    Full Text Available La irrigación de la cabeza del fémur ha sido motivo de algunos estudios anatomoclínicos, al mencionarse que ella sufriría necrosis aséptica, por la sección del ligamento de la cabeza del fémur y de sus vasos acompañantes (Moore, 1996. De acuerdo a la hipótesis en que la sección del ligamento de la cabeza del fémur junto a sus vasos podría afectar la nutrición perifoveolar de la cabeza, se efectuó un estudio anatomohistológico en un cerdo (Sus scrofa, de 3 meses de edad y 30 kg de peso, al que se seccionó quirúrgicamente el ligamento mencionado y las arterias que lo acompañan, las cuales también fueron ligadas. Después de 92 días y teniendo el cerdo un peso de 83 kg, fue sacrificado y se obtuvieron muestras para microscopia óptica del ligamento y de la cabeza del fémur, próxima a la fóvea. No fue posible observar alteraciones histopatológicas o necrosis aséptica en la zona de inserción del ligamento de la cabeza femoral y zonas adyacentes, tanto en la sustancias ósea compacta como esponjosa. Tampoco se observó alteración histopatológica en el cartílago articular. Fue observada sólo una moderada fibrosis en el extremo distal del ligamento de la cabeza femoral. La matriz ósea mostraba signos de mineralización activa. El lado control tampoco presentaba alteraciones histopatológicas. Este estudio mostró la escasa participación que tienen las arterias acompañantes del ligamento de la cabeza femoral en la irrigación perifoveolar de la cabeza del fémur en el cerdoThe irrigation of the perifoveolar region in the femoral head, has been the aim of some anatomo-clinic studies in the belief that it would suffer aseptic necrosis by the section of the ligament from the femoral head and from its relating vessels. In order to clarify the above hypothesis an anatomo-histological study was performed on a 3 months old, 30 kg pig specimen (Sus scrofa. This consisted in a surgical sectioning of the femur head ligament and its

    In this study, we report the complete mitochondrial genome sequence of the European wild boar, Sus scrofa scrofa for the first time. The genome is found to be 16,770 bp in length and has a base composition of A (34.63%), G (13.38%), C (26.21%), and T (25.78%), indicating that the percentage of A + T (60.41%) was higher than G + C (39.59%). Similar to other pigs, it contains a typically conserved structure including 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and 1 control region (D-loop). Most of the genes were located on the H-strand except for the ND6 gene and eight tRNA genes. The complete mitochondrial genome sequence provided here would add a new genetic resource and new study on the evolution of the genus Sus. PMID:25693697

    Full Text Available The discovery of new protein-coding DNA variants related to carcass traits is very important for the Italian pig industry, which requires heavy pigs with higher thickness of subcutaneous fat for Protected Designation of Origin (PDO productions. Exome capture techniques offer the opportunity to focus on the regions of DNA potentially related to the gene and protein expression. In this research a human commercial target enrichment kit was used to evaluate its performances for pig exome capture and for the identification of DNA variants suitable for comparative analysis. Two pools of 30 pigs each, crosses of Italian Duroc X Large White (DU and Commercial hybrid X Large White (HY, were used and NGS libraries were prepared with the SureSelectXT Target Enrichment System for Illumina Paired-End Sequencing Library (Agilent. A total of 140.2 M and 162.5 M of raw reads were generated for DU and HY, respectively. Average coverage of all the exonic regions for Sus scrofa (ENSEMBL Sus_scrofa.Sscrofa10.2.73.gtf was 89.33X for DU and 97.56X for HY; and 35% of aligned bases uniquely mapped to off-target regions. Comparison of sequencing data with the Sscrofa10.2 reference genome, after applying hard filtering criteria, revealed a total of 232,530 single nucleotide variants (SNVs of which 20.6% mapped in exonic regions and 49.5% within intronic regions. The comparison of allele frequencies of 213 randomly selected SNVs from exome sequencing and the same SNVs analyzed with a Sequenom MassARRAY® system confirms that this "human-on-pig" approach offers new potentiality for the identification of DNA variants in protein-coding genes.

  8. On the evolutionary consequences of increasing litter size with multiple paternity in wild boar (Sus scrofa scrofa).

    Understanding how some species may be able to evolve quickly enough to deal with anthropogenic pressure is of prime interest in evolutionary biology, conservation, and management. Wild boar (Sus scrofa scrofa) populations keep growing all over Europe despite increasing hunting pressure. In wild boar populations subject to male-selective harvesting, the initially described polygynous mating system may switch to a promiscuous/polyandrous one. Such a change in the mating system, where potentially more males sire a litter at one reproductive event, may be associated with the retention of high genetic diversity and an increase of litter size. We tested these hypotheses by estimating the number of sires per litter based on a six-year long monitoring of a wild boar population subject to particularly high harvesting pressure. Our results show a high and stable genetic diversity and high rates of multiple paternity compared to other populations, thus depicting a promiscuous/polyandrous mating system in this population. We also show that litter size is positively linked to the number of sires, suggesting that multiple paternity increases fecundity. We finally discuss that multiple paternity may be one of the factors allowing rapid evolution of this population by maintaining both genetic and phenotypic diversity. PMID:27166953

    Background Trichinella spp. infections in wild boar (Sus scrofa), one of the main sources of human trichinellosis, continue to represent a public health problem. The detection of Trichinella spp. larvae in muscles of wild boar by digestion can prevent the occurrence of clinical trichinellosis in humans. However, the analytical sensitivity of digestion in the detection process is dependent on the quantity of tested muscle. Consequently, large quantities of muscle have to be digested to warrant...

    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

    A wild boar (Sus scrofa) from the island Usedom in Mecklenburg-Western Pomerania (north-east Germany) was detected as Trichinella-positive during routine meat inspection. Encapsulated and non-encapsulated larvae were detected in the muscle tissue by trichinoscopy. In the diaphragm, 922 larvae per g were detected by artificial digestion. Muscle larvae displayed two different sizes of about 700 and 1100 microm. By a multiplex PCR analysis, larvae with a large size were identified as Trichinella spiralis, whereas those of a smaller size were identified as Trichinella pseudospiralis. This is the first finding of a mixed infection of T. spiralis and T. pseudospiralis in a naturally infected animal and it supports the tendency of more frequent detection of the non-encapsulated species T. pseudospiralis in Europe.

    Trichinella pseudospiralis is a non-encapsulated species infecting both mammals and birds. In Italy, this parasite was reported only in two night-birds of prey of Central Italy. In January 2010, Trichinella larvae were detected in three wild boars (Sus scrofa) of two regions of Northern Italy by enzymatic digestion. The parasites were identified as T. pseudospiralis by multiplex-PCR. The first infected wild boar was hunted in the Emilia Romagna region and the other two infected wild boars were bred outdoors in a small family farm of the Friuli Venezia Giulia region. These new epidemiological data reinforce the role of the wild boar as the main reservoir of T. pseudospiralis in Europe. PMID:21296503

    Fecal samples obtained from wild boar habitats are useful for the surveillance of diseases in wild boar populations; however, it is difficult to determine the species of origin of feces collected in natural habitats. In this study, a fecal IgA ELISA was evaluated as a method for identifying the porcine species from fecal samples. Both domestic pigs (Sus scrofa domestica) and wild boars (Sus scrofa coreanus) showed significantly higher levels of fecal IgA than other animal species. Additionally, age dependent changes in the level of Ig A in wild boars and domestic pigs were identified; Titers of Ig A were highest in suckling period and lowest in weanling period. PMID:27340389

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.

    Full Text Available Presented in this paper are the correlations between different soil parameters [presence of grubs, earthworms, pH, content of P2O5, K2O and organic matter (OM in soil] and wild boar (Sus scrofa [L.] damage to grasslands. The soil samples and damage assessments were performed at six locations in the Kočevje region, which is a densely wooded part of South East Slovenia. A significant positive correlation was discovered between the extent of damage due to wild boar rooting in grasslands and the number of grubs (r=0.73, the weight of grubs (r=0.69 and the content of P2O5 (r=0.87 in the soil. The quantity and weight of grubs in soil were significantly influenced by soil pH, the content of CaCl2 (r=0.71/0.72, P2O5 (r=0.90/0.91, and OM (r=0.74/0.77; while the quantity and weight of earthworms in soil were influenced by the content of K2O (r=0.81/-0.84. A moderate yet insignificant correlation (r=0.48/0.56 was discovered between the number and weight of earthworms in soil and the extent of grassland damage. Grubs represent a more important source of protein for wild boars than earthworms; consequently, reducing the quantity of grubs in soil could minimise the extent of damage caused by boars.

    This study investigated and evaluated the safety margins of the continuous long duration (up to 30 min) effect of the TASER X26 waveform, using a Sus scrofa model. Long duration continuous stimulus has not been evaluated on humans or human surrogates prior to this study. Swine were used as models due to similarities with humans in their skin and cardiovascular systems. Very long duration was used to determine both exposure dose and possible adverse physiological effects of dose. The trial began with an application of 10 min, and subsequent animals received increasing exposure time up to a survived maximum duration of 30 min. At the onset of this work, it was hypothesized that there would be a time limit after which most animals would not survive consistent with increased dose response. However, this hypothesis was not supported by the experimental results. All animals (10 of 10) survived up to 3 min. Seven of the 10 animals survived up to a 10-min exposure and 3 of 5 animals with a 30-min target exposure survived the full exposure. Surviving animals were recovered and observed for 24 h, with no postrecovery deaths. This suggests that swine (based on physiology) will not experience a fatal event when exposed to the TASER X26 for a continuous 3 min. Conclusions regarding longer duration (10-30 min) are not as certain due to the small sample sizes at these time intervals. PMID:23489132

    Juema pig is a kind of rare and special pig which is well adapted to high altitude, cold climate and harsh natural environment. The complete mitochondrial genome of Juema pig Sus scrofa is a circular molecule of 16 532 bp in length, containing 13 protein-coding genes, two ribosomal RNAs, 22 transfer RNAs, and a control region. The A + T content of the overall base composition of H-strand is 60.7% (T: 26.2%; C: 26.0%; A: 34.5%; G: 13.3%). ND4L gene begins with GTG as start codon, ND2, ND3, and ND5 genes begin with ATA as a start codon, and other nine protein-coding genes start with ATG. Cyt b gene is terminated with AGA as stop codon, ND1 and ND2 genes are terminated with TAG as stop codon, COII, COIII, ND3, and ND4 end with T, while ATP6, ATP8, COI, ND4L, ND5, and ND6 end with TAA. In addition, the phylogenetic relationships from neighbor-joining analyses based on the 13 concatenated PCGs indicated (Tylopoda (Suina (Ruminantia (Hippopotamidae, Cetacea)))). PMID:26359921

    In this study we establish a novel STR multiplex using 13 tetra-nucleotide STRs and the amelogenin marker for the forensic identification of pigs. The genotypes and allele frequency were generated based on 341 samples from 11 pig breeds in Taiwan. Genetic variation was tested including Na, Ne, Ho, He, F-statistics, PIC, Pm and PE for each STR locus and for each breed. Based upon the 341 samples in this study, the CPm and CPEtrio of the 13 STR loci were 1.31 E-11 and 0.9996 respectively. The CPItrio based on ten family sets ranged from 4.012 E+4 to 4.332 E+6 for paternity test. Validation of the multiplex included: determining the sensitivity of the test, where reproducible full DNA profiles were obtained using an initial template of between 0.25 and 1 ng; a comprehensive range of tissue types generated the same genotype; and the specificity was confirmed as no DNA full profile was generated for any species other than Sus scrofa. Based on the phylogenetic analysis, the European domestic breeds clustered separately from the Asian breeds, as expected, and their hybrids formed unique clades respectively between the clades of Asian and European breeds. Eleven test samples, acting as unknown samples, matched all expected breeds. We demonstrate that this novel 14-plex PCR system is valuable in pig individualization, parentage testing, breed assessment, phylogenetic study and forensic applications. PMID:24528574

    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

    Full Text Available Our study analyzed selected biometric characteristics from 117 wild boars (Sus scrofa ferus harvested during 2008 – 2014 in the Frasin and Marginea Forest hunting ground districts of Suceava County. Hunted boars were measured individually for head-body length (cm, height at withers (cm, length of metatarsus (cm, ear length (cm, tail length (cm and body weight (kg in accordance with their age-class and gender. These characteristics give information on the growth and development of wild boars and on the quality of their habitat. It was found that the average carcass weight was: piglets – 28.4 kg, yearling – 78.1 kg, subadults – 102.9 kg. The results show a faster body growth in females during their first year, while males make up for the weight difference in their 2nd and 3rd year. Statistical differences shown that males differentiate significantly to females by weight, body length, height at withers and length of metatarsus (P < 0.05 starting with their second year of life. The results regarding growth dynamic go along with the changes in boar’s social life, when the males are forced to leave and form smaller groups.

    Full Text Available The wild boar (Sus scrofa L. is native game in Croatia, whose population have tendency of increasing as well throughout the Europe. The wild boar is a natural inhabitant of Europe, Asia, and North Africa and is phylogenetically the ancestor of the domestic pig. Because of its phylogenetic and economic importance, this species is an interesting model for studying testis function. Therefore, the present study was performed to investigate the testis morphometry, and gonadosomatic index (GSI for 77 individuals. The mean live body weight was 75.03 kg, testis weight was 0.355 kg and with a gonadosomatic index (GSI of approximately 0.40%. The mean circumference for the left and right testes were not significant, but a significant and positive correlation was observed between testis weight and body weight (r = 0.88, p<0.05. A high reproductive contribution of juveniles is a likely consequence of a high hunting pressure rather than a species specific life history pattern characterizing wild boar. Generally, beside female seasonal reproductive activity knowledge of male reproduction cycle in wild boar is very important for established better management of free-ranging population.

    Full Text Available Aim: Identification of wild pig and domestic pig is essential to prevent illegal poaching of wild pig and to implement Wildlife (Protection Act, 1972. PCR-RFLP was used to differentiate Wild pig (Sus scrofa cristatus from Domestic pig (Sus scrofa domestica meat. Materials and Methods: DNA was isolated from meat samples of both the sub species and a fragment of Cytochrome b gene was amplified using universal primers and the PCR products were subjected to restriction digestion. Results: All the known samples of each of the sub-species amplified 474 bp fragment successfully using b1 and b2 primers. To differentiate between wild and domestic pig meat, restriction digestion of the PCR products was carried out to produce characteristic PCR-RFLP patterns for each species. StuI digestion yielded a RFLP pattern which distinguished the closely related sub species. The alignment of sequences of Wild pigs with sequences of local domestic pig, European wild pig and exotic breeds revealed 7 intra-species polymorphic sites within Cytochrome b gene fragment.Conclusion: This study showed that The PCR-RFLP is a simple and very effective tool for differentiating the samples of both the sub species and could prove to be a useful tool in forensic identification of wild pig and domestic pig.

    Full Text Available AbstractPorcine teschovirus (PTV, porcine sapelovirus (PSV, and enterovirus G (EV-G are infectious agents specific to pig host species that are endemically spread worldwide. This study aimed to investigate the natural infection by these porcine enteric picornaviruses in wild boars (Sus scrofa scrofa of Paraná state, Brazil, and to evaluate peccaries (Pecari tajacu and Tayassu pecari as alternative host species for these viruses. Fecal samples (n=36 from asymptomatic wild boars (n=22 with ages ranging from 2 to 7 months old (young, n=14 and 2 to 4 years old (adult, n=8 and from peccaries (6 to 8 months old, n=14 were collected from a farm and a zoo, respectively, both located in Paraná state. Reverse transcription-polymerase chain reaction (RT-PCR and nested-PCR (n-PCR assays targeting the 5'non-translated region of the virus genome were used for screening the viruses. Porcine enteric picornaviruses were detected in 12 out of the 22 wild boar fecal samples. According to each of the viruses, EV-G was most frequently (11/22, 50% detected, followed by PTV (10/22, 45.5% and PSV (4/22, 18.2%. Regarding the age groups, young wild boars were more frequently (9/14, 64.3% infected with PTV, PSV, and EV-G than adult animals (3/8, 37.4%. One n-PCR amplified product for each of the viruses was submitted to sequencing analysis and the nucleotide sequences were compared with the related viruses, which showed similarities varying from 97.7% to 100% for PTV, 92.4% to 96.2% for PSV, and 87.1% to 100% for EV-G. Peccaries tested negative for the viruses and in this study they did not represent infection reservoirs. This study is the first to report the molecular detection of PTV, PSV, and EV-G from captive wild boars in a South American country and the first to screen peccaries as alternative host species for porcine enteric picornavirus.

    Full Text Available This research aimed to investigate the DNA of food sources taken from blowfly (Chrysomya megacephala larval guts, for application in forensic entomology. The muscle samples of domestic swine (Sus scrofa, decomposed in 2 conditions, in air and drowning, were used as case studies. Adult blowflies were allowed to lay eggs on the meat samples. Then, the third instar larvae were identified as C. megacephala, then transferred to non-meat food and collected every 6 h up to 36 h. Total DNA extraction was performed by the Phenol-Chloroform method, and used as DNA templates in a Polymerase Chain Reaction (PCR test. The PCR amplified swine partial cytochrome b (cyt b genes with 203 bp expected size. The results showed that the swine DNA from blowfly larvae grown on decayed tissue under air and drowning conditions could be detected by PCR after larvae post-feeding up to 18 and 36 h, respectively. The sequence analysis revealed that the forward and reverse strands undergo 94 and 98 % identities of the swine cyt b gene sequence retrieved from nucleotide databases. This study suggests that mitochondrial DNA of the food source from insect guts can be detected at limited times after feeding, combined with the condition of the decayed tissues.

    The information conveyed in acoustic signals is a central topic in mammal vocal communication research. Body size is one form of information that can be encoded in calls. Acoustic allometry aims to identify the specific acoustic correlates of body size within the vocalizations of a given species, and formants are often a useful acoustic cue in this context. We conducted a longitudinal investigation of acoustic allometry in domestic piglets (Sus scrofa domesticus), asking whether formants of grunt vocalizations provide information concerning the caller's body size over time. On four occasions, we recorded grunts from 20 kunekune piglets, measured their vocal tract length by means of radiographs (X-rays) and weighed them. Controlling for effects of age and sex, we found that body weight strongly predicts vocal tract length, which in turn determines formant frequencies. We conclude that grunt formant frequencies could allow domestic pigs to assess a signaler's body size as it grows. Further research using playback experiments is needed to determine the perceptual role of formants in domestic pig communication. PMID:27059064

    As the number of free-living wild boars (Sus scrofa L.) continues to rise in Slovakia, the probability of pathogen transmission between susceptible species increases. We investigated the distribution and genetic characterization of porcine parvovirus type 3 (PPV3), porcine circovirus type 2 (PCV2), and their coinfection in wild boars. Among 194 animals tested, 19.1% were positive for PPV3 and 43.8% for PCV2. Similar rates of coinfection with both viruses reaching 11.0% and 11.8% were observed in juvenile and mature wild boars, respectively. Phylogenetic analysis of PPV3 sequences from VP1 and NS1 genomic regions revealed a close genetic relationship among isolates from Slovakia and those sampled worldwide. Prevalence of PCV2 in wild boars was lower than that reported in domestic pigs in Slovakia. The PCV2 variants originating from sylvatic and domestic hosts in Slovakia were grouped in the same clusters, namely PCV2b-1A/1B and PCV2a-2D. PMID:25973618

    Trichinellosis is a foodborne disease caused by the consumption of raw meat and raw meat-derived products from swine, horse and some game animals infected with nematode worms of the genus Trichinella. Between June 2006 and February 2011, 16 million domestic pigs and 0.22 million wild boars (Sus scrofa) were tested for Trichinella sp. in Hungary. Trichinella infection was not found in any pigs slaughtered for public consumption. Nevertheless, Trichinella spiralis was detected in four backyard pigs when trace back was done following a family outbreak. Trichinella infection was demonstrated in 17 wild boars (0.0077%). Larvae from wild boars were identified as Trichinella britovi (64.7%), T. spiralis (29.4%) and Trichinella pseudospiralis (5.9%). Although the prevalence of Trichinella sp. infection in wild boars and domestic pigs is very low, the spatial analysis reveals that the level of risk differs by region in Hungary. Most of the T. britovi infected wild boars (63.6%) were shot in the north-eastern mountain area of Hungary; whereas domestic pigs and wild boars infected with T. spiralis were detected only in the southern counties bordering Croatia and Romania. In the north-western and central counties, the prevalence of Trichinella infection seems to be negligible. PMID:21852037

    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.

