    Empathy and affective appraisals for conspecifics are among the hallmarks of social interaction. Using functional MRI, we hypothesized that vegetarians and vegans, who made their feeding choice for ethical reasons, might show brain responses to conditions of suffering involving humans or animals different from omnivores. We recruited 20 omnivore subjects, 19 vegetarians, and 21 vegans. The groups were matched for sex and age. Brain activation was investigated using fMRI and an event-related d...

    Empathy and affective appraisals for conspecifics are among the hallmarks of social interaction. Using functional MRI, we hypothesized that vegetarians and vegans, who made their feeding choice for ethical reasons, might show brain responses to conditions of suffering involving humans or animals different from omnivores. We recruited 20 omnivore subjects, 19 vegetarians, and 21 vegans. The groups were matched for sex and age. Brain activation was investigated using fMRI and an event-related design during observation of negative affective pictures of human beings and animals (showing mutilations, murdered people, human/animal threat, tortures, wounds, etc.). Participants saw negative-valence scenes related to humans and animals, alternating with natural landscapes. During human negative valence scenes, compared with omnivores, vegetarians and vegans had an increased recruitment of the anterior cingulate cortex (ACC) and inferior frontal gyrus (IFG). More critically, during animal negative valence scenes, they had decreased amygdala activation and increased activation of the lingual gyri, the left cuneus, the posterior cingulate cortex and several areas mainly located in the frontal lobes, including the ACC, the IFG and the middle frontal gyrus. Nonetheless, also substantial differences between vegetarians and vegans have been found responding to negative scenes. Vegetarians showed a selective recruitment of the right inferior parietal lobule during human negative scenes, and a prevailing activation of the ACC during animal negative scenes. Conversely, during animal negative scenes an increased activation of the inferior prefrontal cortex was observed in vegans. These results suggest that empathy toward non conspecifics has different neural representation among individuals with different feeding habits, perhaps reflecting different motivational factors and beliefs.

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

    The human ability to perceive and understand others' suffering is critical to reinforcing and maintaining our social bonds. What is not clear, however, is the extent to which this generalizes to nonhuman entities. Anecdotal evidence indicates that people may engage in empathy-like processes when observing suffering nonhuman entities, but psychological research suggests that we more readily empathize with those to whom we are closer and more similar. In this research, we examined neural responses in participants while they were presented with pictures of human versus dog suffering. We found that viewing human and animal suffering led to large overlapping regions of activation previously implicated in empathic responding to suffering, including the anterior cingulate gyrus and anterior insula. Direct comparisons of viewing human and animal suffering also revealed differences such that human suffering yielded significantly greater medial prefrontal activation, consistent with high-level theory of mind, whereas animal suffering yielded significantly greater parietal and inferior frontal activation, consistent with more semantic evaluation and perceptual simulation.

    Refinement of procedures and models that use living animals makes a real difference to scientific validity, data quality and animal welfare. Refinements can be small and iterative and are frequently introduced without a premeditated plan, as part of general procedure development. Whilst this is encouraging, integrating refinement into experimental design is critical to reduction of suffering. A well put together welfare assessment protocol, established through a detailed analysis of each step of the model or procedure, is a very important tool for implementing refinements. This paper will give practical steps for identification of suffering in animals used for scientific purposes and provide examples of refinements to reduce suffering and improve welfare.

    Full Text Available Chicken pox (CP is a generalized primary infection that occurs the first time an individual contacts the virus. The etiology of CP is a VZV virus, and the replication of virus allowing recovery in two to three weeks. During the process, the VZV may progress along sensory nerves to the sensory ganglia, where it can reside in a latent, undetectable form; and can be reactivated at any time. Recurrent aphthous stomatitis (RAS is a recurrent ulcer in the mouth, painful, disturbing the mouth's function and esthetic when occurs in the lips. One of the etiology of RAS is the reactivation of the latent virus in the mouth. The aim of this study was to know the contribution of the latent virus in the ganglia, intervered with the differences of the healing duration of RAS in female students, between the CP sufferer and non CP sufferer. By cross-sectionally, clinical examination, after filling the questioner that included informed consent, 307 students of The St. Yusup Senior High School, Karangpilang Surabaya, were examined. In the 3rd class, there were only 6 female students that suffered RAS had CP history, while 11, student did not. Levene's test for equality of variances was done, and p: 0.698, while 2-tail sign: 0.512. According to this statistical analysis, there was no significant difference between the two groups examined. It was suggested that the female students of RAS' sufferer should maintain their balanced food intake, so the ulcer of RAS would heal quickly.

    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.

    Full Text Available Introduction: Schizophrenia is devastating neuropsychiatric disorder that has no clearly identified etiology. The subtypes of schizophrenia are distinguished by the prevalent symptomatology. The aim of this study was to determine gender related differences in demographic and clinical manifestations in patients suffering from various subtypes of schizophrenia.Methods: A longitudinal, prospective,original,clinical investigation first in our local area, with application of Structured Clinical Interview for DSM IV Axis I Disorders (SCID I was used in this work. The study included 121 patients during five years period. Patients were recruited as consecutive admissions to the Psychiatric clinic, from all parts of Bosnia and Herzegovina, mostly Sarajevo region.Results: The study was conducted on a group of schizophrenic patients which consisted of 52.1% male and 47.9% female patients. Average duration of the episode was about a month. Majority of patients (male were in the group of disorganized (hebephrenic schizophrenia. The duration of current psychotic episode was similar in all three groups regarding subtypes of schizophrenia. Psychotic episodes appear equally in both gender (higher in disorganized group with a statistically significant difference between all groups (p<0.001.Conclusions: Male group patients showed tendency to be younger than women. Most of the schizophrenic individuals start to suffer from this disease between age of 20 and 39 years. Male group patients suffered mostly of disorganized (hebephrenic type of schizophrenia. Duration of psychotic episode was proportionally the same in both groups while in male group the highest number of episodes was found in group of disorganized schizophrenia.

  19. Attention "blinks" differently for plants and animals.

    2014-01-01

    Plants, to many, are simply not as interesting as animals. Students typically prefer to study animals rather than plants and recall plants more poorly, and plants are underrepresented in the classroom. The observed paucity of interest for plants has been described as plant blindness, a term that is meant to encapsulate both the tendency to neglect plants in the environment and the lack of appreciation for plants' functional roles. While the term plant blindness suggests a perceptual or attentional component to plant neglect, few studies have examined whether there are real differences in how plants and animals are perceived. Here, we use an established paradigm in visual cognition, the "attentional blink," to compare the extent to which images of plants and animals capture attentional resources. We find that participants are better able to detect animals than plants in rapid image sequences and that visual attention has a different refractory period when a plant has been detected. These results suggest there are fundamental differences in how the visual system processes plants that may contribute to plant blindness. We discuss how perceptual and physiological constraints on visual processing may suggest useful strategies for characterizing and overcoming zoocentrism. PMID:25185227

    From ancient times the Bible, theology and philosophy have dealt with the problem of human suffering. The German concept of "Leidensdruck" means a "pressure" caused by suffering, which prompts the patient to see a doctor. It is worthwhile to deal with suffering from a holistic point of view as well, which can be described as somatic, mental, social and spiritual forms of distress. As all kinds of human suffering are summed up (reflected by) in the psyche, they are mostly followed by psychopathological alterations (i.e. depression); therefore, it is another reason why it is useful to deal with the problem. If suffering is considered as multi-causal condition, personality elements have to be excluded as they can decrease or increase pain. In addition to aetiological factor, the role of coping and defence mechanisms has to be considered as well. The process of suffering - mainly with chronic diseases - goes along with the increase of pain (e.g. with malignant tumours), or luckily with discontinuation of pain by therapy. In a doctor-patient relationship dealing with suffering, a holistic attitude is needed in order to understand the patient better. It may contribute to what Michael Bálint proposed to doctors who use psychotherapy in their practice: the so-called autogenous picture of the disorder developed by the patient has to be reconciled with the doctor's iatrogenous one. The clearer the perspective, the view of the disease, the better patient compliance can be expected. PMID:18421095

    2015-01-01

    Stockmanship is a term used to describe the management of animals with a good stockperson someone who does this in a in a safe, effective, and low-stress manner for both the stock-keeper and animals involved. Although impacts of unfamiliar zoo visitors on animal behaviour have been extensively studied, the impact of stockmanship i.e familiar zoo keepers is a new area of research; which could reveal significant ramifications for zoo animal behaviour and welfare. It is likely that different relationships are formed dependant on the unique keeper-animal dyad (human-animal interaction, HAI). The aims of this study were to (1) investigate if unique keeper-animal dyads were formed in zoos, (2) determine whether keepers differed in their interactions towards animals regarding their attitude, animal knowledge and experience and (3) explore what factors affect keeper-animal dyads and ultimately influence animal behaviour and welfare. Eight black rhinoceros (Diceros bicornis), eleven Chapman's zebra (Equus burchellii), and twelve Sulawesi crested black macaques (Macaca nigra) were studied in 6 zoos across the UK and USA. Subtle cues and commands directed by keepers towards animals were identified. The animals latency to respond and the respective behavioural response (cue-response) was recorded per keeper-animal dyad (n = 93). A questionnaire was constructed following a five-point Likert Scale design to record keeper demographic information and assess the job satisfaction of keepers, their attitude towards the animals and their perceived relationship with them. There was a significant difference in the animals' latency to appropriately respond after cues and commands from different keepers, indicating unique keeper-animal dyads were formed. Stockmanship style was also different between keepers; two main components contributed equally towards this: "attitude towards the animals" and "knowledge and experience of the animals". In this novel study, data demonstrated unique dyads

    2014-01-01

    It is well-known that anime art has been existed as far back as the 1920s. While along with the continued development of china’s economy since the reform and opening up, anime art went into its rapid development stage. As we all know, aesthetic feeling differs from one person to another because of the differences of age, gender, geography, etc. Therefore, artistic value can only be demonstrated in the anime art when anime art can satisfy all different aesthetic feelings. The present thesis gives an analysis into the anime art creation from the perspective of aesthetic consensus and aesthetic difference, which can stimulate the sustainable development of anime art and inspire anime creators to become better and better in the field of anime and create more better works.

    Animal models have historically played a critical role in the exploration and characterization of disease pathophysiology and target identification and in the evaluation of novel therapeutic agents and treatments in vivo. Diabetes mellitus disease, commonly known as diabetes, is a group of metabolic disorders characterized by high blood glucose levels for a prolonged time. To avoid late complications of diabetes and related costs, primary prevention and early treatment are therefore necessary. Due to its chronic symptoms, new treatment strategies need to be developed, because of the limited effectiveness of the current therapies. We overviewed the pathophysiological features of diabetes in relation to its complications in type 1 and type 2 mice along with rat models, including Zucker Diabetic Fatty (ZDF) rats, BB rats, LEW 1AR1/-iddm rats, Goto-Kakizaki rats, chemically induced diabetic models, and Nonobese Diabetic mouse, and Akita mice model. The advantages and disadvantages that these models comprise were also addressed in this review. This paper briefly reviews the wide pathophysiological and molecular mechanisms associated with type 1 and type 2 diabetes, particularly focusing on the challenges associated with the evaluation and predictive validation of these models as ideal animal models for preclinical assessments and discovering new drugs and therapeutic agents for translational application in humans.

    Connotative meanings of animals in Chinese and in English are usually different. These differences are the result of various cultural backgrounds, especially the cognition models, in shaping and developing Chinese and English. This paper illustrates the different connotative meanings of animals on the basis of classifying animals into two general categories: the Chinese culturally-loaded ones and common ones both in Chinese and in English.

    Psychiatric disorders are characterized by sex differences in their prevalence, symptomatology and treatment response. Animal models have been widely employed for the investigation of the neurobiology of such disorders and the discovery of new treatments. However, mostly male animals have been used in preclinical pharmacological studies. In this review, we highlight the need for the inclusion of both male and female animals in experimental studies aiming at gender-oriented prevention, diagnos...

  15. Long-term evacuation after the nuclear accident in Fukushima. Different daily living under low-dose radioactive suffering

    International Nuclear Information System (INIS)

    One year has passed since the Great East Japan Earthquake and the Fukushima No. 1 nuclear power plant accident. Even currently, more than 150,000 evacuees in Fukushima Prefecture are forced to leave their home and to move throughout Japan. Because of the limited space of temporary housing and the weakening of personal ties in local communities, many families need to move and have separate lives. As a consequence, Fukushima has a serious shortage of caregivers for the elderly. There have been more than 1,300 disaster-related deaths due to shock and stress after long-distance drifts from town to town. Most of the victims were the elderly, who collapsed, caught pneumonia, suffered stroke and heart attack. Concerns about the safety of low-dose radiation exposure deprived the elderly of important contact with playing outside with their grandchildren in Fukushima. Fear of invisible radioactive contamination inactivated outdoor activities such as farming, dairy, fishing, gardening, hiking and wild-vegetable/mushroom hunting, although most of these activities have been traditionally supported by the wisdom of the elderly. Several recent questionnaire investigations revealed that older evacuees wish to go home even if the environment has significant contamination. In contrast, more than half of younger generation with small children have a different attitude. Nuclear accident brought serious social pains although it did not acutely hurt our bodies. (author)

  18. Integration of animal behaviors under stresses with different time courses

    2014-01-01

    We used animal models of“forced swim stress”and“chronic unpredictable stress”, and tried to reveal whether a passive coping style of high lfotation behavior in forced swim stress predicts an-hedonia behavior after chronic unpredictable stress, and whether the dopamine system regulates lfoating and anhedonia behaviors. Our results conifrmed that depression-prone rats use“lfoating behavior”as a coping strategy in forced swim stress and more readily suffer from anhedonia during chronic unpredictable stress. Intraperitoneal injection or nucleus accumbens microin-jection of the dopamine 2/3 receptor subtype agonist ropinirole reduced lfoating behaviors in depression-prone animals, but increased sucrose preference in rats showing anhedonia. These data indicate that lfoating behavior is a defensive mode that is preferred by susceptible individ-uals under conditions of acute stress. Simultaneously, these animals more readily experienced anhedonia under long-term stress;that is, they were more readily affected by depression. Our results suggest that dopamine 2/3 receptor subtypes in the nucleus accumbens play an important role in lfoating behaviors and anhedonia.

  19. Do plants and animals differ in phenotypic plasticity?

    Indian Academy of Sciences (India)

    Renee M Borges

    2005-02-01

    This paper compares the flexibility in the nexus between phenotype and genotype in plants and animals. These taxa although considered to be fundamentally different are found to be surprisingly similar in the mechanisms used to achieve plasticity. Although non-cognitive behaviour occurs in plants, its range is limited, while morphological and developmental plasticity also occur to a considerable extent in animals. Yet both plants and animals are subject to unique constraints and thus need to find unique solutions to functional problems. A true comparison between the plant and animal phenotype would be a comparison between plants and sessile photo-synthesizing colonial invertebrates. Such comparisons are lacking. However, they would provide important insights into the adaptive significance of plasticity in these groups. It is also suggested that a comparison of inflexible traits in these groups would provide an understanding of the constraints, as well as the costs and benefits, of a plastic versus non-plastic phenotype in plants and animals.

  20. Animals

    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)

  1. Sex Differences in Animal Models: Focus on Addiction.

    Science.gov (United States)

    Becker, Jill B; Koob, George F

    2016-04-01

    The purpose of this review is to discuss ways to think about and study sex differences in preclinical animal models. We use the framework of addiction, in which animal models have excellent face and construct validity, to illustrate the importance of considering sex differences. There are four types of sex differences: qualitative, quantitative, population, and mechanistic. A better understanding of the ways males and females can differ will help scientists design experiments to characterize better the presence or absence of sex differences in new phenomena that they are investigating. We have outlined major quantitative, population, and mechanistic sex differences in the addiction domain using a heuristic framework of the three established stages of the addiction cycle: binge/intoxication, withdrawal/negative affect, and preoccupation/anticipation. Female rats, in general, acquire the self-administration of drugs and alcohol more rapidly, escalate their drug taking with extended access more rapidly, show more motivational withdrawal, and (where tested in animal models of "craving") show greater reinstatement. The one exception is that female rats show less motivational withdrawal to alcohol. The bases for these quantitative sex differences appear to be both organizational, in that estradiol-treated neonatal animals show the male phenotype, and activational, in that the female phenotype depends on the effects of gonadal hormones. In animals, differences within the estrous cycle can be observed but are relatively minor. Such hormonal effects seem to be most prevalent during the acquisition of drug taking and less influential once compulsive drug taking is established and are linked largely to progesterone and estradiol. This review emphasizes not only significant differences in the phenotypes of females and males in the domain of addiction but emphasizes the paucity of data to date in our understanding of those differences.

    The main goal of the current study was to investigate sex differences in the relationship between the level of trauma symptoms appearing in posttraumatic stress disorder (PTSD) and intensity of pain in a sample of 300 Polish patients suffering from chronic pain, specifically rheumatoid arthritis and lower back pain. We also focused on participants' body image with body esteem as a mediator. To assess the intensity of pain among participants, we used the Numerical Rating Scale. The level of trauma symptoms was assessed with the PTSD Factorial Version Inventory. To measure body image among participants, we used the Body Esteem Scale. The results of our study suggest that trauma symptoms and body image dimensions were significant predictors of pain intensity among men suffering from chronic pain. Moreover, trauma symptoms and age were significant predictors of pain intensity among women suffering from chronic pain. Finally, we demonstrated that sex differentiates the reaction to chronic pain.

  4. Gender Differences in Animal Models of Posttraumatic Stress Disorder

    2011-01-01

    Full Text Available Epidemiological studies report higher prevalence rates of stress-related disorders such as acute stress disorder and post-traumatic stress disorder (PTSD in women than in men following exposure to trauma. It is still not clear whether this greater prevalence in woman reflects a greater vulnerability to stress-related psychopathology. A number of individual and trauma-related characteristics have been hypothesized to contribute to these gender differences in physiological and psychological responses to trauma, differences in appraisal, interpretation or experience of threat, coping style or social support. In this context, the use of an animal model for PTSD to analyze some of these gender-related differences may be of particular utility. Animal models of PTSD offer the opportunity to distinguish between biological and socio-cultural factors, which so often enter the discussion about gender differences in PTSD prevalence.

    2014-06-01

    We report bipolar resistive switching phenomena observed in different types of plant and animal proteins. Using protein as the switching medium, resistive switching devices have been fabricated with conducting indium tin oxide (ITO) and Al as bottom and top electrodes, respectively. A clockwise bipolar resistive switching phenomenon is observed in all proteins. It is shown that the resistive switching phenomena originate from the local redox process in the protein and the ion exchange from the top electrode/protein interface.

    The importance of studying sex as a biological variable in biomedical research is becoming increasingly apparent. There is a particular need in preclinical studies of addiction to include both sexes, as female animals are often excluded from studies, leaving large gaps in our knowledge of not only sex differences and potential prevention and treatment strategies but also with regard to the basic neurobiology of addiction. This review focuses on methodology that has been developed in preclinical studies to examine sex differences in the behavioral aspects and neurobiological mechanisms related to addiction across the full range of the addiction process, including initiation (acquisition), maintenance, escalation, withdrawal, relapse to drug seeking and treatment. This review also discusses strategic and technical issues that need to be considered when comparing females and males, including the role of ovarian hormones and how sex differences interact with other major vulnerability factors in addiction, such as impulsivity, compulsivity and age (adolescent versus adult). Novel treatments for addiction are also discussed, such as competing non-drug rewards, repurposed medications such as progesterone and treatment combinations. Practical aspects of conducting research comparing female and male animals are also considered. Making sex differences a point of examination requires additional effort and consideration; however, such studies are necessary given mounting evidence demonstrating that the addiction process occurs differently in males and females. These studies should lead to a better understanding of individual differences in the development of addiction and effective treatments for males and females. PMID:27345022

  8. The domestic cat representation in different socio-cultural settings and the connections with animal ethics

    Full Text Available The domestic cat has been symbolically represented over time in a very different way, with connotations sometimes positive and sometimes negative. It is also paradoxical the way that society historically interacts with this feline so, its symbolic representation and its direct interaction with the human seem to go together. In the present, the cat suffers a lot with cruelty acts, abandonment and death, including reduced rate of adoption. Thus, this paper aims to briefly describe the beliefs and ritual uses of cats in different cultures, reflecting on how the symbolism of this feline relates to ethical issues. Education programs and the proper implementation of the laws are identified as important factors to modify this anthropocentric and speciesist paradigm inconsistent with the animal ethics perspectives.

    Candy products are consumed all across the world, but there is not much information about their composition. In this study we have used a DNA-based approach for determining the animal species occurring in 40 commercial candies of different types. We extracted DNA and performed PCR amplification, cloning and sequencing for obtaining species-informative DNA sequences. Eight species were identified including fish (hake and anchovy) in 22% of the products analyzed. Bovine and porcine were the most abundant appearing in 27 samples each one. Most products contained a mixture of species. Marshmallows (7), jelly-types, and gummies (20) contained a significantly higher number of species than hard candies (9). We demonstrated the presence of DNA animal species in candy product which allow consumers to make choices and prevent allergic reaction. PMID:26807698

  10. [Temporal meaning of suffering].

    Science.gov (United States)

    Porée, J

    2015-09-01

    If we had to find a few simple words to express what a suffering human being experiences, no matter what ills are causing the suffering and no matter what circumstances underlie the ills themselves, we could unmistakably say that it is the experience of not being able to go on like this. Suffering can be described, in this same sense, as an alteration in temporality. However, describing suffering as such only makes sense if we already have a conception of normal temporality. Yet for this, philosophical tradition offers not one but four competing conceptions. In the present article, we begin by briefly presenting these different conceptions. We then show how each one sheds light, by way of contrast, on a phenomenon whose meaning thus appears to be essentially negative. But does this phenomenon have a negative meaning only? Doesn't it correspond as much to a transformation as an alteration of temporality? This is what we will strive to establish in the third part of the article by relating suffering to hope, in a paradoxical sense of the term. Of the four conceptions of time likely to shed a contrasting light on the upheavals that suffering introduces into our life experience, the one described by Aristotle in Physics is historically the first. In particular, the notion of succession originates therein. But this conception does not account for what makes time the unit of a past, a present, and a future. In Book XI of Confessions, St. Augustine situated this unit not in nature but in the human mind. Hence, his definition of time as a distension of the soul and the necessary division into physical time and psychic time it entails. Husserl's Lessons on the phenomenology of the consciousness of internal time lend credit to this division, but they illuminate only the internal constitution of the "present", which is at the heart of the psychological conception of time. In Being and Time, Heidegger breaks away from this long-standing tradition; in his view, physical time

    Full Text Available While fasting has been practiced for centuries, its beneficial effects was unknown until recently. This review tries to analyze the current literature of how fasting and intermittent fasting (IF could affect clinical pathological parameters, learning, mood and brain plasticity. The effects of different ways of fasting on metabolism and stress were also explored. Animal experiments have elucidated fasting and IF could exert positive effects on learning, mood and brain, plus metabolic functions such lowering plasma glucose and insulin level and improvement in lipid metabolism (reduced visceral fat tissue and increased plasma adiponectin level, and an increased resistance to stress. Thus, more clinical studies are necessary to test the effectiveness of fasting and IF in preventing different diseases.

    Two isolates of a novel enveloped RNA virus were obtained from carp and koi carp with gill necrosis. Both isolates behaved identically and could be propagated in different cyprinid cell lines forming large syncytia. The virus was sensitive to lipid solvents and neither exhibited haemadsorption/haemagglutination nor reverse transcriptase activity. Mature virus particles displayed a spherical shape with diameter of 100-350 nm after negative staining and 100-300 nm in ultrathin sections, covered by short projections of 8-10 nm in length. Maturation of virus progeny was shown to occur by budding and envelopment of the filamentous helical nucleocapsids at the cell surface. A detailed comparison of ultrastructure and morphogenesis of the novel virus isolates with selected arena-, ortho- and paramyxoviruses as possible candidates for evaluation of taxonomic classification yielded no consistency in all phenotypic features. Thus, on the basis of ultrastructure the novel virus isolates could not be assigned unequivocally to any established virus family. PMID:23865968

    Animal welfare has become a growing concern affecting acceptability of agricultural systems in many countries around the world. An earlier Judeo-Christian interpretation of the Bible (1982) that dominion over animals meant that any degree of exploitation was acceptable has changed for most people to mean that each person has responsibility for animal welfare. This view was evident in some ancient Greek writings and has parallels in Islamic teaching. A minority view of Christians, which is a widespread view of Jains, Buddhists and many Hindus, is that animals should not be used by humans as food or for other purposes. The commonest philosophical positions now, concerning how animals should be treated, are a blend of deontological and utilitarian approaches. Most people think that extremes of poor welfare in animals are unacceptable and that those who keep animals should strive for good welfare. Hence animal welfare science, which allows the evaluation of welfare, has developed rapidly. PMID:25049508

  17. Sex differences in partner preferences in humans and animals.

    Science.gov (United States)

    Balthazart, Jacques

    2016-02-19

    A large number of morphological, physiological and behavioural traits are differentially expressed by males and females in all vertebrates including humans. These sex differences, sometimes, reflect the different hormonal environment of the adults, but they often remain present after subjects of both sexes are placed in the same endocrine conditions following gonadectomy associated or not with hormonal replacement therapy. They are then the result of combined influences of organizational actions of sex steroids acting early during development, or genetic differences between the sexes, or epigenetic mechanisms differentially affecting males and females. Sexual partner preference is a sexually differentiated behavioural trait that is clearly controlled in animals by the same type of mechanisms. This is also probably true in humans, even if critical experiments that would be needed to obtain scientific proof of this assertion are often impossible for pragmatic or ethical reasons. Clinical, epidemiological and correlative studies provide, however, converging evidence strongly suggesting, if not demonstrating, that endocrine, genetic and epigenetic mechanisms acting during the pre- or perinatal life control human sexual orientation, i.e. homosexuality versus heterosexuality. Whether they interact with postnatal psychosexual influences remains, however, unclear at present. PMID:26833838

    In considering pain and suffering, some considerations will appear about epistemological beliefs shaping the clinical practices of health-care workers. With this, we try to understand the usual omission of human suffering in the training of many health professionals. So, we emphasize the role of the pathogenic paradigm in how human suffering is viewed in health care. In contrast to those who see suffering only as pathogenic, we defend that suffering can be a source of significant learning for both the sufferer as well as those who undertake caring in certain circumstances. We therefore argue that it is necessary to educate for health and not only for illness, choosing a holistic paradigm: Aaron Antonovky's salutogenic model that encloses positive aspects of human suffering when it is lived with an internal sense of coherence.

    Despite the recent surge in research linking animal and human acts of violence, relatively few studies have been conducted examining animal cruelty itself. Although several researchers have begun to identify some of the correlates of animal cruelty, few have attempted to understand how differences in the backgrounds of rural and urban residents have led to their abuse of animals. Using survey data from 180 inmates, this study examines how demographic characteristics, exposure to animal cruelty in childhood, and the target animal's relationship with the abuser have contributed to the frequency of acts of animal cruelty in urban- and rural-based settings. Unlike their urban counterparts, rural respondents who engaged in recurrent animal cruelty were more likely to have witnessed family members and/or friends abuse an animal. Moreover, rural respondents who engaged in recurrent animal cruelty abused pet and stray animals, whereas recurrent animal abusers who grew up in urban areas tended to abuse pets only. These findings suggest possible place-based differences in the etiology of recurrent animal cruelty. PMID:21862526

    Epidemiological studies report higher prevalence rates of stress-related disorders such as acute stress disorder and post-traumatic stress disorder (PTSD) in women than in men following exposure to trauma. It is still not clear whether this greater prevalence in woman reflects a greater vulnerability to stress-related psychopathology. A number of individual and trauma-related characteristics have been hypothesized to contribute to these gender differences in physiological and psychological re...

    Although most pharmaceutical heparin used today is obtained from porcine intestine, heparin has historically been prepared from bovine lung and ovine intestine. There is some regulatory concern about establishing the species origin of heparin. This concern began with the outbreak of mad cow disease in the 1990s and was exacerbated during the heparin shortage in the 2000s and the heparin contamination crisis of 2007-2008. Three heparins from porcine, ovine, and bovine were characterized through state-of-the-art carbohydrate analysis methods with a view profiling their physicochemical properties. Differences in molecular weight, monosaccharide and disaccharide composition, oligosaccharide sequence, and antithrombin III-binding affinity were observed. These data provide some insight into the variability of heparins obtained from these three species and suggest some analytical approaches that may be useful in confirming the species origin of a heparin active pharmaceutical ingredient.

  17. Variability driven animacy effects: Evidence of structural, not conceptual differences in processing animates and inanimates

    2010-03-01

    Full Text Available The present eye-tracking study demonstrates that when animate and inanimate object pictures are presented within a single-study, there are no systematic differences between processing these two categories objects. Although participants were taking less time to initiate their first gaze towards animate than to inanimate objects, a result compatible with findings of Proverbio et al. (2007, it turned out that this quicker initiation of the first look in animates was driven by mammals and reptiles only and did not apply to insects or aquatic animals, most probably due to the structural differences within these subcategories. Fixations in this study do not cluster around certain features or areas of the objects for either animate or inanimate categories. Moreover, detailed analysis of looking behaviour does not reveal a clear animateinanimate distinction. Thus, given the failure of finding systematic differences between animates and inanimates when assessed using various looking behaviour measurements, the results do not support the prediction from modality specific conceptual account. In fact, these results are more in agreement with an alternative, distributed account of semantic representation that explains processing differences by structural differences between animate and inanimate objects.

