ABSTRACT The Atlantic Forest is made up of different vegetation types over extensive latitude. Most of its remnants are in mountain ranges, which are responsible for the maintenance of most endemic and threatened species in this domain. Here we present the floristic composition of the Área de Proteção Ambiental Mestre Álvaro (APAMA), a coastal massif at Espírito Santo State with expressive altitudinal amplitude (100-800 a.s.l.) containing remnants never floristically studied. Knowing the composition of this protected area is important because it includes an altitudinal range not yet evaluated in floristic comparisons involving highland and lowland forests between the latitudes 18-21° S. We found 493 species (in 292 genera and 91 families): ten are regional endemic species, nine are new records of occurrence for the state, and 52 are under some degree of threat of extinction. Our results indicate the presence of flora elements' typical of both highland and lowland forests, which makes the APAMA essential in a scenario extremely fragmented. Finally, our data provide an unprecedented floristic list for regional forest restoration projects, as well as an invaluable source of data for biogeographic studies that seek to understand the effect caused by neighboring vegetation types on the composition of lowland forests.

Abstract During the last quarter of 2019, the beaches, mangroves, and estuaries of Northeast Brazil received an unprecedented volume of crude oil from the sea, which became the worst environmental disaster ever to reach the Brazilian coast. The oil, having reached the shores completely unnoticed, left both society and government agents completely clueless on (i) where the oil was coming from; (ii) how much oil was still in the ocean to reach the shorelines; and (iii) which beaches were going to be affected next! By exploring remote sensing data and ocean numerical modeling, along with oil dispersion chemistry on sea water, this study investigates the possible origin and path of the spill and whether it could have been detected from space. The oil dispersion modeling simulations performed for this investigation revealed a possible region and timing of the oil spill, also indicating the likelihood of it being advected toward the shoreline under the ocean surface.

Abstract Since the first reported case of COVID-19 in Brazil, the public and private educational system started to close. Up to November 2020, scientific discussions about the return of schooling activities have been rarely performed by the national scientific community and police-makers. The great delay of school returning in Brazil contrasts with successful international strategies of school reopening worldwide and seems counterintuitive with the reopening of non-essential activities. Here, important issues to be considered before and during school reopening are reviewed and discussed. COVID-19 testing is essential to avoid disease spreading, but high cost of individual RT-qPCRs impairs an extensive testing strategy for school returning. To reduce costs and increase the speed of diagnosis, we tested the efficiency of a pooled-sample PCR strategy in a cohort of the educational staff in the city of Macaé/RJ, finding five asymptomatic individuals (0,66%) among the 754 people tested. Thus, a polled-sample PCR testing strategy of the educational staff might prevent infection spreading in schools at a reasonable cost. We discuss how our test strategy could be coupled with internationally recognized safety rules to allow for a safe school return and how countries from different world regions are dealing with educational activities during COVID-19 pandemic.

Abstract Introduction: We investigated the clinical course and outcomes of patients submitted to cardiovascular surgery in Brazil and who had developed symptoms/signs of coronavirus disease 2019 (COVID-19) in the perioperative period. Methods: A retrospective multicenter study including 104 patients who were allocated in three groups according to time of positive real time reverse transcriptase-polymerase chain reaction (RT-PCR) for the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2): group 1, patients who underwent cardiac surgery > 10 days after positive RT-PCR; group 2, patients with a positive RT-PCR within 10 days before or after surgery; group 3, patients who presented positive RT-PCR > 10 days after surgery. The primary outcome was mortality and secondary outcomes were postoperative complications, intensive care unit (ICU) length of stay, and postoperative days of hospitalization. Results: The three groups were similar with respect to age, the European System of Cardiac Operative Risk Evaluation score, and comorbidities, except hypertension. Postoperative complications and death were significantly higher in groups 2 and 3 than in group 1, and no significant difference between groups 2 and 3 was seen. Group 2 showed a high prevalence of surgery performed as an urgent procedure. Although no significant differences were observed in ICU length of stay, total postoperative hospitalization time was significantly higher in group 3 than in groups 1 and 2. Conclusion: COVID-19 affecting the postoperative period of patients who underwent cardiovascular surgery is associated with a higher rate of morbidity and mortality. Delaying procedures in RT-PCR-positive patients may help reduce risks of perioperative complications and death.

