Diferenças regionais do cultivo de café no Brasil

Brazil is one of the major coffee producers in the world, because of this, the goal of this study was to assess the regional differences of coffee cultivation for the reference crops 2001/2002 and 2002/03 by means of a life cycle assessment (LCA) in order to generate detailed production inventory data as well as quantify the potential environmental impacts of this crop. All information considered in this study (use of water, fossil based energy, fertilizers, pesticides and correctives) was taken from data collected from the producing farms. Four Brazilian coffee producer regions located at the Southeastern region were evaluated: Sul de Minas Gerais and Cerrado Mineiro in Minas Gerais State, and Mogiana and Alta Paulista regions in São Paulo State. The data refer to a production of 25.2 million kg of green coffee. Depending on the considered region, the production of 1,000 kg of green coffee requires, on average, approx. 9,300 to 13,000 kg of total energy, 70 to 130 kg of diesel, 6,500 to 12,700 kg of process water, 270 to 340 kg of fertilizers (NPK), 2.0 to 13.0 kg of pesticides, 230 to 600 kg of correctives, and yield around 1,600 to 1,900 kg/ha. Despite 20% of the coffee growers showing a good environmental performance, i.e. consumption of pesticides, fertilizers and correctives lower than the regional averages, this study has also identified some farms that can probably reduce the amount of some inputs and enhance their environmental performance.

Congelação de espermatozoides epididimários de gatos utilizando o diluidor Botu-crio® após refrigeração por 24 h em contêiner de transporte de sêmen Botu-tainer®

The possibilities of using the sperm collected from the epididymis have been widely used because the fertilizing capacity sperm preservation and the possibility of using it for wild cats. But in the process of cryopreservation, some studies show a decrease in the quality of the sperm when left under cooling before frozen for some time. This study aimed to assess the quality of the epididymal sperm obtained from domestic cats after cryopreservation using a diluent based on egg yolk and glycerol (Botu-crio®), comparing the morphofunctional characteristics after cooling for 24 hours in a container of semen transport (Botu-tainer®). We use eight cats submitted to elective orchiectomy, aging from eight months, without racial determination, and good nutritional status. These sperm characteristics were: motility, vigor, concentration, membrane integrity and morphology. It has been found, after statistical analysis, that the container of semen was able to maintain sperm viability, even for 24h. We also observed a significant decrease on all parameters after frozen, consequential, probably to thermal stress that occurs in processing. However, the percentage of membrane integrity after thawing shows good employability of the Botu-crio®, which viability is possible to perform in vitro fertilization, requiring higher ratings.

Dinâmica da produção de serapilheira em diferentes sistemas de restauração florestal

The ecological restoration is an alternative to increasingly important for biodiversity conservation. However, actions need indicators to evaluate its effectiveness in restablishment ecological processes, including nutrient cycling. The objective of this study was to compare the annual litterfall from five different treatments for forest restoration, compared with a neighboring fragment of Seasonal Semideciduous Forest, in order to subsidize their management plans for ecological restoration. Litter traps of 0.25m² were used, and a total production was: 1700.6 Kg. ha-1.year-1(treatment 1), 7748.1 Kg. ha-1.year-1(treatment 2), 7120.8 Kg. ha-1.year-1 (treatment 3), 9254.5 Kg. ha- 1.year-1 (treatment 4), 7130.2 Kg. ha-1.year-1 (treatment 5) and 8876 Kg. ha-1.year-1 (fragment of Seasonal Semideciduous Forest - treatment 6). The leaf fraction was the largest contributor to the deposition of litter in all treatments. Litter served as a good environmental indicator that can be used as a tool to support management plans. Key words: Litterfall, forest restoration and Seasonal Semideciduous Forest

Diagnóstico de potenciliade das unidades ambientais na bacia do Rio Capivara, Botucatu - SP

This work has the objective to elaborate the potentialities of the farming expand diagnosis of the Capivara River Hydrographic basin, in the Botucatu – SP municipal district, to obtain an interpretation of the system actual situation through the historical trajectory and possible evolution with the assistance of the SIG Ilwis 3.4 and orbital images CBERS 2B, in the pancromatics bands, obtained in 12/07/2008. The potentialities of the farming expand diagnosis was obtained through the physical mean modeling, of the farming expand presents in the studied environment and shows possible line actions to minimize the impacts e reach a sustainable development to the region. The Capivara river basin presents more than 70% of your areas occupied by the anthropic expanding, with the extensive farming predominance, forestall planting, orange and sugar cane. In the potentiality diagnostic analyses notes the good quality of the basin to the farming expand, except the region comprehended by the Botucatu Cuesta and the meadows area. The basin until has a good environmental quality and this diagnosis must serve for a start point to the realization of the territorial ordination as quick as possible to the environment conditions finds remains the same, granting the recovery capability.

