    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

    A total of 12 gastrointestinal tracts of wild boars (Sus scrofa) from western Iran (Luristan) were examined for protozoan infection between September 2000 and November 2001. Of 12 boars examined, 67% harbored one or more species of the following protozoa: Balantidium coli (25%), Tritrichomonas suis (25%), Blastocystis sp. (25%), Entamoeba polecki (17%), Entamoeba suis (8%), Iodamoeba butschlii (17%), and Chilomastix mesnili (8%). Four of these protozoan species also are reported in humans, and persons living in rural areas where wild boars are abundant should take precaution to avoid infection. PMID:15650104

    Anthrax, caused by Bacillus anthracis, is an acute disease affecting wildlife, livestock, and humans worldwide, although its impact on these populations is underappreciated. In Ukraine, surveillance is passive, and anthrax is often detected in livestock. However, wildlife is not subject to surveillance, although anthrax deaths (such as in wild boar, Sus scrofa) have been documented. The wild boar is a plentiful and widespread species in Ukraine and is frequently hunted. We initiated a screening study testing Ukrainian wild boar blood samples for antibodies to B. anthracis. We mapped results relative to known livestock anthrax hotspots. We discovered evidence of exposure in wild boar up to 35 km from livestock anthrax hotspots and over 400 km from previous anthrax reports in boars. We make recommendations about using wildlife species as biosentinels for anthrax in Ukraine.

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.

    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...

    New tools to detect exposure of free-range Eurasian wild boar (Sus scrofa scrofa) to pathogenic mycobacteria would be valuable for improved disease surveillance and wildlife management. Two hundred sera from wild boar of known Mycobacterium bovis infection status were used to evaluate test suitability for the detection of antibodies against M. bovis and Mycobacterium avium subsp. paratuberculosis (or cross-reacting members of the M. avium complex). Two traditional enzyme-linked immunosorbent assays were evaluated using M. bovis purified protein derivative (bPPD) and paratuberculosis protoplasmatic antigen 3 (PPA3) as antigens, respectively, and a new point-of-care test format for bovine tuberculosis (bTB) that uses the innovative dual-path platform (DPP TB) test. The effect of individual factors (sex, age, lesions) on the diagnostic performance of the serologic tests was also determined. Although the DPP had a sensitivity of 89.6% and a specificity of 90.4%, for bPPD, the sensitivity was 79.2% and the specificity 100%. Both tests had a kappa agreement of 0.80. Sixty-five of 68 (95.6%) wild boar sera with antibodies against the PPA3 antigen corresponded to known M. bovis-infected wild boar. Significant differences were not observed in the bPPD and DPP readings among lesion categories or between age classes. A slight sex-related difference in sensitivity toward males in the DPP was found, but it was not detected in the bPPD enzyme-linked immunosorbent assay. The results support the use of antibody-based diagnostic tests for both large-scale and individual bTB testing of Eurasian wild boar and suggest that wild boar cannot be used as sentinels for infections caused by M. avium complex members.

    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

    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

    Full Text Available Abstract Background The wild boar (Sus scrofa is among the most widespread mammal species throughout the old world. Presently, studies concerning microsatellites in domestic pigs and wild boars have been carried out in order to investigate domestication, social behavior and general diversity patterns among either populations or breeds. The purpose of the current study is to develop a robust set of microsatellites markers for parentage analyses and individual identification. Findings A set of 14 previously reported microsatellites markers have been optimized and tested in three populations from Hungary, Portugal and Spain, in a total of 167 samples. The results indicate high probabilities of exclusion (0.99999, low probability of identity (2.0E-13 – 2.5E-9 and a parentage assignment of 100%. Conclusions Our results demonstrate that this set of markers is a useful and efficient tool for the individual identification and parentage assignment in wild boars.

    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

    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

  10. Genetic characterization and phylogeography of the wild boar Sus scrofa introduced into Uruguay

    Full Text Available The European wild boar Sus scrofa was first introduced into Uruguay, in southern South America during the early decades of the last century. Subsequently, and starting from founder populations, its range spread throughout the country and into the neighbouring Brazilian state Rio Grande do Sul. Due to the subsequent negative impact, it was officially declared a national pest. The main aim in the present study was to provide a more comprehensive scenario of wild boar differentiation in Uruguay, by using mtDNA markers to access the genetic characterization of populations at present undergoing rapid expansion. A high level of haplotype diversity, intermediate levels of nucleotide diversity and considerable population differentiation, were detected among sampled localities throughout major watercourses and catchment dams countrywide. Phylogenetic analysis revealed the existence of two different phylogroups, thereby reflecting two deliberate introduction events forming distantly genetic lineages in local wild boar populations. Our analysis lends support to the hypothesis that the invasive potential of populations emerge from introgressive hybridization with domestic pigs. On taking into account the appreciable differentiation and reduced migration between locales in wild boar populations, management strategies could be effective if each population were to be considered as a single management unit.

    Full Text Available This is the first attempt to estimate wild boar (Sus scrofa L. population density anddistribution in Greece. The study took place in 2004, in all 38 Greek counties of the mainland, as wellas in the larger forested Greek islands: Crete, Rodos, Samos, Lesvos, Limnos, Thasos, Corfu,Kefalonia and Zakinthos. It was observed that the species was present in every county in continentalGreece, with the exception of the two counties Attica and Evia. Attica, which includes the capital cityof Athens, is densely inhabited not allowing much space for wildlife. Evian is an island connected tothe mainland with a bridge. Wild boar can be found in an area around 19,495 km2, which is about 14%of the country. The mean distribution altitude reaches 686 ± 266 m. The average population numberwas estimated at 19,033 (0.98 ± 0, 21 ind/km2 individuals with maximum population level 23,030animals, and a minimum of 16,536. The highest mean density was observed in the prefecture of StereaHellas (1.26 ind/km2 and the lowest in the prefecture of Thrace (0.89 ind/km2. The maximum densitywas found in Sterea Hellas (3.14 ind/km2 and the minimum density in Thrace (0.13 ind/km2. Theabove results are expected to provide valuable information for the management of wild boar in Greece.

  12. Mandibular molar teeth and the development of mastication in the miniature pig (Sus scrofa).

    The only components of the orofacial complex that are fully developed as soon as they establish function are the occlusal surfaces of teeth. It is usually assumed that the occlusal surface of the molar teeth influences the orientation of the power stroke in spite of the fact that the data supporting this claim are lacking. The purpose of this longitudinal study was therefore to determine whether or not this hypothetical form-function relationship existed during development and whether or not it was related to growth. Serial dorsoventral and lateral radiography, and dorsoventral cineradiography were performed during natural feeding of 5 Hanford miniature pigs (Sus scrofa) of both genders between their 8th and 18th weeks. Sequences of power strokes were analyzed frame by frame and compared between sessions, and related to the position of the fourth primary mandibular molar (dm4). The changes in direction of the power stroke and in position of the dm4 relative to the midline were subsequently related to growth. The results of this study indicate that changes in orientation of the power stroke, though significant only on the balancing side, occur independently of the repositioning working and balancing side mandibular molars, as well as of skeletal growth. The null hypothesis that the mandibular primary molars influence the transverse orientation of the power stroke during growth is therefore refuted.

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

    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 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 Introduction: The literature is not clear in the ultra-structural manifestations of the vocal wrinkles after neural wound. Objective: To verify the alterations that occur in a vocal fold mechanically denervated. Method: In this prospective study, it were utilized 15 hogs of commercial race (Sus scrofa domesticates, with age of 4 to 12 weeks. The animals were distributed in three groups, chosen at random. Everybody was submitted to the denervation of the right vocal fold, with surgical removal of a segment with three centimeters of the recurring right laryngeal nerve. After 45, 90 and 180 days of the operations, it was proceeded the biopsy of the vocal muscles, it was prosecuted the samples for transmission electron microscopy and, for the ultra-structural study, utilized the transmission electron microscopy Philips, model EM208S. Results: The biopsied groups with 45 and 90 days after operation of mechanical denervation, presented disorganization miofibrilar, only vestigial lines Z in many samples, as well like altered mithochondrions presenting limited sizes, and matrix mithocondrial rarefied with rare mithocondrial cristae present. The biopsied group with 180 days after operation of denervation, presented regular sarcomeres, mithocondrions with sizes and regular number with correct positioning between the sarcomerical units. Conclusion: The finds in the ultra-structure of the vocal muscles suggest to re enervation of the muscle being that the muscular mithochondrions were the most sensible structures to the denervated condition, successions by the cytoarchiteture of the miofibrilas; the finds in the ultra-structure of the vocal muscles suggests to reinervation of the muscle in the period of approximately six months.

    Full Text Available Abstract Background Anaplasma phagocytophilum infects a wide variety of hosts and causes granulocytic anaplasmosis in humans, horses and dogs and tick-borne fever in ruminants. Infection with A. phagocytophilum results in the modification of host gene expression and immune response. The objective of this research was to characterize gene expression in pigs (Sus scrofa naturally and experimentally infected with A. phagocytophilum trying to identify mechanisms that help to explain low infection prevalence in this species. Results For gene expression analysis in naturally infected pigs, microarray hybridization was used. The expression of differentially expressed immune response genes was analyzed by real-time RT-PCR in naturally and experimentally infected pigs. Results suggested that A. phagocytophilum infection affected cytoskeleton rearrangement and increased both innate and adaptive immune responses by up regulation of interleukin 1 receptor accessory protein-like 1 (IL1RAPL1, T-cell receptor alpha chain (TCR-alpha, thrombospondin 4 (TSP-4 and Gap junction protein alpha 1 (GJA1 genes. Higher serum levels of IL-1 beta, IL-8 and TNF-alpha in infected pigs when compared to controls supported data obtained at the mRNA level. Conclusions These results suggested that pigs are susceptible to A. phagocytophilum but control infection, particularly through activation of innate immune responses, phagocytosis and autophagy. This fact may account for the low infection prevalence detected in pigs in some regions and thus their low or no impact as a reservoir host for this pathogen. These results advanced our understanding of the molecular mechanisms at the host-pathogen interface and suggested a role for newly reported genes in the protection of pigs against A. phagocytophilum.

    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 Heavy metals are toxic elements naturally present in the environment which can be bioconcentrated by plants and animals and incorporated into food cycles. Thus the use of wildlife species as monitors is a useful tool to assess environmental pollution. Because of its ethological characteristics, wild boar is highly probable to be exposed to pollution, mainly by heavy metals. These pollutants, when present at high enough concentrations, can induce histological lesion in various tissues. The purpose of the present work was to investigate the levels of five metals (cadmium, copper, iron, lead and zinc in wild boar, Sus scrofa, originating from an Apennine area of Emilia Romagna, Northern Italy, and to evaluate any possible correlation with histological lesions eventually observed. Samples of several organs (liver, heart, kidney, diaphragm, abductor muscle, masseter, eye, testis, brain, lung and spleen were collected from hunted animals during winter 2001. Levels of metals were determined on freeze dried tissues employing microwave wet digestion. Toxicological analysis were performed by atomic absorption spectrophotometry and data expressed on a dry weight basis. Histopatological analyses were performed on fixed samples of the same tissue. Highest mean values were found in kidney for cadmium and copper (7 ± 1 ppm and 30 ± 2.6 ppm respectively and in liver for copper (21.16 ± 3.28 ppm, lead (2139 ± 680.6 ppb, iron (415.92 ± 24.41 ppm and zinc (94.76 ± 6.11 ppm. In all other tissues, mean concentrations of each metal were at low levels, and were comparable one another. A statistical difference was found for iron (p<0.05, copper (p<0.05 and cadmium (p<0.01 in kidney, in testis (p<0.01 for zinc and in liver for copper (p<0.05 and cadmium (p<0.01 as function of age cohorts. When sex was considered, a statistical difference was found for iron in eye, for copper in heart and for cadmium in heart and kidney. Histopatological analysis allowed

    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.