ABSTRACT Introduction: Prostate cancer (PC) is the second most commonly diagnosed cancer in males. 68Ga-PSMA PET/CT, a non-invasive diagnostic tool to evaluate PC with prostate-specific membrane antigen (PSMA) expression, has emerged as a more accurate alternative to assess disease staging. We aimed to identify predictors of positive 68Ga-PSMA PET and the accuracy of this technique. Materials and methods: Diagnostic accuracy cross-sectional study with prospective and retrospective approaches. We performed a comprehensive literature search on PubMed, Cochrane Library, and Embase database in search of studies including PC patients submitted to radical prostatectomy or radiotherapy with curative intent and presented biochemical recurrence following ASTRO 1996 criteria. A total of 35 studies involving 3910 patients submitted to 68-Ga-PSMA PET were included and independently assessed by two authors: 8 studies on diagnosis, four on staging, and 23 studies on restaging purposes. The significance level was α=0.05. Results: pooled sensitivity and specificity were 0.90 (0.86-0.93) and 0.90 (0.82-0.96), respectively, for diagnostic purposes; as for staging, pooled sensitivity and specificity were 0.93 (0.86-0.98) and 0.96 (0.92-0.99), respectively. In the restaging scenario, pooled sensitivity and specificity were 0.76 (0.74-0.78) and 0.45 (0.27-0.58), respectively, considering the identification of prostate cancer in each described situation. We also obtained specificity and sensitivity results for PSA subdivisions. Conclusion: 68Ga-PSMA PET provides higher sensitivity and specificity than traditional imaging for prostate cancer.

ABSTRACT Adobe is an efficient construction material for several reasons, such as its thermal comfort, sustainability, and lower energy cost, as well as the simplicity of its production and execution. However, challenges such as water absorption, capillarity, and compressive strength should be investigated to improve its physical and mechanical properties. “Synthetic termite saliva” (STS) is an excellent stabilizer with high cohesive and hydrophobic power. Therefore, the objective of this work was to evaluate the effects of STS incorporation into adobe, analyzing its physical, mechanical and thermal properties. Five treatments were studied: 0 (control); 0.1; 0.2; 0.4 and 0.8% STS by mass. These adobe samples were evaluated according to bulk density, linear shrinkage, capillarity, water absorption, thermal conductivity and compressive strength, according to Norma Técnica de Edificación (NTE) E0.80 testing using a new methodology. Linear shrinkage decreases from 2.7 to 1.91 cm with 0.4% STS. Capillarity decreases with the increasing amounts of STS. Water absorption decreased from 12.03 to 6.31% using 0.4% STS, and its mass was reduced from 779 to 19 grams. The thermal conductivity showed no differences between concentrations. The compressive strength was reduced but was still acceptable based on NTE E.080. The stabilization of the adobe using STS showed an improvement in its physical properties, mainly due to its hydrophobic power.

Abstract Stevia (stevia rebaudiana Bertoni) is a species characterized by producing non-caloric substances with high sweetening potential. Among these substances, rebaudioside A and stevioside are produced in greater quantity. Plant density and harvesting time are factors that affects biomass and sweetening compounds yield in this species. The objective of this research was to evaluate the effect of plant densities and harvesting times on the productive and physiological characteristics of stevia in southern Brazil. The experimental design was in randomized blocks, in a split-plot scheme, with 9 treatments comparing the effect of three planting densities (166 667, 83 333 and 33 333 plants ha-1) in the plots and three harvesting periods (before, in the beginning and in full flowering) in the subplots. Harvesting at the beginning of flowering promoted higher dry leaf biomass yield and, when associated with the lowest planting density, promoted higher levels of rebaudioside A and stevioside. The lowest planting density resulted in greater leaves biomass accumulation, whereas the highest density promoted higher yields per area. Interaction between density of 166 667 plants ha-1 and the harvest at the onset of flowering promoted higher yields of rebaudioside A (43.22 kg ha-1) as well as higher rebaudioside A/stevioside ratio (0.60).

ABSTRACT The elaboration of maps to characterize the spatial variability of soil attributes assists in the strategic planning and decision making of agricultural managers. Precision and accuracy of maps are related to the ideal sampling density to characterize the variability pattern. This study was conducted with the aim of identifying the sampling density to represent the variability of soil physical quality using attributes with different magnitudes of variation in an area cultivated with coffee. Three approaches were used to find the most adequate sampling density (geostatistical analysis, percentage of error associated with the sampling density, and coefficient of variation). A total of 145 soil samples were collected at a depth of 0-0.20 m at the crossing points of a regular grid with a spacing of 50 m. The percentage of clay, silt, and sand, macroporosity, microporosity, total pore volume, and soil density were determined. The data were submitted to descriptive statistical analysis. For elaborating the variability maps with up to 15% error and soil attributes with a coefficient of variation close to 50%, a sampling density of 3 points ha−1 is suggested.

