ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Resumo A produção agrícola está diretamente relacionada às condições ambientais. Condições favoráveis podem levar a maior produtividade e qualidade do produto. No entanto, as alterações climáticas podem representar uma ameaça para a produção agrícola em todo o mundo, uma vez que um aumento da temperatura pode causar uma diminuição na extensão de áreas adequadas para o cultivo de certas culturas. Utilizando análises espaciais e dados de cenários futuros de mudanças climáticas desenvolvidos pelo Painel Intergovernamental sobre Mudanças Climáticas, este estudo teve como objetivo avaliar o impacto das mudanças climáticas nas plantações de cana-de-açúcar e citros no estado de São Paulo por meio do mapeamento do zoneamento agroclimático. Os resultados deste estudo demonstram que ambas as culturas podem sofrer grandes reduções nas áreas aptas ao cultivo caso haja mudanças severas no regime climático. Essas descobertas podem auxiliar gestores e pesquisadores a mitigar esses potenciais impactos e esclarecer como as mudanças climáticas afetam a vida no planeta, com potencial redução na produção de alimentos e bioenergia. ambientais produto entanto mundo Climáticas canadeaçúcar cana açúcar agroclimático climático planeta bioenergia
Abstract Agricultural production is directly related to environmental conditions. Favorable conditions can lead to higher productivity and product quality. However, climate change may pose a threat to agricultural production worldwide, as an increase in temperature may cause a decrease in the extent of suitable areas for growing certain crops. Using spatial analysis and data from future climate change scenarios developed by the Intergovernmental Panel on Climate Change, this study aimed to evaluate the impact of climate change on sugarcane and citrus plantations in the state of São Paulo using agroclimatic zoning mapping. The results of this study demonstrate that both crops can suffer major reductions in areas suitable for cultivation if there are severe changes in the climate regime. These findings can assist managers and researchers to mitigate these potential impacts and clarify how climate change affects life on the planet, with a potential reduction in food and bioenergy production. quality However worldwide Change mapping regime planet

Abstract Fruits agro-industrial by-products may have a great variety of bioactive compounds that promote health. Thus, the effects of supplementation with acerola, cashew and guava processing by-products for 28 days on retinol level, lipid profile and on some aspects related to intestinal function in rats were investigated. The animals supplemented with different fruit by-products presented similar weight gain, faecal pH values and intestinal epithelial structures; however, they showed higher moisture and Lactobacillus spp. and Bifidobacterium spp. counts in faeces compared to the control group. Supplementation with the cashew by-product decreased the blood glucose, acerola and guava by-products reduced serum lipid levels and all fruit by-products tested increased serum and hepatic retinol. The results indicated that acerola and guava by-products possess a potential hypolipidemic effect. The three fruit by-products increase the hepatic retinol deposition and the faecal populations of beneficial bacterial groups and modulated aspects of intestinal function. The findings of this study can contribute to sustainable fruticulture and support future clinical studies with the supplementation of by-products. agroindustrial agro industrial byproducts by products health Thus 2 level investigated gain structures however spp group byproduct product glucose effect byproducts. products.

Abstract In Compost-Bedded Pack Barn (CBP) systems, air velocity is linked with the thermal comfort of housed dairy cattle and bedding quality and, therefore, assessing ventilation efficiency is essential. In this context, the objective of this study was to evaluate and characterize dependence and spatial distribution of air velocity at the 1.5 m height (vair,M) and at bedding level (vair,B) in an open CBP system with positive pressure ventilation. The study was conducted in 2021, in a facility located in the Zona da Mata region, Minas Gerais, Brazil. The facility area was divided into a mesh composed of 55 equidistant points, where vair,M and vair,B data were collected in the morning (09:00 a.m.) and afternoon (03:00 p.m.) periods, during three weeks in Brazilian winter. Geostatistics techniques were used to assess dependence and spatial distribution. In both periods evaluated, there were a strong occurrence of spatial dependence and non-uniform vair,M and vair,B distributions. The vair,M and vair,B values were lower than recommended (1.8 m∙s–1) in more than 65.0% of the area. Adequate ventilation levels were observed only in the first 20.0 m of the facility, from Southeast to Northwest, because of the fan lines present.

