    Cytophaga hutchinsonii, a member of the phylum Bacteroidetes, employs a novel collection of cell-associated proteins to digest crystalline cellulose. Other Bacteroidetes rely on cell surface proteins related to the starch utilization system (Sus) proteins SusC and SusD to bind oligosaccharides and import them across the outer membrane for further digestion. These bacteria typically produce dozens of SusC-like porins and SusD-like oligosaccharide-binding proteins to facilitate utilization of diverse polysaccharides. C. hutchinsonii specializes in cellulose digestion and its genome has only two susC-like genes and two susD-like genes. Single and multiple gene deletions were constructed to determine if the susC-like and susD-like genes have roles in cellulose utilization. A mutant lacking all susC-like and all susD-like genes digested cellulose and grew on cellulose as well as wild-type cells. Further, recombinantly expressed SusD-like proteins CHU_0547 and CHU_0554 failed to bind cellulose or ?-glucan hemicellulosic polysaccharides. The results suggest that the Bacteroidetes Sus paradigm for polysaccharide utilization may not apply to the cellulolytic bacterium C. hutchinsonii. PMID:25846333

    2010-01-01

    La historia de la migración México-Estados Unidos se caracteriza por una serie de periodos durante los cuales los patrones migratorios se transforman y evolucionan como respuesta a los cambios en la política migratoria de Estados Unidos. En la década de 1990 se dio uno de estos cambios, lo que provocó el paso de la ‘era de la contradicción’ a la ‘era de la marginalización’. Actualmente, un gran número de migrantes indocumentados permanecen al margen de la ley, precisamente en un periodo en el que las penas se han incrementado y la persecución ha alcanzado niveles récord. De manera cada vez más notoria, los migrantes indocumentados, por la represión interna y fronteriza, quedan obligados a romper los lazos que los vinculaban con sus lugares de destino, pero al mismo tiempo se sienten cada vez más extraños en una tierra donde la aplicación de políticas antiinmigrantes es cosa de todos los días, lo que los sitúa en una posición de marginalización y gran vulnerabilidad.

    Systematic searches using the complete genome sequence of rice (Oryza sativa) identified OsSUS7, a new member of the rice sucrose synthase (OsSUS) gene family, which shows only nine single nucleotide substitutions in the OsSUS5 coding sequence. Comparative genomic analysis revealed that the synteny between OsSUS5 and OsSUS7 is conserved, and that significant numbers of transposable elements are scattered at both loci. In particular, a 17.6-kb genomic region containing transposable elements was identified in the 5? upstream sequence of the OsSUS7 gene. GFP fusion experiments indicated that Os- SUS5 and OsSUS7 are largely associated with the plasma membrane and partly with the cytosol in maize mesophyll protoplasts. RT-PCR analysis and transient expression assays revealed that OsSUS5 and OsSUS7 exhibit similar expression patterns in rice tissues, with the highest expression evident in roots. These results suggest that two redundant genes, OsSUS5 and OsSUS7, evolved via duplication of a chromosome region and through the transposition of transposable elements. PMID:21533550

  10. Results of fracture mechanics tests on PNC SUS 304 plate

    1985-08-01

    PNC provided SUS 304 plate to be irradiated in FFTF at about 400/sup 0/C to a target fluence of 5 x 10/sup 21/ n/cm/sup 2/ (E > 0.1 MeV). The actual irradiation included two basically different exposure levels to assure that information would be available for the exposure of interest. After irradiation, tensile properties, fatigue-crack growth rates and J-integral fracture toughness response were determined. These same properties were also measured for the unirradiated material so radiation damage effects could be characterized. This report presents the results of this program. It is expected that these results would be applicable for detailed fracture analysis of reactor components. Recent advances in elastic-plastic fracture mechanics enable reasonably accurate predictions of failure conditions for flawed stainless steel components. Extensive research has focused on the development of J-integral-based engineering approach for assessing the load carrying capacity of low-strength, high-toughness structural materials. Furthermore, Kanninen, et al., have demonstrated that J-integral concepts can accurately predict the fracture response for full-scale cracked structures manufactured from Type 304 stainless steel.

    A 2-year-old, spayed female Vietnamese potbellied pig (Sus scrofa) was evaluated due to polyuria, polydipsia, lethargy, and hyporexia. The pig was obese, and a large abdominal mass was palpated. Additional findings included hypercalcemia, hyperglycemia, glucosuria, and an inflammatory leukogram. At surgery, the abdominal mass was biopsied and found to be bilaterally symmetric adipose tissue with mineralization and granulomatous steatitis. An additional surgery was performed to collect additional diagnostic samples, but the pig died while recovering from anesthesia. A cosmetic necropsy was performed, and lipid emboli were identified microscopically in various tissues. The presence of lipid emboli in the lung and kidney was supported by antifibrinogen immunohistochemistry. Obesity is a common finding in potbellied pigs; however, mineralization and saponification of fat are uncommon, particularly the bilateral symmetrical distribution found in the abdomen of the present case. This may present as a single intra-abdominal mass complicating diagnostic interpretation. Whether mineralization and saponification of fat facilitate the development of fat embolism is undetermined. Lipid emboli should be considered in obese pigs undergoing medical or surgical procedures. Factors that may predispose to the development of fat embolism, such as excessive handling or bruising of fat stores, should be avoided. PMID:22529140

    This article analyzes the level of progressivity in taxes financing the Brazilian Unified National Health System (SUS). Distribution of the tax burden financing the SUS was calculated using micro-data from the Household Budgets Survey, 2002-2003. The Kakwani index, which shows a tax system's level of progressivity, was calculated. The Kakwani index of public financing was -0.008, and SUS financing was nearly proportional to income. From a social justice perspective this is highly undesirable in a society like Brazil, with a Gini index of 0.57. The system should be clearly progressive in order to counterbalance the country's extreme income concentration. PMID:16832531

    Sucrose synthase (SUS; EC 2.4.1.13) plays important roles in sugar metabolism and abiotic stress response. But the genes encoding SUS in cucumber (Cucumis sativus?L.) have not been well studied. Here, we isolated four cucumber sucrose synthase genes (CsSUS). Among them, CsSUS3, which highly expressed in the roots, was chosen for further study. Immunolocalization and subcellular localization analysis indicated that CsSUS3 localized in the cytosol and the plasma membrane, and mainly existed in the companion cells of phloem in the roots. When suffering hypoxia stress from flooding, CsSUS3 expression and SUS activity in roots increased, especially in the lateral roots; moreover, the soluble SUS activity increased clearly, but the membrane fraction hardly changed. Compared with the wild-type cucumbers, the transgenic lines with antisense expression of CsSUS3 were more sensitive to flooding. After 6 d of flooding, the SUS activity, soluble sugar and uridine 5'-diphosphate glucose (UDPG) content and the ratio of ATP/ADP in the roots of transgenic plants were significantly lower than that in wild-type plants. Moreover, the transgenic lines grew more slowly with more yellow necrosis in the leaves. These findings suggested CsSUS3 participated in resisting hypoxic stress. Furthermore, the mechanism of CsSUS3 in resisting hypoxic stress was also discussed. PMID:24028217

    The distribution of residual stress of SUS304 samples that were undergone TIG welding process with four different electric currents has been measured. The welding has been done in the middle part of the samples that was previously grooved by milling machine. Before they were welded the samples were annealed at 650 degree Celsius for one hour. The annealing process was done to eliminate residual stress generated by grooving process so that the residual stress within the samples was merely produced from welding process. The calculation of distribution of residual stress was carried out by measuring the strains within crystal planes of Fe(220) SUS304. Strain, Young modulus, and Poisson ratio of Fe(220) SUS304 were measured using DN1-M neutron diffractometer. Young modulus and Poisson ratio of Fe(220) SUS304 sample were measured in-situ. The result of calculations showed that distribution of residual stress of SUS304 in the vicinity of welded area is influenced both by treatments given at the samples-making process and by the electric current used during welding process.

    Sucrose synthase (SUS) converts sucrose and uridine di-phosphate (UDP) into UDP-glucose and fructose. UDP-glucose is used by the cellulose synthase to produce cellulose for cell wall biosynthesis. For lignocellulosic feedstocks such as switchgrass, the manipulation of cell walls to decrease lignin content is needed to reduce recalcitrance of conversion of biomass into biofuels. Of perhaps equal importance for bioenergy feedstocks is increasing biomass. Four SUS genes were identified in switchgrass. Each gene contained 14 or 15 introns. PvSUS1 was expressed ubiquitously in the tissues tested. PvSUS2 and PvSUS6 were highly expressed in internodes and roots, respectively. PvSUS4 was expressed in low levels in the tissues tested. Transgenic switchgrass plants overexpressing PvSUS1 had increases in plant height by up to 37%, biomass by up to 13.6%, and tiller number by up to 79% compared to control plants. The lignin content was increased in all lines, while the sugar release efficiency was decreased in PvSUS1-overexpressing transgenic switchgrass plants. For switchgrass and other bioenergy feedstocks, the overexpression of SUS1 genes might be a feasible strategy to increase both plant biomass and cellulose content, and to stack with other genes to increase biofuel production per land area cultivated.

    2006-10-01

    Two-dimensional temperature rising in an austenitic stainless steel SUS304 trench object with plasma-based ion implantation (PBII) was numerically simulated, where the thermal input on the surface of the trench structure was derived from the calculation of plasma sheath evolution. The difference in temperature distribution was a few Kelvin although the convex corner of the trench had a larger thermal flux than the concave corner. Using the calculated temporal evolution of object temperature, we numerically studied the diffusion of implanted nitrogen ions in the SUS304 trench surface heated by PBII. In addition, the formation of the expanded austenitic phase ?'N-Fe, which can enhance the hardness of the material, is discussed on the basis of the calculated depth profile of the implanted nitrogen.

    Newly developed Pd-Ag-Mn system braze alloys were considered for use in brazing stainless steel SUS316L or Ni-based alloy Inconel 600 for engine applications. Palladium braze alloys were selected because of their oxidation resistance, ductility, relatively high melting points, and lower cost than gold-based braze alloys. The reactions and microstructures were studied in experimental brazed joints between these base metals and the braze alloys. Tensile tests of the joints were carried out at room temperature, 473K, 673K, 873K, and 1,073K. The maximum tensile strengths of the joints brazed with 30Pd-60Ag-10Co at room temperature were 445MPa in the SUS316L joints and 456MPa in the Inconel 600 brazed joints. The SUS316L joints brazed with the braze alloys had tensile strengths of 320MPa to 200MPa from 473K to 1,73K. The Inconel 600 joints brazed with the 30Pd-50Ag-10Mn-10Co alloy had tensile strengths of 289MPa to 162MPa from 473K to 1,073K.

    Given the relevance of the pig proteome in different studies, including human complex maladies, a statistical validation of the annotation is required for a better understanding of the role of specific genes and proteins in the complex networks underlying biological processes in the animal. Presently, approximately 80% of the pig proteome is still poorly annotated, and the existence of protein sequences is routinely inferred automatically by sequence alignment towards preexisting sequences. In this article, we introduce SUS-BAR, a database that derives information mainly from UniProt Knowledgebase and that includes 26 206 pig protein sequences. In SUS-BAR, 16 675 of the pig protein sequences are endowed with statistically validated functional and structural annotation. Our statistical validation is determined by adopting a cluster-centric annotation procedure that allows transfer of different types of annotation, including structure and function. Each sequence in the database can be associated with a set of statistically validated Gene Ontologies (GOs) of the three main sub-ontologies (Molecular Function, Biological Process and Cellular Component), with Pfam functional domains, and when possible, with a cluster Hidden Markov Model that allows modelling the 3D structure of the protein. A database search allows some statistics demonstrating the enrichment in both GO and Pfam annotations of the pig proteins as compared with UniProt Knowledgebase annotation. Searching in SUS-BAR allows retrieval of the pig protein annotation for further analysis. The search is also possible on the basis of specific GO terms and this allows retrieval of all the pig sequences participating into a given biological process, after annotation with our system. Alternatively, the search is possible on the basis of structural information, allowing retrieval of all the pig sequences with the same structural characteristics. PMID:24065691

    An outbreak of salmonellosis was recorded in captive pygmy hogs (Sus salvanius), a critically endangered species of mammal. Of 42 captive animals maintained for conservation breeding by the Pygmy Hog Conservation Programme, Guwahati, Assam, India, 7 (16.67%) died within 3 days. The organism associated with this outbreak was identified as Salmonella enteritidis. The organisms were highly susceptible to chloramphenicol, gentamicin, norfloxacin and cefotaxim but were resistant to ampicillin, oxytetracycline, mezlocillin and sulfamerazin. The strain belonged to phage type 13a/7 and harboured two plasmids (38 and 44 megadaltons). The organisms were enterotoxigenic in CHO cell assay and were found to carry stn, sef and pef genes.

    The section of Gârbova de Sus contains diverse fossil groups and rich bryozoan assemblages, with 77 species altogether. Several taxa have been recognized as very important in the assemblage and two new taxa are described in detail: Poricella garbovensis sp. nov. and Therenia transylvanica sp. nov. Foraminifera and calcareous nannofossil assemblages were used for biostratigraphic and paleoenvironmental interpretations. On the basis of sedimentological features and micropaleontological data, the sequence of paleoenvironments can be subdivided into two intervals indicating slightly different climatic conditions.

    Abstract Toxoplasma gondii is an obligate intracellular protozoan parasite and a commonly encountered pathogen in humans and animals. The wild boar (Sus scrofa coreanus) is considered a good indicator when monitoring environmental contamination by T. gondii. We surveyed the prevalence of antibodies against T. gondii in wild boars from South Korea. Blood samples were collected from 426 wild boars captured in eight provinces of South Korea during the hunting seasons in 2008-12. Antibodies against T. gondii were detected using an indirect enzyme-linked immunosorbent assay in samples from 152 of boars, indicating an overall antibody prevalence of 36% (95% confidence interval=31-40%).

    From 2011 to 2012, to identify Cryptosporidium spp. occurrence in Eurasian wild boars (Sus scrofa) 29 randomly selected localities (both forest areas and enclosures) across the Central European countries of Austria, the Czech Republic, Poland, and the Slovak Republic were investigated. Cryptosporidium oocysts were microscopicaly detected in 11 out of 460 faecal samples examined using aniline-carbol-methyl violet staining. Sixty-one Cryptosporidium infections, including the 11 infections that were detected by microscopy, were detected using genus- or species-specific nested PCR amplification of SSU rDNA. This represents a 5.5 fold greater sensitivity for PCR relative to microscopy. Combining genus-and species-specific PCR tools significantly changes the perspective on the occurrence of Cryptosporidium spp. in wild boars. While RFLP and direct sequencing of genus specific PCR-amplified products revealed 56 C. suis (20) and C. scrofarum (36) monoinfections and only 5 mixed infections of these species, species-specific molecular tools showed 44 monoinfections and 17 mixed infections with these species. PCR analysis of the gp60 gene did not reveal any other Cryptosporidium infections. Similar to domestic pigs, C. scrofarum was detected as a dominant species infecting adult Eurasian wild boars (Sus scrofa). Cryptosporidium infected wild boars did not show signs of clinical disease. This report is perhaps the most comprehensive survey of cryptosporidial infection in wild boars. PMID:23916060

    Lysozyme has played an important role in animal feed additive industry, food additive industry and biological engineering. For improving expression efficiency of recombinant lysozyme from Sus scrofa, two genes respectively designed by the most used codon optimization strategies, "one amino acid one codon" and "codon randomization", were synthesized and expressed in Pichia pastoris X—33. At shaking flask level, Sus scrofa lysozyme (SSL) under two conditions had a highest activity of 153.33±10.41 and 538.33±15.18 U/mL after a 5 days induction of 1% methanol, with secreted protein concentration 80.03±1.94 and 239.60±4.16 mg/L, respectively. Compared with the original SSL gene, the expression of optimized SSL gene by the second strategy showed a 2.6 fold higher level, while the first method had no obvious improvement in production. In total secreted protein, the proportions of recombinant SSL encoded by the original gene, first method optimized gene and the second—strategy optimized one were 75.06±0.25%, 74.56±0.14% and 79.00±0.14%, respectively, with the same molecular weight about 18 kDa, optimum acidity pH 6.0 and optimum temperature 35degC.

    It is important to understand the proliferative activity of the different structures of the male reproductive apparatus in livestock species, such as Sus domesticus, to ensure reproductive efficiency. The main aims of this study were (a) to evaluate the proliferative activity of the spermatogonia in the different stages of the seminiferous cycle and (b) to study the cell proliferation in the epididymal epithelium in each region, identifying the different cells involved. For this, the testes and epididymis of three healthy, sexually mature Sus domesticus boars were used. The organs were processed for light microscopy, and immunohistochemical techniques were used to detect proliferating cell nuclear antigen. The cells immunostaining positively and negatively for proliferating cell nuclear antigen were counted and several parameters and indexes were calculated to evaluate the proliferation in both epithelia, taking into account the stage of the seminiferous epithelium cycle, and, in the case of the epididymal epithelium, the different regions and cells are the same. Finally, a contrast analysis of equality between pairs of means was carried out followed by a least significant differences test, in which differences were considered significant at P < 0.05. In the seminiferous epithelium, the greatest total number of spermatogonia and proliferating spermatogonia was observed in the postmeiotic stages (mainly VII and VIII). The proliferation index of the spermatogonia increased from the meiotic to postmeiotic stages. As regards the epididymal epithelium, the total proliferation index was higher in the caput. In each region, the clear and principal cells showed the highest proliferation index with respect to the total number of cells counted, whereas the proliferation index of each cell with respect to the same type was higher in the clear cells, followed by the narrow and principal cells. In conclusion, the proliferative activity of spermatogonia in the seminiferous epithelium of Sus domesticus is stage-dependent, and mainly occurs in the postmeiotic stages. In the epididymal epithelium, proliferative activity takes place in several cell types and is dependent on the anatomical region of the epididymis. We think that these results may be of importance for understanding the pathologic or reproductive processes in which cell proliferation is involved in the male reproductive system. PMID:24418529

    The microstructures of heavily neutron-irradiated specimens of compositionally-modified SUS316 stainless steel of were carefully studied and characterized by transmission electron microscopy (TEM) to establish the onset mechanism of radiation-induced swelling and to characterize the effects of neutron irradiation on the microstructures. Materials with remarkably high swelling were included. It is demonstrated that the microstructural evolution, including the radiation-induced swelling, depends strongly on the irradiation conditions. The relationship between the onset of swelling and microstructural evolution is complex while the effect of irradiation temperature are relatively large. The mechanisms controlling the onset of swelling at a specific temperature or temperature range are discussed based on the microstructures.

    Free-ranging wildlife, such as feral swine (Sus scrofa), harbor a variety of diseases that are transmissible to livestock and could negatively impact agricultural production. Information is needed regarding the exposure and infection rates of Mycobacterium bovis and many other diseases and parasites in feral swine occurring in the Texas border region. Our main objective was to determine exposure rates and possible infection rates of M. bovis in feral swine by opportunistically sampling animals from the Texas border region. From June to September 2010, we obtained samples from 396 feral swine and tested 98 samples for M. bovis by histopathology and mycobacteriologic culture. We found no evidence of M. bovis infection. We believe that it is important to periodically and strategically sample feral swine for M. bovis in high-risk areas of the United States because they are capable of becoming reservoirs of the disease.

