Free radicals and antioxidants: Myths, facts and mysteries

Reactive oxygen species (ROS) and reactive nitrogen species (RNS) are well recognized for playing a dual role as both deleterious and beneficial species. Overproduction of ROS arising either from mitochondrial electron transport chain or excessive stimulation of NAD(P)H oxidase results in oxidative stress, a deleterious process that can be an important mediator of damage to cell structures, including lipids and...

Some wet routes for synthesis of hematite nanostructures

Increased attention has been paid to the synthesis of hematite nanoparticles recently due to its properties and application in various fields of modern technology. Various methods (aqueous and non-aqueous) have been applied in order to produce hematite nanostructures of required size and morphology suitable for these various applications. The aqueous route has been found to be simpler and more versatile than the...

Preconcentration and determination of Mercury(II) from natural water and milk sample by Histidine functionalized multi-walled carbon nanotubes (MWCNTs-His)

A simple method has been developed for the preconcentration of Mercury(II) [Hg(II)] based on the adsorption of its histidine functionalized multi-walled carbon nanotubes (MWCNTs-His) complex. The stability of a chemically MWCNTs-His were determined especially in concentrated hydrochloric acid which was then used as a recycling and pre-concentration reagent for further uses of MWCNTs-His. The application of this...

An assessment of surface water pollution status around Gboko abattoir

An assessment of surface water around Gboko abattoir was conducted to ascertain the pollution status of water around the area. The results showed mean values as: total dissolved solids (TDS), 1026.78 mg/L; TSS, 565.22 mg/L; dissolved oxygen (DO), 5.0 mg/L; phosphate, 8.89 mg/L and biochemical oxygen demand (BOD), 484.64 mg/L. These values were above regulatory standards. The values of; pH (6.6), sulphate (86.91 mg/L),...
