Abstract: based on field observations and pitfall sampling, we determined the species richness, relative abundance, and reproductive habitat of terrestrial frogs in three municipalities in the triangulo mineiro region, south cerrado biome, in southeastern brazil. we found thirty-two species of terrestrial frogs, belonging to the families brachycephalidae, bufonidae, cycloramphidae, dendrobatidae, leiuperidae, leptodactylidae and microhylidae. most of the species were found in open areas and reproduced in human-generated environments, such as artificial lakes (10 species) and ponds (14 species). dominance was high, with physalaemus cuvieri fitzinger, 1826 (leiuperidae) representing 48% of sampled frogs. a larger number of individuals was captured in the wet season, when most of the species were reproducing. compared to other areas of cerrado biome, the triangulo mineiro sites presented a larger number of species, which may be attributed to the larger sampled area and greater sampling effort, lower altitude and presence of human generated habitats. the richness of terrestrial frogs was also larger than that in some forested localities in southeastern brazil, indicating that the number of species cannot be explained only by precipitation and type of vegetation cover. the greater abundance of individuals during the wet season may be related to a greater movement of adults to breeding sites and to juvenile recruitment/dispersion. the heterogeneity of environments in the cerrado biome, including its several isolated highlands, contributes to its high (local and regional) diversity of frogs.

Abstract: background and objectives: cardiac output and preload as absolute data do not offer helpful information about the hemodynamic of critically ill patients. however, monitoring the response of these variables to volume challenge or inotropic drugs is a very useful tool in the critical care setting, particularly for patients with signs of tissue hypoperfusion. although pac remains the " gold standard" to measure cardiac output and preload, new and alternative technologies were developed to evaluate these hemodynamic variables. methods: modified delphi methodology was used to create and quantify the consensus between the participants. amib indicated a coordinator who invited more six experts in the area of monitoring and hemodynamic support to constitute the consensus advisory board. twenty three physician and two nurses selected from different regions of the country completed the expert panel, which reviewed the pertinent bibliography listed at the medline in the period from 1996 to 2004. results: recommendations regarding the use of arterial pulse pressure variation during mechanical ventilation, continuous arterial pulse contour and lithium dilution cardiac output measurements, esophageal doppler waveform, thoracic electrical bioimpedance, echocardiography and partial co2 rebreathing for monitoring cardiac output and preload were created. conclusions: the new and less invasive techniques for the measurement of cardiac output, preload or fluid responsiveness are accurate and may be an alternative to pac in critically ill patients.

Abstract: the rectum is the second most common location of the carcinoid tumors of the gastrointestinal tract. it represents approximately one or two per cent of the rectal neoplasms. metastases are less frequent and it presents a better prognosis than carcinoid tumors found in the digestive tract. treatment is surgical and the technique to be used depends fundamentally on the size of the tumor and the degree of in the intestinal wall penetration. lesions which are greater than one centimeter have been treated with local excision, while the ones greater than two centimeters have been submitted to a radical resection. this article presents a case of rectal carcinoid diagnosed and treated initially as adenocarcinoma by abdominal rectossigmoidectomy. there were no signs of recurrence after a period of five years and six months of post-surgical follow-up. nowadays the validity of radical resection in the treatment of rectal carcinoids has been much questioned due to the fact that it has not shown a significant raise in survival rate when compared with patients who were submitted to a local resection.

Abstract: coffee is one of the most valuable agricultural commodities and ranks second on international trade exchanges. the genus coffea belongs to the rubiaceae family which includes other important plants. the genus contains about 100 species but commercial production is based only on two species, coffea arabica and coffea canephora that represent about 70 % and 30 % of the total coffee market, respectively. the brazilian coffee genome project was designed with the objective of making modern genomics resources available to the coffee scientific community, working on different aspects of the coffee production chain. we have single-pass sequenced a total of 214,964 randomly picked clones from 37 cdna libraries of c. arabica, c. canephora and c. racemosa, representing specific stages of cells and plant development that after trimming resulted in 130,792, 12,381 and 10,566 sequences for each species, respectively. the ests clustered into 17,982 clusters and 32,155 singletons. blast analysis of these sequences revealed that 22 % had no significant matches to sequences in the national center for biotechnology information database (of known or unknown function). the generated coffee est database resulted in the identification of close to 33,000 different unigenes. annotated sequencing results have been stored in an online database at http://www.lge.ibi.unicamp.br/cafe. resources developed in this project provide genetic and genomic tools that may hold the key to the sustainability, competitiveness and future viability of the coffee industry in local and international markets.

Abstract: The forage production in crop-livestock integration is critical both for formation of straw for no tillage planting and food for livestock farm. The experiment was conducted in the autumn/winter of 2009 and 2010, in the city of Selvíria -state of Mato Grosso do Sul -MS, Brazil, at Experimental Station of FEIS/UNESP. The objective was to evaluate the optimal depth for deposition of seeds of two Brachiaria species intercropped with corn with emphasis on grain yield and straw. The experimental design was a randomized block design in a factorial scheme 3 x 3, with four replications. The main treatments were two species of Brachiaria (Urochloa brizantha "Marandú" and Urochloa ruziziensis), which seeds were mixed with corn fertilizer and a control treatment (without intercropping). Secondary treatments consisted of three depths (8; 10 and 16 cm) in the deposition of fertilizer (in the consortium and the control treatments). The intercropping corn with Brachiaria produced similar amounts of straw. The straw total production was higher when intercropped and decreased with depth. The consortium with U. ruziziensis provided higher grain yield of corn in relation to U. brizantha, in 2010. The sowing depth of forages did not affect corn yield. A produ o de forragem na integra o lavoura-pecuária é de suma importancia, tanto para alimenta o animal como para forma o de palhada para plantio direto. O experimento foi conduzido no outono/inverno de 2009 e 2010, em Selvíria -MS, na Fazenda de Ensino, Pesquisa e Extens o da FEIS/UNESP. O objetivo foi avaliar a profundidade mais adequada para deposi o das sementes de duas espécies de braquiárias em consórcio com milho, com ênfase para a produtividade do milho e forma o de palha. O delineamento experimental foi em blocos ao acaso, em esquema fatorial 3 x 3, com quatro repeti es. Os tratamentos principais foram duas espécies de braquiárias (Urochloa brizantha cv. Marandú e Urochloa ruziziensis), cujas sementes foram misturadas ao fertilizante do milho, e um tratamento-testemunha (sem consórcio). Os tratamentos secundários constituíram-se em três profundidades (8; 10 e 16 cm) de deposi o do fertilizante (em consórcio e na testemunha). Os consórcios de milho com braquiária produziram quantidades de palha semelhantes. A produ o total de palha foi maior nos consórcios e nas menores profundidades. O consórcio com U. ruziziensis propiciou maior produtividade de gr os de milho em rela o ao com U. brizantha, em 2010. As profundidades de semeadura das forrageiras n o afetaram a produtividade de milho.
