| Efficient nitrogen (N) fertilizer management is critical for the economic production of maize (Zea mays L.) and the long-term protection of environmental quality. To study the effects of N doses and plant density on the N uptake and efficiency on forage maize cv. SC 704, an experiment was conducted in the Shahrekord region (32° 21' N, 50° 49' E; altitude 2050 m), Iran, at the Agricultural Research Station of Shahrekord University, during the 2007 growing season. The experiment was arranged with four plant densities (92 600, 104 200, 119 000 and 138 900 plants ha-1) and four nitrogen doses (200, 240, 280 and 320 kg ha-1) in a randomized complete block design with four replications. Increases of the plant density led to a significant N uptake in stalk, grain... |

| Angiotensin II (ANG II), the main effector of the renin-angiotensin system, is implicated in endothelial permeability, recruitment and activation of the immune cells, and also vascular remodeling through induction of inflammatory genes. Matrix metalloproteinases (MMPs) are considered to be important inflammatory factors. Elucidation of ANG II signaling pathways and of possible cross-talks between their components is essential for the development of efficient inhibitory medications. The current study investigates the inflammatory signaling pathways activated by ANG II in cultures of human monocytic U-937 cells, and the effects of specific pharmacological inhibitors of signaling intermediates on MMP-9 gene (MMP-9) expression and activity. MMP-9 expression... |
