Molecular cloning and functional expression of the human glycine transporter GlyT2 and chromosomal localisation of the gene in the human genome.

Neurotransmitter transport systems are major targets for therapeutic alterations in synaptic function. We have cloned and sequenced a cDNA encoding the human type 2 glycine transporter GlyT2 from human brain and spinal cord. An open reading frame of 2391 nucleotides encodes a 797 amino acid protein that transports glycine in a Na+/Cl--dependent manner. When stably expressed in CHO cells, human GlyT2 displays a dose-dependent uptake of glycine with an apparent Km of 108 microM. This uptake is not affected by sarcosine at concentrations up to 1 mM. Radiation hybrid analysis mapped the GlyT2 gene to D11S1308 (LOD=8.988) on human chromosome 11p15.1-15.2.

Effects of magnetic resonance imaging on implantable permanent magnets.

Implantable permanent magnets are increasingly used in devices for otolaryngologic applications. It is likely that at least some of the patients with implanted magnets will be in need of magnetic resonance imaging (MRI). The effect of an MRI scan on the magnetic properties of implanted permanent magnets has not been previously demonstrated. Some of the basic concepts and descriptive terminology used in industry regarding permanent magnets are reviewed. Experiments presented show that the MRI scan is capable of demagnetizing permanent magnets. A case history is also presented that demonstrates demagnetizing of an implanted Audiant magnet by an MRI scan.

Short contact dithranol therapy: advantages of a stiff emulsifying ointment base.

In a single blind trial, 16 in-patients with psoriasis were treated with short contact dithranol in stiff Lassar's paste and in a stiff emulsifying ointment base of equivalent stiffness. The preparations were equally effective in clearing psoriasis and well tolerated. Perilesional treatment burns, reported with soft ointments, were not seen with the stiff emulsifying ointment preparation. Furthermore, unlike the paste, excess stiff emulsifying ointment can be removed by simply wiping with a moistened cloth, thus greatly facilitating home management of psoriasis.
