A new parasitoid wasp, sp. n. (Braconidae, Alysiinae), from a city park in the centre of Amsterdam.

Background: The parasitic wasp genus Foerster, 1863, belongs to the large subfamily Alysiinae Leach, 1815 (Hymenoptera: Braconidae) and contains solitary or gregarious endoparasitoids of larvae of cyclorrhaphous Diptera living in decaying organic matter.

New Information: A new species, sp. n.

A bilateral ankle manipulator to investigate human balance control.

The ankles play an important role in human balance. In most studies investigating balance control the contribution of the left and right leg is not separated. However, in certain pathologies such as stroke and Parkinson's disease, balance control can be asymmetric.

A collaborative trial of a semi-automatic system for slide preparation and screening in cervical cytopathology.

We report a test of an experimental system for machine-aided screening in cervical cytology, comprising the 'CYTOPRESS' semi-automatic slide preparation system (Nijmegen) and the 'CERVIFIP' interactive scanner (Edinburgh). Material from women attending clinics in Edinburgh and Nijmegen was stratified according to the severity of the conventional laboratory diagnosis and selected randomly within strata for inclusion in the test. Monolayered slides were prepared by CYTOPRESS from cervical scrape material remaining after preparation of conventional smears and scanned by CERVIFIP to determine the positions of the most 'suspicious' objects.

IgM-antibodies against T. pallidum detected in sera from mothers of stillborn babies in Mozambique by the solid-phase haemadsorption assay (SPHA).

Serum samples taken at the delivery from 27 syphilitic mothers in Mozambique, 16 with stillborn babies and 11 with healthy babies were tested upon presence of IgM antibodies against T. pallidum by the solid-phase haemadsorption assay (SPHA). Fourteen out of the 16 serum samples from mothers with stillborn babies but only one out of the 11 samples from mothers with healthy babies were found positive by the SPHA test.

Haematological study in Cabo Delgado province, Mozambique; sickle cell trait and G6PD deficiency.

A haematological study was done in several villages in the northern province of Cabo Delgado in Mozambique. The prevalence of sickle cell trait (HbAS) was found to be about 4%. The prevalence of G6PD deficiency in males was about 18%.