    Wild pigs ( Sus scrofa ) are causing increasing ecologic and economic damage at a global scale. Because wild pigs can carry ≥65 diseases that affect livestock, their widespread expansion threatens native wildlife and livestock. We screened wild pigs from south-central Oklahoma, US for antibodies against Brucella abortus , pseudorabies virus (PRV), and porcine reproductive and respiratory syndrome virus (PRRS). These pathogens were chosen because they are part of eradication programs in the US and could have large economic impacts on domestic livestock if transmitted from wild animals. We tested 282 serum samples during spring 2010 (n=149) and 2011 (n=133) and found an overall exposure rate to PRV of 24.1% (n=68); PRV was detected at two of three study sites. Two wild pigs had detectable antibody to B. abortus , and one had detectable antibody to PRRS. On average, 27% of wild pigs within a sounder were positive for PRV antibody, with 44% of the sounders (16/36) having at least one positive individual. These data highlight that wild pigs could carry pathogens that affect domestic livestock. Because the US is free of these pathogens in commercial livestock operations, continued surveillance and vaccination of domestic livestock are needed. Commercial livestock producers at the wildlife-livestock interface may benefit from spatial prioritization of risk zones to facilitate strategic control efforts. PMID:27124329

    Several studies have demonstrated that wildlife reservoirs of mycobacteria are responsible for the maintenance and spreading of the infection to livestock and wildlife counterparts. Recent data report the role of wild boar (Sus scrofa) as a reservoir for Mycobacterium bovis. This study was conducted to evaluate the chronic inflammatory response in the mesenteric lymph nodes (MLN) of wild boar with granulomatous lymphadenitis (n=30). Morphological parameters of the lesions were recorded. The expression of CD3 and CD79α molecules was evaluated by immunohistochemistry. Molecular genotyping and culture to identify mycobacteria were performed. The lesions consisted mainly of stage III and stage IV granulomas. CD3 and CD79α positive cells were observed in 15 (50%) and in 11 (36.6%) MLN, respectively. In these lesions, higher percentages of T lymphocytes were found and a limited number of animals exhibited a tendency for an increased percentage of B lymphocytes. Our results suggest that there are similar percentages and distribution patterns of CD3 and CD79α in the lesions, regardless of the presence of Mycobacterium avium subsp. paratuberculosis (Map), M. bovis or Map-M. bovis co-infection, and confirm that wild boar is both susceptible and could be an important Map and M. bovis wild reservoir in the study area.

    Full Text Available In order to discuss the subspecies classification of wild boar Sus scrofa in China, We studied their genetic structure using 11 microsatellites, with emphasis on South China. High levels of genetic variationwere detected in South China (SC, North China (NC and Northeast China (NE wild boar populations. This was consistent with the huge population size of the wild boar and its status as a widely-distributed species. Weak genetic divergence was observed in all subspecies involved in this study. Individuals from all subspecies were highly mixed in the phylogeny tree based on the allele sharing distance (DAS, no distinct clade was found according to the defined subspecies. Even considering the two main factors, which reflect the biggest genetic differentiation among the populations, it is impossible to distinguish SC,NC and NE from each other by FCA (Factor Correspondence Analysis. Using the F-statistic test, weak genetic differentiation (Fst = 0.014 was detected between SC and NC population, which indicated a high gene flow between two sides of the Yangtze River. The Yangtze River is an insurmountable geographical hindrance for wild boars. The stronger population differentiations were observed between NE and NC population, and between NE and SC population(Fst = 0.040, 0.042 respectively), this may suggest that the wild boars in NE area could be defined as the subspecies S. s. ussuricus.[Acta Zoologica Sinica 54(5: 753 – 761, 2008].

    Sarcoptic mange occurs in free-ranging wild boar (Sus scrofa) but has been poorly described in this species. We evaluated the performance of a commercial indirect enzyme-linked immunosorbent assay (ELISA) for serodiagnosis of sarcoptic mange in domestic swine when applied to wild boar sera. We tested 96 sera from wild boar in populations without mange history ("truly noninfected") collected in Switzerland between December 2012 and February 2014, and 141 sera from free-ranging wild boar presenting mange-like lesions, including 50 live animals captured and sampled multiple times in France between May and August 2006 and three cases submitted to necropsy in Switzerland between April 2010 and February 2014. Mite infestation was confirmed by skin scraping in 20 of them ("truly infected"). We defined sensitivity of the test as the proportion of truly infected that were found ELISA-positive, and specificity as the proportion of truly noninfected that were found negative. Sensitivity and specificity were 75% and 80%, respectively. Success of antibody detection increased with the chronicity of lesions, and seroconversion was documented in 19 of 27 wild boar sampled multiple times that were initially negative or doubtful. In conclusion, the evaluated ELISA has been successfully applied to wild boar sera. It appears to be unreliable for early detection in individual animals but may represent a useful tool for population surveys. PMID:26161723

    Full Text Available This study aims to discover more about the arterial supply of cervical lobes of the thymus, in relation to its origins, distribution and ordination in swine (Sus scrofa domesticus of Camborough 25 lineage. Thus, 29 swine (17 males and 12 females were studied. The arterial system of the models was colored with aqueous solution of Neoprene Latex “450” (50% and after the models were fixed in 10% formaldehyde aqueous solution. Great individual variations in the length and size of the thymus vessel supply, and also in the layout, size and thickness of the cervical lobes of the thymus, were observed. The superficial cervical artery (96.55%, common carotid artery (54.54% and occipital artery (55.17% contribute to the blood supply of the cervical lobes on both sides. In addition, branches from the lingual artery (3.45% and internal carotid artery (3.45% on both sides, as well as the subclavian artery (6.90% on the left side, were observed. No significant differences in vascularization of lobes in relation to antimerals or sexes were evidenced. Considering the findings, it was conclued that each animal had its own characteristics and peculiarities, thus enabling the establishment of a particular arrangement of the swine strain.

    Full Text Available BACKGROUND: To obtain robust epidemiological information regarding tuberculosis (TB in wildlife species, appropriate diagnostic methods need to be used. Wild boar (Sus scrofa recently emerged as a major maintenance host for TB in some European countries. Nevertheless, no data is available to evaluate TB post-mortem diagnostic methods in hunter-harvested wild boar. METHODOLOGY/PRINCIPAL FINDINGS: Six different diagnostic methods for TB were evaluated in parallel in 167 hunter-harvested wild boar. Compared to bacteriological culture, estimates of sensitivity of histopathology was 77.8%, gross pathology 72.2%, PCR for the MPB70 gene 66.7%, detection of acid-fast bacilli (AFB in tissue contact smears 55.6% and in histopathology slides 16.7% (estimated specificity was 96.7%, 100%, 100%, 94.4% and 100%, respectively. Combining gross pathology with stained smears in parallel increased estimated sensitivity to 94.4% (94.4% specificity. Four probable bacteriological culture false-negative animals were identified by Discriminant Function Analysis. Recalculating the parameters considering these animals as infected generated estimated values for sensitivity of bacteriology and histopathology of 81.8%, gross pathology 72.7%, PCR for the MPB70 gene 63.6%, detection of AFB in tissue contact smears 54.5% and in histopathology slides 13.6% (estimated specificity was 100% for gross pathology, PCR, bacteriology and detection of AFB in histopathology slides, 96.7% for histopathology and 94.4% for stained smears. CONCLUSIONS/SIGNIFICANCE: These results show that surveys for TB in wild boar based exclusively on gross pathology considerably underestimate prevalence, while combination of tests in parallel much improves sensitivity and negative predictive values. This finding should thus be considered when planning future surveys and game meat inspection schemes. Although bacteriological culture is the reference test for TB diagnosis, it can generate false

    Mercury (Hg) is likely bound to large biomolecules (e.g. proteins) in living organisms, and in order to assess Hg metabolic pathways and possible toxicological effects, it is essential to study these Hg containing biomolecules. However, the exact nature of most metal binding biomolecules is unknown. Such studies are still in their infancy and information on this topic is scarce because the analysis is challenging, mainly due to their lability upon digestion or extraction from the tissue. New analytical methods that allow complex Hg-biomolecules to be analysed intact are needed and only few very recent studies deal with this approach. Therefore, as an initial step towards the characterization of Hg containing biomolecules, an analytical procedure has been optimised using size-exclusion chromatography (SEC) with inductively coupled plasma mass spectrometry (ICP-MS) detection. We applied this technique to elucidate the distribution and elution profile of Hg and Se, and some physiological important elements such as Fe, Ni, Zn and Cu, to assess metal binding profiles in liver and kidney samples of red deer (Cervus elaphus) and wild boar (Sus scrofa) who roam freely within the largest Hg mining district on Earth, Almadén in Spain. Elemental fractionation profiles of the extracts from different tissues were obtained using two different SEC columns (BioSep-SEC-S2000 GL 300-1kDa and Superdex 75 10/300 GL 70-3kDa). Similar profiles of Hg were observed in red deer and wild boar; however, significant differences were evident for liver and kidney. Moreover, the profiles of Se showed a single peak at high-medium molecular weight in all investigated tissues, while co-elution of Hg with Fe, Ni, Zn and Cu was observed. PMID:27093497

    Wild boar (Sus scrofa) populations are increasing in the Iberian Peninsula, and population management must include disease management and control. In this study, the epidemiology of 10 selected pathogens (Aujeszky's disease virus - ADV, porcine reproductive and respiratory syndrome virus - PRRSV, porcine influenza virus, porcine circovirus, porcine parvovirus, Erysipelotrix rhusiopathiae, Leptospira pomona, Chlamydia/Chlamydiaceae sp., Salmonella sp. and Mycobacterium bovis) in the wild boar population in Sierra Nevada National Park (SNNP), an open unfenced area, is reported, taking into account wild boar population abundance variation in space and time in an open unfenced environment. A total of 1103 wild boar were sampled in 141 hunting events randomly carried out for sampling in seven hunting seasons (October to February from 2002-2003 to 2009-2010 (except 2007-2008). Prevalence was overall lower than those previously reported for fenced wild boar populations in Spain, but all the pathogens analyzed except PRRSV were considered endemic in the SNNP. ADV, E. rhusiopathiae and total pathogen prevalence were positively correlated to wild boar density. Prevalence in the positive areas was significantly higher in females for ADV, E. rhusiopathiae, L. pomona, Chlamydia/Chlamydiaceae sp. and Salmonella sp., and in males for M. bovis. This longitudinal study provides the first data on the health status of the relatively unmanaged and low density wild boar population of SNNP. It is concluded that non-intensively managed wild boar populations are able to maintain the circulation of several pathogens, even in low prevalences and in open unfenced areas with natural density variation both in time and space.

    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).

    Full Text Available Trichinellosis is one of the most serious foodborne parasitic zoonoses in Europe. Wild carnivorous and omnivorous hosts are the main reservoirs of Trichinella spp. nematodes in nature. In the winter of 2008-2009, an atypical clinical case of trichinellosis occurred for the consumption of pork from a wild boar (Sus scrofa hunted in southwestern Alps in Italy. The symptomatic individual showed delayed development of oedemas in the lower limbs and eosinophilia, which appeared three months after infection. Muscle samples harboured 3.8 larvae/g, which were identified as Trichinella britovi. During the epidemiological investigation, anti-Trichinella IgG were detected in five hunters.

However, there is no available information on the genetic potential of these animals in terms of potential lean tissue growth.The aim of the study was to determine the maximum capacity for protein deposition (operational PDmax in wild boars under controlled environmental conditions. Four diets were formulated containing different levels of digestible energy (DE: 2.2, 2.4, 2.6, and 2.8 Mcal DE kg-1. All of the diets contained at least 5 g lysine per Mcal DE. Twenty purebred wild boars from a commercial farm of the same age (± 4 d and with an initial liveweight of 27 ± 0.50 kg (mean ± standard error of the mean were used in the study. At the beginning of the study (day 1, four animals were sacrificed and the carcasses were frozen without the digestive tract contents. The remaining animals were divided in foursomes and received each of the four diets over a 28-d period; they were then sacrificed and the carcasses were frozen without the digestive tract contents. All of the carcasses were ground and analyzed for DM, crude protein, ether extract, and ash. Protein deposition of the animals sacrificed on day 28 was determined as the difference between crude protein content estimated for the animals on day 1 using data from the animals sacrificed on day 1 and protein content of animals sacrificed on day 28. It was not possible to determine PDmax due to the genetic heterogeneity of the animals. Further studies on PDmax in wild boars must be carried out following genetic selection and breeding to produce more homogeneous animals.La tasa de crecimiento del jabalí Europeo (Sus scrofa L. se considera muy baja.

    Full Text Available Wild boar is a host of a number of arthropod-vectored diseases and its numbers are on the rise in mainland Europe. The species potentially impacts ecosystems, humans and farming practices and so its distribution is of interest to policy makers in a number of fields beyond that of the primarily epidemiological goal of this study. Three statistical model outputs describing the distribution and abundance of the species Sus scrofa (Wild boar are included in this data package. The extent of this dataset covers continental Europe. These data were presented as a poster [1] at the conference Genes, Ecosystems and Risk of Infection (GERI 2015. The first of the three models provide a European map presenting the probability of presence of Sus scrofa, which can be used to describe the likely geographical distribution of the species. The second and third models provide indices to help describe the likely abundance across the continent. The two indices include “the proportion of suitable habitat where presence is estimated” and a simple classification of boar abundance across Europe using quantiles of existing abundance data and proxies.

    The objective of this study was to identify loci associated with tail biting or being a victim of tail biting in Norwegian crossbred pigs using a genome-wide association study with PLINK case-control analysis. DNA was extracted from hair or blood samples collected from 98 trios of crossbred pigs located across Norway. Each trio came from the same pen and consisted of one pig observed to initiate tail biting, one pig which was the victim of tail biting and a control pig which was not involved in either behaviour. DNA was genotyped using the Illumina PorcineSNP60 BeadChip whole-genome single-nucleotide polymorphism (SNP) assay. After quality assurance filtering, 53,952 SNPs remained comprising 74 animals (37 pairs) for the tail biter versus control comparison and 53,419 SNPs remained comprising 80 animals (40 pairs) for the victim of tail biting versus control comparison. An association with being a tail biter was observed on Sus scrofa chromosome 16 (SSC16; p = 1.6 × 10(-5)) and an unassigned chromosome (p = 3.9 × 10(-5)). An association with being the victim of tail biting was observed on Sus scrofa chromosomes 1 (SSC1; p = 4.7 × 10(-5)), 9 (SSC9; p = 3.9 × 10(-5)), 18 (SSC18; p = 7 × 10(-5) for 9,602,511 bp, p = 3.4 × 10(-5) for 9,653,881 bp and p = 5.3 × 10(-5) for 29,577,783 bp) and an unassigned chromosome (p = 6.1 × 10(-5)). An r(2) = 0.96 and a D' = 1 between the two SNPs at 9 Mb on SSC18 indicated extremely high linkage disequilibrium, suggesting that these two markers represent a single locus. These results provide evidence of a moderate genetic association between the propensity to participate in tail-biting behaviour and the likelihood of becoming a victim of this behaviour.

    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

    In an earlier study, we found significant changes in red-blood-cell, leukocyte, and platelet counts, and in red-blood-cell membrane proteins, following exposures of anesthetized pigs to a conducted electrical weapon. In the current study, we examined potential changes in plasma proteins [analyzed via two-dimensional gel electrophoresis (2-DGE)] following two 30 s exposures of anesthetized pigs (Sus scrofa) to a TASER (®) C2 conducted electrical weapon. Patterns of proteins, separated by 2-DGE, were consistent and reproducible between animals and between times of sampling. We determined that the blood plasma collection, handling, storage, and processing techniques we used are suitable for swine blood. There were no statistically significant changes in plasma proteins following the conducted-electrical-weapon exposures. Overall gel patterns of fibrinogen were similar to results of other studies of both pigs and humans (in control settings, not exposed to conducted electrical weapons). The lack of significant changes in plasma proteins may be added to the body of evidence regarding relative safety of TASER C2 device exposures. PMID:25319243

    Mycobacterium bovis bacille Calmette-Guerin (BCG) is being considered for vaccination of feral swine (Sus scrofa ssp.). Since BCG is a live bacterium, evaluation of its safety and persistence in tissues is important. Fifteen feral swine received approximately 4.5 × 10(6) colony forming units of BCG Danish via oral bait. Four animals received bait without BCG. At 1, 3, 6, and 9 months post-vaccination, four vaccinates were euthanized. Non-vaccinates were euthanized at 9 months. Clinical signs were not noted in vaccinated pigs at any time. Tissues from all 20 pigs were culture-negative for mycobacteria. Based on our data, BCG is safe and appears not to persist in feral swine tissues after one month post-oral vaccination. However, further work must be performed at higher doses, and on a larger number of animals representing the target population, and further evaluation of persistence in tissues within the first month post-vaccination is needed.

    Full Text Available Abstract Background Lymphocyte function-associated antigen-1 (LFA-1, CD11a/CD18, alphaLbeta2, the most abundant and widely expressed beta2-integrin, is required for many cellular adhesive interactions during the immune response. Many studies have shown that LFA-1 is centrally involved in the pathogenesis of several diseases caused by Repeats-in-toxin (RTX -producing bacteria. Results The porcine-LFA-1 CD11a (alpha subunit coding sequence was cloned, sequenced and compared with the available mammalian homologues in this study. Despite some focal differences, it shares all the main characteristics of these latter. Interestingly, as in sheep and humans, an allelic variant with a triplet insertion resulting in an additional Gln-744 was consistently identified, which suggests an allelic polymorphism that might be biologically relevant. Conclusion Together with the pig CD18-encoding cDNA, which has been available for a long time, the sequence data provided here will allow the successful expression of porcine CD11a, thus giving the first opportunity to express the Sus scrofa beta2-integrin LFA-1 in vitro as a tool to examine the specificities of inflammation in the porcine species.

    Laser fluorescence activated slit-scan flow cytometry offers an approach to a fast, quantitative characterization of chromosomes due to morphological features. It can be applied for screening of chromosomal abnormalities. We give a preliminary report on the development of the Heidelberg slit-scan flow cytometer. Time-resolved measurement of the fluorescence intensity along the chromosome axis can be registered simultaneously for two parameters when the chromosome axis can be registered simultaneously for two parameters when the chromosome passes perpendicularly through a narrowly focused laser beam combined by a detection slit in the image plane. So far automated data analysis has been performed off-line on a PC. In its final performance, the Heidelberg slit-scan flow cytometer will achieve on-line data analysis that allows an electro-acoustical sorting of chromosomes of interest. Interest is high in the agriculture field to study chromosome aberrations that influence the size of litters in pig (Sus scrofa domestica) breeding. Slit-scan measurements have been performed to characterize chromosomes of pigs; we present results for chromosome 1 and a translocation chromosome 6/15.

    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.

    The presence of serum antibodies directed against classical swine fever (CSF) virus and other pestiviruses among the wild boar (Sus scrofa) population in Croatia was investigated. During 2003, serum samples from 214 wild boars were collected in 10 hunting areas in the continental part of the country. The sera were examined by enzyme immunoassay (ELISA) and in the virus neutralization test (VNT). Out of 214 sera tested 111 (51.87 %) were positive by ELISA and regarding neutralising antibodies, against CSFV 75 (35.05 %) samples were positive. In the VNT with the C-strain (conventional live vaccine strain China) and the strain Uelzen were used. Samples were also tested for neutralizing antibodies against border disease virus (BDV) using the strain 137/4 and against bovine viral diarrhoea virus (BVDV) using the NADL strain. Neutralizing antibodies against the C-strain were detected in 36 sera (16.82 %), against strain Uelzen in 17 sera (7.94 %) and in 22 sera (10.28 %) against both strains. In five sera (2.33 %) neutralizing antibodies against BVDV and BDV were found. PMID:17484502

    In previous studies hematocrit has been consistently increased in an anesthetized animal model after exposures to TASER(®) conducted energy weapons (CEWs). In the present study we analyzed changes in blood cell counts and red blood cell membrane proteins following two 30-s applications of a TASER C2 device (which is designed for civilian use). Hematocrit increased significantly from 33.2 ± 2.4 (mean ± SD) to 42.8 ± 4.6 % immediately after CEW exposure of eleven pigs (Sus scrofa). Red blood cell count increased significantly from 6.10 ± 0.55 × 10(12)/L to 7.45 ± 0.94 × 10(12)/L, and mean corpuscular volume increased significantly from 54.5 ± 2.4 fl to 57.8 ± 2.6 fl. Mean corpuscular hemoglobin concentration decreased significantly from 20.5 ± 0.7 to 18.5 ± 0.6 mM. Thirty protein spots (from two-dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis, selected for detailed comparison) exhibited greater densities 30-min post-exposure compared with pre-exposure values. A greater number of echinocytes were observed following CEW exposure. On the basis of these results it appears that, during the strong muscle contractions produced by TASER CEWs, a specific population of red blood cells (RBCs) may be released from the spleen or other reservoirs within the body. The total time of CEW exposure in the present study was relatively long compared with exposures in common law-enforcement scenarios. Despite statistically significant changes in red blood cell counts (and other measures directly related to RBCs), the alterations were short-lived. The transient nature of the changes would be likely to counteract any potentially detrimental effects. PMID:23543463

    Livestock distribution in the United States (U.S.) can only be mapped at a county-level or worse resolution. We developed a spatial microsimulation model called the Farm Location and Agricultural Production Simulator (FLAPS) that simulated the distribution and populations of individual livestock farms throughout the conterminous U.S. Using domestic pigs (Sus scrofa domesticus) as an example species, we customized iterative proportional-fitting algorithms for the hierarchical structure of the U.S. Census of Agriculture and imputed unpublished state- or county-level livestock population totals that were redacted to ensure confidentiality. We used a weighted sampling design to collect data on the presence and absence of farms and used them to develop a national-scale distribution model that predicted the distribution of individual farms at a 100 m resolution. We implemented microsimulation algorithms that simulated the populations and locations of individual farms using output from our imputed Census of Agriculture dataset and distribution model. Approximately 19% of county-level pig population totals were unpublished in the 2012 Census of Agriculture and needed to be imputed. Using aerial photography, we confirmed the presence or absence of livestock farms at 10,238 locations and found livestock farms were correlated with open areas, cropland, and roads, and also areas with cooler temperatures and gentler topography. The distribution of swine farms was highly variable, but cross-validation of our distribution model produced an area under the receiver-operating characteristics curve value of 0.78, which indicated good predictive performance. Verification analyses showed FLAPS accurately imputed and simulated Census of Agriculture data based on absolute percent difference values of farm-to-county scale. Our output data have many applications for risk management of agricultural systems including epidemiological studies, food safety, biosecurity issues, emergency

  15. Utilization of sugarcane habitat by feral pig (Sus scrofa in northern tropical Queensland: evidence from the stable isotope composition of hair.

