RESUMEN
Background: To compare efficacy of 75% silver nitrate chemical cautery as opposed to topical vasoconstrictor spray (xylometazoline 0.1%) in adult anterior epistaxis.Methods: This randomized controlled trial study was carried out at SMHS Hospital Srinagar from Jan 2019 to Dec 2019. 110 subjects that presented to ENT & HNS emergency with epistaxis and fulfilled the inclusion criteria were selected. Subjects were randomly distributed into two groups. Group-A individuals were treated by cauterization with 75% silver nitrate and Group-B individuals were treated with topical vasoconstrictor spray (xylometazoline 0.1%). All the subjects were reviewed at 1 month and success was determined in terms of control of epistaxis from same side of nose.Results: The mean age of the cohort was 48.5yrs (age range, 17-59). There were total 60 (54.4%) males and 50 (45.4%) females among the cases. Both the groups were comparable as regards the age, sex, duration and frequency of epistaxis. 91.2% cases in Group-A (silver nitrate cautery) and 73.5% cases in Group-B (xylometazoline spray 0.1%) had no further epistaxis at one-month follow-up (p=0.014).Conclusions: Chemical cauterization with silver nitrate is a feasible and safe technique for the treatment of adult anterior epistaxis and is more effective than topical vasoconstrictor spray.
RESUMEN
ABSTRACT The MYB family represents one of the most abundant classes of transcriptional regulators that perform pivotal role under different developmental processes and abiotic stresses. In present study, a MYB gene from Oryza sativa was selected for functional characterization. Bioinformatics analysis revealed that OsMYB1 cDNA encodes R2-R3 type DNA binding domain consisting of 413 amino acids having size of 44 kDa and pI of 6.24. DNA binding domain containing region was cloned and over-expressed in E. coli. Then, the survival of pGEX-OsMYB1 transformed E. coli cells was compared with control plasmid under different concentrations of NaCl, mannitol, high and low temperature. pGEX-OsMYB1 enhanced the survival of cells at high temperature and salinity. Electrophoretic mobility shift assays (EMSAs) have shown that recombinant OsMYB1 protein was able to bind with DIG labeled probe containing MYB binding site. RT-qPCR analysis revealed high MYB1 expression under wounding, salt, drought and heat stresses in rice. Expression was 23 fold higher in response to wounding demonstrating the worth of OsMYB1 up-regulation in wounding. Intrinsic disorder profile predicted that OsMYB1 exhibits 60% degree of intrinsic disorder proposing that these regions might be involved in DNA binding specificity and protein-protein interaction. The positive response of OsMYB1 suggests that its over-expression in crop plants may help in providing protection to plants to grow under abiotic stresses.
