Full Text Available Abstract Parasitic diseases reflect the health and balance of ecosystems, affecting not only individuals but also entire populations or communities. The aim of this study was to report on the diversity of parasitic helminths detected in the feces of a wild feline in southern Brazil. Parasites were obtained from fecal samples, and four techniques were used for parasitological examination: direct examination, centrifugal flotation with zinc sulfate (Faust technique, simple sedimentation (Hoffman technique and Baermann-Moraes. The parasites were identified through micrometry and morphology, as follows: Ancylostoma sp., Toxocara sp., Trichuridae, Aelurostrongylus abstrusus, Alaria sp., and Spirometra sp. We recorded the genus Ancylostoma parasitizing L. colocolo for the first time.

The present study is the first to show overall prevalences of intestinal parasites among breeding kennel dogs in Japan. A total of 573 fresh fecal samples were collected from dogs at 12 breeding kennels. Giardia-specific coproantigen was examined by ELISA kit (SNAP(®) Giardia, IDEXX Laboratories, Inc., Maine, USA). Other intestinal parasites were determined microscopically using the formalin-ethyl acetate sedimentation technique. Overall prevalences of two genera of protists, Giardia spp. and Cystoisospora spp., were 25.7 and 1.2 %, respectively. The prevalence of helminthes was recorded as: Toxocara canis 0.2 %, Toxascaris leonina 0.9 %, Ancylostoma caninum 0.2 %, Trichuris vulpis 2.1 %, and Spirometra erinacei 0.4 %. According to age categories, Giardia spp., Cystoisospora spp., and T. leonina in parasite infections were found at the high prevalent, ranging from 16.0 to 70.0 %.

Full Text Available Vos, Faust, Voss: Points of contact between Vos by Anna M. Louw and selected other texts This article explores points of contact between “Vos” by Anna M. Louw and a number of related texts, including the following: the book “Job” from the Christian Bible, “Faust” by Goethe, “Voss” by Patrick White and texts forming part of the Gnostic tradition. The analysis describes similarities and differences, arguing that the implication of the points of contact between the various texts is that Vos suggests that the heritage of the Christian Reformation is not adequate for an understanding of life in South Africa, and it has to be supplemented with perspectives from other traditions.

2013-09-01

Full Text Available Background: Sparganosis is caused by the invasion of Spirometra sparganum into various tissues/organs. Subcutaneous sparganosis can be diagnosed by biopsy, while visceral/cerebral sparganosis is not easy to be diagnosed. The diagnosis de­pends largely on the detection of specific anti-sparganum antibodies. The specific­ity of the ELISA could be increased by using S. mansoni sparganum excretory–secre­tory (ES antigens, but it also had the cross-reactions with sera of patients with cysticercosis or paragonimiasis. The aim of this study was to identify early specific diagnostic antigens in S. mansoni sparganum ES proteins.Methods: The sparganum ES proteins were analyzed by two-dimensional electrophore­sis (2-DE and Western blot probed with early sera from infected mice at 14 days post-infection. The immunoreactive protein spots were characterized by MALDI-TOF/ TOF-MS.Results: A total of approximately 149 proteins spots were detected with isoelectric point (pI varying from 3 to 7.5 and molecular weight from 20 to 115 kDa and seven protein spots with molecular weight of 23-31 kDa were recognized by the infection sera. Three of seven spots were successfully identified and characterized as the same S. mansoni protein (cysteine protease, and the proteins of other 4 spots were not included in the databases.Conclusion: The cysteine protease from S. mansoni ES proteins recognized by early infection sera might be the early diagnostic antigens for sparganosis.

Self-focusing and defect characterization with the FAUST system

International Nuclear Information System (INIS)

Mahaut, S.; Cattiaux, G.; Roy, O.; Benoist, PH.

1996-01-01

The FAUST (Focusing Adaptative UltraSonic Tomography) system was developed at the French Atomic Energy Commission (CEA) to improve performances of ultrasonic non destructive testing in terms of adaptability to various control configurations and defect characterization. Unlike conventional techniques only allowing fixed focusing, this system can dynamically modify the characteristics of the ultrasonic beam. This system relies on optimized phased array transducers connected to a multi-channel acquisition system supplying amplitude and delay laws allowing to drive the ultrasonic beam. Previous works have demonstrated the skills of this system for ultrasonic beam forming. The reliability of the procedure was proved by comparison with theoretical results, while comparisons with experimental results provided by conventional transducer pointed out the improved capacities of the system. In the first part of paper, we briefly present the model used for the system validation. This field computational model developed at the CEA is used to design optimized phased array transducers dedicated to NDE configurations (immersed transducers used to focus through Fluid/Solid interfaces). Theoretical delay laws and related ultrasonic fields are also calculated from this model. In addition to its ability to dynamically form the ultrasonic beam by taking account of the control configuration, we investigate in the second part of the paper the capabilities of the system to extract informations from he received signals. The ability of the system to store the signals received by all the elements of the array allows one to perform different reconstruction procedures. Useful informations can be extracted from the received signals: experimentally measured delay laws can be determined from reflected signals to obtain an optimal imaging, while the related amplitude distribution over the array points out geometrical characteristics of the reflector.

2017-11-01

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

Full Text Available Sparganosis caused by invasion of the plerocercoid larvae (spargana of Spirometra erinaceieuropaei have increased in recent years in China. However, the population genetic structure regarding this parasite is still unclear. In this study, we used the sequences of two mitochondrial genes cytochrome b (cytb and cytochrome c oxidase subunit I (cox1 to analyze genetic variation and phylogeographic structure of the S. erinaceieuropaei populations.A total of 88 S. erinaceieuropaei isolates were collected from naturally infected frogs in 14 geographical locations of China. The complete cytb and cox1 genes of each sample was amplified and sequenced. Total 61 haplotypes were found in these 88 concatenated sequences. Each sampled population and the total population have high haplotype diversity (Hd, accompanied by very low nucleotide diversity (Pi. Phylogenetic analyses of haplotypes revealed two distinct clades (HeN+HuN+GZ-AS clade and GX+HN+GZ-GY clade corresponding two sub-networks yielded by the median-joining network. Pairwise FST values supported great genetic differentiation between S. erinaceieuropaei populations. Both negative Fu's FS value of neutrality tests and unimodal curve of mismatch distribution analyses supported demographic population expansion in the HeN+HuN+GZ-AS clade. The BEAST analysis showed that the divergence time between the two clades took place in the early Pleistocene (1.16 Myr, and by Bayesian skyline plot (BSP an expansion occurred after about 0.3 Myr ago.S. erinaceieuropaei from central and southern China has significant phylogeographic structure, and climatic oscillations during glacial periods in the Quaternary may affect the demography and diversification of this species.

The present study was performed to investigate the infection status with helminth in a group of feral cats in Korea. More than 29 helminth species including adults or eggs were detected in visceral and fecal samples of the examined cats. Among these were a host of nematodes, including toxocarids, Ancylostoma sp. and the larva of Anisakis simplex; trematodes, including Clonorchis sinensis, Paragonimus westermani, Eurytrema pancreaticum, Pharyngostomum cordatum, Metagonimus spp., Heterophyes nocens, Pygidiopsis summa, Heterophyopsis continua, Stictodora fuscata, Stictodora lari, Acanthotrema felis, Stellantchasmus falcatus, Centrocestus armatus, Procerovum varium, Cryptocotyle sp., Echinostoma revolutum, Echinostoma hortense, Echinochasmus japonicus, Stephanoprora sp., Plagiorchis muris, Neodiplostomum sp. and diplostomulum. We also detected a variety of cestodes, including Spirometra erinacei, Taenia taeniaeformis and unidentified species of tapeworm. We also found examples of the acanthocephalan, Bolbosoma sp. In our assessment of the stools, we detected at least 12 species of helminth eggs. These findings confirmed that feral cats in Korea are infected with a variety of helminth parasite species. Furthermore, among the helminths detected, E. pancreaticum, S. fuscata, S. lari, A. felis, S. falcatus, C. armatus, P. varium, Cryptocotyle sp., E. revolutum, E. japonicus, Stephanoprora sp., P. muris, Neodiplostomum sp. and Bolbosoma sp. represent helminth fauna which have not been reported previously in feral cats in the Republic of Korea.

M Taghavi

2010-06-01

Full Text Available The following article is a comparative study of Attar’s Sheik of San’an and Goethe’s Faust. Both stories demonstrate a similarity of theme and structure as they call upon the reader to discover the external world through journey and have a deeper conception of his inner self via meditation and contemplation though it is true that Attar and Goethe have different worldviews and that they belong to two diametrically opposed epochs. They have a similar conception of certain things and have therefore used a certain structure to express them. Furthermore, both stories express religious themes in a new way that transcends the tradition. The author has also tried to show that the Islamic mysticism might have been a source of inspiration for Goethe.

The present study was aimed to examine the specific features of the helminth fauna in insular populations of the bank vole (Myodes glareolus) in the north of the species range. The material was collected in and nearby the Kizhi Archipelago (Lake Onega, 62°1' N 35°12' E) during August 1997, 2005-2007, 2012 and 2013. Small mammals were trapped on 23 islands (varying from 2 to 15,000 ha) and on the mainland. Helminthological met- hods were applied to examine 301 specimens of M glareolus. Fourteen helminth species were found: trematodes--Skrjabinoplagiorchis vigisi; cestodes--Paranoplocephala omphalodes, P. gracilis, Catenotaenia henttoneni, Taenia mustelae, Cladotaenia globife- ra, Spirometra erinacei; nematodes--Trichocephalus muris, Aonchotheca murissylvatici, Hepaticola hepatica, Heligmosomum mixtum, Heligmosomoides glareoli, Longistriata minuta, Syphacia petrusewiczi. The parasites S. vigisi, S. erinaci, H. hepatica and T. muris were identified in the bank vole in Karelia for the first time. Significant differences were detected between the helminth faunas of local insular populations of the bank vole. A distinctive feature of all small islands was that samples from them lacked the widespread pa- rasitic nematode Heligmosomum mixtum. The studies have confirmed the general trends observed in the parasite fauna of most isolated populations of small mammals: a poorer species diversity and high infestation rates with certain species of parasites. The Kizhi Archipelago is characterized by the specific high abundance of regionally rare parasite species (H hepatica, A. murissylvatici), and by the absence of common parasites (H. mixtum, H. glareoli).

Patient 1: After contact to a central European hedgehog (Erinaceus europaeus), a 50-year-old female with atopy developed erythrosquamous tinea manus on the thumb and thenar eminence of the right hand. The patient had previously been scalded by hot steam at the affected site. The zoophilic dermatophyte Trichophyton erinacei could be cultured from the hedgehog as well as from scrapings from the woman's skin. Antifungal treatment of the hedgehog was initiated using 2 weekly cycles of itraconazole solution (0.1 ml/kg body weight, BW). In addition, every other day enilconazole solution was used for topical treatment. The patient was treated with ciclopirox olamine cream and oral terbinafine 250 mg daily for 2 weeks, which led to healing of the Tinea manus .Patient 2: An 18-year-old woman presented for emergency consultation with rimmed, papulous, vesicular and erosive crusted skin lesions of the index finger, and an erythematous dry scaling round lesion on the thigh. The patient worked at an animal care facility, specifically caring for hedgehogs. One of the hedgehogs suffered from a substantial loss of spines. Fungal cultures from skin scrapings of both lesions yielded T. erinacei. Treatment with ciclopirox olamine cream and oral terbinafine 250 mg for 14 days was initiated which led to healing of the lesions. Identification of all three T. erinacei isolates from both patients and from the hedgehog was confirmed by sequencing of the internal transcribed spacer (ITS) region of the ribosomal DNA, and of the translation elongation factor (TEF)-1-alpha gene. Using ITS sequencing discrimination between T. erinacei strains from European and from African hedgehogs is possible. T. erinacei should be considered a so-called emerging pathogen. In Germany the zoophilic dermatophyte T. erinacei should be taken into account as causative agent of dermatomycoses in humans after contact to hedgehogs.

Full Text Available Spirometra is a genus of pseudophyllidean cestode that reproduces in canines and felines but can cause pathology in humans. When humans harbour plerocercoids of these tapeworms outside the intestine, it can cause sparganosis. We report a case of urinary sparganosis in a young woman, passing multiple spargana worms in her urine. The worm was identified as the plerocercoid larvae of Spirometra spp., and the case was managed successfully.

Human sparganosis, a neglected food borne zoonosis.

Science.gov (United States)

Liu, Quan; Li, Ming-Wei; Wang, Ze-Dong; Zhao, Guang-Hui; Zhu, Xing-Quan

2015-10-01

Human sparganosis is a food borne zoonosis caused by the plerocercoid larvae (spargana) of various diphyllobothroid tapeworms of the genus Spirometra. Human infections are acquired by ingesting the raw or undercooked meat of snakes or frogs, drinking untreated water, or using raw flesh in traditional poultices. More than 1600 cases of sparganosis have been documented worldwide, mostly in east and southeast Asia. Sporadic cases have been reported in South America, Europe, and Africa, and several cases have been described in travellers returning from endemic regions. Epidemiological data suggest that the increased effect of sparganosis on human health is because of greater consumption of raw meat of freshwater frogs and snakes. This Review provides information about the Spirometra parasites and their lifecycles, summarises clinical features, diagnosis, and treatment of human sparganosis, and describes geographical distribution and infection characteristics of Spirometra parasites in host animals.

Full Text Available Abstract Cats are carriers of zoonotic agents to humans, including intestinal parasites. The purpose of this study was to analyze the accuracy of different laboratory methods for the diagnosis of intestinal parasites. Fecal samples were processed by the Willis, Sheather, Faust and Hoffman-Janer-Pons-Lutz (HJPL methods. Accuracy analysis was performed determining the sensitivity, specificity, positive and negative predictive value and Kappa. A total of 149 fecal samples were collected, 65 from stray cats and 84 from domiciled cats. The prevalence of intestinal parasites in stray cats was 60% while in domiciled cats it was 17%. In the analysis of accuracy, the techniques that showed the greatest accuracy for Ancylostomids were Willis and Faust, for Cystoisospora spp. Sheather with Faust or HPJL, and Toxoplasma gondii/Hammondia hammondi the association between Willis and Faust. Therefore, for a reliable evaluation of the prevalence of intestinal parasites, at least two different techniques should be used in parasitological exams of feces.

Full Text Available The occurrence of dermatophytes and keratinophilic fungi was investigated by hair-brush technique on the coat of 986 apparently healthy brown hares (Lepus europaeus, Pallas 1778 caught in 9 restocking and capture zones in Central Italy. Overall, 7.5% hair samples gave positive results. Trichophyton terrestre (2.1%, Chrysosporium sp, Chrysosporium keratinophilum, Microsporum gypseum, Trichophyton gloriae and Trichophyton mentagrophytes (0.6% each, Trichophyton erinacei and Scopulariopsis brevicaulis (0.4% each, Chrysosporium asperatum (0.3%, Arthroderma sp and Microsporum canis (0.1% each were identified in cultures with single isolates, whereas Chrysosporium sp/T. mentagrophytes (0.3%, Chrysosporium sp/T. terrestre and M. gypseum/T. terrestre (0.2% each, Chrysosporium tropicum/T. terrestre, M. canis/T. terrestre and T. ajelloi/T. terrestre (0.1% each were identified in cultures with mixed isolates. T. erinacei and M. canis have not previously been isolated from hares. M. canis, T. erinacei and T. mentagrophytes were the most clinically important dermatophytes found. Altogether, they were isolated only from 1.5% hair samples. Thus, it is concluded that brown hares may play a limited epidemiological role as carriers of zoonotic dermatophytes. Nevertheless, this should be taken into consideration as many people may be exposed to zoonotic agents from brown hares during hunting and trapping activities.

Gastrointestinal zoonotic helminths of dogs and cats have a public health concern worldwide. We investigated the prevalence of gastrointestinal helminths of zoonotic significance in dogs and cats in lower Northern Thailand and utilized molecular tools for species identification of hookworms and Opisthorchis viverrini. Fecal samples of 197 dogs and 180 cats were collected. Overall prevalence of infection using microscopy was 40.1% in dogs and 33.9% in cats. Helminth infection found in both dogs and cats included hookworms, Spirometra spp., Taenia spp., Toxocara spp., O. viverrini, Strongyloides spp. and Trichuris spp. Hookworms were the most common helminth in dogs, while Spirometra spp. were the most prevalent in cats. Among hookworm infection in dogs and cats, Ancylostoma ceylanicum was the most prevalent hookworm, being 82.1% in hookworm infected dogs and 95.8% in hookworm infected cats. Mixed-infection due to hookworms and Spirometra spp. was the most dominant in both dogs and cats. Our finding showed that zoonotic helminth infection is highly prevalent in dogs and cats in the lower Northern area of Thailand.

