Tai, Benjamin C. U. published the artcileSynthetic Poly(Vinylalcohol)-Based Membranes for Cartilage Surgery and Repair, Quality Control of 6346-09-4, the publication is Biotechnology Journal (2017), 12(12), n/a, database is CAplus and MEDLINE.

Cell-based therapies for cartilage repair are continually being developed to treat osteoarthritis. The cells are either introduced directly by intra-articular injection or via a cell-seeded matrix scaffold. Here, poly(vinylalc.)-based membranes are developed to be used for mesenchymal stem cell implantation in cartilage repair procedures, having controllable physicochem. properties such as porosity, mech. strength, and permeability, and a unique self-sealing property. The membranes possess a bilayer structure with a less porous layer providing mech. strength and selective permeability, exhibit an elastic modulus of between 0.3 and 0.9 MPa, and are permeable to mols. <40 kDa, which is in the range of cartilage permeability. Three different peptide ligands with the sequences Ac-GCGYGRGDSPG, Ac-GCG(OPG)4REGOFG(OPG)4, and Ac-GCG(OPG)7, resp., are conjugated to the membranes and subject to in vitro cell adhesion and differentiation assays. Col I/Col II gene expression ratios indicated that the collagen-mimetic peptide, Ac-GCG(OPG)7, best supported mesenchymal stem cell differentiation into the chondrogenic lineage. Although low retention of the membrane is observed in vivo in a rabbit knee model, results suggest that the membrane was able to facilitate mesenchymal stem cell implantation and differentiation to chondrocytes. These PVA-based membranes provide a feasible, synthetic, off-the-shelf material for the delivery of stem cells, and can be modified for other surgical applications.

Zhou, Jingwen published the artcileMetabolic engineering of microorganisms for vitamin C production, Computed Properties of 526-98-7, the publication is Subcellular Biochemistry (2012), 241-259, database is CAplus and MEDLINE.

A review. Vitamin C, an important organic acid, is widely used in the industries of pharmaceuticals, cosmetics, food, beverage and feed additives. Compared with the Reichstein method, biotechnol. production of vitamin C is an attractive approach due to the low cost and high product quality. In this chapter, biosynthesis of vitamin C, including one-step fermentation processes and two-step fermentation processes are discussed and compared. Furthermore, the prospects of the biotechnol. production of vitamin C are also presented.

Li, Jie published the artcileOptimum target plasma concentration of propofol in preventing adverse effects of carboprost tromethamine in patients undergoing caesarean section, Safety of 2-Amino-2-(hydroxymethyl)propane-1,3-diol (Z)-7-((1R,2R,3R,5S)-3,5-dihydroxy-2-((S,E)-3-hydroxy-3-methyloct-1-en-1-yl)cyclopentyl)hept-5-enoic acid, the publication is Zhonghua Mazuixue Zazhi (2016), 36(3), 321-324, database is CAplus.

Objective To investigate the optimum target plasma concentration of propofol in preventing the adverse effects of carboprost tromethamine in the patients undergoing caesarean section. Methods One hundred and twenty-eight nulliparous parturients who were at full term with a singleton fetus, of American Society of Anesthesiologists phys. status I or II, aged 24-37 yr, weighing 54-78 kg, scheduled for elective caesarean section under combined spinal-epidural anesthesia, were randomly divided into 4 groups (n = 32 each) using a random number table: control group (group C) and different concentrations of propofol groups (P_1-3 groups). Carboprost tromethamine 250 μg was injected into the body of the uterus, and propofol with the target plasma concentrations of 0.8, 1.2 and 1.6 μg/mL was simultaneously given by target-controlled infusion in P₁, P₂ and P₃ groups, resp., and normal saline was infused at a rate of 0.5 mL·kg^-1·h^-1 in group C. The occurrence of cardiovascular events was recorded from the end of carboprost tromethamine administration until the end of surgery. The related adverse effects after carboprost tromethamine administration and Ramsay sedation score at 15 mm after carboprost tromethamine administration were recorded, and satisfactory sedation was defined as Ramsay sedation score of 2. The occurrence of complications associated with combined spinal-epidural anesthesia was recorded during the postoperative follow-up. Results Compared with group C, the incidence of carboprost tromethamine-related adverse effects was significantly decreased in P₂ and P₃ groups, the rate of satisfactory sedation was significantly increased in P₁ and P₂ groups, the incidence of hypotension and tachycardia was significantly decreased in group P₁ (P<0.05), and no significant change was found in the incidence of carboprost tromethamine-related adverse effects in group P₁ and in the rate of satisfactory sedation in group P₃ (P>0.05). Compared with group P₁, the incidence of carboprost tromethamine-related adverse effects was significantly decreased in P₂ and P₃ groups, the rate of satisfactory sedation was significantly increased in group P₂, and the rate of satisfactory sedation was significantly decreased in group P₃ (P<0.05). Compared with group P₂, the rate of satisfactory sedation was significantly decreased (P<0.05), and no significant change was found in the incidence of carboprost tromethamine-related adverse effects in group P₃ (P>0.05). No cardiovascular events were found in group P₂, and the incidence of hypotension was 9% in group P₃. Conclusion The optimum target plasma concentration of propofol in preventing the adverse effects of carboprost tromethamine is 1.2 μg/mL in the patients undergoing caesarean section.

