Abstract
Reducing one's consumption of foods containing animal products, or avoiding such foods altogether, has become part of everyday life for many people in the Western world. People's motivations for such "animal product limiting" are well-established, but the ways in which individuals enact and experience dietary change in the initial phase are not well understood. Nor is it clear whether, and how, these people present their dietary changes to others. Through the analysis of interviews with 28 people residing in Denmark who had recently (<9 months) embarked on flexitarian, vegetarian or vegan diets, this paper explores how people, in the initial phase of trying to consume fewer, or no, foods with animal products, (i) engage in the practicalities of daily food activities and (ii) communicate their experiences with, and opinions about, the dietary changes they are making in interpersonal interactions. The findings reveal two very different ways of organising the daily food activities: Foodism and Convenience. They also disclose three different ways of communicating in interpersonal interactions: Ethical advocacy, Plant food demonstration and Anonymisation of diet. The paper offers insights into the variation in practices underlying animal product limiting. It suggests that the plant food sector should cater for people relying on convenient food practices as well as those engaged in more advanced ("foodie") practices. Further, in discussing interpersonal communication in the light of community-based social marketing, we argue that the findings highlight how animal product limiters, in everyday social life, may be able to encourage more people to embark on animal product limiting.

Abstract
Assisted reproductive technologies and genetic technologies can accelerate progress in breeding programs in dairy farming, but it is unclear how consumers will react to the use of these technologies. Using representative questionnaire data on Danish citizens (n = 2,036) this cross-sectional study examined consumer attitudes to the application of advanced technologies in dairy cattle breeding. Attitudes were examined in 2 ways. First, we prompted about general attitudes to assisted reproductive technologies and genetic technologies in dairy cow breeding. Here we found that most of the participants were critical of cow impregnation involving hormone therapy and the insertion of cloned fetuses. Second, we used a vignette experiment to study whether acceptance of and willingness to drink milk varies with the type of technique that farmers use for their breeding work, as well as the traits being bred for. We included 5 breeding methods with differing degrees of technological complexity. Participants were randomly assigned to receive tailored information about 1 of the 5 breeding methods. The information specified that dairy farmers' own use of advanced technologies is limited to using semen in artificial insemination on the farm. The potentially concerning technologies are here not applied at farm level but are represented in the semen used in artificial insemination because they were used by breeders on earlier generations of cows and bulls to develop semen with higher genetic merit. There was much less concern about this indirect use of the technologies. Only 1 in 5 participants thought the most advanced method we prompted about (use of semen from breeding methods involving genetic engineering and cloning) was unacceptable. Unwillingness to drink milk from cows produced through such a breeding method was also modest (18%) and not much higher than the unwillingness to drink milk from a cow produced by natural fertilization (10%). A likely reason for the unexpectedly low level of unwillingness to drink milk is that people regard the genetic engineering as distant from the final product. We also found that high-frequency organic milk consumers were more critical of advanced breeding methods. Thus, 28% within this group were unwilling to drink milk from cows impregnated with semen derived from earlier generations of cows and bulls bred using gene editing and cloning. Further, this share rose if the high-frequency organic consumers were very averse to the manipulation of nature. The organic sector may need to cater to this subgroup (e.g., by ensuring the traceability of the semen that organic farmers use to artificially inseminate their cows).

Abstract
A novel technology combining in vitro production and genomic embryo selection is currently under development in dairy cattle breeding. Adoption of this technology will probably accelerate genetic progress toward the main breeding goals of economic interest, as well as allow selection for traits of societal concern such as decreased methane emissions and improved animal welfare. However, dairy farmers, and especially organic farmers, could find the technology morally questionable and reject its use. This cross-sectional study surveyed Danish dairy farmers' general acceptance of the combined technology and their reported likelihood of using semen produced with it. Drawing on diffusion theory, a questionnaire was developed to examine the way farmers discover and communicate about new technological breeding options, and to measure the factors which predict acceptance and likelihood of adopting the technology. The questionnaire was sent to a randomly selected sample of organic and conventional dairy farmers in Denmark, and 85 organic and 71 conventional farmers (41% response rate) completed it. Seventy-six percent of farmers reported that they would be likely to use semen from bulls derived from the technology. A majority (61%) also found the technology acceptable, but many (33%) were unsure or undecided. Most farmers saw the technology as beneficial, but ethical reservations were aired by around a fifth of the farmers. There were no differences between organic and conventional farmers in likelihood of using, perceived utility, and ethical reservations about the technology. Self-reported idealistic organic farmers showed lower acceptance of the technology, but reported similar likelihood of using semen produced by it. Young farmers (20-39 yr) exhibited higher acceptance of the technology. Larger producers (in terms of number of cows) were more likely to report that they will use and accept the technology. We conclude that it is likely that semen from the technology combining in vitro production and genomic selection would be widely used by both organic and conventional farmers provided that costs can be kept low, and that there are advantages in terms of achieving breeding goals. Structural developments, growth in size of dairy farms, acceptance by young farmers, and the fact that economic incentives (and even ethical arguments) seem to favor the technology all point to this conclusion.

