The effects of incremental maxillomandibular advancement surgery on airway morphology: a cadaveric study.

Evidence demonstrates efficacy of maxillomandibular advancement (MMA) treatment of obstructive sleep apnea (OSA) and airway expansion. Patient studies are limited to pre/post-surgery comparisons. This cadaveric study evaluated intra-individual relationships between magnitudes of MMA advancement and airway changes.

Experimental investigation and molecular simulations of quinone related compounds as COX/LOX inhibitors.

Quinone-containing compounds have risen as promising anti-inflammatory targets; however, very little research has been directed to investigate their potentials. Accordingly, the current study aimed to design and synthesize group of quinones bearing different substituents to investigate the effect of these functionalities on the anti-inflammatory activities of this important scaffold. The choice of these substituents was carefully done, varying from a directly attached heterocyclic ring to different aromatic moieties linked through a nitrogen spacer.

Molecular Mechanics Simulations and Experimental Investigation of the Effect of Tadalafil on Various Inflammatory Pain Mediators.

Purpose: Tadalafil's exact analgesic mechanism is still unclear. The current study aimed to elucidate this mechanism in an inflammatory pain model.

Methods: Computer-assisted simulation docking experiments were carried out to assess the binding of tadalafil to different ligands.

Structure-guided approach on the role of substitution on amide-linked bipyrazoles and its effect on their anti-inflammatory activity.

A structure-guided modelling approach using COX-2 as a template was used to investigate the effect of replacing the chloro atom located at the chlorophenyl ring of amide-linked bipyrazole moieties, aiming at attaining better anti-inflammatory effect with a good safety profile. Bromo, fluoro, nitro, and methyl groups were revealed to be ideal candidates. Consequently, new bipyrazole derivatives were synthesised.
