Fetal heart rate monitoring category 3 during the 2nd stage of labor is an independent predictor of fetal acidosis.

Objective: To determine whether fetal heart rate (FHR) monitoring categories during the 1st and 2nd stage of labor can predict arterial cord pH <7.2.

Materials And Methods: A case control study was conducted including 653 consecutive term deliveries (37 weeks gestation and above) that were divided according to fetal pH ≤ 7.

Differences in membrane fluidity and fatty acid composition between phenotypic variants of Streptococcus pneumoniae.

Phase variation in the colonial opacity of Streptococcus pneumoniae has been implicated as a factor in the pathogenesis of pneumococcal disease. This study examined the relationship between membrane characteristics and colony morphology in a few selected opaque-transparent couples of S. pneumoniae strains carrying different capsular types.