Abstract
BACKGROUND The relationship between animal ethics orientations and consumer demand for meat with high standards of animal welfare, and the way this relationship plays out in different countries, is not well understood. Using pork as a case study, this comparative study aims to identify the animal ethics orientations that drive purchases of welfare meat in Denmark, Germany, and Sweden. METHODS Cross-sectional questionnaire data from representative samples of approximately 1600 consumers in each country were collected. A segmentation of pork consumers (using latent profile analysis) was carried out. RESULTS In all three countries, two subgroups were concerned about farm animal welfare: the first subgroup was driven by animal rights values; the second subgroup by animal protection values, where the main principle was that "it is all right to use animals as long as they are treated well". Other consumer groups are less concerned about farm animal welfare and display little or no preference for welfare pork. CONCLUSIONS In all three countries, dual demand for welfare pork exists. The findings of this study can be used, among others, to understand the marketability of enhanced welfare animal products and the potential for market-driven animal welfare improvements.

Abstract
Knowledge of risk factors for canine obesity is an important pre-requisite of effective preventative strategies. This study aimed to investigate risk factors for canine obesity in adult companion dogs across Zealand, Denmark. Client-owned dogs (>2 years of age and without chronic illness) were recruited and examined at eight companion animal veterinary practices in areas with varying socio-economic characteristics. The body condition score (BCS) of the dogs was examined by two investigators based on a 9-point scoring scheme. Dog owners answered a questionnaire that had prompts regarding: 1) dog characteristics, including neuter status, 2) owner characteristics, 3) feeding and exercise practices and 4) the owners' attachment to the dog. The effect of these factors on BCS and the risk of being heavy/obese (BCS scores 7-9) were analysed in two separate analyses. A total of 268 dogs were included in the analysis, of which 20.5% were found to be heavy/obese. The average BCS was 5.46. In terms of dog characteristics, neutering dramatically increased both BCS and the risk of being heavy/obese in male dogs but not in bitches. BCS and the risk of being heavy/obese increased in senior bitches and decreased in senior male dogs. The risk of being heavy/obese was higher in dogs with overweight and obese owners. Regarding feeding and exercise practices, providing only one meal per day increased BCS and risk of being heavy/obese. Treats during relaxation increased the risk of dogs being heavy/obese. It also increased the dogs' BCS, but only if the owners were overweight or obese. An increased duration of daily walking increased the risk of the dog being heavy/obese, but only if the owner was overweight or obese. Allowing the dog to run free in the garden/property decreased the risk of the dog being heavy/obese. The owners' attachment to the dog was not associated with the dogs' BCS or dogs' being heavy/obese. An important and novel finding was that neutering increased the risk of being overweight or obese for male dogs while bitches were at risk irrespective of neuter status. Furthermore, a complex interaction between owners' weight status, feeding practices and the risk of dogs being overweight or obese was found, which stresses the need to consider companion animal obesity from a One Health perspective in future prospective studies. Finally, this study was unable to confirm that canine obesity is a product of owners being too attached to their dogs.

Abstract
Using a survey conducted in four Nordic countries (Denmark, Finland, Norway and Sweden) in 2012, we investigated whether eating out in cafés and restaurants in these countries is best characterized as a workday pattern activity or a leisure activity; and, whether frequent eating at cafés and restaurants is related to socio-demographic factors and factors relevant to the organization of daily life. We found that eating out is not a fundamental part of everyday eating. It is something which takes place occasionally. This may be taken to suggest that eating out in the Nordic countries is primarily a leisure activity. However, while this is an accurate portrayal of Denmark and Norway, eating out in Finland and Sweden is somewhat more common and linked to work-life. This difference probably reflects contrasting historical-institutional paths: in Finland and Sweden a food culture emphasizing cooked lunches and dedicated public policies supporting the provisioning of lunches outside the home may have promoted eating out. Multivariate analysis revealed that eating out declines with age. An urbanization effect exists, as residence in a capital city increases the propensity to eat out. There were socio-economic differences in all countries. We hypothesized that education and status would not significantly explain eating out activity after people's gastronomic interest had been controlled for. However, education was statistically significant in Sweden and Norway, and surprisingly status was negatively associated with eating out in Sweden. As expected, eating out was positively associated with income, and it was more frequent among the higher salariat and the self-employed (although not in Norway).