    Several milk metabolites are associated with breeds or species of dairy animals. A better understanding of milk metabolites from different dairy animals would advance their use in evaluating milk traits and detecting milk adulteration. The objective of this study was to characterize the milk metabolite profiles of Chinese Holstein, Jersey, yak, buffalo, goat, camel, and horse and identify any differences using non-targeted metabolomic approaches. Milk samples were tested using nuclear magnetic resonance (NMR) spectroscopy and liquid chromatography-tandem mass spectrometry (LC-MS). Data were analyzed using a multivariate analysis of variance and differences in milk metabolites between Holstein and the other dairy animals were assessed using orthogonal partial least-squares discriminant analysis. Differential metabolites were identified and some metabolites, such as choline and succinic acid, were used to distinguish Holstein milk from that of the other studied animals. Metabolic pathway analysis of different metabolites revealed that glycerophospholipid metabolism as well as valine, leucine, and isoleucine biosynthesis were shared in the other ruminant animals (Jersey, buffalo, yak, and goat), and biosynthesis of unsaturated fatty acids was shared in the non-ruminant animals (camel and horse). These results can be useful for gaining a better understanding of the differences in milk synthesis between Holstein and the other dairy animals. PMID:26779989

    Visual approaches to health information reduce complexity and may bridge challenges in health literacy. But the mechanisms and meanings of using animated video in communication with patients undergoing surgery are not well described. By comparing two versions of a two-dimensional animated video on spinal anesthesia, this study tested the patient-avatar identification within two different narrative models. To explore the perspectives of total hip arthroplasty, we employed qualitative methods of interviews and ethnographic observation. The animated presentation of the spinal anesthesia procedure was immediately recognized by all participants as reflecting their experience of the procedure independent of the narrative form. The avatar gender did not affect this identification. We found no preference for either narrative form. This study supports the potential of animation video in health informatics as a didactic model for qualifying patient behavior. Animation video creates a high degree of identification that may work to reduce pre-surgical anxiety. PMID:25538108

    Since the system of animal world reflects evolutionary trends, an analysis of distribution of patterns of aging over this system provides information on the causes of the formation of differences among them. In this paper the system of the main animal groups in form of a table is presented, and the distribution of patterns demonstrating minimum and maximum of aging is discussed. Meanwhile the colonial animals are considered as a "minimum of aging", the animals demonstrating drastic self-liquidation after reproduction are considered as a "maximum of aging" (the most well-known example is the pink salmon). It is shown, that as far as the degree of difference from the simplest ancestor increases in process of evolution, the increase of the manifestations of aging takes place. Slow aging of relatively simple organisms cannot be a direct source of measures to prevent aging of complex ones. PMID:21957572

    Moral judgment in relation to animal ethics issues has rarely been investigated. Among the research that has been conducted, studies of veterinary students have shown greater use of reasoning based on universal principles for animal than human ethics issues. This study aimed to identify if this was unique to students of veterinary and other animal-related professions. The moral reasoning of first year students of veterinary medicine, veterinary technology, and production animal science was compared with that of students in non-animal related disciplines of human medicine and arts. All students (n = 531) completed a moral reasoning test, the VetDIT, with animal and human scenarios. When compared with reasoning on human ethics issues, the combined group of students evaluating animal ethics issues showed higher levels of Universal Principles reasoning, lower levels of Personal Interest reasoning and similar levels of Maintaining Norms reasoning. Arts students showed more personal interest reasoning than students in most animal-related programs on both animal and human ethics issues, and less norms-based reasoning on animal ethics issues. Medical students showed more norms-based reasoning on animal ethics issues than all of the animal-related groups. There were no differences in principled reasoning on animal ethics issues between program groups. This has implications for animal-related professions and education programs showing that students’ preference for principled reasoning on animal ethics issues is not unique to animal-related disciplines, and highlighting the need to develop student (and professional) capacity to apply principled reasoning to address ethics issues in animal industries to reduce the risk of moral distress.

  5. Gender differences in learning physical science concepts: Does computer animation help equalize them?

    Science.gov (United States)

    Jacek, Laura Lee

    This dissertation details an experiment designed to identify gender differences in learning using three experimental treatments: animation, static graphics, and verbal instruction alone. Three learning presentations were used in testing of 332 university students. Statistical analysis was performed using ANOVA, binomial tests for differences of proportion, and descriptive statistics. Results showed that animation significantly improved women's long-term learning over static graphics (p = 0.067), but didn't significantly improve men's long-term learning over static graphics. In all cases, women's scores improved with animation over both other forms of instruction for long-term testing, indicating that future research should not abandon the study of animation as a tool that may promote gender equity in science. Short-term test differences were smaller, and not statistically significant. Variation present in short-term scores was related more to presentation topic than treatment. This research also details characteristics of each of the three presentations, to identify variables (e.g. level of abstraction in presentation) affecting score differences within treatments. Differences between men's and women's scores were non-standard between presentations, but these differences were not statistically significant (long-term p = 0.2961, short-term p = 0.2893). In future research, experiments might be better designed to test these presentational variables in isolation, possibly yielding more distinctive differences between presentational scores. Differences in confidence interval overlaps between presentations suggested that treatment superiority may be somewhat dependent on the design or topic of the learning presentation. Confidence intervals greatly overlap in all situations. This undercut, to some degree, the surety of conclusions indicating superiority of one treatment type over the others. However, confidence intervals for animation were smaller, overlapped nearly

    Transgenic animal models have revealed much about the pathogenesis of age-dependent neurodegenerative diseases and proved to be a useful tool for uncovering therapeutic targets.Huntington's disease is a well-characterized neurodegenerative disorder that is caused by expansion of a CAG repeat,which results in expansion of a polyglutamine tract in the N-terminal region of huntingtin (HTT).Similar CAG/glutamine expansions are also found to cause eight other neurodegenerative diseases that affect distinct brain regions in an agedependent manner.Identification of this CAG/glutamine expansion has led to the generation of a variety of transgenic animal models.Of these different animal models,transgenic mice have been investigated extensively,and they show similar neuropathology and phenotypes as seen in their respective diseases.The common pathological hallmark of age-dependent neurodegeneration is the formation of aggregates or inclusions consisting of misfolded proteins in the affected brain regions; however,overt or striking neurodegeneration and apoptosis have not been reported in most transgenic mouse models for age-dependent diseases,including HD.By comparing the neuropathology of transgenic HD mouse,pig,and monkey models,we found that mutant HTT is more toxic to larger animals than mice,and larger animals also show neuropathology that has not been uncovered by transgenic mouse models.This review will discuss the importancc of transgenic large animal models for analyzing the pathogenesis of neurodegenerative diseases and developing effective treatments.

  9. Underlying differences between conscientious omnivores and vegetarians in the evaluation of meat and animals.

    2015-04-01

    As criticisms of factory farming continue to mount, an increasing number of individuals have changed their existing dietary practices. Perhaps the two most important options for those reacting against industrial farming are (1) vegetarianism/veganism (i.e., veg*nism), the avoidance of animal flesh/all animal products; and (2) conscientious omnivorism (CO), the consumption of meat or fish only when it satisfies certain ethical standards. While the former group has recently received much attention in the social science literature, studies specifically examining those who identify themselves as COs have been virtually nonexistent. The present research sought to investigate possible underlying attitudinal differences between the two groups. Results indicated that relative to veg*ns, COs evaluated animals less favorably, meat more favorably, and were lower in idealism, misanthropy, and ingroup identification. Mediation analysis demonstrated that differences between COs and veg*ns in the perceived acceptability of killing animals for food were mediated by beliefs about animals and meat. The discussion largely speculates on the causal direction of these effects. PMID:25529819

    Full Text Available Introduction. Correct choice of osteosynthesis method is a very important factor in providing the optimal conditions for appropriate healing of the fracture. There are still disagreements about the method of stabilization of some long bone fractures. Critically observed, no method of fracture fixation is ideal. Each osteosynthesis method has both advantages and weaknesses. Objective. The objective of this study was to compare the results of the experimental application of three different internal fixation methods: plate fixation, intramedullary nail fixation and self-dynamisable internal fixator (SIF. Methods. A series of 30 animals were used (Lepus cuniculus as experimental animals, divided into three groups of ten animals each. Femoral diaphysis of each animal was osteotomized and fixed with one of three implants. Ten weeks later all animals were sacrificed and each specimen underwent histological and biomechanical testing. Results. Histology showed that the healing process with SIF was more complete and bone callus was more mature in comparison to other two methods. During biomechanical investigation (computerized bending stress test, it was documented with high statistical significance that using SIF led to stronger healing ten weeks after the operation. Conclusion. According to the results obtained in this study, it can be concluded that SIF is a suitable method for fracture treatment.

    Full Text Available Serological evidence of hepatitis E virus infection (HEV has been observed in both humans and different animal species living in non-endemic areas, suggesting that animals could be important reservoir for virus transmission to man. Antibodies to HEV have been detected in some Brazilian population groups. Nevertheless, sporadic cases of acute HEV infection have never been reported. We collected 271 serum samples from several domestic animals and also from pig handlers from Southeast of Brazil in order to investigate the seroprevalence of HEV infection. Anti-HEV IgG was detected in cows (1.42%, dogs (6.97%, chickens (20%, swines (24.3%, and rodents (50%, as well as in pig handlers (6.3%. The recognition of swine HEV infections in pigs in many countries of the world led us to investigate a larger sample of pigs (n = 357 from the same Brazilian region with ages ranging from 1 to > 25 weeks. IgG anti-HEV was detected in 100% of 7-day old pigs. Following a gradual decline between weeks 2 and 8 (probably due to loss of maternal IgG, the prevalence then steady increased until it reached 97.3% of animals older than 25 weeks. Besides the detection of anti-HEV antibodies in different animal species, the results showed that swine HEV infection seems to be almost universal within this Brazilian pig population. This is the first report that shows evidences of HEV circulation in Brazilian animal species and pig handlers.

  16. Monte Carlo based performance assessment of different animal PET architectures using pixellated CZT detectors

    International Nuclear Information System (INIS)

    The majority of present position emission tomography (PET) animal systems are based on the coupling of high-density scintillators and light detectors. A disadvantage of these detector configurations is the compromise between image resolution, sensitivity and energy resolution. In addition, current combined imaging devices are based on simply placing back-to-back and in axial alignment different apparatus without any significant level of software or hardware integration. The use of semiconductor CdZnTe (CZT) detectors is a promising alternative to scintillators for gamma-ray imaging systems. At the same time CZT detectors have the potential properties necessary for the construction of a truly integrated imaging device (PET/SPECT/CT). The aims of this study was to assess the performance of different small animal PET scanner architectures based on CZT pixellated detectors and compare their performance with that of state of the art existing PET animal scanners. Different scanner architectures were modelled using GATE (Geant4 Application for Tomographic Emission). Particular scanner design characteristics included an overall cylindrical scanner format of 8 and 24 cm in axial and transaxial field of view, respectively, and a temporal coincidence window of 8 ns. Different individual detector modules were investigated, considering pixel pitch down to 0.625 mm and detector thickness from 1 to 5 mm. Modified NEMA NU2-2001 protocols were used in order to simulate performance based on mouse, rat and monkey imaging conditions. These protocols allowed us to directly compare the performance of the proposed geometries with the latest generation of current small animal systems. Results attained demonstrate the potential for higher NECR with CZT based scanners in comparison to scintillator based animal systems

    The majority of present position emission tomography (PET) animal systems are based on the coupling of high-density scintillators and light detectors. A disadvantage of these detector configurations is the compromise between image resolution, sensitivity and energy resolution. In addition, current combined imaging devices are based on simply placing back-to-back and in axial alignment different apparatus without any significant level of software or hardware integration. The use of semiconductor CdZnTe (CZT) detectors is a promising alternative to scintillators for gamma-ray imaging systems.

    2010-04-01

    Full Text Available The aims of the present study were to compare estimated breeding values (EBV for milk yield using different testing schemes with a test-day animal model and to evaluate the effect of different testing schemes on the ranking of top sheep. Alternative recording schemes that use less information than that currently obtained with a monthly test-day schedule were employed to estimate breeding values. A random regression animal mixed model that used a spline function of days in milk was fitted. EBVs obtained with alternative recording schemes showed different degrees of Spearman correlation with EBVs obtained using the monthly recording scheme. These correlations ranged from 0.77 to 0.92. A reduction in accuracy and intensity of selection could be anticipated if these alternative schemes are used; more research in this area is needed to reduce the costs of test-day recording.

  1. Sex differences in animal models of schizophrenia shed light on the underlying pathophysiology.

    2016-08-01

    Sex differences in schizophrenia are apparent in almost all features of the illness, from incidence and mean age of onset to symptomatology, course of illness and response to pharmacological treatments. Understanding how men and women with schizophrenia differ provides significant clues into the pathophysiology of the disorder. Animal models are powerful tools when dissecting the molecular biology which underlies behavioural disturbances, and allow structured comparisons of biological sex differences without the social environmental gender influence that so often confounds human sex comparison studies. This review will provide a summary of sex differences described in developmental, genetic and drug-induced animal models of schizophrenia and will link sex-specific molecular and behavioural phenotypes of these models in an attempt to unravel the role that sex plays in the pathophysiology of schizophrenia. Both sex and stress hormones interact to shape the developing brain and behaviour and animal models of schizophrenia that include both sexes provide significant insight into the complexities of these interactions and can direct toward novel therapeutic strategies.

    Business models for transnational organizations include linking different geographies through common codes of conduct, policies, and virtual teams. Global companies with laboratory animal science activities (whether outsourced or performed inhouse) often see the need for these business activities in relation to animal-based research and benefit from them. Global biomedical research organizations can learn how to better foster worldwide cooperation and teamwork by understanding and working with sociocultural differences in ethics and by knowing how to facilitate appropriate virtual team actions. Associated practices include implementing codes and policies transcend cultural, ethnic, or other boundaries and equipping virtual teams with the needed technology, support, and rewards to ensure timely and productive work that ultimately promotes good science and patient safety in drug development.

  4. Boron neutron capture therapy as new treatment for clear cell sarcoma: Trial on different animal model

    International Nuclear Information System (INIS)

    Clear cell sarcoma (CCS) is a rare malignant tumor with a poor prognosis. In our previous study, the tumor disappeared under boron neutron capture therapy (BNCT) on subcutaneously-transplanted CCS-bearing animals. In the present study, the tumor disappeared under this therapy on model mice intramuscularly implanted with three different human CCS cells. BNCT led to the suppression of tumor-growth in each of the different model mice, suggesting its potentiality as an alternative to, or integrative option for, the treatment of CCS. - Highlights: • BNCT with the use of L-BPA was applied for three human clear cell sarcoma (CCS) cell lines. • BNCT trial was performed on a newly established intramuscularly CCS-bearing animal model. • A significant decrease of the tumor-volume was seen by single BNCT with the use of L-BPA. • A multiple BNCT application would be required for controlling the growth of any residual tumors

  6. How humans differ from other animals in their levels of morphological variation.

    Directory of Open Access Journals (Sweden)

    Ann E McKellar

    Full Text Available Animal species come in many shapes and sizes, as do the individuals and populations that make up each species. To us, humans might seem to show particularly high levels of morphological variation, but perhaps this perception is simply based on enhanced recognition of individual conspecifics relative to individual heterospecifics. We here more objectively ask how humans compare to other animals in terms of body size variation. We quantitatively compare levels of variation in body length (height and mass within and among 99 human populations and 848 animal populations (210 species. We find that humans show low levels of within-population body height variation in comparison to body length variation in other animals. Humans do not, however, show distinctive levels of within-population body mass variation, nor of among-population body height or mass variation. These results are consistent with the idea that natural and sexual selection have reduced human height variation within populations, while maintaining it among populations. We therefore hypothesize that humans have evolved on a rugged adaptive landscape with strong selection for body height optima that differ among locations.

    2009-07-01

    Full Text Available Abstract Background Borreliae employ multiple immune evasive strategies such as binding to complement regulatory proteins [factor H (fH and factor H like-1 (FHL1], differential regulation of surface membrane proteins, antigenic variation, and binding of plasminogen/plasmin and matrix metalloproteinases. As a complement regulatory subunit, fH serves as a cofactor for the factor I-mediated cleavage of C3b. fH binding by Borrelia has been correlated with pathogenesis as well as with host diversity. Here we show the differential binding of borrelial proteins to fH from human and animal sera. Findings Affinity ligand binding experiments, 2-D electrophoresis, and protein identification and peptide de novo sequencing based on mass spectrometry, revealed novel fH putative binding proteins of Lyme- and relapsing fever Borrelia. An OspA serotype-associated differential human and animal fH binding by B. garinii was also observed, which could be related with the ability of some strains from serotypes 4 and 7 to invade non-nervous system tissues. Also, the variable affinity of binding proteins expressed by different Borrelia to animal fH correlated with their host selectivity. Conclusion The novel animal and human putative fH binding proteins (FHBPs in this study underscore the importance of evasion of complement in the pathogenesis of Borrelia infections.

  9. Prioritizing Zoonotic Diseases: Differences in Perspectives Between Human and Animal Health Professionals in North America.

    2016-05-01

    Zoonoses pose a significant burden of illness in North America. Zoonoses represent an additional threat to public health because the natural reservoirs are often animals, particularly wildlife, thus eluding control efforts such as quarantine, vaccination and social distancing. As there are limited resources available, it is necessary to prioritize diseases in order to allocate resources to those posing the greatest public health threat. Many studies have attempted to prioritize zoonoses, but challenges exist. This study uses a quantitative approach, conjoint analysis (CA), to overcome some limitations of traditional disease prioritization exercises. We used CA to conduct a zoonoses prioritization study involving a range of human and animal health professionals across North America; these included epidemiologists, public health practitioners, research scientists, physicians, veterinarians, laboratory technicians and nurses. A total of 699 human health professionals (HHP) and 585 animal health professionals (AHP) participated in this study. We used CA to prioritize 62 zoonotic diseases using 21 criteria. Our findings suggest CA can be used to produce reasonable criteria scores for disease prioritization. The fitted models were satisfactory for both groups with a slightly better fit for AHP compared to HHP (84.4% certainty fit versus 83.6%). Human-related criteria were more influential for HHP in their decision to prioritize zoonoses, while animal-related criteria were more influential for AHP resulting in different disease priority lists. While the differences were not statistically significant, a difference of one or two ranks could be considered important for some individuals. A potential solution to address the varying opinions is discussed. The scientific framework for disease prioritization presented can be revised on a regular basis by updating disease criteria to reflect diseases as they evolve over time; such a framework is of value allowing diseases of

    Full Text Available A comparative study on the sensitivity of erythrocytes from different vertebrate species (avian, mammalian and reptilian to the hemolytic action caused by cardiotoxin isolated from Naja naja atra venom was carried out. Cardiotoxin was able to induce direct hemolysis in washed erythrocytes from several animals, except for llama. The EC50 values from hemolysis of the most sensitive (cat and the most resistant (snake animal varied approximately tenfold. According to the cell behavior, it was possible to characterize four types of behavior: The first was observed in cat, horse and human cells; the second in rat, rabbit and dog erythrocytes; and the third only in llama erythrocytes, which were resistant to cardiotoxin concentrations up to 300 µg/ml. Finally, avian and reptilian erythrocytes were more resistant to cardiotoxin III-induced hemolysis than those of the mammalian species.

    Full Text Available In study of more efficient animals for food utilization, it is of great importance to know differences between genders. There are differences between male and female cattle in growing and body composition, mainly those related to the action of sex hormones. This study aimed to evaluate the sex effect on feed efficiency traits in young Nellore animals. Individual feed intake data from eight tests, performed from 2005 to 2012 at Centro APTA Bovinos de Corte-Instituto de Zootecnia-Sertãozinho-SP were utilized. The tests began after weaning, when the animals had, on average, 286 days of age and 229 kg of body weight. The tests duration ranged from 56 to 112 days, depending on the year. Traits analyzed were final body weight (FBW, dry matter intake (DMI, average daily gain (ADG, feed conversion ratio (FCR, feed efficiency ratio (FER, residual feed intake (RFI and Kleiber ratio (KR. Data were analyzed using the MIXED procedure of SAS. The model included the fixed effect age at the test beginning as linear covariate and the random effects: sex, facilities and year. Least square means were calculated and compared by t test. Males had greater FBW than females, what was expected, due to the action of male hormones which benefits the muscle deposition. Greater means of ADG and DMI were also detected for males, when compared to females, because heavier animals have higher gains and consume food according to their body sizes. Among all the feed efficiency measures studied, significant differences between males and females were detected in FCR and KR. Analyzing FCR, females used more food than males for 1 kg of body weight gain, being less efficient. The same was found when KR was analyzed, having males higher KR and being more efficient. No significant differences were detected between males and females for FER and RFI. Young Nellore females are less efficient than males in this growth stage, because of the differences in growth curves due to the sex

    Cell movement in the amoebae Dictyostelium discoideum has been examined in media differing in monovalent cation concentration (i.e. Na+ and K+). Under isotonic or even slightly hypertonic conditions, the cells move equally well in solutions in which either potassium or sodium ions dominate. However, in strongly hypertonic solutions the amoebae showed motility in a 2% potassium chloride solution, but remained motionless in a hypertonic 2% sodium chloride solution. This inhibition of D. discoideum amoebae movement in a hypertonic sodium chloride solution was fully reversible. Such behaviour corresponds to that of plant, fungi, and some invertebrate animal cells rather than protozoan or vertebrate cells. These observations suggest that studies using D. discoideum as a model for cell motility in vertebrate animal tissue cells should be considered with caution, and would seem to confirm the classification of cellular slime moulds as related rather to Fungi than to Protista. This also shows that the cell membrane models should consider the asymmetry in sodium/potassium ion concentrations found in vertebrate animal cells as one of various possibilities. PMID:18274250

    Encephalitozoon cuniculi is an obligate intracellular microsporidian parasite that infects a wide range of mammalian hosts. The present study investigated the prevalence of E. cuniculi in different animal hosts from different provinces of Egypt (Alexandria, Behera, and Assuit) using serological (IFAT and ELISA) and molecular (PCR) assays. A total of 324 serum and 274 urine samples were collected from seven different species of animals (cattle, buffaloes, sheep, goat, rabbit, dog, and rat). The results of serological examination confirmed the occurrence of antibodies against E. cuniculi in 38.9 % (126 out of 324) of the examined animals. The significant (P < 0.01) highest positivity was observed in goats (67 %) followed by buffaloes, rabbits, dogs, rat, and cattle (46.42, 41, 40, 36.2, and 28.1 %, respectively), while the least was recorded in sheep (9 %). Behera province showed the highest (P < 0.01) infection rate (40.68 %) followed by Alexandria and Assuit (39.2 and 22.73 %, respectively). The infection rate was significantly higher (P < 0.01) in females (45.34 %) than that in males (30.47 %). Positive cases were observed in all age categories. The highest infection rate (64.66 %) was recorded in the age group 1-5 years and the least was recorded in the age group <1 year (34.85 %).On the other hand, only five positive out of 274 urine samples (1.82 %) were detected by PCR. Our study provides a wide database on prevalence and epidemiology of an ignored parasite (E. cuniculi) for the first time in Egypt. PMID:25547075

  17. Sex differences and ovarian hormones in animal models of drug dependence.

    2010-06-01

    Increasing evidence indicates the presence of sex differences in many aspects of drug abuse. Most studies reveal that females exceed males during the initiation, escalation, extinction, and reinstatement (relapse) of drug-seeking behavior, but males are more sensitive than females to the aversive effects of drugs such as drug withdrawal. Findings from human and animal research indicate that circulating levels of ovarian steroid hormones account for these sex differences. Estrogen (E) facilitates drug-seeking behavior, while progesterone (P) and its metabolite, allopregnanalone (ALLO), counteract the effects of E and reduce drug seeking. Estrogen and P influence other behaviors that are affiliated with drug abuse such as drug-induced locomotor sensitization and conditioned place preference. The enhanced vulnerability to drug seeking in females vs. males is also additive with the other risk factors for drug abuse (e.g., adolescence, sweet preference, novelty reactivity, and impulsivity). Finally, treatment studies using behavioral or pharmacological interventions, including P and ALLO, also indicate that females show greater treatment effectiveness during several phases of the addiction process. The neurobiological basis of sex differences in drug abuse appears to be genetic and involves the influence of ovarian hormones and their metabolites, the hypothalamic pituitary adrenal (HPA) axis, dopamine (DA), and gamma-hydroxy-butyric acid (GABA). Overall, sex and hormonal status along with other biological risk factors account for a continuum of addiction-prone and -resistant animal models that are valuable for studying drug abuse prevention and treatment strategies.

    We examined the effects of different shift work schedules and chronic mild stress (CMS) on mood using animal model. The most common international shift work schedules in nursing were applied by three groups of Wistar-rats and a control group with normal light-dark cycle. One subgroup from each group was subjected to CMS. Levels of anxiety and emotional life were evaluated in light-dark box. Differences between the groups according to independent and dependent variables were examined with one- and two-way analysis of variance, with a significance level defined at p examination confirm that the changes of lighting conditions evocate anxiety more prominently than CMS. No significant differences were found between the results of the low rotating group and the control group, supposing that this schedule is the least harmful to health. Our results on the association between the use of lighting regimens and the level of CMS provide evidence that the fast rotating shift work schedule puts the heaviest load on the organism of animals.

    1998-01-01

    Under the pressure of a public vote in Switzerland (7 June 1998) on an initiative to ban the production, use and patenting of transgenic animals, their value for biomedical research and development is intensely debated. In addition, the Swiss legislation has adopted (1992) a constitutional obligation to "take into account the dignity of creatures". The term "dignity of creatures", however, can be interpreted in anthropocentric or biocentric ways. The government has now formulated the legal implications of this term for transgenic animals and plants in various laws including the animal and environmental protection laws. This paper gives arguments for a fair evaluation of trangenic animals from an animal welfare point of view where not only the costs of animal suffering must be considered but also the probability of potential benefit for man. A self-confident research community should allow such an evaluation procedure even in view of an outcome which could ban many uses of transgenic animals PMID:11208266

    Full Text Available Umbilical cord mesenchymal stromal cells (MSC have been widely investigated for cell-based therapy studies as an alternative source to bone marrow transplantation. Umbilical cord tissue is a rich source of MSCs with potential to derivate at least muscle, cartilage, fat, and bone cells in vitro. The possibility to replace the defective muscle cells using cell therapy is a promising approach for the treatment of progressive muscular dystrophies (PMDs, independently of the specific gene mutation. Therefore, preclinical studies in different models of muscular dystrophies are of utmost importance. The main objective of the present study is to evaluate if umbilical cord MSCs have the potential to reach and differentiate into muscle cells in vivo in two animal models of PMDs. In order to address this question we injected (1 human umbilical cord tissue (hUCT MSCs into the caudal vein of SJL mice; (2 hUCT and canine umbilical cord vein (cUCV MSCs intra-arterially in GRMD dogs. Our results here reported support the safety of the procedure and indicate that the injected cells could engraft in the host muscle in both animal models but could not differentiate into muscle cells. These observations may provide important information aiming future therapy for muscular dystrophies.

    Hypothalamic-pituitary-adrenal (HPA) axis dysfunction has been implicated in depression pathology. In the present study, we used a chronic mild stress (CMS) animal model of depression to examine the responses of three strains of rats that have different HPA axis responsiveness; and whether the behavioral changes observed are correlated with changes in hippocampal cell proliferation and survival. In addition, in most of the CMS experiments the rats are kept in singly housed condition. Since rats are social animals we also examined whether prolonged single housing condition affects the behavior of the rats. The results showed that rats with a hyperactive HPA axis, the inbred Fischer (F344) rat, were the most responsive to CMS. The inbred Lewis (LEW) rat, which has a hypoactive HPA axis, did not show anhedonia after CMS treatment but showed other signs of distress. The responses of the outbred Sprague-Dawley (SD) rats were variable; this strain was very sensitive to the single housing condition. Prolonged single housing condition itself could induce helplessness behavior in the rats. The results from hippocampal cell proliferation of the three strains indicated that cell proliferation was not related to anhedonia induced by CMS. We conclude that F344 rat is the strain most sensitive to CMS treatment and is probably the stain of choice for CMS experiments. PMID:20438768

  6. Analysis of animal experiments of radiation dependent tumor regression in relation to different parameters

    International Nuclear Information System (INIS)

    In order to be able to test the therapeutic value of the pions in comparison with conventional X-rays, analyses of animal experiments with induced tumors, transplantation tumors, and comparative cellular kinetic studies of tissue cultures will be performed. So that differences in radiation effect and a possible superiority of the pion therapy be objectively acknowledged, the reaction systems to be tested must be as homogenous as possible. For this purpose, the dependence of the radiation related regression on various parameters such as sex, age of hosts, environmental factors radiation conditions (intensity, fractionation, and so on), tumor size, and so on, must be investigated on sterile animals in a sterile environment. The experiments should be conducted under conditions as close as possible to clinical ones. For comparison, the reaction of normal tissue (in vitro and in vivo) and of malignant cells in short-time tissue cultures will be analysed. Cellular kinetics, alteration of chromosomes and metabolic activity of the cells will be studied

    Metallothioneins play a key role in maintaining homeostasis of essential metals and in protecting of cells against metal toxicity as well as oxidative damaging. Excepting humans, blood levels of metallothionein have not yet been reported from any animal species. Blood plasma samples of 9 animal species were analysed by the adsorptive transfer stripping technique to obtain species specific voltammograms. Quite distinct records were obtained from the Takin (Budorcas taxicolor), while other interesting records were observed in samples from the European Bison (Bison bonasus bonasus) and the Red-eared Slider (Trachemys scripta elegans). To quantify metallothionein the catalytic peak Cat2 was used, well developed in the Domestic Fowl (Gallus gallus f. domestica) and showing a very low signal in the Red Deer (Cervus elaphus). The highest levels of metallothionein reaching over 20 µM were found in the Domestic Fowl. High levels of MT were also found in the Bearded Dragon (Pogona vitticeps) and the Grey Wolf (Canis lupus lupus). The lowest values of about 1-3 µM were determined in the Red-eared Slider, Takin and Red Deer. Employing a simple electrochemical detection it was possible to examine variation in blood metallothionein in different species of vertebrates.

