  7. Laboratory Animal Allergy in the Modern Era.

    Science.gov (United States)

    Jones, Meinir

    2015-12-01

    Laboratory animal workers face a high risk of developing laboratory animal allergy as a consequence of inhaling animal proteins at work; this has serious consequences for their health and future employment. Exposure to animal allergen remains to be the greatest risk factor although the relationship is complex, with attenuation at high allergen exposure. Recent evidence suggests that this may be due to a form of natural immunotolerance. Furthermore, the pattern of exposure to allergen may also be important in determining whether an allergic or a tolerant immune response is initiated. Risk associated with specific tasks in the laboratory need to be determined to provide evidence to devise a code of best practice for working within modern laboratory animal facilities. Recent evidence suggests that members of lipocalin allergens, such as Mus m 1, may act as immunomodulatory proteins, triggering innate immune receptors through toll-like receptors and promoting airway laboratory animal allergy. This highlights the need to understand the relationship between endotoxin, animal allergen and development of laboratory animal allergy to provide a safe working environment for all laboratory animal workers.

  11. [Spirograph for small laboratory animals].

    Science.gov (United States)

    Daniiarov, S B; Lanskiĭ, Iu M; Bebinov, E M

    1986-10-01

    A design of dry spirograph is described. It is characterized by greater precision, lack of inertia, high reliability, absence of respiration resistance, adequate form of recording, rapid resetting to any respiratory rate. The device consists of two similar injection syringes, photoelectric sensor for the identification of the initial moments of respiration stages, electromagnetic valves, two photoelectric converters of the air volume into the impulse signal, vacuum micro-pump, microcompressor and a system of air-driving tubes. In the initial position of pistons and valves the microcompressor pumps air into the inhalation cylinder and lifts the piston to the upper extreme position. With the signal marking the beginning of inspiration, the valves switch over and the piston lowers, pushing out the air, which moves into the animals' respiratory organs. Simultaneously, the signals of the inhaled air volume from the photoelectric transducer reach the recorder. During expiration the air pushes the piston down into the second cylinder and photoelectric transducer gives the information on the volume of the expired air.

  12. Laboratory Animal Models for Brucellosis Research

    Directory of Open Access Journals (Sweden)

    Teane M. A. Silva

    2011-01-01

    Full Text Available Brucellosis is a chronic infectious disease caused by Brucella spp., a Gram-negative facultative intracellular pathogen that affects humans and animals, leading to significant impact on public health and animal industry. Human brucellosis is considered the most prevalent bacterial zoonosis in the world and is characterized by fever, weight loss, depression, hepato/splenomegaly, osteoarticular, and genital infections. Relevant aspects of Brucella pathogenesis have been intensively investigated in culture cells and animal models. The mouse is the animal model more commonly used to study chronic infection caused by Brucella. This model is most frequently used to investigate specific pathogenic factors of Brucella spp., to characterize the host immune response, and to evaluate therapeutics and vaccines. Other animal species have been used as models for brucellosis including rats, guinea pigs, and monkeys. This paper discusses the murine and other laboratory animal models for human and animal brucellosis.

  13. Laboratory animal: biological reagent or living being?

    Directory of Open Access Journals (Sweden)

    C.V.P. Cardoso

    2014-01-01

    Full Text Available The duties of humans toward non-human animals and their rights in society have been debated for a long time. However, a discussion on the terminology used for the identification of laboratory animals is usually not considered, although the employment of inadequate terminology may generate disastrous consequences for the animals before, during, and after the experiment. This study intends to defend the use of appropriate terminology, call attention to an unethical attitude of certain professionals when dealing with experimental animals, and also propose operational mechanisms, which allow for those distortions to be corrected.

    2002-01-01

    This article concerns animal experimentation and official Mexican norm Nom 0062-Zoo-1999 entitled Technical specifications for the production, care and use of laboratory animals. The history of animal experimentation is briefly resumed. During the nineteenth century, doubts arose as to the right to expose animals to experimental procedures that frequently cause pain and suffering. The first law which protected animals against cruelty was passed in Great Britain in 1876; subsequently, other nations approved similar legislation. During the second part of the twentieth century, opposition to animal experimentation grew. Other groups, mainly scientists and pharmaceutical concerns, defended the right to use animals in research. New knowledge concerning the neurophysiology, cognitive capacity, and the animal faculty to experience pain is briefly mentioned. Guidelines on care and use of animals used in research published in several countries are listed. Finally, the recently published Mexican legislation (Norm) referring to production, care and use of laboratory animals is discussed and its benefits are stressed. PMID:12096401

    The slow scientific development in Latin America in recent decades has delayed the incorporation of laboratory animal experimentation; however, this situation has started to change. Today, extraordinary scientific progress is evident, which has promoted the introduction and increased use of laboratory animals as an important tool for the advancement of biomedical sciences. In the aftermath of this boom, the need to provide the scientific community with training and guidance in all aspects related to animal experimentation has arisen. It is the responsibility of each country to regulate this practice, for both bioethical and legal reasons, to ensure consideration of the animals' rights and welfare. The following manuscript is the result of papers presented at the International Workshop on Laboratory Animal Testing held at the Technical University of Ambato, Ecuador; it contains information regarding the current state of affairs in laboratory animal testing and emphasizes critical aspects such as main species used, ethical and legal principles, and experimental and alternative designs for animal use. These works aim to ensure good practices that should define scientific work. This document will be relevant to both researchers who aim to newly incorporate animal testing into their research and those who seek to update their knowledge. PMID:27656930

    Animal scientists have an extraordinary burden to promote the health and well-being of all animals in their care. Promoting species- or breed-appropriate behaviors through proper training and enrichment, regardless of animal housing, should be a paramount concern for all animal scientists working with exotic animals, laboratory animals, shelter animals, or privately owned pet animals. Developing ideal training and enrichment programs for any species begins with understanding basic behavior patterns and emotional systems of animals. The basic emotional systems in mammals have been extensively mapped; however, most of these studies are in the neuroscience literature and seldom read by animal science professionals. The emotional circuits for fear have been well documented through studies demonstrating that lesions to the amygdala will block both conditioned and unconditioned fear behaviors. Additionally, other core emotional systems including seeking (i.e., approaching a novel stimulus), rage, panic (e.g., separation stress), play, lust (i.e., sex drive), and care (e.g., mother-young nurturing behavior) have been identified. More recent neuroscience research has discovered the subcortical brain regions that drive different types of seeking behaviors. Research to increase the understanding of the emotional systems that drive both abnormal and normal animal behaviors could greatly improve animal welfare by making it possible to provide more effective environmental enrichment programs. Enrichment devices and methods could be specifically designed to enable the expression of highly motivated behaviors that are driven by emotional circuits in the brain. The objective of this paper is to increase awareness of animal scientists to the field of neuroscience studying animal emotions and the application of that science to improve the welfare of captive exotic animals, laboratory animals, and pets with environmental enrichment.

  7. Laboratory training manual on radioimmunoassay in animal reproduction

    International Nuclear Information System (INIS)

    Reproduction must always be regarded as one of the major limiting factors in animal production and many of the modern methods for improving reproduction rely heavily on the ability to measure hormone levels in blood and milk. This has produced a world-wide demand for laboratory facilities to carry out hormone assays and the need for specialist training to allow these assays to be undertaken. The need to measure nanogram and picogram quantities and the use of radionuclides require a good deal of skill and care and this Manual has been prepared to aid training and provide the sort of information that rarely appears in scientific papers. It represents a further step in the Joint FAO/IAEA Division's series of Laboratory Training Manuals, and has been designed to aid training programmes of the type carried out during the Joint FAO/IAEA Interregional Training Course on Radioimmunoassay and its Application in Research on Animal Reproduction at Cornell University in July 1982. Many of the laboratory exercises described in this Manual are based on those conducted during the course

    Emerging infectious diseases arising from livestock and wildlife pose serious threats to global human health, as shown by a series of continuous outbreaks involving highly pathogenic influenza, SARS, Ebola and MERS. The risk of pandemics and bioterrorism threats is ever present and growing, but our ability to combat them is limited by the lack of available vaccines, therapeutics and rapid diagnostics. The use of high bio-containment facilities, such as the CSIRO Australian Animal Health Laboratory, plays a key role studying these dangerous pathogens and facilitates the development of countermeasures. To combat diseases like MERS, we must take a holistic approach that involves the development of early biomarkers of infection, a suite of treatment options (vaccines, anti-viral drugs and antibody therapeutics) and appropriate animal models to test the safety and efficacy of candidate treatments.

    1992-10-01

    The dsinezumi shrew (Crocidura dsinezumi), a small insectivore, has been bred for the first time as a laboratory animal. The original animals were captured using Sherman's live traps and transferred into wooden cages. After several generations they were housed in plastic cages. Their diet consisted of trout pellets, cat food, and water provided ad libitum. Monogamous pairs were housed together for 2-3 weeks for mating, and the male was separated from the female during delivery and nursing. In captivity, the reproductive activity was observed throughout the year and the gestation period was estimated at 28-30 days with a litter size of between 1 and 4 pups. Pups grew very rapidly, and reached adult body size (mean: male, 9.7 g; female, 8.3 g) and sexual maturation at 6-8 weeks of age. The reproductive life was estimated at one and a half years, while the longevity was approximately 2 years. PMID:1451754

    In this issue are assembled 10 fascinating, well-researched papers that describe the emerging field centered on the microbiome of vertebrate animals and how these complex microbial populations play a fundamental role in shaping homeostasis of the host. The content of the papers will deal with bacteria and, because of relative paucity of information on these organisms, will not include discussions on viruses, fungus, protozoa, and parasites that colonize various animals. Dissecting the number and interactions of the 500-1000 bacterial species that can inhabit the intestines of animals is made possible by advanced DNA sequencing methods, which do not depend on whether the organism can be cultured or not. Laboratory animals, particularly rodents, have proven to be an indispensable component in not only understanding how the microbiome aids in digestion and protects the host against pathogens, but also in understanding the relationship of various species of bacteria to development of the immune system. Importantly, this research elucidates purported mechanisms for how the microbiome can profoundly affect initiation and progression of diseases such as type 1 diabetes, metabolic syndromes, obesity, autoimmune arthritis, inflammatory bowel disease, and irritable bowel syndrome. The strengths and limitations of the use of germfree mice colonized with single species of bacteria, a restricted flora, or most recently the use of human-derived microbiota are also discussed.

S. pneumoniae was isolated from nose, lung and respiratory tract, eye, ear and other sites. METHODOLOGY/PRINCIPAL FINDINGS: Carriage of the same isolate of S. pneumoniae over a period of up to 22 weeks was shown for four mastomys. Forty-one animals showed disease symptoms. Pneumococcal isolates were characterized by optochin sensitivity, bile solubility, DNA hybridization, pneumolysin PCR, serotyping and multilocus sequence typing. Eighteen of the 32 mastomys isolates (56% were optochin resistant, all other isolates were optochin susceptible. All mastomys isolates were serotype 14, all guinea pig isolates serotype 19F, all horse isolates serotype 3. Rats had serotypes 14 or 19A, mice 33A or 33F. Dolphins had serotype 23F, the gorilla serotype 14. Cats and dogs had many different serotypes. Four isolates were resistant to macrolides, three isolates also to clindamycin and tetracycline. Mastomys isolates were sequence type (ST 15 (serotype 14, an ST/serotype combination commonly found in human isolates. Cats, dogs, pet rats, gorilla and dolphins showed various human ST/serotype combinations. Lab rats and lab mice showed single locus variants (SLV of human STs, in human ST/serotype combinations. All guinea pig isolates showed the same completely new combination of known alleles. The horse isolates showed an unknown allele combination and three new alleles. CONCLUSIONS/SIGNIFICANCE: The isolates found in mastomys, mice, rats, cats, dogs, gorilla and dolphins are most likely identical to human pneumococcal isolates. Isolates from

  15. Pain and Laboratory Animals: Publication Practices for Better Data Reproducibility and Better Animal Welfare.

    Science.gov (United States)

    Carbone, Larry; Austin, Jamie

    2016-01-01

    Scientists who perform major survival surgery on laboratory animals face a dual welfare and methodological challenge: how to choose surgical anesthetics and post-operative analgesics that will best control animal suffering, knowing that both pain and the drugs that manage pain can all affect research outcomes. Scientists who publish full descriptions of animal procedures allow critical and systematic reviews of data, demonstrate their adherence to animal welfare norms, and guide other scientists on how to conduct their own studies in the field. We investigated what information on animal pain management a reasonably diligent scientist might find in planning for a successful experiment. To explore how scientists in a range of fields describe their management of this ethical and methodological concern, we scored 400 scientific articles that included major animal survival surgeries as part of their experimental methods, for the completeness of information on anesthesia and analgesia. The 400 articles (250 accepted for publication pre-2011, and 150 in 2014-15, along with 174 articles they reference) included thoracotomies, craniotomies, gonadectomies, organ transplants, peripheral nerve injuries, spinal laminectomies and orthopedic procedures in dogs, primates, swine, mice, rats and other rodents. We scored articles for Publication Completeness (PC), which was any mention of use of anesthetics or analgesics; Analgesia Use (AU) which was any use of post-surgical analgesics, and Analgesia Completeness (a composite score comprising intra-operative analgesia, extended post-surgical analgesia, and use of multimodal analgesia). 338 of 400 articles were PC. 98 of these 338 were AU, with some mention of analgesia, while 240 of 338 mentioned anesthesia only but not post-surgical analgesia. Journals' caliber, as measured by their 2013 Impact Factor, had no effect on PC or AU. We found no effect of whether a journal instructs authors to consult the ARRIVE publishing guidelines

    2011-01-01

    Investigating how different pharmacological compounds may enhance learning, memory, and higher-order cognitive functions in laboratory animals is the first critical step toward the development of cognitive enhancers that may be used to ameliorate impairments in these functions in patients suffering from neuropsychiatric disorders. Rather than focus on one aspect of cognition, or class of drug, in this review we provide a broad overview of how distinct classes of pharmacological compounds may enhance different types of memory and executive functioning, particularly those mediated by the prefrontal cortex. These include recognition memory, attention, working memory, and different components of behavioral flexibility. A key emphasis is placed on comparing and contrasting the effects of certain drugs on different cognitive and mnemonic functions, highlighting methodological issues associated with this type of research, tasks used to investigate these functions, and avenues for future research. Viewed collectively, studies of the neuropharmacological basis of cognition in rodents and non-human primates have identified targets that will hopefully open new avenues for the treatment of cognitive disabilities in persons affected by mental disorders.

Although there are many different classifications for microbiological standardization of laboratory animals, they can be basically classified as; gnotobiotic animals, animals bred with a complete barrier system (Germ free, GF, with Colonization-Resistant Flora; CRF, animals bred with a partial barrier system (Specified Pathogen Free, SPF, and animals bred by conventional methods in units without barriers (Conventional; CV. Monitoring of microbiological standardization is carried out in two ways. One is controlling barrier systems (process control and the other is controlling laboratory animals (product control. In controlling barrier systems samples are taken routinely from ambient air, surfaces, base plate materials of animals, foods and waters, and microbiological tests are carried out. FELASA guidelines are frequently used in monitoring laboratory animals. These guidelines where the monitoring frequency, sample size, micro-organisms to be tested, vary according to the microbiological quality of the animals, and test methods and are frequently updated by FELASA and shared in their web pages. In our country, in general, laboratory animals used for experimental studies present no microbiological standardization, and follow-up protocols are not implemented. Therefore, construction of facilities for the production of microbiologically standard animals and establishment of backup laboratories testing microbiological quality should be established.

    There is a current need for a change in the attitudes of researchers toward the care and use of experimental animals in India. This could be achieved through improvements in the provision of training, to further the integration of the Three Rs concept into scientific research and into the regulations of the Committee for the Purpose of Control and Supervision of Experiments on Animals (CPCSEA). A survey was performed after participants undertook the Federation of European Laboratory Animal Science Associations (FELASA) Category C-based course on Laboratory Animal Science (in 2013 and 2015). It revealed that the participants subsequently employed, in their future research, the practical and theoretical Three Rs approaches that they had learned. This is of great importance in terms of animal welfare, and also serves to benefit their research outcomes extensively. All the lectures, hands-on practical sessions and supplementary elements of the courses, which also involved the handling of small animals and procedures with live animals, were well appreciated by the participants. Insight into developments in practical handling and welfare procedures, norms, directives, and ethical use of laboratory animals in research, was also provided, through the comparison of results from the 2013 and 2015 post-course surveys.

  13. Practical experiences with irradiation of laboratory animals' feed

    International Nuclear Information System (INIS)

    The increasing need for well-defined, standardized experimental animals for research has led to the development of many new methods of keeping the animals free from pathogenic microorganisms. In this connection the problem of contaminated food has taken on ever greater significance. The methods most commonly used today, namely chemical treatment and heat treatment of the fodder, have many disadvantages and interest in the use of radiation sterilization has accordingly increased. The author discusses the various aspects of this method in relation to SPF animals and reports on the three years' experience of the Research Institute for Experimental Animal Breeding (University of Vienna) in Himberg with the use of exclusively radiation-treated diets in the rearing of rats and mice. The ease of handling irradiated fodder, the reliability of the method from the microbiological point of view and the excellent breeding results already obtained make this process - despite its somewhat higher cost - the best possible method of pasteurizing the feed of experimental animals.