    We pursued several strategies for expressing either full-length Sus scrofa diacylglycerol kinase (DGK) alpha or the catalytic domain (alphacat) in Escherichia coli. Alphacat could be extracted, refolded, and purified from inclusion bodies, but when subjected to analytical gel filtration chromatography, it elutes in the void volume, in what we conclude are microscopic aggregates unsuitable for x-ray crystallography. Adding glutathione S-transferase, thioredoxin, or maltose binding protein as N-terminal fusion tags did not improve alphacat's solubility. Coexpressing with bacterial chaperones increased the yield of alphacat in the supernatant after high-speed centrifugation, but the protein still elutes in the void upon analytical gel filtration chromatography. We believe our work will be of interest to those interested in the structure of eukaryotic DGKs, so that they know which expression strategies have already been tried, as well as to those interested in protein folding and those interested in chaperone/target-protein interactions.

    A hypothetical protein is predicted to be expressed from an open reading frame without known experimental evidence of translation. They constitute a substantial fraction of proteomes. Domain extraction from these hypothetical sequences helps to search for protein coding genes for protein structural and functional annotation. We describe the analysis of prediction data in a sequence dataset of hypothetical protein orthologs of Pongo abelii (orangutan) and Sus scrofa (pig). It should be noted that these orangutan-pig orthologs are also non-homologous to human proteins. These predicted data find application in the genome wide annotation of proteins in poorly understood genomes.

    Between January and December 2013, the dental and periodontal health of 99 Swedish wild boars (Sus scrofa) was investigated. Sampling occurred in conjunction with routine hunting at six large estates in the southern and middle parts of Sweden. All six of the estates use supplemental feeding. The weight of the animals, their sex and their dates of death were noted. Age was estimated using tooth eruption and tooth replacement patterns. The oral cavity was inspected and abnormalities were recorded on a dental chart modified for wild boars. The findings included supernumerary teeth, absence of teeth, mild class II malocclusion, severe tooth wear, periodontitis, calculus, caries, tooth fractures and the presence of enamel defects. Swedish wild boars suffer from different dental lesions and the impact of supplemental feeding on dental and periodontal health is still to be investigated. PMID:25979683

    Streptococcus suis is a recognized pathogen that may cause important diseases in pigs and humans. This microorganism has been repeatedly isolated from wild boar ( Sus scrofa ). However, its health implications for this wild species are still unknown. This article reports a detailed description of a fatal case of septicemia by S. suis affecting a young wild boar. The affected animal, about 15 days old, was found near death and exhibiting neurologic signs at a wild boar estate in southwestern Spain. Postmortem examination showed generalized congestion, brain hemorrhages and lobular pneumonia. Histopathological evaluation demonstrated the presence of meningitis and encephalitis with marked congestion and suppurative bronchopneumonia. Streptococcus suis serotype 2 isolates exhibiting important virulence factors (extracellular factor, muramidase-released protein, and suylisin) were isolated from the affected animal. This study confirms the presence of potentially virulent and zoonotic strains of S. suis in wild boar from Spain. PMID:26056897

    Feral swine (Sus scrofa) are widely distributed in the United States. In 2011 and 2012, serum samples and tonsils were recovered from 162 and 37 feral swine, respectively, in the US to evaluate exposure to important swine endemic pathogens. Antibodies against porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) were found in 2.5% and 25.3% of tested sera, respectively. Positive serological reactions against Mycoplasma hyopneumoniae and Actinobacillus pleuropneumoniae have been detected in 19.7% and 69.7% of animals. More than 15% of animals presented antibodies against these 2 pathogens simultaneously. Most animals were also seropositive for Lawsonia intracellularis. Feral swine can also be involved in transmission of zoonotic agents. Almost 50% of animals possessed antibodies against Salmonella. In addition, 94.4% of animals were carriers of Streptococcus suis in their tonsils. In conclusion, feral swine may be considered as a potential reservoir for different endemic diseases in domestic pigs, as well as for important zoonotic agents. PMID:25673913

    Light-absorbing aerosols, such as black carbon (BC), are major contributors to the atmospheric heating and the reduction of solar radiation reaching at the earth's surface. In this study, we investigate light-absorption and scattering properties of aerosols (i.e., BC mass concentration, aerosol solar-absorption/scattering efficiency) in the Kathmandu valley during Sustainable atmosphere for the Kathmandu valley (SusKat)-ABC campaign, from December 2012 to February 2013. Kathmandu City is among the most polluted cities in the world. However, there are only few past studies that provide basic understanding of air pollution in the Kathmandu Valley, which is not sufficient for designing effective mitigation measures (e.g., technological, financial, regulatory, legal and political measures, planning strategies). A distinct diurnal variation of BC mass concentration with two high peaks observed during wintertime dry monsoon period. BC mass concentration was found to be maximum around 09:00 and 20:00 local standard time (LST). Increased cars and cooking activities including substantial burning of wood and other biomass in the morning and in the evening contributed to high BC concentration. Low BC concentrations during the daytime can be explain by reduced vehicular movement and cooking activities. Also, the developmements of the boundary layer height and mountain-valley winds in the Kathmandu Valley paly a crucial role in the temproal variation of BC mass concentrations. Detailed radiative effects of light-absorbing aerosols will be presented.

    Antimicrobial resistance of bacteria is a worldwide problem affecting wild life by living with resistant bacteria in the environment. This study presents a discussion of outside factors environment on microflora of feral pigs (Sus scrofa) from Brazilian Pantanal. Animals had samples collected from six different body sites coming from two separated geographic areas, Nhecolandia and Rio Negro regions. With routine biochemical tests and commercial kits 516 bacteria were identified, with 240 Gram-positive, predominantly staphylococci (36) and enterococci (186) strains. Among Gram-negative (GN) bacteria the predominant specimens of Enterobacteriaceae (247) mainly represented by Serratia spp. (105), Escherichia coli (50), and Enterobacter spp. (40) and specimens not identified (7). Antimicrobial susceptibility was tested against 17 drugs by agar diffusion method. Staphylococci were negative to production of enterotoxins and TSST-1, with all strains sensitive towards four drugs and highest resistance toward ampicillin (17%). Enterococci presented the highest sensitivity against vancomycin (98%), ampicillin (94%) and tetracycline (90%), and highest resistance pattern toward oxacillin (99%), clindamycin (83%), and cotrimoxazole (54%). In GN the highest resistance was observed with Serratia marcescens against CFL (98%), AMC (66%) and AMP (60%) and all drugs was most effective against E. coli SUT, TET (100%), AMP, TOB (98%), GEN, CLO (95%), CFO, CIP (93%). The results show a new profile of oxacillin-resistant enterococci from Brazilian feral pigs and suggest a limited residue and spreading of antimicrobials in the environment, possibly because of low anthropogenic impact reflected by the drug susceptibility profile of bacteria isolated.

    Technological incorporation is a central topic among the concerns regarding health care systems. This paper discusses the role of technology dynamics in health systems' cost increases, suggesting two different approaches - a 'pragmatic-economic' approach and a 'rational-defensive' approach - as guidelines to explain the reasons for this centrality. The paper shows how judicialization results from this situation and discusses two doctrinal views - 'reserve for contingencies' and 'rational use' - as the views that usually guide the debates in the courts and among health policy makers. The paper suggests that the attitude currently prevalent in the Brazilian judiciary system can prejudice the principle of equity by improperly evaluating the principle of integrality. We present a brief genealogy of HTA and a timeline of HTA in Brazil. We also discuss the relevance and the impact of Law 12401/2011, which regulates the principle of integrality in the Unified Health System (SUS) and propose three challenges to the development of HTA actions aiming at technology incorporation in Brazil. Finally, we discuss the entry and the role of private health insurance companies, emphasizing changes in the scenario and in their position. PMID:25388198

    Next generation sequencing of mitochondrial DNA (mtDNA) facilitates studies into the metabolic characteristics of production animals and their relation to production traits. Sequence analysis of mtDNA from pure-bred swine with highly disparate production characteristics (Mangalica Blonde, Mangalica Swallow-bellied, Meishan, Turopolje, and Yorkshire) was initiated to evaluate the influence of mtDNA polymorphisms on mitochondrial function. Herein, we report the complete mtDNA sequences of five Sus scrofa breeds and evaluate their position within the phylogeny of domestic swine. Phenotypic traits of Yorkshire, Mangalica Blonde, and Swallow-belly swine are presented to demonstrate their metabolic characteristics. Our data support the division of European and Asian breeds noted previously and confirm European ancestry of Mangalica and Turopolje breeds. Furthermore, mtDNA differences between breeds suggest function-altering changes in proteins involved in oxidative phosphorylation such as ATP synthase 6 (MT-ATP6), cytochrome oxidase I (MT-CO1), cytochrome oxidase III (MT-CO3), and cytochrome b (MT-CYB), supporting the hypothesis that mtDNA polymorphisms contribute to differences in metabolic traits between swine breeds. Our sequence data form the basis for future research into the roles of mtDNA in determining production traits in domestic animals. Additionally, such studies should provide insight into how mtDNA haplotype influences the extreme adiposity observed in Mangalica breeds. PMID:25153451

    Shot peening is a mechanical surface modification technology, which can extend the fatigue life of materials by introducing work hardening, compressive stress, and/or some additional microstructural change in surface layer resulting in a restraint of crack initiation and propagation on the surface. In this study, SUS304, which has high formability and corrosion resistance, was shot peened and fatigued for the determination of their effect on the evolution of microstructures. The fatigue of the specimens were carried out at three different cycles, followed by second shot peening and finish fatigue of 106 cycles. The microstructures of the specimens were investigated using OM, EBSD, SED and EDS. The resulting mechanical property such as microhardness and residual stress was also investigated. Deformed layer of ~100?m and mechanical twins were observed after fatigue and shot peening test. The top surface layer of shot peened specimen showed the highest twin density and microhardness. The increase of the fatigue before shot peening caused increase and deepening of the compressive residual stress. However, the finish fatigue of 106 cycles decreased overall compressive residual stress.

    The changing of materials surface properties method always was taken into improving the fatigue strength. In this paper, an ultrasonic nanocrystal surface modification(UNSM) technique was used on the SUS 304 stainless steel to form a nanostructured surface layer with different static load(70N, 90N, 110N, 130N) and the vibration strike number was about 20,000times/mm2. The untreated and different condition specimens fatigue strength was all tested by a dual-spindle rotating bending fatigue test machine. SPring-8(a large synchrotron radiation facility) was used to test the surface nanocrystallization components. The X-ray diffraction (XRD), the scanning electron microscopy (SEM), optical microscope and a micro-Vickers hardness tester (MVK-E3, Akashi) were separately used to get the surface residual stresses, fracture surface after fatigue testing, metallographic structure and the microhardness of the nanostructured surface layer. The result showed that martensite transformation took place on the surface of specimens, the surface residual stresses had only a small increase and some cracks occurred between the martensite layer and the austenite layer, but the fatigue strength of 90N improved 81%.

    Leptospirosis is a zoonosis of worldwide distribution, caused by infection with pathogenic spirochaetes of the genus Leptospira. The wild boar (Sus scrofa), an important hunting species in Europe, seems to play a significant role in the epidemiological cycle of leptospirosis. A total of 101 serum samples from wild boar hunted in Northern Portugal were analysed for leptospiral antibodies detection by microscopic agglutination test. Sera were collected during hunting seasons (2011-2013) and tested with 17 different pathogenic serovars of Leptospira. Antibodies against nine serovars were detected in 66 (65·4%) of these sera. Serovars Tarassovi and Altodouro exhibited the highest seroreactivity rates (23·8% and 16·8%, respectively), followed by Autumnalis (7·9%) and Bratislava (6·9%). Age and district of origin were found to be risk factors for the presence of leptospiral antibodies in contrast to gender. From a One Health perspective, this study revealed that wild boar should be considered as a potential source of leptospirosis dissemination for humans and animal species (domestic and wild) in shared environments, particularly in the Trás-os-Montes region.

    The aim of this study was to further investigate the role of wild boar (Sus scrofa) as a reservoir for hepatitis E virus (HEV). Sixty-four blood and faecal samples collected from wild boar hunted in Central Italy in 2011-2012 were examined by indirect enzyme-linked immunosorbent assay and RT-PCR analysis. Positive RT-PCR samples were further examined by nucleotide sequence determination and subsequent phylogenetic analysis. Thirty-six sera (56.2%) were positive for HEV-specific antibodies, and six (9.4%) faecal samples scored RT-PCR-positive results. Four animals were positive by both enzyme-linked immunosorbent assay and RT-PCR. Phylogenetic analysis showed that the detected wild boar-derived HEV sequences clustered within genotype 3, with similarity to sequences of human origin collected in a nearby area in 2012. Our data confirm that HEV is endemic in the wild boar population in the research area and that these wild animals could play an important role in the epidemiology of HEV infection. PMID:26199731

    Background Wild boar, Sus scrofa, is an extant wild ancestor of the domestic pig as an agro-economically important mammal. Wild boar has a worldwide distribution with its geographic origin in Southeast Asia, but genetic diversity and genetic structure of wild boar in East Asia are poorly understood. To characterize the pattern and amount of genetic variation and population structure of wild boar in East Asia, we genotyped and analyzed microsatellite loci for a total of 238 wild boar specimens from ten locations across six countries in East and Southeast Asia. Results Our data indicated that wild boar populations in East Asia are genetically diverse and structured, showing a significant correlation of genetic distance with geographic distance and implying a low level of gene flow at a regional scale. Bayesian-based clustering analysis was indicative of seven inferred genetic clusters in which wild boars in East Asia are geographically structured. The level of genetic diversity was relatively high in wild boars from Southeast Asia, compared with those from Northeast Asia. This gradient pattern of genetic diversity is consistent with an assumed ancestral population of wild boar in Southeast Asia. Genetic evidences from a relationship tree and structure analysis suggest that wild boar in Jeju Island, South Korea have a distinct genetic background from those in mainland Korea. Conclusions Our results reveal a diverse pattern of genetic diversity and the existence of genetic differentiation among wild boar populations inhabiting East Asia. This study highlights the potential contribution of genetic variation of wild boar to the high genetic diversity of local domestic pigs during domestication in East Asia. PMID:25034725

    Anelloviruses are a group of single-stranded circular DNA viruses infecting several vertebrate species. Four species have been found to infect swine, namely Torque teno sus virus (TTSuV) 1a and 1b (TTSuV1a, TTSuV1b; genus Iotatorquevirus), TTSuVk2a and TTSuVk2b (genus Kappatorquevirus). TTSuV infection in pigs is distributed worldwide, and is characterized by a persistent viremia. However, the real impact, if any, on the pig health is still under debate. In the present study, the impact of pig immunization on TTSuVk2a loads was evaluated. For this, three-week old conventional pigs were primed with DNA vaccines encoding the ORF2 gene and the ORF1-A, ORF1-B, and ORF1-C splicing variants and boosted with purified ORF1-A and ORF2 Escherichia coli proteins, while another group served as unvaccinated control animals, and the viral load dynamics during natural infection was observed. Immunization led to delayed onset of TTSuVk2a infection and at the end of the study when the animals were 15 weeks of age, a number of animals in the immunized group had cleared the TTSuVk2a viremia, which was not the case in the control group. This study demonstrated for the first time that TTSuV viremia can be controlled by a combined DNA and protein immunization, especially apparent two weeks after the first DNA immunization before seroconversion was observed. Further studies are needed to understand the mechanisms behind this and its impact for pig producers. PMID:26051513

    The morphology of the hair cells of the inner ear end organs from the domestic pig (Sus scrofa) have been studied using a combination of Scanning and Transmission Electron Microscopy (SEM and TEM), revealing hair cells from the cochlea and vestibule using a novel surgical and technical approach. This is the first time that the inner ear hair cells from S. scrofa have been studied, thus providing useful anatomical information on the morphology of the hair cells from the cochlea, saccule and utricle from a large mammal. Anatomical information in relation to the morphology of the inner ear is of considerable importance, both in the pathological diagnosis of trauma and in the development of cochlea implants and other biotechnological systems associated with the enhancement of hearing. Standard fixation protocols using cardiac perfusion was not employed in this study as this method cannot always be applied, such as the pathological examination of the human ear, or the study of animals protected by endangered species legislation. With the exception of a very few countries, cetaceans cannot be killed for research purposes, yet physiological information on the inner ear from these species is urgently required for ecological assessment reasons. Supporting the use of S. scrofa as a model for cetacean hearing research is that this animal is a member of the order Artiodactyla, which includes both the hippopotamus and cetaceans. Being of a similar size, the pig is an ideal subject for developing protocols and surgical techniques required to investigate both the human and small cetacean auditory systems. PMID:18045329

    The force flow cooled superconducting cable-in-conduit conductor (CICC) is used in both of EAST toroidal field (TF) and poloidal field (PF) coils. The conductor consists of multi-stage NbTi superconducting cable and 1.5 mm thick square jacket. The cable is pulled through in a thin wall circular jacket and then compacted to square cross-section conductor. The jacket material is SUS316LN austenitic stainless steel seamless tubes (about 10 m each), which is assembled by butt-welding up to 600 m. The results of the welding procedure investigation and quality assurance procedures carrying out are described in this paper.

    Alumina ceramic (?-Al2O3) was brazed to stainless steel (SUS304) using an Ag-Cu-Ti + W composite filler and a traditional active brazing filler alloy (CuSil-ABA). Then, the effects of the presence of W particles and of the brazing parameters on the microstructures and mechanical properties of the brazed joints were investigated. The maximum tensile strength of the joints obtained using Ag-Cu-Ti + W composite filler was 13.2 MPa, which is similar to that obtained using CuSil-ABA filler (13.5 MPa). When the joint was brazed at 930 °C for 30 min, the tensile strengths decreased for both kinds of fillers, although the strength was slightly higher for the Ag-Cu-Ti + W composite filler than for the Ag-Cu-Ti filler. The interfacial microstructure results show that the Ti reacts with W to form a Ti-W-O compound in the brazing alloy. When there are more W particles in the brazing alloy, the thickness of the Ti X O Y reaction layer near the alumina ceramic decreases. Moreover, W particles added to the brazing alloy can reduce the coefficient of thermal expansion of the brazing alloy, which results in lower residual stress between the Al2O3 and SUS304 in the brazing joints and thus yields higher tensile strengths as compared to those obtained using the CuSil-ABA brazing alloy.

    To know the status of sparganum (plerocercoid of Spirometra erinacei) infection in the Korean wild life, several species of wild animals were captured in Gangwon-do and examined for their status of infection with spargana. From February to December 2011, a total of 62 wild boars, 5 badgers, 1 weasel, 1 Siberian chipmunk, and 53 wild rodents were captured, and their whole muscles were examined with naked eyes for the presence of spargana worms. From the weasel and 1 wild boar, a total of 5 spargana specimens were extracted. The weasel was for the first time recorded as an intermediate or paratenic/transport host of S. erinacei in Korea, and both the weasel (Mustela sibirica manchurica) and wild boar (Sus scrofa) were added to the list of wild animals carrying spargana.

    Serum samples were collected from wild boars (Sus scrofa) harvested during the 2005-2006 hunting season in Campania, southern Italy. Samples were tested for antibodies to Leptospira interrogan, Brucella spp., Salmonella spp., Aujeszky disease virus (ADV), porcine reproductive and respiratory stress syndrome virus (PRRSV), porcine parvovirus (PPV), classical swine fever virus (CSFV), and swine vesicular disease virus (SVDV). Of the 342 serum samples tested, 15 (4.4%) were seropositive to Brucella spp., nine (2.6%) were seropositive to L. interrogans, 66 (19.3%) were seropositive for Salmonella spp., 105 (30.7%) were seropositive for ADV, 27 (7.9%) were seropositive for PPV, and 129 (37.7%) were seropositive for PRRSV. All sera tested seronegative for SVDV and CSFV antibodies. These results, recorded for the first time in Campania, support the hypothesis that wild boar are reservoirs of certain infectious agents, but some infections in wild boars originate from their domestic counterparts.

