Evaluation of the relationship of cytokines concentrations tumor necrosis factor-alpha, interleukin-6, and C-reactive protein in obese diabetics and obese non-diabetics: A comparative study.

Obesity has been linked to a low-grade inflammatory process in the white adipose tissue. Our study aims to detect the relationship between cytokine levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and C-reactive protein (CRP) in obese diabetics, compared to obese non-diabetics, Iraqi individuals. Ninety Iraqi adults, 45 type 2 diabetic and 45 non-diabetic obese, were selected as controls.

An electrochemical biosensor based on cobalt nanoparticles synthesized in iron storage protein molecules to determine ascorbic acid.

The electrochemical detection of ascorbic acid (AA) was investigated using a cobalt(III)-ferritin immobilized on a self-assembled monolayer modified gold electrode in phosphate buffer solution (pH 7.5). The modified electrode showed excellent electrochemical activity for oxidation of AA.

Apoferritin-templated biosynthesis of manganese nanoparticles and investigation of direct electron transfer of MnNPs-HsAFr at modified glassy carbon electrode.

Manganese nanoparticles (MnNPs) were created within horse spleen apoferritin (HsAFr) cavity nanotemplates. Transmission electron microscopy revealed the particle size to be 6 nm. Intrinsic fluorescence data showed that the mineralization acted as a quencher of the HsAFr fluorescence, and extrinsic fluorescence data revealed that the hydrophobic binding site at the surface of HsAFr was not changed.
