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.

    1992-04-01

    Fifty-seven wild boars (Sus scrofa) from protected regions of Iran were examined for helminths. Sixteen species of helminths were collected; there were ten nematodes, one acanthocephalan, two trematodes and three larval cestodes. New host and distribution records were established for all helminths except of Taenia solium cysticerci. Wild boar shared nine of these helminths with domestic pigs, six with ruminants and three with human beings in Iran. Metastrongylus pudendotectus and M. salmi are reported for the first time from Iran.

    2013-06-01

    The Indian wild pig (Sus scrofa cristatus) is a protected species and listed in the Indian Wildlife (Protection) Act, 1972. The wild pig is often hunted illegally and sold in market as meat warranting punishment under law. To avoid confusion in identification of these two subspecies during wildlife forensic examinations, we describe genetic differentiation of Indian wild and domestic pigs using a molecular technique. Analysis of sequence generated from the partial fragment (421bp) of mitochondrial DNA (mtDNA) cytochrome b (Cyt b) gene exhibited unambiguous (>3%) genetic variation between Indian wild and domestic pigs. We observed nine forensically informative nucleotide sequence (FINS) variations between Indian wild and domestic pigs. The overall genetic variation described in this study is helpful in forensic identification of the biological samples of wild and domestic pigs. It also helped in differentiating the Indian wild pig from other wild pig races. This study indicates that domestic pigs in India are not descendent of the Indian wild pig, however; they are closer to the other wild pig races found in Asia and Europe.

    2015-07-01

    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. Copyright © 2015 Elsevier Ltd.

    2011-07-01

    We used serology to estimate the prevalence of exposure to chlamydiae in Italian populations of wild boars (Sus scrofa). Sera from 173 hunter-killed wild boars harvested during the 2006-2009 hunting seasons in three Italian regions were tested for antibodies to Chlamydia suis, Chlamydophila pecorum, Chlamydophila abortus, and Chlamydophila psittaci by the microimmunofluorescence test. Antibody titers to chlamydiae ≥ 1:32 were detected in 110 of the 173 samples tested (63.6%). Specific reactivity could be assessed only in 44 sera with antibody titers to C. suis that were two- to threefold higher than antibody titers against the other chlamydial species; the other 66 sera had similar reactivity against all the chlamydia species tested. Antibody to C. suis was detected in sera from wild boar populations with rare or no known contact with domestic pigs. These results suggest that the wild boar could be a chlamydia reservoir and may acquire chlamydiae independent of contacts with the domestic pig.

    Full Text Available The comparative study of Sus scrofa muscle tissue with different defects of quality was carried out. Such analysis methods as determination of water-binding capacity (WBC and pH values, microstructural studies, proteome methods, mass spectrometric methods, high performance liquid chromatography (HPLC and determine the concentration of cathepsin D, calpain 3 and myoglobin were applied in current study. DFD meat was characterized by high pH (6.2 and WBC (93.18%, while PSE - low pH (5.5 and WBC (79.19%. pH and WBC values in NOR pork was medium and averaged 5.9 and 92.05%, respectively. Microstructural studies revealed that fiber in exudative pork was the least and averaged 39.7 µm, normal pork was characterized by diameter of muscle of 45.5 µm, while DFD pork ‑ 48.3 µm. Protein composition of Sus scrofa muscle tissues were also investigated by one-dimensional and two-dimensional electrophoresis. 6 protein fractions were identified by mass spectrometry and confirmed as potential biomarkers of pork quality defects in meat and processes meat product. It also has been shown that PSE pork contains 8 characteristic peptides, NOR - 14, DFD - 18. Cathepsin D, calpain 3 and myoglobin content were measured in pork of different categories. The highest content of cathepsin D, calpain 3 and myoglobin was noticed in PSE pork and averaged 82.16 ±3.30 ng.mL-1; 1.280 ±0.082 ng.mL-1; 3.973 ±0.506 ng.mL-1, respectively. Since the study was carried out on samples of meat 24 hours after slaughter, this work had the prospect to further study of meat with different defects of quality during long-term autolysis.

    Full Text Available The article presents the results of autolytic processes impact on the protein-peptide profile of Bos taurus and Sus scrofa cardiac muscle and aorta. The results of tissue-specific protein identification are also presented as well as the effect of autolysis. Apolipoprotein A-1 involved in the formation of high-density lipoproteins, peroxiredoxin-1 involved in the suppression of oxidative stress, galectin-1 induced apoptosis of T-lymphocytes, as well as number of heat shock proteins with molecular weight less than 30 kDa were identified in Sus scrofa aorta tissue. It was discovered that functional proteins with molecular weight less than 30 kDa are retained during the freezing process, but destroyed under the action of autolytic enzymes.

    Edge-effects greatly extend the area of tropical forests degraded through human activities. At Pasoh, Peninsular Malaysia, it has been suggested that soil disturbance by highly abundant wild pigs (Sus scrofa), which feed in adjacent Oil Palm plantations, may have mediated the invasion of Clidemia hirta (Melastomataceae) into the diverse tropical lowland rain forest. To investigate this hypothesis, we established three 1 km transects from the forest/Oil Palm plantation boundary into the forest...

    Full Text Available Thirty pairs of kidneys of wild boar (Sus scrofa were studied from adult males, with permission from the Brazilian Institute of the Environment (Process nº 02001.003237/05, aiming to characterize the vasculature and anatomic surgical segmentation. The arteries of these kidneys were injected with red pigment and subsequently submitted to acid corrosion in order to identify the renal arterial vascular pattern, particularly its divisions and distribution. The results reveal the sectorial branches of the renal arteries, two in number (cranial and caudal; the sectorial arteries provide the segmentary branches to the dorsal and ventral portions of the kidney; in the right kidney, the segmentary branches are 2-6 in the cranial sector and 3-7 in the caudal sector. In the right kidney, the segmentary branches are 3-7 and 2-7 in the same respective sectors; the vascular arterial symmetry (25% between the right and left kidney in the animals is evident. There are 3 arterial anatomic surgical segments on both kidneys. On the basis of the distribution of the sectorial and segmentary arteries, it is possible to accomplish setorectomy and segmentectomy on the kidneys of the wild boar, with functional aspects such as species preservation and animal experimental modeling.

    2018-01-01

    Feral pigs (Sus scrofa L.) are perhaps the most abundant, widespread, and economically significant large introduced vertebrate across the Pacific island region. Unlike many other nonnative invasive species, feral pigs have both cultural and recreational importance in the region, complicating their management. Today, Pacific island feral pigs are a mixture of several strains of domestic swine, Asiatic wild boar, and European wild boar. Due to their generalist diet and rooting behavior, feral pigs alter soils and watersheds and negatively impact native and nonnative flora and fauna. As a result, feral pigs have played a role in the extinction of several species of plants and animals on Pacific islands and have negative effects on both ecotourism and agricultural industries in the region. Despite numerous published studies on feral pigs in the Pacific island region, of which the majority include systematic analyses of original empirical data, some fundamental aspects of feral pig ecology remain poorly characterized, at least partly due to the remote and inaccessible environments that they often inhabit. To address these knowledge gaps, effort should be made to integrate research conducted outside the Pacific island region into local management strategies. This review summarizes the origins, history, ecology, environmental effects, and current management of feral pigs in the Pacific island region; integrates regional scientific findings with those of other insular and continental systems; and identifies current knowledge gaps requiring further research to inform the ecology and management of this impactful invasive species.

    Bovine tuberculosis is a chronic disease of cattle ( Bos taurus ) caused by the bacterium Mycobacterium bovis . Efforts have been made in the US to eradicate the disease in cattle, but spillover into wildlife and subsequent spillback have impeded progress in some states. In particular, infection in white-tailed deer ( Odocoileus virginianus ) has been followed by infection in cattle in some Midwestern states. Infection has also been documented in feral swine ( Sus scrofa ) on the Hawaiian island of Molokai and in various European countries, but no large-scale survey of antibody exposure to the bacteria has been conducted in feral swine in the US. We tested 488 sera from feral swine collected near previously documented outbreaks of bovine tuberculosis in cattle and captive cervids, in addition to 2,237 feral swine sera collected across the US from 1 October 2013 to 30 September 2014. While all but one of the samples were antibody negative, the results are important for establishing baseline negative data since feral swine are capable reservoirs and could be implicated in future outbreaks of the disease.

    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.

    2017-03-01

    Full Text Available The objective of this investigation was to estimate the occurrence of infections by the three zoonotic bacteria Anaplasma phagocytophilum (A. phagocytophilum, Borrelia burgdorferi sensu lato (B. burgdorferi s.l. and Coxiella burnetii in wild boars (Sus scrofa in Central Italy. The spleen samples from 100 hunted wild boars were submitted to DNA extraction and PCR assays were carried out to detect the three agents. One (1% animal was positive for A. phagocytophilum, and three (3% for B. burgdorferi s.l. No positive reactions were observed for Coxiella burnetii. Wild boars did not seem to play an important role in the epidemiology of the three investigated agents. However, the detection of A. phagocytophilum and B. burgdorferi s.l. in the spleen of the tested animals showed that wild boars can harbor these pathogens, thus ticked that feeding on infected wild boars are likely to become infected, too, which represents a source of infection for other animals and humans. This is the first detection of A. phagocytophilum in wild boars in Italy.

    :  Feral swine ( Sus scrofa) are a pathogen reservoir for pseudorabies virus (PrV). The virus can be fatal to wildlife and contributes to economic losses in the swine industry worldwide. National surveillance efforts in the US use serology to detect PrV-specific antibodies in feral swine populations, but PrV exposure is not a direct indicator of pathogen transmission among conspecifics or to non-suid wildlife species. We measured antibody production and the presence of PrV DNA in four tissue types from feral swine populations of Florida, US. We sampled blood, nasal, oral, and genital swabs from 551 individuals at 39 sites during 2014-16. Of the animals tested for antibody production, 224 of 436 (51%) feral swine were antibody positive while 38 of 549 feral swine (7%) tested for viral shedding were quantitative polymerase chain reaction (qPCR)-positive for PrV. The detection of PrV DNA across all the collected sample types (blood, nasal, oral, and genital [vaginal] swabs) suggested viral shedding via direct (oronasal or venereal), and potentially indirect (through carcass consumption), routes of transmission among infected and susceptible animals. Fourteen of 212 seronegative feral swine were qPCR-positive, indicating 7% false negatives in the serologic assay. Our findings suggest that serology may underestimate the actual infection risk posed by feral swine to other species and that feral swine populations in Florida are capable of shedding the virus through multiple routes.

    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.

    Corynebacterium pseudotuberculosis is the etiologic agent of caseous lymphadenitis, a common disease in small ruminant populations throughout the world and responsible for a significant economic impact for producers. To our knowledge, this is the first characterization of C. pseudotuberculosis from caseous lymphadenitis lesions in Black Alentejano pig (Sus scrofa domesticus). In this study, phenotypic and genotypic identification methods allocated the swine isolates in C. pseudotuberculosis biovar ovis. The vast majority of the isolates were able to produce phospholipase D and were susceptible to most of the antimicrobial compounds tested. Macrorestriction patterns obtained by Pulsed Field Gel Electrophoresis (PFGE) grouped the C. pseudotuberculosis in two clusters with a high similarity index, which reveals their clonal relatedness. Furthermore, swine isolates were compared with C. pseudotuberculosis from caprines and PFGE patterns also showed high similarity, suggesting the prevalence of dominant clones and a potential cross-dissemination between these two animal hosts. This work represents the first report of Corynebacterium pseudotuberculosis from caseous lymphadenitis lesions in Black Alentejano pig and alerts for the importance of the establishment of suitable control and sanitary management practices to control the infection and avoid further dissemination of this important pathogen to other animal hosts.

    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.

    Tuberculosis, a chronic progressive disease, has been reported in bovine, swine, and primate species. Here, we report the first case of Mycobacterium tuberculosis infection in a Korean wild boar ( Sus scrofa coreanus). The owners this domesticated boar brought it to the Gyeongbuk Veterinary Service Laboratory in Korea after it was found dead and severely emaciated. Demarcated yellowish white nodules were found around the larynx and retropharyngeal lymph node during necropsy. The lungs had diffuse fibrinous pleuritis, severe congestion, and scattered nodules. More nodules were found in the spleen. Tuberculosis is characterized by massive macrophage infiltration and central caseous necrosis; both characteristics were found in the lungs. Histopathologic examination revealed that the alveolar lumen had marked fibrosis and exudates. Examination of the fluid revealed extensive macrophage permeation. To confirm a Mycobacterium infection, PCR was performed using two primer sets specific to the rpoB gene of Mycobacterium; Mycobacterium was detected in the lungs and spleen. To identify the species of Mycobacterium, immunohistochemical evaluation was performed using antibodies against Mycobacterium tuberculosis and Mycobacterium bovis . The results revealed immunoreactivity against M. tuberculosis but not against M. bovis . The consumption of undercooked or raw meat from game animals may expose humans and other animals to sylvatic infection. Consequently, Koreans who ingest wild boar may be at risk of a tuberculosis infection. To reduce the risk of foodborne infection and maintain public health, continuous monitoring and control strategies are required.

    The number and spatial distribution of wild boars (Sus scrofa) has increased remarkably in Sweden as well as in other European countries. To understand the population dynamics of the wild boar, knowledge of its reproductive period, oestrus cycle and reproductive success is essential. The aim of this study was therefore to describe the seasonal reproductive pattern and reproductive potential of a wild boar population in Sweden. The study was based on findings from macroscopic examinations of the reproductive organs from 575 hunter-harvested female wild boars (>30 kg body weight). Samples were collected between December 2011 and December 2015 in the southern and middle parts of Sweden. The age of the sampled animals was determined and dressed weight was noted. The stage of the reproductive cycle was defined according to ovarian structures and in relation to the appearance of/and findings in the uterus. The crown-rump length (CRL) of the embryos/foetuses was used to calculate the oestrus/mating month and month for the expected farrowing. The macroscopic examination revealed a seasonal variation of reproductive stages, although cyclic and pregnant females were found in all seasons. Moreover, the estimated oestrus/mating and farrowing months based on the CRL showed that mating and farrowing may occur 'off-season'. The average litter size (no. of embryos or foetuses) per pregnant female was 5.4. Sow weight and age had significant effect on both the reproductive potential (ovulation rate and litter size) and pregnancy rate, respectively. The reproductive potential in the studied wild boar population was high compared to studies from other countries and farrowing may occur 'off-season'. This suggests that the environmental conditions in Sweden, including supplemental feeding, are favourable for wild boar reproduction.

    A novel rhabdovirus was isolated from the serum of a healthy Japanese wild boar (Sus scrofa leucomystax) and identified using the rapid determination system for viral nucleic acid sequences (RDV), next-generation sequencing, and electron microscopy. The virus was tentatively named wild boar rhabdovirus 1 (WBRV1). Phylogenetic analysis of the entire genome sequence indicated that WBRV1 is closely related to Tupaia rhabdovirus (TRV), which was isolated from cultured cells of hepatocellular carcinoma tissue of tree shrew. TRV has not been assigned to any genus of Rhabdoviridae till date. Analysis of the L gene indicated that WBRV1 belongs to the genus Vesiculovirus. These observations suggest that both TRV and WBRV1 belong to a new genus of Rhabdoviridae. Next-generation genome sequencing of WBRV1 revealed 5 open reading frames of 1329, 765, 627, 1629, and 6336 bases in length. The WBRV1 gene sequences are similar to those of other rhabdoviruses. Epizootiological analysis of a population of wild boars in Wakayama prefecture in Japan indicated that 6.5% were positive for the WBRV1 gene and 52% were positive for WBRV1-neutralizing antibodies. Furthermore, such viral neutralizing antibodies were found in domestic pigs in another prefecture. WBRV1 was inoculated intranasally and intraperitoneally into SCID and BALB/c mice and viral RNA was detected in SCID mice, suggesting that WBRV1 can replicate in immunocompromised mice. These results indicate this novel virus is endemic in wild animals and livestock in Japan. Copyright © 2015 Elsevier B.V. All rights reserved.

    Over the last 20 years, oral vaccination implementing a live attenuated vaccine has been experimented in Europe in order to control classical swine fever (CSF) in Wild Boar (Sus scrofa sp.). This has generally led to an enhanced seroprevalence and a decreased viroprevalence at the scale of the whole vaccinated populations, but no quantitative analysis has demonstrated the protective effect of preventive vaccination or intensive baiting. In the present paper we conducted a retrospective analysis at the scale of the municipality, taking into account the local dynamics and possible covariates of infection to test the effect of preventive vaccination and of the baiting effort. To be efficient, vaccination was expected to increase seroprevalence above the level considered as suitable for preventing disease invasion (40-60%) independently of infection, to protect free areas from disease invasion or contribute to control subsequent disease intensity and duration. We also hypothesized that a better baiting effort would be correlated with an improvement of immunisation and disease control. In uninfected municipalities, seroprevalence increased up to 40% after 1 year, i.e., three vaccination campaigns. We observed a significant protective effect of preventive vaccination, especially within municipalities that had been vaccinated at least 1 year before disease emergence and where virus detection did not last more than one quarter. On the other hand, we did not detect a significant effect of the baiting effort on local seroprevalence or disease dynamics, suggesting that the baiting system could be improved. We discuss these results regarding the improvement of management measures and further research perspective. Copyright 2009 Elsevier B.V. All rights reserved.

  17. Three-Dimensional Force Measurements During Rapid Palatal Expansion in Sus scrofa

    Full Text Available Rapid palatal expansion is an orthodontic procedure widely used to correct the maxillary arch. However, its outcome is significantly influenced by factors that show a high degree of variability amongst patients. The traditional treatment methodology is based on an intuitive and heuristic treatment approach because the forces applied in the three dimensions are indeterminate. To enable optimal and individualized treatment, it is essential to measure the three-dimensional (3D forces and displacements created by the expander. This paper proposes a method for performing these 3D measurements using a single embedded strain sensor, combining experimental measurements of strain in the palatal expander with 3D finite element analysis (FEA. The method is demonstrated using the maxillary jaw from a freshly euthanized pig (Sus scrofa and a hyrax-design rapid palatal expander (RPE appliance with integrated strain gage. The strain gage measurements are recorded using a computer interface, following which the expansion forces and extent of expansion are estimated by FEA. A total activation of 2.0 mm results in peak total force of about 100 N—almost entirely along the direction of expansion. The results also indicate that more than 85% of the input activation is immediately transferred to the palate and/or teeth. These studies demonstrate a method for assessing and individualizing expansion magnitudes and forces during orthopedic expansion of the maxilla. This provides the basis for further development of smart orthodontic appliances that provide real-time readouts of forces and movements, which will allow personalized, optimal treatment.

    Full Text Available Habitat use by wild boar Sus scrofaz was examined during a three-year period in Moncayo Nature Park, a protected mountain area in the Iberian mountain system, Spain. Tracking indirect signs of activity was used to collect data on the species occurrence, according to vegetation type, topography, hunting activity, and season. The data were analysed using binary logistic regression. Habitat used by wild boar differed according seasons, management practices, and vegetation. Main selected habitats were at medium elevations (1,101-1,600 m in areas dominated by holm oak (Quercus ilex, beech (Fagus sylvatica and oak woods of Q. robur, Q. petraea and Q. pyrenaica. Non-hunting areas were selected over hunting areas. We found a seasonal variation in the habitat use of wild boar, with areas dominated by holm oak being used disproportionately in spring, and areas at medium elevations selected only during summer. The results also support the view that non-hunting areas provide a refuge for this species inside the protected area.Estudiamos el uso del hábitat por parte del jabalí Sus scrofa a lo largo de tres años en el Parque Natural del Moncayo, un área protegida de montaña en el Sistema Ibérico, España.

    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

    Since 1995 the population of wild ungulates increased significantly in the "Parco provinciale dei Monti Livornesi" (Livorno, Tuscany, Central Italy). We studied the intestinal macroparasites of two hosts, the wild boar (Sus scrofa) and the mouflon (Ovis gmelini musimon). In the case of wild boars we found a dominant parasite species, Globocephalus urosubulatus. For this parasite the frequency distribution of the number of parasites per host agrees with a negative binomial distribution. There is not a significant correlation between the age of the animals and the parasitosis. Furthermore the mean parasite burden of male and female wild boars does not differ significantly. In the case of mouflons we found a dominant parasite species Nematodirus filicollis with Trichuris ovis as codominant species.

