ABNORMAL RESPONSES TO BARBITURATES *

Abnormal responses to rubella infection.

Two cases of rubella are described which caused initial problems in laboratory diagnosis due to abnormal features in the immune response. One patient presented with thrombocytopenic purpura and associated circulating immune complexes. The other patient, who was in early pregnancy, had an unusually prolonged rash and a delayed humoral immune response. The possible reasons for the difficulties in...

Barbiturates.

Comparative depression of several short acting barbiturates and spiro-barbiturates.

In an effort to develop new and possibly better types of barbiturates, suitable for intravenous use, a large number of spiro-barbiturates have been prepared by a ring closure on the 5-carbon atom of the barbituric acid and afforded for pharmacologic study. Spiro(2'-ethyl-3',5'-dimethyl cyclopentane) thio-barbituric acid appears to be the most promising product of a series of 50 analogues. Stoel...

Abnormal Ergosterol Biosynthesis Activates Transcriptional Responses to Antifungal Azoles

Fungi transcriptionally upregulate expression of azole efflux pumps and ergosterol biosynthesis pathway genes when exposed to antifungal agents that target ergosterol biosynthesis. To date, these transcriptional responses have been shown to be dependent on the presence of the azoles and/or depletion of ergosterol. Using an inducible promoter to regulate Neurospora crassa erg11, which encodes th...

Abnormal cortical responses to somatosensory stimulation in medication-overuse headache

BACKGROUND Medication-overuse headache (MOH) is a frequent, disabling disorder. Despite a controversial pathophysiology convincing evidence attributes a pivotal role to central sensitization. Most patients with MOH initially have episodic migraine without aura (MOA) characterized interictally by an absent amplitude decrease in cortical evoked potentials to repetitive stimuli (habituation defici...
