OBJECTIVE Pulse contour analysis can be used to provide beat-to-beat cardiac output (CO) measurement. The current study sought to evaluate this technique by comparing its results with lithium dilution CO (LiCO) measurements. DESIGN Prospective, observational study. SETTING Surgical intensive care unit. PATIENTS Twenty-two patients after cardiac or major noncardiac surgery. MEASUREMENTS ...

BACKGROUND Anti-Mullerian hormone (AMH) is expressed in pre- and small-antral follicles. High serum levels are found in women with polycystic ovaries (PCO), accordant with their increased content of small follicles. To evaluate the relationship between AMH, folliculogenesis and hyperandrogenism, we compared serum AMH levels between women with PCO with and without hyperandrogenism and normal con...

The severity of the impact of elevated atmospheric pCO 2 to coral reef ecosystems depends, in part, on how seawater pCO 2 affects the balance between calcification and dissolution of carbonate sediments. Presently, there are insufficient published data that relate concentrations of pCO 2 and CO 2− 3 to in situ rates of reef calcification in natural settings to accurately predict the impact of e...

PURPOSE We investigated the effect of epidermal growth factor receptor (EGFR) siRNA on human lens epithelium (HLE) cells and the development of posterior capsular opacity (PCO). METHODS We designed EGFR siRNA and used it to knockdown the expression of EGFR in HLE cells. Cell proliferation was examined by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), cell growth curve ass...

PURPOSE This meta-analysis aims to evaluate the differences in performance of posterior capsular opacification (PCO) between hydrophobic acrylic intraocular lens (IOLs) and hydrophilic acrylic IOLs. SETTING Tianjin Medical University, Tianjin Eye Hospital, Tianjin Key Laboratory of Ophthalmology and Visual Science, Tianjin, China. DESIGN Systematic review of randomized controlled trials (RC...

Posterior capsule opacification (PCO) is the most common long-term complication with more than 25% overall incidence within 5 years after cataract surgery of the human eye. The goal of the project described in this paper is to devise a fully automated, objective measure of grades of PCO from so-called retroillumination photographs. We review the current state of the art of existing PCO grading ...

As pre-launch antenna calibrations are not available for GPS and GLONASS satellites, the high correlation between terrestrial scale phase center offset (PCO) prevents a reliable estimation of with GNSS (Global Navigation Satellite System) technology. Fortunately, ground calibrated PCO values Galileo, BeiDou navigation satellite system (BDS), QZSS have been released, making possible. In third re...

Principal component analysis (PCA) and its dual—principal coordinate analysis (PCO)—are widely applied to unsupervised dimensionality reduction. In this paper, we show that PCA and PCO can be carried out under regression frameworks. Thus, it is convenient to incorporate sparse techniques into the regression frameworks. In particular, we propose a sparse PCA model and a sparse PCO model. The for...

OBJECTIVE Surface roughness parameters of various intraocular lenses (IOLs) biomaterials using atomic force microscopy (AFM) are compared. Variation, if any, in the micro-roughness properties of different IOLs made up of the same biomaterial is also explored. Retrospective analysis of posterior capsular opacification (PCO) incidence has been followed up for a period of four years post IOL impla...

BACKGROUND Peritoneal absorption of CO(2) during abdominal insufflation in laparoscopy may disrupt the acid-base equilibrium and alter the physiological response to stress. Current nonventilated rodent models of laparoscopy do not manage the CO(2) load of pneumoperitoneum, but ventilated surgical rodent models are invasive (tracheotomy) and may independently induce the inflammatory response. ...