Full Text Available Background: Ixodid ticks (Acari: İxodidae and fleas (Siphonaptera are the major vectors of pathogens threatening animals and human healths. The aim of our study was to detect the infestation rates of East Hedgehogs (Erinaceus concolor with ticks and fleas in Van Province, eastern region of Turkey.Methods: We examined fleas and ticks infestation patterns in 21 hedgehogs, collected from three suburbs with the greater of number gardens. In order to estimate flea and tick infestation of hedgehogs, we immobilized the ectoparasites by treatment the body with a insecticide trichlorphon (Neguvon®-Bayer.Results: On the hedgehogs, 60 ixodid ticks and 125 fleas were detected. All of the ixodid ticks were Rhipicephalus turanicus and all of the fleas were Archaeopsylla erinacei. Infestation rate for ticks and fleas was detected 66.66 % and 100 %, respectively.Conclusion: We detected ticks (R. turanicus and fleas (A. erinacei in hedgehogs at fairly high rates. Since many ticks and fleas species may harbor on hedgehogs and transmit some tick-borne and flea-borne patogens, this results are the important in terms of veterinary and public health.

Full Text Available Helminths from a total of 24 species of small mammals, representing three orders (Insectivora, Chiroptera, Rodentia were examined in Zhiguli State Reserve (Russia. 90 species of helminthes were identified: Trematoda – 24, Cestoidea – 21, Nematoda – 43 and Acanthocephala – 2. For each helminth species the following traits are specified: systematic position, hosts, localization, host specificity, sites of findings and geographical distribution. Rodents, in which 33 helminth species were noted, were proven to have the richest parasite fauna. In chiropterans and insectivores 32 and 28 species of helminths were registered, respectively. Only one parasite species was common for all three orders of mammals – the acanthocephalan Moniliformis moniliformis. 14 species of parasites were discovered in mammals of Russia for the first time: Prosthodendrium hurkovaae, Rodentolepis erinacei, Staphylocystis syrdariensis, Aonchotheca erinacei, Crenosoma striatum, Tricholinstowia linstowi, T. talpae, Molinistrongylus alatus, M. spasskii, M. vespertilionis, Pterothominx neopulchra, Pterygodermatites bovieri, Syphacia nigeriana, Centrorhynchus aluconis, larvae, Moniliformis moniliformis, larvae. 21 species of parasitic worms were found for the first time in mammals of the Volga River basin. Nine helminth species, discovered in small mammals of the Zhiguli State Reserve, are of epidemiological and epizootiological importance.

Nuclear waste: beyond Faust and fate

International Nuclear Information System (INIS)

Maxey, M.N.

1979-01-01

Regarding development of the nuclear industry and the resulting turmoil over generation of nuclear wastes, Dr. Maxey presents as a fundamental bioethical principle for organizing evidence and dealing with conflicting opinions the following formulation: social justice requires an equitable mangement of potential hazards that might have harmful health effects and unjustifiable social consequences. By equitable management she means: (1) comprehensively informing policymakers about the broad spectrum of hazards; (2) make comparisons of actual costs to reduce the effects; and (3) only then make policies and set standards that will get the most public protection out of a finite amount of money. Translating this principle into public policy is no easy task, since opponents have developed several arguments that appeal to nonscientific moral and ethical premises. Briefly, these statements can be summarized as: (a) indefinite delay of high-level waste disposal facilities is regarded as morally preferable to a policy of implementing one of several currently available options, and (b) it is claimed that involuntary risks of radiation exposure imposed on present and unconsulted future generations violate ethical principles of social justice and equity. Dr. Maxey uses most of the article in countering these premises and finally suggests the following bioethical principle for guidance: any involuntary risks imposed by social policies for radiation protection must be congruent with, must not be in excess of, and may be reasonably less than, those involuntary risks imposed by the naturally occurring toxic elements and harmful effects from our natural environment

Full Text Available The effectiveness of a waste stabilization pond, to remove intestinal helminth eggs and protozoan cysts was studied in San Martin de Porres, Lima, Peru. From September to October 2000 four collections of samples were performed from raw domestic wastewater and from contends of primary, secondary and tertiary ponds. A comparative study of performance of the concentrations methods of Ritchie and Faust was also done. The overall average removal of parasitic forms was as follow: 69.37% from raw water and primary pond; 48.34% from primary to secondary pond; 85.45% from secondary to tertiary pond and 97.69% from raw water to tertiary pond. There was no significant difference in the quantitative performance of Ritchic and Faust methods. Giardia duodenalis (Lambl, 1859 Alexeieff, 1914, Entamoeba coli (Gras, 1879 Casagrandi & Barbagallo, 1895 and Ascaris lumbricoides (Linnaeus, 1758 were detected with both methods. Three other parasites were detected only by Ritchie method: Taenia sp., Rodentolepis nana (von Siebold, 1852 Spasskii, 1954 and Trichuris trichiura (Linnaeus, 1771 Stiles, 1901 and only Faust detected Isospora belli Wenyon, 1923. Overall number of protozoa cysts was higher than the number of helminth eggs. At the end, wastewater had a concentration of 1.5 parasitic forms L¹ what is considered inappropríate for ultimate use in agriculture by current standards.

As early as 1846, the typical symptoms of attention deficit hyperactivity disorder (ADHD) were described by Heinrich Hoffmann (1809-1894). However, in Goethe's masterpiece Faust (1832), the character of Euphorion strongly suggests ADHD diagnosis. Copyright © 2011 S. Karger AG, Basel.

Repensando os desafios de Ulisses a Fausto: a saúde, o indivíduo e a história Rethinking the challenges of Ulysses and Faust: health, the individual and history

Directory of Open Access Journals (Sweden)

Djalma A. de Melo-Filho

1995-03-01

Full Text Available Em torno de duas sinédoques históricas, Ulisses e Fausto, o texto retoma a etimologia do termo saúde (do latim salute, tratando-a como uma unidade entre as "necessidades existenciais" e as "necessidades propriamente humanas", que desemboca no desafio de satisfazer o "conservar a vida" e, ao mesmo tempo, o "passar por cima de, saltando". Ambos os significados encontram-se, respectivamente, presentes na atitude de Ulisses em não sucumbir ante o canto das sereias e no desejo de Fausto em elevar-se da vida cotidiana. Criticam-se alguns aspectos da concepção marxista da filosofia da história e do marxismo-estruturalista de Althusser. Analisa-se, ainda, à luz da teoria marxista-helleriana, a hipótese de que o alvo do Relatório Final da 8ª Conferência Nacional de Saúde teria sido o homem-particular e não o indivíduo, pois a saúde ali é tratada apenas como uma "necessidade existencial", não objetivando o humano-genérico. Como desafio teórico, o texto, visando ao devir do indivíduo, recomenda, finalmente, a construção de "suturas epistemológicas" entre natureza/sociedade, entre vida cotidiana/universalidade e entre o jovem e o velho Marx.Concentrating on two historical synecdoches, Ulysses and Faust, this article takes up the etymology of the Latin term salute as a unit lying somewhere between "existential needs" and "especially human needs", leading to the challenge of satisfying the need for "conservation of life" and at the same time to "surpass it, go beyond it". Both meanings are present in Ulysses’ attitude of not succumbing to the siren’s melody and in Faust’s desire to rise above everyday life. Some aspects of the Marxist conception of the philosophy of history and Althusser’s Structuralist Marxism are criticized. Also, in light of Marxist-Hellerian theory, the article analyzes the hypothesis that the target of the final reports of the VIII National Health Conference was "particular man" and not the individual

Full Text Available Heavy-ion collisions at lower energies provide a rich environment for investigating reaction dynamics. Recent theory has suggested a sensitivity to the symmetry energy and the equation of state via deformations of the reaction system and ternary breaking of the deformed reaction partners into three heavy fragments. A new detection system has been commissioned at Texas A&M University in an attempt to investigate some of the observables sensitive to the nuclear equation of state.

Nuclear genie: beyond Faust, fate, and incantations

International Nuclear Information System (INIS)

Maxey, M.N.

1980-01-01

Dr. Maxey fears that public reaction to the anti-nuclear movement may have eliminated nuclear energy as a future option for the US. She notes that recurrent themes of the movement go beyond a genuine concern for remaining technical problems. Focusing on the personal and social threats associated with extravagant energy consumption, the campaign is waged by competing groups struggling for political power. They use non-technical issues to create divisiveness and drive a wedge between scientists and humanists. It is important to realize that activists and the media seek social change by portraying nuclear technology as a Faustian bargain and ignoring the benefits it offers. An ethical framework is needed in which counter arguments in support of nuclear energy can be examined and compared with the soft technologies and the concept of a risk-free world. Dr. Maxey feels that the bioethical approach, which recognizes that human action can inflict basic harm, is improperly applied to nuclear energy alone and needs to be reevaluated; further, the US should lead in defining the benefits and harms inherent in all human actions and develop a philosophy of congruence which puts nuclear energy in its historical context. Because it is naive to think that the world can have a non-nuclear future, she says the US should provide leadership in international controls. 21 references

Don Juan: eine Tragödie. Intertestualità faustiana e riscrittura tragica nel racconto di E. T. A. Hoffmann

Directory of Open Access Journals (Sweden)

Francesco Marola

2017-11-01

Full Text Available Il mito letterario di don Giovanni, sorto nella commedia, attorno al 1800 viene riformulato in direzione del tragico. La trasformazione inizia con la versione operistica di Mozart-Da Ponte e trova compimento nel racconto di Hoffmann, che proietta il nuovo tono tragico del finale mozartiano su tutto il mito. L’articolo intende porre in rilievo la presenza nel Don Juan di numerosi richiami intertestuali al Faust di Goethe, finora non pienamente rilevati dalla critica, attraverso i quali è possibile leggere tale riscrittura tragica come una dichiarata sintesi dei due miti, in cui don Giovanni assume il ruolo di Faust-Mefistofele e donna Anna quello di Gretchen. La riscrittura del mito culmina nel finale rispecchiamento del narratore in Anna-Gretchen. Ma il valore del tragico è relativizzato in Hoffmann dall’ironica autocoscienza dell’artista romantico: confinato nel mondo fantastico dell’arte, risulta privo di senso nella prosaica realtà della vita borghese.

Hedgehogs (Erinaceus europaeus as a Source of Ectoparasites in Urban-suburban Areas of Northwest of Iran

2015-10-01

Full Text Available Background: Hedgehogs are small, nocturnal mammals which become popular in the world and have important role in transmission of zoonotic agents. Thus, the present study aimed to survey ectoparasite infestation from April 2010 to December 2011 in urban and suburban parts of Urmia and Tabriz Cities, Northwest of Iran.Methods: A total number of 84 hedgehogs (40 females and 44 males were examined. They have been carefully inspected for ectoparasites and collected arthropods were stored in 70% ethanol solution. The identification of arthropods was carried out using morphological diagnostic keys.Results: The occurrence of ticks on hedgehogs was 23 (67.7% with Rhipicephalus turanicus in Urmia and 11 (22% as well as 1(2% with Rh. turanicus and Hyalomma anatolicum anatolicum in Tabriz, respectively. One flea species, Archaeopsylla erinacei, was found with prevalence of 19 (55.9% and 27 (54% in Urmia and Tabriz Cities, respectively. Prevalence of infestation with Rh. turanicus and A. erinacei were not different (P> 0.05 between sexes of hedgehogs in two study areas. Highest prevalence of tick and flea infestation was in June in Urmia, whereas it was observed in August in Tabriz. Both tick and flea parasitizing hedgehogs showed seasonal difference in prevalence (P< 0.05 in Urmia, but it was not detected in Tabriz (P> 0.05.Conclusion: The result showed the high occurrence of ectoparasites in hedgehog population and according to the zoonotic potential of these animals as vector of some agents further studies are needed to investigate in different parts of Iran.

Full Text Available A survey was undertaken to investigate the prevalence of gastrointestinal parasites in different groups of mammals housed at Rangpur Recreational Garden and Zoo in Bangladesh. A total of 45 fecal samples of different animals (11 carnivores, 26 herbivores and 8 primates were examined from April to September 2011 for the presence of gastrointestinal parasites. The overall prevalence of parasitic infection was 60% (27/45 of which 35.6% (16/45 were helminth infections and 24% (11/45 were protozoic infections. The identified parasites included protozoa (Balantidium coli and Coccidia sp., nematodes (Toxascaris leonina, Toxocara cati, Strongyloides sp., Dictyocaulus sp., Trichuris sp. and stomach worm, cestodes (Spirometra sp. and Moniezia benedeni and trematodes (Fasciola sp.. At least one parasite was identified in the fecal samples of all animals except of the samples from bear, python, water buck and olive baboon. Mixed infections were observed in Rhesus monkey (Trichuris sp. and Balantidium coli, in deer (Strongyloides sp. and Coccidia sp. and in lion (Toxascaris leonina and Spirometra sp.. Helminth infections were more common than protozoic infections in carnivores and herbivores, whereas in primates, protozoic infections were more common than helminth infections. The high prevalence of gastrointestinal parasites found in zoo animals in this study emphasizes the importance of controlling these parasitic infections in order to safeguard the health of housed wild animals and of the humans working with these animals.

Giardia infection is a common clinical problem in humans and pets. The diagnosis of giardiasis is challenging as hosts intermittently excrete protozoan cysts in their feces. In the present study, we comparatively evaluated two methods of serial fecal sampling in humans, dogs, and cats from Rio de Janeiro, Brazil. The Faust et al. technique was used to examine fecal specimens collected in triplicate from 133 patients (52 humans, 60 dogs, and 21 cats). Specimens from 74 patients were received from the group assigned to carry out sampling on consecutive days - 34 humans, 35 dogs, and 5 cats, and specimens from 59 patients were received from the group assigned to carry out sampling on non-consecutive, separate days - 18 human beings, 25 dogs, and 16 cats. G. duodenalis cysts were found in stools of 30 individuals. Multiple stool sampling resulted in an increase in the number of samples that were positive for Giardia in both groups. The authors therefore conclude that multiple stool sampling increases the sensitivity of the Faust et al . technique to detect G. duodenalis cysts in samples from humans, cats and dogs.

Full Text Available 1. Scopo L’obiettivo di questo lavoro è quello di indagare le modalità e la fenomenologia della penetrazione di un mito profondamente occidentale — come quello di Faust — nella produzione di uno tra i più noti scrittori e drammaturghi arabi del Novecento: Tawfiq al-Hakim, concentrandosi in particolare su una sua novella del 1938, Ahd al-Shaytān (Il patto col diavolo. 2. Metodologia La novella, scelta in quanto exemplum rappresentativo di una pratica corrente nella produzione dell’autore, ovvero la rifunzionalizzazione di argomenti e personaggi mitologici di varia derivazione, viene analizzata nella prospettiva di una rivisitazione della leggenda di Faust e del suo patrimonio tematico e iconografico. La sua analisi permette di rilevare le tappe di un percorso assai interessante: quello della penetrazione e integrazione di un mito dell’Occidente moderno nella tradizione araba, considerato alla luce degli effetti che l’interazione con gli elementi tradizionali e autoctoni di quel patrimonio producono sul processo di assimilazione. 3. Risultati In quest’ottica, il corpus di Tawfiq al-Hakim appare fondante, non solo in virtù della sua familiarità con la trattazione di temi mitici provenienti anche dalla tradizione occidentale, ma per gli elementi di novità ed esclusività che da quella trattazione emergono.

Full Text Available This article intends to follow the development of the Faustian myth through a number of outstanding films in western culture ending with Faust 5.0 by Fura dels Baus. It starts with a brief analysis of the Faust inscribed in literature by Spiess in 1587 and, progressively, implemented by several European authors up to the Manns. The number of literary and filmic Fausts is so large that this article, a work in progress, provides only a few steppingstones, those considered more relevant in the history of the myth. The main characteristics of the legend are kept as the leading structure of this article, considering the fact that those are the moments that attract the attention of writers and directors and, therefore, suffer more modifications. Modifications that follow the philosophical thought and the social changes of the time in which they were written or filmed. Accordingly, contemporary Fausts bear the imprint of the new technologies and the feminist, postmodern, postcolonial or transcultural perspectives of our era.

La leyenda fáustica, en la que el personaje principal vende su alma al diablo por conseguir lo que más anhela en ese momento, se ha convertido, desde su primera publicación en la imprenta de Johann Spiess en 1587, en un tema recurrente en diferentes medios artísticos. En la literatura en todas sus manifestaciones, en pintura, música y cine, diferentes Faustos soñaron con el placer, el conocimiento, la fama, el dinero o el poder, y aprendieron, de manera dramática, que la vida es breve y los logros humanos efímeros. Puesto que la duda primordial de qué hay después de la muerte no puede ser satisfecha, la venta del alma se convierte en una transacción fútil o trágica, según fuera la respuesta, que ningún Fausto llega a dilucidar. Mefistófeles, el mensajero del diablo, no tiene más remedio que convertirse en un mago o en un bufón para distraer a su señor terrenal, para que no piense en temas trascendentales

Spanning space and time boundary, we discover that both Jia Baoyu and the Faust have the similarity disposition that pursue the highest life value and have the contradiction and the pain which is unable to get rid, finally obtained the spiritual extrication. Their tragedy experience and the tragedy destiny express the earnest hope to realize the humanity freedom and the surmounting, and has displayed infinite yearning for the human nature and the personality harmonious. Facing the realistic and ideal contradictory conflict, Faust's individuality shows more positive initiative and the creativity.