    Full Text Available Abstract The following study contains and analyses data about the wild boar (Sus scrofa hunted in the Como and Varese provinces from October 1993 to January 1994. These populations have been formed from individuals which have been illegally introduced continuously since 1978 in the Varese province and since the mid 80s in the Como province. Some of them have also come from the neighbouring Switzerland. Biometric analyses were carried out on 189 specimens, and were divided into age and sex classes. We considered 8 measurements for some external morphological characteristics and 28 for the skull structure. For each specimen the age class was evaluated by tooth growth analysis. The possible presence of fetuses in every female was also checked. The data collected by the Veterinary Service (U.S.S.L. enabled us to identify the main diseases of the studied populations. Frequent cases of tuberculosis were observed.

    Full Text Available Aim: Wild boars, Sus scrofa, are potential reservoirs of many zoonotic diseases, and there are a possibility of transmission of the zoonotic diseases from these animals to humans and also domestic animals. This study aimed to evaluate the protozoan contamination of wild boars in the Persian Gulf’s coastal area (Bushehr Province, southwestern Iran. Materials and Methods: A total of 25 crossbred boars were collected during a course of vertebrate pest control in Bushehr province, in 2013. Samples were collected from the gastrointestinal tracts of each boar in 5% formalin, Bouin’s solution, sodium acetate-acetic acid-formalin, and polyvinyl alcohol fixatives. Fixed stool smears examined by trichrome and Ziehl–Neelsen staining. Results: Each of the 25 wild boars was infected with at least one of the intestinal protozoans. The rate of contamination with intestinal protozoan was 64% for Balantidium coli, 76% for Iodamoeba sp., 52% for Entamoeba polecki, 44% for Blastocystis sp. and 8% for Chilomastix sp. No intestinal coccidian was detected in studied boars when the stool samples were evaluated by Ziehl–Neelsen staining method. Conclusion: Findings of this study demonstrated that wild boars in the Persian Gulf coastal area are contaminated by many protozoans, including zoonotic protozoan, which poses a potential risk to locals as well as the domestic animals of the area.

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

    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. Copyright © 2015 Elsevier Inc.

    In South America, wild populations of peccaries coexist with domestic and feral pigs, with poorly understood consequences. We captured 58 collared peccaries ( Pecari tajacu) and 15 feral pigs ( Sus scrofa) in locations of Colombia where coexistence of these species is known. Blood samples were tested for antibodies against four viral agents, classical swine fever virus (CSFV), Aujeszky's disease virus (ADV), porcine circovirus (PCV-2), and vesicular stomatitis virus (New Jersey and Indiana subtypes) and two bacterial agents, Brucella spp. and six serovars of Leptospira interrogans. The prevalence of CSFV was 5% (3/58) in collared peccaries and 7% (1/15) in feral pigs. The prevalence of PCV-2 was 7% (1/15) in collared peccaries and 67% (2/3) in feral pigs. Vesicular stomatitis prevalence was 33% (8/24) in collared peccaries and 67% (4/6) in feral pigs. Leptospira prevalence was 78% (39/50) in collared peccary and 100% (8/8) in feral pigs; bratislava, grippotyphosa, icterohaemorrhagiae, and pomona were the most frequent serovars. Also, the only white-lipped peccary ( Tayassu pecari) sampled was positive for L. interrogans serovar bratislava and for vesicular stomatitis virus, New Jersey strain. No samples were positive for ADV or Brucella. The seroprevalence of antibodies against L. interrogans was similar to that observed in other studies. Icterohaemorrhagiae appears to be a common serovar among in situ and ex situ peccary populations. Positive antibodies against PVC-2 represent a novel report of exposure to this pathogen in Colombian peccaries. Our results indicate the possible transmission of various pathogens, important for pig farms, in the studied pig and peccaries.

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

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

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

    Full Text Available Abstract Wild boar (Sus scrofa spreading and crop damage in an area of western Prealps We analysed the agricultural damage reports from 1986 to 1996 to evidence the wild boar distribution in Biella province and the pattern of land occupancy. These reports were yearly divided and mapped for the single municipalities to obtain a picture of the range variations in the time. From the same reports we calculated three indexes of the importance of the Wild boar damages: the damaged surface for each municipality, its percentage value on the surface of each municipality and the occurrence of damages for each municipality. During the study period, we observed a dramatic increase of the number of municipalities affected by wild boar damages and of the species range. The yearly damaged surface grew over 25 times too. The Discriminant Function Analysis carried out between damaged and undamaged municipalities correctly classified 78,1% of total cases by three variables: mixed woods, pastures and dry crops, the second one being the most important. The Multiple Regression Analysis of the damages occurrence vs. habitat variables explained 77,3% of independent variable variance by five variables, which entered the model. The trend analysis, carried out by the seasonal regression, using the surface and the occurrence of damages, evidenced a marked seasonality of the damages and a stability trend, after an initial positive trend. Riassunto Per evidenziare la distribuzione del Cinghiale in provincia di Biella e le modalità d'occupazione del territorio nel corso degli anni, sono state utilizzate le denunce dei danni pervenute all Amministrazione provinciale dal 1986 al 1996.

    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.

    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.

    Bovine tuberculosis (bTB) is a (re-)emerging disease in European countries, including Switzerland. This study assesses the seroprevalence of infection with Mycobacterium bovis and closely related agents in wild boar (Sus scrofa) in Switzerland, because wild boar are potential maintenance hosts of these pathogens. The study employs harmonised laboratory methods to facilitate comparison with the situation in other countries. Eighteen out of 743 blood samples tested seropositive (2.4%, CI: 1.5-3.9%) by ELISA, and the results for 61 animals previously assessed using culture and PCR indicated that this serological test was not 100% specific for M. bovis, cross-reacting with M. microti. Nevertheless, serology appears to be an appropriate test methodology in the harmonisation of wild boar testing throughout Europe. In accordance with previous findings, the low seroprevalence found in wild boar suggests wildlife is an unlikely source of the M. bovis infections recently detected in cattle in Switzerland. This finding contrasts with the epidemiological situation pertaining in southern Spain. Copyright © 2014 Elsevier Ltd. All rights reserved.

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

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.

    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. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Introduction and objective. The aims of the study were: 1 to detect antibodies against T[i]oxoplasma gondii[/i] from wild boar meat; 1 establish seroprevalence of toxoplasmosis in the wild boar population; 3 establish risk factors concerned in higher possible seroprevalence; 4 to estimate the usefulness of meat juice for detection of [i]T. gondii[/i] antibodies in wild boar. Material and methods. Diaphragm meat juice samples from 656 wild boar ([i]Sus scrofa[/i] were collected during the hunting seasons between September 2008 – October 2010 from 9 districts of the Czech Republic. The samples were stratified per age category into 2 groups: piglets (n = 279 and yearlings together with adults (n = 377. The in-house ELISA test was used for the detection of antibodies against [i]T. gondii [/i]from the meat juice samples. Results. Antibodies against [i]T. gondii [/i]were detected by in-house ELISA in 260 of 656 wild boars (40% with 26% prevalence in piglets (72/279 and 50% prevalence in yearlings and adults (188/377. The district total seroprevalences ranged between 32% – 59%, with a significantly higher prevalence in the district of Havlíčkův Brod (59%. Statistically significant differences (p-value < 0.05 were found between 2 age categories, and between 9 districts, with a significant variability in the district of Havlíčkův Brod. Seroprevalence correlated positively with farm density, but without any statistical significance. Conclusion. The obtained results indicate that consumption of raw or undercooked meat from wild boars can carry an important risk of toxoplasma infection. Post mortem detection of antibodies in meat juice samples using ELISA is a useful alternative to blood serum examination. In addition, a diaphragm sample has been well-proven as a matrix sample for the contemporaneous diagnostics of trichinellosis and toxoplasmosis.

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

    Directory of Open Access Journals (Sweden)

    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.

    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.

    Full Text Available The aim of the study was to analyse the fatty acid profile of wild boar (Sus scrofa meat. The samples were obtained from the mountain Tríbeč (southwest part of the Slovak Republic. A total of 36 samples in 3 age categories of meat were analysed. The effect of age on the intramuscular (IMF fat content was analysed. The highest (P < 0.05 IMF content was found in the samples from the youngest animals (18.07%, the lowest (P < 0.05 in the sub-adult animals. Significant (P < 0.05 differences were found in palmitic acid (C16:0. Significant decrease of heptadecanoic acid (C17:0 as an effect of age was analysed in the samples. Of the important fatty acids, the most abundant in all age categories of wild boar were oleic (C18:1 cis 9, palmitic (C16:0, and linolelaidic acid (C18:2 cis n6. Differences in the content of mentioned acids were significant (P < 0.05. In α-linolenic and γ-linoleic acids, non-significant (P > 0.05 differences were detected. Significant differences (P < 0.05 between age categories were found in cis-11-eicosenoic (C20:1 n9 and cis-11,14-eicosadienoic acids (C20:2 n6. Significant differences (P < 0.05 were found in PUFA (polyunsaturated fatty acids, MUFA (monounsaturated fatty acids, and SFA (saturated fatty acids concentrations. The highest PUFA content was typical for the samples from the oldest animals, MUFA from the sub-adults, and SFA from the youngest wild boar. More significant results were observed in the normalized data with the factor component scores. The wild boar fatty acid profile is significantly affected by age.

    Full Text Available In spring 2012, osteological material was collected at the “Gornja Šuma” site (site no. 47, located in the territory of Novi Sad, and it was dated to the early 9th century. The withers heights of pig - Sus scrofa domestica, domestic cow - Bos taurus and sheep - Ovis aries, as the three most dominant species at this archaeological site, were analysed based on the length of bones and according to various authors [Boessneck 1956; Zalkin 1960; Matolcsi 1970; Teichert 1975]. It was determined that in these three species the withers heights mostly corresponded to the data from the Middle Ages.

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

    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.

  15. Investigating the role of free-ranging wild boar (Sus scrofa in the re-emergence of enzootic pneumonia in domestic pig herds: a pathological, prevalence and risk-factor study.

    Directory of Open Access Journals (Sweden)

    Mainity Batista Linhares

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

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

O experimento foi realizado em uma área de mata, localizada nas dependências do Instituto de Pesquisa Museu Emílio Goeldi, em Belém-Pa. Foi utilizado como isca um suíno (Sus scrofa L. inteiro (com vísceras, de 14,5 Kg, recém abatido. Este foi exposto sob uma armadilha do tipo suspensa modificada, adequada à coletas de insetos adultos, sendo que também foram coletadas larvas e pupas, diretamente na carcaça. A ocorrência dos insetos adultos e de seus estágios larvais foi correlacionada com o tempo de morte do animal, a fim de possibilitar futuras inferências de tempo de morte com base na presença e dispersão destes insetos. O tempo de decomposição e a duração de cada estágio de decomposição foram registrados, tendo sido afetados provavelmente pelo tamanho da carcaça e pela estação do ano. Diferenças quanto ao padrão de sucessão não foram observadas

    Full Text Available La obra de Augusto Boal Teatro del Oprimido se suele situar entre las aportaciones más transcendentales del teatro del siglo XX, en tanto sus dictados teóricos y sus propuestas metodológicas y prácticas han calado en ámbitos de la educación social y teatral relacionados con el desarrollo de la democracia cultural. Pasados cuarenta años desde sus primeras experiencias, en este trabajo se propone una genealogía del teatro del oprimido a partir de una lectura crítica de sus textos fundacionales y de alguna experiencia considerada paradigmática en su desarrollo, para mostrar su naturaleza, aportes, fortalezas y debilidades. Igualmente se muestra el tránsito entre una dimensión más educativa y teatral y otra más centrada en la terapia y el desarrollo personal, para concluir que las técnicas y recursos empleados en teatro del oprimido, que proceden de fuentes muy diversas, siguen teniendo potencialidades indudables en propuestas de intervención social, cultural y educativa propias de la pedagogía teatral y la pedagogía social.Cómo referenciar este artículoVieites García, M.

    Full Text Available A presente investigação teve como objetivos: analisar animais presentes em diferentes criações de javalis no estado de São Paulo, com o intuito de auxiliar a identificação de javalis "puros" assim como javalis híbridos provenientes do cruzamento com o suíno doméstico, para tanto foram utilizadas avaliação do fenótipo dos animais, análises citogenéticas e da técnica molecular de RAPD (Random Amplified Polymorphic DNA.O estudo do número de cromossomos nas células diplóides em 104 animais destinados a análise citogenética e fenotípica, revelou polimorfismo de 2n=36, 37 e 38 cromossomos. Por meio da técnica de bandamento GTG foi possível identificação da translocação Robertsoniana entre os cromossomos 15 e 17 como responsável por esse polimorfismo. Todavia, somente com a análise citogenética isolada, não foi possível determinar se a origem desse polimorfismo é decorrente das hibridações com o suíno doméstico ou se são características inerentes ao javali. Contudo, quando associado a análise citogenética com as características fenotípicas, foi possível identificar a existência de hibridações. A análise citogenética nos animais submetidos a técnica de RAPD, revelou 2n=36 cromossomos nos 16 javalis assim como 2n=38 cromossomos nos 11 suínos e, por meio dessa técnica, foram possíveis agrupamentos, separando o suíno doméstico, javali e um possível híbrido revelando-se uma técnica com potencial no auxílio da identificação de híbridos.

    Intrauterine growth restriction (IUGR) may elicit a series of postnatal body developmental and metabolic diseases due to their impaired growth and development in the mammalian embryo/fetus during pregnancy. In the present study, we hypothesized that IUGR may lead to abnormally regulated DNA methylation in the intestine, causing intestinal dysfunctions. We applied reduced representation bisulfite sequencing (RRBS) technology to study the jejunum tissues from four newborn IUGR piglets and their normal body weight (NBW) littermates. The results revealed extensively regional DNA methylation changes between IUGR/NBW pairs from different gilts, affecting dozens of genes. Hiseq-based bisulfite sequencing PCR (Hiseq-BSP) was used for validations of 19 genes with epigenetic abnormality, confirming three genes (AIFM1, MTMR1, and TWIST2) in extra samples. Furthermore, integrated analysis of these 19 genes with proteome data indicated that there were three main genes (BCAP31, IRAK1, and AIFM1) interacting with important immunity- or metabolism-related proteins, which could explain the potential intestinal dysfunctions of IUGR piglets. We conclude that IUGR can lead to disparate DNA methylation in the intestine and these changes may affect several important biological processes such as cell apoptosis, cell differentiation, and immunity, which provides more clues linking IUGR and its long-term complications.

  16. The spatial ecology of free-ranging domestic pigs (Sus scrofa) in western Kenya.

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

    Vocalizations have long been recognized to encode information about an individual's emotional state and, as such, have contributed to the study of emotions in animals. However, the potential of vocalizations to also encode information about an individual's emotional reactivity has received much less attention. In this study, we aimed to test whether the vocalizations of domestic pigs contain correlates of emotional reactivity that are consistent between different contexts. We recorded vocalizations of 120 young female pigs in an experimental arena in two consecutive recording contexts, social isolation and an encounter with a familiar human. Simultaneously, we measured their heart rate and behaviour to determine their emotional reactivity in the same context (within-context). In addition, we aimed to determine the subjects' emotional reactivity in other contexts (across-context) by measuring their behaviour in four common tests of emotional reactivity, the human approach test, the open door test, the open field test and the novel object test. Using a cluster analysis, we identified four different call types. Significant inter-context correlations were found for all call types, suggesting that pig vocalizations are consistent within an individual across contexts. The call rate and the proportions of the individual call types were found to correlate significantly with indices of emotional reactivity both within and across contexts. Thereby, we found more significant correlations to indices of emotional reactivity within context (behavioural and physiological response during recording) compared to across context (behavioural response in the four emotional reactivity tests). The consistency of the vocal correlates to emotional reactivity between the different contexts depended on the call type. While we found moderate evidence that the high grunt is indicative of more active, more explorative and less fearful individuals both within as well as across contexts, the other call types provided less consistent results. Thus, it seems that some call types are better suited to provide information on a caller's emotional reactivity than others, and further research is needed to clarify the underlying influential factors.

    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.

    2017-01-01

    Full Text Available The article presents a comparative analysis of four methods for quantifying the protein-peptide complexes content in extracts obtained from animal raw materials, as well as the low- and highmolecular weight extract fractions: the direct spectrophotometric determination at wavelengths of 260 and 280 nm with subsequent calculation by the Kalckar formula; the biuret reaction by the Kingsley-Weichselbaum method; the method with Bradford reagent and the standard Lowry method. Experimental data analysis demonstrates that in case of the extract that contains protein-peptidic complexes in different molecular weights range, the Kingsley-Weichselbaum method shows the highest quality of protein concentration determination; while studying highmolecular weight fraction (more than 30 kDa, it is possible to obtain more information by combining the spectrophotometric method and the Kingsley-Weichselbaum method. Low-molecular weight fractions (less than 30 kD should be investigated by complex methods including the spectrophotometric method, Lowry and Bradford methods. These methods make it possible to presumably estimate protein molecules size ranges (by amount of peptide bonds, and also to determine hydrophobic and aromatic amino acids presence.

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

    Nicolas Mary

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

    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.

    preliminary study on insects associated with pig carcasses was conducted in Phitsanulok, northern Thailand. Five decomposition stages of pig carcasses were categorized: fresh (0-1 day after death), bloated (2 days after death), active (3 days after death), advanced (4- 6 days after death) and dry (7-30 days after death). The arthropod species collected from the corpses in the field sites were mainly classified belonging to two orders and nine families, namely order Diptera (family Calliphoridae: Chrysomya rufifacies and Chrysomya megacephala, family Muscidae: Musca domestica, family Faniidae: Fannia canicularis, family Sarcophagidae: Parasarcophaga ruficornis and family Piophilidae: Piophila casei,) and order Coleoptera (family Dermestidae: Dermestes maculatus, family Histeridae: Hister sp., family Cleridae: Necrobia rufipes and family Trogidae: Trox sp). The forensically dominant fly was C. rufifacies, while the beetle was D. maculatus. The beetles associated with pig carcasses found in this study are first reported in Phitsanulok, Thailand. In addition, ants, bees, spiders and millipedes were also associated with the carcasses. These findings may provide data for further use in legal investigations in Thailand.

    Brucellosis and tularemia are classical zoonotic diseases transmitted from an animal reservoir to humans. Both, wildlife and domestic animals, contribute to the spreading of these zoonoses. The surveillance of the animal health status is strictly regulated for domestic animals, whereas systematic disease monitoring in wildlife does not exist. The aim of the present study was to provide data on the prevalence of anti-Brucella, anti-Francisella and anti-Yersinia antibodies in wild boars from North-Eastern Germany to assess public health risks. A total of 763 sera of wild boars from Mecklenburg-Western Pomerania hunted in 1995/1996 were tested using a commercially available Brucella suis ELISA, an in-house lipopolysaccharide (LPS)-based Francisella ELISA, and commercially available Western blot kits for the detection of anti-Francisella and anti-Yersinia antibodies. The Yersinia enterocolitica O:9 LPS is able to induce serological cross-reactions indistinguishable from brucellosis due to a similar immunodominant epitope in the Brucella O-polysaccharide. The Yersinia Western blot assay was, therefore, based on five recombinant Yersinia outer proteins which have been proved to be specific for the serodiagnosis of yersiniosis. Anti-Brucella, anti-Francisella and anti-Yersinia antibodies were detected in 22.0%, 3.1%, and 62.6% of the wild boars, respectively. The high seroprevalence of tularemia and brucellosis in wild boars indicates that natural foci of these zoonoses are present in wildlife in Germany. However, the impact of transmission of zoonotic pathogens from wildlife to livestock is unknown. Only careful and systematic monitoring will help to prevent the (re)emergence of these zoonotic diseases in domestic animals and consequently human infection.

