Synthesis of cytochalasan analogues with aryl substituents at position 10.

Cytochalasans are fungal metabolites that are known to inhibit actin polymerization. Despite their remarkable bioactivity, there are few studies on the structure-activity relationship (SAR) of the cytochalasan scaffold. The full potential of structural modifications remains largely unexplored.

Mulberry Posterior Inferior Nasal Turbinate Is Associated with a Lower Pharyngeal pH Environment.

Objectives: Mulberry-like changes of the posterior inferior nasal turbinate (MPINT) can lead to nasal obstruction. Extraesophageal reflux (EER) characterized by lower pH causes mucosal inflammation and therefore can contribute to sinonasal pathologies. No prior studies have objectively examined the possible association between acidic pH and MPINT formation.

Enantioseparation and a comprehensive spectroscopic analysis of novel synthetic cathinones laterally substituted with a trifluoromethyl group.

Recently, the number of structural modifications of synthetic cathinones has been growing making them the second largest group of new psychoactive substances in Europe. Although they are abused because of their various psychoactive effects, some compounds from this group also serve as pharmaceuticals. Since synthetic cathinones are chiral molecules with one chiral center, their biological, toxicological, and pharmacological properties may significantly differ according to their absolute configuration and enantiomeric excess.

Association Between Inferior Turbinate Hypertrophy and Extraesophageal Reflux.

Importance: To the authors' knowledge, no prior studies have examined the association between inferior turbinate hypertrophy (ITH) and extraesophageal reflux (EER). If EER were a cause or cofactor of ITH, antireflux treatment can be considered prior to surgical intervention.

Objective: To evaluate EER presence and severity in patients with different degrees of ITH.
