Manganese is an essential microelement. Manganese deficiency affects reproduction performance and reproductive hormones in layers. However, little is known about its effects and the possible mechanism in regulating reproduction in broiler breeder hens. In the current study, broiler breeder hens at peak production were fed with diets supplemented with 0, 120, or 240 mg of Mn/kg as MnSO4 or Mn pr...

Because manganese (Mn) is potentially toxic, and because dietary fat type may affect Mn absorption, the objectives of the current study were to determine whether diets containing very low or very high amounts of Mn and enriched in either saturated or unsaturated fats affected measures of neuropsychological and basic metabolic function. Healthy young women were fed for 8 wk each, in a crossover ...

The effects of monovalent (Na, K) and divalent (Mg, Ca, Mn) ions on the interaction between DNA and histone are studied using the molecular combing technique. λ-DNA molecules and DNA-histone complexes incubated with metal cations (Na, K, Mg, Ca, Mn) are stretched on hydrophobic surfaces, and directly observed by fluorescence microscopy. The results indicate that when these cations are added int...

OBJECTIVES The aim of the study was to determine if isosorbide-5-mononitrate (IS-5-MN) 120 mg, taken once daily for 7 days, is associated with evidence of endothelial dysfunction and whether this effect is determined by increased free radical production. BACKGROUND Tolerance to nitroglycerin is associated with increased free radical production and abnormal endothelial function. To date, no da...

Sources of Zn, Mn, and Cu (IZMC) as sulfates or as amino acid complexes (OZMC) were used to supplement Cobb 500 breeder hen diets. Experimental treatments consisted of diets supplemented with 1) 100, 100, and 10 mg/kg of Zn, Mn, and Cu, respectively, from IZMC (control); 2) 60, 60, and 3 mg/kg of Zn, Mn, and Cu, respectively, from IZMC plus 40, 40, and 7 mg/kg of Zn, Mn, and Cu, respectively, f...

A nanocomposite comprising cerium oxide nanoparticles (CeO2 NPs) and polypyrrole (PPy) was fabricated onto a microelectrode for cholesterol sensing application. The oxidase (ChOx) immobilized on the CeO2 NPs/PPy/electrode by physical adsorption route. structure morphology of NPs/PPy were characterized X-ray diffraction, field emission scanning electron microscopy, energy dispersive spectroscopy...

Manganese (Mn), an essential trace element for plants in which it is involved redox reactions as a cofactor many enzymes, represents important factor environmental contamination. Excess Mn can lead to toxicity conditions natural and agricultural sites. one of the most severe growth limiting factors acid soil, accounts 21% total arable lands China. The more significant part Mn-toxicity its inter...