Abstract
This study examined the extent to which Danish veterinary practices encounter financially limited clients and how different factors relating to the animal, the client and the veterinarian affect decisions to provide treatment for these clients. 300 small animal practices were invited to participate in an online survey. 195 participated, giving a response rate of 65 per cent. The results show that Danish small animal veterinary practices encounter clients with limited finances regularly: 33.8 per cent of them 3-4 times, 24.6 per cent 5-10 times and 19.5 per cent 1-2 times a month. Only around 9 per cent reported having a written practice policy on handling financially limited clients. Factors affecting decisions to treat include the severity and type of the animal's condition, the medical care needed and the client's expressed emotions. The propensity to treat is significantly higher in female veterinarians and in situations involving unborn animals. The overall conclusion is that small animal veterinary practices often provide treatment to clients who are not able to pay-far beyond what is legally required. This can be considered a major economic and psychological challenge for the practising veterinarians.

Abstract
The aim of this study was to investigate the Danish public's support for publicly funded obesity treatment and prevention. It was also examined whether levels of support could be explained by dislike of obese people and/or the belief that those who are obese are personally responsible for their condition. A representative survey of members of the Danish public (N = 1,141) was conducted using a web-based questionnaire. The survey was designed to assess attitudes to public funding for obesity-related health care, and to investigate the impact, on those attitudes, of dislike of obese people, the perceived controllability of obesity, self-reported BMI, and additional attitudinal and socio-demographic characteristics. Public funding of some obesity treatments, such as weight-loss surgery, attracted only limited public support. A majority of the Danish public did support "softer" treatment interventions and preventive initiatives. Attitudes to the treatment of obesity were clearly best predicted by the belief that individuals are personally responsible for their own obesity. Dislike of obese persons had no direct effect on the preference for collective treatment initiatives and only a small effect on support for publicly funded obesity prevention. The high level of disapproval for publicly funded obesity treatment should be cause for concern for decision makers aiming to ensure equal access to health care. Since it is the belief that obese people are personally responsible which explains this disapproval, strategies for challenging public opinion on this issue are discussed.

Abstract
We have analysed the consequences of liposome mediated gene transfer into human primary epidermal keratinocytes and compared non-Epstein-Barr Virus (EBV) and EBV based expression vectors that carry the genes encoding human Growth Hormone (hGH) or Enhanced Green Fluorescent Protein (EGFP). Different kinetics between the non-EBV and EBV based vectors were revealed upon subcultivation of hGH transfected keratinocytes. The keratinocytes transfected with non-EBV based vector showed a rapid reduction in hGH production. Although the EBV based vector resulted in more stable expression, this was also reduced over time. Chromatin inactivation by deacetylation was investigated by treatment with sodium butyrate and found not to be the reason for the decreasing expression. Keratinocytes divided into subpopulations enriched for either stem cells or transit amplifying cells, based on beta1-integrin expression and function, do not differ significantly with respect to susceptibility to productive transfection. However, when the keratinocytes were transfected with the EGFP gene and sorted live by FACS into EGFP negative and positive populations, only the negative cells were capable of forming significant numbers of colonies. This is consistent with the observation that the ability to incorporate BrdU was dramatically reduced in the EGFP expressing population within 24-48 h post transfection indicating an almost complete cell cycle arrest. p53 levels were unaffected by the procedures, and the keratinocyte cell line HaCat, mutated in both p53 alleles, also shows a marked reduction in clonogenic potency upon transfection. There was a slight increase of TUNEL positive apoptotic nuclei in the positive population at early time points. However, the apoptotic index was still very low. When we measured the frequency of involucrin expressing cells, we found an increase in the productively transfected population over time indicating an initiation of terminal differentiation. In contrast to the transfected cultures, keratinocytes that were transduced using a retroviral vector showed no decrease in colony forming efficiency. In conclusion we find that transgene expressing cells from transfected cultures of epidermal keratinocytes undergo cell cycle arrest and initiate terminal differentiation by mechanisms which are independent of p53 levels.

Abstract
A detailed analysis of the subcellular distribution of acyl-CoA esters in rat liver revealed that significant amounts of long-chain acyl-CoA esters are present in highly purified nuclei. No contamination of microsomal or mitochondrial marker enzymes was detectable in the nuclear fraction. C16:1 and C18:3-CoA esters were the most abundant species, and thus, the composition of acyl-CoA esters in the nuclear fraction deviates notably from the overall composition of acyl-CoA esters in the cell. After intravenous administration of the non-beta-oxidizable [(14)C]tetradecylthioacetic acid (TTA), the TTA-CoA ester could be recovered from the nuclear fraction. Acyl-CoA esters bind with high affinity to the ubiquitously expressed acyl-CoA binding protein (ACBP), and several lines of evidence suggest that ACBP functions as a pool former and transporter of acyl-CoA esters in the cytoplasm. By using immunohistochemistry, immunofluorescence microscopy, and immunoelectron microscopy we demonstrate that ACBP localizes to the nucleus as well as the cytoplasm of rat liver cell and rat hepatoma cells, suggesting that ACBP may also be involved in regulation of acyl-CoA-dependent processes in the nucleus.