Late detection, early metastases, difficult surgical approached, cancer resistant to systemic chemo and radiotherapy - all contribute to its in faust prognosis. Only about 5 % of patients will live 5 years after diagnosis. Gemcitabine - based combination treatments is the standard for advanced pancreatic cancer. The combination of fluorouracil, folinic acid, irinotecan and oxaliplatin led to median survival of 11 months. No standard second-line treatment exists for pancreatic cancer. (author)

Full Text Available The purpose of this paper is to compare two prologs, namely ‘Prolog im Himmel’ in Faust I and the prolog in Der gute Mensch von Sezuan by Brecht. The comparative analysis of the two texts provides evidence to state that Brecht produces a parody of Goethe´s prolog. This procedure is interpreted here as a feature of 20th century literature. Intertextuality and recreation are seen as a way to characterize a shapeless present and are approached by drawing an analogy and critically comparing and contrasting Brecht’s prolog to a literary masterpiece.

Calibration of a Fusion Experiment to Investigate the Nuclear Caloric Curve

Keeler, Ashleigh

2017-09-01

In order to investigate the nuclear equation of state (EoS), the relation between two thermodynamic quantities can be examined. The correlation between the temperature and excitation energy of a nucleus, also known as the caloric curve, has been previously observed in peripheral heavy-ion collisions to exhibit a dependence on the neutron-proton asymmetry. To further investigate this result, fusion reactions (78Kr + 12C and 86Kr + 12C) were measured; the beam energy was varied in the range 15-35 MeV/u in order to vary the excitation energy. The light charged particles (LCPs) evaporated from the compound nucleus were measured in the Si-CsI(TI)/PD detector array FAUST (Forward Array Using Silicon Technology). The LCPs carry information about the temperature. The calibration of FAUST will be described in this presentation. The silicon detectors have resistive surfaces in perpendicular directions to allow position measurement of the LCP's to better than 200 um. The resistive nature requires a position-dependent correction to the energy calibration to take full advantage of the energy resolution. The momentum is calculated from the energy of these particles, and their position on the detectors. A parameterized formula based on the Bethe-Bloch equation was used to straighten the particle identification (PID) lines measured with the dE-E technique. The energy calibration of the CsI detectors is based on the silicon detector energy calibration and the PID. A precision slotted mask enables the relative positions of the detectors to be determined.

Invaded Invaders: Infection of Invasive Brown Treesnakes on Guam by an Exotic Larval Cestode with a Life Cycle Comprised of Non-Native Hosts.

Full Text Available Multiple host introductions to the same non-native environment have the potential to complete life cycles of parasites incidentally transported with them. Our goal was to identify a recently detected parasitic flatworm in the invasive Brown Treesnake (Boiga irregularis on the remote Pacific island of Guam. We considered possible factors influencing parasite transmission, and tested for correlations between infection status and potential indicators of host fitness. We used genetic data from the parasite and information about the native ranges of other possible non-native hosts to hypothesize how it arrived on Guam and how its life cycle may be currently supported.We identified the parasite by comparing larval morphology and mtDNA sequences with other Pseudophyllid tapeworms. We assessed probability of infection in individual snakes using logistic regression and examined different factors influencing presence of parasites in hosts.We identified the parasite as the pseudophyllid cestode Spirometra erinaceieuropaei, with all sampled worms from multiple snakes sharing a single mtDNA haplotype. Infection appears to be limited to the only freshwater watershed on the island, where infection prevalence was high (77.5%. Larger snakes had a higher probability of being infected, consistent with the chronic nature of such infections. While infection status was positively correlated with body condition, infected snakes tended to have lower intra-peritoneal fat body mass, potentially indicating a negative effect on energy stores.We discovered that B. irregularis inhabiting a small area of forested habitat in a freshwater watershed on Guam are often infected by a novel parasite of Asian origin. While further work is needed, this species of Spirometra, itself a non-native species, likely depends on a suite of recently introduced hosts from different parts of the world to complete the life cycle. This baseline study provides little evidence of any effects on host

Full Text Available Abstract Our work bases on the hypothesis of an existing interconnection between the symbolic and the metaphoric elements of the text responding to a series of mind patterns compressing perception and experience through the emerging process of conceptual blending triggering the semantic process during the creative act of poiesis. This enquiry focuses on the use of a peculiar rhetorical figure in an exemplar literary text of the famous German poet Goethe. We will try to point out the allegorical function of the scene dedicated to the «Mothers’ Kingdom», in his Faust II as a powerful poetical meta-reflection on imagination, cognition and poetics itself.

A técnica de centrífugo-flutuação com sulfato de zinco (FAUST et al., 1938 é técnica de eleição no diagnóstico de estruturas parasitárias leves, podendo também ser usada para detecção de estruturas pesadas. Para avaliar o desempenho dessa técnica no diagnóstico das helmintoses gastrintestinais de gatos domésticos, foram realizados exames coproparasitológicos de 13 gatos domésticos 15 dias antes de suas mortes. À necropsia, os helmintos adultos encontrados no tubo digestivo e fígado foram contados, fixados e identificados. A técnica utilizada mostrou-se capaz de recuperar ovos de todos os nematóides e trematódeos encontrados, mas não foi adequada para a recuperação de cestóides.Fecal examinations are the most commonly used laboratory tool for diagnosis of gastrointestinal nematode parasitic infections. Zinc centrifugal floatation technique (FAUST et al., 1938 is not only considered to be efficient in detecting light parasitic structures, but it is also used for recovery of heavy structures. In order to evaluate the performance of that technique in the diagnosis of domestic cats' gastrointestinal helminthiasis, fecal examinations of 13 animals were carried out 15 days prior to the animals' deaths. At necropsy, adult gastrointestinal parasites found were collected, counted, fixed and identified. The studied technique was able to recover eggs from all detected nematodes and trematodes, but appeared inappropriate for recovery of cestode eggs.

Os fatores sócio-econômicos, como distribuição de renda, escolaridade e categorias ocupacionais, foram importantes dentro deste contexto. O hábito de ingerir hortaliças e frutas foram os fatores mais associados ao alto grau de parasitismo. Conclui-se que, nesta cidade, os manipuladores de alimentos apresentaram elevados índices de parasitose, havendo necessidade de uma melhor vigilância epidemiológica por meio de exames parasitológicos e educação sanitária a todos esses indivíduos.The presence of intestinal parasites and epidemiological aspects were evaluated in 238 workers from a fast food company and other individuals working in street markets and farmers' produce markets in the city of Florianópolis, Santa Catarina State, Brazil. Parasitological techniques used in this study were: Lutz, Baermann-Moraes, Graham, and Faust, and parasite infection rates were 42.85% and 47.06%, respectively. Socioeconomic factors such as income distribution, schooling, and occupational categories proved to be relevant in this context. Habitual daily intake of fruits and vegetables was the factor most heavily associated with infection. These data suggest that intestinal parasites are frequent among food handlers in this city and that there is a need for constant epidemiological surveillance through periodic parasitological tests and health education for this entire population segment.

PORTRAIT IN LITERATURE AND GRAPHIC ART: THE CASE OF THE FIERY ANGEL

Full Text Available This essay analyzes portraits in several editions of The Fiery Angel published during This essay analyzes portraits in several editions of The Fiery Angel published during Bryusov’s lifetime and claims that the portrait was as a universal point of convergence for verbal and visual arts. The dialogue between literature and graphics in the context of the synthesis of arts sheds new light on the possibilities for interdisciplinary research. The time of the “beautiful book” was a time of great artists and illustrators who introduced the peculiarities of their own style and the manner of their artistic schools into their art. Books were commonly decorated with vignettes and famous paintings. Portraits, as well as plates in general, were of the highest quality. They were ornamental and illusory, with every minute detail finely drawn out. Yet, in the second edition of the novel Bryusov deliberately included medieval engravings and portraits. A comparative analysis of the verbal portraits in The Fiery Angel and engraved portraits in the book (Ruprecht, Heinrich, Faust, Mephistopheles, Renata, and Madiel demonstrates that both the main and the secondary characters of the novel are picturesque and multidimensional whereas the xylographic portraits rather reveal conventionality and simplicity of the medieval time. This way Bryusov was seeking to debase clichе’s, especially as regards Agrippa von Nettesheim and Faust: according to Bryusov, the character of Agrippa had already become a clichе’d image and so was the popular engraving of the scientist that he reproduced in the middle of the sixth chapter of the 1909 edition. Juxtaposing the verbal and the graphic portraits in The Fiery Angel helps us better understand the function of the verbal portrait in a Symbolist text that was determined by the author’s design, on the one hand, and by various “instruments” of different arts, on the other.

Two photographs of the galaxy M 31 have been obtained in the far UV with a Faust rocket experiment and in the near UV with the S 183 experiment aboard Skylab. Only the central part of the galaxy is detected. Reductions provide both the energy received and the angular area over M 31 from which it is emitted. The UV flux is brighter than expected from extrapolation of the visible spectrum. The distribution below 300 A is rather flat and different from previous OAO-2 observations. These results, combined with Lyman continuum flux evaluation, are used to discuss the temperature and the age of the stars which may be responsible for this anomalous UV distribution.

The consumption of a wide variety of species of reptiles caught from the wild has been an important source of protein for humans world-wide for millennia. Terrapins, snakes, lizards, crocodiles and iguanas are now farmed and the consumption and trade of their meat and other edible products have recently increased in some areas of the world. Biological risks associated with the consumption of products from both farmed and wild reptile meat and eggs include infections caused by bacteria (Salmonella spp., Vibrio spp.), parasites (Spirometra, Trichinella, Gnathostoma, pentastomids), as well as intoxications by biotoxins. For crocodiles, Salmonella spp. constitute a significant public health risk due to the high intestinal carrier rate which is reflected in an equally high contamination rate in their fresh and frozen meat. There is a lack of information about the presence of Salmonella spp. in meat from other edible reptilians, though captive reptiles used as pets (lizards or turtles) are frequently carriers of these bacteria in Europe. Parasitic protozoa in reptiles represent a negligible risk for public health compared to parasitic metazoans, of which trichinellosis, pentastomiasis, gnathostomiasis and sparganosis can be acquired through consumption of contaminated crocodile, monitor lizard, turtle and snake meat, respectively. Other reptiles, although found to harbour the above parasites, have not been implicated with their transmission to humans. Freezing treatment inactivates Spirometra and Trichinella in crocodile meat, while the effectiveness of freezing of other reptilian meat is unknown. Biotoxins that accumulate in the flesh of sea turtles may cause chelonitoxism, a type of food poisoning with a high mortality rate in humans. Infections by fungi, including yeasts, and viruses widely occur in reptiles but have not been linked to a human health risk through the contamination of their meat. Currently there are no indications that natural transmissible spongiform

Full Text Available This paper presents an interpretation of the theme of transcendence in With my dog eyes, by Hilda Hilst, considering it as an example of the poetic disposition of her work. Such reading is based on Giorgio Agamben’s understanding of transcendence as an experimentum linguae, i.e., a poetic experience with language. We assume here that the character Amós Kéres, poet and mathematician, symbolizes the figure of the romantic writer in search of the originality of his writing. By narrating Amós’ experience of a profound existential tedium – in dialogue with Goethe’s Faust – Hilda Hilst presents the creative process (poiesis as an experience formally identical to a philosopher’s experience when confronting nothingness.

Full Text Available The so called "Nerv-Sprech" is a newly coined term classifying a specific group of colloquial phrasemes considered annoying by many German speakers. Apart from this affective evaluation of these phrasemes, their main common characteristic is the fact that they are the result of different processes of modification and/or incorporate paradoxical meaning.The online edition of the German magazine Der Spiegel has published a web dictionary of "Nerv-Sprech"-units, which functions as a ready-made corpus. This article categorizes these phraseological units as slogans, pragmatic or predicative phrasemes. Furthermore, in order to evaluate the validity of the term "Nerv-Sprech" from the point of view of the language system, I examine whether there are semantic or structural modifying aspects that are dominant among the phrasemes (and if so, which ones. Finally, a ludic function of "Nerv-Sprech" is postulated as a result of the creativity in modifying these phrasemes.

Dermatophytosis caused by Trichophyton erinacei is a common scaling and crusting skin disease affecting European hedgehogs (Erinaceus europaeus) admitted to wildlife rescue centres. The application of topical therapy can be challenging because wild hedgehogs are subject to stress and often roll into a ball when handled. Systemic antifungal therapy is more convenient but has not been evaluated in this species. To compare the efficacy of oral itraconazole versus oral terbinafine for the treatment of dermatophytosis affecting hedgehogs. A treatment trial was undertaken in a wildlife hospital involving 165 hedgehogs with naturally occurring dermatophytosis. Animals were randomly divided into two groups and treated with either itraconazole or terbinafine orally for 28 days. The therapeutic efficacy was evaluated after 14 and 28 days by mycological culture and clinical dermatological lesion scores. Both drugs were well tolerated and clinically effective. After 14 and 28 days of treatment, the respective mycological cure rate was 36.6% and 65.9% for the itraconazole-treated group and 92.8% and 98.8% for the terbinafine-treated group. Itraconazole and terbinafine were both effective for the treatment of dermatophytosis affecting hedgehogs; however, terbinafine was more effective. © 2016 ESVD and ACVD.

Full Text Available Contemporary anxieties around cloning and genetic modification have deep roots in a nineteenth- and twentieth-century tradition of narrative thought-experiments about the artificial reproduction of human life. In the ‘strange wickedness’ to which HG Wells’s narrator refers—as good a condensation of the tradition’s topic as any—strangeness has always been as prominent as wickedness. In that tradition the myths of Prometheus and Faust, of the golem and the doppelgänger, together with fables and fictions concerning automata and scientifically produced monsters and/or reflections on the real and the illusory, have con- verged to define a problematics of the sorcerer’s apprentice. We will see that such a problematics reflects a powerful fear of artifice, or more accurately a phobia: a fear of artifice as great as the attraction it also exerts.

Full Text Available The occurrence of the enteroparasites was verified in 279 children (0 to 6 years of four municipal day cares of Botucatu/SP. Three samples of each child's feces were collected and processed by the methods of Hoffman-Pons-Janner, Faust and Ritchie and subsequent coloration of the fecal smear by the methods of Auramina-O and Ziehl-Neelsen modified for diagnosis of Cryptosporidium sp. and Graham method for diagnosis of Enterobius vermicularis. Of the analyzed children we verified a prevalence of intestinal parasitism in 53.40%, and the most frequent parasite was Giardia duodenalis (26.88%. Significant association was verified among enteroparasitosis, family income, maternal education and age; the lowest enteroparasite frequency occurred in children of families with larger income and higher education. It was observed that G. duodenalis is more prevalent in children from 0 to 4 years and E. vermicularis is more frequent in children between three and four years old. The high enteroparasite prevalence in day cares suggests complex structure in its epidemiology, where factors beyond sanitation should be considered.Verificou-se a prevalência dos enteroparasitas em 279 crianças (0 a 6 anos de quatro creches municipais de Botucatu/SP.

"His works forsake him as the birds forsake the nest in which they were hatched": on art, renouncement and death in Goethe’s Elective Affinities

Directory of Open Access Journals (Sweden)

Markus Lasch

2012-07-01

Full Text Available At the beginning of the second part of Goethe’s Elective Affinities the narrator draws a parallel between life and the stroke of art in the poet in order to replace, in an epic poem, the protagonists for figures hitherto scarcely observed, thereby justifying the increasing importance of the architect in the sequence of the novel. This young artist links to his art a hope for permanence, for survival. Ottilie disagrees in the notes of her diary. She sees in the ruins of the churches and the wreckage of the gravestones not only proof of the transitoriness of this life, but also of the extinction of a second existence post mortem: "Time will not allow itself to be cheated of its rights over men or over monuments". Based on Walter Benjamin’s essay on the Elective Affinities and considering another magnum opus by Goethe, Faust, this article discusses the aspects of art, renouncement and death in the poet’s work.

Quantum Humor: The Playful Side of Physics at Bohr's Institute for Theoretical Physics

Science.gov (United States)

Halpern, Paul

2012-09-01

From the 1930s to the 1950s, a period of pivotal developments in quantum, nuclear, and particle physics, physicists at Niels Bohr's Institute for Theoretical Physics in Copenhagen took time off from their research to write humorous articles, letters, and other works. Best known is the Blegdamsvej Faust, performed in April 1932 at the close of one of the Institute's annual conferences. I also focus on the Journal of Jocular Physics, a humorous tribute to Bohr published on the occasions of his 50th, 60th, and 70th birthdays in 1935, 1945, and 1955. Contributors included Léon Rosenfeld, Victor Weisskopf, George Gamow, Oskar Klein, and Hendrik Casimir. I examine their contributions along with letters and other writings to show that they offer a window into some issues in physics at the time, such as the interpretation of complementarity and the nature of the neutrino, as well as the politics of the period.

