucrose, whereas, commercial fruit juices mostly have sucrose in the range of 3-112 g/L. Although both fruit juices were acidic (pH varied from 3.6-6.7 and 3.2-5.8 of fresh juice and commercial juice), fresh fruit juices had a more neutral pH than commercial fruit juices. Apple, guava, orange, pear, and pineapple juices from commercial fruit juices had a high osmolarity compared with fresh fruit juices. All types of fresh fruit juices contained less sodium than commercial ones, whereas, most fresh fruit juices contained more potassium, phosphorus, and magnesium than commercial fluids. The nutrient content of fresh fruit juices and commercial fruit juices from the same kinds of fruits are not the same, possibly due to the manufacturing process. Therefore, physicians should know the composition of fruit juices in order to advise patients properly.

Carpenter, Belinda; Bond, Christine; Tait, Gordon; Wilson, Moira; White, Kris

2016-01-01

The objective of this study is to address the question: are those who leave suicide notes representative of the larger population of those who commit suicide? The method involves an analysis of a full population of suicides by residents of Queensland, Australia for the full year of 2004, with the information drawn from Coronial files. Our overall results suggest that, and in support of previous research, the population who leaves suicide notes are remarkably similar to those who do not. Differences are identified in four areas: first, and in contrast to prior research, females are less likely to leave a suicide note; second, and in support of previous research, Aboriginal Australians are less likely to leave suicide notes; third, and in support of some previous research, those who use gas as a method of suicide are more likely to leave notes, while those who use a vehicle or a train are less likely to leave notes; finally, our findings lend support to research which finds that those with a diagnosed mental illness are less likely to leave notes. The discussion addresses some of the reasons these disparities may have occurred, and continues the debate over the degree to which suicide notes give insight into the larger suicide population.

The association between alcohol availability, alcohol consumption and, in turn, alcohol-related harms is well established. Policies to reduce alcohol-related harms focus on limiting accessibility through the regulation of the liquor industry, including trading hours. On 1 July 2016, the Queensland Government introduced legislation to reduce ordinary liquor trading hours, replacing 5 am closing times with 3 am cessation of liquor sales in designated entertainment precincts and 2 am cessation of sales across the rest of the state. However, the amendment was under-inclusive and did not apply to temporary extended trading permits, a provision of the Liquor Act 1992 allowing one-off variations in trading hours for special events. We use 24 months of data (1 January 2015 to 31 December 2016) from the Office of Liquor Gaming and Regulation to explore patterns of extended trading permit use across Queensland, pre- and post- 1 July 2016. We find that following the Amendment in 2016 there was also a distinct shift in the utilisation of temporary extended trading permits, with a 63% increase in approved permits between 2015 and 2016. Temporal clustering around key calendar events dissipated following 1 July 2016 with consistent concentration of permit utilisation over consecutive weeks. Using temporary extended trading permits venue owners avoided earlier closing times and continued to operate until 5 am. The findings provide lessons for future policy implementation by illustrating the capacity for under-inclusive legislation to result in the dilution of intended effects. © 2018 Australasian Professional Society on Alcohol and other Drugs.

This paper reports on the evaluation of the Smart Choices healthy food and drink supply strategy for Queensland schools (Smart Choices) implementation across the whole school environment in state government primary and secondary schools in Queensland, Australia. Three concurrent surveys using different methods for each group of stakeholders that targeted all 1275 school Principals, all 1258 Parent and Citizens' Associations (P&Cs) and a random sample of 526 tuckshop convenors throughout Queensland. Nine hundred and seventy-three Principals, 598 P&Cs and 513 tuckshop convenors participated with response rates of 78%, 48% and 98%, respectively. Nearly all Principals (97%), P&Cs (99%) and tuckshop convenors (97%) reported that their school tuckshop had implemented Smart Choices. The majority of Principals and P&Cs reported implementation, respectively, in: school breakfast programs (98 and 92%); vending machine stock (94 and 83%); vending machine advertising (85 and 84%); school events (87 and 88%); school sporting events (81 and 80%); sponsorship and advertising (93 and 84%); fundraising events (80 and 84%); and sporting clubs (73 and 75%). Implementation in curriculum activities, classroom rewards and class parties was reported, respectively, by 97%, 86% and 75% of Principals. Respondents also reported very high levels of understanding of Smart Choices and engagement of the school community. The results demonstrated that food supply interventions to promote nutrition across all domains of the school environment can be implemented successfully.

Mate choice in fruit flies is rational and adaptive.

According to rational choice theory, beneficial preferences should lead individuals to sort available options into linear, transitive hierarchies, although the extent to which non-human animals behave rationally is unclear. Here we demonstrate that mate choice in the fruit fly Drosophila melanogaster results in the linear sorting of a set of diverse isogenic female lines, unambiguously demonstrating the hallmark of rational behaviour, transitivity. These rational choices are associated with direct benefits, enabling males to maximize offspring production. Furthermore, we demonstrate that female behaviours and cues act redundantly in mate detection and assessment, as rational mate choice largely persists when visual or chemical sensory modalities are impaired, but not when both are impaired. Transitivity in mate choice demonstrates that the quality of potential mates varies significantly among genotypes, and that males and females behave in such a way as to facilitate adaptive mate choice.

Across animals, sexual harassment induces fitness costs for females and males. However, little is known about the cognitive costs involved, i.e. whether it constrains learning processes, which could ultimately affect an individual's fitness. Here we evaluate the acquisition of environmental information in groups of fruit flies challenged with various levels of male sexual harassment. We show that, although high sexual harassment induces a temporary fitness cost for females, all fly groups of both sexes exhibit similar levels of learning. This suggests that, in fruit flies, the fitness benefits of acquiring environmental information are not affected by the fitness costs of sexual harassment, and that selection may favour cognition even in unfavourable social contexts. Our study provides novel insights into the relationship between sexual conflicts and cognition and the evolution of female counterstrategies against male sexual harassment. © 2016 The Author(s).

[Spectral navigation technology and its application in positioning the fruits of fruit trees].

Science.gov (United States)

Yu, Xiao-Lei; Zhao, Zhi-Min

2010-03-01

An innovative technology of spectral navigation is presented in the present paper. This new method adopts reflectance spectra of fruits, leaves and branches as one of the key navigation parameters and positions the fruits of fruit trees relying on the diversity of spectral characteristics. The research results show that the distinct smoothness as effect is available in the spectrum of leaves of fruit trees. On the other hand, gradual increasing as the trend is an important feature in the spectrum of branches of fruit trees while the spectrum of fruit fluctuates. In addition, the peak diversity of reflectance rate between fruits and leaves of fruit trees is reached at 850 nm of wavelength. So the limit value can be designed at this wavelength in order to distinguish fruits and leaves. The method introduced here can not only quickly distinguish fruits, leaves and branches, but also avoid the effects of surroundings. Compared with the traditional navigation systems based on machine vision, there are still some special and unique features in the field of positioning the fruits of fruit trees using spectral navigation technology.

Full Text Available Abstract Background Patterns of diagnosis and management for men diagnosed with prostate cancer in Queensland, Australia, have not yet been systematically documented and so assumptions of equity are untested. This longitudinal study investigates the association between prostate cancer diagnostic and treatment outcomes and key area-level characteristics and individual-level demographic, clinical and psychosocial factors. Methods/Design A total of 1064 men diagnosed with prostate cancer between February 2005 and July 2007 were recruited through hospital-based urology outpatient clinics and private practices in the centres of Brisbane, Townsville and Mackay (82% of those referred. Additional clinical and diagnostic information for all 6609 men diagnosed with prostate cancer in Queensland during the study period was obtained via the population-based Queensland Cancer Registry. Respondent data are collected using telephone and self-administered questionnaires at pre-treatment and at 2 months, 6 months, 12 months, 24 months, 36 months, 48 months and 60 months post-treatment. Assessments include demographics, medical history, patterns of care, disease and treatment characteristics together with outcomes associated with prostate cancer, as well as information about quality of life and psychological adjustment. Complementary detailed treatment information is abstracted from participants' medical records held in hospitals and private treatment facilities and collated with health service utilisation data obtained from Medicare Australia. Information about the characteristics of geographical areas is being obtained from data custodians such as the Australian Bureau of Statistics. Geo-coding and spatial technology will be used to calculate road travel distances from patients' residences to treatment centres. Analyses will be conducted using standard statistical methods along with multilevel regression models including individual and area-level components

The role of integrative taxonomy in the conservation management of cryptic species: the taxonomic status of endangered earless dragons (Agamidae: Tympanocryptis in the grasslands of Queensland, Australia.

Full Text Available Molecular phylogenetics is increasingly highlighting the prevalence of cryptic species, where morphologically similar organisms have long independent evolutionary histories. When such cryptic species are known to be declining in numbers and are at risk of extinction due to a range of threatening processes, the disjunction between molecular systematics research and conservation policy becomes a significant problem. We investigate the taxonomic status of Tympanocryptis populations in Queensland, which have previously been assigned to T. tetraporophora, using three species delimitation approaches. The taxonomic uncertainties in this species-group are of particular importance in the Darling Downs Earless Dragon (T. cf. tetraporophora, which is ranked as an endangered 'species' of high priority for conservation by the Queensland Department of Environment and Heritage Protection. We undertook a morphological study, integrated with a comprehensive genetic study and species delimitation analyses, to investigate the species status of populations in the region. Phylogenetic analyses of two gene regions (mtDNA: ND2; nuclear: RAG1 revealed high levels of genetic divergence between populations, indicating isolation over long evolutionary time frames, and strongly supporting two independent evolutionary lineages in southeastern Queensland, from the Darling Downs, and a third in the Gulf Region of northern Queensland. Of the three species delimitation protocols used, we found integrative taxonomy the most applicable to this cryptic species complex. Our study demonstrates the utility of integrative taxonomy as a species delimitation approach in cryptic complexes of species with conservation significance, where limited numbers of specimens are available.

Full Text Available ABSTRACT Pineapple fruit collapse: newly emerging disease of pineapple fruit in Lampung, Indonesia Recently, a new disease on pineapple fruit has occurred in Lampung. Symptoms of the disease are complex. Fruits rotted and exuded copious liquid from the inter- fruitlet tissues accompanied by gas bubbles. Open spaces were formed inside the rotten fruit. Dissection of diseased fruit showed many cavities within its sceletal fibres and bad odour was exerted from the rotten tissues. A bacterial entity was isolated  from the diseased materials. In a pathogenicity test, the isolated bacteria caused the same symptom as mentioned. In the growing-on test the crown of the heavily infected fruit  showed  heart rot symptom.  Those  indicated that the disease was pineapple fruit collapse. Both symptoms were known related to the same causal agent, Erwinia chrysanthemi (pineapple strain Dickeya sp.. In our opinion, this is the first report of pineapple fruit collapse in Indonesia.

Genetically modified parthenocarpic eggplants: improved fruit productivity under both greenhouse and open field cultivation.

2002-04-01

Full Text Available Abstract Background Parthenocarpy, or fruit development in the absence of fertilization, has been genetically engineered in eggplant and in other horticultural species by using the DefH9-iaaM gene. The iaaM gene codes for tryptophan monoxygenase and confers auxin synthesis, while the DefH9 controlling regions drive expression of the gene specifically in the ovules and placenta. A previous greenhouse trial for winter production of genetically engineered (GM parthenocarpic eggplants demonstrated a significant increase (an average of 33% increase in fruit production concomitant with a reduction in cultivation costs. Results GM parthenocarpic eggplants have been evaluated in three field trials. Two greenhouse spring trials have shown that these plants outyielded the corresponding untransformed genotypes, while a summer trial has shown that improved fruit productivity in GM eggplants can also be achieved in open field cultivation. Since the fruits were always seedless, the quality of GM eggplant fruits was improved as well. RT-PCR analysis demonstrated that the DefH9-iaaM gene is expressed during late stages of fruit development. Conclusions The DefH9-iaaM parthenocarpic gene is a biotechnological tool that enhances the agronomic value of all eggplant genotypes tested. The main advantages of DefH9-iaaM eggplants are: i improved fruit productivity (at least 30–35% under both greenhouse and open field cultivation; ii production of good quality (marketable fruits during different types of cultivation; iii seedless fruit with improved quality. Such advantages have been achieved without the use of either male or female sterility genes.

1998-01-01

This study was carried out since 1990 to 1997. The goal was to figure out different species of fruit fly that inhabit in Ecuador. For the identification we put special emphasis in the female genitalia. We recommend to do more research into this subject, because of the few studies done in our country and the importance of fruit cultivation. We mention 32 genus in the family Tephritidae in Ecuador, including the introduced genus Ceratitis. Into Toxotrypaninae are pointing out the presence of one specie of the Toxotrypana genus and 31 species of the Anastrepha genus, detailing brilly the 27 species most common. General notions about taxonomic bases are mentioned in order to identify species of the Anastrepha Schiner, pointing out certain fenotipic characteristics that prove variability among the ecuadorian's population, mainly A. fraterculus, A. distincta, A. obliqua, A. striata, and others.

Full Text Available Influence of different tropical fruits on biological and behavioral aspects of the Mediterranean fruit fly Ceratitis capitata (Wiedemann (Diptera, Tephritidae. Studies on Ceratitis capitata, a world fruit pest, can aid the implementation of control programs by determining the plants with higher vulnerability to attacks and plants able to sustain their population in areas of fly distribution. The objective of the present study was to evaluate the influence of eight tropical fruits on the following biological and behavioral parameters of C. capitata: emergence percentage, life cycle duration, adult size, egg production, longevity, fecundity, egg viability, and oviposition acceptance. The fruits tested were: acerola (Malpighia glabra L., cashew (Anacardium occidentale L., star fruit (Averrhoa carambola L., guava (Psidium guajava L., soursop (Annona muricata L., yellow mombin (Spondias mombin L., Malay apple (Syzygium malaccense L., and umbu (Spondias tuberosa L.. The biological parameters were obtained by rearing the recently hatched larvae on each of the fruit kinds. Acceptance of fruits for oviposition experiment was assessed using no-choice tests, as couples were exposed to two pieces of the same fruit. The best performances were obtained with guava, soursop, and star fruit. Larvae reared on cashew and acerola fruits had regular performances. No adults emerged from yellow mombin, Malay apple, or umbu. Fruit species did not affect adult longevity, female fecundity, or egg viability. Guava, soursop, and acerola were preferred for oviposition, followed by star fruit, Malay apple, cashew, and yellow mombin. Oviposition did not occur on umbu. In general, fruits with better larval development were also more accepted for oviposition.Influência de diferentes frutos tropicais em aspectos biológicos e comportamentais da mosca-das-frutas Ceratitis capitata (Wiedemann (Diptera, Tephritidae.

Watson, Barry; Freeman, James

2007-03-01

The present study explored the impact of random breath testing (RBT) on the attitudes, perceptions, and self-reported behavior of motorists in the Australian state of Queensland. Particular attention was given to how exposure to RBT impacted motorists' perceived risk of apprehension and self-reported behavior, relative to other variables of interest such as alcohol consumption. The study involved a telephone survey of 780 motorists drawn from throughout the state of Queensland. Participants were volunteers recruited from a random sample of all listed telephone numbers in the state, adjusted according to district population figures. The survey questionnaire collected information relating to the participants' socio-demographic characteristics, drinking and drunk driving behaviors, attitudes toward drunk driving and RBT, and experiences and perceptions of RBT. The analysis indicated that a large proportion of the sample had both observed RBT and been breath tested within the last six months and believed the practice served an important role in improving road safety. However, a considerable percentage also reported drunk driving at least once in the last six months without being detected, with further analysis indicating that the threat of apprehension associated with RBT did not appear to greatly influence their offending behavior. Rather, a higher frequency of alcohol consumption, combined with more favorable attitudes to drunk driving and lower levels of support for RBT, appeared to be associated with offending behavior. While the results confirm the high levels of exposure to RBT achieved in Queensland, the direct impact of recent exposure on drunk driving behavior appears less important than other factors such as alcohol consumption and attitudes to drunk driving and RBT. Further research is required to better understand how recent and lifetime exposure to RBT impacts on motorists' perceived risk of apprehension and subsequent drunk driving behavior.