  14. Amphibians as animal models for laboratory research in physiology.

    Science.gov (United States)

    Burggren, Warren W; Warburton, Stephen

    2007-01-01

    The concept of animal models is well honored, and amphibians have played a prominent part in the success of using key species to discover new information about all animals. As animal models, amphibians offer several advantages that include a well-understood basic physiology, a taxonomic diversity well suited to comparative studies, tolerance to temperature and oxygen variation, and a greater similarity to humans than many other currently popular animal models. Amphibians now account for approximately 1/4 to 1/3 of lower vertebrate and invertebrate research, and this proportion is especially true in physiological research, as evident from the high profile of amphibians as animal models in Nobel Prize research. Currently, amphibians play prominent roles in research in the physiology of musculoskeletal, cardiovascular, renal, respiratory, reproductive, and sensory systems. Amphibians are also used extensively in physiological studies aimed at generating new insights in evolutionary biology, especially in the investigation of the evolution of air breathing and terrestriality. Environmental physiology also utilizes amphibians, ranging from studies of cryoprotectants for tissue preservation to physiological reactions to hypergravity and space exploration. Amphibians are also playing a key role in studies of environmental endocrine disruptors that are having disproportionately large effects on amphibian populations and where specific species can serve as sentinel species for environmental pollution. Finally, amphibian genera such as Xenopus, a genus relatively well understood metabolically and physiologically, will continue to contribute increasingly in this new era of systems biology and "X-omics."

  15. Making animals alcoholic: shifting laboratory models of addiction.

    Science.gov (United States)

    Ramsden, Edmund

    2015-01-01

    The use of animals as experimental organisms has been critical to the development of addiction research from the nineteenth century. They have been used as a means of generating reliable data regarding the processes of addiction that was not available from the study of human subjects. Their use, however, has been far from straightforward. Through focusing on the study of alcoholism, where the nonhuman animal proved a most reluctant collaborator, this paper will analyze the ways in which scientists attempted to deal with its determined sobriety and account for their consistent failure to replicate the volitional consumption of ethanol to the point of physical dependency. In doing so, we will see how the animal model not only served as a means of interrogating a complex pathology, but also came to embody competing definitions of alcoholism as a disease process, and alternative visions for the very structure and purpose of a research field.

    Full Text Available There is documented evidence that infection in laboratory animals can often influence the outcome of experiments. All infections, apparent or inapparent, are likely to increase biological variability. As a research project concerning the diversity and distribution of parasites of rabbit and guinea pig in a conventional laboratory animal house, about 87 rabbits (from 700 and 105 guinea pigs (from 1500 were selected randomly from a Research, Production & Breeding of Laboratory Animals Department. Samples were collected between 19.02.2010 and 20.05.2011. The samples and animals were examined by dissection and flotation methods. In this study only one species of nematodes (Passalorus ambiguus: 6.9%; one species of protozoa (Eimeria spp.: 21.8% in rabbits and one species of nematodes (Paraspidodera Uncinata: 24.7%; one species of protozoa (Balantidium coli: 11.4% in guinea pigs were identified. However, there was not any cestodes or trematodes identified from this group of laboratory animals.

    With increasing globalization and a trend towards international harmonization of standards for the care and use of animals in research and testing,there is a significant need to assist and support countries to develop training programs for laboratory animal veterinarians. Although formal educational opportunities for training laboratory animal veterinarians exist through well-established specialty colleges of laboratory animal medicine such as ACLAM,ECLAM,JCLAM,and KCLAM or through other professional organisations,such as the Federation of European Laboratory Animal Science Associations ( FELASA ),opportunities for participating in these programs are often limited to veterinarians in North America,Western Europe and specific regions of Asia. Creative thinking is required to develop cost-effective,practical,entry-level and advanced continuing education and applied training programs for veterinarians working in the field of laboratory animal medicine around the world.This paper will describe one potential solution for this issue,the use of a distance education program that provides theoretical information in a virtual classroom with applied training modules to deliver knowledge and practical skills to laboratory animal veterinarians.This type of program takes advantage of the online learning environment and can be an effective means to deliver training at the grassroots level to adult learners.

  19. Mortality of atomic bomb survivors predicted from laboratory animals

    Carnes, Bruce A.; Grahn, Douglas; Hoel, David

    2003-01-01

    Exposure, pathology and mortality data for mice, dogs and humans were examined to determine whether accurate interspecies predictions of radiation-induced mortality could be achieved. The analyses revealed that (1) days of life lost per unit dose can be estimated for a species even without information on radiation effects in that species, and (2) accurate predictions of age-specific radiation-induced mortality in beagles and the atomic bomb survivors can be obtained from a dose-response model for comparably exposed mice. These findings illustrate the value of comparative mortality analyses and the relevance of animal data to the study of human health effects.

  20. Laboratory animal welfare: cage enrichment and mouse behaviour.

    Mice housed in standard cages show impaired brain development, abnormal repetitive behaviours (stereotypies) and an anxious behavioural profile, all of which can be lessened by making the cage environment more stimulating. But concerns have been raised that enriched housing might disrupt standardization and so affect the precision and reproducibility of behavioural-test results (for example, see ref. 4). Here we show that environmental enrichment increases neither individual variability in behavioural tests nor the risk of obtaining conflicting data in replicate studies. Our findings indicate that the housing conditions of laboratory mice can be markedly improved without affecting the standardization of results. PMID:15602544

    @@ Today's sophisticated biomedical research sometimes requires the use of laboratory animals raised in stable micronen vironments free from the microorganisms that may compromise the success of an experiment. Laboratory rodents can be obtained in one of several categories defined by the degree to which they harbour microflora, whether commensal, potentially pathogenic or pathogenic. It is now possible to specify the different species of organism that are tolerated and those that are not tolerated, In such model laboratory animals it is essential to raise and maintain them in circumstances under which microorganisms that would not be tolerated cannot enter the production system.

  6. Randomized block experimental designs can increase the power and reproducibility of laboratory animal experiments.

    Festing, Michael F W

    2014-01-01

    Randomized block experimental designs have been widely used in agricultural and industrial research for many decades. Usually they are more powerful, have higher external validity, are less subject to bias, and produce more reproducible results than the completely randomized designs typically used in research involving laboratory animals. Reproducibility can be further increased by using time as a blocking factor. These benefits can be achieved at no extra cost. A small experiment investigating the effect of an antioxidant on the activity of a liver enzyme in four inbred mouse strains, which had two replications (blocks) separated by a period of two months, illustrates this approach. The widespread failure to use these designs more widely in research involving laboratory animals has probably led to a substantial waste of animals, money, and scientific resources and slowed down the development of new treatments for human and animal diseases.

    A major shortcoming of the Animal Welfare Act is its exclusion of the species most-used in experimentation -- rats, mice, and birds. Considerations of justice dictate that extension of the law to these three species is the morally right thing to do. A brief history of how these species came to be excluded from the laws protecting laboratory animals is also provided, as well as discussion of the implications and significance of expanding the law.

    Laboratory animal is the animal with artificial feeding in the certain conditions, having the particular biological characteristics and for scientific research. They are indispensable props of life science and have made great contributions and sacrifices for human health and development. Laboratory animal science is an important branch of the life science,including laboratory animal and animal experiment. Along with development of mankind society, economy and civilization, now the realm of laboratory animal science is confronted with the problems of animal welfare and animal ethics.The animal protectionism inevitably conflict with the laboratory animal science in the certain way. People protect the wild animals first, then protect the artificially fed animal. Also people protect pets first and then protect the laboratory animals. Now it is popularization of protecting the wild and petted animals. It makes people hard to accept the reality of the experiments with animals. But life science especially biomedicine can't make great progress without the laboratory animals.

  15. The history of the oldest self-sustaining laboratory animal: 150 years of axolotl research.

    Science.gov (United States)

    Reiß, Christian; Olsson, Lennart; Hoßfeld, Uwe

    2015-07-01

    Today the Mexican axolotl is critically endangered in its natural habitat in lakes around Mexico City, but thrives in research laboratories around the world, where it is used for research on development, regeneration, and evolution. Here, we concentrate on the early history of the axolotl as a laboratory animal to celebrate that the first living axolotls arrived in Paris in 1864, 150 years ago. Maybe surprisingly, at first the axolotl was distributed across Europe without being tied to specific research questions, and amateurs engaged in acclimatization and aquarium movements played an important role for the rapid proliferation of the axolotl across the continent. But the aquarium also became an important part of the newly established laboratory, where more and more biological and medical research now took place. Early scientific interest focused on the anatomical peculiarities of the axolotl, its rare metamorphosis, and whether it was a larva or an adult. Later, axolotl data was used to argue both for (by August Weismann and others) and against (by e.g., Albert von Kölliker) Darwinism, and the axolotl even had a brief history as a laboratory animal used in a failed attempt to prove Lysenkoism in Jena, Germany. Nowadays, technical developments such as transgenic lines, and the very strong interest in stem cell and regeneration research has again catapulted the axolotl into becoming an important laboratory animal.

  20. Experience of radiation treatment of laboratory and farm animal feeds in Hungary

    International Nuclear Information System (INIS)

    The testing of methods suitable for the disinfection and sterilization of farm and laboratory animal feeds, and research into the effects of the methods on feeds and animals, started in Hungary within the last decade. Altogether, 871 tonnes of feeds sterilized and disinfected by various methods were used in 1976 for the feeding of farm and laboratory animals. Gamma radiation was used for sterilization of approx. 90 tonnes. Feeds for SPF animals were sterilized mainly at 1.5 Mrad, but 2.0-2.5 Mrad levels were also used. Feeds for germ-free animals were sterilized at a level of 4.5 Mrad. Experience gained over the past ten years has shown that irradiation at levels between 1.5 and 2.5 Mrad is excellent for the sterilization of mouse, rat, guinea pig and poultry feeds. Quality deterioration of the feeds remained slight and only slight decomposition of vitamins A and E and among the essential amino acids of lysine was observed. The irradiated feeds were readily consumed by the animals. In some cases, e.g. mice and rats, it was observed that weight gain in groups receiving irradiated diets exceeded that in groups fed on untreated or autoclaved diets, and at the same time the daily feed consumption in the groups receiving irradiated feed also increased. No adverse effect on reproduction and health of the farm and laboratory animals fed on irradiated feeds was observed. In Hungary the widespread use of feeds sterilized by irradiation is hindered, in spite of several advantages over feeds sterilized by conventional methods, mainly by the high cost of the irradiation and the supplemental costs associated with special packing and delivery. Therefore only a modest increase in the utilization of irradiated feeds can be expected in the next few years. (author)

    Simple Summary Millions of laboratory animals are killed each year worldwide. However, there is a lack of consensus regarding what methods of killing are humane for many species and stages of development. This report summarises research findings and discussions from an international meeting of experts and stakeholders, with recommendations to inform good practice for humane killing of mice, rats and zebrafish. It provides additional guidance and perspectives for researchers designing projects that involve euthanasing animals, researchers studying aspects of humane killing, euthanasia device manufacturers, regulators, and institutional ethics or animal care and use committees that wish to review local practice. Abstract Millions of laboratory animals are killed each year worldwide. There is an ethical, and in many countries also a legal, imperative to ensure those deaths cause minimal suffering. However, there is a lack of consensus regarding what methods of killing are humane for many species and stages of development. In 2013, an international group of researchers and stakeholders met at Newcastle University, United Kingdom to discuss the latest research and which methods could currently be considered most humane for the most commonly used laboratory species (mice, rats and zebrafish). They also discussed factors to consider when making decisions about appropriate techniques for particular species and projects, and priorities for further research. This report summarises the research findings and discussions, with recommendations to help inform good practice for humane killing. PMID:27563926

    Dedicated precise small laboratory animal irradiation sources are needed for basic cancer research and to meet this need expensive high precision radiation devices have been developed. To avoid such expenses a cost efficient way is presented to construct a device for partial body irradiation of small laboratory animals by adding specific components to an industrial X-ray tube. A custom made radiation field tube was added to an industrial 200 kV X-ray tube. A light field display as well as a monitor ionization chamber were implemented. The field size can rapidly be changed by individual inserts of MCP96 that are used for secondary collimation of the beam. Depth dose curves and cross sectional profiles were determined with the use of a custom made water phantom. More components like positioning lasers, a custom made treatment couch, and a commercial isoflurane anesthesia unit were added to complete the system. With the accessories described secondary small field sizes down to 10 by 10 mm{sup 2} (secondary collimator size) could be achieved. The dosimetry of the beam was constructed like those for conventional stereotactical clinical linear accelerators. The water phantom created showed an accuracy of 1 mm and was well suited for all measurements. With the anesthesia unit attached to the custom made treatment couch the system is ideal for the radiation treatment of small laboratory animals like mice. It was feasible to shrink the field size of an industrial X-ray tube from whole animal irradiation to precise partial body irradiation of small laboratory animals. Even smaller secondary collimator sizes than 10 by 10 mm{sup 2} are feasible with adequate secondary collimator inserts. Our custom made water phantom was well suited for the basic dosimetry of the X-ray tube.

    Real-time, or quantitative, polymerase chain reaction (qPCR) is quickly supplanting other molecular methods for detecting the nucleic acids of human and other animal pathogens owing to the speed and robustness of the technology. As the aquatic animal health community moves toward implementing national diagnostic testing schemes, it will need to evaluate how qPCR technology should be employed. This review outlines the basic principles of qPCR technology, considerations for assay development, standards and controls, assay performance, diagnostic validation, implementation in the diagnostic laboratory, and quality assurance and control measures. These factors are fundamental for ensuring the validity of qPCR assay results obtained in the diagnostic laboratory setting.

    With the sharp development of biomedicine, the protection and utilization of laboratory animal resources, and standardization of laboratory animal have been regarded as the theme of laboratory animal science. Many kinds of genetic markers were used in genetic background analysis, identification of species and strains, and breeding of laboratory animal, unlike morphological marker, cytological marker and isozyme marker, which revealed the difference at gene expressing level, molecular genetic markers used as an accurate and effective method reveal genetic variations of hereditary material, it plays an important role in many fields. The RAPD (Random Amplification Polymorphic DNA) method was firstly described in 1990, it has several distinct advantages over other techniques in that it is easy to perform and fast, and so was widely applied to taxonomy and identification of species, construction of genetic mapping, genetic relationships among species and population genetics. This paper summarized the application of RAPD markers in laboratory animal in recent 10 years.

    The Watase's shrew (Crocidura horsfieldi watasei), which is the native in the Nansei Islands in Japan, was entrapped, kept and mated in laboratory with the object of domestication. For the trapping of the animals hand-made traps were utilized, whereas pit-fall and Sherman trap were unsuitable. Keeping was easy in any types of cages which have no hole; through the holes the animals being able to escape. The animals were fed live insect or dry pelleted diet. Breeding was made by monogamous pair-mating, hand-mating or harem-mating method in the wooden cage. A total of 19 litters including 47 young were obtained from 5 monogamous pairs thus far. The litter size was 2.5 and the gestation period was estimated about 30 days. PMID:3735728

    The aim of the series of papers is to discuss the application of Xenopus laevis, as model animal in biology, in ecotoxicology. X. laevis as model animal is wildly used in biological study and has provided a lot of relating data because of many advantages, such as living in water and being easily maintained, laying eggs in the whole year, and externally fertilizing and developing. Embryos and larvae of X. laevis like other amphibians are directly exposed in the aquatic environment and sensitive to pollutants. In addition, sex differentiation and sex organ development of X. laevis are sensitive to sex hormones and endocrine disruptors with sex hormone activities, which enable X. laevis to be used in studies on sex hormone disruption and reproductive toxicity of endocrine disruptors. Metamorphic development of X. laevis is very sensitive to thyroid hormones and thyroid disruptors, which enables X. laevis to be used for evaluating thyroid disruptors. Also, X. laevis ecotoxicology can be linked with amphibian population declines and malformed frog occurrence, being one of the hotspots in ecology. Thus, more and more laboratories have introduced X. laevis to ecotoxicological study. The quality of laboratory animals correlates with scientificity and reliability of results from animal experiments. It is especially important for toxicology. Quality control of X. laevis involving several factors such as water and food is discussed in this paper.