Freud sobre Fausto: sustituciones de la omnipotencia

Villacañas Berlanga, José Luis

2007-02-01

Full Text Available In Freud’s works, literature has an undeniable significance as well as a remarkable “hermeneutical” funtion, specially the great literature of Classicism. Fictional figures such as Goethe’s Faust give expression to general forces inside the subjectivity. This article argues that there is a very influential Faustian-Universe that goes through Freud’s visions and that psychoanalysis is in debt to some extent with Goethe’s masterpiece, for instance, in its reevaluation of the idea of Bildung, that during the “Age of Enlightenment” had to do with an ethical imperative of making one himself. The faustian adventure can be seen like a seek towards that particular kind of “immortality” to be tasted in-this-world that consists of an unending Will of Power (omnipotence followed by an incessant Wish for Pleasure. But Freud has an important point in common with Goethe: Faust, finally, becomes so entranced by one passing moment that he wishes that things will never change, and this means not only that his life is forfeit to de Devil, but something deeper, namely, that both his expectations for pleasure and wish for omnipotence must stop and have to accept the human idea of Death.Freud puso en valor la capacidad hermenéutica de la literatura, en especial la del clasicismo. Las figuras literarias dan expresión a fuerzas subjetivas que operan en cada indivíduo, como formaciones esenciales de la psique. La literatura es la huella de un proceso de humanización y autoconciencia. Este ensayo analiza la deuda de Freud con Goethe, más específicamente, el cosmos fáustico de Freud, a partir de la recuperación de la idea ilustrada de Bildung o formación del sujeto en tanto trabajo de sí mismo. Fausto es para Freud una fuerza ética representativa del desplazamiento de un ideal de omnipotencia hacia la acción intramundana.

Partindo desta pergunta, neste artigo discute-se a figura do diabo no imaginário europeu no sec. XVI e no Doctor Faustus de Christopher Marlowe. Em seguida são analisados alguns traços principais do diabo goethiano secularizado. O Mefistófeles de Goethe não é o demônio da mitologia cristã e tão pouco representa o grande vilão da peça. Seu autor deixa claro que a responsibilidade pelo mal produzido nas duas partes do Fausto é dos seus personagens humanos.

Full Text Available Otpor is discussed in the text as a complex and contradictory new type of social movement, whose members attempted to contribute to the tradition of enlightened reform of social and political life in Serbia, simultaneously in a highly pragmatic and in a creative, possibly even irresponsible manner. After the introduction, analyzed are popular and media narratives on the characteristics of the movement, dilemmas concerning the founding of the movement and meaning of its key symbols, and the Faustian question of goals and consequences of foreign, in particular American influences. Following is a discussion of strategic (non-violent revolution, calculated victimization and tactical (black campaigns, get-out-the-vote campaign roles of Otpor in the coordinated project of ousting Milosevic. Otpor’s role is then re-interpreted in the frame of the ‘electoral revolution’, developed by Valerie Bunce, Sharon Wolchik and Michael McFoul. An assessment of the transformation of Otpor from an active social movement into an exportable blueprint for non-violent political revolutions is offered in lieu of a conclusion.

2010-12-01

Full Text Available This study aimed to assess the role of endoparasitic infections as another factor of biological pressure on both migratory and local bird species. The occurrence of endoparasites may be considered a sign of undesirable hygienic alterations, causing the shortening of natural fields, compromising the resting area and the habitat nutritional quality. A total of 75 fecal samples were collected at the Campus of the Universidade Federal Rural do Rio de Janeiro (UFRRJ, Brazil, between August 2007 and May 2008, and they were analyzed in a Lugol´s solution by Faust´s technique. Amongst the 82.66% positive samples for enteric parasites, 44% were parasitized by the trichomonads and 5.33% by the Chilomastix enterozoary genera, 52% presented coccidian oocysts, 29.33% showed Entamoeba coli, 37.22% presented Iodamoeba butschlii vegetative forms, and 10.66% were positive for worm eggs. The high prevalence of enteroparasites observed indicates the need of more detailed and frequent evaluations of the environmental sanitary conditions, whose impact seems to be associated to the scarce local hygienic conditions due to the growing anthropization.

Full Text Available Abstract: From 2012 to 2013 were surveyed gastrointestinal parasites from pig farms located in different municpaliyies in the state of Rio de Janeiro. Fecal samples from 790 pigs were collected from the rectum on 88 family farms and 702 farms with industrial production. The samples were subjected to Faust et al., Sheather, Ritchie, Lutz and direct examination faecal techniques. The estimated parasite prevalence was 93.1% in family farms and 59.1% in industrial farms. Balantidium coli, coccidia and Entamoeba sp. were the parasites with the highest frequencies, and the male and female reproductive categories and fatteners pigs the most infected (p<0.05. Trophozoites of B. coli were most evident in stool samples from semi-solid followed by solid and diarrheal consistencies. Strongyles eggs and Trichuris suis have been detected exclusively in family farms. Ascaris suum eggs and Strongyloides ransomi showed low frequency. The high degree of parasitism, especially protozoa, indicates the need to reassess the management of pigs in both types of production.

Local chemical and thermal-hydraulic analysis of U-tube steam generators

Lee, J.Y.; No, H.C.

1990-01-01

In order to know how pH distribution affects corrosion in a U-tube steam generator, a study of the combination of water chemistry and thermal-hydraulic conditions is suggested. A two-fluid (unequal velocity and unequal temperature) formulation is proposed to describe the convective transport of volatile species in each phase, and a spherical bubble model is developed on the basis of the penetration theory to describe the interfacial mass transfer. The thermal-hydraulic local conditions are obtained by the U-tube steam generator design analysis code FAUST which is based on the three-dimensional two-fluid model. The results of the present study are compared with dynamic equilibrium model calculations. This study shows that, in contrast with dynamic equilibrium calculations, the pH is lower in the cold-leg side than in the hot-leg side because of liquid recirculation. Just above the tube sheet, however, the lower void fraction in this region than that in the hot-leg region results in higher pH, which agrees with the prediction of the dynamic equilibrium model.

Intestinal parasitic infections in immunocompromised patients can lead to serious complications when not diagnosed and treated early. This study aimed to investigate the frequency of intestinal parasites in cancer patients undergoing chemotherapy in the South of Brazil. Three fecal samples collected from each patient (73 individuals) were processed by Ritchie and Faust techniques and submitted to specific staining methods for intestinal protozoa. A 61.6% parasite and/or commensal positivity was found. Helminths identified were Ascaris lumbricoides (33.3%), Taenia spp. (6.6%), Strongyloides stercoralis (4.4%) and Trichuris trichiura (2.2%). Among protozoans, Giardia lamblia (26.6%), Cryptosporidium spp. (13.3%) and Cystoisospora belli (4.4%) were identified. The presence of Entamoeba coli, Endolimax nana and Entamoeba hartmanni was also recorded. The results obtained warn of the importance of fecal parasitological diagnosis and the use of specific staining methods for the detection of intestinal parasites in cancer patients. These exams should be regularly requested at the patient's first clinic visit, given the high prevalence found in this study and the possible severity of such conditions for these individuals.

Magnitude and nature of the quadratic electro-optic effect in potassium dihydrogen phosphate and ammonium dihydrogen phosphate crystals

2001-01-01

Measurements of the magnitude and the sign of certain quadratic electro-optic coefficients of potassium dihydrogen phosphate (KDP) and ammonium dihydrogen phosphate (ADP) were made with an actively stabilized Michelson interferometer. The results obtained for these coefficients are, in units of 10 -20 m 2 V -2 (as opposed to literature values of order 10 -18 m 2 V -2 ), as follows: (KDP)g xxxx =-3.4±0.5, g yyxx =-0.2±0.4, and g zzxx =-0.7±0.4; (ADP)g xxxx =-7.4±1.0, g yyxx =-1.7±0.9, and g zzxx =-1.4±0.9. The quadratic Faust--Henry coefficient describing the lattice and the electronic contributions to the quadratic electro-optic effect in KDP and ADP is estimated from our results. These show that the nonlinear susceptibility responsible for the quadratic electro-optic effect in these crystals is due mainly to nonlinear interactions of the low-frequency electric field with the crystal lattice.

In order to identify the helminthic fauna, prevalence, mean intensity of parasitism (MIP, and mean abundance population (MAP, 146 cats from the metropolitan area of Cuiabá, Midwestern Brazil, were necropsied. In 98 these animals, 12 species of helminths were identified, comprising (species, prevalence, MIP, and MAP, respectively: nematodes (Ancylostoma braziliense[50,68% - 53,64 - 27,18], Ancylostoma tubaeforme [10,27% - 3,6 - 0,37],Toxocara cati [4,11% - 28,33 - 1,16],Physaloptera praeputialis [2,05% - 6,67 - 0,14], Capillaria feliscati [3,42% - 7,4 - 0,25], and Aelurostrongylus abstrusus[1,37%]; cestodes (Spirometra mansonoides[4,11% - 2,0 - 0,08], Dipylidium caninum[3,42% - 5,2 - 0,18], and Taenia taeniformis[0,68% - 1,0 - 0,01]; trematodes (Platynosomum fastosum [26,03% - 179,53 - 46,73]; acanthocephalans (Centrorhynchus erraticus [3,42% - 3,2 - 0,11]. Ancylostoma spp., and P. fastosum were the most prevalent with the highest MIP and MAP. We observed the presence of species of helminths with zoonotic potential. This is the first time cats parasitized with Centrorhynchus erraticusare reported in the Americas. That genus is commonly observed in wild animals.

A survey of intestinal parasites in dogs was carried out in a rural region around Cantanhede, in northern Portugal, where 301 dog faecal samples were collected from small-ruminant farms. Saturated salt flotation and formol-ether sedimentation techniques were used. An enquiry was conducted in 234 farms and a risk factor evaluation for zoonotic helminths was determined among the 195 farmers who owned dogs. The overall parasite prevalence in faecal samples of dogs was 58.8%, with specific prevalences for Ancylostomidae being 40.9% followed by species of Trichuris (29.9%), Toxocara (8%), Isospora (4%), Capillaria (0.7%) and Spirometra (0.3%). Taeniidae eggs were present in five samples (1.7%) which were analysed with the polymerase chain reaction (PCR) technique and revealed to be from Taenia sp., and not Echinococcus granulosus. This rural region has a traditional small-farm system, in which farm products are mainly for in-house consumption and home slaughtering is a current practice (57%). Analysis showed home slaughtering to be a statistically significant risk factor for the presence of Ancylostomidae (P= 0.007) and Toxocara sp. (P= 0.049). Owning cattle was found to be a significant risk factor for Taenia sp. (P= 0.031).

An adult free-ranged female maned wolf was rescued from a periurban area subject to anthropogenic disturbances in the Minas Gerais, Brazil. The animal presented poor body condition and anemia. The clinical condition rapidly deteriorated culminating in dead and a necropsy was performed. The main gross lesions were marked anemia and blood content in the intestines accompanied by many types of parasites. The protozoa Rangelia vitalii was identified by histopathological analysis predominantly within the cytoplasm of endothelial cells of capillaries of the small intestine. The lymph nodes, spleen, bone marrow, dermis, lungs and kidney had similar protozoal forms but with mild or moderate intensity. Rangelia vitalii was confirmed by molecular assays. Hepatozoon sp., Leishmania sp., and Entamoeba spp., apparently not related to the clinical signs were also detected. The myriad parasites found in the intestines included nematodes ( Ancylostoma caninum , A . braziliensis ,, Molineus sp., Pterygodermatites sp., and Trichuris sp.), cestodes ( Spirometra sp.) and (acanthocephalans. To our knowledge, R . vitalii was identified in C . brachyurus for the first time. These findings emphasize the fragility of Brazilian ecosystems, especially in disturbed areas, reinforcing the necessity of efforts to preserve these areas and wild carnivores, some of which are threatened with extinction, such as the maned wolf.

Full Text Available The term Eternal-Feminine, or Das Ewig-Weibliche, first appeared in the last verses of the second part of Goethe’s Faust (completed 1832. It, subsequently, became the subject of speculation and a riddle which scholars have been trying to solve ever since. The term gradually came to represent a cultural principle regarding the image of femininity and it reached its Romantic apex, in the 19th Century, when various female archetypes were fused into a singe heroine. The present article aims to explore Isabella’s character in Rossini’s L’Italiana in Algeri in the light of the principle of the Eternal-Feminine. Although Goethe was still in the process of writing the second part of Faust when L’Italiana premiered (1813 in Italy, the cultural principle of the Eternal- Feminine can be used retrospectively in the analysis of Isabella as the central female protagonist of the opera. A thorough reading of her character suggests an aesthetic approach that makes use of certain Romantic aspects of the Eternal-Feminine principle. The present article focuses specifi cally on the Cruda sorte! Amor tiranno! scene and briefl y refers to other scenes as well.La expresión Eterno Femenino (Eternal-Feminine, o Das Ewig-Weibliche, apareció por primera vez en los últimos versos de la segunda parte del Fausto de Goethe (acabado en 1832.

Identifying the clay mineral components of clay materials by staining tests is rapid and simple, but their applicability is restricted because of the mutual interference of the common components of clay materials and difficulties in color determination. The change of color with concentration of the dye is related to the use of colorants as a field test for identifying clay minerals and has been improved over the years to assure the accuracy of the tests (Faust G. T., 1940). The problem of measurement and standardization of color may be solved by combination of colors observed in staining tests with prepared charts of color chips available in the Munsell Book of Color, published by Munsell Color Co. Under a particular set of illumination conditions, a human eye can achieve an approximate match between the color of the dyed clay sample and that of a standard color chip, even though they do have different spectral reflectance characteristics. Experiments were carried out with diffuse reflectance spectroscopy on selected clay samples (three montmorillonite, three kaolinite and one mix-layer clay samples) saturated with different concentration of methylene blue dye solution. Dominant wavelength and purity of the color was obtained on oriented dry samples and calculated by use of the I. C. I. (x, y) - diagram in the region of 400-700 nm (reflectance spectra) without MB and after saturation with different concentrations of MB solutions. Samples were carefully photographed in the natural light environment and processed with user friendly and easily accessible applications (Adobe color CC and ColorHexa encyclopedia) available for android phones or tablets. Obtained colors were compared with Munsell standard color chips, RGB and Hexa color standards. Changes in the color of clay samples in their interaction with different concentration of the applied dye together with application of economical methods can still be used as a rapid fieldwork test.

Dermatophyte fungi are the etiologic agents of skin infections commonly referred to as ringworm. These infections are not dangerous but as a chronic cutaneous infections they may be difficult to treat and can also cause physical discomfort for patients. They are considered important as a public health problem as well. No information is available regarding the efficacy of antifungal agents against dermatophytes in Tehran. Therefore, in this study we evaluated the efficacy of 10 systemic and topical antifungal medications using CLSI broth microdilution method (M38-A). The antifungal agents used included griseofulvin, terbinafine, itraconazole, ketoconazole, fluconazole, voriconazole, clotrimazole, ciclopirox olamine, amorolfine and naftifine.Fifteen different species of dermatophytes which were mostly clinical isolates were used as follows; T. mentagrophytes, T. rubrum, E. floccosum, M. canis, T. verrucosum, T. tonsurans, M. gypseum, T. violaceum, M. ferruginum, M. fulvum, T. schoenleinii, M. racemosum, T. erinacei, T. eriotrephon and Arthroderma benhamiae. The mean number of fungi particles (conidia) inoculated was 1.25 ×10⁴ CFU/mL. Results were read after 7 days of incubation at 28 °C. According to the obtained results,itraconazole and terbinafine showed the lowest and fluconazole had the greatest MIC values for the most fungi tested. Based on the results, it is necessary to do more research and design a reliable standard method for determination of antifungal susceptibility to choose proper antibiotics with fewer side effects and decrease antifungal resistance and risk of treatment failure.

In this study, the prevalence and risk factors for enteroparasites were determined in food handlers from Maringá, Paraná State, southern Brazil. Fecal and subungual materials of 150 street food vendors were analyzed by the methods of Lutz, Faust, and Mello, respectively. A questionnaire on hygiene and sanitary conditions of the workplace and of domicile was applied. The prevalence of enteroparasites was 28%, and the protozoa infection was more expressive (21.3%) than by helminths (6.7%), but without significant difference (p > 0.05). Entamoeba coli was the most frequent species occurring in 15.3%, while the prevalence of protozoa pathogenic was low (Giardia lamblia: 2.7% and Entamoeba histolytica: 0.7%). The subungual material presented negative results. The presence of pets in domiciles has increased twice the risk of infection. The working conditions of the majority of street food vendors were inappropriate. The results highlight the need for more rigorous programs of continuing education, parasitological examination every six months, and health surveillance. In this way, the quality of the service provided to the population can be improved and the transmission of food-borne diseases can be prevented.

