Evaluation of the posterior reference point of ala tragus line in relation to occlusal plane and Frankfort horizontal plane through cephalometry in Sangareddy (Telangana) population [PDF]

, 2022
The Occlusal plane (OP) inclination is determined by paralleling the ala- tragus line to the occlusal plane. The location of the ala-tragus line is unclear because the exact location of the posterior reference tragal point is controversial. Additionally,

Intermolecular Carbon–Carbon Naphthalene Coupling Involves a Radical Mechanism Driven by Cytochrome P450 in Alternaria alternata

Angewandte Chemie, EarlyView.
1,8‐DHN is an important intermediate to form complex aromatic ring systems. Phenol‐coupling reactions are important for the dimerization of two molecules. Here, we show that a fungal cytochrome P450 enzyme catalyzes specific C─C bonds. ABSTRACT Dihydroxynaphthalene (DHN) derivatives are precursors of biologically important molecules, including melanin ...