ABSTRACT: Poincianella pyramidalis (catingueira) is a toxic plant associated with abortions, embryonic losses and malformations in goats and laboratory animals. Outbreaks and sporadic cases of spontaneous intoxication in sheep have been reported in the last five years in the agreste of Pernambuco. Due to the occurrence of these spontaneous cases and the lack of researches in sheep, an experimental study was carried out to evaluate the teratogenic effects of P. pyramidalis on sheep. In the experiment, 16 female and three male sheeps, mixed breed, were used. Females were divided in four groups, with four animals per group and maintained in individual stalls, underwent estrus synchronization and mating by natural mating and after 30 days the diagnosis was made to confirm gestation. Groups were named group 1 (G1), group 2 (G2), group 3 (G3), and group 4 (G4). In G1 (control) the ewes were fed with 1% of concentrate supplementation (CS) based on live weight (LW) and 2% of maize silage (MS) with a daily intake of 3% dry matter (DM) based on LW. In G2 feeding was constituted of 1% of CS based on LW and 2% of forage, including 2% of roughage, 50% was hay of P. pyramidalis and the other 50% of DM. In G3 feed was constituted of 1% of CS based on LW and 2% of roughage. Among these 2% of roughage, 80% was hay of P. pyramidalis and the other 20% of DM. In G4 the sheep were fed with 1% CS based on the LW and the roughage consisting of 100% P. pyramidalis hay. All groups received CS with corn meal, cottonseed meal, mineral salt specific for sheep and water ad libitum. Animals were monthly submitted to ultrasonography to detect embryonic or fetal losses. Serological tests were performed for Neospora caninum and Toxoplasma gondii before introduction of the animals in the experiment. Fetuses with malformations were evaluated in the Laboratory of Animal Anatomy and Pathology of the Academic Unit of Garanhuns (UAG), UFRPE, to describe the lesions. In G2, there were five cases of malformations of eight born lambs. In G3, there were four cases of malformation, one due to abortion. In G4, one sheep aborted and the other three gave birth to four malformed fetuses. Main malformations found in the study were arthrogryposis, palatoschisis, chylosquisis, hypoplasia of the mandible, aplasia of the incisive bone, malformations of the eye and tongue, polidactyly and monodactyly. In the groups with higher doses, larger numbers of malformations were observed, and the occurrence of placental retention and the high frequency of perinatal mortality in lambs presenting some type of malformation were noted. It has been demonstrated that P. pyramidalis is an important cause of congenital malformation, abortion and perinatal mortality in sheep, therefore keeping pregnant sheep away from this plant throughout the gestation period is utmost important.
RESUMO: Poincianella pyramidalis (catingueira) é uma planta tóxica associada a abortos, perdas embrionárias e malformações em caprinos e animais de laboratório. Surtos e casos esporádicos de intoxicação espontânea em ovinos vem sendo relatados nos últimos cinco anos no agreste de Pernambuco. Devido à ocorrência destes casos espontâneos e a escassez de pesquisas na espécie ovina, o objetivo desse trabalho foi realizar um estudo experimental para avaliação dos efeitos teratogênicos de P. pyramidalis em ovelhas. No experimento foram utilizadas 16 ovelhas e três carneiros, sem raça definida (SRD). As fêmeas foram divididas em quatro grupos, com quatro animais por grupo e mantidas em baias individuais, foram submetidas a sincronização do estro e acasalamento por monta natural, após 30 dias foi realizado o diagnóstico para confirmação da gestação. Os grupos foram denominados como: grupo 1 (G1), grupo 2 (G2), grupo 3 (G3) e grupo 4 (G4). No G1 (controle) as ovelhas foram alimentadas com 1% de suplementação concentrada (SC) baseado no peso vivo (PV) e 2% de volumoso a base de silagem de milho (SM), com uma ingestão diária de 3% de matéria seca (MS) com base no PV. No G2 a alimentação era constituída de 1% de SC com base no PV e 2% de volumoso. Sendo que destes 2% de volumoso, 50% era feno de P. pyramidalis e os outros 50% de SM. No G3 a alimentação era constituída de 1% de SC com base no PV e 2% de volumoso. Sendo que destes 2% de volumoso, 80% foi de feno de P. pyramidalis e os outros 20% de SM. No G4 as ovelhas foram alimentadas com 1% de SC com base no PV e o volumoso constituído de 100% de feno de P. pyramidalis. Todos os grupos receberam SC à base de farelo de milho, farelo de algodão, sal mineral especifico para ovinos e água ad libitum. Mensalmente os animais foram submetidos à ultrassonografia para detecção de perdas embrionárias ou fetais. Foram realizados exames sorológicos para Neospora caninum e Toxoplasma gondii antes da introdução dos animais no experimento. Os fetos com malformações foram avaliados no setor de Patologia da UFRPE / Unidade Acadêmica de Garanhuns (UAG) para descrição das lesões. No G2, ocorreram cinco casos de malformações de oito cordeiros nascidos. No G3, ocorreram quatro casos de malformação, sendo um decorrente de aborto. No G4, uma ovelha abortou e as outras três pariram quatro fetos malformados. As principais malformações encontradas no trabalho foram artrogripose, palatosquise, queilosquise, hipoplasia da mandíbula, aplasia do osso incisivo, malformações de olho e língua, polidactilia e monodactilia. Nos grupos de maior percentual de ingestão da planta foram observadas maiores quantidades de malformações e chamou a atenção a ocorrência de retenção de placenta e a alta frequência de mortalidade perinatal nos cordeiros que apresentaram algum tipo de malformação. Demonstrou-se com esse trabalho que a P. pyramidalis é uma importante causa de malformação congênita, aborto e mortalidade perinatal em ovinos, sendo de extrema importância que se mantenha as ovelhas prenhes fora do alcance desta planta durante todo o período gestacional.

