Abstract

This work describes the isolation and structural determination of pharmacological compounds present in the bark of roots of Tabernaemontana catharinensis (Apocynaceae). Among the 27 substances detected 12 were identified as terpenoid-indole alkaloids, 2 steroids and 13 pentacyclic triterpenes. Structures were outlined based on HMQC, COSY, DEPT, 13C, and ¹H NMR data and MS. Spectral data of indole alkaloids were reviewed. An in vitro screening of the extracts and isolated compounds was carried out. Compounds ibogamine (5), 3-oxo-coronaridine (9) and 12-methoxy-4-methylvoachalotine (MMV) demonstrated effective cytotoxicity towards SKBR-3 breast adenocarcinoma and C-8161 human melanoma tumor cell lines.

Abstract

Cell suspension cultures of Tabernaemontana catharinensis were treated with autoclaved homogenates of Candida albicans, Fusarium oxysporum, Penicillium avelanium and Saccharomyces cerevisiae. The effects caused by the concentration, exposure time and the type of elicitor on the accumulation of pentacyclic triterpenes were monitored. When exposed to biotic elicitors for longer periods, some cell lines redoubled the production of those triterpenes. Saccharomyces cerevisiae homogenate was the best elicitor of triterpenes in all cell lines investigated.

Abstract

Background: Biliary tract cancers, which arise from the intrahepatic or extrahepatic bile ducts and the gallbladder, generally have a poor prognosis and are rising in incidence worldwide. The standard-of-care treatment for advanced biliary tract cancer is chemotherapy with gemcitabine and cisplatin. Because most biliary tract cancers have an immune-suppressed microenvironment, immune checkpoint inhibitor monotherapy is associated with a low objective response rate. We aimed to assess whether adding the immune checkpoint inhibitor pembrolizumab to gemcitabine and cisplatin would improve outcomes compared with gemcitabine and cisplatin alone in patients with advanced biliary tract cancer. Methods: KEYNOTE-966 was a randomised, double-blind, placebo-controlled, phase 3 trial done at 175 medical centres globally. Eligible participants were aged 18 years or older; had previously untreated, unresectable, locally advanced or metastatic biliary tract cancer; had disease measurable per Response Evaluation Criteria in Solid Tumours version 1.1; and had an Eastern Cooperative Oncology Group performance status of 0 or 1. Eligible participants were randomly assigned (1:1) to pembrolizumab 200 mg or placebo, both administered intravenously every 3 weeks (maximum 35 cycles), in combination with gemcitabine (1000 mg/m2 intravenously on days 1 and 8 every 3 weeks; no maximum duration) and cisplatin (25 mg/m2 intravenously on days 1 and 8 every 3 weeks; maximum 8 cycles). Randomisation was done using a central interactive voice-response system and stratified by geographical region, disease stage, and site of origin in block sizes of four. The primary endpoint of overall survival was evaluated in the intention-to-treat population. The secondary endpoint of safety was evaluated in the as-treated population. This study is registered at ClinicalTrials.gov, NCT04003636. Findings: Between Oct 4, 2019, and June 8, 2021, 1564 patients were screened for eligibility, 1069 of whom were randomly assigned to pembrolizumab plus gemcitabine and cisplatin (pembrolizumab group; n=533) or placebo plus gemcitabine and cisplatin (placebo group; n=536). Median study follow-up at final analysis was 25·6 months (IQR 21·7–30·4). Median overall survival was 12·7 months (95% CI 11·5–13·6) in the pembrolizumab group versus 10·9 months (9·9–11·6) in the placebo group (hazard ratio 0·83 [95% CI 0·72–0·95]; one-sided p=0·0034 [significance threshold, p=0·0200]). In the as-treated population, the maximum adverse event grade was 3 to 4 in 420 (79%) of 529 participants in the pembrolizumab group and 400 (75%) of 534 in the placebo group; 369 (70%) participants in the pembrolizumab group and 367 (69%) in the placebo group had treatment-related adverse events with a maximum grade of 3 to 4. 31 (6%) participants in the pembrolizumab group and 49 (9%) in the placebo group died due to adverse events, including eight (2%) in the pembrolizumab group and three (1%) in the placebo group who died due to treatment-related adverse events. Interpretation: Based on a statistically significant, clinically meaningful improvement in overall survival compared with gemcitabine and cisplatin without any new safety signals, pembrolizumab plus gemcitabine and cisplatin could be a new treatment option for patients with previously untreated metastatic or unresectable biliary tract cancer. Funding: Merck Sharp & Dohme, a subsidiary of Merck & Co, Rahway, NJ, USA.