Abstract
Most disease-causing missense mutations in short-chain acyl-CoA dehydrogenase (SCAD) and medium-chain acyl-CoA dehydrogenase are thought to compromise the mitochondrial folding and/or stability of the mutant proteins. To address this question, we studied the biogenesis of SCAD proteins in COS-7 cells transfected with cDNA corresponding to two SCAD missense mutations, R22W (identified in a patient with SCAD deficiency) or R22C (homologous to a disease-associated R28C mutation in medium-chain acyl-CoA dehydrogenase deficiency). After cultivation at 37 degreesC the steady-state amounts of SCAD antigen and activity in extracts from cells transfected with mutant SCAD cDNAs were negligible compared with those of cells transfected with SCAD wild type cDNA, documenting the deleterious effect of the two mutations. Analysis of metabolically labeled and immunoprecipitated SCAD wild type and mutant proteins showed that the two mutant proteins were synthesized as the 44-kDa precursor form, imported into mitochondria and processed to the mature 41.7-kDa form in a normal fashion. However, the intramitochondrial level of matured mutant SCAD proteins decreased rapidly to very low levels, indicating a rapid degradation of the mutant proteins at 37 degreesC. A rapid initial elimination phase was also observed following cultivation at 26 degreesC; however, significantly higher amounts of metabolically labeled and immunoprecipitated mature mutant SCAD proteins remained detectable. This corresponds well with the appreciable steady-state levels of SCAD mutant enzyme activity observed at 26 degreesC. In addition, confocal laser scanning microscopy of immunostained cells showed that the SCAD mutant proteins were localized intramitochondrially. Together, these results show that newly synthesized SCAD R22W and R22C mutant proteins are imported and processed in the mitochondrial matrix, but that a fraction of the proteins is rapidly eliminated by a temperature-dependent degradation mechanism. Thermal stability profiles of wild type and mutant enzymes revealed no difference between the two mutants and the wild type protein. Furthermore, the turnover of the SCAD mutant enzymes in intact cells was comparable to that of the wild type, indicating that the rapid degradation of the mutant SCAD proteins is not due to lability of the correctly folded tetrameric structure but rather to elimination of partly folded or misfolded proteins along the folding pathway.

Abstract
To characterize disease-causing mutations in the low density lipoprotein receptor (LDL-R) gene, COS cells are transfected with the mutant gene in an EBV-based expression vector and characterized by flow cytometry. Using antibodies against the LDL-receptor the amount of receptor protein on the cell surface is quantitated. The receptor activity is measured by incubating the cells with fluorescence labeled LDL (Dil-labelled LDL) at 37 degrees C and 4 degrees C. The transfected cells stained with anti-LDL-R antibodies can also be analysed by immunofluorescence microscopy allowing the study of the intracellular location of variants of the receptor. To evaluate these methods, we are analyzing four previously well-characterized LDL-R mutations, belonging to each of the classes 2 to 5. Preliminary data show that mutant genes belonging to class 3 and 4A give rise to receptor protein on the cell surface, but impaired LDL uptake, while mutant receptors belonging to class 2A and 5 can only be detected intracellularly. Expression of the class 2A mutation results in an ER staining pattern, whereas the class 5 mutation gives rise to an intracellular staining compatible with localization in the endosomal/lysosomal compartments. We conclude that this system is useful for a rapid functional analysis of newly discovered mutations in the LDL-R gene.

Abstract
Medium-chain acyl-CoA dehydrogenase (MCAD) deficiency is a potentially lethal inherited defect in the beta-oxidation of fatty acids. By comparing the behaviour of five missense MCAD mutant proteins expressed in COS cells and in Escherichia coli, we can define some of these as "pure folding mutants." Upon expression in E. coli, these mutant proteins produce activity levels in the range of the wild-type enzyme only if the chaperonins GroESL are co-overproduced. When overexpressed in COS cells, the pure folding mutants display enzyme activities comparable to the wild-type enzyme. The results suggest that the MCAD mutations can be modulated by chaperones, a phenomenon that may influence the manifestation of the MCAD disease.

Abstract
In situ techniques for the detection of specific chromosomes using centromeric probes and the decoration of entire chromosomes using chromosome painting are well established. However, in the deciphering of complex chromosomal aberrations it is valuable to be able to detect the centromere and the entire DNA of a specific chromosome in different colours simultaneously on the same metaphase. In this report we describe a combination of the primed in situ labelling (PRINS) technique and chromosome painting for simultaneous visualization of centromere-specific oligonucleotides and chromosome painting libraries. A key feature is that the denaturation step in the PRINS reaction is sufficient to keep the chromosomes denatured for chromosome painting. This means that PRINS and consecutive chromosome painting can be performed as a single procedure (PRINS-painting).
