    Full Text Available In Brazil, there is increasing interest in the establishment of captive breeding programs for caiman. However, there is a paucity of in-depth studies on the proper care of these reptiles in captivity, particularly regarding optimal food type and frequency of feeding. The purpose of this study was to determine radiographic-anatomical aspects of, and gastrointestinal transit time of Caiman crocodilus crocodilus using contrast radiography. Ten caiman were used in the study, five males and five females, the animals were physically restrained for administration of a radiographic contrast medium, consisting of 10 ml/kg barium sulfate and mineral oil suspension (70%: 30% respectively, via the orogastric tube. Following contrast medium administration, radiographs were taken via dorsoventral projection first at five minutes, then at 6, 24, 30, 48, 54, 72, 80, 96, 104, 120, 130, 144 and 150 hours. This technique allows visualization of contrast medium passage through the GI tract, which enabled determination of gastrointestinal transit time in the spectacled caiman. The average time for contrast medium passage through the digestive tract of this species was 117 ± 29.6 h for females and 86.4 ± 21.5 h for males.

    Spectacled caiman (Caiman crocodilus) are fish-eating crocodilians that inhabit freshwater habitat in tropical regions of the Americas. To assess the exposure of caiman to pesticides from banana plantations, the authors collected whole blood samples (30 mL) from 14 adult caiman that were captured in the North Atlantic region of Costa Rica. Blood samples were analyzed for 70 legacy- and current-use pesticides and breakdown products using newly developed ultra-trace, high-resolution mass spectrometry (HRMS). Caiman accumulated pesticides ranked by concentration as dieldrin > permethrin > mirex > 4,4'-DDE > alpha-endosulfan > heptachlor epoxide > oxychlordane > heptachlor > cypermethrin. Caiman within the high-intensity banana crop watershed of Rio Suerte had higher pesticide burdens relative to other more remote locations (F = 12.79; p = 0.00). Pesticide concentration decreased with distance from upstream banana plantations in this river system (F = 20.76; p = 0.00). Caiman body condition was negatively correlated with total pesticide concentrations (F = 6.23; p = 0.02) and with proximity to banana plantations (F = 5.05; p = 0.04). This suggests that either pesticides elicited toxic effects in caiman, resulting in diminished overall health, or that the quantity or quality of their prey was reduced by pesticides downstream of plantation waterways. The authors' results indicate that pesticide use in banana plantations is impacting a high trophic level species inhabiting one of the most important wilderness areas in Costa Rica (Tortuguero National Park).

    The thalamic reticular nucleus was investigated in one group of crocodilians, Caiman crocodilus. This neuronal aggregate is composed of two parts: a compact portion and a diffuse region made up of scattered cells within the forebrain bundles. In Caiman, both the lateral and medial forebrain bundles project to the telencephalon and the thalamic reticular nucleus is associated with each fiber tract. In the lateral forebrain bundle, the compact area is termed the nucleus of the dorsal peduncle (dorsal peduncular nucleus) while the diffuse part is called the perireticular area. In the medial forebrain bundle, the interstitial nucleus comprises one part of the compact area while another region without a specific neuronal label is also present. Similar to the perireticular cells of the lateral forebrain bundle, scattered cells are also present in the medial forebrain bundle. Morphological features of the thalamic reticular nucleus are revealed with stains for the following: fibers; cells; succinic acid dehydrogenase; and acetylcholinesterase. Regardless of which dorsal thalamic nucleus was injected, a localized region of the thalamic reticular nucleus contained retrogradely labeled cells and anterogradely labeled axons and terminals. This grouping was termed clusters and was felt to represent the densest interconnection between the dorsal thalamus and the reticular nucleus. Using clusters as an index of interconnections, the reticular nucleus was divided into sectors, each of which was associated with a specific dorsal thalamic nucleus. An organization similar to that found in Caiman is present in other sauropsids as well as in mammals. These data suggest that a thalamic reticular nucleus is present in all amniotes and has morphological properties similar to those described in this analysis. Lastly, a hypothesis is presented to explain how the external shape of the reticular nucleus in Caiman might be transformed into the homologous area in a representative bird and

    Mortadellas manufactured using Caiman yacare meat (70%) and pork fat (30%) were reformulated by substituting pork fat with increasing amounts of soybean oil (25%, 50%, and 100%) and evaluated 7, 30, and 60 days post-manufacture. The substitutions resulted in an increase in fat content and in the percentage of polyunsaturated fatty acids (total PUFA; 18:2 n-6 and 18:3 n-3), and a reduction in saturated fatty acids (total SFA; 14:0 and 16:0). These alterations reduced (Poil compared to the original formulation. The levels of TBARS obtained at day 7 were positively correlated (P<0.01) with 18:2 n-6 and 18:3 n-3 (r=0.83 and 0.84, respectively) and negatively correlated with 17:0 and 17:1 (r=-0.91 and -0.89, respectively).

    Full Text Available AbstractFlour prepared via current assay methodologies from the carcasses of the Pantanal alligator (Caiman crocodilus yacare was analyzed for its chemical composition, minerals, fatty acids, and sensorial profile. Carcasses of the Pantanal alligator, originating from the Coocrijapan scientific zoo, Cáceres MT Brazil, were utilized. The carcasses were cooked for 60 minutes in a pressure cooker with water containing 2% salt and 5% chimichurri. The cooked carcasses were then ground and the mass was used for the manufacture of flour via three techniques: non-smoked, hot-smoked, and liquid-smoked. After each technique, the carcasses were dehydrated at 60ºC for 3h and were ground. Alligator flour was then produced. The moisture of liquid-smoked flour (10.97% was higher than that of non-smoked flour (3.78% and hot-smoked flour (4.43%. The flours provided high protein (57.11% - 58.27% and ash (23.45 – 26.42% rates, and were predominantly calcium (6.77% - 7.69%, phosphorus (3.67% - 4.05%, and iron (73.13 – 273.73 ppm/100 mg. Smoked-flour had a better acceptance rate by tasters when compared to non-smoked flour. Results show that flours produced from alligator carcasses had high protein, ash, and mineral rates and a reasonable acceptability by most tasters.

    Full Text Available The Caiman crocodilus yacare is found from northern Argentina to the southern Amazon basin, mainly occurring in Pantanal. Its food consists of fishes and other aquatic vertebrates and invertebrates, such as crabs, winkles, and insects. Its length can reach 3 meters and this species is important because it provides biological control of other animal species, by feeding on weak, old, and ill individuals, unable to escape its attack. A total of 15 alligators were used, young males and females, using histological techniques; injection techniques with Neoprene latex 450 and vinyl acetate; and radiographic techniques to observe particularities of spleen in this species. The organ has a conical shape, being thicker at its cranial end and tapering at its caudal end. Spleen involved the cranial mesenteric artery, which went towards the intestines, from its origin in the celiac artery until its middle third, through the splenic parenchyma in all preparations. Spleen irrigation in the alligator was originated from the celiac artery, through its branch, the cranial mesenteric artery, which branched into splenic arteries, only within this organ. The splenic veins showed up as the cranial, craniomedial, medial, and caudal splenic veins which drain from the splenic capsule to the medullary region, going through the cortical region and going towards the hepatic portal vein. Spleen in the alligator showed no correspondence between the arteries and veins responsible for the vascularization of a certain splenic territory, but one observed arteries irrigating and veins draining particular areas of the splenic parenchyma.

    Full Text Available Tabanid females are better known as hematophagous on man and other mammals, and linked to mechanical transmission of parasites. The association between tabanids and reptiles is poorly known, but has been gaining more corroboration through experiments and occasional observation in the tropics. The present study was conducted at a military base (CIGS/BI-2, situated 54 km from Manaus, Amazonas, in a small stream in a clearing (02°45'33"S; 59°51'03"W. Observations were made monthly, from April 1997 to March 1998, during two consecutive days. At the same time, other vertebrate animals were offered, including humans. However in this paper only data obtained on a common caiman, Caiman crocodilus (Linn., and an anaconda, Eunectes murinus (Linn., in diurnal observations from 05:30 a.m. to 18:30 p.m., will be discussed. A total of 254 tabanid specimens were collected, 40 from the anaconda and 214 from the caiman. Four tabanid species were recorded on these two reptiles: Stenotabanus cretatus Fairchild, S. bequaerti Rafael et al., Phaeotabanus nigriflavus (Kröber and Tabanus occidentalis Linn. Diurnal activities showed species-specific patterns. The first three species occurred only in the dry season. T. occidentalis occurred during the whole observation period, and with increased frequency at the end of the dry season. We observed preferences for body area and related behavior of the host. Observations on the attack of tabanids on one dead caiman are also presented.

During the incubation, three eggs were opened in order to check their viability. 94.11% of hatchability was detected, with the hatching of 16 eggs. The hatched animals were kept under two different temperatures during growth (28ºC and 32°C, and submitted to morphometrical analysis. The collected data were analyzed according to the analysis of variance. The characteristics of the weight of the animals and the width of the head did not present significant differences (P > 0.05 between the treatments. The circumference of the belly and width of snout at nostrils were the ones that had the best (P < 0.05 results at 28°C. The other characteristics as total length, tail length ,snout-vent length ,head length, eye length, snout length, width of snout at mid-point and distance between limbs showed better results at 32°C. It may be concluded that temperature variation did not influence the gain of weight, but the temperature of 32°C was the best for the general development of the animals.

    Full Text Available The legal Pantanal caiman (Caiman crocodilus yacare farming, in Brazil, has been stimulated and among meat preservation techniques the salting process is a relatively simple and low-cost method. The objective of this work was to study the sodium chloride diffusion kinetics in farmed caiman muscle during salting. Limited volumes of brine were employed, with salting essays carried at 3, 4 and 5 brine/muscle ratios, at 15%, 20% and 25% w/w brine concentrations, and brine temperatures of 10, 15 and 20ºC. The analytical solution of second Fick's law considering one-dimensional diffusion through an infinite slab in contact with a well-stirred solution of limited volume was used to calculate effective salt diffusion coefficients and to predict the sodium chloride content in the fillets. A good agreement was obtained between the considered analytical model and experimental data. Salt diffusivities in fillets were found to be in the range of 0.47x10-10 to 9.62x10-10 m²/s.

  2. Unidirectional photoreceptor-to-Muller glia coupling and unique K+ channel expression in Caiman retina.

    Full Text Available BACKGROUND: Müller cells, the principal glial cells of the vertebrate retina, are fundamental for the maintenance and function of neuronal cells. In most vertebrates, including humans, Müller cells abundantly express Kir4.1 inwardly rectifying potassium channels responsible for hyperpolarized membrane potential and for various vital functions such as potassium buffering and glutamate clearance; inter-species differences in Kir4.1 expression were, however, observed. Localization and function of potassium channels in Müller cells from the retina of crocodiles remain, hitherto, unknown. METHODS: We studied retinae of the Spectacled caiman (Caiman crocodilus fuscus, endowed with both diurnal and nocturnal vision, by (i immunohistochemistry, (ii whole-cell voltage-clamp, and (iii fluorescent dye tracing to investigate K+ channel distribution and glia-to-neuron communications. RESULTS: Immunohistochemistry revealed that caiman Müller cells, similarly to other vertebrates, express vimentin, GFAP, S100β, and glutamine synthetase. In contrast, Kir4.1 channel protein was not found in Müller cells but was localized in photoreceptor cells. Instead, 2P-domain TASK-1 channels were expressed in Müller cells. Electrophysiological properties of enzymatically dissociated Müller cells without photoreceptors and isolated Müller cells with adhering photoreceptors were significantly different. This suggests ion coupling between Müller cells and photoreceptors in the caiman retina. Sulforhodamine-B injected into cones permeated to adhering Müller cells thus revealing a uni-directional dye coupling. CONCLUSION: Our data indicate that caiman Müller glial cells are unique among vertebrates studied so far by predominantly expressing TASK-1 rather than Kir4.1 K+ channels and by bi-directional ion and uni-directional dye coupling to photoreceptor cells. This coupling may play an important role in specific glia-neuron signaling pathways and in a new type of K

    The discovery of Trichinella zimbabwensis in farm crocodiles of Zimbabwe has opened up a new frontier in the epidemiology of the Trichinella genus. The objective of the present study was to investigate the infectivity of encapsulated species (T. spiralis, T. nativa, T. britovi, T. murrelli and T. nelsoni) and non-encapsulated species (T. pseudospiralis, T. papuae and T. zimbabwensis) in caimans (Caiman crocodilus), varans (Varanus exanthematicus), pythons (Python molurus bivittatus) and turtles (Pelomedusa subrufa) raised at their natural temperature range (26-32 degrees C). Mice and chickens were used as controls. At 6 days post-infection (p.i.), adult worms were detected in the small intestine of reptiles infected with T. papuae and T. zimbabwensis, of chickens infected with T. pseudospiralis and of mice infected with all encapsulated and non-encapsulated species. At 60 days p.i., T. papuae and T. zimbabwensis adult worms were collected from the intestine of varans and caimans and larvae from muscles of the four reptile species, T. pseudospiralis larvae from muscles of chickens, and larvae of all Trichinella species from mouse muscles. The highest reproductive capacity index of both T. papuae and T. zimbabwensis was observed in varans. The results show that T. papuae and T. zimbabwensis are able to complete their entire life-cycle in both poikilothermic and homoiothermic animals. PMID:15074882

    2011-12-01

    In spite of the importance of crocodilian vocalizations for the understanding of the evolution of sound communication in Archosauria and due to the small number of experimental investigations, information concerning the vocal world of crocodilians is limited. By studying black caimans Melanosuchus niger in their natural habitat, here we supply the experimental evidence that juvenile crocodilians can use a graded sound system in order to elicit adapted behavioral responses from their mother and siblings. By analyzing the acoustic structure of calls emitted in two different situations ('undisturbed context', during which spontaneous calls of juvenile caimans were recorded without perturbing the group, and a simulated 'predator attack', during which calls were recorded while shaking juveniles) and by testing their biological relevance through playback experiments, we reveal the existence of two functionally different types of juvenile calls that produce a different response from the mother and other siblings. Young black caimans can thus modulate the structure of their vocalizations along an acoustic continuum as a function of the emission context. Playback experiments show that both mother and juveniles discriminate between these 'distress' and 'contact' calls. Acoustic communication is thus an important component mediating relationships within family groups in caimans as it is in birds, their archosaurian relatives. Although probably limited, the vocal repertoire of young crocodilians is capable of transmitting the information necessary for allowing siblings and mother to modulate their behavior. PMID:21978842

    Full Text Available This is the first report on the distribution and relative abundance of the broad-snouted caiman on Santa Catarina Island. The study estimated the relative abundance of caiman along the rivers at Estação Ecológica de Carijós, in addition to evaluating the occurrence of this species in the entire area of the Ratones River plain on the northwestern portion of the island. The mean relative abundance obtained by nocturnal counts was 0.25 (±0.07 caiman/km surveyed. There was a weak correlation between the number of caimans and the air temperature. Based on interviews with the local community and nocturnal surveys of caimans in rivers and reservoirs surrounding the protected area, we concluded that the range occupied by caimans covered the entire area of the Ratones river plain, inhabiting natural habitats (rivers, mangroves, swamps as well as artificial habitats (reservoirs and water channels. Although this study provides basic information about the broad-snouted caiman population on this part of the island, it is aimed mainly at providing guidance for future research.

    The expansion and intensification of agriculture during the past 50 years is unprecedented, and thus environmental problems have been triggered at different scales. These transformations have caused the loss of habitat and biodiversity, and disruption of the structure and functioning of ecosystems. As a result of the expansion of the agricultural frontier in the recent past, many areas of the natural geographic distribution of the local wildlife, among them crocodilians and particularly the broad snouted caiman (Caiman latirostris), are being exposed to contaminants. The present study was designed to evaluate the effect of commercially-mixed glyphosate (RU) on some parameters of the immune system of C. latirostris. Two groups of caimans were exposed for two months to different concentrations of RU recommended for its application in the field, while one group was maintained as an unexposed control. The RU concentration was progressively decreased through the exposure period to simulate glyphosate degradation in water. After exposure, total and differential white blood cell (WBC), and complement system activity (CS) were determined. In addition, the animals were injected with a solution of lipopolysaccharide (LPS) from Escherichia coli to trigger an immune response and evaluate the parameters associated with it. The results showed that an effect of the herbicide on CS was observed, as animals exposed to RU showed a lower CS activity than animals from the negative control (NC) but not in total WBC. In the case of leukocyte population counts, differences were only found for heterophils and lymphocytes. PMID:26658029

  11. Roles of Helicobacter pylori BabA in gastroduodenal pathogenesis

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Interactions between BabA and Lewis b (Leb) related antigens are the best characterized adhesin-receptor interactions in Helicobacter pylori (H pylori). Several mechanisms for the regulation of BabA expression are predicted, including at both transcriptional and translational levels. The formation of chimeric proteins (babA/B or babB/A chimeras) seems to play an especially important role in translational regulation. Chimeric BabB/A protein had the potential to bind Leb;however, protein production was subject to phase variation through slipped strand mispairing. The babA gene was cloned initially from strain CCUG17875, which contains a silent babA1 gene and an expressed babA2 gene. The sequence of these two genes differs only by the presence of a 10 bp deletion in the signal peptide sequence of babA1 that eliminates its translational initiation codon. However, the babA1 type deletion was found only in strain CCUG17875. A few studies evaluated BabA status by immunoblot and confirmed that BabA-positive status in Western strains was closely associated with severe clinical outcomes. BabA-positive status also was associated with the presence of other virulence factors (e.g. cagA-positive status and vacA s1 genotype). A small class of strains produced low levels of the BabA protein and lacked Leb binding activity. These were more likely to be associated with increased mucosal inflammation and severe clinical outcomes than BabA-positive strains that exhibited Leb binding activity. The underlying mechanism is unclear, and further studies will be necessary to investigate how the complex BabA-receptor network is functionally coordinated during the interaction of Hpylori with the gastric mucosa.

    Caiman latirostris is a South American crocodilian species characterized as a sentinel of the presence of endocrine-disrupting compounds (EDCs). Evaluating developmental events in hormone-dependent organs, such as the oviduct, is crucial to understand physiological postnatal development, to identify putative periods of exposure sensitive to EDCs, and/or to identify biomarkers useful to evaluate the effects of EDC exposure. In this study, we describe the histomorphological features of C. latirostris oviducts by establishing the ontogeny of changes at cellular, tissue and molecular levels from the neonatal to the pre-pubertal juvenile stages. Since the histological diagnosis of the adenogenic oviduct lies on a group of features, here we defined a histofunctional score system and a cut-off value to distinguish between preadenogenic and adenogenic oviducts. Our results showed that the maturation of the C. latirostris oviduct is completed postnatally and characterized by changes that mimic the pattern of histological modifications described for the mammalian uterus. Ontogenic changes in the oviductal epithelium parallel changes at subepithelial level, and include collagen remodeling and characteristic spatial-temporal patterns of α-actin and desmin. The expression pattern of estrogen receptor alpha and progesterone receptor evidenced that, even at early postnatal developmental stages, the oviduct of C. latirostris is a target organ of endogenous and environmental hormones. Besides, oviductal adenogenesis seems to be an estrogen-dependent process. Results presented here provide not only insights into the histophysiological aspect of caiman female reproductive ducts but also new tools to better characterize caimans as sentinels of endocrine disruption.

    We describe irregularly calcified egg and eggshell morphologies for the first time in nests of the broad-snouted caiman, Caiman latirostris. Research is based on detailed descriptions of 270 eggs from a total sample of 46,800 collected between 2005 and 2011 in Santa Fe Province, Argentina, and encompasses animals from both natural habitats and held in captivity. We discuss possible reasons for the occurrence of eggs with different mineralisation patterns in our extensive C. latirostris field sample and its conservation significance; the chemistry of egg laying in amniotes is sensitive to environmental contamination which, in turn, has biological implications. Based on our egg sample, we identify two caiman eggshell abnormalities: (1) regularly calcified eggs with either calcitic nodules or superficial wrinkles at one egg end and (2) irregularly calcified eggs with structural gaps that weaken the shell. Some recently laid clutches we examined included eggs with most of the shell broken and detached from the flexible membrane. Most type 1 regularly calcified eggs lost their initial calcified nodules during incubation, suggesting that these deposits do not affect embryo survival rates. In contrast, irregularly calcified caiman eggs have a mean hatching success rate of 8.9 % (range 0-38 %) across our sample compared to a mean normal success of 75 %. Most irregularly calcified caiman eggs probably die because of infections caused by fungi and bacteria in the organic nest material, although another possible explanation that merits further investigation could be an increase in permeability, leading to embryo dehydration.

    Classification and influence matrix analysis (CAIMAN) is a new classification method, recently proposed and based on the influence matrix (also called leverage matrix). Depending on the purposes of the classification analysis, CAIMAN can be used in three outlines: (1) D-CAIMAN is a discriminant classification method, (2) M-CAIMAN is a class modelling method allowing a sample to be classified, not classified at all, or assigned to more than one class (confused) and (3) A-CAIMAN deals with the asymmetric case, where only a reference class needs to be modelled. In this work, the geographic classification of samples of wine and olive oil has been carried out by means of CAIMAN and its results compared with discriminant analysis, by focusing great attention on the model predictive capabilities. The geographic characterization has been carried out on three different datasets: extra virgin olive oils produced in a small area, with a "protected denomination of origin" label, wines with different denominations of origin, but produced in enclosed geographical areas, and olive oils belonging to different production areas. Final results seem to indicate that the application of CAIMAN to the geographical origin identification offers several advantages: first, it shows--on an average basis--good performances; second, it is able to deal in a simple way classification problems related to tipicity, authenticity, and uniqueness characterization, which are of increasing interest in food quality issues.

    We surveyed populations of the broad-snouted caiman, Caiman latirostris, throughout the São Francisco River basin, from Três Marias reservoir, State of Minas Gerais, to the river delta, at the boarder of Sergipe and Alagoas states. We registered the occurrence of crocodilians in 61% of all surveyed localities (n = 64), in which the presence of C. latirostris was confirmed in 44% of the surveyed sites. Caimans occurred in both lentic and lotic habitats, although there was a preference for small dams, oxbow lakes and wetlands. Despite the hunting pressure and human impact on natural habitats, our results indicate that the populations of C. latirostris in the São Francisco basin are not fragmented. PMID:21180900

    Full Text Available Thirty heads with the neck segment of Caiman latirostris were used. The animals were provided from a creation center called Mister Caiman, under the authorization of the Brazilian Institute of Environment and Renewable Natural Resources (Ibama. Animals were sacrificed according to the slaughtering routine of the abattoir, and the heads were sectioned at the level of the third cervical vertebra. The arterial system was washed with cold saline solution, with drainage through jugular veins. Subsequently, the system was filled with red colored latex injection. Pieces were than fixed in 20% formaldehyde, for seven days. The brains were removed, with a spinal cord segment, the duramater removed and the arteries dissected. At the level of the hypophysis, the internal carotid artery gave off a rostral branch, and a short caudal branch, continuing, naturally, as the caudal cerebral artery. This artery projected laterodorsalwards and, as it overpassed the optic tract, gave off its I (the first central branch.

    Helicobacter pylori (Hp) infects half the world's population and causes diverse gastric lesions, from gastritis to gastric cancer. Our aim was to evaluate the significance of secretor and Lewis status in infection and in vitro adherence by Hp expressing BabA adhesin. We enrolled 304 Hp-infected individuals from Northern Portugal. Gastric biopsies, blood and saliva were collected. Polymerase chain reaction (PCR) and immunofluorescence were used to detect BabA+ Hp in gastric biopsies. In vitro adherence by a BabA expressing Hp strain to gastric biopsies was performed. Secretor status was identified by Ulex, a lectin that recognizes secretor-dependent glycan structures in saliva and in gastric mucosa, and by Lewis(a/b) antibodies, and indirectly by identification of an inactivating mutation in the FUT2 gene (G428A). BabA status of infecting Hp was associated with CagA and VacAs1 (p < 0.05), intercellular localization of Hp (p < 0.01) and the presence of intestinal metaplasia (p < 0.05) and degenerative alterations (p < 0.005) in the biopsies. BabA was associated (p < 0.05) with Ulex staining of gastric biopsies and, although not significantly, to absence of homozygosity for FUT2 G428A inactivating polymorphism. In vitro Hp adherence was higher in cases wild-type or heterozygous for FUT2 G428A mutation (p < 0.0001), cases staining for Ulex (p < 0.0001) and a(-)b+ and a(-)b(-) secretor phenotypes (p < 0.001). In conclusion, BabA+ Hp infection/adhesion is secretor-dependent and associated with the severity of gastric lesions. PMID:18498114

    Full Text Available Congracilaria babae was first reported as a red alga parasitic on the thallus of Gracilaria salicornia based on Japanese materials. It was circumscribed to have deep spermatangial cavities, coloration similar to its host and the absence of rhizoids. We observed a parasitic red alga with morphological and anatomical features suggestive of C. babae on a Hydropuntia species collected from Sabah, East Malaysia. We addressed the taxonomic affinities of the parasite growing on Hydropuntia sp. based on the DNA sequence of molecular markers from the nuclear, mitochondrial and plastid genomes (nuclear ITS region, mitochondrial cox1 gene and plastid rbcL gene. Phylogenetic analyses based on all genetic markers also implied the monophyly of the parasite from Hydropuntia sp. and C. babae, suggesting their conspecificity. The parasite from Hydropuntia sp. has a DNA signature characteristic to C. babae in having plastid rbcL gene sequence identical to G. salicornia. C. babae is likely to have evolved directly from G. salicornia and subsequently radiated onto a secondary host Hydropuntia sp. We also recommend the transfer of C. babae to the genus Gracilaria and propose a new combination, G. babae, based on the anatomical observations and molecular data.

    Full Text Available Populations of Caiman latirostris are known to occur in Uruguay but their geographic distribution remains uncertain. This work presents anupdate of the species distribution and conservation status in Uruguay. Surveys conducted by the authors confirmed the presence of this species in the previously known distribution range of northwestern Uruguay, where it seems to be widespread and relatively abundant in contrast to earlier reports. We report new localities for C. latirostris, most relevant being those of the Cebollatí and Tacuarí Rivers, and the Pelotas, India Muerta and San Miguel stream basins, which significantly expand its distribution through important wetlands in the eastern part of the country. The overall distribution is coincident with different landscape types, where lagoons, artificial impoundments, livestock waterholes, rivers, streams, creeks and marshes are inhabited by caiman. Illegal non-commercial hunting was detected all over the country.

    Studies of skin wound healing in crocodilians are necessary given the frequent occurrence of cannibalism in intensive farming systems. Air temperature affects tissue recovery because crocodilians are ectothermic. Therefore, the kinetics of skin wound healing in Caiman yacare were examined at temperatures of 33°C and 23°C. Sixteen caiman were selected and divided into two groups of eight maintained at 23°C or 33°C. The studied individuals' scars were photographed after 1, 2, 3, 7, 15 and 30 days of the experimental conditions, and samples were collected for histological processing after 3, 7, 15 and 30 days. Macroscopically, the blood clot (heterophilic granuloma noticeably remained in place covering the wound longer for the caiman kept at 23°C. Microscopically, the temperature of 23°C slowed epidermal migration and skin repair. Comparatively, new blood vessels, labeled using von Willebrand factor (vWF antibody staining, were more frequently found in the scars of the 33°C group. The collagen fibers in the dermis were denser in the 33°C treatment. Considering the delayed healing at 23°C, producers are recommended to keep wounded animals at 33°C, especially when tanks are cold, to enable rapid wound closure and better repair of collagen fibers because such lesions tend to compromise the use of their skin as leather.

    Full Text Available The aim of this study is to estimate the recreational value of Baba Aman Natural Park near Bojnord in Northeast Iran. The recreational value of Baba Aman Park has been analyzed using a contingent valuation method. For this purpose, 201 on-site questionnaires were administered between June and September of 2006. Visitor’s willingness to pay (WTP for Baba Aman recreational park has been estimated for future entrance fees associated with two scenarios including current conditions and proposed improvements of the recreational services in the park. Average WTP was estimated 1.5 and 2 times more than the current entrance fee, considering two scenarios. These amounts are insignificant when compared to the cost of improving the recreational services of the area. However, found that only 25% of visitors are willing to pay more money beyond the current entrance fee. Statistical analysis has revealed that the monthly income and level of education have significant effects on WTP amounts. Implications are discussed and conclusion drawn.

    AIM: To investigate the prevalence of vacuolating cytotoxin ( vacA), cytotoxin associated gene A ( cagA) and blood adhesion binding antigen ( babA2) genotypes of Helicobacter pylori ( H pylori) isolates from Cuban dyspeptic patients. METHODS: DNA was extracted from H pylori-positive cultures taken from 130 dyspeptic patients. Genotyping was performed by PCR, using specific primers for vacA ( s1, s2, m1, m2), cagA and babA2 genes. Endoscopic observations and histological examinations were used to determine patient pathologies. RESULTS: vacA alleles s1, s2, m1 and m2 were detected in 96 (73.8%), 34 (26.2%), 75 (57.7%) and 52 isolates (40%), respectively, while the cagA gene was detected in 95 isolates (73.2%). One hundred and seven isolates (82.3%) were babA2-positive. A significant correlation was observed between vacAs1m1 and cagA and between vacAs1m1 and babA2 genotypes ( P < 0.001 and P < 0.05, respectively) and between babA2 genotype and cagA status ( P < 0.05); but, no correlation was observed between vacAs1 and babA2 genotypes. Eighty five (65.4%) and 73 (56.2%) strains were type 1 ( vacAs1- cagA-positive) and "triplepositive" ( vacAs1- cagA- babA2-positive), respectively, and their presence was significantly associated with duodenal ulcer ( P < 0.01 and P < 0.001, respectively). CONCLUSION: The distribution of the main virulence factors in the Cuban strains in this study resembled that of the Western-type strains, and the more virulent H pylori isolates were significantly associated with duodenal ulcer, ulcer disease being the worst pathology observed in the group studied.

    production chain of wild populations. In Brazil, there are no protocols for this type of meat. The slaughter and processing were performed using a simplified, traditional floating raft system and a water treatment system that used both filtration and chemicals. The animals were caught using a hook, harpoon, resting pole, and cable snare. The wild caimans of two species (Melanosuchus niger and Caiman crocodilus were captured in the region of the Piagaçu-Purus Sustainable Development Reserve in Central Amazon during three harvesting events. After each event, we progressively improved the meat-processing protocol. Microbiological testing of the meat was performed as described in norms and Brazilian legislation for fish meat. As a result, we achieved improvements in the sanitary quality of the meat of the killed animals for 57%, 76.5% and 100% of the samples obtained during the first, second, and third harvesting events, respectively. There were significant differences in the microbiological quality of the meat, with a reduction in the disapproval of the samples. The process of capturing animals, the cable snare, and the restraining pole were the factors that least affected the quality of the meat; in addition, animals between 81 and 100 cm of CRC had a lower risk of microbiological contamination. We can conclude that health surveillance activities, such as hand hygiene when handling meat, improvements in water quality, selection of animals of the most appropriate size for slaughter, and capture by less invasive methods can reduce the potential for microbiological contamination of the meat contribute to decrease the potential for microbiological contamination of meat.

    Protaeolidiella atra Baba, 1955 and Pleurolidia juliae Burn, 1966 are two species traditionally regarded as the members of Aeolidiidae but recently attributed to Facelinidae. Because of their apparent similarities, Rudman (J Molluscan Stud 56:505-514, 1990) rendered P. juliae as a junior synonym of P. atra. In this paper, we conducted a review of both species and completed their descriptions with new data regarding the anatomy of the reproductive system . P. atra and P. juliae have differences in their colouration, number of cerata and characteristics of their reproductive system. Based on these differences, we conclude that these species are not conspecific and should be regarded as distinct taxa.