    This study aimed at correlating selected carcass borne volatile organic compounds (VOCs) with the postmortem interval (PMI). Selected volatiles should 1st be reliably emitted during vertebrate decay, 2nd be emitted at high concentrations, and 3rd show a reproducible quantitative dynamic during the decaying process. Four pigs (Sus scrofa domesticus L.) were placed in a deciduous forest in different seasons and volatiles emitted during the decaying process were sampled. Seventeen compounds were identified and quantified by GC-MS. Electrophysiological experiments on the antenna of female Calliphora vicina and additional data of Dermestes maculans were used as an evolutionary tuned information filter to evaluate the 1st criterion. The relative quantitative emission of hexanal, nonanal, dimethyl disulfide, dimethyl trisulfide, 1-butanol, and phenol were correlated with the PMI, and the observed stages of decay and the limitations of this model were discussed.

    Edge-effects greatly extend the area of tropical forests degraded through human activities. At Pasoh, Peninsular Malaysia, it has been suggested that soil disturbance by highly abundant wild pigs (Sus scrofa), which feed in adjacent Oil Palm plantations, may have mediated the invasion of Clidemia hirta (Melastomataceae) into the diverse tropical lowland rain forest. To investigate this hypothesis, we established three 1 km transects from the forest/Oil Palm plantation boundary into the forest interior. We recorded the distribution of soil disturbance by wild pigs, C. hirta abundance, and environmental variables. These data were analyzed using a hierarchical Bayesian model that incorporated spatial auto-correlation in the environmental variables. As predicted, soil disturbance by wild pigs declined with distance from forest edge and C. hirta abundance was correlated with the level of soil disturbance. Importantly there was no effect of distance on C. hirta abundance, after controlling for the effect of soil disturbance. Clidemia hirta abundance was also correlated with the presence of canopy openings, but there was no significant association between the occurrence of canopy openings and distance from the edge. Increased levels of soil disturbance and C. hirta abundance were still detectable approximately 1 km from the edge, demonstrating the potential for exceptionally large-scale animal mediated edge effects.

    This paper redeems the significance of the health reform movement and the municipal healthcare movement in the context of the 1970s and 1980s, and its social, politic and innovative power in the democratic reconstruction of the day. It then notes that the implementation of the constitutional guidelines, regulated in 1990 by Laws 8080/90 and 8142/90, has been characterized in the last 22 years by four major and mounting obstacles imposed by State policy on all governments: federal underfunding; federal subsidies to the private health plan market; resistance to reform of the State management structure of service provision; and the handing over of administration of public facilities to private entities. The Brazilian Unified Health System (SUS) included half the population that was once excluded in the public health system, though these obstacles keep the coverage of primary care focused below the poverty line and with poor resolution. The conclusion drawn is that the real policy of the state for healthcare in the past 22 years has prioritized the creation and expansion of the private health plan market for consumer rights, and relegated the effectiveness of constitutional guidelines for civic human rights to second place.

    Glutathione S-transferases (GSTs) play a key role in detoxification of xenobiotics in organisms. However, their other functions, especially response to the natural toxin cantharidin produced by beetles in the Meloidae and Oedemeridae families, are less known. We obtained GST cDNAs from three sources: Cydia pomonella (CpGSTd1), Sus scrofa (SsGST?1), and Triticum aestivum (TaGSTf3). The predicted molecular mass is 24.19, 25.28 and 24.49 kDa, respectively. These proteins contain typical N-terminal and C-terminal domains. Recombinant GSTs were heterologously expressed in Escherichia coli as soluble fusion proteins. Their optimal activities are exhibited at pH 7.0-7.5 at 30 °C. Activity of CpGSTd1 is strongly inhibited by cantharidin and cantharidic acid, but is only slightly suppressed by the demethylated analog of cantharidin and cantharidic acid. Enzymatic assays revealed that cantharidin has no effect on SsGST?1 activity, while it significantly stimulates TaGSTf3 activity, with an EC50 value of 0.3852 mM. Activities of these proteins are potently inhibited by the known GST competitive inhibitor: S-hexylglutathione (GTX). Our results suggest that these GSTs from different sources share similar structural and biochemical characteristics. Our results also suggest that CpGSTd1 might act as a binding protein with cantharidin and its analogs. PMID:25640718

    The article outlines the development and initial validation of a Social Vulnerability Index (SVI) including five social determinants of risk to health and demonstrates its application in the financing of primary care by the Unified Health System (SUS) in the State of Rio Grande do Sul. Municipal indicators of vulnerability relating to poverty and population dispersion were obtained from the 2010 population census of the Brazilian Institute of Geography and Statistics. Both exploratory and confirmatory factor analysis suggests that the five items can constitute a reliable and acceptable measurement scale. The SVI-5 was then generated based on the first main component, measuring municipal inequalities in social vulnerability relating to poverty and population in the territory in Z-scores. The external validity of SVI-5 was examined in relation to health outcomes using DATASUS 2007-2011 data, revealing that infant mortality and hospitalizations for conditions treatable by primary care are greater in more vulnerable municipalities The results suggest that the SVI-5 is a valid measure of inequalities in social vulnerability between municipalities, applicable to socially equitable policies in health.

    Telemetric monitoring of physiologic parameters in animal models is a critical component of chemical and biologic agent studies. The long-term collection of neurobehavioral and other physiologic data can require larger telemetry devices. Furthermore, such devices must be implanted in a location that is safe, well-tolerated, and functional. Göttingen minipigs (Sus scrofa domesticus) present an ideal large animal model for chemical agent studies due to their relatively small size, characterized health status, and ease of training and handling. We report an effective approach to implanting a novel device to measure transthoracic impedance to approximate respiratory tidal volume and rate in Suidae. We tested the approach using 24 male Göttingen minipigs. A ventral midline abdominal incision extending from the umbilicus to the prepuce was followed by a paramedian incision of the parietal peritoneum and dorsal blunt dissection to create a retroperitoneal pocket. The device was anchored inside the pocket to the internal abdominal musculature with 3-0 nonabsorbable suture, biopotential leads were routed through the abdominal musculature, and the pocket was closed with 3-0 absorbable suture. Paired biopotential leads were anchored intermuscularly at the level of the seventh rib midway between spine and sternum bilaterally to provide surrogate data for respiratory function. Postoperative recovery and gross pathology findings at necropsy were used to assess safety and refine the surgical procedure. Results demonstrated that this procedure permitted effective monitoring of complex physiologic data, including transthoracic impedance, without negatively affecting the health and behavior of the animals.

    Globalisation, in terms of the rapid and free movement of people, animals and food, has created a new paradigm, increasing the range and rate of distribution of many pathogens. In the present study, Torque teno sus viruses (TTSuVs) have been used as a model to evaluate the effects of global trade on viral heterogeneity, and how the movement of live pigs can affect the distribution and composition of virus populations. Seventeen countries from different parts of the world have been screened for TTSuV1 and TTSuvV2. High levels of genetic diversity have been found as well as two new TTSuV subtypes. A small fraction of this diversity (<5%) was related with spatial structure; however the majority (>50%) was best explained by the exchange of live pigs among countries, pointing to the direct relationship between the movement of hosts and the diversity of their accompanying viruses. Taking TTSuVs as sentinels, this study revealed that the distribution and diversity of comensal microflora in live animals subjected to global trade is shaped by the commercial movements among countries. In the case of TTSuVs, it appears that commercial movements of animals are eroding the genetic composition of the virus populations that may have been present in pig herds since their domestication.

    Non-tuberculous mycobacteria (NTM) are widely distributed in the environment, particularly in wet soil, marshland, rivers or streams, but also are causative agents of a wide variety of infections in animals and humans. Little information is available regarding the NTM prevalence in wildlife and their effects or significance in the bovine tuberculosis (bTB) epidemiology and diagnosis. This research shows the most frequently NTM isolated in lymph nodes of wild boar (Sus scrofa) from southern Spain, relating the NTM presence with the individual characteristics, the management of animals and the possible misdiagnosis of Mycobacterium bovis in concurrent infections. A total of 219 NTM isolates were obtained from 1249 wild boar mandibular lymph nodes sampled between 2007 and 2011. All but 75 isolates were identified by the PCR-restriction analysis-hsp65, and a partial sequencing of the 16S rDNA was carried out to identify the rest of the isolates. Results showed that Mycobacterium chelonae was the most frequently isolated NTM specie (133 isolates, 60.7%), followed by Mycobacterium avium (24 isolates, 11%). No relation was found regarding sex, body condition and management, but M. chelonae was more frequently detected in adults, whereas M. avium was more prevalent in subadults. The high NTM prevalence observed in the studied wild boar populations could make difficult the bTB diagnostic. PMID:23895110

    Two important questions in bioacoustics are whether vocal repertoires of animals are graded or discrete and how the vocal expressions are linked to the context of emission. Here we address these questions in an ungulate species. The vocal repertoire of young domestic pigs, Sus scrofa, was quantitatively described based on 1513 calls recorded in 11 situations. We described the acoustic quality of calls with 8 acoustic parameters. Based on these parameters, the k-means clustering method showed a possibility to distinguish either two or five clusters although the call types are rather blurred than strictly discrete. The division of the vocal repertoire of piglets into two call types has previously been used in many experimental studies into pig acoustic communication and the five call types correspond well to previously published partial repertoires in specific situations. Clear links exist between the type of situation, its putative valence, and the vocal expression in that situation. These links can be described adequately both with a set of quantitative acoustic variables and through categorisation into call types. The information about the situation of emission of the calls is encoded through five call types almost as accurately as through the full quantitative description. PMID:23967251

    Authors report results emerging from gastric content analysis from n. 96 wild boars hunted in Sardinia isle, during the hunting tide (2001-2005), from November to January. Mean pH of the gastric content was 3.77 +/- 0.69. Mean total capacity (TC) of each stomach was 1702 +/- 680 g. Mean Stuff ratio (CW/TC) between the content weight (CW) and stomachs TC was 0.45. Food categories found in animal stomachs were: 19 categories of vegetal species (Allium spp., Arbutus unedo, Arisarum vulgare, Avena fatua, Avena sativa, Castanea sativa, Ceratonia siliqua, Chamaerops umilis, Cichorium intybus, Hordeum sativum, Juniperus oxycedrus, Myrtus communis, Olea europea, Pirus amygdaliformis, Pistacia lentiscus, Quercus spp., Rhamnus alaternus, Triticum durum, Zea mais); 11 categories of animal species (Agriotes lineatus, Apodemus sylvaticus dicrurus, Chalcides chalcides, Chalcides ocellatus tiligugu, Crematogaster scutellaris, Forficula auricularia, Helix aspersa, Lumbricus terrestris, Ovis aries, Podarcis tiliguerta tiliguerta, Scolopendra cingulata); three categories were identified in general terms (insects larvae, hairs of mammals, feathers of birds). Food categories found in the stomach contents of Sus scrofa meridionalis confirm observations by other researchers who report the prevalence of vegetables in spite of animal food sorts in the wild boar diet in Italian regions.

    In order to improve surface glossiness of stainless steel strip in tandem cold rolling, experimental research on micro-pit defects of SUS 430 ferrite stainless steel was investigated in laboratory. The surface morphology of micro-pit defects was observed by SEM. The effects of micro-pit defects on rolling reduction, roll surface roughness and emulsion parameters were analyzed. With the pass number increasing, the quantity and surface of micro-pit defects were reduced, uneven peak was decreased and gently along rolling direction, micro-pit defects had equally distributed tendency along tranverse direction. The micro-pit defects were increased with the roll surface roughness increase. The defects ratio was declined with larger gradient at pass number 1 to 3, but gentle slope at pass number 4 to 5. The effects of temperature 55° and 63°, concentration 3% and 6% of emulsion on micro-pit effects had not obvious difference. Maintain of micro-pit was effected by rolling oil or air in the micro-pit, the quality of oil was much more than the air in the micro-pit in lubrication rolling.

    Diamond-like carbon (DLC) films were deposited on stainless steel (SUS), titanium (Ti) and nickel titanium (Ni-Ti) substrates using a radiofrequency plasma chemical vapour deposition method. Prior to DLC coating, the substrates were exposed to O2 and N2 plasma to enhance the adhesion strength of the DLC film to the substrate. After the plasma pre-treatment, the chemical composition and the wettability of the substrate surface was investigated by X-ray photoelectron spectroscopy (XPS) and water contact angle measurement, respectively. A pull-out test and a ball-on-disc test were carried out to evaluate the adhesion strength and the wear properties of the DLC-coated substrates. The XPS results showed that the N2 and O2 plasma pre-treatment produced nitride and oxide on the substrate surfaces, such as TiO2, TiO, Fe2O3, CrN and TiNO. In the pull-out test, the adhesion strengths of the DLC film to the SUS, Ti and Ni-Ti substrates were improved with the plasma pre-treatment. In the ball-on-disc test, the DLC coated SUS, Ti and Ni-Ti substrates without the plasma pre-treatment showed severe film failure following the test. The DLC coated SUS and Ni-Ti substrates with the N2 plasma pre-treatment showed good wear resistance, compared with that with the O2 plasma pre-treatment. PMID:20448301

    Samples were collected from 203 wild boars (Sus scrofa) hunted in Baden-Wurtemburg, Germany from November-January 2008 and 2009. Samples from the lung and tonsil were analyzed by quantitative polymerase chain reaction (qPCR) for porcine reproductive and respiratory syndrome virus (PRRSV) type 1 (European type) and type 2 (American type). A qPCR to detect porcine circovirus type 2 (PCV2)-specific genome was performed on tissue homogenates including lung, tonsils, and inguinal lymph nodes. Serum samples were tested for antibodies against PRRSV and PCV2 by enzyme-linked immunosorbent assay (ELISA). No PRRSV was detected in any of the 203 samples and one sample had detectable antibodies against PRRSV. We detected PCV2 in organ materials from 103 wild boars with a prevalence of 50.7%. The number of wild boars positive for PCV2 by PCR varied according to the population density of wild boars among woodlands. More positive samples were detected in woodlands with a high density of wild boars. We found no correlation between the number of PCV2-positive wild boars and the density of domestic pigs in the surrounding area. The number of wild boars positive for antibodies against PCV2 by the INGEZIM Circovirus IgG/IgM test kit was low (53 sera positive for IgG- and three sera positive for IgM-antibodies) in comparison to the higher positive results from the INGEZIM CIRCO IgG test kit (102 positive and 12 inconclusive results).

    An approach to combine a friction heat input model with a non-steady heat conduction analysis has enabled a numerical simulation of a heat input and a transient temperature distribution in friction welding processes. This report describes the result obtained by applying this approach to the friction welding process of two similar materials of S25C carbon steel or SUS304 stainless steel. When base metals are different, the friction heat input model and the thermophysical property data are changed depending on a quality of base metal. Comparison between a calculated result and an experimental result was carried out, and appropriateness of this approach was examined. Furthermore, a difference of temperature distribution in friction welding region with the difference of thermophysical property of base metal was examined, and also the heat-affected zone was investigated. As a result, it was verified that this approach could simulate a characteristic of a welding process in brake-type friction welding. And the calculated results agreed with the experimental results on a difference of quantity of heat input to be caused by a difference of a friction welding condition. A difference of a temperature history caused in a different base metal appeared to be estimated from a calculated result, and it was confirmed that this approach was appropriate. The width of heat-affected zone was estimated by an calculated result of the maximum temperature distribution in the vicinity of friction surface by using this approach combining a friction heat input model with a non-steady heat conduction analysis.

    The wild boar (Sus scrofa) is one of the most widely distributed mammals in Europe. Its demography was affected by various events in the past and today populations are increasing throughout Europe. We examined genetic diversity, structure and population dynamics of wild boar in Central and Eastern Europe. MtDNA control region (664 bp) was sequenced in 254 wild boar from six countries (Poland, Hungary, Belarus, Ukraine, Moldova and the European part of Russia). We detected 16 haplotypes, all known from previous studies in Europe; 14 of them belonged to European 1 (E1) clade, including 13 haplotypes from E1-C and one from E1-A lineages. Two haplotypes belonged respectively to the East Asian and the Near Eastern clade. Both haplotypes were found in Russia and most probably originated from the documented translocations of wild boar. The studied populations showed moderate haplotype (0.714±0.023) and low nucleotide diversity (0.003±0.002). SAMOVA grouped the genetic structuring of Central and Eastern European wild boar into three subpopulations, comprising of: (1) north-eastern Belarus and the European part of Russia, (2) Poland, Ukraine, Moldova and most of Belarus, and (3) Hungary. The multimodal mismatch distribution, Fu's Fs index, Bayesian skyline plot and the high occurrence of shared haplotypes among populations did not suggest strong demographic fluctuations in wild boar numbers in the Holocene and pre-Holocene times. This study showed relatively weak genetic diversity and structure in Central and Eastern European wild boar populations and underlined gaps in our knowledge on the role of southern refugia and demographic processes shaping genetic diversity of wild boar in this part of Europe.

    The lack of suitable target vessels remains a challenge for aortocoronary bypass grafting in end-stage coronary heart disease. This study aimed to investigate the arterialization of cardiac veins as an alternative myocardial revascularization strategy in an experimental long-term model in pigs. Selective retrograde perfusion of a coronary vein (aorta to coronary vein bypass, retrobypass) before ligation of the ramus interventricularis paraconalis (equivalent to the left anterior descending artery in humans) was performed in 20 German Landrace pigs (Sus scrofa domestica). Retroperfusion of the left anterior descending vein was performed in 10 pigs (RP+) but not in the other 10 (RP–), and the vena cordis magna was ligated (L+) in 5 pigs in each of these groups but left open (L–) in the remaining animals. Hemodynamic performance (for example, cardiac output) was significantly better in the group that underwent selective retroperfusion with proximal ligation of vena cordis magna (RP+L+; 4.1 L/min) compared with the other groups (RP+L–, 2.5 L/min; RP–L+, 2.2 L/min; RP–L–, 1.9 L/min). Long-term survival was significantly better in RP+L+ pigs (112 ± 16 d) than in all other groups. Histologic follow-up studies showed significantly less necrosis in the RP+L+ group compared with all other groups. Venous retroperfusion is an effective technique to achieve long-term survival after acute occlusion of the left anterior descending artery in a pig model. In this model, proximal ligation of vena cordis magna is essential. PMID:21535926

    To investigate pseudorabies-virus (PrV) -antibody and viral-DNA prevalence, we collected blood, nasal and genital swabs, and tonsillar and lymph-node tissue samples from 139 wild boars (Sus scrofa; 39 piglets, 30 juveniles, and 70 adults), during the hunting season of 2010-2011 in Tuscany, Central Italy. We performed immunohistochemistry with anti-PrV monoclonal antibodies on selected tissue samples. Forty-three of 139 (30.9%) boars were PrV-antibody positive and a 1,954-base-pair PrV-specific product was amplified from nine nasal (6.5%) and 26 genital (18.7%) swabs. Sequence analysis of PrV-positive PCR products revealed identity scores of 99-100% with Suid herpesvirus 1 strain Becker (JF797219) and confirmed the identification of PrV DNA in tested swabs. There was significantly higher antibody prevalence in adults than in juveniles and in piglets than in juveniles. The prevalence of viral DNA was significantly higher in genital swabs than in nasal specimens. The percentage of positive nasal swabs did not differ among age classes. Piglets had a higher percentage of PCR-positive genital swabs than juvenile and adult subjects (30.8% vs. 13.3% and 14.3%, respectively). Results confirmed that PrV infection is widespread in the wild boar population in the study area. The presence of anti-PrV antibodies and of the PrV virus in piglets could be related to vertical transmission of the virus. This hypothesis was also supported by a higher presence of viral genome in genital swabs than in nasal swabs. This field study supports the importance of vertical transmission of PrV, and the high prevalence of virus in genital swabs supports venereal transmission in adult feral boars. PMID:24779458

    Los estados Rydberg moleculares han suscitado en los últimos años un creciente interés entre los espectroscopistas experimentales, motivado en parte por el desarrollo de nuevas técnicas espectroscópicas capaces de investigar estos estados altamente excitados electrónicamente. Los procesos de fotoabsorción que implican estados Rydberg en los derivados halogenados del metano son de gran importancia, debido a su abundancia en la atmósfera y a sus implicaciones medioambientales. Por ello, la obtención de datos relativos a sus fuerzas de oscilador es de gran interés. En este trabajo se aborda el estudio de dichas propiedades para las moléculas isovalentes CF3Cl y CF3Br. Ambas moléculas presentan idéntica estructura electrónica para el estado fundamental por lo que se espera que sus espectros Rydberg presenten grandes similitudes, en ausencia de perturbaciones. Por ello y dada la escasez de datos relativos a fuerzas de oscilador, hemos establecido la corrección de nuestros resultados en base a las analogías esperadas en las intensidades espectrales correspondientes a transiciones análogas. Por otro lado, Novak y col. [1] han encontrado experimentalmente un marcado carácter atómico en el espectro correspondiente a estas moléculas, siendo muy similar a los de los átomos de Cl y Br. Por ello en el presente trabajo, además de establecer la comparación entre ambas moléculas hemos buscado las similitudes con sus respectivos halógenos. Los cálculos relativos a las especies moleculares se han realizado utilizando la Metodología Molécular de Orbítales de Defecto Cuántico (MQDO) [2], mientras que para el estudio de los átomos de Cl y Br se empleó la versión relativista del método (RQDO) [3].