    Christopher M Wurster

    Full Text Available 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 δ(13C and δ(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.

  17. Accumulation and distribution of 137Cs and 90Sr in the body of the wild boar (Sus scrofa) found on the territory with radioactive contamination

    International Nuclear Information System (INIS)

    We studied the concentration and distribution of 137Cs and 90Sr 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 137Cs 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 137Cs was detected in the muscle tissue and kidneys taken animals. In some samples of muscle tissue it reached more than 660 kBq/kg. The 137Cs 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 137Cs was found in the lungs and skin of animals. The analyses of 90Sr concentration in the organs and tissues of the wild boar showed that 90Sr was concentrated mainly in the bone tissue. The average level of 90Sr 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 90Sr – 30.0–110.0 Bq/kg in the Alienation Zone and 11.0–30.0 Bq/kg in the Permanent Control zone

    Full Text Available This research is the first comparative chromosome analysis report of Thai wild boar (Sus scrofa jubatus and its relationship to domestic pig (S. s. domestica by conventional staining, G-banding and high-resolution technique. Blood samples of the Thai wild boar were taken from two males and two females kept in Nakhon Ratchasima Zoo. After standard whole blood lymphocyte culture at 37 oC for 72 hr. in the presence of colchicine, the metaphase spreads were performed on microscopic slides and airdried. Conventional staining, G-banding and high-resolution technique were applied to stain the chromosomes. The results showed that the number of diploid chromosomes of Thai wild boar was 2n (diploid = 38, and the fundamental numbers (NF were 62 in the male and female. The type of autosomes were 12 metacentric, 14 submetacentric, 4 acrocentric and 6 telocentric chromosomes, with X and Y chromosomes being metacentric chromosomes. We found that chromosomes 1, 5, 7, 8, 10, 11, 12, 13, 14, 16, 17, 18, X and Y had the same Gbanding and high-resolution technique patterns as those of domestic pig chromosomes. Chromosomes 2, 3, 4, 6, 9 and 15 are similar to those of domestic pig chromosomes. These results show the evolutionary relationship between the Thai wild boar and the domestic pig.

    Enzootic pneumonia (EP) caused by Mycoplasma hyopneumoniae has a significant economic impact on domestic pig production. A control program carried out from 1999 to 2003 successfully reduced disease occurrence in domestic pigs in Switzerland, but recurrent outbreaks suggested a potential role of free-ranging wild boar (Sus scrofa) as a source of re-infection. Since little is known on the epidemiology of EP in wild boar populations, our aims were: (1) to estimate the prevalence of M. hyopneumoniae infections in wild boar in Switzerland; (2) to identify risk factors for infection in wild boar; and (3) to assess whether infection in wild boar is associated with the same gross and microscopic lesions typical of EP in domestic pigs. Nasal swabs, bronchial swabs and lung samples were collected from 978 wild boar from five study areas in Switzerland between October 2011 and May 2013. Swabs were analyzed by qualitative real time PCR and a histopathological study was conducted on lung tissues. Risk factor analysis was performed using multivariable logistic regression modeling. Overall prevalence in nasal swabs was 26.2% (95% CI 23.3-29.3%) but significant geographical differences were observed. Wild boar density, occurrence of EP outbreaks in domestic pigs and young age were identified as risk factors for infection. There was a significant association between infection and lesions consistent with EP in domestic pigs. We have concluded that M. hyopneumoniae is widespread in the Swiss wild boar population, that the same risk factors for infection of domestic pigs also act as risk factors for infection of wild boar, and that infected wild boar develop lesions similar to those found in domestic pigs. However, based on our data and the outbreak pattern in domestic pigs, we propose that spillover from domestic pigs to wild boar is more likely than transmission from wild boar to pigs. PMID:25747151

    Full Text Available O objetivo desse estudo foi descrever o quadro clínico e epidemiológico, os achados patológicos, bacteriológicos e imuno-histoquímicos de um surto de pneumonia em uma granja de Javalis do Distrito Federal, Brasil. Em um período de cinco meses, morreram 90 javalis. Desses, 63 tinham lesões pulmonares. Clinicamente apresentavam atraso no desenvolvimento corporal, diminuição do apetite, letargia, tosse e dificuldade respiratória, principalmente quando movimentados. Constatou-se elevação da temperatura, 40ºC em média. Na auscultação, havia crepitações e estertores pulmonares de intensidade moderada. As alterações macroscópicas nos pulmões analisados eram típicas de broncopneumonia lobular. As lesões caracterizavam-se por consolidação crânio-ventral na maioria dos pulmões. A coloração variava de difusamente vermelho-escuro a um padrão mosaico (lóbulos vermelho-escuros intercalados por lóbulos cinzas ou difusamente acinzentados. Na maioria dos pulmões observou-se exsudato mucopurulento na luz dos brônquios e fluindo do parênquima. Histologicamente, as alterações eram de broncopneumonia purulenta e histiocitária com focos de necrose. Em alguns animais havia também hiperplasia do BALT e, na maioria dos animais, infiltração linfocítica perivascular e peribronquial. Bordetella bronchiseptica e Streptococcus spp. foram as principais bactérias isoladas. A imuno-histoquímica demonstrou a bactéria Mycoplasma hyopneumoniae no epitélio bronquiolar e bronquial e o DNA desta bactéria foi detectado pela PCR. Este é o primeiro relato de broncopneumonia em Javalis associado à infecção por M. hyopneumoniae.The aim of this paper is to describe the clinical, epidemiological, pathological, bacteriological and immunohistochemical aspects of a pneumonia outbreak in a wild pig farm in the Distrito Federal, Brazil. Ninety wild pigs died in a period of five months, and 63 of these had pulmonary lesions. Clinically, the pigs presented reduced growth rate, anorexia, lethargy, cough and dyspnea, especially after they were moved. High body temperature (40ºC in average was verified in some animals. Auscultation revealed moderate pulmonary crepitation and stertors. Pulmonary gross lesions were typical of lobular bronchopneumonia. Lung lesions were characterized by ventral-cranial consolidation in the majority of the cases. The color of affected pulmonary areas varied from diffuse dark red to mosaic pattern (dark red lobule intercalate by grayish lobule or diffusely grayish. The majority of the lungs had mucopurulent exsudate in the bronchial lumen that also drained from the parenchyma cut surface. Upon microscopy, the changes were characterized by purulent and histiocytic bronchopneumonia with necrotic foci. In some animals, there was BALT hyperplasia associated with perivascular and peribronchial plasma cells and lymphocytes infiltration in most of these cases. Bordetella bronchiseptica and Streptococcus spp. were the most frequently isolated bacteria. Immunohistochemistry evaluation demonstrated Mycoplasma hyopneumoniae on the luminal surface of bronchial and bronchiolar epithelial cells, and the DNA of bacteria was detected by PCR. This is the first report of bronchopneumonia in wild boars associated with M. hyopneumoniae infection.

    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

    The Eurasianwild boar has experienced aworldwide demographic explosion that increases awareness on shared pathogens. However, shedding routes of relevant wild boar pathogens are unknown. Previous observations on sex- and age-related differences in Aujeszky's disease virus (ADV) exposure led us to hypothesize that shedding patterns of endemicwild boar pathogens may be influenced by individual traits.We investigated shedding routes of ADV, porcine parvovirus (PPV), porcine circovirus type 2 (PCV2) and Coxiella burnetii and analysed the effect of host sex and age on pathogen shedding patterns. The presence of pathogen antibodies in serumand of pathogen DNA in oral, nasal, genital and rectal swabswas analysed by ELISA and PCR, respectively. The influence of sex and age in pathogen shedding prevalencewas tested statistically.Main routes of ADV, PPV, PCV2 and C. burnetii shedding were identified but the hypothesis of sex- and/or age-related shedding patterns couldn't be confirmed.

En esta forma, a ¡la par que se ayudaría a resolver el problema de la alimentación, se fortalecería en forma notable la economía nacional mediante el aprovechamiento completo de los productos y subproductos agrícolas que hoy en muchos casos se desperdician lamentablemente. Aparte del mercado nacional, susceptible de un aumento vertical en la demanda, Colombia puede pensar seriamente, por poseer grandes extensiones de terrenos aptos para esta explotación y contar con productos agrícolas de muy buenas características para la alimentación de cerdos, en convertirse en un emporio porcino de primer orden. En la actualidad nuestras explotaciones de ganado de cerda son rudimentarias y enfrentan problemas de diferente índole tales como enfermedades, deficiente alimentación, falta de selección, etc., problemas estos que hacen que la producción de cerdo sea inferior a nuestras necesidades. Pero este hecho que es una de las tantas demostraciones del retraso de nuestras industrias pecuarias, puede ser remediado fácilmente con un programa de capacitación de los productores actuales o potenciales del cerdo.

La dieta está representada por animales, vegetales y hongos. Entre los vegetales y hongos son consumidas tanto las partes epígeas como hipógeas, lo mismo que frutos y semillas. Hongos y rizomas de Gunnera tinctoria constituyen ítemes vegetales cuantitativamente importantes en la alimentación. El jabalí forrajea en general en ambiente boscoso, pero las especies vegetales más frecuentes en la dieta se encuentran en espacios abiertos o fuera del bosque. El ambiente dominado por Chusquea spp. constituye un importante sitio de alimentación. Los roedores de la familia Muridae dominan entre los animales determinados en la dieta del jabalí. Esta situación, sin embargo, parece obedecer a la ocurrencia de una ratada producto de la semillación masiva de Chusquea spp. durante la época de muestreo. Las aves de la familia Rhinocryptidae e invertebrados (en especial larvas del coleóptero Chiasognathus grantii constituyen parte frecuente de los ítemes animales de la dieta del jabalí. En comparación a estudios en otras partes del mundo, el jabalí silvestre en Chile consume hongos en porcentaje de ocurrencia similar (65 % a su dieta en Estados Unidos de América pero bastante más alta que su dieta en Europa (5-32 %. En relación al volumen del componente animal, el jabalí en Chile consume más (16,1 % que en Estados Unidos de América (6 % y que en Europa (7-13 %We document the diet of wild boar in south-central Chile based on analysis of 20 stomachs collected on the outskirts of Mocho-Choshuenco volcano (39°54' S, 72°02' W and of Vicente Pérez Rosales National Park (41°03' S, 71°54' W. The diet incorporates animals, plants and fungi. Among the latter two, both epigeal and hypogeal parts are consumed, together with fruits and seeds. Fungi and rhizomes of Gunnera tinctoria are the most abundant plant items in the diet. The wild boar in Chile forages chiefly in forested environments, but nonetheless the most frequent plant items in its diet are found in open spaces or outside the forest. Environments dominated by bamboos Chusquea spp. constitute important foraging sites. Rodents in the family Muridae prevail among animal items in the wild boar diet. This situation, however, is associated to the occurrence of a mouse outbreak (ratada resulting from the mast seeding of Chusquea spp. during our study. Birds in the family Rhinocryptidae together with invertebrates (specially Coleopteran larvae of Chiasognathus grantii made up a sizeable part of the animals in the wild boar diet. In comparison to elsewhere, the wild boar in Chile consumes fungi in a similar percentage of occurence (65 % as in the United States of America but much higher than in Europe (5-32 %.

In total, 22 (50% wild boars were PCR positive. Sequencing of the amplicons identified Chlamydia suis and Chlamydia pecorum in 12 and 5 samples, respectively. For one sample found PCR positive, the nucleotide sequence could not be determined. Four conjunctival samples showed ≥ 92% sequence similarities to 16S rRNA sequences from Chlamydia-like organisms, as did large intestine, uterus, and vaginal swabs from the same four animals. Amoeba DNA was found in one Chlamydia-like organism positive conjunctival swab. To our knowledge, this is the first detection of members of the Parachlamydiaceae family in wild boars, confirming a large animal host range for Chlamydia-like organisms.

    Pigs were infected with a Bolivian strain of Trypanosoma cruzi (genotype I) and evaluated up to 150 days postinoculation (dpi) to determine the use of pigs as an animal model of Chagas disease. Parasitemia was observed in the infected pigs during the acute phase (15-40 dpi). Anti-T. cruzi immunoglobulin M was detected during 15-75 dpi; high levels of anti-T. cruzi immunoglobulin G were detected in all infected pigs from 75 to 150 dpi. Parasitic DNA was observed by western blot (58%, 28/48) and polymerase chain reaction (27%, 13/48) in urine samples, and in the brain (75%, 3/4), spleen (50%, 2/4), and duodenum (25%, 1/4), but no parasitic DNA was found in the heart, colon, and kidney. Parasites were not observed microscopically in tissues samples, but mild inflammation, vasculitis, and congestion was observed in heart, brain, kidney, and spleen. This pig model was useful for the standardization of the urine test because of the higher volume that can be obtained as compared with other small animal models. However, further experiments are required to observe pathological changes characteristic of Chagas disease in humans. PMID:26928841

    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.

The average values obtained for the tongue length, tongue weight, rasp length, left pinna length, right pinna length, left pinna width, right pinna width, height of left external nares, height of right external nares and the rima oris length were 17 +/- 1.3 cm, 90 +/- 16 g, 4.6 +/- 0.58 cm, 13 +/- 1.3 cm, 13 +/- 1.3 cm, 8.7 +/- 1.5 cm, 8.7 +/- 1.4 cm, 0.98 +/- 0.12 cm, 0.96 +/- 0.13 cm and 19.51 +/- 2.89 cm respectively, while the mean brain weight, mean brain length, cerebrum and cerebellum lengths, brain and cerebellar heights were 84 +/- 12 g, 6.9 +/- 1.5 cm, 4.9 +/- 1.7 cm, 2.2 +/- 1.0 cm, 5.2 +/- 0.88 cm and 3.0 +/- 1.1 cm respectively. There was a negative correlation between the weight of the animal and the height of the cerebellum, the length of cerebrum and length of the cerebellum and between the weight of the head and height of the cerebellum. A positive correlation was however observed between the length of brain and the weight of brain, and between the length of the cerebrum and weight of brain. The cerebral length was statistically longer (P < 0.01) in the males than the females. The data obtained from this study will provide added information in the field of comparative anatomy and porcine neuroanatomy research. PMID:21898972

    From February to March 2016 we found plerocercoids of Spirometra sp. in four wild boar hunted in Białowieża Primeval Forest, north-eastern Poland. Plerocercoids were located subcutaneously and in muscle tissue. A sequence of a nuclear 18S rRNA gene was used for genetic specification of the samples. The analyzed gene fragment showed 100% identity with the Spirometra erinacei sequence. Thus, the emerge of human sparganosis due to consumption of undercooked or smoked wild boar meat is likely in the areas where wild boar is an approved food source, especially in the absence of routine guidelines for vets. It has become a priority to inform the public about possibilities and consequences of this zoonosis. PMID:27523946

    Lectin,galactose-binding,soluble 1 (LGALS1) gene encodes galectin-1,an atypical secretory protein that plays an important role during myoblast proliferation and differentiation.In this study,the porcine LGALS1 gene was cloned and characterized from pig muscle.The predicted protein sequence shared a high identity with its mammalian counterparts.Reverse transcription-polymerase chain reaction revealed that porcine LGALS1 was expressed at 33 day post-coitus (dpc) and 65 dpc at a relatively high level,and then decreased to 90 dpc during fetal skeletal muscle development,suggesting that galectin-1 is a potent factor implicated in the formation of myofibers.LGALS1 was found widely expressed in all tissues and transient transfection indicated that galectin-1 locates both in cytoplasm and nucleus.Genomic sequences and analysis predicted a promoter region at approximately 1.279.1.529 kb,but dualluciferase reporter assay indicated that it has little promoter activity.

The pig is also a valuable biomedical model organism for human health. The pig's importance to human health and nutrition is reflected in the decision to sequence its genome (3X. As an animal species with its wild ancestors present in the world, the pig provides a unique opportunity for tracing mammalian evolutionary history and defining signatures of selection resulting from both domestication and natural selection. Completion of the pig genome sequencing project will have significant impacts on both agriculture and human health. Following the pig whole genome sequence drafts, along with large-scale polymorphism data, it will be possible to conduct genome sweeps using association mapping, and identify signatures of selection. Here, we provide a description of the pig genome sequencing project and perspectives on utilizing genomic technologies to exploit pig genome evolution and the molecular basis for phenotypic traits for improving pig production and health.

    Porcine cysticercosis is a serious zoonosis in resource-poor countries. Despite the evidence showing that the disease is endemic in the Punjab region of India, molecular characterisation of Taenia solium cysticercosis from naturally infected pigs has not been carried out. The authors examined a total of 519 pigs slaughtered in small slaughter shops (shops that sell meat from animals that are slaughtered on the premises as the customer waits) in the urban slums of Punjab state in northern India. The expected polymerase chain reaction products with molecular sizes of 286 bp, 420 bp, 1150 bp and 333 bp corresponding to the targeted large subunit ribosomal RNA (rRNA), cytochrome oxidase 1, internal transcribed spacer 1, and diagnostic antigen Ts14 genes, respectively, were amplified from the cysts collected from all 22 infected carcasses. The detection limits for the respective primers (except those targeting the Ts14 gene) were estimated. The analytical sensitivities of both the TBR and JB primers (targeting the rRNA and cytochrome oxidase genes, respectively) were found to be higher (10 pg) than that of the internal transcribed spacer 1 gene (1 ng) primers. Ten representative samples from cytochrome oxidase 1 gene amplified products were sequenced in both directions for phylogenetic analysis. Sequencing demonstrated that all cysticerci were of the Asian genotype of T. solium and not of the African/Latin American genotype or T. asiatica. The results confirm the presence of T. solium porcine cysticercosis in Punjab state and there is therefore an urgent need for science-based policies for prevention and control of this serious zoonosis.

    In Central Europe the wild boar population is permanently growing and consequently Cf foodborne infections. In this study serological and molecular detection of Toxoplasma gondii and Neospora caninum in wild boars was evaluated. Moreover, same samples were screened for the presence and genetic variability of tick-borne bacterium Anaplasma phagocytophilum. Blood samples collected from 113 wild boars from Southern Slovakia were examined for antibodies to T. gondii by indirect and to N. caninum by competitive ELISA. The presence of parasitic DNA in blood samples was determined by standard or real time PCR techniques. Antibodies against T. gondii and N. caninum were detected in 45 (39.8%) and 38 (33.6%) animals, respectively. Females were more frequently infected for both pathogens than males. The high seropositivity against both coccidia indicates a permanent occurrence of these pathogens in the studied locality. T. gondii DNA was confirmed in five seropositive boars (4.4%) and N. caninum in 23 blood samples (20.4%). Three out of 23 N. caninum PCR positive animals did not show seropositivity. Three out of 113 blood samples of wild boars were positive for A. phagocytophilum (2.7%). The obtained A. phagocytophilum sequences were 100% identical with GenBankTM isolates from Slovak dog (KC985242); German horse (JF893938) or wild boar (EF143810) and red deer (EF143808) from Poland. Coinfections of T. gondii with N. caninum and N. caninum with A. phagocytophilum were detected in single cases. Results suggest a potential zoonotic risk of toxoplasmosis transmission to humans and the spread of neosporosis to farm animals. PMID:27078648

    Full Text Available Abstract 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.

    Full Text Available In the present study we examined the brain of fetal, newborn, and adult pigs raised for meat production. The fresh and formalin-fixed weights of the brain have been recorded and used, together with body weight, to calculate the Encephalization Quotient (EQ. The weight of the cerebellum has been used to calculate the Cerebellar Quotient (CQ. The results have been discussed together with analogue data obtained in other terrestrial Cetartiodactyla (including the domestic bovine, sheep, goat, and camel, domesticated Carnivora, Proboscidata, and Primates. Our study, based on a relatively large experimental series, corrects former observations present in the literature based on smaller samples, and emphasizes that the domestic pig has a small brain relative to its body size (EQ = 0.38 for adults, possibly due to factors linked to the necessity of meat production and improved body weight. Comparison with other terrestrial Cetartiodactyla indicates a similar trend for all domesticated species.

    Sophie Rossi

    Full Text Available Constitutive humoral immunity (CHI is thought to be a first-line of protection against pathogens invading vertebrate hosts. However, clear evidence that CHI correlates with host fitness in natural conditions is still lacking. This study explores the relationship between CHI, measured using a haemagglutination-haemolysis assay (HAHL, and resistance to classical swine fever virus (CSFV among wild boar piglets. The individual dynamics of HAHL during piglet growth was analysed, using 423 serum samples from 92 piglets repeatedly captured in the absence of CSFV (in 2006 within two areas showing contrasting food availability. Natural antibody levels increased with age, but, in the youngest piglets antibody levels were higher in individuals from areas with the highest food availability. Complement activity depended on natural antibody levels and piglets' body condition. In the presence of CSFV (i.e., in 2005 within one area, serum samples from piglets that were repeatedly captured were used to assess whether piglet HAHL levels affected CSFV status at a later capture. The correlation between CHI and resistance to CSFV was tested using 79 HAHL measures from 23 piglets captured during a CSFV outbreak. Both natural antibodies and complement activity levels measured at a given time correlated negatively to the subsequent probability of becoming viremic. Finally, capture-mark-recapture models showed that piglets with medium/high average complement activity, independently of their age, were significantly less at risk of becoming viremic and more likely to develop a specific immune response than piglets with low complement activity. Additionally, piglets with high average complement activity showed the highest survival prospects. This study provides evidence linking CHI to individual fitness within a natural mammal population. The results also highlight the potential of HAHL assays to explore the dynamics and co-evolution between wildlife mammal hosts and blood-borne parasites interacting with the CHI.