    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 We have determined the crystal structure of porcine quinolinate phosphoribosyltransferase (QAPRTase in complex with nicotinate mononucleotide (NAMN, which is the first crystal structure of a mammalian QAPRTase with its reaction product. The structure was determined from protein obtained from the porcine kidney. Because the full protein sequence of porcine QAPRTase was not available in either protein or nucleotide databases, cDNA was synthesized using reverse transcriptase-polymerase chain reaction to determine the porcine QAPRTase amino acid sequence. The crystal structure revealed that porcine QAPRTases have a hexameric structure that is similar to other eukaryotic QAPRTases, such as the human and yeast enzymes. However, the interaction between NAMN and porcine QAPRTase was different from the interaction found in prokaryotic enzymes, such as those of Helicobacter pylori and Mycobacterium tuberculosis. The crystal structure of porcine QAPRTase in complex with NAMN provides a structural framework for understanding the unique properties of the mammalian QAPRTase active site and designing new antibiotics that are selective for the QAPRTases of pathogenic bacteria, such as H. pylori and M. tuberculosis.

    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.

    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.

    Bovine tuberculosis (bTB) is a zoonosis caused mainly by Mycobacterium bovis that affects domestic and wild animals. In Brazil, there are no epidemiological studies on tuberculosis in wild animal populations and their possible role in the disease maintenance in cattle herds; thus, the aim of this study was to evaluate the occurrence of tuberculosis in wild boars in Rio Grande do Sul, southern Brazil. Tissue samples of animals hunted under government consent were submitted to histopathology and M. bovis polymerase chain reaction (PCR) as screening tests; the positive samples were subsequently submitted to bacterial isolation, the gold standard diagnosis. Eighty animals were evaluated, of which 27.9% and 31.3% showed histopathological changes and M. bovis genome presence, respectively. Moreover, 23.8% of the animals had at least one organ with isolates classified as Mycobacterium tuberculosis complex (MTC). Three hunting points were risk factors for positive results on screening tests. This study shows the occurrence of tuberculosis in a wild boars' population, and raise the possibility of these animals to play a role as disease reservoirs in southern Brazil. These results may help to improve the Brazilian tuberculosis control programme, as well as elucidate the circulation of mycobacteria in this country. © 2017 Blackwell Verlag GmbH.

    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.

    Full Text Available Existe entre la Botánica y la Antropología una ciencia intermedia a la que, desde hace medio siglo, se ha dado el nombre de Etnobotánica. Como ocurre con otras ciencias interfacultativas o interdisciplinales la Etnobotánica no se puede definir fácilmente y por esto ha habido muchas diferencias de opinión en cuanto a su alcance y sus objetos. En su más amplio sentido, la Etnobotánica es el estudio de las relaciones que existen entre el hombre y su ambiente vegetal, es decir las plantas que lo rodean. En un sentido más restringido, se ha considerado solamente como el estudio del uso de las plantas cultivadas y silvestres por los pueblos primitivos, usualmente los aborígenes.

    Full Text Available El "coro" es un tabaco silvestre de Argentina y Chile cuyas raíces son empleadas como fumatorio y mascatorio desde tiempos inmemoriales por grupos indígenas. Si bien existen noticias sobre su empleo desde la época colonial, en la actualidad no hay consenso sobre su identidad botánica a la par que sus modalidades de obtención, procesado y consumo han sido escasamente descriptas. Se efectuaron campañas etnobotánicas al sudoeste de la provincia del Chaco donde se colectaron ejemplares que responden a dicho nombre vernáculo en compañía de indígenas y se analizaron fuentes bibliográficas históricas disponibles. Se comprobó in situ que los mocovíes actualmente fuman sus raíces mezcladas con tabaco tanto en contextos ceremoniales como extra-ceremoniales. Como resultado del análisis bibliográfico se infiere que también lo emplearon en el pasado de manera homóloga indígenas vilelas, qom (tobas; wichi y abipones. Se descarta la correspondencia del "coro" con especies de Trichocline por la inexistencia de registros etnobotánicos al respecto.

    Full Text Available Our aim was to evaluate the risk of human toxoplasmosis via meat consumption from wild boars by estimating the seroprevalence of Toxoplasma gondii in animals hunted in central Italy. Using a modified agglutination test, 213 sera from wild boars were examined for anti-Toxoplasma IgG antibodies. Diaphragm samples (n=65 from seropositive and seronegative animals were tested by nested-PCR to detect T. gondii DNA. Toxoplasma DNA from diaphragms was genotyped by PCR-RFLP using 12 genetic markers. Moreover, the aim of the study was also to identify helminth infections of wild boars in the selected area and to evaluate their hazard for humans. Examination of sera revealed a seroprevalence of 12.2%. Only one T. gondii strain could be genotyped from a seropositive animal and PCR-RFLP revealed that it belonged to type II. Analysis of 50 samples of faeces and 32 small intestines revealed that 78% and 15.6% of the samples harboured parasites, respectively, with the occurrence of parasites potentially dangerous for humans. These latter included Ascaris suum, Macracanthorhynchus hirudinaceus, Trichuris suis, and Metastrongylus spp. A significant association was found between coprological positivity and male sex. These results indicate that T. gondii infection may be present in wild boar tissues and consumption of undercooked or raw wild boar meat may expose humans to risk of toxoplasmosis in the study area. Furthermore, the study highlights that wild boars are hosts of helminths of veterinary and medical importance transmissible to pigs and humans.

In addition, were calculated the half number of alleles by locus (MNA, the allelic frequencies, the expected (He and the observed (Ho heterozygosity , the content of polymorphic information (PIC, as well as the balance Hardy-Weinberg (EHW and the FIS for marker. The half number of alleles found by locus has been of 6.2 and the percentage of individual heterozygote behaved above of 60%. Of the entirety of the studied loci the 68% showed a high PIC. These results show that the Ecuadorian Creole pig possesses a high genetic diversity, essential information to optimize the national strategies of conservation and it improvement of this genotype in Ecuador.

    In the European Union, various fluoroquinolones are authorised for the treatment of food producing animals. Each administration poses an increased risk of development and spread of antimicrobial resistance. The aim of this study was to investigate the impact of parenteral administration of enrofloxacin on the prevalence of enrofloxacin and ciprofloxacin susceptibilities in the commensal intestinal E. coli population. E. coli isolates from faeces of twelve healthy pigs were included. Six pigs were administered enrofloxacin on day 1 to 3 and after two weeks for further three days. The other pigs formed the control group. MIC values were determined. Virulence and resistance genes were detected by PCR. Phylogenetic grouping was performed by PCR. Enrofloxacin and ciprofloxacin were analysed in sedimentation samples by HPLC. Susceptibility shifts in commensal E. coli isolates were determined in both groups. Non-wildtype E. coli could be cultivated from two animals of the experimental group for the first time one week after the first administration and from one animal of the control group on day 28. The environmental load with enrofloxacin in sedimentation samples showed the highest amount between days one and five. The repeated parenteral administration of enrofloxacin to pigs resulted in rapidly increased MIC values (day 28: MIC up to 4 mg/L, day 35: MIC ≥ 32mg/L). E. coli populations of the control group in the same stable without direct contact to the experimental group were affected. The parenteral administration of enrofloxacin to piglets considerably reduced the number of the susceptible intestinal E. coli population which was replaced by E. coli strains with increased MIC values against enrofloxacin. Subsequently also pigs of the control were affected suggesting a transferability of strains from the experimental group through the environment to the control group especially as we could isolate the same PFGE strains from both pig groups and the environment.

    The obtained results indicate that consumption of raw or undercooked meat from wild boars can carry an important risk of toxoplasma infection. Post mortem detection of antibodies in meat juice samples using ELISA is a useful alternative to blood serum examination. In addition, a diaphragm sample has been well-proven as a matrix sample for the contemporaneous diagnostics of trichinellosis and toxoplasmosis.

    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.

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

    Thomas Cucchi

    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.

    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.

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

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

    Full Text Available The identification of the genotypes of Echinococcus granulosus present in livestock and wild animals within regions endemic for cystic echinococcosis (CE is epidemiologically important. Individual strains display different biological characteristics that contribute to outbreaks of CE and that must be taken into account in the design of intervention programs. In this study, samples of hydatid cysts due to E. granulosus were collected from alpacas (4 in Puno and pigs (8 in Ayacucho in Peru, an endemic region for CE. Polymerase chain reaction amplification and DNA sequencing of specific regions of the mitochondrial cytochrome C oxidase subunit 1 and NADH dehydrogenase subunit 1 genes confirmed the presence of a strain common to sheep, the G1 genotype, in alpacas. Two different strains of E. granulosus were identified in pigs: the G1 and the G7 genotypes. This is the first report of the G1 genotype of E. granulosus in alpacas in endemic regions of CE in Peru.

    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.

    Full Text Available vThis study was aimed at analysing the most relevant environmental variables involved in vehicle–wild boar road collisions in a Mediterranean area, starting from a territorial information system implemented in a GIS environment. Landscape structure indices and local qualitative and quantitative variables were correlated to identify the most frequent predisposing factors of collisions. Statistical tests of the considered parameters indicated a higher frequency of collisions in the evening hours of late summer and autumn (P<0.05 compared with daytime and night-time, localized nearness to attraction points (feeding or resting sites; P<0.001 and closeness to no-hunting areas (P<0.001. In addition, local road parameters (shape of road, visibility at road sides, etc. considerably increased the risk of collisions.

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

    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

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

    Full Text Available Blood samples for determining of epinephrine concentration and biochemical parameters in the blood serum of wild boars were taken from 42 healthy wild boars, both sexes, during the hunting season. All animals in good condition, body weight 20 to 95 kg, were divided into two groups up to 50 kg (group A and up to 95 kg (Group B. Epinephrine concentration was determined by ELISA twice: one week after taking samples and a month after repeated freezing at -80°C. It was higher in relation to the reference value of domestic pigs and human (109.45 pg/ml in A and 119.54 pg/ml in B group. Repeated freezing and re-analysis after a month were resulted in lower concentrations of epinephrine (12% in young and 11.17% in adult animal, but without statistical significance (P>0.05. Biochemical analysis results’ show increased glucose and triglycerides concentrations compared to the reference values, while other indicators were observed within or slightly increased referring to the normal range. The correlation between glucose and epinephrine was not determined.

    The objective of this study was to identify the bioserotypes and virulence markers of Yersinia enterocolitica strains isolated from wild boars in Poland. Bacteriological examination of 302 rectal swabs from 151 wild boars resulted in the isolation of 40 Y. enterocolitica strains. The majority of the examined strains (n = 30), belonged to bioserotype 1A/NI. The presence of individual Y. enterocolitica strains belonging to bioserotypes 1B/NI (3), 1A/O:8 (2), 1A/O:27 (2), 2/NI (1), 2/O:9 (1) and 4/O:3 (1) was also demonstrated. Amplicons corresponding to ail and ystA genes were observed only in one Y. enterocolitica strain--bioserotype 4/O:3. The ail and ystB gene amplicons were noted in 11 Y. enterocolitica biotype 1A strains, although single amplicons of ystB gene were found in 28 of the tested samples. In four out of eight cases when two Y. enterocolitica strains were isolated from the same animal, the strains differed in biotype, serotype or virulence markers. The European population of wild boars continues to grow and spread to new areas, therefore, wild boars harbouring potentially pathogenic Y. enterocolitica 4/O:3 strains pose a challenge to public health.

    Full Text Available Esta pesquisa tem por objeto a análise da efetivação do direito fundamental ao meio ambiente sob a ótica da tutela à fauna silvestre, com base na Constituição Federal e em normas infraconstitucionais. Como se sabe, a Constituição de 1988 é um marco importantíssimo na evolução da defesa jurídica do meio ambiente, tendo desencadeado o surgimento de uma ampla legislação voltada à defesa de valores ambientais e, particularmente, da fauna silvestre. A partir da ótica constitucional e da legislação de proteção à fauna silvestre, como a Lei que cria Política Nacional do Meio Ambiente, a Lei que cria o Sistema Nacional de Unidades de Conservação – SNUC, a Lei de Uso Científico de Animais, a Lei de Rodeios e, em especial, a Lei de Proteção à Fauna, que foi recepcionada pela Constituição, é que se compõe o arsenal de ferramentas jurídicas que realizam a efetivação do direito fundamental ao meio ambiente animal. Por meio desse exame, identifica-se que a tutela da fauna silvestre acaba significando forma de efetivação do direito fundamental ao Meio Ambiente

    Full Text Available Uno de los rasgos más sobresalientes de la historia del folklore en España y otras naciones europeas son sus paradojas. Propuesto primero como ciencia ha llegado a ser claramente rechazado por posteriores ambientes científicos. Tendría interés hacer una historia social del folklore. Este artículo sugiere que tales paradojas y contradicciones están relacionadas con el paradigma científico que asumieron sus promotores, el evolucionismo cultural y con un concepto idealizado de "pueblo", que ayudaron a construir presentando colecciones de materiales. También analiza las diferentes funciones sociales que ha cumplido el discurso folklórico.

    Full Text Available OBJETIVO Descrever a investigação do surto de febre amarela silvestre e as principais medidas de controle realizadas no estado de São Paulo. MÉTODOS Estudo descritivo do surto de febre amarela silvestre na região sudoeste do estado, entre fevereiro e abril de 2009. Foram avaliados casos suspeitos e confirmados em humanos e primatas não humanos. A investigação entomológica, em ambiente silvestre, envolveu captura em solo e copa de árvore para identificação das espécies e detecção de infecção natural. Foram realizadas ações de controle de Aedes aegypti em áreas urbanas. A vacinação foi direcionada para residentes dos municípios com confirmação de circulação viral e nos municípios contíguos, conforme recomendação nacional. RESULTADOS Foram confirmados 28 casos humanos (letalidade 39,3% em áreas rurais de Sarutaiá, Piraju, Tejupá, Avaré e Buri. Foram notificadas 56 mortes de primatas não humanos, 91,4% do gênero Alouatta sp . A epizootia foi confirmada laboratorialmente em dois primatas não humanos, sendo um em Buri e outro em Itapetininga. Foram coletados 1.782 mosquitos, entre eles Haemagogus leucocelaenus , Hg. janthinomys/capricornii , Sabethes chloropterus , Sa. purpureus e Sa. undosus . O vírus da febre amarela foi isolado de um lote de Hg. leucocelaenus procedente de Buri. A vacinação foi realizada em 49 municípios, com 1.018.705 doses aplicadas e o registro de nove eventos adversos graves pós-vacinação. CONCLUSÕES Os casos humanos ocorreram entre fevereiro e abril de 2009 em áreas sem registro de circulação do vírus da febre amarela há mais de 60 anos. A região encontrava-se fora da área com recomendação de vacinação, com alto percentual da população suscetível. A adoção oportuna de medidas de controle permitiu a interrupção da transmissão humana em um mês, assim como a confirmação da circulação viral em humanos, primatas não humanos e mosquitos.

La actual transformación agrícola y urbana en Costa Rica ha generado preguntas acerca de la efectividad de la conservación y restauración dentro de las áreas protegidas. En este documento nosotros analizamos los patrones de cambio del uso del suelo entre tres periodos: 1997, 2005 y 2010 en términos de magnitud, dirección y velocidad a través de mapas categóricos generados por la foto-interpretación para dos áreas silvestres protegidas y sus áreas aledañas: Parque Nacional La Cangreja (LCNP, el Refugio de Vida Silvestre Rancho Mastatal (RMWR y sus áreas aledañas (SA, esta última compuesta por área de un kilómetro de radio fuera de los límites de las áreas protegidas. La matriz que describe el paisaje dentro de las áreas protegidas es la cobertura natural, compuesta principalmente por la cobertura forestal y tacotales. Encontramos que la cobertura natural más abundante para ambas áreas protegidas fue cubierta forestal en todos los años estudiados. La estabilidad y las grandes áreas de la cubierta forestal en LCNP y RMWR para 2005 y 2010 reflejan que las políticas, las acciones de manejo y vigilancia tienen un impacto positivo en la conservación y restauración de los hábitats naturales en esta zona del Pacifico Central Costarricense. Sin embargo, la alta complejidad del paisaje de SA en 1997, 2005 y 2010 son una prueba de presión antropogénica sobre estas áreas protegidas y sugieren una ineficacia de los gobiernos locales para monitorear y disminuir los cambios de uso del suelo que podrían obstaculizar la gestión, conservación y restauración de especies dentro de las áreas protegidas.

    Two Gram-stain-variable, non-motile, catalase-positive and cytochrome c oxidase-negative bacteria, designated AK20-18 T and AM20-54, were isolated from forest soil samples collected in the Italian Alps. Growth occurred at a temperature range of 5-30 °C, at pH 6-9 and in the presence of 0-5 % (w/v) NaCl. The 16S rRNA gene sequence similarity between strains AK20-18 T and AM20-54 was 100 %. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain AK20-18 T had highest 16S rRNA gene sequence similarity with the type strain of Arthrobacter psychrochitiniphilus (96.9 %). The cell-wall peptidoglycan structure of strain AK20-18 T was of the type A3alpha l-Lys-l-Thr-l-Ala2 (A11.27). The whole-cell sugars were galactose, ribose and lesser amounts of mannose. The major respiratory quinone of the two strains was menaquinone 9(H2) [MK-9(H2)], whereas MK-10(H2) was a minor component. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and unknown glycolipids. The major cellular fatty acids were anteiso-C15 : 0, iso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0. The genomic DNA G+C content was 59.9 mol%. Combined data of phylogenetic, phenotypic and chemotaxonomic analyses demonstrated that strains AK20-18 T and AM20-54 represent a novel genus and species, for which the name Psychromicrobium silvestre gen. nov., sp. nov. is proposed. The type strain of Psychromicrobium silvestregen. nov., sp. nov. is AK20-18 T (=DSM 102047 T =LMG 29369 T ).

  1. Humans (Homo sapiens) judge the emotional content of piglet (Sus scrofa domestica) calls based on simple acoustic parameters, not personality, empathy, nor attitude toward animals.

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

    2007-06-01

    This study aimed to investigate whether feed restriction and re-alimentation differently affect lipid content and activities of lipogenic or catabolic enzymes according to muscle types in pigs. At around 28 kg body mass (BW), sixty pigs (n=30 per group) were allocated to either ad libitum (AL) or restricted/re-feeding (RA) regimens. After feed restriction (80 kg BW), lipid content was reduced (P<0.01) in the oxidative rhomboideus (RH) as in the glycolytic biceps femoris (BF) muscles of RA pigs compared with AL pigs. Lower activities (P<0.05) of the lipogenic enzymes fatty acid synthase (FAS) and malic enzyme (ME) were observed in the RH but not in the BF of RA vs. AL pigs. After re-feeding (110 kg BW), lipid content was restored in the RH, but was still 12% lower (P<0.05) in the BF of RA compared with AL pigs. In the RH, the trend for an enhanced FAS activity and for a smaller weight-related decrease of ME activity in RA pigs than AL pigs during re-feeding, may have contributed to the muscle fat recovery observed in the RA pigs. In the BF, higher oxidative enzyme activities (P<0.10) in RA pigs compared to AL pigs might explain the incomplete lipid recovery observed after re-feeding in the former animals. In conclusion, metabolic activities in response to restriction and re-feeding differed according to muscle metabolic type.

    The DNA template used in the pig genome sequencing project was provided by a Duroc pig named TJ Tabasco. In an effort to annotate microRNA (miRNA) genes in the reference genome we have conducted deep sequencing to determine the miRNA transcriptomes in ten different tissues isolated from Pinky......, a genetically identical clone of TJ Tabasco. The purpose was to generate miRNA sequences that are highly homologous to the reference genome sequence, which along with computational prediction will improve confidence in the genomic annotation of miRNA genes. Based on homology searches of the sequence data...... against miRBase, we identified more than 600 conserved known miRNA/miRNA*, which is a significant increase relative to the 211 porcine miRNA/miRNA* deposited in the current version of miRBase. Furthermore, the genome-wide transcript profiles provided important information on the relative abundance...