Porous organic cages (POCs) have attracted extensive attention due to their unique structures and tremendous application potential in numerous areas. In this study, an enantioselective potentiometric sensor composed of a polyvinyl chloride (PVC) membrane electrode modified with CC3-R POC material was used for the recognition of enantiomers of 2-amino-1-butanol. After optimization, the developed sensor exhibited enantioselectivity toward S-2-amino-1-butanol (log KPotS,R = -0.98) with acceptable sensitivity, and a near-Nernstian response of 25.8 ± 0.3 mV/decade within a pH range of 6.0-9.0.

Kassie, Abebu A. published the artcileSynthesis and Reactivity of Zr MOFs Assembled from P^NN^NP-Ru Pincer Complexes, Recommanded Product: Triethylsilanol, the publication is Organometallics (2019), 38(18), 3419-3428, database is CAplus.

Three isostructural Zr metal-organic frameworks were synthesized from P^NN^NP-Ru pincer metallolinkers bearing different combinations of ancillary ligands (1, Zr₆O₄(OH)₄(OAc)₄{cis-(P^NN^NP)RuCl₂(CO)}₂; 2, Zr₆O₄(OH)₄(O₂CH)₄{(P^NN^NP)RuCl(CO)₂}₂Cl₂; 3, Zr₆O₄(OH)₄(OAc)₄{cis-/trans-(P^NN^NP)RuCl₂(CO)}₂; P^NN^NP = 2,6-(HNPAr₂)₂C₅H₃N; Ar = p-C₆H₄CO₂^–). The structure and composition of the P^NN^NP-Ru pincer MOFs were determined using synchrotron X-ray powder diffraction, solid- and solution-state NMR spectroscopy, IR spectroscopy, and elemental anal. Reaction of 2 with KO^tBu results in deprotonation of an NH group of the P^NN^NP-RuCl(CO)₂ linkers. Subsequent treatment with Me₃NO removes a Ru-coordinated CO ligand, generating 2–b (5), which proved to be a recyclable catalyst for the hydrosilylation of aryl aldehydes with Et₃SiH. A similar postsynthetic treatment of 1 and 3 does not generate active catalysts, highlighting the importance of precatalyst design and activation. A homogeneous analog of 2–b also showed inferior catalytic performance, demonstrating the benefit of catalyst immobilization.

Yang, Pipeng published the artcileResonance energies and tautomerism of substituted aromatic heterocycles and their benzo derivatives, COA of Formula: C4H4OS, the publication is Youji Huaxue (1991), 11(6), 620-3, database is CAplus.

The recently developed quantified resonance theory (QRT) has been applied to substituted aromatic five- and six-membered heterocycles and their benzo derivatives The calculated resonance energy differences ΔRE between tautomeric forms agree with those estimated from tautomeric equilibrium data for the 2- and 4-pyridone, 2-quinolone and 1-isoquinolone series. For tautomerism of extensive heteroaromatic compounds in solution, the ΔRE and the differences in heats of atomization ΔΔH₃ calculated by QRT can be used to rationalize and predict the predominant tautomer and the shifting trend in the equilibrium for a series of similar compounds
