    Since June 2013 the total feed ban of processed animal proteins (PAPs) was partially lifted. Now it is possible to mix fish feed with PAPs from non-ruminants (pig and poultry). To guarantee that fish feed, which contains non-ruminant PAPs, is free of ruminant PAPs, it has to be analysed with a ruminant PCR assay to comply with the total ban of feeding PAPs from ruminants. However, PCR analysis cannot distinguish between ruminant DNA, which originates from proteins such as muscle and bones, and ruminant DNA, which comes from feed materials of animal origin such as milk products or fat. Thus, there is the risk of obtaining positive ruminant PCR signals based on these materials. The paper describes the development of the combination of two analysis methods, micro-dissection and PCR, to eliminate the problem of 'false-positive' PCR signals. With micro-dissection, single particles can be isolated and subsequently analysed with PCR.

    Full Text Available The increase in world fuel prices in the last few years has charged the global animal feedstuffs. In Malaysia, the feed industry is dependent on the importation of corn and soybean meal as the poultry and swine industries are almost totally based on corn soya bean meal diets. However, there are many byproducts and coproducts available in Malaysia as alternatives to corn or soy bean. Since Malaysia has more than 4 million hectares of oil palm plantation and after processing for the oil, large quantities of several byproducts are produced. This paper describes several available byproducts and co products in Malaysia, their nutritive value and their problems.

    The radionuclides of most concern with respect to contamination of animals after a nuclear accident are radioiodine, radiocaesium and radiostrontium (ICRP 30, 1979). Of the other significant anthropogenic radionuclides likely to be released in most accidents, only small proportions of that ingested will be absorbed in an animals gut, and the main animal products, milk and meat, will not normally be contaminated to a significant extent. Animal products will mostly be contaminated as a result of ingestion of contaminated feed and possibly, but to a much lesser extent, from inhalation (for radioiodine only). Direct external contamination of animals is of little or no consequence in human food production. Radioiodine and radiostrontium are important with respect to contamination of milk; radiocaesium contaminates both milk and meat. The physical and chemical form of a radionuclide can influence its absorption in the animal gut. For example, following the Chernobyl accident radiocaesium incorporated into vegetation by root uptake was more readily absorbed than that associated with the original deposit. The transfer of radiocaesium and radiostrontium to animals will be presented both as transfer coefficients and aggregated transfer coefficients. For most animal meat products, only radiocaesium is important as other radionuclides do not significantly contaminate muscle. Farm animal products are the most important foodstuff determining radiocaesium intake by the average consumer in the Nordic countries. The major potential source of radioiodine and radiostrontium to humans is milk and milk products. Of the different species, the smaller animals have the highest transfer of radiocaesium from fodder to meat and milk. (EG). 68 refs.

    This study assesses the suitability of vegetable waste produced by food industry for use as a raw material for animal feed. It includes safety and nutritional viability, technical feasibility and environmental evaluation. Vegetable by-products were found to be nutritionally and sanitarily appropriate for use in animal feed. The drying technologies tested for making vegetable waste suitable for use in the animal feed market were pulse combustion drying, oven and microwave. The different meal prototypes obtained were found to comply with all the requirements of the animal feed market. An action plan that takes into account all the stages of the valorisation process was subsequently defined in agreement with local stakeholders. This plan was validated in a pilot-scale demonstration trial. Finally, the technical feasibility was studied and environmental improvement was performed. This project was funded by the European LIFE+ program (LIFE09 ENV/ES/000473).

    2016-05-01

    Animal hairs consisting of α-keratin biopolymers existing broadly in nature may be responsive to water for recovery to the innate shape from their fixed deformation, thus possess smart behavior, namely shape memory effect (SME). In this article, three typical animal hair fibers were first time investigated for their water-stimulated SME, and therefrom to identify the corresponding net-points and switches in their molecular and morphological structures. Experimentally, the SME manifested a good stability of high shape fixation ratio and reasonable recovery rate after many cycles of deformation programming under water stimulation. The effects of hydration on hair lateral size, recovery kinetics, dynamic mechanical behaviors and structural components (crystal, disulfide and hydrogen bonds) were then systematically studied. SME mechanisms were explored based on the variations of structural components in molecular assemblies of such smart fibers. A hybrid structural network model with single-switch and twin-net-points was thereafter proposed to interpret the water-stimulated shape memory mechanism of animal hairs. This original work is expected to provide inspiration for exploring other natural materials to reveal their smart functions and natural laws in animals including human as well as making more remarkable synthetic smart materials.

    Titanium rods were processed into implant samples with cavity and groove in which was filled with HAP/β-TCP porous osteoconduction composite materials in order to increase the mechanical stability of the implant in vivo. The phase compositions of the composite was characterized by X-ray diffraction (XRD) and scanning electron microscopy(SEM). Histological evaluation showed that the biogradable composite could enhanced the ability of new bone formation. The composite can conduct new bone tissue growing into the cavities gradually after implanted into animal, and then achieve mechanical fixation. The filling biogradable compound exhibited excellent biocompatibility, which combined with the new bone tissues tightly without inflammation and loosing.

    Unique in vivo tests were conducted through the use of a fistulated ruminant, providing an ideal environment with a diverse and vibrant microbial community. Utilizing such a procedure can be especially invaluable for investigating the performance of antimicrobial materials related to human and animal related infections. In this pilot study, it is shown that the rumen of a fistulated animal provides an excellent live laboratory for assessing the properties of antimicrobial materials. We investigate microbial colonization onto model nanocomposites based on silver (Ag) nanoparticles at different concentrations into polydimethylsiloxane (PDMS). With implantable devices posing a major risk for hospital-acquired infections, the present study provides a viable solution to understand microbial colonization with the potential to reduce the incidence of infection through the introduction of Ag nanoparticles at the optimum concentrations. In vitro measurements were also conducted to show the validity of the approach. An optimal loading of 0.25 wt% Ag is found to show the greatest antimicrobial activity and observed through the in vivo tests to reduce the microbial diversity colonizing the surface. PMID:26098413

    This research program performed by Ceramatec may significantly increase the beneficial utilization of fly ash, and improve the overall performance of high quality animal litter products. Ceramatec has developed a novel high surface area material, which is capable of ammonia adsorption. High surface area zeolites when combined with agglomerated fly ash can significantly reduce the use of naturally mined materials (i.e. clay bentonite) for animal litter manufacture. This not only preserves natural resources and the natural environment, but it also will reduce CO2 emissions, via the reduced need for heavy mining equipment. This novel animal litter is made with over 85% of recycled materials, thus preventing their disposition to landfills. The novel litter material is similar to traditional clay-like litters, and it is clumpable and has superior odor control properties.

    2014-01-01

    Pyrrolizidine alkaloids (PAs) are hepatotoxic metabolites produced by plants. PAs in animal feed can cause acute or chronic intoxications in animals and can be transferred to milk. An inter-laboratory comparison study among 12 laboratories, using their own methods of analysis, was conducted for the detection and quantification of PAs in animal feed. The participants were asked to quantify PAs in a blank test sample, a blank test sample to be spiked with a provided spiking mixture of seven PA standards, and a test sample contaminated with common groundsel (Senecio vulgaris). Ten of the participating laboratories used an LC-MS/MS method, one used an LC-ToF-MS method, and one used a GC-MS method. None of the laboratories reported false-negative samples, while two laboratories reported false-positive results in the blank sample. z-scores were calculated for each laboratory for seven PAs in test samples B and C. z-scores varied considerably between laboratories for the concentrations of the free bases and less for the N-oxides, probably due to the lower levels of the free bases as compared with the N-oxides in the contaminated feed. Questionable or unsatisfactory results for the z-scores were obtained for 8% of the cases for the spiked sample and for 12% of the incurred sample. Three laboratories scored consequently positive or negative results. No preferred method for quantification of PAs in feed could be identified within the methods used for this study due to the relatively small number of participants. It was concluded that this inter-laboratory study shows that the methods used for PA detection need further development for accurate estimation of PAs in contaminated feed.

    This study aimed to obtain insights into the presence of cadmium, lead, mercury and arsenic in feed materials and feed over time, for the purpose of guiding national monitoring. Data from the Dutch feed monitoring program and from representatives of the feed industry in the period 2007-2013 were used. Data covered the concentrations of cadmium, lead, mercury and arsenic in a variety of feed materials and compound feeds in The Netherlands. Trends in the percentage of samples that exceeded the maximum limit (ML), set by the European Commission, and trends in average, median and 90(th) percentile concentrations of each of these elements per feed material or compound feed were investigated. Based on the results, monitoring for cadmium, lead, mercury and arsenic should focus on feed material of mineral origin, feed material of marine origin, especially fish meal, seaweed and algae as well as feed additives belonging to the functional groups of (i) trace elements (notably cupric sulphate, zinc oxide and manganese oxide for arsenic) and (ii) binders and anti-caking agents. Mycotoxin binders are a new group of feed additives that also need attention. For complementary feed it is important to make a proper distinction between mineral and non-mineral feed because the ML in the latter group is usually lower. In seaweed/algae products a relatively large number of samples contained arsenic concentrations that exceeded the ML. Forage crops in general do not need high priority in monitoring programs, although for arsenic grass meal still needs attention.

    Portland cement used in the construction industry improves its properties when wet. Since most dental materials are used in a moist environment, Portland cement has been developed for use in dentistry. The first generation material is mineral trioxide aggregate (MTA), used in surgical procedures, thus in contact with blood. The aim of this study was to compare the setting of MTA in vitro and in vivo in contact with blood by subcutaneous implantation in rats. The tissue reaction to the material was also investigated. ProRoot MTA (Dentsply) was implanted in the subcutaneous tissues of Sprague-Dawley rats in opposite flanks and left in situ for 3 months. Furthermore the material was also stored in physiological solution in vitro. At the end of the incubation time, tissue histology and material characterization were performed. Surface assessment showed the formation of calcium carbonate for both environments. The bismuth was evident in the tissues thus showing heavy element contamination of the animal specimen. The tissue histology showed a chronic inflammatory cell infiltrate associated with the MTA. MTA interacts with the host tissues and causes a chronic inflammatory reaction when implanted subcutaneously. Hydration in vivo proceeds similarly to the in vitro model with some differences particularly in the bismuth oxide leaching patterns. PMID:27683067

    Attach conjunctival graft commonly used are suture technique and fibrin glue. This study was to investigate albumen glue as an alternative to suture technique in attaching conjunctival graft in rabbits. Aim of this study was to compare the conjunctival wound healing between albumen glue and suture technique in rabbit eye as a model. There was an experimental animal study included 32 eyes (16 rabbits) in PT. Bio Farma (Persero) and Histology Laboratory, Faculty of Medicine, Padjadjaran University from March 2014 to July 2104. The study consisted of albumen glue group and suture technique group. The examination included the comparison of conjunctival graft attachment and histologic examination by microscopically was done to obtain the wound gap, then analyze by Mann-Whitney test. The results indicated that the graft attachment was significantly better-using albumen glue (grade 4) compared to suture (grade 2-3) on day-1 after surgery (p=0,000). The wound gap was smaller using albumen glue (0-0,33 μm versus 5,33-14 μm ; p=0,0005) on 10 minutes after surgery and 0 μm versus 0,33-4 μm ; p=0,0005 on day-7 after surgery. In conclusion, the graft attachment using albumen glue was better and the wound gap was smaller using albumen glue than suture technique.

  1. Material balance studies on animal cell metabolism using a stoichiometrically based reaction network.

    Science.gov (United States)

    Xie, L; Wang, D I

    1996-12-05

    A detailed reaction network of mammalian cell metabolism contains hundreds of enzymatic reactions. By grouping serial reactions into single overall reactions and separating overlapped pathways into independent reactions, the total number of reactions of the network is significantly reduced. This strategy of manipulating the reaction network avoids the manipulations of a large number of reactions otherwise needed to determine the reaction extents. A stoichiometric material balance model is developed based on the stoichiometry of the simplified reaction network. Closures of material balances on glucose and each of the 20 amino acids are achieved using experimental data from three controlled fed-batch and one-batch hybridoma cultures. Results show that the critical role of essential amino acids, except glutamine, is to provide precursors for protein synthesis. The catabolism of some of the essential amino acids, particularly isoleucine and leucine, is observed when an excess amount of these amino acids is available in the culture medium. It was found that the reduction of glutamine utilization (for reducing ammonia production) is accompanied by an increase in the uptake of nonessential amino acids (NAAs) from the culture medium. This suggests that NAAs are necessary even though they are not essential for cell growth. A glutamine balance shows that less than 20% of the glutamine nitrogen is utilized for essential roles, such as protein and nucleotide syntheses. A relatively constant percentage (about 45%) of the glutamine nitrogen is utilized for NAA biosynthesis, despite the fact that the absolute amount varies among the four experiments. As to the carbon skeleton of glutamine, a significant portion enters the tricarboxylic acid (TCA) cycle. A material balance on glucose shows that most of the glucose (81%) is converted into lactate when glucose is in excess. On the other hand, when glucose is limited, lactate production is considerably reduced, while a major portion

    Rigorously standardized laboratory protocols are essential for meaningful comparison of data from multiple sites. Considering that interactions of minerals with organic matrices may vary depending on the material nature, there could be peculiar demands for each material with respect to digestion procedure. Acid digestion procedures were evaluated using different nitric to perchloric acid ratios and one- or two-step digestion to estimate the concentration of calcium, phosphorus, magnesium, and zinc in samples of carcass, bone, excreta, concentrate, forage, and feces. Six procedures were evaluated: ratio of nitric to perchloric acid at 2:1, 3:1, and 4:1 v/v in a one- or two-step digestion. There were no direct or interaction effects (p>0.01) of nitric to perchloric acid ratio or number of digestion steps on magnesium and zinc contents. Calcium and phosphorus contents presented a significant (p0.01) calcium or phosphorus contents in carcass, excreta, concentrate, forage, and feces. Number of digestion steps did not affect mineral content (p>0.01). Estimated concentration of calcium, phosphorus, magnesium, and zinc in carcass, excreta, concentrated, forage, and feces samples can be performed using digestion solution of nitric to perchloric acid 4:1 v/v in a one-step digestion. However, samples of bones demand a stronger digestion solution to analyze the mineral contents, which is represented by an increased proportion of perchloric acid, being recommended a digestion solution of nitric to perchloric acid 2:1 v/v in a one-step digestion.

    Structure-interaction/fluorescence relationship studies led to the development of a small chemical library of Zn(2+)-specific cysteamine-based molecular probes. The probe L5 with higher excitation/emission wavelengths, which absorbs in the visible region and emits in the green, was chosen as a model imaging material for biological studies. After successful imaging of intracellular zinc in four different kinds of cells including living organisms, plant, and animal cells, in vivo imaging potential of L5 was evaluated using plant systems. In vivo imaging of translocation of zinc through the stem of a small herb with a transparent stem, Peperomia pellucida, confirmed the stability of L5 inside biological systems and the suitability of L5 for real-time analysis. Similarly, fluorescence imaging of zinc in gram sprouts revealed the efficacy of the probe in the detection and localization of zinc in cereal crops. This imaging technique will help in knowing the efficiency of various techniques used for zinc enrichment of cereal crops. Computational analyses were carried out to better understand the structure, the formation of probe-Zn(2+) complexes, and the emission properties of these complexes.

    Animal models have contributed to our understanding of breast cancer, with publication of results in high-impact journals almost invariably requiring extensive in vivo experimentation. As such, many laboratories hold large collections of surplus animal material, with only a fraction being used in publications relating to the original projects. Despite being developed at considerable cost, this material is an invisible and hence an underutilised resource, which often ends up being discarded. Within the breast cancer research community there is both a need and desire to make this valuable material available for researchers. Lack of a coordinated system for visualisation and localisation of this has prevented progress. To fulfil this unmet need, we have developed a novel initiative called Sharing Experimental Animal Resources: Coordinating Holdings-Breast (SEARCHBreast) which facilitates sharing of archival tissue between researchers on a collaborative basis and, de facto will reduce overall usage of animal models in breast cancer research. A secure searchable database has been developed where researchers can find, share, or upload materials related to animal models of breast cancer, including genetic and transplant models. SEARCHBreast is a virtual compendium where the physical material remains with the original laboratory. A bioanalysis pipeline is being developed for the analysis of transcriptomics data associated with mouse models, allowing comparative study with human and cell line data. Additionally, SEARCHBreast is committed to promoting the use of humanised breast tissue models as replacement alternatives to animals. Access to this unique resource is freely available to all academic researchers following registration at https://searchbreast.org.

    The objective of the study was to demonstrate spontaneous contractile activity of the smooth muscle coat of the aorta in human and animal material. Spontaneous contractility of smooth muscle tissue, or tonus, is essential for the proper function of many internal organs as observed in the many types of muscle cells which make up the internal structures. The spontaneous contractile activity of the muscle tissue in blood vessels is particularly marked in resistance vessels, regulating circulation within organs or tissues. It can also be observed in large blood vessels such as arteries and veins. The contractile activity of muscular tissue isolated from arteries is the result of a number of factors, including endogenous paracrine substances, neurotransmitters released at postganglionic endings (mostly within the sympathetic system), cells capable of spontaneously generation of functional potentials (pacemaking cells) and the vascular endothelium. Pacemaking cells present in the aortic wall are an important factor in the development of the spontaneous contractility of the muscular coat of the aorta. They are capable of generating functional potentials, resulting in the constant tonus of the smooth muscular coat (comprising the aortic wall) due to tonic contraction. In vitro studies were carried out on abdominal aortic sections collected from 30 New Zealand rabbits with a body mass of 3-4 kilograms each and also on aneurysmal abdominal aortic sections collected during elective aneurysm repair procedures in humans (10 abdominal aortic sections). The 1.5 cm-long sections were mounted in chambers of an automated water bath. The sections were oriented in a transverse and longitudal fashion in order to compare contractility. The incubation medium consisted of Krebs-Henseleit buffer. Spontaneous contractile activity was observed during the study, characterized by rhythmic contractions of the muscular layer of the aorta. The contractile tension within the sections was 0.15 m

    Events induced by ionizing radiation are exploited in diverse fields of scientific research, and the application of this technology has for many years offered advantages over alternative approaches. Mos biological research institutes are equipped with X-ray or gamma ray irradiations, which are used for a number of research purposes. The risk associated with the use of this equipment is negligible, since radiation sources are effectively shielded and the apparatus is fitted with multiple safety mechanisms. In addition, in type A gamma biological irradiators with a self shielded source, the gamma emitter cannot be accessed by operators, increasing operational safety. this type of gamma irradiator can be used for irradiation of experimental animals and various kinds of tissue sample, and is a standard methodology for biological research in fields such as cardiovascular research and cancer.

    The description and differentiation of the so-called "Cold" and "Hot" natures,the primary "Drug Naure" of Chinese medicine,is the focus of theoretical research.In this study,the divergency between the "Cold" and the "Hot" natures was investigated through examining the temperature tropism of mice affected by Coptis chinensis Franch and its processed materials by using a cold/hot plate differentiating technology.After exposure to C.chinensis Franch,the macroscopic behavioral index of the remaining rate (RR)on a warm pad (40℃)significantly increased (P<0.05),suggesting the enhancement of Hot tropism.The internal indexes of adenosine triphosphatase (ATPase)activity and oxygen consuming volume decreased significantly (P<0.05),suggesting the decapability of energy metabolism.This external behavior of Hot tropism might reflect the internal Cold nature of C.chinensis Franch.However,the processed materials of C.chinensis Franch exhibited a different Cold nature in temperature tropism compared with crude C.chinensis Franch (CC):the Cold nature of bile-processed C.chinensis Franch (BC)enhanced while the ginger-processed C.chinensis Franch (GC)changed inversely.The changing sequence was consistent with the theoretical prognostication.It is indicated that the external Cold & Hot natures of Chinese medicine may possibly reflect in an ethological way for the changes of animal's temperature tropism which might be internally regulated by the body's energy metabolism.

    Full Text Available In this study, the amount of cement used in a concrete mix is minimized to reduce the toxic effects on users by adjusting the concrete mixture contents. The reduction of cement is achieved by using various admixtures (ground granulated blast-furnace slag, flyash, ordinary Portland cement, and activated Hwangtoh powder. To apply the mix to construction, material property tests such as compressive strength, slump, and pH are performed. Preliminary experimental results showed that the Hwangtoh concrete could be used as a healthy construction material. Also, the health issues and effects of Hwangtoh mortar are quantitatively evaluated through an animal clinical test. Mice are placed in Hwangtoh mortar and cement mortar cages to record their activity. For the test, five cages are made with Hwangtoh and ordinary Portland cement mortar floors, using Hwangtoh powder replacement ratios of 20%, 40%, 60%, and 80% of the normal cement mortar mixing ratio, and two cages are made with Hwangtoh mortar living quarters. The activity parameter measurements included weight, food intake, water intake, residential space selection, breeding activity, and aggression. The study results can be used to evaluate the benefits of using Hwangtoh as a cement replacing admixture for lifestyle, health and sustainability.

    Full Text Available Lower limb prosthetic socket shape and volume consistency can be quantified using MRI technology. Additionally, MRI images of the residual limb could be used as an input data for CAD-CAM technology and finite element studies. However, the accuracy of MRI when socket casting materials are used has to be defined. A number of six, 46 mm thick, cross-sections of an animal leg were used. Three specimens were wrapped with Plaster of Paris (POP and the other three with commercially available silicone interface liner. Data was obtained by utilising MRI technology and then the segmented images compared to corresponding calliper measurement, photographic imaging, and water suspension techniques. The MRI measurement results were strongly correlated with actual diameter, surface area, and volume measurements. The results show that the selected scanning parameters and the semiautomatic segmentation method are adequate enough, considering the limit of clinical meaningful shape and volume fluctuation, for residual limb volume and the cross-sectional surface area measurements.

    In 1994 the Israeli parliament (Knesset) amended the Cruelty to Animals Act to regulate the use of experimental animals. Accordingly, animal experiments can only be carried out for the purposes of promoting health and medical science, reducing suffering, advancing scientific research, testing or production of materials and products (excluding cosmetics and cleaning products) and education. Animal experiments are only permitted if alternative methods are not possible. The National Board for Animal Experimentation was established to implement the law. Its members are drawn from government ministries, representatives of doctors, veterinarians, and industry organizations, animal rights groups, and academia. In order to carry out an animal experiment, the institution, researchers involved, and the specific experiment, all require approval by the Board. To date the Board has approved some 35 institutions, about half are public institutions (universities, hospitals and colleges) and the rest industrial firms in biotechnology and pharmaceutics. In 2000, 250,000 animals were used in research, 85% were rodents, 11% fowls, 1,000 other farm animals, 350 dogs and cats, and 39 monkeys. Academic institutions used 74% of the animals and industry the remainder. We also present summarized data on the use of animals in research in other countries.