Glioblastoma is the most prevalent and malignant brain tumor identified in adults. Surgical resection followed by radiotherapy and chemotherapy, mainly with temozolomide (TMZ), is the chosen treatment for this type of tumor. However, the average survival of patients is around 15 months. Novel approaches to glioblastoma treatment are greatly needed. Here, we aimed to investigate the anti-glioblastoma effect of the combination of matteucinol (Mat) (dihydroxyflavanone derived from Miconia chamissois Naudin) with the chemotherapeutic TMZ in vitro using tumor (U-251MG) and normal astrocyte (NHA) cell lines and in vivo using the chick embryo chorioallantoic membrane (CAM) assay. The combination was cytotoxic and selective for tumor cells (28 μg/mL Mat and 9.71 μg/mL TMZ). Additionally, the combination did not alter cell adhesion but caused morphological changes characteristic of apoptosis in vitro. Notably, the combination was also able to reduce tumor growth in the chick embryo model (CAM assay). The docking results showed that Mat was the best ligand to the cell death membrane receptor TNFR1 and to TNFR1/TMZ complex, suggesting that these two molecules may be working together increasing their potential. In conclusion, Mat-TMZ can be a good candidate for pharmacokinetic studies in view of clinical use for the treatment of glioblastoma.

Objective: The incidence rate of major depression in adolescents reaches approximately 14%. This disorder is usually recurrent, without remission of symptoms even after pharmacological treatment, and persists throughout adult life. Since the effects of antidepressants take approximately 2 weeks to begin, new pharmacological therapies are under continuous exploration. Recent evidence suggests that psychedelics could produce rapid antidepressant effects. In this study, we evaluated the potential antidepressant effects of ayahuasca in a juvenile non-human primate model of depression. Methods: While living with their families, juvenile marmosets (8 males; 7 females) were observed on alternate days for four weeks during a baseline phase. This was followed by 8 weeks of an induced depressive state protocol, the social isolated context (IC), in which the animals were monitored in the first and last weeks. Subsequently, five males and four females were randomly selected for treatment, first with a single administration of saline vehicle (1.67 mL/300 g of body weight, via gavage), followed by a single dose of ayahuasca (1.67 mL/300 g of body weight, via gavage). Both phases lasted 1 week and the animals were monitored daily. A third week of sampling was called the tardive-pharmacological effects phase. In all phases the marmosets were assessed for behavior, fecal cortisol levels, and body weight. Results: After IC, the animals presented typical hypocortisolemia, but cortisol recovered to baseline levels 24 h after an acute dose of ayahuasca; this recovery was not observed in vehicle-treated animals. Additionally, in males, ayahuasca, but not the vehicle, reduced scratching, a stereotypic behavior, and increased feeding. Ayahuasca treatment also improved body weight to baseline levels in both sexes. The ayahuasca-induced behavioral response had long-term effects (14 days). Thus, in this translational juvenile animal model of depression, ayahuasca presented beneficial effects. Conclusions: These results can contribute to the validation of ayahuasca as an antidepressant drug and encourage new studies on psychedelic drugs as a tool for treating mood disorders, including for adolescents with early-onset depression.

