Determination of in Vivo Biological Activities of Dodonaea Viscosa Flowers Against CCL4 Toxicity in Albino Mice With Bioactive Compound Detection

Abstract: Dodonaea viscosa L.Jacq. is an evergreen shrub and native to Asia, Africa, and Australia. It has been used as traditional medicine in different countries. The foremost objective of the current study was to discover the protective potential of D. viscosa flowers Methanol (DVM) and Chloroform (DVC) extracts against CCL4 induced toxicity in mice. This study was intended to identify phytochemicals through HPLC, GCMS, and FT-IR, as well as in vitro antioxidant and in vitro anti-tuberculosis activity. Our comprehensive findings indicate that Dodonaea viscosa is valuable and widespread herbal medicine through therapeutic potentials for curing various ailments. Dodonaeaviscosa flowersare found to have a protective effect against oxidative stress produced by CCL4 in the liver, kidney, and spleen. The intake of DV extracts restored the level of hepatic enzymes (ALP, AST ALT, and Direct bilirubin), hematological parameters (RBCs, WBCs, and Platelets), total protein, and liver antioxidant enzymes (SOD, GPx, and CAT) after a decline in levels by CCL4. Histopathological results discovered the defensive effect of 300 mg/kg of DVM extract against CCL4 induced damage, thus having an improved protective effect compared to DVC and control. As a result of metabolite screening, the total flavonoids and total phenolics were present in abundance. A phytochemical investigation by HPLC identified gallic acid, epicatechin, cumeric acid, flavonoids, while GCMS estimated oleic acid (Octadecenoic acid) (C18H34O2), Stearic acid (C18H36O2), Ricinoleic acid (C18H34O3), and Cedrol (C15H26O). DVM extract exhibited resistance against in vitro Mycobacterium tuberculosis strains. So this study proposed that the protective effect of DV against oxidative damage induced in the liver, kidney, and spleen can be correlated to the antioxidant compounds.

Peristaltic Blood Transport in Non-Newtonian Fluid Confined by Porous Soaked Tube: A Numerical Study Through Galerkin Finite Element Technique

Abstract: This novel investigation suggests the implementation of famous numerical technique namely Galerkin finite element technique for peristaltic study of non-Newtonian fluid confined by a porous tube. The rheological consequences for non-Newtonian materials are executed by using micropolar fluid. The problem is modeled in form of Navier–Stokes expressions. The flow simulations are carried by utilizing the impact of the magnetic field and uniform porous medium. Additionally, the role of inertial forces is also observed as a novelty for current analysis. Unlike typical investigations, the presumptions of lubrication theory are not implemented in the modeling which allows the participation of inertial forces in the governing equations and provided the results independent of wavelength. The solution of the modeled set of coupled non-linear partial differential equations is obtained by Galerkin finite element method with quadratic triangular elements. The verification of attained numerical results with available literature for low Reynolds number approximation is also presented and found in excellent agreement. It is observed that the peristaltic mixing enhances with increasing the inertial and Lorentz force while reverse observations are noticed with for the dense porous medium. An increase in pressure rise per wavelength is observed for micropolar fluid as compared to that of viscous fluid. It is further claimed that the peristaltic mixing is improved with increasing the Reynolds number and permeability of porous medium.

Darcy resistance flow of Sutterby nanofluid with microorganisms with applications of nano-biofuel cells

Abstract: The objective of current research is to endorse the thermal aspect of Sutterby nanofluid containing the microorganisms due the stretched cylinder. The features of nonlinear thermal radiation, Darcy resistance and activation energy are also incorporated to inspect the thermal prospective. The problem is further extended with implementation of modified Fourier and Fick's theories. The results are presented for the stretched cylinder and also for stationary plate. The numerical formulation for the problem is presented by following the shooting technique. The comparative numerical is performed to verify the computed simulations. The results convey that the presence of Darcy resistance parameter enhanced the velocity more effectively for stretched cylinder. A reduction in velocity due to Sutterby fluid parameter and buoyancy ratio parameter has been observed. Moreover, the temperature profile enhanced with larger sponginess parameter more effectively for stretching cylinder.