Full Text Available Abstract Intestinal parasitic infections in immunocompromised patients can lead to serious complications when not diagnosed and treated early. This study aimed to investigate the frequency of intestinal parasites in cancer patients undergoing chemotherapy in the South of Brazil. Three fecal samples collected from each patient (73 individuals were processed by Ritchie and Faust techniques and submitted to specific staining methods for intestinal protozoa. A 61.6% parasite and/or commensal positivity was found. Helminths identified were Ascaris lumbricoides (33.3%, Taenia spp. (6.6%, Strongyloides stercoralis (4.4% and Trichuris trichiura (2.2%. Among protozoans, Giardia lamblia (26.6%, Cryptosporidium spp. (13.3% and Cystoisospora belli (4.4% were identified. The presence of Entamoeba coli, Endolimax nana and Entamoeba hartmanni was also recorded. The results obtained warn of the importance of fecal parasitological diagnosis and the use of specific staining methods for the detection of intestinal parasites in cancer patients. These exams should be regularly requested at the patient’s first clinic visit, given the high prevalence found in this study and the possible severity of such conditions for these individuals.

Reptiles are growing in popularity as pets.The colonization of reptiles and amphibians by parasites and the resulting disease conditions are the most common problems seen in captive animals.This review focuses on pentastomiasis and sparganosis, important parasitic zoonoses of reptiles and amphibians, respectively, and free living-amoebae. Humans are suitable accidental hosts for some pentastomid species (particularly Armillifer and Porocephalus). In geographical areas with special ethnics, such as in West and Central Africa, and East Asia, 8-45% of the human population can be affected. Usually the larvae are coincidentally found during abdominal surgeries. However, fatalities have been described. Extreme caution is necessary when handling infected reptiles. Ocular or cerebral sparganosis is not uncommonly found in humans in East Asia. This disease is caused by spargana, tapeworm larvae (plerocercoids) of Spirometra sp. The infection occurs when uncooked meat from reptiles or amphibians is applied to wounds or eyes and the parasites migrate directly to human tissue, or by consumption of contaminated food or water. As a consequence of the reptile's predatory behaviour, the full spectrum of endo- and ectoparasites from potential prey animals can be found as transiting parasites in the intestinal tract, e. g. Hymenolepis nana, Cryptosporidium (C.) muris, C parvum or Capillaria hepatica. Occasionally, free-living amoebae are also found in reptile faeces (Acanthamoeba, Naegleria, Hartmanella, Vahlkampfia or Echinamoeba sp.).

The occurrence of waterborne parasites coupled with water parameters at various processing sites of two drinking water treatment plants (A and B) and seven distribution system (DS) sites in Sarawak, Malaysia were studied. Ten liters of water underwent immunomagnetic separation (IMS) technique to detect the presence of Giardia and Cryptosporidium (oo)cysts. The remaining supernatant was used to detect other parasites whilst 50 mL of water sample was each used in the detection of free-living amoebae and fecal coliforms. Sampled water was positive for Giardia (32.9%; 28/85), Cryptosporidium (18.8%; 16/85) followed by Spirometra ova-like (25.9%; 22/85), Blastocystis-like (25.9%; 22/85), nematode larvae-like (8.2%; 7/85) and Taenia ova-like (1.2%; 1/85). Meanwhile, 90.2% (55/61) samples were positive for Acanthamoeba and Naegleria via cultivation and of these, 11 isolates were confirmed as Acanthamoeba genotype T3 (5/7) and T4 (2/7) followed by Naegleria sp. (4/11), Naegleria italica (2/11), Naegleria australiensis (1/11), Naegleria angularis (1/11) and Vahlkampfia sp. (3/11). Cryptosporidium, Acanthamoeba and Naegleria were also detected in one of the seven tested DS sites. Only Giardia and Cryptosporidium showed significant correlations with fluoride and fecal coliforms. These results describe the occurrence of waterborne parasites that will assist key stakeholders in mitigating contamination at the specific sites.

From 14 species of macroalgae (Phaeophyta, Chlorophyta, and Rhodophyta, 1340 samples were obtained identifying seven species as potentially noxious; five of them are new reports for Cuba’s phytobenthos: Prorocentrum belizeanum Faust, P. concavum Fukuyo, P. mexicanum Tafall, Coolia monotis Meunier, and Ostreopsis lenticularis Fukuyo. ANOVA/MANOVA analysis showed significant spatial differences: lower cell abundance near the shoreline adjacent to a river inlet and higher cell abundance in the deepest area. Prorocentrum lima (Ehrenberg Dodge 1975 was found mainly on Phaeophyta followed by Chlorophyta and Rhodophyta. Gambierdiscus toxicus was found mainly on Phaeophyta followed by Rhodophyta and Chlorophyta. All the species reported in the study area were mainly on Padina spp. (Phaeophyta. Acanthophora spicifera (Rhodophyta did not host dinoflagellate species. Environmental conditions in summer (higher temperature, more nutrients, greater water transparency, and low wind intensity are suitable for macroalgae development, which serves as a substrate for potentially harmful dinoflagellates, and possibly the main vector for spreading ciguatera along the coast of Cuba.

Full Text Available This study aimed to investigate the frequency of geohelminthic contamination of public parks and squares in Curitiba, state of Paraná, Brazil, between August and December 2010. A total of 345 samples were collected from 69 sandboxes in different areas and were tested using the Faust, Lutz and Baermann parasitological techniques. Potential risk factors associated with soil contamination were also analyzed. A total of 36% of the samples (124/345 were positive for helminths and 65.2% of the areas (45/69 were classified as contaminated in one or more samples. The most commonly identified parasite eggs were Ancylostoma sp. (14.5%; 50/345; followed by Toxocara sp. (9.6%; 33/345 and the Strongyloidea superfamily (excluding hookworms (2.3%; 8/345. The analysis on the epidemiological risk factors indicated that the presence of dogs and feces in the sandboxes increased the chances of contamination of the site. Use of fences had a protective positive impact that reduced soil contamination. Health education programs should be applied within the community to minimize the risk of human contact with dogs' feces. Use of fencing in these areas is highly recommended to prevent or reduce the users' contact with animal excrement.

Full Text Available A tremendous amount of works have been conducted by psycholinguistics to identify hemisphere processing during second/ foreign language learning, or in other words to investigate the role of the brain hemisphere dominance in language performance of learners. Most of these researches have focused on single words and word pairs (e.g., Anaki et al., 1998; Arzouan et. al., 2007; Faust & Mahal, 2007 or simple sentences (Rapp et al., 2007; Kacinik & Chiarello, 2007, and it has been discovered that there is an advantage of right hemisphere for metaphors and an
advantage of left hemisphere for literal text. But the present research was designed to study Iranian EFL learners' performance in different reading tasks, so there could be differences between the consequences of the former research and the results of the present study due to the context. Here left-brain and right-brain dominance was investigated in 60 individuals (20 right-handed and 10 left-handed male, 20 right-handed and 10 left-handed female via the Edinburg Handedness Questionnaire (EHQ. The research results suggested that the right-handed learners who are supposed to be left-brain outperformed the left-handed ones; and regarding participant's gender, male learners outperformed female learners on reading comprehension test tasks.

Full Text Available Aim: Intestinal parasites are one of the most common problems in sheep production systems. However, the strategies used to eliminate these parasites have not yielded satisfactory results. Therefore, the aim of this study was to determine the effect of five anthelmintics (with different active ingredients on the parasite load in sheep. Materials and Methods: In this study, 107 Rambouillet breed sheep were randomly assigned to five groups. Next, fecal samples were taken directly from the rectum and sent to the laboratory for analysis. We then dewormed each group of sheep using different anthelmintic products: Ivermectin 1%/clorsulon 10%, levamisole 12%, closantel sodium 5%, ivermectin 10%, and closantel 5%/albendazole 3.75% with a dosage corresponding to each sheep. At 15 days post-treatment, we took fecal samples and performed a coproparasitoscopic study, using the Faust flotation technique to assess the presence or absence of parasite eggs and the McMaster technique to quantify eggs. Results: Ivermectin/clorsulon was more effective in eliminating parasites than other anthelmintics used, especially in Haemonchus spp. Conclusion: The results of this study indicate that using ivermectin/clorsulon decreases the number of eggs in feces and is one alternative in controlling parasites in sheep, leading to a reduction in the incidence of health problems, and consequently, improved productivity.

In Cambodia, intestinal parasitic infections are prevalent in humans and particularly in children. Yet, information on potentially zoonotic parasites in animal reservoir hosts is lacking. In May 2012, faecal samples from 218 humans, 94 dogs and 76 pigs were collected from 67 households in Dong village, Preah Vihear province, Cambodia. Faecal samples were examined microscopically using sodium nitrate and zinc sulphate flotation methods, the Baermann method, Koga Agar plate culture, formalin-ether concentration technique and Kato Katz technique. PCR was used to confirm hookworm, Ascaris spp., Giardia spp. and Blastocystis spp. Major gastrointestinal parasitic infections found in humans included hookworms (63.3%), Entamoeba spp. (27.1%) and Strongyloides stercoralis (24.3%). In dogs, hookworm (80.8%), Spirometra spp. (21.3%) and Strongyloides spp. (14.9%) were most commonly detected and in pigs Isospora suis (75.0%), Oesophagostomum spp. (73.7%) and Entamoeba spp. (31.6%) were found. Eleven parasite species were detected in dogs (eight helminths and three protozoa), seven of which have zoonotic potential, including hookworm, Strongyloides spp., Trichuris spp., Toxocara canis, Echinostoma spp., Giardia duodenalis and Entamoeba spp. Five of the parasite species detected in pigs also have zoonotic potential, including Ascaris spp., Trichuris spp., Capillaria spp., Balantidium coli and Entamoeba spp. Further molecular epidemiological studies will aid characterisation of parasite species and genotypes and allow further insight into the potential for zoonotic cross transmission of parasites in this community.

The present study was conducted to determine the prevalence of helminth eggs excreted in the faeces of stray cats, dogs and in soil samples. A total of 505 fresh samples of faeces (from 227 dogs and 152 cats) and soil were collected. The egg stage was detected via microscopy after the application of formalin-ether concentration technique. Genomic DNA was extracted from the samples containing hookworm eggs and used for further identification to the species level using real-time polymerase chain reaction coupled with high resolution melting analysis. Microscopic observation showed that the overall prevalence of helminth eggs among stray cats and dogs was 75.7% (95% CI = 71.2%-79.9%), in which 87.7% of dogs and 57.9% of cats were infected with at least one parasite genus. Five genera of heliminth eggs were detected in the faecal samples, including hookworms (46.4%), Toxocara (11.1%), Trichuris (8.4%), Spirometra (7.4%) and Ascaris (2.4%). The prevalence of helminth infections among stray dogs was significantly higher than that among stray cats (p dog hookworm, Ancylostoma caninum, was also detected among cats, which is the first such occurrence reported in Malaysia till date. This finding indicated that there was a cross-infection of A. caninum between stray cats and dogs because of their coexistent within human communities. Taken together, these data suggest the potential role of stray cats and dogs as being the main sources of environmental contamination as well as for human infections.

We collected fecal samples from 500 dogs and 300 cats from an animal refuge in Nakhon Nayok Province, Thailand to test for gastrointestinal protozoa and helminths using a formalin-ether concentration technique. The overall prevalence of parasites in stool from dogs was 36.2% (181/500), 35.7% (177/500) had helminths and 2.8% (14/500) had protozoa. The helminths were: hookworm (30.6%), Trichuris vulpis (16.0%), Toxocara canis (6.6%), Hymenolepis diminuta (1.2%), Spirometra mansoni (0.6%), and Dipylidium caninum (0.2%). Giardia duodenalis (2.8%) was found in the stool of dogs. The overall prevalence of parasites in stool from cats was 44.3% (133/300), 43.3% (130/300) were helminths and 6.0% (18/300) were protozoa. The helminths were hookworm (34.7%), T. cati (9.7%), S. mansoni (4.0%), Platynosomum fastosum (2.7%), Strongyloides sp (0.7%), and Echinostoma sp (0.3%). Two species of protozoa, Isospora sp (5.7%) and G. duodenalis (0.3%) were found in the stool of cats. Two percent of dogs and 5.0% of cats had mixed protozoan and helminthic infections. Dogs with double, triple, and quadruple helminthic infections were found at rates of 22.0%, 2.8%, and 0.2%, respectively. Cats with double and triple helminthic infections were found at rates of 9.7% and 1.0%, respectively. Quadruple helminthic infections were not found in cats, and double protozoan infections were not found in either dogs or cats.

Full Text Available The paper represents an attempt to channel polemical exchanges concerning the process of democratization in Serbia into the frames of scientific dialogue which is considered here to be a more productive genre of scientific communication than are polemics. The most important issue addressed concerns providing adequate theoretical explanations of the ′revolution of October the 5th′ and of the roles that the student / popular movement ′Otpor′ played in it. According to the thesis defended by the author, the models of ′waves of democratization′ and of ′electoral revolution′ offer an adequate theoretical frame for the discussion of such problems. Among the questions that are addressed in the paper are the following: how much can relying on external sources blur the understanding of local processes; what is the difference between ′exported/imported′ and ′electoral revolutions′; how should one situate the Serbian ′October revolution′ in the waves of post communist democratization; what are the particularities of the Serbian electoral revolution compared to other ′colored revolutions′; how should the respective roles of external and internal players in the Serbian case be evaluated; what are the particularities of projects of democratization based on synergy as opposed to those based on hierarchy and relations of rower what binds together the strategy of non-violent resistance, proactive politics and Otpor’s ′Plan B′; finally, can a direct link between the amount of foreign assistance and the degree of loss of control over the results of political reform be presupposed. In the final section, offered is an assessment of the negative and positive aspects of Otpor’s political legacy as well as an attempt to link this legacy with an understanding of the ′dynamics of hope′ as a political project on which Otpor worked systematically.

Full Text Available Economic growth has become a fetish, as it is believed to yield many benefits to society. It has its origins in the Enlightenment ideal of progress through science, technology and a free market economy. J.W. Goethe anticipated the problems of such progress in his poem Faust, especially its second part. Binswanger interprets Goethe’s view on the modern economy as a form of alchemy, an attempt to master time through the invention of monetary capital. Keynes’s views on progress and liquidity are compatible with this analysis. The problems, evoked by the uncritical application of scientific technology so as to increase material welfare, have given rise to a dialectic between business seeking growth and those concerned about its effects, especially on ecology. Sustainable development is an outcome of this dialectic, without abandoning it. Others, particularly those advocating décroissance [de-growth], reject the concepts underlying growth. The ideology underlying this is a combination of technicism and economism. A spiritual revolution is called for to break the hold of this ideology on society, with a change from the metaphor of the world as a machine to that of a garden-city. It is suggested that working groups should analyse the various proposals for change from the perspective of the garden-city metaphor.

Lejeune, J

Technical development has produced a curious phenomenon, the ebbing of the moral imperative of reproduction. After 2000 years of fight against diseases and death, the respect for life has declined threatening the destruction of Western civilization and family by destroying unborn babies via abortion. Artificial in vitro experimentation can potentially lead to elimination of very young, old, or sick people. Dr. Bernard Nathanson in his book "Aborting America" called abortion infanticide, one of the most abominable crimes. The beginning of life start at conception as shown by recent extra-corporal, in vitro fertilization resulting in a viable fetus, as in the case of Luisa Brown who was conceived in a tube by Drs. Edwards' and Steptoe's technique. The creation of human embryo banks and experimentation on human embryos amount to biological pronography. Respect for the human species and reproduction should manifest itself in the fight against sterility and genetic diseases, such as muscular dystrophy, hemophilia, Down's syndrome, and Huntington's chorea. The fight against AIDS and the elimination of the risk of contracting it by contaminated blood is also a medical priority. In the end, the question still remains: can science itself save the world without moral imperatives, is not the dilemma of Faust and the vileness of Mephistopheles conjured with the nuclear experience and human experimentation.

Full Text Available By consulting monographies, musicological studies, specialty articles about the personality of romantic musician Hector Berlioz and implicitly linked to the relevance of his significant opera, one discovers researchers’ constant preoccupation for historical, stylistic, analytical, hermeneutical comments upon aspects related to established scores (the Fantastic, Harold in Italy symphonies, dramatic legend The Damnation of Faust, dramatic symphony Romeo and Juliet, the Requiem, etc.. Out of his compositions, it is remarkable that the cycle Les nuits d´été was rarely approached from a musicological point of view, despite the fact that it is an important opus, which inaugurates the genre of the orchestral lied at the end of the 19th century and the beginning of last century. In this study, we set out to compose as complete as possible an image of this work, both from an analytic-stylistic point of view by stressing the text-sound correspondences and, above all, from the perspective of its reception at a didactic level, by promoting the score in the framework of listening sessions commented upon as part of the discipline of the history of music. In what follows, I shall argue that the cycle of orchestral lieder Les nuits d´été by Hector Berlioz represents a work of equal importance to established opera.