    This article describes the code SusHi (for "Supersymmetric Higgs") [108] which calculates the cross sections pp/pp ¯ ??+X in gluon fusion and bottom-quark annihilation in the SM and the MSSM, where ? is any of the neutral Higgs bosons within these models. Apart from inclusive cross sections up to NNLO QCD, differential cross sections with respect to the Higgs transverse momentum pT and (pseudo-)rapidity y(?) can be calculated through NLO QCD. In the case of gluon fusion, SusHi contains NLO QCD contributions from the third family of quarks and squarks, NNLO corrections due to top-quarks, approximate NNLO corrections due to top-squarks, and electro-weak effects. It supports various renormalization schemes for the sbottom sector and the bottom Yukawa coupling, as well as resummation effects of higher order tan?-enhanced sbottom contributions. SusHi provides a link to FeynHiggs for the calculation of the Higgs masses.

    In many temperate regions, ice ages promoted range contractions into refugia resulting in divergence (and potentially speciation), while warmer periods led to range expansions and hybridization. However, the impact these climatic oscillations had in many parts of the tropics remains elusive. Here, we investigate this issue using genome sequences of three pig (Sus) species, two of which are found on islands of the Sunda-shelf shallow seas in Island South-East Asia (ISEA). A previous study revealed signatures of interspecific admixture between these Sus species (Genome biology,14, 2013, R107). However, the timing, directionality and extent of this admixture remain unknown. Here, we use a likelihood-based model comparison to more finely resolve this admixture history and test whether it was mediated by humans or occurred naturally. Our analyses suggest that interspecific admixture between Sunda-shelf species was most likely asymmetric and occurred long before the arrival of humans in the region. More precisely, we show that these species diverged during the late Pliocene but around 23% of their genomes have been affected by admixture during the later Pleistocene climatic transition. In addition, we show that our method provides a significant improvement over D-statistics which are uninformative about the direction of admixture. PMID:25294645

    Abstract Tularemia outbreaks in humans have recently been reported in many European countries, but data on the occurrence in the animal population are scarce. In North America, seroconversion of omnivores and carnivores was used as indicator for the presence of tularemia, for the European fauna, however, data are barely available. Therefore, the suitability of wild boars (Sus scrofa) and red foxes (Vulpes vulpes) as indicators for the circulation of F. tularensis in Germany was evaluated. Serum samples from 566 wild boars and 457 red foxes were collected between 1995 and 2012 in three federal states in Central Germany (Hesse, Saxony-Anhalt, and Thuringia). The overall rate of seropositive animals was 1.1% in wild boars and 7.4% in red foxes. In conclusion, serological examination of red foxes is recommended, because they can be reliably used as indicator animals for the presence of F. tularensis in the environment. PMID:24359418

    Livestock was often released onto remote Southern Ocean islands as a food source for shipwreck survivors during the industrial whaling and sealing era. Although animals were put ashore at nearby Isles Kerguelen and Crozet, the historical records make no mention of domesticated livestock ever being set ashore at Heard Island between 1855 and 1882. Here we report a pig ( Sus scrofa) mandible discovered amongst other bones and artefacts in an `elephanters' midden found at Spit Bay, Heard Island. The find provides very strong evidence a live pig was shipped ashore and eaten as part of the sealers meagre provisions. Archaeological investigations of middens at other sealing locations could produce new insights into the dietary habits of these men.

    Intergranular stress corrosion cracking (IGSCC) in type SUS304 stainless steels, tested under pressurized water reactor (PWR) primary water conditions, has been characterized with unprecedented spatial resolution using scanning electron microscopy (SEM) and novel low-energy (?3 kV) energy dispersive X-ray spectroscopy (EDX). An advancement of the large area silicon drift detector (SDD) has enhanced its sensitivity for X-rays in the low-energy part of the atomic spectrum. Therefore, it was possible to operate the SEM at lower accelerating voltages in order to reduce the interaction volume of the beam with the material and achieve higher spatial resolution and better signal-to-noise ratio. In addition to studying the oxide chemistry at the surface of intergranular stress corrosion cracks, the technique has proven capable of resolving Ni enrichment ahead of some crack tips. Active cracks could be distinguished from inactive ones due to the presence of oxides in the open crack and Ni-rich regions ahead of the crack tip. Furthermore, it has been established that SCC features can be better resolved with low-energy (3 kV) than high-energy (12 kV) EDX. The low effort in sample preparation, execution and data analysis makes SEM the ideal tool for initial characterization and selection of the most important SCC features such as dominant cracks and interesting crack tips, later to be studied by transmission electron microscopy (TEM) and atom probe tomography (APT).

    In this report we describe for the first time the detection of Sarcoptes scabiei type suis mites on domestic pigs in Israel and examine its genetic variation compared with S. sabiei from other hosts. Microscopic examination of skin samples from S. scabiei-infested pigs (Sus scrofa domesticus) revealed all developmental stages of S. scabiei. To detect genetic differences between S. scabiei from different hosts, samples obtained from pig, rabbits (Orictolagus cuniculus), fox (Vulpes vulpes), jackal (Canis aureus) and hedgehog (Erinaceus concolor) were compared with GenBank-annotated sequences of three genetic markers. Segments from the following genes were examined: cytochrome C oxidase subunit 1 (COX1), glutathione-S-transferase 1 (GST1), and voltage-sensitive sodium channel (VSSC). COX1 analysis did not show correlation between host preference and genetic identity. However, GST1 and VSSC had a higher percentage of identical sites within S. scabiei type suis sequences, compared with samples from other hosts. Taking into account the limited numbers of GST1 and VSSC sequences available for comparison, this high similarity between sequences of geographically-distant, but host-related populations, may suggest that different host preference is at least partially correlated with genetic differences. This finding may help in future studies of the factors that drive host preferences in this parasite. PMID:26002310

    The expansion of feral swine (Sus scrofa) populations into new geographic regions is of concern not only due to increased range but also because they carry diseases and parasites that pose a threat to humans, livestock, and wildlife into new areas. Recently, emerging feral swine populations have been reported in the northeastern US and due to their adaptive nature will likely continue to spread. During 2009-2012, 49 feral swine were removed from three counties in New Hampshire. Of these, serum samples were submitted from 34 for disease surveillance testing. One of the feral swine was antibody-positive for pseudorabies virus (PRV) making it the first documented infection in feral swine in New Hampshire. Infestations of winter tick (Dermacentor albipictus) were also documented on two of the feral swine which had only been reported previously on feral swine in Texas. Feral swine may not only serve as an important host for an economically important commercial swine pathogen like PRV, but they could also increase host diversity for parasites such as the winter tick, a species that can regionally impact moose (Alces alces) survival. These findings warrant further investigation of expanding and established feral swine populations in New Hampshire as pathogen hosts and support continued effort to reduce numbers or regionally eradicate feral swine.

    As feral swine (Sus scrofa) populations expand their range and the opportunity for feral swine hunting increases, there is increased potential for disease transmission that may impact humans, domestic swine, and wildlife. From September 2007 to March 2010, in 13 North Carolina, USA, counties and at Howell Woods Environmental Learning Center, we conducted a serosurvey of feral swine for Brucella suis, pseudorabies virus (PRV), and classical swine fever virus (CSFV); the samples obtained at Howell Woods also were tested for porcine circovirus type 2 (PCV-2). Feral swine serum was collected from trapped and hunter-harvested swine. For the first time since 2004 when screening began, we detected B. suis antibodies in 9% (9/98) of feral swine at Howell Woods and <1% (1/415) in the North Carolina counties. Also, at Howell Woods, we detected PCV-2 antibodies in 59% (53/90) of feral swine. We did not detect antibodies to PRV (n=512) or CSFV (n=307) at Howell Woods or the 13 North Carolina counties, respectively. The detection of feral swine with antibodies to B. suis for the first time in North Carolina warrants increased surveillance of the feral swine population to evaluate speed of disease spread and to establish the potential risk to commercial swine and humans.

    Hepatitis E virus (HEV) is a member of the genus Hepevirus within the family Hepeviridae. Hepatitis E is recognized as a zoonosis, and swine and wild boars (Sus scrofa) are known reservoirs of HEV infection. The aim of this study was to investigate the presence of HEV in wild boars and hunters exposed to infection in central Italy (Latium region). During the hunting season, blood samples were collected from 228 wild boars and 20 hunters. The seroprevalence of HEV infection was determined using a commercial enzyme-linked immunosorbent assay, previously validated for use in man, pigs and wild boars. The estimated HEV seroprevalence in wild boars and in hunters was 40.7% (93/228; 95% confidence interval [CI] 34.4-47.1%) and 25% (5/20; 95% CI 6.1-43.9%), respectively. Liver samples were collected from the boars and HEV RNA was detected by nested reverse transcriptase polymerase chain reaction. Fifty-five of 164 tested wild boar liver samples (33.5%; 95% CI 26.2-40.7%) and three of 20 (15.0%; 95% CI 1.3-28.7%) tested human serum samples were positive for HEV RNA. Phylogenetic analysis of the nucleotide sequences obtained from PCR products indicated that the HEV strains present in wild boars and the human population all belonged to genotype 3, supporting the zoonotic role of wild boars in the spread of HEV infection.

    In ischemic hearts, venous retroperfusion is a potential myocardial revascularization strategy. This study aimed to refine the technical and functional aspects of a pig model of acute myocardial infarction and retroperfusion with respect to the azygos connection. Global retroperfusion after ligation of the ramus interventricularis paraconalis (equivalent to the left anterior descending artery in humans) was performed in 16 Landrace pigs (Sus scrofa domestica). Coronary sinus perfusion was performed in 8 pigs (P+) but not in the other 8 (P–), and the azygos vein was ligated (L+) 4 of the 8 pigs in each of these groups but left open (L–) in the remaining animals. Hemodynamic performance (for example, cardiac output, stroke volume) was significantly better in P+L+ pigs that underwent coronary sinus perfusion with ligation of the azygos vein compared with all other animals. In addition, troponin I release was significant lower in P+L+ pigs (1.7 ± 1.3 ng/mL) than in P–L– (5.47 ± 2.1 ng/mL), P–L+ (6.63 ± 2.4 ng/mL), and P+L– (4.81 ± 2.3 ng/mL) pigs. Effective retrograde flow and thus hemodynamic stability was achieved by ligation of the azygos vein. Therefore, experiments focusing on global retroperfusion will benefit from effective inhibition of the blood flow through the azygos vein. PMID:20158947

    Background As a result of rapidly growing human populations, intensification of livestock production and increasing exploitation of wildlife habitats for animal agriculture, the interface between wildlife, livestock and humans is expanding, with potential impacts on both domestic animal and human health. Wild animals serve as reservoirs for many viruses, which may occasionally result in novel infections of domestic animals and/or the human population. Given this background, we used metagenomics to investigate the presence of viral pathogens in sera collected from bushpigs (Potamochoerus larvatus), a nocturnal species of wild Suid known to move between national parks and farmland, in Uganda. Results Application of 454 pyrosequencing demonstrated the presence of Torque teno sus virus (TTSuV), porcine parvovirus 4 (PPV4), porcine endogenous retrovirus (PERV), a GB Hepatitis C–like virus, and a Sclerotinia hypovirulence-associated-like virus in sera from the bushpigs. PCR assays for each specific virus combined with Sanger sequencing revealed two TTSuV-1 variants, one TTSuV-2 variant as well as PPV4 in the serum samples and thereby confirming the findings from the 454 sequencing. Conclusions Using a viral metagenomic approach we have made an initial analysis of viruses present in bushpig sera and demonstrated for the first time the presence of PPV4 in a wild African Suid. In addition we identified novel variants of TTSuV-1 and 2 in bushpigs. PMID:22967311

    In this study, multi-drug resistant Escherichia coli Sw1 (E. coli Sw1) and active lytic phage EcSw was isolated from feces samples of Sus scrofa domesticus (piglet) suffering from diarrhea. Transmission electron microscopy (TEM) indicated that isolated EcSw belongs to the Myoviridae family with an icosahedral head (80 ± 4) and a long tail (180 ± 5 nm). The EcSw phage genome size was estimated to be approximately 75 Kb of double-stranded DNA (dsDNA). Phage dynamic studies show that the latent period and burst size of EcSw were approximately 20 min and 28 PFU per cell, respectively. Interestingly, the EcSw phage can tolerate a wide range of environmental conditions, such as temperature, pH and ions (Ca(2+) and Mg(2+)). Furthermore, genome sequence analysis revealed that the lytic genes of the EcSw phage are notably similar to those of enterobacteria phages. In addition, phage-antibiotic synergy has notable effects compared with the effects of phages or antibiotics alone. Inhibition of E. coli Sw1 and 0157:H7 strains showed that the limitations of host specificity and infectivity of EcSw. Even though, it has considerable potential for phage therapy for handling the problem of the emergence of multidrug resistant pathogens. PMID:25805216

    The basic helix-loop-helix (bHLH) transcription factors are one of the largest families of gene regulatory proteins and play crucial roles in genetic, developmental and physiological processes in eukaryotes. Here, we conducted a survey of the Sus scrofa genome and identified 109 putative bHLH transcription factor members belonging to super-groups A, B, C, D, E, and F, respectively, while four members were orphan genes. We identified 6 most significantly enriched KEGG pathways and 116 most significant GO annotation categories. Further comprehensive surveys in human genome and other 12 medical databases identified 72 significantly enriched biological pathways with these 113 pig bHLH transcription factors. From the functional protein association network analysis 93 hub proteins were identified and 55 hub proteins created a tight network or a functional module within their protein families. Especially, there were 20 hub proteins found highly connected in the functional interaction network. The present study deepens our understanding and provided insights into the evolution and functional aspects of animal bHLH proteins and should serve as a solid foundation for further for analyses of specific bHLH transcription factors in the pig and other mammals.

    We determined prevalence of antibody to selected viral pathogens important for domestic pigs and livestock in 556 wild boar (Sus scrofa) sera collected during 2005-06 and 2009-10 in four counties in Croatia. These counties account for an important part of the Croatian commercial pig production and have a high density of wild boars. Samples were tested for antibodies to porcine parvovirus (PPV), Aujeszky's disease virus (ADV), porcine circovirus type 2 (PCV2), swine influenza virus, porcine respiratory and reproductive syndrome virus (PRRSV), porcine respiratory coronavirus (PRCV), transmissible gastroenteritis virus, and swine vesicular disease virus (SVDV). Antibodies to all of the infectious pathogens except SVDV were detected. There was a statistically significant difference in prevalence between the two periods for PPV, ADV, PCV2, PRRSV, and PRCV, with a higher prevalence of PPV and ADV in the 2009-10 period (P<0.05). During the same period, the prevalence of PCV2, PRRSV, and PRCV was lower (P<0.05). Our results provide information on the current disease exposure and health status of wild boars in Croatia and suggest that wild boars may act as a reservoir for several pathogens and a source of infection for domestic pigs and other livestock as well as humans, especially for ADV.

    Previous studies have shown that apes, dogs and horses seem to be able to attribute attentive states to humans. Subjects had to choose between two persons: one who was able to see the animal and one who was not. Using a similar paradigm, we tested a species that does not rely strongly on visual cues, the domestic pig (Sus scrofa domestica). Subjects could choose between two unfamiliar persons, with only one showing attention, in three different conditions (body, head away, body turned - head front). Subjects (n=16) only showed a tendency towards the attentive human in the head away condition. However, by pooling those two conditions where the position of the human head was the only salient cue, we found a significant preference for the attentive person. Moreover, two approach styles could be distinguished - an impulsive style with short response times and a non-impulsive style where response times were relatively long. With the second approach style, pigs chose the attentive person significantly more often than expected by chance level, which was not the case when subjects chose impulsively. These first results suggest that pigs are able to use head cues to discriminate between different attentive states of humans. PMID:23500190

    Feral pigs (Sus scrofa) are an invasive species that disrupt ecosystem functioning throughout their introduced range. In tropical environments, feral pigs are associated with predation and displacement of endangered species, modification of habitat, and act as a vector for the spread of exotic vegetation and disease. Across many parts of their introduced range, the diet of feral pigs is poorly known. Although the remote location and difficult terrain of far north Queensland makes observing feral pig behavior difficult, feral pigs are perceived to seek refuge in World Heritage tropical rainforests and seasonally ‘crop raid’ into lowland sugarcane crops. Thus, identifying how feral pigs are using different components of the landscape is important to the design of management strategies. We used the stable isotope composition of captured feral pigs to determine the extent of rainforest and sugarcane habitat usage. Recently grown hair (basal hair) from feral pigs captured in remote rainforest indicated pigs met their dietary needs solely within this habitat. Stable carbon and nitrogen isotope values of basal hair from feral pigs captured near sugarcane plantations were more variable, with some individuals estimated to consume over 85% of their diet within a sugarcane habitat, while a few consumed as much as 90% of their diet from adjacent forested environments. We estimated whether feral pigs switch habitats by sequentially sampling ?13C and ?15N values of long tail hair from a subset of seven captured animals, and demonstrate that four of these individuals moved between habitats. Our results indicate that feral pigs utilize both sugarcane and forest habitats, and can switch between these resources. PMID:22957029

    We studied the concentration and distribution of (137)Cs and (90)Sr in the bodies of 188 wild boar (Sus scrofa Linnaeus, 1758) taken near the Chernobyl site. Of these, 111 animals were taken in the Alienation Zone, 41 animals were taken in the Permanent Control Zone and 36 animals were taken in the Periodic Control Zone. The samples included muscle and bone (rib) tissues and samples of heart, liver, lungs, kidneys, spleen, genitals and skin. The weight of the samples was 0.5 kg fresh weigh. The average concentration of (137)Cs in the muscles of the wild boar found in the Alienation Zone was 46 ± 10 kBq/kg, in the Permanent Control Zone - 13 ± 3.0 kBq/kg and in the Periodic Control Zone - 0.6 ± 0.1 kBq/kg. The largest concentration of (137)Cs was detected in the muscle tissue and kidneys taken animals. In some samples of muscle tissue it reached more than 660 kBq/kg. The (137)Cs concentrations were also high in heart and spleen up 64.3 kBq/kg and 67.5 kBq/kg - animals from the Alienation Zone and 10.3-10.6 kBq/kg - animals from the Permanent Control zone. The lowest concentration of (137)Cs was found in the lungs and skin of animals. The analyses of (90)Sr concentration in the organs and tissues of the wild boar showed that (90)Sr was concentrated mainly in the bone tissue. The average level of (90)Sr concentration in bone was 17.6 kBq/kg fresh weight animals from the Alienation Zone and 13.47 kBg/kg - animals from the Permanent Control zone. In muscle tissues and organs contained (90)Sr - 30.0-110.0 Bq/kg in the Alienation Zone and 11.0-30.0 Bq/kg in the Permanent Control zone. PMID:23871249

