BACKGROUND AND OBJECTIVES Venous blood gas (VBG) analysis is a safer procedure than arterial blood gas (ABG) analysis and may be an alternative for determining acid-base status. The objective of this study was to examine the agreement between ABG and central VBG samples for all commonly used parameters in a medical intensive care unit (ICU) population. DESIGN, SETTING, PARTICIPANTS, & MEASURE...

INTRODUCTION Posterior capsule opacification (PCO) is a visually-disabling complication of cataract surgery. OBJECTIVE To estimate energy levels for capsulotomy in various subtypes of PCO (membranous, fibrous and fibro-membranous). MATERIALS AND METHODS A total of 215 patients with PCO were randomly selected and evaluated for Nd: Yag laser capsulotomy, after a quiet post-operative course of...

Background: The affordable protocol to prevent the severe OHSS in two groups of patients PCO syndrome and non PCO high responder. Methods and Materials: PubMed and Medline were searched from January 2000 till end of May 2014. This Study investigates whether the mild protocol is associated to prevent severe OHSS in infertile female. Results: According to this survey, 9 studies were included and ...

Effects of elevated pCO₂ on Emiliania huxleyi genetic diversity and the viruses that infect E. huxleyi (EhVs) have been investigated in large volume enclosures in a Norwegian fjord. Triplicate enclosures were bubbled with air enriched with CO₂ to 760 ppmv whilst the other three enclosures were bubbled with air at ambient pCO₂; phytoplankton growth was initiated by the addition of nitrate and ph...

PURPOSE Posterior capsule opacification (PCO) is a complication of cataract surgery resulting from the proliferation, migration, and epithelial-to-mesenchymal transition (EMT) of lens epithelial cells that remain associated with the lens capsule. These changes cause a loss of vision. The authors developed a chick embryo lens capsular bag model to study mechanisms involved in the onset of PCO. B...

OBJECTIVES The value of end-tidal PCO(2) monitoring during exercise in patients with chronic heart failure has not been elucidated. The present study was designed to examine end-tidal PCO(2) response to exercise and its relation to functional capacity in patients with chronic heart failure. METHODS AND RESULTS Maximal upright ergometer exercise with respiratory gas analysis and arterial blood...

BACKGROUND Hyperandrogenism (HA) has been linked with several components of metabolic syndrome (MetS). Few studies in Asian women have evaluated the important risk factors for and prevalence of MetS according to PCOS subtype. In this study, we investigated differences in metabolic parameters and the prevalence of MetS in two major phenotypic subgroups of PCOS in Korea. Furthermore, we investiga...

PURPOSE To determine if cyclooxygenase-2 (COX-2) is upregulated when lens epithelial cells (LEC) in clinical samples of cataracts and posterior capsule opacification (PCO) undergo epithelial-mesenchymal transition (EMT)-like changes. We also wanted to learn if inhibition of the enzymatic activity of COX-2 could prevent PCO formation. METHODS To ensure that EMT-like changes were occurring in L...

Manipulative studies have demonstrated that ocean acidification (OA) is a threat to coral reefs, yet no experiments have employed diurnal variations in pCO(2) that are ecologically relevant to many shallow reefs. Two experiments were conducted to test the response of coral recruits (less than 6 days old) to diurnally oscillating pCO(2); one exposing recruits for 3 days to ambient (440 µatm), hi...
