    Edge detection is necessary for image segmentation and pattern recognition. In this paper, an improved Canny edge detection approach is proposed due to the defect of traditional algorithm. A modified bilateral filter with a compensation function based on pixel intensity similarity judgment was used to smooth image instead of Gaussian filter, which could preserve edge feature and remove noise effectively. In order to solve the problems of sensitivity to the noise in gradient calculating, the algorithm used 4 directions gradient templates. Finally, Otsu algorithm adaptively obtain the dual-threshold. All of the algorithm simulated with OpenCV 2.4.0 library in the environments of vs2010, and through the experimental analysis, the improved algorithm has been proved to detect edge details more effectively and with more adaptability.

    Full Text Available biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual. Iris recognition is regarded as the most reliable and accurate biometric identification system available. Most commercial iris recognition systems use patented algorithms developed by Daugman, and these algorithms are able to produce perfect recognition rates. Especially it focuses on image segmentation and feature extraction for iris recognition process. The performance of iris recognition system highly depends on edge detection. The Canny Edge Detector is one of the most commonly used image processing tools, detecting edges in a very robust manner. For instance, even an effective feature extraction method would not be able to obtain useful information from an iris image that is not segmented properly. This paper presents a straightforward approach for segmenting the iris patterns. The used method determines an automated global threshold and the pupil center. Experiments are performed using iris images obtained from CASIA database (Institute of Automation, Chinese Academy of Sciences and Matlab application for its easy and efficient tools in image manipulation.

    2011-01-01

    Facial Expression Classification is an interesting research problem in recent years. There are a lot of methods to solve this problem. In this research, we propose a novel approach using Canny, Principal Component Analysis (PCA) and Artificial Neural Network. Firstly, in preprocessing phase, we use Canny for local region detection of facial images. Then each of local region's features will be presented based on Principal Component Analysis (PCA). Finally, using Artificial Neural Network (ANN)applies for Facial Expression Classification. We apply our proposal method (Canny_PCA_ANN) for recognition of six basic facial expressions on JAFFE database consisting 213 images posed by 10 Japanese female models. The experimental result shows the feasibility of our proposal method.

    Full Text Available The lumbar vertebrae are the largest segments of the movable part of the vertebral column, they are elected L1 to L5, starting at the top. The spinal column, more commonly called the backbone, is made up primarily of vertebrae discs, and the spinal cord. Acting as a communication conduit for the brain, signals are transmitted and received through the spinal cord. It is otherwise known as vertebralcolumn consists of 24 separate bony vertebrae together with 5 fused vertebrae, it is the unique interaction between the solid and fluid components that provides the disc strength and flexibility required to bear loading of the lumbar spine. In this work the Segmentation of Spine Image using Median Filter and Canny Edge Detection Algorithm between lumbar spine CT scan spine disc image. The result shows thatthe canny edge detection algorithm produced better result when compared other edge detection algorithm. Finding the correct boundary in a noisy image of spine disc is still a difficult one. To find outabsolute edges from noisy images, the comparative result can be verified and validated with the standard medical values. The result shows that the canny edge detection algorithm performs well and produced a solution very nearer to the optimal solution. This method is vigorous for all kinds of noisy images.

    2011-01-01

    In the last few years, a variety of multicore architectures have been used to parallelize image processing applications. In this paper, we focus on assessing the parallel speed-ups of different Canny edge detection parallelization strategies on the Tile64, a tiled multicore architecture developed by the Tilera Corporation. Included in these strategies are different ways Canny edge detection can be parallelized, as well as differences in data management. The two parallelization strategies examined were loop-level parallelism and domain decomposition. Loop-level parallelism is achieved through the use of OpenMP,1 and it is capable of parallelization across the range of values over which a loop iterates. Domain decomposition is the process of breaking down an image into subimages, where each subimage is processed independently, in parallel. The results of the two strategies show that for the same number of threads, programmer implemented, domain decomposition exhibits higher speed-ups than the compiler managed, loop-level parallelism implemented with OpenMP.

    During domestication, the dog( Canis familiaris), have become skilful in understanding human communication and also in communicating with humans. The wolf ( Canis lupus), is not as skilled with this interspecific communication. When dogs are faced with an unsolvable problem, they seek help from human by e.g. gazing at them. This behaviour has been studied and both age and breed group differences have been showed. In this study, we presented dogs with a task that consisted of a solvable and un...

  14. Efficient edge-guided full-waveform inversion by Canny edge detection and bilateral filtering algorithms

    Xiang, Shiming; Zhang, Haijiang

    2016-11-01

    It is known full-waveform inversion (FWI) is generally ill-conditioned and various strategies including pre-conditioning and regularizing the inversion system have been proposed to obtain a reliable estimation of the velocity model. Here, we propose a new edge-guided strategy for FWI in frequency domain to efficiently and reliably estimate velocity models with structures of the size similar to the seismic wavelength. The edges of the velocity model at the current iteration are first detected by the Canny edge detection algorithm that is widely used in image processing. Then, the detected edges are used for guiding the calculation of FWI gradient as well as enforcing edge-preserving total variation (TV) regularization for next iteration of FWI. Bilateral filtering is further applied to remove noise but keep edges of the FWI gradient. The proposed edge-guided FWI in the frequency domain with edge-guided TV regularization and bilateral filtering is designed to preserve model edges that are recovered from previous iterations as well as from lower frequency waveforms when FWI is conducted from lower to higher frequencies. The new FWI method is validated using the complex Marmousi model that contains several steeply dipping fault zones and hundreds of horizons. Compared to FWI without edge guidance, our proposed edge-guided FWI recovers velocity model anomalies and edges much better. Unlike previous image-guided FWI or edge-guided TV regularization strategies, our method does not require migrating seismic data, thus is more efficient for real applications.

    Full Text Available Canine Atopic Dermatitis is a skin disease of genetic origin. The affected dog becomes sensible to antigens presents in the environment, developing a severe alergic, pruriginous reaction, which intervenes in the quality of life of the patient. Because of the genetic character, that is an illness that in most of the times has no cure, just control. The treatment in general is lifetime. Thus, some used drugs, for example the corticosteroides, might cause collateral effects when used for a long time, and might decrease the lifetime of the animals. By this way, the owner of the dog with atopia, must know about the complications of the disease, and occasional return of the clinical signs during the period of treatment. Therefore, this article has an objective of a review about Canine Atopic Dermatitis that is an increasing problem in the small animal practice.A Dermatite Atópica Canina é uma dermatopatia de origem genética. Os cães acometidos tornam-se sensíveis aos antígenos presentes no meio ambiente, desenvolvendo grave reação alérgica, pruriginosa, que interferem na qualidade de vida do paciente. Devido ao seu caráter genético, esta é uma doença que na maioria das vezes não tem cura, apenas controle. O tratamento em geral é vitalício. Assim sendo, algumas drogas utilizadas, a exemplo dos corticosteróides, podem causar efeitos colaterais que em longo prazo, são capazes de diminuir o período de vida do animal. Desta maneira, o proprietário do cão portador de atopia, precisa ser esclarecido em relação às complicações e provável recidiva dos sinais clínicos, durante o período de tratamento. Portanto, presente artigo tem como objetivo uma revisão sobre Dermatite Atópica Canina, que está se tornando um problema crescente na clínica de pequenos animais.

    2001-06-01

    On the basis of a study by D. J. Povinelli, D. T. Bierschwale, and C. G. Cech (1999), the performance of family dogs (Canis familiaris) was examined in a 2-way food choice task in which 4 types of directional cues were given by the experimenter: pointing and gazing, head-nodding ("at target"), head turning above the correct container ("above target"), and glancing only ("eyes only"). The results showed that the performance of the dogs resembled more closely that of the children in D. J. Povinelli et al.'s study, in contrast to the chimpanzees' performance in the same study. It seems that dogs, like children, interpret the test situation as being a form of communication. The hypothesis is that this similarity is attributable to the social experience and acquired social routines in dogs because they spend more time in close contact with humans than apes do, and as a result dogs are probably more experienced in the recognition of human gestures.

    Full Text Available Fourteen females belonging to five groups were selected for the study of mating system in free-ranging domestic dogs (Canis familiaris All the matings occurred between August and December with a peak in late monsoon months (September to November. Both males and females differed in their degree of attractiveness to the opposite sex. The duration of courting association increased with the number of courting males in an association. The females exhibited selectivity by readily permitting some males to mate and avoiding, or even attacking others, if they attempted to mount. Frequency of mounting in courting association increased with the number of males present. There was a positive correlation between the duration of courting association and the frequency of mounting. The young adult males were more likely to copulate successfully than the old adult males. There was a negative correlation between the number of males present in an association and the number of successful copulations. In this study, six types of mating (monogamy, polygyny, promiscuity, polyandry, opportunity and rape were recorded. Mean (±S.E. duration of copulatory ties was 25.65 (±1.43 min. Several natural factors influencing the duration of copulatory ties were identified.

    All dogroses (Rosa sect. Caninae) are characterized by the peculiar canina meiosis in which genetic material is unevenly distributed between female and male gametes. The pan-canina rDNA family (termed beta) appears to be conserved in all dogroses analyzed so far. Here, we have studied rDNAs in experimental hybrids obtained from open pollination of F1 plants derived from 2 independent intersectional crosses between the pentaploid dogrose species (2n = 5x = 35) Rosa rubiginosa as female parent (producing 4x egg cells due to the unique asymmetrical canina meiosis) and the tetraploid (2n = 4x = 28) garden rose R. hybrida 'André Brichet' as male parent (producing 2x pollen after normal meiosis). We analyzed the structure of rDNA units by molecular methods [CAPS and extensive sequencing of internal transcribed spacers (ITS)] and determined the number of loci on chromosomes by FISH. FISH showed that R. rubiginosa and 'André Brichet' harbored 5 and 4 highly heteromorphic rDNA loci, respectively. In the second generation of hybrid lines, we observed a reduced number of loci (4 and 5 instead of the expected 6). In R. rubiginosa and 'André Brichet', 2-3 major ITS types were found which is consistent with a weak homogenization pressure maintaining high diversity of ITS types in this genus. In contrast to expectation (the null hypothesis of Mendelian inheritance of ITS families), we observed reduced ITS diversity in some individuals of the second generation which might derive from self-fertilization or from a backcross to R. rubiginosa. In these individuals, the pan-canina beta family appeared to be markedly enriched, while the paternal families were lost or diminished in copies. Although the mechanism of biased meiotic transmission of certain rDNA types is currently unknown, we speculate that the bivalent-forming chromosomes carrying the beta rDNA family exhibit extraordinary pairing efficiency and/or are subjected to strong selection in Caninae polyploids.

    Full Text Available As part of ongoing project on screening plants used in Iranian folk medicine to treatment of diabetes, α-glucosidase inhibition activities of Rosa canina extracts have been tested. The acetone extract of the plant exhibited significant inhibition with IC 50 value of 0.3 µg/ml. The enzyme based assay guided fractionation of the acetone extract led to the isolation of daucosterol (1 and D-glucono-1,4-lactone (2, as highly active α-glucosidase inhibitors. Their structures were determined by 1H- and 13C-NMR spectroscopic evidences. The IC 50 values of daucosterol and D-glucono-1,4-lactone on yeast α-glucosidase were 13.3 and 6.5 µM, respectively, while IC 50 of acarbose was 16.1 µM, as a positive control. The Lineweaver-Burk plots analysis elucidated that both of the compounds inhibited the enzyme competitively. The study suggests that isolated compounds can be good candidates as α-glucosidase inhibitors and provide strong rationale for more in vivo studies.

    Health beneficial properties of Rosa canina species are mainly attributed to rose hips, while the leaves are usually discarded as waste. In the present study we investigated chemical constituents as well as antimicrobial and antibiofilm potential of R. canina methanolic leaf extract. Chemical analysis showed that dominant phenolic compounds are quercetin and isorhamnetin derivatives (isoquercetin and isorhamnetin-3-O-rutinoside). Among the tested bacteria, Pseudomonas aeruginosa and Salmonella typhimurium were the most susceptible to the activity of R. canina leaf extract with MIC and MBC values both 0.009 mg mL(-1). For most of the bacterial strains investigated the extract showed significantly higher activity compared to the used standard compounds streptomycin and ampicillin. Also the tested extract powerfully inhibited in vitro biofilm growth in Pseudomonas aeruginosa, Staphylococcus aureus, Leishmania monocytogenes and Escherichia coli at sub MIC-levels. With concentrations equal to 1/4 and 1/8 of MIC values biofilm growth of P. aeruginosa and E. coli was inhibited by 90%. The obtained results are significant for a wider and efficient use of R. canina leaves. PMID:26399901

    In order to realise the quick image segmentation in the DSP platform,the Canny detector theory is analyzed in detail. The arithmetic transplant was implemented in combition with TI DSP TMS320C6678 processor properties. Aiming at data interaction with the images in external memory,the past mode that the images were accessed according to gray values one by one was improved. The vectorized packed data was designed for dealing with Gaussian filtering to improve the parallel operation, and the accessing method of wide memory in the process of gradient compution and the threshold value calculation was adopted to improve the read-write efficiency of external memory. The result indicates that the optimization method designed in this paper can improve the velocity of Canny operator under the condition of not changing the segmentation result,and can provide a reference for the engineers to carry out arithmetic transplant and optimization on the DSP platform.%为了在DSP平台实现细胞图像快速分割,详细分析Canny算子原理,结合TI DSP TMS320C6678处理器特性,实现了算法移植。针对与外部存储器图像数据交互,改变以往对图像逐灰度值进行访问的方式,设计了矢量化数据打包方法处理高斯滤波来提高并行运算。且在梯度计算、阈值计算过程中,采用宽存储器访问方法提高读写外部存储器效率。结果表明设计的优化方法在不改变分割效果前提下改善了算子速度,可为工程人员在DSP平台进行算法移植与优化提供借鉴。

    The in vitro antiproliferative and antioxidant effects of different fractions of Rosa canina hips on human colon cancer cell lines (Caco-2) was studied. The compounds tested were total extract (fraction 1), vitamin C (fraction 2), neutral polyphenols (fraction 3) and acidic polyphenols (fraction 4). All the extracts showed high cytotoxicity after 72 h, both low and high concentrations. The flow cytometric analysis revealed that all the fractions produce disturbances in the cell cycle resulting in a concomitant cell death by an apoptotic pathway. Changes in the redox status of Caco-2 cells in response to Rosa canina hips were determined. Cells were exposed to hydrogen peroxide in presence of plant fractions and the production of Reactive Oxygen Species (ROS) was significantly decreased. Therefore, our data demonstrate that rosehip extracts are a powerful antioxidant that produces an antiproliferative effect in Caco-2 cells. Therefore, these results predict a promising future for Rosa canina as a therapeutic agent. Thus, this natural plant could be an effective component of functional foods addressed towards colorectal carcinoma. PMID:27467555

    We studied the primary brood sex ratio of an old-growth forest passerine, the Eurasian treecreeper (Certhia familiaris), along a gradient of forest fragmentation. We found evidence that male nestlings were more costly to produce, since they suffered twofold higher nestling mortality and were larger in body size than females. Furthermore, the proportion of males in the brood was positively associated with the provisioning rate and the amount of food delivered to the nestlings. During the first...

    Recent research suggests that some human-like social skills evolved in dogs (Canis familiaris) during domestication as an incidental by-product of selection for “tame” forms of behavior. It is still possible, however, that the social skills of certain dog breeds came under direct selection that led to further increases in social problem solving ability. To test this hypothesis, different breeds of domestic dogs were compared for their ability to use various human communicative behaviors to fi...

    2010-01-01

    Full Text Available The volatile oils of R. canina flowers were isolated by hydrodistillation (HD and traditional dry distillation (DD and analyzed by HRGC-FID and GC-MS. Compared to HD, DD at 50°C leads to the isolation of high quality oil which contains the highest content of oxygenated compounds (83%. The main components are the 2-phenethyl alcohol and eugenol. The percentage of the 2-phenethyl alcohol, a highly desirable component in rose oil, was significantly higher (58.4% in DD extract when compared to that of HD one (13.6%. As temperature increased (100°C during DD, the oil quality decreased. The most significant changes were observed in 2-phenethyl alcohol percentage (4.5%. Moreover, an increase of alkanes/alkenes and the production of furan derivatives were observed. So, DD at moderate temperature (50°C seemed more suitable to improve the volatile oil quality and hence, to make more value of R. canina.

    This study evaluated the performance of the EIE-leishmaniose-visceral-canina-Bio-Manguinhos (EIE-LVC) kit and to compare it with that of the IFI-leishmaniose-visceral-canina-Bio-Manguinhos (IFI-LVC) kit. Four groups of dogs were studied: group 1 (G1), dogs with clinical signs indicative of CVL and testing positive for the parasite (n = 25); group 2 (G2), dogs with only a presumed diagnosis of CVL (n = 62); group 3 (G3), dogs that had never lived in an area where CVL is endemic and never received a blood transfusion (n = 16); group 4 (G4), dogs carrying other parasites: such as babesiosis (n = 4), ehrlichiosis (n = 6) and demodicosis (n = 1). G1 and G3 were used for the calculation of sensitivity and specificity, respectively. The EIE-LVC showed a sensitivity of 72% (IC 95%: 50.4-87.1%) and a specificity of 87.5% (IC 95%: 60.4-97.8%). The value of the kappa index was 0.975 (CI 95%: 0.926-1.024), which represents an excellent fit. For IFI-LVC, the sensitivity was 68.0% (CI 95%: 46.4-84.3%) and the specificity 87.5% (CI 95%: 60.4-97.8%). When the tests were conducted in parallel, sensitivity was 92.0% (CI 95%: 72.5-98.6%) and specificity 75.0% (CI 95%: 47.4-91.7%). However, when conducted consecutively, the tests showed a sensitivity of 48.0% (CI 95%: 28.3-68.2%) and a specificity of 100.0% (CI 95%: 75.9-99.4%). The analysis of clinically suspected dogs using IFI-LVC and EIE-LVC kits in parallel, revealed that 26/62 animals were positive. Cross-reaction was observed in a dog with demodicosis. These results lead to the following conclusions: (1) the performance of the EIE-LVC kit is not statistically different from the IFI-LVC and (2) the kits must be used in parallel if higher sensitivity is required, reducing the number of false-negative results.

    As part of a programme of comparative measurements of Pd (diffusional water permeability) the RBCs (red blood cells) from dingo (Canis familiaris dingo) and greyhound dog (Canis familiaris) were studied. The morphologies of the dingo and greyhound RBCs [examined by light and SEM (scanning electron microscopy)] were found to be very similar, with regard to aspect ratio and size; the mean diameters were estimated to be the same (approximately 7.2 microm) for both dingo and greyhound RBCs. The water diffusional permeability was monitored by using an Mn2+-doping 1H NMR technique at 400 MHz. The Pd (cm/s) values of dingo and greyhound RBCs were similar: 6.5 x 10(-3) at 25 degrees C, 7.5 x 10(-3) at 30 degrees C, 10 x 10(-3) at 37 degrees C and 11.5 x 10(-3) at 42 degrees C. The inhibitory effect of a mercury-containing SH (sulfhydryl)-modifying reagent PCMBS (p-chloromercuribenzene sulfonate) was investigated. The maximal inhibition of dingo and greyhound RBCs was reached in 15-30 min at 37 degrees C with 2 mmol/l PCMBS. The values of maximal inhibition were in the range 72-74% when measured at 25 degrees C and 30 degrees C, and approximately 66% at 37 degrees C. The lowest value of Pd (corresponding to the basal permeability to water) was approximately 2-3 x 10(-3) cm/s in the temperature range 25-37 degrees C. The Ea,d (activation energy of water diffusion) was 25 kJ/mol for dingo RBC and 23 kJ/mol for greyhound RBCs. After incubation with PCMBS, the values of Ea,d increased, reaching 46-48 kJ/mol in the condition of maximal inhibition of water exchange. The electrophoretograms of membrane polypeptides of the dingo and greyhound RBCs were compared and seen to be very similar. We postulate that the RBC parameters reported in the present study are characteristic of all canine species and, in particular in the two cases presented here, these parameters have not been changed by the peculiar Australian habitat over the millennia (as in the case of the dingo) or over

    Full Text Available Domesticated dogs (Canis familiaris are an important human companion around the world and have long been a focus of archaeological research. Osteometric analysis of six dogs from a Late Holocene Chumash village on Santa Rosa Island, California indicates that adults, juvenile/young adults, and a puppy were present. Similar to dogs on other Channel Islands, these dogs fall into the large Indian dog category, standing some 43-54 cm tall, with mesaticephalic or mild brachycephalic facial characteristics. No cutmarks were found on the bones, but one of the mandibles was burned. The CA-SRI-2 dogs appear to have eaten high trophic marine foods similar to what humans consumed, documenting the close bond between dogs and humans on the Channel Islands and broader North American Pacific Coast.