  13. Near Field UHF RFID Antenna System Enabling the Tracking of Small Laboratory Animals

    Full Text Available Radio frequency identification (RFID technology is more and more adopted in a wide range of applicative scenarios. In many cases, such as the tracking of small-size living animals for behaviour analysis purposes, the straightforward use of commercial solutions does not ensure adequate performance. Consequently, both RFID hardware and the control software should be tailored for the particular application. In this work, a novel RFID-based approach enabling an effective localization and tracking of small-sized laboratory animals is proposed. It is mainly based on a UHF Near Field RFID multiantenna system, to be placed under the animals’ cage, and able to rigorously identify the NF RFID tags implanted in laboratory animals (e.g., mice. Once the requirements of the reader antenna have been individuated, the antenna system has been designed and realized. Moreover, an algorithm based on the measured Received Signal Strength Indication (RSSI aiming at removing potential ambiguities in data captured by the multiantenna system has been developed and integrated. The animal tracking system has been largely tested on phantom mice in order to verify its ability to precisely localize each subject and to reconstruct its path. The achieved and discussed results demonstrate the effectiveness of the proposed tracking system.

  14. Critical analysis for physical adaptation and implementation of new procedures in the IPEN'S laboratory animal division

    International Nuclear Information System (INIS)

    The production and the supply of high quality laboratory animals have fundamental importance for the accomplishment of vanguard scientific research, with reproducibility and universality. The quality of those animals depends, largely, of the available facilities for their production and lodging, to assure the demanded sanitary control and animals' welfare, in agreement with the ethical principles that control the activity. The facilities also have to fill out other requirements, such as: the functionality of the environments to make possible the suitable and efficient handling of the animals, facilitating the execution of the routine activities; the respect to ergonomic principles to provide a safe environment and the operators' well being. The facilities design is of vital importance so that the mentioned requirements can be reached. The project of the Nuclear and Energy Research Institute (IPEN) Animal House Facilities was accomplished in the year of 1964. However, by that time there were not the current recommendations with respect to the sanitary, genetic and environmental controls. The facility was planned with the objective of being a production unit and a local for keeping of defined animals from sanitary, genetic and environmental point of view. Nevertheless, the original unit drawing presents an unsuitable distribution of the area where animals are stocked and also different activities are performed. The Animal House Facilities occupy an area of 840 m2, with one pavement, where the production areas and the stock of original animal models of the own Institution are distributed, as well as the maintenance of animals from other national or foreigner institutions. It supplies rats and mice for biological tests of radiopharmaceutical lots, produced in IPEN, before they be sent to hospitals and clinics spread out in Brazil, for use in Nuclear Medicine. It also supplies rats and mice for tests of dental materials, for tests with growth hormones and for researches

    Virologists and other researchers who test pathogens for airborne disease transmissibility often place a test animal downstream from an inoculated animal and later determine whether the test animal became infected. Despite the crucial role of the airflow in modulating the pathogen transmission, to date the infectious disease community has paid little attention to the effect of airspeed or turbulence intensity on the probability of transmission. Here we present measurements of the turbulent dispersivity under conditions relevant to experimental tests of airborne disease transmissibility between laboratory animals. We used time lapse photography to visualize the downstream transport and turbulent dispersion of smoke particulates released from a point source downstream of a standard axial fan, thus mimicking the release and transport of expiratory aerosols exhaled by an inoculated animal. We demonstrate that the fan speed counterintuitively has no effect on the downstream plume width, a result replicated with a variety of different fan types and configurations. The results point toward a useful simplification in modeling of airborne disease transmission via fan-generated flows.

    This study was aimed to find out the host-parasite relationship between Paragonimus heterotremus isolated as metacercariae from mountain crabs, Indochinamon manipurensis, in Manipur, India and laboratory animals such as puppies, albino rats, Swiss mice, guinea pigs, and rabbits, as experimental animals. The animals were fed with the metacercariae. Infected animals were sacrificed 35 to 430 days after feeding to recover worms, which were used to determine the developmental stages. Adult worms (n = 14) were recovered from 3 puppies > or = 70 days after feeding and immature worms (n = 25) were recovered from 2 other puppies 35 or 43 days after infection. The infection rate in puppies was 100%. Juvenile worms were recovered from 3 of 13 rats: 1 of 11 rats whose viscera and cavities were examined and both of two rats whose muscles were examined. Rats were not a suitable animal model for pulmonary infection with P. heterotremus. Mice, guinea pigs, and rabbits were also found to be insusceptible to pulmonary infection with P. heterotremus.

    Dopaminergic synaptic function may be assessed either at the presynaptic terminal or at the postsynaptic binding sites using molecular in vivo imaging methods. Apart from the density of binding sites, parameters such as alterations in dopamine synthesis, dopamine storage or dopamine release can be quantified either by application of specific radiotracers or by assessing the competition between the exogenous radioligand and endogenous dopamine. The performance of animal studies allows the induction of specific short-term or long-term synaptic conditions via pharmacological challenges or infliction of neurotoxic lesions. Therefore, small laboratory animals such as rats and mice have become invaluable models for a variety of human disorders. This article gives an overview of those small animal studies which have been performed so far on dopaminergic neurotransmission using in vivo imaging methods, with a special focus on the relevance of findings within the functional entity of the dopaminergic synapse. Taken together, in vivo investigations on animal models of Parkinson's disease showed decreases of dopamine storage, dopamine release and dopamine transporter binding, no alterations of dopamine synthesis and DA release, and either increases or no alterations of D2 receptor binding, while in vivo investigations of animal models of Huntington's disease. showed decreases of DAT and D1 receptor binding. For D2 receptor binding, both decreases and increases have been reported, dependent on the radioligand employed. Substances of abuse, such as alcohol, amphetamine and methylphenidate, led to an increase of dopamine release in striatal regions. This held for the acute application of substances to both healthy animals and animal models of drug abuse. Findings also showed that chronic application of cocaine induced long-term reductions of both D1 and D2 receptor binding, which disappeared after several weeks of withdrawal. Finally, preliminary results yielded the first

    A portable 16-channels microcontroller-based wireless system for a bi-directional interaction with the central nervous system is presented in this work. The device is designed to be used with freely behaving small laboratory animals and allows recording of spontaneous and evoked neural activity wirelessly transmitted and stored on a personal computer. Biphasic current stimuli with programmable duration, frequency and amplitude may be triggered in real-time on the basis of the recorded neural activity as well as by the animal behavior within a specifically designed experimental setup. An intuitive graphical user interface was developed to configure and to monitor the whole system. The system was successfully tested through bench tests and in vivo measurements on behaving rats chronically implanted with multi-channels microwire arrays.

    Full Text Available In recent years, due to reduced training opportunities, the major shift in surgical training is towards the use of simulation and animal laboratories. Despite the merits of Virtual Reality Simulators, they are far from representing the real challenges encountered in theatres. We introduce the “Cattle Uterus Model” in the hope that it will be adopted in training courses as a low cost and easy-to-set-up tool. It adds new dimensions to the advanced hysteroscopic surgery training experience by providing tactile sensation and simulating intraoperative difficulties. It complements conventional surgical training, aiming to maximise clinical exposure and minimise patients’ harm.

    Charles River Laboratories Japan produces laboratory animals, mainly mice and rats. In its history, we have experienced many crises such as mass food poisoning of staff and contamination of animals. However, we overcame these crises, accomplishing our corporate missions to secure steady supply of healthy animals. Under such circumstances, in 2008, we faced an unprecedented crisis involving a novel influenza possibly becoming pandemic. Therefore, we prepared a Crisis Management Plan (CMP) and Business Continuity Plan (BCP) to avoid the worst case scenario. Fortunately, the novel influenza did not develop into a pandemic and no major problems occurred in production of our laboratory animals. In March 2011, our Tsukuba Breeding Center was struck by the Great East Japan Earthquake. Many cages fell from racks, and consequently, 14,000 mice and rats were euthanized. Moreover, this animal production facility experienced not only blackouts and water outage but also various maintenance problems. After triage of the animals, almost half of the animals kept were eventually lost. However, we recovered and resumed shipment of animals two weeks after the disaster by utilizing the CMP and BCP we initially created as a countermeasure against novel influenza. After two months, our production volume returned to normal except for two strains. I sincerely hope this review, which highlights our experience and related issues, will be a useful resource in regard to crisis management for people who are engaged in laboratory animal care and use.

    The 3Rs principle of replacement, reduction, and refinement has increasingly been endorsed by legislators and regulatory bodies as the best approach to tackle the ethical dilemma presented by animal experimentation in which the potential benefits for humans stand against the costs borne by the animals. Even when animal use is tightly regulated and supervised, the individual researcher's responsibility is still decisive in the implementation of the 3Rs. Training in laboratory animal science (LAS) aims to raise researchers' awareness and increase their knowledge, but its effect on scientists' attitudes and practice has not so far been systematically assessed. Participants (n = 206) in eight LAS courses (following the Federation of European Laboratory Animal Science Associations category C recommendations) in Portugal were surveyed in a self-administered questionnaire during the course. Questions were related mainly to the 3Rs and their application, attitudes to animal use and the ethical review of animal experiments. One year later, all the respondents were asked to answer a similar questionnaire (57% response rate) with added self-evaluation questions on the impact of training. Our results suggest that the course is effective in promoting awareness and increasing knowledge of the 3Rs, particularly with regard to refinement. However, participation in the course did not change perceptions on the current and future needs for animal use in research. PMID:23940123

    2015-01-01

    Accreditation of nonhuman animal research facilities by the Association for Assessment and Accreditation of Laboratory Animal Care International (AAALAC) is widely considered the "gold standard" of commitment to the well being of nonhuman animals used in research. AAALAC-accredited facilities receive preferential treatment from funding agencies and are viewed favorably by the general public. Thus, it bears investigating how well these facilities comply with U.S. animal research regulations. In this study, the incidences of noncompliance with the Animal Welfare Act (AWA) at AAALAC-accredited facilities were evaluated and compared to those at nonaccredited institutions during a period of 2 years. The analysis revealed that AAALAC-accredited facilities were frequently cited for AWA noncompliance items (NCIs). Controlling for the number of animals at each facility, AAALAC-accredited sites had significantly more AWA NCIs on average compared with nonaccredited sites. AAALAC-accredited sites also had more NCIs related to improper veterinary care, personnel qualifications, and animal husbandry. These results demonstrate that AAALAC accreditation does not improve compliance with regulations governing the treatment of animals in laboratories.

    Laboratory Animal Management Assistant (LAMA) is an internet-based system for tracking large laboratory mouse colonies. It has a user-friendly interface with powerful search capabilities that ease day-to-day tasks such as tracking breeding cages and weaning litters. LAMA was originally developed to manage hundreds of new mouse strains generated by a large functional genomics program, the Pleiades Promoter Project (http://www.pleiades.org). The software system has proven to be highly flexible, suitable for diverse management approaches to mouse colonies. It allows custom tagging and grouping of animals, simplifying project-specific handling and access to data. Finally, LAMA was developed in close collaboration with mouse technicians to ease the transition from paper- or Excel-based management systems to computerized tracking, allowing data export in a popular spreadsheet format and automatic printing of cage cards. LAMA is an open-access software tool, freely available to the research community at http://launchpad.net/mousedb. PMID:20411264

    2007-01-01

    This article examines several new and exciting communication technologies. Many of the technologies were developed by the entertainment industry; however, other industries are adopting and modifying them for their own needs. These new technologies allow people to collaborate across distance and time and to learn in simulated work contexts. The article explores the potential utility of these technologies for advancing laboratory animal care and use through better education and training. Descriptions include emerging technologies such as augmented reality and multi-user virtual environments, which offer new approaches with different capabilities. Augmented reality interfaces, characterized by the use of handheld computers to infuse the virtual world into the real one, result in deeply immersive simulations. In these simulations, users can access virtual resources and communicate with real and virtual participants. Multi-user virtual environments enable multiple participants to simultaneously access computer-based three-dimensional virtual spaces, called "worlds," and to interact with digital tools. They allow for authentic experiences that promote collaboration, mentoring, and communication. Because individuals may learn or train differently, it is advantageous to combine the capabilities of these technologies and applications with more traditional methods to increase the number of students who are served by using current methods alone. The use of these technologies in animal care and use programs can create detailed training and education environments that allow students to learn the procedures more effectively, teachers to assess their progress more objectively, and researchers to gain insights into animal care.

    International Nuclear Information System (INIS)

    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)

For developing gene-modified animals, the system is established for freeze-storing the ovum of those animals based on techniques of the micro-manipulation for external handling of ovum, in vitro fertilization (IVF) and early embryo culture. For preparing transgenic and/or knockout mice, embryos of 2-8 cell stages are usually freeze-stored. IVF/implanting fertilized ovum systems are also run for requests for storing the gene-modified ova and for supplying quickly many (up to about 100) animals. Techniques for freeze-storing unfertilized ova are to be established within this year. As well, the team is conducting the practical studies for the animals like genetic diagnoses of diseases and for the rapid supply of animals in accordance to research needs. (S.I.)

To compile these lists, BT members examined earlier published and unpublished reports, surveys, and data bases that pertained to the biota of this area or to areas that are similar. The species lists that are contained herein are compilations of the lists from these BAs, other lists that were a part of the initial research for the performance of these BAs, and more recent surveys.

  19. The role of laboratory animals in studying bone cancer resulting from skeletally deposited radionuclides

    International Nuclear Information System (INIS)

    There is a continuing need to determine and understand the long-term health risks of internally deposited radionuclides in persons exposed medically or occupationally, or from radionuclides in the environment. A full understanding of these health risks, particularly for exposures involving low doses and dose rates, requires in-depth knowledge of both the dosimetry of a given exposure and the resulting long-term biological effects. Human data on 224Ra and 226,228Ra and their decay products are our primary sources of knowledge on the health risks of chronic alpha irradiation of the skeleton and serve as essential segments of our radiation protection practices for internally deposited radionuclides. However, we cannot obtain all of the needed information from these studies. This paper examines the role of laboratory animal studies in complementing and extending the knowledge of radiation-induced bone cancer obtained from studies of humans exposed to 224Ra or 226,228Ra

    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.

    Since 1989, the National Institute for Occupational Safety and Health (NIOSH) considers the Laboratory Animal Allergy - LAA a risk for workers and in 1998 the LAA has been recognized as occupational risk in the USA. Rat and mouse are the most source of allergens, not so much for the higher power of allergy respect to the other animals, but because represent the more utilized species in the research. Most of the allergens are members of the lipocalin superfamily, small extracellular proteins represented by at least 50 proteins that mainly bind or carry small hydrophobic molecules. The recent and innovative molecular techniques, as the microarray, have allow the characterization of numerous allergens. The protein microarray gives the possibility to study of IgE profile for each individual, simultaneos analysis of a wide number of parameters concerning the allergy, giving new diagnostic and therapeutic opportunities for the allergies. In the study of occupational allergy--as LAA--the protein microarray could improve: the identification and characterization of new allergens; the individuation of susceptible workers; the study of immunological responses in exposed workers; the strategies of prevention and protection; the environmental and housing conditions. The participation, formation and information of the workers could improve the behavioural and occupational practices, the use of personal and collective protective devices in order to reduce the exposure to LAA in occupational context.

    Empathy, a basic prosocial behavior, is referred to as an ability to understand and share others' emotional state. Generally, empathy is also a social-behavioral basis of altruism. In contrast, impairment of empathy development may be associated with autism, narcissism, alexithymia, personality disorder, schizophrenia and depression. Thus, study of the brain mechanisms of empathy has great importance to not only scientific and clinical advances but also social harmony. However, research on empathy has long been avoided due to the fact that it has been considered as a distinct feature of human beings from animals, leading to paucity of knowledge in the field. In 2006, a Canadian group from McGill University found that a mouse in pain could be shared by its paired cagemate, but not a paired stranger, showing decreased pain threshold and increased pain responses through emotional contagion while they were socially interacting. In 2014, we further found that a rat in pain could also be shared by its paired cagemate 30 min after social interaction, showing long-term decreased pain threshold and increased pain responses, suggesting persistence of empathy for pain (empathic memory). We also mapped out that the medial prefrontal cortex, including the anterior cingulate cortex, prelimbic cortex and infralimbic cortex, is involved in empathy for pain in rats, suggesting that a neural network may be associated with development of pain empathy in the CNS. In the present brief review, we give a brief outline of the advances and challenges in study of empathy for pain in humans and animals, and try to provide a novel bio-psychosocial-behavioral model for study of pain and its emotional comorbidity using laboratory animals.

    Progress is reported on a broad and comprehensive series of biological experiments made under strictly controlled laboratory conditions to screen for possible effects of exposure to 60-Hz electric fields on small laboratory animals. Electric field strengths comparable to and exceeding those under existing and anticipated transmission line designs will be used. Dosimetry studies will complement the animal studies to establish the relationship between tissue dose and any observed biological effects. Information derived from this project will provide a better basis for evaluating potential hazards of exposure to 60-Hz electric fields and help define parameters to be studied in clinical evaluations on humans.