Struttura dei popolamenti meiobentonici nella zona intertidale dell'Alto Adriatico a differenti gradi di antropizzazione

The present work is part of the European project THESEUS (Innovative technologies for safer Europeans coasts in a changing climate). The main goals are to provide adequate integrated methodologies for strategic planning of sustainable coastal defence. The present study investigates the structure and composition of meiobenthonic populations of the intertidal zone in four beaches along the Northern Adriatic coast of Emilia Romagna: Lido di Spina, Bellocchio, Lido di Dante e Cervia. The four sites are different for the level of human impacts and for the different management interventions against coastal erosion. The analysis of biotic and abiotic variables revealed different responses due mainly to site-specific characteristics of the investigated sites, in particular as regards the site of Bellocchio. The growing interest in ecosystems of sandy beaches has recently highlighted the importance of the ecological role of meiofauna, emphasizing the need to develop studies aimed to conservation as well as to the use of these organisms as descriptors of the environmental status. The present study showed that the response of the organisms of meiofauna was highly sensitive to the specific environmental conditions of the four sites considered. Therefore it appears to be possible to consider the response of meiofauna to environmental and anthropogenic stressors as supplementary information to the responses of macrobenthic communities, which have been, until now, widely recognized and used as syncretic indicators of the ecosystem status.

Treatment of advanced soft-tissue sarcomas using a combined strategy of high-dose ifosfamide, high-dose doxorubicin and salvage therapies

Having determined in a phase I study the maximum tolerated dose of high-dose ifosfamide combined with high-dose doxorubicin, we now report the long-term results of a phase II trial in advanced soft-tissue sarcomas. Forty-six patients with locally advanced or metastatic soft-tissue sarcomas were included, with age <60 years and all except one in good performance status (0 or 1). The chemotherapy treatment consisted of ifosfamide 10 g m(-2) (continuous infusion for 5 days), doxorubicin 30 mg m(-2) day(-1) x 3 (total dose 90 mg m(-2)), mesna and granulocyte-colony stimulating factor. Cycles were repeated every 21 days. A median of 4 (1-6) cycles per patient was administered. Twenty-two patients responded to therapy, including three complete responders and 19 partial responders for an overall response rate of 48% (95% CI: 33-63%). The response rate was not different between localised and metastatic diseases or between histological types, but was higher in grade 3 tumours. Median overall survival was 19 months. Salvage therapies (surgery and/or radiotherapy) were performed in 43% of patients and found to be the most significant predictor for favourable survival (exploratory multivariate analysis). Haematological toxicity was severe, including grade > or =3 neutropenia in 59%, thrombopenia in 39% and anaemia in 27% of cycles. Three patients experienced grade 3 neurotoxicity and one patient died of septic shock. This high-dose regimen is toxic but nonetheless feasible in multicentre settings in non elderly patients with good performance status. A high response rate was obtained. Prolonged survival was mainly a function of salvage therapies.

Adding cetuximab to capecitabine plus oxaliplatin (XELOX) in first-line treatment of metastatic colorectal cancer: a randomized phase II trial of the Swiss Group for Clinical Cancer Research SAKK

BACKGROUND: To determine the activity and tolerability of adding cetuximab to the oxaliplatin and capecitabine (XELOX) combination in first-line treatment of metastatic colorectal cancer (MCC). PATIENTS AND METHODS: In a multicenter two-arm phase II trial, patients were randomized to receive oxaliplatin 130 mg/m(2) on day 1 and capecitabine 1000 mg/m(2) twice daily on days 1-14 every 3 weeks alone or in combination with standard dose cetuximab. Treatment was limited to a maximum of six cycles. RESULTS: Seventy-four patients with good performance status entered the trial. Objective partial response rates after external review and radiological confirmation were 14% and 41% in the XELOX and in the XELOX + Cetuximab arm, respectively. Stable disease has been observed in 62% and 35% of the patients, with 76% disease control in both arms. Cetuximab led to skin rash in 65% of the patients. The median overall survival was 16.5 months for arm A and 20.5 months for arm B. The median time to progression was 5.8 months for arm A and 7.2 months for arm B. CONCLUSION: Differences in response rates between the treatment arms indicate that cetuximab may improve outcome with XELOX. The correct place of the cetuximab, oxaliplatin and fluoropyrimidine combinations in first-line treatment of MCC has to be assessed in phase III trials.