    We investigated whether the consumption of a morning meal (breakfast) by dogs (Canis familiaris) would affect search accuracy on a working memory task following the exertion of self-control. Dogs were tested either 30 or 90 min after consuming half of their daily resting energy requirements (RER). During testing dogs were initially required to sit still for 10 min before searching for hidden food in a visible displacement task. We found that 30 min following the consumption of breakfast, and 10 min after the behavioral inhibition task, dogs searched more accurately than they did in a fasted state. Similar differences were not observed when dogs were tested 90 min after meal consumption. This pattern of behavior suggests that breakfast enhanced search accuracy following a behavioral inhibition task by providing energy for cognitive processes, and that search accuracy decreased as a function of energy depletion.

    Domestic dogs (Canis familiaris) are notably skillful in following cues from people (e.g., pointing gestures). However, not much is known about the processing of information available during such tasks. We here focus on one of the earliest of such processes, namely attention. The goal of the present work was to describe variations in dogs' attention towards diverse targets while they solve an object choice task with human pointing. The direction of subjects' gaze was measured in the period comprising one second before and two seconds after the experimenter called the dog and simultaneously performed a static distal pointing gesture towards the correct bowl. We did two consecutive training phases: acquisition and extinction. Dogs spent more time watching the pointer than the pointing gesture itself and the correct than the incorrect bowl. Indeed, the time spent watching the correct bowl was the best predictor of correct choices across phases. We discuss the relevance of these findings for the process of local enhancement.

    A previously published systematic review and a metaanalysis have concluded that the consumption of standardized rose hip powder (Rosa canina L.) can reduce pain in osteoarthritis patients. Synovial inflammation has been suggested to play an important role in the pathogenesis of osteoarthritis...... and mainly to involve infiltration of the synovial membrane by macrophages. Therefore, the immunomodulatory effect of standardized rose hip powder of Rosa canina L. was investigated and active principles isolated using the Mono Mac 6 cell line as a model for human macrophages. Treatment of Mono Mac 6 cells...... with the residue of a crude dichloromethane extract of rose hip powder significantly and concentration dependently inhibited the lipopolysaccharide induced interleukin-6 release. Through bioassay-guided fractionation the immunomodulatory effect of the dichloromethane extract was correlated to a mixture of three...

    Full Text Available Conoscere gli animali familiari è la settima uscita della collana diretta da Paolo Polidori "produzioni animali e sicurezza alimentare" sulla ricerca nell'ambito della nutrizione e alimentazione animale, zootecnia, ispezione degli alimenti di origine animale, clinica medica e parassitologia veterinaria con risvolti di natura tecnica, scientifica e pratica. Il volume, redatto da medici veterinari in servizio presso differenti Aziende Sanitarie italiane, è un sintetico manuale su domesticazione, cura sanitaria, etnografia e addestramento del proprio cane (o gatto. Gli autori partono dall'assunto che i proprietari scelgono il cane per lo più sulla base del gusto visivo o sulla consuetudine tramandata in famiglia, senza un'esaustiva conoscenza degli aspetti riguardanti l'origine dell'animale, la sua attitudine prevalente, le sue patologie ricorrenti e le eventuali predisposizioni genetiche nei confronti di una determinata patologia. Puntano l'accento sin dalle prime battute sul cambiamento culturale che ha modificato anche il rapporto uomo-animale sotto l'aspetto sociale, effettuale e giuridico. L'animale da semplice "res" si è da tempo affermato come un essere diverso ma senziente, quindi destinatario di tutele, con diritti contemplati dalle carte costituzionali di diversi Paesi. Per questo motivo chi detiene un animale domestico deve prepararsi ad un impegno non riducibile al possesso di un oggetto, al punto di risponderne penalmente per eventuali sofferenze fisiche o psicologiche, per l'abbandono (anche solo temporaneo o per l'incuria. Conoscere gli animali familiari fornisce nozioni scientifiche e sanitarie alla portata di tutti, utili soprattutto nelle occasioni in cui i proprietari dovranno recarsi dal veterinario o affrontare visite legate alla profilassi e alle vaccinazioni di routine.

    Nowadays , Graphic printing becomes more and more important for the blind. As a new Braille printing tool, New Braille Printer(NBP) has overcome many shortcomings of traditional Braille printer. But, till now, the NBP could't has the functin of graphic printing. In order to improve the new Braille printer, a blind graphic printing method has been proposed. Considering the characteristics of the printing image, it utilized loop iteration method to select Canny operators with different thresholds, and then, took edge detection on the printing image to gained a series of edge images with the selected Canny operators. The accurate shape information of printing image was translated into NBP's control information, then the control information was used to control the NBP to print the blind graphic which gained from iterative calculation of this edge images. This method has been test on NBP, and blind graphics were printed on A4 paper clearly and completely.%随着信息技术的发展,盲用图形对于盲人而言,变得越来越重要。新型盲文打印机作为盲文印刷的新型工具,它克服了传统盲文印刷的许多缺点,但是,目前该盲文打印机还不具备打印盲文图形的功能,为了完善新型盲文打印机,本文针对待打印的盲文图像的特点,采用循环迭代的方式,选择不同阈值的Canny算子对待打印图像进行边缘提取,并对所得到的一系列的边缘图像进行迭代计算,从而实现了待打印图像边缘特征的精确提取。待打印图像的边缘信息最终被转化为新型盲文打印机的控制信息控制新型盲文打印机完成打印,生成盲用图形,从而实现了新型盲文打印机图形打印功能。目前,该方法已经在新型盲文打印机试验,成功的实现了待打印图像在A4纸张上的清晰完整的打印。

  18. Evolution of sociality, diet, and craniodental anatomy in the subfamly caninae

    International Nuclear Information System (INIS)

    Social carnivores affect population parameters, ecology, behavior and speciation and extinction rates of their prey and other sympatric carnivores. Therefore, social carnivores may have influenced the evolution of the structure and organization of ancestral and modern mammal communities. Thus, it is important to identify what extinct carnivore species may have been social and to determine when, where and under which environmental contexts they evolved. The first step is to establish if there is an association between morphological traits, susceptible of being preserved in the fossil record, and differences in the degree of sociality of present day carnivores. The aim of this research was to establish if there is an association between variation in shape and variables related to mechanical properties of the skulls, and differences in sociality level, diet and sex in modern canids. The sample included 972 specimens of 33 canid species. We analyzed the shape of the lateral side of the cranium, zygomatic arch, dentary bone and mandibular corpus, as well as 20 variables related to mechanical properties of the skull. Results suggest that hypercarnivorous social canids have shapes and mechanical properties that are different from other modern canids. We found that morphological variation is not affected by sex. Results may be used to identify extinct caninae species that were social and hypercarnivorous. Results also suggest that the evolution of sociality is dependent on phylogenetic relationships and ecological context, particularly the abundance of large prey and the presence of sympatric carnivores.

    Although many studies have investigated domestic dogs' (Canis familiaris) use of human communicative cues, little is known about their use of humans' emotional expressions. We conducted a study following the general paradigm of Repacholi in Dev Psychol 34:1017-1025, (1998) and tested four breeds of dogs in the laboratory and another breed in the open air. In our study, a human reacted emotionally (happy, neutral or disgust) to the hidden contents of two boxes, after which the dog was then allowed to choose one of the boxes. Dogs tested in the laboratory distinguished between the most distinct of the expressed emotions (Happy-Disgust condition) by choosing appropriately, but performed at chance level when the two emotions were less distinct (Happy-Neutral condition). The breed tested in the open air passed both conditions, but this breed's differing testing setup might have been responsible for their success. Although without meaningful emotional expressions, when given a choice, these subjects chose randomly, their performance did not differ from that in the experimental conditions. Based on the findings revealed in the laboratory, we suggest that some domestic dogs recognize both the directedness and the valence of some human emotional expressions. PMID:22960805

    The aim of this study was to compare phenolic profile, vitamin C content, antioxidant, anti-inflammatory and cytotoxic activity of rose hips and the preserves (purée and jam) of two Rosa species: renowned Rosa canina L. and unexplored Rosa arvensis Huds. The liquid chromatography-tandem mass spectrometry analysis of 45 phenolics resulted in quantification of 14 compounds, with quercitrin, gallic and protocatechuic acids as the most dominant. High antioxidant potential of R. canina and a moderate activity of R. arvensis extracts were determined through several assays. Purée of both species and methanol extract of air-dried R. canina hips showed some anti-inflammatory (cyclooxygenase-1 and 12-lipooxygense inhibition potency) activity. Purée of R. canina exerted cytotoxic activity only against the HeLa cell line among several others (HeLa, MCF7, HT-29 and MRC-5). The presented results support traditional use of rose hips and their fruit preserves as food with health and nutritional benefits. PMID:26304428

    Full Text Available Naturally occurring canine osteoarthritis represents a welfare issue for affected dogs (Canis familiaris, but is also considered very similar to human osteoarthritis and has therefore been proposed as a model of disease in humans. Central sensitisation is recognized in human osteoarthritis sufferers but identification in dogs is challenging. Electromyographic measurement of responses to nociceptive stimulation represents a potential means of investigating alterations in central nociceptive processing, and has been evaluated in conscious experimental dogs, but is likely to be aversive. Development of a suitable anaesthetic protocol in experimental dogs, which facilitated electrophysiological nociceptive withdrawal reflex assessment, may increase the acceptability of using the technique in owned dogs with naturally occurring osteoarthritis. Seven purpose bred male hound dogs underwent electromyographic recording sessions in each of three states: acepromazine sedation, alfaxalone sedation, and alfaxalone anaesthesia. Electromyographic responses to escalating mechanical and electrical, and repeated electrical, stimuli were recorded. Subsequently the integral of both early and late rectified responses was calculated. Natural logarithms of the integral values were analysed within and between the three states using multi level modeling. Alfaxalone increased nociceptive thresholds and decreased the magnitude of recorded responses, but characteristics of increasing responses with increasing stimulus magnitude were preserved. Behavioural signs of anxiety were noted in two out of seven dogs during recordings in the acepromazine sedated state. There were few significant differences in response magnitude or nociceptive threshold between the two alfaxalone states.

    Recent studies have shown that the neuropeptide oxytocin is involved in the regulation of several complex human social behaviours. There is, however, little research on the effect of oxytocin on basic mechanisms underlying human sociality, such as the perception of biological motion. In the present study, we investigated the effect of oxytocin on biological motion perception in dogs (Canis familiaris), a species adapted to the human social environment and thus widely used to model many aspects of human social behaviour. In a within-subjects design, dogs (N = 39), after having received either oxytocin or placebo treatment, were presented with 2D projection of a moving point-light human figure and the inverted and scrambled version of the same movie. Heart rate (HR) and heart rate variability (HRV) were measured as physiological responses, and behavioural response was evaluated by observing dogs' looking time. Subjects were also rated on the personality traits of Neuroticism and Agreeableness by their owners. As expected, placebo-pretreated (control) dogs showed a spontaneous preference for the biological motion pattern; however, there was no such preference after oxytocin pretreatment. Furthermore, following the oxytocin pretreatment female subjects looked more at the moving point-light figure than males. The individual variations along the dimensions of Agreeableness and Neuroticism also modulated dogs' behaviour. Furthermore, HR and HRV measures were affected by oxytocin treatment and in turn played a role in subjects' looking behaviour. We discuss how these findings contribute to our understanding of the neurohormonal regulatory mechanisms of human (and non-human) social skills. PMID:26742930

  9. Effect of training and familiarity on responsiveness to human cues in domestic dogs (Canis familiaris).

    2014-05-01

    Domestic dogs (Canis familiaris) seem to possess an evolved competency to follow human-given cues, often out-performing their wild progenitor the wolf (Canis lupus) on cue-following tasks. However, domestication may not be solely responsible for the socio-cognitive skills of dogs, with ontogenetic experience also playing a role. This research evaluated the effects of intensive training on cue-following behaviour using an unreinforced object-choice paradigm. The responses of dogs that were trained to competitive levels were compared to those of pet dogs with only basic training, and dogs living in an animal shelter that demonstrated no or only rudimentary following of basic commands. Using a cue-following task where three types of cues were presented by familiar and unfamiliar human partners, the number of cues followed by each training group were recorded. All dogs found cues where gesture was combined with a congruent head and eye movement easier to follow than either gesture or eye gaze alone. Whether the cue-giver was familiar or not had a significant effect on number of cues followed in homed dogs, and the performance of shelter dogs was comparable to the other groups when faced with an unfamiliar cue-giver. Contrary to predictions, level of training did not improve performance on the cue-following task. This work does provide support for the presence of an evolved adaptation to exploit social cues provided by humans that can be augmented by familiarity with the cue giver. However, additional joint activity as experienced in an intensive training regime does not seem to increase accuracy in following human-given cues.

Se tomaron muestras sanguíneas en 10 machos y 44 hembras que fueron procesadas bajo la técnica de inmunocromatografía para Brucella canis. No hubo diferencia estadística entre albergues en los parámetros ‘sexo’ y ‘raza’ de cada grupo de estudio y tampoco se encontró evidencia serológica de la presencia de brucelosis canina en el grupo de animales muestreados. Los resultados indican que, aunque los animales permanecieron en calidad de abandono durante un período de su vida, su condición feral no era permanente debido a que en el momento del estudio se encontraban en albergues. Las políticas intensivas de recolección se orientan más a la atención de mascotas abandonadas que a aquellos animales ferales (los cuales, con mayor frecuencia, pueden ser portadores de la enfermedad.

Todavia, a trasmissão vertical e venérea da LVC está presente. Os principais sinais clínicos observados nos animais acometidos pela LVC são linfoadenomegalia, dermatopatias, hepatoesplenomegalia, onicogrifose e oftalmopatias, contudo quadros atípicos podem ser observados, inclusive com o envolvimento do sistema genital. Dessa forma, o objetivo deste artigo é realizar revisão sobre as principais patologias genitais em cães machos e fêmeas com leishmaniose visceral (LV.The canine visceral leishmaniasis (CanL is a chronic parasitic disease caused by protozoa belonging to the genus Leishmania. In Brazil, the transmission occurs mainly by the action of blood-sucking insects belonging to the subfamily Phlebotominae, particularly the Lutzomyia longipalpis species. However, the venereal and vertical transmission of the CanL is present. The main clinical signs observed in animals affected by the CanL are lymphadenopathy, skin diseases, hepatosplenomegaly, onychogryphosis and ophthalmopathy, however atypical manifestations can be observed, including the involvement of the genital system. Thus, the aim of this paper is to review on the major pathologies in genital male and female dogs with visceral leishmaniasis (VL.

    Full Text Available La arterioesclerosis es el endurecimiento de las arterias debido a cambios en las estructuras histológicas de la pared vascular, como hipertrofia muscular, tejido conectivo, depósito de calcio, lípidos, etc. La ateroesclerosis se caracteriza por la formación de placas fibrosas en la íntima, que a menudo tiene un núcleo central rico en lípidos; esta patología es el tipo más común de arterioesclerosis en la especie humana y, por lo tanto, de gran importancia para su estudio. Algunos autores reportan que la arterioesclerosis es común, pero de poca importancia en animales domésticos; además encasillan al perro (Canis lupus familiaris como aterorresistente. Sin embargo, en la actualidad son varios los reportes de lesiones vasculares similares a las observadas en humanos, que están relacionadas con la estrecha convivencia en su papel de mascota. Por tanto, la presente investigación se enfoca en la búsqueda y descripción de lesiones histopatológicas concernientes a arterioesclerosis en perros, mediante un estudio retrospectivo de la casuística del Laboratorio de Patología Veterinaria de la Universidad Nacional de Colombia. Después de revisar los informes de necropsia e histopatología, se seleccionaron 52 casos de perros que reportaban uno o varios factores predisponentes para el desarrollo de arterioesclerosis; las láminas histopatológicas fueron inicialmente evaluadas con la tinción de hematoxilina y eosina y se capturaron fotomicrografías de utilidad para futuras investigaciones. En 23 de los 52 casos seleccionados se observaron diferentes características de lesiones relacionadas con esta entidad, como vacuolas translúcidas, paredes de aspecto hialino, proliferación de tejido muscular o conectivo y deposiciones de mineral y pigmentos. Adicionalmente, en algunos casos se utilizó la coloración tricrómica de Masson para confirmar la presencia de tejido conectivo y muscular. Por último, se plantearon hipótesis sobre la

Para cada órgão foram atribuídos graus crescentes (de leve a acentuada de intensidade de imunomarcação. O antígeno de CAV-1 estava presente na maioria dos órgãos examinados, principalmente em células endoteliais. Relacionando o tempo de evolução clínica da HIC com a intensidade da imunomarcação, o maior número de casos com evolução clínica hiperaguda ou aguda coincidiu com a maior intensidade de marcação do antígeno viral. A IHQ demonstrou ser um teste adequado para a detecção do antígeno de CAV-1 e pode ser usado para o estudo da patogênese da doença.Tissues from 27 dogs died from infectious canine hepatitis (ICH were evaluated by immunohistochemestry (IHC for detection of canine adenovirus type 1 (CAV-1 antigen using a monoclonal antibody. Evaluated tissues included liver, kidney, spleen, lymph nodes, tonsils, lungs, small intestine, brain, and spinal cord. For each organ increasing degrees (from mild to marked of intensity of immune staining were ascribed. CAV-1 was detected in most of the evaluated organs, mainly in the endothelial cells. Considering the clinical course of ICH and the intensity of IHC staining, cases with acute and peracute courses had more marked staining. IHC proved to be a reliable test for CAV-1 antigen detection and can be used for pathogenesis studies on ICH either in the spontaneous and experimental disease.

    Thidiazuron (N-phenyl-N′-1,2,3-thiadiazol-5-ylurea; TDZ) is an artificial plant growth regulator that is widely used in plant tissue culture. Protocorm-like bodies (PLBs) induced by TDZ serve as an efficient and rapid in vitro regeneration system in Rosa species. Despite this, the mechanism of PLB induction remains relatively unclear. TDZ, which can affect the level of endogenous auxins and cytokinins, converts the cell fate of rhizoid tips and triggers PLB formation and plantlet regeneration in Rosa canina L. In callus-rhizoids, which are rhizoids that co-develop from callus, auxin and a Z-type cytokinin accumulated after applying TDZ, and transcription of the auxin transporter gene RcPIN1 was repressed. The expression of RcARF4, RcRR1, RcCKX2, RcCKX3, and RcLOG1 increased in callus-rhizoids and rhizoid tips while the transcription of an auxin response factor (RcARF1) and auxin transport proteins (RcPIN2, RcPIN3) decreased in callus-rhizoids but increased in rhizoid tips. In situ hybridization of rhizoids showed that RcWUS and RcSERK1 were highly expressed in columella cells and root stem cells resulting in the conversion of cell fate into shoot apical meristems or embryogenic callus. In addition, transgenic XVE::RcWUS lines showed repressed RcWUS overexpression while RcWUS had no effect on PLB morphogenesis. Furthermore, higher expression of the root stem cell marker RcWOX5 and root stem cell maintenance regulator genes RcPLT1 and RcPLT2 indicated the presence of a dedifferentiation developmental pathway in the stem cell niche of rhizoids. Viewed together, our results indicate that different cells in rhizoid tips acquired regeneration competence after induction by TDZ. A novel developmental pathway containing different cell types during PLB formation was identified by analyzing the endogenous auxin and cytokinin content. This study also provides a deeper understanding of the mechanisms underlying in vitro regeneration in Rosa. PMID:27200031

    Full Text Available Kaj Winther,1 Anne Sophie Vinther Hansen,1 Joan Campbell-Tofte2 1Department of Nutrition, Exercise and Sports, University of Copenhagen, Frederiksberg C, Denmark; 2Coordinating Research Unit, Frederiksberg University Hospital, Copenhagen, Denmark Abstract: Rosa canina pseudo fruits, often referred to as rose hips, have been used as herbal medicine for more than 2,000 years, yet research has only recently begun to clarify specific mechanisms by which this plant product affects human health. Numerous compounds have been identified, and speculations of their bioactivity have implicated flavonoids, carotenoids, and fatty acids (FAs. With more than 4,500 representatives, flavonoids have been subjected to comprehensive research, with results that suggest various individual structures may be health-promoting compounds, also in rose hips. The importance of carotenoids from R. canina is currently being debated, because the demonstration of specific bioactivity among this group is presently less clear. The benefits of specific FAs have been investigated for decades, and several types of FAs are termed “essential” for human health. The specific mechanisms for bioactivity associated with three FAs that are abundant in R. canina fruits have been clarified in research. For example, linoleic acid, α-linolenic acid (mostly present in the seeds from R. canina and a galactolipid ((2S-1,2-di-O-[(9Z,12Z,15Z-octadeca-9-12-15-trienoyl]-3-O-β-d-galactopyranosyl glycerol, referred to as GOPO, have been shown to have anti-inflammatory properties. The aim of this review is to critically analyze the published literature on rose hip research, with emphasis on the broadness and varying significance of the publications. Initially, we describe the chemical ingredients of R. canina pseudo fruits, with some focus on what ingredients are found in the whole pseudo fruit and what we know is confined to the seeds (achene seeds, and/or the shells (hypanthium.