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

    The Göttingen minipig is an excellent model for studying effects of dietary high-fat intake on obesity. In this study, we analyzed the expression level of microRNA-122 (miRNA-122) and its target mRNA, CAT1, in intact young male minipigs fed either high-cholesterol or standard diet for 11 wk. Mi...... with a decrease in the expression of miRNA-122, confirming the implication of this microRNA in obesity. Gene expression levels of CAT1 did not differ between groups.......RNA-122 and CAT1 are known to be important regulators of lipid metabolism. The weight of the young minipigs was monitored once a week during the feeding period; measurements of total cholesterol, triglycerides, high-density lipoproteins, and low-density lipoproteins were recorded at 4 time points (8, 14...

    Full Text Available The objective of this study was to examine iodine and selenium contents in skeletal muscles of selected species of game animals living in regions with low iodine and selenium contents in the soil and water. Iodine content was determined in 66 samples of skeletal muscles of red deer cut out of the musculus gracilis, 32 samples and 27 samples from the same muscle of roe deer and wild boar, respectively. The shot game animals came from hunting grounds in western and southern regions of the Czech Republic and in Protected Landscape Area Šumava. In red deer muscles the average iodine content was 44.9 ± 15.2 μg I·kg-1 wet weight with the range of 6.9 to 82.0 μg I·kg-1. The lower concentration in roe deer meat with the average 39.3 ± 14.1 μg I·kg-1 and the range from 18.3 to 84.4 μg I·kg-1 may be due to differences between biotopes and food. The average iodine concentration in the musculus gracilis of wild boars was 55.9± 27.0 μg·kg-1 wet weight. Selenium content was determined in 22 samples of red deer, 51 samples of roe deer and 27 samples of wild boar skeletal muscles. The average values of selenium content in the meat of red deer, roe deer and wild boars were 16.2 ± 8.4, 36.9 ± 16.6 and 27.6 ± 19.8 μg Se·kg-1 wet weight, respectively. All three species of game animals are characterised by low content and high variability of selenium concentration in meat with the minimum value 3.9 µg and maximum value 83.3 μg·kg-1 wet weight. The study brings new data on iodine and selenium content in the muscle of game animals in the Czech Republic.

    Full Text Available The aim of the present study was to determine heavy metal reference levels for exposure and risk assessment studies on a local scale. The average levels of cadmium recorded in 75 wild boars were 0.085, 0.079 and 1.052 mg Cd kg-1 wet weight (w.w. in the liver, muscle and kidney, respectively. The majority of the muscle samples and some of the liver samples contained levels of heavy metal that were over the legal limit [EU Maximum Residue Levels (MRLs] for pigs. Our data are similar to or lower than the values reported in most of the available literature. For Pb concentration, the average values recorded were 0.318, 0.126 and 0.298 mg kg kg-1 ww.w. in the liver, muscle and kidney, respectively. The samples that were non-compliant with regulatory limits (MRLs for pigs were registered only for muscle. Available data on the presence of Pb content in game meat report lower values than ours, most likely because the area around the bullet path was avoided while sampling. The average values of total Cr were 0.141, 0.139 and 0.097 mg Cr kg-1 w.w. in the liver, muscle and kidney, respectively. For Zn, the mean values were 49.76, 53.21 and 32.46 mg kg-1 w.w. in liver, muscle and kidney, respectively. Cu content was 46.12, 12.20 and 5.64 mg kg-1 w.w. in the liver, muscle and kidney, respectively. The results obtained have been validated on the basis of the scarce and inconsistent Italian literature available and on international studies.

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

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

    Full Text Available La memoria espacial se considera un factor selectivo en la evolución de la inteligencia. Los estudios en animales permiten pensar que los procesos cognitivos descriptos en humanos comparten características con los de otras especies. Se estudió el comportamiento espacial vinculado a la búsqueda del alimento de los monos capuchinos y su capacidad de retener información sobre la ubicación y estado del mismo. Durante los seguimientos de tres grupos de Cebus nigritus silvestres se aplicó un diseño observacional cualitativo que evaluó las cantidades de fruta madura e inmadura presentes en los árboles frutales consumidos por los monos en sus desplazamientos diarios. Las visitas a los árboles de frutos indicaron que los monos retienen información particular sobre la ubicación y condición de cada árbol. Los resultados obtenidos son fundamentales para la comprensión del funcionamiento de los mecanismos cognitivos no mediados por el lenguaje, lo cual permite ampliar los conocimientos de la base biológica del comportamiento espacial no humano. Palabras clave: Cebus=Sapajus nigritus; árboles frutales; velocidad de acercamiento; visita Spatial memory is considered a selective factor in the evolution of intelligence. Animal studies lead us to believe that cognitive processes described in humans may have much in common with those of other species. We studied the foraging spatial behavior of capuchin monkeys and their ability to retain information about food location and quality. We analyzed whether individuals were able to integrate stored information about food sites and changes in the ripening of the resource. A qualitative observational design was used to monitor three groups of wild Cebus nigritus in their daily movements, evaluating the amounts of ripe and unripe fruit present in the fruiting trees consumed by monkeys. Visits to fruiting trees showed that monkeys remember specific information on the location and condition of each tree

A diferencia de las células madre ovogoniales (hembras, numerosas CME pueden ser obtenidas durante el periodo postnatal prepuberal pre-meiosico. Estas células pueden ser aisladas, amplificadas in vitro y criopreservadas, para así crear líneas celulares. Las CME pueden inducirse a diferenciar in vivo e in vitro. Las metodologías in vivo, están basadas en el transplante de CMEs del testículo de un animal donador al testículo de otro receptor sin espermatogenesis, técnicas ya establecidas en animales de laboratorio con potencial para utilizarse en animales domésticos y silvestres. Estos últimos, podrían donar CMEs y animales de especies filogenéticamente relacionadas no amenazadas serían receptores para producir espermatozoides de la especie amenazada. Existen técnicas de transplante de material testicular preservado de diversos animales al tejido subcutáneo de ratones, donde se desarrolla la espermatogénesis completa. La espermatogénesis in vitro está disponible en ratones. Independientemente de la metodología utilizada, los espermatozoides obtenidos de CME pueden utilizarse en técnicas de reproducción asistida para generar embriones y/o nuevos individuos a fin de repoblar ecosistemas en desequilibrio o aumentar las tasas de mejoramiento genético en sistemas de producción animal.

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

En el caso específico del silicio, las plantas que lo acumulan pueden formar fitolitos, muy útiles en paleoecología y arqueología. Se recolectaron especies de plantas de varias partes del centro-occidente de México y se determinó su composición elemental mediante sonda dispersiva de rayos X acoplada a un microscopio electrónico de barrido. Las plantas semiparásitas (plantas que fotosintetizan pero que toman sus nutrientes de la planta que parasitan acumulan cantidades considerables de iones como potasio y cloro para usarlos como osmolitos. Tillandsia recurvata, a pesar de ser epífita, acumula una buena cantidad de silicio, lo mismo que Cyperus sp., registrada como acumuladora de este elemento. Otras especies como Tagetes micrantha, de uso en la cocina mexicana, podrían contribuir en alguna medida al aporte de micronutrientes como potasio y magnesio.

  11. Are camouflaged seeds less attacked by wild birds? Sementes camufladas são menos atacadas por aves silvestres?

    2010-04-01

    Full Text Available Wheat, corn and rice crops in Brazil use seeds treated with systemic insecticide/nematicide carbofuran, mixed to rhodamine B red dye. Carbofuran is toxic and rhodamine B is attractive to wild birds that eat up these seeds, resulting in notable mortality during planting. A field experiment was performed in southeast Brazil to evaluate if camouflaged seeds would be less consumed by wild birds in comparison to commercial seeds with red-colored rhodamine B and aposematic blue seeds. Camouflaged seeds were less removed than seeds with rhodamine B and natural colors. The camouflaging was more effective in the presence of irregularities and litter. There was no removal of blue-colored seeds. As legislation requires treated seeds to receive a different color to avoid accidents with humans, camouflaging may be used as replacement of rhodamine B to reduce mortality rates of wild birds.Plantações de trigo milho e arroz no Brasil utilizam sementes tratadas com o inseticida e nematicida sistêmico carbofuran, associado ao corante vermelho rodamina B. O carbofuran é tóxico e a rodamina B é atrativa às aves silvestres, as quais consomem estas sementes, resultando em notável mortalidade durante o plantio. Um experimento realizado em campo agrícola no sudeste do Brasil mostrou que sementes camufladas foram menos removidas por aves silvestres do que sementes com rodamina B. A camuflagem foi potencializada em presença de irregularidades e serrapilheira no solo. Não houve remoção de sementes de cor azul, mas a formulação granular de cor azul tem causado mortalidade de aves nos USA e Canadá. Como sementes tratadas com agrotóxicos devem, de acordo com a legislação, receber coloração diferenciada para evitar acidentes com humanos, a camuflagem pode ser utilizada, substituindo a rodamina B.

Como parte de la exploración de su potencial agroindustrial se identificó y cuantificó a los ácidos grasos del aceite de semilla de vid silvestre (Vitis spp. de frutos de Temascaltepec, México y de la accesión E-201, cultivada en Zumpahuacán, México. El contenido promedio de aceite en la semilla fue de 16,7%, encontrando ácido linoleico (71,5%, oleico (17,2%, palmítico (6,6% y esteárico (4,3%. En el aceite obtenido en vides de Temascaltepec se determinó índice de yodo (57,9 g/100 g, índice de saponificación (170,7 mg/g e índice de peroxidos (30 mEq/kg, valores relacionados posiblemente al contenido de ácidos grasos insaturados. Sin embargo, ese mismo grado de insaturación no concordó con el punto de humeo observado (211 °C, lo cual posiblemente está relacionado con el contenido de ácidos palmítico y esteárico. El aceite de semilla de vid silvestre cumple parcialmente con los estándares establecidos para el aceite de semilla de V. vinifera, lo cual implica su potencial culinario, agroindustrial y cosmetológico.

    Full Text Available Se presenta un estudio sobre la fauna silvestre de la Sierra del Ajusco y la Sierra Nevada, localizadas dentro de la Faja Volcánica Transmexicana (FVT, en la porción oriental del límite meridional de la Cuenca de México. La enorme riqueza biológica de esta zona que rodea la zona metropolitana de la ciudad de México, uno de los mayores complejos urbanos del mundo, ha sobrevivido durante décadas al impacto de la urbanización de las áreas forestales, explotación de recursos naturales, contaminación, cacería, incendios y pastoreo. A pesar de esto, se desconocen muchos de los factores que regulan la dinámica de los ecosistemas en esta región. Con relación a la fauna silvestre la carencia de información es mucho más evidente, aspectos elementales como la diversidad de especies, las interacciones ecológicas, la función de los organismos en el ecosistema, las condiciones de estrés a que están sometidos, han sido poco explorados. En esta investigación se recurrió a observaciones de campo y a la consulta de diferentes fuentes bibliográficas para estimar la riqueza de especies de mamíferos, aves, reptiles y anfibios; las relaciones ecológicas entre los mismos y las consecuencias de la modificación de su hábitat producto de las actividades humanas.

Se realizaron recorridos nocturnos entre las 8:00 p. m. y 4:00 a. m., la playa se dividió en cinco sectores, en estos se realizaron observaciones directas y de rastros, de las tortugas que elaboraron el nido, entre febrero y agosto del 2011 y 2012. Se registraron tres especies de tortugas marinas, Dermochelys coriacea, Eretmochelys imbricata y Chelonia mydas. La anidación de tortugas baula tuvo su punto máximo entre marzo y julio; por su parte, las carey, entre mayo y junio (2011, y junio hasta agosto en el 2012. Se observó preferencia en la posición de la playa utilizada para construir sus nidos; la baula utiliza principalmente la parte media, mientras que la carey utilizó mayormente la parte baja para anidar (t = 17.2525. Se observó que la baula utilizó frecuentemente el sector C; sin embargo, no se encontraron diferencias en el uso de los sectores. Se concluye que ambas especies tienen preferencias en la selección de la zona de playa en que anidan; la carey en la parte baja cerca de la línea de costa y la baula en la parte media. Además, las tortugas baula utilizan indistintamente los diferentes sectores de la playa estudiada.

    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.

    Mycobacterium africanum, siendo el primer reporte de estas micobacterias para primates del Nuevo Mundo. La prevalencia para MNT fue de 7,2% perteneciendo a las especies Mycobacterium phlei, M. terrae, M. vaccae, M. flavescens, M. flavescens y M. zsulgaii, algunas de estas, patógenos oportunistas. No existe una diferencia a nivel descriptivo en cuanto a la edad, al sexo y al tipo de entrega de los individuos infectados con MNT y micobacterias tuberculosas con respecto a los individuos que no las presentaron. Los primates del Nuevo Mundo pueden ser portadores sanos de micobacterias tuberculosas lo que representa un riesgo para la salud humana, y con ciertas especies de micobacterias, podría ser un riesgo para las poblaciones de primates silvestres en caso de que estos primates sean liberados en el medio silvestre. Este estudio es relevante para el país, ya que integra conceptos médicos tanto epidemiológicos como microbiológicos, con aspectos relacionados con la conservación de la fauna silvestre.

    Full Text Available Los diferentes estudios etnobotánicos y etnoecológicos, muestran no solo la gran riqueza de recursos naturales que muchas comunidades han aprovechado de manera sostenible en el tiempo, si no también, la preocupación por la falta de sistematización del conocimiento debido a diferentes situaciones que lo dificultan. Esta investigación tiene como propósito mostrar los diferentes sistemas de transmisión del conocimiento que los habitantes del municipio de Turbo, Antioquia, Colombia, han utilizado para que las generaciones presentes y futuras reconozcan las plantas silvestres comestibles, lo cual es útil para tomar decisiones frente a la necesidad de sistematización del conocimiento de la biodiversidad local. Se utiliza una metodología que comprende las etapas de diseño de la encuesta etnobotánica, la aplicación de la misma teniendo en cuenta el tamaño de la población lo que arroja un total de 360 encuestas aplicadas en los 18 corregimientos del municipio, agrupados en cuatro sectores fisiográficos: Serranía, Litoral, Abanico Aluvial y Planicie Inundable. Los resultados muestran las formas de transmisión de conocimiento en cada uno de los corregimientos que componen la geografía del territorio, evidenciando que continúan primando sistemas de transmisión oral con muy baja sistematización y con un desinterés de la población joven por reconocer dichos recursos orientados a la preservación como fuentede alimento.

    Full Text Available A biossegurança em áreas de confinamento de animais silvestres é questão fundamental para a saúde pública, sobretudo em locais onde os animais são considerados protagonistas da atração, como em parques zoológicos. Estes locais, apesar de toda segurança envolvida na contenção e manejo dos animais, ainda podem ser considerados como ponto de transmissão de zoonoses. Objetivou-se avaliar o grau de insalubridade dos funcionários e o uso de equipamentos de proteção contra patógenos de caráter zoonótico em áreas de confinamento de animais silvestres. O estudo foi realizado através da análise dos dados obtidos por meio de questionário aplicado aos trabalhadores de áreas de confinamento de animais silvestres, cujo enfoque era sobre a rotina de trabalho, manejo dos animais, histórico de saúde e o conhecimento acerca de doenças zoonóticas. As informações coletadas revelaram que, em parte, a administração do local proporciona aos funcionários uma segurança básica, fornecendo EPIs e cursos de atualização no manejo dos animais. Entretanto, a vestimenta utilizada pelos funcionários é lavada em suas próprias residências. Ainda há pontos a serem corrigidos na biossegurança nestes parques, como a construção de vestiários e uniformes próprios, com a lavagem do mesmo em um setor de lavanderia no próprio local.

  15. Behavioral experiments in a wild passerine cause short-term reductions in parental provisioning and nestling mass Experimentos conductuales en un ave paserina silvestre causan reducciones de corto plazo en el cuidado parental y peso de pichones

    Full Text Available Research on wild animals often involves the capture and temporary removal of individuals from their territory. Although the acute effects of such procedures are well understood in terms of stress hormone profiles, their effect on the behaviour of captured individuals after release is poorly known. Additionally, for socially-monogamous individuals captured whilst breeding, little is known regarding whether the remaining individual compensates for the temporary loss of its partner and whether offspring condition or survival ultimately decreases due to any reductions in parental provisioning. We investigated the influence of field-based experiments requiring temporary adult removal on adult provisioning behaviour and nestling mass in the thorn-tailed rayadito (Aphrastura spinicauda, a Chilean furnariid species with equal parental effort between sexes. During the absence of the removed individual, remaining individuals did not increase nestling provisioning rates while, upon their release, removed individuals did not return to nestling feeding for at least 38 minutes and typically much longer. This drastic reduction in combined parental provisioning negatively affected nestling mass, while average nestling mass increased during a control period, nestlings failed to gain weight during and subsequent to parental removal. Finally, our experiments did not affect fledging probability. Overall, our results indicate that the temporary removal of rayaditos from their territories can cause short-term reductions in parental provisioning and nestling weight, but is unlikely to lead to any long-term effects on nestling survival.Las investigaciones en animales silvestres frecuentemente requieren la captura y remoción de individuos de sus territorios. Si bien se conocen los efectos a nivel hormonal de tales métodos, sus efectos sobre la conducta de los individuos después de la liberación son escasamente conocidos.

    Full Text Available Se hace una revisión sobre el origen de la concepción de vida silvestre, rastreando su significado desde el siglo XIV hasta el presente. Aunque existen en Inglaterra referencias muy antiguas sobre la concepción de vida silvestre, es en Estados Unidos donde nace y evoluciona dicho término. Al comparar las concepciones de la vida silvestre en los Estados Unidos respecto a los países latinoamericanos, se evidencia la enorme importancia cultural, educativa, política y social dada a tales concepciones en el continente norteamericano en contraste con Latinoamérica, particularmente Colombia, en donde no se dan tales manifestaciones. Igualmente, la historia de la educación e investigación en educación sobre la vida silvestre en los Estados Unidos revela una notoria inserción de esta temática tanto en los textos divulgativos (educación no formal como en la literatura científica y en los currículos de educación básica y universitaria. En dicho país es posible conjeturar un cambio evolutivo en la concepción de vida silvestre que, de acuerdo con nuestra investigación, se inicia a finales del siglo XIX con un significado de fauna de caza deportiva y culmina, hacia la década de 1970 con la inclusión de todos los reinos de la naturaleza así como su hábitat e interrelaciones. En nuestro país, y en general para Suramérica, es muy escasa la literatura especializada sobre vida silvestre, no existiendo facultades o carreras con dicha temática a pesar de la enorme biodiversidad de este continente. Algunas de las razones aducidas por el autor, que explican esta situación, son la influencia de la visión taxonómica de la naturaleza, privilegiada en Colombia por la Expedición Botánica, y la dificultad para incorporar la educación ambiental en el contexto académico universitario. Se concluye igualmente la escasa investigación en vida silvestre y el potencial que existe para desarrollarla en el campo de las ciencias naturales y sociales

    Full Text Available The objective of this study was to investigate the frequency of occurrence and variety of intestinal parasites among free-living wild animals. Fecal samples from wild mammals and birds at rehabilitation centers in the states of Mato Grosso do Sul and São Paulo were analyzed by sedimentation and flotation-centrifugation methods. Parasite eggs, oocysts, cysts and/or trophozoites were found in 71% of the samples. Cryptosporidium sp. oocysts were detected in fecal samples from oncillas (Leopardus tigrinus and scaly-headed parrots (Pionus maximiliani. Giardia cysts were identified in the feces of a gray brocket (Mazama gouazoubira. Among the most common parasites found, there were eggs from Toxocara cati, Toxascaris leonina and Ancylostoma tubaeforme, and from Cestoda. Several Enterobius sp. eggs were found in the feces of red howler monkeys (Alouatta seniculus. It can be concluded from this study that despite the small number of samples, the diversity of parasites found was noteworthy. Additional information about parasite endofauna in wild animals is needed, since their presence might suggest that there could be proximity to and interactions with domestic animals and/or humans. In addition, further studies on parasites from free-living wild animals are of prime importance for understanding the intensity of anthropic changes in wild environments.O objetivo deste trabalho foi pesquisar a frequência de ocorrência e a variedade de parasitas intestinais de animais silvestres de vida livre.