    This study examined the population structure, reproductive cycle and feeding pattern of the lanternfish Lampanyctus crocodilus in the Balearic Basin (north-west Mediterranean Sea) from a depth of 450 to 1800 m and at a seasonal scale. Juveniles were mainly located at shallower depths, but also at deepest stations in autumn, while adults mostly inhabited intermediate depths with their centre of population density (CPD) located at 800-1000 m of depth. The migration of adults to deeper depths was detected in late summer to autumn, probably linked to the occurrence of nepheloid layers at c. 1200 m, which in turn enhances the biomass of the zooplankton prey. The diet was mainly based on euphausiids and mysids, with marked seasonal variations both on the upper (450-800 m) and lower (1000-1800 m), where suprabenthic gammariids and pelagic decapods were also dominant. Stomach fullness increased from winter to autumn on the US, while it had a maximum in spring on the LS, in parallel with high consumption of gelatinous zooplankton, which is probably more available after the phytoplankton bloom in late winter. Reproduction occurred in winter, confirmed by the higher percentage of mature females and high gonadosomatic indices (I(G)) at both depth ranges. Hepatosomatic indices (I(H)) showed an inverse trend to I(G) on the US, except in autumn, and was almost parallel on the LS, probably attributable to the migration of adults, which determined different temporal schemes in energy use and storage for reproduction on the US v. LS. Consistent with the different patterns observed at the two depth ranges, environmental drivers of fullness (i.e. feeding intensity) and I(G) (as a proxy of reproductive cycle) differed on the US and LS. The biomass of mysids and euphausiids was the greatest explanatory variables of fullness on the US and LS, pointing to the increasing feeding intensity when a resource was more available. I(H) also explained fullness, suggesting that greater

    Our objective was to examine the physico-chemical and sensory attributes of low-sodium restructured caiman steaks containing microbial transglutaminase (MTG) and salt replacers (KCl and MgCl2). Trimmings from caiman carcasses were processed into restructured steaks with or without MTG and salt replacers; the five treatments were CON (1.5% NaCl), T-1 (1.5% NaCl+1% MTG), T-2 (0.75% NaCl+1% MTG+0.75% KCl), T-3 (0.75% NaCl+1% MTG+0.75% MgCl2), and T-4 (0.75% NaCl+1% MTG+0.375% KCl+0.375% MgCl2). T-4 demonstrated the greatest (P0.05) to controls in salty flavor. Our findings suggest that the combination of MTG, KCl, and MgCl2 can be employed as a suitable salt reduction strategy in restructured caiman steaks without compromising sensory attributes and consumer acceptance.

    The study of the cephalic shape of crocodilian is relevant in the fields of ecology, systematics, evolution, and conservation. Therefore, the integration of geometric analysis within quantitative genetics allows the evaluation of the inheritable shape components. In this study, the dorsal cephalic region of 210 Caiman latirostris hatchlings was analyzed from seven populations in Santa Fe, Argentina, to detect intra-, and inter-population phenotypic variability, and to determine the heritability of biological shape and size, using newly available geometric morphometric tools. The principal component analysis showed two configurations of cephalic shape that could be related to sexual dimorphism. In the canonical variate analysis, Procrustes distances between groups indicated that there are differences in shape among populations. Furthermore, the method of partial least squares indicated a covariation between cephalic shape and environmental variables. Regarding to CS of the skull we found significant differences among populations, moreover the partial least squares was also significant. Estimates of the heritability of shape and size were high, indicating that the components of these features are susceptible to the selection. PMID:26682625

In the rare televised appearances outside of Slavic nations, Baba Yaga tends to show up in MOTW episodes. While some MOTW are contemporary inventions, many, like Baba Yaga, are mythological and fantastic creatures from folk narratives. Employing the concept of the folkloresque, we explore how contemporary audiovisual tropes gain integrity and traction by indexing traditional knowledge and belief systems. In the process, we examine key affordances of these forms involving the possibilities of wonder and the portability of tradition. Using digital humanities methods, we built a “monster typology” by scraping lists of folk creatures, mythological beasts, and other supernatural beings from online information sources, and we used topic modeling to investigate central concerns of MOTW series. Our findings indicate connections in these shows between crime, violence, family, and loss. The trope formulates wonder and families through folk narrative and monster forms and functions. We recognize Baba Yaga’s role as villain in these episodes and acknowledge that these series also shift between episodic and serial narrative arcs involving close relationships between characters and among viewers and fans.

    Exposure to environmental contaminants known as endocrine disruptors (EDs) alters the development and function of reproductive organs in several species. Bisphenol A (BPA) is an estrogenic chemical that leaches from dental materials and plastic food and beverage containers. BPA has been found in sewage, surface and drinking water, and therefore poses a potentially significant risk for human and wildlife. Prenatal exposure of rodents to environmentally relevant doses of BPA alters the development of the reproductive organs of male and female offspring. Species with temperature dependent sex determination (TSD) could act as sentinels of ecosystem health by providing sensitive biomarkers of endocrine disruptor's effects. We selected Caiman latirostris as an animal model to study endocrine disruption caused by BPA. The aim of this study was to determine whether exposure in ovum to BPA could cause estrogen-like effects on the reproductive system of C. latirostris. Sex determination and gonadal histoarchitecture were the endpoints evaluated after in ovum exposure to different doses of BPA and 17beta-estradiol (E(2)). We confirmed that C. latirostris is a species with TSD and additionally demonstrated that BPA causes estrogen-like developmental effects by reversing gonadal sex and altering gonadal histoarchitecture. Differences in responses to BPA and E(2) in our in vivo system were on the order of 100-fold. In contrast published in vitro studies have reported differences on the order of 10,000x or more. These results support the utility of C. latirostris, a species in which sex determination is temperature dependent, as a tool in assessing estrogenic activity in vivo and as a sentinel to monitor EDs in aquatic environment.

    Helicobacter pylori is a human pathogen that colonizes about 50% of the world's population, causing chronic gastritis, duodenal ulcers and even gastric cancer. A steady emergence of multiple antibiotic resistant strains poses an important public health threat and there is an urgent requirement for alternative therapeutics. The blood group antigen-binding adhesin BabA mediates the intimate attachment to the host mucosa and forms a major candidate for novel vaccine and drug development. Here, the recombinant expression and crystallization of a soluble BabA truncation (BabA(25-460)) corresponding to the predicted extracellular adhesin domain of the protein are reported. X-ray diffraction data for nanobody-stabilized BabA(25-460) were collected to 2.25 Å resolution from a crystal that belonged to space group P21, with unit-cell parameters a = 50.96, b = 131.41, c = 123.40 Å, α = 90.0, β = 94.8, γ = 90.0°, and which was predicted to contain two BabA(25-460)-nanobody complexes per asymmetric unit.

    Full Text Available En este artículo se analiza el cuento "Las babas del diablo" de Julio Cortázar desde una perspectiva visual. La hipótesis central de este texto es que Cortázar relaciona escritura, fotografía y cine para poner enjuego la relación entre arte, sujeto y realidad. Esta conexión está mediada por la técnica, específicamente por aparatos como la cámara fotográfica y la máquina de escribir. Cortázar vincula fotografía y escritura a partir del concepto de traducción, construyendo un protagonista que es al mismo tiempo un observador y un letrado. Este protagonista pasa de ser un sujeto eminentemente fotográfico, a convertirse en el involuntario espectador de un filme.In this article, I analyze the short story "Blow-up " by Julio Cortázar from a visual point of view. This text's central hypothesis is that Cortázar relates writing, photography and cinema in order to put into play the connection between art, subject and reality. This link is mediated by technique, specifically by apparatuses such as the photographic camera and the typewriter. Cortázar associates photography and writing through the concept of translation, constructing a protagonist that is at the same time an observer and a letrado. This protagonist, first a photographic subject, becomes an involuntary film spectator.

    Full Text Available The paper highlights a case study of a rural girls college located in a remote village of Gurdaspur district in Indian Punjab. The idea of this unique college was conceptualised by one Baba Aya Singh, a social and religious activist, from a village near the college way back in 1925. It was really a revolutionary idea because female education in India, particularly higher education, was a distant dream at that time. The college was, however, started with only 14 rural girls after about half-a-century when the great visionary Baba Aya Singh had a dream to educate the rural girls. Access to and affordability of higher education is the uniqueness of this college. The student has to pay only Rs. 5800 (about US $ 65 per annum, which includes both the tuition fee and boarding and lodging. It is equally significant to note that the entire expenses of the college are met by this and the produce of agricultural land of the college. The college does not take any outside help. The meritorious senior class students teach the junior class students. The college in its own humble, but significant, way made a revolutionary contribution to the education of poor rural girls who, otherwise, would not have dreamt of college education. Apart from, class-room teaching and bookish knowledge, the students are taught social, ethical and management skills in a most natural manner. The product of the college has proved to be the agents of change and rural transformation.

    Full Text Available Después de transcurridos más de 10 años desde la primera Lista Roja de la herpetofauna dela República Argentina realizada por la Asociación Herpetológica Argentina en el año 2000, se re-categorizaron las dos especies de caimanes presentes en el país (Caiman latirostris y C. yacare incorporando nueva información biológica, biogeográfica y ecológica y, correcciones metodológicas. Como resultado, ambas especies fueron categorizadas como No Amenazadas, en base a información actualizada sobre sus áreas de distribución y su abundancia. Los criterios aplicados para el desarrollo de los programas de manejo de ambas especies en Argentina han permitido ampliar el conocimiento de las mismas en una gran diversidad de aspectos. El aprovechamiento sostenible de los yacarés mediante la metodología de cría en granjas o "rancheo" ha demostrado ser de bajo impacto para las poblaciones silvestres y ha revalorizado los humedales que estos reptiles habitan. After more than a decade from the first Red List of the Herpetofauna of Argentina assessed in 2000, we reclassified the two species of argentine caimans, starting from actual information about their biology, biogeography and ecology and including methodological adjustments. As a result, both species Caiman latirostris and C. yacare were included in the Not Endangered category, based on new records about their geographic distribution and populations densities. The criteria applied to the development of management programs of crocodilians in Argentina has improved the knowledge of both species and made a great and wide contribution to several aspects of their biology. The sustainable use of both species of crocodilians has proved to have a minimum impact on wild populations and has put a new value on the wetlands inhabited by this reptiles.

    To survive in adverse conditions, plants have evolved complex mechanisms that “prime” their defense system to respond and adapt to stresses. Their competence to respond to such stresses fundamentally depends on its capacity to modulate the transcriptome rapidly and specifically. Thus, chromatin dynamics is a mechanism linked to transcriptional regulation and enhanced defense in plants. For example, in Arabidopsis, priming of the SA-dependent defense pathway is linked to histone lysine methylation. Such modifications could create a memory of the primary infection that is associated with an amplified gene response upon exposure to a second stress-stimulus. In addition, the priming status of a plant for induced resistance can be inherited to its offspring. However, analyses on the molecular mechanisms of generational and transgenerational priming in the common bean (Phaseolus vulagris L.), an economically important crop, are absent. Here, we provide evidence that resistance to P. syringae pv. phaseolicola infection was induced in the common bean with the synthetic priming activators BABA and INA. Resistance was assessed by evaluating symptom appearance, pathogen accumulation, changes in gene expression of defense genes, as well as changes in the H3K4me3 and H3K36me3 marks at the promoter-exon regions of defense-associated genes. We conclude that defense priming in the common bean occurred in response to BABA and INA and that these synthetic activators primed distinct genes for enhanced disease resistance. We hope that an understanding of the molecular changes leading to defense priming and pathogen resistance will provide valuable knowledge for producing disease-resistant crop varieties by exposing parental plants to priming activators, as well as to the development of novel plant protection chemicals that stimulate the plant's inherent disease resistance mechanisms.

    Caiman yacare (lagarto) and Melanosuchus niger (black caiman), sympatric species in the Bolivian Amazon basin, have been severely overexploited in the past. We present the results of a standardized survey of C. yacare and M. niger populations in order to evaluate their actual population status in twelve oxbow lakes of the Ichilo River floodplain. Additionally we explored the effect of environmental and anthropogenic variables on caiman distribution patterns. The average density of C yacare and M niger in the shoreline of floodplain lakes was of 6 and 1 ind/km, respectively. For both species, the population was composed mainly of juvenile individuals. We used regression tree analysis (RTA) to assess patterns of M. niger and C. yacare densities with eight environmental and two anthropogenic variables. The RTA analysis showed that the variation in the densities of both C. yacare (52.4%) and M. niger (36.8 %) was related to water conductivity. For C yacare, higher densities occurred at higher values of water conductivity, while M. niger densities followed an opposite trend, resulting in relatively well spatially segregated populations of the two species. After excluding conductivity, Lake-River Distance (LRD) was shown to be the main splitting variable in the RTA analysis. The observed distribution patterns may be the result of the historical post-hunting situation, in combination with differences in habitat selection by the two species, and competitive exclusion processes between the two species. M. niger, a species reported to be recovering slowly from previous low population levels, appears relatively well protected in the Ichilo river floodplain. PMID:19256453

    Helicobacter pylori-specific genotypes have been strongly associated with an increased risk of gastric cancer (GC). The aim of the present work was to study the associations of H. pylori virulence factors, vacA i region polymorphisms and babA2 status with GC risk in Azerbaijan patients. The DNA extracted from gastric biopsy specimens was used to access the babA2 and vacA genotypes. Overall, babA2 was present in 85.39 % (76/89) of H. pylori strains: 19 out of 24 (79.16 %) strains from GC, 16 out of 17 (94.14 %) strains from peptic ulcer disease (PUD) and 41 out of 48 (85.14 %) strains from chronic gastritis. No significant association was found between babA2 genotype and clinical outcomes (P > 0.05). i1 vacA polymorphism was detected in 46/89 (51.68 %) strains: in 21/24 (87.5 %), 6/17 (35.29 %) and 19/48 (39.58 %) patients with GC, PUD and chronic gastritis, respectively. i2 allele was detected in 43 (48.31 %) out of all 89 strains examined: 3 (14.28 %) of 24 strains from GC, 11 (64.71 %) of 17 from PUD, and 29 (60.42 %) of 48 strains from chronic gastritis. In this study, multiple linear regression analysis confirmed the strong association of i1 allele with GC (partial regression correlation 0.455 ± 0.101; P = 0). Results of multiple logistic regression analysis showed that vacA i1 genotype was significantly associated with GC compared with a control group (gastritis) (odds ratio 13.142, 95 % CI 3.116-55.430; P = 0). Findings from the measurement of H. pylori babA2 and vacA genotypes indicate a strong correlation between the vacA i1 allele and GC risk in the Azerbaijan area of Iran.

    Full Text Available The Baba Ali skarn deposit, situated 39 km to the northwest of Hamadan (Iran, is the result of a syenitic pluton that intruded and metamorphosed the diorite host rock. Rare earth element (REE values in the quartz syenite and diorite range between 35.4 and 560 ppm. Although the distribution pattern of REEs is more and less flat and smooth, light REEs (LREEs in general show higher concentrations than heavy REEs (HREEs in different lithounits. The skarn zone reveals the highest REE-enriched pattern, while the ore zone shows the maximum depletion pattern. A comparison of the concentration variations of LREEs (La–Nd, middle REEs (MREEs; Sm–Ho and HREEs (Er–Lu of the ore zone samples to the other zones elucidates two important points for the distribution of REEs: 1 the distribution patterns of LREEs and MREEs show a distinct depletion in the ore zone while representing a great enrichment in the skarn facies neighbouring the ore body border and decreasing towards the altered diorite host rock; 2 HREEs show the same pattern, but in the exoskarn do not reveal any distinct increase as observed for LREEs and MREEs. The ratio of La/Y in the Baba Ali skarn ranges from 0.37 to 2.89. The ore zone has the highest La/Y ratio. In this regard the skarn zones exhibit two distinctive portions: 1 one that has La/Y >1 beingadjacent to the ore body and; 2 another one with La/Y < 1 neighbouring altered diorite. Accordingly, the Baba Ali profile, from the quartz syenite to the middle part of the exoskarn, demonstrates chiefly alkaline conditions of formation, with a gradual change to acidic towards the altered diorite host rocks. Utilising three parameters, Ce/Ce*, Eu/Eu* and (Pr/Ybn, in different minerals implies that the hydrothermal fluids responsible for epidote and garnet were mostly of magmatic origin and for magnetite, actinolite and phlogopite these were of magmatic origin with low REE concentration or meteoric water involved.

A comparison of the concentration variations of LREEs (La-Nd), middle REEs (MREEs; Sm-Ho) and HREEs (Er-Lu) of the ore zone samples to the other zones elucidates two important points for the distribution of REEs: 1) the distribution patterns of LREEs and MREEs show a distinct depletion in the ore zone while representing a great enrichment in the skarn facies neighbouring the ore body border and decreasing towards the altered diorite host rock; 2) HREEs show the same pattern, but in the exoskarn do not reveal any distinct increase as observed for LREEs and MREEs. The ratio of La/Y in the Baba Ali skarn ranges from 0.37 to 2.89. The ore zone has the highest La/Y ratio. In this regard the skarn zones exhibit two distinctive portions: 1) one that has La/Y >1 beingadjacent to the ore body and; 2) another one with La/Y < 1 neighbouring altered diorite. Accordingly, the Baba Ali profile, from the quartz syenite to the middle part of the exoskarn, demonstrates chiefly alkaline conditions of formation, with a gradual change to acidic towards the altered diorite host rocks. Utilising three parameters, Ce/Ce*, Eu/Eu* and (Pr/Yb)n, in different minerals implies that the hydrothermal fluids responsible for epidote and garnet were mostly of magmatic origin and for magnetite, actinolite and phlogopite these were of magmatic origin with low REE concentration or meteoric water involved.

    Full Text Available This article begins by examining the concept Sai Baba groups have on the mind, and then argue that their ritual performances are “technologies of the self”, in Foucauldian terms, designed to quiet the mind and gain subjective attitude consisting “let things happen”. Subsequently, we explained that devotees strive to apply this attitude a everyday life give that “mundane” is considered an illusory product of the mind that distracts from the spiritual path. At this point try the classic Weberian theme of “attitude to the world” and how it manifests between Sai groups, especially in regard to the detachment and asceticism. Finally, we conclude that the ritual performances and detachment from worldly are the facets sacred and profane, respectively, of an overall strategy to “kill” the mind set on playing for the Sai devotees.

    Because gastric infection by Helicobacter pylori takes place via the oral route, possible interactions of this bacterium with human salivary proteins could occur. By using modified 1- and 2-D bacterial overlay, binding of H. pylori adhesins BabA and SabA to the whole range of salivary proteins was explored. Bound salivary receptor molecules were identified by MALDI-MS and by comparison to previously established proteome maps of whole and glandular salivas. By use of adhesin-deficient mutants, binding of H. pylori to MUC7 and gp-340 could be linked to the SabA and BabA adhesins, respectively, whereas binding to MUC5B was associated with both adhesins. Binding of H. pylori to the proline-rich glycoprotein was newly detected and assigned to BabA adhesin whereas the SabA adhesin was found to mediate binding to newly detected receptor molecules, including carbonic anhydrase VI, secretory component, heavy chain of secretory IgA1, parotid secretory protein and zinc-alpha(2)-glycoprotein. Some of these salivary glycoproteins are known to act as scavenger molecules or are involved in innate immunity whereas others might come to modify the pathogenetic properties of this organism. In general, this 2-D bacterial overlay technique represents a useful supplement in adhesion studies of bacteria with complex protein mixtures. PMID:19253298

    Babaçu (A. speciosa), Buriti (M. flexuosa), and Macaúba (A. aculeata) are palm trees typical of the ecotone area between Cerrado and the Amazon rainforest. The purpose of this study was to evaluate the antimicrobial potential of the extracts prepared from the leaves of those palms as well as determine their chemical compositions. The ethanol extracts were prepared in a Soxhlet apparatus and tested by disk diffusion and agar dilution technique against Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, and Candida parapsilosis. However, there was no significant activity at concentrations of 25, 50, and 100 mg·Ml−1. Moreover, the phytochemical analysis revealed the presence of tannins, flavonoids, catechins, steroids, triterpenes, and saponins. Gas chromatography (GC/MS) analysis also identified organic acids, such as capric (decanoic) acid, lauric (dodecanoic) acid, myristic (tetradecanoic) acid, phthalic (1,2-benzenedicarboxylic) acid, palmitic (hexadecanoic) acid, stearic (octadecanoic) acid, linoleic (9,12-octadecadienoic) acid (omega-6), linolenic (octadecatrienoic) acid (omega-3), and the terpenes citronellol and phytol. Based on the chemical composition in the palm leaf extracts, the palms have the potential to be useful in the food, cosmetic, and pharmaceutical industries. PMID:27529077

Embora os crocodilianos constituam um importante grupo representante dos Archosauria, nossos conhecimentos acerca de seu desenvolvimento e homologias ainda são escassos. Aqui descrevemos uma sequência detalhada de ossificação dos ossos do crânio de Caiman yacare (Daudin, 1802, objetivando contribuir com informações de foco anatômico. Coletaram-se ao acaso embriões em intervalos regulares durante todo o período de incubação, sendo estes posteriormente submetidos a protocolo de diafanização e coloração de ossos. O padrão de ossificação em C. yacare segue parâmetros gerais em répteis e outros tetrápodes. Os primeiros centros de ossificação correspondem aos ossos dérmicos, envolvidos com funções primárias como a alimentação e respiração (e.g. maxila, dentário, esplenial, angular, pterigoide, ectopterigoide e jugal, incluindo ainda os dentes. Os ossos da porção dorsal do neurocrânio se ossificam posteriormente, evidenciando uma fontanela cranial que permanece até o momento da eclosão.

    Full Text Available There is not enough information about Zarîfî Omar Baba in the sources we have studied. According to the available sources Zarîfî Omar Baba, who was from Ruscuk village within the borders of Bulgaria today, participated in Sa’diyye Sect and he ascended to the position of sheikh in this sect. Zarîfî has two works which are mentioned in the biograhical antologies. These are Pend-name and Divan. Yet, in the catalogue searches we have done 7 more works, which are denoted to belong to him, have been identified. These works are: Tasavvuf-nâme, İsm-i A’zam, Kitâb-ı İ'tikâd, Hikâye-yi Kan Kalesi, Beyân-ı Ser-encâm, Kısasu’l-Enbiyâ and Istılahât-ı Mashayikh. As far as we could study, Zarîfî’s works have religion-sufism and moral contents. His work, Istılahât-ı Mashayikh, which has not been mentioned in the sources, is a kind of dictionary of sufism terms. In this work, which starts with 23 verses narrating some religion and sufism themes, 70 sufism terms are explained in all. It is possible to group these terms into two as names and positions. In this work, names and their characteristics are written in prose while positions are written in verse. Firstly in verse, the author explains the name which identifies the qualities and characterisitcs of human being in his own sufistic point. Then in prose, he explains the positions the one, who has the characteristics of this name, will get to. In this article Zarîfî’s life, his literary personality and works; language, style and contents of Istılahât-ı Mashayikh have been examined. Besides, some terms in this work have been compared to other sufism dictionaries in order to clarify that meanings ascribed to the same terms show difference according to sects, tariqah and perhaps according to time and place. Finally, the text of Istılahât-ı Mashayikh has been translated into contemporary letters in accordance with its two copies by critical edition method.

Parece evidente a relação entre o tipo de atividade profissional e o desenvolvimento da infecção.During a survey of 30 patients with chromoblastomycosis followed at the Hospital dos Servidores do Estado do Maranhão, the authors observed in 2 (6.6%patients with lesions on the buttock. This is an uncommon site for the initial lesions of chromoblastomycosis. There is often a history of microtraumatism during the farming job hence the more frequent development of lesions in the lower limbs. Both patients had 10 years disease, with the presence of nodules and vegetant warty lesions in coalescentplaques on the right buttock. Etiologic diagnosis made through histopatologic and culture exams, with Fonsecaea pedrosoi isolated, the epidemiological exposure of the patients, was suggested by the fact that both worked as babaçu coconut cutters a common activity in Maranhão State. The relation betweenthis kind of professional activity and the development of infection merits for the investigation.

    Full Text Available Este artigo analisa experiências protagonizadas por comunidades cujos modos de vida geram e se sustentam em conhecimentos tradicionais em face de tentativas de implementação de um regime global de propriedade intelectual. Estudos de caso sobre quebradeiras de coco babaçu, no estado do Maranhão, e produtores de queijo serrano, no Estado do Rio Grande do Sul, revelam significados da tradição implícita no conhecimento que se pretende proteger. Dados empíricos, analisados jurídica e antropologicamente, evidenciam, apesar de aparente progresso na legislação, ameaças a múltiplas dimensões de modos de vida fundados em territórios tradicionais. Argumenta-se que, sem a imediata e integral aplicação da Convenção OIT 169, invertem-se os efeitos da incorporação de convenções internacionais no ordenamento jurídico nacional, a exemplo da Convenção da Diversidade Biológica. Conclui-se que as comunidades tradicionais resistem à ilegal apropriação de seus conhecimentos, enquanto setores privados neles interessados utilizam-se do estado de direito para legalizar sua pilhagem.

    Despite the clinical importance of Helicobacter pylori in human gastric disorders, its exact route of transmission is still uncertain. Based on the contentious hypothesis and findings of previous investigations, water may play an important role in the transmission of H. pylori to humans. This study was carried out to investigate the vacA, cagA, oipA, iceA and babA2 genotype status and antimicrobial resistance properties of H. pylori strains isolated from the drinking water samples of four major provinces in Iran. A total of 400 drinking water samples were cultured and tested. H. pylori-positive strains were analyzed for the presence of various genotypes and antimicrobial resistance. Twelve of 400 (3%) water samples were positive for H. pylori. Samples from Isfahan province had the highest, while those from Shiraz had the lowest prevalence of H. pylori. The seasonal distribution was also determined, with the highest prevalence of bacteria in the summer season (7.36%). H. pylori strains harbored the highest levels of resistance against ampicillin (100%), erythromycin (75%), clarithromycin (75%), and trimethoprim (58.3%). The most commonly detected genotypes were vacAs1a (83.3%), vacAm1a (66.6%), vacAs2 (50%) and cagA (50%). The presence of similar genotypes in the H. pylori strains of drinking water and those of human clinical samples suggest that contaminated water maybe the sources of bacteria. Spiramycin and furazolidone are suggested for the treatment of cases of H. pylori infection.

    方北方的《娘惹与峇峇》通过叙述马来西亚父、子、孙三代华人家庭从鼎盛走向衰落的过程,控诉了殖民主义文化对马来西亚华人的思想、文化所造成的严重毒害。在殖民文化影响下,以娘惹为代表的华族社会内部形成了畸形的、扭曲的殖民文化观,这种畸形殖民文化观念挤压并扭曲了华人本土文化。作为对殖民主义文化的反抗策略,小说展望通过加强华文文化教育,从而使华人摆脱殖民思想文化的牢笼。%Fang Beifang’s Nyonyas and Babas accuses the colonialism of its poisoning influence upon Malaysian Chinese thoughts and culture and criticizes the western colonialism. Under the sweeping influence of colonialism, Peranakans in Chinese society develop an internalized and twisted colonialist ideology, and the internalization of the colonialist ideology of Chinese Malaysians made Chinese culture so extruded and twisted that Chinese Malaysians completely forget their Chinese identity, becoming culturally rootless orphans suffer-ing aphasia. As a reaction against colonialism culture, the novel envisions a great revival of glorious Chinese culture and traditions by strengthening Chinese cultural education, so that the Chinese can liberate themselves from the colonial cage.

Embora exista grande variedade de plantas medicinais poucas têm sido investigadas com intenção de melhorar a cicatrização de órgãos e tecidos, dentre elas, a Orbignya phalerata (babaçu. OBJETIVO: Analisar comparativamente as alterações tensiométricas e histológicas na cicatrização de anastomoses colônicas proporcionadas pelo uso do extrato aquoso do mesocarpo do babaçu (Orbignya phalerata. METODOS: Utilizaram-se 40 ratos Wistar, machos, separados em dois grupos de vinte, denominados grupos controle e experimento, Os ratos de cada grupo foram divididos em dois sub-grupos de 10 animais cada e avaliados no terceiro e sétimo dia de pós-operatório. Realizaram-se colotomia e colorrafia em plano único. Os animais do grupo controle receberam no ato operatório dose única de solução salina isotônica em dose e via de administração semelhantes ao grupo experimento e os do grupo experimento receberam extrato aquoso de babaçu em dose de 50 mg/kg/peso, concentração de 25 mg/ml por via intraperitoneal. Foram analisados os seguintes parâmetros: a avaliação macroscópica da parede e cavidade abdominal; b avaliação tensiométrica da anastomose (pressão e ruptura; c características histológicas da anastomose. RESULTADOS: O exame macroscópico evidenciou a presença de aderências em todos os animais, sendo estatisticamente maior no grupo experimento de três dias quando comparados com o grupo controle. Nos animais do grupo de sete dias não houve diferença. Não houve ocorrência de deiscência de anastomose, fístulas, abscessos e/ou hemorragia.

Avaliou-se o pernil de 12 animais quanto às suas propriedades - perda de peso ao cozimento, força de cisalhamento, pH e capacidade de retenção de água-, depois extraiu-se o óleo da carne e determinou-se o perfil dos ácidos graxos. Não foram observados efeitos (P>0,05 das porcentagens de torta de babaçu sobre as propriedades da carne; os ácidos graxos (AG insaturados, mono e poli-insaturados, foram encontrados em maior quantidade (51,6-57,8% que os ácidos graxos saturados (42,2-48,4% na carne do pernil. Baseando-se na teoria de que os AG poli-insaturados ingeridos na dieta humana são responsáveis pela redução nos níveis séricos de colesterol, sugere-se que a carne de catetos seja uma boa fonte alternativa de proteína.The meat properties and the fatty acids profile of the ham of peccaries ham fed diets with different levels of babassu meal, used as an alternative energy source substituting part of corn on feeding peccaries in captivity, were studied. The ham meats of 12 animals were evaluated on their properties: cooking losses, shear force, pH, and water holding capacity. After that, the meat oil was extracted to determine the fatty acids contents. No effects (P>0.05 of the babassu meal levels on the meat properties were observed. The unsaturated fatty acids, mono and polyunsaturated, were found in higher quantity than the saturated fatty acids in the ham meat of peccaries. Based on the theory that the polyunsaturated fatty acids ingested in the human diet are responsible for reduction of the seric levels of cholesterol, it can be suggested that the peccary meat is a good alternative source of protein.

    Full Text Available A palmeira babaçu (Attalea speciosa C.Martius, Arecaceae tem grande importância socioeconômica e ecológica em grande parte da área tropical brasileira, especialmente em áreas degradadas por queimadas freqüentes na Amazônia. No entanto, ainda pouco se sabe sobre as características ecológicas desta espécie-chave. Este estudo investiga a alometria do babaçu com o objetivo de estabelecer uma metodologia eficiente na estimativa da biomassa aérea de palmeiras juvenis e adultas e para um melhor entendimento da sua arquitetura. A biomassa de palmeiras juvenis pode ser estimada facilmente e com precisão com o diâmetro mínimo das ráquis das folhas a 30 cm de extensão. A biomassa de palmeiras adultas pode ser estimada com base na altura do tronco lenhoso, também relativamente de fácil medição em campo. A biomassa foliar das palmeiras adultas foi em media 31,7% da biomassa aérea, porém houve uma alta variação e, portanto, somente pode ser estimada indiretamente através da relação entre a razão madeira:folha e biomassa aérea total. Os teores de carbono no babaçu apresentaram baixa variação, sem diferenças sistemáticas em relação ao tamanho ou estágio de crescimento, o que aponta à aplicabilidade geral dos valores 42.5% C para troncos, 39.8% C para folhas. Em conseqüência do limitado crescimento secundário do diâmetro inerente de palmeiras, não houve relação do diâmetro de tronco com a altura e a biomassa das palmeiras adultas. Observou-se que o afilamento do caule diminui com o aumento da altura das palmeiras, o que é parcialmente compensado pelo incremento da densidade de madeira em troncos quase-cilíndricos. No entanto, a altura máxima do babaçu, de cerca de 30 metros, aparentemente está definida por limitações na estabilidade mecânica. Todas as relações alométricas aqui descritas são independentes da idade da vegetação, indicando a aplicabilidade geral das relações encontradas

    Full Text Available Cet article vise à mettre en exergue l’évolution des prises de position contre le colonialisme du dessinateur Jean Bruller, futur écrivain Vercors (1902-1991, dans l’entre-deux-guerres. L’Appel des 121 que Vercors signa sans hésiter en 1960 pour clamer publiquement le droit à l'insoumission dans la guerre d'Algérie, son combat dès 1955 en faveur de l’indépendance de ce pays pourraient nous conduire à une interprétation rétrospective erronée, celle d’un homme et d’un mythe de la résistance anticolonialiste dès le début de l’entrée dans l’âge adulte et dans son parcours artistique vecteur de cette pensée. Les illustrations qu’il fournit pour la littérature de jeunesse de l’entre-deux-guerres, mais aussi l’une de ses créations personnelles prouvent au contraire que le dessinateur bascula d’une acceptation inconsciente à une interrogation critique du colonialisme du début des années vingt à la fin des années trente. De l’empan de Loulou chez les nègres à Baba Diène et Morceau-de-Sucre, nous distinguerons trois moments marqués par la publication d’ouvrages-clés pour comprendre la prise de conscience graduelle de Jean Bruller, visible dans ses choix collaboratifs comme dans les rapports entre le texte et ses dessins. Il est nécessaire de le situer dans un temps autant personnel qu’historique : celui d’un jeune homme dans un milieu éducatif et social donné, mais suffisamment attentif au monde pour avoir les moyens de s’en émanciper ; celui de l’artiste dans ses réalités symboliques et économiques, influencé par des réseaux de sociabilité correspondant à certains de ses idéaux ; celui d’artistes et d’écrivains qui s’interrogent, d’intellectuels qui prennent des positions de plus en plus tranchées au cours de ces années-là.