    The 80% aqueous acetone extracts from the fruit (50 mg/kg/d) and seeds (12.5 and 25 mg/kg/d) of Rosa canina L., but not from the pericarps, were found to show substantial inhibitory effect on the gain of body weight and/or weight of visceral fat without affecting food intake in mice for 2 weeks after administration of the extracts. With regard to the active constituents, the principal constituent, trans-tiliroside (0.1-10 mg/kg/d), potently inhibited the gain of body weight, especially visceral fat weight, and significantly reduced blood glucose levels after glucose loading (1 g/kg, ip) in mice. On the other hand, kaempferol and p-coumaric acid lacked such effect and kaempferol 3-O-beta-D-glucopyranoside tended to reduce the gain of body weight and visceral fat weight, but not significantly, at a dose of 10 mg/kg/d. These results indicate the importance of both kaempferol 3-O-beta-D-glucopyranoside and p-coumaroyl moieties for anti-obese effects. Furthermore, a single oral administration of trans-tiliroside at a dose of 10 mg/kg increased the expression of PPAR-alpha mRNA of liver tissue in mice.

    Pigeons given a simultaneous spatial discrimination reversal, in which a single reversal occurs at the midpoint of each session, consistently show anticipation prior to the reversal as well as perseveration after the reversal, suggesting that they use a less effective cue (time or trial number into the session) than what would be optimal to maximize reinforcement (local feedback from the most recent trials). In contrast, rats (Rattus norvegicus) and humans show near-optimal reversal learning on this task. To determine whether this is a general characteristic of mammals, in the present research, pigeons (Columba livia) and dogs (Canis familiaris) were tested with a simultaneous spatial discrimination mid-session reversal. Overall, dogs performed the task more poorly than pigeons. Interestingly, both pigeons and dogs employed what resembled a timing strategy. However, dogs showed greater perseverative errors, suggesting that they may have relatively poorer working memory and inhibitory control with this task. The greater efficiency shown by pigeons with this task suggests they are better able to time and use the feedback from their preceding choice as the basis of their future choice, highlighting what may be a qualitative difference between the species.

    We used PBPK (physiologically-based pharmacokinetic) modelling to investigate distribution, bioaccumulation and excretion of the seven POPs (persistent organic pollutants) CB-99, CB-153, HCB, oxychlordane, p,p'-DDE, BDE-47 and BDE-99 in 4 adult captive Greenland sledge dog (Canis familiaris) bitches fed minke whale (Balaenoptera acuterostrata) blubber for 500-635 days. The PBPK modelled POP concentrations in adipose tissue, liver, kidney and plasma were mostly within a factor 2 of actual measured tissue levels even for those at the lower concentration end. The excretion route for oxychlordane and CB-153 was modelled to be via faeces while lung alveolar excretion dominated for BDE-47, BDE-99, HCB, p,p'-DDE and CB-99. Furthermore the model suggested the retained mass of POPs after 500 and 635 days of exposure, respectively, to be relatively low despite these POPs being highly recalcitrant. The retention increased in the following order (% of total intake); p,p'-DDE (1%)tool in risk assessment of POPs in arctic mammals. PMID:26210746

Resultados. A los estudios histológicos y morfológicos las células de la glándula mamaria normal humana demostraron semejanzas con las células de la glándula mamaria normal canina. Se observó adhesión y proliferación de células normales en ambas especies por aproximadamente tres meses de cultivo. Las células normales de las especies humana y canina mostraron baja actividad de proliferación cuando se compararon con las cancerosas de las especies en estudio. Los grupos de células epiteloides que se adhirieron al sustrato de los dos cultivos tuvieron dependencia de las células estromales, porque en la medida que las células fibroblastoides se retiraron, las células epiteloides detuvieron su crecimiento. Conclusiones. Comparando los resultados obtenidos por medio de análisis inmuno-histoquímico de células normales de mujeres y perras fue posible observar cambios en el patrón de coloración en células cancerosas en ambas especies, demostrando que las estructuras relacionadas con la adhesión celular (desmosomas pueden estar alteradas.

    Full Text Available A leptospirose é uma grave zoonose associada às áreas de baixa renda dos centros urbanos. Embora roedores urbanos sejam considerados como principal reservatório para a leptospirose, o cão também pode desenvolver a doença e se tornar carreador assintomático. O objetivo do presente trabalho foi utilizar a metodologia estatística baseada na teoria de processos pontuais espaciais, buscando identificar a forma como se distribuem os cães sororreagentes para a leptospirose e seus determinantes de risco em uma vila na cidade de Curitiba. A análise do modelo possibilitou identificar as regiões de sobre-risco, onde o risco de soropositividade canina à leptospirose é significativamente maior. A relação significativa do efeito espacial no desenvolvimento da doença, além das variáveis estudadas, revela que não apenas um, mas a ação conjunta dos fatores relacionados ao animal, ao proprietário e ao ambiente influencia o risco maior da doença nos locais de maior efeito espacial. O resultado da análise indica claramente os territórios em maior risco na região da Vila Pantanal, possibilitando o planejamento de ações mais específicas e dirigidas a essas áreas em um contexto de vigilância da saúde.

Nel 2006 e 2007 sono stati testati i sieri di 449 cani provenienti dalla stessa zona. Trentuno animali (6,9% sono risultati positivi al test di immunofluorescenza indiretta (IFI. L'analisi dei fattori di rischio ha chiaramente dimostrato come il focolaio fosse limitato alla località di Calaone, situata nel comune di Baone (PD. Per verificare l'efficacia delle misure preventive adottate, nel 2010, 63 cani di Calaone sono stati campionati e i loro proprietari intervistati. In base alle informazioni rilasciate dai proprietari, la protezione dei cani nei confronti della leishmaniosi ha avuto inizio nel 2006 (66,7% dei cani protetti crescendo negli anni seguenti (90% dei cani protetti. Il valore di sieroprevalenza (4,2% della classe di cani di età più giovane (<5 anni è risultato significativamente minore di quello delle altre classi, dimostrando che gli animali nati dopo il 2006 hanno avuto meno probabilità di infettarsi. Inoltre, i valori di sieroprevalenza riferiti esclusivamente ai cani di Calaone sono risultati del 32,4% (23/71 nel 2006-2007 e 20,6% (13/63 nel 2010, mostrando una tendenza decrescente. I risultati ottenuti mostrano un alto livello di sensibilizzazione dei proprietari dei cani e sembrano evidenziare come l'uso pervasivo di collari e spot-on agisca positivamente nel ridurre l'intensità di circolazione di Leishmania infantum.

    Full Text Available La ehrlichiosis monocítica canina (EMC es causada por la infección de una rickettsia denominada Ehrlichia canis; este microorganismo se reproduce solamente en el citoplasma de los monocitos sanguíneos y macrófagos tisulares. La EMC ha sido reportada en todo el mundo, pero las frecuencias más altas se reportan en las regiones tropicales y subtropicales. La EMC no siempre es reconocida clínicamente, pues es difícil de diagnosticar debido a que los signos clínicos son variables, a que se presenta en diferentes fases y a la existencia de coinfecciones con otros patógenos transmitidos por garrapatas y otros agentes infecciosos. Las manifestaciones clínicas y las técnicas de diagnóstico tradicionales, como el diagnóstico hematológico y la demostración típica de mórulas de E. canis en el citoplasma de monocitos en frotis sanguíneos, se han utilizado para el diagnóstico de la EMC; sin embargo, las pruebas de diagnóstico por PCR y la serología mediante el uso de antígenos específicos son las pruebas más sensibles y específicas para el diagnóstico de la enfermedad. Este artículo presenta una revisión actualizada sobre el diagnóstico de la infección por E. canis en perros.

    The use of plant extract in the biosynthesis of nanoparticles (NPs) can be an eco-friendly approach and have been suggested as a possible alternative to classic methods namely physical and chemical procedures. In this study, the biosynthesis of zinc oxide (ZnO) NPs by both "conventional heating" (CH) and "microwave irradiation" (MI) methods has been reported. Stable and spherical ZnONPs were produced using zinc nitrate and flesh extract of Rosa canina fruit (rosehip) which was used as a precursor. The flesh extract acts as a reducing and capping agent for generation of ZnONPs. The structural, morphological and colloidal properties of the as-synthesized NPs have been confirmed by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), Fourier transform Infrared (FT-IR) and Dynamic Light Scattering (DLS). In comparison with the CH method, the MI method has some advantages such as significantly short reaction time (within 8min) owing to the high heating rate and thus the accelerated reaction rate. Both methods led to the synthesis of nearly identical NPs with respect to shape and size according to the results of DLS, XRD and SEM techniques. The possible mechanism for synthesis pathway has been proposed based on FT IR results, XRD patterns, potentiometric data and antioxidant activity. In addition, the antibacterial activity of as-prepared ZnONPs was investigated against several bacteria such as Listeria monocytogenes, Escherichia coli, Salmonella typhimurium. Moreover, the efficacy of ZnONPs to treat cancer cell lines were measured by means of cell viability test via MTT assay in which concentrations of 0.05 and 0.1mg/mL of ZnONPs induced a very low toxicity. Thus, the present investigation reveals that ZnONPs have the potential for various medical and industrial applications.

    Previous research on humans and animals suggests that the analysis of sleep patterns may reliably inform us about welfare status, but little research of this kind has been carried out for non-human animals in an applied context. This study explored the use of sleep and resting behaviour as indicators of welfare by describing the activity patterns of dogs (Canis lupus familiaris) housed in rescue shelters, and comparing their sleep patterns to other behavioural and cognitive measures of welfare. Sleep and activity patterns were observed over five non-consecutive days in a population of 15 dogs. Subsequently, the characteristics of sleep and resting behaviour were described and the impact of activity on patterns of sleep and resting behaviour analysed. Shelter dogs slept for 2.8% of the day, 14.3% less than previously reported and experienced less sleep fragmentation at night (32 sleep bouts). There were no statistically significant relationships between behaviours exhibited during the day and sleep behaviour. A higher proportion of daytime resting behaviour was significantly associated with a positive judgement bias, less repetitive behaviour and increased time spent coded as ‘relaxed’ across days by shelter staff. These results suggest that, in the context of a busy shelter environment, the ability to rest more during the day could be a sign of improved welfare. Considering the non-linear relationship between sleep and welfare in humans, the relationship between sleep and behavioural indicators of welfare, including judgement bias, in shelter dogs may be more complex than this study could detect.

    Background: Sporadic Alzheimer’s Disease (SAD) is caused by genetic risk factors, aging and oxidative stresses. The herbal extract of Rosa canina (R. canina), Tanacetum vulgare (T. vulgare) and Urtica dioica (U. dioica) has a beneficial role in aging, as an anti-inflammatory and anti-oxidative agent. In this study, the neuroprotective effects of this herbal extract in the rat model of SAD was investigated. Methods: The rats were divided into control, sham, model, herbal extract -treated and ethanol-treated groups. Drug interventions were started on the 21st day after modeling and each treatment group was given the drugs by intraperitoneal (I.P.) route for 21 days. The expression levels of the five important genes for pathogenesis of SAD including Syp, Psen1, Mapk3, Map2 and Tnf-α were measured by qPCR between the hippocampi of SAD model which were treated by this herbal extract and control groups. The Morris Water Maze was adapted to test spatial learning and memory ability of the rats. Results: Treatment of the rat model of SAD with herbal extract induced a significant change in expression of Syp (p=0.001) and Psen1 (p=0.029). In Morris Water Maze, significant changes in spatial learning seen in the rat model group were improved in herbal-treated group. Conclusion: This herbal extract could have anti-dementia properties and improve spatial learning and memory in SAD rat model. PMID:27563424

    Full Text Available Kristian Marstrand,1 Joan Campbell-Tofte2 1Department of Orthopaedic Surgery, Elverum Hospital, Elverum, Norway; 2Coordinating Research Unit, Frederiksberg University Hospital, Frederiksberg, Copenhagen, Denmark Abstract: Rosa canina fruits (often known as rose hip have been used in herbal remedies since ancient times. On the basis of anecdotal reports about the effects of rose hip preparations on human health and citations to the same in ancient texts, in vitro and in vivo studies have been conducted that have made it possible to learn about some active ingredients in rose hip, as well as how the component compounds might exert their effects. From such studies, it has been documented that there is a great variation in active ingredients when comparing different rose hip products. Factors which affect the quality and quantity of active ingredients in the rose hip products include the subspecies of the particular R. canina from which the fruits are harvested, the environment during plant growth, time of harvesting, and the amount of seeds and shells/husks incorporated into the preparation. Studies in animals and in humans are of great importance for determining the true bio-effects of rose hip. Such in vivo studies that have only been performed during the last 2 decades indicate that the treatment of patients with different types of joint disease with rose hip powder based on a subspecies of R. canina (Lito containing a certain galactolipid (GOPO can alleviate pain, improve daily activity, and even reduce the consumption of regular pain relievers. As several rose hip components have been shown to be anti-inflammatory, it is suggested that anti-inflammatory mechanisms might explain some reductions in symptoms associated with administering rose hip to arthritic conditions. Although the number of publications of randomized and placebo-controlled clinic studies with rose hip is small, the overriding evidence is that the anti-inflammatory effects from

    organization of ancestral and modern mammal communities. Thus, it is important to identify what extinct carnivore species may have been social and to determine when, where and under which environmental contexts they evolved. The first step is to establish if there is an association between morphological traits, susceptible of being preserved in the fossil record, and differences in the degree of sociality of present day carnivores. The aim of this research was to establish if there is an association between variation in shape and variables related to mechanical properties of the skulls, and differences in sociality level, diet and sex in modern canids. The sample included 972 specimens of 33 canid species. We analyzed the shape of the lateral side of the cranium, zygomatic arch, dentary bone and mandibular corpus, as well as 20 variables related to mechanical properties of the skull. Results suggest that hypercarnivorous social canids have shapes and mechanical properties that are different from other modern canids. We found that morphological variation is not affected by sex. Results may be used to identify extinct Caninae species that were social and hypercarnivorous. Results also suggest that the evolution of sociality is dependent on phylogenetic relationships and ecological context, particularly the abundance of large prey and the presence of sympatric carnivores.

    This work reports for the first time the direct electron transfer of the Canis familiaris cytochrome P450 2D15 on glassy carbon electrodes to provide an analytical tool as an alternative to P450 animal testing in the drug discovery process. Cytochrome P450 2D15, that corresponds to the human homologue P450 2D6, was recombinantly expressed in Escherichia coli and entrapped on glassy carbon electrodes (GC) either with the cationic polymer polydiallyldimethylammonium chloride (PDDA) or in the presence of gold nanoparticles (AuNPs). Reversible electrochemical signals of P450 2D15 were observed with calculated midpoint potentials (E1/2) of −191 ± 5 and −233 ± 4 mV vs. Ag/AgCl for GC/PDDA/2D15 and GC/AuNPs/2D15, respectively. These experiments were then followed by the electro-catalytic activity of the immobilized enzyme in the presence of metoprolol. The latter drug is a beta-blocker used for the treatment of hypertension and is a specific marker of the human P450 2D6 activity. Electrocatalysis data showed that only in the presence of AuNps the expected α-hydroxy-metoprolol product was present as shown by HPLC. The successful immobilization of the electroactive C. familiaris cytochrome P450 2D15 on electrode surfaces addresses the ever increasing demand of developing alternative in vitromethods for amore detailed study of animal P450 enzymes' metabolism, reducing the number of animals sacrificed in preclinical tests.

    This work reports for the first time the direct electron transfer of the Canis familiaris cytochrome P450 2D15 on glassy carbon electrodes to provide an analytical tool as an alternative to P450 animal testing in the drug discovery process. Cytochrome P450 2D15, that corresponds to the human homologue P450 2D6, was recombinantly expressed in Escherichia coli and entrapped on glassy carbon electrodes (GC) either with the cationic polymer polydiallyldimethylammonium chloride (PDDA) or in the presence of gold nanoparticles (AuNPs). Reversible electrochemical signals of P450 2D15 were observed with calculated midpoint potentials (E1/2) of −191 ± 5 and −233 ± 4 mV vs. Ag/AgCl for GC/PDDA/2D15 and GC/AuNPs/2D15, respectively. These experiments were then followed by the electro-catalytic activity of the immobilized enzyme in the presence of metoprolol. The latter drug is a beta-blocker used for the treatment of hypertension and is a specific marker of the human P450 2D6 activity. Electrocatalysis data showed that only in the presence of AuNps the expected α-hydroxy-metoprolol product was present as shown by HPLC. The successful immobilization of the electroactive C. familiaris cytochrome P450 2D15 on electrode surfaces addresses the ever increasing demand of developing alternative in vitromethods for amore detailed study of animal P450 enzymes' metabolism, reducing the number of animals sacrificed in preclinical tests.

    Full Text Available As pyometra is recognized as one of the main causes of disease and death in the bitch the purposes of this study were to evaluate microbiological and histopathological aspects of canine pyometra and to research the virulence factors of the E. coli isolates identifying possible risks to human health. The microbiological isolation from the intrauterine contents of 100 dogs with pyometra was carried out and the virulence factors in the E. coli strains were identified using PCR method. This study also consisted of the counting of microorganisms colonies forming units in samples of intrauterine content, tests of antimicrobial susceptibility of the E. coli isolates and the histological examination of the uterus. E. coli was the most prevalent microorganism isolated (76.6% and 120 strains (79.5% were positive for sfa, 86 (56.9% were positive for cnf, 87 (57.6% were positive for pap, 52 (34.4% were positive for hly, 51 (33.8% were positive for iuc and 5 (3.3% were positive for afa genes. One observed more sensitivity of E. coli to norfloxacin, polimixin B, sulphazotrin, chloranfenicol and enrofloxacin. In 42% of the samples of uterine walls where microorganisms were isolated, the sizes of the areas of the inflammatory responses corresponded to 39-56%. Virulence factors were identified in 98.0% of the strains evaluated, demonstrating a high frequency of potentially pathogenic E. coli. It must be considered that dogs are animals that are living in close proximity to man for thousands of years and have an important role in the transmission of E. coli to other animals and to man.A piometra é uma enfermidade da cadela adulta, sendo a doença reconhecida como uma das causas mais comuns de morte desta espécie animal.

    Full Text Available La brucelosis canina, causada por Brucella canis, provoca epididimitis, atrofia testicular y esterilidad en los perros, mientras que en las hembras el síntoma principal es el aborto. La transmisión al hombre puede ser por contacto con el semen, orina, y/o fetos abortados de animales infectados. El presente estudio de tipo observacional de corte transversal, se realizó en caninos de barrios y asentamientos con alto índice de necesidades básicas insatisfechas (NBI en 8 áreas de la ciudad de Buenos Aires. Se estudiaron 219 perros, 184 hembras y 35 machos, que fueron negativos a la prueba de aglutinación con antígeno tamponado (BPAT, que descartó la infección con especies lisas del género Brucella. Sedetectaron anticuerpos anti-B. canis en 16 perros (7.3%, 9 hembras y 7 machos, este último dato es relevante ya que la orina de los machos es considerada uno de los medios de diseminación de la infección. Aunque sólo se pudieron tomar hemocultivos a 175 animales, en 3 (2 hembras y un macho se aislaron B. canis.

    Full Text Available The present study reports the first outbreak of autochthonous canine visceral leishmaniasis in Florianópolis, Santa Catarina, southern Brazil. Following the report of two cases of CVL, the Control Center of Zoonotic Diseases conducted a serological survey by ELISA and IFAT assays in seven districts of the Santa Catarina Island. Eleven seropositive dogs of autochthonous transmission were used in the present study. Infection by Leishmania sp. was confirmed by parasitological examination of bone marrow, liver, spleen and lymph nodes, culture in Schneider's medium and PCR. Leishmania sp. isolates were characterized by PCR-RFLP and hybridization with specific probes, allowing for the identification of Leishmania infantum. Autochthonous transmission of this disease in an area with high tourist traffic presents a major public health concern and signifies the emergence of an important zoonosis in southern Brazil. Therefore, the implementation of surveillance and control measures is imperative to prevent the spread of the disease among the canine population as well as transmission to the human population.O presente estudo relata o primeiro surto autóctone de leishmaniose visceral canina (LCV em Florianópolis, Santa Catarina, Brasil.

