Density functional theory has been employed to study indolo[3,2,1-]carbazole donor-based dyes, incorporating one and two units of 2,4-dimethoxybenzene auxiliary donors. Electrostatic potential analysis highlights the dye with one auxiliary donor (D2) as having the highest charge-donating capability. Structural analysis shows that auxiliary donors enhance planarity, reduce steric hindrance, and improve π-conjugation.

Misdiagnosis of primary ITP occurs in patients with inherited thrombocytopenia and primary immunodeficiency syndromes. This study investigates whether genetic testing for inherited thrombocytopenia or primary immunodeficiency can enhance diagnostic accuracy in ITP, and guide treatment strategies.

Using laser temperature-jump (T-jump) spectroscopy combined with cytosine-analog Förster Resonance Energy Transfer (FRET) probes that sense local DNA conformations, we measured the intrinsic dynamics of DNA containing 3 base-pair mismatches recognized in vitro by Rad4 (yeast ortholog of XPC). Rad4/XPC recognizes diverse lesions from environmental mutagens and initiates nucleotide excision repair.
