Comparison of the 24 kDa flagellar calcium-binding protein cDNA of two strains of Trypanosoma cruzi.
DNA sequences encoding the 24 kDa flagellar calcium binding protein (FCaBP) of two strains of Trypanosoma cruzi were found to differ at fourteen positions, six of which result in amino acid differences. Four of the amino acid differences are located within the calcium-binding domains of FCaBP; however, none is predicted to affect the calcium-binding ability of the protein. Chromosomes harboring the FCaBP gene clusters differ in size among T. cruzi strains.
Molecular comparison of the mitochondrial and cytoplasmic hsp70 of Trypanosoma cruzi, Trypanosoma brucei and Leishmania major.
We compared the expression and localization of the mitochondrial and cytoplasmic hsp70 of the protozoans Trypanosoma cruzi, Trypanosoma brucei and Leishmania major. The mitochondrial protein is encoded by multiple mRNA in all species, while the cytoplasmic protein is encoded by a single mRNA. In all three species, the mitochondrial hsp70 is concentrated in the kinetoplast, a submitochondrial structure that houses the unusual DNA (kDNA) that characterizes this group of organisms, while the cytoplasmic protein is distributed throughout the cell. These results suggest that, in all kinetoplastid species, mt-hsp70 has a specific function in kDNA biology, possibly in the processes of kDNA replication, RNA editing or kinetoplast structure.
Intrapartum intervention and delivery outcome in low-risk pregnancy.
A retrospective cohort study of 1597 low-risk pregnancies assessed the effects of obstetrical intervention using logistic regression. Both maternal and neonatal morbidity were low (15.2 percent and 3.8 percent, respectively). Epidural analgesia, oxytocin, or both, were associated with worse maternal outcome, and neonatal outcome was worse when oxytocin was used. However, epidural analgesia seemed to provide a protective neonatal effect when oxytocin was used during labor. Both elective and medically necessary use of these interventions were associated with increased morbidity. If obstetrical interventions, particularly oxytocin and epidural analgesia, are applied in low-risk pregnancies, labors must be monitored carefully and the risk-benefit ratios judged advantageous.