The survival inequality faced by Indigenous Australians after a cancer diagnosis is well documented; what is less understood is whether this inequality has changed over time and what this means in terms of the impact a cancer diagnosis has on Indigenous people. Survival information for all patients identified as either Indigenous (n=3168) or non-Indigenous (n=211,615) and diagnosed in Queensland between 1997 and 2012 were obtained from the Queensland Cancer Registry, with mortality followed up to 31st December, 2013. Flexible parametric survival models were used to quantify changes in the cause-specific survival inequalities and the number of lives that might be saved if these inequalities were removed. Among Indigenous cancer patients, the 5-year cause-specific survival (adjusted by age, sex and broad cancer type) increased from 52.9% in 1997-2006 to 58.6% in 2007-2012, while it improved from 61.0% to 64.9% among non-Indigenous patients. This meant that the adjusted 5-year comparative survival ratio (Indigenous: non-Indigenous) increased from 0.87 [0.83-0.88] to 0.89 [0.87-0.93], with similar improvements in the 1-year comparative survival. Using a simulated cohort corresponding to the number and age-distribution of Indigenous people diagnosed with cancer in Queensland each year (n=300), based on the 1997-2006 cohort mortality rates, 35 of the 170 deaths due to cancer (21%) expected within five years of diagnosis were due to the Indigenous: non-Indigenous survival inequality. This percentage was similar when applying 2007-2012 cohort mortality rates (19%; 27 out of 140 deaths). Indigenous people diagnosed with cancer still face a poorer survival outlook than their non-Indigenous counterparts, particularly in the first year after diagnosis. The improving survival outcomes among both Indigenous and non-Indigenous cancer patients, and the decreasing absolute impact of the Indigenous survival disadvantage, should provide increased motivation to continue and enhance

Potential exposure to Australian bat lyssavirus is unlikely to prevent future bat handling among adults in South East Queensland.

Despite ongoing public health messages about the risks associated with bat contact, the number of potential exposures to Australian bat lyssavirus (ABLV) due to intentional handling by members of the general public in Queensland has remained high. We sought to better understand the reasons for intentional handling among these members of the public who reported their potential exposure to inform future public health messages. We interviewed adults who resided in a defined geographic area in South East Queensland and notified potential exposure to ABLV due to intentional handling of bats by telephone between 1 January 2012 and 31 December 2013. The participation rate was 54%. Adults who reported they had intentionally handled bats in South East Queensland indicated high levels of knowledge and perception of a moderately high risk associated with bats with overall low intentions to handle bats in the future. However, substantial proportions of people would attempt to handle bats again in some circumstances, particularly to protect their children or pets. Fifty-two percent indicated that they would handle a bat if a child was about to pick up or touch a live bat, and 49% would intervene if a pet was interacting with a bat. Future public health communications should recognize the situations in which even people with highrisk perceptions of bats will attempt to handle them. Public health messages currently focus on avoidance of bats in all circumstances and recommend calling in a trained vaccinated handler, but messaging directed at adults for circumstances where children or pets may be potentially exposed should provide safe immediate management options. © 2017 Blackwell Verlag GmbH.

Lifestyle factors affecting fruit and vegetable consumption in the UK Women's Cohort Study.

Pollard, J; Greenwood, D; Kirk, S; Cade, J

2001-08-01

The UK Women's Cohort Study (UKWCS) was originally set up to look at morbidity and mortality data on subjects with a wide range of dietary intakes including vegans, lacto-ovo vegetarians, non-red meat eaters and red meat eaters. The aim of the present study was to investigate factors that affect fruit and vegetable consumption within this particular cohort of women. Females of ages 35-69 years, taking part in the UK Women's Cohort Study (N=35 367), provided health and lifestyle information including a 217-item food frequency questionnaire. In multiple logistic regression, the strongest predictors of a higher reported level of fruit and vegetable consumption were being a vegetarian or vegan, taking vitamin or mineral supplements, being married, educated to A-level or degree level and belonging to a higher socio-economic group. Conversely, smokers were found to be only half as likely as non-smokers to be high fruit and vegetable consumers. These lifestyle distinctions among three levels of reported fruit and vegetable consumption are relevant to the future targeting of health promotion strategies. Copyright 2000 Academic Press.

Since 2008 APHIS/USDA approved to import dragon fruit into the United States from Vietnam if fruits are treated with the minimum absorbed dose of 400 Gy to control fruit flies and mealybugs. However, a lower dose could be accepted if released data is enough to demonstrate that it is efficient to inhibit the development and stop the reproduction of adult females for three species of mealybugs (Order: Hemiptera; Family: Pseudococcidae) infesting on dragon fruit. Four development stages including 1 st , 2 nd , 3 rd instars and adult of Dymicoccus neobrevipes by isolating and rearing in the laboratory conditions were irradiated in Co-60 source gamma with dosages of 100, 200, 300 and 400 Gy. The main purposes of the study are to find the most tolerant stage and to determine the most optimal dose to control D. neobrevipes. The initial obtained results showed that the adult stage is the most radiotolerant and the dose of 200 Gy could be an effective dose to inhibit development and to control reproduction of D. neobrevipes.

Development of Bait Stations for Fruit Fly Suppression in Support of SIT. Working Material

International Nuclear Information System (INIS)

2009-01-01

A more economic and practical fruit fly suppression tool is needed to replace conventional aerial and ground bait sprays applications over human settlements, protected natural areas, and difficult to access areas where fruit fly hosts exist. This has been a major request from area-wide integrated pest management action programmes using the Sterile Insect Technique (SIT) as a component. In recent years, especially in Europe, most conventional insecticides used to control fruit pests have been banned (e.g. malathion, dichlorvos and other organophosphates), therefore areas producing fruits and vegetables for markets that request low insecticide residues or even fruit and vegetable organic farming is seeking for a more economic fruit fly control option to the spinosad-based bait sprays and to the use of mass trapping. To address these requests, bait stations can be one of the most suitable alternatives. The development of these devices needs to take into consideration cost-effectiveness, and long lasting attractants and killing agents, and should target female fruit flies. Recent developments of synthetic food attractants and long-lasting formulations open the possibility to improve the existent baits stations or develop new ones. With this objective the Insect Pest Control Subprogramme of the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture organized a Consultants Meeting ('Development of Bait Stations for Fruit Fly Suppression in Support of SIT'), held in Mazatlan, Mexico, from 30 October to 1 November 2008, with the participation of 14 scientists from the Instituto Nacional de Tecnologia Agropecuaria, Argentina; Department of Primary Industries and Fisheries, Australia; North American Plant Protection Organization, Canada; African Insect Science for Food and Health, Kenya; Universidad Politecnica de Valencia, Spain; Institut de Recerca i Tecnologia Agroalimentaries, Spain, Secretaria de Agricultura, Ganaderia, Desarrollo Rural, Pesca y

Although it is known that ethylene has a masculinizing effect on watermelon, the specific role of this hormone in sex expression and flower development has not been analyzed in depth. By using different approaches the present work demonstrates that ethylene regulates differentially two sex-related developmental processes: sexual expression, i.e. the earliness and the number of female flowers per plant, and the development of individual floral buds. Ethylene production in the shoot apex as well as in male, female and bisexual flowers demonstrated that the female flower requires much more ethylene than the male one to develop, and that bisexual flowers result from a decrease in ethylene production in the female floral bud. The occurrence of bisexual flowers was found to be associated with elevated temperatures in the greenhouse, concomitantly with a reduction of ethylene production in the shoot apex. External treatments with ethephon and AVG, and the use of Cucurbita rootstocks with different ethylene production and sensitivity, confirmed that, as occurs in other cucurbit species, ethylene is required to arrest the development of stamens in the female flower. Nevertheless, in watermelon ethylene inhibits the transition from male to female flowering and reduces the number of pistillate flowers per plant, which runs contrary to findings in other cucurbit species. The use of Cucurbita rootstocks with elevated ethylene production delayed the production of female flowers but reduced the number of bisexual flowers, which is associated with a reduced fruit set and altered fruit shape.

The biology of olive fruit fly, Bactrocera oleae (Rossi), was studied in the laboratory, greenhouse, and in canning olives, Olea europaea L., in relation to California regional climates. Adults survived in laboratory tests at constant temperatures and relative humidities of 5 degrees C and 83%; 15 degrees C and 59%; 25 degrees C and 30%; and 35 degrees C and 29% for 15, 6, 3, and 2 d without provisions of food and water and for 37, 63, 25, and 4 d with provisions, respectively. In a divided greenhouse, adults survived for 8-11 d in the warm side (36 degrees C and 31% RH daytime); and in the cool side (26 degrees C and 63% RH daytime) 10 d without provisions and 203 d with provisions. A significantly greater number of adults survived in the cool side than the warm side, and with provisions than without. First and last eggs were oviposited in olive fruit when females were 6 and 90 d old, respectively. The highest number of eggs was 55 per day in 10 olive fruit oviposited by 10 28 d-old females, with maximum egg production by 13-37 d-old females. A significantly greater number of ovipositional sites occurred in all sizes of immature green fruit when exposed to adults in cages for 5 d than 2 d. Adults emerged from fruit with a height of > or = 1.0 cm or a volume of > or = 0.2 cm3. More than seven adults per 15 fruit emerged from field infested fruit with a height of 1.1 cm and volume of 0.1 cm3. Larval length was significantly different among the first, second, and third instars and ranged from 0.7 to 1.6, 2.4-4.3, and 4.8-5.6 mm at 14 degrees C; 0.8-1.1, 1.9-2.9, and 3.9-4.4 mm at 21 degrees C, and 0.7-1.3, 2.4-2.9, and 4.4-4.8 mm at 26 degrees C, respectively. Survival of pupae to the adult stage was significantly lower at 26 degrees C than 14 degrees C or 21 degrees C. The period of adult emergence began at 38, 14, and 11 d over a period of 8, 5, and 1 d at 14, 21, and 26 degrees C, respectively. Findings were related to the occurrence and control of California

Warfarin is widely prescribed to decrease the risk of stroke in atrial fibrillation (AF) patients. Due to patient variability in response, regular monitoring is required, and time in therapeutic range (TTR) used to indicate quality of warfarin control with a TTR>60% is recommended. Recently, an Australian Government review of anticoagulants identified the need to establish current warfarin control and determine the potential place of the newer oral anticoagulants. To determine warfarin control by a pathology practice in Queensland, Australia and identify factors influencing TTR. Retrospective data were collected from Sullivan Nicolaides Pathology, a major pathology practice offering a warfarin care programme in Australia. Patients enrolled in their programme as of September 2014 were included in the study. TTR was calculated using INR test results, and test dates using the Rosendaal method with mean patient TTR were used for analysis and comparison. Exclusions were target therapeutic range outside 2.0-3.0, less than two INR tests and programme treatment time of less than 30 days. The eligible 3692 AF patients had 73.6% of INR tests within the therapeutic range. The mean TTR was 81%, with 97% of patients above a TTR of 60%. TTR was not significantly influenced by age, gender or socioeconomic factors. The observed mean TTR of over 80% is superior to the minimum recommended threshold of 60%. The TTR achieved by the Queensland pathology practice demonstrates that dedicated warfarin programmes can produce high-quality warfarin care, ensuring the full benefit of warfarin for Australian patients. © 2016 Royal Australasian College of Physicians.

Relatively little is known about the nutritional ecology of fruit flies in the genus Rhagoletis. In this study, nutrient amounts in male and female western cherry fruit fly, Rhagoletis indifferens Curran, and availability of nitrogen and sugar on surfaces of leaves, fruit, and extrafloral nectaries (EFNs) of sweet cherry trees, were determined from late May to late June 2005 and of sugar from EFNs from mid-May to late June 2007 in Washington state. Protein amounts in male and female flies did not differ over the season. Nitrogen was present on leaves, fruit, and EFNs during the sampling period, but amounts on leaves and fruit were lower in late May than the rest of the season. Sugar amounts in flies did not differ over the season. Sugar was present on leaf, fruit, and EFN surfaces all season, but amounts on all three were lower in late May than later in the season. Fructose and glucose were the predominant sugars on all plant surfaces, but sucrose was also present in nectar from EFNs. In outdoor and field cage experiments in 2004 and 2006, more flies survived when cherry branches with leaves and fruit were present than absent. Results suggest that R. indifferens maintains stable protein and sugar levels throughout the season because sufficient amounts of nutrients are found in cherry trees during this time and that increases in nutrient availability caused by ripening and damaged cherries later in the season do not result in increased amounts of nutrients in flies.

To develop an open, self-reported questionnaire, focused in understanding intake and intention to increase vegetable and fruit consumption during the Mexican children's lunchtime. After assessing pilot tests, the self-reported questionnaire was applied as a classroom exercise to measure children's consumptions of fruit and vegetables. A total of 486 children completed the questionnaire (49.8% males and 50.2% females). The reported food consumption indicates that 24.5% of children do not consume vegetables or fruits, and among consumers the most common portion size is one. Girls consume more vegetables and fruits and they can recognize more benefits. A total of 9.7% of the participants that do not consume VF, expressed less intention of including vegetables or fruits in their lunch. These results were similar to those reported by other authors. This study is useful to identify strengths and limitations during the design and implementation of this type of instrument to understand children's food habits during school recess.

Although polygamy is common in insects, its extent varies enormously among natural populations. Mating systems influence the evolution of reproductive traits and the difference in extent of polygamy between males and females may be a key factor in determining traits which come under the influence of sexual selection. Fruit flies Drosophila melanogaster are promiscuous as both males and females mate with multiple partners. Mating has severe consequences on the physiology and behaviour of flies, and it affects their activity/rest rhythm in a sex-specific manner. In this study, we attempted to discern the effects of mating with multiple partners as opposed to a single partner, or of remaining unmated, on the activity/rest rhythm of flies under cyclic semi-natural (SN) and constant dark (DD) conditions. The results revealed that while evening activity of mated flies was significantly reduced compared to virgins, polygamous males showed a more severe reduction compared to monogamous males. In contrast, though mated females showed reduction in evening activity compared to virgins, activity levels were not different between polygamous and monogamous females. Although there was no detectable effect of mating on clock period, power of the activity/rest rhythm was significantly reduced in mated females with no difference seen between polygamous and monogamous individuals. These results suggest that courtship motivation, represented by evening activity, is successively reduced in males due to mating with one or more partners, while in females, it does not depend on the number of mating partners. Based on these results we conclude that polygamy affects the activity/rest rhythm of fruit flies D. melanogaster in a sex-dependent manner.

Mercury, an environmental health hazard, is a neurotoxic heavy metal. In this study, the effect of methylmercury (MeHg) exposure was analyzed on sexual behavior in Drosophila melanogaster (fruit fly), because neurons play a vital role in sexual functions. The virgin male and female flies were fed a diet mixed with different concentrations of MeHg (28.25, 56.5, 113, 226, and 339 µM) for four days, and the effect of MeHg on copulation of these flies was studied. While male and female control flies (no MeHg) and flies fed with lower concentrations of MeHg (28.25, 56.5 µM) copulated in a normal manner, male and female flies exposed to higher concentrations of MeHg (113, 226, and 339 µM) did not copulate. When male flies exposed to higher concentrations of MeHg were allowed to copulate with control female flies, only male flies fed with 113 µM MeHg were able to copulate. On the other hand, when female flies exposed to higher concentrations of MeHg were allowed to copulate with control male flies, none of the flies could copulate. After introduction of male and female flies in the copulation chamber, duration of wing flapping by male flies decreased in a MeHg-concentration-dependent manner from 101 ± 24 seconds (control) to 100.7 ± 18, 96 ±12, 59 ± 44, 31 ± 15, and 3.7 ± 2.7 seconds at 28.25, 56.5, 113, 226, and 339 µM MeHg, respectively. On the other hand, grooming in male and female flies increased in a MeHg-concentration-dependent manner. These findings suggest that MeHg exposure causes sexual dysfunction in male and female Drosophila melanogaster . Further studies showed that MeHg exposure increased oxidative stress and decreased triglyceride levels in a concentration-dependent manner in both male and female flies, suggesting that MeHg-induced oxidative stress and decreased triglyceride levels may partly contribute to sexual dysfunction in fruit flies.