Practical feasibility of using a vegetable fats complex and Milk Protein-Carbohydrate Concentrate (MPCC «Lactobel-ED» in sausage production has been found. The levels of adding to the formula have been proved. Thermodenaturation of milk and whey proteins during thickening and drying of “Lactobel-ED” increases the availability of peptide chains and ionized amino acid residues. Solubility study showed that the concentrate is highly soluble in aqueous solutions, but this has a high dispersion degree, which increases the overall adsorption surface. Analysis of the results of structural and mechanical changes in the characteristics of minced model systems indicates a decline in YV of prototypes with sunflower oil on average 99.5 Pa.

    Millions of animals are used every year in often times extremely painful and distressing scientific procedures. Legislation of animal experimentation in modern societies is based on the supposition that this is ethically acceptable when certain more or less defined formal (e.g. logistical, technical) demands and ethical principles are met. The main parameters in this context correspond to the "3Rs" concept as defined by Russel and Burch in 1959, i.e. that all efforts to replace, reduce and refine experiments must be undertaken. The licensing of animal experiments normally requires an ethical evaluation process, often times undertaken by ethics committees. The serious problems in putting this idea into practice include inter alia unclear conditions and standards for ethical decisions, insufficient management of experiments undertaken for specific (e.g. regulatory) purposes, and conflicts of interest of ethics committees' members. There is an ongoing societal debate about ethical issues of animal use in science. Existing EU legislation on animal experimentation for cosmetics testing is an example of both the public will for setting clear limits to animal experiments and the need to further critically examine other fields and aspects of animal experimentation.

    NASA Langley Research Center has successfully developed an electron beam freeform fabrication (EBF3) process, a rapid metal deposition process that works efficiently with a variety of weldable alloys. The EBF3 process can be used to build a complex, unitized part in a layer-additive fashion, although the more immediate payoff is for use as a manufacturing process for adding details to components fabricated from simplified castings and forgings or plate products. The EBF3 process produces structural metallic parts with strengths comparable to that of wrought product forms and has been demonstrated on aluminum, titanium, and nickel-based alloys to date. The EBF3 process introduces metal wire feedstock into a molten pool that is created and sustained using a focused electron beam in a vacuum environment. Operation in a vacuum ensures a clean process environment and eliminates the need for a consumable shield gas. Advanced metal manufacturing methods such as EBF3 are being explored for fabrication and repair of aerospace structures, offering potential for improvements in cost, weight, and performance to enhance mission success for aircraft, launch vehicles, and spacecraft. Near-term applications of the EBF3 process are most likely to be implemented for cost reduction and lead time reduction through addition of details onto simplified preforms (casting or forging). This is particularly attractive for components with protruding details that would require a significantly large volume of material to be machined away from an oversized forging, offering significant reductions to the buy-to-fly ratio. Future far-term applications promise improved structural efficiency through reduced weight and improved performance by exploiting the layer-additive nature of the EBF3 process to fabricate tailored unitized structures with functionally graded microstructures and compositions.

    Descriptive geometry is very important and recognized as a basic skill and knowledge for mechanical engineering student. In this study, PC-based electronic teaching/learning materials for descriptive geometry are created using Flash®, which is a typical animation creator. Furthermore, several axonometric representations, created by 3D-CAD, SolidWorks®, for 3D objects are auxiliary materials to promote understanding of descriptive geometry. The axonometric representations in 3D-CAD are also dynamic, in other words, a viewpoint can be moved free. The movement of 3D model in a PC monitor can be recorded using a normal function of SolidWorks and replayed by typical animation software. The developed materials are excellent at accuracy of drawing, repeatability of self-study and visual attraction in comparison to oral presentation using still image and inaccurate drawing on a textbook or blackboard in a classroom. Actually, questionnaire survey results present favorable impressions from student-users, although they point out the further improvement in the replaying speed. The replaying speed can be controlled easily by using a normal function of Flash®. In addition, usual playback software for animation has functions of pause and replay on demand and, thus, it is not contro-versial.

    Full Text Available A biotecnologia animal tem fornecido novas ferramentas para os programas de melhoramento e, dessa forma, contribuído para melhorar a eficiência da produção dos produtos de origem animal. No entanto, os avanços têm sido mais lentos do que antecipados, especialmente em razão da dificuldade na identificação dos genes responsáveis pelas características fenotípicas de interesse zootécnico. Três estratégias principais têm sido utilizadas para identificar esses genes - mapeamento de QTL, genes candidatos e sequenciamento de DNA e mRNA - e cada uma tem suas vantagens e limitações. O mapeamento de QTL permite determinar as regiões genômicas que contêm genes, mas o intervalo de confiança do QTL pode ser grande e conter muitos genes. A estratégia de genes candidatos é limitada por causa do conhecimento ainda restrito das funções de todos os genes. Os sequenciamentos de genomas e de sequências expressas podem auxiliar na identificação da posição de genes e de vias metabólicas associadas à característica de interesse. A integração dessas estratégias por meio do desenvolvimento de programas de bioinformática permitirá a identificação de novos genes de interesse zootécnico. Assim, os programas de melhoramento genético se beneficiarão pela inclusão da informação obtida diretamente do DNA na avaliação do mérito genético dos plantéis disponíveis.Animal biotechnology is providing new tools for animal breeding and genetics and thus contributing to advances in production efficiency and quality of animal products.

    Full Text Available Snakehead fish meat contains active ingredients with anti-aging potential that serves as a precursor of glutathione. The ability of glutathione as an antiaging opportunities in the utilization of fish meat, especially snakehead fish. Snakehead fish meat contains several important amino acids, such as glutamine, cysteine​​, and glycine so the potential to be developed for the production of food that is nutritious and healthy. This study examines the essential amino acid composition of the antioxidant glutathione precursors found in snakehead fish from Rawa Pening Central Java to increase glutathione in the body and brain. The results showed that every 100g of snakehead fish meat from Rawa Pening containing glutamine (32.39%, cysteine ​​(6.61%, and glycine (9.69%. Snakehead fish meat extract given at a dose of 30 ml/kg/day in both types of animal models of aging effect on the increase in the content of glutathione and glutathione precursors, both in blood and hippocampus. Increased glutathione precursor of the most high to low, respectively glutamine, glycine, and cysteine​​. Availability of essential amino acids can support increased glutathione in the brain. This is indicated by an increase in glutathione hippocampus in both animal models, both on chronological aging or aging due to oxidative stress, respectively (0.822 and 0.359 mol/g bb compared to control tissue.

    The influence of the type of material used, knot configuration, and use of an additional throw on the tensile force at failure, the elongation, and the mode of failure of different configurations of linear sutures and knotted suture loops was evaluated in this in-vitro mechanical study. We hypothesized that all types of knots would significantly influence the initial force and elongation of suture materials and would influence the force and elongation at which the knotted loops break, but not their mode of failure. A total of 432 samples of 4 types of size 3-0 suture material (polydioxanone, polyglecaprone 25, polyglactin 910, and nylon), representing 9 configurations, were tested in a tensiometer. The configurations were 1 linear suture without a knot and the following loops: square (SQ) knot; surgeon's (SU) knot; granny (GR) knot; and sliding half-hitch (SHH) knot using either 4 and 5 or 3 and 4 throws, depending on the material. For polydioxanone, SQ and SU knots did not decrease the initial force at failure of the suture. Granny (GR) and SHH knots decreased the tensile force at failure and elongation by premature failure of the loop. For polyglecaprone 25, all knots decreased the initial force at failure of the suture, with SHH being weaker than the other knots. For coated polyglactin 910, all knots decreased the initial force at failure of the suture and slippage increased significantly compared with the other 3 sutures. The use of SQ knots with 3 throws did not result in a safe knot. For nylon, knots did not alter the original mechanics of the suture. In conclusion, all knots and types of suture material do not necessarily have the same effect on the initial tensile force at failure of suture materials.

    The development of a new anticancer drug is a long, complex and multistep process which is supervised by regulatory authorities from the different countries all around the world [1]. Application of a new drug for admission to the market is supported by preclinical and clinical data, both including the determination of pharmacodynamics, toxicity, antitumour activity, therapeutic index, etc. As preclinical studies are associated with high cost, optimization of animal experiments is crucial for the overall development of a new anticancer agent. Moreover, in vivo efficacy studies remain a determinant panel for advancement of agents to human trials and thus, require cautious design and interpretation from experimental and ethical point of views.

    We love movies because we like to jump from our “reality” to live a dream, a parallel universe that inspires us. We long for adventure, excitement and answers to quests… That’s the magic of cinema; it makes you believe what you see and over all, FEEL it. As Antonio Damasio said-“ we´re feeling...... machines that think”-(Damasio, A. Descartes error). Such feelings come from the interpretation of the emotions in our bodies. Emotions are our universal language, the motivation of living, the key to what makes a movie successful and truly an art piece that you will remember because moves you. Animation...

  14. Prevalence of diarrhea-associated virulence genes and genetic diversity in Escherichia coli isolates from fecal material of various animal hosts.

    In order to assess the health risk associated with a given source of fecal contamination using bacterial source tracking (BST), it is important to know the occurrence of potential pathogens as a function of host. Escherichia coli isolates (n=593) from the feces of diverse animals were screened for various virulence genes: stx1 and stx2 (Shiga toxin-producing E. coli [STEC]), eae and EAF (enteropathogenic E. coli [EPEC]), STh, STp, and LT (enterotoxigenic E. coli [ETEC]), and ipaH (enteroinvasive E. coli [EIEC]). Eleven hosts were positive for only the eae (10.11%) gene, representing atypical EPEC, while two hosts were positive for both eae and EAF (1.3%), representing typical EPEC. stx1, stx2, or both stx1 and stx2 were present in 1 (0.1%,) 10 (5.56%), and 2 (1.51%) hosts, respectively, and confirmed as non-O157 by using a E. coli O157 rfb (rfbO157) TaqMan assay. STh and STp were carried by 2 hosts (2.33%) and 1 host (0.33%), respectively, while none of the hosts were positive for LT and ipaH. The repetitive element palindromic PCR (rep-PCR) fingerprint analysis identified 221 unique fingerprints with a Shannon diversity index of 2.67. Multivariate analysis of variance revealed that majority of the isolates clustered according to the year of sampling. The higher prevalence of atypical EPEC and non-O157 STEC observed in different animal hosts indicates that they can be a reservoir of these pathogens with the potential to contaminate surface water and impact human health. Therefore, we suggest that E. coli from these sources must be included while constructing known source fingerprint libraries for tracking purposes. However, the observed genetic diversity and temporal variation need to be considered since these factors can influence the accuracy of BST results.

  15. Using Rose’s metal alloy as a pinhole collimator material in preclinical small-animal imaging: A Monte Carlo evaluation

    Purpose: Pinhole collimation is the most common method of high-resolution preclinical single photon emission computed tomography imaging. The collimators are usually constructed from dense materials with high atomic numbers, such as gold and platinum, which are expensive and not always flexible in the fabrication step. In this work, the authors have investigated the properties of a fusible alloy called Rose’s metal and its potential in pinhole preclinical imaging. When compared to current standard pinhole materials such as gold and platinum, Rose’s metal has a lower density and a relatively low effective atomic number. However, it is inexpensive, has a low melting point, and does not contract when solidifying. Once cast, the piece can be machined with high precision. The aim of this study was to evaluate the imaging properties for Rose’s metal and compare them with those of standard materials. Methods: After validating their Monte Carlo code by comparing its results with published data and the results from analytical calculations, they investigated different pinhole geometries by varying the collimator material, acceptance angle, aperture diameter, and photon incident angle. The penetration-to-scatter and penetration-to-total component ratios, sensitivity, and the spatial resolution were determined for gold, tungsten, and Rose’s metal for two radionuclides, {sup 99}Tc{sup m} and {sup 125}I. Results: The Rose’s metal pinhole-imaging simulations show higher penetration/total and scatter/total ratios. For example, the penetration/total is 50% for gold and 75% for Rose’s metal when simulating {sup 99}Tc{sup m} with a 0.3 mm aperture diameter and a 60° acceptance angle. However, the degradation in spatial resolution remained below 10% relative to the spatial resolution for gold for acceptance angles below 40° and aperture diameters larger than 0.5 mm. Conclusions: Extra penetration and scatter associated with Rose’s metal contribute to degradation in the

    A recent paper famously accused the rising field of social neuroscience of using faulty statistics under the catchy title ‘Voodoo Correlations in Social Neuroscience’. This Special Issue invites us to take this claim as the starting point for a cross-cultural analysis: in which meaningful ways can recent research in the burgeoning field of functional imaging be described as, contrasted with, or simply compared to animistic practices? And what light does such a reading shed on the dynamics and effectiveness of a century of brain research into higher mental functions? Reviewing the heated debate from 2009 around recent trends in neuroimaging as a possible candidate for current instances of ‘soul catching’, the paper will then compare these forms of primarily image-based brain research with older regimes, revolving around the deciphering of the brain’s electrical activity. How has the move from a decoding paradigm to a representational regime affected the conceptualisation of self, psyche, mind and soul (if there still is such an entity)? And in what ways does modern technoscience provide new tools for animating brains? PMID:27292322

    Science.gov (United States)

    Koknaroglu, H; Akunal, T

    2013-12-01

    Increasing world population and demand for animal-derived protein puts pressure on animal production to meet this demand. For this purpose animal breeding efforts were conducted to obtain the maximum yield that the genetic makeup of the animals permits. Under the influence of economics which is the driving force behind animal production, animal farming became more concentrated and controlled which resulted in rearing animals under confinement. Since more attention was given on economics and yield per animal, animal welfare and behavior were neglected. Animal welfare which can be defined as providing environmental conditions in which animals can display all their natural behaviors in nature started gaining importance in recent years. This does not necessarily mean that animals provided with good management practices would have better welfare conditions as some animals may be distressed even though they are in good environmental conditions. Consumers are willing to pay more for welfare-friendly products (e.g.: free range vs caged egg) and this will change the animal production practices in the future. Thus animal scientists will have to adapt themselves for the changing animal welfare rules and regulations that differ for farm animal species and countries. In this review paper, animal welfare is discussed from an animal science standpoint.

    Medicinal animals are important part of Traditional Chinese medicine resources in China. Cytochrome c oxidase subunit I (COI) was selected as the standard DNA barcoding sequence for animal medical materials. In this study, the 51 animal species from 45 animal medical materials in the Chinese Pharmacopoeia were selected and the intra-specific variation and the inter-specific divergence, the barcoding gap, the identification efficiency of their COI sequences were analyzed. The results showed that the inter-specific divergence is higher than intra-specific distance. The barcoding gap existed between inter-specific sequence divergence and intra-specific dis-tance. The identification efficiencies were 100% both at the genus and species level except the Arthropoda. The cluster dendrogram exhibited that different species distinguished from others. Therefore, COI sequence as a bar-code is suitable to identify the species of animal medical materials in Chinese Pharmacopoeia.%  药用动物是我国中药资源的重要组成部分,线粒体 COI基因被公认为动物界中标准的DNA条形码基因,但利用此技术系统研究药用动物或动物药材鉴定的报道不多。本研究选取药典中45个动物药材,涉及基原物种51种,分析样品 COI 序列的种内种间变异情况,barcoding gap,鉴定效率等,考察 COI 序列鉴定动物药材的有效性和准确性。结果表明,种间变异最小值远大于种内变异最大值,barcoding gap 图显示种间变异和种内变异重合较少,鉴定效率较高,除节肢动物门外,在物种水平和属水平上,鉴定效率均为100%,所构建的动物药材及其混伪品的 NJ 树能很好地区分正品来源与其混伪品。因此 COI序列作为 DNA条形码适用于药典中动物药材的鉴定。本研究为COI条形码准确鉴定药典中动物药材提供了分子依据,扩充了 DNA 条形码数据库中药用动物序列,并建立了利用此技术鉴定

    An animal litter composition that includes geopolymerized ash particulates having a network of repeating aluminum-silicon units is described herein. Generally, the animal litter is made from a quantity of a pozzolanic ash mixed with an alkaline activator to initiate a geopolymerization reaction that forms geopolymerized ash. This geopolymerization reaction may occur within a pelletizer. After the geopolymerized ash is formed, it may be dried and sieved to a desired size. These geopolymerized ash particulates may be used to make a non-clumping or clumping animal litter or other absorbing material. Aluminum sulfate, clinoptilolite, silica gel, sodium alginate and mineral oil may be added as additional ingredients.

    An enclosure or burrow restrains an awake animal during an imaging procedure. A tubular body, made from a radiolucent material that does not attenuate x-rays or gamma rays, accepts an awake animal. A proximal end of the body includes an attachment surface that corresponds to an attachment surface of an optically transparent and optically uniform window. An anti-reflective coating may be applied to an inner surface, an outer surface, or both surfaces of the window. Since the window is a separate element of the enclosure and it is not integrally formed as part of the body, it can be made with optically uniform thickness properties for improved motion tracking of markers on the animal with a camera during the imaging procedure. The motion tracking information is then used to compensate for animal movement in the image.

    Hundreds of thousands of laboratory animals are being used every year for scientific experiments held in Israel, mostly mice, rats, rabbits, guinea pigs, and a few sheep, cattle, pigs, cats, dogs, and even a few dozen monkeys. In addition to the animals sacrificed to promote scientific research, millions of animals slain every year for other purposes such as meat and fine leather fashion industries. While opening a front against all is an impossible and perhaps an unjustified task, the state of Israel enacted the Animal Welfare (Animal Experimentation) Law (1994). The law aims to regulate scientific animal experiments and to find the appropriate balance between the need to continue to perform animal experiments for the advancement of research and medicine, and at the same time to avoid unnecessary trials and minimize animal suffering. Among other issues the law deals with the phylogenetic scale according to which experimental animals should be selected, experiments for teaching and practicing, and experiments for the cosmetic industry. This article discusses bioethics considerations in animal experiments as well as the criticism on the scientific validity of such experiments. It further deals with the vitality of animal studies and the moral and legal obligation to prevent suffering from laboratory animals.

    Directory of Open Access Journals (Sweden)

    Vučinić Marijana

    2008-01-01

    Full Text Available The paper deals with animal welfare definitions and animal welfare assessment. Animal welfare is a prolonged mental state, resulting from how the animal experiences its environment over time. There are different methods for animal welfare assessment. The four basic criteria for animal welfare assessment are feeding, housing, health and appropriate behavior. Therefore, criteria used to assess animal welfare are not direct measures of the mental state but only parameters that need to be interpreted in terms of welfare. The immediate housing environment and feeding may influence animal welfare either positively, when most of the important requirements are respected, or negatively, when animals are exposed to various stress factors and unpleasant emotions that contribute to animal disease, injuries or inappropriate behavior. Therefore, animal welfare is a unique link between housing conditions, feeding and watering on one side, and animal health status and behavior on the other side.

    Jaya Sre Varsihini C; Devlina Das; Nilanjana Das

    2014-01-01

    Response surface methodology (RSM) employing 5-level Box-Behnken design was used to optimize the biosorption of ce-rium(III) onto biowaste materials of animal and plant origin viz. prawn carapace (PC) and corn style (CS). Various process parame-ters viz. pH (A:3.0-9.0), biomass dosage (B:0.05-0.35 g/L), initial metal concentration (C:50-350 mg/L), contact time (D:2-6 h) and temperature (E:20-60 °C) were chosen for optimization. A log transformation was suggested by the Box-Cox plot in the present case. A low p-value of<0.0001 validated the significance of the model. Maximum Ce(III) uptake of 218.3 mg/g for PC and 180.2 mg/g for CS was noted under optimum conditions. Among the equilibrium isotherms, Freundlich model was found to be the best fit-ted one suggesting a heterogeneous mode of biosorption on PC whereas Langmuir model showed the best fit suggesting homogene-ous mode of cerium biosorption on CS. This was further confirmed by scanning electron microscopy (SEM). Kinetic studies showed better applicability of pseudo-first order model suggesting physisorption as phenomena underlying the process. Film-diffusion was suggested by the non-linearity of the Boyd plot. Thermodynamic studies showed that the process was endothermic and spontaneous. FTIR analysis confirmed a major involvement of the participation of amide, amines, ketones and primary alcohol groups during Ce(III) biosorption. EDAX analysis confirmed the major participation of carbon group during Ce(III) biosorption. This was the first report on parameter optimization of Ce(III) biosorption onto biowaste materials using 5-level Box-Behnken experimental design which might be helpful for the recovery of Ce(III) from aqueous environment.

    This article discusses the notion that the invisibility of the animalness of the animal constitutes a fundamental obstacle to change within current production systems. It is discussed whether housing animals in environments that resemble natural habitats could lead to a re-animalization...... of the animals, a higher appreciation of their moral significance, and thereby higher standards of animal welfare. The basic claim is that experiencing the animals in their evolutionary and environmental context would make it harder to objectify animals as mere bioreactors and production systems. It is argued...... that the historic objectification of animals within intensive animal production can only be reversed if animals are given the chance to express themselves as they are and not as we see them through the tunnel visions of economy and quantifiable welfare assessment parameters....

  19. Animal rights, animal minds, and human mindreading.

    Science.gov (United States)

    Mameli, M; Bortolotti, L

    2006-02-01

    Do non-human animals have rights? The answer to this question depends on whether animals have morally relevant mental properties. Mindreading is the human activity of ascribing mental states to other organisms. Current knowledge about the evolution and cognitive structure of mindreading indicates that human ascriptions of mental states to non-human animals are very inaccurate. The accuracy of human mindreading can be improved with the help of scientific studies of animal minds. However, the scientific studies do not by themselves solve the problem of how to map psychological similarities (and differences) between humans and animals onto a distinction between morally relevant and morally irrelevant mental properties. The current limitations of human mindreading-whether scientifically aided or not-have practical consequences for the rational justification of claims about which rights (if any) non-human animals should be accorded.

    The use of animals in research will be necessary for scientific advances in the basic and biomedical sciences for the foreseeable future.As we learn more about the ability of animals to experience pain,suffering,and distress,and particularly for mammals,it becomes the responsibility of scientists,institutions,animal caregivers,and veterinarians to seek ways to improve the lives of research animals and refine their care and use.Refinement is one of the three R's emphasized by Russell and Burch,and refers to modification of procedures to minimise the potential for pain,suffering and distress. It may also refer to procedures used to enhance animal comfort. This paper summarizes considerations for refinements in research animal.

