Posterior Uterine Rupture Causing Fetal Expulsion into the Abdominal Cavity: A Rare Case of Neonatal Survival

Introduction. Uterine rupture is a potentially catastrophic complication of vaginal birth after caesarean section. We describe the sixth case of posterior uterine rupture, with intact lower segment scar, and the first neonatal survival after expulsion into the abdominal cavity with posterior rupture. Case Presentation. A multiparous woman underwent prostaglandin induction of labour for postmaturity, after one previous caesarean section. Emergency caesarean section for bradycardia revealed a complete posterior uterine rupture, with fetal and placental expulsion. Upon delivery, the baby required inflation breaths only. The patient required a subtotal hysterectomy but returned home on day 5 postnatally with her healthy baby. Discussion. Vaginal birth after caesarean section constitutes a trial of labour, and the obstetrician must be reactive to labour events. Posterior uterine rupture is extremely rare and may occur without conventional signs. Good maternal and fetal outcome is possible with a prompt, coordinated team response

Not AvailableRNA editing is a post transcriptional modification which occurs at specific sites of RNA molecules in the chloroplasts of higher plants. Although, systematic studies have been carried out in several plants, very scant information is available with regard to the oilseed crop, sunflower. Here, we systematically investigated and compared chloroplast RNA editing status of four Helianthus species viz., H. annuus (including its three genotypes 2023B, TX16R, ID25), H. debilis, H. praecox and H. niveus and their respective fungal (powdery mildew) infected plants using bioinformatics approach from RNA-Seq data. We discovered 244 RNA editing sites (RES), including 106 (43.62%) in protein coding regions with an average number of 67 edit sites and 32 common RES distributed among six controls and their respective pathogen infected plants. A comparison of these Helianthus species transcriptomes to the genomes of A. thaliana, O. sativa and Z. mays led to discovery of 54 novel RES in 21 genes which were C to U conversions in all species. These studies provide a comprehensive picture of plastid RNA editing events in Helianthus species. We identified complete RNA editing events in four species of Helianthus and pathogen specific differential RNA editing for the first time, which would be a basis for future understanding of disease specific phenomena.Not Availabl

Not AvailableIdentification of genes expressed during the Golovinomyces orontii infection process in Helianthus niveus assumes importance for incorporation of resistance to powdery mildew in cultivated sunflower (H. annuus L.) from this donor species. RNA-seq analysis of control (uninfected) and infected samples of H. niveus resulted in identification of 231,754 transcripts. A total of 3726 transcripts were differentially expressed of which 205 were specifically expressed in control and 1961 in infected samples. Functional annotation of the differentially expressed transcripts showed significant upregulation of GRAS type transcription factor (TF) and plant specific GATA-type zinc finger TF in infected samples and the K-box, MADS box TF and WRKY family TF in control tissues. Gene ontology classification showed that genes involved in cell and cell part functioning, catalytic and metabolic processes were significantly and highly expressed. This is the first application of RNA-Seq for identification of key genes and pathways involved in powdery mildew infection process in a Helianthus species conferring resistance to the pathogen.Not Availabl

Electrochemical analysis on poly(ethyl methacrylate)-based electrolyte membranes

Polymer blend composed of poly(vinyl chloride) and poly(ethyl methacrylate) with lithium perchlorate (LiClO4) and the plasticizer ethylene carbonate (EC) mixture with propylene carbonate, γ-butyrolactone (GBL), dibutyl phthalate and diethyl carbonate have been synthesized using the solution casting technique. Structural changes and thermal stability of the films were resolved using X-ray diffraction analysis and thermogravimetric/differential thermal analysis, respectively. The membrane that contains EC+ GBL exhibits maximum ionic conductivity of the order of 1.208 × 10-3 S cm-1 at 303 K. The temperature-dependent ionic conductivity of the polymer membranes has been estimated using AC impedance analysis.Published versio
