FEBS Letters, EarlyView.Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

The challenges and limitations of vivianite quantification with 2,2′-bipyridine extraction
Science of The Total EnvironmentVivianite presents a significant phosphorus pool in iron-rich, reducing environments, necessitating the development of an affordable and routine quantification method. A novel extraction protocol using 2,2'-bipyridine (Bipy) was proposed as a promising approach.

The Limitations of Locus Specific Methylation Qualification and Quantification in Clinical Material [PDF]
Frontiers in Genetics, 2012 The terms methylation quantification and qualification seem self-explanatory however, the results of experiments aiming to quantify or qualify locus specific methylation in clinical material are often difficult to interpret. There are three main reasons for difficulties in understanding methylation status measurement.