Writing is often used as a tool for learning. However, empirical support for the benefits of writing-to-learn is mixed, likely because the literature conflates diverse activities (e.g., summaries, term papers) under the single umbrella of writing-to-learn. Following recent trends in the writing-to-learn literature, the authors focus on the underlying cognitive processes. They draw on the largely independent writing-to-learn and cognitive psychology learning literatures to identify important cognitive processes. The current experiment examines learning from 3 writing tasks (and 1 nonwriting control), with an emphasis on whether or not the tasks engaged retrieval. Tasks that engaged retrieval (essay writing and free recall) led to better final test performance than those that did not (note taking and highlighting). Individual differences in structure building (the ability to construct mental representations of narratives; Gernsbacher, Varner, & Faust, 1990) modified this effect; skilled structure builders benefited more from essay writing and free recall than did less skilled structure builders. Further, more essay-like responses led to better performance, implicating the importance of additional cognitive processes such as reorganization and elaboration. The results highlight how both task instructions and individual differences affect the cognitive processes involved when writing-to-learn, with consequences for the effectiveness of the learning strategy.

Sparganosis is a rare tissue-parasitic infestation caused by a plerocercoid tapeworm larva(sparganum), genus Spirometra. The most common clinical presentation of sparganosis is a palpable subcutaneous mass or masses. Fifteen simple radiographs and 10 ultrasosnograms of 17 patients with operatively verified subcutaneous sparganosis were retrospectively analyzed to find its radiologic characteristics for preoperative diagnosis of sparganosis. The location of the subcutaneous sparganosis were lower extremity, abdominal wall, breast, inguinal region and scrotum in order of frequency. The simple radiographs showed linear or elongated calcification with or without nodular elongated shaped soft tissue mass shadows in 8 patients, soft tissue mass shadow only in 2 patients and lateral abdominal wall thickening in 1 patient. But no specific findings was noted in 4 patients with small abdominal and inguinal masses. We could classify the subcutaneous sparganosis by ultrasound into 2 types: one is long band-like hypoechoic structures, corresponding to the subcutaneous tunnel-like tracks formed by migration of sparganum larva and the order is elongated or ovoid hyperechoic nodules, representing granulomas. Long band-like hypoechoic structures within or associated with mixed echoic granulomatous masses were noted in 6 patients and elongated or ovoid hypoechoic mass or masses were noted in 4 patients. In conclusion, sparganosis should be considered when these radiologic findings-irregular linear calcifications on simple radiograph and long band-like hypoechoic structures on ultrasonography, corresponding to the subcutaneous tunnel-like tracks formed by migration of sparganum larva are noted in the patients who have subcutaneous palpable mass or masses. And radiologic examination especially ultrasonography is very helpful to diagnose sparganosis.

Dermatomycoses due to contact with pets and livestock frequently affect children and young adults. Zoophilic dermatophytes are the main important causative agents. It has long been known that the often high inflammatory dermatophytoses of the skin and the scalp are caused mostly by Microsporum canis. Due to an absence of an obligation for reporting fungal infections of the skin to the Public Health Office in Germany, an unnoticed but significant change in responsible pathogens has occurred. Today an increasing number of infections due to zoophilic strains of Trichophyton interdigitale (formerly Trichophyton mentagrophytes) and Trichophyton species of Arthroderma benhamiae are found. The latter mentioned dermatophyte is the anamorph species of the teleomorph Arthroderma benhamiae, which originally was isolated in the Far East (Japan). Source of infection of these dermatophytes are small rodents, in particular guinea pigs. These animals are bought in pet shops by the parents of those children who later are affected by the fungal infection. The coincidental purchase of the relevant fungal pathogen is not obvious to the parents. As a consequence, highly contagious dermatophytoses occur, often tinea capitis sometimes with kerion formation. Further dermatophytes should be considered as cause of a zoophilic dermatomycosis. Both Trichophyton verrucosum, the cause of the ringworm in cattle, and Trichophyton erinacei following contact to hedgehogs are worthy of note. Yeasts cannot be ignored as cause of dermatomycosis, especially Malassezia pachydermatis, the only non-lipophilic species within the genus Malassezia, which can be transferred from dog to men. Cryptococcus neoformans also comes from animal sources. The mucous yeast occurs in bird's dropping, and it causes both pulmonary and central nervous system infections, but also primary and secondary cutaneous cryptococcosis in immunocompromised patients (HIV/AIDS) as possible consequence after contact to these animals.

Red foxes (Vulpes vulpes (L.)) are widespread across Europe, tolerant of synanthropic ecosystems, and susceptible to diseases potentially shared with humans and other animals. We describe flea fauna on red foxes in Romania, a large, ecologically diverse country, in part because fleas may serve as an indicator of the risk of spillover of vector-borne disease. We found 912 individual fleas of seven species on the 305 foxes assessed, for an infestation prevalence of 49.5%. Mean flea load per fox was 5.8 (range 0-44 fleas), and flea detections were most abundant in fall and early spring. Fleas included generalists (Ctenocephalides canis (Curtis), 32.6% of all fleas), Ct. felis (Bouché, 0.1%), and Pulex irritans L. (29.9%), the fox specialist Chaetopsylla globiceps (Taschenberg, 32.5%), mesocarnivore fleas Paraceras melis Walker (3.2%) and Ch. trichosa Kohaut (1.5%), and the small mammal flea Ctenophthalmus assimilis (Taschenberg, 0.1%), which is rarely or never reported from carnivores. There were significantly more female than male Ch. globiceps, Ct. canis, and Pu. irritans, and these three species were the most broadly distributed geographically. Diversity indices suggested reduced diversity in mountainous areas above 700 m. When compared to other flea studies on foxes in Europe, Romania had flea diversity near the median of reports, which was unexpected given Romania's high ecological diversity. Notably absent prey specialists, compared to other studies, include Archaeopsylla erinacei (Bouché) and Spilopsyllus cuniculi (Dale). Further studies of possible disease agents in fox fleas could help elucidate possible risks of vector-borne disease in foxes, domestic animals, and humans as well. © The Authors 2017.

In operas and ballets they were also respected in some extent, but the pictorial, sometimes independent value of their scenic work, although inspired by music, arouse opposing questions among the musical critics, who could not accept their too bright colors which once conquered Paris in the scenic interpretation of Leon Bakst or Nikolai Roerich. To avoid resistance of Belgrade critics the couple decided to leave Yugoslav capital for Italy where they continued successfully their artistic career.

Rock stresses associated with burial of nuclear waste

International Nuclear Information System (INIS)

Voight, B.

1977-01-01

Rock stress changes related to long-term deep storage of nuclear waste involve thermoelastic and pore fluid pressure changes associated with excavation and heating. Computer models are being examined to assess the question of thermally-induced fracturing in storage rock surrounding radioactive waste containers. Stresses are evaluated in three dimensions, employing elastic-plastic finite element codes. Potential failure conditions are expressed in terms of ''effective stresses,'' and force and thermal fields are incremented to produce an appropriate load path. In general, heating in vicinity of waste containers produces a zone of high compression bonded by a zone of circumferential and axial tension. (At this conference an analogous case of thermal stresses was documented and illustrated for larger-scale temperature domains associated with geothermal areas in Iceland.) Fractures are possible in radial directions as well as perpendicular to the axis of the cylindrical heat source. In addition, the mechanical effect of a vapor pulse will be explored by a two-phase numerical fluid transport model used in conjunction with mechanical finite element models. This portion of the work, being conducted jointly with C. R. Faust and J. W. Mercer of the US Geological Survey, should provide a preliminary appreciation of the possible effect of phase changes on fracturing of burial sites. Preliminary work suggests the possibility of establishing design criteria (e.g., design burial depth, depth of canister below storage vault) in order to minimize problems of potential rock fracture

Internationalization at Harvard

Full Text Available The aim of this essay is to describe internationalization at Harvard University. Founded by European colonists in 17th century New England, Harvard has historic international roots. By the mid 1900’s it had become an international powerhouse attracting top students, academics and scientists from around the world. Yet, the University is international almost by default as it has reacted to world affairs. Looking toward the future, President Drew Faust has outlined a strategy to become “intentionally global”. One model, begun ten years ago, serves as an example for the future. In 2002 the University established its first overseas office designed to represent the entire institution. The theory was that a modest local infrastructure would encourage students and faculty to expand international collaborations and make a difference in the region benefiting from this presence. The results have been highly successful. The Regional Office in Santiago Chile, representing Argentina, Bolivia, Chile, Peru, and Uruguay, has catalyzed engagement of over 3000 faculty and students in the last ten years. Over 50 significant collaborative research programs have benefitted thousands of preschool children, pioneered new approaches to disaster relief, improved health care, revolutionized public housing, and led to scientific breakthroughs. This model of a small physical footprint exerting large academic influence will be one of the central strategies as Harvard looks toward the future. DOI: 10.18870/hlrc.v3i2.117

Dogs have been bred since ancient times for companionship, hunting, protection, shepherding and other human activities. Some canine helminth parasites can cause significant clinical diseases in humans as Opisthorchis viverrini causing cholangiocarcinoma in Southeast Asian Countries. In this study, socio-cultural questionnaire, canine parasitological analysis, necropsy, parasite molecular confirmation and dog roaming data were evaluated in Savannakhet, Lao-PDR, a typical Mekong Basin area. Dog owners comprised 48.8% of the studied population, with 61.2% owning one dog, 25.1% 2 dogs, 8.5% 3 dogs and 1.8% owning more than 4 dogs. Data from GPS logger attached to dogs showed they walked from 1.4 to 13.3 km per day, covering an area of 3356.38m2 average, with a routine of accessing water sources. Thirteen zoonotic helminth species were observed. Causative agents of visceral and cutaneous larva migrans occurred in 44.1% and 70% of the samples respectively. Spirometra erinaceieuropaei was detected in 44.1% of samples. Importantly, O. viverrini was found in 8.8% of samples. Besides the known importance of dogs in the transmission of Ancylostoma spp., Toxocara spp. and S. erinaceieuropaei, the observed roaming pattern of dogs confirmed it as an important host perpetuating O. viverrini in endemic areas; their routine access to waterbodies may spread O. viverrini eggs in a favorable environment for the fluke development, facilitating the infection of fishes, and consequently infecting humans living in the same ecosystem. Therefore, parasitic NTDs control programs in humans should be done in parallel with parasite control in animals, especially dogs, in the Mekong River basin area.

Full Text Available Blastocystis homins is a protozoan that causes an intestinal infection known as human blastocystosis. This infection is diagnosed by means of parasitological examination of stools and by permanent staining techniques. The present study was developed to evaluate the frequency of Blastocystis hominis infection among inhabitants of the Araraquara region, State of São Paulo, and to compare different methods for investigating this protozoan in feces samples. Evaluations on 503 stool samples were performed by means of direct fresh examination and using the techniques of Faust et al., Lutz and Rugai et al. In addition, the iron hematoxylin, trichrome and modified Kinyoun staining techniques were used. Out of the 503 samples examined, 174 (34.6% were found to be positive for the presence of intestinal parasites. The most frequent protozoa and helminths were Entamoeba coli (14.6% and Strongyloides stercoralis (6.7%, respectively. Blastocystis hominis was present in 23 (4.6% fecal samples, with a predominately pasty consistency and without characterizing a condition of diarrhea. Despite the low frequency of Blastocystis hominis found in the Araraquara region, compared with other regions of Brazil, it is important to perform laboratory diagnostic tests for this protozoan. Its finding in fecal material is indicative of food and drinking water contamination. Since the transmission route for this parasite is accepted to be oral-fecal, this implies that the population needs guidance regarding hygiene and basic sanitation measures as a means for controlling health problems caused by enteroparasites.Blastocystis hominis é um protozoário, causador de infecção intestinal denominada blastocistose humana, cujo diagnóstico é realizado pelo exame coproparasitológico e por meio de técnicas de coloração permanente.

Full Text Available Abstract Background Cerebral sparganosis in children is an extremely rare disease of central nervous system, and caused by a tapeworm larva from the genus of Spirometra. In this study, we discussed and summarized epidemiological, clinical and MR imaging characteristics of eighteen children with cerebral sparganosis for a better diagnosis and treatment of the disease. Methods Eighteen children with cerebral sparganosis verified by pathology, serological tests and MR presentations were retrospectively investigated, and the epidemiologic and clinical characteristics of the disease were studied. Results Twenty-seven lesions were found in the eighteen children. Twelve lesions in twelve patients were solitary while the lesions in the rest six patients were multiple and asymmetrical. The positions of the lesions were: seven in frontal, eleven in parietal, four in temporal and two in occipital lobes, one in basal ganglia, one in cerebella hemisphere and one in pons. The lesions were presented as slight hypointensity on T1-weighted images but moderate hyperintensity on T2-weighted images with perilesional brain parenchyma edema. Enhanced MR scans by using Gadopentetic Acid Dimeglumine Salt were performed in the patients, and the images demonstrated abnormal enhancements with the patterns of a peripheral ring, or a tortuous beaded, or a serpiginous tubular shape. Follow-up MR scans were preformed for eight patients, and three out of the eight cases exposed migrations and changes in shapes of the lesion areas. Conclusions The MR presentations in our study in general were similar to those in previous studies. However serpiginous tubular and comma-shaped enhancements of lesions have not been previously reported. The enhanced MR imaging and follow-up MR scans with the positive results from serological tests are the most important methods for the clinical diagnosis of cerebral sparganosis in children.

Full Text Available BACKGROUND: Food-borne helminthiases (FBHs have become increasingly important due to frequent occurrence and worldwide distribution. There is increasing demand for developing more sensitive, high-throughput techniques for the simultaneous detection of multiple parasitic diseases due to limitations in differential clinical diagnosis of FBHs with similar symptoms. These infections are difficult to diagnose correctly by conventional diagnostic approaches including serological approaches. METHODOLOGY/PRINCIPAL FINDINGS: In this study, antigens obtained from 5 parasite species, namely Cysticercus cellulosae, Angiostrongylus cantonensis, Paragonimus westermani, Trichinella spiralis and Spirometra sp., were semi-purified after immunoblotting. Sera from 365 human cases of helminthiasis and 80 healthy individuals were assayed with semi-purified antigens by both a protein microarray and the enzyme-linked immunosorbent assay (ELISA. The sensitivity, specificity and simplicity of each test for the end-user were evaluated. The specificity of the tests ranged from 97.0% (95% confidence interval (CI: 95.3-98.7% to 100.0% (95% CI: 100.0% in the protein microarray and from 97.7% (95% CI: 96.2-99.2% to 100.0% (95% CI: 100.0% in ELISA. The sensitivity varied from 85.7% (95% CI: 75.1-96.3% to 92.1% (95% CI: 83.5-100.0% in the protein microarray, while the corresponding values for ELISA were 82.0% (95% CI: 71.4-92.6% to 92.1% (95% CI: 83.5-100.0%. Furthermore, the Youden index spanned from 0.83 to 0.92 in the protein microarray and from 0.80 to 0.92 in ELISA. For each parasite, the Youden index from the protein microarray was often slightly higher than the one from ELISA even though the same antigen was used. CONCLUSIONS/SIGNIFICANCE: The protein microarray platform is a convenient, versatile, high-throughput method that can easily be adapted to massive FBH screening.

Full Text Available The present study was conducted to determine the prevalence of helminth eggs excreted in the faeces of stray cats, dogs and in soil samples. A total of 505 fresh samples of faeces (from 227 dogs and 152 cats and soil were collected. The egg stage was detected via microscopy after the application of formalin-ether concentration technique. Genomic DNA was extracted from the samples containing hookworm eggs and used for further identification to the species level using real-time polymerase chain reaction coupled with high resolution melting analysis. Microscopic observation showed that the overall prevalence of helminth eggs among stray cats and dogs was 75.7% (95% CI = 71.2%-79.9%, in which 87.7% of dogs and 57.9% of cats were infected with at least one parasite genus. Five genera of heliminth eggs were detected in the faecal samples, including hookworms (46.4%, Toxocara (11.1%, Trichuris (8.4%, Spirometra (7.4% and Ascaris (2.4%. The prevalence of helminth infections among stray dogs was significantly higher than that among stray cats (p < 0.001. Only three genera of helminths were detected in soil samples with the prevalence of 23% (95% CI = 15.1%-31%, consisting of hookworms (16.6%, Ascaris (4% and Toxocara (2.4%. The molecular identification of hookworm species revealed that Ancylostoma ceylanicum was dominant in both faecal and soil samples. The dog hookworm, Ancylostoma caninum, was also detected among cats, which is the first such occurrence reported in Malaysia till date. This finding indicated that there was a cross-infection of A. caninum between stray cats and dogs because of their coexistent within human communities. Taken together, these data suggest the potential role of stray cats and dogs as being the main sources of environmental contamination as well as for human infections.