    Full Text Available Three feral pig populations inhabiting contrasting environments along the north easterncoast of Australia have been investigated with respect to population structure, individual condition andreproduction. The population on Prince of Wales Island contains a large proportion of juvenile andsub-adult pigs but lacks pigs in the higher age classes. Individuals also breed at an earlier age thananimals of the mainland populations. Pig populations on Cape York Peninsula show a largerproportion of older animals and feral pigs living in rainforest habitats show a low proportion ofanimals in very young and very old age classes. Pigs from the lowland rainforest population are inbetter condition than those of the other populations for most of the year, reflecting the availability offood all year round in this environment. Differences in the population structure of the threepopulations are discussed with respect to fecundity and several mortality factors such as predation anddiseases/parasites.

    In Switzerland sarcoptic mange is frequent in free-ranging wild carnivores but until recent years no cases had been recorded in wild ungulates. Since 2010, cases have been observed in wild boar in the cantons of Solothurn, Tessin and Thurgau. Here, we report the detection of mange-like skin lesions in wild boars by photo-trapping and the post-mortem findings in 6 culled animals presenting different stages of the disease. Potential sources of infection include mangy red foxes, outdoor domestic pigs and wild boars from surrounding countries. Disease spread in the wild boar population may become relevant not only for wildlife but also for domestic pig health in the future if piggeries' biosecurity is insufficient to prevent interactions with wild boar.

    Full Text Available 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.

    The performance of a completely implantable peritoneal artificial pancreas (AP) has been demonstrated in principle in a live diabetic domestic pig. The device consists of a smart glucose-sensitive gel that forms a gateway to an insulin reservoir and is designed to both sense glucose and deliver insulin in the peritoneal cavity. It can be refilled with insulin via subcutaneous ports and surgery was developed to insert the AP. Diabetes was induced with streptozotocin (STZ), the device filled with insulin (Humulin(®) R U-500) in situ and the animal observed for several weeks, during which time there was normal access to food and water and several oral glucose challenges. Blood glucose (BG) levels were brought down from >30 mmol/L (540 mg/dL) to non-fasted values between 7 and 13 mmol/L (126-234 mg/dL) about five days after filling the device. Glucose challenge responses improved ultimately so that, starting at 10 mmol/L (180 mg/dL), the BG peak was 18 mmol/L (324 mg/dL) and fell to 7 mmol/L (126 mg/dL) after 30 min, contrasting with intravenous attempts. The reservoir solution was removed after 8 days of blood glucose levels during which they had been increasingly better controlled. A rapid return to diabetic BG levels (30 mmol/L) occurred only after a further 24 days implying some insulin had remained in the device after removal of the reservoir solution. Thus, the closed loop system appeared to have particular influence on the basal and bolus needs for the 8 days in which the reservoir solution was in place and substantial impact for a further 3 weeks. No additional insulin manual adjustment was given during this period. PMID:26691655

Esta espécie colonizou as carcaças de porcos do estágio enfisematoso à esqueletização. Adultos foram observados eventualmente predando larvas de moscas a partir do segundo dia de intervalo pós-morte e suas larvas foram observadas a partir do quinto dia se alimentando em áreas esqueletizadas, provavelmente limpando os ossos dos tecidos moles remanescentes. O comportamento predatório dos adultos nas larvas de dípteros mais velhas podem impactar suas populações e complicar estimativas de intervalo pós-morte, uma vez que estas são freqüentemente usadas para esta estimativa. Além disso, adultos e larvas têm potencial uso como indicadores de intervalo pós-morte (IPM porque o adulto pode colonizar carcaças do segundo dia em diante e as larvas do quinto dia em diante.

    The aim of this study was to examine the effects of litter size and parity on sibling competition, piglet survival, and weight gain. It was predicted that competition for teats would increase with increasing litter size, resulting in a higher mortality due to maternal infanticide (i.e., crushing) and starvation, thus keeping the number of surviving piglets constant. We predicted negative effects on weight gain with increasing litter size. Based on maternal investment theory, we also predicted that piglet mortality would be higher for litters born late in a sow's life and thus that the number of surviving piglets would be higher in early litters. As predicted, piglet mortality increased with increasing litter size both due to an increased proportion of crushed piglets, where most of them failed in the teat competition, and due to starvation caused by increased sibling competition, resulting in a constant number of survivors. Piglet weight at day 1 and growth until weaning also declined with increasing litter size. Sows in parity four had higher piglet mortality due to starvation, but the number of surviving piglets was not affected by parity. In conclusion, piglet mortality caused by maternal crushing of piglets, many of which had no teat success, and starvation caused by sibling competition, increased with increasing litter size for most sow parities. The constant number of surviving piglets at the time of weaning suggests that 10 to 11 piglets could be close to the upper limit that the domestic sow is capable of taking care of. PMID:21743767

  6. Social Complexification and Pig (Sus scrofa Husbandry in Ancient China: A Combined Geometric Morphometric and Isotopic Approach.

    Full Text Available Pigs have played a major role in the economic, social and symbolic systems of China since the Early Neolithic more than 8,000 years ago. However, the interaction between the history of pig domestication and transformations in Chinese society since then, have not been fully explored. In this paper, we investigated the co-evolution from the earliest farming communities through to the new political and economic models of state-like societies, up to the Chinese Empire, using 5,000 years of archaeological records from the Xiawanggang (XWG and Xinzhai (XZ sites (Henan Province. To trace the changes of pig populations against husbandry practices, we combined the geometric morphometric analysis of dental traits with a study of the stable carbon and nitrogen isotope ratios from bone collagen. The domestication process intensified during the Neolithic Yangshao, prompted by greater selective pressure and/or better herd control against wild introgression. After that, pig farming, in XWG, relied on local livestock and a gradual change of husbandry practices overtime. This was characterized by a gentle increase in millet foddering and animal protein intake, until a complete change over to household management during the Han dynasty. The only rupture in this steady trend of husbandry occurred during the Longshan period, with the appearance of small sized and idiosyncratic pigs with specific feeding practices (relying on millet and household scraps. From three exploratory hypothesis, we explored the possibility of anti-elite pig production in XWG during the Longshan period, as a means to resist incorporation into a new economic model promoting intensified domestic production. This exploratory hypothesis is the most suitable to our dataset; however, numerous areas need to be explored further in order to adequately document the role of pigs in the rise of China's complex societies.

  7. Feeding of wild boar (Sus scrofa L.) in the exclusion zone of the Chernobyl accident in the territory of Ukraine

    International Nuclear Information System (INIS)

    Investigations of seasonal feed choice of a wild boar have been carried out during a 3-year period on the basis of the stomach content. Results of the investigations are given. A list of forage plants and forage animals is presented. Seasonal intensity of their consumption is evaluated. Main plant assemblages of the exclusion zone of the Chernobyl accident are analyzed for their significance in the diet of a wild boar. Special attention is paid to the role of underground forage (35% of average annual forage), and to consumption of Oenotera biennis roots comprising 26% of average annual forage. Recent state of the forage base and of the wild boar population is estimated. An attempt to predict its dynamics for the nearest 10-15 years is made

    Full Text Available The aim of our project was to study the effect of streptozotocin (STZ—induced hyperglycemia on sciatic nerve morphology, blood plasma markers and immunohistochemical expression of RAGE (the Receptor for Advanced Glycation End-products, and its ligands—S100B and Carboxymethyl Lysine (CML-advanced glycation endproduct (AGE in the laboratory pig. Six months after STZ—injections, blood plasma measurements, morphometric analysis of sciatic nerve fiber density, immunofluorescent distribution of potential molecular neuropathy contributors, ELISA measurement of plasma AGE level and HPLC analysis of sciatic nerve levels of one of the pre-AGE and the glycolysis intermediate products—methyl-glyoxal (MG were performed. The results of our study revealed that STZ—injected animals displayed elevated levels of plasma glucose, gamma glutamyl transferase (GGT and triglycerides. The sciatic nerve of STZ-injected pigs revealed significantly lower numbers of small-diameter myelinated fibers, higher immunoreactivity for RAGE and S100B and increased levels of MG as compared to control animals. Our results correspond to clinical findings in human patients with hyperglycemia/diabetes-evoked peripheral neuropathy and suggest that the domestic pig may be a suitable large animal model for the study of mechanisms underlying hyperglycemia-induced neurological complications in the peripheral nerve and may serve as a relevant model for the pre-clinical assessment of candidate drugs in neuropathy.

  10. Impact of drive hunts on daytime resting site areas of wild boar family groups (Sus scrofa L.

    Full Text Available The population density of wild boar in Lower Saxony, Germany has increased enormously in the last decades. Therefore, it is crucial to reduce the density by hunting the wild boar, especially in zones of Classical Swine Fever disease (CSF. The drive hunt, which is an effective hunting method, forces wild boars to leave their daily resting sites. However, this hunting method increases the risk of animals spreading over a wider area, which leads to a greater risk of infecting other individuals with the CSF-virus.Behavioural data of nine radio-marked wild boar family groups (corresponding to ten observations and their habitat use was analysed by telemetry. Particular attention was given to the effects of drive hunting on the selection of daytime resting sites before and after a drive hunt. On average the daytime resting range size of the different groups covered 627 ha. The observation period lasted approximately eight weeks (four weeks before and after a drive hunt. The mean resting range area was 183 ha and it increased to 299 ha after the hunt. Six wild boar groups increased temporarily the size of their resting ranges after a hunt. Three of them moved up to 6 km outside their range. The groups left their forest stands and had to cross extensive coverless farmland. Four groups reduced their resting range size. On average, the family groups became active during the night after the drive hunts.

    This study presents the first molecular and serological evaluation of Echinococcus granulosus infections in wild boars in Iran. Twenty five wild boars were collected in south-western Iran, during authorized hunting program, from March to October 2013, necropsied and examined for E. granulosus infection. Furthermore, seroprevalence of cystic echinococcosis in hunted boars was evaluated by an ELISA system. A fertile hydatid cyst due to E. granulosus was detected in the lung of one of the animals. Genotype analysis of the isolate was determined by analyzing a mitochondrial gene, cytochrome C oxidase subunit 1 (co1). DNA was extracted from the cyst sample and polymerase chain reaction amplification and DNA sequencing of the specific region of the co1 gene was performed. Molecular evaluation confirmed the presence of a sheep strain, the G1 genotype, in the wild boar in south-western Iran. This is the first report of the presence of G1 genotype of E. granulosus in wild boar in Iran. Serological evaluation of hydatid cyst by antigen-B ELISA revealed E. granulosus antibodies in 5 (20%) of 25 wild boars. A statistically significant difference was observed between the prevalence of E. granulosus antibodies and gender while the difference between the seroprevalence of E. granulosus and age was insignificant. Findings of this study might have important implications for the prevention and control of cystic echinococcosis. PMID:26878625

Epinephrine concentration was determined by ELISA twice: one week after taking samples and a month after repeated freezing at -80°C. It was higher in relation to the reference value of domestic pigs and human (109.45 pg/ml in A and 119.54 pg/ml in B group. Repeated freezing and re-analysis after a month were resulted in lower concentrations of epinephrine (12% in young and 11.17% in adult animal, but without statistical significance (P>0.05. Biochemical analysis results’ show increased glucose and triglycerides concentrations compared to the reference values, while other indicators were observed within or slightly increased referring to the normal range. The correlation between glucose and epinephrine was not determined.

    Full Text Available This study aimed to determine the optimal location for BUKLOD-UNLAD Multi-purpose Cooperative (BUKLOD’s CERDO Real Meat products distribution centers and to identify the market condition once the optimal location was identified. The said cooperative from Dagatan, a barangay of Taysan, Batangas, Philippines identified the need to create distribution center specifically in District IV of Batangas Province due to the growing demand for their real meat products in the area. Hence to address this need, a study to identify for its optimal location was requested by BUKLOD from the researchers. First, interviews with the management and members of the cooperative were done by the researchers to identify the requirements in establishing a distribution center. In the same way, consultations with the 7 municipalities of District IV were piloted to inform them accordingly about the said project. Moreover the researchers also referred to the Comprehensive Land Used Plan 2012-2022 of each municipality provided by the Provincial Planning and Development Office along with geographical maps gathered from the Provincial Engineers Office to acquire specific data on locations of the involved municipalities. Through various facility planning tools such as Factor Rating Method, Analytical Hierarchy Process and Center of Gravity, the researchers identified Rosario, Batangas as the best location for establishing the distribution center. After a market study was conducted, the researchers further proved the viability of establishing BUKLOD’s CERDO’s products’ distribution center in the area.

    Large red scorpionfish, Scorpaena scrofa, is a prevalent, important and highly valued commercial species throughout the rocky coastal areas of the Mediterranean Sea. Despite this, there is a surprising scarcity of biological and ecological information for this species. As artisanal fisheries have a very long tradition in the whole Mediterranean, a considerable impact of continuous fishing pressure is expected on this valuable rockfish. To elucidate some biological parameters that indicate the status of S. scrofa in the Adriatic Sea and to show which consequences high fishery effort may have on its age, growth and reproduction, sampling was carried out in the middle Adriatic using trammel nets. Temporal trends in body size/weight of S. scrofa were also assessed using long-term data including specimens caught from 1960 to 2010. Temporal trends of S. scrofa in the middle Adriatic indicated significant decreases of 19% in length and 43% in total weight over time. In contrast, official landings for the last five years showed an increase of 13%. However, this increasing trend most likely reflects the continuous change in national policies for reporting the catches. Both catch data and landings statistics showed peak in catch per unit effort during summer which coincides with spawning period of S. scrofa. Length at first sexual maturity was observed at 29.0 cm for females and 24.9 cm for males. All specimens larger than 32 cm were mature. Age analysis revealed 15 age classes with a 25 year old female as the oldest specimen. However, age classes 3+ and 4+ were predominant in the total catch. The growth rate is relatively high during the first four years of life and afterwards it considerably slows down, with females growing at slightly slower rate and attaining slightly larger sizes than males. Given the identified biological implications that confirm our assumptions of inherent vulnerabilities and negative effects arising from continued artisanal fisheries practice

  14. Magnetic characteristics of ferromagnetic stainless steels, SUS 403, SUS 410J1, TAF and SUS 405

    International Nuclear Information System (INIS)

    Ferromagnetic stainless steels have been used in magnetic and electro-magnetic devices which are exposed to severe environments such as an incore of nuclear reactor. Wide use of these materials is naturally due to their ferromagnetism, and also due to their excellent properties in corrosion, radiation and heat resistances. Easy machining process at a low cost and good availability in the market are counted for them as another advantage. However, their magnetic properties are not well established in a standard form as refered in handbooks, because they are originally developed as a structure material. This situation, the lack of sufficient data, leads us to study the magnetic properties of the martensitic stainless steels, SUS 403, SUS 410J1 and TAF, and the ferritic stainless steel, SUS 405, in connection with the development of incore instruments. The magnetic properties were measured for many specimens after various heat treatments such as quenching and tempering, low temperature annealing and full annealing. Temperature dependence of magnetic properties was measured with an electric furnace. Magnetic properties measured in this study were of initial magnetization, dc hysteresis, ac permeability and inverse magnetostriction, and Curie point as well. The martensitic stainless steels show somewhat semi-hard characteristics (Hc; 5 - 15 oersteds) and the ferritic stainless steel is rather soft (Hc; 2 - 5 oersteds). The Curie points range from 720 to 750 deg C. The saturation magnetization is about 15000 gausses. The large inverse magnetostriction is observed in SUS 403 and SUS 405, and this may be utilized in acoustic and sonic application as well as in force and pressure measurements. Because the magnetic properties depend on the heat treatments, the optimum condition of heat treatment may be chosen so as to satisfy requirements to the magnetic characteristics. (J.P.N.)

    Full Text Available Dentro de los problemas infecciosos más graves que afectan a la porcicultura intensiva en todo el mundo se encuentran los trastornos respiratorios, los cuales producen efectos adversos sobre la ganancia de peso, la eficiencia alimenticia y la mortalidad. Las enfermedades respiratorias en el cerdo son muy comunes y distribuidas en todos los países y climas donde existe producción porcina intensiva con valores de prevalencia que pueden llegar hasta el 100%. Existen múltiples micoorganismos que pueden afectar al aparato respiratorio del cerdo pero hoy día se acepta que todo proceso respiratorio es el resultado de una compleja interacción en la que pueden verse involucrados gran número de agentes por lo que habitualmente se ha hablado de un "Complejo Respiratorio Porcino" para referirnos a este tipo de problemas pulmonares de etiología múltiple, no obstante, actualmente se maneja el término de “Suis-Ide Diseases” para aludir a la complejidad de las etiologías y cuadros que intervienen en el tracto respiratorio del cerdo. Con relación a los agentes de naturaleza infecciosa se relacionan a los virus, las bacterias y los micoplasmas. En tal sentido algunos autores han señalado al virus del Síndrome Respiratorio y Reproductivo Porcino (PRRS y la Neumonía Enzoótica, cuyo agente etiológico principal es Mycoplasma hyopneumoniae, como los principales objetivos a tener en cuenta a la hora de plantear un programa vacunal. En el presente trabajo tiene como objetivo tratar algunos elementos que ayudaran a ampliar el conocimiento sobre Mycoplasma hyopneumoniae y su relación con los procesos respiratorios del cerdo a partir de la experiencia cubana en esta temática.

    Full Text Available The origin and distribution of the sciatic nerve was studied in 31 pig fetuses from the lineage Pen Ar Lan, being 22 males and 9 females, after being fixed in a 10% formaldehyde aqueous solution. In these animals, the lumbar vertebrae ranged from 5 to 7, with a predominance of 6, something which contributed to variations in the origin of this nerve. The sciatic nerve originated in 80.64% of the antimeres from the ventral branch of the fifth lumbar spinal nerve (L5; in 96.77 % of L6; in 6.45% of L7; in 100% of S1; and in 64.51% of S2. The composition of this nerve took place in 45.16% of the animals due to the union of L5, L6, S1 and S2; in 32.25% of L5, L6 and S1; in 12.90% of L6, S1 and S2; in 6.45% of L6, L7 and S1; and in 3.22% L5, S1 and S2. There was symmetry in the origin of the sciatic nerve in all specimens under study. This nerve sent branches to the superficial gluteal, semitendinosus, semimembranosus and biceps femoris muscles in all specimens, and, in a lesser frequency, to the twins, quadratus femoris, adductors, as well as the middle, accessory, and deep gluteal muscles. In 74.19% of the sample, a branch communicating to the pudendal nerve was observed.

    Sometimes, commercial products obtained from wild animals are sold as if they were from domestic animals and vice versa. At this point of the productive chain, legal control of possible wildlife products is difficult. Common in the commerce of northern Argentina, skins of two wild species, the carpincho and the collared peccary, look very similar to each other and to those of the domestic pig; it is extremely difficult to differentiate them after they have been tanned. Because there was no an adequate methodology to discriminate between leather of these three species, we developed a new methodology of DNA extraction from skin and leather. This new method involves digesting a leather sample using proteinase K, followed by precipitation of proteins with 5 M NaCl, cleaning with absolute isopropanol and DNA precipitation with 70% ethanol. DNA is hydrated in Tris-EDTA buffer. This protocol provided good-quality DNA suitable for analysis with molecular markers. This new protocol has potential for use in identifying leather products of these species using molecular markers based on RAPDs. PMID:22535403

    This study investigated whether individual behavioural characteristics of piglets and stress induced by experience with humans can influence learning performance. After weaning, piglets received a chronic experience with humans to modulate their emotional state: rough (ROU), gentle (GEN), or minimal (MIN) experience. Simultaneously, they were trained on a discrimination task. Afterward, their behaviour during challenge tests was assessed. The first learning step of the task involved associating a positive sound cue with a response (approach a trough) and success of piglets depended mostly on motivation to seek for reward. Although the experience with humans did not have direct effect, the degree of fear of handler, measured based on their reactivity to a human approach test, was related to motivation to seek rewards and learning speed of this first step in stressed ROU piglets, but not in MIN and GEN piglets. In contrast, the second learning step was more cognitively challenging, since it involved discrimination learning, including negative cues during which piglets had to learn to avoid the trough. Locomotion activity, measured during an open-field test, was associated with performance of the discrimination learning. To conclude, fearfulness towards humans and locomotion activity are linked with learning performance in relation to task complexity, highlighting the necessity to take into account these factors in animal research and management.