    Full Text Available The aim of this survey was to verify the occurrence of anti-Leptospira spp. antibodies in captive animals in the Parque Zoobotânico Arruda Câmara, João Pessoa, Paraíba State, Northeastern Brazil. Blood samples were collected from 49 animals: 26 mammals of the species Sapajus libidinosus, Cebus flavius, Saimiri sciureu, Coendu sp., Pseudalopex vetulus, Leopardus pardalis, Leopardus tigrinus, Galactitis vitata, Eira barbara, Nasua nasua, Tayassu tajacu and Ratus norvegicus; 10 birds of the species Penelope jacucaca, Pavo cristatus, Anodorhynchus hyacinthinus, Ara chlorothpterus, Pionites leucogaster, Polyborus plancus, Geranoaetus melanoleucus and Urubitinga urubitinga; and 13 reptiles of the species Caiman latirostris, Paleosuchus trigonatus, Caiman crocodilus, Tupinabis merinae, Tupinambis teguixin, Boa constrictor, Corallus hortulanus, Python molurus, Bufocephala vanderhaegei, Geochelone denticulata and Geochelone carboraria. Sera were examined by the microscopic agglutination teste (MAT using 24 serovars as antigens and cut-off point of 1:100. One ocelot (Leopardo pardalis presented positive reaction for the Icterohaemorrhagiae serovar with titer of 100, however, it did not show any clinical sign of the infection. Sinantropic rodents are the main reservoirs of this serovar, which suggests the need of maintenance and continuous evaluation of rodent control programs.

    In tropical forests, wild game meat represents an option or the only protein source for some human populations. This study analyzed the wildlife meat trade destined to human consumption in an open market of the Amazon rainforest, Brazil. Wildlife meat trade was monitored during 2005 through interviews to vendors and consumers in order to evaluate the socioeconomic profile of the sellers, the main species and byproducts sold, their geographical origin, commercial value, frequency of sale and product demand. Data indicated that vendors were financially highly dependant of this activity, getting a monthly income up to US$271.49. During the survey, the amount of wildlife meat on sale added a total of 5 970kg, as follows: 63.2% capybara (Hydrochoerus hydrochaeris), 34.4% cayman (Melanosuchus niger and/or Caiman crocodilus crocodilus), 1.1% paca (Cuniculus paca); 0.6% armadillo (Dasypus novemcinctus), 0.5% deer (Mazama americana), 0.2% matamata (Chelus fimbriatus), and 0.1% opossum (Didelphis marsupialis). Most of the commercialized species were not slaughtered locally. The consumption of wildlife meat was admitted by 94% of the interviewed, consisting of 27 ethno-species: 19 mammals, 6 reptiles, and 2 birds. The same percentage of the interviewed (94%) already bought wildlife meat of 18 species: 12 mammals and 6 reptiles. The great amount of wildlife meat traded and the important demand for these products by the local population, point out the necessity to adopt policies for a sustainable management of cinegetic species, guaranteeing the conservation of the environment, the improvement of living standards, and the maintenance of the local culture.

    Roads directly or indirectly affect the structure, dynamics and function of ecosystems that they traverse. Most studies on the effect of roads on wildlife focus on the evaluation of mortality of vertebrates by vehicle collisions. Despite the extensive road network that exists in Venezuela, studies of wildlife mortality in them are scarce. In this paper, we analyzed the temporal and spatial pattern of vertebrate's collisions along the road Guanare-Guanarito, in Portuguesa state. We travelled 26 times between these towns (74 km) to localize dead vertebrates, at a speed of 50-60km/h. of those trips were conducted from March 13 to October 26, 2010, and 10 additional trips from December 7, 2009 to December 14, 2010; these ones, with the aim to include months and seasons that were insufficiently sampled during the first period. The elapsed time between trips varied from 14 to 37 days. The total distance traveled was 1 924 km. Dead animals found amounted 464 individuals, 66 of them were birds (25 identified species), 130 mammals (15 species) and 268 reptiles (18 species). The species with the highest number of individuals were the snake Leptodeira annulata (n=119), the oppossum Didelphis marsupialis (n=39) and the spectacled caiman Caiman crocodilus (n=33). Excluding domestic animals, the rate of road-killed vertebrates was 0.2282 indiv./km, a figure 28.3% higher than previous studies in the same road. Changes in the relative number of collisions for some species, respect to the numbers reported 20 years ago, were linked to the increase in traffic flow and changes in land use. Road segments with collision rates higher than expected by chance were identified. Collition by cars may be the principal cause of mortality for species like the tamandua (Tamandua tetradactyla) and the giant anteater (Myrmecophaga tridactyla), the last considered a vulnerable species. Some basic measures are proposed to reduce wildlife mortality on the road. PMID:24432523

    Full Text Available The purpose of this study was to identify and describe the experiences of the parents of an ill premature infant in order to identify the needs of the parents going through this potential crisis. As a result of the constant medical and technological progress the percentage of premature infants is continually increasing. It is therefore of vital importance that the nursing and other medical staff are made aware of the trauma that these parents experience. This will enable them in giving adequate support and accompaniment in the prevention of social pathology.

    Purussaurus brasiliensis thrived in the northwestern portion of South America during the Late Miocene. Although substantial material has been recovered since its early discovery, this fossil crocodilian can still be considered as very poorly understood. In the present work, we used regression equations based on modern crocodilians to present novel details about the morphometry, bite-force and paleobiology of this species. According to our results, an adult Purussaurus brasiliensis was estimated to reach around 12.5 m in length, weighing around 8.4 metric tons, with a mean daily food intake of 40.6 kg. It was capable of generating sustained bite forces of 69,000 N (around 7 metric tons-force). The extreme size and strength reached by this animal seems to have allowed it to include a wide range of prey in its diet, making it a top predator in its ecosystem. As an adult, it would have preyed upon large to very large vertebrates, and, being unmatched by any other carnivore, it avoided competition. The evolution of a large body size granted P. brasiliensis many advantages, but it may also have led to its vulnerability. The constantly changing environment on a large geological scale may have reduced its long-term survival, favoring smaller species more resilient to ecological shifts. PMID:25689140

  2. Similarity of Crocodilian and Avian Lungs Indicates Unidirectional Flow Is Ancestral for Archosaurs.

    Patterns of airflow and pulmonary anatomy were studied in the American alligator (Alligator mississippiensis), the black caiman (Melanosuchus niger), the spectacled caiman (Caiman crocodilus), the dwarf crocodile (Osteolaemus tetraspis), the saltwater crocodile (Crocodylus porosus), the Nile crocodile (Crocodylus niloticus), and Morelet's crocodile (Crocodylus moreletii). In addition, anatomy was studied in the Orinoco crocodile (Crocodylus intermedius). Airflow was measured using heated thermistor flow meters and visualized by endoscopy during insufflation of aerosolized propolene glycol and glycerol. Computed tomography and gross dissection were used to visualize the anatomy. In all species studied a bird-like pattern of unidirectional flow was present, in which air flowed caudad in the cervical ventral bronchus and its branches during both lung inflation and deflation and craniad in dorsobronchi and their branches. Tubular pathways connected the secondary bronchi to each other and allowed air to flow from the dorsobronchi into the ventrobronchi. No evidence for anatomical valves was found, suggesting that aerodynamic valves cause the unidirectional flow. In vivo data from the American alligator showed that unidirectional flow is present during periods of breath-holding (apnea) and is powered by the beating heart, suggesting that this pattern of flow harnesses the heart as a pump for air. Unidirectional flow may also facilitate washout of stale gases from the lung, reducing the cost of breathing, respiratory evaporative water loss, heat loss through the heat of vaporization, and facilitating crypsis. The similarity in structure and function of the bird lung with pulmonary anatomy of this broad range of crocodilian species indicates that a similar morphology and pattern of unidirectional flow were present in the lungs of the common ancestor of crocodilians and birds. These data suggest a paradigm shift is needed in our understanding of the evolution of this

    Full Text Available No controlled studies have been conducted to determine the predilection muscles of Trichinella zimbabwensis larvae in Nile crocodiles (Crocodylus niloticus or the influence of infection intensity on the distribution of the larvae in crocodiles. The distribution of larvae in muscles of naturally infected Nile crocodiles and experimentally infected caimans (Caiman crocodilus and varans (Varanus exanthematicus have been reported in literature. To determine the distribution patterns of T. zimbabwensis larvae and predilection muscles, 15 crocodiles were randomly divided into three cohorts of five animals each, representing high infection (642 larvae/kg of bodyweight average, medium infection (414 larvae/kg of bodyweight average and low infection (134 larvae/kg of bodyweight average cohorts. In the high infection cohort, high percentages of larvae were observed in the triceps muscles (26% and hind limb muscles (13%. In the medium infection cohort, high percentages of larvae were found in the triceps muscles (50%, sternomastoid (18% and hind limb muscles (13%. In the low infection cohort, larvae were mainly found in the intercostal muscles (36%, longissimus complex (27%, forelimb muscles (20% and hind limb muscles (10%. Predilection muscles in the high and medium infection cohorts were similar to those reported in naturally infected crocodiles despite changes in infection intensity. The high infection cohort had significantly higher numbers of larvae in the sternomastoid, triceps, intercostal, longissimus complex, external tibial flexor, longissimus caudalis and caudal femoral muscles (p < 0.05 compared with the medium infection cohort. In comparison with the low infection cohort, the high infection cohort harboured significantly higher numbers of larvae in all muscles (p < 0.05 except for the tongue.

    Full Text Available The genus Paramunida belongs to the most diverse family of galatheoids and it is commonly reported from the continental slope across the Indian and Pacific Oceans. Examination of material collected by the NOAA RV Townsend Cromwell Cruise near Christmas (Kiritimati Island, Kiribati, revealed the existence of a new species of Paramunida (P. haigae, which represents the fourth record of the genus for the Central Pacific. Furthermore, recent efforts to unravel phylogenetic relationships and diversification patterns in Paramunida revealed P. granulata (Henderson, 1885 to be the most basally diverging taxon within the genus. This species is clearly distinguished from other species of Paramunida by the spinulation of the carapace and the length of the distomesial spine of the second antennal peduncle article, which in combination with a high level of genetic divergence suggest that this species represents a separate monotypic lineage. A new genus, Hendersonida gen. n., is proposed to accommodate this species based on morphological and molecular evidence. An updated dichotomous identification key for all species of Paramunida is presented.

    β-Aminobutyric acid (BABA) is known to induce resistance to microbial pathogens, nematodes and insects in several host plant/pest systems. The present study was undertaken to determine whether a similar effect of BABA occurred against the Asian citrus psyllid, Diaphorina citri Kuwayama, in citrus. A 25 mM drench application of BABA significantly reduced the number of eggs/plant as compared with a water control, whereas 200 and 100 mM applications of BABA reduced the numbers of nymphs/plant and adults/plants, respectively. A 5 mM foliar application of BABA significantly reduced the number of adults but not eggs or nymphs when compared with a water control treatment. In addition, leaf-dip bioassays using various concentrations (25–500 mM) of BABA indicated no direct toxic effect on 2nd and 5th instar nymphs or adult D. citri. BABA-treated plants were characterized by significantly lower levels of iron, magnesium, phosphorus, sodium, sulfur and zinc as compared with control plants. The expression level of the PR-2 gene (β-1,3-glucanase) in BABA-treated plants that were also damaged by D. citri adult feeding was significantly higher than in plants exposed to BABA, D. citri feeding alone or control plants. Our results indicate the potential for using BABA as a systemic acquired resistance management tool for D. citri.

    [Objective] This study was to understand the effects of β-Amino butyric acid(abbreviated as BABA) induced rice blast resistance on reactive oxygen metabolism. [Method] Using the cultivar Chaochan 2 that is highly susceptible to disease as experimental material, the changes of catalase(CAT), and superoxide dismutase(SOD) and MDA activities in rice treated by BABA were investigated. [Result] In rice plants treated by BABA, the activities of CAT and SOD increased, meanwhile the MDA content also rose to some extent, resulting in the disease resistance to rice blast.

    The present study highlights the role of β-aminobutyric acid (BABA) in alleviating drought stress effects in maize (Zea mays L.). Chemical priming was imposed by pretreating 1-week-old plants with 600 μM BABA prior to applying drought stress. Specific activities of key antioxidant enzymes and metabolites (ascorbate and glutathione) levels of ascorbate-glutathione cycle were studied to unravel the priming-induced modulation of plant defense system. Furthermore, changes in endogenous ABA and JA concentrations as well as mRNA expressions of key genes involved in their respective biosynthesis pathways were monitored in BABA-primed (BABA+) and non-primed (BABA-) leaves of drought-challenged plants to better understand the mechanistic insights into the BABA-induced hormonal regulation of plant response to water-deficit stress. Accelerated stomatal closure, high relative water content, and less membrane damage were observed in BABA-primed leaves under water-deficit condition. Elevated APX and SOD activity in non-primed leaves found to be insufficient to scavenge all H2O2 and O2 (·-) resulting in oxidative burst as evident after histochemical staining with NBT and DAB. A higher proline accumulation in non-primed leaves also does not give much protection against drought stress. Increased GR activity supported with the enhanced mRNA and protein expressions might help the BABA-primed plants to maintain a high GSH pool essential for sustaining balanced redox status to counter drought-induced oxidative stress damages. Hormonal analysis suggests that in maize, BABA-potentiated drought tolerance is primarily mediated through JA-dependent pathway by the activation of antioxidant defense systems while ABA biosynthesis pathway also plays an important role in fine-tuning of drought stress response.

    The strength of binding between the Helicobacter pylori blood group antigen-binding adhesin (BabA) and its cognate glycan receptor, the Lewis b blood group antigen (Le(b)), was measured by means of atomic force microscopy. High-resolution measurements of rupture forces between single receptor-ligand pairs were performed between the purified BabA and immobilized Le(b) structures on self-assembled monolayers. Dynamic force spectroscopy revealed two similar but statistically different bond populations. These findings suggest that the BabA may form different adhesive attachments to the gastric mucosa in ways that enhance the efficiency and stability of bacterial adhesion.

    This report documents primate communities at two sites within Noel Kempff Mercado National Park in northeastern Santa Cruz Department, Bolivia. Diurnal line transects and incidental observations were employed to survey two field sites, Lago Caiman and Las Gamas, providing information on primate diversity, habitat preferences, relative abundance, and population density. Primate diversity at both sites was not particularly high, with six observed species: Callithrix argentata melanura, Aotus azarae, Cebus apella, Alouatta caraya, A. seniculus, and Ateles paniscus chamek. Cebus showed no significant habitat preferences at Lago Caiman and was also more generalist in use of forest strata, whereas Ateles clearly preferred the upper levels of structurally tall forest. Callithrix argentata melanura was rarely encountered during surveys at Lago Caiman, where it preferred low vine forest. Both species of Alouatta showed restricted habitat use and were sympatric in Igapo forest in the Lago Caiman area. The most abundant primate at both field sites was Ateles, with density estimates reaching 32.1 individuals/km2 in the lowland forest at Lago Caiman, compared to 14.1 individuals/km2 for Cebus. Both Ateles and Cebus were absent from smaller patches of gallery forest at Las Gamas. These densities are compared with estimates from other Neotropical sites. The diversity of habitats and their different floristic composition may account for the numerical dominance of Ateles within the primate communities at both sites. PMID:9802511

    Full Text Available ABSTRACTThis current study was conducted to examine parental communication and perceived parental attitudes about sexuality with respect to gender among Turkish college students. Moreover, attitudes toward premarital sexuality with respect to gender were explored. A demographic data form, premarital sexual permissiveness scale, parental communication about sexuality scale and parental attitudes about sexuality scale were administered to 366 (217 female and 148 male college students, aged 18 to 26. The results indicated that females held more conservative premarital sexual attitudes than males; females talked to their mothers, while males talked to their fathers more about sexuality issues. Furthermore, the results demonstrated that gender was significant on the perceived maternal attitudes about sexuality, whereas perceived paternal attitudes about sexuality were not found to be significant with respect to gender. Future research is needed to explore variables that may contribute to the differences in parental communication and perceived parental attitudes about sexuality.

    Full Text Available INTRODUÇÃO: A cicatrização constitui processo complexo, envolvendo diferentes sistemas biológicos e imunológicos, sendo essencial para manter a integridade do organismo. Três fases bem definidas ocorrem: inflamatória, proliferativa e maturação. Falha ou prolongamento em uma delas pode resultar em retardo ou ausência da cicatrização. OBJETIVO: Analisar comparativamente as alterações histológicas proporcionadas pelo uso do extrato aquoso da Orbignya phalerata na cicatrização de lesões cirúrgicas da bexiga. MÉTODOS: Quarenta ratos da linhagem Wistar, adultos e machos foram utilizados. O procedimento experimental constituiu-se em incisão longitudinal de 2cm na bexiga e síntese em plano único com pontos separados de poliglactina 910 cinco zeros. Após este procedimento comum, os animais foram distribuídos aleatoriamente em dois subgrupos contendo 20 animais cada. No grupo controle não foi utilizada a substância Orbignya phalerata. No grupo-experimento utilizou-se solução aquosa de Orbignya phalerata na dose de 50mg/kg por via intraperitoneal. Os animais foram acompanhados e mortos em três e sete dias. Foi feita análise histológica comparativa entre os grupos. RESULTADOS: Os resultados mostraram que foi observada diferença estatística significante nas variáveis neoformação (p= 0,001 e proliferação fibroblástica (p= 0,010 nos subgrupos controle e experimento do 3º dia. Ainda no grupo experimento a neoformação capilar foi mais intensa que no grupo controle, apresentando significância estatística. No grupo de sete dias observou-se que as variáveis inflamação aguda (p= 0,001, inflamação crônica (p= 0,002 e proliferação fibroblástica (p=0,023 apresentaram significância estatística, sendo bem evidente a inflamação aguda no grupo controle. CONCLUSÃO: Foi observada homogeneidade no fator tempo da cicatrização nos grupos experimento e controle sendo mais rápida no grupo experimento. Houve efeito favorecedor cicatrizante na utilização do extrato aquoso do mesocarpo da Orbignya phalerata na bexiga do ratos.INTRODUCTION: Wound healing is a complex process that deals with different biological and immunological systems and is essential to keep the organism integrity. Three well-defined phases occur: inflammatory, proliferative and maturation. A failure or lengthy phase may result in a delay or absence of it. PURPOSE: The aim of this paper is to analyse comparatively the histological alteration provided by the use of the aqueous extract of Orbignya phalerata, in the healing process of bladder surgical wounds. METHODS: Forty adult, male Wistar rats were used. The experimental procedure consisted of a longitudinal 2cm long bladder incision and single layer interrupted suture of 5-0 poliglactine 910. Post-operatively, the rats were randomly divided into two groups of 20. The substance was not used in the control group. The Orbignya phalerata aqueous solution was used in the study group. The animals were observed and killed three and seven days later. Comparative histological analysis was accomplished between the groups. Resuts: Significant statistical differences were observed in the neo-formation variables (p= 0,001, chronic inflammation (p= 0,002 and fibroblastic proliferation (p= 0,023. Acute inflammation was very evident in the control group. CONCLUSION: The time factor of wound healing showed homogeneity between experimental and control groups, however faster in the experimental one. The Orbignya phalerata had a favoring healing effect in the surgical incision on rats bladder.

  5. Soil drench treatment with ß-aminobutyric acid increases drought tolerance of potato.

    Directory of Open Access Journals (Sweden)

    Anita Sós-Hegedűs

    Full Text Available The non-protein amino acid β-aminobutyric acid (BABA is known to be a priming agent for a more efficient activation of cellular defence responses and a potent inducer of resistance against biotic and abiotic stresses in plants. Nevertheless, most of the studies on priming have been carried out in Arabidopsis. In potato, the effect of BABA was demonstrated only on biotic stress tolerance. We investigated the effect of BABA on the drought tolerance of potato and found that soil drenched with BABA at a final concentration of 0.3 mM improves the drought tolerance of potato. Water loss from the leaves of the primed plants is attenuated and the yield is increased compared to the unprimed drought-stressed plants. The metabolite composition of the tubers of the BABA-treated plants is less affected by drought than the tuber composition of the non-treated plants. Nitric oxide and ROS (reactive oxygen species production is increased in the BABA-treated roots but not in the leaves. In the leaves of the BABA-treated plants, the expression of the drought-inducible gene StDS2 is delayed, but the expression of ETR1, encoding an ethylene receptor, is maintained for a longer period under the drought conditions than in the leaves of the non-treated, drought-stressed control plants. This result suggests that the ethylene-inducible gene expression remains suppressed in primed plants leading to a longer leaf life and increased tuber yield compared to the non-treated, drought-stressed plants. The priming effect of BABA in potato, however, is transient and reverts to an unprimed state within a few weeks.

    Full Text Available Priming can improve plant innate capability to deal with the stresses caused by both biotic and abiotic factors. In this study, the effect of DL-β-amino-n-butyric acid (BABA against Aphis glycines Matsumura, the soybean aphid (SA was evaluated. We found that 25 mM BABA as a root drench had minimal adverse impact on plant growth and also efficiently protected soybean from SA infestation. In both choice and non-choice tests, SA number was significantly decreased to a low level in soybean seedlings drenched with 25 mM BABA compared to the control counterparts. BABA treatment resulted in a significant increase in the activities of several defense enzymes, such as phenylalanine ammonia-lyase (PAL, peroxidase (POX, polyphenol oxidase (PPO, chitinase (CHI, and β-1, 3-glucanase (GLU in soybean seedlings attacked by aphid. Meanwhile, the induction of 15 defense-related genes by aphid, such as AOS, CHS, MMP2, NPR1-1, NPR1-2, and PR genes, were significantly augmented in BABA-treated soybean seedlings. Our study suggest that BABA application is a promising way to enhance soybean resistance against SA.

    Full Text Available Abstract Background Intragenomic recombination between babA and babB mediates antigenic variations and may help H. pylori colonization. This study determined whether variable genotypes of babA and babB correlate to different clinical disease outcomes, and can distribute over the different gastric niches. Results This study enrolled 92 clinical strains (45 from peptic ulcer, 27 from gastritis, and 20 from gastric cancer to detect whether the babA and babB are at locus A or B by PCR reactions using the primers designed from the upstream and variable region of the babA and babB genes. Four genotypes of babA and babB (A B, AB B, A AB, AB AB were found. The distribution of the 4 genotypes in 92 clinical strains was significantly different among patients with different gastric diseases (p vs. 9.7%, p p p > 0.05. Besides, the study enrolled 19 patients to verify whether variable genotypes of babAB existed in the different gastric niches. Among the patients infected with more than one babAB genotypes over antrum and corpus, there were higher rate of genotypes as A B or AB AB in isolates from antrum than in those from corpus (75.0 % vs. 16.7%, p  Conclusions The H. pylori isolate with the AB AB genotype correlates with an increased gastric cancer risk, and colonize in an antrum predominant manner.

    The Helicobacter pylori adhesin BabA binds mucosal ABO/Le(b) blood group (bg) carbohydrates. BabA facilitates bacterial attachment to gastric surfaces, increasing strain virulence and forming a recognized risk factor for peptic ulcers and gastric cancer. High sequence variation causes BabA functional diversity, but the underlying structural-molecular determinants are unknown. We generated X-ray structures of representative BabA isoforms that reveal a polymorphic, three-pronged Le(b) binding site. Two diversity loops, DL1 and DL2, provide adaptive control to binding affinity, notably ABO versus O bg preference. H. pylori strains can switch bg preference with single DL1 amino acid substitutions, and can coexpress functionally divergent BabA isoforms. The anchor point for receptor binding is the embrace of an ABO fucose residue by a disulfide-clasped loop, which is inactivated by reduction. Treatment with the redox-active pharmaceutic N-acetylcysteine lowers gastric mucosal neutrophil infiltration in H. pylori-infected Le(b)-expressing mice, providing perspectives on possible H. pylori eradication therapies.

    Full Text Available Citrus bacterial canker, caused by Xanthomonas citri subsp. citri (Xcc, is a destructive disease. So far used chemicals to control this pathogen are either not effective or have harmful effects on the environment. To improve control of this disease, lime (Citrus aurantifolia plants inoculated with Xcc were treated with β-Aminobutyric Acid (BABA, ascorbic acid (vitamin C, thiamin (vitamin B1, green tea (Camellia sinensis, copper oxychloride and distilled water. Lesion diameters of inoculated leaves were evaluated twenty days after treatment. The results showed that BABA and green tea had inhibitory effects on disease development. None of the agents used for plant treatment had direct antimicrobial activity on Xcc, except copper oxychloride. This indicated that the inhibitory effects of BABA and green tea resulted from strengthening the defense capacities of the plant. To support this claim, partial coding sequences of Pathogenesis-Related (PR genes from lime were cloned and sequenced. Analysis of PR gene expression showed increased mRNA levels of β-1,3-glucanase and chitinase, during disease development. Reduction in lesion size and lack of antimicrobial activity indicate that BABA and green tea might be useful treatments against Xcc infection.

    The effectiveness of postharvest β-aminobutyric acid(BABA)treatment was studied for inducing resistance against dry rot caused by Fusarium sulphureum in tubers and slices of two potato cultivars(resistant cultivar Shepody and susceptible cultivar Xindaping).The results showed that BABA at 100 mmol L-1 significantly reduced lesion diameter in inoculated both tubers and slices.The chemical at 100 mmol L-1 showed an effective reduction in infection ability of F.sulphureum inoculated 48 and 72 h after treatment in slices of resistant cultivar,and 72 and 96 h in susceptible ones.BABA increased the activitives of peroxidase(POD),polyphenoloxidase(PPO)and phenylalanine ammonialyase(PAL),and accumulated the contents of lignin,flavonoids and phenolics in slices.The resistant cultivar had a stronger resistant response than the susceptible one.These findings suggest that the BABA treatment can induce the resistance in potato tubers,however,the inducing degree depends on the original level of resistance present in each cultivar.

    Purpose Obesity is associated with a number of medical comorbidities and is considered a risk factor for surgical complications. The purpose of this study was to analyze the influence of body habitus including obesity on the surgical outcomes of the Bilateral axillo-breast approach (BABA) robotic thyroidectomy (RoT) in papillary thyroid carcinoma (PTC) patients. Methods The medical records of 456 PTC patients who underwent BABA RoT between January 2011 and December 2012 were reviewed, and 310 women PTC patients who had undergone BABA robotic total thyroidectomy with central lymph node dissection were examined. Body habitus were evaluated by measuring body mass index (BMI), body surface area, and neck circumference. We divided the patients into BMI < 25 kg/m2 and BMI ≥ 25 kg/m2 groups. Clinicopathological data, surgical outcomes, and postoperative complications were evaluated. Results Clinicopathological characteristics did not differ between the 2 BMI groups. The creation of working space time (P = 0.210) and other surgical outcomes showed no significant differences between the groups. There were no statistically significant differences between body habitus indexes and postoperative length of hospital stay, number of retrieved central lymph nodes, postoperative thyroglobulin levels, occurrence of hypoparathyoidism, recurrent laryngeal nerve injury and wound complication. Conclusion Patient with large body habitus undergoing BABA RoT were not at an increased risk of surgical complications and showed good surgical outcomes. BABA RoT may be a good alternative operative method for PTC patients for whom cosmetic outcome is an important consideration.

    Based on light and scanning electron microscopical studies, the following five species of the Philometridae (Nematoda: Dracunculoidea) are described from female specimens collected from marine fishes off the southwestern coast of Java, Indonesia: Philometra lobotidis sp. n. from the abdominal cavity of the Atlantic tripletail Lobotes surinamensis (Bloch) (Lobotidae, Perciformes); Philometra javaensis sp. n. from the abdominal cavity of the immaculate puffer Arothron immaculatus (Bloch et Schneider) (Tetraodontidae, Tetraodontiformes); Philometra psettoditis sp. n. from the musculature of the Indian spiny turbot Psettodes erumei (Bloch et Schneider) (Psettodidae, Pleuronectiformes); Philometroides indonesiensis sp. n. from the musculature of the hound needlefish Tylosurus crocodilus crocodilus (Péron et Lesueur) (Belonidae, Beloniformes); and Philometroides trichiuri sp. n. from the dorsal fin of the largehead hairtail Trichiurus lepturus Linnaeus (type host) and the savalai hairtail Lepturacanthus savala (Cuvier) (both Trichiuridae, Perciformes). All these new species are distinguished from their congeners parasitizing marine fishes by morphological (mainly the shape and structure of the cephalic and caudal ends and of the oesophagus) and biometrical features. Besides previously known Philometra pellucida (Jägerskiöld, 1893) and Philometra ocularis Moravec, Ogawa, Suzuki, Miyazaki et Donai, 2002, they are the only nominal philometrid species recorded from Indonesian waters.

  2. Mothers’ access to supportive hospital services after the loss of a baby through stillbirth or neonatal death

    Full Text Available Every year, 3-5% of pregnant mothers in South Africa lose their babies to a stillbirth or neonatal death. These mothers need adequate services to prevent complications in their grieving process. Most of these babies are lost in hospital settings, so the treatment medical staff provide is vital. This study examined mothers’ experiences of accessing hospital, religious, formal and social services after a stillbirth or neonatal death. An exploratory research design was used to conduct applied research. A semi-structured interview schedule was used with a sample of 15 mothers who had lost a baby in the last 5 years. The findings were analysed quantitatively and qualitatively. The primary focus of this article is the quantitative findings relating to hospital services. The sample was small and these results cannot be generalised, but some conclusions are reached and recommendations are made to service providers in hospitals working with mothers who have lost babies. Mothers generally experienced the support services from hospitals as inadequate, compared to what hospitals could offer. Mothers that receive support after the loss of a baby generally cope better. This support thus assists them in the grieving process. Hospital staff can be trained to provide these services. Opsomming In Suid-Afrika verloor 3-5% swanger moeders hulle babas deur stilgeboorte of neonatale dood. Hierdie moeders benodig voldoende dienste om komplikasies in die rouproses te verhoed. Die behandeling deur mediese personeel is uiters belangrik omdat die meeste van dié babas in ‘n hospitaalopset sterf. Hierdie studie het moeders se ervarings van die toeganklikheid van hospitaal-, godsdienstige, formele en sosiale dienste na die dood van hulle babas deur stilgeboorte of neonatale dood ondersoek. Toegepaste navorsing is met behulp van ‘n verkennende navorsingsontwerp gedoen. ‘n Semi-gestruktureerde onderhoudskedule is gebruik met ‘n steekproef van 15 moeders wat

    2015-12-01

    Full Text Available Some animated movies use humor to capture the full attention of its audience. In so doing, the movie’s messages have become a great concern for many theorists and critics by virtue of the idea that a movie can be a repository of ideologies meant to construct a certain type of easy-going and noncritical audience. This paper, therefore, takes the example of Max Fleischer’s Popeye the Sailor Meets Ali Baba and his Forty Thieves (1937 and Robert Clampett’s Ali Baba Bound (1941 as its case studies aiming at spotting the different manifestations of humor, taking Arabs as its subject-matter, becoming a leaked ideology and taming the discourse that is amplified, manipulated, and delivered to the Western public in unwarrantable ways compared to the imagery of Westerners.

    2013-01-01

    [Introduction] Islamic finance has been developing steadily in the last decades since the 1970s, yet for most parts its growth was concentrated in the Arab states and in several south-east Asian parts of the world with a Muslim majority (Malaysia in particular). Perhaps the only exceptions to that were global financial centers like London or New York that serve as organizational hubs to channel and direct Islamic financial resources (Baba 2007). In comparison with that, in Central Asia Islami...

    Full Text Available Fruit extracts from black currants (Ribes nigrum L. are traditionally used for treatment of gastritis based on seed polysaccharides that inhibit the adhesion of Helicobacter pylori to stomach cells. For detailed investigations an arabinogalactan protein (F2 was isolated from seeds and characterized concerning molecular weight, carbohydrate, amino acid composition, linkage, configuration and reaction with β-glucosyl Yariv. Functional testing of F2 was performed by semiquantitative in situ adhesion assay on sections of human gastric mucosa and by quantitative in vitro adhesion assay with FITC-labled H. pylori strain J99 and human stomach AGS cells. Bacterial adhesins affected were identified by overlay assay with immobilized ligands. 125I-radiolabeled F2 served for binding studies to H. pylori and interaction experiments with BabA and SabA. F2 had no cytotoxic effects against H. pylori and AGS cells; but inhibited bacterial binding to human gastric cells. F2 inhibited the binding of BabA and fibronectin-binding adhesin to its specific ligands. Radiolabeled F2 bound non-specifically to different strains of H. pylori; and to BabA deficient mutant. F2 did not lead to subsequent feedback regulation or increased expression of adhesins or virulence factors. From these data the non-specific interactions between F2 and the H. pylori lead to moderate antiadhesive effects.