    Mark Rademaker

    Full Text Available 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.

    Full Text Available Twenty-eight isolates of Histoplasma capsulation were obtained from eight species of forest mammals from the States of Amazonas, Pará and Rondônia in the Amazon Region of Brazil. Primary isolates were obtained by inoculating triturated liver and spleen tissue intradermally and intraperito-neally in hamsters. Mycological diagnosis in hamsters presenting lesions was confirmed by histopathology and culture on Sabouraud dextrose-agar. Infected hamsters developed signs of disease within two to nine months; all had disseminated visceral lesions and most also had skin lesions at the sites of inoculation. None of the hamsters inoculated with skin macerates of the original hosts developed histoplasmosis, and histopathological examination of the viscera of the wild hosts failed to reveal H. capsulation. Prevalence of infection was considerably higher in females than in males both for the opossum Didelphis marsupialis and for total wild animals (479 examined. It is proposed that canopy-dwelling mammals may acquire the infection from conidia borne on convective currents in hollow trees with openings at ground-level.Vinte e oito amostras de Histoplasma capsulatum foram obtidas de oito espécies de mamíferos silvestres nos Estados do Amazonas, Pará e Rondônia. Os isolamentos foram feitos mediante inoculação de amostras trituradas de fígado e baço em hamsters por via intradérmica e intraperitoneal. O diagnóstico micológico nos hamsters que apresentaram lesões foi confirmado por histopatologia e cultivo em meio dextrose-agar de Sabouraud. Os hamsters infectados desenvolveram sinais de doença após dois a nove meses; todos apresentaram lesões disseminadas nas vísceras e a maioria apresentou também lesões cutâneas nos locais da inoculação. Nenhum dos hamsters inoculados com material de pele dos hospedeiros originais desenvolveu histoplasmose, e H. capsulatum não foi detectado nos exames histopatológicos dos animais silvestres.

    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.

    Full Text Available En los Andes colombianos, un gran número de artesanías se fabrican a partir de raíces adventicias de plantas nativas que crecen de forma silvestre. Sin embargo, la deforestación y las prácticas no sustentables han diezmado la disponibilidad de plantas silvestres productoras de fibra. En este estudio evaluamos la disponibilidad de fibras de tres especies en Santa Elena (Antioquia, Colombia: Asplundia sarmentosa, Philodendron aff. sagittifolium y Clusia multiflora. Después de una búsqueda exhaustiva en la zona de estudio ubicamos menos de 30 individuos adultos de cada especie. Para cada planta se midieron las variables asociadas al tamaño de la planta y se registró el número y la longitud de raíces maduras e inmaduras. Se pesaron fragmentos de raíces para estimar la biomasa. El crecimiento de raíces de cada planta fue monitoreado mensualmente durante siete meses. La disponibilidad actual de fibra (raíces maduras es de ca. 3 352 m (Asplundia 1 481 m, Clusia de 952 m, Philodendron 918 m, con esta cantidad de material se pueden elaborar entre 419 a 838 canastos. De acuerdo a la tasa de crecimiento mensual, una nueva raíz podría alcanzar un tamaño para ser cosechado entre el mes 38 y 71. Plantas más grandes tienen mayor cantidad de raíces maduras, sin embargo, la tasa de crecimiento no está asociada al tamaño de la planta. Nuestros resultados proveen evidencia de que las plantas en Santa Elena presentan una relación (tamaño de la planta, número de raíces maduras que es similar a plantas que se encuentran en zonas no intervenidas, no obstante, la cosecha de fibras en Santa Elena no es una actividad sostenible debido al bajo número de individuos susceptibles de ser cosechados, la lenta tasa de crecimiento de raíces y la alta demanda de fibras.

    Full Text Available Este artigo descreve a trajetória do projeto EnsinaSUS, da pesquisa desenvolvida em seu interior e das múltiplas dimensões e implicações na direção do conhecimento das experiências que têm sido realizadas nos cursos da área de saúde em relação aos processos de mudança que estão em desenvolvimento. Pretendemos compartilhar a experiência de integração de pesquisadores, de diferentes origens institucionais e profissionais, na construção de um projeto comum, alimentado da vivência desses atores. Essa experiência almejou inovar e construir uma nova gramática para discussão e compreensão dos processos pedagógicos e sua interface com a saúde e o trabalho, na produção de um cuidado que se faça distinto na concepção da assistência à saúde, produzindo cuidado usuário-centrado, numa perspectiva dialógica e ético-política. Entendemos que as práticas de ensino e extensão funcionam como dispositivos abertos de um 'fazer-pensar-saber' em integralidade, forjando novas concepções, sentidos e significados da saúde, da vida, do conhecimento e da educação. Pautamo-nos na idéia de que as explicações da práxis pedagógica podem ser entendidas como possibilidade da construção histórica da cidadania. Encontramos alguns mecanismos de legitimação e canais de articulação, intercâmbio e solidariedade como resposta de interação de diversidades. A equipe representou a composição de redes de representação em espaços culturais e políticos plurais.This article describes the EnsinaSUS Project, the research developed within the project, and the various dimensions and implications that will lead to understanding the experiences that have been taking place in courses in the field of health care as regards their processes of change.

    2018-03-01

    We present a major update to ElecSus, a computer program and underlying model to calculate the electric susceptibility of an alkali-metal atomic vapour. Knowledge of the electric susceptibility of a medium is essential to predict its absorptive and dispersive properties. In this version we implement several changes which significantly extend the range of applications of ElecSus, the most important of which is support for non-axial magnetic fields (i.e. fields which are not aligned with the light propagation axis). Supporting this change requires a much more general approach to light propagation in the system, which we have now implemented. We exemplify many of these new applications by comparing ElecSus to experimental data. In addition, we have developed a graphical user interface front-end which makes the program much more accessible, and have improved on several other minor areas of the program structure.

    The international SusHouse project has developed a strategy design approach that can contribute to major (factor 20) efficiency improvements in household activities. Stakeholder workshops have been held to develop scenarios for a sustainable future (2050). These scenarios were evaluated on their economic consequences, environmental impacts and consumer acceptance. the results were then used as the input for a second round of stakeholder workshops, which aimed at developing short-term strategies and implementation plans. This Research Note reviews the SusHouse approach and its results. It ends with suggestions for further steps to be taken. A SusHouse CD-ROM is available, containing all final project reports as well as a scenario presentation in the form of images and short texts. 22 refs

    Full Text Available Con la finalidad de obtener híbridos somáticos interespecíficos, se fusionaron protoplastos de la especie tetraploide Solanum tuberosum y de la especie silvestre diploide Solanum circaeifolium utilizando polietilenglicol. Los productos de fusión fueron cultivados en el medio V-KM suplementado con albúmina de suero bovino. Las primeras divisiones celulares ocurrieron a los 3 a 4 días de cultivo. Después de la formación de colonias se observó una rápida proliferación de callos, a partir de los cuales se regeneraron 19 plantas. El análisis molecular usando RAPD, confirmó que los regenerantes presentaban segmentos de ADN de ambos parentales, sugiriendo su posible naturaleza de híbridos somáticos. Las observaciones del número de cromosomas indicaron que todos los híbridos fueron aneuploides. En condiciones de invernadero, los regenerantes derivados de la fusión de protoplastos, mostraron características morfológicas intermedias entre las líneas parentales. Este estudio muestra la producción de híbridos somáticos de papa con el método de fusión presentado.

    Tripanosomiosis americana. Se estima que más del 90% de los investigadores utilizan actualmente enfoques y herramientas moleculares en sus proyectos de investigación. El auge de la biología molecular en el caso particular de la parasitología o de la medicina tropical es la consecuencia de la aplicación de métodos refinados para estudiar regiones específicas del genoma de los organismos con los cuales los investigadores identifican la variabilidad genética de las poblaciones naturales del parásito y buscan las posibles correlaciones con los ciclos epidemiológicos, con la sintomatología clínica, la potogenicidad, la susceptibilidad o resistencia al tratamiento.

    El análisis de isonezimas fue el primer abordaje de caracterización bioquímica de las cepas de T. cruzi llevado a cabo por Miles et al., 1977, 1978, 1980 que permitió identificar la existencia de tres zimodemos (Z1, Z2 y Z3. Numerosos estudios realizados posteriormente, mostraron la correlación entre los zimodemos Z1 y Z3 con los ciclos de transmisión silvestre de T. cruzi y Z2 con los ciclos de transmisión doméstica. La mayoría de cepas de T. cruzi caracterizadas por isoenzimas en Colombia han sido aisladas de vectores y reservorios silvestres y algunas pocas de humanos. Varios trabajos realizados durante los últimos 15 años, revelan el predominio en nuestro territorio de los zimodemos Z1 y Z3 (Widmer et al., 1985; Ebert, 1985; Saravia et al., 1987; Triana, 1995; Márquez et al., 1997; Montilla, 1995; Montilla et al., 1997. Recientemente, Devia (1999, analizó 25 aislados humanos de T. cruzi de diferentes regiones geográficas encontrando 20 de ellos correspondientes al zimodemo Z1 y cinco al zimodemo Z3.

    Full Text Available Durante os anos de 1982 a 1986, a investigação sobre mamíferos comensais e silvestres, da periferia da cidade de Jacobina, Bahia, mostrou, ao lado do escasso número de exemplares, uma reduzida variedade específica dessa fauna. Capturou-se apenas 11 espécies, entre as quais, predominou o Didelphis albiventris, que abrangeu 44% dos 213 espécimens capturados. Entre os 193 com exames já concluídos, 84 eram exemplares de D. albiventris e 2 estavam infectados pela Leishmania donovani senso lato, 1 por L. mexicana amazonensis, 1 por L. braziliensis, subespécie e 3 por Trypanosoma cruzi Também foram observadas formas suspeitas de serem amastigotas de leishmanics, nos esfregaços de órgãos de 3 exemplares de Dasyprocta aguti, 1 Cercomys cunicularius - e 1 Oryzomys eliurus. 0 restante dos exemplares, inclusive 14 de Lycalopex vetulus, estava negativo para flagelados. Apesar de reforçado por outros indicadores epidemiológicos, como a predominância específica, a freqüência domiciliar, a atratividade para a vetora Lutzomyia longipalpis, e a concomitância com casos humanos nos mesmos locais, o índice de 2,3% de infecção natural do Didelphis albiventris, não autoriza a conclusão definitiva de ser o marsupial o mais importante reservatório natural da leishmaniose visceral em Jacobina.

    2011-07-01

    Full Text Available El presente trabajo es la primara aproximación acerca del papel de las plantas con órganos de almacenamiento subterráneos comestibles (POAS en la Patagonia, desde una perspectiva temporal y espacial, al integrar datos etnohistóricos y etnográficos actuales ligados al uso de las POAS. El 75 % de las 54 fuentes analizadas mencionan el uso de POAS en la alimentación humana de la Patagonia. Las POAS silvestres comestibles registradas ascienden a 51 especies, siendo mayor el conjunto de POAS con raíces comestibles. La estepa y zonas ecotonales resultaron las de mayor riqueza de POAS, probablemente vinculado a adaptaciones ecológicas de éstas a la aridez en el primer caso, como a la alta diversidad relativa que presentan los ecotonos, en el segundo. El registro etnohistórico mostró discontinuidades marcadas, siendo pocas las especies presentes por más de un siglo, destacándose la continuidad documental de A. tuberosa desde el siglo XVIII al presente, así como la incorporación reciente de especies exóticas. Las fuentes etnohistóricas revisadas y su contraste con datos etnobotánicos recientes de campo sugieren dinamismo en los patrones de utilización, que a lo largo del tiempo han llevado al abandono del uso de las POAS en la práctica alimentaria de la Patagonia. Las singularidades encontradas respecto a lo temporal y espacial pueden vincularse tanto a los conocimientos locales y específicos desarrollados a lo largo del tiempo por los habitantes de la Patagonia, como también a las circunstancias sociopolíticas y académicas de cada una de las fuentes analizadas.

    En Colombia la rabia ocurre en dos ciclos epidemiológicos principales: la rabia urbana con el perro como principal reservorio y transmisor principalmente a humanos, y la rabia silvestre con especies animales de la vida silvestre como los quirópteros y zorros entre otros, como reservorios y transmisores principalmente a especies ganaderas y eventualmente a humanos que se convierten en víctimas accidentales. Durante los últimos años la rabia silvestre en Colombia ha cobrado mayor relevancia como problema de salud pública que la rabia urbana, a juzgar por el número de víctimas humanas. Con el fin de perfeccionar el diagnóstico y la tipificación del virus de la rabia en Colombia, el Laboratorio Nacional de Referencia del Instituto Nacional de Salud estandarizó técnicas para amplificar y secuenciar un fragmento de ADN complementario (cADN a una fracción de 902 nucleótidos seleccionados del ARN del virus, con el fin de adelantar estudios de epidemiología molecular. La fracción mencionada contiene secuencias que codifican para los aminoácidos 447-525 de la glicoproteína y 1-35 de la proteína L. Además contiene la región intergénica no codificante conocida como Pseudogen Psi.

    Las técnicas estandarizadas fueron las siguientes: a extracción de ARN total a partir de cerebro de ratón infectado. b amplificación molecular por transcripción reversa y reacción en cadena de la polimerasa. c secuenciación del fragmento amplificado.

    Mediante estas técnicas de epidemiología molecular viral se determinó que durante 1994-2004, la rabia urbana se concentró en tres regiones geográficas definidas, con epizootias en el antiplano cundiboyacense, departamento de Arauca y la región Caribe. Las dos primeras se controlaron

    Full Text Available En agosto de 1934 el Padre Francisco Savary, misionero de la Compañía Montfort, da la voz de alarma acerca de unos casos de fiebres que se han presentado en unas veredas del vecindario de Restrepo y cuyo cuadro clínico corresponde al descrito en el capítulo de fiebre amarilla de su Manual de Misionero. Se practica una primera investigación encontrando, en efecto, manifestaciones mórbidas que sugieren fiebre amarilla. El brote presenta una característica extraña que confunde a primera vista la investigación, en un momento en que la noción de la fiebre silvestre, o sea sin Aedes aegypti, no está aún generalizada. No se encuentra tal zancudo en la región. A consecuencia de un informe de la Dirección Nacional de Higiene, el Dr. E. R. Rickard, médico de la Fundación Rockefeller, baja a Villavicencio y me deja instrucciones precisas, con elementos de investigación. En esta época el autor era Director Intendencial de Higiene. Se toman 30 muestras de sangre distribuídas entre personas convalecientes de ataques de la enfermedad, entre personas que moraban en las casas en que habían ocurrido casos y entre compañeros de trabajo de personas atacadas. De las muestras sometidas a la prueba de inmunidad para fiebre amarilla, 20 resultaron positivas, 2 inconclusivas y 8 negativas. Estos resultados traen por consecuencia el establecimiento de una comisión de investigación epidemiológica en la región de Restrepo.

Las abejas fueron colectadas en el estrato herbáceo de la Reserva Universitaria “Escuela Granja” de la localidad Esperanza, y en la zona urbana de la localidad Susana, ambas ubicadas dentro de la Provincia Fitogeográfica del Espinal. La colecta se realizó en octubre, noviembre y diciembre de 2004 y en enero, febrero y marzo de 2005, registrando las especies vegetales sobre las que se capturaron. Se colectaron 277 ejemplares en total, de los cuales se identificaron 62 especies (27 géneros en 5 familias. Las curvas de rarefacción indican una tasa de acumulación de especies mayor para la Reserva Ecológica, los índices de diversidad de Shannon son 3,25 para la Reserva Ecológica y 2,64 para la Zona Urbana. Para la comparación de las comunidades en ambos sitios, las abejas fueron clasificadas en tres categorías según la especialización en el uso del recurso floral, sustrato de nidificación y comportamiento social. Se observó una asociación entre los grupos especialistas y de nidificación en el suelo con el ambiente natural, y por otro lado, las especies generalistas y de nidificación en cavidades con el ambiente urbano. No se identificaron diferencias, en cuanto al tipo de comportamiento social de las especies, entre ambos sitios.

Se generó un modelo de simulación determinístico que representa la dinámica de poblaciones silvestres de chigüiros, como resultado de procesos biológicos de natalidad y mortalidad, y del aprovechamiento extractivo anual de individuos en hatos de los municipios de Paz de Ariporo y Hato Corozal (Casanare, Colombia. Una interfase fue diseñada para facilitar el uso del modelo y construir escenarios para simular diferentes alternativas de manejo. El modelo fue usado para evaluar el efecto a largo plazo de la cosecha o extracción de individuos mediante la caza comercial, la cosecha selectiva de adultos por sexos, la presencia de adecuaciones y la variación del área de hábitat adecuado disponible sobre la tendencia de abundancia de tres poblaciones silvestres de chigüiros en la zona de estudio. Las simulaciones realizadas bajo los diferentes escenarios permitieron establecer las distintas respuestas de cada población a los cambios realizados en la tasa de cosecha y el área de hábitat y así recomendar acciones de manejo. Los escenarios evaluados destacan la importancia de hacer una extracción selectiva de adultos por sexos para realizar un aprovechamiento sostenible de la población y garantizarsu conservación. Así mismo, se destaca la importancia de mantener mayores áreas con hábitat adecuado.

    Full Text Available Apresentaram-se os resultados das observações sobre o comportamento de formas adultas de Culicidae silvestres na área de Casa Grande, de zona de florestas primitivas situada na parte nordeste do Estado de São Paulo, Brasil. As investigações focalizaram os mosquitos de hábitos diurnos e crepusculares-noturnos, durante o período de 1963 a 1966. Foram obtidos dados concernentes à composição especifica, distribuição, ciclo anual da densidade, estratificação vertical na floresta e possíveis relações com o ambiente doméstico. A região estudada é considerada como bioma ou ecossistema do Anopheles (Kerteszia cruzii e, dessa maneira, êsse mosquito compareceu de maneira predominante nas observações, merecendo por isso especial atenção. As outras espécies distribuiram-se predominantemente entre os Sabethini, além de alguns Culicini. No que concerne à domesticidade, o Anopheles cruzii apresentou-se como apreciável freqüentador das casas, seguido pelo Aedes serratus. Além disso, aquele anofelino mostrou-se acentuadamente acrodendrófilo, parecendo ser dotado de alguma ornitofilia.This work reports observations on adult Culicidae activities for diurnal and crepuscular-nocturnal forest species occurring in the area of Casa Grande, located at the Northeast region of the State of São Paulo, Brazil. These investigations, were carried out during the 1963 to 1966 period. They recorded the specific composition, distribution, year cycle of abundance, vertical stratification in the forest, and the possible relationship of these forest mosquitoes to the housekold environment. Since these region is considered a biome of the Anopheles (Kerteszia cruzii particular attention was dedicated to this species, considered as an important malaria vector. Beside this, several Sabethini species proved to be considerably abundant and, along with some culicines as Aedes serratus, showed activities that may put these mosquitoes in relation with humans

As amostras foram coletadas ao longo do ano 2000, a partir de coletas realizadas por apicultores, associações e cooperativas de apicultura da região abrangida pelos municípios de Picos, Itainópolis, Vera Mendes e Isaías Coelho. Após as coletas as amostras passaram pelos processos de centrifugação, filtragem e decantação. As medidas reológicas foram feitas nas temperaturas de 20 a 40 ºC utilizando-se um viscosímetro Brookfield, modelo RVT. As leituras de velocidade de rotação e torque foram transformadas em valores de taxa de deformação e tensão de cisalhamento. Os dados de taxa de deformação e tensão de cisalhamento foram ajustados pelas equações da Lei-da-Potência e de Herschel-Bulkley. As amostras apresentaram comportamento pseudoplástico. As equações se ajustaram adequadamente aos resultados experimentais de tensão de cisalhamento em função da taxa de deformação. O aumento de temperatura reduziu a viscosidade aparente em níveis próximos de 80%. Os valores de viscosidade aparente foram bem ajustados por uma equação do tipo Arrhenius.The rheological behavior of Apis mellifera honey produced in the State of Piauí, in the Brazilian semi-arid, obtained with predominance of Serjania glabrata flowers was studied. The samples were collected in the year 2000 by beekeepers and associations and cooperatives of beekeepers in the area covered by the municipal districts of Picos, Itainópolis, Vera Mendes and Isaías Coelho. The samples were centrifuged, filtered, decanted and the rheological measures at temperatures of 20 to 40 ºC using a Brookfield Viscometer RVT model were made. The readings of rotation speed and torque were transformed in shear rate and shear stress values. The data of shear rate and shear stress were fitted

    Full Text Available Abstract: In Brazil, ever since colonization plants have been used as natural products; thus, the National Health Surveillance Agency has been establishing rules for herbal medicine regulation; in this light, 71 plant species were chosen and empirically used in the country to investigate their medicinal properties. Currently, 12 of these 71 plants have been approved to be used in SUS (Public Health System, the remaining species still need further research. Thusly, this review aimed to seek information from toxicological studies on the plants that have not yet been officially approved, to stimulate new research in the field, promoting an economical and functional impact. In order to obtain the information, the keywords plant name + toxicity and/or toxicological studies were searched in the most prominent databases, both in English and in Portuguese. The ten plants with the most references were included in this review. Among the ten plants assessed, three have all the required studies required by the National Health Surveillance Agency, two of which we recommend the immediate adoption by SUS. In general, three plants have a determined LD50, nine have reproductive toxicity data, and five have not yet shown any sign of toxicity.