Abstract

Introduction: Coronavirus disease 2019 (COVID-19) has become one of the more dramatic health problems in the century. This disease has enormous consequence for the health care worldwide. In addition to high mortality rate, patients recovered from COVID-19 present short and long-term cardiovascular sequelae including chest pain, myocardial dysfunction, arrhythmia, dyspnea, breathlessness, postural tachycardia syndrome, and thrombotic complications. The explanations for these clinical manifestations are still uncertain but can involve a constellation of physiological alterations. Hypothesis: To test if COVID-19 survivors have augmented sympathetic outflow, diminished endothelial function, elevated aortic stiffness, and reduced physical capacity compared to healthy individuals. Methods: Nineteen COVID-19 survivors [age: 47.0±2.3 years, BMI: 30.1±1.2 Kg/m 2 ] and eighteen well-matched healthy controls (age: 44.0±2.0 years, BMI: 28.4 ±1.2 Kg.m 2 ] were included in study. COVID-19 survivors were evaluated within 6 months of original diagnosis by RT-PCR. Muscle sympathetic nerve activity (MSNA) from fibular nerve (Microneurography), brachial artery flow-mediated dilation (BAFMD; Doppler-Ultrasound), carotid-femoral pulse wave velocity (cf-PWV; Complior), beat-to-beat blood pressure (Peripheral BP; Finometer), heart rate (HR; Electrocardiography) and peak oxygen uptake (VO 2peak , Cardiopulmonary exercise testing) were measured in both groups. Results: MSNA was higher in COVID-19 survivors compared to controls (33.0±1.0 vs. 22.0±1.0 bursts/min, p =0.001). Both BAFMD and VO 2peak were lower in COVID-19 survivors compared to controls (4.6±0.7 vs. 8.2 ±0.8%, p =0.005 and 22.2±1.5 vs. 29.7±1.6 mL/Kg/min p =0.001, respectively). Although COVID-19 survivors had greater cf-PWV than controls (8.6±0.5 m/s vs. 7.4±0.4 m/s, p =0.03), BP and HR were not different between groups. Conclusions: Our study revealed that patients recently recovered from COVID-19 have abnormal neurovascular control, vascular alterations and reduced physical capacity. These findings strongly indicate the need of further long-term investigations to uncover cardiovascular sequelae provoked by COVID-19.

Abstract

Incluye contenido parcial de los autores Abstract.Mammalian carnivores are considered a key group in maintaining ecologicalhealth and can indicate potential ecological integrity in landscapes where they occur. Carni-vores also hold high conservation value and their habitat requirements can guide managementand conservation plans. The order Carnivora has 84 species from 8 families in the Neotropicalregion: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; andUrsidae. Herein, we include published and unpublished data on native terrestrial Neotropicalcarnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTRO-PICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data wereobtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organi-zations, and private consultants. Data were collected using several methods including cameratrapping, museum collections, roadkill, line transect, and opportunistic records. Literature(peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated inthis compilation. Most of the data set consists of detection data entries (n=79,343; 79.7%) butalso 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 tomacroecological, ecological, and conservation questions in multiple spatio-temporal perspec-tives. As carnivores play key roles in trophic interactions, a better understanding of their distri-bution and habitat requirements are essential to establish conservation management plans andsafeguard the future ecological health of Neotropical ecosystems. Our data paper, combinedwith other large-scale data sets, has great potential to clarify species distribution and relatedecological processes within the Neotropics. There are no copyright restrictions and no restric-tion for using data from this data paper, as long as the data paper is cited as the source of theinformation used. We also request that users inform us of how they intend to use the data.

