Healing incisional surgical wounds using Rose Hip oil in rats

Purpose: To evaluate incisional surgical wound healing in rats by using Rose Hip (Rosa rubiginosa L.) oil. Methods: Twenty-one days after the oophorectomy procedure, twenty-seven female, adult, Wistar rats were distributed into three groups: Control group (wound treatment with distilled water); Collagenase group (treatment with collagenase ointment); and Rose Hip group (wound treatment with Rose Hip oil). Each group was distributed according to the date of euthanasia: 7, 14 and 21 days. The wound was evaluated considering the macroscopic and microscopic parameters. Results: The results indicated differences in the healing of incisional wounds between treatments when compared to control group. Accelerated wound healing was observed in the group treated with Rose Hip oil in comparison to the control and collagenase, especially after the 14th day. Morphometric data confirmed the structural findings. Conclusion: There was significant effect in topical application of Rose Hip oil on incisional surgical wound healing

Analgesia de animais de laboratório: responsabilidade dos comitês de ética e obrigação dos pesquisadores

Resumo Objetivando avaliar projetos submetidos ao Comitê de Ética no Uso de Animais em relação ao uso de analgesia em cirurgia experimental, este trabalho avaliou 106 projetos, coletando as seguintes informações: metodologia do procedimento cirúrgico, utilização de analgesia, justificativa do não uso de analgésico e aplicação do grau de invasividade. Dos projetos avaliados, 64,2% empregaram técnica cirúrgica. Destes, 65,6% não utilizaram analgesia no pós-operatório, sendo a principal justificativa a de que o analgésico poderia alterar os resultados; em 17%, empregou-se a classificação de grau de invasividade de forma irregular. Assim, o estímulo e a divulgação dos conhecimentos relacionados a analgesia devem partir tanto dos comitês responsáveis quanto do corpo de pesquisadores

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used.
