Acid/Base-Co-catalyzed Formal Baeyer-Villiger Oxidation Reaction of Ketones: Using Molecular Oxygen as the Oxidant.

A novel acid/base-co-catalyzed formal Baeyer-Villiger oxidation of various ketones using O as the sole oxidant under metal-free conditions has been developed for the first time. The reaction tolerates a wide range of ketones and anilines and provides a simple and efficient method for the construction of various amides and isoquinolin-1-ones from the reactions of ketones with anilines in a single step.

Blood pressure and heart rate adjustment following acute Frenkel's ambulatory exercise in chronic hemiparetics stroke survivors: a comparative study.

Background: Frenkel's ambulatory activity has been routinely employed by physiotherapists for rehabilitation of gait coordination, however, its immediate influence on blood pressure and heart rate has not been investigated.

Objective: To investigate the acute effect of Frenkel's ambulatory activity on blood pressure and heart rate of chronic hemiparetic stroke survivors.

Method: Using a comparative study design, 60 chronic hemiparetic stroke survivors of varying onset of stroke, ≤6, >6-11 and ≥12 months were subjected to a 2-minute Frenkel's ambulatory activity on marked footsteps (from standard adult described footsteps).
