    The chemical analysis of the elemental compositions of both males and females of the Mediterranean fruit fly, Ceratitis capitata (Wied.), was conducted on adult flies irradiated in the full grown pupae with 50, 70, 90 and 110 Gray at different ages (newly emerged, 7 and 15 days old). The data revealed the presence of ten elements, three of which are major (Na, K and N), four are moderate (P, Ca, Fe and Mg) and three are minors (Zn, Mn and Cu). Their quantities, however, varied according to adult sex, age and radiation dose. In all cases, the major elements remained major, the moderate elements remained moderate and the minor elements remained minor although the elements of each group differed in their arrangement according to changes in their quantities

    The Mediterranean Fruit Fly (Medfly, Ceratitis capitata), widespread in most tropical and subtropical area, lays eggs under the skin of fruit. Its larvae feed on the pulp, causing tremendous losses for agriculture. Insecticides, besides being hazardous for the environment, have proven too slow for effective pest control (eradication in 20 generations). This training film demonstrates in 7 detailed steps how the Sterile Insect Technique (SIT) can lead to elimination of the insect population within 6 generations. It shows different stages of breeding and describes the sterilization of pupae by exposure to gamma rays provided by a cobalt 60 source

    Full Text Available Plant essential oils (EOs and a wide range of their individual components are involved in a variety of biological interactions with insect pests including stimulatory, deterrent, toxic and even hormetic effects. Both the beneficial and toxic properties of citrus EOs on the Mediterranean fruit fly (medfly have been experimentally evidenced over the last years. However, no information is available regarding the toxic or beneficial effects of the major components of citrus EOs via contact with the adults of the Mediterranean fruit fly. In the present study, we explored the toxicity of limonene, linalool and α-pinene (3 of the main compounds of citrus EOs against adult medflies and identified the effects of sub-lethal doses of limonene on fitness traits in a relaxed [full diet (yeast and sugar] and in a stressful (sugar only feeding environment. Our results demonstrate that all three compounds inferred high toxicity to adult medflies regardless of the diet, with males being more sensitive than females. Sub-lethal doses of limonene (LD20 enhanced the lifespan of adult medflies when they were deprived of protein. Fecundity was positively affected when females were exposed to limonene sub-lethal doses. Therefore, limonene, a major constituent of citrus EOs, induces high mortality at increased doses and positive effects on life history traits of medfly adults through contact at low sub-lethal doses. A hormetic-like effect of limonene to adult medflies and its possible underlying mechanisms are discussed.

    To improve the sterile insect technique for controlling the Mediterranean fruit fly, Ceratitis capitata (Wied.), experiments were carried out to test the effect of four new adult protein sources on the insect vitality. Different yeasts consisting of almost the same nutritive components but differ in the quantity of protein were mixed with sugar as carbohydrate sources (2:3) and compared to the standard adult diet (enzymatic yeast hydrolysate : sugar, 1:3). Adults reared on each diet were evaluated biologically for their response to gamma radiation (90 Gy). The weight and size of the produced pupae from parents fed on the tested diets, percent of adult emergence, sex ratio, adults survival, egg hatchability and male mating competitiveness value (C.V.) for the following generations were taken as monitors for the insect vitality. The results showed that adult male and female survival for 5, 10 and 15 days from emergence, percent egg hatchability and male mating competitiveness value (C.V.) showed no sharp differences between three tested diets D3(Af), D4(YE300) and D5(YE00) as compared to the standard diet D1(YH, enzymatic yeast hydrolysate : sugar, 1:3) for parents and F1 progeny. However, when the second tested diet D2(Ay150) was used, the results showed a significant decreases in most of the tested biological aspects, especially in the male mating competitiveness value (C.V.), which is considered the most important monitor for male insect vitality

    Eight botanic odours were evaluated for their attractability to the mediterranean fruit fly, ceratitis capitata wied. out of these attractants four showed good attractability to males (55-67%). These are orange, bitter orange, mandarin and basil. However, peach, apricot, apple and lemon showed much less attractability to males (16-28%). All of these odours were male-specific and their attractability to females was very limited (1-4%). Population densities outside the trap did not clearly affect attractability except in case of mandarin odour which attracted more flies at high population densities than at lower ones. Sex ratio outside the trap did not significantly affect the odour attractability to flies in all cases

    Mass rearing conditions affect the mating behavior of Mediterranean fruit flies (medflies) Ceratitis capitata (Wiedemann). We evaluated the effect of slight changes in the adult holding conditions of adult flies maintained for egg production on their mating performance. Colonization was initiated from wild flies collected as larvae from infested coffee berries (Coffea arabica L.). When pupae were close to adult emergence, they were randomly divided into 3 groups and the emerging adults were reared under the following conditions: (1) Metapa System (MS, control), consisting of 70 x 45 x 15 cm aluminum frame, mesh covered cages, with a density of 2,200 flies per cage and a 1:1 initial sex ratio; (2) Insert System (IS), with the same type of cage, and the same fly density and sex ratio as in the MS treatment, but containing twelve Plexiglas pieces (23 x 8.5 cm) to provide additional horizontal surface areas inside the cage; and (3) Sex-ratio System (SS), same as IS, but in this case the initial male: female ratio was 4:1. Three d later, newly emerged females were introduced, so the ratio became 3:1 and on the 6th d another group of newly emerged females was added to provide a 2:1 final sex ratio, at which the final density reached 1,675 flies per cage. The eggs collected from each of the 3 treatments were reared independently following standard procedures and the adults were held under the same experimental conditions. This process was repeated for over 10 to 13 generations (1 year). The experiment was repeated 3 times in 3 consecutive years, starting each replicate with a new collection of wild flies. Life tables were constructed for each treatment at the parental, 3rd, 6th, and 9th generations. Standard quality control parameters (pupation at 24 h, pupal weight, adult emergence, and flight ability), were estimated for each treatment every third generation in the third year. For the last generation each year, mating competitiveness was evaluated in field cage tests

    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.

    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.

    The effect of the using eight different artificial adult diets of the mediterranean fruit fly, ceratitis capitata (Wied.) on egg and larval production was studied. Adults fed on complete homogenate diet consisting of 75% raw sugar 25% yeast hydrolysate, showed a slightly insignificant decrease in the number of eggs and larvae produced/ female/ day. In absence of yeast hydrolysate, adults offered either only pure or raw sugar, showed a drastically significant decrease in both the number of eggs laid and larvae produced by one female/day. On the other hand, when the protein source was offered as a mixture of yeast hydrolysate and commercial yeast in the ratio 1:1 and offered pure or raw sugar as a carbohydrate source, the egg and larval production were almost not affected. Moreover, when the protein source was offered as totally commercial yeast and using pure or raw sugar as a carbohydrate source at the ratio 1:3, egg and larval production were highly significantly reduced. The results showed that, the 3 diets producing the highest number of eggs and larval/female/day were that consisting of raw sugar and yeast hydrolysate at the ratio 3:1 as well as those consisting of raw sugar and yeast hydrolysate and commercial yeast at the ratio 6:1:1. these 3 diets showed almost no effect on neither pupal or adult production nor sex ratio compared to control diet

    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.

Medfly adults were monitored weekly all year around using Jackson traps baited with trimedlure dispensers. Larvae were also sampled in Damascus Ghota by collecting fruits from ripe or ripening fruit trees and recording the number of larvae emerged from these fruits. In addition, suspected overwintering refuges were sampled at weekly intervals during the three coldest months of the year (December – February and the number of collected larvae was recorded. The results of trap catches and fruit sampling studies showed a similar pattern of occurrence of medfly populations in the study areas, particularly in Damascus Ghota, during the three years of the study. In Damascus Ghota, flies were caught continuously from early June to late December with some variability between years. Two distinct periods of high fly activity were observed: the first one occurred in August and the second in November with a much higher amplitude. In general, seasonal fluctuations in the pattern of occurrence were influenced by differences in temperature and abundance of preferred host fruits. Traps on fig Ficus carica and oriental persimmon Diospyros kaki trees caught the highest numbers of flies, and fruits collected from these trees showed the highest level of infestation, reaching 100% for fig fruit late in the season. Sampling fruits (in Damascus Ghota from trees during the three coldest months of the year showed that a small population of medfly larvae was able to survive winter conditions in prickly pear Opuntia vulgaris fruit left on the trees. In the other areas of the study (Zabadani, Sargaiah, Rankus, Orneh and Ain Al-Arab, only a few flies were caught.

    Various methods of controlling the medfly are available and include the use of insecticides, bait sprays and the sterile insect technique (SIT). Each of these control strategies may be used alone or in sequence. With regard to the application of the SIT, the Joint FAO/IAEA Division of Atomic Energy in Food and Agriculture through its Insect and Pest Control Section and Entomology Laboratory is in an excellent position to assist in containing the medfly in Central America. For the past 12 years, the laboratory has participated in all phases of medfly control by sterile insect releases in various climates. This involvement has included planning of medfly campaigns, development of pre-release techniques (bait spraying, trapping, etc.) and shipment and release of sterilized medflies. Small-scale field tests utilizing the SIT have been carried out by nine countries: Italy (Procida, Capri), Spain, Cyprus, Israel, Tunisia, Peru, Panama, Costa Rica and Nicaragua. Other field projects presently being counselled and serviced are located in Argentina, Venezuela and the Canary Islands. The research and development that are still needed to effectively stabilize and gain control of the medfly situation in Central America include: The development and use of effective quarantine procedures in various countries; Development of effective conventional medfly control procedures under the conditions found in Central America; Development of methods to determine the geographic origin of medflies introduced into new areas; Medfly mass production (viz. all aspects of rearing Central American strains); Assessing the performance (competitiveness, etc.) of various strains; Logistics, including the development of systems for releasing pre-adult stages; Genetic rearing methods: developmental research in this area is particularly promising since the preferential production of males would allow considerable savings in the rearing costs of medflies for release; Development of adequate surveillance

    The genetic structure of 15 wild populations of Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann), sampled from different geographical areas and different host fruit tree species, has been studied. Each population was analysed for 25 enzyme systems detected electrophoretically. All the Mediterranean populations proved to be highly monomorphic (H-bar=0.053) whereas those from South Africa and Reunion were highly heteromorphic (H-bar=0.234 and 0.153 respectively). As the urea denaturation method was used, no hidden genetic variability caused by the usual electrophoretic conditions was detected. The most probable explanation of the low genetic variability observed in the introduced populations of the medfly seems to be the historical reasons, namely the time elapsed since colonization and the number of individuals of the founder population. Experiments in the field and in the laboratory failed to detect any pattern of preference for oviposition sites in the medfly populations. More specifically, the differences in allele frequencies for the polymorphic loci among these populations do not seem to be correlated either with the taxonomic status of the host fruit or with the size of the fruit. It is concluded that the medfly as a fine grained species may utilize many alternative food resources without an apparent action of selection (or at least one that is detectable by the methods used). By estimating the genetic distances between the populations and/or by using the allozymes as genetic markers the route(s) of dispersion of the fly from its geographic centre of origin, which is placed in Africa, could be roughly traced. Finally, no systematic changes in allele frequencies were observed in populations reared on artificial substrate. (author). 43 refs, 2 figs, 9 tabs

    In the recent years the mediterranean fruit fly, Ceratitis capitata distributed in the orchards of central Iraq and caused highly economic losses. This study was conducted in orchards in South Baghdad during 2009 and 2010 and made field survey of the insect in four types of orchards (Citrus, Apricot, Figs and Citrus and A mixture of fruit trees) and used for this purpose tephri traps supplied with Q-Lure and dimethyl dichlorovinyl phosphate (DDVP). The present preliminary study has shown that the Mediterranean fruit fly C.capitata has a year round presence in fruit orchards in central Iraq and reached its highest numerical density of the pest in citrus orchards during November and December were 345 and 363 insect / Trap per month in citrus orchards and the least numerical density during of January and February while the highest numerical density of the insect in orchards of orchards of apricot in Mrch 2010, Figs and Citrus in August 2009 and a Mixture of fruit trees in November 2009 were 45, 116, 311 Insect/ trap per month respectively. The population density of the pest was highest beginning 2010 compared with 2009 , but the high temperature degree (46 - o 5 2) in August 2010 caused a decrease in population density of this pest. C.capitata caused highly economic losses in citrus reaching 68, 71, 82% of the Mandarin, Kaki, Apricot fruits respectively. Currently in Iraq no control method to reduce the economic losses caused by this pest except the use of pesticides GF-120. Therefore, results of this study could be of benefit for orcharch owners when applying an integrated program for controlling fruit fly pests. (Author)

    The Government of Tunisia, U. S. Agency for International Development, and U. S. Department of Agriculture cooperatively developed a program for suppression of Ceratitis capitata (Wiedemann) in Tunisia. Mediterranean fruit flies were reared on an artificial diet, sterilized with 10 krad irradiation from a cobalt source, and the emerged adults were marked and then distributed by hand throughout the release area, 600 ha in the vicinity of Porto-Farina. Some aerial releases were made late in the season. Winter larval hosts were removed to lower the overwintering population, and sterile fly releases were begun early (Mar.1) to prevent fertile matings of flies that emerged during warm winter days. All fruit on the periphery of the release area was sprayed periodically (5 applications), as was the major fruit-growing areas within the region but outside the test zone, to minimize the possibility of fertile flies entering the release area. Daily from March to November, ca. 1,000,000 sterile flies were released. Trap catches indicated that the suppression obtained was about equal to that obtained using poison bait sprays. The early preferred host crops had no or negligible infestation (loquats, apricots, early peaches, and figs). The infestation of preferred summer fruits (peaches and figs) was reduced but not controlled. Less susceptible summer fruits were seldom infested. The estimated population was ca. 82.3 percent lower than in the previous year when no releases were made. Isolation and sterile fly distribution was inadequate to completely suppress the Mediterranean fruit fly population. (U.S.)

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.

    Full Text Available Mediterranean fruit fly (Ceratitis capitata Wiedemann is a regular pest of large number of cultivated and wild host plants in Dalmatia. However, this pest does not develop either inside fruits of cultivated olive - Olea europaea sativa or wild olive „ mastrinka“ - Olea europaea oleaster. The main objective of this research was to prove regular presence, time of appearance and flight duration of the Mediterranean fruit fly inside selected orchards of central Dalmatia. During the four years of research, from 2001 to 2004 by using of traps and parapheromone trimedlure, the regular presence of the Mediterranean fruit fly was proved inside four selected orchards on the area of cities of Split and Kaštela, with differences in adult caught between localities and years. During the 2001 year, on the three locations in the area of city of Kaštela, the highest capture during the total research period was recorded, while on the locations in Split, the highest capture was recorded during 2003 year, but also significant during 2001 year. The lowest number of adult, less than 5 flies/trap was captured on all four locations during 2002 year.

    Findings from studies in Western countries showed that Mediterranean diet is inversely associated with metabolic syndrome, but little is known about this association in Asian countries. To evaluate the association between Mediterranean diet and metabolic syndrome in Korean population, this study was conducted. A total of 8387 adults 19-64 years of age from the Korea National Health and Nutrition Examination Survey 2012-2015 were assessed. A 112-item dish-based semiquantitative food frequency questionnaire was used to assess dietary intakes. Mediterranean diet was assessed by a modified Mediterranean diet score, which was based on the alternate Mediterranean diet score of Fung et al. Multivariable logistic regression models were used to calculate odds ratios (ORs) with 95% confidence intervals (CIs) adjusted for other dietary and lifestyle variables. Participants with 5-6 and 7 or higher modified Mediterranean diet scores had a lower prevalence of metabolic syndrome by 27% (OR = 0.73, 95% CI: 0.56-0.96) and 36% (OR = 0.64, 95% CI: 0.46-0.89; P-trend = 0.0031), compared with those with 2 or lower modified Mediterranean diet scores, respectively. Higher modified Mediterranean diet scores were associated with a lower prevalence of abdominal obesity and hypertriglyceridemia, which are components of metabolic syndrome CONCLUSIONS: Our findings suggest that diet rich in fruit, vegetables, whole grains, legumes, peanuts and fish is associated with a lower prevalence of metabolic syndrome in Korean adults.

    A black puparium, monofactorial mutant was isolated in 1983 from a laboratory colony of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann). The mutant was used to construct a genetic sexing strain based on pupal sorting. Translocations were induced in wild male adults, 48 hours old, by gamma radiation (55 Gy; 60 Co). These males were crossed to black pupae females and produced two pupal sorting strains (T-44 and T-213) in 1987. These strains were lost after six generations. In another series of translocation inductions the strain T-87B was screened. Rearing the strain for eight generations in the laboratory provided no indication of instability in the strain. T-87B is now being mass reared. (author). 16 refs, 4 tabs

    The efficiency of wild and irradiated biocontrol fungi, Beauvaria Bassiana (Blsamo) and Trichoderma Harzianum (Rafai) on the Mediterranean Fruit fly Ceratitis Capitata (Wiedemann) was investigated. Applying wild B. bassiana and T. harzianum using spores suspension at different concentrations (10 8 , 10 6 and 10 4 colony-forming units), on the pupation medium (sand) or in drinking water, resulted in a significant reduction in adult emergence of pupae (1-2 day-old) and survival of produced adults. Meanwhile, the introduction of some isolates irradiated at 150 and 300 Gy significantly reduced adult emergence from pupae (1-2 day-old) and survival was greatly increased by isolates irradiated at 150 Gy of B. bassiana and at Gy in case of T. harzianum. Applying irradiated isolates as culture filtrate with the concentrations of 10, 50 and 100% to the pupation medium or in drinking water, resulted in a reduction of adult emergence and survival. The results revealed that bioagents B. bassiana and T. harzianum can be applied in the field to suppress the population of the mediterranean fruit fly ceratitis capitata and considered as entomopathogenic for controlling this pest

    The efficiency of the bacterium pseudomonas fluorescence against the mediterranean fruit fly ceratitis capitata (Wied.) was investigated. Adult emergence was significantly reduced by applying the wild and gamma irradiated strain (150 and 300 Gy). The highest reduction occurred by the mutant P1 and the highest concentration (10 8 ). The activity of this bacteria increased by gamma irradiation compared to that of the wild isolate. The reduction in adult survival of both males and females was highly significant by applying the irradiated bacteria with the two doses of gamma radiation and different concentration (10 8 , 10 6 and 10 4 ) of bacterial suspension. Applying the bacteria as a culture filtrate reduced adult survival of wild strain significantly, while the irradiated strain recorded a significant reduction in males and females with the highest concentration (100 %) and by applying the two doses of gamma radiation (150 and 300 Gy) and in females only at the concentration 50% by using the dose of 150 Gy

  15. Mediterranean fruit fly preventative release programme in southern California

    2000-01-01

    California employs several area-wide pest management programmes that use the release of sterile insects to protect its commercial and dooryard agriculture. The first was developed in response to the discovery of the Mexican fruit fly, Anastrepha ludens, in Tijuana, Mexico and adjacent areas in San Diego County, California. Initially pesticide sprays of malathion and bait were applied to host plants around each fly find site. Additionally, soil sprays of diazion (0.05 kg per 93 m 2 ) were applied under every host plant around each fly find site. It soon became apparent that this approach was expensive and environmentally damaging. This led the interested parties, the California Department of Food and Agriculture (CDFA), the United States Department of Agriculture (USDA) and the government of Mexico to develop a programme that utilises the release of sterile Mexican fruit flies over the city of Tijuana in order to prevent the establishment of a breeding population of this fly in the city. The belief is that preventing the Mexican fruit fly from breeding in Tijuana will help protect both that city and California. To date, no Mexican fruit fly larvae have been found in Tijuana or the adjacent areas of California. The second programme was developed in response to the discovery of the pink bollworm, Pectinophora gossypiella, in cotton in the Imperial Valley area of southern California. As the pink bollworm spread throughout the cotton growing region of southern California, it became a significant pest that threatened the 405,000 hectares of cotton grown in the San Joaquin Valley to the north. To keep this pest out of the San Joaquin Valley, the CDFA/USDA and California cotton growers use the large-scale releases of sterile pink bollworms in areas in which wild pink bollworms are captured each year. Thus far, the pink bollworm has been prevented from establishing a permanent presence in the San Joaquin Valley and the cotton growers in southern California, Arizona and

    Full Text Available The Mediterranean fruit fly, Ceratitis capitata, is one of the most serious pests of fruit crops world-wide. During the last decades, area-wide pest management (AW-IPM approaches with a sterile insect technique (SIT component have been used to control populations of this pest in an effective and environment-friendly manner. The development of genetic sexing strains (GSS, such as the Vienna 8 strain, has been played a major role in increasing the efficacy and reducing the cost of SIT programs. However, mass rearing, extensive inbreeding, possible bottleneck phenomena and hitch-hiking effects might pose major risks for deterioration and loss of important genetic characteristics of domesticated insect. In the present study, we present a modified procedure to cryopreserve the embryos of the medfly Vienna 8 GSS based on vitrification and used this strain as insect model to assess the impact of the cryopreservation process on the genetic structure of the cryopreserved insects. Forty-eight hours old embryos, incubated at 24°C, were found to be the most suitable developmental stage for cryopreservation treatment for high production of acceptable hatch rate (38%. Our data suggest the absence of any negative impact of the cryopreservation process on egg hatch rate, pupation rates, adult emergence rates and stability of the temperature sensitive lethal (tsl character on two established cryopreserved lines (flies emerged from cryopreserved embryos, named V8-118 and V8-228. Taken together, our study provides an optimized procedure to cryopreserve the medfly Vienna 8 GSS and documents the absence of any negative impact on the genetic structure and quality of the strain. Benefits and sceneries for utilization of this technology to support operational SIT projects are discussed in this paper.

    The effects of gamma radiation on the oriental fruit fly, Bactrocera Dorsalis (Hendel), melon fly, Bactrocera Cucurbitae (Coquilett), and Mediterranean fruit fly, Ceratitis Capitata (Weidemann) were studied. Melon fly was determined to be the most susceptible of the three species. A dosage of 550 Gy rendered the eggs 100% sterile when irradiated in papayas at 4-6 hours before hatching. Oriental and mediterranean fruit flies were found to be more resistant, requiring doses of 750 and 850 Gy, respectively. A dose of only 100 Gy was needed to inhibit adult eclosion when the three species were treated at third instar larvae. Warm water treatment at 49 0 C for 20 minutes was found sufficient in preventing the hatching of any egg in the infested papaya fruits. However, since eggs may hatch before the warm-water treatment can be applied, a combination of irradiation treatment using 100 Gy is recommended for disinfestation of papaya fruits.

    Claims abound that the Transvaal red milkwood, Mimusops zeyheri, indigenous to areas with tropical and subtropical commercial fruit trees and fruiting vegetables in South Africa, is relatively pest free owing to its copious concentrations of latex in the above-ground organs. On account of observed fruit fly damage symptoms, a study was conducted to determine whether M. zeyheri was a host to the notorious quarantined Mediterranean fruit fly (Ceratitis capitata). Fruit samples were kept for 16-21 days in plastic pots containing moist steam-pasteurised growing medium with tops covered with a mesh sheath capable of retaining emerging flies. Microscopic diagnosis of the trapped flies suggested that the morphological characteristics were congruent with those of C. capitata, which was confirmed through cytochrome c oxidase I (COI) gene sequence alignment with a 100% bootstrap value and 99% confidence probability when compared with those from the National Centre for Biotechnology Information database. This study demonstrated that M. zeyheri is a host of C. capitata. Therefore, C. capitata from infestation reservoirs of M. zeyheri fruit trees could be a major threat to the tropical and subtropical fruit industries in South Africa owing to the fruit-bearing nature of the new host. © 2015 Society of Chemical Industry. © 2015 Society of Chemical Industry.

  1. Dosimetry practice for irradiation of the Mediterranean fruit fly Ceratitis capitata (Wied.)

    In a sterile insect technique (SIT) programme the sterility of mass-reared insects, in our case Mediterranean fruit flies, is of primary importance. Mediterranean fruit fly pupae are irradiated in an AECL-CP-JS-7400 irradiator. Originally the capacity was 31,300 Ci, but because of the natural decay of cobalt, the actual source strength is 14,836 Ci. Thus, the dose with which the pupae are irradiated is 14.5 +- 1 krad (145 +- 10 Gy). A great risk in the daily release of sterile flies is that some batches of fertile flies may also be released. To ensure that this does not occur, continuous dosimetric check-ups have to routinely be carried out. Fricke dosimetry is ideal for this purpose because it has a range of response to doses of 4 to 40 krad (40 to 400 Gy) and because it is an economic and simple dosimetric system. (author)

    2007-01-01

    The pattern of gas-exchange (CO 2 emission) was investigated for developing Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann) pupae incubated at different temperatures. This study was undertaken to explore the usefulness of gas-exchange systems in the determination of physiological age in developing pupae that are mass produced for sterile insect technique projects. The rate of CO 2 emission was measured in a closed flow-through system connected to commercial infrared gas analysis equipment. Metabolic activity (rate of CO 2 emission) was related to pupal eye-color, which is the current technique used to determine physiological age. Eye-color was characterized digitally with 3 variables (Hue, Saturation and Intensity), and color separated by discriminant analysis. The rate of CO 2 emission throughout pupal development followed a U-shape, with high levels of emission during pupariation, pupal transformation and final pharate adult stages. Temperature affected the development time of pupae, but not the basic CO 2 emission patterns during development. In all temperatures, rates of CO 2 emission 1 and 2 d before adult emergence were very similar. After mid larval-adult transition (e.g., phanerocephalic pupa), digital eye-color was significantly correlated with CO 2 emission. Results support the suggestion that gas-exchange should be explored further as a system to determine pupal physiological age in mass production of fruit flies. (author) [es

    This work was carried out study the effect of gamma irradiation on the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) content in the whole body homogenate of the mediterranean fruit fly, ceratitis capitata (Wied.) pupae were gamma irradiated with different doses (o, 50, 70, 90 and 110 Gy) at two different pupal ages (2 and 4 days before adult emergence ) to estimate the nucleic acids in pupae and adult males, and females. Experimental results showed that gamma irradiation of pupae reduced RNA content, and this reduction was proportional with the applied dose and more pronounced in the younger pupae. However, DNA content was reduced only when the highest dose was applied to pupae irradiated 2 days before adult emergence (older pupae). Concerning adult insects which were gamma irradiated as pupae, the results revealed, generally, that males and females which were irradiated 2 days before adult emergence were more affected than those irradiated 4 days before adult emergence. The male DNA content and the female RNA content showed high degrees of reduction which, more or less, increased with increasing the dose used. On the other hand, female DNA and male RNA contents were slightly, changed. The significant importance of the results and some statistical interrelations were discussed

    The Mediterranean fruit fly Ceratitis capitata Wied. (Diptera: Tephritidae), has been artificially reared and used for the application of the sterile insect technique and other purposes, throughout the world. The larval diet used is rather expensive and it is mixed in the rearing facility. The most expensive ingredient used in this diet is yeast which is variable in composition and has a relatively short shelf life due mainly to its high nutritional value. This is particularly true for all countries like Greece which do not manufacture brewer's yeast. Also, it is widely known that the Mediterranean fruit fly larvae grow in a wide variety of fruits and artificial diets. These fruits and artificial diets, although very different in chemical/nutritional as well as physical/ecological parameters, are successfully tolerated and utilised by the larvae. These observations prompted the initiation of research into diets containing a variety of low cost ingredients widely used in the vertebrate feed industry and easily found in any country. To our knowledge, no one has tested complete diets produced by well-established feed manufacturers for larval rearing of this insect

    Certain problems caused by the use of insecticides in the management of agricultural pests, such as environmental pollution, insecticide resistance and disturbance of biological balance, has led to the development of selective pest control methods. A prominent place among these for the control of the Mediterranean fruit fly has been attained by the species specific sterile-insect technique (SIT). This study reviews the status of field programmes in countries of the Mediterranean basin, and of related mass rearing, irradiation and field release methodology. The SIT has been successfully tested in Spain, Italy, Israel and Cyprus. In all these cases, however, tests were conducted in small semi-isolated areas where at best a high degree of suppression but not eradication of the fly could be obtained since immigration of gravid females was always possible. The SIT programme in Cyprus and data on medfly ecology in the island is here reviewed in more detail. A proposal is make for the eradication of medfly from Cyprus by the use of an integration of methods, namely bait spraying, cultural practices and sterile-insect releases. (author)

    As an alternative to chemical control or as a part of integrated pest management (IPM program), there is a resurgence of interest in using microbial agents for pest population suppression before the application of the sterile insect technique (SIT) against the Mediterranean fruit fly, Ceratitis capitata (Wiedmann). The insect-fungus interaction between the fungal isolates, Aspergillus niger and Penicillium oxalicum, when applied as a spore suspension against the adults of Medfly in the laboratory showed visual fungal development after 7 days from inoculation. Examination of the infected parts of the dead fly with light microscopy showed a markedly damage as evidenced by the occurrence of the attached conidia and features of pathogen penetration. Using the scanning electron microscopy (SEM), the abundant sporulation of both fungal isolates was investigated over all parts of the dead fly and their associated sensillae. The recognized shape of the fungal conidial spores and their arrangement on the hyphae of both bio agents was investigated. This ultra structural study may be helpful in evaluating the effectiveness of both fungal bio agents on the functions of all infected parts of the insect and their associated sensillae (the main communication system between insects, their internal and external environment) and their main role in the courtship, male mating ability, the selection of fruit host plants necessary for the adults food and also the selection of a suitable oviposition site

    Several studies support the effectiveness of increasing the consumption of fruits and vegetables (F&V) to prevent hypertension. However, none of them have been conducted in a Mediterranean setting. The aim of this study was to assess the association between F&V consumption and the risk of hypertension. A prospective Mediterranean study (the SUN cohort), including 8594 participants aged 20-95 years (mean, 41.1) with median follow-up of 49 months. Analyses according to the joint classification by olive oil and F&V consumption showed a significant inverse relation between F&V consumption and the risk of hypertension only among participants with a low olive oil consumption (oil intake stratum. We found a statistically significant interaction (P=0.01) between olive oil intake and F&V consumption. These data suggest a sub-additive effect of both food items.

    Fruit flies are one of the most important plant pests of the world, in terms of the number of fly species involved, the regions in which they are present, and the variety of hosts they infest. Anastrepha is present in the Americas; Bactrocera in Asia and Ceratitis in Africa; Dacus in Africa and South East Asia, Australia and South Pacific Islands; and Rhagoletis in Chile, Peru, Eastern and Western USA, Europe and Asia (from Sweden to Kyrgystan and from Russia to France). There is an important species of Bactrocera, the Olive Fruit Fly (B.oleae), present in all olive-growing regions of Africa, Europe, the Middle East and Arab countries. Seventy five species of plants of economic importance are infested by fruit flies. Among them are tropical fruits such mango, guava, banana, papaya, fig, passion fruit and avocado; temperate fruits such as citrus (orange, grapefruit, tangerine, etc.), stone fruits (peach, apricot, cherry, etc.), nuts, grape, apple and pear; and vegetable crops such as cucurbits (squash, melon, watermelon), tomato, and eggplant. Fruit flies are present in 178 countries and islands; they are ubiquitous throughout the world between 45 deg. North and 45 deg. South latitude. Twenty species of fruit flies are the most harmful because of the range of hosts they infest and the many countries affected.

    Fruit flies are one of the most important plant pests of the world, in terms of the number of fly species involved, the regions in which they are present, and the variety of hosts they infest. Anastrepha is present in the Americas; Bactrocera in Asia and Ceratitis in Africa; Dacus in Africa and South East Asia, Australia and South Pacific Islands; and Rhagoletis in Chile, Peru, Eastern and Western USA, Europe and Asia (from Sweden to Kyrgystan and from Russia to France). There is an important species of Bactrocera, the Olive Fruit Fly (B.oleae), present in all olive-growing regions of Africa, Europe, the Middle East and Arab countries. Seventy five species of plants of economic importance are infested by fruit flies. Among them are tropical fruits such mango, guava, banana, papaya, fig, passion fruit and avocado; temperate fruits such as citrus (orange, grapefruit, tangerine, etc.), stone fruits (peach, apricot, cherry, etc.), nuts, grape, apple and pear; and vegetable crops such as cucurbits (squash, melon, watermelon), tomato, and eggplant. Fruit flies are present in 178 countries and islands; they are ubiquitous throughout the world between 45 deg. North and 45 deg. South latitude. Twenty species of fruit flies are the most harmful because of the range of hosts they infest and the many countries affected. These 20 are subject to quarantine: trade in fresh produce is restricted to avoid the introduction of any one of these species. The Mediterranean Fruit Fly, or simply Med Fly, (Ceratitis capitata Weid.) is the most harmful of all. It is present in 77 countries and infests 22 hosts of economic importance. From its origin in Central Africa, it has invaded northern Africa, Mediterranean Europe, the Middle East, all the Americas, and Australia.

    The Mediterranean fruit fly (medfly) is the only fruit fly of economic importance affecting a large number of fruits and vegetables in the Maghreb (Algeria, Libyan Arab Jamahiriya, Morocco and Tunisia). The medfly causes losses of fresh fruit and vegetables in this region of about US $90 million each year. Therefore, eradication of this pest at this time would be very beneficial. Technologies are available to eradicate the medfly which will have no significant negative environmental impacts, and they can be used to accomplish eradication at reasonable cost. This report outlines the procedures available to eradicate the medfly from the Magherb with primary reliance on the use of sterile flies. A large fruit fly rearing facility, of modular design, must be constructed in the Mediterranean Basin and outside the Maghreb to produce and sterilize flies. Refs, 2 tabs

    The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is one of the most economically damaging pests in the world and has repeatedly invaded two major agricultural states in the United States, Florida and California, each time requiring costly eradication. The Mediterranean fruit fly gains entry primarily in infested fruit carried by airline passengers and, since Florida and California each receive about 13 million international passengers annually, the risk of Mediterranean fruit fly entering the United States is potentially very high. The risk of passengers bringing the pest into Florida or California from Mediterranean fruit fly-infested countries was determined with two novel models, one estimated seasonal variation in airline passenger number and the other defined the seasonal and spatial variability in Mediterranean fruit fly abundance. These models elucidated relationships among the risk factors for Mediterranean fruit fly introduction, such as amount of passenger traffic, routes traveled, season of travel, abundance of Mediterranean fruit fly in countries where flights departed, and risk of the pest arriving at destination airports. The risk of Mediterranean fruit fly being introduced into Florida was greatest from Colombia, Brazil, Panama, Venezuela, Argentina, and Ecuador during January-August, whereas primarily the risk to California was from Brazil, Panama, Colombia, and Italy in May-August. About three times more Mediterranean fruit flies were intercepted in passenger baggage at airports in Florida than California, although the data were compromised by a lack of systematic sampling and other limitations. Nevertheless, this study achieved the goal of analyzing available data on seasonal passenger flow and Mediterranean fruit fly population levels to determine when surveillance should be intensified at key airports in Florida and California. © The Authors 2016.

    In experiments between April and September 1984, the behaviour of nonirradiated and radiation-sterilized laboratory-adapted adults of the tephritid Ceratitis capitata was observed on apples hung on guava trees in outdoor cages in Hawaii. The numbers of nonirradiated females observed resting on fruit were reduced several times by the presence of irradiated females, either alone or with irradiated males, but not by irradiated males alone. Similarly, the number of nonirradiated females observed ovipositing and the duration of oviposition was reduced by the presence of irradiated females. In control cages (all nonirradiated flies), the duration of oviposition by females averaged 255.9±15.0 s on fruit, while most of nonirradiated and irradiated females in the mixed (treatment) cage averaged 157±19.8 s and 77.5±7.5 s on fruit, resp. Irradiated females behaved skittishly on fruit and frequently engaged in physical encounters with other flies.

    Twelve essential oils from Mediterranean aromatic plants were tested at different doses against four fungi known as causal agents of post-harvest orange fruit rot: Botrytis cinerea, Penicillium italicum, Phytophthora citrophthora, and Rhizopus stolonifer. Essential oils were obtained from Hyssopus officinalis, Lavandula angustifolia, Majorana hortensis, Melissa officinalis, Ocimum basilicum, Origanum vulgare, Salvia officinalis, and Thymus vulgaris (Family Lamiaceae), Verbena officinalis (Family Verbenaceae), and Pimpinella anisum, Foeniculum vulgare, and Carum carvi (Family Apiaceae). Because preliminary in vitro experiments showed that only the oils from V. officinalis, T. vulgaris, and O. vulgare exhibited some fungistatic activity against the above-named fungi, these three essential oils were used in successive in vivo tests carried out to protect healthy "Washington navel" orange fruits from artificial infection by the same micromycetes. The essential oil of T. vulgaris, at a 2,000 ppm dose, controlled fruit rot by B. cinerea, P. citrophthora, and R. stolonifer but was ineffective against P. italicum. Essential oils of V. officinalis and O. vulgare inhibited infection by the first two fungi and only by P. citrophthora, respectively. This finding represents an important result, with the goal of using the essential oils as natural preservatives for food products, due to their positive effect on their safety and shelf life.

    Rice hulls as a new bulking component for the larval rearing of the mediterranean fruit fly, ceratitis capitata wied. Was tested in the laboratory; and 4 formulas of rice hulls and wheat bran were evaluated biologically and financially. When rice hulls and wheat bran were mixed in the ratio of 3:1, all biological aspects and response to gamma radiation (90 Gy) of the produced adults were normal except for male fertility that decreased by about 13% of that of the bran medium (control); while male mating competitiveness was increased. When rice hulls were used without bran, only adult emergece and female fecundity were decreased by about 2% and 20%, respectively as compared to control medium (totally wheat bran); while larval duration increased by one day. The fourth formula consisting of wheat bran and rice hulls in the ratio of 1:1 showed the least favourite bulking component. Calculations showed that one million pupal production costed $26.6,22.2, 20.2 and 21.4 for the bulking ratios (hulls : bran) 0.1, 1:1, 3:1 and 1:0,respectively

    Altogether 27 morphological mutations on the five autosomes of the Mediterranean fruit fly, Ceratitis capitata (Wied.), have been isolated and studied in the author's laboratory during 22 years of research on the genetics of this species. Of the 27 loci, 18 were located on chromosomes 4 and 5. No mutant loci were identified on the sex chromosome in the laboratory. Linkage relations, map distances and linear arrangements on the respective chromosomes were established for most of the 27 mutant traits. The wp and dp traits were utilized in the construction of genetic sexing lines in laboratories involved in studies of the sterile insect technique. The occurrence and consequences of male recombination are discussed. (author)

    The Mediterranean fruit fly (medfly) (Ceratitis capitata) lays eggs in fruits, where larvae subsequently develop, causing large-scale agricultural damage. Within its digestive tract, the fly supports an extended bacterial community that is composed of multiple strains of a variety of enterobacterial species. Most of these bacteria appear to be functionally redundant, with most strains sustaining diazotrophy and/or pectinolysis. At least some of these bacteria were shown to be vertically inherited, but colonization, structural, and metabolic aspects of the community's dynamics have not been investigated. We used fluorescent in situ hybridization, metabolic profiling, plate cultures, and pyrosequencing to show that an initial, egg-borne, diverse community expands throughout the fly's life cycle. While keeping “core” diazotrophic and pectinolytic functions, it also harbors diverse and fluctuating populations that express varied metabolic capabilities. We suggest that the metabolic and compositional plasticity of the fly's microbiota provides potential adaptive advantages to the medfly host and that its acquisition and dynamics are affected by mixed processes that include stochastic effects, host behavior, and molecular barriers.

    The gene nanos (nos) is a maternal-effect gene that plays an important role in posterior patterning and germ cell development in early stage embryos. nos is known from several diverse insect species, but has so far not been described for any Tephritid fruit fly. Here, we report the molecular cloning and expression pattern of the nos orthologous gene, Ccnos, in the Mediterranean fruit fly Ceratitis capitata, which is a destructive pest of high agricultural importance. CcNOS contains 398 amino acids and has a C-terminal region with two conserved CCHC zinc-binding motifs known to be essential for NOS function. Transcripts of Ccnos were confirmed by in situ hybridization to be maternally-derived and localized to the posterior pole of early stage embryos. Regulatory regions of nos have been employed in genetic engineering in some dipterans such as Drosophila and mosquitoes. Given the similarity in spatial and temporal expression between Ccnos and nos orthologs from other dipterans, its regulatory regions will be valuable to generate additional genetic tools that can be applied for engineering purposes to improve the fight against this devastating pest.

    The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), was discovered in southern Mexico sometime in 1977 near Tapachula, Mexico. Farmers in Texas and other states of the United States became concerned that the Mediterranean fruit fly would spread northward through Mexico and into the US. In response to this threat to US agriculture, funds were appropriated by Congress to be used by the US Department of Agriculture (USDA) - Animal and Plant Health Inspection Service (APHIS) to eradicate the Mediterranean fruit flies from Mexico and establish a barrier zone in Guatemala to keep the Mediterranean fruit flies from spreading northward into Mexico. In Mexico and Guatemala, the organisation called MOSCAMED was created to support the programme. Aerially applied malathion bait sprays were used in the suppression programme beginning in Mexico in 1982 and beginning in Guatemala in 1985. Mexico has been free of the Mediterranean fruit fly since 1982, except for outbreaks in the southernmost state of Chiapas, adjacent to Guatemala. The spraying of malathion was banned by the government of Guatemala in early 1996 because of concern regarding possible adverse effects on honey bees. By this time, research had been started to evaluate the use of xanthene dyes as a potential alternative to malathion in protein bait sprays for the suppression of the Mediterranean fruit fly (Liquido et al. 1995). Light-activated toxicity of xanthene dyes has been documented for more than two dozen insect species overall (Heitz 1997). Field trials of xanthene dyes, as a safer alternative to malathion in bait sprays targeting the Mediterranean fruit fly, were begun in Hawaii in 1994 and in Guatemala in 1996 and proved to be promising. By the end of 1996, xanthene dyes were registered as a substitute for malathion to suppress/eradicate Mediterranean fruit flies in the barrier zone. In January, 1997, MOSCAMED-Guatemala began a spray programme with xanthene dyes as the toxicant in a protein bait

    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 The sublethal effect of extracts of Azadirachta indica on Ceratitis capitata was evaluated. Two pairs of flies were treated in plastic tubes with cotton placed in plastic cages. An artificial diet (hydrolyzed protein + sugar was provided ad libitum. The extracts affected significantly the longevity of C. capitata. The pre-oviposition period were not significantly affected by the extracts. The A. indica branches extracted with dichloromethane (888 ppm affected significantly the fecundity and fertility, reducing the number of eggs laid to approximately 80 % and the egg hatching by 30 % at the 8th day. Therefore, the neem branches extracted with dichloromethane affected the reproduction of C. capitata.

    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

  6. 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)

    A mass-rearing facility for Mediterranean fruit fly Ceratitis capitata (Wiedemann) was commissioned in Stellenbosch in 1999 to produce sterile male fruit flies for a sterile insect technique (SIT) project in commercial fruit orchards and vineyards in the Western Cape province of South Africa. The mass-rearing procedure was largely based on systems developed by the FAO/IAEA Agriculture and Biotechnology Laboratory, Seibersdorf, Austria. A number of genetic sexing strains were used to produce only males for release. Initial cramped rearing and quality management conditions were alleviated in 2001 with the construction of a new adult rearing room and quality control laboratory. In 2002 a comprehensive Quality Management System was implemented, and in 2003 an improved genetic sexing strain, VIENNA 8, was supplied by the FAO/IAEA Laboratory in Seibersdorf. For most of the first 3 years the facility was unable to supply the required number of sterile male Mediterranean fruit flies for the SIT program without importing sterile male pupae from another facility. From mid-2002, after the quality management system was implemented, both production and quality improved but remained below optimum. After the introduction of the VIENNA 8 genetic sexing strain, and together with an improvement in the climate control equipment, production stability, and quality assurance parameters improved substantially. The critical factors influencing production and quality were an inadequate rearing infrastructure, problems with the quality of the larval diet, and the initial absence of a quality management system. The results highlight the importance of effective quality management, the value of a stable and productive genetic sexing strain, and the necessity for a sound funding base for the mass-rearing facility.