    Lawsonia intracellularis infection causes proliferative enteropathy (PE) in many mammalian species, with porcine and equine proliferative enteropathy (PPE and EPE) known worldwide. Hamsters are a well-published animal model for PPE infection studies in pigs. There is no laboratory animal model for EPE infection studies and it is not known whether there is species-specificity for equine or porcine isolates of L. intracellularis in animal models. The objective of this study was to determine whether it is possible to generate typical EPE lesions in hamsters after inoculation with an equine strain of L. intracellularis (EPE strain) and whether it is comparatively possible to generate PPE lesions in rabbits after inoculation with a porcine strain of L. intracellularis (PPE strain). In 2 separate trials, 4-week-old and 3-week-old weanling golden Syrian hamsters were challenged with EPE strains and compared to uninfected (both trials) and PPE-infected controls (Trial 2 only). Concurrently, 6 female New Zealand white juvenile rabbits were infected with PPE strain and observed concomitantly to 8 similar rabbits infected with EPE strain for a different experiment. Hamsters and rabbits were observed for 21 to 24 days post-infection (DPI), depending on the experiment. Neither infected species developed clinical signs. The presence of disease was assessed with diagnostic techniques classically used for pigs and horses: immune-peroxidase monolayer assay on sera; quantitative polymerase chain reaction (qPCR) detection of molecular DNA in feces; and hematoxylin and eosin (H&E) stain and immunohistochemistry (IHC) on intestinal tissues. Our results showed that EPE-challenged hamsters do not develop infection when compared with PPE controls (IHC, P = 0.009; qPCR, P = 0.0003). Conversely, PPE-challenged rabbits do not develop typical intestinal lesions in comparison to EPE-challenged rabbits, with serological response at 14 DPI being significantly lower (P = 0.0023). In conclusion

    The use of individually ventilated cage (IVC) systems has become an attractive housing regime of laboratory rodents. The benefits of IVC systems are, reportedly, a high degree of containment combined with relative ease of handling, and a high degree of protection from allergenes. In the present study we tested whether two IVC systems (BioZone VentiRack, IVC1 and Techniplast SealSafe, IVC2S), in which we held mature male NMRI mice, were constructed to maintain a constant differential pressure, positive or negative, during a prolonged period of time. We also measured ammonia (NH3) concentrations after about 2 weeks of use, and CO2 build-up during a 60 min simulated power failure situation. In addition, animal weight development and bite-wound frequency were recorded (Renström et al. 2000). From the present study it is concluded that the IVC1 air handling system provides a more uniform and balanced differential pressure than the IVC2S. Both systems effectively scavenge NH3 when bedding material is not soaked by urine. Although the IVCs are dependent on the continual function of the fans to work properly, it seems unlikely that CO2 concentrations increase to hazardous levels, as a result of a one hour power failure, with the type of cages used in this study. Differences in weight development and bite-wound occurrence were noted between the two IVC systems. Causes for these differences could not be established and need more investigation. PMID:11201288

  12. Self-harm in laboratory-housed primates: where is the evidence that the Animal Welfare Act amendment has worked?

    2011-01-01

    The 1985 amendment to the United States Animal Welfare Act (AWA) to promote psychological well being of primates in the laboratory represents an acknowledgment of an important welfare problem concerning nonhuman animals. How effective has this amendment been? Perhaps the best-known contributor to psychological distress in primates in the laboratory is nonsocial housing; yet, available analyses suggest that little progress has been made in avoiding single-caging of these animals. Another way to assess psychological well being is to examine rates of self-abusive behavior in laboratory primates. If the AWA has been effective, then post-AWA self-harm rates might be lower than pre-AWA rates. However, when we attempted to determine those rates from published studies, data were too sparse to allow a rigorous statistical analysis; of 139 studies reporting primate self-harming behavior, only 9 contained data allowing estimation of self-harming behavior rates. We conclude that the current system of laboratory animal care and record keeping is inadequate to properly assess AWA impacts on primate psychological well being and that more is required to ensure the psychological well being of primates.

    We have examined the genetic variability of Mycoplasma bovis strains submitted to the Pennsylvania Animal Diagnostics Laboratory, University Park (PA-ADL), between December 2007 and December 2008. Of 4,868 total samples submitted for Mycoplasma testing, 302 were determined to be culture positive. Mycoplasma bovis (63.6%), Mycoplasma californicum (7.3%), Mycoplasma bovirhinis (2.7%), Mycoplasma bovigenitalium (0.7%), Mycoplasma alkalescens (4.9%), Mycoplasma putrefaciens (0.3%), and Mycoplasma dispar (1.3%) and unidentified Mycoplasma sp. (19.2%) were identified using PCR. Mycoplasma bovis represented the largest portion of the positive samples submitted. Each of the 192 M. bovis isolates was examined for variations in the BglII and MfeI restriction sites of the DNA using amplified fragment length polymorphism fingerprinting and subsequently compared with the M. bovis type strain PG45 (ATCC 25523). Similarity between strains was calculated using the Dice similarity coefficient, which ranged from approximately 0.7 to 1.0. When clustering the isolates at greater than 95% similarity, it was determined that 11 distinct clusters were present. The results are consistent with the existence of at least 2 clonally distinct groups. No clear geographical, month of isolation, or source origination relationship was identified, indicating that a currently unclassified characteristic is responsible for the strain heterogeneity. These data indicate strong heterogeneity of M. bovis isolates submitted to PA-ADL. Additionally, multiple sites throughout Pennsylvania had isolates of separate clonal lineages present concomitantly, indicating the ability of multiple overlapping outbreaks to occur at a single location. Mycoplasma bovis represents the largest portion of Mycoplasma species isolated from PA-ADL samples. We propose that amplified fragment length polymorphism may serve as a valuable tool for molecular characterization of M. bovis strains from the United States. PMID:21426978

    Full Text Available Aim: To determine the carriage and antimicrobial resistance of Thermophilic Campylobacter species in the gastrointestinal tracts of farm and laboratory animals in Morogoro, Tanzania Materials and Methods: Faecal samples were collected from farm (n=244 and laboratory (n=466 animals and were subjected to the Cape Town protocol for isolation of Campylobacter. Isolates were preliminarily identified based on potassium hydroxide string and hippurate hydrolysis tests. Polymerase chain reaction (PCR was employed for confirmation of isolates. Antimicrobial resistance testing was done using disc diffusion method. Results: Of the laboratory animals 26.7% of guinea pigs (n=30 and 1.2% of rats (n=242 were colonized with Campylobacter. Four isolates from guinea pigs were Campylobacter jejuni and the other four were C. coli. From rats, two isolates were C. jejuni and one was C. coli. In farm animals thermophilic Campylobacter were detected from 31.6% of sheep (n=57 and 60% horses (n=5. Of the isolates 12 (57% were C. jejuni (10 from sheep and 2 from horses and the remaining were C. coli (8 from sheep and 1 from a horse. The isolates were frequently resistant to erythromycin, norfloxacin, colistin sulphate and nalidixic acid; whereas low levels of resistance were observed for ciprofloxacin and gentamicin. Conclusion: Our study reveals carriage of antimicrobial resistant thermophilic Campylobacter in the intestines of the study animals. This highlights possibilities in involvement of these animals in the epidemiology of Campylobacter infections. Thus, there is a need to consider these animal species when planning control measures for this zoonotic bacterium.

    2016-03-01

    Full Text Available In the past twenty years, evidence of neurotoxicity in the developing brain in animal studies from exposure to several general anesthetics has been accumulating. Propofol, a commonly used general anesthetic medication, administered during synaptogenesis, may trigger widespread apoptotic neurodegeneration in the developing brain and long-term neurobehavioral disturbances in both rodents and non-human primates. Despite the growing evidence of the potential neurotoxicity of different anesthetic agents in animal studies, there is no concrete evidence that humans may be similarly affected. However, given the growing evidence of the neurotoxic effects of anesthetics in laboratory studies, it is prudent to further investigate the mechanisms causing these effects and potential ways to mitigate them. Here, we review multiple studies that investigate the effects of in utero propofol exposure and the developmental agents that may modify these deleterious effects.

  20. Detection of alterations in testicular and epididymal function in laboratory animals

    Amann, R.P.

    The potential impact of an agent altering male reproductive function is greater for humans than for animals. Consequently, it is essential that sensitive criteria be used to look for effects on a multiplicity of target sites when an agent is evaluated using an animal model. No animal model has reproductive characteristics similar to those of humans, but this does not negate the validity of using animal models. Classic methodologies for reproductive toxicology are limited by the approaches used for subjective evaluation of testicular histology and use of natural mating for fertility tests. After dosing for an interval at least equal to six times the duration of one cycle of the seminiferous epithelium, sperm from ejaculated semen or the cauda epididymidis can be evaluated for normalacy of morphology or function and should be used for artificial insemination of females to critically evaluate fertility. Normal males of animals models ejaculate a great excess of sperm. Artificial insemination of a critical number of sperm, selected to result in slightly less than maximal fertility for control animals, will maximize the probability of detecting a decrease in fertility if the same critical number of sperm is inseminated for treated animals as for control animals. Testicular function should be evaluated by objective, rather than subjective, criteria. Among the more sensitive criteria of testicular function are the minor diameter of essentially round seminiferous tubules, the ratio of leptotene spermatocytes to Sertoli cells, the corrected numbers of germ cells per seminiferous tubule cross section, and the number of homogenization-resistant spermatids per testis.

    Full Text Available The aim of this work is to apply the plastination as an alternative method for protection on animals that are used in education, experiments and research according the European Directive 86/609/EEC. A two years old female guinea pig is used as material. The dissection of muscles as well subcutaneous structures and organs from abdominal cavity is preformed immediately after the death of animal. The guinea pig is plastinated using the protocol for S10 plastination. The plastinated guinea pig has firm consistention, it is dry on hand touch, oddorless and free of any chemical substances. The dissected skeletal muscle enable to learn their topography and easy to understand their function. Because of permanent preservation, the organs from abdominal cavity retain their topographical position enabling complete view of anatomical relationship of organs like stomach, spleen, pancreas and left kidney are, the mesenteries with apart of thin and large intestines, the relationship between the ovary and the horns of the uterus. According the results, the S10 plastination technique can be use for developing an anatomical model from one laboratory animal witch can be used for education process in anatomy. The method of plastination is an important tool allowing 3.R concept to be aplied and widely accepted since plastinated models can reduce using the laboratory animals for education and research purposes.

  5. Tracing water sources of terrestrial animal populations with stable isotopes: laboratory tests with crickets and spiders.

    Directory of Open Access Journals (Sweden)

    Kevin E McCluney

    Full Text Available Fluxes of carbon, nitrogen, and water between ecosystem components and organisms have great impacts across levels of biological organization. Although much progress has been made in tracing carbon and nitrogen, difficulty remains in tracing water sources from the ecosystem to animals and among animals (the "water web". Naturally occurring, non-radioactive isotopes of hydrogen and oxygen in water provide a potential method for tracing water sources. However, using this approach for terrestrial animals is complicated by a change in water isotopes within the body due to differences in activity of heavy and light isotopes during cuticular and transpiratory water losses. Here we present a technique to use stable water isotopes to estimate the mean mix of water sources in a population by sampling a group of sympatric animals over time. Strong correlations between H and O isotopes in the body water of animals collected over time provide linear patterns of enrichment that can be used to predict a mean mix of water sources useful in standard mixing models to determine relative source contribution.

    Fluxes of carbon, nitrogen, and water between ecosystem components and organisms have great impacts across levels of biological organization. Although much progress has been made in tracing carbon and nitrogen, difficulty remains in tracing water sources from the ecosystem to animals and among animals (the "water web"). Naturally occurring, non-radioactive isotopes of hydrogen and oxygen in water provide a potential method for tracing water sources. However, using this approach for terrestrial animals is complicated by a change in water isotopes within the body due to differences in activity of heavy and light isotopes during cuticular and transpiratory water losses. Here we present a technique to use stable water isotopes to estimate the mean mix of water sources in a population by sampling a group of sympatric animals over time. Strong correlations between H and O isotopes in the body water of animals collected over time provide linear patterns of enrichment that can be used to predict a mean mix of water sources useful in standard mixing models to determine relative source contribution. Multiple temperature and humidity treatment levels do not greatly alter these relationships, thus having little effect on our ability to estimate this population-level mix of water sources. We show evidence for the validity of using multiple samples of animal body water, collected across time, to estimate the isotopic mix of water sources in a population and more accurately trace water sources. The ability to use isotopes to document patterns of animal water use should be a great asset to biologists globally, especially those studying drylands, droughts, streamside areas, irrigated landscapes, and the effects of climate change.

  10. Invited review: Efficacy, metabolism, and toxic responses to chlorate salts in food and laboratory animals.

    2012-11-01

    For over 100 yr, scientists have explored uses of sodium chlorate in agricultural applications. Sodium chlorate is a strong oxidizer, and thus can be very hazardous when not handled accordingly. Nevertheless, late 19th century agriculturists and scientists attempted to exploit the chemical properties of sodium chlorate as an herbicide and food preservative. It is the herbicidal utility that led to subsequent use of sodium chlorate in the agricultural industry since then. However, in 2000, USDA-ARS scientists proposed a new and targeted use of sodium chlorate against enterobacteria in food animal production. Specifically, when orally dosed in to cattle (Bos taurus), swine (Sus scrofa), broilers (Gallus gallus), turkeys (Meleagris gallopavo), and sheep (Ovis aries), chlorate reduced the fecal shedding of common enteropathogens of the Enterobacteriaceae family. Subsequent to this discovery, the efficacy of chlorate salts has been demonstrated in numerous production classes within species. Doses of sodium chlorate as low as 30 mg/kg BW, but typically 50 to 150 mg/kg BW, have been used to demonstrate efficacy against pathogens. Single or short-duration (food animals. In all species studied to date, the major biotransformation product of chlorate is chloride ion; chlorite is not present in tissues or excreta of chlorate dosed animals. Chlorate is rapidly eliminated in ruminants and nonruminants, primarily in urine; likewise, residual chlorate in tissues depletes rapidly. Application of any new chemical entity to food animal production carries with it a responsibility to understand adverse reactions that intended and nonintended exposures may have in target and (or) nontarget animals and an understanding of the pathways of elimination that occur after exposure. Therefore, the purpose of this review is to summarize the published data regarding the efficacy, metabolism, and toxicology of chlorate salts in target (livestock) and nontarget species.

  12. Cytotoxic and pathogenic properties of Klebsiella oxytoca isolated from laboratory animals.

    Directory of Open Access Journals (Sweden)

    Alison Darby

    Full Text Available Klebsiella oxytoca is an opportunistic pathogen implicated in various clinical diseases in animals and humans. Studies suggest that in humans K. oxytoca exerts its pathogenicity in part through a cytotoxin. However, cytotoxin production in animal isolates of K. oxytoca and its pathogenic properties have not been characterized. Furthermore, neither the identity of the toxin nor a complete repertoire of genes involved in K. oxytoca pathogenesis have been fully elucidated. Here, we showed that several animal isolates of K. oxytoca, including the clinical isolates, produced secreted products in bacterial culture supernatant that display cytotoxicity on HEp-2 and HeLa cells, indicating the ability to produce cytotoxin. Cytotoxin production appears to be regulated by the environment, and soy based product was found to have a strong toxin induction property. The toxin was identified, by liquid chromatography-mass spectrometry and NMR spectroscopy, as low molecular weight heat labile benzodiazepine, tilivalline, previously shown to cause cytotoxicity in several cell lines, including mouse L1210 leukemic cells. Genome sequencing and analyses of a cytotoxin positive K. oxytoca strain isolated from an abscess of a mouse, identified genes previously shown to promote pathogenesis in other enteric bacterial pathogens including ecotin, several genes encoding for type IV and type VI secretion systems, and proteins that show sequence similarity to known bacterial toxins including cholera toxin. To our knowledge, these results demonstrate for the first time, that animal isolates of K. oxytoca, produces a cytotoxin, and that cytotoxin production is under strict environmental regulation. We also confirmed tilivalline as the cytotoxin present in animal K. oxytoca strains. These findings, along with the discovery of a repertoire of genes with virulence potential, provide important insights into the pathogenesis of K. oxytoca. As a novel diagnostic tool, tilivalline

    Full Text Available Human microsporidian infections have emerged following the onset of the AIDS pandemic. Microsporidia are unicellular eukaryotic parasites that form spores. They are an exceptionally diverse group of parasites that infect a wide range of eukaryotic cells in numerous invertebrate and vertebrate hosts. Of the 14 species newly described as pathogens in human, Enterocytozoon bieneusi, which causes gastrointestinal diseases, is the most common agent of human infections. In the past fifteen years, E. bieneusi was also identified in environmental sources, especially in surface water, as well as in wild, domestic and farm animals. These findings raised concerns for waterborne, foodborne and zoonotic transmission. Molecular analyses of the 243-bp internal Transcribed spacer-(ITS of the rRNA gene have revealed a considerable genetic variation within E. bieneusi isolates of human and animal origins, supporting the potential for zoonotic transmission. The focus of this revue is to present and discuss recent advances in diagnosis and zoonotic potential of E. bieneusi infections.