  3. δ18O values of Sus scrofa blood water and bone phosphate; a marked discrepancy between domestic and wild specimens.

    Longinelli, Antonio; Selmo, Enrico

    2011-12-30

    δ¹⁸O analyses of water in the blood of domestic and wild pigs indicated that large isotopic differences exist between domestic and wild specimens of the same species (Sus scrofa) living in the same area. Similar isotopic differences are found between the δ¹⁸O(PO₄³⁻) values of bones from the two groups of animals. When δ¹⁸O values obtained from recent wild boar bones are introduced in the equation of the isotopic scale determined for domestic pigs, totally unreliable δ¹⁸O values of local meteoric water are obtained. The δ¹⁸O(PO₄³⁻) values measured in three groups of modern wild boar specimens allow the calculation of a first approximate equation which is quite different from that of domestic pigs. This isotopic scale should be accurately re-calibrated for wild animals.

    Porcine endogenous retroviruses (PERV) are discussed as putative infectious agents in xenotransplantation. PERV classes A, B, and C harbor different envelope proteins. Two different types of long terminal repeat (LTR) structures exist, of which both are present only in PERV-A. One type of LTR contains a distinct repeat structure in U3, while the other is repeatless, conferring a lower level of transcriptional activity. Since the different LTR structures are distributed unequally among the proviruses and, apparently, PERV is the only virus harboring two different LTR structures, we were interested in determining which LTR is the ancestor. Replication-competent viruses can still be found today, suggesting an evolutionary recent origin. Our studies revealed that the age of PERV is at most 7.6 x 10(6) years, whereas the repeatless LTR type evolved approximately 3.4 x 10(6) years ago, being the phylogenetically younger structure. The age determined for PERV correlates with the time of separation between pigs (Suidae, Sus scrofa) and their closest relatives, American-born peccaries (Tayassuidae, Pecari tajacu), 7.4 x 10(6) years ago.

    Glutathione S-transferases (GSTs) play a key role in detoxification of xenobiotics in organisms. However, their other functions, especially response to the natural toxin cantharidin produced by beetles in the Meloidae and Oedemeridae families, are less known. We obtained GST cDNAs from three sources: Cydia pomonella (CpGSTd1), Sus scrofa (SsGSTα1), and Triticum aestivum (TaGSTf3). The predicted molecular mass is 24.19, 25.28 and 24.49 kDa, respectively. These proteins contain typical N-terminal and C-terminal domains. Recombinant GSTs were heterologously expressed in Escherichia coli as soluble fusion proteins. Their optimal activities are exhibited at pH 7.0-7.5 at 30 °C. Activity of CpGSTd1 is strongly inhibited by cantharidin and cantharidic acid, but is only slightly suppressed by the demethylated analog of cantharidin and cantharidic acid. Enzymatic assays revealed that cantharidin has no effect on SsGSTα1 activity, while it significantly stimulates TaGSTf3 activity, with an EC50 value of 0.3852 mM. Activities of these proteins are potently inhibited by the known GST competitive inhibitor: S-hexylglutathione (GTX). Our results suggest that these GSTs from different sources share similar structural and biochemical characteristics. Our results also suggest that CpGSTd1 might act as a binding protein with cantharidin and its analogs.

    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

    : Feral swine ( Sus scrofa ) are an invasive species and reservoir of numerous zoonotic pathogens in the US, and Texas leads the nation in the estimated population size of feral hogs. Texas also harbors enzootic transmission cycles of the protozoan parasite Trypanosoma cruzi , agent of Chagas disease. Given previous evidence that swine can serve as reservoirs of T. cruzi in Latin America and new evidence of triatomines (kissing bugs) feeding on swine in Texas, we measured the prevalence of T. cruzi infection in feral swine in Texas. From 2013 to 2014, we sampled blood and/or cardiac tissue from 78 feral swine across 14 Texas counties (seven with and seven without prior documentation of kissing bug occurrence) and used PCR and histopathology to detect T. cruzi infection. We determined an overall infection prevalence of 6% (3 of 54) based on PCR evaluation of cardiac tissue, and no blood samples were positive (n=72). All three positive pigs were from counties where kissing bugs are documented. No T. cruzi amastigotes were noted on histopathology (n=54). Sarcocysts were observed in 10 (18%) of the samples, five of which also had mild focal areas of degeneration and inflammatory cell infiltration. Eco-epidemiologic investigations can provide an assessment of contributions of feral hogs to maintenance of T. cruzi across a landscape to help protect human and animal health.

    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.

    Two data libraries based on the 1974 US Census of Agriculture are described. The data packages (AGDATC and AGDATG) are available from the Radiation Shielding Information Center (RSIC), Oak Ridge National Laboratory, Oak Ridge, Tennessee 37831. Agricultural production and land-use information by county (AGDATC) or by 1/2 by 1/2 degree longitude-latitude grid cell (AGDATG) provide geographical resolution of the data. The libraries were designed for use in risk assessment models that simulate the transport of radionuclides from sources of airborne release through food chains to man. However, they are also suitable for use in the assessment of other airborne pollutants that can affect man from a food ingestion pathway such as effluents from synfuels or coal-fired power plants. The principal significance of the data libraries is that they provide default location-specific food-chain transport parameters when site-specific information are unavailable. Plant food categories in the data libraries include leafy vegetables, vegetables and fruits exposed to direct deposition of airborne pollutants, vegetables and fruits protected from direct deposition, and grains. Livestock feeds are also tabulated in four categories: pasture, grain, hay, and silage. Pasture was estimated by a material balance of cattle and sheep inventories, forage feed requirements, and reported harvested forage. Cattle (Bos spp.), sheep (Ovis aries), goat (Capra hircus), hog (Sus scrofa), chicken (Gallus domesticus), and turkey (Meleagris gallopavo) inventories or sales are also tabulated in the data libraries and can be used to provide estimates of meat, eggs, and milk production. Honey production also is given. Population, irrigation, and meteorological information are also listed.

    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

  15. The stress response and exploratory behaviour in Yucatan minipigs (Sus scrofa): Relations to sex and social rank.

    According to the coping styles hypothesis, an individual demonstrates an integrated behavioural and physiological response to environmental challenge that is consistent over time and across situations. Individual consistency in behavioural responses to challenge has been documented across the animal kingdom. Comparatively few studies, however, have examined inter-individual variation in the physiological response, namely glucocorticoid and catecholamine levels, the stress hormones secreted by the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system, respectively. Variation in coping styles between individuals may be explained in part by differences in social rank and sex. Using 20 Yucatan minipigs (Sus scrofa) we: (1) investigated the existence of consistent inter-individual variation in exploratory behaviour and the hormonal stress response, and tested for correlations as predicted by the coping styles hypothesis; and (2) evaluated whether inter-individual behavioural and hormonal variation is related to social rank and sex. Salivary stress biomarkers (cortisol, alpha-amylase, chromogranin A) were assessed in the presence and absence of a stressor consisting of social isolation in a crate for 10 min. Principal components analysis on a set of behavioural variables revealed two traits, which we labelled exploratory tendency and neophobia. Neither exploratory tendency nor neophobia predicted the physiological stress response. Subordinate pigs exhibited higher catecholamine levels compared to dominant conspecifics. We observed sex differences in the repeatability of salivary stress markers and reactivity of the stress systems. The results do not provide support for the existence of behavioural-physiological coping styles in pigs. Sex is an important determinant of the physiological stress response and warrants consideration in research addressing behavioural and hormonal variation.

    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.

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.

    Interest in soil C storage and release has increased in recent years. In addition to factors such as climate/land-use change, vertebrate animals can have a considerable impact on soil CO(2) emissions. To date, most research has considered herbivores, while the impact of omnivorous animals has rarely been investigated. Our goal was to determine how European wild boars (Sus scrofa L.), large omnivores that consume soil-inhabiting animals and belowground plant parts by grubbing in the soil, affect soil C dynamics. We measured soil respiration (CO(2)), temperature, and moisture on paired grubbed and non-grubbed plots in six hardwood forest stands for a 3-year period and sampled fine root and microbial biomass at the beginning and after 2 years of the study. We also measured the percentage of freshly disturbed forest soil within the larger surroundings of each stand and used this information together with hunting statistics and forest cover data to model the total amount of CO(2) released from Swiss forest soils due to grubbing during 1 year. Soil CO(2) emissions were significantly higher on grubbed compared to non-grubbed plots during the study. On average 23.1% more CO(2) was released from these plots, which we associated with potential alterations in CO(2) diffusion rates, incorporation of litter into the mineral soil and higher fine root/microbial biomass. Thus, wild boars considerably increased the small-scale heterogeneity of soil properties. Roughly 1% of Switzerland's surface area is similar to our sites (boar density/forest cover). Given the range of forest soil disturbance of 27-54% at our sites, the geographic information system model predicted that boar grubbing would lead to the release of an additional 49,731.10-98,454.74 t CO(2) year(-1). These values are relatively small compared to total soil emissions estimated for Swiss hardwood forests and suggest that boars will have little effect on large-scale emissions unless their numbers increase and their

    Full Text Available Mycobacterium celatum, a slowly growing potentially pathogenic mycobacterium first described in humans, is regarded as an uncommon cause of human infection, though capable of inducing invasive disease in immunocompromised hosts. According to some reports, a serious disease due to M. celatum may also occur in individuals with no apparent immunodeficiency. In animals, an M. celatum-related disease has been described in three cases only: twice in a domestic ferret (Mustela putorius furo and once in a white-tailed trogon (Trogon viridis. In this paper, we report the first detection of M. celatum in a domestic pig (Sus scrofa domestica and roe deer (Capreolus capreolus. A nation-wide overview of human M. celatum infections recorded in Slovenia between 2000 and 2010 is also given. Pulmonary disease due to M. celatum was recognized in one patient with a history of a preexisting lung disease.

    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

    Trypsin is one of the most important enzymatic tools in proteomics and biopharmaceutical studies. Here, we describe the complete recombinant expression and purification from a trypsinogen expression vector construct. The Sus scrofa cationic trypsin gene with a propeptide sequence was optimized according to Escherichia coli codon-usage bias and chemically synthesized. The gene was inserted into pET-11c plasmid to yield an expression vector. Using high-density E. coli fed-batch fermentation, trypsinogen was expressed in inclusion bodies at 1.47 g/L. The inclusion body was refolded with a high yield of 36%. The purified trypsinogen was then activated to produce trypsin. To address stability problems, the trypsin thus produced was acetylated. The final product was generated upon gel filtration. The final yield of acetylated trypsin was 182 mg/L from a 5-L fermenter. Our acetylated trypsin product demonstrated higher BAEE activity (30,100 BAEE unit/mg) than a commercial product (9500 BAEE unit/mg, Promega). It also demonstrated resistance to autolysis. This is the first report of production of acetylated recombinant trypsin that is stable and suitable for scale-up.