    Following the Gardners' discovery that an ape named Washoe could learn to produce and combine a number of hand movements similar to those used by deaf human beings, a variety of 'ape-language projects' sprang up. Some projects used different symbol systems, others used different training techniques, and others used different species of apes. While debate still rages regarding the appropriate way to interpret the symbolic productions of apes, three species of great apes (gorilla, orangutan, and chimpanzee) have now been credited with this capacity while no lesser apes or monkeys have been reported, at present, to have acquired such communicative skills. Among all of the claims made for the various animal species, the philosophers have entered the fray attempting to define the essence of what it is about language that makes it 'human'. This paper will compare and contrast the above positions to arrive at behavioural definitions of symbolic usage that can be applied across species. It will then present new data on a fourth ape species Pan paniscus which is proving to be the first non-human species to acquire symbolic skills in a spontaneous manner. PMID:2858874

    Full Text Available A study was carried out to compare partial acylglycerols of lard with those of chicken fat, beef fat and mutton fat using Gas Chromatography Mass Spectrometry (GC-MS and Elemental Analysis–Isotope Ratio Mass Spectrometry (EA-IRMS. Mono- (MAG and di-(DAG acylglycerols of animal fats were prepared according to a chemical glycerolysis method and isolated using column chromatography. The fatty acid composition and δ13C carbon isotope ratio of MAG and DAG derived from individual animal fat were determined separately to establish their identity characteristics. The results showed that the δ13C values of MAG and DAG of lard were significantly different from those of MAG and DAG derived from chicken fat, beef fat and mutton fat. According to the loading plots based on a principle component analysis (PCA, fatty acids namely stearic, oleic and linoleic were the most discriminating parameters to distinctly identify MAG and DAG derived from different animal fats. This demonstrated that the EA-IRMS and the PCA of fatty acid data have considerable potential for discriminating MAG and DAG derived from lard from other animal fats for Halal authentication purposes.Se realizó un estudio para comparar acilgliceroles parciales de la manteca de cerdo con las de grasa de pollo, grasa de vacuno y grasa de cordero utilizando cromatografía de gases-espectrometría de masas (GC-MS y análisis elemental de Isótopos-Espectrometría de Masas (EA-IRMS.

  13. Radiation dosimetry in experimental animals exposed to tritiated water under different conditions

    International Nuclear Information System (INIS)

    The radiation dose to the germ cells of male mice, which sired the offspring scored in a specific-locus mutation test of injected tritiated water, was calculated. The weighted mean dose for germ cells which received all of the radiation at postspermatogonial stages was 430 rads, while that for germ cells irradiated almost entirely as spermatogonia was 615 rads. Most of the animals received a single intraperitoneal injection of HTO of 0.50 mCi/g body weight, but a few of them received 00.75 mCi/g. These weighted mean doses reflect the contribution of both groups. The percentage of the total dose delivered from 3H incorporated into macromolecules is small - less than 0.5%. The percentage of the total radioactivity in dry material from the testis on day 1 postinjection is 0.6%, on day 7 it is 3.2%, and on day 605 it is 95%. Tritium is incorporated into testicular DNA from tritiated water, and peak levels of radioactivity in this macromolecule are reached from 3 to 9 days following injection. The stable incorporation of tritium into trichloracetic acid insoluble materials is about 75% in protein and 25% in nucleic acids at all time periods following injection. Doses from single injections of tritiated water are inherently more variable than for protracted low-level exposures. This is because small differences in water balance near the time of injection can make a very large difference in total radiation dose

    Full Text Available Listeria species were isolated from faecal samples collected from different captive wild animals of Nandankanan Zoo, Baranga, Odisha, using selective enrichment medium. The isolates were characterized based on their cell morphology, biochemical and sugar fermentation characteristics as well as culture morphology. Further, in vitro and in vivo pathogenicity tests were carried out to assess the pathogenic potential of the isolates. Listeria were found in 24 (23.07% of the total 104 faecal samples. Listeria were isolated from the samples of tiger, bear, hyena, leopard, zebra, elephant, jackal, lion, barking deer, porcupine, chital, monkey and wild boar. Out of the 24 Listeria isolates 11 were confirmed as L. monocytogenes. The other 13 isolates included L. innocua, L. seeligeri, L. welshimeri and L. ivanovii. The pathogenicity study revealed that only four isolates were pathogenic. Three of these were L. monocytogenes isolated from tiger, hyena and elephant and one was L. ivanovii isolated from leopard. Antibiotic sensitivity of the 24 isolates was high towards ciprofloxacin, levofloxacin, amoxicillin, azithromycin and enrofloxacin. The isolates showed resistance towards oxytetracyclin, gentamicin, cephadroxil, penicillin- G and nalidixic acid.

    Full Text Available In this study we monitored antibiotic resistance in Enterobacteriaceae strains isolated from different animals gastrointestinal tracts  (GIT. We isolated Enterobacteriaceae from chicken, ducks, lambs, pigs, sheeps, cows and rabbits collected from slovakian farms. Enterobacteriaceae strains were cultivated on MacConkey agar at 35° ± 2°C at 24 hours. Pure cultures of Enterobacteriaceae strains were obtained by four-way streak method on Chromogenic coliform agar. Identification of purified Enterobacteriaceae strains were done by Enterotest 24 and MALDI TOF MS. For susceptibility testing disk diffusion method was used according by EUCAST. We determined the most resistance in Enterobacteriaceae strains against streptomycin, tetracycline, ampicillin, piperecillin, levofloxacine, chloramphenicol and smaller level of resistance against amikacin, ceftriaxone and ofloxacine. Equally we detected resistance to more antibiotics in one strain. The most resistance was Salmonella enterica ser. Typhimurium. Also E. coli was resistance against four antibiotics and Raoultella ornithinolytica too. Antibiotic resistance was found in other isolated strains too.

  17. Evaluation of different techniques to control hydrogen sulfide and greenhouse gases from animal production systems

    Gautam, Dhan Prasad

    The livestock manure management sector is one of the prime sources for the emission of greenhouse gases (GHGs) and other pollutant gases such as ammonia (NH3) and hydrogen sulfide (H2S), which may affect the human health, animal welfare, and the environment. So, worldwide investigations are going on to mitigate these gaseous emissions. The overall objective of this research was to investigate different approaches (dietary manipulation and nanotechnology) for mitigating the gaseous emissions from livestock manure system. A field study was conducted to investigate the effect of different levels of dietary proteins (12 and 16%) and fat levels (3 to 5.5%) fed to beef cattle on gaseous emission (methane-CH4, nitrous oxide-N2O, carbon dioxide-CO 2 and hydrogen sulfide-H2S) from the pen surface. To evaluate the effects of different nanoparticles (zinc oxide-nZnO; and zirconium-nZrO 2) on these gaseous emissions from livestock manure stored under anaerobic conditions, laboratory studies were conducted with different treatments (control, bare NPs, NPs entrapped alginate beads applying freely and keeping in bags, and used NPs entrapped alginate beads). Field studies showed no significant differences in the GHG and H2S emissions from the manure pen surface. Between nZnO and nZrO2, nZnO outperformed the nZrO2 in terms of gases production and concentration reduction from both swine and dairy liquid manure. Application of nZnO at a rate of 3 g L-1 showed up to 82, 78, 40 and 99% reduction on total gas production, CH 4, CO2 and H2S concentrations, respectively. The effectiveness of nZnO entrapped alginate (alginate-nZnO) beads was statistically lower than the bare nZnO, but both of them were very effective in reducing gas production and concentrations. These gaseous reductions were likely due to combination of microbial inhibition of microorganisms and chemical conversion during the treatment, which was confirmed by microbial plate count, SEM-EDS, and XPS analysis.

    For whole-body computed tomography (CT) images of small rodents, a voxel resolution of at least 10 -3 mm 3 is needed for scale-equivalence to that currently achieved in clinical CT scanners (˜1 mm 3) in adult humans. These "mini-CT" images generally require minutes rather than seconds to complete a scan.

Hence, these scans are useful for performing clinical-type diagnostic and monitoring scans for animal models of disease and their response to treatment.

    For whole-body computed tomography (CT) images of small rodents, a voxel resolution of at least 10-3 mm3 is needed for scale-equivalence to that currently achieved in clinical CT scanners (∼1 mm3) in adult humans. These 'mini-CT' images generally require minutes rather than seconds to complete a scan. The radiation exposure resulting from these mini-CT scans, while higher than clinical CT scans, is below the level resulting in acute tissue damage. Hence, these scans are useful for performing clinical-type diagnostic and monitoring scans for animal models of disease and their response to treatment. 'Micro-CT', with voxel size -5 mm3, has been useful for imaging isolated, intact organs at an almost cellular level of resolution. Micro-CT has the great advantage over traditional microscopic methods in that it generates detailed three-dimensional images in relatively large, opaque volumes such as an intact rodent heart or kidney. The radiation exposure needed in these scans results in acute tissue damage if used in living animals. Experience with micro-CT is contributing to exploration of new applications for clinical CT imaging by providing insights into different modes of X-ray image formation as follows: (1)Spatial resolution should be sufficient to detect an individual Basic Functional Unit (BFU, the smallest collection of diverse cells, such as hepatic lobule, that behaves like the organ), which requires voxels ∼10-3 mm3 in volume, so that the BFUs can be counted.

    Advanced and progressive illnesses bring existential suffering to patients as an inevitable consequence of the disease and its treatment. Physicians need a typology of existential distress to aid its recognition and improved management. The major forms of existential challenge include (1) death anxiety, (2) loss and change, (3) freedom with choice or loss of control, (4) dignity of the self, (5) fundamental aloneness, (6) altered quality of relationships, (7) our search for meaning, and (8) mystery about what seems unknowable. An adaptive response to each challenge promotes equanimity, peace, and fulfillment while sustaining engagement with life, creativity, and joy. Physicians can do much to nurture courage and maintain each person's sense of meaning, value, and purpose. PMID:22945389

    We investigated the animal and human baby schema effect (BSE) in relation to gender, parental status, and individual features. In three, independent online surveys, conducted during three consecutive years, (Ntotal=1389), ratings of photographs of human and animal infants as well as of adults, sociodemographic variables (age, gender, parental status) and personality attributes (empathy, attachment, interpersonal closeness, narcissism, and need to belong) were assessed. We demonstrated that humans are sensitive to the baby schemata of both humans and animals and that both are weakly positively correlated. BSE is positively associated with female gender and (affective) empathy. Higher interpersonal closeness and need to belong were additionally connected specifically to the human BSE. In contrast, narcissism and insecure attachment were not related to the BSE, suggesting a robustness of this phenomenon to possible negative influences of these two personality attributes.

    Monin, Joan K.; Schulz, Richard

    2009-01-01

    Examining the interpersonal effects of suffering in the context of family caregiving is an important step to a broader understanding of how exposure to suffering affects humans. In this review article, we first describe existing evidence that being exposed to the suffering of a care recipient (conceptualized as psychological distress, physical symptoms, and existential/spiritual distress) directly influences caregivers’ emotional experiences. Drawing from past theory and research, we propose that caregivers experience similar, complementary, and/or defensive emotions in response to care recipient suffering through mechanisms such as cognitive empathy, mimicry, and conditioned learning, placing caregivers at risk for psychological and physical morbidity. We then describe how gender, relationship closeness, caregiving efficacy, and individual differences in emotion regulation moderate these processes. Finally, we provide directions for future research to deepen our understanding of interpersonal phenomena among older adults, and we discuss implications for clinical interventions to alleviate the suffering of both caregivers and care recipients.

    Full Text Available Electrical water bath stunning is the most commonly used method for poultry stunning prior to slaughter, but has been questioned on animal welfare and product quality grounds. Controlled atmosphere stunning (CAS methods, involving a variety of gas mixtures, have become increasingly common, at least in Europe. CAS methods have been perceived as an improvement from an animal welfare perspective, partly because birds can be stunned without prior shackling, and are generally considered to result in improved product quality compared to water bath stunning. However, there would still be an interest in alternative stunning methods especially for small to medium size poultry slaughterhouses. This review presents an overview of the modes of action and the technical aspects of poultry stunning methods, including novel and emerging stunning technologies.

    Genetic defects in a number of components of the dystrophin–glycoprotein complex (DGC) lead to distinct forms of muscular dystrophy. However, little is known about how alterations in the DGC are manifested in the pathophysiology present in dystrophic muscle tissue. One hypothesis is that the DGC protects the sarcolemma from contraction-induced damage. Using tracer molecules, we compared sarcolemmal integrity in animal models for muscular dystrophy and in muscular dystrophy patient samples. Ev...

    2010-01-01

    A laboratory study of older adults with osteoarthritis and their spouses was conducted to examine the unique influence of exposure to suffering on caregivers’ risk for impaired psychological and physical health. Spouses’ blood pressure (BP) and heart rate (HR) were monitored during 2 tasks designed to capture their partners’ suffering. First, spouses watched their partners (and a stranger) carry heavy logs across an 8-ft space for 3 min, a task that elicited pain expression. Second, spouses spoke about their partners’ suffering (and also about a typical meal with their partners). Results showed that spouses’ BP and HR increased when watching and talking about their partners’ suffering, and exposure to a partner’s suffering was more physiologically stressful than to a stranger’s suffering. These findings suggest that heightened physiological stress caused by exposure to a loved one’s suffering may be one pathway to caregivers’ increased risk for cardiovascular disease. PMID:20067977

    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.

    Erick Saldaña

    2015-12-01

    Full Text Available Meat has played a crucial role in human evolution and is an important component of a healthy and well-balanced diet on account of its nutritional properties, its high biological value as a source of protein, and the vitamins and minerals it supplies. We studied the effects of animal fat reduction and substitution by hydrogenated vegetal fat, sodium alginate and guar gum. Fatty acid composition, lipid oxidation, color and instrumental texture as well as the sensorial difference between low, substituted-fat and the traditional formulations for mortadella-type products were analyzed. Both substitution and reduction of animal fat decreased the saturated fatty acids percentage from 40% down to 31%. A texture profile analysis showed differences between the formulations. Furthermore, lipid oxidation values were not significant for treatments as regards the type and quantity of fat used while the use of sodium alginate and guar gum reduced the amounts of liquid released after cooking. Animal fat substitution does cause, however, a difference in overall sensorial perception compared with non-substituted products. The results confirm the viability of substituting vegetal fat for animal fat.

    Full Text Available Prenatal ethanol exposure (PNEE has been linked to widespread impairments in brain structure and function. There are a number of animal models that are used to study the structural and functional deficits caused by prenatal ethanol exposure, including, but not limited to: invertebrates, fish, rodents and non-human primates. Animal models enable a researcher to control important variables such as the route of ethanol administration, as well as the timing, frequency and amount of ethanol exposure. Each animal model and system of exposure has its place, depending on the research question being undertaken. In this review we will examine the different routes of ethanol administration and the various animal models of FASD that are commonly used in research, emphasizing their strengths and limitations. We will also present an up-to-date summary on the effects of prenatal/neonatal ethanol exposure on behavior across the lifespan, focusing on learning and memory, olfaction, social, executive and motor functions. Special emphasis will be placed where the various animal models best represent deficits observed in the human condition and offer a viable test bed to examine potential therapeutics for humans with FASD.

    The aim of the study was to monitor Y. enterocolitica strains from free-living animals captured during 2011-2014 hunting seasons in Poland using warm (ITC) and cold (PSB) enrichment and molecular examination. Over 1600 samples have been cultured. After ITC/PSB enrichment 237 strains presenting features characteristic for Y. enterocolitica were isolated. Molecular examination using multiplex PCR revealed 140 isolates from PSB and 78 from ITC. The concentration of pathogenic Yersinia in asymptomatic carriers is low and the PCR detection should be preceded by bacteriological examination. PMID:27096808

    Quantitative detection of magnetic nanoparticles (MP) in vivo is very important for various biomedical applications. Our original detection method based on non-linear MP magnetization has been modified for non-invasive in vivo mapping of the MP distribution among different organs of rats. A novel highly sensitive room-temperature device equipped with an external probe has been designed and tested for quantification of MP within 20-mm depth from the animal skin. Results obtained by external in vivo scanning of rats by the probe and ex vivo MP quantification in different organs of rats well correlated. The method allows long-term in vivo study of MP evolution, clearance and redistribution among different organs of the animal. Experiments showed that dynamics in vivo strongly depend on MP characteristics (size, material, coatings, etc.), site of injection and dose. The developed detection method combined with the magnetic nanolabels can substitute the radioactive labeling in many applications.

    Full Text Available The objective of our study is the sensory characterisation of buffalo meat from animals fed with different diets. The sensory evaluation was carried out on frozen rump meat samples from 12 animals. Control group (N=4 received a normal diet, a low vitamin E diet group (LVE (N=4 and a high vitamin E diet group (HVE (N=4. The sensory profiles of the different samples were obtained by Quantitative Descriptive Analysis. Sensory evaluation was initially carried out on the raw meat. The samples were cooked using an electrical oven reaching an inner temperature of 80°C. The slices were cut into squared pieces of 2x2 cm for tasting. A detailed analysis of the profiles for each attribute shows that the “tenderness”, “juiciness” and “visible fat” of the LVE group are significantly greater when compared to the Control and HVE groups. While HVE animal rump has a higher “cohesivity” and “colour uniformity” values compared to the LVE animal rump.

  18. Collectivism and the meaning of suffering.

    2012-12-01

    People need to understand why an instance of suffering occurred and what purpose it might have. One widespread account of suffering is a repressive suffering construal (RSC): interpreting suffering as occurring because people deviate from social norms and as having the purpose of reinforcing the social order. Based on the theorizing of Emile Durkheim and others, we propose that RSC is associated with social morality-the belief that society dictates morality-and is encouraged by collectivist (as opposed to individualist) sentiments. Study 1 showed that dispositional collectivism predicts both social morality and RSC. Studies 2-4 showed that priming collectivist (vs. individualist) self-construal increases RSC of various types of suffering and that this effect is mediated by increased social morality (Study 4). Study 5 examined behavioral intentions, demonstrating that parents primed with a collectivist self-construal interpreted children's suffering more repressively and showed greater support for corporal punishment of children.

    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

    Full Text Available This study analyses characteristics of lung injuries produced by alveolar overdistension in three animal species. Mechanical ventilation at normal tidal volume (10 mL/Kg and high tidal volume (50 mL/Kg was applied for 30 min in each species. Data were gathered on wet/dry weight ratio, histological score, and area of alveolar collapse. Five out of six rabbits with high tidal volume developed tension pneumothorax, and the rabbit results were therefore not included in the histological analysis. Lungs from the pigs and rats showed minimal histological lesions. Pigs ventilated with high tidal volume had significantly greater oedema, higher neutrophil infiltration, and higher percentage area of alveolar collapse than rats ventilated with high tidal volume. We conclude that rabbits are not an appropriate species for in vivo studies of alveolar overdistension due to their fragility. Although some histological lesions are observed in pigs and rats, the lesions do not appear to be relevant.

    Colour vision in animals is an interesting, fascinating subject. In this study, we examined a wide variety of species for expression of S-opsin (blue sensitive) and M-/L-opsin (green-red sensitive) in retinal cones using two novel monoclonal antibodies specific for peptides from human opsins. Mouse, rat and hare did not express one of the investigated epitopes, but we could clearly prove existence of cones through peanut agglutinin labelling. Retinas of guinea pig, dog, wolf, marten, cat, roe deer, pig and horse were positive for S-opsin, but not for M-/L-opsin. Nevertheless all these species are clearly at least dichromats, because we could detect further S-opsin negative cones by labelling with cone arrestin specific antibody. In contrast, pheasant and char had M-/L-opsin positive cones, but no S-opsin expressing cones. Sheep, cattle, monkey, men, pigeon, duck and chicken were positive for both opsins. Visual acuity analyzed through density of retinal ganglion cells revealed least visual discrimination by horses and highest resolution in pheasant and pigeon. Most mammals studied are dichromats with visual perception similar to red-green blind people. PMID:23173557

    1999-01-01

    Full Text Available The basis for virulence in Paracoccidioides brasiliensis is not completely understood. There is a consensus that the sequencial in vitro subcultivation of P. brasiliensis leads to loss of its pathogenicity, which can be reverted by reisolation from animal passage. Attention to morphological and biochemical properties that are regained or demonstrated after animal passage may provide new insights into factors related to the pathogenicity and virulence of P. brasiliensis. We evaluated morphological characters: the percentage of budding cells, number of buds by cell and the diameter of 100 mother cells of yeast-like cells of 30 P. brasiliensis isolates, before and after animal passage. The isolates were obtained from patients with different clinical forms of paracoccidioidomycosis (PCM: acute form (group A, n=15 and chronic form (group C, n=15. The measurement of the yeast cell sizes was carried out with the aid of an Olympus CBB microscope coupled with a micrometer disc. We measured the major transverse and longitudinal axes of 100 viable cells of each preparation. The percentage of budding cells as also the number of buds by cell was not influenced by animal passage, regardless of the source of the strain (acute or chronic groups. The size values of P. brasiliensis isolates from groups A and C, measured before the animal passage exhibited the same behavior. After animal passage, there was a statistically significant difference between the cell sizes of P. brasiliensis isolates recovered from testicles inoculated with strains from groups A and C. The maximum diameter of mother cells from group A isolates exhibited a size of 42.1mm in contrast with 32.9mm exhibited by mother cells from group C (p<0.05. The diameter of 1500 mother cells from group A isolates exhibited a medium size of 16.0mm (SD ± 4.0, a value significantly higher than the 14.1mm (SD = ± 3.3 exhibited by 1500 mother cells from group C isolates (p<0.05.

    Full Text Available Despite the development of valuable new techniques (i.e. genetics, neuroimage for the study of the neurobiological substrate of psychiatric diseases, there are strong limitations in the information that can be gathered from human studies. It is thus critical to develop appropriate animal models of psychiatric diseases to characterize their putative biological bases and the development of new therapeutic strategies. The present review tries to offer a general perspective and several examples of how individual differences in animals can contribute to explain differential susceptibility to develop behavioural alterations, but also emphasizes methodological problems that can lead to inappropriate or over-simplistic interpretations. A critical analysis of the approaches currently used could contribute to obtain more reliable data and allow taking full advantage of new and sophisticated technologies. The discussion is mainly focused on anxiety-like and to a lower extent on depression-like behaviour in rodents.

    Infection and multiplication of Leishmania infantum and L. mexicana inside of skin fibroblasts from hamsters, mice and rats was achieved. This process was demonstrated either by counting parasites inside the stained cells or by electronic microscopy studies. In addition multiplication rate differences in the cells from these rodent species were determined, for L. infantum as well as for L. mexicana. Parasite development in hamsters and mice fibroblasts was evident but there was not multiplication in rat cells showing that apparently they are refractory to Leishmania infection. These results suggest that the parasite affinity for each animal, as well as any intracellular environment resistance, could involve genetic factors in the parasite multiplication. On the other hand, presence of amastigote multiplication inside of parasitophorus vacuole, showed by electronic microscopy images, probes a true parasite transformation. Therefore it is suggested that fibroblasts could work as host cells for parasite survival and permanency in the infected animals. PMID:17357424

The genuine SMB was prepared by following classical techniques of shodhana and marana most commonly used by different Ayurvedic drug manufacturers. Shodhana was done by roasting raw swarna makshika with lemon juice for three days and marana was performed by 11 putas . The experimental animals (rats were divided into two groups. SMB mixed with diluted honey was administered orally in therapeutic dose to Group SMB and diluted honey only was administered to vehicle control Group, for 30 days. The blood samples were collected twice, after 15 days and after 30 days of drug administration and different biochemical investigations were done. Biochemical parameters were chosen based on references from Ayurvedic classics and contemporary medicine. It was observed that Hb% was found significantly increased and LDL and VLDL were found significantly decreased in Group SMB when compared with vehicle control group. This experimental data will help the clinician for the logical use of SMB in different disease conditions with findings like low Hb% and high LDL, VLDL levels.

    The potential of using receptor-ligand dissociation rates as a model for investigating molecular changes in receptors was tested using the dissociation of [{sup 3}H]citalopram, [{sup 3}H]paroxetine and [{sup 3}H]imipramine from the brain 5-HT transporter of four different species (mouse, rat, pig and man). Since the dissociation rates of each of the three ligands differed in most of the species investigated, receptor-ligand dissociation rate constants would seem to be a sensitive measure of receptor conformation. The model could be useful in the search of structural variation in receptors whether attributable to genetic factors or to posttranslational modification. (au) (12 refs.).

  12. Animal welfare: neuro-cognitive approaches

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

  13. Late-phase MSCT in the different stages of myocardial infarction: animal experiments

    International Nuclear Information System (INIS)

    The purpose of this study was to intraindividually evaluate myocardial late enhancement on multislice spiral computed tomography (MSCT) for the assessment of the different stages of myocardial infarction (MI) in comparison with magnetic resonance (MR) imaging. Reperfused MI was successfully induced in seven pigs. Delayed enhancement MR imaging and late-phase MSCT were performed on day 0 as well as 7, 28 and 90 days after the procedure. The pigs were sacrificed, and 2,3,5-triphenyltetrazolin-chloride (TTC) staining was acquired. MI size was compared between the different imaging techniques and over time applying Bland-Altman plots and multivariate analysis with repeated measures. On day 0 the mean MI size was 23.7 ± 11.8% of the left ventricular area on MSCT and 24.5 ± 10.6% on MR imaging. On day 90 infarct sizes decreased significantly to 16.9 ± 8.4% and 18.9 ± 8.0%, respectively (P 0.0019). On TTC staining the size of MI was 16.8 ± 8.2%. Bland-Altman plots showed a good agreement between MSCT and MR imaging with mean deviations ranging from -3.4% to -1.9%. No significant difference between MSCT and MR imaging was found. Myocardial late enhancement on MSCT correlates well with delayed enhancement MR imaging during the different stages of MI and allows for reliable assessment of reperfused MI during acute, subacute and chronic stages.

    2016-01-01

    The dilemma so central to the work of providers of palliative and end-of-life care is the paradox of their professional and ethical duty to try to relieve suffering and the limitations of so doing. While the capacity to sit with suffering at the end of life is critical to clinical work, the idea that some intrinsic suffering cannot necessarily always be relieved may model for patients and families that suffering can be borne. Clinicians who encounter unrelievable suffering may feel a sense of failure, helplessness, moral distress, and compassion fatigue. While tolerating suffering runs counter to the aims of palliative care, acknowledging it, bearing it, and validating it may actually help patients and families to do the same. "Sitting with suffering" signals a paradigm shift within the discipline of palliative care, as it asks clinicians to rethink their role in being able to relieve some forms of psychosocial suffering intrinsic to dying.

  16. Suffering, justice, and the politics of becoming.

    Science.gov (United States)

    Connolly, W E

    1996-09-01

    To suffer is to undergo, to bear, to endure. Suffering exists on the underside of agency; it is as important to ethics as agency. The experience of suffering is never entirely captured by the ethical, political, medical and spiritual categories in which it is represented. Perhaps an engagement with suffering can open up hidden connections between these domains. After examining John Caputo and Friedrich Nietzsche comparatively on the relation between suffering and ethics, this essay explores the relation of the "politics of becoming" to suffering. The politics of becoming is a paradoxical process by which a new cultural identity is drawn into being and yet is irreducible to the energies and motives that spurred its initiators to action. To exemplify and think the politics of becoming is to call into question the sufficiency of existing paradigms of morality. A critical examination of the Rawlsian model of justice brings out, for example, the insufficiency of justice to the politics of becoming. It suggests the need, first, to pursue an "ethics of engagement" between several parties drawing upon a variety of sources of ethical inspiration and, second, to cultivate "critical responsiveness" to new social movements that struggle to place new identities onto the cultural register. If the latter movements sometimes modify general understandings of suffering, identity, justice and medical practice they also indicate the role cultural thinkers can play in re-examining periodically established codes of interaction between these domains.

