AIM The purpose of this study was to compare several parameters of root canal preparation using two different rotary nickel-titanium instruments: HERO 642 (Micro-Mega, Besancon, France) and Quantec SC (Tycom, Irvine, CA, USA). METHODOLOGY Fifty extracted mandibular molars with root canal curvatures between 20 micro and 40 micro were imbedded into a muffle(More)
The haemorheological parameters haematocrit (Hct), plasma viscosity (PV), red cell aggregation (RCA), red cell filterability (RCF), apparent whole blood viscosity (WBV), and fibrinogen were measured in 31 patients with retinal artery occlusion (RAO), 25 patients with anterior ischaemic optic neuropathy (AION), and 19 patients with giant cell arteritis(More)
In 83 patients with central retinal vein occlusion and branch vein occlusion we measured the haematocrit (HCT), plasma viscosity (PV), red cell aggregation (RCA), red cell filterability (RCF) and apparent whole blood viscosity (WBV). A control group (n = 41) was matched for sex, age, and cardiovascular risk factors. Measurements were performed before and(More)
In a prospective study, 48 eyes with non-ischaemic and 35 with ischaemic central retinal vein occlusion (CRVO) were treated by isovolaemic haemodilution (IHD). Two or more cardiovascular risk factors were present in 42% of patients with non-ischaemic and in 69% of patients with ischaemic CRVO (p less than 0.025). Nevertheless, IHD in no case caused serious(More)
Glutamine (GLN) appears to be an essential nutrient during organism development and critical illness. The aim of our study was to evaluate the effects of GLN and its generic preparation alanyl-glutamine-dipeptide (DIP) on the microcirculation in endotoxemia in rats and its effects on tonus or aortal rings in vitro. Male Lewis rats (n=40) were separated in 4(More)
BACKGROUND For biotechnological use of cells in tissue engineered applications, such as biohybrid renal devices, optimal culture conditions are required. Oxygen delivery is one of the most important cell determined system criterion for ex vivo applications. It is involved in the maintenance of highly oxygen-dependent renal tubular epithelial cells,(More)
Several behavioral rehabilitation strategies have been empirically validated in the treatment of schizophrenia and are now the psychosocial treatments of choice for chronic mental disorders. The stress-vulnerability model and an empirically based decision tree offer clinicians' guidance in prescribing strategies that are particularly relevant for each(More)
This study was an investigation of the role of cholecystokinin (CCK) in the stimulatory action of cholestyramine on rat exocrine pancreas. Postprandial CCK release was significantly enhanced by acute administration of cholestyramine (12.7 +/- 1.8 vs 3.7 +/- 0.5 pmol/L in controls). Over four weeks, rats were fed either regular diet or diet containing 6%(More)