    2008-06-01

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

    Full Text Available The productive cycle of Scots pine (Pinus sylvestris L. and black pine (Pinus nigra Arn. within the medieval Castilian and Andalusian carpentry is here analysed. New criteria to identify both timbers and its dendrochronological date are shown as previous facts to determine their geographical origin. Historical names of these species and other names, such as alerce, with a vague allocation are also studied. Main historical areas of resource and river ways of Tajo and Guadalquivir used to transport the wood (black pine to interior cities (Sevilla, Toledo, Madrid … are thus identified. On the other hand, wood’s diversification and its selective use is analysed regarding its resistance value. Availability also determines that a sort of wood becomes fossil-guide (especie-guía, which is proposed as chronological indicator for several periods and constructive contexts. Some timber remains dating to the first millennium are studied in detail. They belong to the Mosque of Cordoba and four early medieval churches sited in the Duero valley (La Nave, Baños, Quintanilla and Barriosuso. The empiric dating and analysis of this material offer a post quem chronology for the building of these churches and new facts about the distribution of theses wood’s species in the north-western Iberian peninsula.Se realiza un recorrido a través del ciclo constructivo de las maderas de pino silvestre (Pinus sylvestris L. y pino laricio (Pinus nigra Arn. en el ámbito de la carpintería medieval de Castilla y Andalucía.

    Full Text Available Durante os anos de 1982 a 1986, a investigação sobre mamíferos comensais e silvestres, da periferia da cidade de Jacobina, Bahia, mostrou, ao lado do escasso número de exemplares, uma reduzida variedade específica dessa fauna. Capturou-se apenas 11 espécies, entre as quais, predominou o Didelphis albiventris, que abrangeu 44% dos 213 espécimens capturados. Entre os 193 com exames já concluídos, 84 eram exemplares de D. albiventris e 2 estavam infectados pela Leishmania donovani senso lato, 1 por L. mexicana amazonensis, 1 por L. braziliensis, subespécie e 3 por Trypanosoma cruzi Também foram observadas formas suspeitas de serem amastigotas de leishmanics, nos esfregaços de órgãos de 3 exemplares de Dasyprocta aguti, 1 Cercomys cunicularius - e 1 Oryzomys eliurus. 0 restante dos exemplares, inclusive 14 de Lycalopex vetulus, estava negativo para flagelados. Apesar de reforçado por outros indicadores epidemiológicos, como a predominância específica, a freqüência domiciliar, a atratividade para a vetora Lutzomyia longipalpis, e a concomitância com casos humanos nos mesmos locais, o índice de 2,3% de infecção natural do Didelphis albiventris, não autoriza a conclusão definitiva de ser o marsupial o mais importante reservatório natural da leishmaniose visceral em Jacobina.From 1982 to 1986, investigations on the natural infection with leishmanias of the sylvatic and commensal mammals were carried out around the city of Jacobina, Bahia, one of the oldest endemic foci of visceral leishmaniasis in Brazil. The species of Marsupialia Didelphis albiventris predominated, with the rate of 44%, over the total of 213 specimens belonging to only 11 different species of mammals collected there. Among the 84 specimens of D. albiventris examined, 2(2.3% were infected with Leishmania donovani sensu lato; 1 with L. mexicana amazonensis, 1 with L. braziliensis sub species, and 3 with Trypanosoma cruzi.

    Full Text Available Groundnut (Arachis hypogaea has an AB genome and is one of the most important oil crops in the world. The main constraints of crop management in Brazil are fungal diseases. Several species of the genus Arachis are resistant to pests and diseases. The objective of our experiments was to identify wild species belonging to the taxonomic section Arachis with either A or B (or " non-A" genomes that are resistant to early leaf spot (Cercospora arachidicola, late leaf spot (Cercosporidium personatum and rust (Puccinia arachidis. For the identification of genotypes resistant to fungal diseases, bioassays with detached leaves were done in laboratory conditions, with artificial inoculation, a controlled temperature of 25ºC and a photoperiod of 10 h light/14 h dark, for 20-42 days, depending on the fungi species. Most of the accessions of wild species were more resistant than accessions of A. hypogaea for one, two or all three fungi species studied. Arachis monticola, considered to be a possible tetraploid ancestor or a derivative of A. hypogaea, was also more susceptible to Cercosporidium personatum and Puccinia arachidis, as compared to most of the wild species. Therefore, wild germplasm accessions of both genome types are available to be used for the introgression of resistance genes against three fungal diseases of peanut.O amendoim (Arachis hypogaea possui genoma AB e é uma das mais importantes culturas oleaginosas em todo o mundo.

    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.

    2015-01-01

    Microstructural damage and nano hardness of the industrial grade stainless steel (SUS-316) have been studied under proton (H + ) 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

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

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.

    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 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.

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.

    Genomic differences between gut-resident bacterial strains likely underlie significant interindividual variation in microbiome function. Traditional methods of determining community composition, such as 16S rRNA gene amplicon sequencing, fail to capture this functional diversity. Metagenomic approaches are a significant step forward in identifying strain-level sequence variants; however, given the current paucity of biochemical information, they too are limited to mainly low-resolution and incomplete functional predictions. Using genomic, biochemical, and molecular approaches, we identified differences in the fructan utilization profiles of two closely related Bacteroides thetaiotaomicron strains. B. thetaiotaomicron 8736 ( Bt-8736 ) contains a fructan polysaccharide utilization locus (PUL) with a divergent susC / susD homolog gene pair that enables it to utilize inulin, differentiating this strain from other characterized Bt strains. Transfer of the distinct pair of susC / susD genes from Bt-8736 into the noninulin using type strain B. thetaiotaomicron VPI-5482 resulted in inulin use by the recipient strain, Bt ( 8736-2 ). The presence of the divergent susC / susD gene pair alone enabled the hybrid Bt ( 8736-2 ) strain to outcompete the wild-type strain in vivo in mice fed an inulin diet. Further, we discovered that the susC / susD homolog gene pair facilitated import of inulin into the periplasm without surface predigestion by an endo-acting enzyme, possibly due to the short average chain length of inulin compared to many other polysaccharides. Our data builds upon recent reports of dietary polysaccharide utilization mechanisms found in members of the Bacteroides genus and demonstrates how the acquisition of two genes can alter the functionality and success of a strain within the gut. IMPORTANCE Dietary polysaccharides play a dominant role in shaping the composition and functionality of our gut microbiota. Dietary interventions using these m icrobiota- a

    Full Text Available El Perú es el principal abastecedor de “tara”, gracias a que nuestro país posee una gran variedad de climas y tipos de suelos, haciendo posible la obtención de este cultivo durante la mayor parte del año. El departamento de Junín cuenta con poblaciones naturales de “tara” que aun no han sido caracterizadas bioquímica ni genéticamente, que podrían aprovecharse en beneficio de las comunidades locales. En este trabajo se reporta la capacidad antioxidante de “tara” provenientes de las localidades de Picoy y Santa Fe, ambas ubicadas en Tarma, Junín. Se utilizó la técnica del DPPH y del ABTS para valorar la capacidad antioxidante; para la determinación de fenoles y flavonoides se utilizó el reactivo de Folin-Ciocalteau según la técnica de Singleton. La muestra de Picoy reportó mayor cantidad de fenoles siendo de 563.70 mg/g de extracto seco, mientras que la cantidad de flavonoides fue de 0.664 mg/g. La capacidad antioxidante mostro una mejor respuesta en la muestra de Picoy, reportándose mediante el DPPH un IC50 1.244 mg/ml y con el ABTS un 35.3% de inhibición. Estos datos podrían aprovecharse para incrementar el valor agregado y mejorar la oferta de este recurso en dicha localidad debido a sus mejores características antioxidantes.

    Thermo-mechanical treatment was given to improve further the superplastic behavior of SUS 304 stainless steel. In the SUS 304, martensite phase produced by the processing induced transformation may be reversely transformed to the primary austenite phase by high-temperature heating. Crystal grain size is micronized to 1 {mu} m by combining this reverse transformation and recrystallization of the austenite phase. However, the straining rate at that time is as extremely low as 1 times 10 {sup -4}/s or lower, which is insufficient for an industrial material. Therefore, the SUS 304 processed as described above was given again a series of thermo-mechanical treatment of the similar forced cold processing and annealing to ultra-micronize the crystalline particles. Majority of the crystalline particles have come to have a grain size of several hundred nm. This test piece showed a total elongation of 400% or more at a test temperature of 973 K and a straining rate of 1.8 times 10 {sup -3}/s or lower. In addition, the straining rate sensitivity index `m` at that time was 0.45 or higher. The superplastic deformation of the SUS 304 has a high possibility of being governed by dynamic recrystallization. 4 refs., 7 figs., 1 tab.

Describimos en este artículo las enfermedades por anisakis, los trabajos de riesgo, las características que debieran reunir para ser enfermedad profesional y dos casos ilustrativos cuya consideración lo fue como esta contingencia laboral. Conclusión: Las enfermedades por anisakis y su consideración como enfermedad profesional, viene sujeta a la propia definición de lo que se considera así en nuestra norma legal, es decir que sea una enfermedad contraída como consecuencia del trabajo, en las actividades que se describen en el cuadro de enfermedades profesionales y por la acción del agente o sus sustancias que se recogen en el anexo I del actual cuadro. Además para que se admita como enfermedad profesional debemos de tener un diagnóstico firme (encuadrado en el cuadro de enfermedad profesional, un agente causal (recogido en el listado y una exposición al anisakis desarrollada en el ejercicio del trabajo (actividades recogidas en el listado. El listado o cuadro de enfermedad profesional es un sistema cerrado para agentes causales y enfermedades causadas, y la adscripción no es fácil. La parasitación tendría cabida en el grupo de enfermedades por agentes biológicos, la alergia podría discutirse su adscripción pero suele recogerse también en este grupo, el asma lo recogeríamos en el grupo de enfermedades respiratorias (causadas por inhalación dice el texto legal y las manifestaciones dérmicas en el grupo de las enfermedades profesionales de la piel. La exposición laboral al anisakis, es necesaria e imprescindible para que el proceso sea calificado de enfermedad profesional, pero esta exposición no siempre estará bien delimitada, y sin embargo debe estar probada. Puede haber existido una sensibilización fuera del trabajo y una aparición o desarrollo de la enfermedad por reiterada exposición o contacto con el anisakis en el trabajo lo que dificultará su calificación ocupacional.

    Full Text Available Population growth poses threats to biodiversity, specifically to sensitive species. Therefore, an understanding of the conflict between biodiversity and human population is needed to enable long-term planning of development and conservation policies by state and federal governments and society based on limitations and potentials of environments. We used a geopolitical approach to analyze data on human demography, economic activities, natural vegetation, avian diversity, and protected areas of the 32 states of Mexico and the 30 districts of the state of Oaxaca. Using factor analysis, we identified the biodiversity-rich geopolitical units that have a large human population and are developing intense economic activities. We then carried out a series of linear regressions between the resulting factors to test whether they were related, suggesting areas where conservation conflicts may exist, and found that relations between human activities and natural resources vary from region to region. These results help us identify geopolitical units that require detailed studies of the interactions between population and natural resources, and also highlight the importance of using geopolitical scales as study units, where most conservation and development policies are determined, to inform local stakeholders and decision makers.El crecimiento humano representa amenazas para la biodiversidad, especialmente para especies sensibles. Se necesita conocer a fondo el conflicto que representa el crecimiento de la población para la biodiversidad y llevar a cabo políticas y acciones a largo plazo de actividades de desarrollo y conservación evaluadas por gobiernos federales y estatales, basándose en las limitaciones y potenciales de los ecosistemas. Utilizamos una aproximación geopolítica para analizar variables de demografía humana, actividades económicas, superficie de vegetación, diversidad de aves y áreas protegidas de los 32 estados de México y los 30 distritos de Oaxaca. Mediante un análisis de factores, identificamos las entidades geopolíticas con más biodiversidad con alta población humana y que desarrollan intensamente actividades económicas. Posteriormente realizamos regresiones lineales entre los factores para analizar su interrelación, lo que sugiere áreas en las que la conservación está amenazada, encontrando que estas relaciones varían en cada región. Estos resultados identifican las unidades geopolíticas que requieren un estudio detallado de la interacción entre población y recursos naturales y resaltan la importancia de utilizar una escala geopolítica, que es el nivel donde se determinan la mayor parte de las políticas de conservación y desarrollo, para proveer información detallada a usuarios y tomadores de decisiones.

    Full Text Available El parvovirus canino tipo 2 (CPV-2 es el agente causal de una enfermedad infecto-contagiosa que produce una gastroenteritis aguda hemorrágica que afecta a caninos jóvenes. El CPV-2 se adaptó a la especie canina por mutación del virus de la Panleucopenia felina (FPV luego de su paso por animales silvestres como el hurón y los zorros. La alta variabilidad de la proteína viral 2 (VP2 es la causa principal del amplio rango de hospedadores y de las reacciones cruzadas entre las variantes. En la actualidad, la secuenciación de esta proteína ha permitido identificar tres variantes del virus conocidas como 2a, 2b y 2c que conviven en el mundo con diferencias en tropismo celular, infecciocidad y patogenicidad. El virus ssADN ha presentado una gran variación génica en cortos períodos de tiempo lo que indica un alto grado de selección por evolución sólo comparable con virus RN, esta alta variabilidad no se ha aclarado totalmente. El empleo de las técnicas moleculares permitirá diferenciar entre cepas vacunales y de campo, tanto como contar con técnicas diagnósticas confiables y específicas.

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

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

    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.

    SUS-MI cables are the inorganic insulation cables using austenitic stainless steel SUS 321 as the sheath, oxygen-free copper as the conductor and high purity magnesium oxide as the insulatingmaterial. Because of the excellent characteristics of the composing materials, the properties withstanding radiation, fire and heat, and sodium of the cables are superior. In the nuclear power facilities being developed such as fast breeder reactors and nuclear fusion reactors, there is the environment the cables with organic materials as the components cannot meet. As the cables to be applied to such places, the SUS-MI cables are most suitable. In this report, the electric properties and the mechanical strength of the cables and the examples of practical use are described. The highest temperature of using the SUS-MI cables is 800 deg C. The form and the composing materials of the SUS-MI cables, the characteristics and the cable laying are reported. Ceramic connectors and heat-resistant wall penetration parts were developed. The characteristics of the cables for the preheaters of fast breeder reactors are compared. (Kako, I.)

La altura promedio de los árboles fue de 16.6 ± 4.4 m y el diámetro 43.2 ± 11.5 cm. La preferencia del guajolote silvestre por utilizar pinos como dormideros en lugar de otras especies arbóreas, se debe posiblemente a que son árboles de mayor porte o a la conformación de su dosel; sin embargo, se ha observado que en lugares donde hay pocos pinos, los guajolotes utilizan para dormir otros árboles de características semejantes, como encinos, madroños o sicomoros.Sixteen roosting sites of Gould's wild turkey (Meleagris gallopavo mexicana were found between October and November of 2001 and May of 2002 in Sierra Fría, Aguascalientes.

Un total de 723 plántulas se transplantaron al campo y se evaluaron morfológicamente durante todo su ciclo biológico, con un descriptor que incluyó 20 caracteres cuantitativos y 25 cualitativos. Se estimó la variabilidad morfológica y se detectaron diferencias fenotípicas relacionadas con el fruto, características vegetativas de las plantas y los componentes del rendimiento. Las variables morfológicas mostraron que S. habrochaites es la especie más diferenciada con relación a las restantes. La podredumbre vascular causada por F. oxysporum es responsable de enormes pérdidas en la producción de tomate en el mundo; sin embargo, las especies silvestres que originaron las variedades cultivadas poseen genes de interés agronómico, utilizados por décadas para la generación de variedades resistentes. Por ello, entre 64 y 228 individuos por especie, se evaluaron por tres procedimientos de inoculación. Todas las especies fueron significativamente diferentes en los niveles de resistencia, tolerancia o susceptibilidad. S. neorickii fue más resistente y tolerante, seguida de S. pimpinellifolium y S. lycopersicum var. cerasiforme, mientras que todas las variedades cultivadas (S. lycopersicum fueron susceptibles. Tales circunstancias permitieron determinar sin lugar a dudas, que las plantas sobrevivientes y tolerantes poseen un genotipo particular que determina esa característica.

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

    Highlights: • The role of oxide particles in α/α′ phase decomposition behavior; microstructure of phase decomposition observed by TEM. • The characteristics of ductility loss caused by age-hardening. • Correlation of phase decomposition and age-hardening explained by dispersion strengthened models. • Age-hardening susceptibility of ODS steels and SUS430 steel. - Abstract: The effect of aging on high-Cr ferritic steels was investigated with focusing on the role of oxide particles in α/α′ phase decomposition behavior. 12Cr-oxide dispersion strengthened (ODS) steel, 15Cr-ODS steel and commercial SUS430 steel were isothermally aged at 475 °C for up to 10,000 h. Thermal aging caused a larger hardening in SUS430 than 15Cr-ODS, while 12Cr-ODS showed almost no hardening. A characteristic of the ODS steels is that the hardening was not accompanied by the significant loss of ductility that was observed in SUS430 steel. After aging for 2000 h, SUS430 steel shows a larger ductile–brittle transition temperature (DBTT) shift than 15Cr-ODS steel, which suggests that the age-hardening susceptibility is lower in 15Cr-ODS steel than in conventional SUS430 steel. Thermal aging leaded to a large number of Cr-rich α′ precipitates, which were confirmed by transmission electron microscopy (TEM). Correlation of age-hardening and phase decomposition was interpreted by Orowan type strengthening model. Results indicate that oxide particles cannot only suppress ductility loss, but also may influence α/α′ phase decomposition kinetics.

    Full Text Available Introduction: between 2000 to 2011, Diadema paulista municipality has faced many obstacles in health management, struggling to ensure the sustainability of its health system. Objective: to contribute to the discussion of the Unified Health System (SUS and its foreseable turbulent future, based on the analysis of the municipal point of view, identifying the limits of its building in Diadema. Methods: Diadema is characterized as one of the first municipalities that adhered to the principles of the SUS, since its implementation, allowing an analysis as a case study in view of the system's sustainability at the local level. The term sustainability used was addressed in two dimensions: the structure of this system and its process. Results: in SUS implementation period, Diadema stood out by increasing investment in health, reaching an average allocation of about 30% of its tax revenues, including constitutional transfers. Results diagnosed by observing the structure of dimensions and the process indicate that the sustainability of the municipal health system is threatened, as the significant expansion of the range of services and health actions was not followed by sufficient resources to its health maintenance. Conclusions: the existence of obstacles justified and formed the basis for the diagnosis of the main limits on SUS conformation, in health policy and management of resources, funding and budgetary impacts.

