Over the course of a few decades, soybeans in Brazil evolved from being a localized crop, with planting suitable only in regions with long photoperiods, to being the most cultivated crop countrywide. This happened thanks to the development of varieties that allowed changes in the planting calendar, permitting both cultivation in lower latitudes and the adoption of modern double-cropping systems. Here we develop a spatial dataset of Brazilian soy planting-window estimates for rainfed single and double ...

Background Recent studies demonstrate that interstitial inorganic phosphate is significantly elevated in the breast cancer microenvironment as compared to normal tissue. In addition it has been shown that breast cancer cells express high levels of the NaPi-IIb carrier (SLC34A2), suggesting that this carrier may play a role in breast cancer progression. However, the biochemical behavior of inorganic phosphate (Pi) transporter in this cancer type remains elusive. Methods In this work, we characterize ...

Abstract The physical hydroclimate system of the Amazon functions on several spatial and temporal scales. Large-scale processes control the main seasonal patterns of atmospheric circulation and rainfall. Seasonal variability in solar forcing, associated with the low rainforest albedo, provides energy for continental heating, convection, and the onset of the South American monsoon. Mesoscale processes cause localized circulations such as river breeze and deforestation breeze. We assessed the impact ...

Snake venom serine proteases (SVSPs) are enzymes that are capable of interfering in various parts of the blood coagulation cascade, which makes them interesting candidates for the development of new therapeutic drugs. Herein, we isolated and characterized Moojase, a potent coagulant enzyme from Bothrops moojeni snake venom. The toxin was isolated from the crude venom using a two-step chromatographic procedure. Moojase is a glycoprotein with N-linked glycans, molecular mass of 30.3 kDa and acidic ...

The objective of this study was to evaluate the effect of ischemic preconditioning upon lesions produced by ischemia-reperfusion of the small intestine. Thirty EPM-1 Wistar rats were randomly distributed into three groups: ischemic preconditioning (IPC; n = 12), ischemia-reperfusion (I/R; n = 12), and control (C; n = 6). Laparotomy permitted isolation of the mesenteric artery for clamping. The animals were heparinized and hydrated. IPC was induced by: 10 minutes of ischemia followed by 10 minutes of reperfusion ...
