The present paper is to deliberate the class of $3$-dimensional trans-Sasakian manifolds which admits $\eta$-Einstein solitons. We have studied solitons on where Ricci tensors are Codazzi type and cyclic parallel. also discussed some curvature conditions admitting vector field torse-forming. shown an example manifold with respect soliton verify our results.

Purpose Low molecular weight iron(III) complex-based contrast agents (IBCA) including trans-cyclohexane diamine tetraacetic acid [Fe(tCDTA)]? could serve as alternatives to gadolinium-based in MRI. In search for IBCA with enhanced properties, we synthesized derivatives of and compared their effects. Methods Trans-cyclohexane (tCDTA) was chemically modified 2 steps: first the monoanhydride gener...

Amyloid-β (Aβ) self-assembly into cross-β amyloidfibrils is implicated in a causative role in Alzheimer’s disease pathology.Uncertainties persist regarding the mechanisms of amyloid self assembly and the role of metastable prefibrillar aggregates. Aβ fibrilsfeature a sheet-turn-sheet motif in the constituent β-strands; as such, turn nucleation has been proposed as a rate-limiting step in the se...

The physical and biological properties have been determined for three Pt(IV) complexes with trans amine ligands: trans,trans,trans-[PtCl(2)(OH)(2)(dimethylamine)(isopropylamine)] (1(IV)), trans,trans,trans-[PtCl(2)(OH)(2)(dimethylamine)(methylamine)] (2(IV)) and trans,trans,trans-[PtCl(2)(OH)(2)(isopropylamine)(methylamine)] (3(IV)). The crystal structures of 2(IV) and 3(IV) reveal substantial ...

1'-Diphenylphosphino-1-{[(2-(methylthio)ethyl)amino]carbonyl}ferrocene (1), accessible via amidation of 1'-(diphenylphosphino)ferrocene-1-carboxylic acid (Hdpf) with 2-(methylthio)ethylamine, reacts with [PdCl2(cod)] (cod = cycloocta-1,5-diene) at a 1 : 1 metal-to-ligand ratio to give trans-[PdCl2(1-κ(2)P,S)] (trans-2) as the sole product. A similar reaction with [PtCl2(cod)] affords a mixture ...

The frustrated Lewis pair B(C(6)F(5))(3)/P(o-tolyl)(3) (4a) reacts with 4,6-decadiyne to give the trans-1,2-addition product 5. In contrast, the B(C(6)F(5))(3)/P(t)Bu(3) FLP (4b) reacts with this substrate to give the trans-1,4-adduct trans-6. The cumulene trans-6 undergoes trans-/cis-isomerization upon photolysis to give a ca. 1:1 trans-6/cis-6 mixture. The FLP 4b reacts with 2,6-hexadiyne at ...

Trans-3'-hydroxycotinine is a major metabolite of nicotine in humans and is mainly excreted as O-glucuronide in smoker's urine. Incubation of human liver microsomes with UDP-glucuronic acid produces not only trans-3'-hydroxycotinine O-glucuronide but also N-glucuronide. The formation of N-glucuronide exceeds the formation of O-glucuronide in most human liver microsomes, although N-glucuronide h...

1. The seven isomeric optically inactive forms of methylcyclohexanol (i.e. 1-, and cis- and trans-2-, -3- and -4-) are excreted by rabbits mainly as glucuronides of the thermodynamically more stable forms of the alcohols. The eighth isomer, cyclohexylmethanol, however, undergoes aromatization in vivo, giving rise to benzoic acid and hippuric acid. The (+/-)-2-, (+/--3- and 4-methylcyclohexanone...