    Full Text Available Abstract Background Multiple hybridization events gave rise to pentaploid dogroses which can reproduce sexually despite their uneven ploidy level by the unique canina meiosis. Two homologous chromosome sets are involved in bivalent formation and are transmitted by the haploid pollen grains and the tetraploid egg cells. In addition the egg cells contain three sets of univalent chromosomes which are excluded from recombination. In this study we investigated whether differential behavior of chromosomes as bivalents or univalents is reflected by sequence divergence or transcription intensity between homeologous alleles of two single copy genes (LEAFY, cGAPDH and one ribosomal DNA locus (nrITS. Results We detected a maximum number of four different alleles of all investigated loci in pentaploid dogroses and identified the respective allele with two copies, which is presumably located on bivalent forming chromosomes. For the alleles of the ribosomal DNA locus and cGAPDH only slight, if any, differential transcription was determined, whereas the LEAFY alleles with one copy were found to be significantly stronger expressed than the LEAFY allele with two copies. Moreover, we found for the three marker genes that all alleles have been under similar regimes of purifying selection. Conclusions Analyses of both molecular sequence evolution and expression patterns did not support the hypothesis that unique alleles probably located on non-recombining chromosomes are less functional than duplicate alleles presumably located on recombining chromosomes.

    The effect of the addition of natural antioxidants from strawberry tree (Arbutus unedo L.; AU) and dog rose (Rosa canina L.; RC), in frankfurters elaborated with or without the addition of antioxidant additives (sodium ascorbate and nitrite) was studied. Six different types of experimental frankfurters were prepared depending on the addition of phenolic-rich extracts from RC and AU and the presence (P) or absence (C) of antioxidant additives. Thiobarbituric acid reactive substances (TBARS)-numbers signiifcantly increased during chilled storage of C-frankfurters while additives and fruit phenolics inhibited lipid oxidation in P-frankfurters. The amount of protein carbonyls signiifcantly increased in all treatments except in P-AU frankfurters. The discoloration process that occurred during the chilled storage was reduced by the addition of substances with proven antioxidant activity (P-frankfurters). Texture characteristics as hardness, springiness, cohesiveness and gumminess also suffered a signiifcant deterioration in C-frankfurters. The use of phenolic fruit extracts in combination with traditional antioxidant additives is a successful strategy to enhance the oxidative stability of frankfurters without modifying their color and texture properties.

The extract was submitted to: -2 °C for 12 hours; 4 °C for 12 hours; 40 °C for 15 minutes, 60 °C for 15 minutes, 80 °C for 15 minutes and 100 °C for 2 minutes, after which the antioxidant activity and the color (CIELab parameters were measured. Three sets of extracts were kept for 2 weeks at -2 °C; 4 °C and 25 - 30 °C and afterwards the parameters mentioned above were measured once again. Moreover, the total content of polyphenols was determined by Folin-Ciocalteu method. The results were expressed in mg gallic acid equivalents per liter. The antioxidant activity was determined using the method based on the interaction with the ABTS radical, the results being expressed in mmol trolox equivalent per liter. Thermal treatments have not influenced antioxidant activity, but have significantly affected the extract by increasing its luminosity and changing the red/green parameter towards more red tones, while storage at -2 °C caused the decrease of yellowness. Storage at 4 °C was found to be optimal for the preservation of the antioxidant activity.

  8. Point Topography and Within-Session Learning Are Important Predictors of Pet Dogs’ (Canis lupus familiaris Performance on Human Guided Tasks

    Directory of Open Access Journals (Sweden)

    Dorey, Nicole R.

    2013-07-01

    Full Text Available Pet domestic dogs (Canis lupus familiaris are generally considered successful on object choice tasks, reliably following human points to a target. However, defining the specific topography of the point types utilized and assessing the potential for dogs to generalize their responses across similar point types has received little attention. In Experiment 1, we assessed pet dogs’ performance on an object choice task utilizing nine different point types that varied across the dimensions of movement, duration, and distance. These dimensions reliably predicted the performance of pet dogs on this task. In Experiment 2, pet dogs presented with nine different point types in the order of increasing difficulty performed better on more difficult point types than both naive dogs and dogs experiencing the nine points in the order of decreasing difficulty. In Experiment 3, we manipulated the attentional state of the experimenter (as in perspective taking studies and found that human orientation was not a strong predictor of performance on pointing tasks. The results of this study indicate that dogs do not reliably follow all point types without additional training or experience. Furthermore, dogs appear to continuously learn about the dimensions of human points, adjusting their behavior accordingly, even over the course of experimental testing. These findings bring claims of pet dogs’ spontaneous success on pointing tasks into question. The ability to learn about, and respond flexibly to, human gestures may benefit pet dogs living in human homes more than a spontaneous responsiveness to specific gesture types.

Entre as afecções que acometem a próstata desses animais, a mais frequente é a hiperplasia prostática benigna (HPB. As neoplasias prostáticas, apesar de menos frequentes, são altamente malignas e um diagnóstico tardio está associado a um prognóstico ruim. Os principais métodos de diagnóstico das enfermidades prostáticas em cães incluem um exame clínico detalhado, ultrassonografia, punção aspirativa e biópsia. A utilização de biomarcadores séricos vem sendo estudada como uma maneira de se detectar a doença precocemente, evitando possíveis complicações no quadro clínico dos pacientes. Assim, estudos visando ao diagnóstico precoce de prostatopatias caninas, especialmente o câncer prostático, são cruciais para um tratamento eficaz e melhora da qualidade de vida do animal acometido.Prostatic diseases are common in older dogs, developing after sexual maturity. The most common affecting canine prostate is benign prostatic hyperplasia (BPH. Although less frequent, prostatic neoplasias are highly malignant, and a late diagnosis is closely associated with a poor prognosis. The main methods of diagnosis of the canine prostatic disease include a detailed clinical exam, ultrasound, prostatic fine-needle aspirate and biopsy. Studies towards early diagnosis of this condition are crucial for effective treatment and improvement of quality of life of affected animals. The use of biomarkers has been studied for early detection of the disease, avoiding possible complications in clinical patients.

    In October 2009, during a Karenia brevis red tide along the Texas coast, millions of dead fish washed ashore along the 113-km length of Padre Island National Seashore (PAIS). Between November 2009 and January 2010, at least 12 coyotes (Canis latrans) and three domestic dogs (Canis familiaris) died or were euthanized at PAIS or local veterinary clinics because of illness suspected to be related to the red tide. Another red tide event occurred during autumn 2011 and, although fewer dead fish were observed relative to the 2009 event, coyotes again were affected. Staff at PAIS submitted carcasses of four coyotes and one domestic dog from November 2009 to February 2010 and six coyotes from October to November 2011 for necropsy and ancillary testing. High levels of brevetoxins (PbTxs) were measured by enzyme-linked immunosorbent assay in seven of the coyotes and the dog, with concentrations up to 634 ng PbTx-3 eq/g in stomach contents, 545 ng PbTx-3 eq/g in liver, 195 ng PbTx-3 eq/g in kidney, and 106 ng PbTx-3 eq/mL in urine samples. Based on red tide presence, clinical signs, and postmortem findings, brevetoxicosis caused by presumptive ingestion of toxic dead fish was the likely cause of canid deaths at PAIS. These findings represent the first confirmed report of terrestrial mammalian wildlife mortalities related to a K. brevis bloom. The implications for red tide impacts on terrestrial wildlife populations are a potentially significant but relatively undocumented phenomenon.

Diversos padrões morfológicos de distribuição de grânulos subendoteliais de IgG e IgM foram identificados nos capilares glomerulares: global, segmentar, difuso ou focal. A intensidade da reação imunoistoquímica da IgG, medida pelo teste exato de Fisher não diferiu entre os grupos sintomáticos e assintomáticos e a intensidade de reação da IgM foi diferente entre os grupos (P<0,01. Depósitos de IgM nas células mesangiais e no infiltrado inflamatório raramente foram visualizados, no entanto as reações IgG foram freqüentemente visualizadas nesses locais. Concluiu-se que as reações de IgM foram mais intensas que as reações de IgG na LV canina e caracterizam-se pela distribuição de grânulos subendoteliais nos capilares glomerulares.

    Full Text Available O cão doméstico desempenha importante papel como reservatório na transmissão da leishmaniose visceral ao homem, zoonose de grande importância em saúde pública. Realizou-se avaliação epidemiológica da leishmaniose visceral em 1.112 cães domiciliados no município de Poxoréo, estado do Mato Grosso e observou-se prevalência de 7,8%. Observou-se ainda associação estatisticamente significativa entre a prevalência de leishmaniose visceral canina e as variáveis faixa etária, presença de sinais clínicos e presença de outra espécie animal co-habitando com os cães avaliados, tendo sido as galinhas mais freqüentemente observadas entre os animais soropositivos. O sexo, a coleta de lixo domiciliar bem como a renda familiar não apresentaram associação estatisticamente significativa com a prevalência da leishmaniose visceral canina. A análise dos resultados sugere que cães com idade superior a sete anos e a , presença de outra espécie animal co-habitando com os cães podem ser fatores de risco para a leishmaniose visceral canina.Dogs play an important role as reservoir in the domestic cycle of visceral leishmaniasis, a serious public health problem. An epidemiological survey in 1,112 dogs was conducted at the Municipality of Poxoréo State of Mato Grosso, Brazil, using indirect immunofluorescence antibody test where the prevalence was 7.8%. Significant association was found between prevalence of canine visceral leishmaniasis and age of the dogs. Clinical signs and presence of other animals in the backyard, like chicken being more likely associated with seropositivity. Gender, garbage collection in the residence and family financial income were not associated with visceral leishmaniasis prevalence. Analysis of the results suggests that dogs aging more than 7 years and presence of another animal species co-inhabiting with the dogs may be risk factors for canine visceral leishmaniasis.

    There are several reports of Sarcocystis sarcocysts in muscles of dogs, but these species have not been named. Additionally, there are two reports of Sarcocystis neurona in dogs. Here, we propose two new names, Sarcocystis caninum, and Sarcocystis svanai for sarcocysts associated with clinical muscular sarcocystosis in four domestic dogs (Canis familiaris), one each from Montana and Colorado in the USA, and two from British Columbia, Canada. Only the sarcocyst stage was identified. Most of the sarcocysts identified were S. caninum. Sarcocysts were studied using light microscopy, transmission electron microscopy (TEM), and polymerase chain reaction. Based on collective results two new species, S. caninum and S. svanai were designated. Sarcocystis caninum and S. svanai were structurally distinct. Sarcocystis caninum sarcocysts were up to 1.2 mm long and up to 75 μm wide. By light microscopy, the sarcocyst wall was relatively thin and smooth. By TEM, the sarcocyst wall was "type 9", 1-2 μm thick, and contained villar protrusions that lacked microtubules. Bradyzoites in sections were 7-9 μm long. Sarcocysts of S. svanai were few and were identified by TEM. Sarcocystis svanai sarcocysts were "type 1", thin walled (< 0.5 μm), and the wall lacked villar protrusions but had tiny blebs that did not invaginate. DNA was extracted either from infected frozen muscle biopsies or formalin-fixed paraffin-embedded sections. Dogs were either singly infected with S. caninum or multiply co-infected with S. caninum and S. svanai (the result of a mixed infection) based on multilocus DNA sequencing and morphology. BLASTn analysis established that the sarcocysts identified in these dogs were similar to, but not identical to Sarcocystis canis or Sarcocystis arctosi, parasites found to infect polar bears (Ursus maritimus) or brown bears (Ursus arctosi), respectively. However, the S. caninum sequence showed 100% identify over the 18S rRNA region sequenced to that of S. arctica, a

    Full Text Available Yeasts are commensal organisms found in the skin, genital and gastrointestinal tracts, and other mucosa in mammalians. Candida spp has been frequently isolated from domestic and sylvan animals. Yeast isolation from vaginal mucus is frequent in women, especially of Candida genus. In canine females, however, studies about vaginal fungal microbiota are rare and the connection with estrous cycle is unknown. The purpose of this study was to isolate yeast 5 of Candida genus from healthy canine females and identify the isolated species, establishing their connection with estrous cycle phases. Two hundred twenty-four samples taken from vaginal mucus of 14 canine females were analyzed in this study. Candida spp was observed in 83 (37% from these samples; nine samples were taken in proestrus, 14 in oestrus, 31 in dioestrus, 24 in anoestrus and five samples were obtained during pregnancy. Candida parapsilosis the most frequently isolated specie (21.7%, followed by C. guillermondii (8.4%, C. kefir (6% and C. albicans (4.8%. We concluded that Candida spp is a commion component of healthy canine females' vaginal microbiota, and isolation varies according to the estrous cycle phase.As leveduras são organismos comensais da pele, trato genital e gastrointestinal, e de outras mucosas de mamíferos.

    . O número de diagnósticos de erliquiose aumentou consideravelmente a partir de 2000, sendo que 24,4% dos casos ocorreram em animais entre 13 e 24 meses de idade na cidade de Belo Horizonte e áreas peri-urbanas, verificando-se maior risco de infecção em animais que residiam em casas. Os sintomas mais freqüentes foram febre, anorexia, apatia, dor abdominal, linfadenopatia e dispnéia. Quanto às alterações hematológicas, 70,3% apresentaram anemia, 50% trombocitopenia e 30% leucopenia e a maioria das infecções por E. canis foi visualizada em monócitos. Os resultados apontam para a necessidade de maior atenção por parte dos clínicos e técnicos para a erliquiose canina uma vez que 35,9% dos cães atendidos com suspeita de hemoparasitoses apresentavam infecções por E. canis ou E. platys.

Seventy-one mongrel dogs naturally infected with Leishmania chagasi were obtained from two Brazilian endemic areas: João Pessoa, PB and Belo Horizonte, MG. The hepatic parasite load was determined and compared to granuloma formation. Liver fragments from all infected animals showed remarkable leishmaniotic granulomatous inflammatory reaction. Granulomas with variable size were constituted by macrophages (parasitized or not with amastigotes of L. chagasi, some epithelioid cells, small numbers of lymphocytes, plasma cells, and rare neutrophils. Asymptomatic dogs had higher numbers of granulomas than oligosymptomatic and symptomatic animals from both geographical regions. However, the average diametric size of granulomas was very heterogeneous in all groups, independently of the geographic region (P>0.05. Parasite tissue load did not show any difference among liver fragments of all animals, especially when considering the defined clinical status and/or their geographic origin.Descreve-se a formação de granulomas hepáticos na leishmaniose canina em animais com classificação clínica definida - assintomáticos, oligossintomáticos e sintomáticos.

    Full Text Available The aim of this study was to characterize the anti-inflammatory mode of action of botanical extracts from rosehip (Rosa canina, willow bark (Salix alba, and nettle leaf (Urtica dioica in an in vitro model of primary canine articular chondrocytes. Methods. The biological effects of the botanical extracts were studied in chondrocytes treated with IL-1β for up to 72 h. Expression of collagen type II, cartilage-specific proteoglycan (CSPG, β1-integrin, SOX-9, COX-2, and MMP-9 and MMP-13 was examined by western blotting. Results. The botanical extracts suppressed IL-1β-induced NF-κB activation by inhibition of IκBα phosphorylation, IκBα degradation, p65 phosphorylation, and p65 nuclear translocation. These events correlated with downregulation of NF-κB targets including COX-2 and MMPs. The extracts also reversed the IL-1β-induced downregulation of collagen type II, CSPG, β1-integrin, and cartilage-specific transcription factor SOX-9 protein expression. In high-density cultures botanical extracts stimulated new cartilage formation even in the presence of IL-1β. Conclusions. Botanical extracts exerted anti-inflammatory and anabolic effects on chondrocytes. The observed reduction of IL-1β-induced NF-κB activation suggests that further studies are warranted to demonstrate the effectiveness of plant extracts in the treatment of OA and other conditions in which NF-κB plays pathophysiological roles.

    Full Text Available La brucelosis canina, producida por Brucella canis, es una enfermedad asociada a problemas reproductivos y de carácter zoonótico. Estas bacterias son excretadas en orina, leche, fetos o semen de los animales infectados y la transmisión ocurre por contacto vía sexual, oral, nasal o conjuntival. El diagnóstico de rutina se realiza por serología, pero la confirmación requiere aislamiento del cultivo bacterial, lo cual es costoso y requiere laboratorios con nivel 3 de bioseguridad. Las técnicas moleculares son una posibilidad reconocida para determinar el ADN bacterial, con alta especificidad y sensibilidad. Este reporte evaluó como prueba de aplicación clínica una técnica de PCR desarrollada para cultivos bacteriales. A una hembra canina asintomática, con historia previa de la enfermedad, amamantando una camada sana de 4 días de nacidos, se le realizó la prueba serológica rápida en placa con 2ß-mercaptoetanol, hemocultivo y PCR, de leche y de sangre. Todas las pruebas fueron positivas a Brucella canis. Este es el primer reporte de diagnóstico en leche por PCR, lo que corrobora que animales clínicamente asintomáticos eliminan la bacteria por esta vía, lo que constituye un riesgo de infección para los neonatos y el riesgo zoonótico para veterinarios, propietarios del animal o personas que intervengan en el parto si no se toman medidas higiénicas preventivas.Canine brucellosis is a disease caused by Brucella canis that is associated to reproductive problems in dogs, and it is also known as zoonosis.

    Full Text Available A esporotricose é uma micose causada pelo Sporothrix schenckii e pouco frequente em cães. A confirmação diagnóstica é por isolamento fúngico em meio de cultura, mas este procedimento pode ser difícil em caninos infectados. Em virtude de ser rara nesta espécie, por possuir diagnóstico definitivo difícil e pela carência de relatos da doença no Nordeste brasileiro, o presente trabalho objetivou a descrição de um caso de esporotricose canina, na cidade de Mossoró, RN. Uma cadela, de três anos de idade, apresentava lesões cutâneas crônicas. O animal era alojado em quintal com areia, plantas e felinos peridomiciliados. O exame dermatológico demonstrou alopecia e nódulos subcutâneos cervicais. Exame citológico, raspado cutâneo para pesquisa de ácaro, sorologia para leishmaniose e cultura fúngica foram solicitados. O resultado sorológico foi não reagente e o raspado exibiu negatividade. Porém, a citologia evidenciou estruturas, no citoplasma de macrófagos, sugestivas de S. schenckii. O isolamento do fungo em cultura confirmou o diagnóstico de esporotricose. Fez-se o tratamento com itraconazol. A inclusão constante da esporotricose para o diagnóstico diferencial de pápulas, nódulos e ou úlceras cutâneas é fundamental na espécie canina.

MÉTODOS: Anéis de artéria coronária, com e sem o endotélio íntegro, foram imersos em solução de krebs e conectadas a um transdutor para aferição de força isométrica promovida por contração vascular. As artérias foram expostas a concentrações crescentes de polisorbato 80, amiodarona dissolvida em água, amiodarona dissolvida em polisorbato 80 e uma apresentação comercial da amiodarona (Cordarone®. Os experimentos foram conduzidos na presença e na ausência dos seguintes bloqueadores enzimáticos: apenas indometacina, Nômega-nitro-L-arginina associada à indometacina e apenas Nômega-nitro-L-arginina. RESULTADOS: O polisorbato 80 causou pequeno relaxamento não dependente do endotélio. O Cordarone®, a amiodarona dissolvida em água e em polisorbato 80 promoveram relaxamento dependente do endotélio, que foi de maior magnitude para a amiodarona dissolvida em polisorbato e para o Cordarone®. Apenas a associação de indometacina com a Nômega-nitro-L-arginina foi capaz de abolir o relaxamento dependente do endotélio provocado pela amiodarona dissolvida em polisorbato 80. CONCLUSÃO: Os resultados obtidos indicam que a vasodilatação promovida pela amiodarona em artérias coronárias caninas é causada principalmente pela estimulação da liberação de óxido nítrico e fatores endoteliais relaxantes dependentes das ciclo-oxigenases.OBJECTIVE: To assess the vasodilating effects of amiodarone on canine coronary arteries by using solutions of amiodarone dissolved in polysorbate 80 or water.

    Alpha-linolenic acid (ALA) is an essential n-3 PUFA; its n-3 LCPUFA derivatives EPA and DHA, which have diverse beneficial effects, are scarce in the human diet. In recent years nontraditional vegetable oils rich in ALA (up to 45%) have been developed as new alternatives to increase ALA consumption. This work evaluated the accretion of ALA, EPA and DHA into the phospholipids extracted from erythrocytes, liver, kidney, small intestine, heart, quadriceps and the brain in rats fed sunflower (SFO), canola (CO), Rosa canina (RCO), sacha inchi (Plukenetia volubilis, SIO) and chia (Salvia hispánica, ChO) oils. Five experimental groups (n = 12 per group) were fed for 21 days with SFO (1% ALA), CO (10% ALA), RCO (33% ALA), SIO (49% ALA), and ChO (64% ALA). SIO and ChO allowed higher ALA accretion in all tissues, except the brain, and a reduction in the content of arachidonic acid in all tissues except the brain. EPA was increased in erythrocytes, liver, kidney, small intestine, heart and quadriceps, but not in the brain. DHA was increased in the liver, small intestine and brain tissues. Our results demonstrate that ALA, when provided in significant amounts, can be converted into n-3 LCPUFA, mostly DHA in the liver and brain. It is suggested that oils rich in ALA, such as SIO and ChO, are good sources for obtaining higher tissue levels of ALA, also allowing its selective conversion into n-3 LCPUFA in some tissues of the rat.