    Myctophids (lantern fish) and cephalopods play a key role in trophic webs from the continental slope and oceanic waters linking the zooplankton to top predators. Many cetaceans feed on both lantern fish and cephalopods, and such prey would thus be expected to bridge the trophic gap in the life-cycles of helminths infecting cetaceans. However, information on the life-cycles of most of these helminths is extremely scanty. We examined the parasite fauna of myctophids and cephalopods in two areas from the western Mediterranean where at least 21 helminth taxa from cetaceans have been reported and both cetacean diversity and abundance is high. A total of 1012 individuals of 8 lantern fish species, namely, Ceratoscopelus maderensis, Lampanyctus crocodilus, Notoscopelus elongatus, Benthosema glaciale, Myctophum punctatum, Lobianchia dofleini, Diaphus holti and Hygophum benoiti, and 792 individuals of 2 cephalopod species, Alloteuthis media and Sepietta oweniana, were collected from the Gulf of Valencia and Alboran Sea (Spanish Mediterranean) during 2010-2012 and examined for larval helminths. All these species have been reported as prey for at least some cetacean species in the area. Only five helminth taxa were found. The nematodes Anisakis pegreffii and Anisakis physeteris were detected in N. elongatus and C. maderensis (overall prevalence for Anisakis: 8.1% and 0.5%, respectively). Their prevalence in N. elongatus was significantly higher than that from the other three myctophid species with n>50 individuals. A single individual of Hysterothylacium sp. was found in N. elongatus (prevalence: 0.5%) and Raphidascarididae gen. spp. in N. elongatus and L. crocodilus (prevalence: 20.3% and 0.7%, respectively). Juvenile didymozoid digeneans (Torticaecum type) were detected in N. elongatus and L. crocodilus (prevalence: 18.5% and 4.3%, respectively). Two unidentified cestode plerocercoids were collected from N. elongatus. Our study suggests, for the first time, that myctophids

    The effects ofβ-aminobutyric acid (BABA) treatment on postharvest grey mold decay, the activities of defense-related enzymes and total phenolics content in Kyoho grapes were investigated. The grape fruits were pretreated with 75 mmol/L BABA, inoculated with Botrytis cinerea, and then stored at 25 ℃ for 60 h. The results showed that BABA treatment resulted in significantly lower disease incidence and smaller lesion diameter compared with the control fruit. Meanwhile, BABA treatment enhanced the activities of defense-related enzymes including chitinase, β-1,3 glucanase, phenylalanine ammonia-lyase, 4-coumarate coenzyme A ligase and cinnamate-4-hydroxylase and increased the content of total phenolics. These results suggest that BABA treatment can reduce the incidence and severity of gray mold decay by inducing disease resistance in grapes.%以‘巨峰’葡萄果实为实验材料,研究β-氨基丁酸(β-aminobutyric acid,BABA)处理对葡萄果实灰霉病、抗病相关酶活性和总酚含量的影响。葡萄果实先用75 mmol/L的BABA溶液处理后刺伤接种灰霉葡萄孢菌,然后转入25℃贮藏60 h。结果发现,BABA处理有效抑制了‘巨峰’葡萄果实的腐烂和病斑的扩展;同时BABA处理还诱导了果实中几丁质酶、β-1,3葡聚糖酶、苯丙氨酸解氨酶、4-香豆酸辅酶A连接酶和肉桂酸羟化酶等抗病相关酶活性以及总酚含量的提高。结果表明,BABA可诱导葡萄果实产生抗病性,从而减少灰霉病的发生。

    The first description of the male and a redescription of the female of the nematode Paratrichosoma recurvum (Solger, 1877), a parasite of the abdominal skin of crocodiles, are presented on the basis of specimens collected from Crocodilus moreletii Duméril et Bibron from the Lagoon of Celestún, Yucatan, Mexico. The morphology of P. recurvum proved to be very similar to that of the only other congeneric species, P. crocodylus Ashford et Muller, 1978, but the former differed from the latter in having distinctly protruding polar plugs on eggs, reduced mesenchymal cells at the esophagointestinal junction, and a smooth spicular surface as well as in geographic distribution. The finding of P. recurvum in C. moreletii represents a new host record. Paratrichosoma spp. appear to be widely distributed in tropical countries of different continents and may be of economic importance for crocodile farms. PMID:9660141

    Large cats feeding habits have been studied through two main methods: scat analysis and the carcasses of prey killed by monitored animals. From November 2001 to April 2004, we studied jaguar predation patterns using GPS telemetry location clusters on a cattle ranch in southern Pantanal. During this period, we recorded 431 carcasses of animals preyed upon by monitored jaguars. Concurrently, we collected 125 jaguar scats opportunistically. We compared the frequencies of prey found through each method. We also compared the prey communities using Bray-Curtis similarity coefficient. These comparisons allowed us to evaluate the use of scat analysis as a means to describe jaguar feeding habits. Both approaches identified prey communities with high similarity (Bray-Curtis coefficient > 70). According to either method, jaguars consume three main prey: cattle (Bos taurus), caiman (Caiman yacare) and peccaries (Tayassu pecari and Pecari tajacu). The two methods did not differ in the frequency of the three main prey over dry and wet seasons or years sampled. Our results show that scat analysis is effective and capable of describing jaguar feeding habits.

    Amazonia contains one of the world's richest biotas, but origins of this diversity remain obscure. Onset of the Amazon River drainage at approximately 10.5 Ma represented a major shift in Neotropical ecosystems, and proto-Amazonian biotas just prior to this pivotal episode are integral to understanding origins of Amazonian biodiversity, yet vertebrate fossil evidence is extraordinarily rare. Two new species-rich bonebeds from late Middle Miocene proto-Amazonian deposits of northeastern Peru document the same hyperdiverse assemblage of seven co-occurring crocodylian species. Besides the large-bodied Purussaurus and Mourasuchus, all other crocodylians are new taxa, including a stem caiman—Gnatusuchus pebasensis—bearing a massive shovel-shaped mandible, procumbent anterior and globular posterior teeth, and a mammal-like diastema. This unusual species is an extreme exemplar of a radiation of small caimans with crushing dentitions recording peculiar feeding strategies correlated with a peak in proto-Amazonian molluscan diversity and abundance. These faunas evolved within dysoxic marshes and swamps of the long-lived Pebas Mega-Wetland System and declined with inception of the transcontinental Amazon drainage, favouring diversification of longirostrine crocodylians and more modern generalist-feeding caimans. The rise and demise of distinctive, highly productive aquatic ecosystems substantially influenced evolution of Amazonian biodiversity hotspots of crocodylians and other organisms throughout the Neogene.

    Full Text Available The Pantanal hosts diverse wildlife species and therefore is a hotspot for arbovirus studies in South America. A serosurvey for Mayaro virus (MAYV, eastern (EEEV, western (WEEV and Venezuelan (VEEV equine encephalitis viruses was conducted with 237 sheep, 87 free-ranging caimans and 748 equids, including 37 collected from a ranch where a neurologic disorder outbreak had been recently reported. Sera were tested for specific viral antibodies using plaque-reduction neutralisation test. From a total of 748 equids, of which 264 were immunised with vaccine composed of EEEV and WEEV and 484 had no history of immunisation, 10 (1.3% were seropositive for MAYV and two (0.3% for VEEV using criteria of a ≥ 4-fold antibody titre difference. Among the 484 equids without history of immunisation, 48 (9.9% were seropositive for EEEV and four (0.8% for WEEV using the same criteria. Among the sheep, five were sero- positive for equine encephalitis alphaviruses, with one (0.4% for EEEV, one (0.4% for WEEV and three (1.3% for VEEV. Regarding free-ranging caimans, one (1.1% and three (3.4%, respectively, had low titres for neutralising antibodies to VEEV and undetermined alphaviruses. The neurological disorder outbreak could not be linked to the alphaviruses tested. Our findings represent strong evidence that MAYV and all equine encephalitis alphaviruses circulated in the Pantanal.

  18. Study of measurement methods of ultrafine aerosols surface-area for characterizing occupational exposure

    International Nuclear Information System (INIS)

    This work aims at improving knowledge on ultrafine aerosols surface-area measurement. Indeed, the development of nano-technologies may lead to occupational exposure to airborne nano-structured particles, which involves a new prevention issue. There is currently no consensus concerning what parameter (mass, surface-area, number) should be measured. However, surface-area could be a relevant metric, since it leads to a satisfying correlation with biological effects when nano-structured particles are inhaled. Hence, an original theoretical work was performed to position the parameter of surface-area in relation to other aerosol characteristics. To investigate measurement techniques of nano-structured aerosols surface-area, the experimental facility CAIMAN (Characterization of Instruments for the Measurement of Aerosols of Nano-particles) was designed and built. Within CAIMAN, it is possible to produce nano-structured aerosols with varying and controlled properties (size, concentration, chemical nature, morphology, state-of-charge), stable and reproducible in time. The generated aerosols were used to experimentally characterize the response of the instruments in study (NSAM and AeroTrak 9000 TSI, LQ1-DC Matter Engineering). The response functions measured with monodisperse aerosols show a good agreement with the corresponding theoretical curves in a large size range, from 15 to 520 nm. Furthermore, hypotheses have been formulated to explain the reasonable biases observed when measuring poly-disperse aerosols. (author)

    A recent study reported neutralizing antibodies to West Nile virus (WNV) in horses from four ranches of southern Pantanal. To extend that study, a serosurvey for WNV and 11 Brazilian flaviviruses was conducted with 760 equines, 238 sheep and 61 caimans from 17 local cattle ranches. Among the tested equines, 32 were collected from a ranch where a neurologic disorder outbreak had been recently reported. The sera were initially screened by using a blocking ELISA and then titrated by 90% plaque-reduction neutralization test (PRNT90) for 12 flaviviruses. Employing the criterion of 4-fold greater titer, 78 (10.3%) equines were seropositive for Ilheus virus, 59 (7.8%) for Saint Louis encephalitis virus, 24 (3.2%) for WNV, two (0.3%) for Cacipacore virus and one (0.1%) for Rocio virus. No serological evidence was found linking the neurological disease that affected local equines to WNV. All caimans and sheep were negative by blocking ELISA for flaviviruses. There were no seropositive equines for Bussuquara, Iguape, Yellow fever and all four Dengue virus serotypes. The detection of WNV-seropositive equines in ten ranches and ILHV and SLEV-seropositive equines in fourteen ranches of two different sub-regions of Pantanal is strong evidence of widespread circulation of these flaviviruses in the region.

    Mesopelagic fishes play an important role in the transfer of organic material in the photic zone to depth although the trophodynamic partitioning amongst co-existing and presumably competing species is unclear. This study employs combined carbon and nitrogen stable isotope analyses (δ13C and δ15N) of the 18 most abundant western Mediterranean mesopelagic fishes to explore niche partitioning in this group. Sampling was conducted along the water column from the shelf and slope grounds of the Balearic Islands in two contrasting periods (late autumn and summer). Trophodynamics were explored at assemblage level and at inter- and intra-species resolutions respectively using Bayesian diet mixing models and size specific behaviour respectively. Seasonal δ13C differences in near basal particulate organic matter (POM) and zooplankton fractions were almost directly replicated in higher fauna suggesting strong isotopic coupling between mesopelagic fishes and planktonic production. Despite reliance on similar basal production, species were segregated by trophic position with a graduation from 2.9 for the small Gonostomatidae Cyclothone braueri to 4.0 for the Myctophidae Lobianchia dofleini. Mixing model data reflected basic trophic position estimates with higher contributions of small fish and zooplankton/POM in higher and lower trophic level species respectively. Species could be categorized as showing preference for i) mesozooplankton/POM as for C. braueri, (in the lower TrL), ii) euphausiids and fish prey as for L. dofleini and the near bottom Lampanyctus crocodilus (in the upper TrL) and iii) mesozooplankton/euphausiids as Ceratoscopelus maderensis, Lampanyctus pusillus or the migrating L. crocodilus. There was little evidence of size based inter-population trophodynamics, with size-isotope trends explained by co-varying lipid content.

  2. Quantification of induced resistance against Phytophthora species expressing GFP as a vital marker: beta-aminobutyric acid but not BTH protects potato and Arabidopsis from infection.

    SUMMARY Induced resistance was studied in the model pathosystem Arabidopsis-Phytophthora brassicae (formerly P. porri) in comparison with the agronomically important late blight disease of potato caused by Phytophthora infestans. For the quantification of disease progress, both Phytophthora species were transformed with the vector p34GFN carrying the selectable marker gene neomycine phosphotransferase (nptII) and the reporter gene green fluorescent protein (gfp). Eighty five per cent of the transformants of P. brassicae and P. infestans constitutively expressed GFP at high levels at all developmental stages both in vitro and in planta. Transformants with high GFP expression and normal in vitro growth and virulence were selected to quantify pathogen growth by measuring the in planta emitted GFP fluorescence. This non-destructive monitoring of the infection process was applied to analyse the efficacy of two chemical inducers of disease resistance, a functional SA-analogue, benzothiadiazole (BTH), and beta-aminobutyric acid (BABA) which is involved in priming mechanisms of unknown nature. BABA pre-treatment (300 microm) via soil drench applied 24 h before inoculation completely protected the susceptible Arabidopsis accession Landsberg erecta (Ler) from infection with P. brassicae. A similar treatment with BTH (330 microm) did not induce resistance. Spraying the susceptible potato cultivar Bintje with BABA (1 mm) 2 days before inoculation resulted in a phenocopy of the incompatible interaction shown by the resistant potato cultivar Matilda while BTH (1.5 mm) did not protect Bintje from severe infection. Thus, in both pathosystems, the mechanisms of induced resistance appeared to be similar, suggesting that the Arabidopsis-P. brassicae pathosystem is a promising model for the molecular analysis of induced resistance mechanisms of potato against the late blight disease.

    Huanglongbing (HLB) is currently the most economically devastating disease of citrus worldwide and no established cure is available. Defense inducing compounds are able to induce plant resistance effective against various pathogens. In this study the effects of various chemical inducers on HLB diseased citrus were evaluated in four groves (three with sweet orange and one with mandarin) in Florida (United States) for two to four consecutive growing seasons. Results have demonstrated that plant defense inducers including β-aminobutyric acid (BABA), 2,1,3-benzothiadiazole (BTH), and 2,6-dichloroisonicotinic acid (INA), individually or in combination, were effective in suppressing progress of HLB disease. Ascorbic acid (AA) and the nonmetabolizable glucose analog 2-deoxy-D-glucose (2-DDG) also exhibited positive control effects on HLB. After three or four applications for each season, the treatments AA (60 to 600 µM), BABA (0.2 to 1.0 mM), BTH (1.0 mM), INA (0.1 mM), 2-DDG (100 µM), BABA (1.0 mM) plus BTH (1.0 mM), BTH (1.0 mM) plus AA (600 µM), and BTH (1.0 mM) plus 2-DDG (100 µM) slowed down the population growth in planta of 'Candidatus Liberibacter asiaticus', the putative pathogen of HLB and reduced HLB disease severity by approximately 15 to 30% compared with the nontreated control, depending on the age and initial HLB severity of infected trees. These treatments also conferred positive effect on fruit yield and quality. Altogether, these findings indicate that plant defense inducers may be a useful strategy for the management of citrus HLB.

    Full Text Available Introduction Helicobacter pylori infection is associated with gastro-duodenal diseases. Genes related to pathogenicity have been described for H. pylori and some of them appear to be associated with more severe clinical outcomes of the infection. The present study investigates the role of cagE as a pathogenicity biomarker of H. pylori compare it to cagA, vacA, iceA and babA2 genes and correlate with endoscopic diagnoses. Methods Were collected biopsy samples of 144 dyspeptic patients at the Hospital of the Federal University of Rio Grande, Rio Grande do Sul, Brazil. After collection, the samples were sent for histological examination, DNA extraction and detection of all putative pathogenicity genes by PCR. Results Of the 144 patients undergoing endoscopy, 57 (39.6% presented H. pylori by histological examination and PCR by detection of the ureA gene. Based on the endoscopic diagnoses, 45.6% (26/57 of the patients had erosive gastritis, while 54.4% (31/57 had enanthematous gastritis. The genes cagA, cagE, vacAs1/m1, vacAs1/m2 and iceA1 were related to erosive gastritis, while the genes vacAs2/m2, iceA2 and babA2 were associated to enanthematous gastritis. We found a statistically significant association between the presence of cagE and the endoscopic diagnosis. However, we detect no statistically significant association between the endoscopic diagnosis and the presence of cagA, vacA, iceA and babA2, although a biological association has been suggested. Conclusions Thus, cagE could be a risk biomarker for gastric lesions and may contribute to a better evaluation of the H. pylori pathogenic potential and to the prognosis of infection evolution in the gastric mucosa.

    A study on the development of a transport system using the pinning effect of a superconducting bulk structure was undertaken and a model of a flywheel for electric power storage was manufactured by introducing a bearing applying the pinning effect to investigate the feasibility through its operation. The operation behavior of vertical transport combining the superconducting bulk structure and the electromagnetic coils reproduced the predictions of simulation. As for the electric power storage via flywheel, it was confirmed that the lighting duration of a indicating lamp was elongated from the ordinary interval, 1 min., to 4 min. (H. Baba)

    In French Guiana, a French overseas territory located in the South American northern coast, nearly 50% of Salmonella serotypes isolated from human infections belong to serotypes rarely encountered in metropolitan France. A reptilian source of contamination has been investigated. Between April and June 2011, in the area around Cayenne, 151 reptiles were collected: 38 lizards, 37 snakes, 32 turtles, 23 green iguanas and 21 caimans. Cloacal swab samples were collected and cultured. Isolated Salmonella strains were identified biochemically and serotyped. The overall carriage frequency of carriage was 23.2% (95% confidence interval: 16.7-30.4) with 23 serotyped strains. The frequency of Salmonella carriage was significantly higher for wild reptiles. Near two-thirds of the Salmonella serotypes isolated from reptiles were also isolated from patients in French Guiana. Our results highlight the risk associated with the handling and consumption of reptiles and their role in the spread of Salmonella in the environment.

    Full Text Available In workshops with four indigenous communities in the Embera-Katíos communal lands (resguardo , located in the upper San Jorge River Valley (Tres Playitas, Las Piedras, Boca San Cipriano, San Juan Medio, information about the wild fauna that they recognized inside their hunting grounds was collected. Mammals, reptiles, and birds, especially the Psittacidae family, are the vertebrates most used by the indigenous communities. No kind of use was found for amphibians. The consumption of reptiles such as Iguana iguana, Tupinambis teguixin, Caiman crocodylus fuscus, and Crocodylus acutus show them to be an important part of their culture. The indigenous communities associate environmental problems with habitat destruction due to the cultivation of illicit crops and forest clearing in the buffer zone around Paramillo National Park.

    Since several years, IPSN has conducted an effort in order to evaluate the release of radioactive iodine in case of hypothetical severe accident in a realistic manner. This source-term evaluation is performed with IODE code which is a module of the EXCADRE system of codes. This code is validated against: -analytical experiments: in these experiments, IPSN studies radiolytic effects and chemical processes in the sump, organic formation, mass transfer, effect of spray (CARAIDAS experiment), - the CAIMAN semi global experiment; this experiment will allow to study the phenomena linked to iodine behavior under representative containment geometry in the presence of painted surfaces and global irradiation, - the PHEBUS FP program. The paper consists to describe succinctly the current status of IODE and the various experiments for its validation. In case of hypothetical severe accident iodine can induce important perturbations of human organism. The effects are principally radiological, in particular on the thyroid. At short term, radioactive iodine is the most important contributor for the sanitary risk. It represents 55% of effective dose and 92% of thyroid dose at 10 km in case of controlled rejects with current assumptions. This is the reason why it must be actively studied. In France, the safety evaluations are performed with mechanistic codes or lumped parameter codes like EXCADRE which contains a module devoted to iodine studies: IODINE. The objective of the French experimental program on iodine is to understand and quantify important phenomena in order to put kinetic parameters in IODE module. The experiments can be classified in analytical experiments, the semi-global experiment CAIMAN which takes into account different phenomena studied in analytical experiments and the global experiment PHEBUS PF, not only devoted to iodine behavior study. In the following text we will present the needs of IODINE code and these different experiments. (author).

    Overfishing has affected the population abundance trends of many commercial fish species. In the Amazon, the fishery of a catfish commonly known as "mota" or "piracatinga" (Calophysus macropterus) has become an important economic activity in the region as this species has replaced a number of other overexploited great catfish species in the markets. Due to this high exploitation, ways in which to increase captures have been identified. One strategy is to use decomposing animal carcasses as bait. Such strategy has increased the hunting pressure on endangered species such as caimans and river dolphins. We investigated which catfish species are currently commercialized in Colombian fish markets using DNA barcoding, and measured mercury concentration in the tissues of fish molecularly identified as C. macropterus. We collected 86 fish samples in markets of four Colombian cities. Sixty-eight of these were identified molecularly as C.macropterus. The mercury concentration of 29 such samples was analyzed. Samples presented total Hg concentrations higher than the limit for human consumption established by the WHO (0.5 μg/g). These results are worrisome and suggest that (1) C. macropterus is a widely used fish species for human consumption in Colombia and (2) C. macropterus has high concentrations of total Hg, making its consumption a public health risk. Results presented here suggest that C. macropterus has replaced capaz in most Colombian markets. This fishery threatens wild species of river dolphins and caimans, and is also a public health risk given the high mercury levels we found in a subsample of these fishes. PMID:24419666

    Myctophids, gonostomatids and sternoptychids are the most abundant teleosteans worldwide and constitute an important assemblage of the mesopelagic ecosystem, functioning as vehicles of energy and matter through trophic webs. This study concentrates on the trophic ecology of the most abundant mesopelagic fishes of the western Mediterranean (WM) based on stomach content analysis. The myctophids (in this study: Benthosema glaciale, Ceratoscopelus maderensis, Lobianchia dofleini, Myctophum punctatum, Hygophum benoiti, Hygophum hygomii, Lampanyctus crocodilus, Lampanyctus pusillus and Notoscopelus elongatus) perform extensive diel migrations across the water column, between the surface to as deep as 1000 m, interacting with plankton and micronekton at multiple depths, and generally feeding in the epipelagic layers at night. In contrast, the gonostomatids Cyclothone braueri, Cyclothone pygmaea, and the sternoptychid Argyropelecus hemigymnus remain below epipelagic layers, feeding at different times throughout the day and night. The diet composition, trophic niche breadth and prey selectivity of 11 of these fish species were determined for juvenile and adult individuals from two surveys performed in December 2009 and July 2010 in the western Mediterranean Sea. The number of prey items varied among species, e.g. Myctophum punctatum was the species with the highest feeding intensity, reaching ca. 700 prey items in a stomach, whereas the mean number of prey in Cyclothone braueri was low (usually 1 or 2 prey per stomach). A dietary shift towards larger prey was evident from juveniles to the largest and oldest adult individuals, despite trophic niche breadths did not increase with body length for any of these mesopelagic species. The diets of the small gonostomatids, sternoptychid and early juveniles of myctophids were dominated by non-calanoid copepods, ostracods, and other small zooplankton, whereas medium-sized myctophids, e.g. L. dofleini or H. benoiti, preyed mainly on

    2014-01-01

    Full Text Available Background: The click and tone-evoked auditory brainstem responses are widely used in clinical practice due to their consistency and predictability. More recently, the speech-evoked responses have been used to evaluate subcortical processing of complex signals, not revealed by responses to clicks and tones. Aims: Disyllable stimuli corresponding to familiar words can induce a pattern of voltage fluctuations in the brain stem resulting in a familiar waveform, and they can yield better information about brain stem nuclei along the ascending central auditory pathway. Materials and Methods: We describe a new method with the use of the disyllable word "baba" corresponding to English "daddy" that is commonly used in many other ethnic languages spanning from West Africa to the Eastern Mediterranean all the way to the East Asia. Results: This method was applied in 20 young adults institutionally diagnosed as dyslexic (10 subjects or light dyslexic (10 subjects who were matched with 20 sex, age, education, hearing sensitivity, and IQ-matched normal subjects. The absolute peak latencies of the negative wave C and the interpeak latencies of A-C elicited by verbal stimuli "baba" were found to be significantly increased in the dyslexic group in comparison with the control group. Conclusions: The method is easy and helpful to diagnose abnormalities affecting the auditory pathway, to identify subjects with early perception and cortical representation abnormalities, and to apply the suitable therapeutic and rehabilitation management.

    Full Text Available Ecological niche modelling was used to predict the potential geographical distribution of Rhodnius nasutus Stål and Rhodnius neglectus Lent, in Brazil and to investigate the niche divergence between these morphologically similar triatomine species. The distribution of R. neglectus covered mainly the cerrado of Central Brazil, but the prediction maps also revealed its occurrence in transitional areas within the caatinga, Pantanal and Amazon biomes. The potential distribution of R. nasutus covered the Northeastern Region of Brazil in the semi-arid caatinga and the Maranhão babaçu forests. Clear ecological niche differences between these species were observed. R. nasutus occurred more in warmer and drier areas than R. neglectus. In the principal component analysis PC1 was correlated with altitude and temperature (mainly temperature in the coldest and driest months and PC2 with vegetation index and precipitation. The prediction maps support potential areas of co-occurrence for these species in the Maranhão babaçu forests and in caatinga/cerrado transitional areas, mainly in state of Piaui. Entomologists engaged in Chagas disease vector surveillance should be aware that R. neglectus and R. nasutus can occur in the same localities of Northeastern Brazil. Thus, the identification of bugs in these areas should be improved by applying morphometrical and/or molecular methods.

    This study investigated whether a short intensive psychophysical auditory training program is associated with speech perception benefits and changes in cortical auditory evoked potentials (CAEPs) in adult cochlear implant (CI) users. Ten adult implant recipients trained approximately 7 hours on psychophysical tasks (Gap-in-Noise Detection, Frequency Discrimination, Spectral Rippled Noise [SRN], Iterated Rippled Noise, Temporal Modulation). Speech performance was assessed before and after training using Lexical Neighborhood Test (LNT) words in quiet and in eight-speaker babble. CAEPs evoked by a natural speech stimulus /baba/ with varying syllable stress were assessed pre- and post-training, in quiet and in noise. SRN psychophysical thresholds showed a significant improvement (78% on average) over the training period, but performance on other psychophysical tasks did not change. LNT scores in noise improved significantly post-training by 11% on average compared with three pretraining baseline measures. N1P2 amplitude changed post-training for /baba/ in quiet (p = 0.005, visit 3 pretraining versus visit 4 post-training). CAEP changes did not correlate with behavioral measures. CI recipients' clinical records indicated a plateau in speech perception performance prior to participation in the study. A short period of intensive psychophysical training produced small but significant gains in speech perception in noise and spectral discrimination ability. There remain questions about the most appropriate type of training and the duration or dosage of training that provides the most robust outcomes for adults with CIs. PMID:27587925

    In order to avoid negative wave resistance (which is physically incomprehensible) generated in calculating wave resistance by using the Rankine source method, a proposal was made on a wave resistance calculation method using the Kochin function which describes behavior of speed potential in regions far apart from a hull. The Baba`s condition was used as a free surface condition for the speed potential which expresses wave motions around a hull. This has allowed a new Kochin function which uses as unknown the speed potential on the hull surface and the free surface near the hull to be defined and combined with the Rankine source method. A comparison was made between the calculated values for wave resistance, hull subsidence and trim change of an ore transporting vessel (SR107 type of ship) in a fully loaded condition and the result of water tank tests. The wave resistance values derived from pressure integration have all become negative when the Froude number is from 0.1 to 0.2, while no negative resistance has appeared in the calculations by using the Kochin function, but the result has agreed with that of the water tank tests. Accuracy of the calculations at low speeds was improved. The trim change in the calculations was slightly smaller than that in the water tank tests. The subsidence showed a good agreement. 7 refs., 1 fig.

O experimento in vitro foi realizado utilizando-se cinco concentrações (0,2; 0,4; 0,6; 0,8 e 1,0% dos dez óleos misturados ao meio de cultura BDA. As variáveis analisadas foram a taxa de crescimento micelial e o índice de velocidade de crescimento micelial (IVCM. O ensaio em pós-colheita foi feito com imersão dos frutos de pimenta por 5 minutos, nos mesmos óleos utilizados no experimento anterior, usando-se a maior concentração. O fungo C. gloeosporioides foi inoculado, através de ferimento, logo após a imersão dos frutos. As avaliações foram realizadas diariamente através de medição do diâmetro das colônias e das lesões, tomando-se duas medições em sentidos diametralmente opostos. Pode-se observar que no experimento in vitro todos os óleos, com exceção dos óleos de babaçu, semente de uva e amêndoa, tiveram excelentes resultados inibindo o crescimento do fungo. No resultado obtido em pós-colheita foi observado que apenas o óleo de babaçu não foi eficiente em reduzir o desenvolvimento da lesão de antracnose. Dados relevantes foram observados para os óleos de semente de uva e amêndoa, que não apresentaram efeito direto sobre o fungo in vitro, porém no tratamento pós-colheita apresentaram bons resultados, reduzindo a lesão causada por C. gloeosporioides, sugerindo assim que estes óleos possam ser utilizados como indutores de resistência em frutos

    Samples were collected from Miocene tuffs widely distributed on Takasaki area, Iwatono Hill, and Karasuyama area in the Kanto district. Zircon crystals were separated from seven samples in them, and the crystal morphology was investigated. Seven samples can be divided into two groups, one is characterized by zircon crystals of the 100 dominant type and short prismatic, and Kt-1 (Kitamura Tuff), I-8 (Shogunzawa Tuff) and Og-1 belong to this group. The other group is characterized by zircon crystals of the intermediate type and prismatic, and Bb-1 (Baba Tuff), I-12 (Okuda Tuff), Og-25 and Og-52 (Iwako Tuff Member) belong to this group. Other data, including micro fossils and radiometric ages, support the above division. The quantitative description is reliable as one of the standard criteria for the geologic correlation of tuff layers over a wide area. 33 refs., 4 figs., 1 tab.