    Full Text Available Cadaverous entomofauna successions vary according to the region, environment, and climate, and such differences may occur within the same country due to seasonal variations. The present study aimed to analyze and compare the dipterofauna that visit or colonize carcasses in the urban and coastal areas of São Paulo, Brazil, during summer and winter seasons. Four swine (Sus scrofa Linné, 1758 carcasses of approximately 12 kg were used. The animals were previously euthanized and then placed in metal cages covered with a flight intercept trap (Shannon, modified. In total, 10,495 flies from 39 families were collected, with 15 species belonging to the Calliphoridae family, 14 species belonging to the Fanniidae family, 43 species belonging to the Muscidae family, and 22 species belonging to the Sarcophagidae family. Flies from these four families visited all carcasses; however, they did not show the highest visitation frequencies in all of the trials. Species variations occurred between the experiments that were performed at different locations and in different seasons. Furthermore, difference in the number of insects attracted to each stage of decomposition was observed. In addition to the four families highlighted above, the families Phoridae, Sepsidae, Otitidae, and Piophilidae were observed in all carcasses.

    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.

    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

    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.

    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 biosecurity issues, emergency-response planning, and conflicts between livestock and other natural resources.

    Full Text Available Aquatic and semiaquatic mammals have the capacity of breath hold (apnea diving. Northern elephant seals (Mirounga angustirostris have the ability to perform deep and long duration dives; during a routine dive, adults can hold their breath for 25 min. Neotropical river otters (Lontra longicaudis annectens can hold their breath for about 30 sec. Such periods of apnea may result in reduced oxygen concentration (hypoxia and reduced blood supply (ischemia to tissues. Production of adenosine 5’-triphosphate (ATP requires oxygen, and most mammalian species, like the domestic pig (Sus scrofa, are not adapted to tolerate hypoxia and ischemia, conditions that result in ATP degradation. The objective of this study was to explore the differences in purine synthesis and recycling in erythrocytes and plasma of three mammalian species adapted to different environments: aquatic (northern elephant seal (n=11, semiaquatic (neotropical river otter (n=4 and terrestrial (domestic pig (n=11. Enzymatic activity of hypoxanthine-guanine phosphoribosyltransferase (HGPRT was determined by spectrophotometry, and activity of inosine 5’-monophosphate dehydrogenase (IMPDH and the concentration of hypoxanthine (HX, inosine 5’-monophosphate (IMP, adenosine 5’-monophosphate (AMP, adenosine 5’-diphosphate (ADP, ATP, guanosine 5’-diphosphate (GDP, guanosine 5’-triphosphate (GTP, and xanthosine 5’-monophosphate (XMP were determined by high-performance liquid chromatography (HPLC. The activities of HGPRT and IMPDH and the concentration of HX, IMP, AMP, ADP, ATP, GTP and XMP in erythrocytes of domestic pigs were higher than in erythrocytes of northern elephant seals and river otters. These results suggest that under basal conditions (no diving, sleep apnea or exercise, aquatic and semiaquatic mammals have less purine mobilization than their terrestrial counterparts.

    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

  18. 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.

    Although quantitative trait loci (QTLs) for number of thoracic-lumbar vertebrae have been identiifed onSus scrofa chromo-somes (SSCs) 1 and 7, the inlfuence of these QTLs on the thoracic and lumbar vertebrae is not clear. The aim of this study was to identify single nucleotide polymorphisms (SNPs) associated with total number of thoracic-lumbar vertebrae and for each trait (number of thoracic and lumbar vertebrae) separately. A total of 581 individuals from an F2 Large White×Minzhu population were genotyped using an SNP60K chip. Performing a genome-wide association study (GWAS) for total number of thoracic-lumbar vertebrae, 38 signiifcant SNPs were identiifed in two QTL regions located on SSC1 and SSC7. Performing a GWAS for number of thoracic vertebrae only, 72 signiifcant SNPs were located on SSC7. While performing a GWAS for number of lumbar vertebrae only, 17 signiifcant SNPs were identiifed on SSC1. Gene mining suggested that the gene encoding orphan nuclear receptor, germ cel nuclear factor (NR6A1) on SSC1 was a strong candidate affecting the number of lumbar vertebrae in pigs. Additionaly, genes encoding vertnin (VRTN), prospero homeobox 2 (PROX2), Finkel-Biskis-Jinkins murine osteosarcoma viral oncogene homolog (FOS), and transforming growth factor beta 3 (TGFB3) may be important candidates affecting the number of thoracic vertebrae in pigs. QTLs on SSC1 and SSC7 independently inlfuenced the numbers of tho-racic and lumbar vertebrae. These results shed light on the complex genetic background of vertebrae development in pigs.

  1. 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.

    The Brazilian Pantanal has been considered one of the richest and most diverse wetland ecosystems in the world. It is occupied by cattle ranching, and a variety of wildlife species share the same habitats with domestic livestock. We investigated infections of Trypanosoma evansi and Trypanosoma cruzi in the sympatric suiformes-collared peccary (Tayassu tajacu), white-lipped peccary (Tayassu pecari), and feral pig (Sus scrofa) by parasitological, serological, and molecular tests. Additionally, we evaluated the health status of both positive and negative suiformes by hematological and biochemical parameters. The results show that peccaries and feral pigs play an important role on the maintenance of both T. evansi and T. cruzi in the Brazilian Pantanal. Health impairment was observed only in the white-lipped peccary infected with T. evansi. Despite presenting low T. evansi parasitemia, all infected white-lipped peccaries displayed low hematocrit values and marked leucopenia. The hematological values showed that the T. evansi infection is more severe in young white-lipped peccaries. The presented data show that feral pigs and peccaries are immersed in the transmission net of both trypanosome species, T. cruzi and T. evansi, in the Pantanal region.

    The Suidae and the Dicotylidae (or Tayassuidae) are related mammalian families, both belonging to the artiodactyl suborder Suiformes, which diverged more than 37 million years ago. Cross-species chromosome painting was performed between the domestic pig (Sus scrofa; 2n = 38), a representative of the Suidae, and two species of the Dicotylidae: the collared peccary (Tayassu tajacu; 2n = 30) and the white-lipped peccary (T. pecari; 2n = 26). G-banded metaphase chromosomes of the two peccaries were hybridized with whole chromosome painting probes derived from domestic pig chromosomes 1-18 and X. For both peccary species, a total of 31 autosomal segments that are conserved between pig and peccary could be identified. The painting results confirm conclusions inferred from G-band analyses that the karyotypes of the collared peccary and the white-lipped peccary are largely different. The karyotypic heterogeneity of the Dicotylidae contrasts with the relative homogeneity among the karyotypes of the Suidae. For this difference between the Dicotylidae and the Suidae, a number of explanations are being postulated: 1) the extant peccaries are phylogenetically less closely related than is usually assumed; 2) the peccary genome is less stable than the genome of the pigs; and 3) special (e.g. biogeographical or biosocial) circumstances have facilitated the fixation of chromosome rearrangements in ancestral dicotylid populations.

    Full Text Available The aim of this data was to analyze morphology and function of the seminiferous tubule in adult wild boars. Testes removed by unilateral castration of five animals were used. The testicular parenchyma was composed by 82.1±2.2% of seminiferous tubule and 17.9±2.2% of intertubular tissue. The tubular diameter was 249.2±33.0 µm and the seminiferous tubule lenght per gram of testis was 19.3±4.9m. The spermatogonial mitoses efficiency coefficient, meiotic index and spermatogenesis efficiency were 10.34, 2.71 and 30.5 respectively. Each Sertoli cell supported about 13 germinatives cells. The hystometric parameters studied were very similar to those related for domestic boars, however, the wild boars intrinsic efficiency of spermatogenesis and Sertoli cells indexes were smaller than in domestic boars.Objetivou-se com esta pesquisa estudar as características morfométricas e funcionais dos túbulos seminíferos de javalis adultos. Utilizaram-se testículos de cinco animais submetidos a orquiectomia unilateral. O parênquima testicular foi composto por 82,1 ± 2,2% de túbulos seminíferos e 17,9 ± 2,2% de tecido intertubular. O diâmetro tubular foi de 249,2 ± 33,0µm e o comprimento dos túbulos seminíferos por grama de testículo foi de 19,3 ± 4,9m. O coeficiente de eficiência das mitoses espermatogônias, o rendimento meiótico e o rendimento geral da espermatogênese foram, respectivamente, 10,34, 2,71 e 30,50. Cada célula de Sértoli suportou cerca de 13 células germinativas. Conclui-se que os parâmetros histométricos estudados nesta pesquisa foram muito semelhantes aos valores relatados para suínos domésticos, entretanto, o rendimento intrínseco da espermatogênese e os índices de células de Sértoli de javalis foram relativamente baixos quando comparados com aqueles animais.

    Full Text Available Aim: The objective of this study was to investigate the chromosomal profile of indigenous pigs by computing morphometric measurements. Materials and Methods: A cytogenetic study was carried out in 60 indigenous pigs to analyze the chromosomal profile by employing the short term peripheral blood lymphocyte culture technique. Results: The modal chromosome number (2n in indigenous pigs was found to be 38 and a fundamental number of 64 as in the exotic. First chromosome was the longest pair, and thirteenth pair was the second largest while Y-chromosome was the smallest in the karyotype of the pig. The mean relative length, arm ratio, centromeric indices and morphological indices of chromosomes varied from 1.99±0.01 to 11.23±0.09, 1.04±0.05 to 2.95±0.02, 0.51±0.14 to 0.75±0.09 and 2.08±0.07 to 8.08±0.15%, respectively in indigenous pigs. Sex had no significant effect (p>0.05 on all the morphometric measurements studied. Conclusion: The present study revealed that among autosomes first five pairs were sub metacentric, next two pairs were sub telocentric (6-7, subsequent five pairs were metacentric (8-12 and remaining six pairs were telocentric (13-18, while both allosomes were metacentric. The chromosomal number, morphology and various morphometric measurements of the chromosomes of the indigenous pigs were almost similar to those established breeds reported in the literature.

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.