    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.

  19. The insulin-like growth factor 2 (IGF2) gene intron3-g.3072G>A polymorphism is not the only Sus scrofa chromosome 2p mutation affecting meat production and carcass traits in pigs: evidence from the effects of a cathepsin D (CTSD) gene polymorphism.

    The objective of this study was to evaluate the effects of mutations in 2 genes [IGF2 and cathepsin D (CTSD)] that map on the telomeric end of the p arm of SSC2. In this region, an imprinted QTL affecting muscle mass and fat deposition was reported, and the IGF2 intron3-g.3072G>A substitution was identified as the causative mutation. In the same chromosome region, we assigned, by linkage mapping, the CTSD gene, a lysosomal proteinase, for which we previously identified an SNP in the 3'-untranslated region (AM933484, g.70G>A). We have already shown strong effects of this CTSD mutation on several production traits in Italian Large White pigs, suggesting a possible independent role of this marker in fatness and meat deposition in pigs. To evaluate this hypothesis, after having refined the map position of the CTSD gene by radiation hybrid mapping, we analyzed the IGF2 and the CTSD polymorphisms in 270 Italian Large White and 311 Italian Duroc pigs, for which EBV and random residuals from fixed models were calculated for several traits. Different association analyses were carried out to distinguish the effects of the 2 close markers. In the Italian Large White pigs, the results for IGF2 were highly significant for all traits when using either EBV or random residuals (e.g., using EBV: lean cuts, P = 2.2 x 10(-18); ADG, P = 2.6 x 10(-16); backfat thickness, P = 2.2 x 10(-9); feed:gain ratio, P = 2.3 x 10(-9); ham weight, P = 1.5 x 10(-6)). No effect was observed for meat quality traits. The IGF2 intron3-g.3072G>A mutation did not show any association in the Italian Duroc pigs, probably because of the small variability at this polymorphic site for this breed. However, a significant association was evident for the CTSD marker (P production traits in Italian Duroc pigs (lean content, ADG, backfat thickness, feed:gain ratio) after excluding possible confounding effects of the IGF2 mutation. The effects of the CTSD g.70G>A mutation were also confirmed in a subset of Italian Large White animals carrying the homozygous genotype IGF2 intron3-g.3072GG, and by haplotype analysis between the markers of the 2 considered genes in the complete data set. Overall, these results indicate that the IGF2 intron3-g.3072G>A mutation is not the only polymorphism affecting fatness and muscle deposition on SSC2p. Therefore, the CTSD g.70G>A polymorphism could be used to increase selection efficiency in marker-assisted selection programs that already use the IGF2 mutation. However, for practical applications, because the CTSD gene should not be imprinted (we obtained this information from expression analysis in adult skeletal muscle), the different modes of inheritance of the 2 genes have to be considered.

    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

    This review focuses only on specific studies into the SUS regionalization process, which were based on empirical results and published since 2006, when the SUS was already under the aegis of the Pact for Health framework. It was found that the regionalization process is now underway in all spheres of government, subject to a set of challenges common to the different realities of the country. These include, primarily, that committee-structured entities are valued as spaces for innovation, yet also strive to overcome the bureaucratic and clientelist political culture. Regional governance is further hampered by the fragmentation of the system and, in particular, by the historical deficiency in planning, from the local level to the strategic policies for technology incorporation. The analyses enabled the identification of a culture of broad privilege for political negotiation, to the detriment of planning, as one of the main factors responsible for a vicious circle that sustains technical deficiency in management.

  3. Biochemical and Molecular Characterization of RcSUS1, a Cytosolic Sucrose Synthase Phosphorylated in Vivo at Serine 11 in Developing Castor Oil Seeds*

    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 32Pi from [γ-32P]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. PMID:25313400

    The behavior of martensitic transformation due to plastic deformation at room temperature was investigated in SUS304 austenitic stainless steels with the same nickel equivalent. The absolute volume of the martensitic phase was obtained by saturation magnetization. We discuss the shapes of the martensitic phase caused by different values of coercive force. Martensitic transformation depends on the applied stress but is independent of nickel content with same nickel equivalent. We investigated applications to nondestructive testing on the basis of the present study. (author)

C for up to 100 h was conducted. Optical microscopy reveals grain coarsening in both the alloys upon annealing. Observations by transmission electron microscopy revealed the precipitation of nanometer-sized spherical Cu particles distributed within the austenitic grains and the presence of carbides at the dislocations. Both the yield and ultimate tensile strengths of the alloys were found to remain invariant with annealing. Tensile ductility and the threshold stress intensity factor range for fatigue crack growth for 3 wt.% Cu added alloy increase with annealing. These are attributed to the grain coarsening with annealing. In all, the addition of Cu to SUS 304H does not affect the mechanical performance adversely while improving creep resistance.

    Santos, Lenir

    2017-04-01

    This paper describes a comprehensive effort to develop studies regarding Brazil's Unified Healthcare System (SUS), as a result of the combination of public services in a network that follows a region-based rationale (tripartite organization). The SUS emerges from such an integration and should be organized as such. The intention is to demonstrate that this type of organization is essential, given that Brazil is organized as a Federation, and all three governmental levels are, in a broad sense, equally responsible for healthcare. Healthcare services and actions are a complex set of activities that are interconnected on behalf of citizen health, which is a global concept that cannot be split up. Services must follow this rationale and be organized as such. Thus, healthcare services must be systematically organized to serve everyone equally, regardless of where a citizen lives. This systemic organization requires permanent interaction between federative units to discuss and operationalize reference services, funding and other technical and administrative aspects. These are the essential elements that make the SUS so complex and demand it be organized regionally, as a network of healthcare services.

    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 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 Following reports of two autochthonous cases of sylvatic yellow fever in the State of São Paulo, Brazil, in 2000, entomological surveys were conducted with the objective of verifying the occurrence of vector species in forest environments close to or associated with riparian areas located in the western and northwestern regions of the State. Culicidae were captured in 39 sites distributed in four regions. Haemagogus leucocelaenus and Aedes albopictus were the most abundant species and were captured in all the regions studied. H. leucocelaenus was the most abundant species in the municipalities of Santa Albertina and Ouroeste, where the two cases of sylvatic yellow fever had been reported. Mosquitoes from the janthinomys/capricornii group were only found at eight sites in the São José do Rio Preto region, while Sabethes chloropterus was found at one site in Ribeirão Preto. H. leucocelaenus showed its capacity to adapt to a secondary and degraded environment. Our results indicate a wide receptive area for yellow fever transmission in the State of São Paulo, with particular emphasis on the possibility of H. leucocelaenus being involved in the maintenance of this sylvatic focus of the disease.O registro de dois casos autóctones de febre amarela silvestre no Estado de São Paulo, Brasil, em 2000, desencadeou investigações entomológicas com o objetivo de verificar a ocorrência das espécies vetoras em ambientes florestais próximos ou associados às zonas ribeirinhas, situados nas regiões oeste e noroeste do Estado.

    Full Text Available A study was undertaken about T. sordida in the natural environment in two different regions of the state of Minas Gerais: Itapagipe (Triângulo, an area of cerrado modified by the formation of fields of pasture and agriculture, and Mato Verde (north an area of transition between caatinga and cerrado with profound deforestation in the last years due to the expansion of cotton cultivation. In both regions the principal ecotopes identified were hollow trees and the bark of live or dead trees, where the occurrence of a food source is not frequent. In this environment, the triatomines utilize various food sources; opposums appear to represent an important source of infection. In the north of Minas, a greater concentration of reservoirs and vectors was observed than in the Triángulo which could explain the higher level of infection of the triatomines in the north. Close attention to the process of domiciliation of T. sordida in the north of Minas is recommended where an extensive intervention by man in the natural environment has occurred and where a rise in the population of triatomines in the peridomestic environment has been observed in recent years.Foi realizado um estudo sobre o T. sordida em ambiente silvestre em duas diferentes regiões do estado de Minas Gerais: Itapagipe (Triângulo, área de cerrado modificado para formação de campos de pastagem e agricultura, e Mato Verde (norte uma área de transição entre a caatinga e o cerrado, profundamente desmatada nos últimos anos com a finalidade de expansão do cultivo de algodão.

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.

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.

This work aims to contribute to the debate on the inclusion of the physiotherapist in SUS (Brazil's NHS by pointing out issues that need to be deepened in future studies. Purpose: To analyze the national literature production on the relationship between the training of therapists and their work in SUS, from 1996 to 2010. Methods: Descriptive research with literature on the bases: LILACS, SCI-ELO Bank and CAPES thesis. Results: We found 13 publications, sorted by: year, publication type, region where it was published in the categories "national curriculum guidelines," "professional respon-sibility", "integrality in health" and "conceptions of teachers in training in Physiotherapy ". There no publishing from 1996 to 2005, gradually increasing from this year. It was identified a higher number of articles compared to other types of publications; there is also an important difference between the Brazilian regions, with higher prevalence of studies in the South (53.8% and a greater number of pub-lications in the category "national curriculum guidelines". Conclusion: It was possible to raise ques-tions that involve the applicability of the National Curriculum Guidelines on the pedagogical courses; suitability of teachers to the reality of SUS; investigation of the models covered in health care envi-ronments trainers, and the lack of contribution by higher education institutions on teaching-research and teaching and public service, contributing to form an important agenda of study. {#}

  8. The precipitation behavior of titanium carbide on the surface of SUS 321 stainless steel

    Yoshihara, Kazuhiro; Nii, Kazuyoshi

    1982-01-01

    The surface composition of SUS 321 stainless steel at high temperatures was observed in vacuum with Auger electron spectroscopy. The precipitation of titanium carbide was found on the surface of SUS 321. The thickness of precipitated titanium carbide layer increased in proportion to the square root of annealing time and became about 0.05 μm after heated at 1100 K for 432 ks. The precipitated titanium carbide was not replaced by the most surface active element sulfur, and remained stable on the surface. The precipitated layer, however, was not even and had many holes about 1 μm in diameter. The bottom of a hole was SUS 321, on which phosphorus, oxygen and sulfur segregated. As the annealing time was prolonged, these segregants were replaced one by one in the order of the surface activity, and finally the most surface active element, sulfur, remained on the bottom of the hole. Moreover, sulfur diffused over the outside of the hole. The precipitation of titanium carbide on the surface occurred according to the following processes: (1) The titanium and carbon which had been dissolved in the bulk diffused onto the surface of the stainless steel. (2) The titanium carbide which had been precipitated in the bulk dissolved because the concentration of titanum and carbon fell under their solubility limits in the bulk. (3) The titanium and carbon diffused onto the surface which was exposed to vacuum. (4) The titanium and carbon recombined into titanium carbide and precipitated on the surface. The growth rate of the thickness of the precipitated layer was controlled by the diffusion of titanium and carbon in the precipitated titanium carbide. (J.P.N.)

    2015-06-01

    Full Text Available O presente artigo desenvolve o tema da necessidade de se regionalizar a descentralização no sentido de aglutinar o que esta supostamente poderia ter fracionado. Ao revisitar a diretriz constitucional da descentralização os autores propõem medidas que visem sua garantia ao lado de ferramentas administrativas que permitam a formação de regiões de saúde resolutivas em pelo menos 95% das necessidades de saúde do território regional, para garantir autonomia sanitária. Os autores propõem soluções que passam pela criação de pessoas jurídicas associativas regionais, resultantes da aglutinação dos entes federativos em região de saúde. Apontam ainda o que não deu certo no Sistema Único de Saúde - SUS Brasil em razão tanto de equívocos originados nas melhores intenções, quanto do oportunismo que esses equívocos geraram. Advogam os autores a necessidade de respostas jurídico-administrativas para um SUS de caráter interfederativo tanto na sua gestão, que exige compartilhamentos, quanto no seu financiamento, que se mantém interdependente também. Concluem que o único caminho para o SUS ser nacional, é regionalizá-lo e dotar a região de saúde de todo o instrumental necessário à gestão compartilhada, interfederativa e responsável.

  11. 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.

    Full Text Available La inseguridad laboral se ha convertido en la actualidad en una de las fuentes de estrés más significativas para muchos trabajadores, siendo especialmente grave en España por las elevadas tasas de desempleo en este periodo de crisis económica. Una prolífera investigación se ha desarrollado al respecto en un intento por alcanzar un conocimiento más completo de este fenómeno. El Instituto de Psicología de los Recursos Humanos, Desarrollo Organizacional y Calidad de Vida Laboral (IDOCAL ha contribuido a esta investigación en los últimos años en varias de sus facetas más significativas. En el ámbito de sus factores determinantes se ha identificado un papel significativo de la antigüedad laboral, la empleabilidad en el mercado laboral, el subempleo, y la autoeficacia laboral. Además se han realizado hallazgos de interés en relación con la diversidad de los tipos de contrato, la inseguridad laboral y sus efectos en los trabajadores. Son de especial interés los estudios que analizan el papel interviniente de distintas variables. En este contexto, nuestros estudios han puesto de manifiesto la relevancia de variables como la justicia organizacional, el clima de justicia organizacional, el apoyo organizacional, la empleabilidad, la dependencia laboral y el distanciamiento psicológico a la hora de predecir la variabilidad en la inseguridad laboral. Por último, las aportaciones del IDOCAL han sido especialmente relevantes al plantear el análisis de la inseguridad laboral como fenómeno colectivo y mostrar cómo la experiencia colectiva de la inseguridad tenía repercusiones sobre el bienestar de los trabajadores más allá de las producidas por sus percepciones individuales. En base a esta investigación se han propuesto en el presente artículo una serie de implicaciones para la práctica profesional.

    Full Text Available Este artigo analisa o grau de progressividade dos tributos que financiam o Sistema Único de Saúde (SUS. Nele são identificados os principais tributos que financiam o SUS e, com base nos microdados da Pesquisa de Orçamentos Familiares 2002-2003, é inferida a distribuição do ônus do pagamento dos tributos diretos e indiretos que financiam o SUS e analisado o grau de progressividade dos mesmos. Foi, ainda, calculado o índice de Kakwani do financiamento do SUS, que sintetiza o grau de progressividade de um sistema tributário. Os dados mostraram que o índice de Kakwani do financiamento público é de ­0,008 e que, portanto, o financiamento do SUS corresponde a um sistema quase proporcional, que onera proporcionalmente à renda. Em uma sociedade com o grau de desigualdade da brasileira, que exibe um índice de Gini de 0,57, ter um financiamento do SUS proporcional é fortemente questionável sob a ótica da justiça social: ao contrário, seria desejável construir bases de financiamento do SUS francamente progressivas, de forma a contra-restar a fortíssima concentração de renda da nossa sociedade.This article analyzes the level of progressivity in taxes financing the Brazilian Unified National Health System (SUS. Distribution of the tax burden financing the SUS was calculated using micro-data from the Household Budgets Survey, 2002-2003. The Kakwani index, which shows a tax system's level of progressivity, was calculated. The Kakwani index of public financing was -0.008, and SUS financing was nearly proportional to income. From a social justice perspective this is highly undesirable in a society like Brazil, with a Gini index of 0.57. The system should be clearly progressive in order to counterbalance the country's extreme income concentration.

    Full Text Available En esta investigación se caracterizó el potencial para la obtención de etanol a partir de la planta silvestre Cenchrus ciliaris, también conocida como zacate buffel. A partir de estudios experimentales a nivel laboratorio, se determinaron los rendimientos técnicos y requerimientos energéticos de las etapas de pretratamiento ácido, hidrólisis enzimática y fermentación. Los valores obtenidos fueron comparados con los reportados en la literatura para otros procesos de producción de combustibles. Los resultados del presente trabajo indican que el procesamiento de Cenchrus ciliaris consume la tercera parte de la energía requerida para procesar gasolina por 1 MJ de etanol producido. Asimismo, mediante este proceso es factible la reducción de las emisiones de gases de efecto invernadero por 1 MJ de energía de etanol producido en aproximadamente 40 % su valor actual.

O artigo buscou identificar a relação entre cobertura da Estratégia de Saúde da Família e o aumento de ações judiciais de insulinas análogas nas regiões Sul e Nordeste do Brasil. Nos anos 2010, 2011 e 2012, o consumo de insulinas análogas foi crescente tanto na região sul quanto nordeste. A região sul, apesar de ter um SUS organizado, IDH desenvolvido e educação estruturada, apresentou falhas no programa de diabetes. Em contrapartida, a região nordeste possui IDH baixo na maioria dos municípios e educação deficiente, porém, observou-se a necessidade de reorganização dos programas voltados ao atendimento de usuários portadores de doenças crônicas, em especial, a diabetes, nessa região. Entende-se, que o fortalecimento da atenção básica como porta de entrada para o SUS, nas regiões estudadas pode minimizar o problema da judicialização da saúde.

    Considerable amount of scale is produced by high temperature steam on the austenitic stainless steel tubes used for the superheaters and reheaters of large boilers for power generation. The scale of outer layer separates off due to the thermal stress at the time of starting-up and stopping, and causes the blocking of pipes and the erosion of turbine blades. Following the increase of nuclear power generation, large boilers are used for medium load, accordingly it is expected that the troubles like these increase. In this paper, the manufacturing method and the properties of SUS 321 HTB with fine grain internal surface are reported, which was developed to reduce the rate of growth of scale and to prevent the separation of scale. In order to prevent the separation of scale from austenitic stainless steel tubes, the reduction of scale thickness, surface treatment such as chrome plating, the use of alloys with excellent oxidation resistance, the formation of chrome-rich film rapidly, the heat treatment of cold-worked tubes and so on were carried out. The nitrification of SUS 321 H steel brought about two-phase structure of the fine grain internal surface with excellent oxidation resistance and the rest of coarse grains with high creep strength.

    This paper deals with the challenges involved in institutionalizing Monitoring and Evaluation practices within the scope of management of the Brazilian Unified Health System (SUS), based on the creation of a strategic agenda. This is structured around actions by the Federal Administration, from the perspective of defining the scope of the federative relationship. A summarized literature review is thus presented, placing into context the current SUS management process, which is based on the Pact for Health as well as theoretical and operational aspects inherent to monitoring and evaluation practices. The approach related to the strategic agenda highlights the creation of mechanisms that underpin the political and institutional decision, namely the creation of financial incentives and the development of technical mechanisms. These include organizational strategies for qualifying management teams and conducting studies and research and the dissemination of strategic information. These processes are based on the concept of providing for the management specificities in the different spheres of management based on a broad cooperation process involving teaching and research institutions and international organizations as well as the managers themselves.

Desde que se cortó esta palanca sobre la oferta crediticia, el banco central ha dependido de las operaciones de mercado abierto para lograr solamente un objetivo: influir sobre la demanda de crédito cambiando la tasa de referencia de corto plazo. La desequilibrada caja de herramientas contribuyó a un sesgo procíclico en los resultados de sus políticas que reflejó y exacerbó el sesgo procíclico del sistema financiero. El fracaso de evaluar y fortalecer sus herramientas monetarias ha socavado la habilidad de la Fed para restaurar el crecimiento económico y evitar otra crisis financiera.

    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.

In addition, its composition elements have the large (n,α) reaction cross section to high energy neutrons, and helium is apt to be generated, and this is a factor that lowers the material strength. In the He-irradiated parts in austenitic stainless steel, the precursory state of martensite transformation should exist, and its effect is considered to be observable by carrying out low temperature Moessbauer spectroscopy. As to the preparation of He-irradiation samples, the SUS 304 foils used and the irradiation conditions are described. The measurement of low temperature Moessbauer spectra for the samples without irradiation and with irradiation is reported. In order to determine the magnetic transition point, the thermal scanning measurement was carried out for the samples without or with irradiation. The martensite transformation was measured by X-ray diffraction and transmission type Moessbauer spectroscopy. In order to observe the state of the sample surfaces, the measurement by internal conversion electron Moessbauer spectroscopy was performed.

