Eficácia de carrapaticidas em rebanhos leiteiros de Rondônia.

O carrapato dos bovinos, Rhipicephalus microplus é um dos principais problemas sanitários dos rebanhos leiteiros em Rondônia. As condições climáticas do Estado são propícias ao desenvolvimento biológico do carrapato, representando um desafio à pecuária leiteira, uma vez que os bovinos estão permanente expostos à infestação por carrapato. Esta publicação reúne informações a respeito do controle deste ácaro.bitstream/item/33600/1/ct113-carrapaticidas.pd

Expression of E-cadherin, Snail and Hakai in epithelial cells isolated from the primary tumor and from peritumoral tissue of invasive ductal breast carcinomas

Epithelial intercellular cohesion, mainly mediated by E-cadherin (CDH1) expression and function, may be deregulated during cancer cell invasion of adjacent tissues and lymphatic and vascular channels. CDH1 expression is down-modulated in invasive lobular breast carcinomas but its regulation in invasive ductal carcinomas (IDC) is less clear. CDH1 expression is repressed by transcription factors such as Snail (SNAI1) and its product is degraded after Hakai ubiquitination. We compared CDH1, SNAI1 and HAKAI mRNA expression in IDC and paired adjacent normal breast tissue and evaluated its relation with node metastasis and circulating tumor cells. Matched tumor/peritumoral and blood samples were collected from 30 patients with early IDC. Epithelial cells from each compartment (tumor/peritumoral) were recovered by an immunomagnetic method and gene expression was determined by real time RT-PCR. There were no differences in CDH1, SNAI1 and HAKAI mRNA expression between tumor and corresponding peritumoral samples and no differential tumoral gene expression according to nodal involvement. Another 30 patients with a long-term follow-up (at least 5 years) and a differential prognosis (good or poor, as defined by breast cancer death) had E-cadherin and Snail protein detected by immunohistochemistry in tumor samples. In this group, E-cadherin-positive expression, but not Snail, may be associated with a better prognosis. This is the first report simultaneously analyzing CDH1, SNAI1 and HAKAI mRNA expression in matched tumor and peritumoral samples from patients with IDC. However, no clear pattern of their expression could distinguish the invasive tumor compartment from its adjacent normal tissue.FAPESPCoordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES

The Camamu Basin Offshore Environmental Monitoring through Remote Sensing

In this paper, multispectral remote sensing data from MODIS-Aqua were used to caracterize the Camamu offshore basin and to monitor 6 production wells located in the Manati field, eastern Brazil, showing their great potential for environmental monitoring for the oil drilling and gas industries. Results were based on the interpretation of SST, Chlorophyll-a and K490 derived from the Aqua satellite passes on march 4th and july 12th, as well as, monthly time series for each of these geophysical parameters. SST values show an opposite behaviour when compared to Chlorophyll-a and K490, with the last two parameters changing one order of magnitude seasonally