    体细胞克隆的效率一直较低,这可能与成熟前卵母细胞的质量有关.猪卵母细胞主要来源于屠宰场的废弃卵巢,这暗示,卵母细胞可能处于发情周期的各个阶段.因此,体细胞核转移之前有必要筛选优质卵母细胞.本研究旨在探讨亮甲酚蓝染色筛选及曲古抑菌素A (TSA)对东北野猪(Sus scrofa ussuricus)核移植胚发育的影响.卵丘卵母细胞复合体经亮甲酚蓝(BCB)染色后分三组:BCB+组(胞质着色,葡萄糖-6-磷酸脱氧酶(G6PDH)活性低)、BCB-组(胞质未着色,G6PDH活性高)和对照组(不使用亮甲酚蓝染色).卵母细胞体外成熟培养后,对卵母细胞进行核移植操作,来源于BCB+卵母细胞的核移植胚使用50 nmol/L TSA处理,未使用TSA处理的来源于BCB+卵母细胞的核移植胚作为对照组.结果表明,BCB+卵母细胞的直径显著大于BCB-组(P<0.05).来源于BCB+卵母细胞的核移植胚的初次卵裂时间要早于BCB-组及对照组.来源于BCB+卵母细胞的核移植胚的囊胚形成率显著高于BCB -组及对照组(P<0.05).且50 nmol/L TSA处理可将来源于BCB+卵母细胞的核移植囊胚率提高到(29.6±2.8)%(P<0.05).总之,来源于BCB+卵母细胞的核移植胚发育能力较强,且50 nmol/L的TSA可促进重构胚的体外发育.对卵母细胞进行BCB染色筛选并使用50 nmol/L的TSA处理重构胚,可提高东北野猪核移植重构胚的发育能力,为通过体细胞克隆法保护东北野猪资源创造条件.%The efficiency of somatic cell nuclear transfer (SCNT) is low, which may be related to the poor quality of the oocyte at the beginning of maturation. Porcine oocytes are commonly recovered from ovaries of slaughtered animals, which indicates that oocytes may be at various stages of the estrous cycle. Therefore, selection of high quality oocytes is necessarry for SCNT. This study was conducted to examine the effect of brilliant cresyl blue(BCB) staining and trichostain A(TSA) on the

    Full Text Available La necesidad de incrementar la producción de carne de cerdo en el país es de una palpitante actualidad, dado el bajo poder nutritivo de la dieta de nuestro pueblo, problema éste que tiende a agudizarse cada día debido a los altos costos de los elementos esenciales en la alimentación humana, tales como la carne, leche, etc. La industria porcina podría ser una buena solución a este grave problema ya que ella puede convertirse con un poco de estudio y de educación de nuestras gentes en una próspera y fuerte industria familiar, no tan restringida como se encuentra en la actualidad; sería necesario también racionalizar los sistemas de explotación con el fin de hacerlos más productivos. 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. Dadas las circunstancias de que un programa de educación campesina falla cuando es necesario hacer extensión con base en datos

    Full Text Available Documentamos la dieta del jabalí silvestre en el centro-sur de Chile basados en el examen de 20 estómagos colectados en los faldeos de volcán Mocho-Choshuenco (39°54' S, 72°02' O y en el Parque Nacional Vicente Pérez Rosales (41°03' S, 71°54' O. 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 %. With regard to the animal component, the wild boar in Chile consumes more (20 % volume of such items than in the United States of America (6 % and in Europe (7-13 %

Los animales no presentaban signos ni síntomas clínicos específicos atribuibles a la enfermedad. A la necropsia se observó: aumento de tamaño de los ganglios linfáticos, bazo, hígado y placas de Peyer; presencia de un puntillado o nodulaciones blancas de tamaño variable en hígado y riñón. Histopatológicamente estos tejidos tenían infiltraciones de células de origen linfoide, y de aspecto de linfosarcoma.Three cases of lymphosarcoma in industrially-bred pigs are described, in which two of the pigs had a live weight of 60 kg, and the third, a reproductive female, had a live weight of 280 kg. The animals did not present any signs, nor specific clinical symptoms attributable to the disease. During the necropsy, an enlargement in the size of the lymphatic nodes, spleen, liver, and Peyer’s Plate was observed, as was the presence of white spots or nodules of various sizes on the liver and kidney. The histopathology carried out on the tissue revealed the presence of cells of lymphoid origin, and of a histological aspect of lymphosarcoma.

    Full Text Available The pig, a representative of the artiodactyla clade, is one of the first animals domesticated, and has become an important agriculture animal as one of the major human nutritional sources of animal based protein. 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.

    Epidemiological studies have reported an association between high iron (Fe) levels and elevated risk of developing type 2 diabetes mellitus (T2D). It is believed that the formation of Fe-catalyzed hydroxyl radicals may contribute to the development of diabetes. Our goal was to determine the effect of a diet with a high Fe content on type 2 diabetic pigs. Four groups of piglets were studied: (1) control group, basal diet; (2) Fe group, basal diet with 3,000 ppm ferrous sulfate; (3) diabetic group (streptozotocin-induced type 2 diabetes) with basal diet; (4) diabetic/Fe group, diabetic animals/3,000 ppm ferrous sulfate. For 2 months, biochemical and hematological parameters were evaluated. Tissue samples of liver and duodenum were obtained to determine mRNA relative abundance of DMT1, ferroportin (Fpn), ferritin (Fn), hepcidin (Hpc), and transferrin receptor by qRT-PCR. Fe group presented increased levels of hematological (erythrocytes, hematocrit, and hemoglobin) and iron parameters. Diabetic/Fe group showed similar behavior as Fe group but in lesser extent. The relative abundance of different genes in the four study groups yielded a different expression pattern. DMT1 showed a lower expression in the two iron groups compared with control and diabetic animals, and Hpc showed an increased on its expression in Fe and diabetic/Fe groups. Diabetic/Fe group presents greater expression of Fn and Fpn. These results suggest that there is an interaction between Fe nutrition, inflammation, and oxidative stress in the diabetes development.

    On 23 clinical healthy pigs (2-4 months of age, body weight 13-42 kg) under ketamin-pentobarbital anaesthesia blood plasma coagulation parameters have been investigated. To obtain basic values 26 parameters were measured: number of thrombocytes, parameters of thrombelastogram and resonance-thrombogram, prothrombin time, activated partial thromboplastin time, thrombin time, reptilase time, factors I, II, V, VII, VIII, X, antithrombin III, plasminogen, alpha 1-antitrypsin, alpha 2-antiplasmin, alpha 2-macroglobulin, fibrin degradation products D and E and euglobulin lysis-time. Parameters calculated in percent should be measured against a pig plasma pool. Measurement against a human plasma pool are hardly valid in values higher than 100%. In comparison to man the results indicate modifications of fibrinogenesis and fibrinolysis in pigs.

    Full Text Available The main objective of this study was the assessment of the genetic structure and level of variability in the Portuguese wild boar population. A total of 65 wild boar blood samples were collected all over the continental territory, during 2002/03 and 2003/04 hunting seasons. A set of six microsatellite markers, developed for domestic pig, was used. Loci SW986 and SW828 presented a small number of alleles for the Portuguese population, whereas other l o c i, like SW1701 and SW1517, presented a high degree of polymorphism. From the six analysed l o c i, four presented significant deviation from Hardy-We i n b e rg equilibrium conditions, suggesting the existence of genetic structure in the population. Samples were divided into North, Centre and South groups according to the position of wild boar capture location in relation to rivers Douro and Tejo. All the FST estimates were statistically significant and the highest FST value was 0.08 (P<0.001, referring to the distance between Northern and Central groups. FCA analysis was also performed. The resulting bi-dimensional diagram suggests structuring of the Portuguese wild boar population.

    Full Text Available Until recently, geographic isolation has protected Britain from the widespread increases in wild boar populations seen elsewhere in Europe, but following the development of wild boar farming in the 1980s a number of escapes and releases have occurred, resulting in the re-establishment of the species in the wild in England. The present study monitored the establishment and presence of wild boar in England by collating reports of escapes or releases and ground-truthing evidence of animals in the wild. This data is used to give an up-to-date indication of the distribution of the species in England. In the twenty years from 1989/90 to 2008/9 an average of one to two escape/release incidents occurred each year, with individual incidents involving from one to more than 50 individuals. These have resulted in the establishment of at least four distinct populations, the largest of which probably has a pre-breeding population in excess of 200 animals. None of the escapes or releases involving five or fewer individuals is believed to have led to establishment of a population. Based on the availability of woodland, there is potential for a total population in England of around 30,000 – 40,000 animals. However, future development of local populations is likely to be constrained over much of the country because of low woodland cover and culling pressure, and it is likely to take many years for a population of this size to develop, if at all.

    Full Text Available Conjunctival swabs from 44 free-living wild boars culled during a demographic control programme applied in a Regional Park located in the Northern Italy were examined by 16S rRNA encoding gene nested PCR. 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.

    Colino–Rabanal, V. J.

    2012-01-01

    Full Text Available In recent decades, wild boar populations have increased both in number and distribution. This rise is partly related to the increase in cropland devoted to maize (Zea mays cultivation, as wild boar find food and refuge in these areas. This population expansion has led to an increase in the number of wild boar vehicle collisions (WBVCs. The goal of the present study was to evaluate a set of spatio–temporal factors that influence WBVCs related to maize crops on the Northern Spanish Plateau (the region of Castile and Leon. We compared the maize pattern with the factors related to total WBVC numbers. We observed that whereas the total occurrence of WBVCs usually increased with forest cover and speed and traffic volumes, maize areas were one of the main explanatory variables in plateau models. To avoid collisions in these areas in future, a number of mitigation measures are outlined.

    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.

    The biological role of the paranasal sinuses is obscure, can be elucidated through a cross-sectional growth study of the maxillary sinus in miniature pigs. The maxillary sinus area was obtained from lateral cephalograms of left skull halves of 103 female miniature pigs of known ages, from newborn to 24 months. Out of several nonlinear models, the growth of the maxillary sinus was best described with the Gompertz model. The first derivative of the Gompertz curve revealed an increase in the growth rates of the maxillary sinus until 4 months, after which sinus growth slowed down. The eruption of the permanent molars did not seem to have a significant influence on this growth pattern. Furthermore, growth in maxillary sinus size in the miniature pig does not follow growth in skull size closely, which showed the highest growth rates in newborn animals. In addition, a correlation analysis revealed that the relationship between maxillary sinus area and different characteristics of the masticatory apparatus (including linear cranial dimensions, and the dry weight of the masseter and zygomatico-mandibularis muscles) were influenced greatly by skull size. These results suggest that the existence of pneumatic cavities within the mammalian skull is not satisfactorily explained solely by an architectural theory. Epigenetic factors are likely to influence the final shape of the maxillary sinus.

    This study is about the craniofacial indices and neuromorphometrics of the Nigerian local pig and has been performed on twelve males and fourteen females of ages one and a half to two years. 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

    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.

    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.

    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.

    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.

    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.

    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.

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

    Full Text Available Abstract Superficial inguinal lymph nodes from 72 wild boars examined in a previous immunohistochemical (IHC study on porcine circovirus type 2 (PCV2 were selected for a PCV2 polymerase chain reaction (PCR analysis. Four of these lymph nodes were PCV2-IHC strongly positive with PMWS histological lesions (outcome 1, 6 weak to mild PCV2-IHC positive without PMWS histological lesions (outcome 2 and 62 PCV2-IHC negative. Considering IHC the gold standard for diagnosis, the aims of the study were to evaluate the suitability of the PCV2-DNA extraction from formalin-fixed and paraffin-embedded (FFPE tissue and the sensitivity and specificity of PCR under two IHC interpretations criteria: (A the sample was considered positive if the result was outcome 1; (B the sample was considered positive if the result was outcome 1 or 2. Under (A criteria, sensitivity and specificity of PCR were 100% and 89.7%, respectively; the Cohen's Kappa coefficient was 0.49. Under (B criteria, sensitivity and specificity of PCR were 80.0% and 95.2%, respectively; the Cohen's Kappa coefficient was 0.72. The high Cohen's Kappa coefficient under the (B interpretative criteria indicates good agreement between the two methods. In conclusion, 1 DNA extracted from FFPE specimens of wild boar is suitable for PCR and further represents a screening test for PCV2/PCVD (PCV2 Diseases investigations in wild boar as well; 2 routine histological sampling can also be useful for PCV2 virological studies in wild boar.

    Human settlement of Oceania marked the culmination of a global colonization process that began when humans first left Africa at least 90,000 years ago. The precise origins and dispersal routes of the Austronesian peoples and the associated Lapita culture remain contentious, and numerous disparate models of dispersal (based primarily on linguistic, genetic, and archeological data) have been proposed. Here, through the use of mtDNA from 781 modern and ancient Sus specimens, we provide evidence for an early human-mediated translocation of the Sulawesi warty pig (Sus celebensis) to Flores and Timor and two later separate human-mediated dispersals of domestic pig (Sus scrofa) through Island Southeast Asia into Oceania. Of the later dispersal routes, one is unequivocally associated with the Neolithic (Lapita) and later Polynesian migrations and links modern and archeological Javan, Sumatran, Wallacean, and Oceanic pigs with mainland Southeast Asian S. scrofa. Archeological and genetic evidence shows these pigs were certainly introduced to islands east of the Wallace Line, including New Guinea, and that so-called “wild” pigs within this region are most likely feral descendants of domestic pigs introduced by early agriculturalists. The other later pig dispersal links mainland East Asian pigs to western Micronesia, Taiwan, and the Philippines. These results provide important data with which to test current models for human dispersal in the region. PMID:17360400

    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.