    Extramedullary hematopoiesis (EMH) is a pathological process secondary to underlying bone marrow (BM) insufficiency in adults. It is characterized by the emergence of multipotent hematopoietic progenitors scattered around the affected tissue, most likely in the spleen, liver, and lymph node, etc. EMH in patients frequently receives less medical attention and is neglected unless a compressive or obstructive hematopoietic mass appears to endanger the patient's life. However, on a biological basis, EMH reflects the alteration of relationships among hematopoietic stem and progenitor cells (HSPCs) and their original and new microenvironments. The ability of hematopoietic stem cells (HSCs) to mobilize from the bone marrow and to accommodate and function in extramedullary tissues is rather complicated and far from our current understanding. Fortunately, many reports from the studies of drugs and genetics using animals have incidentally found EMH to be involved. Thereby, the molecular basis of EMH could further be elucidated from those animals after cross-comparison. A deeper understanding of the extramedullary hematopoietic niche could help expand stem cells in vitro and establish a better treatment in patients for stem cell transplantation. PMID:25646951

    Full Text Available Hypothalamic peptidergic neurons using kisspeptin (KP and its co-transmitters for communication are critically involved in the regulation of mammalian reproduction and puberty. This article provides an overview of neuropeptides present in KP neurons, with a focus on the human species. Immunohistochemical studies reveal that large subsets of human KP neurons synthesize neurokinin B, as also shown in laboratory species. In contrast, dynorphin described in KP neurons of rodents and sheep is found rarely in KP cells of human males and postmenopausal females. Similarly, galanin is detectable in mouse, but not human, KP cells, whereas substance P, cocaine- and amphetamine-regulated transcript and proenkephalin-derived opioids are expressed in varying subsets of KP neurons in humans, but not reported in ARC of other species. Human KP neurons do not contain neurotensin, cholecystokinin, proopiomelanocortin-derivatives, agouti-related protein, neuropeptide Y, somatostatin or tyrosine hydroxylase (dopamine. These data identify the possible co-transmitters of human KP cells. Neurochemical properties distinct from those of laboratory species indicate that humans use considerably different neurotransmitter mechanisms to regulate fertility.

    Currently it is common practice to evaluate the developmental toxicity hazard of chemicals or pharmaceuticals by evaluation of fetuses after administration of the compound to pregnant animals. These studies are designed to provide possible compound-related fetal changes near term, which are usually classified into malformations or variations. Malformations, but not variations are expected to adversely affect the survival or health. Therefore, classification has striking different regulatory consequences. For categorization as variation reversibility is an important criterion, but it is usually not examined in a standard guideline study. Although this issue has already been recognized long time ago, data dealing with the postnatal reversibility of fetal alterations are still rare. In the current review, literature data, regulatory documents as well as in-house data were compiled. Beside skeletal alterations of skull, vertebral column, ribs, shoulder and pelvic girdle, and extremities, kidney and heart defects are discussed and assessed. PMID:27094378

    1992-04-01

    Some pharmacokinetic interactions between digoxin and amiodarone were studied in experiments on rabbits. An increase of digoxin serum levels was established in amiodarone-treated rabbits (amiodarone 30 mg/kg s.c. for five days alone or together with digoxin). The calculated elimination half-life (t 1/2) and the area under the curve (AUC) of digoxin were increased and the digoxin clearance was decreased, being most pronounced in animals receiving amiodarone-digoxin combination for five days. There were no changes either in digoxin toxicity in amiodarone-treated guinea pigs or in serum levels of T4, T3 and TTH. The possible mechanisms of digoxin-amiodarone interactions are discussed.

  2. Evans blue as a simple method to discriminate mosquitoes' feeding choice on small laboratory animals.

    Directory of Open Access Journals (Sweden)

    Ceres Maciel

    Full Text Available BACKGROUND: Temperature, humidity, vision, and particularly odor, are external cues that play essential roles to mosquito blood feeding and oviposition. Entomological and behavioral studies employ well-established methods to evaluate mosquito attraction or repellency and to identify the source of the blood meal. Despite the efficacy of such methods, the costs involved in the production or acquisition of all parts, components and the chemical reagents involved are unaffordable for most researchers from poor countries. Thus, a simple and relatively low-cost method capable of evaluating mosquito preferences and the blood volume ingested is desirable. PRINCIPAL FINDINGS: By using Evans blue (EB vital dye and few standard laboratory supplies, we developed and validated a system capable of evaluating mosquito's choice between two different host sources of blood. EB-injected and PBS-injected mice submitted to a number of situations were placed side by side on the top of a rounded recipient covered with tulle fabric and containing Aedes aegypti mosquitoes. Homogenates from engorged mosquitoes clearly revealed the blood source (EB- or PBS-injected host, either visually or spectrometrically. This method was able to estimate the number of engorded mosquitoes, the volume of blood ingested, the efficacy of a commercial repellent and the attractant effects of black color and human sweat. SIGNIFICANCE: Despite the obvious limitations due to its simplicity and to the dependence of a live source of blood, the present method can be used to assess a number of host variables (diet, aging, immunity, etc and optimized for several aspects of mosquito blood feeding and vector-host interactions. Thus, it is proposed as an alternative to field studies, and it could be used for initial screenings of chemical compound candidates for repellents or attractants, since it replicates natural conditions of exposure to mosquitoes in a laboratory environment.

    Objective: To investigate the phytochemical properties and the anticonvulsant potential of the ethyl acetate soluble fraction of ethanol leaf extract of Globimetula braunii, a plant used in ethnomedicine for the treatment of epilepsy. Methods:The phytochemical screening was carried out using standard protocol while the anticonvulsant activity was studied using maximal electroshock test in chicks, pentylenetetrazole and 4-aminopyridine-induced seizures in mice. Results: The preliminary phytochemical screening carried out on the crude ethanol extract revealed the presence of saponins, carbohydrates, flavonoids, tannins, anthraquinones and steroids. Similarly, tannins, flavonoids and steroids/terpenes were found to be present in the ethyl acetate fraction. In the pharmacological screening, 150 mg/kg of the fraction protected 83.33% of animals against pentylenetetrazole-induced seizure in mice whereas sodium valproate a standard anti-epileptic drug offered 100% protection. In the 4-aminopyridine-induced seizure model, the fraction produced a significant (P Conclusions:These results suggest that the ethyl acetate fraction of Globimetula braunii leaves extract possesses psychoactive compound that may be useful in the management of petit mal epilepsy and lend credence to the ethnomedical use of the plant in the management of epilepsy.

    A 3-month-old male cat in the animal facility was presented for investigation of anorexia and occasional vomiting. We collected the specimens from gastroscopic biopsy and stool collection. The gastroscopic biopsy specimens were tested using a rapid urease test, CLO Helicobacter-detection kits. Stool specimens were gathered and evaluated using the commercially available SD Bioline H. pylori Ag kit according to the manufacturer's instructions. Genomic DNAs from gastroscopic biopsy and stool specimens of the cat were extracted and submitted to the consensus PCR to amplify Helicobacter rpoB gene. Then the DNAs from gastroscopic biopsy and stool specimens were conducted a multiplex species-specific PCR to amplify urease B gene for H. heilmannii, H. pylori and H. felis. As the results, the rapid urease test with gastroscopic biopsy was revealed positive reaction. The result of H. pylori Stool Ag assay was one red line, negative for H. pylori. The gastroscopic biopsy and stool specimen were positive reactions by the consensus PCR reaction using the RNA polymerase beta-subunit-coding gene (rpoB) to detect Helicobacter species. By multiplex species-specific PCR with gastroscopic biopsy and stool specimens, no amplification products corresponding to either H. heilmannii or H. pylori were detected, but the specimens tested were positive for H. felis. This case was confirmed as gastroenteric disease induced by H. felis infection. On our knowledge, this is a very rare report about H. felis-induced gastroenteric disease in cat and may provide a valuable data on the study of feline Helicobacter infection. PMID:27382381

    Veterinary professionals working in partnership with other competent persons are essential for a successful animal care and use programme. A veterinarian's primary responsibilities are defined by their own professional regulatory bodies, but in this area of work there are further opportunities for contribution, which will assist in safeguarding the health and welfare of animals used in research. These guidelines are aimed not only at veterinarians to explain their duties, and outline the opportunities to improve the health and welfare of animals under their care, but also at employers and regulators to help them meet their responsibilities. They describe the desirability for postgraduate education towards specialization in laboratory animal medicine and detail the many competencies necessary to fulfil the role of the laboratory animal veterinarian. They detail the need for veterinary expertise to promote good health and good welfare of animals used in biomedical research during husbandry as well as when under experimental procedures. Regulatory and ethical aspects are covered as are the involvement of the veterinarian in education and training of others working in the animal care and use programme. Managerial aspects, including occupational health and safety, are also areas where the veterinarian's input can assist in the successful implementation of the programme.

    2011-01-01

    The new Directive 2010/63/EU on the protection of animals used for scientific purposes causes a need of several changes in German animal welfare law. On the basis of the regulations in the Directive, adjustments of the existing notification procedures are unavoidable. The Directive includes provisions for a simplified administrative procedure which differs significantly from the existing notification procedures. In any case, an application process will be required for projects in the meaning of the Directive. This contribution comments on the conceivable changes of the existing notification procedure. The implementation of the provisions of the Directive into national law has to be done near-term as the Directive is applicable from January 1st 2013. In advance, political and legal procedures must be passed through, the adapted regulations are to be notified by the European Commission and last but not least the authorities and user establishments must have enough time to implement the necessary changes.

  19. Environmental biochemistry of current environmental levels of heavy metals: preparation of radiotracers with very high specific radioactivity for metallobiochemical experiments on laboratory animals.

    1981-03-01

    Environmental toxicology research on dose-response relationships of heavy metals requires experiments on laboratory animals exposed to "low doses" of trace elements which should reflect "present or actual environmental levels" characteristic of polluted environments. Unfortunately no criteria exist to establish the "low doses" to which laboratory animals must be exposed, in practice the choice of the level used is made in an almost arbitrary manner. In order to define the "present environmental levels" of heavy metals which should be administered to laboratory animals an approach is suggested, based upon knowledge of the concentrations of trace elements in the diet, air and food as well as the fractions absorbed. Today daily intakes of trace elements by man are of the order of few micrograms or nanograms thus requiring the use of extremely sensitive analytical techniques to determine the very low amounts of heavy metals in tissues and cellular components. In these fields of research the use of radiotracers with very high specific radioactivity appears particularly advantageous but requires considerable care during their preparation and use. The first part of this paper deals with a definition of the ranges of concentrations of trace elements which should be used for metabolic studies on laboratory animals when they are exposed via different routes such as ingestion, inhalation in injection; the second part describes the production of radiotracers with very high specific radioactivity by proton activation in the cyclotron and by neutron irradiation in the nuclear reactor. Their use to label present levels of heavy metals under conditions adapted for biochemical purposes, as well as the preparation of different metal-labelled chemical species is also reported. Particular attention is directed to quality control of the radiotracer solutions which are administered to the animals including those of radioactivity concentrations, radioisotopic purity, radiochemical purity

    2015-05-01

    Scientific findings have revealed how much we have dramatically underestimated the intellectual, social and emotional capabilities of non-human animals, including their levels of self-consciousness and ability to suffer from psychological stress. In the 21st century, the field of animal ethics has evolved as a serious scientific discipline, and nowadays largely advocates that the way we treat animals, both legally and in practice, is morally wrong. Politics and legislation have reacted to these facts, to some extent, but neither current legislation nor current practice reflect the scientific and moral state-of-the-art. Too often, the will to change things is watered down in the decision-making process, e.g. in the drafting of legislation. In the field of animal experimentation there have been many genuine efforts by various players, to advance and apply the principles behind the Three Rs. However, the fundamental problem, i.e. the overall number of animals sacrificed for scientific purposes, has increased. Clearly, if we are serious about our will to regard animal experimentation as an ethical and societal problem, we have to put much more emphasis on addressing the question of how to avoid the use of animals in science. To achieve this goal, certain issues need to be considered: a) the present system of ethical evaluation of animal experiments, including testing for regulatory purposes, needs to be reformed and applied effectively to meet the legal and moral requirements; b) animal testing must be avoided in future legislation, and existing legislation has to be revised in that regard; c) resources from animal-based research have to re-allocated toward alternatives; and d) the academic curricula must be reformed to foster and integrate ethical and animal welfare issues.

    The effect of the dietary background of phytoestrogens on the outcome of rodent bioassays used to identify and assess the reproductive hazard of endocrine-disrupting chemicals is controversial. Phytoestrogens, including genistein, daidzein, and coumestrol, are fairly abundant in soybeans and alfalfa, common ingredients of laboratory animal diets. These compounds are weak agonists for the estrogen receptor (ER) and, when administered at sufficient doses, elicit an estrogenic response in vivo. ...

    Full Text Available In this work, biological effects of the water extract of Moringa oleifera seeds (WEMOS were assessed on eggs and 3rd instar larvae of Aedes aegypti and on its toxicity upon laboratory animals (Daphnia magna, mice and rats. Crude WEMOS showed a LC50 value of 1260µg/mL, causing 99.2 ± 2.9% larvae mortality within 24 h at 5200µg/mL, though this larvicidal activity has been lost completely at 80ºC/10 min. WEMOS did not demonstrate capacity to prevent egg hatching. After extensive dialyses of the crude WEMOS into watersoluble dialyzable (DF and nondyalizable (NDF fractions, only DF maintained its efficacy to kill larvae. Acute toxicity evaluations on daphnids (EC50 of 188.7µg/mL and mice (LD50 of 446.5 mg/kg body weight pointed out to low toxicity. Despite the thymus hypertrophy, WEMOS revealed to be harmless in orally and subacutelytreated rats. In conclusion, WEMOS has thermostable bioactive compounds against Ae. aegypti larvae with apparent molecular mass lower than 12 kDa and moderately toxic potential.Neste trabalho, o extrato aquoso das sementes de Moringaoleifera (EASMO foi avaliado quanto aos seus efeitos biológicos sobre ovos e larvas de Aedes aegypti no 3ºestágio de desenvolvimento e sua toxicidade sobre animais de laboratório(Daphnia magna, camundongos e ratos.

    Allometric scaling is widely used for the determination of first dosage regimen and the interpolation or extrapolation of pharmacokinetic parameters across many animal species during drug development. In this article, 85 drugs used in veterinary medicine obtained from the Food Animal Residue Avoidance Databank database were selected for allometric scaling analysis. Outlier species were identified by statistical methods. The results showed that 77% and 88% of drugs displayed significant correlations between total systemic clearance (CL) and volume of distribution at steady status (Vss) vs. body weight (P pharmacokinetic profiles for predicting drug dosages in veterinary species, and to identify those species for which interpolation or extrapolation of pharmacokinetics properties may be problematic.

    While comparing non-human primates with human beings, it is not hard to conclude certain similarities between these two based on aspects such as morphological anatomy, biochemistry functioning and so on. As a result, nonhuman primates often play an important role in life scientific researches. These primates are always used as "Stand-Ins"for human beings. In the processes of toxicological testing of new drugs, some drugs, especially drugs of genic projects or biological medicines are requiring uses of primates as part of the new drug testing. Therefore, the morality and ethics of using non-human primates have to be emphasised by people. After all, this is one of the issues that concerns with the expectations of meeting the international scientific research standards by our national laboratory animal sciences.In fact, the moral and ethical problems of non-human primates experiments is related to the matters of animal welfares.

  14. Do cage effects influence tumor incidence? An examination of laboratory animal carcinogenicity studies utilizing Fischer 344 rats.

    Haseman, J K

    1988-08-01

    Approximately 125 carcinogenicity studies in Fischer 344 rats conducted by the National Toxicology Program (NTP) were examined to determine the frequency with which cage effects were associated with observed carcinogenic responses. All studies involving groups of 50 rats housed five per cage and showing evidence of chemically-related carcinogenicity were considered. For each of these experiments, two statistical analyses were carried out for each dosed and control group: (i) a test to determine whether or not the occurrence of tumors clustered within cages; and (ii) an evaluation to determine whether or not tumor incidences differed significantly between differing cage shelf levels. These analyses showed that the numbers of statistically significant (P less than 0.05 or P less than 0.01) effects were consistent with the number expected by chance alone. Thus, cage-related factors appeared to have little or no impact upon tumor incidence in these particular studies. Experimental design protocols now used by the NTP (which include random assignment of animals to cages; random assignment of columns of cages to dosed and control groups; and periodic rotation of cage location) further reduce the likelihood that factors associated with the housing of the animals could influence tumor incidence in current studies.

    Eleven species of small African wild mammals, laboratory rabbits, guinea pigs, and Syrian hamsters were infected with Crimean-Congo hemorrhagic fever (CCHF) virus. Low-titered viremia followed by development of antibody was observed in scrub hares (Lepus saxatilis), Cape ground squirrels (Xerus inauris), red veld rats (Aethomys chrysophilus), white tailed rats (Mystromys albicaudatus), bushveld gerbils (Tatera leucogaster), striped mice (Rhabdomys pumilio), and guinea pigs. The maximum viremic titer in 4 scrub hares was 10(1.7-4.2) 50% mouse lethal doses/ml. Viremia was detected in 1/17 infected laboratory rabbits. Antibody response was only detected in South African hedgehogs (Atelerix frontalis), highveld gerbils (T. brantsii), Namaqua gerbils (Desmodillus auricularis), 2 species of multimammate mouse (Mastomys natalensis and M. coucha), and Syrian hamsters. The results of the study indicate that a proportion of infected scrub hares develop CCHF viremia of an intensity shown in the Soviet Union to be sufficient for infection of feeding immature ixodid ticks, but that South African hedgehogs and wild rodents are unlikely to be of importance as maintenance hosts of the virus in southern Africa.

