RESUMEN
In this present study conducted with the LFGD (Low-Frequency Glow Discharge) (Ar + O2) plasma treated maize seeds, to inspect the effect on seed surface modifications, seed germination, growth, development, productivity and nutritional compositions of maize plants. This study reported that LFGD (Ar + O2) plasma treated maize seeds have a potential effect to change its smooth seed surfaces and, it becomes rougher. It also enhances the seed germination rate up to (15.88%), which might help to increase the shoot length (33.42%), root length (10.67%), stem diameter (13.37%), total chlorophyll content (46.93%), total soluble protein (52.48%), total soluble phenol (21.68%) and sugar (1.62%) concentrations in respect controls of our experimental plants. For this reason, the acceptable treatment duration for maize seeds were 30sec, 60sec, 90sec and 120sec. After treatment, the plants exhibited a significant increase in CAT, SOD, APX and GR activities in the leaves and roots, and also significantly changes in H2O2 (208.33 ± 5.87µ molg-1 FW) in the leaves and (61.13 ± 1.72µ molg-1 FW) in the roots, NO was (369.24 ± 213.19µ molg-1FW) and (1094.23 ± 135.44µ molg-1FW) in the leaves and roots. LFGD plasma treatment also contributed to enhancement of productivity (1.27%), nutritional (moisture, ash, fat, and crude fiber) compositions, and iron and zinc micro-nutrition concentrations of maize. From this research, LFGD (Ar + O2) plasma treatment showed a potential impact on the maize cultivation system, which is very effective tools and both in nationally and internationally alter the conventional cultivation system of maize. Because it promotes seed surface modification, improved germination rate, shoot length, root length, chlorophyll content, some of the growths related enzymatic activity, nutrient composition, iron, and zinc micro-nutrients and the productivity of maize.
RESUMEN
Naja kaouthia is one of the most prevalent medically important snakes of North East India and Bangladesh responsible for most of the bite cases. In this study, an attempt was made to decipher venom variation of Naja kaouthia venom from North East India and Bangladesh. Using multidimensional methods including reverse phase HPLC, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (1D-PAGE) and two-dimensional gel electrophoresis (2D-PAGE), the quantitative differences in venom composition have been revealed. Moreover, tested in-vitro biochemical and biological activities also exhibited differences which could be due to venom variability. Furthermore, neutralization efficacy of commercially available Indian polyvalent antivenoms (Vins, Bharat Serum, Haffkine) was evaluated and the results displayed significant differences in neutralizing efficacy between the antivenoms. Immunoblotting experiments showed antivenom molecules cross reacted with high molecular mass components while poorly reacted towards low molecular mass proteins. Immuno-depletion study demonstrated that Vins polyvalent antivenom was poor in immunocapturing the venom proteins of both North East Indian and Bangladesh origin Naja kaouthia at the ratio of 1:16 (venom: antivenom).