    Full Text Available A leptospirose é uma grave zoonose associada às áreas de baixa renda dos centros urbanos. Embora roedores urbanos sejam considerados como principal reservatório para a leptospirose, o cão também pode desenvolver a doença e se tornar carreador assintomático. O objetivo do presente trabalho foi utilizar a metodologia estatística baseada na teoria de processos pontuais espaciais, buscando identificar a forma como se distribuem os cães sororreagentes para a leptospirose e seus determinantes de risco em uma vila na cidade de Curitiba. A análise do modelo possibilitou identificar as regiões de sobre-risco, onde o risco de soropositividade canina à leptospirose é significativamente maior. A relação significativa do efeito espacial no desenvolvimento da doença, além das variáveis estudadas, revela que não apenas um, mas a ação conjunta dos fatores relacionados ao animal, ao proprietário e ao ambiente influencia o risco maior da doença nos locais de maior efeito espacial. O resultado da análise indica claramente os territórios em maior risco na região da Vila Pantanal, possibilitando o planejamento de ações mais específicas e dirigidas a essas áreas em um contexto de vigilância da saúde.Leptospirosis is a serious zoonotic disease associated to low income areas of urban settings. Although rodents are considered the main reservoir for urban leptospirosis, dogs may also develop the disease and become asymptomatic carriers. The objective of this study was to apply a statistical method based on the spatial point processes theory for canine leptospirosis to identify how seroreagents dogs are spatially distributed and their risk determinants in a village of Curitiba city. The model analysis allowed the identification of over-risk regions, where seropositivity risk for canine leptospirosis was significantly higher, revealing that not just one, but the combination of animal, owner and environment factors influenced the disease

    为验证从狗蔷薇类原球茎克隆的RaWUS基因的功能,构建了组成型表达载体,并用根瘤农杆菌介导的叶盘转化法对烟草进行了遗传转化。通过除草剂草丁膦筛选,获得了转基因植株并对其进行了表型观察和RT.PCR分析。结果显示转基因烟草叶片形态和叶脉表现出形态变化,包括叶片浅裂、叶片边缘波浪状、叶脉紊乱,甚至叶片的主脉上有不定芽的产生等。RT-PCR分析表明,RaWUS基因仅仅在经过草丁膦筛选的抗性转基因烟草中强烈表达,在野生型烟草中没有表达。表明RaWUS基因已经被成功转入烟草中,并可能通过改变激素的水平和调控维管束的发育来影响叶片形状。%To analyze the function of RaWUS gene isolated from protocorm-like body of Rosa canina, constitutive expression vector was constructed and transformed into tobacco(Nicotiana tabacum) plants by using the leaf disc method mediated through Agrobacterium-tumefaciens. Screening with herbicide glufosinate resistance,transgenic tobacco plants were obtained. Their phenotypes were observed and RT-PCR was conducted. Transgenic tobacco plants exhibited changes in the leaf shape and veins, including lobed leaves,leaves with wary margin, disorder veins even ectopic bud formation on the leaves, and so on. The RT-PCR analysis indicated the RaWUS gene was expressed strongly in the regenerated plants which showed glyphosate resistance,but not in the wild-type tobacco. The results showed that RaWUS gene had been introduced into tobacco. Regulation of vascular tissue through changes in hormone levels was possible to alter leaf morphology. The effect of the gene on development of protocorm-like body and application in plant biotechnology were also discussed in this study.

    Full Text Available In this paper, we present spatial analysis of the association between all incidents cases of human Visceral Leishmaniasis and seropositive dogs, from 1994 to 1997 in Belo Horizonte, a large Brazilian city. We geocoded 158 human cases and 11,048 seropositive dogs and compared canine prevalence rates with Human Bayesian Incidence rates in the same areas. We also used Knox's test to evaluate the hypothesis of space-time clustering of human cases in the period. Additionally, we used Kernel's maps for seropositive dogs distribution and located the human cases in the resulting smooth maps. We concluded that human and dog rates are correlated. Also, the Visceral Leishmaniasis in Belo Horizonte spread quickly, but apart from the rates' magnitude, it has kept the same spatial pattern through time. We believe it is possible to use this technique to choose areas to implement control measures against Visceral Leishmaniasis in a more efficient way.Neste artigo, apresentamos uma análise espacial da associação entre todos os casos incidentes de leishmaniose visceral e em cães soropositivos ocorridos em Belo Horizonte no período de 1994 a 1997. Geocodificamos 158 casos humanos e 11.048 cães positivos, comparamos as taxas de prevalência canina por área e as taxas Bayesianas de incidência da doença humana nas mesmas áreas. Usamos o teste de Knox para testar a hipótese de cluster espaço temporal entre os casos humanos no período examinado. Adicionalmente, construímos Mapas de Kernel para cães soropositivos e sobrepusemos os casos humanos em quatro áreas. Os resultados apontam para correlação entre casos humanos e caninos. Além disso, a leishmaniose visceral espalhou-se rapidamente em Belo Horizonte, embora tenha mantido o mesmo padrão durante os anos analisados. Acreditamos ser possível o uso das técnicas empregadas para priorizar áreas onde as medidas de controle devem ser implementadas.

    Kin recognition requires the ability to discriminate between one's own genetic relatives and non-relatives. There are two mechanisms that aid in kin discrimination: phenotype matching and familiarity. Dogs may be a good model for assessing these mechanisms as dogs are a promiscuous social species with a keen sense of smell. Domestic dogs of both sexes were presented with two scents (close kin, distant-kin) and preference was assessed through three measures (latency to approach, number of visits, time spent). Experiment 1 explored the possibility of phenotype matching as subjects had no contact with sires, whose scent was presented alongside a control male's scent. Experiment 2 explored recognition of siblings raised with the subjects and then separated at seven weeks of age. Whereas female dogs in this experiment did not show a statistically significant preference, male dogs showed a preference for distant-kin when presented with sire and female sibling samples.

In the presented case the ante mortem clinical diagnosis of canine distemper virus (CDV infection could not be ideally performed due to the absence of typical signs of distemper, such as myoclonus and systemic signs accompanying the nervous signs. The definitive diagnosis of distemper encephalomyelitis was only carried out at post mortem through virus isolation in cell culture from fresh central nervous system (CNS fragments and CDV nucleoprotein gene detection in the CNS by RT-PCR.Descreve-se um caso de encefalomielite multifocal pela cinomose em um cão adulto. No caso apresentado o diagnóstico clínico da infecção pelo vírus da cinomose canina (CDV não pode ser adequadamente realizado devido à ausência de sinais típicos da enfermidade, tais como mioclonia e sinais sistêmicos. O diagnóstico definitivo somente foi possível post mortem pelo isolamento do CDV em cultivo celular a partir dos fragmentos frescos do sistema nervoso central (SNC e pela detecção do gene da nucleoproteína do CDV em fragmentos do SNC por meio da RT-PCR.

    Full Text Available Visceral leishmaniasis is a systemic infectious disease that can cause to a severe, potentially life-threatening chronic condition in humans. Risk factors for infection in urban areas have been associated with poor living conditions, the presence of sand fly vectors and infected pets. This study aimed to describe sand fly and canine infection in the neighborhoods of human visceral leishmaniasis occurrence in the city of Cuiabá, Mato Grosso State, central-western Brazil, reported between January 2005 and December 2006. A total of 1,909 sand flies were collected. They were predominantly males and the most frequent species were Lutzomyia cruzi (81.25%, Lutzomyia whitmani (13.88% and Lutzomyia longipalpis (2.62%. The sand fly density was not significantly correlated with the variation of environmental factors. The prevalence of canine visceral leishmaniasis in the neighborhoods studied was 26.82% and it was found that areas with high density of vectors coincided with areas of high prevalence of dogs and those with the highest rates of human cases. The study of vectors and other potential hosts are essential for a good understanding of visceral leishmaniasis and the related public health concerns, aiming at the prevention and control of leishmaniasis in the city of Cuiabá, Mato Grosso State.A leishmaniose visceral é uma doença infecciosa sistêmica, de evolução crônica grave, potencialmente fatal para o homem.

    Protocorm-like bodies (PLBs) can be efficiently induced by TDZ from Rosa canina rhizoids. More understandings on the molecular biological mechanism of PLBs induction contributes to the establishment of protocorm-like bodies protocols of cut roses. One important premise of the mechanism study in the molecular biological level is to quickly and accurately clone and screen the key genes during PLBs induction. On the basis of'conserved sequences' in 5' untranslated regions (5'UTR) of homologous genes with high scores of Malusx domestica, Prunus persica and Fragaria vesca, we designed the forward degenerate primers to directly isolate the cDNA 5'ends of PIN 1 (pin-formed) and PLT (plethora) of R, canina by PCR amplification using the cDNA template catalyzed by M-MLV reverse transcriptase. The results showed that there were some conserved fragments in the 5' rapid amplification of cDNA ends (5'UTR) of RcPINl, RcPLT and their homologous genes with high scores of Malusxdomestica, Fragaria vesca and Prunus persica, which indicated the above method was practicable. With this method, costly 5'RACE kits were entirely unnecessary because no homopolymer sequence and abridged anchor primers were to be introduced to the 5' ends of cDNA template, for genes from plants of Rosacease family. As a result, this method took advantages of speediness and economy. It is believed that this method will be a practical pathway and worthy reference to identify cDNA 5'ends for some Rosaceae plants.%狗蔷薇不定根可被噻苯隆(TDZ)高效诱导形成类原球茎,深入探讨其诱导阶段的分子生物学机制,有利于指导切花月季建立类似高效再生和遗传转化体系.快速、准确克隆和筛选狗蔷薇类原球茎发生的关键基因是进行分子生物学水平研究的一个重要前提.利用苹果(Malus×domestica)、桃(Prunus persica)和草莓(Fragaria vesca)高同源性基因5'UTR(非翻译区)的相对保守性,在其内保守区域设计上游简并引物,以M

    WUSCHEL is plant stem cell organizer gene, and its expression determines stem cell formation andmorphogenesis during plant development. We cloned its homologue gene from protocorm-like body in Rosa canina, and named it as RaWUS gene through homoiogy comparison of amino acid sequences alignment and phylogenetic analysis. A chemical inducible expression vector was constructed under XVE system. Under the system, overexpression of RaWUS gene was able to induce adventitious shoots from root tips of transgenic tobacco, and microobservation results showed that spherical meristem stem cell mass was produced in cortex in the root. Our research result suggests overexpression of RaWUS gene can transform parenchymatous cell into meristematic stem cell and induce shoot stem cell activity and development plasticity in the root.%WUSCHEL是植物干细胞命运的决定基因,在植物发育过程中WUSCHEL基因的表达决定着干细胞的形成和器官的发生.从狗蔷薇的类原球茎中克隆出其同源基因;经过对其进行蛋白质序列比对和系统发育分析,将其命名为Ra WUS基因.构建在XVE系统下的化学调控的表达载体.在该系统下,Ra WUS基因的超量表达能诱导转基因烟草根尖形成不定芽;同时显微观察表明,根部的皮层中有圆球形的分生组织干细胞团的产生.结果表明:Ra WUS基因的过量表达能够促使根的皮层中薄壁细胞转变成为分生组织干细胞而形成不定芽在根尖异位发生,说明其能够在植物的根尖中诱导茎尖分生组织干细胞的活性和发育的可塑性.

    Full Text Available The aim of this study was to determine the seroprevalence of Cutaneous Leishmaniasis (CL in dogs of Bela Vista do Paraiso, Parana state, compare the IFA and ELISA techniques and identify the vectors possibly involved in the cycle of the parasite. Were collected blood samples from 489 dogs that were subjected to detection of anti-Leishmania sp. by IFA and by ELISA. Were considered positive samples ³40 titers in IFA and for ELISA ³ 0.174 optical density. Among the samples analyzed, 222 (45.4% were positive by IFA and 189 (38.7% by ELISA. Comparing the tests were found 176 positive samples (36.0% and 254 negative (51.9% for both techniques. The sensitivity of ELISA was 79.3% and specificity was 95.1%. The global coefficient of the test was 87.0% with kappa coefficient of 0.75. Analysis of variables for dogs with positive serology by IFA showed significant differences regarding the absence of forests and lack of contact with other animal species. Positive sera by ELISA in dogs variables that showed significant differences were the type of riparian vegetation existing in the environment, the lack of garbage, open sewers and released directly into rivers or streams and garbage thrown on wasteland, burned or buried. The result obtained with the capture of sandflies was the predominance of Lutzomyia whitmani with 79.9% of the species collected. The result obtained with the capture of sandflies was the predominance of Lutzomyia whitmani with 79.9% of the species collected. The results showed that the LTA is widespread in the canine population of Bela Vista do Paraiso, and both the IFI and ELISA can be used for diagnosis. So the dog appears as a link between wild and peridomestic cycle of CL may become an amplifier of disease in this ecosystem.O trabalho teve como objetivo determinar a soroprevalência da Leishmaniose Tegumentar Americana (LTA canina no município de Bela Vista do Paraíso, Paraná, comparar as técnicas de imunofluorescência indireta

  2. Word generalization by a dog (Canis familiaris: is shape important?

    Emile van der Zee

    Full Text Available We investigated the presence of a key feature of human word comprehension in a five year old Border Collie: the generalization of a word referring to an object to other objects of the same shape, also known as shape bias. Our first experiment confirmed a solid history of word learning in the dog, thus making it possible for certain object features to have become central in his word comprehension. Using an experimental paradigm originally employed to establish shape bias in children and human adults we taught the dog arbitrary object names (e.g. dax for novel objects. Two experiments showed that when briefly familiarized with word-object mappings the dog did not generalize object names to object shape but to object size. A fourth experiment showed that when familiarized with a word-object mapping for a longer period of time the dog tended to generalize the word to objects with the same texture. These results show that the dog tested did not display human-like word comprehension, but word generalization and word reference development of a qualitatively different nature compared to humans. We conclude that a shape bias for word generalization in humans is due to the distinct evolutionary history of the human sensory system for object identification and that more research is necessary to confirm qualitative differences in word generalization between humans and dogs.

    We investigated the presence of a key feature of human word comprehension in a five year old Border Collie: the generalization of a word referring to an object to other objects of the same shape, also known as shape bias. Our first experiment confirmed a solid history of word learning in the dog, thus making it possible for certain object features to have become central in his word comprehension. Using an experimental paradigm originally employed to establish shape bias in children and human adults we taught the dog arbitrary object names (e.g. dax) for novel objects. Two experiments showed that when briefly familiarized with word-object mappings the dog did not generalize object names to object shape but to object size. A fourth experiment showed that when familiarized with a word-object mapping for a longer period of time the dog tended to generalize the word to objects with the same texture. These results show that the dog tested did not display human-like word comprehension, but word generalization and word reference development of a qualitatively different nature compared to humans. We conclude that a shape bias for word generalization in humans is due to the distinct evolutionary history of the human sensory system for object identification and that more research is necessary to confirm qualitative differences in word generalization between humans and dogs.

    Asthma is one of the most common chronic disorders and about 7% of the US population suffers from asthma. Initial response to allergy is associated with mediators like histamine, prostaglandin (PG) D2 and leukotriene (LT) C4. In asthmatic patients, 5-lipo-oxygenase (5-LO) pathway produces more LTC4 than the healthy people. Also, pro-inflammatory factors like interleukin (IL)-1, IL-6 and Tumor Necrosis Factor (TNF)-α play a remarkable role in bronchoconstriction. The common asthma medications ...

  13. Oxytocin receptor gene polymorphisms are associated with human directed social behavior in dogs (Canis familiaris.

    Directory of Open Access Journals (Sweden)

    Anna Kis

    Full Text Available The oxytocin system has a crucial role in human sociality; several results prove that polymorphisms of the oxytocin receptor gene are related to complex social behaviors in humans. Dogs' parallel evolution with humans and their adaptation to the human environment has made them a useful species to model human social interactions. Previous research indicates that dogs are eligible models for behavioral genetic research, as well. Based on these previous findings, our research investigated associations between human directed social behaviors and two newly described (-212AG, 19131AG and one known (rs8679684 single nucleotide polymorphisms (SNPs in the regulatory regions (5' and 3' UTR of the oxytocin receptor gene in German Shepherd (N = 104 and Border Collie (N = 103 dogs. Dogs' behavior traits have been estimated in a newly developed test series consisting of five episodes: Greeting by a stranger, Separation from the owner, Problem solving, Threatening approach, Hiding of the owner. Buccal samples were collected and DNA was isolated using standard protocols. SNPs in the 3' and 5' UTR regions were analyzed by polymerase chain reaction based techniques followed by subsequent electrophoresis analysis. The gene-behavior association analysis suggests that oxytocin receptor gene polymorphisms have an impact in both breeds on (i proximity seeking towards an unfamiliar person, as well as their owner, and on (ii how friendly dogs behave towards strangers, although the mediating molecular regulatory mechanisms are yet unknown. Based on these results, we conclude that similarly to humans, the social behavior of dogs towards humans is influenced by the oxytocin system.

  14. Live Births from Domestic Dog (Canis familiaris Embryos Produced by In Vitro Fertilization.

    Jennifer B Nagashima

    Full Text Available Development of assisted reproductive technologies (ART in the dog has resisted progress for decades, due to their unique reproductive physiology. This lack of progress is remarkable given the critical role ART could play in conserving endangered canid species or eradicating heritable disease through gene-editing technologies-an approach that would also advance the dog as a biomedical model. Over 350 heritable disorders/traits in dogs are homologous with human conditions, almost twice the number of any other species. Here we report the first live births from in vitro fertilized embryos in the dog. Adding to the practical significance, these embryos had also been cryopreserved. Changes in handling of both gametes enabled this progress. The medium previously used to capacitate sperm excluded magnesium because it delayed spontaneous acrosome exocytosis. We found that magnesium significantly enhanced sperm hyperactivation and ability to undergo physiologically-induced acrosome exocytosis, two functions essential to fertilize an egg. Unlike other mammals, dogs ovulate a primary oocyte, which reaches metaphase II on Days 4-5 after the luteinizing hormone (LH surge. We found that only on Day 6 are oocytes consistently able to be fertilized. In vitro fertilization of Day 6 oocytes with sperm capacitated in medium supplemented with magnesium resulted in high rates of embryo development (78.8%, n = 146. Intra-oviductal transfer of nineteen cryopreserved, in vitro fertilization (IVF-derived embryos resulted in seven live, healthy puppies. Development of IVF enables modern genetic approaches to be applied more efficiently in dogs, and for gamete rescue to conserve endangered canid species.

  15. Cross modal perception of body size in domestic dogs (Canis familiaris.

    Directory of Open Access Journals (Sweden)

    Anna M Taylor

    Full Text Available While the perception of size-related acoustic variation in animal vocalisations is well documented, little attention has been given to how this information might be integrated with corresponding visual information. Using a cross-modal design, we tested the ability of domestic dogs to match growls resynthesized to be typical of either a large or a small dog to size-matched models. Subjects looked at the size-matched model significantly more often and for a significantly longer duration than at the incorrect model, showing that they have the ability to relate information about body size from the acoustic domain to the appropriate visual category. Our study suggests that the perceptual and cognitive mechanisms at the basis of size assessment in mammals have a multisensory nature, and calls for further investigations of the multimodal processing of size information across animal species.

    Dogs have a unique capacity to follow human pointing, and thus it is often assumed that they can comprehend the referential meaning of such signals. However, it is still unclear whether dogs perceive human directional gestures as signals referring to a target object (indicating what to manipulate) or a spatial cue (indicating where to do something). In the present study, we investigated which of these alternative interpretations may explain dogs' responses to human pointing gestures in ostensive communicative and nonostensive cuing contexts. To test whether dogs select the cued object or the cued location, subjects were presented with 2 alternative object-choice trials. An experimenter first attracted the attention of the dog either by calling the dog's name and looking at it (ostensive condition, n = 24) or by clapping the hands (nonostensive condition, n = 24) then pointed at 1 of 2 different toy objects. Subsequently, the experimenter switched the location of the 2 target objects in full view of the dogs by grasping the objects and making a 180° turn. Dogs were then allowed to choose between the 2 objects. In the ostensive condition, dogs showed a significant bias toward the cued location compared with the nonostensive condition in which they performed at chance. These results suggest that pointing refers to a direction or location for dogs, but only if they are addressed with ostensive cues that indicate the communicative intention of the signaler.

