Do renal failure and hemodialysis have any effect on the elimination of free and total prostate-specific antigen?
The limited kidney reserve in patients with end-stage renal disease is sufficient to maintain the levels of t-PSA and f-PSA within normal ranges and hemodialysis does not alter the serum levels of different PSA forms.
The profound stereo-selective antihypertensive effect of L-serine is neither mediated nor mimicked by glycine. It does not require N-methyl D-aspartate receptor activation by glycine but likely involves activation of endothelial KCa channels. L-Serine is a potential antihypertensive agent.