Abstract

Dissertação (mestrado)—Universidade de Brasília, Instituto de Ciências Biológicas, Departamento de Ecologia, 2019. O Cerrado é um bioma brasileiro marcado por um mosaico de fitofisionomias. Este, contudo, tem sido ameaçado devido à supressão da vegetação nativa para usos múltiplos. Assim, informações acerca da resposta da fauna silvestre às mudanças na estrutura da vegetação são essenciais, especialmente no Cerrado. O presente estudo avaliou a extensão pela qual a estrutura da vegetação nativa exerce influência sobre a atividade e composição de morcegos insetívoros em uma área de proteção circundada por atividade agrícola. A fim de se estimar a atividade desses morcegos, passes acústicos foram analisados utilizando – se o software Avisoft SASLab Pro. Para identificação das espécies, tais dados foram comparados à literatura. A percentagem de cobertura da vegetação para cada uma das escalas (25m – 300m de raio) foi estimada por imagens de satélite e analisadas no software QGIS 3.6.3. Modelos lineares generalizados foram gerados para analisar a relação entre atividade de morcegos e a porcentagem de cobertura vegetal. Foram contabilizados 4.993 passes de morcegos insetívoros - 15,5% (773) de morcegos de áreas abertas e 70,3% (3,511) de áreas de borda. Os resultados demonstraram que a atividade entre os grupos diferiu (p – value = 0,03423). Os valores de NDVI indicaram presença de vegetação predominantemente caracterizada por formações campestres, com presença de manchas esparsas de formação savânica herbáceo – arbustivas em todos os pontos amostrados. Não houve forte correlação entre atividade de morcegos e porcentagem de cobertura vegetal nas escalas menores que 300m de raio. Tais resultados sugerem que a utilização de escalas espaciais maiores às utilizadas podem ser mais informativas para investigar a resposta de morcegos insetívoros à cobertura vegetal em fitofisionomias savânicas com predominância de formações campestres. Ainda, é possível que a atividade de morcegos insetívoros aéreos seja mais fortemente associada a outras variáveis ambientais não analisadas no presente estudo, como a estrutura da vegetação. Dessa forma, recomenda–se avaliar a resposta de morcegos insetívoros aéreos à vegetação sob múltiplas escalas espaciais Cerrado is a extensive biome in Brazil, characterized by a mosaic of phytophysiognomies. However, it has been severely threatened due to intensive human actions, which promote native vegetation suppression to multiple land uses. Considering those anthropic pressures, information on the wildlife responses to vegetation structure is essential, especially in Cerrado. In this context, the present study aimed to evaluate to what extent vegetation structure strongly influences the activity and species composition of insectivorous bats in a protected area surrounded by agriculture. Insectivorous bat passes were analyzed using the software Avisoft SASLab Pro. After, echolocation passes and feeding buzzes were counted to estimate bat activity and buzz ratio, respectively, in each site. We then identified the passes at species level based on specific literature. To estimate percentage of vegetation cover, we processed satellite images in the QGIS 3.6.3 software to each of the eight circular landscapes scales (25m – 300m in radius). We then modeled the relationship between bat activity and percentage of vegetation cover. Overall, 4.993 insectivorous bat passes were counted, 15.5% (773) IAU and 70.3% (3.511) IAB passes. The results showed bat activity difference between the guilds (p – value = 0.03423). NDVI values revealed low active biomass in all the sites, characterizing grassland areas predominantly, with sparse shrub and herbaceous vegetation in minor percentage. In opposition to the expected, there was no strong correlation between bat activity and percentage of vegetation cover to scales smaller up to 300m in radius. These results suggest that the use of spatial scales relatively larger than those used may be more appropriate and informative to investigate the response of insectivorous bats to vegetation cover in predominant grassland savannah formations. In addition, insectivorous bats may respond stronger to vegetation structure than only percent vegetation cover.

Abstract

Fire is a major disturbance event that affects biomes worldwide, altering vegetation structure and flora and fauna assemblages. Here, we investigated the effects of an extensive wildfire (~ 6240 ha) on small mammal assemblages in savanna woodland (cerradao) at two spatial scales (meso- and macrohabitat) in a neotropical savanna (Brazilian Cerrado). At each spatial scale, we assessed relationships between habitat structure and small mammal species composition and abundance before and after the fire in four natural patches (one burned, three unburned) using partial redundancy analysis. From July 2009 to October 2013, we captured 1319 individuals belonging to 14 species. Our results showed that the fire had consequences for small mammal assemblage at both scales. After the fire, the burned patch differed from the other patches in vegetation attributes and species composition. At a fine scale, fire increased the herbaceous layer and decreased the litter layer and understory obstruction. On a larger scale, the main consequences of fire on vegetation structure were increased variation in litter depth, tree diameter, and distance to the nearest tree. We observed a relationship between mesohabitat structure and the abundance of species with different habitat requirements during the post-fire succession. Fire favored the invasion of generalist species from open Cerrado habitats (rodents Calomys tener, Calomys expulsus, Cerradomys scotti, and Necromys lasiurus) at the expense of more specialized forest species. Our results reinforce the relevance of incorporating multi-scale habitat heterogeneity in future studies assessing the effects of fire on wildlife.

Abstract

Cell suspension cultures of Tabernaemontana catharinensis were treated with autoclaved homogenates of Candida albicans, Fusarium oxysporum, Penicillium avelanium and Saccharomyces cerevisiae. The effects caused by the concentration, exposure time and the type of elicitor on the accumulation of pentacyclic triterpenes were monitored. When exposed to biotic elicitors for longer periods, some cell lines redoubled the production of those triterpenes. Saccharomyces cerevisiae homogenate was the best elicitor of triterpenes in all cell lines investigated.