    The wild boar population has increased enormously in all of Europe over the last decades and caused problems like crop damage, transmission of diseases, and vehicle accidents. Therefore, it is necessary to investigate the underlying causes of this increase in order to be able to manage populations effectively. The purpose of this study was to analyse how environmental (food and climate) and physiological factors (maternal weight and age) as well as hunting and population density influence the litter size of wild boar populations in Northern Germany. The mean litter size in the studied population for the whole period was 6.6 (range 1–12), which is one of the highest in all of Europe. Litter size was positively influenced by maternal body weight, higher mast yield of oak as well as higher temperature in combination with higher precipitation in summer. Only higher temperature or only higher precipitation in summer however had a negative effect on litter size production. Probably,weather and food conditions act via maternal bodyweight on the litter size variation in wild boar. Hunting as well a s population density did not affect the litter size variation in this study which might indicate that wild boar population did not reach carrying capacity yet. PMID:26437356

    The relation between intestinal parasite prevalence in wild boars and red foxes and the sanitary condition of the soil in recreational estates were determined. The analysis was made based on 36 samples of boar faeces and 22 samples of fox faeces, collected in their habitat as well as 60 samples of soil from two recreational areas. Two methods were used for faecal samples--flotation and direct faecal smear; and flotation in NaNO3 for soil samples examination. Zoonotic nematode eggs were recovered from 25.5% of boar faecal samples; they were Ascaris suum (22.2%) and Trichuris suis (5.6%). Other parasites found were: Metastrongylus sp. (69.4%), Oesophagostomum sp., Strongyloides sp. (36.6%) and Physocephalus sp. (8.6%) as well as coccidia (69.4%). In fox faeces, zoonotic nematode eggs were recovered from 31.8% of samples, and they were Toxocara canis (27.2%) and Ancylostoma caninum (18.2%). Tapeworm eggs were found in 36.4% of samples including Taenia sp. (22.7%). The presence of Uncinaria stenocephala (45.5%), Capillaria sp. (36.4%), Trichuris vulpis (4.5%) and coccidia (40.1%) was also detected. It was shown that both, flotation and faecal smear, as mutually complementary should be used for higher rate of detection of parasites in faeces. No eggs of zoonotic helminths in soil from recreational areas were found despite these areas were accessible to wild animals and pets. This could be explained by characteristics of the soil (loose sand soil) as well as by behaviour of the parasite hosts in the examined areas. PMID:21174955

    Normal growth is the expression of the genetic potential to growth which is neither abnormally constrained nor promoted by internal or external factors. Restricted fetal growth is common in human pregnancy and is associated with increased perinatal morbidity and mortality. Because of ethical restrictions, pathogenetical studies are necessarily dependent on appropriate animal models. In the studies presented, evidence will be provided that the naturally occurring distribution of body weight in newborn piglets, obtained from n = 512 newborn piglets (about 12 hours old) in 50 consecutive deliveries in the breed cohort of the mixed German domestic breed - "Deutsches Land-/Edelschwein" gives an appropriate sampling for providing a statistically reliable basis with which to determine different degrees of fetal growth for further pathophysiological studies intended. A strong inverse correlation (r = -0.66, p correlation (r = -0.64, p correlation between body weights and various organ weights was found (values of the correlation coefficient amounted to between 0.45 and 0.98; p 0.68-1.33). Skeleton and heart exhibited similar ranges of weight variation (0.35-1.81 and 0.38-2.00 of the means) to body weight (0.38-1.77 of the means). This was also expressed in the regression analysis, because the slope values were 0.99 and 0.97 respectively. The hormonal glands investigated, the kidneys, and the abdominal parenchymal organs exhibited the largest ranges of weight variation. Moreover, regression analysis gives evidence that the weight restriction was more pronounced than expected concerning respective body weight. This is indicated by slope values > 1 in almost all of those organs. Plasma concentration of IGF-1 showed an inverse correlation with body weight (r = -0.42; p more than 2.5 times in IUGR newborn (fig 5 A, p < 0.05). This investigation provides information on the naturally occurring body weight distribution of one-day-old piglets, which was obviously a result of epigenetic factors. Gravimetrical estimation showed clearly that body weight variety is most probably caused by alterations of placental functioning. Severe alterations resulted in asymmetrical growth retardation, which was proved by a significantly increased brain to liver ratio in animals with a body weight < 10th centile. Thus, evidence is provided that naturally occurring asymmetrical intrauterine growth restricted newborn piglets can be identified simply by body weight measurement, so that convenient conditions are given for pathogenetically motivated studies on intrauterine compromised newborns.

    Full Text Available The parallel growth of urban areas and wild boar populations in recent years has increased the presence of this species around cities and in suburban areas, often leading to conflict with local people. In the Collserola Natural Park, situated within the metropolitan area of Barcelona, wild boar have become habituated to humans and urban settings because of direct feeding by local residents. Their attraction to these areas due to an abundance of anthropogenic food sources is especially strong during the warmer summer season when foraging conditions are poorer in their natural woodland habitat; the number of captures of habituated wild boar in peri–urban areas is significantly correlated with mean monthly temperatures. Habituated boar are primarily matriarchal groups, whereas adult and sub–adult (>1 year males are significantly less represented than in non–habituated boars. In Collserola, habituated sub–adult and adult females are significantly heavier than their non–habituated counterparts and these weight differences increase with age; in the > 3 year–old age class they may be 35% heavier. Conflicts generated by the presence of wild boar in peri–urban areas are complex, and the responses by authorities are similarly diverse and often exacerbated by ambivalent public attitudes, both towards wild boar presence and applied mitigation measures. By 2010, at least 44 cities in 15 countries had reported problems of some kind relating to the presence of wild boar or feral pigs.

    Oral mass vaccination (OMV) is considered as an efficient strategy for controlling classical swine fever (CSF) in wild boar. After the completion of vaccination, the presence of antibodies in 6-12 month-old hunted wild boars was expected to reflect a recent CSF circulation. Nevertheless, antibodies could also correspond to the long-lasting of maternal antibodies. This paper relates an experience of surveillance which lasted 4 years after the completion of OMV in a formerly vaccinated area, in north-eastern France (2010-2014). First, we conducted a retrospective analysis of the serological data collected in 6-12 month-old hunted wild boars from 2010 up to 2013, using a spatial Bayesian model accounting for hunting data autocorrelation and heterogeneity. At the level of the whole area, seroprevalence in juvenile boars decreased from 28% in 2010-2011 down to 1% in 2012-2013, but remained locally high (above 5%). The model revealed the existence of one particular seroprevalence hot-spot where a longitudinal survey of marked animals was conducted in 2013-2014, for deciphering the origin of antibodies. Eleven out of 107 captured piglets were seropositive when 3-4 months-old, but their antibody titres progressively decreased until 6-7 months of age. These results suggest piglets were carrying maternal antibodies, few of them carrying maternal antibodies lasting until the hunting season. Our study shows that OMV may generate confusion in the CSF surveillance several years after the completion of vaccination. We recommend using quantitative serological tools, hunting data modelling and capture approaches for better interpreting serological results after vaccination completion. Surveillance perspectives are further discussed. PMID:26810218

    The vocal expression of emotion is likely driven by shared physiological principles among species. However, which acoustic features promote decoding of emotional state and how the decoding is affected by their listener's psychology remain poorly understood. Here we tested how acoustic features of piglet vocalizations interact with psychological profiles of human listeners to affect judgments of emotional content of heterospecific vocalizations. We played back 48 piglet call sequences recorded in four different contexts (castration, isolation, reunion, nursing) to 60 listeners. Listeners judged the emotional intensity and valence of the recordings and were further asked to attribute a context of emission from four proposed contexts. Furthermore, listeners completed a series of questionnaires assessing their personality (NEO-FFI personality inventory), empathy [Interpersonal Reactivity Index (IRI)] and attitudes to animals (Animal Attitudes Scale). None of the listeners' psychological traits affected the judgments. On the contrary, acoustic properties of recordings had a substantial effect on ratings. Recordings were rated as more intense with increasing pitch (mean fundamental frequency) and increasing proportion of vocalized sound within each stimulus recording and more negative with increasing pitch and increasing duration of the calls within the recording. More complex acoustic properties (jitter, harmonic-to-noise ratio, and presence of subharmonics) did not seem to affect the judgments. The probability of correct context recognition correlated positively with the assessed emotion intensity for castration and reunion calls, and negatively for nursing calls. In conclusion, listeners judged emotions from pig calls using simple acoustic properties and the perceived emotional intensity might guide the identification of the context. PMID:25798794

    Michal Zalecki

    Full Text Available Gastric ulcerations in the region of antrum pylori represent a serious medical problem in humans and animals. Such localization of ulcers can influence the intrinsic descending nerve supply to the pyloric sphincter. The pyloric function is precisely regulated by intrinsic and extrinsic nerves. Impaired neural regulation could result in pyloric sphincter dysfunction and gastric emptying malfunction. The aim of the study was to determine the effect of gastric antral ulcerations on the density and distribution of intramural gastric descending neurons supplying the pyloric sphincter in pigs.The experiment was performed on 2 groups of pigs: healthy gilts (n=6 and gilts with experimentally induced peptic ulcers in the region of antrum pylori (n=6. Gastric neurons supplying pyloric sphincter were labeled using the retrograde neuronal tracing technique (20μl of Fast Blue tracer injected into the pyloric sphincter muscle. After a week survival period the animals were sacrificed and the stomachs were collected. Then, the stomach wall was cross-cut into 0.5cm thick sections taken in specified intervals (section I - 1.5cm; section II - 3.5cm; section III - 5.5cm; section IV - 7.5cm starting from the sphincter. Consecutive microscopic slices prepared from each section were analyzed under fluorescent microscope to count traced neurons. Obtained data were statistically analyzed. The total number of FB-positive perikarya observed within all studied sections significantly decreased from 903.3 ± 130.7 in control to 243.8 ± 67.3 in experimental animals. In healthy pigs 76.1 ± 6.7% of labeled neurons were observed within the section I, 23.53 ± 6.5% in section II and only occasional cells in section III. In experimental animals, as many as 93.8 ± 2.1% of labeled cells were observed within the section I and only 6.2 ± 2.2% in section II, while section III was devoid of such neurons. There were no traced perikarya in section IV observed in both groups of pigs.Obtained results revealed for the first time significant impact of antral ulcerations on intramural descending nerve pathways supplying the pyloric sphincter in pigs, animals of increasing value in biomedical research and great economic importance.

    Full Text Available The faunal assemblage from the 9(th-8(th 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 8(th 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.

    Full Text Available Gills arches of the freshwater fish Prochilodus scrofa Steindachner, 1881 (Lt= 8.0-12.4cm were removed to be analyzed in a scanning electron microscope. The morphology of the superficial structures of the gill filaments and pharyngeal region of the gills arches was discussed and related to their functional aspects. A great quantity of mucous secretory cells and of microridges, along with the pavement cell surface of the primary lamellae and branchial pharyngeal region, indicate the existence of a protection strategy of the respiratory lamellae. The chloride cells are abundant, specially on the distal portion of the primary lamellae, and bring out the osmo regulatory capacity of this species. This fish seems not to be a filtering one according to: its short and simple gill rakers; presence of several taste buds turned towards the mouth opening; evidence of spines on the external side of the arches and an abundant secretion of mucous in the pharyngeal region. This species probably selects the food to be swallowed through its chemical receptors and retains it with the help of spines and mucous secretion this way protecting the gills filaments against the rubbing of particles over them.

    Full Text Available El clenbuterol frecuentemente se ha utilizado de forma ilícita en el engorde del ganado, suponiendo ello un riesgo para la salud pública. La actual normativa prohíbe por tanto su uso en la cría del ganado. En este estudio se utilizaron 14 cerdos distribuidos al azar en dos grupos de estudio (n=7, uno control, y otro expuesto a 1 mg/kg de clenbuterol durante tres meses. Se utilizó el músculo longissimus lumbaris para la determinación de la concentración de clenbuterol, así como para la evaluación de los parámetros inmunohistoquímicos y el análisis estructural y ultraestructural de las fibras. El estudio de los distintos biomarcadores histopatológicos e inmunohistoquímicos de las fibras musculares, tras la exposición de los animales al clenbuterol, indicó la presencia de hipertrofia muscular, miofibrolisis y degeneración zenkeriana, observada tanto por microscopía óptica como electrónica. Mediante la técnica miosina ATP-asa se identificó un tipo de fibra denominada alterada en el grupo tratado que no apareció en el grupo control. Por tanto, se comprueba que el músculo longissimus lumbaris resulta una buena matriz para la investigación de la exposición a largo plazo a este compuesto en cerdos.

    Full Text Available This report concerns an outbreak of postweaning multisystemic wasting syndrome in wild boars from commercial herds in Rio Grande do Sul, Brazil. The main clinical signs were progressive wasting, respiratory distress, diarrhea, and ocular discharges. Enhanced lymph nodes and spleens, ascites, hydrothorax, and non collapsed lungs were the principal gross lesions. Varying degrees of lymphohistiocytic infiltrates in lymph nodes, spleen, and intestines were the most significant microscopic changes. Although a total of 26 animals had showed clinical and pathological findings consistent with the disease, only in 11 of them it was possible to confirm a PMWS diagnosis through the association of specific lesions in lymphoid tissues with the presence of the viral antigen detected by immunohistochemistry. These findings were similar to those reported in the swine disease.Descreve-se a ocorrência da síndrome multissistêmica do definhamento suíno em javalis de dois rebanhos comerciais no estado do Rio Grande do Sul. Os principais sinais observados foram definhamento progressivo, tosse, espirros, diarréia e descarga ocular. Linfonodos e baços aumentados, ascite, hidrotórax e pulmões não colapsados foram os principais achados macroscópicos. Infiltrados linfo-histiocitários de graus variáveis em linfonodos, baços e intestinos foram as lesões microscópicas mais relevantes. Embora 26 animais tenham apresentado achados clínicos e patológicos compatíveis com a enfermidade, apenas em 11 desses foi possível confirmar o diagnóstico através da associação de lesões histológicas específicas nos tecidos linfóides com a presença do antígeno viral, detectado pela técnica de imunoistoquímica. Tanto os achados clínicos como patológicos foram semelhantes aos descritos na doença suína.

    Full Text Available A partir de una reseña sobre el papel del intervencionismo estatal en la conducción de la economía y de la pugna con el neoliberalismo, se hace una revisión de los modelos económicos aplicados a lo largo del siglo y se muestran sus rasgos principales, sus problemas y sus paradojas. A partir de alfí, se examina lo sucedido en América Latina, para dar cuenta de las particularidades del caso colombiano, cuyo modelo en esta década muestra una distancia grande del modelo neoliberal, mientras sus problemas lo acercan a los dilemas y sin salidas del intervencionismo, en un contexto que requeriría otras fórmulas para hacer posible la paz. Frente a ello, se examinan las posiciones y propuestas de los economistas, vistas bajo la aguda polarización entre intervencionismo y neoliberalismo, pero en circunstancias críticas que alejan los logros en torno a la modernización, la estabilidad de precios, la sólida fundamentación macroeconómica y la democratización política.

    Full Text Available El presente trabajo se realizó con el propósito de considerar a las técnicas inmunohistoquímicas como método de diagnóstico seguro y rápido para la identificación de antígenos fimbriales de E. coli en intestino delgado de cerdos lactantes con cuadro diarreico. Se realizó aislamiento microbiológico e inmunohistoquímica en duodeno, yeyuno e íleon de 50 cerdos lactantes infectados naturalmente. E. coli sola (34% así como asociada (24% a otros microorganismos fue el agente etiológico mas frecuentemente diagnosticado en cerdos lactantes con diarrea, seguido de Salmonella sp., Rotavirus y Campylobacter sp. Mediante IHQ se identificó antígenos fimbriales en 10 cerdos con aislamiento de E. coli, en 1 con Salmonella sp. y en 5 sin diagnóstico etiológico. El antígeno fimbrial más frecuentemente encontrado fue F41 en 8 cerdos entre 1 y 35 días de edad, seguido de la asociación de F4-F41 en 5 animales de 15 a 28 días y, finalmente, F4 en 3 cerdos entre 8 y 35 días. E. coli F4 fue identificado en los tres segmentos intestinales, mientras que E. coli F41 colonizó principalmente íleon y yeyuno. Los resultados de la presente investigación confirman la importancia de E. coli en los cuadros de diarrea en cerdos lactantes, así como la efectividad de las técnicas IHQ para la identificación de antígenos fimbriales en cortes de intestino embebidos en parafina.

    Full Text Available Objetivos. Caracterizar bacterias ácido lácticas probióticas aisladas del intestino grueso de cerdos adultos como posible alternativa al uso de antibióticos. Materiales y métodos. Se incluyeron muestras de intestino grueso de 20 cerdos adultos, para el aislamiento de bacterias lácticas (BAL. La caracterización de los parámetros bioquímicos-fisiológicos de las BAL contemplo la evaluación del pH del fermento, determinación de ácidos orgánicos por HPLC y detección de isómeros de ácido láctico. Los procedimientos microbiológicos evaluaron la capacidad de inhibición del crecimiento de patógenos y la actividad antagónica del probiótico vs antibiótico con su interacción competitiva. Se utilizaron pruebas API CHL 50 para la identificación de las BAL que se complementaron con la producción de gas, actividad de catalasa y viabilidad a diferentes concentraciones de sales biliares y temperaturas. Resultados. El plan de análisis permitió seleccionar dos aislados que se identificaron como: Lactobacillus plantarum 1 H1 y Lb. plantarum 1 H2. Las pruebas microbiológicas evidenciaron que las BAL seleccionadas inhibieron principalmente los enteropatógenos: Escherichia coli, Salmonella typhimurium y Clostridium perfringens. Las pruebas bioquímicas fueron compatibles con el género Lactobacillus, mostrando el siguiente perfil: Catalasa negativas; no productoras de gas; productoras de isómeros DL; resistentes a sales biliares y pH óptimo de crecimiento 3.5 a 38oC. Conclusiones. Los dos aislados de Lactobacillus plantarum 1 reunieron las características para el uso potencial como probióticos. Se recomienda su uso como complemento de terapias con antibióticos y en la elaboración de inóculos para aplicación en raciones alimenticias de lechones destetos, sin embargo, estudios complementarios se requieren para evaluar el efecto directo del probiótico como sustituto del uso de antibióticos in vivo.

    Full Text Available We give the results obtained for the determination of trans fatty acids in subcutaneous and intramuscular fats from different pork samples, using gas chromatography. Values obtained are low and similar in both kind of fats, with a mean value of 0.6% of C18:1 trans. A clear influence of animal feeding is detected due to the significant differences of this isomer content between samples from different origin. Also, correlations have been observed between C18:1 t. content and saturated, mono, polinsaturated fatty acids and fat intramuscular contents.

    Se presentan los resultados obtenidos en la determinación de ácidos grasos trans en una serie de muestras de tejidos subcutáneo y muscular, procedentes de canales de cerdo, mediante cromatografía en fase gaseosa. Ambos tipos de grasas presentan valores similares y relativamente bajos, con un valor medio del 0.6% de 018:1 t. Se detecta una marcada influencia de la alimentación, puesta de manifiesto por las diferencias significativas obtenidas para los contenidos de C18:1 trans, en función del origen de las muestras. Igualmente, se recogen las correlaciones obtenidas entre los contenidos de C18:1 t. y los de ácidos grasos saturados, monoinsaturados y poliinsaturados, así como con el contenido graso intramuscular.

    The Bawean warty pig (Sus blouchi) is an endemic pig species confined to the 192 km2 large island of Bawean in the Java Sea, Indonesia. Due to a lack of quantitative ecological research, understanding of natural history and conservation requirements have so far been based solely on anecdotal information from interviews with local people and study of captive and museum specimens. In this study we provide the first assessment of population and habitat preferences for S. blouchi by using camera trapping. From the 4th of November 2014 to January 8th 2015, we placed camera traps at 100 locations in the forested protected areas on Bawean. In 690.31 camera days (16567.45 hours) we captured 92 independent videos showing S. blouchi. Variation in S. blouchi trapping rates with cumulative trap effort stabilized after 500 camera days. An important outcome is that, in contrast to the suggestion of previous assessments, only S. blouchi was detected and no S. scrofa was found, which excludes hybridization threats. We fitted a Random Encounter Model, which does not require the identification of individual animals, to our camera-trapping data and estimated 172–377 individuals to be present on the island. Activity patterns and habitat data indicate that S. blouchi is mainly nocturnal and prefers community forests and areas near forest borders. Next to this, we found a positive relationship between S. blouchi occupancy, distance to nearest border, litter depth and tree density in the highest ranking occupancy models. Although these relationships proved non-significant based on model averaging, their presence in the top ranking models suggests that these covariables do play a role in predicting S. blouchi occurrence on Bawean. The estimated amount of sites occupied reached 58%. Based on our results, especially the estimation of the population size and area of occupancy, we determine that the species is Endangered according to the IUCN/SSC Red List criteria. PMID:27049756

    Full Text Available Background: Acute respiratory distress syndrome (ARDS is a fatal complication of severe sepsis. Due to its higher molecular weight, the use of colloids in fluid resuscitation may be associated with fewer cases of ARDS compared to crystalloids. Extravascular lung water (EVLW elevation and levels of interleukin-8 (IL-8 and vascular cell adhesion molecule-1 (VCAM-1 have been studied as indicators playing a role in the pathogenesis of ARDS. The aim of the study was to determine the effects of colloid or crystalloid on the incidence of ARDS, elevation of EVLW, and levels of IL-8 and VCAM-1, in swine models with severe sepsis.Methods: This was a randomized trial conducted at the Laboratory of Experimental Surgery, School of Veterinary Medicine, IPB, using 22 healthy swine models with a body weight of 8 to 12 kg. Subjects were randomly allocated to receive either colloid or crystalloid fluid resuscitation. After administration of endotoxin, clinical signs of ARDS, EVLW, IL-8, and VCAM-1 were monitored during sepsis, severe sepsis, and one- and three hours after fluid resuscitation. Analysis of data using the Wilcoxon test , Kolmogorov-Smirnov test, Mann-Whitney test, unpaired t test.Results: Mild ARDS was more prevalent in the colloid group, while moderate ARDS was more frequent in the crystalloid group. EVLW elevation was lower in the colloid compared to the crystalloid group. There was no significant difference in IL-8 and VCAM-1 levels between the two groups.Conclusion: The use of colloids in fluid resuscitation does not decrease the probability of ARDS events compared to crystalloids. Compared to crystalloids, colloids are associated with a lower increase in EVLWI, but not with IL-8 or VCAM-1 levels.