  17. Do dogs (Canis lupus familiaris make counterproductive choices because they are sensitive to human ostensive cues?

    Directory of Open Access Journals (Sweden)

    Sarah Marshall-Pescini

    Full Text Available Dogs appear to be sensitive to human ostensive communicative cues in a variety of situations, however there is still a measure of controversy as to the way in which these cues influence human-dog interactions. There is evidence for instance that dogs can be led into making evaluation errors in a quantity discrimination task, for example losing their preference for a larger food quantity if a human shows a preference for a smaller one, yet there is, so far, no explanation for this phenomenon. Using a modified version of this task, in the current study we investigated whether non-social, social or communicative cues (alone or in combination cause dogs to go against their preference for the larger food quantity. Results show that dogs' evaluation errors are indeed caused by a social bias, but, somewhat contrary to previous studies, they highlight the potent effect of stimulus enhancement (handling the target in influencing the dogs' response. A mild influence on the dog's behaviour was found only when different ostensive cues (and no handling of the target were used in combination, suggesting their cumulative effect. The discussion addresses possible motives for discrepancies with previous studies suggesting that both the intentionality and the directionality of the action may be important in causing dogs' social biases.

    RESUMEN

    Las garrapatas revisten gran importancia en el campo biomédico por sus hábitos hematófagos y asociación con la transmisión de agentes patógenos a humanos y animales. El objetivo de esta investigación fue establecer las especies de garrapatas que parasitan perros en tres poblaciones del área rural del Caribe colombiano. Durante los meses de agosto y diciembre del año 2006 se realizó búsqueda activa de garrapatas sobre caninos domésticos de las localidades de El Campín, Sabanas del Potrero y Escobar Arriba, departamento de Sucre. Las garrapatas recolectadas fueron almacenadas en viales con etanol al 70% e identificadas empleando claves morfológicas de referencia para cada familia. Para la determinación de especie en la familia Argasidae se realizaron estimaciones morfométricas de estructuras externas. Se recolectaron 420 garrapatas a partir de 50 caninos infestados, de un total de 134 perros examinados, que corresponde a una tasa de infestación del 37,3%. Las garrapatas fueron identificadas como Rhipicephalus sanguineus, Rhipicephalus (Boophilus microplus y Amblyomma ovale pertenecientes a la familia Ixodidae, y Ornithodoros (Alectorobius puertoricensis de la familia Argasidae. La especie predominante fue R. sanguineus (92,1% en los estados de larva, ninfa y adulto, seguida por larvas de O. puertoricensis, que fueron halladas en menor número sobre caninos de las tres localidades. Se registra, por primera vez en América, el parasitismo de O. puertoricensis sobre caninos domésticos y se confirma su presencia en Colombia.

    ABSTRACT

    Ticks are very important from the biomedical point of view, by their hematophagic activity and their role in the transmission of pathogenic microorganisms to man and animals. The main goal of this work was to establish the tick species parasiting dogs in three rural localities of the Colombian Caribbean. From August to December 2006, an active search of ticks on dogs was carried out in the localities of El Campín, Sabanas del Potrero and Escobar Arriba, department of Sucre. The collected ticks were preserved into eppendorf tubes with 70% ethanol, and identified using standard morphological keys for each family. Argasid species were determined by measuring external morphological characters. Of 134 examined dogs in the three localities, 50 were found infested by ticks, representing a infestation rate of 37,3%. A total of 420 ticks were collected from dogs and identified as Rhipicephalus sanguineus, Rhipicephalus (Boophilus microplus, and Amblyomma ovale of the Ixodidae family, and Ornithodoros puertoricensis of the Argasidae family. R. sanguineus was the predominant species (92,1% in the stages of larva, nymph and adult, following by O. puertoricensis larvae recorded in low numbers in the three regions sampled. The tick O. puertoricensis is recorded for the first time as ectoparasite of domestic dogs in America. Additionally, the presence of this tick species is confirmed in Colombia.

    The pathology associated with acute, chronic, and recrudescent Babesia gibsoni infections was characterized in a group of 6 naturally or experimentally infected, spleen-intact and splenectomized dogs. All experimentally infected dogs became acutely parasitemic, lethargic, anemic, thrombocytopenic, and hemoglobinuric. Anatomic lesions associated, with the disease included diffuse nonsuppurative periportal and centrilobular hepatitis, multifocal necrotizing arteritis, membranoproliferative glomerulonephritis, reactive lymphadenopathy, diffuse erythrophagocytosis, and extramedullary hematopoiesis. The density of CD3+ lymphocytes within the liver sinusoids was markedly increased. Aggregates of large mononuclear cells with immunohistochemical features of activated macrophages were demonstrated in the central veins of the liver. Kupffer cells throughout the hepatic sinusoids appeared hypertrophic and prominent. The density of sinusoidal T lymphocytes, macrophages in central veins, and the degree of Kupffer cell hypertrophy were greatest in the splenectomized dogs. Multifocal deposits of IgM antibody were immunohistochemically demonstrated within the walls of inflamed arteries and renal glomeruli. The results of this study suggest that intense immunostimulation resulting in activation and expansion of T and B lymphocyte populations, macrophage recruitment and activation, vasculitis, glomerulonephritis and anemia contribute to the pathology associated with B. gibsoni infections.

The heart rate was investigated with 24-h ECG (Holter once during anoestrus, at 3, 5, 7 and 9 weeks of pregnancy, and at week 4 postpartum (lactation. However, at 9 weeks, the ECG could not be recorded for the fully 24 h in 4 of 5 dogs, because labour started and the dogs then appeared disturbed by the recordings. The results at this date are not included in the statistical comparison. The heart rate increased progressively during pregnancy and was still elevated at 4 weeks of lactation. During late pregnancy the difference in heart rates between daytime and nighttime became smaller, but the heart rate was significantly higher in daytime in all periods. In conclusion, the increased heart rates during pregnancy and lactation reflect increased demands on the cardiovascular system and may be important to consider in clinical practice.

    Mexico serves as a global model for advances in rabies prevention and control in dogs. The Mexican Ministry of Health (MMH) annual application of approximately 16 million doses of parenteral rabies vaccine has resulted in significant reductions in canine rabies during the past 20 years. One collateral parameter of rabies programs is dog population management. Enhanced public awareness is critical to reinforce responsible pet ownership. Surgical spaying and neutering remain important to prevent reproduction, but are impractical for achieving dog population management goals. GonaCon™, an anti-gonadotropin releasing hormone (GnRH) vaccine, was initially tested in captive female dogs on the Navajo Nation, 2008. The MMH led this international collaborative study on an improved formulation of GonaCon™ in captive dogs with local representatives in Hidalgo, Mexico in 2011. This study contained 20 bitches assigned to Group A (6 control), Group B (7 GonaCon™), and Group C (7 GonaCon™ and rabies vaccine). Vaccines were delivered IM. Animals were placed under observation and evaluated during the 61-day trial. Clinically, all dogs behaved normally. No limping or prostration was observed, in spite of minor muscle atrophy post-mortem in the left hind leg of dogs that received GonaCon™. Two dogs that began the study pregnant give birth to healthy pups. Dogs that received a GonaCon™ injection had macro and microscopic lesions consistent with prior findings, but the adverse injection effects were less frequent and lower in intensity. Both vaccines were immunogenic based on significant increases in rabies virus neutralizing antibodies and anti-GnRH antibodies in treatment Groups B and C. Simultaneous administration of GonaCon™ and rabies vaccine in Group C did not affect immunogenicity. Progesterone was suppressed significantly in comparison to controls. Future studies that monitor fertility through multiple breeding cycles represent a research need to determine the value of integrating this vaccine into dog rabies management. PMID:23871822

    A recent emerging technology, somatic cell nuclear transfer (SCNT), has been considered for conserving threatened or endangered species. Sapsaree is a native breed in Korea and has been designated as a Natural Monument. The aim of this study was to produce a Sapsaree by SCNT for breed conservation. Donor fibroblasts from a 9-year-old male Sapsaree were placed into the perivitelline spaces of enucleated in vivo matured oocytes and fused electrically. A total of 309 cloned embryos were transferred into the oviducts of 15 naturally synchronized recipients. Two recipients were diagnosed as pregnant, and each delivered one cloned puppy, both of which weighed 530 g. Overall, this study demonstrated that an endangered canine breed can be conserved by SCNT.

    The axial musculoskeletal system of quadrupedal mammals is not currently well understood despite its functional importance in terms of facilitating postural stability and locomotion. Here we examined the detailed architecture of the muscles of the vertebral column of two breeds of dog, the Staffordshire bull terrier (SBT) and the racing greyhound, which have been selectively bred for physical combat and high speed sprint performance, respectively. Dissections of the epaxial musculature of nine racing greyhounds and six SBTs were carried out; muscle mass, length, and fascicle lengths were measured and used to calculate muscle physiological cross-sectional area (PCSA), and to estimate maximum muscle potential for force, work and power production. The longissimus dorsi muscle was found to have a high propensity for force production in both breeds of dog; however, when considered in combination with the iliocostalis lumborum muscle it showed enhanced potential for production of power and facilitating spinal extension during galloping gaits. This was particularly the case in the greyhound, where the m. longissimus dorsi and the m. iliocostalis lumborum were estimated to have the potential to augment hindlimb muscle power by ca. 12%. Breed differences were found within various other muscles of the axial musculoskeletal system, particularly in the cranial cervical muscles and also the deep muscles of the thorax which insert on the ribs. These may also highlight key functional adaptations between the two breeds of dog, which have been selectively bred for particular purposes. Additionally, in both breeds of dog, we illustrate specialisation of muscle function by spinal region, with differences in both mass and PCSA found between muscles at varying levels of the axial musculoskeletal system, and between muscle functional groups.

    Full Text Available Helminths cause respiratory and gastrointestinal infections in animals, especially in neonates and young animals. Some species of helminth parasites of domestic animals have zoonotic potential, becoming a public health problem, especially when combined with lack of information about the population of these zoonosis and lack of control over of their hosts. This study aimed to identify and quantify the species of helminths from dogs that are not domiciled in the region of Cuiabá, in the Midwest region of Brazil. A total of 100 animals, from the Center for Zoonosis Control of Cuiabá were euthanized and necropsied for helminth searching. Overall 8,217 helminths were found in 85 animals identified in six species: Ancylostoma caninum, Ancylostoma. braziliense, Trichuris vulpis, Toxocara canis, Dirofilaria immitis and Dipylidium caninum. It was evidenced the wide distribution of helminths pathogenic to domestic dogs and especially with zoonotic potential as A. caninum, T. canis, D. caninum and D. immitis. The presence of D. immitis is an important finding, since it is a potentially zoonotic agent, however, this finding is considered sporadic.

    Full Text Available Objetive. To determine the distribution of ectoparasites in dogs in Panama. Materials and methods. There were surveyed 720 canines belonging to 57 communities. Results. The results showed that 84% of the dogs were infested with at least one species of ectoparasite. Dogs from lowlands showed a higher percentage of parasitism and a greater biodiversity of parasites than dogs from highlands. There were found seven species of ticks, four species of fleas, two species of lice, and one specie of botfly. The ticks Rhipicephalus sanguineus, Amblyomma cajennense, A. ovale and the flea Ctenocephalides felis were widespread; however Ixodes boliviensis and Pulex simulans showed a much narrower geographic distribution and they were found only in dogs from highlands. The flea species Rhopalopsyllus cacicus and the tick Haemaphysalis juxtakochi were found for the first time in panamanian dogs. Conclusions. The environmental situation in Panama, can encourage that wildlife ectoparasites parasitized dogs in absence of their native hosts. This condition may increase transmission risk of some diseases where the ticks and fleas are vectors.

  7. Influence of owners' attachment style and personality on their dogs' (Canis familiaris separation-related disorder.

    Directory of Open Access Journals (Sweden)

    Veronika Konok

    Full Text Available Previous research has suggested that owners' attitude to their family dogs may contribute to a variety of behaviour problems in the dog, and authors assume that dogs with separation-related disorder (SRD attach differently to the owner than typical dogs do. Our previous research suggested that these dogs may have an insecure attachment style. In the present study we have investigated whether owners' attachment style, personality traits and the personality of the dog influence the occurrence of SRD in the dog. In an internet-based survey 1508 (1185 German and 323 Hungarian dog-owners filled in five questionnaires: Demographic questions, Separation Behaviour Questionnaire (to determine SRD, Human and Dog Big Five Inventory and Adult Attachment Scale. We found that with owners' higher score on attachment avoidance the occurrence of SRD in the dog increases. Dogs scoring higher on the neuroticism scale were more prone to develop SRD. Our results suggest that owners' attachment avoidance may facilitate the development of SRD in dogs. We assume that avoidant owners are less responsive to the dog's needs and do not provide a secure base for the dog when needed. As a result dogs form an insecure attachment and may develop SRD. However, there may be alternative explanations of our findings that we also discuss.

  11. What counts for dogs (Canis lupus familiaris) in a quantity discrimination task?

    Science.gov (United States)

    Miletto Petrazzini, Maria Elena; Wynne, Clive D L

    2016-01-01

    Numerous studies have reported that animals reliably discriminate quantities of more or less food. However, little attention has been given to the relative salience of numerosity compared to the total amount of food when animals are making their choices. Here we investigated this issue in dogs. Dogs were given choices between two quantities of food items in three different conditions. In the Congruent condition, the total amount of food co-varied with the number of food items; in the Incongruent condition the total amount was pitted against the numerosity; and in the Controlled condition the total amount between the sets was equal. Results show that dogs based their choice on the total amount of edible food rather than on the number of food items, suggesting that, in food choice tasks, amount counts more than number. The presence of the largest individual item in a set did not bias dogs' choices. A control test excluded the possibility that dogs based their choices on olfactory cues alone.

Colorações histológicas como Hematoxilina-Eosina, van Gieson, Sudan, Azul de Toluidina e Ácido Periódico de Schiff também foram empregadas. Os dados revelaram uma eficácia de ordem de 85,3% no diagnóstico citopatológico, considerando-se os resultados histopatológicos como corretos. Em 4,0% dos casos somente a origem embrionária das neoplasias foi estabelecida. Em 1,3% das neoplasias apenas o prognóstico foi determinado; o diagnóstico citológico diferiu da histopatologia em 8,1% dos casos. Em dois casos (1,3% o diagnóstico citológico diferiu do histológico, mas um reexame determinou que o primeiro estava correto, o que elevou a sua eficácia para 86,6%. Entre as técnicas utilizadas, a punção aspirativa por agulha fina foi o melhor método para obter amostras. A citologia não foi adequada para o diagnóstico de neoplasias mamárias, dadas às variações morfológicas em diferentes áreas. A impressão em lâmina não é recomendada para análise de tumores mesenquimais e deve ser substituída pela citologia esfoliativa. O Wright revelou-se o método de coloração mais eficiente.

    Full Text Available Vaginitis is a rare disease in adult female dogs. However, knowledge regarding this illness is important because, if secondary to reproductive tract anomalies that go uncorrected, it can cause ascending uterine infections and, consequently, subfertility or even infertility. Usually, these infections are caused by Enterobacter or microorganisms from the urogenital inferior system, such as Staphylococcus spp, Streptococcus spp, Escherichia coli, Proteus spp, Pseudomonas aeruginosa, Pasteurella, etc. In some cases, vaginitis may be caused by primary infections with Brucella canis, which is zoonotic, or by canine herpesvirus; both of these agents have the potential to cause reproductive failure. The disease can occur in any age, breed or ovarian condition and can be identified by vaginal cytology, vaginoscopy and culture of vaginal secretions. The most common clinical signs are erythema of the vaginal mucous, vaginal discharge, pollakiuria, licking of the vulva and attraction of male dogs, independent of the phase of the estrous cycle. This disease is generally self-limiting, and the treatment, when necessary, consists of antibiotic therapy, vaginal cleaning with antiseptic and, eventually, surgical correction of predisposing abnormalities. A vaginite é uma afecção rara em cadelas adultas. É uma causa importante de subfertilidade ou infertilidade, quando secundária à anomalias do trato reprodutivo. Normalmente, são causadas por enterobactérias ou pela microbiota do sistema urogenital inferior, tais como Staphylococcus spp, Streptococcus spp, Escherichia coli, Proteus spp, Pseudomonas aeruginosa, Pasteurella, entre outras. Em alguns casos, pode ser primária como infecções por Brucella canis, a qual é uma zoonose ou herpesvírus canino, importante causa de falhas reprodutivas. A afecção acomete fêmeas de qualquer idade, raça ou condição ovariana. Os sinais clínicos envolvem mucosa vaginal hiperêmica, corrimento vulvar, polaquiúria, lambedura vulvar, e atração de machos independente da fase do ciclo estral. Pode ser diagnosticada por citologia vaginal, vaginoscopia e cultura da secreção. A enfermidade, muitas vezes, é autolimitante e o tratamento, quando necessário, e’ realizado com infusão vaginal de antissépticos ou antibióticos e, eventualmente, correção cirúrgica de anormalidades predisponentes.

    Full Text Available Las garrapatas revisten gran importancia en el campo biomédico por sus hábitos hematófagos y asociación con la transmisión de agentes patógenos a humanos y animales. El objetivo de esta investigación fue establecer las especies de garrapatas que parasitan perros en tres poblaciones del área rural del Caribe colombiano. Durante los meses de agosto y diciembre del año 2006 se realizó búsqueda activa de garrapatas sobre caninos domésticos de las localidades de El Campín, Sabanas del Potrero y Escobar Arriba, departamento de Sucre. Las garrapatas recolectadas fueron almacenadas en viales con etanol al 70% e identificadas empleando claves morfológicas de referencia para cada familia. Para la determinación de especie en la familia Argasidae se realizaron estimaciones morfométricas de estructuras externas. Se recolectaron 420 garrapatas a partir de 50 caninos infestados, de un total de 134 perros examinados, que corresponde a una tasa de infestación del 37,3%. Las garrapatas fueron identificadas como Rhipicephalus sanguineus, Rhipicephalus (Boophilus microplus y Amblyomma ovale pertenecientes a la familia Ixodidae, y Ornithodoros (Alectorobius puertoricensis de la familia Argasidae. La especie predominante fue R. sanguineus (92,1% en los estados de larva, ninfa y adulto, seguida por larvas de O. puertoricensis, que fueron halladas en menor número sobre caninos de las tres localidades. Se registra, por primera vez en América, el parasitismo de O. puertoricensis sobre caninos domésticos y se confirma su presencia en Colombia.Ticks are very important from the biomedical point of view, by their hematophagic activity and their role in the transmission of pathogenic microorganisms to man and animals. The main goal of this work was to establish the tick species parasiting dogs in three rural localities of the Colombian Caribbean. From August to December 2006, an active search of ticks on dogs was carried out in the localities of El Campín, Sabanas del Potrero and Escobar Arriba, department of Sucre. The collected ticks were preserved into eppendorf tubes with 70% ethanol, and identified using standard morphological keys for each family. Argasid species were determined by measuring external morphological characters. Of 134 examined dogs in the three localities, 50 were found infested by ticks, representing a infestation rate of 37,3%. A total of 420 ticks were collected from dogs and identified as Rhipicephalus sanguineus, Rhipicephalus (Boophilus microplus, and Amblyomma ovale of the Ixodidae family, and Ornithodoros puertoricensis of the Argasidae family. R. sanguineus was the predominant species (92,1% in the stages of larva, nymph and adult, following by O. puertoricensis larvae recorded in low numbers in the three regions sampled. The tick O. puertoricensis is recorded for the first time as ectoparasite of domestic dogs in America. Additionally, the presence of this tick species is confirmed in Colombia.

    Interspecific hybridization is relatively frequent in nature and numerous cases of hybridization between wild canids and domestic dogs have been recorded. However, hybrids between golden jackals (Canis aureus) and other canids have not been described before. In this study, we combined the use of biparental (15 autosomal microsatellites and three major histocompatibility complex (MHC) loci) and uniparental (mtDNA control region and a Y-linked Zfy intron) genetic markers to assess the admixed origin of three wild-living canids showing anomalous phenotypic traits. Results indicated that these canids were hybrids between golden jackals and domestic dogs. One of them was a backcross to jackal and another one was a backcross to dog, confirming that golden jackal–domestic dog hybrids are fertile. The uniparental markers showed that the direction of hybridization, namely females of the wild species hybridizing with male domestic dogs, was common to most cases of canid hybridization. A melanistic 3bp-deletion at the K locus (β-defensin CDB103 gene), that was absent in reference golden jackal samples, but was found in a backcross to jackal with anomalous black coat, suggested its introgression from dogs via hybridization. Moreover, we demonstrated that MHC sequences, although rarely used as markers of hybridization, can be also suitable for the identification of hybrids, as long as haplotypes are exclusive for the parental species.