    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

    Research is continuing towards the ultimate goal of developing an efficient system of separating the sexes of the Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann). The authors are evaluating existing pupal colour sexing strains, as well as the potential of genetic engineering in creating a strain with useful genetic sexing properties. Collaborative research is under way between the United States Department of Agriculture/Agricultural Research Service (Honolulu) and the University of Hawaii (D. Haymer) regarding molecular approaches to the problem. Two pupal colour sexing strains are being compared: one of pure European stock and one backcross Hawaiian strain derived from the former. Results are presented for laboratory viability and quality parameters between the two strains, and further comparisons are made for behaviour in the field, including mating cage and free release assays. To date, the results indicate that the Hawaiianized strain is very competitive with normal (non-translocated) strains, while the pure foreign strain performs at a substandard level in Hawaii. After three years and over 25,000 embryos injected, there is still no evidence for genomic transformation of the medfly using Drosophila p elements. On the basis of positive evidence from a recently developed assay with the oriental fruit fly, Dacus dorsalis, microinjections with this species have been initiated. In the medfly, however, there is evidence for both apparent cytoplasmic inheritance of the neomycin resistance gene and bona fide transient expression of this gene. Currently being investigated are an alternative potential gene transfer system, concatemerized linear DNA of the neomycin structural gene, and metallothionein gene resistance as an alternative to neomycin resistance. Long range research has also been initiated to search for potential transposable vectors present in tephritids themselves. (author). 9 refs, 4 tabs

    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

    The locus of the alcohol dehydrogenase (ADH) has been used to develop a genetic sexing mechanism in the Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann). Previous work (1982-1984) has led to the isolation of a translocation linking a null mutant of this locus to the Y chromosome of the males. This strain, T-128, together with others showing different ADH electrophoretic patterns, have been assayed for their resistance to alcohols, such as allyl-alcohol, pentynol, ethanol and 2-propanol. The strains carrying the T-128 translocation show a differential, sex dependent survival to some of these alcohols. Part of this work is still in progress. The mutagenic ethyl methanesulphate (EMS) is being used to induce new ADH null mutants using the strain T-128 as a marker. Several hundred females have been treated with 0.04% EMS and then outcrossed to T-128 males. Their progeny is put through selective larval medium (0.08% allyl-alcohol) and the surviving F 1 individuals and subsequent F 2 are being analysed. Population studies have shown that the genetic sexing strain, T-128, is a double translocation with complete linkage between the Adh N allele (chromosome 2), and the Y chromosome, and incomplete linkage of the Y with the wild type allele of the apricot eye locus (ap + ) of chromosome 4.

    The Mediterranean fruit fly (Medfly) is one of the world's most economically damaging pests. It displays highly seasonal population dynamics, and the environmental conditions suitable for its abundance are not constant throughout the year in most places. An extensive literature search was performed to obtain the most comprehensive data on the historical and contemporary spatio-temporal occurrence of the pest globally. The database constructed contained 2328 unique geo-located entries on Medfly detection sites from 43 countries and nearly 500 unique localities, as well as information on hosts, life stages and capture method. Of these, 125 localities had information on the month when Medfly was recorded and these data were complemented by additional material found in comprehensive databases available online. Records from 1980 until present were used for medfly environmental niche modeling. Maximum Entropy Algorithm (MaxEnt) and a set of seasonally varying environmental covariates were used to predict the fundamental niche of the Medfly on a global scale. Three seasonal maps were also produced: January-April, May- August and September-December. Models performed significantly better than random achieving high accuracy scores, indicating a good discrimination of suitable versus unsuitable areas for the presence of the species. (author)

    The beneficial impact of the traditional Mediterranean diet pattern on adiposity is still under debate, and this has never been assessed in a developing Mediterranean country. To assess the relationships between adherence to a traditional Mediterranean diet and adiposity indexes, that is, body mass index (BMI) and waist circumference (WC), in a sample from rural Lebanon. A sample of 798 adults, aged 40-60 years, was selected in continental rural areas of Lebanon for a cross-sectional study. The questionnaire included socio-demographic, anthropometric and dietary sections. The daily consumption frequencies of selected food groups, categorized as positive or negative components, were calculated based on a food frequency questionnaire. Adherence to the Mediterranean diet was assessed using six a priori scores; including the widely used Mediterranean diet score (MDS). Associations between diet scores and BMI and WC were assessed. Overall, the diet of the study sample only partially matched the traditional Mediterranean diet. A total of 17.0% of men and 33.7% women were obese. The MDS was negatively associated (Pwomen. The constructed composite Mediterranean score combining positive components of the diet (whole cereals, vegetables, legumes and fruit, olive oil and fish) and negative components adapted to this sample (refined cereals and pastries, and liquid sweets) was consistently and negatively associated with both BMI and WC for men and women in multivariate models. A 2-point increase in that score was associated with a decrease in BMI of 0.51 and 0.78 kg m(-2) and a decrease in WC of 2.77 and 4.76 cm in men and women, respectively. The results demonstrate that a Mediterranean diet is negatively associated with obesity and visceral adiposity in a rural population of a developing Mediterranean country.

    The petroleum ether extract of the plant Nicandra Physaloide L. and the alcoholic plant extract of Dodonaea viscosa L. were subjected to the biological evaluation to assess their toxic effects on the reproductive abilities and survival survival of the Mediterranean fruit fly Ceratitis Capitata Wied., exposed to the treated diet in the larval stage. The produced full grown pupae (1-2 day old) were gamma irradiated (90 Gy). Neither percent pupation, adult emergence nor survival were affected by treating larvae with any of the two plant extracts alone at the tested concentrations (0, 0.5, 1, 3,5 and 7 ppm).Applying each of the two plant extracts recorded insignificant effect on egg hatch. however, irradiating pupae produced from larvae subjected to the extracts significantly affected the male fertility and mating competitiveness

    Larval artificial diet of the mediterranean fruit fly, ceratitis capitata (wied.) was treated with the Lc50 of the juvenile hormone, pyriproxyfen. The produced full grown pupae were gamma irradiated at doses of 50, 70, 90 and 110 Gy. The produced four days-old adults were dissected for removing the testis or the ovary for microscopical investigations. The study revealed that pyriproxyfen and/or irradiation affected insignificantly the volume of the male testis and significantly the ovary of the female, injured the process of spermatogenesis and caused gross damage to the female ovary. The damage was increased with increasing the gamma dose level. Deformations were observed including shrinkage of testis and ovary contents, vacuolations and disturbances in the process of sperm and oocyte maturation

    The present investigation aims at producing sterile adult Mediterranean fruit fly, Ceratitis capitata Wied. Having the best possible vitality through the use of irradiation and /or a mutagenic substances to be used in a sterile insect technique program. Several types of mutagenic that were thought to cause mutations were used as IGR's, temperature, formaldehyde, colchicine, alcohols, serve ral types of larval rearing media and gamma-rays. In a common pathway, malic enzyme (ME) activity, adenosine triphosphatase (ATPase) enzyme activity and the total protein contents are studied as direct parameters for measuring vitality of the insect. It was found that there is an increment at levels of these parameters due to the treatment of egg stage by the previously mentioned treatments specially the usage of the rice hulls as a bulking component in the larval rearing media alone or followed by irradiation of the pupal stage with 90 Gy

    Dark spontaneous mutant pupae were isolated from brown laboratory reared pupae of the Mediterranean Fruit Fly, Ceratitis Capitata (Wied). This mutant was used construct a genetic sexing strain (G.S.S.) based on pupal sorting. Obtained data showed that there were no clear biological differences between the brown pupa wild-type) and dark pupae (mutant). Fecundity, %pupation, pupal size, pupal weight, % adults emergence, sex ratio, male mating competitiveness and male insemination females mated with studied. However, the present hatch ability of eggs laid by normal females mated with normal males emerging from the dark pupae was significantly reduced, compared to that of the brown pupae. No significant differences regarding the effects of gamma radiation (90 Gy) on all biological aspects were observed in both strains

    A programme to develop genetic sexing mechanisms in the Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann), was initiated at the IAEA Laboratories, Seibersdorf, in 1983. Because of the potential benefits arising from the elimination of females early in the developmental cycle, combined with the anticipated relative ease of inducing temperature sensitive lethal (tsl) factors, it was decided to attempt to induce and isolate tsl factors active in the egg or early larval stages. Initially, five recombination suppressor (RS) strains were isolated. The degree of recombination suppression ranged from 77.6% to 99.1%. The viability of each of the five RS strains was assessed and RS 30/55 was selected as the most suitable strain. Ethyl methanesulphonate (EMS) was used to induce the tsl factors, by feeding two-day old adult males with a suspension of EMS in a 10% solution of sugar in the drinking water supply. Temperature tolerance tests indicated a discriminating temperature of 32 deg. C when isolating tsl factors active in the egg stage and 35 deg. C when isolating such factors in the early larval stage. A total of 39 and 22 tsl factors have been isolated in the two stages, respectively. However, none has yet proved stable. Induction of tsl factors with a reduced dose of EMS is now being attempted. An alternative genetic sexing programme was initiated in 1985, based on the use of pupal colour dimorphisms. Previously, a genetic sexing strain, T:Y(wp + )101, based on a white female/brown male puparial colour dimorphism, had twice been assessed for stability under mass rearing conditions. In both cases the sexual colour dimorphism disintegrated immediately. Another similarly dimorphic strain, T:Y(wp + )30C, was developed. This strain remained stable for seven generations of mass rearing, after which it started to disintegrate. Disintegration of this strain was probably caused by accidental contamination by wild type medflies. 34 refs, 1 fig., 1 tab

    The mediterranean fruit fly, (Medfly), Ceratitis capitata (Wiedemann) (Diptera : Tehritidae), is one of the most important agricultural pests. It is considered (Hagen et al, 1981) to have originated from tropical Africa, from where it spread to north and south africa, invaded spain and subsequently spread into the european mediterranean countries and the middle east. It appeared in hawaii, costa rica, south america, spread north through central america and finally into southern mexico. There are (kourti et al, 1990), 235 fruit trees, nut trees and vegetables recorded as medfly hosts . Of the 253 hosts, 40 are considered h eavily or generally infested . The importance of controlling this injurious pest needs no emphasis. Different methods of control had been applied against this pest, all of them are directed towards the protection of fruits from infestation. Although man used chemical compounds which played and are still playing an important role in this struggle against insects, the extensive and continued use of broad - toxicity spectrum and long lived pesticides created a number of problems, among which environmental pollution represents one of the grave concerns. Moreover, the appearance of resistance in several species of insects to the action of these chemical is another problem

    In the present work, survival of the Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) on artificially infested 'Clemenules' clementine mandarins (Citrus reticulata Blanco) was assessed on fruit subjected to integrated quarantine treatments consisting of irradiation with X-rays at doses of 0 (control), 30, 54, and 164 Gy followed by exposure to 1 deg C for 0 (control), 3, 6, 9, or 12 days. Additionally, physico-chemical (rind color, firmness, and physiological disorders, soluble solids concentration, titratable acidity, maturity index, juice yield, and ethanol and acetaldehyde content) and sensory (sweetness, acidity, sensory maturity index, off-flavors, and mandarin-like flavor) fruit quality of 'Clemenules' clementines were assessed on X-irradiated fruit exposed to 1 deg C for 0 (control), 6, or 12 days. Complete insect mortality with no negative effects on fruit quality after 7 days at 20 deg C of shelf life was obtained on clementines firstly X-irradiated at 30 Gy and subsequently exposed to 1 deg C for 2 days. This combination of treatments considerably reduced quarantine time if compared to standard cold quarantine treatments (1.1-2.2 deg C for 14-18 days) and therefore showed promise as a potential commercial treatment for Spanish citrus exports [es

    The Mediterranean fruit fly (Medfly), Ceratitis capitata (Wied.), is arguably the world's most widespread pest of fresh fruit production. With mounting controversy over using chemicals against insect pests, the sterile insect technique (SIT) has become increasingly more important as a successful technology in controlling or eradicating many insect pests. However, the wider adoption of SIT for Medflies has been hindered by damage to fruit from sterile female stings (Hendrichs et al. 1995). Moreover, the release of sterile females in SIT for Medflies is not efficacious (Hendrichs et al. 1995), a point validated in the field in Hawaii (McInnis et al. 1994) and Guatemala (Rendon, personal communication). Hendrichs et al. (1995) list many other advantages for releasing only male Medflies including improved economy, increased safety and improved field monitoring. Genetic systems for the separation of sexes have been developed for Medflies (Franz and Kerremans 1994, Willhoeft et al. 1996) and they allow for large-scale releases of only males. Genetic sexing strains (GSS), as they are known, are based upon selectable characters linked to the male sex by using a Y-autosome translocation (Franz et al. 1996). There are two types of GSS used in mass rearing. First, strains based upon a recessive mutation (wp) change the pupal colour from brown to white. In these strains, females emerge from white pupae and males from brown pupae. A machine is used to sort the pupae based upon colour. First described by Robinson and Van Heemert (1982), the most recent strain, SEIB 6-96 based upon the T(Y;5) 2-22 translocation, is relatively stable in small scale rearing (Franz et al. 1994). Second are the temperature sensitive lethal strains (wp/tsl) which carry a temperature sensitive lethal (tsl) mutation in addition to wp. In tsl strains, female embryos are killed by exposing eggs to a 3 C temperature during development (Franz et al. 1996). Male embryos are not temperature sensitive and

    Twenty-eight functional loci and four morphological gene markers have been assigned to five of the six linkage groups of the Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann). The linkage group labelling system, proposed by Saul and Roessler, has been adopted. Map distances, obtained for twenty markers, showed the marked loci to be distributed over wide map intervals in all five autosomal linkage groups. The available information appears adequate for determining the position of chromosomal characteristics peculiar to each chromosome. (author). 14 refs, 2 tabs

The release area was surrounded by a 500-m-wide low-volume (LV) bait spray barrier. Sterile flies were released from the ground and by air twice weekly. Results indicate successful control of the wild fly population for several months only and a clear suppression until July; thereafter, wild fertile females immigrated into the release area through the LV barrier.

    A biological comparison between two t sl s trains of the Mediterranean fruit fly, Ceratitis capitata Wied., was done. The biological parameters of this comparison involved pupal production, pupal emergence, adult sex ratio and flying ability. Two kinds of larval media were used (bran or carrot powder). Survival of the produced flies was also determined when deprived from water and food. Larval rearing was done in 5 kg trays (usual mass rearing) on sugar and bran medium or in experimental Petri dishes (15 cm in diameter and 1 cm in height) on powdered carrot medium. The results obtained revealed a better performance of Vienna 8 strain (V-8) than Vienna 7 strain (V-7) when larval rearing was carried out in 5 kg trays on the usual bran medium. However, when carrot larval diet was offered in small Petri dishes, V-7 was better as compared to V-8 strain. Adult males or females produced by V-7 showed longer survival than those produced by V-8 when adults were kept without food or water

    Data concerning spatial and/or temporal variation among 29 samples of four populations of the Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann) were obtained by computation of gene frequency values at 25 biochemical loci. The four populations came from Africa (Kenya and Reunion) and from the Mediterranean basin (Sardinia and Procida Island). Statistical parameters of genetic variation included average heterozygosity per locus, proportion of polymorphic loci and average number of alleles per locus. The data were analysed using Principal Component Analysis and Wright's fixation index. Significant differences in genetic heterogeneity were observed on a regional scale in relation to the dispersion of the fly from its supposed area of origin (East Africa) towards the periphery (Mediterranean region). The samples from Procida, collected at different seasons for four consecutive years (1983-1986), provided consistent indications of temporal changes in the genetic structure of this population, and permitted evaluation of the efficiency of a sterilized male strain (T-101) released during a sterile insect technique programme on Procida in 1986.

    The sterile insect technique (SIT) is a method of biological control whereby millions of factory reared sterile male insects are released into the field. This technique is commonly used to combat the Mediterranean fruit fly (Ceratitis capitata, Diptera: Tephritidae). Sterile medfly males are less competent in attracting and mating with wild females, a property commonly linked to the irradiation process responsible for the sterilization. As bacteria are important partners in the fly's life cycle, we used molecular analytical methods to study the community structure of the gut microbiota in irradiated male medflies. We find that the sterilizing irradiation procedure affects the gut bacterial community structure of the Mediterranean fruit fly. Although the Enterobacteriaceae family remains the dominant bacterial group present in the gut, the levels of Klebsiella species decreases significantly in the days after sterilization. In addition, we detected substantial differences in some bacterial species between the mass rearing strain Vienna 8 and the wild strain. Most notable among these are the increased levels of the potentially pathogenic species Pseudomonas in the industrial strain. Testing the hypothesis that regenerating the original microbiota community could result in enhanced competitiveness of the sterile flies, we found that the addition of the bacterial species Klebsiella oxytoca to the postirradiation diet enables colonization of these bacteria in the gut while resulting in decreased levels of the Pseudomonas sp. Feeding on diets containing bacteria significantly improved sterile male performance in copulatory tests. Further studies will determine the feasibility of bacterial amelioration in SIT operations.

    The population suppression success of Mediterranean fruit fly, Ceratitis capitata (Wied.) using sterile insect technique (SIT) depends mainly upon: the release of male only, ability of sterilized males to compete with wild males in mating with wild females and discrimination of released male flies from the wild population. The effect of gamma irradiation doses on the male sterility was evaluated, to determine the level of induced sterility for achieving the balance between sterility and mating competitiveness. For optimal sterilizing dose, 8 different doses of gamma irradiation were tested. The results revealed that the doses 80, 90 and 100 Gy were the effective doses for SIT. In a field cage experiment, the mating ability, mating competitiveness and sexual compatibility were determined for the three effective sterilizing doses. The indices of sexual isolation (ISI) and the relative sterile index (RSI) indicated that mating efficiency of the dose 80 Gy was better than the doses 90 and 100 Gy. Obtained results also revealed that the competitiveness of 80 Gy irradiated males was higher than either 90 or 100 Gy irradiated males. Mutant strains, i.e. white eye white pupae strain (WeWp strain), male linked translocated strain (T strain), temperature sensitive lethal strain (tsl strain) and sergeant 2 strain (Sr 2 strain) were reared and maintained for the construction of genetic sexing strain Vienna 8- Sr 2 strain (GSS V8-Sr 2 ). The results of biological characters of GSSs revealed that, the 3 sexing strains (T, Sr 2 and V8 strains) which have Y- auto some translocation were less productive than the bisexual strain (BSS). Also, the development of tsl and GSS V 8-Sr 2 strains was delayed compared with the BSS strain. The stability of GSS V8-Sr 2 strain in the filter rearing was higher than in the mass rearing throughout 12 successive generations.

    The dispersion of artificially-reared and gamma-sterilized males of the fruit fly Ceratitis capitata was studied in a citrus orchard. About 10,000 adults were tagged through a 32 P artificial medium and released into two different place of the orchard, one place had ripe fruits and the other place without ripe fruits. Flies trapped were collected daily during the first 8 days and then three more surveys once a week. Radioactive flies were detected by liquid scintillator through Cerenkov effect. The data suggested that the number of male trapped was affected by the presence of ripe fruit and by period between release and trapping. The climate factors during the period of the experiment, did not affect the flight distance neither the trapping data. (author)

    Purpose to review the recent relevant evidence of the effects of the Mediterranean diet and lifestyle on health (2015 and first months of 2016). Recent findings Large observational prospective epidemiological studies with adequate control of confounding and two large randomized trials support the benefits of the Mediterranean dietary pattern to increase life expectancy, reduce the risk of major chronic disease, and improve quality of life and well-being. Recently, 19 new reports from large prospective studies showed –with nearly perfect consistency– strong benefits of the Mediterranean diet to reduce the risk of myocardial infarction, stroke, total mortality, heart failure and disability. Interestingly, two large and well-conducted cohorts reported significant cardiovascular benefits after using repeated measurements of diet during a long follow-up period. Besides, PREDIMED, the largest randomized trial with Mediterranean diet, recently reported benefits of this dietary pattern to prevent cognitive decline and breast cancer. Summary In the era of evidence-based medicine, the Mediterranean diet represents the gold standard in preventive medicine, probably due to the harmonic combination of many elements with antioxidant and antiinflammatory properties, which overwhelm any single nutrient or food item. The whole seems more important than the sum of its parts. PMID:27552476

    Comparative studies on pyriproxyfen and fenoxycarb as juvenile hormones applied separately or combined with gamma radiation were carried out for controlling ceratitis capitata. Lc 50's of the two juvenile hormones, pyriproxfen and fenoxycarb, were determined against ceratitis capitata in treated diet by continuous contact of eggs and larvae using various concentrations. The Lc 50 were 32 and 140 ppm for pyriproxyfen and fenoxycarb, respectively. The resulting pupae were gamma irradiated with 90 Gy. Larval and pupal durations were insignificantly affected, pupation and adult emergence were significantly affected while adult survival was insignificantly affected when applying the two JH's. Applying pyriproxyfen alone insignificantly increased egg hatch at the concentrations used (12.5 and 25 ppm) while when fenoxycarb was applied alone egg hatch was significantly decreased at the concentration used (100 ppm). Applying both juvenile hormones each combined with gamma radiation significantly reduced egg hatch. Male mating competitiveness was significantly increased when applying pyriproxyfen at the concentration 25 Ppm. Results indicated that pyriproxyfen was more effective than fenoxycarb against the mediterranean fruit fly ceratitis capitata.1 figs., 3 tabs

    The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is a major pest of fruit crops in the Mediterranean Basin countries. If no control measures are applied in Israel, Palestinian Territories, and Jordan against this pest, the annual fruit losses are estimated to be about U.S. $365 million, which is more than half the total revenue produced by fruits considered to be Mediterranean fruit fly hosts in these countries. Under the current control programs, the direct damage (yield loss and control costs) and indirect damage (environmental impact and market loss) amount to U.S. $192 million per year. This amount could increase each year if the current control programs are kept. The aim of this study was to evaluate, on a regional basis, the economic returns of 3 improved alternative Mediterranean fruit fly control methods using a 9-yr time frame. The control alternatives include population suppression using bait sprays, population suppression using massive release of sterile male flies, and population eradication also using massive releases of sterile male flies. For each option, an action plan was prepared which includes intensity, frequency and timing of sampling (trapping and fruit gathering), control (bait sprays and sterile male releases), and postcontrol (quarantine and emergency capacity) techniques. For the economic evaluation costs and benefits at net present value are computed for each control option to estimate the economic indices. Results indicate that the 3 area-wide control options are technically and economically feasible and all are better than the current control programs. For each option, the economic returns on a medium and long term are discussed, along with the environmental impact. Over the 9-yr time frame, the greatest economic return is from the sterile male suppression option. Over a much longer time frame, the greatest return is for the sterile male eradication option

    Researches have suggested Mediterranean diet might lower the risk of chronic diseases, but data on skeletal muscle mass (SMM) are limited. This community-based cross-sectional study examined the association between the alternate Mediterranean diet score (aMDS) and SMM in 2230 females and 1059 males aged 40-75 years in Guangzhou, China. General information and habitual dietary information were assessed in face-to-face interviews conducted during 2008-2010 and 3 years later. The aMDS was calculated by summing the dichotomous points for the items of higher intakes of whole grain, vegetables, fruits, legumes, nuts, fish and ratio of MUFA:SFA, lower red meat and moderate ethanol consumption. The SMM of the whole body, limbs, arms and legs were measured using dual-energy X-ray absorptiometry during 2011-2013. After adjusting for potential covariates, higher aMDS was positively associated with skeletal muscle mass index (SMI, SMM/height2, kg/m2) at all of the studied sites in males (all P trend0·05). Age-stratified analyses showed that the favourable associations tended to be more pronounced in the younger subjects aged less than the medians of 59·2 and 62·2 years in females and males (P interaction>0·10). In conclusion, the aMDS shows protective associations with SMM in Chinese adults, particularly in male and younger subjects.

    The Mediterranean diet is a healthy dietary pattern known to actively modulate the cell membrane properties. Phase angle (PhA) is a direct measure by Bioelectrical Impedance Analysis (BIA) used as marker of cell membrane integrity. Both food behaviour and PhA are influenced by age, sex and body weight. The aim of this study was to cross-sectionally evaluate the association between the adherence to Mediterranean diet and PhA in 1013 healthy adult patients stratified according to sex, age, and body mass index (BMI). The adherence to the Mediterranean diet was evaluated using the PREvención con DIeta MEDiterránea (PREDIMED) questionnaire. PhA was calculated by BIA phase-sensitive system (50 kHz BIA 101 RJL, Akern Bioresearch, Florence, Italy Akern). In both sexes, at ROC analysis a PREDIMED score ≥ 6 predicted a PhA beyond the median value. At the multivariate analysis, among PREDIMED score, age, and BMI, the PREDIMED score was the major determinant of PhA, explaining 44.5% and 47.3% of PhA variability, in males and females respectively ( p Mediterranean diet and PhA, independently of sex, age, and body weight. This association uncovered a new potential benefit of the Mediterranean diet on health outcomes, as in both sexes higher adherence to the Mediterranean diet was associated to larger PhAs, as expression of cell membrane integrity.

    Full Text Available Background: Dietary pattern is an effective way of studying the effect of diet on diseases. We investigated the association between dietary patterns and blood pressure (BP in adults aged 20-50 years. Methods: In a cross-sectional design, 418 individuals were selected through stratified multistage random sampling from households living in different regions of Shiraz. Information on demographic characteristics, anthropometric features, dietary intakes, and systolic (SBP and diastolic (DBP blood pressure was gathered. Dietary patterns were determined using a validated food frequency questionnaire. Results: Three dietary patterns were specified: vegetable (high in vegetables and legumes, Western-like (high in meat, sugarsweetened beverages, salty and sweet snacks, refined grains, high-fat dairy, and Mediterranean-like (rich in low-fat dairy, fruit, vegetables, nuts, olive, fish, and low in hydrogenated fats. After adjustment for confounders, Mediterranean-like dietary pattern had an inverse association with SBP (β=-0.24; 95% CI: -5.25, -1.27 and DBP (β=-0.17; 95% CI: -3.65, -0.20 in males but not females. Vegetable and Western-like dietary patterns were not associated with BP in either sex after adjusting for confounders. Positive relationships were observed between BP and body mass index (r=0.28 and 0.33 for SBP and DBP, P<0.001, waist circumference (r=0.51 and 0.45 for SBP and DBP, P<0.001, and waist-to-hip ratio (r=0.54 and 0.44 for SBP and DBP, P<0.001. Dietary energy and carbohydrates were positively and fats inversely associated with BP. Among micronutrients, vitamin E had a significant inverse association with BP. Conclusion: Mediterranean-like dietary pattern may lower the risk of hypertension in Shiraz males.

    The present status in genetic sexing for the Mediterranean fruit fly is discussed. This includes the selection of the appropriate sexing gene (which determines the feasibility and practical applicability of the sexing system) as well as the selection of the appropriate Y-autosome translocation (which determines the stability of the sexing system). A temperature sensitive lethal mutation is used to eliminate females during the egg stage. This mutation in combination with new Y-autosome translocations allowed the construction of a genetic sexing strain, named VIENNA-42, that is stable enough for large scale mass rearing. Also described are the analysis of this strain under field cage and field conditions and, in preparation for large scale tests in Guatemala, the outcrossing of VIENNA-42 with genetic material from the target area.

    The present study searches for the improvement vitality of the Mediterranean fruit fly, Ceratitis capitata Wied. Through the induction of a specific variance (mutation) in the genetic material. Several types of treatments that were thought to cause this mutation were used, as IGR's, temperature, formaldehyde, colchicine, alcohols, several types of larval rearing media and gamma-rays. Generally, the activities of the energy enzymes alpha-glycerophosphate dehydrogenase (alpha-GPDH) enzyme lactate dehydrogenase (LDH) enzyme and malate dehydrogenase (MDH) enzyme, when used as a direct measure for the fly vitality, increased due to treatments of the egg stage by the previously mentioned treatments specially by the usage of rice hulls in the larval rearing medium alone or followed by irradiation of the pupal stage with 90 Gy

    The development of stable genetic sexing strains in the Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann), is hampered by the presence of low levels of male recombination. Such recombination may be reduced by minimizing the distance between the translocation breakpoint and the translocated 'sexing' allele. Cytogenetic analysis of mitotic/meiotic and polytene chromosomes could provide information on the selection of such potentially stable genetic sexing strains. Translocation breakpoints in two genetic sexing strains in the medfly, based on a white female/brown male pupal colour dimorphism, have been determined. Preliminary results are described and the advantages and limitations of polytene chromosome analysis for the isolation of stable genetic sexing strains of the medfly are discussed. (author). 31 refs

    Some biological studies of the Mediterranean fruit fly Ceratitis capitata (Wiedemann) were carried out to help in controlling this pest. Three laboratory experiments were done to study the effect of acetone, diethyl ether and ethyl alcohol separately or combined with gamma radiation through egg treatment or larval diet treatment. The gamma dose (90 Gy) was applied only on the produced pupae after egg or larval diet treatment. Concentrations of 0, 25, 50 and 100% of each chemical were applied for treating eggs to evaluate egg hatch, pupation, adult emergence and sex ratio. larval diet treatment was done by adding 20 ml of each chemical concentration to 500 gm of larval diet.Treating eggs with ethyl alcohol separately increased pupation significantly at all concentration used while adult emergence was insignificantly increased with the lowest concentration only (25%). Treating larval diet with ethyl alcohol alone increased pupation insignificantly and adult emergence was insignificantly decreased at different concentrations. Moreover, treating eggs or larval diet with diethyl ether alone significantly increased sex ratio at 50% and 2% concentration, respectively,while differed insignificantly by applying different chemicals either on eggs or on larval diet. Treating eggs with the three chemicals before gamma irradiation of the produced pupae fluctuated egg hatch insignificantly compared to gamma irradiation alone. By applying diethyl ether on eggs or acetone in the larval diet decreased egg hatch insignificantly. Competitiveness values were insignificantly increased by applying ethyl alcohol on eggs, acetone or ethyl alcohol on eggs, acetone or ethyl alcohol in larval diet before gamma irradiation of the produced pupae. Survivals of the produced adults, treated as eggs or in the larval diet with different chemicals and irradiated as pupae, fluctuated insignificantly

    A trial on the construction, maintenance and adaptation of the genetic sexing strain Vienna-8/Sr2 of the Mediterranean fruit fly, Ceratitis capitata (Wied.), has been done in the fruit fly laboratories of the Egyptian Atomic Energy Authority (EAEA) in the cooperation with the laboratories of International Atomic Energy Agency, Vienna. This trial was successful and this strain was maintained in the medfly laboratories of the EAEA for more than 10 generations up till now. Vienna-8/ Sr 2 is very stable strain and carries the dominant mutation called sergeant-2 (Sr 2 ) and could be used as a visible marker for the sterile male flies released in the field for controlling the Mediterranean fruit fly. This visible marker simplifies the discrimination between released sterile males and wild males caught in field monitoring traps. Males of this strain have three white stripes on the abdomen while wild males have only two stripes. The use of this genetic marker, as a replacement of the external dye marker, clearly has an immediate positive impact on the efficiency of Mediterranean fruit fly SIT programs (by using gamma radiation)

    The islands of Madeira are located 980 km west-southwest from mainland Portugal and have a population of approximately 255,000. The islands are volcanic with very little level land suitable for large agricultural production. Approximately 47% of the land area is above 700 m. Thus the area likely to require Medfly control is about half of the islands. Agricultural production is on small scale, frequently part-time and mostly terraced because of the volcanic nature of the land. Grapes for wine and bananas are the predominant fruit crops. Neither are primary Medfly hosts. Citrus and tropical fruits are not produced in large quantities and are generally not of high quality. This is, to a large extent, because intensive Mediterranean fruit fly (Medfly), Ceratitis capitata (Wied.), attack has prevented the establishment of citrus and tropical fruit production. Medflies are present the year round on land below 300 m, resulting in the necessity of continuous control measures, usually insecticide bait sprays. Current annual losses from the Medflies in Madeira are estimated at US$3 million. In 1992, the agricultural officials of Madeira applied for an European Union (EU) grant to eliminate the Medfly from Madeira using the sterile insect technique (SIT). After extensive discussions, the project was changed from eradication to control and approved in late 1993 with EU support of about 8 million ECU over a 7-year period. Subsequently, the Madeira officials applied for, and received, a technical assistance project from the International Atomic Energy Agency (IAEA). The IAEA support is primarily for training and consultant services. Sterile female Medflies puncture fruits when they try to lay eggs. These punctures, called 'sterile stings', result in a reduced crop value. For this reason, the Madeira-Med programme will use only sterile male Medflies in its SIT programme. This not only eliminates the sterile sting problem but also increases the efficacy of the sterile males from

    Wheat bran and molasses were used in larval medium of the Mediterranean fruit fly, Ceratitis capitata instead of the dried carrot previously used in Egypt. The new larval medium consists of wheat bran, molasses, yeast, sodium benzoate, hydrochloric acid and tap water. This substitution reduced the production costs of pupae in our laboratories. The adults produced from this medium showed almost similar emergence, fecundity, fertility and longevity as those produced from carrot medium. New large larval breeding cabinet was constructed which improved the larval production and can help in mass production purposes. Large oviposition cage was also used instead of the small ones previously used in Egypt. Six field cages made of wire screen, glass and wood were constructed to conduct semi field experiments on the competitiveness of the irradiated males. Competitiveness decreased with increased dose, doses of 5-9 krad led to almost similar reduction in egg hatch. Ratios of 13:13:1:1 and 2:2:1:1 (treated males : treated females : untreated males : untreated females) were tested in the field cages. There was no clear indication of whether male competitiveness of a particular dose was affected by the ratio of irradiated males to untreated males and females. Generally competitiveness of the irradiated males decreased by time. Flight range of the irradiated (9 krad) tagged flies was found to be 700 m within an orchard. Flies released in an orchard did not reach another orchard 700 m far from the release point

    This exploratory study examined how estimates of one's fruit and vegetable intake in childhood are related to 3 current dietary behaviors among African American women: intake of fruits and vegetables, exposure to and preference for fruits and vegetables, and preference for trying new foods. Baseline data from a randomized dietary intervention trial. Ten urban public health centers in St. Louis, Missouri. 1227 African American women. A 33-item fruit and vegetable food frequency questionnaire, items measuring estimates of childhood fruit and vegetable intake, adult fruit and vegetable intake, exposure to and preference for fruit and vegetable, and preference for trying new foods. Linear regression evaluated the association between predictors and continuous measures; logistic regression determined the association between predictors and categorical measures. Estimates of one's vegetable intake as a child were significantly related to exposure and preference for both fruits and vegetables, trying of new foods, and intake of both fruits and vegetables in adulthood. Estimates of eating fruit as a child were not significantly associated with these adult dietary behaviors. Developmental influences on adult dietary patterns may be stronger for vegetables than fruits among African American women. Additional emphasis is needed regarding exposure to and preference for vegetable intake in childhood.

CVT has various causes including genetic and acquired prothrombotic disorders and it usually has a favorable outcome with a low rate of thrombotic recurrence and mortality. Geographical and ethnic variations between populations may result in different distribution of CVT etiologies leading to different pathophysiological mechanisms and clinical presentations. In CVT series reported mostly from the Americas and the western European countries BD is not reported as a common cause of CVT. However it can be discerned as a frequent cause of CVT in BD series. Due to the high prevalence of BD in the southeast Mediterranean region BD is a frequent cause of CVT in the area. Discerning characteristics of patients with BD and CVT have been reported previously and these might be helpful in guiding diagnosis and treatment of CVT especially in this part of the world.

    Three approaches to developing a genetic sexing technique for the Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann), are discussed. Laboratory studies in late third instar larvae of the medfly revealed a potential for dieldrin resistance. A programme of sib selection produced the DiR strain, more than 60x resistante to dieldrin with cross-resistance to other cyclodienes, HCH, malathion and permethrin. Adults were not resistant. Crosses showed dieldrin resistance to be monofactorial, subject to a modifying effect from the genetic background on the expression of the homozygote. The 'backcrossing with selection' technique was used to separate dieldrin and malathion resistance but, in the process, resistance to both insecticides was lost after four to eight generations. Attempts to induce male linkage of the R gene by X irradiation were unsuccessful. Further genetic studies on resistance are recommended. With a view to producing an ethanol sensitive strain homozygous for an ADH null mutation (Adh - /Adh - ), pentenol selection of late third instar larvae was carried out, combined with ethyl methane sulphonate (EMS) treatments of adults. This produced a maximum of 15x tolerance of pentenol but no associated change in ethanol tolerance. Electrophoresis (PAGE) showed that two major ADH systems were at their most active in late third instar larvae. A gene causing a male distorted sex ratio in the progeny of males carrying it was isolated after X irradiation. The expression of the gene, which appears to be an example of meiotic drive, was enhanced by reducing the ambient temperature of parent flies from 26 deg. C+-2.0 to 18 deg. C+-1.5 during days 2-5 of pupal development. Selection to increase the expression of the gene produced families with less than 20% females but sex ratio tended to revert towards normal in subsequent generations. A potential is seen for producing strains in which sex ratio can be regulated by temperature. (author). 30 refs, 5 figs, 2

    The report covers a period of five years of studies on the genetics of the Mediterranean fruit fly (medfly), Ceratitis capitata (Wied.), and genetic sexing. Fourteen morphological mutants were isolated during that period, including gr, ru, ro Sr, Sp, ew, br, sb and six yet unstudied mutants. Additional data were accumulated on genetic recombination between the various marked loci in males and females, and genetic maps were constructed. Recombination in males were found to be rather common in the medfly and not associated with the presence of chromosomal aberrations or with a particular chromosome. It seemed, however, that the dominant mutants that have been studied had a higher frequency of recombination in males, which almost matched the recombination levels encountered in the females. Initial steps towards the construction of genetic sexing strains were conducted. Selection for resistance to certain chemicals (potassium sorbate, Avermectin and Cyromazine) was carried out with limited success. Lines with high immunity to the three chemicals were established, and the mode of inheritance to Cyromazine and potassium sorbate was studied. Indications were that Cyromazine resistance was recessive and governed by a single gene whereas potassium sorbate resistance seemed to be a quantitative trait. (author). 14 refs, 8 tabs

    Sterile male insects, mass-reared and released as part of sterile insect technique (SIT) programs, must survive long enough in the field to mature sexually and compete effectively with wild males for wild females. An often reported problem in Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann) SIT programs is that numbers of released sterile males decrease rapidly in the field for various reasons, including losses to different types of predators. This is a serious issue in view that most operational programs release sterile flies at an age when they are still immature. Previous field and field-cage tests have confirmed that flies of laboratory strains are less able to evade predators than wild flies. Such tests involve, however, considerable manipulation and observation of predators and are therefore not suitable for routine measurements of predator evasion. Here we describe a simple quality control method with aspirators to measure agility in medflies and show that this parameter is related to the capacity of flies to evade predators. Although further standardization of the test is necessary to allow more accurate inter-strain comparisons, results confirm the relevance of measuring predator evasion in mass-reared medfly strains. Besides being a measure of this sterile male quality parameter, the described method could be used for the systematic selection of strains with a higher capacity for predator evasion. (author) [es

    The success of Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann) control programs integrating the sterile insect technique (SIT) is based on the capacity of released the sterile males to compete in the field for mates. The Islands of Madeira are composed of 2 populated islands (Madeira and Porto Santo) where the medfly is present. To evaluate the compatibility and sexual performance of sterile flies we conducted a series of field cage tests. At same time, the process of laboratory domestication was evaluated. 3 wild populations, one semi-wild strain, and 1 mass reared strain were evaluated: the wild populations of (1) Madeira Island (north coast), (2) Madeira Island (south coast), and (3) Porto Santo Island; (4) the semi-wild population after 7 to 10 generations of domestication in the laboratory (respectively, for first and second experiment); and (5) the genetic sexing strain in use at Madeira medfly facility (VIENNA 7mix2000). Field cage experiments showed that populations of all origins are mostly compatible. There were no significant differences among wild populations in sexual competitiveness. Semi-wild and mass-reared males performed significantly poorer in both experiments than wild males in achieving matings with wild females. The study indicates that there is no significant isolation among strains tested, although mating performance is reduced in mass-reared and semi-wild flies after 7 to 10 generations in the laboratory.

    The program of the fight against the Mediterranean fly of fruits ''SIT'' becomes increasingly efficient when one control his various factors well mainly the performances of the sterile males within the unit. In this present work, we adopted a method of breeding which could improve quality of the sterile males intended for releasing. This method consists in introducing certain beneficial bacteria (Pseudomonas, Citrobacter and Klebsiella) into the milieu of breeding according to different combinations. The effect of these bacteria was analyzed by carrying out various tests of quality control to determin the parameters of quality (Productivity, weight, Emergence, flying aptitude) and the parameters of reproduction (latency time, Duration of coupling and competitiveness). According to the results obtained, we could observe changes on the level of the parameters of quality. The addition of Pseudomonas alone in the milieu of breeding significantly decreased the quality of the produced flies while the addition of this same bacteria in partnership with Citrobacter and Klebsiella showed a beneficial effect on their host. This is observed through the remarkable improvement of the competitiveness of the fly. Thus we can conclude that the presence of the bacteria alone or in synergy enormously affects the fitness flies and consequently their sexual competitiveness. (Author)

    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

    The prevalence of obesity and being overweight is rising among adult Canadians and diet is recognised as one of the main causes of obesity. The consumption of fruit and vegetables is shown to be protective against obesity and being overweight but little is known about the association of fruit juice consumption and obesity and being overweight. The present study aimed to investigate the association between fruit juice consumption and self-reported body mass index (BMI) among adult Canadians. This analysis is based on the Canadian Community Health Survey, Cycle 3.1. A regression method was used to assess the association of fruit juice consumption with self-reported BMI in 18-64-year-old Canadians who had been adjusted for sex, age, total household income, education, self-rated health, and daily energy expenditure. Because the analysis is based on a cross-sectional dataset, it does not imply a cause and effect relationship. Almost 38.6% of adult Canadians reported a fruit juice intake of 0.5-1.4 times per day and 18.2% consumed fruit juice more than 1.5 times per day. Participants with normal weight were likely to consume more fruit juice than obese individuals. Regression analysis showed a negative association between fruit juice consumption and BMI after adjusting for age, sex, education, marital status, income, total fruit and vegetable intake, daily energy expenditure, and self-rated health. On average, for each daily serving of fruit juice, a -0.22 unit (95% confidence interval = -0.33 to -0.11) decrease in BMI was observed. The results obtained showed a moderate negative association between fruit juice intake and BMI, which may suggest that a moderate daily consumption of fruit juice is associated with normal weight status.

    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.

    To test the effects of descriptive norm and message framing on fruit intake (intentions) in Dutch adults. Randomized pretest-posttest study using a 2 × 2 design. Internet-based. Dutch adults recruited via leaflets and announcements on intranet and Internet and who provided immediate intention (n = 294) and 1-week follow-up intention and fruit intake data (n = 177). Messages combining information on intake of others (low vs high intake) with information about positive or negative outcomes of (in)sufficient fruit intake. Fruit intake intentions and fruit intake. Analyses of covariance. Those already consuming sufficient fruit and receiving negative information about insufficient fruit intake increased their motivation to consume sufficient fruit immediately (P = .03), but not at 1-week follow-up. Those who read positive information about sufficient fruit intake reported higher fruit consumption than those who read negative information about insufficient fruit intake (P = .03). This was stronger in those already consuming sufficient fruit. There were no effects of descriptive norm information (P > .19). Information about outcomes was more persuasive than descriptive majority norm information. Effects were generally stronger in those already consuming sufficient fruit.

    In view of the fact that, any undesirable effects of gamma irradiation with the sterilizing dose (90 Gy) on wings and mouth parts of the Mediterranean fruit fly, Ceratitis Capitata (Wied.), and their associated sensilla will lead indirectly to failure of irradiated males to disperse strongly, to seek out appropriate niches or to behave synchrony with wild males or to success in the courtship with females and/or to mate. Moreover, the fly may fail to suck the plant juice. Using the scanning electron microscopy, this study was investigated. The changes which occurred to the wings and mouth parts of the med fly may be due to the sterilizing dose. One pair of wings was found to have similar typical structures in both sexes differing non-significantly in their measurements. Three different types of located sensilla were observed on each wing namely; trichoid (type sharp and blunt tipped), chaetica (type 1, 2 and 3) and basiconica (type non-socket, socket and papillae). The distribution and measurements of these sensilla were described in the text. The study of the mouth parts of both sexes recorded that there was similar pattern except significant increase between the length of the proboscis of male and female. Four different types of located sensilla were found on the mouth parts of the med fly and their measurements were given in the text. Namely trichoid (type sharp), squameformia (type 1 and socket), chaetica (type 1) and basiconica (type non-socket) were observed. The distal region of the labium was very smooth and did not bear any kind of sensilla. Pupal irradiation with the sterilizing dose resulted in different malformations in both irradiated male and female adult wings and mouth parts and their associated sensilla. Some malformations were observed in the intraveins of the irradiated male wing and in the pseudo tracheae of irradiated female labella

    In field conditions, grapevine roots normally are colonized by arbuscular mycorrhizal fungi (AMF). However, little is published, from either morphological or molecular studies, on the species composition of these symbionts in production vineyards. The AMF biodiversity of two Piedmont vineyards (at Neive and Lessona), characterized by different soil features, was investigated by morphological and molecular analyses. Several morphotypes were identified from the two vineyard soils. Community composition of AMF, both in soil and root samples, was then analysed with molecular approach to amplify a portion (550 bp) of AM fungal SSU rDNA. Phylogenetic analyses show a different distribution of sequences from the two sites in the main glomeromycotan groups. In the Neive site, the Glomeraceae group A is the only one well represented whereas more groups were found at Lessona. Among the more representative operational taxonomic units (OTUs), only one related to the Glomus irregulare phylotype was shared between the two vineyard soils. The data obtained in this work together with similar results in literature on this important fruit crop reinforce the concept that the general AMF assemblage structure and composition in vineyards might be influenced more by soil type than by host plant features (age, vegetative stages) or management practices. © 2010 Society for Applied Microbiology and Blackwell Publishing Ltd.