    人和野猪的冲突已经成为日益关注的问题。2010年6-10月,在黑龙江省尚志市青云林场利用走访和问卷调查对野猪危害进行了研究,并通过散布东北虎粪便、放置东北虎图像、播放东北虎声音的方法对野猪危害进行了防治并与当地居民防治野猪危害的措施进行了比较。结果如下:(1)野猪危害多在夏初至秋末,主要危害玉米和西葫芦,受危害的农田多是林缘地和林间地。(2)把野猪第2次进入农田与第1次进入农田的间隔天数作为防治措施的有效性评估指标,研究发现利用东北虎粪便、图像、声音防治野猪危害的有效期分别是3.00±0.58d、1.33±0.33d、5.25±0.63d。(3)林场84.09%的居民会采取防治措施,防治措施有效期一般是3-7d。(4)利用东北虎粪便和图像防治野猪危害的效果与林场大多数居民采取的防治措施效果相比差异不显著(P〉0.05)。利用声音防治危害的效果只与利用塑料绳围栏(P=0.029)和干扰物(P=0.029)的防治效果相比差异显著。利用东北虎粪便、图像和声音防治野猪危害效果不理想可能和这个地区东北虎消失时间比较长有关。%In recent years, the frequency of conflicts between wild boar and humans has increased. From June to October 2010, we surveyed crop damage caused by wild boar in Qingyun forest in Shangzhi County, Heilongjiang Province using questionnaires and field investigations. Wild boar damage took place almost from early summer to late autumn and the main crops damaged by wild boar were corn and squash, mainly in fields located near the forest edge or in the forest. We conducted field experiments to evaluate the effectiveness of various measures intended to deter wild boar from damaging crops. Measures includ-ed placement of tiger faeces at the perimeter of crop areas, playing of recorded tiger vocalizations, placement of life - sized photos of tiger faces at crop perimeters, and placement of life-sized models of Siberian tigers at crop perimeters. We defined an index for the effectiveness of these measures as the interval between the first entry of boar to a given field ( the date when the preventive measure was installed) and the next entry of boar to the same field. The mean number of effective days when using faeces, image models and vocalizations of Siberian tiger were 3.00±0. 58 days, 1.33±0. 33 days and 5.25 ±0. 63 days, re-spectively. Most of the local people in Qingyun ( 84. 09% ) implemented other measures whose effectiveness lasted from 3 to 7 days. The mean number of effective days was not significantly different between faeces and image models of the tiger and the traditional prevention measures implemented by the inost of the local residents ( P 〉 0. 05 ) . While the mean effective days showed significant difference between sounds of tiger and plastic fence ( P = 0. 029 ) and disruptors ( P = 0. 029 ) implemented by the forest residents. This might be explained in part by the fact that the native Siberian tiger disappeared many years earlier from Qingyun forest farm, Heilongjiang.

These scenarios were evaluated on their economic consequences, environmental impacts and consumer acceptance. the results were then used as the input for a second round of stakeholder workshops, which aimed at developing short-term strategies and implementation plans. This Research Note reviews the SusHouse approach and its results. It ends with suggestions for further steps to be taken. A SusHouse CD-ROM is available, containing all final project reports as well as a scenario presentation in the form of images and short texts. 22 refs

    Full Text Available Se evaluó por medio de la radiografía digital y la densitometría, la influencia de un dispositivo de rotación para el corte en el proceso de curación del hueso después de osteotomías en mandíbulas de cerdos, a tiempos controlados. Se realizaron dos secciones transversales en la base de la mandíbula derecha, una con una alta velocidad de rotación y otra por la acción de baja velocidad, ambos con el líquido de irrigación. Tras los tiempos preestablecidos, los animales fueron sacrificados y sus mandíbulas retiradas para los estudios radiográficos y de densitometría radiológica con los sistemas digitales Cromox, Digora y ODR. En los períodos iniciales (7 y 28 días el equivalente a la densitometría en milímetro de aluminio y la media de niveles de gris fueron más altos en la región de osteotomías hechas con alta rotación, y en los períodos finales (60 y 90 días las mayores densitometrías fueron para osteotomías hechas con baja velocidad, lo que indica una mejor cicatrización final del hueso cuando se hace uso de la baja velocidad. El análisis cualitativo del proceso de reparación fue realizado por el ODR, lo que permitió la recopilación de imágenes digitales en color y en tres dimensiones, para la comparación del espesor del hueso con una cuña de aluminio, indicando que en los 28 días de curación del hueso, ya estaba evidente la completa reparación.The influence of the type of rotary cutting instrument on bone repair after osteotomy in swine jaw, was evaluated using digital and densitometric radiographic examinations, at controlled times. Two cross-sectional dissections were made through the base of the right jaw, one using a high speed rotary instrument and the other using low speed, both with liquid cooling. After established periods the animals were sacrificed and their jaws removed for direct and indirect digital radiographic and densitometric studies using the CROMOX, DIGORA and ODR systems.

Se identificaron 6 tipos de especies de parásitos gastrointestinales: Macrachantorinchus hirudinaceu, Oesophagustomun spp, Áscaris suum, Trichuris suis e Hyostrongylus rubidus, siendo este ultimo el de mayor prevalencia. Se determinó la prevalencia de PGI en heces de cerdos en dos grupos de edades. Se identificaron los helmintos Ascaris suum, Hyostrongylus, rubidus, Strongiloides ransomi, Oesophagostomun spp, y Trichuris suis. Los protozoos encontrados fueron Isospora suis y Eimeria sp. Con una mayor frecuencia se encontró Ascaris suum (42.86% e Hyostrongylus (39.80%, en el grupo mayor de seis meses, en el grupos menor de seis meses los más frecuentes eran Áscaris suum (48.98% y Trichuris (45.92%. La intensidad de infestación de H. rubidus fue significativamente más alto en grupo de cerdos mayores de seis y T. suis e Isospora suis tuvieron diferencia significativa en el grupo menor de seis meses.

    Full Text Available In 2005 the Argentinian writer Eduardo Sacheri published The Question in Their Eyes (La pregunta de sus ojos.  The novel narrates on a double level, both fictional and temporal, the decision of a retired prosecutor to come to terms with a case of rape and murder which had taken place years earlier: his life had been shattered by the consequences of that tragedy, and writing about it would be a way to start living again.  The director Juan José Campanella - widely famous for having directed episodes of the television series Law & Order, but especially as the director of successful films such as El hijo de la novia - decided to adapt the novel and involved Sacheri in the project: the close collaboration between writer and director produced a bold screenplay that adds to the noir thriller a more romantic dimension.  Disproving the commonplace of the writer jealous of his work, they wrote together a new version which retains certain elements of the original text, but also introduces a number of relevant changes to the structure, characters and ending of the novel.  The Secret in Their Eyes  (El secreto de sus ojos, shot in 2008, was released the following year and in 2010 won the Academy Award for best foreign language film.

Mil setecientas diecinueve personas asistentes a partidos de fútbol organizados por la Liga de Fútbol Profesional contestaron cuestionarios sobre sus valores, motivaciones y relación con el fútbol. Los resultados muestranque los entusiastas son los aficionados más motivados y comprometidos con el fútbol al mismo tiempo que participan significativamente más de valores relacionados con el conservadurismo y la autopromoción que las otras tres categorías (espectadores, aficionados presenciales y aficionados virtuales. La clasificaciónpropuesta en base al tipo de contacto con el fútbol permite conceptualizar el fútbol como algo más que lo que ocurre en los estadios y abre las puertas a intervencionesdesde lo positivo para promover el fair play y la deportividad en los aficionados.

    2008-06-01

    Full Text Available The Greek philosophy developed three types of philosophical schools. The first one, represented by the Milesians, the Eleatics and partly the Aristotle’s Lyceum, understands the philosophical activity as a set of projects of investigation, not necessarily lacking of pragmatic interest, moved by desire to explain the phenomena. Next to their activities of investigation, many of these philosophers maintain a political activity within the framework of their own cities. The second type, represented by the Pythagoreans and the Academy of Plato, aims to reach the union between knowledge and political power. This proposal finds its better synthesis in the ideal of philosopher king. At the hellenistic period, the goal of philosophical schools would be to offer the cultivated and instructed man a particular way of life.La filosofía griega desarrolló tres tipos de escuelas filosóficas. El primero, representado por los milesios, los eleáticos y, en parte, el Liceo de Aristóteles, entiende la actividad filosófica como un conjunto de proyectos de investigación, no necesariamente carentes de interés pragmático, movidos por el deseo de explicar los fenómenos. Junto a sus actividades de investigación, muchos de estos filósofos mantienen una actividad política en el marco de las instituciones de sus propias ciudades. El segundo tipo, representado por los pitagóricos y la Academia platónica, se propone alcanzar la unión entre el saber y el poder. Esta propuesta halla su mejor síntesis en el ideal del filósofo rey. Finalmente, en la época helenística, las escuelas filosóficas se proponen sobre todo ofrecer un ideal de vida al hombre culto e instruido de su tiempo.

    Full Text Available The pork meat industry in Chile exhibits significant rates of production growth, with a decreasing trend in the wholesale market price and growing levels of concentration of the supply in a reduced number of companies. The structural element that sustains concentration and expansion of the production is the presence of increasing returns to scale in the production process. This investigation had the objective to verify the presence of economies of scale in this industry. Using a Cobb-Douglas cost function and the assumption of maximization of the benefits of the company in imperfect competition markets, an econometric model was estimated, that allowed considering indirectly the coefficients of the function of underlying production. One was that for the period 1975-2005, the industry presented increasing returns to scale, with an elasticity product-scale of 1.23 and economies of scale, with elasticity cost-production of 0.81. It was concluded that this industry shows conditions to increase its advantage in costs and of expanding its competitiveness in international markets.La industria de la carne de cerdo en Chile exhibe tasas significativas de crecimiento de la producción, acompañada por una tendencia decreciente en el precio a nivel de mercado mayorista, y por niveles crecientes de concentración de la oferta en un número reducido de empresas. El elemento estructural que sustenta la concentración y expansión de la producción es la presencia de rendimientos a escala crecientes en el proceso de producción. Esta investigación tuvo por objetivo verificar la presencia de economías de escala en esta industria. Utilizando una función de costos Cobb-Douglas y el supuesto de maximización de beneficios en una empresa en competencia imperfecta, se estimó un modelo econométrico que permitió estimar indirectamente los coeficientes de la función de producción subyacente. Se encontró que para el período 1975-2005, la industria present

    Full Text Available Body fluid ionic content of fishes varies with ambient. Variations in the plasmatic ionic concentration have also been related with sex or maturation cycle, once that reproduction modifies metabolic processes. In fishes, the gallbladder is an important osmoregulatory organ. So, the present work has been focused on the relation of plasmatic and biliar electrolytes with sex and maturation cycle, of the teleost fish Prochilodus scrofa at the resting and mature stages of gonadal cycle. The animals (28 males and 30 females were collected at Cachoeira de Emas (Pirassununga, São Paulo and they were fasted for three days before the experiments. Deteminations of Na+, K+, Mg++, and Ca++ were made by spectophotometry and Cl- by microtitulation. Comparisons of ionic content between sex and maturation cycle were assessed using analysis of variance and Student-Newman-Keuls test. In this work it was seen that in males and females at resting and mature stages, there are no difference at ionic plasmatic content. K+ contents were higher in the bile of mature males than in resting ones. Mg++ biliar contents were higher in resting males than in resting and mature males. Na+, Ca++ e Cl- contents have no difference. Na+, K+, Ca++ and Mg++ contents were higher in the bile than in the plasma. Cl- content was higher in plasma than in bile. Variations related with proteic synthesis, and another metabolic processes during cycle, may be the reason of variations in the biliar ionic content.

Se formularon matrices con registros biológicos y socioeconómicos obtenidos entre el 2009 y 2010 en temporadas de alto registro turístico, obteniendo 17 variables en 20 playas analizadas. La evaluación se efectuó con el modelo semiparamétrico del tipo KSIM con dos escenarios: uno sin control/restricción en el desarrollo costero y otro con las mismas características pero con decremento en demanda turística por baja calidad ambiental. Los resultados mostraron un marcado descenso en playas arenosas y costas rocosas. En el modelo se hace referencia a la importancia de los procesos de las playas y su interrelación con los factores biológicos, sociales y económicos más importantes, proporcionando una visión integral de todas las variables. Se recomienda incrementar el modelo dándole mayor envergadura, integrando a las instituciones que influyen en el control de las acciones en estas playas, lo que dará un mejor referente y monitoreo a corto, mediano y largo plazo.

  17. Corrosion of SUS304 stainless steel in oxalic acid solution

    International Nuclear Information System (INIS)

    The corrosion rate of oxidized and unoxidized SUS304 stainless steel was measured in 0.1M oxalic acid at 80degC under the potentiostatically polarized conditions. The dissolved amounts of Fe, Cr and Ni were determined by atomic absorption analysis after 166 min of polarization as a function of the potential. The corrosion potential and the sweep potentiostatic polarization curve were also measured in the same solution. The unoxidized specimen was severely attacked at the cathodic potential between -200 and -700 mV vs Ag-AgCl. Similar cathodic corrosion was also found, but with a decreased dissolution rate, for oxidized specimens. Since the corrosion potential of the alloy situated nearly at the boundary of active passive transition, both specimens frequently suffered localized attack due to insufficient passivation during spontaneous immersion. The dissolution rate of the surface oxide was slightly effected by the electrode potential within the active and the passive regions. Therefore, weakly anodic polarization is desirable for the dual purposes of the effective dissolution of surface oxide and the protection of substrate alloy surface. (author)

    Microstructural damage and nano hardness of the industrial grade stainless steel (SUS-316) have been studied under proton (H{sup +}) implanted condition applying different doses at room temperature. The implantation scheme such as proton energy, fluence, irradiation time, and penetration depth in the target materials were estimated by Monte Carlo Simulation Code SRIM-2008. In the simulation, the parameters were chosen in such a way that the damage density (displacement per atom or dpa) would be uniform up to certain depth from the surface. X-ray diffraction study of the annealed samples prior to the proton implantation showed the austenitic fcc structure and no significant change was observed after proton implantation in it. Microstructural observation made by Scanning Transmission Electron Microscopy (STEM) revealed that 1 dpa of proton-irradiation induced the structural damage extended up to 1 μm depth from the surface. The nano hardness study showed that the hardness level of the irradiated samples increased monotonically with the irradiation doses. Proton dose of 1 dpa caused 65% increment of hardness level on average in case of uniformly irradiated samples. It was realized that the increment of hardness was a consequence of microstructural damages caused by the formation of interstitial dislocation loops in the sample matrix keeping the lattice structure unaffected.

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

    International Nuclear Information System (INIS)

    PNC provided SUS 304 plate to be irradiated in FFTF at about 4000C to a target fluence of 5 x 1021 n/cm2 (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

    Full Text Available AIMS: To analyse the influence of lean pork (P and veal (V consumption on the lipid profile of healthy subjects within the framework of a healthy diet comprising low levels of total fat (TF, saturated fatty acids (SFA and cholesterol. DESIGN: Double-crossover, randomized and controlled trial SUBJECTS: 44 healthy individuals (22 male and 22 female, recruited voluntarily from the University Complutense of Madrid. The weight and lipid profiles of these volunteers were normal and their dietary patterns were typical for people in our area. INTERVENTIONS: The study comprised 4 phases: stabilisation phase (5 weeks, the participants followed their normal diet; second phase (6 weeks, half of the subjects, were randomised to lean pork or veal consumption, 150 g per day, for their main meal of the day; washout period (5 weeks and final phase, which was the second phase of intervention (6 weeks. During the intervention stages, only the main meal of the day was taken in the Hospital. The rest of the subjects' diets consisted of different fortnightly menus designed in accordance with the recommendations of the Spanish Society of Arteriosclerosis (SEA. RESULTS: After both stages of intervention had been completed, there was a mean reduction of 5.5% in lowdensity lipoprotein cholesterol. However, after each intervention there were no significant differences between those who had consumed P, 2.62 (0.55 mmol/L and those who had consumed V, 2.71 (0.47 mmol/L. No differences were observed in any of the other parameters between those who had consumed P and those who had consumed V. CONCLUSIONS: Lean pork and veal produces similar effects on the lipid profiles of healthy subjects. Its consumption, as part of the saturated fat and cholesterolcontrolled diet, could therefore be included in food guidelines, both for normal and therapeutic diets.OBJETIVO: Analizar la influencia del consumo de carne magra de cerdo (P y de ternera (V en el perfil lipídico de sujetos sanos

    Sucrose synthase (Sus) is a key enzyme in plant sucrose metabolism.In cotton,Sus (EC 2.4.1.13) is the main enzyme that degrades sucrose imported into cotton fibers from the phloem of the seed coat.This study demonstrated that the genomes of Gossypium arboreum L.,G.raimondii Ulbr.,and G.hirsutum L.,contained 8,8,and 15 Sus genes,respectively.Their structural organizations,phylogenetic relationships,and expression profiles were characterized.Comparisons of genomic and coding sequences identified multiple introns,the number and positions of which were highly conserved between diploid and allotetraploid cotton species.Most of the phylogenetic clades contained sequences from all three species,suggesting that the Sus genes of tetraploid G.hirsutum derived from those of its diploid ancestors.One Sus group (Sus I) underwent expansion during cotton evolution.Expression analyses indicated that most Sus genes were differentially expressed in various tissues and had development-dependent expression profiles in cotton fiber cells.Members of the same orthologous group had very similar expression patterns in all three species.These results provide new insights into the evolution of the cotton Sus gene family,and insight into its members' physiological functions during fiber growth and development.

    Full Text Available El presente artículo analiza la crisis estructural del capitalismo provocada por el estallido de la burbuja especulativa inmobiliaria en EEUU en 2007 y sus repercusiones. El presente fenómeno es el desenlace de una serie de procesos desencadenados en respuesta a la crisis de sobreacumulación del capital de los años setenta que generó, por un lado, las condiciones para el dominio del capital financiero y, por otro lado, una nueva frontera de acumulación del capital en el Este asiático, sobre todo en China. La crisis cuestiona la centralidad de la economía norteamericana, lo que no significa necesariamente el desplazamiento del centro hegemónico del capitalismo hacia Asia. Lo que aquí defendemos, es la idea de que nos dirigimos hacia un mundo multipolar. This article analyzes the structural crisis of capitalism that began when the speculative home mortgage bubble burst in the United States in 2007, and the repercussions of that phenomenon. The current crisis is the outcome of a series of processes unleashed as a result of the crisis of overaccumulation of capital in the 1970s, which generated, on the one hand, the conditions for financial capital’s dominance and, on the other, a new frontier for the accumulation of capital in East Asia, especially in China. The crisis calls into question the centrality of the North American economy, but that does not necessarily mean the shift of capitalism’s hegemonic center to Asia. Here we will argue that we are headed toward a multipolar world.

    Full Text Available La violencia intrafamiliar constituye una de las formas más frecuentes de violencia encontradas tanto a nivel nacional como internacional y dentro de estas el maltrato infantil presenta cifras alarmantes, y es el objeto de nuestra revisión. Los efectos de este problema repercuten notablemente en aquellos que sobreviven, ya que las consecuencias a largo plazo del maltrato infantil son más perjudiciales para lasvíctimas y sus familias, y más costoso para la sociedad, que las lesiones agudas inmediatas que puedan producir. Las consecuencias a largo plazo para estos niños varían desde efectos nocivos en su desarrollo hasta trastornos psicológicos, psiquiátricos y orgánicos. Es importante resaltar que aún con muy buenas intervenciones no todas tienen el éxito esperado si no se hacen de manera correcta. Esindispensable contar con estrategias de prevención que incluyan personal bien entrenado, una supervisión adecuada, los recursos necesarios, y un tiempo mínimo óptimo para enfrentar el problema y obtener los mejores resultados. ______________________________________________________________________Domestic violence is one of the most common forms of violence found both domestically and internationally. Within these, child abuse has alarming figures. This is the subject of this review. The effects of this problem significantly impact on those who survive; their long-term consequences are most severe and expensive for victimized child and his/her family than associated primary physical injuries. Thelong-term consequences for these children range from adverse effects on its psycholigical development to psychological, psychiatric organic disoders. It is important to note that good speeches are not enough to achieve success if any intervention are not done correctly. All prevention strategies include well-trained staff, appropriate supervision, resources, and a optimal time for addressing this problem to get the best results.