  17. Anxiety from a Phylogenetic Perspective: Is there a Qualitative Difference between Human and Animal Anxiety?

    Full Text Available A phylogenetic approach to anxiety is proposed. The different facets of human anxiety and their presence at different levels of the phylum are examined. All organisms, including unicellular such as protozoan, can display a specific reaction to danger. The mechanisms enabling the appraisal of harmful stimuli are fully present in insects. In higher invertebrates, fear is associated with a specific physiological response. In mammals, anxiety is accompanied by specific cognitive responses. The expression of emotions diversifies in higher vertebrates, only primates displaying facial expressions. Finally, autonoetic consciousness, a feature essential for human anxiety, appears only in great apes. This evolutive feature parallels the progress in the complexity of the logistic systems supporting it (e.g., the vegetative and central nervous systems. The ability to assess one's coping potential, the diversification of the anxiety responses, and autonoetic consciousness seem relevant markers in a phylogenetic perspective.

    Meat is expensive to produce, making it is essential to understand the importance consumers pay to different meat cuts. Previous research on consumers' meat choices has mainly focused on meat species, while consumer preferences for meat cuts has so far only received limited interest. The aim of this study is to shed some light into this relatively unexplored area by answering four research questions. First, this study intends to show the relative importance meat cuts play in relation to other extrinsic product attributes. Secondly, this paper looks into differences in choice criteria between regular and special occasions. Third, consumer segments that differ in their preferences and beef purchase are identified, and, finally, the meat purchase portfolios of these segments are revealed. A stated preference methodology of a discrete choice experiment with cut-specific prices covering several meat cuts simultaneously is proposed to answer the research questions. The sample consists of 1500 respondents representative of the Italian population in terms of age, gender and geographic location The results shows that meat cut is the most important factor when choosing bovine meat followed by quality certification (origin), production technique, the type of breed and price. In terms of consumption occasions, we observe significantly lower price sensitivity for marbled steaks and cutlets for special occasions compared to normal occasions. Segmentation analysis shows that while the choices of two segments (comprising about 40% of the sample) are mostly driven by extrinsic product attributes, the remaining segments are mostly driven by meat cuts. These varying preferences are also reflected in the purchase portfolios of the different segments, while less variability is detected from a socio-demographic perspective. PMID:26363423

    Enhancing the quality of beef meat is an important goal in terms of improving both the nutritional value for the consumer and the commercial value for producers. The aim of this work was to study the effects of different vegetable oil supplements on growth performance, carcass quality and meat quality in beef steers reared under intensive conditions. A total of 240 Blonde D' Aquitaine steers (average BW=293.7±38.88 kg) were grouped into 24 batches (10 steers/batch) and were randomly assigned to one of the three dietary treatments (eight batches per treatment), each supplemented with either 4% hydrogenated palm oil (PALM) or fatty acids (FAs) from olive oil (OLI) or soybean oil (SOY). No differences in growth performance or carcass quality were observed. For the meat quality analysis, a steer was randomly selected from each batch and the 6th rib on the left half of the carcass was dissected. PALM meat had the highest percentage of 16:0 (PPALM. No significant differences in the sensory characteristics of the meat were noted. However, the results of the principal component analysis of meat characteristics enabled meat from those steers that consumed fatty acids from olive oil to be differentiated from that of steers that consumed soybean oil.

Secondly, we present and discuss five different kinds of views about...... the nature of our duties to animals. They are: contractarianism, utilitarianism, the animal rights view, contextual views, and a respect for nature view. Finally, we briefly consider whether it is possible to combine elements from the presented views, and how to make up one’s mind....

  1. Farmed fish welfare-suffering assessment and impact on product quality

    2010-01-01

    Full Text Available Fish welfare, suffering and the perception of pain were debated, together with several factors reducing infra vitam welfare of farmed fish (genetic, environment, density, malnutrition, starvation, cataracts, deformities, vaccination side effects, transport, handling, confinement, crowding, harvesting, killing method. Behavioural and physiological stress responses were considered as indicators of welfare reduction. The effects of pre-slaughter management practices, and the most commonly used stunning/slaughtering methods on welfare and quality reduction of farmed fish were discussed. A number of indicators can be used to assess fish welfare-suffering, both in a scientific and practical context, such as behavioural, haematic, cellular, tissue post mortem fish stress and quality indicators, but none of them are optimal. The best strategy for a reliable assessment of fish welfare/suffering and their impact on product quality is a multidisciplinary approach that takes into account animal behaviour and the different biochemical and physiological ante mortem and post mortem processes involved: several components, all influenced in a similar way by the same condition, suggest real welfare and quality reduction.

  2. The Nerve Supply of the Bone Marrow in Different Laboratory Animals

    International Nuclear Information System (INIS)

    The proliferation and release of the different types of cells from the bone marrow presents so many obscurities in the explanation of the maintenance of homeostasis at the level of the blood corpuscles that one wonders if this difficulty is due to a lack of information in some important area. The function of an organ, and the influence that other organs may have on its physiological and pathological changes, cannot be understood if the role of the nervous system and the hormones are not taken into consideration; but when we study the bone marrow and speak about its function as a blood-forming organ, the nervous system is continually ignored. The situation is such that the first question that comes to mind is this: Are there nerves in the bone marrow? The answer of the old anatomists was: Yes. The description of nerves entering into the bone cavity can be found in papers published more than one hundred years ago, but the description of their distribution and relation with the different elements of the marrow is vague and contradictory. Consequently we considered it worthwhile to study the problem of the innervation of the bone marrow anew

    Milk composition is an imperative aspect which influences the quality of dairy products. The objective of study was to compare the chemical composition, nitrogen fractions and amino acids profile of milk from buffalo, cow, sheep, goat, and camel. Sheep milk was found to be highest in fat (6.82%±0.04%), solid-not-fat (11.24%±0.02%), total solids (18.05%±0.05%), protein (5.15%±0.06%) and casein (3.87%±0.04%) contents followed by buffalo milk. Maximum whey proteins were observed in camel milk (0.80%±0.03%), buffalo (0.68%±0.02%) and sheep (0.66%±0.02%) milk. The non-protein-nitrogen contents varied from 0.33% to 0.62% among different milk species. The highest r-values were recorded for correlations between crude protein and casein in buffalo (r = 0.82), cow (r = 0.88), sheep (r = 0.86) and goat milk (r = 0.98). The caseins and whey proteins were also positively correlated with true proteins in all milk species. A favorable balance of branched-chain amino acids; leucine, isoleucine, and valine were found both in casein and whey proteins. Leucine content was highest in cow (108±2.3 mg/g), camel (96±2.2 mg/g) and buffalo (90±2.4 mg/g) milk caseins. Maximum concentrations of isoleucine, phenylalanine, and histidine were noticed in goat milk caseins. Glutamic acid and proline were dominant among non-essential amino acids. Conclusively, current exploration is important for milk processors to design nutritious and consistent quality end products. PMID:26954163

    Full Text Available Businesses and professions must stay in accord with social ethics, or risk losing their autonomy.A major social ethical issue that has emerged in the past four decades is the treatment of animals in various areas of human use. Society’s moral concern has outgrown the traditional ethic of animal cruelty that began in biblical times and is encoded in the laws of all civilized societies. There are five major reasons for this new social concern, most importantly, the replacement of husbandry-based agriculture with industrial agriculture. This loss of husbandry to industry has threatened the traditional fair contract between humans and animals, and resulted in significant amounts of animal suffering arising on four different fronts. Because such suffering is not occasioned by cruelty, a new ethic for animals was required to express social concerns. Since ethics proceed from preexisting ethics rather than ex nihilo, society has looked to its ethic for humans, appropriately modified, to find moral categories applicable to animals. This concept of legally encoded rights for animals has emerged as a plausible vehicle for reform.

    Understanding the internal structure of the proton is crucial challenge for QCD, and one important aspect of this is to understand how the spin of the nucleon is build-up from the angular momentum of its quarks and gluons. In this way, what's the origin of differences between angular momentums of fundamental particles? It may be from their substructures. It seems there are four sub-particles of mater, plant, animal and human in substructure of each fundamental particle (string) as the origins of life and cause of differences between spins of those elementary particles. Material's sub-particle always is on and active. When the environmental conditions became ready for creation of each field of the plant, animal and human, sub-particles of their elementary particles became on and active and then, those elementary particles participated in processes of creation in their own field. God, as the main source of information, has been communicated with their sub-particles and transfers a package (bit) of information and laws (plus standard ethics for human sub-particles) to each of them for process and selection (mutation) of the next step of motion and interaction of their fundamental particles with each other in each Plank's time. This is causality for particles' motion in quantum area.

  10. Change in the amount of epsilon-hexosyllysine, UV absorbance, and fluorescence of collagen with age in different animal species

    International Nuclear Information System (INIS)

    Skin and aorta collagen specimens of Wistar rats, white mice, beagle dogs, cats, horses, and human necropsies of different ages were examined with respect to the content of glycated products. The data presented show that (a) glycation and accumulation of the chromophore(s) are comparable in collagen samples from different species of comparable age; (b) glycation and pigmented accumulation increase markedly during the first 5-10 years of age; (c) the extent of glycation is different in different tissues (in particular, glycation of aortal collagen is about twice that of skin collagen); and (d) collagen pigmentation as followed by fluorescence is comparable in aortal and skin collagen (except below 10 years); pigmentation measured by absorbance at 350 nm is, on the contrary, lower in aortal than in skin collagen. Based on the assumption of constant blood glucose level during the life span, it appears feasible to conclude that the degree of nonenzymatic collagen glycation reflects the time period for which the protein was exposed to the action of sugars. This period, because of increased cross-linking, is likely to be extended in older animals. Other factors, such as differences in collagen turnover between different tissues and the intensity of the removal process of the glycated products, should be taken into consideration as well

    Full Text Available HIV-1 DNA vaccines have many advantageous features. Evaluation of HIV-1 vaccine candidates often starts in small animal models before macaque and human trials. Here, we selected and optimized DNA vaccine candidates through systematic testing in rabbits for the induction of broadly neutralizing antibodies (bNAb. We compared three different animal models: guinea pigs, rabbits and cynomolgus macaques. Envelope genes from the prototype isolate HIV-1 Bx08 and two elite neutralizers were included. Codon-optimized genes, encoded secreted gp140 or membrane bound gp150, were modified for expression of stabilized soluble trimer gene products, and delivered individually or mixed. Specific IgG after repeated i.d. inoculations with electroporation confirmed in vivo expression and immunogenicity. Evaluations of rabbits and guinea pigs displayed similar results. The superior DNA construct in rabbits was a trivalent mix of non-modified codon-optimized gp140 envelope genes. Despite NAb responses with some potency and breadth in guinea pigs and rabbits, the DNA vaccinated macaques displayed less bNAb activity. It was concluded that a trivalent mix of non-modified gp140 genes from rationally selected clinical isolates was, in this study, the best option to induce high and broad NAb in the rabbit model, but this optimization does not directly translate into similar responses in cynomolgus macaques.

  19. Pathological study on regularity of wound healing in rats irradiated with γ-rays before or after suffering trauma

    International Nuclear Information System (INIS)

    Objective: To study the different effects of radiation on wound healing in rats irradiated with γ rays before or after suffering trauma. Methods: Animal models of wound healing were set up, and they were locally irradiated before or after suffering trauma. The pathological changes were studied by gross and microscopic examinations. Immunohistochemistry and in situ hybridization were performed to detect the expression of collagen types I and III. Results: Wound healing was impaired and delayed obviously in rats locally irradiated with 15 Gy in the time period between 2 days before and 7 days after receiving trauma. The strongest effect was observed in rats irradiated immediately after trauma. Irradiation given on day 3 after trauma and day 2 before trauma resulted in moderate effects, while the least effect was noted in rats irradiated on day 7 after trauma. Conclusion: The effect of radiation on wound healing depends on the time of irradiation before or after receiving trauma

    The objective of this study was to investigate associations between genetic distance of porcine reproductive and respiratory syndrome virus (PRRSV) detected in Ontario swine herds, and the distance between the herds with respect to space, time, ownership and animal sources. PRRSV sequence data between September 2004 and August 2007 were obtained from the Animal Health Laboratory of the University of Guelph. Geographical coordinates were obtained from the Ontario Pork marketing board, and network information about ownership and animal suppliers was obtained using a telephone interview. The matrices of sequence, spatial, temporal and network distances were generated and were analysed using the Mantel test, and using linear-mixed models with P-values based on random permutations. A total of 438 PRRSV isolates from 329 premises and 232 ownerships were originally included; 57 of the isolates were considered vaccine type. The Mantel correlation test indicated that there was positive correlation between sequence distance and geographic distance (r = 0.11, P = 0.001), as well as sequence distance and temporal distance (r = 0.03, P = 0.03), with similar results reported after adjusting for the ownership distance. Mantel correlogram suggested existence of spatial correlation up to ~30 km distance. Multivariable linear-mixed model for association between genetic distance and space-time distance was characterized by the three-way interaction among space, time and ownership (P < 0.001). It suggested that positive association between sequence similarity and spatial proximity exists in herds under different ownerships, but its magnitude is very small. In contrast, for pairs of herds under identical ownership, the spatial association was more complex. This could be a consequence of interactions within ownerships, or alternatively decisions made about sampling of herds for diagnostic purposes. Of the networks evaluated, ownership (P < 0.001) and gilt supplier (P < 0

    Insects rely mainly on their well-developed and highly sophisticated olfactory system to discriminate volatile cues released from host and nonhost substances, mates, oviposition substrates, and food sources. Onset of first mating, mating duration, and onset of first oviposition, oviposition period, fecundity (number of eggs laid by a female), and longevity of freshly emerged Musca domestica L. (Diptera: Muscidae) adults were observed in the presence of different animal manures: cow, horse, donkey, poultry, and an artificial diet. The M. domestica adults exposed to horse manure showed a delay in onset of first mating and first oviposition, prolonged mating duration, and reduced fecundity compared to the artificial diet (control). Likewise, the fecundity was reduced in the presence of donkey manure as compared to artificial diet. The onset of first mating was delayed and duration of first mating was shortened in the presence of cow manure as compared to artificial diet and no oviposition was observed throughout the duration of the experiment. However, the reproductive behaviors and all fitness measures in adults exposed to poultry manure were similar or even better, compared to the artificial diet. Surprisingly, in a free-choice attraction assay, the highest numbers of adult flies were attracted toward the cow manure as compared to all other manures as well as the artificial diet. However, the numbers of flies captured in all other types of manures were not different than the artificial diet (control). Furthermore, chemical analysis of headspace samples of manures revealed qualitative differences in odor (volatile) profiles of all manures and artificial diet, indicating that behavioral differences could be due to the differences in the volatile chemistry of the adult ovipositional substrates and larval growth mediums. This study may contribute toward both understanding the linkage between ecological adaptations and host selection mechanisms and the development of

    Full Text Available Cnidarian-dinoflagellate symbioses are ecologically important and the subject of much investigation. However, our understanding of critical aspects of symbiosis physiology, such as the partitioning of total respiration between the host and symbiont, remains incomplete. Specifically, we know little about how the relationship between host and symbiont respiration varies between different holobionts (host-symbiont combinations. We applied molecular and biochemical techniques to investigate aerobic respiratory capacity in naturally symbiotic Exaiptasia pallida sea anemones, alongside animals infected with either homologous ITS2-type A4 Symbiodinium or a heterologous isolate of Symbiodinium minutum (ITS2-type B1. In naturally symbiotic anemones, host, symbiont, and total holobiont mitochondrial citrate synthase (CS enzyme activity, but not host mitochondrial copy number, were reliable predictors of holobiont respiration. There was a positive association between symbiont density and host CS specific activity (mg protein-1, and a negative correlation between host- and symbiont CS specific activities. Notably, partitioning of total CS activity between host and symbiont in this natural E. pallida population was significantly different to the host/symbiont biomass ratio. In re-infected anemones, we found significant between-holobiont differences in the CS specific activity of the algal symbionts. Furthermore, the relationship between the partitioning of total CS activity and the host/symbiont biomass ratio differed between holobionts. These data have broad implications for our understanding of cnidarian-algal symbiosis. Specifically, the long-held assumption of equivalency between symbiont/host biomass and respiration ratios can result in significant overestimation of symbiont respiration and potentially erroneous conclusions regarding the percentage of carbon translocated to the host. The interspecific variability in symbiont aerobic capacity provides

    Full Text Available For ex vivo measurements of fracture callus stiffness in small animals, different test methods, such as torsion or bending tests, are established. Each method provides advantages and disadvantages, and it is still debated which of those is most sensitive to experimental conditions (i.e. specimen alignment, directional dependency, asymmetric behavior. The aim of this study was to experimentally compare six different testing methods regarding their robustness against experimental errors. Therefore, standardized specimens were created by selective laser sintering (SLS, mimicking size, directional behavior, and embedding variations of respective rat long bone specimens. For the latter, five different geometries were created which show shifted or tilted specimen alignments. The mechanical tests included three-point bending, four-point bending, cantilever bending, axial compression, constrained torsion, and unconstrained torsion. All three different bending tests showed the same principal behavior. They were highly dependent on the rotational direction of the maximum fracture callus expansion relative to the loading direction (creating experimental errors of more than 60%, however small angular deviations (<15° were negligible. Differences in the experimental results between the bending tests originate in their respective location of maximal bending moment induction. Compared to four-point bending, three-point bending is easier to apply on small rat and mouse bones under realistic testing conditions and yields robust measurements, provided low variation of the callus shape among the tested specimens. Axial compressive testing was highly sensitive to embedding variations, and therefore cannot be recommended. Although it is experimentally difficult to realize, unconstrained torsion testing was found to be the most robust method, since it was independent of both rotational alignment and embedding uncertainties. Constrained torsional testing showed small

    Animal-based research presents an ethical dilemma between harms (to animals) and benefits (mainly to humans). According to Directive 2010/63/EU, project evaluation should include “a harm-benefit analysis of the project, to assess whether the harm to the animals in terms of suffering, pain and distress is justified by the expected outcome”. By defining benefit and its assessment very generally, legislation opens for a variety of interpretations. In this paper, we review different approaches, c...

    Meditation practices purportedly help people develop focused and sustained attention, cultivate feelings of compassionate concern for self and others, and strengthen motivation to help others who are in need. We examined the impact of 3 months of intensive meditative training on emotional responses to scenes of human suffering. Sixty participants were assigned randomly to either a 3-month intensive meditation retreat or a wait-list control group. Training consisted of daily practice in techniques designed to improve attention and enhance compassionate regard for others. Participants viewed film scenes depicting human suffering at pre- and posttraining laboratory assessments, during which both facial and subjective measures of emotion were collected. At post-assessment, training group participants were more likely than controls to show facial displays of sadness. Trainees also showed fewer facial displays of rejection emotions (anger, contempt, disgust). The groups did not differ on the likelihood or frequency of showing these emotions prior to training. Self-reported sympathy--but not sadness or distress--predicted sad behavior and inversely predicted displays of rejection emotions in trainees only. These results suggest that intensive meditation training encourages emotional responses to suffering characterized by enhanced sympathetic concern for, and reduced aversion to, the suffering of others.

  7. The moral aesthetics of simulated suffering in standardized patient performances.

    2011-06-01

    Standardized patient (SP) performances are staged clinical encounters between health-professional students and people who specialize in role-playing the part of patients. Such performances have in recent years become increasingly central to the teaching and assessment of clinical skills in U.S. medical schools. SP performances are valued for being both "real" (in that they involve interaction with a real person, unlike written examinations) and "not real" (in that the SP does not actually suffer from the condition portrayed, unlike an actual patient). This article considers how people involved in creating SP performances reconcile a moral commitment to avoid suffering (to keep it "not real"), with an aesthetic commitment to realistically portray it (to keep it "real"). The term "moral aesthetic" is proposed, to indicate a sensibility that combines ideas about what is morally right with ideas about what is aesthetically compelling. Drawing on ethnographic research among SPs and SP program staff and medical faculty who work closely with them, this article argues that their work of creating "realism" in simulated clinical encounters encompasses multiple different (and sometimes conflicting) understandings and practices of realism, informed by three different moral aesthetics: (1) a moral aesthetic of induction, in which an accurate portrayal with a well-documented provenance serves to introduce experientially distant forms of suffering; (2) a moral aesthetic of inoculation, in which the authenticity and emotional impact of a performance are meant to inoculate students against the impact of future encounters with suffering; (3) a moral aesthetic of presence, generating forms of voice and care that are born out of the embodied presence of suffering individuals in a clinical space. All are premised on the assumption that risk and suffering can be banished from SP performances. This article suggests, however, that SP performances necessarily raise the same difficult

  10. A Ploidy Difference Represents an Impassable Barrier for Hybridisation in Animals. Is There an Exception among Botiid Loaches (Teleostei: Botiidae)?

    One of the most efficient mechanisms to keep animal lineages separate is a difference in ploidy level (number of whole genome copies), since hybrid offspring from parents with different ploidy level are functionally sterile. In the freshwater fish family Botiidae, ploidy difference has been held responsible for the separation of its two subfamilies, the evolutionary tetraploid Botiinae and the diploid Leptobotiinae. Diploid and tetraploid species coexist in the upper Yangtze, the Pearl River and the Red River basins in China. Interestingly, the species 'Botia' zebra from the Pearl River basin combines a number of morphological characters that otherwise are found in the diploid genus Leptobotia with morphological characters of the tetraploid genus Sinibotia, therefore the aim of the present study is to test weather 'B.' zebra is the result of a hybridisation event between species from different subfamilies with different ploidy level. A closer morphological examination indeed demonstrates a high similarity of 'B.' zebra to two co-occurring species, the diploid Leptobotia guilinensis and the tetraploid Sinibotia pulchra. These two species thus could have been the potential parental species in case of a hybrid origin of 'B.' zebra. The morphologic analysis further reveals that 'B.' zebra bears even the diagnostic characters of the genera Leptobotia (Leptobotiinae) and Sinibotia (Botiinae). In contrast, a comparison of six allozyme loci between 'B.' zebra, L. guilinensis and S. pulchra showed only similarities between 'B.' zebra and S. pulchra, not between 'B.' zebra and L. guilinensis. Six specimens of 'B.' zebra that were cytogenetically analysed were tetraploid with 4n = 100. The composition of the karyotype (18% metacentric, 18% submetacentric, 36% subtelocentric and 28% acrocentric chromosomes) differs from those of L. guilinensis (12%, 24%, 20% and 44%) and S. pulchra (20%, 26%, 28% and 26%), and cannot be obtained by any combination of genomes from L

  11. Effects of simulated microgravity on surfactant and water balance of lung in animals with different resistance to stress

    Bryndina, Irina; Vasilieva, Natalia

    Weightlessness is accompanied by redistribution of blood flow in lung, changes of lung volumes and gas exchange (Prisk et al., 2002; Grigoriev, Baranov, 2003). On the other hand, it is known that microgravity is considered as a kind of moderate stress (Grigoriev et al., 2004). Stress response may differ in animals resistant or vulnerable to stress (Sudakov, 2007). To study the effects of simulated microgravity upon lung, we used 20 male albino rats tested for behavior in the "open field" and than divided into active (stress resistant - SR ) and passive (stress vulnerable - CV) groups. Two mouse lines were used with similar goal - C57Bl/6 and BALB/c mice (n=16). According to data obtained earlier, BALB/c mice referred as more stress vulnerable, in contrast to C57BL/6 mice, which are considered to be relatively stress resistant (Flint et al., 2007). We have previously shown that changes in lung surfactant system after psychosocial stress or long-term immobilization are less pronounced in stress resistant rats (Vasilieva, Bryndina, 2012). The aim of this work is to study the properties and biochemical composition of pulmonary surfactant and lung water balance in rats and mice with different stress resistance in antiorthostatic suspension (AOS) of short and long duration. Simulated microgravity was reproduced according to procedure of Ilyin-Novikov in modification of Morey-Holton. The duration of exposure was 10 days for rats and 30 days for mice. The properties of pulmonary surfactant were assessed by the evaluation of surface activity (surface tension - ST), the content of total phospholipids (PL) and their fractions. Simultaneously we calculated the gravimetric water balance indices: lung coefficient, "dry residue" and wet-to-dry ratio. Total and extravascular lung fluid and pulmonary blood supply were estimated as well. The experiments demonstrated that there was a decrease of surface tension of surfactant films after 10-day AOS in both groups of rats (to a greater

    Debate about the biological effects of biodiesel exhaust emissions exists due to variation in methods of exhaust generation and biological models used to assess responses. Because studies in cells do not necessarily reflect the integrated response of a whole animal, experiments were conducted in two human cell lines representing bronchial epithelial cells and macrophages and female mice using identical particle suspensions of raw exhaust generated by a Volkswagen light-duty diesel engine using petrodiesel (B0) and a biodiesel blend (B20: 20% soy biodiesel/80% B0 by volume). Tailpipe particle emissions measurement showed B0 generated two times more particle mass, larger ultrafine particle number distribution modes, and particles of more nonpolar organic composition than the B20 fuel. Biological assays (inflammatory mediators, oxidative stress biomarkers) demonstrated that particulate matter (PM) generated by combustion of the two fuels induced different responses in in vitro and in vivo models. Concentrations of inflammatory mediators (Interleukin-6, IL-6; Interferon-gamma-induced Protein 10, IP-10; Granulocyte-stimulating factor, G-CSF) in the medium of B20-treated cells and in bronchoalveolar lavage fluid of mice exposed to B20 were ∼20-30% higher than control or B0 PM, suggesting that addition of biodiesel to diesel fuels will reduce PM emissions but not necessarily adverse health outcomes.

    2010-01-01

    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.

    Incomplete information on toxicological differences of micro- and nanometer-sized particles raised concerns about the effects of the latter on health and environment. Besides chemical composition, size and surface-to-volume ratio of nanoparticles (NPs) can affect toxicity. To investigate size-dependent toxicity differences, we used particles made of dioxide of the neurotoxic heavy metal manganese (Mn), typically found in inhaled metal fumes, in three size ranges (size A, 9.14 ± 1.98 nm; size B, 42.36 ± 8.06 nm; size C, 118.31 ± 25.37 nm). For modeling the most frequent route of exposure to Mn, NPs were given to rats for 6 weeks by intratracheal instillation. Of each NP size, 3 or 6 mg/kg body weight was given while control animals were vehicle treated. Neurotoxicity was assessed by measuring spontaneous locomotor activity in an open field and by recording spontaneous and evoked electrical activity from the somatosensory cortical area. Mn content of brain, lung, and blood, measured by ICP-MS, were correlated to the observed functional alterations to see the relationship between Mn load and toxic effects. Body weight gain and organ weights were measured as general toxicological indices. The toxicity of size A and size B NPs proved to be stronger compared to size C NPs, seen most clearly in decreased body weight gain and altered spontaneous cortical activity, which were also well correlated to the internal Mn dose. Our results showed strong effect of size on NP toxicity, thus, beyond inappropriateness of toxicity data of micrometer-sized particles in evaluation of NP exposure, differentiation within the nano range may be necessary.

There is a consensus that the sequencial in vitro subcultivation of P. brasiliensis leads to loss of its pathogenicity, which can be reverted by reisolation from animal passage.

