OBJECTIVES Posterior condylar offset (PCO) and posterior tibial slope (PTS) are critical factors in total knee arthroplasty (TKA). A computational simulation was performed to evaluate the biomechanical effect of PCO and PTS on cruciate retaining TKA. METHODS We generated a subject-specific computational model followed by the development of ± 1 mm, ± 2 mm and ± 3 mm PCO models in the posterior...

OBJECTIVE The aim of this study was to investigate whether polycystic ovary syndrome (PCOS) phenotype without polycystic ovaries (PCO) differs in terms of in vitro fertilization (IVF) outcomes compared with classic phenotypes. MATERIALS AND METHODS This retrospective controlled study included 262 patients who underwent IVF treatment with an indication of unexplained or tubal factor infertilit...

The research examined individual differences in people’s propensity to connectwith others (PCO). Ameasure of PCO, with components for making friends (strong ties), making acquaintances (weak ties), and joining others (bridging ties), was developed and tested in two studies involving 144 undergraduates and 197 health-care employees. PCO and its components were significantly positively associated...

Antarctic krill embryos and larvae were experimentally exposed to 380 (control), 1000 and 2000 µatm pCO₂ in order to assess the possible impact of ocean acidification on early development of krill. No significant effects were detected on embryonic development or larval behaviour at 1000 µatm pCO₂; however, at 2000 µatm pCO₂ development was disrupted before gastrulation in 90 per cent of embryos...

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...