    Genetic variation is necessary to maintain the ability of wild and domestic populations to genetically adapt to changed selective pressures. When relationships among individuals are known, conservation genetic management can be based on statistical pedigree analysis. Such approaches have traditionally focused on wild animal conservation breeding in captivity.

    Full Text Available Canine hypoadrenocorticism likely arises from immune-mediated destruction of adrenocortical tissue, leading to glucocorticoid and mineralocorticoid deficiency. In humans with autoimmune Addison's disease (AAD or autoimmune polyendocrine syndrome (APS, circulating autoantibodies have been demonstrated against enzymes associated with adrenal steroid synthesis. The current study investigates autoantibodies against steroid synthesis enzymes in dogs with spontaneous hypoadrenocorticism. Coding regions of canine CYP21A2 (21-hydroxylase; 21-OH, CYP17A1 (17-hydroxylase; 17-OH, CYP11A1 (P450 side-chain cleavage enzyme; P450scc and HSD3B2 (3β hydroxysteroid dehydrogenase; 3βHSD were amplified, cloned and expressed as 35S-methionine radiolabelled recombinant protein. In a pilot study, serum samples from 20 dogs with hypoadrenocorticism and four unaffected control dogs were screened by radio-immunoprecipitation assay. There was no evidence of reactivity against 21-OH, 17-OH or 3βHSD, but five dogs with hypoadrenocorticism showed immunoreactivity to P450scc compared with controls. Serum samples were subsequently obtained from 213 dogs diagnosed with hypoadrenocorticism and 110 dogs from a hospital control population. Thirty control dogs were randomly selected to establish a threshold for antibody positivity (mean + 3 × standard deviation. Dogs with hypoadrenocorticism were more likely to be P450scc autoantibody positive than hospital controls (24% vs. 1.2%, respectively; p = 0.0016. Sex was significantly associated with the presence of P450scc autoantibodies in the case population, with 30% of females testing positive compared with 17% of males (p = 0.037. Significant associations with breed (p = 0.015 and DLA-type (DQA1*006:01 allele; p = 0.017 were also found. This cross-sectional study indicates that P450scc autoantibodies are present in a proportion of dogs affected with hypoadrenocorticism.

    Fear and aggression are among the most prominent behavioural problems in dogs. Oxytocin has been shown to play a role in regulating social behaviours in humans including fear and aggression. As intranasal oxytocin has been found to have some analogous effects in dogs and humans, here we investigated the effect of oxytocin on dogs' behaviour in the Threatening Approach Test. Dogs, after having received intranasal administration of oxytocin (OT) or placebo (PL), showed the same reaction to an unfamiliar experimenter, but OT pretreated dogs showed a less friendly first reaction compared to the PL group when the owner was approaching. Individual differences in aggression (measured via questionnaire) also modulated dogs' first reaction. Moreover, subjects that received OT looked back more at the human (owner/experimenter) standing behind them during the threatening approach. These results suggest that oxytocin has an effect on dogs' response to the threatening cues of a human, but this effect is in interaction with other factors such as the identity of the approaching human and the 'baseline' aggression of the dogs.

    The cheetah and racing greyhound are of a similar size and gross morphology and yet the cheetah is able to achieve a far higher top speed. We compared the kinematics and kinetics of galloping in the cheetah and greyhound to investigate how the cheetah can attain such remarkable maximum speeds. This also presented an opportunity to investigate some of the potential limits to maximum running speed in quadrupeds, which remain poorly understood. By combining force plate and high speed video data of galloping cheetahs and greyhounds, we show how the cheetah uses a lower stride frequency/longer stride length than the greyhound at any given speed. In some trials, the cheetahs used swing times as low as those of the greyhounds (0.2 s) so the cheetah has scope to use higher stride frequencies (up to 4.0 Hz), which may contribute to it having a higher top speed that the greyhound. Weight distribution between the animal's limbs varied with increasing speed. At high speed, the hindlimbs support the majority of the animal's body weight, with the cheetah supporting 70% of its body weight on its hindlimbs at 18 m s(-1); however, the greyhound hindlimbs support just 62% of its body weight. Supporting a greater proportion of body weight on a particular limb is likely to reduce the risk of slipping during propulsive efforts. Our results demonstrate several features of galloping and highlight differences between the cheetah and greyhound that may account for the cheetah's faster maximum speeds. PMID:22723482

    Full Text Available El estudio de las diferencias individuales en el comportamiento de los perros domésticos tiene un gran valor aplicado dado que permite una mejor selección de los mismos para cumplir las variadas funciones que tienen en la sociedad humanacomo perros guía, policía, compañía, rescatistas de personas, etc. En el trabajo que se informa se presenta una revisión de estudios sobre diferencias individuales en perros, basada únicamente en las baterías conductuales que evalúan un conjunto de rasgos del temperamento. Con este objetivo se realiza una breve descripción de cada batería de pruebas utilizadas en la literatura, analizando las definiciones operacionales de las variables eva luadas y los diferentes tipos de estímulos utilizados. Los rasgos mayormente evaluados son: temerosidad, agresividad, disposición al entrenamiento y sociabilidad. La te merosidad, en general es evaluada a través de la respuesta del animal ante la aparición de un estímulo súbito que puede ser intenso o no, como por ejemplo la reacción frente a un ruido fuerte, la apertura de un paraguas, o la aparición repentina de una figura humana. La agresividad se mide a través de la reacción frentea la amenaza o provocación por parte de un humano, la sustracción de un objeto o la confrontación con un perro dominante. La disposición al entrenamiento es estudiada a través de la respuesta del animal frente a diferentes estímulos como el juego con un trapo o una cuerda, el ejercicio de devolución de un objeto o la obediencia frente a distintos comandos. Por último, la sociabilidad se evalúa con la aparición o el acercamiento de un humano desconocido o con la exposición a un perro no familiar. Se discuten además las limitaciones metodológicas de las baterías así como también los importantes usos aplicados de las mismas.

  7. An Investigation on Social Representations: Inanimate Agent Can Mislead Dogs (Canis familiaris in a Food Choice Task.

    Judit Abdai

    Full Text Available The nature of mental representation of others plays a crucial role in social interactions. Dogs present an ideal model species for the investigation of such mental representations because they develop social ties with both conspecifics and heterospecifics. Former studies found that dogs' preference for larger food quantity could be reversed by humans who indicate the smaller quantity. The question is whether this social bias is restricted to human partners. We suggest that after a short positive social experience, an unfamiliar moving inanimate agent (UMO can also change dogs' choice between two food quantities. We tested four groups of dogs with different partners: In the (1 Helper UMO and (2 Helper UMO Control groups the partner was an interactive remote control car that helped the dog to obtain an otherwise unreachable food. In the (3 Non-helper UMO and (4 Human partner groups dogs had restricted interaction with the remote control car and the unfamiliar human partners. In the Human partner, Helper UMO and Helper UMO Control groups the partners were able to revert dogs' choice for the small amount by indicating the small one, but the Non-helper UMO was not. We suggest that dogs are able to generalize their wide range of experiences with humans to another type of agent as well, based on the recognition of similarities in simple behavioural patterns.

Hookworms from dogs were generally smaller than these from foxes, but no other morphological differences could be found. These hookworms were qualified to species Uncinaria stenocephala on the ground of morphology of male. Genomic DNA samples have been isolated from these hookworms and segments of rDNA including part of small subunit of ribosomal RNA gene; internal transcribed spacer 1 (ITS1); 5.8 S ribosomal RNA; internal transcribed spacer 2 (ITS2) and part of large subunit of ribosomal RNA have been amplified and sequenced. Sequences from Uncinaria obtained both from foxes and dogs have shown very high similarity to the sequence of Uncinaria stenocephala, so all examined hookworms have been classified as belonging to this species.

    We have recently shown that repellency of the tick Rhipicephalus sanguineus sensu lato by the tick resistant dog breed, the beagle, is mediated by volatile organic compounds (VOCs) 2-hexanone and benzaldehyde present in beagle odour. Ectoparasite location of animal hosts is affected by variation in these odour components and their ratios. The aim of this study was to quantify the release rate, and the ratio, of 2-hexanone and benzaldehyde from beagles. The odour of three beagles was collected, for four days, over one week (day 0, day 1, day 4 and day 7). The compounds were identified using coupled high-resolution gas chromatography-mass spectrometry (GC-MS), and authentic standards of compounds were used to generate external calibration curves for quantification. Both compounds were found in all dogs on all days. The amount of benzaldehyde was always higher than that of 2-hexanone and so their ratio varied from unity, on average (over time) being 3.128±0.365, 1.902±0.390, 1.670±0.671ngmL(-1) for beagle 1, 2 and 3, respectively. There was no significant (pbenzaldehyde in beagle odour samples covering a 7-day period. This knowledge enables development of repellents to protect dogs from R. sanguineus s. l. infestation.

Uno de los mecanismos que se encuentra siempre en la adaptación cardiaca es la hipertrofia del miocardio. El grado de hipertrofia puede evaluarse midiendo la masa miocárdica ventricular izquierda. Sin embargo este parámetro evalúa la cantidad de hipertrofia, pero no la manera en que ésta se distribuye. Dicha distribución puede calcularse por medio del índice ecocardiográfico conocido como espesor parietal relativo (EPR. En este trabajo, los autores presentan la técnica ecocardiográfica para la evaluación del EPR en el perro y su valor normal promedio. Los resultados obtenidos fueron los siguientes: Media: 0,482; Desviación estándar: 0,098; Coeficiente de variación: 18,37%; Valor mínimo: 0,355; Primer cuartil: 0,407; Mediana: 0,459; Tercer cuartil: 0,528; Valor máximo: 0,728.

One of the mechanisms that is always present in cardiac adaptation is hypertrophy of myocardium. The degree of hypertrophy can be evaluated measuring the left ventricular myocardial mass. Nevertheless this parameter measures the amount of hypertrophy, but not how it is distributed; this can be evaluated by means of relative wall thickness (RWT index. In the present study the authors describe the echocardiography technique for the evaluation of the RWT in the dog and present its normal mean value.

    The correct and early identification of humans and dogs infected with Leishmania are key steps in the control of leishmaniasis. Additionally, a method with high sensitivity and specificity at low cost that allows the screening of a large number of samples would be extremely valuable. In this study, we analyzed the potential of mitogen-activated protein kinase 3 (MAPK3) and mitogen-activated protein kinase 4 (MAPK4) proteins from Leishmania braziliensis to serve as antigen candidates for the serodiagnosis of human visceral and tegumentary leishmaniasis, as well as canine visceral disease. Moreover, we mapped linear B-cell epitopes in these proteins and selected those epitopes with sequences that were divergent in the corresponding orthologs in Homo sapiens, in Canis familiaris, and in Trypanosoma cruzi. We compared the performance of these peptides with the recombinant protein using ELISA. Both MAPK3 and MAPK4 recombinant proteins showed better specificity in the immunodiagnosis of human and canine leishmaniasis than soluble parasite antigens and the EIE-leishmaniose-visceral-canina-bio-manguinhos (EIE-LVC) kit. Furthermore, the performance of this serodiagnosis assay was improved using synthetic peptides corresponding to B-cell epitopes derived from both proteins.

  20. Wolves (Canis lupus) and dogs (Canis familiaris) differ in following human gaze into distant space but respond similar to their packmates' gaze.

    Gaze following into distant space is defined as visual co-orientation with another individual's head direction allowing the gaze follower to gain information on its environment. Human and nonhuman animals share this basic gaze following behavior, suggested to rely on a simple reflexive mechanism and believed to be an important prerequisite for complex forms of social cognition. Pet dogs differ from other species in that they follow only communicative human gaze clearly addressed to them. However, in an earlier experiment we showed that wolves follow human gaze into distant space. Here we set out to investigate whether domestication has affected gaze following in dogs by comparing pack-living dogs and wolves raised and kept under the same conditions. In Study 1 we found that in contrast to the wolves, these dogs did not follow minimally communicative human gaze into distant space in the same test paradigm. In the observational Study 2 we found that pack-living dogs and wolves, similarly vigilant to environmental stimuli, follow the spontaneous gaze of their conspecifics similarly often. Our findings suggest that domestication did not affect the gaze following ability of dogs itself. The results raise hypotheses about which other dog skills might have been altered through domestication that may have influenced their performance in Study 1. Because following human gaze in dogs might be influenced by special evolutionary as well as developmental adaptations to interactions with humans, we suggest that comparing dogs to other animal species might be more informative when done in intraspecific social contexts.

    Dogs are able to solve different problems by trial and error learning, but it seems that they cannot understand the means-end connection. Some studies suggest that dogs' performance is influenced by their breed and by the level of familiarity with the person they interact with. In our study, we assess individual differences in both social and non-social responses in a problem-solving task during the acquisition, extinction, and reacquisition phases. In order to investigate the effect of familiarity, in the first experiment, the human present during the task was either a familiar (the dog's owner) or unfamiliar person. In the second experiment, we compared breeds (Retrievers and Shepherds) that had previously shown differences in a communicative task. The results revealed that all groups learned the task and became more efficient in the acquisition trials. These non-social responses diminished during extinction, where an increase in social responses was observed. With regard to individual differences, dogs were more persistent in searching the reward during the second extinction trial when the owner was present (in contrast with a stranger), and also looked longer at the unfamiliar person at the beginning of the acquisition trial. On the other hand, Retrievers showed greater social motivation during reacquisition and Shepherds picked up more bones during the third acquisition trial, thus suggesting a more persistent search of the reward. These findings highlight the relevance of studying different learning schedules as well as individual differences in problem-solving ability so as to improve selection and training techniques.

    The nature of the interactions that maintain the social behavior of dogs toward humans and which interactions dogs prefer have not been thoroughly investigated. We focused here on dogs' preference for petting and vocal praise, and the influence that familiarity (owner vs. stranger) has on that preference. We first used concurrent choice to evaluate dogs' preference for petting or vocal praise and measured the initial choice, the time spent with each alternative, and the number of within-session alternations. We assessed dogs' preference for petting or vocal praise in (1) shelter dogs, (2) owned dogs with strangers providing both interactions, and (3) owned dogs with the dog's owner providing the interactions. Across all experimental groups, dogs preferred petting to vocal praise. We next assessed time spent with each alternative when only one alternative was available at a time in shelter dogs and owned dogs (Experiment 2). Shelter dogs were tested with a stranger and owned dogs were tested with their owners providing the interaction. Dogs alternated between petting and vocal praise, vocal praise and no interaction, or received only petting for eight 3-min sessions of each comparison. Both shelter and owned dogs spent significantly longer in proximity to the experimenter when the interaction was petting compared to vocal praise. Vocal praise produced as little proximity-seeking behavior as did no interaction. Additionally, dogs did not show any sign of satiation with petting across all eight sessions. Overall, petting seems to be an important interaction between dogs and humans that might maintain inter-specific social behavior but vocal praise likely has to be specifically conditioned.

    The major whey proteins of the milks of the dolphin, manatee, and beagle were purified by gel filtration and ion exchange chromatography and characterized and identified by molecular weight determination, amino acid analysis, N-terminal sequencing, and activity measurements. The major whey protein components from all three species were found to be monomeric beta-lactoglobulins. These proteins were all active in binding retinol. Dolphin milk contained two beta-lactoglobulins (designated 1 and 2) which showed a slight difference in molecular weight and considerably divergent N-terminal sequences, whereas the other milks only contained a single form of beta-lactoglobulin. alpha-Lactalbumins were purified from dolphin and dog milks and were active in promoting lactose synthesis by bovine galactosyltransferase. The dolphin protein had an N-terminal sequence more similar to ruminant alpha-lactalbumins than to those known from other species. Although alpha-lactalbumin activity has been detected in manatee milk at low levels, the corresponding protein was not isolated. In addition, dog milk was found to contain high levels of lysozyme (greater than 1.0 mg/ml), which were identified by activity and sequencing. The functional and evolutionary implications of these results are discussed. PMID:3707136

    Domestic dogs have been recognized for their social sensitivity and aptitude in human-guided tasks. For example, prior studies have demonstrated that dogs look to humans when confronted with an unsolvable task; an action often interpreted as soliciting necessary help. Conversely, wolves persist on such tasks. While dogs' 'looking back' behaviour has been used as an example of socio-cognitive advancement, an alternative explanation is that pet dogs show less persistence on independent tasks more generally. In this study, pet dogs, shelter dogs and wolves were given up to three opportunities to open a solvable puzzle box: when subjects were with a neutral human caretaker, alone and when encouraged by the human. Wolves were more persistent and more successful on this task than dogs, with 80% average success rate for wolves versus a 5% average success rate for dogs in both the human-in and alone conditions. Dogs showed increased contact with the puzzle box during the encouragement condition, but only a moderate increase in problem-solving success. Social sensitivity appears to play an important role in pet and shelter dogs' willingness to engage in problem-solving behaviour, which could suggest generalized dependence on, or deference to, human action.

All international and national studies on this subject have contributed to uncovering part of it, shedding light on a very serious and dramatic reality. For that reason, in April 2001, the Italian Parliament passed the law n. 154 concerning “Measures against domestic violence”, therefore affirming in by this act its will to respond to the problem. The law, which is considered an example of a “normative act against the blackmail of fear”, consists of a series of guide lines to prevent the offender from repeating the crime. In view of this, it is essential to find out today what has actually changed in Italy six years after its coming into force. La violence intrafamiliale est un délit. Les études réalisées à l'échelle internationale, tout comme les études nationales, ont ouvert une brèche sur cette réalité dont la gravité est déconcertante. Cependant le Parlement italien a approuvé en avril 2001, la loi relative aux "Mesures contre la violence dans la famille", affirmant ainsi sa volonté de répondre concrètement au problème de la violence domestique en Italie. Cette loi, présentée par les législateurs comme un example "d'acte normatif contre le chantage de la peur", contient une série de provisions destinées à empêcher à l'offenseur de réitérer son crime, introduisant des instruments procéduraux contre les abus intrafamiliaux. Face à de telles innovations, il est d'autant plus utile de continuer à se demander ce qui a changé en Italie, six ans après l'entrée en viguer de la loi.

    Full Text Available Foi realizado um estudo comparativo da reação de imunofluorescência indireta em eluatos de sangue de cães infectados experimentalmente com diferentes tripanosomatídeos. Utilizaram-se como antigenopromastigotas de L. mexicana, L. braziliensis e L. chagasi. Os resultados mostraram que a sensibilidade do método foi de 87,5% para o diagnóstico do calazar canino, independentemente do antigeno empregado; e que ocorre reação cruzada com Leishmaniose tegumentar em 75% dos casos e com doença de Chagas em 83,3%. Levantamento epidemiológico em área de leishmaniose confirma que a reação de imunofluorescência em eluatos de sangue canino fornece reações cruzadas em cães infectados com Leishmania braziliensis e L. chagasi. Não se verificou reação cruzada pela RFC. Sugere-se a utilização da reação de imunofluorescência nas campanhas de saúde pública, mas é de se chamar a atenção para o fato de que as taxas de positividade não devem ser utilizadas como indicadores da prevalência do calazar canino.A comparative study was made of eluates of the blood of dogs experimentally infected with different trypanosomatids. Using antigens prepared from promastigotes of Leishmania mexicana, L. braziliensis and L. chagasi, assessments were made by the indirect immunofluorescence test. The results showed a sensitivity of 87,5% in the diagnosis of canine visceral leishmaniasis, independent of antigen used. Cross-reactions occurred in 75% of cases of cutaneous leishmaniasis and 83,3% of dogs with chagas' disease. An epidemiological survey in an area of leishmaniasis confirmed that immunofluorescence tests on eluates of dogs' blood give cross-reactions between L. braziliensis and L. chagasi. The results suggest that such testing could be useful in public health campaigns but attention is drawn to thefact that the level ofpositive reactions cannot be used as an indicator of the prevalence of canine kala-azar.

    Two new commercially available high linolenic oils, pressed at low temperature from rose hip seeds, were characterised for their composition, quality and DPPH radical scavenging activity. The oxidative stability of oils was assessed using differential scanning calorimetry (DSC). Phytosterols, tocopherols and carotenoids contents were up to 6485.4; 1124.7; and 107.7 mg/kg, respectively. Phenolic compounds determined for the first time in rose hip oil totalled up to 783.55 μg/kg, with a predominant presence of p-coumaric acid methyl ester. Antiradical activity of the oils reached up to 3.00 mM/kg TEAC. The acid, peroxide and p-anisidine values as well as iron and copper contents indicated good quality of the oils. Relatively high protection against oxidative stress in the oils seemed to be a result of their high antioxidant capacity and the level of unsaturation of fatty acids. PMID:26041218

    Full Text Available The efficacy of keto acids and essential amino acids on a two-year-old female dog, Labrador, suffering from Leishmaniasis and acute renal failure was evaluated by clinical and laboratorial analyses based on urea and creatinine dosages. An improving in the animal general condition and an increasing in the appetite, activity and weight gain, were observed and favorably contributed to the treatment of the primary disease. Ketoanalogueswere oraly administered during 76 days and the levels of urea and creatinine remained within acceptable limits, even after this period of time. Ketoanaloguescontributed positively for the treatment of acute renal failure and appears to be an important alternative for the leishmaniasis treatment.

