Life Design Counseling: A study on client's operations for meaning construction

This study evaluates the adequacy of the micro-theory of client operations to explain meaning construction in Life Design Counseling. Four adolescents were interviewed on their second counseling session. Their recollections were stimulated through the replay of counseling videotapes and the resulting transcribed interviews were qualitatively analyzed. Results confirmed a sequence of client operations evolving from the symbolic representation of experience and reflexive self-examination towards making new realizations and revisioning self. Moreover, clients reported negative and positive session moments evidencing that clients’ attention and activity during the session was not restricted to meaning construction operations. Practical implications for life design counseling are derived from the results and discussed.

Design, Synthesis and Bioassays of 3-substituted-3-hydroxyoxindoles for cholinesterase inhibition

Based on the positive bioassay results of the known oxindole hit compound rac-1-benzyl-3-hydroxy-3-phenylindolin-2-one which showed significant inhibition of butyrylcholinesterase (BuChE) (IC50=7.41 μM), a library of 31 analogues of 3-substituted-3-hydroxyoxindoles was synthesized and screened for both acetylcholinesterase (AChE) and BuChE activity. Our bioassays revealed that some of the new compounds exhibited moderate inhibition of eel AChE (EeAChE) and very good inhibition of equine serum BuChE (EqBuChE) with a best IC50 of 1.02 μM. On the basis of these results, the lead compound 1-((1-benzylpiperidin-4-yl)methyl)-3-hydroxy-3-phenylindolin-2-one was designed, which was shown to interact well with the enzymes active sites by molecular docking, was synthesized and upon bioassay gave an IC50 of 6.61 μM for BuChE. Interestingly, when we separated rac-benzyl-3-hydroxy-3-phenylindolin-2-one into the individual enantiomers (R)- and (S)-benzyl-3-hydroxy-3-phenylindolin-2-one it was the latter enantiomer that gave the best IC50 of 6.19 μM for BuChE.