    Non-stationary diffusion experiments were carried out using Na-type montmorillonite and apparent diffusion coefficients were obtained for Cs{sup +}, Na{sup +}, Sr{sup 2+}, and Cl{sup -}. Deduced activation energies proved to reveal complex dry-density dependencies, suggesting change of the diffusion process with increase of the dry density. In order to study the corrosion behavior of iron in pressurized clay, the diffusion rate of iron in bentonite and apparent diffusion coefficient of the corrosion products were determined using radioactive iron foil sandwiched between two bentonite blocks. The result was reproduced well by the diffusion equation with diffusion origins of constant concentration and the degree of oxidation of iron pyrites was found to substantially affect the corrosion reaction and migration behavior of corrosion products. Furthermore, a diffusion experiment and experiment of selective sequential extraction were carried out with {sup 237}Np in order to collect information on the adsorption condition of Np. (H. Baba)

    Adsorption-desorption tests for Fe{sup 2+} ions versus Na-type smectite were carried out in the solution under the controlled atmosphere (O{sub 2} < 0.1 ppm, CO{sub 2} < 2 ppm) in order to elucidate the interaction between bentonite and iron containers for underground waste disposal. Smectite after the adsorption test was subjected to the X-ray diffraction and X-ray photoelectron spectroscopy to study the Fe{sup 2+} adsorption site. As a result, the interaction between Fe{sup 2+} and smectite was shown to be reversible ion exchange between Na{sup +} and Fe{sup 2+} in the interlayer space of smectite. The ion exchange distribution coefficient was found to be log K = 1.08 {+-} 0.07 and 0.66 {+-} 0.19 for the ionic strength of 0.05 and 0.0016, respectively. (H. Baba)

    Thermodynamic properties of buffer materials were measured for putting in order thermodynamic constants to be used in the near-field thermal analysis. The thermal diffusivity and thermal conductivity were measured as functions of the water content and temperature to deduce the specific heat. The thermal conductivity and specific heat varied significantly as the water content changed. Obtained values of the specific heat agreed well the expected values calculated based on the constituents of the buffer material. Temperature dependence of the thermodynamic constants was found small below 90degC. From the findings, the thermal conductivity and specific heat of the buffer material were formulated as functions of the water content. Thermodynamic study of powdery bentonite was carried out as well with a purpose of use for filling apertures in the artificial barrier. (H. Baba)

    A robotic approach for thyroid surgery was developed to overcome the limitations of endoscopic thyroidectomy and provide many technical advantages. This approach facilitates the surgeon’s control through a magnified three-dimensional view, decreased tremor, and freedom of motion with articulated instruments. Robotic thyroidectomy is safe and technically feasible in patients with well-differentiated, low-risk thyroid cancer. Furthermore, robotic thyroidectomy may become a good surgical alternative option for patients with more advanced thyroid cancer. Our modified bilateral axillo-breast approach (BABA) for central and lateral cervical neck lymph node (LN) dissection has yielded excellent surgical outcomes as an open procedure. The incorporation of robotics in thyroid cancer surgery will continue to evolve, and the surgical indications for robotic thyroidectomy will continue to expand. Further analyses that include long-term outcomes and randomized comparative trials remain important. PMID:27294043

    Full Text Available In order to prolong the life of the old buildings in the country through building conservation practices, there is a tendency by the government to acquire and reuse Malaysian leadership figures’ residential buildings as memorials. However, it raises the question of whether there is any adaptive reuse guidelines to reuse historic residential buildings in Malaysia as national memorials in maintaining those buildings as an exhibition space on the history of their leadership. The absence of guidelines raises questions about how to implement the process accordingly. The objective of this research is to find the best formula for reusing historic residential buildings as national memorials based on that issue by reviewing and identify the principles of adaptive reuse practices of historic residential buildings as national memorials that implemented in Malaysia. The case studies were conducted on three samples of historic residential buildings that reused as national memorials and those buildings were selected based on a list of the study population, which are Rumah Kelahiran Tun Dr. Mahathir Mohamad (The Birthplace of Tun Dr. Mahathir Mohamad, Rumah Merdeka (Freedom House and Memorial Tun Abdul Ghafar Baba (The Tun Abdul Ghafar Baba Memorial. The sample may be determined by the sampling method and evaluated using the checklist provided. Based on the results of the case studies that were analyzed and discussed, it can be concluded that aspects of building code (local requirements as well as environmental and conservation requirements are not met in implementing adaptive reuse process on historic residential buildings to national memorials which needs suggestions for improvement.

  13. Antiadhesive properties of Abelmoschus esculentus (Okra immature fruit extract against Helicobacter pylori adhesion.

    Directory of Open Access Journals (Sweden)

    Jutta Messing

    Full Text Available BACKGROUND: Traditional Asian and African medicine use immature okra fruits (Abelmoschus esculentus as mucilaginous food to combat gastritis. Its effectiveness is due to polysaccharides that inhibit the adhesion of Helicobacter pylori to stomach tissue. The present study investigates the antiadhesive effect in mechanistic detail. METHODOLOGY: A standardized aqueous fresh extract (Okra FE from immature okra fruits was used for a quantitative in vitro adhesion assay with FITC-labled H. pylori J99, 2 clinical isolates, AGS cells, and fluorescence-activated cell sorting. Bacterial adhesins affected by FE were pinpointed using a dot-blot overlay assay with immobilized Lewis(b, sialyl-Lewis(a, H-1, laminin, and fibronectin. (125I-radiolabeled Okra FE polymer served for binding studies to different H. pylori strains and interaction experiments with BabA and SabA. Iron nanoparticles with different coatings were used to investigate the influence of the charge-dependence of an interaction on the H. pylori surface. PRINCIPAL FINDINGS: Okra FE dose-dependently (0.2 to 2 mg/mL inhibited H. pylori binding to AGS cells. FE inhibited the adhesive binding of membrane proteins BabA, SabA, and HpA to its specific ligands. Radiolabeled compounds from FE bound non-specifically to different strains of H. pylori, as well as to BabA/SabA deficient mutants, indicating an interaction with a still-unknown membrane structure in the vicinity of the adhesins. The binding depended on the charge of the inhibitors. Okra FE did not lead to subsequent feedback regulation or increased expression of adhesins or virulence factors. CONCLUSION: Non-specific interactions between high molecular compounds from okra fruits and the H. pylori surface lead to strong antiadhesive effects.

    Full Text Available Immune-stimulated plants are able to respond more rapidly and adequately to various biotic stresses allowing them to efficiently combat an infection. During the priming phase, plant are stimulated in absence of a challenge, and can accumulate and store conjugates or precursors of molecules as well as other compounds that play a role in defense. These molecules can be released during the defensive phase following stress. These metabolites can also participate in the first stages of the stress perception. Here, we report the metabolic changes occuring in primed plants during the priming phase. β-aminobutyric acid (BABA causes a boost of the primary metabolism through the tricarboxylic acids (TCA such as citrate, fumarate, (S-malate and 2-oxoglutarate, and the potentiation of phenylpropanoid biosynthesis and the octodecanoic pathway. On the contrary, Pseudomonas syringae pv tomato (PstAvrRpt2 represses the same pathways. Both systems used to prime plants share some common signals like the changes in the synthesis of amino acids and the production of SA and its glycosides, as well as IAA. Interestingly, a product of the purine catabolism, xanthosine, was found to accumulate following both BABA- and PstAvrRpt2-treatement. The compounds that are strongly affected in this stage are called priming compounds, since their effect on the metabolism of the plant is to induce the production of primed compounds that will help to combat the stress. At the same time, additional identified metabolites suggest the possible defense pathways that plants are using to get ready for the battle.

    Helicobacter pylori causes various diseases such as chronic gastritis, peptic ulcer and gastric cancer. While majority of the people infected with H. pylori is asymptomatic, 15-20 % of them develop such diseases. The main factors, which determine the development of H. pylori related diseases might be bacterial virulence, host genetic and environmental factors.The aim of this study was to reveal the factors that play a role in the disease development in patients with reflux esophagitis and peptic ulcer, infected with Helicobacter pylori. Environmental factors such as medical agents, smoking and body mass index were evaluated. The factors specific to bacteria such as vacA, CagA, babA and iceA virulence genotypes and the host factors such as IL-1, IL-2, IL-4, IL-6, IL-10, IL-12, interferon-γ, TNF-α, ve TGF-β1 gene polymorphisms were compared between the two groups.H. pylori infected twenty five patients with reflux esophagitis and peptic ulcer were enrolled in the study. There was no statistical difference between the two groups regarding environmental factors. IL-2 -330T +166T (p=0.037) and IL10 -1082A; -819C (p=0.049) gene polymorphisms were significantly more common in the group of patients with peptic ulcer compared to the group with reflux esophagitis. In both groups of patients, either with reflux esophagitis or peptic ulcer, multiple H. pylori virulence genotypes (cagA, vacA, babA) (mean values 74 %, 78 %, 54 % respectively) were observed.In this study, we revealed that cytokine gene polymorphisms may play a role in the development peptic ulcer while H. pylori virulence genotypes seem to be crucial for the development of associated diseases (Tab. 4, Ref. 51).

    What makes for sustainable individual and organizational performance? Employees who are thriving-not just satisfied and productive but also engaged in creating the future. The authors found that people who fit this description demonstrated 16% better overall performance, 125% less burnout, 32% more commitment to the organization, and 46% more job satisfaction than their peers. Thriving has two components: vitality, or the sense of being alive and excited, and learning, or the growth that comes from gaining knowledge and skills. Some people naturally build vitality and learning into their jobs, but most employees are influenced by their environment. Four mechanisms, none of which requires heroic effort or major resources, create the conditions for thriving: providing decision-making discretion, sharing information about the organization and its strategy, minimizing incivility, and offering performance feedback. Organizations such as Alaska Airlines, Zingerman's, Quicken Loans, and Caiman Consulting have found that helping people grow and remain energized at work is valiant on its own merits-but it can also boost performance in a sustainable way.

    2002-01-01

    Full Text Available In Central Amazon, Brazil, the tabanid Phorcotabanus cinereus (Wiedemann was recorded attacking the native duck Cairina moschata (Linnaeus (Anseriformes, Anatidae. The flight and behavior of the tabanid during the attacks and the host's defenses were videotaped and analyzed in slow motion. The tabanid was recorded flying rapidly around the heads of the ducks before landing. Landing always took place on the beak, and then the tabanid walked to the fleshy caruncle on the basal part of the beak to bite and feed. Firstly the duck defends itself through lateral harsh head movements, and then, when it is being bitten, it defends itself by rubbing its head on the body, or dipping the head into water, when swimming. If disturbed, the fly resumed the same pattern of flight as before and would generally try to land again on the same host and bite in the same place. This feeding activity was observed predominantly between 9:30 am and 4:30 pm and always in open areas, near aquatic environments, from June 1996 to January 1997, the dry season in Central Amazon. To test the attractiveness of other animals to P. cinereus, mammals, caimans and domestic and wild birds were placed in suitable habitat and the response of P. cinereus observed. P. cinereus did not attack these animals, suggesting that this species has a preference for ducks, which are plentiful in the region.

    The fishery for Calophysus macropterus, an Amazonian necrophagous catfish, is highly detrimental to river dolphins and caimans, which are deliberately killed for use as bait. In the Brazilian Amazon, this fishery has increased over the last decade, in spite of the rejection of scavenger fishes by Brazilian consumers. It was suspected that C. macropterus fillets were being sold in Brazilian markets, disguised as a fictitious fish (the "douradinha"). We collected 62 fillets from "douradinha" and other suspiciously named fish from 4 fish-processing plants sold at 6 markets in Manaus, in the Brazilian Amazon, and sequenced the cytochrome b gene to identify fillets to species. Sixty percent of fillets labeled "douradinha" or with other deceptive names were actually C. macropterus. Six other fish species of low commercial value were also found. The presence of dolphin tissue in the stomach contents of C. macropterus was confirmed by mtDNA control region sequencing. Our results formed the scientific basis for a moratorium on the fishing and fraudulent selling of C. macropterus, issued by the Brazilian Ministries of the Environment and Fisheries. Exposure of this fraud via the mass media can help end the illegal use of dolphins as bait in Brazil.

    Heteroplasmic tandem repeats in the mitochondrial control region have been documented in a wide variety of vertebrate species. We have examined the control region from 11 species in the family Crocodylidae and identified two different types of heteroplasmic repetitive sequences in the conserved sequence block (CSB) domain-an extensive poly-A tract that appears to be involved in the formation of secondary structure and a series of tandem repeats located downstream ranging from approximately 50 to approximately 80 bp in length. We describe this portion of the crocodylian control region in detail and focus on members of the family Crocodylidae. We then address the origins of the tandemly repeated sequences in this family and suggest hypotheses to explain possible mechanisms of expansion/contraction of the sequences. We have also examined control region sequences from Alligator and Caiman and offer hypotheses for the origin of tandem repeats found in those taxa. Finally, we present a brief analysis of intraindividual and interindividual haplotype variation by examining representatives of Morelet's crocodile (Crocodylus moreletii). PMID:12716979

    This report describes the results of the second phase of International Standard Problem (ISP) 41, an iodine behaviour code comparison exercise. The first phase of the study, which was based on a simple Radioiodine Test Facility (RTF) experiment, demonstrated that all of the iodine behaviour codes had the capability to reproduce iodine behaviour for a narrow range of conditions (single temperature, no organic impurities, controlled pH steps). The current phase, a parametric study, was designed to evaluate the sensitivity of iodine behaviour codes to boundary conditions such as pH, dose rate, temperature and initial I{sup -} concentration. The codes used in this exercise were IODE(IPSN), IODE(NRIR), IMPAIR(GRS), INSPECT(AEAT), IMOD(AECL) and LIRIC(AECL). The parametric study described in this report identified several areas of discrepancy between the various codes. In general, the codes agree regarding qualitative trends, but their predictions regarding the actual amount of volatile iodine varied considerably. The largest source of the discrepancies between code predictions appears to be their different approaches to modelling the formation and destruction of organic iodides. A recommendation arising from this exercise is that an additional code comparison exercise be performed on organic iodide formation, against data obtained front intermediate-scale studies (two RTF (AECL, Canada) and two CAIMAN facility, (IPSN, France) experiments have been chosen). This comparison will allow each of the code users to realistically evaluate and improve the organic iodide behaviour sub-models within their codes. (author)

    The 16746-neucleotide (nt) sequence of mitochondrial DNA (mtDNA) of Chinese alligator, Alligator sinensis, was determined using the Long-PCR and primer walking methods. As is typical in vertebrates, the mtDNA encodes 13 proteins, 2 rRNA, 22 tRNA genes, and a noncoding control region. The composition of bases is respectively 29.43% A, 24.59% T, 14.86% G, 31.12% C. The gene arrangement differs from the common vertebrate gene arrangement, but is similar to that of other crocodiles. DNA sequence data from 12S rRNA, 16S rRNA, protein-coding genes and combined sequence data were used to reconstruct the phylogeny of reptiles with the MP and ML methods. With this large data set and an appropriate range of outgroup taxa,the authors demonstrate that Chinese alligator is most closely related to American alligator among three crocodilian species, which suppors the traditional viewpoint. According to the branch lengths of ML tree from the combined data set,the primary divergence between Alligator and Caiman genus was dated at about 74.9 Ma, the split between Chinese alligator and American alligator was dated at 50.9 Ma.

    Estrogen receptors (ERs) play an important role in estrogen function. However, it is well known that there are species differences in amino acid sequences of the ligand binding domains. Here, we report on the analysis of species differences in ER-dependent transactivation with some chemicals using reporter gene assays. Full-length ER cDNAs from human, rat, chicken, alligator (Caiman), whiptail lizard, African clawed frog and rainbow trout were prepared from hepatic mRNA by the RT-PCR method and inserted into expression plasmids. Both expression and reporter plasmids were transiently transfected into HeLa cells, and then the estrogenic effects of chemicals were analyzed in terms of induction of luciferase activity. No species differences in transactivation were found among human, rat, chicken, alligator, whiptail lizard and African clawed frog ERs. However, thermo-dependent alteration in susceptibility to 17-beta-estradiol was observed with the rainbow trout ER because of thermo-dependence of estrogen binding. PMID:12648522

    Individuals who live and work in the Southeastern coastal range of the 3 US crocodilian carnivores, American alligators, American crocodiles, and caiman, understand the risks of reptile-human encounters. Individuals who live in other parts of the country maybe exposed through contact with exotic pets at private homes, small menageries, or petting zoos or from escaped or abandoned animals. During these encounters, individuals may be severely injured.Emergency medical services, law enforcement, and animal welfare workers in nonhabitat areas are usually not trained in the handling and safe removal of injured individuals from the scene when the reptile is present. The emergency management of large crocodilian injuries is similar to that of other major trauma; however, providers also must take into consideration the significant crush component potentially inflicted by the tremendous bite power and shaking inflicting during attacks by these large reptiles, appropriate antibiotic coverage for less common organisms that inhabit their mouths, and management of possible psychological distress, including posttraumatic stress disorder produced by such an unusual attack. Emergency physicians should support the development of a readily available national database of scientifically collect information on attacks to inform appropriate care and support efforts to explore responsible measures that the USDA Animal and Plant Health Inspection Service and other appropriate local, state, and federal agencies can take to ensure ethical and biologically sustainable management of our large reptiles, which also helps to ensure the safety of the public.

The results of aerobic mesophilic bacteria ranged between <1.0 a 3.6 log CFU/g, being the biggest counting in ostrich meat. The meat that had the biggest counting of micro-organisms psychrotrophs was also the ostrich, but even so, it was not considered high, ranging between 2.3 and 2.7 log CFU/g. There were no counting for coliforms and E. coli on wild boar and alligator meats (except sample 4 of wild boar meat that had a count of 1.0 log CFU/g of coliforms but, all ostrich meat had count, ranged between 1.3 a 2.7 log CFU/g. In generally, the literature shows that wild animals meats have higher protein values (19.5 to 22.8% CP than domestic animals, this values agree with the values found in this work, 19.9 to 29.9% CP.

    Microsatellites are genomic sequences comprised of tandem repeats of short nucleotide motifs widely used as molecular markers in population genetics. FullSSR is a new bioinformatic tool for microsatellite (SSR) loci detection and primer design using genomic data from NGS assay. The software was tested with 2000 sequences of Oryza sativa shotgun sequencing project from the National Center of Biotechnology Information Trace Archive and with partial genome sequencing with ROCHE 454® from Caiman latirostris, Salvator merianae, Aegla platensis, and Zilchiopsis collastinensis. FullSSR performance was compared against other similar SSR search programs. The results of the use of this kind of approach depend on the parameters set by the user. In addition, results can be affected by the analyzed sequences because of differences among the genomes. FullSSR simplifies the detection of SSRs and primer design on a big data set. The command line interface of FullSSR was intended to be used as part of genomic analysis tools pipeline; however, it can be used as a stand-alone program because the results are easily interpreted for a nonexpert user.

    Transferrins play a major role in iron homeostasis and metabolism. In vertebrates, these proteins are synthesised in the liver and dispersed within the organism by the bloodstream. In oviparous vertebrates additional expression is observed in the oviduct and the synthesised protein is deposited in egg white as ovotransferrin. Most research on ovotransferrin has been performed on the chicken protein. There is a limited amount of information on other bird transferrins, and until our previous paper on red-eared turtle protein there was no data on the isolation, sequencing and biochemical properties of reptilian ovotransferrins. Recently our laboratory deposited ten new sequences of reptilian transferrins in the EMBL database. A comparative analysis of these sequences indicates a possibility of different mechanisms of iron release among crocodile and snake transferrin. In the present paper we follow with the purification and analysis of the basic biochemical properties of two crocodile (Crocodilus niloticus, C. rhombifer) and one snake (Python molurus bivittatus) ovotransferrins. The proteins were purified by anion exchange and hydrophobic chromatography, and their N-terminal amino-acid sequences, molecular mass and isoelectric points were determined. All three proteins are glycosylated and their N-glycan chromatographic profiles show the largest contribution of neutral oligosaccharides in crocodile and disialylated glycans in python ovotransferrin. The absorption spectra of iron-saturated transferrins were analysed. Iron release from these proteins is pH-dependent, showing a biphasic character in crocodile ovotransferrins and a monophasic type in the python protein. The reason for the different types of iron release is discussed.

Despite its widespread use in both pharmaceutical and food industries, the literature has neither scientific studies about microbial contamination for these products nor about legal information expressed on label. The aim of this study was to evaluate the level of microbiological contamination in babassu mesocarp sold in commercial establishments in Teresina-PI/Brazil besides the conformity of label information according to the rules of Brazilian Sanitary Surveillance Agency (ANVISA. Ten samples of babassu mesocarp powder sold in the region were selected for study. Determination of heterotrophic microorganisms was carried out using the seeding technique of Plate Count Agar (CFU g-1. It was used Sabouraud Dextrose Agar medium for cultivation of fungi. For the analysis of label information, the resolutions (RDC, 259 of September 20, 2002, and 360 of December 23, 2003, beyond the law 10,674 of May 16, 2003 were used.

Nesse trabalho, investigou-se a aplicação de novos sistemas de reagentes para flotar o minério de zinco com willemita, em etapas de depressão de gangas, dispersão, sulfetização e flotação do zinco. Os testes de flotação, usando emulsão de amina com óleos vegetais e diesel, mostraram que a amina emulsificada apresentou um desempenho na flotação superior à amina não emulsificada, além de permitir uma redução significativa de sulfeto de sódio. Dos óleos vegetais estudados destacaram-se a mamona e o coco-babaçu, porém os resultados de recuperação foram inferiores ao óleo diesel.Several approaches to the flotation of oxidized zinc ores were already studied, and according to most of the researchers, the cationic flotation with high concentrations of sodium sulfide, using primary amine as collector, has been the most appropriate option to concentrate this type of ore. In this work, the application of innovative systems of reagents to float willemite was investigated, including the stages of gangue depression, dispersion, sulfidization and zinc flotation. The flotation tests using amine emulsion with vegetable oils and diesel oil showed that the amine emulsion yielded a better flotation performance than that of amine without emulsion, besides allowing a significant reduction of sodium sulfide dosage. Among the vegetable oils studied castor and babaçu coconut oils yielded reasonable results, despite not leading to the same zinc recovery levels achieved with diesel oil.

Only one patient was colonised/infected by two ancestrally unrelated strains. Among the 126 isolates, a significant association among cagPAI genotypes, oipA status and vacA alleles was indicated. Complete cagPAI, oipA "on", and vacA s1-m1 variants were significantly found in patients with PUD, without intra-host variations. Isolates from 7/14 patients with CG lacked babA in all chromosomal loci. In contrast, isolates from all or several biopsies of PUD patients carried babA, but in one patient only, the isolates showed positive Lewis b (Leb) binding assay. Considering cagPAI, vacA, oipA, bab genotypes, intra-host variation was also significantly higher in patients with CG. Conversely, a similarly high intra-host variation in almost PZ genes was observed in isolates from patients with CG and PUD. In conclusion, the lowest intra-host variation in cagPAI, oipA, vacA, and bab genes found in patients with PUD suggests the selection of a particular variant along the bacteria-host environment interplay during ulceration development. However, the predominance of this variant may be a refletion of the multifactorial etiology of the disease rather than the cause, as it was also found in patients with CG.

    The phylogenetic relationships amongst the Arminidae were analysed based upon morphological characters of 58 presently described species or nudibranchs, including 35 previously described Arminidae and 20 new species of Dermatobranchus. From the literature review and anatomical examinations, 43 characters were considered for 78 taxa. These characters were polarized using Berthella canariensis as the outgroup taxon and the type species of several other genera identified from recent publications. The resulting phylogeny supports the monophyly of Arminidae, Dermatobranchus, Doridina, and Proctonotidae. The paraphyly of the Arminina is further demonstrated in this study. Two previously described, but poorly known, species of Indo-Pacific Armina are redescribed, Armina magna Baba, 1955 and Armina paucifoliata Baba, 1955. The anatomy and taxonomic status of nine previously described species of Dermatobranchus were examined in this study. The anatomy of Dermatobranchus pustulosus (van Hasselt, 1824) has been overlooked since Bergh (1888) illustrated the radula of van Hasselt's specimen. It is redescribed and its range is extended to several new localities in the western Pacific. Dermatobranchus pulcherrimus Miller & Willan, 1986 is considered here as a new synonym of Dermatobranchus rubidus (Gould, 1852). The following 20 species of Dermatobranchus are new and are described in the present paper: Dermatobranchus albineus sp. nov., Dermatobranchus arminus sp. nov., Dermatobranchus caesitius sp. nov., Dermatobranchus caeruleomaculatus sp. nov., Dermatobranchus cymatilis sp. nov., Dermatobranchus dendonephthyphagus sp. nov., Dermatobranchus diagonalis sp. nov., Dermatobranchus earlei sp. nov., Dermatobranchus fasciatus sp. nov., Dermatobranchus funiculus sp. nov., Dermatobranchus kalyptos sp. nov., Dermatobranchus kokonas sp. nov., Dermatobranchus leoni sp. nov., Dermatobranchus microphallus sp. nov., Dermatobranchus oculus sp. nov., Dermatobranchus phyllodes sp. nov

In the present study, we designed a new PCR-based strategy to investigate the intactness of cagPAI in Iranian patients using highly specific primer sets spanning the cagPAI region. The possible relationship between the cagPAI status of the strains and clinical outcomes was also determined. We also characterized virulence genotypes (cagL, cagA, vacA, babA2 and sabA) and variants of CagA EPIYA motifs in these strains. H. pylori was detected in 61 out of 126 patients with various gastroduodenal diseases. The cagL, cagA, vacA s1m1, vacA s1m2, vacA s2m2, babA2, and sabA genotypes were detected in 96.7%, 85.2%, 29.5%, 45.9%, 24.6%, 96.7%, and 83.6% of the strains, respectively. Among the 52 cagA-positive strains, EPIYA motifs ABC, ABCC, ABCCC, and mixed types were orderly detected in the 39, 7, 1, and 5 strains. The cagPAI positivity included both intact and partially deleted, with the overall frequencies of 70.5% and 26.2%, respectively. The majority of the strains from patients with PUD (87.5%), gastric erosion (83.3%) and cancer (80%) presented an intact cagPAI, while a lower frequency of cagPAI intactness was detected in gastritis patients (61.1%). However, no significant relationship was found between the possession of intact cagPAI and clinical outcomes. Furthermore, we found that cagA and vacA s1m1 genotypes were significantly correlated with intact cagPAI (P=0.015 and P=0.012). A significant correlation was also found between EPIYA-ABC and intact cagPAI (P=0.010). The proposed PCR-based scheme was found to be useful for determining the intactness of cagPAI. Our findings also indicate that the cagPAI appears to be intact and rather conserved in majority of Iranian strains. Finally, our study proposed that H. pylori strains with partially deleted cagPAI were less likely to cause severe diseases

Para tanto, constrói a metáfora das metamorfoses do olhar etnográfico, o que permite detectar momentos importantes da recepção e reprodução, em países periféricos como o Brasil, desse saber plasmado nos países centrais nos dias do colonialismo. Em seguida passa em revista as idéias de teóricos do pensamento pós-colonial e dos estudos subalternos, como Edward Said, Gayatri Spivak e Homi Bhabha. Num terceiro momento, discute as possibilidades de uma etnografia pós-colonial, voltada para a narração das vozes subalternas, o que aproxima a Antropologia da Literatura Comparada. Finalmente, ilustra essas discussões com a apresentação de uma narrativa extraordinária de uma quebradeira de côco de babaçu do Maranhão, texto que erijo como emblemático da condição contemporânea de desenraizamento e perplexidade a que estamos submetidos, tanto os nossos supostos nativos como os etnógrafos e intelectuais dos países periféricos.The essay presents, firstly, a review of anthropological theory, assessing its role in the context of contemporary theoretical developments in the Humanities. To do so, I developed the metaphor of the metamorphoses of the ethnographic eye, which allowed me to detect some crucial moments of the reception and reproduction, in peripheral countries such as Brazil, of this knowledge created in metropolitan places in the days of colonialism. Secondly, I review the ideas of some leading theorists of postcolonial and subaltern studies, such as Edward Said, Gayatri Spivak and Homi Bhabha. Thirdly, I discuss the possibilities of a postcolonial ethnography, aimed at the narration of subaltern voices, which puts Anthropology close to Comparative Literature. Finally, I illustrate these discussions with the presentation of an extraordinary narrative of a woman gatherer of baba

    Full Text Available Abstract Background Endogenous retroviruses (ERVs are remnants of exogenous retroviruses that have integrated into the nuclear DNA of a germ-line cell. Here we present the results of a survey into the ERV complement of Crocodylus porosus, the saltwater crocodile, representing 45 individuals from 17 sampling locations in the Northern Territory of Australia. These retroelements were compared with published ERVs from other species of Crocodylia (Crocodilians; alligators, caimans, gharials and crocodiles as well as representatives from other vertebrates. This study represents one of the first in-depth studies of ERVs within a single reptilian species shedding light on the diversity of ERVs and proliferation mechanisms in crocodilians. Results Analyses of the retroviral pro-pol gene region have corroborated the presence of two major clades of ERVs in C. porosus and revealed 18 potentially functional fragments out of the 227 recovered that encode intact pro-pol ORFs. Interestingly, we have identified some patterns of diversification among those ERVs as well as a novel sequence that suggests the presence of an additional retroviral genus in C. porosus. In addition, considerable diversity but low genetic divergence within one of the C. porosus ERV lineages was identified. Conclusions We propose that the ERV complement of C. porosus has come about through a combination of recent infections and replication of ancestral ERVs. Strong purifying selection acting on these clades suggests that this activity is recent or still occurring in the genome of this species. The discovery of potentially functional elements is an interesting development that warrants further investigation.

All were in the stage II or III of Hoehn and Yahr scale (H&Y. PPX were started at 0.125 mg/day and daily doses were increased to 1.5 mg/day. At 3 months after PPX treatment, patients were re-evaluated. Hamilton Depression Rating Scale (HAM-D, Unified Parkinson’s Disease Rating Scale III, H&Y stage, and freezing of gait questionnaire were compared in patients before and after PPX treatment. These scores were significantly improved after PPX administration. There were no correlations between HAM-D and those motor functions.

    Full Text Available In this article, we analyze the main non-wood forest products from Brazilian savanna. We studied the behavior and the growth rates of production and prices of almond of babaçu, oil of copaiba, fiber of buriti, leaf of jaborandi, bark of barbatimão, bark of angico, fruit of mangaba, almonds of pequi, from 1982 to 2005. All the products exhibited decreasing production, with exception of the oil of copaiba and almonds of pequi, which showed positive growth rates: 12.9% and 8.5%, respectively. The analysis of prices for most products was not significant, except for barks of barbatimão and angico, and almonds of pequi, which showed positive trends: 10.9%, 6.7%, and 4.6%, respectively. We believe that results were not significant due to the severe variations of the Brazilian currency in the period. We conclude that pequi is the main product from savanna and that oil of copaiba has the biggest increase in the production because most of the production comes from the whole Brazilian Amazon region.

    HYBRIDCHECK is a software package to visualize the recombination signal in large DNA sequence data set, and it can be used to analyse recombination, genetic introgression, hybridization and horizontal gene transfer. It can scan large (multiple kb) contigs and whole-genome sequences of three or more individuals. HYBRIDCHECK is written in the r software for OS X, Linux and Windows operating systems, and it has a simple graphical user interface. In addition, the r code can be readily incorporated in scripts and analysis pipelines. HYBRIDCHECK implements several ABBA-BABA tests and visualizes the effects of hybridization and the resulting mosaic-like genome structure in high-density graphics. The package also reports the following: (i) the breakpoint positions, (ii) the number of mutations in each introgressed block, (iii) the probability that the identified region is not caused by recombination and (iv) the estimated age of each recombination event. The divergence times between the donor and recombinant sequence are calculated using a JC, K80, F81, HKY or GTR correction, and the dating algorithm is exceedingly fast. By estimating the coalescence time of introgressed blocks, it is possible to distinguish between hybridization and incomplete lineage sorting.

    Full Text Available The triatomine species Rhodnius nasutus and Triatoma pseudomaculata were captured on palm trees Orbignya martiana "babaçu ", in the urban zone of Teresina. This kind of palm tree is largely distributed in Piauí State. The predominant species was R. nasutus; the young in stars predominated. The infestation index of palm trees and the infection index of triatomines by flagellates were 96.0 ana 29.1%, respectively. Marsupiais, bats and a rodent were captured in palm trees. The flagellates found in both triatomines ana marsupiais were morphologically and biologically indistinguishable from Trypanosoma cruzi. Forty seven percent (481/1,025 of triatomines were found concentrated in six palm trees where marsupiais circulated. Of the total of 1,025 triatomines 230 (22% were infected by flagellates and 53.0% (123/230 of these infected triatomines were present in the same six palm trees. No evidence of triatomine domiciliation or human transmission was observed in the houses in the vicinity of palm trees. The results suggest that marsupiais play an important role in the life-cycle of T. cruzi in this region. The natural focus of Chagas' disease, demonstrated in the present study could represent a potential epidemiological threat.

    Helicobacter pylori is one of the most common pathogens affecting humankind, infecting approximately 50% of the world's population. Of those infected, many will develop asymptomatic gastritis, but 10% develop gastric or duodenal ulcers. The clinical outcome of the infection may involve a combination of bacterial factors, host factors and environmental factors. In the process of development of gastritis, ulceration and cancer, several cellular and molecular steps follow each other. Infection, acid survival, adhesion, cytotoxicity, epithelial cell turnover changes, inflammation, regeneration or pathological alteration towards erosions, ulceration, and cancer can be observed on the cellular level. Bacterial factors like urease, AmiE, AmiF, hydrogenase and arginase are needed for survival in the acidic gastric environment. The bacterial flagellae are essential to move the bacteria towards the epithelial surface. Adhesive factors like BabA, SabA and ureaseA are necessary for adhesion against MHC-II complexes and Le antigens. The bacteria VacA and CagA are cytotoxic factors. The Cag type IV secretion system delivers these proteins inside the epithelial cells. After disruption of epithelial cell junctions, the bacteria can pass through the gastric wall facing direct immune response from neutrophils, lymphocytes, mast cells and dendritic cells. This review describes and summarizes our present molecular biological information and knowledge about the Helicobacter infective component, cell functions and processes. The possible role of host counter responses and interactions with gastric epithelia and immune cells are also detailed. PMID:21088410

    If a flow obstacle such as a spacer is placed in a boiling two-phase flow within a channel, the temperature on the surface of the heating tube is severely affected by the existence of the spacer. Under certain conditions the spacer has a cooling effect, and under other conditions the spacer causes dryout of the cooling water film on the heating surface, resulting in burnout of the tube. The burnout mechanism near the spacer, however, remains unclear. In a previous paper (Fukano, T., Mori, S., Akamatsu, S., Baba, A., 2002. Relation between temperature fluctuation of a heating surface and generation of drypatch caused by a cylindrical spacer in a vertical boiling two-phase upward flow in a narrow annular channel. Nucl. Eng. Des. 217, 81-90), we reported that the disturbance wave has a significant effect on dryout occurrence. Therefore, in the present paper, the relation between dryout, burnout occurrence, and interval between two successive disturbance waves obtained from the differential pressure fluctuation caused by the disturbance waves passing by a spacer, is further discussed in detail.

