The effects of dimethyl sulfoxide and ethylene glycol as vitrification protectants on different cleavage stages of mouse embryo quality
The effect of modified vitrification was assessed on cellular development capability in mouse embryos cultured in vitro. In this study, 466 embryos (from zygote to morula stages) were vitrified then thawed embryos have been incubated for in vitro farther development up to blastocyst stage. Also, vitrification and thawing procedures were the same for all experimental groups. Mouse different embr...
متن کاملRing Cleavage of Some Bicylic Compounds Derived from 1,2,4-Triazine
Ring cleavage occurred when 1,2,4-triazino-1,2,4-triazines (3), (4) and (5) were treated with concentrated hydrochloric acid to yield N-substituted triazines (7) and (8). These confirm the given configuration assigned to the isomeric triazinotriazines. 6-Methyl-2-phenyl-7H-oxazolo [3,2-b][1,2,4]-triazin-7-one (9) underwent ring cleavage on treatment with sodium alkoxide to afford 3-alkoxy-1...

متن کاملPoly[μ3-chlorido-μ2-chloridodichlorido(μ-dimethyl sulfoxide-κ2 O:S)(dimethyl sulfoxide-κO)(μ-pyrimidine-κ2 N:N′)ruthenium(III)sodium]
The title complex, [NaRuCl(4)(C(4)H(4)N(2))(C(2)H(6)OS)(2)](n), is the sodium salt of monoanionic octa-hedral [Ru(III)Cl(4)(pyrimidine)(DMSO)](-) in which the sulfur-bound dimethyl sulfoxide (DMSO) and pyrimidine ligand are oriented trans to one another on the Ru(III) atom. The average of the four Ru-Cl bond lengths is 2.355 (15) Å, and the Ru-S and Ru-N bond lengths are 2.2853 (3) and 2.1165 (...
متن کاملVibrational spectroscopic force field studies of dimethyl sulfoxide and hexakis(dimethyl sulfoxide)scandium(III) iodide, and crystal and solution structure of the hexakis(dimethyl sulfoxide)scandium(III) ion.
Hexakis(dimethyl sulfoxide)scandium(III) iodide, [Sc(OS(CH(3))(2))(6)]I(3) contains centrosymmetric hexasolvated scandium(III) ions with an Sc-O bond distance of 2.069(3) angstroms. EXAFS spectra yield a mean Sc-O bond distance of 2.09(1) angstroms for solvated scandium(III) ions in dimethyl sulfoxide solution, consistent with six-coordination. Raman and infrared absorption spectra have been re...
