During one decade, an increasing percentage of world population has to be attributed array environmental, health and lifestyle factors. The potential effect extremely low frequency electromagnetic fields (ELF-EMFs) emitted from electrical various devices in the occupational environment light at night (LAN) elicit biological response are a major concern for public scientists. Controversial genet...

1043 have been due to direct trauma or haematoma around an aberrantly coursing hypoglossal nerve, we still consider high puncture of the internal jugular vein to be a useful approach. Immunity induced by rubella vaccines must persist throughout the childbearing years, a period of about 30 years. We have reported persistence of rubella antibody at values exceeding 15 000 IU/l in 89 4% of volunte...

The new technique of molecular imprinting has increasingly been adopted by research laboratories worldwide during the last few years. We have studied the use of such imprints against drugs as artificial antibody-binding mimics in competitive radioimmuno-style binding assays. The recognition sites "molded" in the polymers mimic the binding sites of natural antibodies in their interactions with t...

In vivo microdialysis coupled with HPLC and radioimmuno-assay techniques were used to analyze dopamine (DA) and neurotensin (NT) in prefrontal cortical extracellular fluid following electrical stimulation of mesocortical axons. The release (overflow into the extracellular fluid) of both DA and NT increased with increasing number of impulses and with frequency. At the lowest frequency tested (2....

The pharmacokinetics and the prostaglandin (PG) synthesis inhibiting effect of flunixin were determined in 6 Norwegian dairy goats. The dose was 2.2 mg/kg body weight administered by intravenous (i.v.). intramuscular (i.m.) and oral (p.o.) routes using a cross-over design. Plasma flunixin content was analysed by use of liquid chromatography and the PG synthesis was evaluated by measuring plasma...

Abstract Since Zirconium-89 ( 89 Zr or Zr-89) decays by emitting positron with a half-life of 78.4 hours, it has been suggested as diagnostic radioisotope for cancer. Normally, is generated irradiating an enriched yttrium-89 Y Y-89) target protons via Y(p,n) nuclear reaction. Optimum proton energy employed to produce high Zr-89 yield and low radioactive impurities required be determined so that...