  6. ViSUS: Visualization Streams for Ultimate Scalability

    2005-02-14

    In this project we developed a suite of progressive visualization algorithms and a data-streaming infrastructure that enable interactive exploration of scientific datasets of unprecedented size. The methodology aims to globally optimize the data flow in a pipeline of processing modules. Each module reads a multi-resolution representation of the input while producing a multi-resolution representation of the output. The use of multi-resolution representations provides the necessary flexibility to trade speed for accuracy in the visualization process. Maximum coherency and minimum delay in the data-flow is achieved by extensive use of progressive algorithms that continuously map local geometric updates of the input stream into immediate updates of the output stream. We implemented a prototype software infrastructure that demonstrated the flexibility and scalability of this approach by allowing large data visualization on single desktop computers, on PC clusters, and on heterogeneous computing resources distributed over a wide area network. When processing terabytes of scientific data, we have achieved an effective increase in visualization performance of several orders of magnitude in two major settings: (i) interactive visualization on desktop workstations of large datasets that cannot be stored locally; (ii) real-time monitoring of a large scientific simulation with negligible impact on the computing resources available. The ViSUS streaming infrastructure enabled the real-time execution and visualization of the two LLNL simulation codes (Miranda and Raptor) run at Supercomputing 2004 on Blue Gene/L at its presentation as the fastest supercomputer in the world. In addition to SC04, we have run live demonstrations at the IEEE VIS conference and at invited talks at the DOE MICS office, DOE computer graphics forum, UC Riverside, and the University of Maryland. In all cases we have shown the capability to stream and visualize interactively data stored remotely at the San

    Ugá, Maria Alicia Domínguez; Santos, Isabela Soares

    2006-08-01

    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

  1. Antibacterial properties, corrosion resistance and mechanical properties of Cu-modified SUS 304 stainless steel

    International Nuclear Information System (INIS)

    This investigation studies the effects of Cu content and ageing treatment on the microstructural, mechanical, corrosion and antibacterial properties of SUS 304 austenitic stainless steel. Cu was added respectively to SUS 304 stainless steels in proportions of 1.5, 2.5, 3.5, 4.5 and 5.5 wt.%. A vacuum arc remelting furnace was used to remelt SUS 304 stainless steel with various added Cu contents. These ingot alloys underwent hot rolling and various heat treatments, and were then cut into test specimens. A series of microstructural investigation, tensile tests, corrosion tests and antibacterial tests were conducted to study the properties of Cu-containing SUS 304 austenitic stainless steel. Microstructural observations reveal that the amount of retained δ-ferrite in the as-cast SUS 304 steel decreases as the Cu content increases. After hot rolling, the retained δ-ferrite disappears and α'-martensite forms in the austenitic matrix. The results of the tensile tests reveal that the ultimate tensile strength (UTS) declines as the Cu content increases below 2.5 wt.%. However, the ultimate tensile strength increases with the Cu content above 2.5 wt.%. X-ray diffraction analysis reveals that adding Cu suppresses the formation of strain-induced martensite (α'-martensite). The corrosion test indicates that the pitting potential declines as the Cu content in SUS 304 steels increases. The results of the antibacterial test reveal that adding a proper amount of Cu (such as 2 wt.%) gives SUS 304 stainless steel an excellent antibacterial property

    Highlights: • The microstructure of F82H/SUS316L dissimilar joint can be divided into four regions. • In the case without beam position shift, hardness of WM cannot be reduced by PWHT. • The fiber laser welding would be applicable for constructing the dissimilar joint. -- Abstract: As one of the high beam quality heat sources, 4 kW fiber laser was applied for joining between reduced activation ferritic/martensitic steel, F82H and SUS316L austenitic stainless steel, and the microstructural analyses and Vickers hardness measurements were carried out before and after post-weld heat treatment (PWHT). The microstructure of joint can be divided into four regions which are base metal of F82H, heat affected zone (HAZ) in F82H, weld metal (WM) and base metal of SUS316L. Also, it is revealed that the high-power fiber laser can be employed for constructing butt joint between F82H and SUS316L by applying PWHT and shifting the laser beam position to SUS316L, where the distance between the contact face and beam should be set as a range from radius to diameter of laser beam.

  5. An evaluation of designed Start-up System (SUS) for once-through steam generators

    International Nuclear Information System (INIS)

    Highlights: • Four SUS solutions are established to help reactors complete the start-up process. • Solutions C and D lead to superior behaved than Solutions A and B. • Solution C is fit for propulsion reactors and Solution D for nuclear power reactors. - Abstract: In this paper, we report on research that has been carried out both on the comparison and evaluation of four designed Start-up Systems (SUSs), which are proposed to improve reliability and economy during the reactor start-up process. Firstly, four SUS solutions are established to satisfy demands and detailed descriptions are introduced. Then, four reactor systems, which include SUS, are modeled by the estimate code JTopmeret. Furthermore besides, the JTopmeret code is validated for the once-through steam generators (OTSG). Finally, the behaviors of SUS and the steady and transient performance of OTSG are investigated. The results show that the designed SUS can successfully improve the economy and the OTSG operational safety. Suggestion is made in this paper to apply Solution C in propulsion-purposed reactors, and Solution D in nuclear power reactors

  6. Microstructure and tensile properties of friction welded SUS 304HCu austenitic stainless steel tubes

    International Nuclear Information System (INIS)

    Austenitic stainless steels are used in superheater/reheater tubing for their oxidation resistance and fireside corrosion resistance, in addition to their creep strength. The addition of 3 wt. % Cu to SUS 304HCu austenitic stainless steel to reduce the corrosion, has found to increase the creep performance in temperature range of 650°–750 °C. The addition of Cu to steels can have adverse effects on the mechanical properties of the fusion welded joints. During fusion welding, Cu can form low temperature eutectic phases that preferentially segregate to the grain boundaries and embrittle the alloy. There is a need for a better welding procedure/technique to fabricate this alloy. Friction welding is a solid state welding process which nullifies the adverse effects of low temperature eutectics segregation. Hence, in this investigation an attempt has been made to study the microstructural and tensile properties of the friction welded SUS 304HCu austenitic stainless steel tube joints fabricated using optimized parameters. -- Highlights: • Friction welding of SUS 304HCu tubes is reported. • Microstructures of friction welded SUS 304HCu tubes were reported. • Fracture surface of the tensile samples is characterized using SEM. • XRD analysis of the SUS 304HCu tube is reported

  9. A Study on the Creep Rupture Life of SUS 304 Stainless Steel Subjected to Hot Corrosion

    International Nuclear Information System (INIS)

    In order to predict the creep life of SUS 304 stainless steel being used as boiler superheater tubes under hot corrosion and creep environment, the creep tests were carried out at the temperature range of 630 to 750 .deg. C in static air for the specimens with or without coating of double layer corrosives according to the new hot corrosion test method. Finally, the equation for creep life prediction of SUS 304 stainless steel under hot corrosion condition was derived by method extrapolating creep rupture data. From the investigations of the creep rupture properties, it was also clarified that the creep life of SUS 304 stainless steel subjected to hot corrosion is chiefly determined by the aggressive intergranular penetration of sulfides and tube wall thinning, and that the creep rupture life is remarkably shortened at temperature near the melting point of the corrosive products

    Full Text Available Sucrose transport is the central system for the allocation of carbon resources in vascular plants. Sucrose synthase, which reversibly catalyzes sucrose synthesis and cleavage, represents a key enzyme in the control of the flow of carbon into starch biosynthesis. In the present study the genomic identification and characterization of the Sus2-2A and Sus2-2B genes coding for sucrose synthase in durum wheat (cultivars Ciccio and Svevo is reported. The genes were analyzed for their expression in different tissues and at different seed maturation stages, in four tetraploid wheat genotypes (Svevo, Ciccio, Primadur and 5-BIL42. The activity of the encoded proteins was evaluated by specific activity assays on endosperm extracts and their structure established by modelling approaches. The combined results of SUS2 expression and activity levels were then considered in the light of their possible involvement in starch yield.

    The surface modification for SUS316L stainless steel was carried out by electroplating Rh, ion beam assisted deposition Ta2O5 and sol-gel-derived TiO2. In Tyrodes stimulated body fluid, the surface modified samples were investigated with electrochemical techniques. The results indicate that the electrochemical stability and dissolution are improved significantly after surface modification. Moreover, as to ion beam assisted deposition Ta2O5 and sol-gel-derived TiO2 film, the metals d orbit electron holes filled up by the oxygen electrons make against the adsorption of hydrogen. Thus the cathode process, which is controlled by the hydrogen reduction, is held back. X-ray diffraction analysis of SUS316L stainless steel after surface modification reveal that each method forms the uniform and compact film on SUS316L stainless steel. These films prevent the dissolving of elements and improve passivation property of the SUS316L stainless steel.

    Structural materials used in radiation environments require radiation tolerance and sufficient mechanical properties in the controlled state. In order to offer SUS316L austenitic stainless steel with the assumed requirements, nanostructured SUS316L with TiC addition of 2% (SUS316L-2TiC) that is capable of exhibiting enhanced tensile ductility and flow strength sufficient for structural applications was fabricated by advanced powder metallurgical methods. The methods include MA (Mechanical Alloying), HIP (Hot Isostatic Pressing), GSMM (Grain boundary Sliding Microstructural Modification) for ductility enhancement, cold rolling at temperatures below Md (the temperature where the martensite phase occurs by plastic deformation) for phase transformation from austenite to martensite and heat treatment for reverse transformation from martensite to austenite. It is shown that the developed SUS316L-2TiC exhibits ultrafine grains with sizes of 90-270 nm, accompanied by TiC precipitates with 20-50 nm in grain interior and 70-110 nm at grain boundaries, yield strengths of 1850 to 900 MPa, tensile strengths of 1920 to 1100 MPa and uniform elongations of 0.6-21%, respectively, depending on the heat treatment temperature after rolling at -196 °C.

  5. Development of manufacturing process of PNC-FMS wrapper tube with SUS316 short joint

    International Nuclear Information System (INIS)

    When a ferritic-martensitic stainless steel (PNC-FMS) wrapper tube having far greater swelling resistance against neutron irradiation is applied in the JOYO or MONJU reactor, it becomes necessary to weld it with SUS316 austenitic stainless steel (entrance nozzle and handling head). Such welding between PNC-FMS and SUS316 causes the delta (δ) ferrite formation at heat-affected zone, which leads to significant toughness degradation. In addition, bending of wrapper tube caused by their differential thermal expansion should be straightened. For preventing those problems, manufacturing process of the complex wrapper tube was developed. This process involves TIG-welding with SUS316 short pipe joints in 50mm length to both ends of a PNC-FMS round tube, and then performing the drawing and normalizing and tempering. Normalizing induces complete disappearance of the δ ferrite in the course of wrapper tube manufacturing. The mechanical properties of PNC-FMS/SUS316 welded zone were confirmed to be equivalent to those of the base metal even after thermal aging. (author)

    Full Text Available The 2002 Brazilian Curricular Lines established a new curriculum for Pharmacy Programs, including amplified information about the Unified Health System (SUS. Following this, some Colleges have implemented a Rural Internship (RI discipline, as a way to promote: a adequate information on the SUS, and b students' interaction with pharmaceutical assistance. In this study we analyzed the perceptions of students enrolled in the Rural Internship program of the undergraduate Pharmacy Program at the Federal University of Minas Gerais. Eight students participated in this study and their perceptions and ideas were obtained by focus groups, both before and after the RI. This information was analyzed by content analysis. The students had a fragmented, distorted view on assistance, before as well as after taking the RI. Nevertheless, the RI provided students with a view of the professional realities and difficulties routinely faced by pharmacists in the public health system. The RI course of the Pharmacy Programs was viewed as an opportunity to improve the professional work within the SUS.As Diretrizes Curriculares de 2002 implantaram um novo currículo para o Curso de Farmácia, trazendo como propósito a aprendizagem para o Sistema Único de Saúde (SUS.

    In this study, the full-length cDNA of porcine liver-type fatty acid binding protein gene (L-FABP) was obtained by the rapid amplification of cDNA ends (RACE). The nucleotide sequence and the predicted protein sequence share a high sequence identity with their mammalian counterparts. Semi-quantitative RT-PCR revealed that porcine L-FABP gene is expressed in all twelve tissues studied, but a transcript is more abundant in liver and small intestine than in other tissues. The part genomic DNA of the porcine L-FABP gene was amplified by PCR. The coding region of the pig L-FABP gene is organized in four exons and spans an approximate 2.62 kb genomic region. Comparative sequencing of four pig breeds revealed a C→T single nucleotide polymorphism (SNP) within exon 2. The allele and genotype frequencies differed significantly between indigenous Chinese Zang, Dahe,and Yanan pigs with higher frequencies of allele C and genotype CC and Yorkshire pigs with higher frequencies of allele T and genotype TT (P < 0.01). The association analysis suggested that the C→T polymorphism was associated with intramuscular fat content, indicating that the SNP is a potential molecular marker for intramuscular fat content.%FABPs属于脂结合蛋白超家族成员,是一类分子量较小而对脂肪酸有高亲和力的蛋白质,广泛存在于脊椎动物和非脊椎动物的细胞质中.FABPs担当细胞内脂肪酸的运输任务,它们与脂肪酸结合将其运输到脂肪酸氧化的位置、脂肪酸脂化成甘油三醋或磷脂的位置,或者进入细胞核内发挥其可能的调控功能.因此FABPs对脂类代谢具有重要的调控作用.本研究把L-FABP基因作为影响猪肌内脂肪含量的候选基因.为此,利用cDNA末端快速扩增(RACE)和PCR技术,克隆到猪肝脏型脂肪酸结合蛋白基因(L-FABP)的全长cDNA序列(GenBank登录号:AY960623)和部分基因组序列(GenBank登录号:DQ182323).猪L-FABP基因的cDNA序列全长518 bp,该序列包括起始密码子TGA和38 bp的5'末端非编码区(5'URT),终止密码子TAG和99 bp的3'末端非编码区(3'URT),在3'URT结构区域中包含polyA加尾信号序列AATAAA.猪L-FABP基因与其他FABPs基因一样,也由4个外显子(67 bp、173 bp、93 bp和51 bp)和3个内含子组成,内含子1和3的大小是1 679bp和565 bp,没有获得内含子2的序列,外显子和内含子剪接处符合GT/AG规律.应用Clustal W/X程序对猪L-FABP与其他物种的L-FABP进行多重序列比对,发现猪L-FABP与人、大鼠、鸡的L-FABP的相似性分别为89.8%、81.9%和72.4%.亲水性分析表明,猪L-FABP也是一个潜在的跨膜蛋白,在氨基酸残基57-65之间有一个明显的跨膜α螺旋.应用半定量RT-PCR分析发现,猪L-FABP在猪体组织中广泛存在,但在肝脏和小肠组织中表达量最为丰富.分析还发现,所克隆得到的编码区核苷酸序列与已知猪L-FABP基因的编码区核苷酸序列存在一定的变异,分别是外显子2中T→C(116位)、C→T(231位)、C→A(236位)和A→C(258位),演绎成氨基酸在Leu74Met存在差异.为进一步证实这些突变位点在猪群中真实存在,利用PCR-SSCP检测方法对4个猪种(藏猪、大河猪、雅南猪和约克夏)的157头个体的外显子2全序列进行SNP位点多态性片段的基因型分型,结果发现一个C→T的单核苷酸多态,等位基因频率在中国地方猪种(藏猪、大河猪、雅南猪)与国外约克夏猪种间存在极显著的差异(P<0.01).连锁分析发现,基因型CC的肌内脂肪含量(4.86±0.22%)显著的高于基因型CT(4.16±0.23%)和TT(4.05±0.27%)的肌内脂肪含量(P<0.05).因此,推测L-FABP基因可能是影响猪肌内脂肪含量的主效基因或与主效基因紧密连锁的标记基因,并且能够在分子标记辅助选择中用于对猪肌内脂肪含量的遗传改良.

    Using cDNA of Landrace pig brain as the template, the full-length cDNAs of SOCS-1, SOCS-3. and SOCS-4 genes were cloned. Moreover, a pseudo-SOCS-3 gene was cloned using Landrace genom-ic DNA as template. SOCS-1 cDNA encodes a protein precursor of 220 amino acids, which shares high amino acid sequence identity with that of human (94%), rat (91%), mouse (91%), cattle (94%). SOCS-3 cDNA (690bp) encodes a protein precursor of 229 amino acids, which shares high amino acid sequence identity (> 94%) with that of mammals. The full-length cDNA of SOCS-4 encodes a protein precursor of 441 amino acids which shares high amino acid sequence identity with that of human (97%) , rat (89%) and mouse (86%). Further structural analyses indicate that pig SOCS-1, SOCS-3 and SOCS-4 contain an SH2 domain and a C-terminal SOCS box domain; SOCS-4 contains a large amino-terminus of 285 amino acids with no identifiable protein-interaction motifs. Using RT-PCR assay, the mRNA expression of SOCS-1, SOCS-3, and SOCS4 genes were also examined in adult pig tissues. The results showed that they were widely expressed in all of the tissues examined.%本文以长白猪(Landrace)大脑cDNA为模板,克隆得到长白猪细胞因子抑制因子SOCS-3基因,并首次克隆得到长白猪SOCS-1和SOCS-4基因.此外,还利用长白猪基因组DNA为模板克隆得到SOCS-3假基因(pseudo-SOCS-3).序列分析显示:长白猪SOCS-1基因cDNA编码220个氨基酸的前体蛋白,与人、小鼠、大鼠和牛的氨基酸序列一致性分别为94%、91%、91%和94%;SOCS-3基因cDNA全长690 bp,编码229个氨基酸的前体蛋白,与人、大鼠和小鼠的氨基酸序列一致性高达94%以上;SOCS-4基因cDNA全长1404 bp,整个编码区没有内含子插入,编码441个氨基酸的前体蛋白,与人、大鼠和小鼠的氨基酸序列一致性分别为97%,89%和86%.氨基酸结构分析显示,长白猪SOCS-1,SOCS-3和SOCS-4基因都具有典型的中央SH2结构域和C末端有40个氨基酸的SOCS Box结构域;SOCS-4有长约285个氨基酸的N末端,且没有特殊的结合基序,其长末端存在的生理意义有待进一步研究.采用RT-PCR方法,对长白猪SOCS-1,SOCS-3和SOCS-4基因进行组织表达分析.结果显示它们在所有组织中都有表达.

    2000-01-01

    Full Text Available El embalse La Mariposa localizado en la parte alta de la cuenca del río El Valle, municipio Los Salias, estado Miranda, Venezuela ha venido cumpliendo el papel de receptor de aguas crudas para abastecer una considerable parte de las demandas de agua potable por parte de la ciudad de Caracas. En 1949, cuando se pone en funcionamiento el Sistema, Caracas albergaba menos de un millón de habitantes, mientras que en la cuenca del Embalse se ubicaban unas 650 viviendas con una población aproximada de 3.000 habitantes. Actualmente, la situación ha cambiado radicalmente, producto del crecimiento poblacional y la expansión física urbana, con impactos directos de ocupación en la cuenca del Embalse, trayendo consigo factores que afectan la capacidad receptora del sistema y la calidad de sus aguas. Metodológicamente se ha procedido a levantar una cartografía básica utilizando S.I.G y posteriormente se ha realizado un trabajo de campo para indagar la magnitud del proceso de ocupación e identificar los factores generadores de deterioro al Sistema. Se ha detectado un fuerte proceso de sedimentación que afecta el espacio receptor del Embalse y sus aguas.

  7. Structure of BT-3984, a member of the SusD/RagB family of nutrient-binding molecules

    International Nuclear Information System (INIS)

    The crystal structure of BT-3984, a SusD-family protein, reveals a TPR N-terminal region providing support for a loop-rich C-terminal subdomain and suggests possible interfaces involved in sus complex formation. The crystal structure of the Bacteroides thetaiotaomicron protein BT-3984 was determined to a resolution of 1.7 Å and was the first structure to be determined from the extensive SusD family of polysaccharide-binding proteins. SusD is an essential component of the sus operon that defines the paradigm for glycan utilization in dominant members of the human gut microbiota. Structural analysis of BT-3984 revealed an N-terminal region containing several tetratricopeptide repeats (TPRs), while the signature C-terminal region is less structured and contains extensive loop regions. Sequence and structure analysis of BT-3984 suggests the presence of binding interfaces for other proteins from the polysaccharide-utilization complex

Con base en las teorías de juegos y de redes se analizan las interacciones estratégicas entre los narcotraficantes y sus agentes. Se prueba que la densidad de las redes es un determinante fundamental de la probabilidad de supervivencia de los narcotraficantes y de los salarios que pagan a sus hombres; y que la eficacia de las políticas de represión de la oferta depende de la densidad de las redes.

  12. Evaluation of crevice corrosion initiation condition and repassivation condition of SUS304L

    International Nuclear Information System (INIS)

    Crevice corrosion has been concerned in the Fukushima Daiichi Nuclear Power Station, since seawater was injected to make up water level as part of the emergency action. To evaluate structural integrity, it is important to investigate whether crevice corrosion occurred. The purpose of this study is to investigate conditions of crevice corrosion initiation and repassivation of SUS304L. SUS304L specimens with acrylic crevice were held at constant electrochemical potentials in 1000ppm Cl- solution. It was investigated the crevice corrosion initiation time as a function of the holding potential. Next, crevice-corroding specimens were held at constant electrochemical potentials in 1000ppm Cl- solution. It was investigated the repassivation time against the holding potential. The initiation potential and repassivation potential are in good agreement with ER,CREV obtained according to the JIS standard. (author)

  13. Effect of Pulse Current on the Tensile Deformation of SUS304 Stainless Steel

    Science.gov (United States)

    Li, Xifeng; Wang, Shen; Zhao, Shuangjun; Ding, Wei; Chen, Jun; Wu, Guohong

    2015-12-01

    The effect of pulse current on the mechanical properties of SUS304 metastable austenitic stainless steel was studied by tension test with and without air-cooling under different current densities. The microstructural variations at different conditions were also studied by SEM, TEM, and Feritscope. A negative effect on the plasticity was observed when current pulse was applied without air-cooling. But when Joule heating resulting from current pulse was excluded by air-cooling, the elongation of SUS304 stainless steel was increased to 72.4% at a current density of 2.95 A/mm2, which is 23.3% higher than that tested without pulse current at room temperature. Pulse current can decrease the dislocation density and dislocation pile-ups. Furthermore, EP effect from pulse current can accelerate martensitic transformation and enhance TRIP effect. The mechanism of current-induced martensitic transformation was discussed from Gibbs free energy change.