Cutaneous malignant melanoma (CMM) is a major health issue in Queensland, Australia which has the world’s highest incidence. Recent molecular and epidemiologic studies suggest that CMM arises through multiple etiological pathways involving gene-environment interactions. Understanding the potential mechanisms leading to CMM requires larger studies than those previously conducted. This article describes the design and baseline characteristics of Q-MEGA, the Queensland study of Melanoma: Environmental and Genetic Associations, which followed-up four population-based samples of CMM patients in Queensland, including children, adolescents, men aged over 50, and a large sample of adult cases and their families, including twins. Q-MEGA aims to investigate the roles of genetic and environmental factors, and their interaction, in the etiology of melanoma. 3,471 participants took part in the follow-up study and were administered a computer-assisted telephone interview in 2002–2005. Updated data on environmental and phenotypic risk factors, and 2,777 blood samples were collected from interviewed participants as well as a subset of relatives. This study provides a large and well-described population-based sample of CMM cases with follow-up data. Characteristics of the cases and repeatability of sun exposure and phenotype measures between the baseline and the follow-up surveys, from six to 17 years later, are also described. PMID:18361720

Initiatives to promote utility cycling in countries like Australia and the US, which have low rates of utility cycling, may be more effective if they first target recreational cyclists. This study aimed to describe patterns of utility cycling and examine its correlates, among cyclists in Queensland, Australia. An online survey was administered to adult members of a state-based cycling community and advocacy group (n=1813). The survey asked about demographic characteristics and cycling behavior, motivators and constraints. Utility cycling patterns were described, and logistic regression modeling was used to examine associations between utility cycling and other variables. Forty-seven percent of respondents reported utility cycling: most did so to commute (86%). Most journeys (83%) were >5 km. Being male, younger, employed full-time, or university-educated increased the likelihood of utility cycling (P<.05). Perceiving cycling to be a cheap or a convenient form of transport was associated with utility cycling (P<.05). The moderate rate of utility cycling among recreational cyclists highlights a potential to promote utility cycling among this group. To increase utility cycling, strategies should target female and older recreational cyclists and focus on making cycling a cheap and convenient mode of transport.

Little is known about the threat of mercury (Hg) to consumers in food webs of Australia's wet–dry tropics. This is despite high concentrations in similar biomes elsewhere and a recent history of gold mining that could lead to a high degree of exposure for biota. We analysed Hg in water, sediments, invertebrates and fishes in rivers and estuaries of north Queensland, Australia to determine its availability and biomagnification in food webs. Concentrations in water and sediments were low relative to other regions of Hg concern, with only four of 138 water samples and five of 60 sediment samples above detection limits of 0.1 μg L −1 and 0.1 μg g −1 , respectively. Concentrations of Hg in fishes and invertebrates from riverine and wetland food webs were well below international consumption guidelines, including those in piscivorous fishes, likely due to low baseline concentrations and limited rates of biomagnification (average slope of log Hg vs. δ 15 N = 0.08). A large fish species of recreational, commercial, and cultural importance (the barramundi, Lates calcarifer), had low concentrations that were below consumption guidelines. Observed variation in Hg concentrations in this species was primarily explained by age and foraging location (floodplain vs. coastal), with floodplain feeders having higher Hg concentrations than those foraging at sea. These analyses suggest that there is a limited threat of Hg exposure for fish-eating consumers in this region. - Highlights: ► Hg concentrations in freshwaters and sediments of north Queensland were low. ► Biomagnification of Hg through riverine food webs was limited. ► Barramundi, a predatory fish, had low concentrations meaning low risk for consumers. ► Floodplain-feeding barramundi had higher Hg concentrations than coastal feeders.

To conduct a cost analysis of a telemedicine model for cancer care (teleoncology) in northern Queensland, Australia, compared with the usual model of care from the perspective of the Townsville and other participating hospital and health services. Retrospective cost-savings analysis; and a one-way sensitivity analysis performed to test the robustness of findings in net savings. Records of all patients managed by means of teleoncology at the Townsville Cancer Centre (TCC) and its six rural satellite centres in northern Queensland, Australia between 1 March 2007 and 30 November 2011. Costs for set-up and staffing to manage the service, and savings from avoidance of travel expenses for specialist oncologists, patients and their escorts, and for aeromedical retrievals. There were 605 teleoncology consultations with 147 patients over 56 months, at a total cost of $442 276. The cost for project establishment was $36 000, equipment/maintenance was $143 271, and staff was $261 520. The estimated travel expense avoided was $762 394; this figure included the costs of travel for patients and escorts of $658 760, aeromedical retrievals of $52 400 and travel for specialists of $47 634, as well as an estimate of accommodation costs for a proportion of patients of $3600. This resulted in a net saving of $320 118. Costs would have to increase by 72% to negate the savings. The teleoncology model of care at the TCC resulted in net savings, mainly due to avoidance of travel costs. Such savings could be redirected to enhancing rural resources and service capabilities. This teleoncology model is applicable to geographically distant areas requiring lengthy travel.

Full Text Available The study was carried out to evaluate acute and subchronic toxicities of the water extract from the dried fruits of Piper nigrum L. A single oral administration of the extract at a dose of 5,000 mg/kg body weight (5 male, 5 female did not produce signs of toxicity, behavioral changes, mortality, changes on gross appearance or histopathological changes of internal organs. The subchronic toxicity was determined by oral feeding both male and female rats (10 male, 10 female daily with the test substance at the doses of 300, 600 and 1,200 mg/kg body weight continuously for 90 days. The examinations of signs, animal behavior and health monitoring showed no abnormalities in the test groups as compared to the controls. The test and control groups (on the 90th day and the satellite group (on the 118th day were analyzed by measuring their final body and organ weights, taking necropsy, and examining hematology, blood clinical chemistry and histopathology. The results suggest that the water extract from the dried fruits of P. nigrum does not cause acute or subchronic toxicities in either male or female rats.

The current work was conducted in order to determine the level of oviposition of Anastrepha fraterculus on fresh mangos and artificial oviposition devices. Four trials were carried out during which freshly harvested fruit was exposed to wild South American adult fruit flies. The following viable oviposition/day/kg of fruit (viable ovipositions = emerged adults) were established: 79.16, 71.25, 83.6 and 60.6. The trials were carried out at 25 deg. C - 28 deg. C and 60%-80% relative humidity. Beginning with the first generation one trial was carried out which confirmed the acceptance of sexually mature females to oviposit on red oviposition devices consisting of wax-covered cloth. However, red plastic containers with holes of 0.5 mm did not produce good results. (author)

Fruiting structures in the angiosperms range from completely dry to highly fleshy organs and provide many of our major crop products, including grains. In the model plant Arabidopsis, which has dry fruits, a high-level regulatory network of transcription factors controlling fruit development has been revealed. Studies on rare nonripening mutations in tomato, a model for fleshy fruits, have provided new insights into the networks responsible for the control of ripening. It is apparent that there are strong similarities between dry and fleshy fruits in the molecular circuits governing development and maturation. Translation of information from tomato to other fleshy-fruited species indicates that regulatory networks are conserved across a wide spectrum of angiosperm fruit morphologies. Fruits are an essential part of the human diet, and recent developments in the sequencing of angiosperm genomes have provided the foundation for a step change in crop improvement through the understanding and harnessing of genome-wide genetic and epigenetic variation.

Towards Distributed Citizen Participation: Lessons from WikiLeaks and the Queensland Floods

Full Text Available This paper examines the rapid and ad hoc development and interactions of participative citizen communities during acute events, using the examples of the 2011 floods in Queensland, Australia, and the global controversy surrounding Wikileaks and its spokesman, Julian Assange. The self-organising community responses to such events which can be observed in these cases bypass or leapfrog, at least temporarily, most organisational or administrative hurdles which may otherwise frustrate the establishment of online communities; they fast-track the processes of community development and structuration. By understanding them as a form of rapid prototyping, e-democracy initiatives can draw important lessons from observing the community activities around such acute events.

The lifetime erythemal UV exposures received by selected population groups in south-east Queensland from birth up to an age of 55 years have been quantitatively estimated. A representative sample of teachers and other school workers received (64±22)x10 5 J m -2 to the neck compared with (4.1±1.4)x10 5 Jm -2 to the upper leg. A sample of indoor workers (bank officers, solicitors and psychologists) received approximately 2% less and a sample of outdoor workers (carpenters, tilers, electricians and labourers) received approximately 10% more to the neck than the school workers. These differences in erythemal UV exposures may influence the risk of non-melanoma skin cancer. (author)

2014-01-01

To explore the predictability of radiocaesium concentration in the mature peach fruits based on the radiocaesium concentration in the young superfluous fruits picked at the fruit thinning period, the change in the radiocaesium concentration as well as potassium ("4"0K) in peach fruits associated with fruit growth was monitored during the second year after the accident of the nuclear power plant in Fukushima. Radiocaesium concentration was found to be highest in the fruit 15 days after the full bloom stage, followed by the gradual decrease before harvest. In addition, variation of radiocaesium and "4"0K concentration with time was shown to be different in leaves and fruits. Finally, the young fruits 60 days after the full bloom date and the ripe fruits were taken from 24 orchards in Fukushima to compare their radiocaesium levels. The predictability of radiocaesium concentration and some considerations for practical use are discussed. (author)

Testing hypotheses for excess flower production and low fruit-to-flower ratios in a pollinating seed-consuming mutualism

2004-01-01

Pollinator attraction, pollen limitation, resource limitation, pollen donation and selective fruit abortion have all been proposed as processes explaining why hermaphroditic plants commonly produce many more flowers than mature fruit. We conducted a series of experiments in Arizona to investigate low fruit-to-flower ratios in senita cacti, which rely exclusively on pollinating seed-consumers. Selective abortion of fruit based on seed predators is of particular interest in this case because plants relying on pollinating seed-consumers are predicted to have such a mechanism to minimize seed loss. Pollinator attraction and pollen dispersal increased with flower number, but fruit set did not, refuting the hypothesis that excess flowers increase fruit set by attracting more pollinators. Fruit set of natural- and hand-pollinated flowers were not different, supporting the resource, rather than pollen, limitation hypothesis. Senita did abort fruit, but not selectively based on pollen quantity, pollen donors, or seed predators. Collectively, these results are consistent with sex allocation theory in that resource allocation to excess flower production can increase pollen dispersal and the male fitness function of flowers, but consequently results in reduced resources available for fruit set. Inconsistent with sex allocation theory, however, fruit production and the female fitness function of flowers may actually increase with flower production. This is because excess flower production lowers pollinator-to-flower ratios and results in fruit abortion, both of which limit the abundance and hence oviposition rates, of pre-dispersal seed predators.

Quarantine treatment enables export of avocado fruit (Persea americana) to parts of the world that enforce quarantine against fruit fly. The recommended cold-based quarantine treatment (storage at 1.1°C for 14 days) was studied with two commercial avocado cultivars 'Hass' and 'Ettinger' for 2 years. Chilling injuries (CIs) are prevalent in the avocado fruit after cold-quarantine treatment. Hence, we examined the effect of integrating several treatments: modified atmosphere (MA; fruit covered with perforated polyethylene bags), methyl jasmonate (MJ; fruit dipped in 2.5 μM MJ for Hass or 10 μM MJ for Ettinger for 30 s), 1-methylcyclopropene (1-MCP; fruit treated with 300 ppb 1-MCP for 18 h) and low-temperature conditioning (LTC; a gradual decrease in temperature over 3 days) on CI reduction during cold quarantine. Avocado fruit stored at 1°C suffered from severe CI, lipid peroxidation, and increased expression of chilling-responsive genes of fruit peel. The combined therapeutic treatments alleviated CI in cold-quarantined fruit to the level in fruit stored at commercial temperature (5°C). A successful therapeutic treatment was developed to protect 'Hass' and 'Ettinger' avocado fruit during cold quarantine against fruit fly, while maintaining fruit quality. Subsequently, treated fruit stored at 1°C had a longer shelf life and less decay than the fruit stored at 5°C. This therapeutic treatment could potentially enable the export of avocado fruit to all quarantine-enforcing countries. Similar methods might be applicable to other types of fruit that require cold quarantine.

Dispersal and survival of sterile male (TSL strain) Mediterranean fruit flies

Barbosa, S.; Mexia, A.; Pereira, R.

2000-01-01

The Mediterranean fruit fly, Ceratitis capitata (Weid.), is a major pest of fruit in the Portuguese Autonomous Region of Madeira (Vieira 1952). The Medfly attacks more than 40 species of fruit (Vieira 1952, Pereira et al. 1996). It was reported as a pest primarily below 400 m but occurred up to 700 m on the south coast. Madeira (32 deg. N, 17 deg. W) is located 980 km west-southeast of mainland Portugal. Its two principal islands (Porto Santo (50 km 2 ) and Madeira (740 km 2 )) are populated by 255,000 people. Fruit and vegetable production is widespread on Madeira island but not on Porto Santo island because of poor soil and limited rainfall. The climate of Madeira is variable, depending upon altitude and location (northern/southern). On the whole, the climate is moderated by the effects of the surrounding sea. The sterile insect technique (SIT) is a genetic method of insect control. Large numbers (frequently more than 50 million/week) of the target insect are reared in specially designed factories (Pereira et al., in press). These insects are sterilised with gamma radiation and released by aircraft into the target area. Mating between the factory reared sterile males and fertile wild females produces no progeny. Thus, if sufficient sterile males are introduced into the target area on a continuous basis there is a very high probability that fertile wild females will mate with sterile males (Hendrichs et al. 1995). Under these conditions, the birth rate of the target species is greatly reduced and will rapidly reach zero if no fertile insects are brought into the target area. Little work has been done with all male releases because it is only very recently that all male strains have been mass produced. It has been postulated that releasing only sterile male Medflies could result in better distribution and perhaps increased longevity of the released individuals. To evaluate this hypothesis, tests of longevity and dispersion of sterile males were conducted. Ground

The fruit fly, Bactrocera dorsalis (Hendel) is a major pest of mango in India. So, investigations were carried out to standardize an Integrated Pest Management (IPM) for fruit fly-free and residue-free mango fruits. The study required orchard and laboratory studies, which were conducted on the commercial variety Banganapalli, at the Indian Institute of Horticultural Research, Hessaraghatta Lake P.O., Bangalore, India, during 2004 and 2005. Results showed that a pre harvest IPM combination of male annihilation technique (MAT) (using methyl eugenol as a lure) + sanitation brought down B. dorsalis infestation to 5.00% from an infestation ranging from 17 to 66% in control in both years. An additional cover spray of Decamethrin 2.8EC 0.5ml/l (which is half the recommended dose) + Azadirachtin (0.03 %) 2ml/l (neem based botanical) gave 100% control in both the years. Post harvest treatments with hot water at 48 degree C for 60 and 75 min resulted in 100% control at both the time regimes in 2004 and 2005. The untreated fruits, which were also exposed to gravid females (but not treated in hot water) showed 30% and 5.5% infestations, respectively, in 2004 and 2005. (author)

In this case-control study, we examined the relationship between the consumption of fruit and vegetables and risk of hip fractures in 646 pairs of incident cases and controls in elderly Chinese. We found that greater consumption of both fruit and vegetables in men and vegetables in women was associated with a lower risk of osteoporotic hip fractures in elderly Chinese. The association between fruit and vegetable consumption and the risk of osteoporotic fractures remains controversial due to limited published evidence. The purpose of this study was to determine whether consuming fruits and vegetables has a protective effect against hip fractures. Between January 2008 and December 2012, 646 (162 males, 484 females) incident cases (70.9 ± 6.8 years) of hip fractures were enrolled from five hospitals, with 646 sex- and age-matched (±3 years) controls (70.7 ± 6.8 years) from hospitals or the community. Face-to-face interviews were conducted to assess habitual dietary intakes using a 79-item food frequency questionnaire and various covariates by structured questionnaires. Multivariate conditional logistic regression analyses showed dose-dependent inverse correlations between the intake of total fruit (p-trend = 0.014), total vegetables (p-trend fruits and vegetables combined (p-trend fruits, vegetables and the combination of fruits and vegetables were 0.53 (0.32-0.87), 0.37 (0.23-0.60) and 0.25 (0.15-0.41), respectively. Stratified analyses showed that the benefits remained significant in males (p = 0.001) but not in females (p = 0.210) (p-interaction 0.045). Among the subcategories of fruits and vegetables, similar associations were observed for all subgroups except light-coloured fruits. Our findings suggest that greater consumption of both fruits and vegetables in men and vegetables in women may decrease the risk of osteoporotic hip fractures in elderly Chinese.

