BACKGROUND Hyperandrogenism and insulin resistance may be related to the etiology of PCOS. Zucker fa/fa rats with polycystic ovary are obese, have insulin resistance without diabetes mellitus or hyperandrogenism and can be utilized as PCOS model rats without effects of hyperandrogenemia. PCOS patients are reported to have elevated levels of serum anti-Mullerian hormone (AMH), which has an inhib...

BACKGROUND Phenylephrine use has been recommended over ephedrine for the management of hypotension after spinal anesthesia for elective caesarean section. The evidence for this is rather limited because in previous trials, pH was significantly lower after ephedrine, but absolute values were still within normal range. We pooled the available data to define maternal and neonatal effects of the tw...

OBJECTIVE To evaluate the efficacy of 0.9% bromfenac (Xibrom™) or a celecoxib-impregnated intraocular lens (celecoxib-IOL) compared with 1% prednisolone acetate (PA) in controlling postoperative inflammation and posterior capsule opacification (PCO). ANIMAL STUDIED Fifty-nine dogs undergoing cataract extraction by phacoemulsification. PROCEDURE Bilateral patients received bromfenac or celec...

The marine diazotrophic cyanobacterium Trichodesmium responds to elevated atmospheric CO(2) partial pressure (pCO(2)) with higher N(2) fixation and growth rates. To unveil the underlying mechanisms, we examined the combined influence of pCO(2) (150 and 900 microatm) and light (50 and 200 micromol photons m(-2) s(-1)) on Trichodesmium IMS101. We expand on a complementary study that demonstrated ...

This study was conducted in order to clarify whether photocatalyst flocculation--as observed in biologically pretreated greywater--contributes to photocatalytic oxidation (PCO) efficiency impairment. Aqueous solutions of tetraethyleneglycol dimethylether spiked with different inorganic salts in concentrations as found in biologically treated greywater were investigated with respect to TiO2 floc...

The biological diagnosis of polycystic ovary syndrome (PCO) remains questionable, and a single immunological hLH (ihLH) determination can be misleading. In order better to characterize these patients, we studied hLH pulsatility every 10 min for 4h using a radioimmunoassay and then compared the results with others we obtained with a biological method. Radioimmunological and biological profiles w...

PURPOSE While cataract surgery initially benefits most patients, many suffer secondary loss of vision because of posterior capsule opacification (PCO). Lens epithelial cells left behind at surgery become aberrant and migrate into the light path. TGF-beta (TGFbeta) appears to play a key role in this process by inducing the cells to undergo an epithelial-mesenchymal transition. Paradoxically, it ...

1120-6721/435-07$25.00/0 © Wichtig Editore, 2008 PURPOSE. To evaluate the influence of posterior capsular opacification (PCO) on macular optical coherence tomography (OCT) imaging quality and measurements of macular retinal thickness. METHODS. In this prospective interventional case series, 32 eyes of 23 patients with PCO were recruited. Best-corrected visual acuity (BCVA), a complete ophthalmo...

Abstract Background Patient care ownership (PCO) is an essential component in medical professionalism and crucial for delivering high-quality care. The 15-item PCO Scale (PCOS) a validated questionnaire quantifying residents; however, no corresponding tool assessing Japan exists. This study aimed to develop Japanese version of the PCOS (J-PCOS) validate it among trainees. Methods We performed m...
