Do all tannins have similar nutritional effects? A comparison of three Brazilian fodder legumes
(Elsevier B.V., 2005-04-04)
Three tropical legumes, namely Leucaena leucocephala, Sesbania sesban and Cajanus cajan, were subjected to chemical analysis plus in vitro, in situ and in vivo evaluations. Three different assays were used to determine ...
Cyclic amines homobimetallic ruthenium pre-catalysts bearing bidentate phosphine and their dual catalytic activity for the ring-opening metathesis and atom-radical polymerizations
(2019-12-15)
A series of [RuCl(dppb)(μ-Cl)3Ru(dppb)(amine)] complexes, where amine is pyrrolidine (1), piperidine (2) or perhydroazepine (3), were synthesized and characterized by elemental analysis, FTIR, UV–Vis, and 1H, 13C{1H} and ...
Dual catalytic performance of arene-ruthenium amine complexes for norbornene ring-opening metathesis and methyl methacrylate atom-transfer radical polymerizations
(2020-05-01)
Arene ruthenium(II) complexes bearing the cyclic amines RuCl2(η6-p-cymene)(pyrrolidine)] (1), [RuCl2(η6-p-cymene)(piperidine)] (2), and [RuCl2(η6-p-cymene)(peridroazepine)] (3) were successfully synthesized. Complexes 1–3 ...
Neonicotinic analogues: Selective antagonists for a4b2 nicotinic acetylcholine receptors
(Elsevier, 2013)
Nicotine is an agonist of nicotinic acetylcholine receptors (nAChRs)that has been extensively used as a
template for the synthesis of a4b2-prefer ring nAChRs.Here,we used the N-methyl-pyrrolidine moiety
of nicotine to ...

Effect of TNF-alpha on molecules related to the Iinsulin action in endometrial cells exposed to hyperandrogenic and hyperinsulinic conditions characteristics of polycystic ovary syndrome
(Sage, 2018)
Polycystic ovary syndrome (PCOS) affects not only ovarian functions but is also able to affect endometrium metabolism. Around 80% of women with PCOS are obese. High tumor necrosis factor (TNF)- production and low adiponectin ...
Separation and preconcentration of inorganic Se species in tap and natural waters using unfunctionalized nanosilica as sorption material in dispersive micro-solid phase extraction
(Elsevier Science, 2019-01)
A highly sensitive and selective method based on dispersive micro-solid phase extraction (D-μ-SPE) technique was developed for the determination of inorganic Se species. A very simple and fast preconcentration procedure ...
Poly(ester)s and poly(amide)s with fluorene and diphenyl-silane units in the main chain: Effects of iodine doping on the structure and electrical conductivity
(2012)
Intramolecular charge transfer interaction between the electron donor and electro acceptor units within the polymeric structure and its optoelectronic properties were studied. The monomer, 9H-fluorene-2,7-dicarboxylic acid, ...
