Electronic structure calculations forZnFe2O4
Local density approximation was applied to scrutinize the electronic structure and magnetic properties of the spinel ferrite ${\mathrm{ZnFe}}_{2}{\mathrm{O}}_{4}$. Various cation distributions were established to obtain the ground state for the system. In magnetic crystals, the position of the atoms is not enough for symmetry determination. A structure prediction by decreasing the octahedral point group symmetry ${\mathrm{O}}_{h}$ of Fe to ${\mathrm{D}}_{4h}$, ${\mathrm{C}}_{4v}$, and ${\mathrm{C}}_{3v}$ was carried out. The effect of the exchange and correlation terms on the band structure of ${\mathrm{ZnFe}}_{2}{\mathrm{O}}_{4}$ was studied by the generalized gradient approximation $+$ th…
Mucin1 expression and gustatory function in postmenopausal females : a case-control observational study
Investigating possible relationship between Mucin1 expression levels in saliva, gustatory function, and taste perception in postmenopausal females.Using whole mouth taste test, twenty-five post-menopausal females (51.35 ± 5.22 years) and twenty-five premenopausal females (39.65 ± 6.46 years) were prospectively evaluated for gustatory function. The expression of mucin1 was investigated; RNA was isolated from stimulated whole saliva samples and real-time PCR was used to determine mucin1 mRNA levels relative to bactin and GAPDH mRNA levels.Significant difference was observed between postmenopausal and premenopausal women regarding intensity judgments of all tastants. The difference was more ev…
