Reaction of the doubly-bridged biscyclopentadienes (C5H4(EMe2))(C5H4(SiMe2)) (E = Si(1a), or C(1b)) with Re2(CO)10 in refluxing mesitylene gave the corresponding dirhenium carbonyl complexes [(η(5)-C5H3)2(EMe2)(SiMe2)][Re(CO)3]2 (trans-2a,b and cis-2a,b), and the desilylated products [(η(5)-C5H4)2(EMe2)][Re(CO)3]2 (3a,b). Photolysis of trans-2a,b with a series of aryl halides in benzene results...

Severe physical activity leads to a sharp increase in free radicals, an oxidative stress, inflammation, and tissue damage. Resveratrol as one of the antioxidants can be effective in preventing the effects of oxidative stress. Therefore, the present study was aimed to evaluate the effect of trans-resveratrol supplementation and training exercise on inflammation-related factors. Sixty-four ...

26 Based on the potential benefits for long-term human health there is interest in 27 developing sustainable nutritional strategies for lowering medium-chain saturated 28 fatty acids (FA) and increasing specific unsaturated FA in ruminant milk. Dietary 29 supplements of extruded linseeds (EL), fish oil (FO) or a mixture of EL and FO 30 increase cis-9, trans-11 conjugated linoleic acid (CLA) and...

The mechanism of substitution water exchange reactions in square planar trans-Pt[(NH(3))(2)T(H(2)O)](n+) complexes is studied (T = H(2)O, NH(3), OH(-), F(-), Cl(-), Br(-), H(2)S, CH(3)S(-), SCN(-), CN(-), PH(3), CO, CH(3)(-), H(-), C(2)H(4)). The trans effect is explained in terms of sigma-donation and pi-back-donation whose relative strengths are quantified by the changes of electron occupatio...

A novel series of (3-diethoxyphosphoryl)isoxazolidines substituted at C5 with various quinazolinones have been synthesized by the 1,3-dipolar cycloaddition of N-methyl-C-(diethoxyphosphoryl)nitrone with N3-substitued 2-vinyl-3H-quinazolin-4-ones. All isoxazolidines were assessed for antiviral activity against a broad range of DNA and RNA viruses. Isoxazolidines trans-11f/cis-11f (90:10), trans-...

The furan ring in the title compound, C(26)H(17)BrN(2)O(2), adopts a twisted envelope conformation. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O inter-action which generates an S(6) ring motif. The crystal packing is stabilized by N-H⋯O and C-H⋯Br inter-actions, generating an R(2) (2)(16) ring motif and a C(12) linear chain motif, respectively. Weak C-H⋯π bonding is also o...

to improve visual disturbance, optic nerve decompression can be performed via transcranial or tran-sphenoidal approaches. although the surgical exposure in transcranial approach is favourable, yet the optic nerve's presence in the field may make it vulnerable to damage. of fighty patients with different types of pituitary adenomas, 35 cases with medium-sized (1-3 cm) tumors have been studi...

The cis and trans racemates of synthetic 3-hydroxyproline and of synthetic 3-methoxyproline were interconverted by an epimerization reaction at carbon atom 2. The interconversions are proof of the diastereomeric nature of the synthetic isomers. Assignments of cis and trans configuration were made from nuclear magnetic resonance studies. Synthetic cisand trans-3-hydroxy-DL-proline were partially...