Los casos se eligieron en función del diagnóstico clínico, endoscópico y anatomopatológico realizado, con el objetivo de evaluar potenciales correlaciones entre estos parámetros. La disminución de proteínas totales y la albúmina no fue estadísticamente significativa en relación con el grado de inflamación de la mucosa gastrointestinal, no obstante, los animales que presentaban un infiltrado de tipo linfoplasmocitario tenían tendencia a la pérdida de albúmina. Se encontró una correlación estadísticamente significativa (P < 0,05 entre el tipo de infiltrado y la presencia de congestión en la mucosa de estómago y duodeno. Una mayor congestión a estos niveles se corresponde con el infiltrado linfoplasmocitario. También se obtuvo un resultado que, a pesar de no ser estadísticamente significativo, sí se aproxima a la significación estadística (P < 0,1 entre el grado de congestión y la intensidad del infiltrado, ya que un grado de congestión mayor de la mucosa se corresponde con una mayor intensidad de infiltrado linfoplasmocitario, tanto a nivel gástrico como duodenal. Además se vio que la friabilidad está asociada a inflamación en duodeno, y los animales que no tenían un correcto cierre del cardias presentaban esofagitis por reflujo.

    This pilot surveillance included 152 patients with acute exacerbations of chronic pain, 124 (Back group) with non-specific low back pain (NSLBP), 20 with NSLBP overridden by osteoarthritic pain (Knee-Hip group), and eight with specific LBP (included in the safety analysis). Patients were recommended the rose hip and seed powder Litozin at a dose providing up to 3 mg of galactolipid/day for up to 54 weeks. Clinical symptoms and well-being were assessed every 6 weeks. The patients also kept a diary of their pain and the requirement for rescue medication. Data were analysed by intention to treat with last observation carried forward. Only 77 patients completed the year of surveillance. Multivariate analysis suggested an appreciable overall improvement during the surveillance, irrespective of group, and this was reflected for most of the individual measures in repeated measures ANOVA. The degree and time-course of improvement echoed that seen in similar surveillances of patients receiving an aqueous extract of Harpagophytum. Multiple regression analyses indicated that percentage changes from baseline tended to be greater in patients with greater degrees of pain and disability, but were otherwise largely unrelated to the patients' characteristics. There were no serious adverse events. The rose hip and seed powder, Litozin, seems to deserve further, more definitive studies as a possible option in long-term management of NSLBP with or without osteoarthritic pain. PMID:18729248

    Full Text Available A incontinência urinária adquirida é uma condição debilitante e, muitas vezes, incurável que acomete fêmeas castradas e raramente fêmeas inteiras ou machos. A manifestação clínica pode ocorrer em qualquer momento após a gonadectomia e resulta em graves problemas no manejo do paciente. Os mecanismos que desencadeiam a incontinência após ovariectomia envolvem decréscimo na pressão de fechamento uretral, alterações hormonais, aumento na deposição de colágeno na musculatura lisa da bexiga, diminuição na contratilidade do músculo detrusor e redução na resposta aos estímulos elétricos e ao carbachol. O diagnóstico é realizado pelo histórico do animal, pelo exame físico, pelos exames laboratoriais, pelo perfil de pressão uretral, pela ultrassonografia e pelas radiografias abdominais. O tratamento clínico envolve utilização de fármacos -adrenérgicos, estrógenos, análogos de GnRH e agentes antidepressivos. As técnicas cirúrgicas recomendadas correspondem à uretropexia, cistouretropexia, aplicação de colágeno na uretra e colpossuspensão. Melhor compreensão da etiologia, da fisiopatologia, dos métodos de diagnóstico e tratamentos é fundamental em razão do pouco conhecimento e da identificação dessa condição no Brasil.Acquired urinary incontinence is a debilitating, incurable condition, prevalent in spayed bitches and rarely seen in entire bitches or males. In bitches, acquired urinary incontinence can occur anytime from one week after neutering and is associated with severe management problems. Incontinence in neutered bitches can be associated with a decrease in maximal urethral closure pressure, hormonal changes and increase in the percentage of collagen in the bladder wall. It's also associated to a reduced contractility of the detrusor muscle, decrease in the magnitude of response of the bladder wall to both carbachol and eletrical field stimulation, and there are risk factors involved. The diagnosis is established based on historical findings, physical examination, laboratorial exams, urethral pressure profilometry, ultrasonography and abdominal radiographs. The medical management involves the appliance of -adrenergics agonists, oestrogens, GnRH analogues and antidepressive agents. Surgical recommendation management corresponds to urethropexy, cistourethropexy, endoscopic periurethral injection and colposuspension. The better understanding A better comprehension of etiology, physiopathology, diagnosis methods and treatment could provide significant benefits considering the lack of knowledge and diagnoses of this clinical condition in Brazil.

The study was applied at 22 adult dogs, 11 males and 11 females. Previously, the DAC and H of all animals were measured. For ultrasonographic examination, the ultra-sound system HDI 4000 PHILIPS equipped with a multi-frequency microconvex transducer, Color Doppler and Spectral Doppler devices was used. The animals were placed into right or left lateral decubitus position, in agreement with the kidney to be assessed. The longitudinal (LD and dorsoventral diameters (DVD of kidney were measured in longitudinal plane, and the transverse diameter (TD was determined in transversal section. The renal volume (V was automatically calculated by the ultrasound software. With Triplex Doppler, the RI and PI of right and left main renal arteries were obtained. All data were represented in mean ± SEM. Linear regression analyses were performed with renal LD, DVD, TD and V as dependent variable, and ACD and H as independent variable. RI and PI were compared between right and left renal arteries with Student's t-test. The LD, DVD, TD (cm and V (ml mean measurements for the left and right kidneys were: 5.24±0.27, 3.07±0.15, 3.07±0.9, 28.01±3.4 and 4.50±0.19, 2.88±0.14, 2.71±0.15, 21.27±2.6.

    Full Text Available Utilizou-se ultra-sonografia bidimensional em tempo real na avaliação de 20 bulbos oculares de 10 cães, sem alterações clínicas visíveis, e de 55 bulbos oculares de 30 cães com opacificação de meios transparentes. Empregou-se transdutor mecânico setorial de 7,5 MHz com almofada de recuo, em técnica de contato corneano. Para a realização dos exames, os animais foram contidos mecanicamente e as córneas receberam anestesia tópica. A blefarostasia deu-se manualmente. Os bulbos foram avaliados com o transdutor aplicado nas posições vertical e horizontal. As características ultra-sonográficas encontradas em olhos normais o foram a similitude da literatura especializada. Relativamente aos bulbos oculares com opacificação de meios transparentes, encontraram-se alterações junto às estruturas e compartimentos. Destacaram-se as cataratas, as luxações e subluxações do cristalino, as degenerações do vítreo, as hemorragias e inflamações em câmaras anterior e vítrea e os descolamentos de retina. A base dos achados e a fidedignidade das imagens colhidas permitem admitir que a ultra-sonografia bidimensional em tempo real, utilizando o transdutor mecânico setorial de 7,5MHz com almofada de recuo, adequa-se ao exame das estruturas intra-oculares, mormente na Medicina Veterinária em que os recursos são parcos à aplicação de procedimentos mais sofisticados ou de equipamentos para ultra-sonografia próprios à especialidade.The two-dimensional real-time ultrasonography was used to evaluate 20 normal eyes of 10 dogs and 55 eyes o f 30 dogs with ocular opacity. A 7.5MHz mechanical sector fluid offset transducer was utilized, and the corneal contact method was performed. The exams were carried out with the animal awake, the córnea received a topical ophtalmic anesthetic, and the eyelids were held open manually. The eyes were examined with the transducer in vertical and horizontal positions. The ultraso- nographic characteristics found in the normal eye structures were compatible with the experiences related by several dijferent authors. Several changes were found in the structures and chambers of the eye which presented opacities of the media, such as cataracts, lens luxation and sub-luxation, vitreous degeneration, hemorrhage and inflammation in the vitreal chamber, besides retinal detachments. On the basis of the studies carried out and the obtained results, it was possible to conclude that the two-dimensional real-time ultrasonography, with the use of a 7.5MHz mechanical sector fluid offset transducer shows a satisfactory adaptability to the evaluation of the intra-ocular structures. It is indicated specially in Veterinary Medicine in which resources are scanty to sophisticated procedures or specific eye ultrasound equipment.

Dos animais com suspeita clínica e epidemiológica de LV, foi coletada amostra de sangue para realização de hemograma, provas bioquímicas, sorologia, cultura do parasito, PCR e RAPD. Os cães portadores de quadro clínico, como febre, hiperqueratose, onicogrifose e emagrecimento exagerado, tiveram gânglio poplíteo e/ou medula óssea puncionados e o conteúdo inoculado em meio de cultivo NNN. A extração de DNA do parasito em sangue e cultura foi realizada pelo método fenol/clorofórmio. A amplificação de DNA do protozoário foi feita por PCR e RAPD. Dos 24 animais analisados, o parasito foi isolado em 19 cães. As técnicas moleculares permitiram identificar 14 isolados como L. (Leihmania infantum e cinco como L. (Viannia braziliensis. A análise epidemiológica dos casos permitiu determinar o local de transmissão e definir que todos os cães com LV diagnosticados eram casos alóctones, ou seja eram importados de regiões endêmicas. Sugere-se que a migração dos cães de regiões endêmicas para regiões indenes poderá permitir a instalação de novos focos, desde que o agente encontre ecótopo adequado e vetor específico (Lutzomyia longipalpis.The south region is the only area in Brazil that does not present autochthonous cases of visceral leishmaniasis (VL, however, in the state of Parana, dogs and humans have been found showing a VL compatible clinical profile.

The diagnosis of the disease was based on direct observation of amastigotes of Leishmania spp., in popliteal lymph nodes, suggesting that a case of VL, since the animal came from an endemic area for the disease. The migration of infected dogs from endemic regions to areas unaffected becomes a problem for public health, since it may allow the installation of new outbreaks by encouraging the spread of disease throughout the country.O presente relato tem por objetivo descrever o primeiro caso alóctone de leishmaniose visceral (LV no município de Campo Mourão, Paraná, Brasil, em um canino, da raça Boxer, apresentando lesões oculares e cutâneas, linfoadenomegalia e esplenomegalia, atendido no Hospital Veterinário da Faculdade Integrado de Campo Mourão, após ter residido na cidade de Campo Grande, Mato Grosso do Sul. O diagnóstico da enfermidade baseou-se na observação direta de formas amastigotas de Leishmania spp., em linfonodos poplíteos, sugerindo ser um caso de LV, uma vez que o animal era proveniente de área endêmica para a enfermidade. A migração de cães infectados de regiões endêmicas para áreas indenes torna-se um problema para a saúde pública, uma vez que poderá permitir a instalação de novos focos, favorecendo a disseminação da doença em todo o país.

Leucócitos de uma cadela experimentalmente infectada com o isolado Jaboticabal de E. canis foram inoculados em cultivo de células DH82. A inoculação foi monitorada após a segunda semana, a cada 5-6 dias, através de exames citológicos e pela amplificação de um fragmento do gene dsb de Ehrlichia pela Reação em Cadeia pela Polimerase (PCR para confirmação da infecção. A cultura apresentou-se positiva aos 27 dias pós-inoculação pela PCR e aos 28 dias pela citologia. No 33o dia pós-inoculação, observou-se 20% de células infectadas e, aos 53 dias, 60% de infecção. Atualmente, o isolado encontra-se estabelecido em células DH82, com várias passagens atingindo 90-100% de células infectadas entre 7-10 dias após a inoculação. Após o seqüenciamento do produto de PCR, o isolado apresentou-se 100% similar à seqüência correspondente de E. canis depositada no GenBank. As células infectadas foram utilizadas como antígeno para a padronização da RIFI para detecção da infecção em cães.The present study describes a successful isolation of Ehrlichia canis and its establishment in DH82 cells, followed by the development of an Indirect Fluorescent Antibodies Test (IFAT. Leukocytes collected from an experimentally infected dog with the Jaboticabal strain of E. canis were used to inoculate a DH82 cell monolayer. Two weeks later, the inoculated culture was checked for infectivity, every 5-6 days by both cytological staining and PCR, targeting a fragment of the dsb gene. The cell culture showed to be infected by Ehrlichia on day 27 by PCR and on day 28 by cytological staining. By the day 33, the infection rate reached 20% and on day 53, 60%. Currently, the isolate is established in DH82 cells, with several passages reaching 90-100% of infected cells, within 7 to 10 days post inoculation. After sequencing, the amplicon was identical to other E. canis corresponding sequences available in the GenBank. DH82 infected cells were used to standardize an IFAT for the diagnosis of canine ehrlichiosis.

Os graus de claudicação e dor apresentaram decréscimo significativo ao longo do período avaliado em ambos os grupos, sem apresentarem diferenças quando comparados entre si. Com relação à perimetria da coxa, flexão, extensão e amplitude de movimento articular, foi observado o aumento dos valores numéricos destas variáveis ao longo do estudo. Baseado nos achados, concluiu-se que a abordagem percutânea ou aberta na DC produz similitude nas variáveis avaliadas, e ambas trazem bons resultados.Joint capsule denervation is based on removal of sensitive fibers from the acetabular edge and has been used as one of the techniques to joint pain relief in the canine dysplastic hip. This study compared the techniques of percutaneous and open hip denervation in 25 dogs that showed clinical and radiographic signs of hip dysplasia, totaling 31 surgeries. The effects of the techniques were evaluated and compared in a period of 180 days following surgery, including subjective evaluation of lameness and pain, thigh girth, maximum degree of hip flexion and extension and range of motion (ROM. Degree of lameness and pain significantly decreased during the study period for both groups, and no difference could be observed between groups. Thigh girth, degree of flexion, extension and ROM presented an increase in the numerical values throughout the study. Based on these findings, it is concluded that the percutaneous or open approach for capsular denervation produced similar results.

    Full Text Available The thymic morphometry analysis was used for determining apoptosis and atrophy of the thymus of eight puppies inoculated with canine distemper virus (CDV. Three healthy dogs were used as negative controls. Sections, 5µm thick, were stained by HE and Shorr, and the latter were evaluated by morphometry. CDV nucleoprotein was detected by immunohistochemistry. Morphometric results confirmed lymphoid hypotrophy in CDV inoculated dog thymuses, more stroma, less parenchyma and higher apoptotic index/field than negative control (not inoculated puppies. Apoptosis plays a role in the mechanism of thymus atrophy that develops in canine distemper.Determinaram-se a apoptose e a atrofia no timo de oito cães novos, inoculados experimentalmente com o vírus de cinomose. Três cães saudáveis foram usados como controle negativo. Secções coradas pelo Shorr foram avaliadas por morfometria. A nucleoproteína viral foi detectada por imunoistoquímica. Os resultados morfométricos confirmaram a hipotrofia e mostraram que o timo dos cães inoculados tinha mais estroma, menos parênquima e maior índice apoptótico/campo que o dos animais-controle. Pode-se concluir que a apoptose desempenha importante papel no mecanismo de hipotrofia tímica que se desenvolve na cinomose.

Para esto se procedió a la extracción quirúrgica de fascia lata de caninos mayores de 15 kg, que posteriormente fue conservada en glicerina al 75%. Se seleccionaron siete pacientes caninos machos con hernia perineal unilateral. Los animales fueron sometidos a cirugía mediante un abordaje perineal, reduciendo la hernia, reposicionando los músculos y utilizando la fascia lata alogénica como material de reconstrucción del diafragma pélvico fijada a puntos simples con nylon monofilamento Nº 0. Se realizaron controles a los 7, 15, 30 y 60 días postcirugía, evaluando los siguientes parámetros: defecación, inflamación local y dolor. El injerto alogénico fue compatible en todos los casos tratados, lográndose una herniorrafia exitosa, sin complicaciones posoperatorias a los 60 días. En todos los casos la defecación, micción y anatomía regional volvieron a la normalidad. Este material demostró ser biocompatible y muy bien tolerado, permitiéndonos disponer de una opción segura para la técnica de herniorrafia perineal en el perro.The aim of this study was to describe and evaluate the treatment of perineal herniorrhaphy in dogs using allogeneic fascia lata. For this purpose, fascia lata was obtained from dog weighing 15 kg or more, whose death cause did not involve infectious or oncologic conditions, nor collagen- disease or trauma, or surgical scars to the thighs. The fascia lata was preserved in 75% glycerin solution. Seven patients with unilateral perineal hernia were selected for this clinical trial. Using a perineal approach, the hernia was reduced, muscles repositioned, and reconstruction was achieved suturing the fascia lata with interrupted 0 Nylon monofilament suture. Evaluations were made at 7, 15, 30 and 60 days, to assess the following parameters: defecation, micturition, local inflammation, and pain. The allogeneic graft was not rejected, and the herniorrhaphy technique was successful in all cases. No post-surgical complications were observed at 60 days after, while defecation, micturition and regional anatomy returned to normality. Allogeneic processed fascia lata has herein demonstrated to be biocompatible and well tolerated, thus allowing to be considered a safe and useful option to perineal herniorrhaphy technique in dogs.

    Full Text Available The aim of this paper is to report the occurrence of apoptosis in peripheral blood leukocytes and in syncytia induced by experimental infection of dogs with canine distemper virus. Blood was collected from nine puppies that were inoculated with the Snyder Hill strain of CDV, and stained with May Grunwaldt-Giemsa. Dogs were necropsied and retropharyngeal lymph nodes were collected and processed for paraffin embedding. Five micrometers thick sections were stained with hematoxylin-eosin and methyl green pyronin. Other sections were submitted to TUNEL reaction for in situ detection of apoptosis, and immunohistochemistry to detect CDV antigen. Immunohistochemistry confirmed the presence of viral antigen. Syncytia were present in all retropharyngeal lymph nodes. Several syncytia contained apoptotic nuclei as detected by hematoxylin-eosin and methyl green pyronin stains. Apoptotic nuclei were labeled inside syncytia by the TUNEL reaction. Blood smear analyses indicated higher proportion of apoptotic leukocytes in the peripheral blood of infected dogs.

    Full Text Available The authors describe their experience with an automated immunohistochemical system applied to canine tissue samples. Twenty human cellular markers specific monoclonal and polyclonal antibodies and two different antigen retrieval methods were used in normal and neoplastic breast tissue, as well as skin samples obtained from female dogs of pure and mixed breeds. The antibodies tested were the most frequently used in human and veterinary medicine studies, employed with diagnostic purposes in breast pathology, as well as in cancer research. Most of them may be used to study other normal and abnormal tissues and included cytokeratins, progesterone receptor, c-erbB2, p53, MIB-1, PCNA, EMA, vimentin, desmin, alpha-actin, S-100, pan-cadherin, and E-cadherin. The results demonstrated that using an automated staining system it is possible to use different human markers in veterinary pathology. The advantages of automated immunohistochemistry are improved quality, reproducibility, speed, and standardisation.Os autores descrevem sua experiência com um sistema automático de imunoistoquímica aplicada à amostras de tecido canino. Foram utilizados 20 anticorpos humanos monoclonais e policlonais e dois diferentes métodos de recuperação antigênica em tecido mamário normal e neoplásico, bem como em amostras de pele obtidas de cadelas. Os anticorpos testados estão entre os mais usados em estudos de medicina humana e veterinária, com finalidade de diagnóstico em patologia mamária, bem como na pesquisa do câncer. Muitos deles podem ser usados para estudar outros tecidos normais e com alterações e incluem citoqueratinas, receptor de progesterona, c-erbB2, p53, MIB-1, PCNA, EMA, vimentina, desmina, alfa-actina, S-100, pan-caderina e E-caderina. Os resultados demonstraram que usando um sistema automático de imunoistoquímica é possível usar diferentes marcadores humanos em patologia veterinária. As vantagens da imunoistoquímica automatizada são melhora da qualidade, reprodutibilidade, rapidez e padronização.

  20. Edge detection techniques for iris recognition system

    International Nuclear Information System (INIS)

    Nowadays security and authentication are the major parts of our daily life. Iris is one of the most reliable organ or part of human body which can be used for identification and authentication purpose. To develop an iris authentication algorithm for personal identification, this paper examines two edge detection techniques for iris recognition system. Between the Sobel and the Canny edge detection techniques, the experimental result shows that the Canny's technique has better ability to detect points in a digital image where image gray level changes even at slow rate