    Full Text Available SUS440 is a high-carbon stainless steel, and its martensite matrix has high heat resistance, high corrosion resistance, and high pressure resistance. It has been widely used in mechanical parts and critical materials. However, the SUS440 martempered matrix has reliability problems in thin plate applications and thus research uses different austempering heat treatments (tempering temperature: 200 °C–400 °C to obtain a matrix containing bainite, retained austenite, martensite, and the M7C3 phase to investigate the relationships between the resulting microstructure and tensile mechanical properties. Experimental data showed that the austempering conditions of the specimen affected the volume fraction of phases and distribution of carbides. After austenitizing heat treatment (1080 °C for 30 min, the austempering of the SUS440 thin plates was carried out at a salt-bath temperature 300 °C for 120 min and water quenching was then used to obtain the bainite matrix with fine carbides, with the resulting material having a higher tensile fracture strength and average hardness (HRA 76 makes it suitable for use as a high-strength thin plate for industrial applications.

    Objective To investigate the outpatient access to nuclear medicine procedures by means of the Brazilian Unified Health System (SUS), analyzing the correspondence between data provided by this system and those from Comissão Nacional de Energia Nuclear (CNEN) (National Commission of Nuclear Energy). Materials and Methods Data provided by Datasus regarding number of scintillation chambers, outpatient procedures performed from 2008 to 2012, administrative responsibility for such procedures, type of service providers and outsourced services were retrieved and evaluated. Also, such data were compared with those from institutions certified by CNEN. Results The present study demonstrated that the system still lacks maturity in terms of correct data input, particularly regarding equipment available. It was possible to list the most common procedures and check the growth of the specialty along the study period. Private centers are responsible for most of the procedures covered and reimbursed by SUS. However, many healthcare facilities are not certified by CNEN. Conclusion Datasus provides relevant data for analysis as done in the present study, although some issues still require attention. The present study has quantitatively depicted the Brazilian reality regarding access to nuclear medicine procedures offered by/for SUS. PMID:25741070

    2016-01-01

    Version 1.6.0 of the code SusHi is presented. Concerning inclusive CP-even Higgs production in gluon fusion, the following new features with respect to previous versions have been implemented: expansion of the partonic cross section in the soft limit, i.e. around $x=M_H^2/\\hat{s}\\to 1$; N$^3$LO QCD corrections in terms of the soft expansion; top-quark mass suppressed terms through NNLO; matching to the cross section at $x\\to 0$ through N$^3$LO. For CP-even and -odd scalars, an efficient evaluation of the renormalization-scale dependence is included, and effects of dimension-5 operators can be studied, which we demonstrate for the SM Higgs boson and for a CP-even scalar with a mass of $750$ GeV. In addition, as a generalization of the previously available $b\\bar{b}\\to H$ cross section, SusHi 1.6.0 provides the cross section for charged and neutral Higgs production in the annihilation of arbitrary heavy quarks. At fixed order in perturbation theory, SusHi thus allows to obtain Higgs cross-section predictions in...

    2013-01-01

    In the context of the Unified Health System (SUS), health actions and services constitute a social right to be guaranteed by the State and managed under the responsibility of three autonomous spheres of government. This is a holistic multiple case study with a qualitative approach based on the assumptions of Comprehensive Everyday Sociology, which originated from a PhD thesis. It sought to understand the construction of comprehensive health practices in the daily work of family health teams and managers of the cities in Vale do Jequitinhonha - Minas Gerais, Brazil. The individuals studied were professionals from the Family Health Teams, support staff and managers with a total of 48 participants. In order to reveal the construction of the whole, the data show that "SUS is universal, but quotas are the norm." Bearing in mind its limitations, it is difficult to ensure that SUS is a right for all. Thus, regulation is essential to order, guide, define and optimize the use of resources available for comprehensive care and also guarantee public access to actions and services in a timely and equitable manner.

El Autor amplia en este texto sus estudios sobre la comunicación que humaniza, que es aquella que desde los orígenes de las sociedades humanas ha proporcionado a lo largo de la historia, visiones de la comunidad y del mundo circundante que orientan el esfuerzo colectivo para reproducir las organizaciones sociales y sus identidades. Muestra que los grupos humanos han utilizado la comunicación colectiva, para operar con los vínculos entre Naturaleza y Sociedad. Compara dos concepciones contrapuestas de ese vinculo: la primigenia y la actual. Cada una de esas concepciones, ha determinado el papel de la comunicación en la existencia de la humanidad y de sus sociedades.

  10. Microstructure and mechanical properties of annealed SUS 304H austenitic stainless steel with copper

    International Nuclear Information System (INIS)

    Research highlights: → SUS 304H austenitic stainless steel containing 3 wt.% Cu was annealed at 700 deg. C for up to 100 h. → Microstructure and mechanical properties of annealed alloys are examined. → Nano-sized Cu-rich precipitation upon annealing. → Strength of the alloy remains invariant with annealing whereas ductility improves. → Fatigue crack growth threshold of 3 wt.% Cu added alloy increases with annealing. - Abstract: An experimental investigation into the effect of Cu on the mechanical properties of 0 and 3 wt.% Cu added SUS 304H austenitic stainless steel upon annealing at 700 deg. C for up to 100 h was conducted. Optical microscopy reveals grain coarsening in both the alloys upon annealing. Observations by transmission electron microscopy revealed the precipitation of nanometer-sized spherical Cu particles distributed within the austenitic grains and the presence of carbides at the dislocations. Both the yield and ultimate tensile strengths of the alloys were found to remain invariant with annealing. Tensile ductility and the threshold stress intensity factor range for fatigue crack growth for 3 wt.% Cu added alloy increase with annealing. These are attributed to the grain coarsening with annealing. In all, the addition of Cu to SUS 304H does not affect the mechanical performance adversely while improving creep resistance.

    The aid lent by the emergency services is the object of this paper, which aims to assess the emergency service of the QualiSUS program. The study is descriptive with the application of a questionnaire to the responsible of the emergency services in eight hospitals. The emergency services were always overcrowded, and the causes pointed were the low resolutivity of basic attention and the precariousness of the hospital network. Contributing to this there is the primary care decreased resolutivity and the precariousness of the hospital network. Six hospitals do not manage the emergency service. The entrance system is not organized and only three hospitals work with risk classification. All of them refer difficulties with internal and external services. The hardest pathologies to refer to other services are the chronicles, neurological and social. The professionals do not have specific qualification and the precariousness job contracts do not contribute neither for the professional's fixation nor for his qualification. Clinical protocols are used by one service. It was noticed the influence of the QualiSUS in the hospitals. The failure of the health services network interferes with the emergency patient's profile. The investment of the QualiSUS cannot be restrained to the hospital. Emergency should be more integrated to the system and hospital. The qualification of human resources is indispensable as well as the bed's regulation. PMID:19851601

  13. Oxidation behavior of modified SUS316 (PNC316) stainless steel under low oxygen partial pressure

    International Nuclear Information System (INIS)

    Oxidation behaviors of modified SUS316 (PNC316) and SUS316 stainless steels were investigated under the low oxygen partial pressure of 10-31-10-22 atm at 600-800 deg. C. Oxygen uptake by these materials parabolically increased with time, and the kinetic rate constants depended on both oxygen partial pressure and temperature. Thus, semi-empirical equations of the parabolic rate constants were obtained to be 2.70x104exp(-109/RT)PO20.279 for PNC316 and 9.23x104exp(-98/RT)PO20.313 for SUS316. For the duplex layer formed under the low oxygen partial pressure, the inner layer consisted of such oxides as Cr2O3 and FeCr2O4, while the outer layer consisted of non-oxidized α-Fe. Furthermore, oxidation along the grain boundaries was observed for samples oxidized for a long time. From the point of view of fuel cladding chemical interaction evaluation at high burn-up fuel for fast reactors, it is interesting that formation of non-oxidized α-Fe was observed under the low oxygen partial pressure

    Full Text Available Este debate discute questões relacionadas ao financiamento do Sistema Único de Saúde (SUS. Na primeira parte, Ruben de Mattos defende a criação de dispositivos para a elevação progressiva dos gastos públicos em saúde. Segundo o debatedor, o maior desafio do governo será viabilizar - e sustentar - um sistema que garanta, de fato, o acesso universal e igualitário. Mattos também destaca a importância dos repasses federais entre os níveis de governos, por vê-los como instrumentos capazes de reduzir as desigualdades entre as regiões e incentivar políticas que contribuam para a consolidação do SUS. Na segunda parte, Nilson do Rosário afirma que o ajuste fiscal da década de 1990, conseqüência da política de estabilização monetária, limitou a capacidade de financiamento governamental na atenção à saúde, gerando efeitos perversos devido à ampliação da desigualdade social. A seguir, explica como o setor saúde respondeu às exigências de ajuste macroeconômico nas despesas públicas através de estratégias substitutivas, contexto em que o Programa de Saúde da Família (PSF se expandiu rapidamente, tornando-se estratégico na agenda da ampliação da atenção ambulatorial básica do país.This work discusses some of the issues related to the funding of the Brazilian National Health Service (SUS. In the first part of the paper, Ruben de Mattos advocates the creation of devices to guarantee a progressive increase in the public health budget. In the debater's view, the greatest challenge facing the government is the development - and the maintenance - of a system that can de facto guarantee universal and equalitarian access. Mattos also emphasizes the importance of the federal government's transfers of funds to local governments since the latter are seen as instrumental in the attempts to reduce inequality between regions and to encourage policies that will contribute to the SUS' consolidation.

    2014-07-01

    Full Text Available El artículo analiza la percepción que tiene una muestra representativa de la población española de entre 12 y 18 años sobre la protección de sus derechos en las cadenas de televisión. Para conseguir este objetivo, se aplicó un cuestionario de 59 preguntas diseñado para una investigación más amplia en la que se analizaba la opinión de los menores sobre la protección de sus derechos en la televisión y en Internet. Ninguna pregunta del cuestionario se refería a cadenas o programas concretos identificados por los investigadores y la información sobre estos partía de la propia opinión de los adolescentes. Los resultados que se presentan se refieren a los datos sobre televisión y, más concretamente, al respeto por los derechos fundamentales de los telespectadores en general, y de los de los menores en particular. De estos resultados se concluye que los adolescentes perciben claramente la vulneración de los derechos de igualdad, dignidad e intimidad, a la información objetiva veraz y plural y a la libre expresión y opinión –especialmente cuando ésta se refiere a los niños–. Igualmente muestran una postura crítica y de rechazo hacia los tipos de programas que no respetan sus derechos. Se propone utilizar esta capacidad crítica de los telespectadores desde una doble perspectiva: por una parte para crear escuela de ciudadanía y, por otra, para generar una sociedad más justa y equitativa.

Foi aplicado um questionário a 40 primíparas no puerpério imediato comperguntas semi-estruturadas. Ao comparar duas realidades diferentes, concluiu-se que alguns dos direitos das parturientes preconizados pela OMS não estavam sendo respeitados, especialmente onde não havia a implantação do parto humanizado, pois não era permitida a entrada de acompanhante e nem utilizadas técnicas de relaxamento para a parturiente, evidenciando assim que algumas instituições necessitam intensificar esses cuidados para melhorar a qualidade do atendimento prestado.This descriptive study was conducted in maternities assisted by the Brazilian Health System (SUS, in the cities of Guarapuava and Londrina, State of Paraná.

    Full Text Available Este artigo analisa o grau de progressividade dos tributos que financiam o Sistema Único de Saúde (SUS. Nele são identificados os principais tributos que financiam o SUS e, com base nos microdados da Pesquisa de Orçamentos Familiares 2002-2003, é inferida a distribuição do ônus do pagamento dos tributos diretos e indiretos que financiam o SUS e analisado o grau de progressividade dos mesmos. Foi, ainda, calculado o índice de Kakwani do financiamento do SUS, que sintetiza o grau de progressividade de um sistema tributário. Os dados mostraram que o índice de Kakwani do financiamento público é de ­0,008 e que, portanto, o financiamento do SUS corresponde a um sistema quase proporcional, que onera proporcionalmente à renda. Em uma sociedade com o grau de desigualdade da brasileira, que exibe um índice de Gini de 0,57, ter um financiamento do SUS proporcional é fortemente questionável sob a ótica da justiça social: ao contrário, seria desejável construir bases de financiamento do SUS francamente progressivas, de forma a contra-restar a fortíssima concentração de renda da nossa sociedade.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.

    A slow strain rate technique (SSRT) has recently been taken notice of as a rapid experimental method of stress corrosion cracking (SSC). Its correspondence to other experimental methods and availability for cracking susceptibility evalution and mechanism elucidation have been pointed out. This paper makes a crystallographic study on susceptibility to SCC and crack plane orientation, using SUS 310S steel single crystals with tensile axis orientation and examining nominal stress-strain curves in a boiling 42% MgCl {sub 2} solution by the SSRT. As a result, SSC occurs at strain rates below 2.38{times}10{sup {minus}5} S{sup {minus}1}, and tensile strength and fracture strains reduce with a decrease of the strain ratE. Moreover, it is found that the susceptibility index to SCC, which is the standard of the maximum stress ratio and the maximum stress strain ratio in the SCC testing solution/oil, decreases with a decrease of the strain rate, almost independent of tensile axis orientation. 9 refs., 11 figs.

Material y método: Dieciocho cerdos Large White con peso comprendido entre 20 y 25Kg fueron divididos en tres grupos de seis animales cada uno, con cada grupo formado por tres animales para evaluar la reparación de osteotomías con baja y alta velocidades en el hueso alveolar y tres en área extra-alveolar en los períodos de estudio de 7, 14 y 28 días. Resultados: Se observó que en el hueso alveolar en los tiempos post-operatorio de 14 y 28 días, los mejores resultados de reparación fueron en las osteotomías realizadas con baja velocidad, mientras que en el período post-operatorio de siete días, los resultados con alta velocidad fueron ligeramente mejores tanto en áreas alveolares como extra-alveolares. Para la metodología utilizada, no se encontraron diferencias estadísticamente significativas en el proceso de reparación ósea alveolar y extra-alveolar. Conclusiones: El proceso de reparación, por medio de análisis microscópico en la región alveolar y extra-alveolar, son similares con mejores resultados observados en osteotomías hechas con taladros en baja velocidad en los tiempos de catorce y veintiocho días y en el post-operatorio de siete días, los resultados con taladros de alta velocidad y la refrigeración fueron ligeramente mejores. Los trabajos de investigación utilizando cerdos como modelo animal son perfectamente viables.Introduction: Taking into account the bone repair process in pigs has shown a greater similarity among the histological variables studied compared to other biological

    Full Text Available Pretendemos establecer una relación entre la propuesta que hace Axel Honneth sobre el reconocimiento en el amor y las prácticas de crianza vividas por los integrantes de la familia, en especial entre los niños y las personas cuidadoras, para argumentar que en estas relaciones se da comienzo a la configuración de los niños como sujetos políticos. Para Honneth –quien retoma a Hegel y a Mead–, las primeras relaciones amorosas son sustanciales para vivir el reconocimiento afectivo –que se vive con los más íntimos–; en ellas la aceptación emocional va unida a sentimientos como la simpatía y la atracción, y les permite visibilizar al otro a partir de sus necesidades propias y su valor humano. Abordaremos la familia como primera estructura de acogida y primer escenario de socialización, para argumentar que los niños viven en sus familias, prácticas de reconocimiento de sí mismos, de los otros y del mundo que les rodea, lo cual, a nuestro modo de ver, hace parte de su proceso de socialización como sujetos políticos.

    A cavitating jet can improve fatigue life of materials, since impacts caused by cavitation bubble collapses produce a peening effect. In general, the cavitation impacts cause damages in hydraulic machinery. At an initial stage of the cavitation damage progress, the plastic deformation takes place and there is no mass loss. Then it is possible to do peening by the cavitating jet without the damage. In order to prove the peening effect, a residual stress on a surface of a stainless steel SUS304 was investigated by using a X-ray diffraction method. The stress components of the three different directions were measured changing with the exposure time of the cavitating jet, and then the principal stresses were calculated. The both principal stresses were changed from tension to compression. It can be concluded that the cavitating jet improves the residual stress on the surface of the stainless steel SUS304. The important parameters of the cavitating jet such as an optimum standoff distance were also shown.

  2. Estimation of residual stress distribution of Alloy600/SUS304 dissimilar weld joint

    International Nuclear Information System (INIS)

    This paper describes the estimation of residual stress distribution of Alloy600/SUS304 dissimilar weld joint in the nuclear power plant piping. The calculated results by two-dimensional axi-symmetric finite element method (FEM) modeling were compared with the measurements by non-destructive methods of the X-Ray diffraction and strain gauge procedures. In the thermal elasto-plastic analysis, two factors were considered. One is the geometric modeling of weld deformation and another is the modeling of heat flux in welding. Though thermal histories were affected by the modeling of weld deformation and heat flux, estimation of residual stress was robust to the modeling. Applicability of X-Ray diffraction method is also confirmed to measure axial residual stress at the surface of the welded piping, because the scatter between measured and calculated results were less than 50 MPa. It was confirmed that the axial residual stress distribution near the weld joint of Alloy600/SUS304 piping is estimated by FEM analysis and X-Ray diffraction method within acceptable accuracy.

A pesar de sus tempranos comienzos, el Derecho Internacional Privado comenzó a desarrollarse verdaderamente desde la década de los años 1980. Esta rama del derecho está constituida en China por las normas de conflictos de leyes, las normas de conflictos de jurisdicción, y el reconocimiento y la ejecución de resoluciones judiciales en materia civil y mercantil. A pesar de las diferentes opiniones sobre el mejor tipo de codificación entre una codificación completa o de cada materia, la más reciente ley china de derecho internacional, del 28 de octubre de 2010, codificó únicamente las normas de conflictos de leyes. Esta ley representa un progreso importante en el desarrollo del Derecho Internacional Privado en China a pesar de que algunas de sus disposiciones hayan sido muy criticadas.

    Full Text Available La paja de la caña de azúcar es un residuo beneficioso para el hombre cuando se usa correctamente. Su quema es altamente destructiva si se realiza indiscriminadamente, genera daños al suelo y emite partículas de carbón vegetal que pasan directamente al medio ambiente. La atmósfera se contamina, ocurren variaciones climatológicas y se daña sensiblemente el entorno que nos rodea. Se hizo una búsqueda bibliográfica sobre los principales usos de los residuos agrícolas de la caña (paja, donde se destacan sus potencialidades, fundamentalmente, en los países que cultivan esta gramínea para la producción azucarera.

    The shape, type, content, and dimension of nonmetallic inclusions in SUS304 strip produced by twin-roll strip casting were studied using scanning electron microscopy (SEM). The results show that the inclusions are mainly spherical Al2O3 and com- plex oxides composed of MnO, Al2O3., and SiO2. The percentage of fine oxides smaller than 3 μm reaches up to 51.8%. The theoreti- cal calculations show that fine oxides have precipitated during solidification. Therefore, it is concluded that during twin-roll strip casting, because of high cooling rate, the size of inclusions precipitated during solidification decreases, and the amount increases.

  13. Stable isotopic analysis on sus bones from the Wanfabozi site, Tonghua, Jilin

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    In order to study the sus diets and explore the possibility to distinguish domestic pig from wild boar through dietary analysis, stable carbon and nitrogen isotopes of 28 pig bones from archaeological site of Wanfabozi in Tonghua City, Jilin Province were analyzed. The δ13C and δ15N values of uncontaminated bones show that the overall pigs in the site were generally herbivores and ate mainly C3 plants. Significant difference of δ15N values was observed between wild boar and domestic pigs, which may result from the higher consumption of animal protein in domestic pigs other than from that in wild boar, possibly from human leftover or waste,. The dietary difference between wild boar and domestic pigs has great potential to differentiate wild boar and domestic pigs in the early stage of pig domestication.

    La biomasa es el resultado de la transformación de la energía solar en energía química. El hombre a través de la historia la ha utilizado no solo para su alimentación sino también para la alimentación de sus animales. Los avances de la ciencia promovieron el desarrollo agrario basado en la revolución verde, la cual solo promueve la producción de alimentos ya sea de uso humano o animal, marginando la importancia de la biomasa como enriquecedor del recurso suelo al disponerse de los insumos nec...

  19. Investigation for anti-stress corrosion cracking of SUS 304 stainless steel weldments

    International Nuclear Information System (INIS)

    The anti-stress corrosion cracking method by current density of cathodic protection was studied for stress corrosion cracking of SUS 304 stainless steel weldments in the environment of various MgCl2 boiling solution (wt%). Main results obtained are as follows: 1) Under the conditions below the critical current density of cathodic protection for anti-stress corrosion cracking, the latent time of crack initiation of weld heat affected zone occurs more rapidly than that of base metal because of the phenomenon of sensitizing and softening caused by weld heat cycles. 2) Under the constant current density of cathodic protection, the anti-stress corrosion cracking of weld heat affected zone can be controlled by critical concentration of MgCl2 solution. 3) The critical current density of cathodic protection of weld heat affected zone increases in proportion to concentration of MgCl2 solution.

    Full Text Available En todas las culturas, las comidas festivas manifiestan la historia de la comunidad; así, en México se puede encontrar la identidad nacional ligada a los alimentos que se consumen en esas fechas especiales. El sistema semiótico culinario que analizamos se constituye por el conjunto de textos identificados como parte de la cultura mexicana. Partimos del modelo de la semiótica de la cultura con los planteamientos de Iury Lotman. Nos interesa presentar la semiosfera festiva culinaria de México para comprobar cómo a través de los textos culinarios se manifiesta la memoria de una cultura que se identifica por sus gustos culinarios.
