Investigation of Real-Time Photorepair Activity on DNA via Surface Plasmon Resonance

Kizilel, Riza; Demir, Enis; Azizoglu, Selimcan; Asimgi, Hande; Kavakli, Ibrahim Halil; Kizilel, Seda

The cyclobutane pyrimidine dimer (CPD) and 6-4 lesion formations along with the specific breaks on strands are the most common type of DNA damage caused by Ultraviolet light (UV) irradiation. CPD photolyase I and II construct two subfamilies of flavoproteins, which have recognition and repair...

Kinetics of anthocyanin degradation and polymeric colour formation in black carrot juice concentrates during storage

Turkyilmaz, Meltem; Ozkan, Mehmet

The changes in anthocyanins (ACNs) and polymeric colour of black carrot juice concentrate (BCJC) samples were monitored during storage at -23, 5 and 20 degrees C for 319 days and at 30 degrees C for 53 days. While ACN degradation was fitted to a first-order reaction model, polymeric colour...