    Using serology and bacterial culture, we determined the prevalence of Brucella spp. and the antibody to Brucella spp. in a feral swine (Sus scrofa) population in proximity to a cattle herd that was culture positive for Brucella abortus and Brucella suis in north-central Texas, USA. During a prospective cross-sectional quantitative study in April 2005, we collected blood and tissue samples from 40 feral swine within a 30-km radius of the infected herd. Serum samples were tested by the Rose Bengal test, particle concentration fluorescence immunoassay, and fluorescence polarization assay. In addition, tissue samples were cultured, and the Brucella species and biovar determined. Four feral swine were Brucella positive by serology, and two were culture positive for B. suis biovar 1. Of the culture-positive swine, one was concurrently antibody and culture positive, and one was culture positive only. The presumptive source of the B. suis infection in the index cattle herd was likely the surrounding feral swine population. Because B. abortus was not cultured from the feral swine, it is unlikely that the source of the B. abortus infection in the index herd originated from the feral swine. Endemic diseases in feral swine populations can pose a disease threat to livestock and a zoonotic risk to humans. PMID:23568896

    The aim of this study was to characterize the composition of follicular fluid (FF) collected from the small and large follicles of three mammalian species, Bos taurus, Sus scrofa domesticus, and Equus ferus caballus, that display distinct ovulatory properties. For each species, five large FF samples and five small FF samples were analyzed using 1H-NMR spectroscopy. The FF metabolic profiles of the three species were very distinct. In cows and mares, the metabolic profiles of large FF and small FF were also very distinct. The concentrations of seventeen identified metabolites differed significantly between the sample groups. In mares, fourteen metabolites were found at much greater concentrations in large FF than in small FF (p<0.05). In cows, four metabolites differed in concentration between the large FF and small FF samples (p<0.05). A common feature of the monovulatory species was that the concentrations of ?- and ?-glucose were much greater in large FF compared with small FF (p<0.05). Sow FF was characterized by the apparent absence of citrate (detected in cow and mare FF), and the presence of succinate (not detected in cow and mare FF). Another obvious difference between species was the concentration of lactate, which was minimal in mare FF compared with cow and sow FF (p<0.05). The findings provide valuable insights into reproductive physiology broadly, and indicate that the activities of central metabolic enzymes differ enormously between these species. Future investigations into species-specific differences in follicle metabolism would increase our understanding of the processes critical to folliculogenesis and the acquisition of oocyte developmental competence.

    Torque teno sus viruses (TTSuV1-2), members of the newly established family Anelloviridae are considered non-pathogenic emerging viral agents of Suidae species. However, the genetic diversity, phylogeny and evolutionary processes responsible for the emergence and spread of TTSuVs in wild boars remain poorly understood. Here we implemented phylogenetic and evolutionary analyses to address key questions on the genetic diversity, evolutionary scenario and spatio-temporal dynamics of emerging TTSuVs in wild boars of the Western region (Transylvania) of Romania. High levels of genetic diversity of wild boar origin TTSuV1-2 have been found as well as a new TTSuV1 genotype and several new subtypes. Phylogenies suggest that several wild boar viral strains in both TTSuV species are likely to have emerged from a well-defined ancestor approximately 40 (TTSuV1) and 18 (TTSuV2) years ago and showed independent evolutionary trajectories. Bayesian phylogeography showed an intense flow of viral strains throughout the Transylvanian counties possibly related to wild host migrations, facilitating the rapid spread of TTSuVs. The intra-genotype and inter- and intrahost level recombination, intense spatio-temporal viral flow and the positively selected sites found in the ORF2 genes should be considered important driving forces shaping TTSuVs evolution. The first reported rates of nucleotide substitution for porcine anelloviruses, estimated to be 5.29-5.51 × 10(-4)subs site(-1)year(-1), are in line with those measured previously for mammalian ssDNA viruses and RNA viruses. These high evolutionary rates of TTSuVs, independent of recombination, are reflections of adaptive evolution, an important factor in the emergence of novel viral variants which may explain their ability to emerge in Suidae hosts.

    In the absence of supportive care, exposing Göttingen minipigs to ?-radiation doses of less than 2 Gy achieves lethality due to hematopoietic acute radiation syndrome. Doses of 2 to 5 Gy are associated with an accelerated hematopoietic syndrome, characterized by villus blunting and fusion, the beginning of sepsis, and a mild transient reduction in plasma citrulline concentration. We exposed male Göttingen minipigs (age, 5 mo; weight, 9 to 11 kg) to ?-radiation doses of 5 to 12 Gy (total body; 60Co, 0.6 Gy/min) to test whether these animals exhibit classic gastrointestinal acute radiation syndrome (GI-ARS). After exposure, the minipigs were monitored for 10 d by using clinical signs, CBC counts, and parameters associated with the development of the gastrointestinal syndrome. Göttingen minipigs exposed to ? radiation of 5 to 12 Gy demonstrate a dose-dependent occurrence of all parameters classically associated with acute GI-ARS. These results suggest that Göttingen minipigs may be a suitable model for studying GI-ARS after total body irradiation, but the use of supportive care to extend survival beyond 10 d is recommended. This study is the first step toward determining the feasibility of using Göttingen minipigs in testing the efficacy of candidate drugs for the treatment of GI-ARS after total body irradiation.

    Hasta hace poco tiempo, Urano era el único de los Planetas Gigantes que no poseía satélites irregulares. Esto lo diferenciaba del resto de los planetas Gigantes, al igual que la peculiar oblicuidad de su eje de spin. La gran inclinación de su eje de rotación se debe probablemente a una colisión que sufrió el planeta con otro embrión planetario al final del proceso de formación. Esta colisión habría desligado satélites exteriores preexistentes del planeta. Recientemente se han descubierto dos satélites irregulares de Urano, lo que introduce algunas nuevas cotas y condiciones en el escenario de la "Hipótesis de la Gran Colisión" . Los satélites irregulares de Urano tuvieron que ser capturados en una etapa posterior a la del escenario de la Gran Colisión, de no ser así, hubieran sido eyectados del sistema por el impulso impartido con ese gran impacto. En este trabajo, se discuten los posibles mecanismos de captura de los satélites irregulares y se presenta un nuevo posible mecanismo para dicha captura.

    Wild boar are widely distributed throughout the Iberian Peninsula and can carry potentially virulent strains of Streptococcus suis. The objective of this study was to determine the prevalence of S. suis in wild boars from two large geographical regions of Spain. Serotypes 1, 2, 7 and 9 identified were further genetically characterised by virulence-associated genotyping, pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) to determine the population structure of S. suis carried by these animals. Streptococcus suis was isolated from 39.1% of the wild boars examined: serotype 9 was the most frequently isolated (12.5%), followed by serotype 1 (2.5%). Serotype 2 was rarely isolated (0.3%). Eighteen additional serotypes were identified indicating wide diversity of this pathogen within the wild boar population. This heterogeneity was confirmed by PFGE and MLST analyses and the majority of isolates exhibited the virulence-associated genotype mrp-/epf-/sly-. The results of this study highlight that the carriage of S. suis by wild boars is commonplace. However, MLST data indicate that these isolates are not related to prevalent clonal complexes ST1, ST16, ST61 and ST87 typically associated with infection of pigs or humans in Europe. PMID:24726078

    Tail biting in pigs is a major welfare problem within the swine industry. Even though there is plenty of information on housing and management-related risk factors, the biological bases of this behavioral problem are poorly understood. The aim of this study was to investigate a possible link between tail biting, based on behavioral recordings of pigs during an ongoing outbreak, and certain neurotransmitters in different brain regions of these pigs. We used a total of 33 pigs at a farm with a long-standing problem of tail biting. Three equally big behavioral phenotypic groups, balanced for gender and age were selected, the data thus consisting of 11 trios of pigs. Two of the pigs in each trio originated from the same pen: one tail biter (TB) and one tail biting victim (V). A control (C) pig was selected from a pen without significant tail biting in the same farm room. We found an effect of tail biting behavioral phenotype on the metabolism of serotonin and dopamine, with a tendency for a higher 5-HIAA level in the prefrontal cortex (PFC) of TB compared to the other groups, while V pigs showed changes in both serotonin and dopamine metabolism in the striatum (ST) and limbic cortex (LC). Trp:BCAA and Trp:LNAA correlated positively with serotonin and 5-HIAA in the PFC, but only in TB pigs. Furthermore, in both ST and LC, several of the neurotransmitters and their metabolites correlated positively with the frequency of bites received by the pig. This is the first study indicating a link between brain neurotransmission and tail biting behavior in pigs with TB pigs showing a tendency for increased PFC serotonin metabolism and V pigs showing several changes in central dopamine and serotonin metabolism in their ST and LC, possibly due to the acute stress caused by being bitten.

    Sulfated steroids have been traditionally regarded as inactive metabolites. However, they may also serve as precursors for the production of active free steroids in target cells. In this study, we used the boar as a model to study the metabolism, transport, and function of steroid sulfates due to their high production in the porcine testicular-epididymal compartment, of which the role is unknown. To characterize the secretion of free and sulfated steroids, plasma samples were collected from six postpubertal boars over 6 ?h every 20 ?min from the jugular vein. Long-term secretion profiles were also established in seven boars stimulated with human chorionic gonadotropin. To directly characterize the testicular output, samples were collected from superficial testicular arterial and venous blood vessels. Testosterone, androstenedione and sulfated pregnenolone, DHEA, estrone (E1), and estradiol-17? (E2) were determined by liquid chromatography-tandem mass spectrometry. Free E1 and E2 were measured by RIA. Irrespective of a high variability between individuals, the results suggest that i) all steroids assessed are primarily produced in the testis, ii) they exhibit similar profiles pointing to a pulsatile secretion with low frequency (three to five pulses per day), and iii) after synthesis at least a major proportion is immediately released into peripheral circulation. The fact that all steroid sulfates assessed are original testicular products and their high correlations with one another suggest their role as being intermediates of testicular steroidogenesis rather than as being inactivated end products. Moreover, a substantial use of sulfated steroids in porcine testicular steroidogenesis would assign a crucial regulatory role to steroid sulfatase, which is highly expressed in Leydig cells.

    Background In many parts of the developing world, pigs are kept under low-input systems where they roam freely to scavenge food. These systems allow poor farmers the opportunity to enter into livestock keeping without large capital investments. This, combined with a growing demand for pork, especially in urban areas, has led to an increase in the number of small-holder farmers keeping free range pigs as a commercial enterprise. Despite the benefits which pig production can bring to a household, keeping pigs under a free range system increases the risk of the pig acquiring diseases, either production-limiting or zoonotic in nature. This study used Global Positioning System (GPS) technology to track free range domestic pigs in rural western Kenya, in order to understand their movement patterns and interactions with elements of the peri-domestic environment. Results We found that these pigs travel an average of 4,340?m in a 12?hr period and had a mean home range of 10,343?m2 (range 2,937–32,759?m2) within which the core utilisation distribution was found to be 964?m2 (range 246–3,289?m2) with pigs spending on average 47% of their time outside their homestead of origin. Conclusion These are the first data available on the home range of domestic pigs kept under a free range system: the data show that pigs in these systems spend much of their time scavenging outside their homesteads, suggesting that these pigs may be exposed to infectious agents over a wide area. Control policies for diseases such as Taenia solium, Trypanosomiasis, Trichinellosis, Toxoplasmosis or African Swine Fever therefore require a community-wide focus and pig farmers require education on the inherent risks of keeping pigs under a free range system. The work presented here will enable future research to incorporate movement data into studies of disease transmission, for example for the understanding of transmission of African Swine Fever between individuals, or in relation to the life-cycle of parasites including Taenia solium.

  13. Induced pluripotent stem cells from swine (Sus scrofa): why they may prove to be important.

    Three recent papers, published almost simultaneously by different groups, have described the generation of induced pluripotent stem (iPS) cells from the pig, a species whose size, anatomy and physiology render them attractive as clinical models for the human. The approach used in each case was to infect somatic cells with integrating retroviral vectors designed to express four reprogramming genes (POU5F1, SOX2, cMYC and KLF4). The cell lines generated met the standard criteria for pluripotency, including the ability to differentiate along multiple tissue lineages. In most respects, the porcine iPS cells more resembled human embryonic stem cells and human iPS cells than their murine equivalents. Provided such porcine iPS cells can be "personalized" to specific pigs and then coaxed to differentiate along specific lineages, it should be possible to use such animals to test transplantation therapies with iPS cells for safety and efficacy before the procedures are applied to human patients.

    We describe the morphological, biological, and molecular characteristics of Cryptosporidium pig genotype II and propose the species name Cryptosporidium scrofarum n. sp. to reflect its prevalence in adult pigs worldwide. Oocysts of C. scrofarum are morphologically indistinguishable from C. parvum, measuring 4.81–5.96 µm (mean = 5.16) × 4.23–5.29 µm (mean = 4.83) with a length to width ratio of 1.07 ± 0.06 (n = 400). Oocysts of C. scrofarum obtained from a naturally infected pig were infectious for 8-week-old pigs but not 4-week-old pigs. The prepatent period in 8-week-old Cryptosporidium-naive pigs was 4–6 days and the patent period was longer than 30 days. The infection intensity of C. scrofarum in pigs was generally low, in the range 250-4000 oocysts per gram of faeces. Infected pigs showed no clinical signs of cryptosporidiosis and no pathology was detected. Cryptosporidium scrofarum was not infectious for adult SCID mice, adult BALB c mice, Mongolian gerbils (Meriones unguiculatus), southern multimammate mice (Mastomys coucha), yellow-necked mice (Apodemus flavicollis), or guinea pigs (Cavia porcellus). Phylogenetic analyses based on Small subunit rRNA, actin, and heat shock protein 70 gene sequences revealed that C. scrofarum is genetically distinct from all known Cryptosporidium species.

    We present a computer program and underlying model to calculate the electric susceptibility of a gas, which is essential to predict its absorptive and dispersive properties. Our program focusses on alkali-metal vapours where we use a matrix representation of the atomic Hamiltonian in the completely uncoupled basis in order to calculate transition frequencies and strengths. The program calculates various spectra for a weak-probe laser beam in an atomic medium with an applied axial magnetic field. This allows many optical devices to be designed, such as Faraday rotators/filters, optical isolators and circular polarisation filters. Fitting routines are also provided with the program which allows the user to perform optical metrology by fitting to experimental data.

    Ochratoxins are fungal secondary metabolites that may contaminate a broad variety of foodstuffs, such as grains, vegetables, coffee, dried fruits, beer, wine and meats. Ochratoxins are nephrotoxins, carcinogens, teratogens and immunotoxins in rats and are also likely to be in humans. In 2009/2010, a survey of the presence of Ochratoxin A (OTA) in regularly hunted wild boars in the Calabria region of southern Italy detected OTA in 23 animals in the kidney, urinary bladder, liver and muscles: 1.1 ± 1.15, 0.6 ± 0.58, 0.5 ± 0.54 and 0.3 ± 0.26 ?g/kg, respectively. Twelve tissue samples showed levels of OTA higher than the guideline level (1 ?g/kg) established by the Italian Ministry of Health. In five wild boars, gross-microscopic lesions were described for the organs displaying the highest concentrations of OTA determined by HPLC-FLD analysis, i.e., the kidney, liver and urinary bladder.

    2014-01-01

    Background Anaplasma phagocytophilum is a tick-borne pathogen of veterinary and human importance. Both ticks as vectors and vertebrates as reservoir hosts are essential for the cycle maintenance of this bacterium. Currently, the whole range of animal species reservoirs for A. phagocytophilum in natural environment is still unknown. Therefore, the aim of this study was to estimate the prevalence of infection with A. phagocytophilum in the wild boar population in southern Belgium. Results In the frame of a targeted surveillance program, 513 wild boars were sampled during the hunting season 2011. A nested 16S rRNA PCR was used to screen the presence of A. phagocytophilum DNA in spleen of boars. Within 513 samples, 5 (0,97%) were tested PCR positive and identification was confirmed by sequencing. Conclusions This study gives the first insight of presence of A. phagocytophilum in wild boars in southern Belgium. PMID:24694049

    Toxoplasma gondii is a zoonotic protozoan parasite, infecting a wide range of warm-blooded animals. The Swedish wild boar population is expanding and increased hunting provides its meat to a growing group of consumers. We performed a spatio-temporal investigation of T. gondii seroprevalence in Swedish wild boars. An ELISA was set up and evaluated against a commercial direct agglutination test, using Bayesian latent class analysis. The ELISA sensitivity and specificity were estimated to 79% and 85%, respectively. Of 1327 serum samples, 50% were positive. Thirty-four per cent of young wild boars and 55% of adults were positive (P < 0·001). The total seroprevalence ranged from 72% in 2005 to 38% in 2011 (P < 0·001), suggesting a declining trend. The highest seroprevalence, 65%, was recorded in South Sweden. In other regions it varied from 29% in Stockholm to 46% in East Middle Sweden. PMID:25373497

    In this study, the left and right cranial cervical ganglia (ganglion cervicale craniale) of eight young (four male, four female) domestic pigs weighing around 70-80 kg were inspected macro anatomically. The cranial cervical ganglion (CCG) was found cranio-ventrally of the distal ganglion of the vagus nerve, medial of the jugular process extremity, ventral of the atlas, dorsal of the epiglottis base and medial of the common root (CR) established by the internal carotid and occipital arteries. The internal carotid nerve and jugular nerve ramified from the cranial part of CCG. The jugular nerve gave branches that merged with the vagus and glossopharyngeal nerves. Other nerve branches originating from the cranial part of the ganglion reached to the external carotid artery and CR. The internal carotid nerve varied among cadavers in number of branches (two to four). These branches did not travel along the side of the internal carotid artery. The central part of CCG gave thin nerve branches that reached to various anatomical structures including the first and second cervical nerves, wall of the pharynx, accessory nerve, hypoglossal nerve, vagus nerve, external carotid artery and CR. The caudal part of CCG gave nerve branches that merged with the vagus, cranial laryngeal nerves, and common carotid artery. The external carotid nerves, which were two or three in number, also originated from the caudal part of CCG. In conclusion, the nerves ramifying from CCG of the pig varied in number among cadavers. Compared with literature raised in other species, there are also differences in number of nerve branches and course pattern of these nerves. PMID:15929737

    The opioid buprenorphine has been shown to provide adequate postoperative analgesia in both companion and laboratory animals. However, its use is still hindered by the need for multiple parenteral injections to achieve continuous analgesia. The purpose of the current study was to conduct a pharmacokinetic analysis of 2 new long-acting formulations of buprenorphine—an injectable sustained-release buprenorphine (SRB) and a transdermal buprenorphine (TDB) patch—in healthy Göttingen minipigs by using liquid chromatography–electrospray ionization–tandem mass spectrometry. Administration of 0.18 mg/kg SC SRB and 30 ?g/h TDB achieved AUC0-Tlast of 221.6 ± 26.8 and 25.2 ± 3.9 ng × h/mL, respectively, compared with 9.7 ± 1.4 ng*h/mL for 0.02 mg/kg IV buprenorphine. By using a hypothesized therapeutic plasma buprenorphine concentration threshold of 0.1 ng/mL, therapeutic concentrations were achieved at the first study time point (5 to 30 min) and lasted an average of 8.0 ± 1.3 h for intravenous buprenorphine and 264.0 ± 32.2 h for SRB. TDB achieved therapeutic concentrations in 12 to 24 h after patch application, which lasted until the patch was removed at 72 h. The results of this study suggest that SRB and TDB are long-acting alternatives for pain management, and their use could decrease animal handling and stress, thereby simplifying pain management and improving welfare in laboratory swine.

