Gene ontology analysis of expanded porcine blastocysts from gilts fed organic or inorganic selenium combined with pyridoxine

Background: Gene ontology analysis using the microarray database generated in a previous study by this laboratory was used to further evaluate how maternal dietary supplementation with pyridoxine combined with different sources of selenium (Se) affected global gene expression of expanded porcine blastocysts. Data were generated from 18 gilts randomly assigned to one of three experimental diets (n=6 per treatment): i) basal diet without supplemental Se or pyridoxine (CONT); ii) CONT +0.3 mg/kg of Na-selenite and 10mg/kg of HCl-pyridoxine (MSeB(6)10); and iii) CONT +0.3mg/kg of Se-enriched yeast and 10 mg/kg of HCl-pyridoxine (OSeB(6)10). All gilts were inseminated at their fifth post-pubertal estrus and euthanized 5days later for embryo harvesting. Differential gene expression between MSeB(6)10 vs CONT, OSeB(6)10 vs CONT and OSeB(6)10 vs MSeB(6)10 was performed using a porcine embryo-specific microarray. Results: There were 559, 2458, and 1547 differentially expressed genes for MSeB(6)10 vs CONT, OSeB(6)10 vs CONT and OSeB(6)10 vs MSeB(6)10, respectively. MSeB(6)10 vs CONT stimulated 13 biological processes with a strict effect on RNA binding and translation initiation. OSeB(6)10 vs CONT and OSeB(6)10 vs MSeB(6)10 impacted 188 and 66 biological processes, respectively, with very similar effects on genome stability, ceramide biosynthesis, protein trafficking and epigenetic events. The stimulation of genes related with these processes was confirmed by quantitative real-time RT-PCR. Conclusions: Gene expression of embryos from OSeB(6)10 supplemented gilts was more impacted than those from MSeB(6)10 supplemented gilts. Whereas maternal OSeB(6)10 supplementation influenced crucial aspects of embryo development, maternal MSeB(6)10 supplementation was restricted to binding activity.

Solubility Enhancement of Vitamins in Water in the Presence of Covitamins: Measurements and ePC-SAFT Predictions

Scarce knowledge on the behavior of vitamins in aqueous solutions in the presence of additives is often a limiting factor for industrial applications such as process design and optimization. Knowing the pH-solubility profiles of vitamins is fundamental for understanding and controlling their behavior in aqueous solutions. In the present work, pH-dependent solubilities of the vitamins ascorbic acid (VC), riboflavin (VB2), nicotinic acid (VB3(acid)), folic acid (VB9), and cyanocobalamin (VB12) were measured at T = 298.15 K and p = 1 bar. These results were compared to the pH-solubility profiles obtained with modified Henderson-Hasselbalch equations using pK(a) values from the literature. Further, the solubilities of poorly soluble VB2, VB9, and VB12 were increased by the addition of covitamins VC, VB3(acid), and nicotinamide (VB3(acid)). As observed, VB3(amide )increases the vitamin solubility much stronger than VC and VB3(acid). These covitamins are called hydrotropes in several works in the literature, and they increase the solubility of other vitamins by manipulating the pH of the saturated solutions and by molecular cross-interactions. The interplay between both pH and cross-interactions depends strongly on the kind and concentration of covitamin. At low concentrations, VC and VB3(amide) (<0.2 m) increased solubility by pH change. At higher concentrations of VC and VB3(amide) added, mainly cross-interactions between vitamin and covitamin determine the strength of solubility increase. To separate these effects and to further reduce experimental effort, electrolyte perturbed-chain statistical association fluid theory was used to predict vitamin solubility. The pH-solubility profiles and the solubilities of vitamins in water at T = 298.15 K and p = 1 bar upon addition of covitamins were predicted with reasonable accuracy. This success resulted from accounting for different charged and neutral vitamin species according to the pH and from considering explicitly the vitamin- water and vitamin-covitamin interactions. It could be shown that hydrotropic solubilization of a vitamin is the increase of vitamin solubility caused by pH shift and by cross-interactions between the saturated species of a vitamin and the added covitamin.

Multi-functional electrochemiluminescence aptasensor based on resonance energy transfer between Au nanoparticles and lanthanum ion-doped cadmium sulfide quantum dots

Novel lanthanum ion-doped cadmium sulfide quantum dots (CdS:La QDs) were synthesized and characterized by transmission electron microscopy (TEM) and photoluminescence (PL). Based on CdS:La QDs as the electrochemiluminescence (ECL) luminophores, a distance-dependent ECL intensity enhanced or quenched system between CdS:La QDs and gold nanoparticles (Au NPs) was designed. Firstly, ssDNA 1 was linked to the CdS:La QDs modified glassy carbon electrode via amide bond. Then the prepared Au NP – ssDNA 2 conjugates were used to hybridize with ssDNA 1, the surface plasmon resonances (SPR) of Au NPs enhanced ECL intensity (signal on) while Au NPs and CdS:La QDs were separated at a certain distance. Secondly, In the presence of Hg2+, the oligonucleotide conformation changed from linear chain to hairpin due to the thymine-Hg2+-thymine (T-Hg2+-T) base pairs. ECL quenching (signal off) achieved lie in resonance energy transfer (RET) between the CdS:La QDs and the proximal Au NPs at a close distance. Finally, after being incubated with TB, a strong and stable TB-aptamer complex was generated, which led to the release of Au NP-ssDNA 2 conjugates. The ECL signal of the CdS:La QDs was ultimately recovered (signal on again). The on-off-on approach was used to detect Hg2+ and TB, sensitively and respectively. The line ranges were 1.00 x 10(-12)-1.00 x 10(-5) mol L-1 and 1.00 x 10(-16) – 1.00 x 10(-6) mol L-1 respectively. The low limits of detection (S/N = 3) were at 3.00 x 10(-13) mol L-1 and 3.00 x 10(-17) mol L-1. Moreover, the ECL sensor exhibited high selectivity and good stability, and was successfully applied to the detection of TB in real sample. (C) 2019 Elsevier B.V. All rights reserved.

Adding some certain compound to certain chemical reactions, such as: 62009-47-6, name is 2-Aminomalonamide, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 62009-47-6. 62009-47-6

Diethylaminomalonate Aminomalondiamide 2-Carbamido-3-hydroxypynazine To an aqueous solution of diethylaminomalonate (hydrochloride form) was added sodium hydrogenocarbonate (pH> 7). After extraction, the organic phase was evaporated under reduced pressure and treated with an ammoniacal solution of methanol at 80C overnight to give aminomalondiamide quantitatively. This compound was used for next step without purification and dissolved in water. To that solution was added glyoxal sodium bisulfite hemihydrate, this reaction mixture was stirred at 90C for 3h, and then made basic with 58% NH4OH. Then, 30% H2O2 was added dropwise with rapid stirring to the cold solution (0C) [J. Med. Chem. 1983, 26, 283-86, J. Heterocyclic Chem. 1979, 16, 193]. The reaction mixture was allowed to warm at room temperature and the desired 2-hydroxy-3- carboxamidopyrazine precipitated. The solid was collected (63% yield) and part of it recrystallized.

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 2-Aminomalonamide.
