Inhibition of Ras/ERK1/2 signaling protects against postischemic renal injuryMassimo Sabbatini
University Magna Graecia of Catanzaro, Italy
Am J Physiol Renal Physiol 290:F1408-15. 2006..These data demonstrate that inhibition of farnesylation and consequently of Ras/ERK1/2 signaling significantly reduces acute postischemic renal injury...
Arginase inhibition slows the progression of renal failure in rats with renal ablationMassimo Sabbatini
Departments of Nephrology and Experimental Medicine, University Federico II, 80131 Naples, Italy
Am J Physiol Renal Physiol 284:F680-7. 2003..Inhibition of arginase slows the progression of CRF in remnant rats similarly to arginine-treated rats; the better histological protection in MNF rats, however, suggests that additional factors are involved in these modifications...
Central acute D2 stimulation worsens bladder function in patients with mild Parkinson's diseaseLivia Brusa
Department of Neurology, University of Rome Tor Vergata, Rome, Italy
J Urol 175:202-6; discussion 206-7. 2006..CONCLUSIONS: According to our results, a central acute D2 stimulation seems to be responsible of a reduction of bladder capacity with worsening of detrusor overactivity in patients with mild PD...