    BACKGROUND The use of hyaluronic acid (HA) for intra-articular (IA) injection is widespread around the world for patients affected by osteoarthritis. AIM The aim of this study is to identify scientific evidence from in vitro and in vivo studies supporting the use of IA HAs marketed in Italy. We also evaluated the accuracy of indications and contraindications reported in the leaflets of such HAs compared with the available scientific evidence. MATERIALS AND METHODS An extensive literature search was performed to identify all in vitro and in vivo model studies reporting on the effects of various HAs marketed in Italy for IA use. Data reported in the leaflets of different HA-based products for IA use were extracted and analyzed alongside evidence from in vitro and in vivo model studies. RESULTS Nine in vitro studies and 11 studies on animal models were examined. Comparing results with what is reported in the leaflets of HAs marketed in Italy, it was observed that many branded formulations are introduced in the market without any reporting of basic scientific evidence. Only 12.82% and 17.95% of branded products had been shown to be effective with scientific evidence from in vitro and in vivo studies, respectively. The rationale of use of these products is based on their nature, as if a class effect existed such that all HAs would yield similar effects. CONCLUSIONS Data on HAs deriving from in vitro and in vivo studies are scarce and relate to only a small percentage of products marketed in Italy. Many indications and contraindications are arbitrarily reported in Italian HA leaflets without the support of scientific evidence. Larger and brand-specific studies are necessary and should be reported in the leaflets to guide clinicians in making an appropriate choice regarding HA-based IA therapy. PMID:27257398

  20. Do lower vertebrates suffer from motion sickness?

    Science.gov (United States)

    Lychakov, Dmitri

    The poster presents literature data and results of the author’s studies with the goal to find out whether the lower animals are susceptible to motion sickness (Lychakov, 2012). In our studies, fish and amphibians were tested for 2 h and more by using a rotating device (f = 0.24 Hz, a _{centrifugal} = 0.144 g) and a parallel swing (f = 0.2 Hz, a _{horizontal} = 0.059 g). The performed studies did not revealed in 4 fish species and in toads any characteristic reactions of the motion sickness (sopite syndrome, prodromal preparatory behavior, vomiting). At the same time, in toads there appeared characteristic stress reactions (escape response, an increase of the number of urinations, inhibition of appetite), as well as some other reactions not associated with motion sickness (regular head movements, eye retractions). In trout fry the used stimulation promoted division of the individuals into the groups differing by locomotor reaction to stress, as well as the individuals with the well-expressed compensatory reaction that we called the otolithotropic reaction. Analysis of results obtained by other authors confirms our conclusions. Thus, the lower vertebrates, unlike mammals, are immune to motion sickness either under the land conditions or under conditions of weightlessness. On the basis of available experimental data and theoretical concepts of mechanisms of development the motion sickness, formulated in several hypotheses (mismatch hypothesis, Traisman‘ s hypothesis, resonance hypothesis), there presented the synthetic hypothesis of motion sickness that has the conceptual significance. According to the hypothesis, the unusual stimulation producing sensor-motor or sensor-sensor conflict or an action of vestibular and visual stimuli of frequency of about 0.2 Hz is perceived by CNS as poisoning and causes the corresponding reactions. The motion sickness actually is a byproduct of technical evolution. It is suggested that in the lower vertebrates, unlike mammals

    This study evaluated the effects of different doses of atropine and new antiepileptics, levetiracetam and topiramate, on the development of convulsions triggered by food intake in antimuscarinic-treated fasted animals. Mice deprived of food for 24 h and treated i.p. with atropine at a dose of 2.4 or 24 mg/kg developed convulsions after being allowed to eat ad libitum. No convulsions were observed in fasted animals treated with 0.24 mg/kg atropine. There was no difference in the incidence of convulsions between the two atropine treatments, but latency to convulsions was longer in 24 mg/kg atropine treated animals. The lowest dose of atropine, 0.24 mg/kg, caused stage 1 and stage 2 activity, but did not provide the convulsive endpoint (stage 3, 4, 5 activity). Administration of levetiracetam (50 or 200 mg/kg) or topiramate (50 or 100 mg/kg) to another group of 24-h fasted mice was ineffective in reducing the incidence of convulsions developed in the animals after 2.4 mg/kg atropine treatment and food intake. However, the higher dose of levetiracetam prolonged the onset of convulsions. Present results demonstrated the efficacy of low and high doses of atropine on the development of convulsions in fasted animals and provided additional evidence for the ineffectiveness of antiepileptic treatment in these seizures.

    Full Text Available The current study aims to assess the effect from crude glycerin inclusion (0, 7, 14, and 21% dry matter in the diet of slaughtered lamb on their development, nutrient consumption, biometrical measures, diet economic viability and carcass features. Thirty two (32 non-castrated male Texel lambs were used in the study, they presented mean initial weight 15.9 ± 4.1 kilos and were distributed in casual outlining. They were fed with four treatments, with 8 repetitions. Animals were slaughtered when they reached approximately 35 kilos. The mean total weight gain was 20.72 kilos and mean daily weight gain was 260 grams. No changes resulted from glycerin use. The carcass performance was similar among treatments (P>0.05 and the cold carcass performance (CCP was 44.68%. There were no effects (P>0.05 on the loin eye area (LEA and on fat thickness (FT; they showed averages of 13.66 cm2 and 0.84 mm, respectively. Nutrition cost per animal during the whole confinement period varied between R$82.60 (eighty-two Reais and forty-eight cents to R$92.48. The smallest nutrition amount consisted of 21% crude glycerin. The gross profit ranged from R$30.75 to R$ 34.01 per animal, for feed without glycerin and 21% glycerin, respectively. Animal development was not impacted by glycerin introduction, even with decrease on dry and organic mass consumption. The result showed that crude glycerin inclusion might be used in lambs’ diet. Whenever there are big amounts of feed involved in the process, the 21% crude glycerin addition may be an interesting cost reduction. Seventy eight percent (78% glycerol crude glycerin to replace corn-based feed in confined lambs’ diet appeared to be nutritionally and economically viable.

    Citizens' concerns about farm animal welfare are often dismissed on the assumption that they are not well informed about farming practices. We conducted exploratory surveys of interested citizens (n = 50) before and after a self-guided tour of a 500-head dairy farm. 'Before' survey questions explored perceptions, concerns, and values about dairy cattle farming and welfare, in addition to a short knowledge-based quiz on dairy cattle husbandry. An 'after' survey explored the extent to which these constructs shifted after the tour. Before, most participants correctly answered quiz questions about general feeding and housing practices, but scores were low on questions about specific practices such as cow-calf separation. Participants considered several elements as necessary for a 'good' life for dairy cattle: fresh food and water, pasture access, gentle handling, space, shelter, hygiene, fresh air and sunshine, social companions, absence of stress, health, and safety from predators. These elements reflect a diverse conception of animal welfare that incorporates values for physical and mental well-being, natural living, and humane care. The visit had a mixed effect on perceptions of whether dairy cows had a 'good' life, improving perceptions for a quarter of participants, worsening perceptions in a third, with no shift in the remaining participants. The visit appeared to mitigate some concerns (e.g., provision of adequate food and water, gentle humane care) while reinforcing or eliciting others (e.g., lack of pasture access, early cow-calf separation). Moreover, animal welfare-relevant values held by participants (e.g., natural living, care) appeared to play an important role in influencing perceptions of farm practices. These results suggest that education and exposure to livestock farming may resolve certain concerns, but other concerns will likely persist, especially when practices conflict with deeply held values around animal care.

    Interdisciplinarity is the combined care of a patient by two or more healthcare professionals. Taking into account the contribution of the different healthcare partners improves patient follow-up, quality of the care and use of resources. General practitioner (GP) becomes the pivot of a combined interdisciplinary ambulatory care allowing a prolonged staying at home and avoiding the multiplication of care offers. This paper, by the clinical description of a patient suffering from Diogenes Syndrome, allows a cross of the care between the GP, home nurse and pharmacist. It deals with follow-up questions, acceptance, objectives of treatment, communication between healthcare partners and "false notes" in the follow-up. PMID:25055477

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

    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.

    Salmonella enterica and Escherichia coli can inhabit humans and animals from multiple origins. These bacteria are often associated with gastroenteritis in animals, being a frequent cause of resistant zoonotic infections. In fact, bacteria from animals can be transmitted to humans through the food chain and direct contact. In this study, we aimed to assess the antibiotic susceptibility of a collection of S. enterica and E. coli recovered from animals of different sources, performing a genomic comparison of the plasmid-mediated quinolone resistance (PMQR)-producing isolates detected. Antibiotic susceptibility testing revealed a high number of non-wild-type isolates for fluoroquinolones among S. enterica recovered from poultry isolates. In turn, the frequency of non-wild-type E. coli to nalidixic acid and ciprofloxacin was higher in food-producing animals than in companion or zoo animals. Globally, we detected two qnrS1 and two aac(6′)-Ib-cr in E. coli isolates recovered from animals of different origins. The genomic characterization of QnrS1-producing E. coli showed high genomic similarity (O86:H12 and ST2297), although they have been recovered from a healthy turtle dove from a Zoo Park, and from a dog showing symptoms of infection. The qnrS1 gene was encoded in a IncN plasmid, also carrying blaTEM−1−containing Tn3. Isolates harboring aac(6′)-Ib-cr were detected in two captive bottlenose dolphins, within a time span of two years. The additional antibiotic resistance genes of the two aac(6′)-Ib-cr-positive isolates (blaOXA−1, blaTEM−1,blaCTX−M−15, catB3, aac(3)-IIa, and tetA) were enclosed in IncFIA plasmids that differed in a single transposase and 60 single nucleotide variants. The isolates could be assigned to the same genetic sublineage—ST131 fimH30-Rx (O25:H4), confirming clonal spread. PMQR-producing isolates were associated with symptomatic and asymptomatic hosts, which highlight the aptitude of E. coli to act as silent vehicles, allowing

  3. Endurance of animals and man in short-term period after standard radiation action in different doses

    International Nuclear Information System (INIS)

    Values of the average lethal doses (LD 50) for various species of animals (mice, rats, hamsters, rabbits, pigs, sheep, goats, dogs, monkeys) were analyzed on the basis of the numerous experimental studies to extrapolate values of LD 50 as applied to a human being. It was shown that when the affected hemopoiesis systems was the main cause od death of animals, all large biological; species were characterized by high radiation sensitivity and by LD lou-values within 155-260 s Gy limits, while small ones turned to be rather radiation resistant ones. Guinea pigs and monkeys were the exceptions to that classification. However, it was not possible to obtain rather exact LD evaluation for a human being on the basis of extrapolation. More exact values of the absorbed doses were obtained in the course of therapeutic irradiation of patients, but those results might be used for healthy persons with the additional correction. All the presented data might be used to evaluate radiation hazard of an astronaut

  4. Animal and vegetal pole cells of early Xenopus embryos respond differently to maternal dorsal determinants: implications for the patterning of the organiser

    International Nuclear Information System (INIS)

    The maternal dorsal determinants required for the specification of the dorsal territories of Xenopus early gastrulae are located at the vegetal pole of unfertilised eggs and are moved towards the prospective dorsal region of the fertilised egg during cortical rotation. While the molecular identity of the determinants is unknown, there are dorsal factors in the vegetal cortical cytoplasm (VCC). Here, we show that the VCC factors, when injected into animal cells activate the zygotic genes Siamois and Xnr3, suggesting that they act along the Wnt/β-catenin pathways. In addition, Siamois and Xnr3 are activated and at the vegetal pole of UV-irradiated embryos, indicating that these two genes are targets of the VCC factors in all embyronic cells. However, the consequences of their activation in cells that occupy different positions along the animal-vegetal axis differ. Dorsal vegetal cells of normal embryos or VCC-treated injected animal cells are able to dorsalise ventral mesoderm in conjugate experiments but UV-treated vegetal caps do not have this property. We propose that the regionalisation of the organiser during gastrulation proceeds from the differential interpretation along the animal-vegetal axis of the activation of the VCC/β-catenin/Siamois pathway.

    Simple Summary When making a choice of species for animal experimentation we must balance its suitability as a model for human medicine against the potential harms to the animals both from the procedures and the quality of their lifetime experience. The capacity to experience pain may be similar in mammals, birds and fish. The capacity to suffer from fear is governed more by sentience than cognitive ability, so it cannot be assumed that rodents or farm animals suffer less than dogs or primate...

    Background COPD is one of the leading causes of morbidity and mortality in both high- and low-income countries and a major public health burden worldwide. While cigarette smoking remains the main cause of COPD, outdoor and indoor air pollution are important risk factors to its etiology. Although studies over the last 30 years helped reduce the values, it is not very clear if the current air quality guidelines are adequately protective for COPD sufferers. Objective This systematic review was to summarize the up-to-date literature on the impact of air pollution on the COPD sufferers. Methods PubMed and Google Scholar were utilized to search for articles related to our study’s focus. Search terms included “COPD exacerbation”, “air pollution”, “air quality guidelines”, “air quality standards”, “COPD morbidity and mortality”, “chronic bronchitis”, and “air pollution control” separately and in combination. We focused on articles from 1990 to 2015. We also used articles prior to 1990 if they contained relevant information. We focused on articles written in English or with an English abstract. We also used the articles in the reference lists of the identified articles. Results Both short-term and long-term exposures to outdoor air pollution around the world are associated with the mortality and morbidity of COPD sufferers even at levels below the current air quality guidelines. Biomass cooking in low-income countries was clearly associated with COPD morbidity in adult nonsmoking females. Conclusion There is a need to continue to improve the air quality guidelines. A range of intervention measures could be selected at different levels based on countries’ socioeconomic conditions to reduce the air pollution exposure and COPD burden. PMID:27143874

    Males are predominantly affected by autism spectrum disorders (ASD) with a prevalence ratio of 5:1. However, the underlying pathological mechanisms governing the male preponderance of ASD remain unclear. Recent studies suggested that epigenetic aberrations may cause synaptic dysfunctions, which might be related to the pathophysiology of ASD. In this study, we used rat offspring prenatally exposed to valproic acid (VPA) as an animal model of ASD. We found male-selective abnormalities in the kinetic profile of the excitatory glutamatergic synaptic protein expressions linked to N-methyl-D-aspartate receptor (NMDAR), alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) and metabotropic glutamate receptor 5 (mGluR5) pathways in the prefrontal cortex of the VPA-exposed offspring at postnatal weeks 1, 2, and 4. Furthermore, VPA exposure showed a male-specific attenuation of the methyl-CpG-binding protein 2 (MeCP2) expressions both in the prefrontal cortex of offspring and in the gender-isolated neural progenitor cells (NPCs). In the gender-isolated NPCs culture, higher concentration of VPA induced an increased glutamatergic synaptic development along with decreased MeCP2 expression in both genders suggesting the role of MeCP2 in the modulation of synaptic development. In the small interfering RNA (siRNA) knock-down study, 50 pmol of Mecp2 siRNA inhibited the MeCP2 expression in male- but not in female-derived NPCs with concomitant induction of postsynaptic proteins such as PSD95. Taken together, we suggest that the male-inclined reduction of MeCP2 expression is involved in the abnormal development of glutamatergic synapse and male preponderance in the VPA animal models of ASD.

    The prevention and relief of suffering has long been a core medical concern. But while this is a laudable goal, some question whether medicine can, or should, aim for a world without pain, sadness, anxiety, despair or uncertainty. To explore these issues, we invited experts from six of the world's major faith traditions to address the following question. Is there value in suffering? And is something lost in the prevention and/or relief of suffering? While each of the perspectives provided maintains that suffering should be alleviated and that medicine's proper role is to prevent and relieve suffering by ethical means, it is also apparent that questions regarding the meaning and value of suffering are beyond the realm of medicine. These perspectives suggest that medicine and bioethics have much to gain from respectful consideration of religious discourse surrounding suffering. PMID:25680422

    Hay fever is a pollen-induced allergic reaction that strongly affects the overall quality of life of many individuals. The disorder may vary in severity and symptoms depending on patient-specific factors such as genetic disposition, individual threshold of pollen concentration levels, medication, former immunotherapy, and others. Thus, information services that improve the quality of life of hay fever sufferers must address the needs of each individual separately. In this paper, we demonstrate the development of information services that offer personalized pollen-induced symptoms forecasts. The backbone of these services consists of data of allergic symptoms reported by the users of the Personal Hay Fever Diary system and pollen concentration levels (European Aeroallergen Network) in several sampling sites. Data were analyzed using computational intelligence methods, resulting in highly customizable forecasting models that offer personalized warnings to users of the Patient Hay Fever Diary system. The overall system performance for the pilot area (Vienna and Lower Austria) reached a correlation coefficient of r = 0.71 ± 0.17 (average ± standard deviation) in a sample of 219 users with major contribution to the Pollen Hay Fever Diary system and an overall performance of r = 0.66 ± 0.18 in a second sample of 393 users, with minor contribution to the system. These findings provide an example of combining data from different sources using advanced data engineering in order to develop innovative e-health services with the capacity to provide more direct and personalized information to allergic rhinitis sufferers.

  14. Recognition and assessment of pain in animals

    Full Text Available Pain is a complex physiological phenomenon, it is hard to define in a satisfactory manner in human beings, and it is extremely difficult to recognize and interpret in animals. According to the International Association for the Study of Pain (IASP, pain is defined as an unpleasant sensory or emotional experience associated with actual or potential tissue damage. Pain is an important aspect of life and its prevention and decrease are important as a goal to achieve the well-being of animals. The task of scientists is to recognize the language of pain interpretation which animals use to seek help. For an objective evaluation of pain, it is essential to possess a good knowledge of physiology, etiology and clinical diagnosis. We are obliged to do this also because of the ethic principles to defend the well-being of animals and to eliminate any factor which can cause feelings of pain or suffering. The recognition of pain and its manifestation is especially important in cases of animal abuse, when it could be the only symptom. Animals can be quiet and instinctively hide the presence of pain, which makes the symptoms more subtle, but does not make their injuries any less painful. It is also important to have knowledge of manifestations of pain that appear during different surgical procedures performed by the veterinarinarian in spite of the applied dose of analgetic. Pain significantly contributes to the suffering of animals and in such cases it is important to collect relevant documents, in the form of video recordings or in photodocumentation form, because it is important information in the processing of cases of animal abuse. Veterinary experts have the responsibility to recognize, evaluate, and prevent pain and to relieve animals from the pain, which should be the fourth vital sign, following temperature, pulse and breathing, and participate in the evaluation of the condition of the animal during an examination. Due to all the above mentioned, it is

    Background Bone cancer pain is often severe, yet little is known about mechanisms generating this type of chronic pain. While previous studies have identified functional alterations in peripheral sensory neurons that correlate with bone tumours, none has provided direct evidence correlating behavioural nociceptive responses with properties of sensory neurons in an intact bone cancer model. Results In a rat model of prostate cancer-induced bone pain, we confirmed tactile hypersensitivity using the von Frey test. Subsequently, we recorded intracellularly from dorsal root ganglion neurons in vivo in anesthetized animals. Neurons remained connected to their peripheral receptive terminals and were classified on the basis of action potential properties, responses to dorsal root stimulation, and to mechanical stimulation of the respective peripheral receptive fields. Neurons included C-, Aδ-, and Aβ-fibre nociceptors, identified by their expression of substance P. We suggest that bone tumour may induce phenotypic changes in peripheral nociceptors and that these could contribute to bone cancer pain. Conclusions This work represents a significant technical and conceptual advance in the study of peripheral nociceptor functions in the development of cancer-induced bone pain. This is the first study to report that changes in sensitivity and excitability of dorsal root ganglion primary afferents directly correspond to mechanical allodynia and hyperalgesia behaviours following prostate cancer cell injection into the femur of rats. Furthermore, our unique combination of techniques has allowed us to follow, in a single neuron, mechanical pain-related behaviours, electrophysiological changes in action potential properties, and dorsal root substance P expression. These data provide a more complete understanding of this unique pain state at the cellular level that may allow for future development of mechanism-based treatments for cancer-induced bone pain.

    Despite the vast amount of studies focusing on bone nanostructure that have been performed for several decades, doubts regarding the detailed structure of the constituting hydroxyapatite crystal still exist. Different experimental techniques report somewhat different sizes and locations, possibly due to different requirements for the sample preparation. In this study, small- and wide-angle X-ray scattering is used to investigate the nanostructure of femur samples from young adult ovine, bovine, porcine, and murine cortical bone, including three different orthogonal directions relative to the long axis of the bone. The radially averaged scattering from all samples reveals a remarkable similarity in the entire q range, which indicates that the nanostructure is essentially the same in all species. Small differences in the data from different directions confirm that the crystals are elongated in the [001] direction and that this direction is parallel to the long axis of the bone. A model consisting of thin plates is successfully employed to describe the scattering and extract the plate thicknesses, which are found to be in the range of 20-40 Å for most samples but 40-60 Å for the cow samples. It is demonstrated that the mineral plates have a large degree of polydispersity in plate thickness. Additionally, and equally importantly, the scattering data and the model are critically evaluated in terms of model uncertainties and overall information content. PMID:26914607

    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.

    To effectively manage surface and ground waters it is necessary to improve our ability to detect and identify sources of fecal contamination. We evaluated the use of the anaerobic bacterial group Bacteroides-Prevotella as a potential fecal indicator. Terminal restriction length polymorphism (T-RFLP) of the 16S rRNA genes from this group was used to determine differences in populations and to identify any unique populations in chickens, cows, deer, dogs, geese, horses, humans, pigs, and seagulls. The group appears to be a good potential fecal indicator in all groups tested except for avians. Cluster analysis of Bacteroides-Prevotella community T-RFLP profiles indicates that Bacteroides-Prevotella populations from samples of the same host species are much more similar to each other than to samples from different source species. We were unable to identify unique peaks that were exclusive to any source species; however, for most host species, at least one T-RFLP peak was identified to be more commonly found in that species, and a combination of peaks could be used to identify the source. T-RFLP profiles obtained from water spiked with known-source feces contained the expected diagnostic peaks from the source. These results indicate that the approach of identifying Bacteroides-Prevotella molecular markers associated with host species might be useful in identifying sources of fecal contamination in the environment.

  7. Suffering caused by care—Patients’ experiences from hospital settings

    Full Text Available Suffering and well-being are significant aspects of human existence; in particular, suffering and well-being are important aspects of patients’ experiences following diseases. Increased knowledge about existential dimensions of illness and healthcare experiences may be needed in order to improve care and reduce unnecessary suffering. Therefore, the aim of this paper is to illuminate the phenomenon of suffering experienced in relation to healthcare needs among patients in hospital settings in Sweden. In this study, we used a reflective lifeworld approach. The data were analysed with a focus on meanings. The results describe the essential meaning of the phenomenon of suffering in relation to healthcare needs. The patients were suffering during care-giving when they felt distrusted or mistreated and when their perspective on illness and health was overlooked. Suffering was found to arise due to healthcare actions that neglected a holistic and patient-centred approach to care. Unfortunately, healthcare experiences that cause patients to suffer seem to be something one needs to endure without being critical. The phenomenon can be described as having four constituents: to be mistreated; to struggle for one's healthcare needs and autonomy; to feel powerless; and to feel fragmented and objectified. The study concludes that there are problems associated with patients experiencing suffering at the hands of healthcare providers, even if this suffering may not have been caused deliberately to the patient. Consequently, conscious improvements are needed to lessen the suffering caused by care-giving, as are strategies that promote more patient-centred care and patient participation.

    A field study was conducted to investigate the effect of vaccination against porcine circovirus type 2 (PCV2) in pigs suffering from porcine respiratory disease complex (PRDC). A total of 1542 pigs were allocated randomly into two treatment groups at approximately 20 days of age. Groups received either a Baculovirus-expressed recombinant PCV2 Open Reading Frame (ORF) 2 vaccine or placebo by single intramuscular injection. Median onset of PCV2 viraemia and respiratory signs occurred when animals were 18 weeks old. Vaccination reduced the mean PCV2 viral load by 55-83% (p < 0.0001) and the mean duration of viraemia by 50% (p < 0.0001). During the period of study (from 3 to 25 weeks of age) vaccinated animals exhibited a reduced mortality rate (6.63% vs. 8.67%, difference -2.04%; p = 0.1507), an improved average daily weight gain (649 g/day vs. 667 g/day; difference +18 g/day; p < 0.0001) and a reduced time to market (164.8 days vs. 170.4 days; difference -5.6 days; p < 0.0001). The effects on performance were greatest in the 8-week period between the onset of PCV2 viraemia and the end of finishing. These data demonstrate that vaccination against PCV2 alone can significantly improve the overall growth performance of pigs in a multi-factorial, late occurring disease complex such as PRDC.

    Full Text Available Background: The objective of the following study is to determine and to compare the different morphological parameters with duration of obstruction created experimentally in unilateral upper ureters of rats. Materials and Methods: Unilateral upper ureteric obstruction was created in 60 adult Wistar rats that were reversed after predetermined intervals. Rats were sacrificed and ipsilateral kidneys were subjected for analysis of morphological parameters such as renal height, cranio-caudal diameter, antero-posterior diameter, lateral diameter, volume of the pelvis and average cortical thickness: Renal height. Results: Renal height and cranio-caudal diameter of renal pelvis after ipsilateral upper ureteric obstruction started rising as early as 7 days of creating obstruction and were affected earlier than antero-posterior and lateral diameter and also were reversed earlier than other parameters after reversal of obstruction. Renal cortical thickness and volume of the pelvis were affected after prolonged obstruction (> 3 weeks and were the late parameters to be reversed after reversal of obstruction. Conclusions: Cranio-caudal diameter and renal height were the early morphological parameters to be affected and reversed after reversal of obstruction in experimentally created ipsilateral upper ureteric obstruction.

    Curcumin, the active ingredient of the spice turmeric, has a long history as an herbal remedy for a variety of diseases. Transdermal drug delivery has been recognized as an alternative route to oral delivery. Proniosomes offer a versatile vesicle delivery concept with the potential for drug delivery via the transdermal route. In this study, different proniosomal gel bases were prepared by the ether injection method, using Span 60 and Span 80, Tween 20, cholesterol, and formulation PA2. They were characterized by scanning electron microscopy, revealing vesicular structures, and assessed for stability and effect on in vitro skin permeation using rat skin. Anti-inflammatory and anti-arthritic effects of formulation PA2 and PB1 were compared with a standard market product containing indomethacin. The effect of formulation PA2 and PB1 was evaluated for acute inflammation in carrageenan induced rat paw edema and for chronic inflammation in complete Freud's adjuvant (CFA) induced arthritis in rats. Further histopathological and radiographic evaluation was performed. The investigated curcumin loaded proniosomal formula proved to be non-irritant, non-toxic, but had lower anti-inflammatory and anti-arthritic effects than the marketed indomethacin products.

    Full Text Available The objective of this study was to assess spiritual needs of patients with fibromyalgia syndrome (FMS and to evaluate correlations with disease and health associated variables. Using a set of standardized questionnaires (i.e., Spiritual Needs Questionnaire, Fibromyalgia Impact Questionnaire, SF-36's Quality of Life, Brief Multidimensional Life Satisfaction Scale, etc., we enrolled 141 patients (95% women, mean age 58 ± 10 years. Here, needs for inner peace and giving/generativity scored the highest, while existential needs and religious needs scored lowest. Particularly inner peace needs and existential needs correlated with different domains of reduced mental health, particularly with anxiety, the intention to escape from illness, and psychosocial restrictions. Thirty-eight percent of the patients stated needs to be forgiven and nearly half to forgive someone from their past life. Therefore, the specific spiritual needs of patients with chronic diseases should be addressed in clinical care in order to identify potential therapeutic avenues to support and stabilize their psychoemotional situation.

    Full Text Available Abstract Background Phospholipid hydroperoxide glutathione peroxidases (PHGPx, the most abundant isoforms of GPx families, interfere directly with hydroperoxidation of lipids. Biochemical properties of these proteins vary along with their donor organisms, which has complicated the phylogenetic classification of diverse PHGPx-like proteins. Despite efforts for comprehensive analyses, the evolutionary aspects of GPx genes in invertebrates remain largely unknown. Results We isolated GPx homologs via in silico screening of genomic and/or expressed sequence tag databases of eukaryotic organisms including protostomian species. Genes showing strong similarity to the mammalian PHGPx genes were commonly found in all genomes examined. GPx3- and GPx7-like genes were additionally detected from nematodes and platyhelminths, respectively. The overall distribution of the PHGPx-like proteins with different biochemical properties was biased across taxa; selenium- and glutathione (GSH-dependent proteins were exclusively detected in platyhelminth and deuterostomian species, whereas selenium-independent and thioredoxin (Trx-dependent enzymes were isolated in the other taxa. In comparison of genomic organization, the GSH-dependent PHGPx genes showed a conserved architectural pattern, while their Trx-dependent counterparts displayed complex exon-intron structures. A codon for the resolving Cys engaged in reductant binding was found to be substituted in a series of genes. Selection pressure to maintain the selenocysteine codon in GSH-dependent genes also appeared to be relaxed during their evolution. With the dichotomized fashion in genomic organizations, a highly polytomic topology of their phylogenetic trees implied that the GPx genes have multiple evolutionary intermediate forms. Conclusion Comparative analysis of invertebrate GPx genes provides informative evidence to support the modular pathways of GPx evolution, which have been accompanied with sporadic

  1. 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.

    Full Text Available Since the Criminal law of the Republic of Serbia in 2005 as well as the Law on veterinary medicine, there has been an increasing number of cases that deal with raising criminal charges due to animal killing or torturing. There is also a significant number of forensic cases that are aimed at discovering criminal acts. Animal abuse is a social issue, which includes a range of behaviors of humans that are harmful to animals, starting from unintentional neglect to intentional cruelty. Types of animal abuse are different and they can include physical, sexual, emotional abuse, or neglect. Abuse and neglect of animals have a variety of forms and manifestations, but the end result is always the same - animal suffering. The connection between animal abuse, domestic violence, and child abuse indicates that there is a significant role of veterinarians in social contexts and in terms of stopping this vicious cycle by preventing, discovering and turning in suspects involved in these crimes. The help that veterinarians provide to public prosecutors is of great importance. This study shows the role of veterinarians in cases of possible animal abuse, as well as their role in processing that type of cases.

    Full Text Available Mineralized tissues accumulate elements that play crucial roles in animal health. Although elemental content of bone, blood and teeth of human and some animal species have been characterized, data for many others are lacking, as well as species comparisons. Here we describe the distribution of elements in horn (Bovidae, antler (Cervidae, teeth and bone (humerus across a number of species determined by handheld X-ray fluorescence (XRF to better understand differences and potential biological relevance. A difference in elemental profiles between horns and antlers was observed, possibly due to the outer layer of horns being comprised of keratin, whereas antlers are true bone. Species differences in tissue elemental content may be intrinsic, but also related to feeding habits that contribute to mineral accumulation, particularly for toxic heavy metals. One significant finding was a higher level of iron (Fe in the humerus bone of elephants compared to other species. This may be an adaptation of the hematopoietic system by distributing Fe throughout the bone rather than the marrow, as elephant humerus lacks a marrow cavity. We also conducted discriminant analysis and found XRF was capable of distinguishing samples from different species, with humerus bone being the best source for species discrimination. For example, we found a 79.2% correct prediction and success rate of 80% for classification between human and non-human humerus bone. These findings show that handheld XRF can serve as an effective tool for the biological study of elemental composition in mineralized tissue samples and may have a forensic application.