  2. Selected factors affecting the quality of Mediterranean fruit fly used in sterile release programs

    Adult irradiation of ceratitis capitata (Wiedemann) males resulted in a lower degree of sterility and a higher degree of competitiveness compared to pupal irradiation. It was consistently observed with both adult and pupal irradiation that the increased level of sterility obtained with increasing dose was counteracted to the same extent by decreasing level of male competitiveness. In a test in which the marking efficiency and persistence of fluorescent powders was tested, best results were obtained with Tinopal-SFG. Marking did not have any adverse effect either on male competitiveness or on fly survival. Competitiveness of irradiated male flies decreased as their exposure to chilling increased. Chilling, however, did not have any adverse effect on fly survival

    The objective of this study was to develop suitable and economic diets for mass rearing of the Mediterranean fruit fly, Ceratitis capitata (Wied.) (Diptera: Tephritidae), larvae by testing alternative sources of protein and bulking agent. Two larval diet groups for laboratory rearing of the medfly were conducted in addition to the control diet. The first group kept the sources of bulking agent constant (wheat bran) while the kind and the ratio of sources of protein were changed (brewer's yeast, soybean, schemed milk and agar). In the second group, the fiber (used for filling the pillows) and a paste of cardboard eggs box trays were used instead of wheat bran as bulking agent against the yeast and soybean as protein sources. To investigate the effect of the new sources of bulking agent and the kind or the ratio of the protein sources on the development and viability of the medfly, larval duration, pupal recovery, pupal weight, adult emergence, and flight ability were checked. The larval duration, pupal weight, adult recovery and flight ability were unaffected when soybean or a mixture from yeast, soybean, schemed milk and agar as protein sources for larval diet were used. The larvae reared on diets based on schemed milk or agar as sources of protein did not complete their life cycle. The percent of pupal recovery of larvae reread on diets of soybean or a mixture of protein sources were not affected except when larvae were reared on diets based on a mixture of soybean and schemed milk or schemed milk and agar. Larval duration was extended by one to two days more than the control when the fiber or a mixture of it with bran or paste of cardboard of eggs box was used as bulking agent. A paste of cardboard eggs box as bulking agent led to the extension of the larval duration by more than four days than in control. Pupal recovery was significantly decreased at all diets of the second group except the diet containing a mixture of 4 % fiber and 10 % bran as bulking agent

    A rapid biochemical method for the determination of the sterility in males of the fruit fly, Ceratitis Capitata (Wied.) was established utilizing testosterone as a bio marker. Pupae (2 days before emergence) were irradiated at 90 Gy using a 60 Co-gamma-cell, unit. Testosterone level, measured by radioimmunoassay (RIA), in addition to sterility in irradiated male flies were compared to their corresponding values of the untreated control group. The data obtained revealed a highly significant decrease in the testosterone level associated with a highly significant decrease in sterility. The decrease in the hormone level was recognized during the different time intervals (24-120 hours after adult emergence). This bio marker (Testosterone) could be adopted as a rapid monitor for measurements of medfly male sterility before release in the field in a sterile insect technique (SIT) program

    Males of Ceratitis capitata Wied. previously reared on three different larval media (molasses, sugar and glucose) were irradiated as old pupae with 7, 9 and 11 krad of gamma radiation. Results indicated that egg hatchability and male survival did not differ significantly in the three media at the three applied doses. Mating competitiveness of 9 krad-irradiated males at the ratio 3:1:1 (irradiated males : normal males : normal females) did not differ when using the different larval diets. When pupae were irradiated with the three doses, each given at three different dose rates, i.e. 7, 30 and 97 rad/s, a gradual decrease in egg hatchability was observed as the dose rate was increased. Adult survival was not affected by differences in either dose rate or in the radiation dose. Mating competitiveness of 9 krad-irradiated males was not affected by changes in dose rate. Old pupae were irradiated with 9 krad in three fractions at one-day interval between each treatment. Egg hatchability, male survival and male competitiveness did not differ significantly from those obtained when the dose was given in one treatment. Pupal incubation at different temperatures for two hours or two days did not affect egg hatchability in the non-irradiated group. On the other hand, pupal incubation at both 5/sup 0/ or 15/sup 0/C either for two hours or two days prior to irradiation resulted generally in a significant reduction in the percentages of sterility compared with 25/sup 0/C. Practically, there was no effect on male survival of either the temperature or the incubation period to which the pupae were exposed prior to irradiation. However, the male competitiveness was better when the pupae were incubated at 5/sup 0/ or 15/sup 0/C for two days rather than for two hours.

    The MP (male producing) factor, which shows temperature sensitive meiotic drive favoring the Y chromosome, proved to be highly variable in spermatozoal deficiency in different cysts within a single testis. However, the overall loss of sperm corresponded almost precisely with the loss of females. The minimum proportion of females consistently obtained in inbred lines was about 30-35%. On the basis of parallel studies with the mosquito Aedes aegypti, variability between cysts is open to interpretation in terms of different rates of senescence. The T:Y(wp + )30C genetic sexing strain, which is designed to generate males with brown (wild type) puparia and females with white puparia, was contaminated artificially in a series of population experiments to investigate the pattern of breakdown. Wild type contamination with either sex caused an increase of brown pupae. The sex ratio became progressively distorted in favour of females after contamination with females, mated or unmated, but not after male contamination. The experiments revealed evidence of a low frequency of natural recombination between wp + and the translocation breakpoint on the Y chromosome, shown by the appearance of wp males. The frequency of male recombination (r) and the selection coefficient (s) against wp/wp were measured over 11 generations. The best fit to the observed data was obtained with r = (0.14 ± 0.04)% and s=(26.0 ± 2.7)%. Using these estimates to predict the frequency of wp + females and wp males for up to 100 generations, it was concluded that white males would never exceed 0.5% whereas the frequency of brown females was expected to exceed 33% after 25 generations. Published data on the mass reared strain, maintained with a population size of 240,000 adult flies, were subjected to the same analysis. A higher value of s between (38.0 ± 3.2)% and (52.0 ± 0.3)% was obtained under these conditions. Electrophoretic studies on esterases revealed a significantly higher activity in a recently

    The Mediterranean fruit fly or medfly, Ceratitis capitata Wiedemann, is the single most important pest species affecting fresh fruits and vegetables within the Mediterranean region, but especially the Near East. For a wide range of commercial crops, including most citrus varieties, mangoes, grapes, apples, peaches, apricots, pears, plums, figs, dates, persimmons, papayas, peppers and tomatoes, it is the only economically important fruit fly in the region. This document, prepared at the request of Member States in the Near East region and developed by a group on international experts in fruit fly control, outlines plans to eradicate the medfly from three subregions of the Near East. The objective is the eradication of the medfly and establishment of fruit fly free areas within participating countries in order to reduce pesticide applications and to enable fresh fruit exports without post-harvest treatments. 12 refs, 6 figs, 19 tabs

    The average American child eats fewer fruits than recommended. Although taste is the primary motivator for food intake among children, little research has systematically measured children's liking of fruit and determined whether their preferences differ from adults. We phenotyped 49 children and their mothers to determine: (1) their liking of the taste of 3 blueberry cultivars ("Arcadia," "Keecrisp," and "Kestrel") from 2 harvests for which total soluble solids were determined using a handheld Brix refractometer; (2) the association between liking and blueberry sugar content; and (3) the most preferred level of fructose, one of the primary sugars in blueberry fruit. Multiple methods, identical for all participants, assessed which cultivar they liked best. Dietary intake, determined via 24-h dietary recall, revealed most children (73%) and adults (92%) did not meet dietary guidelines for fruit intake. We found that during the 1st harvest, Keecrisp was sweeter by 4° Brix than either Arcadia or Kestrel and was the cultivar most preferred by both children and adults. For the 2nd harvest, mothers liked each of the cultivars equally, but children preferred Arcadia, which was 2° Brix sweeter than the other 2 cultivars. Like other sugars, children's most preferred concentration of fructose was significantly higher than that of adults. In sum, children appear to be more sensitive to smaller variations in sweetness than are adults. Identifying drivers of fruit preference and assessing children's liking for whole fruits are important steps in developing strategies to increase fruit consumption among children. © 2017 Institute of Food Technologists®.

This study aimed to compare the intake of fruits and vegetables in adult malesand females of Isfahan and to assess its association with personal and demographic factors,as well as seasons.METHODS: This cross-sectional study was performed on 123 healthy adults (64 malesand 59 females during the cold season (fall and winter and warm seasons (spring andsummer. Study samples were aged 30 to 60 years and were residents of Isfahan. Fruit andvegetable consumption was assessed using a 110-item semi-quantitative food frequencyquestionnaire on fruits and vegetables. Validity of the questionnaire was evaluated in a pilotstudy through comparison with two 24-hour food recalls and four food diaries. Meanconsumption of fruits and vegetables was analyzed in males and females, as well as in ageand educational groups. The relationship between the amount of fruit and vegetableconsumption and different factors including age, sex, level of education and occupation wasdetermined through stepwise linear regression.RESULTS: Mean fruit consumption in men and women in cold seasons was 275.3±100.8and 234.5±116.5 grams per day, respectively (P<0.05, and in warm seasons 217.6±95.5and 185.3±77.1 grams per day, respectively (P<0.05.

    Through genetic and molecular manipulations, strains can be developed that are more suitable for the sterile insect technique (SIT). In this chapter the development of genetic sexing strains (GSSs) is given as an example. GSSs increase the effectiveness of area-wide integrated pest management (AW-IPM) programmes that use the SIT by enabling the large-scale release of only sterile males. For species that transmit disease, the removal of females is mandatory. For the Mediterranean fruit fly Ceratitis capitata (Wiedemann), genetic sexing systems have been developed; they are stable enough to be used in operational programmes for extended periods of time. Until recently, the only way to generate such strains was through Mendelian genetics. In this chapter, the basic principle of translocation-based sexing strains is described, and Mediterranean fruit fly strains are used as examples to indicate the problems encountered in such strains. Furthermore, the strategies used to solve these problems are described. The advantages of following molecular strategies in the future development of sexing strains are outlined, especially for species where little basic knowledge of genetics exists. (author)

    Obesity and metabolic syndrome (MetS) are key risk factors for chronic disease. Dietary patterns are critical in the incidence and persistence of obesity and MetS, yet there is few data linking diet to obesity and MetS in Chile. Our objective was to use a locally validated diet index to evaluate adherence to a Mediterranean dietary pattern and its correlations with overweight/obesity (OW/O) and MetS prevalence in Chilean adults. We conducted a nationwide, cross-sectional online survey of Chilean adults with complete self-reported diet and body mass index data ( n = 24,882). A subsample of 4348 users (17.5%) had valid MetS data. An inverse association was observed between adherence to Mediterranean diet and OW/O and MetS prevalence. As diet quality decreased from healthy, to moderately-healthy, to unhealthy, prevalence increased from 44.8, 51.1, to 60.9% for OW/O and from 13.4, 18.5, to 28.9% for MetS ( p -values diet groups in comparison to the healthy diet group. This study represents the first report on the relationship between Mediterranean diet and chronic disease risk in Chile. It suggests that the Mediterranean diet may be applied to manage chronic disease risk beyond the Mediterranean basin.

    To assess whether state-sponsored agricultural marketing programs had a positive influence on adult consumers' fruit and vegetable consumption. Differences in fruit and vegetable consumption between 2000 and 2005 in states that initiated marketing campaigns during this period and those that did not were examined. A representative sample (n  =  237,320) of adults aged 18 and older from states with and without marketing programs was used. The study used data from the 2000 and 2005 Behavioral Risk Factor Surveillance System. The number of fruit and vegetable servings per week and the percentage of respondents consuming five or more servings of fruits and vegetables per day were examined. Between-subjects analysis of variance and logistic regression. In the absence of a marketing campaign, there was a significant decrease in fruit and vegetable consumption between 2000 and 2005. In states with campaigns, consumption remained stable or increased. Marketing effects were stronger for women than for men. Conclusions . State-sponsored agricultural marketing programs had favorable effects on consumers' consumption of fruits and vegetables.

    This project investigated how individual differences in the big-five personality traits (neuroticism, extraversion, openness to experience, conscientiousness, and agreeableness) predicted plant-food consumption in young adults. A total of 1073 participants from two samples of young adults aged 17-25 reported their daily servings of fruits, vegetables, and two unhealthy foods for comparison purposes using an Internet daily diary for 21 or 13 days (micro-longitudinal, correlational design). Participants also completed the Neuroticism, Extraversion, Openness Five Factor Inventory (NEO-FFI) measure of personality, and demographic covariates including gender, age, ethnicity, and body mass index (BMI). Analyses used hierarchical regression to predict average daily fruit and vegetable consumption as separate dependent variables from the demographic covariates (step 1) and the five personality traits (step 2). Results showed that young adults higher in openness and extraversion, and to some extent conscientiousness, ate more fruits and vegetables than their less open, less extraverted, and less conscientious peers. Neuroticism and agreeableness were unrelated to fruit and vegetable consumption. These associations were unique to eating fruit and vegetables and mostly did not extend to unhealthy foods tested. Young adult women also ate more fruit and vegetables than young adult men. Results suggest that traits associated with greater intellect, curiosity, and social engagement (openness and extraversion), and to a lesser extent, discipline (conscientiousness) are associated with greater plant-food consumption in this population. Findings reinforce the importance of personality in establishing healthy dietary habits in young adulthood that could translate into better health outcomes later in life.

    The Mediterranean fruit fly (medfly) is the only fruit fly of economic importance affecting a large number of fruits and vegetables in the Maghreb (Algeria, Libyan Arab Jamahiriya, Morocco and Tunisia). The medfly causes losses of fresh fruit and vegetables in this region of about US $90 million each year. Therefore, eradication of this pest at this time would be very beneficial. Technologies are available to eradicate the medfly which will have no significant negative environmental impacts, and they can be used to accomplish eradication at reasonable cost. This report outlines the procedures available to eradicate the medfly from the Magherb with primary reliance on the use of sterile flies. A large fruit fly rearing facility, of modular design, must be constructed in the Mediterranean Basin and outside the Maghreb to produce and sterilize flies.

  1. Feeding of European pilchard (Sardina pilchardus in the northwestern Mediterranean: from late larvae to adults

    Full Text Available We assessed the relative importance of different prey types of the European pilchard (European sardine from the late larval to the adult stage. Two different methodologies for analysing stomach contents were used to describe the trophic dynamics of sardine and the relationship of sardine feeding behaviour with the ontogenetic development of body structures used for feeding, such as gill rakers and pyloric caeca. This information is essential to accurately depict the use of the planktonic resources in the area by sardine and to discuss the extent to which the sardine population could be affected by environmental changes in the Mediterranean Sea. We showed that cladocerans in summer and diatoms in winter were numerically the most important prey types for both juveniles and adults. However, decapod larvae were the most important prey during all seasons in terms of carbon content. Accordingly, differences in methodology should be considered in the analysis of sardine diets. An analysis of the composition of the plankton showed that small copepods were strongly selected by sardines at all ages and in both seasons. We also observed that the pyloric caeca began to grow when the sardines were approximately 4-5 cm standard length (SL and ended their development when the sardines reached approximately 8 cm SL, whereas the gill rakers appeared to be completely functional when the sardines reached 7 cm SL. Therefore, filter feeding of small particles could be performed with total efficacy beginning at 7-8 cm SL. In view of the energetic advantage of filter feeding in a well-adapted filter-feeding species such as sardine, the prospective limited availability of small particles hypothesized by certain authors for the Mediterranean could have negative consequences for sardine. This study demonstrates that sardine populations, given their extremely high dependence on the lower marine trophic levels, could be strongly affected by alterations in the environment

Methods We conducted a secondary data analysis of the baseline data (2014 of the Study on Obesity, Sarcopenia and Fragility in older adults affiliated with the Mexican Institute of Social Security. The study included 948 adults who were ≥60 years of age. Multiple Poisson regression was performed. Results Routine consumption of fruits and vegetables was reported by 53.8 % of older adults, 42.7 % reported engaging in regular physical exercise and 23.1 % reported participating in both types of healthy behaviors. Women, adults with a stable income, those with a self-perception of good health and those with a history of physical exercise at the age of 50 years had an increased likelihood of engaging in healthy eating and regular physical activity. Conclusions Many older adults do not routinely consume fruits and vegetables or engage in regular physical exercise despite the fact that most have a fixed income and a social network. It is relevant to conduct research-based interventions that take into account the contextual factors to promote healthy behaviors.

  6. 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 present study has been conducted to assess the effect and interaction of various storage substrates and conditions on eggs of the Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann). Tests were carried out with the genetic sexing strain VIENNA 8/D53, a strain that carries a temperature sensitive lethal (tsl) mutation that allows the selective killing of female zygotes. This study identifies strategies to enhance the storage and transport conditions through assessment of effect on egg, pupal and adult survival in order to facilitate the establishment of satellite mass rearing facilities for the production of male medflies. Eggs were immersed in two different substrates and stored at different temperatures and for different time periods. Findings from this study suggest that egg storage periods, and to some extent, the storage substrates have significant effects on pupal and adult survival. For 72-h storage periods, the eggs preserved in agar solution at 10 deg. C produced the most pupae. There was an inverse relationship between the concentration of dissolved oxygen in the substrate during storage and the quality and survival of the stored/transported eggs. Apparently low levels of dissolved oxygen reduce metabolic rates, allowing the storage period to be prolonged. (author) [es

    In older adults, the Mediterranean diet is associated with lower risk of chronic diseases, but its association with health-related quality of life (HRQL) is still uncertain. This study assessed the association between the Mediterranean diet and HRQL in 2 prospective cohorts of individuals aged ≥60 years in Spain. The UAM-cohort (n = 2376) was selected in 2000/2001 and followed-up through 2003. At baseline, diet was collected with a food frequency questionnaire, which was used to develop an 8-item index of Mediterranean diet (UAM-MDP). The Seniors-ENRICA cohort (n = 1911) was recruited in 2008/2010 and followed-up through 2012. At baseline, a diet history was used to obtain food consumption. Mediterranean diet adherence was measured with the PREDIMED score and the Trichopoulou's Mediterranean Diet Score (MSD). HRQL was assessed, at baseline and at the end of follow-up, with the physical and mental component summaries (PCS and MCS) of the SF-36 questionnaire in the UAM-cohort, and the SF-12v.2 questionnaire in the Seniors-ENRICA cohort. Analyses were conducted with linear regression, and adjusted for the main confounders including baseline HRQL. In the UAM-cohort, no significant associations between the UAM-MDP and the PCS or the MCS were found. In the Seniors-ENRICA cohort, a higher PREDIMED score was associated with a slightly better PCS; when compared with the lowest tertile of PREDIMED score, the beta coefficient (95% confidence interval) for PCS was 0.55 (-0.48 to 1.59) in the second tertile, and 1.34 (0.21 to 2.47) in the highest tertile. However, the PREDIMED score was non-significantly associated with a better MCS score. The MSD did not show an association with either the PCS or the MCS. No clinically relevant association was found between the Mediterranean diet and HRQL in older adults in Spain.

    The purpose of this study was to evaluate the daily vegetable and fruit intake status of Korean adults and to examine the relationship of vegetable and fruit intake with bone metabolism. The vegetable and fruit intake of 542 healthy male and female adults was analyzed. Then, by selecting 51 targets from the subjects, the relation of vegetable and fruit intake with serum calcium, osteocalcin and deoxypyridinoline (DPD) excretion in urine was examined. The total vegetable intake per day was 397.7 g and 333.5 g by men and women respectively for the age group of 20-29, 366.9 g and 309.2 g respectively for the age group of 30-49, 378.4 g and 325.9 g respectively for the age group of 50-64. Of vegetable varieties, leafy and stem vegetables displayed the highest intake. The order of major intake items of vegetables and fruits was found to be Chinese cabbage kimchi, onion, radish, cucumber, and welsh onion for the age group of 20-29, watermelon, Chinese cabbage kimchi, peach, potato, and onion for the age group of 30-49 and watermelon, Chinese cabbage kimchi, tomato, potato, and peach for the age group of 50-64. Of 51 targets, β-carotene intake displayed a significantly negative correlation with serum osteocalcin. While caloric intake as well as protein, carbohydrate, calcium, phosphorous, zinc and total food intake displayed a significantly negative correlation with DPD excretion in urine, tuber vegetable intake displayed a significantly positive correlation with DPD excretion in urine. In the future, a study will be necessary to accurately explain the relevance of vegetable and fruit intake with bone mineral density and bone metabolism. Also, efforts will be required to increase vegetable and fruit intake.

    A low consumption of fruit and vegetables (F&V) represents a high burden on health. The present study evaluates sociodemographic, lifestyle and anthropometric determinants of an inadequate consumption of F&V (Diet was assessed by a validated food frequency questionnaire. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by logistic regression, after sex stratification and controlling for age, education, marital status, smoking, regular physical exercise and total energy intake. Older women and men had 37% and 67%, respectively, lower odds of inadequate F&V consumption (≥65 versus 12 versus excessive alcohol (women: ≥15 g day(-1) ; men: ≥30 g day(-1) ) presented a two- and four-fold higher probability of having inadequate F&V consumption compared to nondrinkers (OR = 1.95, 95% CI = 1.38-2.77 in women; OR = 4.40, 95% CI = 2.70-7.18 in men). In both sexes, an inadequate consumption of F&V was more frequently found in younger, less educated and less physically active subjects with smoking and drinking habits. Strategies aiming to increase F&V consumption should consider these target groups that present a clustering of unhealthy lifestyles. © 2013 The British Dietetic Association Ltd.

    The objective of this study was to identify demographic, social and structural factors associated with intake of fruit and vegetables in older adults in New Orleans, Louisiana. A cross-sectional randomly sampled, address-based telephone survey of households in Orleans Parish, Louisiana was conducted with the household's main grocery shopper. All participants were in the New Orleans metro area and were surveyed in 2011. Participants were 2,834 residents identified as the households' main grocery shopper in Orleans Parish, Louisiana. Participants were primarily female (75%), African-American (53%), approximately 10 percent of the sample reported receipt of government assistance. Approximately 37% of the sample was age 65 and older. Measures included a telephone administered survey assessing demographic characteristics, food intake, access to supermarkets and other food sources, transportation, self-reported health, and frequency of grocery shopping. Older adults consumed fewer fresh fruits and vegetables (FV) than younger adults (p<0.01). Bivariate associations with decreased FV included older age, receipt of government assistance, African American race, use of mobility aid, and poorer health. Multivariate factors associated with lower consumption include age, African American race, and poorer self-reported health. Women reported more fruit and vegetable consumption than men. FV consumption is associated with improved health and reduced mortality. Older adults are less likely to consume fruits and vegetables, therefore addressing reduced FV consumption in older adults is a potential target for improving health outcomes in older adults. Specifically targeting African Americans and those with poorer health, as well as males may be an important focus for interventions.

    Full Text Available Scarce water resources mainly in arid and semi-arid areas have caused an increasing interest for applying irrigation protocols aiming to reduce water spends. The effects of regulated deficit irrigation (RDI on the performance of apricot trees (Prunus armeniaca L. cv. “Búlida” were assessed in Murcia (SE Spain, during three consecutive growing seasons (2008-2010. The hypothesis was that RDI would not restrict yield but increase fruit quality while saving water. Two irrigation treatments were established: i control, irrigated to fully satisfy crop water requirements (100% ETc and ii RDI, that reduced the amount of applied water to: a 40% of ETc at flowering and stage I of fruit growth; b 60% of ETc during the stage II of fruit growth and c 50% and 25% of ETc during the late postharvest period (from 60 days after harvest. Stem water potential, gas exchanges, trunk cross-sectional area (TCSA, fruit diameter, yield and fruit quality traits were determined. Vegetative growth was decreased by the use of RDI (12% less TCSA on average for the three years, whereas yield was unaffected. In addition, some qualitative characteristics of the fruits, such as the level of soluble solids, sweetness/acidity relation and fruit colour, were improved by the use of RDI. These results and average water savings of approximately 30%, lead us to conclude that RDI strategies are a possible solution for irrigation management in areas with water shortages, such as arid and semi-arid environments.

    The Mediterranean diet has been reported to be inversely associated with incident metabolic syndrome (MetSyn) among older adults; however, this association has not been studied in young African American and white adults. The objective of the present study was to evaluate the association of a modified Mediterranean diet (mMedDiet) score with the 25-year incidence of the MetSyn in 4713 African American and white adults enrolled in the Coronary Artery Risk Development in Young Adults (CARDIA) study. A diet history questionnaire was used to assess dietary intake at baseline, year 7 and year 20 and a mMedDiet score was created. Cardiovascular risk factors were measured at multiple examinations over 25 years. The MetSyn was defined according to the National Cholesterol Education Program Adult Treatment Panel III (ATP III) criteria. Cox proportional-hazards regression analysis was use to evaluate associations for incident MetSyn across the mMedDiet score categories adjusting for demographic characteristics, lifestyle factors and BMI. Higher mMedDiet scores represented adherence to a dietary pattern rich in fruit, vegetables, whole grains, nuts and fish, but poor in red and processed meat and snack foods. The incidence of MetSyn components (abdominal obesity, elevated TAG concentrations and low HDL-cholesterol concentrations) was lower in those with higher mMedDiet scores than in those with lower scores. Furthermore, the incidence of the MetSyn was lower across the five mMedDiet score categories; the hazard ratios and 95 % CI from category 1 to category 5 were 1·0; 0·94 (0·76, 1·15); 0·84 (0·68, 1·04); 0·73 (0·58, 0·92); and 0·72 (0·54, 0·96), respectively (P trend= 0·005). These findings suggest that the risk of developing the MetSyn is lower when consuming a diet rich in fruit, vegetables, whole grains, nuts and fish.

    Mass production of the Mediterranean fruit fly (Medfly) larvae, Ceratitis capitata Wiedemann, requires a rearing diet (Tanaka et al. 1969 1970) of which the nutrient requirements and digestibility have not been established. Setbacks in rearing productivity from the expected 100% yield to as low as 3% yield may occasionally be directly attributed to insecticide contamination or a variety of possible cause(s) (Kobayashi, 1993). These causes include inadequate nutrition, poor diet formulation, overcrowding of either microorganisms or Drosophila, or to the inherent processes of oxidative or microbial deterioration of nutrients. The purpose of this study was to establish the nutritional status of the Mediterranean fruit fly diet through a material balance study for changes in proximate composition (i.e., moisture, protein, fat, ash, carbohydrates), amino acids, minerals between fresh and spent diets, and in the fruit fly larvae themselves

    This study aimed to explore the potential associations of adherence to the Mediterranean diet with gut microbiota characteristics and gastrointestinal symptomatology in an adult population. Other long-term dietary habits (e.g. consumption of snacks and junk food or stimulant intake) were also evaluated in terms of the gut microbiota profile. Participants (n 120) underwent anthropometric, dietary, physical activity and lifestyle evaluation. Adherence to the Mediterranean diet was assessed using a Mediterranean diet score, the MedDietScore, and subjects were classified into three tertiles according to individual adherence scoring. Gut microbiota composition was determined using quantitative PCR and plate-count techniques, and faecal SCFA were analysed using GC. Gastrointestinal symptoms were also evaluated. Participants with a high adherence to the Mediterranean diet had lower Escherichia coli counts (P=0·022), a higher bifidobacteria:E. coli ratio (P=0·025), increased levels and prevalence of Candida albicans (P=0·039 and P=0·050, respectively), greater molar ratio of acetate (P=0·009), higher defaecation frequency (P=0·028) and a more pronounced gastrointestinal symptomatology compared with those reporting low adherence. A lower molar ratio of valerate was also observed in the case of high adherence to the Mediterranean diet compared with the other two tertiles (P for trend=0·005). Positive correlations of MedDietScore with gastrointestinal symptoms, faecal moisture, total bacteria, bifidobacteria:E. coli ratio, relative share of Bacteroides, C. albicans and total SCFA, as well as negative associations with cultivable E. coli levels and valerate were indicated. Fast food consumption was characterised by suppressed representation of lactobacilli and butyrate-producing bacteria. In conclusion, our findings support a link between adherence to the Mediterranean diet and gut microbiota characteristics.

    The purpose of this study was to develop a substantive theory expressing the meanings couples associated with eating fruits and vegetables. This inductive qualitative study was based on a grounded theory approach and employed the constant comparison method of data analysis. Data were collected using semistructured individual interviews and a life history approach. Ten adult couples, aged 20 to 60 years, with and without children, all of whom were born in North America, were recruited using modified snowball sampling. Two overarching themes emerged. The "should syndrome" describes a morality concerning fruit and vegetable consumption arising from a tension between the low status of these foods in participants' childhood homes and their contemporary idealized status. The creation of couple gastronomies expresses couples'efforts to construct their own food norms and practices within a context of changes in social norms and fruit and vegetable availability. The substantive theory, making choices that balance their lives, conveys the dynamic processes involved in participants' fruit and vegetable choices. Future research will determine the transferability of the "should syndrome" and new couples' receptiveness to trying new fruits and vegetables. Understanding the changing contexts of food choice may help nutrition professionals better support healthful eating.

    To study how different meals contribute to intakes of fruits, vegetables, fish and whole grains in a group of Norwegian adults and in subgroups of this population. Moreover, to investigate the consequences of skipping the meal contributing most to the intake of each food group (main contributing meal). Cross-sectional dietary survey in Norwegian adults. Dietary data were collected using two non-consecutive telephone-administered 24 h recalls. The recorded meal types were breakfast, lunch, dinner, supper/evening meal and snacks. Nationwide, Norway (2010-2011). Adults aged 18-70 years (n 1787). Dinner was the main contributing meal for fish and vegetables, while snacks were the main contributing meal for fruit intake. For whole grains, breakfast was the main contributing meal. The main contributing meal did not change for any of the food groups when studying subgroups of the participants according to intake of each food group, educational level or age. A substantially lower intake of the food groups in question was found on days when the main contributing meal was skipped. Intakes of fruits, vegetables, fish and whole grains largely depend on one meal type. Inclusion of these foods in other meals in addition to the main contributing meal, preferably replacing energy-dense nutrient-poor foods, should be promoted.

    Full Text Available Abstract Background Few studies have evaluated the linkage between food cost and mortality among older adults. This study considers the hypothesis that greater food expenditure in general, and particularly on more nutritious plant and animal-derived foods, decreases mortality in older adults. Methods This study uses the 1999–2000 Elderly Nutrition and Health Survey in Taiwan and follows the cohort until 2008, collecting 24-hr dietary recall data for 1781 participants (874 men and 907 women aged 65 y or older. Using monthly mean national food prices and 24-hr recall, this study presents an estimate of daily expenditures for vegetable, fruit, animal-derived, and grain food categories. Participants were linked to the national death registry. Results Of the 1781 original participants, 625 died during the 10-y follow-up period. Among the 4 food categories, the fourth and fifth expenditure quintiles for vegetables and for fruits had the highest survival rates. After adjusting for co-variates, higher (Q4 vegetable and higher fruit (Q4 food expenditures referent to Q1 were significantly predictive of reduced mortality (HR = 0.55, 95% CI: 0.39-0.78 and HR = 0.64, 95% CI: 0.42–0.99, respectively and the risk decreased by 12% and 10% for every NT$15 (US$0.50 increase in their daily expenditures. Animal-derived and grain food spending was not predictive of mortality. Conclusion Greater and more achievable vegetable and fruit affordability may improve food security and longevity for older adults.

    Antioxidant vitamins have been postulated as a protective factor in asthma. The associations between the frequency of fresh fruit consumption in summer, and the prevalence of self-reported asthma symptoms were investigated. The analysis was based on 5,582 males and 5,770 females, born in England, Wales and Scotland between March 3-9, 1958 and aged 33 yrs at the time of survey. The 12-month period prevalence of wheeze and frequent wheeze were inversely associated with frequent intakes of fresh fruit and salad/raw vegetables and positively associated with smoking and lower social class. After adjustment for mutual confounding and sex, associations with smoking persisted, but those with social class and salad/raw vegetable consumption lost significance. The frequency of fresh fruit intake was no longer associated with wheeze after adjustment, but was inversely associated with frequent wheeze and speech-limiting attacks. The association with frequent wheeze differed significantly between smoking groups (never, former, current) and appeared to be confined to exsmokers and current smokers. These findings support postulated associations between infrequent fresh fruit consumption and the prevalence of frequent or severe asthma symptoms in adults. Associations appeared to be restricted to smokers, with effect modification as a more likely explanation of this pattern than residual confounding by smoking.

    Biologically based control methods, such as the Sterile Insect Technique (SIT), which relies on the sterilization by irradiation of large numbers of insects, is gaining an increasing role in the control of medfly in Mediterranean areas. However, the exposure of cells to ionizing radiation leads to the formation of reactive oxygen species (ROS) that are associated with radiation-induced cytotoxicity. Because of the serious damaging potential of ROS, cells depend on the elaboration of the antioxidant defense system (AODS), both enzymatic and non enzymatic oxidant defense mechanisms. Enzymes of antioxidative defense system – peroxidase, esterasase and alcohol dehydrogenase are known to play an important main role in endogenous cell protection from oxidative damage.The antioxidant Eselenis an exogenous antioxidant containing both selenium and vitamin E. It was added to the larval artificial diets of the Mediterranean fruit fly, C. capitata in various concentrations. The produced full grown pupae were exposed to gamma rays at dose rate of 90Gy (sterilizing dose) and are used during this experiment. The purpose of this study was to determine the effects of gamma-irradiation on C. capitata endogenous antioxidant activity (peroxidase, esterase and alcohol dehydrogenase and to examine whether the presence of eselen has the influence on activity of antioxidant and in reducing consequently the oxidative stress and tissue injury induced by gamma radiation in thefruit fly, C. capitata (Wied.). The results indicated that antioxidant pretreatments to the larval rearing dietand irradiation of the produced full grown pupae may have some beneficial effects against irradiation-induced injury to success the application of the sterile insect technique (SIT) for controlling the Med fly, C. capitata .

    Estimation of vitamin A, C, E and beta-carotene food sources, as well as its nutritional intake and density in adult Catalonian population. A cross-sectional study was conducted over 2,346 individuals obtained from the sample of Catalonian Survey of Nutritional Status aged 18 to 75 years old to estimate usual dietary intake of vitamins A, C, E and beta-carotene using two 24 hour dietary recalls administered in two periods (june-july and november-december of 1992). Replicated 24 hour Recalls allowed for estimation of usual intake. Calculation of food sources for vitamins encompassed three phases: foods transformation into nutrients, aggregation of foods in categories and sum of nutrients by food categories. Intake of vitamin A (equivalents of retinol of provitamin A and vitamin A), E, C were closely near or higher than RDA. Nutritional density of vitamin C, E and beta-carotene were higher in female group. Nutritional density was positively associated to age for vitamins C, E and beta-carotene. Addition fat was the first source of vitamin E and it reached 33.8% of total vitamin E intake. Vegetables contributed in 17.3 % to the total vitamin C, whereas fruits accounted for 57.9%. Fruits recached 40.6% of the total beta-carotene intake, whereas vegetables accounted for 34.8%. The major contributors of vitamin A were milk and dairy products. Nutritional intake of vitamin A, C and E are over the RDA parameters suggesting an healthy nutritional status that must be confirmed and ratify by biochemical assessment. Nutritional densities were higher in female gender than in males in vitamins C, E, and beta-carotene possibly due to a higher intake of total lipids in male gender than in females. Nutritional density was positively associated to age in the same group of vitamins, suggesting a higher intake of empty calories in younger group. Fruits and Vegetables accounted for more than 70% of vitamin C and beta-carotene and major contributors were citrics, carrots, tomatoes

    Predation is probably the most important male mortality factor in insect species with courtship displays that render males performing them conspicuous targets of predators. Sexually active Mediterranean fruit fly males, Ceratitis capitata (Wied.), aggregate in leks, where they participate in agonistic encounters and engage in visual, acoustic and pheromone-calling displays to attract receptive females. The objective of this study was to assess: a) whether sexually displaying C. capitata males in leks inside host and non-host foliage are subject to predation by the most prominent predators yellow-jacket wasps, Vespula germanica (F.), and if so, b) whether olfactory, visual or auditive stimuli are used by foraging wasps in locating male C. capitata prey. Studies were carried out in a citrus orchard and surroundings on the island of Chios, Greece. Observations were conducted using perforated containers hung within mulberry, fig or citrus foliage. Living C. capitata flies of different sex and either mature or immature were placed inside. Our results show that the yellowjacket wasps have learned to associate the presence of sexually active medfly males aggregated in leks with their prey's pheromone (kairomone). Foraging wasps, flying through the crowns of host trees, responded to the odour source of C. capitata male pheromone by approaching from downwind. Even inside dense citrus tree foliage, wasps keyed in on aggregations of pheromone-calling males using olfactory stimuli. Stimuli of visual and acoustic male signalling were only used at close range, after having followed the pheromone plume close to its source. Visual cues played a greater role in directing wasp foraging under more open and exposed host foliage conditions. Odour-based foraging of wasps inside host foliage in the mid-morning hours, when medfly male lekking activities peak, shifted gradually to a more visual-based host fruit patrolling in the afternoons to capture ovipositing and feeding medfly females

    Life-history attributes can impose differences on root system structures and properties related to nutrient and water uptake. Here, we assess whether plants with different post-fire regenerative strategies (resprouters, seeders and seeder-resprouters) differ in the topological and morphological properties of their root systems (external path, altitude, magnitude, topological index, specific root length, root length, root-to-shoot biomass ratio, length of the main axis of the root system and link length). To achieve these objectives, we sampled individuals from eight woody species in a shrubland located in the western Mediterranean Basin. We sampled the adult root systems using manual field excavation with the aid of an air compressor. The results indicate that resprouters have a higher root-to-shoot ratio, confirming their higher ability to store water, starch and nutrients and to invest in the belowground biomass. Moreover, this pattern would allow them to explore deeper parts of the soil layers. Seeder species would benefit from a higher specific root length, pointing to increased relative root growth and water uptake rates. This study confirms that seeders and resprouters may differ in nutrient and water uptake ability according to the characteristics of their root system. Species that can both resprout and establish seedlings after fire had different patterns of root system structure; in particular, root:shoot ratio was more similar to resprouters and specific root length was closer to seeders, supporting the distinct functional performance of this type of species. © 2013 German Botanical Society and The Royal Botanical Society of the Netherlands.

    Objectives: To assess prevailing food patterns, and its association with physical activity and fitness among Spanish older adults. Methods: Cross-sectional study in Spain, collecting data from a sample ( n = 380; 54% female) aged 55-80 years (men) and 60-80 years (women) with no previously documented cardiovascular disease. Body weight, body fat and waist circumference were assessed. Physical activity performed was measured using the Minnesota Leisure-time Physical Activity Questionnaire (LTPA). Physical fitness was assessed using a validated physical fitness test battery. Food consumption was assessed by a validated semi-quantitative food-frequency questionnaire. Factor analysis identified two major dietary food patterns: "Western" (WDP) and "Mediterranean" (MDP) dietary patterns. Results: Participants in MDP's fourth quartile were classified in the second (men) and third (men and women) tertile of LTPA. After adjusting for age, body fat, waist-to-height ratio, and METs, in both sexes, a negative significant association was found between 30-s Chair stand and 6-min walking test, a positive significant association was found between 30-m Gait speed and 8-foot Time Up-and-Go (except in men) tests with WDP. The 30-m Gait speed test was negatively associated with MDP in men. Conclusions: MDP is associated with more time spent on LTPA, and this association was independent of body composition and a fast gait speed in men. WDP is associated with slower gait speed and lower body strength, agility and aerobic endurance. MDP has protective effect on healthy physical fitness, and WDP may be a contributor to frailty.

    In this work, the agronomic behaviour and fruit quality of ten varieties of common fig were evaluated for the establishment of new commercial orchards destined for fresh consumption. The following traits were measured: annual yield, cumulative yield, trunk cross sectional area (TCSA) and yield efficiency of each variety, as well as weight, width, total soluble solids (TSS), pH, titratable acidity (TA) and maturation index (MI) of brebas and figs. The results show that ‘Banane’ and ‘Brown Turkey’ were the earliest to enter into production, and ‘Banane’ showed the highest annual yield in the 7th green (2014), with 76 kg/tree, followed by ‘Brown Turkey’ (57.6 kg/tree), ‘Cuello Dama Blanco’ (52 kg/tree) and ‘Colar Elche’ (39 kg/tree). On the other hand, 'Cuello Dama Blanco' and 'De Rey' exhibited the better organoleptic traits, with TSS and MI values ranged from 18.7 ºBrix and 203.3 MI (‘Cuello Dama Blanco’) to 20.4 ºBrix and 187.1 MI (‘De Rey’) for brebas and from 21.4 ºBrix and 278.7 (‘Cuello Dama Blanco’) to 23.3 ºBrix and 255.6 (‘De Rey’) for figs. This study will allow the fruit grower to select the most interesting and appropriate range of varieties based on market needs taking into account the ripening season (early, middle or late) and fruit colour (green, purple or black).

    There is sparse evidence on the relationship between the Mediterranean diet, Dietary Approaches to Stop Hypertension (DASH) style diet, and metabolic health, especially comparing cardiometabolic phenotypes among in normal weight and obese populations. We aimed to investigate the association of the Mediterranean diet scores (MDS) and DASH index with metabolically healthy obese (MHO) and metabolically obese normal weight (MONW) phenotypes in a representative U.S. MDS and DASH index were calculated using dietary data from 2767 adults aged 20-90 years without any prior diagnosis of cancer or cardiovascular disease from the National Health and Nutrition Examination Survey III, 1988-1994. MHO and MONW individuals were identified using fasting glucose, insulin resistance, blood pressure, triglycerides, C-reactive protein, and high-density lipoprotein-cholesterol. Higher MDS was associated with higher odds of MHO phenotype (odds ratio (OR) T3 vs T1 , 2.57 [95% confidence interval (CI), 1.04-6.35]; P trend = 0.04), and higher DASH index was associated with lower odds of MONW phenotype (OR T3 vs T1, 0.59 [95% CI, 0.38-0.93]; P trend = 0.03) only in the younger age group (Mediterranean diet or DASH style diet was favorably associated with MHO and MONW phenotypes only in the younger age group, suggesting that potential dietary intervention to prevent cardiometabolic disease differ by age group.

    Wheat bran and molasses were used in larval medium of the Mediterranean fruit fly, Ceratitis capitata instead of the dried carrot previously used in Egypt. The new larval medium consists of wheat bran, molasses, yeast, sodium benzoate, hydrochloric acid and tap water. This substitution reduced the production costs of pupae in our laboratories. The adults produced from this medium showed almost similar emergence, fecundity, fertility and longevity as those produced from carrot medium. New large larval breeding cabinet was constructed which improved the larval production and can help in mass production purposes. Large oviposition cage was also used instead of the small ones previously used in Egypt. Six field cages made of wire screen, glass and wood were constructed to conduct semi field experiments on the competitiveness of the irradiated males. Competitiveness decreased with increased dose, doses of 5-9 krad led to almost similar reduction in egg hatch. Ratios of 13:13:1:1 and 2:2:1:1 (treated males : treated females : untreated males : untreated females) were tested in the field cages. There was no clear indication of whether male competitiveness of a particular dose was affected by the ratio of irradiated males to untreated males and females. Generally competitiveness of the irradiated males decreased by time. Flight range of the irradiated (9 krad) tagged flies was found to be 700 m within an orchard. Flies released in an orchard did not reach another orchard 700 m far from the release point.

    Endometrial cancer is the fourth most common cancer in European women. The major risk factors for endometrial cancer are related to the exposure of endometrium to estrogens not opposed to progestogens, that can lead to a chronic endometrial inflammation. Diet may play a role in cancer risk by modulating chronic inflammation. In the framework of a case-control study, we recruited 297 women with newly diagnosed endometrial cancer and 307 controls from Northern Italy. Using logistic regression, we investigated the role of fruit and vegetable intake, adherence to the Mediterranean diet (MD), and the dietary inflammatory index (DII) in endometrial cancer risk. Women in the highest quintile of vegetable intake had a statistically significantly lower endometrial cancer risk (adjusted OR 5th quintile vs 1st quintile: 0.34, 95% CI 0.17-0.68). Women with high adherence to the MD had a risk of endometrial cancer that was about half that of women with low adherence to the MD (adjusted OR: 0.51, 95% CI 0.39-0.86). A protective effect was detected for all the lower quintiles of DII, with the highest protective effect seen for the lowest quintile (adjusted OR 5th quintile vs 1st quintile: 3.28, 95% CI 1.30-8.26). These results suggest that high vegetable intake, adherence to the MD, and a low DII are related to a lower endometrial cancer risk, with several putative connected biological mechanisms that strengthen the biological plausibility of this association.

