background: in recent years, the high likelihood of the implantation of transferred embryos has led to an increase in the number of multiple pregnancies and consequently an increased risk of complications in fetuses and mothers. since the aim of infertility treatment is the birth of a healthy child while preserving the mother’s health, therefore, attempts should be made to avoid multiple pregna...

background: more and more infertile patients have accepted the assisted reproductive technique (art) therapy. concerns have been raised over an increased risk of adverse maternal outcomes in art populations as compared with natural conception (nc). objective: the aim was to improve the art in clinicial work and to reduce the incidence of pregnancy complications in art group according to analyzi...

Substrate activation by means of a reactive ligand is a topic of much interest. Herein we describe a stoichiometric anti-Markovnikov C-N bond formation involving ligand reactivity in multiple steps along the reaction coordinate, including ligand assisted substrate (de)protonation and C-N bond formation, as illustrated by a combined experimental, spectroscopic and computational study. This affor...

The Rh-catalyzed CO hydrogenation to hydrocarbons and C2-oxygenates over Rh/ZrO2 Rh/SiO2 was studied. Catalytic reaction tests show a support effect with faster steady state rate compared Rh/SiO2. Temperature programmed (TPH) experiments reveal that the dissociation on metal surface is limiting, thus accelerates metal. Combined TPH diffuse reflectance infrared Fourier transform spectroscopy (DR...

background: transforming growth factor-beta (tgf-β) activation appears to be crucial for tissue injury in diabetic nephropathy (dn). fibromodulin, the small leucine-rich proteoglycan, has been proposed to be the potent tgf-β modulator. in this study, the therapeutic effects of fibromodulin in the kidneys of streptozotocin (stz)-induced diabetic rats were investigated. methods: diabetic rats rec...

The development of a ligand-assisted Pd-catalyzed C–H alkenylation of aliphatic amines is reported. Our studies indicated that an amino-acid-derived ligand renders the C–H bond activation step reversible and promotes the traditionally difficult alkenylation process. The C(sp)–H alkenylation proceeds through a 5-membered-ring cyclopalladation pathway that allows access to complex aliphatic heter...

(1R*,4S*,4aR*,9aS*,10S*)-10-Hydroxy-10-phenyl-1,4a,9a,10-tetrahydro-1,4-methanoanthracen-9(4H)-one (1c) was prepared for the elucidation of the reaction mechanism of intramolecular hydroalkoxylation of alkenes catalyzed by gold nanoclusters stabilized by a hydrophilic polymer, poly(N-vinyl-2-pyrrolidone) (Au:PVP). It was found that the reaction proceeded via anti-addition of alcohol to the alke...

In this study, we synthesized various dimensionalities of ZnO nanowires using the Ti grid-assisted chemical vapor deposition process. Energy dispersive X-ray spectroscopic mapping technique accompanied with a lattice diffusion model was used to characterize the growth mechanism. A diffusion ratio γ, defined by short-circuit and lattice diffusion activation energies, was obtained to describe the...