    Adenovirus vaccine vectors generated from new viral serotypes are routinely screened in pre-clinical laboratory animal models to identify the most immunogenic and efficacious candidates for further evaluation in clinical human and veterinary settings. Here, we show that studies in a laboratory species do not necessarily predict the hierarchy of vector performance in other mammals. In mice, after intramuscular immunization, HAdV-5 (Human adenovirus C) based vectors elicited cellular and humoral adaptive responses of higher magnitudes compared to the chimpanzee adenovirus vectors ChAdOx1 and AdC68 from species Human adenovirus E. After HAdV-5 vaccination, transgene specific IFN-γ(+) CD8(+) T cell responses reached peak magnitude later than after ChAdOx1 and AdC68 vaccination, and exhibited a slower contraction to a memory phenotype. In cattle, cellular and humoral immune responses were at least equivalent, if not higher, in magnitude after ChAdOx1 vaccination compared to HAdV-5. Though we have not tested protective efficacy in a disease model, these findings have important implications for the selection of candidate vectors for further evaluation. We propose that vaccines based on ChAdOx1 or other Human adenovirus E serotypes could be at least as immunogenic as current licensed bovine vaccines based on HAdV-5.

  2. Suppression of Locomotor Activity in Female C57Bl/6J Mice Treated with Interleukin-1β: Investigating a Method for the Study of Fatigue in Laboratory Animals.

    Directory of Open Access Journals (Sweden)

    David R Bonsall

    Full Text Available Fatigue is a disabling symptom in patients with multiple sclerosis and Parkinson's Disease, and is also common in patients with traumatic brain injury, cancer, and inflammatory disorders. Little is known about the neurobiology of fatigue, in part due to the lack of an approach to induce fatigue in laboratory animals. Fatigue is a common response to systemic challenge by pathogens, a response in part mediated through action of the pro-inflammatory cytokine interleukin-1 beta (IL-1β. We investigated the behavioral responses of mice to IL-1β. Female C57Bl/6J mice of 3 ages were administered IL-1β at various doses i.p. Interleukin-1β reduced locomotor activity, and sensitivity increased with age. Further experiments were conducted with middle-aged females. Centrally administered IL-1β dose-dependently reduced locomotor activity. Using doses of IL-1β that caused suppression of locomotor activity, we measured minimal signs of sickness, such as hyperthermia, pain or anhedonia (as measured with abdominal temperature probes, pre-treatment with the analgesic buprenorphine and through sucrose preference, respectively, all of which are responses commonly reported with higher doses. We found that middle-aged orexin-/- mice showed equivalent effects of IL-1β on locomotor activity as seen in wild-type controls, suggesting that orexins are not necessary for IL-1β -induced reductions in wheel-running. Given that the availability and success of therapeutic treatments for fatigue is currently limited, we examined the effectiveness of two potential clinical treatments, modafinil and methylphenidate. We found that these treatments were variably successful in restoring locomotor activity after IL-1β administration. This provides one step toward development of a satisfactory animal model of the multidimensional experience of fatigue, a model that could allow us to determine possible pathways through which inflammation induces fatigue, and could lead to novel

    A high-throughput method for the determination of 28 mycotoxins involving pressurised liquid extraction (PLE) coupled with liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) has been optimised and validated for determination in various biological fluids and tissues of human and laboratory animals. High-throughput analysis was achieved using PLE pre-treatment and without the need for any cleanup. The extraction solvent was acetonitrile/water/acetic acid (80/19/1, v/v/v). The static extraction time was 5min. The extraction pressure and temperature were 1500psi and 140°C, respectively. The flush volume was 60%. The limits of detection, which were defined as CCα, varied from 0.01μg/kg (μg/L) to 0.69μg/kg (μg/L). The recoveries of spiked samples from 0.20μg/kg (μg/L) to 2μg/kg (μg/L) ranged from 71% to 100.5% with relative standard deviations of less than 17.5%, except FB1 and FB2 recoveries, which were lower than 60%. The method was successfully applied in real samples, and the data indicate that this technique is a useful analytical method for the determination of mycotoxins from humans and animals. To the best of our knowledge, this method is the first for the large-scale testing of multi-class mycotoxins in all types of biological fluids and tissues that uses PLE and HPLC-MS/MS.

  4. Lifetime radiation effects research in animals: An overview of the status and philosophy of studies at University of California-Davis Laboratory for Energy-Related Health Research

    International Nuclear Information System (INIS)

    Studies on the life-shortening and carcinogenic effects of internal emitters and external irradiation have been conducted at the Laboratory for Energy-Related Health Research for over three decades. Our principal animal model has been the beagle dog. The beagle's tissue sensitivity, metabolic and dosimetric characteristics, pathologic responses, and aging changes give it relevance for the assessment of radiation risks in humans. Although our results confirm the existence of an amelioration of effects at low doses and low dose rates (the dose-rate effectiveness factor), the manifestation of the amelioration may vary. For example, with x-irradiation higher exposures appeared to decrease latency but did not alter the incidence of mammary cancer, whereas with the bone-seeking radionuclides, 90Sr and 226Ra, higher doses decreased the latency and increased the incidence of osteosarcomas. Radiation-induced leukemias were seen only with high doses at high dose rates but only from 90Sr and from chronic exposures to 60Co, mainly in dogs exposed beginning in utero. Most of the radiation-induced life shortening in dogs exposed to internal emitters appears attributable to an increased cancer risk, but this is not necessarily the case for x-irradiated dogs

    Laboratory animal is the animal with artificial feeding in the certain conditions, having the particular biological characteristics for scientific research. They are indispensable props of life science and have made great contributions and sacrifices for human health and development. Laboratory animal science is an important branch of life science, including laboratory animal and animal experiment. Along with development of mankind society, economy and civilization, now the realm of laboratory animal science is confronted with the problems of animal welfare and animal ethics. In our country, the main problems of animal welfare and animal ethics in laboratory animal science lie below: relative rules and laws are absent, while no established restriction or punishment could be found to restrict those actions such as maltreating laboratory animals. Several technical operations going against laboratory animal ethics still exist. The emotional conflicts also exist between zoophilists and animal experimenters. The appearance of animal ethic in China is mainly due to the rapid progress of the national economy and that of the international relationship at the same time, and the education in these years, which promoted communications between cultures from East and West, by the way changed social opinions greatly. Since recent more than ten years, animal ethic research has achieved great development at the laboratory animal science field in our country. The appearance of the laboratory animal monuments and import of the "3R" theory serve as the main indication of the great development that achieved. Such things are our goals: improving living conditions of laboratory animals, forbidding the phenomenon of maltreating laboratory animals to death, standardizing the rules of operation on animal experiments, establishing correlate laws and polices, founding the committee of animal ethics and group of specialists, consolidating international communion, promoting the development of

    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. PMID:24660572

    If the content of an element in hair of an individual is used for the assessment of health risk of that person it is of special importance to know if the hair analytical data reflect the body burden or the content of the organ or tissues at risk. Ideally the content in hair should rise and fall in parallel to an increase or decrease of the body burden or the content in the critical organs. It was the aim of this project to study the transfer of Hg, methyl-mercury and Zn to hair and to compare it with the levels simultaneously observed in the total body and the relevant organs under controlled experimental conditions in an animal model. In addition, a similar study on As and the analyses of two experiments of a long term study on Cd exposure were also included. 11 refs, 3 figs, 4 tabs

    From February 25 to 26, 2010, in San Francisco, the Resource for Biocomputing, Visualization, and Informatics (RBVI) and the National Center for Macromolecular Imaging (NCMI) hosted a molecular animation workshop for 21 structural biologists, molecular animators, and creators of molecular visualization software. Molecular animation aims to visualize scientific understanding of biomolecular processes and structures. The primary goal of the workshop was to identify the necessary tools for producing high-quality molecular animations, understanding complex molecular and cellular structures, creating publication supplementary materials and conference presentations, and teaching science to students and the public. Another use of molecular animation emerged in the workshop: helping to focus scientific inquiry about the motions of molecules and enhancing informal communication within and between laboratories.

    Pavlov and Thorndike pioneered the experimental study of animal learning and provided psychologists with powerful tools to unveil its underlying mechanisms. Today's research developments and theoretical analyses owe much to the pioneering work of these early investigators. Nevertheless, in the evolution of our knowledge about animal learning, some initial conceptions have been challenged and revised. We first review the original experimental procedures and findings of Pavlov and Thorndike. Next, we discuss critical research and consequent controversies which have greatly shaped animal learning theory. For example, although contiguity seemed to be the only condition that is necessary for learning, we now know that it is not sufficient; the conditioned stimulus (CS) also has to provide information about the occurrence of the unconditioned stimulus (US). Also, animals appear to learn different things about the same stimuli when circumstances vary. For instance, when faced with situations in which the meaning of a CS changes, as in the case of acquisition and later extinction, animals seem to preserve the original knowledge (CS-US) in addition to learning about the new conditions (CS-noUS). Finally, we discuss how parallels among Pavlovian conditioning, operant conditioning, and human causal judgment suggest that causal knowledge may lie at the root of both human and animal learning. All of these empirical findings and theoretical developments prove that animal learning is more complex and intricate than was once imagined. Copyright © 2009 John Wiley & Sons, Ltd.

  19. 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.

  2. Separation of haemopoietic cells for biochemical investigation. Preparation of erythroid and myeloid cells from human and laboratory-animal bone marrow and the separation of erythroblasts according to their state of maturation.

    Harrison, F L; Beswick, T M; Chesterton, C J

    1981-03-15

    The separation of haemopoietic bone-marrow cells by centrifugation through discontinuous density gradients of Percoll is described. This method was used to prepare fractions enriched in erythroblasts, myeloid blast cells or reticulocytes from bone marrow of anaemic and non-anaemic rabbits, from the marrow of other anaemic laboratory animals and from human samples. It is a simple, rapid, reproducible and inexpensive technique that can be readily adapted to suit individual requirements. Secondly, a convenient method is presented for the separation of large quantities of bone-marrow cells into fractions enriched in erythroblasts at different stages of maturation, by velocity sedimentation through a linear gradient of 1-2% sucrose at unit gravity. In vitro, erythroblasts adhere together strongly via a mechanism almost certainly involving a beta-galactoside-specific surface lectin termed erythroid developmental agglutinin. Since the efficiency of cell-separation techniques depends heavily on the maintenance of a single cell suspension in which each unit can move independently, the presence of an adhesive molecule at the cell surface is of considerable significance. The effect of washing the marrow with a lactose-containing medium, which has been shown to remove the agglutinin, was therefore investigated in relation to both methods. The separation on Percoll gradients is considerably enhanced by this treatment. In addition, the unit-gravity sedimentation gradient can be loaded with 5-10 times more cells after lactose extraction in comparison with intact marrow. Although enrichment is less, a useful fractionation according to maturation is still obtained.

    Many of us think that all wild animals are dangerous. In fact, very few of them will eat a man if he leaves them alone. If you meet a tiger, I'm sure you will run away, but even a tiger doesn't like meeting a man if it isn't hungry. Tigers only kill and eat man when they are too old to catch their food, such as sheep and other small animals. Some animals get frightened when they only smell a man. Some of themst and and look at a man for a short time before they run away.

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......, indeed, can be considered a social/ emotional learning media, which goes beyond the limitations of live action movies. This is due to the diversity of techniques, and its visual plasticity that constructs the impossible. Animators are not real actors but more like the midwife who brings the anima...... into aliveness, which requires knowing how emotions work. Ed Hooks as an expert in training animators and actors, always remarks: “emotions tend to lead to action”. In this paper we want to argue that by producing animated films, as we watch them, cause a stronger effect, not only in our brains, but also in our...

Methods Kunming mice at 6 weeks of age were inoculated with the suspension of sheep-derived Echinococcus granulosus protoscolices in the abdomen. New Zealand rabbits were inoculated with the suspension of sheep-derived Echinococcus granulosus protoscolices in the liver after surgical operation in the abdominal region. The hydatid cysts in the animals were observed by naked eyes and optical microscopy in 6 months after inoculation. Results At the observation time point, the hydatid cysts were found in the abdominal cavities of 95% experimental mice (19/20) and in the liver of 50% experimental rabbits (4/8). Compared with those derived from the sheep liver, the hydatid cysts had similar epithelioid cell layer and lamellar structure but thinner cyst wall. Protoscolices were found in the hydatid cysts derived from all animals. Conclusion The animal models of hydatid disease can be established by inoculating mice and rabbits with the suspension of Echinococcus granulosus

    Objective To obtain histological data of the respiratory organs of laboratory animals and provide standard reference data for pathological inspection, toxicological studies and drug safety evaluation. Methods Thirty ordinary adult rhesus monkeys, 20 KM mice, 20 SD rats, 18 Japanese white rabbits, 16 Beagle dogs, and 20 Tupaia belangeri were included in this study. After intravenous anesthesia, the animals were sacrificed by femoral artery bleeding,and the trachea and lungs were removed, fixed in 10% formalin, and paraffin sections were stained with HE. The histological structure of the trachea and lungs was observed by light microscopy. The similarities and differences of the trachea and lung structures were compared among the different animal species. Results ( 1 ) The goblet cells in the tracheal epithelium; There were more goblet cells in the Beagle dogs and Japanese white rabbits than in the SD rats, KM mice and Tupaia belangeri, and their secretion was mainly neutral mucus in most animal species, but neutral and acidic mucus in Beagle dogs. (2) Distribution of submucosal glandular acini; There were most numerous submucosal glandular acini in the Beagle dogs, less numerous in the rhesus monkeys, SD rats, KM mice, and Tupaia belangeri, and least acini of submucosal mixed glands in the Japanese white rabbits. (3) The bronchial branches; The bronchial tree in the Beagle dogs, rhesus monkeys and Japanese white rabbits was composed of lobar bronchi, segmental bronchi, small bronchi, bronchioles, terminal bronchioles and respiratory bronchioles. In the SD rats, KM mice and Tupaia belangeri, it was composed of only bronchioles, terminal bronchioles and respiratory bronchioles. (4) Histological structure of bronchioles; The bronchioles of Beagle dogs and rhesus monkeys had an intact circular smooth muscle layer, which was a thin circular layer or lack of it in the SD rats, KM mice, Tupaia belangeri and Japanese white rabbits. There was a small amount of goblet cells in

    [figure removed for brevity, see original site] Click on image for animation This is an animation of the Canadian-built meteorological station's lidar, which was successfully activated on Sol 2. The animation shows how the lidar is activated by first opening its dust cover, then emitting rapid pulses of light (resembling a brilliant green laser) into the Martian atmosphere. Some of the light then bounces off particles in the atmosphere, and is reflected back down to the lidar's telescope. This allows the lidar to detect dust, clouds and fog. 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.

    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.

    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.

    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. However, the progress is slower than anticipated, mainly because of the difficulty involved in identifying genes that control phenotypic characteristics of importance to the animal industry.

    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.

  11. An animal welfare perspective on animal testing of GMO crops.

    Science.gov (United States)

    Kolar, Roman; Rusche, Brigitte

    2008-01-01

    The public discussion on the introduction of agro-genetic engineering focuses mainly on economical, ecological and human health aspects. The fact is neglected that laboratory animals must suffer before either humans or the environment are affected. However, numerous animal experiments are conducted for toxicity testing and authorisation of genetically modified plants in the European Union. These are ethically questionable, because death and suffering of the animals for purely commercial purposes are accepted. Therefore, recent political initiatives to further increase animal testing for GMO crops must be regarded highly critically. Based on concrete examples this article demonstrates that animal experiments, on principle, cannot provide the expected protection of users and consumers despite all efforts to standardise, optimise or extend them.

Furthermore, they usually claim that this animal interest in liberty is intrinsic rather than instrumental; that is to say, liberty is regarded to be good for animals in itself, irrespective of its contribution to the achievement of other goods, such as pleasure. For this reason they argue that legislating to improve welfare standards in zoos, circuses, laboratories and agriculture is inadequate....

  16. Decerebrate rigidity in animals.

    Science.gov (United States)

    Davis, R A; Davis, L

    1981-07-01

    Decerebrate rigidity (DR) in animals is caused by a release of spinal neurons from supraspinal inhibition, which results in a caricature of reflex standing and includes tonic neck and labyrinthine reflexes. The reticular formation, cerebellum, vestibular complex, spinal cord, and muscle spindle system and their neurophysiological interaction are critical to DR. Its discovery and investigation were essential to Sherrington's concept of the integrative action of the nervous system. There are two types of DR with different anatomical and physiological bases. Intercollicular decerebration yields rigidity in extensor muscles that results from bilateral destruction of the central tegmental tracts, is abolished by posterior root section, and is due to a facilitation of gamma motoneuron discharge (gamma animal). Anemic decerebration is characterized by excessive extensor rigidity, depends upon the release of tonic labryinthine reflexes from cerebellar inhibition, is independent of posterior root section, and is caused by excessive alpha motoneuron discharge (alpha animal). DR has provided an insight into the mechanisms of posture and standing, but the correlation of laboratory observations and results from animals to humans must be made with caution.