    For the first time in the domestic pig, meiotic recombination along the 18 porcine autosomes was directly studied by immunolocalization of MLH1 protein. In total, 7,848 synaptonemal complexes from 436 spermatocytes were analyzed, and 13,969 recombination sites were mapped. Individual chromosomes for 113 of the 436 cells (representing 2,034 synaptonemal complexes) were identified by immunostaining and fluorescence in situ hybridization (FISH). The average total length of autosomal synaptonemal complexes per cell was 190.3 µm, with 32.0 recombination sites (crossovers), on average, per cell. The number of crossovers and the lengths of the autosomal synaptonemal complexes showed significant intra- (i.e. between cells) and inter-individual variations. The distributions of recombination sites within each chromosomal category were similar: crossovers in metacentric and submetacentric chromosomes were concentrated in the telomeric regions of the p- and q-arms, whereas two hotspots were located near the centromere and in the telomeric region of acrocentrics. Lack of MLH1 foci was mainly observed in the smaller chromosomes, particularly chromosome 18 (SSC18) and the sex chromosomes. All autosomes displayed positive interference, with a large variability between the chromosomes. PMID:24919066

    Forensic entomology uses pig carcasses to surrogate human decomposition and to investigate the entomofaunal colonization. Insects communicate with their environment through the use of chemical mediators, which in the case of necrophagous insects, may consist in the cadaveric volatile organic compounds (VOCs) released by the corpse under decomposition. Previous studies have focused on cadaveric VOCs released from human corpses. Nevertheless,

    Between 2007-2008 and 2010-2012, 870 organ samples were collected from wild boars in 16 Transylvanian counties. Anaplasma phagocytophilum DNA was identified using a nested PCR protocol that amplifies a fragment of the 16S rRNA gene. Prevalence was compared between sampling periods and counties using Fisher's exact test. In total, 39 (4·48%) samples tested positive, with significantly higher values recorded in the second period, caused by an increased infection rate in boars from Sibiu county. Positive cases tended to concentrate in the central part of the country. During the second sampling period, A. phagocytophilum was detected in two additional counties, suggesting a spatial spreading of the pathogen. The results confirm that Transylvanian wild boars are naturally infected with A. phagocytophilum, thus raising awareness concerning a potential zoonotic cycle. This is the first study to evaluate spatial and temporal variations of A. phagocytophilum distribution in wild boar populations from Transylvania. PMID:23611429

    This experiment investigated whether domestic pigs can remember the locations of food sites of different relative value, and how a restricted retrieval choice affects their foraging behaviour. Nine juvenile female pigs were trained to relocate two food sites out of a possible eight in a spatial memory task. The two baited sites contained different amounts of food and an obstacle

    We present a study of the observational properties of Galaxies in Groups and its AGN host galaxies. We analyze the characteristics of the emision from the host AGN galaxies, both in the optical region as in the radio fre- cuencies, and its relation with their environment. In order to make these studies, the information from AGN associated with galaxy clusters has been correlated to the FIRST radio survey. In this correlation we analyze the pa- rameters of these galaxies: luminosity, morphology, stellar mass, stellar age, etc. FULL TEXT IN SPANISH

    ``Black widow'' systems are located in a well determined region of the plane (where is the mass of the pulsar companion and is the orbital period of the system). An attempt has been made to understand which are the mechanisms that lead to companions of ``black widows'' to be located in this region; since standard binary evolution does not provide a satisfactory response. From our evolutionary calculations; we study the path performed in the plane by a binary system to reach the state of ``black widow''. We also discuss whether there is a connection between ``redbacks'' and ``black widows''. FULL TEXT IN SPANISH

    We describe the morphological, biological, and molecular characteristics of Cryptosporidium pig genotype II and propose the species name Cryptosporidium scrofarum n. sp. to reflect its prevalence in adult pigs worldwide. Oocysts of C. scrofarum are morphologically indistinguishable from C. parvum, measuring 4.81-5.96 ?m (mean=5.16)×4.23-5.29 ?m (mean=4.83) with a length to width ratio of 1.07±0.06 (n=400). Oocysts of C. scrofarum obtained from a naturally infected pig were infectious for 8-week-old pigs but not 4-week-old pigs. The prepatent period in 8-week-old Cryptosporidium-naive pigs was 4-6 days and the patent period was longer than 30 days. The infection intensity of C. scrofarum in pigs was generally low, in the range 250-4000 oocysts per gram of feces. Infected pigs showed no clinical signs of cryptosporidiosis and no pathology was detected. Cryptosporidium scrofarum was not infectious for adult SCID mice, adult BALB/c mice, Mongolian gerbils (Meriones unguiculatus), southern multimammate mice (Mastomys coucha), yellow-necked mice (Apodemus flavicollis), or guinea pigs (Cavia porcellus). Phylogenetic analyses based on small subunit rRNA, actin, and heat shock protein 70 gene sequences revealed that C. scrofarum is genetically distinct from all known Cryptosporidium species.

    Summary An overview of wild and feral swine behavior is presented. In spite of their success as a domesticated animal in the New World, swine are relative newcomers to the Americas. Feral swine, i.e., domesticated stocks which have reentered the wild habitat, apparently became established after early 'stocking' by Spanish explorers, and wild stocks stem from much more recent imports.

    Quantitative trait loci (QTL) affecting carcass and meat quality located on SSC2 were identified using variance component methods. A large number of traits involved in meat and carcass quality was detected in a commercial crossbred population: 1855 pigs sired by 17 boars from a synthetic line, which where homozygous (A/A) for IGF2. Using combined linkage and linkage disequilibrium mapping (LDLA), several QTL significantly affecting loin muscle mass, ham weight and ham muscles (outer ham and knuckle ham) and meat quality traits, such as Minolta-L* and -b*, ultimate pH and Japanese colour score were detected. These results agreed well with previous QTL-studies involving SSC2. Since our study is carried out on crossbreds, different QTL may be segregating in the parental lines. To address this question, we compared models with a single QTL-variance component with models allowing for separate sire and dam QTL-variance components. The same QTL were identified using a single QTL variance component model compared to a model allowing for separate variances with minor differences with respect to QTL location. However, the variance component method made it possible to detect QTL segregating in the paternal line (e.g. HAMB), the maternal lines (e.g. Ham) or in both (e.g. pHu). Combining association and linkage information among haplotypes improved slightly the significance of the QTL compared to an analysis using linkage information only. PMID:19284675

  2. Host predilection and transmissibility of vesicular stomatitis New Jersey virus strains in domestic cattle (Bos taurus) and swine (Sus scrofa)

    2012-01-01

    Background Epidemiologic data collected during epidemics in the western United States combined with limited experimental studies involving swine and cattle suggest that host predilection of epidemic vesicular stomatitis New Jersey virus (VSNJV) strains results in variations in clinical response, extent and duration of virus shedding and transmissibility following infection in different hosts. Laboratory challenge of livestock with heterologous VSNJV strains to investigate potential viral predilections for these hosts has not been thoroughly investigated. In separate trials, homologous VSNJV strains (NJ82COB and NJ82AZB), and heterologous strains (NJ06WYE and NJOSF [Ossabaw Island, sand fly]) were inoculated into cattle via infected black fly bite. NJ82AZB and NJ06WYE were similarly inoculated into swine. Results Clinical scores among viruses infecting cattle were significantly different and indicated that infection with a homologous virus resulted in more severe clinical presentation and greater extent and duration of viral shedding. No differences in clinical severity or extent and duration of viral shedding were detected in swine. Conclusions Differences in clinical presentation and extent and duration of viral shedding may have direct impacts on viral spread during epidemics. Viral transmission via animal-to-animal contact and insect vectored transmission are likely to occur at higher rates when affected animals are presenting severe clinical signs and shedding high concentrations of virus. More virulent viral strains resulting in more severe disease in livestock hosts are expected to spread more rapidly and greater distances during epidemics than those causing mild or inapparent signs.

    Flubendazole (FLU) is a widely administered benzimidazole anthelmintic indicated for the control of parasitic diseases in farm animals including pigs and pheasants. This study was designed to test the biotransformation of FLU in control animals and animals treated with FLU in recommended therapeutic doses. The activities of several pheasant and porcine hepatic and intestinal carbonyl reducing enzymes and their modulation by FLU were also studied. Twelve adult pheasant hens, approximately 1 year old, were divided into two groups and treated for 7 days with placebo or 6 mg of FLU/kg of body weight. Eight male hog weaners, approximately 3 month old, were divided into two groups and treated for 5 days with placebo or 1.57 mg of FLU/kg of body weight. Subcellular fractions, prepared from livers and small intestines of control and FLU treated animals, were incubated with FLU. In vitro formation of two main FLU metabolites, reduced FLU, and hydrolyzed FLU were analyzed using HPLC. While FLU was reduced significantly more intensively in FLU-treated pheasants than in control animals, no differences were observed in pigs. These results were confirmed by measuring the enzyme activities: carbonyl reducing enzyme activities were increased in pheasants treated by FLU, whereas FLU did not affect these enzymes in pigs.

    This study aimed to evaluate the role of wild boars and deer as reservoirs of foodborne bacteria. We investigated the prevalence and antimicrobial susceptibility of Campylobacter spp., Salmonella spp., Shiga toxin-producing Escherichia coli (STEC) O157 and O26, and Listeria monocytogenes isolated from wild boars and deer in Japan, from July through December 2010. Campylobacter spp. and Salmonella spp. were isolated from 43.8% (95% confidence interval [CI]: 35.0-52.6) and 7.4% (95% CI: 2.8-12.1) of rectal content samples of wild boars, respectively, but not from wild deer. The most common Campylobacter species was C. lanienae and C. hyointestinalis. The nine Salmonella serovars isolated were S. enterica subsp. enterica serovar Agona (three isolates), S. Narashino (two), S. Enteritidis (one), S. Havana (one), S. Infantis (one), and S. Thompson (one). Five (16%) and 6 (29%) isolates of C. lanienae and C. hyointestinalis, respectively, were resistant to enrofloxacin. STEC O157 and O26 and L. monocytogenes were isolated from 2.3% (95% CI: 0-5.0), 0.8% (95% CI: 0-2.3), and 6.1% (95% CI: 1.7-10.5) of the rectal content samples of wild deer, respectively, but not from wild boars. This first nationwide survey of the prevalence of foodborne bacteria in wild boars and wild deer in Japan suggests that consumption of meat from these animals is associated with the risk of causing infection with these bacteria in humans. Moreover, these animals are potential vehicles for distribution of antimicrobial-resistant bacteria into their habitat. The prevalence and antimicrobial susceptibility of such foodborne bacteria in these wild animals should be monitored periodically. PMID:24161070

    Due to the fact that morphology and perinatal growth of the piglet brain is similar to humans, use of the piglet as a translational animal model for neurodevelopmental studies is increasing. Magnetic resonance imaging (MRI) can be a powerful tool to study neurodevelopment in piglets, but many of the MRI resources have been produced for adult humans. Here, we present an average in vivo MRI-based atlas specific for the 4-week-old piglet. In addition, we have developed probabilistic tissue classification maps. These tools can be used with brain mapping software packages (e.g. SPM and FSL) to aid in voxel-based morphometry and image analysis techniques. The atlas enables efficient study of neurodevelopment in a highly tractable translational animal with brain growth and development similar to humans. PMID:25254955

    The merging of populations after an extended period of isolation and divergence is a common phenomenon, in natural settings as well as due to human interference. Individuals with such hybrid origins contain genomes that essentially form a mosaic of different histories and demographies. Pigs are an excellent model species to study hybridization because European and Asian wild boars diverged ~1.2 Mya, and pigs were domesticated independently in Europe and Asia. During the Industrial Revolution in England, pigs were imported from China to improve the local pigs. This study utilizes the latest genomics tools to identify the origin of haplotypes in European domesticated pigs that are descendant from Asian and European populations. Our results reveal fine-scale haplotype structure representing different ancient demographic events, as well as a mosaic composition of those distinct histories due to recently introgressed haplotypes in the pig genome. As a consequence, nucleotide diversity in the genome of European domesticated pigs is higher when at least one haplotype of Asian origin is present, and haplotype length correlates negatively with recombination frequency and nucleotide diversity. Another consequence is that the inference of past effective population size is influenced by the background of the haplotypes in an individual, but we demonstrate that by careful sorting based on the origin of haplotypes, both distinct demographic histories can be reconstructed. Future detailed mapping of the genomic distribution of variation will enable a targeted approach to increase genetic diversity of captive and wild populations, thus facilitating conservation efforts in the near future.

    Novel porcine parvoviruses showing the genetic characteristics of bocaviruses have recently been identified. The first such porcine bocavirus (PoBoV1), described as boca-like virus (PBo-likeV), was discovered in PMWS affected pigs in Sweden. Later, several other bocaviruses with divergent genomes were reported under various names in domestic pigs. This is the first report of the presence of bocaviruses in European wild boars. 842 wild boar samples originating from the Western region of Romania (Transylvania) were collected during the 2006/2007 and the 2010/2011 hunting seasons and tested for the presence of PoBoV1 by polymerase chain reaction and sequencing. The results showed 12.94% (109/842) overall positivity, with an increasing prevalence from the 2006/2007 (9.14%, 43/470) to the 2010/2011 (17.74%, 66/372) season (P < 0.01). Differences between the prevalence of the virus in 6-12-month-old-animal (77.06%, 84/109) and 12-36-month-old-animal (22.94%, 25/109) (P < 0.01) indicated that the infection occurred mainly in younger pigs. Comparative sequence analysis of partial VP1/2 genes from wild boars and those available in the GenBank showed only minor differences, indicating that PoBoV1 circulating within the wild boar populations and domestic pigs from different geographic regions were highly similar.

    Whole nerve, as well as single fiber, responses in the chorda tympani proper (CT) and glossopharyngeal (NG) nerves of 1- to 7-week-old pigs were recorded during taste stimulation. In the CT acids and in the NG bitter compounds gave the largest responses. Both nerves exhibited large responses to monosodium glutamate (MSG), MSG with guanosine 5'-monophosphate (GMP) and MSG with inositine 5'-monophosphate (IMP) as well as to glycine, xylitol, sucrose, fructose and glucose. Alitame, aspartame, betaine, neohesperedin dihydrochalcone (NHDHC), super-aspartame, saccharin and thaumatin elicited no or little response. Hierarchical cluster analysis of 49 CT fibers separated four major clusters. The M cluster, comprising 28.5% of all fibers, is characterized by strong responses to MSG, KCl, LiCl and NaCl. The responses to NaCl and LiCl were unaffected by amiloride. The H cluster (24.5%) includes units responding principally to acids. The Q cluster (18.5%) responds to quinine hydrochloride (QHCl), sucrose octaacetate (SOA) and salts with amiloride. The S cluster (28.5%) exhibits strong responses to xylitol, glycine and the carbohydrates as well as to MSG alone and to MSG with GMP or IMP. In 31 NG fibers, hierarchical cluster analysis revealed four clusters: the M cluster (10%), responding to MSG and MSG with GMP or IMP; the H cluster (13%), responding to acids; the Q cluster (29%), responding strongly to QHCl, SOA and tilmicosinR; and the S cluster (48%), responding best to xylitol, carbohydrates and glycine but also to the umami compounds. Multidimensional scaling analysis across fiber responses to all stimuli showed the best separation between compounds with different taste qualities when information from both nerves was utilized.

    Porcine babesiosis is a widespread yet overlooked disease causing economic losses in many regions of the world. To date, the etiological agent of porcine babesiosis has not been molecularly characterized. Here, we provide the first molecular characterization of a piroplasm detected in a symptomatic sow, phylogenetically closely related to the Ungulibabesids. Results pave the way for future molecular epidemiology studies. PMID:21490184

    Chromatin insulators affect interactions between promoters and enhancers/silencers and function as barriers for the spreading of repressive chromatin. Drosophila insulator protein dCTCF marks active promoters and boundaries of many histone H3K27 trimethylation domains associated with repressed chromatin. In particular, dCTCF binds to such boundaries between the parasegment-specific regulatory domains of the Bithorax complex. Here we demonstrate that the evolutionarily conserved protein ENY2 is recruited to the zinc-finger domain of dCTCF and is required for the barrier activity of dCTCF-dependent insulators in transgenic lines. Inactivation of ENY2 by RNAi in BG3 cells leads to the spreading of H3K27 trimethylation and Pc protein at several dCTCF boundaries. The results suggest that evolutionarily conserved ENY2 is responsible for barrier activity mediated by the dCTCF protein. PMID:25147918

    Threats of nuclear and other radiologic exposures have been increasing, but no countermeasure for acute radiation syndrome has been approved by regulatory authorities. Because of their similarity to humans in regard to physiology and anatomy, we are characterizing Gottingen minipigs as a model to aid the development of radiation countermeasures. Irradiated minipigs exhibit immunosuppression, severe thrombocytopenia, vascular leakage, and acute inflammation. These complications render serial acquisition of blood samples problematic. Vascular access ports (VAP) facilitate serial sampling, but their use often is complicated by infections and fibrin deposition. We demonstrate here the successful use of VAP for multiple blood samplings in irradiated minipigs. Device design and limited postoperative prophylactic antimicrobial therapy before irradiation were key to obtaining serial sampling, reducing swelling, and eliminating infection and skin necrosis at the implantation site. Modifications of previous protocols included the use of polydioxanone sutures instead of silk; eliminating chronic port access; single-use, sterile, antireflux prefilled syringes for flushing; strict aseptic weekly maintenance of the device, and acclimating animals to reduce stress. VAP remained functional in 19 of 20 irradiated animals for as long as 3 mo. The remaining VAP failed due to a small leak in the catheter, leading to clot formation. VAP-related sepsis occurred in 2 minipigs. Blood sampling did not cause detectable stress in nonanesthetized sham-irradiated animals, according to leukograms and clinical signs. PMID:21333166

    MicroRNAs (miRNAs) are a class of small, noncoding RNAs, which play a vital role in the regulation of gene expression by binding to the 3' untranslated region (3'UTR) of a target mRNA. Despite a significant improvement in the identification of miRNAs in a variety of species, the coverage of the porcine miRNAome is still scarce. To identify porcine miRNAs potentially regulating processes taking place in the liver, we applied next generation sequencing. As a result, we detected 206 distinct miRNAs, of which 68 represented potential novel miRNAs. Among these new miRNAs, there were miRNAs deriving from the opposite arm of a hairpin precursor of already known miRNAs. Moreover, we observed 3' and 5' length and sequence variants, probably constituting so called isomiRs, as well as differentially mapped precursor loci, alternative precursor sequences and clustering of miRNA encoding genes. On the basis of expression levels, reflected by the number of sequence reads, we identified the most abundant miRNAs followed by gene target prediction and pathway analysis. The enriched pathways were connected with cellular and metabolic processes, growth factors as well as enzymatic activity. The obtained results are the first ones to concern the porcine liver miRNAome. Consequently, they will increase the number of known porcine miRNAs and facilitate further research on gene regulation mechanisms as well as biological processes associated with the liver functioning in pigs.

