We evaluated for reliability and reproducibility a semiquantitative gas-chromatographic assay of organic acids in samples of normal urine recovered from absorbent filter paper. We also evaluated this method for use in diagnosis of some of the more common organic acidurias. Transfer of urine from diapers to absorbent filter paper eases the usual trauma of specimen collection from young children;...

This clinical study evaluated the influence of scaling and root planning (SRP), with and without the use of tetracycline-loaded bovine absorbent membrane, in the reduction of periodontal pockets according to 3 parameters: probing pocket depth (PPD), bleeding on probing (BOP) and plaque index (PI). Twenty-four patients were selected totalizing 144 random teeth divided in 2 groups (n=72 teeth) - ...

BACKGROUND: Polyacrylamide is the main synthetic polymer used, and it absorbs water through the formation of hydrogen bonds. Super Absorbent Polymer (SAP) can absorb water up to 200-400 times its weight and increase its size by up to 100 times. OBJECTIVES: Evaluate effect of different irrigation regime and super absorbent polymer on agrop...
