BACKGROUND Clomiphene is the current first-line infertility treatment in women with the polycystic ovary syndrome, but aromatase inhibitors, including letrozole, might result in better pregnancy outcomes. METHODS In this double-blind, multicenter trial, we randomly assigned 750 women, in a 1:1 ratio, to receive letrozole or clomiphene for up to five treatment cycles, with visits to determine ...
BACKGROUND Clomiphene citrate is one of the effective drugs for infertility treatment due to oligo-ovulation or anovulation. Intrauterine insemination (IUI) is one of more adherent methods for treatment of infertile cases which is followed by controlled ovarian hyperstimulation (COH). OBJECTIVE the aim of this study was to evaluate Clomiphene citrate versus letrozole with gonadotropins in IUI...
Biochemically based models of C(3) photosynthesis can be used to predict that when photosynthesis is limited by the amount of Rubisco, increasing atmospheric CO(2) partial pressure (pCO(2)) will increase light-saturated linear electron flow through photosystem II (J(t)). This is because the stimulation of electron flow to the photosynthetic carbon reduction cycle (J(c)) will be greater than the...
Post-operative capsular opacification is a multifactorial physiological consequence of cataract surgery. Opacification involving the central posterior capsule has a significant impact on high and low contrast acuity and low contrast sensitivity. The assessment of Posterior Capsule Opacification (PCO) on cadaver eyes, experimental studies, culture models and in clinical studies has provided an u...
Purpose: A review of posterior capsule opacification (PCO) after cataract surgery and some affecting factors Methods: A cross-sectional study was designed to study cataract patients who underwent cataract surgery between 2003 and 2006 in Farabi Eye Hospital, Tehran, Iran. Random sampling was done. Those with a history of uveitis, intraocular surgery, and eye trauma were excluded from the study....
PURPOSE To evaluate the incidence of posterior capsule opacification (PCO) four years after the implantation of a hydrophilic acrylic intraocular lens (IOL). METHODS Fifty-eight randomly selected eyes from 58 patients were analyzed four years after phacoemulsification and Ioflex IOL implantation. The patients underwent an ophthalmic examination to detect PCO and a detailed medical history was...
Episodic events like hurricanes, storms and frontal- and eddy-driven upwelling can alter the partial pressure of CO(2) (pCO(2)) at the sea surface by entraining subsurface waters into the surface mixed layer (ML) of the ocean. Since pCO(2) is a function of total dissolved inorganic carbon (DIC), temperature (T), salinity and alkalinity, it responds to the combined impacts of physical, chemical ...
We investigated the tissue regeneration and lipid-lowering effects of policosanol (PCO) by employing a hyperlipidemic zebrafish model. A reconstituted high-density lipoprotein containing policosanol (PCO-rHDL) facilitated greater cell growth and replication with less apoptosis and reactive oxygen species (ROS) production in BV-2 microglial cell lines. From in vivo study, injection of rHDL conta...
Background: For more than four decades clomiphene citrate has been the first line of the treatment for ovulatory disorders. The aim of this study was to compare the effects of letrozole and clomiphene citrate on ovulation and pregnancy rate in patients with polycystic ovary syndrome. Methods: In this prospective double-blind study, 100 patients with polycystic ovary syndrome were randomized int...
BACKGROUND Polycystic ovaries (PCO) and their clinical expression (the polycystic ovary syndrome [PCOS]) as well as type 2 diabetes mellitus (T2DM) are common medical conditions linked through insulin resistance. We studied the prevalence of PCO and PCOS in women with diet and/or oral hypoglycemic treated T2DM and non-diabetic control women. DESIGN Prospective study. METHODS One hundred and...