    Full Text Available Nowadays, learning a foreign language becomes necessary; the importance of teaching Turkish to the foreigners is getting more and more. Although Turkish is a rooted language, it is quite a new field to teach Turkish as a foreign language. Varies studies have been applied on teaching Turkish as s foreign language and came a long way. However, when it is examined, it can be seen that one of the most common problems of teaching Turkish to the foreigners is the lack of teaching materials. Animation as a material used in teaching Turkish to the foreigners has become remarkable day by day. In foreign language teaching, visuality is an important factor on permanent learning, thus animation plays an important role in teaching foreign languages. In this study aiming at using animation as an alternative to the lack of materials and to provide permanent learning, activities are developed according to the Common European Framework of Reference. Activities are designed by using the animation “Bee Movie” produced in 2007. The activities are prepared to develop main language skills (listening, writing, speaking and reading on A1 level. In each activity, duration, target language skill, educational attainment, materials and application of the activities have been explained. In this study it is expressed that these activities will be a solution for material scarcity by enriching the learning atmosphere, increasing student motivation, providing individual education, providing the improvement of students’ language skills, converting abstract topics into concrete and providing permanent learning.

    2000-08-01

    Students enrolled in the laboratory animal science graduate program at MCP Hahnemann University seek to gain entrance to veterinary school or to manage an animal facility within an academic institution, pharmaceutical or biotechnology company conducting biomedical research. Ongoing interaction between faculty in the radiation oncology, radiation safety, and lab animal science disciplines revealed an acute need for radiation safety education for laboratory animal science students who will likely interact with researchers either designing and writing protocols for animal studies using radiation or radioactive materials, or veterinary staff who will use sources of radiation to diagnose and/or treat possible animal injuries and diseases. A core course in the Radiation Sciences graduate program was modified to address the needs of these students, instructing them in radiation safety, detection and counting instrumentation, and radiation biology. These fundamental areas were integrated to help the students gain a sound, basic knowledge of radiation and radioactive materials used in biomedical research.

  6. Animal husbandry and experimental design.

    Science.gov (United States)

    Nevalainen, Timo

    2014-01-01

    If the scientist needs to contact the animal facility after any study to inquire about husbandry details, this represents a lost opportunity, which can ultimately interfere with the study results and their interpretation. There is a clear tendency for authors to describe methodological procedures down to the smallest detail, but at the same time to provide minimal information on animals and their husbandry. Controlling all major variables as far as possible is the key issue when establishing an experimental design. The other common mechanism affecting study results is a change in the variation. Factors causing bias or variation changes are also detectable within husbandry. Our lives and the lives of animals are governed by cycles: the seasons, the reproductive cycle, the weekend-working days, the cage change/room sanitation cycle, and the diurnal rhythm. Some of these may be attributable to routine husbandry, and the rest are cycles, which may be affected by husbandry procedures. Other issues to be considered are consequences of in-house transport, restrictions caused by caging, randomization of cage location, the physical environment inside the cage, the acoustic environment audible to animals, olfactory environment, materials in the cage, cage complexity, feeding regimens, kinship, and humans. Laboratory animal husbandry issues are an integral but underappreciated part of investigators' experimental design, which if ignored can cause major interference with the results. All researchers should familiarize themselves with the current routine animal care of the facility serving them, including their capabilities for the monitoring of biological and physicochemical environment.

  7. Carotenoids in Marine Animals

    Directory of Open Access Journals (Sweden)

    Takashi Maoka

    2011-02-01

    Full Text Available Marine animals contain various carotenoids that show structural diversity. These marine animals accumulate carotenoids from foods such as algae and other animals and modify them through metabolic reactions. Many of the carotenoids present in marine animals are metabolites of β-carotene, fucoxanthin, peridinin, diatoxanthin, alloxanthin, and astaxanthin, etc. Carotenoids found in these animals provide the food chain as well as metabolic pathways. In the present review, I will describe marine animal carotenoids from natural product chemistry, metabolism, food chain, and chemosystematic viewpoints, and also describe new structural carotenoids isolated from marine animals over the last decade.

  11. Animal Images and Metaphors in Animal Farm

    Directory of Open Access Journals (Sweden)

    Ping Sun

    2015-05-01

    Full Text Available In literary works animal images are frequently used as the “source domain” of a metaphor to disclose the natures of the “target domain”, human beings. This is called “cross-domain mapping” or “conceptual metaphor” in cognitive linguistics, which is based on the similar qualities between animals and human beings. Thus the apparent descriptions of the animals are really the deep revelations of the human beings. Animal Farm is one exemplary product of this special expressing way. Diversified animal images are intelligently used by George Orwell to represent the people, so all the characters are animals in appearance, but humans in nature. Starting from the animal images and then the conceptual metaphors, readers can perceive a fresh understanding of this classical book. In this novel, three conceptual metaphors are identified and the special findings can be illustrated as the following: Firstly, the whole story of the animals represents the history and politics of the Soviet Union. Secondly, the pigs symbolize the authorities of the society. Thirdly, the names of the characters in the novel reveal their identities.

    Gaume, J. G.

    1978-01-01

    An animal exposure test system (AETS) was designed and fabricated for the purpose of collecting physiological and environmental (temperature) data from animal subjects exposed to combustion gases in large scale fire tests. The AETS consisted of an open wire mesh, two-compartment cage, one containing an exercise wheel for small rodents, and the other containing one rat instrumented externally for electrocardiogram (ECG) and respiration. Cage temperature is measured by a thermistor located in the upper portion of the rat compartment. Animal activity is monitored by the ECG and the records indicate an increase in EMG (electromyograph) noise super-imposed by the increased activity of the torso musculature. Examples of the recordings are presented and discussed as to their significance regarding toxicity of fire gases and specific events occurring during the test. The AETS was shown to be a useful tool in screening materials for the relative toxicity of their outgassing products during pyrolysis and combustion.

  16. RETHINKING THE ANIMATE, RE-ANIMATING THOUGHT

    Directory of Open Access Journals (Sweden)

    Tim Ingold

    2013-12-01

    Full Text Available Animism is often described as the imputation of life to inert objects. Such imputation is more typical of people in western societies who dream of finding life on other planets than of indigenous peoples to whom the label of animism has classically been applied. These peoples are united not in their beliefs but in a way of being that is alive and open to a world in continuous birth. In this animic ontology, beings do not propel themselves across a ready-made world but rather issue forth through a world-in-formation, along the lines of their relationships. To its inhabitants this weather-world, embracing both sky and earth, is a source of astonishment but not surprise. Re-animating the ‘western’ tradition of thought means recovering the sense of astonishment banished from offi cial science.

    The current state of epidemiological knowledge about BSE clearly indicates that certain practices in carcass rendering had a significant impact on maintenance and spreading of BSE in the cattle population. This awareness did not come up spontaneously. As a reflection community legislation continuously developed and still does. The decisive move was done in the year 2000 by eliminating ruminant tissues with a high infectious potential with regard to BSE (specified risk material--SRM) from the human and animal feed chains. This step as well as the subsequent feed ban for all farm animals dramatically changed the logistical as well as the economical preconditions of the rendering industry. In fact the basic treatment (pressure cooking) remained almost unchanged. But instead of physically recycling the products they are nowadays predominantly used as an energy source in industry. In case of products that originate from the treatment of SRM burning is mandatory. These changes require a well adapted and intensified official supervision.

  5. Germline modification of domestic animals.

    Tang, L; González, R; Dobrinski, I

    2015-01-01

    Genetically-modified domestic animal models are of increasing significance in biomedical research and agriculture. As authentic ES cells derived from domestic animals are not yet available, the prevailing approaches for engineering genetic modifications in those animals are pronuclear microinjection and somatic cell nuclear transfer (SCNT, also known as cloning). Both pronuclear microinjection and SCNT are inefficient, costly, and time-consuming. In animals produced by pronuclear microinjection, the exogenous transgene is usually inserted randomly into the genome, which results in highly variable expression patterns and levels in different founders. Therefore, significant efforts are required to generate and screen multiple founders to obtain animals with optimal transgene expression. For SCNT, specific genetic modifications (both gain-of-function and loss-of-function) can be engineered and carefully selected in the somatic cell nucleus before nuclear transfer. SCNT has been used to generate a variety of genetically modified animals such as goats, pigs, sheep and cattle; however, animals resulting from SCNT frequently suffer from developmental abnormalities associated with incomplete nuclear reprogramming. Other strategies to generate genetically-modified animals rely on the use of the spermatozoon as a natural vector to introduce genetic material into the female gamete. This sperm mediated DNA transfer (SMGT) combined with intracytoplasmatic sperm injection (ICSI) has relatively high efficiency and allows the insertion of large DNA fragments, which, in turn, enhance proper gene expression. An approach currently being developed to complement SCNT for producing genetically modified animals is germ cell transplantation using genetically modified male germline stem cells (GSCs). This approach relies on the ability of GSCs that are genetically modified in vitro to colonize the recipient testis and produce donor derived sperm upon transplantation. As the genetic change

    Love does not necessarily benefit its object, and cost-free love may damage both object and subject. Our love of animals mobilises several distinct human concerns and should not be considered always as a virtue or always as a benefit to the animals themselves. We need to place this love in its full psychological, cultural, and moral context in order to assess what form it ought to take if animals are to benefit from it.

    2008-01-01

    This animation consists of two close-up images of 'Snow Queen,' taken several days apart, by the Robotic Arm Camera (RAC) aboard NASA's Phoenix Mars Lander. Snow Queen is the informal name for a patch of bright-toned material underneath the lander. Thruster exhaust blew away surface soil covering Snow Queen when Phoenix landed on May 25, 2008, exposing this hard layer comprising several smooth rounded cavities beneath the lander. The RAC images show how Snow Queen visibly changed between June 15, 2008, the 21st Martian day, or sol, of the mission and July 9, 2008, the 44th sol. Cracks as long as 10 centimeters (about four inches) appeared. One such crack is visible at the left third and the upper third of the Sol 44 image. A seven millimeter (one-third inch) pebble or clod appears just above and slightly to the right of the crack in the Sol 44 image. Cracks also appear in the lower part of the left third of the image. Other pieces noticeably shift, and some smooth texture has subtly roughened. The Phoenix team carefully positioned and focused RAC the same way in both images. Each image is about 60 centimeters, or about two feet, wide. The object protruding in from the top on the right half of the images is Phoenix's thermal and electrical conductivity probe. Snow Queen and other ice exposed by Phoenix landing and trenching operations on northern polar Mars is the first time scientists have been able to monitor Martian ice at a place where temperatures are cold enough that the ice doesn't immediately sublimate, or vaporize, away. The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif.

    Directory of Open Access Journals (Sweden)

    K. L. Phaniraja

    Full Text Available With the modernization of agriculture, the use of mechanical power in agriculture has increased but draught animal power (DAP continues to be used on Indian farms due to small holdings and hill agriculture. More than 55% of the total cultivated area is still being managed by using draught animals as against about 20% by tractors. India possessed the finest breeds of draught animals. Bullocks, buffaloes and camels are the major draught animals for field operations. Horses, mules, donkeys, yak and mithun are the pack animals for transport. The quality of work from the draught animals depends upon the power developed by them. The design of traditional implements is based on long experience and these have served the purpose of the farmers. However there is plenty of scope to improve the design based on animal-machine-environment interaction so as to have more output and increased efficiency without jeopardizing animal health.

    2009-01-01

    The understanding about the utilization of experimental animals in scientific research and in teaching is many times a complex issue. Special attention needs to be paid to attain the understanding by the general public of the importance of animal experimentation in experimental research and in undergraduate medical teaching. Experimental teaching and research based on the availability of animals for experimentation is important and necessary for the personal and scientific development of the physician-to-be. The technological arsenal which intends to mimic experimentation animals and thus fully replace their use many times does not prove to be compatible with the reality of the living animal. The purpose of this paper is to discuss aspects concerning this topic, bringing up an issue which is complex and likely to arouse in-depth reflections.

  4. Cupper in animal tissues

    Directory of Open Access Journals (Sweden)

    Maximino Huerta Bravo

    2010-12-01

    Full Text Available Cupper is an essential element for plants, animals and humans. Under certain circumstances, cupper excessive consumption could result in animal and human intoxication. In order to ensure safe and innocuous and safe foods for Mexicans, government create legislation as Norma Oficial Mexicana to establish the maximum levels of residues, particularly cupper in liver, kidney and muscle of human consumption animals. Liver in Mexico ruminant animals regularly contain 60 mg Cu/kg, which is the legal limit for this metal. This demands a review of the actual legislation. The strict application of this Norma will limit the commercialization of these viscera, since approximately 50% will exceed the legal limit for cupper. A potential hazard for human health, especially young people, is found in the constant ovine liver consumption feed with animal excretes with higher amount of supplementary cupper.

    2016-09-01

    Recently, short animated image sequences have become very popular in social networks. Most animated images are represented in GIF format. In this paper we propose an animated JPEG format, called aJPEG, which allows the standard JPEG format to be extended in a backward compatible way in order to cope with animated images. After presenting the proposed format, we illustrate it using two prototype applications: the first in form of a GIF-to-aJPEG converter on a personal computer and the second in form of an aJPEG viewer on a smart phone. The paper also reports the performance evaluation of aJPEG when compared to GIF. Experimental results show that aJPEG outperforms animated GIF in both file size overhead and image quality.

    Full Text Available The world of Dermatology is flooded with inflexions among clinical conditions and signs and syndromes; making it interesting, but a tougher subject to remember. Signs and syndromes have always fascinated residents, but simultaneously burdened their minds, as these attractive names are difficult to remember. This work was undertaken to review dermatological conditions and signs based on commonly encountered daily words and objects like animals, etc. Fifty dermatological conditions were found to be based on animal eponyms. For example, the usage of animal terminology in dermatology like leonine facies is present in leprosy, sarcoidosis, mycosis fungoides (MF, and airborne contact dermatitis (ABCD.

    2013-08-20

    A method of making an animal litter that includes geopolymerized ash, wherein, the animal litter is made from a quantity of a pozzolanic ash mixed with a sufficient quantity of water and an alkaline activator to initiate a geopolymerization reaction that forms geopolymerized ash. After the geopolymerized ash is formed, it is dried, broken into particulates, and sieved to a desired size. These geopolymerized ash particulates are used to make a non-clumping or clumping animal litter. Odor control may be accomplished with the addition of a urease inhibitor, pH buffer, an odor eliminating agent, and/or fragrance.

    2017-01-01

    While significant medical breakthroughs have been achieved through using animal models, our experience shows that often there is surplus material remaining that is frequently never revisited but could be put to good use by other scientists. Recognising that most scientists are willing to share this material on a collaborative basis, it makes economic, ethical, and academic sense to explore the option to utilise this precious resource before generating new/additional animal models and associated samples. To bring together those requiring animal tissue and those holding this type of archival material, we have devised a framework called Sharing Experimental Animal Resources, Coordinating Holdings (SEARCH) with the aim of making remaining material derived from animal studies in biomedical research more visible and accessible to the scientific community. We encourage journals, funding bodies, and scientists to unite in promoting a new way of approaching animal research by adopting the SEARCH framework. PMID:28081116

    Degradation of plant material by animals is an important transformation pathway in the nitrogen (N) cycle. During the involved processes, volatile reduced alkaline nitrogen compounds, mainly ammonia (NH3) and aliphatic amines such as trimethylamine (TMA), are formed. Today, animal husbandry is estimated to constitute a main source of aliphatic amines in the atmosphere with TMA being the main emitted compound. Here, we show how the interaction between faeces and urine in animal production systems provides the primary source for agricultural TMA emissions. Excreted urine contains large quantities of urea and TMA-N-oxide, which are transformed into NH3 and TMA, respectively, via enzymatic processes provided by microbes present in faeces. TMA emissions from areas polluted with urine-faeces mixtures are on average of the order of 10 to 50 nmol m-2s-1. Released amines promote secondary aerosol particle formation in the agricultural emission plume. The atmospheric lifetime of TMA, which was estimated to be of the order of 30 to 1000 s, is determined by the condensation onto aerosol particles.

  16. Animal transportation networks.

    Perna, Andrea; Latty, Tanya

    2014-11-01

    Many group-living animals construct transportation networks of trails, galleries and burrows by modifying the environment to facilitate faster, safer or more efficient movement. Animal transportation networks can have direct influences on the fitness of individuals, whereas the shape and structure of transportation networks can influence community dynamics by facilitating contacts between different individuals and species. In this review, we discuss three key areas in the study of animal transportation networks: the topological properties of networks, network morphogenesis and growth, and the behaviour of network users. We present a brief primer on elements of network theory, and then discuss the different ways in which animal groups deal with the fundamental trade-off between the competing network properties of travel efficiency, robustness and infrastructure cost. We consider how the behaviour of network users can impact network efficiency, and call for studies that integrate both network topology and user behaviour. We finish with a prospectus for future research.

    2009-11-01

    The use of alternative methods to animal testing are an integral part of the 3Rs concept (refine, reduce, replace) defined by Russel & Burch in 1959. These approaches include in silico methods (databases and computer models), in vitro physicochemical analysis, biological methods using bacteria or isolated cells, reconstructed enzyme systems, and reconstructed tissues. Emerging "omic" methods used in integrated approaches further help to reduce animal use, while stem cells offer promising approaches to toxicologic and pathophysiologic studies, along with organotypic cultures and bio-artificial organs. Only a few alternative methods can so far be used in stand-alone tests as substitutes for animal testing. The best way to use these methods is to integrate them in tiered testing strategies (ITS), in which animals are only used as a last resort.

    Bobyn, Justin D; Little, David G; Gray, Randolph; Schindeler, Aaron

    2015-04-01

    Multiple techniques designed to induce scoliotic deformity have been applied across many animal species. We have undertaken a review of the literature regarding experimental models of scoliosis in animals to discuss their utility in comprehending disease aetiology and treatment. Models of scoliosis in animals can be broadly divided into quadrupedal and bipedal experiments. Quadrupedal models, in the absence of axial gravitation force, depend upon development of a mechanical asymmetry along the spine to initiate a scoliotic deformity. Bipedal models more accurately mimic human posture and consequently are subject to similar forces due to gravity, which have been long appreciated to be a contributing factor to the development of scoliosis. Many effective models of scoliosis in smaller animals have not been successfully translated to primates and humans. Though these models may not clarify the aetiology of human scoliosis, by providing a reliable and reproducible deformity in the spine they are a useful means with which to test interventions designed to correct and prevent deformity.

    2011-11-01

    Animal fats are generally considered as a source of saturated fatty acids and cholesterol, identified with arteriosclerosis and its clinical complications (cardiovascular diseases with heart attack, stroke, cerebral claudication). The real reason of arteriosclerosis are inflammation states of blood vessel endothelium caused by oxidative stress, hiperhomocysteinemia, hipertrigliceridemia, presence of artificial trans isomers and excess of eicosanoids originated from poliunsaturated fatty acids n-6. Present status of science proves that both saturated fatty acids and cholesterol present in animal food can not cause inflammation state. Moreover, animal fats are source of antioxidants active both in food and in human organism. Due to high oxidative stability animal fats do not make threat to human health. Milk fat, though high content of saturated fatty acids and cholesterol, possesses comprehensive pro-health activity--against arteriosclerosis and cancerogenesis.

    Animal models will continue to be important tools in the quest to understand the contribution of specific genes to establishment of peak bone mass and optimal bone architecture, as well as the genetic basis for a predisposition toward accelerated bone loss in the presence of co-morbidity factors such as estrogen deficiency. Existing animal models will continue to be useful for modeling changes in bone metabolism and architecture induced by well-defined local and systemic factors. However, there is a critical unfulfilled need to develop and validate better animal models to allow fruitful investigation of the interaction of the multitude of factors which precipitate senile osteoporosis. Well characterized and validated animal models that can be recommended for investigation of the etiology, prevention and treatment of several forms of osteoporosis have been listed in Table 1. Also listed are models which are provisionally recommended. These latter models have potential but are inadequately characterized, deviate significantly from the human response, require careful choice of strain or age, or are not practical for most investigators to adopt. It cannot be stressed strongly enough that the enormous potential of laboratory animals as models for osteoporosis can only be realized if great care is taken in the choice of an appropriate species, age, experimental design, and measurements. Poor choices will results in misinterpretation of results which ultimately can bring harm to patients who suffer from osteoporosis by delaying advancement of knowledge.

  11. Theriocide: Naming Animal Killing

    Directory of Open Access Journals (Sweden)

    Piers Beirne

    2014-08-01

    Full Text Available In this essay I recommend ‘theriocide’ as the name for those diverse human actions that cause the deaths of animals. Like the killing of one human by another, theriocide may be socially acceptable or unacceptable, legal or illegal. It may be intentional or unintentional and may involve active maltreatment or passive neglect. Theriocide may occur one-on-one, in small groups or in large-scale social institutions. The numerous and sometimes intersecting sites of theriocide include intensive rearing regimes; hunting and fishing; trafficking; vivisection; militarism; pollution; and human-induced climate change. If the killing of animals by humans is as harmful to them as homicide is to humans, then the proper naming of such deaths offers a remedy, however small, to the extensive privileging of human lives over those of other animals. Inevitably, the essay leads to a shocking question: Is theriocide murder?

  12. Animal Poetry and Empathy

    Directory of Open Access Journals (Sweden)

    Tirza Brüggemann

    2017-04-01

    Full Text Available This article discusses how our ideas of empathy are influenced by the dichotomy of mind versus body, also known as Cartesian dualism. Within the aesthetic field, this dichotomy is seen when researchers define narrative empathy as imaginatively reconstructing the fictional character’s thoughts and feelings. Conversely, the empathy aroused by a non-narrative work of art is seen as an unconscious bodily mirroring of movements, postures or moods. Thinking dualistically does not only have consequences for what we consider human nature; it also affects our view on animals. To show the untenability of dualistic thinking, this article focuses on the animal poetry genre. Using the ideas of the French phenomenologist Maurice Merleau-Ponty, I analyze two animal poems: “Inventing a Horse” by Meghan O’Rourke and “Spermaceti” by Les Murray. The analysis of these two poems suggests that the presiding ideas about aesthetic empathy and empathy in general need re-evaluation.