    Rat and squirrel monkeys experiments have been planned in concert with human experiments to help answer fundamental questions concerning the effect of weightlessness on mammalism 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 vertibrate development. Following these preliminary animal experiments on Spacelab Shuttle flights, longer term programs of animal investigation will be conducted on Space Station.

Various research projects in the field of fixation of fractures, development of newer biomaterials, chemotherapeutic drugs, use of stem cells in nonunion of fractures and cartilage defects etc., have hugely depended on animal experimentation. The employment of animals in experiments is both scientific and ethical issue. There must be reasonable reasons to show that it will significantly advance the present knowledge and lead to improvement in care. The regulatory bodies exist for humane use and care of animals used for experiments e.g., International Council for Laboratory Animal Science, Council for International Organizations of Medical Sciences, International Union of Biological Sciences, International Committee on Laboratory Animals. In India, Indian National Science Academy, Indian Council of Medical Research, National Centre for Laboratory Animal Sciences promote high standards of laboratory animal quality, care and health.

    As described by Lori Gruen in the Perspective column at the back of this issue, federally supported biomedical research conducted on chimpanzees has now come to an end in the United States, although the wind-down has taken longer than expected. The process began with a 2011 Institute of Medicine report that set up several stringent criteria that sharply limited biomedical research. The National Institutes of Health accepted the recommendations and formed a committee to determine how best to implement them. The immediate question raised by this transition was whether the IOM restrictions should be extended in some form to other nonhuman primates-and beyond them to other kinds of animals. In the lead article in this issue, Anne Barnhill, Steven Joffe, and Franklin Miller consider the status of other nonhuman primates. PMID:27417859

    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.

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

    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.

  10. Animating Brains

    Borck, Cornelius

    2016-01-01

    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

    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.

  19. Animal models for human diseases.

    Science.gov (United States)

    Rust, J H

    1982-01-01

    The use of animal models for the study of human disease is, for the most part, a recent development. This discussion of the use of animal models for human diseases directs attention to the sterile period, early advances, some personal experiences, the human as the model, biological oddities among common laboratory animals, malignancies in laboratory animals, problems created by federal regulations, cancer tests with animals, and what the future holds in terms of the use of animal models as an aid to understanding human disease. In terms of early use of animal models, there was a school of rabbis, some of whom were also physicians, in Babylon who studied and wrote extensively on ritual slaughter and the suitability of birds and beasts for food. Considerable detailed information on animal pathology, physiology, anatomy, and medicine in general can be found in the Soncino Babylonian Talmudic Translations. The 1906 edition of the "Jewish Encyclopedia," has been a rich resource. Although it has not been possible to establish what diseases of animals were studied and their relationship to the diseases of humans, there are fascinating clues to pursue, despite the fact that these were sterile years for research in medicine. The quotation from the Talmud is of interest: "The medical knowledge of the Talmudist was based upon tradition, the dissection of human bodies, observation of disease and experiments upon animals." A bright light in the lackluster years of medical research was provided by Galen, considered the originator of research in physiology and anatomy. His dissection of animals and work on apes and other lower animals were models for human anatomy and physiology and the bases for many treatises. Yet, Galen never seemed to suggest that animals could serve as models for human diseases. Most early physicians who can be considered to have been students of disease developed their medical knowledge by observing the sick under their care. 1 early medical investigator

    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 interpr...

  20. Animal husbandry and experimental design.

    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.

    In Hungary, the first Act on Animal Protection, which aimed at handling and respecting animals as living creatures capable of feelings and suffering and thus deserving and entitled to protection, was adopted in 1998. Based on this, the Act contains several regulations which ensure that animals are protected against all possible kinds of avoidable physical or mental harm. Furthermore, it prohibits and imposes sanctions for any treatment that causes animals unnecessary suffering. The present st...

    These are two separate, side-by-side animations made from the same nine images the Surface Stereo Imager (SSI) on NASA's Phoenix Mars Lander took looking into the sky after 5:17 p.m. local time on Sol 8 (June 2, 2008), the eighth Martian day of the mission. The SSI was pointed almost straight up, toward the southwest. Zenith is near the top of the center frame. In the left animation, the images were stretched to enhance contrast. The right animation highlights variations between each image and the next. The variations are likely dust blown by winds passing through the SSI's field of view. The images suggest the dust is blowing from west to east. 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. Spacecraft development is by Lockheed Martin Space Systems, Denver.

  6. MICE, a program to track and monitor animals in animal facilities

    Full Text Available Abstract Background A growing number of laboratories are using the mouse as a model system in developmental biology as well as in molecular biology. Surprisingly, most of these laboratories do not have reliable computerized systems to track these animals, and the few commercial solutions available are expensive. We thus developed MICE (Mouse Information and Classification Entity, a program aimed at facilitating the monitoring of animals in animal facilities. Results This program consists of a virtual facility in which scientists can perform all the tasks done in the real world (i.e., receiving animals, breeding them, preparing cage labels, etc.. Recording of each animal (birth date, cage number, ID number, tail analysis number, parents, genetic status, genetic background, etc. enables reliable tracking. According to any parameter of interest, animals can then be identified, grouped, sorted, moved, and so forth. Crossings are automatically processed by the program. For example, new genetic backgrounds, generation number, and anticipated due dates are determined. The program also reminds the user when new births are expected and entering newborn animals only requires a few clicks. The genealogy of each animal can be determined in two different ways, one being the visualization of a genealogical tree from which information of ancestors can be retrieved. Conclusion This standalone program, that will be distributed free of charge to academic laboratories requesting a license, represents a new and valuable tool for all animal facility users, and permits simple and reliable tracking and retrieving of animals.

    Full Text Available Pese a los avances realizados en los últimos años, el dolor neuropático constituye aún un serio problema asistencial. Los tratamientos disponibles sólo permiten aliviar adecuadamente un tercio de los pacientes. Los modelos experimentales pueden contribuir a conocer la fisiopatología de este cuadro clínico, así como a probar nuevos fármacos. Existen básicamente dos tipos de modelos, aquellos que realizan una lesión en el nervio periférico y los que causan alteraciones en el sistema nervioso central. A pesar de sus limitaciones, los modelos animales pueden contribuir a avanzar en el conocimiento de este síndrome y algunos de ellos pueden ayudar a predecir la utilidad terapéutica de nuevos medicamentos. Obviamente, sólo los ensayos clínicos bien diseñados permitirán conocer su eficacia real en el ámbito clínico.In spite of the advancement of pain research in the last decade, the therapy of neuropathic pain is still an unresolved issue. Available treatments only adequately improve only a third of patients. Experimental models may contribute to the knowledge of its pathophysiology, as well as to the development of new drugs. Basically, two types of animal models are available: those that cause a lesion in the peripheral nerves and those that injury the central nervous system. Beyond these limitations, animal models may help to improve the knowledge of neuropathic pain and some of them have predictive value on the usefulness of analgesic efficacy of new drugs. Obviously, only well-designed, controlled clinical trials will permit to establish their actual efficacy in the clinical setting.

    2016-01-01

    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....

    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.

    1995-01-01

    Animal rights movements have increased the scope and intensity of their activities over the past decade. While it is generally assumed that doctors and other members of the health care professions favour the use of animals for science, few data are available. Student protests in various medical schools against use of animals in teaching laboratories indicated further need for objective data. A questionnaire about attitudes to the use of animals for teaching purposes was distributed to all the medical students at the Ben-Gurion University of the Negev, present during classes on a given day. All students present (200) returned the questionnaire (70% of the student body). Also queried were attitudes towards related subjects. A high percentage of medical students surveyed had significant reservations about animal experimentation for teaching purposes and about the preferential priority for human life over that of animals. These attitudes, if confirmed, have serious implications for educators both in the health fields and otherwise. PMID:7623684

    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.

    Full Text Available Interactions that animals experience can have a significant influence on their health and welfare. These interactions can occur between animals themselves, but also between animals and keepers, and animals and the public. Human and non-human animals come into contact with each other in a variety of settings, and wherever there is contact there is the opportunity for interaction to take place. Interaction with companion animals are well known, but human–animal interaction (HAR (Hosey, 2008 also occurs in the context of farms (Hemsworth and Gonyou, 1997; Hemsworth, 2003, laboratories (Chang and Hart, 2002, zoos (Kreger and Mench, 1995 and even the wild (e.g. Cassini, 2001. This project proposes a permanent monitoring scheme to record animal-human interactions and animal-animal interactions in zoos. This will be accompanied by a survey of animal personality for welfare, husbandry, breeding programs and reintroduction purposes. The pilot project is currently based on direct monitoring of animal behaviour, use of time lapse cameras and animal personality questionnaires completed by experienced keepers. The goal of this project is to create a network between zoos to explore the aforementioned interactions to produce husbandry protocols and explore personality and behavioural traits in multiple species. We present provisional data regarding polar bear (Fasano Zoosafari, Italy, Sumatran tigers, Amur tigers and Asiatic lion (ZSL London and Whipsnade zoo interactions with humans and conspecifics. This data is collected across a broad range of environmental conditions and outlines the monitoring protocols developed to collect this data. The first year data show the great adaptability of these species to ex situ environments, low or absent negative impact of visitors’ presence and the relevance of individual personality in these interactions.

    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.

    An international research laboratory can be established on the Moon in the early years of the 21st Century. It can be built using the transportation system now envisioned by NASA, which includes a space station for Earth orbital logistics and orbital transfer vehicles for Earth-Moon transportation. A scientific laboratory on the Moon would permit extended surface and subsurface geological exploration; long-duration experiments defining the lunar environment and its modification by surface activity; new classes of observations in astronomy; space plasma and fundamental physics experiments; and lunar resource development. The discovery of a lunar source for propellants may reduce the cost of constructing large permanent facilities in space and enhance other space programs such as Mars exploration. 29 refs.

  3. Virtual Laboratories

    2006-01-01

    At the frontier of most areas in science, computer simulations play a central role. The traditional division of natural science into experimental and theoretical investigations is now completely outdated. Instead, theory, simulation, and experimentation form three equally essential aspects, each with its own unique flavor and challenges. Yet, education in computational science is still lagging far behind, and the number of text books in this area is minuscule compared to the many text books on theoretical and experimental science. As a result, many researchers still carry out simulations in a haphazard way, without properly setting up the computational equivalent of a well equipped laboratory. The art of creating such a virtual laboratory, while providing proper extensibility and documentation, is still in its infancy. A new approach is described here, Open Knowledge, as an extension of the notion of Open Source software. Besides open source code, manuals, and primers, an open knowledge project provides simul...

  4. Laboratory investigations

    International Nuclear Information System (INIS)

    Our task is to design mined-repository systems that will adequately secure high-level nuclear waste for at least 10,000 yr and that will be mechanically stable for 50 to 100-yr periods of retrievability during which mistakes could be corrected and a valuable source of energy could be reclaimed, should national policy on the reprocessing of spent fuel ever change. The only credible path for the escape of radionuclides from the repository to the biosphere is through ground-water, and in hard rock, bulk permeability is largely governed by natural and artificial fracture systems. Catastrophic failure of an excavation in hard rock is likely to occur at the weakest links - the discontinuities in the rock mass that is perturbed first by mining and then by radiogenic heating. The laboratory can contribute precise measurements of the pertinent thermomechanical, hydrological and chemical properties and improve our understanding of the fundamental processes through careful experiments under well controlled conditions that simulate the prototype environment. Thus laboratory investigations are necessary, but they are not sufficient, for conventional sample sizes are small relative to natural defects like joints - i.e., the rock mass is not a continuum - and test durations are short compared to those that predictive modeling must take into account. Laboratory investigators can contribute substantially more useful data if they are provided facilities for testing large specimens(say one cubic meter) and for creep testing of all candidate host rocks. Even so, extrapolations of laboratory data to the field in neither space nor time are valid without the firm theoretical foundations yet to be built. Meanwhile in-situ measurements of structure-sensitive physical properties and access to direct observations of rock-mass character will be absolutely necessary

    International audience In computer vision, the animation of objects has attracted a lot attention, specially the animations of 3D face models. The animation of face models requires in general to manually adapt each generic movement (open/close mouth) to each specific head geometry. In this work we propose a technique for the animation of any face model avoiding most of the manual intervention. In order to achieve this we assume that: (1) faces, despite obvious differences are quite similar...

    The general idea of this text is to reflect biopolitical constitution of the society and its implications related to the issues of animal welfare. Since animal in biopolitical formation is technically reduced to an object - commodity for contentment of the industry and of the people needs - critical public advisories are calling from moral, ethical and legal standpoint for attention to the fact that is necessary to protect animals from the unnecessary exploitation. It is obvious that animal p...

  12. 'Snow Queen' Animation

    Science.gov (United States)

    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. Spacecraft development is by Lockheed Martin Space Systems, Denver.

    2013-02-01

    Physiological and psychological effects of listening to music have been documented in humans. The changes in physiology, cognition and brain chemistry and morphology induced by music have been studied in animal models, providing evidence that music may affect animals similarly to humans. Information about the potential benefits of music to animals suggests that providing music may be used as a means of improving the welfare of laboratory animals, such as through environmental enrichment, stress relief and behavioral modification. The authors review the current research on music's effect on animals' physiology and behavior and discuss its potential for improving animal welfare. They conclude that the benefits of providing music to laboratory animals depend on the species and the type of music.

    Science.gov (United States)

    Epstein, Yoram; Leshem, Micah

    2002-04-01

    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.

  18. Future improvements and implementation of animal care practices within the animal testing regulatory environment.

    Science.gov (United States)

    Guittin, Pierre; Decelle, Thierry

    2002-01-01

    Animal welfare is an increasingly important concern when considering biomedical experimentation. Many of the emerging regulations and guidelines specifically address animal welfare in laboratory animal care and use. The current revision of the appendix of the European Convention, ETS123 (Council of Europe), updates and improves on the current animal care standardization in Europe. New guidelines from the Organisation for Economic Co-operation and Development and the European Federation of Pharmaceutical Industries Association focus specifically on safety testing. These guidelines will affect the way toxicity studies are conducted and therefore the global drug development process. With the 3Rs principles taken into account, consideration regarding animal welfare will demand changes in animal care practices in regulatory safety testing. The most significant future improvements in animal care and use practices are likely to be environmental enrichment, management of animal pain and distress, and improved application of the humane endpoints. Our challenge is to implement respective guidelines based on scientific data and animal welfare, through a complex interplay of regulatory objective and public opinion. The current goal is to work toward solutions that continue to provide relevant animal models for risk assessment in drug development and that are science based. In this way, future improvements in animal care and use practices can be founded on facts, scientific results, and analysis. Some of these improvements become common practice in some countries. International harmonization can facilitate the development and practical application of "best scientific practices" by the consensus development process that harmonization requires. Since the implementation of good laboratory practices (GLP) standards in safety testing, these new regulations and recommendations represent a new way forward for animal safety studies.

    Espinosa-Cervantes, Román; Córdova-Izquierdo, Alejandro

    2013-01-01

    The ability to preselect or predetermine the sex of offspring prior to conception is a highly desired technological tool for assisted female breeding programs specifically for milk production, and in males, for meat production and increasing livestock numbers. The current technology is based on the well-known differences in X- and Y-sperm in the amount of DNA. The technology uses modified flow cytometric instrumentation for sorting X- and Y-bearing sperm. The method can be validated on the basis of live births, laboratory reanalysis of sorted sperm for DNA content, and embryo biopsy for sex determination. Currently, the sex of animals has been predetermined with 90 % accuracy by sexing spermatozoa. In the bovine breeding industry, flow cytometric sperm sexing has not fulfilled its original promise. Sexed sperm doses are too expensive for widespread application while the fertility of sexed sperm doses is lower than unsexed ones. Essentially all bovine sexed semen is frozen and then applied through artificial insemination (AI) or in vitro fertilization. There is still a need in the animal breeding industry to develop a technique for sperm sexing that provides sufficient spermatozoa for AI doses, does not compromise sperm fertility, and is widely applicable to a range of species. In this review, we will summarize the current state-of-the-art in sex preselection in domestic animals and some wildlife species using flow cytometric sperm-sorting of X from Y sperm based on DNA differences.

