Participants living in Spain were contacted by email and asked to complete an anonymous online questionnaire, in which they answered the Professional Quality of Life scale, the Cognitive and affective empathy test, the Warwick-Edinburgh Mental Well-Being Scale, and their perceived human-animal interaction. Participants were asked whether they were receiving psychological therapy or were taking anxiolytics, hypnotics or antidepressant medication. The study comprised 80 participants. No differences were observed related to personal or professional variables. Participants working with small carnivores reported higher total empathy, and those working with non-human primates reported higher emotional comprehension. Higher human-animal interaction was reported by participants working with small carnivores, farm animals and non-human primates. More than half of the participants reported high levels of mental well-being, positively correlated with emotional comprehension, emphatic joy and compassion satisfaction. Participants working with farm animals reported higher levels of secondary traumatic stress that was positively correlated with human-animal interaction and negatively with mental well-being. Most participants reported low-average levels of burnout, which was negatively correlated with mental well-being. The percentage of animal facility personnel in psychotherapy was higher than in the general population, and the consumption of anxiolytics was a little lower and antidepressants higher. Overall, our results indicate that animal-facility personnel who felt stress or worse mental well-being were in therapy and took medication to improve their condition.</p>","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10187066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonetheless, ethical and regulatory oversight remains limited in many parts of the continent. To strengthen this governance framework, the Pan-African Network for Laboratory Animal Science and Ethics brought together experts from 12 African countries to create an Africa-centric practical guide to facilitate the establishment and appropriate functioning of Institutional Animal Ethics Committees across Africa. The Guidelines are based on universal principles for the care and use of sentient animals for scientific purposes, with consideration of the cultural, religious, political and socio-economic diversity in Africa. They focus on 11 key elements, including responsibilities of institutions and of the Institutional Official; composition of the Committee; its responsibilities, functioning and authority; ethical application and review processes; oversight and monitoring of animal care and use and of training and competence; quality assurance; and the roles of other responsible parties. The intent is for African institutions to adopt and adapt the guidelines, aligning with existing national legislation and standards where relevant, thus ensuring incorporation into practice. More broadly, the Guidelines form an essential component of the growing discourse in Africa regarding moral considerations of, and appropriate standards for, the care and use of animals for scientific purposes. The increased establishment of appropriately functioning animal ethics committees and robust ethical review procedures across Africa will enhance research quality and culture, strengthen societal awareness of animals as sentient beings, improve animal well-being, bolster standards of animal care and use, and contribute to sustainable socio-economic development.</p>","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10919060/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10161732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the time expenditure was compared between both handling techniques. It was possible to use the tunnel in all three mouse strains. However, the impact of the handling techniques on the behavioural parameters investigated in the present study were strain-specific. All behavioural parameters suggested that NZW mice benefited the most from tunnel handling. The results obtained from Hello Kitty and WNK mice were ambiguous, which may suggest that a brief handling session during the cage clean may have not been sufficient to habituate them to the process of handling.

The variety of murine models available, and the ability to create new ones, eclipses all other species, but the size of mice and their organs create challenges for many in vivo studies. For pulmonary research, improved methods to access murine airways and lungs, and track substances administered to them, would be desirable. A nonsurgical endoscopic system with a camera, effectively a bronchoscope, coupled with a cryoimaging fluorescence microscopy technique to view the lungs in 3D, is described here that allows visualization of the procedure, including the anatomical location at which substances are instilled and fluorescence detection of those substances. We have applied it to bacterial infection studies to characterize better and optimize a chronic lung infection murine model in which we instill bacteria-laden agarose beads into the airways and lungs to extend the duration of the infection and inflammation. The use of the endoscope as guidance for placing a catheter into the airways is simple and quick, requiring only momentary sedation, and reduces post-procedural mortality compared with our previous instillation method that includes a trans-tracheal surgery. The endoscopic method improves speed and precision of delivery while reducing the stress on animals and the number of animals generated and used for experiments.</p>","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10693731/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9869318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We recently commenced another study using the same dose and route of delivery of CsA in BALB/cJ mice in order to immune suppress mice to make them susceptible for mouse papillomavirus infection. We highlight in this case report that in contrast to our earlier study, we observed almost immediate unexpected toxicity and had to terminate the recent experiment after only five days of treatment. Seven to eight-week-old female BALB/cJ mice were treated with 75 mg/kg of CsA by oral gavage daily for five days before treatment was stopped due to body weight loss and mice becoming moribund. The probability of survival of the mice following CsA treatment was 80% in this study, compared with 98% in our 2016 study. Mice showed signs of probable acute kidney injury, which was reversible following withdrawal of CsA. Although it is unclear why the clinical response to CsA in BALB/cJ mice differed markedly between the two experiments, this case report highlights the risk of CsA to mouse welfare.

Glucose disappearance rate and areas under the insulin, C-peptide and glucagon curves from the IVGTT were calculated.