RESUMO Avaliou-se a influência da somatotropina recombinante bovina (rbST) sobre os metabolismos energético e mineral de búfalas entre 63e 154 dias em lactação. Foram utilizadas 22 búfalas, distribuídas em dois grupos experimentais: grupo rbST - aplicação de 500mg de rbST a cada 14 dias; grupo Controle - sem aplicação de rbST. A cada sete dias, foram coletadas amostras de sangue para a determinação do perfil bioquímico e mensuraram-se a produção de leite e o escore de condição corporal dos animais. As médias dos parâmetros estudados para os grupos rbST e Controle foram, respectivamente: produção de leite (PL): 6,44kg vs. 6,68kg; escore de condição corporal-ECC (1-5): 3,51 vs. 3,57; glicose: 70,58 vs. 64,81mg/dL (P = 0,0003); colesterol: 132,38 vs. 133,40mg/dL; triglicérides: 29,18 vs. 28,32mg/dL; proteína total: 8,57 vs. 8,75g/dL; albumina: 3,47 vs. 3,60g/dL; ureia: 32,46 vs. 33,86mg/dL; creatinina: 1,27 vs. 1,39mg/dL; cálcio:10,25 vs. 10,73mg/dL; fósforo:5,76 vs. 5,62mg/dL; e magnésio:3,70 vs. 3,70mg/dL. O uso de 500mg de rbSTinfluenciou o metabolismo da glicose, porém não modificou a PL, o ECC e os níveis dos demais parâmetros metabólicos estudados.
ABSTRACT The aim was to evaluate the influence of recombinant bovine somatotropin (rbST) on the energy and mineral metabolism of buffaloes between 63 - 154 days in milk. Twenty-two buffaloes distributed in two experimental groups were used: Group rbST (n= 11) - application of 500mg of rbST every 14 days; Control Group (n= 11) - no rbST. Every seven days, blood samples were taken to determine the biochemical profile, and milk production and body condition score were measured. The averages of the variables for rbST and Control groups were, respectively: milk yield (MY) - 6.44kg vs. 6.68kg; body condition score (BCS) - 3.51 vs 3.57 (1-5); glucose - 70.58 vs. 64.81mg/dL (P = 0.0003); cholesterol - 132.38 vs. 133.40mg/dL; triglycerides -29.18 vs. 28.32mg/dL; total protein - 8.57 vs. 8.75g/dL; albumin - 3.47 vs 3.60g/dL; urea - 32.46 vs 33.86mg/dL; creatinine - 1.27 vs 1.39mg/dL; calcium - 10.25 vs. 10.73mg/dL; phosphorus - 5.76 vs 5.62mg/dL; and magnesium - 3.70 vs 3.70mg/dL. Use of 500mg rbST influenced glucose metabolism, but did not modify the MY, BCS and the levels of the other metabolic parameters studied.

ABSTRACT Leishmania infantum is an etiologic agent of visceral leishmaniasis. This disease is a neglected disease that can be fatal if not treated and additionally, the few therapeutic option present several drawbacks, including difficult route of administration and toxicity, which turn the search for new therapeutic alternatives necessary. Herein, we evaluated the leishmanicidal in vitro activity of the solanum extract from Solanum lycocarpum A. St.-Hil., Solanaceae, and the isolated alkaloids solasodine, solamargine and solasonine against promastigotes and intracellular amastigotes of L. infantum. Solasodine (IC50-pro = 4.7 µg/ml; IC50-ama = 10.8 µg/ml) and solamargine (IC50-pro = 8.1 µg/ml; IC50-ama = 3.0 µg/ml) exhibited interesting leishmanicidal ativity. Solasonine was approximately four-times (Selective Index 3.7) more selective to the parasite than to the host cells. This data suggest that solasonine might be considered as a potential drug candidate for leishmaniasis treatment.