The scope of the study was to evaluate the prevalence of daily consumption of fruit, vegetables and greens by the elderly and its association with sociodemographic, lifestyle, morbidity and hospitalization variables. The study was part of the multiple-stage sampling cross-sectional research entitled the Goiânia Elderly Project (Projeto Idosos Goiânia). 416 elderly people were interviewed in their homes. Multivariate analysis was conducted using Poisson regression to analyze statistical associations. P values of fruit, vegetables and greens was 16.6%: fruit accounted for 44%, vegetables 39.7% and greens 32.5%. Factors statistically associated with daily consumption of fruits and vegetables were female sex, age between 70 and 79, higher education level, social class A/B and C, alcohol consumption, use of sweeteners, regular physical activity during leisure time, abdominal obesity and hospitalization. Public policies to promote health should develop strategies that encourage adequate intake of fruit, vegetables and greens among the elderly, since regular consumption of same can improve quality of life and prevent/control diseases.

Peach fruit moth, Carposina sasakii Matsumura, is a serious pest of many pome and stone fruits and presents a quarantine problem in some export markets. It is widely distributed in pome fruit production areas in China, Japan, Korea, North Korea and the Far Eastern Federal District of Russia. In this investigation, gamma radiation dose–response tests were conducted with late eggs (5-d-old) and various larval stages, followed by large-scale confirmatory tests on the most tolerant stage in fruit, the fifth instar. The dose-response tests, with the target radiation dose of 20 (late eggs), 40, 60, 80, 100, 120, 140, and 160 Gy (late fifth instars in vitro) respectively applied to all stages, showed that the tolerance to radiation increased with increasing age and developmental stage. The fifth instar (most advanced instar in fruits) was determined to be the most tolerant stage requiring an estimated minimum absorbed dose of 208.6 Gy (95% CI: 195.0, 226.5 Gy) to prevent adult emergence at 99.9968% efficacy (95% confidence level). In the confirmatory tests, irradiation was applied to 30,850 late fifth instars in apple fruits with a target dose of 200 Gy (171.6–227.8 Gy measured), but only 4 deformed adults emerged that died 2 d afterwards without laying eggs. A dose of 228 Gy may be recommended as a phytosanitary irradiation treatment under ambient atmosphere for the control of peach fruit moth on all commodities with an efficacy of 99.9902% at 95% confidence level. - Highlights: • Dose–response tests were conducted on eggs and all larval stages. • Fifth instar is the most tolerant stage that could be shipped in fruits. • None normal-looking adult emerged from 30,850 fifth instars in confirmatory tests. • A minimum of 228 Gy is suggested for phytosanitary irradiation of peach fruit moth

It has been recommended that beverages other than 100% fruit juice, such as water, be served at meals and snacks for preschool-aged children to reduce excessive energy intake. Using a 2 × 2 × 2 design (between-subjects factor of order and within-subjects factors of beverage type and size), 26 children (3.9 ± 0.6 years of age, 50% female, 73% white, and 88.5% non-Hispanic or Latino) completed four, 20-min snack sessions consisting of 200 g of applesauce, 60 g of graham crackers, and either 6 oz. (approximately 180 g) or 12 oz. (approximately 360 g) of 100% berry fruit juice or water, to examine the influence of 100% fruit juice and the portion size of the provided fruit juice, on beverage, food, and overall snack intake. Mixed-factor analyses of covariance revealed a significant (p snack energy intake, with more overall energy consumed when juice was provided (175.4 ± 50.0 kcal vs. 104.8 ± 62.8 kcal, p snack increased beverage and/or food intake, and serving 100% juice led to greater overall snack energy intake. Future research should examine the role of 100% fruit juice, and beverage portion size, in contributing to excessive daily energy intake in preschool-aged children. Copyright © 2015 Elsevier Ltd.

Wastewater analysis, or wastewater-based epidemiology, has become a common tool to monitor trends of illicit drug consumption around the world. In this study, we examined trends in cocaine, 3,4-methylenedioxymethamphetamine (MDMA) and methamphetamine consumption by measuring their residues in wastewater from two wastewater treatment plants in Australia (specifically, an urban and a rural catchment, both in South East Queensland) between 2009 and 2015. With direct injection of the samples, target analytes were identified and quantified using liquid chromatography-mass spectrometry. Cocaine and MDMA residues and metabolites were mainly quantifiable in the urban catchment while methamphetamine residues were consistently detected in both urban and rural catchments. There was no consistent trend in the population normalised mass loads observed for cocaine and MDMA at the urban site between 2009 and 2015. In contrast, there was a five-fold increase in methamphetamine consumption over this period in this catchment. For methamphetamine consumption, the rural area showed a very similar trend as the urban catchment starting at a lower baseline. The observed increase in per capita loads of methamphetamine via wastewater analysis over the past six years in South East Queensland provides objective evidence for increased methamphetamine consumption in the Australian population while the use of other illicit stimulants remained relatively stable.

Full Text Available Organic agriculture in Uganda is developing at a fast pace and despite this trend Uganda is still unable to produce enough fresh and dry organic fruits mainly pineapple to meet the exporters demand. This current research investigated the strategies of farmers at production level by assessing the pros and cons of fruit growing, organic agriculture and fruit drying in order to understand the underlying causal factor for the low production of organic dry fruits in a major fruit producing district of Uganda.The study was carried out in two separate and distinctive areas; one which only produces and export fresh organic pineapple and the other which exports dried fruits (mainly pineapple and papaya. About 10% of the farmers in the two study areas were surveyed using questionnaires which were further followed by semi-structured interviews and participatory rural appraisals activities with various types of farmers in order to understand the different decisions and strategies of farmers.82% and 74% of farmers in the two study areas grew fruits as it gave better economic returns and for 77% and 90% respectively in the two study areas, the reasons for growing fruit was the ease of selling compared to other crops. All the farmers were relying on coffee husk for growing organic pineapples. However, 50% of the farmers want to grow pineapples (either organic or conventional but couldn't afford to buy coffee husk. Fruit drying was mainly a strategy to utilize cheap fruits during harvesting seasons for value addition. 71% and 42% of farmers in the two study areas wanted to dry fruits but it was beyond their economic capacity to buy the driers.Decision of the farmers whether to grow fruits or cereals, organic or conventional agriculture and selling the fruits as fresh or dry were dependent mainly on the economic, knowledge and resource availability of each type of practices. It is concluded that the main barrier for an increase in the production of organic dried

Sterilization of the melon fly, Dacus cucurbitae Coquillett (Diptera: Tephritidae), with gamma-radiation: Effect of dose on oviposition behavior of irradiated females

International Nuclear Information System (INIS)

Teruya, T.

1990-01-01

In a laboratory condition, the visiting and the puncturing frequencies of gamma-irradiated Dacus cucurbitae females on cucumber Cucumis sativus fruits were examined. In the non-irradiated females, the frequencies reached equilibrium ca. 1 week after adult emergence. The frequencies of the irradrated females decreased with irradiation dosage, but gradually resumed frequency with age. A similar trend was found in the relationship between the irradiation dose and the rates of the puncturing frequency to the visiting frequency. As the irradiation dose increased, the rate of under-developed ovaries increased. The ratio of cumulative puncturing frequency in the 70 Gy irradiated (completely sterile) females to that of the non-irradiated females was estimated as 1/200 when daily survival rate in the field was assumed to be 0.85. The completely sterile adult females (40 days old) made punctures on all sizes of cucumber cultivated in a greenhouse. However, these punctures do not significantly damage the fruit. The sting of the sterile melon fly would not be a serious problem in eradication programs based on the Sterile Insect Technique

Lifestyle behaviours significantly contribute to high levels of chronic disease in older adults. The aims of the study were to compare the prevalence and the prevalence trends of health behaviours (physical activity, fruit and vegetable consumption, fast food consumption, TV viewing, smoking and alcohol consumption), BMI and a summary health behaviour indicator score in older (65+ years) versus younger adults (18–65 years). The self-report outcomes were assessed through the Queensland Social Survey annually between 2007–2014 (n = 12,552). Regression analyses were conducted to compare the proportion of older versus younger adults engaging in health behaviours and of healthy weight in all years combined and examine trends in the proportion of younger and older adults engaging in health behaviours and of healthy weight over time. Older adults were more likely to meet recommended intakes of fruit and vegetable (OR = 1.43, 95%CI = 1.23–1.67), not consume fast food (OR = 2.54, 95%CI = 2.25–2.86) and be non-smokers (OR = 3.02, 95%CI = 2.53–3.60) in comparison to younger adults. Conversely, older adults were less likely to meet the physical activity recommendations (OR = 0.86, 95%CI = 0.78–0.95) and watch less than 14 hours of TV per week (OR = 0.65, 95%CI = 0.58–0.74). Overall, older adults were more likely to report engaging in 3, or at least 4 out of 5 healthy behaviours. The proportion of both older and younger adults meeting the physical activity recommendations (OR = 0.97, 95%CI = 0.95–0.98 and OR = 0.94, 95%CI = 0.91–0.97 respectively), watching less than 14 hours of TV per week (OR = 0.96, 95%CI = 0.94–0.99 and OR = 0.94, 95%CI = 0.90–0.99 respectively) and who were a healthy weight (OR = 0.95, 95%CI = 0.92–0.99 and OR = 0.96, 95%CI = 0.94–0.98 respectively) decreased over time. The proportion of older adults meeting the fruit and vegetable recommendations (OR = 0.90, 95%CI = 0.84–0.96) and not consuming fast food (OR = 0.94, 95%CI = 0

Fruit tree crops are agricultural commodities of high economic importance, while fruits also represent one of the most vital components of the human diet. Therefore, a great effort has been made to understand the molecular mechanisms covering fundamental biological processes in fruit tree physiology and fruit biology. Thanks to the development of cutting-edge "omics" technologies such as proteomic analysis, scientists now have powerful tools to support traditional fruit tree research. Such proteomic analyses are establishing high-density 2DE reference maps and peptide mass fingerprint databases that can lead fruit science into a new postgenomic research era. Here, an overview of the application of proteomics in key aspects of fruit tree physiology as well as in fruit biology, including defense responses to abiotic and biotic stress factors, is presented. A panoramic view of ripening-related proteins is also discussed, as an example of proteomic application in fruit science.

2003-01-01

Four economically important fruit flies have been accidentally introduced into Hawaii: melon fly, Mediterranean fruit fly, oriental fruit fly, and the so-called Malaysian (solanaceous) fruit fly. Over 400 different host fruits are attacked. These fruit flies inhibit development of a diversified tropical fruit and vegetable industry, require that commercial fruits undergo quarantine treatment prior to export, and in Hawaii provide a breeding reservoir for their introduction into the continental United States. These exotic pests a serious threat of establishment into new areas with movement of people and commodities throughout the U.S. and the world. For example, if the Mediterranean fruit fly became established in California, projected losses would exceed $1 billion per year due to trade embargoes, loss of jobs, increased pesticide use, and direct crop loss. Present fruit fly control measures in Hawaii relay heavily on the application of organophosphate and carbamate insecticides to crops. Overuse of these insecticides has been implicated with secondary pest outbreaks, negative effects on beneficial insects, environmental contamination and adverse effects on human health. In 1999 a 5 year Area-wide Pest Management (AWPM) program was funded (for FY2000) for management of fruit flies in Hawaii. The goal of the Fruit Fly AWPM program is to develop and integrate biologically based pest management approaches that will result in area-wide suppression and control of fruit flies throughout selected agricultural areas of Hawaii. The IPM program will integrate two or more technologies into a comprehensive package that is economically viable, environmentally acceptable and sustainable. The program will result in a reduction in the use of organophosphate insecticides, and further growth and development of diversified agriculture in Hawaii. The technologies include: 1) field sanitation, 2) protein bait sprays and/or traps, 3) male annihilation with male lures and attractants, 4

Transcriptomic Analysis Reveals Candidate Genes for Female Sterility in Pomegranate Flowers

Full Text Available Pomegranate has two types of flowers on the same plant: functional male flowers (FMF and bisexual flowers (BF. BF are female-fertile flowers that can set fruits. FMF are female-sterile flowers that fail to set fruit and that eventually drop. The putative cause of pomegranate FMF female sterility is abnormal ovule development. However, the key stage at which the FMF pomegranate ovules become abnormal and the mechanism of regulation of pomegranate female sterility remain unknown. Here, we studied ovule development in FMF and BF, using scanning electron microscopy to explore the key stage at which ovule development was terminated and then analyzed genes differentially expressed (differentially expressed genes – DEGs between FMF and BF to investigate the mechanism responsible for pomegranate female sterility. Ovule development in FMF ceased following the formation of the inner integument primordium. The key stage for the termination of FMF ovule development was when the bud vertical diameter was 5.0–13.0 mm. Candidate genes influencing ovule development may be crucial factors in pomegranate female sterility. INNER OUTER (INO/YABBY4 (Gglean016270 and AINTEGUMENTA (ANT homolog genes (Gglean003340 and Gglean011480, which regulate the development of the integument, showed down-regulation in FMF at the key stage of ovule development cessation (ATNSII.

Commensal bacteria influence many aspects of an organism's behaviour. However, studies on the influence of commensal bacteria in insect mate-selection are scarce. Here, we present empirical evidence that commensal bacteria mediate mate-selection in the Oriental fruit fly, Bactrocera dorsalis. Male flies were attracted to female flies, but this attraction was abolished when female flies were fed with antibiotics, suggesting the role of the fly's microbiota in mediating mate-selection. We show that male flies were attracted to and ejaculated more sperm into females harbouring the microbiota. Using culturing and 16S rDNA sequencing, we isolated and identified different commensal bacteria, with Klebsiella oxytoca being the most abundant bacterial species. This preliminary study will enhance our understanding of the influence of commensal bacteria on mate-selection behaviour of B. dorsalis and may find use in devising control operations against this devastating pest.