    The sterile insect technique (SIT) is increasingly being used around the world to control Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), the Mediterranean fruit fly as part of an area-wide integrated approach. One option that may improve the effectiveness of the SIT, by increasing the sexual competitiveness of released sterile males, consists of feeding males protein during the post-teneral stage, a diet that increases sexual performance of wild males. We examine the effects of diet on the successive hurdles males must overcome in order to inseminate females, i.e., joining leks, copulating females, having their sperm stored and inhibition of female remating. In addition, we address the effects of diet on post-release foraging success, longevity, and the ability to withstand starvation. While protein feeding universally increases the sexual success of wild males, its effect on sterile males varies with strain, experimental settings, and environmental conditions. In some cases, treatments that resulted in the best sexual performance were significantly associated with increased vulnerability to starvation. However, no particular diet affected the ability of sterile males to find nutrients in the field when these where available. We suggest it may be better to release relatively short-lived flies that are highly competitive, rather than long-lived, sexually ineffective ones. (author) [es

    Objective The aim of this study was to evaluate the relationship between adherence to a Mediterranean-type diet and metabolic syndrome (MetS) in the Polish arm of the Health, Alcohol and Psychosocial factors In Eastern Europe (HAPIEE) cohort study. Materials/methods A cross-sectional survey including 8821 adults was conducted in Krakow, Poland. Food intake was evaluated through a validated food frequency questionnaire and adherence to the dietary pattern was assessed using a score specifically developed for non-Mediterranean countries (MedTypeDiet score). Linear and logistic regression models were performed to estimate beta and odds ratios (ORs) and 95% confidence intervals (CIs), respectively. Results Significant associations between the MedTypeDiet score and waist circumference (β = − 0.307 ± 0.239 cm), systolic blood pressure (β = − 0.440 ± 0.428 mmHg), and triglycerides (β = − 0.021 ± 0.016 mmol/L) were observed. After multivariable adjustment, individuals in the highest quartile of the score were less likely to have MetS, central obesity, high triglycerides, and hypertension. Increase of one standard deviation of the score was associated with 7% less odds of having MetS (OR 0.93, 95% CI: 0.88, 0.97). When analyzing the relation of single components of the MedTypeDiet score, wine, dairy products, and the total unsaturated:saturated fatty acids ratio were associated with MetS. Conclusions Adherence to a Mediterranean-like diet may decrease the risk of MetS also among non-Mediterranean populations. PMID:25752843

    The US Department of Agriculture launched ChooseMyPlate.gov nutrition recommendations designed to encourage increased fruit and vegetable intake, in part, as a strategy for improving weight control through the consumption of high-satiation foods. The purpose of this cross-sectional study was to assess the relationship between adults' reported daily intake of fruits and nonstarchy vegetables (ie, those thought to have the lowest energy density) expressed as a proportion of their total daily food intake and objectively measured cardiovascular and metabolic disease risk factors using data from the 2009-2010 National Health and Nutrition Examination Survey (NHANES). Physical activity was included as a moderator variable. This study employed a cross-sectional examination of 2009-2010 NHANES data to assess how daily fruit and nonstarchy vegetable intake was associated with anthropometric measures and cardiometabolic blood chemistry markers. Adults free of cardiac or metabolic disease (n=1,197) participated in 24-hour dietary recalls; a variety of cardiometabolic biomarkers and anthropometric measures were also collected from participants. Among participants with complete data on all variables, the ratio of the combined cup-equivalents of fruit and nonstarchy vegetable intake to the total gram weight of all foods consumed daily (F/V ratio) served as the primary independent variable. Main dependent measures included fasting glucose, insulin, glycosylated hemoglobin, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, total cholesterol, waist circumference, and body mass index. Demographic and behavioral predictors of the F/V ratio and the association between the F/V ratio and cardiometabolic disease risk factors were examined using multivariate regression. Body mass index (β=-2.58; 95% CI -3.88 to -1.28), waist circumference (β=-6.33; 95% CI -9.81 to -2.84), and insulin (β=-0.21; 95% CI -0.37 to -0.05) were inversely

    Nutritious diets that include sufficient intake of fruits and vegetables promote health and reduce risk for chronic diseases. The 2005 Dietary Guidelines for Americans recommend four to 13 servings of fruits and vegetables daily for energy intake levels of 1,000 to 3,200 kcal, including seven to 13 servings for 1,600 to 3,000 kcal/day as recommended for adults aged ≥25 years. The 2006-2007 Washington Adult Health Survey, a cross-sectional study designed to measure risk factors for cardiovascular disease among a representative sample of Washington State residents aged ≥25 years, included a food frequency questionnaire (FFQ). The FFQ included approximately 120 food items and summary questions for fruits and vegetables that were used to compute energy intake and two measures of fruit and vegetable intake. Measure 1 was computed as the sum of intake of individual FFQ fruit and vegetable items; Measure 2 combined the summary questions with selected individual FFQ fruit and vegetable items. Depending on the measure used, approximately 14% to 22% of 519 participants with complete information met the guidelines for fruits, 11% to 15% for vegetables, and 5% to 6% for both fruits and vegetables. Participants aged ≥65 years and women were more likely to meet recommendations, compared with younger participants and men. Despite decades of public health attention, the vast majority of Washington State residents do not consume the recommended amount of fruits or vegetables daily. These findings underscore the need for developing and evaluating new approaches to promote fruit and vegetable consumption. Copyright © 2012 Academy of Nutrition and Dietetics.

    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).

    In 2001, an outbreak of Mediterranean fruit fly in Adelaide was controlled by South Australian Government workers applying organophosphorus insecticides (OPs) to domestic gardens. Residents made claims of adverse effects associated with allegations that worker application practices were poor and led to contamination of homes, residents and pets. The concerns led to a Parliamentary enquiry, the suspension of OP applications for fruit fly control, and the investigation of alternative methods of combating fruit fly in metropolitan Adelaide. The extent of exposure of workers and residents was not estimated. This paper describes a simulated application of the OPs concerned (fenthion and malathion) with measurements of potential exposure through inhalation, dermal contact and deposition of pesticides on surfaces. The data were used as part of a toxicological risk assessment to determine the likely impact of the use of these insecticides. Malathion, used as a 1% suspension in a protein bait mixture, was found to have little potential for airborne exposure, although some workers were found to have up to 0.315 microg/cm(2) malathion deposited on overalls (principally on forearms) and over 500 microg deposited on liner gloves and hats, respectively. Risks to workers and residents were low, with exposures likely to be a small fraction of the acceptable daily intake. Fenthion, used as a 0.05% foliar cover spray, was found between 0.02 and 0.23 mg/m(3) in air 10 m downwind from spray activity and was unlikely to pose a significant risk to residents, since exposures were of short durations of up to 20 min. Personal air samples of spray workers averaged 0.55 mg/m(3) (Workplace Exposure Standard 0.20mg/m(3)). Since workers were usually engaged in spraying for a large proportion of the day, this demonstrates the need for respiratory protective equipment. Maximum deposition of fenthion on workers overalls ranged from 0.06 to over 0.20 microg/cm(2), although little was found on

    Cobalt-60 gamma irradiation pilot plant has been put into operation in 1999 at the National Center for nuclear scinces and technologies, Sidi-Thabet, Tunisia. An initial characterization of this pilot was performed to determine the overall performance of the irradiator in delivering absorbed dose to a product prior to routine processing, in particular sterilisation of medical devices and food irradiation. A new irradiation holder was recently installed; it was designed especially for the irradiation of pupae of the Meditterranean fruit fly. It consists of four turn plates which makes it possible to rotate the canisters holding the pupae within the radiation field. The axis of ratation is vertical and parallel to the source pencils. Prior to routine irradiation using the new irradiation holder, validation procedures are necessary to establish conditions of the irradiation within the specification. In the course of these procedures, detailed dose mapping on a vertical plane in the middel of the canister of insect pupae with bulk density of 0.446 g /cm3 was carried out for two irradiation configurations : fixed plates and turned plates. GafChromic dosimeter calibrated against Alanine / ESR dosimetry system was used for the dose measurements. The maximum and minimum dose locations were determined and the dose uniformity ratio calculated and discussed. Detailed analyses of the isodose curves and histogram of the frequency distribution of absorbed dose were also given. Transit dose and dose rate in the reference position inside the canister were measured using Fricke dosimeters. The results of measurements of absorbed dose and dose distribution in insect pupae do not show any significant difference in the dose uniformity ratio (U=Dmax / Dmin) between the two irradiation configurations. At the same time we observed with turned plates configuration an improvement of the homogeneity of the absorbed dose distribution in the insect pupae showed by the increasing of the pipae

    Thermal stress at one life stage can affect fitness at a later stage in ectotherms with complex life cycles. Most relevant studies have focused on extreme stress levels, but here we also show substantial fitness effects in a moth when pupae are exposed to a relatively mild and sublethal heat stress. We consider the impact of a 35°C heat stress of 2h in three geographically separate populations of the oriental fruit moth (OFM, Grapholita molesta) from northern, middle and southern China. Heat stress negatively affected fecundity but increased adult heat resistance and adult longevity. Fitness effects were mostly consistent across populations but there were also some population differences. In the Shenyang population from northern China, there was a hormetic effect of heat on female longevity not evident in the other populations. Adults from all populations had higher LT 50 s due to heat stress after pupal exposure to the sublethal stress. These results highlight that the pupal stage is a particularly sensitive window for development and they have implications for seasonal adaptation in uncertain environments as well as changes in pest dynamics under climate warming.

    To identify the trends of vegetables and fruits consumption among Chinese adults aged 18 to 44 years old from 1991 to 2011. Twenty four hour dietary recall data from China Health and Nutrition Survey (1991, 1993, 1997, 2000, 2004, 2006, 2009 and 2011) were used to identify the trends of vegetables and fruits consumption among Chinese between 18 and 44 years old. From 1991 to 2011, the proportion of daily consumption of vegetables rarely varied, while the vegetables intake declined significantly; and the proportion of daily consumption and intake of fruits kept increasing as follows. By 2011, the proportion of daily consumption and intake of vegetables and fruits among the respondents were 99.7%, 48.0%, 321.6 g/d, and 90.1 g/d respectively. A significant drop was found in the vegetables intake among the respondents against the vegetables intake as recommended by the Chinese dietary guidelines, up to 50.2% in 2011; a significant rise was found in the fruits intake of the respondents against the fruits intake as recommended by the said guidelines, up to 17.4% in 2011. The average daily intake of vegetables and fruits of young and middle-aged residents (18-44 age group) in nine provinces in China was found lower than that recommended in the Chinese dietary guidelines; in view of the high proportion of people having less vegetables and fruits intake that those recommended by the Chinese dietary guidelines, further measures are expected to encourage their vegetables and fruits intake.

    The incidence of age-related cognitive decline is rising considerably around the world. There is evidence from a number of recent cross-sectional and prospective studies indicating positive associations between the Mediterranean dietary pattern (MedDiet) and improved cognitive outcomes among the elderly including, reduced age-related cognitive decline and enhanced age-related cognitive performance. However, to date no study has validated these associations in healthy older adult populations (≥65 years and above) with randomised evidence. The main aim of the present study is to provide justified evidence regarding the efficacy of a MedDiet approach to safely reduce the onset of cognitive decline, and promote optimal cognitive performance among healthy older adults using rigorous, randomised intervention methodology. MedLey is a 6-month, randomised controlled 2-cohort parallel group intervention trial, with initial assessment at baseline and repeated every three months. A sample of 166 healthy Australian men and women aged 65 years and above, with normal cognitive function and proficient in English language were recruited from metropolitan Adelaide, South Australia for the study. Participants randomly allocated to the experimental group are required to maintain an intervention dietary pattern based from the traditional Cretan MedDiet (i.e. vegetables, fruits, olive oil, legumes, fish, whole grain cereals, nuts and seeds and low consumption of processed foods, dairy products, red meat and vegetable oils) for six months, while those participants allocated to the control group are asked to maintain their customary lifestyle and diet. The primary outcome of interest is the quantitative difference in age-related cognitive performance, as measured by latent variables (cognitive constructs) sensitive to normal ageing and diet (i.e. speed of processing, memory, attention, executive functions, visual spatial and visuomotor ability). Secondary outcomes include change in

    Full Text Available This study tested the psychological benefits of a 14-day preregistered clinical intervention to increase fruit and vegetable (FV consumption in 171 low-FV-consuming young adults (67% female, aged 18-25. Participants were randomly assigned into a diet-as-usual control condition, an ecological momentary intervention (EMI condition involving text message reminders to increase their FV consumption plus a voucher to purchase FV, or a fruit and vegetable intervention (FVI condition in which participants were given two additional daily servings of fresh FV to consume on top of their normal diet. Self-report outcome measures were depressive symptoms and anxiety measured pre- and post-intervention, and daily negative and positive mood, vitality, flourishing, and flourishing behaviors (curiosity, creativity, motivation assessed nightly using a smartphone survey. Vitamin C and carotenoids were measured from blood samples pre- and post-intervention, and psychological expectancies about the benefits of FV were measured post-intervention to test as mediators of psychological change. Only participants in the FVI condition showed improvements to their psychological well-being with increases in vitality, flourishing, and motivation across the 14-days relative to the other groups. No changes were found for depressive symptoms, anxiety, or mood. Intervention benefits were not mediated by vitamin C, carotenoids, or psychological expectancies. We conclude that providing young adults with high-quality FV, rather than reminding them to eat more FV (with a voucher to purchase FV, resulted in significant short-term improvements to their psychological well-being. These results provide initial proof-of-concept that giving young adults fresh fruit and vegetables to eat can have psychological benefits even over a brief period of time.Australian New Zealand Clinical Trials Registry ACTRN12615000183583.

    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

    several studies have found nutrients, including antioxidants, to be associated with sarcopenia. However, whether specific foods, such as vegetables and fruits, are associated with sarcopenia has not been studied. to examine the association of the frequency of vegetables and fruits consumption with sarcopenia in older people. this study used cross-sectional data from the Fourth Korea National Health and Nutrition Examination Survey in 2008-09. Subjects were community-dwelling 823 men and 1,089 women aged ≥65 years. Frequency of food group consumption was obtained by using the food frequency questionnaire. Body composition was measured with the dual-energy X-ray absorptiometry and sarcopenia was defined as appendicular lean mass adjusted for height and fat mass. Logistic regression was used to assess the association of the frequency of food group consumption with sarcopenia, controlling for sociodemographics and health-related variables. dietary intake of vegetables, fruits and both vegetables and fruits was associated with a significantly reduced risk of sarcopenia after controlling for covariates in men (P = 0.026 for trend, P = 0.012 for trend, P = 0.003 for trend, respectively). Men in the highest quintile, compared with those in the lowest quintile, of vegetables [odds ratio (OR) = 0.48; 95% confidence interval (CI): 0.24-0.95], fruits (OR = 0.30; 95% CI: 0.13-0.70) and vegetables and fruits consumption (OR = 0.32; 95% CI: 0.16-0.67) demonstrated a lower risk of sarcopenia. In women, high consumption of fruits demonstrated a lower risk of sarcopenia (OR = 0.39; 95% CI: 0.18-0.83). frequent vegetables and fruits consumption was inversely associated with sarcopenia in older adults. © The Author 2014.

    Data from an island-wide trapping survey and from test releases of 28 million medfly were used in the study. The flies were reared at 23 +-2 0 C and a 14-hr photoperiod, in organdy cylindrical cages containing 50,000-60,000 pupae/cage. The adult diet was a 3:1 enzymatic yeast hydrolysate: sugar mixture with water separate. The cages were kept for 15-17 days and produced ca. 6 x 10 6 eggs/cage. Pupae were produced on trays loaded with 1.5 kg. of specified medium, and yielded 17,000-20,000 pupae after 9-10 days. They were subsequently irradiated 24-28 hrs before emergence with 9 krad of γ-rays, and labelled. Pupae were packaged, at 21 of pupae/plastic bag. Details of final packaging, transport and release methods and rates are given. The absence of a suitable host of 2-3 months would be sufficient to break the medfly cycle. Data on larval infestation in sour and jaffa oranges, apricots and figs were obtained, the most dramatic difference in infestation between two villages being ovserved in figs.

    The sterile insect technique (SIT) is increasingly being used around the world to control Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), the Mediterranean fruit fly as part of an area-wide integrated approach. One option that may improve the effectiveness of the SIT, by increasing the sexual competitiveness of released sterile males, consists of feeding males protein during the post-teneral stage, a diet that increases sexual performance of wild males. We examine the effects of diet on the successive hurdles males must overcome in order to inseminate females, i.e., joining leks, copulating females, having their sperm stored and inhibition of female remating. In addition, we address the effects of diet on post-release foraging success, longevity, and the ability to withstand starvation. While protein feeding universally increases the sexual success of wild males, its effect on sterile males varies with strain, experimental settings, and environmental conditions. In some cases, treatments that resulted in the best sexual performance were significantly associated with increased vulnerability to starvation. However, no particular diet affected the ability of sterile males to find nutrients in the field when these where available. We suggest it may be better to release relatively short-lived flies that are highly competitive, rather than long-lived, sexually ineffective ones.

    Full Text Available Objectives By the end of the 2000s, the economic situation in many European countries started to deteriorate, generating financial uncertainty, social insecurity and worse health status. The aim of the present study was to investigate how the recent financial crisis has affected the lifestyle health determinants and behaviours of older adults living in the Mediterranean islands. Methods From 2005 to 2015, a population-based, multi-stage convenience sampling method was used to voluntarily enrol 2749 older adults (50% men from 20 Mediterranean islands and the rural area of the Mani peninsula. Lifestyle status was evaluated as the cumulative score of four components (range, 0 to 6, that is, smoking habits, diet quality (MedDietScore, depression status (Geriatric Depression Scale and physical activity. Results Older Mediterranean people enrolled in the study from 2009 onwards showed social isolation and increased smoking, were more prone to depressive symptoms, and adopted less healthy dietary habits, as compared to their counterparts participating earlier in the study (p<0.05, irrespective of age, gender, several clinical characteristics, or socioeconomic status of the participants (an almost 50% adjusted increase in the lifestyle score from before 2009 to after 2009, p<0.001. Conclusions A shift towards less healthy behaviours was noticeable after the economic crisis had commenced. Public health interventions should focus on older adults, particularly of lower socioeconomic levels, in order to effectively reduce the burden of cardiometabolic disease at the population level.

    Full Text Available Abstract Background Dietary habits in Morocco are changing and the causes are not well understood. This study aimed to analyse socio-demographic factors associated with adherence to the Mediterranean diet (MeDi in a national random sample of the adult Moroccan population. Methods The data collected in this cross-sectional survey included socio-demographic factors and a food frequency questionnaire. MeDi adherence was assessed in 2214 individuals with complete dietary data. MeDi adherence was measured according to a simplified MeDi score based on the weekly frequency of intake of eight food groups (vegetables, legumes, fruits, cereal or potatoes, fish, red meat, dairy products and olive oil with the use of the sex specific medians of the sample as cut-offs. A value of 0 or 1 was assigned to consumption of each component according to its presumed detrimental or beneficial effect on health. Logistic regression was used to estimate the association between MeDi adherence (low score 1-4 vs. high 5-8 and other factors. Results Mean age of the sample was 41.4 (standard deviation 15.3 years, 45.4% were men and 29.9% had a low MeDi adherence. Married subjects (adjusted odds ratio ORa=0.68, 95% CI 0.55-0.84 were less likely to have a low MeDi adherence compared to single, divorced or widowed persons. Persons from rural areas (ORa=1.46, 95% CI: 1.02-2.08, were more often low MeDi adherents compared to those from urban areas. Obese persons (ORa=1.56, 95% CI: 1.16-2.11 were more prone to low MeDi adherence than normal weight individuals. Conclusion MeDi is far from being a universal pattern in the Moroccan population. Intervention strategies should be implemented in target groups to maintain the traditional MeDi pattern considered as the original diet in Morocco.

    Full Text Available The Mediterranean-style diet (MedDiet involves substantial intake of fruits, vegetables, and fish, and a lower consumption of dairy, red meat, and sugars. Over the past 15 years much empirical evidence supports the suggestion that a MedDiet may be beneficial with respect to reducing the incidence of cardiovascular disease, cancer, metabolic syndrome, and dementia. A number of cross-sectional studies that have examined the impact of MedDiet on cognition have yielded largely positive results. The objective of this review is to evaluate longitudinal and prospective trials to gain an understanding of how a MedDiet may impact cognitive processes over time. The included studies were aimed at improving cognition or minimizing of cognitive decline. Studies reviewed included assessments of dietary status using either a food frequency questionnaire or a food diary assessment. Eighteen articles meeting our inclusion criteria were subjected to systematic review. These revealed that higher adherence to a MedDiet is associated with slower rates of cognitive decline, reduced conversion to Alzheimer’s disease (AD and improvements in cognitive function. The specific cognitive domains that were found to benefit with improved Mediterranean Diet Score (MedDietS were memory (delayed recognition, long-term and working memory executive function, and visual constructs. The current review has also considered a number of methodological issues in making recommendations for future research. The utilisation of a dietary pattern such as the Mediterranean style diet will be essential as part of the armamentarium to maintain quality of life and reduce the potential social and economic burden of dementia.

    Full Text Available Background: Dietary polyphenols, including phytoestrogens are abundantly present in a balanced diet. Evidence for their role in preventing non-communicable diseases is emerging. Methods: We examined the association between estimated habitual intakes of dietary phytoestrogens and hypertension in a cohort study. The baseline data included 1936 men and women aged 18 years and older. Intakes of total phytoestrogens, isoflavones, and lignans were calculated from validated food frequency questionnaire. Data on the polyphenols content in foods were retrieved from the Phenol-Explorer database. Results: Individuals in the highest quartile of dietary phytoestrogens intake were less likely to be hypertensive (OR: 0.66, 95% CI: 0.44–0.98; moreover, the association showed a significant decreasing trend. Isoflavones and lignans were not associated with lower odds of hypertension; however, some individual compounds, such as biochanin A and pinoresinol showed an independent inverse association with hypertension. Conclusions: Dietary phytoestrogens are associated with lower likelihood of hypertension in adults living in the Mediterranean area. Future studies are needed to confirm the present findings (i.e., prospective cohort studies and to better understand the mechanisms underlying such associations.

    Message framing is a persuasive strategy that has seen mixed evidence for promoting fruit intake intentions, potentially because framed messages for fruit intake have not (a) explicitly compared short-term consequences versus long-term consequences, (b) considered individual-level differences in time perspective, and (c) used alternative measures of fruit intake intentions. In the present online study, the effects of persuasive messages created from temporal context (short term vs. long term) and message frame (gain framed vs. loss framed) were investigated on fruit intake intentions and resolve among a sample of Dutch adults who were categorized as either present oriented or future oriented. For intention and resolve, results showed a significant Type of Frame × Type of Temporal Context interaction, such that gain-framed messages were more persuasive when combined with long-term consequences and loss-framed messages were more persuasive when combined with short-term consequences. The effect sizes for these differences were similar for resolve and intention, but only differences for intentions were significant. No other effects were found. These results demonstrate that message framing theory may usefully consider the inclusion of temporal context of outcomes and alternative motivation measures to maximize their persuasive effects.

    The African populations of Ceratitis capitata (Kenya and Reunion Isl.) and two Mediterranean ones (Sardinia and Procida Isl.) have been studied for genetic variability at 25 loci by electrophoresis. Parameters using gene frequencies indicate the presence of substantial geographic heterogeneity. The major part of this heterogeneity is attributable to genetic drift and is correlated with the dispersion of medfly from the source area of the species (Subsaharan Africa) to the periphery. Kenya has all the properties of a native population, as gene flow estimates, in terms of number of immigrant per generation, is significant between Kenya and the derived Mediterranean populations, supporting the hypothesis of a recent colonization. But part of the geographic heterogeneity is related to the presence of fixed alleles in Reunion population which appears particularly differentiated, although it maintains the genetic attributes of the ancestral population. Selection may have played an important role in the differentiation of this population. 12 refs, 2 figs, 2 tabs

    The elemental composition of four yeast diets differ in protein composition and mixed with sugar as a carbohydrate source were compared with a standard yeast diet used for the mass rearing of med fly C. capitata. The cost availability and the effects on the quality of reared flies were the main measures for these comparisons. Moreover, the elemental composition of reared flies on the tested diets either irradiated to gamma radiation or normal beside full grown pupae (F1) were detected and compared with those reared on standard diet . Data obtained revealed that ten elements (K, N, Na, P, Ca, Fe, Mg, Zn, Mn and Cu) were detected and classified according to their quantities .However those quantities varied according to the type of used yeast ,insect stage , insect sex and irradiated dose. The major group (K, N, Na and P), moderate group (Ca, Fe and Mg) and minor group (Zn, Mn and Cu) remained unchanged although their quantities were changed inside each group. In addition, a significant increase in K, N, Na, P and Ca when diet No.4 (D4) was used to feed flies. These findings may enhance the opportunity of sterile insect technique (SIT). However Fe and Zn ions were decreased with changing the standard yeast and this is may contradict SIT. Also when normal females fed on all tested yeasts, the concentrations of the ten elements increased as compared to those fed on standard diet. These results may increase the efficiency of sterilized reared insects to compete with the native insects in the field

    Objective To explore the antispermatogenic and testicular antisteroidogenic activities of Feronia limonia fruit pulp southern India. Methods Fourty Wistar male albino rats (Rattus norvegicus) were equally divided into four groups. Experimental groups were administered with the ethanolic extract of Feronia limonia (F. limoni) fruit pulp at doses of 250 and 500 mg/kg body weight once daily for 55 days. All treated rats had corresponding recovery groups. At the end of each treatment periods, various spermatological indices, tissue biochemicals and testicular enzymes levels were analysed. Blood profiles were also estimated. Results Compared with the control, the F. limonia fruit pulp at both dose levels did not decrease body weight, which were associated with decline in epididymal sperm count, motility, viability and increased percent of abnormal sperm. Further, F. limonia fruit pulp at 500 mg/kg body weight markedly reduced the epididymal and testicular protein content by 24.58% and 29.86%, respectively, as well as the glucose-6-phosphate dehydrogenase and Δ5-3β-hydroxy steroid dehydrogenase) levels by 42.82% and 38.08%, respectively, while a significant elevation was observed in testicular cholesterol and ascorbic acid content. A gradual recovery of all parameters was observed after 55 days of treatment withdrawal. No significant alterations in haematological indices were observed. Conclusions The present findings indicate that F. limonia fruit pulp may have reversible antispermatogenic and antisteroidogenic properties, and could partially support the traditional use as male contraceptive.

    Fruit, vegetables, cereals, and olive oil are common elements of the Mediterranean diet (MD), but each country in the Mediterranean basin has its own gastronomic customs influenced by socio-cultural, religious, and economic factors. This study compared the dietary habits of three Mediterranean populations with different cultures and lifestyles, a total of 600 adults (61.9% females) between 25 and 70 yrs from Spain, Morocco, and Palestine. All participants completed a self administered questionnaire, including sociodemographic and anthropometric items, a validated semi-quantitative food frequency questionnaire adapted to the foods consumed in each country, and three 24-h recalls. MD adherence was estimated with the MD Serving Score (MDSS). All populations showed a moderate adherence to the Mediterranean dietary pattern. In comparison to the Palestine population, MDSS-assessed adherence to the MD was 6.36-fold higher in the Spanish population and 3.88-fold higher in the Moroccan population. Besides the country of origin, age was another predictive factor of MD adherence, which was greater (higher MDSS) in participants aged over 50 yrs than in those aged 30 yrs or younger. This preliminary study contributes initial data on dietary differences between European and non-European countries in the Mediterranean basin. The Spanish diet was shown to be closer to MD recommendations than the diet of Morocco or Palestine. Given the impact of good dietary habits on the prevention of chronic non-transmittable diseases, health policies should focus on adherence to a healthy diet, supporting traditional dietary patterns in an era of intense commercial pressures for change.

    Full Text Available Spain ranks as the world’s leading exporter of citrus for fresh consumption. Manual harvest accounts for 50% of the total production costs. Mechanical harvest would increase labor productivity and benefits of growers. Efficiency of these machines depends on the varieties and operating conditions. Use of abscission chemicals has been promoted to increase the detachment rate of fruit without affecting its quality. This work is aimed at studying whether the mechanical harvest and/or the application of an abscission agent affect the quality and quantity of harvested fruit and tree defoliation under the conditions of citrus cultivation in Spain. Trials were made in a completely randomized experimental design. From 2008 to 2011, different orchards of mandarin and orange trees were sprayed with different doses of ethephon as abscission agent and harvested with a trunk shaker. Harvest related variables (detachment percentage, defoliation and fruit without calyx were measured. The percentage of fruit detached by the trunk shaker ranged between 70 and 85% and it did not depend on the orchard. The shaker produced minimal damage to the bark when gripped incorrectly. Increased doses of ethephon increased fruit detachment except in ‘Clemenules’ orchard, but also increased the fruit without calyx in 1-9%. Moreover, ethephon promoted significant defoliation. Neither gummosis nor death of branches was observed. This work demonstrates that mechanical harvesting with trunk shakers may be a feasible solution for citrus cultivated in Spain for fresh market. Use of ethephon could only be recommended for citrus destined to industry and only for certain varieties.

    Full Text Available Objectives: To assess prevailing food patterns, and its association with physical activity and fitness among Spanish older adults. Methods: Cross-sectional study in Spain, collecting data from a sample (n = 380; 54% female aged 55–80 years (men and 60–80 years (women with no previously documented cardiovascular disease. Body weight, body fat and waist circumference were assessed. Physical activity performed was measured using the Minnesota Leisure-time Physical Activity Questionnaire (LTPA. Physical fitness was assessed using a validated physical fitness test battery. Food consumption was assessed by a validated semi-quantitative food-frequency questionnaire. Factor analysis identified two major dietary food patterns: “Western” (WDP and “Mediterranean” (MDP dietary patterns. Results: Participants in MDP’s fourth quartile were classified in the second (men and third (men and women tertile of LTPA. After adjusting for age, body fat, waist-to-height ratio, and METs, in both sexes, a negative significant association was found between 30-s Chair stand and 6-min walking test, a positive significant association was found between 30-m Gait speed and 8-foot Time Up-and-Go (except in men tests with WDP. The 30-m Gait speed test was negatively associated with MDP in men. Conclusions: MDP is associated with more time spent on LTPA, and this association was independent of body composition and a fast gait speed in men. WDP is associated with slower gait speed and lower body strength, agility and aerobic endurance. MDP has protective effect on healthy physical fitness, and WDP may be a contributor to frailty.

    Evidence from a limited number of randomised controlled intervention trials (RCTs) have shown that a Mediterranean dietary pattern may reduce the risk of cognitive decline and enhance cognitive function among healthy older adults. However, there are currently no data in non-Mediterranean older adult populations. The present study aimed to address this gap by examining the effect of a Mediterranean dietary pattern (MedDiet) for six months on aspects of cognitive function in a randomised controlled intervention trial (the MedLey study) that extended for a duration of 18 months. In the final analysed cohort, a total of 137 men and women (mean age of 72.1 ± 5.0 years) randomly assigned to either a MedDiet or control diet (HabDiet) (i.e., habitual dietary intake), were assessed on a comprehensive neuropsychological test battery, including 11 individual tests. In multivariable-adjusted models, the MedDiet group did not perform significantly better than the HabDiet control group for executive functioning (adjusted mean differences: +2.53, 95% CI -2.59 to 7.65, p = 0.33); speed of processing (adjusted mean differences: +3.24, 95% CI -1.21 to 7.70, p = 0.15); memory (adjusted mean differences: +2.00, 95% CI -3.88 to 7.88, p = 0.50); visual-spatial ability (adjusted mean differences: +0.21, 95% CI -0.38 to 0.81, 0.48); and overall age-related cognitive performance (adjusted mean differences: +7.99, 95% CI -4.00 to 19.9, p = 0.19). In conclusion, this study did not find evidence of a beneficial effect of a MedDiet intervention on cognitive function among healthy older adults.

    The aim of the present cross-sectional study was to assess the potential relationships between fruit and vegetable (FV) consumption and some oxidative stress markers in young adults, with particular emphasis on fibre and vitamin C intake. The study enrolled 246 healthy subjects (eighty-eight men and 158 women), with a mean age of 22 (sd 3) years and a mean BMI of 21·9 (sd 2·8) kg/m2. Dietary intake, anthropometry, blood pressure, lifestyle features and blood biochemical data were assessed with validated procedures. Those subjects in the highest tertile (T) of FV consumption ( ≥ 705 g/d) had statistically lower oxidised LDL (ox-LDL) concentrations as well as higher plasma total antioxidant capacity (TAC) and glutathione peroxidase (GPx) activity (P for trend well as increased TAC and GPx activity in healthy young adults, with dietary fibre and vitamin C from FV clearly being implicated in this beneficial relationship.

    Osteoporosis is a major health problem that will grow in burden with ageing of the global population. Modifiable risk factors for osteoporosis, including diet, have significant implications for disease prevention. We examined associations between dietary patterns and bone mineral density (BMD) in a Korean adult population. In total, 1828 individuals from the Healthy Twin Cohort were included as subjects. Information on general characteristics, lifestyles and health status was obtained through a health examination, and BMD was assessed using DEXA. Dietary intake was assessed using a 3-day food record, and dietary patterns were examined by factor analysis. Associations between dietary patterns and BMD were examined using mixed linear regression, adjusting for family and twin structure as well as other potential risk factors for bone health. Four dietary patterns were identified (Rice and kimchi; eggs, meat and flour; Fruit, milk and whole grains; and Fast food and soda). The 'Fruit, milk and whole grains' pattern was associated with a reduced risk of having low BMD in men (odds ratio (OR)=0.38; 95% confidence interval (CI)=0.22-0.67) and women (OR=0.45; 95% CI=0.28-0.72) and was positively associated with BMD at multiple sites. The 'rice and kimchi' pattern had a positive association with only whole-arm BMD in men and women. Our results suggest that a dietary pattern with high intake of dairy products, fruits and whole grains may contribute positively to bone health in a Korean adult population, and dietary pattern-based strategies could have potential in promoting bone health.

    Food insecurity is a limited or uncertain access to the adequate food and is a significant public health problem. We aimed to assess determinants of food insecurity and the corresponding health impact in Portugal, a southern European country that faced a severe economic crisis. Data were derived from the Epidemiology of Chronic Diseases Cohort Study (EpiDoC), a population-based cohort of 10,661 individuals that were representative of the Portuguese adult population and followed since 2011. A cross-sectional analysis of the third wave of evaluation (EpiDoC 3) was performed between 2015 and 2016. Food insecurity was assessed with the household food insecurity psychometric scale. Socioeconomic, demographic, lifestyle, adherence to Mediterranean diet (MD), self-reported non-communicable disease, health-related quality of life (HRQoL) (EQ-5D-3L), physical function (HAQ score), and health resource consumption information was also collected. The estimated proportion of food insecurity was 19.3% among a total of 5,653 participants. Food insecure households had low adherence to the MD (OR = 0.44; 95% IC 0.31-0.62). In addition, diabetes (OR = 1.69; 95% IC 1.20-2.40), rheumatic disease (OR = 1.67; 95% IC 1.07-2.60), and depression symptoms (OR = 1.50; 95% IC 1.09-2.06) were independently associated with food insecurity. On average, food insecure households had a lower HRQoL (OR = 0.18; 95% IC 0.11-0.31) and a higher disability (OR = 2.59; 95% IC 2.04-3.29). A significantly higher proportion of food insecure households reported being hospitalized (OR = 1.57; 95% IC 1.18-2.07) and had more public hospital medical appointments (OR = 1.48; 95% IC 1.12-1.94) in the previous 12 months. We found that food insecurity is highly prevalent in Portugal. Food insecurity was associated with low adherence to the MD, non-communicable chronic diseases, lower quality of life, and higher health resource consumption. Therefore, this study provides valuable

    Full Text Available Abstract Background Accumulating evidence suggests that fruit and vegetable intake (FVI plays a protective role against major diseases. Despite this protective role and the obesity pandemic context, populations in Western countries usually eat far less than five servings of fruits and vegetables per day. In order to increase the efficiency of interventions, they should be tailored to the most important determinants or mediators of FVI. The objective was to systematically review social cognitive theory-based studies of FVI and to identify its main psychosocial determinants. Methods Published papers were systematically sought using Current Contents (2007-2009 and Medline, Embase, PsycINFO, Proquest and Thesis, as well as Cinhal (1980-2009. Additional studies were identified by a manual search in the bibliographies. Search terms included fruit, vegetable, behaviour, intention, as well as names of specific theories. Only studies predicting FVI or intention to eat fruits and vegetables in the general population and using a social cognitive theory were included. Independent extraction of information was carried out by two persons using predefined data fields, including study quality criteria. Results A total of 23 studies were identified and included, 15 studying only the determinants of FVI, seven studying the determinants of FVI and intention and one studying only the determinants of intention. All pooled analyses were based on random-effects models. The random-effect R2 observed for the prediction of FVI was 0.23 and it was 0.34 for the prediction of intention. Multicomponent theoretical frameworks and the theory of planned behaviour (TPB were most often used. A number of methodological moderators influenced the efficacy of prediction of FVI. The most consistent variables predicting behaviour were habit, motivation and goals, beliefs about capabilities, knowledge and taste; those explaining intention were beliefs about capabilities, beliefs about

    The operational use of Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann), genetic sexing strains in Sterile Insect Technique applications can be maximized by developing methods for effective shipment of eggs. This would enable a central production facility to maintain the relevant mother stocks and large colonies to supply eggs to satellite centers that would mass produce only males for irradiation and release. In order to achieve this, the survival of medfly embryos of different ages was assessed after storage at 5, 10, 15, 20, and 25 deg. C in water for different periods of time. Survival was affected by all 3 variables, i.e., embryo age, water temperature, and length of storage. Storage of embryos at any temperature for 120 h resulted in almost no survival. Controlling the age of the embryo at the time of the temperature treatment is crucial for the success of this procedure. Embryos collected between 0 to 12 h after oviposition and pre-incubated at 25 deg. C for 12 h provide a suitable 72 h window for shipment when maintained between 10 to 15 deg. C. Under these conditions, no significant reductions in survival during all the developmental stages were observed. (author) [es

    Background: Poor diet quality is associated with a higher risk of many chronic diseases that are among the leading causes of death in the United States. It has been hypothesized that evolutionary discordance may account for some of the higher incidence and mortality from these diseases. Objective: We investigated associations of 2 diet pattern scores, the Paleolithic and the Mediterranean, with all-cause and cause-specific mortality in the REGARDS (REasons for Geographic and Racial Differences in Stroke) study, a longitudinal cohort of black and white men and women ≥45 y of age. Methods: Participants completed questionnaires, including a Block food-frequency questionnaire (FFQ), at baseline and were contacted every 6 mo to determine their health status. Of the analytic cohort ( n = 21,423), a total of 2513 participants died during a median follow-up of 6.25 y. We created diet scores from FFQ responses and assessed their associations with mortality using multivariable Cox proportional hazards regression models adjusting for major risk factors. Results: For those in the highest relative to the lowest quintiles of the Paleolithic and Mediterranean diet scores, the multivariable adjusted HRs for all-cause mortality were, respectively, 0.77 (95% CI: 0.67, 0.89; P- trend diets closer to Paleolithic or Mediterranean diet patterns may be inversely associated with all-cause and cause-specific mortality. © 2017 American Society for Nutrition.

    Biological studies were conducted to determine the effect of boric acid applied alone to different stages of ceratitis capitata or combined with gamma radiation of the produced treated pupae (9 days old). At a concentration range of 200-2000 ppm of boric acid per gm larval diet, larval and pupal durations were insignificantly affected. Pupation significantly decreased with increasing concentration, and adult emergence significantly increased at higher concentrations. Lc50 value of boric acid applied to the larval diet was 250 ppm. Applying boric acid as a powder mixed with pupal medium, the Lc50 was 96 mg/gm sand. Male and emergence significantly decreased. Significant mortality was obtained in adults of C capitata after applying boric acid as a thin film on the inner surface of the experimental cages where the adults were kept or when mixed with their food or as powder on the cage bottom. Applying boric acid to larval diet and gamma radiation to the produced pupae (9 days old) insignificantly affected larval and durations, percent pupation, adult emergence or adult survival. In cross-mating experiments, egg hatch ability was significantly reduced in the combination treatments of boric acid (500, 1000 ppm) and gamma radiation (90 Gy). On the other hand gamma radiation combined with boric acid treatments significantly increased male mating competitiveness at the concentration of 1000 ppm of boric acid followed by gamma irradiation (90 Gy). 2 figs., 5 tabs

    The presence of pesticide residues in fruit is a serious health concern. This paper for the first time demonstrated the Hazard Index (HI) method to carry out acute, chronic and cumulative health risk assessment to the 14 groups of insecticides for three subpopulations. The challenge of this study was to present results from a long period of research (years 2005–2014) with toxicological aspects, especially in multiresidue samples. Near 1000 fresh pome, stone, berries and small fruit were prepared by two accredited MSPD and QuEChERS methods followed by liquid and gas chromatography analyses with various systems of detection ECD/NPD/MS/MS. Twenty percent of the fruit samples contained 16 insecticide residues in the range of 0.01–0.81 mg/kg and 3% over MRL. The class of pesticide with the highest contribution to the ADI was found to be OPPs: dimethoate and diazinon for adults 48% and 66% of the ADI whereas for infants 144% and 294% of the ADI. The highest contributions of the cHQ to common MoA pesticides were AChE inhibitors: 135% for adults and 528% for infants, sodium channel modulators 4.9% and 20%, nicotic acetylocholine receptor < 2.9% and < 10.6% for adults and infants, respectively. The fruit with the highest contribution to the ADI were found to be apples (316%, 58%), cherries (96%, 37%) and pears (129%, 33%) for infants and adults. The study findings indicated that dietary exposures to insecticide residues in fruit would be unlikely to pose unacceptable health risks for the infants, toddlers and adults. - Highlights: • Health risk assessment of insecticide via dietary intake of fruit was estimated. • Sixteen residues in pome, stone, berries and small fruit ranged from 0.01 to 0.8 mg/kg. • Organophosphates were the most frequently occurring group with common MoA. • Dietary exposures for adults and children were below the safety reference values. • Toxicological study provided important date of human health.

    This paper examines fruit and vegetable intake (FVI) in low-income households that participated in a cost-offset (CO), or 50% subsidized, community-supported agriculture (CSA) program. CSA customers paid farms upfront for a share of the harvest, and received produce weekly throughout the growing season. A cohort of adults and children 2-12 y in a summer CO-CSA were surveyed online twice: August 2015 ( n = 41) and February 2016 ( n = 23). FVI was measured by the National Cancer Institute's (NCI) Fruit and Vegetable Screener (FVS) and an inventory of locally grown fruits and vegetables. FVI relative to United States (US) recommendations and averages, and across seasons, were tested with non-parametric tests and paired t -tests ( p < 0.05). Both adults and children in the CO-CSA had higher FVI than the US averages, and more often met recommendations for vegetables. Some summer fruits and vegetables were more often eaten when locally in-season. The CO-CSA model warrants further examination as an avenue for improving vegetable consumption among adults and children in low-income households. However, causality between CO-CSA participation and FVI cannot be inferred, as CO-CSA participants may be positive deviants with respect to FVI. A multi-state randomized controlled trial is currently underway to evaluate impacts of CO-CSAs on FVI and related outcomes.

    Anemia is the most widely prevalent form of micronutrient deficiency that affects over a quarter of the global population. Evidence suggests that the burden of anemia is higher in the developing countries with women of reproductive age and children being the most at-risk groups. The most common causes are believed to be malnutrition and low bioavailability of micronutrients, which usually result from poor dietary habits and inadequate intake of food rich in micronutrients such as fresh fruits and vegetables. Regular consumption of F&V was shown to have protective effect against NCDs; however, evidence on this protective effect against micronutrient deficiency diseases are limited. (1) To measure the prevalence of anemia among adult non-pregnant women in Ghana, and (2) to investigate if there is any cross-sectional relationship between F&V consumption and anemia. This is a cross-sectional study based on data extracted from the Ghana Demographic and Health Survey, 2008. Subjects were 4,290 non-pregnant women aged between 15 and 49 years. Hemoglobin levels were measured by HemoCue ® hemoglobin-meter. Association between anemia and F&V consumption was assessed by multivariable regression methods. Findings indicate that well over half (57.9%) of the women were suffering from anemia of some level. The percentage of women consuming at least five servings of fruits and vegetables a day were 5.4% and 2.5% respectively. Results of multivariable analysis indicated that among urban women, consumption of 5 servings/day. The findings indicate that urban women who did not maintain WHO recommended level of F&V consumption bear a significantly higher likelihood of being moderate to severely anemic.

