BACKGROUND Oxidative stress is thought to be involved in the pathogenesis of microalbuminuria in Sickle cell anemia (SCA). Antioxidant enzymes such as glutathione peroxidase (GPx) and Cu-Zn superoxide dismutase (SOD) may play an important protective role. This study aimed to evaluate the association between albuminuria and these two antioxidant enzymes. METHODS We consecutively recruited Stea...

Research of metal complexes with biologically active ligand is one of high scientific and practical interest. Formation of binary and ternary complexes of metal ions such as Cu(II), Co(II), Pb(II), Zn(II) and Cd(II) with biologically important ligand were investigated. Where nucleic acid Adenine (A) used as primary ligand and amino acid Histidine (B) used as secondary ligand. Potentiometric tec...

An Al-Zn-Mg-Cu alloy without Sc or Zr additions was subjected to overaging and processing by equal channel angular pressing, obtaining a grain size of ∼160 nm and a fraction of high-angle boundaries of 56%. The high elongations attained at high strain rate (10-10 s) and low test temperature (250-300 oC) are attributed to the formation of new recrystallized grains, ∼500 nm in size, during heatin...

Based on the theory of relativistic mean-field effective interactions, we explore effect superstrong magnetic fields (SMFs) nuclear single-particle level structure, blinding energy, and electron Fermi energy in strongly magnetized super-Chandrasekhar white dwarfs (SMSWDs). We also discuss capture (EC) instability from threshold mass density (TMD) pressure (TP) for some typical iron group nuclei...

In the seniority scheme the reduced B(E2: 0 + 1 → 2 + 1) (B(E2)↑) transition probability of even-even nuclei can be related to the product of the number of particles by the number of holes of the valence space. This very simple expression is used to analyze at the same time the experimental B(E2)↑ values of 56−68 Ni and those of 62−72 Zn. The evolution of these B(E2)↑ values with neutron number...

Background: Anti-inflammatory intermediaries like contactin-1 (CNTN-1) play an essential role in regulating several diseases, such as Rheumatoid Arthritis (RA). This paper explores the relationship between CNTN-1 and a number of trace elements RA patients with without COVID19. Accordingly, it investigates whether there are any correlations some elements. Materials Methods: The involved 56 patie...