Perfumes are products mainly consisting of ethyl alcohol, water and fragrance. These fragrances are responsible for characterizing the pleasant and unique odor of each perfume. Among the fragrances, we highlight a group of fragrances which can cause contact allergy, leading to dermatitis. Brazilian and the European law state that when these concentrations of allergenic fragrances exceed the limit of 0.01% for non-rinse products and 0.001% for products with rinsing, the manufacturer is obliged to discriminate on its label their presence. This work aims to quantify allergic fragrances in original and Brazilian perfume using solid-phase microextraction and analyze by gas chromatography-mass detector.

Abstract This study examined the relationship between resting heart rate (RHRr) and anthropometric, metabolic and hemodynamic parameters in subjects aged 80 years and over. One hundred thirteen individuals were divided into two groups (RHR:<66 beats/min and ≥66 beats/min). Anthropometric parameters (weight, height, body mass index and waist circumference (WC) were measured. Hemodynamic parameters (systolic (SBP) and diastolic (DBP) pressure) were measured and pulse pressures (PP) were obtained. Metabolic parameters were fasting blood glucose, triglycerides and total cholesterol. In elderly aged 80 and over, RHR influenced the changes observed in DBP, PP and triglycerides. Additionally, subjects with RHR≥66 beats/min had higher DBP, glucose, total cholesterol and lower PP as compared with elderly with RHR<66 beats/min. Men demonstrated greater weight, height, and WC than women while women had higher percentage of body fat, trunk fat, and higher total cholesterol. Thus, subjects with 80 years old and over who present RHR≥66 have higher DBP and lower PP and heart rate variability compared with the elderly with RHR<66.

Abstract This article proposes a deterministic radio propagation model using dyadic Green's function to predict the value of the electric field. Dyadic is offered as an efficient mathematical tool which has symbolic simplicity and robustness, as well as taking account of the anisotropy of the medium. The proposed model is an important contribution for the UHF band because it considers climatic conditions by changing the constants of the medium. Most models and recommendations that include an approach for climatic conditions, are designed for satellite links, mainly Ku and Ka bands. The results obtained by simulation are compared and validated with data from a Digital Television Station measurement campaigns conducted in the Belém city in Amazon region during two seasons. The proposed model was able to provide satisfactory results by differentiating between the curves for dry and wet soil and these corroborate the measured data, (the RMS errors are between 2-5 dB in the case under study).

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.
Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.

15. Parasitoids of the endangered leafcutter ant Atta robusta Borgmeier in urban and natural areas
Revista Brasileira de Entomologia sep 2013, Volume 57 N. 3 Pages 335 - 339
Parasitoids of the endangered leafcutter ant Atta robusta Borgmeier in urban and natural areas. Hosts of parasitoids in urban areas may suffer from a double threat of habitat destruction by urbanization and parasitism pressure. Moreover, the parasitoids themselves might be at risk if they are specialists. Here, we studied whether Atta robusta (Hymenoptera, Formicidae), which is on the red list of Brazilian threatened species, suffers from higher parasitism pressure in an urban area compared to a natural one. In addition, we determined whether their specialist parasitoids, Eibesfeldtphora breviloba and Myrmosicarius exrobusta (Diptera, Phoridae), are in risk and evaluated whether they are influenced by habitat structure, temperature, humidity, ant traffic, and time of the day. The study was carried out in an urban park and in a natural protected area in the city of Rio de Janeiro. In each site we chose an open area and a closed area (forest) and sampled nine nests in each area. We found that parasitism pressure was similar in urban and natural areas, with the same two parasitoid species present in both areas. The main difference was related to habitat structure, since M. exrobusta was mainly present in open areas while E. breviloba was almost exclusively found in closed areas. Myrmosicarius exrobusta was not present during the hottest midday times, and its abundance was negatively correlated to vapor pressure deficit. These results suggest that green areas can be an important component in efforts to conserve diversity in urban areas. However, the complexity of the habitats in those areas is a fundamental issue in designing urban parks.