    Chronic inflammation and oxidative balance are associated with poor diet quality and risk of cancer and other chronic diseases. A diet-inflammation/oxidative balance association may relate to evolutionary discordance. We investigated associations between 2 diet pattern scores, the Paleolithic and the Mediterranean, and circulating concentrations of 2 related biomarkers, high-sensitivity C-reactive protein (hsCRP), an acute inflammatory protein, and F2-isoprostane, a reliable marker of in vivo lipid peroxidation. In a pooled cross-sectional study of 30- to 74-y-old men and women in an elective outpatient colonoscopy population (n = 646), we created diet scores from responses on Willett food-frequency questionnaires and measured plasma hsCRP and F2-isoprostane concentrations by ELISA and gas chromatography-mass spectrometry, respectively. Both diet scores were calculated and categorized into quintiles, and their associations with biomarker concentrations were estimated with the use of general linear models to calculate and compare adjusted geometric means, and via unconditional ordinal logistic regression. There were statistically significant trends for decreasing geometric mean plasma hsCRP and F2-isoprostane concentrations with increasing quintiles of the Paleolithic and Mediterranean diet scores. The multivariable-adjusted ORs comparing those in the highest with those in the lowest quintiles of the Paleolithic and Mediterranean diet scores were 0.61 (95% CI: 0.36, 1.05; P-trend = 0.06) and 0.71 (95% CI: 0.42, 1.20; P-trend = 0.01), respectively, for a higher hsCRP concentration, and 0.51 (95% CI: 0.27, 0.95; P-trend 0.01) and 0.39 (95% CI: 0.21, 0.73; P-trend = 0.01), respectively, for a higher F2-isoprostane concentration. These findings suggest that diets that are more Paleolithic- or Mediterranean-like may be associated with lower levels of systemic inflammation and oxidative stress in humans. © 2016 American Society for Nutrition.

    Non-alcoholic fatty liver disease, the most prevalent liver disease in developed countries, remains difficult to manage with no proven safe and effective pharmacotherapy available. While weight reduction is the most commonly practiced treatment strategy, this is difficult to both achieve and/or maintain in the majority. Furthermore evidence-based dietary recommendations to guide the nutritional management of these patients are lacking. Using a randomised controlled trial design, this study compares the effectiveness of the Mediterranean diet to a standard low fat diet in terms of differences in insulin sensitivity, hepatic steatosis and metabolic outcomes in participants with non-alcoholic fatty liver disease. Ninety four eligible patients who have non-alcoholic fatty liver disease and who are insulin resistant, will be randomised into either a Mediterranean or low fat diet group for a 3 month intervention period. Insulin sensitivity will be measured on peripheral blood using Homeostatic Model Assessment and liver fat content quantified using Magnetic Resonance Spectroscopy. Both arms will consist of three face to face and three telephone call follow up consultations delivered by an Accredited Practicing Dietitian. The intervention arm focuses on recommendations from the traditional Mediterranean diet which have been tailored for use in the Australian population The standard arm uses the Australian Guide to Healthy Eating and the Australian National Heart Foundation dietary guidelines. Study recruitment will take place at four major metropolitan hospitals in Melbourne, Australia. Data collection will occur at all face to face reviews including baseline, 6, and 12 weeks. A follow up assessment to measure sustainability will take place at 6 and 12 months. The primary end point is improved insulin sensitivity scores at the 12 week time point. This trial aims to demonstrate in a large cohort of participants with NALFD that a Mediterranean diet independent of weight

    dietary modification can potentially reduce dementia risk, but the importance of fruits and the amount of vegetables and fruits required for cognitive maintenance are uncertain. We examined whether the minimal daily requirement of vegetables and fruits recommended by the World Health Organization (WHO) would independently lower dementia risk. in this population-based observational study, we examined the diet of 17,700 community-living dementia-free Chinese older adults who attended the Elderly Health Centres in Hong Kong at baseline and followed their cognitive status for 6 years. In line with the WHO recommendation, we defined the cutoff for minimal intake of vegetables and fruits as at least three and two servings per day, respectively. The study outcome was incident dementia in 6 years. Dementia was defined by presence of clinical dementia in accordance with the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10) or Clinical Dementia Rating of 1-3. multivariable logistic regression analysis showed that the estimated odds ratios for incident dementia were 0.88 (95% confidence interval 0.73-1.06; P = 0.17) for those consuming at least three servings of vegetables per day, 0.86 (0.74-0.99; P dementia in older adults. © The Author 2017.

    Full Text Available This study was aimed to assess the protective effects of Cornus mas fruit extract (CMFE and vitamin E (Vit E on sperm quality parameters in the methotrexate (MTX-treated mice. Forty-eight young adult male mice (8-12 weeks were randomly divided into six groups including control and test groups. The control group received normal saline orally , and the test groups were treated MTX (20 mg kg-1, ip, once weekly, MTX + CMFE (250 mg kg-1, MTX + CMFE (500 mg kg-1, MTX + CMFE (1000 mg kg-1, and MTX + Vit E (100 IU kg-1, po for 35 consecutive days. On day 35, after euthanasia the epididymal sperms were isolated. Then the total mean sperm count, sperm viability and motility were determined. The total antioxidant capacity (TAOC of all experimental groups were also evaluated. The MTX-treated animals showed a significant changes in all parameters of sperm quality assessment compared to the control group. Both Vit E and CMFE were able to protect from MTX-induced effects on sperm maturity and DNA damage. Co-administration of MTX and CMFE and/or Vit E resulted in protection from MTX-reduced TAOC. In conclusion, these data suggested that MTX administration could adversely affect the sperm quality. Moreover, the protective effect of Vit E and CMFE on MTX-induced sperm toxicity was also documented.

    This study aimed to evaluate the protective effect of sodium selenite (SS) at different concentrations (10 - 6 ; 5×10 - 6 ; 10 - 5 ; 5×10 - 5 ; 10 - 4 M) added to larval diet of irradiated Ceratitis capitata on some biological and biochemical parameters. The resulting pupae were exposed to the sterilizing dose of gamma irradiation (90Gy).The percent of adult emergence showed a significant decrease with low concentrations. A significant decrease was in the percent of hatch ability at 90Gy alone or combined with different SS concentrations. The combined effect of SS with the concentrations (10 - 4 ; 5×10 - 5 ; 10 - 5 ) and gamma irradiation significantly decreased the number of eggs laid daily after mating with SS treated males, while the concentration 10 - 4 increased the number of eggs laid daily after mating normal males with SS treated females. The combined effect of SS with gamma irradiation showed an increase in total protein and total carbohydrate levels while total lipid levels decreased significantly in irradiated pupae. A significant increase was observed in total carbohydrates at concentrations 5×10 - 6 ,10 - 5 , 5×10 - 5 and 10 - 4 M of SS. However, the combined effect of 10 - 6 SS with gamma irradiation showed a significant decrease in total carbohydrate levels compared to irradiated pupae. The glucose levels were significantly increased at the concentrations 5×10 - 6 , 10 - 5 , 5×10 - 5, 10 - 4 M of SS combined with the sterilizing dose. Generally, the combined treatment of selenium and gamma irradiation could be used successfully in order to improve performance of the irradiated adults and could subsequently be applied in the integrated pest management program (IPM) to help in the success of the sterile insect technique (SIT) of med fly

    Both systemic redox status and diet quality are associated with risk outcomes in chronic disease. It is not known, however, the extent to which diet quality influences plasma thiol/disulfide redox status. The purpose of this study was to investigate the influence of diet, as measured by diet quality scores and other dietary factors, on systemic thiol/disulfide redox status. We performed a cross-sectional study of 685 working men and women (ages ≥18 y) in Atlanta, GA. Diet was assessed by 3 diet quality scores: the Alternative Healthy Eating Index (AHEI), Dietary Approaches to Stop Hypertension (DASH), and the Mediterranean Diet Score (MDS). We measured concentrations of plasma glutathione (GSH), cysteine, their associated oxidized forms [glutathione disulfide (GSSG) and cystine (CySS), respectively], and their redox potentials (EhGSSG and EhCySS) to determine thiol/disulfide redox status. Linear regression modeling was performed to assess relations between diet and plasma redox after adjustment for age, body mass index (BMI), sex, race, and history of chronic disease. MDS was positively associated with plasma GSH (β = 0.02; 95% CI: 0.003, 0.03) and total GSH (GSH + GSSG) (β = 0.02; 95% CI: 0.003, 0.03), and inversely associated with the CySS:GSH ratio (β = -0.02; 95% CI: -0.04, -0.004). There were significant independent associations between individual MDS components (dairy, vegetables, fish, and monounsaturated fat intake) and varying plasma redox indexes (P indexes and other diet factors of interest were not significantly correlated with plasma thiol and disulfide redox measures. Adherence to the Mediterranean diet was significantly associated with a favorable plasma thiol/disulfide redox profile, independent of BMI, in a generally healthy working adult population. Although longitudinal studies are warranted, these findings contribute to the feasibility of targeting a Mediterranean diet to improve plasma redox status.

    Full Text Available Background. Information about iodine intake is crucial for preventing thyroid diseases. Inadequate iodine intake can lead to thyroid diseases, including nontoxic nodular goiter (NNG. Objective. To estimate iodine intake and explore its correlation with thyroid diseases among Israeli adults living near the Mediterranean coast, where iodine-depleted desalinated water has become a major source of drinking water. Methods. Cross-sectional study of patients attending Barzilai Medical Center Ashkelon. Participants, who were classified as either NNG (n=17, hypothyroidism (n=14, or control (n=31, provided serum thyroglobulin (Tg and completed a semiquantitative iodine food frequency questionnaire. Results. Elevated serum Tg values (Tg > 60 ng/mL were significantly more prevalent in the NNG group than in the other groups (29% versus 7% and 0% for hypothyroidism and controls, resp., P<0.05. Mean estimated iodine intake was significantly lower in the NNG group (65±30 μg/d than in controls (115±60 μg/d (P<0.05 with intermediate intake in the hypothyroid group (73±38 μg/d. Conclusions. Elevated serum Tg values and low dietary iodine intake are associated with NNG among adult patients in Ashkelon District, Israel. Larger studies are needed in order to expand on these important initial findings.

    Identify underlying salient behavioral, normative, and control beliefs about fruit and vegetable (F&V) consumption among limited-income older adults. The Theory of Planned Behavior (TPB) was used as the framework for conducting semistructured individual interviews in 2016. Two congregate meal sites in the city of Tuscaloosa, AL. A total of 25 low-income older adults aged ≥60 years. Behavioral, normative, and control beliefs about F&V intake. All interviews were audiotaped and transcribed verbatim. Data were analyzed using a hybrid inductive and deductive content analysis approach. The elicitation interviews identified salient behavioral, normative, and control beliefs about F&V intake among low-income older adults. These results can be used to develop nutrition education programs aimed at improving economically vulnerable older adults' F&V intake. Copyright © 2017 Society for Nutrition Education and Behavior.

    The Seven Countries study in the 1960s showed that populations in the Mediterranean region experienced lower cardiovascular disease (CVD) mortality probably as a result of different dietary patterns. Later observational studies have confirmed the benefits of adherence to a Mediterranean dietary pattern on CVD risk factors. Clinical trial evidence is limited, and is mostly in secondary prevention. To determine the effectiveness of a Mediterranean dietary pattern for the primary prevention of CVD. We searched the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 9 of 12, September 2012); MEDLINE (Ovid, 1946 to October week 1 2012); EMBASE (Ovid, 1980 to 2012 week 41); ISI Web of Science (1970 to 16 October 2012); Database of Abstracts of Reviews of Effects (DARE), Health Technology Assessment Database and Health Economics Evaluations Database (Issue 3 of 12, September 2012). We searched trial registers and reference lists of reviews and applied no language restrictions. We selected randomised controlled trials in healthy adults and adults at high risk of CVD. A Mediterranean dietary pattern was defined as comprising at least two of the following components: (1) high monounsaturated/saturated fat ratio, (2) low to moderate red wine consumption, (3) high consumption of legumes, (4) high consumption of grains and cereals, (5) high consumption of fruits and vegetables, (6) low consumption of meat and meat products and increased consumption of fish, and (7) moderate consumption of milk and dairy products. The comparison group received either no intervention or minimal intervention. Outcomes included clinical events and CVD risk factors. Two review authors independently extracted data and contacted chief investigators to request additional relevant information. We included 11 trials (15 papers) (52,044 participants randomised). Trials were heterogeneous in the participants recruited, in the number of dietary components and

    We aimed to investigate the associations of colors of fruit and vegetable (FV) subgroups, with 3-year changes of cardiometabolic risk factors. This longitudinal study was conducted in the framework of Tehran Lipid and Glucose Study, between 2006-2008 and 2009-2011, on 1272 adults. Total intake of FV and their subgroups have been assessed by a validated semi-quantitative food frequency questionnaire at baseline (2006-2008) and again at the second examination (2009-2011). Demographics, anthropometrics and biochemical measures were evaluated at baseline and 3 years later. The associations of anthropometric and lipid profile changes with FV subgroups were estimated. The mean age of men and women at baseline was 39.8±12.7 and 37.3±12.1 years, respectively. Mean total intake of FV, red/purple, yellow, green, orange and white FV was 706±337, 185±95, 141±91, 152±77, 141±87 and 22±18 g/day, respectively. In men, 3-year changes of weight (β=-0.13, P=0.01) and waist circumference (β=-0.14, P=0.01) were related to intake of red/purple FV; the yellow group was inversely associated with 3-year changes of total cholesterol (β=-0.09, P=0.03) and High-density lipoprotein cholesterol (β=-0.11, P=0.03). Consumption of green and white FV was inversely related to abdominal fat gain, and atherogenic lipid parameters in men (Pfasting serum glucose and total cholesterol (P<0.05); yellow FV was also related to 3-year weight gain (β=-0.11, P=0.01). Various colors of FV subgroups had different effects on cardiometabolic risk factors; higher intake of red/purple FV may be related to lower weight and abdominal fat gain, and yellow, green and white FV may be related to lipid parameters.

    To assess adherence to the Mediterranean diet and nutrient intakes in a population of Sicily, southern Italy and to evaluate possible determinants, particularly socio-cultural and lifestyle factors. Cross-sectional. Urban and rural areas of eastern Sicily. Between May 2009 and December 2010, 3090 adults were randomly recruited through the collaboration of fourteen general practitioners. Adherence to the Mediterranean diet was measured by the MedDietScore. Nutrient intakes were assessed through the 24 h recall of the previous day's dietary intake. Rural participants were barely more adherent to the Mediterranean diet than their urban counterparts (mean scores were 27·8 and 27·2, respectively, P = 0·037). The MedDietScore was correlated with intakes of MUFA, fibre and vitamin C, as well as with consumption of non-refined cereals, vegetables, fruit, meat, dairy products, alcohol and nuts. Regression analysis revealed that older and more educated people were more likely to be in the highest tertile of MedDietScore (OR = 1.90; 95 % CI 1·39, 2·59 and OR = 1·29; 95 % CI 1·05, 1·58, respectively). A significant difference in quantity (moderate) and quality (red wine and beer) of alcohol was found according to adherence to the Mediterranean diet. Finally, more active participants were 1·5 times more likely to form part of the high-adherence group. A slow but concrete moving away from traditional patterns has been observed in younger people and low educated people. Public health interventions should focus on these target populations in order to improve the quality of their diet.

    Since 1954, when the first tropical tephritid fruit fly was detected in California, a total of 17 species in four genera and 11 386 individuals (adults/larvae) have been detected in the state at more than 3348 locations in 330 cities. We conclude from spatial mapping analyses of historical capture patterns and modelling that, despite the 250+ emergency eradication projects that have been directed against these pests by state and federal agencies, a minimum of five and as many as nine or more tephritid species are established and widespread, including the Mediterranean, Mexican and oriental fruit flies, and possibly the peach, guava and melon fruit flies. We outline and discuss the evidence for our conclusions, with particular attention to the incremental, chronic and insidious nature of the invasion, which involves ultra-small, barely detectable populations. We finish by considering the implications of our results for invasion biology and for science-based invasion policy.

    Full Text Available This study estimated indicators of fruit and vegetable intake by Brazilian adults and examined the influence of demographic and socioeconomic variables on the consumption of these foods. We used the following indicators: daily fruit intake, daily vegetable intake, and daily consumption of five or more servings of fruits and vegetables per day. Only 41.0% of adults reported daily fruit intake, while 30.0% reported daily vegetable intake. Fruit and vegetable intake was more common in urban as compared to rural areas and increased in both genders with age, schooling, and number of household goods. We conclude that initiatives to promote fruit and vegetable consumption are necessary for the country as a whole, but special attention should be given to younger individuals, males, rural communities, and groups with less schooling and lower income.O presente estudo estimou a freqüência e a distribuição do consumo de frutas e hortaliças e analisou a influência de variáveis demográficas e sócio-econômicas na determinação do padrão de consumo desses alimentos na população adulta do Brasil. Os indicadores do consumo alimentar foram: consumo diário de frutas, de hortaliças, consumo diário de frutas e hortaliças e consumo diário de cinco ou mais porções de frutas e hortaliças. Menos da metade (41,0% dos indivíduos adultos refere o consumo diário de frutas enquanto menos de um terço (30,0% refere o consumo diário de hortaliças. O consumo de frutas e hortaliças é maior nas áreas urbanas do que nas áreas rurais e aumenta com a idade e escolaridade dos indivíduos, e com o número de bens no domicílio, em ambos os sexos. Concluímos que iniciativas de promoção do consumo de frutas e hortaliças devem atender a população como um todo, mas que especial atenção deve ser dada a indivíduos jovens, ao sexo masculino, a áreas rurais e aos estratos populacionais com insuficiente escolaridade e baixa renda.

    To determine the prevalence of anxiety and depression among patients with familial Mediterranean fever (FMF) living in Germany or Turkey a prospective study was conducted. Forty FMF patients living in Turkey (T), 40 FMF patients living in Germany (G) and 40 healthy controls living in Germany (C) were included. Patients and controls were of Turkish ancestry. G were compared to T and C. The Hospital Anxiety and Depression Scale (HADS) was used with a cut-off of ≥ 8 for each subdomain score (HADS-A, HADS-D). Baseline characteristics of G were comparable to T and C except for age (T: 30.5 years, G: 35.2 years, C: 34.6 years; T vs. G P = 0.045), duration of disease (T: 14.4 years, G: 24; P < 0.001), C-reactive protein (T: 0.78 mg/dL, G: 0.78 mg/dL, C: 0.35 mg/dL; G vs. C P = 0.03). Prevalence of anxiety was higher in G compared to C (T: 65%, G: 52.5%, C: 22.5%: G vs. C P < 0.05). No difference was found for the prevalence of depression (T: 30%, G: 35%, C: 20%). The association between FMF and anxiety in subjects living in Germany persisted after adjusting for age and gender in a regression analysis and was robust to an adjustment for coexisting depression. Anxiety and depression did not correlate with FMF disease severity assessed with the Pras score. Anxiety, but not depression is more common among FMF patients living in Germany compared to healthy controls. No significant difference could be found between FMF patients living in Germany or Turkey concerning the prevalence of anxiety or depression. © 2014 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

  5. PON1 and Mediterranean Diet

    Full Text Available The Mediterranean diet has been proven to be highly effective in the prevention of cardiovascular diseases. Paraoxonase 1 (PON1 has been implicated in the development of those conditions, especially atherosclerosis. The present work describes a systematic review of current evidence supporting the influence of Mediterranean diet and its constituents on this enzyme. Despite the differential response of some genetic polymorphisms, the Mediterranean diet has been shown to exert a protective action on this enzyme. Extra virgin olive oil, the main source of fat, has been particularly effective in increasing PON1 activity, an action that could be due to low saturated fatty acid intake, oleic acid enrichment of phospholipids present in high-density lipoproteins that favor the activity, and increasing hepatic PON1 mRNA and protein expressions induced by minor components present in this oil. Other Mediterranean diet constituents, such as nuts, fruits and vegetables, have been effective in modulating the activity of the enzyme, pomegranate and its compounds being the best characterized items. Ongoing research on compounds isolated from all these natural products, mainly phenolic compounds and carotenoids, indicates that some of them are particularly effective, and this may enhance the use of nutraceuticals and functional foods capable of potentiating PON1 activity.

    The aims of the present work were to determine the frequency and distribution of caries and tooth wear on paired maxillae of a mediaeval sample from southwest France in which the sex of the remains had been established, and to make a relation with the diet of this population. The sample analysed consisted of the dental remains of 58 adult individuals (29 men and 29 women) excavated from the mediaeval cemetery of the archaeological site of Vilarnau d'Amont (southwest France). A total of 1395 teeth were examined. The frequency of ante-mortem tooth loss for the sample was 8.7% and the frequency of caries was 17.5%. The frequencies of carious lesions in adult men and women's dentition were 21.9% and 14.0%. The most frequent were occlusal (49.7% and 34.3%) and approximal caries (26.5% and 37.4%). Concerning tooth wear, all 58 individuals were affected by attrition (100%) and more than 90% of the teeth were concerned. Most of them showed the presence of dentin clusters. There was no significant difference between men and women for caries and tooth wear. These findings are similar to those of other studies on European populations of the same socio-economic status and confirm the predominance of tooth wear over carious lesions during this period. Both caries and tooth wear may be related to the regional diet of this rural population.

    Beyond quantity, variety of fruit and vegetable (FV) intake prevents chronic conditions and is widely recommended as critical to healthful eating. FV consumption is socially patterned, especially for women, but little is known about multiple economic determinants of variety or whether they differ from those of quantity. To examine socioeconomic status and financial hardships in relation to variety and quantity of FV intakes among older British women and men. Cross-sectional study of 9580 adults (50-79 years) in the nationally representative EPIC cohort who responded to a postal Health and Life Experiences Questionnaire (1996-2000) and Food Frequency Questionnaire (1998-2002). Variety counted unique items consumed (items/month) and quantity measured total intake (g/day). No consistent differences by any economic factor were observed for quantity of fruits or vegetables, except education in men. Lower education, lower social class and renting were independently associated with lower fruit variety and vegetable variety (p-trend consumption of diverse FV. Copyright © 2014 The Authors.

    Consuming fruit and vegetables (FVs) may protect against frailty, but to our knowledge no study has yet assessed their prospective dose-response relation. We sought to examine the dose-response association between FV consumption and the risk of frailty in older adults. Data were taken from 3 independent cohorts of community-dwelling older adults: the Seniors-ENRICA (Study on Nutrition and Cardiovascular Risk Factors in Spain) cohort (n = 1872), Three-City (3C) Bordeaux cohort (n = 581), and integrated multidisciplinary approach cohort (n = 473). Baseline food consumption was assessed with a validated computerized diet history (Seniors-ENRICA) or with a food-frequency questionnaire (3C Bordeaux and AMI). In all cohorts, incident frailty was assessed with the use of the Fried criteria. Results across cohorts were pooled with the use of a random-effects model. During a mean 2.5-y follow-up, 300 incident frailty cases occurred. Fully adjusted models showed that the pooled ORs (95% CIs) of incident frailty comparing participants who consumed 1, 2, or ≥3 portions of fruit/d to those with no consumption were, respectively, 0.59 (0.27, 0.90), 0.58 (0.29, 0.86), and 0.48 (0.20, 0.75), with a P-trend of 0.04. The corresponding values for vegetables were 0.69 (0.42, 0.97), 0.56 (0.35, 0.77), and 0.52 (0.13, 0.92), with a P-trend consumption of fruit and risk of exhaustion, low physical activity, and slow walking speed, whereas the consumption of vegetables was associated with a decreased risk of exhaustion and unintentional weight loss. Among community-dwelling older adults, FV consumption was associated with a lower short-term risk of frailty in a dose-response manner, and the strongest association was obtained with 3 portions of fruit/d and 2 portions of vegetables/d. © 2016 American Society for Nutrition.

    Objective To assess the prevalence and risk factors of overweight (OW) and obesity (OB) by BMI and abdominal obesity (AO) by waist-to-height ratio, (WHtR) among the Balearic Islands' adult population. Methods Cross-sectional nutritional survey carried out in the Balearic Islands (2009-2010). A random sample (n = 1,081) of young (18-35 years) and middle-aged adults (36-55 years) were interviewed and anthropometrically measured. OW (BMI 25.0-29.9 kg/m2) and OB (BMI ≥ 30 kg/m2) were defined according to WHO criteria. AO was defined as WHtR ≥ 0.5. Socio-economic and lifestyle determinants were considered. Results The overall prevalence of OW/OB and AO was 29.4% (95% confidence interval (95% CI) 26.9-32.3%), 11.2% (95% CI 9.5-13.2%) and 33.1% (95% CI 30.4-36.0%), respectively. Men showed higher prevalence of OW (35.9%, 95% CI 31.6-40.5%) and AO (37.9%, 95% CI 33.6-42.5%) than women (OW 24.9%, 95% CI 21.7-28.4%; AO 29.7%, 95%CI 26.2-33.4%). Overall prevalence of OB was 11.8% (95% CI 9.1-15.1%) in men and 10.8% (95% CI 8.6-13.5%) in women. Age and no leisure-time physical activity (LTPA) were main risk factors associated with OW/OB and AO. Living with at least one child at home and to be married in men as well as to be unemployed, to be born in South America, and a low level of education in women were associated with AO. Conclusions Men showed higher prevalence of OW and AO than women. In both sexes, age is the main risk factor associated with OW/OB and AO; in men also the absence of LTPA plays a significant role.

    Excessive consumption of discretionary foods/beverages in the Australian population has been identified, increasing the risk of obesity and chronic disease. The present study aimed to examine the associations between demographic, anthropometric and dietary factors and the consumption of discretionary foods, discretionary beverages and discretionary foods/beverages combined. Discretionary food/beverage consumption reported in two 24 h recalls was analysed, stratified by gender, age, socio-economic status, country of birth, BMI, waist circumference, and fruit and vegetable intakes. 2011-12 National Nutrition and Physical Activity Survey. Australian adults (n 7873) aged 19 years or above. Mean discretionary food and beverage consumption was 631 g (28 % by weight from foods; 72 % from beverages), providing 2721 kJ of energy intake (72 % from foods; 28 % from beverages). Total discretionary food/beverage consumption was higher in younger age groups (Pbeverage consumption (β=6·6, Pfood consumption (β=0·5, P=0·01). Total discretionary food/beverage consumption as well as discretionary foods alone and discretionary beverages alone were associated with BMI in Australian adults.

    Background: Multiple diet quality scores have been used to evaluate adherence to specific dietary recommendations or to consumption of healthful foods and nutrients. It remains unknown which score can more strongly predict longitudinal changes in cardiometabolic risk factors. Objective: We aimed to determine associations of 5 diet quality scores [AHA diet score (AHA-DS), Dietary Approaches to Stop Hypertension (DASH), Healthy Eating Index (HEI)-2005, Mediterranean diet score (MeDS), and Alternative Healthy Eating Index (AHEI)] with 2-y changes in cardiometabolic risk factors in adults 45-75 y old. Methods: Data from the Boston Puerto Rican Health Study were analyzed ( n = 1194). Diet quality scores were calculated from a baseline-validated food-frequency questionnaire. Multivariable-adjusted, repeated-subjects, mixed-effects models, adjusted for baseline measures, estimated associations between each z score and 14 individual cardiometabolic factors measured at 2 y. Results: MeDS was significantly associated with lower 2-y waist circumference (β coefficient ± SE: -0.52 ± 0.26, P = 0.048); body mass index (BMI; -0.23 ± 0.08, P = 0.005); log-insulin (-0.06 ± 0.02, P = 0.005); log-homeostasis model assessment of insulin resistance (HOMA-IR; -0.05 ± 0.02, P = 0.030), and log-C-reactive protein (-0.13 ± 0.03, P = 0.0002). Similar but weaker associations were observed for the AHEI with BMI, insulin, and HOMA-IR. The AHA-DS was inversely associated with BMI (-0.17 ± 0.08, P = 0.033). Neither the HEI-2005 nor DASH was significantly associated with any variable. Traditional Puerto Rican foods consumed by individuals with high MeDSs included vegetables and meats in homemade soups, orange juice, oatmeal, beans and legumes, fish, whole milk, corn oil, and beer. Conclusions: The MeDS comprises food components and scores associated with a favorable cardiometabolic profile over 2 y in Puerto Rican adults. An overall healthy diet may be particularly beneficial for

    Full Text Available Dried fruit is fruit that is preserved by removing the original water content naturally, through sun drying or artificially, by the use of specialized dryers or dehydrators. Dried fruit has a long tradition of use dating back to the fourth millennium BC in Mesopotamia and is prized because of its sweet taste, nutritive value and long shelf life. Traditional dried fruits such as raisins, figs, dates, apricots and prunes have been a staple of Mediterranean diets for millennia. The Mediterranean region is very favourable for production of dried fruits, not only with its climatic conditions, but also its exceptional fertile lands. Additionally, proximity to trade routes historically has allowed Mediterranean countries more access to dried fruits than landlocked countries. Today, dried fruit consumption is widespread. Nearly half of the dried fruits sold throughout the world are raisins, followed by dates, prunes (dried plums, figs, apricots, peaches, apples and pears. Dates, prunes, apricots, figs and raisins are the major dried fruits produced in the Mediterranean area. Dried fruits are not perishable but can support mold growth, some of which can produce mycotoxins. Occurence of toxigenic molds and mycotoxins on these dried fruits can be a problem in the Mediterranean basin, as in the other parts of the world, being a health hazard to the population as well as a trade issue for the export of local products. Although the most important mycotoxins occuring in Mediterranean crops are aflatoxins (B1, B2, G1 and G2 and ochratoxin A, the type and level of mycotoxins and toxigenic molds vary by crop and also by country and in some cases geographic location within a country. In this review mycotoxin risks and toxigenic fungi in date, prune and dried apricot among Mediterranean crops are reported and discussed.

    Extensive fresh fruit and vegetable production industries are developing in many parts of the world in response to the large demand for high quality fresh fruits and vegetables. Tephritid fruit flies, however, cause devastating direct losses to many of the fresh fruits and vegetables that investors target for the market place thus requiring regular insecticide treatments to protect the crop. In addition, few insects have a greater impact on international marketing and world trade in agricultural produce than the tephritid fruit flies. With expanding international trade, fruit flies, as major quarantine pests of fruits and vegetables, have taken on added importance. This will trigger additional demands by the Food and Agriculture Organization (FAO) and the International Atomic Energy Agency (IAEA) Member States to implement area-wide national or regional (transboundary) control programs against fruit fly pests. The fresh fruit and vegetable industry is facing the dual demand of rapidly rising population in developing countries which requires more production for food security and nutrition as well as a demand by developed country importers for products with pesticide residues below critical levels. As part of this process new areas are being brought into production, which require control of fruit fly pests. Developed importing countries are giving increased attention to food safety issues, partially driven by the BSE crisis, food adulteration in Western Europe and outbreaks of food borne infections in the US. Concerns over insecticide residues in fresh fruits and vegetables have become widespread particularly as it affects children who are believed to be more vulnerable. These concerns are leading to changes in regulations of permissible pesticide residues. Thus, fruit fly control methods that require minimum insecticide use are welcomed by wholesalers and consumers alike. As part of globalization, trade in fresh fruits and vegetables is being liberalized on a

    Low fruit and vegetable (FV) intake is a leading risk factor for chronic disease globally as well as in the United States. Much of the population does not consume the recommended servings of FV daily. This paper describes the development of psychosocial measures of FV intake for inclusion in the U.S. National Cancer Institute's 2007 Food Attitudes and Behaviors Survey. This was a cross-sectional study among 3,397 adults from the United States. Scales included conventional constructs shown to be correlated with fruit and vegetable intake (FVI) in prior studies (e.g., self-efficacy, social support), and novel constructs that have been measured in few- to- no studies (e.g., views on vegetarianism, neophobia). FVI was assessed with an eight-item screener. Exploratory factor analysis, Cronbach's alpha, and regression analyses were conducted. Psychosocial scales with Cronbach's alpha ≥0.68 were self-efficacy, social support, perceived barriers and benefits of eating FVs, views on vegetarianism, autonomous and controlled motivation, and preference for FVs. Conventional scales that were associated (peating FVs. Novel scales that were associated (p<0.05) with FVI were autonomous motivation, and preference for vegetables. Other single items that were associated (p<0.05) with FVI included knowledge of FV recommendations, FVI "while growing up", and daily water consumption. These findings may inform future behavioral interventions as well as further exploration of other potential factors to promote and support FVI.

    Full Text Available Objective. To assess dietary-related habits among young adults. Design and Setting. Dietary habits were assessed cross-sectionally, using a self-completed questionnaire in 193 students enrolled in public and private universities in Cyprus. Adherence to the Mediterranean diet was evaluated using the validated KIDMED index. BMI was estimated based on weight and height measurements. Results. The mean BMI was 23.31 (±3.98. The mean adherence score to the Mediterranean diet was 6.0 (IQR 4 to 8, with 26.9% of students being classified as high adherers and 21.8% as low adherers to the Mediterranean diet. About 32% of students consumed a second serving of fruit and vegetables more than once a day, whereas 26% reported going more than once a week to a fast-food restaurant and 31% consumed sweets and candy several times a day. On the other hand, 76% of participants reported consumption of at least two dairy products daily and 88% use olive oil at home. The majority consume coffee 2-3 times per day. Conclusions. Results support a shift from traditional healthy diets to more unhealthy eating patterns. However, we also report a high dairy intake and use of olive oil. Tailored-made strategies targeting the young adult population could be warranted.

    The traditional Mediterranean Diet of the early 1960s meets the characteristics of an anticancer diet defined by the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AIRC). A diet rich of whole grains, pulses, vegetables and fruits, limited in high-calorie foods (foods high in sugar or fat), red meat and foods high in salt, without sugary drinks and processed meat is recommended by the WCRF/AIRC experts to reduce the risk of cancer. The aim of this review was to examine whether Mediterranean Diet is protective or not against cancer risk. Three meta-analyses of cohort studies reported that a high adherence to the Mediterranean Diet significantly reduces the risk of cancer incidence and/or mortality. Nevertheless, the Mediterranean dietary pattern defined in the studies' part of the meta-analyses has qualitative and/or quantitative differences compared to the Mediterranean Diet of the early 1960s. Therefore, the protective role of the Mediterranean Diet against cancer has not definitely been established. In epidemiological studies, a universal definition of the Mediterranean Diet, possibly the traditional Mediterranean Diet of the early 1960s, could be useful to understand the role of this dietary pattern in cancer prevention.

This study was conducted to isolate and identify the fungi associated with bunch rot present in the body of adults of A. fraterculus collected in a commercial vineyard. From January to February 2011, adults of A. fraterculus were collected from a commercial vineyard of green grapes using adapted McPhail traps. In laboratory, flies bodies were divided into four parts (head, legs, wings, and ovipositor in Petri dishes with PDA medium to evaluate microorganisms associated. Six adult females of A. fraterculus collected in the field were also analyzed in a scanning electron microscope (SEM to identify spores of fungi. Phytopathogenic microorganisms were found in all sectioned parts. Fungal spores were recorded adhered to the body of adult females of A. fraterculus. The main species of fungi found in the body parts of A. fraterculus were Cladosporium spp. (20.2% of the obtained colonies, Botrytis cinerea Pers.

    Background: Poor diet quality is associated with a higher risk of many chronic diseases that are among the leading causes of death in the United States. It has been hypothesized that evolutionary discordance may account for some of the higher incidence and mortality from these diseases. Objective: We investigated associations of 2 diet pattern scores, the Paleolithic and the Mediterranean, with all-cause and cause-specific mortality in the REGARDS (REasons for Geographic and Racial Differences in Stroke) study, a longitudinal cohort of black and white men and women ≥45 y of age. Methods: Participants completed questionnaires, including a Block food-frequency questionnaire (FFQ), at baseline and were contacted every 6 mo to determine their health status. Of the analytic cohort (n = 21,423), a total of 2513 participants died during a median follow-up of 6.25 y. We created diet scores from FFQ responses and assessed their associations with mortality using multivariable Cox proportional hazards regression models adjusting for major risk factors. Results: For those in the highest relative to the lowest quintiles of the Paleolithic and Mediterranean diet scores, the multivariable adjusted HRs for all-cause mortality were, respectively, 0.77 (95% CI: 0.67, 0.89; P-trend diets closer to Paleolithic or Mediterranean diet patterns may be inversely associated with all-cause and cause-specific mortality.

    Evidence suggests that health benefits are associated with consuming recommended amounts of fruits and vegetables (F&V), yet standardised assessment methods to measure F&V intake are lacking. The current review aims to identify methods to assess F&V intake among children and adults in pan-European studies and inform the development of the DEDIPAC (DEterminants of DIet and Physical Activity) toolbox of methods suitable for use in future European studies. A literature search was conducted using three electronic databases and by hand-searching reference lists. English-language studies of any design which assessed F&V intake were included in the review. Studies involving two or more European countries were included in the review. Healthy, free-living children or adults. The review identified fifty-one pan-European studies which assessed F&V intake. The FFQ was the most commonly used (n 42), followed by 24 h recall (n 11) and diet records/diet history (n 7). Differences existed between the identified methods; for example, the number of F&V items on the FFQ and whether potatoes/legumes were classified as vegetables. In total, eight validated instruments were identified which assessed F&V intake among adults, adolescents or children. The current review indicates that an agreed classification of F&V is needed in order to standardise intake data more effectively between European countries. Validated methods used in pan-European populations encompassing a range of European regions were identified. These methods should be considered for use by future studies focused on evaluating intake of F&V.

    Full Text Available Citrus are native to southeastern Asia, but are present in the Mediterranean basin for centuries. This group of species has reached great importance in some of the Mediterranean countries and, in the case of orange, mandarin and lemon trees, they found here soil and climatic conditions which allows them to achieve a high level of fruit quality, even better than in the regions where they came from. Citrus fruits are present in the diet of the peoples living on the Mediterranean basin, at least since the time of the Roman Empire. In the 20th century they became the main crop in various agricultural areas of the Mediterranean, playing an important role in the landscape, in the diet of the overall population, and also in international trade. They are present in the gardens of palaces and monasteries, but also in the courtyards and orchards of the poorest families. Their fruits are not only a refreshing dessert, but also a condiment, or even a major component of many dishes. Citrus fruits have well-documented nutritional and health benefits. They can actually help prevent and cure some diseases and, above all, they are essential in a balanced and tasty diet.

    2017-05-01

    Full Text Available Background Plant-based diets have been linked to high diet quality and reduced risk of cardiovascular diseases. The health impact of plant-based diets might be partially explained by the concomitant intake of flavonoids. Estimation of flavonoids intake in adults has been important for the development of dietary recommendations and interventions for the prevention of weight gain and its consequences. However, estimation of flavonoids intake in children and adolescents is limited. Methods Average daily intake and sources of flavonoids were estimated for a representative national sample of 3,534 children and young people in Spain, aged 2–24 years. The data was collected between 1998 and 2000 by 24-h recalls. The Phenol-Explorer database and the USDA database on flavonoids content were used. Adherence to the Mediterranean diet was measured by the KIDMED index. Results The mean and median intakes of total flavonoids were 70.7 and 48.1 mg/day, respectively. The most abundant flavonoid class was flavan-3-ols (35.7%, with fruit being the top food source of flavonoids intake (42.8%. Total flavonoids intake was positively associated with the KIDMED index (p < 0.001. Conclusion The results of this study provide primary information about flavonoids intake and main food sources in Spanish children, adolescents and young adults. Participants with high daily mean intake of flavonoids have higher adherence to the Mediterranean diet.

  15. Medieval iconography of watermelons in Mediterranean Europe

    Background and Aims The watermelon, Citrullus lanatus (Cucurbitaceae), is an important fruit vegetable in the warmer regions of the world. Watermelons were illustrated in Mediterranean Antiquity, but not as frequently as some other cucurbits. Little is known concerning the watermelons of Mediterranean Europe during medieval times. With the objective of obtaining an improved understanding of watermelon history and diversity in this region, medieval drawings purportedly of watermelons were collected, examined and compared for originality, detail and accuracy. Findings The oldest manuscript found that contains an accurate, informative image of watermelon is the Tractatus de herbis, British Library ms. Egerton 747, which was produced in southern Italy, around the year 1300. A dozen more original illustrations were found, most of them from Italy, produced during the ensuing two centuries that can be positively identified as watermelon. In most herbal-type manuscripts, the foliage is depicted realistically, the plants shown as having long internodes, alternate leaves with pinnatifid leaf laminae, and the fruits are small, round and striped. The manuscript that contains the most detailed and accurate image of watermelon is the Carrara Herbal, British Library ms. Egerton 2020. In the agriculture-based manuscripts, the foliage, if depicted, is not accurate, but variation in the size, shape and coloration of the fruits is evident. Both red-flesh and white-flesh watermelons are illustrated, corresponding to the typical sweet dessert watermelons so common today and the insipid citron watermelons, respectively. The variation in watermelon fruit size, shape and coloration depicted in the illustrations indicates that at least six cultivars of watermelon are represented, three of which probably had red, sweet flesh and three of which appear to have been citrons. Evidently, citron watermelons were more common in Mediterranean Europe in the past than they are today. PMID:23904443

    High cost of healthy foods could be a barrier to healthy eating. We aimed to examine the association between dietary cost and adherence to the Mediterranean diet in a non-Mediterranean country. We evaluated cross-sectional data from 12,417 adults in the UK Fenland Study. Responses to 130-item food frequency questionnaires were used to calculate a Mediterranean diet score (MDS). Dietary cost was estimated by matching food consumption data with retail prices of five major supermarkets. Using multivariable-adjusted linear regression, we examined the association of MDS and individual foods with dietary cost in absolute and relative scales. Subsequently, we assessed how much the association was explained by education, income, marital status, and occupation, by conducting mediation analysis and testing interaction by these variables. High compared to low MDS (top to bottom third) was associated with marginally higher cost by 5.4% (95% CI 4.4. 6.4%) or £0.20/day (£0.16, 0.25). Participants with high adherence had higher cost associated with the healthier components (e.g. vegetables, fruits, and fish), and lower cost associated with the unhealthy components (e.g. red meat, processed meat and sweets) (pMediterranean diet was associated with marginally higher dietary cost, partly modified and explained by socio-economic status, but the potential economic barriers of high adherence might be offset by cost saving from reducing unhealthy food consumption.

    Our aim was to assess the association of a Mediterranean diet and gastroesophageal reflux disease among adult men and women in Albania, a former communist country in South Eastern Europe with a predominantly Muslim population. A cross-sectional study was conducted in 2012, which included a population-based sample of 817 individuals (≥18 years) residing in Tirana, the Albanian capital (333 men; overall mean age: 50.2 ± 18.7 years; overall response rate: 82%). Assessment of gastroesophageal reflux disease was based on Montreal definition. Participants were interviewed about their dietary patterns, which in the analysis was dichotomized into: predominantly Mediterranean (frequent consumption of composite/traditional dishes, fresh fruit and vegetables, olive oil, and fish) versus largely non-Mediterranean (frequent consumption of red meat, fried food, sweets, and junk/fast food). Logistic regression was used to assess the association of gastroesophageal reflux disease with the dietary patterns. Irrespective of demographic and socioeconomic characteristics and lifestyle factors including eating habits (meal regularity, eating rate, and meal-to-sleep interval), employment of a non-Mediterranean diet was positively related to gastroesophageal reflux disease risk (fully adjusted odds ratio = 2.3, 95% confidence interval = 1.2-4.5). Our findings point to a beneficial effect of a Mediterranean diet in the occurrence of gastroesophageal reflux disease in transitional Albania. Findings from this study should be confirmed and expanded further in prospective studies in Albania and in other Mediterranean countries. © 2015 International Society for Diseases of the Esophagus.

    The association between the consumption of seafood and its benefits on cardiovascular (CVD) risk can be challenged by its heavy metal (HM) content. This study aimed to explore the association of seafood consumption and its estimated HM contents with the lipid profile and lipid oxidation biomarkers in adults from a Spanish Mediterranean area who do not present risk factors for CVD. In this cross-sectional study, the clinical history, three-day dietary record, lipid profile (LDLc, HDLc, APOB/A, and triglyceride levels), plasma oxidised LDL (oxLDL) and 8-isoprostane levels of 81 adults without risk factors for CVD [43% men, with a mean age of 43.6 years (95%CI: 40.1-47.1)] were assessed. The HM [arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb)] contents of seafood were estimated according to data from analyses of marine species in the same Mediterranean area. Moderate adherence to the Mediterranean diet (score: 4.6 of 9) with a mean seafood consumption of 74.9g/day (95%CI: 59.9-89.9), including 22.7g of shellfish per day (95%CI: 13.5-31.9), was observed. The estimated HM contents were lower than the provisional tolerable weekly intakes (PTWIs): 21.12µg/kg/week As, 0.57µg/kg/week InAs, 0.15µg/kg/week Cd, 1.11µg/kg/week Hg and 0.28µg/kg/week Pb. After adjusting by confounder variables, an increase in shellfish consumption was associated with increases in the levels of LDLc (P=0.013), non-HDLc (P=0.015), APOB/A (P=0.02) and plasma oxLDL (P=0.002). Moreover, an increase in the estimated As and Hg levels in shellfish was associated with an increase in LDLc (P=0.015 and P=0.018, respectively), non-HDLc (Pconsumption, even by a moderate amount, could favour a pro-atherogenic lipid profile and a higher level of oxidised LDL. These associations are likely influenced by the estimated exposure to As and Hg from shellfish despite these values are lower than the PTWIs. Copyright © 2017 Elsevier Inc. All rights reserved.