  13. Suffering caused by care—elderly patients’ experiences in community care

    Directory of Open Access Journals (Sweden)

    Rune Svanström

    2013-11-01

    Full Text Available Background: Growing old involves many changes in life and implies an increased risks of illness and different forms of disabilities. Life may change in a radical way when a person gets a disease like dementia or moves to a nursing home due to disabilities or needs. In both cases, it often leads to an increased dependency on care where the patient becomes exposed and vulnerable and thereby at a higher risk for experiencing different forms of suffering. Aim: The aim of this study was to elucidate and gain a deeper understanding of elderly patients’ experiences of suffering in relation to community care in nursing homes and home care services. Materials and methods: A lifeworld hermeneutical approach was used. Phenomenological interviews and conversations with an open approach were conducted and analysed with a focus on meanings. Findings: The findings were presented in four main themes; an absence of the other in care, an absence of dialogues, a sense of alienation and a sense of insecurity. The findings in this study revealed that persons who were cared for in nursing homes and home care services sometimes were exposed to an unnecessary suffering. The suffering sometimes was caused by various caring actions, that is, unnecessary suffering. The suffering caused by care that aroused was due to caregiver's inability to be present, to show their face, and truly meet the patient. Conclusion: Suffering from care increased the elderly patients’ feelings of insecurity, loneliness, and alienation; this seemed to be the foundation for patients’ experiences of being outside a human community. There was a lack of knowledge and understanding about the patient's lifeworld.

    Patients in forensic psychiatric settings not only have to deal with their mental illness, but also memories of criminal activities and being involuntarily hospitalized. The aim of the present study was to explore how nurses working in forensic psychiatric services understand and approach patients' experiences of suffering. Data were generated by semistructured interviews with psychiatric nurses from two different forensic psychiatric units in Sweden. Data were analysed by means of a hermeneutic approach inspired by Ricoeur's hermeneutics. The findings are reflected in four main themes: (i) ignoring suffering; (ii) explaining suffering as a natural and inevitable part of daily life in the forensic context; (iii) ascribing meaning to suffering; and, (iv) being present in suffering. To engage in alleviating suffering is a struggle that demands courage and the strength to reflect on its character and consequences. To encounter suffering means that nurses are not only confronted with patients' suffering, but also their own reactions to those patients. If suffering is not recognized or encountered, there is a risk that actions may have a negative impact on patients. PMID:25639292

    Full Text Available The objective of the present study was to evaluate the response of rats suffering from moderate renal insufficiency to bacterial lipopolysaccharide (LPS, or endotoxin. The study involved 48 eight-week-old male SPF Wistar rats (175-220 g divided into two groups of 24 animals each. One group underwent 5/6 nephrectomy while the other was sham-operated. Two weeks after surgery, the animals were further divided into two subgroups of 12 animals each and were fasted for 20 h but with access to water ad libitum. One nephrectomized and one sham-treated subgroup received E. coli LPS (25 µg/kg, iv while the other received a sterile, pyrogen-free saline solution. Gastric retention (GR was determined 10 min after the orogastric infusion of a standard saline test meal labeled with phenol red (6 mg/dl. The gastric emptying of the saline test meal was studied after 2 h. Renal function was evaluated by measuring the plasma levels of urea and creatinine. The levels of urea and creatinine in 5/6 nephrectomized animals were two-fold higher than those observed in the sham-operated rats. Although renal insufficiency did not change gastric emptying (median %GR = 26.6 for the nephrectomized subgroup and 29.3 for the sham subgroup, LPS significantly retarded the gastric emptying of the sham and nephretomized groups (median %GR = 42.0 and 61.0, respectively, and was significantly greater (P<0.01 in the nephrectomized rats. We conclude that gastric emptying in animals suffering from moderate renal insufficiency is more sensitive to the action of LPS than in sham animals

  3. Iodine metabolism and thyroid functions in various species of domestic animals and poultry birds. I - Species difference in thyroid status as reflected by triiodothyronine 131I uptake test

    International Nuclear Information System (INIS)

    In vitro triiodothyronine-131I uptake, by red blood cells was studied in buffaloes, buffaloe calves, cross-bred calves, rams, goats, piglets and also in pure white leg horn and cross-bred birds. Results revealed that buffalo calves have the lowest uptake values, whereas piglets appeared to have the highest values as compared to other species. Distinct differences in the uptake of T3-131I by the erythrocytes were observed to exist within as well as amongst the species of farm animals and poultry birds studied. Cross-breds exhibited higher degree of T3-131I uptake as compared to pure-breds. This test offers promise where more tedious methods may not be possible for conducting the survey on the thyroid status and iodine metabolism on large population of live-stock. (author)

    A case of animal sexual abuse and sadism in a female sheep is described. The animal suffered severe genital tract injury most likely caused by the insertion and manipulation of a branch of wood and by penile penetration by a human male. Postmortem examination revealed multiple perforations of the vagina with massive haemorrhages. Animal sexual abuse is a complex diagnostic problem in veterinary medicine. Reported cases are often linked to sadism and often lead to the animal's death. Veterinarians should keep in mind animal sexual abuse as a differential diagnosis in cases of anogenital injuries of unknown origin. PMID:18848792

    The social niche specialization hypothesis predicts that animal personalities emerge as a result of individuals occupying different social niches within a group. Here we track individual personality and performance and collective performance among groups of social spiders where we manipulated the familiarity of the group members. We show that individual personalities, as measured by consistent individual differences in boldness behavior, strengthen with increasing familiarity and that these personalities can be disrupted by a change in group membership. Changing group membership negatively impacted both individual and group performance. Individuals in less familiar groups lost weight, and these groups were less successful at performing vital collective tasks. These results provide a mechanism for the evolution of stable social groups by demonstrating that social niche reestablishment carries a steep cost for both individuals and groups. Social niche specialization may therefore provide a potential first step on the path toward more organized social systems. PMID:27172596

    2013-10-01

    The development of pluripotent cells that enable stem cell research (SCR) without destroying human embryos is now a leading priority for science. Public and political controversies associated with human embryonic SCR experienced in the recent past should be alleviated if scientists no longer need to harvest cells from human embryos. This research suggests however additional issues needing attention in order to gain the public's trust and support: the use of mouse embryos and the commercialisation of research. Using a representative sample of 2,800 Australians, and an experimental telephone survey design, this research compared levels and predictors of public support for stem cell research across three cell source conditions: human embryo (HE), mouse embryo (ME) and induced pluripotent cells (iPSCs). The results revealed that the public were significantly more likely to support research using iPSCs than HE and ME cells and public compared to private research (regardless of the cell source). There was no significant difference in support for HE compared to ME research, but the former was viewed as more likely to lead to accessible health care benefits and to be associated with more trustworthy scientists. The results of a multimediation structural equation model showed that the primary reason support for SCR significantly dropped in a private compared to public context (i.e., the commercialisation effect) was because public scientists were trusted more than private scientists. This effect was consistent across all three SCR materials, suggesting that the use of mouse embryos or even iPSCs will not reduce the publics' concern with commercialised science. The implications these results have for public acceptance of stem cell and animal research are discussed in relation to possible solutions such as increasing public awareness of the regulation of animal research and benefit sharing.

    The aim of the study is to discuss and problematise notions of femininity and masculinity constructed in teaching situations among 16-year-old upper-secondary students studying science. The empirical examples originate from a teaching session with the theme of `sex and relationships'. The analysis is focused on metaphors inherent in a lesson that has its origins in the animal world. The findings show that the lesson `sex in the animal world' is full of anthropomorphism, metaphors that humanise animal behaviour. Teachers and students compare the animals' sexual behaviour with human behaviour, with the result that the animal world can be perceived as representative of natural sexual behaviour. The survey illustrates problems with how the examples are permeated by cultural values in the presentation of the animal world and how these examples form constructions of femininity and masculinity in the classroom.

It adopts a Razian conception of rights, whereby an individual possesses a right if an interest of that individual is sufficient to impose a duty on another. To ascertain whether animals have a right not to be experimented on, three interests are examined which might found such a right: the interest in not suffering, the interest in staying alive, and the interest in being free.

    Full Text Available This article seeks to explore the mystical approaches to suffering characteristic of both Buddhism and Christianity. Through the analysis of the meanings, the two traditions in question ascribe to suffering as a ‘component’ of mystical experience; it challenges the somewhat oversimplified understanding of the dichotomy ’sage-the-robot versus saint-the-sufferer’. Thus it contributes to the ongoing discussion on the theological–spiritual dimensions of the human predicament, as interpreted by various religious traditions. It also illustrates (though only implicitly in what sense – to use the Kantian distinction – the mystical experience offers boundaries (Schranken without imposing limits (Grenzen to interfaith encounter and dialogue. Man [sic] is ready and willing to shoulder any suffering, as soon and as long as he can see a meaning in it. (Frankl 1967:56

    Full Text Available Abstract Background Since 1994, Brucella strains have been isolated from a wide range of marine mammals. They are currently recognized as two new Brucella species, B. pinnipedialis for the pinniped isolates and B. ceti for the cetacean isolates in agreement with host preference and specific phenotypic and molecular markers. In order to investigate the genetic relationships within the marine mammal Brucella isolates and with reference to terrestrial mammal Brucella isolates, we applied in this study the Multiple Loci VNTR (Variable Number of Tandem Repeats Analysis (MLVA approach. A previously published assay comprising 16 loci (MLVA-16 that has been shown to be highly relevant and efficient for typing and clustering Brucella strains from animal and human origin was used. Results 294 marine mammal Brucella strains collected in European waters from 173 animals and a human isolate from New Zealand presumably from marine origin were investigated by MLVA-16. Marine mammal Brucella isolates were shown to be different from the recognized terrestrial mammal Brucella species and biovars and corresponded to 3 major related groups, one specific of the B. ceti strains, one of the B. pinnipedialis strains and the last composed of the human isolate. In the B. ceti group, 3 subclusters were identified, distinguishing a cluster of dolphin, minke whale and porpoise isolates and two clusters mostly composed of dolphin isolates. These results were in accordance with published analyses using other phenotypic or molecular approaches, or different panels of VNTR loci. The B. pinnipedialis group could be similarly subdivided in 3 subclusters, one composed exclusively of isolates from hooded seals (Cystophora cristata and the two others comprising other seal species isolates. Conclusion The clustering analysis of a large collection of marine mammal Brucella isolates from European waters significantly strengthens the current view of the population structure of these two

    Full Text Available Aims: Alcohol hangover is a poorly understood cluster of symptoms occurring following a heavy consumption of alcohol. The term "delayed alcohol-induced headache" is often used synonymously. Our objective was to compare alcohol hangover symptoms in migraine sufferers and nonsufferers. Materials and Methods: In this cross-sectional study, university students were asked to fill structured questionnaires assessing headache history, alcoholic consumption, and hangover symptoms (using the Hangover Symptom Scale (HSS. Subjects were classified as suffering from migraine with or without aura and nonsufferers according the International Classification of Headache Disorders 2 nd Edition (ICHD-II. The 13 hangover symptoms were divided by the researches into migraine-like and other nonmigraine-like symptoms. Results: Hangover symptoms among 95 migraine sufferers and 597 nonsufferers were compared. Migraine sufferers consumed less alcohol compared with the nonsufferers (mean drinks/week 2.34 ± 4.11 vs. 2.92 ± 3.58, P = 0.038 and suffered from higher tendency to migraine-like symptoms after drinking (mean 2.91 ± 3.43 vs. 1.85 ± 2.35, P = 0.002 but not to other hangover symptoms (mean 5.39 ± 6.31 vs. 4.34 ± 4.56, P = 0.1. Conclusions: Migraine sufferers consume less alcohol, especially beer and liquors, and are more vulnerable to migraine-like hangover symptoms than nonsufferers. The finding that the tendency to develop migraine attacks affects the hangover symptomatology may suggest a similarity in pathophysiology, and possibly in treatment options.

    The ubiquitous Sarcoptes mite is unexplainable emerging and re-emerging parasite, threatening biodiversity and human health. When a new outbreak occurs, it is not clear if it is a genuine emergence resulting from a new incidence or apparent emergence resulting from increased detection. In this paper we report, for the first time to our knowledge, an outbreak of sarcoptic mange in giraffes in the wild. Three decaying carcasses and five free-ranging subadult reticulated giraffes were observed to have mange-like lesions in the drought-suffering Wajir Region in North Eastern Kenya, while apparently all sympatric wild and domestic animals were mange-free. Affected giraffes were captured and successfully treated. The possible relations between this outbreak and annual seasons, animal age-classes and sex, and spatial distribution are discussed.

    This study potentiates the adsorbent effect for aflatoxin B1 (AFB1) of a commercial additive (CA) of animal feed, containing inactive lysate of three Saccharomyces cerevisiae strains, active enzymes, adsorbents and a selenium-amino acid complex, when the additive was mixed separately with three S. cerevisiae strains. Levels of AFB1 of 20 and 50 ng g(-1) were used to determine the binding capacity of different concentrations of CA alone and in the presence of yeast strains, as well as toxin desorption, under gastrointestinal conditions. The viability of yeasts in the presence of CA was evaluated. The results show that the CA did not affect the viability of the yeast strains assayed. CA alone showed a low percentage adsorption. At 20 and at 50 ng g(-1), CA was highly efficient in adsorbing AFB1 when combined with RC016 and RC012 strains respectively. Desorption of AFB1 by CA alone and in combination with the yeasts increased with increasing levels of CA. The results demonstrate the improvement of CA in AFB1 adsorption once it is mixed with live yeasts. PMID:25941951

    Caregivers' nutrition knowledge and attitudes may influence the variety of foods available in the household and the quality of children's diets. To test the link, this study collected data on caregivers' (n 608) nutrition knowledge and feeding attitudes as well as the diets of their household and of their 2-5-year-old children in twelve rural communities nested in the three main agro-ecological zones of Ghana. Household foods and children's animal source foods (ASF) consumed in the past 7 d were categorised into one of fourteen and ten groups, respectively. About 28 % of caregivers believed that their children needed to be fed only 2-3 times/d. Reasons for having adult supervision during child meal times, feeding diverse foods, prioritising a child to receive ASF and the perceived child benefits of ASF differed across zones (Pcaregivers belonging to the highest tertile of nutrition knowledge and attitude scores consumed more diverse diets compared with those of caregivers in the lowest tertile group (11·2 (sd 2·2) v. 10·0 (sd 2·4); Pcaregivers' nutrition knowledge and feeding attitudes positively predicted household dietary diversity and the frequency and diversity of children's ASF intakes (Pcaregivers also positively predicted household dietary diversity and children's ASF diversity (Pchild nutrition is to understand the context-specific nutrition knowledge and feeding attitudes in order to identify relevant interventions.

  15. Sociable Weavers Increase Cooperative Nest Construction after Suffering Aggression

    Leighton, Gavin M.; Meiden, Laura Vander

    2016-01-01

    The major transitions in evolution rely on the formation of stable groups that are composed of previously independent units, and the stability of these groups requires both cooperation and reduced conflict. Conflict over group resources may be common, as suggested by work in both cichlids and humans that has investigated how societies resolve conflict regarding investment in group resources, i.e. public goods. We investigated whether sociable weavers (Philetairus socius) use aggressive behaviors to modulate the cooperative behavior of group mates. We find that the individuals that build the communal thatch of the nest, i.e. the individuals most at risk of exploitation, are the most aggressive individuals. We show that individuals that invest in interior chamber maintenance, possibly a more selfish behavior, suffer relatively more aggression. After suffering aggression individuals significantly increase cooperative construction of the communal nest thatch. We show that cooperative individuals target aggression towards selfish individuals, and the individuals suffering aggression perform cooperative behaviors subsequent to suffering aggression. In addition to other evolutionary mechanisms, these results suggest that aggression, possibly via the pay-to-stay mechanism, is possibly being used to maintain a public good. PMID:26982704

    T and FINS in serum. Glucometer was used to test FPG. Local morphological structure of ovary was observed through light microscope after HE coloration. Results: Compared with group A(the control group), the density of FSH、FINS and T increased in group B(induced by Letrozole) and the difference was of statistical significance(P<0.05). Compared with group A, the density of LH in serum of group B increased significantly and the difference was of great statistical significance(P<0.05). Compared with group C (the control group), the densities of LH and E2 of group D(induced by silastic capsule of levonorgestrel subdermal together with HCG) increased and the difference was of statistical significance(P<0.05). Compared with group C, the density of T of group D increased significantly and the difference was of great statistical significance(P<0.05). Group E (induced by dehydroepiandrosterone) failed during the experiment and was deleted. In Group A and C, the local morphological structure of the ovaries were normal and mature follicles and dominant follicle could be seen while in group B and D, no dominant follicles could be seen and polycystic ovaries could be seen. Conclusion: In terms of the influence on serum hormones, FPG and FINS or the local morphological changes of the ovary, the rats models with PCOS and IR induced by Letrozole or silastic capsule of levonorgestrel subdermal together with HCG show similar symptoms as those in the clinic. So these methods meet the requirement of making animal models with PCOS and IR.

    Full Text Available Abstract Background Although sleep disorders are common, they frequently remain unnoticed by the general practitioner. Few data are available about the willingness and reasons of patients with sleep disturbances to seek for medical assistance. Methods The results of a cross-sectional community-based multinational survey in three major Latin American urban areas, i.e. Buenos Aires, Mexico City and Sao Paulo, are reported. Two-hundred subjects suffering sleep disturbances and 100 non-sufferers were selected from the general population in each city (total number: 600 sufferers vs. 300 non-sufferers. A structured interview was conducted, sleep characteristics, feelings about sleep disturbances and strategies to cope with those problems being recorded. Data were analyzed by employing either t-test or analysis of variance (ANOVA to the Z-transformed proportions. Results 22.7 ± 3.5 % (mean ± SEM of subjects reported to suffer from sleep disturbances every night. About 3 out of 4 (74.2 ± 2.0 % considered their disorder as mild and were not very concerned about it. Only 31 ± 2 % of sufferers reported to have sought for medical help. Although 45 ± 2 % of sufferers reported frequent daily sleepiness, trouble to remember things, irritability and headaches, they did not seek for medical assistance. Among those patients who saw a physician with complaints different from sleep difficulties only 1 out of 3 (33 ± 2 % of patients were asked about quality of their sleep by the incumbent practitioner. Strategies of patients to cope with sleep problems included specific behaviors (taking a warm bath, reading or watching TV (44 ± 1.6 %, taking herbal beverages (17 ± 1.2 % or taking sleeping pills (10 ± 1.1 %.

  19. Ethics and images of suffering bodies in humanitarian medicine.

    Science.gov (United States)

    Calain, Philippe

    2013-12-01

    Media representations of suffering bodies from medical humanitarian organisations raise ethical questions, which deserve critical attention for at least three reasons. Firstly, there is a normative vacuum at the intersection of medical ethics, humanitarian ethics and the ethics of photojournalism. Secondly, the perpetuation of stereotypes of illness, famine or disasters, and their political derivations are a source of moral criticism, to which humanitarian medicine is not immune. Thirdly, accidental encounters between members of the health professions and members of the press in the humanitarian arena can result in misunderstandings and moral tension. From an ethics perspective the problem can be specified and better understood through two successive stages of reasoning. Firstly, by applying criteria of medical ethics to the concrete example of an advertising poster from a medical humanitarian organisation, I observe that media representations of suffering bodies would generally not meet ethical standards commonly applied in medical practice. Secondly, I try to identify what overriding humanitarian imperatives could outweigh such reservations. The possibility of action and the expression of moral outrage are two relevant humanitarian values which can further be spelt out through a semantic analysis of 'témoignage' (testimony). While the exact balance between the opposing sets of considerations (medical ethics and humanitarian perspectives) is difficult to appraise, awareness of all values at stake is an important initial standpoint for ethical deliberations of media representations of suffering bodies. Future pragmatic approaches to the issue should include: exploring ethical values endorsed by photojournalism, questioning current social norms about the display of suffering, collecting empirical data from past or potential victims of disasters in diverse cultural settings, and developing new canons with more creative or less problematic representations of

    Contact allergies are complex diseases, and it is estimated that 15-20 % of the general population suffers from contact allergy, with increasing prevalence. Evaluation of the sensitization potential of a substance is usually carried out in animal models. Nowadays, there is much interest in reducing and ultimately replacing current animal tests. Furthermore, as of 2013, the EU has posed a ban on animal testing of cosmetic ingredients that includes skin sensitization. Therefore, predictive and robust in vitro tests are urgently needed. In order to establish alternatives to animal testing, the in vitro tests must mimic the very complex interactions between the sensitizing chemical and the different parts of the immune system. This review article summarizes recent efforts to develop in vitro tests for predicting skin sensitizers. Cell-based assays, in chemico methods and, to a lesser extent, in silico methods are presented together with a discussion of their current status. With considerable progress having been achieved during the last years, the rationale today is that data from different non-animal test methods will have to be combined in order to obtain reliable hazard and potency information on potential skin sensitizers.

    Twenty years after the 1994 genocide, Rwanda shows all indications of moving quickly towards socio-economic prosperity. Rwanda's community justice system, Gacaca, was to complement this prosperity by establishing peace and stability through justice, reconciliation and healing. Evaluations of the Gacaca courts' achievements from 2002 to 2012 have had widely differing conclusions. This article adds to previous evaluations by drawing attention to specific forms of relatively neglected suffering (in literature and public space) that have emerged from the Gacaca courts or were amplified by these courts and jeopardize Gacaca's objectives. The ethnographic study that informs the article was conducted in southeastern Rwanda from September 2008-December 2012 among 19 ex-prisoners and 24 women with husbands in prison including their family members, friends and neighbors. Study findings suggest that large scale imprisonment of genocide suspects coupled with Gacaca court proceedings have tainted the suffering of ex-prisoners and women with imprisoned husbands in unique ways, which makes their plight unparalleled in other countries. We argue that the nature and scale of this suffering and the potentially detrimental impact on families and communities require humanitarian action. However, in Rwanda's post-genocide reality, the suffering of these two groups is overwhelmed by that of other vulnerable groups, such as genocide survivors and orphaned children; hence it is rarely acknowledged.

    The purpose of this research synthesis was to describe the essence of the spiritual dimension reflected through the horizon of suffering. The material reviewed consisted of 18 articles published between 1989 and 2000 in caring and nursing journals. A depth in the interpretation of the texts was discovered where four different themes emerged: undemanding communion, confirmation of dignity, the dialectic of suffering, and the creation of coherence of meaning.

  9. 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].

  14. Engendering social suffering: a Chinese diasporic community in northern Thailand.

    Science.gov (United States)

    Huang, Shu-Min

    2014-01-01

    This paper examines how reproducing Chineseness has become a source of social suffering through the case study of a group of Yunnan Chinese who escaped Chinese communist rules in the Mainland in 1949 or shortly after and settled in northern Thailand in the 1960s. As self-proclaimed carriers of traditional Chinese culture, they worked arduously to replicate whatever they considered 'authentic' Chinese through a narrow interpretation of the Confucian moral tenets in daily life. The (re)establishment of a patriarchal social order in Thailand - a society with a relatively high level of gender-equality, has inflicted tremendous pain and suffering among women and youth in this reified society. Ethnographic fieldwork, upon which this paper was based, was conducted in Maehong Village, Chiang Mai Province, between 2002 and 2007. PMID:24559201

    Larsson, Ricard; Engström, Åsa

    2013-04-01

    Effective pre-hospital treatment of a person suffering cardiac arrest is a challenging task for the ambulance nurses. The aim of this study was to describe ambulance nurses' experiences of nursing patients suffering cardiac arrest. Qualitative personal interviews were conducted during 2011 in Sweden with seven ambulance nurses with experience of nursing patients suffering cardiac arrests. The interview texts were analyzed using qualitative thematic content analysis, which resulted in the formulation of one theme with six categories. Mutual preparation, regular training and education were important factors in the nursing of patients suffering cardiac arrest. Ambulance nurses are placed in ethically demanding situations regarding if and for how long they should continue cardio-pulmonary resuscitation (CPR) to accord with pre-hospital cardiac guidelines and patients' wishes. When a cardiac arrest patient is nursed their relatives also need the attention of ambulance nurses. Reflection is one way for ambulance nurses to learn from, and talk about, their experiences. This study provides knowledge of ambulance nurses' experiences in the care of people with cardiac arrest. Better feedback about the care given by the ambulance nurses, and about the diagnosis and nursing care the patients received after they were admitted to the hospital are suggested as improvements that would allow ambulance nurses to learn more from their experience. Further development and research concerning the technical equipment might improve the situation for both the ambulance nurses and the patients. Ambulance nurses need regularly training and education to be prepared for saving people's lives and also to be able to make the right decisions. PMID:23577977

    Full Text Available Schizophrenia, a psychiatric illness is a 4th leading cause of disability among adults. It is estimated to affect 1% of the general population. Aim of the present study was to conduct epidemiological survey of patients suffering of schizophrenia in Gujarat. This retrospective study was conducted on patients visiting Santvan Hospital Nadiad,Gujarat. Data were collected by the case report forms and analyzed for age, sex, symptoms of schizophrenic patients and prescribed drugs. Male and female patients (n=55 with age > 15 years and 50 years were excluded from this study. Analysis of the data revealed that females and males affecting schizophrenia were almost equal. This disease appeared earlier in men usually in early twenties than in women who were affected in the twenties to early thirties. Female patients were suffered from irritable mood more than males. Male patients suffered from apathetic mood more than females. All cases studied were had negative symptoms of schizophrenia. Polypharmacy was observed in drug prescription as on an average drugs prescribed per patient was 3 to 4. Olanzapine (98% was most prescribed drug followed by clozapine (64%, lorazepam (64%, escitalopram (50% and risperidone (32%.

    邓永芳; 胡文娟

    2012-01-01

    探究孟子动物伦理思想,可得出其主要观点有:动物在人类社会中的地位决定于人类生存、发展的需要;是否经过道德教化是动物与人的区别所在;对待动物的态度是爱护,但无需上升到“仁”“德”和“亲”“爱”的高度;宰杀动物需要讲求不忍之心,而君子远庖厨是一种仁术;动物保护和管理对于环境具有经济、美学上的价值等。庄子和孟子的动物伦理思想具有较大的差异性,其中庄子借动物阐述自己的自由理想,可以看做是一种动物伦理的元哲学;而孟子借动物阐述自己的政治理想,可以看做是一种动物政治伦理学。%The main points of Mencius' animal ethics are: the status of animals in human society depends on the needs of human survival and development; differences between human and animal lie in moral cultivation; the attitude towards animals should be to protect, and there is no need to rise to the height of benevolence and love; a man of noble character should keep away from animal killing; protection of animals can bring economic and aesthetic value to the environment; etc. There are great differences in animal ethics between Zhuangzi and Mencius in that Zhuangzi explained his view of freedom through description of animals, which can be thought of as the meta-philosophy of animal ethics while Mencius used description of animals to explain his political view which can be thought of as a kind of animal political ethics.

    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.

    De Backer, Charlotte J S; Hudders, Liselot

    2015-01-01

    The aim of this work is to explore the relation between morality and diet choice by investigating how animal and human welfare attitudes and donation behaviors can predict a meat eating versus flexitarian versus vegetarian diet. The results of a survey study (N=299) show that animal health concerns (measured by the Animal Attitude Scale) can predict diet choice. Vegetarians are most concerned, while full-time meat eaters are least concerned, and the contrast between flexitarians and vegetarians is greater than the contrast between flexitarians and full-time meat eaters. With regards to human welfare (measured by the Moral Foundations Questionnaire), results show that attitudes towards human suffering set flexitarians apart from vegetarians and attitudes towards authority and respect distinguish between flexitarians and meat eaters. To conclude, results show that vegetarians donate more often to animal oriented charities than flexitarians and meat eaters, while no differences between the three diet groups occur for donations to human oriented charities.

    As travellers seek ever more exotic destinations they are more likely to encounter dangerous animals. Compared to risks such as AIDS, traffic accidents and malaria, the risk is not so great; many travellers are, however, concerned about this and those who give pre-travel vaccines and advice should know something about it. This article is mainly based on medical and zoological textbooks. Venomous stings and bites may be prevented by adequate clothing and by keeping safe distance to the animals. Listening to those who live in the area is of course important. Travellers should not carry antisera with them, but antisera should be available at local hospitals. It should be borne in mind that plant eaters cause just as many deaths as large predators. In some cases it is necessary to carry a sufficiently powerful firearm. PMID:12555616

    Sometimes the relaxation after stress may trigger a migraine attack. This is the principle that underlies that particular variant of migraine called "weekend headache". We hypothesize the presence in weekend headache prone subjects of a particular psychological background, different from that of common migraine sufferers. In order to detect possible differences supporting our hypothesis, we studied 104 new outpatients: 46 patients suffering from headache only on weekends (23 males and 23 females) and 58 matched common migraineurs (26 males and 32 females) with no weekend predilection. The psychological assessment was performed using the following psychometric tools: MMPI, BDI, STAIX1-X2. A clinical assessment of each patient was also carried out. Significant differences were found after statistically analyzing the test results. Most of the MMPI scales were found to be more elevated in both male and female weekend headache sufferers. From a clinical point of view, the weekend headache attacks proved to be similar to those of common migraine, but with a significantly higher incidence of concomitant symptoms. Our study confirms the important role that psychological factors play in the pathogenesis and clinical development of migraine and leads us to conclude that a psychic tension component is associated with the vascular one in weekend headache.

