The DNA base excision repair pathway is responsible for removal of oxidative and endogenous DNA base damage in both prokaryotes and eukaryotes. This pathway involves formation of an apurinic/apyrimidinic (AP) site in the DNA, which is further processed to restore the integrity of the DNA. In Escherichia coli it has been suggested that the major mode of repair involves replacement of a single nu...

A comparison between 2 dilute citrate solutions (15mmol/l vs 18 mmol/l) in continuous renal replacement therapy: the base excess and renal replacement solution (BEARRS) study

Regional citrate anticoagulation (RCA) is a valid anticoagulation method in continuous renal replacement therapies (CRRT) and different combination of citrate and CRRT solutions can affect acid-base balance. Regardless of the anticoagulation protocol, hypophosphatemia occurs frequently in CRRT. In this case report, we evaluated safety and effects on acid-base balance of a new RCA- continuous ve...

ASTM F-75 Cobalt-base alloy castings are widely used for manufacturing orthopedic implants. This alloy needs both homogenization and solutionizing heat treatment after casting, as well as bioactivation of the surface to increase the ability of tissue bonding. In this study, ASTM F-75 Cobalt-base substrate was heat treated at 1220°C for 1 hour in contact with Hydroxyapatite-Bioglass powder in or...

The motif1-hairpin (M1H), located on (-)-strands of Turnip Crinkle Virus (TCV)-associated satellite RNA C (satC), is a replication enhancer and recombination hotspot. Results of in vivo genetic selection (SELEX: systematic evolution of ligands by exponential enrichment), where 28 bases of the M1H were randomized and then subjected to selection in plants, revealed that most winners contained one...
