First-trimester combined screening for trisomy 21 at 7-14 weeks' gestation.
OBJECTIVE: To establish an algorithm for first-trimester combined screening for trisomy 21 with biochemical testing from 7 to 14 weeks' gestation and ultrasound testing at 11-13 weeks. METHODS: This was a multicenter study ...
Prospective study evaluating performance of first-trimester combined screening for trisomy 21 using repeat sampling of maternal serum markers PAPP-A and free β-hCG.
OBJECTIVE: To prospectively evaluate the performance of first-trimester combined screening for trisomy 21 using the biochemical markers pregnancy-associated plasma protein-A (PAPP-A) and free beta-human chorionic gonadotropin ...
Use and perception of collars for companion cats in New Zealand.
AIMS: To investigate the use and utility of collars for companion cats in New Zealand, and to explore public perception of collar use. METHODS: An online questionnaire was distributed using emails and social media to members ...
Intraoperative aberrometry-based aphakia refraction in patients with cataract: status and options.
AIM: To explore the application of intraoperative wavefront aberrometry (IWA) for aphakia-based biometry using three existing formulae derived from autorefractive retinoscopy and introducing new improved formulae. METHODS: ...
GPCALMA: a Grid-based tool for mammographic screening.
OBJECTIVES: The next generation of high energy physics (HEP) experiments requires a GRID approach to a distributed computing system: the key concept is the Virtual ORGANISATION (VO), a group of distributed users with a ...
Intraocular lens opacification after corneal endothelial keratoplasty: electron microscopy and x-ray element spectroscopy analysis.
PURPOSE: To assess a newly recognized long-term complication of Descemet-stripping automated endothelial keratoplasty (DSAEK). SETTING: Plymouth Royal Eye Infirmary and Plymouth Electron Microscope Centre, Plymouth, United ...
Motor contagion during human-human and human-robot interaction.
Motor resonance mechanisms are known to affect humans' ability to interact with others, yielding the kind of "mutual understanding" that is the basis of social interaction. However, it remains unclear how the partner's ...
Any versus long-term prescribing of high risk medications in older people using 2012 Beers Criteria: results from three cross-sectional samples of primary care records for 2003/4, 2007/8 and 2011/12.
BACKGROUND: High risk medications are commonly prescribed to older US patients. Currently, less is known about high risk medication prescribing in other Western Countries, including the UK. We measured trends and correlates ...
Features of Blastocystis spp. in xenic culture revealed by deconvolutional microscopy.
Blastocystis spp. are common human enteric parasites with complex morphology and have been reported to cause irritable bowel syndrome (IBS). Deconvolutional microscopy with time-lapse imaging and fluorescent spectroscopy ...
