| The essential features of PMDD, according to DSM-IV, include markedly depressed mood, anxiety or tension, affective lability, and persistent anger or irritability. |
| Conversely, the possibility of intramolecular rearrangement means that failure to isolate geometric isomers or to resolve the racemic mixture into optical isomers is not absolute proof of lability. |
| Taube has interpreted lability of complexes according to their electronic configuration in terms of VB theory. |
| The zeolites are noted for their lability toward ion-exchange and reversible dehydration. |
| And this, in turn, may be regarded as but a manifestation of the process of survival by lability rather than by stability. |
| Mental disorders such as depression, anxiety, emotional lability, depersonalization, suicide attempts, and confusion were observed in this study. |
