Sources and Quality of Knowledge of Ante-Natal Care Physicians about Oral Conditions in Pregnancy: The Need to Do More

Context: During pregnancy, women are at a greater risk of experiencing poor oral health and this can affect pregnancy outcome. It is important that ante-natal care givers be knowledgeable on possible oral conditions that can affect the pregnant woman so that she can be adequately managed.Objective: To evaluate the sources and quality of knowledge of ante-natal care physicians about oral conditions in pregnancy.Study design, Setting and Subjects: A descriptive cross-sectional study of ante-natal care physicians at the University of Benin Teaching Hospital.Main outcome measures: Information on demographic characteristics, knowledge of oral conditions in pregnancy, effect of oral micro-organisms on mother and child, efficacy of routine scaling and polishing on reduction of oral micro-organisms and sources of respondents' dental information.Result: 81.3% and 30.8% of the respondents knew that gingivitis and periodontal disease respectively were sometimes seen in pregnancy. Majority of the respondents thought that oral micro-organisms had effects on mother and child. Only 42.1% thought that conventional scaling and polishing would reduce the oral microorganisms. There was statistically significant relationship between quality of knowledge and dental textbook as source of dental information.Conclusion: This study highlights the dearth of knowledge among  ante-natal care physicians about oral diseases which may have  consequences on maternal and fetal health, emphasizing the need to do more

The bacterial transposon Tn7 causes premature polyadenylation of mRNA in eukaryotic organisms: TAGKO mutagenesis in filamentous fungi

TAGKO is a Tn7-based transposition system for genome wide mutagenesis in filamentous fungi. The effects of transposon insertion on the expression of TAGKO alleles were examined in Magnaporthe grisea and Mycosphaerella graminicola. Northern analysis showed that stable, truncated transcripts were expressed in the TAGKO mutants. Mapping of the 3′-ends of TAGKO cDNAs revealed that they all contain Tn7 end sequences, regardless of the transposon orientation. Polyadenylation signals characteristic of eukaryotic genes, preceded by stop codons in all frames, are located in both ends of the bacterial transposon. Thus, TAGKO transcripts are prematurely polyadenylated, and truncated proteins are predicted to be translated in the fungal mutants. Depending on the extent of protein truncation, TAGKO mutations in HPD4 (encoding p-hydroxyphenylpyruvate dioxygenase) resulted in tyrosine sensitivity in the two fungi. Similarly, a particular M.grisea CBS1 (encoding cystathionine β-synthase) TAGKO cDNA failed to complement cysteine auxotrophy in a yeast CBS mutant. TAGKO, therefore, represents a useful tool for in vivo study of truncated gene products in filamentous fungi.postprin