RESUMO: A Zona da Mata de Minas Gerais possui uma cadeia especializada de produção de leite de cabra. O leite de cabra é superior em qualidade em comparação com o leite de outras espécies domésticas, e a demanda por leite e produtos lácteos do público tem aumentado. Os dados sobre o sistema de criação de cabras leiteiras em Minas Gerais são escassos e relativamente antigos, e essa falta de informação limita a implementação de medidas profiláticas, especialmente para a mastite, que representa o maior problema sanitário nos rebanhos leiteiros. Isso também causa problemas socioeconômicos e problemas de mercado para a criação de cabras leiteiras. O objetivo deste trabalho foi caracterizar a mastite e as bactérias associadas em cabras leiteiras na Zona da Mata de Minas Gerais. Um total de 539 cabras em lactação foi examinado e 268 amostras individuais (uma por teto) foram coletadas de animais positivos no teste da caneca de fundo escuro e/ou Califórnia Mastitis test (CMT). As culturas microbiológicas foram realizadas em meio Agar sangue e as bactérias foram submetidas a testes fenotípicos, genotípicos e testes de susceptibilidade antimicrobiana. A prevalência de mastite subclínica foi de 28,0% e a prevalência clínica foi de 2,8%. A multiplicação bacteriana foi obtida em 62,0% das amostras. Cento e oitenta e sete bactérias foram identificadas. As espécies mais identificadas foram: Staphylococcus aureus (60,4%), seguida de Staphylococcus epidermidis (9.1%,), Escherichia coli (6.9%), Staphylococcus saprophyticus (5.9%) e Staphylococcus caprae (4,3%) em ordem decrescente. As bactérias do gênero Staphylococcus apresentaram um perfil de resistência aos antimicrobianos pertencentes à classe de beta-lactâmicos - penicilina, ampicilina e oxacilina - além da tetraciclina, em contraste com os outros antimicrobianos testados. Doze por cento dos isolados apresentaram resistência múltipla a antibióticos (MDR) e foram encontrados em cinco microrregiões. Entre as bactérias com maior prevalência de MDR, 38,5% foram E. coli e 10,6% S. aureus. Os produtores da Zona da Mata de Minas Gerais são tecnificados, trabalham com raças leiteiras especializadas praticam e possuem bom manejo. No entanto, algumas medidas relacionadas à profilaxia e ao controle das doenças, como a vacinação, têm baixa adesão ou não são realizadas por falta de assistência veterinária. Este é o primeiro estudo com foco nesta região, que possui grande relevância na produção de leite de cabra no Brasil, fornecendo informações importantes que podem auxiliar na implementação de medidas de profilaxia e controle das doenças, e na manutenção de um fornecimento constante de produtos em quantidade e qualidade suficientemente adequada para a população consumidora.
ABSTRACT: The Zona da Mata of Minas Gerais has a specialized goat milk production chain. Goat milk is superior in quality compared with milk of other domestic species, and the demand for milk and milk products for the public has increased. Data on dairy goat breeding in Minas Gerais are scarce and relatively old, and this lack of information has limited the implementation of prophylactic measures, especially for mastitis, which represents the biggest sanitary problem for dairy herds. The objective of this work was to characterize mastitis and bacteria associated with it in milking goats in the Zona da Mata of Minas Gerais. It also causes socioeconomic problems and market issues for dairy goat farming. A total of 539 lactating goats were examined and 268 individual samples (one for teat) were collected from animals positive for strip cup test and/or the California Mastitis Test (CMT). Microbiological cultures were carried out on blood agar medium and the bacteria were subjected to phenotypic, genotypic and antimicrobial susceptibility tests. The prevalence of subclinical mastitis was 28.0% and the clinical prevalence was 2.8%. Bacterial multiplication was obtained in 62% of samples. One hundred eighty seven total bacteria were identified. The most common species identified was Staphylococcus aureus (60%), followed Staphylococcus epidermidis (9.1%,), Escherichia coli (6.9%), Staphylococcus saprophyticus (5.9%) e Staphylococcus caprae (4.3%). Bacteria of the genus Staphylococcus presented a profile of resistance to antimicrobials belonging to the beta-lactam class (penicillin, ampicillin and oxacillin) in addition to tetracycline, in contrast to the other antimicrobials tested. Twelve percent of multidrug resistence (MDR) was found in five microregions. Among the bacteria with the highest prevalence of MDR, 38.5% were E. coli and 10.6% were S. aureus. The producers of the Zona da Mata of Minas Gerais are technicians who work with specialized dairy breeds and practise good management. However, some measures related to prophylaxis and control of diseases, such as vaccination, have low adherence or are not performed due to a lack of veterinary assistance. This is the first study focusing on this region, which is highly prominent in goat milk production in Brazil. It provides important information that can help in the implementation of measures for the prophylaxis and control of diseases, and for maintenance of a constant supply of products in sufficient quantities and of a quality suitable for the consumer population.

