1Role of Moringa oleifera in regulation of diabetes-induced oxidative stress显示文摘Objective:To evaluate the antioxidant activity of aqueous extract of Atoringa oleifeta M.oleifera) young leaves by in vivo as well as in vitro assays.Methods:In vitro study included estimation of total phenolic,total ilavonol,total flavonoid and total antioxidant power(FRAP assay).Tn addition, in vivo study was done with the identified most effective dose of 200 nig/kg of its lyophilized powder on normal and diabetic rats.Its effect on different oxidative free radical scavenging enzymes,viz,superoxide dismutase(SOD),catalase(CAT),glutathione-S-transferase(GST),lipid peroxide(LPO) contents were measured.Results:Significant increase in activities of SOD.CAT, GST while,a decrease in LPO content was observed.Whereas,total phenolic,flavonoid and ilavonol contents in the extract were found to be 120 mg/g of CAK,40.5 mg/g of QEK and 12.12 mg/g of QE,respectively.On the other hand.FRAP assay results of M.oleifera leaves was(85.00±5.00)μM of Fe^+/g of extract powder.Conclusions:The significant antioxidant activities of M.oleifera leaves from both in vivo as well as in vitro studies suggests that the regular intake of its leaves through diet can protect normal as well as diabetic patients against oxidative damage.Dolly Jaiswal Prashant Kumar Rai Shikha Mehta Sanjukta Chatterji Surekha Shukla Devendra Kumar Rai Gaurav Sharma Bechan Sharma Shahidul khair Geeta Watal 2013Asian Pacific Journal of Tropical Medicine2013,6,6:11

7Theoretical investigation on mechanical,thermal,and ultrasonic properties of epitaxial nanostructured ZrN layers growth on MgO(001)substrate显示文摘In the present study,we calculated the elastic,mechanical,and thermo-physical properties of Zirconium Nitride(ZrN)/Magnesium Oxide(MgO)(001)nanostructures in the temperature range of 50∼300 K using higher-order elastic constants.With two fundamental factors,nearest-neighbor distance and hardness parameter,in this tem-perature range,the second-and third-order elastic constants(SOECs and TOECs)are estimated using the Coulomb&Born-Mayer potential.The computed values of SOECs have been used to calculate Young’s modulus,thermal conductivity,Zener anisotropy,bulk modulus,thermal energy density,shear modulus,and Poisson’s ratio to as-sess the thermal and mechanical properties of the ZrN/MgO(001)nanostructured layer.Additionally,SOECs are used to calculate the wave velocities for shear as well as longitudinal modes of propagation along crystalline orientations<100>,<110>,and<111>in these temperature ranges.The temperature-dependent Debye average velocity,hardness,melting temperature,and ultrasonic Grüneisen parameters(UGPs)were evaluated.The frac-ture/toughness(B/G)ratio in the current investigation was greater than 1.75,indicating that the ZrN/MgO(001)nanostructured layer was ductile in this temperature range.The selected materials fully satisfied the Born me-chanical stability requirement.At this ambient temperature,it has been computed how long thermal relaxation takes to complete and how ultrasonic waves are attenuated by thermo-elastic relaxation and phonon-phonon interaction mechanisms.These results,in combination with other well-known physical properties,can be applied to the non-destructive testing of materials for various industrial applications such as microelectronic devices,optical coatings,batteries,and solar cells.Aadesh Kumar Prajapati Sachin Rai Prashant Srivastav Pramod Kumar Yadawa 2023ChemPhysMater2023,2,3:0
