The use of complementary and alternative medicine by patients attending a UK headache clinic.

Objectives: This study was undertaken in order to determine the extent of the use of CAM in a UK headache clinic.

Design: Ninety-two patients attending a headache clinic were given a questionnaire containing questions regarding their headaches and their use of CAM for headaches.

Setting: Outpatient headache clinic, Birmingham, UK.

Evolution of the "OR37" subfamily of olfactory receptors: a cross-species comparison.

Genes encoding the olfactory receptors of the "OR37" subfamily of the mouse are characterized by special features including a clustered expression pattern, assembly in two distinct gene clusters, and highly conserved putative promoter motifs. Mining the rat and dog databases revealed that these two species possess highly conserved clusters of OR37 genes at two syntenic genomic loci. In a prototherian mammal, the platypus (Ornithorhynchus anatinus), none of the characteristic OR37 genes were found.

Mechanisms and significance of reduced activity and responsiveness in resting frog tadpoles.

Hatchling Xenopus laevis tadpoles spend most of their time attached to objects or the water surface by mucus secreted by a gland on the head. While attached, swimming activity and responsiveness to swim-initiating stimuli are reduced over long periods of time. We have investigated the mechanisms and significance of this apparent long-term inhibition.