    Patricia eNAGNAN-LE MEILLOUR

    2014-12-01

    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.

    During disease outbreaks, core temperature is a useful health metric in swine, due to the presence of pyrexia especially during the acute phase of infection. Despite technologic advances in other facets of swine production and health management, rectal thermometry continues to be the 'gold standard' for measuring core body temperature. However, for various reasons, collecting rectal temperatures can be difficult and unsafe depending on the housing modality. In addition, the delay between insertion of the rectal thermometer and obtaining a reading can affect measurement accuracy, especially when the pig requires physical restraint. Clearly safer, faster, and more accurate and precise temperature acquisition methods that necessitate minimal or no handling of swine are needed. We therefore compared rectal thermometers, subcutaneous microchips, and an inexpensive handheld infrared thermometer by measuring the core body temperature of 24 male castrated piglets at random intervals over a 5-wk period. The core body temperature (mean ± 1 SD) was 39.3±0.5 °C by rectal thermometry, 39.0±0.7 °C by microchip transponder, and 34.3±1.0 °C by infrared thermometry; these 3 values differed significantly. Although the readings obtain by using infrared thermometry were numerically lower than those from the other methods, it is arguably the safest method for assessing the core temperature of swine and showed strong relative correlation with rectal temperature.

    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.

    The merging of populations after an extended period of isolation and divergence is a common phenomenon, in natural settings as well as due to human interference. Individuals with such hybrid origins contain genomes that essentially form a mosaic of different histories and demographies. Pigs are an e

    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

    Recently, foraging strategies have been linked to the ability to use indirect visual information. More selective feeders should express a higher aversion against losses compared to non-selective feeders and should therefore be more prone to avoid empty food locations. To extend these findings, in this study, we present a series of studies investigating the use of direct and indirect visual and auditory information by an omnivorous but selective feeder-the domestic pig. Subjects had to choose between two buckets, with only one containing a reward. Before making a choice, the subjects in Experiment 1 (N = 8) received full information regarding both the baited and non-baited location, either in a visual or auditory domain. In this experiment, the subjects were able to use visual but not auditory cues to infer the location of the reward spontaneously. Additionally, four individuals learned to use auditory cues after a period of training. In Experiment 2 (N = 8), the pigs were given different amounts of visual information about the content of the buckets-lifting either both of the buckets (full information), the baited bucket (direct information), the empty bucket (indirect information) or no bucket at all (no information). The subjects as a group were able to use direct and indirect visual cues. However, over the course of the experiment, the performance dropped to chance level when indirect information was provided. A final experiment (N = 3) provided preliminary results for pigs' use of indirect auditory information to infer the location of a reward. We conclude that pigs at a very young age are able to make decisions based on indirect information in the visual domain, whereas their performance in the use of indirect auditory information warrants further investigation.

    Imprinted genes play significant roles in the regulation of fetal growth,development,function of the placenta and postnatal behavior in mammals,but little is known in pigs.In order to investigate the imprinting status of porcine retro-transposon like 1 (RTL1) and type 3 iodothyronine deiodinase (D103) genes,DNA samples of the parents and F1 animals,generated with reciprocal crosses between Large White and Meishan breeds,were isolated,and analyzed by reverse transcription polymerase chain reaction restriction fragment length polymorphism (RT-PCR-RFLP).The results demonstrated that the RTL1 gene was paternally expressed in 10 tissues,such as the skeletal muscle,heart,spleen,liver,kidney,lung,stomach,fat,small intestine and brain,and DI03 gene exhibited paternal expression in the skeletal muscle,heart,spleen,lung,stomach,and brain,in 2-month-old pigs.The association of RTL1 and DIO3 with carcass traits was further analyzed in the F2 population of Large White × Meishan pigs.The statistical results showed that the RTL1 A1101G polymorphism (EU781029) was significantly associated with lean meat percentage (LMP) and fat meat percentage (FMP) (P<0.05),while the DIO3 A744C polymorphism (AY533208) was not significantly associated with any carcass traits.These results indicate that the imprinting status of RTL1 and DIO3 is well kept across the mammalian species,and porcine RTL1 may have important roles in muscle growth and fat deposition.

    During disease outbreaks, core temperature is a useful health metric in swine, due to the presence of pyrexia especially during the acute phase of infection. Despite technologic advances in other facets of swine production and health management, rectal thermometry continues to be the 'gold standard' for measuring core body temperature. However, for various reasons, collecting rectal temperatures can be difficult and unsafe depending on the housing modality. In addition, the delay between insertion of the rectal thermometer and obtaining a reading can affect measurement accuracy, especially when the pig requires physical restraint. Clearly safer, faster, and more accurate and precise temperature acquisition methods that necessitate minimal or no handling of swine are needed. We therefore compared rectal thermometers, subcutaneous microchips, and an inexpensive handheld infrared thermometer by measuring the core body temperature of 24 male castrated piglets at random intervals over a 5-wk period. The core body temperature (mean ± 1 SD) was 39.3±0.5 °C by rectal thermometry, 39.0±0.7 °C by microchip transponder, and 34.3±1.0 °C by infrared thermometry; these 3 values differed significantly. Although the readings obtain by using infrared thermometry were numerically lower than those from the other methods, it is arguably the safest method for assessing the core temperature of swine and showed strong relative correlation with rectal temperature.

    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.

    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

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

    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

    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.

    The contamination of agricultural crops with Fusarium mycotoxins poses one of the greatest problems in food production. Wild boars live in specific habitats and are physiologically sensitive to Fusarium mycotoxins, therefore, they are an interesting model for studies investigating the effects of the discussed toxin, in particular under low-dose exposure. The objective of this study was to determine potential effects of Fusarium mycotoxins ingested with naturally contaminated food on reproductive function based on the proliferation and apoptotic indices of ovarian follicles in female wild boars. The experiment was conducted on 40 wild boars inhabiting north-eastern Poland. The effect of seasonal variations in the quantity and quality of ingested food on the concentrations of Fusarium mycotoxins and their metabolites in the blood of wild boars was analyzed. The observed differences in toxin levels were accompanied by changes in proliferation and apoptotic indices. Proliferation processes were most intense in autumn-winter and were least advanced in winter-spring. The intensity of apoptotic processes was inversely correlated with proliferation.

    Feeding behaviour of social animals can be influenced by the spatial distribution of resources. In domestic housing facilities growing pigs will often be fed from feeding sites confined to a small area, i.e. effectively a clumping of food resources. In the present experiment we investigated how...... feeding behaviour of growing pigs changed with increasing distance between feeding sites. During 20-min feeding tests, eight groups, each consisting of four growing pigs (35.4 ± 2.7 kg), were allowed to eat from four buckets containing food pellets placed in a test arena in a rectangular pattern....... The positions of the buckets, determined by their mutual distance, were close (15-25 cm), medium (245-290 cm) or far (460 cm). Feeding behaviour of the pigs was video recorded. There was a significant effect of feeding site position on all variables investigated except for the number of displacements from food...

    Full Text Available A RBMFC não poderia deixar de fazer alusão ao aniversário de 20 anos da promulgação do Sistema Único de Saúde (SUS. Este momento tem sido motivo de reflexão por todos aqueles que acompanham e militam, como nós, na sua construção. Em primeiro lugar cremos ter mais motivos a comemorar do que a lamentar. Em nosso campo de atuação, a Atenção Primária à Saúde e a Medicina de Família e Comunidade, alcançaram-se resultados extraordinários nestas duas décadas assim como estão lançadas para o futuro bases para o seu completo desenvolvimento. A ênfase dada à política de universalização com eqüidade irá requerer de todos os profissionais de saúde um crescente e renovado compromisso. Este esforço persistente deve ser destacado como um dos grandes ganhos em nossa sociedade que se reafirma e se aprimora como democrática. Por outro lado isto não se realizará sem esforços e investimentos em ciência e tecnologia, formação de recursos humanos e melhoria da qualidade em todas as suas dimensões, técnica e administrativa. Não se pode ignorar porém que resultados serão alcançados a médio e longo prazos e que só o trabalho árduo e permanente é capaz de realizar as mudanças almejadas. Assim a continuidade das políticas de Estado como a municipalização, a estabilidade dos mecanismos de financiamento, a capacitação de recursos humanos, a prioridade às ações de promoção e prevenção são aquelas que resultarão em melhores resultados em termos de indicadores de saúde. Não há como negar que algumas das questões consideradas problemáticas para o cidadão e usuário do Sistema Único de Saúde retornam diversas vezes à pauta sem que haja uma clareza de como serão resolvidas pelos gestores, profissionais e a sociedade brasileira em geral. É importante persistir com a decisão política por um modelo que garanta a territorialidade da assistência e que esta seja contínua, com vínculo, tal como

    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

    The use of water medications is a common practice in the US swine industry to treat and prevent infections in swine herds with minimal labor and without risk of needle breakage. There are concerns that FDA-approved withdrawal times (WDT) may be inadequate for several water medications when exporting pork products to countries where MRLs (maximum residue limits) are lower than US tolerance levels. In this study, withdrawal intervals (WDI) were estimated for pigs when dosed with tetracycline and sulfamethazine in water. The WDI were calculated using the FDA tolerance method (TLM) and a population-based pharmacokinetic method (PopPK). The estimated WDIs (14-16 days using TLM) were similar to the approved WDT of 15 days for sulfamethazine. However, the PopPK method extended WDIs for both sulfamethazine (19-20 days) and tetracycline (12 days) compared to the currently approved WDTs in the U.S. This study also identified potential differences in WDI between weanling and finisher pigs. In conclusion, the TLM may not always provide adequate WDT for foreign export markets especially when MRLs differ from tolerance levels approved for US markets. However, PopPK methods can provide conservative WDIs in situations with considerable variability in medication exposure such as with administration in water.

    Y-chromosome markers are important tools for studying male-specific gene flow within and between populations, hybridization patterns and kinship. However, their use in non-human mammals is often hampered by the lack of Y-specific polymorphic markers. We identified new male-specific short tandem...... domestic pig populations. European wild boar were characterized by significantly higher levels of haplotype diversity compared to European domestic pigs (HD = 0.904 ± 0.011 and HD = 0.491 ± 0.077 respectively). Relationships among STR haplotypes were investigated by combining them with single nucleotide...... polymorphisms at two linked genes (AMELY and UTY) in a network analysis. A differentiation between wild and domestic populations was observed (FST = 0.229), with commercial breeds sharing no Y haplotype with the sampled wild boar. Similarly, a certain degree of geographic differentiation was observed across...

    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.

    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.

    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.

    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

    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.

    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.

