Abstract Cardiovascular diseases are associated with high morbidity and mortality worldwide and have several risk factors, including dyslipidemia, smoking, and hypertension. Studies have evaluated isolated risk factors in experimental models of cardiovascular disease, but few preclinical studies have assessed associations between multiple risk factors. In the present study, hypertensive Wistar rats (Goldblatt 2K1C model) received a 0.5% cholesterol diet and were exposed to tobacco smoke for 8 weeks. During the last 4 weeks, the animals were treated with vehicle, an ethanol-soluble fraction of B. trimera (30, 100, and 300 mg/kg), or simvastatin + enalapril. A group of normotensive, non-dyslipidemic, and non-smoking rats was treated with vehicle. The levels of aspartate aminotransferase, alanine aminotransferase, urea, creatinine, and hepatic and fecal lipids, blood pressure, and mesenteric arterial bed reactivity were evaluated. Cardiac, hepatic, and renal histopathology and tecidual redox state were also investigated. Untreated animals exhibited significant changes in blood pressure, lipid profile, and biomarkers of heart, liver, and kidney damage. Treatment with B. trimera reversed these changes, with effects that were similar to simvastatin + enalapril. These findings suggest that B. trimera may be promising for the treatment of cardiovascular and hepatic disorders, especially disorders that are associated with multiple risk factors.

RESUMO Objetivou-se avaliar a acidez e a disponibilidade de micronutrientes em um Oxisol, de textura média cultivado com soja (verão) e aveia-preta (outono/inverno), após aplicações de lodo de esgoto biodigerido (LB) e de lodo de esgoto centrifugado (LC). O experimento foi conduzido em Botucatu, SP, Brasil, de 2002 a 2014, em delineamento experimental de blocos ao acaso, em esquema fatorial 2 × 4, com quatro repetições. Os tratamentos corresponderam a seis aplicações bienais de LB e LC em quatro doses: 0, 2, 4 e 8 Mg ha-1 (base seca). Após doze anos coletou-se amostras de solo até a profundidade de 0,60 m para avaliação de pH, acidez potencial, acidez trocável e teor de micronutrientes. Aplicações de 4 e 8 Mg ha-1 de LC resultaram, respectivamente, em valores de pH dentro da faixa recomendada até a profundidade de 0,10 e 0,20 m, enquanto aplicações de LB não resultaram em valores de pH adequados para nenhuma camada. O aumento do pH do solo pelas aplicações de LC acarretou diminuição proporcional da acidez potencial do solo, enquanto aplicações de LB resultaram em alto valor de acidez potencial (70 mmolc dm-3) em todas as camadas. Aplicações de LC acarretaram em baixos teores de Al3+ até a profundidade de 0,20 m, enquanto as aplicações de LB acarretaram em altos teores de Al3+ a partir da camada 0,05-0,10 m. Sucessivas aplicações de ambos os lodos resultaram em teores de Cu2+, Fe2+, Mn2+ e Zn2+ que ultrapassaram os valores máximos permitidos em todas as camadas do solo. O boro apresentou baixos teores no solo, e o pH foi o fator determinante para tal.
ABSTRACT The objective of this study was to evaluate the effects of acidity and availability of micronutrients on a sandy clay loam Oxisol grown with soybeans (summer) and black oat (autumn/winter), after long-term applications of biodigested sewage sludge (BS) and centrifuged sewage sludge (CS). The experiment was conducted in Botucatu, SP, Brazil, from 2002 to 2014, using a randomized block design, in 2×4 factorial scheme, with four repetitions. Treatments corresponded to six biennial applications of BS and CS at four doses: 0, 2, 4 and 8 Mg ha-1 (dry basis). Soil samples up to 0.60 m depth were taken after twelve years, and pH, potential acidity, exchangeable acidity and micronutrient contents were evaluated. The CS applications of 4 and 8 Mg ha-1 led to pH values within the recommended range up to depths of 0.10 and 0.20 m, respectively, whereas BS applications did not result in adequate pH values in any layer. The increased soil pH caused by CS applications resulted in a proportional reduction in soil potential acidity, whereas BS applications resulted in high value of potential acidity (70 mmolc dm-3) in all layers. The CS applications resulted in low Al3+ concentrations up to 0.20 m depth, whereas BS applications led to high Al3+ concentrations from the 0.05-0.10 m layer. The successive applications of both sludges resulted in Cu2+, Fe2+, Mn2+ and Zn2+ concentrations that exceeded the maximum values allowed in all soil layers. Low boron concentrations were found in the soil, and pH was the determinant factor for it.

Aedes aegypti is the main vector of three neglected tropical diseases: dengue, zika and chikungunya. Dengue is under surveillance by health organizations worldwide due to the risk of epidemics. Since there is no specific treatment for dengue, most studies have focused on preventing the reproduction and/or development of the mosquitoes. We studied the larvicidal activity of five phosphates and phosphorothioates derived from cardol, one of the four main components of cashew nut shell liquid (Anacardium occidentale L.), at different concentrations. The organophosphorothioate derivatives were tested for their in vitro inhibitory potential against acetylcholinesterase (AChE). One compound, Cdl.i-dPS (median lethal concentration (LC50) = 0.8 ppm), was four times more efficient compared to an important commercial larvicide, Temephos (LC50 = 3.2 ppm), and showed greater AChE inhibition than its monosubstituted analogue and Temephos.

Resumo Nós investigamos os parasitas de cinco espécies de lagartos pertencentes às famílias Phyllodactylidae (Phyllopezus pollicaris e Gymnodactylus geckoides) e Gekkonidae (Hemidactylus agrius, Lygodactylus klugei e Hemidactylus brasilianus) em região semiárida do Brasil. Seis espécies de nematoides foram encontrados: Parapharyngodon alvarengai e Spauligodon oxkutzcabiensis (Pharyngodonidae), Physaloptera lutzi (Physalopteridae), Skrjabinelazia intermedia (Seuratidae), Trichospirura sp. (Rhabdochonidae), Piratuba sp. (Onchocercidae) e uma espécie de cestódeo, Oochoristica sp. (Linstowiidae). As espécies de maiores prevalências foram S. oxkutzcabiensis, a qual infectou P. pollicaris (75%) e P. alvarengai a qual infectou G. geckoides (29.%). Nós documentamos novo registro de hospedeiro para lagartos na América do Sul pertencente ao gênero Trichospirura, o qual é comum em mamíferos, e 16 novas ocorrências de espécies parasitas nas cinco espécies de lagartos aqui estudadas.
Abstract We investigated the parasites of five lizard species belonging to Phyllodactylidae (Phyllopezus pollicaris and Gymnodactylus geckoides) and Gekkonidae (Hemidactylus agrius, Lygodactylus klugei and Hemidactylus brasilianus) families in a semiarid region of Brazil. Six nematode species were identified: Parapharyngodon alvarengai and Spauligodon oxkutzcabiensis (Pharyngodonidae), Physaloptera lutzi (Physalopteridae), Skrjabinelazia intermedia (Seuratidae), Trichospirura sp. (Rhabdochonidae) and Piratuba sp. (Onchocercidae), and a cestode species, Oochoristica sp. (Linstowiidae). The most prevalent species were Spauligodon oxkutzcabiensis, which infected P. pollicaris (75%), and Parapharyngodon alvarengai, which infected G. geckoides (29%). South American lizards were identified as being new hosts for the Trichospirura genus (a usual parasite of mammals), and there were 16 new occurrences of parasite species in the five lizard species studied herein.

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.