Understanding the geomorphology of macrochannel systems for flood risk management in Queensland, Australia

Science.gov (United States)

Thompson, Chris; Croke, Jacky

2016-04-01

The year 2010-2011 was the wettest on record for the state of Queensland, Australia producing catastrophic floods. A tropical low pressure system in 2013 delivered further extreme flood events across South East Queensland (SEQ) which prompted state and local governments to conduct studies into flood magnitude and frequency in the region and catchment factors contributing to flood hazards. The floods in the region are strongly influenced by El Nino-Southern Oscillation (ENSO) phenomenon, but also modulated by the Interdecadal Pacific Oscillation (IPO) which leads to flood and drought dominated regimes and high hydrological variability. One geomorphic feature in particular exerted a significant control on the transmission speed, the magnitude of flood inundation and resultant landscape resilience. This feature was referred to as a 'macrochannel', a term used to describe a 'large-channel' which has bankfull recurrence intervals generally greater than 10 years. The macrochannels display non-linear downstream hydraulic geometry which leads to zones of flood expansion (when hydraulic geometry decreases) and zones of flood contraction (when hydraulic geometry increases). The pattern of contraction and expansion zones determines flood hazard zones. The floods caused significant wet flow bank mass failures that mobilised over 1,000,000 m3 of sediment in one subcatchment. Results suggest that the wetflow bank mass failures are a stage in a cyclical evolution process which maintains the macrochannel morphology, hence channel resilience to floods. Chronological investigations further show the macrochannels are laterally stable and identify periods of heightened flood activity over the past millennium and upper limits on flood magnitude. This paper elaborates on the results of the geomorphic investigations on Lockyer Creek in SEQ and how the results have alerted managers and policy makers to the different flood responses of these systems and how flood risk management plans can

2016-03-15

The extinct hemipteran family Dysmorphoptilidae was a major component of the Triassic insect fauna of Queensland preserved at the Denmark Hill, Dinmore, Mount Crosby and Gayndah fossil insect sites. A total of 13 species have now been identified, of which eight species in five genera were examined in the first part of this revision. This second part revises the remaining five species in three genera. Eoscartoides Evans, 1956 (= Mesonirvana Evans, 1956, syn. nov.), comprising Eoscartoides bryani Evans, 1956 (= Mesonirvana abrupta Evans, 1956, syn. nov.) (Mount Crosby), Eoscartoides orthocladus (Tillyard, 1922) comb. nov. (Denmark Hill), and Eoscartoides dmitryi sp. nov. (Dinmore), is distinguished by a strongly developed arc-like strigil in the basal costal space, a very short stem of RA, and a deeply forked M1+2. The monotypic Eoscarterella Evans, 1956, with type species Eoscarterella media Evans, 1956 (Mount Crosby), has a strongly lobate tegmen with peculiar surface sculpture and M1+2 simple. Eoscartoides and Eoscarterella differ from most dysmorphoptilids in having more or less lobate tegmina with even margins (without the antero-apical emargination so typical of the family), as well as the early entry of RA1 into the costal margin and the associated extensive and antero-apically positioned RA2. These characters are also shared with two other dysmorphoptilids, the Australian Permian Belmontocarta Evans and an unnamed Triassic species from Kyrgyzstan, and the four thus form a distinct subgroup within the family. On the other hand, the monotypic Trifidella Evans, 1956 (= Alotrifidus Evans, 1956, syn. nov.), with type species Trifidella perfecta Evans, 1956 (= Alotrifidus interruptus Evans, 1956, syn. nov.) (Mount Crosby), is a more typical dysmorphoptilid with a distinct emargination, RA entering the margin much more apically, and RA2 of limited extent. Trifidella is presumably the sister of the Queensland Triassic Dysmorphoptiloides Evans, sharing the basal

The macrolide azithromycin is recommended for treatment of Mycoplasma genitalium infection; however, M. genitalium strains possessing macrolide resistance-mediating mutations (MRMMs) are increasingly being reported. Here, we used the SpeeDx ResistancePlus MG kit, which provides simultaneous detection of M. genitalium and MRMMs, to assess MRMM carriage among M. genitalium infections in Queensland, Australia. Performance characteristics of the ResistancePlus MG kit for M. genitalium detection were compared to in-house PCR. Available M. genitalium PCR-positive (n=67) and negative (n=281) samples from the years 2011 to 2017 were tested using the SpeeDx ResistancePlus MG kit. In total, 63.6 % M. genitalium-positive samples were indicated to harbour MRMMs. The ResistancePlus MG method provided sensitivity and specificity of 97 and 99.6 % respectively compared to in-house PCR for M. genitalium detection. Such high levels of macrolide-resistant M. genitalium raise further concerns over future use of azithromycin for treatment of M. genitalium infection.

Numerous popular media sources have developed lists of "Super Foods" and, more recently, "Super Fruits". Such distinctions often are based on the antioxidant capacity and content of naturally occurring compounds such as polyphenols within those whole fruits or juices of the fruit which may be linked to potential health benefits. Cocoa powder and chocolate are made from an extract of the seeds of the fruit of the Theobroma cacao tree. In this study, we compared cocoa powder and cocoa products to powders and juices derived from fruits commonly considered "Super Fruits". Various fruit powders and retail fruit products were obtained and analyzed for antioxidant capacity (ORAC (μM TE/g)), total polyphenol content (TP (mg/g)), and total flavanol content (TF (mg/g)). Among the various powders that were tested, cocoa powder was the most concentrated source of ORAC and TF. Similarly, dark chocolate was a significantly more concentrated source of ORAC and TF than the fruit juices. Cocoa powder and dark chocolate had equivalent or significantly greater ORAC, TP, and TF values compared to the other fruit powders and juices tested, respectively. Cacao seeds thus provide nutritive value beyond that derived from their macronutrient composition and appear to meet the popular media's definition of a "Super Fruit".

2001-10-01

Males and virgin females of the citrus fruit borer Ecdytolopha aurantiana Lima, displayed two flight peaks during a 24-hr period, one at dawn and the other at dusk in an orange grove near Gavião Peixoto, São Paulo, Brazil. During the day, when temperatures were highest and relative humidity lowest, most individuals rested on leaves in the lower and middle crown. Moths rapidly moved higher in the crown after sunset, and many were observed flying above the tree canopy. This behavior was mainly associated with mating. Males and virgin females marked with fluorescent powder of different colors were observed in the dark with the aid of a black light. Mating was observed only in the upper crown of citrus trees from 6:00 to 9:00 PM, with a peak (64%) between 7:00 and 8:00 PM. Males of E. aurantiana were captured in traps baited either with virgin females or female extracts, suggesting the use of a long-range sex pheromone. At close distance (1-2 cm), males and females displayed a short-range communication behavior, with males exposing hairpencils and vibrating their wings. Females were frequently stimulated to contact the body of a male before copulation. The mean duration of copulation was 1 hr 40 min.

1986-01-01

The current status of research on the application of ionizing radiation for improving the storage of temperate fruits, i.e., apple, pear, peach, nectarine, apricot, cherry, plum, strawberry, bilberry, cranberry, raspberry, and black currant, is reviewed. Changes in fruit metabolism, chemical composition, texture, and organoleptic quality attributes are discussed with reference to the irradiation dose. The feasibility of using radiation either alone or in conjunction with heat treatment, refrigeration, and controlled atmospheres (CA) for the control of storage decay caused by fungal pathogens is considered. Areas of further research are suggested before irradiation could be considered for practical application in some of these temperate fruits. The recent trends in the possible use of irradiation for disinfestation of certain pome and stone fruits and the prospects for the commercial utilization of irradiation for improving the market life of strawberries are discussed. 156 references

In this study, an F1 population was created by the cross 87-1*9-22. The female parent 87-1 was a black purple cultivar and the male parent was an excellent breeding line with green pericarp. the skin color separation of population and distribution, and determined the content of each individual fruit peel pigment. On the basis of the genetic map of Vitis vinifera L. We carried out the grape skin pigment content quantitative trait locus (QTL) analyses. The results show that the fruit color performance for continuous variation and the inheritance of fruit skin anthocyanidin content was a quantitative inheritance. The color of offspring ranges from green and black-blue and existing distribution. Using SSR and SRAP molecular markers to construct 188 female parent maps,175 male parent maps and 251 consensus maps, and the total map distance is 1047.5 cM,1100.2 cM and 1264.2 cM respectively. The result of QTL showed that there were more QTLs exist in the linkage group of 1, 2, 3, 4, 9, 13, 14, 16 and 19 and in the linkage group of 3, 4, 13 and 14, we detected QTLs in the similar position with the result of the study in the year of 2011 and 2012, and based on this we will conduct the fine QTL location in the future, this result will lay a good foundation for the grape in the department of molecular assistant breeding in the future.

The 2010-2011 Queensland floods resulted in the most deaths from a single flood event in Australia since 1916. This article analyses the information on these deaths for comparison with those from previous floods in modern Australia in an attempt to identify factors that have contributed to those deaths. Haddon's Matrix, originally designed for prevention of road trauma, offers a framework for understanding the interplay between contributing factors and helps facilitate a clearer understanding of the varied strategies required to ensure people's safety for particular flood types. Public reports and flood relevant literature were searched using key words 'flood', 'fatality', 'mortality', 'death', 'injury' and 'victim' through Google Scholar, PubMed, ProQuest and EBSCO. Data relating to reported deaths during the 2010-2011 Queensland floods, and relevant data of previous Australian flood fatality (1997-2009) were collected from these available sources. These sources were also used to identify contributing factors. There were 33 deaths directly attributed to the event, of which 54.5% were swept away in a flash flood on 10 January 2011. A further 15.1% of fatalities were caused by inappropriate behaviours. This is different to floods in modern Australia where over 90% of deaths are related to the choices made by individuals. There is no single reason why people drown in floods, but rather a complex interplay of factors. The present study and its integration of research findings and conceptual frameworks might assist governments and communities to develop policies and strategies to prevent flood injury and fatalities. © 2013 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Prevention of metabolic diseases: fruits (including fruit sugars) vs. vegetables.

Science.gov (United States)

Kuzma, Jessica N; Schmidt, Kelsey A; Kratz, Mario

2017-07-01

To discuss recent evidence from observational and intervention studies on the relationship between fruit and vegetable (F&V) consumption and metabolic disease. Observational studies have consistently demonstrated a modest inverse association between the intake of fruit and leafy green vegetables, but not total vegetables, and biomarkers of metabolic disease as well as incident type 2 diabetes mellitus. This is in contrast to limited evidence from recently published randomized controlled dietary intervention trials, which - in sum - suggests little to no impact of increased F&V consumption on biomarkers of metabolic disease. Evidence from observational studies that fruit and leafy green vegetable intake is associated with lower type 2 diabetes risk and better metabolic health could not be confirmed by dietary intervention trials. It is unclear whether this discrepancy is because of limitations inherent in observational studies (e.g., subjective dietary assessment methods, residual confounding) or due to limitations in the few available intervention studies (e.g., short duration of follow-up, interventions combining whole fruit and fruit juice, or lack of compliance). Future studies that attempt to address these limitations are needed to provide more conclusive insight into the impact of F&V consumption on metabolic health.

Fruit exports account for 9% of Argentina's total agricultural exports and generate annually close to $450 million. This could be increased but for fruit flies that cause damage equivalent to 15% to 20% of present production value of fruit and also deny export access to countries imposing quarantine barriers. The Department of Technical Co-operation is sponsoring a programme, with technical support from the Joint FAO/IAEA Division, to eradicate the Mediterranean fruit fly using the Sterile Insect Technique (SIT).

Peach fruit moth, Carposina sasakii Matsumura, is a serious pest of many pome and stone fruits and presents a quarantine problem in some export markets. It is widely distributed in pome fruit production areas in China, Japan, Korea, North Korea and the Far Eastern Federal District of Russia. In this investigation, gamma radiation dose-response tests were conducted with late eggs (5-d-old) and various larval stages, followed by large-scale confirmatory tests on the most tolerant stage in fruit, the fifth instar. The dose-response tests, with the target radiation dose of 20 (late eggs), 40, 60, 80, 100, 120, 140, and 160 Gy (late fifth instars in vitro) respectively applied to all stages, showed that the tolerance to radiation increased with increasing age and developmental stage. The fifth instar (most advanced instar in fruits) was determined to be the most tolerant stage requiring an estimated minimum absorbed dose of 208.6 Gy (95% CI: 195.0, 226.5 Gy) to prevent adult emergence at 99.9968% efficacy (95% confidence level). In the confirmatory tests, irradiation was applied to 30,850 late fifth instars in apple fruits with a target dose of 200 Gy (171.6-227.8 Gy measured), but only 4 deformed adults emerged that died 2 d afterwards without laying eggs. A dose of 228 Gy may be recommended as a phytosanitary irradiation treatment under ambient atmosphere for the control of peach fruit moth on all commodities with an efficacy of 99.9902% at 95% confidence level.

To determine whether food label information and advertisements for foods containing no fruit cause children to have a false impression of the foods' fruit content. In the food label condition, a trained researcher showed each child sixteen different food label photographs depicting front-of-food label packages that varied with regard to fruit content (i.e. real fruit v. sham fruit) and label elements. In the food advertisement condition, children viewed sixteen, 30 s television food advertisements with similar fruit content and label elements as in the food label condition. After viewing each food label and advertisement, children responded to the question 'Did they use fruit to make this?' with responses of yes, no or don't know. Schools, day-care centres, after-school programmes and other community groups. Children aged 4-7 years. In the food label condition, χ 2 analysis of within fruit content variation differences indicated children (n 58; mean age 4·2 years) were significantly more accurate in identifying real fruit foods as the label's informational load increased and were least accurate when neither a fruit name nor an image was on the label. Children (n 49; mean age 5·4 years) in the food advertisement condition were more likely to identify real fruit foods when advertisements had fruit images compared with when no image was included, while fruit images in advertisements for sham fruit foods significantly reduced accuracy of responses. Findings suggest that labels and advertisements for sham fruit foods mislead children with regard to the food's real fruit content.

The objective of the present research was to determine if gamma radiations could be used as a quarentenary process against the orange fruit borer, Ecdytolopha aurantiana (Lima, 1927), infesting oranges of the variety 'Pera', beyond observations on some fruit quality parameters. To observe the gamma radiations effects on the insects, doses ranging from the control to 800 Gy were used, and to observe possible effects on fruits quality, the utilized doses ranges from the control to 500 Gy. To observe the gamma radiations effects on the insects, doses ranging from the control to 800 Gy were used, and to observe possible effects on fruits quality, the utilized doses ranged from the control to 500 Gy. It was observed that over 200 Gy avoid emergency of viable adults of the orange fruit borer. Only one single female, and even these with wing malformations, emerged at the dose of 300 Gy. Dose up to 500 Gy did not interfere on fruits weight loss nor on the period of conservation of the oranges. Acidity, Brix value and skin resistance against perforation also did not showed any changes due to radiations. The irradiation of green fruit induced into a smaller loss of weight than when the fruits were irradiated in the mature stage. (author)

Respiratory diseases are a leading cause of morbidity and mortality in Indigenous Australians. However, there are limited approaches to specialist respiratory care in rural and remote communities that are culturally appropriate. A specialist Indigenous Respiratory Outreach Care (IROC) program, developed to address this gap, is described. The aim of the present study was to implement, pilot and evaluate multidisciplinary specialist respiratory outreach medical teams in rural and remote Indigenous communities in Queensland, Australia. Sites were identified based on a perception of unmet need, burden of respiratory disease and/or capacity to use the clinical service and capacity building for support offered. IROC commenced in March 2011 and, to date, has been implemented in 13 communities servicing a population of approximately 43000 Indigenous people. Clinical service delivery has been possible through community engagement and capacity building initiatives directed by community protocols. IROC is a culturally sensitive and sustainable model for adult and paediatric specialist outreach respiratory services that may be transferrable to Indigenous communities across Queensland and Australia.

Following the introduction of vaccination against Haemophilus influenzae type b (Hib), cases of invasive encapsulated Hib disease have decreased markedly. This study aimed to examine subsequent epidemiological trends in invasive H. influenzae disease in Queensland, Australia and in particular, assess the clinical impact and public health implications of invasive non-typable H. influenzae (NTHi) strains. A multicentre retrospective study was conducted from July 2000 to June 2013. Databases of major laboratories in Queensland including Queensland Forensic and Scientific Services (jurisdictional referral laboratory for isolate typing) were examined to identify cases. Demographic, infection site, Indigenous status, serotype, and mortality data were collected. In total, 737 invasive isolates were identified, of which 586 (79·5%) were serotyped. Hib, NTHi and encapsulated non-b strains, respectively, constituted 12·1%, 69·1% and 18·8% of isolates. The predominant encapsulated non-b strains were f (45·5%) and a (27·3%) serotypes. Of isolates causing meningitis, 48·9% were NTHi, 14·9% Hib, 14·9% Hie, 10·6% Hif, 6·4% Hia and 4·3% were untyped. During the study period, there was an increase in the incidence of invasive NTHi disease (P = 0·007) with seasonal peaks in winter and spring (P 0·001) and Hib (P = 0·039) than non-Indigenous patients. In Queensland, invasive H. influenzae disease is now predominantly encountered in adults and most commonly caused by NTHi strains with demonstrated pathogenicity extending to otherwise young or immunocompetent individuals. Routine public health notification of these strains is recommended and recent available immunization options should be considered.

Model-assisted analysis of spatial and temporal variations in fruit temperature and transpiration highlighting the role of fruit development.