    Salmonella is distributed worldwide and is a pathogen of economic and public health importance. As a multi-host pathogen with a long environmental persistence, it is a suitable model for the study of wildlife-livestock interactions. In this work, we aim to explore the spill-over of Salmonella between free-ranging wild boar and livestock in a protected natural area in NE Spain and the presence of antimicrobial resistance. Salmonella prevalence, serotypes and diversity were compared between wild boars, sympatric cattle and wild boars from cattle-free areas. The effect of age, sex, cattle presence and cattle herd size on Salmonella probability of infection in wild boars was explored by means of Generalized Linear Models and a model selection based on the Akaike's Information Criterion. Prevalence was higher in wild boars co-habiting with cattle (35.67%, CI 95% 28.19-43.70) than in wild boar from cattle-free areas (17.54%, CI 95% 8.74-29.91). Probability of a wild boar being a Salmonella carrier increased with cattle herd size but decreased with the host age. Serotypes Meleagridis, Anatum and Othmarschen were isolated concurrently from cattle and sympatric wild boars. Apart from serotypes shared with cattle, wild boars appear to have their own serotypes, which are also found in wild boars from cattle-free areas (Enteritidis, Mikawasima, 4:b:- and 35:r:z35). Serotype richness (diversity) was higher in wild boars co-habiting with cattle, but evenness was not altered by the introduction of serotypes from cattle. The finding of a S. Mbandaka strain resistant to sulfamethoxazole, streptomycin and chloramphenicol and a S. Enteritidis strain resistant to ciprofloxacin and nalidixic acid in wild boars is cause for public health concern.

  14. Characteristics of wild boar (Sus scrofa habituation to urban areas in the Collserola Natural Park (Barcelona and comparison with other locations

    Cahill, S.

    2012-01-01

    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.

    Using the molecular technique RAMs (Random Amplified Microsatellites, the genetic diversity and the existent genetic relationships were determined among 35 Colombian Creole pigs (Zungo, San Pedreño, Mule Foot and a sample of commercial type individuals. For ty six polymorphic loci were found and the heterozygocity values for the RAM markers fluctuated among 0.22 for CCA and 0.19 for CTand CGA, with 92.30% of polymorphic loci for CCA, 82.3 % for CT and 68.75% for CGA. The heterozygocity was of 0.2016 and the Fst was 0.3058 ±0.0433. The Nei distances tree established a very well defined group formed by the Zungo and San Pedreño breeds, which moved away from the rest of the individuals; the Mule foot pigs and Zungo (CLEM were grouped with the commercial ones, indicating introgression with foreign breeds.

    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.

    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 Considerable importance has been given to nest construction and larval food transport to the nest as a precondition for the eusociality of insects. Most adult hymenopterans feed on liquids, although bees and a few wasps may also feed on pollen. Carrion represents an additional source of protein for some species and they will scavenge for dead animals in the wild. This paper aims at analyzing Hymenoptera visitors on a pig carcass during the process of decomposition, in the summer of 2005 and the winter of 2006 in Brazil, and comparing the results with other studies in the Neotropical region. To our knowledge, this is the first study which described the occurence of Agelaia pallipes, Polybia paulista and Scaptotrigona depilis on decomposing carcasses in southeastern Brazil. It also raises the hypothesis of possible applications of Hymenoptera to achieve more precise PMI estimations, apart from other insects already known as having great importance in such estimates.Considerável importância tem sido dada às construções de ninhos e transporte de alimento larval para o ninho como uma pré-condição para a eusociabilidade dos insetos. Muitos adultos de himenópteros alimentam-se em líquidos, embora as abelhas e poucas vespas podem também se alimentarem de pólen. Carcaças representam uma fonte adicional de proteína para algumas espécies e elas foram uma vez observadas se alimentando de animais mortos na natureza. Este trabalho tem por objetivo analisar Hymenoptera visitantes em carcaças de porcos durante o verão de 2005 e inverno de 2006 no Brasil, ao longo dos estágios de decomposição, comparando com resultados de outros estudos na região Neotropical. Pelo nosso conhecimento, esse é o primeiro estudo que descreveu a ocorrência de Agelaia pallipes, Polybia paulista e Scaptotrigona depilis em carcaças em decomposição no sudeste do Brasil. Isso também aumenta a hipótese na possibilidade de aplicação de Hymenoptera em auxiliar a estimar o IPM de maneira mais precisa, sem levar em conta insetos que já possuem grande importância forense.

    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 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.

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 km(2) 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

Para todos los animales y en especial para aquellos cuyo destino será servir de fuente de alimentos al hombre, se antensifica el compromiso ético de brindarles a lo largo de su vida productiva las mejores condiciones posibles de hábitat, sanidad, manejo, alimentación y cuidados en general. En la actualidad,conceptos de bienestar animal, son cuestión de interés público complejo y multifacético que incluye importantes dimensiones científicas, éticas, económicas y políticas. Por ser un temade importancia creciente en la sociedad, el bienestar animal ha de abordarse sobre bases científicas verdaderas. Las causas de los problemas de bienestar animal, se deben a la percepción errónea acerca de los animales, como seres que no sienten y que por lo tanto, no son capaces de sufrir. Es fácil que se desarrollen actitudes negativas hacia los animales, lo cual se refleja en conductas de negligencia, crueldad o trato irrespetuoso. Los productores,médicos veterinarios, así como la sociedad en general, concientes del cuidado de los animales, saben la importancia de conocer los aspectos del confort de los animales ya que la fisiología, el desarrollo y el comportamiento del animal, son afectados por las malas condiciones ambientales, de producción y de manejo en general.

    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.

    Full Text Available La peste porcina clásica (PPC es una enfermedad viral infectocontagiosa, producida por un virus ARN del género Pestivirus, familia Flaviviridae. En la actualidad es una de las causas de pérdidas económicas en la industria porcina a nivel mundial. En su prevención se han utilizado vacunas vivas atenuadas, empleando la cepa China lapinizada. La Reacción en Cadena de la Polimerasa Reverso Transcriptasa (RT-PCR ha sido uno de los métodos más sensibles aplicado en Medicina Veterinaria para la detección de virus ARN. En el caso del virus de la PPC es muy útil porque el ácido nucleico se puede detectar desde muy temprano en la infección y en periodos más largos en aquellos animales que se recuperan. El objetivo de este estudio fue aplicar la técnica de RT-PCR en tiempo real para la detección de la cepa China lapinizada de la vacuna cubana contra la PPC. Las tonsilas de los cerdos vacunados fueron el órgano más positivo en la detección del ARN del virus vacunal. Los resultados obtenidos evidenciaron una interferencia del virus vacunal en el diagnóstico, siendo el día 12 posvacunación en el que se obtiene una emisión umbral de fluorescencia más bajo.

    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.

    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 Como agente reflexivo de su propia práctica, el profesorado construye creencias pedagógicas sobre el proceso de enseñanza y aprendizaje y, en particular, sobre el rol que sus estudiantes deben asumir en el aprendizaje de un idioma. Este estudio tiene como objetivo identificar las creencias pedagógicas de treinta docentes de inglés de primaria, secundaria y terciaria, en Chile, sobre el rol estudiantil en el proceso didáctico. Un cuestionario, una entrevista semi-estructurada, un diario auto-biográfico y cinco diarios de observación no-participante fueron utilizados para revelar las creencias pedagógicas de sus informantes. Los datos arrojados por los instrumentos fueron analizados con el programa cualitativo ATLASTI, que permitió el levantamiento de tres dimensiones y diez categorías, mediante el uso de la técnica del análisis de contenido semántico. Los resultados muestran que los tres grupos de profesorado declaran que estudiantes que aprenden una lengua extranjera deben tener características personales y académicas relacionadas con la motivación, la participación, la autonomía, entre otras; sin embargo, al interior del aula asumen un rol pasivo y reactivo frente al ambiente de enseñanza altamente estructurado que genera el personal docente. En conclusión, las creencias que cada docente sostiene se alimentan de la teoría y se corroboran o cuestionan en la práctica de aula, a modo de una relación bidireccional entre teoría y práctica, y viceversa.

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.

    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.

    Full Text Available Este artículo estudia la importancia que tiene el orden de nacimiento de los hijos y la falta de recursos económicos en el hogar sobre los niveles de asistencia escolar y la participación en el mercado laboral de la población menor de edad en México. Con base en datos del Módulo de Trabajo Infantil, se estima una serie de modelos probit multivariados bajo distintas especificaciones con el objetivo de minimizar los problemas de endogeneidad de la muestra. El análisis indica que los hijos primogénitos tienen una menor probabilidad de asistir a la escuela y una mayor propensión a participar en el mercado laboral con respecto al resto de sus hermanos. Esta relación se acentúa al enfocarnos en las familias donde el trabajo infantil surge como respuesta a la falta de recursos económicos, lo que sugiere que el resultado es producto de la mayor capacidad de ingresos de los hijos primogénitos.

    Full Text Available Este artigo discute a interlocução do sindicalismo brasileiro com o Sistema Único de Saúde (SUS e os planos e seguros privados de saúde. São ponderadas algumas teses na Saúde Coletiva à luz de estudos mais recentes nas Ciências Sociais sobre o sindicalismo e realizada análise documental para o caso da Central Única dos Trabalhadores (CUT, tomado aqui como referência. Aponta-se a necessidade de considerar os pesos relativos que a ação sindical atribuiu a cada um dos aspectos da relação, SUS e planos privados de saúde, pelas distintas conjunturas do país. O conflito entre trabalhadores e empresas somado ao desemprego e à precarização do trabalho expõe os limites das coberturas assistenciais privadas e impele a representação sindical a pleitear a intervenção estatal. O trabalho refletiu sobre as distintas modalidades de ação sindical na empresa e no Estado. A complexidade dessa dinâmica fez emergir um setor sindical interessado na gestão da previdência complementar e dos planos de saúde e, ao mesmo tempo, recria as circunstâncias e traz novas possibilidades de as organizações sindicais se colocarem na cena política e aglutinar os interesses de amplos segmentos dos trabalhadores para pressionar o Estado na defesa da melhoria do sistema público de saúde.The article intends to discuss the patterns of interlocution between the Brazilian trade unionism, the public health system (SUS and the private health insurance sector.

    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.

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.

    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.

  7. ViSUS: Visualization Streams for Ultimate Scalability

    Pascucci, V

    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

La serotipificación requiere mucho tiempo, trabajo y dinero, actualmente se encuentran herramientas moleculares para realizar una "serotipificación" mediante la genotipificación de toxinas Apx. Así, se evaluaron 60 aislados de App provenientes de nueve empresas porcinas de producción intensiva distribuidas en distintas regiones de Chile, obtenidas desde pulmones de cerdos con lesiones compatibles con pleuroneumonía contagiosa porcina. Las bacterias fueron aisladas mediante los métodos tradicionales y confirmados por API, recolectados durante los años 2007, 2008 y 2009. Los resultados identificaron los genotipos correspondientes sólo a los serotipos 4, 6 y 7, los cuales se describen por primera vez en Chile, siendo el más frecuente el serotipo 7. En las diferentes zonas estudiadas, no existió un serotipo predominante, excepto en las regiones de O'Higgins y del Biobío en las cuales fue más frecuentemente aislado el serotipo 7.

    2014-01-01

    The article examines the process of discursive construction of the 'SUS problem' in reports published in the newspaper Folha de S. Paulo in 2008. Through an online search of the Folha archives, 667 news items were selected and then studied from the perspectives of critical discourse analysis and contributions from social constructionism. In methodological terms, at the text practice level of analysis, the investigation sought to determine what linguistic resources had been used to construct the SUS problem. At the discursive practice level of analysis, it further explored how the newspaper medium and the journalistic style influenced the production of these meanings. The article concludes that as this production constructs the SUS problem, it fosters a limited, negative view of the the Sistema Único de Saúde (Unified Healthcare System, or SUS) based on mistrust and on the notion that it is impossible to improve the system.