  13. Animal violence demystified

    Directory of Open Access Journals (Sweden)

    Deepa Natarajan

    2010-04-01

    Full Text Available Violence has been observed in humans and animals alike, indicating its evolutionary/ biological significance. However, violence in animals has often been confounded with functional forms of aggressive behavior. Currently, violence in animals is identified primarily as either a quantitative behavior (an escalated, pathological and abnormal form of aggression characterized primarily by short attack latencies, and prolonged and frequent harm-oriented conflict behaviors or a qualitative one (characterized by attack bites aimed at vulnerable parts of the opponent’s body and context independent attacks regardless of the environment or the sex and type of the opponent. Identification of an operational definition for violence thus not only helps in understanding its potential differences from adaptive forms of aggression but also in the selection of appropriate animal models for both. To begin with, we address this issue theoretically by drawing parallels from research on aggression and appeasement in humans and other animals. We also provide empirical evidences for violence in mice selected for high aggression by comparing our findings with other currently available potentially violent rodent models. The following violence-specific features namely 1. Display of low levels of pre-escalatory/ritualistic behaviors. 2. Immediate and escalated offense durations with low withdrawal rates despite the opponent’s submissive supine and crouching/defeat postures. 3. Context independent indiscriminate attacks aimed at familiar/unfamiliar females, anaesthetized males and opponents and in neutral environments. 4. Orientation of attack-bites toward vulnerable body parts of the opponent resulting in severe wounding 5. Low pre-frontal serotonin (5-HT levels upon repeated aggression. 6. Low basal heart rates and hyporesponsive hypothalamus-pituitary-adrenocortical (HPA axis were identified uniquely in the short attack latency (SAL mice suggesting a qualitative

    First results of this feasibility study showed that evaluation of the stored material of the chronically irradiated dogs with modern molecular biological techniques proved to be successful and extremely promising. Therefore an in deep analysis of at least part of the huge amount of remaining material is of outmost interest. The methods applied in this feasibility study were pathological evaluation with different staining methods, protein analysis by means of immunohistochemistry, strand break analysis with the TdT-assay, DNA- and RNA-analysis as well as genomic examination by gene array. Overall more than 50% of the investigated material could be used. In particular the results of an increased stimulation of the immune system within the dogs of the 3mSv group as both compared to the control and higher dose groups gives implications for the in depth study of the cellular events occurring in context with low dose radiation. Based on the findings of this study a further evaluation and statistically analysis of more material can help to identify promising biomarkers for low dose radiation. A systematic evaluation of a correlation of dose rates and strand breaks within the dog tissue might moreover help to explain mechanisms of tolerance to IR. One central problem is that most sequences for dog specific primers are not known yet. The discovery of the dog genome is still under progress. In this study the isolation of RNA within the dog tissue was successful. But up to now there are no gene arrays or gene chips commercially available, tested and adapted for canine tissue. The uncritical use of untested genomic test systems for canine tissue seems to be ineffective at the moment, time consuming and ineffective. Next steps in the investigation of genomic changes after IR within the stored dog tissue should be limited to quantitative RT-PCR of tested primer sequences for the dog. A collaboration with institutions working in the field of the discovery of the dog genome could

    Full Text Available The paper deals with environmental enrichment for domestic animals at farms, animals in zoos, experimental animals and pet animals. Also, the paper defines and describes different strategies of environmental enrichment. Environmental enrichment is a simple and effective mean of prevention of boredom, behavioral disorders as well as an effective mean of improving animal welfare in farm, zoo, companion and experimental animals. Different items and materials may be used for environmental enrichment. They need to be evaluated for use by taking into account the following: the species of an animal, its needs, habits and capabilities, the type of an enrichment device, the device's ability to stimulate the animal's interest and the safety of the device. Enrichment programmes should always include two forms of enrichment: behavioral enrichment and environmental enrichment. Enrichment comes in many forms such as structural or physical enrichment, sensory enrichment (auditory and olfactory stimulation, dietary enrichment, manipulatable enrichment and social enrichment.

    The use of models in the life sciences has greatly expanded in scope and advanced in technique in recent decades. However, the range, type and complexity of models used in farm animal welfare is comparatively poor, despite the great scope for use of modeling in this field of research. In this paper, we review the different modeling approaches used in farm animal welfare science to date, discussing the types of questions they have been used to answer, the merits and problems associated with the method, and possible future applications of each technique. We find that the most frequently published types of model used in farm animal welfare are conceptual and assessment models; two types of model that are frequently (though not exclusively) based on expert opinion. Simulation, optimization, scenario, and systems modeling approaches are rarer in animal welfare, despite being commonly used in other related fields. Finally, common issues such as a lack of quantitative data to parameterize models, and model selection and validation are discussed throughout the review, with possible solutions and alternative approaches suggested.

    Brucellosis is a highly contagious zoonosis that affects the public health and economic performance of endemic as well as non-endemic countries. In developing nations, brucellosis is often a very common but neglected disease. The purpose of this review is to provide insight about brucellosis in animal populations in Egypt and help to understand the situation from 1986 to 2013. A total of 67 national and international scientific publications on serological investigations, isolation, and biotyping studies from 1986 to 2013 were reviewed to verify the current status of brucellosis in animal populations in Egypt. Serological investigations within the national surveillance program give indirect proof for the presence of brucellosis in cattle, buffaloes, sheep, goats, and camels in Egypt. Serologic testing for brucellosis is a well-established procedure in Egypt, but most of the corresponding studies do not follow the scientific standards. B. melitensis biovar (bv) 3, B. abortus bv 1, and B. suis bv 1 have been isolated from farm animals and Nile catfish. Brucellosis is prevalent nationwide in many farm animal species. There is an obvious discrepancy between official seroprevalence data and data from scientific publications. The need for a nationwide survey to genotype circulating Brucellae is obvious. The epidemiologic situation of brucellosis in Egypt is unresolved and needs clarification.

  8. Cytogenetics in animal production

    Full Text Available Cytogenetics applied to domestic animals is a useful biotechnology to be applied in the genetic improvement of livestock. Indeed, it can be used to select reproducers free chromosome abnormalities which are responsible for abnormal body conformation (aneuploidy, lower fertility (balanced chromosome abnormalities or sterility (sex chromosome abnormalities. Cytogenetics may also be applied to assess environmental pollution by studying animals living in hazardous areas and using them as biological indicators (sentinels. Chromosomes also represent optimal biological structures to study the evolution among related (bovids and unrelated (bovidshumans species, especially using comparative FISH-mapping which is one of the most powerful tools to establish the correct order of loci along chromosomes. These comparisons allow us to transfer useful information from richer genomes (human to those of domestic animals. Moreover, the use of specific molecular markers and the FISH-technique on both mitotic and extended (fiber-FISH chromosomes, has heralded a new era of cytogenetics, allowing swift extension of genetic physical maps, better anchoring of both linkage and RH-maps to specific chromosome regions, and use in a variety of applications (clinical cases, embryo and sperm analyses, evolution. In this study a brief review of these fields of the animal cytogenetics is presented.

    2012-08-01

    Sacrificing model animals is required for developing effective drugs before being used in human beings. In Japan today, at least 4,210,000 mice and other mammals are sacrificed to a total of 6,140,000 per year for the purpose of medical studies. All the animals treated in Japan, including test animals, are managed under control of "Act on Welfare and Management of Animals". Under the principle of this Act, no person shall kill, injure, or inflict cruelty on animals without due cause. "Animal" addressed in the Act can be defined as a "vertebrate animal". If we can make use of invertebrate animals in testing instead of vertebrate ones, that would be a remarkable solution for the issue of animal welfare. Furthermore, there are numerous advantages of using invertebrate animal models: less space and small equipment are enough for taking care of a large number of animals and thus are cost-effective, they can be easily handled, and many biological processes and genes are conserved between mammals and invertebrates. Today, many invertebrates have been used as animal models, but silkworms have many beneficial traits compared to mammals as well as other insects. In a Genome Pharmaceutical Institute's study, we were able to achieve a lot making use of silkworms as model animals. We would like to suggest that pharmaceutical companies and institutes consider the use of the silkworm as a model animal which is efficacious both for financial value by cost cutting and ethical aspects in animals' welfare.

  20. Animal Gaits and Symmetry

    Science.gov (United States)

    Golubitsky, Martin

    2012-04-01

    Many gaits of four-legged animals are described by symmetry. For example, when a horse paces it moves both left legs in unison and then both right legs and so on. The motion is described by two symmetries: Interchange front and back legs, and swap left and right legs with a half-period phase shift. Biologists postulate the existence of a central pattern generator (CPG) in the neuronal system that sends periodic signals to the legs. CPGs can be thought of as electrical circuits that produce periodic signals and can be modeled by systems with symmetry. In this lecture we discuss animal gaits; use gait symmetries to construct a simplest CPG architecture that naturally produces quadrupedal gait rhythms; and make several testable predictions about gaits.

    2015-01-01

    This paper presents a spectral approach to compress dynamic animation consisting of a sequence of homeomor-phic manifold meshes. Our new approach directly compresses the field of deformation gradient defined on the surface mesh, by decomposing it into rigid-body motion (rotation) and non-rigid-body deformation (stretching) through polar decompo-sition. It is known that the rotation group has the algebraic topology of 3D ring, which is different from other operations like stretching. Thus we compress these two groups separately, by using Manifold Harmonics Transform to drop out their high-frequency details. Our experimental result shows that the proposed method achieves a good balance between the reconstruction quality and the compression ratio. We compare our results quantitatively with other existing approaches on animation compression, using standard measurement criteria.

    2016-11-30

    This editorial endorses a diverse approach to the study of animal cognition and emphasizes the theoretical and applied gains that can be made by embracing this approach. This diversity emerges from cross-talk among scientists trained in a variety of backgrounds and theoretical approaches, who study a variety of topics with a range of species. By shifting from an anthropocentric focus on humans and our closest living relatives, and the historic reliance on the lab rat or pigeon, modern students of animal cognition have uncovered many fascinating facets of cognition in species ranging from insects to carnivores. Diversity in both topic and species of study will allow researchers to better understand the complex evolutionary forces giving rise to widely shared and unique cognitive processes. Furthermore, this increased understanding will translate into more effective strategies for managing wild and captive populations of nonhuman species.

    In the past few years, new technologies have arisen that enable higher efficiency of gene editing. With the increase ease of using gene editing technologies, it is important to consider the best method for transferring new genetic material to livestock animals. Microinjection is a technique that has proven to be effective in mice but is less efficient in large livestock animals. Over the years, a variety of methods have been used for cloning as well as gene transfer including; nuclear transfer, sperm mediated gene transfer (SMGT), and liposome-mediated DNA transfer. This review looks at the different success rate of these methods and how they have evolved to become more efficient. As well as gene editing technologies, including Zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and the most recent clustered regulatory interspaced short palindromic repeats (CRISPRs). Through the advancements in gene-editing technologies, generating transgenic animals is now more accessible and affordable. The goals of producing transgenic animals are to 1) increase our understanding of biology and biomedical science; 2) increase our ability to produce more efficient animals; and 3) produce disease resistant animals. ZFNs, TALENs, and CRISPRs combined with gene transfer methods increase the possibility of achieving these goals.

  7. Pain in aquatic animals.

    Science.gov (United States)

    Sneddon, Lynne U

    2015-04-01

    Recent developments in the study of pain in animals have demonstrated the potential for pain perception in a variety of wholly aquatic species such as molluscs, crustaceans and fish. This allows us to gain insight into how the ecological pressures and differential life history of living in a watery medium can yield novel data that inform the comparative physiology and evolution of pain. Nociception is the simple detection of potentially painful stimuli usually accompanied by a reflex withdrawal response, and nociceptors have been found in aquatic invertebrates such as the sea slug Aplysia. It would seem adaptive to have a warning system that allows animals to avoid life-threatening injury, yet debate does still continue over the capacity for non-mammalian species to experience the discomfort or suffering that is a key component of pain rather than a nociceptive reflex. Contemporary studies over the last 10 years have demonstrated that bony fish possess nociceptors that are similar to those in mammals; that they demonstrate pain-related changes in physiology and behaviour that are reduced by painkillers; that they exhibit higher brain activity when painfully stimulated; and that pain is more important than showing fear or anti-predator behaviour in bony fish. The neurophysiological basis of nociception or pain in fish is demonstrably similar to that in mammals. Pain perception in invertebrates is more controversial as they lack the vertebrate brain, yet recent research evidence confirms that there are behavioural changes in response to potentially painful events. This review will assess the field of pain perception in aquatic species, focusing on fish and selected invertebrate groups to interpret how research findings can inform our understanding of the physiology and evolution of pain. Further, if we accept these animals may be capable of experiencing the negative experience of pain, then the wider implications of human use of these animals should be considered.

    Narcolepsy is a debilitating sleep disorder with excessive daytime sleepiness and cataplexy as its two major symptoms. Although this disease was first described about one century ago, an animal model was not available until the 1970s.

    The anesthesia has been improved all over the years. However, it can have impact on health, in both patients and animals anesthetized, as well as professionals exposed to inhaled anesthetics. There is continuing effort to understand the possible effects of anesthetics at molecular levels. Knowing the effects of anesthetic agents on genetic material could be a valuable basic support to better understand the possible mechanisms of these agents. Thus, the purpose of this review is to provide an overview on the genotoxic potential, evaluated in animal models, of many anesthetics that have already been used and those currently used in anesthesia.

    Popper, Arthur N.; Dooling, Robert J.

    2002-11-01

    The earliest studies on animal bioacoustics dealt largely with descriptions of sounds. Only later did they address issues of detection, discrimination, and categorization of complex communication sounds. This literature grew substantially over the last century. Using the Journal of the Acoustical Society of America as an example, the number of papers that fall broadly within the realm of animal sound production, communication, and hearing rose from two in the partial first decade of the journal in the 1930's, to 20 in the 1970's, to 92 in the first 2 years of this millennium. During this time there has been a great increase in the diversity of species studied, the sophistication of the methods used, and the complexity of the questions addressed. As an example, the first papers in JASA focused on a guinea pig and a bird. In contrast, since the year 2000 studies are often highly comparative and include fish, birds, dolphins, dogs, ants, crickets, and snapping shrimp. This paper on the history of animal bioacoustics will consider trends in work over the decades and discuss the formative work of a number of investigators who have spurred the field by making critical theoretical and experimental observations.

  15. ADVANCES IN ANIMAL WELFARE FOR FREE-LIVING ANIMALS.

    Science.gov (United States)

    2016-04-01

    Over several decades, animal welfare has grown into its own free-standing field of scientific study, from its early beginnings in laboratory animal research to eventually include exhibited animals and farm animals. While it has always been present to some degree, consideration of animal welfare for free-ranging animals has lagged behind, developing as a field of study in the last 20 yr or so. Part of that increase was that animal welfare legislation was finally applied to studies being done on free-ranging animals. But it is the appreciation by the biologists and veterinarians working on wild animals, in which the quality of their results is largely controlled by the quality of the animals they use in their studies, which has resulted in increased attention to the well-being or welfare of the animals that they use. Other important influences driving the recognition of wildlife welfare have been changes in the public's expectations of how wild animals are dealt with, a shift in focus of wildlife professionals from managing animals that can be hunted or angled to include nongame species, the decrease in participation in hunting and fishing by members of the public, and the entry of large numbers of women into fish and wildlife agencies and departments and into veterinary medicine. Technical improvements have allowed the safe capture and handling of large or dangerous animals as immobilization drugs and equipment have been developed. The increasing use of sedating drugs allows for handling of animals with reduced stress and other impacts. A number of topics, such as toe-clipping, branding, defining which taxa can or cannot feel pain, catch-and-release fishing, and more, remain controversial within wildlife science. How we treat the wild animals that we deal with defines who we are as wildlife professionals, and animal welfare concerns and techniques for free-ranging animals will continue to develop and evolve.

  4. 动物产品中猪源性和牛源性成分双重荧光PCR检测方法的建立%Identification of Swine-derived and Bovine-derived Materials in Animal Products by Multiplex Fluorescent PCR Assay

    Institute of Scientific and Technical Information of China (English)

    2012-01-01

    [Objective ] To develop a multiplex fluorescent PCR assay method to detect swine-derived and bovine-derived materials in animal products. [ Method ] Two pairs of specific primers and two fluorescent-labled probes were designed and synthesized according to mitochondrial DNA gene sequences. The multiplex fluorescent PCR reaction system was established through the optimized screening of reaction system and reaction conditions, and swine-derived and bovine-derived materials in animal products were detected in the same fluorescent PCR reaction system. Finally, the sensitivity and specificity of the assay were evaluated. [ Result ] The method successfully detected swine-derived and bovine-derived materials from 16 animals.

    Laboratory animals and animal experiments are foundations and important support conditions for life sciences, especially for medical research. The animal experiments have drawn extensive attention from the society because of the ethical issue. This paper takes Wenzhou Medical University as an example to give a brief introduction to the ethical review about laboratory animals in the university so as to further draw attention and concerns from the public about the ethical issue of laboratory animals. We successively introduce its scientific projects, nurturing environment and ethical review of laboratory animals.

    Dermatophytes from animal dermatophytoses were investigated, especially for their teleomorphs and molecular characteristics. Microsporum canis, M. equinum, M. gypseum, M. nanum, Trichophyton equinum, T. mentagrophytes complex, T. rubrum and T. verrucosum were isolated as the etiological agents of animal ringworm in Japan. They were morphologically and biochemically identified and their perfect states were examined. The teleomorph of M. canis was first obtained and reported as Nanizzia otae in 1975. The isolates of M. canis of which the teleomorph was confirmed were all "-" excepted two Japanese isolates. Mating experiments indicated that the isolates of M. gypseum were "+" or "-" of A. gypseum and A. incurvatum, respectively. Most of the isolates of T. mentagrophytes complex of which a perfect state was detected were A. vanbreuseghemii. One isolate from a monkey was A. simii and one from a rabbit was A. benhamiae. However, the teleomorph remained unknown in many isolates. Molecular characteristics in random amplification of polymorphic DNA and Southern hybridization analyses were found to be effective to differentiate the species of Microsporum. Nucleotide sequences of chitin synthase 1 (CHS1) gene of dermatophytes were also analyzed for their phylogenetic relatedness. The phylogenetic analysis revealed four clusters: the first cluster consisted of A. benhamiae, A. simii, A. vanbreuseghemii, T. mentagrophytes var. interdigitale, T. rubrum and T. violaceum; the second of A. fulvum, A. gypseum and A. incurvatum; the third of A. grubyi and A. otae; and the fourth of Epidermaphyton floccosum, providing useful information for the classification and understanding of their evolution.

    Full Text Available The field of mitochondrial DNA (mtDNA replication has been experiencing incredible progress in recent years, and yet little is certain about the mechanism(s used by animal cells to replicate this plasmid-like genome. The long-standing strand-displacement model of mammalian mtDNA replication (for which single-stranded DNA intermediates are a hallmark has been intensively challenged by a new set of data, which suggests that replication proceeds via coupled leading-and lagging-strand synthesis (resembling bacterial genome replication and/or via long stretches of RNA intermediates laid on the mtDNA lagging-strand (the so called RITOLS. The set of proteins required for mtDNA replication is small and includes the catalytic and accessory subunits of DNA polymerase y, the mtDNA helicase Twinkle, the mitochondrial single-stranded DNA-binding protein, and the mitochondrial RNA polymerase (which most likely functions as the mtDNA primase. Mutations in the genes coding for the first three proteins are associated with human diseases and premature aging, justifying the research interest in the genetic, biochemical and structural properties of the mtDNA replication machinery. Here we summarize these properties and discuss the current models of mtDNA replication in animal cells.

    Naturally occurring radioactive materials are present everywhere, e.g., in soil, air, housing materials, food, etc. Therefore, human beings and animals receive internal exposure from radioactive elements inside their bodies through breathing and alimentation. Gamma radiation has enough energy to remove an electron from the atom and compromise the rearrangement of electrons in the search for a more stable configuration which can disturb molecule chemical bonding. Food ingestion is one of the most common forms of radioisotopes absorption. The goal of this work is the measurement of natural gamma radiation rates from natural radioisotopes present in animal food. To determine the concentration of natural radionuclides present in animal food gamma-ray spectrometry was applied. We have prepared animal food samples for poultry, fish, dogs, cats and cattle. The two highest total ingestion effective doses observed refers to a sample of mineral salt cattle, 95.3(15) μSv/year, rabbit chow, with a value of 48(5) μSv/year, and cattle mineral salt, with a value of 69(7) μSv/year, while the annual total dose value from terrestrial intake radionuclide is of the order of 290 μSv/year.

  11. Biomarkers of teratogenesis: suggestions from animal studies.

    2012-09-01

    Biomarkers of effect are measurable biochemical, physiological or other alterations within an organism that can be recognized as causing an established or potential impairment of embryo-fetal development. They may be identified studying the mechanisms of action of teratogens. Hyperacetylation of histones, oxidative stress, cholesterol and retinoic acid unbalance are some of the identified mechanisms of action of some known teratogens. Nevertheless, their use is not currently applicable in human pregnancy because of the difficulty of the choice of biological material, the time when the material must be obtained, and the invasivity of methods. Furthermore, before using them in human pregnancy studies, biomarkers should be validated in experimental animals and in epidemiologic studies. On the contrary, some biomarkers could be useful in the screening of developmental toxicity of chemicals and drugs, comparing molecules of the same chemical class or with the similar pharmacologic activity, and using adequate in vitro tests, in order to reduce the use of experimental animals.

Few objects convey wealth and power like a private airplane, but one day you won't have to be rich or famous to fly one. NASA is working with industry and other government agencies to develop the technology and vision for business and personal travel of the future. It's a future in which travelers fly to their destinations in small, safe, affordable and easy-to-use jets out of 'smart airports.' Future small aircraft may cost about as much as a luxury automobile. They will use 25% less fuel than today's airplanes with fuel efficiencies rivaling automobiles, but at four times highway speeds. The goal is to put 'wings on America' and enable doorstep-to-destination travel at four times the speed of highways, making it possible to go where you want, when you want - faster than ever.

  1. Animal models of narcolepsy.

    Science.gov (United States)

    Chen, Lichao; Brown, Ritchie E; McKenna, James T; McCarley, Robert W

    2009-08-01

    Narcolepsy is a debilitating sleep disorder with excessive daytime sleepiness and cataplexy as its two major symptoms. Although this disease was first described about one century ago, an animal model was not available until the 1970s. With the establishment of the Stanford canine narcolepsy colony, researchers were able to conduct multiple neurochemical studies to explore the pathophysiology of this disease. It was concluded that there was an imbalance between monoaminergic and cholinergic systems in canine narcolepsy. In 1999, two independent studies revealed that orexin neurotransmission deficiency was pivotal to the development of narcolepsy with cataplexy. This scientific leap fueled the generation of several genetically engineered mouse and rat models of narcolepsy. To facilitate further research, it is imperative that researchers reach a consensus concerning the evaluation of narcoleptic behavioral and EEG phenomenology in these models.