    There is a link between joint and gut inflammation of unknown etiology in arthritis. Existing research indicates that regular consumption of high-fructose corn syrup sweetened (HFCS) soft drinks, but not diet soft drinks, may be associated with increased risk of seropositive rheumatoid arthritis (RA) in women, independent of other dietary and lifestyle factors. One unexplored hypothesis for this association is that fructose malabsorption, due to regular consumption of excess free fructose (EFF) and HFCS, contributes to fructose reactivity in the gastrointestinal tract and intestinal in situ formation of enFruAGEs, which once absorbed, travel beyond the intestinal boundaries to other tissues and promote inflammation. In separate studies, the accumulation of advanced glycation end-products has been associated with joint inflammation in RA. Objective of this study was to assess the association between EFF beverages intake and non-age, non-wear and tear-associated arthritis in US young adults. In this cross sectional study of 1209 adults aged 20-30y, (Nutrition and Health Examination Surveys 2003-2006) exposure variables were high EFF beverages, including HFCS sweetened soft drinks, and any combination of HFCS sweetened soft drinks, fruit drinks (FD) and apple juice, referred to as tEFF. Analyses of diet soda and diet FD were included for comparison. The outcome was self-reported arthritis. Rao Scott Ҳ(2) was used for prevalence differences and logistic regression for associations, adjusted for confounders. Young adults consuming any combination of high EFF beverages (tEFF) ⩾5 times/week (but not diet soda) were three times as likely to have arthritis as non/low consumers (odds ratios=3.01; p⩽0.021; 95% confidence intervals=1.20-7.59), independent of all covariates, including physical activity, other dietary factors, blood glucose and smoking. EFF beverage intake is significantly associated with arthritis in US adults aged 20-30 years, possibly due to the

    Objectives There is increasing evidence to suggest an association between sleep and diet. The aim of the present study was to examine the association between sleep duration and fruit/vegetable (FV) intakes and their associated biomarkers in UK adults. Design Cross-sectional. Setting Data from The National Diet and Nutrition Survey. Participants 1612 adults aged 19–65 years were included, pregnant/breastfeeding women were excluded from the analyses. Outcome measures Sleep duration was assessed by self-report, and diet was assessed by 4-day food diaries, disaggregation of foods containing FV into their components was conducted to determine total FV intakes. Sleep duration was divided into: short (8 hours/day) sleep periods. Multiple regression adjusting for confounders was used for analyses where sleep duration was the exposure and FV intakes and their associated biomarkers were the outcomes. Restricted cubic spline models were developed to explore potential non-linear associations. Results In adjusted models, long sleepers (LS) consumed on average 28 (95% CI −50 to −6, p=0.01) g/day less of total FV compared to reference sleepers (RS), whereas short sleepers (SS) consumed 24 g/day less (95% CI −42 to –6, p=0.006) and had lower levels of FV biomarkers (total carotenoids, β-carotene and lycopene) compared to RS. Restricted cubic spline models showed that the association between sleep duration and FV intakes was non-linear (pimportant implications for lifestyle and behavioural change policy. PMID:29703857

    Increasing consumption of non-nutrient-dense foods (NNDF), decreasing consumption of traditional foods (TF) and low consumption of fruit and vegetables (FV) may contribute to increasing chronic disease rates amongst Inuit. The present study aimed to assess the daily frequency and socioeconomic and demographic factors influencing consumption of TF, FV and NNDF amongst Inuit adults in Nunavut, Canada. Using a cross-sectional study design and random household sampling in three communities in Nunavut, a food frequency questionnaire developed for the population was used to assess frequency of NNDF, TF and FV consumption amongst Inuit adults. Socioeconomic status (SES) was assessed by education level, ownership of items in working condition, and whether or not people in the household were employed or on income support. Mean frequencies of daily consumption were compared across gender and age groups, and associations with socioeconomic indicators were analysed using logistic regression. Two hundred and eleven participants (36 men, 175 women; mean (standard deviation) ages 42.1 (15.0) and 42.2 (13.2) years, respectively; response rate 69-93%) completed the study. Mean frequencies of consumption for NNDF, TF and FV were 6.3, 1.9 and 1.6 times per day, respectively. On average, participants ≤50 years consumed NNDF (P=0.003) and FV (P=0.01) more frequently and TF (P=0.01) less frequently than participants >50 years. Education was positively associated with FV consumption and negatively associated with TF consumption. Households on income support were more likely to consume TF and NNDF. These results support the hypothesis that the nutrition transition taking place amongst Inuit in Nunavut results in elevated consumption of NNDF compared with TF and FV. © 2010 The Authors.

    Food spoilage is a common problem when marketing agricultural products. Promising results have already been obtained on a number of food irradiating applications. A process is described in this paper where irradiation of sub-tropical fruits, especially mangoes and papayas, combined with conventional heat treatment results in effective insect and fungal control, delays ripening and greatly improves the quality of fruit at both export and internal markets

    Full Text Available Growth rates of the juvenile phase of loggerhead turtles (Caretta caretta were estimated for the first time in the Mediterranean Sea from capture-mark-recapture records. Thirty-eight turtles were released from Italian coasts and re-encountered after 1.0-10.9 years in the period 1986-2007. Their mean CCL (curved carapace length ranged from 32.5 to 82.0 cm and they showed variable growth rates, ranging from 0 to 5.97 cm/yr (mean: 2.5. The association between annual growth rate and three covariates (mean year, mean size and time interval was investigated through a non-parametric modelling approach. Only mean size showed a clear effect on growth rate, described by a monotonic declining curve. Variability indicates that factors not included in the model, probably individual-related ones, have an important effect on growth rates. Based on the monotonic decreasing growth function which indicates no growth spurt, a von Bertalanffy growth function was used to estimate the time required by turtles to grow within the observed size range. The results indicate that turtles would take 16-28 years to reach 66.5-84.7 cm CCL, the average nesting female sizes observed at the most important Mediterranean nesting sites, which can be considered an approximation of the size at maturity.

    The Mediterranean diet has been demonstrated to provide a range of health benefits in observational and clinical trials and adopted by various dietary guidelines. However, a broad range of definitions exist impeding synthesis across trials. This review aims to provide a historical description of Mediterranean diets, from the ancient to the modern, to inform future educational and diet index tool development representing the 'traditional' Mediterranean diet. Nine databases were searched from inception to July 2015 to identify papers defining the Mediterranean diet. The definition accepted by the United Nations Educational, Scientific and Cultural Organization (UNESCO) was also reviewed. The 'traditional' Mediterranean diet is described as high in unprocessed plant foods (grains, vegetables, fruits, legumes, nuts/seeds and extra virgin olive oil), moderate in fish/shellfish and wine and low in meat, dairy, eggs, animal fats and discretionary foods. Additional elements relating to cuisine and eating habits identified in this review include frequent intake of home cooked meals; use of moist, lower temperature, cooking methods; eating main meals in company; reduced snacking occasions; fasting practice; ownership of a vegetable garden; use of traditional foods and combinations; and napping after the midday meal. Scope exists for future tools to incorporate additional elements of the 'traditional' Mediterranean diet to improve the quality, consistency, and synthesis of ongoing research on the Mediterranean diet.

    Full Text Available The aim of this paper is to give a description of the Mediterranean fisheries, and its level of exploitation and to address the main questions dealing with its management. The Mediterranean is a semi-enclosed marine area with generally narrow continental shelves. The primary production of the Mediterranean is among the lowest in the world (26-50g C m-2 y-1. The Mediterranean fisheries can be broken down into three main categories: small scale fisheries, trawling and seining fisheries, which operated on demersal, small pelagic and large pelagic resources. After a general description of the state of the resources in the different areas of the Mediterranean it is concluded that (a the overall pictures from the western to the eastern Mediterranean are not considerably different, (b the total landings in the Mediterranean have been increased the last decades, and (c from the perspective of stock assessment, the very few available time series data show stable yield levels. In general fisheries management in the Mediterranean is at a rela- tively early stage of development, judging by the criteria of North Atlantic fisheries. Quota systems are generally not applied, mesh-size regulations usually are set at low levels relative to scientific advice, and effort limitation is not usually applied or, if it is, is not always based on a formal resource assessment. The conservation/management measures applied by the Mediterranean countries can be broadly separated into two major categories: those aiming to keep the fishing effort under control and those aiming to make the exploitation pattern more rational. The most acute problems in the management of the Mediterranean resources are the multispecificity of the catches and the lack of reliable official statistics.

    Full Text Available The aim was to assess inflammatory markers among adults and adolescents in relation to the adherence to the Mediterranean diet. A random sample (219 males and 379 females of the Balearic Islands population (12–65 years was anthropometrically measured and provided a blood sample to determine biomarkers of inflammation. Dietary habits were assessed and the adherence to the Mediterranean dietary pattern calculated. The prevalence of metabolic syndrome increased with age in both sexes. The adherence to the Mediterranean diet in adolescent males was 51.3% and 45.7% in adults, whereas in females 53.1% and 44.3%, respectively. In males, higher adherence to the Mediterranean diet was associated with higher levels of adiponectin and lower levels of leptin, tumor necrosis factor alpha (TNF-α, plasminogen activator inhibitor 1 (PAI-1 and high-sensitivity C-reactive protein (hs-CRP in adults, but not in young subjects. In females, higher adherence was associated with lower levels of leptin in the young group, PAI-1 in adults and hs-CRP in both groups. With increasing age in both sexes, metabolic syndrome increases, but the adherence to the Mediterranean diet decreases. Low adherence to the Mediterranean dietary pattern (MDP is directly associated with a worse profile of plasmatic inflammation markers.

    Full Text Available The aim of the present study was to investigate the total water intake (TWI from drinks and foods and to evaluate the correlation between the different types of drinks on energy and antioxidant intake. The cohort comprised 1602 individuals from the city of Catania in Southern Italy. A food frequency questionnaire was administered to assess dietary and water intake. The mean total water intake was 2.7 L; more than about two thirds of the sample met the European recommendations for water intake. Water and espresso coffee were the most consumed drinks. Alcohol beverages contributed about 3.0% of total energy intake, and sugar sweetened beverages contributed about 1.4%. All antioxidant vitamins were significantly correlated with TWI. However, a higher correlation was found for water from food rather than water from beverages, suggesting that major food contributors to antioxidant vitamin intake might be fruits and vegetables, rather than beverages other than water. A mild correlation was found between fruit juices and vitamin C; coffee, tea and alcohol, and niacin and polyphenols; and milk and vitamin B12. The findings from the present study show that our sample population has an adequate intake of TWI and that there is a healthy association between beverages and dietary antioxidants.

    The biological effects of larval rearing diet acidity on the developmental stages of the medfly C. capitata (Wied.) were studied at the laboratory scale. Diets were formulated at five different initial pH ranging from 4.59 to 2.09 together with the control group currently used in our laboratory (5.26). These effects were evaluated on larval period, percent pupal recovery, pupal weight, percent adult emergence, percent male production and adult flight ability. The results showed that the shortest larval development occurred at pH 3.48 and 3.75, the highest pupal recovery at pH 3.75, the best pupal weight at pH 2.09, 3.48, 3.75 and 4.59, the highest percent adult emergence at pH 3.75, the highest percentage male production at pH 3.48, and the best percentage of fliers at pH 4.59. The obtained data referred to the optimizing physiochemical factors such as pH can improve the overall yield of mass reared medfly in the laboratory to be irradiated by gamma radiation and released in the field for controlling the insect

    Although attention-deficit/hyperactivity disorder (ADHD) has been related to nutrient deficiencies and "unhealthy" diets, to date there are no studies that examined the relationship between the Mediterranean diet and ADHD. We hypothesized that a low adherence to a Mediterranean diet would be positively associated with an increase in ADHD diagnosis. A total of 120 children and adolescents (60 with newly diagnosed ADHD and 60 controls) were studied in a sex- and age-matched case-control study. ADHD diagnosis was made according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision. Energy, dietary intake, adherence to a Mediterranean diet, and familial background were measured. Logistic regression was used to determine associations between the adherence to a Mediterranean diet and ADHD. Lower adherence to a Mediterranean diet was associated with ADHD diagnosis (odds ratio: 7.07; 95% confidence interval: 2.65-18.84; relative risk: 2.80; 95% confidence interval: 1.54-5.25). Both remained significant after adjusting for potential confounders. Lower frequency of consuming fruit, vegetables, pasta, and rice and higher frequency of skipping breakfast and eating at fast-food restaurants were associated with ADHD diagnosis (P Mediterranean diet might play a role in ADHD development. Our data support the notion that not only "specific nutrients" but also the "whole diet" should be considered in ADHD. Copyright © 2017 by the American Academy of Pediatrics.

    Lung cancer in men and breast cancer in women are the most commonly diagnosed cancers in Poland and worldwide. Results of studies involving dietary patterns (DPs) and breast or lung cancer risk in European countries outside the Mediterranean Sea region are limited and inconclusive. This study aimed to develop a 'Polish-adapted Mediterranean Diet' ('Polish-aMED') score, and then study the associations between the 'Polish-aMED' score and a posteriori -derived dietary patterns with breast or lung cancer risk in adult Poles. This pooled analysis of two case-control studies involved 560 subjects (280 men, 280 women) aged 40-75 years from Northeastern Poland. Diagnoses of breast cancer in 140 women and lung cancer in 140 men were found. The food frequency consumption of 21 selected food groups was collected using a 62-item Food Frequency Questionnaire (FFQ)-6. The 'Polish-adapted Mediterranean Diet' score which included eight items-vegetables, fruit, whole grain, fish, legumes, nuts and seeds-as well as the ratio of vegetable oils to animal fat and red and processed meat was developed (range: 0-8 points). Three DPs were identified in a Principal Component Analysis: 'Prudent', 'Non-healthy', 'Dressings and sweetened-low-fat dairy'. In a multiple logistic regression analysis, two models were created: crude, and adjusted for age, sex, type of cancer, Body Mass Index (BMI), socioeconomic status (SES) index, overall physical activity, smoking status and alcohol abuse. The risk of breast or lung cancer was lower in the average (3-5 points) and high (6-8 points) levels of the 'Polish-aMED' score compared to the low (0-2 points) level by 51% (odds ratio (OR): 0.49; 95% confidence interval (Cl): 0.30-0.80; p Mediterranean diet could be considered for adults living in non-Mediterranean countries for the prevention of the breast or lung cancers. Future studies should explore the role of a traditional Mediterranean diet fitted to local dietary patterns of non-Mediterranean Europeans

    Mediterranean countries are not traditionally coal producers. In France, the main mines were located in the North and East, and belonged to the great coal fields of northern Europe. Spain is a modest producer (ten million tonnes), as is Turkey with its three million tonnes. The only way most of these mines can stand up to international competition is by an array of protectionistic measures and subsidies. This state of affairs has marked events of quite another nature, as it relates to energy economics. That is, coal has taken on increasing importance in the energy supplies of all the countries of the Mediterranean zone over the past twenty years. In this article, we set out by describing coke supply for the Mediterranean ensemble, and then go on to analyze the development aspects of coal for electrical production, the future of Mediterranean lignite, and the supply of imported coal. 4 refs., 11 figs., 3 tabs

    To our knowledge, no data have yet shown the combined effects of GSTM1/GSTT1 gene polymorphisms with high consumption of a fruit and vegetable diet on the body's antioxidant capacity. A 2-wk dietary intervention in healthy participants was conducted to test the hypothesis that the antioxidant biomarkers in individuals with different glutathione-S-transferases (GST) genotypes will be different in response to a high fruit-juice and vegetable diet. In our study, 24 healthy volunteers with different GST genotypes (12 GSTM1+/GSTT1+ and 12 GSTM1-/GSTT1- participants) consumed a controlled diet high in fruit-juice and vegetables for 2 wk. Blood and first-void urine specimens were obtained at baseline, 1-wk, and 2-wk intervals. The antioxidant capacity-related biomarkers in blood and urine were observed and recorded at the scheduled times. Erythrocyte GST and glutathione reductase (GR) activities response to a high fruit-juice and vegetable diet are GST genotype-dependent. Two weeks on the high fruit-juice and vegetable diet increased GST and GR activities in the GSTM1+/GSTT1+ group (P juice and vegetable diet than GSTM1-/GSTT1- participants.

    This article aimed at assessing the 10-year trends (2000-2010) in the prevalence of overweight and obesity among the Balearic Islands' adult population. Body mass index (BMI, kg/m2) for young (18-35 year-olds) and middle-aged (36-55 year-olds) adults living in the Balearics was calculated. Data represented 1,089 people during 1999-2000 and 1,081 people during 2009-2010. The BMI categories were as follows: normal weight (18.5 obese (≥30). Weighted frequency estimates and logistic regression analysis were used to calculate overweight and obesity trends. While the prevalence of overweight and obesity mostly remained stable over the 2000-2010 period, the prevalence of obesity increased from 5.1 to 8.3% in young adults (aged 18-35), a 1.66-fold increase in prevalence (95% CI 1.02-2.70) over the study period. Total overweight and obesity prevalence remained stable in the Balearic adult population; however, a rising prevalence of obesity has been observed in young adults, which suggests a need to develop and change current strategies in order to reverse the current trends in obesity among this age group. © 2015 S.

    Dietary guidelines to promote good health are usually based on foods, nutrients, and dietary patterns predictive of chronic disease risk in epidemiologic studies. However, sound nutritional recommendations for cardiovascular prevention should be based on the results of large randomized clinical trials with "hard" end-points as the main outcome. Such evidence has been obtained for the Mediterranean diet from the PREDIMED (Prevención con Dieta Mediterránea) trial and the Lyon Heart Study. The traditional Mediterranean diet was that found in olive growing areas of Crete, Greece, and Southern Italy in the late 1950s. Their major characteristics include: a) a high consumption of cereals, legumes, nuts, vegetables, and fruits; b) a relatively high-fat consumption, mostly provided by olive oil; c) moderate to high fish consumption; d) poultry and dairy products consumed in moderate to small amounts; e) low consumption of red meats, and meat products; and f) moderate alcohol intake, usually in the form of red wine. However, these protective effects of the traditional Mediterranean diet may be even greater if we upgrade the health effects of this dietary pattern changing the common olive oil used for extra-virgin olive oil, increasing the consumption of nuts, fatty fish and whole grain cereals, reducing sodium intake, and maintaining a moderate consumption of wine with meals. © 2013 Elsevier B.V.

    Recent studies have demonstrated that consumption of Opuntia ficus-indica Mill. has an important positive health benefit, mainly due to antioxidant properties, which justifies this research. This study examined antioxidant activity, organic acid and sugar profile, total phenolic, and physicochemical characteristics of six O. ficus-indica cultivars growing in the Spanish Mediterranean. It should be noted that, in this study, both cladodes (young and adult) and fruits (peel and pulp) were analyzed. The antioxidant activity (2,2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) and 2,2-diphenyl-1-picrylhydrazyl methods) was higher in fruit peel than in cladodes. The young cladodes presented an important antioxidant activity by the ferric-reducing ability of plasma method as well as a higher total phenolic content (18.90 g gallic acid equivalent per kilogram). High-performance liquid chromatography (HPLC) with diode-array detector analysis revealed the absence of sucrose and the presence of glucose and fructose, which the values were higher in pulp fruits. HPLC with refractive index detector analysis showed that citric, malic, and succinic acids were the main organic acids in all cultivars, with a significant higher content in old cladodes. These investigations valorize O. ficus-indica fruits in comparison with cladodes. In general, this plant can be considered as an ingredient for the production of health-promoting food, highlighting mainly in the antioxidant activity and total polyphenols content found in young cladodes and peel fruits. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    2017-04-01

    Type 2 diabetes and obesity are possible risk factors for Alzheimer’s disease and these can be modified by physical activity and changes in dietary patterns, such as switching to a Mediterranean diet. This diet includes fruits, vegetables, olive oil, fish and moderate wine intake. These foods provide vitamins, polyphenols and unsaturated fatty acids. This diet should be able to reduce oxidative stress. The inflammatory response is also reduced by unsaturated fatty acids, resulting in a lower expression and a lower production of pro-inflammatory cytokines. The Cardiovascular protection is related to the actions of polyphenols and unsaturated fatty acids on the vascular endothelium. The Mediterranean diet also can improve cardiovascular risk factors such as dyslipidemia, hypertension and metabolic syndrome. These beneficial effects of the Mediterranean diet should have a role in Alzheimer’s disease prevention.

    Field-cage experiments were performed to determine the effectiveness of MultiLure traps (Better World MFG Inc., Fresno, CA) baited with NuLure (Miller Chemical and Fertilizer Corp., Hanover, PA) or BioLure (Suterra LLC, Inc., Bend, OR) in capturing individually marked Mexican fruit fly, Anastrepha ludens (Loew), and West Indian fruit fly, Anastrepha obliqua (Macquart) (Diptera: Tephritidae), of both sexes. Experimental treatments involved wild and laboratory-reared flies of varying ages (2-4 and 15-18 d) and dietary histories (sugar only, open fruit, open fruit plus chicken feces, and hydrolyzed protein mixed with sugar). Data were divided into two parts: total captures over a 24-h period and trap visits/landings, entrances into interior of trap ,and effective captures (i.e., drowning in liquid bait or water) over a 5-h detailed observation period (0600-1100 hours). The response to the two baits varied by fly species, gender, physiological state, age, and strain. Importantly, there were several highly significant interactions among these factors, underlining the complex nature of the response. The two baits differed in attractiveness for A. obliqua but not A. ludens. The effect of strain (wild versus laboratory flies) was significant for A. ludens but not A. obliqua. For effect of dietary history, adults of both species, irrespective of sex, were significantly less responsive to both baits when fed on a mixture of protein and sugar when compared with adults fed the other diets. Finally, we confirmed previous observations indicating that McPhail-type traps are quite inefficient. Considering the total 24-h fly tenure in the cage, and independent of bait treatment and fly type (i.e., strain, adult diet, gender and age), of a total of 2,880 A. obliqua and 2,880 A. ludens adults released into the field cages over the entire study (15 replicates), only 564 (19.6%) and 174 (6%) individuals, respectively, were effectively caught.

    Full Text Available Neofusicoccum luteum is reported for the first time from olives (Olea europaea, causing fruit rot and leaf necrosis. Affected fruits initially became brown with pycnidia developing on the surface, later drying out and becoming mummified. The fungus was shown to be pathogenic on both fruits and leaves. The association of Botryosphaeriaceae with rotting olive fruits in Mediterranean regions and in New South Wales, Australia indicates that these fungi play a significant role in fruit rots of olives and deserve greater attention.

    Full Text Available Familial Mediterranean Fever is an autosomal recessive inherited disease with a course of autoinflammation, which is characterized by the episodes of fever and serositis. It affects the populations from Mediterranean basin. Genetic mutation of the disease is on MEFV gene located on short arm of Chromosome 16. The disease is diagnosed based on clinical evaluation. Amyloidosis is the most important complication. The only agent that decreases the development of amyloidosis and the frequency and severity of the episodes is colchicine, which has been used for about 40 years. In this review, we aimed to discuss especially the most recent advances about Familial Mediterranean Fever which is commonly seen in our population.

    Full Text Available Cliffs worldwide are known to be reservoirs of relict biodiversity. Despite the presence of harsh abiotic conditions, large endemic floras live in such environments. Primula palinuri Petagna is a rare endemic plant species, surviving on cliff sites along a few kilometres of the Tyrrhenian coast in southern Italy. This species is declared at risk of extinction due to human impact on the coastal areas in question. Population surveys have shown that most of the plants are old individuals, while seedlings and plants at early stages of development are rare. We followed the growth of P. palinuri plants from seed germination to the adult phase and analysed the morphoanatomical traits of plants at all stages of development. Our results showed that the pressure of cliff environmental factors has been selected for seasonal habitus and structural adaptive traits in this species. The main morphoanatomical modifications are suberized cell layers and accumulation of phenolic compounds in cell structures. These features are strictly related to regulation of water uptake and storage as well as defence from predation. However, we found them well established only in adult plants and not in juvenile individuals. These findings contribute to explain the rare recruitment of the present relict populations, identifying some of the biological traits which result in species vulnerability.

    Transitions in nutrition patterns tend to emerge through industrialization and economic development. We hypothesized that the dietary patterns among South Korean adults who were 20 years or older have changed significantly from 1998 to 2010. Herein, a repeated cross-sectional analysis of data was followed for 140601 adults. We noted changes in consumption, after adjusting for age, sex, body mass index, and exercise, and tested the trends across the study period. Factor and cluster analyses were used to derive dietary patterns. A decrease in traditional Korean food consumption, including cereals, vegetables (252-176 g), and Kimchi (127-82 g), occurred, whereas fruit (172-252 g), egg, and fried food intakes increased (P dietary patterns: "Korean" diet (rice, vegetables, and Kimchi), "Western" diet (soda, eggs, and oil), and "New" diet (low sugar and high fruit and dairy product intakes). Compared to 1998, approximately 40% of participants still followed a Korean diet in 2010. Interestingly, the popularity of the Western diet fell by approximately 20%, whereas the new diet pattern increased 2-fold over the study period. Overall, these data show secular trends in dietary patterns that included a preservation of the traditional Korean diet and the emergence of a new diet pattern, and it demonstrated a unique transition in food and nutrient intakes in Korea.

    To assess the adherence to the Mediterranean diet in the population of Dalmatia in southern Croatia. A cross-sectional study was performed within the 10001 Dalmatians cohort, encompassing 2768 participants from Korčula and Vis islands and the City of Split, who were recruited during 2011-2014. Using the data obtained from food frequency questionnaire we calculated the Mediterranean Diet Serving Score (MDSS). Multivariate logistic regression was used to identify the characteristics associated with the adherence to the Mediterranean diet, with age, sex, place of residence, education attainment, smoking, and physical activity as covariates. The median MDSS score was 11 out of maximum 24 points (interquartile range 8-13), with the highest score recorded on the island of Vis. Participants reported a dietary pattern that had high compliance with the Mediterranean diet guidelines for consumption of cereals (87% met the criteria), potatoes (73%), olive oil (69%), and fish (61%), moderate for consumption of fruit (54%) and vegetables (31%), and low for consumption of nuts (6%). Overall, only 23% of the participants were classified as being adherent to the Mediterranean diet, with a particularly low percentage among younger participants (12%) compared to the older ones (34%). Men were less likely to show good adherence (odds ratio 0.52, 95% confidence interval 0.42-0.65). This study revealed rather poor compliance with the current recommendations on the Mediterranean diet composition in the population of Dalmatia. Public health intervention is especially needed in younger age groups and in men, who show the greatest departure from traditional Mediterranean diet and lifestyle.

    Full Text Available BACKGROUND: A Mediterranean diet has a recognized beneficial effect on health and longevity, with a protective influence on several cancers. However, its association with breast cancer risk remains unclear. OBJECTIVE: We aimed to investigate whether adherence to a Mediterranean dietary pattern influences breast cancer risk. DESIGN: The Swedish Women's Lifestyle and Health cohort study includes 49,258 women aged 30 to 49 years at recruitment in 1991-1992. Consumption of foods and beverages was measured at enrollment using a food frequency questionnaire. A Mediterranean diet score was constructed based on the consumption of alcohol, vegetables, fruits, legumes, cereals, fish, the ratio of unsaturated to saturated fat, and dairy and meat products. Relative risks (RR for breast cancer and specific tumor characteristics (invasiveness, histological type, estrogen/progesterone receptor status, malignancy grade and stage associated with this score were estimated using Cox regression controlling for potential confounders. RESULTS: 1,278 incident breast cancers were diagnosed. Adherence to a Mediterranean dietary pattern was not statistically significantly associated with reduced risk of breast cancer overall, or with specific breast tumor characteristics. A RR (95% confidence interval for breast cancer associated with a two-point increment in the Mediterranean diet score was 1.08 (1.00-1.15 in all women, and 1.10 (1.01-1.21 and 1.02 (0.91-1.15 in premenopausal and postmenopausal women, respectively. When alcohol was excluded from the Mediterranean diet score, results became not statistically significant. CONCLUSIONS: Adherence to a Mediterranean dietary pattern did not decrease breast cancer risk in this cohort of relatively young women.

    The production of mandarins is important in the Mediterranean area, where the continued use of saline water reduces fruit yield and modifies fruit quality. Grafted trees of Clemenules mandarin scion on Carrizo citrange and Cleopatra mandarin rootstocks, two of the most common citrus rootstocks employed in this area, were irrigated with two saline treatments (control and 30 mM NaCl). The fruit quality was studied through the last two months before the fruit harvest. Salinity reduced both the fruit number and the mean fruit weight on Carrizo trees whereas no fruit weight reduction was observed on Cleopatra. The decrease of fruit weight on Carrizo trees is probably due to the lower water content and consequently the lower juice percentage. Although the saline treatment produced significant differences in some fruit quality variables (shape and thickness indices) throughout the maturation process, they were minimal at the harvest time. Total soluble solids (TSS) were significantly higher in fruits from the saline treatments, probably due to a passive dehydration. It is also possible that de novo synthesis of sugars occurred, since fruits from Cleopatra trees receiving the saline treatment had similar water contents but higher TSS than control fruits. The external fruit colour indicated that the saline treatment accelerated the maturation process; however, the maturity index showed that the high acidity of these fruits delayed the internal maturation with respect to the control fruits.

    Familial Mediterranean fever (FMF) is the most prevalent genetically determined autoinflammatory disease. FMF significantly decreases the quality of life and limits life expectancy due to the development of amyloidosis in affected individuals. Prevalence of FMF is highest in the south-eastern Mediterraneans. In other parts of the world, its occurance is often restricted to high-risk ethnic groups. In Central Europe, experience with FMF is scarse to none, as in the case of Slovakia, where no cases have been reported, so far. Herein we report the first five patients (3 adults and 2 children, 4 native Slovaks) in whom the diagnosis of FMF could be confirmed in Slovakia. Our experience demonstrates that FMF does occur in low-risk populations in Central Europe. Due to low prevalence and lack of experience, FMF diagnosis may be significantly delayed (4.5-30 years) and undiagnosed cases are to be expected in our population.

    Full Text Available Widespread in the Mediterranean basin, Olea europaea trees are gaining worldwide popularity for the nutritional and cancer-protective properties of the oil, mechanically extracted from ripe fruits. Fruit development is a physiological process with remarkable impact on the modulation of the biosynthesis of compounds affecting the quality of the drupes as well as the final composition of the olive oil. Proteomics offers the possibility to dig deeper into the major changes during fruit development, including the important phase of ripening, and to classify temporal patterns of protein accumulation occurring during these complex physiological processes.In this work, we started monitoring the proteome variations associated with olive fruit development by using comparative proteomics coupled to mass spectrometry. Proteins extracted from drupes at three different developmental stages were separated on 2-DE and subjected to image analysis. 247 protein spots were revealed as differentially accumulated. Proteins were identified from a total of 121 spots and discussed in relation to olive drupe metabolic changes occurring during fruit development. In order to evaluate if changes observed at the protein level were consistent with changes of mRNAs, proteomic data produced in the present work were compared with transcriptomic data elaborated during previous studies.This study identifies a number of proteins responsible for quality traits of cv. Coratina, with particular regard to proteins associated to the metabolism of fatty acids, phenolic and aroma compounds. Proteins involved in fruit photosynthesis have been also identified and their pivotal contribution in oleogenesis has been discussed. To date, this study represents the first characterization of the olive fruit proteome during development, providing new insights into fruit metabolism and oil accumulation process.

    Although reviews of the association between polyphenol intake and cognition exist, research examining the cognitive effects of fruit, vegetable, and juice consumption across epidemiological and intervention studies has not been previously examined. For the present review, critical inclusion criteria were human participants, a measure of fruit, vegetable, or 100% juice consumption, an objective measure of cognitive function, and a clinical diagnosis of neuropsychological disease. Studies were excluded if consumption of fruits, vegetables, or juice was not assessed in isolation from other food groups, or if there was no statistical control for education or IQ. Seventeen of 19 epidemiological studies and 3 of 6 intervention studies reported significant benefits of fruit, vegetable, or juice consumption for cognitive performance. The data suggest that chronic consumption of fruits, vegetables, and juices is beneficial for cognition in healthy older adults. The limited data from acute interventions indicate that consumption of fruit juices can have immediate benefits for memory function in adults with mild cognitive impairment; however, as of yet, acute benefits have not been observed in healthy adults. Conclusions regarding an optimum dietary intake for fruits, vegetables, and juices are difficult to quantify because of substantial heterogeneity in the categorization of consumption of these foods. © 2014 International Life Sciences Institute.

    Full Text Available ABSTRACT Diachasmimorpha longicaudata is an Old World parasitoid of tephritid fruit flies that was widely introduced in the Americas to control pest species such as the Mediterranean fruit fly Ceratitis capitata. Augmentative releases in irrigated coffee plantations in semiarid regions of Brazil are under consideration and dispersal capacity of D. longicaudata in this habitat are important to develop release strategies. Approximately 2,000 individuals of D. longicaudata (5 to 7 days old were released in the center of a fruiting coffee plantation every two weeks from Dec. 2009 to Apr. 2010. Dispersal from the central release point was monitored to the north, south, east, west, northeast, northwest, southeast and southwest at 11 distances, beginning at 4.6 m and ending at 90 m from the release point. At each point, a parasitism unit (approximately 120 larvae of C. capitata in the 3rd instar wrapped in voile fabric and 10 coffee beans were collected. The average dispersion distance and dispersion area were estimated by the model proposed by Dobzhansky and Wright (1943. The average dispersion distances were 27.06 m (as estimated by fruit collection and 33.11 m (as estimated by oviposition traps. The average dispersion areas were 1,315.25 m2 and 1,752.45 m2 originating from the collection of beans and parasitism units, respectively. Cohorts of 2,000 adult D. longicaudata released at six points ha−1 are estimated to result in sufficient colonization to exert significant control of Ceratitis capitata.

    Gene transfer methodology for insects was first developed in Drosophila melanogaster Meigen using a transposon-mediated system based on the P element (Spradling and Rubin 1982, Rubin and Spradling 1982). In addition to the P element, three unrelated transposons have been used successfully in genetic transformation of D. melanogaster: hobo (Blackman et al. 1989), Minos (Loukeris et al. 1992), and mariner (Lidholm et al. 1993). Routine gene transfer in Drosophila created a great deal of optimism amongst researchers who sought to employ transgenic techniques in other arthropods. However, what followed were years of consistently disappointing results in other insect species. For example, the P element system was tried unsuccessfully in several species, but was eventually shown to be non-functional outside the genus Drosophila (O'Brochta and Handler 1988). Ensuing research in non-drosophilids emphasised testing of other Drosophila systems and development of transposons isolated from other species. After nearly 15 years of intensive effort, the first successes have only recently been reported. Three Drosophila-derived transposon-based systems: hobo from D. melanogaster, mariner from Drosophila mauritiana Tsacas and David and Minos from Drosophila hydei Sturtevant have produced germline transformation in Drosophila virilis Sturtevant (Gomez and Handler 1997, Lozovskaya et al. 1996), Aedes aegypti L. (Coates et al. 1998), and Ceratitis capitata (Wied.) (Loukeris et al. 1995), respectively. Germline transformation was accomplished with two transposon-based systems from non-drosophilids, Hermes from Musca domestica L. and piggyBac from Trichoplusia ni Huebner in A. aegypti and C. capitata, respectively

    Full Text Available Sugar-containing beverages are often seen as a negative influence on diet quality and body weight control. The present study examines the consumption of 100% fruit juice (FJ based on a seven-day dietary survey in a representative sample of French adults (n = 1607. About a half of the participants (44% consumed FJ, most often at breakfast time (60%. Average intake in FJ consumers was 115.6 ± 4.0 mL/day (46.3 ± 1.7 kcal/day. Prevalence of consumption increased with education and income and decreased with age, but no association was observed with body mass index (BMI, physical activity, or smoking. In consumers, FJ brought 2% daily energy and contributed larger proportions of vitamins (B1 7%, B2 3%, B5 5%, B6 6%, B9 10%, C 32%, E 9%, beta-carotene 5%, minerals (magnesium 4%, potassium 7%, and free sugars (19%. FJ consumers ingested more whole fruits, vegetables, and many other foods than non-consumers did. Free sugars represented 11.2% of the daily energy in FJ consumers versus 8.6% in non-consumers. This cross-sectional survey reveals that FJ contributes to diet quality without association with excess body weight. These observations should be confirmed in longitudinal studies. They support the view that contribution to diet quality should be specifically recognized in the context of the World Health Organization (WHO recommended decrease of free sugar intake.

    One of the best-studied diets for cardiovascular health is the Mediterranean diet. This consists of fish, monounsaturated fats from olive oil, fruits, vegetables, whole grains, legumes/nuts, and moderate alcohol consumption. The Mediterranean diet has been shown to reduce the burden, or even prevent the development, of cardiovascular disease, breast cancer, depression, colorectal cancer, diabetes, obesity, asthma, erectile dysfunction, and cognitive decline. This diet is also known to improve surrogates of cardiovascular disease, such as waist-to-hip ratio, lipids, and markers of inflammation, as well as primary cardiovascular disease outcomes such as death and events in both observational and randomized controlled trial data. These enhancements easily rival those seen with more established tools used to fight cardiovascular disease such as aspirin, beta-blockers, angiotensin-converting enzyme inhibitors, and exercise. However, it is unclear if the Mediterranean diet offers cardiovascular disease benefit from its individual constituents or in aggregate. Furthermore, the potential benefit of the Mediterranean diet or its components is not yet validated by concrete cardiovascular disease endpoints in randomized trials or observational studies. This review will focus on the effects of the whole and parts of the Mediterranean diet with regard to both population-based and experimental data highlighting cardiovascular disease morbidity or mortality and cardiovascular disease surrogates when hard outcomes are not available. Our synthesis will highlight the potential for the Mediterranean diet to act as a key player in cardiovascular disease prevention, and attempt to identify certain aspects of the diet that are particularly beneficial for cardioprotection.

    About 9% of the world's oil refining capacity is on the Mediterranean: some of the world's biggest and most advanced refineries are on Sicily and Sardinia. The Mediterranean refineries are important suppliers to southern Europe and N. Africa. The article discusses commercial refining in the Mediterranean under the headings of (i) historic development, (ii) product demand, (iii) refinery configurations, (iv) refined product trade, (v) financial performance and (vi) future outlook. Although some difficulties are foreseen, refining in the Mediterranean is likely to continue to be important well into the 21st century. (UK)

    This study evaluates the effectiveness of an intervention mapping developed to promote fruit and vegetable consumption. Students (n = 394) from two similar public colleges in the Quebec City area (Canada) were asked to participate. A quasi-experimental design was used with a 14-week pause between the pretest and posttest. The control and experimental groups both received information on Canada's Food Guide recommendations. The experimental group was submitted to an intervention consisting of six interactive workshops carried out inside the college, and three personal exercises to be completed at home. proportion of respondents consuming at least five servings of fruits and vegetables daily. psychosocial variables assessed (theory of planned behaviour). The data collected from 344 participants by means of a self-administered questionnaire were analysed (167 experimental and 177 control). The posttest revealed a significant increase (15%) in the number of participants in the experimental group achieving the primary outcome (d = .38). The intervention also had a significant effect on the targeted psychosocial variables (η(2) = .03 to .06). Regularity of consumption acts as a mediator between intention and behaviour. These results may be used to guide health promoters working with college students.

    Weight loss interventions have not been advocated for overweight/obese older adults due to potential loss of skeletal muscle and strength impacting on physical function with potential loss of independence. Carotenoids and polyphenols are inversely associated with sarcopenic symptomology. This paper reports the protocol of a study evaluating the efficacy of a high-protein, energy restricted diet rich in carotenoids and polyphenols on body composition, muscle strength, physical performance and quality of life in overweight and obese older adults. This randomised controlled clinical trial will recruit community-dwelling, healthy overweight and obese older adults (≥60 years) for a 12-week weight loss intervention. Seventy-three participants will be recruited and randomized to an energy restricted (~30% restriction), isocaloric diet (30% protein; 30% carbohydrate; 40% fat) enriched with either: a) 375 g/d of high carotenoid vegetables, 300 g/d high carotenoid fruit, and 40-60 ml extra-virgin olive oil (EVOO); or b) 375 g/d of lower carotenoid vegetables, 300 g/d lower carotenoid fruit, and 40-60 ml Polyunsaturated fatty acid (PUFA) based oil. All participants will receive individual dietary counselling each fortnight for the duration of the study and will be asked to maintain their habitual level of physical activity throughout the study. The primary outcome will be appendicular skeletal muscle (ASM) assessed by dual energy X-ray absorptiometry (DXA). Secondary outcomes will include body weight, fat-free mass (FFM), fat mass (FM), muscle strength (Isometric hand-grip strength), physical performance (Short Physical Performance Battery), physical activity (International Physical Activity Questionnaire) and health related quality of life (SF-36). Outcomes will be measured at baseline and at week 12. The results of this study will provide a novel insight relating to the potential influence of high carotenoid and polyphenol intakes on attenuation of ASM during

    Full Text Available Global food demand is increasing rapidly as a result of multiple drivers including population growth, dietary shifts and economic development. Meeting the rising global food demand will require expanding agricultural production and promoting healthier and more sustainable diets. The goal of this paper is to assess and compare the water footprint (WF of two recommended diets (Mediterranean and American, and evaluate the water savings of possible dietary shifts in two countries: Spain and the United States (US. Our results show that the American diet has a 29% higher WF in comparison with the Mediterranean, regardless of products’ origin. In the US, a shift to a Mediterranean diet would decrease the WF by 1629 L/person/day. Meanwhile, a shift towards an American diet in Spain will increase the WF by 1504 L/person/day. The largest share of the WF of both diets is always linked to green water (62%–75%. Grey water in the US is 67% higher in comparison with Spain. Only five products account for 36%–46% of the total WF of the two dietary options in both countries, being meat, oil and dairy products the food items with the largest WFs. Our study demonstrates that adopting diets based on a greater consumption of vegetables, fruits and fish, like the Mediterranean one, leads to major water savings.

    Full Text Available Myrtle is one of the important natural plant of the Mediterranean region. Fruits are in black and white colour. The earlier studies are mostly focused on the essential oil content of leaves in myrtle plant, whereas the latest studies are dealing with the phenolic compounds of leaves and fruits with their effects on human health. The aim of the study was to determine the phenolic content of the myrtle fruit and to investigate the differences between the genotypes. Myrtle fruits were collected from Antalya district. Phenolic content was determined by HPLC. Gallic acid (GA, catechin (CT, epicatechin (ECT, epicatechin-3-0-gallate (ECG, procyanidin B1 (B1, procyanidin B2 (B2, quercetin (Q, kamferol (K and myricetin (M were calculated as phenolic compounds. Epicatechin-3-0-gallate (in flavan-3-ol group and myricetin (in flavonol group were detected in large amounts.

    Full Text Available Substantial evidence supports the effect of the Mediterranean Diet (MD for managing chronic diseases, although trials have been primarily conducted in Mediterranean populations. The efficacy and feasibility of the Mediterranean dietary pattern for the management of chronic diseases has not been extensively evaluated in non-Mediterranean settings. This paper aims to describe the development of a MD model that complies with principles of the traditional MD applied in a multiethnic context. Optimal macronutrient and food-based composition was defined, and a two-week menu was devised incorporating traditional ingredients with evidence based on improvements in chronic disease management. Strategies were developed for the implementation of the diet model in a multiethnic population. Consistent with the principles of a traditional MD, the MD model was plant-based and high in dietary fat, predominantly monounsaturated fatty acids from extra virgin olive oil. Fruits, vegetables and wholegrains were a mainstay, and moderate amounts of nuts and seeds, fish, dairy and red wine were recommended. The diet encompassed key features of the MD including cuisine, biodiversity and sustainability. The MD model preserved traditional dietary components likely to elicit health benefits for individuals with chronic diseases, even with the adaptation to an Australian multiethnic population.

    Full Text Available The Mediterranean diet is characterized by high consumption of vegetables, fruits,  cereals, nuts, olive oil (rich in monounsaturated fatty acids, fish (rich in Omega - 3 fatty acids and moderate consumption of dry red wine. The positive impact of the diet on life expectancy and cardiovascular disease has been widely discussed, but further studies prove that it is also beneficial in supporting treatment of other civilization diseases such as diabetes, obesity, cancer, infertility and neurodegenerative or autoimmune diseases. Although certain studies on the effects of the Mediterranean diet still require further action, they undoubtedly give hope that the proper nutrition can have a significant impact on the prevention and treatment of civilization diseases.

    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

    Full Text Available The Mediterranean hake Merluccius merluccius L., 1758, is the emblem of the so-called Mediterranean demersal fisheries paradox, showing a persistent, although stable, status of growth overexploitation and an impressive gap between current and any biological reference point. Almost full avoidance capability of large size females to bottom trawls, higher overall growth rates than previously believed and higher natural mortality in juveniles than adult, were considered among the most plausible explanation factors of such persistence. In the present note, arguments are illustrated to raise some concern about avoidance and highlight the important role of the other factors in improving assessments and launching a short term recovery plan for Mediterranean Hake stocks which is more acceptable to fishermen.