    Typical multivariate time series models may exhibit comovement in mean but not in variance of hydrologic and climatic variables. This paper introduces multivariate generalized autoregressive conditional heteroscedasticity (GARCH) models to capture the comovement of the variance or the conditional covariance between two hydroclimatic time series. The diagonal vectorized and Baba-Engle-Kroft-Kroner models are developed to evaluate the covariance between drought and two atmospheric circulations, Southern Oscillation Index (SOI) and North Atlantic Oscillation (NAO) time series during 1954-2000. The univariate generalized autoregressive conditional heteroscedasticity model indicates a strong persistency level in conditional variance for NAO and a moderate persistency level for SOI. The conditional variance of short-term drought index indicates low level of persistency, while the long-term index drought indicates high level of persistency in conditional variance. The estimated conditional covariance between drought and atmospheric indices is shown to be weak and negative. It is also observed that the covariance between drought and atmospheric indices is largely dependent on short-run variance of atmospheric indices rather than their long-run variance. The nonlinearity and stationarity tests show that the conditional covariances are nonlinear but stationary. However, the degree of nonlinearity is higher for the covariance between long-term drought and atmospheric indices. It is also observed that the nonlinearity of NAO is higher than that for SOI, in contrast to the stationarity which is stronger for SOI time series.

    In this research, the performance of Polyaluminium Chloride (PAC) and Polyaluminium Chloride sludge (PACS) as coagulants for acid red 119 (AR119) dye removal from aqueous solutions were compared. The sample of PACS was collected from "Baba Sheikh Ali" water treatment plant (Isfahan, Iran) where PAC is used as a coagulant in the coagulation/flocculation process. A response surface methodology was applied to evaluate the simple and combined effects of the operating variables including initial pH, coagulant dosage and initial dye concentration and to optimize the operating conditions of the treatment process. Results reveal that the optimal conditions for dye removal were initial pH 3.42, coagulant dosage of 4.55 g dried PACS/L and initial dye concentration of 140 mg/L for PACS, while the optimal initial pH, coagulant dosage and initial dye concentration for PAC were 3.8, 57 mg/L and 140 mg/L, respectively. Under these optimal values of process parameters, the dye removal efficiency of 94.1% and 95.25% was observed for PACS and PAC, respectively. Although lower amount of PAC in comparison with PACS was needed for specific dye removal, the reuse of PACS as a low-cost material can offer some advantages such as high efficiency for AR119 dye removal and economic savings on overall water and wastewater treatment plant operation costs.

    The reservoir parameters (total gross thickness, shale volume, total porosity, effective porosity, water saturation, bulk pore volume, net pay thickness and oil in place indicator) of Kareem and Belayim formations are studied through nine wells and mapped to show the aerial distribution of these parameters. Interpretation of these maps showed that, the best locations of hydrocarbon accumulation in Belayim marine oil field are middle part, northeast and the south west directions for Kareem formation and southwest and northeast directions for Belayim formation. The petrophysical results of Belayim formation were presented in the form of 3D slicing models to exhibit the variation of these parameters in the different directions. Cross plots of Kareem formation were done using neutron, density and sonic logs which is directly influenced by the matrix composition. By using two or three porosity logs reading we determined the porosity and evaluated the matrix characteristics of Kareem formation as it is considered as a good reservoir for oil and gas and mainly composed of sand stone. Finally, facies maps for Kareem and Belayim formations which established using composite logs indicate that, the environment of deposition of Kareem formation was deep marine in the middle and northern parts and shallow in the southern parts of the study area, meanwhile in Belayim formation the environment of deposition was in lagoonal through the deposition of Baba and Feiran members and shallow to deep during the sedimentation of Sidri and Hammam Faraun members.

    2002-01-01

    This study examined the effects of two types of instructions on the academic responding of 4 children with attention deficit hyperactivity disorder. Tactical instructions specified how to distribute responding between two concurrently available sets of math problems associated with different variable-interval schedules of reinforcement. Strategic instructions provided a strategy to determine the best way to distribute responding. Instruction conditions were counterbalanced in an ABAB/BABA reversal design nested within a multiple baseline across participants design. Experimental sessions consisted of a learning session in which participants were provided with one type of instruction, followed by a test session in which no instruction was provided. The schedules of reinforcement were subsequently reversed during test sessions. When learning and test schedules were identical, the responding of all 4 participants closely matched the reinforcement schedules. When tactical instructions were provided and schedules were subsequently changed, responding often remained under the control of the instructions. When strategic instructions were provided, responding more quickly adapted to the changed contingencies. Analysis of postsession verbal reports indicated correspondence between the participants' verbal descriptions (whether accurate or inaccurate) and their nonverbal patterns of responding.

    Full Text Available Trypanosoma cruzi infected Rhodnius robustus and/or Rhodnius pictipes were commonly found, in large numbers, in the Brazilian Amazonian palms Maximiliana regia ("inajá", Acrocomia sclerocarpa ("mucajá" and Orbignya speciosa ("babaçu". The common opossum, Didelphis marsupialis, was the animal most frequently associated with triatomine infested palms. R. pictipes, frequently light-attracted into houses from palm trees, was the probable source of an acute case of Chagas' disease in the vicinity of Belém. It is considered that triatomine infested palms are likely to cause some cases of acute Chagas' disease in the States of Amazonas and Rondônia.

    Full Text Available Background: Cancer has become one of the ten leading causes of death in India. Breast cancer is the most common diagnosed malignancy in India, it ranks second to cervical cancer. An increasing trend in incidence is reported from various registries of national cancer registry project and now India is a country with largest estimated number of breast cancer deaths worldwide. Aim: To study the factors associated with breast cancer. Objectives: To study the association between breast cancer and selected exposure variables and to identify risk factors for breast cancer. Materials and Methods: A hospital based Case control study was conducted at Shirdi Sai Baba Cancer Hospital and Research Center, Manipal, Udupi District. Results: Total 188 participants were included in the study, 94 cases and 94 controls. All the study participants were between 25 to 69 years of age group. The cases and controls were matched by ± 2 years age range. Non vegetarian diet was one of the important risk factors (OR 2.80, CI 1.15-6.81. More than 7 to 12 years of education (OR 4.84 CI 1.51-15.46 had 4.84 times risk of breast cancer as compared with illiterate women. Conclusion: The study suggests that non vegetarian diet is the important risk factor for Breast Cancer and the risk of Breast Cancer is more in educated women as compared with the illiterate women. Limitation: This is a Hospital based study so generalisability of the findings could be limited.

  17. Ages and Compositions of the Precambrian High-grade Basement of the Qilian Terrane and Its Adjacent Areas

    Based on geological, chronological, geochemical and Nd isotopicstudies of the high-grade basement of the Qilian terrane, the authors have drawn the following main conclusions: (1) the high-grade basement of the Qilian terrane consists mainly of meta-argillo-arenaceous rocks and granites and its bulk part was formed in the period of 0.8-1.0 Ga (the Jinningian period); (2) most of the meta-argillo-arenaceous rocks and granitic rocks have strong negative Eu and Ba anomalies (Eu/Eu*= 0.47-0.71 and Ba/Ba*= 0.16-0.64), with tDM and εNd (1.0 Ga) ranging from 1.87 to 2.26 Ga and from -8.54 to -4.06 respectively, showing relatively high maturity; and (3) the Jinningian granitic rocks are a typical product of continent-continent collision, being probably related to the formation of the supercontinent Rodinia. These studies, com bined with the study of high-grade basement rocks near the Qilian terrane, suggest that before the Jinningian period, the Qilian-Qaidam northern-margin terrane and Dunhuang-Alxa terrane were separated from each other, belonging to differ ent plate systems of the North China craton and Yangtze platform respectively. The Qilian orogenic belt was the same as or similar to the Qiling orogenic belt in terms of the geological evolution history at least before the Jinningian period.

  19. Evaluating the level and nature of sustainable development for a geothermal power plant

    International Nuclear Information System (INIS)

    The paper provides for an evaluation of the potential level and nature of sustainable development of the Sabalan geothermal power plant in NW Iran, to be operational in 2011. The paper achieves this by applying a mathematical model of sustainable development developed by the author (re: Phillips), in respect to the Environmental Impact Assessment (EIA) conducted by Yousefi et al. using the Rapid Impact Assessment Matrix (RIAM) methodology (re: Pastakia; Pastakia and Jensen). Using a model application methodology developed for the RIAM, the results indicated that the nature of sustainable development for Sabalan was considered to be very weak (S = 0.063). This was due to the imbalance between negative environmental impacts and positive socio-economic impacts deriving from the project. Further, when placed into context with a similar set of results obtained from the EIA of the Tuzla geothermal power plant by Baba also using the RIAM methodology, then the similarities between the results obtained raises some legimate questions as to the sustainable development credentials of geothermal power production.

    The setting up of the National Rural Health Mission is yet another political move by the present government of India to make yet another promise to the long suffering rural population to improve their health status. As has happened so often in the past, it is based on questionable premises. It adopts a simplistic approach to a highly complex problem. The Union Ministry of Health and Family Welfare and its advisors, either because of ignorance or otherwise, have doggedly refused to learn from the many experiences of the past, both in terms of the efforts to earlier somewhat sincere efforts to develop endogenous mechanisms to offer access to health services as well as from the devastative impact on the painstakingly built rural health services of the imposition of prefabricated, ill-conceived, ill-formulated, techno-centric vertical programmes on the people of India. The also ignore some of the basic postulates of public health practice in a country like India. That did not substantiate the bases of some of their substantive contentions with scientific data obtained from health systems research reveals that they are not serious about their promise to rural population. This is yet another instance of what Romesh Thaper had called 'Baba Log playing government government'.

  7. Helicobacter pylori infection in children: should it be carefully assessed?

    The prevalence of H. pylori infection, mainly acquired during childhood and may be persisting throughout life, has been found high in developing countries; this high prevalence is related to low socioeconomic status. The persistence of bacterium exposure is related to gastritis and other severe complications including peptic ulcer, lymphoma MALT and gastric cancer, which are rarely present in the pediatric age due to a lower inflammatory and immunological response. Virulence factors, host gastric mucosal factors, and the natural environment of patients are associated with the clinical outcome of H. pylori infection. The main bacterial virulence factors include adhesins (BabA, SabA), vacuolating cytotoxin VacA, and the products of the cag pathogenicity island (cag PAI). There are geographic differences between cagA, vacA status and H. pylori related diseases. The main criteria to evaluate H. pylori infection in children are gastrointestinal and extra gastrointestinal manifestations related to H. pylori infection, familial history of gastric cancer, peptic ulcer, lymphoma MALT, symptomatic children living in high prevalence regions, and immigrant or adopted children in developed countries. Early detection of H. pylori and its virulence factors, in addition to effective methods of eradication associated with prevention programs, may lead to the decrease of H. pylori incidence and gastritis, especially in endemic high-risk regions. The early assessment in children may prevent further severe complications in adulthood. PMID:27212173

    Full Text Available Polysaccharide containing extracts from immature fruits of okra (Abelmoschus esculentus are known to exhibit antiadhesive effects against bacterial adhesion of Helicobacter pylori (H. pylori to stomach tissue. The present study investigates structural and functional features of polymers responsible for this inhibition of bacterial attachment to host cells. Ammonium sulfate precipitation of an aqueous extract yielded two fractions at 60% and 90% saturation with significant antiadhesive effects against H. pylori, strain J99, (FE60% 68% ± 15%; FE90% 75% ± 11% inhibition rates after preincubation of the bacteria at 1 mg/mL. Sequential extraction of okra fruits yielded hot buffer soluble solids (HBSS with dose dependent antiadhesive effects against strain J99 and three clinical isolates. Preincubation of H. pylori with HBSS (1 mg/mL led to reduced binding to 3ʹ-sialyl lactose, sialylated Lea and Lex. A reduction of bacterial binding to ligands complementary to BabA and SabA was observed when bacteria were pretreated with FE90%. Structural analysis of the antiadhesive polysaccharides (molecular weight, monomer composition, linkage analysis, stereochemistry, and acetylation indicated the presence of acetylated rhamnogalacturonan-I polymers, decorated with short galactose side chains. Deacetylation of HBSS and FE90% resulted in loss of the antiadhesive activity, indicating esterification being a prerequisite for antiadhesive activity.

    Absorption of medium chain triglycerides (MCT) was estimated in 10 patients with stagnant loop syndrome (SLS). Six patients had steatorrhea due to gastrojejunal anastomosis and 4 due to diabetic neuropathy. The diagnosis of SLS was confirmed by antibiotic therapeutic test after exclusion of other causes of malabsorption syndrome. Each patient was submitted to 2 types of diet during one week each, differing only in the type of added lipid. In the diet with long chain triglycerides (LCT), soy oil and butter were added. In the diet, with medium chain triglycerides, only MCT oil from babaçu was added. The excretion of lipid was determined in the feces in the last 3 days of each diet. The results showed that the medium fecal lipid excretion was 48.6 (sd = 19.8) g/d in the LCT diet and 26.6 (sd = 13.8) g/d in the MCT [d = 22.0; s(d) = 3.10; t = 7.10; p less than 0.001], which indicates that in patients with SLS, MCT diet was better absorbed than LCT diet. It is suggested that MCT oil may be used as a caloric source during nutritional recovery in SLS.

  10. Genetic battle between Helicobacter pylori and humans. The mechanism underlying homologous recombination in bacteria, which can infect human cells.

    Helicobacter pylori is a gram-negative pathogenic bacterium that colonises the human stomach. The chronic infection it causes results in peptic ulcers and gastric cancers. H. pylori can easily establish a chronic infection even if the immune system attacks this pathogen with oxidative stress agents and immunoglobulins. This is attributed to bacterial defence mechanisms against these stresses. As a defence mechanism against oxidative stresses, in bacterial genomes, homologous recombination can act as a repair pathway of DNA's double-strand breaks (DSBs). Moreover, homologous recombination is also involved in the antigenic variation in H. pylori. Gene conversion alters genomic structures of babA and babB (encoding outer membrane proteins), resulting in escape from immunoglobulin attacks. Thus, homologous recombination in bacteria plays an important role in the maintenance of a chronic infection. In addition, H. pylori infection causes DSBs in human cells. Homologous recombination is also involved in the repair of DSBs in human cells. In this review, we describe the roles of homologous recombination with an emphasis on the maintenance of a chronic infection.

    Helicobacter pylori (H. pylori) colonizes the gastric mucosa of over 50% of the world population, causing several pathologies, such as gastric ulcers and gastric cancer. Since current antibiotic treatments are inefficient in 20% of cases alternative therapies are needed. This work reports the ability of chitosan microspheres to adhere to H. pylori and prevent/remove H. pylori colonization. Adhesion of H. pylori strains with different functional adhesins (BabA and/or SabA) to chitosan microspheres (diameter 167 ± 27 μm) occurs at both pH 2.6 and 6.0, but is higher at pH 6.0. Bacterial adhesion to a gastric cell line expressing sialylated carbohydrates (SabA receptors) was performed at the same pH values using H. pylori strains with and without SabA. At both pH values addition of microspheres to gastric cells before and after pre-incubation with H. pylori decreased bacterial adhesion to cells. Furthermore, the chitosan microspheres were non-cytotoxic. These findings reveal the potential of chitosan microspheres as an alternative or complementary treatment for H. pylori gastric eradication or prevention of H. pylori colonization.

The patient was a 73-year-old man who had had a nodule on the left lower eyelid for two years. He was referred to our hospital with a diagnosis of a swollen chalazion. The clinical and histopathological records were reviewed and the mass was excised. Histopathological examination revealed a mucinous sweat gland adenocarcinoma. Postoperative magnetic resonance imaging and positron emission tomography excluded systemic metastases. After the histopathological findings, a complete surgical excision of the margins of the adenocarcinoma was performed, with histopathological confirmation of negative margins. After the final histopathological examination, the patient was diagnosed with a primary mucinous sweat gland adenocarcinoma of the left eyelid. Six months after the surgery, no recurrence has been observed. Because the appearance of mucinous sweat gland adenocarcinoma of the eyelid is quite variable, the final diagnosis can only be made by histopathological examination. A complete surgical excision is recommended.Keywords: complete surgical excision, eyelid, initial stage, mucinous sweat gland adenocarcinoma

  13. Relation between the occurrence of Burnout and differential pressure fluctuation characteristics caused by the disturbance waves passing by a flow obstacle in a vertical boiling two-phase upward flow in a narrow annular channel

    International Nuclear Information System (INIS)

    If a flow obstacle such as a spacer is placed in a boiling two-phase flow within a channel, the temperature on the surface of the heating tube is severely affected by the existence of the spacer. Under certain conditions the spacer has a cooling effect, and under other conditions the spacer causes dryout of the cooling water film on the heating surface, resulting in burnout of the tube. The burnout mechanism near the spacer, however, remains unclear. In a previous paper (Fukano, T., Mori, S., Akamatsu, S., Baba, A., 2002. Relation between temperature fluctuation of a heating surface and generation of drypatch caused by a cylindrical spacer in a vertical boiling two-phase upward flow in a narrow annular channel. Nucl. Eng. Des. 217, 81-90), we reported that the disturbance wave has a significant effect on dryout occurrence. Therefore, in the present paper, the relation between dryout, burnout occurrence, and interval between two successive disturbance waves obtained from the differential pressure fluctuation caused by the disturbance waves passing by a spacer, is further discussed in detail

    The diel vertical distribution of fish larvae off the Balearic Islands during late autumn and summer was analysed in relation to the environmental conditions. Four fixed sampling stations, located in the outer shelf and slope zones, were sampled during both the day and night by means of oblique hauls at different water depths. In autumn the first 60 m were characterised by vertical mixing and relatively higher fluorescence values, while summer was characterised by strong near-surface stratification and the presence of a Deep Fluorescence Maximum (DFM). The fish larval community was dominated by mesopelagic species, myctophiforms and stomiiforms, with some differences in species composition and their relative contribution between periods. A higher number of species was observed to reproduce in summer. The diel vertical distribution patterns differed among species and, within species, some differences were detected between the day and night. Although their relative depth preferences were similar between surveys, seasonal comparisons for the most abundant species showed that in autumn larvae presented both a shallower distribution during the day and a deeper distribution during the night than in the summer period. The larvae of all species, except for Argyropelecus hemigymnus, were absent from layers below 200 m. In these deeper layers, only A. hemigymnus larvae and juvenile stages of myctophiforms and stomiiforms were found. Another group of species, including Hygophum benoiti, Ceratoscopelus maderensis, Cyclothone braueri and Lampanyctus crocodilus, characterised the surface assemblage, mainly appearing in the first 50 m during the day, while at night their distribution was wider, extending to deeper layers. Benthosema glaciale, Symbolophorus veranyi and Myctophum punctatum were located at intermediate levels (mostly 50-100 m). Larval size stratification was evident for the most abundant species, with younger stages being found at shallower depths in the water

    Full Text Available The triatomine species Rhodnius nasutus and Triatoma pseudomaculata were captured on palm trees Orbignya martiana "babaçu ", in the urban zone of Teresina. This kind of palm tree is largely distributed in Piauí State. The predominant species was R. nasutus; the young in stars predominated. The infestation index of palm trees and the infection index of triatomines by flagellates were 96.0 ana 29.1%, respectively. Marsupiais, bats and a rodent were captured in palm trees. The flagellates found in both triatomines ana marsupiais were morphologically and biologically indistinguishable from Trypanosoma cruzi. Forty seven percent (481/1,025 of triatomines were found concentrated in six palm trees where marsupiais circulated. Of the total of 1,025 triatomines 230 (22% were infected by flagellates and 53.0% (123/230 of these infected triatomines were present in the same six palm trees. No evidence of triatomine domiciliation or human transmission was observed in the houses in the vicinity of palm trees. The results suggest that marsupiais play an important role in the life-cycle of T. cruzi in this region. The natural focus of Chagas' disease, demonstrated in the present study could represent a potential epidemiological threat.As espécies de triatomíneos Rhodnius nasutus e Triatoma pseudomaculata foram capturados em palmeiras Orbignya martiana "babaçu", situadas na zona urbana de Teresina. Este tipo de palmeira é largamente distribuída no Estado do Piauí. R. nasutus foi a espécie predominante. O índice de infestação das palmeiras e o índice de infecção dos triatomíneos por flagelados foram 96.0 e 29.1%, respectivamente. O estádio de ninfa predominou entre os triatomíneos capturados. Em algumas palmeiras, foram capturados marsupiais, morcegos e um roedor. Os flagelados encontrados tanto nos triatomíneos como nos marsupiais eram morfologicamente e biologicamente indistinguíveis do Trypanosoma cruzi Quarenta e sete porcento (481

OSEME promoted a dose-dependent decrease on the viability of all cells. This effect was much more pronounced on the tumoral cell lines than on non-tumoral cells, a phenomenon revealed by the dose of OSEME which promotes half of maximal effect (ID50. The decrease on viability was followed by shrinkage of cells, alteration on their morphology, and a markedly nuclear condensation. Curiously, stimulation of 6-phosphofructokinase activity (6.6-times was observed on HL-60 cells, treated with OSEME, when compared to control treated with ethanol (vehicle.

    The thermally evaporated layer structured BaI{sub 2} grows in various completely preferred (hkl) film orientations with different growth parameters like film thickness, deposition rate, substrate temperature, etc. which were characterized by structural, morphological, and optical absorption measurements. Structural analysis reveals the strain in the films and the optical absorption shows a direct type band gap. The varying band gaps of these films were found to scale linearly with their strain. The elastic moduli and other constants were also calculated using Density Functional Theory (DFT) formalism implemented in WIEN2K code for converting the strain into residual stress. Films of different six (hkl) orientations show stress free anisotropic band gaps (2.48–3.43 eV) and both positive and negative pressure coefficients. The negative and positive pressure coefficients of band gap are attributed to the strain in I-I (or Ba-Ba or both) and Ba-I distances along [hkl], respectively. The calculated band gaps are also compared with those experimentally determined. The average pressure coefficient of band gap of all six orientations (−0.071 eV/GPa) found to be significantly higher than that calculated (−0.047 eV/GPa) by volumetric pressure dependence. Various these issues have been discussed with consistent arguments. The electron effective mass m{sub e}{sup *}=0.66m{sub 0} and the hole effective mass m{sub h}{sup *}=0.53m{sub 0} have been determined from the calculated band structure.

  2. Molecular mechanisms of gastric epithelial cell adhesion and injection of CagA by Helicobacter pylori

    2011-11-01

    Abstract Helicobacter pylori is a highly successful pathogen uniquely adapted to colonize humans. Gastric infections with this bacterium can induce pathology ranging from chronic gastritis and peptic ulcers to gastric cancer. More virulent H. pylori isolates harbour numerous well-known adhesins (BabA\\/B, SabA, AlpA\\/B, OipA and HopZ) and the cag (cytotoxin-associated genes) pathogenicity island encoding a type IV secretion system (T4SS). The adhesins establish tight bacterial contact with host target cells and the T4SS represents a needle-like pilus device for the delivery of effector proteins into host target cells such as CagA. BabA and SabA bind to blood group antigen and sialylated proteins respectively, and a series of T4SS components including CagI, CagL, CagY and CagA have been shown to target the integrin β1 receptor followed by injection of CagA across the host cell membrane. The interaction of CagA with membrane-anchored phosphatidylserine may also play a role in the delivery process. While substantial progress has been made in our current understanding of many of the above factors, the host cell receptors for OipA, HopZ and AlpA\\/B during infection are still unknown. Here we review the recent progress in characterizing the interactions of the various adhesins and structural T4SS proteins with host cell factors. The contribution of these interactions to H. pylori colonization and pathogenesis is discussed.

    If a flow obstacle, such as a spacer is placed in a boiling two-phase flow within a channel, the temperature on the surface of the heating tube is severely affected by the existence of the spacer. Under certain conditions, a spacer has a cooling effect, and under other conditions, the spacer causes dryout of the cooling water film on the heating surface. The burnout mechanism, which always occurs upstream of a spacer, however, remains unclear. In a previous paper [Fukano, T., Mori, S., Akamatsu, S., Baba, A., 2002. Relation between temperature fluctuation of a heating surface and generation of drypatch caused by a cylindrical spacer in a vertical boiling two-phase upward flow in a narrow annular channel. Nucl. Eng. Des. 217, 81-90], we reported that the disturbance wave has a significant effect on dryout and burnout occurrence and that a spacer greatly affects the behavior of the liquid film downstream of the spacer. In the present study, we examined in detail the influences of a spacer on the heat transfer and film thickness characteristics downstream of the spacer by considering the result in steam-water and air-water systems. The main results are summarized as follows: (1)The spacer averages the liquid film in the disturbance wave flow. As a result, dryout tends not to occur downstream of the spacer. This means that large temperature increases do not occur there. However, traces of disturbance waves remain, even if the disturbance waves are averaged by the spacer. (2)There is a high probability that the location at which burnout occurs is upstream of the downstream spacer, irrespective of the spacer spacing. (3)The newly proposed burnout occurrence model can explain the phenomena that burnout does occur upstream of the downstream spacer, even if the liquid film thickness t{sub Fm} is approximately the same before and behind the spacer.

Methods: In all, 126 eyes of 63 emmetropic subjects (mean age: 21.17±6.76 years; range: 10–37 years were assessed for macular thickness and macular volume, using spectral domain-optical coherence tomography over 6×6 mm2 in the posterior pole. A fast macular thickness protocol was employed. Statistics such as the mean, median, standard deviation, percentiles, and range were used, while a P-value was set at 0.05 to test significance. Results: Average macular thickness and total macular volume were larger in males compared to females. With each year of increasing age, these variables decreased by 0.556 µm and 0.0156 mm3 for average macular thickness and total macular volume, respectively. The macular thickness was greatest in the inner superior section and lowest at the center of the fovea. The volume was greatest in the outer nasal section and thinnest in the fovea. The central subfield thickness (r=-0.243, P=0.055 and foveal volume (r=0.216, P=0.09 did not correlate with age. Conclusion: Males and females differ significantly with regard to macular thickness and macular volume measurements. Reports by other studies that the increase in axial length reduced thickness and volume, were negated by this study which found a positive correlation among axial length, thickness, and volume.

    AIM: Studies on Helicobacter pylori(Hpylori) and gastroduodenal diseases have focused mainly on the distal sites of the stomach, but relationship with the gastric cardia is lacking. The aim of this study is to determine if the gastric topology and genotypic distribution of H pylori were associated with different upper gastrointestinal pathologies in a multiethnic Asian population.METHODS: Gastric biopsies from the cardia, body/corpus and antrum were endoscoped from a total of 155 patients with dyspepsia and/or reflux symptoms, with informed consent. H pylori isolates obtained were tested for the presence of 26kDa, ureC, cagA, vacA, iceA1, iceA2 and babA2 genes using PCR while DNA fingerprints were generated using random amplification polymorphic DNA(RAPD).RESULTS: H pyloriwas present in 51/155 (33%) of patients studied. Of these, 16, 15 and 20 were isolated from patients with peptic ulcer diseases, gastroesophageal reflux diseases and non-ulcer dyspepsia, respectively. Of the H pylori positive patients, 75% (38/51) had H pylori in all three gastric sites.The prevalence of various genes in the H pylori isolates was shown to be similar irrespective of their colonization sites as well as among the same site of different patients.The RAPD profiles of H pylori isolates from different gastric sites were highly similar among intra-patients but varied greatly between different patients.CONCLUSION: Topographic colonization of H pylori and the virulence genes harboured by these isolates have no direct bearing to the clinical state of the patients. In multiethnic Singapore, the stomach of each patient is colonized by a predominant strain of H pylori, irrespective of the clinical diagnosis.

    Full Text Available The attempts to challenge conventional gendered discourses in children's fantasy have often resulted in feminist rewritings of earlier stories. Ghost dance (1994 by the English author Susan Price is a novel that reflects a specific feminist poetics of rewriting: metafictional passages highlight the constructedness of the narrative and at the end readers are invited to tell their own versions of the story. Moreover, the rewriting freely combines and recontextualises elements from different source texts and reformulates them to create a narrative that challenges conventional discourses of gender. While this poetics has an appeal from a feminist perspective, the play with cross-cultural intertexts and gender becomes more complex when the novel is examined in a postcolonialist framework in relation to ethnicity and the issue of cultural appropriation. Ghost dance is situated in a setting that has a real-world equivalent (Russia, involves characters that are identified with names of real-world ethnic groups (Lapps (Sámi, Russian, and mixes elements from Russian wonder tales, Nordic mythology and an Ojibwe legend. The novel does not aim at historical accuracy in its representations nor is it a direct retelling of any of the pre-texts but combines motifs, themes, names, characters and settings freely from each source. In this textual melting pot, the protagonist Shingebiss is, on one level, a revision of the witch Baba Yaga, but also described as a Lappish shaman with an Ojibwe name. To rewrite gendered discourses, certain elements from the pretexts are chosen and others left out – the question is, then, what effects does this recontextualisation have on the representation of ethnicity? Or, are the feminist rewriting strategies actually a form of cultural appropriation?

    Full Text Available Atrophy of the gastric mucosa is a precursor of intestinal-type gastric cancer, and Helicobacter pylori infection causes atrophic gastritis. The aim of this study was to determine whether the genetic diversity of H. pylori virulence genes is associated with the development and progression of gastric atrophy in humans. We isolated and cultured H. pylori strains from patients with gastric ulcer and duodenal ulcer accompanied by atrophic gastritis in background mucosa. H. pylori strains were stored at -80℃ prior to the experiments being carried out. We analyzed iceA, babA, vacA, cagA, and cagE genes by PCR. The cagA gene was analyzed through sequencing of the C-terminal region containing the EPIYA motif, which is related to tyrosine phosphorylation. Severe atrophy was observed in patients with gastric ulcer. The major phenotype of the vacA gene was s1c/m1 (93オ. The cagA gene was detected in all strains. The cagE gene was not detected in 2 and 5 strains from the mild cases and severe cases, respectively. The major cagA EPIYA motif, which is amino acids repeat in the C terminus, was the A-B-D type (44 of 58 strains. The virulence genes were not statistically associated with the severity of atrophy in the background gastric mucosa in humans. Not only identification of bacterial virulence factors but also studies of the host response will be necessary to investigate the progression of gastric atrophy and subsequent cancer development in humans.

    The mantle upwellings are one of the most important features for understanding the mantle dynamics. A large-scale mantle upwelling beneath the French Polynesia region in the South Pacific has been suggested from seismic studies, which is called the South Pacific superplume, and a slow velocity anomaly continues from the core mantle boundary to the upper mantle just beneath the Society hotspot (e.g., Suetsugu et al., 2009). However, the previous studies are not enough to understand the geometry, temperature, and composition of the Society hotspot. Then, we carried out the TIARES project that composed of multi-sensor stations that include broadband ocean bottom seismometers, ocean bottom electromagnetometers (OBEMs), and differential pressure gauges from 2009 to 2010 (Suetsugu et al., 2012). In this study, we will present the results of observed data obtained from OBEMs. In order to obtain three-dimensional (3-D) image of the upwelling of the Society hotspot in terms of electrical conductivity, we newly settled eleven OBEMs. In addition to these data, the old data obtained by Nolasco et al. (1998) was reanalyzed, and we obtained magnetotelluric (MT) responses at 20 sites totally. A 3-D marine MT inversion program (Tada et al., 2012; Baba et al., 2013), which can treat topographic change distorting EM data, was applied to these MT responses to estimate 3-D electrical conductivity image beneath the seafloor. The result detected a 3-D shaped high conductive anomaly, like a thumb, elongating from the mantle transition zone to the uppermost upper mantle just below the Society hotspot. With regard to interpretations, we will make a presentation at another session (GD3.3/EMRP4.3/GMPV3.3/SM6.11).