  2. Current status of animal welfare and animal rights in China.

    Lu, Jiaqi; Bayne, Kathryn; Wang, Jianfei

    2013-11-01

    In the past few years, new social passions have sparked on the Chinese mainland. At the centre of these burgeoning passions is a focus on animal welfare, animal treatment, and even animal rights, by the public and academic sectors. With China's rapid economic changes and greater access to information from around the world, societal awareness of animal issues is rising very fast. Hastening this paradigm shift were several highly public incidents involving animal cruelty, including exposés on bear bile harvesting for traditional Chinese medicine, the thousands of dogs rescued from China's meat trade, and the call to boycott shark fin soup and bird nest soup. This article outlines the current status of campaigning by animal advocates in China (specifically the animal rights movement) from three interlinked perspectives: wildlife conservation, companion animal protection, and laboratory animal protection. By reviewing this campaigning, we attempt to present not only the political and social impact of the concept of animal rights, but also the perceptions of, and challenges to, animal rights activities in China.

  3. Using animation to help students learn computer algorithms.

    Catrambone, Richard; Seay, A Fleming

    2002-01-01

    This paper compares the effects of graphical study aids and animation on the problem-solving performance of students learning computer algorithms. Prior research has found inconsistent effects of animation on learning, and we believe this is partly attributable to animations not being designed to convey key information to learners. We performed an instructional analysis of the to-be-learned algorithms and designed the teaching materials based on that analysis. Participants studied stronger or weaker text-based information about the algorithm, and then some participants additionally studied still frames or an animation. Across 2 studies, learners who studied materials based on the instructional analysis tended to outperform other participants on both near and far transfer tasks. Animation also aided performance, particularly for participants who initially read the weaker text. These results suggest that animation might be added to curricula as a way of improving learning without needing revisions of existing texts and materials. Actual or potential applications of this research include the development of animations for learning complex systems as well as guidelines for determining when animations can aid learning.

    Science.gov (United States)

    Xiao, S.

    2012-12-01

    It is often hypothesized that the rise of animals was triggered by an increase in O2 levels in the atmosphere and oceans. However, this hypothesis is remarkably difficult to test, because the timing of animal divergences is poorly resolved, the physiology of early animals is often unknown, estimates of past pO2 levels come with large error bars, and causal relationships between oxygenation and animal evolution are difficult to establish. Nonetheless, existing phylogenetic, paleontological, and geochemical data indicate that the evolution of macroscopic animals and motile macrometazoans with energetically expensive lifestyles may be temporally coupled with ocean oxygenation events in the Ediacaran Period. Thus, it is plausible that ocean oxygenation may have been a limiting factor in the early evolution of macroscopic, complex, and metabolically aggressive animals (particularly bilaterian animals). However, ocean oxygenation and animal evolution were likely engaged in two-way interactions: Ediacaran oxygenation may have initially lifted a physiological barrier for the evolution of animal size, motility, and active lifestyles, but subsequent animal diversification in the Paleozoic may have also changed oceanic redox structures. Viewed in a broader context, the early evolutionary history of animals was contingent upon a series of events, including genetic preparation (developmental genetics), environmental facilitation (oceanic oxygenation), and ecological escalation (Cambrian explosion), but the rise of animals to ecological importance also had important geobiological impacts on oceanic redox structures, sedimentary fabrics, and global geochemical cycles.

    Recent public-opinion polls indicate that Americans have shown a decline in support for animal experimentation, and several reports suggest a relationship between people's knowledge of animal welfare regulations and their attitudes toward animal research. Therefore, this study was designed to assess respondent's knowledge of several provisions in the Animal Welfare Act (AWA) and Animal Welfare Regulations (AWR), and determine whether exposure to elements of this legislation would influence an individual's attitudes toward the use of animals in research. A survey was used to assess knowledge of animal research regulations and attitudes toward animal research from a sample of individuals recruited through Amazon's Mechanical Turk crowdsourcing marketplace. Results from study 1 confirmed the hypothesis that respondents had little knowledge of various federal regulations that govern animal research activities. Data from study 2 revealed that exposure to elements of the AWA and AWR influenced participants' attitudes toward the use of animals in research. These results suggest that providing information to the general public about the AWA and AWR that protect laboratory animals from abuse and neglect may help alleviate concerns about using animals in research settings.

    Clancy, Cornelius J; Cheng, Shaoji; Nguyen, Minh Hong

    2009-01-01

    Animal models are powerful tools to study the pathogenesis of diverse types of candidiasis. Murine models are particularly attractive because of cost, ease of handling, technical feasibility, and experience with their use. In this chapter, we describe methods for two of the most popular murine models of disease caused by Candida albicans. In an intravenously disseminated candidiasis (DC) model, immunocompetent mice are infected by lateral tail vein injections of a C. albicans suspension. Endpoints include mortality, tissue burdens of infection (most importantly in the kidneys, although spleens and livers are sometimes also assessed), and histopathology of infected organs. In a model of oral/esophageal candidiasis, mice are immunosuppressed with cortisone acetate and inoculated in the oral cavities using swabs saturated with a C. albicans suspension. Since mice do not die from oral candidiasis in this model, endpoints are tissue burden of infection and histopathology. The DC and oral/esophageal models are most commonly used for studies of C. albicans virulence, in which the disease-causing ability of a mutant strain is compared with an isogenic parent strain. Nevertheless, the basic techniques we describe are also applicable to models adapted to investigate other aspects of pathogenesis, such as spatiotemporal patterns of gene expression, specific aspects of host immune response and assessment of antifungal agents, immunomodulatory strategies, and vaccines.

    Sea-biological basic knowledge for divers is offered only in special lessons for advanced scuba divers. According to statistics, however, five per cent of the deadly diving accidents are caused by underwater organisms. This number could be reduced to a fraction, by correct behaviour during the dive and after an accident. The most frequent accidents with sea animals during water sports are not by unprovoked shark attacks, which cause six deaths world-wide per year on the average, but turn out with usually well camouflaged sea inhabitants, that do not attack humans, rather by their inadvertence coincidentally get in contact with it. The various defense instruments of the often small, inconspicuous organisms reach from teeth over poison stings, pricks, spines, scalpelles, nettle injections and chemical weapons up to poison arrows. Due to that variety of the maritime life, the most important representatives of its type are explained including severity level of the caused injury or contamination. Both, diagnostic position and therapy possibility are described as follows: 1. Porifera (sponge), 2. Hydrozoa (white weed, yellow flower head), Actinaria (sea anemones), 3. Conidae (cone shells), Tridocna (giant clam), octopoda (octopus), 4. Acanthaster planci (crown of thorns), Echinodea (sea urchins), Holothurioidea (sea cucumber), 5.

    This animation shows the location of the newly discovered planet-like object, dubbed 'Sedna,' in relation to the rest of the solar system. Starting at the inner solar system, which includes the orbits of Mercury, Venus, Earth, and Mars (all in yellow), the view pulls away through the asteroid belt and the orbits of the outer planets beyond (green). Pluto and the distant Kuiper Belt objects are seen next until finally Sedna comes into view. As the field widens the full orbit of Sedna can be seen along with its current location. Sedna is nearing its closest approach to the Sun; its 10,000 year orbit typically takes it to far greater distances. Moving past Sedna, what was previously thought to be the inner edge of the Oort cloud appears. The Oort cloud is a spherical distribution of cold, icy bodies lying at the limits of the Sun's gravitational pull. Sedna's presence suggests that this Oort cloud is much closer than scientists believed.

    Patterson, Edward Ned E

    2013-05-01

    Epileptogenesis is the process by which a normal brain develops into an epileptic brain. There are 3 distinct phases of epileptogenesis-the latent period before seizures occur, the occurrence of recurrent seizures, and in about 30% of patients, the development of refractory epilepsy. Understanding the basic epileptic circuit abnormalities associated with recurrent seizures via aberrations in glutamate, gamma-aminobutyric acid, and ligand- and voltage-gated ion channel activity can help the small-animal practitioner understand the mechanism of action of the antiepileptic drugs currently used for dogs and cats for new-onset and refractory epilepsy. Understanding the latest research results and theories about the pathophysiology of the latent period of epileptogenesis, where recurrent seizures have not yet developed, would help the practitioner understand possible target areas for future treatments to treat epilepsy by preventing it rather than just symptomatically preventing recurrent seizures. The current areas of focus of research on the latent period include neurodegeneration, neurogenesis, axonal sprouting, glial cell activation, invasion of inflammatory cells, angiogenesis, and subclinical alteration of ligand- and receptor-gated ion channels.

    This animation shows how the Large Hadron Collider (LHC) works. The film begins with an aerial view of CERN near Geneva, with outlines of the accelerator complex, including the underground Large Hadron Collider (LHC), 27-km in circumference. The positions of the four largest LHC experiments, ALICE, ATLAS, CMS and LHCb are revealed before we see protons travelling around the LHC ring. The proton source is a simple bottle of hydrogen gas. An electric field is used to strip hydrogen atoms of their electrons to yield protons. Linac 2, the first accelerator in the chain, accelerates the protons to the energy of 50 MeV. The beam is then injected into the Proton Synchrotron Booster (PSB), which accelerates the protons to 1.4 GeV, followed by the Proton Synchrotron (PS), which pushes the beam to 25 GeV. Protons are then sent to the Super Proton Synchrotron (SPS) where they are accelerated to 450 GeV. The protons are finally transferred to the two beam pipes of the LHC. The beam in one pipe circulates clockwise while ...

    Full Text Available Abstract Background Nepal is small in size but rich in bio-cultural diversity. The rugged terrain of the country is home to a number of unique assemblages of fauna, some of which are endemic. Not only faunal resources the country also harbors some very ancient populations whose interrelationship with these diverse faunal resources is very intimate and thus demands scientific study. Animals play important role in both material and spiritual spheres of their life. There are more than hundred groups of such populations in the country and the group Tamang is one of these. The present paper studies Tamang-animal relationships in central Nepal. There is a growing trend of scientific ethnozoological studies all across the globe, but this field is yet in its infancy in Nepal. The country is losing important fauna as well as ancient human cultures at the advent of development processes. As a result, ethnozoological knowledge is also teetering on the brink of extinction. Methods Ethnozoological data were collected by applying different participatory approaches techniques such as semi-structured interviews, participatory rural appraisal, key informant interviews and focus group discussions. Quantitative data were obtained by employing a household level questionnaire survey. Data were collected from the period of September 2004 to August 2005. Most of the animals were identified up to the species level with the help of standard taxonomic keys. Results The Tamang community treasures knowledge on various uses of 41 genera belonging to 28 families. Out of total number of animals, 14.6% belong to the Invertebrate group and the rest to the Vertebrate group. Of the total uses 58% fall in the food and medicinal use category, 16% in the magico-religious use category, 18% in the category of omen indication, and 2% each in the categories such as weather forecasting, trophy, ethnomusical and taboos. Conclusions The Tamang maintain strong ties with animals both at a

The multiplex fluorescent PCR reaction system was optimized. The developed method could successfully detect bovine, goat and sheep-derived materials of 16 animals. The result showed that the real-time PCR can work accurately and efficiently, and can be 100 times as sensitive as conventional PCR of GB/T 20190-2006. Therefore, this method has the potential application for detection of bovine, goat and sheep-derived materials in feed, meat products, milk products, etc.

    Full Text Available Animals have been selected to improve their productivity in order to increase the profitability to the producer. In this scenario, not much attention was given to health traits. As a consequence of that, selection was made for animals with higher production and a shortened productive life. In addition to that, the intense production system used in livestock has forced animals to be exposed to higher pathogen loads, therefore predisposing them to infections. Infectious diseases are known to be caused by micro-organisms that are able to infect and colonize the host, affecting their physiological functions and causing problems in their production and on animal welfare. Even with the best management practices, diseases are still the most important cause of economic losses in the animal industry. In this review article we have addressed the new tools that could be used to select animals to better cope with diseases and pathogens.

  10. Monitoring Animal Well-being

    DEFF Research Database (Denmark)

    Gronskyte, Ruta

    In recent years, animal well-being in industrial slaughterhouses has become a significant concern for consumers, farmers, and meat producers. Different groups have different interpretations of animal well-being. For the majority of consumers, animal well-being is highly influenced by their values...... and experiences. Meat producers are interested in the stress animals endure because it affects meat quality. Pigs that arrive at slaughterhouses are more sensitive than usual for several reasons. In some cases, pigs are transported for long distances. Not all animals are used to transportation. Upon their arrival......, it is common to mix pigs from different farmers in one area. Such mixing can cause fights between pigs, which can lead to additional stress or the animals being harmed. The unfamiliar environment also increases the animals’ stress levels. In some industrial slaughterhouses, up to 62,000 pigs per week...

  11. [Alternatives to animal experimentation v.s. animal rights terrorism].

    Science.gov (United States)

    Kurosawa, Tsutomu Miki

    2008-05-01

    Systematic modern animal experimentation was established by Bernard Claude who wrote "An Introduction to the Study of Experimental Medicine" in 1865. At this point, the public was already asking that the pain and distress of experimental animals be reduced. For this, scientists, William Russell and Rex Burch in 1959 proposed the principles of alternatives to animal experimentation, the "3Rs". Since that time, animal welfare advocates have promoted the 3Rs concept in biomedical research communities. However, cruel animal experiments have continued and there are reports of radical extremists showing their opposition by invasion, arson, theft and even bombing of institutions involved, resulting in killing of the animals. SHAC, one extremist group believed to be animal welfare activitists was recognized as a terrorist group after the 9.11 tragedy in USA and the government viewed their activities very seriously. In 2001, British animal extremists invaded Japanese universities and stole laboratory resources; one individual was arrested and sentenced to prison for three years; Japanese who assisted in the incident were arrested and one was sentenced for one year. In 2006, SHAC USA members were prosecuted and sentenced for up to 6 years for their terrorism activities including arson. We need to consider the background of these activities which are financially supported by animal welfare advocates. The way we, as scientists who conduct such experiments can respond is by promoting alternatives to this experimentation. In Japan, the animal welfare law was revised in 2005 stressing the importance of 3Rs in scientific activities with animals. The promotion of 3Rs should be strengthened in the pharmaceutical community.

    Farm animal welfare and the design of farm buildings and equipment are interrelated. The animals' requirements and preferences should first be estimated and ways in which this can be done are discussed, as are methods of assessment of their environment. Some examples of the influence which housing and equipment design can have are given. Attention is drawn to the difficulties inherent in the assessment of farm animal welfare and the postulation made that the veterinarian is well fitted to carry out such assessments.

    Parodi, André-Laurent

    2009-11-01

    In the 1970s, under pressure from certain sections of society and thanks to initiatives by several scientific research teams, committees charged with improving the conditions of laboratory animals started to be created, first in the United States and subsequently in Europe. This led to the development of an ethical approach to animal experimentation, taking into account new scientific advances. In addition to the legislation designed to provide a legal framework for animal experimentation and to avoid abuses, this ethical approach, based on the concept that animals are sentient beings, encourages greater respect of laboratory animals and the implementation of measures designed to reduce their suffering. Now, all animal experiments must first receive ethical approval--from in-house committees in the private sector and from regional committees for public institutions. Very recently, under the impetus of the French ministries of research and agriculture, the National committee for ethical animal experimentation published a national ethical charter on animal experimentation, setting the basis for responsible use of animals for scientific research and providing guidelines for the composition and functioning of ethics committees. Inspired by the scientific community itself this ethical standardization should help to assuage--but not eliminate--the reticence and hostility expressed by several sections of society.

    Full Text Available The mechanisms of action of probiotic bacteria and their effect in combating digestive disorders in humans and animals has been demonstrated and supported in numerous scientific studies. Probiotic bacteria are used in a wide range of nutritional techniques in order to support the host organism during physiological strain, to reduce stress due to technology and to combat diarrheal syndromes (occurring naturally or pharmacologically induced. Based on a rich bibliographic material, this paper presents the role of probiotic bacteria to equilibrate the beneficial microbial population and in bacterial turnover by stimulating the host immune response via specific secretions (eg. bacteriocins and competitive exclusion of potentially pathogenic germs in the digestive tract (Salmonella, E. coli. In the same context, this review presents the basic studies on the effect of probiotic bacteria in health maintenance for the main species of farm animals: pigs, poultry, cattle and sheep.

    Among the legal aspects the following topics are treated: the definitions of an experimental animal, an animal experiment and alternative methods with special reference to the 3 R's (replacement, reduction and refinement of animal experiments); the qualifications, education and training of researchers and animal technicians; the licence for animal experimentation; the control on animal welfare; the origin and identification of experimental animals; statistical data on the number of experimental animals; ethics committees and their structure and functions in The Netherlands and Flanders. Extrapolation, species specificity and variability are the most important scientific limitations of animal experimentation. After a short historical survey on the man-animal relation, the following ethical aspects are discussed: the instrumental versus intrinsic value of an experimental animal; the hybrid status of the animal; the objectives of animal rights movements; the balance between the human benefit of an animal experiment and the discomfort for the animal; the problem of animal rights and animal suffering and pain.

    2005-01-01

    The issue of human reproductive cloning has recently received a great deal attention in public discourse. Bioethicists, policy makers, and the media have been quick to identify the key ethical issues involved in human reproductive cloning and to argue, almost unanimously, for an international ban on such attempts. Meanwhile, scientists have proceeded with extensive research agendas in the cloning of animals. Despite this research, there has been little public discussion of the ethical issues raised by animal cloning projects. Polling data show that the public is decidedly against the cloning of animals. To understand the public's reaction and fill the void of reasoned debate about the issue, we need to review the possible objections to animal cloning and assess the merits of the anti-animal cloning stance. Some objections to animal cloning (e.g., the impact of cloning on the population of unwanted animals) can be easily addressed, while others (e.g., the health of cloned animals) require more serious attention by the public and policy makers.

    Humans and other mammals are colonized by trillions of microorganisms, most of which reside in the gastrointestinal tract, that provide key metabolic capabilities, such as the biosynthesis of vitamins and AA, the degradation of dietary plant polysaccharides, and the metabolism of orally administered therapeutics. Although much progress has been made by studying the human microbiome directly, comparing the human microbiome with that of other animals, and constructing in vitro models of the human gut, there remains a need to develop in vivo models where host, microbial, and environmental parameters can be manipulated. Here, we discuss some of the initial results from a promising method that enables the direct manipulation of microbial community structure, environmental exposures, host genotype, and other factors: the colonization of germ-free animals with complex microbial communities, including those from humans or other animal donors. Analyses of these resulting "humanized" gut microbiomes have begun to reveal 1) that key microbial activities can be transferred from the donor to the recipient animal (e.g., microbial reduction of cholesterol and production of equol), 2) that dietary shifts can affect the composition, gene abundance, and gene expression of the gut microbiome, 3) the succession of the microbial community in infants and ex-germ-free adult animals, and 4) the biogeography of these microbes across the length of gastrointestinal tract. Continued studies of humanized and other intentionally colonized animal models stand to provide new insight into not only the human microbiome, but also the microbiomes of our animal companions.

  9. SKIN DETECTION OF ANIMATION CHARACTERS

    Kazi Tanvir Ahmed Siddiqui

    2015-02-01

    Full Text Available The increasing popularity of animes makes it vulnerable to unwanted usages like copyright violations and pornography. That’s why, we need to develop a method to detect and recognize animation characters. Skin detection is one of the most important steps in this way. Though there are some methods to detect human skin color, but those methods do not work properly for anime characters. Anime skin varies greatly from human skin in color, texture, tone and in different kinds of lighting. They also vary greatly among themselves. Moreover, many other things (for example leather, shirt, hair etc., which are not skin, can have color similar to skin. In this paper, we have proposed three methods that can identify an anime character’s skin more successfully as compared with Kovac, Swift, Saleh and Osman methods, which are primarily designed for human skin detection. Our methods are based on RGB values and their comparative relations.

  10. Animals in biomedical space research

    Phillips, Robert W.

    The use of experimental animals has been a major component of biomedical research progress. Using animals in space presents special problems, but also provides special opportunities. Rat and squirrel monkeys experiments have been planned in concert with human experiments to help answer fundamental questions concerning the effect of weightlessness on mammalian function. For the most part, these experiments focus on identified changes noted in humans during space flight. Utilizing space laboratory facilities, manipulative experiments can be completed while animals are still in orbit. Other experiments are designed to study changes in gravity receptor structure and function and the effect of weightlessness on early vertebrate development. Following these preliminary animals experiments on Spacelab Shuttle flights, longer term programs of animal investigation will be conducted on Space Station.

    Domesticated animals play an important role in the life of humanity. All these domesticated animals undergo same process, first domesticated from wild animals, then after long time natural and artificial selection, formed various breeds that adapted to the local environment and human needs. In this process, domestication, natural and artificial selection will leave the selection signal in the genome. The research on these selection signals can find functional genes directly, is one of the most important strategies in screening functional genes. The current studies of selection signal have been performed in pigs, chickens, cattle, sheep, goats, dogs and other domestic animals, and found a great deal of functional genes. This paper provided an overview of the types and the detected methods of selection signal, and outlined researches of selection signal in domestic animals, and discussed the key issues in selection signal analysis and its prospects.

    Bassols, Anna; Turk, Romana; Roncada, Paola

    2014-03-01

    A fundamental issue of farm animal welfare is to keep animals clinically healthy, without disease or stress, particularly in intensive breeding, in order to produce safe and quality food. This issue is highly relevant for the food industry worldwide as they are directly linked to public health and welfare. The aim of this review is to explore how proteomics can assess and improve the knowledge useful for the strategic management of products of animal origin. Useful indications are provided about the latest proteomics tools for the development of novel biotechnologies serving the public health. The multivariate proteomics approach provides the bases for the discovery of biomarkers useful to investigate adaptation syndromes and oxidative stress. These two responses represent the milestones for the study of animal welfare. Moreover their implementation in the characterization and standardization of raw materials, process development, and quality and safety control of the final product of animal origin represents the current frontier in official surveillance and tests development.