Fruit physiology is strongly affected by both fruit temperature and water losses through transpiration. Fruit temperature and its transpiration vary with environmental factors and fruit characteristics. In line with previous studies, measurements of physical and thermal fruit properties were found to significantly vary between fruit tissues and maturity stages. To study the impact of these variations on fruit temperature and transpiration, a modelling approach was used. A physical model was developed to predict the spatial and temporal variations of fruit temperature and transpiration according to the spatial and temporal variations of environmental factors and thermal and physical fruit properties. Model predictions compared well to temperature measurements on mango fruits, making it possible to accurately simulate the daily temperature variations of the sunny and shaded sides of fruits. Model simulations indicated that fruit development induced an increase in both the temperature gradient within the fruit and fruit water losses, mainly due to fruit expansion. However, the evolution of fruit characteristics has only a very slight impact on the average temperature and the transpiration per surface unit. The importance of temperature and transpiration gradients highlighted in this study made it necessary to take spatial and temporal variations of environmental factors and fruit characteristics into account to model fruit physiology.

Model predictions compared well to temperature measurements on mango fruits, making it possible to accurately simulate the daily temperature variations of the sunny and shaded sides of fruits. Model simulations indicated that fruit development induced an increase in both the temperature gradient within the fruit and fruit water losses, mainly due to fruit expansion. However, the evolution of fruit characteristics has only a very slight impact on the average temperature and the transpiration per surface unit. The importance of temperature and transpiration gradients highlighted in this study made it necessary to take spatial and temporal variations of environmental factors and fruit characteristics into account to model fruit physiology.

Full Text Available Abstract Background Apple fruit develop over a period of 150 days from anthesis to fully ripe. An array representing approximately 13000 genes (15726 oligonucleotides of 45–55 bases designed from apple ESTs has been used to study gene expression over eight time points during fruit development. This analysis of gene expression lays the groundwork for a molecular understanding of fruit growth and development in apple. Results Using ANOVA analysis of the microarray data, 1955 genes showed significant changes in expression over this time course. Expression of genes is coordinated with four major patterns of expression observed: high in floral buds; high during cell division; high when starch levels and cell expansion rates peak; and high during ripening. Functional analysis associated cell cycle genes with early fruit development and three core cell cycle genes are significantly up-regulated in the early stages of fruit development. Starch metabolic genes were associated with changes in starch levels during fruit development. Comparison with microarrays of ethylene-treated apple fruit identified a group of ethylene induced genes also induced in normal fruit ripening. Comparison with fruit development microarrays in tomato has been used to identify 16 genes for which expression patterns are similar in apple and tomato and these genes may play fundamental roles in fruit development. The early phase of cell division and tissue specification that occurs in the first 35 days after pollination has been associated with up-regulation of a cluster of genes that includes core cell cycle genes. Conclusion Gene expression in apple fruit is coordinated with specific developmental stages. The array results are reproducible and comparisons with experiments in other species has been used to identify genes that may play a fundamental role in fruit development.

Radial fruit cracking (RFC) can contribute to serious economic losses in tomato production under rain shelter in cool uplands. In order to investigate the effects of translocation and distribution of photosynthate to the fruits during the occurrence of RFC, tomato plants were grown under treatments with fruit thinning and CO2 enrichment, which regulate the strength of sink and source, and treatments with covering of the fruit truss, which decreases solar radiation incident on the fruit surface. The occurrence of RFC was increased by fruit thinning and CO2 enrichment, and decreased by covering of fruit truss. Time course of the percentage of RFC to total harvest showed a remarkable rise toward the end of August and toward the end of October in 2004, when harvested fruit weight was increasing. These finding suggest that RFC is attributed to excessive enlargement of the fruit by promotion of translocation and distribution of photosynthate from leaves (source) to fruits (sink) and the solar radiation incident on the fruits. In addition, the relation between RFC and the generation of a cork layer is considered

The 2015 to 2020 Dietary Guidelines for Americans (DGAs) recognize the role of 100% fruit juice in health and in helping people meet daily fruit recommendations and state that 100% fruit juice is a nutrient-dense beverage that should be a primary choice, along with water and low-fat/fat-free milk. The DGAs note that children are consuming 100% fruit juice within recommendations (that is, 120 to 180 mL/d for children aged 1 to 6 y and 236 to 355 mL/d for children aged 7 to 18 y). Evidence shows that compared to nonconsumers, those who consume 100% fruit juice come closer to meeting daily fruit needs and have better diet quality. In children, 100% fruit juice is associated with increased intakes of nutrients such as vitamin C, folate, and potassium. When consumed within the DGA recommendations, 100% fruit juice is not associated with overweight/obesity or childhood dental caries and does not compromise fiber intake. Preliminary data suggest that polyphenols in some 100% fruit juices may inhibit absorption of naturally occurring sugars. Given its role in promoting health and in helping people meet fruit needs, experts participating in a roundtable discussion agreed that there is no science-based reason to restrict access to 100% fruit juice in public health nutrition policy and programs such as the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Reducing or eliminating 100% fruit juice could lead to unintended consequences such as reduced daily fruit intake and increased consumption of less nutritious beverages (for example, sugar-sweetened beverages). © 2017 Institute of Food Technologists®.

Purpose: Primary radiation therapy following breast-conserving surgery has been an accepted alternative to mastectomy in Europe and North America for many years. In Australia, however, the history of breast conservation for early invasive breast cancer is much shorter. The purpose of this study was to evaluate the results of breast conservation in a state-wide Australian radiotherapy service. Methods and Materials: Between January 1982 and December 1989, 512 patients were treated with primary radiation therapy after breast conserving surgery. This analysis is based on a review of these patients, all of whom had Stage I or II breast cancer. Results: With a median follow-up of 50 months, the 5-year actuarial rate of overall survival was 84% and disease-free survival was 80%. There have been 22 isolated local recurrences in the breast. The time to an isolated breast recurrence ranged from 12 to 83 months (median, 26 months). The 5-year actuarial rate of an isolated breast recurrence was 4%. The recurrence rate was higher for patients with involved margins (15% vs. 2%, p < 0.01). Local recurrence was also more likely in the presence of extensive ductal carcinoma insitu (DCIS), as opposed to no extensive DCIS (10% vs. 2%, p < 0.01). Conclusion: These results affirm that primary radiation therapy after breast conserving surgery in Queensland, has been given with a low rate of local recurrence, comparable to that obtained in other centers

Full Text Available The white mulberry, Morus alba L. has been used by several Asian societies for the treatment of infertility. However, there is no evidence that products of the plant can influence ovarian health. Thus, the aim of this study was to determine the effect of the Morus alba fruit extract on the ovarian function of nonpregnant and pregnant rats. The study showed that in rats Morus alba fruit extract stimulates follicular stimulating (FSH and luteinizing hormones (LH, estrogen, and progesterone productions that peaked at 8 days of treatment. The effect was dose-dependent with hormone production increasing with increase in dose of the extract. The Graafian follicles were fully matured, and the number increased with increase in dose of the extract. The uterus of pregnant rats contained several embryos that gave birth to the full-term offspring without abortion or embryonic abnormalities. In conclusion, the Morus alba fruit extract can be used to induce superovulation to cause multiple pregnancies. Thus, the Morus alba fruit extract has potential to be developed into a compound for the treatment of female infertility.

Do Small Canopy Gaps Created by Japanese Black Bears Facilitate Fruiting of Fleshy-Fruited Plants?

Full Text Available Japanese black bears often break branches when climbing trees and feeding on fruit in canopies, thereby creating small canopy gaps. However, the role of black bear-created canopy gaps has not been evaluated in the context of multiple forest dynamics. Our hypothesis was that small canopy gaps created by black bears improve light conditions, which facilitates fruiting of adult fleshy-fruited plants located beneath the gaps, and also that this chain interaction depends on interactions among the size of gaps, improved light conditions, forest layers, and life form of plants. The rPPFD, size of black bear-created canopy gaps, and fruiting/non-fruiting of fleshy-fruited plants were investigated in five forest layers beneath black-bear-created canopy gaps and closed canopies of Mongolian oak (Quercus crispula. We found that light conditions improved beneath black bear-disturbed trees with canopy gaps of large size, and the effect of improvement of light conditions was reduced with descending forest layers. Fruiting of fleshy-fruited plants, especially woody lianas and trees, was facilitated by the improvement of light conditions accompanied by an increase in the size of black-bear-created gaps. Data from this study revealed that canopy disturbance by black bears was key for improving light conditions and accelerating fruiting of fleshy-fruited trees and woody lianas in the canopy layers in particular. Therefore, our hypothesis was mostly supported. Our results provide evidence that Japanese black bears have high potential as ecosystem engineers that increase the availability of resources (light and fruit in this study to other species by causing physical state changes in biotic materials (branches of Q. crispula in this study.

Fruit photosynthesis in Satsuma mandarin.

To clarify detailed characteristics of fruit photosynthesis, possible gas exchange pathway and photosynthetic response to different environments were investigated in Satsuma mandarin (Citrus unshiu). About 300 mm(-2) stomata were present on fruit surface during young stages (∼10-30 mm diameter fruit) and each stoma increased in size until approximately 88 days after full bloom (DAFB), while the stomata collapsed steadily thereafter; more than 50% stomata deformed at 153 DAFB. The transpiration rate of the fruit appeared to match with stoma development and its intactness rather than the density. Gross photosynthetic rate of the rind increased gradually with increasing CO2 up to 500 ppm but decreased at higher concentrations, which may resemble C4 photosynthesis. In contrast, leaf photosynthesis increased constantly with CO2 increment. Although both fruit and leaf photosynthesis were accelerated by rising photosynthetic photon flux density (PPFD), fruit photosynthesis was greater under considerably lower PPFD from 13.5 to 68 μmolm(-2)s(-1). Thus, Satsuma mandarin fruit appears to incorporate CO2 through fully developed and non-collapsed stomata, and subject it to fruit photosynthesis, which may be characterized as intermediate status among C3, C4 and shade plant photosynthesis. The device of fruit photosynthesis may develop differently from its leaf to capture CO2 efficiently. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Full Text Available The influence of four host fruits, orange (Citrus sinensis L., papaya (Carica papaya L., mango (Mangifera indica L. and apple (Malus domestica Borkh on oviposition behavior of Ceratitis capitata (Wiedemann, 1824 was evaluated. Experiments were carried out on two C. capitata laboratory-reared populations: one with artificial diet for 10 years with periodic introduction of wild flies and other reared with artificial diet for 20 years without wild flies introduction. In acceptance experiments two pieces of a single fruit type were exposed to a group of 10 females; after 48 hours, these were changed by two new pieces of the same fruit type, and, in the end of the fourth day, the experiments were concluded. In preference experiments, two pieces of different fruits were offered to the females. These experiments were driven under the same conditions of the acceptance ones. Acceptance and preference experiments for both populations showed the following choice hierarchy: papaya > mango > orange > apple. The acceptance experiments showed no differences in the number of eggs/female/day laid in the first 48 hours and in the last 48 hours of the experiments. The amount of eggs in the two pieces of fruits offered to the females was similar. In spite of the two populations present similar behavior in relation to host hierarchy, the number of laid eggs was different, being larger for the population reared without wild flies introduction.

Labelling of the mediterranean fruit fly Ceratitis capitata (Wied., 1824) (Diptera: Tephritidae), with stable manganese and neutron activation, for behaviour studies

In view to label adults of the Mediterranean fruit fly for behaviour studies (etiology) experiments were carried out using larvae feeded with enriched stable manganese on concentrations of 0; 0.0001; 0.0005; 0.0010; 0.0050 and 0.0100 grams of MnCl2 per gram of diet. Also a comparison was done between larvae reared on natural fruits (Coffea arabica, Eriobotaya japonica, Syzugium jambos, Eugenia uvalha, Prunus persica and Psidium guajava) and on artificial diet. The low concentration of manganese (0.0001 grams of MnCl2 per gram of larval diet) acted only as a micronutrient. Concentrations of 0.0005 and 0.0010 grams of MnCl2 per gram of diet didn't affect larvae or adults, increasing the longevity of the females. Concentrations of 0.0050 and 0.0100 grams of MnCl2 per gram of larval diet completely inhibited the development of the insects. The flies activated by a flux of 2.67.10 sup(11) n/cm sup(2)/s during 60 second and counted by a germanium detector during 120 seconds showed that males and females remained well labeled until the 13 sup(th) day of adult life, if their larvae were feed on diet containing 0.0005 and 0.0010g of MnCl2 per gram of diet. However, after 25 days only the males emerged from larvae reared on diet containing 0.0005 g of MnCl2 per gram of diet remained labeled. The females excreted the most of manganese, probably through their laying eggs. The quantity of accumulated manganese detected on the adults after neutron activation and reared on different fruits was very similar, for any kind of fruit. (author)

RELATIONSHIP BETWEEN YIELD AND FRUIT QUALITY OF PASSION FRUIT C03 PROGENIES UNDER DIFFERENT NUTRITIONAL LEVELS

Directory of Open Access Journals (Sweden)

CARLOS LACY SANTOS

Full Text Available ABSTRACT The present study was conducted to evaluate different fertilization-management strategies in ten progenies of passion fruit from the third recurrent selection cycle and their effects on yield and fruit-quality traits. For this purpose, we adopted the strategy of correlations analysis, using the phenotypic and path correlations in different environmental conditions characterized by three levels of fertilization. The trial was set up as a randomized-block design in a split-plot arrangement with progenies representing the plots and three levels of potassium-nitrogen fertilization as the sub-plots, with three replicates. Path analysis showed that number of fruits was the variable of highest correlation with fruit diameter at fertilization I. Fruit weight and pulp weight were correlated with each other and with other traits like fruit length and fruit diameter at the three fertilization levels, except for number of fruits, which was correlated with nitrogen and potassium only at fertilization II. Path analysis also revealed that fruit diameter (3.125 showed the highest direct effect on yield at fertilization I. However, fruit weight and number of fruits showed, at fertilization II, the highest direct effects of 2.964 and 1.134 on yield, respectively, and number of fruits had a high phenotypic correlation and direct effect on yield at the three fertilization levels: 0.528 at fertilization I; 2.206 at fertilization II; and 0.928 at fertilization III. The results demonstrate the greater direct effect obtained with fertilization II, suggesting that the level adopted at fertilization II can provide satisfactory gains in yield and is thus recommended for the population in question.