Wildlife remains an important source of zoonotic diseases for the most vulnerable groups of humans, primarily those living in rural areas or coexisting with forest. The Upper Paraná Atlantic forest of Misiones, Argentina is facing ongoing environmental and anthropogenic changes, which affect the local biodiversity, including the bush dog (Speothos venaticus), a small canid considered Near Threatened globally and Endangered locally. This project aimed to expand the knowledge of zoonotic parasites present in the bush dog and the potential implications for human health and conservation medicine. From May to August 2011, a detection dog located 34 scats that were genetically confirmed as bush dog and georeferenced to northern Misiones. Of these 34 scats, 27 had sufficient quantity that allowed processing for zoonotic parasites using morphological (sedimentation and flotation) and antigen (coproantigen technique) analyses. Within these 27 scats, we determined that the parasitic prevalence was 63.0% (n = 17) with 8 (47.1%) having mixed infections with 2-4 parasitic genera. No significant differences (p > 0.05) between sampling areas, sex, and parasite taxa were found. We were able to summarize the predominant nematodes (Ancylostoma caninum, Toxocara canis, and Lagochilascaris spp.), cestodes (Taenia spp. and Spirometra spp.), and apicomplexa (Cystoisospora caninum) found in these bush dogs. With the copro-ELISA technique, 14.8% (n = 4) of the samples were positive for Echinococcus spp. This study represents the first comprehensive study about parasitic fauna with zoonotic potential in the free-ranging bush dog. This information combined with the innovative set of techniques used to collect the samples constitute a valuable contribution that can be used in control programs, surveillance of zoonotic diseases, and wildlife conservation, both regionally and across the bush dog's broad distribution.

This paper is intended to provide a critical overview of experimental and clinical research documenting problems in figurative language processing in atypical populations with a focus on the Autistic Spectrum. Research in the comprehension and processing of figurative language in autism invariably documents problems in this area. The greater paradox is that even at the higher end of the spectrum or in the cases of linguistically talented individuals with Asperger syndrome, where structural language competence is intact, problems with extended language persist. If we assume that figurative and extended uses of language essentially depend on the perception and processing of more concrete core concepts and phenomena, the commonly observed failure in atypical populations to understand figurative language remains a puzzle. Various accounts have been offered to explain this issue, ranging from linking potential failure directly to overall structural language competence (Norbury, 2005; Brock et al., 2008) to right-hemispheric involvement (Gold and Faust, 2010). We argue that the dissociation between structural language and figurative language competence in autism should be sought in more general cognitive mechanisms and traits in the autistic phenotype (e.g., in terms of weak central coherence, Vulchanova et al., 2012b), as well as failure at on-line semantic integration with increased complexity and diversity of the stimuli (Coulson and Van Petten, 2002). This perspective is even more compelling in light of similar problems in a number of conditions, including both acquired (e.g., Aphasia) and developmental disorders (Williams Syndrome). This dissociation argues against a simple continuity view of language interpretation. PMID:25741261

Full Text Available Las hortalizas aportan grandes beneficios para la salud debido a sus innumerables propiedades alimenticias; sin embargo, existe una gran variedad de factores que ponen en riesgo la calidad sanitaria de las mismas constituyéndose en vehículos para enfermedades de transmisión alimentaria (ETA. Por ello, se decidió evaluar la calidad microbiológica y parasitológica de dos hortalizas, lechuga (Lactuca sativa y cilantro (Coriandrum sativum expendidas en la Parroquia Santa Rita del Municipio Francisco Linares Alcántara (Aragua, Venezuela. Se analizaron un total de 20 muestras, 10 de cilantro y 10 de lechuga; la determinación microbiológica se realizó por la técnica del Número Más Probable y el análisis parasitológico, mediante observación directa, tinción de Kinyoun y la técnica de Faust. Los resultados mostraron la presencia de coliformes totales (1,1x104 NMP/g en el 100 % de las muestras. No se evidenció coliformes fecales en ninguna de las muestras. En relación al análisis parasitológico, se identificaron protozoarios intestinales, con mayor prevalencia de Blastocystis spp. y menor en helmintos. Los resultados demuestran el peligro potencial que representa el consumo de hortalizas frescas contaminadas para la salud pública. Se debe concientizar a la población sobre medidas sanitarias preventivas que deben aplicar antes del consumo e implementar medidas de control que mejoren las condiciones higiénicas en la cadena de comercialización.

The prevalence and distribution of soil and water samples contaminated with enteroparasites of humans and animals with zoonotic potential (EHAZP) in Apucaraninha Indigenous Land (AIL), southern Brazil, was evaluated. An environmental survey was conducted to evaluate the presence of parasitic forms in peridomiciliary soil and associated variables. Soil samples were collected from 40/293 domiciles (10 domiciles per season), from November 2010 to June 2011, and evaluated by modified methods of Faust et al. and Lutz. Analyses of water from seven consumption sites were also performed. The overall prevalence of soil samples contaminated by EHAZP was 23.8 %. The most prevalent parasitic forms were cyst of Entamoeba spp. and eggs of Ascaris spp. The highest prevalence of contaminated soil samples was observed in winter (31 %). The probability map obtained with geostatistical analyses showed an average of 47 % soil contamination at a distance of approximately 140 m. The parasitological analysis of water did not detect Giardia spp. or Cryptosporidium spp. and showed that all collection points were within the standards of the Brazilian law. However, the microbiological analysis showed the presence of Escherichia coli in 6/7 sampled points. Despite the low level of contamination by EHAZP in peridomiciliar soil and the absence of pathogenic protozoa in water, the AIL soil and water (due to the presence of fecal coliforms) are potential sources of infection for the population, indicating the need for improvements in sanitation and water treatment, in addition periodic treatment of the population with antiparasitic.

Foodborne illnesses have been a growing concern to the governments, international organizations and consumers, mainly regarding the damages they cause to human health. This issue is the result of the substitution of imported food habits, which enable the consumption of raw fish or wrongly prepared fish. Among the emergent parasitic zoonosis, the Fagicolose stands out. It is transmitted by Phagicola longa, a trematoda of great importance in public health and responsible for high percentages of Mugilidae infections, that is able to produce humans' parasitism. In this experiment, the studies were focused to the radio sensibility of metacercaria of Phagicola longa exposed to a treatment with ionizing radiation (gamma rays and electron beams) and the sensibility to freezing, in artificially infected fish. Some data were acquired regarding the occurrence of Phagicola longa in mullets bought in the local market, the freezer temperature of 10 domestic refrigerators, and the origin and preservation of the mullets in some Japanese-type restaurants in Sao Paulo. The results indicated more effectiveness in the treatment with the electron accelerator, as well as with the freezing at the temperature of-16 deg C. (author)

Plerocercoid growth factor (PGF), a human growth hormone (hGH) analogue produced by the tapeworm Spirometra mansonoides, has direct insulin-like action in adipose tissue of normal rats in vitro

The metabolic actions of GH can be divided into acute (insulin-like) and chronic (lipolytic/anti-insulin). The insulin-like actions of GH are most readily elicited in GH-deficient animals as GH induces resistance to its own insulin-like action. Like GH, PGF stimulates growth and cross-reacts with anti-hGH antibodies. Independent experiments were conducted comparing the direct actions of PGF to insulin or hGH in vitro. Insulin-like effects were determined by the ability of PGF, insulin or hGH to stimulate [U- 14 C]glucose metabolism in epidydimal fat pads from normal rats and by inhibition of epinephrine-stimulated lipolysis. Direct stimulation of lipolysis was used as anti-insulin activity. To determine if PGF competes for insulin or GH receptors, adipocytes (3 x 10 5 cells/ml) were incubated with either [ 125 I]insulin or [ 125 I]hGH +/- PGF, +/- insulin or +/- hGH. PGF stimulated glucose oxidation and 14 C-incorporation into lipids. Insulin, hGH and PGF inhibited lipolysis (33%, 29% and 34%, respectively). Adipose tissue was very sensitive to the lipolytic effect of hGH but PGF was neither lipolytic nor did it confer refractoriness to its insulin-like action. PGF bound to GH but not to insulin receptors. Therefore, PGF had direct insulin-like effects but did not stimulate lipolysis in tissue from normal rats in vitro

Red foxes (Vulpes vulpes) are the most common and widely distributed wild carnivore worldwide. These predators harbour a wide range of parasites, many of which may have important conservation, agricultural and zoonotic repercussions. This project investigated the occurrence of helminth parasites from the intestines of 147 red foxes across 14 sampling localities of southwest Western Australia. Helminth parasites were detected in 58% of fox intestines: Dipylidium caninum (27.7% of foxes), Uncinaria stenocephala (18.2%), Toxocara canis (14.9%), Spirometra erinaceieuropaei (5.4%), Toxascaris leonina (4.7%), Taenia serialis (1.4%), Taenia hydatigena (0.7%), unidentified Taenia spp. (4.1%), Brachylaima cribbi (0.7%), Plagiorchis maculosus (0.7%) and an Acanthocephalan; family Centrorhynchidae (2.1%). Importantly, two cestodes of agricultural significance, Echinococcus granulosus and Taenia ovis, were not detected in red foxes in this study, despite the presence of suitable intermediate hosts in the diets of these animals. Parasite richness varied from 1–3 species per host, with average parasite number varying from 1–39 worms (across all helminth species). Regression analyses indicated that the presence of four helminth parasites was related to various environmental factors. The presence of S. erinaceieuropaei (p < 0.001), T. leonina (p < 0.01) and U. stenocephala (p < 0.01) was positively associated with average relative humidity which may affect the longevity of infective stages in the environment. The presence of S. erinaceieuropaei and U. stenocephala (p < 0.001) was positively associated with 5-y-average minimum temperature which could reflect poor survival of infective stages through cold winter conditions. The presence of T. canis and U. stenocephala (p < 0.001) was positively associated with the percentage cover of native vegetation at each sampling location, which is likely to reflect transmission from native prey species acting as paratenic hosts

The catholic taste of broad tapeworms - multiple routes to human infection.

Broad tapeworms (Cestoda: Diphyllobothriidea) are the principal agents of widespread food-borne cestodosis. Diphyllobothriosis and diplogonoporosis, caused by members of the genera Diphyllobothrium, Diplogonoporus and Adenocephalus, are the most common fish cestodoses with an estimated 20million people infected worldwide, and has seen recent (re)emergences in Europe due to the increasing popularity of eating raw or undercooked fish. Sparganosis is a debilitating and potentially lethal disease caused by the larvae of the genus Spirometra, which occurs throughout much of the (sub)tropics and is caused by the consumption of raw snakes and frogs, and drinking water contaminated by infected copepods. Both diseases are caused by several species, but the frequency by which the transition to humans has occurred has never been studied. Using a phylogenetic framework of 30 species based on large and small nuclear ribosomal RNA subunits (ssrDNA, lsrDNA), large subunit mitochondrial ribosomal RNA (rrnL) and cytochrome c oxidase subunit I (cox1), we hypothesize that humans have been acquired asaccidental hosts four times across the tree of life of diphyllobothriideans. However, polytomies prevent an unambiguous reconstruction of the evolution of intermediate and definitive host use. The broad host spectrum and the frequency with which switching between major host groups appears to have occurred, may hold the answer as to why accidental human infection occurred multiple times across the phylogeny of diphyllobothriideans. In this study Diplogonoporus is determined to be the junior synonym of Diphyllobothrium. Furthermore, we divide the latter polyphyletic genus into (i) the resurrected genus Dibothriocephalus to include freshwater and terrestrial species including Dibothriocephalus dendriticus, Dibothriocephalus latus and Dibothriocephalus nihonkaiensis as the most common parasites of humans, and (ii) the genus Diphyllobothrium to accommodate parasites from cetaceans including

Anaplasma/Ehrlichia species are tick-transmitted pathogens that cause infections in humans and numerous domestic and wild animal species. There is no information available on the molecular characteristics and phylogenetic position of Anaplasma/Ehrlichia spp. isolated from tick species from different geographic locations in Iran. The aim of this study was to determine the prevalence, molecular characteristics, and phylogenetic relationship of both Anaplasma spp. and Ehrlichia spp. in tick species isolated from different domestic animals from two different geographical locations of Iran. A total of 930 ticks were collected from 93 cattle, 250 sheep, and 587 goats inhabiting the study areas. The collected ticks were then investigated for the presence of Anaplasma/Ehrlichia spp. using nested PCR based on the 16S rRNA gene, followed by sequencing. Sequence analysis was done based on the data published in the GenBank on Anaplasma/Ehrlichia spp. isolates using bioinformatic tools such as the standard nucleotide BLAST. Genome of Anaplasma or Ehrlichia spp. was detected in 14 ticks collected in Heris, including 5 Dermacentor marginatus, 1 Haemaphysalis erinacei, 3 Hyalomma anatolicum, and 4 Rhipicephalus sanguineus, also in 29 ticks collected in Chabahar, including 14 R. sanguineus, 8 D. marginatus, 3 Hyalomma Anatolicum, and 4 Hyalomma dromedarii. Partial analysis of the 16S rRNA gene sequence of positive samples collected from goats and sheep showed that they were infected with Anaplasma/Ehrlichia spp. that were 94-98% identical to ovine Anaplasma and 91-96% identical to Neoehrlichia and Ehrlichia spp. The various ticks identified in this study suggest the possible emergence of tick-borne diseases in animals and humans in these regions. R. sanguineus and D. marginatus seem to be predominant vectors responsible for anaplasmosis in these regions. Partial sequence analysis of the 16S rRNA gene showed that A. ovis is genetically polymorphic in these regions. Furthermore, an

This paper reports on endoparasite infections diagnosed in 2012 by standard coproscopical techniques and coproantigen Giardia ELISA in 165 dogs used for sheep herding in 36 farms in central Germany. The overall prevalence of dogs with evidence of endoparasite infections was 27.3% (95% CI 20.6-34.7). The most frequently identified faecal forms were those of ascarids (Toxocara, 6.7%; Toxascaris 3.6%), hookworms (5.5%) and taeniid cestodes (4.2%), followed by those of Trichuris whipworms (3.0%), Capillaria aerophila (1.8%), Angiostrongylus and Crenosoma lungworms (1.2% each) and Cystoisospora canis coccidians (0.6%). Molecular identification demonstrated the seven dogs shedding taeniid eggs positive for Taenia (T.) species tapeworms (five, T. hydatigena; one, T. ovis; one Taenia sp.). Screening of the faeces with the coproantigen ELISA revealed Giardia specific antigen in 5.5% of the samples. The majority of the dogs had evidence of single endoparasite infections (22.4%) while evidence for infection with two or three parasites concurrently was found in six (3.6%) and two (1.2%) of the dogs, respectively. Dogs ≤ 1 year (n = 19) were parasitized more frequently (p < 0.05) with overall gastrointestinal parasites (63.2% vs. 20.5%), ascarids (36.8% vs. 6.8%) and Giardia spp. (21.1% vs. 3.4%) than older dogs (n = 146). Dogs which had been wormed within six months of examination tested less frequently positive for gastrointestinal helminths compared to dogs not wormed (11.1% vs. 25.0%; p = 0.0567). In addition, ear swabs taken from 43 sheep dogs in 2012 were examined, and Otodectes cynotis mites were extracted from one dog. Identification of ectoparasites collected by full body search and combing from 113 sheep dogs in the years 2011 to 2013 revealed infestation of fleas and ticks (each up to five specimens per dog) on 13 and 108 dogs, respectively, with nine dogs carrying both fleas and ticks.

Does the mean adequately represent reading performance? Evidence from a cross-linguistic study

Full Text Available Reading models are largely based on the interpretation of average data from normal or impaired readers, mainly drawn from English-speaking individuals. In the present study we evaluated the possible contribution of orthographic consistency in generating individual differences in reading behaviour. We compared the reading performance of young adults speaking English (one of the most irregular orthographies and Italian (a very regular orthography. In the 1st experiment we presented 22 English and 30 Italian readers with 5-letter words using the Rapid Serial Visual Presentation (RSVP paradigm. In a 2nd experiment, we evaluated a new group of 26 English and 32 Italian proficient readers through the RSVP procedure and lists matched in the two languages for both number of phonemes and letters. The results of the two experiments indicate that English participants read at a similar rate but with much greater individual differences than the Italian participants. In a 3rd experiment, we extended these results to a vocal reaction time (vRT task, examining the effect of word frequency. An ex-Gaussian distribution analysis revealed differences between languages in the size of the exponential parameter (tau and in the variance (sigma, but not the mean, of the Gaussian component. Notably, English readers were more variable for both tau and sigma than Italian readers. The pattern of performance in English individuals runs counter to models of performance in timed tasks (Faust et al., 1999; Myerson et al., 2003 which envisage a general relationship between mean performance and variability; indeed, this relationship does not hold in the case of the English participants. The present data highlight the importance of developing reading models that not only capture mean level performance, but also variability across individuals, especially in order to account for cross-linguistic differences in reading behaviour.

