We are proud to announce that our esteemed colleague, Ayşe Nur AYDIN, has successfully defended her Ph.D. thesis titled "Determination of the Effects of Gadolinium at Different Temperatures on Zebrafish Using Biomarkers". We sincerely congratulate her on this important academic achievement and wish her continued success in her scientific career.

Her thesis work was conducted under the supervision of Prof. Dr. Rahmi Aydın and Assoc. Prof. Dr. Osman Serdar. The study investigated the effects of gadolinium on zebrafish (Danio rerio) at various temperatures, utilizing biomarkers to reveal detailed biological responses.

The results of this research were presented at an international symposium through the study titled "Gadolinium Range Determination Tests in Danio rerio Individuals at Different Temperatures." In addition, a scientific article entitled "Genotoxic and Oxidative Stress Effect of Gadolinium on Zebrafish at Different Temperatures" has been prepared and submitted for publication in a peer-reviewed SCI-indexed journal.

We once again extend our heartfelt congratulations to Ayşe Nur AYDIN for her dedication, scientific contributions, and outstanding success, and we wish her all the best in her future endeavors.