    2016-01-01

    Migration is a widespread phenomenon among many taxa. This complex behaviour enables animals to exploit many temporally productive and spatially discrete habitats to accrue various fitness benefits (e.g. growth, reproduction, predator avoidance). Human activities and global environmental change represent potential threats to migrating animals (from individuals to species), and research is underway to understand mechanisms that control migration and how migration responds to modern challenges. Focusing on behavioural and physiological aspects of migration can help to provide better understanding, management and conservation of migratory populations. Here, we highlight different physiological, behavioural and biomechanical aspects of animal migration that will help us to understand how migratory animals interact with current and future anthropogenic threats. We are in the early stages of a changing planet, and our understanding of how physiology is linked to the persistence of migratory animals is still developing; therefore, we regard the following questions as being central to the conservation physiology of animal migrations. Will climate change influence the energetic costs of migration? Will shifting temperatures change the annual clocks of migrating animals? Will anthropogenic influences have an effect on orientation during migration? Will increased anthropogenic alteration of migration stopover sites/migration corridors affect the stress physiology of migrating animals? Can physiological knowledge be used to identify strategies for facilitating the movement of animals? Our synthesis reveals that given the inherent challenges of migration, additional stressors derived from altered environments (e.g. climate change, physical habitat alteration, light pollution) or interaction with human infrastructure (e.g. wind or hydrokinetic turbines, dams) or activities (e.g. fisheries) could lead to long-term changes to migratory phenotypes. However, uncertainty remains

    A Finnish physician encounters problems caused by tropical marine animals either during her/his own travelling or while treating travelers who have returned home. Certain species of medusae and cone shells as well as the stings by some fish species are life-threateningly poisonous. A person stung or bitten by any of the most dangerous species must immediately be admitted to the hospital. Foreign material remaining in tissues after stings by echinoderms and spiky fish may cause problems months after the actual injury. The injuries become easily infected, and antimicrobial drug therapy must thus cover gram-negative rod-shaped bacteria as well.

  18. Animations in medical education: You can do it!

    Directory of Open Access Journals (Sweden)

    Manvikar Purushottam Rao

    2012-01-01

    Full Text Available Introduction: Animations are the best suited to convey and create an impact of an idea or concept in media business. Animations are sequential frames of pictures shown across this fourth dimension, namely "time." Cartoons are the best examples of animations; needless to say, animations grab the attentions of every one. Animations can also be effectively used in medical education especially in teaching human embryology. It communicates of a concept of three-dimensional structures against one more dimension, namely time. However, to create a module of animation, knowledge, and operative skills of animation software like Flash® , Author ware® , Macromedia® or other high-ended software is necessary. Aim: To design simple, user-friendly and easy to make an effective animation using one of the office tools of Windows® , Power Point® . Materials and Methods: A personal computer with following configuration was used. Pentium III processor with 1.3 Gz speed, 40 GB HDD, 128 MB RAM, with multimedia kit, key pad, and scroll mouse was used. Programs used were Power Point® and MS Paint® . A screen play of sequences of diagrams was written. Frames consisting of diagrams of stages of development were drawn in MS Paint® , and were pasted in PowerPoint slides and animation tool was applied. Previewing was done at every stage. Results: Stages of development of storyboard have been shown as print screen images, 1-6. Conclusion: Emphasis is that such simple animations can be easily made. It is cheap and does not require any sophisticated software. However, it is time consuming but can be taken up as phased assignments or can be given as undergraduate student projects. This will certainly help to build teaching material in the department.

  1. Refining animal experiments: the first Brazilian regulation on animal experimentation.

    Science.gov (United States)

    de A e Tréz, Thales

    2010-06-01

    The very first law on animal experimentation has been approved recently in Brazil, and now is part of a set of the legal instruments that profile the Brazilian government's attitude toward the use of animals in experiments. Law 11794/08 establishes a new legal instrument that will guide new methods of conduct for ethics committees, researchers and representatives of animal protection societies. This comment aims to analyse critically the implications that this law brings to Brazilian reality. The link between it and the Russell and Burch's Three Rs concept is defined, and certain problems are identified. The conclusion is that the body of the law emphasises the refinement of animal experiments, but gives little importance to the principles of reduction and replacement.

  2. Storytelling through animation: Oxford Sparks

    Pyle, D. M.; Cook, A.

    2013-12-01

    Oxford Sparks is a portal that launched in 2012, with the aim of bringing together resources that have been created across the University of Oxford and elsewhere for the purpose of wider engagement with science. To bring attention to this site, Oxford Sparks developed a set of high-quality short animations, each designed to tell a story relating to a current area of science. These animations have been launched on YouTube, and will shortly be available on iTunesU, and have covered broad areas of science from subduction zones (';Underwater Volcano Disaster'), through the early history of the solar system (';Rogue Planet') to the workings of the Large Hadron Collider (';A quick look around the LHC'). The animations have each been developed in close collaboration with researchers, created by a team with experience of education, engagement and outreach. The two minute scripts are intended to be both widely accessible and viewable as ';stand alone' stories. To this end, the scripts are humorous; while the animations are delightfully quirky, and created by professional animator with a degree-level science background. The animations are also intended to be used as ';lesson starters' in school, and educational activities graded for different age groups are being developed in parallel with the animations. They have been used, successfully, on pre-university summer schools, and in university classes. We are gathering both quantitative (analytics) and qualitative (school teacher and student focus group) feedback to monitor the success of the project, and to understand the strengths and weaknesses of the approach. In the first year since launch, Oxford Sparks animations were viewed over 80,000 times on YouTube, in part due to the surge of interest in the Large Hadron Collider animation after the discovery of the Higgs Boson.

    Boxley, Chett; McKelvie, Jessica

    2012-08-28

    An animal litter composition including geopolymerized ash particulates having a network of repeating aluminum-silicon units is described herein. Generally, the animal litter is made from a quantity of a pozzolanic ash mixed with a sufficient quantity of water and an alkaline activator to initiate a geopolymerization reaction that forms geopolymerized ash. After the geopolymerized ash is formed, it is dried, broken into particulates, and sieved to a desired size. These geopolymerized ash particulates are used to make a non-clumping or clumping animal litter. Odor control is accomplished with the addition of a urease inhibitor, pH buffer, an odor eliminating agent, and/or fragrance.

  5. The question of animal culture.

    1992-06-01

    In this paper I consider whether traditional behaviors of animals, like traditions of humans, are transmitted by imitation learning. Review of the literature on problem solving by captive primates, and detailed consideration of two widely cited instances of purported learning by imitation and of culture in free-living primates (sweet-potato washing by Japanese macaques and termite fishing by chimpanzees), suggests that nonhuman primates do not learn to solve problems by imitation. It may, therefore, be misleading to treat animal traditions and human culture as homologous (rather than analogous) and to refer to animal traditions as cultural.

    2000-09-01

    Several arguments are raised attributing to aeroallergens an important role in atopic dermatitis. The aeroallergens that penetrate the epidermis could be fixed by IgE on the Langerhans cells and then induce a cellular mediator reaction comparable to that of allergic contact eczema. Patch tests have been developed to evaluate the role of aeroallergens (dust mites, animal dander, etc.). Preventive anti-dust mites measures in the home of atopic patients are recommended. Eviction of domestic animals (cat, dog, etc.) or avoidance measures for animal dander in the home can produce improvement in atopic dermatitis. Oral specific immunotherapy is being validated as a treatment for this disease.

    2013-10-01

    Optogenetics is the optical control of neuronal excitability by genetically delivered light-activated channels and pumps and represents a promising tool to fuel the study of circuit function in psychiatric animal models. This review highlights three developments. First, we examine the application of optogenetics in one of the neuromodulators central to the pathophysiology of many psychiatric disorders, the dopaminergic system. We then discuss recent work in translating functional magnetic resonance imaging in small animals (in which optogenetics can be employed to reveal physiological mechanisms underlying disease-related alterations in brain circuits) to patients. Finally, we describe emerging technological developments for circuit manipulation in freely behaving animals.

  11. A brave new animal for a brave new world: The British Laboratory Animals Bureau and the constitution of international standards of laboratory animal production and use, circa 1947-1968.

    Science.gov (United States)

    Kirk, Robert G W

    2010-03-01

    In 1947 the Medical Research Council of Britain established the Laboratory Animals Bureau in order to develop national standards of animal production that would enable commercial producers better to provide for the needs of laboratory animal users. Under the directorship of William Lane-Petter, the bureau expanded well beyond this remit, pioneering a new discipline of "laboratory animal science" and becoming internationally known as a producer of pathogenically and genetically standardized laboratory animals. The work of this organization, later renamed the Laboratory Animals Centre, and of Lane-Petter did much to systematize worldwide standards for laboratory animal production and provision--for example, by prompting the formation of the International Committee on Laboratory Animals. This essay reconstructs how the bureau became an internationally recognized center of expertise and argues that standardization discourses within science are inherently internationalizing. It traces the dynamic co-constitution of standard laboratory animals alongside that of the identities of the users, producers, and regulators of laboratory animals. This process is shown to have brought into being a transnational community with shared conceptual understandings and material practices grounded in the materiality of the laboratory animal, conceived as an instrumental technology.

    A process for forming a surface-treatment layer on an electroactive material includes heating the electroactive material and exposing the electroactive material to a reducing gas to form a surface-treatment layer on the electroactive material, where the surface-treatment layer is a layer of partial reduction of the electroactive material.

  13. [Poultry husbandry and animal health].

    Science.gov (United States)

    Neumann, U

    2003-08-01

    Close interactions are existing between poultry husbandry and poultry health. The more housing systems and the environment of the animals can be controlled, the less the general risk of disorders in poultry flocks--especially of diseases which are caused by the introduction of microoganisms. Resulting deterimental effects will affect not only the animals themselves, but also pose a risk indirectly for humans via food originating from animals under production. Also, by keeping the risk of infections as low as possible, the use of therapeutics can be avoided. This will reduce the risk of residues in food of animal origin. In summary, with all probability open poultry husbandry systems, especially those including free range systems pose increased risks for poultry health and consequently for the quality of food originating from poultry production. At least, those systems require highest standards of biosecurity, defined as management, location, farm layout, cleaning and desinfection incl. pest control programs, immunization and specific veterinary monitoring concepts to prevent infections.

  14. Animal studies of addictive behavior.

    Science.gov (United States)

    Vanderschuren, Louk J M J; Ahmed, Serge H

    2013-04-01

    It is increasingly recognized that studying drug taking in laboratory animals does not equate to studying genuine addiction, characterized by loss of control over drug use. This has inspired recent work aimed at capturing genuine addiction-like behavior in animals. In this work, we summarize empirical evidence for the occurrence of several DSM-IV-like symptoms of addiction in animals after extended drug use. These symptoms include escalation of drug use, neurocognitive deficits, resistance to extinction, increased motivation for drugs, preference for drugs over nondrug rewards, and resistance to punishment. The fact that addiction-like behavior can occur and be studied in animals gives us the exciting opportunity to investigate the neural and genetic background of drug addiction, which we hope will ultimately lead to the development of more effective treatments for this devastating disorder.

    Kind, Alexander; Schnieke, Angelika

    2008-12-01

    Since its inception 20 years ago, the animal pharming industry has promoted transgenic animals as a cost-effective method of biopharmaceutical production. However, it took until 2006 for the first therapeutic product to gain regulatory approval. This was an important milestone, but scepticism still abounds. Can pharming regain investor confidence, and will society accept transgenic livestock as a production method? There is some cause for optimism, biopharmaceuticals are a large, expanding market and animal pharming has already made considerable strides. A novel production platform has been established, groundbreaking technologies developed, a necessary regulatory framework put in place. Nevertheless, despite cost advantages, pharming has become a niche production method and its long term success may depend on products unique to transgenic animals.

    Animal domestication has far-reaching significance for human society. The sequenced genomes of domesticated animals provide critical resources for understanding the genetic basis of domestication. Various genomic analyses have shed a new light on the mechanism of artificial selection and have allowed the mapping of genes involved in important domestication traits. Here, we summarize the published genomes of domesticated animals that have been generated over the past decade, as well as their origins, from a phylogenomic point of view. This review provides a general description of the genomic features encountered under a two-stage domestication process. We also introduce recent findings for domestication traits based on results from genome-wide association studies and selective-sweep scans for artificially selected genomic regions. Particular attention is paid to issues relating to the costs of domestication and the convergent evolution of genes between domesticated animals and humans.

    In this paper, we propose a pose editing and animation method for triangulated surfaces based on a user controlled partitioning of the model into deformable parts and rigid parts which are denoted handles. In our pose editing system, the user can sculpt a set of poses simply by transforming...... the handles for each pose. Using Laplacian editing, the deformable parts are deformed to match the handles. In our animation system the user can constrain one or several handles in order to define a new pose. New poses are interpolated from the examples poses, by solving a small non-linear optimization...... problem in order to obtain the interpolation weights. While the system can be used simply for building poses, it is also an animation system. The user can specify a path for a given constraint and the model is animated correspondingly....

    2015-11-01

    Cerebral ischemia remains one of the most frequent causes of death and disability worldwide. Animal models are necessary to understand complex molecular mechanisms of brain damage as well as for the development of new therapies for stroke. This review considers a certain range of animal models of cerebral ischemia, including several types of focal and global ischemia. Since animal models vary in specificity for the human disease which they reproduce, the complexity of surgery, infarct size, reliability of reproduction for statistical analysis, and adequate models need to be chosen according to the aim of a study. The reproduction of a particular animal model needs to be evaluated using appropriate tools, including the behavioral assessment of injury and non-invasive and post-mortem control of brain damage. These problems also have been summarized in the review.

    We posit a new geometric perspective to define, detect, and classify inherent patterns of collective behaviour across a variety of animal species. We show that machine learning techniques, and specifically the isometric mapping algorithm, allow the identification and interpretation of different types of collective behaviour in five social animal species. These results offer a first glimpse at the transformative potential of machine learning for ethology, similar to its impact on robotics, where it enabled robots to recognize objects and navigate the environment.

    Livestock animals have made a significant contribution to human health and well-being throughout humankind's history. A significant contribution of farm animals to human health are the longstanding use of bovine and porcine for production of insulin (for treatment of diabetes), gelatin (for pharmaceutical and other purposes), as well as horse and sheep antibody against natural venoms, toxins, drugs and microbial peptides. Gelatin being the biggest animal protein consumed in human health, follows with antibodies fragments. The chronic problem of animal-derived therapeutics, especially those of high molecular weight, is the immunogenicity induction in addition to their biosafety. However, the invertebrates and lower vertebrates donate the human being a several crucial emergency saving life small-peptides or their analogs such as Refludan, Prialt, Exendin. Not only, but the farm animals are enormously using as models for novel surgical strategies, testing of biodegradable implants and sources of tissue replacements, such as skin and heart valves. Recently, they are being harnessing as bioreactor for production of biopharmaceutical related products through gene farming with efficiency far greater than any conventional microbial or cell-culture production systems. Only 16 transgenic cows would be covering the worldwide needs from human growth hormone. The transgenic, especially animal, technology would be solving a several biopharmaceutical products disadvantages, such as cost, biosafety, immunogenicity and the availability dimensions.

The products which have been taken into account were live animals and animal products. Thus, we have made an analyse on the Romanian imports and exports at the global level and at the European level. Focused on the animal products, on the global level, there were registered major differences during the first seven years in the analysed period. Breaking by branches, we have pointed out huge distinctions between imports and exports, where the balance of trade was completely negative. Meanwhile, to have a good view on the international trade there were made links, based on some indexes between imports, exports, GDP and investments.

    Science.gov (United States)

    Palley, Lori S; O'Rourke, P Pearl; Niemi, Steven M

    2010-01-01

    The term animal-assisted therapy (AAT) commonly refers to the presentation of an animal to one or more persons for the purpose of providing a beneficial impact on human health or well-being. AAT is an ideal example of "One Health" because of numerous studies and widespread testimonials indicating that many humans feel better in the presence of pets and other domesticated animals, and, conversely, that some of those creatures appear to respond positively to human company for their emotional and perhaps physical betterment. Many AAT studies have claimed a wide range of human health benefits, but much of the research is characterized by small-scale interventions among disparate fields, resulting in criticisms about weak study design or inconsistent methodology. Such criticisms contrast with the strongly held belief among many that interaction with friendly animals has a strong and innate value for the persons involved. Consequently the appeal of AAT in human medicine today may be generally characterized as a "push" by enthusiastic advocates rather than a "pull" by prescribing physicians. To fully integrate AAT into conventional medical practice as an accepted therapeutic modality, more convincing intervention studies are necessary to confirm its clinical merits, along with an understanding of the underlying mechanism of the human response to the company of friendly animals.

  13. Animal models for auditory streaming.

    Science.gov (United States)

    Itatani, Naoya; Klump, Georg M

    2017-02-19

    Sounds in the natural environment need to be assigned to acoustic sources to evaluate complex auditory scenes. Separating sources will affect the analysis of auditory features of sounds. As the benefits of assigning sounds to specific sources accrue to all species communicating acoustically, the ability for auditory scene analysis is widespread among different animals. Animal studies allow for a deeper insight into the neuronal mechanisms underlying auditory scene analysis. Here, we will review the paradigms applied in the study of auditory scene analysis and streaming of sequential sounds in animal models. We will compare the psychophysical results from the animal studies to the evidence obtained in human psychophysics of auditory streaming, i.e. in a task commonly used for measuring the capability for auditory scene analysis. Furthermore, the neuronal correlates of auditory streaming will be reviewed in different animal models and the observations of the neurons' response measures will be related to perception. The across-species comparison will reveal whether similar demands in the analysis of acoustic scenes have resulted in similar perceptual and neuronal processing mechanisms in the wide range of species being capable of auditory scene analysis.This article is part of the themed issue 'Auditory and visual scene analysis'.

    @@ 1 Technology of natural materials Early man used conveniently shaped stones as tools."Workshop" areas have been found with large numbers of stones, some showing signs of being worked[1].However, organic materials like wood will decay under normal wet conditions in the presence of oxygen, so we won't find the same sort of evidence for wooden tools. It is safe to assume that early man used sticks as probes and clubs, and maybe even for making some sort of nestlike protection against the elements and predators, since we see chimpanzees and other animals doing this sort of thing. So wood, and almost certainly other plant materials such as fibrous leaves, and bone and other materials gleaned from dead animals, would be used from the earliest times. We need to know this in order to establish the idea that Man can be expected to have a long history of the use and manipulation of natural materials. This needs skills in choosing materials for certain uses on the basis of their mechanical properties,whether those properties are to do with the ease of shaping the material or the effectiveness of that material in use. Occasionally the material was chosen simply because it was readily available. If we find that a particular material was always used for a certain job, it's reasonable to deduce that Man was exerting materials selection criteria through experience.

    Despite growing academic interest in the human–animal relationship, little research has been directed toward the political regulation of animal treatment. Even less attention has been accorded to the emergence of the long dominant paradigm in this policy area, namely, the ideology of animal welfare. This book attempts to address this gap by chronicling the early history of animal politics in Sweden with the aim of producing a critical, deconstructive genealogy of animal cruelty and animal wel...

    2005-01-01

    Singer's utilitarian and Regan's deontological views must be rejected because: (1) they rely on criteria for moral standing that can only be known a priori and (2) if these criteria were successful, they'd be too restrictive. I hold that while mental properties may be sufficient for moral standing, they are not necessary. (3) Their criteria of moral standing do not unambiguously abrogate needless harm to animals. I defend a theory of biocentric individualism that upholds the principle of species egalitarianism while at the same time recognizing that in certain cases, human needs must outweigh the needs of non-humans. On this view, moral consideration is not conferred only on beings that have human-life mental properties. Finally, it offers an unambiguous recommendation for the abolition of harmful animal experimentation, factory farming, and killing animals for sport.

    Full Text Available In last decade, Romanian agriculture does not follow entirely the European and programs as concerns land exploitation and animal farming (SAPARD. Restrictive development projects (POS-MEDIU, POS-DRU, POS-CCE were active only in large private farms, which represent only 10.7% of the total registered farms in Romania. Was used a questionnaire for 36 students of our faculty, which have animal farms in 7 counties in Northwest of Transylvania. The study want to put into evidence the current problems of farmers in conditions of some private farms with small and middle number of animals. As small farms, they do not obtain important productions because of financial resource absence, limited professional education and absence of association in bigger exploitation farms. In these situations, the government must react providing a legal frame for rural agricultural development, supporting and supervising these small exploitations.

    A critical concern with respect to marine animal acoustics is the issue of hearing "sensitivity," as it is widely used as a criterion for the onset of noise-induced effects. Important aspects of research on sensitivity to sound by marine animals include: uncertainties regarding how well these species detect and respond to different sounds; the masking effects of man-made sounds on the detection of biologically important sounds; the question how internal state, motivation, context, and previous experience affect their behavioral responses; and the long-term and cumulative effects of sound exposure. If we are to better understand the sensitivity of marine animals to sound we must concentrate research on these questions. In order to assess population level and ecological community impacts new approaches can possibly be adopted from other disciplines and applied to marine fauna.

    Full Text Available This paper presents a bi-constructivist approach to the study of animal life, which is opposed to the realist-Cartesian paradigm in which most ethology operates. The method is elaborated through the examples of a knot-tying orangutan in a Paris zoo and chile-eating cats in a New York apartment. We show that, when grounded in the operational framework of the phenomenological approach, the interpretation of animal life acquires a much more robust character than is usually supposed.

    Animal models have allowed detailed study of hemodynamic alterations typical of portal hypertension and the molecular mechanisms involved in abnormalities in splanchnic and systemic circulation associated with this syndrome. Models of prehepatic portal hypertension can be used to study alterations in the splanchnic circulation and the pathophysiology of the hyperdynamic circulation. Models of cirrhosis allow study of the alterations in intrahepatic microcirculation that lead to increased resistance to portal flow. This review summarizes the currently available literature on animal models of portal hypertension and analyzes their relative utility. The criteria for choosing a particular model,depending on the specific objectives of the study, are also discussed.

    Full Text Available Many paradigmatic forms of animal rights and environmental activism have been classed as terrorism both in popular discourse and in law. This paper argues that the labelling of many violent forms of direct action carried out in the name of animal rights or environmentalism as ‘terrorism’ is incorrect. Furthermore, the claim is also made that even those acts which are correctly termed as terrorism are not necessarily wrongful acts. The result of this analysis is to call into question the terms of public debate and the legitimacy of anti-terrorism laws targeting and punishing radical activism.

    Full Text Available This study aims to investigate the process of animated video creation by pre-service science teachers and analyze their opinions about how this technology can be used for science instruction. Fifteen pre-service science teachers participated in this study. During the study, students learned how to prepare animated videos using GoAnimate program, then they were required to prepare their own animations related to their middle school science subjects. This research is designed as a qualitative case study. Sample of the study was selected using criterion and easily accessible sampling methods to determine the participants. The data was collected through the face-to-face individual interviews. A semi-structured interview form that contains the questions related with the animated video creation process and pre-service teachers’ opinions about this technology has been prepared by the researchers. The duration of the interviews was around 15 minutes. Content analysis was used for the data analysis. According to the findings: the pre-service science teachers who participated in the study did not have any prior experience with animation technology, they had some difficulties to use this technology for the first time; most of them stated that animated videos would be engaging and could be endearing, but they had concerns about that students would be more interested in visuals instead of deeper understanding; they perceived animated videos being more helpful for middle school level and also suggested GoAnimate should have more characters available for science animations. In line with the research findings, several suggestions were given for the use of visual materials in science education.