Incorporating palaeoclimate data into water security planning and decision making - a case study from southeast Queensland, Australia

Decision makers in the water sector need to deal with existing hydroclimatic variability and uncertainty about future changes to climate and catchment conditions. Identifying solutions for hydroclimatic risk adaptation strategies that are both optimal and robust in the presence of variability and uncertainty presents a difficult challenge. A major reason for this challenge is the fact that the instrumental record in Australia is short ( 60-130 years) and fails to encompass enough climate variability to allow the calculation of robust statistics around the baseline risk of extreme events (e.g. multi-year droughts, decadal periods with clustering of major flood events). This climate variability is documented pre-1900 in palaeoclimate records from sources such as corals, tree-rings, freshwater and marine sediments. Despite being remote from Queensland, a high resolution and highly correlated palaeoclimate record from the Law Dome ice cores in Antarctica (Vance et al. 2015) is also now available and has identified eight mega-droughts (lasting from 5-39 years) during 1000-2009 AD. Most importantly, the palaeoclimate information confirms that the post-1900 instrumental period (i.e. the period on which all water resources infrastructure, policy, operation rules and strategies is based) does not capture the full range of variability that has occurred. Other work also clearly shows that, out to 2050 at least, impacts associated with natural variability significantly exceed even the worst-case climate change scenarios (i.e. obtained from Global Climate Models run under the highest emission scenarios). This presentation will demonstrate how the Law Dome ice cores from Antarctica have been used to produce a highly accurate, 1000 year, annual and seasonal resolution, hydroclimate reconstruction (i.e. precipitation and streamflow) for the southeast Queensland region of Australia. We will then show how the palaeoclimate data has been incorporated into the South East Queensland

1990-01-01

A genetic sexing system in the Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann), is urgently required in order to reduce the costs of mass rearing and to prevent punctures in fruit made by the ovipositors of sterilized females. Two genetic sexing strains, T(Y,5)122; T:Y(wp), white pupae, and T(Y,3,5)11; T:Y(dp + wp + ), were isolated and studied in connection with their possible use in a mass rearing programme. Both strains have males emerging from wild type brown pupae and females emerging from mutant pupae; they are stable up to generation 22. The strain T(Y,5)122 has a translocation linking the Y chromosome with the autosome carrying the wp locus. The strain T(Y,3,5)11 has a translocation linking the Y chromosome and the two chromosomes carrying the wp and the dp loci. The egg fertility of the strain T(Y,5)122 was 52% and that of T(Y,3,5)11 was 48%. Larval survival of the latter line was 79%. The technical advantages of these strains was discussed in this paper. The strain T(Y,4)116; T:Y(ap + ), apricot eye, is characterized by wild type males and apricot eye females, as well as apricot eye sterile males. A model explaining the appearance of these ap males is proposed. Isolation and preliminary fertility studies of six sex linked multiple translocations are presented. Each of these strains has three translocations involving the chromosomes Y, 3, 4 and 5. (author). 13 refs, 4 tabs

To assess risk for importation of dengue virus (DENV) into Queensland, Australia, and sources of imported viruses, we sequenced the envelope region of DENV isolates from symptomatic patients with a history of travel during 2002–2010. The number of imported dengue cases greatly increased over the surveillance period, some of which were associated with domestic outbreaks. Patients reported traveling to (in order) Asia, Papua New Guinea, Pacific Island countries, and non–Asia-Pacific countries. By using phylogenetic methods, we assigned DENV isolates from returning residents and overseas visitors with viremia to a specific genotypic group. Genotypes circulating in Asia were extremely diverse. Genotyping and molecular clock analysis supported Asian origination of a strain that caused an outbreak of DENV-4 in Pacific Island countries during 2007–2009, and subsequently, in Innisfail, Australia, in 2009. Our findings indicate that Asia is a major source of DENVs that are imported into Australia, causing a risk for epidemics. PMID:23092682

Changes in reproductive state or the environment may affect the sensitivity of the hypothalamic-pituitary-andrenal (HPA) axis. However, little is known about the dynamics of the resulting corticosteroid stress response, in particular in tropical mammals. In this study, we address the modulation of corticosterone release in response to different reproductive conditions and seasonality in 326 free-living common fruit-eating bats (Artibeus jamaicensis) on Barro Colorado Island in Panama during dry and wet seasons. We present strong evidence that stress sensitivity is primarily modulated by reproductive condition. In reproductively active females, corticosterone increases were more rapid and reached higher levels, but also decreased significantly faster than in inactive females. The corticosterone response was weaker in reproducing males than in females and delayed compared to non-reproductive males. Testes volume in reproductively active males was negatively correlated with corticosterone concentrations. Our findings suggest differentiated dynamics in the corticosterone stress response between sexes, potentially reflecting conflicting ecological demands. In females, a strong acute corticosterone response may represent high stress- and risk-sensitivity that facilitates escape and thus helps to protect reproduction. In males, suppression during reproductive activity could reflect lowered stress sensitivity to avoid chronically elevated corticosterone levels in times of frequent aggressive and therefore costly inter-male encounters.

Medicinal Fruits in Holy Quran

Full Text Available Fruits are one of the oldest forms of food known to man. There are many references to fruits in ancient literature. According to Quran, the fruits like grape, date, fig, olive and pomegranate are gifts and heavenly fruits of God.  Fresh and dry fruits are the natural staple food of man. They contain substantial quantities of essential nutrients in a rational proportion. Persons subsisting on this natural diet will always enjoy good health. Moreover, fresh and dry fruits are thus not only a good food but also a good medicine. Holy Quran is one of the reference books describing the importance of plants used for different ailments in various verses. There are several verses in Quran talking about the fruits in Paradise, including; date, olive, pomegranate, grape, banana and fig. What has been mentioned in the Quran is what scientists have achieved over the time, since the Quran is governed by logic. Although we do not know the reasons for many things in the Quran, we consider it as the foundation.

Irradiation as a quarantine treatment against the invader fruit fly (Bactrocera Invadens, Drew) in mangoes (Mangifera Indica L,)

International Nuclear Information System (INIS)

Odai, B.T.

2010-06-01

The detection of the African invader fly, Bactrocera invadens Drew, Tsuruta and White, in Ghana has led to limitations in the export of mango fruits from Ghana to other countries. The limitations ranging from increased control costs to outright rejection of exports has necessitated a study in the area of quarantine treatment. A study was conducted to ascertain the effectiveness of gamma radiation for control of Bactrocera invadens in fruit destined for export. Pupae were obtained from the incubation of mango fruits collected from various locations. Adults were reared and infestation levels were determined after fruits were exposed to 5, 10, 20 females in different cages. Late instar larvae in fruits were irradiated at 15, 25, 35, 45, 50, 60 and 75 Gy to determine an effective dose for B. invadens. The mortality of the fly was determined at the various doses to obtain a probit 9 figure of 68.06 Gy (rounded to 70 Gy). The confirmatory test for 3050 larvae endorsed the effective dose as the probit 9 dose. Non-infested mature green export grade mango fruits were irradiated with 0, 70 and 150 Gy to determine its effect on ascorbic acid and total acidity content, sweetness, colour, juiciness, sourness, aroma and firmness of the mango fruits.

Star fruit (Averrhoa carambola) is commonly consumed as a herbal remedy for various ailments in tropical countries. However, the dangers associated with consumption of star fruit are not commonly known. Although star fruit induced oxalate nephrotoxicity in those with existing renal impairment is well documented, reports on its effect on those with normal renal function are infrequent. We report two unique clinical presentation patterns of star fruit nephrotoxicity following consumption of the fruit as a remedy for diabetes mellitus-the first, in a patient with normal renal function and the second case which we believe is the first reported case of chronic kidney disease (CKD) due to prolonged and excessive consumption of star fruits. The first patient is a 56-year-old female diabetic patient who had normal renal function prior to developing acute kidney injury (AKI) after consuming large amount of star fruit juice at once. The second patient, a 60-year-old male, also diabetic presented with acute on chronic renal failure following ingestion of a significant number of star fruits in a short duration with a background history of regular star fruit consumption over the past 2-3 years. Both had histologically confirmed oxalate induced renal injury. The former had histological features of acute tubulo-interstitial disease whilst the latter had acute-on-chronic interstitial disease; neither had histological evidence of diabetic nephropathy. Both recovered over 2 weeks without the need for haemodialysis. These cases illustrate the importance of obtaining the patient's detailed history with respect to ingestion of herbs, traditional medication and health foods such as star fruits especially in AKI or CKD of unknown cause.

This experiment was carried out to investigate the effects of bagging materials and CaCl 2 spray on fruit Ca concentration in fruit-bagged apple trees (Malus domestica Borkh.). No difference was noted in fruit Ca concentration among bagging materials during the growing season. And also, there was no difference in fruit Ca concentration between bagged and non-bagged fruits. The fruit flesh Ca concentration of bagged fruits was significantly lower than that of non-bagged fruits in the same tree, which 0.5 % CaCl 2 was sprayed 5 times in the late growing season. The radioactivity of 45 Ca was highest in the sprayed shoot leaves and bark, while only a trace amount was detected in the fruit and shoot proximate to the treated shoot 3 weeks after 3 times application of 45 CaCl 2 (5 micro Ci/ml). As a result, it is confirmed that the Ca once accumulated in a specific part is hardly retranslocated. Therefore, it is concluded that Ca foliar spray to the fruit-bagged tree has no influence on Ca concentration in the fruit

The fungus Colletotrichum gloeosporioides breaches the fruit cuticle but remains quiescent until fruit ripening signals a switch to necrotrophy, culminating in devastating anthracnose disease. There is a need to understand the distinct fungal arms strategy and the simultaneous fruit response. Transcriptome analysis of fungal-fruit interactions was carried out concurrently in the appressoria, quiescent and necrotrophic stages. Conidia germinating on unripe fruit cuticle showed stage-specific transcription that was accompanied by massive fruit defense responses. The subsequent quiescent stage showed the development of dendritic-like structures and swollen hyphae within the fruit epidermis. The quiescent fungal transcriptome was characterized by activation of chromatin remodeling genes and unsuspected environmental alkalization. Fruit response was portrayed by continued highly integrated massive up-regulation of defense genes. During cuticle infection of green or ripe fruit, fungi recapitulate the same developmental stages but with differing quiescent time spans. The necrotrophic stage showed a dramatic shift in fungal metabolism and up-regulation of pathogenicity factors. Fruit response to necrotrophy showed activation of the salicylic acid pathway, climaxing in cell death. Transcriptome analysis of C. gloeosporioides infection of fruit reveals its distinct stage-specific lifestyle and the concurrent changing fruit response, deepening our perception of the unfolding fungal-fruit arms and defenses race. © 2014 The Authors.

Stpiczynska, M.; Nepi, M.

2005-01-01

Full text: The production and secretion of nectar has an energy cost that can be a substantial part of the energy economy of the plant. Plants may therefore recover part of the energy allocated to nectar secretion by reabsorbing nectar not collected by pollinators. This energy-saving strategy has been demonstrated by several authors by different methods. Here we demonstrate nectar reabsorption and sugar translocation in Cucurbita pepo by means of microautoradiography. Our results confirm that the dynamics of nectar reabsorption is different in male and female flowers. Differences in the dynamics of nectar reabsorption and sugar translocation were also found in pollinated and unpollinated female flowers. Pollinated female flowers reabsorbed sugar very quickly and translocated it to developing fruits in which ovules were the main sugar sink. Sugar translocation was slower and ovules did not label in unpollinated female flowers. (author)

2017-04-01

Full Text Available Dry fruits are some of the essential foods a human body requires staying healthy. They are made after extracting water from them. These fruits are full of essential nutrients including minerals, vitamins, enzymes, fibers and protect the body from a number of different adversities. These fruits are also a source of healthy nutrition among diabetic people who are very concerned about what to eat and what not to eat. But besides their countless benefits, these dry fruits can cause a number of harms to the body and therefore, must be used in a balanced way. This article is based on healthy and unhealthy effects of dry fruits and their use in diabetes mellitus.

Gopukumar, N; Manikandan, M; Arivarignan, G

2002-10-01

Development of roosting patterns under a limited resource was studied in the short-nosed fruit bat C. sphinx in captivity. Spatial fidelity during the resting period (day time) and the individual male bat's presence/absence in the roost (occupancy index) were estimated during the active period (night time). Results show the presence of three groups on the basis of spatial fidelity. The first group was associated with the tent consisting of a harem male and seven females. The second group stayed near to the harem. The third group consisting of two males showed little occupancy index and no spatial fidelity. Female turnover between the first and second groups, and harem male replacement were observed. These findings of male groupings and female loyalty on the basis of "resource", suggest that resource defence polygyny is the primary mating strategy in C. sphinx.

Robert J. Cannon

2018-04-01

Full Text Available Global production and demand for tropical fruits continues to grow each year as consumers are enticed by the exotic flavors and potential health benefits that these fruits possess. Volatile sulfur compounds (VSCs are often responsible for the juicy, fresh aroma of tropical fruits. This poses a challenge for analytical chemists to identify these compounds as most often VSCs are found at low concentrations in most tropical fruits. The aim of this review is to discuss the extraction methods, enrichment techniques, and instrumentation utilized to identify and quantify VSCs in natural products. This will be followed by a discussion of the VSCs reported in tropical and subtropical fruits, with particular attention to the odor and taste attributes of each compound. Finally, the biogenesis and enzymatic formation of specific VSCs in tropical fruits will be highlighted along with the contribution each possesses to the aroma of their respective fruit.

Alessandro da Silva Oliveira

Full Text Available ABSTRACT Bahia is the Brazilian state with the largest production of sugar apple fruits (Annona squamosa L., and fruit borer (Cerconota anonella, Sepp. 1830 is a key crop pest. Insecticides are the main strategy for pest control even though there are no pesticides registered for this crop. This study aimed to assess the efficacy of insecticides to control fruit borer and determine the levels of insecticide residues in sugar apple fruits aiming at requesting the extension of authorization to use insecticide products in this crop. The experiment was conducted in an eight-year-old irrigated orchard (2 × 4 m located in Anagé, Bahia, Brazil. The experimental design was a randomized block design with 10 treatments (three insecticides with three doses and a control with water and 5 replications. Each plot was composed of four plants but only the two central ones were assessed. Insecticides and doses (g a.i. 100 L−1 water were Bacillus thuringiensis: 0.8, 1.7, and 2.5; triflumuron: 2.4, 3.6, and 4.8; and imidacloprid: 4.0, 10.0, and 16.0. Nine sprayings were carried out at fortnightly intervals with a costal sprayer with constant pressure, JA-2 nozzle, and with jet directed to the fruits. Ten assessments were performed in order to observe fruit borer presence in 30 previously marked fruits per plot. Imidacloprid, at the highest studied dose, was the only effective treatment. Analyses of imidacloprid residues, at 21 and 30 days after the highest dose application, indicated levels higher than the maximum limit allowed. Insecticides under the conditions tested do not meet the norms for requesting the extension of authorization to use insecticides for citrus in sugar apple fruits.

The MADS-box family of genes has been shown to play a significant role in the development of reproductive organs, including dry and fleshy fruits. In this study, the molecular properties of an AGAMOUS like MADS box transcription factor in banana cultivar Giant governor (Musa sp, AAA group, subgroup Cavendish) has been elucidated. We have detected a CArG-box sequence binding AGAMOUS MADS-box protein in banana flower and fruit nuclear extracts in DNA-protein interaction assays. The protein fraction in the DNA-protein complex was analyzed by mass spectrometry and using this information we have obtained the full length cDNA of the corresponding protein. The deduced protein sequence showed ∼95% amino acid sequence homology with MA-MADS5, a MADS-box protein described previously from banana. We have characterized the domains of the identified AGAMOUS MADS-box protein involved in DNA binding and homodimer formation in vitro using full-length and truncated versions of affinity purified recombinant proteins. Furthermore, in order to gain insight about how DNA bending is achieved by this MADS-box factor, we performed circular permutation and phasing analysis using the wild type recombinant protein. The AGAMOUS MADS-box protein identified in this study has been found to predominantly accumulate in the climacteric fruit pulp and also in female flower ovary. In vivo and in vitro assays have revealed specific binding of the identified AGAMOUS MADS-box protein to CArG-box sequence in the promoters of major ripening genes in banana fruit. Overall, the expression patterns of this MADS-box protein in banana female flower ovary and during various phases of fruit ripening along with the interaction of the protein to the CArG-box sequence in the promoters of major ripening genes lead to interesting assumption about the possible involvement of this AGAMOUS MADS-box factor in banana fruit ripening and floral reproductive organ development.

Fruit is an important food resource for neotropical primates. In this study I compare the fruit diet of sympatric brown howlers (Alouatta guariba) and southern muriquis (Brachyteles arachnoides). Feeding behavior was studied over 12 months and fruit species consumed were identified and assigned to the categories fruit type, fruit color, and seed size. Observed-fruit feeding records were compared with expected records determined from local availability of the fruit of the tree species. I also determined dietary overlap. Fruit consumption occupied 8 and 12% of the feeding time of A. guariba and B. arachnoides, respectively. Fruit from eight tree species were consumed by the former and fruit from twenty-two species by the latter. Patterns of fruit selection of A. guariba and B. arachnoides varied widely. Although howlers and muriquis converge behaviorally by selecting fruit with common attributes (fleshy/unprotected, violet and brown/black-colored), unlike A. guariba, B. arachnoides fed on immature seeds of fleshy/protected and dry fruit. Large seeds were ingested, and defecated intact, by B. arachnoides only. There was little overlap of fruit diet even within categories that had been selected by both, suggesting that dietary divergence is occurring at the interspecific level. Different resource exploitation probably mediates the coexistence of A. guariba and B. arachnoides in low diversity, semideciduous forests, where the environment imposes narrow limits on primate food choices.

