['Awakening': a confusing improvement during treatment with atypical antipsychotic agents]. / 'Awakening': een verwarrende verbetering tijdens behandeling met atypische antipsychotica.

Two schizophrenic women, aged 30 and 40 years, respectively, in whom the symptoms changed after a switch in medication from clozapine to aripiprazole and from olanzapine followed by quetiapine to risperidone, respectively, were initially thought to be experiencing a possible recurrence. After thoughtful consideration, the phenomena, such as disappearance of drowsiness and of loss of energy, in combination with cognitive improvement, could be understood as the result of a dramatic improvement, known as 'awakening'. This had significant consequences for the follow-up since the patients had to deal with new possibilities and emotions.

Cellular and secretory proteins of the salivary glands of Sciara coprophila during the larval-pupal transformation.

The cellular and secretory proteins of the salivary gland of Sciara coprophila during the stages of the larval-pupal transformation were examined by electrophoresis in 0.6 mm sheets of polyacrylamide gel with both SDS-continuous and discontinuous buffer systems. After SDS-electrophoresis, all electrophoretograms of both reduced and nonreduced proteins from single glands stained with Coomassie brilliant blue revealed a pattern containing the same 25 bands during the stages of the larval-pupal transformation. With the staining procedures used in this study, qualitative increases and decreases were detected in existing proteins and enzymes. There was no evidence, however, for the appearance of new protein species that could be correlated with the onset of either pupation or gland histolysis. Electrophoretograms of reduced samples of anterior versus posterior gland parts indicated that no protein in the basic pattern of 25 bands was unique to either the anterior or posterior gland part. Electrophoretograms of reduced samples of secretion collected from either actively feeding or "cocoon"-building animals showed an electrophoretic pattern containing up to six of the 25 protein fractions detected in salivary gland samples, with varied amounts of these same six proteins in electrophoretograms of secretion samples from a given stage. Zymograms of non-specific esterases in salivary gland samples revealed a progressive increase in the amount of esterase reaction produce in one major band and some decrease in the second major band during later stages of the larval-pupal transformation.
