Primary cesearean section in multigravidas

Background: Cesarean section is one of the widely performed surgical procedures across the world. Cesarean section is associated with increased risk of maternal morbidity and mortality, despite remarkable improvements in the safety. The objective of the present study is to study the cesearean section in the context of various indications, parity, intraoperative complications, post-operative morbidity, and perinatal morbidity among multigravidae undergoing cesarean section for first time.Methods: The present study was carried out at Yenepoya medical college hospital. All multigravidas who had delivered vaginally once or more and who underwent primary caesarean sections for the first time during time period of August 2015-May 2016 were included in study and various factors are analyzed.Results: In our study most of primary cesearean sections were in second paras who constituted 50%, followed by 4/> paras constituting 29.54%, and it was observed that incidence in third paras was 20.45%. 75% of the patients underwent emergency cesearean section and 25% had elective ceserean section. The most common indication for cesearean in our study was observed to be fetal distress accounting for 25% of the cases, 2nd most common being malpresentations (19.31%), non-progress of labor constituting 11.36% of cases. Intra operative complications were noted in 6.81% of cases, most common complication being extension of uterine incision extension of uterine incision.Conclusions: Complications may occur in women who previously had a normal vaginal delivery requiring interventions in the form of caesarean section and is not uncommon. Though to a small extent, they are contributing to rise is total caesarean section rates seen. There are many cases where a caesarean becomes mandatory for her. The fact that a multipara who has had one or more vaginal deliveries should be regarded as an optimistic historical fact, not as diagnostic-criteria for spontaneous delivery of the pregnancy at hand. A parous woman needs good obstetric care to improve maternal and neonatal outcome and still keeping caesarean section to a lower rate

Comprehensive Analysis of Serum Small Extracellular Vesicles-Derived Coding and Non-Coding RNAs from Retinoblastoma Patients for Identifying Regulatory Interactions

The present study employed nanoparticle tracking analysis, transmission electron microscopy, immunoblotting, RNA sequencing, and quantitative real-time PCR validation to characterize serum-derived small extracellular vesicles (sEVs) from RB patients and age-matched controls. Bioinformatics methods were used to analyze functions, and regulatory interactions between coding and non-coding (nc) sEVs RNAs. The results revealed that the isolated sEVs are round-shaped with a size 11 ± 8.1 particles/mL, and zeta potential of 11.1 to −15.8 mV, and expressed exosome markers CD9, CD81, and TSG101. A total of 6514 differentially expressed (DE) mRNAs, 123 DE miRNAs, and 3634 DE lncRNAs were detected. Both miRNA-mRNA and lncRNA-miRNA-mRNA network analysis revealed that the cell cycle-specific genes including CDKNI1A, CCND1, c-MYC, and HIF1A are regulated by hub ncRNAs MALAT1, AFAP1-AS1, miR145, 101, and 16-5p. Protein-protein interaction network analysis showed that eye-related DE mRNAs are involved in rod cell differentiation, cone cell development, and retinol metabolism. In conclusion, our study provides a comprehensive overview of the RB sEV RNAs and regulatory interactions between them

Generation of high-titer viral preparations by concentration using successive rounds of ultracentrifugation

<p>Abstract</p> <p>Background</p> <p>Viral vectors provide a method of stably introducing exogenous DNA into cells that are not easily transfectable allowing for the ectopic expression or silencing of genes for therapeutic or experimental purposes. However, some cell types, in particular bone marrow cells, dendritic cells and neurons are difficult to transduce with viral vectors. Successful transduction of such cells requires preparation of highly concentrated viral stocks, which permit a high virus concentration and multiplicity of infection (MOI) during transduction. Pseudotyping with the vesicular stomatitis virus G (VSV-G) envelope protein is common practice for both lentiviral and retroviral vectors. The VSV-G glycoprotein adds physical stability to retroviral particles, allowing concentration of virus by high-speed ultracentrifugation. Here we describe a method report for concentration of virus from large volumes of culture supernatant by means of successive rounds of ultracentrifugation into the same ultracentrifuge tube.</p> <p>Method</p> <p>Stable retrovirus producer cell lines were generated and large volumes of virus-containing supernatant were produced. We then tested the transduction ability of virus following varying rounds of concentration by ultra-centrifugation. In a second series of experiments lentivirus-containing supernatant was produced by transient transfection of 297T/17 cells and again we tested the transduction ability of virus following multiple rounds of ultra-centrifugation.</p> <p>Results</p> <p>We report being able to centrifuge VSV-G coated retrovirus for as many as four rounds of ultracentrifugation while observing an additive increase in viral titer. Even after four rounds of ultracentrifugation we did not reach a plateau in viral titer relative to viral supernatant concentrated to indicate that we had reached the maximum tolerated centrifugation time, implying that it may be possible to centrifuge VSV-G coated retrovirus even further should it be necessary to achieve yet higher titers for specific applications. We further report that VSV-G coated lentiviral particles may also be concentrated by successive rounds of ultracentrifugation (in this case four rounds) with minimal loss of transduction efficiency.</p> <p>Conclusion</p> <p>This method of concentrating virus has allowed us to generate virus of sufficient titers to transduce bone marrow cells with both retrovirus and lentivirus, including virus carrying shRNA constructs.</p