    Neurocysticercosis is a public health problem in many developing countries and is the most frequent parasitic disease of the brain. The human tapeworm carrier is the main risk factor for acquiring neurocysticercosis. Since the parasite lodges only in the human intestine, experimental models of Taenia solium taeniosis have been explored. Macaques, pigs, dogs, cats and rabbits are unsuccessful hosts even in immunodepressed status. By contrast, rodents are adequate hosts since tapeworms with mature, pregravid and, in some cases, gravid proglottids develop after infection. In this review, information that has been generated with experimental models of taeniosis due to T. solium is discussed. Initially, the use of the model for immunodiagnosis of human taeniosis and evaluation of intervention measures is summarized. Next, descriptions of tapeworms and comparison of hamsters, gerbils and other mammals as experimental models are discussed, as well as data on the humoral immune response, the inflammatory reaction and the production of cytokines associated to Th1 and Th2 responses in the intestinal mucosa. Finally, evaluation of protection induced against the development of tapeworms by recombinant T. solium calreticulin in hamsters is summarized and compared to other studies.

    Obesity and obesity-related metabolic diseases represent a growing socioeconomic problem throughout the world.Great emphasis has been put on establishing treatments for this condition,including pharmacological intervention.However,there are many obstacles and pitfalls in the development process from pre-clinical research to the pharmacy counter,and there is no certainty that what has been observed pre-clinically will translate into an improvement in human health.Hence,it is important to test potential new drugs in a valid translational model early in their development.In the current mini-review,a number of monogenetic and polygenic models of obesity will be discussed in view of their translational character.

    Brown, N K; Harvey, D J

    1990-01-01

    Metabolism of cannabichromene (CBC) was studied in hepatic microsomal incubates from mouse, rat, rabbit, guinea pig, cat, hamster, and gerbil. Metabolites were extracted with ethyl acetate, concentrated by chromatography on Sephadex LH-20, and identified by GC/MS as trimethylsilyl derivatives of both the metabolites themselves and their hydrogenated analogues. Thirteen metabolites were identified. The major metabolites were monohydroxy compounds with hydroxylation at all positions of the pentyl and methylpentenyl chains. An epoxide and its derived dihydrodiol were formed from the double bond in the methylpentenyl chains. Several unidentified decomposition products were found in the extracts from mouse, gerbil, and cat; these appeared to have been produced by the opening of the dihydropyran ring. Metabolism varied considerably between the species, although the trans-hydroxy metabolite 5'-hydroxy-CBC was the major metabolite in most cases. Metabolites hydroxylated in the pentyl chain were more abundant in mouse, rabbit, and cat; the hamster, gerbil, and cat produced the most epoxide-derived material. PMID:1981514

    The number of animals used in research has increased with the advancement of research and development in medical technology. Every year, millions of experimental animals are used all over the world. The pain, distress and death experienced by the animals during scientific experiments have been a debating issue for a long time. Besides the major concern of ethics, there are few more disadvantages of animal experimentation like requirement of skilled manpower, time consuming protocols and high cost. Various alternatives to animal testing were proposed to overcome the drawbacks associated with animal experiments and avoid the unethical procedures. A strategy of 3 Rs (i.e. reduction, refinement and replacement) is being applied for laboratory use of animals. Different methods and alternative organisms are applied to implement this strategy. These methods provide an alternative means for the drug and chemical testing, up to some levels. A brief account of these alternatives and advantages associated is discussed in this review with examples. An integrated application of these approaches would give an insight into minimum use of animals in scientific experiments. PMID:26106269

    2010-05-01

    Full Text Available Online hardware-based educational laboratories are increasingly being deployed in traditional on-campus as well as Web-based distance-learning courses around the world. An online laboratory generally will consist of several hardware-based remote experiments. However, one particular experiment can be performed at a time by an individual student or a group of students which require a careful scheduling of the experiments. For the proper implementation of an online laboratory an efficient laboratory management system (LMS is thus essential. Also for an online laboratory, the students need to fully understand the experimental system setup and feel comfortable as in an actual laboratory environment which, however, can be effectively done by adding suitable videos and animations etc. Besides, the students should be able to run the remote experiments, extract, save and analyze the data and submit laboratory reports online. The front end of the laboratory management system should be made browser-based so that one can use the laboratory facility from anywhere. Also, for the teachers, the laboratory management system should include an online evaluation for the quiz/viva-voce, checking experimental data, grading of submitted laboratory reports and feedback for the students. In this paper, we describe the design and prototype implementation of an online laboratory management system (for use with shared hardware-based remote laboratory resources which may be employed for running internet-based online laboratory courses for geographically dispersed Institutions.

    A rodent biosecurity program that includes periodic evaluation of procedures used in an institution's vivarium can be used to ensure that best practices are in place to prevent a microbial pathogen outbreak. As a result of an ongoing comprehensive biosecurity review within their North American and European production facilities, the authors developed a novel biosecurity auditing process and worksheet that could be useful in other animal care and use operations. The authors encourage other institutions to consider initiating similar audits of their biosecurity programs to protect the health of their laboratory animals. PMID:24150170

  11. Animals as disgust elicitors

    DEFF Research Database (Denmark)

    Kasperbauer, Tyler Joshua

    2015-01-01

    This paper attempts to explain how and why nonhuman animals elicit disgust in human beings. I argue that animals elicit disgust in two ways. One is by triggering disease–protection mechanisms, and the other is by eliciting mortality salience, or thoughts of death. I discuss how these two types...... of disgust operate and defend their conceptual and theoretical coherence against common objections. I also outline an explanatory challenge for disgust researchers. Both types of disgust indicate that a wide variety of animals produce aversive and avoidant reactions in human beings. This seems somewhat odd......, given the prominence of animals in human lives. The challenge, then, is explaining how humans cope with the presence of animals. I propose, as a hypothesis for further exploration, that we cope with animals, and our disgust responses to them, by attributing mental states that mark them as inferior...

  12. Small Animal Retinal Imaging

    Science.gov (United States)

    Choi, WooJhon; Drexler, Wolfgang; Fujimoto, James G.

    Developing and validating new techniques and methods for small animal imaging is an important research area because there are many small animal models of retinal diseases such as diabetic retinopathy, age-related macular degeneration, and glaucoma [1-6]. Because the retina is a multilayered structure with distinct abnormalities occurring in different intraretinal layers at different stages of disease progression, there is a need for imaging techniques that enable visualization of these layers individually at different time points. Although postmortem histology and ultrastructural analysis can be performed for investigating microscopic changes in the retina in small animal models, this requires sacrificing animals, which makes repeated assessment of the same animal at different time points impossible and increases the number of animals required. Furthermore, some retinal processes such as neurovascular coupling cannot be fully characterized postmortem.

    Science.gov (United States)

    Rushen, J; Butterworth, A; Swanson, J C

    2011-04-01

    Public and consumer pressure for assurances that farm animals are raised humanely has led to a range of private and public animal welfare standards, and for methods to assess compliance with these standards. The standards usually claim to be science based, but even though researchers have developed measures of animal welfare and have tested the effects of housing and management variables on welfare within controlled laboratory settings, there are challenges in extending this research to develop on-site animal welfare standards. The standards need to be validated against a definition of welfare that has broad support and which is amenable to scientific investigation. Ensuring that such standards acknowledge scientific uncertainty is also challenging, and balanced input from all scientific disciplines dealing with animal welfare is needed. Agencies providing animal welfare audit services need to integrate these scientific standards and legal requirements into successful programs that effectively measure and objectively report compliance. On-farm assessment of animal welfare requires a combination of animal-based measures to assess the actual state of welfare and resource-based measures to identify risk factors. We illustrate this by referring to a method of assessing welfare in broiler flocks. Compliance with animal welfare standards requires buy-in from all stakeholders, and this will be best achieved by a process of inclusion in the development of pragmatic assessment methods and the development of audit programs verifying the conditions and continuous improvement of farm animal welfare.

    The development of the first vaccines for use in animals, by Louis Pasteur at the end of the 19th Century, was an initial step in applying biotechnology to animal health. However, it is only much more recently that decisive progress has been made in finding applications for biotechnology, in both detecting and preventing infectious and parasitic diseases. This progress has shown the way to developing a range of procedures, the application of which will benefit the health of domestic and wild animals, enhance the well-being of companion animals, develop the performance of sporting animals and improve the productivity of farm animals, while also serving to protect human health. Such progress results from the increasingly rapid application of knowledge gained in the material and life sciences, all of which contribute to the multidisciplinary nature of biotechnology. Similarly, reagents and diagnostic techniques have been made more specific, sensitive, reproducible, rapid and robust by updating them through recent discoveries in immunology, biochemistry and molecular biology (monoclonal antibodies, nucleic probes, deoxyribonucleic acid amplification and many more). The development of new vaccines which combine efficacy, duration of protection, innocuity, stability, multivalence and ease of use (subunit vaccines, recombinant vaccines, synthetic vaccines and anti-idiotype vaccines) has resulted from recent progress in immunology, immunochemistry, molecular biology and biochemistry. Finally, the availability of new anti-infective, anti-parasitic agents and immunomodulatory therapeutic agents (capable of stimulating the specific and non-specific defence mechanisms of the body) demonstrates that biotechnology is continuing to find new applications in the field of animal health. New diagnostic techniques, vaccines and therapeutic substances are the most immediate applications of knowledge which may, in the future, extend to the development of transgenic animals of revised

  20. Indian draught animals power

    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.

  8. Interaction between animal personality and animal cognition

    Directory of Open Access Journals (Sweden)

    Claudio CARERE, Charles LOCURTO

    2011-08-01

    Full Text Available The study of animal personality has attracted considerable attention, as it has revealed a number of similarities in personality between humans and several nonhuman species. At the same time the adaptive value and evolutionary maintenance of different personalities are the subject of debate. Since Pavlov’s work on dogs, students of comparative cognition have been aware that animals display vast individual differences on cognitive tasks, and that these differences may not be entirely accounted for differences in cognitive abilities. Here, we argue that personality is an important source of variation that may affect cognitive performance and we hypothesise mutual influences between personality and cognition across an individual’s lifespan. In particular, we suggest that: 1 personality profiles may be markers of different cognitive styles; 2 success or failure in cognitive tasks could affect different personalities differently; 3 ontogenetic changes of personality profiles could be reflected in changes in cognitive performance. The study of such interplay has implications in animal welfare as well as in neuroscience and in translational medicine [Current Zoology 57 (4: 491–498, 2011].

  9. 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.

  13. Animal Health in Albania

    International Nuclear Information System (INIS)

    The animal health service policy in Albania represents an integral component of overall governmental, social and economic policy in the field of agricultural and rural development, public health, food processing and import/export of animal products. In order to obtain the necessary political, economic and public support, the animal health service attempts to contribute effectively to the overall development of the country which aims at improving the standards of living of its inhabitants. Practical means of contributing to national development include reducing food loses due to animal morbidity and mortality, increasing the productivity of the livestock population, protecting human health against zoonotic diseases and ensuring humane treatment of animals. An animal health strategy contributes to the creation of conditions necessary for uninterrupted animal disease surveillance and control in the country. The main animal health problem in Albania is brucellosis in ruminants, caused by B. melitensis. This infection currently affects the entire country, reaching a prevalence of 10% in several districts. The latest and most severe outbreaks of classical swine fever were identified on 1996 when 5 515 animals were infected and 3 683 animals died. The circulation of bluetongue virus (BTV) was detected for the first time in Albania in 2002 with a seroprevalence of 15%. The evidence of BTV circulation in Albania and the absence of the main vector C. imicola suggest that other Culicoides species could be implicated in virus transmission. H5N1 avian influenza in Albania was confirmed in March 2006 in backyard flocks in the villages of Cuke and Peze-Helmes. In both villages there were no human cases. Rabies was of concern in Albania from 1928 until 1976. The disease re-emerged in March 2001 in the village of Morine in Kukes district affecting a domestic dog and three persons were bitten. Other cases have been reported in northern Albania. (author)

  14. Parasite survey in mouse and rat colonies of Brazilian laboratory animal houses kept under differents sanitary barrier conditions Estudo de parasitos em colônias de ratos e de camundongos em biotérios brasileiros mantidos sob diferentes condições de barreiras sanitárias

    Full Text Available A parasitological study was undertaken to determine the health status of 15 mouse and 10 rat colonies bred in 18 Brazilian laboratory animal houses maintained under different sanitary barrier conditions which supply animals for teaching, research purposes and manufacture of biological products for medical or veterinary use. Parasitological methods were used for diagnosis of mites, lices, helminthes and protozoan parasites. A questionnaire was answered by institutions with the intention to obtain information about the existence of barriers against infections and of regular sanitary monitoring program of their colonies. The questionnaire data show that the majority of the animal houses investigated do not possess an efficient sanitary barrier system able to keep animals under controlled health sanitary conditions. Ecto and endoparasite infections are widespread in the colonies and multiple infections were common in animals from most facilities investigated. The prevalences of parasites detected among the mouse and rat colonies of the laboratory animal houses investigated were: Myocoptes musculinus (46.6%, Myobia musculi (26.6%, Radfordia ensifera (13.3%, Syphacia obvelata (86.6%, Aspiculuris tetraptera (60.0%, Hymenolepis nana (53.3%, Spironucleus muris (80.0%, Tritrichomonas muris (80.0%, Giardia muris (66.0%, Entamoeba muris (20.0%, Eimeria sp.

    Behrensdorf-Nicol, H; Krämer, B

    2014-10-01

    In order to ensure the quality of biomedical products, an experimental test for every single manufactured batch is required for many products. Especially in vaccine testing, animal experiments are traditionally used for this purpose. For example, efficacy is often determined via challenge experiments in laboratory animals. Safety tests of vaccine batches are also mostly performed using laboratory animals. However, many animal experiments have clear inherent disadvantages (low accuracy, questionable transferability to humans, unclear significance). Furthermore, for ethical reasons and animal welfare aspects animal experiments are also seen very critical by the public. Therefore, there is a strong trend towards replacing animal experiments with methods in which no animals are used ("replacement"). If a replacement is not possible, the required animal experiments should be improved in order to minimize the number of animals necessary ("reduction") and to reduce pain and suffering caused by the experiment to a minimum ("refinement"). This "3R concept" is meanwhile firmly established in legislature. In recent years many mandatory animal experiments have been replaced by alternative in vitro methods or improved according to the 3R principles; numerous alternative methods are currently under development. Nevertheless, the process from the development of a new method to its legal implementation takes a long time. Therefore, supplementary regulatory measures to facilitate validation and acceptance of new alternative methods could contribute to a faster and more consequent implementation of the 3R concept in the testing of biomedical products.

    Shankar B. P.

    2009-06-01

    Full Text Available Laboratory work should be carried out with a minimum of risk to the health of the staff working in laboratory. This requires careful consideration of the risks involved in a particular procedure,followed by appropriate measures to minimise the risk of human disease. This concerned exclusively with risks from infectious agents, but physical and chemical injuries in microbiology laboratories must also be prevented. Risks from infection are reduced by good laboratory techniques and secured facilities which aid in the containment of pathogens. It is important to understand that containment of pathogens can be used for preventing disease in humans and animals. Often the same methods of containment are used for both preventing laboratory-acquired infection in humans and for preventing escape of pathogens that could cause an outbreak of animal disease. Although the methods, techniques and facilities required may be the same, the list of pathogens and categorization into levels of risk will differ depending on whether it is human or animal disease control that is the primary objective. Existing national and international reference laboratories have considerable experience in the operation of safe working practices and provision of appropriate facilities. When new laboratories are being established, it would be prudent to seek advice from the competent authorities at established institutes and it is important to comply with legislative requirements.

    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.

    John Maynard Keynes argued that when the conditions for rational action are not present, people are driven by "animal spirits." This article briefly considers Keynes' argument, and the history of the term.

  13. [Alternatives to animal testing].

    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. PMID:20669543

    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.

    Computer animation of outdoor scenes is enhanced by realistic clouds. I will discuss several different modeling and rendering schemes for clouds, and show how they evolved in my animation work. These include transparency-textured clouds on a 2-D plane, smooth shaded or textured 3-D clouds surfaces, and 3-D volume rendering. For the volume rendering, I will present various illumination schemes, including the density emitter, single scattering, and multiple scattering models.

    It is an obvious obligation for investigators to consume millions of experimental animals every year to obtain scientific data. Because most of these experiments involve painful and distressing procedures, to obey the so-called 3Rs, reduction, refinement and replacement, is a prerequisite for those who would apply to ethics committees for a given research proposal. Of the 3Rs, refinement could be defined as “decrease in the incidence of severity of inhumane procedures applied to those animals...

    Developing reliable, predictive animal models for complex psychiatric disorders, such as schizophrenia, is essential to increase our understanding of the neurobiological basis of the disorder and for the development of novel drugs with improved therapeutic efficacy. All available animal models of schizophrenia fit into four different induction categories: developmental, drug-induced, lesion or genetic manipulation, and the best characterized examples of each type are reviewed herein. Most rod...

    Nowadays it is common to talk about metaphor. In fact, metaphor is a kind of comparison. Because of comparison and association,familiar objects become strange and glamorous. Animal metaphors can involve either nominal form or verb forms. A person's crying may be called barking. A woman may be called a cat, or a goose, etc. Animal metaphor is connected tightly with our life and helps language development. We can utilize them to make our life and languages more colorful.