    Trichinella surveillance in wildlife relies on muscle digestion of large samples which are logistically difficult to store and transport in remote and tropical regions as well as labour-intensive to process. Serological methods such as enzyme-linked immunosorbent assays (ELISAs) offer rapid, cost-effective alternatives for surveillance but should be paired with additional tests because of the high false-positive rates encountered in wildlife. We investigated the utility of ELISAs coupled with Western blot (WB) in providing evidence of Trichinella exposure or infection in wild boar. Serum samples were collected from 673 wild boar from a high- and low-risk region for Trichinella introduction within mainland Australia, which is considered Trichinella-free. Sera were examined using both an 'in-house' and a commercially available indirect-ELISA that used excretory-secretory (E/S) antigens. Cut-off values for positive results were determined using sera from the low-risk population. All wild boar from the high-risk region (352) and 139/321 (43.3%) of the wild boar from the low-risk region were tested by artificial digestion. Testing by Western blot using E/S antigens, and a Trichinella-specific real-time PCR was also carried out on all ELISA-positive samples. The two ELISAs correctly classified all positive controls as well as one naturally infected wild boar from Gabba Island in the Torres Strait. In both the high- and low-risk populations, the ELISA results showed substantial agreement (k-value=0.66) that increased to very good (k-value=0.82) when WB-positive only samples were compared. The results of testing sera collected from the Australian mainland showed the Trichinella seroprevalence was 3.5% (95% C.I. 0.0-8.0) and 2.3% (95% C.I. 0.0-5.6) using the in-house and commercial ELISA coupled with WB respectively. These estimates were significantly higher (P<0.05) than the artificial digestion estimate of 0.0% (95% C.I. 0.0-1.1). Real-time PCR testing of muscle from seropositive animals did not detect Trichinella DNA in any mainland animals, but did reveal the presence of a second larvae-positive wild boar on Gabba Island, supporting its utility as an alternative, highly sensitive method in muscle examination. The serology results suggest Australian wildlife may have been exposed to Trichinella parasites. However, because of the possibility of non-specific reactions with other parasitic infections, more work using well-defined cohorts of positive and negative samples is required. Even if the specificity of the ELISAs is proven to be low, their ability to correctly classify the small number of true positive sera in this study indicates utility in screening wild boar populations for reactive sera which can be followed up with additional testing.

    Study objective Hydroxocobalamin is a Food and Drug Administration–approved antidote for cyanide poisoning. Cobinamide is a potential antidote that contains 2 cyanide-binding sites. To our knowledge, no study has directly compared hydroxocobalamin with cobinamide in a severe, cyanide-toxic large-animal model. Our objective is to compare the time to return of spontaneous breathing in swine with acute cyanide-induced apnea treated with intravenous hydroxocobalamin, intravenous cobinamide, or saline solution (control). Methods Thirty-three swine (45 to 55 kg) were intubated, anesthetized, and instrumented (continuous mean arterial pressure and cardiac output monitoring). Anesthesia was adjusted to allow spontaneous breathing with FiO2 of 21% during the experiment. Cyanide was continuously infused intravenously until apnea occurred and lasted for 1 minute (time zero). Animals were then randomly assigned to receive intravenous hydroxocobalamin (65 mg/kg), cobinamide (12.5 mg/kg), or saline solution and monitored for 60 minutes. A sample size of 11 animals per group was selected according to obtaining a power of 80%, an ? of .05, and an SD of 0.17 in mean time to detect a 20% difference in time to spontaneous breathing. We assessed differences in time to death among groups, using Kaplan-Meier estimation methods, and compared serum lactate, blood pH, cardiac output, mean arterial pressure, respiratory rate, and minute ventilation time curves with repeated-measures ANOVA. Results Baseline weights and vital signs were similar among groups. The time to apnea and cyanide dose required to achieve apnea were similar. At time zero, mean cyanide blood and lactate concentrations and reduction in mean arterial pressure from baseline were similar. In the saline solution group, 2 of 11 animals survived compared with 10 of 11 in the hydroxocobalamin and cobinamide groups (P<.001 between the 2 treated groups and the saline solution group). Time to return of spontaneous breathing after antidote was similar between hydroxocobalamin and cobinamide (1 minute 48 seconds versus 1 minute 49 seconds, respectively). Blood cyanide concentrations became undetectable at the end of the study in both antidote-treated groups, and no statistically significant differences were detected between the 2 groups for mean arterial pressure, cardiac output, respiratory rate, lactate, or pH. Conclusion Both hydroxocobalamin and cobinamide rescued severely cyanide-poisoned swine from apnea in the absence of assisted ventilation. The dose of cobinamide was one fifth that of hydroxocobalamin. PMID:24746273

    The feral swine (FS) originated from the domestic pig and is present throughout the Brazilian wetland plain (the Pantanal). Aujeszky's disease (AD) was first serologically confirmed in the state of Mato Grosso do Sul (MS) in 2001; however, there was no viral confirmation. The aim of this study was to investigate antibodies against-SuHV-1 in the sera of feral swine in the studied areas, detect SuHV-1 through PCR and classify the viral genome. Among the 218 animals sampled, 186 were analyzed by ELISA, resulting in 88 (47.3%) reactive samples. In the serum neutralization test (SN), 57/179 (31.8%) samples presented antibodies against the AD virus (SuHV-1). By nested PCR, 104 DNA samples were extracted for analysis and confirmed with amplification of a fragment of glycoprotein B (gB) in five samples. The SuHV-1 was detected in 12 samples by using primers for glycoprotein E (gE) and viral genome was classified as Type I by ul44 partial sequencing. The amplification of SuHV-1 glycoprotein fragments in the fetuses of seropositive sows indicate that the vertical transmission contribute to maintain SuHV-1 in a free-living feral swine population. The origin of AD in the feral swine populations of the Pantanal is unknown, however, the determination of viral latency, the vertical transmission of the antigen by the amplification of SuHV-1 glycoprotein fragments in the fetuses of seropositive sows and genome typing contribute to the elucidation of the epidemiology of this disease in the wetlands of MS, Brazil.

    We report the isolation of Campylobacter species from the same population of feral swine that was investigated in San Benito County, California, during the 2006 spinach-related Escherichia coli O157:H7 outbreak. This is the first survey of Campylobacter in a free-ranging feral swine population in the United States. Campylobacter species were cultured from buccal and rectal-anal swabs, colonic faeces and tonsils using a combination of selective enrichment and antibiotic-free membrane filtration methods. Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF-MS, Bruker Daltonics, Inc., Billerica, MA, USA) was used to identify species followed by confirmatory multiplex PCR or 16S rRNA sequencing. Genetic relatedness of Campylobacter jejuni and Campylobacter coli strains was determined by multilocus sequence typing (MLST) and porA allele sequencing. Altogether, 12 (40%) of 30 feral swine gastrointestinal and oral cavity specimens were positive, and six species were isolated: Campylobacter coli, Campylobacter fetus, Campylobacter hyointestinalsis, Campylobacter jejuni, Campylobacter lanienae and Campylobacter sputorum. Campylobacter jejuni subtypes were closely related to MLST sequence type 21 (ST-21) and had identical porA sequences. Campylobacter coli subtypes were unrelated to isolates in the pubMLST/porA database. This feral swine population lived in close association with a 'grassfed' beef cattle herd adjacent to spinach and other leafy green row crop fields. The findings underscore the importance of protecting raw vegetable crops from faecal contamination by wild or feral animals. The study also illustrates a potential risk of Campylobacter exposure for hunters during handling and processing of wild swine meat. PMID:22405465

    The faunal assemblage from the 9th-8th millennium BP site at Sha'ar Hagolan, Israel, is used to study human interaction with wild suids and cattle in a time period just before the appearance of domesticated animals of these species in the Jordan Valley. Our results, based on demographic and osteometric data, indicate that full domestication of both cattle and suids occurred at the site during the 8th millennium. Importantly, domestication was preceded in both taxa by demographic and metric population parameters indicating severe overhunting. The possible role of overhunting in shaping the characteristics of domesticated animals and the social infrastructure to ownership of herds is then explored. PMID:23405240

    The Bosniak classification for renal cysts was developed in the late 1980s in an attempt to standardize the description and management of complex cystic renal lesions. Alterations were made to such a classification in the 1990s and, the last one, in 2005. Currently, five categories of cystic renal lesions are defined - namely, I, II, II-F, III and IV –, according to their degree of complexity and likelihood of malignancy. Despite being initially described for computed tomography, this classification has been also utilized with some advantages also for magnetic resonance imaging. The present article reviews the different phases of this classification, its diagnostic efficacy and the most controversial features of its use. PMID:25741118

    Radiotelemetry was used to evaluate diet-related elevation of blood pressure in adult Yucatan miniature swine. Systolic arterial blood pressure (SAP), diastolic atrial blood pressure (DAP), heart rate, and locomotor activity were assessed in 9- or 11-mo-old Yucatan miniature pigs fed a standard diet or a North American-type diet high in salt, fat, and sugar (HSFS). Compared with pigs fed standard diet, pigs fed HSFS diet showed markedly elevated SAP (132 ± 3 compared with 156 ± 6 mm Hg), whereas DAP was unchanged (92 ± 2 compared with 99 ± 5 mm Hg). In addition, all pigs were modestly sensitive to short-term changes in dietary salt, as indicated by a 6% to 7% response in blood pressure parameters. According to these data, the increase in SAP for pigs on the HSFS diet was too large to be explained by the NaCl content of the diet alone. We found no evidence of endothelial dysfunction, and the relaxation responses of isolated coronary arteries actually were enhanced in the HSFS group. In conclusion, in a Yucatan miniature pigs model chronically fed a HSFS diet, DAP did not increase, but SAP and pulse pressure appeared to be affected by high dietary levels of fat or sugar (or both).

    During the last 12 years, an increasing frequency in condemnation of hunted red deer and wild boar carcasses due to the presence of tubercle-like lesions has been observed in Extremadura (Western Spain). Before 1993, tuberculosis was a very rare finding in hunted animals. The current tuberculosis regional prevalence in cattle approaches 0.4% after years of expensive test and slaughter campaigns. It is imperative to investigate the epidemiology of Mycobacterium bovis infection in red deer and wild boar in order to keep a good health status and to maintain the effectiveness of domestic species TB eradication programs. The present paper evaluates the problem in Sierra de San Pedro, estimating the prevalence of TB in wild boar and red deer, the main wild artiodactyls in the area, and domestic cattle since 1992-2004, by the use of a low-cost surveillance method based on detailed pathological inspection of hunted animal carcasses. Microbiology and molecular epidemiology studies on several M. bovis isolates from domestic and wild animals helped to define the interspecies contacts. These findings, as well as recent history of game estates management and descriptive epidemiology field work, throw light on the rise and maintenance of these epizootics. PMID:16297475

    Current literature suggests that the effects of midazolam, a water-soluble benzodiazepine, on blood pressure in swine are minimal. The hypothesis of the study reported here was that a light sedative dose would induce a de- crease in blood pressure in this species.

    The diversity of olfactory binding proteins (OBPs) is a key point to understand their role in molecular olfaction. Since only few different sequences were characterized in each mammalian species, they have been considered as passive carriers of odors and pheromones. We have explored the soluble proteome of pig nasal mucus, taking benefit of the powerful tools of proteomics. Combining two-dimensional electrophoresis, mass spectrometry, and western-blot with specific antibodies, our analyses revealed for the first time that the pig nasal mucus is mainly composed of secreted OBP isoforms, some of them being potentially modified by O-GlcNAcylation. An ortholog gene of the glycosyltransferase responsible of the O-GlcNAc linking on extracellular proteins in Drosophila and Mouse (EOGT) was amplified from tissues of pigs of different ages and sex. The sequence was used in a phylogenetic analysis, which evidenced conservation of EOGT in insect and mammalian models studied in molecular olfaction. Extracellular O-GlcNAcylation of secreted OBPs could finely modulate their binding specificities to odors and pheromones. This constitutes a new mechanism for extracellular signaling by OBPs, suggesting that they act as the first step of odor discrimination. PMID:25538681

    This study aimed to analyze perceptions of conflict between workers and managers in primary healthcare units and to present a typology of conflicts on the job. This was a comprehensive interpretive case study with a critical hermeneutic approach. Data collection techniques included: focus group with managers, workplace observation, and worker interviews, conducted from April to November 2011. The results were triangulated and indicated the coexistence of distinct concepts of conflict, typified in six modalities: lack of collaboration at work; disrespect resulting from asymmetrical relations between workers; problematic employee behavior; personal problems; asymmetry with other management levels; and inadequate work infrastructure. The relevance of (non)mutual recognition, as proposed by Axel Honneth, stood out in the interpretation of the causes and practical implications of these conflicts. PMID:25166942

    The Göttingen minipig is an excellent model for studying effects of dietary high-fat intake on obesity. In this study, we analyzed the expression level of microRNA-122 (miRNA-122) and its target mRNA, CAT1, in intact young male minipigs fed either high-cholesterol or standard diet for 11 wk. MiRNA-122 and CAT1 are known to be important regulators of lipid metabolism. The weight of the young minipigs was monitored once a week during the feeding period; measurements of total cholesterol, triglycerides, high-density lipoproteins, and low-density lipoproteins were recorded at 4 time points (8, 14, 16, and 19 wk of age) in fasting animals during the feeding scheme. Body weight, total cholesterol, and high-density lipoproteins were higher in pigs fed the high-cholesterol compared with the standard diet. In contrast, the level of triglycerides was lower in pigs on the high-cholesterol diet than those receiving the standard diet. Pigs fed high-cholesterol also had lower miRNA-122 levels than did those fed the standard diet. These results suggest that in our minipigs, the increase in weight and cholesterol levels resulting from subchronic (11 wk) feeding of a high-cholesterol diet is correlated with a decrease in the expression of miRNA-122, confirming the implication of this microRNA in obesity. Gene expression levels of CAT1 did not differ between groups. PMID:20412689

  20. Stage-specific differential gene expression profiling and functional network analysis during morphogenesis of diphyodont dentition in miniature pigs, Sus Scrofa

    PubMed Central

    2014-01-01

    Background Our current knowledge of tooth development derives mainly from studies in mice, which have only one set of non-replaced teeth, compared with the diphyodont dentition in humans. The miniature pig is also diphyodont, making it a valuable alternative model for understanding human tooth development and replacement. However, little is known about gene expression and function during swine odontogenesis. The goal of this study is to undertake the survey of differential gene expression profiling and functional network analysis during morphogenesis of diphyodont dentition in miniature pigs. The identification of genes related to diphyodont development should lead to a better understanding of morphogenetic patterns and the mechanisms of diphyodont replacement in large animal models and humans. Results The temporal gene expression profiles during early diphyodont development in miniature pigs were detected with the Affymetrix Porcine GeneChip. The gene expression data were further evaluated by ANOVA as well as pathway and STC analyses. A total of 2,053 genes were detected with differential expression. Several signal pathways and 151 genes were then identified through the construction of pathway and signal networks. Conclusions The gene expression profiles indicated that spatio-temporal down-regulation patterns of gene expression were predominant; while, both dynamic activation and inhibition of pathways occurred during the morphogenesis of diphyodont dentition. Our study offers a mechanistic framework for understanding dynamic gene regulation of early diphyodont development and provides a molecular basis for studying teeth development, replacement, and regeneration in miniature pigs.

    Synchrotron X-ray diffraction (XRD) and X-ray fluorescent (XRF) measurement techniques have been used for non-destructive characterization of surface oxide films on Type 316L austenitic stainless steels that were exposed to simulated primary water environments of pressurized water reactors (PWR) and boiling water reactors (BWR). The layer structures of the surface spinel oxides were revealed ex situ after oxidation by measurements made as a function of depth. The layer structure of spinel oxides formed in simulated PWR primary water should normally be different from that formed in simulated BWR water. After oxidation in the simulated BWR environment, the spinel oxide was observed to contain NiFe2O4 at shallow depths, and FeCr2O4 and Fe3O4 at deeper depths. By contrast, after oxidation in the simulated PWR primary water environment, a Fe3O4 type spinel was observed near the surface and FeCr2O4 type spinel near the interface with the metal substrate. Furthermore, by in situ measurements during oxidation in the simulated BWR environment, it was also demonstrated that the ratio between spinel and hematite Fe2O3 can be changed depending on the water condition such as BWR normal water chemistry or BWR hydrogen water chemistry.

    El hospital psiquiátrico se ha constituido como un lugar donde se posibilita legitimar la exclusión y la radicalidad de ese otro “que no es igual”, como es el caso del sujeto que atenta contra su propia vida. En consecuencia, el intento de suicidio desde el pensamiento foucaultiano, es una resistencia que desmantela la estructura de dominación a través de un acto de poder, el cual se ejerce sobre el propio cuerpo. Así, la intención de este texto es mostrar que la relación Otro-otro es un lugar en la estructura subjetiva, que se deposita en la institución psiquiátrica, la cual representa el poder, la ley, y es aquello a lo que se le quiere agredir, resistir, abatir con un intento de suicidio. Para demostrar como se materializan estos hechos, se exponen los testimonios de tres adolescentes atendidas en un hospital psiquiátrico por intentos suicidas, en los cuales se señalan los diferentes significados que le atribuyen a la institución psiquiátrica en tanto que representa un Otro en sus actos autoinfligidos.

    2007-12-01

    The research presented in this article is about the way science teachers from Elementary School think about astronomical elements. Its methodology is based on semi-structured interviews, which were video recorded. The research is centered in a three-dimensional perspective of astronomical Earth, the Sun, the Moon, the planets and the stars, and also the conceptions about sky and Universe. The esults indicate a Universe that contains: Sun, stars, planets and Moon; where the Solar System is a little part of the whole. Sometimes they think that the Solar System is the Universe. The objects are in the sky or in the Universe, which, for many of them, is only the space above the Earth. The flat shape of astronomical objects and the spatial structure of the Universe are striking features. Many of them think that Sun and stars are different: the Sun is a hot object and the stars are cold ones. These results worry us and they certainly indicate how urgent it is to plan Professional Development in Astronomy for teachers, after all the PCN's emphasize that this subject is important to be taught. El objeto de investigación de este artículo es la manera de pensar sobre los elementos de la Astronomía de los profesores de Ciencias en la enseñanza fundamental. La metodología consiste en entrevistas semi-estructuradas, filmadas en video y centradas en la tridimensionalidad de los elementos astronómicos, para posibilitar un mapeamiento de las concepciones sobre las formas y dimensiones de la Tierra, del Sol, de la Luna, de los planetas y de las estrellas, como también de la concepción de cielo y de Universo en su totalidad. Los resultados indican un Universo conteniendo: Sol, estrellas, planetas y Luna, donde el Sistema Solar se ubica como parte. Algunas veces, el Universo es concebido como el propio Sistema Solar. Los objetos están en el cielo o en el Universo, que, para muchos, se restringe al espacio que está arriba de la Tierra. La forma plana de los objetos astronómicos y la estructura espacial del montaje del Universo son características fundamentales. Muchos indican Sol y estrellas como cosas distintas: el Sol es un objeto caliente y las estrellas son frías. Esos resultados nos preocupan y ciertamente señalan una urgencia de programas de formación continuada para profesores en el contenido de astronomía, pues los PCN's (Parámetros Curriculares Nacionales) recomiendan con énfasis la enseñanza de este contenido.

    Sucrose (Suc) synthase (Sus) is the major enzyme of Suc breakdown for cellulose biosynthesis in cotton (Gossypium hirsutum) fiber, an important source of fiber for the textile industry. This study examines the tissue-specific expression, relative abundance, and temporal expression of various Sus transcripts and proteins present in cotton. A novel isoform of Sus (SusC) is identified that is expressed at high levels during secondary cell wall synthesis in fiber and is present in the cell wall fraction. The phylogenetic relationships of the deduced amino acid sequences indicate two ancestral groups of Sus proteins predating the divergence of monocots and dicots and that SusC sequences form a distinct branch in the phylogeny within the dicot-specific clade. The subcellular location of the Sus isoforms is determined, and it is proposed that cell wall-localized SusC may provide UDP-glucose for cellulose and callose synthesis from extracellular sugars.