Foram utilizados 654 animais, sendo 334 animais no período seco, dos quais eram 149 matrizes e 185 crias e 320 animais no período chuvoso, sendo 106 matrizes e 214 crias, independente de padrão racial e sistema de criação. As coletas foram realizadas nos meses de novembro e dezembro de 2012 e maio de 2013 no município de Quixadá-Ceará e encaminhadas ao Laboratório de Parasitologia da Embrapa Caprinos e Ovinos na cidade de Sobral-Ceará. Foram coletadas fezes para contagem do número de ovos por gramas de fezes (OPG), contagem de Oocistos por gramas de fezes (OOPG), coprocultura e identificação das espécies de Eimeria com base na morfometria. As matrizes apresentaram maiores médias de ovos do tipo Strongyloidea (372,03) e Strongyloides (8,45) no período seco e no período chuvoso apresentaram maiores médias apenas para Strongyloidea (502,85). O inverso aconteceu com o OOPG, onde as crias apresentaram maiores médias no período seco (9387,41) e no chuvoso (9630,37). O gênero de nematódeo mais frequente na coprocultura foi o Trichostrongylus sp. (63,67%) no período seco e o Haemonchus sp. no chuvoso (66,67%). Em 100% dos rebanhos, foram encontrados oocistos de Eimeria, com 81% dos animais infectados. A ocorrência da eimeriose nas categorias jovens e adultas foi de 64,3% e 83,2% no período seco e de 87,4% e 92,4% no período chuvoso. As espécies identificadas foram: Eimeria alijevi, E. apsheronica, E. arloingi, E. caprina, E. caprovina, E. christenseni, E. hirci, E. jolchijevi e E. ninakohlyakimovae. Nas crias a E. alijevi foi a mais freqüente no período seco e a E. ninakohlyakimovae no chuvoso. Já nas matrizes a espécie E. alijevi apresentou a maior frequência em ambos os períodos. Nos rebanhos estudados foi evidenciado a presença de ovos de nematódeos gastrointestinais e oocistos de Eimeria spp. independente da categoria animal.
ABSTRACT: The objective of this study was to evaluate the occurrence of main gastrointestinal parasites and to quantify and identify the species of Eimeria present in young goats and adults in the city of Quixadá, Ceará, during the dry and rainy season. Six hundred fifty-four animals were used, with 334 animals during the dry season, which were 149 mothers and 185 offspring and 320 animals during the rainy season, with 106 mothers and 214 offspring, independent of breed standard and creation system. Samples were collected in the months of November and December 2012 and May 2013 in the city of Quixadá, Ceará and sent to the Parasitology Laboratory of Embrapa Goats and Sheep at Sobral, Ceará, feces were collected for counting the number of eggs per gram of feces (EPG), counting oocysts per gram of feces (OOPG), coproculture and identification of Eimeria species based on the morphometry. Matrices showed higher means egg type Strongyloidea (372.03) and Strongyloides (8.45) in the dry season and the rainy season had higher mean only to Strongyloidea (502.85). The inverse happened to OOPG, where the offspring showed higher means in the dry season (9387.41) and rainy (9630.37). The genus most frequent of nematode in coprocultures was Trichostrongylus. (63.67%) in the dry season and Haemonchus sp. the rainy (66.67%). One hundred percent of the herds, oocysts of Eimeria were found, with 81% of infected animals. The occurrence of eimeriosis in young and adult categories was 64.3% and 83.2% in the dry season and 87.4% and 92.4% during the rainy season. The species identified were: Eimeria alijevi, E. apsheronica, E. arloingi, E. caprina, E. caprovina, E. christenseni, E. hirci, E.and E. jolchijevi ninakohlyakimovae. In the offspring E. alijevi was the most frequent in the dry season and the rainy E. ninakohlyakimovae. Already in matrices the species E. Alijevi showed the highest frequency in both periods. In herds studied it evidenced the presence of gastrointestinal nematodes eggs and oocysts of Eimeria spp. independent of animal category.

ABSTRACT This study evaluated the chemical composition and antioxidant activity of fatty acids from the marine red algae Pterocladiella capillacea (S. G. Gmelin) Santelices & Hommersand 1997 and Osmundaria obtusiloba (C. Agardh) R. E. Norris 1991. The gas chromatography mass spectrometry (GC-MS) identified nine fatty acids in the two species. The major fatty acids of P. capillacea and O. obtusiloba were palmitic acid, oleic acid, arachidonic acid and eicosapentaenoic acid. The DPPH radical scavenging capacity of fatty acids was moderate ranging from 25.90% to 29.97%. Fatty acids from P. capillacea (31.18%) had a moderate ferrous ions chelating activity (FIC), while in O. obtusiloba (17.17%), was weak. The ferric reducing antioxidant power (FRAP) of fatty acids from P. capillacea and O. obtusiloba was low. As for β-carotene bleaching (BCB), P. capillacea and O. obtusiloba showed a good activity. This is the first report of the antioxidant activities of fatty acids from the marine red algae P. capillacea and O. obtusiloba.

