Corne d’abondance

La société Hi-bred International du Zimbabwe a mis au point deux nouvelles variétés de maïs capables de résister à la redoutable maladie des taches grises. Des tests conduits dans de petites et grandes exploitations ont confirmé le rendement élevé de ces variétés (9 à 11t/ha), qui peuvent être transformées localement et ne nécessitent pas plus d’engrais que les autres variétés. Elles sont distribuées au Malawi par Chemicals and Marketing Malawi Limited qui organise des démonstrations.La société Hi-bred International du Zimbabwe a mis au point deux nouvelles variétés de maïs capables de résister à la redoutable maladie des taches grises.

Renal hemodynamics and renal function after catheter-based renal sympathetic denervation in patients with resistant hypertension

Increased renal resistive index and urinary albumin excretion are markers of hypertensive end-organ damage and renal vasoconstriction involving increased sympathetic activity. Catheter-based sympathetic renal denervation (RD) offers a new approach to reduce renal sympathetic activity and blood pressure in resistant hypertension. The influence of RD on renal hemodynamics, renal function, and urinary albumin excretion has not been studied. One hundred consecutive patients with resistant hypertension were included in the study; 88 underwent interventional RD and 12 served as controls. Systolic, diastolic, and pulse pressure, as well renal resistive index in interlobar arteries, renal function, and urinary albumin excretion, were measured before and at 3 and 6 months of follow-up. RD reduced systolic, diastolic, and pulse pressure at 3 and 6 months by 22.7/26.6 mm Hg, 7.7/9.7 mm Hg, and 15.1/17.5 mm Hg (P for all <0.001), respectively, without significant changes in the control group. SBP reduction after 6 months correlated with SBP baseline values (r=−0.46; P<0.001). There were no renal artery stenoses, dissections, or aneurysms during 6 months of follow-up. Renal resistive index decreased from 0.691±0.01 at baseline to 0.674±0.01 and 0.670±0.01 (P=0.037/0.017) at 3- and 6-month follow-up. Mean cystatin C glomerular filtration rate and urinary albumin excretion remained unchanged after RD; however, the number of patients with microalbuminuria or macroalbuminuria decreased. RD reduced blood pressure, renal resistive index, and incidence of albuminuria without adversely affecting glomerular filtration rate or renal artery structure within 6 months and appears to be a safe and effective therapeutic approach to lower blood pressure in patients with resistant hypertension.Felix Mahfoud, Bodo Cremers, Julia Janker, Britta Link, Oliver Vonend, Christian Ukena, Dominik Linz, Roland Schmieder, Lars Christian Rump, Ingrid Kindermann, Paul Andrew Sobotka, Henry Krum, Bruno Scheller, Markus Schlaich, Ulrich Laufs, Michael Böh

2-nucleon, 3-nucleon and 4-nucleon Transfer, Doorways To Fusion

Near-barrier differential cross sections of the prominent transfer channels in the systems S-33, Zr-90, Zr-91, Zr-93 and S-32 , Ru-100, Ru-101 have been measured including Q-distributions. The relatively large 2-,3- and 4-nucleon transfer cross sections suggest their contribution to the observed fusion enhancements. The angular distributions are discussed within the frame work of a simple semiclassical formalism and some interesting connections to fusion are revealed
