Synthesis, Characterization and Biological Activity of Mn(II)-Morin Complex

open access: yesPakistan Journal of Analytical & Environmental Chemistry, 2016
The article illustrates about the synthesis of Mn(II)-Morin complex in methanol solvent. The characterization of the complex was carried out using UV-visible, IR, 1H NMR spectroscopic techniques and thermal (i.e. TGA, DSC) techniques.

Free radical scavenging mechanism of 1,3,4-oxadiazole derivatives: thermodynamics of O–H and N–H bond cleavage

open access: yesHeliyon, 2020
The thermodynamics of free radical scavenge of 1,3,4-oxadiazole derivatives towards oxygen-centred free radicals were investigated by the density functional theory (DFT) method in the gas phase and aqueous solution.

Elevated liver enzymes is not an impediment to allopurinol dose escalation: an observational cohort study

open access: yesArthritis Care &Research, Accepted Article.
Objective Routine liver enzyme monitoring is advocated while on allopurinol but supporting guidance is lacking. We assessed the incidence and factors associated with elevated liver enzymes in gout patients commenced on allopurinol. Methods 150 patients with gout and normal baseline serum aminotransferases initiated on allopurinol were followed ...

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Examining the Use of Naturally Occurring Free Radical Scavengers Against UV Light Damage in Cancer Prevention [PDF]

open access: yes, 2022
A strong association has been found between mutated p53 tumor suppressor genes and cancers in humans. Cancers arise from a culmination of genetic and environmental factors, including exposure to ultraviolet (UV) light from the sun.

Correlation of serum IgE with stress in Indian dromedaries affected with skin wounds [PDF]

open access: yesJournal of Stress Physiology & Biochemistry, 2010
The present investigation was planned to explore stress induced changes in the levels of IgE by correlating them with the important parameters of stress like cortisol and free radical scavengers in the serum of Indian dromedaries.
