O-24: Increased Homocysteinein PCOS Affects Oocyte and Embryo Quality

Background: The biochemical characteristics of the follicular fluid (FF) play essential role in oocyte quality, the subsequent fertilization potential and embryo development. The oocyte quality and metabolism largely depends on follicular microenvironment. Present study aimed to investigate the relationship between oocyte quality and FF homocysteine (Hcy) level in women undergoing to IVF treatm...

[μ-10,21-Dimethyl-3,6,14,17-tetra­aza­tricyclo­[17.3.1.18,12]tetra­cosa-1(23),8(24),9,11,19,21-hexa­ene-23,24-diolato-κ8 N 3,N 6,O 23,O 24:N 14,N 17,O 23,O 24]bis­[(nitrato-κ2 O,O′)nickel(II)]

In the title centrosymmetric dinuclear nickel complex, [Ni(2)(C(22)H(30)N(4)O(2))(NO(3))(2)], each of the two Ni(II) atoms has a distorted octa-hedral geometry, defined by two N atoms and two O atoms from the macrocyclic ligand and two O atoms from a chelating nitrate anion. The two Ni atoms are bridged by two phenolate O atoms, forming a four-membered Ni(2)O(2) ring.

[μ-10,21-Dimethyl-3,6,14,17-tetra­za­tricyclo­[17.3.1.18,12]tetra­cosa-1(23),2,6,8,10,12 (24),13,17,19,21-deca­ene-23,24-diolato-κ4 N 3,N 6,O 23,O 24:κ4 N 14,N 17,O 23,O 24]bis­(perchlorato-κO)dimanganese(II)

In the centrosymmetric and dinuclear title complex, [Mn(2)(C(22)H(22)N(4)O(2))(ClO(4))(2)], the two Mn atoms are bridged by two phenolate O atoms of the N(4)O(2) macrocycle with an Mn⋯Mn distance of 2.9228 (11) Å. The distorted square-pyramidal N(2)O(3) coordination geometry is completed by an O atom derived from a perchlorate anion.

O-24: Prevalence of Primary Infertility in theIslamic Republic of Iran in 2004-2005

s:1696:"Background: This study aimed to determine the prevalence of lifetime and current primary infertility in Iran. The study was conducted in 2004-5 in all the 28 provinces of Iran. Materials and Methods: The study was conducted in 2004-5 in all the 28 provinces of Iran. We used a cluster sampling method to select 10,783 women aged 19-49 for the survey. Life-time primary infertility was defi...