Fruits and vegetables are universally promoted as healthy. The Dietary Guidelines for Americans 2010 recommend you make one-half of your plate fruits and vegetables. Myplate.gov also supports that one-half the plate should be fruits and vegetables. Fruits and vegetables include a diverse group of plant foods that vary greatly in content of energy and nutrients. Additionally, fruits and vegetables supply dietary fiber, and fiber intake is linked to lower incidence of cardiovascular disease and obesity. Fruits and vegetables also supply vitamins and minerals to the diet and are sources of phytochemicals that function as antioxidants, phytoestrogens, and antiinflammatory agents and through other protective mechanisms. In this review, we describe the existing dietary guidance on intake of fruits and vegetables. We also review attempts to characterize fruits and vegetables into groups based on similar chemical structures and functions. Differences among fruits and vegetables in nutrient composition are detailed. We summarize the epidemiological and clinical studies on the health benefits of fruits and vegetables. Finally, we discuss the role of fiber in fruits and vegetables in disease prevention. PMID:22797986

At the Institute of Fruit Growing, Plovdiv, triple buds were grafted on the crowns of 6 year-old peach trees in the following cultivar combinations: 1. Springtime (early8 ripening in the second half of June, white fleshed) on Rio oso gem (late, ripening in the first half of September, yellow fleshed); 2. Fillette (early, ripening in the second half of June, yellow fleshed) on Rio oso gem; 3. Rio oso gem on Springtime; 4. Rio oso gem on Fillette. At the begining of the following growing period the development of the grafted generative organs was fully dependent on assimilates produced by the leaves of the other cultivar. The interrelations between the leaves and the fruits in the various combinations were followed by biometrical and radio-isotopic ( 14 C) methods. Results substantiated the conclusion that the genetic information on the development of the specific cultivar characters such as flavour, arome, skin colour, fruit flesh texture and colour, fruit size and date of ripening was borne by the fruits themselves. The synthetic processes of the leaves during photosynthesis are not directly related with the synthetic processes producing the fruits' organic matter. The basic constructing substances were produced in the leaves and were transported to the fruits, where they were subjected to metabolic transformations in accordance with the biological characteristics of the cultivar and the phase of fruit development

It is said that the backbone of Indian economy is agriculture. The contribution of the agriculture sector to the national GDP (Gross Domestic Products) was 14.6% in the year 2010. To attain a growth rate equivalent to that of industry (viz., about 9%), it is highly mandatory for Indian agriculture to modernize and use automation at various stages of cultivation and post-harvesting techniques. The use of computers in assessing the quality of fruits is one of the major activities in post-harvesting technology. As of now, this assessment is majorly done manually, except for a few fruits. Currently, the fruit quality assessment by machine vision in India is still at research level. Major research has been carried out in countries like China, Malaysia, UK, and Netherlands. To suit the Indian market and psychology of Indian farmers, it is necessary to develop indigenous technology. This paper is the first step toward evaluating the research carried out by the research community all over world for tropical fruits. For the purpose of survey, we have concentrated on the tropical fruits of the state of Maharashtra, while keeping in focus of the review image processing algorithms.

The relationships between vertebrate pests and crop damage are often complex and difficult to study. In palm oil plantations rodents remain the major pests, causing substantial monetary losses. The present study examined the numerical and functional responses of rodents to changes in the availability of oil palm fruit and the damage associated with that response. For the study, 200 traps were set in pairs on a 10 × 10 trapping grid for 3 consecutive nights in each of 6 study plots at 8-week intervals in a 2569 ha oil palm plantation at Labu, Negeri Sembilan state in Peninsular Malaysia over 14 months. A total of 1292 individual rats were captured over 25 200 trap-nights. Animals were identified, aged, sexed, weighed and measured. An index of the relative abundance of rats was calculated based on trapping success. Damage to infructescences was assessed at each trap point. Regardless of the age of palms, there were positive and significant relationships between the relative abundance of rats and numbers of infructescences. The levels of damage to infructescences were significantly correlated with the relative abundance of rats. A steep increase in damage was observed with an increase in mature infructescences, indicating a feeding preference of rats for mature infructescences. For both males and females of all rat species, there were weak and non-significant correlations between body condition and infructescence numbers. These results indicated that there was a numerical and a functional response by rats to the availability of palm fruit and a resulting increase in depredation of oil palm fruits. The ways in which this information might aid in future pest control are discussed. © 2011 ISZS, Blackwell Publishing and IOZ/CAS.

At ripening fruits undergo many changes which include the development of color and aroma and improvements in flavor and texture that make them attractive to potential consumers. Fruits provide an important source of health-related substances, plus minerals and vitamins, and the quality of a fruit is influenced by variety, nutritional status, and environmental conditions during plant growth and fruit development. Ripening is considered to be the main process in fruit development, and all studies had been focused on this process which included physicochemical, biochemical, and molecular analysis. With the development of genomic analysis the strategies to study fruit ripening have been changing and now there are new perspectives and opportunities. The objective of this review is to describe the state of the art in the studies related to fruit ripening with emphasis in molecular studies.

Barth, Margaret; Hankinson, Thomas R.; Zhuang, Hong; Breidt, Frederick

Consumption of fruit and vegetable products has dramatically increased in the United States by more than 30% during the past few decades. It is also estimated that about 20% of all fruits and vegetables produced is lost each year due to spoilage. The focus of this chapter is to provide a general background on microbiological spoilage of fruit and vegetable products that are organized in three categories: fresh whole fruits and vegetables, fresh-cut fruits and vegetables, and fermented or acidified vegetable products. This chapter will address characteristics of spoilage microorganisms associated with each of these fruit and vegetable categories including spoilage mechanisms, spoilage defects, prevention and control of spoilage, and methods for detecting spoilage microorganisms.

Gamma irradiation of fruits

International Nuclear Information System (INIS)

Beyers, M.

1983-08-01

At a Joint FAO/IAEA/WHO Expert Committee on Food Irradiation (JECFI) meeting held in 1976, recommendations were made to rationalize the unnecessarily elaborate wholesomeness evaluation procedures for irradiated foodstuffs. Irradiation at the commercially recommended doses did not adversely affect the constituents of mangoes, papayas, litchis and strawberries at the edible-ripe stage. These favourable radiation-chemical results justified the development of a theoretical model mango which could be used for extrapolation of wholesomeness data from an individual fruit species to all others within the same diet class. Several mathematical models of varying orders of sophistication were evolved. In all of them, it was assumed that the radiant energy entering the system reacted solely with water. The extent of the reaction of the other components of the model fruit with the primary water radicals was then determined. No matter which mathematical treatment was employed, it was concluded that the only components which would undergo significant modification would be the sugars. In order to extrapolate these data from the mango to other fruits, mathematical models of three fruits containing less sugar than the mango, viz. the strawberry, tomato and lemon, were compiled. With these models, the conclusion was reached that the theoretical degradation spectra of these fruits were qualitatively similar to the degradation pattern of the model mango. Theory was again substantiated by the practical demonstration of the protective effect of the sugars in the tomato and lemon. The decrease in radiation damage was enhanced by the mutual protection of the components of the whole synthetic fruits with ultimate protection being afforded by the biological systems of the real fruits

Full Text Available A study was undertaken to characterize and manage pathogens associated with fruit rot of immature cucumber fruits in greenhouses in Oman. A survey over 5 growing seasons from 2008 to 2010 in 99 different greenhouses in Oman showed that the disease is prevalent in 91 (92% greenhouses and results in losses of 10 to 60% (avg. 33% of immature fruits per plant. Incidence of the disease was not found to be affected by growing seasons, which could be attributed to the limited fluctuations in ambient temperatures in greenhouses. Isolations from diseased cucumber fruits yielded Alternaria alternata (isolation frequency = 52%, Fusarium equiseti (40%, Cladosporium tenuissium (27%, Botrytis cinerea (6%, Fusarium solani (6%, Corynespora cassiicola (3%, Aspergillus spp. (2%, Curvularia sp. (1% and Bipolaris sp. (1%. With the exception of Curvularia and Bipolaris species, all other fungi were pathogenic on cucumber fruits, with Fusarium equiseti being the most aggressive, followed by Corynespora cassiicola, Botrytis cinerea and Alternaria alternata. Cladosporium and Aspergillus spp. were found to be weakly pathogenic. Comparing the efficacy of foliar and soil applications of carbendazim fungicide on fruit rot of cucumber showed that foliar applications significantly reduced fruit rot and increased cucumber yield when compared to soil application or to control (P < 0.01. This appears to be the first report of the association of Corynespora cassiicola and Fusarium equiseti with fruit rot of immature greenhouse cucumbers. This is also the first report in Oman for the association of Cladosporium tenuissimum with fruit rot of immature cucumbers. Findings are discussed in terms of factors affecting disease control in greenhouses using carbendazim.

The present study was carried out in order to detect the irradiated fruits and assess the quality parameters of plums (Prunus domestica L., cv. Pioneer) and peaches (Prunus persica Bausch, cv. Swilling) fruits treated with gamma irradiation. This investigation was carried out during 2010 and 2011 seasons. The fruits were harvested at commercial maturity, irradiated with the doses 0.50, 0.75 and 1.0 kGy, stored under refrigerated conditions (0±1°C, RH 80%) then evaluated at intervals of 7, 10 and 21 days (the end cold storage period) followed by 5 days of storage under market condition (20±2°C, RH 80%). Electron spin resonance (ESR) was carried out for determination of free radicals by using dried layers of plum and peach kernels. Fruit characters included weight loss %, fruit firmness (kgf), discarded fruits %, soluble solid contents (SSC, ºBrix), total titratable acidity (TA%), respiration rate and sensory evaluation tastes. ESR results proved the possibility of identification of irradiated fruits by using dried stone kernels. The results showed that ESR intensities were sensitive for all applied doses even at low doses of 0.5 or 1.0 kGy which was applied for dis infestations, to extend the shelf-life of fruits or to detect the irradiated stored fresh samples was carried out at the 7th, 10th and 21st days. The linear relationship resulted between ESR intensity and applied doses showed high significant correlation coefficient (R2) for the irradiated samples. However, ESR intensity was decreased gradually during long storage period but can identify clearly the irradiated samples. Irradiation treatment at 0.5 kGy for P ioneer p lums and at 0.5 or 0.75 kGy for S willing p eaches was effective in slowing the rate of losing of fruits weight and decreasing the discarded fruits percentage. Furthermore, it has significant effects on reducing respiration rate, maintaining higher soluble solid contents and decreasing total titratable acidity. Referring to sensory

Full Text Available Abstract Background The workplace has been identified as an ideal setting for health interventions. However, few UK-based workplace intervention studies have been published. Fewer still focus on the practicalities and implications when running an intervention within the workplace setting. The objective of this paper was to qualitatively determine the perceived behaviour changes of participants in a free fruit at work intervention. Understanding the dynamics of a workplace intervention and establishing any limitations of conducting an intervention in a workplace setting were also explored. Methods Twenty-three face-to-face interviews were conducted with individuals receiving free fruit at work for 18 weeks (74 % female. The worksite was the offices of a regional local government in the North East of England. Analysis was guided theoretically by Grounded Theory research and the data were subjected to content analysis. The transcripts were read repeatedly and cross-compared to develop a coding framework and derive dominant themes. Results Topics explored included: the workplace food environment; the effect of the intervention on participants and on other related health behaviours; the effect of the intervention on others; participant’s fruit consumption; reasons for not taking part in the intervention; expectations and sustainability post-intervention; and how to make the workplace healthier. Five emergent themes included: the office relationship with food; desk based eating; males and peer support; guilt around consumption of unhealthy foods; and the type of workplace influencing the acceptability of future interventions. Conclusion Exploring the perceptions of participants offered valued insights into the dynamics of a free fruit workplace intervention. Findings suggest that access and availability are both barriers and facilitators to encouraging healthy eating in the workplace.

Full Text Available The spatiochromatic properties of the red–green dimension of human colour vision appear to be optimized for picking fruit in leaves at about arms' reach. However, other evidence suggests that the task of spotting fruit from a distance might be more important. This discrepancy may arise because the task a system (e.g. human trichromacy is best at is not necessarily the same task where the largest advantage occurs over the evolutionary alternatives (dichromacy or anomalous trichromacy. We tested human dichromats, anomalous trichromats and “normal” trichromats in a naturalistic visual search task in which they had to find fruit pieces in a bush at 1, 4, 8 or 12 m viewing distance. We found that the largest advantage (in terms of either performance ratio or performance difference of normal trichromacy over both types of colour deficiency was for the largest viewing distance. We infer that in the evolution of human colour vision, spotting fruit from a distance was a more important selective advantage than picking fruit at arms' reach.

The results of measurements carried out during the period 1987-1988, to evaluate the levels of 137 Cs and 134 Cs contamination in fruit samples and in various components of fruit-trees have been reported. It has been demonstrated that, in the case of an accidental contamination of the air, the contamination of fruit is mainly due to the foliar translocation of radionuclide. Data of radioactivity content in fruits collected through a period of three years show that the radioactivity content in fruit diminishes exponentially. Rough estimates of ''translocation coefficient'' defined as the ratio (radionuclide concentration in fruit)/(radionuclide deposition on soil), and of the ''biological half time'' have been carried out in the case of hazel-nut, walnut, apple, chestnut and olive

Regularities in the supply of young peach fruits with 14C assimilates within a fruit-bearing branchlet

A well expressed independence may be observed in nurturing young fruits of the Rio Ozo Gem variety with newly produced 14 C assimilates within a fruit-bearing branchlet. For an effective link between the individual lateral shoots and fruits both their around location and linear nearness to each other are of importance. Since the phloem fibre direction within several internaodes is nearly parallel to the branchlet axis, as a rule fruits are supplyed by the shoots situated on the same branchlet side. The negative influence of the distance between fruit and shoot is due mainly to the competition of near fruits located on the same phloem strip. Under the complex effect of these factors certain specialization is formed of the shoots arranged along the fruit-bearing branchlet, namely the upper shoots do service mainly to the upper part and the bottom ones to the basic part of it. At the same time, shoot removal tests showed that the said independence is not absolute in the carbohydrate nurture of the young fruits within the fruit-bearing branchlet. The function of an absent donor organ (a shoot) is taken over in this case by other donor organs to a greater degree than in a vegetative growth even if it would be exigently to go over from a longitudinal to a transversal transport. This shows that the young peach fruits about a month after blossoming have a greater mobilizing strength than the young growing leaves. (author)

Full Text Available Abstract Background Based on recent studies in Israel demonstrating that attractive toxic sugar bait (ATSB methods can be used to decimate local anopheline and culicine mosquito populations, an important consideration is whether the same methods can be adapted and improved to attract and kill malaria vectors in Africa. The ATSB approach uses fruit or flower scent as an attractant, sugar solution as a feeding stimulant, and an oral toxin. The ATSB solutions are either sprayed on vegetation or suspended in simple bait stations, and the mosquitoes ingesting the toxic solutions are killed. As such, this approach targets sugar-feeding female and male mosquitoes. This study examines the attractiveness of African malaria vectors to local fruits/seedpods and flowering plants, key biological elements of the ATSB approach for mosquito control. Methods Three field experiments were conducted at sites in Mali. The attraction of Anopheles gambiae s.l. to 26 different local fruits and seedpods was determined at a site in the semi-arid Bandiagara District of Mali. Wire mesh glue traps with fruits/seedpods suspended on skewers inside were set along a seasonal lagoon. Seven replicates of each fruit/seedpod species were tested, with a water-soaked sponge and a sugar-soaked sponge as controls. The attraction of An. gambiae s.l. to 26 different types of flowering plants was determined at a site near Mopti in Mali. The flowering plants held in a water-filled buried container were tested using the same glue traps, with controls including water only and sugar solution. Six replicates of each selected plant type were tested on transects between rice paddies. Additional studies using CDC light traps were done to determine the relative densities and periodicity of An. gambiae s.l. attraction to branches of the most highly attractive flowering plant, branches without flowers, human odor, and candescent light. Results Of the 26 fruits and seedpods tested, 6 were attractive