    2009-01-01

    We investigated martensitic transformation behaviour in sensitized SUS304 austenitic stainless steel to determine the stability of the austenitic phase at low temperatures. We found that a specimen that was sensitized at 973 K for 100 h exhibits an isothermal martensitic transformation when the specimen is held in the temperature range between 60 and 260 K. We constructed a time-temperature-transformation (TTT) diagram corresponding to the formation of 0.5 vol. % α'-martensite. A magnetization measurement was used to evaluate the volume fraction of a'-martensite. The TTT diagram shows a double-C curve with two noses located at about 100 and 200 K. In-situ optical microscope observations reveal that the double C-curve is due to two different transformation sequences. That is, the upper part of the C-curve is due to a direct γ → α' martensitic transformation and the lower part of the C-curve is due to a successive γ → ψ → α' martensitic transformation. The direct γ → α' transformation occurs in the vicinity of grain boundaries while the successive γ → ψ' → α' transformation occurs near the centre of grains. A scanning electron microscope observation reveals that carbide particles of M 23 C 6 are formed in the grain boundaries. The concentration difference between the centre of the grains and regions near grain boundaries is the reason for the difference in the isothermal transformation sequence for the sensitized SUS304 stainless steel.

    Full Text Available The Uni ed Health System (SUS constitutes a large technological system wi- thin the Brazilian territory since it aggregates a broad and diverse materiality in organizing and managing its ows. Additionally, it has two other attributes that make it unique: high sensibility to speci cities of different places; and technical and political centralization and decentralization of its actions. The macro dimen- sion is the SUS, leading it to be understood not simply as a health system, through its: multidimensionality – elements of other life instances (social, economic, cul- tural and political; broad and unequal spectrum of actors (state and non-state who move it and the meanings of its actions; and the trans-scaleness of its con- cretion in places (local, national and international nexuses.

Había asistido a «una conferencia sobre Filosofía de una serie tendiente a mostrar la diferencia entre la Psicología y la Lógica, que las da Ortega, y levanta el ánimo ver la cantidad y la calidad de los oyentes». No parece imposible que Unamuno hubiese escuchado parte del curso público de quince lecciones de psicología, dadas por Ortega en el otoño de 1915 y en el invierno de 1916. Curso cuyo texto incompleto había de salir publicado en 1982 con el título que le puso Paulino Garagorri, Investigaciones psicológicas. Garagorri reconocía la importancia del curso para aclarar la evolución filosófica de Ortega, pues en sus lecciones anunció su «superación del idealismo o subjetivismo». No sospechaba Garagorri, sin embargo, que el curso había de esclarecer además lo que entendía Ortega por el concepto de «superación ». Hasta ahora, la imposibilidad de saberlo ha hecho inciertas las relaciones de Ortega con sus fuentes idealistas.

Trazer o campo do real, da prática do dia a dia de profissionais, usuários e gestores mostra-se fundamental para a resolução dos problemas encontrados na assistência à saúde e para a qualificação do cuidado prestado aos sujeitos. A mudança na formação acadêmica de estudantes e professores do campo da saúde também se tem mostrado necessária. Este artigo pretende fazer uma breve recuperação histórica dos marcos das propostas de educação na saúde para profissionais do Sistema Único de Saúde (SUS, em especial no Estado de São Paulo, nos últimos anos e discutir as possibilidades de inserir metodologias ativas de ensino-aprendizagem em seu contexto. Para isso, discutimos a necessidade de aproximar a formação dos profissionais de saúde das reais necessidades dos usuários e do sistema. Isso requer mudanças institucionais, profissionais e pessoais difíceis, lentas, conflituosas e complexas. O significado da formação e a qualificação do cuidado devem estar presentes nos processos educativos para os profissionais de saúde. O ideal de profissional que queremos para o nosso Sistema de Saúde pode ser atingido se reconhecermos as necessidades e o poder criativo de cada um, ouvir o que cada um tem para dizer e refletir sobre a prática profissional inicialmente cheia de valores e de significados, os quais, muitas vezes, se perdem pelo caminho. Precisamos recuperar esses valores em nossos espaços de trabalho, nos centros formadores, nas universidades. Este é o nosso desafio.Educating professionals to work in health systems has always been a challenge. Great changes in methodologies that have been traditionally used are needed. Strategies to bring about concrete situations faced by professionals, managers and users in the real world are required to overcome problems in heath care as well as to improve the quality of the care that is provided for

    This article examines the regionalization process in the Brazilian Health System, identifying frameworks and challenges of this process from critical dialogue on the subject, contextualized by the experience of the management system and in the light of an established theoretical debate in the last decade. We used the thematic content analysis of legal and documentary surveys of the regionalization process in SUS, collated by elements of the historical and political context in the period. As evidence, it appears that the regionalization process has been incremental decentralization/deconcentration of management and health actions and services. There are important challenges, particularly in relation to ensuring access and system governance structure, which contributes to critical thinking and construction of new perspectives by those who lead their implementation.

  11. A fundamental study on stress corrosion cracking of SUS 304 steel in high temperature water

    International Nuclear Information System (INIS)

    Mukai, Yoshihiko; Murata, Masato

    1985-01-01

    SCC susceptibility of sensitized SUS 304 stainless steel in high temperature water was studied. The results obtained are as follows. SCC susceptibility was increased by adding crevices to the tensile specimen surface, for the corrodent became acidified by hydrolysis in crevices. SCC susceptibility was best fit to TTS curve obtained by EPR test, not by other corrosion tests such as Strauss test or the grain boundary corrosion test in high temperature water. In addition, by giving a simulated weld thermal cycle before the sensitizing heat treatment, the sensitization was clearly promoted. This seemed to be caused by the reason that nucleation of carbide occured in the simulated weld thermal cycle process and it promoted the carbide growth and the formation of Cr poor layer around carbide in the subsequent sensitization process.

    The microstructural changes have been examined in order to study the effect of titanium addition to type 316 stainless steels on void swelling. Titanium ions of 400 keV from an accelerator have been implanted at room temperature to solution treated SUS 316 stainless steels which have the original titanium content of 0.02 wt.% to the concentration increase of titanium by 0.01, 0.02 and 0.1 wt.%. Following the preinjection of 20 at.ppm helium at ambient temperature, 400 keV-aluminium ions have been irradiated to the specimen to 40 dpa at 550, 625 and 675 0 C. The TEM observations have revealed that the void number density is drastically increased in the specimen with the content of implanted titanium of more than 0.01 wt.%, whereas the void diameter is remarkably decreased with the titanium content.

    The mechanisms of forming nanostructured, nanophase layers are revealed and analyzed in austenitic steel subjected to surface alloying using an electron-plasma process. Nanostructured, nanophase layers up to 30 μm in thickness were formed by melting of the film/substrate system with an electron beam generated by a SOLO facility (Institute of High Current Electronics, SB RAS), Tomsk), which ensured crystallization and subsequent quenching at the cooling rates within the range 105-108 K/s. The surface was modified with structural stainless steel specimens (SUS 321 steel). The film/substrate system (film thickness 0.5 μm) was formed by a plasma-assisted vacuum-arc process by evaporating a cathode made from a sintered pseudoalloy of the following composition: Zr - 6 at.% Ti - 6 at.% Cu. The film deposition was performed in a QUINTA facility equipped with a PINK hot-cathode plasma source and DI-100 arc evaporators with accelerated cooling of the process cathode, which allowed reducing the size and fraction of the droplet phase in the deposited film. It is found that melting of the film/substrate system (Zr-Ti-Cu)/(SUS 321 steel) using a high-intensity pulsed electron beam followed by the high-rate crystallization is accompanied by the formation of α-iron cellular crystallization structure and precipitation of Cr2Zr, Cr3C2 and TiC particles on the cell boundaries, which as a whole allowed increasing microhardness by a factor of 1.3, Young's modulus - by a factor of 1.2, wear resistance - by a factor of 2.7, while achieving a three-fold reduction in the friction coefficient.

    1978-11-01

    Anodic polarization curves for a solution-treated or sensitized SUS 304 stainless steel and solution-treated Fe-Ni-Cr ternary alloys containing 10%Ni and 6 to 14%Cr have been measured in deaerated 0.5 mol/l Na/sub 2/SO/sub 4/ solutions of pH 2.0 to 5.9 at 298, 523 and 553 K. Corrosion potentials for U-bend SCC test specimens of sensitized SUS 304 stainless steel have also been monitored for a long time in the same solutions as those used for the polarization measurements except that they were aerated. It was found that the differences in the current densities in the passive state, i sub(pass), between the solution treated steel and the sensitized one and also between the ternary alloy with higher Cr content and the one with lower Cr content become large with increasing temperature and decreasing pH. This means that the difference in the values of i sub(pass) between grain bodies and Cr-depleted zones along grain boundaries of sensitized steel becomes larger and susceptibility to intergranular corrosion of the sensitized steel in the passivation region becomes higher with increasing temperature and decreasing pH. Since corrosion potentials for the U-bend SCC test specimens in air-satulated solutions lie in the passive region of anodic polarization curves for the sensitized steel in deaerated solutions, the intergranular stress-corrosion cracking of the sensitized steel in high temperature water with dissolved oxygen is considered to be caused by the preferential corrosion in the Cr-depleted zone.

  2. A novel link between Sus1 and the cytoplasmic mRNA decay machinery suggests a broad role in mRNA metabolism

    Directory of Open Access Journals (Sweden)

    Llopis Ana

    2010-03-01

    Full Text Available Abstract Background Gene expression is achieved by the coordinated action of multiple factors to ensure a perfect synchrony from chromatin epigenetic regulation through to mRNA export. Sus1 is a conserved mRNA export/transcription factor and is a key player in coupling transcription initiation, elongation and mRNA export. In the nucleus, Sus1 is associated to the transcriptional co-activator SAGA and to the NPC associated complex termed TREX2/THSC. Through these associations, Sus1 mediates the nuclear dynamics of different gene loci and facilitate the export of the new transcripts. Results In this study, we have investigated whether the yeast Sus1 protein is linked to factors involved in mRNA degradation pathways. We provide evidence for genetic interactions between SUS1 and genes coding for components of P-bodies such as PAT1, LSM1, LSM6 and DHH1. We demonstrate that SUS1 deletion is synthetic lethal with 5'→3' decay machinery components LSM1 and PAT1 and has a strong genetic interaction with LSM6 and DHH1. Interestingly, Sus1 overexpression led to an accumulation of Sus1 in cytoplasmic granules, which can co-localise with components of P-bodies and stress granules. In addition, we have identified novel physical interactions between Sus1 and factors associated to P-bodies/stress granules. Finally, absence of LSM1 and PAT1 slightly promotes the Sus1-TREX2 association. Conclusions In this study, we found genetic and biochemical association between Sus1 and components responsible for cytoplasmic mRNA metabolism. Moreover, Sus1 accumulates in discrete cytoplasmic granules, which partially co-localise with P-bodies and stress granules under specific conditions. These interactions suggest a role for Sus1 in gene expression during cytoplasmic mRNA metabolism in addition to its nuclear function.

    Full Text Available El propósito de este artículo es evidenciar, mediante el método etnográfico, las creencias sobre la obesidad de niños y niñas en edad escolar y las de sus progenitores, pertenecientes a una escuela urbana y pública de San José, Costa Rica. Los resultados apuntan hacia las creencias negativas de la niñez respecto a sus pares con obesidad y sus implicaciones psicosociales y afectivas. En relación con los progenitores se señalan las causas y estrategias de control, las implicaciones de la obesidad, referente a enfermedades físicas y emocionales; el papel del hogar y de la escuela en su prevención. Se concluye que los niños y las niñas creen que la obesidad no es una enfermedad, sino u na expresión fenotípica, a la cual le dan grado de relatividad o de escala y la consideran no deseable, resultado que concuerda con la de sus progenitores. Las niñas participantes con obesidad expresaron sus posiciones de defensa y molestia, en relación con experiencias burlescas. Al contrario de sus hijos e hijas, la mayoría de los progenitores sí cree que la obesidad es una enfermedad o un problema de salud o de estética. Además, estiman que esta se controla utilizando una dieta saludable y equilibrada, dando consejos sobre las consecuencias físicas y emocionales de la obesidad y ofreciendo modelos de personas saludables. Por lo tanto, los progenitores y el personal docente creen que la escuela poco puede hacer respecto a la alimentación saludable del alumnado, pues el hogar es el lugar que tiene un papel primordial.

    Full Text Available Bajo cualquier esquema de enseñanza-aprendizaje de la matemática, cuando al alumno se le señalan errores en su trabajo, puede, en general, adoptar tres tipos de actitud: una actitud negativa, bajo la cual el alumno considera que sus errores son sencillamente un síntoma de su fracaso; una actitud neutra o indiferente ante sus errores; o una actitud positiva, considerándolos como un medio para aprender y planteándose como reto el superarlos. Este artículo muestra una investigación que abordó el estudio de actitudes vinculadas al proceso de aprendizaje de la matemática. Su objetivo fue describir la actitud que el estudiante de ingeniería de la Uni- versidad del Zulia exhibe frente a sus errores cuando aprende matemática. La sus tentación teórica se baso en Brousseau (2001, Briñol et al. (2007 y los autores Pallí y Martínez (2004.

El instrumento fue validado mediante juicio de expertos y se determinó que era de alta confiabilidad, con un alpha de Cronbach de 0.9073. Se concluyó que los participantes, en su mayoría, mostraron una actitud moderadamente positiva hacia sus errores, que al no estar ubicada en el extremo positivo deseable refleja una actitud débil que no garantiza una conducta adecuada hacia los errores, pero que sin embargo es sus ceptible de ser mejorada hacia una actitud francamente positiva.

  15. Low-cycle fatigue properties of SUS304 stainless steel in high-temperature sodium

    International Nuclear Information System (INIS)

    Hirano, M.; Komine, R.; Kitao, K.; Nihei, I.; Yoshitoshi, A.

    Low-cycle fatigue tests in sodium and in air have been performed to investigate the influence of a high-temperature sodium environment on the strain-controlled fatigue behaviour for SUS304 stainless steel. The oxygen concentration in sodium was 2.4 ppm at the cold trap temperature of 145 deg. C. Tests in both environments were conducted at 450 deg. C, 550 deg. C and 650 deg. C at a constant strain rate of 1x10 -3 /sec with a fully-reversed triangular waveform and a zero mean strain. The fatigue life of SUS304 stainless steel in sodium at 450 deg. C, 550 deg. C and 650 deg. C was greater than those in air at the same temperature except at higher strain range (>0.8%) at 650 deg. C, and this difference had a tendency to increase as the total strain range decreases. At the higher total strain range at 650 deg. C, there was no marked difference between both environments. As the temperature increased, the fatigue life in sodium and in air decreased, and the Nsub(f sodium)/Nsub(f air) ratio also decreased. Microscopic examination of specimens tested in sodium and in air at 450 deg. C, 550 deg. C and 650 deg. C revealed no difference in the microstructure, but few surface cracks were observed on specimens tested in sodium than in those tested in air. Fractography of specimens tested in air at 450 deg. C, 550 deg. C and 650 deg. C revealed well-defined striations. But, in sodium, striations on specimens tested at 450 deg. C and 550 deg. C showed obscure configuration and it was difficult to find out, whereas, at 650 deg. C in sodium intergranular fracture was observed. The specimens tested in sodium had a longer fatigue life than those tested in air because the latter are subjected to considerable oxidation, while the former are free of such chemical action. Accordingly, it is concluded that crack initiation and propagation are more likely to occur in air than in sodium. (author)

    Full Text Available RESUMEN Los hongos-roya (Uredinales, Basidiomycetes representan uno de los grupos de microorganismos fitoparásitos más diversos y con mayor importancia económica mundial en la producción agrícola y forestal. Se caracterizan por ser patógenos obligados y por presentar una estrecha coevolución con sus hospedantes vegetales. Su taxonomía se ha basado fundamentalmente en el estudio de caracteres morfológicos, resultando en muchos casos en la formación de taxones polifiléticos. Sin embargo, en los últimos años se han tratado de incorporar herramientas moleculares que conduzcan a la generación de sistemas de clasificación basados en afinidades evolutivas. En esta revisión se ofrece una mirada general a las características de los uredinales, enfatizando en el surgimiento reciente de estudios filogenéticos que plantean la necesidad de establecer una profunda revisión de la taxonomía de este grupo. Finalmente se alerta sobre la necesidad de que en dichos estudios taxonómicos se incluya un alto número de especies de royas neotropicales, pues esta zona es reconocida no sólo por su alta diversidad de hongos-royas, sino también por las características únicas de sus ciclos de vida. Palabras clave: filogenia, hongos-roya, Puccinia, secuenciación, teliosporas. ABSTRACT Rust fungi (Uredinales, Basidiomycetes are one of the most diverse and economically important plant pathogens of crops world-wide. They are obligated parasites and have a close evolutionary relationship with their plant hosts. Taxonomy of this group has been based on morphological treats, resulting in generation of polyphyletic taxa. Recently, different studies have incorporated molecular techniques addressed to establishing evolutionary affinities between these fungi. This review presents a general view of the biological characteristics of rust fungi, with a detailed discussion on the phylogenetic studies regarding the group.

    Full Text Available The city of Buenos Aires was founded, for the second time 1580 essentially as an outpost of the Spanish Empire to be protected from Indian attacks and possible foreign incursion, basically Portuguese in origin. Thus, from the beginnings of the city's founding, African slaves were used for the defense of the city. They acted in the urban militias, and were outstanding in the defense and re-conquest of the city when the English attacked in 1806- 1807. Innumerable prizes and eulogies were followed by integration of segregated divisions with a white officer corps.After 1813, a series of decrees ordered owners to exchange slaves for use in the Wars of Independence. Thus, property owners were obliged to sell to the State a number of their slaves according to the work performed by the slaves. The slaves would enter the armies as free persons and would serve five years as 'front line" soldiers in order to obtain their freedom. This article studies the participation of the Afro-Argentines in the distinct 'fronts" of the armies of liberation. The paper also reflects on the opinions of the generals who commanded Afro-Argentine troops.//La ciudad de Buenos Aires fue fundada, por segunda vez, en 1580 esencialmente como un puesto de avanzada para que los españoles se protegieran de los indígenas y de una posible incursión extranjera de origen portugués.

Los esclavos actuaban en milicias urbanas y sus acciones fueron decisivas para la defensa y reconquista de Buenos Aires cuando los ingleses la atacaron en 1806-1807. Innumerables premios y elogios fueron seguidos por la integración de las divisiones separadas, con un cuerpo de oficiales blancos. Después de 1813, una serie de decretos ordenaba a los dueños entregar a sus esclavos para las guerras de Independencia .

    In eukaryotes, the nuclear export of mRNAs is essential for gene expression. However, little is known about the role of mRNA nuclear export in the important fungal pathogen, Candida albicans. In this study, we identified C. albicans Sus1, a nucleus-localized protein that is required for mRNA export. Interestingly, the sus1Δ/Δ displayed hyper-sensitivity to extracellular oxidative stress, enhanced ROS accumulation and severe oxidative stress-related cell death. More strikingly, although the mutant exhibited normal activation of the expression of oxidative stress response (OSR) genes, it had attenuated activity of ROS scavenging system, which may be attributed to the defect in OSR mRNA export in this mutant. In addition, the virulence of the sus1Δ/Δ was seriously attenuated. Taken together, our findings provide evidence that the mRNA export factor Sus1 plays an important role in oxidative stress tolerance and pathogenesis. Copyright © 2018 Elsevier Inc.

Dos cepas obtenidas de alimento de cabras produjeron 100 % de letalidad por ambas vías de inoculación y no mostraron diferencia significativa con la cepa testigo (P>0.05 respecto al porcentaje de invasión y a los parámetros de la cinética de crecimiento cuadrática observada en ambas líneas celulares. Si bien todas las cepas lograron invadir las células Caco-2, solamente algunas consiguieron invadir el bazo después de la inoculación por vía intragástrica. Las dos cepas provenientes de alimento de cabras fueron las más virulentas, representando un riesgo para la salud humana y animal, ya que pueden ser diseminadas en el hato y de este a otras explotaciones o a las instalaciones donde se elaboran alimentos.
