“To determine whether monitoring follicle stimulating hormone (FSH) levels in over-responding patients whom the gonadotropins were withheld would predict pregnancy outcome.
A group of 33 female infertility patients aged between 20-40 years who had to be coasted during controlled ovarian hyperstimulation were recruited for this study. The FSH concentrations on human chorionic gonadotropin (HCG) day and on the four preceding days were measured to determine the threshold FSH concentration for follicular growth and conception. Mean and this website standard deviation were used for presenting parametric data. Student’s t test and the Mann Whitney U test were used for statistical analysis. Two-tailed P < 0.05 was taken as significant. Receiver-operating characteristic (ROC) curves were performed to identify the cutoff level for FSH and E2 at HCG day and four preceding days.
Of 33 cycles, 16 were stimulated with recombinant FSH and 17 with recombinant FSH and human menopausal gonadotropin (HMG). The basal and mean coasting FSH levels of FSH and
FSH + HMG cycles did not reveal any differences. FSH concentrations decreased the day after coasting began in 26 cycles and fell by 30.2 +/- A 2.7% (range 2-53). In 7 cycles, we observed 34.5 +/- A 7.4% (range 6-56) declines in FSH levels beginning 2 days after coasting. Of the 31 women who received HCG, 21 conceived during in vitro fertilization and embryo transfer (IVF-ET). Gestational sac and fetal selleck heart activity were visualized in 14 patients. ROC analysis releaved a cutoff value of 4.9 in FSH level at HCG day discriminative of conception or nonconception.
The results from this study show that monitoring
serum FSH levels during coasting may be helpful in predicting the pregnancy outcome.”
“Highly branched poly(N-isopropylacrylamide) (PNIPAM) has been synthesized by a reversible addition-fragmentation chain transfer (RAFT) copolymerization SHP099 of NIPAM and a vinyl contained trithiocarbonate RAFT agent. (1)H-NMR measurements revealed that the degrees of branch (DB) are in the range of 0.032-0.105. Laser light scattering (LLS) measurements gave the hydrodynamic radii (Rh) of the polymers to be 3.6-5.7 nm with molecular weight in the range of 1.3 x 10(4) g/mo1-2.3 x 10(-4) g/mol. Highly branched PNIPAM with terminal thiol groups were obtained by aminolysis the polymers, and the product can be oxidized by air to form disulfide bonds (-S-S-) among chains and resulting in the formation of nanoparticle in aqueous solution. Interestingly, the nanoparticle in size of R(h) (similar to) 80 nm showed a thermogelling behavior to form bulk hydrogel when the temperature was increased up to 25 degrees C due to the thermo-induced association of the PNIPAM chains among the nanoparticles.
