A recent survey of the Cambridge Structural Database, CSD [Allen (2002). Acta Cryst. B58, 380-388], shows that the percentage of incorrect assignments of the space group Cc has remained at about 10% since the last survey in 1997.

‎A finite group $G$ is called a $CC$-group ($Gin CC$) if the centralizer of each noncentral element of $G$ is cyclic‎. ‎In this article we determine all finite $CC$-groups.

background: clomiphene citrate (cc) an agonist and antagonist of estrogen, is the first line treatment in ovarian stimulation. anti-estrogenic effect of cc in endometrial thickness and cervical mucus has negative effect on pregnancy rate. letrozole is an aromatase inhibitor has been seen that has acceptable pregnancy rate compared to cc. objective: the aim of this study was to compare the effic...

Background: Different protocols are used for controlled ovarian hyper stimulation (COH), but the optimal method has not yet been determined. So we decided to compare the outcome of controlled ovarian stimulation using clomiphen citrate +HMG versus clomiphen citrate +rFSH in IUI cycles. Materials and Methods: 144 women with unexplained or male factor infertility undergoing IUI cycles (72 patient...

there are currently ‎many different protocols in use for controlled ovarian hyperstimulation (coh), but the optimal method has ‎not yet been determined. to compare the outcome of coh using ‎clomiphene citrate (cc) versus cc plus human menopausal gonadotropin (hmg) in conjunction with intrauterine insemination (iui), we studied 117 infertile couples‎. iui with cc was used in 92 cycles ‎(group a)...

background: different protocols are used for controlled ovarian hyper stimulation (coh), but the optimal method has not yet been determined. objective: the aim of this study was to compare the outcome of controlled ovarian stimulation (cos) using clomiphen citrate (cc) plus hmg versus cc plus rfsh in intra uterine insemination cycles (iui). materials and methods: 144 women with unexplained or m...

In order to evaluate the effects of short course administration of dexamethasone (DEX) combined with clomiphene citrate (CC) in CC-resistant patients with polycystic ovary syndrome (PCaS) and normal DHEAS, a prospective, double blind, placebo controlled, randomized study was undertaken at referral university hospitals, Two-hundred and thirty women with PCOS and normal DHEAS who failed to ...

Background To compare two different gonadotropin preparations, human menopausal gonadotropin (hMG) and recombinant follicle-stimulating hormone (rFSH), combined with clomiphene citrate (CC) in women with unexplained infertility undergoing intrauterine insemination (IUI). MaterialsAndMethods In this prospective clinical trial, couples prepared for IUI cycles were randomly allocated to two groups...