    Full Text Available Connecting three generations of music enthusiasts, Goa Gil is an imposing figure in the world of psychedelic trance. If the title of his 2007 compilation registers intent, he is a Worldbridger. Bristling with motifs of world sacred sites and appropriated "tribal" icons, with Gil seated cross-legged upon the apex of a Mayan temple, the album's cover artwork confabulates the physical, spiritual and cultural worlds he professes to bridge. Leading world-wide "trance dance rituals" Goa Gil operates under the guise of a "techno-shaman", a "cyber-baba" and a selector/mixer of traditions whose rituals are reputedly timeless and universal. But this intent is performed amid a highly mobile lifestyle spread across diverse psychedelic music cultures, scenes and sensibilities in discrete times and places. From the 1960s Haight-Ashbury psychedelic rock scene, to the psychedelic jam band scene on Anjuna beach, Goa, India, in the 1970s, to the adoption of electronic music in a DJ-led scene in the 1980s, to the birth of "Goa trance" in the 1990s, to his selection, production and performance of dark psychedelic trance in the 1990s/2000s onwards, DJ Goa Gil's life spans a breathtaking panorama of this-worldly psychedelic scenes. Gil is a freak bricoleur, an anomalous figure who evades modest circumscription. A Californian exile and sanctioned Shaivite practitioner with a professional hankering for darkpsy (as a DJ-producer, a hippie broker of the "Cosmic Spirit" and a post-apocalyptic punk, he is a spiritual authority and cultural outlaw touring the planet with an improbable mix of semiotic and sonic baggage. What's more, celebrated as a champion of the "Goa vibe" or derogated as an accomplice to its demise, Gil is a controversial figure who is the embodiment of considerable ambivalence. This article explores this holiest of anomalies in the world of DJing.

    Full Text Available This paper addresses the topic of the identity of Hindu religion and its impact on Christianity in the West (i.e. in Europe and USA, which is to be seen, especially through Neo-Hindu movements (that occurred mainly during 1950s–1980s. Thus, features and key terms such as: authority of the Veda, Dharma, moksha, samsāra and karma, the paths to liberation, concept of God, Brahman-ātman, avidyā and māyā and AUM are sketchily presented in the first part of the paper. There are obvious differences between both Hindu schools and Christian faith which regards 1. Ultimate concern: For the Hindu, it is escape from the human condition, whereas for the Christian it is freedom from guilt, sin, and the devil; 2. Human nature: For the Christian it is creaturely and sinful; for the Hindu it is divine; 3. Human problem: It is moral sin for the Christian and intellectual ignorance for the Hindu; 4. Resolution: For the Christian it is a divine act at infinite cost to God; for the Hindu it is human effort, sometimes mixed with grace, without cost to the god. In the second part it is presented the debated problem of Gurus and their movements and Neo-Hindu movements sprung at the second half of 20th century, such as Satya Sai Baba, International Society for Krishna Consciousness and meditation for “transcendental consciousness” (TM. In any case, the Indian offspring demonstrate that we have come to an important moment in the history of religions, one in which new religious landscapes continually emerge like the images of a kaleidoscope and where people will have to learn whether it is possible to share the same planet.

    Downy mildew caused by Sclerospora graminicola is a devastating disease of pearl millet. Based on candidate gene approach, a set of 22 resistance gene analogues were identified. The clone RGPM 301 (AY117410) containing a partial sequence shared 83% similarity to rice R-proteins. A full-length R-gene RGA RGPM 301 of 3552 bp with 2979 bp open reading frame encoding 992 amino acids was isolated by the degenerate primers and rapid amplification of cDNA ends polymerase chain reaction (RACE-PCR) approach. It had a molecular mass of 113.96 kDa and isoelectric point (pI) of 8.71. The sequence alignment and phylogenetic analysis grouped it to a non-TIR NBS LRR group. The quantitative real-time PCR (qRT-PCR) analysis revealed higher accumulation of the transcripts following inoculation with S. graminicola in the resistant cultivar (IP18296) compared to susceptible cultivar (7042S). Further, significant induction in the transcript levels were observed when treated with abiotic elicitor β-aminobutyric acid (BABA) and biotic elicitor Pseudomonas fluorescens. Exogenous application of phytohormones jasmonic acid or salicylic acid also up-regulated the expression levels of RGA RGPM 301. The treatment of cultivar IP18296 with mitogen-activated protein kinase (MPK) inhibitors (PD98059 and U0126) suppressed the levels of RGA RGPM 301. A 3.5 kb RGA RGPM 301 which is a non-TIR NBS-LRR protein was isolated from pearl millet and its up-regulation during downy mildew interaction was demonstrated by qRT-PCR. These studies indicate a role for this RGA in pearl millet downy mildew interaction. PMID:26842722

    Full Text Available Abstract Helicobacter pylori is a highly successful pathogen uniquely adapted to colonize humans. Gastric infections with this bacterium can induce pathology ranging from chronic gastritis and peptic ulcers to gastric cancer. More virulent H. pylori isolates harbour numerous well-known adhesins (BabA/B, SabA, AlpA/B, OipA and HopZ and the cag (cytotoxin-associated genes pathogenicity island encoding a type IV secretion system (T4SS. The adhesins establish tight bacterial contact with host target cells and the T4SS represents a needle-like pilus device for the delivery of effector proteins into host target cells such as CagA. BabA and SabA bind to blood group antigen and sialylated proteins respectively, and a series of T4SS components including CagI, CagL, CagY and CagA have been shown to target the integrin β1 receptor followed by injection of CagA across the host cell membrane. The interaction of CagA with membrane-anchored phosphatidylserine may also play a role in the delivery process. While substantial progress has been made in our current understanding of many of the above factors, the host cell receptors for OipA, HopZ and AlpA/B during infection are still unknown. Here we review the recent progress in characterizing the interactions of the various adhesins and structural T4SS proteins with host cell factors. The contribution of these interactions to H. pylori colonization and pathogenesis is discussed.

  15. Human gastric mucins differently regulate Helicobacter pylori proliferation, gene expression and interactions with host cells.

    Full Text Available Helicobacter pylori colonizes the mucus niche of the gastric mucosa and is a risk factor for gastritis, ulcers and cancer. The main components of the mucus layer are heavily glycosylated mucins, to which H. pylori can adhere. Mucin glycosylation differs between individuals and changes during disease. Here we have examined the H. pylori response to purified mucins from a range of tumor and normal human gastric tissue samples. Our results demonstrate that mucins from different individuals differ in how they modulate both proliferation and gene expression of H. pylori. The mucin effect on proliferation varied significantly between samples, and ranged from stimulatory to inhibitory, depending on the type of mucins and the ability of the mucins to bind to H. pylori. Tumor-derived mucins and mucins from the surface mucosa had potential to stimulate proliferation, while gland-derived mucins tended to inhibit proliferation and mucins from healthy uninfected individuals showed little effect. Artificial glycoconjugates containing H. pylori ligands also modulated H. pylori proliferation, albeit to a lesser degree than human mucins. Expression of genes important for the pathogenicity of H. pylori (babA, sabA, cagA, flaA and ureA appeared co-regulated in response to mucins. The addition of mucins to co-cultures of H. pylori and gastric epithelial cells protected the viability of the cells and modulated the cytokine production in a manner that differed between individuals, was partially dependent of adhesion of H. pylori to the gastric cells, but also revealed that other mucin factors in addition to adhesion are important for H. pylori-induced host signaling. The combined data reveal host-specific effects on proliferation, gene expression and virulence of H. pylori due to the gastric mucin environment, demonstrating a dynamic interplay between the bacterium and its host.

    Abstract Background Helicobacter mustelae causes gastritis, ulcers and gastric cancer in ferrets and other mustelids. H. mustelae remains the only helicobacter other than H. pylori that causes gastric ulceration and cancer in its natural host. To improve understanding of H. mustelae pathogenesis, and the ulcerogenic and carcinogenic potential of helicobacters in general, we sequenced the H. mustelae genome, and identified 425 expressed proteins in the envelope and cytosolic proteome. Results The H. mustelae genome lacks orthologs of major H. pylori virulence factors including CagA, VacA, BabA, SabA and OipA. However, it encodes ten autotransporter surface proteins, seven of which were detected in the expressed proteome, and which, except for the Hsr protein, are of unknown function. There are 26 putative outer membrane proteins in H. mustelae, some of which are most similar to the Hof proteins of H. pylori. Although homologs of putative virulence determinants of H. pylori (NapA, plasminogen adhesin, collagenase) and Campylobacter jejuni (CiaB, Peb4a) are present in the H. mustelae genome, it also includes a distinct complement of virulence-related genes including a haemagglutinin\\/haemolysin protein, and a glycosyl transferase for producing blood group A\\/B on its lipopolysaccharide. The most highly expressed 264 proteins in the cytosolic proteome included many corresponding proteins from H. pylori, but the rank profile in H. mustelae was distinctive. Of 27 genes shown to be essential for H. pylori colonization of the gerbil, all but three had orthologs in H. mustelae, identifying a shared set of core proteins for gastric persistence. Conclusions The determination of the genome sequence and expressed proteome of the ulcerogenic species H mustelae provides a comparative model for H. pylori to investigate bacterial gastric carcinogenesis in mammals, and to suggest ways whereby cag minus H. pylori strains might cause ulceration and cancer. The genome sequence was

Diffusion-weighted imaging (DWI and diffusion-weighted whole-body imaging with background body signal suppression (DWIBS are useful for this purpose.Patients and methods: One case of ESC with dysphagia presented at our hospital. Endoscopic examination revealed an elevated lesion with an ulcer, and stenosis was detected. DWI showed a high-intensity signal extending from the proximal to the distal ends of the carcinoma and extending to the tunica adventitia. A strong signal was also observed using 18F-fluorodeoxyglucose positron emission tomography (FDG-PET. DWIBS clearly revealed ESC, and these findings, along with those from DWI, suggested that our case had stage-T3 ESC. FDG-PET did not reveal the detailed structure of the ESC. DWIBS, on the other hand, showed that the signal extended to the tunica adventitia and the lumen of the esophagus.Conclusion: These findings suggest that DWI and DWIBS are useful for the detection and assessment of ESC.Keywords: positron emission tomography, endoscopy, computed tomography, cross section, squamous cell carcinoma

  18. On the occurrence of burnout downstream of a flow obstacle in boiling two-phase upward flow within a vertical annular channel

    International Nuclear Information System (INIS)

    If a flow obstacle, such as a spacer is placed in a boiling two-phase flow within a channel, the temperature on the surface of the heating tube is severely affected by the existence of the spacer. Under certain conditions, a spacer has a cooling effect, and under other conditions, the spacer causes dryout of the cooling water film on the heating surface. The burnout mechanism, which always occurs upstream of a spacer, however, remains unclear. In a previous paper [Fukano, T., Mori, S., Akamatsu, S., Baba, A., 2002. Relation between temperature fluctuation of a heating surface and generation of drypatch caused by a cylindrical spacer in a vertical boiling two-phase upward flow in a narrow annular channel. Nucl. Eng. Des. 217, 81-90], we reported that the disturbance wave has a significant effect on dryout and burnout occurrence and that a spacer greatly affects the behavior of the liquid film downstream of the spacer. In the present study, we examined in detail the influences of a spacer on the heat transfer and film thickness characteristics downstream of the spacer by considering the result in steam-water and air-water systems. The main results are summarized as follows: (1)The spacer averages the liquid film in the disturbance wave flow. As a result, dryout tends not to occur downstream of the spacer. This means that large temperature increases do not occur there. However, traces of disturbance waves remain, even if the disturbance waves are averaged by the spacer. (2)There is a high probability that the location at which burnout occurs is upstream of the downstream spacer, irrespective of the spacer spacing. (3)The newly proposed burnout occurrence model can explain the phenomena that burnout does occur upstream of the downstream spacer, even if the liquid film thickness tFm is approximately the same before and behind the spacer

    通过建立状态空间模型,运用卡尔曼滤波解法,并使用系统聚类法将我国各省区按照房价高低重新划分为三个区域,比较分析了两类货币政策工具对不同区域房价的动态影响特点。实证结果表明:以M2为代表的数量工具和以利率为代表的价格工具对各区域房价的影响力都在不断扩大,但是前者的影响力显著强于后者;数量工具的"分层效应"更明显,即区域差异性更大,对房价越高的地区影响力越大。因此要根据两类货币政策工具对区域房价影响效果的特点,在不同时期按照对房地产市场调控的需要,调整和优化货币政策的工具组合,才能达到我国房地产市场的调控目标。%by establishing a State--space model and applying the Caiman Filter calculation, and using system clustering method to classify China's provinces into 3 groups in accordance with the housing price level, so that to make a comparative analysis of effects of the two types of monetary policy tools towards different areas. The empirical results show that both the quantitative tools represented by M2 and the pricing tools represented by real rate, have increasing influence to regional housing prices, but the former influence is stronger than the latter; The regional differences of quantitative tools is much greater, which means the higher the housing prices in the region and the larger the influence will become. Therefore, according to these characteristics of the two types of monetary policy tools, we shall adjust and optimize the combination of monetary policy tools in different periods according to the requirements of the regulation of the real estate market, so that to achieve our regulation aim towards the real estate market.

  20. A check-list of the pentastomid parasites of crocodilians and freshwater chelonians

    2006-09-01

    Full Text Available Based on published records and own data a summary is given of the geographical distribution of the currently known species of pentastomid parasites infecting crocodiles and alligators, as well as freshwater chelonians. A brief generic diagnosis is provided for each genus. Fourteen out of the currently 23 living crocodilian species have been recorded as being host to one or more pentastomes. Out of the 32 pentastome species six are considered species inquirendae. Presently, six genera of crocodilian pentastomes, Agema, Alofia, Leiperia, Sebekia, Selfia and Subtriquetra are recognized. African crocodiles harbour eight pentastome species, six of which have been recorded from the Nile crocodile, Crocodylus niloticus. Three species belong to the genus Sebekia, Alofia being represented by two and Leiperia by only one species. Two species, Alofia parva and Agema silvaepalustris, occur in the dwarf crocodile, Osteolaemus tetraspis, and the slender-snouted crocodile, Crocodylus cataphractus, exclusively, but a single Sebekia species is shared with the Nile crocodile. The genus Agema is endemic to the African region. Infective stages of the pentastome Sub triquetra rileyi, thought to utilize Nile crocodiles as final hosts, have been recovered only from fishes. The largest number of pentastome species is found in the Australasian region. Of these, the Indo-Pacific croc odile, Crocodylus porosus, harbours seven, representing the genera Alofia, Sebekia, Lei peria and Selfia. Selfia is exclusive to the latter host. The genus Subtriquetra has been reported from "Indian crocodiles", a term possibly referring to either Crocodylus palustris, Crocodylus porosus or Gavialis gangeticus. Ten species of pentastomes parasitizing the crocodilian genera Alligator, Caiman, Crocodylus and Melanosuchus have been recorded from the Neotropical region including the southern states of the North American continent. The two most wide-spread pentastome genera, Alofia and Sebekia

    The food-web structure and seasonality of the dominant taxa of benthopelagic megafauna (fishes and decapods) on the middle slope of the Catalan Sea (Balearic Basin, NW Mediterranean) were investigated using the carbon and nitrogen stable isotope ratios of 29 species. Macrofauna (infauna, suprabenthos and zooplankton) were also analysed as potential prey. Samples were collected on a seasonal basis from 600 to 1000 m depth between February 2007 and February 2008. The fishes and decapods were classified into feeding groups based on the literature: benthic feeders (including suprabenthos) and zooplankton feeders, the latter further separated into migratory and non-migratory species. Decapods exhibited depleted δ15N and enriched δ13C compared to fishes. Annual mean δ13C of fishes ranged from - 19.15‰ (Arctozenus risso) to - 16.65‰ (Phycis blennoides) and of δ15N from 7.27‰ (Lampanyctus crocodilus) to 11.31‰ (Nezumia aequalis). Annual mean values of δ13C of decapods were from - 18.94‰ (Sergestes arcticus) to - 14.78‰ (Pontophilus norvegicus), and of δ15N from 6.36‰ (Sergia robusta) to 9.72‰ (Paromola cuvieri). Stable isotopes distinguished well amongst the 3 feeding guilds established a priori, pointing to high levels of resource partitioning in deep-sea communities. The trophic structure of the community was a function of the position of predators along the benthic-pelagic gradient, with benthic feeders isotopically enriched relative to pelagic feeders. This difference allowed the identification of two food webs based on pelagic versus benthic consumption. Prey and predator sizes were also important in structuring the community. The most generalised seasonal pattern was δ13C depletion from winter to spring and summer, especially amongst migratory macroplankton feeders. This suggests greater consumption of pelagic prey, likely related with increases in pelagic production or with ontogenic migrations of organisms from mid-water to the Benthic

    Children with sensorineural hearing loss may (re)gain hearing with a cochlear implant-a device that transforms sounds into electric pulses and bypasses the dysfunctioning inner ear by stimulating the auditory nerve directly with an electrode array. Many implanted children master the acquisition of spoken language successfully, yet we still have little knowledge of the actual input they receive with the implant and specifically which language sensitive cues they hear. This would be important however, both for understanding the flexibility of the auditory system when presented with stimuli after a (life-) long phase of deprivation and for planning therapeutic intervention. In rhythmic languages the general stress pattern conveys important information about word boundaries. Infant language acquisition relies on such cues and can be severely hampered when this information is missing, as seen for dyslexic children and children with specific language impairment. Here we ask whether children with a cochlear implant perceive differences in stress patterns during their language acquisition phase and if they do, whether it is present directly following implant stimulation or if and how much time is needed for the auditory system to adapt to the new sensory modality. We performed a longitudinal ERP study, testing in bimonthly intervals the stress pattern perception of 17 young hearing impaired children (age range: 9-50 months; mean: 22 months) during their first 6 months of implant use. An additional session before the implantation served as control baseline. During a session they passively listened to an oddball paradigm featuring the disyllable "baba," which was stressed either on the first or second syllable (trochaic vs. iambic stress pattern). A group of age-matched normal hearing children participated as controls. Our results show, that within the first 6 months of implant use the implanted children develop a negative mismatch response for iambic but not for trochaic

    Full Text Available Abstract Background homB encodes a Helicobacter pylori outer membrane protein. This gene was previously associated with peptic ulcer disease (PUD and was shown to induce activation of interleukin-8 secretion in vitro, as well as contributing to bacterial adherence. Its 90%-similar gene, homA, was previously correlated with gastritis. The present study aimed to evaluate the gastric disease association with homB and homA, as well as with the H. pylori virulence factors cagA, babA and vacA, in 415 H. pylori strains isolated from patients from East Asian and Western countries. The correlation among these genotypes was also evaluated. Results Both homB and homA genes were heterogeneously distributed worldwide, with a marked difference between East Asian and Western strains. In Western strains (n = 234, 124 PUD and 110 non-ulcer dyspepsia (NUD, homB, cagA and vacA s1 were all significantly associated with PUD (p = 0.025, p = 0.014, p = 0.039, respectively, and homA was closely correlated with NUD (p = 0.072. In East Asian strains (n = 138, 73 PUD and 65 NUD, homB was found more frequently than homA, and none of these genes was associated with the clinical outcome. Overall, homB was associated with the presence of cagA (p = 0.043 and vacA s1 (p homA was found more frequently in cagA-negative (p = 0.062 and vacA s2 (p Polymorphisms in homB and homA copy number were observed, with a clear geographical specificity, suggesting an involvement of these genes in host adaptation. A correlation between the homB two-copy genotype and PUD was also observed, emphasizing the role of homB in the virulence of the strain. Conclusion The global results suggest that homB and homA contribute to the determination of clinical outcome.

Alfred Wegener Institute Helmholtz Centre for Polar and Marine ResearchTristan da Cunha Island is one of the hot spots in the Atlantic Ocean. The discussion about its source have not reached consensus yet whether it is in shallow asthenosphere or deeper mantle, because of lack of the geophysical observations in the area. A marine magnetotelluric (MT) experiment was conducted together with seismological observations in the area in 2012-2013 by collaboration between Germany and Japan, in order to give further constraints on the physical state of the mantle beneath the area. A total of 26 seafloor stations were deployed around the Tristan da Cunha islands and available data were retrieved from 23 stations. The MT responses were estimated for those available sites. The detailed data processing will be presented by Chen et al. in this meeting. In this study, we report on the topographic effect on the observed MT responses. During the cruises for seafloor instruments deployment and recovery, detailed bathymetry data were collected around the stations by onboard multi-narrow beam echo sounding (MBES) system. We compiled the MBES data and ETOPO1 data to incorporate the local and regional topography. Then, we applied iterative topographic effect correction and one-dimensional (1-D) conductivity structure inversion. The MT responses of each station were simulated by three-dimensional (3-D) forward modeling. Preliminary results show the overall feature of the observed MT responses at some stations were qualitatively well explained by the seafloor topography included in the conductivity structure model over the 1-D mantle structure. An extreme example is the station near the Tristan da Cunha Island. The impedance phases varies ~300 degrees in

    The cores at hanging wall (C0004) and footwall (C0008) of mega splay fault are obtained in the Stage 1A of the Nankai Trough Seismogenic Zone Experiment during IODP Expeditions 316 (Kimura et al., 2008). The mega splay fault develops in the area where the coseismic slip (Ichinose et al., 2003) and tsunami source (Baba and Cumming, 2005) are reconstructed for the 1944 Tonankai earthquake. The X-ray computed tomography (X-CT) makes 3D image depending on X-ray attenuation coefficient that is a function of chemical composition and density of the target material. Whereas optical observation my not resolve small differences, emphasizing by the CT-scanner enables to find small difference in sediment composition and structures. The CT image has been taken for all cores during preliminary core processing. Episodic event deposits are found at uppermost core of hanging wall (C0004). The core sample is composed of un-consolidated silt clay and looks homogeneous in optical observation. The X-CT can show complex structure indicating some horizontal layers, scattered mud clasts and mud-filling burrows. The X-CT 3D observation can distinguish a mud clasts and mud-filling burrow. Because tubular burrow is formed by mud- eating worm or mollusks, the cross section area is constant along long axis. On the other hand, the cross section area changes along long axis in distorted shape mud clast. The mud clasts are intercalated between horizontal layers, indicating episodic event. At least five events are observed. The boundary of some mud- clasts are dim, may have suffered diffusion, and this implies very short transportation or in-situ formation. Thus, repeated mud clast deposit was not found at footwall of the fault (C0008). Strong seismic ground motion can shake surface soft sediment, and sediment suspensions were often observed after large earthquakes (Thunell et al., 1999; Itou et al., 2000; Seeber et al., 2007).

Dessa forma, sugere-se que, os óleos essenciais estudados podem ser utilizados no desenvolvimento de métodos alternativos de controle da antracnose em frutos de mamão, com destaque para os óleos de citronela e eucalipto. O óleo de citronela apresentou maior atividade contra o crescimento micelial de Colletotrichum gloeosporioides in vitro e deve ser testado, in vivo, na confirmação e comparação de sua eficiência em relação a produtos convencionais utilizados no controle dessa doença.

    An ATP-dependent glucokinase of the hyperthermophilic aerobic crenarchaeon Aeropyrum pernix was purified 230-fold to homogeneity. The enzyme is a monomeric protein with an apparent molecular mass of about 36 kDa. The apparent K(m) values for ATP and glucose (at 90 degrees C and pH 6.2) were 0.42 and 0.044 mM, respectively; the apparent V(max) was about 35 U/mg. The enzyme was specific for ATP as a phosphoryl donor, but showed a broad spectrum for phosphoryl acceptors: in addition to glucose, which showed the highest catalytic efficiency (k(cat)/K(m)), the enzyme also phosphorylates glucosamin, fructose, mannose, and 2-deoxyglucose. Divalent cations were required for maximal activity: Mg(2+), which was most effective, could partially be replaced with Co(2+), Mn(2+), and Ni(2+). The enzyme had a temperature optimum of at least 100 degrees C and showed significant thermostability up to 100 degrees C. The coding function of open reading frame (ORF) APE2091 (Y. Kawarabayasi, Y. Hino, H. Horikawa, S. Yamazaki, Y. Haikawa, K. Jin-no, M. Takahashi, M. Sekine, S. Baba, A. Ankai, H. Kosugi, A. Hosoyama, S. Fukui, Y. Nagai, K. Nishijima, H. Nakazawa, M. Takamiya, S. Masuda, T.

Kikuchi, DNA Res. 6:83-101, 145-152, 1999), previously annotated as gene glk, coding for ATP-glucokinase of A. pernix, was proved by functional expression in Escherichia coli. The purified recombinant ATP-dependent glucokinase showed a 5-kDa higher molecular mass on sodium dodecyl sulfate-polyacrylamide gel electrophoresis, but almost identical kinetic and thermostability properties in comparison to the native enzyme purified from A. pernix. N-terminal amino acid sequence of the native enzyme revealed that the translation start codon is a GTG 171 bp downstream of the annotated start codon of ORF APE2091. The amino acid sequence deduced from the truncated ORF APE2091 revealed sequence similarity to members of the ROK family, which

    The Chinese nationality contributes to over 5 million of 10% of the total population of Thailand and almost 35% of the total population of Malaysia. The aim of this paper is to summarize the nature and extent of Chinese influence on Thai and Malay culture. Migration of Chinese to southeast Asia dates back 2000 years; on the Malay peninsula, the first arrivals were in 1349. In Malaysia, arrivals began in the 15th century. The reasons were population pressure, floods, and famines. Social and political unrest also accounted for migration between 1855 and 1970. The Chinese in Malaysia are characterized as having a lower population growth rate than Malays and an abnormal sex ratio of 1000:930 in 1957, but severe ratios of 8 men to 1 woman in the 1820s. Islam forbids intermarriages. The Chinese have benefited from improvement in health care and had a low birth rate of 25/1000 in 1980. Migration has traditionally been from south China, and included migrations from Fujian, Hakkas, Guangdong, Chaozhou, and Hainan. The Chinese have maintained their own culture among the Muslim population. In Thailand, migrations occurred during the 13th century, following the collapse of Nan-Chao in 1253, but are first recorded during the Ming dynasty at the end of the 16th century. There are larger numbers of Chinese in Thailand than Malaysia. Chinese assimilated and the current rate of annual growth is estimated at 2%. The sex ratio was 1.4:1 in the late 1940s. 50% of the Chinese live in Bangkok and central Thailand. Older traditions are still maintained in Bangkok. There is the Chaozhou opera on Chinese New Year's Day and marriage is still preferred within one's own dialect. After 1946, the Chinese were not permitted to receive their education in their native language. By the third generation, there is greater assimilation. The minority of minorities in Malaysia were the Baba, who spoke better Malay than other Chinese. In Thailand, the comparable minority is the Yunnan who do not belong

    HAMLET (Highly Automated Multimedia Light Enhanced Theatre) was the star performance at the recent finals of the `Young Engineer for Britain' competition, held at the Commonwealth Institute in London. This state-of-the-art computer-controlled theatre lighting system won the title `Young Engineers for Britain 1998' for David Kelnar, Jonathan Scott, Ramsay Waller and John Wyllie (all aged 16) from Merchiston Castle School, Edinburgh. HAMLET replaces conventional manually-operated controls with a special computer program, and should find use in the thousands of small theatres, schools and amateur drama productions that operate with limited resources and without specialist expertise. The four students received a £2500 prize between them, along with £2500 for their school, and in addition they were invited to spend a special day with the Royal Engineers. A project designed to improve car locking systems enabled Ian Robinson of Durham University to take the `Working in industry award' worth £1000. He was also given the opportunity of a day at sea with the Royal Navy. Other prizewinners with their projects included: Jun Baba of Bloxham School, Banbury (a cardboard armchair which converts into a desk and chair); Kobika Sritharan and Gemma Hancock, Bancroft's School, Essex (a rain warning system for a washing line); and Alistair Clarke, Sam James and Ruth Jenkins, Bishop of Llandaff High School, Cardiff (a mechanism to open and close the retractable roof of the Millennium Stadium in Cardiff). The two principal national sponsors of the competition, which is organized by the Engineering Council, are Lloyd's Register and GEC. Industrial companies, professional engineering institutions and educational bodies also provided national and regional prizes and support. During this year's finals, various additional activities took place, allowing the students to surf the Internet and navigate individual engineering websites on a network of computers.

Mainly based on semi-directing talks and archives, the article sought to analyze the key elements of this structuring: the project of Departmental Mining Master Plan (SDOM and several initiatives dedicated to improve the mining operators’ practices. However, this evolution of which pace is variously appreciated, is not done without disagreements, insofar as it puts in relief antagonisms between the stakeholders (mainly territorial collectivities and the central level, operators mining and environmentalists. Indeed, these antagonisms were revealed, on the one hand, during the Camp Caiman case (which involved Iamgold, and on the other hand during the development process of the SDOM itself. Related problems such as local claims of mining governance and the illegal artisanal and small scale gold mining draw up future prospects rather mitigated for the sector.

  18. Calcium isotopes in fossil bones and teeth — Diagenetic versus biogenic origin

    We present the first systematic study of Ca isotopes ( δ44/40Ca) in Late Triassic to Late Cretaceous dinosaur bones and teeth (enamel and dentin) from sympatric herbivorous and carnivorous dinosaurs. The samples derive from five different localities, and data from embedding sediments are also presented. Additional δ44/40Ca in skeletal tissues from modern reptiles and birds (avian dinosaurs) were measured for comparison in order to examine whether the original Ca isotopic composition in dinosaur skeletal apatite was preserved or might have changed during the diagenesis and fossilization process. δ44/40Ca of fossil skeletal tissues range from -1.62‰ ( Tyrannosaurus rex enamel) to +1.08‰ ( Brachiosaurus brancai bone), while values in modern archosaur bones and teeth range from -1.63‰ (caiman enamel) to -0.37‰ (ostrich bone). The average δ44/40Ca of the three types of fossil skeletal tissue analyzed - bone, dentin and enamel - show some systematic differences: while δ44/40Ca in bone exhibits the highest values, while δ44/40Ca in enamel has the lowest values, and dentin δ44/40Ca falls in between. Values of δ44/40Ca in the remains of herbivorous dinosaurs (0.1-1.1‰) are generally higher than those of bones of modern mammalian herbivores (-2.6‰ to -0.8‰) and from modern herbivorous archosaurs, which exhibit intermediate δ44/40Ca (-0.8‰ to -0.4‰). These systematic isotopic shifts may reflect physiological differences between dinosaurs, mammals and reptiles representing different taxonomic groups of vertebrates. Systematic offsets in skeletal apatite δ44/40Ca between herbivorous and carnivorous dinosaurs are not obvious, indicating a lack of a clear-cut Trophic Level Effect (TLE) shift between herbivores and carnivores in dinosaurs. This observation can be explained if the carnivorous dinosaurs in this study fed mainly on soft tissues from their prey and did not ingest hard (calcified) tissue to much extent. The most striking indication that the

    The polymorphism of MHC class Ⅱ B gene in 14 Chinese alligators was analyzed, which came from three different areas: a wild population from Xuancheng, Anhui, a captive population from Changxing, Zhejiang, and a captive population from Anhui Research Center for Reproduction of Chinese Alligators. The gene fragment was amplified using a pair of specific primers designed from the MHC gene sequence of the spectacled caiman. A total of 34 sequence haplotypes of exon 3 were detected in the sampled Chinese alligators. The numbers of haplotypes of the 3 Chinese alligator populations were 15, 10, and 9, respectively. The overall estimation of the MHC polymorphism in the Chinese alligator population was higher than those in mammals and in cyprinid fish. The rates of nonsynonymous substitutions (dN) occurred at a significantly lower frequency than that of synonymous substitutions (ds), which were not consistent with the common rule. This result might suggest that the polymorphism of exon 3 seemed not to be maintained by the balancing selection. The neutrality test of Tajima excluded the null hypothesis that the polymorphism of exon 3 was generated by a random drift, and the fact that D = -0.401 indicated an excess of rare mutations in the Chinese alligator.The nucleotide diversity of the sequences and the phylogenetic relations were also analyzed, and the results suggested that there was no significant difference in genetic diversity among the 3 populations of Chinese alligator.%分析了取自安徽宣城野生种群、安徽省扬子鳄繁殖研究中心和浙江长兴养殖种群的14条扬子鳄MHCⅡ类B基因第3外元的多态性.在这些扬子鳄样本中共检测到34个单倍型,每个亚种群内检测到的单倍型数量分别为15,9和10个,与其他一些动物如哺乳动物和鲤科鱼类相比,扬子鳄MHC Ⅱ类B基因第3外元多态性较高.另外,非同义替换率显著小于同义替换率,这可能表明扬子鳄种群MHC Ⅱ类B基因第3外元

We also examine the geochemical and mineralogical bone mineralization of extant archosaurs (caiman and bird for comparison. Diagenetic processes have modified the original chemical composition of the studied fragments of bones, as well as its crystallinity, which increases in the fossil samples. In recent bones, hydroxyapatite results the main mineral constituent, while in fossils is fluorapatite. We found two types of mineralogical arrangements: one group exhibiting the spongy structure completely collapsed forming breccias of bone fragments, and a second group with well preserved spongy structure but substituted by calcium carbonate. Calcite is the most abundant authigenic mineral infilling pores and fissures of the fossilized remains. The presence of pyrite in bone cavities suggests an early burial stage under euxinic conditions of a reductor environment. The biostratinomic and fossildiagenetic alterations allow us to conclude that the remains have two distinct taphonomic histories, and that the association undergone taphonomical resedimentation.Las diferentes técnicas utilizadas (difracción de rayos X, microscopio petrográfico, microscopio electrónico de barrido y microsonda electrónica en el estudio de los restos óseos atribuidos a un ornitópodo del yacimiento Buenache de la Sierra (Baremiense superior, Formación La Huérguina han permitido caracterizar los procesos diagenéticos.

