background. this study evaluated the effect of two prophylaxis techniques on the marginal gap of ci v resin-modified glass-ionomer restorations. methods. standard cl v cavities were prepared on the buccal surfaces of 48 sound bovine mandibular incisors in this in vitro study. after restoration of the cavities with gc fuji ii lc resin-modified glass-ionomer, the samples were randomly assigned to...

A microsampling cup procedure is described for rapid, precise determination of copper in plasma. Conventional Delves-cup atomic absorption spectrometry does not yield usable copper signals with blood plasma samples. Analytical sensitivity was improved 11-fold by use of cups fitted with an axial hole, a triangular cup-holding loop, and a smaller-bore absorption tube. The modified procedure yield...

The authors previously found that positively charged substances are less well-transported into the vitreous humor by transscleral iontophoresis than are negatively charged substances. There was more bubble formation in the eye cup with positively charged than with negatively charged substances. The authors hypothesized that these bubbles might account for the poorer conductance of the positivel...

background over the last decade there has been an increase in healthcare expenditures while at the same time the inequity in distribution of resources has grown. these two issues have urged the researchers to review the determinants of healthcare expenditures. in this study, we surveyed the determinants of health expenditures in economic cooperation organization (eco) countries.   methods we us...

The Deformation T-Cup (DT-Cup) is a modified 6-8 multi-anvil apparatus capable of controlled strain-rate deformation experiments at pressures greater than 18 GPa. Controlled strain-rate deformation was enabled by replacing two of the eight cubic "second-stage" anvils with hexagonal cross section deformation anvils and modifying the "first-stage" wedges. However, with these modifications approxi...

BACKGROUND Cancer of unknown primary (CUP) is diagnosed at the metastatic stage. We aimed to identify hidden primary cancers in CUP patients by comparison with cancers in family members. We take use of the fact that the cause of death in CUP patients is often coded as the cancer in the organ of fatal metastasis. PATIENTS AND METHODS Forty-one thousand five hundred and twenty-three CUP patient...

Two modifications of Malmstrom's cup were used in a study of the position of the cup in 500 vacuum extractor deliveries. The incidence of completely flexing applications varied from 0 to 92 per cent according to the level of the head and the position of the occiput when the cup was applied and, in occipito-posterior positions, the type of cup that was used. With mid-cavity occipito-posterior po...

Objectives. To determine the minimum lateral bone coverage required for securing stable fixation of the porous-coated acetabular components (cups) in hip dysplasia. Methods. In total, 215 primary total hip arthroplasties in 199 patients were reviewed. The average follow-up period was 49 months (range: 24-77 months). The lateral bone coverage of the cups was assessed by determining the cup cente...

Uncemented revision cups are widely used in revision hip arthroplasty; they have shown good results. We report the the short term outcome with the cementless Pinnacle revision cup. All acetabular revisions using a Pinnacle revision cup between January 2007 and March 2010 were included. In March 2012, clinical scores were determined and the latest radiographs were assessed. Revision and radiogra...

Digital photogrammetry was performed on stereophotographs of the optic nerve head of a modified Zeiss model eye in which optic cups of varying depths could be simulated. Experiments were undertaken to determine the impact of both photographic and ocular variables on the photogrammetric measurements of cup depth. The photogrammetric procedure tolerates refocusing, repositioning, and realignment ...
