Anurans Of The Municipality Of Barão De Monte Alto, State Of Minas Gerais, Southeastern Brazil

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)We present a list of the anuran amphibians from municipality of Barão de Monte Alto, state of Minas Gerais, southeastern Brazil. This region is part of the remaining Atlantic Forest and the studied environments are represented by forest patches and open habitats. We recorded 29 anuran species, many of these typical and/or endemic to the Atlantic Forest. None of the species registered was considered under threat of extinction in state, national or international red-lists. It is worth noting, however, the presence of the tree frogs Dendropsophus pseudomeridianus, the first record of this species in the state of Minas Gerais, and D. Bipunctatus, marking its expanded distribution in various locations of Minas Gerais. The present list examines zoogeography and conservation of anurans in the Brazilian southeast and broadens the knowledge of the anuran fauna in this region. © 2016 Check List and Authors.125CAPES, Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES

The Advertisement Calls and Distribution of Two Sympatric Species of \u3cem\u3eChiasmocleis\u3c/em\u3e (Méhely 1904) (Anura, Microhylidae, Gastrophryninae) from the Atlantic Forest

The advertisement calls of Chiasmocleis cordeiroi and C. crucis are described for populations from the municipalities of Igrapiúna and Camacan, respectively, state of Bahia, Brazil. Both calls consist of multipulsed notes produced in series. Differences between the two calls are: dominant frequency, higher in C. cordeiroi (range 4500-4898 Hz; C. crucis range 4069-4435 Hz); note rate, higher in C. cordeiroi (range 6.20--7.46 s/note; C. crucis range 5.17-5.59 s/note); pulse rate, higher in C. cordeiroi (151.82-194.83 s/note; C. crucis range 125.30- 142.12 s/note); and the structure of the modulation patterns of the notes. Moreover, the advertisement calls of C. crucis and C. cordeiroi are more similar than the calls of all syntopic congeners. Furthermore, the current distribution of both species was extended

New and conventional strategies for lung recruitment in acute respiratory distress syndrome

Mechanical ventilation is a supportive and life saving therapy in patients with acute lung injury (ALI)/acute respiratory distress syndrome (ARDS). Despite advances in critical care, mortality remains high. During the last decade, the fact that mechanical ventilation can produce morphologic and physiologic alterations in the lungs has been recognized. In this context, the use of low tidal volumes (VT) and limited inspiratory plateau pressure (Pplat) has been proposed when mechanically ventilating the lungs of patients with ALI/ARDS, to prevent lung as well as distal organ injury. However, the reduction in VT may result in alveolar derecruitment, cyclic opening and closing of atelectatic alveoli and distal small airways leading to ventilator-induced lung injury (VILI) if inadequate low positive end-expiratory pressure (PEEP) is applied. On the other hand, high PEEP levels may be associated with excessive lung parenchyma stress and strain and negative hemodynamic effects, resulting in systemic organ injury. Therefore, lung recruitment maneuvers have been proposed and used to open up collapsed lung, while PEEP counteracts alveolar derecruitment due to low VT ventilatio

Consumo de matéria seca e desempenho de novilhas das raças Girolando e Guzerá sob suplementação na caatinga, na época chuvosa, em Pernambuco, Brasil

Com os objetivos de estimar o consumo de matéria seca e avaliar a variação do peso vivo de novilhas, conduziu-se um experimento no período entre março e julho de 2003, com quatro estratégias de suplementação: sem suplementação (controle); torta de algodão (1 kg); palma-forrageira (10 kg); e de palma (5,0 kg) + torta de algodão (0,5 kg). O fornecimento de suplemento não influenciou o consumo de matéria seca (MS) do pasto nativo, no entanto afetou o consumo de MS total. O consumo de matéria seca total diferiu entre as raças, com valores de 5,44 e 6,75 kg/dia, respectivamente, para as raças Guzerá e Girolando. Nos animais sob suplementação com torta de algodão, o consumo de MS total foi superior ao do grupo controle (sem suplementação), porém semelhante ao daqueles sob suplementação com palma-forrageira e com torta de algodão + palma-forrageira. O ganho de peso vivo médio diário (de 517 e 434 g/animal, respectivamente, para os grupos Girolando e Guzerá) não diferiu entre as raças nem foi influenciado pela interação raça õ suplementação. Entre as estratégias de suplementação, no entanto, os valores tiveram diferença significativa e foram de 412, 620, 371 e 498 g/animal/dia, respectivamente, para os grupos controle e sob suplementação com torta de algodão; palma-forrageira; torta de algodão + palma-forrageira. No semiárido de Pernambuco, a suplementação com 1 kg de torta de algodão na época chuvosa do ano melhora o ganho de peso médio diário, independentemente da raça do animal