    Rabies, a disease of antiquity continues to be a major public health problem in India. Multiple factors contribute to high mortality and morbidity due to animal bites. An effective strategy for control of rabies takes into account the epidemiology of animal bites, rabies and factors influencing post exposure treatment. The study was carried out as a part of Agreement for Performance of Work (APW) from World Health Organization (WHO) during the period April 2001 to September 2002. Two sets of proformae were developed and used after field testing to interview cases of animal bites and get retrospective information about rabies cases. The study was carried out at six selected centres across the country viz. Delhi, Hyderabad, Raipur, Jamnagar, Coonoor and Rajahmundry and was co-ordinated by National Institute of Communicable Diseases (NICD), Delhi. The officials engaged in the study work were thoroughly trained in the study methodology before the start of the study itself. To maintain quality and uniformity supervisory checks were done during the survey. A total of 1357 fresh animal bite victims were interviewed (exit interview) from the anti-rabies centres (ARCs). Dog bites caused maximum morbidity (92%). Second most common biting animal was monkey (3.2%), followed by cat (1.8%), fox (0.4%) etc. Most bites (64.3%) were unprovoked bites by stray (64.7%) animals. In this study 72.4% animal bite victims were males and 47.5% were children in age group of 2-18 years. 63% had Category III exposure as per the WHO classification. Before coming to ARCs 58.5% people had washed the wound with water/soap or water alone. Some of the bite victims (10.8%) had also applied chillies, salt, turmeric powder, lime, snuff powder, paste of leaves, acid, ash given by Peer Baba (magician) etc. These practices varied from one region to another. The practice of wound washing at the ARC which is an important component of animal bite management was being practiced at only one of the six centres

    The eastern Mediterranean region is one of the most promising geothermal areas, with more than 250 geothermal fields discovered in Turkey (Parlaktuna, 2013), in a region of active tectonics and volcanism. Although the potential of these deep geothermal resources has not been systematically investigated yet, the geothermal activity of the western Turkey area is the most recent signature of the high heat flow (120-140 mW/m²; Aydin, 2005, from Teczan, 1995). Based on Turkish data, 2084 MWt are being utilized for direct applications and most of the energy originates from the Menderes Massif (Baba et al., 2015). This large-scale thermal anomaly at the surface is correlated to a long wavelength east-west increase of surface heat flow that could reflect the thermal state of Aegean subduction zone at depth. In order to better understand and characterize the possible connections between large-scale mantle dynamics and surface processes in space and time, we study the structure and thermal evolution of the Menderes Massif. Both the acceleration of the Aegean extension in the Middle Miocene and the recent escape of Anatolia have been proposed to result from several slab tearing events, the first one being located below western Turkey and the Eastern Aegean Sea. These events have triggered the formation of metamorphic complexes with contrasted exhumation P-T paths. While the extension in the Aegean domain is well-characterized with high-temperature domes in the center and east, the succession of several metamorphic events in the Menderes Massif and their significance in terms of geodynamics is still debated. Hence, the exhumation history is key to understanding the temporal and spatial distribution of the thermal signature of the Hellenic slab and its tearing/detachment. The Menderes Massif displays a large variety of metamorphic facies, from the Barrovian type metamorphism in the Eocene (the Main Menderes Metamorphism) to the coeval (?) HP-LT metamorphism on the southernmost

His father, Dövletmemmet Azadi (1700-1760, is one of the prominent representatives of Turkmen literature of the 18th century. Mahtumkulu was a poet and social leader who was not indifferent to the social problems of his era and tried to lead and give hope to his society. The poems of Mahtumkulu cover all aspects of Turkmen way of life. He was the voice of his people. Turkmen union, Turkmen spirit and consciousness, religion and Sufism, the comparison of good person and bad person, criticism of the individual and society, social justice, love, bad habits, education, helpfulness, and advice were the main themes of his poems. In this study, Mahtumkulu’s approach to the society and individuals, who make the society, will be addressed through his critical poems.Türkmen edebiyatının en büyük şairi sayılan Mahtumkulu 1724 yılında doğmuş, 1807 yılında da vefat etmiştir.

    Many infrastructure networks interact with and depend on each other to provide proper functionality. The interde-pendence between networks has catastrophic effects on their robustness. Events taking place in one system can propagate to any other coupled system. Recently, great efforts have been dedicated to the research on how the coupled pattern between two networks affects the robustness of interdependent networks. However, how to dynamically construct the links between two interdependent networks to obtain stronger robustness is rarely studied. To fill this gap, a global homogenizing coupled pattern between two scale-free networks is proposed in this paper. Making the final degrees of nodes distributed evenly is the principle for building the dependency links, which has the following two merits. First, the system robustness against random failure is enhanced by compressing the broadness of degree distribution. Second, the system invulnerability against targeted attack is improved by avoiding dependence on high-degree nodes. In order to better investigate its efficiency on improving the robustness of coupled networks against cascading failures, we adopt other four kinds of coupled patterns to make a comparative analysis, i.e., the assortative link (AL), the disassortative link (DL), the random link (RL) and global random link (GRL). We construct the BA-BA interdependent networks with the above 5 coupled patterns respectively. After applying targeted attacks and random failures to the networks, we use the ratio of giant component size after cascades to initial network size to measure the robustness of the coupled networks. It is numerically found that the interdependent network based on global homogenizing coupled pattern shows the strongest robustness under targeted attacks or random failures. The global homogenizing coupled pattern is more efficient to avoid the cascading propagation under targeted attack than random failure. Finally, the reasonable expla

Vroedvroue verskaf moeder-gesentreerde sorg, maar dit is nogtans belangrik dat hulle onthou om die vaders te betrek in die besluitneming en hulle rol, verwagtinge en behoeftes te erken omdat die geboorte van ‘n kind een van die belangrikste gebeurtenisse in hulle lewens is. Die studie het gefokus op vaders se verwagtinge van die sorg wat verskaf word aan moeders tydens kraam. ‘n Kwalitatiewe, eksploratiewe, beskrywende en kontekstuele navorsingsontwerp is gebruik. Data is ingesamel deur in-diepte onderhoude met vaders te voer oor die sorg wat aan hul vroue of metgeselle tydens die kraamproses verskaf word deur vroedvroue. Data is daarna geanaliseer deur ‘n oop beskrywende metode te gebruik wat toepaslik is vir kwalitatiewe navorsing. Die resultate van die onderhoude is vervolgens geposisioneer binne ‘n holistiese, gesondheids-bevorderende teorie wat verwys na liggaam, psige en gees. Die resultate toon dat gemak en ondersteuning die twee hoofkategorieë is wat verskaf moet word deur vroedvroue aan moeders tydens die kraamproses. Die ander kategorieë wat aangedui word in die resultate, is dat vroedvroue hulle onderlinge kommunikasievaardighede moet verbeter, asook hul kommunikasie met die moeders en vaders indien laasgenoemde beskikbaar is. Die vaders het van vroedvroue verwag om hulle aan te moedig om moeders by te staan tydens die kraamproses en om binding tussen vader, moeder en baba aan te moedig.

Erken dönemde çocuğun gelişiminde, benlik ve kişiliğin sağlam temeller üzerine kurulmasında ve çocuğun haklarını yaşayarak öğrenmesinde ailenin sunduğu fırsatlar son derece önemlidir. Bu araştırmada, 5-6 yaş aralığında çocuklara sahip ebeveynlerin çocuk haklarına ilişkin görüşlerini, çocuk hakları eğitimi uygulamalarını ve uygulamalarında karşılaştıkları sorunları ortaya çıkarmak amaçlanmıştır. Araştırmaya, Milli Eğitim Bakanlığı’na bağlı tam gün eğitim yapan bağımsız anaokullarında bulunan toplam 20 sınıfın her birinden gönüllü 15’i anne 5’i baba olmak üzere toplam 20 ebeveyn katılmıştır. Araştırma, nitel araştırma yöntemlerinden yarı-yapılandırılmış görüşme tekniğiyle gerçekleştirilmiştir. Elde edilen verilerinin çözümlenmesinde, betimsel analizden yararlanılmıştır. Araştırma sonucunda, ebeveynler görüşlerini ifade etme, seçme ve karar verme, kendine ve başkalarına zarar vermediği sürece istediklerini yapabilme haklarından söz etmekle birlikte, çocuk hakları konusunu yeterince bilmedikleri ve bilinçlendirme gereksinimi içinde oldukları görülmüştür. Ebeveynlerin, evde çocuk hakları eğitimine yönelik olarak gerçekleştirilen uygulamalarda, çocuklarla konuşma ve örnekler vererek anlatma, aile ortamında yaparak yaşayarak öğrenme ve model olma yaklaşımlarını kullandığı ortaya çıkmıştır. Araştırma sonuçlarına dayalı olarak, okulöncesi eğitimde aile katılımlı çocuk hakları eğitim programlarının geliştirilmesi ve yaygınlaştırılması önerilebilir.

Child abuse covers all kinds of attitudes and neglects that affect and limit children physical and emotional development by the parents or child careers. Child abuse affects the children’s emotional and physical development negatively. A child whose emotional development is disturbed lives with very serious psychological and communication problems as well as decrease of life quality. Child abuse can be a learned and passed through cognitive behavior. It is known that the perpetrators of child abuse are also victims of child abuse in their own childhoods. Child abuse can be one kind of cycle of violence. Today’s victims of child abuse have a tendency to become the perpetrators of tomorrow’s child of abuse. Child abuse can be prevented by the collective efforts of the whole community. Establishing a collective consciousness about the harms of the child abuse can become the initial step of fighting against child abuse. The considerable success can be reached when effective public policies, which attribute to collective consciousness addressing different fractions of the society are established. ÖzetÇocukların fiziksel, duygusal ve cinsel yönden istismar ve ihmal edilmesi tüm toplumlarda yaygın görülen bir sosyal ve sağlık sorunudur.

    In their pioneering work, the geophysicists A. Brekke and A. Egeland (1983) collected beliefs of different peoples, associated with northern lights. Our analyses of this collection show that these beliefs are mainly related to the mythological idea of ``abnormal'' deads (dead, childless old maids in Finnish beliefs; killed people; spirits dangerous to children). We find similar motifs in Slavic fairy tales about the ``Thrice-Nine Land,'' regarded as the other world in folkloric studies (in the Land where mobile and agitated warlike girls live, whose Head Girl is characterized by the words ``white snow, pretty light, the prettiest in the World,'' but whose name ``Mariya Morevna'' refers to the word ``mort''; where a river flows with its banks covered by human bones; where the witch Baba-Yaga dwells, being extremely dangerous for children). Moreover, it can be noted that similar narrative fabulous myths deal with the concept of auroral oval northern lights, since some specific features of the natural auroral forms are mentioned there, with their particular spatial orientations (to the North or West). This resembles the manner in which Ancient Greek myths describe the real properties of the heavenly phenomena in a mythological language. It is interesting that myths on the high-latitude northern lights spread even to the South of Europe (and, might be, to India and Iran). This fact can be understood in view of the following. It has been established that, during the late glacial epoch, the environmental and cultural conditions were similar over the area from Pyrenean to the Ural Mountains; the pattern of hunters' settlements outlined the glacial sheet from the outside. Relics of the hunters' beliefs can now be found in Arctic, where the environment and lifestyle remain nearly unchanged. The ethnographer Yu.B. Simchenko (1976) has reconstructed the most archaic Arctic myths. According to them, the World of dead is associated with the world of ice governed by the ``Ice

    biological, medical and life science applications or sensors and sensing systems. Selected papers or special features in recent issues of MST attest to this development [1-3]. In parallel with these new fields, board members have always kept their eye on the other journal topics. Many papers published in MST have been downloaded very often and highly cited. This shows the acceptance and reputation of MST. Thanks to the activity of all board members over the last ten years MST has published a number of excellent review articles. This has strengthened the prestige of MST. A new series of articles was introduced under the banner of 'Perspectives' in 2008. They highlight milestones in a selected field and indicate some future challenges from the point of view of the author [4]. In summary, it can be stated that MST is on a good path. This was created thanks to the activity of all members of the Editorial Board. In recent years we have enlarged this board with well known scientists from universities and industry from all over the world. This will ensure a continuously positive development of MST. As outgoing Editor-in-Chief, I can say that I have found my task fascinating and I have enjoyed it very much. I have learned a lot in this time because I have come into close contact with a large number of scientists from a vast spectrum of technical areas and parts of our world. My special gratitude is dedicated to all the Editorial Board members of the last ten years and especially to Sharon D'Souza from IOPP.

    Kırgız Türklerinin, başta Manas Destanı olmak üzere bütün destanlarında, kahramanların yaptıkları mücadeleler aksettirilmiştir. Kırgız destanlarında genellikle, bahadır bir babanın mücadelesini bahadır oğlu ya da bahadır kızı devam ettirerek vatanını düşmanlardan korumaktadır. Böylelikle destan, genellikle birden fazla daireden oluşmaktadır. Bu tür destanların başında Manas gelmektedir. Manas’ın mücadelesini, Manas öldükten sonra oğlu Semetey, ondan sonra da torunu Seytek devam ettirir. Er Töştük Destanının ikinci dairesini ise Coodarbeşim Destanı teşkil etmektedir. Destanda Coodarbeşim, babası Er Töştük’ün bir zamanlar yapamadığı işleri yapmak üzere yola çıkar ve çeşitli maceralar yaşayarak evine, doğduğu yere döner.Er Töştük Destan dairesinin ikinci halkası olması nedeniyle Kırgız Destan Geleneği içinde ayrı bir yere sahip olan Coodarbeşim Destanı, Kırgız Türklerinin önemli destanlarından biri olarak halk arasında hem masal (cöö comok hem destan şeklinde söylenip gelmiştir. Bu çalışmada Coodarbeşim Destanının Oruzbay Urmanbetov, Abdıkerim Asan ve Kalça Surançiyev’in varyantları üzerinde durulmuştur.

For these studies, microbeams represent an essential tool, considering that in space each cell in the human body will not experience more than one heavy-ion traversal. Both NASA and ESA are investing important resources in ground-based space radiation research programs, to reduce risk uncertainty and to develop countermeasures. For both cancer therapy and space radiation protection a better understanding of the effects of energetic heavy ions is needed. Physics should be improved, especially the measurements of nuclear fragmentation cross-sections, and the transport calculations. Biological effects need to be studied in greater detail, and clearly only understanding the mechanisms of heavy-ion induced biological damage will reduce the uncertainty on late effects in humans. This focus issue of New Journal of Physics aims to provide the state-of-the-art of the biophysics of energetic heavy ions and to highlight the areas where more research is urgently needed for therapy and the space program.

    . Bu sosyal becerilerden birisi de iletişim becerisidir. Daha küçük yaşlardan itibaren verilecek beceri eğitimi ile öğrencilerimize iletişim becerileri kazandırarak içinde yaşadığı toplumda mutlu, üretken ve etkili bir insan olmasını sağlayabiliriz. Bunun için öğrencilerimizin iletişim becerileri üzerinde etkili olabilecek faktörlerin bilinmesi önem arz etmektedir. Bu araştırmanın amacı da ilköğretim öğrencilerinin iletişim becerileri üzerinde etkili olan faktörleri ortaya koymaktır. Bu amaç doğrultusunda Ersanlı ve Balcı (1998 tarafından geliştirilen “İletişim Becerileri Envanteri" Ankara ve Kırşehir'de bulunan iki ilköğretim okulunun 6., 7. ve 8. sınıflarında öğrenim gören 373 öğrenciye uygulanmıştır. Verilerin analizi SPSS 15 istatistik programı kullanılarak yapılmıştır. Verilerin analizinde; betimsel istatistik, ilişkisiz örneklemler için t-testi, tek yönlü varyans analizi (ANOVA kullanılmıştır. Araştırma sonucunda ilköğretim öğrencilerinin iletişim becerileri üzerinde öğrencilerin yaşadıkları ilin, cinsiyetin, okul öncesi eğitimin, anne-baba eğitim durumunun ve sınıf düzeyinin etkili olduğu görülmüştür. Ayrıca öğrencilerin, Türkçe dersinden aldıkları not, okudukları kitap sayısı, günlük kitap okuma süreleri arttıkça iletişim becerileri artarken günlük televizyon izleme ve bilgisayar kullanma süreleri arttıkça iletişim becerileri azalmaktadır. Bu sonuçlar doğrultusunda öğretmenlerin derslerdeöğrencilerin kendilerini daha iyi ifade edebilecekleri ortamları oluşturmaları, öğrencilerin daha fazla kitap okuması için teşvik edilmesi, çocukların okul öncesi eğitime mümkün olduğunca erken başlatılması ve ebeveynlerin çocuklarının TV ve bilgisayar başında çok fazla zaman geçirmelerine izin verilmemeleri önerilmiştir.

    teaching profession and the attitude towards theprofession. Öğretmen öz-yeterlik inancı öğretmenlerin mesleki başarısını önemli ölçüde etkileyen etmenler arasındadır. Öğretmen öz-yeterliği beden eğitimi ve spor öğretmenleri için de en az diğer alanlar kadar önemlidir çünkü genel eğitimin tamamlayıcısı ve ayrılmaz bir parçası olan beden eğitimi aynı zamanda kişiliğin de eğitimidir. Bir öğretmenin sahip olduğu yeterliklerin oluşturulmasında en belirleyici rolü öğretmenin hizmet öncesi eğitimi oynamaktadır. Bu araştırmayla, beden eğitimi ve spor öğretmeni adaylarının öz-yeterlik inanç düzeylerini bazı değişkenlere göre incelemek ve öğretmen öz-yeterlik inançlarıyla öğretmenlik mesleğine ilişkin tutumlar arasındaki ilişkiyi ortaya koymak amaçlanmaktadır. Araştırmanın örneklemini, farklı coğrafi bölgelerden 10 devlet üniversitesinde, 1. ve 4. sınıfta öğrenim gören toplam 558 beden eğitimi ve spor öğretmeni adayı oluşturmaktadır. Öğretmen adaylarına kişisel bilgi formu, öğretmenlik mesleğine ilişkin öz-yeterlik ölçeği ve öğretmenlik mesleğine yönelik tutum ölçeği uygulanmıştır. Bulgulara göre, beden eğitimi ve spor öğretmeni adaylarının öz-yeterlik inançlarının “oldukça yeterli” düzeyde olduğu tespit edilmiştir. Cinsiyete, sınıf düzeyine, anne eğitim düzeyine, spor branşının türüne göre öğretmen adaylarının öz-yeterlik inançlarının farklılaşmadığı, ancak bölümü isteyerek seçme, baba eğitim düzeyi, düzenli spor yapma durumlarına göre anlamlı farklılıklar olduğu tespit edilmiştir. Öğretmenlik mesleğine ilişkin öz-yeterlik inancıyla, mesleğe ilişkin tutum arasında ise orta düzeyde pozitif bir ilişki olduğu görülmüştür.

    -culture on thisevent with together ‘Devshirme’. ‘Her çocuk, fıtrat üzere doğar; sonra onu ana-babası Yahudileştirir, Hıristiyanlaştırır veya Mecusîleştirir’ hadisi, temel İslam bilimlerinde ‘fıtrat hadisi’ olarak bilinir. İslami literatürde, geçmişten günümüze, bu hadis hakkında çeşitli görüşler ortaya konmuştur. Fıtrat hadisinin, klasik hadis literatüründeki kaynakları ve hadis imamlarının bu hadise bakışları açısından daha çok ‘Çocuğun ölmesi halinde dinî ve hukukî durumunun ne olacağı?’ sorusu üzerinde durulmuştur. Ancak hadis bilginleri ve bazı interdisipliner İslam âlimleri, fıtrat’ın ‘insanlığın ortak dinî temeli’ olduğuna inanmaktadırlar. Bu görüşe bağlı olarak biz, fıtrat hadisi’nin Osmanlı’daki ‘devşirme’ hadisesiyle örtüştüğünü düşünüyoruz. Devşirme sisteminin, tarihi bir olgu olarak, Osmanlı’da gerçekleşen halini ele almak istiyoruz. Bu haliyle Osmanlı Devleti bu olguyu sistemleştirip kanun, tüzük ve yönetmeliği olan bir sistem haline koymadan önce dini yönünü hesaba kattığını; bu hadisteki ‘fıtrat gerçeği’nden hareket etmiş olabileceğini; güçlü kaslar ve çalışkan beyinler sayesinde özelde devletine genelde insanlığa hizmet ettiğini var sayıyoruz. O günün dünya devleti olan Osmanlı’dan bugünün dünya devleti ABD’ye baktığımızda, işleyiş ve yöntem farklı olsa da, birtakım paralellikler görmekteyiz. Farklı asırlarda, değişik coğrafyalarda, birbirine benzemeyen iki büyük medeniyetin ortaya koyduğu uygulamadaki benzerlik ve ulaştığı ortak nokta, eğitimin, başat belirleyici olduğu gerçeğidir. Bu makalenin amacı, sadece tarihî bir fenomeni dile getirmek değil; fıtratın anlamını, geçerliliğini bu tarihî olgudan hareketle yinelemektir. Makalemizde bu konuyu fıtrat yani insanın değişmeyen varlık yapısı ve eğitim-kültürün bu yapıya etkisini ‘devşirme’ olgusuyla

  14. Belirtili Ad Tamlamasında İyelik ve İlgi Eki Yanılgısı Delusion of possessive and genitif suffix in noun phrase and determinative noun phrase

    possesive suffix. İki veya daha fazla adın bir araya gelerek oluşturdukları anlamlı yapılara ad tamlaması denir. Türkçede tamlamayı oluşturan adlar aldıkları eklerin varlığı ve yokluğuna göre belirtili, belirtisiz ve takısız ad tamlaması şeklinde adlandırılırlar. Belirtili ad tamlamalarında ilk kelimeye eklenen ekin ilgi, ikinci kelimeye eklenen ekin ise iyelik eki olduğu varsayılır. Araştırmada bu varsayımın tersi bir tez savunulmuş ve araştırma sonucunda „iyelik eki‟ olarak bilinen ekin Türkçede aslında iyelik işlevinde olmadığı bu ekin kendisinden önceki kelimeyle ilgi kurduğu ve sahip olan kişi ya da nesne bilgisi verdiği kanısına varılmıştır. İyelik (sahiplik anlamını ise belirtili ad tamlamalarında ilk kelimeye eklenen ve „ilgi eki‟ olarak bilinen ekin verdiği tespit edilmiştir. Araştırma sonucunda eklerin varlığı ve yokluğu ile tamlamada kurdukları ilişki şöyle tespit edilmiştir:1. Belirtili ad tamlaması: İyelik ilişkisi söz konusudur: Giray’ın arabası gibi. Ayrıca bu tamlama öbeğinde iyelik ilişkisi sınırlı örnekte eksiltili bir anlatımla gerçekleşir: Bizim ev gibi.2. Belirtisiz ad tamlaması: Bir şeyin bir türünün adlandırmasıdır: Mevlana şekeri gibi.3. Takısız ad tamlaması: Bir şeyin adlandırması olup bazen de bir şeyin neden yapıldığı bilgisini verir: baba anne gibi.İyelik eklerinin birçok işlevi (parça-bütün ilişkisi gibi söz konusu olmakla birlikte öncelikli işlevi iyelik ilişkisi kurmaktır. Yukarıdaki sıralamadan da görüldüğü gibi bu ilişki yalnıza belirtili ad tamlamalarında söz konusudur. Bu doğrultuda belirtisiz ad tamlamasında yer alan tek ek iyelik değil, ilgi ekidir. Böylece iyelik ekinin yer almadığı belirtisiz ad tamlamalarında iyelik ilişkisi aramak yersizdir. Böylece belirtisiz ad tamlamasındaki eki iyelik eki olarak adlandırıp sonrasında “Bu tamlamada iyelik ilişkisi yoktur!” çelişkisine düşülmeyecektir.

    Purposive convenient sampling, as described by Babbie and Mouton (2002:166, was used in both phases of the study. All participants chose a gynaecologist as the primary care giver and delivered in various private hospitals in Johannesburg. Data were collected by means of an anonymous questionnaire, compiled from national and international literature, as well as personal interviews. Data from the questionnaires were analysed by hand. Descriptive statistics were applied. The interviews were analysed according to the descriptive analysis suggested by Tesch (in Creswell, 1994:155. Themes that emerged were clustered and coded. A co-coder, experienced in the field of qualitative research, assisted with the analysis of the transcripts of the interviews. A literature control was conducted to validate the findings. Ethical considerations were based on the DENOSA Ethical Standards for Nurse Researchers (1998:2.3.2–2.3.4. Themes and sub-themes were identified.

    Opsomming

    Ten spyte van die goed gedokumenteerde gesondheidsvoordele van borsvoeding en die aanbevelings van die Departement van Gesondheid dat vroue vir ongeveer die eerste ses weke tot een jaar uitsluitlik moet borsvoed, word gevind dat 'n groot aantal Suid-Afrikaanse vroue hul babas nie borsvoed nie, of slegs vir 'n kort tydperk borsvoed. Geen nasionale Suid-Afrikaanse statistiek is beskikbaar nie, maar 64% van moeders wat 'n babakliniek besoek het op die Wes Rand in Gauteng borsvoed steeds op ses weke, waarna die aantal borsvoedende moeders verminder tot minder as 20% op drie maande (Truter 2007. Verskeie studies het die houding van gesondheidspersoneel ten opsigte van borsvoeding bepaal, maar min is bekend oor die tipe inligting wat deur die mediese praktisyn aangebied word. Hierdie praktisyn het eerstehandse kontak met die kliente en mag inligting aanbied wat borsvoeding kan bevorder of belemmer. Die volgende vraag is dus geformuleer: Met betrekking tot borsvoeding

    ğrencilerin görüşlerine dayalı olarak betimlenmesi amaçlanmıştır. Bu araştırmayla, ilköğretim öğrencilerinin öğrenim hayatında karşılaştıkları tekerlemelere ilişkin görüşlerinin ne olduğu tespit edilmeye çalışılmıştır. Araştırma yöntemi olarak betimsel nitelikli tarama modelinde bir araştırma olup, 2011-2012 eğitim öğretim yılında Sivas ili evrenininden random yöntemiyle belirlenmiş üç ilköğretim Okulu’na devam eden 216 yedinci sınıf öğrencisi araştırmanın örneklemini oluşturmuştur. Öğrencilerin görüşlerini belirlemek üzere araştırmacı tarafından geliştirilen 20 maddelik anket veri toplama aracı olarak kullanılmıştır. Araştırma sonucunda şu sonuçlara ulaşılmıştır: Öğrencilerin çoğunluğu tekerlemelerin eğitim-öğretim sürecinde kullanımına yönelik olumlu görüş bildirmişlerdir. Kız öğrencilerin erkek öğrencilere göre tekerlemelerin Türkçe dil becerisine etkisine ilişkin daha olumlu görüş bildirdikleri saptanmıştır. Ayrıca anne ve baba eğitim düzeyi ile öğrencilerin görüşleri arasında pozitif korelasyon olduğu saptanmıştır. Diğer taraftan günlük hayatta tekerlemelerin kullanımına ilişkin aile içerisinde yeterli eğilimin olmadığı ve giderek unutulmaya yüz tutuğu bilinmektedir. Araştırma bulgularına dayanarak, tekerleme kültürünün eğitimsel ortama kazandırılması ile ilgili projeler yapılması, eğitim programındaki ders içeriklerinin tekerlemelerle ilişkilendirilerek işlenmesi gibi öneriler sıralanmıştır.

    ılının birinci döneminde Ankara ilinin Altındağ, Çankaya, Mamak ve Yenimahalle ilçelerinde bulunan liselerde uygulama yapılmıştır. Araştırma tarama yöntemine dayanmaktadır. Çalışma 3026 ortaöğretim öğrencisiyle gerçekleştirilmiştir. Ortaöğretim öğrencilerinin savaş ve barış konuları ile ilgili tutumları tespit edilmeye çalışılmıştır. Savaş ve barış tutum ölçeği 40 maddeden oluşmaktadır. Elde edilen veriler SPSS 15,0 paket programıyla değerlendirilmiştir. Araştırma sonuçları değerlendirildiğinde öğrencileri cinsiyet, savaş oyunu oynayıp oynamama ve bilgisayar oyunu oynayıp oynamama değişkenlerine göre farklıkları olduğu gözlenmiştir. Öğrenciler arasında en az farklılığın ise baba eğitim düzeyi ve sınıf düzeyi arasında olduğu görülmüştür.Ortaöğretim öğrencileri insanın savaşçılık özelliği ile doğduğu şeklindeki önermeye kararsız kalmıştır. Öğrenciler savaşların Tanrının takdiri olduğu görüşüneyse katılmamıştır. Ortaöğretim öğrencileri savaşların masum insanlara acı getirdiği ve savaşların başka savaşlara yol açtığı görüşünde olmuştur. Öğrencilere göre savaşı kazanan da savaşı kaybeden de savaşsın sonuçlarından acı çekmektedir. Ortaöğretim öğrencileri en büyük başarıların savaş meydanlarında kazanıldığı fikrine kararsız bir tutum sergilemiştir. Yine öğrenciler vatanseverlik gibi yüce duyguların savaş meydanlarında doğduğu fikrinde de kararsızdır. Buna karşı öğrenciler savaş kazanmak kadar barış kazanmanın da önemli olduğunu belirtmiştir. Öğrencilere göre barışa katkı sağlayan insanlar da kahraman ilan edilmelidir.Türkiye’de savaş ve barış kavramının hangi yaşlarda anlaşılabildiğine dair araştırmalar yapılmamıştır. Bu alanda araştırmalar alana katkı sağlayacaktır. Ayrıca savaşların niteliğine göre ayrılarak da araştırma yapılmasının önemli olduğu düşünülmektedir.

Therefore this research intends to examine what kind of changes in terms of structure and meaning And has undergone and/or been exposed to, in its editions published after the passing away of its author and in which part of the map developed by Holmes these changes have originated from. According to the theory suggested by Vermeer and Reiss, decision making bodies effective in reshaping the source text during the process of translation, will be tried to be described. Thus covering the period from the establishment of the Republic until today, a pilot study, in terms of the functions of patronage and ideologies in Turkish literature influencing the reshaping of a literary product will be presented. And; Türk edebiyatında “modern öykücülüğün babası” kabul edilen Ömer Seyfeddin’in (1884-1920 yazdığı öykülerden birinin adıdır. Bu öykünün, yazarın ölümünden sonraki baskıları incelendiğinde, kurgunun, yapı ve anlam açısından bozulduğu ve birbirinden oldukça farklı metinlere dönüştüğü görülür. Kaynak metin; yabancı bir kültürün diline çevrilmişçesine, biçim ve içerik açısından pek çok darbe almıştır. 20. yüz yılda, James Holmes (1924-1986 tarafından salt ve uygulamalı olmak üzere ikiye ayrılıp kendi içinde dallanıp budaklanan çeviribilimde, salt alandaki ürün-süreç-işlev odaklı betimleyici çalışmaların yanı sıra, içinde hem genel hem de araç-alan-düzey-metin türü-zaman-sorun ile sınırlandırılmış bölütlü çalışmaların bulunduğu kuramsal aşamalar yer alır.

    satisfação do profissional. O mesmo culmina na plenitude da realização profissional, em fazer o que gosta, não obstante os dissabores e conflitos no meio.CONCLUSÃODentro da pesquisa que nos propusemos a fazer atingimos o nosso objetivo, onde nossos dados confirmam que o maior sofrimento psíquico está diretamente ligado a organização do trabalho e não com a profissão. É notório que o orgulho de ser enfermeiro se conflita com uma condição de trabalho insatisfatória gerada também pela dificuldade de relacionamento interpessoal.Os resultados nos levam a essência da profissão, que se fundamenta no cuidar com amor ao próximo, com doação e humildade, pois a grande maioria dos entrevistados se consideram plenos, realizados e felizes em sua profissão. Assim, retomamos aos primórdios da profissão, cujas bases foram erigidas por Florence Nightingale galgadas pelo rol do altruísmo. REFERÊNCIAS1.     Baba V, Galaperin BL, Lituchy TR.