  6. 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

  9. 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

    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.

    2003-01-01

    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.

  3. 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)

    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.

    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.

  14. 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

    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.

    Sucrose synthase (SUS) catalyzes the UDP-dependent cleavage of sucrose into UDP-glucose and fructose and has become an important target for improving seed crops via metabolic engineering. A UDP-specific SUS homotetramer composed of 93-kDa subunits was purified to homogeneity from the triacylglyceride-rich endosperm of developing castor oil seeds (COS) and identified as RcSUS1 by mass spectrometry. RcSUS1 transcripts peaked during early development, whereas levels of SUS activity and immunoreactive 93-kDa SUS polypeptides maximized during mid-development, becoming undetectable in fully mature COS. The cytosolic location of the enzyme was established following transient expression of RcSUS1-enhanced YFP in tobacco suspension cells and fluorescence microscopy. Immunological studies using anti-phosphosite-specific antibodies revealed dynamic and high stoichiometric in vivo phosphorylation of RcSUS1 at its conserved Ser-11 residue during COS development. Incorporation of (32)P(i) from [γ-(32)P]ATP into a RcSUS1 peptide substrate, alongside a phosphosite-specific ELISA assay, established the presence of calcium-dependent RcSUS1 (Ser-11) kinase activity. Approximately 10% of RcSUS1 was associated with COS microsomal membranes and was hypophosphorylated relative to the remainder of RcSUS1 that partitioned into the soluble, cytosolic fraction. Elimination of sucrose supply caused by excision of intact pods of developing COS abolished RcSUS1 transcription while triggering the progressive dephosphorylation of RcSUS1 in planta. This did not influence the proportion of RcSUS1 associated with microsomal membranes but instead correlated with a subsequent marked decline in SUS activity and immunoreactive RcSUS1 polypeptides. Phosphorylation at Ser-11 appears to protect RcSUS1 from proteolysis, rather than influence its kinetic properties or partitioning between the soluble cytosol and microsomal membranes.

    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.

    El arpa es un instrumento asociado en el imaginario occidental de los últimos siglos a las mujeres, dentro de la particular política sexual que se ha aplicado al ejercicio de la música en nuestra sociedad patriarcal. Son mujeres sus principales intérpretes, con una representación, en lo que atañe a este cordófono, que supera al resto de los instrumentos musicales.

    Full Text Available San Agustín, Patrimonio Histórico y Cultural de la Humanidad, ubicado en las estribaciones del Macizo Colombiano, al sur del departamento del Huila, atesora en sus tierras uno de los más importantes vestigios arqueológicos del país. Tanto en el Parque Arqueológico como en lugares aledaños al municipio se pueden apreciar las diversas obras esculpidas por esta cultura de la cual aún no se precisan muchos aspectos. Lo que se sabe de ella ha sido producto de las investigaciones hechas desde 1756. Hasta estos parajes ha llegado un buen número de arqueólogos quienes con su aporte ayudaron a estructurar los conocimientos que hoy se tienen de esta cultura y sus representaciones, que giran en torno al culto por los muertos pero que aun así dejan entrever parte de las vivencias de sus pobladores.

  20. SusHi Bento: Beyond NNLO and the heavy-top limit

    CERN Document Server

    Harlander, Robert V; Mantler, Hendrik

    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...

    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

  2. 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

    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

    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.

    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.

    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.

    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.

    Full Text Available O presente estudo descritivo foi realizado em maternidades que prestamatendimento pelo Sistema Único de Saúde (SUS, nas cidades de Guarapuava e Londrina, Estado do Paraná. Dentro do programa de Humanização implantado na Maternidade de Londrina pretendeu-se analisar o atendimento a parturiente quanto à humanização ao partocomparando com a realidade de dois hospitais de Guarapuava onde não existe o programa implantado e assim verificar se os direitos destas parturientes quanto à humanização estão sendo respeitados. 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. In the program implanted in Londrina, the aim was to analyze the assistance to the parturient regarding humanization to the child delivery. This context was then comparedwith the reality in the maternities of two hospitals in Guarapuava, where these practices are not applied. The comparison intended to verify if the rights of these women to humanized delivery are being respected. A half-structured questionnaire was applied to forty women in labor. While comparing these two different realities, it was observed that a few of these rights, advocated by the OMS, were not being respected, especially where the humanization delivery was not a practice.

  18. Adolescentes consumidores de televisión: autopercepciones sobre sus derechos

    Directory of Open Access Journals (Sweden)

    María Ángeles Espinosa Bayal

    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.

  19. A Preliminary Experimental Study of Filmwise and Dropwise Condensation on SUS316 Surface

    Energy Technology Data Exchange (ETDEWEB)

    This paper studied about the cooling characteristic of SUS316 surface as a PCCS heat exchanger. Specifically, filmwise and dropwise condensations on SUS316 surface were compared. The passive safety features against station blackout (SBO) and containment safety became important issue after Fukushima accident. As a result, passive containment cooling system (PCCS) is selected as candidate option for the advanced light water reactors to guarantee integrity of containment. To design efficient heat exchanger of PCCS inside of concrete containment, a number of attempts were studied to compensate the low heat transfer coefficient of condensation in non-condensable gas circumstance. The study in this paper focused on the dropwise condensation to enhance the cooling performance of PCCS heat exchanger. Bare SUS316 surface represented stable dropwise condensation phase over 12 hours of experiment for all experiment condition shown in Table I. Figure 3 shows the previous studies conducted by other researcher with our result. Subcooled temperature versus heat transfer coefficient (HTC) of DWC on various cooling surface with coatings were compared. Figure 4 and 5 shows the condensation HTC of DWC and FWC with different non-condensable gas fractions. The result of DWC with pure steam was well proportional to the power of subcooled temperature. Otherwise, the result with non-condensable gas shows HTC in low subcooled temperature under 5 .deg. C seems to be decreased, but the result was shaded by the high uncertainty. The result of FWC also proportional to power of subcooled temperature regardless of air concentration and well separated by air concentration condition.

    2009-01-01

    Full Text Available Se presentan los resultados de una investigación dirigida a comprender los significados y las respuestas de madres frente al abuso sexual de sus hijas e hijos, para generar un conocimiento útil en la construcción de políticas y programas más pertinentes en la atención de este fenómeno. Es un estudio cualitativo que empleó como método los grupos de discusión con cinco madres de cuatro niñas y un niño, menores de 10 años, víctimas de abuso sexual, quienes asistían a consulta psicológica en dos centros de atención a la familia de la ciudad de Medellín, en el año 2005. Las voces de estas mujeres muestran que el abuso sexual sucede en familias vulnerables desde el punto de vista afectivo, comunicativo y socioeconómico, en las cuales este problema hace parte de su cotidianidad. El abuso sexual constituye una catástrofe que afecta el precario equilibrio socioeconómico y afectivo que estas familias logran construir para hacer frente a sus condiciones de vida angustiantes. En medio de la estigmatización que la sociedad hace de la situación, del silencio, con el cual soportan el trauma, y de un apoyo poco comprensivo y pertinente por parte de las instituciones encargadas de la atención de estas familias, las madres acometen diferentes acciones para hacer frente a su realidad. La reconfiguración de su rol como madres se convierte en un punto de partida clave para la superación del estado de impotencia en el cual quedan sumidas, posterior al abuso sexual de sus hijas(os.

    2012-01-01

    Full Text Available Eduardo Hernández-Pacheco, uno de los geólogos más notables del pasado siglo XX, tuvo un extraordinario interés por el concepto de paisaje, desarrollado en el artículo “El paisaje en general y las características del paisaje hispano”, publicado en 1934 en el Boletín de la Institución Libre de Enseñanza. Con una clara influencia de Alejandro de Humboldt, su visión del paisaje es naturalista. Esto no quiere decir que no aparezcan los seres humanos, con sus ganados, sus cultivos, sus monumentos del pasado, etc., siempre que conserven su carácter tradicional y su relación con el medio en el que se desarrollan. Junto a sus textos, sus fotografías de paisaje forman un legado fundamental para entender su concepción del paisaje y su peso en la historia del paisaje español del siglo XX. El presente artículo se plantea su estudio basado en una de sus obras fundamentales, Fisiografía del Solar Hispano, con especial énfasis en su visión del paisaje a través de la fotografía.

    Full Text Available Introducción: Teniendo en cuenta que el proceso de reparación ósea en los cerdos se muestra en una mayor proximidad entre las variables histológicas estudiadas en comparación con otros modelos biológicos, el presente estudio tenía como objetivo evaluar el proceso histológico de la reparación ósea de osteotomías realizadas en huesos alveolares y extra-alveolar, utilizando instrumentos rotatorios con refrigeración líquida. 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 Este artigo discute a formação do psicólogo em Alagoas e sua relação com o Sistema Único de Saúde (SUS, a partir da análise dos currículos dos quatro cursos de graduação em Psicologia do Estado. Construímos quatro eixos de análise das disciplinas a partir das ementas, conteúdos programáticos e bibliografias: 1 Clínica, psicopatologia e avaliação psicológica; 2 Biomédicas; 3 Interfaces socioculturais; 4 Fundamentos da pesquisa e atuação em Psicologia. Discutimos as formas de abordagem da saúde, problematizando sua relação com o princípio da integralidade do SUS. Os resultados indicam que na abordagem da saúde predominam conteúdos referentes à identificação e classificação de transtornos e psicopatologias, e uma concepção de sujeito individualista e fragmentada, baseada no modelo biomédico. Por sua vez, a abordagem da integralidade, quando presente nos currículos, possui o potencial de nortear mudanças na graduação, vinculando-se a cenários diversificados, como atuação multiprofissional e capacitação profissional generalista.

    Full Text Available The Dakar-Djibouti expedition, led by Marcel Griaule, crossed Africa between 1931 and 1933. One of the participants was Michel Leiris, a young poet who had just severed his relations with the surrealist avantgarde and was in the throes of a personal crisis. This paper is about his experience in that joumey of discovery of himself, of the other and of ethnography. Representation and margination: these are the themes that will endure in L'Afrique fantôme as well as in Leiris' other writings about the Dogon and the Zar cult.

    La Misión Dakar-Yibuti, bajo la dirección de Marcel Griaule, atravesó el continente africano entre 1931 y 1933. En sus filas se encontraba Michel Leiris, joven poeta que acababa de romper con la cúpula surrealista y pasaba por malos tiempos personales. Este artículo registra su experiencia en este viaje de descubrimiento de sí, del otro y de la etnografía. Representación y marginalidad, esos son los elementos que quedarán, tanto en L'Afrique fantôme como en sus otros escritos sobre los dogon y el culto zar.

Si los consumidores tomaran decisiones de abasto en interacción con los agricultores y sus decisiones de producción, sería posible favorecer la reproducción de sistemas de agricultura sustentable. En este artículo se presentan y analizan comentarios de habitantes de la ciudad de México, conseguidos en sesiones de grupos de enfoque, de sus opiniones sobre agricultura, agricultores y prácticas de abasto. Se identificaron tendencias de desconocimiento y desconexión entre consumidores urbanos de clase media y agricultura. Si los consumidores comprendieran que su interacción con los agricultores puede contribuir a la sustentabilidad de la agricultura, en esta se podría integrar la diversidad biológica y social.

    Full Text Available El Derecho Internacional chino tiene una historia larga, pues su primera disposición data del Código Mingli de la Dinastía Ming. 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.