  19. [Animal health and primary health care].

    Science.gov (United States)

    Moro, M

    1983-01-01

    As part of the primary care strategy, the Governments of the Americas have included the agricultural and animal health sectors among the public health activities of the Plan of Action. This means that both sectors--agricultural and veterinary--must be guided in their work by a multidisciplinary and multisectoral approach, with full community participation. Hence, it is certain that both the study of veterinary medicine and the practice of the profession in the Region will have to be reoriented so that they may be more fully integrated with the primary care strategy. The reorientation of animal health activities is the subject of this paper. There can be no doubt that animal health has a vital part to play in improving the quality of human life and that veterinary practice itself offers excellent opportunities for building a sense of personal and community responsibility for the promotion, care, and restoration of health. Through their contact with the rural population while caring for their livestock (an integral part of the rural socioeconomic structures), the veterinarian and animal health assistant establish close bonds of trust not only with farmers, but with their families and the entire community as well; they are thus well placed to enlist community participation in a variety of veterinary public health activities such as zoonoses control, hygiene programs, and so forth. While the goal of the Plan of action is to extend primary care to the entire population, the lack of material and human resources requires that priority attention be given to the needs of the more vulnerable groups, including the extremely poor living in rural and urban areas. These are the groups at greatest risk from the zoonoses still present in the Americas. In the face of these facts, it is clear that primary care in the animal health field should be based on the application in each country of proven, effective, appropriate technology by personnel who, whether new or retrained, are well

  17. Animal Models for Periodontal Disease

    Directory of Open Access Journals (Sweden)

    Helieh S. Oz

    2011-01-01

    Full Text Available Animal models and cell cultures have contributed new knowledge in biological sciences, including periodontology. Although cultured cells can be used to study physiological processes that occur during the pathogenesis of periodontitis, the complex host response fundamentally responsible for this disease cannot be reproduced in vitro. Among the animal kingdom, rodents, rabbits, pigs, dogs, and nonhuman primates have been used to model human periodontitis, each with advantages and disadvantages. Periodontitis commonly has been induced by placing a bacterial plaque retentive ligature in the gingival sulcus around the molar teeth. In addition, alveolar bone loss has been induced by inoculation or injection of human oral bacteria (e.g., Porphyromonas gingivalis in different animal models. While animal models have provided a wide range of important data, it is sometimes difficult to determine whether the findings are applicable to humans. In addition, variability in host responses to bacterial infection among individuals contributes significantly to the expression of periodontal diseases. A practical and highly reproducible model that truly mimics the natural pathogenesis of human periodontal disease has yet to be developed.

    The Act on Nature Conservation of 16.04.2004 (Official Journal, 2004, No 92, item 880) imposes on private individuals the duty to register some animals. The data collected by Kraków municipal authorities and delivered to the Poison Information Centre (Colleglum Medicum, Jagiellonian University) indicate that there are following species in private hands in the city and its surroundings: 11 individuals of Naja naja, 2--Hydrodynates gigas and 55-- Dendrobates spp. According to these information the employees of the PIC elaborated the advice on the treatment of specific animals' poisoning. In the period May 2003 - May 2004 (before the above Act came into force) there were 143 individuals from Brachypelma genus and 3 scorpions (Pandinus imperator) registered in Krakow. These species produce venoms which take local effect. According to art. 64 (1) of the above Act it is compulsory to register amphibians, reptiles, birds and mammals. However, it would be desirable to introduce the duty to register also dangerous species of invertebrates and fishes. It would provide the complete list of poisonous animals kept in private hands. Thus, it would be possible to estimate any possible threats and to elaborate adequate treatment in case of specific animals' poisoning.

  1. Artificial cloning of domestic animals.

    Science.gov (United States)

    Keefer, Carol L

    2015-07-21

    Domestic animals can be cloned using techniques such as embryo splitting and nuclear transfer to produce genetically identical individuals. Although embryo splitting is limited to the production of only a few identical individuals, nuclear transfer of donor nuclei into recipient oocytes, whose own nuclear DNA has been removed, can result in large numbers of identical individuals. Moreover, clones can be produced using donor cells from sterile animals, such as steers and geldings, and, unlike their genetic source, these clones are fertile. In reality, due to low efficiencies and the high costs of cloning domestic species, only a limited number of identical individuals are generally produced, and these clones are primarily used as breed stock. In addition to providing a means of rescuing and propagating valuable genetics, somatic cell nuclear transfer (SCNT) research has contributed knowledge that has led to the direct reprogramming of cells (e.g., to induce pluripotent stem cells) and a better understanding of epigenetic regulation during embryonic development. In this review, I provide a broad overview of the historical development of cloning in domestic animals, of its application to the propagation of livestock and transgenic animal production, and of its scientific promise for advancing basic research.

    Full Text Available This essay presents a reading of Nietzsche’s second Untimely Consideration and the second essay of his On the Genealogy of Morals that reevaluates the importance of animal forgetfulness in Nietzsche’s conception of history and politics. On my account the insight in the value of animal forgetfulness allows Nietzsche to redefine memory as an artistic force, and historiography as an art of interpretation. This article relates this insight to the relation between politics and the promise in the second essay of On the Genealogy of Morals, arguing that here the rediscovery of the value of animal forgetfulness allows Nietzsche to redefine politics as a realm in which the animality of the human being can take on a creative and productive role exemplified by the promise of the sovereign individual instead of being considered as an object of domination.Este ensayo presenta una lectura de la segunda Consideración intempestiva y del segundo ensayo de La genealogía de la moral que revaloriza la importancia del olvido animal en la concepción de la historia y de la política propuesta por Nietzsche. En mi interpretación, el reconocimiento del valor del olvido animal permite a Nietzsche redefinir la memoria como una fuerza artística y la historiografía como un arte de la interpretación. Este artículo conecta esta intuición con la relación entre política y promesa establecida por Nietzsche en el segundo ensayo de La genealogía de la moral, argumentando que el descubrimiento del valor del olvido animal permite a Nietzsche redefinir la esfera de la política como una esfera en la cual la animalidad del ser humano pude tomar un rol creativo y productivo ejemplificado por la promesa del individual soberano en vez de ser considerado como un objeto de dominación y explotación.

    An intercomparison study was conducted to determine the presence of processed animal proteins (PAPs), including meat and bone meal (MBM) from various species, in animal feed. The performances of different methods, such as microscopy, polymerase chain reaction (PCR), immunoassays, and a protocol based on iquid chromatography (LC), were compared. Laboratories were asked to analyze for PAPs from all terrestrial animals and fish (total PAPs); mammalian PAPs; ruminant PAPs; and porcine PAPs. They were free to use their method of choice. In addition, laboratories using microscopy were asked to determine the presence of PAPs from terrestrial animals, which is applicable only to microscopy. For total PAPs microscopy, LC and some immunoassays showed sufficient results at a concentration as low as 0.1% MBM in the feed. In contrast, PCR was not fit for purpose. In differentiating between MBM from terrestrial animals and fishmeal, microscopy detected 0.5% of terrestrial MBM in feed in the presence of 5% fishmeal, but was less successful when the concentration of MBM from terrestrial animals was 0.1%. The animal-specific determination of MBM from mammals or, more specifically from either ruminants or pigs, by PCR showed poor results, as indicated by a high number of false-positive and false-negative results. The only PCR method that scored quite well was applied by a member of the organizer team of the study. Immunoassays scored much better than PCR, showing sufficient sensitivity but some deficiency in terms of specificity. The results also demonstrated that the reliable determination of MBM from ruminants has not been resolved, especially for low concentrations of MBM (0.1%) in feed. Comparison of the results for mammalian MBM from all methods indicated that, for control purposes, the immunoassay method, especially when applied as dipsticks, could be used as a rapid screening method combined with microscopy to confirm the positive samples. However, implementation of such a

  6. Analytic Materials

    The theory of inhomogeneous analytic materials is developed. These are materials where the coefficients entering the equations involve analytic functions. Three types of analytic materials are identified. The first two types involve an integer $p$. If $p$ takes its maximum value then we have a complete analytic material. Otherwise it is incomplete analytic material of rank $p$. For two-dimensional materials further progress can be made in the identification of analytic materials by using the well-known fact that a $90^\\circ$ rotation applied to a divergence free field in a simply connected domain yields a curl-free field, and this can then be expressed as the gradient of a potential. Other exact results for the fields in inhomogeneous media are reviewed. Also reviewed is the subject of metamaterials, as these materials provide a way of realizing desirable coefficients in the equations.

    Full Text Available The stories lives tell, the narratives they follow and the spaces they embody are critical to articulating the conditions of everyday life. This resonates in the fraught relations within and between surf cultures, affluent societies and economic development. In the context of Rural Cultural Studies the analysis of coastal place allows for a combination of self-reflexive, critical and transformative modes of inquiry. This pedagogy of the coast offers innovative approaches to contemporary anthropogenic and existential challenges. For the Ecological Humanities, adjusting to living synergistically requires dialogue, ethical frameworks and care. This includes attention to the more-than human world and the non-human inhabitants with whose lives people become entangled in the mutuality of wandering paths and shared haunts. The imaginary-material architectures and geographies of these samples of coastal life, are topographies woven of spatiality and contemporary coastal writing. These contemplations attempt to sketch performative interactions from the auto-choreography animating sentient archives.

    Lignocellulosic material is the most abundant renewable resource in the earth. Herbivores and wood-eating insects are highly effective in the digestion of plant cellulose, while anaerobic digestion process simulating animal alimentary tract still remains inefficient. The digestion mechanisms of herbivores and wood-eating insects and the development of anaerobic digestion processes of lignocellulose were reviewed for better understanding of animal digestion mechanisms and their application in design and operation of the anaerobic digestion reactor. Highly effective digestion of lignocellulosic materials in animal digestive system results from the synergistic effect of various digestive enzymes and a series of physical and biochemical reactions. Microbial fermentation system is strongly supported by powerful pretreatment, such as rumination of ruminants, cellulase catalysis and alkali treatment in digestive tract of wood-eating insects. Oxygen concentration gradient along the digestive tract may stimulate the hydrolytic activity of some microorganisms. In addition, the excellent arrangement of solid retention time, digesta flow and end product discharge enhance the animal digestion of wood cellulose. Although anaerobic digestion processes inoculated with rumen microorganisms based rumen digestion mechanisms were developed to treat lignocellulose, the fermentation was more greatly limited by the environmental conditions in the anaerobic digestion reactors than that in rumen or hindgut. Therefore, the anaerobic digestion processes simulating animal digestion mechanisms can effectively enhance the degradation of wood cellulose and other organic solid wastes.

    No previous analytical procedures are available and validated for mercury speciation analysis in terrestrial animal tissues. This analysis is a difficult task both because the expected concentrations are low, since important accumulation process are not likely to occur, and also because there are not commercially available certified reference material. Thus, an analytical methodology has been developed and validated for mercury speciation for the specific case of terrestrial animal tissues. The proposed method is based on the quantitative extraction of the species by closed-vessel microwave assisted heating with an alkaline reagent, followed by ethylation. The ethylated derivatives were then submitted to head-space solid phase microextraction with a 100 μm polidimethylsiloxane-coated fiber, and desorbed onto a gas chromatograph coupled to atomic fluorescence detection via pyrolysis unit (HS-SPME-GC-pyro-AFS). Procedural detection limits were 31.8 ng g(-1) and 52.5 ng g(-1) for CH(3)Hg(+) and Hg(2+), respectively, for liver and 35.3 ng g(-1) and 58.1 ng g(-1) for CH(3)Hg(+) and Hg(2+), respectively, for kidney. These limits of detection are 5.5 and 6 times better than the obtained without solid phase microextraction for CH(3)Hg(+) and Hg(2+), respectively. The methodology was found linear up to 120 μg L(-1) and reproducible from one day to the following. It was validated with certified reference materials NCS ZC 71001 (beef liver) and BCR No 186 (pig kidney) for total mercury, calculated as the sum of species, and with spiked red deer liver and kidney for speciation. Finally, it was applied to the analysis of samples of red deer liver, red deer kidney and wild boar kidney coming from the Almadén's mercury mining area (Ciudad Real, Spain), the longest and largest producer of mercury in the world until its closure in 2002.

    2001-05-02

    Substrate vibration has been important to animals as a channel of communication for millions of years, but our literature on vibration in this context of biologically relevant information is only decades old. The jaw mechanism of the earliest land vertebrates allowed them to perceive substrate vibrations as their heads lay on the ground long before airborne sounds could be heard. Although the exact mechanism of vibration production and the precise nature of the wave produced are not always understood, recent development of affordable instrumentation to detect and measure vibrations has allowed researchers to answer increasingly sophisticated questions about how animals send and receive vibration signals. We now know that vibration provides information used in predator defense, prey detection, recruitment to food, mate choice, intrasexual competition, and maternal/brood social interactions in a variety of insect orders, spiders, crabs, scorpions, chameleons, frogs, golden moles, mole rats, kangaroos rats, wallabies, elephants and bison.

    Full Text Available Few recent advances have revolutionized the developmental biology as the animal cloning has. Since the birth of Dolly, the sheep, in 1996, which was the first derived clone of a mature animal, a new scientific era began. It has been characterized by growing demystification that differentiated cells are unalterable entities in its nuclear organization and chromatin structure, and by a better understanding of the mechanisms that regulate the development. Throughout this paper, we will review some of the achievements and limitations of the techniques used, both in therapeutic and in the reproductive cloning, as well as the perspectives that its application allows to glimpse within a close future. At the same time, we will point out some considerations regarding the ethical debate that surrounds such a controversial issue.

    Revealing the sketching sequence of a line drawing can be visually intriguing and used for video-based storytelling. Typically this is enabled based on tedious recording of artists\\' drawing process. We demonstrate that it is often possible to estimate a reasonable drawing order from a static line drawing with clearly defined shape geometry, which looks plausible to a human viewer. We map the key principles of drawing order from drawing cognition to computational procedures in our framework. Our system produces plausible animated constructions of input line drawings, with no or little user intervention. We test our algorithm on a range of input sketches, with varying degree of complexity and structure, and evaluate the results via a user study. We also present applications to gesture drawing synthesis and drawing animation creation especially in the context of video scribing.

    Full Text Available The prevalence of neurodegenerative diseases, such as Alzheimer's disease (AD and Parkinson's disease (PD, increases with age, and the number of affected patients is expected to increase worldwide in the next decades. Accurately understanding the etiopathogenic mechanisms of these diseases is a crucial step for developing disease-modifying drugs able to preclude their emergence or at least slow their progression. Animal models contribute to increase the knowledge on the pathophysiology of neurodegenerative diseases. These models reproduce different aspects of a given disease, as well as the histopathological lesions and its main symptoms. The purpose of this review is to present the main animal models for AD, PD, and Huntington's disease.

    2014-01-01

    The pathophysiology of tinnitus is poorly understood and treatments are often unsuccessful. A number of animal models have been developed in order to gain a better understanding of tinnitus. A great deal has been learned from these models re-garding the electrophysiological and neuroanatomical correlates of tinnitus following exposure to noise or ototoxic drugs. Re-liable behavioral data is important for determining whether such electrophysiological or neuroanatomical changes are indeed related to tinnitus. Of the many documented tinnitus animal behavioral paradigms, the acoustic startle reflex had been pro-posed as a simple method to identify the presence or absence of tinnitus. Several behavioral models based on conditioned re-sponse suppression paradigms have also been developed. In addition to determining the presence or absence of tinnitus, some of the behavioral paradigms have provided signs of the onset, frequency, and intensity of tinnitus in animals. Although none of these behavioral models have been proved to be a perfect model, these studies provide useful information on understanding the neural mechanisms underlying tinnitus.

    Full Text Available Cardiovascular diseases are the first leading cause of death and morbidity in developed countries. The use of animal models have contributed to increase our knowledge, providing new approaches focused to improve the diagnostic and the treatment of these pathologies. Several models have been developed to address cardiovascular complications, including atherothrombotic and cardiac diseases, and the same pathology have been successfully recreated in different species, including small and big animal models of disease. However, genetic and environmental factors play a significant role in cardiovascular pathophysiology, making difficult to match a particular disease, with a single experimental model. Therefore, no exclusive method perfectly recreates the human complication, and depending on the model, additional considerations of cost, infrastructure, and the requirement for specialized personnel, should also have in mind. Considering all these facts, and depending on the budgets available, models should be selected that best reproduce the disease being investigated. Here we will describe models of atherothrombotic diseases, including expanding and occlusive animal models, as well as models of heart failure. Given the wide range of models available, today it is possible to devise the best strategy, which may help us to find more efficient and reliable solutions against human cardiovascular diseases.

    Domenico Santoro

    2014-12-01

    Full Text Available Allergic diseases have great impact on the quality of life of both people and domestic animals. They are increasing in prevalence in both animals and humans, possibly due to the changed lifestyle conditions and the decreased exposure to beneficial microorganisms. Dogs, in particular, suffer from environmental skin allergies and develop a clinical presentation which is very similar to the one of children with eczema. Thus, dogs are a very useful species to improve our understanding on the mechanisms involved in people’s allergies and a natural model to study eczema. Animal models are frequently used to elucidate mechanisms of disease and to control for confounding factors which are present in studies with patients with spontaneously occurring disease and to test new therapies that can be beneficial in both species. It has been found that drugs useful in one species can also have benefits in other species highlighting the importance of a comprehensive understanding of diseases across species and the value of comparative studies. The purpose of the current article is to review allergic diseases across species and to focus on how these diseases compare to the counterpart in people.

  13. Animal models of source memory.

    Crystal, Jonathon D

    2016-01-01

    Source memory is the aspect of episodic memory that encodes the origin (i.e., source) of information acquired in the past. Episodic memory (i.e., our memories for unique personal past events) typically involves source memory because those memories focus on the origin of previous events. Source memory is at work when, for example, someone tells a favorite joke to a person while avoiding retelling the joke to the friend who originally shared the joke. Importantly, source memory permits differentiation of one episodic memory from another because source memory includes features that were present when the different memories were formed. This article reviews recent efforts to develop an animal model of source memory using rats. Experiments are reviewed which suggest that source memory is dissociated from other forms of memory. The review highlights strengths and weaknesses of a number of animal models of episodic memory. Animal models of source memory may be used to probe the biological bases of memory. Moreover, these models can be combined with genetic models of Alzheimer's disease to evaluate pharmacotherapies that ultimately have the potential to improve memory.

  14. Skepticism, empathy, and animal suffering.

    Science.gov (United States)

    Aaltola, Elisa

    2013-12-01

    The suffering of nonhuman animals has become a noted factor in deciding public policy and legislative change. Yet, despite this growing concern, skepticism toward such suffering is still surprisingly common. This paper analyzes the merits of the skeptical approach, both in its moderate and extreme forms. In the first part it is claimed that the type of criterion for verification concerning the mental states of other animals posed by skepticism is overly (and, in the case of extreme skepticism, illogically) demanding. Resting on Wittgenstein and Husserl, it is argued that skepticism relies on a misguided epistemology and, thus, that key questions posed by it face the risk of absurdity. In the second part of the paper it is suggested that, instead of skepticism, empathy together with intersubjectivity be adopted. Edith Stein's take on empathy, along with contemporary findings, are explored, and the claim is made that it is only via these two methods of understanding that the suffering of nonhuman animals can be perceived.

  15. Associative concept learning in animals.

    Science.gov (United States)

    Zentall, Thomas R; Wasserman, Edward A; Urcuioli, Peter J

    2014-01-01

    Nonhuman animals show evidence for three types of concept learning: perceptual or similarity-based in which objects/stimuli are categorized based on physical similarity; relational in which one object/stimulus is categorized relative to another (e.g., same/different); and associative in which arbitrary stimuli become interchangeable with one another by virtue of a common association with another stimulus, outcome, or response. In this article, we focus on various methods for establishing associative concepts in nonhuman animals and evaluate data documenting the development of associative classes of stimuli. We also examine the nature of the common within-class representation of samples that have been associated with the same reinforced comparison response (i.e., many-to-one matching) by describing manipulations for distinguishing possible representations. Associative concepts provide one foundation for human language such that spoken and written words and the objects they represent become members of a class of interchangeable stimuli. The mechanisms of associative concept learning and the behavioral flexibility it allows, however, are also evident in the adaptive behaviors of animals lacking language.

Ce transport du texte vers un autre régime sémiotique fait penser à celui qui s’effectue dans le calligramme : En s’animant, le mot ne s’acharne pas seulement à rendre sensibles des choses mouvantes au niveau de son « contenu », mais il inscrit ce mouvement au niveau de son « contenant », de sa matière écrite. C’est, entre autres, à cause de ces nouvelles « contaminations » intersémiotiques entre texte et image que Xavier Malbreil a intitulé sa création numérique 10 poèmes en 4 dimensions. À travers une analyse détaillée des calligrammes animés dans l’œuvre de Xavier Malbreil, mon article propose une réflexion autour d’une éventuelle présence de la quatrième dimension dans l’espace-réseau.Ever since images and words can be animated and hypertextualized on electronic supports, authors have started dreaming about a new semantic proximity between words and images. On the visible surface of the screen, words have become animated like images, and have acquired a new graphic dimension. This transfer of text onto another semiotic mode is reminiscent of the way calligrammes work. In becoming animated, the word not only makes visible a dynamic semantic “content”, but it also inscribes this movement on the level of its “container”, the written matter. Because of these new intersemiotic “contaminations” between text and image, Xavier Malbreil entitled his eletronic creation 10 poems in four dimensions. Through a detailed analysis of the animated calligrammes in Xavier Malbreil’s work, my article offers a reflection about the possible presence of a fourth dimension on

  19. Narrating Animal Trauma in Bulgakov and Tolstoy

    Anastassiya Andrianova

    2016-11-01

    Full Text Available Following the recent “animal turn” in literary studies, which has inspired scholars to revisit traditional human-centered interpretations of texts narrated by animals, this article focuses on the convergence of animal studies and trauma theory. It offers new animal-centered close readings of Tolstoy’s Strider and Bulgakov’s Heart of a Dog, paying attention to animal pain rather than seeing it, and the text as a whole, as an allegory of human society. Like many other authors of literary fiction featuring animal narrators, Tolstoy and Bulgakov employ a kind of empathic ventriloquism to narrate animal pain, an important project which, however, given the status of both the animal and trauma outside human language, and thus susceptible to being distorted by it, produces inauthentic discourse (animal-like, rather than animal narration; therefore, these authors get closest to animal pain, not through sophisticated narration, but through the use of ellipses and onomatopoeia. Ultimately, any narratological difficulty with animal focalization is minor compared to the ethical imperative of anti-speciesist animal-standpoint criticism, and the goal is to reconceive the status of animals in literature so as to change their ontological place in the world, urging that this critical work and animal rights advocacy be continued in the classroom.

