TL;DR: Nickel-doped cobalt ferrite nanoparticles based on Andrographis paniculata plant extract were prepared through the microwave-assisted method as mentioned in this paper, and the obtained nanoparticles were analyzed using XRD, FTIR, UV-DRS, SEM with EDAX, and HRTEM with SAED.
Abstract: Nickel-doped cobalt ferrite nanoparticles based on Andrographis paniculata plant extract were prepared through the microwave-assisted method. The obtained nanoparticles were analyzed using XRD, FTIR, UV-DRS, SEM with EDAX, and HRTEM with SAED. XRD exhibits a cubic lattice structure of ferrites and the lattice parameter decreases with an increase in nickel dopant. The vibrational stretching mode of the metal–oxygen bond is observed for tetrahedral and octahedral sites. The optical energy bandgap of pure CoFe2O4 nanoparticles gradually increases with nickel doping. The luminescence spectrum showed the violet, yellow, green, and orange emissions of synthesized nanoparticles. Further, photodegradation of prepared nanoparticles was assessed for the degradation of Methylene blue, Rhodamine B, Eriochrome black T, Rose bengal, and Evan’s blue dyes. Antibacterial activity of synthesized nanoparticles was tested against Gram-positive and Gram-negative bacterial strains. The antibacterial activity improved with Ni doping when compared with pure CoFe2O4 nanoparticles.

TL;DR: Among the two extracts studied, methanol leaf extract was found to possess significant wound healing activity followed by aqueous extract, which was evidenced by decrease in the period of epithelialization, increase in the rate of wound contraction, skin breaking strength, granulation tissue dry weight, hydroxyproline content and breaking strength ofgranulation tissue.
Abstract: The wound healing efficacy of aqueous and methanolic leaf extracts of Leucas hirta was evaluated in excision, incision and dead space wound models. The parameters studied include rate of wound contraction, period of complete epithelialization, tensile strength of incision wound and granulation tissue, granulation tissue dry weight, hydroxyproline content and histological studies of granulation tissue. Among the two extracts studied, methanol leaf extract was found to possess significant wound healing activity followed by aqueous extract, which was evidenced by decrease in the period of epithelialization, increase in the rate of wound contraction, skin breaking strength, granulation tissue dry weight, hydroxyproline content and breaking strength of granulation tissue. Histopathological study of the granulation tissue evidenced increased collagenation when compared to control group of animals.

TL;DR: The genotoxic potential of an anticancer drug, tamoxifen citrate, was studied in the in vivo mouse system using the sperm abnormality assay and Statistically significant sperm abnormalities revealed the genot toxic potency of this drug.
Abstract: The genotoxic potential of an anticancer drug, tamoxifen citrate, was studied in the in vivo mouse system using the sperm abnormality assay. Sperms of Swiss albino mice were examined after 5 weeks of repeated administration of different doses of the drug for 10 days. The doses used were 0.1, 0.2, 0.4 and 0.8 mg/kg b.w. per day. Statistically significant sperm abnormalities revealed the genotoxic potency of this drug.

TL;DR: In this article, the effect of nonlinear thermal radiation on double diffusive free convective boundary layer flow of a viscoelastic nanofluid over a stretching sheet was investigated.
Abstract: The present exploration deliberates the effect of nonlinear thermal radiation on double diffusive free convective boundary layer flow of a viscoelastic nanofluid over a stretching sheet. Fluid is assumed to be electrically conducting in the presence of applied magnetic field. In this model, the Brownian motion and thermophoresis are classified as the main mechanisms which are responsible for the enhancement of convection features of the nanofluid. Entire different concept of nonlinear thermal radiation is utilized in the heat transfer process. Appropriate similarity transformations reduce the nonlinear partial differential system to ordinary differential system which is then solved numerically by using the Runge–Kutta–Fehlberg method with the help of shooting technique. Validation of the current method is proved by having compared with the preexisting results with limiting solution. The effect of pertinent parameters on the velocity, temperature, solute concentration and nano particles concentration profiles are depicted graphically with some relevant discussion and tabulated result. It is found that the effect of nanoparticle volume fraction and nonlinear thermal radiation stabilizes the thermal boundary layer growth. Also it was found that as the Brownian motion parameter increases, the local Nusselt number decreases, while the local friction factor coefficient and local Sherwood number increase.