ABSTRACT Phytochemical investigation of Bauhinia acuruana Moric., Fabaceae, resulted in the isolation of sixteen constituents, including two new compounds 2'-hydroxy-2,3,5-trimethoxybibenzyl (1), (2R,3S)-2-(3,4'-dihydroxyphenyl)-5-methoxy-6-methylchroman-3,7-diol (2), together with fourteen known ones (3–16). The structures of the compounds were established by spectroscopic analysis including HR-ESI-MS, 1D and 2D NMR data, followed by comparison with previously reported data from the literature. Compounds 1, 2, 6, 7, 8 and 9 were evaluated for their cytotoxicity, which turned out to be marginal in a panel of six human cancer cell lines.

When aiming to use the strontium isotopic ratio 87Sr/86Sr for the traceability and authentication of wine, it is crucial to understand the impacts of anthropogenic factors and technological processes on this parameter. A study was developed to evaluate the effect of nanofiltration (NF), a membrane process with several applications in oenology, on the isotopic ratio 87Sr/86Sr of wine, testing its robustness as geographical tracer. NF assays, for dealcoholisation, were carried out at laboratory scale with model solutions and white and red wines from Portuguese DO. High rejections to strontium (97%) and tartaric acid (> 70%) and low rejection to ethanol (< 10%) at 15 bar were observed in model solutions. Wines and NF-processed wines (17 bar; 2.1 L/min) were evaluated for physicochemical composition (including phenolic composition, chromatic characteristics and polysaccharides), multi-elemental composition and 87Sr/86Sr ratio by Q-ICP-MS. The preferential membrane permeation of ethanol was associated with a slight increase in the quality parameters of the wine (anthocyanins and polysaccharides). High rejections to mineral elements, including heavy metals, were observed. Rejection to Sr was mostly higher than 95%. No significant differences in the 87Sr/86Sr of wines and corresponding permeate fractions were observed, suggesting that NF does not preclude the use of this parameter for wine traceability purposes.

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.
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.

Com este trabalho objetivou-se avaliar o processo de cicatrização do tendão em coelhos, utilizando-se no grupo tratamento o filme de quitosana, por meio de uma análise clínico-cirúrgica e histológica. Foram utilizados 12 coelhos adultos, separados em grupo controle (GC) e grupo tratamento (GT), nos quais se realizou uma secção parcial do tendão gastrocnêmio de ambos os membros pélvicos. A avaliação clínica baseou-se na presença de reação inflamatória, infecção, dor e deiscência da sutura. Para a avaliação histológica, foi realizado um estudo comparativo do processo cicatricial por meio do tipo de células, da quantidade de tecido conjuntivo e da organização das fibras colágenas entre os grupos e os momentos. Nas feridas cirúrgicas, não foram observadas secreção, dor ou deiscência. Na histologia comparativa entre os grupos, o GC apresentou melhor processo cicatricial em relação ao GT, aos 60 dias. Aos 90 dias, no GT a cicatrização já esboça recuperação do tendão, com reorganização da celularidade e das fibras colágenas no tecido conjuntivo denso modelado. Concluiu-se que a quitosana estimula rápido crescimento celular, mas de forma desorganizada, e que a cicatrização completa só ocorre após 90 dias da sua implantação no tecido.
This work aimed to evaluate the process of tendon healing in rabbits, using the treatment group in chitosan film through a clinical, surgical and histological analysis. In the experiment, 12 adult rabbits were used, divided into control group (CG) and treatment group (TG), which were held in the partial section of the gastrocnemius tendon of both limbs. Clinical assessment was based on the presence of inflammation, infection, pain and suture dehiscence. For histological evaluation a comparative study of the healing process through the cell type, amount of connective tissue and collagen fiber organization was performed between groups and times. In surgical wounds no secretion, pain or dehiscence were observed. In the comparative histology between groups, the CG showed better healing compared to TG, at 60 days. On day 90 the TG already outlines tendon recovery with reorganization of cellularity and collagen fibers in the dense connective tissue modeled. It was concluded that chitosan stimulates faster cell growth, but it is haphazardly, and that complete healing occurs after 90 days of their implantation in tissue.