A case of Dipylidium caninum infection in a child from the southeastern Poland.

Dipylidium caninum is a common intestinal tapeworm of dogs, cats and foxes. However, it occasionally infects also humans. We present a case of D. caninum infection in a 2-year-old child living in the Subcarpathian province. The infection was asymptomatic in the first months. The symptoms of abdominal pains, sleep disorders, loss of appetite, hyperactivity and occasional slimy stools appeared later. Proglottids on the underwear, in water while bathing and mobile proglottids passed with the stool were also observed. Prior to appropriate diagnosis the child was treated with pyrantelum (Pyrantelum) and albendazolum (Zentel). However, proglottids were found again in the stool after a few days. We examined stool samples and perianal smears collected from the child and his family. The stool samples were tested by coproscopic methods. Direct methods (direct preparation in 0.9% sodium chloride and in Lugol's solution, Kato thick smear) and concentration methods (decantation with distilled water and Faust's zinc sulphate centrifugal flotation) were used. In the stool samples taken from the child, we observed D. caninum proglottids demonstrating lateral genital pores and many packets of eggs containing from one to a few, mostly 3 to 4 eggs. In the direct preparations in 0.9% sodium chloride and in Lugol's solution single packets with D. caninum eggs were detected. In decantation preparations many D. caninum egg packets were observed. It has to be reported that the child's mother was infected with Giardia intestinalis. Dipylidiasis in humans is a rarely encountered infection in Poland and the diagnosis may be difficult. For these reasons we reported clinical case presentation, diagnostics, treatment and epidemiology of D. caninum infection. We have shown that concentration methods such as decantation might be very helpful in the diagnosis of dipylidiasis.

The enigma of capitalism - Beyond human power II and John Gabriel Borkman. Bjørnstjere Bjørnson and Henrik Ibsen as critics of capitalism

Directory of Open Access Journals (Sweden)

Fredrik Engelstad

2015-02-01

Full Text Available The mid-1890s saw the publication of two seminal critiques of capitalism in Norwegian drama: Bjørnstjerne Bjørnson’s Beyond Human Power – Second Play (1895, and Henrik Ibsen’s John Gabriel Borkman (1896. The obvious differences, as well as the similarities of these plays, invite a comparative analysis. Bjørnson’s play is a sociological depiction of class differences and class struggles, expressed in collective action strategies by employers, and a strange mixture of powerlessness and terrorism by the working class.  The main references are work relations and social and political collectivities. Nevertheless, identities and close social relations are a necessary part of social structures as well as dramatic plots. The analysis of Bjørnson’s play focuses on the relationships between individual lives and individual action on the one hand, and the broad social landscape on the other. John Gabriel Borkman is about a stagnated universe, where all of the main characters are trying to revive the past. Borkman is not about work and collectivities, but about financial capital. To Ibsen, financial capital is the ideal environment for research on the ambitions and shortcomings of individuals. Finance in one sense leads to the aggrandizement of individual power; it makes possible the idea that one man can rule the world. At the same time, there is a world of production in the Ibsenesque universe, as there is a world of social identities in Bjørnson. The inspiration for both plays may be found in the developments of capitalism during the latter half of the nineteenth century, but also in their intertextual relationships with Nietzsche and Goethe’s Faust.

Characteristics of dune-paleosol-sequences in Fuerteventura. - What should be questioned? Dominik Faust, TU Dresden, Germany Tobias Willkommen, TU Dresden, Germany Yurena Yanes, CSIC Granada/Cincinatti, Spain/USA David Richter, TU Dresden, Germany Ludwig Zöller, Uni Bayreuth, Germany The northern part of Fuerteventura is characterized by large dune fields. We investigated dune-paleosol-sequences in four pits to establish a robust stratigraphy and to propose a standard section. An interaction of processes like dune formation, soil formation and redeposition of soils and sand are most important to understand the principles of landscape development in the study area. To our mind a process cycle seem to be important: First climbing-dunes are formed by sand of shelf origin. Then soil formation could have taken place. Soil and/or sand were then eroded and deposited at toe slope position. This material in turn is the source of new sand supply and dune formation. The described cycle may be repeated several times and this ping-pong-process holds on. The results are sections composed of dune layers, paleosols and colluvial material interbedded. Fundamental questions still remain unanswered: Is climate change responsable for changes in process combination (e.g. from dune formation to soil formation)? Or are these features due to divergence phenomenon, where different effects/results (dune and soils) may be linked to similar causes (here: climate)? Assuming that different features (soils and dunes) were formed under one climate, increasing soil forming intensity could be mainly a function of decreasing sand supply. This in turn could be caused by reduced sand production (s. ZECH et al. accepted). However geochemical data and mollusc assemblages point to changing environments in space and even climate modifications in time.

Phthalates are widely used chemicals in household products, which severely affect human health. However, there were limited studies emphasized on young adults' exposure to phthalates in dormitories. In this study, seven phthalates were extracted from indoor dust that collected in university dormitories in Harbin, Shenyang, and Baoding, in the north of China. Dust samples were also collected in houses in Harbin for comparison. The total concentrations of phthalates in dormitory dust in Harbin and Shenyang samples were significantly higher than those in Baoding samples. The total geometric mean concentration of phthalates in dormitory dust in Harbin was lower than in house dust. Di-(2-ethylhexyl) phthalate (DEHP) was the most abundant phthalate in both dormitory and house dust. The daily intakes of the total phthalates, carcinogenic risk (CR) of DEHP, hazard index (HI) of di-isobutyl phthalate (DiBP), dibutyl phthalate (DBP), and DEHP were estimated, the median values for all students in dormitories were lower than adults who live in the houses. Monte Carlo simulation was applied to predict the human exposure risk of phthalates. HI of DiBP, DBP, and DEHP was predicted according to the reference doses (RfD) provided by the United States Environmental Protection Agency (U.S.EPA) and the reference doses for anti-androgenicity (RfD AA) developed by Kortenkamp and Faust. The results indicated that the risks of some students had exceeded the limitation, however, the measured results were not exceeded the limitation. Risk quotients (RQ) of DEHP were predicted based on China specific No Significant Risk Level (NSRL) and Maximum Allowable Dose Level (MADL). The predicted results of CR and RQ of DEHP suggested that DEHP could pose a health risk through intake of indoor dust. Copyright © 2016 Elsevier B.V. All rights reserved.

In this study were proposed different protocols for the treatment of mice naturally infected with Giardia muris. Male Swiss mice were divided into seven groups, with five animals each, in a blind, controlled, randomized by drawing lots and once-repeated experiment. Parasite detection and cure control were performed using the Faust method and search by trophozoites in the intestinal mucosa. Clinical parameters (weight, water and feed consumption, elimination of excreta, aspect of the fur and feces) were also evaluated. All animals were treated with metronidazole (M), fenbendazole (F), and probiotics (P), administered intragastrically, during 7 days. M1, FM1, and F1 groups were treated 1×/day; M3, FM3, and PM3 groups 3×/day; and ST (control group) received only water. After the 5th and 7th days of treatment, the animals in FM1/FM3 and PM3/M3 groups presented, respectively, negative results and remained negative in the following 10 days. Animals in F1 group consumed less water (p = 0.00010) compared with FM1/FM3/PM3. The animals in M1 group compared with FM3/M3, F1 compared with M3, and ST compared with FM1/FM3/M3/PM3 consumed a larger amount of feed (p = 0.00001). The animals in F1 group compared with FM3/M1/M3/PM3, FM1 compared with FM3, and ST compared with FM3/M1/M3/PM3 eliminated lower volume of excreta (p = 0.00001). The results show that the association between F and M potentiates the effects, indicating a synergistic action of these two drugs, and FM1 is the best protocol due to early negativity in the animals, lower concentrations of the drugs, lower risk of toxicity and stress, and less alterations in clinical parameters.

Full Text Available Clonorchis sinensis is a carcinogenic human liver fluke. The present study monitored eggs produced by long-term maintained adult worms of C. sinensis to confirm their egg productivity in vitro. The worms from infected rabbits were incubated in vitro in 1× Locke's solution and broth media (RPMI-1640, DMEM and IMDM. Numbers of expelled eggs were counted sequentially and their morphological changes were monitored by microscopy after 1, 30, 60, and 90 days of cultivation. On the 1-3 days of cultivation, the eggs counted maximum 4,756±202 eggs/worm/day in IMDM medium. The number of eggs gradually decreased less than 1,000 at 7-14 days and below 100 at 21days but continued to pass eggs after 56 days in all media. Length of the eggs were reduced about 1 µm at 30 days, and the length/width ratio was maintained around 1.8 at 30 days but decreased to 1.7 at 60 days and 1.5 at 90 days. Faust-Meleney index (FMI decreased as the cultivation duration increased and lowest FMI (5662.9±974.7 observed in IMDM media at day 90 (P = 0.001. Microscopic findings of the eggs recognized the miracidium in most of eggs at 60 days but not in those at 90 days. Instead, the eggs contained dark granules or vacuoles in the deformed shell at 90 days. Scanning electron microscopy revealed partial loss of wrinkles on the deformed egg surface and prominent abopercular knob. Eggs viability decreased as the cultivation progressed and showed significant positive correlation with FMI and length/width ratio. In conclusion, the cultivated worms pass only the eggs which are preformed in their uterus before cultivation. One gravid C. sinensis contains about 37,000 eggs in its uterus and produces about 4,000 eggs every day. The deformed eggs with FMI less than 7,000 and length/width ratio lower than 1.7 are non-viable.

The standard deviation of the final kinetic energy distribution ({sigma}{sub e}) as a function of mass of final fragments (m) from low energy fission of {sup 234}U, measured with the Lohengrin spectrometer by Belhafaf et al., presents a peak around m = 109 and another around m = 122. The authors attribute the first peak to the evaporation of a large number of neutrons around the corresponding mass number, i.e. there is no peak on the standard deviation of the primary kinetic energy distribution ({sigma}{sub E}) as a function of primary fragment mass (A). The second peak is attributed to a real peak on {sigma}{sub E}(A). However, theoretical calculations related to primary distributions made by H.R. Faust and Z. Bao do not suggest any peak on {sigma}{sub E}(A). In order to clarify this apparent controversy, we have made a numerical experiment in which the masses and the kinetic energy of final fragments are calculated, assuming an initial distribution of the kinetic energy without structures on the standard deviation as function of fragment mass. As a result we obtain a pronounced peak on {sigma}{sub e} (m) curve around m = 109, a depletion from m = 121 to m = 129, and an small peak around m = 122, which is not as great as that measured by Belhafaf et al. Our simulation also reproduces the experimental results on the yield of the final mass Y(m), the average number of emitted neutrons as a function of the provisional mass (calculated from the values of the final kinetic energy of the complementary fragments) and the average value of fragment kinetic energy as a function of the final mass. From our results we conclude that there are no peaks on the {sigma}{sub E} (A) curve, and the observed peaks on {sigma}{sub e} (m) are due to the emitted neutron multiplicity and the variation of the average fragment kinetic energy as a function of primary fragment mass.

The standard deviation of the final kinetic energy distribution (σ e ) as a function of mass of final fragments (m) from low energy fission of 234 U, measured with the Lohengrin spectrometer by Belhafaf et al., presents a peak around m = 109 and another around m = 122. The authors attribute the first peak to the evaporation of a large number of neutrons around the corresponding mass number, i.e. there is no peak on the standard deviation of the primary kinetic energy distribution (σ E ) as a function of primary fragment mass (A).

At the end of the seventies and the beginning of the eighties, there appeared a pressing need of experimental results to assess the LMFBR's safety level. Because of the urgency, analytical studies were not systematically undertaken and maximum credible cover gas instantaneous source terms (radionuclides core release fraction) were got directly from crude out-of-pile experiment interpretations. Two types of studies and mock-ups were undertaken depending on the timescale of the phenomena: instantaneous source terms (corresponding to an unlikely energetic core disruptive accident CDA), and delayed ones (tens of minutes to some hours). The experiments performed in this frame are reviewed in this presentation: 1) instantaneous source term: - FAUST experiments: I, Cs, UO2 source terms (FzK, Germany), - FAST experiments : pool depth influence on non volatile source term (USA), - CARAVELLE experiments: nonvolatile source term in SPX1 geometry (CEA, France); 2) delayed source term: - NALA experiments: I, Cs, Sr, UO2 source term (FzK, Germany), - PAVE experiments: I source term (CEA, France), - NACOWA experiments: cover gas aerosols enrichment in I and Cs (FzK, Germany) - other French experiments in COPACABANA and GULLIVER facilities. The volatile fission products release is tightly bound to sodium evaporation and a large part of the fission products is dissolved in the liquid sodium aerosols present in the cover gas. Thus the knowledge of the amount of aerosol release to the cover gas is important for the evaluation of the source term. The maximum credible cover gas instantaneous source terms deduced from the experiments have led to conservative source terms to be taken into account in safety analysis. Nevertheless modelling attempts of the observed (in-pile or out-of-pile) physico-chemical phenomena have been undertaken for extrapolation to the reactor case. The main topics of this theoretical research are as follows: fission products evaporation in the cover gas (Fz

Full Text Available Malaria-enteroparasitic co-infections are known for their endemicity. Although they are prevalent, little is known about their epidemiology and effect on the immune response. This study evaluated the effect of enteroparasite co-infections with malaria caused by Plasmodium vivax in a border area between Brazil and French Guiana. The cross sectional study took place in Oiapoque, a municipality of Amapá, on the Amazon border. Malaria was diagnosed using thick blood smears, haemoglobin dosage by an automated method and coproparasitology by the Hoffman and Faust methods. The anti-PvMSP-119 IgG antibodies in the plasma were evaluated using ELISA and Th1 (IFN-γ, TNF-α and IL-2, and Th2 (IL-4, IL-5 and IL-10 cytokine counts were performed by flow cytometry. The participants were grouped into those that were monoinfected with vivax malaria (M, vivax malaria-enteroparasite co-infected (CI, monoinfected with enteroparasite (E and endemic controls (EC, who were negative for both diseases. 441 individuals were included and grouped according to their infection status: [M 6.9% (30/441], [Cl 26.5% (117/441], [E 32.4% (143/441] and [EC 34.2% (151/441]. Males prevailed among the (M 77% (23/30 and (CI 60% (70/117 groups. There was a difference in haemoglobin levels among the different groups under study for [EC-E], [EC-Cl], [E-M] and [Cl-M], with (p < 0.01. Anaemia was expressed as a percentage between individuals [CI-EC (p < 0.05]. In terms of parasitaemia, there were differences for the groups [CI-M (p < 0.05]. Anti-PvMSP-119 antibodies were detected in 51.2% (226/441 of the population. The level of cytokines evaluation revealed a large variation in TNF-α and IL-10 concentrations in the co-infected group. In this study we did not observe any influence of coinfection on the acquisition of IgG antibodies against PvMSP119, as well as on the profile of the cytokines that characterize the Th1 and Th2 patterns. However, co-infection increased TNF-α and IL-10

In turn, clinically sound psychological literature studies seem to be forced to go into internal exile and are represented by authors such as FRICKE who aren't members of the institutions of academic literature and film studies. FRICKE's book presents an impressing collection of clinically well-based psycho-traumatological readings focussing on literary texts and films of high-art canonical and popular genres—from GOETHE's Faust and Heinrich Leopold WAGNER's drama Die Kindermörderin to contemporary authors such as WILKOMIRSKI, SCHLINK, GRASS, MANKELL, KRISTOF, etc. and even encompasses popular texts such as the Hannibal Lecter trilogy or the films about the Vietnam veteran, Rambo.

to us the strange wonderful things which they have seen in their proper locality, each in its own special element. How I should enjoy once hearing Humboldt talk!". Besides Goethe's admiration for Humboldt, this excerpt reveals his interest in natural sciences, which experienced significant intensification in September 1824 when Goethe established a personal contact with botanist Carl F. P. von Martius. In this young interlocutor, Goethe soon recognized the qualities of a naturalist which, in the novel, were attributed to Humboldt. He then developed a keen interest in and started to keep up with the publications in which Martius elaborated research, observations and experiments carried out throughout the three and a half years in which he travelled across more than ten thousand kilometers of Brazilian territory together with zoologist Spix. Thus, a most fruitful scientific and cultural exchange arose, rooted mainly in the pantheistic conceptions shared by Weimar's old poet and the young botanist. In addition to focusing on some aspects of Martius's expeditions in Brazil, the present essay aims to expose the reception given to them by Goethe and discuss occasional influxes in his literary production. The reelaboration, in 1825, of one of the songs Goethe had written 43 years earlier with the subtitle Brasilianisch is certainly due to this exchange. We also aim to discuss the hypothesis that certain texts and conceptions by Martius have left marks on passages in the second part of Faust.