    2018-01-01

    Globally, there is an increase in the older population, whose lives are affected by local cultural norms. In Eastern Mediterranean countries, dementia is conventionally hidden from view with few dedicated services or recognition for diagnosis. The aim of this systematic review is to explore the limited literature on dementia and cognitive impairment among older people in Eastern Mediterranean countries to present an evaluation of current practices and to consolidate knowledge for future planning. Thirty-three studies were identified for inclusion in the review, and four themes were apparent. Firstly, prevalence, comorbidity and gender: In Eastern Mediterranean countries, many studies identify that the prevalence of dementia is high. As is the case elsewhere, many older adults in Eastern Mediterranean countries have at least one coexisting long-term condition, and some experience low life-satisfaction. Secondly, culture: In Eastern Mediterranean countries, the older adult is highly respected, and placement outside of the family home is considered an abandonment of family duty. The term dementia carries stigma, and it is widely believed that dementia is caused by 'fate'. Thirdly, recognition and tools: There is a lack of verified assessment instruments to assess for dementia. Despite concerns about the cultural appropriateness of the Mini-Mental State Exam, particularly for people who have low literacy levels, and low literacy being the norm in Eastern Mediterranean countries, the Mini-Mental State Examination is the main assessment instrument. Translation and transition of non-Arabic assessment instruments and tools with psychometric properties presents a challenge for clinicians. Finally, workforce issues: health care workers lack knowledge about dementia, as dementia care is a relatively recent addition to the nursing and medical syllabi. While there were some inconsistencies in the papers published, many of the articles call for increasing educational programmes

    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.

  18. Mediterranean Way of Competitiveness

    Full Text Available The Mediterranean area have a special concept of competitiveness topic. Normally is that region not so industrial and knowledge based oriented as a North Europe.That countries can't reach the same development level as the north one. Lisbon's and Goethenburg's strategies create the main framework of development programme. Mediterranean programme is such a case. European internal market has forced the EU countries to increase competitiveness. The economic prosperity of countries is associated with their ability to generate or attract economic activities which are able to increase income by performing well on themarket. Financial crisis in the EU has changed the look on the competitiveness research. Economy in the main countries has to find way of recovery. Former giants of the financial world have found themselves suddenly facing bankruptcy.Inevitably, the crisis is also having an effect on households and businesses - economic growth has slowed sharply and in some EU countries unemployment has begun to increase for the first time in several years. Form that perspective we have to find the right solution of European competitiveness.

    2012-03-01

    There is a substantial body of evidence linking Mediterranean Diet to cardiovascular risk reduction and prevention of the major chronic diseases. Nevertheless Mediterranean societies are rapidly withdrawing from this eating pattern orienting their food choices toward products typical of the Western diet pattern, which is rich in refined grains, animal fats, sugars, processed meat but are quite poor in legumes, cereals, fruits and vegetables. The reasons people keep on shifting from healthy to unhealthy dietary habits remain open to several interpretations. Social changes appear to have consistently contributed to radical reversal in dietary habits in European Mediterranean societies even though developing Countries are somewhat turning into westernized diets as well. Among possible causes, increasing prices of some of the major food items of Mediterranean pyramid seem to have led people to give up this eating pattern in favor of less expensive products which allow to save money but are definitively unhealthy. Many studies suggest that diet quality follows a socio-economic gradient highlighting how disadvantaged people present higher rates of obesity, diabetes, cardiovascular disease and some types of cancer. Recent studies have shown a linear relationship between food cost and adherence to eating patterns and obesity. In addition to financial crisis, during the last decades the Mediterranean Diet has been put on the spot because of its alcohol -in- moderation component. Does it make any sense to blame a whole philosophy, which turned out to have beneficial effects on human health, just because, in some Countries, there is a misuse of alcoholic beverages?

    Full Text Available Abstract Background Lifestyle behaviours, such as healthy diet, physical activity and sedentary behaviour, are key elements of healthy ageing and important modifiable risk factors in the prevention of chronic diseases. Little is known about the relationship between these behaviours in older adults. The purpose of this study was to explore the relationship between fruit and vegetable (F&V intake, leisure-time physical activity (LTPA and sitting time (ST, and their association with self-rated health in older adults. Methods This cross-sectional study comprised 3,644 older adults (48% men aged 55–65 years, who participated in the Wellbeing, Eating and Exercise for a Long Life (“WELL” study. Respondents completed a postal survey about their health and their eating and physical activity behaviours in 2010 (38% response rate. Spearman’s coefficient (rho was used to evaluate the relationship between F&V intake, LTPA and ST. Their individual and shared associations with self-rated health were examined using ordinal logistic regression models, stratified by sex and adjusted for confounders (BMI, smoking, long-term illness and socio-demographic characteristics. Results The correlations between F&V intake, LTPA and ST were low. F&V intake and LTPA were positively associated with self-rated health. Each additional serving of F&V or MET-hour of LTPA were associated with approximately 10% higher likelihood of reporting health as good or better among women and men. The association between ST and self-rated health was not significant in the multivariate analysis. A significant interaction was found (ST*F&V intake. The effect of F&V intake on self-rated health increased with increasing ST in women, whereas the effect decreased with increasing ST in men. Conclusions This study contributes to the scarce literature related to lifestyle behaviours and their association with health indicators among older adults. The findings suggest that a modest increase

    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

    One hundred percent fruit juice (100% FJ) has been viewed by some as a sweetened beverage with concerns about its effect on weight. Little regard has been given to the contribution of 100% FJ to diet quality. In this study data from the 2003-2006 National Health and Nutrition Examination Survey were used to examine the association of 100% FJ consumption with diet quality in participants 2-5 years of age (y) (n = 1665), 6-12 y (n = 2446), 13-18 y (n = 3139), and 19+y (n = 8861). Two 24-hour dietary recalls were used to determine usual intake using the National Cancer Institute method. Usual intake, standard errors, and regression analyses (juice independent variable and Healthy Eating Index-2005 [HEI-2005] components were dependent variables), using appropriate covariates, were determined using sample weights. The percentage of participants 2-5 y, 6-12 y, 13-18 y, and 19+y that consumed 100% FJ was 71%, 57%, 45%, and 62%, respectively. Usual intake of 100% FJ (ounce [oz]/day) among the four age groups was: 5.8 ± 0.6, 2.6 ± 0.4, 3.7 ± 0.4, and 2.4 ± 0.2 for those in age groups 2-5 y, 6-12 y, 13-18 y, and 19+y, respectively. Consumption of 100% FJ was associated with higher energy intake in 6-12 y, 13-18 y, and 19+y; and higher total, saturated, and discretionary fats in 13-18 y participants. Consumption of 100% FJ was associated with higher total HEI-2005 scores in all age groups (diet quality in all age groups and should be encouraged in moderation as part of a healthy diet.

    Fruit flies of the family Tephritidae are considered the most important insect pest risk carried by exported fruits worldwide. Fruits suspected of harboring fruit fly eggs and larvae must be treated to control virtually 100% of any tephritids present. Irradiation is unique among quarantine treatments in that it is the only treatment used which does not cause acute mortality; instead, insects are prevented from maturing or are sterilized. Tephritids have been the most studied group of quarantined pests as far as irradiation; minimum absorbed doses confirmed with large-scale testing to provide control to the probit 9 level (99.9968%) have ranged from 50 to 250 Gy. Considerable work has been done with the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), one of the most important quarantined pests worldwide, and doses suggested to provide quarantine security have varied widely. The fact that insects are still alive for some time after irradiation has been one of the major obstacles to its use. Irradiation may be the most widely applicable quarantine treatment from the standpoint of fruit quality. However, some important fruits shipped across quarantine barriers (mangoes, Mangifera indica L., and citrus) may suffer from doses as low as 150 Gy when applied on a commercial scale where much of the fruit load may receive 300 Gy. Fortunately, some of the important tephritids attacking these fruits, such as Anastrepha spp., can be controlled with lower doses. Mainland USA has begun to use irradiation as a quarantine treatment for some fruits imported from Hawaii since April 1995 and remains the only country using irradiation as a quarantine treatment, although on a very limited basis. Irradiation offers some additional risk abatement advantages over other quarantine treatments. © 1999 Published by Elsevier Science B.V. All rights reserved. (author)

    Full Text Available Cancer prevention through food habits is an important matter of public health, given that everybody is exposed to food. The Mediterranean diet model is briefly reported, together with the way to evaluate the adherence to this diet. However, the original score, made for Mediterranean populations, had to be adapted to Western populations. These modifications pinpoint the peculiar aspects of the Mediterranean diet related to health. The studies reporting on the relationship between Mediterranean diet and cancer mortality, colorectal, breast, prostate and other cancers incidence are described. A risk reduction is generally evoked for these outcomes in Mediterranean countries, but it is more difficult to show in US or North-European country. Enough subjects with sane food habits, capable to reveal an inverse association of a Mediterranean-style diet and cancers, might only be found in large cohorts. In addition, the group of “negative” foods in the score needs to include “junk food”, known to be deleterious, and often part of the habits in these occidental countries. In conclusion, it can be said that a high and diverse consumption of fruits, vegetables, legumes, whole grain cereals is a must, be underlined the importance of olive oil, be mentioned the advantage of eating sea-food at least twice-a-week. Consumption of red and processed meat, dairy foods, and alcohol should be kept low and it is important to avoid sugars, saturated fats, all junk-foods, providing empty calories.

  10. Investigation of the effects of irradiation for quarantine treatment purposes on food quality and hygiene in citrus fruits

    International Nuclear Information System (INIS)

    2010-01-01

    Mediterranean fruit fly (Ceratitis capitata) is a major problem in citrus production sector in Turkey. In order to overcome this problem, required irradiation doses were investigated for the quarantine treatment for 'Yafa' orange (Citrus sinensis (L) Osb.), 'Star ruby' grapefruit (Citrus paradisi Macf.); 'Satsuma' tangerine (Citrus reticulata Blanco) in this project. Chemical, physical and microbiological properties of unirradiated and irradiated (0.5, 1.0 and 1.5 kGy) fruits were determined in terms of weight loss, water soluble dry matter, pH, titratable acidity, alcohol insoluble pectin, apparent color of fruits, reducing sugar, total carotenoid, flavonoid, vitamin C contents, sensory properties of fruits, total aerob mesophilic bacteria and total yeast and mould counts of fruits. Results showed that, 0.1 kGy gamma irradiation dose is sufficient for effective quarantine treatment against the Mediterranean fruit fly in citrus fruits, low dose irradiation (≤1.0 kGy) applications had no detrimental effects on citrus fruits' quality except tangerines, microbial load of fruits were seriously affected by irradiation at 1.0 kGy. In addition, under this work we noticed that, irradiated citrus fruits could be detected by using DNA comet analysis method.

    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).

    Poorer diets and subsequent higher rates of chronic disease among lower-income individuals may be partially attributed to reduced access to fresh fruits and vegetables (F&V) and other healthy foods. Mobile markets are an increasingly popular method for providing access to F&V in underserved communities, but evaluation efforts are limited. The purpose of this study was to determine the impact of Veggie Van (VV), a mobile produce market, on F&V intake in lower-income communities using a group randomized controlled trial. VV is a mobile produce market that sells reduced-cost locally grown produce and offers nutrition and cooking education. We recruited 12 sites in lower-income communities in North Carolina (USA) to host VV, randomizing them to receive VV immediately (intervention) or after the 6-month study period (delayed intervention control). Participants at each site completed baseline and follow-up surveys including F&V intake, perceived access to fresh F&V and self-efficacy for purchasing, preparing and eating F&V. We used multiple linear regression to calculate adjusted differences in outcomes while controlling for baseline values, education and clustering within site. Among 142 participants who completed the follow-up, baseline F&V intake was 3.48 cups/day for control and 3.33 for intervention. At follow-up, adjusted change in F&V consumption was 0.95 cups/day greater for intervention participants (p = 0.005), but was attenuated to 0.51 cups per day (p = 0.11) after removing extreme values. VV customers increased their F&V consumption by 0.41 cups/day (n = 30) compared to a 0.25 cups/day decrease for 111 non-customers (p = 0.04). Intervention participants did not show significant improvements in perceived access to fresh F&V, but increased their self-efficacy for working more F&V into snacks (p = 0.02), making up a vegetable dish with what they had on hand (p = 0.03), and cooking vegetables in a way that is appealing to their family (p

    Total alkalinity (AT) was measured during the Meteor 51/2 cruise, crossing the Mediterranean Sea from west to east. AT concentrations were high (∼2600 μmol kg−1) and alkalinity-salinity-correlations had negative intercepts. These results are explained by evaporation coupled with high freshwater AT inputs into coastal areas. Salinity adjustment of AT revealed excess alkalinity throughout the water column compared to mid-basin surface waters. Since Mediterranean waters are supersaturated with r...

    Full Text Available Numerous studies have demonstrated a relationship between Mediterranean Diet (MD adherence and the prevention of cardiovascular diseases, cancer, and diabetes, etc. The study aim was to validate a novel instrument to measure MD adherence based on the consumption of food servings and food groups, and apply it in a female population from southern Spain and determining influential factors.The study included 1,155 women aged 12-83 yrs, classified as adolescents, adults, and over-60-yr-olds. All completed a validated semi-quantitative food frequency questionnaire (FFQ. The Mediterranean Dietary Serving Score (MDSS is based on the latest update of the Mediterranean Diet Pyramid, using the recommended consumption frequency of foods and food groups; the MDSS ranges from 0 to 24. The discriminative power or correct subject classification capacity of the MDSS was analyzed with the Receiver Operating Characteristic (ROC curve, using the MDS as reference method. Predictive factors for higher MDSS adherence were determined with a logistic regression model, adjusting for age. According to ROC curve analysis, MDSS evidenced a significant discriminative capacity between adherents and non-adherents to the MD pattern (optimal cutoff point=13.50; sensitivity=74%; specificity=48%. The mean MDSS was 12.45 (2.69 and was significantly higher with older age (p<0.001. Logistic regression analysis showed highest MD adherence by over 60-year-olds with low BMI and no habit of eating between meals.The MDSS is an updated, easy, valid, and accurate instrument to assess MD adherence based on the consumption of foods and food groups per meal, day, and week. It may be useful in future nutritional education programs to prevent the early onset of chronic non-transmittable diseases in younger populations.

    The aim of the current study was to analyze the relationship between plant food (fruits, vegetables, and kimchi) and the prevalence of rhinitis among Korean adults using data from the 2011 and 2012 Korea National Health and Nutrition Examination Survey. A total of 7494 subjects aged from 19 to 64 years participated in a rhinitis morbidity survey, health behavior interview, and 24-h dietary recall test. Individuals with energy intakes less than 500 kcal or more than 5000 kcal were excluded. The results showed that kimchi intake was inversely associated with the prevalence of rhinitis. The prevalence of rhinitis decreased with increasing kimchi consumption. The quintile 4 (range of kimchi intake: 108.0-180.0 g) groups, compared with the reference of quintile 1 (0-23.7 g), showed a decrease of 18.9% (odds ratio [OR] = 0.811, 95% confidence interval [CI] = 0.672-0.979) in Model 4. In conclusion, consumption of kimchi lowers the risk of rhinitis, suggesting that its use should be encouraged among the Korean population.

    The aim of the present study was to determine the effect of fruit size on nutritional value, chemical composition and antioxidant properties of Mediterranean okra genotypes. For this purpose, pods from four okra cultivars and local landraces commonly cultivated in Greece, as well as pods from four commercial cultivars from North America were collected at two sizes (3-5 and>7cm). Significant differences were observed between the studied genotypes for both nutritional value and chemical composition parameters. Small fruit had a higher nutritional value, whereas chemical composition differed in a genotype dependent manner with most of the studied cultivars showing better results when harvested in small size. In conclusion, fruit size has a genotype dependent impact on chemical composition and nutritional value of okra pods and the common practice of harvesting okra fruit while they still have a small size helps to increase nutritional value for most of the studied genotypes.

    Larval and adult fruit flies are attracted to volatiles emanating from food substrates that have been occupied by larvae. We tested whether such volatiles are emitted by the larval gut bacteria by conducting tests under bacteria-free (axenic) conditions. We also tested attraction to two bacteria species, Lactobacillus brevis, which we cultured from larvae in our lab, and L. plantarum, a common constituent of fruit flies' microbiome in other laboratory populations and in wild fruit flies. Neither larvae nor adults showed attraction to axenic food that had been occupied by axenic larvae, but both showed the previously reported attraction to standard food that had been occupied by larvae with an intact microbiome. Larvae also showed significant attraction to volatiles from axenic food and larvae to which we added only either L. brevis or L. plantarum, and volatiles from L. brevis reared on its optimal growth medium. Controlled learning experiments indicated that larvae experienced with both standard and axenic used food do not perceive either as superior, while focal larvae experienced with simulated used food, which contains burrows, perceive it as superior to unused food. Our results suggest that flies rely on microbiome-derived volatiles for long-distance attraction to suitable food patches. Under natural settings, fruits often contain harmful fungi and bacteria, and both L. brevis and L. plantarum produce compounds that suppress the growth of some antagonistic fungi and bacteria. The larval microbiome volatiles may therefore lead prospective fruit flies towards substrates with a hospitable microbial environment.

    Few people on Prince Edward Island meet the goal of consuming five or more servings of vegetables and fruit a day. The main objective of this qualitative study was to explore the perceptions of the nutritional benefits and barriers to vegetable and fruit intake among adult women in Prince Edward Island. Participants were 40 women aged 20-49, with or without children at home, who were or were not currently meeting the objective of eating five or more fruit and vegetable servings a day. In-home, one-on-one interviews were used for data collection. Thematic analysis was conducted on the transcribed interviews. Data were examined for trustworthiness in the context of credibility, transferability, and dependability. Most participants identified one or more benefits of eating fruit and vegetables; however, comments tended to be non-specific. The main barriers that participants identified were effort, lack of knowledge, sociopsychological and socioenvironmental factors, and availability. Internal influences, life events, and food rules were identified as encouraging women to include vegetables and fruit in their diets. Given the challenges of effecting meaningful dietary change, dietitians must look for broader dietary behavioural interventions that are sensitive to women's perceptions of benefits and barriers to fruit and vegetable intake.

    Scientific evidence indicates that adherence to the Mediterranean diet protects against the deterioration of cognitive status and depressive symptoms during aging. However, few studies have been conducted in elderly non-institutionalized subjects. This study evaluated the relation between the adherence to the Mediterranean dietary pattern and cognitive status and depressive symptoms in an elderly population over 75 years. A cross-sectional study was conducted in a Mediterranean city (Garrucha, Spain) in 79 elderly people over 75 (36 men and 41 women). Adherence to the Mediterranean dietary pattern was determined using the Mediterranean Diet Adherence Screener (MEDAS). Cognitive function was determined by the Mini Mental State Examination (MMSE), and depressive symptoms were assessed by the Geriatric Depression Scale (GDS). Most of population showed a very high adherence to the Mediterranean diet pattern and optimal cognitive and affective status. They consumed olive oil as their main source of fat, high levels of fish and fruit, low levels of foods with added sugars, and a low consumption of red meat. A significant relation between the MEDAS and MMSE scores was found. However, no relationship was observed between the MEDAS and GDS. The Mediterranean diet pattern was positively related with the cognitive function, although the infl uence of a healthy dietary pattern on the symptomatology of depression was unclear. However, an effective strategy against cognitive function and depression would be to improve physical activity rates, establish lifelong healthy eating habits, and consume a nutritionally-rich diet in order to enhance quality of life of the elderly.

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

    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.

    More than 47,000 mature fruits of nine different varieties of rambutan (Nephelium lappaceum L.) were harvested from orchards in Hawaii to assess natural levels of infestation by tephritid fruit flies and other internal feeding pests. Additionally, harvested, mature fruits of seven different rambutan varieties were artificially infested with eggs or first-instars of Mediterranean fruit fly, Ceratitis capitata (Wiedemann), or oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) to assess host suitability. When all varieties were combined over two field seasons of sampling, fruit infestation rates were 0.021% for oriental fruit fly, 0.097% for Cryptophlebia spp. (Lepidoptera: Tortricidae), and 0.85% for pyralids (Lepidoptera). Species of Cryptophlebia included both C. illepida (Butler), the native Hawaiian species, and C. ombrodelta (Lower), an introduced species from Australia. Cryptophlebia spp. had not previously been known to attack rambutan. The pyralid infestation was mainly attributable to Cryptoblabes gnidiella (Milliere), a species also not previously recorded on rambutan in Hawaii. Overall infestation rate for other moths in the families Blastobasidae, Gracillariidae, Tineidae, and Tortricidae was 0.061%. In artificially infested fruits, both species of fruit fly showed moderately high survivorship for all varieties tested. Because rambutan has such low rates of infestation by oriental fruit fly and Cryptophlebia spp., the two primary internal-feeding regulatory pests of rambutan in Hawaii, it may be amenable to the alternative treatment efficacy approach to postharvest quarantine treatment.

    The Mediterranean dietary pattern, through a healthy profile of fat intake, low proportion of carbohydrate, low glycemic index, high content of dietary fiber, antioxidant compounds, and anti-inflammatory effects, reduces the risk of certain pathologies, such as cancer or Cardiovascular Disease (CVD). Nutritional adequacy is the comparison between the nutrient requirement and the intake of a certain individual or population. In population groups, the prevalence of nutrient inadequacy can be assessed by the probability approach or using the Estimated Average Requirement (EAR) cut-point method. However, dietary patterns can also be used as they have moderate to good validity to assess adequate intakes of some nutrients. The objective of this study was to review the available evidence on the Nutritional Adequacy of the Mediterranean Diet. The inclusion of foods typical of the Mediterranean diet and greater adherence to this healthy pattern was related to a better nutrient profile, both in children and adults, with a lower prevalence of individuals showing inadequate intakes of micronutrients. Therefore, the Mediterranean diet could be used in public health nutrition policies in order to prevent micronutrient deficiencies in the most vulnerable population groups. PMID:24394536

  9. An overview of quarantine for fruit flies

    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

    The aim of this work was to characterize food habits of Spanish University students and to assess the quality of their diet and some possible determinant factors according to Mediterranean food pattern among other indices. Two hundred eighty-four enrolled students during the academic year 2012-2013 participated in this survey. For each individual a questionnaire involving anthropometric measurements, types of housing, smoking habits and levels of physical activity were self-reported. Food consumption was gathered by two nonconsecutive 24 hour recalls including one weekend day. BMI within the normal range was showed by 72.5% of students and 75% of the sample reflected a sedentary lifestyle or low physical activity. The percentage of total energy from each macronutrient was approximately 17% proteins, 40% carbohydrates and 40% lipids. The ratio of polyunsaturated to monounsaturated fat only reached 0.32. Cholesterol consumption in men exceeded the intake in women by 70 mg/day but nutritional objectives were exceeded in both genders. The main source of protein had an animal origin from meat (38.1%), followed by cereals (19.4%) and dairy products (15.6%). The assessment of diet quality conducted by Healthy Eating Index (HEI) and Mediterranean Diet Score (MDS) revealed a low-intermediate score in both (51.2 ± 12.8 and 4.0 ± 1.5, respectively). The main deviations from Mediterranean pattern were a low intake of vegetables and fruit and a high consumption of meat and dairy products. According to HEI classification, 96.1% of subjects scored "poor" or "needs improvement" about the quality of their diet and only 5.3% of students achieved a high adherence to Mediterranean diet. It is necessary to foster changes toward a healthier diet pattern according to cultural context in this population for preventing cardiovascular diseases, type 2 diabetes and insulin resistance.

    Despite a common perception that fruit juice is healthy, fruit juice contains high amounts of naturally occurring sugar without the fibre content of the whole fruit. Frequent fruit juice consumption may therefore contribute to excessive sugar consumption typical of the Western society. Although excess sugar intake is associated with high blood pressure (BP), the association between habitual fruit juice consumption and BP is unclear. The present study investigated the association of fruit juice consumption with brachial and central (aortic) BP in 160 community dwelling adults. Habitual fruit juice consumption was measured using a 12 month dietary recall questionnaire. On the same day, brachial BP was measured and central (aortic) BP was estimated through radial artery applanation. Frequency of fruit juice consumption was classified as rare, occasional or daily. Those who consumed fruit juice daily, versus rarely or occasionally, had significantly higher central systolic BP (F (2, 134) = 6.09, p juice daily rather than rarely or occasionally. In conclusion, more frequent fruit juice consumption was associated with higher central BPs. Copyright © 2014 Elsevier Ltd. All rights reserved.

  16. Cosmologies of the ancient Mediterranean world

    John T. Fitzgerald

    2013-07-01

    Full Text Available Cosmology is concerned with the order of the universe and seeks to provide an account, not only of that order, but also of the mind or reason behind it. In antiquity, the cosmos was usually understood religiously, such that the cosmologies of the ancient Mediterranean world were either religious in nature or constituted a reaction to a religiously conceived understanding of the structures of the universe. The oldest form in which ancient cosmologies occur is myth, which, owing to its elasticity as a form, enabled them to be appropriated, adapted and used by different groups. In addition, different cosmologies co-existed within the same ancient culture, each having an authoritative status. This article provides an introductory overview of these cosmological myths and argues that a comparative approach is the most fruitful way to study them. Emphasis is given to certain prominent cosmological topics, including theogony (the genesis of the divine or the relationship of the divine to the cosmos, cosmogony (the genesis of the cosmos, and anthropogony (the origin of humans within the cosmos. Although these myths vary greatly in terms of content and how they envision the origin of the cosmos, many of them depict death as part of the structure of the universe.

    Two species of tephritid fruit flies of economic importance, Mediterranean fruit fly (Medfly, Ceratitis capitata [Wiedemann]) and Natal fruit fly (C. rosa Karsch) cause economic losses in the South African deciduous fruit industry of approximately US$3 million per annum. A third species, marula fruit fly, C. cosyra (Walker), causes damage to citrus and sub-tropical fruits in the north-eastern part of the country. In 1999 a sterile insect technique (SIT) programme against Medfly was initiated over 10,000 ha of table grapes with a goal of cost-effective, ecologically compatible suppression of Medfly. The SIT programme was extended to two other fruit production areas in 2004. Although results in all three SIT areas have been mixed, populations of wild Medflies, as well as associated pesticide usage and control costs, have been reduced since the start of sterile fly releases. Reasons for the partial degree of success and the relatively slow expansion of Medfly SIT to other areas include economic, operational and cultural factors, as well as certain fruit production practices. Before fruit fly-free areas can be created, deficiencies in the ability to mass-rear Natal fruit fly need to be overcome so that an SIT programme against this species can be initiated. Any fruit fly suppression or eradication campaign will be severely compromised by any introductions into South Africa of exotic fruit fly species. The risk of such introductions is increasing as trade with and travel to the country increases. A Plant Health Early Warning Systems Division has been initiated to formulate fruit fly detection and action plans. Melon fly (Bactrocera cucurbitae [Coquillett]), Asian fruit fly (B. invadens Drew, Tsurutu and White) and peach fruit fly (B. zonata [Saunders]), which are all well established in parts of Africa and/or Indian Ocean islands, have been identified as presenting the highest risk for entering and becoming established in South Africa.

    The Mediterranean is historically considered an area of high concentration of zoonoses. Mediterranean countries socio-economic features have favoured, over time, the onset of different types of zoonosis. Many of these may affect many occupational categories, first of all farmers, people working in abattoirs and processing products of animal origin. New farming activities and technologies have generated new occupational and zoonotic risks. These changes have influenced zoonosis epidemiology and have led to a gradual decrease in the number of diseases and to a reduction of some biological risks. However, brucellosis, Q fever, bovine tuberculosis cystic echinococcosis remain a strong example of zoonosis and a real risk, in the Mediterranean area especially. Therefore, an interdisciplinary collaboration between Veterinary Service, Public Health and Occupational medicine is necessary in order to plan territorial prevention.

  1. 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.

    In the coming years, European death rates because of cancer will further decline, but the overall number of cases will increase, mostly as a consequence of the ageing of the population. The target for cancer prevention in Europe will remain a healthy diet and control of obesity in addition to a decrease in smoking. A healthy diet model in European countries is the traditional Mediterranean diet, which is based on abundant and variable plant foods, high consumption of cereals, olive oil as the main (added) fat, low intake of (red) meat and moderate consumption of wine. The Mediterranean diet is associated with a reduced risk of cardiovascular disease and cancer. The biological mechanisms for cancer prevention associated with the Mediterranean diet have been related to the favourable effect of a balanced ratio of omega 6 and omega 3 essential fatty acids and high amounts of fibre, antioxidants and polyphenols found in fruit, vegetables, olive oil and wine. The Mediterranean diet also involves a 'Mediterranean way of drinking', that is, regular, moderate consumption of wine mainly with food. This pattern of drinking increases longevity, reduces the risk of cardiovascular disease and does not appreciably influence the overall risk of cancer. However, heavy alcohol drinking is associated with digestive, upper respiratory tract, liver and breast cancers; therefore, avoidance or restriction of alcohol consumption to two drinks/day in men and one drink/day in women is a global public health priority.

    Arbutus unedo is a small Mediterranean fruit, commonly named strawberry tree, which is a rich source of different sub-classes of phenolic compounds, the more representative being the gallic acid derivatives, including its mono and oligomeric forms esterified with quinic and shikimic acids. In addition, galloyl derivatives, particularly gallotannins, described in A. unedo, are part of a very selective phenolic group, present in a reduced number of plant-products. The aim of the present study is to provide a better understanding of human metabolic pathways of different sub-classes of phenols from the A. unedo fruit after an acute intake by healthy adults. Therefore, the A. unedo phenolic metabolites were studied in whole blood samples (0 to 24 h), urine (24 h) and feces (12 and 24 h). Special focus was placed on the application of dried blood spot (DBS) cards for the sample collection and for the analysis of phenolic metabolites in whole blood samples. The results of the blood analysis revealed two peaks for the maximum concentrations of the main phenolic metabolites. Furthermore, it is appropriate to highlight the application of DBS cards as an efficient and accurate way to collect blood samples in post-prandial bioavailability studies. The analysis of urine (24 h) gave a wide range of phenolic metabolites showing the extensive metabolism that A. unedo phenolic compounds underwent in the human body. The results of the study provide a relevant contribution to the understanding of the in vivo human bioavailability of phenolic compounds, especially galloyl derivatives, a singular phenolic sub-group present in the A. unedo fruit.

    Background: Adherence to a Mediterranean diet seems to be inversely associated with C-reactive protein (CRP) concentration. A 14-point Mediterranean Diet Adherence Screener (MEDAS) has been developed to assess dietary compliance. Objective: The aim of this study was to assess whether each of the MEDAS questions as well as their final score were associated with the levels of CRP in general Spanish population. Cross-sectional analysis of 1411 subjects (mean age 61 years, 43.0% males) randomly selected from the general population. CRP levels were determined by a commercial ELISA kit. Adherence to the Mediterranean diet was measured by the 14-point MEDAS. Results: There was an inverse correlation between adherence to the Mediterranean diet and the CRP concentration, even after adjusting by age, gender, hypertension, metabolic syndrome, body mass index, statin treatment and hypertension treatment ( p = 0.041). Subjects who consume ≥2 servings of vegetables per day ( p = 0.003), ≥3 pieces of fruit per day ( p = 0.003), ≥1 serving of butter, margarine, or cream per day ( p = 0.041) or ≥3 servings of fish/seafood per week ( p = 0.058) had significantly lower levels of CRP. Conclusions : Adherence to a Mediterranean-type diet measured by a simple questionnaire is associated with lower CRP concentration. However, this association seems to be particularly related to a higher consumption of vegetables, fruits, dairy products, and fish.

    Background Adherence to a Mediterranean diet may help prevent cognitive decline in older age, but studies are limited. We examined the association of adherence to the Mediterranean diet with cognitive function and decline. Methods We included 6,174 participants, aged 65+ years, from the cognitive sub-study of the Women’s Health Study. Women provided dietary information in 1998 and completed a cognitive battery 5 years later, followed by two assessments at 2-year intervals. The primary outcomes were composite scores of global cognition and verbal memory. The alternate Mediterranean diet adherence 9-point-score was constructed based on intakes of: vegetables, fruits, legumes, whole grains, nuts, fish, red and processed meats, moderate alcohol, and the ratio of monounsaturated-to-saturated fats. Results After multivariable adjustment, the alternate Mediterranean diet score was not associated with trajectories of repeated cognitive scores (P-trend across quintiles=0.26 and 0.40 for global cognition and verbal memory, respectively), nor with overall global cognition and verbal memory at older ages, assessed by averaging the three cognitive measures (P-trend=0.63 and 0.44, respectively). Among alternate Mediterranean diet components, higher monounsaturated-to-saturated fats ratio was associated with more favorable cognitive trajectories (P-trend=0.03 and 0.05 for global cognition and verbal memory, respectively). Greater whole grain intake was not associated with cognitive trajectories, but was related to better average global cognition (P-trend=0.02). Conclusions In this large study of older women, we observed no association of the Mediterranean diet with cognitive decline. Relations between individual Mediterranean diet components, particularly whole grains, and cognitive function merit further study. PMID:23676264

    Aim To assess the adherence to the Mediterranean diet in the population of Dalmatia in southern Croatia. Methods A cross-sectional study was performed within the 10 001 Dalmatians cohort, encompassing 2768 participants from Korčula and Vis islands and the City of Split, who were recruited during 2011-2014. Using the data obtained from food frequency questionnaire we calculated the Mediterranean Diet Serving Score (MDSS). Multivariate logistic regression was used to identify the characteristics associated with the adherence to the Mediterranean diet, with age, sex, place of residence, education attainment, smoking, and physical activity as covariates. Results The median MDSS score was 11 out of 24 points (interquartile range 8-13), with the highest score recorded on the island of Vis. Participants reported a dietary pattern that had high compliance with the Mediterranean diet guidelines for consumption of cereals (87% met the criteria), potatoes (73%), olive oil (69%), and fish (61%), moderate for consumption of fruit (54%) and vegetables (31%), and low for consumption of nuts (6%). Overall, only 23% of the participants were classified as being adherent to the Mediterranean diet, with a particularly low percentage among younger participants (12%) compared to the older ones (34%). Men were less likely to show good adherence (odds ratio 0.52, 95% confidence interval 0.42-0.65). Conclusion This study revealed rather poor compliance with the current recommendations on the Mediterranean diet composition in the population of Dalmatia. Public health intervention is especially needed in younger age groups and in men, who show the greatest departure from traditional Mediterranean diet and lifestyle. PMID:27815932

    Despite the existing evidence on the impact of olive oil and red wine on the intestinal microbiota, the effect of the global Mediterranean Diet (MD) has not been sufficiently studied. We explored the association between the adherence to a Mediterranean dietary pattern, and its components, with faecal microbiota in a cohort of adults with non-declared pathology. This transversal study involved 31 adults without a previous diagnosis of cancer, autoimmune or digestive diseases. Based on the data obtained by means of an annual food frequency questionnaire (FFQ), and the information existing in the literature, a Mediterranean Diet Score (MDS) was calculated. Dietary fibre was obtained from Marlett et al. tables and Phenol-Explorer Database was used for phenolic compounds intake. Quantification of microbial groups was performed by Ion Torrent 16S rRNA gene-based analysis and quantification of short-chain fatty acids (SCFAs) was performed using gas chromatography-mass spectrometry (MS). MDS was associated with a higher abundance of Bacteroidetes (p = 0.001), Prevotellacea (p = 0.002) and Prevotella (p = 0.003) and a lower concentration of Firmicutes (p = 0.003) and Lachnospiraceae (p = 0.045). Also, in subjects with MDS ≥ 4, higher concentrations of faecal propionate (p = 0.034) and butyrate (p = 0.018) were detected. These results confirm the complexity of the diet-microbiota interrelationship.

    Adherence to the Mediterranean diet is associated with lower mortality in a general population but limited evidence exists on the effect of a Mediterranean diet on mortality in subjects with diabetes. We aim to examine the association between the Mediterranean diet and mortality in diabetic individuals. Prospective cohort study on 1995 type 2 diabetic subjects recruited within the MOLI-SANI study. Food intake was recorded by the European Project Investigation into Cancer and Nutrition food frequency questionnaire. Adherence to the Mediterranean diet was appraised by the Greek Mediterranean diet score. Hazard ratios were calculated using multivariable Cox-proportional hazard models. During follow-up (median 4.0 years), 109 all-cause including 51 cardiovascular deaths occurred. A 2-unit increase in Mediterranean diet score was associated with 37% (19%-51%) lower overall mortality. Data remained unchanged when restricted to those being on a hypoglycaemic diet or on antidiabetic drug treatment. A similar reduction was observed when cardiovascular mortality only was considered (hazard ratio = 0.66; 0.46-0.95). A Mediterranean diet-like pattern, originated from principal factor analysis, indicated a reduced risk of overall death (hazard ratio = 0.81; 0.62-1.07). The effect of Mediterranean diet score was mainly contributed by moderate alcohol drinking (14.7% in the reduction of the effect), high intake of cereals (12.2%), vegetables (5.8%) and reduced consumption of dairy and meat products (13.4% and 3.4% respectively). The traditional Mediterranean diet was associated with reduced risk of both total and cardiovascular mortality in diabetic subjects, independently of the severity of the disease. Major contributions were offered by moderate alcohol intake, high consumption of cereals, fruits and nuts and reduced intake of dairy and meat products. © The European Society of Cardiology 2015.

  10. Implementing a Mediterranean-Style Diet Outside the Mediterranean Region.

    Populations surrounding the Mediterranean basin have traditionally reaped health benefits from a Mediterranean diet (MedDiet), which may benefit Westernized countries plagued by chronic disease. But is it feasible to implement beyond the Mediterranean? To answer this question, we present evidence from randomized controlled trials that achieved high dietary compliance rates with subsequent physical and mental health benefits. In the 1960s, the Seven Countries Study identified dietary qualities of Mediterranean populations associated with healthy aging and longevity. The PREDIMED study confirmed reductions in CVD-related mortality with a MedDiet; a meta-analysis in over 4.7 million people showed reduced mortality, CVD-related mortality, and reduced risk of Parkinson's and Alzheimer's disease. Continually emerging research supports the MedDiet's benefits for chronic diseases including metabolic syndrome, cancers, liver disease, type 2 diabetes, depression, and anxiety. We summarize components of studies outside the Mediterranean that achieved high compliance to a Med-style diet: dietitian led, dietary education, goal setting, mindfulness; recipe books, meal plans, and food checklists; food hampers; regular contact between volunteers and staff through regular cooking classes; clinic visits; and recipes that are simple, palatable, and affordable. The next step is testing the MedDiet's feasibility in the community. Potential obstacles include access to dietetic/health care professionals, high meat intake, pervasive processed foods, and fast food outlets. For Western countries to promote a Med-style diet, collective support from government, key stakeholders and policy makers, food industry, retailers, and health professionals is needed to ensure the healthiest choice is the easiest choice.

    This study compares postfire regeneration and diversity patterns in fire-prone chaparral shrublands from mediterranean (California) and non-mediterranean-type climates (Arizona). Vegetation sampling was conducted in tenth hectare plots with nested subplots for the first two years after fire. Floras in the two regions were compared with Jaccard's Index and importance of families and genera compared with dominance-diversity curves. Although there were 44 families in common between the two regions, the dominant families differed; Poaceae and Fabaceae in Arizona and Hydrophyllaceae and Rosaceae in California. Dominance diversity curves indicated in the first year a more equable distribution of families in Arizona than in California. Woody plants were much more dominant in the mediterranean climate and herbaceous plants more dominant in the bimodal rainfall climate. Species diversity was comparable in both regions at the lowest spatial scales but not at the tenth hectare scale. Due to the double growing season in the non-mediterranean region, the diversity for the first year comprised two different herbaceous floras in the fall and spring growing seasons. The Mediterranean climate in California, in contrast, had only a spring growing season and thus the total diversity for the first year was significantly greater in Arizona than in California for both annuals and herbaceous perennials. Chaparral in these two climate regimes share many dominant shrub species but the postfire communities are very different. Arizona chaparral has both a spring and fall growing season and these produce two very different postfire floras. When combined, the total annual diversity was substantially greater in Arizona chaparral.

    Full Text Available Myrtle (Myrtus communis L. is one of the medical and aromatic plants naturally grown in Mediterranean basin. Myrtle fruits are mostly consumed as fresh or dried while essential oils obtained from the leaves are widely used in pharmacy, perfumery, cosmetic and even as pesticide. Myrtle fruits have white and black color. Nowadays, there is a big demand for myrtle fruits because of its high antioxidant capacity. But it contains high amount of seeds which reduce marketing and production. Main objective of this study is to investigate the effects of GA3 on seedlesness and quality in black myrtle fruits. At different flowering stages, GA3 dose of 100 ppm were applied to whole of the plants. Some applications significantly reduced seed number in fruits. Two applications of GA3 at great ballon and full bloom stages consecutively decreased seed number from 10.69 (control to 1.98 seed fruit-1 . In addition, with three consecutive application of GA3, seed rate decreased to 4.98% while 15.08% in control. Some GA3 applications resulted in fully seedless fruits up to 10.67%. Conversely, GA3 applications did not change fruit weight and some biochemical parameters of fruits.

    The aim of the present review is to examine current scientific knowledge on the association between the Mediterranean diet and diabetes mellitus (mostly type 2 diabetes). A definition of the Mediterranean diet and the tools widely used to evaluate adherence to this traditional diet (Mediterranean diet indices) are briefly presented. The review focuses on epidemiological data linking adherence to the Mediterranean diet with the risk of diabetes development, as well as evidence from interventional studies assessing the effect of the Mediterranean diet on diabetes control and the management of diabetes-related complications. The above mentioned data are explored on the basis of evaluating the Mediterranean diet as a whole dietary pattern, rather than focusing on the effect of its individual components. Possible protective mechanisms of the Mediterranean diet against diabetes are also briefly discussed. PMID:24714352

    Dry fruits remain around the seeds at dispersal in a number of species, especially the Brassicaceae. Explanations for this vary, but usually involve mechanisms of innate dormancy. We speculate that, instead, a persistent fruit may give additional protection through control of dehydration, to species growing in arid or Mediterranean environments where water is sporadic. X-rays and weight measurements were used to determine the extent to which Raphanus raphanistrum seeds within mature fruits imbibe water, and germination tests determined the roles of the fruit and seed coat in seed dormancy. Rates of water uptake and desiccation, and seedling emergence were compared with and without the fruit. Finally, germinability of seeds extracted from fruits was determined after various periods of moist conditions followed by a range of dry conditions. Most seeds rapidly take up water within the fruit, but they do not fully imbibe when compared with naked seeds. The seed coat is more important than the dry fruit wall in maintaining seed dormancy. The presence of a dry fruit slows emergence from the soil by up to 6-8 weeks. The fruit slows the rate of desiccation of the seed to a limited extent. The presence of the fruit for a few days during imbibition somehow primes more seeds to germinate than if the fruit is absent; longer moist periods within the pod appear to induce dormancy. The fruit certainly modifies the seed environment as external conditions change between wet and dry, but not to a great extent. The major role seems to be: (a) the physical restriction of imbibition and germination; and (b) the release and then re-imposition of dormancy within the seed. The ecological significance of the results requires more research under field conditions.

    Full Text Available Mediterranean spotted fever is a tick-borne zoonotic disease caused by Rickettsia conorii. It is transmitted by the dog tick Rhipicephalus sanguineus. It usually presents as a benign self-limited disease characterized by a skin rash, high fever, and, sometimes, a characteristic ulcer at the tick bite site called tache noir. The course of this disease is usually benign, although severe manifestations have been previously described, mainly in adults. Neurological manifestations are very unusual. We present a case of Mediterranean spotted fever with encephalitis to highlight the importance of clinical suspicion, mainly in endemic areas, the potential severity of this disease, and the need of early initiation of therapy in order to prevent severe complications.

    The proposal of a Mediterranean way of life is much more than advise how to eat. The Mediterranean Diet, a model of Sustainable Diet, is an example of how to combine personal choices, economic, social and cultural rights, protective of human health and the ecosystem. There is in fact fundamental interdependence between dietary requirements, nutritional recommendations, production and consumption of food. In literature studies and nutritional and epidemiological monitoring activities at national and international level have found a lack of adherence to this lifestyle, due to the spread of the economy, lifestyles of the Western type and globalization of the production and consumption. To encourage the spread of a culture and a constant practice of the Mediterranean Diet, there are some tools that are presented in this article. The Mediterranean Diet Pyramid in addition to the recommendations on the frequency and portions of food, focuses on the choice of how to cook and eat food. The "Double Food Pyramid" encourages conscious food choices based on "healthy eating and sustainability. All the nutrition professionals and dietitians in particular should be constantly striving to encourage the adoption of a sustainable and balanced nutrition.