Las mascotas padecen de la pobreza del mismo modo que lo hacen sus dueños. En un País como Bolivia con grandes zonas empobrecidas y extensos barrios periurbanos que se debaten en la miseria, los animales están vulnerables a la desnutrición,enfermedades y sobre todo al abandono.El bienestar animal ha sido definido por la Organización Mundial de Sanidad Animal(OIE como la manera en que los animales se enfrentan con el medio ambiente y que incluye su sanidad, sus percepciones, su estado anímico y otros efectos positivos o negativos que influyen sobre los mecanismos físicos y psíquicos del animal .Lamentablemente en países del llamado “Tercer Mundo” esta definición cae en saco roto.

    2008-01-01

    In the stainless steel 304 (SUS 304) wire drawing process,optimizing the die life and wire tensile strength,which are the larger-the-better quality characteristics (QCH) types,is of main interest.Three control factors,involving reduction ratio,lubricant temperature,and drawing speed,were investigated utilizing L9(34) orthogonal array (OA).The grey relational analysis was conducted for the normalized signal-to-noise (S/N) ratios.The ordinal value of the grey grade was then used to decide optimal factor levels.The anticipated improvements in die life and wire tensile strength were estimated 25.31 h and 22.50 kg/mm2,respectively.To decide the significant factor which had effect on each QCH and predict the average value of each QCH,analysis of variance (ANOVA) was performed for S/N ratio and QCH.Confurmation experiments were then conducted,where a good overlap was noticed between the predicted and confirmation intervals for each QCH.The Hotelling 72 and the sample generalized variance control charts were finally utilized in controlling and monitoring future production.In conclusion,the grey relational analysis utilizing Taguchi method is an effective approach for optimizing the die life and wire tensile strength for SUS wire drawing process.

Para ello se aplicó un cuestionario a una muestra de docentes adscritos en once planteles del estado de Morelos, mediante metodología cuantitativa. Algunos hallazgos encontrados fueron que otorgaban significado al concepto de ciudadanía dentro del marco jurídico-político y que su comprensión del sentido actual del concepto y su construcción son limitadas. A pesar de que los docentes no recibieron capacitación al respecto, aseguran sentirse competentes para incidir en la formación de sus estudiantes.

    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.

    2008-01-01

    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.

    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 falta de información por parte del público en general y de los profesionales de la salud con respecto a la leptospirosis es un problema, debido a que no se toman medidas adecuadas para su prevención y  control. Los animales silvestres y las colecciones zoológicas juegan un papel importante en la posible transmisión y diseminación de la enfermedad, por lo tanto, es relevante que los responsables de la salud y cuidado de éstas especies estén actualizados sobre el tema. Se revisaron los aspectos más relevantes acerca de Leptospira spp. y leptospirosis en colecciones zoológicas y sus potenciales huéspedes, como son: fauna silvestre (en general, roedores sinantrópicos, ardillas y primates no humanos (de manera específica, enfatizando en el rol que cumplen éstas especies y las colecciones zoológicas en la epidemiologia de la leptospirosis. Se realizo una búsqueda de literatura nacional e internacional con el fin de resaltar la importancia de estos espacios y sus animales en la posible diseminación y mantenimiento de la enfermedad en espacios determinados. Finalmente, se muestra como aún falta investigación frente al papel de los animales silvestres en la epidemiología de la leptospirosis; sin embargo, los reportes actuales muestran la importancia de éstas especies en la transmisión y aumento de los casos de leptospirosis.

    Full Text Available Trados TagEditor es la aplicación que SDL Trados ofrece para procesar determinados archivos teniendo en cuenta tanto el texto como el formato. Mediante el uso de etiquetas, el traductor avanza en su labor dándole al texto traducido el mismo formato que trae el archivo original, lo que permite agilizar y reducir los tiempos del proceso integral de la traducción, esto es: preparación, traducción, control de calidad, actualización de la memoria de traducción y diseño. Si bien sus opciones se presentan con botones y menús intuitivos y fáciles de interpretar, el traductor, en general, teme explorar en esta aplicación, y sus funciones están subutilizadas en la mayoría de los casos, por lo que las fallas tanto técnicas como lingüísticas son rasgos típicos del resultado final. ------------------------------------------------ TagEditor - a practical approach to explore its features and make the most of them. Trados TagEditor is the application offered by SDL Trados for the processing of certain file types considering both original text and layout. The use of tags allows the translator to move forward in the translation phase while keeping the format and layout of the source, and to streamline the translation cycle, i.e. to reduce the overall time involved in preparation, translation, QA, TM updates and layout. Although its options are presented as user-friendly and easy-to-understand menus and buttons, translators are generally afraid of exploring this application, something that in most cases results in an underuse of its functions and a subsequent final product that typically contains technical and linguistic errors.

    Full Text Available A aprovação da Política Nacional de Práticas Integrativas e Complementares dá subsídios para implantar a Terapia Comunitária no Sistema Único de Saúde (SUS, visando desenvolver nos profissionais e nas lideranças comunitárias as competências necessárias para lidar com as demandas psicossociais e promover redes de apoio social, ampliando a resolutividade da Atenção Básica. O objetivo deste estudo é descrever a representação social sobre o Terapeuta comunitário elaborada por profissionais de saúde da rede SUS. Participaram 27 profissionais que realizaram a formação em Terapia Comunitária oferecida em 2009 pela Secretaria de Estado da Saúde de Santa Catarina em parceria com o Ministério da Saúde. A coleta de dados utilizou a entrevista individual semidirigida e a análise foi realizada por meio da classificação hierárquica descendente. Os resultados revelam que existe uma representação social dos profissionais sobre o que é ser terapeuta comunitário, entendido como alguém que humaniza as relações interpessoais no setor saúde. No entanto, os profissionais da Atenção Primária são legatários de um modelo de prática grupal menos horizontalizado que os profissionais da Atenção Secundária, nesse trabalho representada pelos Centros de Atenção Psicossocial (CAPS.

    Full Text Available RESUMEN: Sin tratarse de un diezmo propiamente dicho en su concepción, el diezmo serrano se convirtió a lo largo de la Edad Moderna en una exacción añadida a las que pagaban los rebaños trashumantes en sus lugares de origen. Cada año, el producto de la venta o administración directa de las cabezas lanares obtenidas con él, pasaba a engrosar los fondos de las dignidades eclesiásticas en cuyos territorios se encontraban las dehesas que daban acogida a los rebaños durante las etapas invernales. Su análisis descubre los complejos mecanismos desarrollados por la Iglesia para su captación, el operativo mercado que sobre él se montaba y sus beneficiarios, a la vez que permite matizar ciertos aspectos relacionados con la evolución de la trashumancia, imposibles de establecer mediante las cifras plasmadas en los recuentos generales de los ganados.ABSTRACT: Although the tithe of the Sierra was not originally strictly speaking a tithe, throughout the early modern age it became an exaction which was added to those paid by transhumant flocks at their place of origin. Every year, the product of the sale or the direct administration of the sheep obtained by it, increased the funds of ecclesiastical dignataries within whose jurisdiction the "dehesas" which provided pasture for the sheep during the winter months was found. It's analysis brings to light the complex mechanims developed by the Church for its collection, the operative market on wich it was based, and its profits. It also allows us to define certain aspects related to the evolution of transhumance which were impossible to establish through the figures recorded in the general census of cattle.

    Full Text Available La sociedad avanza y a cada problemática, los adelantos científicos y tecnológicos, empleados con iniciativa, voluntad e imaginación dan solución a disímiles contratiempos que enfrenta el hombre en su hacer constructivo por desarrollar más su bienestar social, material y espiritual. El presente trabajo expone una serie de reflexiones en cuanto a lo que ya es un hecho no solo a nivel mundial, sino también en nuestro país, donde determinados elementos de este desarrollo o la introducción de algunos frentes con un fuerte presupuesto de elevación del nivel tecnológico y científico no amparados por un eficiente control administrativo, económico o de otra índole pueden ocasionar a nuestra sociedad daños tanto en lo económico como incluso en el orden político y el ecológico. Esta reflexión se hace tomando el punto de vista de una de las ciencias que desde su modesta trinchera realiza aportes significativos en la lucha contra las violaciones de la legalidad, significando que la Criminalística como se explica en el trabajo conforma una de las ciencias adjuntas al Derecho y como tal desde sus razonamientos y principios propone como puede y debe ser tomada en cuenta en la lucha contra las actividades delictivas cuando estas someten a su servicio el actual saber de la humanidad y a su vez resulta este análisis válido dentro de la indispensable educación ética y útil como una alerta cumpliendo de hecho uno de sus tareas, la prevención.

    Full Text Available Cualquier transacción o relación jurídica comercial implica potencialmente el surgimiento de toda clase de controversias. Dichas disputas adquieren un carácter mucho más delicado cuando los efectos derivados de una resolución que ponga fin a dicha controversia mercantil, ya sea una sentencia [judicial] o laudo [arbitral], busque tener o necesariamente deba tener sus efectos en una jurisdicción distinta a la del foro o cuerpo que la emitió. Las transacciones comerciales originan una compleja red de relaciones que aparecen vinculadas con distintos ordenamientos jurídicos. Determinar qué ordenamiento, así como quién será el juez competente para dirimir el conflicto de naturaleza internacional constituye, en definitiva, el marco dentro del cual opera el derecho internacional privado. Asimismo, las relaciones jurídicas caracterizadas por una complejidad cada vez mayor, derivada de situaciones tales como la intervención de partes de nacionalidades distintas, demandan una solución jurídica y medios eficaces para resolver controversias por medios distintos a los jurisdiccionales. Es bajo ese panorama que surge la Convención de Roma sobre la Ley Aplicable a las Obligaciones Contractuales de 1980, como un instrumento dentro de la Unión Europea que busca, entre otros aspectos que quedan fuera del ámbito de estudio del presente, solucionar los conflictos de leyes comunitarios introduciendo para ello un orden novedoso en la aplicación de los principios convencionales del Derecho Internacional Privado. ¿Cuáles son dichas aportaciones?, pero cuáles son también por el otro lado sus limitaciones, es el espacio de análisis del presente trabajo.

  20. Detección de cianobacterias y sus toxinas. Una revisión

    Full Text Available La creciente eutrofización de los ambientes acuáticos favorece el crecimiento masivo (blooms de algas, y poblaciones de cianobacterias, capaces de producir potentes toxinas con graves repercusiones en la salud pública y en la sanidad animal. Más del 50% de las proliferaciones masivas de cianobacterias son tóxicas. Dentro de una misma especie de cianobacteria, existen cepas que producen toxinas y otras que no las producen. Se hace necesario disponer de métodos que permitan detectar y cuantificar cianobacterias y sus toxinas. Los tradicionales bioensayos en ratón para conocer la toxicidad de una muestra sospechosa, se van sustituyendo por otros bioensayos y diversos métodos in vitro que están demostrando ser eficaces. El avance experimentado en las técnicas inmunológicas y enzimáticas ha facilitado la detección rápida de toxinas mediante el empleo de kits comerciales y no comerciales. Uno de los campos más prometedores de investigación, consiste en la determinación de las secuencias genéticas que diferencian géneros incluso cepas tóxicas, así como otras que codifican para la síntesis de toxinas; métodos que permitirán prever el desarrollo de cianobacterias o sus toxinas. El control y seguimiento de los desarrollos masivos de cianobacterias, es muy importante para garantizar la calidad del agua. El reconocimiento de los factores ambientales que influyen o desencadenan la aparición de blooms, es otro factor fundamental para la prevención y el control.