  18. Anaesthesia for positron emission tomography scanning of animal brains.

    Science.gov (United States)

    Alstrup, Aage Kristian Olsen; Smith, Donald F

    2013-01-01

    Positron emission tomography (PET) provides a means of studying physiological and pharmacological processes as they occur in the living brain. Mice, rats, dogs, cats, pigs and non-human primates are often used in studies using PET. They are commonly anaesthetized with ketamine, propofol or isoflurane in order to prevent them from moving during the imaging procedure. The use of anaesthesia in PET studies suffers, however, from the drawback of possibly altering central neuromolecular mechanisms. As a result, PET findings obtained in anaesthetized animals may fail to correctly represent normal properties of the awake brain. Here, we review findings of PET studies carried out either in both awake and anaesthetized animals or in animals given at least two different anaesthetics. Such studies provide a means of estimating the extent to which anaesthesia affects the outcome of PET neuroimaging in animals. While no final conclusion can be drawn concerning the 'best' general anaesthetic for PET neuroimaging in laboratory animals, such studies provide findings that can enhance an understanding of neurobiological mechanisms in the living brain.

  20. Schizophrenia: do men and women suffer from the same disease?

    Directory of Open Access Journals (Sweden)

    Heinz Häfner

    2002-01-01

    Full Text Available This article reviews the literature on normal brain development and behavioural development in men and women as well as on aetiological risk factors for schizophrenia, such as pre-, peri- and postnatal complications. The male-female comparisons of age and type of onset, symptomatology, course and outcome were based on a population-based sample of 232 first illness episodes - the ABC Schizophrenia Study sample. The probands were assessed using the IRAOS interview and other instruments retrospectively at first admission and prospectively at six cross sections over five years after first contact. A representative subsample of 130 first admissions or 115 first illness episodes were compared with 130 controls, matched by age, sex and area of residence. Women, 3 to 4 years older than men at illness onset, showed a second peak of onsets in age group 45 to 50 years. After animal experiments and a controlled clinical study this finding was explained by a protective effect of oestrogen persisting until menopause. The underlying neurobiological mechanism consisted in a sensitivity reducing effect of oestrogen on D2 receptors in the brain. The effect of oestrogen, meanwhile confirmed in randomised control trials, also includes genomic effects as well as interactions with free-radical detoxifying systems, thus demonstrating the neuroprotective capabilities of oestrogen. Postmenopausal schizophrenia was more frequent and more severe in women. Men fell ill more frequently and more severely at young age and less frequently and more mildly later in life. Illness course, too, was more unfavourable in postmenopausal women than in their male peers. The protective effect of oestrogen in women depended on the degree of their predisposition to the illness: the higher the familial load for schizophrenia, the weaker the protection by oestrogen. The more favourable illness course in premenopausal women resulted from their higher level of social development at illness

    Purpose This mixed-methods exploratory study identified and then developed and validated a quantitative measure of a new construct of mental suffering in the occupied Palestinian territory: feeling broken or destroyed. Methods Group interviews were conducted in 2011 with 68 Palestinians, most aged 30–40, in the West Bank, East Jerusalem, and the Gaza Strip to discern local definitions of functioning. Interview participants articulated of a type of suffering not captured in existing mental health instruments used in regions of political conflict. In contrast to the specific difficulties measured by depression and PTSD (sleep, appetite, energy, flashbacks, avoidance, etc.), participants elaborated a more existential form of mental suffering: feeling that one’s spirit, morale and/or future was broken or destroyed, and emotional and psychological exhaustion. Participants articulated these feelings when describing the rigors of the political and economic contexts in which they live. We wrote survey items to capture these sentiments and administered these items—along with standard survey measures of mental health—to a representative sample of 1,778 32–43 year olds in the occupied Palestinian territory. The same survey questions also were administered to a representative subsample (n = 508) six months earlier, providing repeated measures of the construct. Results Across samples and time, the feeling broken or destroyed scale: 1) comprised a separate factor in exploratory factor analyses, 2) had high inter-item consistency, 3) was reported by both genders and in all regions, 4) showed discriminate validity via moderate correlations with measures of feelings of depression and trauma-related stress, and 5) was more commonly experienced than either feelings of depression or trauma-related stress. Conclusions Feeling broken or destroyed can be reliably measured and distinguished from conventional measures of mental health. Such locally grounded and contextualized

    International Nuclear Information System (INIS)

    To determine the frequency of anxiety and depression in patients with chronic low backache and to document other co-morbidities among these patients presenting at rheumatology clinic of a tertiary care hospital in Islamabad. Study Design: Cross sectional study. Place and Duration of Study: Study was conducted at Pakistan Institute of Medical Sciences from July 2012 to April 2013. Methodology: A total of 170 chronic low backache patients were administered urdu translated Zung Self-Rating Depression Scale and Zung Self-Rating Anxiety Scales. Scoring was done on Likert-type scale of 1-4 (based on these replies: a little of the time, some of the time, good part of the time, most of the time) with overall assessment by cumulative score ranging from 20 to 80, where 20-44 was normal range, 45-59 mildly depressed/anxious, 60-69 moderately depressed / anxious and 70 and above severely depressed / anxious. Results: Out of 170 patients, 157 patients above 18 years of age with male to female ratio 2:3 completed the study. Among study sample 72.2% had mild depression, 21.6% had mild anxiety, 32% had mixed mild anxiety and depression, 0.8% had severe depression, 1.6% had severe anxiety while 2.4% suffered from severe mixed symptoms. Overall, 125 (79.6%) patients were suffering from mild to severe form of depression and anxiety both alone or mixed. Obesity was present in 34 (21.66%) of patients with chronic backache and out of these 29 (85.3%) had psychological co-morbidity. Conclusion: Two thirds of the chronic backache patients reporting at rheumatology clinic of a tertiary care hospital were suffering from mild to severe degree of depression and anxiety. This worrying situation calls for thorough systematic evaluation of all chronic backache patient arriving at rheumatology clinic for mood disorders and psychological ailment. (author)

    Experiencing past adversity traditionally has been linked to negative life outcomes. However, emerging evidence suggests that heterogeneity exists with respect to links between adversity and resilience, with adversity often enhancing cooperation in the face of joint suffering. Here, the authors present 2 studies designed to examine if the severity of past adversity is associated with an enduring propensity for empathy-mediated compassion, and, if so, whether the resulting compassion directly is, in turn, linked to behavior meant to relieve the suffering of others. Using both MTurk and laboratory-based paradigms, the authors find that increasing severity of past adversity predicts increased empathy, which in turn, is linked to a stable tendency to feel compassion for others in need. In addition, they demonstrate that the resulting individual differences in compassion appear to engender behavioral responses meant to assist others (i.e., charitable giving, helping a stranger).

    Full Text Available In China, brucellosis is an endemic disease and the main sources of brucellosis in animals and humans are infected sheep, cattle and swine. Brucella melitensis (biovars 1 and 3 is the predominant species, associated with sporadic cases and outbreak in humans. Isolates of B. abortus, primarily biovars 1 and 3, and B. suis biovars 1 and 3 are also associated with sporadic human brucellosis. In this study, the genetic profiles of B. melitensis and B. abortus isolates from humans and animals were analyzed and compared by multi-locus variable-number tandem-repeat analysis (MLVA. Among the B. melitensis isolates, the majority (74/82 belonged to MLVA8 genotype 42, clustering in the 'East Mediterranean' group. Two B. melitensis biovar 1 genotype 47 isolates, belonging to the 'Americas' group, were recovered; both were from the Himalayan blue sheep (Pseudois nayaur, a wild animal. The majority of B. abortus isolates (51/70 were biovar 3, genotype 36. Ten B. suis biovar 1 field isolates, including seven outbreak isolates recovered from a cattle farm in Inner Mongolia, were genetically indistinguishable from the vaccine strain S2, based on MLVA cluster analysis. MLVA analysis provided important information for epidemiological trace-back. To the best of our knowledge, this is the first report to associate Brucella cross-infection with the vaccine strain S2 based on molecular comparison of recovered isolates to the vaccine strain. MLVA typing could be an essential assay to improve brucellosis surveillance and control programs.

    Silkworm could be an alternative to provide edible animal protein in Controlled Ecological Life Support System (CELSS) for long-term manned space missions. Silkworms can consume non-edible plant residue and convert plant nutrients to high quality edible animal protein for astronauts. The preliminary investigation of silkworm culture was carried out in earth environment. The silkworms were fed with artificial silkworm diet and the leaves of stem lettuce ( Lactuca sativa L. var. angustana Irish) separately and the nutritional structure of silkworm was investigated and compared, The culture experiments showed that: (1) Stem lettuce leaves could be used as food of silkworm. The protein content of silkworm fed with lettuce leaves can reach 70% of dry mass. (2) The protein content of silkworm powder produced by the fifth instar silkworm larvae was 70%, which was similar to the protein content of silkworm pupae. The powder of the fifth instar silkworm larvae can be utilized by astronaut. (3) The biotransformation rate of silkworm larvae between the third instar and the fifth instar could reach above 70%. The biotransformation cycle of silkworm was determined as 24 days. (4) Using the stem lettuce leaves to raise silkworm, the coarse fiber content of silkworm excrements reached about 33%. The requirements of space silkworm culture equipment, feeding approaches and feeding conditions were also preliminarily designed and calculated. It is estimated that 2.2 m 3 of culture space could satisfy daily animal protein demand for seven astronauts.

    A comparative histomorphometric study was carried out on the extension of lacunocanalicular network in two types of bone tissue (woven and parallel-fibered) in shaft bones of various animals (Frog, Chicken, Rabbit, Bovine, Horse, Dog, Man), with the aim to understand whether the distribution of osteocyte network is related to the organization of the collagen fibers or to the animal species. By means of a light microscope (LM) connected with an image-Analyser the following parameters were measured: 1) the cross-sectional area and the volume of osteocyte lacunae; 2) the osteocyte density; 3) the number of canaliculi departing both from the whole outline of the sectional area of osteocyte lacunae and, in the parallel-fibered osteons only (both with LM and SEM), from their two opposite walls, i.e., from the wall facing the Haversian canal (vascular wall) and from that facing the cement line (peripheral wall). In all the animals studied the size and density of osteocyte lacunae as well as the extension of the canalicular network proved to be markedly higher in woven than in parallel-fibered bone, whereas no relation with the species was found. These findings suggest that the function of osteocyte is mainly involved in the regulation of skeletal homeostasis, as discussed in the present paper. PMID:9882957

    Full Text Available This project was aimed to evaluate immunostimulatory effects of three therapeutic substances in broilers suffering from infectious bursal disease (IBD. For this purpose, 150 chicks were divided into five equal groups i.e. A, B, C, D and E having 30 birds each. Group A, B, C and D were challenged with infectious bursal disease virus. There were three immunostimulatory treatments i.e. levamisole (group A, vitamin E (group B, and bursinex (group C. Groups D and E were untreated control. Bursa body weight index, histopathology of bursa of Fabricius, plasma cell counting in Harderian gland and estimation of antibody response against infectious bursal disease virus was recorded. Vitamin E played a major role in improving the condition of birds suffering from infectious bursal disease, as it showed increased bursa body weight index (BBIx, less histopathological lesions in bursa of Fabricius, increased number of plasma cells in Harderian gland and high antibody response in infectious bursal disease infected broilers as compared to levamisole and bursinex. Levamisole played a minor role in improving condition of birds, while bursinex did not seem to be much effective against infectious bursal disease virus in this study.

    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

    Compassion is an affective response to another's suffering and a catalyst of prosocial behavior. In the present studies, we explore the peripheral physiological changes associated with the experience of compassion. Guided by long-standing theoretical claims, we propose that compassion is associated with activation in the parasympathetic autonomic nervous system through the vagus nerve. Across 4 studies, participants witnessed others suffer while we recorded physiological measures, including heart rate, respiration, skin conductance, and a measure of vagal activity called respiratory sinus arrhythmia (RSA). Participants exhibited greater RSA during the compassion induction compared with a neutral control (Study 1), another positive emotion (Study 2), and a prosocial emotion lacking appraisals of another person's suffering (Study 3). Greater RSA during the experience of compassion compared with the neutral or control emotion was often accompanied by lower heart rate and respiration but no difference in skin conductance. In Study 4, increases in RSA during compassion positively predicted an established composite of compassion-related words, continuous self-reports of compassion, and nonverbal displays of compassion. Compassion, a core affective component of empathy and prosociality, is associated with heightened parasympathetic activity. PMID:25621856

    Full Text Available There is paucity of reports in the demographic knowledge, belief and socio-psychological impact of acne vulgaris sufferers towards the disorder in a black population. This is the first study from Nigeria designed to address this issue. A total of 174 facial acne sufferers completed a self-administered questionnaire, which contained several items mentioning different areas in their belief, knowledge, perception, severity, socio-psychological impact and medication attention. The findings were discussed and compared to those of the Caucasians. The occurrence of the disorder was higher in females (65.0% compared to the males (35.0%. About 54.0% of the female subjects indicated increase in severity of the disorder during their pre-menstrual period. Also 64.9% of acne sufferers indicated increase in severity during the rainy season, while 93.1% of the population implicated stress to perpetuate the severity of the disorder. Most (75.7% of the acne sufferers believed that it is caused by oily diet, 40.8% thought that it is hereditary, while barely 5.2% had at sometime sought doctor's attention. Non- prescription products used by acne sufferers were cleansers and cream/lotions. Psychological abnormalities experienced by the sufferers included social inhibition, depression and anxiety. Pain and discomfort are the psychosomatic symptoms. No major differences were found in the beliefs, misconception and socio-psychological impact of acne sufferers in a black population (Nigeria compared to the Caucasians. There is need to improve the understanding of the disorder in Nigeria through health education programmes

    Sex differences in longevity can provide insights into novel mechanisms of aging, yet they have been little studied. Surprisingly, sex-specific longevity patterns are best known in wild animals. Evolutionary hypotheses accounting for longevity patterns in natural populations include differential vulnerability to environmental hazards, differential intensity of sexual selection, and distinct patterns of parental care. Mechanistic hypotheses focus on hormones, asymmetric inheritance of sex chromosomes and mitochondria. Virtually all intensively studied species show conditional sex differences in longevity. Humans are the only species in which one sex is known to have a ubiquitous survival advantage. Paradoxically, although women live longer, they suffer greater morbidity particularly late in life. This mortality-morbidity paradox may be a consequence of greater connective tissue responsiveness to sex hormones in women. Human females' longevity advantage may result from hormonal influences on inflammatory and immunological responses, or greater resistance to oxidative damage; current support for these mechanisms is weak.

    Mental health problems at work constitute a challenge in the clinical feld, as well in the professional, the economic and the public health perspective. The total costs they generate in Switzerland are equivalent to 3.2% of the Swiss gross domestic product and they very often lead to dismissal. The vast majority of people are treated by their primary care physician. The Institute for Work and Health features a specialized consultation on the topic of suffering at work, offering the primary care physicians a pluridisciplinary advice or support, in a collaborative care prospect. Its action, adapted to each situation's needs, goes from an advice to a referral to specialists that can strengthen the network on a long-term basis (mental health follow-up, supported employment program, legal or social advice).

    Full Text Available Nowadays, ectopic pregnancy is a pathological entity of great incidence, which is increased, among other things, by each time earlier sexual relations. Cornual pregnancy is as a result of the implantation of the blastocyte within the segment of the fallopian tube that goes into the uterus wall or between the tubal ostium and the proximal portion of the isthmus. This is a case of a cornual pregnancy in which the use of ultrasonography played an essential role for its diagnosis, since it is about a patient suffering from sickle cell anemia, where it was not possible to clinically eliminate the possibility of an occlusive vessel crisis as the cause of abdominal pain. Subtotal hysterectomy of the right tube was performed. The patient’s evolution is satisfactory.

    2016-01-01

    Ugo Foscolo, was an Italian poet whose works rank among the masterpieces of Italian literature. Talented and well educated in philosophy, classics, and Italian literature, Foscolo gave literary expression to his ideological aspirations and to the numerous amorous experiences in odes, sonnets, plays, poems and an epistolary novel. Concurrent with his rich literary output, Foscolo's correspondence represents a unique perspective from which to monitor his literary and political views and investigate aspects of his everyday life. Among other interesting information, one can find elements of Foscolo's medical history which is generally unknown. Based on his testimonies we suggest that he suffered of longstanding bladder outlet obstruction presumably due to urethral stricture. In the present article we investigate the possibility that chronic bladder outlet obstruction and the consequent renal insufficiency was attributed to the death of Ugo Foscolo. PMID:26885466

    Vegetative diatonic syndrome was diagnosed in 28,3% of children, arrived to sanatorium from the regions, suffered from Chernobyl catastrophe. In order to make correction of this kind of pathology 62 children had undergone the treatment on the base of specially developed programs: 1-st - complex of spirulina reception, infrared radiation treatment, collar-neck zone massage, 2-nd - glycine reception and collar-neck zone massage, 3-d - short wave frequency therapy on active points (control group - 37 children). As the result, in children of the main group in comparison with control, for certain decreased somatic complains quantity (p=0,008), neurological state (p=0,0009) and autonomic system state (p=0,05) improved. Thus the suggested complexes exert gentle influence upon mane autonomic system characteristics and promote subsidence of clinical manifestation of the vegetative diatonic syndrome. (Authors)

    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

    Since emotions give contradictory signals about animal experimentation in medical science, man's relationship to animals must be based upon reason. Thomas Aquinas argues that man is essentially different from animals because man's intellectual processes show evidence of an abstract mechanism not possessed by animals. Man's rights arise in association with this essential difference. The consequence is that only man possesses true rights by Aquinas's definition; animals have them only by analog...

    The scaling behavior of randomly branched polymers in a good solvent is studied in two to nine dimensions, modeled by lattice animals on simple hypercubic lattices. For the simulations, we use a biased sequential sampling algorithm with re-sampling, similar to the pruned-enriched Rosenbluth method (PERM) used extensively for linear polymers. We obtain high statistics of animals with up to several thousand sites in all dimension 2⩽d⩽9. The partition sum (number of different animals) and gyration radii are estimated. In all dimensions we verify the Parisi-Sourlas prediction, and we verify all exactly known critical exponents in dimensions 2, 3, 4, and ⩾8. In addition, we present the hitherto most precise estimates for growth constants in d⩾3. For clusters with one site attached to an attractive surface, we verify the superuniversality of the cross-over exponent at the adsorption transition predicted by Janssen and Lyssy.

  11. Nutritional variations during chemotherapy for patients suffering from a locally advanced oesophagus cancer

    International Nuclear Information System (INIS)

    As de-nutrition is frequently noticed for patients suffering from a locally advanced oesophagus cancer, the authors report a study of the variations of nutritional parameters during chemotherapy and of their impacts of the treatment process and efficiency. Thus, different parameters have been studied at the beginning, during and at the end of the treatment: weight, albumin range, body weight index, calorie survey, and the nutritional support type. The authors observe very important variations with a significant impact on treatment tolerance and efficiency. Short communication

  12. Chernobyl sufferers in Ukraine and their social problems: short outline

    International Nuclear Information System (INIS)

    This paper describes the historical review on the Chernobyl catastrophe. The state was badly prepared to a disaster of such a scale as Chernobyl and most of necessary decisions were drafted and taken immediately when they were needed. Fortunately in the initial period there were material and resources available and a mechanism of direction was in place. The mechanism was not perfect, and its quality was quickly deteriorating. The executive power of the USSR -Council of Ministers and numerous ministries- behaved practically independently from the Supreme Soviet Parliament until 1989. The first period was marked by attempts to hide and to diminish the consequences. The Law had been passed by the Parliament of Ukrainian SSR on 28 february, 1991. Later the Law underwent some serious amendments in 1992, 1993, 1996, mainly because an application of the Law revealed some economic miscounts. Some controversial provisions of the law, like the tax exempt status of the organizations working in the contaminated area, and the import laws for the Chernobyl organizations have been already revoked. In this paper we will pay special attention to informal non-governmental help from international community. Few projects of international organizations, very often quite negatively perceived by Ukrainian people, require separate analysis.The goal of these projects was to offer research assistance to respective Ukrainian institutions and thus these projects were to some extent not directly aimed at suffers, but at some medical problems. Intergovernmental assistance to suffers was quite limited. Ukrainian writers were the the first who begun campaign to disclose the truth of Chernobyl in Ukraine. In 1998 the first green' NGO was created in Ukraine. These NGOs played an important role of pressure groups. Often local politician were using supports from these groups in their election campaigns and legislative works. Separate investigation is needed to asses the role and results of activities

  14. 3Rs-respecting animal models in radiopharmaceutical research with a special emphasis to monoclonal antibodies

    International Nuclear Information System (INIS)

    In better developed human medical centres hybrid (or fusion) diagnostic imaging (PET/CT, SPECT/CT, PET/MRI …) is available for clinicians to detect, localize, stage and follow-up theire patients suffering a wide variety (oncological, cardiovascular, neurological, orthopaedic …) of diseases. Easy to understand that not only human and veterinary clinical but numerous research applications could be implemented using these novel digital imaging methods. The use of hybrid equipments is not simply an expensive toy in researcher’s hands but and effective tool that serves 2 out of the 3 Rs (Refinement and Reduction) requirements as well. Hybrid (fusion) imaging method allows high-resolution pictures including correct anatomical structures and quantized functional data as altogether after radiolabelled ligand applications. Serial images could be taken using only one single anesthetized animal that must not be exterminated at the end of process. The re-use of laboratory animals allowing us to compare the characteristics of different labelled molecules in the very same biological model. Spontaneously diseased canine, feline and exotic animals is a constant source of animal models for the biomedical research and represents a great choice to replace laboratory animals. Osteosarcoma, mammary gland carcinoma, thyroid carcinoma, brain tumours and a few others in dogs or cats might be the best known animal models of the appropriate human diseases. Diagnosing and then treating them with the most promising human methods (including cold MoAbs, immunotherapy, radiolabelled ligands ...) is a chance for the suffering animals, a new hope for owners and referral vets - and parallel applicable data for human oncologists and translational researchers. Authors wish to share with audience their 20 years expert in the field and hope to find friends and co-operators among them. (author)

  15. Animal models of ADHD.

    Bari, A; Robbins, T W

    2011-01-01

    Studies employing animal models of attention-deficit/hyperactivity disorder (ADHD) present clear inherent advantages over human studies. Animal models are invaluable tools for the study of underlying neurochemical, neuropathological and genetic alterations that cause ADHD, because they allow relatively fast, rigorous hypothesis testing and invasive manipulations as well as selective breeding. Moreover, especially for ADHD, animal models with good predictive validity would allow the assessment of potential new therapeutics. In this chapter, we describe and comment on the most frequently used animal models of ADHD that have been created by genetic, neurochemical and physical alterations in rodents. We then discuss that an emerging and promising direction of the field is the analysis of individual behavioural differences among a normal population of animals. Subjects presenting extreme characteristics related to ADHD can be studied, thereby avoiding some of the problems that are found in other models, such as functional recovery and unnecessary assumptions about aetiology. This approach is justified by the theoretical need to consider human ADHD as the extreme part of a spectrum of characteristics that are distributed normally in the general population, as opposed to the predominant view of ADHD as a separate pathological category.

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

  17. Positron emission tomography in patients suffering from HIV-1 infection

    International Nuclear Information System (INIS)

    This paper reviews currently available PET studies performed either to improve our understanding of the pathogenesis of HIV-1 infection or to assess the value of PET imaging in the clinical decision making of patients infected with HIV-1 presenting with AIDS-related opportunistic infections and malignancies. FDG PET has shown that HIV-1 infection progresses by distinct anatomical steps, with involvement of the upper torso preceding involvement of the lower part of the torso, and that the degree of FDG uptake relates to viral load. The former finding suggests that lymphoid tissues are engaged in a predictable sequence and that diffusible mediators of activation might be important targets for vaccine or therapeutic intervention strategies. In lipodystrophic HIV-infected patients, limited available data support the hypothesis that stavudine-related lipodystrophy is associated with increased glucose uptake by adipose tissue as a result of the metabolic stress of adipose tissue in response to highly active antiretroviral treatment (HAART). Finally, in early AIDS-related dementia complex (ADC), striatal hypermetabolism is observed, whereas progressive ADC is characterized by a decrease in subcortical and cortical metabolism. In the clinical setting, PET has been shown to allow the differentiation of AIDS-related opportunistic infections and malignancies, and to allow monitoring of side effects of HAART. However, in patients suffering from HIV infection and presenting with extracerebral lymphoma or other human malignancies, knowledge of viraemia is essential when interpreting FDG PET imaging.

    Compassion is one of the essential components which enable individuals to enter into and maintain relationships of caring. Compassion tends to motivate us to help people who are emotionally suffering. It is also known that a feeling of intrinsic reward may occur as a result of experiencing compassion for others. We conducted this study to understand the neural nature of compassion for other people's emotional state. Twenty-one healthy normal volunteers participated in this study. We used a 2 x 2 factorial design in which each subject was asked to assume a compassionate attitude or passive attitude while viewing the sad or neutral facial affective pictures during functional magnetic imaging. The main effect of a compassionate attitude was observed in the medial frontal cortex, the subgenual frontal cortex, the inferior frontal cortex and the midbrain regions. A test of the interaction between a compassionate attitude and sad facial affect revealed significant activations in the midbrain-ventral striatum/septal network region. The results of this study suggest that taking a compassionate attitude towards other people's sad expressions modulate the activities of the midbrain-ventral striatum/septal region network, which is known to play a role in the prosocial/social approach motivation and its accompanied rewarding feeling.

  19. Cranial MRI of neurologically impaired children suffering from neonatal hypoglycaemia

    International Nuclear Information System (INIS)

    Background. Metabolic disturbances such as anoxia and hypoglycaemia are important in causing maldevelopment of the neonatal brain. While there have been some pathology studies of the effects of neonatal hypoglycaemia on brain development, reports of MRI findings in such infants have been rare. Objectives. To describe the MRI findings in neurologically handicapped children who had suffered from neonatal hypoglycaemia and to evaluate the relationship between the neurological impairment and neonatal hypoglycaemia. Materials and methods. We retrospectively evaluated the MRI findings in eight full-term infants with neonatal symptomatic hypoglycaemia who later exhibited neurological handicap. The age at which the MRI scans were obtained ranged from 9 months to 8 years 10 months (mean 4 years 1 month, median 4 years). Results. The most striking findings were prolonged T1 weighting and T2 weighting in the parieto-occipital periventricular deep white matter in six patients, suggesting abnormal or delayed myelination. Dilatation of the lateral ventricles, especially of the trigones, was observed in five patients in whom the distance between the posterior horns of the lateral ventricles and the adjacent sulci was reduced. The volume of white matter relative to grey matter was reduced in two patients. In addition, four patients exhibited cerebral cortical atrophy, mainly in the occipital lobe. Conclusions. These findings suggest that neonatal hypoglycaemia may cause delayed or abnormal myelination, especially in the parieto-occipital, periventricular, deep white matter, and may cause cerebral cortical atrophy, especially in the occipital lobe.

    Full Text Available Background: Role of personality and some components of behaviors, traits and emotions as effective factors on coronary heart diseases (CHD were presented nearly 50 years ago with the concept of “type A” behavior, a compound of hostility, impatience, competitiveness and dominance. Later studies showed crucial role of other traits and behaviors like anger, introversion, depression and forgiveness. Objective: The aim of this study was to compare personality type and forgiveness in the patients suffering from cardiovascular diseases based on gender. Materials and method: The cross sectional study was designed and sample was collected from men and women referred to cardiologists (within the age range of 23-75 years old from the patients of Shahid Rajaee Heart Hospital of Tehran, Iran from December 2010 to March 2011. Total 87 subjects were selected using random method. The study subjects were given two questionnaires: personality type A (with two factors: TA1, pathologic behaviors of type A personality and TA2, non pathologic behaviors of type A personality and Interpersonal Forgiveness Inventory (IFI, with three subscales namely reestablishment of relationship, control of revenge and realistic perception. Data were analyzed using SPSS software. Results: Mean(±SD age of men was 50.5±11.6 years (n=33 and 55.7±14.4 years in women (n=54. Mean duration of suffering from cardiovascular diseases in men was 7.8 years and in women was 9.10 years. The study found high mean scores of type A pathologic but not non pathologic type A among women compared to men (p<0.038 and no statistically significant differences in forgiveness subscales. Conclusion: The study revealed significant difference between women and men suffering from cardiovascular disease in pathologic type A (TA1 and negative relationship between pathologic type A and forgiveness.