    In all plant species studied to date, sucrose synthase occurs as multiple isoforms. The specific functions of the different isoforms are for the most part not clear. Six isoforms of sucrose synthase have been identified in the model legume Lotus japonicus, the same number as in Arabidopsis (Arabidopsis thaliana) and rice (Oryza sativa). The genes encoding these isoforms are differentially expressed in all plant organs examined, although one, LjSUS4, is only expressed in flowers. LjSUS1 is the most highly expressed in all plant organs tested, except root nodules, where LjSUS3 accounts for more than 60% of the total SUS transcripts. One gene, LjSUS2, produces two transcripts due to alternative splicing, a feature not observed in other species to date. We have isolated plants carrying ethyl methanesulfonate-induced mutations in several SUS genes by targeting-induced local lesions in genomes reverse genetics and examined the effect of null alleles of two genes, LjSUS1 and LjSUS3, on nodule function. No differences were observed between the mutants and wild-type plants under glasshouse conditions, but there was evidence for a nitrogen-starvation phenotype in the sus3-1 mutant and severe impairment of growth in the sus1-1/sus3-1 double mutant under specific environmental conditions. Nodules of sus3-1 mutant plants retained a capacity for nitrogen fixation under all conditions. Thus, nitrogen fixation can occur in L. japonicus nodules even in the absence of LjSUS3 (the major nodule-induced isoform of SUS), so LjSUS1 must also contribute to the maintenance of nitrogen assimilation.

  12. ‘Everybody knows’, but the rest of the world: the case of a caterpillar-borne reproductive loss syndrome in dromedary camels observed by Sahrawi pastoralists of Western Sahara

    PubMed Central

    2013-01-01

    Background The traditional knowledge of local communities throughout the world is a valuable source of novel ideas and information to science. In this study, the ethnoveterinary knowledge of Sahrawi pastoralists of Western Sahara has been used in order to put forward a scientific hypothesis regarding the competitive interactions between camels and caterpillars in the Sahara ecosystem. Methods Between 2005 and 2009, 44 semi-structured interviews were conducted with Sahrawi pastoralists in the territories administered by the Sahrawi Arab Democratic Republic, Western Sahara, using a snow-ball sampling design. Results Sahrawi pastoralists reported the existence of a caterpillar-borne reproductive loss syndrome, known locally as duda, affecting their camels. On the basis of Sahrawi knowledge about duda and of a thorough literature review, we built the hypothesis that: 1) caterpillars of the family Lasiocampidae (genera Lasiocampa, Psilogaster, or Streblote) have sudden and rare outbreaks on Acacia treetops in the Western Sahara ecosystem after heavy rainfall; 2) during these outbreaks, camels ingest the caterpillars while browsing; 3) as a consequence of this ingestion, pregnant camels have sudden abortions or give birth to weaklings. This hypothesis was supported by inductive reasoning built on circumstantiated evidence and analogical reasoning with similar syndromes reported in mares in the United States and Australia. Conclusions The possible existence of a caterpillar-borne reproductive loss syndrome among camels has been reported for the first time, suggesting that such syndromes might be more widespread than what is currently known. Further research is warranted to validate the reported hypothesis. Finally, the importance of studying folk livestock diseases is reinforced in light of its usefulness in revealing as yet unknown biological phenomena that would deserve further investigation. Resumen ‘Todos lo saben’, menos el resto del mundo: el caso de un síndrome de pérdida reproductiva en dromedarios transmitido por orugas y observado por pastores nómadas saharauis del Sáhara Occidental. Antecedentes Los conocimientos tradicionales de las comunidades locales de todo el mundo son una valiosa fuente de nuevas ideas e información para la ciencia. En este estudio, se utilizaron los conocimientos de etnoveterinaria de pastores saharauis del Sáhara Occidental con el fin de proponer una hipótesis científica sobre las interacciones competitivas entre los camellos y las orugas en el ecosistema del Sáhara. Métodos Entre los años 2005 y 2009, se realizaron 44 entrevistas semi-estructuradas a los pastores saharauis en los territorios administrados por la República Árabe Saharaui Democrática, Sáhara Occidental, mediante un diseño de muestreo por bola de nieve. Resultados Los pastores nómadas saharauis describieron un síndrome reproductivo transmitido por orugas, llamado duda, entre sus camellas. Sobre la base de los conocimientos saharauis sobre el duda y una revisión literaria exhaustiva, se propuso la siguiente hipótesis: 1) brotes esporádico de orugas de la familia Lasiocampidae (géneros Lasiocampa, Psilogaster o Streblote) en árboles de Acacia se pueden presentar después de fuertes lluvias en el ecosistema del Sáhara Occidental; 2) durante estos brotes, los camellos ingieren las orugas durante el pastoreo; 3) como consecuencia de esta ingestión, se producen abortos repentinos o partos de crías debilitadas. Apoyamos esta hipótesis mediante razonamiento inductivo basado en evidencia circunstancial y razonamiento analógico con síndromes similares en yeguas de los Estados Unidos y Australia. Conclusiones Este es el primer reporte de la posible existencia de un síndrome de pérdida reproductiva en camellos, transmitido por orugas. Se insinúa que estos síndromes son más comunes que lo que actualmente se conoce. Se sugieren investigaciones adicionales p

  13. Renewal-Theoretical Dynamic Spectrum Access in Cognitive Radio Networks with Unknown Primary Behavior

    E-print Network

    Jiang, Chunxiao; Liu, K J Ray; Ren, Yong

    2011-01-01

    Dynamic spectrum access in cognitive radio networks can greatly improve the spectrum utilization efficiency. Nevertheless, interference may be introduced to the Primary User (PU) when the Secondary Users (SUs) dynamically utilize the PU's licensed channels. If the SUs can be synchronous with the PU's time slots, the interference is mainly due to their imperfect spectrum sensing of the primary channel. However, if the SUs have no knowledge about the PU's exact communication mechanism, additional interference may occur. In this paper, we propose a dynamic spectrum access protocol for the SUs confronting with unknown primary behavior and study the interference caused by their dynamic access. Through analyzing the SUs' dynamic behavior in the primary channel which is modeled as an ON-OFF process, we prove that the SUs' communication behavior is a renewal process. Based on the Renewal Theory, we quantify the interference caused by the SUs and derive the corresponding close-form expressions. With the interference a...

  14. Sink- and vascular-associated sucrose synthase functions are encoded by different gene classes in potato.

    PubMed Central

    Fu, H; Park, W D

    1995-01-01

    Two differentially regulated classes of sucrose synthase genes, Sus3 and Sus4, were identified in potato. They cannot be classified as Sus1 and Sus2 types based on sequence homology and appear to have evolved after the divergence of the major families of dicotyledonous plants but before the divergence of tomato and potato. The potato sucrose synthase clones Sus3-65 and Sus4-16 share an 87% nucleotide identity in the coding regions, and both are interrupted by 13 introns, including a long leader intron. Potato Sus3 genes are expressed at the highest levels in stems and roots and appear to provide the vascular function of sucrose synthase. In contrast, Sus4 genes are expressed primarily in the storage and vascular tissue of tubers and appear to facilitate sink function. The genes are differentially regulated in root tips, with Sus3 expressed at high levels in the cell division zone and Sus4 expressed at high levels in the meristem and cap. PMID:8589622

    Many kinds of stainless steel have been used in the engineering field. So it is necessary to investigate the effect of SUS chemical compositions on the brazing ability of filler metal. In this study, SUS315J containing Cr, Ni, Si, Cu, and Mo was employed as a base metal. Excellent spreading ability of the molten nickel-based brazing filler on SUS315J was obtained as compared with that on SUS316. Copper and silicon influenced the significant spreading ability of the filler.

    Austenitic stainless steel transforms from austenitic crystal structure to martensitic crystal structure after applying strain or stress. Because martensitic crystal structures have magnetization, strain evaluation and fatigue evaluation can be performed by measuring magnetic properties. This paper describes the measurement of leakage magnetic flux density of remanent magnetization for the strain evaluation and the fatigue evaluation by a typical Hall element sensor for SUS 304 and SUS 304L and by a high-sensitivity thin-film flux-gate magnetic sensor for SUS 316 and SUS 316L.

El objetivo del presente artículo es dar a conocer el estado del arte en relación a la epidemiologia, consecuencias y factores de riesgo para VP entre mujeres Hispanas, discutiendo las implicaciones para la investigación y la práctica. Investigaciones han demostrado una fuerte asociación del status socioeconómico, abuso de droga y el alcohol, la salud mental, aculturación, inmigración, comportamientos sexuales riesgosos e historia de abuso con la violencia entre parejas. Sin embargo, más estudios se deben llevar a cabo para identificar otros factores de riesgos y de protección a poblaciones hispanas no clínicas. Mientras que el conocimiento sobre la etiología de la VP entre mujeres Hispanas se expanda, enfermeras y otros profesionales de la salud deben desarrollar, implementar y evaluar estrategias culturalmente adecuadas para la prevención primaria y secundaria de la violencia entre pareja.

    Cotton (Gossypium hirsutum L.) seed develops single- celled long fibres (lint) from the seed-coat epidermis at anthesis. Previous studies have shown that the initi- ation and rapid elongation of these fibres requires the expression of sucrose synthase (Sus) and, potentially, a transient closure of plasmodesmata. This study extends the previous work to examine the patterns of Sus expression and plasmodesmata

    2015-03-01

    Sulfonylurea herbicides (SUs) were detected in natural waters and could be potentially exposed to human beings via portable use. Thus, the removal of five representative SUs in simulated water treatment processes including coagulation, activated carbon adsorption, and chlorination disinfection was systematically investigated. Results showed that coagulation had little effect on the removal of the herbicides with the average removal less than 10 %. Powder-activated carbon adsorption was apparently more effective with removal rates of 50?~?70 %. SUs were also partially removed in chlorination process. A complete removal was achieved when the three treatments were performed in series. However, it was found that parts of the SUs were transformed into certain stable products with triazine/pyrimidine structures which might be of potential health risks in chlorination process. Thus, current drinking water treatment processes are not likely to provide sufficient protection for human population from exposure to SUs. PMID:25269843

  1. Robust Distributed Power Control in Cognitive Radio Networks

    2011-01-01

    We propose a robust distributed uplink power allocation algorithm for underlay cognitive radio networks (CRNs) with a view to maximizing the total utility of secondary users (SUs) when channel gains from SUs to primary base stations, and interference caused by primary users (PUs) to the SUs' base station are uncertain. In doing so, we utilize the worst-case robust optimization to keep the interference caused by SUs to each primary base station below a given threshold, and satisfy the SUs' quality of service for all realizations of uncertainty. We model each uncertain parameter by a bounded distance between its estimated and exact values, and formulate the robust power allocation problem via protection values for constraints. We demonstrate that the convexity of our problem is preserved, and in some cases converts into a geometric programming problem, which we solve via a distributed algorithm by using Lagrange dual decomposition. To reduce the cost of robustness, defined as the reduction in the total utility ...

    SusB, an 84-kDa ?-glucoside hydrolase involved in the starch utilization system (sus) of Bacteroides thetaiotaomicron, belongs to glycoside hydrolase (GH) family 97. We have determined the enzymatic characteristics and the crystal structures in free and acarbose-bound form at 1.6Å resolution. SusB hydrolyzes the ?-glucosidic linkage, with inversion of anomeric configuration liberating the ?-anomer of glucose as the reaction product. The substrate specificity of SusB, hydrolyzing not only ?-1,4-glucosidic linkages but also ?-1,6-, ?-1,3-, and ?-1,2-glucosidic linkages, is clearly different from other well known glucoamylases belonging to GH15. The structure of SusB was solved by the single-wavelength anomalous diffraction method with sulfur atoms as anomalous scatterers using an in-house x-ray source. SusB includes three domains as follows: the N-terminal, catalytic, and C-terminal domains. The structure of the SusB-acarbose complex shows a constellation of carboxyl groups at the catalytic center; Glu532 is positioned to provide protonic assistance to leaving group departure, with Glu439 and Glu508 both positioned to provide base-catalyzed assistance for inverting nucleophilic attack by water. A structural comparison with other glycoside hydrolases revealed significant similarity between the catalytic domain of SusB and those of ?-retaining glycoside hydrolases belonging to GH27, -36, and -31 despite the differences in catalytic mechanism. SusB and the other retaining enzymes appear to have diverged from a common ancestor and individually acquired the functional carboxyl groups during the process of evolution. Furthermore, sequence comparison of the active site based on the structure of SusB indicated that GH97 included both retaining and inverting enzymes. PMID:18981178

  3. A reassessment of the role of sucrose synthase in the hypoxic sucrose-ethanol transition in Arabidopsis.

    Plants under low-oxygen availability adapt their metabolism to compensate for the lower ATP production that arises from the limited respiratory activity in mitochondria. Anaerobic glycolysis requires continuous fuelling of carbon units, also provided from sucrose. The anaerobic catabolism of sucrose is thought to require the activity of sucrose synthase, being this enzymatic reaction more energetically favourable than that of invertase. The role of sucrose synthases (SUS) for aerobic sucrose catabolism in Arabidopsis has been recently questioned since SUS mutants fail to show altered phenotype or metabolic profile. In the present paper, we analysed the role of SUS1 and SUS4, both induced by low oxygen, in plant survival and ethanol production. The results showed that mutants lacking both SUS were as tolerant to low oxygen as the wild type in most of the experimental conditions tested. Only under conditions of limiting sugar availability the requirement of SUS1 and SUS4 for ethanol production was evident, although partly compensated by invertase activities, as revealed by the use of a double mutant lacking the two major cytosolic invertases. We conclude that, contrary to general belief, the sucrose synthase pathway is not the preferential route for sucrose metabolism under hypoxia. PMID:24810896

    Pinheiro Filho, Francisco Percival; Sarti, Flávia Mori

    2012-11-01

    The principles and guidelines of the Brazilian Unified Health System (SUS) impose a healthcare service structure based on public policy networks which, combined with the financing model adopted, leads to market failings. This imposes barriers to the management of the public health system and the enactment of SUS objectives. The institutional characteristics and the heterogeneity of players, allied to the existence of different healthcare approaches, generate analytical complexity in the study of the global dynamics of the SUS network. There are limitations in the use of quantitative methods based on static analysis of retrospective SUS data. Thus, an approach taking SUS as a complex system using innovative quantitative methodology based on computational simulation is proposed. This paper sought to analyze challenges and possibilities of the combined application of cellular automata modeling and agent-based modeling for simulation of the evolution of the SUS healthcare service network. This approach should permit better understanding of the organization, heterogeneity and structural dynamics of the SUS service network and a minimization of the effects of market failings on the Brazilian health system.

  5. Multifunctional Nutrient-Binding Proteins Adapt Human Symbiotic Bacteria for Glycan Competition in the Gut by Separately Promoting Enhanced Sensing and Catalysis

    ABSTRACT To compete for the dynamic stream of nutrients flowing into their ecosystem, colonic bacteria must respond rapidly to new resources and then catabolize them efficiently once they are detected. The Bacteroides thetaiotaomicron starch utilization system (Sus) is a model for nutrient acquisition by symbiotic gut bacteria, which harbor thousands of related Sus-like systems. Structural investigation of the four Sus outer membrane proteins (SusD, -E, -F, and -G) revealed that they contain a total of eight starch-binding sites that we demonstrated, using genetic and biochemical approaches, to play distinct roles in starch metabolism in vitro and in vivo in gnotobiotic mice. SusD, whose homologs are abundant in the human microbiome, is critical for the initial sensing of available starch, allowing sus transcriptional activation at much lower concentrations than without this function. In contrast, seven additional binding sites across SusE, -F, and -G are dispensable for sus activation. However, they optimize the rate of growth on starch in a manner dependent on the expression of the bacterial polysaccharide capsule, suggesting that they have evolved to offset the diffusion barrier created by this structure. These findings demonstrate how proteins with similar biochemical behavior can serve orthogonal functions during different stages of cellular adaptation to nutrients. Finally, we demonstrated in gnotobiotic mice fed a starch-rich diet that the Sus binding sites confer a competitive advantage to B. thetaiotaomicron in vivo in a manner that is dependent on other colonizing microbes. This study reveals how numerically dominant families of carbohydrate-binding proteins in the human microbiome fulfill separate and sometimes cooperative roles to optimize gut commensal bacteria for nutrient acquisition.

    1992-01-01

    The effect of simulated microgravity on the insulin- and exercise-stimulated glucose uptake and metabolism in the hindlimb muscles of rats was investigated using three groups of rats suspended at 45 head-down tilt (SUS) for 14 days: (1) cage control, (2) exercising (treadmill running) control, and (3) rats subjected to suspension followed by exercise (SUS-E). It was found that the suspension of rats with hindlimbs non-weight bearing led to enhanced muscle responses to insulin and exercise, when these stimuli were applied separately. However, the insulin affect appeared to be impaired after exercise for the SUS-E rats, especially for the soleus muscle.

  12. Distributed Multiuser Sequential Channel Sensing Schemes in Multichannel Cognitive Radio Networks

    E-print Network

    Shokri-Ghadikolaei, Hossein; Nasiri-Kenari, Masoumeh

    2012-01-01

    Effective spectrum sensing strategies enable cognitive radios (CRs) to identify and opportunistically transmit on under-utilized spectral resources. In this paper, sequential channel sensing problems for single and multiple secondary users (SUs) cases are effectively modeled through finite state Markovian processes. More specifically, a model for single user case is introduced and validated through analytical analysis. In order to address multiple SUs, this model is extended to modified p-persistent access (MPPA) and its generalized version. While the introduced analytical framework facilitates the process of performance evaluation, these algorithms experience a high level of collision among the SUs. To mitigate this problem appropriately, p-persistent random access (PPRA) scheme is proposed, which offers higher average throughput for SUs by statistically distributing their loads among all channels. The structure and performance of the proposed schemes are discussed in detail, and a set of illustrative numeri...

  13. Attack Prevention for Collaborative Spectrum Sensing in Cognitive Radio Networks

    Duan, Lingjie; Huang, Jianwei; Shin, Kang G

    2011-01-01

    Collaborative spectrum sensing can significantly improve the detection performance of secondary unlicensed users (SUs). However, the performance of collaborative sensing is vulnerable to sensing data falsification attacks, where malicious SUs (attackers) submit manipulated sensing reports to mislead the fusion center's decision on spectrum occupancy. Moreover, attackers may not follow the fusion center's decision regarding their spectrum access. This paper considers a challenging attack scenario where multiple rational attackers overhear all honest SUs' sensing reports and cooperatively maximize attackers' aggregate spectrum utilization. We show that, without attack-prevention mechanisms, honest SUs are unable to transmit over the licensed spectrum, and they may further be penalized by the primary user for collisions due to attackers' aggressive transmissions. To prevent such attacks, we propose two novel attack-prevention mechanisms with direct and indirect punishments. The key idea is to identify collisions...

    2014-06-01

    This study analyzes the supply and use of computed tomography scanners (CT) in the Brazilian Unified National Health System (SUS) according to State and administrative levels in the year 2009. Secondary data were used to estimate the installed CT capacity in public healthcare facilities and in private services outsourced by the SUS and calculated the rate of utilization. Average national CT utilization was less than 10%. The public sector showed lower CT use than the private sector outsourced by the SUS. The number of CT tests in the SUS was less than half the number produced in developed countries. The results thus suggest the need for further studies on management practices with high-technology equipment in order to improve allocation of current and future public resources in supplying CT tests.