  20. Cytokinesis in plant and animal cells: endosomes 'shut the door'.

    Science.gov (United States)

    Baluska, Frantisek; Menzel, Diedrik; Barlow, Peter W

    2006-06-01

    For many years, cytokinesis in eukaryotic cells was considered to be a process that took a variety of forms. This is rather surprising in the face of an apparently conservative mitosis. Animal cytokinesis was described as a process based on an actomyosin-based contractile ring, assembling, and acting at the cell periphery. In contrast, cytokinesis of plant cells was viewed as the centrifugal generation of a new cell wall by fusion of Golgi apparatus-derived vesicles. However, recent advances in animal and plant cell biology have revealed that many features formerly considered as plant-specific are, in fact, valid also for cytokinetic animal cells. For example, vesicular trafficking has turned out to be important not only for plant but also for animal cytokinesis. Moreover, the terminal phase of animal cytokinesis based on midbody microtubule activity resembles plant cytokinesis in that interdigitating microtubules play a decisive role in the recruitment of cytokinetic vesicles and directing them towards the cytokinetic spaces which need to be plugged by fusing endosomes. Presently, we are approaching another turning point which brings cytokinesis in plant and animal cells even closer. As an unexpected twist, new studies reveal that both plant and animal cytokinesis is driven not so much by Golgi-derived vesicles but rather by homotypically and heterotypically fusing endosomes. These are generated from cytokinetic cortical sites defined by preprophase microtubules and contractile actomyosin ring, which induce local endocytosis of both the plasma membrane and cell wall material. Finally, plant and animal cytokinesis meet together at the physical separation of daughter cells despite obvious differences in their preparatory events.

    2009-11-01

    The assessment of animal welfare relates to investigations of how animals try to cope with their environment, and how easy or how difficult it is for them to do so. The use of rigorous scientific methods to assess this has grown over the past few decades, and so our understanding of the needs of animals has improved during this time. Much of the work in the field of animal welfare has been conducted on farm animals, but it is important to consider how the methods and approaches used in assessing farm animal welfare have been, and can be, adapted and applied to the measurement of welfare in animals in other domains, such as in zoos. This is beneficial to our understanding of both the theoretical knowledge, and the practicability of methods. In this article, some of the commonly-used methods for measuring animal welfare will be discussed, as well as some practical considerations in assessing the welfare of zoo animals.

    Full Text Available Animal experiments are of paramount importance in the pre-clinical screening of new chemical entity. On the other hand, various regulatory guidelines for animal experiments are becoming more stringent in the face of worldwide protests by animal rights activists. Moreover, simulated animal experiments’ softwares are being developed and they can be implemented in the postgraduate and graduate students’ curriculum for demonstration of standard physiological and pharmacological principles compared to real time animal experiments. In fact, implementation of virtual experiment will decrease hand on experience of animal experiments among medical students, but after medical graduation, animal experiment is lest utilized during their day to day clinical practice. Similarly, in case of postgraduate pharmacology curriculum, computer based virtual animal experiments can facilitate teaching and learning in a short span of time with various protocols, without sacrificing any animal for already established experimental outcomes.

So animals are important in daily life, they are also used in many works to express the Author’s thoughts.This thesis aims to investigate the overall relationship between ecology and Gary Snyder’s poetry and poetics. The American poet Gary Snyder, known as one of the Beat Generation, draws attention to the healing and recuperation while the others overthrow and reject everything. Snyder is also regarded as the Poet Laureate of deep ecology for his great contribution to deep ecology movement.Pride and prejudice took the Britain of the end of the 18 th century as the background. In this paper, three marriage cases of young men and young ladies and a representative madam are taken as the typical examples to research and discuss.The novel "Vanity fair" is the masterpiece of William Makepeace Thackeray, in which the author illustrates that the life of upper-class aristocratic capitalists in the 19 th century. The lives of people are related to money and reputation. They are likely to try whichever means to fulfill their longings even most of them are bad ones. Through a series of comprehensive research and analysis, this novel is aimed to reveal those bad natures of the people under the background of the development of capitalism.This essay is about mythological criticism reflected in Eugene O’Neill’s play-The Hairy Ape. The Hairy Ape documents the downward spiral of a fireman who works on a ship during the period of industrial prosperity in capitalist society. In fact, his degeneration is the miniature of the whole people of that age. Mythological criticism, especially the Jungian psychology and his archetypal insights, will help to understand how the theme is conveyed.

    Animal experimentation is carried out in consultation with the veterinary wing but it is essential that be familiar with experimental protocols of animal model to be able to design an approriate study. This is more so in place where the veterinary facilities are not easily available.Span Rabbits are commonly used as subjects for screening implant material. They have gained favour for their numerous advantages even though they should be ideally used prior to testing in a larger animal model. Though experimentation on rabbits seems to be easy there are many pitfalls. Our endeavor in this article is to integrate all the data about maintaining rabbits as a model and to critically analyze it on the basis of our experimentation.

    Full Text Available Abstract Background The concept of conserved processes presents unique opportunities for using nonhuman animal models in biomedical research. However, the concept must be examined in the context that humans and nonhuman animals are evolved, complex, adaptive systems. Given that nonhuman animals are examples of living systems that are differently complex from humans, what does the existence of a conserved gene or process imply for inter-species extrapolation? Methods We surveyed the literature including philosophy of science, biological complexity, conserved processes, evolutionary biology, comparative medicine, anti-neoplastic agents, inhalational anesthetics, and drug development journals in order to determine the value of nonhuman animal models when studying conserved processes. Results Evolution through natural selection has employed components and processes both to produce the same outcomes among species but also to generate different functions and traits. Many genes and processes are conserved, but new combinations of these processes or different regulation of the genes involved in these processes have resulted in unique organisms. Further, there is a hierarchy of organization in complex living systems. At some levels, the components are simple systems that can be analyzed by mathematics or the physical sciences, while at other levels the system cannot be fully analyzed by reducing it to a physical system. The study of complex living systems must alternate between focusing on the parts and examining the intact whole organism while taking into account the connections between the two. Systems biology aims for this holism. We examined the actions of inhalational anesthetic agents and anti-neoplastic agents in order to address what the characteristics of complex living systems imply for inter-species extrapolation of traits and responses related to conserved processes. Conclusion We conclude that even the presence of conserved processes is

    Hypertension is classified as idiopathic or secondary. In animals with idiopathic hypertension, persistently elevated blood pressure is not caused by an identifiable underlying or predisposing disease. Until recently, more than 95% of cases of hypertension in humans were diagnosed as idiopathic. New studies have shown, however, a much higher prevalence of secondary causes, such as primary hyperaldosteronism. In dogs and cats, secondary hypertension is the most prevalent form and is subclassified into renal and endocrine hypertension. This review focuses on the most common causes of endocrine hypertension in dogs and cats.

    From 1791, patients in our country were treated according to the theory of animal magnetism or mesmerism, elaborated by the physician Mesmer (1734-1815). An invisible substance was supposed to be the medium linking cosmic phenomena with life on earth. By distributing this substance harmoniously over a patient's body, a magnetizer could cure that patient. Subsequently, it was also believed that the treatment induced somnambulism (or hypnosis) and gave the patient 'inner vision': insight into his own ailment and consequently, into the desired treatment. Owing to lack of good long-term results, magnetism after a few years was dropped from the regular circuit.

    The development of animal models of drug reward and addiction is an essential factor for progress in understanding the biological basis of this disorder and for the identification of new therapeutic targets. Depending on the component of reward to be studied, one type of animal model or another may be used. There are models of reinforcement based on the primary hedonic effect produced by the consumption of the addictive substance, such as the self-administration (SA) and intracranial self-stimulation (ICSS) paradigms, and there are models based on the component of reward related to associative learning and cognitive ability to make predictions about obtaining reward in the future, such as the conditioned place preference (CPP) paradigm. In recent years these models have incorporated methodological modifications to study extinction, reinstatement and reconsolidation processes, or to model specific aspects of addictive behavior such as motivation to consume drugs, compulsive consumption or drug seeking under punishment situations. There are also models that link different reinforcement components or model voluntary motivation to consume (two-bottle choice, or drinking in the dark tests). In short, innovations in these models allow progress in scientific knowledge regarding the different aspects that lead individuals to consume a drug and develop compulsive consumption, providing a target for future treatments of addiction.

    This paper explores a new approach to validating software implementations that have been produced from formally-verified algorithms. Although visual inspection gives some confidence that the implementations faithfully reflect the formal models, it does not provide complete assurance that the software is correct. The proposed approach, which is based on animation of formal specifications, compares the outputs computed by the software implementations on a given suite of input values to the outputs computed by the formal models on the same inputs, and determines if they are equal up to a given tolerance. The approach is illustrated on a prototype air traffic management system that computes simple kinematic trajectories for aircraft. Proofs for the mathematical models of the system's algorithms are carried out in the Prototype Verification System (PVS). The animation tool PVSio is used to evaluate the formal models on a set of randomly generated test cases. Output values computed by PVSio are compared against output values computed by the actual software. This comparison improves the assurance that the translation from formal models to code is faithful and that, for example, floating point errors do not greatly affect correctness and safety properties.

    ARGOS satellite tracking technology has enabled a tremendous increase in our understanding of the movement patterns of a diverse array of marine vertebrates from Sharks to marine mammals. Our current understanding has moved from simple descriptions of large scale migratory patterns to much more sophisticated comparisons of animal movements and behavior relative to oceanic features. Further, animals are increasingly used to carry sensors that can acquire water column temperature and salinity profiles. However, a major limitation of this work is the spatial precision of ARGOS locations. ARGOS provides 7 location qualities that range from 3,2,1,0,A,B,Z and correspond to locations with a precision of 150m to tens of kilometers. Until recently, GPS technology could not be effectively used with marine mammals because they did not spend sufficient time at the surface to allow complete acquisition of satellite information. The recent development of Fastloc technology has allowed the development of GPS tags that can be deployed on marine mammals. Here we compare the location quality and frequency derived from standard ARGOS PTTs to Fastloc GPS locations acquired from 11 northern elephant seals, 5 California and 5 Galapagos sea lions and 1 Cape and 3 Australian fur seals. Our results indicate that GPS technology will greatly enhance our ability to understand the movement patterns of marine vertebrates and the in-situ oceanographic data they collect.

  9. Lysozymes in the animal kingdom

    Indian Academy of Sciences (India)

    Lien Callewaert; Chris W Michiels

    2010-03-01

    Lysozymes (EC 3.2.1.17) are hydrolytic enzymes, characterized by their ability to cleave the -(1,4)-glycosidic bond between -acetylmuramic acid and -acetylglucosamine in peptidoglycan, the major bacterial cell wall polymer. In the animal kingdom, three major distinct lysozyme types have been identified – the c-type (chicken or conventional type), the g-type (goose-type) and the i-type (invertebrate type) lysozyme. Examination of the phylogenetic distribution of these lysozymes reveals that c-type lysozymes are predominantly present in the phylum of the Chordata and in different classes of the Arthropoda. Moreover, g-type lysozymes (or at least their corresponding genes) are found in members of the Chordata, as well as in some bivalve mollusks belonging to the invertebrates. In general, the latter animals are known to produce i-type lysozymes. Although the homology in primary structure for representatives of these three lysozyme types is limited, their three-dimensional structures show striking similarities. Nevertheless, some variation exists in their catalytic mechanisms and the genomic organization of their genes. Regarding their biological role, the widely recognized function of lysozymes is their contribution to antibacterial defence but, additionally, some lysozymes (belonging to different types) are known to function as digestive enzymes.

  11. A revised taxonomy of assistance animals

    Directory of Open Access Journals (Sweden)

    Lindsay Parenti, MA, BCBA

    2013-08-01

    Full Text Available The use of animals in various assistive, therapeutic, and emotional support roles has contributed to the uncoordinated expansion of labels used to distinguish these animals. To address the inconsistent vocabulary and confusion, this article proposes a concise taxonomy for classifying assistance animals. Several factors were identified to differentiate categories, including (1 whether the animal performs work or tasks related to an individual’s disability; (2 the typical level of skill required by the animal performing the work or task; (3 whether the animal is used by public service, military, or healthcare professionals; (4 whether training certifications or standards are available; and (5 the existence of legal public access protections for the animal and handler. Acknowledging that some category labels have already been widely accepted or codified, six functional categories were identified: (1 service animal; (2 public service animal; (3 therapy animal; (4 visitation ­animal; (5 sporting, recreational, or agricultural animal; and (6 support animal. This taxonomy provides a clear vocabulary for use by consumers, professionals working in the field, researchers, policy makers, and regulatory agencies.

    Amiot, Catherine E; Bastian, Brock

    2017-01-01

    Interactions with animals are pervasive in human life, a fact that is reflected in the burgeoning field of human-animal relations research. The goal of the current research was to examine the psychology of our social connection with other animals, by specifically developing a measure of solidarity with animals. In 8 studies using correlational, experimental, and longitudinal designs, solidarity with animals predicted more positive attitudes and behaviors toward animals, over and above existing scales of identification, and even when this implied a loss of resources and privileges for humans relative to animals. Solidarity with animals also displayed predicted relationships with relevant variables (anthropomorphism, empathy). Pet owners and vegetarians displayed higher levels of solidarity with animals. Correlational and experimental evidence confirmed that human-animal similarity heightens solidarity with animals. Our findings provide a useful measure that can facilitate important insights into the nature of our relationships with animals.

  14. Nanotechnology and its applications in Veterinary and Animal Science

    Directory of Open Access Journals (Sweden)

    S. S. Patil

    Full Text Available Nanotechnology has a tremendous potential to revolutionize agriculture and livestock sector. It can provide new tools for molecular and cellular biology, biotechnology, veterinary physiology, animal genetics, reproduction etc. which will allow researchers to handle biological materials such as DNA, proteins or cells in minute quantities usually nano-liters or pico-liters. Nanotechnology tools like microfluidics, nanomaterials, bioanalytical nanosensors, etc. has the potential to solve many more puzzles related to animal health, production, reproduction and prevention and treatment of diseases. It is reasonable to presume that in the upcoming year’s nanotechnology research will reform the science and technology of the animal health and will help to boost up the livestock production. Nanotechnology will have a profound impact, but not in the immediate future as it is in the early stages of its development and needs to equip scientists, engineers and biologists to work at the cellular and molecular levels for significant benefits in healthcare and animal medicine. But It is reasonable to presume that in the upcoming year’s nanotechnology research will revolutionize animal health and help to boost up livestock production. [Vet World 2009; 2(12.000: 475-477

  17. Suicide among animals: a review of evidence.

    Science.gov (United States)

    Preti, Antonio

    2007-12-01

    Naturalists have not identified suicide in nonhuman species in field situations, despite intensive study of thousands of animal species. In this review, evidence on suicidal behavior among animals is analyzed to discover analogies with human suicidal behavior. Literature was retrieved by exploring Medline/PubMed and PsychINFO databases (1967-2007) and through manual literature searches. Keyword terms were "suicide or suicidal behavior" and "animal or animal behavior." Few empirical investigations have been carried out on this topic. Nevertheless, sparse evidence supports some resemblance between the self-endangering behavior observed in the animal kingdom, particularly in animals held in captivity or put under pressure by environmental challenges, and suicidal behavior among humans. Animal models have contributed to the study of both normal and pathological human behaviors: discovering some correlates of suicide among animals could be a valid contribution to the field.

  18. Global perspectives on animal welfare: Europe.

    Science.gov (United States)

    Caporale, V; Alessandrini, B; Dalla Villa, P; Del Papa, S

    2005-08-01

    Effective implementation and enforcement of legislation is essential to ensure animal welfare. In the World Organisation for Animal Health (OIE) European Region the well-established body of national and European Union laws in existence is growing continuously. The growth is due to various factors, such as new technology in animal farming and experimentation, exploitation of wildlife, new understanding of animal needs, and increasing public awareness and concern. The latter, in particular, determines the need for new animal welfare legislation to regulate and discipline the 'use' of animals for different purposes, such as food production, companionship, work and leisure. This paper intends to provide an overview of the more relevant activities carried out by the Council of Europe and the European Union in the field of animal welfare. The authors identify eLearning as a tool to harmonise the interpretation and the implementation of animal welfare legislation.

    Science.gov (United States)

    Rabinowitz, Peter; Gordon, Zimra; Chudnov, Daniel; Wilcox, Matthew; Odofin, Lynda; Liu, Ann; Dein, Joshua

    2006-04-01

    We conducted a systematic review of the scientific literature from 1966 to 2005 to determine whether animals could provide early warning of a bioterrorism attack, serve as markers for ongoing exposure risk, and amplify or propagate a bioterrorism outbreak. We found evidence that, for certain bioterrorism agents, pets, wildlife, or livestock could provide early warning and that for other agents, humans would likely manifest symptoms before illness could be detected in animals. After an acute attack, active surveillance of wild or domestic animal populations could help identify many ongoing exposure risks. If certain bioterrorism agents found their way into animal populations, they could spread widely through animal-to-animal transmission and prove difficult to control. The public health infrastructure must look beyond passive surveillance of acute animal disease events to build capacity for active surveillance and intervention efforts to detect and control ongoing outbreaks of disease in domestic and wild animal populations.

  20. Establishment for quality control of experimental animal

    Energy Technology Data Exchange (ETDEWEB)

    Kim, Tae Hwan; Kim, Soo Kwan; Kim, Tae Kyoung

    1999-06-01

    Until now, because we have imported experimental animal from foreign experimental animal corporation, we could have saved money by establishing the quality control of animal in barrier system. In order to improve the quality of animal experiment and efficiency of biomedical study, it is indispensable to control many factors that effect in the experiment. Therefore, it is essential to organize the system of laboratory animal care for enhancing reliability and revivability of experimental results. The purpose of the present investigation was to establish the quality control system of experimental animals that we can provide good quality animals according to the experimental condition of each investigator although the exact quality control system to estimate the infection of bacteria and virus easily remains ill-defined yet. Accordingly, we established the useful quality control system for microbiologic monitoring and environmental monitoring to protect experimental animal from harmful bacteria and virus.

    2012-01-01

    Full Text Available The proliferation of studies bearing on the intellectual movement known as the "new materialisms" evinces that a material turn is becoming an important paradigm in environmental humanities. Ranging from social and science studies, feminism, to anthropology, geography, environmental philosophies and animal studies, this approach is bringing innovative ways of considering matter and material relations that, coupled with reflections on agency, text, and narrativity, are going to impact ecocriticism in an unprecedented way.In consideration of the relevance of this debate, we would like to draw for Ecozon@'s readers an introductory map of the new paradigm and introduce what can be called "material ecocriticism." We will illustrate what we consider to be its main features, situating them in the conceptual horizons of the new materialisms. From this genealogical sketch, we will examine the re-definitions of concepts like matter, agency, discursivity, and intentionality, with regard to their effects on ecocriticism and in terms of their ethical perspectives.

    Gawronska-Kozak, Barbara; Grabowska, Anna; Kopcewicz, Marta; Kur, Anna

    2014-03-01

    Cutaneous injury in the majority of vertebrate animals results in the formation of a scar in the post-injured area. Scar tissues, although beneficial for maintaining integrity of the post-wounded region often interferes with full recovery of injured tissues. The goal of wound-healing studies is to identify mechanisms to redirect reparative pathways from debilitating scar formation to regenerative pathways that lead to normal functionality. To perform such studies models of regeneration, which are rare in mammals, are required. In this review we discussed skin regenerative capabilities present in lower vertebrates and in models of skin scar-free healing in mammals, e.g. mammalian fetuses. However, we especially focused on the attributes of two unusual models of skin scar-free healing capabilities that occur in adult mammals, that is, those associated with nude, FOXN1-deficient mice and in wild-type African spiny mice.

    1977-10-01

    The sympathetic nervous innervation of the head was surgically transected in the horse, cow, sheep and goat. The site of transection was preganglionic in all 4 species and ganglionic-postganglionic in 2 additional horses. The Horner's syndrome, manifested as a result of the iatrogenic lesion, varied with the species. Ptosis was the most constant sign in all species. Unilateral sweating over the face and proximal neck, particularly at the base of the ear, was the most prominent feature in the horse. The cow revealed distension of vasculature and cutaneous heat of the pinna, and a reduced production of beads of sweat over the nostril on the affected side. The goat and sheep exhibited little more than slight ptosis of the upper eyelid of the affected side as the most prominent sign. The ophthalmologic manifestations of Horner's syndrome seen in these large animals were not readily apparent and could easily be overlooked upon clinical examination.

  10. Animal welfare: neuro-cognitive approaches

    2010-01-01

    Full Text Available Many people maintain a naive belief that non-human animals consciously experience pain and suffering in similar ways to humans. Others tend to assume a more sceptical or agnostic attitude. Drawing on recent advances in research on animal cognition and neuroscience, the science of animal welfare is now beginning to address these issues empirically. We describe recent advances that may contribute to the main questions of animal welfare, namely whether animals are conscious and how we can assess good and bad welfare in animals. Evidence from psychology is described which demonstrate that many complex actions in humans can be carried out quite unconsciously and that human patients with certain sorts of brain damage can behave and manipulate objects properly while at the same time o consciously denying experience of them. The relevance of these findings with respect to the issue of animal consciousness is discussed. Evidence from animal cognition is described concerning the possibility that animals monitor the state of their own memories, show episodic-like knowledge and exhibit self-medication. Evidence from neuroscience concerning brain lateralization in non-human animals and its relevance to animal welfare is described. It is argued that in animals raised for economic purposes (milk and meat production differences in cognitive abilities and brain lateralization can affect adaptive behavioural, physiological and immune responses to environmental stressors.

    The development and design of animal facilities are described in terms of the technological needs for NASA's Biological Flight Research Laboratory. Animal habitats are presented with illustrations which encompass waste-collection techniques for microgravity conditions that reduce the need for crew participation. The technology is intended to be highly compatible with animal morphology, and airflow is employed as the primary mechanism of waste control. The airflow can be utilized in the form of localized high-speed directed flow that simultaneously provides a clean animal habitat and low airflow rates. The design of an animal-habitat testbed is presented which capitalizes on contamination-control mechanisms and suitable materials for microgravity conditions. The developments in materials and technologies represent significant contributions for the design of the centrifuge facilities for the Space Station Freedom.
