Si incentiva l'inutile (elettrodomestici, nautica, fotovoltaico, auto), ma quale vantaggio avrebbe invece un piano di salute pubblica che migliora le capacita' produttive e di lavoro della popolazione oltre i 60 anni? un tre-4 giorni di lavoro in piu' all'anno quanto fanno per lo Stato?
ovviamente e' un modo di pensare fuori dalla realta'....

Background
Hypertension is a frequent co-morbidity in patients with osteoarthritis (OA) (Singh et al, 2002). Non steroidal anti-inflammatory drugs (NSAIDs) are the mainstay treatment of OA; however, their long term use may increase blood pressure, likely by inhibiting cyclooxygenase (COX)-derived prostanoids in the vascular bed (Antman et al, 2007). Endothelium-derived vasodil...

Methods
Human internal mammary artery (hIMA) specimens from patients undergoing coronary artery bypass grafting (CABG) were prepared as rings and mounted for the measurement of isometric tone. Response of KCl-precontracted rings to acetylcholine (ACh, 10 mM) or sodium nitroprusside (SNP, 1 mM) was assessed. After wash-out, KCl-precontracted arteries were exposed to naproxcinod or naproxen...

Results
In pre-contracted hIMA, endothelium-dependent vasorelaxation (acetylcholine) was reduced in comparison to the endothelium-independent (sodium nitroprusside) response. Accordingly, electron microscopy showed cellular abnormalities such as intima hyperplasia and endothelial cell degeneration. Naproxcinod (10 nM - 100 mM) caused a NO-mediated concentration-dependent relaxation (Emax= -52.4±6.9%,...

Conclusions
Cyclooxygenase inhibition in arteries with endothelial dysfunction results in vasoconstriction, suggesting an important role of COX-derived prostaglandins (likely from COX-2) in the regulation and maintenance of vascular tone. Nitric oxide donation from naproxcinod suppresses the vasoconstricting effect due to COX inhibition. In cardiovascular diseases accompanied by en...
