The aim of this study was to investigate the effect of different concentrations of royal jelly (RJ) on in vitro maturation (IVM), fertilization, cleavage, blastocyst rates, glutathione (GSH) content in ovine oocyte, mRNA abundance of antioxidant enzymes in both oocyte and cumulus, and glucose metabolism-related genes in cumulus cells. In vitro maturation of oocyte was performed in the presence of control (RJ₀), 2.5 (RJ_2.5), 5 (RJ₅), and 10 (RJ₁₀) mg/mL of RJ. Nuclear status, intracellular GSH content in oocytes, and mRNA abundance of selected genes were evaluated following 24 h of IVM. Following the IVM, fertilization and embryo culture were carried out in all the groups and embryonic development was examined The addition of 10-mg/mL RJ to maturation media not only yielded a higher number of oocytes at MII stage but also showed an increased level of intracellular GSH content than did RJ_2.5 and control groups. Fertilization, cleavage, and blastocyst rate were higher in the RJ₁₀ treatment group in comparison to the control one. In cumulus cells, the expression of PFKM, PFKL, and G6PDH were increased following the addition of RJ to the maturation media. Supplementation of 10-mg/mL RJ to IVM medium increased the GPx mRNA abundance in both oocyte and cumulus cells and SOD expression in the cumulus cells. The CAT mRNA abundance was not influenced by the addition of RJ to the maturation media in either oocyte or cumulus cells. It seems that the improvement of oocyte maturation and its subsequent development in RJ₁₀ group may be associated with amelioration of redox status in the oocytes and activation of glucose metabolic pathways in their surrounding cumulus cells. This study involved multiple reactions and reactants, such as Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate (cas: 6413-10-1Application of 6413-10-1).

Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate (cas: 6413-10-1) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Dioxole functionalized metal-organic frameworks have also been recently reported.Application of 6413-10-1

Preparation and testing of ceasium Bronsted ion-exchanged Al-SBA-15 supported heteropoly acid as heterogeneous catalyst in the fructone fragrancy synthesis was written by Tran, Quang Vinh;Truong, Thi Hanh;Hung, Tran Quang;Doan, Huan V.;Pham, Xuan Nui;Le, Nam Thi Hoai;Bach, Long Giang;Nguyen, Van Tuyen.

Here we report a new ceasium Bronsted ion-exchanged Al-SBA-15 (Cs/AS15) supported heteropoly acid (HPA) H₃PW₁₂O₄₀ (HPA-Cs/AS15) material which can be prepared and used as heterogeneous catalyst for the fructone fragrancy synthesis. It was demonstrated that Cs⁺ was more effective than NH₄⁺ as counter cation of ion-exchanged AS15 support for preparing HPA/AS15 catalyst with higher acidity and HPA leaching stability. HPA-Cs/AS15 material showed high acidity with the maximum NH₃ desorption peak appeared at 759.6°C in the NH₃-TPD spectrum, stronger than pure HPA (635.7°C) and the ammonium Bronsted ion-exchanged Al-SBA-15 supported HPA (HPA-NH₄/AS15) (559.1°C) materials. The HPA leaching stability test showed that the HPA content of HPA-Cs/AS15 catalyst reduced only by 2.55% after five washing times, much less than that of HPA-NH₄/AS15 catalyst (49.22%). The higher acidity helped improve the HPA-Cs/AS15 catalyst performance in the fructone fragrancy synthesis. The Et acetoacetate conversion over this catalyst was 94.82%, better than those over HPA-NH₄/AS15 (93.49%) and pure HPA (89.52%) catalysts, although HPA-Cs/AS15 catalyst had lower HPA content (23.16 wt%) than HPA-NH₄/AS15 (24.28 wt%). In addition, it was shown that the reaction conditions such as Et acetoacetate:ethanediol reactant molar ratio of 1:1.5, ethanediol used as the diol reactant, and toluene used as the solvent, the fructone fragrancy synthesis reaction over HPA-Cs/AS15 catalyst reached the highest Et acetoacetate conversion (95.58%). The toluene’s boiling temperature of 110.6°C can promote the dispersion and contact abilities of the reactants with HPA mols. presented inside the pores of HPA-Cs/AS15 catalyst.