    2011-01-01

    A large literature shows that caregivers of chronically ill older adults have a higher risk for impaired health and decreased longevity. In this paper we review research that addresses pathways through which family members experience negative health consequences from exposure to a partner's suffering. We first provide a conceptualization of suffering and describe how it can be measured, then review empirical evidence that exposure to suffering uniquely influences caregivers' health, and discuss individual differences in caregivers' emotional reactions to partners' suffering using three emotion theories (Gross' process model of emotion regulation, attachment theory, and a functionalist perspective on emotion). Finally, we discuss implications of the effects of suffering for the health and well-being of family caregivers. PMID:21731560

  9. Alternatives to animal experimentation in basic research.

    Gruber, Franz P; Hartung, Thomas

    2004-01-01

    In contrast to animal testing required by law to guarantee minimum safety standards for the licensing of drugs and chemicals, there are no regulations in basic research forcing scientists to perform animal tests. By (usually) free choice, questions are posed and hypotheses are examined which, in many cases, can only be answered by means of animal tests. Just as easily, different questions could be asked or different hypotheses could be examined which do not require animal tests. The only criterion for the choice of a topic is its relevance which cannot necessarily be judged in the short-term. Thus, it is up to the individual scientist to judge what is worth studying and therefore worth animal consumption. The educated mind will consider ethical aspects of this choice. However, on the other hand, this decision is largely influenced by questions of efficacy or (in a negative sense) by the obstacles posed to an animal consuming approach. Here, peer review and general attitude will strongly influence the methodology chosen. Availability and awareness of adequate in vitro techniques represent the prerequisites for the use of alternative methods. The least one can do in basic research is to avoid tests which cause severe suffering to animals, as is required in Switzerland and other European countries by binding ethical principles and guidelines. The increasing standard of approval and control procedures has improved the situation over the years. There are many examples of successful alternative methods in basic research. But, the application of such methods is in most cases limited to the laboratories in which they were developed, calling for technology transfer. Exceptions are procedures that are used worldwide, like the production of monoclonal antibodies, which instead of using the ascites mouse can also be performed in vitro with some good will. In these cases, commercialisation of the techniques has aided their spread within the scientific community. Sadly, many

    Mata, Luis; Sanz, David; Razquin, Pedro

    2014-01-01

    The Explorer(®) 2.0 tube test is a microbial inhibition test for the screening of antimicrobial residues in food samples. The new e-Reader(®) device coupled to Explorer(®) 2.0 operates by incubation at a selected temperature, determination of the endpoint of the assay and interpretation to generate results. This system was validated for muscle samples according to the European Commission Decision 2002/657/EC. Sensitivity towards 25 substances from several groups of antimicrobials was investigated in a first step. Detection capabilities for six substances representing the six major antimicrobial groups were also determined in bovine muscle. The detection capabilities for amoxicillin (10 µg l(-1)), cefalexin (200 µg l(-1)), doxycyclin (100 µg l(-1)), sulfamethazine (100 µg l(-1)), tylosin (100 µg l(-1)) and neomycin (200 µg l(-1)) were in all cases at or below the maximum residue limit (MRL). Specificity and applicability of the test were demonstrated with muscle samples from four animal species (bovine, porcine, ovine and poultry) and results were found to be satisfactory. Ruggedness was evaluated on negative and spiked samples with sulfamethazine as a representative antimicrobial. Neither false-positives nor false-negatives were detected when varying the sample volume, the time of pre-incubation, the temperature of incubation and the batch of the test. These results prove that Explorer(®) 2.0 coupled to e-Reader(®) is a valuable tool for the screening of a broad range of antimicrobials in muscle. This new methodology simplifies the analysis and increases the accuracy of interpretation of the test results since the endpoint of the assay is automatically determined and results are interpreted objectively.

    Neidhart, Laura; Boyd, Renee

    2002-01-01

    To better understand the outcomes of companion animal adoptions, Bardsley & Neidhart Inc. conducted a series of 3 surveys over a 1-year period with dog and cat owners who had adopted their pet through either a (a) Luv-A-Pet location, (b) Adopt-a-thon, or (c) traditional shelter. This article suggests opportunities to improve owners' perceptions of their pets and the adoption process through (a) providing more information before adoption about pet health and behaviors, (b) providing counseling to potential adopters to place pets appropriately, and (c) educating adopters to promote companion animal health and retention. Results demonstrate that the pet's relationship to the family unit, such as where the pet sleeps and how much time is spent with the pet, is related to the amount of veterinary care the companion animal receives, and to long-term retention. Satisfaction and retention are attributed to the pet's personality, compatibility, and behavior, rather than demographic differences among adopters or between adoption settings. The age of the companion animal at adoption, the intended recipient, and presence of children in the home also play a role. Health problems were an issue initially for half of all adopted pets, but most were resolved within 12 months. Roughly one fourth of adopters who no longer have their companion animal said their pet died. Characteristics of pets that died support the contention that spaying and neutering profoundly affects a companion animal's life span. Although retention is similar for dogs and cats, mortality is higher among cats in the first year after adoption. PMID:12578739

  13. Basic principles of experimental animals welfare protection

    Directory of Open Access Journals (Sweden)

    Vučinić Marijana

    2007-01-01

    Full Text Available Ethical considerations of animal protection and welfare require that the use of experimental animals is limited as much as possible. Animal experiments should only be performed when no alternative is available and when the benefit of the experiment outweighs the suffering of the animal. This review paper describes the basic principles for the ethical use of experimental animals. These are: "Three Rs rule" (replacement, reduction and refinement, "five freedoms" for animals and "Solna principles". "Replacement" means the substitution for conscious living higher animals of insentient material. "Reduction" means reduction in the numbers of animals used to obtain information of a given amount and precision. "Refinement" means any decrease in the incidence or severity of inhumane procedures applied to those animals which still have to be used. The "five freedoms" are: freedom from hunger and thirst, freedom from adverse environmental impacts, freedom from disease and injury, freedom to exhibit normal behavior and freedom from adverse mental states. "Solna principles" state that tests for regulatory purposes need to reflect the following: biological Relevance (meaningfulness and usefulness of a test for a particular purpose, Reliability (reproducibility of results within and between laboratories, and Regulatory acceptability (suitability of a test for risk assessment purposes (human health /environment.

    Full Text Available Background: Asthma is a serious public health problem throughout the world and its prevalence has increased in last 2-3 decades. Allergens are one of the many factors which trigger an attack of asthma. Skin prick test is useful in identifying the offending allergen in bronchial asthma. Aim: To identify the possible offending allergens in patients of bronchial asthma. Materials and Methods: The study was a descriptive study conducted at allergy center, Kempegowda Institute of Medical Sciences Hospital and Research Center, Bangalore from January to December 2011. Skin prick test was done in 139 patients suffering from bronchial asthma using 49 allergens extracts. Statistical Analysis: Frequency, proportions, Chi-square test, odds ratio, and 95% confidence interval was used. Results: Out of 139 patients who underwent the skin prick tests, 40% (56 were males and 60% (83 were females. Majority, that is, 60% were in the age group of 21-40 years. Forty-three percent (60 had family history of asthma/atopy, 80% (111 had allergic rhinitis, 24% (34 had chronic urticaria, and 24% (33 had allergic conjunctivitis. Out of 139 patients, 100 (71.94% were sensitive for one or more allergens. The common offending allergens found in the study were dust mites (Dermatophagoides farinae and D. pteronyssinus (DF and DP - 49.28%, dusts - 7.2%, pollens - 6.77%, insects - 6.62%, fungi - 4.53%, and epithelia - 1.92%. Conclusion: The most common allergens in bronchial asthma were dust mites followed by dusts and pollens. Identifying possible allergens in asthma patients help in allergen avoidance and immunotherapy in these patients.

  15. Positive affects and the transformation of suffering into flourishing.

    Fosha, Diana

    2009-08-01

    Three investigative realms with widely divergent methodologies arrive at uncannily similar conclusions about the vital role of positive affective phenomena in optimal adaptation, resilience, affect regulation, cardiac health, and subjective well-being: research on resilience and human flourishing; Indo-Tibetan practices and the emergent yogic sciences; and the practice of AEDP (Accelerated Experiential Dynamic Psychotherapy), a healing-oriented, transformation-based model of psychotherapy. AEDP has explored the vital role of positive emotions in the process of change in general, and, more specifically, in therapeutic work with painful and overwhelming emotional experience, and has identified and descried a phenomenology of positive affective experiences, including the healing affects, and core state, which signal the operation of healing transformational processes. This chapter focuses on how, in the course of one therapeutic hour--through the moment-to-moment tracking of bodily rooted experience and dyadic affect regulation in the context of a relationship in which the individual feels safe and known--the processing of suffering, i.e., stress-based, traumatizing, painful emotional experiences naturally culminates in flourishing, i.e., deeply positive experiences of aliveness, hope, faith, clarity, agency, simplicity, compassion, joy, and truth. Key to this is the focus on and experiential processing of the experience of healing transformation. Thus, there unfolds a series of cascading transformations, with each transition somatically marked by positive transformational affects, until we arrive at core state, a state characterized by the positive affective phenomena that underlie some of our highest strivings and deepest joys.

    Numerical viscosity has long been a problem in fluid animation. Existing methods suffer from intrinsic artificial dissipation and often apply complicated computational mechanisms to combat such effects. Consequently, dissipative behavior cannot be controlled or modeled explicitly in a manner independent of time step size, complicating the use of coarse previews and adaptive-time stepping methods. This paper proposes simple, unconditionally stable, fully Eulerian integration schemes with no nu...

  18. Relieving suffering at the end of life: practitioners' perspectives on palliative sedation from three European countries.

    Seymour, Jane E; Janssens, Rien; Broeckaert, Bert

    2007-04-01

    This paper reports findings from visits to palliative care settings and research units in the UK, Belgium and the Netherlands. The aim was to learn about clinicians' (both nurses and doctors) and academic researchers' understandings and experiences of palliative sedation for managing suffering at the end of life, and their views regarding its clinical, ethical and social implications. The project was linked to two larger studies of technologies used in palliative care. Eleven doctors, 14 nurses and 10 researchers took part in informal interviews. Relevant reports and papers from the academic, clinical and popular press were also collected from the three countries. The study took place in a context in which attention has been drawn towards palliative sedation by the legalisation of euthanasia in the Netherlands and Belgium, and by the re-examination of the legal position on assisted dying in the UK. In this context, palliative sedation has been posited by some as an alternative path of action. We report respondents' views under four headings: understanding and responding to suffering; the relationship between palliative sedation and euthanasia; palliative sedation and artificial hydration; and risks and uncertainties in the clinician-patient/family relationship. We conclude that the three countries can learn from one another about the difficult issues involved in giving compassionate care to those who are suffering immediately before death. Future research should be directed at enabling dialogue between countries: this has already been shown to open the door to the development of improved palliative care and to enhance respect for the different values and histories in each.

  20. Ethical and Animal Welfare Considerations in Relation to Species Selection for Animal Experimentation.

    Science.gov (United States)

    Webster, John

    2014-01-01

    Ethical principles governing the conduct of experiments with animals are reviewed, especially those relating to the choice of species. Legislation requires that the potential harm to animals arising from any procedure should be assessed in advance and justified in terms of its possible benefit to society. Potential harms may arise both from the procedures and the quality of the animals' lifetime experience. The conventional approach to species selection is to use animals with the "lowest degree of neurophysiological sensitivity". However; this concept should be applied with extreme caution in the light of new knowledge. The capacity to experience pain may be similar in mammals, birds and fish. The capacity to suffer from fear is governed more by sentience than cognitive ability, so it cannot be assumed that rodents or farm animals suffer less than dogs or primates. I suggest that it is unethical to base the choice of species for animal experimentation simply on the basis that it will cause less distress within society. A set of responsibilities is outlined for each category of moral agent. These include regulators, operators directly concerned with the conduct of scientific experiments and toxicology trials, veterinarians and animal care staff; and society at large. PMID:26479009

    Though soft tissue disorders have been recognized and described to some detail in several types of domestic animals and small mammals for some years, not much progress has been made in our understanding of the biochemical basis and pathogenesis of these diseases in animals. Ehlers-Danlos syndrome described in dogs already in 1943 and later in cats affects mainly skin in these animals. The involved skin is thin and hyperextensible with easily inflicted injuries resulting in hemorrhagic wounds and atrophic scars. Joint laxity and dislocation common in people are less frequently found in dogs. No systemic complications, such as organ rupture or cardiovascular problems which have devastating consequences in people have been described in cats and dogs. The diagnosis is based on clinical presentation and on light or electron microscopic features of disorganized and fragmented collagen fibrils. Several cases of bovine and ovine dermatosparaxis analogous to human Ehlers-Danlos syndrome type VIIC were found to be caused by mutations in the procollagen I N-proteinase (pnPI) or ADAMTS2 gene, though mutations in other sites are likely responsible for other types of dermatosparaxis. Cattle suffering from a form of Marfan syndrome were described to have aortic dilatation and aneurysm together with ocular abnormalities and skeletal involvement. As in people mutations at different sites of bovine FBN1 may be responsible for Marfan phenotype. Hereditary equine regional dermal asthenia (HERDA), or hyperelastosis cutis, has been recognized in several horse breeds as affecting primarily skin, and, occasionally, tendons. A mutation in cyclophilin B, a chaperon involved in proper folding of collagens, has been identified in some cases. Degenerative suspensory ligament desmitis (DSLD) affects primarily tendons and ligaments of certain horse breeds. New data from our laboratory showed excessive accumulation of proteoglycans in organs with high content of connective tissues. We have

    Aquatic insects find their habitat from a remote distance by means of horizontal polarization of light reflected from the water surface. This kind of positive polarotaxis is governed by the horizontal direction of polarization (E-vector). Tabanid flies also detect water by this kind of polarotaxis. The host choice of blood-sucking female tabanids is partly governed by the linear polarization of light reflected from the host's coat. Since the coat-reflected light is not always horizontally polarized, host finding by female tabanids may be different from the established horizontal E-vector polarotaxis. To reveal the optical cue of the former polarotaxis, we performed choice experiments in the field with tabanid flies using aerial and ground-based visual targets with different degrees and directions of polarization. We observed a new kind of polarotaxis being governed by the degree of polarization rather than the E-vector direction of reflected light. We show here that female and male tabanids use polarotaxis governed by the horizontal E-vector to find water, while polarotaxis based on the degree of polarization serves host finding by female tabanids. As a practical by-product of our studies, we explain the enigmatic attractiveness of shiny black spheres used in canopy traps to catch tabanids.

  9. Radioimmunological vasopressin determination in the urine of patients suffering from hypertension and lung carcinomas

    International Nuclear Information System (INIS)

    The AVP content of the 24 h urine was investigated in 43 patients suffering from hypertension and 80 patients suffering from bronchial carcinoma. With 103.2 +- 52.4 ng, the AVD content of the 24 h urine of 21 untreated hypertensives was highly significantly (p < 0.005) increased compared to that of healthy persons (67.5 +- 34.3 n = 45). During antihypertensive therapy, an AVP value of 80.4 +- 40.5 different from that of untreated patients (p < 0.05) was measured in 64 24 h urines. High AVD values in hypertensives were attributed to a possible stimulation of AVP secretion by renin-angiotensin. Of 67 patients in whom the diagnosis 'bronchial carcinoma' had been histologically-cytologically confirmed, three with small-cell carcinomas had 203.0, 337.8, and 692.5 ng AVP/24 h urine without exhibiting the clinical symptoms of a Schwartz-Bartter syndrome. The other 64 patients had an AVP value of 53.0 +- 31.9. The fraction of lung carcinomas secreting AVP appears to be relatively high. (orig.)

    This study develops a way of analyzing moisture movement in unsaturated expansive soil slope. The basic equations and the integrated finite difference method for moisture movement in unsaturated soils are briefly described, and the calculation code MFUS2 has been developed. The moisture movements in unsaturated expansive soil slopes suffering precipitation were simulated numerically. The simulation results show that expansion or contraction must be taken into account in an analysis model. A simplified equivalent model for calculating rainwater infiltration into expansive soil slopes has been developed. The simplified equivalent model divides the soil slope into two layers according to the extent of weathering of the soil mass at depth. Layer Ⅰ is intensively weathered and moisture can be fully evaporated or rapidly absorbed. The moisture movement parameters take into account the greater soil permeability caused by fissures. Layer Ⅱ is unweathered and the soil is basically undisturbed. The moisture movement parameters of homogeneous soils are applicable. The moisture movements in unsaturated expansive soil slopes suffering precipitation were simulated numerically using the simplified equivalent model. The simulation results show that the moisture movement in the expansive soil slope under rainfall permeation mainly takes place in the extensively weathered layer Ⅰ, which closely simulates the real situation.

    Full Text Available Abstract Background Previous studies have associated chronic pelvic pain with a stereotyped pattern of movement and posture, lack of normal body sensations, a characteristic pain distribution. We aimed at evaluating if these postural changes are detectable in baropodometry results in patients with chronic pelvic pain. Methods We performed a prospective study in a university hospital. We selected 32 patients suffering from chronic pelvic pain (study group and 30 women without this pathology (regular gynecological work out - control group. Pain scores and baropodometric analysis were performed. Results As expected, study group presented higher pain scores than control group. Study and control groups presented similar averages for the maximum pressures to the left and right soles as well as soles supports in the forefeet and hind feet. Women suffering from chronic pelvic pain did not present differences in baropodometric analysis when compared to healthy controls. Conclusions This data demonstrates that postural abnormalities resulting from CPP could not be demonstrated by baropodometric evaluation. Other postural measures should be addressed to evaluate pelvic pain patients.

    Objective: To determine whether the children suffering from Attention -deficit/hyperactivity disorder (ADHD) had neurochemical abnormalities in basis ganglia and if the state could be affected by methylphenidate. Methods: Proton magnetic resonance spectroscopy scans were performed on bilateral globus pallidum of 12 ADHD body before and after one dose of methylphenidate 10 mg. Spectral peaks of N-acetylaspartate (NAA), choline (Cho), myo-inositol (MI), glutamate plus glutamine (α-Glx) and creatine (Cr) were measured and their ratios were compared with 12 age-, handedness-, and IQ-matched healthy boys. Results: In children having ADHD, NAA/Cr ratio decrease significantly in bilateral globus pallidum (left side t = 7.01, P 0.05; right side t = -1.04, P > 0.05). The post-drug NAA/Cr ratios in ADHD children remained significantly different from those in healthy children (left side t = 3.68, P 0.05). Conclusion: In children suffering from ADHD, neuronal loss-dysfunction exists in bilateral striatum. One does of methylphenidate could not affect the state significantly. Further investigations are needed to confirm whether the cholinergic system is involved in ADHD

    2014-12-01

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

    2015-01-01

    Animal welfare is a state within the animal and a scientific perspective provides methodologies for evidence-based assessment of an animal's welfare. A simplistic definition of animal welfare might be how the animal feels now. Affective experiences including emotions, are subjective states so cannot be measured directly in animals, but there are informative indirect physiological and behavioural indices that can be cautiously used to interpret such experiences. This review enunciates several key science-based frameworks for understanding animal welfare. The biological functioning and affective state frameworks were initially seen as competing, but a recent more unified approach is that biological functioning is taken to include affective experiences and affective experiences are recognised as products of biological functioning, and knowledge of the dynamic interactions between the two is considered to be fundamental to managing and improving animal welfare. The value of these two frameworks in understanding the welfare of group-housed sows is reviewed. The majority of studies of the welfare of group-housed sows have employed the biological functioning framework to infer compromised sow welfare, on the basis that suboptimal biological functioning accompanies negative affective states such as sow hunger, pain, fear, helplessness, frustration and anger. Group housing facilitates social living, but group housing of gestating sows raises different welfare considerations to stall housing, such as high levels of aggression, injuries and stress, at least for several days after mixing, as well as subordinate sows being underfed due to competition at feeding. This paper highlights the challenges and potential opportunities for the continued improvement in sow management through well-focused research and multidisciplinary assessment of animal welfare. In future the management of sentient animals will require the promotion of positive affective experiences in animals and this

    2001-01-01

    The demand for renunciation of killing animals has already been discussed by mankind since ancient times. Many arguments for and against this demand have accumulated in the meantime. The reproaches of the vegetarians repeatedly forced the ones who eat meat to justify their diet. Today most of these historical justifications however have to be rejected because of lacking plausibility. Many of the vegetarian arguments on the other hand must be rejected for similar reasons as well. Remaining as morally convincing is the demand for doing the killing absolutely painless and without frightening the animals, which was already formulated for example by Kant and Schopenhauer. Arguments which consider this way of killing as still immoral belong in a broad sense to the "anthropocentric" animal ethics. They do not belong to what is called in Germany "pathocentric" animal ethics, because an animal that is killed without being frightened or tortured, has not suffered, for it hasn't consciously realized anything like danger or harm. We do even argue that these animals are not harmed at all, because it seems senseless to talk about harm without negative conscious phenomena. To push ahead a ban on animal slaughter for moral reasons could be itself morally wrong because it would disturb indirectly many people's conscious well-being without being justified by protecting an animal's conscious well-being. It is however possible to derive from a general duty not to make animals suffer (pathocentric animal ethics) a duty to boycott food of animal origin if these animals had to suffer during their lives.

    Full Text Available The aim of this paper is to contribute to answering the conceptual question whether there can be weak-willed non-human animals. After some preliminary clarifications concerning the phenomenon of weakness of will three different accounts are examined for the conditions a being has to fulfill in order to be in a position to display weakness of will. It is argued that these conditions are very strong and that there are good reasons to assume that, e.g., only language users can be weak-willed. This is taken as an independent argument for Davidson's thesis that non-human animals which are not language users cannot act intentionally.

    With increasing consumer interest in functional foods, proteins from slaughterhouse side streams can offer interesting application opportunities in this respect. Worldwide, increasing numbers of people are suffering from hypertension and protein deficiency. Hydrolyzed proteins of animal origin may show ACE-inhibitory activity, which is central to the treatment of hypertension. Furthermore, the protein content of, for example, meat products increases markedly through the addition of hydrolyzed proteins, and these protein-rich products are of interest to those suffering from protein deficiency. Through a series of analyses, six selected hydrolysates were analyzed for their application potential in the Danish meat product saveloy. Hydrolyzed pig rectum and bovine diaphragm showed the highest ACE-inhibitory activities, and these activities were maintained in the processed saveloys. The ACE-inhibitory activities could not readily be explained by the amino acid profile. The content of N-compounds in the saveloys increased with increasing addition of hydrolysate, with little difference between the added hydrolysates. A sensory panel assessed the saveloys with added porcine rectum (8%), bovine diaphragm (8%), and bovine heart (4% and 8%) as having the strongest off-flavors (chemical flavor). No increase in salty taste resulting from the addition of hydrolysates was detected in the saveloys. Finally, the consumers found the saveloys too mild in flavor and recommended the addition of more spices. PMID:27004118

    Full Text Available Ethical principles governing the conduct of experiments with animals are reviewed, especially those relating to the choice of species. Legislation requires that the potential harm to animals arising from any procedure should be assessed in advance and justified in terms of its possible benefit to society. Potential harms may arise both from the procedures and the quality of the animals’ lifetime experience. The conventional approach to species selection is to use animals with the “lowest degree of neurophysiological sensitivity”. However; this concept should be applied with extreme caution in the light of new knowledge. The capacity to experience pain may be similar in mammals, birds and fish. The capacity to suffer from fear is governed more by sentience than cognitive ability, so it cannot be assumed that rodents or farm animals suffer less than dogs or primates. I suggest that it is unethical to base the choice of species for animal experimentation simply on the basis that it will cause less distress within society. A set of responsibilities is outlined for each category of moral agent. These include regulators, operators directly concerned with the conduct of scientific experiments and toxicology trials, veterinarians and animal care staff; and society at large.

    From time immemorial, animals have served as models for humans. Like humans, animals too have to undergo several types of elective and emergency surgeries. Several anesthetic techniques and drugs used in humans are also used in animals. However, unlike humans, the animal kingdom includes a wide variety of species, breeds, and sizes. Different species have variable pharmacological responses, anatomy, temperament, behavior, and lifestyles. The anesthetic techniques and drugs have to suit differ...

  13. Rejecting empathy for animal ethics

    all six claims to be problematic, though some are more plausible than others, and argue that empathy is indeed not psychologically central to producing moral concern for animals. I also review evidence indicating that other moral emotions, particularly anger, are more strongly engaged with producing...... moral concern for animals, and are thus more capable of achieving various normative aims in animal ethics. The conclusion of my argument is that empathy should lose its currently privileged place....... evidence that could confirm or disconfirm this thesis comes from research on empathizing with animals. However, this evidence has not been discussed in any of the prominent critiques of empathy. In this paper, I investigate six different empirical claims commonly made about empathy toward animals. I find...

  14. SKIN DETECTION OF ANIMATION CHARACTERS

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

    In the paper, we give a survey of animation content in education. At present, there is an extensive literature addressing the impact of animation in education and psychology fields. However, in animation field, although some software companies have developed their individual production toolboxes or platforms for animation content in education, there is lack of relevant research from the perspective of animation techniques. This paper first gives a survey of current animation content in educat...

  16. Sexual function of women suffering from anorexia nervosa and bulimia nervosa.

    The cross-sectional study aimed at examining the sexual function of young adult women suffering from eating disorders. The authors interviewed 53 women (26 with anorexia nervosa and 27 with bulimia nervosa) and 58 female students. Each participant was administered the Female Sexual Function Index, the Eating Attitudes Test, the Body Shape Questionnaire, and the Beck Depression Inventory. Comparisons among the 3 groups showed that patients with anorexia nervosa scored lower in each Female Sexual Function Index subscale than did healthy controls. There was no significant difference between bulimia nervosa and healthy controls. Sexual functionality of patients with anorexia nervosa was correlated only with body mass index (r = 0.5, p =.01). Sexual functionality of patients with bulimia nervosa was correlated only with the Beck Depression Inventory (r = -0.4, p =.03) Patients with anorexia nervosa had more disturbed sexual function than did controls. Sexual function can be related to the level of starvation and symptoms of depression. PMID:24779385

    This article presents a new avenue for healthcare risk managers to drive improvement for patients and healthcare organizations alike: working to reduce avoidable patient suffering. It briefly describes the problem of patient suffering, differentiates between avoidable and unavoidable suffering, and suggests that common risk management tools can be used to tackle the problem. It also highlights a success story from one large health system. PMID:26789746

    The rapid development of intensive livestock industry has greatly increased the discharge of animal manure. Reasonable utilization of large amounts of phosphorus(P)in animal manure can not only save the fertilizer resource, but also avoid water pollution from manure due to direct discharge or excess application in farmland. In this study, P contents and fractionation in 76 animal manures were analyzed using Hedley P fractionation method based on the survey for 52 livestock farms, and P mobility and environmental risks in different manures were evaluated as the reference for manure P management. The results showed that there were significant differences in total P content of animal manures. The mean P contents were 22.5, 13.7, 12.9, 9.6 g P·kg-1 and 7.5 g P·kg-1, in which the proportion of organic P in total P were 33.1%, 41.5%, 66.4%, 28.1%and 36.8%in pig, chicken, duck, cattle and sheep manures, respectively. The contents of total and organic P in non-ruminant animal manure(pig, chicken and duck manures)were 1.7~3.0 times and 2.1~3.0 times greater than that in ruminant manure (cattle and sheep manures)and the proportion of organic P in total P in poultry manure was higher than that in other manures. P mineraliza-tion was easier in non-ruminant animal manure with lower C/P ratio(19~29), compared with that in ruminant manure with C/P ratio of 38~45. Manure P was sequentially extracted by deionized water(H2O-P), NaHCO3(NaHCO3-P ), NaOH(NaOH-P)and HCl(HCl-P). The pro-portion of H2O-P, NaHCO3-P, NaOH-P, HCl-P and residual-P in total P in ruminant animal manure were 27.8%, 32.8%, 18.1%, 15.2%and 6.1%, respectively, while that were 24.6%, 19.4%, 12.7%, 34.4% and 8.9% in non-ruminant animal manure. The significant differences were in NaHCO3-P and HCl-P between ruminant and non-ruminant animal manures. Ruminant manure had greater proportion of liable P (H2O-P and NaHCO3-P)in total P(>60%), but the characteristics of higher mineralization rate might result in fast release

  19. Transfer to animals

    International Nuclear Information System (INIS)

    Data have been compiled to derive animal product transfer coefficients for radionuclides to update the values given in Technical Reports Series No. 364. Significant new data inputs have been incorporated from an extensive review of Russian language information and inclusion of data published since the early 1990s. The resultant database has been used to provide reference transfer coefficient values for a range of radionuclides to (i) cow, sheep and goat milk, (ii) meat (muscle) of cattle, sheep, goats, pigs and poultry and (iii) eggs. The approaches and procedures used to identify and collate data, and assumptions used are given. For most animal products, transfer coefficient values for elements additional to those in Technical Reports Series No. 364 are provided, although some elements were considered in the earlier evaluation which were not included in this review. Differences between the Technical Reports Series No. 364 'expected' values and the reference values from this document, which will be incorporated into the revised transfer parameter handbook, are discussed. An alternative approach to quantifying transfer by using concentration ratios is evaluated and CR values which could be applied across animal species have been provided for milk and meat. Information on fractional gastrointestinal absorption in adult ruminants has been compiled and reference values presented. Despite these improvements many data gaps remain. (author)
