Determination of Doppler velocimetric measurements of the median artery in horses: Determinação das medidas dopplervelocimétricas da artéria mediana em equinos

Considering the importance of equine culture for the northeast region, the objective was to determine the median artery Doppler velocimetry measurements in horses through Doppler ultrasonography and to correlate changes in these measurements with possible risk factors for laminitis and / or other foot diseases. The project was approved for its execution through protocol N°. 3769100419 granted by the UFPB Ethics Committee. The analyzes were performed at Horse Training Centers and at the Veterinary Hospital - CCA / UFPB, in Areia, Paraíba State. Fourteen animals were used, which were trichotomized at the time of the third metacarpal bone, medial face of both thoracic limbs. The sonoscape S2V ultrasound device with color Doppler coupled to a 7 MHz linear probe was placed at the height of the median artery, in which B was measured. Then, the color Doppler mode was used to determine the doppler velocimeter measurements. Thus, with a 95% confidence interval in mode B 0,509 ± 0,133 of the median artery diameter was determined and in Doppler mode 2,198 ± 1,451 of the pulsatility index and 0,734 ± 0,906 of the resistivity index (non-parametric data). as reference values ​​for normality of median artery vascularization. It is concluded that more studies need to be developed to attest to the reliability of these values. Moreover, they may help in the early diagnosis, improving the prognosis of these animals prone to laminitis and other foot diseases

PARTO CIRÚRGICO: AS MÚLTIPLAS EXPERIÊNCIAS DE MULHERES

Objetivo: conhecer as experiências de mulheres que vivenciaram o parto cirúrgico. Método: estudo qualitativo. Foram realizadas entrevistas com dez mulheres que experienciaram parto cirúrgico em uma maternidade de Salvador, Bahia, Brasil. Posteriormente os dados foram sistematizados mediante a Análise Temática de Bardin. Resultados: as experiências das mulheres sobre o parto cirúrgico são permeadas pelo medo, atrelado principalmente à anestesia raquimedular. Evidenciou também que as condutas adotadas pelos profissionais impactam diretamente sobre essas experiências, visto que podem suprimir a genitora do processo de decisão sobre o tipo de parto, bem como obstaculizar o contato mãe-bebê. Experiências positivas permeadas pelo cuidado também foram apontadas. Conclusão: o estudo sinaliza para a necessidade de mudanças no cenário do parto cirúrgico, o que poderá contribuir para uma prática profissional que prioriza a qualidade da assistência ofertada e favorece o empoderamento das mulheres.Descritores: Cesárea.

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Quercetin Improves Pulmonary Function and Prevents Emphysema Caused by Exposure to Cigarette Smoke in Male Mice

Chronic obstructive pulmonary disease (COPD) is the major cause of morbidity and mortality worldwide, and cigarette smoke is a key factor in the development of COPD. Thus, the development of effective therapies to prevent the advancement of COPD has become increasingly essential. We hypothesized that quercetin protects lungs in mice exposed to long-term cigarette smoke. Thirty-five C57BL/6 mice were exposed to cigarette smoke (12 cigarettes per day) for 60 days and pretreated with 10 mg/kg/day of quercetin via orogastric gavage. After the experimental protocol, the animals were euthanized and samples were collected for histopathological, antioxidant defense, oxidative stress and inflammatory analysis. The animals exposed to cigarette smoke showed an increase in respiratory rate and hematological parameters, cell influx into the airways, oxidative damage and inflammatory mediators, besides presenting with alterations in the pulmonary histoarchitecture. The animals receiving 10 mg/kg/day of quercetin that were exposed to cigarette smoke presented a reduction in cellular influx, less oxidative damage, reduction in cytokine levels, improvement in the histological pattern and improvement in pulmonary emphysema compared to the group that was only exposed to cigarette smoke. These results suggest that quercetin may be an agent in preventing pulmonary emphysema induced by cigarette smoke
