The present paper introduces new classes of Stancu–Kantorovich operators constructed in the King sense. For these operators, we establish some convergence results, error estimations theorems and graphical properties approximation for considered, namely, that preserve test functions e0(x)=1 e1(x)=x, e2(x)=x2, as well e1(x)=x e2(x)=x2. class e2(x)=x2 is a genuine generalization introduced by Indr...

background: it is reasonable to think that some biochemical characteristics of follicular fluid (ff) surrounding the oocyte may play a critical role in determining the quality of oocyte and the subsequent potential needed to achieve fertilization and embryo development. objective: this study was carried out to evaluate the levels of ff homocysteine (hcy) in ivf candidate polycystic ovary syndro...

background: the uterus is a dynamic tissue responding to hormonal changes during reproductive cycles. as such, uterine stem cells have been studied in recent years. transcription factors oct4 and sox2 are critical for effective maintenance of pluripotent cell identity. objective: the present research evaluated the mrna expression of oct4 and sox2 in the uterine tissues of ovariectomized mice tr...

Two novel dicationic binuclear Cu(I) complexes of the type [{(BPPP)E2)}Cu]2[BF4]2 (E = S (3a); Se (3b)) bearing (BPPP)E2 (BPPP bis(diphenyl phosphino)pyridine) pincer systems were isolated, and structurally characterized. The...

We characterized the NADPH-dependent metabolism of 17beta-estradiol (E2) by liver microsomes from 21 male and 12 female human subjects. A large number of radioactive estrogen metabolite peaks were detected following incubations of [3H]E2 with male or female human liver microsomes in the presence of NADPH. The structures of 18 hydroxylated or keto estrogen metabolites formed by these microsomes ...

Background: Electric-quadrupole ($E2$) strengths relate to the underlying quadrupole deformation of a nucleus and present challenge for many nuclear theories. Mirror nuclei in vicinity line $N=Z$ represent convenient laboratory testing deficiencies such models, making use isospin-symmetry systems. Purpose: Uncertainties associated with literature $E2$ \textsuperscript{23}Mg are some largest $T_...