    The effects of diets high in refined grains on biliary and colonic bile acids have been investigated extensively. However, the effects of diets high in whole versus refined grains on circulating bile acids, which can influence glucose homeostasis and inflammation through activation of farnesoid X receptor (FXR) and G protein-coupled bile acid receptor 1 (TGR5), have not been studied. We conducted a secondary analysis from a randomized controlled crossover feeding trial (NCT00622661) in 80 healthy adults (40 women/40 men, age 18-45 years) from the greater Seattle Area, half of which were normal weight (BMI 18.5-25.0 kg/m 2 ) and half overweight to obese (BMI 28.0-39.9 kg/m 2 ). Participants consumed two four-week controlled diets in randomized order: 1) a whole grain diet (WG diet), designed to be low in glycemic load (GL), high in whole grains, legumes, and fruits and vegetables, and 2) a refined grain diet (RG diet), designed to be high GL, high in refined grains and added sugars, separated by a four-week washout period. Quantitative targeted analysis of 55 bile acid species in fasting plasma was performed using liquid chromatography tandem mass spectrometry. Concentrations of glucose, insulin, and CRP were measured in fasting serum. Linear mixed models were used to test the effects of diet on bile acid concentrations, and determine the association between plasma bile acid concentrations and HOMA-IR and CRP. Benjamini-Hochberg false discovery rate (FDR) < 0.05 was used to control for multiple testing. A total of 29 plasma bile acids were reliably detected and retained for analysis. Taurolithocholic acid (TLCA), taurocholic acid (TCA) and glycocholic acid (GCA) were statistically significantly higher after the WG compared to the RG diet (FDR < 0.05). There were no significant differences by BMI or sex. When evaluating the association of bile acids and HOMA-IR, GCA, taurochenodeoxycholic acid, ursodeoxycholic acid (UDCA), 5β-cholanic acid-3β,12

    Total fruit intake in the United States is ~1 cup equivalent per day, or one-half of the 2010 Dietary Guidelines for Americans recommendation for adults. Two-thirds of the fruit consumed is whole fruit and one-third is 100% juice. The nutritional value of whole fruit, with the exception of fiber and vitamin C, may be retained with appropriate juice production methods and storage conditions. One-hundred percent fruit juice consumption is associated with a number of health benefits, such as improved cardiovascular health and decreased obesity, although some of these and other potential benefits are controversial. Comprehensive analyses of the evidence by the Academy of Nutrition and Dietetics in 2014, the US Dietary Guidelines Advisory Committee in 2010, and the Australian Dietary Guidelines of 2013 concluded that 100% fruit juice is not related to adiposity in children when consumed in appropriate amounts for age and energy needs. However, some reports suggest the consumption of fruit juice contributes to unhealthful outcomes, particularly among children. A dietary modeling study on the best ways to meet the fruit intake shortfall showed that a combination of whole fruit and 100% juice improved dietary density of potassium and vitamin C without significantly increasing total calories. Notably, 100% juice intake was capped at amounts consistent with the 2001 American Pediatric Association guidance. The preponderance of evidence supports the position that 100% fruit juice delivers essential nutrients and phytonutrients, provides year-round access to a variety of fruits, and is a cost-effective way to help people meet fruit recommendations. © 2015 American Society for Nutrition.

    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 estimate the burden of undiagnosed celiac disease (CD) in the Mediterranean area in terms of morbidity, mortality and health cost. For statistics regarding the population of each country in the Mediterranean area, we accessed authoritative international sources (World Bank, World Health Organization and United Nations). The prevalence of CD was obtained for most countries from published reports. An overall prevalence rate of 1% cases/total population was finally estimated to represent the frequency of the disease in the area, since none of the available confidence intervals of the reported rates significantly excluded this rate. The distribution of symptoms and complications was obtained from reliable reports in the same cohort. A standardized mortality rate of 1.8 was obtained from recent reports. Crude health cost was estimated for the years between symptoms and diagnosis for adults and children, and was standardized for purchasing power parity to account for the different economic profiles amongst Mediterranean countries. In the next 10 years, the Mediterranean area will have about half a billion inhabitants, of which 120 million will be children. The projected number of CD diagnoses in 2020 is 5 million cases (1 million celiac children), with a relative increase of 11% compared to 2010. Based on the 2010 rate, there will be about 550,000 symptomatic adults and about 240,000 sick children: 85% of the symptomatic patients will suffer from gastrointestinal complaints, 40% are likely to have anemia, 30% will likely have osteopenia, 20% of children will have short stature, and 10% will have abnormal liver enzymes. The estimated standardized medical costs for symptomatic celiac patients during the delay between symptom onset and diagnosis (mean 6 years for adults, 2 years for children) will be about €4 billion (€387 million for children) over the next 10 years. A delay in diagnosis is expected to increase mortality: about 600,000 celiac patients will die in

    The analysis of burnt areas time series in Mediterranean regions suggests that ecosystems characterising this area consist primarily of species highly vulnerable to the fire but highly resilient, as characterized by a significant regenerative capacity after the fire spreading. In a few years the area burnt may once again be covered by the same vegetation present before the fire. Similarly, Mediterranean conifer forests, which often refers to plantations made in order to reforest the areas most severely degraded with high erosion risk, regenerate from seed after the fire resulting in high resilience to the fire as well. Only rarely, and usually with negligible damages, fire affects the areas covered by climax species in relation with altitude and soil types (i.e, quercus, fagus, abies). On the basis of these results, this paper shows how the simple Drossel-Schwabl forest fire model is able to reproduce the forest fire regime in terms of number of fires and burned area, describing whit good accuracy the actual fire perimeters. The original Drossel-Schwabl model has been slightly modified in this work by introducing two parameters (probability of propagation and regrowth) specific for each different class of vegetation cover. Using model selection methods based on AIC, the model with the optimal number of classes with different fire behaviour was selected. Two different case studies are presented in this work: Regione Liguria and Regione Sardegna (Italy). Both regions are situated in the center of the Mediterranean and are characterized by a high number of fires and burned area. However, the two regions have very different fire regimes. Sardinia is affected by the fire phenomenon only in summer whilst Liguria is affected by fires also in winter, with higher number of fires and larger burned area. In addition, the two region are very different in vegetation cover. The presence of Mediterranean conifers, (Pinus Pinaster, Pinus Nigra, Pinus halepensis) is quite spread in

    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

    The traditional Mediterranean diet (MD) is reportedly associated with lower risk of major chronic diseases and long considered to contribute to the reduced rates of cardiovascular and cerebrovascular events and to the highest life expectancy in adults who lived near the Mediterranean Sea. But despite its widely documented health benefits, adherence to this dietary pattern has been rapidly declining over the last decades due to a clear socioeconomic influence. The present review provides an overview of the evidence on the current major determinants of adherence to the Mediterranean diet, with a particular emphasis on Mediterranean Countries at a time of economic crisis; second it explores emerging socioeconomic inequalities in other domains of healthy dietary behaviours such as dietary variety, access to organic foods and food purchasing behaviour. According to ecological evidence, the Mediterranean Countries that used to have the highest adherence to the Mediterranean pattern in the Sixties, more recently experienced the greatest decrease, while Countries in Northern Europe and some other Countries around the world are currently embracing a Mediterranean-like dietary pattern. A potential cause of this downward trend could be the increasing prices of some food items of the Mediterranean diet pyramid. Recent evidence has shown a possible involvement of the economic crisis, material resources becoming strong determinants of the adherence to the MD just after the recession started in 2007-2008. Beyond intake, the MD also encourages increasing dietary diversity, while international dietary recommendations suggest replacing regular foods with healthier ones. Socioeconomic factors appear to be major determinants of the adherence to MD and disparities also hold for other indices of diet quality closely related to this dietary pattern.

    Four economically important fruit flies have been introduced accidentally into the Hawaiian Islands. They are the melon fly, Bactrocera cucurbitae (Coquillett) (introduced in 1895), the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (in 1907), the Oriental fruit fly, B. dorsalis (Hendel) (in 1945) and the Solanaceous fruit fly, B. latifrons (Hendel) (in 1983). These fruit flies jeopardise development of a diversified tropical fruit and vegetable industry in Hawaii, cause exported fruits to undergo expensive quarantine treatment and provide a reservoir for introduction into mainland United States. The establishment of fruit flies in Hawaii resulted in subsequent releases of numerous entomophagous insects. For example, Bess et al. (1961) listed a total of 32 natural enemies released between 1947 and 1952. Today, Fopius (=Biosteres) arisanus (Sonan), Diachasmimorpha longicaudata (Ashmead), Biosteres vandenboschi (Fullaway), Psyttalia incisi (Silvestri), Diachasmimorpha tryoni (Cameron) and Psyttalia fletcheri (Silvestri) are the most abundant species. These species have played a major role in the reduction of fruit flies throughout the Hawaiian Islands. For example, as a result of parasitisation (60-79.1%) by F. arisanus, the average number of Oriental fruit fly larvae per guava (Psidium guajava L.) fruit declined from 8.5 in 1950 to 2.6 in 1955 (Clausen et al. 1965). Demographic population analysis has diverse applications: analysing population stability and structure, estimating extinction probabilities, predicting life history evolution, predicting outbreaks in pest species and examining the dynamics of colonising or invading species. This study of the demography of Hawaiian fruit flies and their parasitoids is based on data from Vargas et al. (1984) and Vargas and Ramadan (1998). This paper describes the comparative demography of F. arisanus, B. tryoni, B. longicaudata, B. vandenboschi, P. incisi and P. fletcheri

    Racial and ethnic disparities in fruit and vegetable consumption have been widely studied in the USA. While previous studies focused on the differences of fruit and vegetable availability between racial groups, the equivalence of the association between consumption and availability across racial groups has been rarely examined. The purpose of this study was to investigate the relationship between availability of fruits and vegetables and their consumption across racial groups. The 2011-2012 California Health Interview Survey data (N = 36,302) were used for the study. Results of negative binomial regression show that the association between perceived availability of fruits and vegetables on consumption differs significantly between non-Hispanic Whites, Hispanics, Blacks, and Asians: (1) the association between fruit consumption and availability is only significant for non-Hispanic Whites (IRR = 1.303, 95 % CI 1.188, 1.429), and (2) the association between vegetable consumption and availability is only significant for non-Hispanic Whites (IRR = 1.242, 95 % CI 1.152, 1.340) and Hispanics (IRR = 1.141, 95 % CI 1.025, 1.271). This study highlights the importance of interventions that emphasize not only potential access but also social and cultural factors that relate to realized access to healthy food.

    Mediterranean diet is characterized by low to moderate consumption of animal protein and high consumption of fruits, vegetables, bread, beans, nuts, seeds and other cereals. It has been associated with reduced risk of cardiovascular disease. However, it is not suitable for chronic kidney disease because of high potassium intake. Tunisia is an emerging Mediterranean country with limited resources, a high prevalence of chronic hemodialysis treatment and high dialysis expenditures. In order to limit dialysis cost, primary and secondary prevention of chronic renal disease are of paramount importance. In addition to drugs, secondary prevention includes diet measures (e.g. salt diet, protein diet). The aims of diet practice in chronic kidney disease are to slow chronic renal failure progression and to prevent its complications like hyperphosphatemia and hyperkaliemiae. A few decades ago, a Tunisian diet was exclusively Mediterranean, and protein consumption was not excessive. However, today, protein consumption is more comparable to western countries. Salt consumption is also excessive. Some Tunisian diets still include food with high potassium intake, which are not suitable for patients with chronic kidney disease. Therefore, the role of the dietician is extremely important to help calculate and create a dietary regimen tailored to each of our patients. Advice about diets should be adapted to both the patient and population habits to improve adherence rate. As such, the purpose of this article is to provide our own experience regarding medical nutrition therapy in patients with chronic kidney disease in Tunisia, with some changes in food habits. Prevention is far better than treatment. In this perspective, dietary measures must be at the core of our intervention.

    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

    2016-10-01

    To investigate the evolution of the Mediterranean Diet (MD) in a delimited area of Southern Italy, by comparing the diet adopted 60-70 years ago (Prototypical Mediterranean Diet, PMD) with the contemporary one (Contemporary Mediterranean Diet, CMD), and to verify to what extent they fitted the recommendations of the Italian and the USDA dietary guidelines. We recruited a total of 106 participants, divided in two groups. PMD group included 52 women aged >80 years, with a good cognitive function and full independence in basic and instrumental activities of daily living. CMD group included 20 men and 34 women aged 50-60 years. Food intake was assessed by administering the EPIC food frequency questionnaire to each participant, and an additional survey to the PMD subjects only. Both PMD and CMD showed adequate intakes of macronutrients, although some deficiencies related to micronutrient requirements were evident. CMD showed a slightly greater use of animal products, processed and sugary foods, and higher intakes of simple sugars, animal proteins (49.6 vs 28.3 g/day), animal lipids (37.8 vs 20.1 g/day), saturated fats (25.0 vs 15.8 g/day) and cholesterol (305.0 vs 258.5 g/day). PMD showed many similarities to the original version of the MD in terms of macronutrients distribution and food choices. The documented evolution of the dietary habits over a 70 years timespan suggests that nowadays Mediterranean regions adhere less strictly to the original MD, although nutrients intakes are adequate to LARN and USDA recommendations.

    Full Text Available This study details mercury pollution within the food chain of the Mediterranean by analysing the most comprehensive mercury dataset available for biota and water measurements. In this study we computed a bioaccumulation factor (BAF for datasets in the existing mercury-related scientific literature, in on-going programs, and in past measurement campaigns. Preliminary results indicate a major lack of information, making the outcome of any assessment very uncertain. Importantly, not all marine eco-regions are (or have ever been covered by measurement campaigns. Most lacking is information associated with the South-Eastern part of the Mediterranean, and in several eco-regions it is still impossible to reconstruct a trophic net, as the required species were not accounted for when mercury measurements were taken. The datasets also have additional temporal sampling problems, as species were often not sampled systematically (but only sporadically during any given sampling period. Moreover, datasets composed of mercury concentrations in water also suffer from similar geographic limitations, as they are concentrated in the North-Western Mediterranean. Despite these concerns, we found a very clear bioaccumulation trend in 1999, the only year where comprehensive information on both methylmercury concentrations in water and biota was available.

    Malaysia is a tropical country that produces commercial fruits, including star fruits, Averrhoa carambola L. (Oxalidales: Oxalidaceae), and guavas, Psidium guajava L. (Myrtales: Myrtaceae). There is a high demand for these fruits, and they are planted for both local consumption and export purposes. Unfortunately, there has been a gradual reduction of these fruits, which has been shown to be related to fruit fly infestation, especially from the Bactrocera species. Most parasitic wasps (Hymenoptera: Braconidae: Opiinae) are known as parasitoids of fruit fly larvae. In this study, star fruits and guavas infested by fruit fry larvae were collected from the Malaysian Agricultural Research and Development Institute. The parasitized larvae were reared under laboratory conditions until the emergence of adult parasitoids. Multiplex PCR was performed to determine the braconid species using two mitochondrial DNA markers, namely cytochrome oxidase subunit I and cytochrome b. Two benefits of using multiplex PCR are the targeted bands can be amplified simultaneously using the same reaction and the identification process of the braconid species can be done accurately and rapidly. The species of fruit flies were confirmed using the COI marker. The results obtained from our study show that Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae), Fopius arisanus (Sonan), and Pysttalia incisi (Silvestri) were parasitoids associated with Bactrocera carambolae (Drew and Hancock) (Diptera: Tephritidae) infested star fruits. Fopius arisanus was also the parasitoid associated with Bactrocera papayae (Drew and Hancock) infested guavas. Maximum parsimony was been constructed in Opiinae species to compare tree resolution between these two genes in differentiating among closely related species. The confirmation of the relationship between braconids and fruit fly species is very important, recognized as preliminary data, and highly necessary in biological control programs. This is an

  8. Gaia and the Mediterranean Sea

    Directory of Open Access Journals (Sweden)

    Kenneth J. Hsü

    2001-12-01

    Full Text Available The Earth is a self-organizing system liking a living organism. Lovelock proposed Gaia as a metaphor to designate the check and balance ofterrestrial temperatures: the Earth is never too hot so that the ocean could boil, and the Earth is never too cold that the ocean could freeze from top to bottom. Hsü proposed that Gaia is endothermic because the life on Earth has been alternate successions of air-conditioners and heaters which evolved and deactivate or reinforce the terrestial greenhouse of carbon dioxide in atmosphere. When Earth was heating up too much, the air-conditioneers, such as anaerobic bacteria, cyanobacteria, skeletal organisms and trees, and finally calcareous plankton, went to work to bring the terrestrial temperature down. When the Earth was freezing at times of continental glaciation, heaters went to work, such as methanogenic bacteria, Ediacaran faunas, tundra and desert plants, and now Homo sapiens. Gaia has to have other organs to keep the self-organizing system vital. This paper presents a postulate that the Miocene Mediterranean Sea acted as Gaia´s kidney. The steady influx of dissolved ions and debris into the ocean causes inevitable increase of ocean´s salinity. The fossil and geochemicl records indicate that the ocean has never been too saline nor too brackish for the survival of normal marine organisms: the salinity ranged from about 32 to 36 pro mil during the last billion years. Ocean-drilling cruises to the Mediterranean discovered a very large salt formation, deposited during some 5 million years ago when the Mediterranean dried up. A study of the geochemical balance of the oceans indicates that the deposition of very large salt bodies in isolated basins such as the Miocene Mediterranean every 100 million years or so. The saline giants have the function of Gaia´s kidney. With periodical removals of the salt ions and the heavy metals from seawater, the world´s ocean have been rendered forever habitable. Gaia

    Large floral displays receive more pollinator visits but involve higher production and maintenance costs. This can result in indirect costs which may negatively affect functions like reproductive output. In this study, we explored the relationship between floral display and indirect costs in two pairs of coflowering sympatric Mediterranean Cistus of contrasting flower size. We hypothesized that: (1) corolla production entails direct costs in dry mass, N and P, (2) corollas entail significant indirect costs in terms of fruit set and seed production, (3) indirect costs increase with floral display, (4) indirect costs are greater in larger-flowered sympatric species, and (5) local climatic conditions influence indirect costs. We compared fruit set and seed production of petal-removed flowers and unmanipulated control flowers and evaluated the influence of mean flower number and mean flower size on relative fruit and seed gain of petal-removed and control flowers. Fruit set and seed production were significantly higher in petal-removed flowers in all the studied species. A positive relationship was found between relative fruit gain and mean individual flower size within species. In one pair of species, fruit gain was higher in the large-flowered species, as was the correlation between fruit gain and mean number of open flowers. In the other pair, the correlation between fruit gain and mean flower size was also higher in the large-flowered species. These results reveal that Mediterranean environments impose significant constraints on floral display, counteracting advantages of large flowers from the pollination point of view with increased indirect costs of such flowers.

    A single adult specimen of Gonioinfradens giardi, a portunid crab known from the Red Sea, Gulf of Oman and Arabian Gulf, was recently collected off the southern Israeli coast, in the southeastern Mediterranean Sea. Morphological characters, as well as molecular analyses based on the mitochondrial barcoding gene cytochrome oxidase sub unit I (COI), support its distinction from the widely distributed G. paucidentata. Therefore, G. giardi is reinstated as a valid species, and withdrawn from its synonymy with G. paucidentata. Previous Mediterranean records of the latter species are misidentifications and should be referred to G. giardi. The species is described, illustrated, and differentiated from its cogener.

    Even short-term adherence to a Mediterranean-style diet may benefit aspects of psychological functioning. The aim of the present study was to assess the effects of switching to a 10-d Mediterranean-style diet on mood, cognition, and cardiovascular measures. Using a crossover design, 24 women were randomly assigned to either the diet change (where they switched to a Mediterranean-style diet) or no diet change (normal diet) condition for 10 days before switching to the other condition for the same duration. Mood, cognition, and cardiovascular measures of blood pressure, blood flow velocity, and arterial stiffness were assessed at baseline and at the completion of the two diets (days 11 and 22). Independent of whether the Mediterranean-style diet was undertaken before or after the crossover, it was associated with significantly elevated contentment and alertness, and significantly reduced confusion. Additionally, aspects of cognition, such as memory recall, improved significantly as a result of switching to the Mediterranean-style diet. Regarding cardiovascular measures, there was a significant reduction in augmentation pressure associated with the Mediterranean-style diet intervention, but blood flow velocity through the common carotid artery did not change. This Mediterranean-style diet has the potential to enhance aspects of mood, cognition, and cardiovascular function in a young, healthy adult sample. Copyright © 2015 Elsevier Inc.

    A Mediterranean diet, known to have beneficial effects on cardiovascular health, may also influence the risk of hip fracture although previous studies present discrepant results. We therefore aimed to determine whether the rate of hip fracture was associated with degree of adherence to a Mediterranean diet. We combined two Swedish cohort studies consisting of 37,903 men and 33,403 women (total n = 71,333, mean age 60 years) free of previous cardiovascular disease and cancer who answered a medical and a food-frequency questionnaire in 1997. A modified Mediterranean diet score (mMED; range, 0 to 8 points) was created based on high consumption of fruits and vegetables, legumes and nuts, whole grains, fermented dairy products, fish, and olive/rapeseed oil, moderate intake of alcohol, and low intake of red and processed meat. Incident hip fractures between January 1, 1998, and December 31, 2012, were retrieved from the National Patient Register. Hazard ratios (HRs) and 95% confidence intervals (CIs) adjusted for potential confounders were calculated using Cox proportional hazards regression. Differences in age at hip fracture were calculated using multivariable Laplace regression. During follow-up, 3175 hip fractures occurred at a median age of 73.3 years. One unit increase in the mMED was associated with 6% lower hip fracture rate (adjusted HR = 0.94; 95% CI, 0.92 to 0.96) and with a 3-month higher median age at hip fracture (50th percentile difference = 2.8 months; 95% CI, 1.4 to 4.2). Comparing the highest quintile of adherence to the mMED (6 to 8 points) with the lowest (0 to 2 points) conferred an adjusted HR of hip fracture of 0.78 (95% CI, 0.69 to 0.89) and a 12-month higher median age of hip fracture (50th percentile difference = 11.6 months; 95% CI, 4.2 to 19.0). Results were similar in men and women. We conclude that higher adherence to a Mediterranean-like diet is associated with lower risk of future hip fracture. © 2016 American Society for

    Full Text Available The Mediterranean diet is rich in fruits and vegetables and has been associated with a variety of health benefits including cancer prevention. One aspect of the diet that has not received enough attention is Mediterranean herbs. Specifically, rosemary and its polyphenolic diterpenes (carnosic acid and carnosol are known to possess antioxidant activity that may be beneficial for cancer control. Herein, we describe the in vitro and in vivo studies carried out towards understanding the molecular mechanisms of carnosic acid and carnosol leading to inhibition of prostate cancer. The reported findings suggest that these polyphenols target multiple signaling pathways involved in cell cycle modulation and apoptosis. Further work is required to understand its potential for health promotion and potential drug discovery for prostate cancer chemoprevention.

    The Mediterranean Sea has been recently proposed as one of the most impacted regions of the world with regards to microplastics, however the polymeric composition of these floating particles is still largely unknown. Here we present the results of a large-scale survey of neustonic micro- and meso-plastics floating in Mediterranean waters, providing the first extensive characterization of their chemical identity as well as detailed information on their abundance and geographical distribution. All particles >700 μm collected in our samples were identified through FT-IR analysis (n = 4050 particles), shedding for the first time light on the polymeric diversity of this emerging pollutant. Sixteen different classes of synthetic materials were identified. Low-density polymers such as polyethylene and polypropylene were the most abundant compounds, followed by polyamides, plastic-based paints, polyvinyl chloride, polystyrene and polyvinyl alcohol. Less frequent polymers included polyethylene terephthalate, polyisoprene, poly(vinyl stearate), ethylene-vinyl acetate, polyepoxide, paraffin wax and polycaprolactone, a biodegradable polyester reported for the first time floating in off-shore waters. Geographical differences in sample composition were also observed, demonstrating sub-basin scale heterogeneity in plastics distribution and likely reflecting a complex interplay between pollution sources, sinks and residence times of different polymers at sea.

    To conduct a systematic review of the literature on prospective cohort studies examining associations between adherence to a Mediterranean diet and incident frailty and to perform a meta-analysis to synthesize the pooled risk estimates. Systematic review and meta-analysis. Embase, MEDLINE, CINAHL, PsycINFO, and Cochrane Library were systematically searched on September 14, 2017. We reviewed references of included studies and relevant review papers and performed forward citation tracking for additional studies. Corresponding authors were contacted for additional data necessary for a meta-analysis. Community-dwelling older adults (mean age ≥60). Incident frailty risk according to adherence to a Mediterranean diet. Two reviewers independently screened the title, abstract, and full text to ascertain the eligibility of 125 studies that the systematic search of the literature identified, and four studies were included (5,789 older people with mean follow-up of 3.9 years). Two reviewers extracted data from the studies independently. All four studies provided adjusted odds ratios (ORs) of incident frailty risk according to three Mediterranean diet score (MDS) groups (0-3, 4-5, and 6-9). Greater adherence to a Mediterranean diet was associated with significantly lower incident frailty risk (pooled OR = 0.62, 95% CI = 0.47-0.82, P = .001 for MDS 4-5; pooled OR = 0.44, 95% CI = 0.31-0.64, P Mediterranean diet is associated with significantly lower risk of incident frailty in community-dwelling older people. Future studies should confirm these findings and evaluate whether adherence to a Mediterranean diet can reduce the risk of frailty, including in non-Mediterranean populations. © 2018, Copyright the Authors Journal compilation © 2018, The American Geriatrics Society.

    Full Text Available Aristeus antennatus is an ecologically and economically important deep-water species in the Mediterranean Sea. In this study we investigated the genetic variability of A. antennatus sampled from 10 sampling stations in the Western and Central Mediterranean. By comparing our new samples with available data from the Western area, we aim to identify potential genetic stocks of A. antennatus and to reconstruct its historical demography in the Mediterranean. We analyzed two regions of mitochondrial DNA in 319 individuals, namely COI and 16S. We found two main results: i the genetic diversity values consistent with previous data within the Mediterranean and the absence of barriers to gene flow within the Mediterranean Sea; ii a constant long-term effective population size in almost all demes but a strong signature of population expansion in the pooled sample about 50,000 years B.P./ago. We propose two explanation for our results. The first is based on the ecology of A. antennatus. We suggest the existence of a complex meta-population structured into two layers: a deeper-dwelling stock, not affected by fishing, which preserves the pattern of historical demography; and genetically homogeneous demes inhabiting the fishing grounds. The larval dispersal, adult migration and continuous movements of individuals from "virgin" deeper grounds not affected by fishing to upper fishing areas support an effective 'rescue effect' contributing to the recovery of the exploited stocks and explain their genetic homogeneity throughout the Mediterranean Sea. The second is based on the reproduction model of this shrimp: the high variance in offspring production calls for a careful interpretation of the data observed under classical population genetics and Kingman's coalescent. In both cases, management policies for A. antennatus will therefore require careful evaluation of the meta-population dynamics of all stocks in the Mediterranean. In the future, it will be

    Although perennial fruit crops represent 1% of global agricultural land, they are of a great economic importance in world trade and in the economy of many regions. The perennial woody nature of fruit trees, their physiological stages of growth, the root distribution pattern, and the presence of herbaceous vegetation in alleys make orchard systems efficient in the use and recycling of nitrogen (N). The present paper intends to review the existing literature on N nutrition of young and mature deciduous and evergreen fruit trees with special emphasis to temperate and Mediterranean climates. There are two major sources of N contributing to vegetative tree growth and reproduction: root N uptake and internal N cycling. Optimisation of the use of external and internal N sources is important for a sustainable fruit production, as N use efficiency by young and mature fruit trees is generally lower than 55% and losses of fertilizer N may occur with the consequent economic and environmental concern. Organic alternatives to mineral N fertilizer like the application of manure, compost, mulching, and cover crops are scarcely used in perennial fruit trees, in spite of the fact that society's expectations call for more sustainable production techniques and the demand for organic fruits is increasing.

  4. Scenarios in the development of Mediterranean cyclones

    Full Text Available The Mediterranean is one of the most cyclogenetic regions in the world. The cyclones are concentrated along its northern coasts and their tracks are oriented more or less west-east, with several secondary tracks connecting them to Europe and to North Africa. The aim of this study is to examine scenarios in the development of Mediterranean cyclones, based on five selected winter seasons (October–March. We detected the cyclones subjectively using 6-hourly Sea-Level Pressure maps, based on the NCAR/NCEP reanalysis archive.

    HMSO (1962 has shown that most Mediterranean cyclones (58% enter the Mediterranean from the Atlantic Ocean (through Biscay and Gibraltar, and from the south-west, the Sahara Desert, while the rest are formed in the Mediterranean Basin itself. Our study revealed that only 13% of the cyclones entered the Mediterranean, while 87% were generated in the Mediterranean Basin. The entering cyclones originate in three different regions: the Sahara Desert (6%, the Atlantic Ocean (4%, and Western Europe (3%.

    The cyclones formed within the Mediterranean Basin were found to generate under the influence of external cyclonic systems, i.e. as "daughter cyclones" to "parent cyclones" or troughs. These parent systems are located in three regions: Europe (61%, North Africa and the Red Sea (34.5% and the Mediterranean Basin itself (4.5%. The study presents scenarios in the development of Mediterranean cyclones during the winter season, emphasizing the cyclogenesis under the influence of various external forcing.

    The large difference with respect to the findings of HMSO (1962 is partly explained by the dominance of spring cyclones generating in the Sahara Desert, especially in April and May that were not included in our study period.

  5. The role of the Strait of Gibraltar in shaping the genetic structure of the Mediterranean Grenadier, Coryphaenoides mediterraneus, between the Atlantic and Mediterranean Sea.

    Diana Catarino

    Full Text Available Population genetic studies of species inhabiting the deepest parts of the oceans are still scarce and only until recently we started to understand how oceanographic processes and topography affect dispersal and gene flow patterns. The aim of this study was to investigate the spatial population genetic structure of the bathyal bony fish Coryphaenoides mediterraneus, with a focus on the Atlantic-Mediterranean transition. We used nine nuclear microsatellites and the mitochondrial cytochrome c oxidase I gene from 6 different sampling areas. No population genetic structure was found within Mediterranean with both marker types (mean ΦST = 0.0960, FST = -0.0003, for both P > 0.05. However, within the Atlantic a contrasting pattern of genetic structure was found for the mtDNA and nuclear markers (mean ΦST = 0.2479, P 0.05. When comparing samples from Atlantic and Mediterranean they exhibited high and significant levels of genetic divergence (mean ΦST = 0.7171, FST = 0.0245, for both P < 0.001 regardless the genetic marker used. Furthermore, no shared haplotypes were found between Atlantic and Mediterranean populations. These results suggest very limited genetic exchange between Atlantic and Mediterranean populations of C. mediterraneus, likely due to the shallow bathymetry of the Strait of Gibraltar acting as a barrier to gene flow. This physical barrier not only prevents the direct interactions between the deep-living adults, but also must prevent interchange of pelagic early life stages between the two basins. According to Bayesian simulations it is likely that Atlantic and Mediterranean populations of C. mediterraneus were separated during the late Pleistocene, which is congruent with results for other deep-sea fish from the same region.

    To prospectively evaluate the association of the Mediterranean-DASH diet intervention for neurodegenerative delay (MIND) diet and the Mediterranean diet (and their components), and depression risk. We followed-up (median 10.4 years) 15,980 adults initially free of depression at baseline or in the first 2 years of follow-up. Food consumption was measured at baseline through a validated food-frequency questionnaire, and was used to compute adherence to the MIND and the Mediterranean diets. Relationships between these two diets and incident depression were assessed through Cox regression models. We identified 666 cases of incident depression. Comparing the highest versus the lowest quartiles of adherence, we found no association of the MIND diet and incident depression. This relation was statistically significant for the Mediterranean diet {hazard ratio (HR) 0.75, [95% confidence interval (95% CI) 0.61, 0.94]; p Mediterranean diet was associated with reduced depression risk, but we found no evidence of such an association for the MIND diet.

    Metabolic syndrome (MS) has a multifactorial and not yet fully clarified origin. Insulin resistance is a key element that connects all the accepted components of MS (obesity, dyslipemia, high blood pressure, and hyperglycemia). There is strong evidence that epigenetic changes during fetal development are key factors in the development of MS. These changes are induced by maternal nutrition, among different factors, affecting the intrauterine environment. The Mediterranean diet has been shown to be a healthy eating pattern that protects against the development of MS in adults. Similarly, the Mediterranean diet could have a similar action during pregnancy, protecting the fetus against the development of MS throughout life. This review assembles studies carried out, both in animals and humans, on the epigenetic modifications associated with the consumption, during pregnancy, of Mediterranean diet main components. The relationship between these modifications and the occurrence of factors involved in development of MS is also explained. In addition, the results of our group relating adherence to the Mediterranean diet with MS markers are discussed. The paper ends suggesting future actuation lines in order to increase knowledge on Mediterranean diet adherence as a prevention tool of MS development.

    The Mediterranean Sea represents only about 0.7% of the planet's total water surface area, yet it is host to as much as one-quarter of the world's total maritime oil traffic. Statistics indicate that from 47 to 77,000 tonnes of crude oil are now being released annually into the Sea through accidental spills; and over the last decade, its tourism dependent coastlines have been fouled by the highest levels of tar contamination in the world. Oil carrier traffic, routed within the Sea's already overcrowded shipping lanes, is intense and this traffic is expected to increase, as a result of rises in world energy demand, to levels of from 7 to 8 million barrels a day. It has been estimated that, at the end of 1992, 90% of all large tankers operating in this area, will have reached a service life of 15-16 years which is very close to the average recommended life cycle limit of 15-20 years. Only 20% of the world's 3,000 tankers are currently equipped with double bottomed hulls. This paper uses these and other facts and figures to argue that the risks of future severe oil tanker accidents in the Mediterranean Sea are high, and that these must be countered with the development of a new set of stricter marine traffic safety regulations at the Italian, national, as well as, European level

    United Nations Environmental Program (UNEP) studies on forecasted greenhouse climatic effects on the Mediterranean coastal and marine ecosystems and regional socio-economic framework have indicated the need for a concerted plan of protective and remedial action. The studies considered rises of 1.5 degrees in ambient temperature and 20 centimeters in sea level occurring before the year 2025. A regional, as opposed to a global area, study approach was adopted since the severity of climatic effects is expected to vary greatly from one part of the world to another. The specific areas investigated were the Po River Delta and Venezia Lagoon in Italy, the Nile Delta, Camargue, the Ebro Delta, the Tunisian National Park area, and the Thermaicos Gulf in Greece. The rise in average temperature is expected to negatively effect Mediterranean agricultural production and the coastal and marine ecosystems due to prolonged periods of drought and exceptional rainfall. It is suggested that a system of dikes be constructed to protect the coastal areas which are heavily dependent on tourism and agriculture

    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

  14. Cosmologies of the ancient Mediterranean world

    John T. Fitzgerald

    2013-07-01

    Full Text Available Cosmology is concerned with the order of the universe and seeks to provide an account, not only of that order, but also of the mind or reason behind it. In antiquity, the cosmos was usually understood religiously, such that the cosmologies of the ancient Mediterranean world were either religious in nature or constituted a reaction to a religiously conceived understanding of the structures of the universe. The oldest form in which ancient cosmologies occur is myth, which, owing to its elasticity as a form, enabled them to be appropriated, adapted and used by different groups. In addition, different cosmologies co-existed within the same ancient culture, each having an authoritative status. This article provides an introductory overview of these cosmological myths and argues that a comparative approach is the most fruitful way to study them. Emphasis is given to certain prominent cosmological topics, including theogony (the genesis of the divine or the relationship of the divine to the cosmos, cosmogony (the genesis of the cosmos, and anthropogony (the origin of humans within the cosmos. Although these myths vary greatly in terms of content and how they envision the origin of the cosmos, many of them depict death as part of the structure of the universe. Kosmologie het te doen met die orde van die heelal en wil rekenskap gee van hierdie orde en ook van die bewussyn daaragter. In die antieke tyd is die kosmos gewoonlik godsdienstig verstaan, met die gevolg dat die kosmologieë van die antieke Mediterreense wêreld óf ’n godsdienstige aard gehad het óf bestaan het uit ’n reaksie op ’n godsdienstig-geskepte begrip van die strukture van die heelal. Mites was die oudste vorm waarin antieke kosmologieë voorkom wat vanweë hulle plooibaarheid dit bewerk het dat hierdie kosmologieë deur verskillende groepe toegeëien, aangepas en gebruik kon word. Hierbenewens het verskillende kosmologieë in die antieke kultuur langs mekaar bestaan – elkeen

    Economic losses in a range of fruit crops due to the Drosophila suzukii (Matsumura) have become severe. Removal and treatment of fruit waste, which may harbor D. suzukii, is a key step in preventing reinfestation of fruit production. Natural fermentation for disinfesting fruit wastes from D. suzukii was examined at ambient air temperatures of 12-20 °C. Soft and stone fruit wastes infested with eggs, larvae, and pupae of Drosophila melanogaster (Meigen) or D. suzukii were placed in sealed vessels containing fruit wastes, and samples were retrieved at intervals and tested for the emergence of adults. Mean temperatures of the fruit waste in the sealed vessels during fermentation were 15-23 °C. Fermentation for 3 d was effective in disinfesting waste from different life stages of D. suzukii. Treatment for 4 d also ensured that the waste was free of viable life stages of D. melanogaster, which could be used as an indicator species for disinfestation of waste from D. suzukii owing to its greater tolerance of fermentation. The O2 concentration of the headspace air in the vessels became undetectable after 13-16 h, with a corresponding increase in CO2 concentration, which exceeded 80% vol/vol. The resulting hypoxia and hypercapnia may explain the efficacy of the fermentation treatment in disinfesting the waste. Fermented fruit remained attractive to D. suzukii and retained its capacity to rear a life cycle. Covering or mixing fermented fruit with a sufficient depth (0.1 m) or volume (×9) of soil or coir prevented the reinfestation of treated waste. © The Authors 2017.

    Coastal lagoons, both hypersaline and freshwater, are common, but still understudied ecosystems. We describe, for the first time, using high throughput sequencing, the extant microbiota of two large and representative Mediterranean coastal lagoons, the hypersaline Mar Menor, and the freshwater Albufera de Valencia, both located on the south eastern coast of Spain. We show there are considerable differences in the microbiota of both lagoons, in comparison to other marine and freshwater habitats. Importantly, a novel uncultured sulfur oxidizing Alphaproteobacteria was found to dominate bacterioplankton in the hypersaline Mar Menor. Also, in the latter prokaryotic cyanobacteria were almost exclusively comprised by Synechococcus and no Prochlorococcus was found. Remarkably, the microbial community in the freshwaters of the hypertrophic Albufera was completely in contrast to known freshwater systems, in that there was a near absence of well known and cosmopolitan groups of ultramicrobacteria namely Low GC Actinobacteria and the LD12 lineage of Alphaproteobacteria.

    Diseases evolve constantly and research is needed to face emerging new threats. Evidences suggest that the impact of such threats will have its peak in the Mediterranean area. The FORE‑Med, Foresight project for the Mediterranean, aims at identifying the future challenges on livestock health and aquaculture in this area, to ensure an effective coordination of research activities and the delivery of timely solution to emerging issues. One hundred experts with multidisciplinary background and coming from countries all around the Mediterranean basin were gathered to participate in a think‑tank to develop a Strategic Research Agenda on animal health for Mediterranean up to 2030. A tailored foresight methodology was implemented, merging the best fit for purpose techniques (e.g. '7 questions', Social, Technological, Economical, Environmental, and Political (STEEP), analysis, scenario building, and backcasting). Both remote and face‑to‑face debates were held, to ensure a fruitful exchanges and participation among experts. Research needs were identified and prioritised, both on relevance and on temporal scale. The implemented participative approach allowed for the definition of a research priority list for animal health and aquaculture in the Mediterranean, which served as a basis to build a strategic research agenda. The latter is expected to satisfy the sectors' needs and guarantee a much‑needed coordination for research activities in the Mediterranean area.

    Substantial evidence has verified the Mediterranean diet's (MedDiet) nutritional adequacy, long-term sustainability, and effectiveness for preventing hard clinical events from cardiovascular disease (CVD), as well as increasing longevity. This article includes a cumulative meta-analysis of prospective studies supporting a strong inverse association between closer adherence to the MedDiet and the incidence of hard clinical events of CVD. The MedDiet has become an increasingly popular topic of interest when focusing on overall food patterns rather than single nutrient intake, not only in Mediterranean countries, but also globally. However, several myths and misconceptions associated with the traditional Mediterranean diet should be clearly addressed and dispelled, particularly those that label as "Mediterranean" an eating pattern that is not in line with the traditional Mediterranean diet. The transferability of the traditional MedDiet to the non-Mediterranean populations is possible, but it requires a multitude of changes in dietary habits. New approaches for promoting healthy dietary behavior consistent with the MedDiet will offer healthful, sustainable, and practical strategies at all levels of public health. The following article presents practical resources and knowledge necessary for accomplishing these changes.

    The objective of this study was to evaluate the fruit fly infestation on coffee and citrus, and also to determine gamma radiation doses for immature stages of Ceratitis capitata and Anastrepha fraterculus, in order to satisfy quarantine regulations. Coffee arabica varieties Icatu Vermelho, Catuai Amarelo, Mundo Novo and Sarchimor showed the highest infestation indices (pupa/berry): 0.53; 0,41; 0.33 and 0.36. respectively Icatu Vermelho and Catuai Vermelho showed the highest values of pupa/berry weight (0.49 and 0.39, respectively), and Robusta (Coffea canephora) presented the lowest index (0.01). The following fruit flies were found in coffee berries: C. capitata (76.6%) Anastrepha spp. (7.4%) and Lonchaeidae (17.0%). In area near coffee plantation, fruit fly infestation indices in sweet oranges were of 4.77 larvae/kg and 0.55 larva/fruit. The infestation indices for sweet orange, collected from five regions of the State of Sao Paulo ranged from 0.73 to 7.60 pupa/kg and 0.12 to 1.27 pupa/fruit. The same species of fruit flies were found in oranges. In the case of C. capitata eggs with 24-48 hours old, 20 Gy prevented completely adult emergence (artificial diet and orange). No emergence of adult occurred when C. capitata larvae of third instar were irradiated at 20 Gy in their rearing medium. But at 25 Gy, the number of adults was reduced by 54% and 97% from larval infestation in oranges and grapefruit, respectively. A dose of 30 Gy was required to prevent medfly emergence from third instar larvae in grapefruit. A dose of 15 Gy was required for third instar, to prevent adult emergence of A. fraterculus. No adult emerged from C third instar, to prevent adult emergence of A. fraterculus. No adult emerged from C capitata pre-pupa irradiated at 30 Gy. One medfly adult emerged from pupa (3-4 days after pupating) irradiated at 120 Gy. At the same dose, sixteen A. fraterculus adults emergency from irradiated pupa with 5-6 days old. (author)

    In being at the base of the marine food web, phytoplankton is particularly important for marine ecosystem functioning (e.g., biodiversity). Strong anthropization, over-exploitation of natural resources, and climate change affect the natural amount of phytoplankton and, therefore, represent a continuous threat to the biodiversity in marine waters. In particular, a concerning risks for coastal waters is the increase in nutrient inputs of terrestrial/anthropogenic origin that can lead to undesirable modifications of phytoplankton concentration (i.e., eutrophication). Monitoring chlorophyll (Chl) concentration, which is a proxy of phytoplankton biomass, is an efficient tool for recording and understanding the response of the marine ecosystem to human pressures and thus for detecting eutrophication. Here, we compute Chl trends over the Mediterranean Sea by using satellite data, also highlighting the fact that remote sensing may represent an efficient and reliable solution to synoptically control the "good environmental status" (i.e., the Marine Directive to achieve Good Environmental Status of EU marine waters by 2020) and to assess the application of international regulations and environmental directives. Our methodology includes the use of an ad hoc regional (i.e., Mediterranean) algorithm for Chl concentration retrieval, also accounting for the difference between offshore (i.e., Case I) and coastal (i.e., Case II) waters. We apply the Mann-Kendall test and the Sens's method for trend estimation to the Chl concentration de-seasonalized monthly time series, as obtained from the X-11 technique. We also provide a preliminary analysis of some particular trends by evaluating their associated inter-annual variability. The high spatial resolution of our approach allows a clear identification of intense trends in those coastal waters that are affected by river outflows. We do not attempt to attribute the observed trends to specific anthropogenic events. However, the trends

Our methodology includes the use of an ad hoc regional (i.e., Mediterranean algorithm for Chl concentration retrieval, also accounting for the difference between offshore (i.e., Case I and coastal (i.e., Case II waters. We apply the Mann-Kendall test and the Sens's method for trend estimation to the Chl concentration de-seasonalized monthly time series, as obtained from the X-11 technique. We also provide a preliminary analysis of some particular trends by evaluating their associated inter-annual variability. The high spatial resolution of our approach allows a clear identification of intense trends in those coastal waters that are affected by river outflows. We do not attempt to attribute the observed trends to specific anthropogenic events. However
