Were analyzed 648 serum samples from laboratory staff in Goiânia, Goiás aiming detection of three serological markers of HBV: HBsAg, anti-HBsAg and anti-HBcAg. The HBsAg and anti-HBcAg positive samples were also analyzed for HBeAg, anti-HBeAg and anti-HBcAgIgM markers. HBV infection rate of 24.1% was observed and, from them, 0.7% were positive for HBsAg. Viral DNA was detected by PCR in two HBs...

The welfare of non-human primates used in scientific research must be safeguarded to promote scientific validity and for ethical reasons. Welfare can be improved by the refinement of practice, particularly if these refinements are applied to every aspect of the life of an animal used in the laboratory, from birth to death with the aim of both minimising harm and maximising well-being. Many refi...

A computer system for reporting and recording all specimens processed by the routine bacteriology laboratory at the Royal Postgraduate Medical School is described. Features of interest are the method of input using a mixture of 3-character alphanumeric codes and numbers, cumulative reporting to the wards, and selective listing of relevant previous results for the patient, which is available to ...

The present guidelines aim to provide comprehensive information regarding the laboratory diagnosis of infections caused by Chlamydia trachomatis in East European countries. These recommendations contain important information for laboratory staff working with sexually transmitted infections (STIs) and/or STI-related issues. Individual East European countries may be required to make minor nationa...

Between August 1970 and January 1971 nearly 150 of the staff of a London teaching hospital were affected by an illness with features in common with what is currently known as epidemic neuromyasthenia. Symptomatology was protean, clinical findings minimal, relapses frequent, and results of laboratory investigations, including virological studies, were generally negative. Most of the patients wer...

The Hydromechanics Laboratory supports midshipmen education, as well as midshipmen, faculty and staff research, in the areas of naval architecture and ocean engineering. The laboratory facilities include a large towing tank (380-ft long, 26ft wide, and 16-ft deep), a small towing tank (120-ft long, 8-ft wide, and 5-ft deep), a coastal engineering wave basin (52-ft long, 48-ft wide, and 2-ft dee...

Pregnancy. Puerperium. Breast stimulation. Stress physical (including excessive exercise) or psychological including venepuncture. Macroprolactinaemia: This refers to prolactin of high molecular mass, mostly complexes of monomeric prolactin with immunoglobulins (prolactin autoantibody complexes). These larger molecules have low bioactivity and a prolonged clearance rate similar to that of immun...

To evaluate the present situation and plan future directions with regard to implementation of universal precautions in laboratories testing blood samples, we carried out a national cross sectional study in 2003 on a representative sample of laboratories in Lebanon. We compared the results with those of a 1993 study. We found that the education profile of staff had improved, being now more speci...
